    A screw conveyor apparatus suitable for conveying and processing flowable materials such as particulate materials and slurries, for example, which incorporates cleaning or scraping elements for dislodging the accumulation of materials from the surfaces of the helical flight. The apparatus comprises an elongated housing defining a conveying chamber in which a helical flight is rotatably supported formed with a central axially extending bore through at least a portion of the length thereof and a shaft slidably disposed in the bore and reciprocable and rotatable relative to the helical flight. A series of scraper elements are mounted on the shaft adjacent to the leading and trailing surfaces of the helical flight and a drive mechanism is provided for rotating the helical flight and the shaft. A power mechanism is provided for intermittently or continuously reciprocating the shaft relative to the helical flight to effect a traversing movement of the scraper elements along the helical surfaces to effect dislodgement of any accumulated material therefrom.

    1 The invention relates to lifting and transport equipment, namely, screw conveyors used to transport various materials with simultaneous processing through heat exchange, and can be applied in various industries. Screw conveyors are known that contain a housing in which two working bodies with screw surfaces are placed rotates in one direction, while the working bodies are installed with mutual contact of the screw surfaces, as a result of which there is a mutual cleaning of these surfaces lj. The closest technical solution to the invention is a screw conveyor comprising a cylindrical body with loading and unloading nozzles, a rotating spiral vane located inside it, a shaft and an actuator inside the spiral vane. A disadvantage of the known conveyor is that when it is used in technological processes associated with the processing of the transported material by heating to high temperatures, the adhesion of the transported material to the spiral blade occurs, and this leads to a deterioration in the processing of the material. The purpose of the invention is to ensure the cleaning of the spiral blade of the screw conveyor during material transport. This goal is achieved by the fact that a screw conveyor containing a cylindrical body with loading and unloading nozzles, a rotating spindle, a rotary blade located in it, is located inside the spiral blade, and the drive shaft is equipped with scraper elements located on the shaft adjacent to the front and rear surfaces of the spiral blade wherein the shaft is mounted with the possibility of reciprocating movement and rotation relative to the spiral blade. In addition, the scraper elements are arranged at intervals equal to half the pitch of the spiral 82 blade, and are made in the form of plates corresponding to the contour of the spiral blade. The shaft is equipped with a heart-shaped cam connected to the drive. At the same time, spiral grooves are made on the shaft with a pitch corresponding to the step of the spiral blade, and the shaft has balls placed in the spiral grooves. In addition, the screw conveyor has a heat exchange chamber to control the temperature of the material being conveyed. FIG. 1 shows a screw conveyor, a section; FIG. 2 shows section A-A in FIG. one ; in fig. 3 shows the node I in FIG. one; in fig. 4 shows a section BB in FIG. 1. The screw conveyor consists of a cylindrical body 1 with loading 2 and unloading 3 branch pipes, mounted on base 4 using vertical support consoles 5 and 6. The discharge pipe 3 is made conical in shape and connected to body 1 by means of flange 7 and washer 8. On the opposite The discharge end of the housing 1 has a flange 9, which is bolted 1O to the tubular sleeve 11. Inside the housing 1, which is a closed chamber, is placed a spiral blade 12, which at one end is connected to the drive coupling 13, The bearing is rotatably mounted on a bearing 14 placed in a vertical support plate 15 mounted on the base 4. The spiral blade 12 and the drive sleeve 13 are fixed along the longitudinal axis of the conveyor by means of a ring 16. placed in an annular groove 17 made in a tubular sleeve 11. Drive coupling 13 also has a chevron seal 18 with a packing nut 19, which is threaded to the outer portion of the tubular sleeve 11. The spiral blade 12 is made with a central hole 20 in which the shaft 21 is placed, also extending into utri drive sleeve 13 and mounted for reciprocating movement and rotation relative to the helical blade 12. The helical blade 3 12 has a front (working) 22 and a rear (HEPA bochuyu) 23 surface. Adjacent to the front 22 and rear 23 surfaces of the spiral blade 12 are the scraper elements 24 mounted on the shaft 21. In this embodiment of the screw conveyor, the skid elements 24 are located at the shaft 21 at intervals equal to half the pitch of the spiral blade 12, and made in the form of plates corresponding to the contour of the spiral blade. The scraper elements 24 may not be located along the entire length of the shaft 21, but only in those areas where the transported material ocp6ei) Ho sticks to the spiral surfaces of the blade 12. At one end of the shaft 21 is fixed a heart-shaped cam 25 mounted on a stand 26 on the base 4. The shaft 21 is connected through a gear reducer (not shown) with a drive 27. The heart-shaped cam 25 is placed at one end into a fork 28, having two oppositely disposed pushers 29 placed in the guide 30, made in the body of the heart-shaped cam 25 Securing The cam-shaped cam 25 with the shaft 21 is carried out by means of a fastening screw 31 with a thrust washer 32 and a thrust ball underpin 33. The shaft 21 has spiral grooves 34 with a pitch corresponding to the pitch of the spiral blade 12. The helical grooves 34 are placed opposite the spiral grooves 34 34 of the shaft 21 in the body of the drive clutch 13 there are shallow depressions corresponding to the spiral-4 grooves 34 of the shaft 21. These balls 35 serve to transfer torque from the drive clutch 13 to the shaft 21. The screw conveyor also has a heat exchanger To measure 36, cover the active part of the cylindrical body 1 through which heat exchange medium, for example steam, can circulate. Due to this, the material located in the housing 1 can be heat exchanged to control the temperature of the material, including heating the latter to a high temperature in order to ensure its thermal restructuring. Screw conveyor works as follows. When the actuator 27 is turned on, the heart-shaped cam 25 begins to rotate, and the shaft 21, through the hinged swivel plug 28, moves along its reciprocating-progressively from the front position (shown by solid lines) to the standby position (shown by dotted lines) with its simultaneous rotation due to the spiral grooves 34 of the balls 35. Simultaneously with the activation of the rotational drive of the heart-shaped cam 25, the drive clutch 13 and the spiral blade 12 connected to it start to rotate. Therians starts movable spiral blade 12 to the discharge pipe 3. Since the shaft 21 thus reciprocates with rotation movement postupatelnoe embodied thereon scraper elements 24 perform a similar movement of the working surfaces and purified helical blade 12 from adhering transported material. Depending on the type of material being transported, the heart-shaped cam 25 controls the reciprocating movement of the shaft 21 and can change the speed of rotation of the shaft from 0 to 2 revolutions per minute to achieve the required rotation cleaning. This is carried out continuously or with pre-excitation of the drive motor by means of an idle time regulator (not shown) with the provision of periodic reciprocating motion of the shaft. The invention makes it possible to ensure the cleaning of the spiral blade of the screw conveyor during the transportation of the material, as well as simultaneously expose the material to heat exchange to regulate its temperature.
