(54) COOLING TOOL GRANULES
权利要求:
Claims (2) [1] The invention relates to a device for cooling a granulate of thermoplastic synthetic materials continuously supplied during its manufacture. A device for cooling granules, mainly of thermoplastic, synthetic materials, containing a pipe with loading and discharge patrols horizontally arranged on the base and equipped with a cooler tl, is known. its efficiency is low due to the lack of additional means to ensure the cooling effect of the granules. The purpose of the invention is to improve the efficiency of the device. This is achieved by the fact that, in the device for cooling the granules, predominantly of thermoplastic synthetic materials, there is a horizontal located on the base pipe with loading and injection nozzles, equipped with a cooler, the pipe is equipped with a tangential inlet connection in the lower part connected to the air supply system It is filled with a hole for the code of the Spirit, located in the upper part of the tube in its generous direction, and is equipped with a radial reflecting plate fixed to the inside light on the internal wall of the pipe for zsnoy positioning holes for the air outlet. In this case, the cooler is located at the outer tube of the pipe opposite the tangential nozzle. In addition, the tube is smashted with the possibility of tilting to the horizontal plane and vibration vibrations and is equipped with an oscillator. Moreover, the device is equipped with a mesh partition, sms tirovannoy in the pipe Before the tangential pipe. The cross-sectional area of the air outlets is larger than the cross-sectional area of the air inlet. FIG. 1 shows a general view of the device; On fng.2 - section aa of fig. 1. The device comprises a base 1, on which a pipe 2 is mounted, having a loading nozzle 3 and an outlet nozzle 4 with a flap 5. The loading nozzle 3 is connected to a cyclone 6. At the bottom of the pipe 2 a tangential nozzle 7 is fixed, which is connected to the system via a choke 8 filing 9. of air. The pipe 2 is made with air outlets 10 for air outlet, located in the upper part of the pipe in its longitudinal direction, covered with grids 11. The pipe is provided with a radial reflecting plate 12 fixed on the inner wall of the pipe behind the air outlet area. The pipe is also provided with a liquid cooler 13 located at the outer wall of the pipe opposite the tangential nozzle 7 of the inlet. To create vibrational oscillations, the device is equipped with a generator of 14 oscillations, mounted on the pipe end. In addition, the pipe is mounted with the possibility of inclination relative to the horizontal plane. A mesh partition 15 is mounted in the pipe in front of the tangential nozzle 7. The cross-sectional area of the air outlets 10 is larger than the cross-sectional area of the air inlet 16. The device works as follows. The hot granulate from the granulator (not shown in the drawings) j supplied through the piping system by means of compressed air, separates from the compressed air and falls through the charging port 3 into the pipe [2] 2. The injected granulate falls onto the mesh wall 15 and is captured by cooling air introduced tangentially into the pipe 2. In the pipe 2 on its wall 17, due to a tangential blowout, a predominant air pattern is formed in the direction of compression, which moves the granulate upward along the cooled wall 17 of the pipe. Depending on the value of the established flow of cooling air or behind the pieces, the granules are exposed to the cooling flow and, due to the curved surface of the wall 17 of the pipe, are subjected to strong and weak circulation and are cooled. When the granulate moves up the wall 17 of the pipe, besides direct cooling with cooling air, additional cooling of the granulate takes place due to contact with the cooled wall 17 of the pipe, and the outside wall can be cooled using the circulating, spraying or irrigating method. The path in the direction of the circumference is about 180–270, the cooling air and the entrainment of granulations meet the resistance of the radial reflecting plate 12. Due to the almost perpendicular impact on the reflecting plate 12 of air with a granule an air vortex appears in front of it. Since the reflecting plate 12 is located in the circumferential direction behind the zone of the air outlets 10, the air swirls that occur contribute to the discharge of hot exhaust air through the holes 11 covered with grids 11. Above the orifices of the Yu, you can place the kolpak connecting with the suction pipe and exhaust fan. Carried away by the air stream, up to the reflecting plate 12, is granulated once in contact with it and mixed by the air vortices that form, and then, under the action of its own weight, it again falls back onto the mesh partition 15. Then it is granulated again by cold air coming in through the tangential nozzle The wall 17 enters the upper part of the pipe. In order to remove the granulate from the pipe, it is vibrated by an oscillating generator 14. Invention 1. A device for cooling the granules, preferably It is made of thermoplastic synthetic materials containing horizontally., but located on the base of the pipe with loading and discharge nozzles, equipped with a cooler, which is different, so that in order to increase the efficiency of the device in operation, the pipe is equipped with a tangential nozzle fixed in its lower part the inlet, in communication with the air supply system, is provided with air outlets located at the top of the pipe in its longitudinal direction and is provided with a radial reflecting plate fixed hydrochloric the inner tube wall zone of the holes for arranging the air outlet. ,; 2. A pop device, 1, characterized in that the cooler is located at the outer wall of the pipe opposite the tangential nozzle. 3 A device according to Claims 1 and 2, characterized in that the pipe is smoked with the possibility of tilting to the horizontal plane and vibratory axial vibrations and is equipped with an oscillator. 4. The device according to PP. 1, 2, and 3, in that it is equipped with a mesh partition mounted in a pipe in front of the tangential nozzle. " five . Device on PP. 1,2,3 and 4, characterized in that the cross-sectional area of the air outlets is larger than the cross-sectional area of the air inlet.
