Description

Technical Field

[0001] This application relates to the technical field of granular material transportation, and specifically relates to a star-shaped discharger. Background Art

[0002] Star-shaped dischargers are divided into three categories: ordinary type, pressure-resistant type, and high-temperature resistant type. The discharger can be driven at a constant speed to continuously discharge materials at a controlled rate, or driven at an indefinite speed, using the star-shaped discharger as a feeder.

[0003] The star-shaped discharger can discharge materials quantitatively and continuously. The materials in the upper hopper fall by their own weight and fill the gaps between the blades. As the blades rotate, the materials are discharged from the upper part. The characteristic of the star-shaped discharger is that the end of the rotor blade is lined with a polytetrafluoroethylene sealing strip, which can reduce the contact gap between the end of the blade and the inner wall of the shell. Moreover, after wear, the end of the blade can be conveniently adjusted to still maintain good contact with the inside of the shell, having a better air locking function.

[0004] When the star-shaped discharger is in use, before the granular materials are transported to the star-shaped discharger, they will come into contact with the water vapor in the air inside, and caking will occur inside the granular materials. At this time, when the caked materials are transported into the inside of the star-shaped discharger together, it will cause the blades inside the star-shaped discharger to not rotate smoothly, resulting in the subsequent inability to drive the materials to be transported quantitatively and continuously. Summary of the Utility Model

The extrusion and crushing mechanism includes a box body fixed at the inlet of the tank body, cylinders arranged on both sides of the outer wall of the box body. The box body is vertically through, and a rectangular hole is provided on the outer wall of the box body. The extrusion and crushing mechanism also has an extrusion block fixed on the output end of the cylinder and a baffle plate rotatably connected to the top of the extrusion block through a shaft. Multiple groups of convex blocks are integrally formed on the surface of the extrusion block, and the other end of the baffle plate fits on the inner wall of the box body.

[0007] By adopting the above technical solution, it is possible to quickly crush the caked materials.

[0008] Preferably, the partition plate horizontally arranged inside the box body is provided with strip-shaped holes for the falling of granular materials, and the partition plate is arranged below the extrusion block.

[0009] By adopting the above technical solution, the granular materials can fall through the strip-shaped holes, and the caked materials can be temporarily placed.

[0011] By adopting the above technical solution, it can play a role in connecting with the subsequent structure.

[0012] Preferably, the extrusion and crushing mechanism further includes elastic ropes sleeved on the first block and the second block at both ends respectively.

[0025] The following combines the attached Figures 1-4 to further elaborate on the embodiments of the present application.

[0026] Embodiment 1

[0027] Please refer to Figures 1-4 , this embodiment provides a technical solution: a star-shaped discharger, including: a tank body 1 and an extrusion and crushing mechanism 4;

[0028] An inlet is provided above the tank body 1, which can provide materials to be transported to the inside of the tank body 1 through the inlet, and an outlet is provided below the tank body 1. The materials inside the tank body 1 can be output subsequently through the outlet. The extrusion and crushing mechanism 4 is arranged at the inlet of the tank body 1. When the materials are caked, the extrusion and crushing mechanism 4 can quickly crush the caked materials.

[0029] The extrusion and crushing mechanism 4 includes a box body 401 fixed at the inlet of the tank body 1. The box body 401 is connected to the inlet of the tank body 1 by bolts to provide stable connection between structures. The box body 401 is through from top to bottom, which can provide materials to pass through the box body 401 and then be transported to the inside of the tank body 1. A rectangular hole is provided on the outer wall of the box body 401, which can provide subsequent fixation of the internal structure. A transparent plate 402 is fixed inside the rectangular hole of the box body 401. The transparent plate 402 is connected to the inner wall of the rectangular hole of the box body 401 by bolts, so as to provide people to observe the inside of the box body 401 from the outside. The size of the transparent plate 402 is adapted to the rectangular hole of the box body 401, which can play an effective airtightness to prevent particulate materials from flowing out through the gap between the transparent plate 402 and the rectangular hole of the box body 401.

[0030] A partition plate 403 horizontally arranged inside the box body 401, the partition plate 403 is connected to the inner wall of the box body 401 by bolts. A strip-shaped hole for the falling of granular materials is provided on the partition plate 403. The partition plate 403 can provide passage for the falling of granular materials and can temporarily stop the caked materials above the partition plate 403. Cylinders 404 are arranged on both sides of the outer wall of the box body 401. The cylinders 404 are connected to the box body 401 by bolts. An extrusion block 405 fixed on the output end of the cylinder 404. The extrusion block 405 connected to the output end of the cylinder 404 can move reciprocally in the horizontal direction. Multiple groups of convex blocks are integrally formed on the surface of the extrusion block 405, which can squeeze the caked materials, so as to crush the caked materials.

[0031] A baffle 406 rotatably connected to the top end of the extrusion block 405 by a shaft. The baffle 406 can be realized through the shaft, so that the angle of the extrusion block 405 changes during the displacement process, and the other end of the baffle 406 fits against the inner wall of the box body 401. The baffle 406 can provide shielding for the granular materials. A first block 407 welded to both ends of the inner wall of the box body 401. The first block 407 can play a role in connecting structures. A second block 408 welded to the outer wall of the baffle 406. The second block 408 can play a role in connecting structures. And the cross-sectional shapes of the first block 407 and the second block 408 are both "U" shapes, which can provide stable connection of structures and avoid the phenomenon of falling off. Elastic ropes 409 sleeved on the first block 407 and the second block 408 at both ends respectively. The elastic ropes 409 can drive the structures connected to one side to move through their own material characteristics.

[0032] When the materials are transported into the box body 401, at this time, the granular materials will fall through the partition plate 403 into the inside of the tank body 1 for subsequent work, and the caked materials will stay above the partition plate 403. At this time, the transparent plate 402 is used to observe the condition of the caked materials inside the box body 401. The cylinder 404 is started to drive the extrusion block 405 to move in the horizontal direction, and the caked materials are squeezed and crushed by the movement of the extrusion block 405. During the movement of the extrusion block 405, the baffle 406 connected by a shaft above is pulled by the elastic rope 409 between the first block 407 and the second block 408, so that one end of the baffle 406 always fits against the inner wall of the box body 401.

[0033] Embodiment 2

[0034] Please refer to Figures 1-3 This embodiment provides a technical solution: a star-shaped unloader, including: a driving motor 2 and blades 3;

[0035] The driving motor 2 is fixedly arranged on the outer wall of the tank body 1. The driving motor 2 is connected to the outer wall of the tank body 1 by bolts, so as to drive the structure connected to the output end to rotate. The blade 3 is connected to the output end of the driving motor 2 through a shaft, and the blade 3 is arranged inside the tank body 1. The blade 3 can drive the materials inside the tank body 1 to be quantitatively conveyed through the connection with the driving motor 2.

[0036] After the granular materials are conveyed into the tank body 1, by starting the driving motor 2, during the operation of the driving motor 2, it can drive the blade 3 connected to the output end to rotate, so as to drive the granular materials inside the tank body 1 to be quantitatively discharged from the bottom discharge port through the blade 3.

[0037] The implementation principle of a star-shaped discharger of the present application is as follows:

[0038] First of all, after the materials are conveyed into the inside of the box body 401, at this time, the granular materials will fall through the partition plate 403 into the inside of the tank body 1 for subsequent work, and the caked materials will stay above the partition plate 403. At this time, the transparent plate 402 is used to observe the condition of the caked materials inside the box body 401, and the air cylinder 404 is started to drive the extrusion block 405 to move horizontally, and the caked materials are crushed by the movement of the extrusion block 405.

[0039] Secondly, during the movement of the extrusion block 405, the baffle plate 406 connected by a shaft above is pulled by the elastic cord 409 between the first block 407 and the second block 408, so that one end of the baffle plate 406 always fits against the inner wall of the box body 401.

[0040] Finally, after the granular materials are conveyed into the tank body 1, by starting the driving motor 2, during the operation of the driving motor 2, it can drive the blade 3 connected to the output end to rotate, so as to drive the granular materials inside the tank body 1 to be quantitatively discharged from the bottom discharge port through the blade 3.
