Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ceramic membrane filtration technology, and specifically relates to a raw material screening device for ceramic membrane production. Background Technology
[0002] Ceramic membranes are separation media with sieving efficiency, manufactured by sintering ceramic powder. Existing ceramic membranes using silica particles as raw materials require screening of the silica particles before compression molding and sintering. A diameter of 1 mm is generally preferred, and it can be as small as 0.03 mm smaller than the standard diameter. Screening devices are commonly used for this purpose. However, existing screening devices mostly separate particles using sieves, which have low efficiency and are prone to clogging. Utility Model Content
[0003] The purpose of this invention is to provide a raw material screening device for ceramic membrane production. It has a simple structure and accelerates the screening speed by rotating and vibrating the drive screening structure. It has high working efficiency, strong practicality, and is suitable for widespread application.
[0004] This utility model provides the following technical solution: it includes a tank and a screening bag. The screening bag has an open top and an array of mesh holes on its side walls and bottom. A top cover is threaded onto the top of the tank. A truss is fixedly installed below the tank. A rotating shaft is fixedly installed at the center of the bottom of the screening bag. A lower support is fixedly installed at the bottom of the rotating shaft. A connecting groove is provided at the bottom of the lower support. A connecting column is fixedly installed on the truss corresponding to the connecting groove. The bottom of the lower support is beveled around the connecting groove. A support rod is fixedly installed on the truss. The top of the support rod is slidably connected to the beveled surface.
[0005] A motor is fixedly installed at the center of the top cover. The output end of the motor is connected to a drive shaft. A clamping groove is fixedly installed at the top of the rotating shaft. A sliding block is fixedly installed at the lower end of the drive shaft. The sliding block is inserted into the drive shaft and slidably connected to it. A sealing ring is fixedly installed around the upper opening of the sieve bag. An upper ring groove is fixedly installed on the top cover corresponding to the sealing ring.
[0006] Preferably, the upper part of the sealing ring is pressed into the upper ring groove and sealed to it, and the middle part of the sealing ring is a concave ring with thin walls made of rubber.
[0007] Preferably, the sidewall of the connecting column fits into the inner wall of the connecting groove, and its upper end has a gap with the bottom of the connecting groove.
[0008] Preferably, a spiral propulsion plate is arranged around the rotating shaft, and a through feed port is provided at the upper cover.
[0009] The beneficial effects of this utility model are as follows: It has a simple structure, accelerates the screening speed by rotating and vibrating the driving screening structure, resulting in high working efficiency and strong practicality. Specifically:
[0010] (1) This utility model is equipped with a tank. After the raw material is injected into the screening bag, the motor runs. When it is working, the motor drives the rotating shaft to rotate, which in turn drives the screening bag to rotate. When the screening bag rotates, the lower seat below it rotates. Since the bottom of the lower seat is a sloping surface, when it rotates, the support rod lifts the screening bag. Every time the lower seat rotates once, the screening bag moves up and down once, making the screening bag rotate and bump, so as to speed up the screening speed. The bumpy screening bag screen is not easy to get clogged.
[0011] (2) This utility model is equipped with a sealing ring. When the screen bag is installed, the sealing ring is pressed into the upper ring groove of the upper cover. When it moves upward, the screen bag presses the inner concave ring of the sealing ring and bends and folds. At the same time, the clamping groove rises and the sliding block goes into the clamping groove, so that the rise of the screen bag is not affected and the upper cover and the screen bag remain closed.

[0021] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] See Figure 1-3 The system includes a tank body 1 and a screening bag 3. The screening bag 3 has an open top and an array of mesh holes on its side walls and bottom for screening raw materials. A through-feed inlet 9 is provided at the top cover 2. The top cover 2 is threaded onto the top of the tank body 1. A truss 6 is fixedly installed at the bottom of the tank body 1. A rotating shaft 5 is fixedly installed at the center of the bottom of the screening bag 3. A spiral propulsion plate 10 is arranged around the rotating shaft 5. The spiral propulsion plate 10 can be selectively installed. A lower connecting seat 12 is fixedly installed at the bottom of the rotating shaft 5. The bottom of the lower connecting seat 12 has a connecting groove 13. The truss 6... A connecting column 14 is fixedly provided at the corresponding connecting groove 13. The side wall of the connecting column 14 fits against the inner wall of the connecting groove 13 to prevent the screen bag 3 from tilting. There is a gap between the upper end of the connecting column 14 and the bottom of the connecting groove 13, so that the connecting groove 13 can slide on the connecting column 14. The bottom of the lower seat 12 is cut at the connecting groove 13. A support rod 16 is fixedly provided on the truss 6. The top of the support rod 16 is slidably connected to the cut surface. When the lower seat 12 rotates, the support rod 16 lifts the inclined sliding surface 15, so that the lower seat 12 moves up and down.
[0023] See Figure 2 ,4 A motor 4 is fixedly installed at the center of the upper cover 2. The output end of the motor 4 is connected to a drive shaft 17. A clamping groove 18 is fixedly installed at the top of the rotating shaft 5. A sliding block 19 is fixedly installed at the lower end of the drive shaft 17. The sliding block 19 is inserted into the drive shaft 17 and slidably connected to it, so that the rotating shaft 5 is lifted without obstruction and without affecting the drive of the motor 4. A sealing ring 8 is fixedly installed around the upper opening of the screen bag 3. An upper ring groove 7 is fixedly installed on the upper cover 2 corresponding to the sealing ring 8. The upper part of the sealing ring 8 is pressed into the upper ring groove 7 and sealed to it. The middle part of the sealing ring 8 is an inner concave ring 11. The wall of the inner concave ring 11 is thin and made of rubber. The sealing ring 8 is pressed into the upper ring groove 7 of the upper cover 2. When it rises, the screen bag 3 bends and folds the inner concave ring 11 of the sealing ring 8, which does not affect the rise of the screen bag 3.
[0024] This utility model relates to a raw material screening device for ceramic membrane production. It has a simple structure and accelerates the screening speed by rotating and vibrating the drive screening structure. It has high working efficiency, strong practicality, and is suitable for widespread application.
[0025] For specific usage, please refer to... Figure 1-4 After the raw material is injected into the screening bag 3, the motor 4 starts. When it is working, the motor 4 drives the rotating shaft 5 to rotate, which in turn drives the screening bag 3 to rotate. When the screening bag 3 rotates, the lower receiving seat 12 below it rotates. Since the bottom of the lower receiving seat 12 is a sloping sliding surface 15, the support rod 16 lifts the screening bag 3 when it rotates. The screening bag 3 moves up and down once for every rotation of the lower receiving seat 12. When the screening bag 3 is installed, the sealing ring 8 is pressed into the upper ring groove 7 of the upper cover 2. When it moves upward, the screening bag 3 bends and folds the inner concave ring 11 of the sealing ring 8. At the same time, the clamping groove 18 rises and the sliding block 19 goes deep into the clamping groove 18, so that the rise of the screening bag 3 is not affected. When the motor 4 drives it, the screening bag 3 rotates and bumps to speed up the screening speed, and the bumping screening bag 3 screen is not easy to get clogged.
