Description

Technical Field

[0001] This utility model relates to the field of PTFE powder processing technology, specifically a high-shear wet grinding pump for PTFE powder. Background Technology

[0002] High-shear wet grinding pumps for PTFE (polytetrafluoroethylene) powder need to possess high wear resistance, corrosion resistance, and efficient shearing capacity to ensure that the PTFE powder achieves a uniform and fine dispersion during wet grinding. Traditional high-shear wet grinding pumps, after prolonged use, may cause PTFE particles to agglomerate or become unevenly distributed. Substandard particles can affect the uniform and fine dispersion effect, thus presenting certain shortcomings. Therefore, we propose a new high-shear wet grinding pump for PTFE powder. Utility Model Content

[0004] Therefore, the technical solution adopted by this utility model is as follows: a high-shear wet grinding pump for PTFE powder, including a pump casing, a screening assembly, a screening frame, and a return hose. A feed pipe is fixedly installed on the left side of the pump casing, and a discharge pipe is fixedly installed on the top of the pump casing. The screening assembly includes a right screening cylinder fixedly installed on the left side of the discharge pipe, a left screening cylinder inserted and connected to the outside of the right screening cylinder, and a discharge hose fixedly installed on the left side of the left screening cylinder. The screening frame includes a bracket inserted and connected to the left screening cylinder, a filter screen fixedly installed on the bracket, and a handle fixedly installed on the right side of the bracket. The return hose is fixedly installed at the bottom of the left screening cylinder, and an electric valve is fixedly installed on the return hose.

[0005] Preferably, a drive motor is fixedly installed on the right side of the pump casing, and the drive motor is fixedly connected to the rotor inside the pump casing.

[0006] Preferably, the right screening cylinder has a plurality of slots on its exterior, and the plurality of slots are equidistantly distributed.

[0007] Preferably, the left screening cylinder is threaded with a fastening knob, and both fastening knobs are inserted into the slot.

[0009] Preferably, a sealing ring is fixedly provided on the inner side of the left screening cylinder, and the sealing ring is a rubber ring.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: The discharge pipe of this utility model can transport the ground mixture to the right and left screening cylinders. After being transported, it can pass through the filter screen of the screening frame to filter out substandard particles. Then, the return hose is opened to transport the substandard particles to the feed pipe for re-grinding, ensuring a uniform and fine dispersion effect. At the same time, the fastening knob can be rotated. When the fastening knob is disengaged from the slot, the right screening cylinder can be disassembled, and the screening frame can be directly removed for maintenance and replacement. The right screening cylinder is also movable. After being moved to a suitable position, the fastening knob can be rotated to insert into the slot, achieving the effect of adjusting the length of the screening component, thus having a wide range of applications.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a high-shear wet grinding pump for PTFE powder.

[0022] Example 1:

[0023] Reference Figure 1-4 This is the first embodiment of the present invention. This embodiment provides a high-shear wet grinding pump for PTFE powder, including a pump housing 100, a screening assembly 200, a screening frame 300, and a return hose 400.

[0024] Specifically, a feed pipe 102 is fixedly installed on the left side of the pump casing 100, a discharge pipe 103 is fixedly installed on the top of the pump casing 100, and a drive motor 101 is fixedly installed on the right side of the pump casing 100. The drive motor 101 is fixedly connected to the rotor inside the pump casing 100. In use, the raw material can be transported into the pump casing 100 through the feed pipe 102, and the grinding mixture inside the pump casing 100 can be discharged through the discharge pipe 103 for use. Then, the drive motor 101 can drive the rotor to rotate at high speed, and the rotor can generate shearing force in conjunction with the fixed stator for grinding.

[0025] Specifically, the screening assembly 200 includes a right screening cylinder 201 fixedly disposed on the left side of the discharge pipe 103, a left screening cylinder 202 inserted and connected to the outside of the right screening cylinder 201, and a discharge hose 204 fixedly disposed on the left side of the left screening cylinder 202. The right screening cylinder 201 has several slots 205 evenly distributed on its exterior. The left screening cylinder 202 is threaded with two fastening knobs 203, both of which are inserted into the slots 205. A stop block 206 for blocking the screening frame 300 is fixedly disposed on the inner side of the left screening cylinder 202. The stop block 206 has a ring-shaped structure. A sealing ring 207, which is a rubber ring, is provided. During use, the cooperation between the right screening cylinder 201 and the left screening cylinder 202 forms a sealed space for screening. The screened mixture can be discharged through the discharge hose 204. The left screening cylinder 202 can be fixed to the right screening cylinder 201 by the cooperation of the fastening knob 203 and the slot 205. The length of the screening assembly 200 can be adjusted for use. The screening frame 300 can be blocked by the stop block 206 for installation. The sealing ring 207 improves the sealing between the right screening cylinder 201 and the left screening cylinder 202 to prevent leakage.

[0026] Specifically, the screening frame 300 includes a support 301 inserted into the left screening cylinder 202, a filter screen 302 fixedly mounted on the support 301, and a handle 303 fixedly mounted on the right side of the support 301. In use, the support 301 and the filter screen 302 can be moved by the handle 303 to install and remove the screening frame 300. The filter screen 302 can filter out substandard particles, thereby allowing the substandard particles to be ground again to ensure a uniform and fine dispersion effect.

[0027] Specifically, the return hose 400 is fixedly installed at the bottom of the left screening cylinder 202, and an electric valve 401 is fixedly installed on the return hose 400. In use, by controlling the opening of the electric valve 401, the substandard particles can be transported through the return hose 400 to the feed pipe 102 so that the qualified particles can be ground again.

[0028] The working principle and usage process of this utility model are as follows: During use, the mixture ground by the pump housing 100 enters the right screening cylinder 201 and the left screening cylinder 202 of the screening assembly 200 through the discharge pipe 103. Then, the mixture passes through the filter screen 302 of the screening frame 300. When passing through, the filter screen 302 will filter out the substandard particles. After that, the electric valve 401 can be opened. After opening, the substandard particles will enter the feed pipe 102 through the return hose 400. Finally, they will enter the pump housing 100 for secondary grinding. When the screening frame 300 needs to be disassembled, the two fastening knobs 203 can be rotated until the two fastening knobs 203 are completely disengaged from the slot 205. Then, the left screening cylinder 202 is moved to the left until the left screening cylinder 202 is completely disengaged from the right screening cylinder 201. After disengagement, the handle 303 can be gripped and force applied. The handle 303 will drive the bracket 301 to disengage from the left screening cylinder 202, and the screening frame 300 can be disassembled.
