Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a precision filtration device for liquid anti-cracking agents. Background Technology

[0002] During the production, storage, and transportation of liquid crack inhibitors, solid particles and other impurities often become mixed in due to raw material residues, external dust intrusion, or container wear. If used directly without effective treatment, these impurities will not only reduce the uniformity of the crack inhibitor's dispersion in the substrate and weaken its crack resistance, but may also cause blockage or wear on construction equipment (such as spray guns, metering pumps, and delivery pipelines), affecting construction efficiency and project quality.

[0003] Existing filtration devices mostly adopt a single filtration precision design. If only coarse filtration is set, it cannot effectively intercept micron-sized fine particles, resulting in insufficient product purity. On the other hand, if high-precision filtration is pursued blindly, it will easily cause the filter media to clog rapidly and the system pressure drop to rise sharply. This not only shortens the filter element life but also significantly increases the frequency of cleaning or replacement. It is difficult to adapt to the wide particle size distribution of impurities in liquid anti-cracking agents and affects the efficiency of continuous operation.

[0004] Therefore, a precision filtration device for liquid anti-cracking agents needs to be designed. Utility Model Content

[0005] In order to overcome the shortcomings of existing single-precision filters, which are unable to simultaneously achieve particle retention and anti-clogging, and cannot adapt to the wide distribution of impurity particle size, thus affecting the efficiency of continuous operation, this utility model provides a precision filtration device for liquid anti-cracking agents.

[0006] Technical solution: A precision filtration device for liquid anti-cracking agents, comprising a support base, a filter barrel, an inlet pipe, a cover plate, guide rods, filter plate one, an outlet pipe, a connecting plate, a filter cylinder, filter plate two, and filter plate three. The filter barrel is fixedly connected inside the support base, and multiple inlet pipes are fixedly connected to the outside of the filter barrel. A cover plate is placed on top of the filter barrel, and multiple guide rods are fixedly connected to the bottom of the cover plate. Filter plate one is slidably connected between the multiple guide rods. An outlet pipe is fixedly connected to the bottom of the filter barrel. A connecting plate is fixedly connected to the outside of the inlet pipe and the bottom of the outlet pipe. Filter cylinders are snapped into the inside of each inlet pipe. Filter plate two is fixedly connected to the inside of each filter cylinder. Filter plate three is fixedly connected to the inside of the outlet pipe.

[0007] In one embodiment, the filter bucket is further provided with a sliding plate, a limiting rod, and a return spring. Multiple limiting rods are fixedly connected to the outside of the filter bucket, and a sliding plate is slidably connected to the outside of each limiting rod. A sliding groove is opened inside each liquid inlet pipe, and the sliding plate slides into the sliding groove. A return spring is connected between the filter bucket and the sliding plate.

[0008] In one embodiment, the device also includes an arc-shaped magnet and a magnetic ring. An arc-shaped magnet is fixedly connected to the top of each sliding plate, and a magnetic ring is fixedly connected to the outside of each liquid inlet pipe. The arc-shaped magnets are magnetically attracted to the magnetic rings on the same side.

[0009] In one embodiment, the system further includes a slag discharge pipe, a servo motor, and spiral blades. The slag discharge pipe is fixedly connected to the outside of the liquid discharge pipe, and a connecting plate is also fixedly connected to the outside of the slag discharge pipe. A servo motor is installed outside the liquid discharge pipe, and the output shaft of the servo motor passes through the liquid discharge pipe and is rotatably connected to it. Spiral blades are connected to the output shaft of the servo motor, and the spiral blades are located inside the slag discharge pipe and above the filter plate.

[0010] In one embodiment, a transparent plate is also included, with the transparent plate fixedly connected inside the slag discharge pipe.

[0011] In one embodiment, a bellows is also included, with the filter barrel and the sliding plate both connected by the bellows, and the limiting rod and the return spring are both sleeved inside the bellows.

[0012] Beneficial effects: 1. By sequentially intercepting large, medium and micron-sized impurities through filter plate two, filter plate one and filter plate three, the system achieves efficient removal of impurities of different particle sizes, significantly improving the purity and dispersion stability of liquid anti-cracking agent. This solves the problem that existing single-precision filters cannot simultaneously achieve particle retention and anti-clogging, and cannot adapt to the wide distribution of impurity particle sizes, thus affecting the efficiency of continuous operation.

[0013] 2. This utility model sets up a servo motor and spiral blades. The output shaft of the servo motor rotates to drive the spiral blades to rotate. The spiral blades, through the spiral structure, can push the fine impurities trapped in the filter plate into the slag discharge pipe and towards the pipe opening at regular intervals or as needed, reducing manual intervention and improving the system's automation level and operational continuity.

Detailed Implementation

[0021] Example: A precision filtration device for liquid crack inhibitors, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the system includes a support base 1, a filter barrel 2, an inlet pipe 201, a cover plate 3, guide rods 4, a first filter plate 5, an outlet pipe 6, a connecting plate 7, a filter cylinder 14, a second filter plate 15, and a third filter plate 17. The filter barrel 2 is welded inside the support base 1. Inlet pipes 201 are welded to both the left and right sides of the filter barrel 2. A cover plate 3 is placed on top of the filter barrel 2 to prevent external dust and foreign objects from falling into the filter barrel 2 and contaminating the liquid. Two axially distributed guide rods 4 are welded to the bottom of the cover plate 3. The first filter plate 5 is slidably connected to the two guide rods 4 via a sliding groove. 5 can float slightly up and down along the guide rod 4, which can disturb the liquid flow field and effectively prevent impurities from accumulating in a local area of ​​the filter plate 5, so that it can more evenly and fully intercept medium-sized impurities in the liquid. The bottom of the filter barrel 2 is welded with an outlet pipe 6. The outside of the inlet pipe 201 and the bottom of the outlet pipe 6 are both welded with connecting plates 7. The inlet pipe 201 is fitted with a filter cylinder 14. The filter cylinder 14 is welded with a filter plate 2 15. The outlet pipe 6 is welded with a filter plate 3 17. The aperture of the filter plate 2 15, filter plate 1 5 and filter plate 3 17 decreases in sequence.

[0022] like Figure 2 , Figure 3 and Figure 5As shown, it also includes a sliding plate 8, an arc-shaped magnet 9, a magnetic ring 11, a limiting rod 12, a return spring 13, and a bellows 21. Limiting rods 12 are welded to both the left and right sides of the filter barrel 2. The limiting rods 12 are slidably connected to the sliding plate 8 via grooves. The limiting rods 12 provide linear sliding guidance for the sliding plate 8, preventing it from shifting during pulling or resetting. Sliding grooves 10 are provided inside the liquid inlet pipe 201, into which the sliding plate 8 slides. A return spring 13 connects the filter barrel 2 and the sliding plate 8. 3. Arc-shaped magnets 9 are welded to the top of the sliding plate 8, and magnetic rings 11 are welded to the outside of the liquid inlet pipe 201. The arc-shaped magnets 9 are magnetically attracted to the magnetic rings 11 on the same side, so as to achieve quick disassembly, cleaning or replacement of filter plate 2 15 without tools, which greatly reduces maintenance time and cost. Corrugated pipes 21 are connected between the filter barrel 2 and the sliding plate 8. The limit rod 12 and the return spring 13 are both sleeved inside the corrugated pipe 21. The corrugated pipe 21 can protect the return spring 13 from impurities and prevent the return spring 13 from rusting.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, it also includes a slag discharge pipe 16, a servo motor 18, a spiral blade 19, and a transparent plate 20. The slag discharge pipe 16 is welded to the outside of the liquid outlet pipe 6, and a connecting plate 7 is also welded to the outside of the slag discharge pipe 16. The servo motor 18 is installed on the outside of the liquid outlet pipe 6. The output shaft of the servo motor 18 passes through the liquid outlet pipe 6 and is rotatably connected to it. The spiral blade 19 is connected to the output shaft of the servo motor 18. The spiral blade 19 is located inside the slag discharge pipe 16 and above the filter plate 17. A transparent plate 20 is welded to the front inside the slag discharge pipe 16, which allows the operator to monitor the accumulation of impurities in real time and start the slag discharge program in time to avoid the risk of blockage.

[0024] When this device is needed, the operator first connects the external liquid anti-cracking agent delivery pipeline to the connecting plate 7 on the inlet pipe 201, connects the pure liquid collection device to the connecting plate 7 on the outlet pipe 6, and connects the impurity and waste collection device to the connecting plate 7 on the slag discharge pipe 16. After the connection is completed, the external delivery pump can be turned on to introduce liquid anti-cracking agent into the inlet pipe 201. The liquid anti-cracking agent first flows through the filter cartridge 14, and the second filter plate 15 directly intercepts larger particles of impurities in the liquid. The preliminarily filtered liquid then enters the filter barrel 2 along the inlet pipe 201. The liquid entering the filter barrel 2 impacts the surface of the first filter plate 5, and the first filter plate 5 can float slightly up and down along the guide rod 4. This floating can disturb the liquid flow field and effectively prevent impurities from accumulating in a local area of ​​the first filter plate 5. The liquid filtered by the first filter plate 5 flows to the bottom of the filter barrel 2 and passes through the third filter plate 17 before entering the outlet pipe 6. The third filter plate 17 accurately intercepts small particles of impurities in the liquid, and the impurities intercepted by the third filter plate 17 will accumulate on top of it.

[0025] When impurities accumulate to a large extent, the servo motor 18 can be started. The output shaft of the servo motor 18 rotates, driving the spiral blades 19 to rotate. The spiral blades 19 push the impurities in the slag discharge pipe 16 to the outlet through the spiral structure, and discharge them through the connecting plate 7 on the outside of the slag discharge pipe 16. The transparent plate 20 allows the operator to visually observe the accumulation of impurities in the slag discharge pipe 16. The pure liquid anti-cracking agent flows into the collection device connected below through the liquid outlet pipe 6. After all the liquid anti-cracking agent has been filtered, the external delivery pump is turned off to stop the liquid introduction. After observing that no liquid flows out of the liquid outlet pipe 6, the servo motor 18 is turned off. Finally, the connection of each pipe connecting plate 7 is disconnected, and the collection device and waste collection device are separated from the device.

[0026] When the filter cartridge 14 needs to be disassembled, push the sliding plate 8 towards the side closest to the filter barrel 2. The return spring 13 and the bellows 21 are gradually compressed, and the sliding plate 8 slides into the sliding groove 10 of the liquid inlet pipe 201 until the arc magnet 9 and the corresponding magnetic ring 11 are magnetically attracted, fixing the sliding plate 8 in the liquid inlet pipe 201. Then, pull the filter cartridge 14 inward to disengage it from the liquid inlet pipe 201. After that, directly remove the filter cartridge 14 for cleaning or replacement. Then, put the cleaned or replaced filter cartridge 14 back into the liquid inlet pipe 201 and move it outward to lock it onto the connecting pipe. Then, pull the sliding plate 8 outward to disengage the arc magnet 9 from the magnetic ring 11. The sliding plate 8 slides out of the sliding groove 10 and resets. The return spring 13 and the bellows 21 return to their original positions. If the filter plate 5 needs to be cleaned, remove the cover plate 3 and directly remove the filter plate 5 for cleaning or replacement. After completion, put it back. This completes the use of this device.
