A siphon for papermaking

Abstract

This utility model relates to a siphon for papermaking. When pulp needs to be transported, the siphon is installed above the pulp tank via a frame, and the inlet end of the siphon body extends into the pulp tank. Then, the siphon body is operated, allowing the pulp in the pulp tank to enter the siphon body through the inlet end and then be discharged through the outlet end. Before the pulp enters the inlet end, large particles in the pulp are isolated by a filter cover. The finer pulp enters the filter cover through the filter holes and is then sucked in by the siphon body. Because the particles in the pulp are sticky, they easily stick to the outside of the filter cover, affecting the pulp's entry into the filter cover through the filter holes. The washing component can be operated to wash the filter cover in the pulp tank, thereby removing the particles that were originally stuck to the filter holes, allowing the pulp to enter the filter cover for siphoning more effectively. This reduces the chance of siphon clogging and allows the siphon to transport pulp more efficiently.

Detailed Implementation

[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 4As shown, a papermaking siphon of the present invention includes a frame 1, a siphon body and a filter mechanism 5. The siphon body is connected to the frame 1. One end of the siphon body is set as the liquid inlet 9 and the other end of the siphon body is set as the liquid outlet 8. The filter mechanism 5 is provided outside the liquid inlet 9 and is connected to the frame 1.

[0026] The filtration mechanism 5 includes a filter cover 509 and a rinsing assembly. The filter cover 509 is sleeved on the outside of the liquid inlet end 9 of the siphon body. The upper part of the rinsing assembly is connected to the frame 1, and the lower part of the rinsing assembly is detachably connected to the filter cover 509. A plurality of filter holes 510 are arranged around the outside of the filter cover 509.

[0027] The working principle of this utility model is as follows: When pulp needs to be conveyed, the siphon is installed above the pulp tank through the frame 1, and the inlet end 9 of the siphon body is extended into the pulp tank. Then the siphon body is operated, so that the pulp in the pulp tank enters the siphon body through the inlet end 9 and is discharged through the outlet end 8. Before the pulp enters the inlet end 9, the large particles in the pulp are isolated by the filter cover 509. The finer pulp enters the filter cover 509 through the filter holes 510 and is then sucked in by the siphon body. Since the particles in the pulp are sticky, they are easy to stick to the outside of the filter cover 509, which affects the pulp from entering the filter cover 509 through the filter holes 510. The washing component can be operated to make the washing component drive the filter cover 509 to wash in the pulp tank, so that the particles that were originally stuck to the filter holes 510 are removed from the filter holes 510 after washing, so that the pulp can enter the filter cover 509 for siphoning better.

[0028] Furthermore, the washing assembly includes a rotation drive 501, a linkage shaft 502, and a vertical moving assembly. One vertical moving assembly is provided on each side of the filter cover 509. The bottom of each vertical moving assembly is detachably connected to the filter cover 509. The upper part of each vertical moving assembly is connected to the frame 1. One vertical moving assembly is connected to the other vertical moving assembly via the linkage shaft 502. The rotation drive 501 is driven to the linkage shaft 502.

[0029] As can be seen from the above description, when the filter cover 509 needs to be washed, the rotating drive 501 can be operated, so that the rotating drive 501 drives the up and down moving component to move through the linkage shaft 502, so that the up and down moving component drives the filter cover 509 to move back and forth, thereby making the particles adhering to the filter cover 509 better removed from the filter hole 510, and facilitating the pulp to enter the filter cover 509 through the filter hole 510 for siphon transport.

[0030] Furthermore, the vertical moving assembly includes a sliding frame 503, a roller 512, a drive wheel 506, a first connecting rod 505, a second connecting rod 508, a first sliding seat 504, and a second sliding seat 507. The sliding frame 503 is connected to the frame 1. The upper part of the sliding frame 503 is provided with a first sliding groove, and the first sliding seat 504 is slidably connected to the first sliding groove. The lower part of the sliding frame 503 is provided with a second sliding groove, and the second sliding seat 507 is slidably connected to the second sliding groove. The first sliding seat 504 is connected to the first connecting rod 506. 05 is connected to the second sliding seat 507. The lower part of the second sliding seat 507 is detachably connected to the top of the filter cover 509 through the second connecting rod 508. The drive wheel 506 is provided between the first sliding seat 504 and the second sliding seat 507. The drive wheel 506 is connected to the linkage shaft 502. The drive wheel 506 is provided with three sets of protrusions 511. A roller 512 can be rotatably mounted on both the first sliding seat 504 and the second sliding seat 507. The protrusions 511 and the rollers 512 are movably connected.

[0031] As can be seen from the above description, when the filter cover 509 needs to be washed, the rotating drive 501 drives the drive wheel 506 to rotate through the linkage shaft 502. During the rotation of the drive wheel 506, the protrusion 511 alternately squeezes the rollers 512 on the first sliding seat 504 and the second sliding seat 507, so that the first sliding seat 504 and the second sliding seat 507 slide back and forth on the first and second sliding grooves under the pressure. When the second sliding seat 507 moves, it drives the filter cover 509 to move up and down continuously through the second connecting rod 508, so that the filter cover 509 is washed in the pulp tank.

[0032] Furthermore, the siphon body includes a tube 3, a first shut-off valve 10, a flow regulating valve 4, and a vacuum generating assembly. The tube 3 is connected to the frame 1. One end of the tube 3 is configured as the liquid inlet 9, and the other end of the tube 3 is configured as the liquid outlet 8. The first shut-off valve 10 is provided on the liquid inlet 9, and the flow regulating valve 4 is provided on the liquid outlet 8. The vacuum generating assembly is connected to the tube 3.

[0033] As can be seen from the above description, when it is necessary to transport the pulp in the pulp tank, the vacuum generating component can be operated to evacuate the inside of the pipe body 3. Then, the first shut-off valve 10 and the flow regulating valve 4 are opened, so that the pulp in the pulp tank enters the inside of the pipe body 3 through the inlet end 9 and is discharged from the pipe body 3 through the outlet end 8. When it is necessary to adjust the flow rate of the outlet end 8, the flow regulating valve 4 can be operated to control the amount of liquid discharged from the outlet end 8.

[0034] Furthermore, the vacuum generating assembly includes a vacuum pump 2, an extraction pipe 6, and a second shut-off valve 7. An extraction port is provided on the pipe body 3. One end of the extraction pipe 6 is connected to the extraction port, and the vacuum pump 2 is connected to the other end of the extraction pipe 6. The second shut-off valve 7 is provided inside the extraction pipe 6.

[0035] As can be seen from the above description, when it is necessary to evacuate the inside of the pipe body 3, the first shut-off valve 10 and the flow regulating valve 4 are used to seal the inlet end 9 and the outlet end 8. Then, the second shut-off valve 7 is opened and the vacuum pump 2 is run, so that the vacuum pump 2 evacuates the inside of the pipe body 3 through the suction pipe 6. Then, the second shut-off valve 7 is run to seal one end of the suction pipe 6. Then, the first shut-off valve 10 and the flow regulating valve 4 are run to open the inlet end 9 and the outlet end 8, so that the pulp flows into the outlet end 8 through the inlet end 9.

[0036] Furthermore, the tube body 3 is made of a transparent material.

[0037] As can be seen from the above description, it is beneficial to observe the pulp conveying through the transparent tube 3 and to detect blockages and other problems in a timely manner.

[0038] Furthermore, it also includes a PLC controller, which is electrically connected to both the siphon body and the filter mechanism 5.

[0039] As can be seen from the above description, it is beneficial to adjust the parameters of the papermaking siphon through the PLC controller, and makes it more convenient for operators to operate the papermaking siphon. Example 1
