Abstract
Description
Technical Field
[0001] The present application relates to the field of sewage treatment equipment, and in particular to a pipeline clearing device. Background Art
[0002] The filter press uses a special filter medium to apply a certain pressure to the material, so that the liquid is dialyzed out. It is a kind of mechanical equipment commonly used for solid-liquid separation. During the operation of the filter press, the material is pumped into the filter press from the feed pipe. As the material entering the filter press increases, the material concentration in the feed pipe gradually increases. The material in the feed pipe is prone to sedimentation. Therefore, it is usually necessary to backflush or backwash the feed pipe. Backflush or backwashing increases the process flow, prolongs the process time, and affects the solid-liquid separation efficiency. Utility Model Content
[0003] In order to reduce the impact of the backflushing or backwashing process of the filter press feed pipe on the solid-liquid separation efficiency, the present application provides a pipeline clearing device.
[0004] The present application provides a pipeline clearing device that adopts the following technical solution:
[0005] A pipeline blockage clearing device comprises a connecting pipe and a spring, wherein the connecting pipe comprises a horizontal pipe section and a vertical pipe section, one end of the vertical pipe section is connected to the horizontal pipe section, the spring is installed on the inner side of the horizontal pipe section, the outer contour of the spring abuts against the inner circumferential wall of the horizontal pipe section, one end of the horizontal pipe section is closed, a driving member is installed on the closed end of the horizontal pipe section, and the driving member is used to drive the spring to rotate around its own center line; one end of the vertical pipe section away from the horizontal pipe section and one end of the horizontal pipe section away from the closed end are used to connect to the feed pipe of the filter press.
[0006] By adopting the above technical solution, the connecting pipe is connected to the feed pipe of the filter press. When the filter press is fed, the sewage containing sludge passes through the horizontal pipe section and the vertical pipe section of the connecting pipe. By using the driving member to drive the spring to rotate, the spring can drive the sludge inside the horizontal pipe section to reduce the sludge deposition in the horizontal pipe section, and can save the backwashing or backwashing process, which is conducive to improving the efficiency of the filter press in treating solid-liquid mixtures.
[0007] Optionally, the driving member is a motor, and the motor is installed on the outside of the horizontal pipe section.
[0008] By adopting the above technical solution, the motor is installed on the outside of the horizontal pipe section, which can reduce the contact area between the motor and sewage and is beneficial to protecting the motor.

On the other hand, by setting a conical pipe section near the closed end of the horizontal pipe section, it is difficult for sludge to stay at the position of the horizontal pipe section near the closed end, so as to further reduce the sludge siltation.

[0012] By adopting the above technical solution, there is a rotational fit clearance between the output shaft of the motor and the main structure of the motor. By setting a baffle on the output shaft of the motor, the situation where sewage in the horizontal pipe section directly washes the rotational fit clearance of the motor can be reduced, so that the motor is protected.
[0013] Optionally, the baffle is an annular structure, the baffle has a taper, and the outer convex surface of the baffle faces away from the motor.
[0014] By adopting the above technical solution, when the water in the horizontal pipe section flows to the motor, the water flow is guided by the outer convex surface of the baffle, so as to reduce the pressure loss during the flow of sewage.

[0018] By adopting the above technical solution, when the spring rotates, the two limiters contact the corresponding arc rods alternately, and the arc rods have a guiding and limiting effect on the limiters, so that the spring is not easy to move along the axial direction, which makes the rotation of the spring more stable. The two arc rods are arranged at the top of the horizontal pipe section, which is not easy to hinder the flow of sludge in the horizontal pipe section.
[0019] Optionally, the limiting member is a plate-shaped structure, and the limiting member is provided with a guide notch, and the guide notch is adapted to the arc rod.
[0020] By adopting the above technical solution, the limiting member cooperates with the arc rod through the guiding notch, so that the arc rod has a guiding effect on the limiting member.

[0032] The following is combined with Figure 1-5 This application is described in further detail.
[0033] Example 1
[0034] The present application discloses a pipeline blockage clearing device. Figure 1 The pipeline clearing device includes a connecting pipe 1, which includes a horizontal pipe section 11 and a vertical pipe section 12. One end of the vertical pipe section 12 is connected to the horizontal pipe section 11, and one end of the vertical pipe section 12 away from the horizontal pipe section 11 is set to an upward or downward state according to the on-site installation layout of the filter press. In this embodiment, it is specifically set to an upward state.
[0035] A spring 2 is provided in the horizontal pipe section 11, and the outer contour of the spring 2 abuts against the inner circumferential wall of the horizontal pipe section 11. An end plate 13 is provided at one end of the horizontal pipe section 11. A driving component is installed on the end plate 13. The driving component is a motor 3. The motor 3 is integrated with a reducer. The motor 3 is located on the outside of the horizontal pipe section 11. The output shaft of the motor 3 penetrates the end plate 13 and is connected to one end of the spring 2 through a coupling 31. The motor 3 and the end plate 13 jointly close the end of the horizontal pipe section 11. The motor 3 is used to drive the spring 2 to rotate around its own center line.
[0036] One end of the vertical pipe section 12 away from the horizontal pipe section 11 and one end of the horizontal pipe section 11 away from the motor 3 are used to connect to the feed pipe 6 of the filter press.
[0037] The implementation principle of a pipeline clearing device according to an embodiment of the present application is as follows: a connecting pipe 1 is connected to a feed pipe 6 of a filter press, and when the filter press is fed, sewage containing sludge passes through a horizontal pipe section 11 and a vertical pipe section 12 of the connecting pipe 1. By using a driving member to drive the spring 2 to rotate, the spring 2 can drive the sludge inside the horizontal pipe section 11, which is beneficial to reducing the sludge deposition in the horizontal pipe section 11, and can save backwashing or backwashing processes, which is beneficial to improving the efficiency of the filter press in treating solid-liquid mixtures.
[0038] Example 2
[0039] Reference Figure 2 The difference between this embodiment and embodiment 1 is that a conical pipe section 14 is provided at one end of the horizontal pipe section 11 close to the motor 3, and the motor 3 is installed at the small end of the conical pipe section 14; the connecting part between the vertical pipe section 12 and the horizontal pipe section 11 is connected to the large end of the conical pipe section 14, and the end of the horizontal pipe section 11 away from the closed end is the feeding end.
[0040] Sewage enters from the end of the horizontal pipe section 11 away from the closed end, and leaves from the end of the vertical pipe section 12 away from the horizontal pipe section 11. The conical pipe section 14 can reduce the deposition of sludge at the closed end of the horizontal pipe section 11.
[0041] Reference Figure 2 and Figure 3 The output shaft of the motor 3 is provided with a baffle 32, and a gap is left between the edge of the baffle 32 and the inner peripheral wall of the connecting pipe 1. The baffle 32 is an annular structure, and the baffle 32 has a taper, and the outer convex surface of the baffle 32 is away from the motor 3. A plurality of guide vanes 33 are provided on the side of the baffle 32 away from the motor 3, and the plurality of guide vanes 33 are distributed in a circular array around the axis of the motor 3, and the surface of the guide vane 33 maintains a non-planar relationship with the axis of the motor 3.
[0042] There is a rotation fit clearance between the output shaft of the motor 3 and the main structure of the motor 3, and the baffle 32 can prevent the water flow in the horizontal pipe section 11 from directly flowing to the rotation fit clearance of the motor 3, so that the motor 3 is protected. When the water flows through the surface of the baffle 32, it is guided by the guide plate 33, so that the water flow forms a vortex to disturb the sludge deposited in the horizontal pipe section 11.
[0043] Example 3
[0044] Reference Figure 4 , Figure 5 and Figure 6The difference between this embodiment and embodiment 2 is that an end of the spring 2 away from the driving member is fixedly connected to an inclined rod 21, and the two ends of the inclined rod 21 are respectively located on both sides of the center line of the spring 2 and are staggered along the length direction of the spring 2; the inner wall of the horizontal pipe section 11 is provided with two arc rods 4, and the two arc rods 4 are spaced apart along the length direction of the horizontal pipe section 11, and the curvature center of the two arc rods 4 coincides with the center line of the horizontal pipe section 11, the arc angle of the arc rod 4 is greater than the straight angle, and the midpoint of the arc rod 4 is located at the top of the horizontal pipe section 11; the two ends of the inclined rod 21 are respectively provided with limit members 5, the limit members 5 are plate-shaped structures, and the wide side of the limit members 5 is parallel to the center line of the spring 2, the two limit members 5 correspond to the two arc rods 4 respectively, the limit members 5 are plate-shaped structures, and the limit members 5 are provided with guide notches 51, and the guide notches 51 are adapted to the arc rods 4.
[0045] The limiting member 5 is used to be slidably connected with the corresponding arc rod 4 along the extension direction of the arc rod 4; when the spring 2 rotates, the two limiting members 5 contact the corresponding arc rod 4 alternately, so that the end of the spring 2 away from the motor 3 is limited in the axial direction, which is beneficial to reduce the axial movement of the spring 2 and make the spring 2 rotate more smoothly.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
