Detailed Description

As shown in figures 1-4, the improved device of the wastewater treatment sludge screw pump is mainly improved in that a detachable water inlet pipe 9 is arranged on one side of a sewage inlet 8 at the upper end of a pump body 1; the tail part of the motor 3 of the pump body 1 is provided with a blower 11.

The water inlet pipe 9 is arranged, and the sludge blocked on the pump body 1 can be flushed away by adding clean water; through setting up air-blower 11, can make motor 3 dispel the heat fast, reduce motor 3's temperature, avoid burning out.

The improvement point of the device is suitable for most screw pumps and has strong universality because the application is only an improvement on the external structure of the sludge screw pump.

For ease of understanding, the present application specifically describes the improvement of the present application by taking the "single screw pump" patent with application number "201821968159.2" as an example.

In the above patent, a single-screw pump includes the pump body 1, installs even axostylus axostyle 2 in the pump body 1, and 1 outside both sides of the pump body are provided with motor 3 and stator 4 respectively, are provided with rotor 5 in the stator 4, and rotor 5 is connected with even axostylus axostyle 2 through first universal joint 6, and motor 6 is connected with even axostylus axostyle 2 through second universal joint 7. The upper end of the pump body 1 is provided with a sewage inlet 8, and one side of the pump body 1 is detachably provided with a water inlet pipe 9.

The joint of the water inlet pipe 9 and the sewage inlet 8 adopts a detachable connecting structure. Specifically, the connector comprises a first threaded sleeve 17 at the end of the water inlet pipe 9 and a second threaded sleeve 18 at one side of the sewage inlet 8, wherein the diameter of the second threaded sleeve 18 is the same as that of the through hole at one side of the sewage inlet 8, and the second threaded sleeve can move left and right along the through hole. The first threaded sleeve 17 and the second threaded sleeve 18 are in threaded connection. The first thread bush 17 and the second thread bush 18 are both provided with a limiting block 19, wherein the limiting block 19 on the first thread bush 17 keeps a certain interval with the side wall of the sewage inlet 8, and the limiting block 19 on the second thread bush 18 is positioned on the inner side of the sewage inlet 8 and attached to the inner side wall of the sewage inlet 8. A compression spring 20 is sleeved outside the sewage inlet 8 between the two limit blocks 19, and the compression spring 20 is in a compression state. The second thread bushing 18 around the compression spring 20 is sleeved with a pressure plate 21 and a sealing ring 22. The limiting block 19 on the second threaded sleeve 18 can only be pressed on the inner wall of the sewage inlet 8 by the acting force of the compression spring 20, and the sealing ring 22 on the left side is pressed on the sealing ring 22 on the right side of the end part of the limiting block 19 of the first threaded sleeve 17 in the ring groove of the sewage inlet 8 by the acting force of the compression spring 20 through the two end sleeve pressing plates 21 and the sealing ring 22, so that water leakage at two connecting parts can be avoided.

Because the industrial wastewater has certain corrosivity, after the second thread bush 18 is corroded, the second thread bush can be screwed down and taken out from the upper end of the sewage inlet 8 for replacement.
