[0027] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] Example:

[0030] See also Figure 1 The present embodiment discloses a HMPP sewage treatment tank with cleanable interior, comprising a tank body 1, a support ring 2, an outer frame 3, a filter screen 4 and a pull rope 5. The tank body 1 is a hollow cylindrical structure, and the tank body 1 is vertically arranged in an underground sewage well. A detachable top cover is arranged on the top of the tank body 1, and a sewage inlet is arranged on the top cover, and an outlet is arranged at the bottom of the tank body 1.

[0031] A support ring 2 is provided in the middle of the tank body 1, and the support ring 2 is in a convex state on the inner wall of the tank body 1. The outer frame 3 is also annular, and the outer frame 3 can be placed on the support ring 2. At the same time, a filter screen 4 is provided inside the outer frame 3.

[0032] One end of the pull rope 5 is fixedly set on the top of the outer frame 3, and the other end of the pull rope 5 extends toward the sewage inlet and is placed on the top of the tank body 1. When the top cover is installed on the tank body 1, the top cover can press the pull rope 5 against the top of the tank body 1, thereby preventing the end of the pull rope 5 from falling into the tank body 1.

[0033] In this embodiment, a support ring 2 is provided in the tank body 1, and the filter screen 4 is provided on the outer frame 3, and then the outer frame 3 is placed on the support ring 2, so as to realize the filtering function of the treatment tank. When the filter screen 4 needs to be cleaned, the filter screen 4 and the outer frame 3 can be pulled out of the tank body 1 by pulling the pull rope 5 from the mouth of the tank body 1, so that the filter screen 4 can be cleaned on the ground, and after the cleaning is completed, the outer frame 3 and the filter screen 4 can be put back on the support ring 2. This technical solution has the advantages of high cleaning efficiency and low labor for the treatment tank.

[0034] Preferably, at least three pull ropes 5 are arranged around the outer frame 3 . When the outer frame 3 and the filter screen 4 are pulled up, all the pull ropes 5 work together to enable the outer frame 3 and the filter screen 4 to move smoothly toward the top of the tank body 1 .

[0035] In addition, the outer side surface of the outer frame 3 is in close contact with the inner wall of the tank body 1, so that when the pull rope 5 pulls the outer frame 3 and the filter screen 4 upward, the outer side edge of the outer frame 3 can scrape the debris attached to the inner wall of the tank body 1 onto the filter screen 4, thereby cleaning the inner wall of the tank body 1.

[0036] In one specific embodiment:

[0037] The inner wall of the tank body 1 is provided with an inclined guide groove 6, and the outer frame 3 is provided with a protrusion matching the guide groove 6. By setting the guide groove 6, when the pull rope 5 pulls the outer frame 3 upward, the outer frame 3 can move upward in a rotating state, thereby preventing the slag on the tank body 1 from getting stuck in the movement of the outer frame 3. The principle is that when the outer frame 3 rotates, the slag will be subjected to a lateral force and an upward force, so that the slag is separated from the inner wall of the tank body 1 under the action of multiple forces.

[0038] Preferably, by setting the cross-section of the guide groove 6 and the cross-section of the protrusion to be a triangular structure, the internal space of the guide groove 6 can be reduced, thereby reducing the slag deposited in the guide groove 6.

[0039] In another specific embodiment:

[0040] A guide hole 7 is also provided on the tank body 1 , one end of which is located on the top of the tank body 1 , and the other end of which is located on the inner wall of the tank body 1 . Meanwhile, one end of the pull rope 5 away from the outer frame 3 passes through the guide hole 7 .

[0041] In this embodiment, by setting a guide hole 7, the position of one end of the pull rope 5 can be fixed. In the process of pulling the outer frame 3 and the filter screen 4 to move toward the top of the tank body 1, there is no need to move the position of the pull rope 5. At the same time, by setting the guide hole 7, the force acting on the end of the pull rope 5 can be in a vertically upward state, so that the force on the pull rope 5 changes in the guide hole 7.

[0042] In another specific embodiment:

[0043] A plurality of shovel plates 8 are provided on the top of the outer frame 3. The shovel plates 8 are tightly attached to the inner wall of the tank body 1 and are in a triangular prism structure. The outer frame 3 rotates at an angle α when it moves from the support ring 2 to the top of the tank body 1. The number of shovel plates 8 is greater than or equal to 360° / α.

[0044] In this embodiment, as the pull rope 5 pulls the outer frame 3 upward, the guide groove 6 and the protrusion cause the outer frame 3 to rotate. Therefore, by providing a shovel plate 8, the shovel plate 8 can clean the inner wall of the tank body 1 during the rising process of the outer frame 3. The cleaning effect is stronger than the cleaning of the tank body 1 by the outer side of the top of the outer frame 3.

[0045] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
