A plurality of scrapers are arranged on the inner side wall of the tank body, one side of the scraper is in contact with the inner side wall of the tank body, a motor compartment is arranged at the center of the bottom of the inner cavity of the tank body, the motor compartment drives the scraper to rotate to scrape off the impurities on the inner wall of the tank body, realizes the cleaning of the inner wall of the tank body, a water distribution pipe is arranged on the top of the motor compartment, a plurality of water outlet pipes are fixedly connected to the outer ring of the water distribution pipe, and a high-pressure nozzle is connected to one end of each water outlet pipe. The high-pressure nozzle can spray water flow to clean the impurities on the inner wall of the tank body which are not easy to be washed away.

[0005] In order to better remove the impurities on the inner wall of the tank body in the prior art, a specially prepared cleaning liquid is also sprayed onto the inner wall of the tank body to impact the impurities adhering to the inner wall of the tank body. However, in the prior art, the cleaning liquid used for flushing the tank wall is directly discharged from the water outlet of the tank body, and a large amount of cleaning liquid is consumed during the entire flushing process. The tank body needs to be cleaned frequently during the entire use cycle, and the consumption of a large amount of cleaning liquid leads to high total cleaning cost. SUMMARY

[0006] The present application provides a circulating flushing equipment to solve the technical problem that the consumption of cleaning liquid is large when the tank body is cleaned by using a high-pressure water gun in the prior art, and the cleaning cost is high during the entire use cycle of the tank body.

[0007] To solve the above problems, the circulating flushing equipment provided by the present application adopts the following technical scheme: A circulating flushing equipment, comprising: a rotating shaft for rotating a water spraying device installed outside the rotating shaft and arranged to spray water towards the inner wall of the tank; a water spraying device rotatably installed outside the rotating shaft and arranged to spray water towards the inner wall of the tank; Further comprising: a water storage tank with an open top end and a reverse conical top portion, the water storage tank being slidably installed in the tank along the axial direction of the tank, the middle portion of the water storage tank being rotatably sleeved on the rotating shaft, and the top end edge of the water storage tank being arranged to abut against the inner wall of the tank; a filter screen installed on the top portion of the water storage tank, the middle portion of the filter screen being rotatably installed with a support, the support being fixed in position with the filter screen along the axial direction of the tank, and the support being rotatably sleeved outside the rotating shaft; a driving mechanism arranged outside the tank and in transmission connection with the rotating shaft to control the rotation of the rotating shaft; the water spraying device being arranged above the filter screen, slidably installed outside the rotating shaft along the axial direction of the rotating shaft, and fixed in position with the support along the axial direction of the rotating shaft, the water spraying device being provided with a water inlet pipe extending into the water storage tank through the support, and the water spraying device and the water inlet pipe being connected with a water pump; during cleaning, the water storage tank is moved along the axial direction of the rotating shaft by the rotating shaft, the water spraying device is moved synchronously with the water storage tank, and the water spraying device is rotated by the rotating shaft, the water pump pumps out the cleaning liquid that falls back to the water storage tank through the filter screen and sprays the cleaning liquid onto the inner wall of the tank.

[0008] According to the above technical scheme, when the inner wall of the tank is cleaned, a certain amount of cleaning liquid is stored in the water storage tank in advance, the water pump can pump out the cleaning liquid in the water storage tank and spray it onto the inner wall of the tank, and the impurities on the inner wall of the tank can be washed. By driving the rotating shaft to rotate, the water storage tank and the water spraying device can be moved up and down, so that each area on the inner wall of the tank can be washed. The cleaned liquid falls back to the water storage tank after being filtered by the filter screen, and is pumped out by the water pump and sprayed on the inner wall of the tank again. The cleaning liquid in the water storage tank can be recycled, and the whole cleaning process does not consume a large amount of cleaning liquid, which can reduce the cleaning cost.

The outer side wall of the rotating shaft 2 is provided with external threads, and the outer side wall of the rotating shaft 2 is also provided with two guide grooves 201 extending along the axis direction of the rotating shaft 2 at an interval of 180°.

[0034] The top end of the rotating shaft 2 is connected to a limiting plate 3, which is arranged on a support frame 4 clamped between the main body portion and the top cover of the tank 1, so as to realize the axial positioning of the rotating shaft 2 inside the tank 1, and the rotating shaft 2 and the support frame 4 can rotate relative to each other.

[0035] As shown in Figure 6As shown, the water storage tank 5 is in a whole cylindrical shape, the top end of the water storage tank 5 is open, and a spiral sleeve 18 penetrates through the water storage tank 5 vertically. The top of the water storage tank 5 is in an inverted conical shape, and two sockets 501 are arranged on the inverted conical part at intervals of 180°. Two arc-shaped drainage outlets are arranged on the bottom wall of the water storage tank 5 in opposition. The edge of the top end of the water storage tank 5 is used to be in close contact with the inner side wall of the tank body 1, so that the impurities on the inner side wall of the tank body 1 can be pre-scraped when the water storage tank 5 moves downward.

[0036] The spiral sleeve 18 is spirally sleeved on the outer side of the rotating shaft 2, and the two sockets 501 are respectively buckled on the two slide rails 101 on the inner side wall of the tank body 1. When the rotating shaft 2 rotates, the water storage tank 5 can be driven to move in the vertical direction.

[0037] A supporting ring 12 in a circular ring shape is further arranged on the top of the inner wall of the water storage tank 5, and the supporting ring 12 has an open port. Two connecting bolts 13 are arranged on both sides of the open port of the supporting ring 12, and two symmetrically arranged connecting bolts 13 are also arranged on the other side of the open port. The head of each connecting bolt 13 is downward, the connecting bolt 13 is slidably arranged on the supporting ring 12, and the elastic member two 14 is connected between the connecting bolt 13 and the supporting ring 12.

The elastic element 16 is located between the sleeve housing 30 and the push rod 32.

[0041] When the water tank 5 moves to the bottom of the tank body 1, the push rod 32 first pushes the sealing plate 17 upward to open the drain port, allowing all the liquid in the water tank 5 to flow into the bottom of the tank body 1. Then, the sealing plate 29 contacts the bottom surface of the water tank 5, sealing the drain port. Subsequently, the water tank 5 continues to move downward, squeezing the liquid in the tank body 1 into the space between the outer circumferential wall of the water tank 5 and the inner circumferential wall of the tank body 1, thus cleaning the top of the outer circumferential wall of the water tank 5.

[0042] like Figure 6 As shown, multiple comb teeth 10 are vertically connected to the bottom wall of the water storage tank 5, arranged radially at intervals along the water storage tank 5.

The handle 241 is rotatably mounted on the mounting plate 25, and the direction of rotation of the handle 241 is consistent with its own extension direction. A torsion spring connects the handle 241 and the mounting plate 25. Figure 4 , Figure 5 As shown, a push plate 243 is connected to the bottom of the handle 241, and the push plate 243 is located on one side of the bristles 242.

[0045] like Figure 4 , Figure 10As shown, the filter screen includes two screen plates 23, which are semi-annular and oppositely spliced together, and the middle portions of the two screen plates 23 are inserted into the annular slot 901, and the two screen plates 23 are spliced together to form an annular structure with a gap 231, which is opposite to the open port.

[0046] As shown, the impurity box 11 is placed at the gap 231, and the top end of the impurity box 11 is provided with two flanges, the impurity box 11 is arranged on the filter screen through the two flanges, and is sleeved on the outside of the corresponding connecting bolt 13 and the support ring 12 fixed by the connecting nut.

[0047] The box wall of the impurity box 11 is made of mesh, which can leave impurities and pass liquid, and a plurality of perforations are further provided on the bottom box wall of the impurity box 11, and the plurality of combs 10 are respectively inserted into the perforations. When the impurity box 11 is removed, the impurities on the combs 10 can be scraped off by the bottom box wall of the impurity box 11 and collected in the impurity box 11.

When the handle 241 is about to move to the comb 10 while the support base 9 is rotating, the bearing plate 243 first contacts and is pushed by the push rod 34 to swing, and when the bottom end of the bearing plate 243 is higher than the push rod 34, the bearing plate 243 moves above the push rod 34 and keeps an inclined state to slide above the push rod 34. In the above process, the handle 241 is driven to rotate by the bearing plate 243, so that the bristles 242 are swung to form an acute angle with the comb 10, so that the top end of the comb 10 can be more easily inserted into the bristles 242 and the impurities on the bristles 242 can be scraped off along the length direction of the bristles 242.
