[0002] The fixed sand filter tank flusher is a device used in water treatment equipment, mainly used in sand filter tanks for oilfield oily wastewater treatment and filtration. Its working principle is to use quartz sand as the filter medium, pressurize it through a water pump, and when the sewage passes through the sand filter bed, the dirt in the water is adsorbed and intercepted by the sand filter bed, and then backwash it with clean water regularly to remove the intercepted adsorbent.

[0003] Chinese patent document CN2815466Y discloses a sand filter. It is a sub-filter tank combination filter tank, each of which has a sand filter bed and a support layer. The high inlet and the low outlet are respectively connected to the corresponding manifolds for filtering processes, which can be combined and decomposed at will. The traditional fixed backwashing is replaced by a movable forward backwashing. The flushing process and the filtering process are separated from each other. At the same time, there is a set of movable flushing devices. The flushing liquid enters the sub-filter tank through the flushing pipe and is sprayed out from the combined nozzle and hydraulic oscillator of the flusher. Driven by the lifting mechanism, the flusher moves up and down in the sand filter bed. Under the action of the hydraulic force, the sand filter material is all in a suspended boiling state. Under the action of the wave field of the hydraulic oscillator, it can accelerate the thorough desorption effect and regenerate the sand filter material.

[0004] The existing technology has the following problems:

[0005] Although the sand filter uses two sub-filter tanks to form a backwashable structure, allowing the internal sand filter bed to be used for a long time, the sand filter needs maintenance. After long-term non-use, bacteria are easily bred inside, and the internal sand and gravel need to be cleaned out. However, the lower side of the sub-filter tank of the sand filter is in a closed state, making it difficult to clean and maintain. Utility Model Content

[0024] like Figure 1 , Figure 2 As shown, a fixed sand filter tank flusher comprises a sand filter tank body 1, wherein two sand filter tank bodies 1 are symmetrically distributed on the left and right, a support frame 2 is fixedly connected to the outer walls of the two sand filter tank bodies 1 near the bottom, a bottom support mechanism 3 is movably sleeved on the lower sides of the two sand filter tank bodies 1, an adjustment mechanism 4 is fixedly connected to the inner sides of the two sand filter tank bodies 1, a water control valve 5 is fixedly connected to the middle part of the upper wall of the two sand filter tank bodies 1, a first water pipe 6 is fixedly connected to the upper side of the water control valve 5, a second water pipe 7 is fixedly connected to the side of the water control valve 5, and a third water pipe 8 is fixedly connected to the lower side of the bottom support mechanism 3 through a hose.

[0025] It should be noted that the two sand filter tank bodies 1 can form a backwashing structure by relying on the first water pipe 6, the second water pipe 7 and the third water pipe 8, so that the sand and gravel inside the sand filter tank body 1 can be used for as long as possible and reduce maintenance work.

[0026] like Figure 2 , Figure 3As shown, the bottom support mechanism 3 includes a support plate 31, and a plurality of annular distribution sleeves 32 are movably sleeved on the outer side of the support plate 31, and the lower flange of the sand filter tank body 1 is movably sleeved on the inner side of the sleeve 32, and a plurality of screws are fixedly connected between the upper and lower walls of the plurality of sleeves 32.

[0027] It should be noted that the sleeve 32 is used to connect the support plate 31 and the sand filter tank body 1, the screws fix the support plate 31 on the sand filter tank body 1, the lifting device is placed on the lower side of the support plate 31, and then the screws and the sleeve 32 are removed. The lifting device drives the support plate 31 to move slowly downward, so that the sand and gravel inside the sand filter tank body 1 are released.

[0028] like Figure 4 As shown, a slot 33 is provided on the upper side of the support plate 31 near the edge, the convex ring on the lower surface of the sand filter tank body 1 is movably sleeved on the inner side of the slot 33, and a rubber ring 34 is fixedly connected to the inner lower surface of the slot 33.

[0029] It should be noted that the convex ring on the lower side of the sand filter tank body 1 is sleeved into the inner side of the card slot 33 and is sealed with a rubber ring 34, so that the gap between the support plate 31 and the sand filter tank body 1 is closed to prevent water from overflowing therefrom.

[0030] like Figure 3 As shown, the upper surface of the support plate 31 is in a spherical shape that protrudes upward.

[0031] It should be noted that the shape of the support plate 31 allows the sand and gravel on the support plate 31 to quickly slide to the surroundings when the support plate 31 is removed, thereby preventing the sand and gravel from accumulating on the support plate 31 .

[0032] like Figure 4 As shown, a water-permeable plate 35 is fixedly sleeved on the middle part of the upper surface of the support plate 31, and the third water pipe 8 and the lower axis of the support plate 31 are connected through a hose.

[0033] It should be noted that the water-permeable plate 35 is used to isolate the third water pipe 8 from the sand and gravel on the upper side to prevent the sand and gravel from falling into the inner side of the third water pipe 8. A water-permeable hole is provided on the upper side of the support plate 31 near the edge, and the water in the surrounding area can enter the inner side of the third water pipe 8 through the water-permeable hole.

The water distributor 41 evenly spreads the water introduced by the water control valve 5 on every part of the internal sand and gravel, and the water retaining plate 42 is used to block the water that seeps into the sand and gravel, so as to extend the time of water in the sand and gravel as much as possible and improve the filtering effect.

[0036] The working principle of the utility model is as follows: first, the clamping sleeve 32 is used to connect the support plate 31 and the sand filter tank body 1, and the screws fix the support plate 31 on the sand filter tank body 1, and the lifting device is placed on the lower side of the support plate 31, and then the screws and the clamping sleeve 32 are removed, and the lifting device drives the support plate 31 to move down slowly, so that the sand and gravel inside the sand filter tank body 1 are released. The shape of the support plate 31 is such that when the support plate 31 is removed, the sand and gravel on the support plate 31 can quickly slide to the surroundings to avoid the accumulation of sand and gravel on the support plate 31. By using the clamping sleeve 32 and screws to fix the support plate 31 and the sand filter tank body 1 together, the clamping sleeve 32 is convenient to be removed from the sand filter tank body 1, so that the lower side of the sand filter tank body 1 is in an open state, and the sand and gravel inside the sand filter tank body 1 is easy to be released. It is convenient for the maintenance of the flusher. Finally, the water distributor 41 is a device for evenly distributing water. It is widely used in water treatment, cooling systems and other fields. Its main function is to evenly distribute liquid or gas to a designated area to improve the operating efficiency and treatment effect of the equipment. The water distributor 41 evenly spreads the water introduced by the water control valve 5 on every part of the internal sand and gravel. The water baffle 42 is used to block the water that seeps into the sand and gravel, so as to extend the time of water in the sand and gravel as much as possible and improve the filtering effect. The water introduced by the water control valve 5 is evenly spread on the sand and gravel inside the sand filter tank body 1 through the water distributor 41, so that every part of the sand and gravel inside the sand filter tank body 1 can play a filtering operation, avoiding the problem of direct introduction resulting in only the sand and gravel in the middle being filtered.
