Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an integrated sewage treatment device. Background Technique

[0002] Sewage treatment plants usually use filter plates to filter impurities in sewage. Since the filter plates in the prior art are usually flat, impurities will accumulate on the surface of the filter plates, resulting in the pores of the filter plates being easily blocked, which has certain drawbacks.

[0003] An integrated sewage treatment device proposed in Patent CN218871435U, through the cooperation between a water storage box, a drainage cylinder, filter holes, a cleaning mechanism and a lifting mechanism, when sewage enters the treatment tank, it will enter the water storage box. The sewage is filtered through the filter holes of the drainage cylinder and then discharged. When the filter holes are blocked, the water in the water storage box will accumulate. The gravity of the water compresses the lifting mechanism, causing the water storage box to move downward to expose new filter holes. At this time, the sewage can be filtered through the filter holes and discharged. Until the water storage box moves downward to the limit position, at this time all the filter holes are blocked, and then the cleaning mechanism is controlled to move up and down to clean the filter holes near the upper side of the drainage cylinder. At this time, the accumulated water is quickly discharged, and the water storage box at the bottom moves upward under the action of the lifting mechanism. When the water storage box moves upward, it can clean the filter holes near the lower side of the drainage cylinder, so that the water storage box can move downward slowly again to expose new filter holes for drainage, making the device not easy to be blocked and easy to clean, and it can be used for a long time without frequent cleaning, solving the problems that the filter plates in the prior art sewage treatment are not only easy to be blocked, affecting the speed of sewage treatment, but also the filter plates are relatively troublesome to clean, and the filter plates need to be frequently cleaned during the sewage treatment process, resulting in time-consuming and laborious and affecting the sewage treatment efficiency.

[0004] The problems existing in the above solution are: impurities of different sizes cannot be classified and cleaned, and then the filter holes with the same aperture are likely to affect the efficiency of wastewater passing through. At the same time, the filtered impurities cannot be well distinguished, and the recyclable materials need to be secondarily screened, which is rather inconvenient. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide an integrated sewage treatment device to solve the problems raised in the above background technique. The structure of the present utility model is novel. Different sizes of impurities in the wastewater are separated and filtered through the filter grooves of different sizes of three conical filter plates. And through the inclined surfaces of the conical filter plates, the impurities will not congest in one place, avoiding affecting the efficiency of wastewater passing through. Through the driving component, the three conical filter plates can be folded, so as to push the impurities on the inclined surfaces of the conical filter plates outwards to the outer ring, which is convenient for people to clean the impurities on the conical filter plates.

[0006] To achieve the above object, the present utility model is realized through the following technical solutions: An integrated sewage treatment device includes a sewage treatment tank. A upper pipe is fixed at the top inlet end of the sewage treatment tank, and a water inlet pipe is fixed at the top of the upper pipe. A filter plate assembly is arranged inside the upper pipe. The filter plate assembly includes three conical filter plates, and filter grooves of different sizes are formed on the surfaces of the conical filter plates. The inner diameter of the conical filter plates gradually decreases from top to bottom. A fixed shaft is fixed inside the water inlet pipe. A driving assembly is arranged at the bottom of the water inlet pipe inside the upper pipe. The driving assembly includes an outer sleeve. The outer sleeve slides along the surface of the fixed shaft, and the conical filter plates are slidably sleeved on the surface of the outer sleeve. An outer ring is fixed to the periphery of the outer sleeve, and the outer rings of the three conical filter plates are all fixed to the inner wall of the upper pipe.

[0007] Further, the top of the conical filter plate is a conical surface, and the bottom of the conical filter plate is hollowed out to allow the next conical filter plate to enter.

[0008] Further, the driving assembly further includes a first telescopic plate. A first telescopic plate is fixed to the inner wall of the outer ring at the top of each conical filter plate, and a second telescopic plate is arranged on one side of the first telescopic plate. Sliders are fixed to the extended ends of the first telescopic plate and the second telescopic plate, and the sliders can slide along the conical surface of the conical filter plate.

[0009] Further, an electric push rod is rotatably installed on the surface of the outer sleeve at the top of each conical filter plate through a bearing ring, and the extended end of the electric push rod is fixed to the conical filter plate.

[0010] Further, a connecting rod is fixed to the top of the retracted end of the second telescopic plate, and the other end of the connecting rod is fixed to the outer sleeve. The triangular space formed by the connecting rod, the outer sleeve and the second telescopic plate allows the electric push rod to rotate.

[0011] Further, a toothed ring is rotatably installed on the outer ring surface at the bottom of the water inlet pipe through a bearing, and a gear is meshed and connected to one side of the toothed ring. A motor is fixed to the outer ring surface at the bottom of the water inlet pipe corresponding to the position of the gear, and the output end of the motor is fixed to the gear. The toothed ring is fixedly connected to the retracted end of the topmost second telescopic plate.

[0012] Further, an elastic membrane is arranged between the first telescopic plate and the second telescopic plate.

[0013] Further, a side door is arranged on the side of the upper pipe, and impurities accumulated on the outer ring can be sent out through the side door.

[0015] The utility model is provided with a side door, which facilitates manual cleaning and discharging of impurities on the outer rings of the three groups of conical filter plates after opening.

[0016] During the ascending process of the superimposed conical filter plates of the utility model, the first telescopic plate and the second telescopic plate are squeezed and telescoped by the sliding of the slider along the conical surface, driving the elastic membrane to contract and slide along the conical surface of the conical filter plate, pushing the impurities onto the outer ring, which is equivalent to scraping the conical surface of the conical filter plate.

[0017] The utility model adjusts the distance between the three groups of conical filter plates through an electric push rod, which facilitates the superimposed cleaning of impurities on the conical surfaces of the conical filter plates. At the same time, the rotation of the outer sleeve will not affect the position of the electric push rod.

[0018] Compared with the prior art, the utility model separates and filters impurities of different sizes in the wastewater through the filter grooves of different sizes of the three groups of conical filter plates. And through the inclined surface of the conical filter plate, the impurities will not be congested in one place, avoiding affecting the efficiency of wastewater passing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0025] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: an integrated sewage treatment device, including a sewage treatment tank 1, a top inlet end of the sewage treatment tank 1 is fixed with an upper pipe 2, and a water inlet pipe 22 is fixed to the top of the upper pipe 2. A filter plate assembly 3 is arranged inside the upper pipe 2. The filter plate assembly 3 includes three conical filter plates 31, and filter grooves of different sizes are formed on the surfaces of the conical filter plates 31. The inner diameter of the conical filter plates 31 gradually decreases from top to bottom. A fixed shaft 23 is fixed inside the water inlet pipe 22. A driving assembly 4 is arranged at the bottom of the water inlet pipe 22 inside the upper pipe 2. The driving assembly 4 includes an outer sleeve 47. The outer sleeve 47 slides along the surface of the fixed shaft 23, and the conical filter plates 31 are slidably sleeved on the surface of the outer sleeve 47. An outer ring 32 is fixed to the periphery of the outer sleeve 47. The outer rings 32 of the three conical filter plates 31 are all fixed to the inner wall of the upper pipe 2. In the solution, the principle of the sewage treatment tank 1 is the same as that of the integrated sewage treatment equipment. When using the device, wastewater is sent in from the water inlet pipe 22, and after being filtered by the three conical filter plates 31 for impurities of different sizes, it is sent into the sewage treatment tank 1 for the next stage of treatment. The three conical filter plates 31 are stacked through the driving assembly 4, and the impurities on the conical surface are cleaned and pushed onto the outer ring 32 to prevent the conical filter plates 31 from being blocked and facilitate manual cleaning.

[0026] In this embodiment, the top of the conical filter plate 31 is a conical surface, and the bottom of the conical filter plate 31 is hollowed out to allow the next conical filter plate 31 to enter. The driving assembly 4 further includes a first telescopic plate 44. A first telescopic plate 44 is fixed to the inner wall of the outer ring 32 at the top of each conical filter plate 31. A second telescopic plate 45 is arranged on one side of the first telescopic plate 44. Sliders 410 are fixed to the extended ends of the first telescopic plate 44 and the second telescopic plate 45. The sliders 410 can slide along the conical surface of the conical filter plate 31. Electric push rods 48 are rotatably installed on the surface of the outer sleeve 47 at the top of each conical filter plate 31 through bearing rings, and the extended ends of the electric push rods 48 are fixed to the conical filter plates 31. By adjusting the distance between the three conical filter plates 31 through the electric push rods 48, it is convenient to stack and clean the impurities on the conical surface of the conical filter plates 31. At the same time, the rotation of the outer sleeve 47 will not affect the position of the electric push rods 48.

[0027] In this embodiment, a connecting rod 46 is fixed to the top of the receiving end of the second telescopic plate 45, and the other end of the connecting rod 46 is fixed to the outer sleeve 47. The triangular space formed by the connecting rod 46, the outer sleeve 47 and the second telescopic plate 45 allows the electric push rod 48 to rotate. A toothed ring 43 is rotatably mounted on the surface of the outer ring 32 at the bottom of the water inlet pipe 22 through a bearing, and a gear 42 is meshed and connected to one side of the toothed ring 43. A motor 41 is fixed to the surface of the outer ring 32 at the bottom of the water inlet pipe 22 corresponding to the position of the gear 42, and the output end of the motor 41 is fixed to the gear 42. The toothed ring 43 is fixedly connected to the receiving end of the topmost second telescopic plate 45. An elastic film 49 is arranged between the first telescopic plate 44 and the second telescopic plate 45. The motor 41 drives the gear 42 to rotate and mesh with the toothed ring 43. Through the connection of the outer sleeve 47, the three groups of second telescopic plates 45 and the connecting rod 46 rotate synchronously, and the elastic film 49 between them and the first telescopic plate 44 is unfolded. (Here, the elastic film 49 can be stored on both sides of the first telescopic plate 44 and the second telescopic plate 45, and the outer side of the elastic film 49 slides along the inner wall of the outer ring 32. A clamping groove for clamping the elastic film 49 is arranged on the inner side of the outer ring 32, which is not shown in the figure, so as to facilitate the elastic film 49 to wrap the entire conical surface after unfolding). During the process of the conical filter plate 31 stacking and rising, the first telescopic plate 44 and the second telescopic plate 45 are squeezed and stretched by the slider 410 sliding along the conical surface. (Both the first telescopic plate 44 and the second telescopic plate 45 are provided with springs inside, which can automatically reset to the original length), driving the elastic film 49 to contract and slide along the conical surface of the conical filter plate 31, pushing the impurities onto the outer ring 32, which is equivalent to scraping the wall of the conical surface of the conical filter plate 31.

[0028] In this embodiment, a side door 21 is arranged on the side of the upper pipe 2, and the impurities accumulated on the outer ring 32 can be sent out through the side door 21. Through the arrangement of the side door 21, it is convenient for people to clean and send out the impurities on the outer ring 32 of the three groups of conical filter plates 31 after opening.

[0029] When using the device, the wastewater is sent in from the water inlet pipe 22, and after being filtered by the three groups of conical filter plates 31 for impurities of different sizes, it is sent into the sewage treatment tank 1 for the next stage of treatment. The motor 41 drives the gear 42 to rotate and mesh with the toothed ring 43. Through the connection of the outer sleeve 47, the three groups of second telescopic plates 45 and the connecting rod 46 rotate synchronously, and the elastic film 49 between them and the first telescopic plate 44 is unfolded. During the process of the conical filter plate 31 stacking and rising, the first telescopic plate 44 and the second telescopic plate 45 are squeezed and stretched by the slider 410 sliding along the conical surface, driving the elastic film 49 to contract and slide along the conical surface of the conical filter plate 31, pushing the impurities onto the outer ring 32, which is equivalent to scraping the wall of the conical surface of the conical filter plate 31, avoiding the blockage of the conical filter plate 31 and facilitating manual cleaning.
