Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, specifically to a sewage treatment device with multi-stage filtration function. Background Technology

[0002] During mechanical production, operations such as processing, cleaning, cooling, and lubrication generate a large amount of wastewater. If this wastewater is directly discharged into the environment, it will pollute water bodies and soil, affecting the environment and health. Moreover, wastewater may contain various impurities, necessitating treatment. Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. Wastewater treatment equipment is used in wastewater treatment. Existing wastewater treatment technologies typically use filters to remove impurities from the wastewater. However, when there are too many impurities in the wastewater, the filters are easily clogged. Therefore, it is necessary to frequently clean the accumulated impurities on the filters. During the cleaning process, the equipment needs to be repeatedly started and stopped, reducing the wastewater filtration speed, which not only reduces wastewater treatment efficiency but also increases operating costs.

[0003] Application number CN202220886009.7 discloses a wastewater treatment device with multi-stage filtration, including a treatment tank. The upper end of the treatment tank has an inlet, and a maintenance door is hinged to the front end. A sealing strip is fixedly installed at the rear end of the maintenance door. Support legs are fixedly installed on both the left and right sides of the lower end of the treatment tank. A drain pipe is inserted through the middle of the lower end of the treatment tank, communicating with the interior of the treatment tank. A water guide pipe is fixedly installed on the upper wall of the treatment tank, communicating with the interior of the inlet. Four positioning mechanisms are fixedly installed inside the treatment tank, and each of the four positioning mechanisms can be detachably installed with a filter mechanism for wastewater treatment. However, to avoid impurities in the wastewater clogging the filter mechanism, this wastewater treatment device requires frequent cleaning. This necessitates shutting down the wastewater treatment device each time the filter mechanism is disassembled, wasting time and affecting the working efficiency of the wastewater treatment device. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that sewage treatment devices need to frequently clean the impurities accumulated on the filter screen, and the equipment needs to be repeatedly started and stopped during the cleaning process, which reduces the speed of sewage filtration. Therefore, this invention proposes a sewage treatment device with multi-stage filtration function.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device with multi-stage filtration function, comprising a treatment tank; the treatment tank is a rectangular hollow box, with an inlet pipe connected to one side of the top surface and a drain pipe connected to one side of the bottom surface; support legs are evenly welded to the four corners of the lower surface of the treatment tank; a large-hole filter plate, a medium-hole filter plate, and a small-hole filter plate are installed sequentially from top to bottom on one side wall inside the treatment tank; three discharge troughs are symmetrically opened on the other side wall of the treatment tank; a collection box is sequentially connected to the outlet of each discharge trough; a cleaning component for cleaning the filter plates is also provided inside the treatment tank.

[0006] The cleaning component includes a tapping component installed inside the processing box and a driving component installed on the outer wall of the processing box. The driving component is used to drive the tapping component to work. The tapping component includes three rotating shafts that are symmetrically connected in sequence by bearings on the inner rear side wall of the processing box. Rubber strips are glued to the front side of the outer side wall of each rotating shaft. The rear end of each rotating shaft passes through the rear side wall of the processing box and is equipped with a driven bevel gear.

[0007] The driving component includes a support plate disposed on the upper part of the outer wall of the processing box; a motor is mounted on the lower surface of the support plate, and a rotating rod is connected to one end of the output shaft of the motor; a fixing plate is connected to the bottom of the rotating rod.

[0008] Three active bevel gears are arranged equidistantly on the rotating rod; the active bevel gears are meshed with the driven bevel gears.

[0009] The fixed end of the fixed plate is welded to the outer wall of the processing box, and the upper surface of the fixed plate is rotatably connected to the rotating rod through a bearing.

[0010] A cleaning groove is provided on one side wall of the collection box, and a baffle is slidably connected to the front surface of the collection box; a pull ring is installed on the front surface of the baffle.

[0011] The front side wall of the collection box is threaded with a top rod, and the end of the top rod is provided with a knob.

[0012] A switch button is installed in the middle of the rear surface of the processing box. The electrical output terminal of the switch button is electrically connected to the electrical input terminal of the motor through a wire, which facilitates the control of the motor's working status.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention enables multi-stage filtration by using filter plates of different specifications installed in the treatment tank, reducing the filtration pressure on a single filter plate. Furthermore, when used in conjunction with a cleaning component, each filter plate is tapped. Impurities on the filter plates are then rolled off the plates and into the collection box by the combined effects of gravity and the tapping and shaking of the rubber strips. This prevents impurities from accumulating on the filter plates, eliminating the need to stop the machine to disassemble and clean the filter plates. This maintains the continuity of wastewater filtration, saves time, improves wastewater treatment efficiency, reduces operating costs, and brings benefits to the enterprise.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1-6As shown, a wastewater treatment device with multi-stage filtration function includes a treatment tank 11. The treatment tank 11 is a rectangular hollow box. A water inlet pipe 12 is connected to one side of the top surface of the treatment tank, and a drain pipe 13 is connected to one side of the bottom surface of the treatment tank. Support legs 117 are evenly welded to the four corners of the lower surface of the treatment tank 11. A circular plate 118 is welded to the bottom end of the support leg 117. A rubber foot 119 is bonded to the lower surface of the circular plate 118. The support legs 117 and the circular plate 118 provide support for the treatment tank 11, and the rubber foot 119 increases the anti-slip performance of the circular plate 118.

[0025] The treatment tank 11 has three types of filter plates installed at an angle from top to bottom on one side wall: a large-pore filter plate 14, a medium-pore filter plate 15, and a small-pore filter plate 16. These three filter plates allow wastewater to be treated to be introduced into the treatment tank 11 through the inlet pipe 12. The large-pore filter plate 14, medium-pore filter plate 15, and small-pore filter plate 16 can filter impurities of different pore sizes in the wastewater, achieving multi-stage filtration and reducing the filtration pressure on a single filter plate. Impurities are filtered out and remain on the upper surface of each filter plate. The other side wall of the treatment tank 11 has three symmetrically arranged discharge troughs 17. Each discharge trough 17 has an outlet connected to a collection box 18. The treatment tank also includes a cleaning component for cleaning the filter plates.

[0026] The cleaning component includes a tapping component disposed inside the processing chamber and a driving component disposed on the outer wall of the processing chamber. The driving component is used to drive the tapping component to work. The tapping component includes three rotating shafts 19 disposed on the inner rear side wall of the processing chamber 11 and connected in sequence symmetrically by bearings. Rubber strips 110 are glued to the front side of the outer side wall of each rotating shaft 19. The rear end of each rotating shaft 19 passes through the rear side wall of the processing chamber 11 and is equipped with a driven bevel gear 111. The driving component includes a support plate 114 disposed on the upper part of the outer wall of the processing chamber 11. A motor 115 is mounted on the lower surface of the support plate 114, and a rotating rod 113 is connected to one end of the output shaft of the motor 115. The bottom of the rotating rod 113... A fixed plate 112 is connected; three active bevel gears 116 are arranged equidistantly on the rotating rod 113; the active bevel gears 116 are meshed with the driven bevel gears 111; the fixed end of the fixed plate 112 is welded to the outer wall of the processing box, and the upper surface of the fixed plate 112 is rotatably connected to the rotating rod 113 through a bearing; the motor 115 rotates to drive the rotating rod 113 and the active bevel gears 116 to rotate, which in turn drives the driven bevel gears 111, the rotating shaft 19 and the rubber strip 110 to rotate. The rotating rubber strip 110 repeatedly beats each filter plate, and the impurities on the filter plates will roll down along the filter plates and the discharge chute 17 into the collection box 18 under the combined action of gravity and the beating and shaking of the rubber strip 110.

[0027] A cleaning groove 120 is provided on one side wall of the collection box 18, and a baffle 121 is slidably connected to the front surface of the collection box 18. A pull ring 122 is installed on the front surface of the baffle 121. The pull ring 122 facilitates the movement of the baffle 121. When it is necessary to clean the impurities inside the collection box 18, the baffle 121 is pulled outward, and the impurities will be discharged along the cleaning groove 120. A push rod 123 is threadedly connected to the front side wall of the collection box 18, and a knob 124 is provided at the end of the push rod 123. Turning the knob 124 clockwise can make the push rod 123 press against the baffle 121 to lock the baffle 121 and prevent the baffle 121 from accidentally shifting. A switch button 125 is installed in the middle of the rear surface of the processing box 11. The electrical output terminal of the switch button 125 is electrically connected to the electrical input terminal of the motor 115 through a wire. This facilitates the control of the working state of the motor 115.

[0028] In practical use, the wastewater to be treated enters the treatment tank 11 through the inlet pipe 12. The large-pore filter plate 14, medium-pore filter plate 15, and small-pore filter plate 16 can filter impurities of different pore sizes in the wastewater, realizing multi-stage filtration and reducing the filtration pressure of a single filter plate. After the impurities are filtered out, they remain on the upper surface of each filter plate. The motor 115 rotates, driving the rotating rod 113 and the driving bevel gear 116 to rotate, which in turn drives the driven bevel gear 111, the rotating shaft 19, and the rubber strip 110 to rotate. The rotating rubber strip 110 repeatedly beats each filter plate. Under the combined action of gravity and the beating and shaking of the rubber strip 110, the impurities on the filter plates will roll down along the filter plates and the discharge chute 17 into the collection box 18, which can prevent impurities from accumulating on the filter plates. There is no need to stop the machine to disassemble the filter plates for cleaning, maintaining the continuity of wastewater filtration and treatment, saving time and improving the efficiency of wastewater treatment.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
