Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a uniformly filtered, anti-clogging wastewater treatment device. Background Technology

[0002] Wastewater refers to the total amount of water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other non-useful water such as initial rainwater runoff into drainage pipes and ditches. Generally, it refers to water that cannot be recycled after certain technical treatment or water that cannot be purified to meet certain standards after primary pollution. Direct discharge or infiltration of wastewater may pollute surface water and groundwater, damage aquatic ecosystems, affect the survival and reproduction of aquatic organisms, and may also cause soil pollution, affecting the growth of plants and soil microorganisms. In order to solve the environmental damage caused by wastewater, wastewater treatment equipment has become increasingly popular in recent years. Wastewater treatment equipment uses physical, chemical and biological methods to treat wastewater, purify it, reduce pollution, and even achieve wastewater recycling and reuse, making full use of water resources.

[0003] In the physical filtration stage of current wastewater treatment equipment, existing filtration methods often rely on filter screens. However, this traditional filtration mode has significant drawbacks: firstly, the filtration area of ​​the filter screen is limited, resulting in a limited processing capacity per unit time, making it difficult to adapt to the needs of high-flow-rate wastewater treatment; secondly, suspended particles and impurities in the wastewater easily adhere to the surface of the filter screen, causing rapid clogging. This not only further reduces the effective filtration area and significantly lowers the filtration area utilization efficiency, but also requires frequent shutdowns for cleaning or replacement of the filter screen, increasing maintenance costs and seriously affecting the overall filtration effect and the continuity of the wastewater treatment process. Therefore, this invention provides a uniform filtration anti-clogging wastewater treatment device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a uniformly filtered, anti-clogging wastewater treatment device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a uniformly filtered, anti-clogging wastewater treatment device, comprising a housing, wherein a uniformly filtered component is provided inside the housing for filtering wastewater, and a cleaning component is provided on one side of the outer wall of the uniformly filtered component;

[0006] The uniform filtration assembly includes a filter cylinder, a rotating shaft fixedly installed at the top of the filter cylinder, a rotating gear fixedly installed at the top of the rotating shaft, an incomplete gear meshing on one side of the outer wall of the rotating gear, a rotating tube rotatably installed on one side of the outer wall of the housing, and a rotary joint fixedly installed at one end of the outer wall of the rotating tube.

[0007] The cleaning assembly includes a second rotating rod, and a cleaning scraper is fixedly installed on one side of the outer wall of the second rotating rod for cleaning the surface of the filter cartridge.

[0008] Preferably, the rotating shaft is rotatably mounted on the top of the housing, a mounting bracket is fixedly mounted on the top of the housing, a motor is fixedly mounted on the top of the mounting bracket, and the output end of the motor passes through the inner wall of the mounting bracket and is fixedly connected to an incomplete gear.

[0009] Preferably, a vertical plate is fixedly installed at the top of the box, a first rotating rod is rotatably installed on the outer wall of the vertical plate, a second bevel gear is fixedly installed at one end of the outer wall of the first rotating rod, a first bevel gear is meshed on one side of the outer wall of the second bevel gear, and the first bevel gear is fixedly connected to the incomplete gear.

[0010] Preferably, a second pulley is fixedly installed on the outer wall of the rotating tube, and a first pulley is fixedly installed on the other end of the outer wall of the first rotating rod. A belt is sleeved on the outer walls of the first pulley and the second pulley.

[0011] Preferably, a drain pipe is rotatably installed on the inner wall of the filter cartridge, one end of the drain pipe penetrates one side of the outer wall of the housing, the second rotating rod is rotatably installed on the top of the housing, a fixing frame is fixedly installed on the top of the housing, and a worm gear is rotatably installed on the inner wall of the fixing frame.

[0012] Preferably, a worm wheel is engaged on one side of the outer wall of the worm, and one side of the outer wall of the worm wheel is fixedly connected to the top end of the second rotating rod. One end of the outer wall of the worm passes through the outer wall of the fixed frame and is fixedly mounted with a rocker arm for driving the worm to rotate. Brackets are fixedly mounted on both sides of the outer wall of the housing for supporting the housing.

[0013] Beneficial effects

[0014] This invention provides a uniformly filtered, anti-clogging wastewater treatment device. Compared with the prior art, it has the following advantages:

[0015] (1) The uniform filtration anti-clogging wastewater treatment equipment, through the linkage design of the uniform filtration components, on the one hand, utilizes the meshing of the incomplete gear and the rotating gear to enable the filter cylinder to rotate intermittently, so that each area of ​​the outer wall of the filter cylinder is in uniform contact with the wastewater, avoiding the problem of "local overload and other areas being idle" of the traditional fixed filter screen, and improving the utilization rate of the filtration area; on the other hand, the rotating pipe rotates synchronously with the filter cylinder to achieve uniform water distribution, so that the wastewater entering the box can be evenly sprayed onto the outer wall of the filter cylinder for filtration, further ensuring the uniformity of contact between the wastewater and the filter cylinder.

[0016] (2) In this uniformly filtered, anti-clogging wastewater treatment equipment, the cleaning component achieves controllable adjustment of the "contact-disengagement" between the scraper and the filter cartridge through the transmission cooperation of a rocker arm, worm gear, and worm wheel: only when cleaning is needed, the rocker arm is rotated to make the scraper adhere to the surface of the filter cartridge, and the intermittent rotation of the filter cartridge is used to scrape off the pollutants; when cleaning is not needed, the rocker arm is rotated in the opposite direction to move the scraper to one side of the housing, completely disengaging it from the filter cartridge. This design fundamentally avoids the problem of "continuous friction between the scraper and the filter element" in traditional cleaning structures, eliminating ineffective wear during non-cleaning periods.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides two technical solutions:

[0026] Figures 1-6 The first embodiment is shown: a uniformly filtered anti-clogging wastewater treatment device, including a housing 1, a uniformly filtered component 2 is provided inside the housing 1 for filtering wastewater, and a cleaning component 3 is provided on one side of the outer wall of the uniformly filtered component 2.

[0027] The uniform filtration assembly 2 includes a filter cylinder 21. The outer wall of the filter cylinder 21 can filter large particulate pollutants. Then, an activated carbon process layer or a more refined filtration assembly can be set inside to further filter the wastewater. A rotating shaft 22 is fixedly installed at the top of the filter cylinder 21. A rotating gear 23 is fixedly installed at the top of the rotating shaft 22. An incomplete gear 26 is meshed on one side of the outer wall of the rotating gear 23. A rotating pipe 214 is rotatably installed on one side of the outer wall of the housing 1. A rotary joint 215 is fixedly installed at one end of the outer wall of the rotating pipe 214. The rotary joint 215 is existing technology and can continuously pass wastewater into the rotating pipe 214 during the rotation of the rotating pipe 214.

[0028] The cleaning assembly 3 includes a second rotating rod 32, and a cleaning scraper 33 is fixedly installed on one side of the outer wall of the second rotating rod 32 for cleaning the surface of the filter cartridge 21.

[0029] The rotating shaft 22 is rotatably mounted on the top of the housing 1. A mounting bracket 24 is fixedly mounted on the top of the housing 1. A motor 25 is fixedly mounted on the top of the mounting bracket 24. The output end of the motor 25 passes through the inner wall of the mounting bracket 24 and is fixedly connected to the incomplete gear 26.

[0030] A vertical plate 29 is fixedly installed on the top of the housing 1. A first rotating rod 210 is rotatably installed on the outer wall of the vertical plate 29. A second bevel gear 28 is fixedly installed on one end of the outer wall of the first rotating rod 210. A first bevel gear 27 is meshed on one side of the outer wall of the second bevel gear 28. The first bevel gear 27 is fixedly connected to the incomplete gear 26. When the incomplete gear 26 rotates, it can drive the first bevel gear 27 to rotate together.

[0031] Figures 1-6 The second embodiment is shown. The main difference from the first embodiment is that a second pulley 213 is fixedly installed on the outer wall of the rotating tube 214, and a first pulley 211 is fixedly installed on the other end of the outer wall of the first rotating rod 210. A belt 212 is sleeved on the outer wall of the first pulley 211 and the second pulley 213. Under the action of the first pulley 211, the second pulley 213 and the belt 212, the rotating tube 214 can be driven to rotate, so that the wastewater discharged from the rotating tube 214 can be evenly distributed on the outer wall of the filter cylinder 21.

[0032] A drain pipe 216 is rotatably installed on the inner wall of the filter cartridge 21. One end of the drain pipe 216 penetrates one side of the outer wall of the box 1. The wastewater filtered in the filter cartridge 21 can be discharged out of the box 1 through the drain pipe 216. The second rotating rod 32 is rotatably installed on the top of the box 1. A fixing frame 31 is fixedly installed on the top of the box 1. A worm gear 34 is rotatably installed on the inner wall of the fixing frame 31.

[0033] A worm wheel 35 is engaged on one side of the outer wall of the worm 34. The worm wheel 35 and the worm 34 are self-locking. One side of the outer wall of the worm wheel 35 is fixedly connected to the top of the second rotating rod 32. One end of the outer wall of the worm 34 passes through the outer wall of the fixed frame 31 and is fixedly installed with a rocker arm 36 for driving the worm 34 to rotate. Brackets 4 are fixedly installed on both sides of the outer wall of the housing 1 for supporting the housing 1.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, the wastewater to be treated is first connected to the rotary joint 215 on the outer wall of the tank 1 through an external pipeline. The wastewater enters the rotary pipe 214 fixed to it through the rotary joint 215, completing the transportation into the tank 1. Then, the motor 25 on the mounting frame 24 is started. The output end of the motor 25 drives the incomplete gear 26 to rotate. The incomplete gear 26 simultaneously drives the first bevel gear 27 fixed to it to rotate. The first bevel gear 27 meshes with the second bevel gear 28 on the vertical plate 29, driving the first rotating rod 210 to rotate. The other end of the first rotating rod 210... The first pulley 211 drives the second pulley 213 and the rotating tube 214 to rotate synchronously via the belt 212. When the rotating tube 214 rotates, it sprays the internal wastewater evenly onto the outer wall of the filter cylinder 21 inside the housing 1. On the other hand, the incomplete gear 26 meshes with the rotating gear 23 at the top of the rotating shaft 22. When the toothed area of ​​the incomplete gear 26 contacts the rotating gear 23, it drives the rotating shaft 22 to rotate around the top of the housing 1, causing the bottom filter cylinder 21 to rotate intermittently inside the housing 1. When the toothless area contacts the filter cylinder 21, the filter cylinder 21 briefly stops rotating, thus balancing energy consumption and efficiency.

[0036] Wastewater permeates the filter holes of filter cylinder 21 under external pressure, and suspended impurities are trapped on the outer wall of filter cylinder 21. The purified water enters the internal cavity of filter cylinder 21. One end of the drain pipe 216 fixed on the inner wall of filter cylinder 21 passes through the outside of the box body 1 and remains fixed. Filter cylinder 21 rotates around drain pipe 216. A seal is provided between the two to prevent leakage. After the clean water continuously flows into drain pipe 216, it is discharged out of box body 1 and finally transported to the reuse system or discharge pipeline.

[0037] When a decrease in the outflow of water from the drain pipe 216 is observed, and it is determined that impurities have accumulated on the outer wall of the filter cylinder 21 and need cleaning, the operator rotates the rocker arm 36 on the fixed frame 31 clockwise, causing the worm gear 34 to rotate around the inner wall of the fixed frame 31. The worm gear 34 meshes with the worm wheel 35 to drive the second rotating rod 32 to rotate, so that the cleaning scraper 33 on the outer wall of the second rotating rod 32 adheres to the outer wall of the filter cylinder 21. Relying on the intermittent rotation of the filter cylinder 21, the cleaning scraper 33 generates relative friction with the surface of the filter cylinder 21, scraping off the pollutants. The impurities fall to the bottom of the box 1 under the action of gravity. The bottom of the box 1 is equipped with an inclined structure or a slag collection trough to facilitate the collection of impurities. After the impurities accumulate to a certain amount, the pre-set drain valve at the bottom of the box 1 is opened, and the impurities are discharged from the drain valve with a small amount of flushing water or by gravity. Subsequent centralized treatment avoids secondary pollution.

[0038] After cleaning, turn the rocker arm 36 counterclockwise. Through the reverse transmission of the worm gear 34 and worm wheel 35, the cleaning scraper 33 is driven away from the filter cartridge 21 and stays on one side of the housing 1. The self-locking characteristics of the worm gear 34 and worm wheel 35 keep the cleaning scraper 33 in a stable position and avoid wear during non-cleaning periods. Throughout the process, the motor 25 continuously drives the uniform filter assembly 2. Wastewater continuously enters, clean water continuously exits through the drain pipe 216, and impurities are cleaned as needed through the drain valve, realizing continuous wastewater treatment until all filtration tasks are completed.
