Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment tank for wastewater treatment. Background Technology

[0002] The function of a wastewater treatment tank is generally to collect wastewater and perform preliminary filtration. After filtration, the wastewater enters the anaerobic tank, and the anaerobic wastewater enters the aerobic tank. After being treated in the aerobic tank, it enters the sedimentation tank for sedimentation and separation, thus completing the entire wastewater treatment process.

[0003] The current wastewater treatment tank filters wastewater in the following ways: First, preliminary filtration uses a screen and filter mesh to filter out large debris, removing larger solid particles, floating objects, and large impurities such as plastic bags and paper. Then, intermediate filtration uses a carbon filter to remove organic matter and residual chlorine. Generally, wastewater is treated by the wastewater treatment tank, but the treatment level is not very high, so it ends here and there is no subsequent deep filtration.

[0004] However, during the initial filtration process of current wastewater treatment tanks, a lot of garbage accumulates on the screens and filters. Current treatment tanks cannot clean this up quickly and automatically, and are prone to clogging. In particular, the filters are extremely prone to clogging for small impurities, making them difficult to clean and causing a significant drop in wastewater throughput. If small impurities are not filtered, the wastewater will be subject to increased wear and tear on the filter media when it enters the intermediate filtration stage. Therefore, we propose a wastewater treatment tank for wastewater treatment. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology. By dividing the primary filtration function, the initial filtration pressure is reduced, and larger solid particles, floating objects, and large impurities such as plastic bags and paper in the sewage are automatically removed from the screen and filter screen. At the same time, the downstream micro-impurity filter screen is automatically cleaned to avoid the filter screen being blocked by micro-impurities.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wastewater treatment tank for wastewater treatment includes a wastewater treatment tank, wherein the wastewater treatment tank is divided into two spaces by a partition, one side being a filtration chamber that is wider at the top and narrower at the bottom, and the other side being a cleaning chamber that is narrower at the top and wider at the bottom.

[0008] The interior of the filter chamber is provided with a multi-stage filter screen, a micro impurity filter screen and a medium-level filter layer from top to bottom. A cleaning component is provided on one side of the multi-stage filter screen, and a drive chamber is installed on one side of the micro impurity filter screen. The micro impurity filter screen is provided with a telescopic rotation mechanism on the drive chamber side.

[0009] The cleaning chamber is equipped with a baffle plate corresponding to the multi-stage filter screen. The baffle plate is pushed by a first push rod installed on the outside of the cleaning chamber. The extension and retraction of the first push rod causes the baffle plate to move closer to / away from the baffle plate. The cleaning chamber is equipped with a high-pressure flushing gun head corresponding to the micro-impurity filter screen.

[0010] A drain window is provided on the partition between the multi-stage filter screen and the partition, and a pass-through window is provided on the partition between the micro impurity filter screen and the high-pressure flushing gun head.

[0011] Furthermore, a sewage inlet pipe is installed at the top of the sewage treatment tank, and the sewage inlet pipe is connected to the filter chamber;

[0012] The front of the filter chamber is provided with a drain pipe located below the medium filtration layer;

[0013] The cleaning chamber is located away from the filtration chamber and near the bottom, where a waste discharge guide hopper is provided.

[0014] Furthermore, the multi-stage filter screen has no fewer than three layers, with the mesh size increasing from top to bottom.

[0015] Furthermore, a rotating disk is installed on the side of the micro impurity filter screen near the telescopic rotating mechanism, and the mesh number of the micro impurity filter screen is greater than the mesh number of the adjacent multi-stage filter screen.

[0016] Furthermore, the medium-strength filtration layer is selected from one or both of carbon filtration and sand filtration.

[0017] Furthermore, the cleaning assembly includes a push bucket, a second cylinder, and a scraper pad. The push bucket is parallel to the sewage discharge window. The second cylinder is installed on the outer output end of the sewage treatment tank to fix the push bucket. The scraper pad is installed at the bottom of the push bucket to adhere to the multi-stage filter screen.

[0018] Furthermore, the telescopic rotation mechanism includes a motor, a third cylinder, and a sliding assembly. The output end of the motor extends to a fixed rotating disk inside the filter chamber. The third cylinder is installed on the outside of the sewage treatment tank, with its output end fixing the motor housing. The fixed motor housing is slidably connected to the sliding assembly inside the drive chamber. The sliding assembly is selected as a slider guide rail assembly or a slider rod assembly.

[0019] Furthermore, the first push rod pushes the barrier plate to the partition plate where a barrier plate locking groove is provided, and the edge of the barrier plate locking groove is provided with a waterproof pad.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By designing the filter chamber with a combination of multi-stage filter screens, micro impurity filter screens and medium-density filter layers, graded filtration of wastewater is achieved. This design not only improves filtration efficiency but also ensures that impurities of different sizes can be effectively removed, thereby improving the water purification effect.

[0022] 2. This utility model introduces a cleaning component and a telescopic rotation mechanism, which realizes the automated cleaning of multi-stage filter screens and micro impurity filter screens. This not only avoids the problem of filter screen clogging, but also reduces the frequency and difficulty of manual cleaning, and improves the operational stability and maintenance convenience of the equipment.

[0023] 3. Due to the multi-stage filtration system and micro-debris filter, both large and small impurities can be effectively removed before entering the intermediate filtration layer. This not only protects the filter media of the intermediate filtration layer from excessive load, but also extends the service life of the filter media and reduces operating costs.

[0024] 4. The wastewater treatment tank is separated into a filtration chamber and a cleaning chamber by a partition. This design ensures that the filtration and cleaning processes do not interfere with each other, thus improving the overall operating efficiency of the equipment. Attached Figure Description

[0037] Example 1

[0038] like Figure 1-4 As shown, this utility model provides a technical solution: a sewage treatment tank for sewage treatment, the structural features of which are as follows: it includes a sewage treatment tank 1, the interior of which is divided into two main spaces by a partition: a filtration chamber 3 and a cleaning chamber 4. The filtration chamber 3 is designed to be wider at the top and narrower at the bottom to facilitate the inflow of sewage and its step-by-step filtration; the cleaning chamber 4 is designed to be narrower at the top and wider at the bottom to facilitate the collection and discharge of sediment.

[0039] The filter chamber 3 is arranged from top to bottom as follows: a multi-stage filter screen 31, a micro impurity filter screen 32, and a medium-level filter layer 33. The multi-stage filter screen 31 is used to initially filter out larger impurities. It has no fewer than three layers, and the mesh size of the filter screen gradually increases from top to bottom to ensure the filtration effect. The micro impurity filter screen 32 is located below the multi-stage filter screen 31. Its mesh size is larger than that of the adjacent multi-stage filter screen 31. It is used to further filter out fine impurities. The micro impurity filter screen 32 is provided with a drive chamber 35 and a telescopic rotation mechanism 36 on one side. The medium-level filter layer 33 is made of carbon or sand, or a combination of both, for deep purification of water quality.

[0040] The cleaning chamber 4 is equipped with a baffle plate 41 corresponding to the multi-stage filter screen 31. The baffle plate 41 can be pushed by the first push rod 42 on the outside to control the baffle plate 41 to move closer to or away from the baffle. A high-pressure flushing gun head 43 is installed corresponding to the micro impurity filter screen 32 to flush the impurities on the surface of the filter screen.

[0041] The partition has a drain window 21 and a passage window 22. The drain window 21 is located between the multi-stage filter screen 31 and the partition, allowing the push bucket 341 to pass through and discharge the impurities accumulated on the multi-stage filter screen 31. The passage window 22 is located between the micro impurity filter screen 32 and the high-pressure flushing head 43, allowing the micro impurity filter screen 32 to pass through and be flushed below the high-pressure flushing head 43.

[0042] Example 2

[0043] like Figure 1-4 As shown, a sewage inlet pipe 11 is installed at the top of the sewage treatment tank 1, which is connected to the filter chamber 3 and is used to introduce sewage to be treated; a drain pipe 12 is provided on the front of the filter chamber 3, located below the medium filter layer 33, for discharging filtered clean water; a sludge discharge guide hopper 13 is provided near the bottom of the cleaning chamber 4 to facilitate the collection and discharge of sediment.

[0044] The cleaning assembly 34 includes a push bucket 341, a second cylinder 342, and a scraper 343. The push bucket 341 is parallel to the drain window 21 and is pushed by the second cylinder 342. The scraper 343 is attached to the multi-stage filter screen 31 to clean up accumulated impurities and push them into the drain window 21.

[0045] The telescopic rotation mechanism 36 includes a motor 361, a third cylinder 362, and a sliding component 363. The output end of the motor 361 extends into the filter chamber 3 to fix the rotating disk 321, driving the micro impurity filter screen 32 to rotate. The third cylinder 362 fixes the outer shell of the motor 361, and the sliding component 363 ensures the stable sliding of the motor 361 and the rotating disk 321 within the drive chamber 35.

[0046] The sliding component 363 is selected from either a slider guide rail assembly or a slider rod assembly.

[0047] When the first push rod 42 pushes the barrier plate 41 to the partition plate 2, the barrier plate 41 is engaged in the barrier plate engaging groove 411, and the edge is provided with a waterproof pad to ensure sealing.

[0048] The micro impurity filter screen 32 is mounted on a rotating disk 321 on the side near the telescopic rotating mechanism 36. The mesh size of the micro impurity filter screen 32 is greater than that of the adjacent multi-stage filter screen 31.

[0049] The working process of this utility model is as follows: When using a sewage treatment tank 1 for sewage treatment, the sewage to be treated is first introduced into the filter chamber 3 through the sewage inlet pipe 11. The sewage undergoes preliminary filtration through multi-stage filter screens 31, where larger impurities are trapped on the screen surface. As the sewage continues to flow, it undergoes further filtration through micro-impurity filter screens 32, where fine impurities are trapped. After the sewage undergoes deep purification through a medium-density filter layer 33, it is finally discharged from the drain pipe 12.

[0050] When cleaning is required (timed), the valve of the pre-filter sewage inlet pipe 11 is closed to prevent sewage from entering. The second cylinder 342 is activated to push the push bucket 341 and scraper pad 343 to clean the impurities on the multi-stage filter screen 31 and push it into the drain window 21. At the same time, the first cylinder retracts to open the partition, opening the drain window 21. For the micro-impurity filter screen 32, the third cylinder 362 extends to drive the micro-impurity filter screen 32 through the window 22. Through the rotation of the motor 361 (180-degree rotation), it enters the area below the high-pressure flushing gun head 43 for flushing to ensure the cleanliness of the filter screen. Finally, it is reset. During this process, the dirt discharge guide bucket 13 discharges the sediment accumulated in the cleaning chamber 4.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
