Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to an anti-clogging sewage treatment tank. Background Technology

[0002] In the field of wastewater treatment, traditional wastewater treatment tanks face many challenges in the feeding stage. Wastewater often contains a large number of floating impurities. If these impurities are directly introduced into the treatment tank, they can easily cause blockages in the pipes and treatment components, seriously affecting the normal operation and treatment efficiency of the wastewater treatment system. To solve this problem, the common practice is to install a filter screen at the inlet to remove floating impurities from the wastewater.

[0003] However, existing filter screens have significant drawbacks in practical applications. Firstly, after filtration, manual cleaning is required, a cumbersome process that consumes considerable manpower and time. Furthermore, manual cleaning is ineffective, failing to thoroughly remove various impurities adhering to the screen, leading to a gradual decline in the filter's performance and ultimately affecting the overall wastewater treatment effect. Secondly, some existing filter screens can only filter out larger impurities, failing to effectively intercept tiny particles and flocculent matter. With prolonged use, unfiltered micro-impurities gradually settle into sludge, accumulating at the bottom of the treatment tank. This sludge accumulation not only occupies treatment space but also negatively impacts water quality and treatment efficiency, necessitating frequent cleaning and maintenance, increasing operating costs and management complexity. Therefore, a multi-stage filtration system was designed to more comprehensively and efficiently filter various impurities in wastewater, while also providing sludge removal to reduce sludge blockage in the pipes. Utility Model Content

[0004] The purpose of this invention is to provide a clog-resistant sewage treatment tank with multi-stage filtration, which can more comprehensively and efficiently filter various impurities in sewage, and also has a sludge removal function to reduce sludge blockage in pipes.

[0005] The technical implementation scheme of this utility model is as follows:

[0006] A clog-resistant wastewater treatment tank includes a tank body, an inlet, a first filtration mechanism, and a second filtration mechanism. The first and second filtration mechanisms are disposed inside the tank body, with the second filtration mechanism located below the first filtration mechanism. The first filtration mechanism includes a first filter plate, a first rotating shaft, a first chain, a scraper, and a second filter plate. The first filter plate is disposed inside the tank body, and the second filter plate is disposed on the side of the first filter plate. The first rotating shaft is mounted on the tank body via a fixing lug, and the first chain and scraper are disposed on the upper part of the first rotating shaft. A collection trough is disposed below the first and second filter plates, and the outlet of the collection trough is connected to the second filtration mechanism.

[0007] Optionally, a first sprocket is provided on both sides of the first rotating shaft, and the first sprocket is connected to a second sprocket on another rotating shaft through a first chain to form a transmission structure. The scraper is provided on the upper part of the first chain; a plurality of scraper rods are provided on the upper part of the scraper.

[0012] This utility model has the following advantages:

[0013] 1. This utility model includes a first filtration mechanism, a second filtration mechanism, and a material guiding mechanism inside the tank. The first filtration mechanism performs primary filtration on the incoming wastewater, filtering out large floating impurities. The wastewater then undergoes secondary filtration through the second filtration mechanism to remove internal particulate impurities. After two filtrations, the wastewater enters the water tank storage area, preventing blockages during the flow process.

[0014] 2. In this utility model, the first filtration mechanism guides the sewage through the first filter plate, which can filter out large impurities inside. The sewage is then lifted by the scraper on the first chain and sent into the chamber formed by the second filter plate for convenient collection and treatment.

[0015] 3. In this utility model, the second filtration mechanism is a rotating stainless steel mesh belt, which can filter sewage again and remove internal impurities. The stainless steel mesh belt moves and feeds the material, which not only achieves filtration but also facilitates the removal of impurities. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] like Figures 1-6 As shown, a clog-resistant wastewater treatment tank includes a tank body 1, an inlet 2, a first filtration mechanism 3, and a second filtration mechanism 4. The first filtration mechanism 3 and the second filtration mechanism 4 are arranged inside the tank body 1, with the second filtration mechanism 4 located below the first filtration mechanism 3. The first filtration mechanism 3 includes a first filter plate 301, a first rotating shaft 304, a first chain 303, a scraper 305, and a second filter plate 306. The first filter plate 301 is arranged inside the tank body 1, and the second filter plate 306 is arranged on the side of the first filter plate 301. The first rotating shaft 304 is mounted on the tank body 1 via a fixing lug 302, and the first chain 303 and the scraper 305 are arranged on the upper part of the first rotating shaft 304. A collection trough 7 is arranged below the first filter plate 301 and the second filter plate 306, and the outlet of the collection trough 7 is connected to the second filtration mechanism 4.

[0025] It should be noted that the box body 1 is a rectangular cavity structure with openings at both the top and bottom. A first filtration mechanism 3 is installed inside the box body 1 for the first filtration of sewage. The first filter plate 301 and the second filter plate 306 are both installed inside the box body 1. The first filter plate 301 is inclined inside the box body 1. A first rotating shaft 304 is installed on one side of the first filter plate 301, which can drive the scraper 305 to lift and rotate through the first chain 303 on its upper part. This lifts the impurities filtered by the first filter plate 301 and sends them into the storage tank formed by the second filter plate 306 for temporary storage.

[0026] It should be further explained that the impurities lifted by the scraper 305 have a lot of water stains on their surface. If they are removed directly, wastewater will drip and pollute the work area. Therefore, they are guided into the storage tank formed by the second filter plate 306. The water stains on their surface can be drained by letting them stand for a period of time, and then they can be discharged, thereby maintaining the cleanliness of the work environment.

[0027] like Figures 1-4As shown, first sprockets are provided on both sides of the first rotating shaft 304, and the first sprockets are connected to the second sprocket on the other rotating shaft through the first chain 303 to form a transmission structure. The scraper frame 305 is provided on the upper part of the first chain 303. Several scraper rods are provided on the upper part of the scraper frame 305. The second filter plate 306 is an L-shaped filter plate, and a peeling groove 307 is provided on the part of the second filter plate 306 near the scraper frame 305. A rectangular opening 309 is provided on one side of the housing 1, and a sealing plate 308 is provided inside the rectangular opening 309. A handle 310 is provided on the sealing plate 308.

[0028] It should be noted that the first chain 303 is mounted on the first sprocket of the first rotating shaft 304, and can lift and lower the scraper 305 under the drive of the third drive motor, and lift and transport impurities through the scraper rod on the scraper 305.

[0029] It should be further explained that the second filter plate 306 is provided with a peeling groove 307 near the material rack 305. The scraper rod on the scraper rack 305 can pass through the peeling groove 307 to peel off the impurities and then introduce the impurities into the second filter plate 306.

[0030] like Figures 1-6 As shown, the second filtration mechanism 4 includes a connecting plate 401, a third sprocket 402, a stainless steel mesh belt 403, and a first drive motor. The connecting plate 401 is disposed on both sides of the housing 1, and a second rotating shaft is disposed on the upper part of the connecting plate 401. The third sprocket 402 and a second chain connected to the third sprocket 402 are disposed on the upper part of the second rotating shaft. The stainless steel mesh belt 403 is disposed between the two second chains. One end of the second rotating shaft is connected to the output shaft of the first drive motor through a coupling. A first guide trough 404 is disposed at the lower part of the discharge end of the stainless steel mesh belt 403.

[0031] It should be noted that the stainless steel mesh belt 403 is installed on the third sprocket 402 and is driven by the rotation of the second rotating shaft, thereby filtering the sewage discharged from the collection tank 7 again. The advantage of this design is that the filtered impurities can be transferred through the stainless steel mesh belt 403 and discharged through the guide chute 404, making it convenient for operators to collect.

[0032] like Figures 1-6As shown, it also includes a material guiding mechanism 5, which includes a second material guiding trough 501, a spiral material guiding rod 502, a discharge pipe 503, a discharge port 504, and a second drive motor 505. The second material guiding trough 501 is located at the bottom of the housing 1, and the discharge pipe 503 and the spiral material guiding rod 502 are arranged inside the second material guiding trough 501. The spiral material guiding rod 502 is located inside the discharge pipe 503, and one end of the spiral material guiding rod 502 is connected to the second drive motor 505. The discharge port 504 is arranged at the lower part of the discharge pipe 503. A support frame 6 is arranged at the lower part of the housing 1.

[0033] It should be noted that the feeding mechanism 5 is designed to settle and discharge the sludge in the sewage treatment tank. The bottom of the second feeding trough 501 is equipped with a discharge trough and a discharge pipe 503, which are connected at one end. A spiral feeding rod 502 is built in. When it is necessary to discharge the settled sludge, simply drive the spiral feeding rod 502, and the sludge can be discharged from the discharge port 504, thereby achieving automated processing.
