Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically a sewage stirring, filtering and cleaning device. Background Technology

[0002] Application number CN201920951976.5 discloses a wastewater mixing and filtration device, including an inlet pipe, a dosing tank, a mixing tank, a sedimentation tank, and a filtration device. The upper parts of the mixing tank and the sedimentation tank are connected. The inlet pipe extends to the bottom of the mixing tank. The dosing tank is located on the inlet pipe outside the mixing tank, and its outlet end is connected to the inlet pipe. An outlet channel is provided at the upper part of the sedimentation tank, and the filtration device is located at the outlet channel. The filtration device includes a screen conveyor and a discharge conveyor. The screen conveyor is inclined, with its lower part located within the outlet channel, and the discharge conveyor located at the discharge end of the screen conveyor. This device can reduce equipment investment costs, reduce equipment energy consumption, and improve filtration efficiency. However, this patent still has the following problems in actual use:

[0003] When the above-mentioned device drains water, the filter screen is positioned high, requiring a continuous supply of new water through the water injection pipe. This causes the wastewater that has completed settling in the sedimentation tank to overflow. However, the newly injected wastewater will automatically diffuse and is difficult to control. As a result, during the overflow process, the newly injected wastewater will inevitably pass through the filter screen as well, leading to a reduction in the overall sedimentation effect of the sedimentation tank.

[0004] A wastewater stirring, filtering and cleaning device is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a sewage stirring and filtration cleaning device to solve the problem that, in the above-mentioned device mentioned in the background art, when draining water, the filter screen is positioned high, which requires a continuous injection of new water through a water injection pipe to cause the sewage that has completed sedimentation in the sedimentation tank to overflow. However, the newly injected sewage will automatically diffuse and is difficult to control, which means that during the overflow of the sewage that has completed sedimentation, the newly injected sewage will inevitably pass through the filter screen as well, resulting in a reduction in the overall effect of sewage sedimentation in the sedimentation tank.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewage stirring and filtration cleaning device, comprising a filter box, the filter box comprising a box body, a water inlet pipe connected to the top side of the box body, a control valve fixedly installed at the bottom of the filter box, and a screw conveyor installed at the bottom of the control valve;

[0007] A drainage assembly is provided on one side of the bottom of the housing. The drainage assembly includes a drain pipe, which is fixedly connected to the bottom of the housing. A first motor is fixedly installed on the outside of the right side of the drain pipe. The output end of the first motor extends into the drain pipe and is fixedly connected to a drive shaft. A filter screen is fixedly connected inside the drain pipe. The drive shaft passes through the filter screen and is fixedly connected to an arc-shaped scraper. A sludge discharge trough is provided below the arc-shaped scraper. A sludge storage shell is fitted into the bottom of the drain pipe. A sludge inlet trough is opened on one side of the top of the sludge storage shell. A water outlet trough is opened on the other side of the top of the sludge storage shell. A water return net is provided above the water outlet trough. The arc-shaped scraper is in contact with the surface of the filter screen. The water return net is located on the right side of the filter screen, and the sludge inlet trough is located on the left side of the filter screen.

[0008] The box is equipped with a stirring mechanism inside.

[0009] Preferably, the sewage discharge trough is located at the bottom of the drain pipe and is connected to the sewage inlet trough. A return water hole is provided above the outlet trough at the bottom of the drain pipe. The return water net is fixedly installed in the return water hole and is connected to the outlet trough. A water valve is installed at the end of the drain pipe.

[0010] Preferably, mounting plates are symmetrically fixedly connected to both sides of the sludge storage shell, a sliding folding plate is slidably connected to the bottom surface of the mounting plate, a spring is fixedly connected to the outer side of the sludge storage shell, a lever is fixedly connected to the bottom of the sliding folding plate, and suspension brackets are symmetrically provided on both sides of the sludge storage shell, with the sliding folding plate inserted into the suspension brackets.

[0011] Preferably, the bottom of the suspension bracket is threaded with a button, the top of the button is rotatably connected with a pad, the pad is in contact with the bottom surface of the sliding folding plate, and the suspension bracket is fixedly connected to the bottom of the drain pipe.

[0012] Preferably, the stirring mechanism includes an installation chamber fixed to the top surface of the box body, an outer shaft rotatably connected to the bottom of the installation chamber, an inner shaft passing through the inside of the outer shaft, a second gear fixedly connected to the top of the inner shaft, and a third gear fixedly connected to the top of the outer shaft.

[0013] Preferably, a side shaft is rotatably connected to the side of the installation chamber, and a fan blade is fixedly connected to the outside of the side shaft. One side of the fan blade is located directly below the water outlet of the water inlet pipe. A spare motor is fixedly connected to the top of the housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are: this sewage stirring and filtration cleaning device avoids filter screen clogging affecting drainage, while facilitating the cleaning and recovery of impurities filtered by the filter screen. It avoids the need to add new sewage during drainage, preventing some sewage from flowing out without being fully treated. It ensures that the discharged sewage and the agent are fully mixed and settled. The specific details are as follows:

[0016] 1. The first motor, using the drive shaft and arc-shaped scraper, causes the impurities accumulated on the filter screen to move outward due to centrifugal force. Finally, under the combined push of the water flow and the arc-shaped scraper, they enter the sludge storage tank through the drain trough and the inlet trough. This avoids filter screen clogging affecting drainage, facilitates the cleaning and recycling of impurities filtered by the filter screen, and ensures a lower amount of residual sewage in the tank. It also avoids the need to add new sewage during drainage, which would cause some sewage to flow out without being fully treated. This ensures that the discharged sewage and the agent are fully mixed and settled.

[0017] 2. When water is injected through the inlet pipe, the water flow washes one side of the fan blades, causing the side shaft to drive the first gear to rotate. This, in turn, causes the second and third gears to rotate simultaneously and in opposite directions. Consequently, the inner and outer shafts drive the stirring rods to rotate in opposite directions, performing preliminary stirring of the injected sewage without power, increasing the mixing effect between the chemicals and the sewage, and thus increasing the sewage treatment efficiency.

[0026] A drainage assembly 2 is provided on the bottom side of the housing 101. The drainage assembly 2 includes a drain pipe 201, which is fixedly connected to the bottom of the housing 101. A first motor 203 is fixedly installed on the outside of the right side of the drain pipe 201. The output end of the first motor 203 extends into the drain pipe 201 and is fixedly connected to a drive shaft 204. A filter screen 202 is fixedly connected inside the drain pipe 201. The drive shaft 204 passes through the filter screen 202 and is fixedly connected to an arc-shaped scraper 205. A sewage trough 207 is provided below the arc-shaped scraper 205. A drain pipe 207 is snapped onto the bottom of the drain pipe 201. The sludge storage shell 209 has a sludge inlet trough 210 on one side of its top and a water outlet trough 211 on the other side of its top. A return water net 208 is provided above the water outlet trough 211. An arc-shaped scraper 205 is attached to the surface of the filter screen 202.

The two ends of the arc-shaped scraper 205 are attached to the inner wall of the drain pipe 201. The drain pipe 201 is a pipe with a square outer shape and a round inner shape. The drive shaft 204 is rotatably connected to the filter screen 202. The drain pipe 201 is located on the right side of the housing 101.

[0027] The internal structure of the housing 101 is equipped with a stirring mechanism 3.

[0028] A sewage trough 207 is located at the bottom of the drain pipe 201 and is connected to the sewage inlet trough 210. A return water hole 206 is located above the outlet trough 211 and is located at the bottom of the drain pipe 201. A return water net 208 is fixedly installed in the return water hole 206 and is connected to the outlet trough 211. A water valve is installed at the end of the drain pipe 201. The water valve is a non-existent technology and can control whether to drain water. After the sewage storage shell 209 is disassembled, the return water net 208 is directly exposed and can be cleaned directly.

[0029] The sludge storage shell 209 is symmetrically fixedly connected to two sides of the mounting plate 214. The bottom surface of the mounting plate 214 is slidably connected to the sliding folding plate 215. The sliding folding plate 215 is fixedly connected to the outer side of the sludge storage shell 209 by a spring 216. The bottom of the sliding folding plate 215 is fixedly connected to the lever plate 217. The sludge storage shell 209 is symmetrically provided with a suspension bracket 212 on both sides. The sliding folding plate 215 is inserted into the suspension bracket 212. The spring 216 will push the sliding folding plate 215 to insert into the inner side of the suspension bracket 212. A sealing ring is fixed on the top side of the sludge storage shell 209.

[0030] The bottom of the suspension bracket 212 is threaded with a screw 213, and the top of the screw 213 is rotatably connected with a pad. The pad is in contact with the bottom surface of the sliding folding plate 215, and the suspension bracket 212 is fixedly connected to the bottom of the drain pipe 201. The screw 213 can provide further compression to the sliding folding plate 215, so that the sludge storage shell 209 is tightly attached to the bottom of the drain pipe 201.

[0031] The stirring mechanism 3 includes an installation chamber 301 fixed to the top surface of the housing 101. An outer shaft 304 is rotatably connected to the bottom of the installation chamber 301. An inner shaft 303 passes through the inside of the outer shaft 304. A second gear 308 is fixedly connected to the top of the inner shaft 303. A third gear 309 is fixedly connected to the top of the outer shaft 304. The inner shaft 303 and the outer shaft 304 are rotatably connected.

[0032] A side shaft 305 is rotatably connected to the side of the installation chamber 301. A fan blade 306 is fixedly connected to the outside of the side shaft 305. One side of the fan blade 306 is located directly below the water outlet of the water inlet pipe 102. A spare motor 302 is fixedly connected to the top of the housing 101. The output end of the spare motor 302 extends into the installation chamber 301 and is fixedly connected to the top of the inner shaft 303. A first gear 307 is fixedly connected to one end of the side shaft 305 that extends into the installation chamber 301. The first gear 307 meshes with the second gear 308 and the third gear 309 simultaneously. When the water flow impact force is too small during water injection, the inner shaft 303 can be rotated by starting the spare motor 302 to achieve stirring. The first gear 307, the second gear 308, and the third gear 309 are all bevel gears. The first gear 307 is located between the second gear 308 and the third gear 309.

[0033] A stirring rod 311 is fixedly connected to the outside of both the outer shaft 304 and the inner shaft 303. A stabilizing rod 310 is rotatably connected to the bottom end of the inner shaft 303. The stabilizing rod 310 is fixedly connected to the inner wall of the housing 101. The stabilizing rod 310 can provide stable support for the rotation of the inner shaft 303.

[0034] Working principle: Before using this type of sewage mixing and filtration cleaning device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, during drainage, impurities in the sewage are first filtered by the filter screen 202. Then, the first motor 203 is started, which drives the arc-shaped scraper 205 to rotate through the drive shaft 204. This causes the impurities accumulated on the filter screen 202 to move outward due to centrifugal force. Finally, under the combined push of the water flow and the arc-shaped scraper 205, the impurities enter the sludge storage tank 209 through the sewage discharge tank 207 and the sewage inlet tank 210. This avoids clogging of the filter screen 202 and facilitates the cleaning and recycling of the impurities filtered by the filter screen 202. Moreover, it ensures that the height of the residual sewage or impurities in the entire tank 101 is lower than that of the drain pipe 201, avoiding the need to add new sewage during drainage, which would cause some sewage to flow out before it has settled sufficiently. This ensures that the sewage and the chemicals are fully mixed and settled during drainage.

[0035] The outlet trough 211 and the return water net 208 make it possible for water to enter from the drain trough 207 and exit from the return water net 208 during drainage, which makes it easier for impurities pushed to the bottom of the filter screen 202 to enter the sludge storage shell 209.

[0036] When it is necessary to clean the sludge storage shell 209, the sliding folding plate 215 is no longer in close contact with the pad by rotating the screw 213. At this time, the sliding folding plate 215 is moved by pulling the lever 217 and removed from the suspension bracket 212, so that the sludge storage shell 209 can be quickly disassembled and cleaned.

[0037] When water is injected into the inlet pipe 102, the water flow will wash one side of the fan blade 306, which will cause the side shaft 305 to drive the first gear 307 to rotate, which will cause the second gear 308 and the third gear 309 to rotate simultaneously and in opposite directions, which will cause the inner shaft 303 and the outer shaft 304 to drive the stirring rod 311 to rotate in opposite directions, performing preliminary stirring of the injected sewage without power, increasing the mixing effect of the agent and sewage, thereby increasing the sewage treatment efficiency;

[0038] When the water flow impact force during water injection is too small, stirring can also be achieved by starting the backup motor 302 to drive the inner shaft 303 to rotate.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
