Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage pool. Background Art

[0002] Water is a commonly used resource in daily life and industrial production. In order to improve the safety and convenience of people's water use, water treatment plants are usually used to purify and disinfect water resources to produce water that meets the corresponding standards for people's life and production. Domestic water is mainly drawn from rivers, lakes, groundwater, and surface water through the water plant's water intake pump station. The water plant is treated by sedimentation, disinfection, filtration and other process flows in accordance with the "National Sanitary Standards for Drinking Water". Finally, it is delivered to each user through a water distribution pump station. In the process of water treatment, the water plant will produce a large amount of sewage after filtration. This sewage is usually stored in a sewage pool and then transported to the treatment device for treatment.

[0003] For example, the patent document with publication number CN107524226A discloses a sewage pool, including a water storage pool, a downpipe arranged at the bottom of the water storage pool, the downpipe is a square structure, the top of the left end of the square structure protrudes an opening as a water inlet connected to the water outlet of the water storage pool, and the bottom of the right end of the square structure protrudes an opening as a water outlet connected to the sewer; the water inlet of the square structure extends to the inside of the square structure, 4-8 cm away from the bottom, and the water outlet of the square structure extends to the inside of the square structure, 4-8 cm away from the bottom. This technical solution provides a sewage pool, the bottom downpipe adopts a square structure, the original annular structure is designed as an integrated type, not easy to damage, and two inspection ports are designed, which are convenient for dredging when sewage is blocked.

[0004] Although the above technical solution can realize convenient and quick unclogging of the blockage in the sewage pool, when the sewage is stored in the sewage pool, since the sewage usually contains a lot of solid impurities such as mud and sand, when the sewage is stored in the sewage pool, the mud and sand impurities in the sewage are easily precipitated under the action of gravity, resulting in the accumulation of mud and sand impurities at the bottom of the sewage pool, affecting the normal operation of the sewage pool. For this reason, it is necessary to clean the sewage pool regularly, which increases the maintenance cost of the sewage pool. Utility Model Content

[0005] The utility model aims to provide a sewage pool to solve the technical problem in the prior art that sediment impurities are accumulated at the bottom of the sewage pool, thus affecting the normal operation of the sewage pool.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sewage pool, including a pool body, wherein the pool body is provided with a sludge-preventing mechanism, wherein the sludge-preventing mechanism includes an aeration pipe network, wherein the aeration pipe network is laid at the bottom of the pool body, wherein the aeration pipe network is filled with compressed gas, wherein the aeration pipe network is provided with a plurality of nozzles, wherein the nozzles spray the compressed gas in the aeration pipe network into the pool body.

[0007] The principle and advantage of this scheme are: when treating sewage, the water pool body collects the sewage generated in the production process and temporarily stores it. During the storage process, the anti-sludge sinking mechanism in the water pool body transmits high-pressure gas into the water pool body, so that the sewage stored in the water pool body can continuously roll under the impact of the high-pressure gas, avoiding the sewage in the water pool body from being in a static state for a long time, causing the sludge and impurities in the sewage to be stratified and accumulated at the bottom of the water pool body under the action of gravity, thereby preventing the sludge in the sewage from sinking to the bottom, avoiding the accumulation of sludge in the water pool body, and reducing the cleaning and maintenance costs of the water pool body. In addition, this scheme makes the sewage roll by injecting gas into the water pool body, simplifies the mechanical structure in the water pool body, ensures that the anti-sludge sinking mechanism can operate normally in the sewage, and reduces the maintenance cost of the anti-sludge sinking mechanism.

[0008] Preferably, as an improvement, a rotating member is provided between the nozzle and the aeration pipe network, and the rotating member is used to drive the nozzle to rotate, so that when the compressed gas is sprayed, the nozzle can adjust the spray angle of the compressed gas according to the actual situation, reduce the coverage dead angle when the nozzle sprays the gas, and ensure the stirring effect of the anti-sludge settling device on the sewage.

[0009] Preferably, as an improvement, a one-way valve is provided between the nozzle and the aeration pipe network, and the one-way valve is used to control the one-way connection from the aeration pipe network to the nozzle, so as to avoid sewage backflowing into the aeration pipe network through the nozzle, causing sludge and impurities in the sewage to accumulate in the aeration pipe network, thereby avoiding blockage of the aeration pipe network.

[0010] Preferably, as an improvement, a sewage pump is provided in the water pool body, the output port of the sewage pump is connected to the outlet pipe, and the sewage pump is used to pump the sewage in the water pool body to the outlet pipe. The sewage in the water pool body is pumped out and discharged by the sewage pump, so that the sewage in the water pool body and the impurities in the sewage can be quickly discharged from the water pool body under the negative pressure of the sewage pump, and it is avoided that when the sewage is naturally discharged through the drain outlet under the action of gravity, the sludge in the sewage is attached and deposited at the drain outlet due to the pressure and speed of the sewage discharge, resulting in blockage of the drain outlet.

[0011] Preferably, as an improvement, a water pump lifting mechanism is further provided in the water pool body, the water pump lifting mechanism is connected to the sewage pump, and the water pump lifting mechanism is used to drive the sewage pump to move up and down in the height direction in the water pool body. When the sewage pump extracts sewage from the water pool body, the height of the sewage pump can be adjusted according to the water level of the sewage in the water pool body, so as to ensure that the position of the sewage pump matches the actual situation.

[0012] Preferably, as an improvement, the water pump lifting mechanism includes a bracket, one end of which is connected to the water pool body, and the other end of which extends upward in the height direction; a telescopic member is provided on the top of the bracket, one end of which is fixedly connected to the bracket, and the other end of which extends into the water pool body in the height direction, and one end of the telescopic member located in the water pool body is connected to the sewage pump. This ensures that when the position of the sewage pump is adjusted, the mechanical structure of the telescopic member in the sewage pool can be reduced, and the telescopic member is prevented from being immersed in the sewage pool for a long time, resulting in blockage of the telescopic structure of the telescopic member, which affects the normal operation of the telescopic member. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a schematic diagram of the sewage pool structure in an embodiment of the utility model. DETAILED DESCRIPTION

[0014] The following is further described in detail through specific implementation methods:

[0015] The reference numerals in the drawings of the specification include: pool body 1, water inlet pipe 101, sludge anti-settling mechanism 2, aeration pipe network 201, air supply pipe 202, nozzle 203, rotating part 204, one-way valve 205, water outlet pipe 3, sewage pump 4, water pump lifting mechanism 5, bracket 501, telescopic part 502.

[0016] As attached Figure 1 As shown, a sewage pool includes a pool body 1, in which a sludge anti-sinking mechanism 2 is provided. The sludge anti-sinking mechanism is used to fill gas into the pool body 1 so that the sewage contained in the pool body 1 can be stirred to prevent the sludge in the sewage contained in the pool body 1 from sinking to the bottom.

[0017] The input port of the pool body 1 collects the sewage generated during the production process through the water inlet pipe 101 and transports it to the pool body 1 for storage. Specifically, in this embodiment, the pool body 1 is used to collect and store the sewage generated during the operation of the filtering device.

[0018] The anti-sludge precipitation mechanism includes an aeration network 201, which is laid at the bottom of the pool body 1. One end of the aeration network 201 is connected to a gas pipe 202, and one end of the gas pipe 202 away from the aeration network 201 is connected to a compressed gas tank or an air compressor. The gas pipe 202 is used to transport compressed gas into the aeration network 201. A plurality of nozzles 203 are connected to the aeration network 201, and the plurality of nozzles 203 are evenly distributed at the bottom of the pool body 1. The output ports of the nozzles 203 face the top of the pool body 1, and the nozzles 203 are used to spray the compressed gas in the aeration network 201 into the pool body 1. Compressed gas is sprayed upward from the bottom of the sludge pool through multiple nozzles 203, so that the sewage at the bottom of the pool body 1 can roll upward under the push of the compressed gas, ensuring that the sewage in each area of ​​the pool body 1 can be in a flowing state, so that the sewage and sludge stored in the pool body 1 can be in a mixed state, avoiding stratification and sedimentation of sludge in the sewage.

[0019] A rotating member 204 is provided between the nozzle 203 and the aeration pipe network 201. The rotating member 204 is used to drive the nozzle 203 to rotate, so as to adjust the angle between the central axis of the nozzle 203 and the aeration pipe network 201. The base of the rotating member 204 is fixedly connected to the aeration pipe network 201 by a buckle, and the nozzle 203 and the rotating shaft of the rotating member 204 are fixedly connected by a buckle or a bolt. In this embodiment, the rotating member 204 can be a servo motor. When the compressed gas is sprayed, the nozzle 203 can adjust the spray angle of the compressed gas according to the actual situation, reduce the coverage dead angle when the nozzle 203 sprays the gas, and ensure the turning effect of the anti-sludge settling device on the sewage.

[0020] A one-way valve 205 is also provided between the nozzle 203 and the aeration pipe network 201, wherein one end of the one-way valve 205 is connected to the aeration pipe network 201, and the other end of the one-way valve 205 is connected to the nozzle 203. The one-way valve 205 is used to control the one-way connection from the aeration pipe network 201 to the nozzle 203, so as to prevent sewage from flowing back into the aeration pipe network 201 through the nozzle 203, causing sludge and impurities in the sewage to accumulate in the aeration pipe network 201, thereby preventing the aeration pipe network 201 from being blocked.

[0021] The output port of the pool body 1 is provided with an outlet pipe 3, and one end of the inlet and outlet pipe 3 specifically extends from the top of one side of the pool body 1 into the pool body 1, and the other end of the outlet pipe 3 is connected to the sewage treatment device. The end of the outlet pipe 3 located in the pool body 1 is connected to the sewage pump 4, and the sewage pump 4 is specifically placed in the pool body 1, and the output port of the sewage pump 4 is connected to the outlet pipe 3. The sewage pump 4 is used to extract the sewage in the pool body 1 into the outlet pipe 3, so that the sewage in the pool body 1 is transported to the sewage treatment device through the outlet pipe 3 for treatment. The sewage in the pool body 1 is extracted and discharged by the sewage pump 4, so that the sewage in the pool body 1 and the impurities in the sewage can be quickly discharged from the pool body 1 under the negative pressure of the sewage pump 4, so as to avoid the sludge in the sewage being attached and deposited at the drain outlet due to the pressure and speed factors when the sewage is discharged, resulting in blockage of the drain outlet.

[0022] A water pump lifting mechanism 5 is provided in the pool body 1, and the sewage pump 4 is fixedly installed on the water pump lifting mechanism 5 by bolts. The water pump lifting mechanism 5 is used to drive the sewage pump 4 to move up and down in the pool body 1 along the height direction. The specific water pump lifting mechanism 5 is located above the pool body 1, wherein the water pump lifting mechanism 5 includes a bracket 501, and the bracket 501 is fixedly connected to the side wall of the pool body 1 by bolts. One end of the bracket 501 is fixedly connected to the pool body 1, and the other end extends upward along the height direction. A telescopic member 502 is fixedly connected to the top of the bracket 501 by bolts, and one end of the telescopic member 502 is fixedly connected to the bracket 501, and the other end extends into the pool body 1 along the height direction, and one end of the telescopic member 502 located in the pool body 1 is fixedly connected to the sewage pump 4 by bolts. Preferably, in this embodiment, the telescopic member 502 is an electric telescopic rod, and other telescopic members 502 can also be selected in other embodiments. The telescopic member 502 is used to drive the sewage pump 4 to move up and down in the height direction. When the sewage pump 4 extracts the sewage in the pool body 1, the height of the sewage pump 4 can be adjusted according to the water level of the sewage in the pool body 1, so as to avoid the sewage pump 4 directly extracting the relatively thick sewage at the bottom of the pool body 1, thereby increasing the load of the sewage pump 4 and reducing the life of the sewage pump 4. At the same time, it can avoid the sewage pump 4 from extracting sewage diluted by a higher water level, so that the sludge content in the pool body 1 is accumulated and increased; by adjusting the position of the sewage pump 4, the position of the sewage pump 4 for extracting sewage can be more reasonable, ensuring that the sewage in the pool body 1 is extracted by the sewage pump 4 with the decrease of the water level and the tumbling and mixing action of the anti-sludge sinking mechanism 2. The consistency of the output sewage quality is guaranteed.

[0023] The specific implementation process is as follows:

[0024] When treating sewage, the water pool body 1 collects sewage generated during the production process and temporarily stores it. During the storage process, the anti-sludge sinking mechanism 2 in the water pool body 1 delivers high-pressure gas into the water pool body 1, so that the sewage stored in the water pool body 1 can continuously roll under the impact of the high-pressure gas, thereby preventing the sewage in the water pool body 1 from being in a static state for a long time, causing the sludge and impurities in the sewage to be stratified and accumulated at the bottom of the water pool body 1 under the action of gravity, thereby preventing the sludge in the sewage from sinking to the bottom, preventing the water pool body 1 from being accumulated by sludge, and reducing the cleaning and maintenance costs of the water pool body 1. In addition, this solution causes the sewage to roll by injecting gas into the water pool body 1, simplifies the mechanical structure in the water pool body 1, ensures that the anti-sludge sinking mechanism 2 can operate normally in the sewage, and reduces the maintenance cost of the anti-sludge sinking mechanism 2.
