Description

Technical Field

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

[0002] Coagulants are used to treat fine suspended solids and colloidal particles in wastewater that are difficult to remove by natural sedimentation. Adding coagulants to wastewater can reduce turbidity and color, and remove certain heavy metals, radioactive substances, and high molecular weight organic matter. Coagulants are usually added before the solid-liquid separation process. In order to improve the coagulation effect, the coagulant needs to be combined with the wastewater quickly and evenly.

[0003] For example, Chinese Patent CN219023971U discloses a wastewater treatment device for chemical dosing, which proposes that "through the coordinated arrangement of a distributor, a distributor pipe, and a water mist nozzle, the coagulant can be evenly injected into the wastewater tank through the water mist nozzle." However, the distributor pipe and the water mist nozzle of this device are in fixed positions during operation, and the fixed spray range makes the coagulant diffusion rate slow, which easily leads to agglomeration during transportation, causing blockage of the distributor pipe and the water mist nozzle, and the binding efficiency with wastewater is low. Therefore, this utility model proposes a wastewater treatment tank for evenly dispensing wastewater treatment coagulant to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a wastewater treatment tank for uniformly dispensing coagulant, thereby solving the problem in the prior art where the fixed position and spray range of the flow pipe and water mist nozzle result in a slow coagulant diffusion rate.

[0006] A further improvement is made in that: the flow distribution mechanism includes a main channel, a branch channel, a transfer pipe and a spray pipe. The main channel is fixedly connected to the upper part of the inside of the sewage tank. A set of branch channels are symmetrically connected to both sides of the main channel. Transfer pipes are symmetrically installed on both sides of the top of the sewage tank. Multiple spray pipes are connected to one side of the transfer pipe. One end of the spray pipe extends into the inside of the branch channel.

[0007] A further improvement is that: a set of interfaces are symmetrically provided on both sides of the main hole groove, one end of the branch hole groove is fitted with the interface, and a set of connectors are symmetrically provided on both sides of the main hole groove. The connectors are L-shaped, and the two sides of the connectors are fixedly connected to the main hole groove and the branch hole groove by screws respectively.

[0008] A further improvement is made in that: the conveying mechanism includes a conveying pipe, a water pump and a storage bin, the storage bin is provided on one side of the top of the support frame, the water pump is installed on one side of the sewage tank, the input end of the water pump is connected to the bottom of the storage bin through the conveying pipe, the output end of the water pump is connected to the transfer pipe through the conveying pipe, and the two transfer pipes are also connected to each other through the conveying pipe.

[0009] A further improvement is that a motor is fixedly installed on the top of the box cover, a material discharge mechanism is provided at the bottom of the box cover, and a material extraction port is provided on one side of the top of the box cover.

[0010] A further improvement is made in that: the discharge mechanism includes a screw and a scraper, the bottom of the box cover is rotatably connected to the screw, the outside of the screw is fixedly connected to the scraper, the outside of the scraper is in close contact with the inner wall of the hopper, and the output end of the motor is fixedly connected to the top of the screw.

[0011] A further improvement is that a protective shell is fixedly installed on the top of the box cover, the protective shell is wrapped around the motor, and multiple anti-collision strips are fixedly connected to the outside of the protective shell.

[0012] The beneficial effects of this utility model are as follows: the coagulant inside the storage silo can be transported to the interior of one of the transfer pipes via a water pump and a conveying pipe, and then transported to the interior of another transfer pipe via a conveying pipe. The transfer pipe sprays the coagulant into the interior of the main hole groove and the branch hole groove through the spray pipe. The coagulant is evenly distributed inside the sewage tank through the leakage holes on the main hole groove and the branch hole groove, which accelerates the fusion of the coagulant and the sewage.

A flow distribution mechanism is provided at the top of the support frame 1, and the top of the support frame 1 is equipped with... The device has a conveying mechanism. When in use, sewage is injected into the sewage tank 2 through the feed inlet 6. Then, the coagulant is conveyed into the distribution mechanism through the conveying mechanism. The distribution mechanism evenly conveys the coagulant into the sewage tank 2, so that the coagulant and sewage inside the sewage tank 2 are evenly mixed. The coagulant can ionize and hydrolyze in the sewage, forming colloids with different charges than impurities in the sewage.

The two transfer pipes 9 are also connected to each other through the conveying pipe 12. The coagulant is poured into the interior of the storage silo 18. The transfer pipe 9 is connected to the storage silo 18 through the water pump 13 and the conveying pipe 12. The coagulant inside the storage silo 18 can be conveyed to the interior of one of the transfer pipes 9 through the water pump 13 and the conveying pipe 12, and then conveyed to the interior of the other transfer pipe 9 through the conveying pipe 12.

[0021] The distribution mechanism includes a main channel 7, branch channels 8, a transfer pipe 9, and a spray pipe 10. The main channel 7 is fixedly connected to the upper part of the inside of the sewage tank 2. A set of branch channels 8 are symmetrically connected to both sides of the main channel 7.

The transfer pipe 9 sprays coagulant into the inside of the main channel 7 and the branch channels 8 through the spray pipes 10. The coagulant is evenly distributed inside the sewage tank 2 through the leakage holes on the main channel 7 and the branch channels 8, which accelerates the fusion of coagulant and sewage. The coagulant has a better effect on coagulating impurities in sewage. The coagulated impurities then settle in the collection hopper 3 at the bottom of the sewage tank 2.

The top end of the screw 14 and the output end of the motor 16 are connected as one unit. The output end of the motor 16 can drive the screw 14 to rotate inside the hopper 3. The screw 14 drives the impurities to move downward, opening the valve on the discharge pipe 4, and discharging them downward into the hopper 3 through the discharge pipe 4. The scraper 15 is fixed to the screw 14 as one unit. The screw 14 can drive the scraper 15 to rotate inside the hopper 3. The scraper 15 can scrape the impurities on the inner wall of the hopper 3, greatly increasing the discharge rate of impurities in the hopper 3. After the impurities are discharged, the valve on the discharge pipe 4 is closed.

Multiple anti-collision strips are fixedly connected to the outside of the protective shell. The protective shell and anti-collision strips can isolate the motor 16 from external objects, prevent external objects from directly contacting the motor 16, and protect the motor 16.

[0026] The wastewater treatment coagulant is evenly added to the wastewater treatment tank. The coagulant inside the storage silo 18 can be transported to one of the transfer pipes 9 via the water pump 13 and the conveying pipe 12, and then to the other transfer pipe 9 via the conveying pipe 12. The transfer pipe 9 sprays the coagulant into the main hole groove 7 and the branch hole groove 8 through the spray pipe 10. The coagulant is evenly distributed inside the wastewater tank 2 through the leakage holes on the main hole groove 7 and the branch hole groove 8, which accelerates the fusion of the coagulant and the wastewater. The coagulant has a better effect on coagulating impurities in the wastewater. The coagulated impurities then settle in the collection hopper 3 at the bottom of the wastewater tank 2.
