Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment equipment, specifically to an integrated multi-stage industrial wastewater treatment device. Background Technology

[0002] Industrial wastewater is a byproduct generated during industrial production. Because of the different products produced, industrial wastewater contains more complex components. Direct discharge of industrial wastewater will have a severe impact on the environment, so it needs to be purified.

[0003] There are many integrated wastewater treatment devices on the market, which can be directly assembled in the production industry. However, current integrated treatment devices can only drive the wastewater forward, resulting in some wastewater being discharged before it is fully purified, which will also have a certain impact on the environment. Therefore, this paper proposes an integrated multi-stage treatment device for industrial wastewater. Utility Model Content

[0004] The technical problem this invention aims to solve is that current integrated treatment equipment can only drive the wastewater forward continuously, resulting in some wastewater being discharged before it is fully purified, which can have a certain impact on the environment. This invention provides an integrated multi-stage industrial wastewater treatment device that can perform secondary purification by recirculation, ensuring effective and thorough purification of wastewater and preventing the discharged water from impacting the environment.

[0005] The technical solution adopted by this utility model to solve the technical problem is: an integrated multi-stage treatment device for industrial wastewater, including a treatment tank, a water collection tank is provided inside the treatment tank near one end, a partition plate is fixedly connected inside the treatment tank, the partition plate has a king-shaped structure, water pipes are inserted and connected through the partition plate, a pump box is detachably connected to one side of the outer wall of the treatment tank, a water pump is detachably connected inside the pump box, and a water pipe is evenly connected to the inlet and outlet ends of the water pump, the treatment tank is divided into four areas by the partition plate: a first dosing tank, a second dosing tank, a first sedimentation tank, and a second sedimentation tank.

[0006] As a preferred technical solution of this utility model, the water pipe is in the shape of an L-shaped hook. One end of the water pipe extends through the middle side wall of the partition plate into the No. 1 sedimentation tank. Four suction ports are evenly opened on the side wall of the end of the water pipe in the No. 1 sedimentation tank. The other end of the water pipe extends into the No. 2 dosing tank. Both sections of the water pipe are above the No. 1 sedimentation tank and the No. 2 dosing tank. There is a height difference between the partition plate itself.

[0007] As a preferred embodiment of this utility model, the top of the processing box is detachably connected to a cover plate, the top side wall of the cover plate is detachably connected to a mixing tank, and the top side wall of the mixing tank and near one edge are detachably connected to a vacuum feeder.

[0008] As a preferred technical solution of this utility model, a motor is detachably embedded in the middle of the top side wall of the mixing tank, and a stirring shaft is detachably connected to the output end of the motor. The stirring shaft has a U-shaped structure, and a feed inlet is provided through the top side wall of the mixing tank. The feed inlet is connected to the output port of the vacuum feeder.

[0009] As a preferred embodiment of this utility model, an output pipe is fixedly connected to the middle of the bottom side wall of the mixing tank. The output pipe is inserted and connected to the cover plate. Feeding pipes are fixedly connected to both side walls of the end of the output pipe that passes through the cover plate. The feeding pipe has an L-shaped structure and the transverse section of the feeding pipe is inclined downward.

[0011] The present invention has the following advantages: the pump box is started to pump out the sewage that has been treated once through one section of the water pipe, and then the sewage is sent into the No. 2 dosing tank through another section of the water pipe. The sewage in the No. 2 dosing tank will undergo secondary treatment and purification before being sent into the No. 2 sedimentation tank and finally into the clear water tank. This achieves the effect of secondary circulation treatment and ensures effective purification of sewage.

[0012] The purification chemicals can be added to the No. 1 and No. 2 dosing tanks through the output and feeding pipes to purify the wastewater in the No. 1 and No. 2 dosing tanks. Since the wastewater in the No. 2 dosing tank requires secondary treatment, the amount of chemicals added can be adjusted to avoid the negative effects of excessive chemicals.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 This utility model discloses an integrated multi-stage industrial wastewater treatment device, including a treatment tank 1. A water collection tank 2 is provided inside the treatment tank 1 near one end. A partition plate 3 is fixedly connected inside the treatment tank 1. The partition plate 3 has a king-shaped structure. A water pipe 9 is inserted through the partition plate 3. A pump box 10 is detachably connected to one side of the outer wall of the treatment tank 1. A water pump is detachably connected inside the pump box 10. A water pipe 9 is evenly connected to the inlet and outlet ends of the water pump. The treatment tank 1 is divided into four areas by the partition plate 3: a first dosing tank 4, a second dosing tank 5, a first sedimentation tank 6, and a second sedimentation tank 7.

[0019] The water pipe 9 has an L-shaped hook structure. One end of the water pipe 9 passes through the middle side wall of the partition plate 3 and extends into the No. 1 sedimentation tank 6. The side wall of the end of the water pipe 9 in the No. 1 sedimentation tank 6 is evenly provided with four suction ports 14. The other end of the water pipe 9 extends into the No. 2 dosing tank 5. Both sections of the water pipe 9 are above the No. 1 sedimentation tank 6 and the No. 2 dosing tank 5. There is a height difference between the partition plate 3 itself.

[0020] The technical effect of this solution is as follows: wastewater is injected into the collection tank 2, and as the water level rises, the wastewater enters the first dosing tank 4. After being purified by the chemicals in the first dosing tank 4, the wastewater enters the first sedimentation tank 6, where it settles. The pump box 10 is started to pump out the wastewater that has undergone primary treatment in the first sedimentation tank 6 through the corresponding water pipe 9 and the suction port 14 opened on it, and then sends it into the second dosing tank 5. The wastewater entering the second dosing tank 5 will be purified by adding chemicals for a second time, thus achieving the effect of double purification through reflux. Then, the wastewater that has undergone secondary purification in the second dosing tank 5 will enter the second sedimentation tank 7 for secondary sedimentation. Finally, the settled water will enter the clear water tank 8 for storage and discharge.

[0021] The top of the processing tank 1 is detachably connected to a cover plate 11. A mixing tank 12 is detachably connected to the top side wall of the cover plate 11. A vacuum feeder 13 is detachably connected to the top side wall of the mixing tank 12, near one edge. A motor 16 is detachably embedded in the middle of the top side wall inside the mixing tank 12. A stirring shaft 17 is detachably connected to the output end of the motor 16. The stirring shaft 17 has a U-shaped structure. A feed inlet 15 is provided through the top side wall of the mixing tank 12, communicating with the output port of the vacuum feeder 13. A [missing information - likely a device or component] is fixedly connected to the middle of the bottom side wall of the mixing tank 12. The output pipe 18 is inserted and connected to the cover plate 11. The two side walls of the end of the output pipe 18 that passes through the cover plate 11 are fixedly connected to the feeding pipe 20. The feeding pipe 20 has an L-shaped structure and the transverse section of the feeding pipe 20 is inclined downward. The bottom side wall of the output pipe 18 is fixedly connected to a cone-shaped diverter plate 19. The output pipe 18 is divided into two spaces by the diverter plate 19, and the two spaces are different in size. A clear water tank 8 is opened in the treatment box 1 at the end away from the water collection tank 2. The two ends of the treatment box 1 that are far away from each other are fixedly connected to the inlet and outlet water ports, and the inlet and outlet water ports are connected to the pump.

[0022] The technical effect of this solution is as follows: the starting motor 16 drives the stirring shaft 17 to rotate, thereby mixing the agent. A valve is connected to the output pipe 18. When it is needed to add the agent, the valve is opened and the agent enters the output pipe 18. Then, it is divided into two feeding pipes 20 by the diversion plate 19. Because the distance between the diversion plate 19 and the two feeding pipes 20 is different, the feed amount of the two feeding pipes 20 is different, thus adapting to the purification needs of the first feeding tank 4 and the second feeding tank 5.

[0023] Specifically, in use, wastewater is fed into the treatment tank 1 and accumulates in the collection tank 2. As the water level rises, the wastewater flows from the lower side wall of the partition plate 3 into the first dosing tank 4. Before this, the required purification agent is sent into the first dosing tank 4 through the output pipe 18 to purify the wastewater entering the first dosing tank 4. As the water level in the first dosing tank 4 rises, the water is sent into the first sedimentation tank 6 in the same way as before. When the water level in the first sedimentation tank 6 rises and covers the water pipe 9, the pump box 10 is started to extract the wastewater through the suction port 14. Then, the wastewater is sent into the second dosing tank 5 through another water pipe 9. After that, the corresponding amount of agent is added into the second dosing tank 5 through another feeding pipe 20 for secondary purification. Then, the wastewater in the second dosing tank 5 enters the second sedimentation tank 7 and finally flows from the second sedimentation tank 7 into the clear water tank 8, and is then pumped out and discharged.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
