Description

Technical Field

[0001] The utility model relates to the field of industrial wastewater treatment, and specifically, to a self-cleaning wastewater sedimentation treatment tank. Background Technique

[0002] Wastewater treatment is to use physical, chemical and biological methods to treat wastewater, purify the wastewater, reduce pollution, so as to achieve wastewater recycling and reuse, make full use of water resources. Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to the wastewater and waste liquid generated in the industrial production process, and contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Industrial wastewater has a wide variety and complex composition. Therefore, comprehensive utilization and turning harm into benefit should be developed. After taking corresponding purification measures for disposal according to the components and concentrations of pollutants in the wastewater, it can be discharged. There are various methods for treating industrial wastewater, and the widely used one is the sedimentation tank method. The sedimentation tank method is a common industrial wastewater treatment method. Through the natural settlement of suspended solids and dissolved pollutants in the wastewater, the pollutants are separated from the wastewater. This method can effectively remove suspended particles in the wastewater. For example, hydroxide precipitation method, sulfide precipitation method, reduction-precipitation method and flocculation flotation precipitation method, etc. In practical applications, the sedimentation method usually needs to be used in combination with other technologies to improve the treatment effect and reduce secondary pollution.

[0003] At present, the sedimentation tanks used for industrial wastewater treatment all add filters to filter the wastewater. After filtering large particles, the filters are cleaned manually. Manual cleaning is not only time-consuming and laborious, but also easy to cause harm to the human body. In view of this, we propose a self-cleaning wastewater sedimentation treatment tank. Content of the Utility Model

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Wastewater treatment is to use physical, chemical and biological methods to treat wastewater, purify the wastewater, reduce pollution, so as to achieve wastewater recycling and reuse, and make full use of water resources. Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to the wastewater and waste liquid generated in the industrial production process, and contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Industrial wastewater has a wide variety and complex composition. Since industrial wastewater often contains various toxic substances and pollutes the environment and poses a great harm to human health, it is necessary to develop comprehensive utilization and turn harm into benefit. After taking corresponding purification measures for disposal according to the components and concentrations of pollutants in the wastewater, it can be discharged. There are various methods for treating industrial wastewater, and the widely used one is the sedimentation tank method. The sedimentation tank method is a common industrial wastewater treatment method, which separates pollutants from the wastewater by the natural settlement of suspended solids and dissolved pollutants in the wastewater. This method can effectively remove suspended particles in the wastewater. For example, hydroxide precipitation method, sulfide precipitation method, reduction-precipitation method and flocculation flotation precipitation method, etc. In practical applications, the precipitation method usually needs to be used in combination with other technologies to improve the treatment effect and reduce secondary pollution. Please refer to Figures 1 - 4As shown in the figure, the utility model provides a self-cleaning wastewater sedimentation treatment tank, which includes a wastewater treatment tank 1. A clamping groove 11 is opened at the top of the rear side of the wastewater treatment tank 1. A lead screw 21 is rotatably connected in the clamping groove 11. One end of the lead screw 21 is fixedly connected to the top end of a second motor 2. A push block 22 is rotatably connected to the lead screw 21. A first filter screen 23 is fixedly connected to the inner wall of the wastewater treatment tank 1. The first filter screen 23 is located below the push block 22. A square groove 12 is opened in the middle of the wastewater treatment tank 1. The square groove 12 is located below the first filter screen 23. A plurality of water spray pipes 34 are placed in the square groove 12. The water spray pipes 34 are fixedly connected to a main pipe 35. The main pipe 35 is fixedly connected to the interface of a water pump 36. A water outlet 4 is fixedly connected to the front end of the wastewater treatment tank 1. A second filter screen 41 is fixedly connected inside the water outlet 4.

[0024] The improvement of the present utility model lies in:

[0025] Since the sedimentation tanks used for wastewater treatment in industry all increase filter screens to filter wastewater. After filtering out large particulate matters, the filter screens are then cleaned manually. Manual cleaning is not only time-consuming and laborious, but also easy to cause harm to the human body. Therefore, after filtering the wastewater, large particulate matters remain on the first filter screen 23. By starting the second motor 2, the second motor 2 rotates, driving the lead screw 21 to rotate, thereby pushing the push block 22 to move forward, pushing the large particulate matters on the surface of the first filter screen 23 to the discharge port 14, and falling into the waste collection tank 42 from the discharge port 14, completing the cleaning of the first filter screen 23. When the wastewater inside the wastewater treatment tank 1 is completely discharged from the water outlet 4, for the fine particulate matters remaining inside the wastewater treatment tank 1 and on the second filter screen 41, by starting the water pump 36, the water is pumped up, reaches the first high-pressure nozzle 37 and the second high-pressure nozzle 38 through the water spray pipes 34, and cleans the fine particulate matters remaining inside the wastewater treatment tank 1 and on the second filter screen 41.

[0026] Considering that the area inside the wastewater treatment tank 1 is relatively large, it is necessary to control and adjust the water outlet direction of the water spray pipes 34. Therefore, a support block 33 is fixedly connected below the water spray pipes 34. The other end of the support block 33 is fixedly connected to a push rod 32. Teeth are provided at the rear end of the push rod 32. The rear end of the push rod 32 meshes with a gear 31. The gear 31 is fixedly connected to the top end of a first motor 3. By controlling the forward and reverse rotation of the first motor 3, driving the forward and reverse rotation of the gear 31, thereby pushing the push rod 32 to move left and right, and then driving the water spray pipes 34 to move left and right, realizing the control of the water outlet direction of the water spray pipes 34.

[0027] In order to reduce the friction between the water spray pipe 34 and the square groove 12, a plurality of circular grooves 13 are provided in the square groove 12. A frustum 15 is rotatably connected in the groove 13. The top of the frustum 15 is fixedly connected to the water spray pipe 34. The water spray pipe 34 rotates left and right on the frustum 15, avoiding the contact between the water spray pipe 34 and the square groove 12, reducing friction, and thus protecting the water spray pipe 34.

[0028] Considering that the inside of the wastewater treatment tank 1 can be cleaned comprehensively, the front ends of adjacent water spray pipes 34 are respectively fixedly connected with a first high-pressure nozzle 37 and a second high-pressure nozzle 38. The opening of the first high-pressure nozzle 37 is at the front end, and the opening of the second high-pressure nozzle 38 is on the side. The water spraying directions of the first high-pressure nozzle 37 and the second high-pressure nozzle 38 are horizontal and vertical directions respectively, and the first high-pressure nozzle 37 and the second high-pressure nozzle 38 are staggered, greatly increasing the water spraying coverage area, so that the inside of the wastewater treatment tank 1 can be cleaned comprehensively.

[0029] In order to better clean the large particles on the surface of the first filter screen 23, the bottom of the push block 22 is of an "inclined surface" structure. The push block 22 does not contact the first filter screen 23. The inclined surface can increase the contact area between the push block 22 and the large particles, so as to better push the large particles and realize the cleaning of the large particles.

[0030] Considering that the waste can be better collected and processed, a discharge port 14 is provided on the side of the wastewater treatment tank 1. The discharge port 14 corresponds to the position of the first filter screen 23. A waste collection tank 42 is placed below the discharge port 14. When the push block 22 moves to the discharge port 14, the large particles fall into the waste collection tank 42 under the action of gravity, completing the collection and processing of the waste.

[0031] In summary, the working principle of this solution is as follows:

[0032] When treating wastewater, the wastewater passes through the first filter screen 23 for preliminary filtration. Large particulate matters will remain on the first filter screen 23. By starting the second motor 2, the second motor 2 rotates, driving the screw rod 21 to rotate, thereby pushing the push block 22 to move forward, pushing the large particulate matters on the surface of the first filter screen 23 to the discharge port 14, and falling into the waste collection tank 42 from the discharge port 14, completing the cleaning of the first filter screen 23. When the wastewater in the wastewater treatment tank 1 passes through the water outlet 4 and undergoes secondary filtration through the second filter screen 41, after the discharge is completed, for the fine particulate matters remaining inside the wastewater treatment tank 1 and on the second filter screen 41, by starting the water pump 36, the water is pumped up, reaches the first high-pressure nozzle 37 and the second high-pressure nozzle 38 through the water spray pipe 34. By controlling the forward and reverse rotation of the first motor 3, driving the forward and reverse rotation of the gear 31, thereby pushing the push rod 32 to move left and right, thereby driving the water spray pipe 34 to move left and right, realizing the control of the water outlet direction of the water spray pipe 34, and thus realizing the comprehensive cleaning of the inside of the wastewater treatment tank 1 and the second filter screen 41.
