Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a scum collection device for biological pools in wastewater treatment plants. Background Technology

[0002] The main function of biological tanks in wastewater treatment plants is to degrade organic matter so that the treated wastewater can meet discharge standards. They utilize microorganisms to absorb harmful substances such as heavy metal ions and eutrophic substances in wastewater, making the wastewater cleaner and accelerating wastewater purification.

[0003] Currently, there is a lot of scum in the sewage in the biological tanks of sewage treatment plants. In order to avoid the scum from interfering with the subsequent biological treatment system, it is necessary to clean and collect the scum. Existing biological tanks usually use manual labor to regularly remove the scum, but the cleaning effect is not good. It is easy to have untimely or insufficient cleaning. At the same time, the cleaning process is time-consuming and labor-intensive, with low efficiency and certain safety hazards.

[0004] Therefore, in view of the problems that the above-mentioned manual regular removal of scum is not effective, and that the cleaning process is time-consuming, labor-intensive, inefficient, and poses certain safety hazards, a scum collection device for the biological tank of sewage treatment plant can be designed. By adding an automatic scum collection structure to the biological tank, the cleaning efficiency and effect can be improved instead of manual cleaning. Utility Model Content

[0005] In order to overcome the problems that manual regular scum removal is not effective, and that the cleaning process is time-consuming, labor-intensive, inefficient, and poses certain safety hazards.

[0006] The technical solution of this utility model is as follows: a scum collection device for a biological tank in a sewage treatment plant, comprising a biological tank body, support seats fixedly installed on the front and rear sides of the upper end of the biological tank body, a sprocket one and a sprocket two arranged on the side of the two support seats that are close to each other, a chain arranged on the outer side of the sprocket one and the sprocket two, a mesh plate arranged between the two support seats, a scum discharge bin arranged on the right side of the upper end of the biological tank body, an electric telescopic rod arranged at the upper end of the scum discharge bin, a scooping net arranged below the scum discharge bin, a spiral blade arranged on the inner side of the scum discharge bin, and a scum discharge port connected to the front end of the scum discharge bin.

[0007] Preferably, there are two sprockets arranged symmetrically front and back. A drive motor is fixedly installed on the side of the two support bases that are far apart from each other. The output end of the drive motor extends to the side of the support bases that are close to each other and is fixedly connected to the sprockets.

[0008] Preferably, there are two sprockets arranged symmetrically front and back and rotatably connected to the surface of the support base, and two chains arranged symmetrically front and back and drively connected to the outer sides of sprockets one and two.

[0009] Preferably, the inner sides of the mesh plate and the biological pool body are adapted to each other, a counterweight is fixedly installed at the lower end of the mesh plate, and the upper ends of the front and rear sides of the mesh plate are rotatably connected to the sides of the chain.

[0010] Preferably, the lower end of the slag discharge bin has an open structure design. The front and rear sides of the lower end of the slag discharge bin and the upper end of the biological tank body are fixedly connected by support plates. The side of the two support plates that are close to each other, the front and rear sides of the inner wall of the slag discharge bin and the front and rear sides of the inner wall of the biological tank body are all on the same plane.

[0011] Preferably, the electric telescopic rod is fixedly connected to the upper end of the slag discharge bin, the output end of the electric telescopic rod extends to the lower end of the slag discharge bin and is fixedly connected to the upper side of the retrieval net, and the retrieval net is adapted to the right end of the inner side of the biological pool.

[0012] As a preferred embodiment, the lower end of the dredging net is designed with an arc shape, and the spiral blades are adapted to the lower end of the inner side of the dredging net. A second drive motor is fixedly installed on the rear side of the slag discharge bin.

The front end of the spiral blades extends to the inner side of the slag discharge port and is adapted to the inner side of the slag discharge port.

[0013] The beneficial effects of this utility model are:

[0014] This scum collection equipment for the biological tank of the wastewater treatment plant uses a drive motor to rotate a chain, and a counterweight keeps the screen plate hanging downwards. This causes the screen plate to sweep across the wastewater surface, repeatedly pushing the scum to the bottom of the right-side scum discharge bin, achieving rapid collection of the scum. An electric telescopic rod then lifts the scooping net, scooping the scum into the discharge bin. By attaching the spiral blades to the scooping net, a second drive motor rotates the spiral blades, discharging the scum from the surface of the scooping net towards the discharge port. This system effectively cleans the scooping net and collects the scum, making the process convenient, fast, and improving scum collection efficiency. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a scum collection device for a biological tank in a sewage treatment plant, comprising a biological tank body 1, support seats 2 fixedly installed on the front and rear sides of the upper end of the biological tank body 1, a sprocket 3 and a sprocket 4 arranged on the side of the two support seats 2 that are close to each other, a chain 5 arranged on the outer side of the sprocket 3 and the sprocket 4, a mesh plate 6 arranged between the two support seats 2, a scum discharge bin 7 arranged on the right side of the upper end of the biological tank body 1, an electric telescopic rod 8 arranged on the upper end of the scum discharge bin 7, a scooping net 9 arranged below the scum discharge bin 7, a spiral blade 10 arranged on the inner side of the scum discharge bin 7, and a scum discharge port 11 connected to the front end of the scum discharge bin 7.

[0022] Please see Figures 1-2 In this embodiment, two sprockets 3 are arranged symmetrically front to back. A drive motor 31 is fixedly installed on the side of the two support seats 2 that are far apart from each other. The output end of the drive motor 31 extends to the side of the support seats 2 that are close to each other and is fixedly connected to the sprockets 3. Two sprockets 4 are arranged symmetrically front to back and are rotatably connected to the surface of the support seats 2. Two chains 5 are arranged symmetrically front to back and are drive-connected to the outer sides of the sprockets 3 and 4. The mesh plate 6 is adapted to the inner side of the biological pool body 1. A counterweight 61 is fixedly installed at the lower end of the screen plate 6. The upper ends of the front and rear sides of the screen plate 6 are rotatably connected to the side of the chain 5. The drive motor 31 drives the two sprockets 3 to rotate simultaneously. At this time, the sprocket 4 rotates in coordination, driving the chain 5 to rotate. The counterweight 61 keeps the screen plate 6 hanging downward, so that after the screen plate 6 sweeps across the sewage surface, it rises with the chain 5 at the sprocket 4 and then returns to the sprocket 3. This repeatedly pushes the scum on the sewage surface to the bottom of the right scum discharge bin 7, achieving rapid collection of scum.

[0023] Please see Figures 3-4In this embodiment, the lower end of the slag discharge bin 7 has an open structure design. The front and rear sides of the lower end of the slag discharge bin 7 and the upper end of the biological pool body 1 are fixedly connected by support plates 71. The sides of the two support plates 71 that are close to each other, the front and rear sides of the inner wall of the slag discharge bin 7, and the front and rear sides of the inner wall of the biological pool body 1 are all on the same plane. The electric telescopic rod 8 is fixedly connected to the upper end of the slag discharge bin 7. The output end of the electric telescopic rod 8 extends to the lower end of the slag discharge bin 7 and is fixedly connected to the upper side of the retrieval net 9. The retrieval net 9 and the right end of the inner side of the biological pool body 1 are mutually adapted. The lower end of the retrieval net 9 has an arc-shaped structure design. The spiral blade 10 and the lower end of the inner side of the retrieval net 9 are mutually adapted. Slag discharge A drive motor 2 101 is fixedly installed on the rear side of the slag discharge bin 7. The output end of the drive motor 2 101 extends to the inner side of the slag discharge bin 7 and is fixedly connected to the rear end of the spiral blade 10. The front end of the spiral blade 10 extends to the inner side of the slag discharge port 11 and is adapted to the inner side of the slag discharge port 11. After the scum is concentrated on the right side, the electric telescopic rod 8 drives the scooping net 9 to rise and scoop the scum into the slag discharge bin 7. By attaching the spiral blade 10 to the scooping net 9, the drive motor 2 101 drives the spiral blade 10 to rotate, and outputs the scum on the surface of the scooping net 9 to the slag discharge port 11, thereby cleaning the scooping net 9 and collecting the scum, while facilitating the next round of scooping.

[0024] During operation, the drive motor 31 drives two sprockets 3 to rotate simultaneously. At the same time, the sprocket 4 rotates in coordination, driving the chain 5 to rotate. The counterweight 61 keeps the screen plate 6 hanging downwards, so that after the screen plate 6 sweeps across the sewage surface, it rises off the water surface at the sprocket 4 with the chain 5 and then returns to the sprocket 3. This repeatedly pushes the scum on the sewage surface to the bottom of the right-side scum discharge bin 7, achieving rapid collection of the scum. After the scum is collected on the right side, the electric telescopic rod 8 drives the scooping net 9 to rise, scooping the scum into the scum discharge bin 7. By attaching the spiral blades 10 to the scooping net 9, the drive motor 101 drives the spiral blades 10 to rotate, outputting the scum on the surface of the scooping net 9 to the scum discharge port 11, thus cleaning the scooping net 9 and collecting the scum, while facilitating the next round of scooping.

[0025] Through the above steps, the mesh plate 6 sweeps across the surface of the sewage, repeatedly pushing the scum on the surface of the sewage to the bottom of the right-side scum discharge bin 7. The electric telescopic rod 8 drives the scooping net 9 to rise, scooping the scum into the scum discharge bin 7. The drive motor 101 drives the spiral blades 10 to rotate, outputting the scum on the surface of the scooping net 9 to the scum discharge port 11. This solves the problems of poor results from manual regular scum removal, which is time-consuming, labor-intensive, inefficient, and poses certain safety hazards.
