Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment devices, and in particular to a suspended packing interception device for a sewage treatment biochemical tank. Background Technology

[0002] Currently, rectangular stainless steel mesh is commonly used in biological treatment tanks for wastewater treatment to intercept suspended media from MBBR and CFBR processes, preventing them from entering the next process stage with the effluent. However, traditional rectangular mesh is simply a rectangular stainless steel plate placed at the outlet of the biological treatment tank. It only has an interception function; the media is intercepted and accumulates here, achieving only the interception effect but not the separation of the media. The media accumulates higher and higher, eventually overflowing the top of the tank and causing media loss. Furthermore, stainless steel is prone to wear and cracking after long-term impact from the media, with a service life typically less than two years, requiring frequent replacement and resulting in high maintenance costs. Stainless steel also has poor wear resistance, is easily damaged, and has a short service life. Moreover, its simple structure cannot actively remove accumulated media, relying on manual cleaning, which is inefficient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a suspended packing interception device for sewage treatment biochemical ponds that has the functions of packing separation and anti-accumulation, doubles the life of the screen, and greatly reduces the loss of packing.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a suspended filler interception device for a biological treatment tank in sewage treatment, comprising a fan-shaped mounting plate at the top, a drive motor fixedly mounted on the upper part of the fan-shaped mounting plate, a transmission shaft mounted below the axis of the fan-shaped mounting plate, the power output end of the drive motor being fixedly connected to the transmission shaft, an interception net being installed around the arc edge of the fan-shaped mounting plate extending along the direction of the transmission shaft, and a cylinder wall cleaning device being spirally mounted on the transmission shaft, the cylinder wall cleaning device being in contact with the inner wall of the interception net.

[0005] As a preferred technical solution, the central angle of the fan-shaped mounting plate is 100° to 180°.

[0006] As a preferred technical solution, the cylinder wall cleaning device includes a plurality of support rods arranged in a spiral pattern and mounted on the drive shaft. Each support rod is horizontally arranged and has a consistent length. A spiral side clamp is installed at the end of the support rod, and a brush is detachably mounted on the side clamp.

[0007] As a preferred technical solution, the support rod is a cylindrical rod, the diameter of the support rod is smaller than the diameter of the transmission shaft, and the vertical spacing of each support rod is equal.

[0008] As a preferred technical solution, the spacing between two adjacent support rods is kept consistent.

[0009] As a preferred technical solution, the side clamp and the brush are detachably connected by bolts.

[0010] As a preferred technical solution, the interception network is a UPE network.

[0011] As a preferred technical solution, the interception net is a double-layer net, with the two layers of net being fixedly connected by a fastening device, and a limiting block is provided between the two layers of net to ensure that the distance between the two layers of net remains unchanged.

[0012] The above-mentioned technical solution provides a suspended filler interception device for a wastewater treatment biochemical tank. It includes a fan-shaped mounting plate at the top, a drive motor fixedly mounted on the upper part of the fan-shaped mounting plate, and a transmission shaft mounted below the axis of the fan-shaped mounting plate. The power output end of the drive motor is fixedly connected to the transmission shaft. An interception net is installed around the arc edge of the fan-shaped mounting plate, extending along the direction of the transmission shaft. A cylinder wall cleaning device is spirally mounted on the transmission shaft, fitting snugly against the inner wall of the interception net. The beneficial effects of this invention are: when installed at the outlet of the biochemical tank, the water in the biochemical tank enters from the concave side of the interception net, is intercepted by the net, and flows out from the convex side. The suspended filler is intercepted on one side of the concave side of the interception net. The drive motor drives the transmission shaft to rotate, which in turn drives the cylinder wall cleaning device connected to it to rotate, spirally cleaning the inner wall of the interception net and rotating and throwing out the accumulated suspended filler, which then returns to the inside of the biochemical tank. The material of the net is changed from stainless steel to UPE wear-resistant material, which has five times the wear resistance of stainless steel, greatly extending its lifespan. Upgrading the structure and materials prevents packing material accumulation. This invention uses a semi-cylindrical interceptor mesh combined with a wall cleaning device to achieve dynamic separation and recirculation of suspended packing material, avoiding its accumulation and loss. This invention operates automatically, eliminating the need for manual cleaning and reducing maintenance costs. Its compact structure and highly adaptable interceptor mesh design make it suitable for various wastewater treatment processes (such as MBBR and CFBR). The integrated drive and transmission system achieves integrated interception, separation, and recirculation functions. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0016] like Figures 1 to 3 As shown, a suspended filler interception device for a biological wastewater treatment tank includes a fan-shaped mounting plate 1 at the top, a drive motor 2 fixedly mounted on the upper part of the fan-shaped mounting plate 1, a transmission shaft 3 mounted below the axis of the fan-shaped mounting plate 1, the power output end of the drive motor 2 fixedly connected to the transmission shaft 3, an interception net 4 extending along the direction of the transmission shaft 3 around the arc edge of the fan-shaped mounting plate 1, and a cylinder wall cleaning device 5 spirally mounted on the transmission shaft 3, the cylinder wall cleaning device 5 fitting against the inner wall of the interception net 4; this utility model is installed... At the outlet of the biological treatment tank, water flows into the tank through the concave side of the interceptor net 4, and flows out through the convex side after being intercepted by the net 4. The suspended filler is trapped on the concave side of the net 4. The drive motor 2 drives the transmission shaft 3 to rotate, which in turn drives the connected cylinder wall cleaning device 5 to rotate, spirally cleaning the inner wall of the net 4 and throwing out the accumulated suspended filler, which then returns to the inside of the biological treatment tank. The material of the net 4 has been changed from stainless steel to UPE wear-resistant material, which has five times the wear resistance of stainless steel, greatly extending its service life. After upgrading the structure and materials, the accumulation of filler is avoided. This utility model uses a semi-cylindrical structure of the net 4 in conjunction with the cylinder wall cleaning device 5 to achieve dynamic separation and return of the suspended filler, avoiding its accumulation and loss. This utility model operates automatically, requiring no manual cleaning, reducing maintenance costs. The structure is compact: the design of the net 4 is highly adaptable and suitable for various wastewater treatment processes (such as MBBR and CFBR). The overall structure integrates the drive and transmission system, realizing the integrated function of interception, separation, and return.

[0017] like Figure 1 and Figure 3As shown, the central angle of the fan-shaped mounting plate 1 is 100° to 180°, preferably 150°, which not only facilitates installation and provides a sufficiently large interception area but also ensures good interception effect. In use, several of these devices are arranged at the water outlet, and the water flows from the concave surface of the interception net 4 to the convex surface, as... Figure 1 The direction indicated by the middle arrow is the direction of water flow.

[0018] like Figures 1 to 3 As shown, the cylinder wall cleaning device 5 includes several support rods 51 arranged in a spiral pattern and mounted on the drive shaft 3. Each support rod 51 is horizontally positioned and has a consistent length. A spiral-shaped clamp 52 is attached to the end of each support rod 51, and a brush 53 is detachably mounted on the clamp 52. The support rods 51 fix the spiral-shaped clamp 52 to the drive shaft 3, and the detachable brush 53 facilitates replacement and maintenance. The consistent length of the support rods 51 ensures that the brush 53 remains in close contact with the inner wall of the interceptor mesh 4, resulting in excellent cleaning performance.

[0019] like Figure 1 and Figure 2 As shown, the support rod 51 is a cylindrical rod, and the diameter of the support rod 51 is smaller than the diameter of the drive shaft 3. The vertical spacing of each support rod 51 is equal. Other shapes of support rods 51 are also possible, but cylindrical rods are easier to process, and the smaller diameter can save materials and reduce weight. In addition, they will not obstruct the suspended packing.

[0020] like Figure 1 and Figure 2 As shown, the spacing between two adjacent support rods 51 is consistent. The support rods 51 are arranged at equal intervals, ensuring the stability of the structure.

[0021] like Figure 1 and Figure 3 As shown, the side clamp 52 and the brush 53 are detachably connected by bolts 54. The side clamp 52 holds the brush 53 and fixes it in place by bolts 54. When replacement is needed, simply unscrew the bolts 54 and replace it with a new brush 53, which is convenient for maintenance and upkeep.

[0022] Interception net 4 is made of UPE mesh. This material is five times more wear-resistant than stainless steel, and with the upgraded structure and materials, the lifespan of the net is doubled.

[0023] like Figure 3 As shown, the interception net 4 is a double-layer net, with the two layers fixedly connected by a fastening device. A limiting block 6 is installed between the two layers to ensure that the spacing between them remains constant. The double-layer net provides double protection to prevent the loss of suspended filler material due to the rupture of one layer. Multiple layers would increase costs; two layers are the optimal technical solution.

[0024] This utility model has the following advantages: (1) Anti-accumulation design: The semi-cylindrical interception net 4, together with the drive shaft 3 and the cylinder wall cleaning device 5, realizes dynamic separation and reflux of suspended packing, avoiding accumulation and loss.

[0025] (2) Strong wear resistance: The UPE material used in the interception net 4 has five times the wear resistance of stainless steel, and its service life is extended to more than four years.

[0026] (3) Automated operation: The drive motor 2 drives the transmission shaft 3, eliminating the need for manual cleaning and reducing maintenance costs.

[0027] (4) Compact structure: It is suitable for a variety of wastewater treatment processes (such as MBBR and CFBR) and has strong adaptability.
