Description

Technical Field

[0001] This utility model relates to the field of filter components technology, and in particular to a polyacrylamide graded filter screen. Background Technology

[0002] Flocculant sedimentation is a common method for treating industrial wastewater. By adding flocculants, suspended solids and chemical and biological oxygen-consuming substances are removed, thus purifying the wastewater. Polymer flocculants are divided into three categories: inorganic, natural, and synthetic. Among them, polyacrylamide is a commonly used synthetic flocculant in water treatment. It has various physical forms and is widely used in many industries due to its low dosage, high efficiency, and wide applicability.

[0003] A search revealed Chinese patent publication number CN220991801U, which discloses a polyacrylamide grading filter screen, including a screen plate and assembly components. The screen plate has multiple filter meshes and is divided into a first screen plate and a second screen plate. Side plates are integrally formed on both sides of the screen plate. The assembly components are multi-stage assembly grooves with side slots. For multi-stage filtration of polyacrylamide, the screen plates are used, relying on the first and second screen plates for grading and ensuring filtration efficiency. The multi-stage assembly groove allows for screen plate height adjustment to meet the needs of screen plates at different heights. However, during the sieving process, the sieve plates inside the equipment may accumulate, reducing the sieving efficiency. Therefore, this polyacrylamide grading filter screen is proposed to address this problem. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a polyacrylamide grading filter screen, which aims to improve the problem that the screening plates inside the equipment in the prior art will accumulate, reducing the material screening effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a polyacrylamide grading filter screen, comprising a screening tank, a sealing cover, and a screening plate. A servo motor is fixedly connected to the bottom of the screening tank. The output end of the servo motor passes through the bottom of the screening tank and is fixedly connected to a connecting column. A rotating rod is slidably connected to the top of the connecting column. Assembly grooves are formed around the outer wall of the rotating rod. An installation cylinder is slidably connected to the outer wall of the rotating rod. Scrapers are fixedly connected around the outer wall of the installation cylinder. A spring is fixedly connected to the top of the installation cylinder. The sealing cover... A rotating component is rotatably connected to the inner side of the rotating rod. A screw is fixedly connected to the top of the rotating rod. A reinforcing nut is threaded onto the outer wall of the screw. Engaging grooves are provided around the top of the screening tank. Adjusting plates are fixedly connected to the inner sides of multiple engagement grooves. Screening plates are fixedly connected between multiple adjusting plates. Multiple screw holes are provided around the outer wall of the screening tank. Bolts are threaded onto the inner sides of multiple screw holes. One adjacent end of each bolt penetrates the outer wall of the adjusting plate and is threaded onto the outer wall of the screening plate. A dispersing mechanism is provided on the left side of the outer wall of the screening tank.

[0006] The above technical solution involves installing the screening plates via a rotating shaft, and adjusting the distance between the screening plates using bolts and adjusting plates around the perimeter. Simultaneously, the screening plates and mounting cylinder are sequentially mounted on a rotating rod, with a rotating component passing through the top of the rod and reinforced with a reinforcing nut. A spring at the top of the mounting cylinder ensures the scraper on the outer wall fits tightly against the top of the screening plates. Activating the servo motor drives the scraper to clear any blockages in the material at the top of the screening plates. This detachable design not only facilitates free adjustment of the spacing between the screening plates but also prevents material blockage and improves screening efficiency.

[0007] As a further description of the above technical solution:

[0008] The dispersing mechanism includes a feed box, which is connected to the left side of the outer wall of the screening tank. A vibration motor is fixedly connected to the left side of the feed box. A dispersing frame is slidably connected to the inner side of the feed box. Mounting plates are fixedly connected to the front and rear ends of the top of the dispersing frame. Connecting bolts are threaded to the top of the two mounting plates. The bottom ends of the two connecting bolts penetrate the top of the mounting plates and are threaded to a fixing plate.

[0009] Through the above technical solution: large particles of material enter the screening tank through the feed box. When entering the screening tank, the large particles of material first pass through the dispersing rack. The dispersing rack, together with the vibrating motor, disperses the adhered and concentrated materials, so that the materials flow evenly into the screening plate and improve the screening accuracy.

[0010] As a further description of the above technical solution:

[0011] The outer walls of the sealing cover are all fixedly connected with buckles, and the outer walls of the screening tank are all fixedly connected with fasteners.

[0012] The above technical solution involves the interlocking of the buckle and the fixing component, followed by pressing the fixing component downwards to secure the sealing cover and improve its sealing performance.

[0013] As a further description of the above technical solution:

[0014] The top left and right ends of the sealing cap are fixedly connected to handles, and the outer wall of the handles is fixedly connected to anti-slip sleeves.

[0015] The above technical solution allows the sealing cap to be operated via a handle, making it easy to pick up.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the screening tank is fixedly connected to a support frame, and the bottom of the multiple support frames is fixedly connected to a rubber pad.

[0018] The above technical solution involves supporting the entire device with a support frame, and the use of rubber pads ensures the stability of the device.

[0019] As a further description of the above technical solution:

[0020] Each of the support frames has a reinforcing plate fixedly connected to its outer wall, and each of the reinforcing plates has an adjacent side fixedly connected to the outer wall of the screening tank.

[0021] The above technical solution involves reinforcing the support frame with reinforcing plates to ensure its service life.

[0022] As a further description of the above technical solution:

[0023] A controller is fixedly connected to the front side of the support frame, and the controller is electrically connected to the vibration motor and the servo motor respectively.

[0024] The above technical solution allows for convenient and simple operation and control of the operating equipment throughout the entire device via a controller.

[0025] As a further description of the above technical solution:

[0026] The bottom of the controller is fixedly connected to a mounting frame, and the bottom of the screening tank is connected to a discharge pipe.

[0027] The above technical solution uses a fixed frame for support to ensure the stability of the controller.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the inner shape of the mounting cylinder fits into the assembly groove. The mounting cylinder and the screening plate are installed in sequence, and the screw is connected to the sealing cover and the reinforcing nut. The screening plate is freely adjustable by the adjustment plates around it. The adjustment plates and the screening plate are reinforced by passing the bolts through the screw holes. The spring is installed at the top of the mounting cylinder.
