Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing technology, specifically to a portable assembly device for a filter screen at the sedimentation tank of a mineral processing plant. Background Technology
[0002] In the mineral processing industry, sedimentation tanks are an essential part of the wastewater treatment process. Sedimentation tanks purify water by utilizing the principle that suspended impurities in the water flow separate from the water when the downward settling velocity is greater than the upward flow velocity, or the downward settling time is less than the time it takes for the water to flow out of the sedimentation tank. The treatment efficiency of an ideal sedimentation tank is only related to its surface load, i.e., its surface area, and not its depth. The depth of the tank is only related to the storage time and quantity of sludge and factors preventing sludge erosion. However, in actual continuously operating sedimentation tanks, the overflow from the effluent weir creates an upward flow velocity. Therefore, particles with a settling velocity less than the upward flow velocity are carried away by the water flow. To address this, a filter device—a grate—is often installed at the overflow outlet. However, since mineral processing wastewater is corrosive, traditional grates are often quite thick and heavy, making replacement or maintenance difficult and extraction challenging for personnel. Utility Model Content
[0003] This invention provides a portable assembly device for the filter screen of the sedimentation tank in a mineral processing plant, in order to solve the problems mentioned above.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A portable assembly device for a filter screen at the sedimentation tank of a mineral processing plant includes an inner telescopic beam, an outer telescopic beam movably mounted on the inner telescopic beam, multiple hooks fixedly mounted on the outer side of the outer telescopic beam, and a filter screen detachably mounted on the bottom of the outer telescopic beam.
[0005] Furthermore, a handle is fixedly provided on the top of the outer telescopic beam.
[0006] This utility model has the following beneficial effects: This utility model provides a portable assembly device for the filter screen of a sedimentation tank in a mineral processing plant. It mainly includes a handle, hook, a retractable inner telescopic beam, an outer telescopic beam, and a filter screen. By connecting the retractable inner and outer telescopic beams to the cement side of the sedimentation tank and then connecting the retractable inner and outer telescopic beams to the filter screen, the inner and outer telescopic beams and the filter screen can extend and retract according to actual size requirements. The main body of the device is made of stainless steel, which effectively prevents corrosion from acids and alkalis, adapting to the application environment. The retractable structure of the inner and outer telescopic beams and the filter screen effectively reduces the frequency of replacement and assembly. Furthermore, the assembly device is directly installed on the cement, greatly simplifying the operation process and solving the common problem of time-consuming and labor-intensive disassembly and replacement of filter screens in sedimentation tanks of mineral processing plants, which affects filtration efficiency.

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0012] like Figure 1-3 As shown, a portable assembly device for a filter screen of a sedimentation tank in a mineral processing plant includes an inner telescopic beam 3, an outer telescopic beam 4 movably mounted on the inner telescopic beam 3, a plurality of hooks 2 fixedly mounted on the outer side of the outer telescopic beam 4, and a filter screen 5 detachably mounted on the bottom of the outer telescopic beam 4.
[0013] A handle 1 is also fixedly installed on the top of the outer telescopic crossbeam 4.
[0014] The inner telescopic beam 3 and the outer telescopic beam 4 are movably connected, allowing them to extend and retract freely when not in use or when the filter bed is short, thus reducing the space occupied.
[0015] The main structure of the assembly device is made of stainless steel, which is resistant to acids and alkalis and has high strength.
[0016] The inner telescopic beam 3 and the outer telescopic beam 4 of the telescopic structure of the assembly device both adopt a concave-convex structure, which reduces the manufacturing process and saves manufacturing costs.
[0017] In practical application, firstly, install a fixing clip on the side of the filter in the sedimentation tank, and pull the inner telescopic beam 3 and the outer telescopic beam 4 according to the length requirements. Then, use a fixing pin to connect the hook 2 to the fixing clip on the side of the filter in the sedimentation tank, and install the extraction handle 1 properly. Finally, place the filter screen 5 in the filtrate. The entire installation and assembly process effectively reduces the frequency of replacing and assembling the filter screen 5. Moreover, this assembly device is directly installed on cement, which greatly simplifies the operation process and solves the common problem of time-consuming and laborious disassembly and replacement of filter screen 5 in the sedimentation tank of mineral processing plants, which affects filtration efficiency. Therefore, this device has good practicality.
