Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment device for metal smelting. Background Technology

[0002] Metal smelting is a fundamental industry of the national economy, encompassing core processes such as iron smelting, steelmaking, and non-ferrous metal extraction. During the smelting process, a large amount of water resources are consumed for cooling equipment, washing fumes, and leaching ores. The resulting wastewater has a complex composition and a high pollution load. If it is not properly treated and discharged directly, it will cause serious harm to the soil, water bodies, and ecological environment, and also threaten human health. Therefore, a wastewater treatment device for metal smelting is needed.

[0003] Existing wastewater treatment devices for metal smelting often suffer from clogged filtration mechanisms due to the inaccessibility and lack of visibility, making thorough cleaning of the internal components impossible. Traditional devices typically use bolts and flanges to directly fix the filter screens within the filter chamber, requiring wrenches and screwdrivers to disassemble each component. However, the harsh environment of smelting workshops makes bolts prone to rust and stripping, and improper tool selection often results in bolts being impossible to remove, forcing the use of cutting methods to damage the connectors and consequently the filter screens and filter chambers. Therefore, a new wastewater treatment device for metal smelting is urgently needed. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a wastewater treatment device for metal smelting, in order to solve the problem that existing wastewater treatment devices for metal smelting are prone to clogging and residue due to the inability to see or reach the filter mechanism during maintenance, making it impossible to thoroughly clean the inside of the filter mechanism. In traditional devices, the filter screen is often directly fixed in the filter chamber by bolts and flanges. Disassembly requires the use of wrenches, screwdrivers and other tools to disassemble the connecting parts one by one. However, the environment in the smelting workshop is harsh, and the bolts are prone to rust and stripping. Problems such as improper tool matching and inability to disassemble the bolts often occur, forcing the use of cutting methods to damage the connecting parts, resulting in damage to the filter screen and filter chamber.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device for metal smelting, comprising a tank, a cover plate fixedly connected to the top of the tank, an inlet provided at the top of the cover plate, an outlet provided at the bottom of the tank, a lead screw installed on the inner wall of the tank, a transmission handle provided at the bottom of the lead screw, a slider installed on the inner wall of the tank, a filter screen compartment provided on the side wall of the slider, a groove provided on the inner wall of the tank, and a guide plate provided on the outer wall of the groove.

[0006] The inner wall of the filter compartment has a slot, the inner wall of the slot is fixedly connected to a threaded rod, the outer wall of the threaded rod is fitted with a fixed handle, the inner wall of the filter compartment is fitted with a filter screen, and the side wall of the filter screen is provided with an insert block.

[0007] Preferably, the lead screw is movably connected to the tank body, and the lead screw forms a rotating structure with the tank body through a transmission handle.

[0009] Preferably, the sidewall of the slider is slotted, and the slider is engaged with the guide plate.

[0010] Preferably, the inner wall of the fixed handle is threaded, and the fixed handle is threadedly connected to the threaded rod.

[0011] Preferably, the filter screen forms a sliding structure through a plug and a slot, and the plug and slot are inserted into each other.

[0012] Preferably, the outer wall of the insert is slotted, and the insert is movably connected to the threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a lead screw, transmission handle, slider, filter screen compartment, slide groove and guide plate, allows the filter screen compartment to move upward by rotating the transmission handle and driving the lead screw to rotate until the slider moves to the end of the lead screw. It breaks through the traditional closed limit structure of the lead screw top and adopts an open top design to achieve quick separation of the slider and lead screw. The filter screen compartment can be removed without disassembling the transmission components, so that the inside of the filter screen compartment can be thoroughly cleaned. It avoids the blockage and residue caused by the "cannot see or reach" during the maintenance of the traditional tank. It realizes the convenient removal and maintenance of the filter screen compartment of the metal smelting wastewater treatment device, and takes into account the ease of operation, structural reliability and cost economy. 2. This utility model, through the design of a filter compartment, slot, threaded rod, fixed handle, filter screen, and insert block, allows for the removal of multiple filter screens installed in the filter compartment by rotating and removing the fixed handle that holds the filter screen, and then pulling the filter screen outward. This ensures that the filter screens can be cleaned or replaced in a timely manner, avoiding a decrease in filtration efficiency due to filter screen blockage or heavy metal leakage due to filter screen damage, ensuring stable and compliant effluent water quality. No auxiliary tools are required, significantly improving filter screen maintenance efficiency. It is especially suitable for scenarios involving high impurities in smelting wastewater that require frequent filter screen cleaning and replacement. Attached Figure Description
