Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal equipment, in particular to an impurity removal device for chromium-free passivator. Background Art

[0002] Passivation refers to the process in which a metal is oxidized by a strong oxidant or an electrochemical method to make the surface become an inactive state, that is, the passivation process. It is a method to make the metal surface transform into a state that is not easily oxidized and delay the corrosion rate of the metal. In addition, the phenomenon that an active metal or alloy has its chemical activity greatly reduced and becomes a noble metal state is also called passivation. A chromium-free passivator is a passivator without chromium. In order to reduce the emission of the chromium-free passivator during use, it is usually collected, purified and then reused.

[0003] However, the existing impurity removal equipment is prone to blockage of the filter screen, which requires relevant personnel to frequently shut down the machine and deal with the blocked filter screen, thus reducing the processing efficiency of the equipment. Therefore, an impurity removal device for chromium-free passivator is proposed. Summary of the Utility Model

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

[0011] The extrusion structure includes a motor fixedly installed on one side of the processing box, a first rotating shaft and a second rotating shaft movably installed on the inner wall of the processing box. One ends of the first rotating shaft and the second rotating shaft both extend outside the processing box, and a first pulley and a second pulley are respectively fixedly sleeved on the first rotating shaft and the second rotating shaft. The first pulley and the second pulley are sleeved with the same belt. The output end of the motor is fixedly connected to one end of the first rotating shaft. Two mounting blocks are fixedly arranged on both the first rotating shaft and the second rotating shaft, and ejector rods are fixedly arranged on all four mounting blocks.

[0012] As a further description of the above technical solution:

[0013] The pressing structure includes sliding rods fixedly installed in each mounting groove. Sliding blocks are movably arranged on both sliding rods.

The motor drives the two rotating shafts to rotate, the rotating shafts drive the mounting blocks, and the mounting blocks drive the ejector rods to extrude the mounting frame. The top of the mounting frame then extrudes the first spring. When the ejector rod disengages from the contact with the mounting frame, the first spring pushes the mounting frame downward, enabling the mounting frame and the filter plate to be in a vibrating state, preventing impurities in the passivator from clogging the filter holes of the filter plate during filtration and impurity removal, ensuring the normal operation of the equipment, eliminating the need for relevant personnel to frequently clean the filter screen, and ensuring the processing efficiency of the equipment.

Compared with the prior art, in this chromium-free passivator impurity removal device, by setting the sliding rods, the sliding blocks, the second spring, the pressing plate, the limiting grooves and the limiting blocks, when the filter plate needs to be replaced, the top cover on the top of the processing box is removed, and then multiple pressing plates are pulled in a direction away from the filter plate. The pressing plates drive the sliding blocks to move on the sliding rods. When the rubber pad at the bottom of the pressing plate disengages from the contact with the limiting block, the filter plate is pulled upward, and the disassembly of the filter plate can be completed, facilitating subsequent replacement.
