Description

Technical Field

[0001] This utility model relates to the field of phosphogypsum processing technology, specifically to a deep treatment device for phosphogypsum washing liquid. Background Technology

[0002] Phosphogypsum water washing is a processing technique for inert synthetic materials. It is used to remove dirt and residue from the surface of phosphogypsum by using a water washing solution to make the surface smooth and meet the requirements of interior decoration. However, it has been observed that during the water washing process of phosphogypsum, impurities will precipitate in the water washing solution. When too many impurities precipitate, the water washing solution becomes turbid, which will seriously affect the cleaning effect.

[0003] Patent CN220265362U discloses a deep treatment device for phosphogypsum washing liquid. The device comprises a base frame 1, a washing tank 2, a deep treatment tank 3, a drain pipe 4, a filter basket 5, activated carbon granules 6, and purification filter media 7. After simple operation, it can filter and purify the washing liquid used to clean phosphogypsum, effectively removing impurities and preventing excessive sedimentation that could affect the quality and cleaning effect of the washing liquid. A conveying mechanism allows the purified and filtered washing liquid to be returned to the washing tank 2 for recycling. A cleaning placement mechanism further facilitates the process. The system is designed to hold phosphogypsum for washing. The ultrasonic transducer 15 and ultrasonic generator 16 generate ultrasonic waves upon startup, which, combined with the washing solution, allow for ultrasonic washing of the phosphogypsum. This cleaning method is more effective than rinsing. However, the filter basket 5 is prone to clogging during frequent use, increasing the likelihood of backflow. Therefore, staff must frequently disassemble and clean the filter basket 5, a time-consuming and labor-intensive process that increases their workload. Furthermore, if clogging occurs during transport, the equipment must be stopped, potentially interrupting the filtration process. Utility Model Content

The bidirectional threaded rods are rotatably configured with the box opening. The first movable plates at both ends are threadedly engaged with the bidirectional threaded rods. The first and second movable plates are both connected to a cross shaft located in the scissor-type telescopic assembly. The two bidirectional threaded rods are driven by a belt drive assembly. A handle is fixedly disposed at the middle of the outer end of each bidirectional threaded rod. The scissor-type telescopic assembly is used to equidistantly adjust the first and second movable plates. The handle facilitates the rotation of the bidirectional threaded rods by the operator. The belt drive assembly consists of a toothed drive belt and two synchronous pulleys. The two synchronous pulleys are respectively connected to the two bidirectional threaded rods, and the two synchronous pulleys are driven by the toothed drive belt.

[0014] Therefore, this utility model has the following beneficial effects: By utilizing the fluid switching mechanism and the equidistant adjustment interception mechanism, during use, the injected phosphogypsum washing liquid will enter the sealed cover through the inlet, tank, outlet, valve body, and hose. Then, the first and second movable plates will intercept the impurities mixed in the phosphogypsum washing liquid. If blockage occurs due to frequent use, the operator can close the valve body and open the other valve bodies. The operation process is time-saving and labor-saving. Using this method, the continuous filtration work can be guaranteed without stopping the equipment, avoiding interruption. Attached Figure Description
