Description

Technical Field

[0001] The utility model relates to the technical field of polishing powder waste recovery, in particular to a rare earth polishing powder waste recovery and sedimentation device. Background Art

[0002] Rare earth polishing powder is widely used in industrial production for polishing of glass, ceramics, metals and other materials. However, the waste generated in the production process contains a large amount of rare earth elements and other valuable components. Currently, waste recovery and sedimentation equipment is used to treat it. Among them, the "multi-stage sedimentation recovery device for rare earth polishing powder waste" disclosed by the authorization number "CN205235487U" has solved the problem that the rare earth polishing powder waste slurry has a certain viscosity, which is very easy to clog pipes and sewage wells when discharged directly, and is difficult to clean, causing pollution to water and the environment. After further searching, it was found that the "multi-stage sedimentation recovery device for rare earth polishing powder waste" disclosed by the authorization number "CN219128585U" has solved the problem of pollution to water and the environment through specific technical means. The structural setting effectively solves the technical disadvantages of multi-stage sedimentation through vertical baffles, and the wastewater can only flow after sedimentation is completed, but the efficiency of this sedimentation is very slow. However, in actual use, a rare earth polishing powder waste recovery and sedimentation device with a similar structure still has many defects, such as: most of the existing sedimentation methods use chemical sedimentation or physical sedimentation to treat polishing powder waste, but gas discharge is easy to cause air pollution during the sedimentation process, there is a lack of sedimentation sealing structure, and the waste after sedimentation is mixed with liquid, which is not conducive to recycling, and the exhaust gas generated during the sedimentation process lacks a treatment mechanism, so it is necessary to design a rare earth polishing powder waste recovery and sedimentation device. Utility Model Content

[0003] The utility model aims to provide a rare earth polishing powder waste recovery and sedimentation device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rare earth polishing powder waste recovery and sedimentation device, comprising a sedimentation tank, a guide plate and an exhaust gas purification tank, the guide plate is fixedly connected to the bottom of the sedimentation tank, a discharge pipe is fixedly installed on one side of the sedimentation tank, a waste collection device is movably installed on one side of the sedimentation tank, a filter screen is fixedly installed inside the waste collection device, an exhaust gas purification tank is movably installed on the other side of the sedimentation tank, an exhaust pipe is fixedly installed between the sedimentation tank and the exhaust gas purification tank, a partition is fixedly installed inside the exhaust gas purification tank, an exhaust port is opened on the other side of the partition, and an activated carbon adsorption net is fixedly installed on the top of the partition inside the exhaust gas purification tank.

[0005] First, the staff adds the polishing powder waste into the sedimentation tank to react with chemical reagents, and the sedimentation tank is sealed to prevent leakage of gas generated by the reaction. Then the guide plate guides the settled polishing waste and liquid through the discharge pipe and discharges into the waste collection equipment. The settled solids are then filtered through the filter and blocked at the top of the filter, so that the liquid and the fixed are separated and collected, which is convenient for the staff to recycle the polishing sediment. Then the waste gas generated by the sedimentation is discharged into the bottom of the waste gas purification tank through the exhaust pipe, and then the gas contacts the waste gas purifier, which is hydrogen peroxide and ferrous sulfate. After the waste gas is purified, it is discharged upward through the exhaust port. After passing through the activated carbon adsorption net, the impurities in the gas are adsorbed and then discharged, avoiding the impact of the gas generated during the sedimentation process on the environment.

The control panel is used to conveniently control the switch of the device, and by opening the valve, the sediment and liquid after sedimentation can be discharged into the interior of the waste collection device through the discharge pipe.

[0008] Preferably, a first feed inlet is fixedly installed through the rear end of the top of the sedimentation tank, and an outlet pipe is fixedly connected through the other side of the top of the waste gas purification tank.

[0010] Preferably, a second feed port is provided on the other side of the bottom of the exhaust gas purification tank, and a sealing plug is installed inside the second feed port. The gas purifier is conveniently added into the exhaust gas purification tank through the second feed port, and then sealed by the sealing plug, which is convenient for the operation of the staff.

[0011] Preferably, a sealing cover is rotatably mounted on the top of the waste collection device, and a handle is fixedly mounted on the other side of the top of the sealing cover. The staff holds the handle and opens the sealing cover to facilitate the collection and processing of the waste settled on the top of the filter screen.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting up a guide plate, waste collection equipment and a filter screen, the staff first adds the polishing powder waste into the sedimentation tank to react with the chemical reagent, and the sedimentation tank is in a sealed state to avoid the leakage of gas generated by sedimentation and the leakage of gas generated by the reaction. Then the guide plate guides the settled polishing waste and liquid through the discharge pipe to the interior of the waste collection equipment, and then the settled solids are blocked at the top of the filter screen after filtering through the filter screen, so that the liquid is separated and collected, which is convenient for the staff to recycle the polishing sediment.

[0014] 2. By setting up an exhaust pipe, a partition and an activated carbon adsorption net, the waste gas generated by sedimentation is discharged into the bottom of the waste gas purification tank through the exhaust pipe, and then the gas contacts the waste gas purifier, which is hydrogen peroxide and ferrous sulfate. After the waste gas is purified, it is discharged upward through the exhaust port. After passing through the activated carbon adsorption net, the impurities in the gas are adsorbed and then discharged, thus avoiding the impact of the gas generated during the sedimentation process on the environment.
