Description

Technical Field

[0001] The utility model belongs to the technical field of epoxy resin waste recycling, in particular to an epoxy resin waste recycling device. Background Art

[0002] After the epoxy resin reacts, it needs to be washed with water until it is neutral. It needs to be washed several times to wash the epoxy resin to neutrality. The raw materials in the reactor cannot react completely. Therefore, the cleaning liquid waste contains some unreacted epichlorohydrin and bisphenol A. It is necessary to use added chemicals to form flocs from the impurities in the liquid waste, and then filter out the flocs and particulate matter for reuse. There are currently two methods for filtering flocs: first, the liquid waste is placed in a tank body, and then chemicals are added. After the flocs are generated, they are manually removed using a filter net. This operation method is time-consuming, labor-intensive, and inefficient, and it is difficult to completely remove the flocs manually, resulting in poor recovery effect; second, a filter net is added at the discharge port of the tank body. The cross-sectional area of ​​the discharge port is small, and the flocs are easy to clog the filter net, and the clogged filter net is difficult to clean. Utility Model Content

[0046] The linear drive assembly is a cylinder 10, the housing of the cylinder 10 is fixedly connected to the filter tank 1, and the output shaft of the cylinder 10 is fixedly connected to the connecting block 9;

[0047] Rotating posts 601 are fixedly provided at both ends of the transverse plate 6 , and a rotating groove matching with the rotating posts 601 is opened on the connecting block 9 . The rotating posts 601 are installed inside the rotating grooves, and the transverse plate 6 is rotatably connected to the connecting block 9 .

[0048] The filter tank 1 is fixed with a guide post 5 arranged along the moving direction of the filter frame 4, and the connecting block 9 is provided with a guide hole corresponding to the guide post 5, and the guide post 5 is installed inside the guide hole. The guide post 5 plays a guiding role in the process of the filter frame 4 moving.

[0049] A linear bearing 901 matching the guide post 5 is arranged in the guide hole, and the guide post 5 is installed on the inner side of the linear bearing 901 .

[0050] The lower end of the filter tank 1 is an inverted cone structure, and the discharge pipe 102 is located at the bottom end of the inverted cone structure. The inverted cone structure facilitates the outflow of materials.

The filter plate 202 not only plays the role of filtering large-sized aged epoxy resin particles, but also enables the liquid in the buffer chamber to flow evenly and slowly into the sedimentation chamber 206. The pulsed feeding of the liquid inlet pipe 203 disturbs the sediment at the bottom of the sedimentation chamber 206. The sedimentation chamber 206 After a period of sedimentation, the valve on the liquid outlet pipe 204 is opened, and the liquid waste flows into the filter tank 1 through a pump or under the effect of height difference, and then medicine is added to the filter tank 1 to form flocs with impurities therein. At the same time, the motor 8 is started and the stirring paddle 701 is stirred to make the mixing more uniform. Then the filter frame 4 moves upward, and the filter net 3 filters out the flocs. In some embodiments, the filtered liquid is directly used as raw water to achieve full utilization. In other embodiments, the filtered liquid is evaporated by an evaporator and condensed by a condenser to collect raw materials with higher purity.

[0061] Compared with the traditional manual filtration of flocs, the filtration process of the recovery device of the present application is convenient and the filtration efficiency is improved. Compared with installing a filter at the discharge port, the filter structure of the recovery device of the present application is large in area and not easy to be clogged.

[0062] When the filter 3 needs to be cleaned, the filter frame 4 is moved upward, and then the filter frame 4 is rotated so that the filter frame 4 and the opening of the filter 3 face downward. The filter 3 is cleaned manually using a scraper or a high-pressure water tank. The operation process is convenient and the working efficiency of the filter 3 is improved.
