[0002] At present, particle bed filtration mechanisms are mostly used in filtration during the processing of petrochemical products, playing an important role in the processing of petrochemical products.

[0003] During use, the existing granular bed filter mechanism can use multiple groups of particle layers to perform multi-stage filtration on the product. However, since the multiple groups of particle layers are not convenient for independent replacement as a whole, the use effect of the filter mechanism is not good. Therefore, in order to advance the technology of the industry, better realize the function of particle replacement in the filter mechanism, and improve the competitiveness of core technology, the present application proposes a new implementation scheme that is different from the internal structure of the granular bed filter mechanism in the prior art.

[0007] Furthermore, both sides of the main hollow drawer are provided with snap-fits.

[0008] Furthermore, both side outer walls of the bed shell are rotatably connected with threaded rods, the threaded rods are clamped with the bayonet, and a butterfly nut is threadedly sleeved at one end of the threaded rods.

[0009] Furthermore, one side of the main hollow drawer and one side of the auxiliary hollow drawer are both provided with side openings.

[0010] Furthermore, a guide frame is fixedly connected to the top of the bed shell.

[0011] Furthermore, a sealing gasket is bonded to the bottom of the guide frame.

[0012] Furthermore, transparent plates are embedded on both sides of the bed shell.

[0013] The beneficial effects of the utility model are:

[0014] 1. Pull the main hollow drawer outward to pull it out of the bed shell, then pull the filter sub-assembly outward to pull it out of the main hollow drawer, so as to facilitate the replacement of the filter particle layer and improve the use effect of the filter mechanism.

[0015] 2. Fix the main hollow drawer by engaging the threaded rod with the bayonet and then tightening the butterfly nut to prevent the main hollow drawer from falling out of the bed shell.

[0016] 3. Use a sealing gasket to seal the guide frame and the main hollow drawer to prevent the product from falling into the gap between the main hollow drawer and the bed shell. BRIEF DESCRIPTION OF THE DRAWINGS
