Technical Field

[0001] The present invention relates to the technical field of chlorinated polyethylene filtration, and particularly to an anti-caking filtration device for liquid chlorinated polyethylene. Background Art

[0002] Chlorinated polyethylene, with the chemical name CPE, is a saturated polymer material, having excellent stability, weather resistance, ozone resistance, chemical resistance and aging resistance, and is widely used in the fields of plastics, rubber, building materials, electromechanics, automobiles, military industries, etc. The aqueous suspension process for producing chlorinated polyethylene mainly includes several steps such as chlorination, deacidification, centrifugal separation, drying and mixing packaging. During production, the intermediate materials of chlorinated polyethylene are prone to caking in each technological process. The caking of materials will cause product losses, reduce production, increase production costs, and more seriously, it will have a very serious impact on the normal production of the next process, causing blockages in pipeline equipment, etc., making the subsequent production difficult to carry out.

[0003] The existing devices have a single way of filtering chlorinated polyethylene. When filtering raw materials, they cannot avoid the problem of raw material loss of chlorinated polyethylene caused by excessive caking, and cannot squeeze and filter the caked raw materials, resulting in waste of a large amount of liquid raw materials.

[0007] Preferably, the stirring device further includes a rotating disk, the top of the rotating disk is fixedly connected to the stirring cylinder, a feeding frame is communicated with the top of the stirring cylinder, an arc-shaped opening is formed in the outer side of the stirring cylinder, a filtering device is installed inside the arc-shaped opening, the chlorinated polyethylene continuously moves towards the elastic filter screen under the action of centrifugal force, and the elastic filter screen filters out the lumps in the raw materials that cannot be crushed and retains them on one side of the elastic filter screen, which can filter the chlorinated polyethylene. While filtering the raw materials by centrifugal force, the static mixing blades stir the raw materials, which can prevent excessive agglomeration of the raw materials from affecting the filtering efficiency and effectively improve the filtering rate. A connecting sleeve is sleeved on the outer side of the stirring rod. Pour the liquid chlorinated polyethylene into the stirring cylinder from the feeding frame, and start the driving motor. The driving motor drives the stirring cylinder to rotate through the rotating disk. The chlorinated polyethylene in the stirring cylinder is thrown to the filtering device under the action of centrifugal force, flows into the treatment cylinder after being filtered by the filtering device. When the stirring cylinder rotates, the stirring rod is stationary relative to the stirring cylinder. When the chlorinated polyethylene is thrown towards the filtering device under the action of centrifugal force, it contacts the mixing blades, and the static mixing blades stir and agitate the rotating chlorinated polyethylene, crushing the agglomerated chlorinated polyethylene and effectively avoiding the loss of chlorinated polyethylene raw materials caused by excessive agglomeration.

The chlorinated polyethylene in the stirring cylinder is thrown to the elastic filter screen under the action of centrifugal force. Start the electric telescopic rod and pull the elastic filter screen into the stirring cylinder through the discharging device. The elastic filter screen continuously contracts its internal space. As the internal space of the elastic filter screen decreases after deformation, the elastic filter screen squeezes the raw materials accumulated on one side of the elastic filter screen, which can squeeze and filter the raw materials accumulated on one side of the elastic filter screen, squeeze the agglomerated raw materials to squeeze out the liquid inside, and reduce the waste of liquid raw materials.

[0030] During use, the liquid chlorinated polyethylene is poured into the mixing cylinder 71 from the feeding frame 75, and the driving motor 2 is started. The driving motor 2 drives the mixing cylinder 71 to rotate through the rotating disk 74. The chlorinated polyethylene in the mixing cylinder 71 is thrown to the filtering device 77 under the action of centrifugal force, and flows into the processing cylinder 1 through the filtering of the filtering device 77.

The elastic filter screen 773 continuously contracts its internal space. As the internal space of the elastic filter screen 773 decreases after deformation, the elastic filter screen 773 squeezes the raw materials accumulated on one side of the elastic filter screen 773, which can squeeze and filter the raw materials accumulated on one side of the elastic filter screen 773, squeeze the agglomerated raw materials to squeeze out the liquid inside, and reduce the waste of liquid raw materials.
