when the grain slag filtering device works, small filter residues continuously enter the front spindle head rotating shaft assembly 10 and the rear spindle head rotating shaft assembly 7 under the rotation drive of the main shaft 11, the outermost side of the front spindle head rotating shaft assembly 10 and the outermost side of the rear spindle head rotating shaft assembly 7 are provided with the water retaining ring 33, the water retaining ring 33 is tightly pressed on the gland 34 and matched with the main shaft 11 to be arranged, so that part of water can be effectively blocked, and when a part of a grain slag-water mixture enters the first packing chamber 49 through the water retaining ring 33, the multilayer silica gel seal 32 arranged in the first packing chamber 49 and matched with the main shaft 11 can effectively block the other part of the grain slag-water mixture; when the last part of the slag-water mixture enters the position of the fixed sleeve 35 through the multi-layer silica gel seal 32, the lip of the multi-layer framework oil seal 41 arranged in the fixed sleeve 35 is arranged outwards, so that the slag-water mixture can be prevented from entering the rotor 39 of the bearing 48, the rotor 39 can be damaged, and the service life of the bearing 48 can be shortened; the bearings 48 arranged in the front spindle head rotating shaft assembly 10 and the rear spindle head rotating shaft assembly 7 are protected by the multilayer seals arranged on the left side and the right side, and the framework oil seal 41 and the silica gel seal 32 can bear the high temperature of more than 250 degrees; when the bearings 48 in the front spindle head rotating shaft assembly 10 and the rear spindle head rotating shaft assembly 7 need to be oiled, an operator only needs to add oil from the oil nozzle 46 arranged above the bearing seat cover 47, and the added oil is high-temperature-resistant lithium-based grease; o-shaped rings 36 are arranged between the bearing seat cover 47 and the inner positioning sleeve 44 and the outer positioning sleeve 30 respectively, and O-shaped rings 36 are arranged between the bearing seat 37 and the inner positioning sleeve 44 and the outer positioning sleeve 30 respectively; therefore, the lithium-based grease can be effectively prevented from overflowing, so that the loss of the lithium-based grease is avoided, and the oil consumption is saved; when the maintenance is needed, the front spindle head supporting assembly and the rear spindle head supporting assembly on the two sides of the main frame 15 are provided with the grooves 9 at positions close to the main shaft 11, so that an operator only needs to stretch hands to the grooves 9 and loosen bolts between the spindle heads 43 and the fixed disc 19; the front spindle head supporting assembly and the rear spindle head supporting assembly are integrally replaced, when bolts between the spindle heads 43 and the fixed disc 19 are not loosened, an operator can loosen the bolts on the gland 34 and loosen the bolts on the press plate 29 to easily detach and replace the silica gel seal 32 and the skeleton oil seal 41 on the inner sides of the front spindle head rotating shaft assembly 10 and the rear spindle head rotating shaft assembly 7 conveniently and quickly, and then the front spindle head rotating shaft assembly and the rear spindle head rotating shaft assembly 7 can be maintained and maintained regularly, so that a large amount of time cost is saved, and meanwhile, a space for operating, maintaining and maintaining is provided for the maintenance personnel; the plurality of spray pipes 16 arranged above the main frame 15 are matched with the spray holes 17 for high-pressure washing, so that the slag-water mixture can be more effectively separated and granulated.
The present invention is not limited to the above-mentioned embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some substitutions and modifications to some technical features without creative efforts according to the disclosed technical contents, and these substitutions and modifications are all within the protection scope of the present invention.
