Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, a papermaking pulp degritting machine, includes main part 1, the inside of main part 1 is provided with delivery pipe 2, the inner wall of main part 1 is provided with spiral line 3, one side of main part 1 is provided with feed inlet 4, the top of main part 1 is provided with filters storehouse 5, the inside of filtering storehouse 5 is provided with standing groove 6, the inside of standing groove 6 is provided with filter 7, the inside of filter 7 is provided with filter screen 8, the top of filtering storehouse 5 is provided with connector 10, the bottom of main part 1 is provided with whirl degritting section of thick bamboo 11, the bottom of whirl degritting section of thick bamboo 11 is provided with collection storehouse 12, one side of collecting storehouse 12 is provided with wash water mouth 13, the bottom of collecting storehouse 12 is provided with valve 14.

In this embodiment: through the spiral veins 3, the rotational flow sand removing cylinder 11 and the filter plate 7, paper pulp enters the main body 1 from the feeding port 4 and flows into the rotational flow sand removing cylinder 11 in a thread shape under the action of the spiral veins 3 on the inner wall of the main body 1, after the paper pulp enters the rotational flow sand removing cylinder 11, the paper pulp moves downwards along the rotation of the cylinder body because the rotational flow sand removing cylinder 11 is in a conical structure, when water flow reaches a certain part of a cone, the paper pulp rotates upwards along the axis of the cylinder body and finally enters the discharge pipe 2 of the main body 1, gravel in the paper pulp falls into the collection bin 12 below the cylinder wall under the action of inertial centrifugal force and self gravity to complete primary filtration, when the paper pulp entering the discharge pipe 2 contacts the filter plate 7 in the filter bin 5, the gravel which is not separated out in the paper pulp is adsorbed in the filter screen 8 in the filter plate 7, thereby further filtering the paper pulp, and combining the two, make the grit in the paper pulp can very big degree be clear away totally, improve the quality of later stage output paper greatly, and simultaneously, filter 7 in the filter house 5, the staff is direct to be taken out in by standing groove 6 and is changed, convenient and fast, valve 14 through setting up, wash port 13, after the use, can directly open the valve 14 of collecting the 12 bottoms in storehouse, discharge the grit of isolating, as for the adhesion at the grit of collecting 12 inner walls in storehouse, can be by the water pipe that wash port 13 is connected, wash collecting 12 insides in storehouse, the completion is to the cleanness of collecting 12 storehouse.

Please refer to fig. 1 and fig. 2, a through hole with the same caliber as the exhaust pipe 2 is arranged inside the filtering bin 5, the size of the filtering plate 7 is matched with the placing groove 6, the filtering plate 7 is made of rubber, the main body 1 is a hollow cylinder structure, the main body 1 is detachably connected with the rotational flow sand removing cylinder 11 through a nut, and when the paper pulp entering the exhaust pipe 2 contacts the filtering plate 7 in the filtering bin 5, gravel which is not separated out in the paper pulp is adsorbed in the filter screen 8 in the filtering plate 7 through the arranged filtering plate 7, thereby further filtering the paper pulp.

Please refer to fig. 1 and fig. 2, the cyclone sand removing cylinder 11 is a conical structure, the brackets 15 are arranged outside the cyclone sand removing cylinder 11, the number of the brackets 15 is three, the three brackets 15 are positioned outside the cyclone sand removing cylinder 11 and distributed in a triangular manner, and the cyclone sand removing cylinder 11 is a conical structure, so that the pulp is pushed downwards along the rotation of the cylinder, when the water flow reaches a certain position of the cone, the pulp rotates upwards along the axis of the cylinder, and finally enters the discharge pipe 2 of the main body 1, and the gravel in the pulp falls into the collection bin 12 below along the cylinder wall under the action of inertial centrifugal force and self gravity.

Please refer to fig. 1 and fig. 2, the connecting port 10, the feeding port 4 and the flushing port 13 are provided with flanges at their ends, and a handle 9 is provided at one side of the filtering plate 7, so that the operator can directly draw out the filtering plate from the placing groove 6 for replacement through the handle 9, which is convenient and fast.

The working principle is as follows: before use, a connecting port 10, a feeding port 4 and a flushing port 13 on the device are respectively connected with pipelines corresponding to the outside, the pipelines connected with the feeding port 4 need to be pressurized by a pressure pump, meanwhile, a filter plate 7 is placed in a filter bin 5, when the device is used, paper pulp enters a main body 1 from the feeding port 4 and flows into a rotational flow desanding cylinder 11 in a threaded manner under the action of spiral grains 3 on the inner wall of the main body 1, after the paper pulp enters the rotational flow desanding cylinder 11, the paper pulp rotates and pushes downwards along the wall of the rotational flow desanding cylinder 11 due to the conical structure of the rotational flow desanding cylinder 11, after reaching a certain part of the rotational flow desanding cylinder 11, the paper pulp rotates upwards along the axis of the cylinder and finally enters a discharge pipe 2 of the main body 1, gravel in the paper pulp falls into a collection bin 12 below the cylinder wall under the action of inertial centrifugal force and self gravity to complete primary filtration, and when the paper pulp entering the discharge pipe 2 contacts with the filter plate 7 in the filter bin, the grit that is not in the paper pulp will be adsorbed in filter screen 8 in filter 7, thereby further filter paper pulp, the two combines, make the grit in the paper pulp can very big degree be clear away totally, improve the quality of later stage output paper greatly, and simultaneously, filter 7 in the filter house 5, the staff is direct to be taken out in standing groove 6 and is changed, convenient and fast uses the back, can be directly open the valve 14 who collects storehouse 12 bottoms, discharge the grit of separation, usable wash port 13 simultaneously, it is inside clean to collect storehouse 12.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
