Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cementitious material production, especially to a cementitious material production filtering equipment. BACKGROUND

[0002] After mining, filling is needed, and a very important material in the filling material is cementitious material. In the production and processing process of cementitious material, the raw materials need to be filtered, mainly to filter out some caked raw materials after absorbing moisture, to avoid caking of the produced cementitious material.

[0003] For example, patent application No. CN202321468022.1 discloses a filtering device for cementitious material production. The patent sets up a filter screen 601, a motor 602, a rotating shaft 603, and a rubber threaded conveying piece 604. When the cementitious material slides into the inside of the filter box 2, it will be on the left side of the surface of the filter screen 601. Then, the motor 602 on the left side of the filter box 2 is started to drive the rotating shaft 603 and the rubber threaded conveying piece 604 inside the filter box 2 to rotate. The cementitious material that meets the filtering requirements will be conveyed and dropped to the bottom of the inside of the filter box 2 with the rotation of the rubber threaded conveying piece 604, and then it will be collected by sliding through the discharge opening 5 opened on the front side of the filter box 2. The larger cementitious material that does not meet the filtering requirements will be conveyed to the position of the slag discharge port through the rotation of the rubber threaded conveying piece 604, and then it will be discharged from the inside of the filter box 2. In this way, the filter box 2 can be cleaned in time to avoid blockage, so that the cementitious material can be continuously filtered, and the filtering efficiency is improved.

[0004] The filtering device for cementitious material production in the prior art has some drawbacks after being purchased. Because the filter screen is not tubular, when the threaded conveying piece conveys the caked material, some material cannot be taken away, which causes the accumulation of some material and reduces the filtering effect of the filter screen. UTILITY MODEL CONTENTS

[0005] The technical problem to be solved by the utility model is to provide a cementitious material production filtering equipment to solve the problem of easy blockage of the filtering device for cementitious material production in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a cementitious material production filtering equipment, which comprises

[0007] The filter barrel has a feed hopper on the upper end wall and a discharge pipe on the lower end wall.

[0008] A plurality of filtering structures are arranged in the filter barrel.

[0009] The filtering structure comprises:

[0010] A first filter screen is arranged on the inner wall of the filter barrel and is conical;

[0013] An inner threaded sleeve is detachably arranged on the outer wall of the positioning sleeve and the guide hopper, and the inner threaded sleeve, the positioning sleeve and the guide hopper form a transfer channel, and the transfer channel has a second filter screen;

[0014] The inner wall of the transfer channel has a plurality of discharge ports and feed ports which are in communication with the filter barrel, the discharge ports are located above the edges of the first filter screen, and the feed ports are located below the second filter screen.

[0015] Preferably, the inner wall of the filter barrel has a plurality of hopper-shaped material guiding plates which are located below the feed ports.

[0016] Preferably, the second filter screen is arranged on the inner wall of the filter barrel and is in sliding contact with the inner wall of the inner threaded sleeve.

[0017] Preferably, the positioning sleeve is fixedly connected with an outer threaded sleeve, and the inner threaded sleeve is threadedly connected with the outer threaded sleeve.

[0018] The beneficial effects of the above technical solutions are as follows:

[0019] The first filter screen can filter the raw materials for the first time, and the sieve residue can enter the transfer channel through the discharge ports and be filtered again by the second filter screen. At this time, the sieve residue of the second filter screen can be taken out by removing the outer threaded sleeve, and then the raw materials can enter the filter barrel again through the feed ports.
