Description

Technical Field

[0001] The utility model relates to the technical field of gypsum board preparation, in particular to a plough-type stirring scraper. Background Art

[0002] Gypsum board is made of gypsum, water, various additives and foaming agents mixed to form slurry, which is then poured on cardboard and undergoes a series of processes to form the finished gypsum board. In the production process of gypsum board, coagulant is an indispensable additive, which plays a role in accelerating the coagulation of gypsum. The quality of coagulant addition directly affects the stability of the production line. At present, the coagulant is added to the mixing reamer through the discharge port of the storage bin, and then the various auxiliary materials are transported from the mixing reamer to the mixer.

[0003] However, due to the poor fluidity of the coagulant, it is easy to form lumps. The coagulant often adheres to the wall of the storage bin or the discharge port, causing the bin or the discharge port to be blocked and the material cannot be discharged. Therefore, a disc-type scraper is further installed in the bin or at the discharge port to scrape off the material blocks attached to the bin wall to facilitate the discharge of the material.

[0004] However, in some storage silos, the silo wall is inclined, and an angle will be formed between the inclined silo wall and the cavity wall of the vertically set discharge port. When the coagulant passes through this angle, a large amount of it will be attached, causing siltation and thus causing blockage. The current disc-type scraper cannot scrape the material at this angle, and the operator often needs to knock on the outer wall to ensure normal discharge. Summary of the invention

[0005] The utility model aims to provide a plough-type stirring scraper to solve the technical problem in the prior art that a disc-type scraper cannot be used due to the angle formed between the bin wall and the material discharge port.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] A plow-type stirring scraper comprises a main shaft, on which a plurality of connecting columns are arranged, the plurality of connecting columns are distributed in a circular array around the outer surface of the main shaft, and there are spacings between adjacent connecting columns;

[0008] One end of the connecting column is installed on the main shaft, and the other end is connected with a V-shaped cutter head, and one end of the V-shaped cutter head that is closed together is arranged on the connecting column.

[0009] As a preferred solution of the utility model, the outer inclined surface of the V-shaped cutter head includes a fitting section and an idle section, the fitting section is fitted with the inclined wall of the storage bin, and the idle section is recessed toward the center of the V-shaped cutter head to form a groove, and the groove is arranged opposite to the angle formed by the inclined wall of the storage bin and the wall of the discharge mouth.

[0010] As a preferred embodiment of the present utility model, a flexible member is provided on the fitting section of the outer inclined surface of the V-shaped cutter head.

[0011] As a preferred embodiment of the present utility model, the flexible member is a flexible felt or a flexible brush.

[0012] As a preferred embodiment of the present utility model, the outer surfaces of the V-shaped cutter head, the connecting column, and the main shaft are all provided as smooth surfaces.

[0013] The present utility model has the following beneficial effects compared with the prior art:

[0014] By providing a V-shaped cutter head and making the V-shaped cutter head fit the inclined surface of the storage bin, when the main shaft drives the V-shaped cutter head to rotate, the coagulant at the bending part and near the bending part is removed by direct scraping and frictional vibration. In addition, a groove is provided on the outer inclined surface of the V-shaped cutter head. Therefore, special design of the feeding port or the bin wall of the storage bin is not required, and interference between the V-shaped cutter head and the bin wall can be avoided.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Such asFigure 1 As shown in the figure, the utility model provides a plough-type stirring scraper, which includes a main shaft 1. The main shaft 1 passes through the feeding port of the storage bin and is arranged below the inclined bin wall of the storage bin. A plurality of connecting columns 2 are evenly distributed on the main shaft 1. One end of the connecting column 2 is installed on the main shaft 1, and the other end is connected with a V-shaped cutter head 3. The converging end of the V-shaped cutter head 3 is arranged on the connecting column 2.

[0022] Among them, the outer inclined surface of the V-shaped cutter head 3 on the main shaft 1 close to the inclined bin wall of the storage bin is arranged in contact with the inclined bin wall of the storage bin.

[0023] In this device, when the main shaft 1 rotates, it drives the V-shaped cutter head 3 to rotate by friction on the inclined bin wall of the storage bin. Thus, when the coagulant falls, it will not adhere to this position, or the coagulant that has already adhered to this position will be scraped off. At the same time, the friction between the V-shaped cutter head 3 and the bin wall, which drives the bin wall to vibrate, will further prevent the adhesion of the coagulant.

[0024] Furthermore, the outer inclined surface of the V-shaped cutter head 3 includes a fitting section 4 and a vacant section 5. The fitting section 4 is arranged in contact with the inclined bin wall of the storage bin. The vacant section 5 is recessed towards the center of the V-shaped cutter head 3 to form a groove 6. The groove 6 is arranged facing the fold angle formed by the bin wall of the storage bin and the wall of the feeding port cavity.

[0025] The rotation in contact with the inclined bin wall of the storage bin may scrape against the wall of the vertical feeding port below it. Therefore, a groove 6 is provided on the outer inclined surface of the V-shaped cutter head 3, and the groove 6 is arranged facing the bending place (the bending is formed by the connection of the inclined bin wall of the storage bin and the vertical wall of the feeding port. The existence of the groove 6 is to avoid the interference of the V-shaped cutter head 3 with the wall of the feeding port when it rotates). Thus, when the V-shaped cutter head 3 rotates, it can avoid the wall of the bending place to prevent it from scraping against the wall.

[0026] In addition, a flexible part 7 is arranged on the surface of the V-shaped cutter head 3 in contact with the inclined bin wall of the storage bin. The V-shaped cutter head 3 is in contact with the inclined bin wall of the storage bin through the flexible part 7.

[0027] If the V-shaped cutter head 3 is made of a hard material, then its hard contact and friction with the bin wall may cause wear. In the long run, if it cannot be fitted, it may lead to poor material removal effect. Therefore, the V-shaped cutter head 3 is in flexible contact with the bin wall through the flexible part 7. And the flexible part 7 can be a flexible felt or a flexible brush, and is detachably and movably connected to one side of the V-shaped cutter head 3. Thus, even if wear occurs, it can be replaced more conveniently.

[0028] In addition, the connecting column 2 and the V-shaped cutter head 3 form a plough-type scraper. A plurality of plough-type scrapers are arranged in a circular pattern on the outer surface of the main shaft 1, and there is a spacing between adjacent plough-type scrapers. Specifically, adjacent plough-type scrapers can be installed on the main shaft with a design of an angular difference of 120° and a spacing difference of 50 mm.

[0029] In this device, a plurality of plow-shaped scrapers are arranged on the main shaft. The two plow-shaped scrapers at the two side positions use the outer inclined surfaces of the V-shaped cutter heads 3 to fit against the bin wall for rotary scraping, while the plow-shaped scraper in the middle uses its continuous rotation at the feeding port position to agitate the feeding, so that this device can not only prevent the bin from being blocked due to the adhesion of the coagulant on the bin wall, but also promote the rapid feeding at the feeding port and avoid the blockage of the coagulant at the center position of the feeding port. Therefore, the V-shaped cutter heads 3 in this device can adopt a design with a relatively thin thickness and a relatively long length. The relatively long length can make the area of contact with the bin wall larger, so that a larger area of the bin wall can be scraped, and the relatively thin thickness can prevent it from receiving too much resistance when rotating.

[0030] Furthermore, the outer surfaces of the V-shaped cutter heads 3, the connecting columns 2 and the main shaft 1 are all set to be smooth surfaces. The design of the smooth surfaces can make the coagulant stay on them as little as possible when the coagulant is fed. Specifically, a stainless steel smooth surface can be adopted.

[0031] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
