Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production, and in particular to a construction gypsum roller slag screening device. Background Art

[0002] As paper-faced gypsum board manufacturers, they all use building gypsum as the raw material for production. However, the raw materials will be mixed with some garbage and gravel to a greater or lesser extent. In order to ensure the quality of the building gypsum, the mixed garbage must be removed during the feeding and transportation process of the building gypsum.

[0003] In the prior art, roller slag removers or drum screens are used to remove slag during transportation. However, due to the loose and relatively sticky nature of building gypsum, the roller of the roller screen will be stuck during operation, thus failing to remove debris. Summary of the invention

[0004] The purpose of the present invention is to provide a roller sieve slag removal device for building gypsum, so as to solve the technical problem that the slag removal machine is easy to become sticky and blocked during the material feeding and conveying process of building gypsum in the baking section of the raw material workshop.

[0005] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0006] A construction gypsum roller screen slag removal device, comprising a roller screen and a stainless steel vibrating plate;

[0007] The roller screen is provided with a plurality of rollers arranged in a staggered manner, and the stainless steel vibrating plate is installed below the discharge end of the tail roller of the roller screen and receives the impurities discharged by the roller;

[0008] The rollers are installed in the roller screen through roller shafts, and the lower parts of the roller shafts between adjacent rollers are provided with stainless steel scrapers, and the stainless steel scrapers are used to scrape off the gypsum material attached to the outer wall of the roller shaft.

[0009] Furthermore, the length of each stainless steel scraper is smaller than the spacing width between the two rollers.

[0010] Furthermore, the stainless steel scraper is connected with a lifting spring, and the end of the lifting spring is connected to the inner wall of the roller screen.

[0011] Furthermore, a driving motor is provided at the rear end of the roller screen, and a transmission chain is provided inside the roller screen. The driving motor can drive each roller to rotate through the transmission chain.

[0012] Furthermore, the interior of the stainless steel vibration plate is filled with longitudinal stainless steel round steels, and the stainless steel vibration plate is located lower than the roller screen.

[0013] Furthermore, a micro vibration motor is provided below the stainless steel vibration plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In view of the looseness and relative stickiness of the gypsum material itself, a stainless steel scraper is arranged under each roller. The slag remover can clean up large impurities in the gypsum material at any time and can also self-clean the accumulated material on the roller edge, which is safe, fast and saves labor intensity.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 As shown, the present invention provides a construction gypsum roller sieving and slag removal device, comprising a roller sieving device 6 and a stainless steel vibrating plate 12;

[0023] A plurality of rollers 8 arranged in a staggered manner are installed on the roller screen 6, and a stainless steel vibrating plate 12 is installed below the tail roller discharge end of the roller screen 6 and receives impurities discharged by the roller 8;

[0024] The rollers 8 are installed in the roller screen 6 via roller shafts, and stainless steel scrapers 7 are provided at the lower parts of the roller shafts between adjacent rollers 8, and the stainless steel scrapers 7 are used to scrape off the gypsum material 1 attached to the outer wall of the roller shaft.

[0025] In order to completely clean the gypsum material 1 on the roller surface, the length of each stainless steel scraper 7 is smaller than the spacing width between two rollers 8, and the length of the stainless steel scraper 7 should be only slightly smaller than the spacing width between two adjacent rollers 8.

[0026] In order to ensure that the end of the stainless steel scraper 7 is always in contact with the outer wall of the roller, a lifting spring is connected to the stainless steel scraper 7, and the end of the lifting spring is connected to the inner wall of the roller screen 6.

[0027] In order to feed the gypsum material, a feeding belt bracket 4 can be set up just above the head end of the roller screen 6, and the first conveyor belt 2 can be installed on the feeding belt bracket 4.

[0028] In order to make the gypsum material evenly spread on the surface of the roller 8 of the roller screen 6, a conveyor belt tail wheel 3 is provided at the tail end of the feeding belt bracket 4, and baffles 15 are provided on both sides vertically below the conveyor belt tail wheel 3. The baffles 15 spread the gypsum material 1 evenly to the surface of the roller 8 of the roller screen 6.

[0029] In order to achieve dust prevention effect, a dust cover 5 can also be provided at the tail of the first conveyor belt 2 , and the discharge end of the first conveyor belt 2 is located in the dust cover 5 .

[0030] In order to discharge the gypsum material, a second conveyor belt 11 is set up below the roller screen 6 .

[0031] In the present invention, the rollers 8 can be driven synchronously to achieve continuous screening of the gypsum material 1. To this end, the present invention is designed as follows: a drive motor 9 is provided at the tail end of the roller screen 6, and a transmission chain 10 is provided inside the roller screen 6. The drive motor 9 can drive each roller 8 to rotate through the transmission chain 10.

[0032] In actual application, a small amount of gypsum will also be screened onto the stainless steel vibration plate 12 along with the impurities. To avoid waste, the present invention also makes the following design: the interior of the stainless steel vibration plate 12 is filled with longitudinal stainless steel round steels, and the stainless steel vibration plate 12 is located lower than the roller screen 6.

[0033] A micro vibration motor 13 is provided below the stainless steel vibration plate 12 , and a second conveyor belt 11 is arranged below the roller screen. The second conveyor belt 11 extends to below the stainless steel vibration plate 12 .

[0034] Under the vibration of the stainless steel vibration plate 12, the small-particle gypsum material that can pass through the stainless steel round steel can be sieved onto the second conveyor belt 11 and reused.

[0035] When in use, the gypsum material 1 is transported by the loader to the running first conveyor belt 2, and the driving motor 9 is started to drive the roller 8 to rotate. All the rollers 8 on the roller screen 6 are driven to rotate in the same direction through the transmission chain 10. After the gypsum material 1 is thrown onto the roller screen 6 along the first conveyor belt 2, the baffles 15 on both sides vertically below the tail wheel 3 of the first conveyor belt spread the gypsum material 1 evenly onto the surface of the roller 8.

[0036] As the roller screen 6 operates, the gypsum material with small particles is screened onto the second conveyor belt 11 below and is sent to the next conveying section or enters a temporary storage device.

[0037] At the same time, the stainless steel scraper 7 under each roller 8 promptly scrapes off the building materials attached to the roller surface.

[0038] The large-grained gypsum material 1 or impurities in the raw materials are pushed onto the stainless steel vibrating plate 12 below the tail roller 8 of the roller screen 6 after passing through the roller screen 6. The small-grained raw materials passing through the stainless steel vibrating plate 12 can be screened again and fall into the second transmission belt 11 at the bottom.

[0039] Through the above operations, impurities and small particles of gypsum are basically separated completely, and the problem of clogging of the slag remover during feeding and conveying is solved.

[0040] In summary, in view of the looseness and relative stickiness of the gypsum material itself, a stainless steel scraper 7 is arranged under each roller. The slag remover can clean up large impurities in the gypsum material and also automatically clean up the accumulated material on the roller edge, which is safe, fast and saves manual labor intensity.

[0041] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
