Description

Technical Field

[0001] This utility model relates to the field of refractory brick production technology, and in particular to a refractory brick material grinding device. Background Technology

[0002] In the production of refractory bricks, various raw materials need to be ground first, then extruded into refractory brick shapes using a brick press, and finally baked at high temperatures to set the shape. Currently, ball mills are mostly used to grind refractory brick materials. However, existing ball mills are inconvenient to use for feeding materials. After grinding, a person needs to manually remove the material with a tool, and the material will mix with the grinding balls inside the mill, requiring manual sorting, which is quite troublesome. Therefore, in view of the above situation, there is an urgent need to develop a refractory brick material grinding device that automatically tilts the feed and can automatically separate the material from the grinding steel balls, making it more convenient to use and saving manpower, in order to overcome the shortcomings of current practical applications and meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide a grinding device for refractory brick materials to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A refractory brick grinding device includes a grinding cylinder, a support, a screening and feeding mechanism, a rotary drive mechanism, a base, and a lifting mechanism. The grinding cylinder is rotatably mounted on the support, and multiple grinding steel balls are movably arranged inside the grinding cylinder. A support shaft is fixed to the lower end of the support, and the support shaft is rotatably connected to the base. Two lifting mechanisms are installed at the rear end of the base, and the lifting mechanisms are connected to the rear end of the support and used to lift the support. The rotary drive mechanism is fixedly mounted on the support and used to drive the grinding cylinder to rotate. The screening and feeding mechanism includes: a baffle plate, a screening screen, a rotary adjustment shaft, and a support. The support block and the tightening bolt are attached to the front end of the grinding cylinder. The baffle plate and the screening screen are fixed to the rotary adjustment shaft. The support block is fixed on the grinding cylinder. The rotary adjustment shaft is rotatably connected to the support block. The support block is equipped with a tightening bolt that is turned to clamp the rotary adjustment shaft. The mesh diameter of the screening screen is smaller than the diameter of the grinding steel ball. The lifting mechanism includes a hydraulic cylinder, a first rotating shaft and a second rotating shaft. The bottom of the hydraulic cylinder is rotatably connected to the base through the first rotating shaft. The piston rod of the hydraulic cylinder is rotatably connected to the bottom of the support through the second rotating shaft.

[0006] Preferably, a polyurethane wear-resistant layer is fixed inside the grinding cylinder.

[0007] Preferably, the rotary drive mechanism includes a motor, a pinion, and a gear. The motor is fixed on a bracket, and a pinion is fixed on the output shaft of the motor. A gear meshing with the pinion is provided on one side of the pinion, and the gear is fixed to the outside of the grinding cylinder.

[0008] Preferably, a miniature hydraulic station is fixedly installed on the base, and the hydraulic cylinder is connected to the miniature hydraulic station through a pipeline.

[0009] The beneficial effects of this utility model are as follows: During grinding, the grinding cylinder and support are first placed horizontally. Refractory brick material is added to the grinding cylinder, and then the baffle plate is rotated to the front end of the grinding cylinder to block its inlet and outlet, preventing material from falling out during grinding. The tightening bolts are then tightened to clamp the rotating adjusting shaft, preventing it from rotating. Next, the rotating drive mechanism is activated to rotate the grinding cylinder. The rotation of the grinding cylinder causes the grinding steel balls inside to roll, squeezing and rubbing the refractory brick material, thus grinding it. After grinding, a collection box is placed below the front end of the grinding cylinder. Then, the tightening bolts are loosened, and the screening screen is rotated to the front of the grinding cylinder's inlet and outlet. The tightening bolts are then tightened again. Then, the piston rod of the hydraulic cylinder extends to lift the rear end of the support. The support rotates around the support shaft, causing the support and grinding cylinder to form an inclined state with the rear end higher than the front end, allowing the material inside the grinding cylinder to slide down towards the screening screen for discharge. At this time, the rotating drive mechanism drives the grinding cylinder to rotate slowly to improve the discharge efficiency. In summary, this utility model features automatic tilting feeding and can automatically separate materials from grinding steel balls, making it more convenient to use and saving manpower.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] See Figures 1-6 In this embodiment of the utility model, a refractory brick material grinding device includes a grinding cylinder 1, a support 2, a screening and feeding mechanism 3, a rotary drive mechanism 4, a base 5, and a lifting mechanism 6. The grinding cylinder 1 is rotatably mounted on the support 2. A polyurethane wear-resistant layer 101 is fixed inside the grinding cylinder 1 to increase the wear resistance of the inner wall of the grinding cylinder 1. Multiple grinding steel balls 102 are movably arranged inside the grinding cylinder 1 for grinding refractory brick raw materials. A support shaft 201 is fixed at the lower end of the support 2 and is rotatably connected to the base 5. The base 5 is fixed to the ground. Two lifting mechanisms 6 are installed at the rear end of the base 5. The lifting mechanisms 6 are connected to the rear end of the support 2 and are used to lift the support 2. The rotary drive mechanism 4 is fixedly mounted on the support 2 and is used for grinding refractory brick raw materials. The grinding cylinder 1 is driven to rotate. The screening and feeding mechanism 3 includes: a baffle plate 301, a screening screen 302, a rotating adjustment shaft 303, a support block 304, and a tightening bolt 305. The baffle plate 301 and the screening screen 302 are both attached to the front end of the grinding cylinder 1. The baffle plate 301 and the screening screen 302 are both fixed to the rotating adjustment shaft 303. The support block 304 is fixed on the grinding cylinder 1. The rotating adjustment shaft 303 is rotatably connected to the support block 304. The support block 304 is equipped with a tightening bolt 305, which is tightened to clamp the rotating adjustment shaft 303. When the tightening bolt 305 clamps the rotating adjustment shaft 303, the rotating adjustment shaft 303 cannot rotate. The mesh diameter of the screening screen 302 is smaller than the diameter of the grinding steel ball 102, so that the grinding steel ball 102 cannot pass through the screening screen 302 and be discharged.

[0021] The rotary drive mechanism 4 includes a motor 401, a pinion 402, and a gear 403. The motor 401 is fixed on the bracket 2. The pinion 402 is fixed on the output shaft of the motor 401. A gear 403 meshes with the pinion 402 on one side. The gear 403 is fixed on the outside of the grinding cylinder 1. In use, the motor 401 drives the pinion 402 and the gear 403 to rotate, and the gear 403 drives the grinding cylinder 1 to rotate.

[0022] The lifting mechanism 6 includes a hydraulic cylinder 601, a first rotating shaft 602, and a second rotating shaft 603. The bottom of the hydraulic cylinder 601 is rotatably connected to the base 5 via the first rotating shaft 602, and the piston rod of the hydraulic cylinder 601 is rotatably connected to the bottom of the support 2 via the second rotating shaft 603. In use, the piston rod of the hydraulic cylinder 601 extends to lift the rear end of the support 2. The support 2 rotates around the support shaft 201, so that the support 2 and the grinding cylinder 1 form an inclined state with the rear end higher than the front end, so that the material in the grinding cylinder 1 can be discharged.

[0023] A miniature hydraulic station 7 is fixedly installed on the base 5. The hydraulic cylinder 601 is connected to the miniature hydraulic station 7 through a pipeline, and the miniature hydraulic station 7 supplies hydraulic oil to the hydraulic cylinder 601.

[0024] A PLC controller 8 is installed on the base 5, and the PLC controller 8 is used to control the operation of the motor 401 and the hydraulic cylinder 601.

[0025] Working principle: In this refractory brick grinding device, the grinding cylinder 1 and support 2 are first placed horizontally. Refractory brick material is added to the grinding cylinder 1. Then, the baffle plate 301 is rotated to the front end of the grinding cylinder 1 to block its inlet and outlet, preventing material from falling out during grinding. The tightening bolt 305 is then tightened to clamp the rotating adjusting shaft 303, preventing it from rotating. Next, the rotating drive mechanism 4 is started to rotate the grinding cylinder 1. The rotation of the grinding cylinder 1 causes the grinding steel balls 102 inside to roll, and the grinding steel balls 102 squeeze and rub the refractory brick material, thereby grinding the refractory brick material. After the material is ground, a collection box is placed below the front end of the grinding cylinder 1. Then, the top bolt 305 is loosened, and the screening screen 302 is rotated to the front of the inlet and outlet of the grinding cylinder 1. The top bolt 305 is then tightened. Then, the piston rod of the hydraulic cylinder 601 extends to lift the rear end of the support 2. The support 2 rotates around the support shaft 201, so that the support 2 and the grinding cylinder 1 form an inclined state with the rear end higher than the front end, so that the material in the grinding cylinder 1 slides down to the screening screen 302 for discharge. At this time, the rotary drive mechanism 4 drives the grinding cylinder 1 to rotate slowly to improve the discharge efficiency.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
