Description

Technical Field

[0001] The invention relates to the technical field of refractory material production, in particular to a raw material grinding device for refractory material production. Background Art

[0002] Unshaped refractory materials are refractory materials made of refractory aggregates with a certain particle size distribution and powders, binders, and admixtures. They are also called loose refractory materials and are used for the lining of thermal equipment. They are directly baked and used without going through the firing process. The main raw materials of refractory materials are: refractory clay, siliceous raw materials, dolomite, magnesite, graphite, pyrophyllite, vermiculite, peridotite, serpentine, chromite, high-aluminum minerals, zircon, etc. In the production process of unshaped refractory materials, different materials need to be ground for uniform subsequent mixing.

[0003] The prior art discloses a raw material pretreatment device for preparing multi-layer composite refractory materials with publication number CN117101839B. The raw material pretreatment device for preparing multi-layer composite refractory materials crushes and pulverizes the materials through crushing rollers and crushing blades, and then drives multiple grinding plates to slide back and forth inside the grinding groove through a servo hydraulic cylinder. The materials fall under the action of gravity to avoid inadequate grinding. The ground powder materials fall down into the screen bucket and follow the grinding plates to sieve back and forth to avoid mutual adhesion, while screening materials that do not meet the particle size requirements.

[0004] However, there are still some problems in actual use. Since the feed port of the device lacks a shielding structure, a large amount of powder will be generated and diffused from the feed port during the grinding of refractory raw materials.

DETAILED DESCRIPTION

[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figure 1-7 The raw material grinding equipment for refractory material production shown in the figure comprises a grinding box 1, a grinding mechanism is arranged inside the grinding box 1, a fixed block 2 is fixedly connected to the top of the grinding box 1, a circular groove 3 is provided at the bottom of the fixed block 2, an upper opening 4 is provided through the top of the fixed block 2, a lower opening 5 is provided at the top of the grinding box 1 and at a position corresponding to the upper opening 4, an upper disc 6 and a lower disc 7 are rotatably connected to the upper and lower ends of the inner side of the circular groove 3 respectively, a rectangular frame 8 is fixedly connected to the inner side of the circular groove 3 and located between the upper disc 6 and the lower disc 7, a top hole 9 is provided at the eccentric position of the top of the upper disc 6, and a bottom hole is provided at the eccentric position of the top of the lower disc 7 34, and the top hole 9 and the bottom hole 34 are symmetrically arranged, a driving motor 11 is fixedly connected to the top of the fixed block 2, and the output end of the driving motor 11 passes through the top of the fixed block 2 and is fixedly connected to the top of the upper disc 6, a connecting rod 12 is fixedly connected between the upper disc 6 and the lower disc 7, and an inverted V-shaped plate 13 inclined to both sides is provided inside the grinding box 1 and above the grinding mechanism, and a discharge port 14 is opened in the middle of the inverted V-shaped plate 13, and an expansion mechanism for preventing the discharge port 14 from being stuck is provided in the grinding box 1, and the discharge port 14 is set to be a trumpet shape opened to both sides, and a dust suction mechanism is provided inside the rectangular frame 8;

[0029] The grinding mechanism includes a grinding motor 22, and a pair of grinding rollers 23 are rotatably connected to the inner side of the grinding box 1 and below the inverted V-shaped plate 13, the side walls of the grinding rollers 23 pass through the grinding box 1 and are fixedly connected to mutually meshing gears 24, the grinding motor 22 is fixedly connected to the side wall of the grinding box 1, and the output end of the grinding motor 22 passes through the inner side of the grinding box 1 and is fixedly connected to the side wall of one of the grinding rollers 23;

[0030] When the refractory raw material is ground, the refractory raw material transported by the conveyor belt falls into the feed hopper 10, and then accumulates at the upper opening 4 under its own gravity. At the same time, the driving motor 11 is controlled to start and drive the upper disc 6 to rotate, and then the lower disc 7 and the round rod 15 are driven to rotate at the same time under the action of the connecting rod 12, and then the top hole 9 on the upper disc 6 is rotated to the top of the rectangular frame 8, and then the rectangular frame 8 is driven, and the refractory raw material falls into the rectangular frame 8 under its own gravity, and then the top hole 9 is gradually rotated out of the top of the rectangular frame 8 through the continued rotation of the upper disc 6 (the rectangular frame 8 is not filled at this time, otherwise it will block the normal rotation of the upper disc 6. The above requirements can be met by setting the collection capacity of the rectangular frame 8 and the amount of refractory raw materials transported by the conveyor line);

[0031] Then, the upper disc 6 continues to rotate to drive the bottom hole 34 on the lower disc 7 to rotate below the rectangular frame 8, thereby removing the obstruction on the bottom of the rectangular frame 8, and the refractory raw material falls from the lower mouth 5 to the inverted V-shaped plate 13 under the gravity of the refractory raw material itself. At this time, the smaller refractory raw material directly passes through the discharge port 14 and falls onto the grinding roller 23. However, the larger refractory raw material will slide to both sides on the inverted V-shaped plate 13 until it falls from the corresponding discharge port 14 or falls from both sides of the inverted V-shaped plate 13 to the grinding roller 23, so that the incoming refractory raw material falls evenly on the grinding roller 23, avoiding the refractory raw material from falling in one place and affecting the grinding effect. At the same time, the grinding motor 22 is controlled to start and drive a grinding roller 23 to rotate, thereby driving one of the gears 24 to rotate, thereby driving the other gear 24 that is meshed with each other to rotate, and then driving the two grinding rollers 23 to rotate in the middle direction at the same time, so as to achieve the grinding effect of the fallen refractory raw material;

[0032] Finally, the driving motor 11 drives the upper disc 6 and the lower disc 7 to continue rotating, and the bottom hole 34 is completely rotated out of the upper part of the lower opening 5, and then the upper disc 6 and the lower disc 7 block the rectangular frame 8, so that the rectangular frame 8 is in a closed state. At this time, the dust collection mechanism is controlled to start by the reflector 31 and the infrared receiver 33 to completely absorb the dust in the rectangular frame 8, ensuring that the dust in the rectangular frame 8 will not spread out after opening. This process is repeated to avoid excessive dust from spreading out from the feed port during the feeding process, thereby avoiding affecting the surrounding environment and workers.

[0033] In order to improve the stability of the device during operation, both sides of the inner side of the top hole 9 are inclined to facilitate the upward squeezing of the refractory raw materials when the top hole 9 is rotated out of the rectangular frame 8, so as to avoid the refractory raw materials being stuck between the top hole 9 and the upper mouth 4 and affecting the normal operation of the device. The top of the inner side of the upper mouth 4 is inclined to facilitate the refractory raw materials falling into the upper mouth 4 to fall to the middle, thereby improving the stability during the feeding process. A feed hopper 10 is fixedly connected to the top of the fixed block 2. Through the setting of the feed hopper 10, the refractory raw materials falling from the conveyor belt are convenient to fall to the upper mouth 4, thereby further improving the stability during the feeding process.

[0034] In order to prevent the refractory raw materials from getting stuck at the discharge port 14 and affecting the normal operation of the device, the expansion mechanism includes a round rod 15, a pair of slide grooves 16 are provided at the top of the grinding box 1, and a top plate 17 is fixedly connected to the front and rear sides of the inverted V-shaped plate 13, and the top of the top plate 17 is slidably connected to the inner side of the slide groove 16, and a pair of springs 18 are fixedly connected between the inner side of the slide groove 16 and the top plate 17, the round rod 15 is fixedly connected to the bottom end of the lower disc 7, and the bottom of the round rod 15 passes through the top of the grinding box 1, and a pair of arc blocks 19 are staggered and fixedly connected to the outer wall of the round rod 15 up and down, and the arc blocks 19 and the rollers 21 are staggered to avoid the arc blocks 19 from squeezing to another roller 21 after rotating one circle, so as to avoid affecting the normal material guiding of the inverted V-shaped plate 13, and a fixed seat 20 is staggered and fixedly connected to the side close to the top plate 17 up and down, and a rotating groove 35 is provided on the side close to the fixed seat 20;

[0035] The inner side of the rotating groove 35 is rotatably connected with a roller 21, and the arc block 19 is set at a position where the bottom hole 34 of the round rod 15 can be squeezed to the roller 21 after being rotated out of the lower opening 5, ensuring that after the refractory raw materials in the rectangular frame 8 are discharged, the inverted V-shaped plate 13 is opened, and the positions of the arc blocks 19 are symmetrically arranged;

[0036] When the driving motor 11 drives the upper disc 6 and the lower disc 7 to rotate, it will also drive the bottom round rod 15 to rotate. Therefore, when the bottom hole 34 rotates from above the lower mouth 5, the arc block 19 on the outer wall of the round rod 15 will rotate to the side of the roller 21, and then gradually squeeze the roller 21 to push the fixed seat 20 to slide to the side away from it, and at the same time drive the top plate 17 to slide on the inner side of the slide groove 16, and gradually compress the spring 18, thereby driving the inverted V-shaped plate 13 to slide to the side away from it, so that the refractory raw material stuck at the discharge port 14 falls down, so as to avoid affecting the normal falling and grinding of the subsequent refractory raw materials. Subsequently, through the continued rotation of the round rod 15, the arc block 19 is rotated out of the roller 21, and then the squeezing of the roller 21 is gradually released. Under the elastic force of the spring 18, the inverted V-shaped plate 13 and the top plate 17 will be gradually pushed to reset, so that the inverted V-shaped plate 13 can be expanded after each material guiding is completed.

[0037] In order to prevent the refractory raw materials from falling through the gap between the grinding roller 23 and the grinding box 1, a plurality of spacer blocks 25 are fixedly connected to the inner side of the grinding box 1 and are equidistantly located beside the grinding roller 23. The setting of the plurality of spacer blocks 25 can serve as a barrier between the grinding roller 23 and the grinding box 1, thereby improving the grinding effect of the device.

[0038] In order to prevent the dust in the rectangular frame 8 from spreading out when the top hole 9 rotates to the top of the rectangular frame 8, the dust collection mechanism includes a dust collector 26, an inner wall of the circular groove 3 and a recessed groove 27 is provided next to the rectangular frame 8, a pair of dust collector heads 28 are fixedly connected to the inner side of the groove 27, and the side walls of the dust collector heads 28 are fixedly connected to the side walls of the fixed block 2 with connecting pipes 29, the dust collector 26 is fixedly connected to the top of the grinding box 1, and the other end of the connecting pipe 29 is fixedly connected to the suction end of the dust collector 26, and the air outlet end of the dust collector 26 is connected to the external dust treatment mechanism, and mounting grooves 30 are provided at the bottom of the upper disc 6 and on both sides of the top hole 9;

[0039] A reflector 31 is evenly connected to the inner side of the mounting groove 30, a support rod 32 is fixedly connected to the inner side of the circular groove 3, an infrared receiver 33 is fixedly connected to the top of the support rod 32, and the infrared receiver 33 is electrically connected to the vacuum cleaner 26 through a controller;

[0040] During the operation of the grinding equipment, through the arrangement of the reflective plate 31 and the infrared receiver 33, after the bottom hole 34 is rotated out of the upper part of the lower opening 5, the reflective plate 31 is rotated to the upper part of the infrared receiver 33, and the infrared rays emitted by the infrared receiver 33 are emitted to the reflective plate 31 and reflected back, and then the infrared receiver 33 collects the emitted infrared rays, and then transmits the signal to the controller to control the vacuum cleaner 26 of the dust collection mechanism to start, and then transmits the signal through the connecting pipe 29 to make the vacuum head 28 generate suction to absorb the dust inside the rectangular frame 8, so as to prevent the dust inside the rectangular frame 8 from spreading out when it is opened;

[0041] Then, when the top hole 9 is about to rotate to above the rectangular frame 8, another reflective plate 31 will rotate to above the infrared receiver 33. With the same principle as above, the infrared receiver 33 transmits the signal to the controller, and the controller controls the dust suction mechanism to close. Then, the top hole 9 rotates to above the rectangular frame 8, and the refractory raw material falls into the rectangular frame 8. This process is repeated to automatically absorb the dust inside the rectangular frame 8, thereby improving the convenience of the device.

[0042] The basic principles, main features and advantages of the present invention are shown and described above.

[0043] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
