[0002] Refractory materials are materials that have certain high-temperature resistance properties, do not undergo chemical reactions, do not expand, do not soften, and do not melt in high-temperature environments, and can maintain stable properties. They are widely used in metallurgy, building materials, chemical industry, power industry and other fields. The preparation steps of refractory materials generally include crushing, grinding and mixing raw materials, and then calcining or pressing them into different shapes.

[0003] For existing equipment used to prepare refractory materials, such as Figure 12 The apparatus shown, as well as an apparatus for preparing nano-corundum abrasives such as the one with announcement number CN222567875U, when crushing and grinding raw materials, lack a cleaning mechanism to clean the crushing and grinding structure or the inner wall of the shell, which easily leads to the raw materials adhering to the crushing or grinding structure, resulting in insufficient utilization of raw materials and waste of resources. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a low-carbon and environmentally friendly refractory material preparation device. By designing a raw material processing component, the device grinds the raw materials fed into the grinding chamber using a grinding element combined with a screen, and cleans the powdery raw materials adhering to the grinding element or screen using a cleaning mechanism. This device has the advantages of high raw material utilization, ease of use, and simple structure.

[0005] The main idea of ​​the technical solution adopted by this utility model is as follows: a raw material processing component is designed, a screen is set at the bottom of the grinding chamber, and the raw materials are ground by a grinding component that can be driven by a drive component. During the grinding process, the surface of the grinding component is cleaned by the first brush on both sides of the grinding component, and the inner wall of the grinding chamber is cleaned by the second brush located at the far end of the grinding component. The screen is cleaned by the third brush and the inner wall of the feeding chamber is cleaned by the fourth brush to prevent the raw materials from adhering and improve the material utilization rate.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A low-carbon and environmentally friendly refractory material preparation device includes a shell and a collection chamber. The top of the shell is provided with a feeding port. The shell is provided with a raw material processing component for grinding the raw materials of the refractory material. The bottom of the shell is also provided with a post-processing component.

[0008] The raw material processing assembly includes a grinding mechanism and a cleaning mechanism that can be driven by a drive component.

[0009] Based on the above technical solution, the grinding mechanism further includes a grinding chamber opened at the top of the housing, and a grinding roller horizontally fixed on the power shaft of the drive component. A screen is fixed at the bottom of the grinding chamber, which can just contact the lowest point of the grinding roller.

[0010] Based on the above technical solution, the cleaning mechanism further includes a fixed frame fixed on the drive shaft of the drive component, a first brush body symmetrically arranged on the fixed frame for cleaning the grinding roller, and a second brush body vertically arranged at the end of the fixed frame away from the drive component for cleaning the inner wall of the grinding chamber.

[0011] Based on the above technical solution, it further includes a feeding chamber located below the grinding chamber. The power shaft of the drive unit is also provided with a fixing rod on the shaft of the feeding chamber. The top of the fixing rod is provided with a third brush body for cleaning the screen. The end of the fixing rod away from the drive unit is also provided with a fourth brush body for cleaning the inner wall of the feeding chamber.

[0012] Based on the above technical solution, further, the discharge port at the bottom of the feeding chamber is directly opposite the top of the collection chamber, and the diameter of the discharge port at the bottom of the feeding chamber is smaller than the minimum width of the collection chamber.

[0013] Based on the above technical solution, a telescopic component is further fixed at the bottom of the power shaft of the drive component, and a stirring rod is fixed at the bottom of the telescopic component. The stirring rod can extend into or move out of the collection chamber when the telescopic component extends or retracts.

[0014] The post-processing component includes a first outlet and a second outlet on both sides of the housing.

The second outlet is also provided with a pressing component for pressing the raw materials collected in the collection chamber.

[0015] The beneficial effects of this utility model are:

[0016] In use, this invention drives a grinding roller to rotate, which, in conjunction with a screen, grinds the raw materials fed into the grinding chamber. The particle size of the raw materials is ground to a size that allows them to pass through the sieve holes. A stirring rod at the bottom stirs the raw materials in the collection chamber for subsequent pressing or other post-processing. During this process, a first brush cleans the surface of the grinding roller, a second brush cleans the side walls of the grinding chamber, a third brush cleans the raw materials adhering to the screen, and a fourth brush cleans the side walls of the feeding chamber, preventing material adhesion during grinding and thus improving raw material utilization.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] The inventors discovered that existing devices for preparing refractory materials often lack a cleaning mechanism for the crushed or ground structure during the crushing and grinding process, leading to the raw materials adhering to the crushed or ground structure and resulting in insufficient utilization of the raw materials.

[0032] Based on the above findings, this application proposes a low-carbon and environmentally friendly refractory material preparation device. By designing a raw material processing component, a screen is installed at the bottom of the grinding chamber, and grinding components driven by a drive unit grind the input raw materials. During grinding, first brushes on both sides of the grinding components clean the surface of the grinding components, and a second brush located at the far end of the grinding components cleans the inner wall of the grinding chamber. A third brush cleans the screen, and a fourth brush cleans the inner wall of the feeding chamber, preventing raw material adhesion and improving material utilization. This device has the advantages of high raw material utilization, ease of use, and simple structure.

[0033] See Figures 1-3This application discloses a low-carbon and environmentally friendly refractory material preparation device, including a shell 1. In some embodiments, the shell 1 is a hollow cylindrical structure, and its material should be a metal material with high strength. The shell 1 can be divided into three parts: an upper grinding chamber 3021, a middle feeding chamber 3034, and a lower post-processing chamber. The upper grinding chamber 3021 is provided with a feeding port 101 for feeding raw materials for refractory material preparation, and a sealing cover structure is also provided at the feeding port 101.

[0034] See Figures 4-6 Specifically, a raw material processing component 3 is provided in the grinding chamber 3021 above the housing 1. The raw material processing component 3 can be divided into a grinding mechanism 302 and a cleaning mechanism 303. A driving component 301 is provided at the top center of the housing 1. In one embodiment of the present invention, the driving component 301 is a drive motor with its power shaft vertically downward and passing through the top of the housing 1 and the grinding chamber 3021 in sequence, until it extends into the feeding chamber 3034. The driving component 301 can drive the grinding mechanism 302 to grind the raw materials fed into the grinding chamber 3021, and the cleaning mechanism 303 can clean the powdery raw materials that adhere to the grinding mechanism 302 or the side wall of the housing 1 during grinding. It should be noted that the raw materials targeted by the grinding mechanism 302 are crushed raw materials, that is, the raw materials contain most of the powder and some blocky materials.

[0035] See Figures 8-11The grinding mechanism 302 includes horizontally arranged grinding rollers 3022, meaning the roller body of the grinding roller 3022 is perpendicular to the shaft of the driving member 301. A screen 3023, accessible to the lowest point of the grinding roller 3022, is located at the bottom of the grinding chamber 3021. In one embodiment, the grinding rollers 3022 are made of a high-strength metal material. Both grinding rollers 3022 are connected to the shaft of the driving member 301 via two fixing frames 3031. The fixing frame 3031 is a cuboid-like frame structure with a cavity in the middle and no top or bottom. One end is fixed to the shaft of the driving member 301 in a centrally symmetrical manner by insertion or welding. The grinding rollers 3022 are rotatably fixed to the fixing frame 3031 by insertion of a rotating shaft. Inside the central cavity, the screen 3023 is a metal mesh structure with fine sieve holes. It is fixed to the annular fixing frame at the edge of the shell 1 and multiple connecting rods extending from the fixing frame towards the center by welding or bolting. When raw materials are put into the grinding chamber 3021, the fixing frame 3031 can be rotated by the drive component 301, which can drive the grinding roller 3022 and the upper surface of the screen 3023 to rotate, so as to grind the raw materials. The particle size of the raw materials is ground to be able to pass through the fine sieve holes on the screen 3023, so as to facilitate the subsequent mixing of materials. After grinding and sieving, the raw materials fall vertically and are gathered towards the center by the feeding chamber 3034, and then flow into the collection chamber 2 located below the shell 1 and directly opposite the bottom outlet of the feeding chamber 3034.

[0036] See Figure 7 When the grinding roller 3022 and the screen 3023 grind the raw material, some raw material powder may be squeezed and adhered to the screen holes of the screen 3023 due to the action of the grinding roller 3022. It may also adhere to the side wall of the housing 1. So while the driving member 301 drives the grinding roller 3022 to grind, the cleaning mechanism 303 is also needed to clean the adhered raw material.

[0037] In one embodiment, the cleaning mechanism 303 includes a first brush body 3032 fixed to two fixed frames 3031. The first brush body 3032 is horizontally arranged on both sides of the middle part of the fixed frame 3031 and can just contact the surface of the grinding roller 3022. When the grinding roller 3022 rotates, the fine bristles on the first brush body 3032 can scrape and clean the powdery raw materials adhering to its surface. At the same time, a second brush body 3033 is also vertically fixed at the end of the fixed frame 3031 away from the drive member 301. The second brush body 3033 is distributed with fine bristles with an overall length close to the length of the grinding chamber 3021, which can clean the powder adhering to the inner wall of the grinding chamber 3021 when the fixed frame 3031 rotates.

[0038] Secondly, see Figure 7A fixing rod 3035 is also provided on the power shaft extending from the drive component 301 to the feeding chamber 3034 by means of welding or bolt connection. The fixing rod 3035 is a high-strength metal rod, including a horizontal section and a vertical section. A third brush body 3036 is provided above the horizontal section. The third brush body 3036 can contact the bottom of the screen 3023. In some embodiments, the bristles of the third brush body 3036 can extend into the screen holes of the screen 3023, thereby removing the bristles that adhere to the bottom of the screen 3023 or the screen holes. The powdery raw materials inside are scraped off; a fourth brush body 3037 is fixed on the vertical section of the fixed rod 3035. The fourth brush body 3037 can scrape off the powdery raw materials adhering to the vertical inner wall of the feeding chamber 3034, so that the powder brushed off by the grinding, sieving and cleaning mechanism 303 can converge towards the center through the conical side and be sent into the collection chamber 2 through the discharge port at the center of the bottom of the feeding chamber 3034. The overall size of the discharge port of the feeding chamber 3034 is smaller than that of the collection chamber 2, which can prevent the raw material powder from falling outside the collection chamber 2.

[0039] In some embodiments, a telescopic member 304 is fixed to the bottom of the drive member 301 by welding or bolting. A stirring rod 305 is fixed to the bottom of the telescopic member 304. The telescopic member 304 is used to adjust the horizontal height of the stirring rod 305. The telescopic member 304 is an electric telescopic rod, and its length can be adjusted manually, so that the stirring rod 305 can extend into the collection chamber 2. When the collection chamber 2 is filled with raw material powder, the drive member 301 can drive the telescopic member 304 and the stirring rod 305 to rotate, so as to stir the powder in the collection chamber 2. After stirring, the telescopic member 304 is shortened, so as to remove the stirring rod 305 from the collection chamber 2 for subsequent removal of the collection chamber 2 or for post-processing.

[0040] In some embodiments, a post-processing assembly 4 is further provided in the post-processing compartment located at the lower part of the shell 1. The post-processing assembly 4 includes a first outlet 401 and a second outlet 402 opened on both sides of the post-processing compartment. A conveyor 403 is provided in the post-processing compartment, passing through the first outlet 401 and the second outlet 402. The conveyor 403 can be a conveyor belt structure, capable of transporting the collection compartment 2 located in its middle to the first outlet 401 or the second outlet 402. At the second outlet 402, a horizontal fixing plate is provided. The method involves a fixed pressing component 404, which can be either a pressing machine or a hydraulic press. After the collection chamber 2 is sent out from the second outlet 402, it can be pressed vertically downward into the collection chamber 2 by the pressing plate at the bottom of the pressing component 404. During pressing, a binder that facilitates forming can be added to the collection chamber 2 to press the ground refractory powder into block-shaped refractory material. After the collection chamber 2 is sent out from the first outlet 401, the operator can remove the collection chamber 2 to further process the powdered refractory material through other methods.

[0041] In some implementations, a controller device may be provided outside the housing 1 to control the opening and closing of the drive member 301, the telescopic member 304 and the transmission member 403 respectively, thereby further improving the usability of this utility model.

[0042] Specific application examples

[0043] The operator opens the sealing cover of the feeding port 101 and adds the refractory raw materials that have undergone preliminary crushing into the grinding chamber 3021. Then, the sealing cover is installed and the drive unit 301 is turned on.

[0044] The drive unit 301 drives the grinding roller 3022 to grind the raw material. The powdered raw material falls through the screen 3023, is gathered to the center through the feeding chamber 3034, and then falls into the collection chamber 2.

[0045] When the drive unit 301 is turned on, the multiple brushes on the cleaning mechanism 303 scrape and clean the raw material powder adhering to the surface of the grinding roller 3022, the inner wall of the grinding chamber 3021, the screen 3023 and the inner wall of the feeding chamber 3034, and the powder falls into the collection chamber 2.

[0046] During grinding, the operator can control the extension of the telescopic component 304 to allow the stirring rod 305 to extend into the collection chamber 2 to stir the raw material powder, so that the raw material powder is evenly distributed.

[0047] After the raw materials have completely fallen into the collection chamber 2, the drive unit 301 is turned off and the telescopic unit 304 is shortened. Then, the collection chamber 2 is transported out from the first outlet 401 or the second outlet 402 by the conveyor 403. The operator can manually control the conveyor 403 to transport the collection chamber 2 to the bottom of the pressing unit 404 and control the pressing unit 404 to press the raw material powder in the collection chamber 2 into block refractory material.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
