[0024] See also Figure 1-6 The utility model provides a technical solution: a screening device for refractory materials, comprising: a base 1, four ends of the bottom of the base 1 are equipped with legs 101, a screening box 2 is embedded in the surface of the base 1, a screening device 3 is arranged in the inner cavity of the screening box 2, three fixing components 4 are arranged on both sides of the screening device 3, three screening mesh plates 5 are movably installed inside the screening device 3, and slots 501 are opened at one end of both sides of the three screening mesh plates 5.

[0025] Specifically: four legs 101 support the base 1, and the screening box 2 is fixedly embedded in the surface of the base 1. After the refractory material is poured into the screening box 2, the refractory material can be screened by controlling the screening device 3. The refractory material can be screened in multiple stages through the three screening meshes 5, and the screening holes opened on the surfaces of the three screening meshes 5 become smaller from top to bottom, so that refractory materials of different particle sizes can be screened, which can improve the screening efficiency. The screening mesh 5 can be fixedly placed in the screening device 3 through the fixing component 4, so that the screening mesh 5 can be disassembled for later cleaning, and the screening mesh 5 can be disassembled and replaced conveniently.

[0026] In one embodiment, a control terminal 201 is installed on one side of the screening box 2, a switch door 202 is installed on the surface of the screening box 2 through a hinge, a handle 203 is installed on the surface of the switch door 202, a discharge bin 204 is installed at the bottom of the screening box 2, a feed bin 205 is embedded in the top of the screening box 2, a cover plate 206 is movably installed on the top of the feed bin 205, a handle 207 is installed on the surface of the cover plate 206, and two movable grooves 208 are provided on both sides of the inner wall of the screening box 2.

[0027] Specifically: the control terminal 201 is electrically connected to each electrically controlled device, and the switch door 202 can be opened using the handle 203. At this time, the interior of the screening box 2 can be easily cleaned, and the screening mesh plate 5 can be disassembled and replaced. The refractory material to be screened can be poured from the inside of the feed bin 205, and the refractory material can be vibrated and screened by the screening device 3. The screened refractory material can be discharged from the discharge bin 204, and then discharged into the collection trough placed under the discharge bin 204. When the refractory material is being screened, the handle 207 can be used to cover the cover plate 206 on the top of the feed bin 205 to prevent dust generated during the screening process from flying out. The movable groove 208 on the inner wall of the screening box 2 facilitates the screening device 3 to vibrate and screen the refractory material.

[0028] In one embodiment, the screening device 3 includes two vibration motors 301, and L-shaped support plates 302 are installed on the top of the two vibration motors 301, two springs 1 303 are installed on the top of one side of the two L-shaped support plates 302, and the four springs 1 303 are evenly divided into two groups, and the bottom ends of the two groups of springs 1 303 are installed with fixed plates 304, and both sides of the two fixed plates 304 are connected to both sides of the inner wall of the screening box 2, and support plates 1 305 are installed on one side of the top of the two L-shaped support plates 302, and mounting plates 306 are installed on one side of the two L-shaped support plates 302, and support plates 2 307 are installed on one side of the two mounting plates 306, and connecting plates 308 are installed on one end of the opposite side of the two L-shaped support plates 302, and three card slots 309 are provided on the surface of one side of the two L-shaped support plates 302.

[0029] Specifically: two vibration motors 301 can be started through the control terminal 201, and the operation of the two vibration motors 301 can drive the two L-shaped support plates 302 to vibrate. Since the two L-shaped support plates 302 are connected by the connecting plate 308, the two L-shaped support plates 302 can perform synchronous vibration screening under the action of four springs 1 303. The four springs 1 303 can shake and rebound the L-shaped support plates 302 during the vibration of the vibration motor 301. The two fixed plates 304 are used to support the installation springs 1 303. When the L-shaped support plates 302 are driven to vibrate by the vibration motor 301, the support plates 1 305 on one side of the two L-shaped support plates 302 also shake. The two support plates 1 305 are used to support and limit the two L-shaped support plates 302. The support plates 2 307 on one side of the two mounting plates 306 are also supported and limited. The card slots 309 provided on the surfaces of the L-shaped support plates 302 are used to movably install the screening mesh plate 5.

[0030] In one embodiment, the two support plates 1 305 and the two support plates 2 307 are both movable inside the four movable slots 208 .

[0031] Specifically: when the two vibration motors 301 drive the two L-shaped support plates 302 to vibrate, the two support plates 1 305 and the two support plates 2 307 are all located inside the four movable grooves 208. At this time, the positions of the two L-shaped support plates 302 can be supported and limited, which can prevent the entire screening device 3 from tilting and shifting during operation.

[0032] In one embodiment, the fixing assembly 4 includes a spring 401, which is fixedly connected to the surface of the L-shaped support plate 302. A fixing disk 402 is installed at one end of the spring 401, and an insertion rod 403 is installed on one side of the fixing disk 402. The insertion rod 403 is movably embedded in the surface of the L-shaped support plate 302, and the insertion rod 403 is located on the inner side of the spring 401. The insertion rod 403 moves inside the card slot 309 and the slot 501.

[0033] Specifically: when the screening screen plate 5 is disassembled and replaced, the fixing plate 402 can be manually pulled, so that the fixing plate 402 drives the insertion rod 403 on one side to be pulled out. Since one side of the fixing plate 402 is connected to the L-shaped support plate 302 through the spring 2 401, the insertion rod 403 will not be easily disengaged when it is located inside the slot 501 for limiting, and the insertion rod 403 can be easily rebounded and placed under the action of the spring 2 401, and one end of the insertion rod 403 can be inserted into the slot 501 to fix the placement of the screening screen plate 5.

[0034] In one embodiment, the six slots 309 are evenly divided into three groups, and the three screening screens 5 are movable inside the three groups of slots 309 .

[0035] Specifically: the size of the slot 309 allows the screening mesh plate 5 to be placed therein. When the screening mesh plate 5 is to be disassembled more smoothly, the screening mesh plate 5 can be manually pulled out from the inside of the slot 309, and then fixed by the fixing component 4 after replacement, which is more convenient.

[0036] Working principle: The vibration motor 301 is electrically connected to the control terminal 201. When the refractory material is screened, the refractory material can be poured in through the feed bin 205, and the cover plate 206 is covered on the top of the feed bin 205 using the handle 207. At this time, the refractory material can fall along the inside of the feed bin 205 to the surface of the first screening mesh plate 5. The two vibration motors 301 can be started through the control terminal 201. The operation of the two vibration motors 301 can drive the two L-shaped support plates 302 to vibrate. At this time, the three screening mesh plates 5 on the opposite sides of the two L-shaped support plates 302 will shake up and down, and the surface of the first screening mesh plate 5 The refractory materials can be screened downward through the multiple screening holes opened on the surface of the screening mesh plate 5. The first screening mesh plate 5 can screen out the refractory materials with larger particle sizes. The screened refractory materials can then fall onto the surface of the second screening mesh plate 5. At this time, the refractory materials continue to be filtered downward through the screening holes on the surface of the second screening mesh plate 5, so that the screened refractory materials fall onto the surface of the third screening mesh plate 5. At this time, the refractory materials continue to be screened through the screening holes opened on the surface of the third screening mesh plate 5, and finally the refractory materials that meet the screening criteria can be screened out. At this time, the screened refractory materials are finally discharged to the lower storage bin 204 through the discharge bin 204. In the collecting tank, the screening holes opened on the surfaces of the three screening mesh plates 5 can be used for screening refractory materials of different particle sizes. By setting the screening device 3, the refractory materials can be screened in multiple stages, which can facilitate the screening of relatively fine refractory materials and improve the screening efficiency. After the screening is completed, the switch door 202 can be opened by using the handle 203, and the refractory materials accumulated on the surfaces of the three screening mesh plates 5 can be taken out. When the screening mesh plates 5 need to be disassembled and replaced, the two fixed disks 402 on both sides of the screening mesh plates 5 can be manually pulled out, so that the fixed disks 402 can drive the insertion rod 403 to be separated from the interior of the slot 501, and the screening mesh plates 5 can be removed. It is pulled out from the inside of the slot 309. When the screening holes on the surface of the screening mesh plate 5 are cleaned or a new screening mesh plate 5 is replaced, the screening mesh plate 5 is placed in its original position through the slot 309, and the insertion rod 403 is driven by the fixing plate 402 to rebound under the action of the spring 401 and placed inside the slot 501. At this time, both sides of the screening mesh plate 5 are fixed and limited by two insertion rods 403, so that the screening mesh plate 5 will not easily fall off when vibrating. By arranging the screening mesh plate 5 to be easy to disassemble, the screening mesh plate 5 can be easily cleaned after the refractory material screening is completed, and the screening mesh plate 5 can be conveniently disassembled and replaced, which is more practical.
