Description

Technical Field

[0001] The utility model relates to the technical field of refractory brick recycling, and more specifically, to a crushing device for recycled refractory brick materials. Background Art

[0002] Refractory bricks are refractory materials with certain shapes and sizes. They can be divided into fired bricks, unfired bricks, fused-cast bricks (electro-fused bricks), and refractory insulation bricks according to the preparation process. They can be divided into standard bricks, ordinary bricks, special-shaped bricks, etc. according to their shapes and sizes. They can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical actions at high temperatures. Discarded refractory bricks can be crushed by a crushing device to complete the crushing of recycled refractory brick materials. The actual use has the advantages of simple operation, stable structure, and good use effect.

[0003] The prior art discloses a refractory brick waste crushing and recycling device with the publication number: CN220610782U, which includes a housing, a feeding port, a discharge chute, support columns, a crushing assembly, a first motor, a base rod, a connecting rod, crushing balls, a screening plate, screening holes, a grinding assembly, a placement plate, a second motor, a connecting column, grinding rollers, a collection box, a first handle, a connecting plate, brush bristles, cutting knives, a guide plate, a baffle, a collection cylinder, a filter screen, a vibrator, and a second handle. When using this device, first turn on the first motor. The first motor will drive the base rod to rotate, and then drive the connecting rod to rotate, thereby driving the crushing balls to rotate. Then turn on the two second motors and let both second motors rotate inward. The two second motors will drive the connecting column to rotate, and then drive the grinding rollers on the connecting column to rotate. Then put the refractory brick waste into the device through the feeding port. The crushing balls and cutting knives at the top will initially crush the refractory brick waste. Those that meet the crushing requirements will fall into the grinding assembly through the screening holes on the screening plate. The guide plate and baffle effectively ensure that all the refractory brick waste falls into the grinding assembly. The refractory brick waste is fully ground by the extrusion of the two grinding rollers. During the rotation of the grinding rollers, the brush bristles on both sides will clean the refractory brick waste remaining on the grinding rollers. The ground refractory brick waste will all fall above the filter screen. At this time, turn on the vibrator to screen the ground refractory brick waste. Finally, take out the collection box, the collection cylinder, and the filter screen through the first handle to obtain the screened refractory brick waste.

[0004] In the above-mentioned utility model, the feeding port is located at the upper part of the housing. Therefore, the recycled refractory brick materials on the ground need to be lifted to the feeding port by the operator before they can be put into the housing. This operation will increase the physical consumption of the operator. At the same time, the collection cylinder needs to be equipped with a vibrator to realize the vibration screening work of the filter screen. The installation of the vibrator will increase the input cost of this utility model.

[0005] In view of the problems in the related art, no effective solution has been proposed yet. Utility Model Content

[0016] Furthermore, four support seats are installed at the lower part of the outer shell.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present utility model provides a refractory brick recycled material crushing device, which has the following beneficial effects:

[0019] (1). The utility model adopts a conveying cylinder. When actually using the refractory brick recycled material crushing device, the operator pulls out the sealing cover by hand. At this time, the refractory brick recycled material can be put into the inside of the crushing cover through the through-hole of the sealing cover. After the addition of the refractory brick recycled material is completed, the sealing cover is reset, and then the control panel is used to make the driving motor and two servo motors work. The output ends of the two servo motors respectively drive two crushing rollers to rotate. The output end of the driving motor can drive the stirring shaft to rotate. The rotating stirring shaft drives the connecting shaft to rotate through two first belt pulleys and a first belt pulley. The rotating connecting shaft can drive the auger to rotate. At the same time, the rotating connecting shaft drives the transmission shaft to rotate through two second belt pulleys and a second transmission belt. The rotating transmission shaft can preliminarily crush the refractory brick recycled material through multiple cutting knives.

This feeding work does not require lifting the refractory brick recycled material on the ground to a relatively high height. Through the arranged conveying cylinder, the addition work of the refractory brick recycled material can be completed labor-saving and conveniently, improving the practicality of the refractory brick recycled material crushing device.

[0020] (2). The utility model adopts a filter screen. According to the above operation, the control panel can be used to make the two servo motors work. The output ends of the two servo motors can respectively drive two crushing rollers to rotate. The right crushing roller can drive the mounting shaft to rotate through two third belt pulleys and a third transmission belt. The rotating mounting shaft can drive the eccentric wheel to rotate. Since the gap length between the mounting shaft and the filter screen is greater than the length of the proximal end of the eccentric wheel and less than the length of the distal end of the eccentric wheel, during this process, the rotating eccentric wheel will intermittently impact the filter screen. When the filter screen moves downward, it can squeeze two telescopic springs through two mounting covers and two T-shaped rods. When the eccentric wheel disengages from the filter screen, the two telescopic springs act under their own elastic forces and can make the filter screen move upward through the two T-shaped rods and the two mounting covers. During this process, the filter screen moves up and down. The up-and-down shaking filter screen can screen the finally crushed refractory brick recycled material piled up on the upper part. Through the arranged filter screen, the screening work of the filter screen structure can be completed without adding a vibrator, reducing the input cost of the refractory brick recycled material crushing device.

[0037] In one embodiment, a control panel is installed on one side of the housing 1, and the control panel is electrically connected to the drive motor 4 and the two servo motors through wires.

Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0038] In one embodiment, four groups of support seats are installed at the lower part of the housing 1.

[0039] Working principle:

[0040] When actually using the refractory brick recycling material crushing device, the operator pulls out the sealing cover 23 by hand. At this time, the refractory brick recycling material can be put into the interior of the crushing cover 17 through the penetration of the sealing cover 23. After the addition of the refractory brick recycling material is completed, the sealing cover 23 is reset. Then, using the control panel, the driving motor 4 and two servo motors are operated. The output ends of the two servo motors drive two crushing rollers 35 to rotate respectively. The output end of the driving motor 4 can drive the stirring shaft 3 to rotate. The rotating stirring shaft 3 drives the connecting shaft 14 to rotate through two first belt pulleys 15 and the first belt pulley 15. The rotating connecting shaft 14 can drive the auger 25 to rotate. At the same time, the rotating connecting shaft 14 drives the transmission shaft 18 to rotate through two second belt pulleys 19 and the second transmission belt 20. The rotating transmission shaft 18 can initially crush the refractory brick recycling material through multiple cutting knives 22. The initially crushed refractory brick recycling material can enter the interior of the conveying cylinder 10 through the feed hopper 24. The rotating auger 25 can push the initially crushed refractory brick recycling material into the interior of the housing 1 through the guide pipe 21. The rotating stirring shaft 3 can re-crush the initially crushed refractory brick recycling material through multiple ball rods 5 and multiple crushing knives 6. The secondarily crushed refractory brick recycling material can fall between the two rotating crushing rollers 35 through the screen 7. The finally crushed refractory brick recycling material can fall into the interior of the screening frame 11. The refractory brick recycling material meeting the size requirements can fall into the interior of the collection box 12. This feeding work does not require lifting the refractory brick recycling material on the ground to a relatively high height. Through the provided conveying cylinder 10, the addition work of the refractory brick recycling material can be completed labor-saving and conveniently, improving the practicality of the refractory brick recycling material crushing device. At the same time, according to the above operations, it can be known that by using the control panel, the two servo motors can be operated, and the output ends of the two servo motors can drive the two crushing rollers 35 to rotate respectively. The right crushing roller 35 can drive the mounting shaft 31 to rotate through two third belt pulleys 33 and the third transmission belt 34. The rotating mounting shaft 31 can drive the eccentric wheel 32 to rotate. Since the gap length between the mounting shaft 31 and the filter screen 13 is greater than the length of the proximal end of the eccentric wheel 32 and less than the length of the distal end of the eccentric wheel 32. During this process, the rotating eccentric wheel 32 will intermittently impact the filter screen 13. When the filter screen 13 moves downward, it can squeeze two telescopic springs 28 through two mounting covers 30 and two T-shaped rods 29. When the eccentric wheel 32 disengages from the filter screen 13, the two telescopic springs 28, under the action of their own elastic forces, can make the filter screen 13 move upward through the two T-shaped rods 29 and the two mounting covers 30. During this process, the filter screen 13 moves up and down. The filter screen 13 that shakes up and down can screen the finally crushed refractory brick recycling material piled up on the upper part. Through the provided filter screen 13, the screening work of the filter screen structure can be completed without adding a vibrator, reducing the input cost of the refractory brick recycling material crushing device.
