Description

Technical Field

[0001] This utility model relates to the technical field of carbon brick cutting equipment, specifically a special cutting equipment for carbon brick lining. Background Technology

[0002] In industrial kilns such as blast furnaces and hot blast stoves in industries like metallurgy and chemicals, carbon bricks are widely used as lining materials for critical components due to their excellent high-temperature resistance, erosion resistance, and high thermal stability. During actual construction, carbon bricks need to be cut and processed on-site to meet the dimensional requirements of the masonry work.

[0003] Currently, carbon brick cutting is typically done by operators using handheld angle grinders or simple cutting platforms. Carbonaceous materials are hard and brittle; during high-speed cutting, the intense friction between the cutting disc and the carbon brick generates a large amount of extremely fine carbon dust particles. This dust not only severely pollutes the working environment but also poses a significant health threat to the respiratory system of operators. Long-term inhalation of carbon dust can lead to occupational diseases such as pneumoconiosis, presenting a significant safety hazard.

[0004] Existing technologies still have shortcomings in use: When traditional carbon brick lining cutting equipment removes the dust generated, it usually uses a dust suction head placed above or to the side of the cutting blade. Since the high-speed rotating cutting blade will throw the dust outward, relying solely on the dust suction head will still cause most of the dust to escape, resulting in poor dust removal effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a special cutting device for carbon brick lining. During the cutting process, it can isolate most of the dust inside and absorb the generated dust, which greatly reduces the dust emission and improves the dust removal effect, and can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special cutting device for carbon brick lining, comprising a carbon brick cutting table and a support frame disposed on the carbon brick cutting table. A carbon brick cutting assembly is disposed on the support frame, and a carbon brick clamping assembly is disposed on the carbon brick cutting table. Two corresponding dust shields are disposed on the carbon brick clamping assembly, with the two dust shields located on opposite sides of the carbon brick cutting assembly. A dust suction head is disposed inside each dust shield, and the dust suction head has uniformly spaced suction holes on one side opposite the carbon brick cutting assembly. A hard dust removal tube is disposed on the dust suction head and communicates with the interior of the dust suction head. The hard dust removal tube penetrates the dust shield, and the ends of the two hard dust removal tubes are connected to a flexible dust removal hose. A connecting pipe is disposed on the flexible dust removal hose and communicates with the interior of the flexible dust removal hose. The connecting pipe is made of a rigid material.A PLC controller is installed on the support plate. The input end of the electric telescopic rod is electrically connected to the output end of the PLC controller, and the input end of the motor is also electrically connected to the output end of the PLC controller. The carbon brick to be cut is placed on the carbon brick cutting table, positioned between two clamping bars. The height of the clamping bars is equal to the thickness of the carbon brick. Holding the handle, the turntable rotates clockwise, causing the bidirectional screw to rotate. Since the bidirectional screw is threadedly connected to the clamping bars, it causes the two clamping bars to move towards each other. The two clamping bars, in turn, cause the two dust shields to move towards each other until... While clamping the carbon brick, two dust shields also come together, connecting the connecting pipe to the external dust collection device. The external dust collection device operates, and the PLC controller is activated. The PLC controller controls the motor's output shaft to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the cutting disc to rotate. The PLC controller also controls the extension end of the electric telescopic rod to extend downwards. The electric telescopic rod, through the lifting block and mounting plate, drives the rotating shaft downwards, which in turn drives the cutting disc downwards. As the cutting disc moves downwards, it gradually cuts the carbon brick until it is completely cut. Afterwards, the PLC controller stops the motor and controls the telescopic end of the electric telescopic rod to retract upwards, causing the cutting disc to move upwards. During the cutting process, a large amount of dust is generated. Two dust shields and two baffles can isolate most of the dust inside, greatly reducing dust escape. Because there is a small gap between the cutting disc and the movable grooves on the baffles, it does not affect the suction head's ability to collect dust inside the dust shields. The generated dust passes sequentially through the suction head, the hard dust removal pipe, the soft dust removal hose, and the connecting pipe into the external dust collection device. This completes the dust removal process. When it is necessary to remove the cut carbon brick, hold the handle and use it to drive the turntable to rotate in the opposite direction. The turntable drives the double-headed screw to rotate in the opposite direction, and the double-headed screw drives the two clamping bars to gradually move away from each other until the two clamping bars are completely separated from the carbon brick. Then the cut carbon brick can be removed. Some dust will fall into the dust collection box through the cutting groove for collection. When it is necessary to clean the dust inside the dust collection box, first open the latch of the movable door to open the movable door and facilitate the cleaning of the dust inside the dust collection box.

[0007] Furthermore, the carbon brick cutting assembly is a support plate mounted on a support frame. An electric telescopic rod is vertically mounted on the lower surface of the support plate. A lifting block is mounted at the lower telescopic end of the electric telescopic rod. A mounting plate is vertically mounted on the lower surface of the lifting block. A cutting disc is rotatably mounted on the mounting plate via a rotating shaft. A motor is mounted on the outer side of the mounting plate via a fixed plate, and the motor's output shaft is fixedly connected to the rotating shaft. A cutting slot corresponding to the cutting disc is formed on the upper surface of the carbon brick cutting table. The support plate supports the electric telescopic rod. The telescopic end of the electric telescopic rod drives the lifting block to move up and down. The lifting block drives the mounting plate to move up and down. The mounting plate drives the cutting disc to move up and down via the rotating shaft. The motor's output shaft drives the cutting disc to rotate via the rotating shaft, thereby enabling the cutting of the carbon brick.

[0008] Furthermore, each of the two dust shields is equipped with a baffle plate that cooperates with the lifting block. The baffle plate has a movable groove that cooperates with the cutting disc. During the up-and-down movement of the lifting block within the dust shield, a large gap will be generated between the lifting block and the dust shield. The baffle plate on the dust shield can greatly reduce the gap, and the movable groove on the baffle plate allows the cutting disc to move up and down.

[0009] Furthermore, a stabilizing column is vertically mounted on the lifting block, and the stabilizing column passes through a through hole in the support plate. The stabilizing column enhances the stability of the lifting block when it moves up and down.

[0010] Furthermore, the carbon brick clamping assembly consists of two corresponding fixing blocks mounted on the upper surface of the carbon brick cutting table. Two corresponding clamping strips are movably arranged between the two fixing blocks, and each clamping strip is connected to the lower end of a dust shield. The outer side of the dust shield away from the cutting disc is flush with the outer side of the clamping strip away from the cutting disc. Each clamping strip has a moving groove corresponding to the cutting disc. A guide post and a bidirectional screw are horizontally arranged between the two fixing blocks, penetrating the clamping strips. The two ends of the bidirectional screw are threaded to the two clamping strips through two sections of oppositely oriented rotating threads, and the bidirectional screw is rotatably connected to the fixing blocks via bearings. Rotating the bidirectional screw in both directions moves the two clamping strips along the guide post in opposite directions, thereby clamping or releasing the carbon brick.

[0011] Furthermore, a turntable is provided at the end of the bidirectional screw, and a handle is provided at an eccentric position on the side of the turntable. The turntable increases the rotation radius, requiring less effort compared to directly rotating the bidirectional screw, and the handle facilitates rotation of the turntable.

[0012] Furthermore, the lower surface of the carbon brick cutting table is provided with a dust collection box that corresponds to the cutting groove. A movable door is hinged to one end of the dust collection box, and a latch is provided on the movable door. The dust collection box can collect dust falling down from the cutting groove, further reducing the spread of dust. The movable door can be opened from the dust collection box to facilitate cleaning the dust inside the dust collection box.

[0013] Furthermore, a pipe support rod corresponding to the connecting pipe is vertically installed on the upper surface of the carbon brick cutting table, and the connecting pipe passes through the pipe support rod. The pipe support rod can support the connecting pipe.

[0014] Based on the above technical solution, the beneficial effects achieved by this utility model's special cutting equipment for carbon brick lining through practical application are as follows: This invention utilizes the cooperation between a lifting block, a dust shield, and a baffle plate. By rotating a bidirectional screw, the clamping bar moves along the guide column. While clamping the carbon brick, the clamping bar also causes the two dust shields to come together. At the same time, the baffle plate blocks any large gaps in the lifting block's up-and-down movement within the dust shield, greatly reducing the gaps and minimizing dust escape. Furthermore, the cooperation between the suction head, dust removal hard pipe, dust removal soft pipe, connecting pipe, and external suction device can absorb most of the dust trapped inside the dust shield, improving the dust removal effect.

Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7This embodiment provides a technical solution: a special cutting device for carbon brick lining, including a carbon brick cutting table 1 and a support frame 2 set on the carbon brick cutting table 1. The support frame 2 is provided with a carbon brick cutting component, and the carbon brick cutting table 1 is provided with a carbon brick clamping component. The carbon brick clamping component is provided with two corresponding dust shields 16, and the two dust shields 16 are respectively located on both sides of the carbon brick cutting component. A dust suction head 26 is provided inside the dust shield 16. The dust suction head 26 has uniformly opened dust suction holes on one side opposite the carbon brick cutting component. A dust removal hard pipe 20 is provided on the dust suction head 26, and the dust removal hard pipe 20 communicates with the inside of the dust suction head 26. The dust removal hard pipe 20 passes through the dust shield 16. The ends of the two dust removal hard pipes 20 are connected to the dust removal hose 19. A connecting pipe 24 is provided on the dust removal hose 19, and the connecting pipe 24 communicates with the inside of the dust removal hose 19. The connecting pipe 24 is made of rigid material.A PLC controller is installed on the support plate 3. The input end of the electric telescopic rod 5 is electrically connected to the output end of the PLC controller, and the input end of the motor 8 is also electrically connected to the output end of the PLC controller. The carbon brick to be cut is placed on the carbon brick cutting table 1, so that the carbon brick is between the two clamping bars 15. The height of the clamping bars 15 is equal to the thickness of the carbon brick. Hold the handle 10, and the handle 10 drives the turntable 11 to rotate in the forward direction. The turntable 11 drives the bidirectional screw 14 to rotate. Since the bidirectional screw 14 is threadedly connected to the clamping bars 15, the bidirectional screw 14 drives the two clamping bars 15 to move towards each other. The two clamping bars 15 drive the two dust shields 16 to move towards each other. Move until the two clamping bars 15 clamp the carbon brick, and at the same time the two dust shields 16 are also closed together. Connect the connecting pipe 24 to the external dust collection device. The external dust collection device is activated, and the PLC controller is turned on. The PLC controller controls the output shaft of the motor 8 to rotate. The output shaft of the motor 8 drives the rotating shaft to rotate, and the rotating shaft drives the cutting disc 9 to rotate. The PLC controller controls the telescopic end of the electric telescopic rod 5 to extend downward. The electric telescopic rod 5 drives the rotating shaft to move downward through the lifting block 6 and the mounting plate 7. The rotating shaft drives the cutting disc 9 to move downward. During the downward movement, the cutting disc 9 gradually cuts the carbon brick until the carbon brick is completely cut. The LC controller stops the motor 8, and the PLC controller shortens the extension end of the electric telescopic rod 5, causing the cutting disc 9 to move upward. During the cutting process, a large amount of dust is generated. The two dust shields 16 and two baffles 17 can isolate most of the dust inside, greatly reducing dust dispersion. Because there is a small gap between the cutting disc 9 and the movable grooves 25 on the baffles 17, it does not affect the suction head 26's suction inside the dust shield 16. The generated dust passes sequentially through the suction head 26, the dust removal rigid pipe 20, the dust removal flexible pipe 19, and the connecting pipe 24 into the external suction device, thus completing the process. For dust removal, when it is necessary to remove the cut carbon brick, hold the handle 10. The handle 10 drives the turntable 11 to rotate in the opposite direction. The turntable 11 drives the double-sided screw 14 to rotate in the opposite direction. The double-sided screw 14 drives the two clamping bars 15 to gradually move away from each other until the two clamping bars 15 are completely separated from the carbon brick. Then the cut carbon brick can be removed. Some dust falls into the dust collection box 22 through the cutting groove 21 for collection. When it is necessary to clean the dust inside the dust collection box 22, first open the latch of the movable door 23 to open the movable door 23, which makes it convenient to clean the dust inside the dust collection box 22.

[0025] Furthermore, the carbon brick cutting assembly consists of a support plate 3 mounted on a support frame 2. An electric telescopic rod 5 is vertically mounted downwards on the lower surface of the support plate 3. A lifting block 6 is mounted at the lower telescopic end of the electric telescopic rod 5. A mounting plate 7 is vertically mounted on the lower surface of the lifting block 6. A cutting disc 9 is rotatably mounted on the mounting plate 7 via a rotating shaft. A motor 8 is mounted on the outer side of the mounting plate 7 via a fixed plate, and the output shaft of the motor 8 is fixedly connected to the rotating shaft. A cutting slot 21 corresponding to the cutting disc 9 is formed on the upper surface of the carbon brick cutting table 1. The support plate 3 supports the electric telescopic rod 5. The telescopic end of the electric telescopic rod 5 drives the lifting block 6 to move up and down. The lifting block 6 drives the mounting plate 7 to move up and down. The mounting plate 7 drives the cutting disc 9 to move up and down via a rotating shaft. The output shaft of the motor 8 drives the cutting disc 9 to rotate via the rotating shaft, thereby cutting the carbon brick.

[0026] Furthermore, each of the two dust shields 16 is equipped with a baffle plate 17 that cooperates with the lifting block 6. The baffle plate 17 has a movable groove 25 that cooperates with the cutting disc 9. During the up-and-down movement of the lifting block 6 within the dust shield 16, a large gap will be generated between the lifting block 6 and the dust shield 16. The baffle plate 17 provided on the dust shield 16 can greatly reduce the gap, and the movable groove 25 on the baffle plate 17 allows the cutting disc 9 to move up and down.

[0027] Furthermore, a stabilizing column 4 is vertically installed on the lifting block 6, and the stabilizing column 4 passes through a through hole in the support plate 3. The stabilizing column 4 can enhance the stability of the lifting block 6 when it moves up and down.

[0028] Furthermore, the carbon brick clamping assembly consists of two corresponding fixing blocks 12 mounted on the upper surface of the carbon brick cutting table 1. Two corresponding clamping strips 15 are movably mounted between the two fixing blocks 12, and each clamping strip 15 is connected to the lower end of a dust shield 16. The outer side of the dust shield 16 away from the cutting disc 9 is flush with the outer side of the clamping strip 15 away from the cutting disc 9. The clamping strip 15 has a moving groove 27 that corresponds to the cutting disc 9. A guide post 13 and a bidirectional screw 14 are horizontally mounted between the two fixing blocks 12, penetrating the clamping strip 15. The two ends of the bidirectional screw 14 are threaded to the two clamping strips 15 through two sections of oppositely oriented rotating threads, and the bidirectional screw 14 is rotatably connected to the fixing blocks 12 via bearings. Rotating the bidirectional screw 14 in both directions can move the two clamping strips 15 along the guide post 13 in opposite directions, thereby clamping or releasing the carbon brick.

[0029] Furthermore, a turntable 11 is provided at the end of the bidirectional screw 14, and a handle 10 is provided at an eccentric position on the side of the turntable 11. The turntable 11 increases the rotation radius, which is more labor-saving compared to directly rotating the bidirectional screw 14, and the handle 10 makes it convenient to rotate the turntable 11.

[0030] Furthermore, the lower surface of the carbon brick cutting table 1 is provided with a dust collection box 22 that corresponds to and mates with the cutting groove 21. A movable door 23 is hinged to one end of the dust collection box 22, and a latch is provided on the movable door 23. The dust collection box 22 can collect the dust falling down from the cutting groove 21, further reducing the spread of dust. The movable door 23 can be opened from the dust collection box 22 to facilitate cleaning the dust inside the dust collection box 22.

[0031] Furthermore, a pipe support rod 18 corresponding to the connecting pipe 24 is vertically installed on the upper surface of the carbon brick cutting table 1, and the connecting pipe 24 passes through the pipe support rod 18. The pipe support rod 18 can support the connecting pipe 24.

[0032] The working principle of the special cutting device for carbon brick lining provided by this utility model is as follows: In use, place the carbon brick to be cut on the carbon brick cutting table 1, positioning it between the two clamping bars 15. The height of the clamping bars 15 should be equal to the thickness of the carbon brick. Hold the handle 10, which will drive the turntable 11 to rotate clockwise. The turntable 11 will then drive the bidirectional screw 14 to rotate. Since the bidirectional screw 14 is threadedly connected to the clamping bars 15, it will cause the two clamping bars 15 to move towards each other. The two clamping bars 15 will then cause the two dust shields 16 to move towards each other until the two clamping bars 15 clamp the carbon brick tightly, and the two dust shields 16 will also come together. Connect the connecting pipe 24 to... The system is connected to an external vacuum cleaner. When the external vacuum cleaner is activated, the PLC controller is turned on. The PLC controller controls the output shaft of motor 8 to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the cutting disc 9 to rotate. The PLC controller also controls the telescopic end of the electric telescopic rod 5 to extend downwards. The electric telescopic rod 5, via the lifting block 6 and mounting plate 7, drives the rotating shaft to move downwards. The rotating shaft then drives the cutting disc 9 downwards, gradually cutting the carbon brick until the brick is completely cut. At this point, the PLC controller stops the motor 8 and controls the electric telescopic rod 5 to stop working. The telescopic end shortens upwards, causing the cutting disc 9 to move upwards. During the cutting process, a large amount of dust is generated. Two dust shields 16 and two baffles 17 can isolate most of the dust inside, greatly reducing dust dispersion. Because there is a small gap between the cutting disc 9 and the movable grooves 25 on the baffles 17, it does not affect the suction head 26's suction inside the dust shield 16. The generated dust passes sequentially through the suction head 26, the hard dust removal pipe 20, the soft dust removal hose 19, and the connecting pipe 24 into the external suction device, thus completing dust removal. When it is necessary to remove the cut dust... When removing the carbon brick, hold the handle 10. The handle 10 drives the turntable 11 to rotate in the opposite direction. The turntable 11 drives the double-sided screw 14 to rotate in the opposite direction. The double-sided screw 14 drives the two clamping bars 15 to gradually move away from each other until the two clamping bars 15 are completely separated from the carbon brick. Then the cut carbon brick can be removed. Some dust falls into the dust collection box 22 through the cutting groove 21 for collection. When it is necessary to clean the dust inside the dust collection box 22, first open the latch of the movable door 23 to open the movable door 23, so as to facilitate the cleaning of the dust inside the dust collection box 22.
