Description

Technical Field

[0001] The present invention relates to the technical field of rotary kilns, and particularly to a carbonization rotary kiln. Background Art

[0002] As a porous material, activated carbon is widely used in many fields such as water treatment, air purification, metal recovery, and medicine due to its large specific surface area and good adsorption performance. In the preparation process of activated carbon, carbonization activation is a key step, which directly affects the quality and performance of activated carbon.

[0003] In traditional carbonization rotary kilns, the materials are prone to adhere to the furnace shell inside the furnace, and even accumulate and block, which not only affects the carbonization effect, but also increases energy consumption and maintenance costs. In order to ensure the carbonization effect, various scraping wall mechanisms have to be added, which makes the already narrow space inside the carbonization rotary kiln even more cramped and the structure of the whole set of equipment extremely complex. For example, a carbonization rotary kiln disclosed in CN118999140B is very difficult for subsequent maintenance and has a small carbonization amount each time, and the heat has to be used to heat the whole set of scraping wall mechanisms, resulting in low efficiency.

[0004] In view of this, in order to study and improve the existing problems, a carbonization rotary kiln is provided that can reduce the complexity of the equipment and at the same time ensure that the materials are not easily adhered to the furnace shell inside the furnace. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to provide a carbonization rotary kiln that can reduce the complexity of the equipment and at the same time ensure that the materials are not easily adhered to the furnace shell inside the furnace.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: A carbonization rotary kiln, comprising a furnace body, a scraping wall mechanism and a frame; The furnace body includes a motor, a furnace liner and a furnace shell. The furnace liner is a cylindrical structure formed by flexible metal; the furnace shell is slidably and sealingly sleeved outside the furnace liner; the furnace liner includes a feeding end and a discharging end. The feeding end is rotatably connected to the frame and can be horizontally displaced, and the discharging end is rotatably connected to the frame; the motor is arranged on the frame and drives the furnace liner to rotate; there is an interlayer space between the furnace liner and the furnace shell; on the inner wall of the furnace shell, there are two guide rails arranged along the length direction with an included angle of 180°. The scraping wall mechanism includes a hydraulic push rod, a locking device and multiple groups of shaping units. The hydraulic push rod is arranged on the frame and abuts against the feeding end; the locking device is arranged on the feeding end; The shaping unit includes a rope body, a wire winder, and a pulley. The pulley is arranged on one of the guide rails, and the wire winder is arranged on the other guide rail. The rope body starts from the wire winder, passes through the pulley to form a loop around the furnace liner, and then returns to the wire winder. When scraping the wall is required, the wire winder is started to tighten the rope body so that the position where the furnace liner is tightened by the rope body is deformed into an ellipse, which facilitates the hydraulic push rod to push the feeding end and causes the furnace liner to undergo elastic deformation. When the elastic deformation reaches the preset position, the stopper locks and fixes the discharging end. At the same time, the wire winder rotates reversely to loosen the rope body, and after the hydraulic push rod is loosened, the stopper releases the discharging end, and the furnace liner uses the accumulated elastic potential energy to quickly rebound to form vibration for wall scraping.

[0007] Preferably, the shaping unit further includes a first moving block and a second moving block. The wire winder is connected to the guide rail through the first moving block, and the pulley is connected to the other guide rail through the second moving block.

[0008] Preferably, the wire winder is located on the upper track.

[0009] Preferably, each time the wire winder tightens, the angle at which the motor controls the furnace liner to stop is different from the angle at which it stopped and tightened the previous time.

[0010] Preferably, the carbonization rotary furnace further includes an air extraction pump and a one-way valve. The air extraction pump is communicated with the interlayer space through the one-way valve.

[0011] Preferably, the carbonization rotary furnace further includes a circulation pump and a heater. The furnace shell is provided with an air inlet and an air outlet, and the air outlet, the circulation pump, the heater, and the air inlet are communicated in sequence.

[0012] Preferably, the carbonization rotary furnace further includes a radiator and a three-way valve. The circulation pump is respectively communicated with the radiator and the heater through the three-way valve, and the radiator is also communicated with the air inlet.

[0013] Preferably, the furnace liner is a cylindrical structure formed of flexible breathable steel.

[0014] Preferably, the surface of the rope body is coated with a lubricating layer.

[0015] Preferably, the stopper includes a base, a spring, a bolt, and a handle; A force-bearing baffle is arranged on the feeding end; The base is located below the force-bearing baffle; a vertical groove and a horizontal groove are arranged on the base, and the horizontal groove is communicated with the vertical groove; the spring is arranged at the bottom of the vertical groove, the bolt is arranged in the vertical groove and extends out of the vertical groove to limit the force-bearing baffle; the handle passes through the horizontal groove and is connected to the bolt; The hydraulic push rod is arranged on the frame and abuts against the force-bearing baffle at the feeding end.

[0016] The beneficial effects of the present invention are as follows: By setting multiple shaping units, through the cooperation of a wire winding machine, pulleys, and a rope body, the furnace liner with a circular cross-section is constricted into an ellipse by the rope body. Due to the change in shape, the mechanical structure of the cylindrical shape changes, and it can easily undergo elastic deformation under the extrusion of a hydraulic push rod. Releasing the rope body increases the energy of the elastic deformation. Releasing through the locking device allows the accumulated energy to be instantaneously released to form a rebound vibration. The vibration generated by the rebound causes the materials adhering to the inner wall of the furnace liner to fall off under the action of the vibration and rebound, that is, "wall scraping" is achieved through vibration; By externalizing the wall scraping mechanism, the space inside the furnace liner can be larger, more materials can be accommodated at one time, and there is no need for a complex maintenance process, improving efficiency; Moreover, through the rotation of the furnace liner driven by the rope body and the motor, the angle of constricting the furnace liner during each wall scraping can be adjusted, avoiding mechanical fatigue caused by a fixed deformation angle at a fixed position and ensuring the service life of the furnace liner.

[0018] To describe in detail the technical content, achieved objectives, and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0019] Please refer to Figures 1 to 3 , a carbonization rotary furnace, comprising a furnace body 1, a wall scraping mechanism 2, and a frame 3; The furnace body 1 includes a motor, a furnace liner 11, and a furnace shell 12. The furnace liner 11 is a cylindrical structure formed by flexible metal. The furnace shell 12 is slidably and sealingly sleeved outside the furnace liner 11. The furnace liner 11 includes a feeding end 111 and a discharging end 112. The feeding end 111 is rotatably connected to the frame 3 and can be horizontally displaced. The discharging end 112 is rotatably connected to the frame 3. The motor is arranged on the frame 3 and drives the furnace liner 11 to rotate. There is an interlayer space 13 between the furnace liner 11 and the furnace shell 12. On the inner wall of the furnace shell 12, there are two guide rails arranged along the length direction with an included angle of 180°. The scraping mechanism 2 includes a hydraulic push rod 21, a lock 22, and multiple groups of shaping units 23. The hydraulic push rod 21 is arranged on the frame 3 and abuts against the feeding end 111. The lock 22 is arranged on the feeding end 111. The shaping unit 23 includes a rope body 231, a wire winding machine 232, and a pulley 233. The pulley 233 is arranged on one of the guide rails, and the wire winding machine 232 is arranged on the other guide rail. The rope body 231 starts from the wire winding machine 232, passes through the pulley 233 to form a loop around the furnace liner 11, and then returns to the wire winding machine 232. When scraping the wall is required, start the wire winding machine 232 to tighten the rope body 231 so that the furnace liner 11 is tightened by the rope body 231 and deformed into an oval shape, which facilitates the hydraulic push rod 21 to push the feeding end 111 and causes the furnace liner 11 to undergo elastic deformation. When the elastic deformation reaches the preset position, the lock 22 locks and fixes the discharging end 112. At the same time, the wire winding machine 232 rotates in the reverse direction to loosen the rope body 231, and after the hydraulic push rod 21 is loosened, the lock 22 releases the discharging end 112, and the furnace liner 11 uses the accumulated elastic potential energy to quickly rebound to form vibration for scraping the wall.

[0020] As can be seen from the above description, by setting multiple groups of shaping units 23, through the cooperation of the wire winding machine 232, the pulley 233, and the rope body 231, the furnace liner 11 with a circular cross-section is tightened by the rope body 231 into an oval shape. Due to the change in shape, the mechanical structure of the cylindrical shape changes, and it can easily undergo elastic deformation under the extrusion of the hydraulic push rod 21. Loosening the rope body 231 increases the energy of the elastic deformation. Releasing through the lock 22 causes the accumulated energy to be instantaneously released to form a rebound vibration. The vibration generated by the rebound causes the materials adhering to the inner wall of the furnace liner 11 to fall off under the action of the vibration and rebound. By placing the scraping mechanism 2 outside, the space inside the furnace liner 11 can be larger, more materials can be accommodated at one time, and there is no need for a complex maintenance process, improving efficiency. Moreover, through the rotation of the rope body 231 and the motor driving the furnace liner 11, the angle at which the furnace liner 11 is tightened during each scraping can be adjusted, avoiding mechanical fatigue caused by a fixed deformation angle at a fixed position and ensuring the service life of the furnace liner 11.

[0021] Further, the shaping unit 23 further includes a first moving block and a second moving block. The winding machine 232 is connected to the guide rail through the first moving block, and the pulley 233 is connected to another guide rail through the second moving block.

[0022] As can be seen from the above description, through the settings of the first moving block and the second moving block, the positions of the winding machine 232 and the pulley 233 can be adjusted, avoiding mechanical fatigue caused by always tightening in the same place and extending the service life.

[0023] Further, the winding machine 232 is located on the upper track.

[0024] As can be seen from the above description, by having the winding machine 232 above, it can avoid damage to the winding machine 232 caused by dust leaking into the sandwich space 13.

[0025] Further, each time the winding machine 232 tightens, the angle at which the motor controls the furnace liner 11 to stop is different from the angle at which it stopped and tightened the previous time.

[0026] As can be seen from the above description, by having different tightening angles each time, for example, the first time is 0°, the second time is 1°, the third time is 2°, and so on, until the 360th time, it returns to 0°; it can also be the first time is 0°, the second time is 220°, the third time is 156°, and random is also okay, as long as it doesn't repeat before and after; this way, it avoids repeated deformation in one place.

[0027] Further, the carbonization rotary furnace further includes an air extraction pump and a one-way valve. The air extraction pump is connected to the sandwich space 13 through the one-way valve.

[0028] As can be seen from the above description, through the settings of the air extraction pump and the one-way valve, it can achieve vacuum pumping and reduce heat loss during processing.

[0029] Further, the carbonization rotary furnace further includes a circulation pump and a heater. The furnace shell 12 is provided with an air inlet and an air outlet, and the air outlet, the circulation pump, the heater, and the air inlet are connected in sequence.

[0030] As can be seen from the above description, through the settings of the circulation pump and the heater, it can facilitate preheating of the furnace liner 11 or achieve rapid temperature rise.

[0031] Further, the carbonization rotary furnace further includes a radiator and a three-way valve. The circulation pump is connected to the radiator and the heater respectively through the three-way valve, and the radiator is also connected to the air inlet.

[0032] As can be seen from the above description, through the setting of the radiator, it can facilitate temperature adjustment.

[0033] Further, the furnace liner 11 is a cylindrical structure formed by flexible breathable steel.

[0034] As can be seen from the above description, by using the breathable steel, the hot air can fill the interlayer space 13 and penetrate into the furnace liner 11, and the gas can blow off the materials adhering to the inner wall of the furnace liner 11 or form an air film to make it difficult for the materials to adhere. Combining with the scraping mechanism 2 can improve the effect of avoiding adhesion.

[0035] Furthermore, a lubricating layer is coated on the surface of the rope body 231.

[0036] As can be seen from the above description, through the setting of the lubricating layer, the friction between the furnace liner 11 and the rope body 231 can be reduced, and the fracture caused by excessive friction can be avoided.

[0037] Furthermore, the stopper 22 includes a base 221, a spring, a bolt 222 and a handle 223; A stress baffle 113 is arranged on the feeding end 111; The base 221 is located below the stress baffle 113; a vertical groove and a horizontal groove are arranged on the base 221, and the horizontal groove is communicated with the vertical groove; the spring is arranged at the bottom of the vertical groove, the bolt 222 is arranged in the vertical groove and extends out of the vertical groove to limit the stress baffle 113; the handle 223 passes through the horizontal groove and is connected to the bolt 222; The hydraulic push rod 21 is arranged on the frame 3 and abuts against the stress baffle 113 of the feeding end 111.
