Description

Technical Field

[0001] The invention relates to the technical field of lithium slag granulating devices, in particular to a double-roller machine for solid waste resource utilization. Background Art

[0002] The double roller mill for recycling solid waste is a granulating device specially used for industrial waste, waste materials or other materials to be processed. The materials are squeezed and sheared by the relative rotation of the double rollers to make them harmless or convenient for subsequent processing. Its main structure includes a frame, a drive device, two relatively rotating rollers and an adjustment device. The equipment features include high-efficiency granulation capacity, adjustable granulation particle size, stable operation and simple maintenance. It is widely used in solid waste treatment, construction waste treatment and ore processing.

[0003] When the double-roll mill processes materials with high humidity, it is easy to form an adhesion layer on the roller surface and in the gap, which hinders the continuous flow of materials and causes poor operation of the equipment. Materials with high humidity contain more water, which enhances the adhesion between material particles through surface tension and reduces the friction between particles. This "wetting effect" (the wetting effect caused by water makes it easier for materials to slip and accumulate between rollers) makes it easier for materials to slip and accumulate between rollers, making it difficult to granulate. In the process of the double-roll mill squeezing and shearing wet materials, water tends to penetrate into the gap between the rollers and fill the effective space in the granulation area. As the gap is gradually blocked by wet materials, the granulation efficiency decreases, which eventually leads to equipment blockage, increasing maintenance costs and downtime losses, and affecting the stability of production plans.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a solid waste resource utilization double roller machine, which has the following

[0018] Beneficial effects:

[0019] 1. The solid waste resource utilization double roller machine uses a reverse mechanism. When the granulating roller is blocked by the material, the granulating roller reverses to release the blocked material again. At this time, the resistance of the granulating roller is reduced, and the trapezoidal block continues to enter the transmission groove after rotating one circle, so that the granulating roller rotates forward again. Repeated forward and reverse rotation, the granulating roller releases the blocked material when reversing, and then continues to granulate by forward rotation to prevent equipment shutdown or damage due to blockage. This forward and reverse cycle can handle the blockage problem without manual intervention, greatly improving the automation level of the equipment. Blockage will interrupt the continuous operation of the production line, and this design can quickly clear the blocked material through automatic forward and reverse rotation, so that the granulation operation can be continued, avoiding long-term stagnation of the production line. For highly viscous, easy to accumulate or irregularly shaped materials, the granulation process is prone to blockage. The forward and reverse cycle can continuously adjust the position of the material so that it can be granulated step by step, improving the processing efficiency. When blocked, the granulating roller is subjected to greater resistance, which may cause overload or even damage. By releasing the resistance through timely reversal, not only the granulating roller itself is protected, but also the load on the transmission mechanism and motor is reduced, extending the overall life of the equipment. Traditional equipment requires manual cleaning when blocked, which increases maintenance time and labor costs. This automatic forward and reverse function can significantly reduce manual intervention and improve equipment utilization. Through dynamic adjustment of forward and reverse rotation, it can ensure that the material completes the granulation process in the best position. Repeated forward and reverse operations further improve the uniformity and efficiency of material granulation. The forward and reverse cycle design is a defensive strategy that can deal with unexpected material abnormalities, such as oversized pieces of material or foreign matter entering the granulation area, to prevent equipment failure due to overload operation.

[0020] 2. The solid waste resource utilization roller machine uses a knocking mechanism to break the adhesion and friction between the blocked materials through mechanical vibration and impact force, helping the materials to disperse and loosen again. Materials with high humidity or high viscosity are prone to form tight bonds or accumulation, resulting in decreased fluidity. Through the action of the knocking mechanism, the loosened materials can flow back into the granulation rollers to restore the normal working state of the equipment. This automatic knocking process reduces the equipment downtime caused by blockage and reduces the need for manual cleaning, especially in unmanned or remote operation environments. It can significantly improve the working efficiency of the equipment. By knocking to remove the blockage, the equipment downtime caused by material adhesion or accumulation can be minimized, thereby improving the efficiency of the overall production line.

[0021] 3. The solid waste resource utilization double roller machine uses the granulation mechanism to mechanically cut off the power transmission to prevent the drive motor from continuing to forcefully drive the granulation roller, thereby avoiding motor overload, component wear or equipment damage, and can prevent the granulation roller from continuing to operate in a blocked state, preventing the material from piling up more tightly and aggravating the blockage problem. Stopping the drive in time can protect the granulation roller, main shaft and related components from excessive mechanical stress, thereby extending the service life of the equipment, reducing the frequency of maintenance and replacement of parts, and reducing operating costs. When the material is blocked, the automatic shutdown mechanism of the drive motor allows the equipment to wait in a safe state for manual or automatic clearing of the blockage, avoiding equipment performance degradation or malfunction due to continuous blockage.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 11A solid waste resource utilization double roller machine includes a machine body 1, which is used to support and fix the entire equipment structure, provide a stable operating basis, and is the basic structure of the granulating device double roller machine, and carries the installation and operation of various functional components; a feed port 2, which is arranged on the top of the machine body 1, and is used to introduce the material to be processed into the equipment to ensure that the material evenly enters the granulating mechanism 3 for subsequent processing; a granulating mechanism 3, which is used to granulate the incoming material, and mainly realizes the refinement and granulation of the material through the action of the granulating roller 33 and other matching parts. The mechanism applies pressure and shear force to effectively granulate the material into the required particle size between the rollers. When blockage occurs, the granulating mechanism 3 stops the driving device of the granulating roller 33 to prevent further blockage or equipment damage, thereby improving the safety and stability of the equipment; the knocking mechanism 4 is used to knock the granulating mechanism 3 when blockage occurs. The knocking mechanism 4 destroys the adhesion or friction between the materials by applying a rapid impact force. When the materials are piled up, especially the materials with high humidity or high viscosity, the particles are easy to form a close bond or pile up. The impact force generated by knocking will quickly break these bonds, reduce the friction between the particles, loosen the material again, and restore fluidity; the reversing mechanism 5, the reversing mechanism 5 is used to reverse the granulating roller 33 when a blockage occurs, to help clean and dredge the blockage, and its principle is to change the rotation direction of the granulating roller 33, and the reverse rotation can make the material flow in the opposite direction or be loosened again, thereby breaking the state of material accumulation. When reversing, the relative movement direction of the granulating roller 33 and the material changes, which helps to remove the blockage caused by the viscosity of the material or excessive humidity. The reverse rotation can destroy the adhesion between the materials, loosen them, and reduce the pressure in the blocked area, thereby improving the fluidity of the material and the operating efficiency of the equipment. The design of the reversing mechanism 5 helps to protect the equipment and avoid mechanical damage or performance degradation caused by prolonged blockage.

[0036] The granulating mechanism 3 includes a driving motor 31, which is fixedly connected to the outer wall of the machine body 1. The output shaft of the driving motor 31 is fixedly connected to the main shaft 32. The outer wall of the main shaft 32 is rotatably connected to a granulating roller 33. The inner wall of the granulating roller 33 is rotatably connected to a driven shaft 34. The inner wall of the main shaft 32 is fixedly connected to one end of a spring 35. The other end of the spring 35 is fixedly connected to a trapezoidal block 36. The bottom of the trapezoidal block 36 is fixedly connected to a guide rod 37. A transmission groove 38 is provided on the inner wall of the granulating roller 33. When the trapezoidal block 36 is located in the transmission groove 38, the inclined surface of the rotating trapezoidal block 36 passes through the transmission groove 38. The granulating roller 33 is driven to rotate through the transmission groove 38. When the granulating roller 33 is blocked and cannot rotate, the transmission groove 38 contacts the inclined surface of the trapezoidal block 36, so that the trapezoidal block 36 is retracted into the main shaft 32. Two granulating rollers 33 are provided. The two granulating rollers 33 are symmetrically arranged and cooperate with each other to jointly complete the granulation of the material. The symmetrical arrangement design can ensure that the granulating rollers 33 are evenly stressed, thereby improving the stability and working efficiency of the equipment. The two granulating rollers 33 rotate relative to each other with a certain gap. When the material enters the gap between the granulating rollers 33, the material is granulated into the required particle size through the shearing and compression of the granulating rollers 33. The symmetrical arrangement can also reduce the vibration of the equipment caused by uneven force, extend the service life of the granulating roller 33, and improve the working stability of the overall equipment. The outer wall of the driven shaft 34 is rotatably connected to the body 1. The main shaft 32 and the driven shaft 34 are symmetrically arranged on both sides of the granulating roller 33, ensuring that the granulating roller 33 is supported evenly during the rotation process. This symmetrical arrangement design can effectively balance the load on both sides of the granulating roller 33, avoiding vibration, offset or uneven wear caused by asymmetric force. Specifically, the main shaft 32 is responsible for driving the granulating roller 33 to rotate, while the driven shaft 34 is responsible for bearing the load. It plays a supporting and stabilizing role. It forms a symmetrical supporting structure together with the main shaft 32. Through this design, the granulating roller 33 can maintain stable rotation during operation, while avoiding unnecessary mechanical stress caused by uneven force, extending the service life of the equipment and improving work efficiency. Therefore, the driven shaft 34 serves as a symmetrical supporting component to ensure the stability and uniform force of the granulating roller 33, thereby ensuring the smooth operation of the equipment under high load. The trapezoidal block 36 is slidably connected to the inner wall of the main shaft 32. The trapezoidal block 36 serves as a sliding element and can slide on the inner wall of the main shaft 32 in a certain direction.

[0037] The knocking mechanism 4 includes a spring 2 41, one end of which is fixedly connected to the inner wall of the main shaft 32, the other end of which is fixedly connected to an inclined plate 42, the outer wall of the inclined plate 42 is fixedly connected to a long condition 43, the outer wall of the long condition 43 is fixedly connected to one end of a spring 3 44, the other end of the spring 3 44 is fixedly connected to a circular ring set 45, the outer wall of the circular ring set 45 is fixedly connected to a connecting plate 46, the outer wall of the connecting plate 46 is hinged with a rotating plate 47, and the outer wall of the rotating plate 47 is fixedly connected to one end of an elastic sheet 48 The other end of the elastic sheet 48 is fixedly connected to the connecting plate 46. The function of the elastic sheet 48 is to maintain the relative vertical position between the rotating plate 47 and the connecting plate 46. A fixed limiting plate 49 is fixedly connected to the inner wall of the granulating roller 33. The outer wall of the long condition 43 is slidably connected to the inner wall of the main shaft 32, so that the long condition 43 can slide on the inner wall of the main shaft 32 in a certain direction. The inner wall of the annular sleeve 45 is slidably connected to the outer wall of the long condition 43. A plurality of fixed limiting plates 49 are provided, and the fixed limiting plates 49 are arranged in a circular array.

[0038] The reverse mechanism 5 includes a spring four 51, one end of which is fixedly connected to the outer wall of the long condition 43, and the other end of the spring four 51 is fixedly connected to a transmission member 52. The outer wall of the driven shaft 34 is fixedly connected to a driving limit plate 53, and the outer wall of the driven shaft 34 is fixedly connected to a first transmission gear 54. The outer wall of the body 1 is rotatably connected to a second transmission gear 55, and the outer wall of the second transmission gear 55 is fixedly connected to a reduction pinion 56. The outer wall of the granulating roller 33 is fixedly connected to a gear ring 57. A plurality of driving limit plates 53 are provided, and the driving limit plates 53 are arranged in a circular array. The second transmission gear 55 meshes with the first transmission gear 54, and the gear ring 57 meshes with the reduction pinion 56.

[0039] In summary, when the solid waste resource utilization double-roller machine performs harmless treatment on materials with high humidity, the drive motor 31 is turned on to drive the main shaft 32 to rotate, and the main shaft 32 drives the trapezoidal block 36 to rotate. The inclined surface of the trapezoidal block 36 conflicts with the transmission groove 38. Under the action of the spring 35, the trapezoidal block 36 drives the transmission groove 38 and the granulating roller 33 to rotate to granulate the material.

[0040] When the material blocks the granulating roller 33 and makes it unable to continue to rotate, the reaction force on the transmission groove 38 in the granulating roller 33 increases, so that the mutual resistance between the transmission groove 38 and the inclined surface of the trapezoidal block 36 increases. At this time, the trapezoidal block 36 is squeezed into the main shaft 32, so that the driving motor 31 no longer drives the granulating roller 33. When the material blocks the granulating roller 33, the resistance between the transmission groove 38 and the inclined surface of the trapezoidal block 36 increases, and the trapezoidal block 36 is forced to retract into the main shaft 32. This design mechanically cuts off power transmission to prevent the drive motor 31 from continuing to forcefully drive the granulating roller 33, thereby avoiding motor overload, component wear or equipment damage, and can prevent the granulating roller 33 from continuing to operate in a blocked state, preventing materials from piling up more densely and aggravating the blockage problem. Stopping the drive in time can protect the granulating roller 33, the main shaft 32 and related components from excessive mechanical stress, thereby extending the service life of the equipment, reducing the frequency of maintenance and replacement of parts, and reducing operating costs. When the material is blocked, the automatic shutdown mechanism of the drive motor 31 allows the equipment to wait in a safe state for manual or automatic clearing of the blockage, thereby avoiding equipment performance degradation or malfunction due to continuous blockage.

[0041] At this time, the driving motor 31 continues to drive the main shaft 32 to rotate, and the trapezoidal block 36 drives the guide rod 37 to move in the direction of the inclined plate 42, so that the guide rod 37 contacts the inclined surface of the inclined plate 42, so that the inclined plate 42 moves in the direction of the spring 2 41, so that the inclined plate 42 drives the long condition 43, the spring 3 44, the annular set 45, the connecting plate 46, the rotating plate 47, and the elastic sheet 48 to move in the direction of the spring 2 41. At this time, the main shaft 32 drives the connecting plate 46 and the rotating plate 47 to rotate, and the rotating plate 47 moves to the fixed limit The position of the positioning plate 49 causes the fixed limiting plate 49 to be struck by the rotating plate 47, and under the action of the elastic sheet 48, the rotating plate 47 will continue to return to its position and remain vertical with the connecting plate 46 after the striking, and then strike the fixed limiting plate 49 again, so that the rotating plate 47 repeatedly strikes the fixed limiting plate 49. Through mechanical vibration and impact force, the adhesion and friction between the blocked materials can be destroyed, and the materials can be re-dispersed and loosened. Materials with high humidity or high viscosity are prone to form a tight bond or accumulation, resulting in decreased fluidity. Through the action of the knocking mechanism 4, the loosened materials can flow back into the granulating rollers 33 to restore the normal working state of the equipment. This automatic knocking process reduces the equipment downtime caused by blockage and reduces the need for manual cleaning. Especially in an unmanned or remote operation environment, it can significantly improve the working efficiency of the equipment. By knocking to remove the blockage, the equipment downtime caused by material adhesion or accumulation can be minimized, thereby improving the efficiency of the overall production line.

[0042] At this time, the long condition 43 drives the spring four 51 and the transmission member 52 to move in the direction of the driving limit plate 53. At this time, the main shaft 32 drives the long condition 43 to rotate, the long condition 43 drives the transmission member 52 to rotate, the transmission member 52 resists and drives the driving limit plate 53 to rotate, the driving limit plate 53 drives the driven shaft 34 to rotate, the driven shaft 34 drives the first transmission gear 54 to rotate forward, the first transmission gear 54 drives the second transmission gear 55 to reverse, the second transmission gear 55 drives the reduction pinion 56 to reverse, the reduction pinion 56 drives the gear ring 57 to reverse, the gear ring 57 drives the granulating roller 33 to reverse, at this time, the granulating roller 33 reverses and releases the blocked material again, at this time the resistance of the granulating roller 33 The trapezoidal block 36 rotates one circle and then continues to enter the transmission groove 38, so that the granulating roller 33 rotates forward again, and rotates forward and backward repeatedly. The granulating roller 33 releases the blocked material when reversing, and then continues to granulate by forward rotation to prevent the equipment from stopping or being damaged due to blockage. This forward and reverse cycle can handle the blockage problem without manual intervention, which greatly improves the automation level of the equipment. Blockage will interrupt the continuous operation of the production line, and this design can quickly clean up the blocked material through automatic forward and reverse rotation, so that the granulation operation can be continued, avoiding the long-term stagnation of the production line. For materials with high viscosity, easy accumulation or irregular shape, the granulation process is prone to blockage. The forward and reverse cycle can continuously adjust the position of the material so that it can be granulated step by step, improving the processing efficiency. When blocked, the granulating roller 33 bears a large resistance, which may cause overload or even damage. By releasing the resistance in time, not only the granulating roller 33 itself is protected, but also the load of the transmission mechanism and the motor is reduced, and the overall life of the equipment is extended. Traditional equipment needs to be manually cleaned when blocked, which increases maintenance time and labor costs. This automatic forward and reverse function can significantly reduce manual intervention and improve equipment utilization. Through dynamic adjustment of forward and reverse rotation, it can ensure that the material completes the granulation process at the best position. Repeated forward and reverse operations further improve the uniformity and efficiency of material granulation. The forward and reverse cycle design is a defensive strategy that can deal with unexpected material abnormalities, such as oversized pieces of material or foreign matter entering the granulation area, to prevent equipment failure due to overload operation.
