Description

Technical Field

[0002] Solid waste (solid waste) refers to solid and semi-solid waste substances generated by humans in production, consumption, life and other activities. Generally speaking, it is "garbage". In the process of solid waste treatment, a compression and packing device for solid waste treatment is usually required to compress and pack solid waste for easy transportation. However, the existing compression and packing devices for solid waste treatment have a single structure and a single function. They cannot crush garbage, and there is a large gap between solid wastes. As a result, the compression and packing device can only compress a small amount of solid waste at a time, leading to low processing efficiency. In addition, the existing compression and packing devices cannot flexibly adjust the single feeding amount according to needs and cannot meet the use requirements.

[0013] Beneficial effects: Compared with the prior art, the utility model provides a compression and packaging device that can be used for solid waste. The compression and packaging device that can be used for solid waste treatment has a unique structure and is easy to use. Solid waste enters the treatment barrel through the feed port, and the driving motor drives the driving shaft to rotate. The rotating blade on the driving shaft cooperates with the fixed blade to crush the solid waste. The crushed solid waste particles remain at the bottom of the treatment barrel, waiting for further processing; the rotating shaft is driven by the meshing of the half gear and the driving gear to make the rotating shaft rotate intermittently, and the rotating shaft drives the connecting barrel to rotate intermittently through the belt drive, and each time it rotates 180 degrees, the rotation of the connecting barrel drives the turntable and the first storage pipe to rotate synchronously, thereby realizing intermittent transportation of solid waste particles.

[0014] As a lifting mechanism, the electric telescopic rod controls the lifting of the sleeve to adjust the overlapping part size between the first storage pipe and the second storage pipe, thereby controlling the single - time feeding amount. When the connecting ball moves into the trapezoidal notch, the sealing plate opens, allowing solid waste particles to enter the extrusion mechanism; the solid waste particles enter the extrusion box through the feed hopper. The motor drives the screw barrel to rotate through belt transmission, so that the screw rod pushes the extrusion plate to move to the right. The movement of the extrusion plate compresses the solid waste particles. At the same time, a negative pressure is generated in the first air cylinder, and the air cylinder contracts through the connecting pipe, driving the baffle plate to move to the left to block the discharge port. When the solid waste is extruded into blocks, the motor rotates in the reverse direction, separating the extrusion plate and the baffle plate, and the compressed block is discharged from the discharge port.

[0015] Through the coordinated setting of the crushing component, intermittent feeding mechanism, lifting mechanism and extrusion mechanism, on the one hand, the entire treatment process is automatically controlled by the controller, reducing manual intervention and improving work efficiency and safety. On the other hand, not only can the solid waste particles enter the extrusion mechanism orderly and quantitatively, avoiding the blockage or overload problems that may be caused by continuous feeding, but also the extrusion mechanism can compress more solid waste at a single time, improving the compression efficiency. In addition, the design of the lifting mechanism allows adjusting the single - time feeding amount according to actual needs, improving the flexibility and adaptability of the equipment.

[0029] The extrusion assembly includes a first air cylinder 30 and an extrusion plate 31. The first air cylinder 30 is fixedly installed on the left side wall of the extrusion box 28. The extrusion plate 31 is installed in the extrusion box 28 between the feed hopper 29 and the first air cylinder 30 along a transverse sliding manner. A piston 33 is mounted in the first air cylinder 30 along a transverse sliding manner. A screw 32 is rotatably installed on the right side of the piston 33. The other end of the screw 32 extends out of the first air cylinder 30 and is rotatably connected to the extrusion plate 31. A screw barrel 34 is threadedly mounted on the screw 32 between the first air cylinder 30 and the extrusion plate 31, and the screw barrel 34 is transmission-connected to the drive assembly.

[0030] The driving assembly includes a transmission belt 36 and an electric motor 37 fixedly mounted on the extrusion box 28, a fourth pulley 38 is fixedly mounted on the output shaft of the electric motor 37, fixed rings are rotatably mounted on the outside of both ends of the screw barrel 34, the two fixed rings are fixedly connected to the extrusion box 28, a third pulley 35 is fixedly mounted on the screw barrel 34 between the two fixed rings, the third pulley 35 and the fourth pulley 38 are connected by a transmission belt 36, connecting pipes are fixedly mounted on the front and rear sides of the left end of the first air cylinder 30, the other ends of the two connecting pipes are respectively connected to the input ends of the adjacent side cylinders 17, in the initial state, the output end of the cylinder 17 is in an extended state, and there are various ways to install the fixing rings, for example: support rods are fixedly mounted on the outer ring surfaces of the two fixing rings, and the other ends of the support rods are fixedly connected to the extrusion box 28.

[0031] When the staff uses this device to process solid waste, first, the solid waste is poured into the processing cylinder 1 through the feeding port and crushed by the crushing component in the processing cylinder 1. The crushed particles will remain at the bottom of the processing cylinder 1. Since in the initial state, the discharge pipe corresponds to one of the first storage pipes 19, and while the crushing component is crushing, it will drive the lever 8 and the rotating shaft 9 to rotate. The lever 8 can dial the crushed solid waste into the discharge pipe. The rotating shaft 9 drives the rotating shaft 11 to rotate intermittently through the meshing transmission of the half gear 10 and the driving gear 12, and drives the connecting cylinder 16 to rotate intermittently through belt transmission. Moreover, each time the connecting cylinder 16 rotates, it can only rotate 180 degrees. In addition, since the first storage pipe 19 is inserted into the second storage pipe 20, the connecting cylinder 16 will drive the turntable 18 to rotate synchronously when rotating, so that the turntable 18 and the limit ring 24 rotate relatively.

[0032] When the first storage pipe 19 below the discharge pipe moves above the input end of the extrusion mechanism, the corresponding connecting ball 22 will move into the trapezoidal notch and stay for a period of time. During this period, the sealing plate 21 opens, and the crushed particles flow into the extrusion box 28 through the feed hopper 29; then, the connecting cylinder 16 rotates again. When the corresponding connecting ball 22 moves to the end of the notch, the sensor transmits a signal to the controller 2, and the controller 2 controls the motor 37 to act, and drives the screw cylinder 34 to rotate through belt transmission, so that the screw 32 moves horizontally, and then pushes the extrusion plate 31 to move to the right. While the extrusion plate 31 moves to the right, the first air cylinder 30 on the left side of the piston 33 is in a negative pressure state. Since the left side of the first air cylinder 30 is connected to the input end of the air cylinder 17, the output end of the air cylinder 17 contracts, and drives the baffle plate 39 to move to the left to block the discharge port.

[0033] Moreover, since the length of the baffle plate 39 is greater than the length of the discharge port, when the baffle plate 39 blocks the discharge port, the extrusion plate 31 and the baffle plate 39 continue to approach each other until the extrusion plate 31 extrudes the solid waste particles into blocks. Then, the controller 2 controls the output shaft of the motor 37 to rotate in the reverse direction, so that the extrusion plate 31 and the baffle plate 39 move away from each other. When the baffle plate 39 separates from the discharge port, the compressed block drops from the discharge port. In the actual application process, the reverse rotation of the output shaft of the motor 37 can be achieved in various ways. For example: by controlling the number of rotation circles of the output shaft of the motor 37 through the encoder built in the motor 37, so as to control the horizontal movement distance of the extrusion plate 31. When the extrusion plate 31 moves a certain distance, it automatically moves in the reverse direction.

[0034] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that a vibration motor is fixedly installed on the extrusion box 28, and the vibration motor is used to facilitate the discharge of the compressed solid waste from the discharge port and prevent the compressed block from getting stuck in the extrusion box 28.
