Description

Technical Field

[0001] The invention relates to the technical field of solid waste treatment, and in particular to a solid waste crushing device. Background Art

[0002] Solid waste refers to solid, semi-solid and gaseous items and substances placed in containers that have lost their original utilization value or have not lost their utilization value but have been discarded or abandoned in production, life and other activities. In layman's terms, it is all kinds of solid garbage generated by people in their daily activities.

[0003] A solid waste crushing device is a device used to crush solid waste into smaller particles or fragments. The working process of the solid waste crushing device is that the solid waste is first fed into the crushing device through a feed port or a conveyor belt, and then the waste is subjected to mechanical forces such as extrusion, impact, shearing, etc. in the crushing device and is crushed into smaller particles or fragments. Then, the crushed material passes through a screening device to screen out particles that meet the requirements, and larger particles are returned to the crushing device for further crushing. Finally, the crushed solid waste is collected for subsequent processing or disposal.

[0004] However, considering that it is usually difficult for existing crushing devices to completely crush solid waste in one go when in use, the staff needs to use screening equipment to screen the waste after the first crushing for secondary crushing, which reduces the working efficiency of the crushing device and increases the labor of the staff. Alternatively, two sets of crushing mechanisms are set in the crushing device to crush the solid waste for a secondary crushing. However, this method will cause the small particles of waste after the first crushing to become smaller particles after the secondary crushing, so that the crushing effect of the crushing device is not uniform enough and the particle size requirement after crushing cannot be met, thereby reducing the use effect of the crushing device.

The cylindrical rod 1 42 can be installed on the rotating pull mechanism 45 in a horizontally sliding manner, and the cylindrical rod 1 42 passes through the screening frame 41. Through the cylindrical rod 1 42, the height of the other end of the screening frame 41 can change with the change of the moving frame 454, and can rotate and move along the cylindrical rod 1 42. The rotating pull mechanism 45 is used to pull the cylindrical rod 1 42 to rotate around the axis of the cylindrical rod 2 43. The pushing mechanism 44 is fixedly installed inside the box body 1. The pushing mechanism 44 is used to drive the screening frame 41 to move along the axial direction of the cylindrical rod 1 42 and the cylindrical rod 2 43. Through the pushing mechanism 44, the screening frame 41 can have a reciprocating movement effect, so that the screening frame 41 can produce a screening shaking effect, thereby improving the screening efficiency and screening effect of the screening frame 41. A guide frame 46 is fixedly installed on the inner side of the box body 1. The guide frame 46 is a frame with an inclined top. Through the guide frame 46, the solid waste that has been crushed once can slide along the guide frame 46 into the screening frame 41, thereby preventing the solid waste from falling into the gap between the screening frame 41 and the movable frame 454.

The T-plate 443 drives the collar 441 to move through the movable rod 442 which is hinged in sequence, and the collar 441 is slidably connected with the cylindrical rod 43. The moving effect of the T-plate 443 can drive the movable rod 442 to move, so that the collar 441 can slide along the axial direction of the cylindrical rod 43, so as to push the screening frame 41 to move. The fixed plate 446 is fixedly installed on the inner side of the box body 1. The T-plate 443 and the fixed plate 446 are connected by a guide column 444, and the guide column 444 is slidably connected with the fixed plate 446. The guide column 444 guides the T-plate 443 to prevent the T-plate 443 from deflecting when moving. The spring 445 is used to drive the collar 441 to move toward one end of the cylindrical rod 43. Through the elastic force of spring 445, the T-plate 443 always keeps moving upward without being affected by external force, thereby driving the ring 441 to drive the screening frame 41 to move in one direction. The circular plate 447 is fixedly installed on the rotating mechanism 6, and the rotating mechanism 6 is used to drive the circular plate 447 to rotate. The bottom of the circular plate 447 is fixedly connected with an extrusion column 448.

An inclined groove 449 is provided on the T-plate 443. When the circular plate 447 drives the extrusion column 448 to rotate, the bottom of the extrusion column 448 will contact the inclined groove 449.

During the screening process of the screening frame 41, the rotating mechanism 6 drives the movable frame 454 in the rotating pulling mechanism 45 to move, so that the screening frame 41 becomes inclined, so that the large particles of solid waste in the screening frame 41 slide into the shell 31 for secondary crushing, and the solid waste after the secondary crushing falls to the bottom of the box body 1.

[0034] The solid waste crushing device, through the screening mechanism, secondary crushing mechanism and rotating mechanism, enables the screening frame to screen the waste after primary crushing, and drives the screening frame to tilt through the moving frame, so that large particles of waste fall into the shell body for secondary crushing, making the crushing effect of the crushing device more uniform, reducing the labor of the staff and improving the working efficiency of the crushing device. At the same time, through the pushing mechanism and rotating mechanism arranged in the screening mechanism, the sleeve drives the screening frame to slide reciprocally along the cylindrical rod two and the cylindrical rod one, thereby realizing the screening shaking action and improving the screening effect and screening efficiency of the screening frame. In addition, through the protective mechanism, the staff can open or close the feeding port of the box by pressing the pedal, so that the crushing device can prevent dust floating and debris splashing in the box during the crushing process, thereby improving the safety of the staff and the air quality in the working environment.
