Horizontal hammer breaking device for disassembling waste refrigerator

Abstract

This utility model relates to a horizontal hammer crusher for dismantling waste refrigerators, comprising a frame unit, a rotating shaft unit, several first hammer crushing units, several second hammer crushing units, a drive unit, a screen unit, a feeding unit, and a discharging unit. Its advantages lie in that the drive unit drives the rotating shaft unit to rotate within the hammer crushing chamber, thereby causing the first and second hammer crushing units to alternately crush the mixture within the chamber. The crushed material is then screened and collided with by the screen unit; material conforming to the screen unit size enters the discharging unit for output, resulting in uniform particle size. Material rebounding from collisions is further crushed. This method effectively crushes not only metals and foam materials, achieving high crushing efficiency, but also reduces the risk of screen unit clogging and the number of impacts from the first and second hammer crushing units, thus reducing wear on these units. Furthermore, the structure is reasonable and compact, facilitating installation and maintenance, and resulting in high production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of hammer crusher technology, and in particular to a horizontal hammer crusher device for dismantling waste refrigerators. Background Technology

[0002] Traditional refrigerator dismantling methods mainly include manual and mechanical dismantling. While manual dismantling can achieve relatively precise sorting, it is inefficient, labor-intensive, and poses safety hazards, making it difficult to meet the growing demand for waste refrigerator disposal. Mechanical dismantling primarily relies on crushing equipment, such as shredders and hammer crushers.

[0003] Currently, the common processing method is to first use a shredder to preliminarily shred the waste refrigerator, breaking it down into smaller pieces. Then, the shredded pieces are sent to a hammer crusher for secondary crushing to further reduce the particle size, making it easier for subsequent sorting and recycling.

[0004] Because refrigerators contain various materials such as metal outer shells, plastic inner liners, polyurethane foam, glass, wires, and compressors, the shredded materials are mixed together after shredding. These materials have vastly different physical properties; for example, the metal outer shell is hard, the plastic inner liner is relatively tough, and the polyurethane foam is lightweight and brittle, and may even produce some harmful gases, posing a challenge to subsequent hammer crushing. Ordinary hammer crushers often only have a hammer crushing function and use a uniform design, making it difficult to efficiently handle such diverse and structurally different materials. They often face low crushing efficiency, especially for tough plastics and lightweight foams, which are prone to incomplete crushing. Furthermore, the mixture of various materials, especially foam, can easily clog the equipment, affecting its normal operation. The significant differences in hardness between the different materials can also cause uneven wear on the hammers, shortening the equipment's lifespan and increasing maintenance costs.

[0005] Regarding the existing hammer crushers, there are still no effective solutions to problems such as low efficiency in processing waste refrigerators, easy clogging of equipment, and uneven wear of hammers. Utility Model Content

[0237] The drive element 143 is activated, and the reduction element 144 adjusts the speed, driving the first rotating shaft element 111 to rotate. The first rotating shaft element 111 drives the hammer disc element 112, several first hammer crushing elements 122, and several second hammer crushing elements 132 to rotate. The pre-treated material enters the hammer crushing chamber formed by the upper shell element 103 and the lower shell element 101 from the second feeding element 161 through the first feeding element 104. The several first hammer crushing elements 122 and several second hammer crushing elements 132 alternately crush the material. 22 is mainly used for hammer crushing hard materials (such as metal) and for preliminary hammer crushing of light materials (such as foam); several second hammer crushing elements 132 can effectively crush light materials and for preliminary hammer crushing of hard materials; the splashed material collides with the first rebound element 152 to further crush the material, and the rebounded material re-enters the hammer crushing chamber for hammer crushing. After hammer crushing, the material smaller than the size of the screen element 151 is screened out by the screen element 151 and enters the receiving element 171, and is then output by the second discharge element 172.

[0238] When the equipment needs to be repaired, the connection between the lower housing component 101 and the upper housing component 103 can be opened, and the upper housing component 103 can be removed using the suspension component 106, so that the equipment can be repaired.

[0239] The technical effects of this utility model are as follows:

[0240] The drive unit rotates the shaft unit within the hammer crushing chamber, which in turn drives the first and second hammer crushing units to alternately crush the mixture within the chamber. The crushed material is then screened and impacted by a screen unit. Material that meets the screen unit's dimensions enters the discharge unit for output, resulting in uniform particle size. Material rebounding from impacts is further crushed. This method effectively crushes not only metals and foam materials, but also reduces the risk of screen unit clogging and the number of impacts from the first and second hammer crushing units, thereby reducing wear on these units and eliminating the risk of equipment blockage and uneven hammer wear. The structure is reasonable and compact, easy to install and maintain, and has high production efficiency, solving the problem of low efficiency in processing waste refrigerators with existing hammer crushers.
