Description

Technical Field

[0001] The utility model relates to the technical field of urban environmental protection, in particular to high-efficiency solid waste compression equipment. Background Art

[0002] The Chinese patent application number: CN202321530846.7 proposes a solid waste compression processing device. After the solid waste is compressed, the compression mechanism of the device will reversely drive the pushing mechanism to push the compressed garbage to the right, and at the same time, the box door on the second opening is opened through the linkage mechanism, so that the compressed garbage is discharged from the second opening, thereby improving the utilization rate of the storage space in the garbage array. However, the device still has the following defects:

[0003] The compression efficiency is low, and the pre-treatment capacity for solid waste is limited. In daily life, some solid wastes are large in size and complex in shape. Direct compression may not be effective and requires pre-crushing, otherwise the equipment will be damaged. In addition, domestic solid waste is often mixed with waste liquid, which requires pre-solid-liquid separation. Otherwise, it will cause foul odor and harmful gases to be generated inside the solid waste, polluting the environment.

[0004] Therefore, in order to solve the defect that the compression device has limited pre-treatment capacity for solid waste and leads to poor compression effect, it is necessary to propose a high-efficiency solid waste compression equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a high-efficiency solid waste compression equipment, which crushes solid waste with large volume and complex shape through a crushing roller, and separates the waste liquid mixed in the solid waste through a screen, thereby improving the pretreatment capacity of the solid waste and enhancing the compression effect, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A high-efficiency solid waste compression device comprises a crushing box and a compression box, wherein a crushing roller is movably installed at the upper end of the crushing box, one end of the crushing roller is fixedly connected to a first motor, a screen is obliquely installed at the lower end of the crushing box, a material pushing assembly is provided at the upper end of the screen, and a blocking curtain is installed at the end of the screen;

[0008] A discharge port is provided at the lower end of the outer wall of the compression box, a sliding door is slidably provided at the discharge port, a hydraulic cylinder is fixedly installed at the top of the compression box, and an output end of the hydraulic cylinder is connected to a compression plate through a piston rod.

[0009] Preferably, a feed inlet is provided at the top of the pulverizing box, and a liquid outlet is provided at the bottom of the pulverizing box.

[0010] Preferably, there are two crushing rollers and two first motors, and both are symmetrically arranged front to back about the feed opening.

[0011] Preferably, the pusher assembly includes a screw rod, one end of which is fixedly connected to the second motor, a pusher plate is threadedly connected to the screw rod, and the lower surface of the pusher plate is in contact with the upper surface of the screen.

[0012] Preferably, there are two screw rods and two second motors, and both are symmetrically arranged front to back with respect to the screen.

[0013] Preferably, a brush is installed at the bottom end of the push plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. This high-efficiency solid waste compression equipment can crush solid waste in advance through the crushing roller, so that large-volume solid waste is split into small pieces, which is conducive to the mixing of wastes, prevents damage to the equipment, and facilitates subsequent compression processing. The waste liquid mixed in the solid waste can be filtered through the screen to avoid the waste liquid and the organic matter in the solid waste to react and produce odor to pollute the environment. Therefore, crushing and filtering can improve the equipment's pre-treatment ability for solid waste, thereby improving the compression effect of the equipment;

[0016] 2. This high-efficiency solid waste compression equipment can drive the brush to sweep and clean the surface of the screen during the pushing process of the pushing plate to prevent solid waste debris from blocking the screen holes, thereby ensuring the smoothness of the screen feeding.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] To solve the technical problem of how to crush solid waste, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0023] A high-efficiency solid waste compression device includes a crushing box 1 and a compression box 2. A feed port 11 is provided at the top of the crushing box 1. A crushing roller 12 is movably installed at the upper end of the crushing box 1. One end of the crushing roller 12 is fixedly connected to a first motor 13. There are two crushing rollers 12 and two first motors 13, and they are both symmetrically arranged front and back about the feed port 11.

[0024] The two first motors 13 have the same rotation speed and opposite rotation directions, and drive the two crushing rollers 12 to rotate inwards.

[0025] Specifically, when domestic solid waste is put into the crushing box 1 through the feed port 11, it will directly fall into the roller gap between the two crushing rollers 12. At this time, the two first motors 13 are started, and the first motors 13 drive the crushing rollers 12 to rotate inward and crush the solid waste between the roller gaps. While the solid waste is crushed, the water absorbed inside it can be compressed to facilitate the separation of the waste liquid from the solid waste.

[0026] In order to solve the technical problem of how to separate solid waste into liquid, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0027] A liquid outlet 17 is provided at the bottom of the crushing box 1 , a screen 14 is obliquely installed at the lower end of the crushing box 1 , a material pushing assembly 15 is provided at the upper end of the screen 14 , and a curtain 16 is installed at the end of the screen 14 .

[0028] After the solid waste is crushed, it will fall directly onto the screen 14. At this time, the curtain 16 is closed to block the solid waste, so that the solid waste cannot slide into the compression box 2, so that the solid waste has enough time to separate the solid and liquid. The waste liquid mixed inside will pass through the screen 14 and fall to the bottom of the crushing box 1, and be discharged from the liquid outlet 17. After the solid-liquid separation is completed, the solid waste is pushed into the compression box 2 through the pushing component 15.

[0029] For technical questions about how the pusher assembly works, see Figure 3 , this embodiment provides the following technical solutions:

[0030] The pushing assembly 15 includes a screw rod 151, one end of which is fixedly connected to a second motor 152, a pushing plate 153 is threadedly connected to the screw rod 151, a brush 154 is installed at the bottom end of the pushing plate 153, the lower surface of the pushing plate 153 is in contact with the upper surface of the screen 14, there are two screw rods 151 and two second motors 152, and they are both symmetrically arranged front and back about the screen 14.

[0031] The two screw rods 151 are completely consistent, and the rotation speeds and directions of the two second motors 152 are also completely consistent.

[0032] Specifically, after the solid waste and liquid are separated, the two second motors 152 are started, and the two second motors 152 drive the two screw rods 151 to rotate synchronously in the same direction, driving the push plate 153 to move along the surface of the screen 14, so that the solid waste on the upper end of the screen 14 pushes the curtain 16 open and is pushed into the compression box 2. While the push plate 153 moves, the brush 154 will wipe and clean the upper surface of the screen 14 to remove the debris accumulated inside the screen hole to avoid clogging of the screen 14.

[0033] Working principle: When using this high-efficiency solid waste compression equipment, domestic solid waste is poured into the crushing box 1 from the feed port 11, and the two first motors 13 are started to drive the two crushing rollers 12 to rotate inward to crush the solid waste falling between the roller gaps. The crushed solid waste falls on the screen 14. At this time, the curtain 16 is closed to prevent the solid waste from sliding directly into the compression box 2 until the waste liquid in the solid and liquid is completely separated. Then, the two second motors 152 are started to drive the push plate 153 to move and push the solid waste into the compression box 2. The push plate 153 can clean the screen 14 while moving. After the solid waste enters the compression box 2, the hydraulic cylinder 22 is started to drive the compression plate 23 to move downward to compress the solid waste. After the compression is completed, the solid waste is discharged from the discharge port 21.
