Description

Technical Field

[0001] The present invention belongs to the technical field of garbage treatment, and particularly relates to a garbage crusher. Background Art

[0002] In recent years, the output of urban domestic garbage in China has been continuously increasing. However, the two current main garbage treatment methods, sanitary landfill and incineration, are facing their respective problems, and it is becoming increasingly difficult to select and implement projects. Therefore, it is necessary to find a new way to truly achieve garbage reduction, harmlessness, and resource utilization.

[0003] The EMBT process mainly includes a mechanical treatment system, a biological hydrolysis system, an anaerobic system, a biological drying system, a post-separation system, and a deodorization system. Kitchen waste is first mechanically pre-treated to separate plastics and fabrics, remove metals and inert interfering substances, and the remaining materials enter the biological hydrolysis system to form a high-concentration organic slurry and an extruded solid phase. Therefore, it is necessary to provide a garbage crusher that can remove ductile impurities such as small pieces, plastic blocks, and wood impurities while crushing kitchen waste. In addition, when the garbage crusher crushes large pieces of garbage or sticky garbage, it is easy to get blocked or jammed, and automatic blockage removal needs to be realized. Summary of the Invention

[0004] The purpose of the present invention is to provide a garbage crusher that can separate ductile impurities and can achieve automatic blockage removal.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A garbage crusher includes a frame. A crushing chamber is provided inside the frame. An inlet is provided above the crushing chamber, and an outlet is provided below the crushing chamber. A first crushing roller and a second crushing roller are provided inside the crushing chamber. The first crushing roller and the second crushing roller are arranged vertically. The first crushing roller is connected to the frame through a fixed bearing seat, and the second crushing roller is connected to the frame through a movable bearing seat. The movable bearing seat is connected to the frame through an elastic guiding mechanism. The elastic guiding mechanism presses the second crushing roller towards the first crushing roller. A ductile impurity discharge port is provided on one side of the crushing chamber. The ductile impurity discharge port is connected to a discharge chamber. An impeller is provided inside the discharge chamber, and a ductile impurity discharge outlet is provided below the discharge chamber.

[0007] Preferably, the elastic guiding mechanism includes a guiding shaft, an upper support seat, a lower support seat, and a compression spring. One end of the guiding shaft is fixedly connected to the movable bearing seat, and the other end of the guiding shaft is fixedly connected to the upper support seat. The lower support seat is fixedly connected to the frame. The compression spring is sleeved on the guiding shaft, and both ends of the compression spring are respectively abutted against the upper support seat and the lower support seat.

[0008] Preferably, a plurality of lower support seat mounting seats for adjusting the mounting position of the lower support seat are provided on the frame.

[0009] Preferably, a garbage disc selection sieve is provided below the discharge port.

[0010] Preferably, an arc-shaped sieve is provided at the discharge port.

[0011] Preferably, an artificial blockage removal door communicating with the crushing chamber is provided on the frame.

[0012] (1) For the garbage crusher of the present invention, brittle and friable materials are crushed by the crushing teeth on the first crushing roller and the second crushing roller. Under the pushing and centrifugal force of the first crushing roller and the second crushing roller, the crushed small particle materials flow out from the discharge port, while the tough materials that are not easily broken are thrown by the first crushing roller and the second crushing roller towards the tough impurity discharge port, enter the discharge chamber, and are discharged towards the tough impurity discharge outlet through the impeller in the discharge chamber. In addition, when a large piece of material is stuck between the first crushing roller and the second crushing roller, the second crushing roller can automatically retreat outward by a certain distance to allow the material to fall smoothly, and under the action of the elastic guiding mechanism, the second crushing roller automatically resets.

[0013] (2) When a large piece of material is stuck between the first crushing roller and the second crushing roller, the pressure exerted by the upper support seat fixedly connected to the guiding shaft on the compression spring causes the compression spring to be compressed. The guiding shaft drives the second crushing roller to move outward, enabling the large piece of material stuck between the first crushing roller and the second crushing roller to fall smoothly. Under the action of the compression spring, the second crushing roller can automatically reset.

[0014] (3) A plurality of upper support seat mounting seats for adjusting the mounting position of the upper support seat are provided on the frame. By mounting the upper support seat on different upper support seat mounting seats, the mounting position of the second crushing roller can be changed, and thus the crushing gap between the first crushing roller and the second crushing roller can be adjusted.

[0015] (4) A garbage disc selection sieve is provided below the discharge port. The garbage disc selection sieve can further sort small-volume garbage and inert garbage. The disc-shaped sieve plate of the garbage disc selection sieve rotates to drive the garbage on the sieve to vibrate. There is a spacing between the disc-shaped sieve plates. According to the size and weight of the garbage, the sorting purpose is achieved. According to different widths, 15 to 20 sieve plates can be installed on one garbage disc selection sieve bearing. According to the required screening treatment volume, different numbers of bearings are installed. The motor drives the bearings to rotate synchronously. Other-shaped sieve plates are easily blocked by wet garbage, while the disc-shaped sieve plates will not be blocked because they keep rotating. The garbage disc selection sieve includes a disc-shaped sieve plate, a blower, and an impurity screening system. The disc-shaped sieve plate rotates to sort garbage of different sizes and weights; the blower sorts combustible garbage; the impurity screening system removes small-volume broken glass, etc.

[0016] (5) An arc-shaped sieve is provided at the discharge port. The arc-shaped sieve can perform the first screening of the materials in the crusher; in addition, the arc-shaped sieve can also prevent the materials that have not been completely crushed from falling from the discharge port, so that the materials in the crusher are fully crushed.

[0017] (6) An artificial blockage removal door communicating with the crushing chamber is provided on the frame, which is convenient for manual blockage removal and cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

SPECIFIC EMBODIMENTS

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] As Figure 1 shown, a garbage crusher includes a frame 1, and a crushing chamber 2 and a discharge chamber 9 are arranged inside the frame.

[0024] A feed inlet 3 is arranged above the crushing chamber 2, and a discharge port 4 is arranged below the crushing chamber 2. A discharge port 8 for tough impurities communicating with the discharge chamber 9 is arranged on one side of the crushing chamber 2, an impeller 10 is arranged in the discharge chamber 9, and a discharge outlet 11 for tough impurities is arranged below the discharge chamber 9.

[0025] A first crushing roller 5 and a second crushing roller 6 are arranged in the crushing chamber 2. The first crushing roller 5 and the second crushing roller 6 are arranged up and down. The first crushing roller 5 is connected to the frame 1 through a fixed bearing seat, the second crushing roller 6 is connected to the frame 1 through a movable bearing seat, and the movable bearing seat is connected to the frame 1 through an elastic guiding mechanism 7. The elastic guiding mechanism 7 pushes the second crushing roller 6 towards the first crushing roller 5.

[0026] As Figure 2As shown in the figure, in this embodiment, the elastic guiding mechanism 7 includes a guiding shaft 701, an upper support seat 702, a lower support seat 703, and a compression spring 704. One end of the guiding shaft 701 is fixedly connected to the moving bearing seat, the other end of the guiding shaft 701 is fixedly connected to the upper support seat 702, the lower support seat 703 is fixedly connected to the frame 1, the compression spring 704 is sleeved on the guiding shaft 701, and both ends of the compression spring 704 are abutted against the upper support seat 702 and the lower support seat 703 respectively.

[0027] In this embodiment, a plurality of lower support seat mounting seats for adjusting the mounting position of the lower support seat 703 are provided on the frame 1. By mounting the lower support seat 703 on different lower support seat mounting seats, the mounting position of the second crushing roller 6 can be changed, and thus the crushing gap between the first crushing roller 5 and the second crushing roller 6 can be adjusted.

[0028] In this embodiment, a waste disc screening sieve 12 is provided below the discharge port 4. The waste disc screening sieve can further separate small-volume waste and inert waste. The disc-shaped sieve plate of the waste disc screening sieve rotates to drive the waste on the sieve to vibrate. There is a gap between the disc-shaped sieve plates, and sorting is achieved according to the size and weight of the waste. According to different widths, 15 to 20 sieve plates can be installed on one waste disc screening sieve bearing. According to the required screening throughput, different numbers of bearings are installed. The motor drives the bearings to rotate synchronously. Other-shaped sieve plates are easily blocked by wet waste at the sieve holes, while the disc-shaped sieve plates will not be blocked at the sieve holes because they are constantly rotating. The waste disc screening sieve 12 includes a disc-shaped sieve plate, a blower, and an impurity screening system. The disc-shaped sieve plate sorts waste of different sizes and weights through rotation; the blower sorts combustible waste; the impurity screening system removes small-volume broken glass, etc.

[0029] It can be understood that a bar screen or a star screen can also be provided below the discharge port 4 to replace the waste disc screening sieve 12.

[0030] In this embodiment, an arc-shaped sieve 13 is provided at the discharge port 4. The arc-shaped sieve 13 can perform the first screening of the materials in the crusher; in addition, the arc-shaped sieve 13 can also prevent the materials that have not been completely crushed from falling from the discharge port 4, so that the materials in the crusher are fully crushed.

[0031] In this embodiment, a manual blockage removal door communicating with the crushing chamber 2 is provided on the frame 1, which is convenient for manual blockage removal and cleaning.

[0032] The working mode of the present invention is as follows:

[0033] After the material enters the crusher from the feed inlet 3, the crushing teeth on the first crushing roller 5 and the second crushing roller 6 in the crushing chamber 2 crush brittle and friable materials. Under the pushing and centrifugal force of the first crushing roller 5 and the second crushing roller 6, the crushed small particle materials pass through the sieve holes of the arc-shaped sieve 13 and flow out from the discharge outlet 4, while the tough materials that are not easily broken are thrown by the first crushing roller 5 and the second crushing roller 6 towards the tough impurity discharge port 8, enter the discharge chamber 9, and are discharged towards the tough impurity discharge outlet 11 through the impeller 10 in the discharge chamber 9.

[0034] In addition, when a large piece of material is stuck between the first crushing roller 5 and the second crushing roller 6, the pressure exerted by the upper support seat 702 fixedly connected to the guide shaft on the compression spring 704 causes the compression spring 704 to be compressed. The guide shaft 701 drives the second crushing roller 6 to move outward, so that the large piece of material stuck between the first crushing roller 5 and the second crushing roller 6 can fall smoothly. Under the action of the compression spring 704, the second crushing roller 6 can automatically reset.

[0035] In addition to the above preferred embodiments, the present invention has other implementation manners. Those skilled in the art can make various changes and deformations according to the present invention. As long as they do not depart from the spirit of the present invention, they should all fall within the scope defined by the appended claims of the present invention.
