Description

Technical Field

[0001] The invention relates to the technical field of solid waste treatment, in particular to a pulverizing mechanism for treating solid waste. Background Art

[0002] In the prior art, in the treatment of most solid wastes, it is usually necessary to first crush the solid waste through a crushing mechanism before the next step can be smoothly carried out; for example, the treatment of some waste paper requires the waste paper to be crushed before pulping; for example, glass waste needs to be crushed first and then hot-melt treated, and local wastes such as gypsum boards and foam boards all need to be crushed.

[0003] In the existing technology, the crushing mechanism used for solid waste treatment has poor crushing efficiency. Some crushing mechanisms need to be stopped for processing or charging during operation, resulting in low work efficiency. On the other hand, the crushing quality is poor. Most crushing mechanisms need to crush the solid waste into the size requirements. However, in the actual work, the common crushing mechanism only performs preliminary crushing, and the crushing quality is poor. Moreover, the solid waste that does not meet the size requirements cannot be re-crushed more conveniently, resulting in reduced work efficiency.

[0004] Therefore, in order to solve the above problems, it is necessary to develop a pulverizing mechanism for treating solid waste that has a reasonable structure and improves pulverizing quality and efficiency. Summary of the invention

[0027] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0028] like Figures 1 to 4 As shown, a pulverizing mechanism for treating solid waste includes a primary pulverizing mechanism, a secondary pulverizing mechanism and a tertiary pulverizing mechanism arranged from top to bottom; the secondary pulverizing mechanism includes a long strip pulverizing cylinder 1, the primary pulverizing mechanism is correspondingly installed at the left end and the right end of the pulverizing cylinder 1, and the tertiary pulverizing mechanism is correspondingly arranged directly below the secondary pulverizing mechanism;

[0029] The left and right ends of the crushing cylinder 1 are both correspondingly installed with a screw motor 2, and a screw shaft 3 is correspondingly installed between the screw motors 2 on both sides, and a screw feeding blade 4 is correspondingly installed on the screw shaft 3, and a primary crushing blade 5 is also installed on the screw shaft 3. The primary crushing blade 5 is arranged at the gap of the spiral feeding blade 4 and does not affect the feeding of the spiral feeding blade 4;

[0030] The screw shaft 3 is controlled to rotate forward or reversely by the screw motors 2 on both sides. When rotating forward, the feeding direction of the screw feeding blade 4 is from left to right, and when rotating reversely, the feeding direction of the screw feeding blade 4 is from right to left. The corresponding primary crushing blade 5 on the screw shaft 3 rotates accordingly to crush and cut the material in the crushing cylinder 1.

[0031] A first-stage material discharge filter 6 is also provided at the middle position of the lower end of the pulverizing cylinder 1. The first-stage material discharge filter 6 is connected to the third-stage pulverizing mechanism below, and the material falling from the first-stage material discharge filter 6 enters the third-stage pulverizing mechanism.

[0032] The primary crushing mechanism includes a vertically arranged lower barrel 7. The lower barrels 7 are correspondingly installed on the left and right sides of the crushing barrel 1, and crushing rollers 8 are correspondingly installed in the lower barrels 7 on both sides. The solid waste entering the lower barrel 7 is crushed by the crushing rollers 8 and then falls into the crushing barrel 1 from the left and right sides respectively.

[0033] The crushing rollers 8 are all provided with crushing saw teeth 9 .

[0034] The three-stage crushing mechanism includes a crushing box 10 extending downward from the left and right ends and the front and rear ends of the crushing tube 1. The length of the crushing box 10 is consistent with the length of the crushing tube 1. The crushing box 10 and the crushing tube 1 are installed in an integral manner up and down; the two side ends of the crushing box 10 are correspondingly installed with a transversely arranged reciprocating mechanism 11, and the main shafts of the reciprocating mechanisms 11 on both sides are correspondingly extended into the crushing box 10, and the shaft ends are correspondingly installed with a reciprocating plate 12, which is consistent in size with the crushing box 10 and can move left and right in the crushing box 10 under the drive of the reciprocating mechanism 11;

[0035] A plurality of crushing motors 13 are installed on the outer end surfaces of the reciprocating plates 12 on both sides. The positions of the crushing motors 13 on the left and right sides correspond to each other, and a crushing shaft 14 is installed between the corresponding crushing motors 13. The reciprocating plates 12 on both sides are connected as a whole through the connection of the crushing shaft 14, so that the reciprocating plates 12 on both sides move left and right at the same time, and each crushing shaft 14 is also installed with a secondary crushing blade 15;

[0036] The area between the reciprocating plates 12 on both sides is set as a crushing area 16; the crushing area 16 corresponds to the position of the first-level discharge filter 6 of the upper crushing cylinder 1, and the material dropped from the first-level discharge filter 6 falls into the crushing area 16 accordingly, and the moving stroke of the reciprocating plate 12 is set accordingly, so that the material dropped from the first-level discharge filter 6 always falls into the crushing area 16 and will not fall into the area outside the reciprocating plate 12.

[0037] A secondary material discharge filter 17 is provided at the lower end of the crushing box 10 , and the mesh diameter of the secondary material discharge filter 17 is smaller than that of the primary material discharge filter 6 ; and a spiral feeding mechanism is also provided at the lower end of the crushing box 10 .

[0038] The spiral feeding mechanism includes a cylindrical spiral feeding shell 18, the upper end of the spiral feeding shell 18 is an open structure, and the open upper end extends downward from the lower end surface of the crushing box 10, and the material coming down from the secondary discharge filter 17 directly falls into the spiral feeding shell 18. The lower end of the spiral feeding shell 18 is set as a semicircular structure, and the spiral feeding blade 4 is correspondingly installed in the semicircular structure, and the left end of the spiral feeding shell 18 is correspondingly installed with a spiral feeding motor 19, and the lower end of the right end is correspondingly provided with a discharge port 20.

[0039] The specific working principle of the present invention is as follows: first, the collected solid waste is fed into the first pulverizing mechanism discharge barrel on both sides. The discharge barrels on both sides are provided with pulverizing rollers. The solid waste is initially pulverized by the pulverizing rollers, and then the solid waste falls downward into the pulverizing barrel for secondary pulverization.

[0040] The pulverizing barrel in the present invention is provided with a spiral feeding blade, and a corresponding first-level crushing blade is installed. The spiral motors on both sides of the pulverizing barrel can rotate forward or reverse. Therefore, when rotating forward, the solid waste inside is driven to move from left to right by the spiral feeding blade, and is cut and crushed by the first-level crushing blade on the spiral shaft while moving. When the solid waste reaches the right side, the corresponding spiral motor is reversed, thereby driving the spiral feeding blade to reverse. The solid waste is driven by the spiral feeding blade to move to the left, and is also cut and crushed by the first-level crushing blade in this process. After crushing, the material that meets the size requirements falls from the first-level discharge filter into the pulverizing box.

[0041] The forward and reverse rotation of the spiral feeding blades enables the material to reciprocate to the left and right, and during the reciprocating motion, the material is cut and crushed by the primary crushing blade on the rotating shaft, thereby achieving primary crushing of solid waste, and until the material in the crushing barrel is crushed to meet the size requirements, it falls from the first-level discharge filter.

[0042] The material falling from the first-level discharge filter falls directly into the crushing area of ​​the crushing box, that is, the area between the two reciprocating plates; the secondary crushing mechanism includes a crushing box, which is a box structure, but the upper end of the crushing box is an integrated design extending downward from the front and rear ends and the left and right ends of the crushing barrel, so the shape structure of the reciprocating plate should be specifically set according to the cross-sectional shape of the crushing box.

[0043] The reciprocating plates on both sides are connected and installed as a whole through the middle crushing shaft, that is, the reciprocating mechanisms on both sides need to cooperate so that the reciprocating plates on both sides can move left and right; the crushing shaft is provided with a secondary crushing blade and a crushing motor, so the material falling from the first-level unloading filter will also move left and right in the crushing box driven by the left and right reciprocating plates, and will be cut and crushed by the secondary crushing blades on the crushing shaft when moving. The reciprocating plate drives the crushing blade to move on the one hand, and drives the material to move on the other hand, so that the material is crushed more thoroughly during the reciprocating movement.

[0044] In the above process, the positions of the crushing motors on the reciprocating plates on both sides can be set according to actual conditions, so that the crushing motors can cover all crushing areas in a large range and crush the materials to the greatest extent. Even if the entire area is not covered, the movement of the reciprocating plates can still fully cover the materials and crush them without leaving any dead corners. The positions of the secondary crushing blades on each crushing shaft can also be set accordingly, and the positions of the crushing blades can be staggered and overlapped to give them overlapping cutting areas, thereby improving the crushing quality of the materials.

[0045] The lower end of the crushing box is provided with a secondary discharge filter, and the lower end of the crushing box is connected to a spiral feeding mechanism. The specific setting of the spiral feeding mechanism is not much different from the prior art, but the setting of the spiral feeding shell is correspondingly different, because the crushing box is a box structure, and the lower end is actually a plate structure; and the spiral feeding shell needs to be provided with a corresponding connection with the secondary discharge filter at the lower end of the crushing box. Therefore, the spiral feeding shell is arranged as an open structure at the upper end, and extends downward from the upper end of the crushing box accordingly, and the lower end is arranged as a semicircular structure, which can be perfectly connected with the crushing box, and the overall structure is very reasonable.

[0046] The material falling from the secondary discharge filter falls directly into the spiral feeding shell, and then is sent to the discharge port on the right by the action of the spiral feeding blades to complete the discharge; the material in the upper crushing box will be crushed by the secondary crushing blades until it meets the requirements of the secondary discharge filter, and then it will fall down accordingly, which can meet the requirements of solid waste treatment.

[0047] The above specific implementation is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
