Description

Technical Field

[0001] This utility model belongs to the field of construction solid waste treatment technology, specifically relating to an automatic solid waste recycling treatment device. Background Technology

[0002] Construction waste and other solid waste can be processed into recycled aggregates. While retaining their porosity, a certain amount of cementitious materials can be added to improve their strength and waterproof performance, making them a low-cost, highly absorbent artificial wetland filter material that can replace non-renewable crushed stone filter material.

[0003] Construction waste and other solid waste require crushing equipment to break them into small particles during processing. Existing technologies include a Chinese utility model patent document (CN223221919U) disclosing a feeding unit structure for construction waste processing; and another Chinese utility model patent document (CN223209529U) disclosing a sand-making device using construction waste. In these technologies, construction waste is crushed using crushing rollers. However, this type of equipment carries the risk of material ejecting from the feed inlet during the crushing process. This phenomenon, commonly referred to as "return material" or "spraying material," poses a safety hazard. Furthermore, when construction waste is fed in, it falls directly onto the crushing rollers from a height under gravity, causing instantaneous impact that creates pits or cracks on the roller surface, affecting its service life.

[0004] Therefore, it is necessary to design an automatic solid waste recycling device that can prevent material ejection, reduce safety hazards, minimize impact, and extend the service life of the crushing roller to solve the current technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic solid waste recycling device that prevents material ejection, reduces safety hazards, minimizes impact, and extends the service life of the crushing roller.

[0006] The technical solution of this utility model is as follows: an automatic solid waste recycling treatment device, including a crushing box, with openings at the top and bottom of the crushing box. A feed hopper is fixedly installed on the top opening of the crushing box. Two crushing rollers are symmetrically rotated inside the crushing box. A driving component for driving the crushing rollers to rotate is installed on the outside of the crushing box. A baffle is detachably fixedly installed on the feed hopper. The bottom of the baffle is connected to the top of the feed hopper. A feed inlet is opened on one side of the top of the baffle. A material blocking mechanism is installed on the feed inlet. A first guide plate and a second guide plate are alternately arranged inside the baffle below the feed inlet. The ends of the first guide plate and the second guide plate near the middle of the baffle are both inclined downwards.

[0007] Furthermore, the material blocking mechanism has a support plate fixedly installed at the upper end of the feed inlet, a baffle slidably installed below the support plate in the vertical direction, a drive screw threadedly connected to the support plate, the lower end of the drive screw being rotatably connected to the baffle, and a handwheel fixedly installed at the upper end of the drive screw.

[0008] Furthermore, two guide rods are symmetrically arranged on the top of the baffle, the guide rods are parallel to the drive screw, and the guide rods are slidably connected to the support plate.

[0009] Furthermore, the baffle has a cross-section in the shape of a "7", the drive screw is rotatably connected to the top of the baffle, and the outer side of the baffle is provided with a wear-resistant coating.

[0010] Furthermore, both sides of the baffle are provided with support frames that match the first guide plate and the second guide plate respectively. The first guide plate and the second guide plate are respectively installed inside the corresponding support frames, and the ends of the first guide plate and the second guide plate are detachably fixed to the support frames by bolts.

[0011] Furthermore, both the first guide plate and the second guide plate are provided with a wear-resistant coating on their outer sides.

[0012] Furthermore, a dust removal pipe connected to the interior of the baffle is fixedly installed on the top of the baffle.

[0013] Furthermore, an upper mounting edge is fixedly provided on the outer side of the bottom end of the baffle, and a lower mounting edge is fixedly provided on the outer side of the top end of the feed hopper. The upper mounting edge and the lower mounting edge are detachably and fixedly connected by a bolt and nut mechanism.

[0015] Furthermore, the driving component includes a speed reducer and a drive motor that is drivenly connected to the speed reducer, and the output end of the speed reducer is drivenly connected to the crushing roller.

[0016] The beneficial effects of this utility model are:

[0017] (1) In this utility model, the output end of the conveyor belt extends into the inside of the baffle from the feed port. The conveyor belt transports the construction solid waste into the inside of the baffle. After being guided twice by the first guide plate and the second guide plate, it falls into the inside of the crushing box from the feed hopper. The driving component drives the crushing roller to rotate to crush the construction solid waste. The crushed particles fall from the bottom of the crushing box.

[0018] (2) Through the dual blocking effect of the baffle, the first guide plate and the second guide plate, the construction solid waste and other materials that are ejected during the crushing process can be blocked, thus preventing the materials from being ejected and reducing safety hazards.

[0019] (3) During the process of construction solid waste and other materials falling from the conveyor belt to the crushing roller, the first guide plate and the second guide plate play a two-stage guiding and buffering role, which can significantly reduce the impact on the crushing roller and extend the service life of the crushing roller.

[0023] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are not intended to limit the present invention or its application or use in any way. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete, and to fully express the scope of the present invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

[0024] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0025] like Figures 1 to 3As shown, an automatic solid waste recycling device is disclosed, including a crushing box 1. The crushing box 1 has openings at both the top and bottom. A feed hopper 11 is fixedly installed on the top opening of the crushing box 1. Two crushing rollers are symmetrically rotated inside the crushing box 1 (not shown in the figure). A driving component for rotating the crushing rollers is installed on the outside of the crushing box 1. A baffle 5 is detachably fixed on the feed hopper 11. The bottom of the baffle 5 is connected to the top of the feed hopper 11. A feed inlet 51 is opened on one side of the top of the baffle 5. A baffle mechanism 8 is installed on the feed inlet 51. A first guide plate 6 and a second guide plate 7 are alternately arranged inside the baffle 5 below the feed inlet 51. The ends of the first guide plate 6 and the second guide plate 7 near the middle of the baffle 5 are both inclined downwards. In this embodiment, the output end of the conveyor belt extends into the inside of the baffle 5 through the feed inlet 51. The conveyor belt transports the construction solid waste into the inside of the baffle 5. After being guided twice by the first guide plate 6 and the second guide plate 7, the waste falls into the inside of the crushing box 1 through the feed hopper 11. The driving component drives the crushing roller to rotate and crush the construction solid waste. The crushed particles fall from the bottom of the crushing box 1. Through the double blocking effect of the baffle 5, the first guide plate 6, and the second guide plate 7, the construction solid waste and other materials that pop out during the crushing process can be blocked, preventing the materials from popping out and reducing safety hazards. During the process of the construction solid waste and other materials falling from the conveyor belt to the crushing roller, the first guide plate 6 and the second guide plate 7 play a double guiding and buffering role, which can significantly reduce the impact on the crushing roller and extend the service life of the crushing roller.

[0026] In some embodiments, the baffle mechanism 8 has a support plate 81 fixedly disposed at the upper end of the feed inlet 51, a baffle 82 slidably disposed below the support plate 81 in the vertical direction, a drive screw 84 threadedly connected to the support plate 81, the lower end of the drive screw 84 being rotatably connected to the baffle 82, and a handwheel 85 fixedly disposed at the upper end of the drive screw 84. Since the distance between the first guide plate 6 and the second guide plate 7 is fixed, the baffle 82 can block large pieces of material on the conveyor belt, preventing occasionally mixed large pieces of material from entering the baffle 5 and causing blockage between the first guide plate 6 and the second guide plate 7. Moreover, the thickness of different conveyor belts varies, causing the distance between the conveyor belt and the baffle 82 to change. By rotating the drive screw 84 through the handwheel 85, the height of the baffle 82 can be adjusted, thereby adjusting the fixed distance between different conveyor belts and the bottom of the baffle 82.

[0027] In some embodiments, as a specific implementation of the sliding arrangement of the baffle 82, two guide rods 83 are symmetrically arranged on the top of the baffle 82. The guide rods 83 are parallel to the drive screw 84 and are slidably connected to the support plate 81. The baffle 82 is vertically slidably connected to the support plate 81 through the guide rods 83 to ensure the stability of the baffle 82 moving up and down.

[0028] In some embodiments, the cross section of the baffle 82 is in the shape of a "7". The top of the "7" shaped baffle 82 provides sufficient rotational connection space for the drive screw 84. The drive screw 84 is rotatably connected to the top of the baffle 822. The outer side of the baffle 82 is provided with a wear-resistant coating to improve the wear resistance of the baffle 82 and extend its service life.

[0029] In some embodiments, both sides of the baffle 5 are provided with support frames 53 that match the first guide plate 6 and the second guide plate 7 respectively. The interior of the support frame 53 is connected to the interior of the baffle 5. The first guide plate 6 and the second guide plate 7 are respectively installed inside the corresponding support frame 53. The ends of the first guide plate 6 and the second guide plate 7 are detachably fixed to the support frame 53 by bolts. After a period of use, the first guide plate 6 and the second guide plate 7 may be damaged due to long-term collision and friction with the material. At this time, the first guide plate 6 and the second guide plate 7 can be replaced by removing the bolts on the support frame 53.

[0030] In some embodiments, the outer sides of the first guide plate 6 and the second guide plate 7 are provided with a wear-resistant coating to improve the wear resistance of the first guide plate 6 and the second guide plate 7.

[0031] In some embodiments, a dust removal pipe 52 is fixedly provided on the top of the baffle 5 and communicates with its interior. During crushing, the dust removal pipe 52 can be connected to an external dust removal device. The dust removal device draws out the dust-containing airflow through the dust removal pipe 52 and intercepts the dust through the filter screen inside the dust removal device to achieve the purpose of dust removal.

[0032] In some embodiments, an upper mounting edge 54 is fixedly provided on the outer side of the bottom end of the baffle 5, and a lower mounting edge 12 is fixedly provided on the outer side of the top end of the feed hopper 11. The upper mounting edge 54 and the lower mounting edge 12 are detachably fixedly connected by a bolt and nut mechanism. The detachable connection between the baffle 5 and the feed hopper 11 facilitates transportation, maintenance and replacement.

[0033] In some embodiments, a base frame 2 is fixedly provided on the outside of the crushing box 1. When in use, the bottom of the base frame 2 at both ends of the crushing box 1 is raised so that the crushed material can be discharged from the bottom of the crushing box 1.

[0034] In some embodiments, the drive component includes a speed reducer 3 and a drive motor 4 that is drivenly connected to the speed reducer 3, and the output end of the speed reducer 3 is drivenly connected to the crushing roller.

[0035] In the above embodiments, the wear-resistant coating on the outer side of the baffle 82, the first guide plate 6, and the second guide plate 7 is a silicon carbide or diamond coating, which has good impact resistance and wear resistance.

[0036] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0037] The embodiments described above only illustrate some implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
