Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, and in particular to a non-powered crushing device and a sludge utilization system for a sludge utilization system. Background Technology

[0002] The sludge (iron oxide ash) generated during production needs to be recycled. The sludge is processed into small iron balls for reuse through the following process: sludge → drying → grinding → rotary hearth furnace (sintering to produce small iron balls).

[0003] The sludge, after being filtered in the converter workshop, is transported by truck to the shed. It contains approximately 25% moisture (the production batch requires sludge with a moisture content below 15%). During storage, due to its high moisture content, the sludge tends to clump together. To ensure the moisture content meets the requirements (below 15%) during sludge treatment, the clumps need to be dried. However, directly drying the clumps results in uneven particle size, poor drying efficiency, insufficient reduction in the furnace, and incomplete zinc extraction, leading to increased production costs. Therefore, the clumps need to be crushed before drying to ensure uniform particle size and optimal drying results.

[0004] The existing technology involves setting up a crusher at the front end of the dryer, but its purchase cost and operating cost are relatively high. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the above-mentioned problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides a non-powered pulverizing device for a sludge utilization system, comprising:

[0007] Two supports;

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0037] Reference Figures 1-2 As shown, this utility model embodiment provides a sludge utilization system, including a conveying device 1000 and a non-powered crushing device 2000.

[0038] The conveying device 1000 includes a conveyor frame 100 and a conveyor belt 200 movably connected to the conveyor frame 100 for conveying materials.

[0039] The non-powered crushing device 2000 includes two supports 300, a main shaft 400, and a hollow pressure roller 500; both ends of the main shaft 400 are rotatably connected to the two supports 300 respectively; the hollow pressure roller 500 includes two turntables 510 and a medium pressure section 520, the turntables 510 are spaced apart along the axial direction of the main shaft 400 and coaxially connected to the main shaft 400; the medium pressure section 520 includes a plurality of first pressure bars 521, the plurality of first pressure bars 521 are spaced apart circumferentially along the main shaft 400; the first pressure bars 521 are connected between the two turntables 510.

[0040] Two supports 300 are connected to the conveyor frame 100 near the two sides of the conveyor belt 200, and the hollow pressure roller 500 is located above the conveyor belt 200.

[0041] Specifically, when the conveyor belt 200 moves relative to the conveyor frame 100 to transport materials, the material on the conveyor belt 200 hits the hollow pressure roller 500, causing the hollow pressure roller 500 to rotate. When the material passes under the hollow pressure roller 500, a portion of the material is located in the gap between two adjacent first pressure bars 521, and then the first pressure bars 521 rotate and beat the material, thereby breaking it up. Therefore, this application has low manufacturing costs, as it is powered by the movement of the conveyor belt 200 and requires no power itself, thus reducing operating costs. Furthermore, this embodiment breaks up the material while it is being transported, reducing cycle time and improving the efficiency of sludge reuse production.

[0042] Furthermore, the hollow pressure roller 500 also includes two side pressure sections 530, which are respectively connected to the outer sides of the two turntables 510. Each side pressure section 530 includes a plurality of second pressure strips 531 spaced circumferentially along the turntable 510. The second pressure strips 531 are inclined, and their two ends are respectively connected to the main shaft 400 and the turntable 510. Specifically, since the conveyor belt 200 is arc-shaped, when the transport volume is relatively large, there will be material on both sides of the conveyor belt 200. Since the central pressure section 520 is horizontal, it cannot break up the material on both sides of the conveyor belt 200. Therefore, the inclined second pressure strips 531 in this application can match the shape of both sides of the conveyor belt 200, thereby breaking up the material on both sides of the conveyor belt 200. Thus, this embodiment further improves the material breaking effect and prevents unbroken material from directly entering the next process.

[0043] Furthermore, the first pressure strip 521 has an uneven texture.

[0044] Furthermore, the second pressure bar 531 has uneven textured patterns. For example, the patterns are spiral-shaped, or toothed. Specifically, the textured first pressure bar 521 and second pressure bar 531 can further and more quickly crush the material.

[0045] Furthermore, there are multiple non-powered crushing devices 2000, which are spaced apart along the conveying direction of the conveyor belt 200. Specifically, in this embodiment, multiple non-powered crushing devices 2000 are used to crush the material on the conveyor belt 200, thereby crushing the material at the synchronous position of the conveyor belt 200, making the material crushed more thoroughly.

[0046] Furthermore, along the conveying direction of the conveyor belt 200, the distance between the hollow pressure rollers 500 of the multiple non-powered crushing devices 2000 and the conveyor belt 200 gradually decreases. Specifically, in this embodiment, multiple non-powered crushing devices 2000 sequentially crush materials from large to small sizes, improving the material crushing efficiency and effect; in addition, the stress on each non-powered crushing device 2000 is reduced, thereby increasing the service life of the non-powered crushing devices 2000.

[0047] Furthermore, the distance between the hollow pressure roller 500 and the conveyor belt 200 is adjustable. Specifically, in this embodiment, the distance between the hollow pressure roller and the conveyor belt 200 is adjusted to accommodate materials placed at different heights on the conveyor belt 200 for crushing, thereby increasing its applicability.

[0048] Furthermore, the bracket 300 and the main shaft 400 are rotatably connected via a movable component 600; the bracket 300 is provided with a vertically extending oblong hole 310; the movable component 600 and the oblong hole 310 are connected by bolts 320. Specifically, in this embodiment, the height of the main shaft 400 is adjusted by connecting the movable component 600 to different positions of the oblong hole 310, that is, adjusting the distance between the hollow pressure roller 500 and the conveyor belt 200. This allows for more convenient and faster adjustment, and the structure is simple.

[0049] Furthermore, the movable component 600 includes a bearing housing 610 and a bearing 620 mounted in the bearing housing 610; the bearing housing 610 is connected to the bracket 300, and the end of the spindle 400 is connected to the bearing housing 610 via the bearing 620. Specifically, the structure of this embodiment is stable and reliable, and has a low cost.

[0050] Furthermore, the bracket 300 and the conveyor frame 100 are detachably connected by bolts. Specifically, this facilitates the installation and removal of both (the conveyor frame 100 and the bracket 300).

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
