Description

Technical Field

[0001] This utility model relates to the technical field of solid waste treatment equipment, and in particular to a solid waste crushing device. Background Technology

[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, consumption, daily life, and other activities (the definition is broader internationally, including waste generated from animal activities). In layman's terms, it's "garbage." It mainly includes solid particles, garbage, slag, sludge, discarded products, broken utensils, defective products, animal carcasses, spoiled food, and human and animal excrement. Solid waste is diverse and can be broadly classified into three categories: industrial waste, agricultural waste, and domestic waste. Industrial waste includes mining waste rock, smelting slag, various coal gangues, slag and metal cutting fragments, building bricks, tiles, and stones; agricultural waste includes crop straw and livestock manure; and domestic waste is household garbage.

[0003] Solid waste usually needs to be crushed after recycling to facilitate storage, transportation and subsequent recycling. However, existing solid waste often contains a certain amount of wastewater during crushing. If crushed directly, it is easy to cause corrosion to the crushing rollers, which requires frequent maintenance of the crushing rollers. This is troublesome and costly, and is not conducive to subsequent waste recycling. Therefore, there is an urgent need for a crushing device that can reduce the corrosion of the crushing rollers. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a solid waste crushing device that can reduce corrosion of the crushing rollers.

[0005] The solid waste crushing device according to an embodiment of the present utility model includes:

[0006] The first box has a feed inlet at the top and a feed outlet on the side wall;

[0007] The second box is located below the feed inlet and is connected to the feed inlet. The bottom end of the second box has a discharge port and is equipped with a gate for opening and closing the discharge port.

[0008] The extrusion assembly includes two pressing parts, which are disposed on opposite sides inside the second chamber. The two pressing parts are capable of reciprocating in directions toward each other and toward each other to extrude solid waste.

[0009] The third box is located on one side of the first box and is connected to the first box through the material outlet. Two crushing rollers are rotatably arranged inside the third box.

[0010] A guide plate, one end of which is disposed in the first box and the other end passes through the material outlet and extends into the third box, is used to guide the solid waste discharged from the outlet to the two crushing rollers. The guide plate has water filtering holes.

[0011] The solid waste crushing device according to the embodiments of this utility model has at least the following beneficial effects:

[0012] In operation, the gate is first closed, and then the solid waste to be processed is poured into the space between the two pressing sections through the feed inlet. The two pressing sections reciprocate in a direction that moves closer and further apart, continuously squeezing the solid waste between them to expel the wastewater. After squeezing for a certain period, the gate is opened, allowing the solid waste to fall onto the guide plate, while the wastewater flows through the filter holes and falls below the guide plate. Simultaneously, the solid waste, guided by the guide plate, enters the third chamber and falls onto the two crushing rollers, where it is crushed. This solid waste crushing device, with the above-described structure, allows the wastewater to be expelled from the solid waste through the two pressing sections before crushing it with the crushing rollers. The wastewater is then filtered through the filter holes on the guide plate and flows below it, significantly reducing the amount of wastewater contained in the solid waste as it falls onto the crushing rollers. This reduces corrosion of the crushing rollers, decreases the frequency of maintenance, and lowers maintenance costs.

[0013] According to some embodiments of the present invention, the pressing part includes:

[0014] Pressure plate;

[0019] Two first drive units are connected to the two gates respectively to drive the gates to rotate.

[0020] According to some embodiments of the present invention, the first driving unit includes a hydraulic cylinder, one end of which is hinged to the first housing and the other end of which is hinged to the gate.

[0021] According to some embodiments of the present invention, one end of the guide plate is rotatably disposed in the first box, and the other end extends downwardly into the third box. The solid waste crushing device further includes:

[0022] A shaking mechanism is used to drive the guide plate to swing up and down reciprocally.

[0046] Solid waste usually needs to be crushed after recycling to facilitate storage, transportation and subsequent recycling. However, existing solid waste often contains a certain amount of wastewater during crushing. If it is crushed directly, it is easy to cause corrosion to the crushing rollers, which requires frequent maintenance of the crushing rollers. This is troublesome and costly, and is not conducive to subsequent waste recycling.

[0047] In response to this problem, this utility model provides a solid waste crushing device that can effectively improve the above-mentioned issues.

[0048] The following reference Figures 1 to 3 This invention describes a solid waste crushing device proposed in an embodiment of the present invention.

[0049] The solid waste crushing device according to an embodiment of the present utility model includes: a first box 100, a second box 200, a crushing assembly, a third box 400, and a guide plate 500.

[0050] The first housing 100 has a feed inlet 101 at its top and a feed outlet 102 on its side wall; for example... Figure 1 In one embodiment shown, the feed inlet 101 is located on the right side wall of the first housing 100.

[0051] The second housing 200 is located below the inlet 101, and its inner cavity communicates with the inlet 101. The bottom end of the second housing 200 has an outlet 201, and the second housing 200 is provided with a gate 210 at the outlet 201 for opening and closing the outlet 201. Figure 1 In one embodiment shown, the second housing 200 is welded to the first housing 100 as a whole.

[0052] The extrusion assembly includes two pressing sections 300, which are located on opposite sides inside the second housing 200. The two pressing sections 300 are capable of reciprocating in directions toward each other and toward each other to extrude solid waste. Figure 1 In one embodiment shown, two pressing parts 300 are located on the left and right sides inside the second housing 200.

[0053] The third chamber 400 is disposed on one side of the first chamber 100, and the inner cavity of the third chamber 400 is connected to the inner cavity of the first chamber 100 through the feed port 102. Two crushing rollers 410 are rotatably disposed inside the third chamber 400, and the two crushing rollers 410 are used to crush solid waste. Figure 1In one embodiment shown, the third housing 400 is welded to the right side of the first housing 100. Furthermore, it should be noted that the two crushing rollers 410 are connected to a power mechanism for driving their rotation. The two crushing rollers 410 rotate in opposite directions; this is a conventional technique and will not be elaborated further here.

[0054] One end of the guide plate 500 is located inside the first housing 100, and the other end passes through the feed inlet 102 and extends into the third housing 400. The guide plate 500 is located below the discharge outlet 201 and is used to guide the solid waste discharged from the discharge outlet 201 onto the two crushing rollers 410. The guide plate 500 has water filter holes for filtering out wastewater from the solid waste, allowing the wastewater to fall below the guide plate 500. Figure 1 In one embodiment shown, the guide plate 500 extends above the crushing roller 410.

[0055] In use, first close the gate 210, then pour the solid waste to be processed into the space between the two pressing sections 300 through the feed inlet 101. The two pressing sections 300 reciprocate in the direction of moving closer and further apart from each other, continuously squeezing the solid waste between the two pressing sections 300 to squeeze out the sewage from the solid waste. After squeezing for a certain period of time, open the gate 210 to let the solid waste fall onto the guide plate 500, while the sewage falls through the filter holes into the area below the guide plate 500. At the same time, the solid waste enters the third box 400 under the guidance of the guide plate 500 and falls onto the two crushing rollers 410, which crush the solid waste. The solid waste crushing device with the above-described structure can squeeze out the wastewater from the solid waste through the two pressing sections 300 before crushing the solid waste with the crushing roller 410, and filter the wastewater to the bottom of the guide plate 500 through the filter holes on the guide plate 500. This greatly reduces the amount of wastewater contained in the solid waste when it falls on the crushing roller 410 for crushing, thereby reducing the corrosion of the crushing roller 410, reducing the number of maintenance times of the crushing roller 410, and reducing maintenance costs.

[0056] Reference Figures 1 to 3 As shown, in some embodiments of this utility model, each of the two pressing parts 300 includes a pressing plate 301 and a plurality of protrusions 302. The plurality of protrusions 302 are fixed to the pressing plate 301 and evenly distributed on the surface of the pressing plate 301. The protrusions 302 are located on the opposite sides of the two pressing parts 300, that is, on the opposite sides of the two pressing plates 301. With this arrangement, when the pressing plates 301 of the two pressing parts 300 move closer to each other, they can contact the solid waste through the protrusions 302 on the pressing plate 301, squeezing the solid waste while also achieving a certain degree of crushing effect.

[0057] In some specific embodiments, such as Figure 3 As shown, protrusion 302 is cone-shaped, which can improve the crushing effect of solid waste.

[0058] It is conceivable that, in order to improve the level of automation, in some embodiments, such as Figure 1 As shown, the extrusion assembly also includes two third drive units 310, which are respectively connected to two pressing units 300 to drive the two pressing units 300 to move closer to or further away from each other. Obviously, the third drive unit 310 can be a telescopic motor, a hydraulic cylinder or a pneumatic cylinder, or other power mechanism that can meet the requirements.

[0059] Reference Figure 1 As shown, in some embodiments of this utility model, two gates 210 are provided, and the two gates 210 are respectively rotatably arranged on opposite sides of the discharge port 201; the solid waste crushing device also includes two first driving units 600, which are respectively connected to the two gates 210 to drive the gates 210 to rotate, thereby controlling the opening and closing of the discharge port 201. It can be understood that when crushing solid waste, the gates 210 need to remain closed, and the gates 210 will bear the weight of the solid waste. If a smooth opening method is used, the opening resistance is very large. Therefore, in this embodiment, the two gates 210 are rotatably arranged to reduce the resistance when opening and facilitate the discharge of solid waste from the second box 200.

[0060] Reference Figure 1 As shown, in some embodiments of this utility model, the first driving unit 600 includes a hydraulic cylinder. One end of the hydraulic cylinder is hinged to the first housing 100, and the other end is hinged to the gate 210. The hinge axis between the hydraulic cylinder and the first housing 100, and the hinge axis between the hydraulic cylinder and the gate 210, are both parallel to the rotation axis of the gate 210. Thus, the gate 210 can be driven to rotate by the extension and retraction of the hydraulic cylinder. It is understood that since the gate 210 needs to withstand the weight of the solid waste, a hydraulic cylinder is provided in this embodiment to drive the gate 210 to rotate in order to ensure the stability of the gate 210 during rotation.

[0061] Reference Figure 1 As shown, in some embodiments of this utility model, one end of the guide plate 500 is rotatably disposed inside the first box 100, and the other end of the guide plate 500 extends downward at an angle and passes through the feed port 102 to the third box 400. The solid waste crushing device also includes a shaking mechanism, which is used to drive the guide plate 500 to swing up and down around its rotation axis, thereby shaking the solid waste falling on the guide plate 500 so that it can enter the third box 400 more smoothly along the guide plate 500.

[0062] Reference Figure 1As shown, in some embodiments of this utility model, the shaking mechanism includes an eccentric wheel 700 and a second drive unit (not shown). The eccentric wheel 700 is eccentrically rotatably disposed inside the first housing 100, and the eccentric wheel 700 abuts against the lower side of the guide plate 500. The second drive unit is connected to the eccentric wheel 700 to drive the eccentric wheel 700 to rotate eccentrically. By driving the eccentric wheel 700 to rotate eccentrically through the second drive unit, in conjunction with the guide plate 500 and the gravity of the solid waste on the guide plate 500, the guide plate 500 can swing up and down around its rotation axis. The structure is simple and practical, and the eccentric wheel 700 does not need to be directly connected to the guide plate 500, making disassembly and assembly convenient.

[0063] Reference Figure 1 As shown, in some embodiments of this utility model, the crushing roller 410 is provided with a first crushing tooth 411, and the third housing 400 is provided with a second crushing tooth 401 on the opposite sides of the two crushing rollers 410 respectively. The second crushing tooth 401 is adapted to the first crushing tooth 411 to crush the solid waste on the opposite sides of the two crushing rollers 410, thereby enabling more thorough and complete crushing of the solid waste and improving the crushing effect.

[0064] Reference Figure 1 As shown, in some embodiments of this utility model, a pull-out collection box 420 is provided on the inner bottom of the third box 400. The collection box 420 is located below the two crushing rollers 410, and the top of the collection box 420 is open. By setting the collection box 420, solid waste after being crushed by the crushing rollers 410 can be collected for centralized processing.

[0065] Reference Figure 1 As shown, in some embodiments of this utility model, an outlet 103 penetrating through the first tank 100 is provided at the bottom inner side of the first tank 100. A drainage section 110 is also provided inside the first tank 100, and a drainage slope 111 is provided on the drainage section 110. The drainage slope 111 is used to guide the sewage passing through the filter holes to the outlet 103, thereby ensuring that the sewage inside the first tank 100 is fully and completely discharged, facilitating centralized sewage treatment. Figure 1 In one embodiment shown, the outlet 103 is located at the bottom right side of the first housing 100, the inclined top end of the drainage slope 111 extends to the right side wall of the first housing 100, and the inclined bottom end extends to the outlet 103.
