Description

Technical Field

[0001] The invention relates to the technical field of waste treatment, and in particular to a solid waste treatment device. Background Art

[0002] In the process of demolishing and renovating old buildings, a large amount of construction waste will be generated. If these construction wastes are dumped directly without treatment, they will cause serious damage to the environment. Construction waste contains a large amount of concrete fragments and bricks. These concrete fragments and bricks can be recycled after crushing and can be used as aggregates for the production of building blocks, wall panels, wall tiles and other building materials, thus turning waste into treasure.

[0003] The antique bricks used in some antique buildings today can also use the aggregates made from the above-mentioned construction waste as raw materials for production. The surface of these antique bricks is smooth and has few pores. When these antique bricks are used to build walls, the facades of the walls often do not require any painting or decoration to create the architectural effect of ancient buildings. The production of these antique bricks often has high requirements for the uniformity and fineness of the aggregates.

[0004] The first step in producing aggregates from construction waste is crushing. In order to prevent the machine from overloading, graded construction waste crushing equipment is often used to crush the construction waste. It usually includes a multi-stage rolling section, each of which includes two parallel rolling rollers. The spacing between the two rolling rollers of the next rolling section is smaller than the spacing between the two rolling rollers of the previous rolling section, so that the multi-stage rolling section can perform progressive rolling of the construction waste. Large-diameter construction waste can be obtained through multi-stage rolling to obtain fine aggregate with smaller particle size, and the machine can be prevented from overloading during the rolling process. However, in actual use of the above-mentioned multi-stage rolling equipment, when each stage of the rolling section is used to roll the construction waste, if the particle size of the construction waste raw material is large, the construction waste is easy to slip relative to the rolling rollers under the push of the two rolling rollers, and roll on the two rolling rollers, thereby causing the relative rolling disc to slip, resulting in poor rolling efficiency and rolling effect of the rolling rollers.

[0032] like Figure 1-Figure 6 As shown, the solid waste treatment device provided by the present invention includes a rolling cavity 103, a transmission shaft 102 and a plurality of rolling discs 106, the transmission shaft 102 is vertically arranged in the rolling cavity 103, the rolling discs 106 are arranged in the vertical direction, and the transmission shaft 102 is connected to the eccentric position of each rolling disc 106, and also includes: a piston cylinder, a lever 202, a spring 204 and a plurality of grid plates 107, a piston cylinder, and a cylinder body 201 are horizontally arranged on the rolling disc 106; one end of the lever 202 is connected to the first piston 203 of the piston cylinder; the spring 204 is arranged in the inner cavity of the cylinder body 201, and the spring 204 abuts against the first piston 203, and the spring 204 It is used to apply an elastic force away from the axis line of the rolling disc 106 to the first piston 203. Under the action of the elastic force of the spring 204, the other end of the lever 202 abuts against the inner wall of the rolling cavity 103; multiple grid plates 107 are arranged in the rolling cavity 103, and a gap 104 is left between the outer wall of the rolling disc 106 and the inner wall of the rolling cavity 103. A grid plate 107 is arranged between two adjacent rolling discs 106, and each grid plate 107 is provided with a grid hole 105. The grid hole 105 is used to screen the crushed construction waste in the gap 104, and the grid hole 105 on the lower grid plate 107 has a smaller aperture than the grid hole 105 on the upper grid plate 107.

[0033] The working principle of the above embodiment is briefly described:

[0034] When the device is in use, construction waste is put into the rolling cavity 103, and the transmission shaft 102 drives each layer of the rolling disc 106 to rotate. The construction waste first flows into the grid plate 107 below the uppermost rolling disc 106, which is located between the inner wall of the rolling cavity 103 and the outer wall of the uppermost rolling disc 106. Since the transmission shaft 102 is connected to the eccentric part of the rolling disc 106, as the rolling disc 106 rotates, the construction waste on the grid plate 107 is stirred, so that the construction waste continues to roll on the grid plate 107. While rolling, the construction waste has to withstand the extrusion force applied to it by the eccentric rolling disc 106, so that the construction waste can be squeezed by the rolling disc 106 in all directions. After the construction waste is squeezed in all directions, the direction of the cracks generated inside is multi-directional. Therefore, the broken construction waste will appear in blocks with smaller particle size. Among them, construction waste with smaller particle size will pass through the grid holes 105 on the grid plate 107 and flow into the grid plate 107 of the next layer, while construction waste with larger particle size will remain on the grid plate 107 of the current layer and continue to be crushed under the stirring and crushing of the eccentric rolling disc 106 until it can pass through the grid holes 105 on the grid plate 107, and so on. Since the grid holes 105 on the lower grid plate 107 are smaller than the grid holes 105 on the upper grid plate 107, the initial particle size of the construction waste crushed by the lower rolling disc 106 is smaller than the initial particle size of the construction waste crushed by the upper rolling disc 106. Under the progressive crushing of multiple layers of rolling discs 106, the particle size of the construction waste gradually becomes smaller, thereby greatly improving the uniformity and fineness of the aggregate finally produced. When the rolling disc 106 rotates, the rolling disc 106 drives the cylinder 201 of the toggle mechanism to rotate around the axis of the rolling disc 106, and the cylinder 201 drives the first piston 203 and the toggle rod 202 to rotate around the axis of the rolling disc 106. Due to the elastic force of the spring 204, the toggle rod 202 abuts against the inner wall of the rolling cavity 103. Therefore, when the toggle rod 202 rotates around the axis of the rolling disc 106, it will drive the construction waste in the gap 104 between the inner wall of the rolling cavity 103 and the outer wall of the rolling disc 106 to rotate around the axis of the rolling disc 106. The toggle rod 202 can prevent the construction waste from slipping relative to the rolling disc 106, thereby ensuring the rolling effect of the rolling disc 106, and the toggle rod 202 can prevent the construction waste from blocking the grid holes 105 on the grid plate 107, thereby ensuring the normal operation of the grid plate 107.

[0035] The solid waste treatment device of the present invention can prevent the construction waste from slipping and rolling when the construction waste is progressively crushed, thereby ensuring the crushing effect of the construction waste and thus ensuring the uniformity and fineness of the aggregate finally produced.

[0036] On the basis of the above embodiments, in order to improve the crushing effect of the device on construction waste, the uniformity and fineness of the aggregate finally produced are further ensured.

[0037] like Figure 2 and Figure 3 As shown, the rolling disc 106 is provided with a sliding cavity 301 along its radial direction, the sliding cavity 301 is connected to the inner cavity of the cylinder body 201, the inner cavity of the cylinder body 201 is provided with hydraulic oil, and a second piston 302 is slidably connected in the sliding cavity 301, and the second piston 302 is connected to a pressure block 303. When the lever 202 moves toward the side of the axis line close to the rolling disc 106 under the pressure of the inner wall of the rolling cavity 103, the hydraulic oil in the inner cavity of the cylinder body 201 is pushed into the sliding cavity 301 by the first piston 203, thereby driving the second piston 302 to move toward the side of the axis line away from the rolling disc 106, so as to drive the pressure block 303 to squeeze the construction waste in the gap 104.

[0038] When the rolling disc 106 drives the cylinder 201 to rotate, the cylinder 201 drives the lever 202 and the first piston 203 to rotate around the axis of the rolling disc 106. Since the rolling disc 106 is eccentrically arranged relative to the transmission shaft 102, and the lever 202 abuts against the inner wall of the rolling cavity 103, under the action of the inner wall of the rolling cavity 103 and the spring 204, the lever 202 drives the piston to slide back and forth in the inner cavity of the cylinder 201, thereby reciprocatingly squeezing the hydraulic oil in the inner cavity of the cylinder 201. 01, the inner cavity of the cylinder 201 is connected, and the hydraulic oil in the inner cavity of the cylinder 201 is pushed into the sliding cavity 301 by the first piston 203, thereby driving the second piston 302 to move toward the side away from the axis of the rolling disk 106, and the second piston 302 drives the pressure block 303 to move toward the side away from the axis of the rolling disk 106, thereby applying an extrusion force along the radial direction of the rolling disk 106 to the construction waste located in the gap 104, thereby assisting the rolling disk 106 to squeeze and crush the construction waste, thereby improving the crushing effect of the device on the construction waste.

[0039] As a preferred solution, Figure 1 , Figure 4 and Figure 6 As shown, the rolling cavity 103 is a tubular structure, the transmission shaft 102 is coaxially arranged with the rolling cavity 103, the rolling disc 106 is arranged horizontally, and the lower rolling disc 106 has a larger eccentricity relative to the transmission shaft 102 than the upper rolling disc 106. Since the structures of each layer of rolling discs 106 are the same, the lower rolling disc 106 has a larger eccentricity relative to the transmission shaft 102 than the upper rolling disc 106, and the grid holes 105 on the grid plate 107 of the lower layer have a smaller aperture than the grid holes 105 on the grid plate 107 of the upper layer, therefore, under the rolling of multiple layers of rolling discs 106 with different eccentricities, it can be ensured that construction waste with smaller particle size can still be rolled by the rolling disc 106, thereby ensuring the rolling effect of the entire device, and thus greatly improving the uniformity and fineness of the aggregate finally produced.

[0040] As a preferred solution, Figure 1 , Figure 4 and Figure 6 As shown, the rolling disc 106 is provided with a mounting hole 401 concentrically arranged therewith, the transmission shaft 102 passes through the mounting hole 401, the transmission shaft 102 is provided with a through-axis hole along its radial direction, the through-axis hole is pivotally connected with a rotating shaft 402, the end of the rotating shaft 402 is provided with an external thread, the rolling disc 106 is provided with a threaded hole 403 along its radial direction, the rotating shaft 402 is connected to the threaded hole 403 via an external thread, and the eccentricity of the rolling disc 106 relative to the transmission shaft 102 can be adjusted by rotating the rotating shaft 402. By setting up a rotating shaft 402 and rotating the rotating shaft 402, under the action of the external threads at both ends of the rotating shaft 402 and the threaded holes 403 of the rolling disc 106, the rolling disc 106 is offset in the horizontal direction relative to the transmission shaft 102, so that the eccentricity of the rolling disc 106 relative to the transmission shaft 102 can be adjusted, so that the size of the minimum gap 104 between the first grinding surface and the second grinding surface can be adjusted to meet the grinding requirements of construction waste of different particle sizes, thereby further improving the crushing effect of the device on construction waste.

[0041] As a preferred solution, Figure 1-Figure 3 and Figure 5 As shown, a hopper 101 is provided at the top of the rolling cavity 103, and a partition 501 is provided at the hopper mouth 505 of the hopper 101, and a first material passing hole 502 is provided on the partition 501. A baffle 503 is provided on the transmission shaft 102, and the baffle 503 is used to block the first material passing hole 502. A second material passing hole 504 is provided on the baffle 503. When the transmission shaft 102 drives the baffle 503 to rotate, the hopper mouth 505 can be connected with the pipe hole of the rolling cavity 103 through the first material passing hole 502 and the second material passing hole 504. By setting the partition 501 and the baffle 503, as the transmission shaft 102 rotates, the transmission shaft 102 drives the rolling disc 106 to rotate while also driving the baffle 503 to rotate, until the second material hole 504 on the baffle 503 is connected with the first material hole 502 on the partition 501, and the construction waste in the hopper 101 flows through the hopper mouth 505, the first material hole 502 and the second material hole 504 and then falls onto the topmost grid plate 107 to be crushed. When this part of construction waste is crushed by the crushing disc 106 of this layer, the transmission shaft 102 drives the baffle 503 until the baffle 503 blocks the first material hole 502. At this time, the hopper mouth 505 of the hopper 101 is blocked, and the construction waste no longer continues to fall, so that the hopper 101 can intermittently deliver construction waste into the crushing cavity 103, so that the construction waste falling into the crushing cavity 103 can have sufficient time to be crushed by the crushing disc 106, thereby improving the crushing effect of the entire device on the construction waste.

[0042] As a preferred solution, Figure 1 and Figure 5As shown, a planetary gear train is provided on the transmission shaft 102, the sun gear 601 of the planetary gear train is connected to the transmission shaft 102, the ring gear 602 of the planetary gear train is connected to the side wall of the hopper mouth 505 of the hopper 101, and the planetary gear 603 of the planetary gear train is connected to the baffle 503. When the planetary gear 603 revolves around the sun gear 601, the baffle 503 is driven to rotate around the transmission shaft 102. By setting up a planetary gear system, when the transmission shaft 102 rotates, it drives the sun gear 601 of the planetary gear system to rotate. Under the action of the ring gear 602, the sun gear 601 drives the planetary gear 603 of the planetary gear system to revolve around the sun gear 601, thereby driving the baffle 503 connected to the planetary gear 603 to rotate around the transmission shaft 102. Under the deceleration transmission action of the planetary gear system, the transmission shaft 102 drives the baffle 503 to move slowly, so that the interval between the hopper 101 feeding into the crushing cavity 103 is longer, so that the construction waste can be crushed more fully, thereby further improving the fineness of the final particle size of the construction waste.

[0043] As a preferred solution, Figure 1 As shown, a guide cone 7 is provided on the transmission shaft 102, the tip of the guide cone 7 faces upward, and the bottom end of the guide cone 7 is in contact with the upper end surface of the topmost rolling disc 106. Under the action of the guide cone 7, the construction waste flowing from the hopper opening 505 is guided to the gap 104 between the inner wall of the rolling cavity 103 and the outer wall of the topmost rolling disc 106. By providing the guide cone 7, when the construction waste flows out from the hopper opening 505 of the hopper 101, since the bottom end of the guide cone 7 is in contact with the upper end surface of the topmost rolling disc 106, under the guidance of the guide cone 7, the construction waste is dispersed and flows into the gap 104 between the inner wall of the rolling cavity 103 and the outer wall of the rolling disc 106 of the topmost rolling disc 106, so that the construction waste is more evenly distributed in the gap 104, thereby further improving the rolling effect of the device on the construction waste.

[0044] As a preferred solution, Figure 1-Figure 4As shown, the inner wall of the rolling cavity 103 is the first grinding surface, the outer wall of the rolling disc 106 is the second grinding surface, and the first grinding surface and the second grinding surface are both provided with oblique grooves, and the angle between the oblique grooves and the vertical direction is an acute angle. By providing the oblique grooves, when the rolling disc 106 rotates relative to the rolling cavity 103, the first grinding surface also rotates relative to the second grinding surface, and the construction waste in the gap 104, that is, between the first grinding surface and the second grinding surface, will rotate when being rolled by the second grinding surface, and the oblique grooves can not only increase the friction between the construction waste and the first grinding surface or the second grinding surface, but also have a certain guiding effect on the construction waste due to the acute angle between the oblique grooves and the vertical direction, so that the construction waste is turned in three dimensions, so that each surface of the construction waste can be squeezed, thereby further improving the crushing effect of the device on the construction waste.

[0045] As a preferred solution, Figure 1 As shown, a hard material coating is provided on the inner wall of the rolling cavity 103. By providing a hard material coating on the inner wall of the rolling cavity 103, the hardness of the inner wall of the rolling cavity 103 can be improved to prevent the inner wall of the rolling cavity 103 from being dented under the pressure of construction waste.

[0046] As a preferred solution, Figure 1 As shown, the bottom end of the transmission shaft 102 is connected to a power device 8. By providing the power device 8, the power device 8 drives the transmission shaft 102 to rotate, thereby driving the rolling disc 106 to continuously roll the construction waste, which can ensure the rolling effect of the device on the construction waste.

[0047] As a preferred solution, Figure 1 As shown, a flow funnel 9 is provided at the bottom of the rolling cavity 103. By providing the flow funnel 9, the collection of the final aggregate can be facilitated.

[0048] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
