Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, and in particular to a conveying and screening device for solid waste treatment. Background Technology

[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, consumption, daily life and other activities. In layman's terms, it is "garbage". It mainly includes solid particles, garbage, slag, sludge, discarded products, broken utensils, defective products, animal carcasses, spoiled food, human and animal excrement, etc. Solid waste is polluting, resource-intensive and social, so it is necessary to carry out certain treatment operations.

[0003] Before processing solid waste, it is necessary to transport and screen it. The main method is to use a conveyor belt for transport. During the transport process, the larger or smaller solid waste is picked out manually. The overall operation is simple and low cost.

[0004] However, in actual operation, the overall efficiency of conveying and screening is low when using manual methods in conjunction with conveyor belts. Furthermore, the stability of conveying solid waste is generally poor when using conveyor belts to move it due to its large size. In addition, the speed and quality of manual sorting are also generally poor. Therefore, this paper proposes a conveying and screening device for solid waste treatment. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as: using manual methods in conjunction with conveyor belts for conveying and screening operations, resulting in low overall operational efficiency; and during the conveying process using conveyor belts, due to the large size of the solid waste, the stability of the conveying is generally poor because the solid waste is moved solely by the conveyor belt; and manual sorting results in both speed and quality of sorting. Therefore, this invention proposes a conveying and screening device for solid waste treatment.

[0010] Preferably, the front side of the plurality of separating rods is provided with a through hole, and both sides of the plurality of separating rods are provided with an extrusion groove. An extrusion plate is slidably connected in two of the extrusion grooves. The extrusion plate is connected to the bottom of the extrusion groove by a spring. A connecting line is fixedly connected to the extrusion plate in the extrusion groove. The connecting line passes through the extrusion groove and the through hole. A tension plate is fixedly connected to the end of the connecting line away from the extrusion groove. A vibration device for the tension plate is provided on the outside of the fixed plate.

[0011] Preferably, the vibration device includes a circular plate fixedly connected to both ends of a power rod. The side wall of the circular plate is provided with a movable groove.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Reference Figures 1-11A solid waste treatment conveying and screening device includes two fixed plates 1, two power rods 16 rotatably connected between the two fixed plates 1, both power rods 16 passing through the fixed plates 1, a common central rod 14 rotatably connected between the two fixed plates 1, two fixed grooves 11 provided on the side walls of the two fixed plates 1, the two fixed grooves 11 located between the central rod 14 and the power rods 16, a plurality of separating rods 15 provided between the two fixed plates 1, the plurality of separating rods 15 passing through the fixed grooves 11, the plurality of separating rods 15 connected to the central rod 14 through a connecting device 2, two rotating rods 18 provided between the two fixed plates 1, the two rotating rods 18 and the nearest adjacent separating rod 15 are rotatably fitted with the same sleeve plate 4, and the power rods 16 and the rotating rods 18 are fitted with the same conveyor belt 17 on their outer sides;

[0033] When solid waste needs to be conveyed and screened, the solid waste is placed on the upper side of the conveyor belt 17, and the power rod 16 is activated. The power rod 16 drives the conveyor belt 17 to move, so that the fixed waste moves out in the direction of conveyor belt 17-separation rod 15-transfer belt 17. Under the action of multiple separation rods 15, solid waste smaller than the distance between two separation rods 15 falls between the two separation rods 15, and fixed waste larger than the distance between two separation rods 15 is conveyed along the conveyor belt 17-separation rod 15-transfer belt 17, and finally the conveying and screening operation of solid waste is completed.

[0034] like Figure 2 Multiple control rods 19 are rotatably connected between the two fixed plates 1. The two outermost control rods 19 pass through the fixed plates 1, and the two outermost control rods 19 are connected to the power rods 16 through the connecting belts 191. The same power belt 12 is sleeved on the outside of the multiple control rods 19. Multiple power plates 13 are evenly fixedly connected to the outside of the power belt 12.

[0035] When using the power rod 16 and the transmission belt 17 to transport fixed waste, under the action of the connecting belt 191, the power rod 16 drives the control rod 19 to rotate, the control rod 19 drives the power belt 12 to move, the power belt 12 drives the power plate 13 to move, the power plate 13 comes into contact with the solid waste on the upper side of the transmission belt 17 or the separating rod 15, and drives the fixed waste to move, reducing the possibility of solid waste accumulating on the upper side of the transmission belt 17 or the separating rod 15, and ensuring the stability of the transport of fixed waste;

[0036] like Figure 2 , Figure 10Two regulating grooves 184 are symmetrically provided on the inner side of each of the two fixed plates 1. A regulating rod 183 is rotatably connected in the two regulating grooves 184. Two tensioning rods 182 are provided between the two fixed plates 1. The two tensioning rods 182 are located on the inner side of the transmission belt 17. The regulating rod 183 passes through the tensioning rod 182 and is threadedly connected to the tensioning rod 182. A rotating cylinder 181 is rotatably sleeved on the outer side of the regulating rod 183. The rotating cylinder 181 abuts against the inner wall of the transmission belt 17.

[0037] The regulating rod 183, tensioning rod 182, and rotating drum 181 are similar to the tensioning wheel structure in real life. Before the conveying operation, the regulating rod 183 is rotated according to the actual working conditions. The regulating rod 183 drives the tensioning rod 182 to move up and down, and the tensioning rod 182 drives the rotating drum 181 to move up and down until the conveyor belt 17 is in a taut state, thereby ensuring the transmission effect of the conveyor belt 17.

[0038] like Figure 5 , Figure 9 Multiple separating rods 15 are provided with through holes 53 on their front sides, and multiple separating rods 15 are provided with extrusion grooves 55 on both sides. Extrusion plates 51 are slidably connected in the two extrusion grooves 55. Extrusion plates 51 are connected to the bottom of extrusion grooves 55 by springs 56. Extrusion plates 51 are fixedly connected to connecting lines 54 in the extrusion grooves 55. Connecting lines 54 pass through the extrusion grooves 55 and through holes 53. A tension plate 52 is fixedly connected to the end of the connecting line 54 away from the extrusion grooves 55. A vibration device 3 for tension plate 52 is provided on the outside of the fixed plate 1.

[0039] When the stretching plate 52 moves back and forth, under the action of the spring 56, the stretching plate 52 drives the extrusion plate 51 to move through the connecting line 54. The extrusion plate 51 can perform a simple extrusion operation on the solid waste located between the two separating rods 15, and then perform a corresponding crushing operation on the corresponding solid waste, which provides convenience for subsequent solid waste treatment operations.

[0040] As shown in Figure 7, Figure 8 The vibration device 3 includes a circular plate 31 fixedly connected to both ends of the power rod 16. The side wall of the circular plate 31 is provided with a moving groove 34. A moving rod 35 is rotatably connected in the moving groove 34. A vibration rod 36 is threaded on the outside of the moving rod 35. The vibration rod 36 passes through the moving groove 34 and is slidably connected to the moving groove 34. A vibration plate 32 is provided on the outside of the two fixed plates 1. The vibration plate 32 is located on the lower side of the power rod 16 and abuts against the circular plate 31. The vibration plate 32 and the vibration rod 36 are arranged opposite to each other. A sliding plate 33 is fixedly connected to the upper side of the vibration plate 32. The tension plate 52 and the sliding plate 33 are slidably connected.

[0041] Before the power rod 16 rotates, the moving rod 35 is rotated first. The moving rod 35 drives the vibrating rod 36 to move up and down to adjust the position of the vibrating rod 36. During the rotation of the power rod 16, the power rod 16 drives the circular plate 31 to rotate. The circular plate 31 drives the moving rod 35 and the vibrating rod 36 to rotate. The vibrating rod 36 comes into contact with the vibrating plate 32 and drives the vibrating plate 32 to move. During the above adjustment process, the closer the vibrating rod 36 is to the power rod 16, the smaller the up and down movement of the vibrating plate 32, which ultimately results in a smaller movement range of the extrusion plate 51.

[0042] like Figure 4 The connecting device 2 includes two rotating plates 21 rotatably sleeved on the outside of multiple center rods 14 and separating rods 15, and the same positioning rod 22 is hinged between two adjacent rotating plates 21; two clamping plates 23 are fixedly connected to the outside of each of the two fixing plates 1, and the two clamping plates 23 are located on the upper and lower sides of the multiple rotating plates 21. Threaded rods 24 are threaded on the outside of the two clamping plates 23, and a contact plate 25 is rotatably connected on the side of the threaded rod 24 near the center rod 14. The contact plate 25 and the fixing plate 1 are slidably connected up and down. A pull ring is rotatably sleeved on the outside of the positioning rod 22, and the pull ring and the contact plate 25 are slidably connected.

[0043] Using the rotating plate 21 and the positioning rod 22, the connection between the separating rod 15 and the center rod 14 is completed. The distances between the separating rod 15 and the center rod 14 are equal. Before the conveying operation, the threaded rod 24 is rotated. The threaded rod 24 drives the contact plate 25 to move. The contact plate 25 drives the rotating plate 21 to rotate, thereby completing the adjustment of the distances between the separating rod 15 and the center rod 14, and thus completing the adjustment of the size of the solid waste screening.

[0044] In this invention, when solid waste needs to be conveyed and screened, the specific operation is as follows: First, based on the actual working conditions, determine the adjustment operation of the distance between the separating rod 15 and the center rod 14. Then, rotate the threaded rod 24, which drives the contact plate 25 to move up and down. The contact plate 25 drives the positioning rod 22 to move up and down through the pull ring. The positioning rod 22 drives the rotating plate 21 to rotate around the separating rod 15 or the center rod 14, thus completing the adjustment operation of the distance between the separating rod 15 and the center rod 14. Then, rotate the regulating rod 183, which drives the tensioning rod 182 to move up and down. The tensioning rod 182 drives the rotating drum 181 to move up and down until the conveyor belt 17 is in a taut state. Then, start the power rod 16, which drives the conveyor belt to move. Under the action of the connecting belt 191, the power rod 16 drives the control... The control lever 19 rotates, driving the power belt 12 to move. The power belt 12 drives the power plate 13 to move, placing solid waste at one end of the conveyor belt 17. The power lever 16 drives the conveyor belt 17 to move, causing the fixed waste to move out along the direction of conveyor belt 17-separation rod 15-transfer belt 17. Under the action of multiple separation rods 15, solid waste smaller than the distance between two separation rods 15 falls between the two separation rods 15, while fixed waste larger than the distance between two separation rods 15 is conveyed along the conveyor belt 17-separation rod 15-transfer belt 17, ultimately completing the conveying and screening operation of solid waste. At the same time, the power plate 13 contacts the solid waste on the upper side of the conveyor belt 17 or separation rod 15 and drives the fixed waste to move, reducing the possibility of solid waste accumulating on the upper side of the conveyor belt 17 or separation rod 15 and ensuring the stability of the fixed waste conveying.

[0045] Before the power rod 16 rotates, the moving rod 35 is rotated first. The moving rod 35 drives the vibrating rod 36 to move up and down, adjusting the position of the vibrating rod 36. During the rotation of the power rod 16, the power rod 16 drives the circular plate 31 to rotate. The circular plate 31 drives the moving rod 35 and the vibrating rod 36 to rotate. The vibrating rod 36 contacts the vibrating plate 32 and drives the vibrating plate 32 to move. During the above adjustment process, the closer the vibrating rod 36 is to the power rod 16, the smaller the up and down movement of the vibrating plate 32, which ultimately results in a smaller movement of the squeezing plate 51, completing a simple squeezing operation of the solid waste between the separation rods 15, providing convenience for subsequent processing operations.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
