Description

Technical Field

[0001] The present invention relates to the technical field of recycling of non-ferrous metal smelting waste, and specifically to a waste collection and treatment device for non-ferrous metal smelting. Background Art

[0002] Heavy metal slag such as copper, lead, zinc, and nickel contains a large amount of iron compounds and can replace iron ore powder as a raw material for cement. After being crushed, the heavy metal slag can be used as coarse and fine aggregates for concrete. The ground slag powder can be used as an admixture for cement.

[0003] In the prior art, the crushing of heavy metal slag into coarse and fine aggregates can be completed by combining a crusher and a screening machine, while the crushing of heavy metal slag into slag powder requires first crushing the heavy metal slag into the size of coarse and fine aggregates and then pulverizing it into powder. Since it is inevitable to produce slag powder and small metal slag whose size is smaller than the smallest aggregate but larger than the slag powder during the process of crushing heavy metal slag into coarse and fine aggregates, these small metal slag and slag powder fall into the receiving device with the coarse and fine aggregates and are then screened by the screening device. However, during the process from receiving to screening, the slag powder is easily scattered into the air, polluting the air, and the mixture of the screened small metal slag and slag powder can neither be used as an aggregate nor directly mixed into the slag powder finished product, and needs to be collected and accumulated waiting for secondary crushing, resulting in reduced efficiency.

Detailed Embodiment

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 8 , a waste collection and treatment device for non-ferrous metal smelting, which is used to crush the waste of non-ferrous metal smelting into aggregates and slag powder of required specifications and separate the aggregates and slag powder. It includes a columnar tank body 1. Inside the tank body 1, a pipe 1 3 and a pipe 2 4 coaxial with the tank body 1 are sequentially arranged from bottom to top. The upper end of the pipe 1 3 and the lower end of the pipe 2 4 are fixedly connected together. An upwardly narrowing feeding chamber 31 is formed between the outer wall of the pipe 1 3 and the tank body 1 from bottom to top, and a gradually expanding cloth chamber 41 is formed between the outer wall of the pipe 2 4 and the tank body 1 from bottom to top. A spiral blade 5 is arranged in the feeding chamber 31, and the spiral blade 5 is fixed on the outer surface of the pipe 1 3. An air supply pipe 6 is fixed at the upper end of the tank body 1, and the air outlet end of the air supply pipe 6 faces the cloth chamber 41. The inlet of the air supply pipe 6 is connected to the air source outlet.

[0034] A lower crushing mechanism 7 and an upper crushing mechanism 8 are sequentially arranged in the pipe 1 3 from bottom to top; the lower end of the pipe 1 3 is inserted into the lower opening 2 of the tank body 1 and a main discharge pipe 9 is fixed. A secondary pipe 10 is fixed at the lower end of the main discharge pipe 9. A secondary discharge pipe 11 surrounding the opening 2 is fixedly connected to the lower end of the tank body 1. A grinding chamber is formed between the lower inner circumferential surface of the secondary discharge pipe 11 and the lower outer circumferential surface of the secondary pipe 10; a discharge promoting mechanism 12 is arranged between the secondary discharge pipe 11 and the main discharge pipe 9.

[0035] A guide pipe 16 is fixed at the upper end inlet of the pipe 2 4. The guide pipe 16 has a structure that is larger at the top and smaller at the bottom, and the small end of the guide pipe 16 is located in the inner cavity of the pipe 2 4 and corresponds to the feed inlet of the upper crushing mechanism 8.

[0036] A feed pipe 13 and an ash discharge pipe 14 are fixedly connected and communicated with the lower part of the outer wall of the tank body 1. The confluence of the inner cavity of the feed pipe 13 and the inner cavity of the tank body 1 is above the bottom wall of the tank body 1, and a gap is formed between it and the bottom wall of the tank body 1. A mesh plate 15 is arranged at the confluence of the inner cavity of the ash discharge pipe 14 and the inner cavity of the tank body 1. The mesh plate 15 is fixed on the ash discharge pipe 14 and abuts against the bottom wall of the tank body 1. The mesh holes below the mesh plate 15 penetrate the lower end of the mesh plate 15, as Figure 5 shown. The inlet of the feed pipe 13 is used to be connected to the outlet of the screw conveyor, and the outlet of the ash discharge pipe 14 is used to be connected to the dust collection cloth bag.

[0037] Principle of use: First, start the upper crushing mechanism 8 and the lower crushing mechanism 7 to rotate the first pipe 3, the second pipe 4, the feeding pipe 16 and the spiral blade 5. Then, send the small waste materials of non-ferrous metal smelting to be crushed into the feeding pipe 13 through the screw conveyor. The waste materials enter the lower cavity of the feeding chamber 31 through the feeding pipe 13. After that, under the rotation and transportation of the rotating spiral blade 5, they move upward from bottom to top in the feeding chamber 31 and enter the cloth chamber 41. Then, they enter the upper part of the upper crushing mechanism 8 through the inner cavity of the tank body 1 above the second pipe 4 and the inner cavity of the feeding pipe 16, and are initially crushed by the upper crushing mechanism 8;

[0038] Then, the initially crushed waste materials fall into the lower crushing mechanism 7 and are further crushed by the lower crushing mechanism 7 to form the required specification aggregates, slag powder, and fine metal slag with a specification between the aggregates and the slag powder. The aggregates, slag powder, and fine metal slag fall on the main discharge pipe 9. At the main discharge pipe 9, the discharge promoting mechanism 12 and the main discharge pipe 9 cooperate to separate the aggregates, and the aggregates are discharged from the tank body 1 through the inner cavity of the main discharge pipe 9. The slag powder and fine metal slag pass through the main discharge pipe 9 and enter the gap between the main discharge pipe 9 and the auxiliary discharge pipe 11, and then enter the grinding cavity formed between the auxiliary discharge pipe 11 and the auxiliary pipe 10 for further grinding to grind the fine metal slag into slag powder, and then discharge from the grinding cavity.

[0039] It should be noted that when the waste materials first entering the feeding chamber 31 move up to the confluence of the feeding chamber 31 and the cloth chamber 41, the gas source sends gas into the inner cavity of the tank body 1 through the air supply pipe 6. Part of the gas enters the second pipe 4 and the first pipe 3 to promote the separation of aggregates and slag powder during the crushing process. Another part of the gas enters the cloth chamber 41 and the feeding chamber 31 and moves downward from top to bottom along the spiral blade 5 to blow off the dust and impurities on the surface of the waste materials, and make the dust and impurities gather at the bottom of the inner cavity of the tank body 1. Then, they enter the dust collection cloth bag through the mesh holes on the mesh plate 15 and the inner cavity of the ash discharge pipe 14.

[0040] Effect of use: The waste crushing area is separated from the external environment by the tank body 1, which can effectively prevent the dust generated during the crushing process from entering the external environment, and can effectively reduce the pollution to the external environment; through the cooperation of the rotating spiral blade 5 and the feeding chamber 31, in the process of conveying the waste from bottom to top, large pieces of waste can be squeezed and crushed, making it more convenient and efficient for the upper crushing mechanism 8 to crush the waste. At the same time, the spiral blade 5 cooperates with the downward moving gas to clean the dust and slag on the waste surface, thereby improving the purity of the subsequent slag ash; through the material-promoting discharge mechanism 12 and the auxiliary pipe 1 0 and the main discharge pipe 9. During the rotation of pipe 3, the discharge promoting mechanism 12, the auxiliary pipe 10 and the main discharge pipe 9 rotate with the pipe 3, and the movable end of the discharge promoting mechanism 12 also reciprocates up and down, constantly reciprocating between the top and bottom of the main discharge pipe 9, pushing the aggregate above the main discharge pipe 9 to move up and down and move to the inner cavity of the main discharge pipe 9 in a rolling manner, thereby separating the aggregate, and introducing the slag ash and fine metal slag into the grinding chamber for grinding, so as to achieve the effect of directly and once obtaining aggregate and slag ash, and reduce the air pollution caused by dust when preparing aggregate and slag powder from waste materials.

[0041] To further illustrate the present invention, now combined with Figure 1 , Figures 6 to 8 The lower crushing mechanism 7, the upper crushing mechanism 8, the main discharge pipe 9, the auxiliary pipe 10, the auxiliary discharge pipe 11 and the discharge facilitating mechanism 12 are described in detail as follows:

[0042] like Figure 1 and Figure 6 As shown, the lower crushing mechanism 7 includes a crushing barrel 71, a crushing core 72 and a main shaft 73. The crushing barrel 71 is coaxially fixed on the inner circumferential surface of the tube 3, the crushing core 72 is coaxially arranged in the inner cavity of the crushing barrel 71, and a crushing cavity is formed between the crushing core 72 and the crushing barrel 71; the lower end of the main shaft 73 coaxially penetrates into the crushing core 72 and is connected and fixed to the crushing core 72.

[0043] The upper crushing mechanism 8 comprises a mounting cylinder 81, which is fixedly mounted on the inner circumferential surface of the tube 3; a mounting box 82, a crushing roller 1 87 and a crushing roller 2 88 are arranged in the inner cavity of the mounting cylinder 81; two transmission shafts 1 83 arranged horizontally and side by side are rotatably mounted in the mounting box 82, both ends of the transmission shaft 1 83 are exposed from the mounting box 82, and a crushing roller 1 87 is fixedly sleeved on the outer surface of both ends of the transmission shaft 1 83, and a transmission shaft 2 84 is respectively arranged on both sides of the mounting box 82, and a crushing roller 2 88 is fixedly sleeved on the outer surface of the two transmission shafts 2 84;

[0044] A gear 1 831 is fixed to the opposite end of the two transmission shafts 1 83 , and a gear 2 841 is meshedly connected to the sides of the two gears 1 831 , respectively. The two gears 2 841 are fixedly sleeved on the outer surfaces of the two transmission shafts 2 84 .

[0045] The upper crushing mechanism 8 also includes a gear ring 89, a main shaft 2 85 and two drive shafts 86, the two drive shafts 86 are respectively located on both sides of the main shaft 2 85; the lower end of the main shaft 2 85 passes downward and is fixedly connected to the installation box 82, the lower ends of the two drive shafts 86 extend into the installation box 82, and the lower ends of the two drive shafts 86 are respectively connected to the two transmission shafts 1 83 through a bevel gear transmission mechanism, the upper ends of the two drive shafts 86 extend to the inner side of the gear ring 89, and the outer surfaces of the upper ends of the two drive shafts 86 are formed with teeth that match the gear ring 89, and the gear ring 89 is fixed to the top wall of the tank body 1. It should be noted that the bevel gear transmission mechanism is composed of two bevel gears that are respectively fixedly connected to the drive shaft 86 and the transmission shaft 1 83 and mesh with each other.

[0046] The upper end of the main shaft 73 coaxially penetrates the main shaft 85 upward, and the main shaft 73 and the main shaft 85 rotate in cooperation. The upper end of the main shaft 85 penetrates the tank body 1 upward, and the main shaft 85 and the tank body 1 rotate in cooperation; the transmission shaft 1 83 and the transmission shaft 2 84 both penetrate and rotate to connect the mounting cylinder 81.

[0047] A motor 17 is fixed to the top of the tank body 1, and a bevel gear 18 is fixed to the output end of the motor 17. Bevel gear 2 19 and bevel gear 3 20 are meshed and connected to the bevel gear 18. Bevel gear 2 19 and bevel gear 3 20 are arranged opposite to each other up and down, and bevel gear 2 19 is fixedly connected to main shaft 1 73, and bevel gear 3 20 is fixedly connected to main shaft 2 85.

[0048] When in use, the motor 17 drives the bevel gear 18 to rotate, and the bevel gear 18 drives the bevel gear 2 19 and the bevel gear 3 20 to rotate, so that the main shaft 1 73 and the main shaft 2 85 rotate in opposite directions, the main shaft 1 73 drives the crushing core 72 to rotate, the main shaft 2 85 drives the installation box 82 to rotate, and the installation box 82 drives the transmission shaft 1 83 and the driving shaft 86 to rotate around the central axis of the main shaft 2 85, so that the installation cylinder 81 and the transmission shaft 2 84 rotate around the central axis of the main shaft 2 85, and then drives the tube 2 4 and the tube 1 3 to rotate. During the rotation process around the central axis of the main shaft 2 85, the driving shaft 86 realizes the rotation around its own central axis through the teeth and the gear ring 89. When the driving shaft 86 rotates, it drives the transmission shaft 1 83 to rotate around its own central axis through the bevel gear transmission mechanism, so that the gear 1 831 rotates, and the gear 1 831 drives the gear 2 841 to rotate, so that the crushing roller 1 87 and the crushing roller 2 88 rotate in opposite directions. The waste is crushed by the rotation of crushing roller 1 87 and crushing roller 2 88.

[0049] The tube 3 rotates, driving the crushing barrel 71 to rotate, so that the crushing barrel 71 and the crushing core 72 rotate in opposite directions to perform secondary crushing of the waste.

[0050] like Figure 7As shown, the main discharge pipe 9 includes a blanking pipe 91 and a partition plate 92. The partition plate 92 is fixed between the upper end of the blanking pipe 91 and the lower end of the first pipe 3. The center position of the partition plate 92 has a central hole 921 for communicating the inner cavity of the first pipe 3 and the inner cavity of the blanking pipe 91. The partition plate 92 between the first pipe 3 and the blanking pipe 91 gradually slopes upward from the first pipe 3 to the blanking pipe 91 and is provided with a number of through holes. The slag ash and fine metal slag generated during the crushing process fall into the gap between the blanking pipe 91 and the auxiliary discharge pipe 11 through the through holes, and then fall into the grinding chamber. The aggregate moves along the inclined partition plate 92 towards the inner cavity of the blanking pipe 91 and is discharged through the inner cavity of the blanking pipe 91.

[0051] The upper part of the auxiliary pipe 10 shrinks towards the center to form a frustum shape and is fixedly connected to the lower end of the blanking pipe 91.

[0052] During use, the first pipe 3 rotates and drives the blanking pipe 91 to rotate through the partition plate 92, thereby causing the auxiliary pipe 10 to rotate. The rotating auxiliary pipe 10 cooperates with the static auxiliary discharge pipe 11 to grind the fine metal slag falling between the auxiliary pipe 10 and the auxiliary discharge pipe 11 into powder.

[0053] As Figure 8 shown, the discharge promoting mechanism 12 includes a guide groove 121 and a connecting ring 122. The guide groove 121 is an annular wavy groove. The guide groove 121 is arranged on the upper part of the inner circumferential surface of the auxiliary discharge pipe 11 along the circumferential direction of the auxiliary discharge pipe 11. The connecting ring 122 surrounds the blanking pipe 91, and rollers 124 are embedded on the outer circumferential surface of the connecting ring 122. The rollers 124 are rotatably arranged in the guide groove 121. A plurality of spokes 123 are fixedly arranged on the inner circumferential surface of the connecting ring 122 at equal intervals along the circumferential direction. A plurality of ejector rods 125 are fixed to the upper ends of the plurality of spokes 123. The ejector rods 125 cooperate with the through holes on the partition plate 92.

[0054] The lower ends of the spokes 123 are fixed with guide plates 126. The guide plates 126 penetrate downward through the frustum-shaped auxiliary pipe 10 and extend into the inner cavity of the auxiliary pipe 10. The guide plates 126 are slidably matched with the auxiliary pipe 10.

[0055] During use, the rotating auxiliary pipe 10 drives the spokes 123, the connecting ring 122 and the ejector rods 125 to rotate through the guide plates 126, causing the rollers 124 to rotate along the guide groove 121 and move up and down reciprocally during the rotation, thereby driving the connecting ring 122, the spokes 123 and the ejector rods 125 to move up and down reciprocally, so that the upper ends of the ejector rods 125 reciprocally move between above and below the partition plate 92 by means of the through holes on the partition plate 92.

[0056] The heights of the plurality of ejector rods 125 on the same spoke 123 gradually decrease from the auxiliary discharge pipe 11 to the blanking pipe 91.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
