Description

Technical Field

[0002] In order to promote the recycling of renewable resources, standardize the development of the renewable resource recycling industry, save resources, protect the environment, and achieve sustainable economic and social development, waste recycling has gradually become a mainstream industry. When recycling waste, some chemical and battery wastes may contain hazardous wastes, which are prone to pollution during crushing and recycling. Therefore, targeted recycling is required for multiple categories of hazardous wastes.

[0003] However, the existing multi-category hazardous waste recycling equipment still has the following defects during use:

[0004] 1. Existing hazardous waste recycling equipment uses spraying and neutralization to treat hazardous waste. However, the fine toxic dust generated after crushing is only suppressed during spraying. After dehydration, the vibration caused by subsequent transportation and treatment will still float in the air, causing air pollution.

[0005] 2. After the spray treatment, the existing hazardous waste recovery equipment will recover and recycle the excess spray treatment liquid in order to save resources. However, the lack of recovery treatment of the spray treatment liquid results in the presence of impurities in the spray treatment liquid, which reduces the subsequent treatment effect of hazardous waste. Some existing filtration-type recovery and treatment devices need to replace the filter plate after completing the filtration treatment. The operation is cumbersome and the replacement process requires shutdown. After the disassembly is completed, the fine hazardous waste captured by the filter plate needs to be recycled again. It cannot be recycled along with the treatment of hazardous waste, which increases the treatment process and reduces the recovery efficiency. Summary of the invention

DETAILED DESCRIPTION

[0035] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] A multi-class hazardous waste recycling device according to a preferred embodiment of the present invention will be described in detail below. Figure 1-Figure 3 As shown, a multi-category hazardous waste recovery equipment includes a drop pipe 1, which adopts a flat bending design. A drop port 2 is fixedly installed on the top of the left side of the drop pipe 1. The drop port 2 is used to connect with the hazardous waste crushing outlet, so that the hazardous waste after crushing can fall into the drop pipe 1. A spray bin 3 is fixedly connected to the inclined middle part of the drop pipe 1, and a wastewater treatment tank 4 is fixedly installed at the bottom end of the spray bin 3. The wastewater treatment tank 4 is connected to the spray bin 3. The upper part of the overlapped connection between the drop pipe 1 and the spray bin 3 is connected to the spray bin 3. A filter hole 11 is opened below the overlapped connection between the drop pipe 1 and the spray bin 3. The filter hole 11 is used for the falling of excess spray treatment liquid and fine waste, so that the excess spray treatment liquid and fine waste can fall into the wastewater treatment tank 4 through the filter hole 11.

[0037] A spray chamber 5 is fixedly installed on the top of the spray bin 3, and the spray chamber 5 is used for spraying downward above the spray bin 3. A circulation component 6 is arranged between the top of the spray chamber 5 and the bottom of the wastewater treatment tank 4, and the circulation component 6 is used for recycling the spray treatment liquid; a solid waste collection component 7 is arranged inside the wastewater treatment tank 4, and the solid waste collection component 7 is used for intermittently and continuously collecting solid waste after spraying treatment.

[0038] A conveyor belt 8 is provided below the bottom openings of the drop tube 1 and the blanking frame 78 to transport the waste materials discharged downward from the drop tube 1 and the blanking frame 78 after processing.

[0039] When recycling hazardous waste, the connection between the drop port 2 and the hazardous waste crushing outlet can allow the crushed hazardous waste to enter the interior of the drop pipe 1 through the drop port 2, and through the bending design of the drop pipe 1, the hazardous waste will move to the lower right side along the drop pipe 1.

[0040] While the hazardous waste is moving downward in the middle part of the drop pipe 1, the design of the spray bin 3 at the inclined part of the middle part of the drop pipe 1 and the spray chamber 5 fixedly installed at the top of the spray bin 3 can spray the treatment liquid downward inside the spray bin 3, thereby spraying and neutralizing the hazardous waste moving downward in the drop pipe 1, and suppressing the dust generated by crushing. The hazardous waste that has been sprayed will continue to fall through the drop pipe 1 to the conveyor belt 8 for collection.

[0041] During the spraying process, a filter hole 11 is provided below the joint of the drop pipe 1 and the spray bin 3, so that the raised dust and fine waste on the surface of the hazardous waste can flow downward into the wastewater treatment tank 4 along with the excess spraying treatment liquid, and the collected spraying treatment liquid can be recycled through the circulation component 6 and the solid waste collection component 7. At the same time, the generated dust and fine waste are adhered and dropped onto the conveyor belt 8 through the drop frame 78 for collection, and the hazardous waste after the spraying treatment is recycled.

[0042] Furthermore, if Figure 1 , Figure 3-Figure 7 , Fig.10As shown, the circulation component 6 includes a suction pump 61, the top of the spray chamber 5 is fixedly installed with the suction pump 61, the bottom of the suction pump 61 is connected with the inside of the spray chamber 5, and the spray treatment liquid is sucked into the spray chamber 5 for spraying, the rear end of the suction pump 61 is fixedly installed with a valve 62, the rear end of the valve 62 is fixedly installed with a connecting pipe 63, the connecting pipe 63 is used to communicate with the spray treatment liquid delivery pipe, and the spray treatment liquid contains a neutralizing agent for hazardous waste and a flocculant for adhesion of fine waste, and the hazardous waste is neutralized by the neutralizing agent. Treatment, the fine waste is made to adhere by a flocculant, a circulation pipe 64 is fixedly installed between the bottom end of the valve 62 and the inside of the bottom of the wastewater treatment tank 4, the circulation pipe 64 is used to connect the lower side of the inside of the wastewater treatment tank 4 with the valve 62, the valve 62 is used to control the connection between the connecting pipe 63 and the circulation pipe 64 and the spraying chamber 5 through the suction pump 61, and can adjust the introduction ratio of the connecting pipe 63 and the circulation pipe 64, and then can adjust the ratio of re-addition and circulation of the spray treatment liquid according to the capacity of the wastewater treatment tank 4.

[0043] A guide rail 65 is fixedly installed at the bottom end of the wastewater treatment tank 4. The guide rail 65 is annular, and ball bearings are connected to the inner and outer sides in a limited rolling manner, which is conducive to the rotation of the swivel 66. The top of the guide rail 65 is connected to the swivel 66 in a limited rotation manner. Fan blades 67 are evenly fixedly installed on the top of the swivel 66. The fan blades 67 protrude upward, and the spray treatment liquid inside the wastewater treatment tank 4 is rotated by rotating the fan blades 67. A gear ring 68 is fixedly installed on the periphery of the bottom of the swivel 66. The internal limited rotation connection gear 69 on the side of the wastewater treatment tank 4 is located on the outside of the gear ring 68 and meshes with the gear ring 68, so that the gear 69 can drive the gear ring 68 to rotate. A motor 610 is fixedly installed above the gear 69 on the side of the wastewater treatment tank 4, and the motor 610 is connected to the gear 69 in a transmission manner downward, so that the motor 610 can drive the gear 69 to rotate.

[0044] The principle of treating and recycling the spray treatment liquid entering the wastewater treatment tank 4 through the circulation component 6 is as follows:

[0045] After the dust and fine waste follow the spray treatment liquid into the wastewater treatment tank 4, the motor 610 is started to drive the motor 610 to drive the gear 69 to rotate. During the rotation of the gear 69, the mutual meshing of the gear 69 and the gear ring 68 can drive the gear ring 68 to rotate, and then drive the rotating ring 66 to rotate on the top of the guide rail 65. During the rotation of the rotating ring 66, the fan blades 67 are driven to rotate at the bottom of the wastewater treatment tank 4, so that the spray treatment liquid can be driven to rotate in the wastewater treatment tank 4. By utilizing the effect of the flocculant added to the spray treatment liquid, the dust and fine waste in the spray treatment liquid can be adhered, and during the rotation flow of the spray treatment liquid, under the action of the centripetal force, the adhered dust and fine waste will be concentrated to the center of the wastewater treatment tank 4, and the adhered dust and fine waste will be processed by the solid waste collection component 7.

[0046] In the process of treating solid waste in the spray treatment liquid, under the action of the suction pump 61, the spray treatment liquid in the wastewater treatment tank 4 can be re-sucked into the spray chamber 5 through the circulation pipe 64 to complete the recycling, and through the connection between the connecting pipe 63 and the spray treatment liquid delivery pipe, the spray treatment liquid can be replenished, and through the action of the valve 62, the ratio of spray treatment liquid replenishment and circulation can be adjusted according to the capacity in the wastewater treatment tank 4.

[0047] Furthermore, if Figure 3-Figure 6 , Figure 8-Figure 9 , Figure 11-13 As shown, the solid waste collection component 7 includes a cylindrical barrel 71, and the cylindrical barrel 71 is fixedly installed in the center of the bottom of the wastewater treatment tank 4. The cylindrical barrel 71 passes through the bottom inner wall of the wastewater treatment tank 4 from top to bottom. The inside of the cylindrical barrel 71 is slidably connected with a collecting barrel 72, and the collecting barrel 72 extends upward to the inside of the wastewater treatment tank 4. A spring 73 is fixedly connected between the outer periphery of the middle part of the collecting barrel 72 and the top of the cylindrical barrel 71. Collection grooves 74 are evenly opened on the periphery of the collecting barrel 72. The collecting grooves 74 connect the inside of the collecting barrel 72 with the outside. Solid waste can enter the inside of the collecting barrel 72 through the collecting grooves 74. The width of the collecting grooves 74 gradually decreases from the outside to the inside, so that the allowed passing area gradually becomes smaller, so that fine solid waste can easily enter the collecting barrel 72 through the collecting grooves 74, and is not easily discharged from the collecting barrel 72.

[0048] A conical column 76 is fixedly installed on the inner side of the bottom of the collecting cylinder 72 through a connecting plate 75. The connecting plate 75 is evenly distributed between the periphery of the conical column 76 and the inner wall of the bottom of the collecting cylinder 72. Water filter holes 77 are evenly opened below the collecting groove 74 on the periphery of the bottom of the collecting cylinder 72. The cone head of the conical column 76 faces upward, and there is a distance between the upper surface and the bottom end of the collecting cylinder 72. A knife edge is opened at the bottom of the connecting plate 75 so that the fine solid waste inside the collecting cylinder 72 can be discharged outward from the gap between the conical column 76 and the bottom end of the collecting cylinder 72. The outer wall of the collecting cylinder 72 and the outer wall of the bottom of the conical column 76 are both attached to the inner wall of the cylindrical cylinder 71, so that when the collecting cylinder 72 and the conical column 76 are located inside the cylindrical cylinder 71, the inner wall of the cylindrical cylinder 71 can seal the gap between the conical column 76 and the bottom end of the collecting cylinder 72.

[0049] A blanking frame 78 is fixedly installed at the bottom end of the cylindrical barrel 71, and the blanking frame 78 is connected to the cylindrical barrel 71. The length and width of the inside of the blanking frame 78 are larger than the inner hole diameter of the cylindrical barrel 71, which is convenient for the downward discharge of waste. An electric telescopic rod 79 is fixedly installed at the center of the filter hole 11 below the connection and overlap between the drop pipe 1 and the spray bin 3. A piston 710 is fixedly installed at the bottom end of the electric telescopic rod 79. The piston 710 extends downward to the inside of the collecting barrel 72. The initial position of the water filter hole 77 is located above the top of the cylindrical barrel 71, which is convenient for the discharge of excess water during the initial compression. The initial position of the piston 710 is located above the collecting groove 74 inside the collecting barrel 72, which is convenient for the piston 710 to compress the solid waste entering the collecting barrel 72 downward.

[0050] The principle of collecting solid waste using the solid waste collection component 7 is as follows:

[0051] In the process of the adhered dust and fine waste moving toward the center of the wastewater treatment tank 4 under the action of centripetal force, they can enter the interior of the collection barrel 72 through the collection groove 74. After being collected in the collection barrel 72, the piston 710 is pushed downward in the collection barrel 72 by the electric telescopic rod 79 to squeeze the adhered dust and fine waste in the collection barrel 72, so that the accumulated solid waste moves downward to the bottom of the collection barrel 72. After the piston 710 moves to the bottom of the collection groove 74 in the collection barrel 72, the water in the solid waste can be further discharged through the water filter hole 77, and the outer wall and the conical column of the collection barrel 72 are used to remove the water in the solid waste. The bottom outer wall of 76 is designed to be attached to the inner wall of the cylindrical tube 71, and the solid waste cannot be discharged outward from the gap between the conical column 76 and the bottom end of the collecting tube 72. Continuing to squeeze downward will push the compression spring 73 of the collecting tube 72 to move downward relative to the cylindrical tube 71 until the bottom of the collecting tube 72 extends downward to the inside of the blanking frame 78. The design of the blanking frame 78 having a length and width greater than the inner hole diameter of the cylindrical tube 71 can push the solid waste inside the collecting tube 72 outward from the gap between the conical column 76 and the bottom end of the collecting tube 72 to the inside of the blanking frame 78, and fall from the blanking frame 78 to the conveyor belt 8 to complete the collection.

[0052] After completing the collection of solid waste, the electric telescopic rod 79 is used to drive the piston 710 to return to its initial position upward. At the same time, the collection cylinder 72 will also return to its initial position under the action of the restoring force of the spring 73, so as to facilitate the next round of solid waste collection, thereby realizing intermittent and continuous collection of solid waste after spraying treatment without affecting the normal operation of spraying treatment and circulation.

[0053] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
