Description

Technical Field

[0001] The present invention relates to the technical field of solid waste treatment, and particularly to a solid residue recovery system for solid waste treatment. Background Art

[0002] During the process of recycling metal solid waste, some metal wastes have rust, oil stains, colloids, plastics, or concrete residues on the outside. The impurities remaining on the outside of the metal pose great difficulties for recycling. Usually, the metal solid waste needs to be crushed and then cleaned. Often, the crushed metal materials need to be transported to the cleaning tank through a conveyor belt;

[0003] Among them, waste glass fiber products are processed by mechanical crushing equipment such as crushing and grinding to make them into smaller particles or fibrous shapes, which are used as fillers for producing other composite materials and building materials. Or further heat the waste glass fiber material in an oxygen-free environment to decompose the organic matter (such as the resin matrix) into gas and oil, while the glass fiber is retained. The recycled glass fiber can be further processed and utilized, and the gas and oil generated by pyrolysis can also be recovered as fuel or chemical raw materials.

[0004] The existing patent (publication number: CN118751376B) discloses a metal solid waste recycling and treatment device. Through a linkage structure, when the metal is crushed, the conveyor belt is driven to rotate to convey the crushed waste metal. The conveyor belt is cleaned by a cleaning plate, and then the cleaned conveyor belt is cleaned and the water stains are adsorbed by a flushing component. The water stains on the conveyor belt cannot evaporate quickly, and the humid environment will cause some mechanical components of the conveyor belt to rust. Moreover, when the cleaning plate cleans the conveyor belt, dust and particles easily enter the gaps of the conveyor belt, affecting transportation;

[0005] The existing patent (publication number: CN111940469B) discloses a metal solid waste recycling and treatment system. The discharge device of this patent filters the clean water generated during cleaning into the water tank. Through the mutual cooperation of a long bar, a second motor, a transmission screw rod, a power plate, and a sliding round rod, the sliding round rod can drive the soft rod on the discharge round rod to convey the crushed metal solid waste on the filter screen to the collection box. The lifting cylinder drives the lifting plate to move upward, so that the lifting plate can lift the sliding round rod upward, enabling the crushed metal solid waste to slide into the collection box through the inclined mesh of the filter screen, and can collect the crushed and cleaned metal solid waste. This patent does not adopt a conveyor belt structure, but its transportation of the crushed material requires dumping cooperation and the action of lifting the collection box, which will both lead to the mechanical risk of particle dropping.

[0006] Regarding the risks existing in the above-mentioned patent, impurities outside the metal are easily adhered to the conveyor belt and inside the collection box. It is very difficult to fish out the traditional metal or fiberglass sent into the cleaning pool, and for the treatment of solid waste, it is often difficult to complete through a single transportation structure among multiple steps of the recycling system. It usually requires manual transfer multiple times or multiple different transportation structures for transfer. The above-mentioned transportation structure is prone to problems where small particles get stuck in the gaps during the transportation of crushed fiberglass or metal, ultimately affecting the operation of the transportation structure.

[0007] Therefore, it is necessary to provide a solid residue recycling system for solid waste treatment to solve the above technical problems. Summary of the Invention

[0008] To solve the above technical problems, the present invention provides a solid residue recycling system for solid waste treatment, which connects the recycling steps in series through a transportation structure, and at the same time avoids the problem that the traditional transportation structure is easily contaminated with metal or fiberglass impurities.

[0009] A solid residue recycling system for solid waste treatment provided by the present invention includes a solid waste crushing component, a transportation component, a transportation basket, a cleaning pool, and a drying component. The solid waste is sent into the solid waste crushing component for crushing, and falls from the outlet of the solid waste crushing component into the transportation basket on the transportation component. The two conveyor belts of the transportation component respectively wind around two transportation rollers before and after. The two conveyor belts make part of the conveyor belt located above be in a concave shape through two groups of guiding rollers. The guiding rollers are in pairs, and the two guiding rollers are arranged at different heights. The guiding roller at the higher position is arranged below the conveyor belt, and the guiding roller at the lower position is arranged above the conveyor belt. Clamping points are arranged below the two side edges of the transportation basket, and the clamping points on both sides of the transportation basket are clamped with the clamping cards on the transportation strips. The conveyor belt passing through the concave part is synchronously immersed in the cleaning pool;

[0010] A vibration part is arranged below the solid waste crushing component. The outer wall of the vibration shaft of the vibration part is evenly provided with vibration strips. The power shaft of the vibration shaft is connected with a vibration motor. The rotation of the vibration shaft drives the vibration strips to make the transportation basket vibrate up and down.

[0011] Preferably, an annular groove is opened on the outer wall of the transportation shaft for clamping the conveyor belt, and a tooth pattern structure meshing with the inner wall of the conveyor belt is arranged in the annular groove of the transportation shaft.

[0012] Preferably, the distance between the two conveyor belts is adapted to the length of the transportation basket, and the power shaft of one side of the transportation shaft is connected with a transportation motor.

[0013] Preferably, the cleaning pool is located below the concave part of the conveyor belt. A pressurized water pump is arranged outside the cleaning pool. A plurality of spray heads are arranged at equal intervals on the inner wall of the cleaning pool. The pressurized water pump is connected to all the spray heads through pipelines.

[0014] Preferably, a reflux plate is arranged along the transportation direction of the transportation component in the cleaning tank, and the reflux plate is inclined upward along the transportation direction. A drying component is arranged above the reflux plate, and the moisture of the transportation basket is removed when it passes under the drying component.

[0015] Preferably, a blower is equidistantly arranged under the drying component. When the blower is started, an air flow is generated to form an air impact on the solid waste in the transportation basket, and the moisture on the solid waste drops onto the reflux plate under the impact of the air flow.

[0016] Preferably, a discharge plate is installed on one side of the transportation shaft close to the reflux plate, and the transportation belt drives the transportation basket to be sent out along the discharge plate.

[0017] Compared with the related technology, a solid residue recovery system for solid waste treatment provided by the present invention has the following beneficial effects:

[0018] 1. Through the settings of the transportation basket, solid waste crushing component, cleaning tank and drying component, by engaging the clamping points of the transportation basket with the clamping points on the two transportation belts, when the transportation basket moves under the solid waste crushing component to pick up solid waste metal, the vibration part drives the transportation basket to vibrate up and down to make the dust adhering to the solid waste fall off. Through the two guiding shafts, the two transportation belts are in a concave shape. When the transportation basket passes through the concave part of the transportation belt, the transportation basket is immersed in the cleaning tank to complete the cleaning, and the solid waste is dried when passing through the drying component area. The transportation basket is sent out by the transportation component through the discharge plate under the transportation of the transportation belt, which is beneficial to avoid impurities on the solid waste from adhering to the transportation component and avoid the impurities falling from the solid waste from affecting the normal operation of the transportation component.

[0019] 2. Through the settings of the vibration part and the cleaning tank, by starting the vibration motor to drive the vibration roller to rotate, and then the vibration shaft and the vibration bars rotate. Through the vibration bars, the transportation basket rises and falls on the transportation belt, that is, the clamping points of the transportation basket rise and fall on the clamping points of the transportation belt, so that the dust adhering to the solid waste in the transportation basket falls off. Then the transportation basket is sent into the cleaning tank to reduce the dust particles entering the cleaning tank. By starting the pressurized water pump to wash the impurities on the solid waste with the cleaning agent in the cleaning tank, it is beneficial to complete the solid waste crushing, vibration dust removal and solid waste cleaning on one transportation component, and is beneficial to improving the process efficiency of solid waste recovery.

Detailed implementation manners

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. 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.

[0027] Embodiment 1

[0028] A solid residue recovery system for solid waste treatment includes a solid waste crushing component 1, a transport component 2, a transport basket 3, a cleaning pool 4 and a drying component 5. The solid waste is fed into the solid waste crushing component 1 for crushing, and falls from the outlet of the solid waste crushing component 1 into the transport basket 3 on the transport component;

[0029] The solid waste crushing component 1 includes two groups of crushing shafts. External solid waste metal is fed into the solid waste crushing component 1 through the feed port. The two groups of crushing shafts are driven by starting the crushing motor to engage and crush the solid waste metal, and it is discharged from the outlet of the solid waste crushing component 1. The solid waste crushing component 1 is a prior art and will not be elaborated here too much.

[0030] A vibration part 6 is arranged below the solid waste crushing component 1. The outer wall of the vibration shaft 62 of the vibration part 6 is evenly provided with vibration bars 61. The vibration bars 61 are convex, and the number of vibration bars 61 is four. The power shaft of the vibration shaft 62 is connected with a vibration motor 63. The rotation of the vibration shaft 62 drives the vibration bars 61 to make the transport basket 3 vibrate up and down. The outer wall of the vibration shaft 62 is attached to the bottom surface of the transport basket 3 located below the solid waste crushing component 1. When the vibration motor 63 drives the vibration shaft 62 and the vibration bars 61 to rotate, the convex vibration bars 61 lift the height of the transport basket 3.

[0031] By starting the vibration motor 63 to drive the vibration roller to rotate, and then the vibration shaft 62 and the vibration bar 61 rotate. Through the vibration bar 61, the transport basket 3 on the conveyor belt 22 undulates, that is, the engagement points 31 of the transport basket 3 fluctuate up and down at the engagement points of the conveyor belt 22, so that the dust adhered to the solid waste in the transport basket 3 falls off. Then the transport basket 3 is sent into the cleaning pool 4 to reduce the dust particles entering the cleaning pool 4.

[0032] The two conveyor belts 22 of the transport component 2 respectively wind around two transport rollers before and after. The two conveyor belts 22 are in the shape of an annular strip. An annular groove is provided on the outer wall of the transport shaft for engaging the conveyor belt 22. A tooth pattern structure meshing with the inner wall of the conveyor belt 22 is provided in the annular groove of the transport shaft. The tooth pattern structure on the inner wall of the conveyor belt 22 meshes with the tooth pattern structure in the annular groove of the transport roller, so that the conveyor belt 22 rotates in a cycle while the transport roller rotates;

[0033] The distance between the two conveyor belts 22 is adapted to the length of the transport basket 3. The power shaft of one side of the transport shaft is connected with a transport motor 21. The speed of the conveyor belt 22 is controlled by the transport motor 21. By controlling the transport motor 21, the transport basket 3 is paused below the solid waste crushing component 1, and the transport basket 3 reduces the transport speed in the cleaning pool 4. At the same time, the transport basket 3 reduces the transport speed above the return plate 41 to form a draining effect. A trigger switch can be set at a predetermined position. When the transport basket 3 passes through the trigger switch, the adjustment of the movement speed is completed;

[0034] In actual production, multiple annular grooves can be provided on the outer wall of the transport shaft. Then, according to the actual length of the transport basket 3, two suitable annular grooves are selected, and the two conveyor belts 22 are installed corresponding to the two suitable annular grooves, so that the two conveyor belts 22 just lift the transport basket 3. Then, by starting the transport motor 21 to drive one set of transport shafts to rotate, and then the rotation of one set of transport shafts causes the conveyor belt 22 to drive reciprocally.

[0035] The two conveyor belts 22 are made to be sunken in part by two sets of guide rollers 23. The guide rollers 23 are grouped in pairs of two, and the two guide rollers 23 are arranged at different heights. The higher guide roller 23 is arranged below the conveyor belt 22, and the lower guide roller 23 is arranged above the conveyor belt 22;

[0036] In one group, the two guide rollers 23 are arranged with the left side higher and the right side lower, so that the conveyor belt 22 slopes downward. In the other group, the two guide rollers 23 are arranged with the left side lower and the right side higher, so that the conveyor belt 22 slopes upward. Then, the part of the conveyor belt 22 located above is sunken, so that the transport basket 3 is immersed in the cleaning pool 4 when passing through the sunken part.

[0037] On both sides of the lower edge of the transport basket 3, engaging points 31 are provided. The engaging points 31 on both sides of the transport basket 3 are engaged with the engaging points on the transport strips. The conveyor belt 22 passing through the recessed part is synchronously immersed in the cleaning tank 4;

[0038] By engaging the engaging points 31 of the transport basket 3 with the engaging points on the two groups of conveyor belts 22, when the transport basket 3 moves below the solid waste crushing component 1 to pick up solid waste metal, the vibration part 6 drives the transport basket 3 to vibrate up and down so that the dust adhering to the solid waste drops off. Through the two guiding shafts, the two conveyor belts 22 are in a concave shape. When the transport basket 3 passes through the conveyor belt 22 in the recessed part, the transport basket 3 is immersed in the cleaning tank 4 to complete the cleaning;

[0039] The cleaning tank 4 is located below the recessed part of the conveyor belt 22. A pressurized water pump 43 is provided outside the cleaning tank 4. A number of spray heads 42 are equidistantly arranged on the inner wall of the cleaning tank 4. The pressurized water pump 43 is connected to all the spray heads 42 through pipelines. By starting the pressurized water pump 43, the cleaning agent in the cleaning tank 4 is pumped out and pressurized to form a water flow that is sprayed out through the spray heads 42. Then, the sprayed water flow flushes the solid waste, and the oil stains, colloids and rust on the outside of the solid waste are soaked and cleaned.

[0040] The cleaning tank 4 is filled with a metal cleaning agent, which is mainly composed of surfactants, alkaline salts and other additives, and can effectively remove the oil stains, rust and oxides on the metal surface.

[0041] Since the metal cleaning agent is usually in liquid or solid form and has good solubility, it can quickly dissolve and remove the dirt, oxides and grease on the metal surface.

[0042] The cleaning tank 4 is provided with a return plate 41 along the transport direction of the transport component 2, and the return plate 41 is inclined upward along the transport direction. A drying component 5 is provided above the return plate 41. When the transport basket 3 passes below the drying component 5, the water is removed.

[0043] A number of air blowers 51 are equidistantly arranged below the drying component 5. When the air blowers 51 are started, an air flow is generated to form an air flow impact on the solid waste in the transport basket 3. The water on the solid waste drops onto the return plate 41 under the impact of the air flow. The water flow flows into the cleaning tank 4 along the inclined return plate 41. The transport basket 3 completes the drying of the solid waste when passing through the area of the drying component 5. The transport basket 3 is sent out from the transport component 2 by the transport belt 22 through the discharge plate 34.

[0044] Among them, a discharge plate 34 is installed on one side of the transport shaft close to the return plate 41. The conveyor belt 22 drives the transport basket 3 to be sent out along the discharge plate 34, and a transmission belt is arranged outside so that the transport basket 3 is sent to the transmission belt through the discharge plate 34.

[0045] For the recycling of glass fiber, the technological process of the whole system can be increased. Replace the solid waste crushing component 1 with a cutting device, and add a vaporization device to the cutting device to form a vaporization process. The vaporization device can adopt a plasma vaporization furnace, which is a device that uses plasma technology to process glass fiber. It mainly consists of a plasma generator, a reaction chamber, a feeding system, a tail gas treatment system, etc., and then completes the cutting, vaporization, dust removal, and cleaning technological processes for the recycling of glass fiber.

[0046] Working principle: Select two matching annular grooves according to the actual length of the transport basket 3, install the two groups of conveyor belts 22 corresponding to the two matching annular grooves, so that the two groups of conveyor belts 22 just lift the transport basket 3. By engaging the clamping points 31 of the transport basket 3 with the clamping points on the two groups of conveyor belts 22, start the transport component 2 to move the transport basket 3 to the lower part of the outlet of the solid waste crushing component 1;

[0047] Feed the metal solid waste into the solid waste crushing component 1, and the solid waste is crushed by the solid waste crushing component 1. Start the crushing motor to drive the two groups of crushing shafts to rotate to crush the metal solid waste, and the crushed metal falls into the transport basket 3 from the outlet;

[0048] Start the transport motor 21 to drive a group of transport shafts to rotate. Then, the rotation of a group of transport shafts causes the conveyor belt 22 to drive reciprocally. Through the two groups of guiding shafts, the two groups of conveyor belts 22 are in a concave shape. When the transport basket 3 passes through the concave part of the conveyor belt 22, the transport basket 3 is immersed in the cleaning pool 4 to complete the cleaning;

[0049] Start the pressurized water pump 43 to pump out and pressurize the cleaning agent in the cleaning pool 4 to form a water flow that is sprayed out through the nozzle 42. Then, the sprayed water flow flushes the solid waste, soaks and cleans the oil stains, colloids, and rust on the outside of the solid waste, and as the transport basket 3 moves along the conveyor belt 22 away from the concave part;

[0050] Start the fan 51 of the drying component 5. The fan 51 starts to generate an air flow to form an air flow impact on the solid waste in the transport basket 3. The moisture on the solid waste drops onto the return plate 41 under the impact of the air flow. The water flow flows into the cleaning pool 4 along the inclined return plate 41. The transport basket 3 completes the drying of the solid waste when passing through the area of the drying component 5, and the transport basket 3 is sent out by the transport component 2 through the discharge plate 34 under the transportation of the conveyor belt 22.

[0051] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
