Description

Technical Field

[0001] This utility model relates to the field of metal waste treatment technology, and in particular to a metal waste mixing tank. Background Technology

[0002] In the field of metal waste treatment, the batching process is an indispensable link. Its main function is to accurately proportion and fully mix different types and specifications of metal waste to provide a mixture that meets the requirements for subsequent metal recycling and processing.

[0003] Traditional processes face numerous thorny challenges. In the past, the lack of an effective and precise screening mechanism before metal scrap entered the batching tank resulted in a large influx of large or substandard scrap that did not meet particle size requirements, frequently causing tank blockages. Once a blockage occurred, companies had to shut down for cleaning, which not only consumed significant manpower and resources but also severely slowed down subsequent processes such as mixing and discharging, greatly reducing overall production efficiency. From an environmental perspective, the dust-laden gases generated during mixing within the tank previously lacked a comprehensive treatment system. Direct emission of untreated dust-laden gases allowed large particles of dust, fine impurities, odors, and harmful gases to disperse freely, causing serious pollution to the surrounding environment and failing to meet environmental standards. Furthermore, the design of past filtration devices was inadequate; the sealing covers were difficult to disassemble, and the maintenance of multi-layered filter components was extremely difficult. When filter components needed repair or replacement, it often consumed a great deal of time and effort, severely impacting equipment uptime and resulting in high maintenance costs.

[0004] To address this, a metal waste batching tank is proposed, which has the advantages of waste pre-screening, dust absorption during the batching stage, and improved maintenance efficiency, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a metal waste mixing tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a metal waste mixing tank, comprising a tank body, a first motor fixed to the top of the tank body by bolts, and a stirring paddle fixed to the output end of the first motor by a coupling; a feed nozzle connected to the left side of the top surface of the tank body, and a pretreatment unit connected to the top of the feed nozzle by a flange; a filter box fixed to the right side of the top surface of the tank body, and a dust extraction fan connected to the left side wall of the filter box by a filter screen; and an adsorption pipe connected to the tank body on the right side wall of the filter box; a second motor fixedly installed on the side of the pretreatment unit, and a transmission roller fixed to the output end of the second motor by a coupling; a stainless steel mesh belt wound around the surface of the transmission roller, and another transmission roller installed inside the stainless steel mesh belt; a waste discharge hopper welded to the end of the pretreatment unit away from the tank body; a leak-proof sealing strip fixed to the inner wall of the pretreatment unit corresponding to the edge of the stainless steel mesh belt; and a guide plate welded obliquely to the end of the stainless steel mesh belt inside the pretreatment unit.

[0007] As a further description of the above technical solution: the top surface of the filter box is fixed with a sealing cover plate by screws, and a multi-layer filter assembly is fixedly installed on the surface of the sealing cover plate. The multi-layer filter assembly consists of a coarse filter layer, a fine filter layer and an activated carbon adsorption layer, and the coarse filter layer of the multi-layer filter assembly is arranged facing the adsorption tube.

[0008] As a further description of the above technical solution: the bottom of the pretreatment unit is welded with a tree branch-shaped reinforcing bracket, and the bottom of the reinforcing bracket is fixedly connected to the outer wall of the tank by bolts. The part of the bottom of the pretreatment unit with the reinforcing bracket has an inclined structure.

[0009] As a further description of the above technical solution: a conical part is fixed to the lower part of the tank, and a valve is fixed to the bottom of the conical part. A base is provided below the conical part, and the base is composed of a metal plate and several rod-shaped legs welded to its top surface. The several rod-shaped legs of the base are all welded to the tank.

[0010] As a further description of the above technical solution: the top surface of the filter box has a maintenance port corresponding to the sealing cover plate, and a rubber sealing ring is installed between the maintenance port and the sealing cover plate.

[0011] As a further description of the above technical solution: a horn-shaped connecting nozzle is welded and installed at the bottom of the pretreatment unit, and the horn-shaped connecting nozzle is oriented towards the feed nozzle.

[0012] This utility model has the following beneficial effects: In this invention, the stainless steel mesh belt of the pretreatment unit achieves precise screening of metal waste, directly filtering out large pieces or unqualified waste that do not meet particle size requirements, preventing them from entering the tank and causing blockages. This eliminates the need for subsequent shutdowns for cleaning, ensuring smooth operation of subsequent processes such as mixing and discharging. Simultaneously, the guide plate, in conjunction with the flared connecting nozzle at the bottom of the pretreatment unit, guides qualified waste into the tank quickly. The tree-branch-shaped reinforcing support at the bottom of the pretreatment unit disperses pressure from multiple directions, preventing the pretreatment unit from shifting or being damaged due to stress. In this invention, the multi-layer filter assembly inside the filter box is equipped with a coarse filter layer, a fine filter layer, and an activated carbon adsorption layer, which can classify and treat the dust-containing gas generated in the tank: the coarse filter layer first filters large dust particles, the fine filter layer removes fine impurities, the activated carbon adsorption layer adsorbs odors and harmful gases, and finally discharges clean gas, reducing pollution to the surrounding environment. The sealing cover is fixed with screws, which is convenient to disassemble and allows for quick maintenance or replacement of the multi-layer filter assembly in the future.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] According to an embodiment of the present invention, a metal waste mixing tank is provided.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a metal waste mixing tank according to an embodiment of the present invention includes a tank body 1. A first motor 6 is bolted to the top of the tank body 1, and a stirring paddle 15 is fixed to the output end of the first motor 6 via a coupling. A feed nozzle 5 is connected to the left side of the top surface of the tank body 1, and a pretreatment unit 7 is connected to the top of the feed nozzle 5 via a flange. A filter box 10 is fixed to the right side of the top surface of the tank body 1, and a dust collector 12 is connected to the left side wall of the filter box 10 via a filter screen. An adsorption pipe 11 connected to the tank body 1 is provided on the right side wall of the filter box 10. A second motor 8 is fixedly installed on the side of the pretreatment unit 7, and the output end of the second motor 8 is fixed via a coupling. The system includes a drive roller 16, with a stainless steel mesh belt 17 wound around its surface. Another drive roller 16 is installed inside the stainless steel mesh belt 17. A waste discharge hopper 9 is welded to the end of the pretreatment unit 7 furthest from the tank 1. A leak-proof sealing strip 20 is fixed to the inner wall of the pretreatment unit 7 corresponding to the edge of the stainless steel mesh belt 17. A guide plate 18 is welded obliquely to the end of the stainless steel mesh belt 17 inside the pretreatment unit 7. To ensure stable and efficient mixing, a first motor 6 is bolted to the top of the tank 1. This bolted connection facilitates the installation and subsequent maintenance of the first motor 6, and also ensures the stability of the motor during operation. A stirring paddle 15 is precisely fixed to the output end of the first motor 6 via a coupling. The coupling effectively transmits the motor's power, allowing the stirring paddle 15 to rotate synchronously with the motor's output shaft, thereby thoroughly mixing the metal waste inside the tank 1. On the left side of the top surface of tank 1, a feed nozzle 5 is connected, serving as the channel for metal waste to enter tank 1. The top of the feed nozzle 5 is connected to a pretreatment unit 7 via a flange. The flange connection provides good sealing and connection strength, preventing leakage of waste during transport. The pretreatment unit 7 pre-treats the metal waste entering tank 1. A second motor 8 is fixedly installed on the side of the pretreatment unit 7. A drive roller 16 is fixed to the output end of the second motor 8 via a coupling. A stainless steel mesh belt 17 is wound around the surface of the drive roller 16, and another drive roller 16 is installed inside the stainless steel mesh belt 17. The two drive rollers 16 cooperate with each other, driving the stainless steel mesh belt 17 to operate smoothly under the drive of the second motor 8. During operation, the stainless steel mesh belt 17 filters out waste that does not meet the particle size requirements, preventing large or substandard waste from entering tank 1 and causing blockages, thus ensuring the smooth operation of subsequent mixing processes. The pretreatment unit 7 is welded with a waste discharge hopper 9 at the end away from the tank 1. The unqualified waste filtered by the stainless steel mesh belt 17 will be transported to the waste discharge hopper 9 along the mesh belt and discharged from the pretreatment unit 7 through the waste discharge hopper 9 so that the unqualified waste can be further processed in the future.Meanwhile, a leak-proof sealing strip 20 is fixed on the inner wall of the pretreatment unit 7 at the edge position corresponding to the stainless steel mesh belt 17. The leak-proof sealing strip 20 can fit tightly against the edge of the stainless steel mesh belt 17, effectively preventing metal waste from leaking out from the gap between the mesh belt and the inner wall of the pretreatment unit 7 during the transmission process, and ensuring the sealing of the pretreatment process. Furthermore, inside the pretreatment unit 7, corresponding to the end of the stainless steel mesh belt 17, a guide plate 18 is welded at an inclination. Metal waste that meets the particle size requirements after being screened by the stainless steel mesh belt 17 will reach the end under the conveyor belt, and then smoothly slide into the feed nozzle 5 along the inclination guide plate 18, and finally enter the tank 1. In this patent, we only use the first motor 6 and the second motor 8 without improving their structure and function. Their setting method, installation method and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. Both the first motor 6 and the second motor 8 are equipped with matching control switches. The installation position of the control switches can be selected according to the actual use requirements to facilitate operation and control by the operator. Please refer to Figure 2 The top surface of the filter box 10 is fixed with a sealing cover 13 by screws, and a multi-layer filter assembly 14 is fixedly installed on the surface of the sealing cover 13. The multi-layer filter assembly 14 consists of a coarse filter layer, a fine filter layer, and an activated carbon adsorption layer, with the coarse filter layer of the multi-layer filter assembly 14 facing the adsorption tube 11. As an important component for treating dust in the tank 1, the filter box 10 has a sealing cover 13 fixed to its top surface by screws. The screw connection facilitates the opening and closing of the sealing cover 13, making it easy to maintain and clean the internal components of the filter box 10 later. The multi-layer filter assembly 14, which consists of a coarse filter layer, a fine filter layer, and an activated carbon adsorption layer, is fixedly installed on the surface of the sealing cover 13. This multi-layer structure design enables graded filtration and purification of dust, improving the filtration effect. In this multi-layer filter assembly 14, the coarse filter layer is positioned facing the adsorption tube 11. This arrangement ensures that the dust-laden gas entering the filter box 10 from the adsorption tube 11 first passes through the coarse filter layer, which filters out larger dust particles and impurities, reducing the filtration burden on the subsequent fine filter layer and activated carbon adsorption layer. Subsequently, the gas passes through the fine filter layer and activated carbon adsorption layer in sequence. The fine filter layer further filters out fine dust, while the activated carbon adsorption layer adsorbs odors and some harmful gases in the gas, ultimately achieving a high level of cleanliness in the gas discharged from the filter box 10 and reducing pollution to the surrounding environment.

[0018] Please refer to Figure 1 and Figure 3The bottom of the pretreatment unit 7 is welded with a tree-branch-shaped reinforcing bracket 19, and the bottom of the reinforcing bracket 19 is fixedly connected to the outer wall of the tank 1 by bolts. The part of the pretreatment unit 7 with the reinforcing bracket 19 at the bottom has an inclined structure. To ensure the structural stability of the pretreatment unit 7 during operation and to avoid its position shift or damage due to its own weight and the force during waste transportation, the tree-branch-shaped reinforcing bracket 19 is welded to the bottom of the pretreatment unit 7. The tree-branch-shaped reinforcing bracket 19 can support the pretreatment unit 7 from multiple directions, disperse the pressure it receives, and improve the support strength. The bottom of the reinforcing bracket 19 is fixedly connected to the outer wall of the tank 1 by bolts. This connection method makes the pretreatment unit 7 and the tank 1 form a stable whole, further enhancing the structural stability of the entire batching tank. At the same time, the inclined structure of the part of the pretreatment unit 7 with the reinforcing bracket 19 at the bottom, in conjunction with the operation of the stainless steel mesh belt 17, is more conducive to the smooth sliding of qualified metal waste into the feed nozzle 5, improving the efficiency of waste transportation.

[0019] Please refer to Figure 1 and Figure 2 The lower part of the tank body 1 is fixed with a conical section 3, and a valve 4 is fixed at the bottom of the conical section 3. A base 2 is located below the conical section 3, and the base 2 consists of a metal plate and several rod-shaped supports welded to its top surface. All the rod-shaped supports of the base 2 are welded to the tank body 1. The design of the conical section 3 conforms to the characteristics of material flow. After the metal waste in the tank body 1 is stirred, the conical structure guides the waste to the bottom, facilitating subsequent discharge. A valve 4 is fixed at the bottom of the conical section 3, which effectively controls the opening and closing of the discharge port at the bottom of the conical section 3. By adjusting the opening and closing degree of the valve 4, the discharge speed of the waste can also be controlled to meet different production needs. Furthermore, the base 2 is located below the conical section 3, and the base 2 consists of a metal plate and several rod-shaped supports welded to its top surface. The metal plate has good load-bearing capacity, and the rod-shaped supports are evenly distributed on the top surface of the metal plate, which can evenly transfer the weight of the entire batching tank to the ground, ensuring the stability of the batching tank when placed. Meanwhile, several rod-shaped legs of the base 2 are welded to the tank body 1. The welding connection is firm and reliable, which makes the base 2 and the tank body 1 tightly connected, further improving the structural stability of the entire batching tank and preventing safety hazards such as tipping during use.

[0020] Please refer to Figure 2The top surface of the filter box 10 has a maintenance port corresponding to the sealing cover 13, and a rubber sealing ring is installed between the maintenance port and the sealing cover 13. To facilitate replacement, cleaning, and other maintenance operations of the multi-layer filter assembly 14 inside the filter box 10, a maintenance port is provided on the top surface of the filter box 10 corresponding to the sealing cover 13. The size of the maintenance port matches the sealing cover 13. When maintenance is required, simply remove the screws fixing the sealing cover 13, open the sealing cover 13, and the multi-layer filter assembly 14 can be operated through the maintenance port. Furthermore, a rubber sealing ring is installed between the maintenance port and the sealing cover 13. The rubber sealing ring has good elasticity and sealing performance, effectively filling the gap between the maintenance port and the sealing cover 13, preventing filtered gas inside the filter box 10 from leaking from the connection between the maintenance port and the sealing cover 13, ensuring that the filtration effect of the filter box 10 is not affected, and also preventing external impurities from entering the filter box 10 and contaminating the filter assembly.

[0021] Please refer to Figure 1 and Figure 2 The bottom of the pretreatment unit 7 is welded with a horn-shaped connecting nozzle, which faces the feed nozzle 5. The large end of the horn-shaped connecting nozzle is connected to the bottom of the pretreatment unit 7, and the small end faces the feed nozzle 5. This horn-shaped structure can expand the receiving range of waste materials, so that the metal waste that meets the requirements after being screened by the pretreatment unit 7 can enter the feed nozzle 5 more smoothly through the horn-shaped connecting nozzle under the guidance of the guide plate 18. This avoids the accumulation or scattering of waste materials during the transmission process, and ensures that the waste materials can enter the tank 1 stably and efficiently, providing a guarantee for the subsequent mixing process.

[0022] Working principle: In operation, the operator feeds the metal scrap to be processed onto the stainless steel mesh belt 17 of the pretreatment unit 7, starts the second motor 8, and drives the transmission roller 16 to rotate via a coupling, thereby causing the stainless steel mesh belt 17 to operate smoothly. During operation, the stainless steel mesh belt 17 uses its mesh openings to screen the scrap: scrap that meets the particle size requirements passes through the mesh and falls onto the guide plate 18 below, while large scrap that does not meet the requirements is conveyed to the waste discharge hopper 9 and discharged from the pretreatment unit 7, completing the scrap screening. During this stage, the leak-proof sealing strip 20 prevents scrap from leaking out from the gaps along the edge of the mesh belt, the tree-branch-shaped reinforcing bracket 19 ensures the stability of the pretreatment unit 7, and the guide plate 18 is inclined. Qualified scrap falling on it slides along the guide plate 18 to the trumpet-shaped connecting nozzle at the bottom of the pretreatment unit 7, and then precisely enters the feed nozzle 5 at the top of the tank 1 through the connecting nozzle, finally falling into the interior of the tank 1. Once a certain amount of waste is collected, the first motor 6 at the top of tank 1 is started. The motor output drives the stirring paddle 15 to rotate at high speed via a coupling, thoroughly mixing the waste inside the tank until it is uniformly mixed. During the mixing process, dust may be generated inside tank 1. At this time, the dust extraction fan 12 is started, drawing the dust-laden gas into the filter box 10 through the adsorption pipe 11. The dust-laden gas first contacts the coarse filter layer of the multi-layer filter assembly 14 to remove large dust particles; then it enters the fine filter layer to filter out fine impurities; finally, it passes through the activated carbon adsorption layer, where odors and harmful gases are adsorbed. The purified gas is then discharged from the filter box 10, achieving environmentally friendly operation. If maintenance of the filter assembly is required, the screws on the sealing cover 13 can be removed. After opening the cover, the filter assembly can be replaced or cleaned through the maintenance port. The rubber sealing ring ensures the seal before and after maintenance. Once the waste in the tank is mixed, the operator opens the valve 4 at the bottom of the conical part 3 and adjusts the valve opening degree to control the discharge speed as needed. Because the conical section 3 conforms to the material flow characteristics, the mixed waste inside the tank will concentrate at the bottom and be smoothly discharged through valve 4, completing the entire metal waste batching process. The base 2 supports the equipment throughout the process, ensuring the equipment remains stable during discharge.
