Description

Technical Field

[0001] The utility model relates to the technical field of metal material processing, in particular to a dust and thin metal mixed collection and compression device. Background Art

[0002] In the process of processing metal foil in various industries, a lot of continuous long strips of metal thin materials or segmented metal thin materials, i.e. scraps, are often produced through processes such as rolling, die cutting and grinding. These scraps can be collected or recycled for secondary use. In the process of collecting these scraps, there are the following problems:

[0003] (1) Thin metal materials take up a large volume and are mainly collected in large metal boxes or long plastic bags. After being collected, the thin materials still take up a large volume and need to be transferred using a dedicated trailer, which wastes a lot of space for storage and is inconvenient for site maintenance.

[0004] (2) As the processing speed of the production line is generally fast, it is necessary to assign special personnel to handle it. The manual processing interval is short, the collection work intensity is high, and the human resource cost is high;

[0005] (3) Due to the processing technology, these scraps are usually mixed with a lot of metal dust. The ordinary treatment method will cause the dust to float in the air when the scraps are collected and processed, which will pollute the production dust-free workshop. When the metal dust is more concentrated and forms a dust cloud, there will be a higher risk of explosion, which may endanger personal safety.

[0006] Therefore, there is an urgent need for a device to separate the metal sheet and the dust for separate treatment, which can not only reduce the maintenance cost of the metal sheet, but also ensure that it does not affect the dust-free workshop, while reducing the explosion risk caused by the metal dust. Utility Model Content

[0007] In view of the problems of inconvenient site maintenance, serious waste of human resources, pollution of clean workshops and explosion risks in the existing mixed processing of dust and thin metals, the present application provides a dust and thin metal mixed collection and compression device.

[0008] The above invention objectives of the present application are achieved through the following technical solutions:

[0009] A separation mechanism, wherein the separation mechanism is used to screen the flowing gas inside the separation mechanism into dust-containing gas and metal thin material;

[0010] A filtering mechanism, the filtering mechanism is connected to the separation mechanism and is used to filter dust in the dust-laden gas;

[0011] An inert powder adding mechanism; the inert powder adding mechanism is arranged in communication between the separation mechanism and the filtering mechanism, and the inert powder adding mechanism is used to add inert powder to the dust-containing gas being transported;

[0012] A compression mechanism; the compression mechanism is connected to the separation mechanism, and is used to collect and compress the metal thin material;

[0013] A power gas source is used to provide a negative pressure environment for the gas inside the separation mechanism, so that the gas passes through the separation mechanism, the inert powder adding mechanism and the filtering mechanism in sequence.

[0014] By adopting the above technical scheme, under the action of the power gas source, dust and metal thin materials can be guided to flow in a directional manner with the air flow inside the separation mechanism. After the separation mechanism screens the flowing gas into dust-containing gas and metal thin materials, they are processed separately, that is, the dust-containing gas is filtered by the filtering mechanism, and the metal thin materials are compressed by the compression mechanism to avoid dust mixing with the metal thin materials and reduce the possibility of polluting the dust-free workshop. In addition, under the action of the inert powder adding mechanism, inert dust is mixed in the dust-containing airflow, which can increase the minimum ignition energy of the mixed metal dust, thereby reducing the risk of explosion and improving the safety of on-site work. At the same time, the high degree of automation can reduce human resource costs.

[0018] By adopting the above technical solution, since the air inlet is arranged in the lower buffer zone, when external dust and metal thin materials enter the separation chamber with the airflow, the airflow passes through the first screen plate upward according to the guiding direction and enters the upper air filter area, and then enters the filtering mechanism. At this time, the metal thin materials are accumulated under the screen plate under the interaction of the airflow and the first screen plate. After the metal thin materials accumulate to a certain amount, the pulse backblowing device is started, so that the accumulated metal thin materials are blown into the compression mechanism for the compression process, thereby realizing the separation of the dust-containing gas and the metal thin materials.

[0020] By adopting the above technical solution, a connection point connected to the filter mechanism is set in the lower buffer zone, which can allow part of the escaped dust affected by gravity to enter the filter mechanism from the lower buffer zone along with the airflow, thereby improving the filtration efficiency, and by setting a second screen plate, it can effectively resist the passage of thin metal materials. At the same time, under the action of the pulse backblowing device, the high-pressure pulse airflow enters the compression mechanism for the compression process.

[0025] In a preferred example, the present application can be further configured as follows: the primary filtering device includes a mounting plate, the mounting plate is provided with a plurality of filter cartridges, the filter cartridges are used to filter dust, and a second pulse back-blow device is provided between the mounting plate and the secondary filtering device, the second pulse back-blow device is used to transport the dust accumulated on the surface of the filter cartridges into the dust container.

[0026] By adopting the above technical solution and setting up a number of filter cartridges, it is possible to perform preliminary large-scale filtration on the dust-laden airflow. When the thickness of the dust layer on the surface of the filter cartridge reaches a level that affects the filtering performance of the filter cartridge, the second pulse back-blow device is started to transport the dust accumulated on the surface of the filter cartridge to the dust container through a high-pressure pulse airflow.

[0027] In a preferred example, the present application can be further configured as follows: the secondary filtering device is a high-efficiency filter.

[0028] By adopting the above technical solution, the high-efficiency filter can capture dust particles larger than 0.5um and various suspended matter, and is suitable for secondary filtration conditions.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. Under the action of the power gas source, the dust and metal thin materials can be guided to flow in a directional manner with the air flow inside the separation mechanism.

In addition, under the action of the inert powder adding mechanism, the dust-containing air flow is mixed with inert dust, which can increase the minimum ignition energy of the mixed metal dust, thereby reducing the risk of explosion and improving the safety of on-site work.

[0047] A dust and thin metal mixed collection and compression device of the present application is described below with reference to the accompanying drawings.

[0048] Reference Figures 1 to 7 The dust and thin metal mixed collection and compression device comprises a separation mechanism 1, a filtering mechanism 2, an inert powder adding mechanism 3, a compression mechanism 4 and a power gas source 5. The separation mechanism 1 is used to screen the flowing gas inside it into dust-containing gas and metal thin material. The filtering mechanism 2 is connected to the separation mechanism 1, and the filtering mechanism 2 is used to filter the dust in the dust-containing gas. The inert powder adding mechanism 3 is connected between the separation mechanism 1 and the filtering mechanism 2. The inert powder adding mechanism 3 is used to add inert powder to the dust-containing gas being transported. The compression mechanism 4 is connected to the separation mechanism 1, and the compression mechanism 4 is used to collect and compress the metal thin material. The power gas source 5 is used to provide a negative pressure environment for the gas inside the separation mechanism 1, so that the gas passes through the separation mechanism 1, the inert powder adding mechanism 3 and the filtering mechanism 2 in sequence. It also includes a chassis 6, the separation mechanism 1, the filtering mechanism 2, the inert powder adding mechanism 3 and the filtering mechanism 2 The inert powder adding mechanism 3, the compression mechanism 4 and the power gas source 5 are sequentially arranged inside the chassis 6 along the conveying direction of the airflow. The chassis 6 provides an installation position and a closed environment for each mechanism. Under the action of the power gas source 5, the dust and the metal sheet can be guided to flow in a directional manner inside the separation mechanism 1 along the airflow. After the separation mechanism 1 screens the flowing gas into dust-containing gas and metal sheet, they are processed separately, that is, the dust-containing gas is filtered through the filtering mechanism 2, and the metal sheet is compressed through the compression mechanism 4 to avoid dust mixing with the metal sheet and reduce the possibility of polluting the dust-free workshop. Under the action of the inert powder adding mechanism 3, inert dust is mixed in the dust-containing airflow, which can increase the minimum ignition energy of the mixed metal dust to reduce the risk of explosion and improve the safety of on-site work. At the same time, the high degree of automation can reduce human resource costs.

[0049] It should be noted that inert dust refers to dust that is not easy to burn or explode. This type of dust is usually composed of metal, lime, fly ash, silicate and other substances. The addition of inert dust can reduce the flammability and explosiveness of dust. Inert dust can absorb heat, lower the system temperature, and dilute the oxygen concentration, making it difficult for dust particles to form a combustible mixture.

[0050] Among them, Figure 2 and Figure 5As shown, the inert powder adding mechanism 3 includes a connecting pipe 31, an air pump 32 and an inert powder storage device (not shown in the figure), the connecting pipe 31 is connected and communicated with the separation mechanism 1 and the filtering mechanism 2, the air pump 32 is communicated with the connecting pipe 31 and the inert powder storage device, and the inert powder storage device is filled with inert powder. The connecting pipe 31 is provided to provide a communication channel for the separation mechanism 1 and the filtering mechanism 2, so that the inert powder storage device can mix the inert dust with the dust-containing gas before it enters the filtering mechanism 2 under the action of the air pump 32, thereby reducing the risk of explosion, and a wind speed sensor is provided inside the connecting pipe 31 to monitor and control the wind speed of the pipeline, requiring the wind speed in the pipeline to be above the required wind speed to prevent dust accumulation.

[0051] In addition, if Figure 2 and Figure 3 As shown, the separation mechanism 1 includes a separation chamber 11, in which a first screen plate 12 is arranged, and the first screen plate 12 is used to filter metal thin materials. The separation chamber 11 is divided into an upper air filter area 13 and a lower buffer area 14 through the first screen plate 12, and the upper air filter area 13 is connected to the filtering mechanism 2, and the lower buffer area 14 is connected to the compression mechanism 4. The separation chamber 11 is provided with an air inlet 15, and the air inlet 15 is located in the lower buffer area 14. The first screen plate 12 is provided with a first pulse backflush device 16, and the first pulse backflush device 16 is used to remove the metal thin materials accumulated below the first screen plate 12. The metal thin material is blown to the compression mechanism 4. Since the air inlet 15 is arranged at the lower buffer zone 14, when the external dust and the metal thin material enter the separation chamber 11 with the air flow, the air flow passes through the first screen plate 12 upward according to the guiding direction and enters the upper filter area 13, and then enters the filtering mechanism 2. At this time, the metal thin material is accumulated under the screen plate under the interaction of the air flow and the first screen plate 12. After the metal thin material accumulates to a certain amount, the pulse backblowing device is started, so that the accumulated metal thin material is blown to the compression mechanism 4 for the compression process, thereby realizing the separation of the dust-containing gas and the metal thin material.

[0052] Furthermore, the lower buffer 14 is connected to the filter mechanism 2 and a second screen plate 17 is provided at the connection point of the lower buffer 14. The second screen plate 17 is used to filter thin metal materials. A connection point connected to the filter mechanism 2 is provided in the lower buffer 14, so that part of the escaped dust affected by gravity can enter the filter mechanism 2 from the lower buffer 14 along with the airflow, thereby improving the filtration efficiency. In addition, by providing the second screen plate 17, the passage of thin metal materials can be effectively prevented, and at the same time, under the action of the pulse backblowing device, the high-pressure pulse airflow enters the compression mechanism 4 for the compression process.

[0053] It should be noted that the first screen plate 12 and the second screen plate 17 can select screens with various apertures for separation, and the size of the dust entering the filtering mechanism 2 can be controlled by controlling the size of the apertures of the screens.

[0054] Furthermore, the lower buffer zone 14 is provided with an upper valve 7 and a lower valve 8, the upper valve 7 is provided between the air inlet 15 and the second screen plate 17, the lower valve 8 is provided between the second screen plate 17 and the compression mechanism 4, and the upper valve 7 and the lower valve 8 are both used to support the metal thin material. By providing the upper valve 7 and the lower valve 8 in the lower buffer zone 14, the falling metal thin material can be gradually dropped into the compression mechanism 4, that is, when the metal thin material accumulated in the lower buffer zone 14 is small, the upper valve 7 is opened and the lower valve 8 is closed, so that the first screen plate 12 and the second screen plate 17 simultaneously block and screen the metal thin material, and the metal thin material is accumulated at the lower valve 8. After running for a period of time, the upper valve 7 is closed and the lower valve 8 is opened. At this time, the metal thin material accumulates into a metal pile of a certain weight, which can naturally fall into the compression mechanism 4, and the metal thin material can be prevented from flowing back to the upper valve 7.

[0055] In addition, if Figure 2 and Figure 4 As shown, the filter mechanism 2 includes a filter chamber 21, and a primary filter device 22, a secondary filter device 23 and a dust container 24 are arranged inside the filter chamber 21. The dust-laden airflow passes through the primary filter device 22 and the secondary filter device 23 in the filter chamber 21 in sequence. The primary filter device 22 is used to filter the dust-laden airflow and transport the dust to the dust container 24, and the secondary filter device 23 is used for secondary filtration. By arranging the primary filter device 22 and the secondary filter device, secondary filtration of the dust-laden airflow can be achieved, which is convenient for the staff to control the cleanliness of the air discharged outside the equipment by controlling the filtration accuracy of the filter material used, and by arranging the dust container 24, the dust can be collected while the filtration is completed.

[0056] Specifically, the primary filtering device 22 includes a mounting plate 221, and a plurality of filter cartridges 222 are provided on the mounting plate 221. The filter cartridges 222 are used to filter dust. A second pulse back-blowing device 223 is provided between the mounting plate 221 and the secondary filtering device. The second pulse back-blowing device 223 is used to transport the dust accumulated on the surface of the filter cartridge 222 to the dust container 24. By providing a plurality of filter cartridges 222, the dust-containing airflow can be initially filtered in large quantities. When the thickness of the dust layer on the surface of the filter cartridge 222 reaches a level that affects the filtering performance of the filter cartridge 222, the second pulse back-blowing device 223 can be started to transport the dust accumulated on the surface of the filter cartridge 222 to the dust container 24 through a high-pressure pulse airflow.

[0057] It should be noted that the structural principles of the above-mentioned first pulse back-blow device 16 and the second pulse back-blow device 223 are the same. They are existing technical equipment and can be obtained through procurement. They are mainly composed of a pneumatic system and a control system. Their working principle is to generate impact force and shear force through high-pressure gas pulse jet to knock down dust and dirt on the filter or screen. This is common knowledge among technicians in this field and will not be elaborated here.

[0058] Specifically, the secondary filtering device 23 is a high-efficiency filter, which can capture dust particles larger than 0.5 um and various suspended matter, and is suitable for secondary filtering conditions.

[0059] It should also be noted that the power air source 5 mainly includes a fan power unit and an internal flow field channel of the chassis 6. The fan power unit can provide air volume and negative pressure for the entire machine and the pipeline system connected to the machine, generate power in the system, guide dust and thin metal to move in the flow field channel, and bring them from the pipeline system into the chassis 6. Its structure and principle are common knowledge known to technicians in this field and will not be elaborated here.

[0060] In this embodiment, if Figure 6 and Figure 7 As shown, the compression mechanism 4 includes a compression box 41, a compression plate 42, an electric pressure cylinder 43 and a waste collection box 44. The top of the compression box 41 is connected to the separation mechanism 1 and is used to collect metal thin materials. One side of the compression box 41 is open and connected to the waste collection box 44. An electric valve 45 is provided at the connection between the compression box 41 and the waste collection box 44. The compression plate 42 is fixedly mounted on the push rod of the electric pressure cylinder 43. The electric pressure cylinder 43 is arranged in the compression box 41. When the electric valve 45 is closed, the electric pressure cylinder 43 is used to drive the compression plate 42 to move close to the electric valve 45. When compression is performed, after the metal thin materials are transported from the separation mechanism 1 to the compression box 41 and piled up into a metal pile, the electric pressure cylinder 43 is started to drive the push rod to drive the compression plate 42 to push the metal pile to move until it abuts against the electric valve 45 to complete the extrusion of the metal pile. Then, the electric valve 45 is opened so that the extruded metal pile can enter the waste collection box 44 to complete the collection, thereby increasing the collection amount of metal waste, reducing the interval of manual collection, and thus saving human resource costs.

[0061] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
