Description

Technical Field

[0001] This utility model relates to a hazardous waste treatment and recycling device for lead-strengthened smelting, belonging to the field of hazardous waste recycling technology in metal smelting. Background Technology

[0002] Lead strengthening smelting is an important step in the lead smelting process, aiming to improve smelting efficiency, reduce energy consumption, and optimize product quality.

[0003] Fuming furnaces are mainly used to process lead blast furnace slag. By blowing a mixture of air and pulverized coal into the liquid slag, some valuable metals in the slag, such as lead and zinc, are volatilized in the form of metals, oxides or sulfides. These volatilized metals and their compounds are then collected and further processed, thereby improving the metal recovery rate.

[0004] Baghouse dust collectors, which are commonly used in conjunction with fuming furnaces, can filter and recover metals from the gas. However, the filter bags in most baghouse dust collectors on the market lack a limiting structure during installation, which makes them prone to slipping into the baghouse dust collector and further affecting installation efficiency.

[0005] Therefore, it is urgent to improve the hazardous waste treatment and recycling equipment for lead-strengthened smelting in order to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a hazardous waste treatment and recycling device for lead strengthening smelting. By using a limiting ring and a limiting block to restrict one end of the dust collector filter bag, it not only prevents the dust collector filter bag from falling into the bag filter due to operational errors during installation, but also facilitates the subsequent installation of the filter bag frame by the staff.

[0007] To achieve the above objectives, the main technical solution adopted by this utility model includes: a bag filter and a recycling bin disposed on one side of the bag filter. A partition is fixedly installed on the upper half of the bag filter. Several mounting slots are provided on the partition. A dust filter bag for filtering waste residue is installed inside each mounting slot. Several limiting slots located on opposite sides of the mounting slots are also provided on the partition. An air inlet chamber is fixedly installed on one side of the bag filter, and the interior of the air inlet chamber is connected to the interior of the bag filter. A baffle plate is fixedly installed at the connection between the air inlet chamber and the bag filter.

[0008] Preferably, each of the dust collector filter bags is fixedly provided with a limiting ring at its upper end, and limiting blocks are fixedly connected to both sides of the limiting ring. The size and number of the limiting blocks are the same as those of the limiting groove.

[0009] Preferably, a through groove for connecting to a delivery pipe is provided on one side of the air inlet cavity, and an air bag is fixedly installed at the upper end of the air inlet cavity.

[0010] Preferably, a plurality of blowpipes are fixedly installed on one side of the air tank. The number of rows of the blowpipes is the same as that of the mounting groove, and all of them are located directly above the mounting groove. Each blowpipe has a nozzle fixedly installed on the side near the dust collector filter bag.

[0011] Preferably, an upper chamber is provided between the partition and the bag filter, and an air outlet connection groove is provided on the side of the bag filter away from the air inlet chamber. The air outlet connection groove is connected to the upper chamber and is used for the discharge of gas.

[0012] Preferably, the lower end of the bag filter is fixed and connected to a discharge valve. A conveying pipe is fixedly installed at the end of the discharge valve away from the bag filter. The other end of the conveying pipe is fixedly connected to the recycling bin. The conveying pipe is used to transport waste material from 1 to the inside of 8.

[0013] Preferably, both the bag filter and the lower half of the recycling bin are fixedly installed with a first support frame and a second support frame to ensure that the two are at the same height.

[0014] This utility model has at least the following beneficial effects: One end of the dust collector filter bag can be restricted by a limiting ring and a limiting block. Then, the operator can manually rotate the limiting ring so that the limiting block can connect with the limiting groove. This not only prevents the dust collector filter bag from falling into the bag filter due to operational errors during installation, but also makes it easier for the operator to install the filter bag frame afterwards.

[0015] The air inlet chamber can be connected to the fuming furnace through a conveying pipe, allowing metal-containing gas to enter the interior of the bag filter. At the same time, baffles can be used to prevent the gas entering the bag filter from directly impacting the filter bags. Attached Figure Description

[0018] like Figures 1-4 As shown, a hazardous waste treatment and recycling device for lead strengthening smelting includes: a bag filter 1 and a recycling bin 8 disposed on one side of the bag filter 1. A partition 11 is fixedly installed on the upper half of the bag filter 1. The partition 11 has several mounting slots 19. Each mounting slot 19 is equipped with a dust collection filter bag 14 for filtering waste residue. The partition 11 also has several limiting slots 18 located on opposite sides of the mounting slots 19. Each dust collection filter bag 14 has a limiting ring 16 fixedly installed at its upper end. The limiting rings 16 are located on opposite sides of the limiting rings 18. Each partition 11 is fixedly connected with a limiting block 17, the size and number of which are the same as the limiting groove 18. Multiple mounting grooves 19 are provided on the partition 11 to facilitate the placement of the dust collector filter bag 14 inside the baghouse dust collector 1, thereby adsorbing and filtering metal materials contained in the gas. Limiting grooves 18 are provided on both sides of the mounting groove 19, which can be used in conjunction with the limiting blocks 17 to prevent the dust collector filter bag 14 from falling into the baghouse dust collector 1 after being removed from the worker's hand during installation. During installation, the operator first places the dust collector filter bag 14 into the baghouse dust collector 1 through the installation slot 19. Then, the operator can use the limiting ring 16 and the limiting block 17 to restrict one end of the dust collector filter bag 14. The operator then manually rotates the limiting ring 16 so that the limiting block 17 can connect with the limiting slot 18. This not only prevents the dust collector filter bag 14 from falling into the baghouse dust collector 1 due to operational errors during installation, but also facilitates the subsequent installation of the filter bag frame. An air inlet chamber 2 is fixedly installed on one side of the bag filter 1. The interior of the air inlet chamber 2 is connected to the interior of the bag filter 1. A baffle plate 15 is fixedly installed at the connection between the air inlet chamber 2 and the bag filter 1. A through groove is opened on one side of the air inlet chamber 2 for connecting to the conveying pipe. The air inlet chamber 2 can be connected to the fuming furnace through the conveying pipe, so that the gas containing metal can enter the interior of the bag filter 1. At the same time, the baffle plate 15 can prevent the gas entering the bag filter 1 from directly impacting the dust filter bag 14.

[0019] Furthermore, such as Figure 1 , Figure 3 As shown, an air tank 3 is fixedly installed at the upper end of the air inlet chamber 2. Several blow pipes 13 are fixedly installed on one side of the air tank 3. The number of rows of blow pipes 13 is the same as that of the mounting groove 19, and they are all located directly above the mounting groove 19. Each blow pipe 13 has a nozzle fixedly installed on the side near the dust collector filter bag 14. By opening the air tank 3, the air tank 3 can use the blow pipes 13 and nozzles to spray air into the dust collector filter bag 14, so that the metal material attached to the outside of the dust collector filter bag 14 can be cleaned and fall off for recycling.

[0020] Furthermore, such as Figure 3 , Figure 4 As shown, an upper chamber 12 is provided between the partition 11 and the bag filter 1. An air outlet connection slot 5 is provided on the side of the bag filter 1 away from the air inlet chamber 2. The air outlet connection slot 5 is connected to the upper chamber 12 and is used for gas discharge. An air supply pipe can be added to the air outlet connection slot 5 so that the air filtered inside the bag filter 1 can be discharged or reused. The air outlet connection slot 5 is located in the upper part of the bag filter 1 and is connected to the upper chamber 12, thereby preventing the air containing metal materials from being extracted when the air inside the bag filter 1 is extracted.

[0021] Furthermore, such as Figure 1 As shown, the lower end of the bag filter 1 is fixed and connected to the discharge valve 6. The end of the discharge valve 6 away from the bag filter 1 is fixedly installed with a conveying pipe 7. The other end of the conveying pipe 7 is fixedly connected to the recycling bin 8. The conveying pipe 7 is used to transport waste material from the bag filter 1 to the inside of the recycling bin 8. When conveying metal material inside the bag filter 1 to the recycling bin 8, the discharge valve 6 can be activated to avoid excessive metal material accumulating in one place, which would cause the discharge speed to be slow. The lower half of the bag filter 1 and the recovery bin 8 are both fixedly installed with a first support frame 4 and a second support frame 10 to ensure that the two are at the same height. The height of the bag filter 1 and the recycling bin 8 can be raised by the first support frame 4 and the second support frame 10, so that the unloading valve 6 can be installed at the outlet end of the bag filter 1, and the recycling bin 8 can be used to place recycling boxes and other items for recycling metal materials.

[0022] In this embodiment, as Figures 1-4 As shown in this embodiment, the principle of a hazardous waste treatment and recycling device for lead strengthening smelting is as follows: First, the operator places the dust collector filter bag 14 into the baghouse dust collector 1 through the installation slot 19. Then, the operator uses the limiting ring 16 and the limiting block 17 to restrict one end of the dust collector filter bag 14. The operator then manually rotates the limiting ring 16 so that the limiting block 17 can connect with the limiting slot 18. This not only prevents the dust collector filter bag 14 from falling into the baghouse dust collector 1 due to operational errors during installation, but also facilitates the subsequent installation of the filter bag frame. Furthermore, the air inlet chamber 2 can be connected to the fumigation furnace through the conveying pipe, allowing metal-containing gas to enter the baghouse dust collector 1. At the same time, the baffle plate 15 can prevent the gas entering the baghouse dust collector 1 from directly impacting the dust collector filter bag 14.
