Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and in particular to a bag filter for dye production. Background Technology

[0002] A baghouse dust collector for dye production is a dry filtration device used in the dye production process to capture dust and particulate matter. It is primarily used for efficient air purification, ensuring production safety, preventing excessive dust accumulation that could lead to explosions and other safety accidents, and protecting employee health. The reason for using a baghouse dust collector in dye production is that the dye production process generates a large amount of industrial fumes containing various metal and non-metal fine particles, as well as harmful gases such as sulfur dioxide, nitrogen oxides, and hydrocarbons. These dust particles typically have a diameter of less than 0.19 mm, are in irregular Brownian motion, and some of the fumes may be highly flammable and explosive. Ordinary dust collection equipment is difficult to effectively handle this type of fumes, while a baghouse dust collector can filter the dust-laden gas through its filter bags, trapping dust particles on the surface of the filter bags, allowing the filtered clean gas to be discharged.

[0003] The structure of a baghouse dust collector generally consists of a housing, a dust hopper, a dust removal system, and a dust discharge mechanism. Typically, dust-laden gas enters the dust collector through the inlet. Under the action of the gas flow rate, most of the dust and particulate matter are captured by the filter bags, and clean air is discharged through the outer surface of the filter bags. Then, the dust removal system uses electromagnetic pulses to blow high-speed air toward the filter bags, causing the dust to fall off the surface of the filter bags.

[0004] In existing baghouse dust collectors used in dye production, the dust collection filter bags and the dust collection box are installed as a single unit. Over time, dust will gradually accumulate on the surface of the filter bags. Although there is a dust removal system, it is still difficult to completely avoid dust residue. Moreover, the filter bags will inevitably age over time. The single-unit installation is not conducive to the replacement of filter bags, resulting in longer downtime and thus affecting the efficiency of dye production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bag filter dust collector for dye production, which aims to improve the problem in the prior art where the dust collector filter bag and dust collector box are installed as a whole, which is not conducive to filter bag replacement and thus leads to long downtime and affects dye production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a baghouse dust collector for dye production, comprising a dust collection box, a dust collection filter bag disposed inside the dust collection box, an installation frame disposed inside the dust collection box, one side of the outer wall of the dust collection filter bag being attached to the lower surface of the installation frame, an installation cylinder being fixedly connected inside the installation frame, one side of the outer wall of the installation cylinder being slidably connected to the inside of the dust collection box, a baffle being fixedly connected inside the installation cylinder, and a snap-fit ​​assembly for installing the installation frame inside the dust collection box being installed inside the installation cylinder; a bolt being threadedly connected inside the installation cylinder, and a connecting assembly for easy disassembly being installed on the lower surface of the bolt; the snap-fit ​​assembly comprising a snap block, one side of the outer wall of the snap block being slidably connected to the inside of the installation cylinder, and a spring disposed inside the installation cylinder, one end of the spring being fixedly connected to one side of the outer wall of the snap block.

[0007] Furthermore, the connecting assembly includes a connecting frame, the upper surface of which is fixedly connected to the lower surface of the bolt, a connecting shaft is fixedly connected inside the connecting frame, a connecting rod is rotatably connected to one side of the outer wall of the connecting shaft, one side of the outer wall of the connecting rod is in contact with one side of the outer wall of the baffle, and one side of the outer wall of the connecting rod is in contact with one side of the outer wall of the locking block.

[0008] Furthermore, a heat-conducting box is fixedly connected inside the dust removal box, and a water inlet pipe is fixedly connected inside the heat-conducting box.

[0009] Furthermore, a water outlet pipe is fixedly connected inside the heat conduction box, and a support frame is fixedly connected to the lower surface of the dust removal box.

[0010] Furthermore, a dust hopper is fixedly connected to the lower surface of the dust collection box, and a water pump is installed adjacent to one side of the outer wall of the support frame.

[0011] Furthermore, a water tank is fixedly connected to the input end of the water pump, and the output end of the water pump is fixedly connected to one end of the inlet pipe.

[0012] Furthermore, an electromagnetic pulse blowing pipe is fixedly connected to one side of the outer wall of the dust collector, and an air outlet pipe is fixedly connected inside the dust collector.

[0013] Furthermore, an air inlet is fixedly connected inside the ash hopper, and the air inlet is used to introduce the gas generated during dye production.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the dust collector filter bag is pressed and fixed below by the mounting bracket. At the same time, the mounting cylinder passes through the filter bag, aligns it with the hole, and is snapped in place by the trapezoidal locking block, thus fixing the dust collector filter bag. The rotating bolt drives the connecting rod to rotate under the action of the baffle, which in turn drives the locking block to compress the spring, thereby achieving the effect of detachment from the dust collector box. This solves the problem in the prior art where the dust collector filter bag and the dust collector box are installed as a whole, which is not conducive to filter bag replacement and leads to long downtime, affecting dye production efficiency. This improves the practicality of the device.

[0016] 2. In this utility model, by setting up a water tank, a water pump carries the cooling water in the water tank into the heat conduction box. Due to its good heat conduction effect, the gas in the dust removal box is cooled. Then, the water flows back to the water tank through the water outlet pipe to realize water circulation. This solves the problems that some chemical reactions in the dye production process generate heat, which leads to excessively high temperature and damages the filter bag, as well as the problem that high-temperature dust is prone to explosion and endangers the safety of workers. This improves the practicality of the device. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a baghouse dust collector for dye production, comprising a dust collection box 1, providing a closed space for the dust collection process. A dust collection filter bag 7 is installed inside the dust collection box 1. The dust collection filter bag 7 is a key component for dust filtration, capable of capturing dust and particulate matter in dust-laden gas. A mounting frame 5 is installed inside the dust collection box 1. One side of the outer wall of the dust collection filter bag 7 is in contact with the lower surface of the mounting frame 5, ensuring close contact between the dust collection filter bag 7 and the mounting frame 5, which is beneficial for better dust collection. A mounting cylinder 9 is fixedly connected inside the mounting frame 5. One side of the outer wall of the mounting cylinder 9 is slidably connected inside the dust collection box 1. A baffle 11 is fixedly connected inside the mounting cylinder 9, limiting the movement range of the connecting rod 10 and ensuring that the connecting rod 10 can accurately drive the locking block 13 during rotation. A locking assembly for installing the mounting frame 5 inside the dust collection box 1 is installed inside the mounting cylinder 9. A bolt 8 is threadedly connected inside the mounting cylinder 9, and a connecting assembly for easy disassembly is installed on the lower surface of the bolt 8. The locking assembly includes a locking block 1. 3. The outer wall of the locking block 13 is slidably connected to the inside of the mounting cylinder 9. A spring 12 is installed inside the mounting cylinder 9. One end of the spring 12 is fixedly connected to the outer wall of the locking block 13. Under the elastic force of the spring 12, the locking block 13 can be locked into the slot inside the dust collector 1, thereby fixing the mounting bracket 5 inside the dust collector 1. When disassembly is required, the locking block 13 is disengaged from the slot by compressing the spring 12, thus disassembling the mounting bracket 5. The connecting component includes a connecting bracket 19, which connects the bolt 8 and the connecting rod 1. The function of 0 is that the upper surface of the connecting frame 19 is fixedly connected to the lower surface of the bolt 8, the connecting shaft 20 is fixedly connected inside the connecting frame 19, and the connecting rod 10 is rotatably connected to one side of the outer wall of the connecting shaft 20. Under the rotation of the bolt 8, the connecting rod 10 cooperates with the baffle 11 and the locking block 13 to realize the operation of the locking block 13 compressing the spring 12 and disengaging from the locking slot, thereby completing the disassembly of the mounting frame 5. One side of the outer wall of the connecting rod 10 is in contact with one side of the outer wall of the baffle 11, and one side of the outer wall of the connecting rod 10 is in contact with one side of the outer wall of the locking block 13.

[0025] Reference Figure 1 and Figure 4A heat-conducting box 18 is fixedly connected inside the dust collector housing 1. The heat-conducting box 18 is used to regulate the temperature inside the dust collector housing 1. It absorbs heat through internal coolant circulation to prevent the temperature inside the dust collector housing 1 from becoming too high due to heat generated during dye production, thereby protecting the filter bags and avoiding safety hazards caused by high temperatures. A water inlet pipe 16 is fixedly connected inside the heat-conducting box 18. The water inlet pipe 16 is used to transport coolant from the water tank 15 into the heat-conducting box 18, serving as the channel for coolant to enter the heat-conducting box 18. A water outlet pipe 14 is fixedly connected inside the heat-conducting box 18. The water outlet pipe 14 is used to return the coolant that has absorbed heat in the heat-conducting box 18 to the water tank 15, realizing the recycling of coolant and ensuring that there is always coolant in the heat-conducting box 18 for temperature regulation. A support frame 2 is fixedly connected to the lower surface of the dust collector housing 1. The support frame 2 serves to support the dust collector housing 1 and ensure that the dust collector housing 1... During operation, the dust collector 1 is fixedly connected to a dust hopper 3 on its lower surface. A water pump 17 is installed adjacent to one side of the outer wall of the support frame 2. The water pump 17 is used to draw coolant from the water tank 15 and deliver it to the water inlet pipe 16 to provide power for the circulation of coolant. The water tank 15 is fixedly connected to the input end of the water pump 17, and the output end of the water pump 17 is fixedly connected to one end of the water inlet pipe 16. An electromagnetic pulse blow pipe 4 is fixedly connected to one side of the outer wall of the dust collector 1. The electromagnetic pulse blow pipe 4 is used to spray a high-speed airflow onto the dust collector filter bag 7 during the dust removal process. When dust removal is required, the high-speed airflow generated by the electromagnetic pulse blow pipe 4 impacts the dust collector filter bag 7, causing the dust on the surface of the filter bag to fall off, maintaining the good air permeability of the filter bag, and ensuring dust removal efficiency. An air outlet pipe 6 is fixedly connected inside the dust collector 1, and an air inlet 21 is fixedly connected inside the dust hopper 3. The air inlet 21 is used to introduce the gas generated during dye production.

[0026] Working principle: The gas generated during dye production enters the dust collector 1 through the air inlet 21 inside the ash hopper 3. Under the action of the gas flow rate, most of the dust and particulate matter is captured by the dust collector filter bag 7. Clean air is discharged through the outer surface of the dust collector filter bag 7 and discharged to the outside through the air outlet 6 inside the dust collector 1. When installing the dust collector filter bag 7, place the dust collector filter bag 7 under the mounting frame 5 so that one side of the outer wall of the dust collector filter bag 7 is in contact with the lower surface of the mounting frame 5. One side of the outer wall of the mounting cylinder 9 is slidably connected to the inside of the dust collector 1. The locking block 13 inside the mounting cylinder 9 is in the extended state under the action of the spring 12. The mounting cylinder 9 is inserted through the filter bag and aligned with the hole. The locking block 13 is locked into the dust collector 1 under the elastic force of the spring 12, realizing the installation of the mounting frame 5 and the dust collector filter bag 7 inside the dust collector 1. When disassembling, rotate the bolt 8. The connecting frame 19, connecting shaft 20 and connecting rod 10 on the lower surface of the bolt 8 move accordingly, connecting... The rod 10 rotates under the action of the baffle 11, which in turn drives the locking block 13 to compress the spring 12, causing the locking block 13 to disengage from the slot of the dust collector 1, thereby achieving the effect of detaching the mounting bracket 5 and the dust collector filter bag 7 from the inside of the dust collector 1. When cooling the inside of the dust collector 1, the water pump 17 carries the cooling water in the water tank 15 into the heat conduction box 18 through the water inlet pipe 16. The heat conduction box 18 uses the good heat conduction effect of the cooling water to cool the gas inside the dust collector 1, preventing the temperature from getting too high due to the heat generated by the chemical reaction during the dye production process, avoiding damage to the filter bag, and preventing the high temperature dust from easily exploding and endangering the safety of workers. The cooled water flows back to the water tank 15 through the water outlet pipe 14 to achieve water circulation. When dust removal is required, the electromagnetic pulse blower 4 blows high-speed air towards the dust collector filter bag 7, causing the dust to fall off the surface of the dust collector filter bag 7, maintaining the good air permeability of the dust collector filter bag 7, and ensuring dust removal efficiency.
