Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a bag filter dust collector that is easy to disassemble and maintain. Background Technology

[0002] A baghouse dust collector is a high-efficiency dust removal device that uses woven fiber bags as a filter medium to capture solid particles in dust-laden gas. It is widely used in dust control in industries such as metallurgy, chemical industry, cement, power, and building materials. The basic structure of a baghouse dust collector typically includes a housing, a filter bag cage set inside the housing, filter bags installed on the cage, a pulse-jet cleaning system for dust removal, and a dust hopper. Dust-laden gas enters the housing through the inlet, where dust is trapped on the outer surface of the filter bags. The purified gas then passes through the filter bags into the upper housing and is discharged from the outlet.

[0003] Most existing devices cannot cool down the incoming high-temperature dust-laden gas. When the temperature of the dust-laden gas is too high, the high temperature will directly cause the filter bags to harden, shrink, or even burn out, which will greatly shorten the service life of the filter bags and increase the equipment maintenance cost and downtime risk.

[0004] Therefore, those skilled in the art have provided a bag filter device that is easy to disassemble and maintain in order to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bag filter dust collector that is easy to disassemble and maintain. Existing bag filters have a compact internal structure, and the installation and replacement of filter bags usually require operators to enter the narrow interior of the housing. This process is not only labor-intensive and time-consuming, but also creates a harsh working environment, posing a threat to the safety and health of the operators. This device simplifies the internal structure while ensuring functionality, allowing operators to disassemble and maintain the internal components simply by opening the movable door.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A bag filter dust collector that is easy to disassemble and maintain includes a dust collection frame. A cooling component is provided on one side of the dust collection frame. The cooling component includes a heat dissipation frame fixedly connected to the outer wall of one side of the dust collection frame. An air inlet pipe is provided inside the heat dissipation frame. Multiple heat dissipation fins are fixedly connected to the body of the air inlet pipe. A fixing frame is fixedly connected to the outer wall of the heat dissipation frame away from the dust collection frame. An installation frame is fixedly connected to the outer wall of the fixing frame away from the heat dissipation frame. A bracket is fixedly connected to the inner wall of the front end and the inner wall of the rear end of the installation frame. Multiple drive motors are fixedly connected to the inner wall of the brackets. Fan blades are fixedly connected to the output end of each drive motor. A sealing plate is fixedly connected to the upper end of the inner wall of the dust collection frame. Multiple dust collection filter bags are fixedly connected to the lower surface of the sealing plate. A blowpipe is provided at the upper end of the sealing plate. The above technical solution uses a cooling component to cool the dust-laden gas before it enters the filter bag, effectively protecting the bag from damage by the high-temperature gas, thus extending its lifespan and reducing maintenance frequency and costs.

[0007] Furthermore, one end of the air intake pipe passes through the heat dissipation frame to the upper part of the rear end of the heat dissipation frame, and the other end of the air intake pipe passes through the heat dissipation frame to the lower end of the dust removal frame. The above technical solution allows the copper intake pipe to effectively conduct the heat of the high-temperature dust-laden gas to the pipe body, and then heat the coolant and heat dissipation fins through the intake pipe. This increases the heat dissipation area through the heat dissipation fins, and together with the fan blades, it can effectively and quickly dissipate the heat of the high-temperature dust-laden gas.

[0008] Furthermore, a liquid injection valve pipe is fixedly connected to the front end of the upper surface of the heat dissipation frame, and a liquid drain valve pipe is fixedly connected to the rear end of the lower surface of the heat dissipation frame. Both the liquid injection valve pipe and the liquid drain valve pipe are in communication with the heat dissipation frame. The above technical solution allows for the effective replenishment of coolant to the interior of the heat sink via the injection valve pipe, and the effective replacement of coolant via the drain valve pipe.

[0009] Furthermore, a dust discharge valve hopper is fixedly connected to the lower surface of the dust removal frame, and support legs are fixedly connected to the four corners of the outer wall of the dust discharge valve hopper. The above technical solution effectively discharges the blown-out dust through the dust discharge valve, and the supporting legs effectively support the device.

[0010] Furthermore, a filter bag frame is fixedly connected to the lower surface of the dust collector filter bag, the outer wall of the filter bag frame is fixedly connected to the inner wall of the dust collector frame, and multiple exhaust grooves are opened on the upper surface of the sealing plate, the exhaust grooves are in communication with the interior of the dust collector filter bag. The above technical solution effectively fixes the lower ends of multiple dust collector filter bags by means of the filter bag frame, and the exhaust groove effectively allows the treated gas to enter the upper end of the dust collector frame from the lower end of the dust collector frame.

[0011] Furthermore, an exhaust pipe is fixedly connected to the center of the upper surface of the dust removal frame, and a movable door is hinged to one side of the outer wall at the front end of the dust removal frame. The above technical solution allows for the effective discharge of treated gas through the exhaust pipe, and the movable door facilitates the disassembly and maintenance of the device's internal components.

[0012] Furthermore, an air injection pipe is fixed through one side of the upper surface of the blowpipe, the air injection pipe extends to the upper end of the dust removal frame, and multiple blow holes are opened at the lower end of the blowpipe body. The above technical solution effectively connects the blowpipe to an external high-pressure gas pipeline through the air injection pipe, and the high-pressure gas can be pulsedly blown into the interior of the dust collector filter bag through multiple blow holes to remove dust from the filter bag.

[0013] Furthermore, a dust filter is fixedly connected to one side of the inner wall of the mounting frame; The above technical solution effectively filters dust from the inhaled air using a dust filter.

[0014] This utility model has the following beneficial effects: 1. The present invention proposes a bag filter device that is easy to disassemble and maintain. The cooling component efficiently absorbs the heat of high-temperature dust-laden gas through the coolant in the heat dissipation frame and the heat dissipation fins on the air inlet pipe. Combined with the fan blades driven by the drive motor to accelerate airflow, it achieves rapid heat dissipation. This effectively avoids the hardening, shrinkage or burning problems caused by the high-temperature gas directly contacting the dust filter bag, significantly extends the service life of the filter bag, and reduces maintenance costs and equipment downtime risks.

[0019] One end of the intake pipe 602 passes through the heat sink 601 to the upper part of the rear end of the heat sink 601, and the other end of the intake pipe 602 passes through the heat sink 601 to the lower end of the dust removal frame 1. The copper intake pipe 602 can effectively conduct the heat of the high-temperature dust-laden gas to the pipe body, and then heat the coolant and heat dissipation fins 604 through the intake pipe 602. This increases the heat dissipation area through the heat dissipation fins 604. Combined with the fan blades 608, it can effectively and quickly dissipate the high-temperature dust-laden gas.

The heat is transferred to the heat sink fins 604, and multiple drive motors 610 rotate multiple fan blades 608. These fan blades draw in external gas and deliver it to the fixed frame 603, accelerating the flow of heat to the heat sink fins 604. The airflow cools the high-temperature dust-laden gas. After cooling, the gas enters the dust collector frame 1 and passes through multiple dust filter bags 10 to remove dust. The gas then enters the upper part of the dust collector frame 1 through the exhaust chute 8 and is discharged through the exhaust pipe 4. After a period of use, high-pressure gas is injected into the air injection pipe 5 through the pulse pipe. The high-pressure gas then flows through the blow pipe 12 and removes dust from the dust filter bags 10 through the blow holes 7 of the blow pipe 12.
