Description

Technical Field

[0001] The present application relates to the technical field of air intake devices, and in particular to an air intake device for a bag dust collector. Background Art

[0002] A bag dust collector is a dry dust filtering device, which is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of the fiber fabric to filter the dust-containing gas. The bag dust collector structure includes an air intake device for air intake.

[0003] At present, the relevant air intake device lacks a filter bag structure that can be quickly disassembled and assembled. When the filter bag needs to be disassembled and replaced, multiple disassembly tools are needed. The replacement operation is cumbersome, affecting work efficiency, and the gas enters the direct-blowing filter bag, which is easy to damage the filter bag. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the present application provides an air intake device for a bag dust collector.

[0005] The air intake device of a bag dust collector provided in the present application adopts the following technical solution:

[0006] A bag dust collector has an air intake device, comprising an air outlet pipe, a shell and a filter bag, wherein an air intake pipe is fixedly connected to the surface of one side of the shell, an air guide pipe is fixedly connected to the inside of the shell on one side of the air intake pipe, a flow rate control valve is fixedly connected to the periphery of the air guide pipe, a connecting ring is fixedly connected to the top of the air guide pipe, a supporting ring is fixedly connected to the periphery of the connecting ring, a positioning bolt is movably installed on one side of the support ring, support blocks are fixedly connected to both sides of the shell, a filter bag is movably installed on the top of the support block, a fixing ring is fixedly connected to the bottom of the filter bag, and the fixing ring is embedded with the support ring.

[0007] By connecting the device to an external bag dust collector structure and by connecting an external exhaust device to the device, the gas enters the interior of the air duct through the air inlet pipe, and is then introduced into the interior of the filter bag through the air duct. The gas is filtered by the filter bag and discharged from the device from the air outlet pipe after filtration. The air duct can prevent the gas from directly blowing into the filter bag. The flow rate control can control the flow rate of the gas to prevent the filter bag from being damaged by a fast gas flow rate. When the staff needs to disassemble and replace the filter bag, they can quickly disassemble the filter bag by loosening the positioning bolt and then lifting the filter bag upward. When installing a new filter bag, place the filter bag on the top of the support block so that the connecting ring is engaged with the fixing ring and the fixing ring is engaged with the support ring, so that the filter bag can be quickly replaced.

[0008] Preferably, a flange is fixedly connected to the top of the air outlet pipe and one side of the air inlet pipe, and a bolt hole is provided inside the flange.

[0009] The gas inlet and outlet structures are connected to the flange, and then external fixing bolts are screwed between the gas inlet and outlet structures and the flange and penetrate through the bolt holes, so that the gas inlet and outlet structures are fixed to the flange.

[0010] Preferably, a sealing door is movably installed on the top of the shell surface, and a handle is fixedly connected to the surface of the sealing door.

[0011] The filter bag can be disassembled and maintained by opening the sealed door by pulling the handle.

[0012] Preferably, a maintenance door is movably installed at the bottom of the shell surface, and bolts are movably installed between the maintenance door and the shell.

[0013] The flow control valve can be maintained by unscrewing the bolts and then pulling the maintenance door off.

[0014] Preferably, both sides of the bottom of the shell are fixedly connected with support rods, and the side close to the support rods is fixedly connected with a fixing rod.

[0015] The support is formed between the support rod and the ground, and the support rod is connected by a fixing rod to enhance the stability of the support rod.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] By setting up the air duct, it is possible to prevent gas from directly blowing into the filter bag. The flow rate control valve can control the flow rate of gas to prevent the filter bag from being damaged by a fast gas flow rate, thereby effectively protecting the filter bag. The filter bag can be quickly disassembled by loosening the positioning bolt and then lifting the filter bag upward. When installing a new filter bag, place the filter bag on the top of the support block so that the connecting ring is engaged with the fixing ring, and the fixing ring is engaged with the support ring at the same time, so that the filter bag can be quickly replaced, which is convenient for the staff to quickly replace the filter bag without using multiple disassembly tools, saving manpower and time, and improving maintenance efficiency.
