Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a dust collector for electrical automation production. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter bags, the dust is trapped, thus purifying the gas.

[0003] Existing baghouse dust collectors often suffer from filter bag damage and combustion when filtering dust due to the large impact force or high temperature of the gas entering the machine. This results in a significant decrease in the dust removal quality of the dust collector. Therefore, in order to solve the above problems, a dust collector for electrical automation production is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dust collector for electrical automation production, which aims to improve the problem that the filter bags of existing bag dust collectors are easily damaged, resulting in a decline in dust removal quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust collector for electrical automation production includes a cylindrical shell. The interior of the cylindrical shell is divided into a dust filtering chamber and an air outlet chamber by a partition. A reinforced filter bag for dust filtering is installed on the bottom side of the partition to reduce the impact of air entering the dust filtering chamber while filtering dust. A second air pipe is fixedly connected inside the air outlet chamber. A nozzle for air jetting is installed on the bottom side of the second air pipe. High-pressure gas is provided through an air outlet assembly installed on the outer wall of the cylindrical shell to impact the interior of the reinforced filter bag through the nozzle, shaking off the dust on the surface of the reinforced filter bag. The shaken-off dust falls into the bottom of the interior of the dust filtering chamber and is discharged by a dust removal assembly. The inlet end of the cylindrical shell is connected to a cooling chamber through an air supply pipe. The cooling chamber preferentially sprays and cools the high-temperature dusty exhaust gas entering the cylindrical shell, reducing the intensity of subsequent dust removal work.

[0007] As a further description of the above technical solution, the reinforced filter bag includes multiple fixing frames fixedly connected to the bottom side of the partition plate, the filter bag is disposed inside the fixing frame, and the filter bag is supported by a support member inside the filter bag.

[0008] As a further description of the above technical solution, the air outlet assembly includes a pulse air bag fixedly connected to the outer wall of the cylindrical shell, a pulse solenoid valve is installed at the output end of the second air pipe, and the pulse air bag and the pulse solenoid valve are connected through a first air pipe.

[0009] As a further description of the above technical solution, the ash discharge assembly includes an ash hopper fixedly connected to the bottom side of the cylindrical shell, an ash discharge port fixedly connected to the bottom side of the ash hopper, an ash discharge wheel rotatably connected inside the ash discharge port, the ash discharge wheel being driven to rotate by a motor, and the motor being mounted on the outer wall of the ash discharge port via a mounting bracket.

[0010] As a further description of the above technical solution, the cooling chamber includes a spray box located on the front side of the cylindrical shell.

[0011] As a further description of the above technical solution, the input end of the water pump is fixedly connected to an external pipe, and the bottom right side of the spray box is fixedly connected to a drain port.

[0012] As a further description of the above technical solution, an air outlet is fixedly connected to the right side of the cylindrical outer shell, a filter plate is fixedly connected to the inner wall of the air outlet, and an air inlet is fixedly connected to the front side of the spray box.

[0013] As a further description of the above technical solution, the bottom end of the outer wall of the cylindrical shell is supported by a metal bracket.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1-7 One embodiment provided by this utility model:

[0028] A dust collector for electrical automation production includes a cylindrical shell 1. The interior of the cylindrical shell 1 is divided into a dust filtering chamber and an air outlet chamber by a partition 10. A reinforced filter bag for dust filtering is installed on the bottom side of the partition 10 to reduce the impact of air entering the dust filtering chamber while filtering dust. A second air pipe 17 is fixedly connected inside the air outlet chamber. A nozzle 18 for air jetting is installed on the bottom side of the second air pipe 17. High-pressure gas is provided through the air outlet assembly installed on the outer wall of the cylindrical shell 1 to impact the interior of the reinforced filter bag through the nozzle 18, shaking off the dust on the surface of the reinforced filter bag. The shaken-off dust falls into the bottom side of the interior of the dust filtering chamber and is discharged by the dust discharge assembly. The inlet end of the cylindrical shell 1 is connected to a cooling chamber through an air supply pipe 2. The cooling chamber prioritizes the high-temperature dusty exhaust gas entering the interior of the cylindrical shell 1 for primary spray dust removal and cooling, reducing the intensity of subsequent dust removal work. The bottom end of the outer wall of the cylindrical shell 1 is supported by a metal bracket 23.

[0029] The reinforced filter bag consists of multiple fixed frames 11 fixedly connected to the bottom side of the partition plate 10, filter bags 12 are arranged inside the fixed frames 11, and support members 13 for supporting the filter bags 12 are arranged inside the filter bags 12. The filter bags 12 are made of polyester fiber non-woven fabric and are hollow inside. They can capture fine particles in the air while ensuring that the airflow is not obstructed, thereby achieving the effect of filtering and removing dust.

[0030] The gas outlet assembly includes a pulse gas chamber 14 fixedly connected to the outer wall of the cylindrical shell 1. The pulse gas chamber 14 stores compressed gas. A pulse solenoid valve 16 is installed at the output end of the second air pipe 17. The pulse gas chamber 14 and the pulse solenoid valve 16 are connected through a first air pipe 15. The working principle of the pulse solenoid valve 16 is as follows: the device is based on the action of electromagnetic force. When the electromagnet is energized, a magnetic field is generated. The magnetic field acts on the magnetic conductor on the iron core, attracting the magnetic conductor to the electromagnet. The magnetic conductor drives the power mechanism to achieve the purpose of opening and closing the valve. The pulse solenoid valve 16 mainly consists of an iron core, a coil with a wrapped winding, and a valve. In vacuum, air pressure, and other working conditions, control is achieved by opening and closing the valve. After the pulse solenoid valve 16 is opened, the compressed air in the pulse air bag 14 passes through the first air pipe 15 and then through the pulse solenoid valve 16, and through multiple nozzles 18 installed on the bottom side of the second air pipe 17 to spray a high-speed, high-pressure jet airflow onto the filter bag 12 at the corresponding position on the bottom side. This forms an induced defect flow equivalent to 1 to 2 times the volume of the jet airflow, causing an instantaneous positive pressure inside the filter bag 12 and generating expansion and micro-movement, thereby causing the dust deposited on the filter bag 12 to fall off.

[0031] The ash discharge assembly includes an ash hopper 19 fixedly connected to the bottom side of the cylindrical shell 1. An ash discharge port 20 is fixedly connected to the bottom side of the ash hopper 19. An ash discharge wheel 21 is rotatably connected inside the ash discharge port 20. The ash discharge wheel 21 is driven to rotate by a motor 22. The motor 22 is mounted on the outer wall of the ash discharge port 20 through a mounting bracket. The dust in the ash hopper 19 slides towards the ash discharge wheel 21 by gravity. The ash discharge wheel 21 discharges the dust from the ash discharge port 20 through the rotation of the drive end of the motor 22.

[0032] The cooling chamber includes a spray box 3 located at the front of the cylindrical outer shell 1. One end of the air supply duct 2 is fixedly connected to the top of the spray box 3, and the other end of the air supply duct 2 is fixedly connected to the bottom of the front of the cylindrical outer shell 1. A housing 4 is fixedly connected to the left side of the spray box 3. A water pump 5 is installed inside the housing 4. A water pipe 6 is fixedly connected to the output end of the water pump 5. The right end of the water pipe 6 penetrates the inner wall of the spray head 7, and multiple spray heads 7 for spraying are fixedly connected to the outer wall of the right end of the water pipe 6. An external pipe 9 is fixedly connected to the input end of the water pump 5. The right side of the spray box 3... A drain port 8 is fixedly connected to the bottom side. The spray head 7 can spray water mist to increase the contact area with the introduced exhaust gas, thereby enhancing the cooling effect. When performing the gas cooling step, water is first introduced through the external pipe 9 at the input end of the water pump 5 and then transported to the water pipe 6 connected to the output end. The spray head 7 sprays the water in the water pipe 6 in the spray box 3 in the form of water mist to cool the gas and at the same time remove some dust from the gas, improving the efficiency of the machine's dust removal. The water after cooling and dust removal will fall into the bottom side of the spray box 3 and be discharged through the drain port 8.

[0033] An air outlet 24 is fixedly connected to the right side of the cylindrical outer shell 1. A filter plate 25 is fixedly connected to the inner wall of the air outlet 24. An air inlet 26 is fixedly connected to the front side of the spray box 3. The filter plate 25 is made of activated carbon. The gas that has been filtered by the filter bag 12 is discharged through the air outlet 24. It will be filtered again by the filter plate 25 along the way, thereby improving the air quality filtered by the machine.

[0034] An observation window is provided at the bottom rear side of the outer wall of the cylindrical outer shell 1 for observing the working conditions inside the machine. The observation window is supported by tempered glass to prevent breakage caused by excessive air pressure inside the machine.

[0035] Working principle: First, connect the pipeline carrying the gas to be dusted to the air inlet 26. Then start the machine. The dust-filled gas enters the spray box 3 through the air inlet 26 for gas cooling. Water is introduced into the water pump 5 through the external pipe 9 and delivered to the water pipe 6 connected to the output end. The spray head 7 sprays the water in the water pipe 6 into the spray box 3 in the form of water mist to cool the gas and remove some of the dust, improving the efficiency of the machine's dust removal. The cooled water falls to the bottom of the spray box 3 and is discharged through the drain port 8, completing the cooling process. The gas enters the cylindrical outer shell 1 through the air supply duct 2. The gas is filtered through the filter bag 12. The clean gas that passes through the filter bag 12 is discharged through the inside of the filter bag 12. Dust will accumulate on the outer surface of the filter bag 12. By installing the support member 13 inside the filter bag 12 when installing the filter bag 12, the structure of the filter bag 12 can be further supported on the inner wall on the basis of the fixing frame 11 on the outer wall of the filter bag 12, so as to prevent the filter bag 12 from being damaged by impact. The gas filtered by the filter bag 12 is discharged through the air outlet 24. It will be filtered again by the filter plate 25 along the way to complete the dust removal filtration.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
