Description

Technical Field

[0001] This utility model belongs to the technical field of pulse bag dust collectors, and in particular relates to an independent bag cleaning device. Background Technology

[0002] In metallurgical production, pulse jet baghouse dust collectors are crucial environmental protection equipment. They primarily filter dust and other pollutants generated during operation through filter bags. Specifically, the negative pressure generated by the dust collector fan draws dust and other pollutants through ducts into the dust collector housing. After being filtered by the orderly arranged filter bags within the housing, the gas that meets emission standards is discharged. The filter bags are the core component of the dust collector, used to filter dust; their operating conditions and lifespan directly affect the dust collector's efficiency.

[0003] The dust collector's built-in bag cleaning device primarily uses an electrical signal to control a pulse valve, outputting compressed gas from a pulse gas tank to create a jet-like gas impact force. This impact force travels through a jet pipe and is directed at the orderly arranged filter bags, causing the dust adhering to the bag's outer surface to fall into the ash hopper. One ash hopper corresponds to one set of filter bags, and the control valve controls one jet pipe, with each jet pipe connected to a set of filter bags. Filter bags are replaced during maintenance, but usually not all bags in the same set are replaced. During dust collector operation, uneven cleaning of the same set of filter bags can occur, affecting the lifespan of unreplaced bags. Therefore, a device capable of cleaning individual filter bags individually is needed. Summary of the Invention

[0004] The purpose of this invention is to provide an independent bag cleaning device that solves the problem of poor bag vibration effect, enables the cleaning of individual bags, reduces on-site dust, and saves time and effort.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The gas storage unit includes an air inlet pipe, a gas storage tank, and a pulse valve. The gas storage tank is connected to the air inlet pipe, and the gas storage tank is connected to the jet pipe via the pulse valve.

[0008] The intake pipe is connected to an intake control valve and a pressure gauge.

[0009] The blow-jet structure has foot pedals hinged to both sides.

[0010] The gas storage tank is equipped with a pressure sensor.

[0023] The present invention will now be described in detail with reference to the accompanying drawings. However, it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0024] See Figure 1 An independent bag cleaning device includes a hand-held mechanism, an air storage unit, a blow pipe 3, and a blow structure 13; the hand-held mechanism is connected to the air storage unit, the air storage unit is connected to the blow pipe 3, and the bottom end of the blow pipe 3 is connected to the blow structure 13.

[0025] The gas storage unit includes an inlet pipe 7, a gas storage tank 10, and a pulse valve 9. The gas storage tank 10 is connected to the inlet pipe 7, and the gas storage tank 10 is connected to the jet pipe 3 via the pulse valve 9. An inlet control valve 8 and a pressure gauge 6 are connected to the inlet pipe 7. A pressure sensor 11 is installed inside the gas storage tank 10 to detect the pressure inside the gas storage tank 10. The control valve 8 can be a one-way valve, and the pulse valve 9 can be a pulse solenoid valve.

[0026] The hand-held mechanism includes a hand-held rod 4 and a handle 5. The hand-held rod 4 is fixedly connected to the gas storage tank 10 of the gas storage unit, and the handles 5 are fixedly connected to both ends of the hand-held rod 4.

[0027] Foot pedals 12 are hinged to both sides of the blowing structure 13. The blowing structure 13 is the nozzle. The handheld mechanism and the air storage unit are fixedly connected through the housing 2, and the controller 1 is fixed to the housing 2. The controller 1 can be a PLC controller 1. A pressure sensor 11 is connected to the blowing structure 13 to detect the blowing pressure. The pressure sensor 11 has a range of 0 to 1 MPa, and the signal output to the PLC is 4 to 20 mA.

[0028] See Figure 2 Controller 1 is a PLC touch screen control all-in-one machine (HMI224-T). The input terminals of controller 1 are connected to pressure sensor 11 and control valve 8. The range of pressure sensor 11 is 0-200 degrees; the signal output to the PLC is 4-20mA. Control valve 8 is an electric ball valve Q911F-16P with a range of 0-50 rpm, and the signal output to the PLC controller is 4-20mA. A micro relay is connected between the PLC, control valve 8, and pulse valve 9; the micro relay is HF41F-24-ZS. The opening angle of control valve 8 is adjusted to change the gas pressure and flow rate in the gas storage tank 10. The control signal of control valve 8 is 4-20mA, that is, when 4mA is input, control valve 8 is closed, and when 20mA is input, control valve 8 is fully open.

[0029] When cleaning the filter bags using the independent bag cleaning device, the operator holds both ends of the holding mechanism, aligns the jetting structure 13 with the filter bag inlet of the dust collector, flips the foot pedal 12 so that it is placed flat on both sides of the filter bag inlet, and steps on the foot pedal 12 to fix the jetting structure 13 in the middle position of the inlet. The air inlet control valve 8 of the air storage unit is opened, and the air source enters the air storage tank 10 through the air inlet pipe 7 to fill it. The pressure is directly read from the pressure gauge 6 to obtain the pressure status inside the air storage tank 10. When the working pressure ≥ 0.6 MPa, it indicates that the tank is overfilled; when 0.6 ≥ 0.2 MPa, it indicates that the tank is full, and filling is stopped. Opening the pulse valve 9 allows gas from the air tank 10 to pass through the pulse valve 9, the blowpipe 3, and finally the blowpipe structure 13, instantly ejecting 0.2–0.6 MPa compressed air within 0.2 seconds. This high-speed airflow instantly fills the filter bag tube, creating a high-speed vibration effect through contact with the filter bag, shaking off the dust adhering to the outer wall of the bag. The dust then falls freely into the ash hopper, where it is collected and processed by a collection device.

[0030] This invention solves the problem of poor vibration effect of some filter bags in baghouse dust collectors during daily production. It can clean individual filter bags while the dust collector is stopped, extending the service life of the filter bags by more than one year and reducing on-site dust during maintenance.

However, it should be understood that this utility model is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions. Due to space limitations and for the sake of brevity, not all of these combined solutions have been described. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
