Description

Anti-blocking dust remover

Technical Field

The utility model relates to dust collecting equipment, in particular to a dust remover.

Background

The dust remover is a dust collecting device widely used in various industrial enterprises, the operation condition of the dust remover directly relates to whether production can be smoothly carried out, and the dust remover is also an occupational health device. The bag type and cylinder type dust collector is the most widely used dust collector, including box body, pulse blowing device, filtering bag (cylinder), dust collecting bucket, dust discharging valve and blanking cylinder, and its working principle is that the dust in the production field is sucked into the dust collector by means of dust-removing fan, and after filtered by means of bag type or cylinder type filter, the filtered clean air is discharged into atmosphere or passed through the peculiar smell treatment equipment and discharged into atmosphere, and the dust remained on the external surface of filtering bag (cylinder) is separated from filtering bag under the action of pulse blowing gas, and can be fallen into dust collecting bucket under the action of gravity, and can be discharged by means of dust discharging valve and blanking cylinder.

In the actual operation of the dust remover, when some wet dust or long-stem materials enter the dust collecting hopper, if the dust amount is larger, an arch bridge is easily formed at the upper part of the dust discharging valve, so that the materials such as dust in the dust collecting hopper cannot enter the dust discharging valve, if the materials are found to be timely, the dust remover needs to shut down and then opens the observation dredging door, and then manually dredges the materials; if the discovery is not timely, then will cross filter bag (a section of thick bamboo) clearance after a certain time and block up completely for the unable circulation of dust removal air just needs the manual work to open filter bag (a section of thick bamboo) apron on the dust removal box this moment, takes off the jetting pipe, then takes out filter bag (a section of thick bamboo) and just can dredge. The operation process can be completed by continuously operating four workers for more than four hours, meanwhile, the field dust concentration is high in the operation process, safety accidents such as dust explosion are easily caused, and occupational health hazards can be caused to the operators if the operators are not protected properly.

Disclosure of Invention

The utility model aims to provide an anti-blocking dust remover which can automatically dredge dust materials when the dust materials are blocked, so that the normal operation of the dust remover is ensured.

The utility model relates to an anti-blocking dust remover, which comprises a dust collecting hopper, a dust discharging valve and a dust discharging barrel, wherein the dust discharging valve is fixedly installed at the lower end of the dust collecting hopper; still include control box, gas holder and pulse valve, the control box is connected with ultrasonic wave material level inductive switch and pulse valve electricity respectively, and the break-make through ultrasonic wave material level inductive switch controls opening and closing of pulse valve, and the gas holder passes through the gas-supply pipe to be connected with the air nozzle, the pulse valve is installed on the gas-supply pipe.

When the dust material blocks and shields the induction head of the ultrasonic material level induction switch, the ultrasonic material level induction switch is switched on, the pulse line in the control box is electrically switched on, the pulse controller is used for instantly switching on the pulse valve, the pulse valve is opened, and compressed air in the air storage tank is sprayed out through the air nozzle to dredge the blocked dust material.

The utility model is provided with the ultrasonic material level sensing switch, when the dust material is blocked to a certain degree, the blocked dust material can be automatically dredged through the air nozzle, so that the dust remover can always keep normal operation, and the trouble of manually cleaning the equipment, the shutdown caused by the trouble and the possible safety accidents are eliminated. The ultrasonic material level sensing switch can adopt an explosion-proof ultrasonic material level sensing switch, and can effectively prevent dust explosion in the dust collecting hopper caused by electric sparks, so that the equipment is safe to operate.

Drawings

FIG. 1 is a front view of the anti-clogging dust collector of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figure 1, the anti-blocking dust collector comprises an ash collecting hopper 4, an ash discharging valve 5, a dust falling cylinder 6, a control box 1, an air storage tank 11 and a pulse valve 9, wherein the ash discharging valve 5 is fixedly installed at the lower end of the ash collecting hopper 4, the dust falling cylinder 6 is fixedly installed at the lower end of the ash discharging valve 5, and an observation and dredging door 2 for observation and maintenance is arranged at the middle lower part of the ash collecting hopper 4. Be provided with explosion-proof type ultrasonic wave material level inductive switch 3 in ash collecting bucket 4, this ultrasonic wave material level inductive switch 3 passes through L shape mount pad 8 installation to be fixed on ash collecting bucket 4 inner wall, and its highly lies in ash collecting bucket 4 lower extreme and observes between dredging door 2 and be close to the below of observing dredging door 2 department, is provided with air nozzle 7 at ash collecting bucket 4 lower extreme, and air nozzle 7 inclines upwards towards the inner chamber of ash collecting bucket 4. Control box 1 is connected with ultrasonic wave material level inductive switch 3 and pulse valve 9 electricity respectively, and the break-make through ultrasonic wave material level inductive switch 3 comes opening and closing of control pulse valve 9, and gas holder 1 passes through the gas-supply pipe 10 to be connected with air nozzle 7, pulse valve 9 is installed on the gas-supply pipe 10.

When the dust material blocks and blocks the induction head of the ultrasonic material level induction switch 3, the ultrasonic material level induction switch 3 is switched on, the pulse line in the control box 1 is electrically switched on, the pulse controller is used for instantly switching on the pulse valve 9, the pulse valve 9 is opened, and the compressed air in the air storage tank 10 is sprayed out through the air nozzle 7 to dredge the blocked dust material.
