The utility model relates to a multiplex pulse airflow mechanical automatic control box, which comprises an air box, a star-shaped gate divider and a drive system, wherein, the an air inlet, a blowback wind gap and a pressure release gap are arranged on the air box, a blowback air valve is arranged on a position corresponding to the blowback wind gap in the air box, the star-shaped gate divider rotatablely arranged in the air box and is connected with the drive system, a triggering structure which controls the open and close of the blowback air valve is arranged on the star-shaped gate divider, and the pressure release gap is provided with a pressure limiting device. The automatic control box controls the open and closes of a blow-back-air valve in a purely mechanical method to generate pulse airflow, does not need high-pressure gas to control the conduction of the valve, eliminates a plurality of electronic control components and electronic control systems, and has simple structure, reliable work and use cost reservation.
Description
Technical field
The utility model relates to a kind of multiplex pulse air-flow machinery automatic control box, especially for the machinery of the multiplex pulse air-flow on blowback wind dust-precipitator automatic control box.
Background technology
In the industrial production of industries such as metallurgy, mining industry, because some feed particles is thinner, some raw material dust can float in the air in process of production, has both caused pollution, wasted raw material again. in order to address this problem, generally use bagroom to collect airborne raw material dust.The operation principle of bagroom is such: under blower fan drives, the gas that the negative pressure that aspiration channel produces will contain the raw material dust sucks bagroom, filtration through cloth bag, air is discharged in cloth bag, and dust then major part drops in the disposal box, and small part is adsorbed on the outer surface of cloth bag, so after work a period of time, the outer surface of cloth bag will adsorb more dust, and this makes the gas permeability of cloth bag reduce, thereby has influenced the effect of gathering dust.In order to address this problem, also be provided with reverse-blow pipe in the bagroom, reverse-blow pipe links to each other with the blowback wind system.Existing blowback wind system uses electronic valve to control the break-make of each road blowback wind circuit, because electronic valve only just can conducting during greater than 3MPa in air pressure, therefore will be equipped with an air accumulator pressure store gas could guarantee system's operate as normal.Working pressure gas has increased the breakage rate of filter bag in addition, has strengthened cost of use.
The utility model content
The purpose of this utility model provides a kind of multiplex pulse air-flow machinery automatic control box, and equipment could operate as normal when solving that pressure is greater than 3MPa in the prior art, and lacks the problem of economy.
For achieving the above object, the utility model adopts following technical scheme: multiplex pulse air-flow machinery automatic control box, comprise gas tank, star branch door device and drive system, gas tank is provided with air inlet, blowback air port, pressure relief opening, corresponding position, blowback air port is provided with the blowback air-valve in the gas tank, the control end of the blowback air-valve star that is connected in rotation is installed on gas tank and with drive system outside the gas tank is divided in the control range of door device, and pressure relief opening is provided with pressure limiting device.
It is one that described star is divided the door device, be laid with the radial fingertip that is fixed on the axle along its axis, fingertip is corresponding with corresponding blowback air valve position respectively vertically, and per two adjacent fingertips divide door device week phase difference to be arranged upwards star, and per two adjacent phase differences divide the door device same as upwards equating star.
Described pressure limiting device is a relief valve, safety valve or overflow valve.
Described drive system is made up of motor and decelerator, and drive system drives star and divides the door device to rotate.
Described drive system is made up of motor and belt drive unit, and drive system drives star and divides the door device to rotate.
When adopting the multiplex pulse air-flow machinery automatic control box use of such scheme, external air source is the gas tank air feed by air inlet, drive system drives star and divides the door device to rotate, star divides the fingertip on the door device respectively corresponding blowback air-valve, star is divided in the door device rotation process, fingertip is successively to the effect of blowback air-valve, make the blowback air-valve carry out break-make successively, thereby in each reverse-blow pipe, form air pulse, this kind mode adopts the folding of frame for movement control valve, do not re-use gases at high pressure and control the folding of blowback air-valve, reduced requirement air pressure.Pressure limiting device is housed on the gas tank, and when air pressure was higher than default pressure, pressure limiting device releasing pressure automatically assurance system worked under environment under low pressure, has reduced the breakage rate of filter bag.This scheme uses the folding of pure mechanical mode control blowback air-valve to produce air pulse, has saved a plurality of electronic control components and electronic control system, and simple in structure, reliable operation can be saved use cost again.
