Abstract
The utility model relates to a cylinder screen mesh cleaning device. The device is characterized in that the device comprises a gas source, a gas storage tank, a plurality of gas delivering pipes, control valves, electromagnetic valves and spray nozzles, wherein the gas storage tank is connected with the gas source; the gas delivering pipes are communicated with the gas storage tank; the control valves, the electromagnetic valves and the spray nozzles are arranged on each gas delivering pipe; and each electromagnetic valve is respectively controlled by a programmable logic controller (PLC) system. Two gas delivering pipes are grouped into one group, and are arranged on the periphery of the cylinder screen by a sectional type. When the gas is sprayed and blown each time, one or few of gas delivering pipes are controlled to ventilate, thereby ensuring the gas pressure. The utility model adopts PLC to control the opening and closing of the electromagnetic valve to realize intelligent control, and simultaneously only uses gas to generate spraying and blowing force to the cylinder screen to make the cylinder screen vibrate, thereby having no damage to equipment.
Description
Technical field
The utility model relates to the screen cloth Removal Technology, especially about a kind of drum sieve mesh cleaning plant.
Background technology
MAP device screening machine adopts the industrial mechanical HS-80 of the Co., Ltd type two-layer cylinder sieve of Beijing morning twilight.This drum sieve screen cloth clearing apparatus adopts the ratchet-type hammer to impact the screen cloth press strip, and the vibration that impacts generation is passed to screen cloth, thereby the granular material that screen cloth stops up is cleared up.Weaken owing to the impact force of this manner of cleaning up is mainly born by press strip, the vibration that screen cloth is subjected to is less, and cleaning effect is not good.Hammer impacts press strip continuously in addition, causes the damage of press strip easily.In order to improve the continuous cycle of operation of cleaning effect and drum sieve, need counter-blow hammer and screen cloth press strip repeatedly to rectify and improve and keep in repair.
Under the prerequisite that guarantees cleaning effect, the existing screen cloth press strip that adopts is 100 * 10 band iron.Even if select such band iron for use, the continuous cycle of operation of drum sieve also can only remain on 10～15 days.The frequent breakage of press strip has had a strong impact on the continuous operation of equipment, has increased maintenance cost and operating cost.
Summary of the invention
At the problems referred to above, the utility model purpose provides a kind of novel drum sieve mesh cleaning plant, and this device adopts new self-cleaning technology, overcomes the deficiency of existing equipment, avoids the damage to equipment under the prerequisite of raising cleaning effect.
For achieving the above object, the utility model is taked following scheme: a source of the gas is set, and source of the gas connects an air accumulator, draws many appendixs on the air accumulator sidewall outward, the quantity of appendix determines according to drum sieve that with arranging general per two appendixs are that use is closed in an assembly.On each root appendix, all be connected with control valve and magnetic valve, be connected with nozzle, nozzle subtend screen drum in the end of appendix.When material is equipped with in drum sieve inside, in the drum screen material, self-cleaning device starts under driven by motor, and screen drum is jetted, and high-speed compressed air makes screen drum produce vibration, the granule materials that is stuck on the mesh is shaken off, thereby the maintenance mesh is unimpeded.
Described magnetic valve is controlled by PLC, in the course of the work, can control one or a few magnetic valve unlatching work by PLC, according to the gas-storing capacity and the gas output of design, and the size of screen drum, the quantity that the decision magnetic valve is opened.When some magnetic valves were worked, other magnetic valve rested, and solves a plurality of nozzles problem of source purge gas insufficient pressure together.Control valve plays the security protection effect.
The utility model is owing to take above scheme, it has the following advantages: 1, connect many appendixs on the air accumulator, magnetic valve is installed on the appendix, guiding compressed air is as the screen cloth source purge gas, carry out integrated control magnetic valve with PLC, nozzle is purged to reach the purpose of screen cloth cleaning screen cloth by setting requirement.2, adopt the magnetic valve of the integrated control of PLC to purge Removal Technology, following advantage is arranged: solved a plurality of nozzles problem of source purge gas insufficient pressure together, guaranteeing instantaneously under the prerequisite of pressure to have only one or a few nozzle operation, saved compressed air.Compressed air is emitted in magnetic valve moment startup, induces the high fast direction screen cloth of auxiliary air of several times pressure, thereby screen cloth is produced a bigger vibration, and cleaning effect is better, and the less air consumption and the cycle purge of setting are lower to the burden requirement of equipment purging.3, the utility model only relies on gas that screen drum is produced winding-up power, makes the screen drum vibration, to the equipment not damaged.
Description of drawings
Fig. 1 is the utility model structure and the application drawing when using in conjunction with drum sieve
Fig. 2 is the A place partial enlarged drawing of Fig. 1
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises a source of the gas 1, and source of the gas 1 links to each other with air accumulator 2, and source of the gas 1 is collected air and constantly carried to air accumulator 2.The outer many appendixs 3 of drawing on air accumulator 2 sidewalls, the quantity of appendix 3 is determined according to the length of drum sieve, general per two appendixs are that use is closed in an assembly, a certain local segment to drum sieve is jetted, purpose is to prevent that another root can in time replenish work when wherein appendix damages.On each root appendix 3, all be connected with control valve 4 and magnetic valve 5, be connected with nozzle 6 in the end of appendix 3.
The above-mentioned self-cleaning device that is made of source of the gas 1, air accumulator 2, appendix 3, control valve 4, magnetic valve 5 and nozzle 6 is placed on the outside of drum sieve 7, nozzle 6 subtend screen clothes.When material is equipped with in drum sieve inside, when rolling under motor 8 drives, self-cleaning device starts, and simultaneously screen drum is jetted, and high-speed compressed air makes screen drum produce vibration, and the granule materials that is stuck on the mesh is shaken off, and the maintenance mesh is unimpeded.
In the utility model, each magnetic valve 5 in the course of the work, can be controlled one or several magnetic valve unlatching work by PLC by PLC control.According to the gas-storing capacity and the gas output of design, and the size of screen drum, the quantity that the decision magnetic valve is opened.When some magnetic valves were worked, other magnetic valve rested, and has solved a plurality of nozzles problem of source purge gas insufficient pressure together, has saved compressed air.Compressed air is emitted in magnetic valve moment startup, induces the high fast direction screen cloth of auxiliary air of several times pressure, thereby screen cloth is produced a bigger vibration, and cleaning effect is better.
