Description

Automatic cleaning device for filter
Technical Field
The invention relates to the field of filter cleaning, in particular to an automatic filter cleaning device.
Background
In various mechanical equipment, a fuel oil filter and a lubricating oil filter exist, and the filter is dirty and blocked after being used for a long time, so that the normal operation of the equipment is influenced; in addition, a fresh water filter for filtering fresh water and an air filter for filtering air are also easily clogged. The original filtering function of the filter is lost after the filter is filthy and blocked, even the pipeline where the filter is located is blocked, which causes serious consequences. The degree of filth blockage is different due to different environments in which different filters work. In order to save the user's expenditure and the recycling of resources, the soiled filter needs to be cleaned in order to restore the original function of the filter as much as possible.
The existing filter cleaning method is to remove the filter from the equipment and put the filter to be cleaned into a chemical agent or light diesel oil with strong corrosiveness for cleaning or soaking. After soaking or cleaning, the filter is blown off by compressed air or high-pressure water, so that part of the filtering function of the filter is recovered. At present, the filter cleaning modes for ships and land mostly adopt manual cleaning, but the manual cleaning filter has the following defects:
in the process of soaking and cleaning the filter, although protective equipment is used, the filter still can be contacted with chemical agents and light diesel oil to different degrees, and the filter causes harm to human bodies. Wherein the chemical agent can cause different degrees of injuries to human bodies, such as skin corrosion, eye burn and the like; various additives contained in the light diesel oil can also cause harm to human bodies, such as skin itching after contacting the light diesel oil.
The chemical agent and light diesel oil soaked in the filter and oily water cleaned by clear water have the problems of how to treat and the like.
After the filter is cleaned in chemical agents and light diesel oil, high-pressure air or water is required to blow off the filter, and the chemical agents or diesel oil particles mixed in the air after blowing off are easy to suck into the lung, so that the lung function is reduced; meanwhile, the particles floating in the air can cause pollution to the surrounding environment.
After the filter is soaked, cleaned and blown, some filters still cannot achieve ideal use effect, and the economy is low.
In conclusion, the filter is cleaned manually, personal injury and environmental pollution are caused, time, manpower and material resources are wasted, and the cleaning effect is general.

After 3 minutes of forward and reverse rotation cleaning, the PLC firstly controls the closing action of the electric ball valve I85 and the electric ball valve II 86, then controls the opening action of the electric ball valve III 87, so that the cleaning liquid mixed with impurities after being cleaned by the filter 8 is filtered by the electric ball valve III 87 and the filter 8, the filtered clean cleaning liquid enters the discharging cabinet 22 and enters the oil collector 9 through the check valve, and the clean cleaning liquid is manually sent back to the cleaning liquid tank 69, so that the cleaning liquid can be recycled. The number of times and the time for recycling the cleaning liquid can be determined according to the degree of contamination of the cleaning liquid. In the slow cleaning process, the cleaning solution mixed with impurities needs to be discharged periodically to prevent the cleaning solution from overflowing from the device. The time and the time interval of the discharge can be set according to the actual situation, that is, the opening time of the electric ball valve iii 87 is set. Since during slow cleaning it is possible to have too high a liquid level at the filter 58 to be cleaned, which could affect the cleaning effect, the liquid level is controlled at 1/5 at the height of the filter to be cleaned. In actual use, the automatic discharge time is reasonably set according to the rising speed of the actual liquid level.
After the cleaning liquid is discharged, the electric ball valve III 87 is closed under the control of the PLC, the variable frequency motor 13 enters an acceleration stage, and the acceleration time can be set according to actual needs. After the acceleration of the variable frequency motor 13, the tiny impurities and dirty and blocked filter pore canals attached to the filter are activated again by the action of centrifugal force; at the same time, the cleaning liquid on the filter 58 to be cleaned is thrown off the surface of the filter 58 to be cleaned under the action of centrifugal force, so that a clean, clean and dry filter is obtained.

The filter 58 to be cleaned is arranged on the vertical shaft top seat 80, the pressure plate I81 is arranged above the filter 58 to be cleaned, and the filter 58 to be cleaned is tightly pressed between the vertical shaft top seat 80 and the pressure plate I81.
The variable frequency motor 13 is started, and the main gear, the pinion, the vertical shaft II, the vertical shaft footstock and the filter to be cleaned are driven to rotate by the connecting main shaft. Simultaneously on the control screen, select under the washing mode by "inside to outside washing" function key, press the start button, under PLC's control, according to the settlement of cleaning air pressure and cleaning solution flow, through adjusting the aperture of adjusting I85 of electric ball valve and II 86 of electric ball valve, wash the filter, pressure sensor 63 and flow sensor 67 feed back the actual signal who detects to PLC simultaneously to reach the abluent effect of accurate control.
When the filter to be cleaned rotates, under the control of the PLC, the system automatically selects a nozzle main pipe III 73 as a main injection pipeline to clean the filter; or by manually selecting the nozzle manifold iii 73 as the main injection line, the filter 58 to be cleaned is cleaned. After the electric ball valve II 86 is opened, compressed air enters the air distribution manifold 64 through the electric ball valve II 86, then passes through the gas valve assembly, then passes through the gas quick coupling III 62, and enters the gas quick coupling I19 of the quick coupling assembly 21. When the electric ball valve II 86 is opened, the PLC controls the electric ball valve I85 to be opened, cleaning liquid enters the cleaning liquid main pipe 66 through the electric ball valve I85, the cleaning liquid filter 68 and the flow sensor 67 and then enters the cleaning liquid main pipe 66 through the liquid valve assembly and then enters the liquid quick connector I20 of the quick connector assembly 21 through the liquid quick connector III 65 and is carried by gas at the gas quick connector I19, the cleaning liquid is carried by high-pressure and high-speed gas by utilizing the principle of a spray pipe to form a high-speed and high-pressure mixture, and the mixture enters the nozzle main pipe III 73 and the nozzle III 77 to form fine needle-shaped linear flow which is directly sprayed to the inner surface of the rotary filter 58 to be cleaned, the spray mode is continuous spray, and impurities attached to the filter are removed. Corresponding valve elements in the liquid valve assembly and the gas valve assembly are opened manually or automatically and intermittently, so that the high-speed and high-pressure mixture enters the nozzle main pipe I25 and the nozzle I26 and is sprayed to the outside of the filter 58 to be cleaned, the outer surface of the filter is cleaned, the permeability of the filter is detected, and the cleaning effect is improved.
Otherwise, the same procedure as in example 1 was repeated.
