The fully-automatic back washing filter is supplied with self-cleaning power completely from compressed air without a motor speed reducer, and is energy-saving and environment-friendly; during washing, normal filtration of the filter is not affected, and the outlet pressure of the filter does not fluctuate; the whole fully-automatic back washing filter is compact in design, small in size and suitable for horizontal or vertical installation, can be applied to continuous cleaning filtration in various oil systems, can continuously operate even under the condition of low flow speed and low pressure, and is convenient to maintain and economic.
Description
Technical field
The present invention is specifically related to a kind of full-automatic back washing filter.
Background technology
Existing Full automatic backwashing filter major part is to adopt reductor to drive filter core to rotate, aim at drain outlet by filter core local area utilizes moment pressure reduction to carry out backwash simultaneously, the problem of this structure is, this backwash mode is to utilize the fluid of outlet to carry out backwash, the pressure of outlet can decline, thereby causes the serious consequence inadequate into machine pressure.Because fuel oil has viscosity, in the time that cartridge surface is very dirty, can rushes and not wash clean in addition.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the invention provides a kind of full-automatic back washing filter, adopt compressed air back-washing, it is rational in infrastructure, easy for installation, safeguards economical, safe and reliable, outlet pressure ripple disable when recoil, can directly avoid above-mentioned deficiency.
Technical scheme: a kind of full-automatic back washing filter, comprise base, body, terminal box, differential pressure transmitter device, filter chamber, actuator, gas dome, six-way valve and by-pass filter, body is fixedly housed on described base, body is provided with filter chamber, terminal box and gas dome are installed respectively in filter chamber two ends, differential pressure transmitter device is housed in terminal box, actuator is housed on gas dome, other six-way valve and the by-pass filter of being connected with in turn of described gas dome.
As optimization: be provided with filter core in described filter chamber.
As optimization: the number of described filter core is 1-4.
As optimization: be also provided with oil inlet, oil export and sewage draining exit on described filter.
As optimization: be also provided with guiding valve and rotary valve on described filter, rotary valve is provided with oil filler point.
Beneficial effect: the complete pneumatically of the present invention provides self-cleaning power, without motor reducer, energy-conserving and environment-protective; When flushing, do not affect the normal filtration of filter, the outlet pressure ripple disable of filter; Overall design compactness, small volume, be suitable for level or at right angle setting, can be applicable to the lasting cleaning and filtering in all kinds of oil systems, even still can continuous service in the situation that of low flow velocity, low pressure, and economy easy to maintenance.By full-automatic flushing device, filter element is carried out to back flush with compressed air, to keep filter all the time in a kind of cleaner state, filter always has a clean filter chamber as for subsequent use.This model filter has two filter chambers, a job, and one is for subsequent use.And be applicable to the filtration of fuel oil, lubricating oil, hydraulic oil, quenching press wet goods plurality of liquid medium, can be applicable to multiple industries such as shipbuilding industry, oil industry, power station, iron and steel manufacturing industry, ic engine industry.

Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment
As shown in Figure 1, 2, 3, a kind of full-automatic back washing filter, comprise base 12, body 2, terminal box 13, differential pressure transmitter device 14, filter chamber 3, actuator 7, gas dome 10, six-way valve 15 and by-pass filter 16, body 2 is fixedly housed on base 12, body 2 is provided with filter chamber 3, and terminal box 13 and gas dome 10 are installed respectively in filter chamber 3 two ends, and differential pressure transmitter device 14 is housed in terminal box 13, actuator 7 is housed, other six-way valve 15 and the by-pass filter 16 of being connected with in turn of gas dome 10 on gas dome 10.In filter chamber 3, be provided with filter core 4.The number of filter core 4 is 1-4.On filter, be also provided with oil inlet 1, oil export 6 and sewage draining exit 17.On filter, be also provided with guiding valve 9 and rotary valve 8, rotary valve 8 is provided with oil filler point 11.
Filter liquide enters filter bottom oil inlet 1, flows into the rear arrival filter chamber 3 of body 2, and then ecto-entad is by filter core 4, and the impurity that is wherein greater than regulation filtering accuracy is detained by filter screen, and the clean liquid 5 after filtration flows to filter upper end filter oil export 6.Along with the increase of filter working time, more and more be trapped in the impurity on filter core 4, the pressure differential that causes filter to import and export two ends constantly rises, in the time that pressure differential reaches a certain particular value, differential pressure transmitter device 14 sends signal, triggers electrical system, now actuator 7 commutates, drive rotary valve 8 to forward to the filter chamber position that needs to rinse from filter chamber for subsequent use, the clean filter core 4 in filter chamber for subsequent use is participated in filtration, causes filter pressure reduction at once to decline.
Due to the effect of actuator 7 and ratchet wheel relay, rotary valve 8 needs the filter chamber position of rinsing to stop action once forward to, pneumatic actuating device by electrical control starts, control air is emptying, open guiding valve 9, compressed air in gas dome 10 impels the liquid reverse flow in filter chamber to cross filter core 4 simultaneously, and the impurity being bonded on filter screen is rinsed out.
Through the backwash of short time, magnetic valve resets, and controls air and enters, in the middle of forcing, guiding valve 9 moves down, seal the compressed air in gas dome 10, now carry out fluid infusion by the oil filler point 11 on rotary valve through flushing and emptying filter chamber, the air in filter chamber is discharged by automatic exhaust device.
In normal operation, the valve disc of guiding valve 9 bottoms is closed sewage draining exit 17, and compressed air is gathered in gas dome, prepares to carry out backwash.
For those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
The complete pneumatically of the present invention provides self-cleaning power, without motor reducer, and energy-conserving and environment-protective; When flushing, do not affect the normal filtration of filter, the outlet pressure ripple disable of filter; Overall design compactness, small volume, be suitable for level or at right angle setting, can be applicable to the lasting cleaning and filtering in all kinds of oil systems, even still can continuous service in the situation that of low flow velocity, low pressure, and economy easy to maintenance.By full-automatic flushing device, filter element is carried out to back flush with compressed air, to keep filter all the time in a kind of cleaner state, filter always has a clean filter chamber as for subsequent use.This model filter has two filter chambers, a job, and one is for subsequent use.And be applicable to the filtration of fuel oil, lubricating oil, hydraulic oil, quenching press wet goods plurality of liquid medium, can be applicable to multiple industries such as shipbuilding industry, oil industry, power station, iron and steel manufacturing industry, ic engine industry.
