Wherein, the discharge valve is butterfly valve.
The utility model has the following beneficial effects: when needing to clean the filter in filter device, back washing pipe
The inner cavity of filter is protruded into, back washing pipe, which accesses, provides the air compression system of high pressure gas, controller pulse control electromagnetic valve work, from
And the high pressure gas pulse compartment of terrain of back washing pipe is made to enter the outer wall of filter from the inner wall of filter, thus the filter of filter
Online dust is blown off, and this makes it possible in the case where not breaking through filter and taking out from filter device, so that it may to filter
It is cleaned.
Detailed description of the invention
Using attached drawing, the utility model is described in further detail, but the embodiment in attached drawing is not constituted to the utility model
Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached
Figure obtains other attached drawings.
Fig. 1 is the structural schematic diagram of the filtering device of the utility model embodiment.
Fig. 2 is the schematic diagram of internal structure of the second filter vat in the utility model embodiment.
Include: 1 in figure --- the first filter vat, 11 --- blast pipe, 12 --- first butterfly valve, 2 --- the second filter vat,
21 --- ventilation duct, 22 --- top cover, 23 --- filter, 24 --- discharge pipe, 25 --- back washing pipe, 251 --- air intake,
252 --- venthole, 26 --- solenoid valve, 27 --- controller, 28 --- second butterfly valve, 3 --- bracket.
Specific embodiment
The utility model is further described with the following Examples.
As shown in Figure 1, being provided with the first filter vat 1 (left side in Fig. 1) and the second filter vat 2 (right side in Fig. 1 on bracket 3
Side), there is ventilation duct 21 between the first filter vat 1 and the second filter vat 2 in succession, the top of the first filter vat 1 is connected with blast pipe
11, the inner wall of the first filter vat 1 is equipped with the pipeline (being not drawn into figure) of spiral, and the gas for needing to filter enters from the blast pipe 11
In first filter vat 1, these gases are flowed through the pipeline of these spirals, and the dust or impurity of such bulky grain will be attached to spiral shell
The inner wall of the pipeline of rotation, then under the effect of gravity, the dust or impurity of these bulky grains will fall to the bottom of the first filter vat 1
Portion, and the bottom of the first filter vat 1 is equipped with first butterfly valve 12, when needing to clear up the dust or impurity in the first filter vat 1, then
First butterfly valve 12 can be opened, such dust or impurity will be dropped out directly under gravity.
Gas after 1 simple filtration of the first filter vat further includes some short grained dust or impurity, therefore the first mistake
The filtering gas of lauter tub 1 enters in the second filter vat 2 through ventilation duct 21 further to be filtered.As shown in Fig. 2, the second filtering
Bucket 2 is equipped with top cover, and the bottom of top cover is equipped with barrel-shaped filter 23, is communicated with discharge pipe 24 at the top of top cover, was needing
When air filtration body, discharge pipe 24 accesses air compressor machine (being not drawn into figure), and air compressor machine exhausting is so that 23 inner cavity of filter forms negative pressure, and the
Gas in two filter vats 2 enters its inner wall from the outer wall of filter 23, to filter the gas, small in the gas in this way
The dust or impurity of grain will be attached on the strainer of pass filter.The inner cavity for protruding into filter 23 is additionally provided at the top of the top cover
Back washing pipe 25, the air intake 251 of back washing pipe 25 are provided with solenoid valve 26, and solenoid valve 26 is connected with controller 27.When needs are to mistake
When filter 23 is cleaned, the air intake 251 of back washing pipe 25 accesses air compression system (being not drawn into figure), and air compression system provides high pressure
Gas, 27 pulse control solenoid valve 26 of controller work, to make the high pressure gas pulse compartment of terrain of back washing pipe 25 from filter
23 inner wall enters the outer wall of filter 23, so that dust on the strainer of filter 23 is blown off, this makes it possible to not punching
