The negative pressure dust removing device that a kind of integrated house wood plastic product is produced
The utility model relates to the negative pressure dust removing device that a kind of integrated house wood plastic product is produced.
Wood plastic composite is a kind of novel material, is by the shell of waste and old wood, sawdust, agricultural crop straw, nut according to certain ratio, mixes and make through high temperature high pressure process, have acid and alkali-resistance, the advantages such as imputrescibility with thermoplastic.
But produce local in this wood plastic composite production process and can produce a large amount of dust, contaminated environment, affect producers healthy.
Utility model content
The purpose of this utility model is, the negative pressure dust removing device providing a kind of integrated house wood plastic product to produce, effectively can avoid environmental pollution, and the resource realizing dust is recycled.
The negative pressure dust removing device that a kind of integrated house wood plastic product that the utility model provides is produced, comprising:
Tank body, bottom is powder receiving system, and side top offers an air inlet;
Filter core, is arranged in described tank body, filters the air being mingled with dust;
Outlet conduit, is arranged on above described filter core, discharges through filtered air from described outlet conduit;
Weight baffle plate, is movably installed in described tank base, makes the bottom of described tank body keep closing or opening;
Splicing groove, is vertically mounted on below described tank body, and when described weight baffle plate is opened, dust falls into described splicing groove;
Blowback lines, is connected with described filter core, and after suction system starts continuously, stops pre-determined number, described blowback lines is opened automatically, and by dust blowout residual for described filter core, dust enters described splicing groove along described tank body barrel.
Preferably, one end of described weight baffle plate is provided with weight.
Preferably, described blowback lines comprises controller and cylinder, and after suction system starts continuously, stops pre-determined number, described controller controls blowback lines and automatically opens, and the dust that described filter core is residual is blown in described tank body by described cylinder by back draught.
The utility model has the advantage of:
1, invest little, efficiency of dust collection is high;
2, dedusting, blowback automation can be realized, reduce filter core dismounting number of times, reduce labour intensity, improve the service life of filter core;
3, realize the automatic collection of dust, avoid environmental pollution, achieve the recycling of dust.

Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the technological means of this device, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, be described in detail.
The utility model provides the negative pressure dust removing device that a kind of integrated house wood plastic product is as shown in Figure 1 produced, and comprising: tank body 1, outlet conduit 2, filter core 3, weight baffle plate 4, splicing groove 6, blowback lines 7.The bottom of tank body 1 is dust receiving system, and filter core 3 is arranged in tank body 1, and outlet conduit 2 is arranged on above filter core 3, weight baffle plate 4 is movably installed in the bottom of tank body 1, splicing groove 6, is vertically mounted on below tank body 1, blowback lines 7, being connected with filter core 3 communicates with outside air.
In addition in the present embodiment, one end of weight baffle plate 4 is provided with weight 5, like this because the Action of Gravity Field of weight 5 makes tank body 1 be kept closed.Blowback lines 7 comprises controller 71 and cylinder 72.
When feeding system is started working, the gas being mingled with dust enters tank body 1 from the air inlet 11 tank body 1, discharged by wind pipe 2 after filter core 3 filters, dust falls to weight baffle plate 4 place along the barrel of tank body 1 due to Action of Gravity Field, when the gravity of dust is greater than the gravity of weight 5, weight baffle plate 4 is opened automatically, and dust falls into splicing groove 6.But in this dust removal process, part dust can be attached on filter core 3.So after setting feeding system starts continuously, stops pre-determined number, the controller 71 of blowback lines 7 is opened automatically, and the dust that filter core remains oppositely is blown into tank body 1, and dust enters in splicing groove 6 along the barrel of tank body 1.Such automation blowback pattern, reduces filter core 3 dismounting wash number, reduces labour intensity, improve the service life of filter core 3, also improve the efficiency of dedusting, realize the full-automatic collection of dust, avoid environmental pollution.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
