Abstract
The utility model discloses a dust removing device for a grain cleaning screen. The dust removing device comprises a dust proofing cover provided with multiple layers of filtering screens and an air guiding tube connected to one side of the dust proofing cover provided with multiple layers of the filtering screens. The dust proofing cover provided with multiple layers of the filtering screens and the peripherical gaps of the cleaning screen are sealed through canvas strips. The upper end of the dust proofing cover provided with the multiple layers of the filtering screens is provided with two air inlets in a same row, and the two air inlets are communicated with a V-shaped branch air pipe connected to an air blower. The air guide tube extends to one end of the cleaning screen and is connected to a dust removing fan. The dust removing device is simple and reasonable in structure, attractive in appearance, convenient to mount and use, the problem that impurities of dust and the like fly when grains are cleaned is solved effectively, environment of the working site is guaranteed, and environment pollution is reduced greatly.
Description
Technical field
The utility model relates to the grain processing process field, is specially a kind of grain cleaning sieve dust arrester.
Background technology
Existing compound grain cleaning sieve, because main air blower wind-force is excessive, grain and foreign material are blown afloat simultaneously, while blowing afloat, foreign material are higher, thin mixing will be flown upward to surrounding with dust thereupon, especially from charging aperture and anterior screen box dust, flies upward especially severe, and dust can't be collected, cause very large environmental pollution to Active workings, need to be improved.
The utility model content
The purpose of this utility model is to provide a kind of grain cleaning sieve dust arrester, to solve grain cleaning sieve traditional in prior art in use, because main air blower wind-force is excessive, grain and foreign material are blown afloat simultaneously, while blowing afloat, foreign material are higher, and thin mixing will be flown upward to surrounding with dust thereupon, especially from charging aperture and anterior screen box dust, flies upward especially severe, dust can't be collected, and causes the problem of very large environmental pollution to Active workings.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of grain cleaning sieve dust arrester, it is characterized in that: the dust cover of multiple filtration net is arranged in including and be connected in the ventilating duct of dust cover one side of multiple filtration net is arranged, in described, there is the dust cover of multiple filtration net to be installed on cleaning sieve top by mounting bracket, in described, there is the dust cover of multiple filtration net to seal by woven belt with the peripheral gap of cleaning sieve, in described, there is the dust cover upper end of multiple filtration net to be provided with side by side two air inlets, be communicated with inverted V-shaped on described two air inlets and divide branch wind pipe, described inverted V-shaped divides on branch wind pipe and is connected with air blast, described ventilating duct extends to cleaning sieve one end, and be connected with dedusting fan.
Described a kind of grain cleaning sieve dust arrester is characterized in that: described woven belt top edge has the dust cover periphery of multiple filtration net in being screwed and being arranged on, and lower limb falls in cleaning sieve periphery.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, and good looking appearance is easy to install, has effectively solved when grain is cleared up, and the problem that dust and other impurities is flown upward, guaranteed the environment of work-yard to have reduced greatly environmental pollution.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of grain cleaning sieve dust arrester, the dust cover 1 of multiple filtration net is arranged in including and be connected in the ventilating duct 2 of dust cover 1 one sides of multiple filtration net is arranged, inside there is the dust cover 1 of multiple filtration net to be installed on cleaning sieve 3 tops by mounting bracket, inside there is the dust cover 1 of multiple filtration net to seal by woven belt 4 with the peripheral gap of cleaning sieve 3, inside there is dust cover 1 upper end of multiple filtration net to be provided with side by side two air inlets, be communicated with inverted V-shaped on two air inlets and divide branch wind pipe 5, inverted V-shaped divides on branch wind pipe 5 and is connected with air blast 6, ventilating duct 2 extends to cleaning sieve 3 one ends, and be connected with dedusting fan 7.
Woven belt 4 top edges have dust cover 1 periphery of multiple filtration net in being screwed and being arranged on, lower limb falls in cleaning sieve 3 peripheries.
