Description
Technical field
The utility model relates to powder material load transfer device technical field, particularly a kind of spiral feeder that vacuumizes.
Background technology
Powder conveying equipment is widely used at food, the industries such as medicine and chemical industry, screw conveyor is simple in structure because of it especially, specification is many, the advantage such as applied widely becomes the first-selection of powder conveying equipment, but the development along with the powder industry, technology improves constantly, so that the granularity of powder material is more and more less, what have has reached nanoscale, because the granularity of powder material is more and more less, its proportion is corresponding also more and more less, this has brought very large difficulty with regard to the transportation work of giving this class powder material, adopt original common screw conveyor can't finish efficiently this class powder material transportation work, but also the phenomenon of flour dust overflow can occur in the process of carrying, not only caused waste also to pollute environment.
The utility model content
The utility model purpose is in order to overcome above-mentioned deficiency, a kind of spiral feeder that vacuumizes to be provided, can finish efficiently the transportation work to the little powder material of proportion, and the phenomenon of flour dust overflow can not occur.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of spiral feeder that vacuumizes, comprise housing, described enclosure interior is provided with conveyor screw, the outer ring of described housing is wound with the pressure distribution chamber, housing in the described pressure distribution chamber is provided with some air extractor vents, and the outside of some air extractor vents is provided with filter layer on the described housing, and described pressure distribution chamber connects compressed gas source and vacuum extractor.
As a kind of improvement, described filter layer comprises filter screen and is used for described filter screen is pressed in orifice plate on the described housing.
The beneficial effects of the utility model are: the spiral feeder that vacuumizes described in the utility model comprises the conveyor screw that is arranged in the housing, the outer ring of housing is wound with the pressure distribution chamber, housing in the pressure distribution chamber is provided with some air extractor vents, the outside of some air extractor vents is provided with filter layer on the housing, the pressure distribution chamber connects compressed gas source and vacuum extractor, because the pressure distribution chamber communicates with the inner chamber of housing, and the pressure distribution chamber connects vacuum extractor, then the air that is mingled with in the powder material can be extracted out, so that form vacuum in the housing inner chamber, this is just so that the increasing of the proportion of powder material, volume-diminished, be convenient to carry, because the outside of some air extractor vents is provided with filter layer on the housing, can guarantee in the process that vacuumizes, powder material can not extracted out, thereby the utility model can be finished the transportation work of the little powder material of proportion efficiently, and can not produce the phenomenon of flour dust overflow, namely protect environment to reduce again waste, for enterprise has reduced productive costs; Because the pressure distribution chamber also connects compressed gas source, can switch easily and fast the dual mode of bleeding and blow again, finish efficiently the blowback rapping work to filter layer, guarantee the work efficiency of pay-off.
Because filter layer comprises filter screen and is used for filter screen is pressed in orifice plate on the housing; orifice plate can play the effect of protection filter screen; prevent that filter screen is out of shape under the effect of gas; affect filter effect; prolonged the service life of filter screen; reduce the replacing number of times of filter screen, reduced the operating cost of pay-off, and further improved work efficiency.
In sum, the utility model is simple in structure, and long service life is easy to operate, can finish efficiently the transportation work to the little powder material of proportion, and can not produce the excessive phenomenon of powder, and actv. has protected environment to avoid the pollution of dust.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A section enlarged drawing of Fig. 1;
Among the figure: 1, housing, 2, inlet point, 3, discharging opening, 4, conveyor screw, 5, connection pipe, 6, the pressure distribution chamber, 7, filter layer, 70, orifice plate, 71, filter screen, 8, extraction pipe, 9, gas blow pipe, 10, shutoff valve, 11, air extractor vent.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.
Shown in Fig. 1 and Fig. 2 are common, a kind of spiral feeder that vacuumizes, comprise housing 1, housing 1 inside is provided with conveyor screw 4, the outer ring of housing 1 is wound with pressure distribution chamber 6, housing 1 in the pressure distribution chamber 6 is provided with some air extractor vents 11, and the outside of some air extractor vents 11 is provided with filter layer 7 on the housing 1, and pressure distribution 6 chambeies connect compressed gas source and vacuum extractor.Housing 1 is provided with inlet point 2 and discharging opening 3, and pressure distribution chamber 6 is arranged between inlet point 2 and the discharging opening 3.Because pressure distribution chamber 6 communicates with the inner chamber of housing 1, and pressure distribution chamber 6 connects vacuum extractor, vacuum means is set to vacuum pump, then the air that is mingled with in the powder material can be extracted out, so that form vacuum in housing 1 inner chamber, this is just so that the increasing of the proportion of powder material, volume-diminished, be convenient to carry, because the outside of some air extractor vents 11 is provided with filter layer 7 on the housing 1, can guarantee in the process that vacuumizes, powder material can not extracted out, thereby the utility model can be finished the transportation work of the little powder material of proportion efficiently, and can not produce the phenomenon of flour dust overflow, namely protect environment to reduce again waste, for enterprise has reduced productive costs; Because pressure distribution chamber 6 also connects compressed gas source, can switch easily and fast the dual mode of bleeding and blow again, finish efficiently the blowback rapping work to filter layer 7, guarantee the work efficiency of pay-off.
Filter layer 7 comprises filter screen 71 and is used for filter screen 71 is pressed in orifice plate 70 on the housing 1.Orifice plate 70 can play the effect of protection filter screen 71, prevents that filter screen 71 is out of shape under the effect of gas, affects filter effect; prolonged the service life of filter screen 71; reduce the replacing number of times of filter screen 71, reduced the operating cost of pay-off, and further improved work efficiency.
Pressure distribution chamber 6 connects compressed gas source and vacuum extractor by connection pipe 5, one end of connection pipe 5 is connected with extraction pipe 8 and gas blow pipe 9 simultaneously, extraction pipe 8 connects vacuum extractor, and gas blow pipe 9 connects compressed gas source, is equipped with shutoff valve 10 on extraction pipe 8 and the gas blow pipe 9.Can switch very easily and vacuumize and to the blowback rapping work of filter screen 71, but actv. prevents the obstruction of filter screen 71, has guaranteed the work efficiency of pay-off.
Principle of work of the present utility model: during conducting powder body mass transport, shutoff valve 10 on the gas blow pipe 9 is closed, shutoff valve 10 on the extraction pipe 8 is opened, the work that can when powder material is carried, vacuumize, increase the proportion of powder material, dwindle the volume of powder material, can finish efficiently the transportation work of powder material; When needs carry out cleaning to filter screen 71, shutoff valve 10 on the extraction pipe 8 is closed, shutoff valve 10 on the gas blow pipe 9 is opened, row cleans during to filter screen, for the better effects if of cleaning, the opening and closing that the shutoff valve 10 on the extraction pipe 8 and shutoff valve 10 on the gas blow pipe 9 can be replaced repeatedly, the repeatedly rapping that filter screen 71 is bled and blown, guarantee the unimpeded of filter screen, thereby guarantee work efficiency of the present utility model and quality.
