Description
Technical field
The invention belongs to Architectural Equipment field, particularly a kind of powder-granule material malleation transmission pump.
Background technology
In construction trade, often use powdery or granular material, such as cement, sand etc., these material requires and other materials carry out hybrid process, the building or ornament materials that can meet building engineering needs can be combined to form, in the conveying course of processing, artificial or vehicle was all adopted to transport in the past, its traffic cost is high, transport efficiency is low, so, in order to realize mechanization and the automation of building operation, people carry powdery or granular material with regard to adopting blast system, this conveying is the wind utilizing blower fan to produce, by powdery or granular material by Cemented filling to destination, transport efficiency is high, and the requirement that can meet toward eminence conveying, its principle is that the wind that blower fan produces forms air-flow in the duct, pipeline arranges a reducing, namely reduce suddenly its ventilation diameter at this segment pipe, at minor diameter place, powdery or granular material feed opening are set, due to airflow function, accelerate at small sized pipeline one end air-flow, to forming certain negative pressure around tube wall, relying on deadweight to flow out from bin outlet powdery or granular material, being then transported to destination with air-flow along pipeline, wind is adopted to pass through in journey at powder-granule material, when the powder-granule material density be transferred is less, the powder-granule material material that density more particularly as granular polystyrene one class is little especially, the negative pressure that air-flow is formed and powder-granule material are conducted oneself with dignity when can not overcome air-flow to friction force between the pressure of tube wall and powder-granule material and between powder-granule material and discharging opening, air-flow can produce supporting power to powder-granule material, now, powder-granule material just can not rely on deadweight to flow out from feed bin discharge hole, even if flow out, its discharge is also very little, have a strong impact on wind and send efficiency, wind even can not adopted to deliver to and to reach the object of carrying powder-granule material.
Summary of the invention
The above problem existed when carrying for the material that density is less for existing powder-granule material blast system, the present invention proposes a kind of powder-granule material malleation transmission pump, it is characterized in that: comprise conveyor screw, inlet point, removable cover door, housing, discharging opening, ventilation inlet, airduct, blower fan; Described conveyor screw is arranged on housing rear end top, and described conveyor screw discharging opening is connected with inlet point; Described inlet point is arranged on housing rear end top, is connected with conveyor screw discharging opening; Described inlet point is the cavity body having certain length, and its inner chamber is tapered, and in it, end cross-sectional area is less than outer end cross-sectional area; Described removable cover door is arranged on inlet point inner end, its upper end and inlet point upper articulation, and the area of removable cover door is greater than inlet point sectional area, and when freely hanging down, inlet point can cover by removable cover door completely; Described removable cover door can freely swing around hinged place; Described housing is taper or half cone cavity body, and front end is provided with discharging opening, and rear end is provided with ventilation inlet and inlet point, and its discharging opening one end cross-sectional area is little, ventilation inlet and inlet point one end cross-sectional area large; Described discharging opening is positioned at housing forward end, is connected with the delivery duct of blast system; Described ventilation inlet is arranged on rear end lower, is connected with airduct; Described airduct one end is connected with ventilation inlet, and the other end is connected with fan outlet.
Beneficial effect
Beneficial effect of the present invention is, the wind that can realize light powder pellet send conveying, and powder-granule material conveying is reliable, and efficiency is high, saves the energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
1. conveyor screw, 2. inlet point, 3. removable cover door, 4. housing, 5. discharging opening, 6. ventilation inlet, 7. airduct, 8. blower fan.
Detailed description of the invention
In order to further illustrate technical scheme of the present invention, existing accompanying drawings the specific embodiment of the present invention, as Fig. 1, select the powder-granule material conveyor screw that the industry of discharging opening diameter 200 millimeters is general, as conveyor screw 1, the steel plate of thickness 3 millimeters is selected to make outer diameter 200 millimeters, inner diameter 160 millimeters, the tapered tubular that length is 300 millimeters, as inlet point 2, attach it to the top of housing 4, inner thickness setting 5 millimeters, the lid door of diameter 200 millimeters, the top of Gai Men top and inlet point 2 adopts hinge, as removable cover door 3, select the steel plate of thickness 3 millimeters, be made into tail end diameter 1000 millimeters, point diameter 500 millimeters, the inclined conical cavity body of length 1000 millimeters, its underpart is set to straight, and upper angled is as housing 4, the discharging opening 5 of 300 mm diameter is set in the front end of housing 4, and is connected with powder-granule material delivery duct, the ventilation inlet 6 that diameter 150 millimeter be set concordant with bottom in its tail end bottom, and be connected with airduct 7, select air supply duct that the industry of diameter 150 millimeters is general as airduct 7, according to the installation site of blower fan 8, choose corresponding length, be connected its one end with ventilation inlet 6, the other end is connected with the air outlet of blower fan 8, the centrifugal blower selecting the industry general or roots blower are as blower fan 8, conveyor screw 1 is arranged on housing 4 tail end, its discharging opening is connected with the inlet point 2 on housing 4, just complete enforcement of the present invention, during application, powder and granule shape material enters in conveyor screw 1 from the feed bin of conveyor screw 1, by the effect of feedway, be transported to inlet point 2 inner, because inlet point 2 has certain length, and be pyramidal structure, powder-granule material can be deposited in inlet point, the wind of blower fan 8 output in housing 4 is played and closes wind effect, be equivalent to the general effect of closing air-valve, simultaneously due to the effect of removable cover door 3, when the material thrust blast that be less than housing 4 in of removable cover door 3 in inlet point 2 adds the deadweight of upper cover door, removable cover door 3 can cover and play sealing process at the inner end of inner end to inlet point 2 of inlet point 2, therefore material can not form refluence because blast is large, when the delivery pressure of conveyor screw 1 is greater than the deadweight of blast in housing 4 and removable cover door 3, removable cover door 3 backs down by material, and material enters in housing 4, is sent under wind-force effect from discharging opening 5, because housing 4 is tilted conicals, material can not form dead angle and pile up in housing 4, like this, use identical air quantity, just can carry more material, test proves, adopts this kind of carrying method except avoiding light material to be held up except the problem that can not carry, carries same material, power 40% can be saved, save the energy, improve production efficiency.
