The conveying pipeline comprises a main pipe, wherein the main pipe is connected with the air source and allows air flow to be conveyed from front to back, and the main pipe is connected with at least one branch pipe. The powder conveying device further comprises discharge ports and material bins communicated with the corresponding branch pipes, and first valves corresponding to the upstream portions of the material bins are arranged on the material conveying pipeline. When the powder conveying device is used, the air source supplies air flow to the main pipe of the conveying pipeline, after powder enters the corresponding branch pipes through the material bins, the air flow drives the powder to be conveyed in the conveying pipeline, and therefore no corresponding mechanical transmission relation is needed, noise of the powder conveying device is reduced, the probability that the powder is contaminated in the conveying process is lowered, and the maintenance rate of the whole device is decreased.
Description
Technical field
The utility model relates to the powder-material conveying equipment in oil-filed fracturing propping agent production process.
Background technology
Fracturing propping agents are a kind of ceramic particle products, taking fine aluminum alumina as primary raw material is after fragmentation is finely ground into micro mist, are equipped with various additives, mixing, granulation repeatedly, polishing, high temperature sintering form, it is high that this product has compressive resistance, and density is low, and sphericity is good, highly polished, the advantages such as flow conductivity is strong, have very high pressure break intensity, are mainly used in oil field well and support, to increase the output of petroleum gas, belong to environment-friendly products.When petroleum gas deep mining, high closing pressure deposits of low permeability, after fracture treatment, splits Oil gas-containing rock layer, the passage that oil gas forms from crack, collects.Enter Filling in rock crack with high-pressure solution with haydite propping material, play support crack not stress discharge and closed effect, thereby keep high flow conductivity, make oil gas unimpeded, increase output.
Powder-material conveying equipment is the visual plant in fracturing propping agents manufacturing process, aluminium sail soil will be delivered in corresponding granulation pot and granulate through powder-material conveying equipment after waiting primary raw material to be ground into powder, powder-material conveying equipment is in the past conveyor screw or load-transfer device etc., load-transfer device easily produces airborne dust in course of conveying, conveyor screw is unfavorable for long distance conveying, no matter be conveyor screw or load-transfer device in addition, whole powder-material conveying equipment is because mechanical drive all can produce larger noise; It is contaminated in course of conveying that the load transfer device of this mechanical transmission-type also easily causes powder in addition; Complicated mechanical drive also causes the maintenance rate of powder-material conveying equipment higher.
Summary of the invention
The purpose of this utility model is to provide a kind of powder-material conveying equipment, has the problem of larger noise to solve existing powder-material conveying equipment because of mechanical drive.
In order to address the above problem, the technical solution of the utility model is:
A kind of powder-material conveying equipment, comprise source of the gas and delivery duct, delivery duct comprises the supervisor who carries from front to back for air-flow for being connected with described source of the gas, on supervisor, be connected with at least one arm, powder-material conveying equipment also comprises discharging opening and the feed bin that corresponding arm is communicated with, and on feeding pipe, is equipped with the first valve in the provided upstream of corresponding feed bin.
Described feed bin is vertically arranged.
Between the discharging opening of described feed bin and corresponding arm, be provided with powder pumps.
Described source of the gas comprises the positive blowdown fan of the inflow point that is arranged at described supervisor.
Described arm has at least two.
Each arm is extended towards rear-inclined to exit end gradually by entrance point.
Each arm be arranged in parallel.
Described delivery duct also comprises the powder delivering pipe of carrying from front to back for powder, and the outlet of each arm is all connected with described powder delivering pipe.
On each arm, be provided with the second valve in the downstream of corresponding feed bin.
In described powder delivering pipe, be provided with the 3rd valve in the upstream of the exit end of each arm.
The beneficial effects of the utility model are: in use, source of the gas passes into air-flow in the supervisor of delivery duct, after in powder enters corresponding arm by feed bin, air-flow drives powder to carry in delivery duct, so just do not need corresponding mechanical drive relation, the noise that has reduced on the one hand powder-material conveying equipment, has also reduced powder contaminated possibility in course of conveying simultaneously, has also reduced the maintenance rate of whole equipment.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
Detailed description of the invention
A kind of embodiment of powder-material conveying equipment is as shown in Figure 1 and 2: comprise source of the gas, delivery duct and four feed bins 2, delivery duct comprises the supervisor 5 who carries from front to back for air-flow, and source of the gas comprises the positive blowdown fan 1 of the inflow point that is arranged at supervisor.Delivery duct also comprises powder delivering pipe 4 and four arms that be arranged in parallel carried from front to back for powder, the import of each arm is all communicated with supervisor, each arm by entrance point to exit end gradually towards rear-inclined, the outlet of each arm is all communicated with powder delivering pipe, each feed bin 2 is vertically arranged in respectively on corresponding each arm, and the discharging opening of each feed bin is communicated with corresponding arm by powder pumps 3 respectively.On each arm, be provided with the first valve 9 for break-make air-flow in the upstream of corresponding feed bin, on each arm, be provided with the second valve 8 for break-make powder and air-flow in the downstream of corresponding feed bin, the second valve is push-pull valve, in powder delivering pipe, being provided with the 3rd valve 6, the three valves in the exit end upstream of each arm is push-pull valve.
In the time of concrete use, positive blowdown fan provides air-flow for load transfer device, can realize by the break-make of each valve that single arm is carried or plural arm is carried oil-filed fracturing propping agent powder simultaneously, four arms are respectively the first arm 7-1, the second arm 7-2, the 3rd arm 7-3 and the 4th arm 7-4, in the time only needing to use the 4th arm, close first, the second and the 3rd the first valve and the second valve on arm, stopping due to the first valve like this, air-flow just can not flow through first, second and the 3rd arm, close correspondence the 3rd valve in powder delivering pipe simultaneously, the powder that prevents powder delivering pipe upstream mixes with the powder in the 4th arm, so just realize the use of single arm, in the time that needs manifold uses simultaneously, can realize by controlling corresponding valve break-make.
In other embodiment of the present utility model: each the second valve and the 3rd valve can also not established; Powder pumps also can not established, and now powder can rely on gravity to be entered in corresponding arm by feed bin; The number of arm and feed bin can also be one, two, three, five or other number; Powder delivering pipe can also not established, and now powder is directly carried backward by each arm; Positive blowdown fan can also be arranged on other sources of the gas such as the negative-pressure air fan of the exit end of delivery duct and replace; The number of each arm feeding bin can also be two, three or more; Each arm also can not parallelly arrange.
