Abstract
The utility model belongs to a pneumatic solid particle sprayer in the technical field of mine safety. The sprayer is provided with a tubular feed pipe of which the left end is provided with an impeller chamber and the upper part is provided with an air inlet pipe and a hopper; the right lower lateral part of the impeller chamber is provided with a long pipe which is directly communicated with the lower part of the right front end of the feed pipe; a feed nozzle with a small opening is connected to the right end part of the feed pipe; a feeder of which the left end is provided with an impeller is installed in the feed pipe. When steam flow enters the impeller chamber, the feeder rotates to feed material, and the air current is blown in the feed nozzle through a blast pipe to spray out particles homogeneously. The sprayer can effectively utilize the existing underground wind power resource to serve as power without utilizing electricity, and obtain homogeneous spraying effect through blowing. The utility model has advantages of large scope of work, favorable security, convenient operation, small work intensity, homogeneous spraying, wide range of application, high raw material utilization factor, no waste, and high popularization and application value.
Description
Affiliated technical field
The utility model belongs to a kind of pneumatic solid particle dispenser of safety of coal mines technical field, and high-efficiency fireproof, fire proofing are effectively sprayed in places such as it can be under coal mine, harbour, dump, reaches coal piling body spontaneous combustion control and suppresses the effect of dust from flying.
Background technology
As everyone knows, under coal mine,, in air, reach finite concentration, just have the danger of blast if coal dust is kicked up; In addition, the deposit thickness of coal dust reaches 01mm approximately on the ground, also has the danger of blast.At present, some high-efficiency fireproofs, fire-retardant dust-suppressing material also can effectively suppress coal dust and fly upward, the generation of control coal-dust explosion and propagation accident thereof; But at present, the down-hole mainly adopts simple instruments of labour to carry out shedding of this fire prevention, fire proofing, this working method, and efficient is low, labour intensity is big, and that sheds is very inhomogeneous, and the raw material utilization is very insufficient, wastes also big; Shed difficulty again for some special positions, down-hole, can stay unsafe hidden danger.To this, also there is not good solution at present.
Summary of the invention
In order to solve the problem of shedding of fire prevention, fire proofing, the utility model provides a kind of pneumatic solid particle dispenser, this dispenser has compressed air now as power source with the down-hole, no longer electricity consumption, can thoroughly solve the inefficiency of shedding mode at present, labor degree intensity big, shed inhomogeneous, waste is big, easily stay the problem of hidden danger, it has highly application value.
The concrete scheme that its technical problem that solves the utility model adopts is: this dispenser comprises blast pipe (1), blade wheel chamber (2), hopper (5), feed pipe (7), feed appliance (8), ajutage (9) and feed nozzle (12) seven parts; This dispenser has the feed pipe (7) of a tubulose, the blade wheel chamber (2) of sealing around its left end connects, and a tubule that has control valve is installed on this blade wheel chamber top, is blast pipe (1) that it is the air intake passage of blade wheel chamber; Bottom right sidepiece in blade wheel chamber (2) connects long tube one, and the below of its straight-through feed pipe (7) right front ends is ajutage (9); In the left end top of feed pipe (7), big young uncovered hopper (5) down suitable for reading is installed, it is the bucket-shaped container of charge; Right part in feed pipe (7), a fixedly connected spraying material mouth (12) that is shrunk to osculum; Inside in feed pipe (7), a feed appliance support (10), its center are installed in its right, the right-hand member by central longitudinal axis (11) of sliding fit passes, the left end of central longitudinal axis (11), the right side wall that passes blade wheel chamber of sliding fit, in blade wheel chamber (2), with the vertical installation of impeller (3); When steam flow entered blade wheel chamber (7) through blast pipe (1), air-flow blew impeller (3) on the one hand, made central longitudinal axis (11) and feed appliance (8) rotate feeding; On the other hand, air-flow is blown into feed nozzle (12) particulate material is sprayed away uniformly through ajutage (9).
Its beneficial effect is: this pneumatic solid particle dispenser, can effectively utilize the existing wind resource in down-hole as power, no longer electricity consumption, promptly can reach the effect of even spraying by the winding-up of air-flow, its job area is big, by the two ends connecting pipe, promptly can in being the zone of 50m, radius spray operation; Its security is good, and is easy to operate, and labour intensity is little; Spray evenly, applied widely, the raw material availability height is not wasted, and it has highly application value.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples;
Accompanying drawing is a structural principle schematic diagram of the present utility model;
Among the figure, 1 blast pipe, 2 blade wheel chamber, 3 impellers, 4 feeding channels, 5 hoppers, 6 control panels, 7 feed pipes, 8 feed appliances, 9 ajutages, 10 feed appliance supports, 11 central longitudinal axis, 12 feed nozzles.
The specific embodiment
In the drawings, hopper (5) is a funnel shaped that opens wide, and tabular control panel of twitching (6) of the installation of its lower horizontal sprays the spraying amount of expecting with control hopper (5) lining.
In the drawings, the center of feed appliance (8) is a long central longitudinal axis (11), and the left end of this major axis passes the bottom right sidewall of impeller (2), the vertical impeller that blowing is installed (3), the right-hand member sliding fit of its central longitudinal axis pass feed appliance support (10); On the central longitudinal axis (11) between the right side wall of feed appliance support (10) and blade wheel chamber (2), spiral plate is installed, this plate can play the effect that pushes material to feed nozzle.
Claims (2)
1. pneumatic solid particle dispenser, this dispenser comprise blast pipe (1), blade wheel chamber (2), hopper (5), feed pipe (7), feed appliance (8), ajutage (9) and feed nozzle (12) seven parts; It is characterized in that: this dispenser has the feed pipe (7) of a tubulose, the blade wheel chamber (2) of sealing around its left end connects, and a tubule that has control valve is installed on this blade wheel chamber top, is blast pipe (1); Bottom right sidepiece in blade wheel chamber (2) connects long tube one, and the below of its straight-through feed pipe (7) right front ends is ajutage (9); In the left end top of feed pipe (7), big young uncovered hopper (5) down suitable for reading is installed; Right part in feed pipe (7), a fixedly connected feed nozzle (12) that is shrunk to osculum.
