Background technology
At present, China is in the commerical ready-mixed concrete production process, and the powder that uses in its production process adopts screw machine to carry the feeding system of powder mostly, and its system's production technology is simple, easy to operate, stability is strong, but there is following shortcoming: the one, the material loading process is longer, and production efficiency is low; The 2nd, transmission power is big, and energy dissipation is bigger; The 3rd, because the powder feedway exposes, powder is revealed and is easily caused environmental pollution.Also have part to use the air flume feeding, but be to use pressurized air as power, same transmission power is big, and the gas oil-containing is moisture, and enters the title bucket with powder, causes dust bigger, influences powder and carries effect.Day by day under the strict situation, this kind equipment does not more and more meet actual requirement at environmental demands.
Summary of the invention
The technical problem to be solved in the present invention is to overcome traditional powder to carry the drawback that exists, and a kind of transport efficiency height, powder conveyer simple in structure are provided.
For solving the problems of the technologies described above, the present invention includes filler bin, the filler bin bottom is communicated with delivery chute, the delivery chute afterbody is equipped with the discharging valve, its constructional feature be described delivery chute from feed end to the downward-sloping setting of discharge end, be provided with the ventilative interlayer that the powder that its inner chamber is divided into top is carried the air chamber of storehouse and bottom near its diapire in the delivery chute, be provided with a plurality of ventilation inlets at the delivery chute diapire, the delivery chute below is provided with the breather pipe that is communicated with air-supply arrangement, described ventilation inlet is communicated with by air inlet pipe with breather pipe, corresponding to being provided with the air inlet shock absorber above each ventilation inlet, described delivery chute tail end top is provided with ventilative filter bag in air chamber.
Described ventilative interlayer comprises the bracing frame that is supported on the delivery chute inwall, is equipped with wire net on the bracing frame, is equipped with the ventilative cloth of high strength on the wire net.
Described delivery chute is made up of top frid and bottom frid, and described high strength is ventilative to be arranged in up and down between the frid.
Described air inlet shock absorber is for being supported on the buffering dividing plate of ventilation inlet top by pillar stiffener.
Described air-supply arrangement is the whirlpool air pump.
Described air inlet pipe is provided with and regulates the valves.
Described delivery chute is made up of top frid and bottom frid, and described ventilative interlayer places up and down between the frid.
After adopting said structure, because delivery chute is carried the air chamber of storehouse and bottom by the powder that the interlayer of breathing freely is divided into top, powder is deposited in powder and carries in the storehouse, in sealed gas chamber, form blast by air-supply arrangement, the powder bottom that the ventilative interlayer stepless action of infiltrate is piled up in powder is carried the storehouse naturally, the accumulation that changes powder forms and suspends, and powder is evenly flowed to lower with air-flow, realizes the conveying of powder.On-bladed in this conveyer delivery chute, eliminated the friction heat of powder and helicallobe, reduced the temperature rise of powder, and simple in structure, and fault rate is low, can effectively reduce maintenance of equipment cost and cost of labor, transport efficiency height, continuous working per hour can be carried 150 tons of powders, and skewed slot is the totally-enclosed cavity structure, no dust leaks, and satisfies environmental demands.Simultaneously, energy consumption is low, power of fan 1.5KW, and contrast conveyor screw 18.5KW, separate unit can be saved 17KW, is applied to greatly to have reduced energy consumption in the actual production.
