A kind of device that discontinuous charging is become continuously even charging
Technical field
The utility model relates to the automatic packaging machinery field of food processing, especially about a kind of device that discontinuous charging is become continuously even charging in negative pressure material loading metering outfit.
Background technology
Negative pressure material loading in domestic and international most of gas negative pressure transportation metering outfit all is to carry out the suction conveying with manually holding material sucking mouth at present, material loading mainly is to carry particle, powder material, this mode suction is random, discontinuous suction, the problem of bringing thus is that the amount of suction can't be measured with the suction amount of unit time, can only add the weighting apparatus metering in storage silo, but because it is many a little while few a little while to enter the material of storage silo, it is very big to fluctuate, also very low with the weighting apparatus measuring accuracy, can not be used for accurate measurement, therefore can only after suction, add a kind of device and make random, charging is uniformly continuously changed in discontinuous charging.
Summary of the invention
There is random, the discontinuous problem of suction in order to solve with artificial suction with negative pressure (vacuum) suction equipment, the purpose of this utility model is to provide a kind of fairly simple device, sucking with negative pressure in the delivery pipe is the mixture of gas and material, can utilize a kind of device first with gas and feed separation with gas and feed separation, treat then to be mixed into continuously mixture uniformly again with gas again after the certain amount of material storage, enter into the storage silo of back.
The technical solution of the utility model realizes in the following manner: a kind of device that discontinuous charging is become continuously even charging, form by suction tube, connection pipe, storage silo, negative pressure generation equipment etc., the top of storage silo is connected with negative pressure generation equipment by connection pipe, top is provided with inlet point, be connected with feed pipe, it is characterized in that: be provided with the separation buffer storehouse between described feed pipe and the suction tube.
The top in described separation buffer storehouse is provided with inlet point, and top is provided with gas feed.
The top in described separation buffer storehouse is provided with gas feed, and top is provided with inlet point.
Adopt the utility model structure, random, discontinuous material with artificial suction can be become and expect uniformly continuously to enter storage silo, can utilize the amount of the convey materials in the control unit time or use suitable flow counter to carry out the amount of accurate measurement convey materials.Also can add the weighting apparatus metering in the storage silo of back,, weighing precision is greatly improved, reach user's requirement because the fluctuation of charging uniformly is little continuously.

Fig. 1 is embodiment 1 structural representation of the present utility model.
Fig. 2 is embodiment 2 structural representations of the present utility model.
The specific embodiment
Know by Fig. 1, it is the structural representation of present embodiment 1, form by suction tube 2, connection pipe 9, storage silo 8, negative pressure generation equipment 9 etc., the top of storage silo 8 produces equipment 10 by connection pipe 9 and negative pressure and is connected, the top of storage silo 8 is provided with inlet point 7, be provided with separation buffer storehouse 5 between described feed pipe 2 and the suction tube 2, the top in separation buffer storehouse 5 is provided with inlet point 4, and top is provided with gas feed 3.
Being known by Fig. 2, is the structural representation of present embodiment 2, and the top in separation buffer storehouse 5 is provided with gas feed 3, and top is provided with inlet point 4.
The principle of work in separation buffer storehouse is described with the negative pressure charging equipment below:
Negative pressure produces equipment (as high pressure positive blower, vacuum pump etc.) after 10 work, make storage silo by connection pipe 9, produce negative pressure in the belongings materials flow roads such as connection pipe, under suction function, draw material with manually holding material sucking mouth 1, the material of drawing enters separation buffer storehouse 5 via suction tube 2 and inlet point 4, effect through gravity or cyclonic separation, material drops to the bottom in separation buffer storehouse 5, gas then leads to material outlet 6 through gas vent 3 along connecting tube, the material that flows down with separation buffer storehouse 5 mixes again, and the openings of sizes of the material outlet 6 of 5 bottoms, separation buffer storehouse is adjustable, be transferred to suitable when big or small, when promptly inlet amount is a bit larger tham load, material in the separation buffer storehouse 5 slowly heap is high, when being stacked into certain height, accelerate in the effect bottom discharge amount that material is pressed, form dynamical equilibrium with inlet amount.The material that flow down from separation buffer storehouse 5 this moment is continuous, and gas also is continuous when flowing to material outlet 6, just formed continuously uniform mixture after the mixing, inlet point 7 through storage silo 8 enters storage silo 8, because the charging of this moment is uniform, materials flow amount in unit time is a fixed value, just can reach the amount of control convey materials by the control feed time; Also can use suitable flow counter to carry out the amount of accurate measurement convey materials.
