Description
Technical field
The utility model belongs to powder carry field, is related to a kind of metering system.
Background technology
Pneumatic transmission groove is widely used to concrete at present as the powder-material conveying equipment that a kind of transfer efficiency is high, energy consumption is small
On mixing plant, for powder carries such as cement, flyash, miberal powders, a kind of powder material air conveying for being provided such as this applicant and
Metering device, Authorization Notice No. CN201907856U, it is characterised in that：Claim including powder cabin, powder and claim arranged on the powder cabin and powder
Between conveying skewed slot, the lower part of the conveying skewed slot is connected with air channel, and the conveying skewed slot and the junction of the air channel are equipped with
Ventilation filter cloth, the air channel is interior to be equipped with some gas nozzles of the opening towards the conveying skewed slot, which is all connected to high pressure gas
On source；The junction that the conveying skewed slot claims with the powder is equipped with control valve, and the control valve and the controlling switch of the high-pressure air source link
Connection.Since mixing plant actual production needs to use some a small amount of powders, such as miberal powder, powdered additive in, due to
Amount is seldom, more difficult control conveying capacity in course of conveying, and if ensureing measuring accuracy using the less powder pneumatic transmission groove of flow,
's the powder metering time can then lengthened so as to influence the production efficiency of mixing plant, therefore the applicant proposes following improve.
Utility model content
To overcome deficiency of the prior art, the utility model provides a kind of metering system, solves existing powder
When conveying device conveys a small amount of powder, in course of conveying the problem of more difficult control conveying capacity.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of metering system, including powder pneumatic transmission groove and metering device, the powder pneumatic transmission groove and metering device pass through defeated
Pipe is sent to connect, it is characterised in that：Screw conveyor is further included, the screw conveyor input terminal is provided with to be connected with powder pneumatic transmission groove
Logical storage bin, the screw conveyor output terminal are connected with delivery pipe, are arranged to when powder pneumatic transmission groove is conveyed to metering device
Material close to target weight when, powder pneumatic transmission groove stops conveying, and screw conveyor is by the material in storage bin to metering device
Conveying is until the material of metering device reaches target weight.
Further, screw conveyor is arranged in below powder pneumatic transmission groove.
Further, storage bin is arranged close to delivery pipe.
Further, screw conveyor housing inner cavity is pipe with small pipe diameter.
Further, screw rod and helical blade are equipped with screw conveyor housing.
Further, driving device is further included, the driving device is connected with the screw rod to drive screw rod to rotate
Movement conveying powder.
Further, driving device includes driving motor.
Further, the valve of control break-make is equipped between metering device and delivery pipe connection.
From the above description of the utility model, it can be seen, compared with prior art, a kind of metering system of the utility model,
When the powder for entering powder metering bucket body reaches default thick metering setting value, powder pneumatic transmission groove stops feeding, by spiral transferring
Machine is sent to start feeding to metering device, after metering desired value is reached, screw conveyor stops, and control valve is closed, and has been measured
Into, it is simple in structure, it is easy to operate, while powder carry efficiency is met, delivery precision is also can guarantee that, when shortening powder metering
Between, improve production efficiency.
