Description

Cement bulk quantitative feeding device

Technical Field

The utility model belongs to the technical field of cement quantitative feeding, and particularly relates to a cement bulk quantitative feeding device.

Background

Cement bins are commonly used in concrete mixing plants, and are closed tanks for storing bulk cement, which are provided with a material level system capable of displaying the position and quantity of materials. When feeding to the cement tank truck, the material is conveyed to a feeding pipeline through a screw conveying pump and then discharged to a cement tank on the cement tank truck, so that one-time feeding operation is completed.

At present, the quantity of cement discharged is generally controlled by a pneumatic valve and a flow valve, so that the quantity of bulk powder is not accurate enough, the phenomenon of multiple loading or fewer loading is easy to occur, the high speed is not realized when the bulk powder is loaded in an overload way, the number of times of transporting goods is required to be increased, and the freight cost is increased, therefore, in order to solve the problems, the cement bulk quantitative feeding device is provided.

Disclosure of Invention

The utility model aims at: in order to solve the above-mentioned problems, a cement bulk dosing device is provided.

The technical scheme adopted by the utility model is as follows: the cement bulk quantitative feeding device comprises a cement bin, wherein a discharge hole of the cement bin is communicated with a feeding pipeline, the bottom end of the feeding pipeline is connected with a quantitative shell, and a punching flowmeter is arranged in the quantitative shell;

the pneumatic valve is assembled on the upper side of the feeding pipeline through a connecting flange.

In a preferred embodiment, the underside of the pneumatic valve is fixedly connected to the feed line via a flange to a flow valve.

In a preferred embodiment, a console is fixedly arranged on one side of the cement bin, and the console is electrically connected with the flow valve, the flushing plate flowmeter and the pneumatic valve.

In a preferred embodiment, the flushing plate in the flushing plate flowmeter is located directly below the discharge side of the feed pipe.

In a preferred embodiment, the discharging end at the bottom of the quantitative shell is connected with a telescopic cloth bag.

In a preferred embodiment, the console is equipped with a touch screen.

In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:

according to the utility model, the control console is provided with the materials which are quantitatively discharged once, the pneumatic valve is opened during feeding, then discharging is started, the discharged cement is metered by using the impact plate flowmeter in the discharging process, the flow is accumulated by using the control console, once the pneumatic valve is closed after the set flow is reached, once quantitative feeding operation can be completed, the PLC program control is utilized, the loading error is small, and the frequent operation problems of overfilling, ash leakage, insufficient multiple loading and the like of the previous loading are avoided.
