Multi-stage feeding equipment for conveying particle materials

Abstract

The invention relates to multi-stage feeding equipment for conveying particle materials. The multi-stage feeding equipment for conveying the particle materials comprises a first-stage material tank, adust remover arranged at the top of the first-stage material tank as well as a hopper arranged on the lower side of the first-stage material tank; an upper level gage is arranged on the upper part ofthe first-stage material tank; a plurality of weighing sensors which are distributed uniformly and circumferentially are arranged on the middle part of the first-stage material tank; a lower level gage is arranged on the lower part of the first-stage material tank; a plurality of uniformly distributed gas hammers are arranged on the hopper; a disk feeder is arranged at the lower end of the hopper; the lower end of the disk feeder is connected with two or more than two material distributing pipes; a first transmission mechanism is arranged at the lower end of the disk feeder; and a pneumatic butterfly valve positioned above the material distributing pipes is arranged at the lower end of the disk feeder. The multi-stage feeding equipment for conveying the particle materials can automatically detect the bridging condition, can eliminate the bridge at the first time of detecting the bridging condition, and can realize an automatic loading function and improve the feeding efficiency.

Description

technical field [0001] The invention relates to a feeding device, in particular to a multi-stage feeding device for conveying granular materials. Background technique [0002] Feeding equipment is a device used to transport materials. Due to the characteristics of granular materials, when the granular materials enter the material tank of the feeding equipment and are ready to be unloaded, it is very easy for the granular material to bridge, that is, to form in the material tank. Once the bridging occurs in the cavity, the material on the upper part of the cavity cannot be discharged through the disc, which will affect the stability of the conveying of the granular material. In order to solve the above problems, a stirring device is generally used to continuously stir the granular material. In order to avoid the situation of bridging, and the non-stop stirring of the stirring device needs to rely on the driving motor that has been running all the time. The energy consumption ...

[0002] Feeding equipment is a device used to transport materials. Due to the characteristics of granular materials, when the granular materials enter the material tank of the feeding equipment and are ready to be unloaded, it is very easy for the granular material to bridge, that is, to form in the material tank. Once the bridging occurs in the cavity, the material on the upper part of the cavity cannot be discharged through the disc, which will affect the stability of the conveying of the granular material. In order to solve the above problems, a stirring device is generally used to continuously stir the granular material. In order to avoid the situation of bridging, and the non-stop stirring of the stirring device needs to rely on the driving motor that has been running all the time. The energy consumption of stirring a large amount of materials is huge, and the driving motor is easily damaged under long-term operation. , which seriously shortens the service life. If the stirring device is operated at intervals, a separate drive motor is required, and timely and accurate damage to the bridge cannot be guaranteed, which may cause the feeding to be unstable.

[0003] In the actual operation process, when using single-stage feeding equipment, due to the limitation of material storage capacity, it is necessary to carry out frequent feeding operations in the silo, which may easily cause feeding interruptions or measurement fluctuations; and frequent operations increase the probability of dust leakage, and the operating environment and its bad

If it is necessary to feed multiple locations at the same time, each feeding location needs to be equipped with a storage tank and corresponding feeding equipment, resulting in extremely high feeding costs and extremely inconvenient management

[0004] In order to avoid frequent replenishment and feeding, the feeding equipment is usually equipped with a large storage tank, and the top of the tank is at a relatively high position, which requires the staff to climb high to carry out the feeding work, which has certain safety hazards and the efficiency of manual feeding is low.
