Abstract

The utility model discloses a feeding device of a forming machine which is easy to measure and can avoid generating dust, which comprises a feeding belt (2) arranged adjacent to the lower opening (1) of a hopper, and the feeding belt (2) is driven by a frequency conversion motor. The feeding belt (2) rubs against the powder (4) at the lower opening (1) of the hopper for discharging and feeding. The feeding device of the forming machine is driven by the friction of the feeding belt to output the powder, which overcomes the dust pollution environment caused by the falling of the powder in the prior art; moreover, the feeding belt is driven by a frequency conversion motor, so the operation of the feeding belt can be set in advance according to the needs Speed, so that the output speed and output volume of the powder can be freely controlled, which ensures the stable material receiving of the molding machine, and improves the molding productivity and the qualification rate of the coke.

Description

Molding machine feeding device for easy metering and avoiding dust generation

technical field

The utility model belongs to the field of coke production, in particular to a feeding device of a forming machine. the

Background technique

The production principle of molded coke is to mix various non-caking coals and weakly caking coals in a certain proportion, and then make molded coke through molding and carbonization processes. The accurate proportioning of different raw materials plays a key role in the production of coke and the quality of coke. Therefore, in the production system of coke, the coke batching device must fully realize the above functions. Since most of the raw materials for coke production are powder materials, for powder materials, when the moisture content of the powder materials is greater than 7%, the powder materials are easy to gather, thereby forming swelling and blocking materials in the silo; When the specific gravity is less than 4%, the powder is prone to dust during transportation and falling, causing environmental pollution and waste of returned materials. In addition, the feeding method of the existing molding machine is that the mixed powder is discharged from the hopper under its own gravity. The lower port falls onto the conveyor, and is then sent into the molding machine by the conveyor. Therefore, the powder is more likely to generate dust during the falling process, and the amount or speed of each drop is difficult to control and cannot be measured.

Utility model content

Aiming at the above disadvantages, the utility model provides a molding machine feeding device which is easy to measure and can avoid generating dust. the

The utility model is realized through such a technical scheme: a feeding device of a forming machine that is easy to measure and can avoid generating dust, the feeding device includes a feeding belt that is arranged next to the lower mouth of the hopper, and the feeding belt is driven by a frequency conversion motor Driven, the feeding belt rubs against the powder at the lower opening of the hopper to realize discharging and feeding.

In order to carry out discharging and feeding better, the lower opening of the discharge hopper is provided with a side opening, and the direction of the opening is consistent with the running direction of the feeding belt.

Further, a weighing scale is set at the end of the feeding belt.

The distance between the metering scale and the lower opening of the hopper is greater than 1 meter to ensure accurate metering.

Due to the adoption of the above structure, the beneficial effects of the utility model are as follows: the feeding belt is arranged adjacent to the lower mouth of the hopper, and the powder is output by the friction of the feeding belt, which overcomes the dust pollution environment caused by the falling of the powder in the prior art; Moreover, the feeding belt is driven by a frequency conversion motor, so the running speed of the feeding belt can be set according to the needs, so as to freely control the output speed and output of the powder, ensuring the stable feeding of the molding machine, and improving the molding productivity and coke. The qualified rate; further, a metering scale is set at the end of the feeding belt to realize linkage with the feeding belt, so as to measure the receiving material of the molding machine, and it is easy to control the accurate ratio between different raw materials to ensure the stable production of the molding machine And the quality of coke is stable. the
