Metering dust suppression device for grain loading

Abstract

The invention provides a metering dust suppression device for grain loading. A discharge port of a granary communicates with a feed port of a metering device through a pipeline; a manual gate is arranged on the discharge port of the granary; the metering device is a chute scale; a discharge port of the metering device is connected with a feed port of a dust suppression device through a pipeline; the metering device and the dust suppression device are fixedly connected to a supporting platform; a loading position of a grain transfer vehicle is arranged below the supporting platform; a discharging port in the lower end of the dust suppression device corresponds to the loading position of the grain transfer vehicle; and a pneumatic gate is arranged on the discharging port of the dust suppression device. According to the metering dust suppression device for grain loading, by using the metering device to weigh the weight of loaded grains, the situations of overloading and less loading are reduced, the trouble of back-and-forth weighing of a vehicle is avoided, the use cost of machinery and manpower is reduced, and the overall loading efficiency of a silo is improved; and through the dust removal device, the situation of dust overflow in the loading process can be reduced, raise dust can be reduced, dust diffusion in a working place can be avoided, and a good working environment is provided for operators.

Description

Technical field: [0001] The invention belongs to the technical field of grain transfer equipment, and in particular relates to a metering and dust suppression device for loading grain out of a grain silo. Background technique: [0002] At present, in the process of grain transshipment, during the process of loading grain out of the warehouse from wharfs, granaries and other places, the bulk grain mainly falls quickly from the ship or granary to the transport vehicle through the self-flow of silos. The dust and light impurities will float into the air, and the grain materials will be sheared with the air during the falling process. The high-speed airflow extruded by the grain materials will carry the dust and light impurities, and a large amount of dust will spread to the air. In the surrounding environment, due to the small dust particles, light weight, and slow sedimentation speed, the grain loading and transshipment site remains dusty for a long time, which is harmful to t...

Problems solved by technology

[0002] At present, in the process of grain transshipment, during the loading process of grain from wharfs, granaries and other places, the bulk grain mainly falls quickly from the ship or granary to the transport vehicle through the self-flow of silos. The dust and light impurities will be scattered into the air, and the grain materials will be sheared with the air during the falling process. The high-speed airflow extruded by the grain materials will carry the dust and light impurities, and a large amount of dust will spread to the air. In the surrounding environment, due to the small dust particles, light weight, and slow sedimentation speed, the grain loading and transshipment site remains full of dust for a long time, which is harmful to the health of the loading workers and pollutes the atmospheric environment.

[0003] In addition, when the bulk grain slides from the ship or granary to the transport vehicle through the self-flow of the silo, its flow rate cannot be measured, so the weight of the loaded grain cannot be measured, and the phenomenon of over-loading or under-loading often occurs, resulting in transportation Vehicles often weigh back and forth, resulting in low loading efficiency and higher loading costs
