Long-distance pneumatic conveying system for coal samples

Abstract

The invention provides a long-distance pneumatic transmission system for coal samples. The long-distance pneumatic transmission system for the coal samples comprises a fan power unit, a coal sample bottle temporary storage cabinet, conveying pipelines, a pipeline reverser and pneumatic sending stations; the fan power unit comprises a fan and a wind power reversing valve, air sucking and air blowing can be achieved, and power is provided for receiving and sending of coal sample bottles; the coal sample bottle temporary storage cabinet is provided with a coal sample bottle inlet and a coal sample bottle outlet, the coal sample bottle inlet is connected with a sampling area through the conveying pipelines, and the coal sample bottle outlet communicates with the pneumatic sending stations; and the fan power unit is connected with the conveying pipelines through the pipeline reverser, one conveying pipeline communicates with the coal sample bottle inlet to provide sucking force for receiving and sending of the coal sample bottles, the other conveying pipelines are correspondingly connected with the pneumatic sending stations respectively, and the other ends of the pneumatic sending stations are connected with workstations to distribute the coal sample bottles to the workstations for sample checking and testing. According to the long-distance pneumatic transmission system for the coal samples, fully-closed automatic conveying of the coal samples is realized, the conveying efficiency of the samples is improved, and the influence of manual intervention is reduced.

Description

technical field [0001] The invention relates to the technical field of coal-fired power generation, in particular to a long-distance pneumatic transmission system for coal samples. Background technique [0002] In power generation enterprises, there are generally laboratories, and the coal samples are tested every day to determine the quality and price of the coal samples. The existing coal sample transmission mainly relies on manual transmission. Since the coal sample storage place is relatively far away from the laboratory, various safety risks caused by human factors are prone to occur during the manual transmission process. It is completed by two people, which requires a lot of labor, high labor costs, and low efficiency. At the same time, the sample may be replaced by humans during the delivery process, which cannot guarantee the representativeness and reliability of the test samples. [0003] In view of the above reasons, a coal sample long-distance pneumatic transmis...

The existing coal sample transmission mainly relies on manual transmission. Since the coal sample storage place is relatively far away from the laboratory, various safety risks caused by human factors are prone to occur during the manual transmission process. It is done by two people, the workload is large, the labor cost is high, and the efficiency is low. At the same time, the sample may be replaced by humans during the delivery process, and the representativeness and reliability of the test sample cannot be guaranteed.
