Sending device for material pneumatic conveying system

Abstract

The invention discloses a sending device for a material pneumatic conveying system. The sending device comprises a machine frame, wherein a sending station is arranged in the machine frame; the sending station is provided with a vertical sending pipeline for communicating with a pneumatic conveying pipeline; a sample feeding notch is formed in the side wall of the lower end of the sending pipelineso that an object to be conveyed can be placed at the sending station; and a sample feeding door matched with the sample feeding notch is further arranged, so that the sample feeding notch is sealedafter the sample feeding door is closed so as to carry out pneumatic sending. The sending device for the material pneumatic conveying system has the advantages of being simple and compact in structure, convenient and flexible to operate, high in working efficiency and intelligent degree.

Description

technical field [0001] The invention mainly relates to the field of equipment for collecting and processing material samples, and in particular to a sending device for a material pneumatic conveying system. Background technique [0002] For the sampling, sample preparation, and testing of material (such as ore, coal) samples, each country has mandatory standards, and the sampling and processing of samples must be carried out in accordance with the standards. The principle of sample sampling, sample preparation, and testing work process is to gradually reduce the particle size and quality of the collected samples without destroying the representativeness of the sample, until it meets the particle size and quality of the sample in the laboratory test ( Weight) accuracy requirements, and then carry out relevant laboratory analysis on the samples that meet the requirements. [0003] For example, taking coal sampling as an example, it is actually a sampling and analysis process....

AI Technical Summary

Problems solved by technology

[0005] (1) The existing technology adopts the lifting method to push the object (sample bottle) into the pneumatic pipeline or lowers the conveying pipe to cover the object (sample bottle) by lifting method, which makes the control complicated, the sealing requirement is high, and it is easy to appear Fault

[0006] (2) The existing technology adopts the lifting method, and the bottom or upper part of the sending station needs to be reserved for lifting and displacement space, and the airborne requirements are large, resulting in a generally large sending station

[0007] (3) In the prior art, the sample bottle needs mechanism control from the placing station to the sending station, and the sending of the sample bottle on the sending station needs another lifting mechanism to place the sample bottle into the pipeline first, and the control is complicated

[0008] (4) There is no card reader at the bottom of the existing technology, and it is impossible to judge the code information of the object (sample bottle) to be transported, and the system cannot automatically send the sample bottle to which workstation

Unable to realize multi-point automatic transmission
