Problems solved by technology
[0003] However, there is also a significant problem—the four sampling probes are driven by bevel gears. In the case of running with powder, coal powder particles will accumulate between the driving and driven gears. The longer the rotation time, the accumulation more powder
When the powder is piled up between the two bevel gears, it will bring problems to the whole set of equipment: the gear jams and cannot rotate, the probe of the sampling gun is deflected, and the probe cannot be taken out from the sampling hole, etc.
[0004] In order to solve the powder jam problem of the bevel gear of the rotary sampling gun, the present invention proposes a dust-proof protection method and device for the bevel gear of the rotary sampling gun, which can protect the driving and driven gears from dust in the case of running with powder The pollution of coal powder improves the reliability and service life of the rotary sampling gun

The invention discloses a bevel gear dustproof protection method and a bevel gear dustproof protection device for a rotary sampling gun, which are used for solving the problem of powder blockage of abevel gear in the use process of the rotary sampling gun. The device comprises a sampling nozzle, a sampling pipe, a driving bevel gear, a driven bevel gear and a fixed seat, wherein a left protectivecover and a right protective cover are arranged on two sides of the fixed seat; the driving bevel gear is connected to a control box through a driving pipe, and a sealing ring is arranged on the driving pipe. According to the bevel gear dustproof protection device, under the condition that the bevel gear operates with powder, dustproof protection can be effectively conducted on the gear, the reliability of system operation is improved, and the service life of the system is prolonged.
Description
technical field [0001] The invention relates to a bevel gear dustproof protection method and device for a rotary sampling gun. Background technique [0002] The rotary sampling gun is a pulverized coal sampling gun recommended by the international standard ISO9931. It uses a rotary sampling probe. The four probes go deep into the pulverized coal pipeline through the sampling holes on the sampling pipeline. , that is, 4 probes take samples along 64 points on 4 equal sections, which has the advantage of high sampling representativeness. [0003] However, there is also a significant problem—the four sampling probes are driven by bevel gears. In the case of running with powder, coal powder particles will accumulate between the driving and driven gears. The longer the rotation time, the accumulation more powder. When the powder is piled up between the two bevel gears, it will bring problems to the whole set of equipment: the gear jams and cannot rotate, the probe of the samplin...
