specific Embodiment approach

[0042] The Ω briquette transfer mechanical device includes a dust cover 1, a tapered funnel 2, an arc tee 3 and an Ω-shaped double drop pipe. The coal transported from the upstream first enters the dustproof cover 1, the function of the dustproof cover 1 is to prevent the coal dust, and then enters the throat drop coal funnel 2, and the coal in the throat drop coal funnel 2 is simply accumulated and mixed, and then flows into the arc In the shape tee 3, through the material distribution and diversion of the arc tee 3, it enters the two streamlined branch pipes of the Ω-shaped double drop pipe 4 respectively, and finally flows into the downstream conveying device.

[0043] The dust cover 1 does not bear any force, but only plays a dust-proof role. There is no specific requirement for the structure. The material is made of plastic PVC. Funnel 2 is connected.

[0044] Described conical funnel 2 is circular frustum structure, and material selects bimetal composite plate, has the ...

Abstract

The invention discloses an omega-shaped coal dropping pipe coal conveying system with a high-frequency vibration device. The omega-shaped coal dropping pipe coal conveying system comprises at least one inclined coal dropping pipe and further comprises pressure sensors and the high-frequency vibration device. The pressure sensors are arranged on the pipe walls of the coal dropping pipes. The high-frequency vibration device is in contact with the coal dropping pipes. A server is further included. The pressure sensors and the high-frequency vibration device are connected with the server. The omega-shaped coal dropping pipes are symmetrically arranged, and each coal dropping pipe segment is formed by splicing two arc-shaped pipes and a straight pipe. The good discharging property is achieved, coal briquette blocking can be avoided through a curved flow channel, the colliding angle of coal briquettes and the pipe walls is reduced, and generation and dissipation of dust are reduced. An arc-shaped tee joint and the straight pipe segments of the coal dropping pipes are all connected with the high-frequency vibration device. When the pipes are blocked seriously by coal in the pipes, the high-frequency vibration device is started through the pressure sensors, the arc-shaped tee joint and the middle segments of the omega-shaped double coal dropping pipes are driven to vibrate, and the functions of dredging and blocking preventing are achieved.

Description

technical field [0001] The invention relates to a coal conveying pipeline system, especially an Ω-shaped coal conveying system with a high-frequency vibration device, which can effectively prevent coal blockage and dust, has strong circulation, and belongs to the power plant conveying system. Transformation and environmental protection technology. Background technique [0002] Coal-fired thermal power generation has always been the main form of power generation in my country due to the current situation of China's resources rich in coal, poor in oil, and low in gas. In coal-fired power plants, coal transportation technology has always been an important link in power plant transportation technology, and the coal transfer link plays a vital role in the normal supply of coal in coal-fired power plants. [0003] Coal drop pipe is a common conveying equipment in the field of coal transportation in power plants, mainly used to realize the conversion and connection of coal between...
