Steady flow control air pressure balancer

Abstract

A steady-flow control air pressure balancer relates to the technical field of wind power transmission. It includes an air inlet pipe, an air outlet pipe and a valve body. The valve body is provided with a valve cavity, and both ends of the valve cavity are respectively connected with an air inlet pipe and an air outlet pipe. The rear section of the valve cavity is the first conical diversion section, the front section of the valve cavity is the second conical diversion section, the cylindrical middle section between the first conical diversion section and the second conical diversion section, the valve cavity There is a fluid guide assembly and a fluid guide bracket in the middle; the fluid guide assembly includes a guide body and a cylindrical casing, and an electric cylinder for driving the guide body to move forward and backward is fixedly installed in the cylindrical casing. The width of the gap between the cavity walls of the second conical diversion section can adjust the working wind pressure of the corresponding winding unit; the diversion support includes a strut, the cylindrical shell and the valve body are fixedly connected to the strut, and the strut An air intake channel communicated with the external environment and an exhaust hole communicated with the inner cavity of the cylindrical shell are opened inside.

Description

technical field [0001] The invention relates to the technical field of wind conveying, in particular to a steady flow control wind pressure balancer. Background technique [0002] In the cigarette factory, the lifting process of the cut tobacco to the ribbon is mainly completed by the process wind. The process wind branch pipes of each unit are connected to the process wind main pipe in parallel, and the parameters related to the process wind power are designed according to the number of incorporated coiling units. Since the technological wind parameters of each coiling unit are different from each other, the branch cigarette pressure of each unit is determined according to the working conditions of the unit. When the organic unit has troubles such as running bars and paper breaks, the rolling unit is in a standby state; when the production scheduling arrangement requires some units to change cigarette brands or stop production, the rolling unit is in a shutdown state. The...

Problems solved by technology

Although the electric wind pressure balancer can automatically control and adjust the wind pressure according to the working conditions of the coiler, when a coiler is in the standby state, it can automatically control the adjustment of the wind pressure to keep the process wind parameters of other normal production coilers. It remains unchanged, but it still has the following defects: the driving device (including transmission parts) that drives the movement of the guide body is mainly located outside the valve body and has a large volume and complex structure, which leads to the bulky size of the entire air pressure balancer and inconvenient installation.
