Problems solved by technology

[0004] At present, some clinker factories use a rotary feeder to prevent air leakage at the raw material entrance of the raw material vertical mill. Because the raw materials contain limestone of different sizes, the shell of the feeder is constantly collided and worn. There are gaps and air leakage in the feeder, which leads to a decrease in the output of raw materials, and at the same time causes a certain degree of difficulty in on-site maintenance

Embodiment Construction

[0018] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a buffer air lock bin 1, and the buffer air lock bin 1 includes a bin body 2, a rotary feeder 3 is installed under the bin body 2, and a load cell 4 is installed at the bottom of the bin body 2. The weighing sensor 4 and the rotary feeder 3 are respectively connected with the control box.

[0019] Adopting a raw material vertical mill air lock feeding device of the present invention, when the raw material enters the bin body 2, a natural accumulation seal is formed to prevent air leakage, the rotary feeder 3 rotates to throw the material out, and the weighing sensor 4 measures the buffer lock in real time The weight of the air bin 1 sends the signal to the control box, and the controller automatically adjusts the rotating speed of the rotary feeder 3 according to the weight change of the buffer lock air bin 1, and always maintains a certain material layer thickness t...

Abstract

The invention relates to an unloading device, in particular to a raw material vertical mill lock air unloading device. The raw material vertical mill lock air unloading device is characterized by comprising a buffer lock air bin; the buffer lock air bin includes a bin body; a rotating feeder is mounted below the bin body; and a weighing sensor is mounted at the bottom of the bin body. The raw material vertical mill lock air unloading device has the beneficial effects of: thorough solution of the problems as high wear, air leakage and difficult maintenance in a traditional rotating unloader, simple and reliable design, convenience to maintain, capability of preventing air from leaking after use, increment of the raw material yield, and reduction of the maintenance cost.

Description

[0001] (1) Technical field [0002] The invention relates to a cutting device, in particular to an air-locked cutting device for a raw material vertical mill. [0003] (2) Background technology [0004] At present, some clinker factories use a rotary feeder to prevent air leakage at the raw material entrance of the raw material vertical mill. Because the raw materials contain limestone of different sizes, the shell of the feeder is constantly collided and worn. There are gaps and air leakage in the feeder, which leads to a decrease in the output of raw materials, and at the same time causes a certain degree of difficulty in on-site maintenance. [0005] (3) Contents of the invention [0006] In order to make up for the deficiencies of the prior art, the present invention provides a raw material vertical mill air-locked feeding device that is simple and reliable in design, easy to maintain, prevents air leakage, and improves raw material output. [0007] The present invention ...
