Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system in which the paddles of a plurality of paddle screw conveyors are used to transport dust, soot, ash, and other similar powders that tend to adhere to the paddles, collected by a dust collection device. This invention relates to a dust collecting and discharging mechanism that has good discharging efficiency by cleaning dust that adheres to both the front and back surfaces.

A rotation ratio of 2:1 is set in which the paddles of one of the paddles in the plurality of parallel shafts intersect with the paddles of the adjacent shaft, and the number of paddles is inversely proportional to the rotation ratio of each shaft. The structure is such that a minimum gap is maintained to avoid contact when the paddles cross each other.

When powder adheres to the paddles of paddle conveyors that have been commonly used in the past, the conveyance efficiency of the powder is significantly reduced and the conveyor is extremely inefficient.

This drawback was especially severe when dealing with humidified ash, soot, etc.

The present invention aims to solve these problems and provide a dust collecting and discharging device that doubles the kneading and removal functions.

An example of implementing the invention will be described with reference to the drawings.

First Embodiment As shown in FIGS. 1 and 2, the rotation ratio of the shafts 2 and 3 arranged in parallel in the trough 1 is set to 2=1.

On the shaft 2, paddles 4, 4 are symmetrically arranged opposite to the axis at an angle of 60° or less, and on the shaft 3, similarly to the shaft 2, paddles 5, 5.5 are arranged opposite to the axis at the same angle of 60° or less, Both are arranged on the axis,
In addition, these paddles 4A and 5 are constructed so that when the two paddles cross each other due to the rotation of the shaft, there is an extremely small gap.

Thus, the number of paddles on the paddle shaft whose rotation ratio is set to 2=1 is inversely proportional to the rotation ratio.

As shown in FIG. 3A, by arranging the shafts from the above embodiment,
The shafts are arranged by placing the shaft 2 in the first embodiment in the center and the shafts 3, 3 in parallel on both sides thereof, or by positioning the shaft 2 at the apex of the shafts 3, 3 and above the shafts 3, 3, as shown in B. The paddles are configured so that they do not come into contact with each other.

The rest is the same as the first embodiment.

Because of the above configuration, the shaft 2 is operated at twice the rotational speed of the other shaft 3, and the paddles of both shafts face each other with a very small gap, and the paddles of both shafts are used to transfer powder whose viscosity has increased due to humidification, etc. Even if highly viscous powder or the like adheres to the paddle, the rotation ratio of the shaft allows the powder to be mutually scraped off and cleaned from both the front and back surfaces of the paddle.

By cleaning the powder adhering to the paddle, the paddle performs its discharging function, and the discharging is doubled compared to a normal paddle conveyor with a rotation ratio of 1=1, and the functions of humidification, kneading, and discharging are calculated to be more efficient. can always be held.

For example, if the processing capacity of a conventional paddle screw conveyor installed on a shaft with a rotation ratio of 1 = 1 is It/h, it is easily 2
Since it can process tons, the capacity can be made smaller.

With the above configuration and operation, the rotation ratio of one of the parallel shafts is set to double, and the number of intersecting paddles is arranged unevenly in inverse proportion to the rotation ratio of the shafts, thereby reducing dust adhering to both the front and back surfaces of each other. Since it has become possible to clean it, it has made it possible to increase discharge efficiency and reduce equipment costs.
