Description

A Dredging System Combining Rotary Coal Hopper and Air Cannon

technical field

The invention relates to the field of mechanical equipment, in particular to a dredging system combined with a rotating coal hopper and an air cannon.

Background technique

Raw coal hopper arching has always been a common and extremely difficult problem in production. It has frequently occurred in coal storage and transportation, coal-fired power plants, metallurgy and other fields for a long time, which brings great difficulties to normal production and maintenance, and also makes production costs continue to increase. increase. The clogging of the hopper is caused by the compaction and arching of materials. The main reasons are: low temperature and poor fluidity of bulk materials; open storage of materials, rain and water spraying increase the humidity of materials and easily lead to compaction and arching; the inverted cone of the hopper The shape structure also increases the possibility of arching in the hopper; the arching in the hopper cannot be detected and dealt with in time, resulting in more compaction and difficulty in handling.

Rotary coal scuttle is an existing way to solve the problem of arching, but this method cannot completely solve the problem of raw coal arching. Arching is still prone to occur above the feed bin of the rotating coal hopper and at the bottom of the rotating coal hopper .

In order to achieve the above object, the present invention proposes a dredging system combining a rotary coal scuttle and an air cannon; it includes a rotary coal scuttle, an air cannon and an air hammer; The above-mentioned air hammer is installed under the outer wall of the rotating coal hopper.

The air cannon is installed in the middle of the feed bin above the rotating coal hopper; the feed bin includes an upper feed section and a lower feed section; the air cannon is installed between the upper feed section and the lower feed section place.

The section of the upper feeding section is rectangular, and the section of the lower feeding section is an inverted trapezoid; the air cannon is installed horizontally at the joint between the upper feeding section and the lower feeding section.

The air cannon includes at least four air cannons arranged at even intervals; the air cannons are installed outside the silo wall of the feed bin through brackets, and two of the air cannons are arranged symmetrically.

The bracket includes a horizontal bracket and an oblique bracket; the oblique bracket is installed outside the bin wall of the lower feeding section with oblique fit, and the horizontal bracket is fixedly connected outside the bin wall of the lower feeding section; the air cannon is installed on the horizontal on the stand.

The air cannon is installed at the joint between the upper feeding section and the lower feeding section, and the air cannon blowing pipe is welded on the silo wall.

The blowing pipe of the air cannon is horizontally facing into the feeding bin, so that the ejected compressed air is horizontally facing into the feeding bin.

The blowing pipe of the air cannon is arranged obliquely downward, so that the compressed air ejected is obliquely downward and faces into the feeding bin.

The air hammer is installed on the side bottom of the outer wall of the rotary coal hopper through a bracket, and the air hammer is installed on the outer wall of the lower fixed bin of the rotary coal hopper.

Two air hammers are arranged symmetrically on the outer wall of the lower fixed bin of the rotary coal hopper.

Beneficial effect:

Through the set rotating coal scuttle, air cannon and air hammer; above the rotating coal scuttle, the air cannon is used to dredge the possible arching position in the silo, and the possible arching is dredged through the rotating coal scuttle. Then under the rotating coal hopper, the vibration of the air hammer is used to further dredge the possible arching position to ensure that the silo is evenly discharged.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The present invention proposes a dredging system combined with a rotary coal hopper and an air cannon; it includes a rotary coal hopper 1, an air cannon 3 and an air hammer 4; the air cannon 3 is installed on the outer wall of the upper feeding bin 2 of the rotary coal hopper 1; The air hammer 4 is fitted under the outer wall of the rotary coal hopper 1 .

The air cannon 3 is installed in the middle of the feed bin 2 above the rotary coal hopper 1; the feed bin 2 includes an upper feed section 21 and a lower feed section 22; the air cannon system 3 is installed in the upper feed section 21 and the connection between the lower feed section 22.

The section of the upper feeding section 21 is rectangular, and the section of the lower feeding section 22 is an inverted trapezoid; the air cannon 3 is installed horizontally at the joint between the upper feeding section 21 and the lower feeding section 22 .

The air cannon 3 includes at least four air cannons arranged at even intervals; the air cannon 3 is installed outside the bin wall of the feed bin 2 through a bracket, and two of the air cannons 3 are arranged symmetrically.

The support includes a horizontal support 6 and an oblique support 5; the oblique support 5 is obliquely fitted outside the warehouse wall of the lower feeding section 22, and the horizontal bracket 6 is horizontally fixedly connected outside the warehouse wall of the lower feeding section 22; The air cannon 3 is mounted on the horizontal support 6 in cooperation.

The air cannon 3 is installed at the junction between the upper feed section 21 and the lower feed section 22, and the blowing pipe of the air cannon 3 is welded on the silo wall.
