Abstract
The utility model provides a modular annular take out dust hood mouth includes semi -ring shape rear cover 1, rear cover handle 2, semi -ring shape front shroud 3, and the front shroud handle 4, pipeline connection port 5. The cyclic annular diameter of semi -ring shape rear cover 1 and semi -ring shape front shroud 3 match that the butt joint can form complete annular, semi -ring shape rear cover 1 form complete annular vertical section shape with 3 butt joints of semi -ring shape front shroud and be (img file='DSA0000123060560000011. TIF'wi='103'he='46' /). The utility model discloses can change along with the operating condition of the medium frequency induction furnace fire door be applied to and change, perfect laminating medium frequency induction furnace or electroslag furnace fire door, the utility model discloses connect have an air pipe of lasting negative pressure after, carry out entrapment to the flue gas dust that produces in medium frequency induction furnace or the electroslag furnace, the entrapment effect is obvious, can make the flue gas dust not escape the diffusion to open the space in to the assurance has the dirt smoke pollution of not being pollinated of intermediate frequency electric stove or electroslag furnace work -house, and personnel's is healthy in the protection place space.
Description
Technical field
What this utility model related to industrial dedusting removing exhaust gas field takes out dust hood mouth, particularly relates to a kind of knockdown annular and takes out dust hood mouth.
Background technology
Existing industrial dedusting removing exhaust gas field take out dust hood mouth, various informative, on various dust treatment systems, have applications well. but process at the exhaust gas dust for fire door, particularly at the annular fire door for the medium-frequency induction furnace of melting and electroslag furnace, it is existing that to take out dust hood degree of lip-rounding formula single, can not fit the annular fire door of medium-frequency induction furnace or electroslag furnace, well the exhaust gas dust produced in medium-frequency induction furnace or electroslag furnace work process effectively can not be trapped, cause the place having medium-frequency induction furnace or electroslag furnace work, exhaust gas dust easily diffuses in the open space of medium-frequency induction furnace or electroslag furnace working space, formation exhaust gas dust pollutes, the occupational health of personnel in serious harm site space.
Summary of the invention
Taking out the indeterminable problem of dust hood mouth to solve above-mentioned tradition, this utility model provides a kind of knockdown annular to take out dust hood mouth.
For realizing object above, the technical solution adopted in the utility model is: a kind of knockdown annular takes out dust hood mouth, and it includes semi-circular back cover 1, back cover handle 2, semi-circular front shroud 3, front shroud handle 4, conduit connection end mouth 5; It is characterized in that described semi-circular back cover 1 is similar y-type structure; Described back cover handle 2 is installed on the end face center of semi-circular back cover 1; Described semi-circular front shroud 3 is similar U-shape structure; Described front shroud handle 4 is installed on the middle position up and down, side of semi-circular front shroud 3; Described conduit connection end mouth 5 one end is connected with described semi-circular back cover 1, and the other end can connect ventilation shaft; Described semi-circular back cover 1 is suitable with the ring-type diameter of semi-circular front shroud 3, and docking can form complete annular; Described semi-circular back cover 1 docks the vertical cross section forming complete annular and is shaped as with semi-circular front shroud 3
The beneficial effects of the utility model are: this utility model energy perfect laminating medium-frequency induction furnace or electroslag furnace fire door, after this utility model connects the ventilation shaft with continuous negative pressure, the exhaust gas dust produced in medium-frequency induction furnace or electroslag furnace is trapped, trapping effect is obvious, exhaust gas dust can be made not escape and to diffuse in open space, thus ensureing that the place having middle frequency furnace or electroslag furnace work is not polluted by dust flue gas, the injury of the dust flue gas that the health of personnel is not produced by medium-frequency induction furnace or electroslag furnace in protection site space;Simple in construction of the present utility model, easy to operate, work at medium-frequency induction furnace or electroslag furnace and be in steady statue, when not needing manually medium-frequency induction furnace or electroslag furnace to be operated, this utility model can completely be fitted in fire door, work at medium-frequency induction furnace or electroslag furnace and be active, have artificial to when being operated in electric furnace and stove, structure of the present utility model can change, specific features is described semi-circular back cover 1 and semi-circular front shroud 3 all can be moved to the position not interfering with operative by handle, when the work of medium-frequency induction furnace or electroslag furnace is in steady statue, semi-circular back cover 1 and semi-circular front shroud 3 to fire door is moved again through handle, form ring-type and be fitted in fire door position.
