Abstract
The invention provides a suspension suction hood, which comprises a suction hood, a suction plate, adjusting plates, a diversion cone and a support frame, wherein the suction plate is arranged on the upper layer of the support frame, and is a square sheet on which strip-shaped through holes are distributed; two adjusting plates which are parallel to each other and can move leftwards and rightwards respectively are arranged on the suction plate; two semicircular holes are cut in the middles of a left adjusting plate and a right adjusting plate; the diversion cone is assembled, and is a conical body with a pointed end; the left adjusting plate and the right adjusting plate are oblong-shaped sheets on which the strip-shaped through holes are distributed; and the suction hood is arranged above the suction plate. The invention has the advantages that: the suction negative pressure loss in the suction hood is extremely small, dust in suction holes is convenient to clear, and dust floating in the air can be absorbed effectively.
Description
Technical field
The present invention is applicable to that producing the inside, lead-acid accumulator workshop absorbs the perhaps indoor place of other toxic dust, nontoxic dust of aerial poisonous lead powder dirt of floating.
Background technology
At present, electric bicycle generally uses in the whole nation, but most of electric bicycle still uses lead-acid accumulator as active force, is producing lead powder dirt, the lead fume mist that the inside, polar plate of lead acid storage battery workshop is being floated a large amount of.If lead powder dirt, the lead fume mist through in the respiratory system suction body, can be caused the health lead poisoning by the site operation personnel.At present also there is not effectively to drive away the equipment of lead powder dirt in the air.
Summary of the invention
Produce the showy aerial poisonous lead powder dirt in the inside, lead-acid accumulator workshop in order to reduce; Causing that operating personnel's lead poisoning and lead powder dirt flow with air floats towards the reality of outdoor pollution plant area surrounding environment along window, the present invention provides a kind of suspension type dust shield that has deflection cone and adjustable plate to absorb the lead powder dirt that floats in workshop air.
The technical solution adopted for the present invention to solve the technical problems is: it comprises dust shield, dust-catching board, adjustable plate, deflection cone and support frame several sections.Air-suction duct is arranged on the dust shield, and air-suction duct is with on the outer dedusting induced-draught fan of major diameter plastic tube junction chamber, and the inlet velocity of air-suction duct is not less than 10 meters of per seconds.The support frame upper strata is a dust-catching board; Dust-catching board is a square thin plate-be covered with an onboard strip through hole; Be close to two parallel adjustable plates that can move to the left and right separately above the dust-catching board, in the middle of left adjustable plate and right adjustable plate, cut out two semicircle orifices, deflection cone of assembling in semicircle orifice; Deflection cone is the conically shaped body of a band tip, and deflection cone faces the centre of the air-suction duct on the dust shield.Deflection cone orders about dust shield intracavity bottom air draught air-flow and is drawn close to the centre by the edge, surrounding.Left side adjustable plate, right adjustable plate is two block length square plates, is covered with the strip through hole onboard; During work: regulate and be close to the adjustable plate on the dust-catching board, making air suction opening is the slit state, has reduced the loss of air draught negative pressure in the dust shield like this.If air suction opening stops up, adjusting-adjustable plate enlarges air suction opening, is convenient to the dust in the cleaning eye.It above dust-catching board a dust shield.Suspension type dust shield of the present invention need be connected on the outdoor dedusting induced-draught fan.
The invention has the advantages that: can effectively absorb the aerial dust that floats.
