Abstract

The utility model relates to a movable ventilating exhaust hood for workshops, which is characterized by comprising an exhaust hood (1) located above a noxious substance generating source, rollers (4) are mounted under the exhaust hood (1) and located on a guide track (5), an outlet of the exhaust hood (1) is fixedly connected with one end of an exhaust circular pipe (2), and the other end of the exhaust circuit pipe (2) is plugged in an exhaust square pipe (3). Aiming at a plurality of noxious substance producing devices which are not started simultaneously in workshops and can include a running device and a standby device, the movable ventilating exhaust hood can control a plurality of noxious substance generating positions, and each noxious substance generation position is not required to be provided with an independent exhaust hood. When a certain noxious substance producing device works, the movable ventilating exhaust hood moves to the noxious substance producing device to control noxious substances. Compared with a conventional scheme, the movable ventilating exhaust hood adopting the technical scheme is simple in system and low in air leak rate, steel consumption and investment.

Description

Movable type exhaust hood for workshop ventilation

Technical field

The utility model belongs to the industrial ventilation field, particularly relates to a kind of workshop ventilation movable type exhaust hood.

Background technology

The measure of workshop nuisance control in the industrial ventilation at present normally captures it at the pollutant scene portion's exhaust hood of setting a trap, and prevents that it from spilling into factory's internal contamination environment, influences workers ' health and process operation.In some workshops, production equipment is not opened simultaneously, as situations such as the using and the reserved, though the nuisance origination point is many, but do not work simultaneously, conventional way is all to establish an exhaust hood at each point, adds valve behind the exhaust hood, the exhaust hood valve that exhaust system is opened the production equipment correspondence of operation during work carries out nuisance control, idle valve closing.Obviously, this way causes system complex, and the valve inleakage is big, and the many investments of steel consumption are big.

Summary of the invention

The purpose of this utility model is exactly to produce the situation that equipment is not opened simultaneously at nuisance in some workshops, a kind of workshop ventilation movable type exhaust hood is provided, realize one-to-many control (exhaust hood is to a plurality of nuisance origination points), make that system is simple, investment is little.

The technical solution adopted in the utility model is as follows:

A kind of movable type exhaust hood for workshop ventilation, it is characterized in that it includes the exhaust hood that is positioned at top, nuisance generation source, roller is equipped with in the bottom of exhaust hood, and roller is driven and is located on the guide rail, the outlet of described exhaust hood is fixedlyed connected with air draft pipe one end, and the air draft pipe other end is inserted in the air draft square tube.

The both sides of described exhaust hood are provided with deep bead, and described roller is installed in the downside of deep bead.

Described roller is by motor-driven, and air draft square tube rear portion connects deduster.

The beneficial effects of the utility model have:

The utility model is owing to adopt above technical scheme, at a plurality of nuisance production equipments are arranged in some workshops, but the situation of not opening simultaneously, as situations such as the using and the reserved, can realize of the control of an exhaust hood, and need not to set up an exhaust hood at each point to a plurality of nuisance origination points.When a certain nuisance generation equipment was worked, exhaust hood promptly moved to nidus nuisance is controlled.Therefore, the technical program is simple than the conventional scheme system, air leak rate of air curtain is low, and steel consumption scalp is low.

Description of drawings

Fig. 1 is an elevation of the present utility model.

Fig. 2 is the cutaway view of the utility model along the A-A line among Fig. 1.

Wherein: 1-exhaust hood, 2-air draft pipe, 3-air draft square tube, 4-roller, 5-guide rail, 6-motor, 7-deep bead, the anti-source of students of 8-nuisance.

The specific embodiment

The utility model is further described below in conjunction with accompanying drawing:

As illustrated in fig. 1 and 2, the utility model is made up of exhaust hood 1, air draft pipe 2, air draft square tube 3, roller 4, guide rail 5, motor 6 and deep bead 7, the outlet of exhaust hood 1 and air draft pipe 2 are by being weldingly connected, relative fixed, air draft pipe 2 directly inserts in the air draft square tube 3, exhaust hood 1 is positioned at nuisance 8 tops, source takes place, roller 4 is equipped with in the bottom of exhaust hood 1, roller 4 is erected on the guide rail 5, roller 4 can roll under the driving of motor 6, and exhaust hood 1 can be moved to nuisance generation source relative to air draft square tube 3 on guide rail 5 with air draft pipe 2.The both sides of exhaust hood 1 are provided with deep bead 7, and described roller 4 is installed in the downside of deep bead 7, and the dusty gas that deep bead 7 can make nuisance generation source produce is sucked by exhaust hood 1 in the concentrated area more, improve the pollution discharge capability of exhaust hood 1.

When a certain nuisance generation equipment is worked in the workshop, the utility model movable type exhaust hood promptly can be moved to nidus nuisance is controlled.

During the utility model work, motor 6 drives roller 4 and rolls, and exhaust hood 1 moves to place, nuisance generation source and carries out exhausting, captures nuisance, and nuisance is delivered in the deduster at air draft square tube 3 rear portions, is discharged by blower fan.

Other undeclared part that the utility model relates to is same as the prior art.

Claims
