Abstract
The utility model discloses a liftable exhaust hood, which comprises an exhaust hood. The exhaust hood is fixed to the tail end of an exhaust hood support, an electric hoist is connected to the top end of the exhaust hood support, and exhaust hood support pulleys are disposed on two sides of the exhaust hood. When the electric hoist works, the exhaust hood support is pulled, and the exhaust hood support pulleys move along a guide rail. A motor support is mounted at the top end of the guide rail, the electric hoist is disposed on the motor support, and the edge at the bottom of the exhaust hood is flanged inwardly to form an oil collecting groove. The liftable exhaust hood solves the problem that an existing exhaust hood which is fixedly mounted cannot move, simultaneously solves the problem that the existing exhaust hood can not collect small solid-liquid particles in waste gas to cause pollution, is convenient in use as the exhaust hood can move up and down, can recycle liquid drops and the small solid particles in the waste gas, and prevents pollution to products.
Description
Technical field
The utility model relates to the draft hood field, particularly a kind of Liftable type draft hood.
Background technology
At present, enterprises such as medicine, chemical industry are mostly fixed with draft hood, and in pumping process, the liquid granule in the waste gas comes off at random through regular meeting, drops on the product polluted product.This class is bled and is covered with two open defects: the one, because draft hood fixed installation, exhaust fan can not move up and down, thus use and when overhauling, all inconvenient; The 2nd, if waste gas contains more drop and solid granule, drop and solid granule drop at random, polluted product.
Publication number is that the utility model file of 201555285U discloses a kind of exhaust fan with automatic lifting function, but it mainly is used on the household smoke exhaust ventilator, and described elevating function is that the flexible of tube tube finished.Its lowering or hoisting gear only is applicable on the small household appliances product, is not suitable for large-scale draft hood.
In sum, there is following shortcoming in present draft hood: one, draft hood fixed installation, can not move up and down when bleeding, and be unfavorable for using and overhauling; Two, drop in the waste gas or solid granule are not reclaimed, when it comes off, polluted product.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of Liftable type draft hood is provided, and draft hood can move up and down, and convenience is used, and can reclaim drop and solid granule in the waste gas, prevents polluted product.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of Liftable type draft hood, comprise draft hood, and described draft hood is fixed on draft hood support tail end, and the draft hood cantilever tip connects electric block, and its both sides are provided with draft hood support pulley; During electric block work, pulling draft hood support, draft hood support pulley is along guide rail movement; Electric machine support is installed on described guide rail top, and electric block is arranged on the electric machine support; Described draft hood bottom margin forms oil trap to in-flanges.
For ease of the working condition in the draft hood of monitoring observation at any time, described draft hood has form, the draft hood sight glass of transparent tempering is installed in the form, and form is an arbitrary shape.
For in time cutting off burning things which may cause a fire disaster, plastic skeleton fire retardant bushing type exhaust duct is installed on the described draft hood.
Be the accurately motion of control draft hood support, limit switch is installed in described guide rail both sides.
The utility model has following beneficial effect with respect to prior art:
1, structure of the present utility model both can make draft hood move up and down, the convenient use; Can reclaim the liquid granule in the waste gas again, prevent polluted product;
2, the form of draft hood of the present utility model, the working condition in the draft hood is observed in monitoring at any time;
3, on the draft hood of the present utility model exhaust duct is installed, if it is breaking out of fire can in time cut off burning things which may cause a fire disaster, safe and reliable;
4, the utility model is provided with limit switch, accurately controls the motion of draft hood support.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is a upward view of the present invention.
The specific embodiment
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, be structural representation of the present utility model, a kind of Liftable type draft hood, comprise draft hood 1, described draft hood 1 is fixed on draft hood support 3 tail ends, and draft hood support 3 tops connect electric block 5, and its both sides are provided with draft hood support pulley 8; During electric block 5 work, pulling draft hood support 3, draft hood support 3 pulleys move along guide rail 4; Electric machine support 6 is installed on described guide rail 4 tops, and electric block 5 is arranged on the electric machine support 6; After starting electric block 5, draft hood 1 just can move up and down along guide rail 4, conveniently uses and overhauls.
Described draft hood 1 bottom margin forms oil trap 10 to in-flanges, and this oil trap 10 is used to reclaim drop and solid granule, but and draft hood 1 bottom regular dismounting cleaning.
Described draft hood 1 has form 2, and the shape of form 2 is any, and the draft hood sight glass of transparent tempering is installed in the form 2, and the Manufacturing Worker can check production status by draft hood form 2, finds to produce unusually and in time and handles.
Connect plastic skeleton fire retardant bushing type exhaust duct 7 on the described draft hood 1; Both can when breaking out of fire, in time cut off burning things which may cause a fire disaster, and also can waste gas be delivered to off-gas cleaning equipment and handle, after the processing, be discharged into the external world by blower fan again by plastic skeleton fire retardant bushing type exhaust duct 7.
Be the accurately motion of control draft hood support 3, limit switch 9 is installed in described guide rail 4 both sides, also can prevent 8 out-of-bounds of draft hood support pulley.
As mentioned above, just can realize the utility model preferably, the foregoing description is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be that all equalizations of being done according to the utility model content change and modification, all contained by the utility model claim scope required for protection.
