Abstract
The utility model relates to a material feeding funnel with a waste gas absorption cover, and can be used in chemical engineering and pharmaceutical industries. The material feeding funnel comprises a material feeding funnel body, a funnel connection flange, a gas suction pipe and an annular gas suction pipe, wherein the bottom of the annular gas suction pipe is sealed and fixed together with the external part of the material feeding funnel body; the inner edge of an annular air suction pipe on the annular gas suction pipe extends to the upper side of the material feeding funnel body. According to the material feeding funnel with the waste gas absorption cover, the bottom of the annular gas suction pipe is sealed and fixed together with the external part of the material feeding funnel body, and the inner edge of an annular air suction pipe on the annular gas suction pipe extends to the upper side of the material feeding funnel body; therefore, generated waste gas can be sucked away in a material feeding process. The material feeding funnel with the waste gas absorption cover can effectively collect the waste gas, hardly affects the material feeding work of the funnel, and is simple in structure and low in manufacturing.
Description
Technical field
The utility model relates to a kind of charging hopper with waste gas absorption cover, can be used in chemical industry, pharmaceuticals industry.
Background technology
In chemical industry, medicine and other fields, in the time using funnel reinforced, to prevent that chemical exhaust from letting out loose contaminated environment, not affecting again reinforced operation simultaneously.When reinforced, release because controlling chemical exhaust at present, be commonly used in funnel top and add air-suction cover, or add air-suction cover in funnel side, operation gas sampling is drawn and focused on.Although this method can effectively be collected waste gas, control and pollute, because there being air-suction cover to hinder, make very inconvenience of reinforced operation.
The utility model relates to a kind of charging hopper with waste gas absorption cover, the outside seal of the bottom of annular aspirate tube and charging hopper is fixed together, in annular aspiration channel on annular aspirate tube, edge extends to the top of charging hopper, in reinforced process, just the waste gas of generation can be siphoned away like this.The related a kind of charging hopper with waste gas absorption cover of the utility model, in effectively collecting waste gas, affects the reinforced operation of funnel hardly, and simple in structure, and cost of manufacture is lower.
Utility model content
In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical matters adopts: a kind of charging hopper with waste gas absorption cover, comprise charging hopper, funnel butt flange, aspirate tube and annular aspirate tube, the bottom of described annular aspirate tube and the outside seal of charging hopper are fixed together, in annular aspiration channel on annular aspirate tube, edge extends to the top of charging hopper, in described annular aspiration channel, edge forms admission port with the upper limb of charging hopper, one end of described aspirate tube connection relevant to annular aspirate tube, described, the connection relevant to flexible inhalation pipe of the other end of described aspirate tube, described aspirate tube is provided with suction modulation, the bottom of described charging hopper is provided with funnel butt flange, in annular aspiration channel, it is 3 centimetres along the distance of the upper limb to charging hopper.
The utility model relates to a kind of charging hopper with waste gas absorption cover, the outside seal of the bottom of annular aspirate tube and charging hopper is fixed together, in annular aspiration channel on annular aspirate tube, edge extends to the top of charging hopper, in reinforced process, just the waste gas of generation can be siphoned away like this.The related a kind of charging hopper with waste gas absorption cover of the utility model, in effectively collecting waste gas, affects the reinforced operation of funnel hardly, and simple in structure, and cost of manufacture is lower.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of a kind of charging hopper with waste gas absorption cover of the utility model;
Wherein: 1, charging hopper; 2, funnel butt flange; 3, annular aspirate tube; 4, suction modulation; 5, flexible inhalation pipe; 6, admission port; 7, edge in annular aspiration channel; 8, aspirate tube.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.Accompanying drawing is the schematic diagram of simplifying, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Refer to Fig. 1, a kind of charging hopper with waste gas absorption cover, comprise charging hopper 1, funnel butt flange 2, aspirate tube 8 and annular aspirate tube 3, the outside seal of the bottom of described annular aspirate tube 3 and charging hopper 1 is fixed together, in the annular aspiration channel of annular on aspirate tube 3 along 7 tops that extend to charging hopper 1, in described annular aspiration channel, form admission port 6 along 7 with the upper limb of charging hopper 1, one end of described aspirate tube 8 connection relevant to annular aspirate tube 3, described, the connection relevant to flexible inhalation pipe 5 of the other end of described aspirate tube 8, described aspirate tube 8 is provided with suction modulation 4, the bottom of described charging hopper 1 is provided with funnel butt flange 2, in annular aspiration channel, it is 3 centimetres along the distance of 7 upper limbs to charging hopper 1.
The utility model relates to a kind of charging hopper with waste gas absorption cover, the outside seal of the bottom of annular aspirate tube and charging hopper is fixed together, in annular aspiration channel on annular aspirate tube, edge extends to the top of charging hopper, suction modulation 4 can regulate air-breathing size according to different material, annular aspiration channel in along 7 and charging hopper 1 between form slit sectional area be less than annular passage sectional area, form the air-flow of higher wind at slit place, like this in reinforced process, just the waste gas of generation can be siphoned away, funnel butt flange 2 can be fixed on still by this charging hopper easily, on the charge door of the device such as tank.The related a kind of charging hopper with waste gas absorption cover of the utility model, in effectively collecting waste gas, affects the reinforced operation of funnel hardly, and simple in structure, and cost of manufacture is lower.
