Abstract
The utility model provides an improved supercharging blower for coal gas transmission, which comprises a shell and a front cover plate, wherein the shell is fixedly connected with the front cover plate. The improved supercharging blower is characterized in that two layers of flanges are added on an inner circle of a front lateral plate of the shell, and sealing materials are disposed between the two layers of flanges on the inner circle of the front lateral plate and the front cover plate for sealing. The seal between the shell and the front cover plate has simple structure, convenient replacement and good sealing effect, which basically avoids exosmosis and leakage of gas tar. Besides, fixed bolts on the shell are more convenient in replacement, thereby simplifying operation.
Description
Technical field
The utility model relates to a kind of blower of conveying gas, particularly is applicable to the rigorous gases of tightness such as carrying coal gas.
Background technique
Blower because the casing internal pressure is excessive, causes between casing and the front shroud tar that exosmoses to occur, and slight gas leak phenomenon is arranged when carrying coal gas.Time has been grown heavy corrosion, influences the blower fan using effect, and has potential safety hazard.The blower casing of present conveying gas and the sealing of front shroud mainly are round turn packings between casing front side plate and front shroud.Though do so simply, operation causes above-mentioned potential safety hazard easily easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of booster fan of improved conveying coal gas, stops the seepage phenomenon of tar, stops gas leak phenomenon, removes a hidden danger.
The booster fan of a kind of improved conveying coal gas of the utility model, comprise casing, front shroud, casing is fixedlyed connected with front shroud, it is characterized in that the interior circle of front side plate of described casing is gone up two layers of flange of increase, is added with the sealing material sealing in the front side plate between round two layers of flange and the front shroud.
The utility model is on original preparation process basis, has designed and produced two layers of flange at casing front side plate inner circle, and former packing_seal is changed into the sealing material (mainly being good seal performance) of special import material.Reach thus between casing and the front shroud and the tar that exosmoses, gas leak phenomenon can not occur.The time of stopping has been grown heavy corrosion, influences the blower fan using effect, and has potential safety hazard.
Advantage of the present utility model: casing and the sealing configuration between the front shroud that the utility model provides are simple, and it is convenient to change, and has good sealing effect, stops exosmosing and gas leak phenomenon of gas tar substantially.Replacing to the fixing bolt on the casing is convenient, easily operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion enlarged view among Fig. 1.
Among the figure: 4 two layers of flange of 1 blower fan export standard flange 2 front shrouds, 3 sealing materials, 5 front side plates, 6 casings
Embodiment
As shown in the figure, the booster fan of a kind of improved conveying coal gas of the utility model, comprise casing 6, front shroud 2, casing 6 is bolted to connection with front shroud 2, the major technique characteristics are, circle is gone up in the front side plate 5 of casing increases by two layers of flange 4, is added with sealing material 3 sealings in the front side plate between two layers of flange 4 of circle and the front shroud 2.
Claims (1)
1, a kind of booster fan of improved conveying coal gas, comprise casing (6), front shroud (2), casing is fixedlyed connected with front shroud, the interior circle of front side plate (5) that it is characterized in that described casing (6) is gone up increase by two layers of flange (4), is added with sealing material (3) sealing in the front side plate between round two layers of flange (4) and the front shroud (2).
