Abstract
The utility model discloses a blower, which comprises an air inlet, a casing, an impeller, a rotary shaft and a motor. The blower further comprises a bearing box and a coupling. The bearing box is added to the rotary shaft. The rotary shaft is lengthened. The bearing box is connected with the motor through the coupling. A stuffing box if added to the casing at the rotary shaft to prevent air leakage. The blower can be used for delivering toxic gases, and is low in pressure, low in power, low in energy consumption, low in operational cost, simple in structure and convenient in use.
Description
Technical field
The utility model relates to a kind of blower, belongs to the gas delivery field.
Background technique
The small-sized centrifugal blower of 9-19 is made up of impeller, casing, intake grill and support, and impeller is characterized in that directly by driven by motor pressure is high, is that other centrifugal blower institute is inaccessiable; Simple in structure, cheap, this also is that other high pressure blower is incomparable.Direct-connected because of its impeller and motor, rotating shaft is short, no SLD, and rotating shaft place gas leakage is very big, can only be used for the conveying of air, for carrying air, leaks any and can not exert an influence to environment.
In using cleaning by dry process toxic gas process, will carry toxic gas with blower, cleaning by dry process is bigger because of the catalyzer resistance that uses, and general centrifugal blower can not reach the requirement of pressure.In the toxic gas course of conveying, do not allow leakage again, otherwise, environment is produced pollution.If then equipment is huge with Roots blower, and power is very big, and energy consumption is high, is difficult to adopt.Domestic for the also not production of the minitype high voltage centrifugal blower of carrying toxic gas, this has brought midget plant to produce a difficult problem to cleaning by dry process.
Summary of the invention
The utility model has overcome the deficiency of existing technology, and a kind of blower is provided.
The blower of the utility model is on 9-19 type small blast fan basis, to carry out improvedly, utilizes its pressure high, the characteristics that power is little; On the basis of intake grill, casing, impeller, rotating shaft and the motor of 9-19 blower; Add stuffing box in body fuselage rotating shaft place, gas leakage can be regulated, prevented to stuffing box, and in rotating shaft, set up the plain bearing case; Length lengthening rotating shaft according to stuffing box and bearing housing; Bearing housing is connected with motor through coupling, and intake grill, casing, bearing housing and motor are fused with support, forms a novel high pressure centrifugal blower that does not leak; Be used to carry toxic gas to make 9-19 high pressure centrifugal blower purposes more extensive after the transformation, also created advantage for small-sized cleaning by dry process device.
The utility model can be used for the conveying of toxic gas.
The utility model with respect to the advantage of existing technology is:
(1) purposes is more extensive, can be used for carrying toxic gas, prevents the pollution of the environment.
(2) pressure is high, can be used for the bigger occasion of resistance.
(3) power is little, and energy consumption is low, and operating cost is low.
(4) framework is simple, and is cheap, easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is intake grill among the figure, the 2nd, and impeller, the 3rd, casing, the 4th, stuffing box, the 5th, rotating shaft, the 6th, bearing housing, the 7th, coupling, the 8th, motor, the 9th, support.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain, but the utility model protection domain is not limited to said content.
The blower of the utility model comprises intake grill 1, casing 3, impeller 2, rotating shaft 5 and motor 8; Also comprise bearing housing 6 and coupling 7; Bearing housing 6 is set up in rotating shaft 5, and rotating shaft 5 length increase, and bearing housing 6 is connected with motor 8 through shaft coupling 7 devices; Stuffing box 4 is added in body fuselage 3 rotating shafts place, and intake grill 1, casing 3, bearing housing 6 and motor 8 usefulness supports 9 fuse.
The utility model blower is used for purifying the adsorbent equipment of storage phosphine gas, adopts the blower of the present invention gas of will store in a warehouse to extract out and be forced into more than the 20kpa, be sent in the quartzy electric heat exchanger that generates heat of chuck; The energising heat supply; Between 80～100 ℃, the outer pipe from heat exchanger after the gas heat exchange of loosing is discharged through the automatic temperature control instrument A.T.C, feeds and is equipped with in the adsorber of dephosphorization catalyzer; Through the dephosphorization catalyzer in the adsorber; Hydrogen phosphide in the diffusing gas of absorption storage, the diffusing gas after the purification enters atmosphere, purifies back gas and is lower than NBS 0.2ppm through detecting phosphine concentration.
Claims (2)
1. a blower comprises intake grill, casing, impeller, rotating shaft and motor, it is characterized in that: blower also comprises bearing housing and coupling; Bearing housing is set up in rotating shaft; Shaft length increases, and bearing housing is connected with motor through coupling, and stuffing box is added in body fuselage rotating shaft place.
2. blower according to claim 1 is characterized in that: intake grill, casing, bearing housing and motor are integral through groups of holders.
