Abstract
The utility model provides an energy-saving environment-protective blower, which comprises a casing and a bearing box. The casing is provided with an air inlet and an air outlet, a spindle supported on a bearing in the bearing box is driven by a power source, and an impeller is mounted at one end, extending into the casing, of the spindle. The blower is characterized in that a sealing component is mounted between the spindle and the casing, the sealing component includes a sealing sleeve, a sealing outer sleeve and a seal piece, the sealing sleeve provided with a sealing disc is mounted on the spindle, the sealing outer sleeve arranged at the front end of the sealing sleeve matches with the sealing sleeve and is fixed onto the casing, the seal piece arranged at the rear end of the sealing sleeve matches with the sealing sleeve and is fixed onto the casing, and high-temperature-resistant seals are respectively mounted between the sealing outer sleeve with the sealing sleeve, between the seal piece and the sealing sleeve and between the end surface of the sealing disc and the end surface of the seal piece. The energy-saving environment-protective centrifugal blower not only can convey high temperature gas, but also can convey coal gas, saves energy and protects environment.
Description
Technical field:
The utility model is relevant with blower, especially with not only can carry high-temperature gas but also can carry the energy-conserving and environment-protective centrifugal blower of coal gas relevant.
Background technique:
Commercially available D type centrifugal blower is made up of the casing that contains intake grill, exhaust outlet, bearing housing, main shaft, impeller etc. at present, adopts conventional seals between main shaft and casing, so can only carry normal temperature or maximum temperature can not surpass 80 ℃ gas; And can not carry high-temperature gas.And the commercially available blower fan that can carry high-temperature gas can not be carried coal gas at present.A large amount of high temperature that present calcium carbide production industry produces in producing the calcium carbide process, the tail gas of high-load coal gas can't be recycled.The casing of commercially available D type centrifugal blower is an integral body, so inlets and putlets of ventilation is non-adjustable.
The model utility content:
The purpose of this utility model is in order to overcome above deficiency, a kind of energy-conserving and environment-protective centrifugal blower that not only can carry high-temperature gas but also can carry coal gas to be provided.Another purpose of the present utility model is in order to provide a kind of exhaust outlet adjustable, energy-conserving and environment-protective centrifugal blower easy to use.
The purpose of this utility model is achieved like this:
The utility model energy-conserving and environment-protective centrifugal blower, include the casing of intake grill and exhaust outlet, bearing housing, being supported on the main shaft that driven by power source on the bearing in the bearing housing stretches on the end of casing impeller is housed, it is characterized in that between main shaft and casing black box being housed, the stuffing box gland that the band seal disc that is contained on the main shaft is arranged in the black box, place the stuffing box gland front end cooperate with stuffing box gland and be fixed on hermetically sealed case on the casing, place that the stuffing box gland rear end cooperates with stuffing box gland and be fixed on seal on the casing, between hermetically sealed case and the stuffing box gland, between seal and the stuffing box gland, between seal disc end face and the seal end face refractory seal are housed respectively.
On the end face of above-mentioned seal disc and the seal end face tooth of working in coordination is arranged, the tooth of working in coordination is arranged on hermetically sealed case and the stuffing box gland.
The inflated with nitrogen interface is arranged on the above-mentioned seal.
Above-mentioned casing is made up of the front housing of bringing the air port into, back cabinet, the spiral case of taking the air port out of that is positioned between forward and backward casing, and the periphery of front housing, spiral case, back cabinet connects by link.
The utility model is linked to each other with the outlet of equipment tail gas, recovery plant import respectively into and out of the air port, during work, thereby main shaft rotates the impeller rotation under power source drives, thereby the medium that enters casing from intake grill enters recovery plant from exhaust outlet pressurization outflow under the drive of impeller.
Compare with existing D type centrifugal blower; The utlity model has as advantage:
1, adopt the medium of carrying behind the black box can not leak, and the sealing medium gas flow that consumes seldom, not only can carry high-temperature gas but also can carry coal gas, pressurized delivered by the utility model blower fan can be with former emptying waste of fuel heat energy and available inflammable gas send back to combustion furnace and produce calcium carbide, solve the problem that the tail gas of a large amount of high temperature that the calcium carbide production industry produces, high-load coal gas can't be recycled in producing the calcium carbide process, and reduced CO energy-conservation the time again
2Discharging, energy-saving and environmental protection;
2, casing adopts combined type, and exhaust outlet is adjustable, and is easy to use, satisfies market demand.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the A portion enlarged view of Fig. 1.
Fig. 3 is another structural representation of the utility model.
Fig. 4 is the utility model structural representation again.
Embodiment:
Referring to Fig. 1, Fig. 2, this example energy-conserving and environment-protective centrifugal blower comprises casing 1, bearing housing 2, is supported on the main shaft that is subjected to driven by motor 4 on the bearing 3 in the bearing housing and stretches on the end of casing impeller 5 is housed.Casing is made up of the front housing 6 of bringing the air port into, back cabinet 7, the spiral case of taking the air port out of 8 that is positioned between forward and backward casing, and the periphery of front housing, spiral case, back cabinet connects by bolt assembly 9.Black box 10 is housed between main shaft and back cabinet.The stuffing box gland 12 that the band seal disc 11 that is contained on the main shaft is arranged in the black box, place the stuffing box gland front end cooperate with stuffing box gland and be fixed on hermetically sealed case 13 on the casing, place that the stuffing box gland rear end cooperates with stuffing box gland and be fixed on seal 14 on the back cabinet.Between hermetically sealed case and the stuffing box gland, between seal and the stuffing box gland, between seal disc end face and the seal end face refractory seal 15 are housed respectively.The tooth 16,17 of working in coordination is arranged on the end face of seal disc and the seal end face.The tooth 18,19 of working in coordination is arranged on hermetically sealed case and the stuffing box gland.Inflated with nitrogen interface 20 is arranged on the seal.
Should by bolt assembly forward and backward casing, spiral case be connected as one again after connecting the exhaust outlet direction that can conveniently change blower fan after bolt assembly on forward and backward casing, the spiral case is removed the centrifugal blower that makes progress of exhaust outlet or the exhaust outlet as shown in Figure 4 centrifugal blower that is level being changed direction as shown in Figure 3.
