Description
Technical field
The present invention relates to a kind of drying room, specifically refer to cyclone dust removal heat-pump-type drying room.
Background technology
Heated air drier due to technology maturation, adaptable, operating cost is low, reliability is strong, appointing is so one of main preferred unit of dry materials, if in hot-air drying process can and tail heat is effectively reclaimed, then for raising drying efficiency and realize the meaning that energy-saving and emission-reduction all have particular importance.
Blower fan is the key equipment of heated air drier; blower fan is generally centrifugal blower; continuous, stable, the reliably working of blower fan to the hydrofuge of dryer and airflow circulating very crucial; the occasion used due to dryer all contains certain dust mostly; during blower fan work; air-flow by during the draught fan impeller of High Rotation Speed due to centrifugation, dust granule can depart from air-flow phase and deposit and be attached on draught fan impeller.
Because draught fan impeller rotating speed is general all higher, as long as there is micro-dust to exist in air-flow, all more dust can be accumulated after working long hours, thus change the balance of draught fan impeller rotation, if draught fan impeller does not have self purification not clear up in time to dust yet, will cumulative and progressively change draught fan impeller Static and dynamic balance, thus produce vibration.Have the dust that part hardens to be come off by vibration once run into, will balance away from the dynamic rotary of blower fan immediately, then produce judder, this may cause serious personnel and device security accident.
Therefore, if can centrifugal fan impeller be designed, Automatic clearance can be carried out and just do not worry causing dust accumulation, for keeping the reliable and stable work of blower fan and stopping the meaning that security incident all has particular importance.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, provides a kind of simple and practical, the cyclone dust removal heat-pump-type drying room of blower fan energy Automatic clearance dust.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of cyclone dust removal heat-pump-type drying room, comprise drying room, it is characterized in that: the long-shaft fan being provided with Inner eycle in drying room, long-shaft fan comprises major axis and blade, and blade is strip, and blade profile is impeller Axial and radial, the anti-water-drop-shaped of centrosymmetric hollow; Blade two ends are inserted in end plate, and major axis is connected by spoke and fixes end plate; Drying room two ends are respectively equipped with draught hood and enter fan housing, and draught hood connects air-introduced machine, and air-introduced machine is emptying after the evaporimeter that cyclone dust collectors connect heat pump; The evaporimeter of heat pump connects main frame through refrigerant pipe, and main frame connects condenser through refrigerant pipe; The outlet side of air blast connects into fan housing through condenser; Described air-introduced machine comprises draught fan impeller and casing, and draught fan impeller comprises impeller backboard, impeller panel and blade, and blade arrangement becomes impeller Axial and radial, centrosymmetric hollow wedge, and impeller backboard is dish; Hollow wedge blade connects impeller panel and is welded to form impeller bodies with dish-shaped impeller backboard; Impeller panel is provided with air inlet, dish-shaped impeller backboard by the fixing also connection shaft seat of rivet, and axle bed is connected by axis hole and fan shaft; Casing is provided with air inlet and air outlet, cabinet form outline line is involute, the round heart of involute and blower fan axis coinciding, involute is from inside shell air outlet, line radius strengthens gradually with involute circle, terminate outside shell air outlet, shell air outlet width equals involute circumference; Shell air inlet is provided with cover plate, cover plate also has air inlet be convenient to connecting pipe, and axle center and impeller axis coinciding.
Also be provided with end plate in the middle part of described major axis, end plate is passed by blade, strengthens the fastness of long-shaft fan.
Described long-shaft fan has many groups, is arranged in hood.
Described casing is fixed on support.Casing plays sealing process, air inlet air inlet obtains kinetic energy by vane rotary, and carries out power conversion in casing, and a part of kinetic energy is converted to the static energy of gas, make output gas flow have speed dynamic head like this and also have hydrostatic head, both sums are exactly blower press.
Shell air inlet can connect airduct according to need, air inlet cover plate is detachable, be bolted to connection casing, the scroll casing shape of casing is gradually opened profile and is met the needs that Fan casing is airtight, conveying gas realizes energy efficient conversion simultaneously, makes output gas flow can reach required flow and total head.
Described shell air inlet cover plate is bolted to connection casing, and can dismantle.
Drying system is made up of jointly drying room and heat pump, drying room is provided with many group doors and is convenient to material turnover operation, exhausting and blast hood is arranged respectively about drying room, the axial primary air that air-introduced machine and air blast drive forms hallway heated-air drying, top hood UNICOM drying room, arrange in hood and organize long-shaft fan more, promote the airflow circulating of drying room inside, realize rapid highly effective drying.
Long-shaft fan air-out is even, wind-force is mild and blast is less, be particularly suitable for inner air circulation to use, because blade design becomes the centrosymmetric structure of Axial and radial, thus blade is when High Rotation Speed, surface has the centrifugal self purification in powerful surface under powerful centrifugal action, and dust can be separated, cannot adhere to by Quick spin, can not affect dynamic, the static balancing of impeller.
Long-shaft fan blade design becomes hollow symmetrical structure, make blade have very high Wind-Pressure Resistance bend and resist centrifugal bending intensity, also can obtain higher intensity with thinner board making draught fan impeller, be conducive to light and handyization of saving material and facility, ensure to stablize, reliably use; Compared with conventional tile blinds blower fan, there is the outstanding advantages that de-dirt self-purification capacity is strong and intensity is high, adapt to special occasions requirements of one's work.
