Abstract
The utility model discloses a vacuum exhaust fan which is mainly composed of a support, a motor, a power shaft, fan blades, bearings, and sealing pads. One end of the support is an air inlet, while the other end is an air outlet. The upper part of the support is connected with the fixedly mounted motor. The power shaft of the motor penetrates through the support and enters into the interior of the support. The front end of the power shaft is provided with the fan blades. The power shaft and the support are fixed through the bearings. The gaps between the power shaft and the support are sealed by the sealing pads. The vacuum exhaust fan is low in price and low in operation expense and is used for supporting the use of vacuum drying equipment. The vacuum exhaust fan is mounted between vacuum equipment and cooling equipment in a manner that the air inlet is connected to the vacuum equipment while the air outlet is connected to the cooling equipment. The vacuum exhaust fan increases the displacement of composite gas, the size of which is reduced by 3-20 times after being cooled by the cooling equipment. The small power vacuum set can achieve the usage effect equal to that of the large power vacuum set. The equipment purchase cost is reduced and the operation expense is lowered.
Description
Technical field
The utility model relates to a kind of air bells exhauster, specifically matching used vacuum air bells exhauster on vacuum dryer.
Background technique
In the processing fields such as grain, food, chemical industry, medicine, often need under vacuum condition, to material, be dried processing, to reach the material of necessary requirement water content standard; At present, conventional vacuum drying scheme is directly connected with vacuum equipment with vacuum unit exactly, by vacuum unit, vacuum equipment inside is vacuumized, and needs very powerful vacuum equipment just passable; Vacuum air bells exhauster present on market has Roots's air bells exhauster, and use is single, and cost is very expensive, running expense is high.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiency that prior art exists, provide a kind of on drying equipment matching used vacuum air bells exhauster, its low cost, running expense are low, can increase steam-laden gas discharge capacity and carry out cooling processing, improve the work effect of vacuum unit.
In order to arrive above-mentioned purpose, the utility model is achieved through the following technical solutions: a kind of chief component equipment of vacuum air bells exhauster is: support, motor, line shaft, fan blade, bearing, sealing gasket;
1, one end of support is intake grill, and it is flanged joint; The other end is exhaust outlet, and it is flanged joint;
2, the motor that is connected and fixed above installation of support, motor is general motor;
3, the line shaft of motor enters inside through between support, and the front end of line shaft is installed with fan blade;
4, line shaft and support are supported fixing by bearing;
5, the space between line shaft and support is sealed by sealing gasket; Sealing gasket is vacuum-resistant, wear-resistant sealing gasket;
6, vacuum air bells exhauster is that matched with vacuum drying equipment uses, it is arranged between vacuum equipment and cooling equipment, intake grill one end of vacuum air bells exhauster is connected to vacuum equipment by connecting tube, one end of exhaust outlet is connected to cooling equipment by connecting tube, and connection set is fixed by the screw of screw port;
7, actuating motor, the line shaft of motor drives fan blade, and vacuum air bells exhauster is cooled to after water, gas by cooling equipment after the moist composite gas in vacuum equipment is extracted out, and water is discharged in atmosphere by vacuum unit by water storage tank discharge, gas.
?the utility model has following beneficial effect: vacuum air bells exhauster low cost, running expense are low, a kind of vacuum air bells exhauster has increased the air displacement of composite gas, the air-breathing workload that vacuum unit has reduced, thereby the small-power vacuum unit of configuration just can reach the using effect of high-power vacuum unit, the equipment purchase cost that reduces vacuum unit, has reduced vacuum drying running cost cost.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
