Description
Technical Field
The invention relates to the technical field of cooling of blowers, in particular to a suspension bearing blower with a single air inlet and a cooling fan driven by a main working motor.
Background
The suspension bearing blower is a new generation of efficient and energy-saving blower product, is widely applied to multiple industries such as sewage treatment, textile, food and medicine, conveying and the like, and belongs to important core equipment. The fan products account for about 10% of national power consumption, and belong to large power consumers. When the suspension bearing air blower is used, components such as a high-speed motor, a frequency converter and a reactor can emit a large amount of heat, and if the heat cannot be well removed, the high-speed motor, the frequency converter and the like can be broken down and damaged. Failure of suspension bearing fan damage due to improper cooling has been a major source of failure.
The cooling modes of high-speed motors, frequency converters, reactors and other high-heat-dissipation components of the suspension fan are subjected to several technical development stages. The earliest method is to discharge heat out of an integrated cover of a fan by adding independent external cooling fans to a high-speed motor, a frequency converter, a reactor and the like (currently, a suspension bearing blower is a highly integrated automation device, and a main machine head, the frequency converter, a control system and an electrical system are integrated in one integrated cover), and because the number of the independent fans is large and is more than 5, once one fan fails, a problem of one cooling element can be caused, and the whole fan can also fail. Moreover, the independent fans consume a lot of electric energy, and the efficiency of the fan is reduced. The number of air inlets (containing cooling air) of the suspension bearing blower at the stage is 2 or more, and each air inlet needs to be additionally provided with a filter and filter cotton. Install negative pressure sensor again in whole integrated cover, in case the filtration cotton of air intake is blockked up by the dust, will report to the police, the workman can change the filtration cotton this time, nevertheless the workman only can change the main air intake filtration cotton occasionally (inside pressure differential also can resume this time, system alarm also can be relieved), and the filtration cotton of other inferior air intakes can not be changed for a long time, and these inferior air intakes often are responsible for components and parts cooling such as converter, just arouse the converter trouble easily this time. The fault of any heat dissipation component can cause the fault of the whole suspension bearing fan, which is the main reason that the fault rate of the suspension bearing fan is high.
Disclosure of Invention
The invention aims to solve the problems of poor heat dissipation effect and overlarge energy consumption caused by a plurality of air inlets and a plurality of fans in the prior art, and provides a suspension bearing blower for driving a cooling fan by a single air inlet and a main working motor.
In order to achieve the purpose, the suspension bearing blower with the cooling fan driven by the single air inlet and the main working motor comprises an integrated cover and is characterized in that the integrated cover is provided with an inner cavity and an outer cavity, a host is arranged in the inner cavity of the integrated cover and comprises a high-speed motor, a working impeller, a cooling impeller and a volute, wherein the working impeller is installed at one end of the high-speed motor, and the cooling impeller is installed at the other end of the high-speed motor; a communicating air duct is arranged between the inner cavity and the outer cavity of the integrated cover; a unique air inlet is arranged between the integrated cover outer cavity and the inner cavity and is used for working air inlet and cooling air inlet of the fan; the integrated cover outer cavity is provided with a wind path, and a frequency converter and electronic components are arranged on the wind path.
Preferably, the integrated cover is further provided with an external air inlet, and one side of the external air inlet is provided with filter cotton.
Preferably, the wind coming from the external air inlet passes through the electrical element and is discharged out of the integrated cover by the working impeller and the cooling impeller after taking away heat.
Preferably, only one motor is rotating when the fan is operating.
Preferably, the air drawn by the cooling impeller is separately exhausted from the integrated shroud.
Preferably, the air drawn by the cooling impeller is discharged into the working impeller intake.
Compared with the prior art, the invention has the advantages that: the air inlet and the filter are adopted, a cooling radiating fan driven by an independent motor is omitted, components such as a high-speed motor, a frequency converter and a reactor can be well cooled through ingenious technical arrangement, and the problem that workers forget to replace secondary air inlet filter cotton to cause the fault of the radiating components and the fault of a fan caused by the fault of the independent cooling fan can be solved.

Detailed Description
The present invention is further described below in conjunction with the following drawings, the structure and principle of which will be apparent to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the invention relates to a suspension bearing blower with a cooling fan driven by a single air inlet and a main working motor, which comprises a blower core host (comprising a high-speed motor, an impeller and a volute), an integrated cover, filter cotton, a frequency converter, electrical components and control elements.
The invention has the advantages of ingenious and reasonable design, and the working impeller is arranged at one end of the high-speed motor for compressing air, and the cooling fan impeller is arranged at the other end of the high-speed motor for compressing air. Once the high-speed motor starts to compress air, the impeller of the cooling fan also starts to work, the working impeller and the cooling fan can suck a large amount of air, the air can enter the integrated cover from the only air inlet, external cold air is filtered and purified at the filter cotton part of the air inlet, the external cold air firstly passes through the frequency converter and some electronic components (reactors and the like) to take away heat of the frequency converter and the electronic components, a part of the air entering from the outside is compressed by the working impeller and is exhausted out of the fan for production, and the rest air flows through the rotor and the stator of the high-speed motor due to the suction of the cooling impeller and takes away the heat of the rotor and the stator of the motor and is exhausted out of the integrated cover. The design ingeniously drives the two impellers through only one motor, the compression of working gas and the suction and discharge of cooling gas are completed, and the gas compression and the cooling of heat dissipation components are completed. In addition, only one air inlet and one filter are arranged, so that the problem that workers forget to replace part of the air inlet filter cotton is solved. If the fan is assisted by another full-automatic filter cotton replacement technology, the long-term maintenance-free suspension bearing fan can be completely realized.
