Description

Technical Field

[0001] The utility model belongs to the field of explosion-proof blowers, in particular to an explosion-proof high-pressure blower. Background Art

[0002] With the continuous development of the economy, people use blowers in more and more scenarios and machines, and blowers are slowly entering people's lives. Since the impeller of the blower runs frictionlessly inside the body and does not require lubrication, the discharged gas does not contain oil. It is an ideal pneumatic conveying gas source for industries such as chemical and food. The blower is a volumetric operation blower.

[0003] The existing technology has specially developed some explosion-proof high-pressure blowers. For example, the Chinese patent with the announcement number "CN219119507U" announced "an explosion-proof centrifugal blower impeller device". The front disk is fixedly connected to the motor. At the same time, the front disk is made of fiberglass, which can effectively avoid the long-term friction between the impeller and the side wall of the front disk to generate electric sparks, thereby causing dust explosions, effectively improving the explosion-proof performance of the impeller. The blades are rotatably connected to the front disk, so that the blades can work on the air, thereby generating air volume and wind pressure, effectively improving the efficiency of the blower in generating air volume.

[0004] Although the front disk can be fixedly connected to the motor, and the front disk is made of fiberglass, it can effectively avoid the sparks generated by long-term friction between the impeller and the side wall of the front disk, thereby causing a dust explosion, but in certain specific occasions, the blower will be used for a day or longer, which will cause the blower motor to heat up, and to a certain extent, the blower motor will be damaged and its service life will be greatly reduced. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide an explosion-proof high-pressure blower to solve the problems of explosion-proof blowers.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] The transmission gear of the present invention is a gear which is connected with the gear of the driven gear to the gear of the driven gear. The gear of the driven gear is connected with the gear of the driven gear to the gear of the driven gear. When the gear of the driven gear is turned, the transmission gear of the gear is turned, and the rotation of the gear of the driven gear is performed along the axis of rotation of the driving motor of the driving motor.

[0008] As a preferred technical solution, a support seat is fixedly installed on the upper end of the base, and an explosion-proof shell is fixedly installed on the upper end of the support seat.

[0009] As a preferred technical solution, a mounting ring is fixedly installed at one end of the explosion-proof shell, a plurality of connecting rods are fixedly installed inside the mounting ring, and the circular shell is fixedly installed at one end of the connecting rod.

[0010] As a preferred technical solution, the rotating shaft passes through one side of the explosion-proof shell and is fixedly connected to the fan blades, and the output rod also passes through one side of the explosion-proof shell and extends into the interior of the circular shell.

[0011] As an optimal technical solution, a second belt is connected to the interior of the first driving wheel, and the end of the second belt away from the first driving wheel is installed inside the second driving wheel. The first driving wheel drives the second driving wheel to rotate through the second belt.

[0012] As a preferred technical solution, a limit block is fixedly installed on the bottom of the driving motor, and an output rod is rotatably installed inside the limit block.

[0013] As a preferred technical solution, a first belt is installed inside the first rotating wheel, and the end of the first belt away from the first rotating wheel is installed inside the second rotating wheel. The first rotating wheel drives the second rotating wheel to rotate through the first belt.

[0014] As an optimal technical solution, a bearing is fixedly installed on one side of the interior of the explosion-proof shell, one end of the rotating rod is fixedly installed on the inner ring of the bearing, the end of the heat dissipation leaf away from the rotating rod is fixedly installed with a fixed block, the upper end of the fixed block is fixedly installed with a support rod, and the end of the support rod away from the fixed block is fixedly installed on the upper end of the interior of the explosion-proof shell.

[0015] As a preferred technical solution, the explosion-proof shell is provided with a plurality of air inlets at one end away from the circular shell, and the explosion-proof shell is provided with a plurality of vents on both sides of one end close to the circular shell.

[0016] In summary, the present invention has the following beneficial effects:

[0017] The first step is to start the driving motor so that the rotating shaft fixedly installed at one end of the driving motor rotates. Since a first driving wheel is integrally formed on the outer ring of the rotating shaft, and a limit block is fixedly installed at the bottom of the driving motor, an output rod is rotatably installed inside the limit block, and a second driving wheel is integrally formed on one end of the output rod close to the fan blade. A second belt is connected and installed between the first driving wheel and the second driving wheel. In this way, when the driving motor drives the rotating shaft to rotate, the first driving wheel will drive the second driving wheel to rotate through the second belt, so that the output rod rotates, and the cooling fan is driven to rotate under the rotation of the output rod, so that the cooling fan can be driven to rotate, which can effectively cool the driving motor and effectively reduce the overheating of the driving motor, which will cause the service life of the driving motor to be shortened.

[0018] Second, multiple air inlets are provided inside the end of the explosion-proof shell away from the circular shell. The cooling fan can draw outside air into the explosion-proof shell through the air inlets and then blow it onto the shell of the drive motor, so as to cool the drive motor. Ventilation holes are provided on both sides of one end of the explosion-proof shell close to the circular shell. The ventilation holes can discharge the air inside the explosion-proof shell to circulate the air, which is beneficial to the heat dissipation of the drive motor. BRIEF DESCRIPTION OF THE DRAWINGS
