Problems solved by technology

When the fan impeller is located in the fan box, in order to avoid friction between the fan impeller and the inner wall of the fan box, it is usually necessary to set the distance between the fan boxes according to the raised height of the impeller cover. The resulting problem is that the fan impeller and the fan box There is a large gap between the inner walls, so when conveying powdery raw materials, the pressure of the fan will be unstable, resulting in unstable movement of the raw materials during the conveying process, resulting in a certain amount of waste. At the same time, the fan impeller and the wind There are large gaps between the inner walls of the chassis, and there will be more pollutants such as carbides in the gaps, which will also have a great impact on the purity of raw materials

Embodiment 1

[0043] Embodiment 1: A kind of blower fan and its manufacturing method for conveying powder raw material, refer to figure 1, including a frame 1, a fan box 2, and a driving motor 3, the fan box 2 is connected to one side of the frame 1 through bolts, and the driving motor 3 is connected to the frame 1 through bolts. The output shaft of the drive motor 3 stretches into the fan box 2 and is connected with the fan impeller 5 through a key connection mode (refer to figure 2 ), the fan impeller 5 is located in the fan box 2.

[0044] refer to figure 1 , The side of the fan box 2 facing away from the frame 1 is provided with an air inlet 21 , and the top of the fan box 2 is provided with an air outlet 22 . During the working process, the drive motor 3 drives the fan impeller 5 (refer to figure 2 ) rotation, the fan impeller 5 generates a strong attractive force during the rotation process, and through the air flow guidance of the fan impeller 5, the material generates a moving ...

Embodiment 2

[0055] Embodiment 2: a kind of fan for conveying powder raw material and its manufacturing method of manufacturing method, its specific steps are as follows:

[0056] First, draw a guide line on the impeller cover 51 according to the shape of the blade 52 , and draw the opening position of the riveting hole 511 according to the position of the riveting piece 521 on the blade 52 . Then, according to the drawn position of the riveting hole 511, the staff uses a punch to punch out the riveting hole 511, and at the same time, the two sides of the riveting hole 511 are smoothed with sandpaper. Take out an impeller cover 51 and put it on the installation platform, insert the riveting piece 521 on the blade 52 into the riveting hole 511, and bend the riveting piece 521 at the same time, so that the riveting piece 521 is pressed on the impeller cover 51.

[0057] Weld the position where the riveting piece 521 is in contact with the impeller cover 51, then fill and weld the gap between...

Abstract

The invention relates to blowers, and aims to provide a blower for conveying powder raw materials and a manufacturing method thereof. According to the technical scheme, the blower is characterized bycomprising a machine frame, a blower box and a driving motor, wherein the blower box is detachably connected to one side of the machine frame, the driving motor is detachably connected to the machineframe, an output shaft of the driving motor extends into the blower box and is connected with a blower impeller, the blower impeller is located in the blower box, an air inlet is formed in one surface, away from the machine frame, of the blower box, an air outlet is formed in the top of the blower box, the blower impeller comprises impeller covers and blades, two impeller covers are oppositely arranged, the blades are located between the two impeller covers, the two surfaces, facing the impeller covers, of each blade are both and fixedly connected with riveting pieces, riveting holes are formed in the impeller covers, and the riveting pieces penetrate through the riveting holes and are bent and pressed on the impeller covers. The blower for conveying the powder raw materials has the advantages of reducing the loss of raw materials and improving the utilization rate of the raw materials.

Description

technical field [0001] The invention relates to a fan, in particular to a fan used for conveying powder raw materials and a manufacturing method thereof. Background technique [0002] During the preparation process of medical drugs, food, chemical industry and lithium battery, when the raw materials are mixed with impurities, the raw materials will be polluted, so it is necessary to use a highly sealed conveying device for transportation. In the prior art, powdery raw materials are usually transported by fans, which have the advantages of high sealing performance and high conveying efficiency, so fans play an extremely important role in many industries. [0003] The fans in the prior art mostly include a fan box, a fan impeller and a drive motor. The fan impeller is located in the fan box, and the output shaft of the drive motor extends into the fan box and is connected to the fan impeller. The machine case rotates to generate air flow, so as to realize the transportation o...
