Description

Technical Field

[0001] The utility model relates to the technical field of blowers, in particular to a double-air outlet blower. Background Art

[0002] Since the impeller of the blower rotates frictionlessly inside the body and does not require lubrication, the blower makes the exhausted gas oil-free, making it an ideal pneumatic conveying gas source for industries such as chemical and food. The blower is a volumetric operation blower. When in use, the flow rate changes very little with changes in pressure, but the flow rate changes with the speed. The blower has the advantages of safe operation and long service life, and is therefore widely used in the transmission of industrial gas sources.

[0003] However, the traditional blower has only one air outlet, and the air volume and wind pressure are small and the noise is large when in use, which affects the air outlet efficiency. The patent announcement number CN215890513U discloses a dual-air outlet DC blower, including an upper fan shell, a lower fan shell and a fan blade structure that generates airflow, the mounting end of the upper fan shell is provided with a buckle with a convex structure; the mounting end of the lower fan shell is provided with a buckle hole corresponding to the buckle, the lower fan shell and the upper fan shell are provided with an air outlet channel corresponding to the air outlet direction of the fan blade structure, and the air inlet end of the air outlet channel is provided with an inclined air outlet, the center of the lower fan shell is provided with a gear shaft for mounting the fan blade structure, the axis of the fan blade structure is installed in the center of the lower fan shell through the gear shaft, the upper fan shell is buckled with the buckle hole of the mounting end of the lower fan shell through the buckle, and the fan blade structure is arranged between the upper fan shell and the lower fan shell;

[0004] Although the dual-outlet DC blower has two outlets arranged on the upper shell and the lower shell corresponding to the fan blades, which can increase the efficiency of the blower's air volume and air pressure, reduce the blower's operating noise, and improve the blower's use efficiency, the air outlet diameter of the air outlet is larger than the diameter of the air outlet channel. When the wind is output, most of the wind is output through the air outlet, while only a small amount of wind is output through the air outlet channel, resulting in unbalanced wind source delivery, which affects the balance of air source delivery through the blower and the air source output;

[0005] Therefore, the utility model provides a double-air outlet blower which outputs the blower airflow evenly. Summary of the invention

[0006] The utility model aims to provide a double-air outlet blower to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A double-outlet blower comprises a lower shell, a turbine blade arranged in the lower shell, and an upper shell which cooperates with the lower shell to cover the turbine blade, wherein the axis of the lower shell is provided with a vertical support shaft, the base of the turbine blade axis is butted against the support shaft, and is connected to the connection end at the top of the support shaft through a bearing seat at the top of the base;

[0009] The groove inside the upper shell covers the turbine blades and is fixed to the lower shell. The upper shell and the lower shell are provided with a first air outlet and a second air outlet corresponding to the air outlet direction of the turbine blades. The first air outlet and the second air outlet are relatively inclined and have the same diameter.

[0010] Furthermore, corresponding connecting ears are respectively provided on the outer side walls of the lower shell and the upper shell, and the lower shell and the upper shell are fixed by bolts passing through the connecting ears. After the turbine blades are installed on the supporting shaft of the lower shell, the upper shell covers the lower shell, and the bolts pass through the connecting ears to lock the upper shell and the lower shell into one, so that a space for assembling the turbine blades is formed between the upper shell and the lower shell, which is used to cooperate with the rotation of the turbine blades to generate wind flow in the space formed between the upper shell and the lower shell and output it through the first air outlet and the second air outlet.

[0011] Furthermore, an air inlet is provided above the upper shell for leaking out the turbine blades and cooperating with the air intake. The power for promoting the rotation of the turbine blades is input through the air inlet to cooperate with the rotation of the turbine blades to form a wind flow.

[0012] Furthermore, the bottom end of the support shaft is fixedly connected to the axis of the inner bottom surface of the lower shell, and the support shaft cooperates with the turbine blades to be limited between the lower shell and the upper shell and cooperates with the turbine blades to rotate in the space between the upper shell and the lower shell.

[0013] Furthermore, the inclined angle between the first air outlet and the second air outlet is less than 30°.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The double-outlet blower has a first air outlet and a second air outlet correspondingly arranged on the upper shell and the lower shell to cooperate with the output of the turbine blades, and the first air outlet and the second air outlet are inclined and have the same diameter, so that the first air outlet and the second air outlet output an equal amount of wind flow into the pipe of the output air source, and the wind flow output by the first air outlet and the second air outlet is reflected on the inner wall of the pipe, so that the wind flow is output to the air source in an "8" shape circulation state after the reflection, thereby achieving the purpose of coordinating with the air source to output a large amount of air.
