High pressure pump impeller

  The devices listed in the documents [0005] by the inventor are devices related to combustion, which can be called a high-pressure blower, but have been used for the ring prower.

  However, among the fields related to combustion, the ring flower was timely for counterflow airflow, but it is a combustion method means for improving the efficiency of heat exchange described in Patent Document 5, which is the foundation. Is absolutely necessary to obtain the expected event. For this purpose, it is usually necessary to improve the chimney function, but it is necessary to increase the equipment cost in terms of equipment. However, there is a method of selecting a banturistic rubber mechanism as one means for avoiding this, and a specific improvement device has been proposed.

The improved venturi scrubber is an attracting function for exhausting exhaust gas into the chimney, and the improved device results when the high-pressure air is diffused and the suction cross section is enlarged.
Although the improvement of the jet part is proposed in Patent Document 8, since the high-pressure blower is expensive in the existing machine (turbo fan), the improvement remains as a problem, and its solution is the goal of the present application, It is also an issue.

Means to solve the problem

  The high-pressure air discharge function blower aimed at by the present application is an improved apparatus that maintains and reinforces the strong suction negative pressure of the conveying fan as disclosed in Japanese Patent Application No. 2711402 and converts it into discharge force.

  The fan is significantly fixed to a circular plate in which a rotating impeller built in a normal fan caning is fixed to a rotating shaft with a one-dimensional blade blade having a significant length and width based on a synthetic sine curve, Is an open structure with an edge, and the intake of the canning is not in contact with the blades. Accordingly, the suction negative pressure at the suction port generated with the rotation of the impeller has a relationship of being decompressed and discharged in the caning. However, it was satisfied with its ability to convey rough objects (cutting straws, momigara), which was originally intended, and was equipped with a suction negative pressure that was much more efficient than previous similar-purpose conveyors. The power was great.

Based on the basis of the previous paragraph, the process for realizing a blower that enhances the discharge force of the present application is as follows.
a. A plurality of blades having a significant combination of composite sinusoidal keynotes are bonded to a flange and a side plate fixed to a combination rotation shaft.
b. When the diameter of the impeller is determined, the length of the blade is also determined c. The diameter of the fixed disk that determines the center is also determined, but the width of the blade blade is wide at the incident point position and tapered two-dimensionally toward the outer peripheral edge, so the fixed plate also becomes one-tuned accordingly, and the rotation axis The one end surface of the blade blade is fixed to the flange connected to the blade.
d. A target side plate of the same shape with the suction port opened is attached to the target end face of the blade blade fixedly bonded to the side plate fixed to the flange, and the outer periphery of the impeller is opened. The opened inlet has a structure closely related to the casing inlet.
e. The casing structure also has a tapered outer periphery similar to the shape of the impeller, and the discharge port is also narrower than the suction port. The casing suction port is in close contact with the impeller suction port,

The functions of the impeller completed in the above process are as follows.
The air sucked in by the negative pressure generated with the rotation of the impeller has a suction negative pressure.
Flow is made inertial by the set impeller, but the outer peripheral end of the impeller is wide open, so the pressure decreases in the normal one-dimensional shape blade, but the blade blade of the specification of this application is tapered In this case, the basket gap between the blades is tapered and less diffused, and the pressure caused by the inertia of the rotating centrifugal flow is increased. Therefore, the air density is compressed and the pressure discharged to the discharge port is the suction negative pressure and the repulsive force of the pressurized air. It becomes the function which this application aimed at.

The invention's effect

  The function realized by the order of the terms reaches the goal of the term (0010) aimed by the present application. Since the negative pressure of the combustion heat exchange furnace required by the inventor can be realized at the lowest cost, it is not limited to the effect of promoting the field, but when the target combustion apparatus becomes larger, a small-scale blower However, fields that can contribute to the advancement of industrial equipment that can be used, such as being able to be replaced with a ring crawler, will expand.

BEST MODE FOR CARRYING OUT THE INVENTION

  Although the present invention has a function of high pressure and a large air volume, this mechanism device has been a blind spot of the previous model, so the basic factors are verified, and the completeness is gathered from the public knowledge to improve the good function. It is desirable to create a system that enhances

  Since the function based on the above configuration is described in (0016), it will be omitted, but the main point is that the blade blade shape is tapered and the bucket surrounded by the both side plates compensates for the degree of openness between the blade blades opened to the outside. In the structure where the volume is close to leveling, the intake air diminishes the air density by the negative pressure generated by the strong centrifugal flow inertia accompanying the rotation of the impeller, but the discharge air is pressurized by the rotational flow inertia force and the taper impeller characteristics. As a result, the degree of pressure increases, the repulsive force is added to the negative suction pressure, and the discharge force increases.

As described above, the inventor decided on the subject from the face-to-face environment in which a combustion means for obtaining effective radiant heat was sought. The contribution to the completion of the mechanism for obtaining the desired event is linked to the contribution to energy saving and environmental conservation. The ring blower-type machine can be used in many other fields, so it is possible to contribute by increasing the degree of perfection. This is one of the beginnings.
