Abstract

(57) [Summary] [Objective] It is an object of the present invention to provide a pump device having a simple structure, facilitating assembling / disassembling and maintenance management, and having a high fluid feed efficiency. [Structure] A plurality of blade vanes are symmetrically arranged on the inner wall surface of the tubular body, and the vane tubular body having the vane blades is interposed between the other feeding and sending side tubular tubes and is independent from the outside of the tube. It is characterized in that it is configured to be driven to rotate.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fluid feed pump device.

[0002]

[Prior art]

 In the conventional configuration, the impeller is attached to the rotary shaft exclusively in the casing.

[0003]

[Problems to be solved by the device]

 Since the impeller is attached to the rotating shaft, the structure becomes complicated, and the effective cross-sectional area inside becomes small, so that the effective feed amount cannot be large.

[0004]

[Means for Solving the Problems]

 In view of the above, the present invention has a plurality of vane blades symmetrically arranged on the inner wall surface of the tubular body, and interposes the vane tubular body having the vane blades with the other feeding and feeding side tubular barrels. It is characterized in that it is configured to be independently driven to rotate.

[0005]

[Action]

 The device of the present invention has a simple structure and a substantial effective feed amount due to the above construction.

[0006]

【Example】

 1 is a sectional view of the device of the present invention, and FIG. 2 is a sectional view taken along line XX of FIG. Reference numeral 1 is a tube tube on the feed side, 2 is a tube tube on the feed side, and 3 is a tube tube in which a plurality of (two in the illustrated example) blades 3a and 3b are symmetrically arranged on the inner wall surface of the tube tube 3 interposed therebetween. A gear 4 is attached to the center of the outer circumference of the vane tube.

[0007] Reference numeral 5 denotes a joint case which is formed by splitting left and right sides 5a and 5b by interposing a vane tube cylinder 3 between the tube cylinders 1 and 2 on the feed-in and feed-out sides to form a joined state. At the same time, the inside of either the left or right box (5b in the illustrated example) is engaged with the gear 4 and the gear 4 to form an empty chamber 7 in which a gear 6 for rotationally driving the gear 4 is housed. Become.

Numerals 8a and 8b are ball bearings for rotatably supporting the blade tube cylinder 3 with respect to the joint case 5, and 9 is a ball bearing for similarly rotatably supporting the gear 6 and 10a. And 10b are O-rings for sealing at the joints. Reference numeral 11 is a bolt screw for fastening and fixing the left and right split casings 5a and 5b.

In the above-described structure, by driving the gear 6 by an external motor (not shown), the blade tube barrel 3 is rotated at high speed through the gear wheel 6. At this time, in the blade tube barrel 3. The fluid is pushed out from the inlet side to the outlet side by the propulsive force caused by the twisting of the blades. Here, the term “fluid” means a gas, a liquid, a granular material, and the like.

In the above embodiment, two blades in the blade tube cylinder 3 are shown, but the number of blades is increased, the blades are provided with a phase difference, or the blades are arranged at positions separated by a certain distance. It can also be designed to work.

[0011]

[Effect of device]

 According to the device of the present invention, since the rotary shaft is not required at the center, the effective cross-sectional area in the tube becomes large and the effective feed amount becomes large. Moreover, the whole structure is simple and the assembly and disassembly are easy, and the transportation and maintenance management can be performed efficiently.
