JPS5841898B2 - Inhalation device for soft substances - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inhalation device for a soft substance, such as a long soft substance or a membrane-like soft substance.

When attempting to collect a substance by suctioning it into the suction tube with an inhalation device that uses negative pressure, if the substance is a long soft substance, the inside of the suction tube is continuously narrowed by the soft substance, which reduces the suction force. decreases, making it impossible to suction and collect.

Furthermore, if the substance is larger than the diameter of the opening at the tip of the inhalation tube, such as a film-like soft substance, the opening at the tip of the inhalation tube will be blocked by the soft membrane-like substance, and the inhalation device will not work properly. It stops working.

In view of the above-mentioned drawbacks of an inhalation device that uses negative pressure, this invention provides a rotating front blade and an external fluid suction port in the opening at the tip of the inhalation tube to shear long soft materials or film-like soft materials. This is an inhalation device for a soft substance that is continuously inhaled and collected while being crushed.This embodiment will be described below with reference to the drawings.

1 and 2 show an inhalation tube 1 of this inhalation device.

The suction pipe 1 is composed of a main pipe 2, an outer pipe 3 screwed onto one end of the main pipe 2, and a rotary cylinder 5 rotatably supported inside the outer pipe 3 via a rolling bearing 4. be done.

The main tube 2 is made of a flexible material except for the threaded part 6 and has a predetermined length, so that the opening T of the outer tube 3 can be moved close to or in contact with a desired location.

In addition, the other end of the main tube 2 is a collection container (
Negative pressure generator (not shown) of the inhalation device (not shown)
connected to.

A large number of rotating blades 8 are installed on the inner circumferential surface of the rotating cylinder 5 with a twist angle in the axial direction. An intake port 9 is provided.

Reference numeral 10 denotes a rectifying tube fixed to the tip of the rotary blade 8, which allows air to flow along the rotary blade 8.

A plurality of curved surfaces of the sheathing tube 3 are located at positions in the circumferential direction of the sheathing tube 3 corresponding to the air intake ports 9 and spaced a predetermined distance from the open lower end face in the axial direction so as to prevent soft substances from being sucked in. A suction port 11 for air existing outside the suction pipe 1 is provided at a location.

With the above configuration, when the inside of the suction pipe 1 is made negative pressure by the negative pressure generator, the outside air is transferred to the suction port 11 and the air intake port 9.
The water flows through the tube and flows into the main tube 2 along the rotary blades 8, whereby the rotary cylinder 5 rotates with a predetermined rotational torque.

Reference numeral 12 denotes a rotating front blade which is integrally formed with the rotating cylinder 5 in front of the rotating blade 8, and is rotated by the rotating blade 8 to shear and crush the soft material sucked in from the opening I of the outer tube 3.

The rotating front blade 12 has a sharp edge in the direction of rotation when it is mainly used for shearing soft materials, and has a large helix angle when it is used mainly for crushing.

Furthermore, if it is desired to extend the life of the rotating front blade, it can be shaped separately from tool steel or the like and integrally attached to the rotating cylinder 5.

A fixed front blade 13 is fixed to the exterior tube 3 with a predetermined gap provided in front of the rotating front blade 12, and is provided to sandwich soft materials between the rotating front blade 12 and shear and crush them efficiently.

This fixed front blade 13 is useful when the rotating front blade 12 rotates at a relatively low speed, and can be omitted when the rotating front blade 12 rotates at a high speed and the soft material can be sheared and crushed by its kinetic energy alone. can.

Reference numeral 14 denotes a thruster bearing which receives a thrust load acting on the rotating cylinder 5 during shear crushing of a soft material, and is interposed between the rotating cylinder 5 and the main tube 2.

Reference numeral 15 denotes an adjustment ring loosely fitted to the exterior pipe 3, which has the same number of adjustment windows 16 as the air intake ports 9 in the circumferential direction, and which allows air to flow into the main pipe 2 from the air intake ports 9. Adjust amount.

In other words, the adjustment ring 15 compensates for the decrease in the suction force of the open lower case caused by the provision of the air intake port 9, and throttles the air intake port 9 when the soft material requires suction force.

Next, the operation of sucking and collecting a long soft substance or a film-like soft substance using this suction device will be explained.

First, the end surface of the opening 1 of the suction pipe 1 is brought into contact with or close to the surface of a soft substance, and the inside of the suction pipe 1 is made to have a negative pressure by the negative pressure generator.

Next, the adjustment ring 15 is rotated according to the properties of the soft material to adjust the suction force of the opening lower and the shearing and crushing force of the rotating front blade.

After doing so, the soft material is sucked into the suction tube 1 and collected in the following manner.

That is, in the case of a long soft substance, when it is sucked in through the open lower part, it is sheared and crushed into appropriate lengths by the rotating front blade 12 and the fixed front blade 13.

Therefore, the soft substances do not remain long inside the suction pipe 1 forever, but are sequentially collected in the collection container starting from the ones that have been sheared and crushed.

Next, in the case of a film-like soft material, the open lower is temporarily blocked by the soft material, but the air outside the suction pipe 1 enters the suction pipe 1 through the suction port 11 and the air intake port 9. Therefore, even if the opening is temporarily blocked, the rotating front blade 12 continues to rotate.

When the film-like soft substance is absorbed up to the front surface of the rotating front blade 12 by the suction force, a part of the film-like surface is sheared.

As a result, a space is formed on the back side of the membrane-like soft material, and after that, this membrane-like soft material is drawn and inhaled, sheared into an appropriate size, and stored in a storage container in the same manner as described above. do.

FIG. 3 shows another embodiment of the present invention, in which the rotary front blade 11 is driven to rotate by a drive device 19 instead of being rotated by external fluid sucked in through the suction port 18.

As explained above, the present invention relates to an inhalation device for a soft substance, which has a rotating front blade and an external fluid suction port in the tip opening of a suction tube, and the invention relates to an inhalation device for a soft substance, such as a long soft substance or a film-like soft substance. It can also be easily inhaled and collected while shearing and crushing.

Therefore, it becomes very easy to remove soft substances that adhere to or form on objects, for example, to inhale and remove internal substances from fish bodies, chicken bodies, donated bodies, etc.
