Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid mixing device applied to continuous mixing of a main agent and a curing agent.

[0002]

[Prior art and its problems]

 Liquid mixing devices that can continuously mix the base compound and the curing agent are known, and various types of structures have already been proposed. However, in the conventional structure, the two liquids are mixed at the end of the continuous mixing operation. In some cases, it may remain in the device and harden, which may cause difficulties in cleaning and recycling the device.

The present invention has been made for the purpose of eliminating such conventional problems.

[0004]

[Means for solving problems]

 The present invention relates to a double pipe structure including an outer pipe part having a closed base end and an open end, and an inner pipe part forming an outer passage between the outer pipe part and an open base end and an inner passage forming a closed end. The base end of the inner pipe penetrates the base closed part of the outer pipe and is connected to the hardener press-fitting part installed outside the pipe, while the base end of the outer pipe communicates with the main passage. A press-fitting part is attached, and the inner and outer passages are communicated with each other through a discharge port provided at the tip of the inner pipe part, and a cylindrical check valve rubber covering the discharge port is attached to the tip part of the inner pipe part. The present invention relates to a liquid mixing device, which is fitted to an outer peripheral portion and further has a static mixer portion connected to a tip of an outer pipe portion.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As is apparent from FIG. 1, the device of the present invention includes an outer tube portion 1 having a proximal end closed and a distal end opened, and a proximal end opening combined with the outer tube portion 1 to form a double tube. An inner pipe portion 2 having a closed tip is provided, and an outer passage 3 is formed between the inner and outer pipe portions 1 and 2, and an inner passage 4 is formed in the inner pipe portion 2.

The base end portion of the inner pipe portion 2 penetrates the base end closed portion 11 of the outer pipe portion 1 to project outside the pipe, and is connected to the hardening agent press-fitting pipe 5 at the protruding portion 21.

A base material pressure inlet 12 communicating with the outer passage 3 is integrally provided at the base end portion of the outer pipe portion 1, and is connected to the base material pressure inlet pipe 6 at the pressure inlet 12.

As the press-fitting pipes 5 and 6, flexible ones, for example, rubber hoses are used.

The inner and outer passages 4 and 3 are communicated with each other through a discharge port 7 formed at the tip of the inner pipe section 2, and on the outer peripheral surface side of the inner pipe section 2 so as to cover the discharge port 7. A cylindrical check valve rubber 8 is fitted.

The portion of the check valve rubber 8 is shown in an enlarged manner in FIG. 2, and the check valve rubber 8 is fixed to the outer peripheral surface of the inner pipe portion 2 at the base end side by applying an adhesive 9, for example. When pressure is applied from the surface side, as shown by the phantom line in the figure, it opens in a trumpet shape against the resilience and makes the inner passage 4 communicate with the outer passage 3. Return to the closed state shown by the solid line, and shut off the inner and outer passages 4, 3.

A static mixer section 10 is connected to the tip of the outer tube section 1 via a tapered section 13, and a hose 102 for delivering a mixed solution is attached to the tip of the mixer section 10 via a nozzle 101. There is.

According to the device of the present invention, the main agent is supplied from the press-fitting pipe 6 through the pressurizing port 12 into the outer passage 3, while the curing agent is supplied from the press-fitting pipe 5 through the inner passage 4 and the discharge port 7 to the check valve rubber. 2 is fed into the outer passage 3 while pushing open as shown by the phantom line in FIG. 2, and the two liquids are connected from the tapered portion 13 at the tip of the outer cylinder portion 1 to the inside of the static mixer portion 10. Then, the mixture of the two liquids can be continuously sent from the tip of the mixer section 10 to the consuming section through the nozzle section 101 and the delivery tube 102.

After the mixing operation is completed, when the supply of the curing agent is stopped, the check valve rubber 8 returns to the closed position shown by the solid line in the figure due to the elasticity of the check valve. Completely blocked by rubber 8.

When the main agent is continuously supplied in this state for a while, the two-liquid mixture remaining in the outer passage 3 and each part communicating with the outer channel 3 is entirely replaced with the main agent. When the supply of the main agent is stopped after the replacement, the curing agent remains in the inner passage 4 side and the main agent remains in the outer passage 3 side in a completely isolated state. Since the main agent and the curing agent do not cure by themselves, they can be easily washed off by washing.

In the present invention, as the combination of the main agent and the curing agent, the combination of the resin-based main agent and the curing agent in the two-component reaction curing type resin adhesive, and other recently, the water shielding and surface protection of underground structures. A combination of a main agent (asphalt emulsion + cement or cement or asphalt emulsion + cement + filler + auxiliary agent) and a hardening agent (super absorbent polymer), which has been attracting attention as a grouting material for erosion prevention, etc. It can be illustrated.

[0017]

【effect】

 According to the device of the present invention, the check valve rubber can completely shut off the inside and outside passages at the end of the mixing operation, so that the two-liquid mixture can be completely discharged from the inside of the device, and the cleaning and regeneration can be easily performed.
