Description

[Detailed Description of the Invention] This invention relates to a cleaning device for milking tools used for milking cows, goats, etc., and particularly to a cleaning device for cleaning by circulating a cleaning fluid.

A milking cylinder is connected to the end of a milking hose, and the equipment must be cleaned after milking a cow or goat.

Conventionally, one end of a milking hose was connected to a vacuum tank, and the tip of the milking tube was soaked in a cleaning solution several times, and the cleaning solution was sucked in to clean it.

Depending on this method, the milking hose and milking cylinder cannot be thoroughly cleaned, which tends to result in unsanitary conditions.Additionally, the milking hose and milking tube must be periodically disassembled and deposits removed using a brush, etc., making handling extremely time-consuming. There were drawbacks.

This invention allows milking equipment to be cleaned more easily and more completely, and furthermore, it does not require expensive parts and the vacuum pump used for milking can also be used as a power source for cleaning. To provide a cleaning device for milking tools that can reduce the overall cost.

Examples of this invention will be described below based on the drawings.

The milking tool cleaning device shown in FIG. 1 includes a water absorption tank 1, a check valve 2, and a reflux pipe 3.

The water absorption tank 1 has a cylindrical overall shape, and has an intake port 4 and an exhaust port 5 at the upper end, a drain port 6 and a water outlet 7 at the lower end, and a water intake port 8 in the middle.

The exhaust port 5 is opened at the upper end of the suction tank so that the air in the suction tank 1 can be exhausted by the vacuum pump 9 connected thereto, and the water intake port 8 is opened at the upper end of the suction tank so that the air in the suction tank 1 can be exhausted by the vacuum pump 9 connected thereto. The water absorption tank 1 is preferably opened at the top so that the bubbles can circulate the cleaning liquid more effectively.

However, if the water suction port 8 is located above the liquid level of the water suction tank 1, the cleaning liquid sent from the water suction port 8 to the suction tank 1 tends to foam, so the water suction port 8 is preferably located below the liquid level. It is preferable that the opening be made in the vicinity thereof.

An intake valve is attached to the intake port 4, and the liquid level in the intake tank 1 is adjusted to a constant level by opening and closing the intake valve.

The intake valve consists of a spherical valve body 11 and a float 13 connected to the valve body 11 via a vertical rod 12. When the float 13 floats above a certain level, it pushes up the valve body 11 and opens the valve. When the float 13 is below a certain level, the valve body 11 descends to close the intake port 4.

When the intake port 4 is closed, the air in the suction tank 1 is discharged by the vacuum pump 9, and the cleaning liquid in the container 14 passes through the circulation pipe 3 and the squeezing tool 15 into the suction tank 1.
However, when the intake port 4 is opened, the pressure inside the suction tank 1 becomes atmospheric, and the cleaning liquid inside the suction tank 1 flows down into the container 14 through the check valve 2, causing the liquid inside the suction tank 1 to Reduce surface level.

In the normal operating state, the check valve 2 prevents the cleaning liquid in the container 14 from being sucked into the suction tank 1 through the drain port 6, but prevents the cleaning liquid in the suction tank 1 from flowing down into the container 14. As such, the valve seat has a smaller specific gravity than the cleaning liquid, that is, it is a ball valve that floats on the cleaning liquid, and the valve seat is formed in a tapered shape so that it floats up and closes the valve.

The check valve 2 is preferably connected to the lower end of the drain port 6 so that it opens immediately when the intake valve opens and the pressure in the intake tank 1 approaches atmospheric pressure.

The reflux tube 3 is connected to a connecting table 16 at one end, and the connecting table 16 has a fitting opening 17 opened upward to which the lower end of the milking cylinder 15a is removably and airtightly connected.
An air hole 10 is opened at the bottom of the connecting table 16.

In the embodiment shown in the figure, the lower end of the reflux pipe 3 is communicated with the container 14, but it is also possible to communicate with the drain port 6 via the cheese 18, as shown by the dashed line in the figure.

However, as shown by the solid line in the figure, the one in which the lower end of the circulation pipe 3 is communicated with the container has the advantage that the cleaning liquid can be sucked up more smoothly.

The operation of the milking tool cleaning device configured as described above is as follows: First, the upper end of the milking hose 15b is connected to the water suction port 8, the lower end of the milking cylinder 15a is connected to the fitting opening 17 of the connecting table, and the cleaning liquid is poured into the container 14. The lower end of the drain port 6 and the lower end of the circulation pipe 3 are connected to this, and a vacuum pump 9 connected to the exhaust port 5 is operated.

In this state, since the suction valve is open, the cleaning liquid in the container 14 is sucked up from the drain port 6 into the suction tank.

When the check valve 2 is filled with cleaning liquid, the valve body floats up and is closed, and then the cleaning liquid in the container 14 passes through the milking tool 15 together with the bubbles sucked in from the air hole 10 to the suction tank 1.
sucked inside.

When a certain amount of cleaning liquid is sucked in, the float 13 floats up and opens the intake valve, causing the cleaning liquid in the suction tank 1 to flow down into the container 14 from the exhaust port 6.

As a result, the liquid level in suction tank 1 drops,
The float 13 also descends and closes the intake valve, and the liquid in the container 14 passes from the reflux pipe 3 to the milking tool 15 and returns to the intake tank 1.
The milking tool 15 is sucked into the milking tool 15 by repeating this action
Wash.

The milking tool cleaning device of this invention uses a vacuum pump as the power source to circulate the cleaning fluid as described above, but since the vacuum pump is used for milking, it can also be used for both purposes, making it the most expensive circulating pump. The equipment cost can be significantly lowered as there is no need for the milking hose to be cleaned by the action of the air pump, and the milking hose is cleaned by the air sucked in from the air hole in the circulation pipe, compared to a method that simply circulates only the cleaning fluid. It has a high cleaning effect due to air bubbles, and since the cleaning solution is circulated many times, it can be completely cleaned by running it continuously for a certain period of time.Furthermore, the overall structure and handling are very simple, and the cleaning solution is easy to clean. Since the cleaning fluid does not circulate inside the pump, it is extremely easy to use.Furthermore, even if the amount of washing fluid flowing down from the suction tank and the amount sucked up from the milking tool are not equal, the fluid level in the suction tank is adjusted by the suction valve. It has many features such as keeping the level within a certain range.
