The present invention relates to a pure water supply device for cleaning the neck portion of the color brown tube, and more particularly, to an automatic supply device of pure water used to clean and clean the inner surface of the neck where the electron gun is located and sealed in the manufacturing process of the color brown tube. will be.

In general, the neck portion of the color-brown tube is a portion where the electron gun is installed, and if there is any foreign matter on the inner surface of the neck, the internal pressure may be poor, so the neck portion is washed with pure water to remove the foreign substance before the electron gun is installed.

However, in the related art, pure water is not supplied in a certain amount without the automatic supply device of pure water supplied to the neck portion, and since the pure water is not automatically supplied, there were many difficulties in the washing operation.

The present invention has been devised to solve the above problems, by providing a pure automatic feeder that can be automatically supplied a certain amount of pure water for washing the neck to reduce the consumption of pure water, and to facilitate the cleaning operation There is a purpose.

An object of the present invention as described above is a pure storage tank for storing pure water, a pure supplement means for replenishing the pure water according to the water level of the pure storage tank, and receiving pure water from the pure storage tank by gravity to supply pure water to the neck. This is achieved by providing a casting machine for electrically controlling the pure feeding means and the pure automatic feeding device.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The figure is a schematic diagram of a pure automatic feeding device.

Pure water storage tank 10 for storing the pure water in a predetermined position from the ground is installed by the support 11, the inside of the pure water storage tank 10 is a cylinder that moves up and down by buoyancy according to the level of pure water ( 20 is embedded, and a sensing plate 21 is formed at the tip of the cylinder 10. In addition, a drain valve 12 is installed at one side of the bottom surface of the pure water storage tank 10 to drain the pure water.

In addition, a replenishment line 22 is formed on the upper side of the pure water storage tank 10 to supplement the pure water, and a sensor to detect the vertical operation of the sensing plate 21 on the upper portion of the pure water storage tank 10. (23) and (24) are installed up and down, and the replenishment line 22 is a solenoid for opening and closing the replenishment of pure water in accordance with the signals of the main valve 25 and the sensors 23 and 24 for opening and closing the replenishment of the pure water. The valve A 26 is provided. In addition, a supply line 30 for supplying pure water is formed on the lower side of the pure storage tank 10.

In addition, a needle valve 31 is installed in the supply line 30 to adjust the amount of pure water supplied, and a solenoid valve B 32 for opening and closing the supply of pure water is installed at the tip of the supply line 30.

In addition, a nozzle 34 for spraying pure water is connected to a hose 36 at an end of the supply line 30, and a nozzle feeder 33 is installed at a lower end of the nozzle 34, and the nozzle transfer is performed. The base 33 is attached to the cylinder 35 which is operated up and down.

In addition, a casting working plate 40 for controlling the pure automatic feeding device in response to the signal of the sensor is installed on one side of the device.

According to the present invention configured as described above, when the neck 100 is to be cleaned, the cylinder 35 is raised so that the nozzle 34 enters the neck 100, and receives the signal to the solenoid valve B 32. Is opened and the pure water stored in the pure water storage tank 10 is supplied by a predetermined amount of gravity to wash the neck 100.

In addition, when the water level of the pure water in the pure water storage tank 10 is lowered after the pure water is supplied, the cylinder 20 is lowered accordingly, and the sensing plate 21 formed at the tip of the cylinder 20 is the sensor 24. Upon receiving this signal, solenoid valve A (26) is opened and pure water is replenished into the pure water storage tank (10). In addition, pure water is continuously replenished and the cylinder 20 rises due to buoyancy so that when the sensing plate 21 comes to the position of the sensor 23, the solenoid valve A 26 is closed by receiving this signal.

In addition, when washing the neck 100, the main valve 25 is always open, and the amount of pure water supplied to the supply line 30 can be adjusted by the needle valve 31.

As described above, according to the present invention, since a certain amount of pure water for washing the neck can be automatically supplied, the consumption of unnecessary pure water can be reduced, and a suitable worker can facilitate the washing operation.
