Technical Field

The invention belongs to the technical field of separator equipment, and particularly relates to a centrifuge drum sealing and opening operation device.

Background

The disc separator is a precision equipment for separating and purifying liquid-solid and liquid-solid. Sludge formed by the impurities and part of the water separated by the separator is deposited in the area of the piston near the drum cover. When the slag is accumulated to a certain amount, the accumulated slag is discharged in time through the gap between the instantly opened drum piston and the drum cover, and the normal operation of the separator can be achieved by using the device.

Typically, in separator designs, the open service water line and the sealed service water line are two separately operated water paths. The structure not only increases the processing, assembling and sealing water opening operation difficulty of parts, but also is not beneficial to realizing automatic control.

Detailed Description

Referring to fig. 1, the present embodiment provides a centrifuge drum sealing and opening operation device, including a water storage cavity 2, the water storage cavity 2 is connected to a sealed water cavity 8 through a first water inlet 4 and a water inlet channel 5, the water inlet channel 5 is located below a piston 6, a second water inlet 3 is located below the water storage cavity 2, one end of the second water inlet 3 is connected to a water supply device 18, the other end of the second water inlet is connected to an opening cavity 16 through a second water inlet channel 17, a moving slider 13 is arranged on the opening cavity 16, a water drainage channel 10 is formed between the slider 13 and a drum 11, the water drainage channel 10 is connected to a water drainage cavity 12, and the water drainage cavity 12 is provided with a water drainage hole 14.

The top of the piston 6 is hermetically connected with the bottom of the rotary drum cover 1 through a sealing ring 7, and a slag discharge port 9 is arranged between the piston 6 and the rotary drum cover 1.

The opening cavity 16 is provided with a small water drainage hole 15.

The cross section of one side of the drain hole 12 is in a trapezoidal structure.

The operation water passes through the water supply device 18, is sprayed to the water storage cavity 2 after encountering the rotating vertical shaft, and quickly flows to and fills the sealing cavity 8 through the first water inlet hole 4 and the water inlet channel 5. The piston 6 is jacked up instantly under the action of water pressure, the drum cavity is sealed by the sealing ring 7 and the drum cover 1, and the water inlet is stopped immediately when the water operation device is opened for sealing; the separation procedure is started.

When sludge in the drum cavity reaches a specified discharge amount, the sealing and opening operation device starts to feed water into the drum, at the moment, the water storage cavity 2, the water inlet channel 5 below the piston 6 and the sealing cavity 8 are filled with sealing water, the water inlet is filled with the opening cavity 16 after passing through the second water inlet hole 3 and the second water inlet channel 17, and the water in the opening cavity 16 jacks up the slider 13 because the small water drainage hole 15 does not discharge water. A drainage channel 10 is formed between the slide block 13 and the rotary drum body 11. The water in the sealed cavity 8 enters the drainage cavity 12 through the drainage channel 10, and the strong centrifugal force quickly discharges the water in the drainage cavity 12 from the drainage hole 14. At the moment, the water in the sealed cavity is completely discharged, the piston 6 has no supporting force and falls down under the action of gravity, and the sludge in the rotary drum is thrown to a sludge collecting tank (outside) through a slag discharge port 7 by centrifugal force and is discharged. Thus, the sealing and opening operation device completes a complete sealing (running) and opening (deslagging) cycle.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to further illustrate the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, which is intended to be protected by the appended claims. The scope of the invention is defined by the claims and their equivalents.
