Detailed ways

As shown in Figure 1-3, a self-cleaning ceramic membrane, the tubular membrane core 2 is installed in the membrane shell 1, and there are multiple sets, which can improve the working efficiency of the ceramic membrane, and the two ends of the membrane shell 1 are respectively installed The top cover 4 and the bottom cover 7, wherein the inside of the top cover 4 is provided with a cavity, the top of the cavity is connected to the liquid inlet pipe 3, and the bottom of the cavity is provided with a number of liquid outlets, which communicate with the top of the plunger 13 , and the plunger 13 is fixedly connected with the top cover 4. The cavity provided in the top cover 4 allows the liquid to enter the cavity through the liquid inlet pipe 3, and then enters each tubular membrane core through the self-cleaning plug 8 2, so that each tubular membrane core 2 can be effectively utilized.

Specifically, the top cover 4 and the bottom cover 7 are connected by a connecting rod 6, and the connecting rod can be a screw, one end of which passes through the bottom cover to be provided with a first through hole, and the other end passes through the second through hole on the top cover 4, and is screwed on. Nut, as the nut is tightened, the top cover 4 and the bottom cover 7 are close to each other, and are tightly pressed against the two ends of the membrane shell 1 to realize sealing. At this time, the plunger 13 of the self-cleaning plug 8 is also inserted into the tubular membrane core 2 The liquid inlet end, and since the self-cleaning plug 8 is also provided with a collar, the plunger 13 will not fully extend into the tubular membrane core 2 .

Further, the self-cleaning plug 8 includes a plunger 13 and a collar. One end of the plunger 13 is inserted into the liquid inlet end of the tubular membrane core 2. Several high-pressure flushing tanks 14 are embedded on the outer peripheral side of the plunger 13. When the column When the plug 13 is inserted into the tubular membrane core 2, the high-pressure flushing tank 14 is attached to the inner wall of the tubular membrane core 2 to form a through hole with openings at both ends. Since the plug wall of the plunger 13 is provided with a cavity, the The top of the hole communicates with the cavity, and the cavity on several plungers 13 communicates with the high-pressure water pipe 10 through the communication pipe 12, so that the external water source flows into the cavity through the high-pressure water pipe 10, and enters the through hole through the cavity Finally, the high-pressure water source flows down the inner wall of the tubular membrane core 2 to clean the inner wall of the tubular membrane core 2. In addition, the tail of the high-pressure flushing tank 14 is in an open shape, which realizes the purpose of flushing the inner wall of the tubular membrane core 2 in a large area, and avoids the small cleaning area of the through holes in the straight path.

Furthermore, the slag discharge end of the tubular membrane core 2 is connected to the slag discharge pipe 9. When the ceramic membrane works normally, the high pressure water pipe 10 is in a normally closed state through the control valve 11, and the slag discharge pipe 9 at this time is used to discharge the pipe When the ceramic membrane is self-cleaning, the slag discharge pipe 9 is used to discharge the residue after flushing and a part of the liquid that has not entered the drain pipe 5.

There is a gap between the tubular membrane core 2 and the membrane shell 1, and the gap is connected to the liquid discharge pipe 5. During use, the separated solid impurities are discharged from the slag discharge pipe 9, and the liquid enters the gap through the outer wall of the tubular membrane core 2. Drain pipe 5 discharges. The number of tubular membrane cores 2 is the same as the number of self-cleaning plugs 8, and the self-cleaning plugs 8 are connected to each other through the connecting pipe 12, so that the high-pressure clean water of the high-pressure water pipe 10 can enter the interior of each self-cleaning plug 8, and the high-pressure water pipe 10 external water supply system.

The working process of the device will be described in detail below in conjunction with the drawings in the embodiments.

The high-pressure water pipe 10 is connected to the external water supply system. The external water source enters the high-pressure water pipe 10 through the opening of the control valve 11, and flows into the cavity of each plunger 13 through the communication pipe 12, and then enters the high-pressure flushing tank 14. Due to the high-pressure flushing The notch of the groove 14 fits the inner wall of the tubular membrane core 2 to form a through hole, so the high-pressure water source enters the through hole and flows down the inner wall of the tubular membrane core 2, thereby realizing the purpose of flushing the inner wall of the tubular membrane core 2. And because the tail of the high-pressure flushing tank 14 is in an open shape, the inner wall of the tubular membrane core 2 can be flushed on a large scale;

In addition, if you want to further clean the ceramic membrane, you can install a motor at the bottom of the tubular membrane core 2, and the output end of the motor can be connected to several tubular membrane cores 2 through a chain, so that when the motor rotates, it can drive the tubular membrane core 2 to rotate. At this time, the plunger 13 does not move, and even if only one high-pressure flushing tank 14 is provided, the entire tubular membrane core 2 can be cleaned.

The above are only preferred embodiments of the utility model creation, and are not intended to limit the utility model creation. Any modifications, equivalent replacements and improvements made within the spirit and principles of the utility model creation should be included in the Within the scope of protection created by the utility model.
