Description

Technical Field

[0001] The utility model relates to the technical field of tubular membrane material processing and detection, in particular to a leakage point detection device for tubular membrane materials. Background Art

[0002] Tubular membrane materials play an important role in the industrial and medical fields, including cellulose casings, collagen casings, plastic casings, cellulose dialysis bags, etc. The use of these tubular membrane materials involves the transportation, filtration and isolation of liquids, gases or solids, so their sealing performance is particularly important. However, even high-quality tubular membrane materials may have leaks or water leakage problems, which may cause adverse effects. The leak detection device is a device specially used to monitor whether there are leaks or water leakages in tubular membrane materials. Its function is to promptly detect and alarm the leak location so as to promptly repair or replace the affected parts. During operation, the tubular membrane material shrink rod is put on the water injection pipe, and the tubular membrane material shrink rod is put on the water injection pipe. One end of the rod is tied (fixed) to the water injection pipe, and the water pipe valve is opened to release the tubular membrane material while injecting water. When the water is full, the other end is also tied to control the water pressure to simulate the use pressure requirement. After the water pressure is constant, the whole tubular membrane material (casings are most commonly used) is manually picked up to check whether there are any leaks. If there are small pinholes or other leaks, it is unqualified, and if there are no leaks, it is qualified. However, it usually takes several minutes to operate and detect a tubular membrane material, that is, the water needs to fill the entire tubular membrane material, and it is always in operation. This leads to low efficiency in dew point detection of tubular membrane materials by staff. In addition, different inspectors have different techniques, different water injection speeds, and different water pressures in the process, which can easily cause explosions due to personnel reasons and failure of dew point detection.

[0019] The tubular membrane set rod 8 is composed of a long tube and a water injection core tube. The long tube is fixed to the top of the drain pan 2. The water injection core tube is threadedly installed on the top opening of the long tube. The tubular membrane set rod 8 is composed of two sections of long tubes and water injection core tubes that can be threadedly connected. The top of the water injection core tube can be processed into different diameters, but it is consistent with the connection with the long tube, so that it can be replaced at any time according to the tubular membrane materials of different diameters. The tubular membrane clamp 9 is installed on the long tube. The tubular membrane clamp 9 can just separate the casing of the water-injected part and the casing of the non-water-injected part, and as the casing moves upward, it will not leak or be clamped too tightly and cannot move;

[0020] The waste tubular film winding device 7 comprises a film rolling roller 704 and a material guide roller 705 which are rotatably mounted at both ends of the inner side box 6. A C-mouth protective cover 701 is fixed to one end of the back of the upper shell 3. A servo motor 702 is mounted on one side of the back of the C-mouth protective cover 701. A pulley transmission structure 703 for driving the film rolling roller 704 to rotate is mounted on the output end of the servo motor 702. When the end of the waste casing is wound around the film rolling roller 704, power is transmitted to the film rolling roller 704 through the servo motor 702 and the pulley transmission structure 703, so that the waste casing or the casing to be tested is wound up.

[0021] The film material extrusion structure 12 includes a stainless steel fixed roller 1201 and a rubber extrusion roller 1202 rotatably mounted on the inner wall of one side of the upper shell 3. One end of the rubber extrusion roller 1202 is connected to the output end of the servo motor 702 through a coupling. The rotary power of the servo motor 702 is synchronously transmitted to the rubber extrusion roller 1202. At this time, the rubber extrusion roller 1202 and the stainless steel fixed roller 1201 squeeze out the water in the water-injected casing.

[0022] The water droplet sensing assembly 10 includes an outer support tube 1001 fixed at the center position inside the partition plate 5, and a water droplet sensor 1002 installed on the inner wall of the outer support tube 1001. The outer support tube 1001 can be set to be about 30 to 60 centimeters long, and the inner wall of the outer support tube 1001 is 15 to 30 centimeters across the casing. When there is a leak in the water-injected casing in the outer support tube 1001, the water column splashes onto the water droplet sensor 1002, and the water droplet sensor 1002 sends the detected electrical signal to the control panel 4, and the control panel 4 controls the sound and light alarm 11 to alarm, thereby achieving the purpose of alarm prompting;

[0023] The water injection control structure 13 includes a right-angle liquid inlet pipe 1301 installed inside the lower return water tank 1, and a switch valve 1303 installed on the top of the right-angle liquid inlet pipe 1301. The other end of the right-angle liquid inlet pipe 1301 is interconnected with the bottom end of the tube membrane set rod 8. A pressure gauge 1302 is installed on one side of the surface of the right-angle liquid inlet pipe 1301. The switch valve 1303 is connected to the external water supply end. At this time, water enters the tube membrane set rod 8 through the switch valve 1303 and the right-angle liquid inlet pipe 1301, and is injected into the casing through the tube membrane set rod 8. During this process, the pressure gauge 1302 detects the liquid pressure. The pressure gauge 1302 and the switch valve 1303 ensure that the water injection speed and water pressure of each tubular membrane material are consistent. Compared with manual water injection, it can ensure that each tubular membrane material is filled with water in the same way, making the detection conditions more consistent, improving the accuracy of detection, and reducing the false alarm rate of leak detection.

[0024] When the embodiment of the present application is in use, first, the staff will completely cover the tubular membrane material to be tested on the tubular membrane cover rod 8 in a stacked form. The tubular membrane material can be a cellulose casing, a collagen casing, a plastic casing, a cellulose dialysis bag, etc., and one end of the casing is knotted and sealed, and the knotted end of the casing is passed through the water drop sensing component 10 and the membrane material extrusion structure 12 and introduced into the tubular membrane waste winding device 7 in the side box 6, and the casing end covered on the tubular membrane cover rod 8 is fixed by the tubular membrane clamp 9, and then the water injection control structure 13 is connected to the external water supply end, so that the external water supply end supplies water to the water injection control structure 13 and the tubular membrane cover rod 8. In this process, the water flow rate and pressure can be controlled by the water injection control structure 13 to ensure that the casing expands, and then the staff turns on the tubular membrane waste winding device 7 through the control panel 4 to work. At this time, the water-injected casing goes upward into the water drop sensing component 10, When the casing moves upward, the water column is always in the sensing area of ​​the water droplet sensing component 10. If the casing has a leak such as a pinhole, a small water column or water droplet will be squeezed out and reach the sensing area. At this time, the sound and light alarm 11 will sound an alarm, proving that the sampled product has a leak. The tubular film waste material winding device 7 continues to wind up the waste casing. During this process, the film material extrusion structure 12 discharges the liquid in the casing to achieve the effect that the casing passes but the water does not. The liquid flows down and is collected by the lower return water tank 1 through the drain tray 2. The head of the next casing can be connected to the tail of the previous one and connected by buckles or the like, so as to realize the continuous leakage detection function of the casing. The use of this device can improve the accuracy of leakage detection of tubular membrane materials, improve the detection speed and efficiency, and the lower return water tank 1 actively collects water during this process to achieve the purpose of saving water for detection, and the timely alarm prompt of the sound and light alarm 11 saves a lot of labor costs of detection personnel and tubular membrane material costs.
