Description

TECHNICAL FIELD

[0001] The utility model belongs to the related technical field of membrane separation equipment, and specifically relates to a membrane separation equipment with ultrasonic cleaning. BACKGROUND

[0002] With the continuous development of industrial technology, membrane separation technology has been widely applied in various fields. The membrane separation equipment has become an important means for liquid separation and purification with the advantages of high efficiency, energy saving, environmental protection and the like. In the membrane separation equipment, a plurality of membrane separation filter cartridges are usually integrated and installed on a support plate to improve the processing capacity and efficiency of the equipment. However, in actual application, we find that after the plurality of membrane separation filter cartridges are integrated and installed on the support plate, there are some problems.

[0003] On the one hand, since the plurality of membrane separation filter cartridges are densely installed on the support plate, there is a lack of effective protection measures in the front-rear direction. During the transportation, installation and use of the equipment, the membrane separation filter cartridges are easily impacted from the front-rear direction. Once impacted, the membrane separation filter cartridges may be deformed, broken or damaged, thereby affecting the normal operation and separation effect of the equipment. On the other hand, the membrane separation filter cartridges are usually made of relatively fragile materials such as ceramics, polymers and the like. These materials are easily damaged when impacted by external force. Moreover, the membrane elements inside the membrane separation filter cartridges are also very delicate and sensitive to external impact. Once the membrane elements are damaged, the separation performance of the equipment will be reduced, and even the equipment cannot work normally.

The equipment should have an effective adjustable protection device to provide reliable anti-collision protection for the membrane separation filter cartridges in the front-rear direction, and ensure the safe operation and separation effect of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-5The membrane separation device with ultrasonic cleaning shown includes a supporting base frame 3 and a right support plate 2 located at the top right end of the supporting base frame 3. A left support plate 7 is located at the top left end of the supporting base frame 3. The supporting base frame 3 provides stable bottom support for the entire device. Multiple circular fixing holes B14 are equidistantly arranged inside the right support plate 2, and multiple circular fixing holes A9 are equidistantly arranged inside the left support plate 7. The multiple circular fixing holes A9 and B14 are symmetrically arranged. Membrane separation filter cartridges 13 are inserted between each of the multiple circular fixing holes A9 and B14. The left and right ends of the multiple membrane separation filter cartridges 13 are exposed at the left left end of the left support plate 7 and the right right end of the right support plate 2, respectively. On the side, rubber protective pads 10 are provided on the inner walls of multiple circular fixing holes A9 and multiple circular fixing holes B14. The rubber protective pads 10 are tightly fitted to the outer wall of the membrane separation filter cartridge 13. The rubber protective pads 10 can fix the filter cartridge and prevent it from shaking during operation. On the other hand, the rubber protective pads 10 have a certain degree of elasticity and can buffer external vibrations and protect the filter cartridge from damage. Multiple support columns 1 are equidistantly arranged at the bottom of the support frame 3. The bottom of each support column 1 is provided with a metal foot pad. The support column 1, the metal foot pad and the support frame 3 are all fixedly connected by welding. The metal foot pad increases the contact area with the ground and can improve the stability of the equipment.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, each of the multiple membrane separation filter cartridges 13 contains a cylindrical hollow fiber membrane core. This core is the key component for membrane separation. The liquid to be separated enters the filter cartridge under pressure. Due to the selective permeability of the membrane, different liquid components create a concentration difference across the membrane, thus achieving separation. Each of the multiple membrane separation filter cartridges 13 has a left end cap 11 sealed to its left side. Each left end cap 11 has a liquid outlet at its center on the left side. Each liquid outlet is sealed with a liquid outlet branch pipe 12. The left ends of the multiple liquid outlet branch pipes 12 are connected to a main liquid outlet pipe 8. The bottom of the main liquid outlet pipe 8 has an external connector. The main liquid outlet pipe 8 connects to the liquid outlets of each membrane separation filter cartridge 13 through the multiple liquid outlet branch pipes 12, collecting and discharging the separated liquid. The external connector at the bottom of the main liquid outlet pipe 8 is used to connect to an external collection system or a next-stage treatment device. Each membrane separation filter cartridge 13 has a right end cap 15 sealed to its right end. Each right end cap 15 has a liquid inlet at its right center. Each liquid inlet is sealed to its outside with a liquid inlet branch pipe 16. The right end of each liquid inlet branch pipe 16 is connected to a main liquid inlet pipe 17. The top of the main liquid inlet pipe 17 is equipped with an external connector. The main liquid inlet pipe 17 is connected to the liquid inlet of each membrane separation filter cartridge 13 through the multiple liquid inlet branch pipes 16, so as to evenly distribute the liquid to be separated into each filter cartridge. The external connector at the top of the main liquid inlet pipe 17 is used to connect to an external liquid supply system. The left end cap 11 and the right end cap 15 are respectively sealed to the left and right ends of the membrane separation filter cartridge 13 to ensure that the liquid will not leak from the ends of the filter cartridge. The liquid outlet on the left end cap 11 is connected to the liquid outlet branch pipe 12 to discharge the separated liquid. The liquid inlet on the right end cap 15 is connected to the liquid inlet branch pipe 16 to introduce the liquid to be separated into the filter cartridge.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, multiple membrane separation filter cartridges 13 are horizontally sealed with sealing flanges 4 on their front outer walls. An ultrasonic generator 6 is sealed and fixed to the front of the sealing flange 4, and a transducer is installed inside the rear of the ultrasonic generator 6. An electrical connector is located at the right end of the ultrasonic generator 6, and the connector is electrically connected to an external control terminal via a wire. The transducer is the core component of the ultrasonic generator 6; it converts electrical energy into ultrasonic energy. When ultrasonic waves propagate in the liquid, they generate cavitation effects and mechanical vibrations, effectively cleaning the membrane surface inside the membrane separation filter cartridge 13, preventing membrane clogging, and improving the membrane's separation performance and service life. During operation, the liquid to be separated enters each inlet branch pipe 16 through the main inlet pipe 17, and then flows into the membrane separation filter cartridge 13 from the inlet. After being separated by the cylindrical hollow fiber membrane core inside the membrane separation filter cartridge 13, the liquid is... The separated liquid flows out from the outlet and is collected in the main outlet pipe 8 through the outlet branch pipe 12 for discharge. At the same time, the ultrasonic generator 6, under the control of the external control terminal, generates ultrasonic waves through the transducer to perform ultrasonic cleaning on the membrane separation filter cartridge 13 to maintain the separation performance of the membrane. During the operation of the equipment, the various components cooperate with each other to achieve the functions of membrane separation and ultrasonic cleaning. The inlet and outlet pipes ensure that the liquid can flow smoothly into and out of the membrane separation filter cartridge 13. The left support plate 7, the right support plate 2, and the rubber protective pad 10 ensure the stable fixation of the filter cartridge. The ultrasonic generator 6 is started periodically or irregularly as needed to perform ultrasonic cleaning on the membrane separation filter cartridge 13 to maintain the separation performance of the membrane. At the same time, the supporting frame 3 and the supporting column 1 provide stable support for the entire equipment to ensure that the equipment will not shake or tilt during operation.

[0027] like Figure 1 , Figure 4 and Figure 5As shown, adjustable protective devices 5 are connected to both the front and rear ends of the left support plate 7 and the right support plate 2. The function of the adjustable protective devices 5 is to provide anti-collision protection for the membrane separation filter cartridge 13, and the position can be adjusted according to actual needs to adapt to different working scenarios. The adjustable protective devices 5 connected to the front ends of the left support plate 7 and the right support plate 2 include a horizontal metal bracket A18, an adjusting slide 19, a horizontal metal bracket B23, and a vertical metal protective rod 25. The horizontal metal bracket A18 is welded to the outer wall of the front end of the supporting base frame 3, and the horizontal metal bracket B23 is connected to the left support plate 7. The top front end outer wall of the support plate 7 and the right support plate 2, as well as the interior of the horizontal metal support A18 and the horizontal metal support B23, are all provided with adjusting grooves 19. Multiple vertical metal guard rods 25 are connected to the two adjusting grooves 19. The multiple vertical metal guard rods 25 can slide left and right in the two adjusting grooves 19. The adjusting grooves 19 provide sliding tracks for the vertical metal guard rods 25, allowing the vertical metal guard rods 25 to be adjusted in the horizontal direction. When they slide to the appropriate position, they can form a protective screen on the front and rear sides of the membrane separation filter cartridge 13. To prevent damage to the filter cartridge from external impacts, the adjustable protective device 5 also includes a bottom anti-detachment block 20 and a top anti-detachment block 24. Each of the multiple vertical metal protective rods 25 has a top anti-detachment block 24 at its top, located at the top of the horizontal metal support B23. Each of the multiple vertical metal protective rods 25 has a bottom anti-detachment block 20 at its bottom, located at the bottom of the horizontal metal support A18. The function of the anti-detachment blocks is to prevent the vertical metal protective rods 25 from sliding out of the adjusting groove 19 during operation. In case of accidental detachment, the stability and reliability of the protective device are ensured. When it is necessary to adjust the position of the vertical metal guard rod 25, the hand-tightened screw 22 is loosened. At this time, the screw rod is no longer pressed against the front outer wall of the horizontal metal bracket A18, and the vertical metal guard rod 25 can slide freely in the adjustment slide 19. After adjusting to the appropriate position, the hand-tightened screw 22 is tightened, and the screw rod is pressed against the front outer wall of the horizontal metal bracket A18. The vertical metal guard rod 25 is fixed in the current position by friction, preventing it from moving during operation.

[0028] like Figure 1 , Figure 4 and Figure 5As shown, the adjustable protective device 5 also includes a fixed stop 21 and a hand-tightening screw 22. Each of the multiple bottom anti-detachment stops 20 has a fixed stop 21 at its front end. All fixed stops 21 are located on the front outer wall of the horizontal metal support A18. A hand-tightening screw 22 is threaded into the upper inner side of the center of each fixed stop 21. After tightening the hand-tightening screw 22, the screw rod can press tightly against the front outer wall of the horizontal metal support A18. During equipment operation, the adjustable protective device 5 can be adjusted according to the actual situation. When it is necessary to install, maintain, or move the membrane separation filter cartridge 13, the vertical metal protective rod 25 can be slid to a position close to the filter cartridge to provide a tighter seal. The adjustable protective device 5 in this ultrasonic cleaning membrane separation equipment provides reliable anti-collision protection for the membrane separation filter cartridge 13 through reasonable structural design and the synergistic effect of various components. It also features convenient operation and strong adaptability. During normal operation, the position of the vertical metal guard rod 25 can be adjusted appropriately according to the working environment and potential external forces to achieve the best protective effect. Meanwhile, the bottom anti-detachment block 20, the top anti-detachment block 24, the fixing block 21, and the hand-tightening screw 22 work together to ensure that the vertical metal guard rod 25 will not accidentally come off during adjustment and can be firmly fixed in the required position.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
