Technical Field

[0001] This utility model relates to the field of tubular membrane equipment technology, specifically a tubular membrane equipment for evaporators. Background Technology

[0002] In modern industrial production, evaporators, as crucial equipment for solution concentration and separation, are widely used in various fields such as chemical, pharmaceutical, and food industries. Tubular membrane equipment, as a core component of evaporators, undertakes key functions such as filtration and separation. Its performance directly affects the evaporator's efficiency and product quality. Existing tubular membrane equipment specifically designed for evaporators typically incorporates a pre-filter structure to improve filtration quality. However, after prolonged use, this pre-filter is prone to clogging due to impurity accumulation. Because its structure is fixed within pipes, the limited space makes cleaning and maintenance cumbersome, time-consuming, and reduces production efficiency. To address these issues, the inventors have proposed a tubular membrane device specifically designed for evaporators to solve these problems. Utility Model Content

[0018] 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.

[0019] Example: Figure 1-4 As shown, this utility model provides a technical solution: a tubular membrane device specifically for evaporators, including an outer shell tube 1, a primary filter plate 11 movably installed on the inner side of one end of the outer shell tube 1, a tubular membrane body 12 fixedly installed inside the outer shell tube 1, an array of grooves 13 distributed on the inner side of one end of the outer shell tube 1, sliders 14 slidably engaged on the inner side of each groove 13, one end of each slider 14 fixedly connected to the primary filter plate 11, fixing studs 15 fixedly installed inside each groove 13, and one end of each slider 14 slidably sleeved on the outer side of each fixing stud 15. One end of each slide is threaded with a hexagonal nut 16, and one end of the hexagonal nut 16 is in movable contact with the slider 14. A thrust spring 17 is fixedly installed on the inner side of each slide groove 13, and one end of the thrust spring 17 is in movable contact with the slider 14. An array of fixing blocks 18 is fixedly installed on the outer side of the outer casing tube 1. A T-shaped rod 19 is slidably installed on the inner side of each fixing block 18, and one end of the T-shaped rod 19 is slidably engaged with the inner side of the slider 14. A symmetrically distributed tension spring 20 is fixedly installed on one end of each T-shaped rod 19, and one end of the tension spring 20 is fixedly connected to one end of the fixing block 18.

[0020] The outer side of the outer casing tube 1 is fixedly fitted with uniformly distributed protective rings 21. Each protective ring 21 has an array of circular holes 22 on its outer side. Each circular hole 22 has a damper 23 fixedly installed on its inner side. Each damper 23 has a protective plate 25 fixedly connected to one end. Each damper 23 has an anti-vibration spring 24 fixedly connected to its outer side. One end of the anti-vibration spring 24 is fixedly connected to the protective plate 25.

[0021] By adopting the above technical solution, the outer shell tube 1 is protected by setting a protective ring 21 in conjunction with a protective plate 25, and the impact resistance of the protective plate 25 is enhanced by the action of the damper 23 and the anti-vibration spring 24, thereby effectively protecting the outer shell tube 1 and thus effectively protecting the tubular membrane body 12 inside the outer shell tube 1, improving safety.

[0022] Each T-shaped rod 19 is fixedly fitted with a security ring 26, one end of which is attached to the outer surface of the outer casing tube 1.

[0023] By adopting the above technical solution, the sealing effect is strengthened by setting the encryption ring 26 to be attached to the outer shell tube 1.

[0024] The T-shaped rod 19 is slidably connected to symmetrically distributed guide rods 27, one end of which is fixedly connected to the corresponding fixing block 18.

[0025] By adopting the above technical solution, the guide rod 27 is set to help the T-shaped rod 19 to maintain stability during movement.

[0026] Limit rings 28 are fixedly connected to the end of the guide rod 27 away from the fixed block 18.

[0027] By adopting the above technical solution, the movement of the T-shaped rod 19 is limited by setting the limit ring 28.

[0028] A tie rod 29 is fixedly installed at the middle position of the top of each T-shaped rod 19.

[0029] By adopting the above technical solution, the T-shaped rod 19 can be easily pulled out of the slider 14 by using the pull rod 29.

[0030] Working principle: First, when the outer casing tube 1 is put into use in the evaporator, the tubular membrane body 12 processes the liquid. The liquid first passes through the preliminary filter medium of the primary filter plate 11 before entering the tubular membrane body 12. However, when the primary filter plate 11 becomes clogged after long-term use, the hexagonal nut 16 is removed from the fixing stud 15, and then the T-shaped rod 19 is pulled to move. When the T-shaped rod 19 disengages from the slider 14, the slider 14 is pushed to move by the thrust spring 17. The slider 14 then drives the primary filter plate 11 to pop out of the outer casing tube 1 for cleaning. After cleaning, the primary filter plate 11 is pushed back into the outer casing tube 1 and the slider 14 slides in. The slide groove 13 is fitted onto the fixing stud 15. The tension spring 20 pulls the T-shaped rod 19 down and inserts it into the slider 14 for positioning. Then, the hexagonal nut 16 is installed for fixation, thereby realizing the quick assembly and disassembly of the primary filter plate 11. This facilitates the cleaning and maintenance of the primary filter plate 11. The structure is ingenious, convenient and practical. The protective ring 21 works in conjunction with the protective plate 25 to protect the outer shell tube 1. The damper 23 and the shock-absorbing spring 24 enhance the impact resistance of the protective plate 25, thereby effectively protecting the outer shell tube 1 and the tubular membrane body 12 inside the outer shell tube 1, improving safety.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
