Description

Technical Field

[0001] This utility model relates to the field of electrodialysis technology, specifically to an electrodialysis plate and frame structure. Background Technology

[0002] Electrodialysis, as an advanced membrane separation technology, plays a vital role in water treatment and material purification. It achieves selective migration of ions in a solution through the action of an electric field, thereby concentrating, desalinating, or separating ions. In practical applications, electrodialysis exhibits high efficiency and energy saving. Compared with traditional processes such as evaporation and crystallization, it can operate under lower temperature and pressure conditions, significantly reducing energy consumption. The equipment has a compact structure and small footprint, making it particularly suitable for areas with limited land resources. This technology has a wide range of applications: in seawater desalination, it can convert seawater into drinking water; in industrial wastewater treatment, it can effectively remove heavy metal ions and salts; and in the food and pharmaceutical industries, it can be used for the separation and purification of substances such as amino acids and antibiotics. The operation process is simple and stable, with a high degree of automation and low maintenance costs.

[0003] Electrodialysis technology is green and environmentally friendly, producing no secondary pollution. It requires no chemical reagents during operation, consuming only electricity and a small amount of electrode water. With continuous improvements in membrane materials and equipment performance, its application prospects will become even broader, playing a greater role in energy conservation, emission reduction, and resource recycling.

[0004] Currently, the plate and frame structure of electrodialysis equipment has significant shortcomings in terms of ease of use. Filter replacement is extremely cumbersome, requiring considerable time and manpower. The complex connection methods and compact spatial layout make disassembly difficult, often requiring maintenance personnel to spend more time than expected to complete the filter replacement. Furthermore, improper operation during disassembly can damage surrounding components, increasing maintenance costs and difficulty. This deficiency severely impacts the efficiency of the equipment, especially in scenarios requiring frequent filter replacements, where the inconvenience is even more pronounced, causing considerable trouble for users. Utility Model Content

[0005] The purpose of this utility model is to provide an electrodialysis plate and frame structure that solves the problem that the filter element is inconvenient to disassemble and replace during use, making it difficult to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrodialysis plate and frame structure, including a mounting frame, a filter element slidably connected inside the mounting frame, a limiting plate slidably connected inside the mounting frame, a locking rod fixedly connected to the side of the limiting plate near the filter element, a threaded rod rotatably connected inside the limiting plate, the threaded rod being threadedly connected to the mounting frame, a retaining ring fixedly connected to the outer side of the threaded rod, a knob fixedly connected to the upper end of the threaded rod, the knob being rotatably connected to the mounting frame, and a limiting mechanism provided on the limiting plate.

[0007] Preferably, the clamping rod is slidably connected to the mounting frame and to the filter element. The design of the clamping rod can limit the position of the filter element.

[0008] Preferably, the retaining ring is rotatably connected to the limiting plate, and the retaining ring contacts the mounting frame. Through the design of the retaining ring, it can limit the threaded rod.

[0009] Preferably, the limiting mechanism includes a push plate, and the limiting plate is slidably connected to the inside of the push plate. A locking block is fixedly connected to the side of the push plate near the knob, and a sliding rod is fixedly connected to the side of the push plate away from the locking block. The sliding rod is slidably connected to the limiting plate, and a spring is provided inside the limiting plate.

[0010] Preferably, the locking block is slidably connected to the limiting plate and the locking block is slidably connected to the knob. Through the design of the limiting mechanism, the filter element can be easily disassembled while maintaining stable installation.

[0011] Preferably, a baffle is fixedly connected inside the limiting plate, and the baffle is slidably connected to the slide rod. Through the design of the baffle, the slide rod can be limited.

[0012] Preferably, one end of the spring contacts the slide rod, and the other end of the spring contacts the limiting plate. Through the design of the spring, the locking block can be driven to limit the knob.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as a threaded rod, a limiting plate, and a locking rod, allows the threaded rod to slide out of the filter element through the limiting plate by rotating the threaded rod, thereby releasing the limiting of the filter element and enabling the filter element to be disassembled and replaced. This solves the problem that the electrodialysis plate and frame structure is inconvenient to disassemble and replace the filter element during use, and is not convenient to use.

[0015] 2. This utility model is equipped with components such as a push plate, a locking block, and a spring. The spring force can drive the push plate to move, causing the push plate to slide the locking block into the knob, thus limiting the knob's position and ensuring that the filter element is easy to disassemble while maintaining stable installation.

[0022] 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.

[0023] Please see Figure 1-5 An electrodialysis plate and frame structure includes an installation frame 1, a filter element 2 slidably connected inside the installation frame 1, a limiting plate 3 slidably connected inside the installation frame 1, a locking rod 31 fixedly connected to the side of the limiting plate 3 near the filter element 2, the locking rod 31 slidably connected to the installation frame 1, and the locking rod 31 slidably connected to the filter element 2. The design of the locking rod 31 can limit the filter element 2. A threaded rod 32 is rotatably connected inside the limiting plate 3, and the threaded rod 32 is threadedly connected to the installation frame 1.

[0024] Please see Figure 2-5 A retaining ring 33 is fixedly connected to the outer side of the threaded rod 32. The retaining ring 33 is rotatably connected to the limiting plate 3. The retaining ring 33 is in contact with the mounting frame 1. Through the design of the retaining ring 33, the threaded rod 32 can be limited. A knob 34 is fixedly connected to the upper end of the threaded rod 32. The knob 34 is rotatably connected to the mounting frame 1. A limiting mechanism 4 is provided on the limiting plate 3.

[0025] Please see Figure 2-5 The limiting mechanism 4 includes a push plate 41, which is slidably connected inside the limiting plate 3. A locking block 42 is fixedly connected to the side of the push plate 41 near the knob 34. The locking block 42 is slidably connected to the limiting plate 3 and the knob 34. Through the design of the limiting mechanism 4, the filter element 2 can be easily disassembled while maintaining stable installation. A sliding rod 43 is fixedly connected to the side of the push plate 41 away from the locking block 42. The sliding rod 43 is slidably connected to the limiting plate 3. A baffle 44 is fixedly connected inside the limiting plate 3. The baffle 44 is slidably connected to the sliding rod 43. Through the design of the baffle 44, the sliding rod 43 can be limited. A spring 45 is provided inside the limiting plate 3. One end of the spring 45 contacts the sliding rod 43, and the other end of the spring 45 contacts the limiting plate 3. Through the design of the spring 45, the locking block 42 can be driven to limit the knob 34.

[0026] The specific implementation process of this utility model is as follows: When in use, by moving the push plate 41 away from the knob 34, the push plate 41 drives the slide rod 43 to slide in the baffle 44, so that the slide rod 43 squeezes the spring 45, and the push plate 41 drives the locking block 42 to slide out of the knob 34, thus releasing the limitation on the knob 34.

[0027] By rotating the knob 34, the threaded rod 32 is rotated, causing the threaded rod 32 to move in the mounting frame 1. This causes the threaded rod 32 to move within the mounting frame 1, which in turn causes the limiting plate 3 to move. The limiting plate 3 then causes the locking rod 31 to move, allowing the locking rod 31 to slide out of the filter element 2. This releases the limiting effect on the filter element 2, allowing it to be disassembled and replaced.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
