Description

Technical Field

[0001] This utility model relates to the technical field of low-temperature evaporation crystallization equipment, and in particular to a low-temperature evaporation crystallization equipment with a filtration function. Background Technology

[0002] Low-temperature evaporation crystallization equipment is a specialized device that lowers the boiling point of a solution through vacuum depressurization, evaporating the solvent at a lower temperature to achieve supersaturation of the solute and precipitate crystals. Its core design aims to solve problems such as the damage to heat-sensitive substances, high energy consumption, and easy scaling caused by high-temperature evaporation. It is widely used in the separation of high-salt wastewater or high-value substances in chemical, pharmaceutical, and environmental protection industries.

[0003] By installing a feed filter mechanism at the feed inlet of the low-temperature evaporation crystallization equipment, solid impurities (such as particles, fibers, and colloids) in the raw material liquid can be intercepted, preventing them from entering the evaporation crystallization system and causing scaling on the heat exchange surface, blockage of the flow channel, crystal contamination, and equipment corrosion.

[0004] However, the feed filter mechanism in traditional low-temperature evaporation crystallization equipment is often fixed inside the feed pipe by a large number of bolts or other locking structures. This makes it inconvenient to disassemble and clean the feed filter mechanism later, increasing the equipment's downtime for maintenance. Therefore, there is an urgent need for a low-temperature evaporation crystallization equipment that facilitates the disassembly and cleaning of the feed filter mechanism. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-temperature evaporation crystallization device with filtration function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A low-temperature evaporation crystallization device with a filtration function includes a low-temperature evaporation crystallization device body. A lower feed pipe and an upper feed pipe are fixedly installed on the top of the low-temperature evaporation crystallization device body. The upper feed pipe is fixedly installed on the top of the lower feed pipe by a mounting bracket. A mounting seat is rotatably installed between the lower feed pipe and the upper feed pipe through a rotating shaft. A detachable filtration mechanism is installed inside the mounting seat. A locking plate for locking the mounting seat is vertically movable between the lower feed pipe and the upper feed pipe.

[0008] Furthermore, in a preferred configuration, a rotating shaft is installed on one side between the lower feed pipe and the upper feed pipe, and a mounting base is fixedly installed on the rotating shaft.

[0009] In addition, a preferred structure is that a lower positioning ring for supporting the filter mechanism is fixedly provided at the bottom of the mounting base, and an upper positioning ring for pressing the filter mechanism is fixedly provided on the inner wall of the upper feed pipe.

[0010] In addition, in a preferred configuration, positioning elements are fixedly provided on the outer side of the filtering mechanism, and positioning cavities are adapted to be opened on the mounting base for the corresponding positioning elements.

[0011] In addition, in a preferred configuration, a lower locking seat is fixedly installed on the outer side of the lower feed pipe, and an upper locking seat is fixedly installed on the outer side of the upper feed pipe above the lower locking seat. Both the lower and upper locking seats have vertically penetrating silicone pleated cavities.

[0012] In addition, a preferred structure is that multiple guide posts are fixedly provided on the top of the upper locking seat, and a pull plate is fixedly provided on the top of the locking plate, with the pull plate being guided to move by the guide posts.

[0013] The beneficial effects of this utility model are as follows: the raw materials entering the body of the low-temperature evaporation crystallization equipment can be filtered through the filtration mechanism. The filtration mechanism is assembled in the mounting base and locked by the locking plate. This assembly method of the filtration mechanism is simple and quick, and it is convenient for users to disassemble and clean the filtration mechanism in the later stage. Attached Figure Description

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-8 A low-temperature evaporation crystallization device with filtration function includes a low-temperature evaporation crystallization device body 1. A lower feed pipe 11 and an upper feed pipe 12 are fixedly installed on the top of the low-temperature evaporation crystallization device body 1. The upper feed pipe 12 is fixedly installed on the top of the lower feed pipe 11 by a mounting bracket 13. A mounting base 21 is rotatably installed between the lower feed pipe 11 and the upper feed pipe 12 via a rotating shaft 2. A detachable filter mechanism 3 is installed inside the mounting base 21, and a locking plate 41 for locking the mounting base 21 is vertically movable between the lower feed pipe 11 and the upper feed pipe 12.

[0025] A rotating shaft 2 is installed on one side between the lower feed pipe 11 and the upper feed pipe 12, and a mounting base 21 is fixedly installed on the rotating shaft 2. The rotating shaft 2 allows the mounting base 21 to rotate.

[0026] The mounting base 21 has a lower positioning ring 22 fixedly installed at its bottom to support the filter mechanism 3, and an upper positioning ring 123 fixedly installed on the inner wall of the upper feed pipe 12 to press the filter mechanism 3. The specific filter structure and working method of the filter mechanism 3 are existing technologies and are not related to the technical problem of easy disassembly and cleaning of the filter mechanism 3 that needs to be solved in this technical solution, so they will not be described in detail.

[0027] The filter mechanism 3 is fixedly provided with positioning components 31 on its outer side, and the mounting base 21 is provided with positioning cavities 23 corresponding to the positioning components 31. The positioning components 31 and positioning cavities 21 can be adapted to each other for positioning and installation.

[0028] The lower feed pipe 11 is fixedly provided with a lower locking seat 111 on the outside, and the upper feed pipe 12 is fixedly provided with an upper locking seat 121 on the outside above the lower locking seat 111. Both the lower locking seat 111 and the upper locking seat 121 are provided with vertically penetrating silicone pleated cavities 42.

[0029] The upper locking seat 121 has multiple guide posts 122 fixedly installed on its top, and the locking plate 41 has a pull plate 4 fixedly installed on its top. The pull plate 4 is guided to move by the guide posts 122. The guide posts 122 improve the stability of the pull plate 4 and the locking plate 41 during vertical movement, so that the locking plate 41 can be stably locked to the outside of the mounting base 21.

[0030] In this embodiment, the low-temperature evaporation crystallization equipment body 1 lowers the boiling point of the solution (35–50°C) through a vacuum system, heats and concentrates the solution in the evaporation chamber to form a supersaturated solution, and the precipitated crystals are separated into solid products by a solid-liquid separation unit (such as a centrifuge). The mother liquor can be recycled or treated harmlessly, achieving efficient and energy-saving separation and purification. It is worth noting that this is prior art, so it will not be described in detail.

[0031] The lower feed pipe 11 is directly installed on the top of the low-temperature evaporation crystallization equipment body 1, and the upper feed pipe 12 is fixedly installed above the low-temperature evaporation crystallization equipment body 1 via a mounting bracket 13. A mounting base 21 is rotatably provided between the lower feed pipe 11 and the upper feed pipe 12, and the filter mechanism 3 can be assembled inside the mounting base 21. Thus, the filter mechanism 3 can be quickly assembled and disassembled simply by rotating the mounting base 21. It is worth noting that sealing gaskets are provided on both the upper and lower sides of the mounting base 21 to ensure the sealing of the feed pipes.

[0032] Furthermore, when the user needs to disassemble and clean the filter mechanism 3, they only need to pull the locking plate 41 upwards using the pull plate 4, thereby releasing the locking plate 41 from the mounting base 21. Then, the mounting base 21 can be rotated out using the rotating shaft 2, thereby disassembling the filter mechanism 3 for disassembly and cleaning.

[0033] Furthermore, when the user needs to install the filter mechanism 3, they only need to position and install the filter mechanism 3 in the mounting base 21 through the fitting between the positioning member 31 and the positioning cavity 23. Then, the mounting base 21 is rotated between the lower feed pipe 11 and the upper feed pipe 12 via the rotating shaft 2. Finally, the pull plate 4 is pressed down so that the locking plate 41 is simultaneously inserted into the silicone pleated cavity 42 in both the lower feed pipe 11 and the upper feed pipe 12, thereby locking the mounting base 21 through the locking plate 41. At this time, one side of the mounting base 21 is locked by the mounting bracket 13, and the other side is locked by the locking plate 41, thus fixing the mounting base 21.

[0034] When the mounting base 21 is fixed between the lower feed pipe 11 and the upper feed pipe 12, the upper part of the filter mechanism 3 is pressed by the upper positioning ring 123 and the lower part is supported by the lower positioning ring 22, which makes the filter mechanism 3 also positioned.

[0035] Furthermore, the silicone pleated cavity 42 prevents the locking plate 41 from moving automatically, and with the weight of the locking plate 41 itself, the locking plate 41 can be stably locked to the outside of the mounting base 21.

[0036] In this utility model, the raw materials entering the body 1 of the low-temperature evaporation crystallization equipment can be filtered by the filter mechanism 3. The filter mechanism 3 is assembled in the mounting base 21 and locked by the locking plate 41. This assembly method of the filter mechanism 3 is simple and quick, and it is convenient for users to disassemble and clean the filter mechanism 3 in the later stage.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
