Description

Technical Field

[0001] This utility model relates to the field of sodium acetate crystallization technology, specifically to a sodium acetate crystallization device with a separation and filtration mechanism. Background Technology

[0002] Sodium acetate, as an important organic chemical raw material, has wide applications in printing and dyeing, pharmaceuticals, wastewater treatment, and many other fields. The quality and production efficiency of its crystalline products directly affect the development of these industries. In the sodium acetate production process, the crystallization device is the key equipment for separating sodium acetate from the solution and crystallizing it, and the separation and filtration mechanism within it plays a decisive role in the purity and yield of the final product.

[0003] Existing crystallization devices use plate and frame filter presses for filtration and separation. After long-term operation, the filter cloth of the plate and frame filter press is prone to clogging, which leads to a significant decrease in filtration efficiency and requires frequent replacement of the filter cloth, increasing production costs and downtime for maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a sodium acetate crystallization device with a separation and filtration mechanism. The solution in the crystallization tank is drawn into the filter frame by a circulation component. The sodium acetate crystals are separated by the high-speed rotation of the filter frame, which achieves rapid separation and has a simple structure.

[0005] To address the problems of existing technologies, this utility model provides a sodium acetate crystallization device with a separation and filtration mechanism, comprising a main body, the main body including a lifting body capable of vertical movement; a crystallization tank for crystallizing sodium acetate, the bottom of which is connected to a valve; a filter assembly disposed on the main body near the crystallization tank and directly above it, the filter assembly including a support frame and a rotating shaft mounted at the center of the support frame, the filter assembly also including a multi-layered filter frame disposed on the support frame; a drive assembly disposed on the lifting body for driving the filter assembly to rotate; and a circulation assembly disposed outside the main body for drawing the solution from the crystallization tank into the filter frame.

[0006] Preferably, the diameter of the filter pores in the filter frame gradually decreases from the inside to the outside.

[0007] Preferably, the filter assembly further includes a support block disposed on a support frame, the support block having a limiting groove, and the outside of the filter frame also having a limiting block that can cooperate with the limiting groove.

[0008] Preferably, the filter assembly further includes a pressing block capable of pressing the filter frame onto the support block, and a screw is rotatably disposed on the pressing block, the screw engaging with the support frame via threads.

[0009] Preferably, the drive assembly includes a driven pulley connected to the rotating shaft, and the drive assembly also includes a rotary drive component fixed to one end of the elevator body away from the main body. The output end of the rotary drive component is connected to a drive pulley, and the drive pulley and the driven pulley are connected by a belt.

[0010] Preferably, the filter assembly is provided with a protective cover, and the protective cover is provided with a quick-release mechanism, which connects the protective cover to the bottom of the lifting body.

[0011] Preferably, the circulation assembly includes a circulation pump disposed outside the crystallization tank, the inlet end of the circulation pump is connected to a feed pipe that can be connected to a valve, the outlet end of the circulation pump is connected to a discharge pipe, the rotating shaft is hollow inside, and the discharge pipe extends from the top of the rotating shaft to the filter frame.

[0012] Preferably, the main body includes a base, and a sleeve is provided on the top of the base. The sleeve is slidably engaged with the lifting body. The sleeve is also provided with a hydraulic mechanism for driving the lifting body to move up and down. The outside of the sleeve is also provided with a protective component for limiting the crystallization tank.

[0013] The advantages of this utility model compared to the prior art are:

[0014] 1. This application integrates a circulation component and a filtration component to form a highly efficient and reliable rapid separation system for sodium acetate crystals. Compared with traditional filtration devices, this device achieves significant improvements in both processing efficiency and filtration effect. During operation, the circulation pump, acting as a power source, continuously and stably extracts the solution containing sodium acetate crystals from the crystallization tank and delivers it to the filter frame in the filtration component. The filter frame adopts a unique multi-layer structure design, allowing the solution to be more thoroughly filtered as it passes through. Simultaneously, the filter frame is tightly connected to the support frame and can rotate at high speed with the support frame. This dynamic filtration method effectively breaks through the limitations of traditional static filtration, further improving filtration efficiency and effect through the synergistic effect of centrifugal force and filtration, ensuring rapid and thorough separation of sodium acetate crystals from the solution.

[0015] 2. This application features a limiting block on the outside of the filter frame that matches the upper limit groove of the support block. This design ensures stable installation of the filter frame. Simultaneously, by rotating the screw, the pressure block can be driven to descend, ultimately pressing the filter frame tightly onto the support block. This pressing method not only enhances the connection strength between the filter frame and the support block but also effectively prevents loosening or detachment that may occur due to high-speed rotation.

Detailed Implementation

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-6As shown, this utility model provides a sodium acetate crystallization device with a separation and filtration mechanism, including a main body 1, which includes a lifting body 14 capable of vertical movement; a crystallization tank 2 for crystallizing sodium acetate, with a valve 21 connected to the bottom of the crystallization tank 2; a filter assembly 5, which is located on the main body 1 near the crystallization tank 2 and directly above the crystallization tank 2, the filter assembly 5 including a support frame 51 and a rotating shaft 511 installed at the center of the support frame 51, and the filter assembly 5 also including a filter frame 52 mounted on the support frame 51, the filter frame 52 having a multi-layer structure. A drive assembly 6 is mounted on the lifting body 14 for driving the filter assembly 5 to rotate. A circulation assembly 3 is also provided outside the main body 1 for drawing the solution in the crystallization tank 2 into the filter frame 52. The diameter of the filter holes in the filter frame 52 gradually decreases from the inside to the outside.

[0025] Sodium acetate solution is poured into crystallization tank 2, where crystallization occurs, causing sodium acetate to precipitate from the solution. Generally, the solution is first heated to form a saturated solution, then cooled. Crystals precipitate from the saturated solution, and the solution is drawn into filter frame 52. Due to the multi-layered structure of filter frame 52 and the gradually decreasing pore diameter from the inside to the outside, impurities in the mixture are intercepted layer by layer on filter frame 52, while the sodium acetate crystals pass through filter frame 52, achieving separation of the crystallized product from the impurities. During the rotation of filter assembly 5, the centrifugal force generated by the rotation helps to accelerate the filtration process and improve filtration efficiency.

[0026] The filter assembly 5 also includes a support block 512 disposed on the support frame 51, the support block 512 having a limiting groove 5121, and the filter frame 52 having a limiting block 521 on its exterior that can cooperate with the limiting groove 5121. The filter assembly 5 also includes a pressing block 53 that can press the filter frame 52 onto the support block 512, and a screw 531 is rotatably disposed on the pressing block 53, the screw 531 engaging with the support frame 51 via threads.

[0027] The filter frame 52 is placed on the support block 512 of the support frame 51, so that the limiting block 521 on the outside of the filter frame 52 is accurately engaged in the limiting groove 5121 on the support block 512, thus achieving the initial positioning of the filter frame 52. The screw 531 on the rotating pressure block 53 is then rotated. Since the screw 531 is threadedly engaged with the support frame 51, the pressure block 53 gradually moves downward as the screw 531 rotates, eventually pressing the filter frame 52 tightly onto the support block 512, thus fixing the filter frame 52 and ensuring that the filter frame 52 will not shift or loosen during subsequent filtration processes.

[0028] The drive assembly 6 includes a driven pulley 63 connected to the rotating shaft 511. The drive assembly 6 also includes a rotary drive 61 fixed to one end of the elevator body 14 away from the main body 1. The output end of the rotary drive 61 is connected to a drive pulley 62. The drive pulley 62 and the driven pulley 63 are connected by a belt.

[0029] The rotary drive unit 61 is activated, causing it to rotate and drive the drive pulley 62 connected to its output end to rotate as well. The drive pulley 62 transmits rotational power to the driven pulley 63 via a belt, causing the driven pulley 63 to rotate under the influence of the power. Since the driven pulley 63 is connected to the rotating shaft 511, its rotation drives the rotating shaft 511 to rotate as well, thus causing the entire filter assembly 5 to rotate. Due to the multi-layer structure of the filter frame 52 and the gradually decreasing diameter of the filter holes from the inside to the outside, impurities in the mixture are intercepted layer by layer on the filter frame 52, while sodium acetate crystals pass through the filter frame 52, achieving separation of the crystallization product from the impurities. At the same time, the centrifugal force generated by the rotation of the filter assembly 5 helps to accelerate the filtration process and improve filtration efficiency.

[0030] The filter assembly 5 is externally fitted with a protective cover 4, which is equipped with a quick-release mechanism 41. The protective cover 4 is connected to the bottom of the lifting body 14 via the quick-release mechanism 41. The protective cover 4 primarily prevents liquid from splashing out, and the quick-release mechanism 41 is used to quickly connect and disconnect the protective cover 4 from the bottom of the lifting body 14. The quick-release mechanism 41 is a latch. When it is necessary to inspect, maintain, or replace the filter assembly 5, the protective cover 4 can be easily and quickly removed from the lifting body 14 via the quick-release mechanism 41, without the need for complicated tools or cumbersome operations, greatly improving work efficiency.

[0031] The circulation assembly 3 includes a circulation pump 31 located outside the crystallization tank 2. The inlet end of the circulation pump 31 is connected to an inlet pipe 311 that can be connected to a valve 21, and the outlet end of the circulation pump 31 is connected to an outlet pipe 312. The rotating shaft 511 is hollow inside, and the outlet pipe 312 extends from the top of the rotating shaft 511 into the filter frame 52. The main body 1 includes a base 11, and a sleeve 12 is provided on the top of the base 11. The sleeve 12 is slidably engaged with the lifting body 14. A hydraulic mechanism for driving the lifting body 14 to move up and down is also provided in the sleeve 12. The hydraulic mechanism can be a hydraulic cylinder. A protective component 13 for limiting the movement of the crystallization tank 2 is also provided on the outside of the sleeve 12. The valve 21 at the bottom of the crystallization tank 2 is opened, and the circulation pump 31 is started. The circulation pump 31 draws the solution from the crystallization tank 2 through the inlet pipe 311, and then delivers the solution to the filter frame 52 through the outlet pipe 312.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
