Description

Technical Field

[0001] This utility model relates to the field of stearic acid purification technology, specifically a stearic acid purification device. Background Technology

[0002] Stearic acid purification introduction: Key points of vacuum distillation: Equipment selection and installation: A professional vacuum distillation apparatus is required, including a distillation flask, condenser, vacuum pump, receiving flask, etc. It is essential to ensure the apparatus is well-sealed to prevent air leakage from affecting the vacuum effect and distillation process. For example, frosted joints can be used at various connection points, and an appropriate amount of vacuum grease can be applied to enhance the seal. Pressure control: Depending on the properties of stearic acid, the system pressure is generally reduced to a suitable range, typically between a few millimeters of mercury and tens of millimeters of mercury. The pressure can be precisely controlled through the regulating valve of the vacuum pump. Too low a pressure may cause the material to boil violently, while too high a pressure will fail to lower the boiling point and effectively separate impurities.

[0034] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Refer to Figure 1 to Figure 4 This application provides a stearic acid purification device, including a collection box 1.

[0036] A filter assembly 2 is fixedly connected to the top of the collection box 1, and a cleaning assembly 6 is provided on the inner wall of the collection box 1. The filter assembly 2 includes a hollow tube 21 and a sliding tube 22. The hollow tube 21 is fixedly connected to the top of the collection box 1, and the sliding tube 22 is slidably connected to the inner wall of the hollow tube 21. A circular frame 23 is fixedly connected to the top of the sliding tube 22, and a spring 24 is fixedly connected to the bottom of the circular frame 23. The bottom end of the spring 24 is fixedly connected to the collection box 1. A filter box 25 is snapped onto the inner wall of the circular frame 23. A bolt 3 is threadedly connected to one side of the circular frame 23, and the bolt 3 is threadedly connected to the filter box 25.

[0037] The inner wall is provided with a filter screen 26, and a vibration motor 28 is fixedly installed on the top of the circular frame 23. The filter assembly 2 also includes a connecting pipe 27, which is fixedly connected to the bottom end of the filter box 25. The connecting pipe 27 is slidably connected to the collection box 1. A solenoid valve 4 is provided on one side of the collection box 1, and the solenoid valve 4 is connected to the collection box 1 by a thread. Four support legs 5 are fixedly installed at the bottom of the collection box 1, and the four support legs 5 are arranged opposite to each other.

[0038] In this embodiment, stearic acid is first poured into the filter box 25, and then the filter screen 26 filters the stearic acid. The filtered stearic acid enters the collection box 1 through the connecting pipe 27. At the same time, the vibration motor 28 is turned on to drive the circular frame 23 to vibrate. Then the circular frame 23 will vibrate continuously through the spring 24. During the vibration, the circular frame 23 will be drawn into the hollow tube 21 through the sliding tube 22 to achieve a good filtration effect. The filtered residue is outside the collection box 1, which is convenient for cleaning.

[0039] Refer to Figure 1 to Figure 4 In one aspect of this embodiment, the cleaning assembly 6 includes a slide rod 61 and a connecting plate 62. The slide rod 61 is slidably connected to the inner wall of the collection box 1, and the connecting plate 62 is fixedly connected to one end of the slide rod 61. A scraper 63 is fixedly installed on the outer wall of the connecting plate 62. The cleaning assembly 6 also includes a motor 64, which is fixedly installed on the inner wall of the collection box 1. A threaded rod 65 is fixedly connected to the output end of the motor 64. A movable plate 66 is threadedly connected to the side wall of the threaded rod 65. The movable plate 66 is fixedly connected to the slide rod 61. The cleaning assembly 6 also includes a limiting block 67, which is fixedly connected to the side wall of the threaded rod 65.

[0040] In this embodiment, the motor 64 is then turned on, which drives the threaded rod 65 to move. The threaded rod 65 then drives the moving plate 66 to move, so that the moving plate 66 moves through the slide rod 61. Then the slide rod 61 uses the scraper 63 to clean the inside of the collection box 1 through the connecting plate 62, so as to prevent the inside of the collection box 1 from having any residue.

[0041] Working principle: First, stearic acid is poured into the filter box 25. Then, the filter screen 26 filters the stearic acid. The filtered stearic acid enters the collection box 1 through the connecting pipe 27. At the same time, the vibration motor 28 is turned on, which drives the circular frame 23 to vibrate. Then, the circular frame 23 will bounce...

[0042] The spring 24 vibrates continuously, and the circular frame 23 is drawn into the hollow tube 21 through the sliding tube 22 during the vibration process, so as to achieve a good filtration effect. The filtered residue is outside the collection box 1, which is convenient for cleaning.

[0043] Then, starting motor 64 can drive threaded rod 65 to move. Threaded rod 65 will then drive moving plate 66 to move, causing moving plate 66 to move via slide rod 61. Slide rod 61 will then use scraper 63 via connecting plate 62 to clean the inside of collection box 1 to prevent residue from remaining inside collection box 1.
