Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1 to 8The present invention discloses a cryogenic crystallization apparatus for preparing diesel anti-wear agents from mixed oleic acid. It includes a chassis 1, a filter housing 2 fixedly connected to the chassis 1, a sliding groove on the filter housing 2, a controller 3 mounted externally to the filter housing 2, a cryogenic crystallization chamber 4 fixedly connected to the top of the filter housing 2, a feed pipe fixedly connected to the cryogenic crystallization chamber 4, a crystallization chamber 5 connected inside the cryogenic crystallization chamber 4, a first fixing frame 6 fixedly connected externally to the cryogenic crystallization chamber 4, and a first drive motor 7 fixedly mounted on the first fixing frame 6. A stirrer 8 is rotatably connected to the crystallizer 4. The stirrer 8 is connected to the output shaft of the first drive motor 7. The stirrer 8 is used to stir the frozen crystallization oil. A liquid level sensor 9 and a temperature sensor 10 are installed inside the frozen crystallizer 4. A freezing compressor 11 is installed inside the frozen crystallizer 4. The freezing compressor 11 freezes and crystallizes the mixed oleic acid. A feed pipe 12 connects the filter box 2 and the frozen crystallizer 4. A first electric valve 13 is installed on the feed pipe 12. A sliding connection is made on the filter box 2. A filter box 14 is connected to the base 1, which is used to filter impurities in the cryogenic crystallization oil. Multiple discharge buttons 15 are installed on the filter box 14. Multiple discharge pipes 16 are fixedly connected to the filter box 2, and a second electric valve 17 is installed on each discharge pipe 16. Multiple mounting plates 18 are fixedly connected to the base 1, and weight sensors 19 are installed on each mounting plate 18. A gantry conveyor 20 connects the base 1 and the cryogenic crystallization chamber 4. The gantry conveyor 20 has a chute and a second fixed frame is fixedly connected to it. 21. A second drive motor 22 is fixedly installed on the second fixed frame 21. A lead screw 23 is rotatably connected to the gantry conveyor frame 20. The lead screw 23 is connected to the output shaft of the second drive motor 22 through a coupling. A sliding block 24 is slidably connected to the gantry conveyor frame 20. The sliding block 24 is threadedly connected to the lead screw 23. An electric push rod 25 is fixedly installed on the sliding block 24. A dirt remover 26 is fixedly connected to the bottom end of the telescopic rod of the electric push rod 25. The dirt remover 26 is used to scrape and push impurities on the filter screen box 14. Wheels 27 are installed on the chassis 1.

[0023] The controller 3 is equipped with indicator lights.

[0024] The controller 3 is equipped with a display screen.

[0025] A pusher 28 is fixedly connected to the chassis 1.

[0026] The working principle of this utility model is as follows: the liquid level sensor is equipped with a first threshold and a second threshold, and the value of the first threshold is greater than the value of the second threshold.

[0027] The first step involves injecting mixed oleic acid into the cryogenic crystallization chamber through the feed pipe. When the liquid level of the mixed oleic acid reaches the first threshold preset by the level sensor, the indicator light on the controller illuminates, stopping the injection of mixed oleic acid. Simultaneously, the cryogenic compressor is activated, using the mixed oleic acid in the crystallization chamber for cryogenic crystallization. The temperature sensor monitors the temperature in the crystallization chamber in real time, and the data is synchronously transmitted to the controller display screen. When the freezing temperature of the mixed oleic acid reaches the threshold preset by the temperature sensor, the first drive motor is activated, driving the stirrer to rotate and agitate the cryogenic crystallization oil, preventing it from solidifying.

[0028] The second step involves controlling the first electric valve to open the feed pipe channel, allowing the cryogenic crystallization oil to flow into the filter box. The filter screen filters the cryogenic crystallization oil, trapping impurities. When the cryogenic crystallization oil level in the box falls below the second threshold preset by the level sensor, the first electric valve closes the feed pipe channel, and the first drive motor stops operating. The pusher is then pushed, causing the wheels to move the chassis. The chassis stops at the designated position, and the finished product container is placed on the mounting plate. Pressing the discharge button opens the second electric valve, allowing the cryogenic crystallization oil to flow into the finished product container, completing the discharge process. When the weight of the cryogenic crystallization oil in the finished product container reaches the threshold preset by the weight sensor, the second electric valve closes the discharge pipe channel. Multiple discharge operations can be performed by repeatedly pressing the discharge button.

[0029] The third step involves pulling the filter screen box after all the frozen crystallization oil has been drained. This allows the filter screen box to slide out of the filter housing. Then, the controller controls the electric push rod to lower the impurity remover to a designated height. Next, the controller operates the second drive motor, which drives the lead screw to rotate. The lead screw moves the sliding block, the electric push rod, and the impurity remover, causing the impurity remover to scrape off the impurities on the filter screen box and push them together. This cleans the filter screen box and prevents impurities from clogging it. After the impurities are collected, the controller controls the second drive motor to work in reverse for a certain period of time and then stops. At the same time, the controller controls the electric push rod to raise the impurity remover to its reset position, and then the impurities are collected and processed again.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
