Description

Technical Field

[0001] This utility model relates to the field of fatty acid crystallization technology, specifically to a visual monitoring device for fatty acid crystal particle size. Background Technology

[0002] A fatty acid crystallization device is a specialized piece of equipment for crystallizing fatty acid materials. It is commonly used in fields such as oil production. The crystallization vessel is the main site for fatty acid crystallization and is usually designed as a cylindrical jacketed cylinder. Water with adjustable temperature is circulated through the jacket to facilitate temperature control during the crystallization process.

[0003] In the current process of crystallizing fatty acids in a crystallizer, the particle size of the fatty acid crystals needs to be monitored by an industrial camera. However, due to the low temperature inside the crystallizer, there is a temperature difference between the inside and outside of the transparent glass used for monitoring. This causes water vapor to form on the outside of the transparent glass, which obscures the transparency of the glass and affects the monitoring image of the industrial camera. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a visual monitoring device for fatty acid crystal particle size, which solves the problem of water vapor forming on the outside of transparent glass due to temperature differences between the inside and outside of the transparent glass, thus obscuring the transparency of the glass.

[0006] Preferably, the top of the fixed cover is rotatably connected to a rotating rod through an opening, and a plurality of rotating sleeves are fixedly connected to the surface of the rotating rod, and a plurality of stirring plates are fixedly connected to the surface of the rotating sleeves.

[0008] Preferably, a scraper strip is fixedly installed at the rear of the scraper.

[0009] Preferably, the top of the fixed cover is connected to a liquid inlet pipe.

[0010] Preferably, a liquid outlet pipe is connected to the lower side of one side of the crystallization vessel body.

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a visual monitoring device for fatty acid crystallization particle size, including a crystallization vessel body 1, a cooling tank 2 on the top of the crystallization vessel body 1, a fixed cover 3 fixedly connected to the top of the crystallization vessel body 1, a feeding pipe connected to the top of the fixed cover 3, a discharge pipe connected to the bottom of the crystallization vessel body 1, a monitoring frame 4 fixedly connected to the front of the crystallization vessel body 1 through an opening, a transparent glass 5 fixedly installed on the front of the monitoring frame 4, and an industrial camera 6 fixedly installed on the monitoring frame 4 by a fixing bracket. The industrial camera 6 is a Basler ace. The acA2000-165um monitoring frame 4 has a drive frame 7 fixedly connected to one side via a connecting plate. The bottom of the inner cavity of the drive frame 7 is rotatably connected to a reciprocating screw 8 via a bearing. A motor 9 is fixedly connected to one side of the drive frame 7 via a mounting bracket. The motor 9 is a servo motor, electrically connected to an external power source, and controlled by a control switch. The output shaft of the motor 9 is fixedly connected to one end of the reciprocating screw 8 via a coupling. A threaded sleeve 10 is provided on the surface of the reciprocating screw 8. A sliding groove 11 is provided at the front of the drive frame 7. A sliding block 12 is slidably connected inside the sliding groove 11. The rear of the sliding block 12 is fixedly connected to the threaded sleeve 10. A scraper 13 for use with transparent glass 5 is fixedly connected to the front of the sliding block 12.

[0021] It should be noted that during the process of monitoring the particle size of fatty acid crystals through the transparent glass 5, the industrial camera 6 captures the image when the scraper 13 is positioned above and below the industrial camera 6 to ensure the clarity of the monitoring image captured by the industrial camera 6.

[0022] Furthermore, in order to ensure the uniformity of fatty acid crystallization in the crystallizing vessel body 1, a rotating rod 14 is rotatably connected to the top of the fixed cover 3 through an opening. Several rotating sleeves 15 are fixedly connected to the surface of the rotating rod 14, and several stirring plates 16 are fixedly connected to the surface of the rotating sleeves 15. Transmission wheels 17 are fixedly connected to both the surface of the reciprocating screw 8 and the surface of the rotating rod 14, and a transmission belt 18 is connected between the surfaces of the two transmission wheels 17.

[0023] Furthermore, in order to better clean the water mist on the transparent glass 5, a scraper 21 is fixedly installed at the rear of the scraper 13. The scraper 21 is made of rubber.

[0024] Furthermore, to facilitate the addition and discharge of coolant to the crystallization vessel body 1, the top of the fixed cover 3 is connected to an inlet pipe 19, and the bottom of one side of the crystallization vessel body 1 is connected to an outlet pipe 20.

[0025] In use, fatty acids are added to the crystallizer body 1 through the feeding pipe, and coolant is added to the cooling tank 2 through the liquid inlet pipe 19. The coolant is then discharged through the liquid outlet pipe 20. The coolant cools and crystallizes the fatty acids in the crystallizer body 1. At the same time, the motor 9 drives the reciprocating screw 8 to rotate. The reciprocating screw 8 drives the rotating rod 14 to rotate through the transmission wheel 17 and the transmission belt 18. The rotating rod 14 drives multiple rotating sleeves 15 to rotate. The multiple rotating sleeves 15 drive multiple stirring plates 16 to rotate, so that the multiple stirring plates 16 agitate the fatty acids and ensure the uniformity of fatty acid crystallization. The fatty acid crystal particles in the crystallizer body 1 are then photographed and monitored by the industrial camera 6.

[0026] While the reciprocating screw 8 is rotating, it will drive the threaded sleeve 10 to move slowly up and down. The threaded sleeve 10 will drive the scraper 13 to move slowly up and down through the sliding block 12. The scraper 13 will drive the scraper 21 to move slowly up and down. The scraper 21 will scrape the front of the transparent glass 5 to remove the water mist in front of the transparent glass 5.
