[0027] See also Figure 3 and Figure 4 The filter assembly 6 includes a filter plate 601 and a mounting cover 602 installed on the top of the filter plate 601. A mounting ring 10 for connecting the filter assembly 6 is also fixedly installed on the inner wall of the kettle body 1. An arc groove 11 is provided on the top of the mounting ring 10. A slot 12 is provided on the inner wall at one end of the arc groove 11. An arc block 13 adapted to the arc groove 11 is fixedly installed on the bottom of the mounting cover 602. An insert block 14 adapted to the slot 12 is fixedly installed on one end of the arc block 13.

[0028] See also Figure 5 and Figure 6 A positioning assembly for positioning the arc block 13 is also provided on the surface of the kettle body 1, and the positioning assembly includes a fixed block 15 fixedly installed on one side of the kettle body 1, and a positioning rod 24 extending into the arc groove 11 is inserted on the side of the fixed block 15 away from the kettle body 1, and a fixed cover 16 is fixedly installed on the inner wall of the fixed block 15, and a push block 18 is slidably installed on the inner wall of the fixed cover 16, and a push rod 17 extending to the outside of the fixed block 15 is fixedly installed on one side of the push block 18, and a slot 19 is also provided inside the positioning rod 24, and a spring 20 is fixedly installed on the inner wall of the slot 19, and a movable block 21 is fixedly installed on one end of the spring 20, and a clamping block 22 is fixedly installed on the other side of the movable block 21.

[0029] During use of the device, low-content sodium formate is fed into the kettle body 1 through the second feed pipe 3, and then methanol is added from the first feed pipe 2 to dissolve organic impurities contained in the low-content sodium formate in the methanol, and then nitrogen is added through the air inlet pipe 27, and the methanol solution containing dissolved organic impurities is filtered through the filter plate 601, and the liquid is discharged from the slag discharge pipe 5 to obtain sodium formate with a qualified content. After the purification of sodium formate is completed, methanol is added from the first feed pipe 2, and then mixed by a stirring component.

Compared with the production of sodium formate by synthetic methods on the market, its production cost is lower, and it only needs to regularly inspect and maintain the filter plate 601, and the maintenance cost is lower.

[0030] In addition, when it is necessary to disassemble the filter plate 601, pull the positioning rod 24 outward. When the position of the slot 19 is aligned with the fixed cover 16, the block 22 will move toward the inside of the fixed cover 16 under the elastic force of the spring 20, so that the positioning rod 24 is positioned. At this time, the positioning rod 24 has also been separated from the arc groove 11. Rotate the mounting cover 602 to make the arc block 13 slide inside the arc groove 11. When the plug block 14 is separated from the slot 12, the filter plate 601 can be removed for inspection and maintenance.

[0031] During installation, it is only necessary to insert the arc block 13 into the arc groove 11, and then rotate the installation cover 602 to insert the insert block 14 into the slot 12, and then push the push rod 17 to reset the block 22. When the positioning rod 24 is no longer restricted, insert the end of the positioning rod 24 into the arc groove 11, thereby completing the installation of the filter plate 601. The operation is simple and convenient, which greatly improves the competitiveness of the product.

[0032] In this embodiment, the stirring assembly includes a motor 7 fixedly mounted on the top of the kettle body 1 , a rotating rod 8 extending into the interior of the kettle body 1 is fixedly mounted on the output end of the motor 7 , and a stirring rod 9 is fixedly mounted on the surface of the rotating rod 8 .

A second fixed frame 32 is fixedly installed on the surface of the upper kettle 101. The second fixed frame 32 is fixed to the output end of the hydraulic rod 31.

[0039] Among them, by setting the kettle body 1 into two parts, and then using the hydraulic rod 31 to drive the upper kettle 101 to move, it is convenient for the equipment to remove the filter plate 601 when cleaning and maintaining the filter plate 601, thereby further improving its maintenance efficiency.

[0040] In addition, the docking groove 34 and the docking block 33 are provided to facilitate docking between the upper kettle 101 and the lower kettle 102. At the same time, the detachable design of the upper kettle 101 and the lower kettle 102 also facilitates cleaning of the interior thereof, thereby improving the practicability of the device.

[0041] When the present embodiment is in use, low-content sodium formate is fed into the kettle body 1 through the second feed pipe 3, and then methanol is added from the first feed pipe 2 to dissolve organic impurities contained in the low-content sodium formate in the methanol, and then nitrogen is added through the air inlet pipe 27, and the methanol solution containing dissolved organic impurities is filtered through the filter plate 601, and the liquid is discharged from the slag discharge pipe 5 to obtain sodium formate with a content that meets the standard. After the purification of sodium formate is completed, methanol is added from the first feed pipe 2, and the motor 7 is started to drive the stirring rod 9 to stir so that it is fully mixed. After the mixing is uniform, it is discharged from the discharge pipe 4 into the subsequent process. Compared with the production of sodium formate by synthetic methods on the market, its production cost is lower, and it only needs to regularly inspect and maintain the filter plate 601, and the maintenance cost is lower.

[0042] When the filter plate 601 needs to be disassembled, the positioning rod 24 is pulled outward. When the position of the slot 19 is aligned with the fixing cover 16, the block 22 will move toward the inside of the fixing cover 16 under the elastic force of the spring 20, so that the positioning rod 24 is positioned. At this time, the positioning rod 24 has also been separated from the arc groove 11, and the installation cover 602 is rotated to make the arc block 13 slide inside the arc groove 11. When the plug block 14 is separated from the slot 12, the filter plate 601 can be removed for inspection and maintenance; during installation, it is only necessary to insert the arc block 13 into the inside of the arc groove 11, and then rotate the installation cover 602 to insert the plug block 14 into the inside of the slot 12, and then push the push rod 17 to reset the block 22. When the positioning rod 24 is no longer limited, the positioning rod 24 will be reset under the suction of the first magnetic block 25 and the second magnetic block 26, so that the end of the positioning rod 24 is inserted into the inside of the arc groove 11, thereby completing the installation of the filter plate 601. The operation is simple and convenient, which greatly improves the competitiveness of the product.
