By pulling the pull rod 250, the top cover 200 can be moved and separated from the top of the box 100. The rubber sleeve 250a can increase the friction between the hand and the pull rod 250.

[0032] The tank body 300 is located inside the box body 100 and connected to the motor 210, and is driven to rotate by the motor 210. An outer fixing sleeve 310 is installed on the outer wall of the tank body 300, and the bottom of the outer fixing sleeve 310 abuts against the top of the support plate 110. A through hole 320 is opened at the bottom of the tank body 300, and the through hole 320 is connected to the collection box 120. The bottom of the inner part of the tank body 300 has a slope 320a. The output end of the motor 210 extends out of the bottom of the top cover 200 and is equipped with a rotating rod 210a. A first gear 210a-1 is installed at the bottom of the rotating rod 210a. A first annular rack 310a is installed at the top of the tank body 300. The first annular rack 310a meshes with the first gear 210a-1. A first reciprocating threaded rod 220 is rotatably connected to the bottom of the top cover 200. A second gear 220a is installed at the end, and the second gear 220a meshes with the first annular rack 310a. When the top cover 200 is located at the top of the box 100, the first gear 210a-1 meshes with the first annular rack 310a. Not shown in the figure, when the top cover 200 is located at the top of the box 100, the rotating rod 210a and the first reciprocating threaded rod 220 are both located above the tank 300.

When the first reciprocating threaded rod 220 rotates, it uses the screw structure to push the floating plate 430 to move up and down. When the floating plate 430 moves, it drives the connecting rod 420 and the scraper 400 to move up and down. When the scraper 400 moves, it scrapes off the sodium chloride crystals attached to the inner wall of the tank 300 and collects them in the collection box 120 through the slope 320a at the bottom of the tank 300.

[0034] A second annular rack 310b is installed on the outer wall of the outer fixing sleeve 310. A second fixing plate 130 is installed on the side wall of the housing 100. A second reciprocating threaded rod 130a is rotatably connected to the bottom of the second fixing plate 130. A first pulley 130a-1 is rotatably connected to the top of the second fixing plate 130. The first pulley 130a-1 and the second reciprocating threaded rod 130a are coaxially fixedly connected. A third gear 130b is also rotatably connected to the top of the second fixing plate 130. The third gear 130b meshes with the second annular rack 310b. A second... The first pulley 130a-1 is connected to the second pulley 130b-1 via a belt. The cleaning assembly 500 includes a fixed tube 510 installed on the side wall of the housing 100 and a piston 520 located inside the fixed tube 510.

The pipe body is equipped with a second one-way valve 510b-1, and the piston 520 has a second fixed rod 520a installed on its top. The second fixed rod 520a has a second reciprocating threaded hole 520a-1 at its top. The second reciprocating threaded rod 130a rotates into the second reciprocating threaded hole 520a-1. When the tank body 300 rotates, the second annular rack 310b drives the third gear 130b and the second pulley 130b-1 to rotate. The second pulley 130b-1 uses a belt to drive the first pulley 130a-1 and the second reciprocating threaded rod 130a to rotate. When the screw rod 130a rotates, it uses a screw structure to drive the second fixed rod 520a and the piston 520 to move up and down inside the fixed tube 510. When the piston 520 moves upward, the first one-way valve 510a-1 opens and the second one-way valve 510b-1 closes. The first hose 510a draws sodium chloride from the collection box 120 into the fixed tube 510. When the piston 520 moves downward, the first one-way valve 510a-1 closes and the second one-way valve 510b-1 opens. At this time, the sodium chloride inside the fixed tube 510 is discharged through the second hose 510b.

[0035] Combination Figures 1-5This embodiment of a sodium chloride removal device for the production of chloromethyl isopropyl carbonate involves pouring the solution into the tank 300, then covering the top of the housing 100 with the top cover 200, sealing the top of the housing 100. At this time, the scraper 400 is located inside the tank 300. The motor 210 is started, driving the first gear 210a-1 to rotate, which in turn drives the tank 300 to rotate. While the tank 300 rotates, the connecting rod 420 stirs the solution inside the tank 300, and simultaneously drives the second gear... The wheel 220a and the first reciprocating threaded rod 220 rotate, and the first reciprocating threaded rod 220 drives the floating plate 430 and the scraper 400 to move up and down, scraping off the sodium chloride crystals adhering to the inner wall of the tank 300 and collecting them inside the collection box 120. At the same time as the tank 300 rotates, the second annular rack 310b drives the third gear 130b to rotate, which in turn drives the second reciprocating threaded rod 130a to rotate, pushing the piston 520 to move up and down reciprocally inside the fixed tube 510, discharging the sodium chloride collected inside the collection box 120.
