Description

Technical Field

[0001] This utility model relates to the field of continuous distillation equipment technology, specifically to a laboratory continuous redistillation water apparatus. Background Technology

[0002] Multistage distillation technology is a core method for separation and purification in both laboratory and industrial fields, and its device design directly affects experimental efficiency and ease of operation. Traditional multistage distillation devices typically employ fixed supports and bolted positioning structures, with each distillation unit connected in series via welding or complex piping. This results in bulky equipment, cumbersome assembly processes, and difficulty in meeting the needs for rapid deployment and flexible adjustment. Furthermore, it cannot adapt to different raw material quantities or experimental conditions. For example, small-scale experiments require a complete device, leading to reagent waste, while large-scale experiments require multiple sets of equipment in parallel due to insufficient capacity. Therefore, we propose a laboratory continuous redistillation water device. Utility Model Content

A positioning plate is fixedly provided on one outer wall of the top of the strip-shaped fuel box, and two parallel threaded limiting rods are fixedly provided on one outer wall of the positioning plate. Two connecting pipes are fixedly provided on one outer wall of the distillation box through an opening. The outer wall of the threaded limiting rod is slidably connected to the inner wall of the connecting pipe. Two vertically upward gas guide pipes are fixedly provided on the top of the distillation box through an opening. A pipe connector is fixedly provided on the top outer wall of the two gas guide pipes. A U-shaped conduit is connected to the gas guide pipe on the top of adjacent distillation boxes through the pipe connector. A condenser is installed on one side of the bottom of the U-shaped conduit.

[0005] Preferably, the top of the distillation box has equally spaced through holes, and the inner wall of the through holes is fitted with a vertical heating pipe.

[0022] Example 1

[0023] Refer to the instruction manual appendix Figure 1-4 The laboratory continuous redistillation water apparatus includes a strip-shaped fuel box 1, with the strip-shaped fuel box 1 as the core heat source. Four distillation boxes 2 are evenly distributed on the top. Each distillation box 2 forms an efficient heat conduction path with the combustion zone of the strip-shaped fuel box 1 through 10 vertical heating pipes 16 inside the top through-hole. A positioning plate 3 is vertically welded to the outer left wall of the strip-shaped fuel box 1. Two threaded limiting rods 4 extending from the plate form a sliding pair with the connecting pipes 5 on the side wall of the distillation box 2. The height of the distillation box 2 is achieved by tightening the wing nut 17. The gas guide pipes 6 of adjacent distillation boxes 2 are connected in series with U-shaped conduits 8 through pipe joints 7. A condenser 9 is installed at the lower end of the U-shaped conduit 8, forming a four-stage continuous distillation circuit. Ten retaining rings 10 are arranged along the length of the top of the strip-shaped fuel box 1. Each retaining ring 10 has a ceramic fiber woven wick 11 embedded in it. The positioning ring 12 and the cap 13 form an anti-evaporation and flame control structure. The cap 13 is made of high-temperature resistant metal and has a fireproof and heat-insulating layer on its inner surface. After being tightened by threads, it can completely cover the top opening of the retaining ring 10, which not only prevents fuel evaporation but also extinguishes the flame by isolating oxygen in an emergency. The fuel filling pipe 14 is equipped with a threaded sealing cap 15 for fuel replenishment.

[0024] Example 2

[0025] Based on Example 1, the basic structure is optimized into a five-stage distillation system. The number of distillation boxes 2 is increased to five, and a 316L stainless steel one-piece molding process is used to improve the corrosion resistance of distillation boxes 2 under high temperature and high pressure environments. The surface of the threaded limit rod 4 is nitrided, and the wing nut 17 is equipped with anti-slip texture. The U-shaped conduit 8 is made of quartz glass, and the condenser 9 has a built-in spiral titanium alloy tube to enhance heat exchange efficiency. The spacing of the 10 fixing rings 10 is optimized to an equidistant 70mm layout. The wick 11 adopts a two-layer structure, with a high-temperature resistant fiber outer layer and an oil-absorbing cotton core inner layer. The positioning ring 12 is equipped with a fluororubber sealing ring, and the cap 13 is changed to a rotary snap-on quick-release structure with a copper heat-insulating bushing added to its inner surface, allowing for rapid cooling through metal heat conduction when extinguishing the flame. The liquid filling pipe 14 is extended to 250mm and equipped with a self-sealing funnel interface. A spark-proof labyrinth sealing groove is designed at the joint between the cap 13 and the positioning ring 12 to further improve safety.

[0026] Working principle of this utility model:

[0027] Refer to the instruction manual appendix Figure 1-4 First, unscrew the sealing cap 15 of the filling pipe 14, inject fuel into the strip fuel box 1 through the funnel, and then tighten the sealing cap; remove the cap 13, ignite the wick 11 with the igniter, and the flame heats the vertical heating pipe 16 through the fixing ring 10; align the connecting pipe 5 of the distillation box 2 with the horizontally arranged threaded limit rod 4, slide it along the rod to the appropriate position, and then tighten the wing nut 17 to fix it; connect the inlet and outlet of the condenser 9 and start the circulation pump to ensure that the U-shaped guide tube 8 is completely covered by condensate; after the temperature in the distillation box 2 rises to the set value, inject raw water from the top, and after four-stage distillation, pure water is output from the condenser 9; if it is necessary to extinguish the flame in an emergency, the cap 13 can be tightened directly to cover the fixing ring 10, and pressure extinguishing is achieved by isolating oxygen. Throughout the operation, the sealing of the positioning ring 12 and the cap 13 must be ensured to prevent fuel leakage.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
