Description

Technical Field

[0001] The utility model belongs to the technical field of disinfectant production, in particular to a secondary distillation device for wood vinegar disinfectant. Background Art

[0002] Wood vinegar is a natural plant material extracted by high-tech biochemical extraction. It contains more than 200 kinds of organic matter, the main components of which are acetic acid, phenols and water, of which the organic component acetic acid accounts for more than 10%. This product has strong bactericidal and antibacterial functions at high concentrations; it can inhibit the reproduction of miscellaneous bacteria at low concentrations and has antibacterial and anti-insect effects.

[0003] The preparation of wood vinegar disinfectant comprises the following steps: 1. using the branches of broad-leaved trees grown at 46° north latitude for more than 100 years to perform dry distillation and pyrolysis to derive a steam-gas mixture, which is condensed and separated to obtain a reddish-brown liquid; 2. pouring the reddish-brown liquid obtained in step 1 into a container, standing and aging for 3 to 5 years, and collecting the clarified part in the middle to obtain a crude wood vinegar liquid; 3. distilling the crude wood vinegar liquid obtained in step 2 again at normal pressure, collecting the fraction at 98°C to 103°C, thus obtaining the desired wood vinegar liquid, and finally blending the crude wood vinegar disinfectant liquid.

[0004] When the crude wood vinegar is distilled again, a distillation kettle is usually used in the prior art to heat and distill it. However, the existing distillation kettle lacks an insulation component for the wood vinegar vapor, so that when the wood vinegar vapor rises to the upper end of the distillation kettle and accumulates on the kettle wall, it will liquefy into more water droplets due to the decrease in temperature and fall back into the crude wood vinegar, resulting in low efficiency in collecting the distilled fractions. In view of this, the utility model is specially proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 3 The secondary distillation device of wood vinegar disinfectant comprises an electric oil bath pot 1, on which a placement port is provided, and further comprises: a distillation kettle 2, which is installed in the electric oil bath pot 1 through the placement port; the upper end of the distillation kettle 2 is connected with a delivery pipe 201; a circle of heat-insulating oil chamber 205 is provided in the kettle wall near the upper end of the distillation kettle 2 and the delivery pipe 201; a suction pump 3 is fixedly installed on one side of the electric oil bath pot 1; an oil extraction pipe 301 and an oil delivery pipe 302 are respectively connected with the oil inlet and outlet of the suction pump 3, and one end of the oil delivery pipe 302 away from the suction pump 3 is connected with the heat-insulating oil chamber 205; the electric oil bath pot 1 and the heat-insulating oil chamber 205 are connected through an oil return pipe 303.

[0022] A motor 4 is fixedly installed at the bottom of the electric oil bath pot 1, and the output shaft of the motor 4 extends upward into the electric oil bath pot 1. A rotating rod 401 is vertically rotatably connected in the distillation kettle 2, and multiple rows of stirring rods 402 are equidistantly installed on the rotating rod 401. The lower end of the rotating rod 401 penetrates downward into the distillation kettle 2 and is connected to the output shaft of the motor 4.

[0023] When it is necessary to distill the crude wood vinegar to obtain the final wood vinegar, the staff can add the crude wood vinegar into the still 2 through the delivery pipe 201, and then connect the delivery pipe 201 to the external condenser, and then start the electric oil bath 1, and use the heat-conducting oil in the electric oil bath 1 to heat and distill the crude wood vinegar. When the crude wood vinegar is heated, the motor 4 can be started, and the motor 4 can drive the rotating rod 401 to rotate, and the rotating rod 401 will drive the multiple rows of stirring rods 402 to rotate, so that the crude wood vinegar in the still 2 can be stirred, and the uniformity of its heating is improved, which effectively improves the distillation and purification efficiency of the crude wood vinegar. When the crude wood vinegar is heated and boiled to generate steam, the steam will float upward and enter the condenser along the delivery pipe 201 for condensation, and then it can be condensed into liquid, that is, the required wood vinegar.

[0024] While the crude wood vinegar is being heated, the suction pump 3 is started, and the suction pump 3 will transport part of the heat transfer oil in the electric oil bath 1 into the heat preservation oil chamber 205 opened at the upper end of the still 2 through the oil extraction pipe 301 and the oil delivery pipe 302, so as to heat and insulate the still wall at the upper end of the still 2. Therefore, when the steam rises and accumulates on the still wall at the upper end of the still 2, the steam can be insulated, and the amount of water droplets generated by the steam in the still 2 can be reduced, which can not only improve the efficiency of the distillation preparation of the wood vinegar, but also reduce the content of the steam liquefied and residual in the still 2, and effectively improve the collection rate of the wood vinegar.

[0025] Embodiment 2:

[0026] Reference Figure 1-Figure 3 The secondary distillation device for wood vinegar disinfectant is basically the same as that of Example 1, and further, the upper end of the rotating rod 401 is fixedly connected to a plurality of scraping strips 404 at equal intervals in a circle through a bracket 403, and the scraping strips 404 slide and stick to the upper inner wall of the still 2. When the motor 4 drives the stirring rod 402 to stir the wood vinegar through the rotating rod 401 to improve the distillation efficiency of the wood vinegar, the motor 4 can also drive the scraping strips 404 to scrape the upper inner wall of the still 2 through the rotating rod 401 and the bracket 403, so that the steam condensed into water droplets on the upper inner wall of the still 2 can be scraped off, so that it falls back into the wood vinegar to participate in the distillation, thereby avoiding the waste caused by the residue of part of the wood vinegar on the upper inner wall of the still 2, and effectively improving the collection rate of the wood vinegar production.

[0027] The distillation kettle 2 and the electric oil bath pot 1 are detachably connected via threads, a rotating handle 204 is fixedly installed on the outer side of the upper end of the distillation kettle 2, a polygonal protrusion is provided at the lower end of the rotating rod 401, and a polygonal slot for use with the polygonal protrusion is provided on the output shaft of the motor 4. By making the distillation kettle 2 and the electric oil bath pot 1 detachably connected, when the distillation kettle 2 or the electric oil bath pot 1 needs to be repaired separately, they can be separated, providing convenience for maintenance personnel.

[0028] A circle of fixing ring 202 is fixedly connected to the outer side of the distillation kettle 2, and a circle of sealing rubber ring 203 is fixedly connected to the bottom of the fixing ring 202. Through the setting of the fixing ring 202 and the sealing rubber ring 203, when the distillation kettle 2 is installed on the electric oil bath pot 1 through threads, the gap between the distillation kettle 2 and the electric oil bath pot 1 can be sealed, thereby improving the sealing between the distillation kettle 2 and the electric oil bath pot 1, thereby further improving the utilization of heat by the distillation kettle 2.

[0029] The electric oil bath pot 1 and the distillation kettle 2 are both transparent tanks. When the crude wood vinegar is distilled and purified, the staff can check the progress of the distillation of the crude wood vinegar through the electric oil bath pot 1 and the distillation kettle 2 to avoid the problem of burning the bottom.
