Description

Technical Field

[0001] The utility model relates to the technical field of concentrator-related equipment, in particular to a single-effect concentrator which is convenient for draining liquid. Background Art

[0002] A single-effect concentrator is a device that can efficiently and conveniently remove concentrated liquid during the evaporation and concentration process of a solution. This device is widely used in traditional Chinese medicine extraction, biopharmaceutical product extraction, and other industries that require solution purification. The working principle of the single-effect concentrator mainly relies on a combination of external heating natural circulation and vacuum negative pressure evaporation. When the raw steam enters the heating chamber, the feed liquid is heated and rises, and then sprayed into the evaporation chamber from the nozzle for gas-liquid separation. The feed liquid returns to the lower part of the heating chamber in the circulation pipe and is heated again, and this cycle continues until the feed liquid is concentrated to a certain degree.

[0003] For example, a single-effect concentrator that is easy to drain, with publication number CN207694273U, includes a concentrator body, a liquid inlet pipe and an air purifier. The outside of the concentrator body is provided with an interlayer through a sealed shell, the liquid inlet pipe is fixedly installed on the top of the concentrator body through a mounting seat, a liquid discharge pipe is provided at the bottom of the concentrator body, a through hole is provided around the concentrator body corresponding to the liquid inlet pipe, the side of the sealed shell is connected with an input pipe through a connecting seat, the output end of the air purifier is connected to the input end of the input pipe, and an activated carbon purification core plate is provided inside the air purifier. This single-effect concentrator that is easy to drain has the advantages of being easy to use and effectively facilitating the discharge of concentrated liquid inside the concentrator body, and solves the problem that bacteria and dust are easily introduced into the concentrator body when the concentrated liquid is discharged, which affects the quality of the concentrated liquid.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that although the above device can reduce the impact of dust to a certain extent, in actual use, since the concentrated material is relatively viscous, conventional drainage methods are prone to clogging. The above device lacks effective drainage capacity and is prone to affecting the collection efficiency when used.

[0005] Therefore, in order to solve the above problems, a single-effect concentrator which is convenient for draining liquid is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is that the prior art has the disadvantage of weak drainage capability, for which we propose a single-effect concentrator which is convenient for drainage.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a single-effect concentrator that is easy to discharge liquid, including a concentration tank; a drainage mechanism is arranged at the bottom of the concentration tank, and the drainage mechanism includes an upper connecting plate, and the surface of the upper connecting plate is provided with fixing holes, and a material introduction frame is fixedly installed at the bottom of the upper connecting plate, and a feed roller is movably installed inside the feed introduction frame, and the top of the feed roller is movably connected to a driving motor, and a first reinforcement plate is fixedly installed on the outside of the driving motor, and a negative pressure box is screwed to the bottom of the feed introduction frame, a vacuum pump is fixedly installed on one side of the negative pressure box, and a second reinforcement plate is fixedly installed on the outside of the vacuum pump.

[0008] Preferably, a discharge hopper is fixedly mounted at the bottom of the negative pressure box, and a guard plate is movably mounted at the bottom end of the discharge hopper.

[0009] Preferably, a control panel is fixedly mounted on the front of the concentration tank, and operation buttons are arranged on the surface of the control panel.

[0010] Preferably, an air inlet pipe is fixedly installed on the top of the concentration tank, and the other end of the air inlet pipe is fixedly connected to a liquefaction tank.

[0011] Preferably, a water storage tank is fixedly installed at the bottom of the liquefaction tank, and a water outlet pipe is fixedly installed at one side of the bottom of the water storage tank.

[0012] Preferably, a feed flange is fixedly mounted on the back of the concentration tank, and a heating tank is fixedly connected to the other side of the concentration tank.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model provides a place for concentrating materials through the setting of a concentration tank, and facilitates users to better guide the concentrated viscous materials out of the tank through the setting of a drainage mechanism. The drainage mechanism is composed of two parts. The upper part is a material guide frame, and a feed roller that can be controlled by a driving motor is arranged in the material guide frame. The impeller on the surface of the feed roller is specially arranged, which can better push the thick material to be discharged outward. The lower part is a negative pressure box, which can generate a pressure difference between the upper and lower parts, so as to better guide the material to be discharged to the outside. The setting of a vacuum pump facilitates the release of air in the negative pressure box, so that a pressure difference is generated between the negative pressure box and the upper space, thereby further reducing the impact caused by the stickiness of the material.

The utility model can better guide the material to be discharged from the hopper mouth through the setting of the discharge hopper, so as to facilitate the user to take the material statically and accurately. The setting of the control panel and the operation buttons can facilitate the user to electrically control the device. The setting of the air inlet pipe can facilitate the introduction of steam into the liquefaction tank. The setting of the water storage tank can facilitate the temporary storage of liquefied steam. The setting of the water outlet pipe can facilitate the user to discharge excess liquefied water. The setting of the feed flange can facilitate the introduction of materials that need to be concentrated. The setting of the heating tank can facilitate the generation of high-temperature gas for concentrating the materials. BRIEF DESCRIPTION OF THE DRAWINGS

The air in the negative pressure box 207 is released through the vacuum pump 208, so as to generate a pressure difference between the negative pressure box 207 and the upper space, thereby further reducing the impact caused by the sticky material.
