Description

Technical Field

[0001] The utility model relates to a reaction kettle, in particular to a reaction kettle convenient for observation. Background Technique

[0002] A reaction kettle is a comprehensive reaction vessel, which is widely used in the chemical reaction process in laboratories and industrial production, including heating, evaporation, cooling, and mixing of materials. It can complete the whole process from feeding to reaction and then to discharging with a high degree of automation, and accurately control the key parameters in the reaction process, such as temperature, pressure, stirring, etc.

[0003] When the raw materials in the reaction kettle rotate and mix at high speed under the drive of the stirring paddle, due to the combined action of the viscosity, surface tension of the liquid and the stirring speed, a large amount of foam, droplets or fine particles are often generated, and these substances are easily splashed onto the observation window of the reaction kettle. As an important window for monitoring the stirring state, reaction process and material changes, the clarity of the observation window is directly related to the operator's judgment and control ability of the reaction process.

[0004] Once the observation window is covered by the splashed slurry, its transparency will drop sharply or even become completely blurred, making it impossible for the staff to observe the stirring state and material changes in the kettle in real time and accurately. In this case, the traditional method is to have to stop the operation of the mixer. After the slurry settles or other measures are taken to clean the observation window, then the observation is carried out. However, this interruption not only affects the production efficiency, but also may have an adverse impact on the reaction process, such as temperature fluctuations, uneven distribution of reactants, etc., and then affects the quality of the final product. Content of the Utility Model

[0005] In order to overcome the shortcoming that when the reaction kettle stirs the raw materials, the raw material slurry is easy to cover the observation window, making it impossible for the staff to immediately observe the stirring degree of the raw material slurry, the utility model provides a reaction kettle convenient for observation.

[0006] The technical solution is: a reaction kettle convenient for observation, including a reaction kettle, an observation window is arranged on the upper part of the reaction kettle, and also includes a mounting plate, a servo motor, a first gear, a second gear, a first slide rail and a scraper. An annular first slide rail is opened on the inner wall of the observation window, the second gear is rotatably connected in the first slide rail, the mounting plate is fixedly connected to the inner wall of the reaction kettle and is located at the corresponding position of the observation window, the servo motor is fixed on the mounting plate, the output shaft of the servo motor is connected with a first gear, the first gear meshes with the second gear, a scraper is arranged in the middle of the second gear, and the scraper is in frictional contact with the inner wall of the observation window.

[0007] Furthermore, it also includes a second slide rail, second slide rails are symmetrically opened on the inner side of the second gear, and the scraper is slidably connected in the second slide rail through a spline.

[0008] Furthermore, it further includes an inspection plate and screws. A through groove is provided on the side of the observation window, the inspection plate is slidably connected in the through groove, and the inspection plate is fixed by screws.

[0009] Furthermore, it further includes magnets. The magnets are divided into a cathode and an anode. The cathode magnet is connected to the end of the scraper, and the anode magnet is connected to the second slide rail.

[0010] Furthermore, it further includes a pull rope. One end of the pull rope is connected to the outer wall of the reaction kettle, and the other end is connected to the inspection plate.

[0011] Furthermore, the inspection plate is provided with a handle.

[0012] Furthermore, an identification card is pasted on the outer wall of the observation window, and the identification card can mark the position of the scraper.

[0013] The beneficial effects are as follows: A rotatable and scouring scraper is added inside the traditional observation window, and the inner wall of the observation window is cleaned by an active cleaning method, enabling the staff to immediately observe the stirring condition of the raw materials in the reaction kettle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solution of the present utility model will be further described below with reference to the drawings.

[0021] Example: A reaction kettle convenient for observation, as Figures 1-5As shown in the figure, it includes a reaction kettle 1. An observation window 2 is arranged at the upper part of the reaction kettle 1. It also includes a mounting plate 3, a servo motor 4, a first gear 5, a second gear 6, a first slide rail 7 and a scraper 8. An annular first slide rail 7 is opened on the inner wall of the observation window 2. The second gear 6 is rotatably connected in the first slide rail 7. The mounting plate 3 is fixedly connected to the inner wall of the reaction kettle 1 and is located at the corresponding position of the observation window 2.
