Description

Technical Field

[0001] The utility model relates to the technical field of emulsion reaction, in particular to an experimental emulsion reaction device for improving stirring efficiency. Background Art

[0002] When our company conducts emulsion reaction experiments, such as the synthesis experiments of water-based emulsions such as paraffin emulsions and emulsified asphalt, we need to use flasks for the reaction. Most flasks are multi-necked flasks such as three-necked flasks and four-necked flasks, which can realize stirring, temperature detection, condensation, feeding and other functions at the same time.

[0003] The stirring of the flask is generally divided into motor stirring, stirring shaft stirring and magnetic stirring. Magnetic stirring is mostly used for non-viscous liquids. Once viscous liquids are stirred, for example, many petrochemical plugging agents, viscosity reducers, lubricants, polymers, paraffin and other liquids with a certain viscosity in our company are stirred and reacted, magnetic stirring is not suitable. Therefore, this application is mainly to improve the motor and stirring shaft stirring currently used by our company.

[0004] The three-necked flask is characterized by a small diameter and a large internal space. When stirring, a stirring blade with a small diameter is often used, which is convenient for inserting into the flask. If the diameter is increased, it cannot be inserted into the flask. However, due to the large internal space of the flask, the stirring efficiency of such a stirring blade is relatively low and the reaction is relatively slow. In addition, the stirring blade will shake during stirring, and flasks are divided into flat-bottomed flasks and round-bottomed flasks. Both flat-bottomed flasks and round-bottomed flasks will shake during stirring. In order to ensure the stability of the flask during reaction, the flask itself needs to be fixed. At present, three-necked flasks are mostly fixed at the diameter when fixed, because the diameter is placed outside, which is convenient for fixing, but the fixing effect is limited and needs to be improved.

[0005] On this basis, the utility model provides an experimental emulsion reaction device with improved stirring efficiency to solve the problem. Utility Model Content

DETAILED DESCRIPTION

[0025] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 5 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the drawings in the specification.

[0026] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0027] An experimental emulsion reaction device for improving stirring efficiency includes a body 1, which is a prior art body. The body 1 has a built-in controller. The body 1 is provided with a temperature control display 37, a speed control switch 38, a control switch 39, such as a power switch, a heating switch, etc., a heat dissipation port 40, a sensor connection port, an operating voltage of 220V / 50Hz, and a timing function can also be set. A vertical rod 2 is provided on the body 1, and the vertical rod 2 is threadedly removably installed on the upper surface of the body 1 or on a subsequent component removably installed on the body 1. A bath pot 3 is placed on the body 1, and the bath pot 3 can be integrated with the body 1 or can be a split type. The bath pot 3 can be made of a transparent material, such as high borosilicate glass, and is mainly used for water bath heating, or it can be a stainless steel bath pot, which can be used for both water bath and oil bath. The bath pot is composed of a 304 stainless steel liner, an insulation layer, and a 304 stainless steel outer shell. An annular heating tube 4 is fixed in the bath pot 3, and the heating tube 4 is connected to a controller and a heating switch in the body 1. The temperature control range is room temperature-400°C, the heating power is 300W-2000W, and the display mode is an LED digital tube or LCD liquid crystal. When conducting an experiment, a three-necked flask 5 is placed in the bath pot 4, and it can also be a four-necked flask or other multi-necked flask. Taking the three-necked flask 5 as an example, the middle diameter is used to place the stirring shaft, one side diameter is a feeding port, and the other diameter is used to place an experimental thermometer, a condenser, etc. When conducting the experiment, a sealing plug is plugged at each caliber. A rotating motor 6 is provided above the middle caliber. The rotating motor 6 is connected to a speed sensor, a controller, and a speed switch. The speed is 0-2600r / min. The rotating motor 6 is connected to a motor connecting rod 36. A cross clamp 35 is first inserted on the vertical pole 2. After being fixed, the motor connecting rod 36 is fixed on the cross clamp 35. A stirring shaft 7 is fixed below the rotating motor 6. A rotating wheel 8 is fixed on the stirring shaft 7. The diameter of the rotating wheel 8 is smaller than the caliber. A plurality of circumferentially evenly distributed receiving grooves 9 are provided on the side wall of the rotating wheel 8. A stirring shaft piece 10 is connected to each receiving groove 9 through a rotating shaft. A coil spring is sleeved on the rotating shaft (blocked and not shown in the figure). The stirring piece 10 initially forms a complete circle with the rotating wheel 8. The stirring shaft 7 is a threaded detachable installation. When installing, first insert the rotating wheel 8 and the stirring shaft 7 into the three-necked flask, and then dock the upper thread of the stirring shaft 7 with the rotating motor 6.

[0028] During the experimental reaction, as the speed of the stirring shaft 7 increases, the stirring blade 10 will extend outward under the centrifugal effect, so that the stirring blade 10 on the rotating wheel 8 rotates out, thereby increasing the stirring range and improving the stirring efficiency. When the stirring is completed, as the rotating wheel 8 gradually stops, the stirring blade 10 slowly returns to its original position under the action of the coil spring.

[0029] Furthermore, a column 11 is fixed at a coaxial position of the bath pot 3, and a thread is provided on the column 11. A fixing device is threadedly installed on the column 11, and the fixing device includes a fixed plate 12. Two symmetrical slide grooves 13 are opened on the fixed plate 12, and a slide plate 14 is slidably installed in the slide groove 13. A clamping plate 16 is fixed to the end of the slide plate 14, and a sliding shaft 15 is fixed to the lower end of the slide plate 14. A fixing tube 20 is coaxially fixed to the lower end of the fixed plate 12, and the fixing tube 20 is threadedly connected to the column 11. An adjusting gear 17 is rotatably installed on the fixing tube 20, and two symmetrical arc-shaped adjusting holes 18 are opened on the adjusting gear 17. The sliding shaft 15 slides in the adjusting hole 18, and the adjusting gear 17 is meshed with a wave gear 19. Part of the wave gear 19 is placed on the outer side of the fixed plate 12 for convenient manual fluctuation.

[0030] Since the heating tube 4 is at the bottom of the bath pot 3, each time the three-necked flask 5 is placed, the flask and the heating tube 4 often collide, causing damage to the heating tube 4 and the flask. The heating tube 4 directly contacts and heats the flask. After repeated use, it will leave marks on the flask wall. At the same time, the scale on the heating tube 4 will adhere to the flask wall and is difficult to clean. Therefore, when conducting the reaction, the fixed tube 20 on the fixed disk 12 is first fixed on the column 11. At this time, the fixed disk 12 and the adjusting gear 17 are placed above the heating tube 4 to avoid direct contact between the heating tube 4 and the flask. The flask is placed on the fixed disk 12, and the wave gear 19 is turned by hand. The wave gear 19 engages with the adjusting gear 17 to rotate. The adjusting gear 17 rotates and drives the adjusting hole 18 to push the sliding shaft 15 to move in the adjusting hole 18. The adjusting hole 18 drives the clamping plate 16 to clamp and fix the bottom of the flask, and then water is added to the bath pot 3.

[0031] Furthermore, a tube clamp 22 is removably mounted on the vertical pole 2, and a cross bar 23 is fixed to one end of the tube clamp 22 facing the flask, an adjusting screw 24 is rotatably mounted on the cross bar 23, a knob is fixed to one end of the adjusting screw 24, and threads with opposite threads are arranged at both ends of the adjusting screw 24, a limiting rod 25 passing through the cross bar 23 is fixed at the front end of the adjusting screw 24, and two symmetrical clamp rings 26 are threadedly connected to both ends of the adjusting screw 24, and the limiting rod 25 passes through the two clamp rings 26 for limiting.

[0032] The clamp ring 26 is used to fix the upper end of the three-necked flask to maintain the stability of the upper end of the three-necked flask. After the flask is ready, the adjusting screw 24 is rotated, and the adjusting screw 24 drives the two clamp rings 26 to move inward to clamp and fix the upper end of the three-necked flask 5.

[0033] Furthermore, a pot cover 27 is buckled on the upper end of the bath pot 3, and a pot mouth 28 is opened on the pot cover 27 for placing a flask. Both ends of the pot cover 27 are provided with plug holes 29 connected to the inside of the bath pot 3. The plug holes 29 are used to place a liquid level sensor 31, model XK-136P and a temperature sensor 30, model PT100. The temperature sensor 30 and the liquid level sensor 31 are connected to a docking hole 32 at the rear of the body 1, and the docking hole 32 is connected to the built-in sensor and switch.

[0034] The temperature sensor 30 is used to detect the temperature of the liquid in the bath pot 3, and the liquid level sensor 31 is used to detect the height of the liquid level in the bath pot 3 to prevent dry burning.

[0035] Furthermore, a heat sink 33 is fixed at the upper end of the machine body 1 for heat dissipation of the bath pot 3. The vertical rod 2 is fixed on the heat sink 33. A placement groove 34 is provided on the heat sink 33. The bath pot 3 is placed in the placement groove 34. The bath pot 3 can be integrated with the placement groove 34 or separated.

[0036] The utility model installs a stirring piece which can be stored and centrifugally rotated on the rotating wheel, so that the stirring shaft can be conveniently placed in the three-necked flask. At the same time, when the reaction is carried out, the stirring range can be increased and the stirring efficiency can be improved. After the reaction is completed, the stirring piece can be restored to its original position and can be conveniently taken out.

[0037] The utility model also adds a fixing device in the bath pot to prevent the flask from being damaged by collision with the heating tube, and to prevent marks or scale from being left on the wall of the flask. At the same time, the fixing device can also fix the bottom of the flask to ensure the stability of the three-necked flask during the reaction. The opening at the upper end of the flask can also be fixed by adjusting the screw rod, so that both the upper end and the lower end of the flask can be fixed, further ensuring the stability of the flask.
