[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0041] Reference Figure 1-Figure 5 The utility model provides a magnetic reaction kettle, comprising: a cover body 6, a tank body 5, a lifting frame, and a stirring assembly; the cover body 6 can be covered at the top port of the tank body 5 to form a sealed mixing chamber, and raw materials and auxiliary materials are added into the mixing chamber, and the stirring assembly stirs and mixes the raw materials and auxiliary materials in the mixing chamber.
[0042] The cover body 6 is suspended at the action end of the lifting frame, and the opening and closing of the cover body 6 is realized by the lifting action of the lifting frame. When the cover body 6 rises and opens, raw materials and auxiliary materials are added, and when the cover body 6 is lowered and closed with the tank body 5 to form a sealed mixing chamber, a stirring reaction is carried out.
[0043] The stirring assembly includes a driver fixedly connected to the action end of the lifting frame and an agitator rotatably connected to the bottom of the cover body 6. The agitator and the driver transmit rotation by magnetic coupling. The cover body 6 is not provided with an axis mounting hole, so the sealing performance is better. The driver generates a rotational torque, and then transmits the rotation by magnetic coupling to the agitator. The agitator rotates to stir and mix the raw materials and auxiliary materials inside the mixing chamber.
[0044] The agitator comprises: a rotating shaft 10 which can rotate freely relative to the cover body 6, a sliding connection seat 16 is slidably installed on the side of the rotating shaft 10, a fixed connection seat 18 is fixedly installed on the bottom end of the rotating shaft 10, and the distance between the sliding connection seat 16 and the fixed connection seat 18 is changed by sliding the sliding connection seat 16 up and down, and a plurality of annularly distributed double rod groups are installed between the sliding connection seat 16 and the fixed connection seat 18;
[0045] The double rod group comprises a long rod and a short rod, and one end of the long rod is movably connected with one end of the short rod.
[0046] When one end of the long rod away from the short rod is movably connected to the sliding connection seat 16 , and one end of the short rod away from the long rod is movably connected to the fixed connection seat 18 , the double rod group and the rotating shaft 10 form a regular tripod 15 .
[0047] When one end of the long rod away from the short rod is movably connected to the fixed connection seat 18 , and one end of the short rod away from the long rod is movably connected to the sliding connection seat 16 , the double rod group and the rotating shaft 10 form an inverted tripod 20 .
[0048] No matter whether it is a regular tripod 15 or an inverted tripod 20, when the sliding connection seat 16 slides downward, the long rod and the short rod of the double rod group will be close to the rotating shaft 10, so that the distance that the entire agitator extends to the side is smaller, and the area where the mixture adhered to the long rod and the short rod drips downward is smaller (circular area), and this area is located at the center of the tank body 5, so that it will basically not affect the staff to add auxiliary materials into the tank body 5 from the side of the tank body 5.
[0049] The stirrer has at least one regular tripod 15 and at least one inverted tripod 20. The regular tripod 15 stirs the area near the bottom better and stirs the area near the top worse, while the inverted tripod 20 is just the opposite, stirring the area near the bottom worse and stirring the area near the top better. The regular tripod 15 and the inverted tripod 20 are designed at the same time so that the stirrer has a better stirring effect.
[0050] Working principle: in a static state, the sliding connection seat 16 is affected by its own weight and tends to slide downward, so that the sliding connection seat 16 slides downward to the extreme position, driving the long rod and the short rod of the double rod group to an approximately vertical state, which can ensure that the long rod and the short rod are relatively close to the rotating shaft 12. In this state, the cover body 6 and the stirring assembly are raised upward, which can effectively avoid the side extension of the stirring blade affecting the operation of the staff to add auxiliary materials into the reactor.
[0051] When the stirring assembly is rotating (when stirring the mixture), the long rod and the short rod are both affected by the centrifugal force and tend to expand outward, thereby driving the sliding connection seat 16 to slide upward until the short rod is horizontal. At this time, the long rod and the short rod of the double rod group are located on the side of the rotating shaft to form stirring blades to achieve the mixing and stirring function.
[0052] In one embodiment, the number of the regular tripods 15 and the inverted tripods 20 is equal, and the regular tripods 15 and the inverted tripods 20 are staggered. Such design of the regular tripods 15 and the inverted tripods 20 can ensure uniform weight distribution at various positions of the agitator, avoid shaking during high-speed rotation, and balance each part to ensure uniform mixing.
[0053] like Figure 4As shown in FIG. 1 , two groups of regular tripods 15 and two groups of inverted tripods 20 are provided, the two groups of regular tripods 15 are in a straight line shape, the two groups of inverted tripods 20 are in a straight line shape, and the two groups of regular tripods 15 and the two groups of inverted tripods 20 are in a cross shape.
[0054] In one embodiment, the lifting frame includes: a main frame body 1, a cantilever frame 4, and a telescopic member 3.
[0055] The side of the main frame 1 is fixedly connected with a base 2, and the bottom of the tank body 5 is fixedly connected to the base 2, so that the position of the tank body 5 and the lifting frame is fixed, thereby ensuring that the cover body 6 can be well aligned with the tank body 5 every time the cover is closed. The cantilever frame 4 is slidably connected to the main frame 1, and a telescopic part 3 is fixedly installed on the side of the main frame 1, and the telescopic end of the telescopic part 3 is fixedly installed on the cantilever frame 4.
[0056] The telescopic member 3 drives the cantilever frame 4 to slide on the side of the main frame body 1, so as to realize the up and down movement of the cantilever frame 4, thereby driving the cover body 6 to open and close.
[0057] A plurality of suspension posts 7 are fixedly mounted on the top of the cover body 6 , and the suspension posts 7 are fixedly connected to the cantilever frame 4 .
[0058] In one embodiment, the driver includes a speed regulating motor 8, which is fixedly mounted on the cantilever frame 4. A first magnetic disk 9 is fixedly mounted on the output end of the speed regulating motor 8, and a second magnetic disk 11 is fixedly mounted on the top of the rotating shaft 10. The first magnetic disk 9 and the second magnetic disk 11 are magnetically coupled.
[0059] In one embodiment, a shaft seat 12 is fixedly connected to the inner side of the cover body 6 , the rotating shaft 10 is rotatably connected to the shaft seat 12 via a bearing, and the rotating shaft 10 is installed by using the shaft seat 12 .
[0060] In one embodiment, a limiting ring 13 is fixedly installed on the rotating shaft 10 and located above the sliding connection seat 16 , and an anti-collision ring 14 is fixedly installed on the bottom surface of the limiting ring 13 . The anti-collision ring 14 is an elastic buffer.
[0061] The function of the limiting ring 13 is to limit the distance that the sliding connection seat 16 slides upward. Generally, when the short rod is in a horizontal state, the sliding connection seat 16 is no longer allowed to slide upward. The anti-collision ring 14 is used to protect the limiting ring 13 and the sliding connection seat 16 to avoid strong collision between the limiting ring 13 and the sliding connection seat 16.
[0062] In one embodiment, a counterweight plate 17 is fixedly connected to the bottom of the sliding connection seat 16. In some cases, the weight of the sliding connection seat 16 cannot shrink the regular tripod 15 and the inverted tripod 20. Adding a counterweight plate 17 can shrink the regular tripod 15 and the inverted tripod 20. The impact is that a higher rotation speed is required to expand the regular tripod 15 and the inverted tripod 20. The counterweight plate 17 of appropriate weight is designed according to the type (viscosity) of the mixed liquid and the stirring speed experiment.
[0063] In one embodiment, the bottom end of the rotating shaft 10 has a hexagonal shaft section, the bottom end of the hexagonal shaft section has a threaded section, the fixed connection seat 18 is sleeved on the hexagonal shaft section, and the fixed connection seat 18 is squeezed upward and fixed by a nut 19 threadedly installed on the threaded section.
[0064] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
