Description
Technical Field
[0001] This utility model relates to the field of solvent mixing technology, specifically an organic solvent mixing device for tea pigment extraction. Background Technology
[0002] Tea pigments are a class of water-soluble pigments extracted from tea leaves. Their main components include thearubigins, theaflavins, and theabrownins. Thearubigins are brownish-red, theaflavins are orange-yellow, and theabrownins are dark brown; together they give tea pigments their complex and diverse colors.
[0003] Solvent mixing devices mainly consist of a container, stirring components, and a feeding and discharging system. The container holds the solvent, and the stirring components (such as stirring paddles, magnetic stir bar, etc.) bring different solvents into contact and mix within the container through rotation or other means.
[0004] When stirring solvents, the solvent is usually poured directly into a container and stirred using a mixing device. However, during use and observation, it has been found that the mixing device is usually fixed in position when stirring the solvent, resulting in a limited mixing range and making it difficult for the solvent to be fully mixed inside the container.
[0005] Therefore, an organic solvent mixing device for tea pigment extraction is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An organic solvent mixing device for tea pigment extraction, as described in this utility model, includes a mixing tank with an inlet at the top; a support frame is fixedly connected to the top of the mixing tank; a cylinder is fixedly connected to the top of the support frame; a push rod is fixedly connected to the output end of the cylinder; the push rod is slidably connected through the support frame; a fixing plate is fixedly connected to the end of the push rod; a motor is fixedly connected to the surface of the fixing plate; a first round rod is fixedly connected to the output end of the motor; the first round rod is rotatably connected through the motor. The first round rod is slidably connected to the mixing tank; the first round rod and the mixing tank are rotatably connected; a spiral blade is fixed to the outer wall of the first round rod; by making the spiral blade mix the solvent, the movement range of the solvent inside the mixing tank can be increased. Since the spiral blade will gradually move the solvent upward after contacting the solvent, the solvent at the bottom will be moved upward and the solvent at the top will gradually fall, thereby layering the solvent. At the same time, the cylinder can adjust the height of the spiral blade, so that it moves while the spiral blade is rotating, which will greatly agitate the solvent, thereby increasing the solvent mixing effect.
[0008] Preferably, a second round rod is rotatably connected to the middle of the mixing tank; a plurality of rotating blades are fixedly connected to the middle of the second round rod; by adding rotating blades, the vortex generated when the rotating blades rotate at high speed can be used to attract particles to the middle and then contact the rotating blades, thereby crushing the particles and increasing the solvent mixing effect. At the same time, the vortex generated when the rotating blades rotate will cause the solvent to come into contact with each other, increasing the solvent flow rate and thus increasing the contact area.
[0009] Preferably, a flow divider is fixedly connected to the inner wall of the feed inlet; a pair of baffles are fixedly connected inside the feed inlet; the baffles are located below the flow divider; multiple heating rods are fixedly connected inside both the flow divider and the baffles; by adding the flow divider, the solvent is first diverted, which also increases the contact area between the flow divider and the solvent. Subsequently, the solvent will be heated again after contacting the baffles. The solvent is also heated while the baffles slow down the movement speed of the solvent.
[0010] Preferably, the bottom of the flow divider plate has multiple round holes; the side wall of the feed inlet is connected to a gas guide pipe; the gas guide pipe and the flow divider plate are connected; the inside of the mixing tank can be heated through its round holes, thereby increasing the temperature inside the mixing tank, and at the same time the hot air will come into contact with the solvent, thereby increasing the fluidity of the solvent, thus increasing the effect of solvent mixing.
[0011] Preferably, a filter plate is provided in the middle of the feed inlet; a support plate is fixed to the end of the filter plate; the support plate and the end of the feed inlet are in contact; by adding a filter plate, the solvent can be filtered when it enters, and the support plate will be locked at the end of the feed inlet to provide support for the filter plate, thereby increasing the stability of the filter plate.
[0012] Preferably, a rubber pad is fixed to the outer wall of the feed inlet; the rubber pad and the support plate are correspondingly arranged; by adding the rubber pad, the support plate can provide more stable support for the filter plate, and the rubber pad is flexible and will deform according to the force it is subjected to, thereby automatically adjusting its shape.
[0013] The advantages of this utility model are:
[0014] 1. The organic solvent mixing device for tea pigment extraction described in this utility model increases the movement range of the solvent inside the mixing tank by mixing the solvent with a spiral blade. As the spiral blade gradually moves the solvent upward after contacting it, the solvent at the bottom moves upward and the solvent at the top gradually descends, thus layering the solvent. At the same time, the cylinder can adjust the height of the spiral blade, so that the spiral blade moves as it rotates, which will greatly agitate the solvent, thereby increasing the solvent mixing effect.
[0015] 2. The organic solvent mixing device for tea pigment extraction described in this utility model can attract particles to the center by adding a rotating blade. The vortex generated when the rotating blade rotates at high speed will then contact the rotating blade, thereby crushing the particles and increasing the solvent mixing effect. At the same time, the vortex generated when the rotating blade rotates will increase the solvent flow rate and thus increase the contact area. Attached Figure Description

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, an organic solvent mixing device for tea pigment extraction includes a mixing tank 1, with an inlet 11 at the top; a support frame 12 is fixedly connected to the top of the mixing tank 1; a cylinder 13 is fixedly connected to the top of the support frame 12; a push rod 14 is fixedly connected to the output end of the cylinder 13; the push rod 14 is slidably connected through the support frame 12; a fixing plate 15 is fixedly connected to the end of the push rod 14; a motor 16 is fixedly connected to the surface of the fixing plate 15; and a first round rod 17 is fixedly connected to the output end of the motor 16. The first round rod 17 is through-mounted and rotatably connected to the motor 16; the first round rod 17 is slidably connected to the mixing tank 1; the first round rod 17 and the mixing tank 1 are rotatably connected; a spiral blade 18 is fixedly attached to the outer wall of the first round rod 17; during operation, the solvent is first poured into the mixing tank 1 through the feed port 11. After the solvent enters the tank, the motor 16 is started to rotate the first round rod 17. When the first round rod 17 rotates, it drives the spiral blade 18 to rotate. When the spiral blade 18 rotates, it agitates the solvent. The solvent moves upward along the surface of the spiral blade 18. After the spiral blade 18 stirs in the same position for a period of time, the cylinder 13 is activated. At this time, the push rod 14 moves, pushing the fixed plate 15 to move. When the fixed plate 15 moves, it adjusts the height of the first circular rod 17. Since the spiral blade 18 is rotating, when the spiral blade 18 moves, it will drive the solvent inside the mixing tank 1, thereby greatly agitating the solvent and increasing the contact area between the spiral blade 18 and the solvent. The cylinder 13 moves the spiral blade 18. After adjustment, the spiral blade 18 will come into contact with more solvent, thereby agitating and mixing it. By mixing the solvent with the spiral blade 18, the movement of the solvent inside the mixing tank 1 can be increased. As the spiral blade 18 gradually moves the solvent upward after contacting it, the solvent at the bottom moves upward and the solvent at the top gradually descends, thus layering the solvent. At the same time, the cylinder 13 can adjust the height of the spiral blade 18, so that it moves as the spiral blade 18 rotates, which will greatly agitate the solvent, thereby increasing the solvent mixing effect.
[0026] like Figure 3As shown, a second round rod 2 is rotatably connected to the middle of the mixing tank 1; multiple rotating blades 21 are fixedly connected to the middle of the second round rod 2; during operation, when the solvent is poured into the mixing tank 1, it will first come into contact with the rotating blades 21. At this time, the rotating blades 21 will rotate rapidly in the solvent, thereby forming a water vortex. At this time, the particles in the solvent will gradually move towards the middle of the mixing tank 1, and then gradually come into contact with the rotating blades 21 by the attraction of the vortex. At this time, the high-speed rotating blades 21 will crush these particles. After the particles are crushed, they will come into full contact with the solvent. By adding rotating blades 21, the vortex generated by the high-speed rotation of the rotating blades 21 can be used to attract the particles to the middle and then contact the rotating blades 21, thereby crushing the particles and increasing the solvent mixing effect. At the same time, the vortex generated by the rotation of the rotating blades 21 will cause the solvent to come into contact with each other, increasing the solvent flow rate and thus increasing the contact area.
[0027] like Figure 4 As shown, a flow divider plate 3 is fixedly connected to the inner wall of the feed inlet 11; a pair of baffles 31 are fixedly connected inside the feed inlet 11; the baffles 31 are located below the flow divider plate 3; multiple heating rods 32 are fixedly connected inside both the flow divider plate 3 and the baffles 31; during operation, before the solvent is poured into the mixing tank 1 through the feed inlet 11, the heating rods 32 are turned on to generate heat. When the solvent enters the feed inlet 11, it will first come into contact with the feed inlet 11. At this time, the solvent will be diverted by the feed inlet 11, and at the same time, the heat generated by the heating rods 32 will be transferred to the solvent through the flow divider plate 3. The solvent then flows into the baffle 31. Due to the inclination of the baffle 31 surface, the solvent's movement speed is slowed upon contact, and it also flows into the mixing tank 1. At the same time, the heat generated by the heating rod 32 is also transferred to the solvent through the baffle 31. By adding the diverting plate 3 to first divert the solvent, the contact area between the diverting plate 3 and the solvent is increased. Subsequently, the solvent is heated again after contacting the baffle 31. The baffle 31 slows down the movement speed of the solvent while also heating it.
[0028] like Figure 4As shown, the bottom of the flow divider 3 has multiple circular holes 4; the side wall of the feed inlet 11 is connected to a gas guide pipe 41; the gas guide pipe 41 and the flow divider 3 are connected; during operation, the gas guide pipe 41 is first connected to an air pump, and then the gas is transmitted to the interior of the flow divider 3 through the gas guide pipe 41. When the gas enters the interior of the flow divider 3, it will come into contact with the heating rod 32, thereby acquiring heat energy and becoming hot gas. Subsequently, it will move into the interior of the mixing tank 1 through the circular holes 4. When the solvent comes into contact with the baffle 31, the hot gas flowing out of the circular holes 4 will also come into contact with the solvent, thereby assisting the baffle 31 in heating the solvent; the interior of the mixing tank 1 can be heated through its own circular holes 4, thereby increasing the temperature inside the mixing tank 1. At the same time, the hot gas will come into contact with the solvent, thereby increasing the fluidity of the solvent, thus increasing the effect of solvent mixing.
[0029] like Figure 5 As shown, a filter plate 5 is provided in the middle of the feed inlet 11; a support plate 51 is fixedly connected to the end of the filter plate 5; the support plate 51 and the end of the feed inlet 11 are in contact; during operation, before pouring the solvent into the feed inlet 11, the filter plate 5 is placed inside the feed inlet 11. After the filter plate 5 is placed, the end of the support plate 51 will be locked in the end of the feed inlet 11, thereby fixing the filter plate 5. When the solvent enters the feed inlet 11, it will come into contact with the filter plate 5. At this time, the filter plate 5 will filter the impurities inside the solvent. By adding the filter plate 5, the solvent can be filtered when it enters. At the same time, the support plate 51 will be locked in the end of the feed inlet 11 to provide support for the filter plate 5, thereby increasing the stability of the filter plate 5.
[0030] like Figure 5 As shown, a rubber pad 6 is fixed to the outer wall of the feed inlet 11; the rubber pad 6 and the support plate 51 are correspondingly arranged; during operation, when the support plate 51 is stuck at the end of the feed inlet 11, it will contact the rubber pad 6. At this time, the rubber pad 6 will fill the gap between the support plate 51 and the rubber pad 6, thereby increasing the contact between the support plate 51 and the feed inlet 11; by adding the rubber pad 6, the support plate 51 can provide more stable support for the filter plate 5. At the same time, the rubber pad 6 is flexible and will deform according to the force it is subjected to, thereby automatically adjusting its shape.
[0031] Working principle: Solvent is first poured into the mixing tank 1 through the feed inlet 11. After the solvent enters, the motor 16 is started, causing the first circular rod 17 to rotate. When the first circular rod 17 rotates, it drives the spiral blade 18 to rotate. When the spiral blade 18 rotates, it agitates the solvent, and the solvent below moves upward along the surface of the spiral blade 18. After the spiral blade 18 agitates in the same position for a period of time, the cylinder 13 is started. At this time, the push rod 14 moves. When the push rod 14 moves, it pushes the fixed plate 15 to move. When the fixed plate 15 moves, it adjusts the height of the first circular rod 17. Since the spiral blade 18 is rotating, when the spiral blade 18 moves, it agitates the solvent inside the mixing tank 1. The solvent is agitated, increasing the contact area between the spiral blade 18 and the solvent. After the cylinder 13 adjusts the spiral blade 18, it will come into contact with more solvent, thus agitating and mixing it. When the solvent is poured into the mixing tank 1, it first comes into contact with the rotating blade 21. At this time, the rotating blade 21 rotates rapidly in the solvent, forming a vortex. The particles in the solvent gradually move towards the center of the mixing tank 1, and then gradually come into contact with the rotating blade 21 by the attraction of the vortex. The high-speed rotating blade 21 will then crush these particles, and after the particles are crushed, they will come into full contact with the solvent. Before the solvent is poured into the mixing tank 1 through the feed inlet 11, When the heating rod 32 is turned on to generate heat, the solvent enters the inlet 11 and first contacts it. The solvent is then diverted by the inlet 11, and the heat generated by the heating rod 32 is transferred to the solvent through the diversion plate 3. The diverted solvent then contacts the baffle 31. Due to the inclined surface of the baffle 31, the solvent's movement is slowed upon contact, and it flows further into the mixing tank 1. The heat generated by the heating rod 32 is also transferred to the solvent through the baffle 31. The gas is then connected to the air pump via the gas pipe 41 and transmitted to the diversion plate 3. Upon entering the diversion plate 3, the gas contacts the heating rod 32, thus absorbing heat and becoming hot gas. The solvent then moves into the mixing tank 1 through the round hole 4. When the solvent comes into contact with the baffle 31, the hot air flowing out of the round hole 4 also comes into contact with the solvent, thus assisting the baffle 31 in heating the solvent. Before pouring the solvent into the feed inlet 11, the filter plate 5 is placed inside the feed inlet 11. After the filter plate 5 is placed, the end of the support plate 51 will be stuck at the end of the feed inlet 11, thus fixing the filter plate 5. When the solvent enters the feed inlet 11, it will come into contact with the filter plate 5. At this time, the filter plate 5 will filter the impurities inside the solvent. When the support plate 51 is stuck at the end of the feed inlet 11, it will come into contact with the rubber pad 6. At this time, the rubber pad 6 will fill the gap between the support plate 51 and the rubber pad 6, thereby increasing the contact between the support plate 51 and the feed inlet 11.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
