Description

Technical Field

[0001] This utility model belongs to the field of mixing device technology, and specifically relates to a novel mixing device. Background Technology

[0002] Microbial fuel cells are an environmentally friendly new bioenergy technology for water treatment. This technology can use microorganisms as catalysts to degrade organic pollutants in wastewater and convert the chemical energy of the pollutants into electrical energy. It is expected to enable wastewater treatment plants to achieve self-sufficiency in electricity and open up a new path in wastewater treatment.

[0003] When preparing microbial fuel cells or their anodes, multiple chemical substances need to be used in combination and reaction to obtain them. In this process, the chemical substances need to be proportioned and put into a mixing container, and a solution is formed by adding the corresponding solvent. Then, the mixture is stirred to obtain the reaction products.

[0004] However, during this process, when multiple chemical substances are stirred and mixed, foam is easily formed due to the incorporation of air during the stirring of the solution. As the foam is generated and accumulates, a large amount of foam will gather on the liquid surface, which will affect the mixing process. For example, foam is formed by gas in liquid, which will affect the fluidity, viscosity and stability of the mixture. Moreover, foam is a poor conductor of heat, and its presence will significantly affect the heat transfer process. Therefore, when mixing under water bath heating, the presence of foam will cause deviations in temperature conduction, resulting in temperature differences in the mixed solution. Furthermore, the formation of foam may affect the uniformity of the mixture during the mixing process. Summary of the Invention

[0005] Based on this, this application provides a novel mixing device to solve the technical problem in the prior art where foam generated during the agitation process gathers on the liquid surface, affecting the mixing effect.

[0035] Please refer to Figures 1 to 8 In one specific embodiment of this application,

[0036] A novel mixing device includes:

[0037] Insulation components are used for water bath heating of the mixing container;

[0038] A suspension assembly, which is detachably connected to the insulation assembly and is equipped with a power unit;

[0039] A stirring component is provided on the suspension component, and the power unit drives the stirring component to rotate to stir the mixture inside the mixing container;

[0040] A shielding component is disposed on the agitating component and can extend and retract with the agitating component to cover the surface of the mixture inside the mixing container.

[0041] The insulation component can be a pool or a box; the suspension component can be a hook or a device for suspending objects; the stirring component is a stirring shaft for stirring the mixture or a device for stirring the mixture; the shielding component can be a lid or a board or an object that can cover objects.

[0042] During operation, the mixing container is placed in the insulation component, and the raw materials to be mixed are put into the mixing container. Then, the suspension component is moved so that it drives the stirring component to align with and enter the mixing container. The position of the suspension component is then fixed so that the stirring component extends into the mixture. At the same time, the stirring component will drive the shielding component into the mixing container to cover the surface of the mixture.

[0043] Taking the preparation process of a biofuel cell as an example, when preparing the anode of a biofuel cell, it is necessary to mix multiple compounds. The specific process is as follows:

[0044] 50°C water is introduced into the insulation component. Then, FeSO4·7H2O and hexadecyltrimethylammonium bromide (CTAB) are weighed into a three-necked flask (mixing container). The three-necked flask is placed in the insulation component for water bath heating. Distilled water is added to dissolve the flask, and glycerol is added dropwise to obtain a mixture. The mixture then needs to be stirred. The stirring component is mounted on the suspension component, and the suspension component is moved to align the stirring component with the three-necked flask. The suspension component is then lowered to bring the stirring component into the three-necked flask. At the same time, the shielding component enters the three-necked flask along with the stirring component and covers the surface of the mixture. The stirring component is now in the mixture. The stirring component is rotated by the power unit to stir the mixture for 30 minutes. During stirring, the shielding component covers the surface of the mixture to reduce foam generated by stirring and to prevent excessive foam accumulation. After stirring, a homogeneous mixture is obtained.

[0045] By means of the above method, the air between the surface of the mixture and the shielding component can be reduced during the preparation process, thereby reducing the air content on the surface of the mixture. This reduces the amount of air entering the mixture during stirring, thus reducing the amount of foam formed due to air entering the mixture. At the same time, the shielding component can also block the foam generated during stirring and allow it to dissipate in time, reducing the amount of foam that accumulates on the surface of the mixture, thereby avoiding a large amount of foam accumulating on the surface of the mixture and reducing the impact of foam on the mixture.

[0046] Furthermore, the shielding component can also prevent splashes generated during stirring from flying out of the three-necked flask when covering the surface of the mixture, thus eliminating the waste of raw materials.

[0047] Specifically, an embodiment of the insulation component in the above process is provided:

[0048] The insulation component includes a box 301 with an open top, a ring frame 304 for supporting the mixing container is provided inside the box 301, and at least one support column 302 for connecting the suspension component is formed at the upper end of the box 301.

[0049] 50°C hot water is introduced into the chamber 301, and then the three-necked flask is placed on the ring frame 304 so that the three-necked flask is in contact with the 50°C hot water. Then the stirring component is inserted into the three-necked flask and placed on the support 302 to complete the installation.

[0050] The above process enables the rapid setup and water bath heating of a three-necked flask (mixing vessel).

[0051] Furthermore, in the actual preparation process, when a stirring component is used to agitate the mixture, the flow of the mixture can cause the three-necked flask to shake, leading to instability. Therefore,

[0052] In this application, an air cushion 303 is provided on the inner wall of the open upper part of the box 301, and an air valve for inflating and deflating the air cushion 303 is connected to the air cushion 303.

[0053] In the specific preparation process, after the three-necked flask passes through the open part of the upper end of the box 301 and is placed on the ring frame 304, air is injected into the air cushion 303 through the air valve, causing the volume of the air cushion 303 to expand, thereby filling the gap between the open part of the upper end of the box 301 and the outer wall of the three-necked flask, thus using the air cushion 303 to tightly wrap the three-necked flask.

[0054] Through the above process, the three-necked flask can be stably supported, and when the air cushion 303 comes into contact with the three-necked flask, the air cushion 303 will tend to extend downward at the contact position due to elastic deformation. Due to the downward force generated by the air cushion 303 on the outer wall of the three-necked flask, the three-necked flask is stably supported on the ring frame 304, thereby improving the stability of the three-necked flask.

[0055] Specifically, an embodiment of the suspension assembly in the above process is provided:

[0056] The suspension assembly includes a crossbeam 101, which is detachably connected to the support column 302. A cylinder 102 is provided on the crossbeam 101, and a cylinder rod 103 that can extend and retract vertically within the cylinder 102 is provided in the cylinder 102. The agitation assembly is connected to the cylinder rod 103.

[0057] During operation, the crossbeam 101 is first moved to set up the equipment. The crossbeam 101 is then used to drive the stirring component into the three-necked flask. The crossbeam 101 is then connected to the support column 302 with bolts (the bolts are connected to the crossbeam 101, and the upper end of the support column 302 has a threaded hole), thereby suspending the stirring component. When fixing the crossbeam 101, the bolts are rotated to fix the position between the crossbeam 101 and the bolts. The height between the crossbeam 101 and the support column 302 is then adjusted. When the bolts are screwed in, the depth of the bolts into the threaded hole at the upper end of the support column 302 is used to adjust the height of the stirring component in the three-necked flask, so that the stirring component is located in the mixture.

[0058] Through the above process, the height of the stirring component can be adjusted, allowing the stirring component to extend into the mixture at different depths, thus achieving different depths of stirring in the mixture in the three-necked flask.

[0059] Specifically, an embodiment of the power unit in the above process is provided:

[0060] The power unit includes a rotating sleeve 104 rotatably connected to a crossbeam 101. A gear ring 105 is connected to the outer wall of the rotating sleeve 104. A gear 106 that meshes with the gear ring 105 is connected to the crossbeam 101. The gear 106 is driven by a motor. The rotating sleeve 104 drives the agitator to rotate.

[0061] During preparation, the motor is powered on and controlled to turn on and off. When the power is turned on, the gear 106 is rotated. The gear 106 meshes with the gear ring 105 to rotate the rotating sleeve 104. The rotating sleeve 104 rotates along the axis of the three-necked flask, thereby driving the stirring component to rotate horizontally, thus agitating the mixture.

[0062] The above method enables automatic stirring after the stirring component is inserted into the mixture. The stirring time and speed of the stirring component can be controlled by a motor, thereby making the stirring process more stable.

[0063] Specifically, an embodiment of the agitation component in the above process is provided:

[0064] The stirring assembly includes a slide rod 201 that rotates at the lower end of the cylinder rod 103, and the slide rod 201 slides in contact with the rotating sleeve 104. A rotating rod 202 is fixed at the lower end of the slide rod 201, and a plurality of stirring rods 207 are hinged to the lower end of the rotating rod 202.

[0065] As the cylinder rod 103 lowers the slide rod 201, the slide rod 201 slides downward within the rotating sleeve 104. This causes the slide rod 201 to move the multiple stirring rods 207 at the lower end of the rotating rod 202 downward. During this process, the multiple stirring rods 207 can be blocked by hand or the mouth of the three-necked flask, causing them to move closer to the rotating rod 202 and shrink their horizontally occupied area. After the multiple stirring rods 207 enter the interior of the three-necked flask, the rotation of the rotating sleeve 104 can drive the slide rod 201 to rotate. Figure 4 and Figure 5As can be seen, the structure of the slide rod 201 is not circular, and the rotating sleeve 104 is matched with the slide rod 201. That is, when the rotating sleeve 104 rotates, the slide rod 201 will rotate accordingly. For another example, if the slide rod 201 has a rectangular structure, then the inner wall of the rotating sleeve 104 is also rectangular and slides in contact with the outer wall of the slide rod 201, ensuring that the rotating sleeve 104 can drive the slide rod 201 to rotate. This generates centrifugal force when the slide rod 201 drives the rotating rod 202 to rotate, causing multiple stirring rods 207 to rotate and unfold in the vertical direction and rotate in the horizontal direction along the axis of the rotating rod 202 to stir the mixture.

[0066] Through the above process, multiple stirring rods 207 can be rotated and retracted in the vertical direction relative to the rotating rod 202, changing the space occupied and allowing them to pass smoothly through a mixing container with a small opening and a large internal space. Taking a three-necked flask as an example, the inner diameter of the flask opening is small while the inner diameter of the flask body is large. Therefore, multiple stirring rods 207 can pass through the flask opening after being retracted, and unfold inside the flask body, increasing the contact area and range with the mixture and improving the stirring efficiency of the mixture.

[0067] In addition, after the rotating rod 202 stops rotating, the centrifugal force disappears. At this time, the stirring rod 207 rotates downward and retracts to avoid the stirring rod 207 spreading out and interfering with the bottle mouth when it is taken out.

[0068] Specifically, an embodiment is provided for the agitation component in the above process:

[0069] Preferably, the shielding assembly includes a fixed ring 206 formed in the middle of the rotating rod 202, an outer ring 208 rotatably attached to the outside of the fixed ring 206, and a plurality of swing arms 204 hinged to the side of the outer ring 208. An extendable accordion cover 205 is provided between each two adjacent swing arms 204. A torsion spring is provided at the rotatable connection between the swing arm 204 and the fixed ring 206 to drive the swing arm 204 to rotate upward and approach the rotating rod 202.

[0070] As the rotating rod 202 descends into the three-necked flask, the fixed ring 206 drives the outer ring 208 to descend, causing the outer ring 208 to drive multiple swing arms 204 into the three-necked flask. At this time, the torsion spring drives the multiple swing arms 204 to move upward and close to the rotating rod 202, thus folding the bellows cover 205 and causing it to retract. After entering the flask, the multiple swing arms 204 will rotate downward and open due to the centrifugal force generated by the rotation of the rotating rod 202, and the torsion spring will undergo elastic deformation to store force. When the multiple swing arms 204 rotate and open, the centrifugal force overcomes the force of the torsion spring, causing the multiple swing arms 204 to rotate to a horizontal state, while the torsion spring remains in a stored state. During this process, the multiple swing arms 204 can unfold the bellows cover 205 to cover the surface of the mixture. When the rotating rod 202 rotates, the rotating rod 202 will drive the fixed ring 206 to rotate, but the outer ring 208 will not rotate.

[0071] Through the above process, the accordion cover 205 can be used to cover the mixture during the stirring process, so as to avoid the foam generated by stirring from accumulating on the surface of the mixture and affecting the preparation process.

[0072] Similarly, after the preparation is completed, as the rotation of the rotating rod 202 stops, the centrifugal force gradually decreases. When the force of the torsion spring is greater than the centrifugal force, the torsion spring in the stored state will drive the swing arm 204 to rotate upward and retract towards the rotating rod 202, thereby reducing the volume and making it easier to remove from the three-necked flask.

[0073] In addition, if the fixed ring 206 comes into direct contact with the outer ring 208 and undergoes hard friction, it will cause wear and lead to a larger gap. This may cause the outer ring 208 and the fixed ring 206 to collide due to shaking, which may result in damage.

[0074] Therefore, a bearing is provided between the fixed ring 206 and the outer ring 208, with the inner ring of the bearing connected to the fixed ring 206 and the outer ring of the bearing connected to the outer ring 208.

[0075] By using a bearing as a transition element, the fixed ring 206 and the outer ring 208 are no longer in direct contact. Instead, the bearing adds a rotation link, making the rotation between the fixed ring 206 and the outer ring 208 smoother and more stable.

[0076] Furthermore, directly utilizing the centrifugal force generated by the rotation of the rotating rod 202 to unfold multiple swing arms 204 can be problematic due to variations in the rotational speed of the rotating rod 202 during the initial and final stages. For example, if the rotating rod 202 initially accelerates gradually, increasing its speed from slow to fast, the centrifugal force will gradually increase until it is sufficient to overcome the torsion spring force and cause the swing arms 204 to rotate and unfold. This can result in the accordion cover 205 not unfolding in a timely manner.

[0077] Therefore, preferably, the suspension assembly further includes a vertical rod 110 fixed to the lower end of the crossbeam 101, a middle ring 107 is provided at the lower end of the vertical rod 110, the rotating rod 202 passes through the middle ring 107, the middle ring 107 is located above the fixed ring 206, and the shielding assembly further includes a plurality of connecting rods 203 hinged to the outside of the middle ring 107, and the other ends of the plurality of connecting rods 203 are respectively hinged to the inside of a plurality of swing arms 204.

[0078] When the suspension assembly enters the three-necked flask, the cylinder rod 103 drives the slide rod 201 to move upward, causing the rotating rod 202 to rise, which in turn drives the fixed ring 206 to rise, reducing the distance between the fixed ring 206 and the middle ring 107. The multiple connecting rods 203 are located below the middle ring 107 and can rotate. When the swing arm 204 rises along with the outer ring 208 and is driven by the fixed ring 206, the inner side of the swing arm 204 is supported by the connecting rods 203. Thus, the multiple swing arms 204 rotate outward and downward in the vertical direction under the support of the multiple connecting rods 203 from the inside. In this way, the cylinder rod 103 drives the slide rod 201 to move up and down, thereby realizing the expansion and contraction of the multiple swing arms 204.

[0079] In this way, it is no longer necessary to rely on the rotation of the rotating rod 202 to generate centrifugal force to unfold the multiple swing arms 204. Instead, they can unfold actively without rotation, so that the bellows cover 205 can cover the surface of the mixture. This avoids the problem that the centrifugal force generated by the initial rotation speed of the rotating rod 202 is insufficient and the multiple swing arms 204 cannot unfold smoothly.

[0080] In addition, in order to improve the stability between the crossbeam 101 and the three-necked flask, in this application, a conical plug 109 with a conical structure is provided at the middle of the lower end of the crossbeam 101, and the conical plug 109 can contact the opening of the mixing container.

[0081] When the crossbeam 101 is mounted on the three-necked flask, the conical stopper 109 is inserted into the mouth of the three-necked flask, thereby filling the gap between the mouth of the flask and the crossbeam 101, and further supporting the stability of the crossbeam 101 by using the mouth of the flask, thus improving the stability of the crossbeam 101.

[0082] Here, we take the use of a three-necked flask in the preparation of biofuel cells as an example:

[0083] First, 50°C hot water is introduced into the chamber 301. Then, the three-necked flask is placed on the ring frame 304 so that the three-necked flask is in contact with the 50°C hot water. Air is introduced into the air cushion 303 through the air valve, causing the air cushion 303 to expand. This causes the air cushion 303 to fill the gap between the upper opening of the chamber 301 and the outer wall of the three-necked flask, thus tightly wrapping the three-necked flask with the air cushion 303. Then, the raw materials to be mixed are put into the three-necked flask, and the crossbeam 101 is moved to set up. The crossbeam 101 drives the stirring component to extend into the three-necked flask. Then, the crossbeam 101 is connected to the support column 302 with bolts.

[0084] Then, as the rotating rod 202 descends into the three-necked flask, the fixing ring 206 drives the outer ring 208 to descend. During this process, multiple stirring rods 207 can be blocked by hand or the mouth of the three-necked flask, causing the stirring rods 207 to move closer to the rotating rod 202, reducing their horizontal area and allowing them to enter the three-necked flask. Simultaneously, the outer ring 208 drives multiple swing arms 204 into the three-necked flask. At this time, the torsion spring causes the swing arms 204 to move upward and retract towards the rotating rod 202, and the accordion cover 205 is in a folded state. After entering the flask body... The cylinder rod 103 drives the slide rod 201 to move upward, causing the rotating rod 202 to rise, which in turn drives the fixed ring 206 to rise, reducing the distance between the fixed ring 206 and the middle ring 107. The multiple connecting rods 203 are located below the middle ring 107 and can rotate. When the swing arm 204 rises along with the outer ring 208 and is driven by the fixed ring 206, the inner side of the swing arm 204 is supported by the connecting rods 203. Thus, the multiple swing arms 204, supported from the inside by the multiple connecting rods 203, rotate outward and downward in the vertical direction, thereby completing the unfolding of the bellows cover 205 and covering the surface of the mixture.

[0085] Next, the motor is connected to the power supply and the start and stop are controlled. When the power is turned on, the gear 106 is driven to rotate. The gear 106 meshes with the gear ring 105 to drive the rotating sleeve 104 to rotate. The rotating sleeve 104 rotates along the axis of the three-necked flask. The rotating sleeve 104 drives the slide rod 201 and the rotating rod 202 to rotate horizontally. The centrifugal force generated by the rotating rod 202 causes multiple stirring rods 207 to rotate and unfold in the vertical direction, and rotate in the horizontal direction along the axis of the rotating rod 202 to stir the mixture until it is completely mixed.

[0086] Finally, turn off the motor to stop the rotating sleeve 104 from rotating. As the rotating rod 202 stops rotating, the centrifugal force gradually decreases. When the force of the torsion spring is greater than the centrifugal force, the torsion spring in the stored state will drive the swing arm 204 to rotate upward and retract towards the rotating rod 202. At the same time, the multiple stirring rods 207 will not be affected by the centrifugal force and will automatically hang down due to their own weight, completing the process of rotating downward and moving closer to each other, thereby reducing the volume and making it easier to remove from the three-necked flask. Remove the bolts, lift the crossbeam 101 upward, and move the rotating rod 202 and multiple stirring rods 207 out of the mixing container.

[0087] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
