Description
Technical Field
[0001] This utility model relates to a fluid stirrer and stirring device, belonging to the technical field of stirring devices. Background Technology
[0002] In the field of fluid mixing technology, agitators are key equipment for mixing and homogenizing different fluids, and are widely used in industries such as chemical, food, and pharmaceutical. Traditional fluid mixing devices typically consist of a mixing container, a stirring shaft, and stirring blades. Their working principle is that the stirring shaft drives the blades to rotate, causing the fluid in the container to undergo convection, shearing, or diffusion motion, thereby achieving the purpose of mixing.
[0003] However, traditional mixing devices lack sampling structures during operation, making it impossible to obtain fluid samples at any time. This makes it difficult to monitor the mixing effect or reaction status in real time, and operators cannot accurately judge whether the current mixing has achieved the expected effect, which may lead to a reduction in the quality of fluid mixing. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a fluid stirrer and stirring device, which solves the problem that in the prior art, when the mixing device lacks a sampling structure during operation, it is impossible to obtain fluid samples at any time, making it difficult to grasp the stirring effect or reaction status in real time, and operators cannot accurately judge whether the current stirring has achieved the expected effect, resulting in a reduction in the quality of fluid mixing.
[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: A fluid stirrer and stirring device, including a mixing tank, which is a hollow structure. A feed pipe communicating with the hollow structure is fixedly installed on the mixing tank. A rotating shaft is rotatably installed on the mixing tank. One end of the rotating shaft extends to the outside of the mixing tank and a turntable is fixedly installed thereon. The other end of the rotating shaft extends into the interior of the hollow structure and a plurality of stirring rods are fixedly installed thereon. A sampling groove is opened on one side of the rotating shaft inside the hollow structure. A sealing structure for closing the sampling groove is opened on the rotating shaft. A threaded hole communicating with the sampling groove is opened on the rotating shaft. A moving rod is threaded inside the threaded hole. A sampling structure for extracting samples from the sampling groove is installed on the moving rod. A one-way valve communicating with the sampling groove is also installed on the rotating shaft.
[0006] By adopting the above technical solution, the fluid to be mixed is first introduced into the hollow structure through the feed pipe. Then, the turntable is rotated to drive the rotating shaft to rotate, which in turn drives the stirring rod to rotate, thus mixing the fluid. During the mixing process, the sealing structure is used to remove the seal on the sampling tank, and the mixed fluid enters the sampling tank. Then, the sample in the sampling tank is taken out through the sampling structure. This device can take samples during the mixing process and can obtain fluid samples at different mixing stages in real time, which is convenient for timely monitoring of the mixing state and effect of the fluid. In order to adjust the stirring process according to the sample conditions, the mixing quality can be improved.
[0007] The present invention is further configured such that: the sealing structure includes a sealing groove, a sealing plate and a push plate, the sealing groove is opened on the rotating shaft and communicates with the sampling groove, the sealing plate is slidably disposed inside the sealing groove, one end of the sealing plate can abut against the inner wall of the sampling groove, and the other end of the sealing plate extends to the outside of the rotating shaft and is fixedly disposed with the push plate.
[0008] The present invention is further configured such that: a positioning groove is provided on the inner wall of the sealing groove, a positioning plate is fixedly provided on the side of the sealing plate facing the positioning groove, the positioning plate is slidably connected to the positioning groove, and a first spring is fixedly provided between the side of the positioning plate away from the sliding surface and the inner wall of the positioning groove.
[0009] By adopting the above technical solution, pulling the push plate causes the sealing plate to slide in the sealing groove, moving the sealing plate away from the sampling groove. At the same time, when the sealing plate moves, it causes the positioning plate to slide in the positioning groove, compressing the first spring and thus canceling the seal on the sampling groove. After the sample enters the sampling groove, the push plate is released, and the first spring resets, pushing the positioning plate to slide in the positioning groove. This causes the positioning plate to move the sealing plate in the sealing groove towards the sampling groove, thus sealing the sampling groove.
[0010] The present invention is further configured such that: the sampling structure includes a sliding channel, a sampling tube, a sampling head, a push block, a guide channel, and an airbag. The sliding channel is opened on the moving rod, the push block is slidably disposed inside the sampling groove, the push block is rotatably connected to the moving rod, the guide channel is opened on the push block and communicates with the sliding channel and the sampling groove respectively, the sampling tube is slidably disposed inside the sliding channel, the sampling head is fixedly disposed and communicates with one end of the sampling tube, the sampling head can extend through the guide channel to the inside of the sampling groove, and the other end of the sampling tube extends to the outside of the moving rod and is fixedly disposed and communicates with the airbag.
[0011] The present invention is further configured such that: a limiting groove communicating with the guide groove is provided on the push block, a limiting block is slidably provided inside the limiting groove, one end of the limiting block can extend into the interior of the guide groove and abut against the inner wall of the guide groove, and a second spring is fixedly provided between the side of the limiting block located inside the limiting groove and the inner wall of the limiting groove.
[0012] By adopting the above technical solution, the sampling tube is inserted into the sliding groove, causing the sampling tube to move the sampling head towards the guide groove. When the sampling head comes into contact with the limiting block, the limiting block slides into the limiting groove under the action of contact, so that the limiting block is housed inside the limiting groove and separated from the guide groove. When the limiting block moves, it compresses the second spring, which cancels the seal on the guide groove. At this time, the sampling head moves through the guide groove to the inside of the sampling groove, and then the air bladder is squeezed. Through the elastic back suction of the air bladder, the sample is adsorbed into the inside of the sampling tube for sampling. Then the sampling tube is taken out for observation.
[0013] The present invention is further configured such that a turbulence block is fixedly provided at one end of the stirring rod away from the rotating shaft.
[0014] The present invention is further configured such that: the mixing tank is provided with a discharge port that communicates with the hollow structure.
[0015] The beneficial effects of this invention are as follows: First, the fluid to be mixed enters the hollow structure through the feed pipe. Then, the turntable is rotated to drive the rotating shaft to rotate, which in turn drives the stirring rod to rotate, thus mixing the fluid. During the mixing process, the sealing structure removes the seal on the sampling tank, and the mixed fluid enters the sampling tank. Then, the sample in the sampling tank is taken out through the sampling structure. This device can take samples during the mixing process and can obtain fluid samples at different mixing stages in real time, which is convenient for timely monitoring of the mixing state and effect of the fluid. This allows for adjustments to the stirring process based on the sample conditions, thereby improving the mixing quality. Attached Figure Description

Detailed Implementation
[0023] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0024] like Figures 1 to 3 As shown, a fluid agitator and agitation device include a mixing tank 1, which is fixed to an external support frame. The mixing tank 1 is fixedly supported by the external support frame. The mixing tank 1 is a hollow structure 2. A feed pipe 3 communicating with the hollow structure 2 is fixedly installed on the mixing tank 1. A rotating shaft 4 is rotatably installed on the mixing tank 1. One end of the rotating shaft 4 extends to the outside of the mixing tank 1 and a turntable 5 is fixedly installed thereon. The other end of the rotating shaft 4 extends into the interior of the hollow structure 2 and a plurality of stirring rods 6 are fixedly installed thereon. A sampling groove 7 is horizontally opened on one side of the rotating shaft 4 inside the hollow structure 2. A sealing structure for closing the sampling groove 7 is opened on the rotating shaft 4. A threaded hole 8 communicating with the sampling groove 7 is opened on the rotating shaft 4. A moving rod 9 is threaded inside the threaded hole 8. A sampling structure for extracting samples from the sampling groove 7 is provided on the moving rod 9. A one-way valve 10 communicating with the sampling groove 7 is also provided on the rotating shaft 4.
[0025] like Figure 3 and Figure 4As shown, the sealing structure includes a sealing groove 1011, a sealing plate 1012, and a push plate 1013. The sealing groove 1011 is vertically opened on the rotating shaft 4 and communicates with the sampling groove 7. The sealing plate 1012 is slidably disposed inside the sealing groove 1011. The sealing plate 1012 slides along the opening direction of the sealing groove 1011. One end of the sealing plate 1012 can abut against the inner wall of the sampling groove 7. When the sealing plate 1012 abuts against the sampling groove 7, the sampling groove 7 can be sealed. When the sealing plate 1012 is separated from the sampling groove 7, the sealing of the sampling groove 7 can be canceled. The other end of the sealing plate 1012 extends to the outside of the rotating shaft 4 and is fixedly disposed with the push plate 1013. A positioning groove 1021 is provided on the inner wall of the sealing groove 1011. The positioning groove 1021 is in the same direction as the sealing groove 1011. A positioning plate 1022 is fixedly provided on the side of the sealing plate 1012 facing the positioning groove 1021. The positioning plate 1022 is slidably connected to the positioning groove 1021. A first spring 1023 is fixedly provided between the side of the positioning plate 1022 away from the sliding surface and the inner wall of the positioning groove 1021. When the first spring 1023 is not under force, it is in a tensioned state. At this time, the sealing plate 1012 and the sampling groove 7 are in an abutting state.
[0026] like Figure 5 and Figure 6 As shown, the sampling structure includes a sliding channel 1031, a sampling tube 1032, a sampling head 1033, a pusher block 1034, a guide channel 1035, and an airbag 1036. The sliding channel 1031 is vertically formed on the moving rod 9. The pusher block 1034 is slidably disposed inside the sampling groove 7, and slides in contact with the sampling groove 7. The pusher block 1034 is rotatably connected to one end of the moving rod 9, and the end of the moving rod 9 away from the pusher block 1034 extends to the outside of the rotating shaft 4. On the side, the guide groove 1035 is opened on the push block 1034 and is connected to the sliding through groove 1031 and the sampling groove 7 respectively. The sampling tube 1032 is slidably disposed inside the sliding through groove 1031. The sampling head 1033 is fixedly disposed in connection with one end of the sampling tube 1032. The sampling head 1033 can extend through the guide groove 1035 to the inside of the sampling groove 7. The other end of the sampling tube 1032 extends to the outside of the moving rod 9 and is fixedly disposed in connection with the airbag 1036. A limiting groove 1041 communicating with the guide groove 1035 is horizontally opened on the push block 1034. A limiting block 1042 is slidably arranged inside the limiting groove 1041. The limiting block 1042 slides along the opening direction of the limiting groove 1041. One end of the limiting block 1042 can extend into the interior of the guide groove 1035 and abut against the inner wall of the guide groove 1035. When the limiting block 1042 abuts against the guide groove 1035, the sampling groove 7 can be sealed. A second spring 1043 is fixedly arranged between the side of the limiting block 1042 located inside the limiting groove 1041 and the inner wall of the limiting groove 1041. When the second spring 1043 is not under force, it is in a tensioned state. At this time, the limiting block 1042 abuts against the guide groove 1035.
[0027] like Figure 2 As shown, a turbulence block 1051 is fixedly installed on the end of the stirring rod 6 away from the rotating shaft 4. The turbulence block 1051 rotates synchronously with the stirring rod 6, and the turbulent flow state allows the fluids in different areas to mix more thoroughly, improving the efficiency of fluid mixing. The mixing tank 1 has a discharge port 1061 that communicates with the hollow structure 2. The discharge port 1061 is connected to an external discharge pipe, and a valve is installed on the discharge pipe. After the fluid mixing is completed, the valve can be opened to discharge and collect the mixed fluid through the discharge port 1061 and the discharge pipe.
[0028] First, the fluid to be mixed enters the hollow structure 2 through the feed pipe 3. Then, the turntable 5 is rotated to drive the rotating shaft 4 to rotate, which in turn drives the stirring rod 6 to rotate, thus mixing the fluid. During the mixing process, the sealing structure is used to remove the seal on the sampling tank 7, and the mixed fluid enters the sampling tank 7. Then, the sample in the sampling tank 7 is taken out through the sampling structure. This device can take samples during the mixing process and can obtain fluid samples at different mixing stages in real time, which is convenient for timely monitoring of the mixing state and effect of the fluid, so as to adjust the stirring process according to the sample conditions and improve the mixing quality.
[0029] Pulling the push plate 1013 causes the sealing plate 1012 to slide within the sealing groove 1011, moving the sealing plate 1012 away from the sampling groove 7. Simultaneously, as the sealing plate 1012 moves, it causes the positioning plate 1022 to slide within the positioning groove 1021, compressing the first spring 1023. This releases the seal on the sampling groove 7. After the sample enters the sampling groove 7, releasing the push plate 1013 allows the first spring 1023 to reset and push the positioning plate 1022 to slide within the positioning groove 1021. The positioning plate 1022 then causes the sealing plate 1012 to slide within the sealing groove 1011 towards the sampling groove 7, thus sealing the sampling groove 7.
[0030] By inserting the sampling tube 1032 into the sliding groove 1031, the sampling tube 1032 drives the sampling head 1033 to move towards the guide groove 1035. When the sampling head 1033 abuts against the limiting block 1042, the limiting block 1042 slides into the limiting groove 1041 under the action of abutment, so that the limiting block 1042 is housed inside the limiting groove 1041, realizing separation from the guide groove 1035. When the limiting block 1042 moves, it compresses the second spring 1043, thereby canceling the seal on the guide groove 1035. At this time, the sampling head 1033 moves through the guide groove 1035 to the sampling groove. The sample is then placed inside the sampling slot 7 and squeezed into the air bladder 1036. Through the elastic back suction of the air bladder 1036, the sample in the sampling slot 7 is adsorbed into the sampling tube 1032. Then the sampling tube 1032 is taken out for observation. During the removal process, the sampling head 1033 moves away from the guide groove 1035, so that the sampling head 1033 is separated from the guide groove 1035. At this time, the second spring 1043 resets and pushes the limiting block 1042 to move in the limiting groove 1041 towards the guide groove 1035, so that the limiting block 1042 abuts against the inner wall of the guide groove 1035, thereby sealing the guide groove 1035.
[0031] After sampling, the moving rod 9 is rotated within the threaded hole 8. Under the action of the threaded structure, the moving rod 9 pushes the push block 1034 to slide within the sampling groove 7. Under the action of the thrust, the push block 1034 pushes the fluid sample towards the one-way valve 10, and then discharges it into the interior of the hollow structure 2 through the one-way valve 10.
[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, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
