Description

Technical Field

[0001] This utility model relates to the field of automated biochemical analyzer technology, specifically to a particle size analyzer with a stirring function. Background Technology

[0002] A particle size analyzer is a device used to measure the size distribution of particles in a substance. It is widely used in many fields, such as materials science, chemical engineering, food, pharmaceuticals, mining, and environmental engineering. There are two main types of particle size analyzers: static analysis and dynamic analysis. Static analysis usually measures particle size through methods such as sieving, laser diffraction, or image analysis, while dynamic analysis usually estimates particle size by observing particle motion (such as motion in a fluid).

[0003] According to a published biochemical analyzer with stirring function (publication number: CN207457259U), a liquid stirrer is included. The stirrer comprises a fan-shaped container, on which a slide rail, side plate, fixed shaft, and motor are fixed. The output shaft of the motor is fixedly connected to a cam. The convex surface of the cam contacts one end of a movable rack embedded in the slide rail. The movable rack meshes with a half-gear, which is fixedly connected to one end of a long connecting rod. One end of the long connecting rod is hinged to the fixed shaft. The upper part of the long connecting rod is hinged to one end of a connecting rod. The other end of the connecting rod is hinged to the middle of a connecting rod two. One end of the connecting rod two is hinged to the upper-middle part of the long connecting rod two on the fixed shaft. The other end of the connecting rod two is hinged to the middle of a connecting rod three. One end of the connecting rod three is hinged to the upper-middle part of the long connecting rod three on the fixed shaft. However, in the above design, uneven mixing still occurs when analyzing the liquid, requiring improvement. Utility Model Content

[0004] This invention proposes a particle size analyzer with a stirring function, which solves the problems mentioned in the above documents.

[0005] The technical solution of this utility model is as follows: It includes a base, an analyzer fixedly connected to the top of the base, an analysis component, a display component, and an adjustment component on the top of the analyzer. An analysis tank is fixedly connected to the outer surface of the analyzer, and a stirring mechanism is provided inside the analysis tank. The stirring mechanism includes a motor, which is located on top of the analysis component. A rotating shaft is fixedly connected to the end of the motor's output shaft, and a transmission gear is fixedly connected to the circumferential surface of the rotating shaft. A rotating rod is rotatably connected to the bottom of the inner wall of the analysis tank, and a connecting gear is fixedly connected to the circumferential surface of the rotating rod. A mixing plate is fixedly connected to the circumferential surface of the rotating rod.

[0006] The inner wall of the analysis tank is provided with a groove, and a sliding block is slidably connected to the inner wall of the groove. A toothed disc is fixedly connected to the side of the sliding block, and a stirring plate is fixedly connected to the bottom of the toothed disc. The stirring design is beneficial to drive the stirring plate to make a circular motion when the toothed disc rotates, thereby mixing and stirring the liquid in the lower half of the analysis tank to make it uniform.

[0007] The transmission gear meshes with the connecting gear, and the connecting gear meshes with the gear disk. Both the connecting gear and the transmission gear are set as full gears. The above design is beneficial because when the transmission gear rotates, it drives the connecting gear to rotate, thereby driving the gear disk to rotate and move.

[0008] The mixing plates are arranged in a plurality of arrays along the circumference of the rotating rod. The side cross-section of the stirring plate is arc-shaped, which is beneficial for mixing the liquid.

[0009] The circumferential surface of the rotating rod is provided with a linear mixing mechanism, which includes a reciprocating sleeve rod. The reciprocating sleeve rod is fixedly connected to the circumferential surface of the rotating rod. A reciprocating threaded sleeve is threadedly connected to the circumferential surface of the reciprocating sleeve rod. A connecting plate is fixedly connected to the circumferential surface of the reciprocating threaded sleeve. A connecting shaft is rotatably connected to the inner sidewall of the connecting plate. A stirring plate is fixedly connected to the circumferential surface of the connecting shaft. The above design is beneficial to better mixing of materials when the stirring plate makes linear reciprocating motion.

[0010] A limiting rod is fixedly connected to the top of the connecting plate, and an abutment plate is fixedly connected to the bottom of the connecting plate. The design of the limiting rod is beneficial to drive the reciprocating threaded sleeve to move when the reciprocating sleeve rotates, and at the same time drive the limiting rod to make linear reciprocating motion, thereby making the reciprocating threaded sleeve make linear reciprocating motion.

[0011] The side section of the limiting rod is L-shaped, and the limiting rod is slidably connected to the inner wall of the analysis tank. The above design is beneficial for limiting the reciprocating thread sleeve.

[0012] The side cross-section of the connecting plate is concave, and the side cross-section of the abutting plate is L-shaped. The abutting plate is in contact with the stirring plate. The above design is beneficial to prevent the connecting shaft from rotating when the abutting plate is in contact with the stirring plate.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, the driving force of the motor drives the rotating shaft, transmission gear, connecting gear, gear plate, rotating rod, mixing plate, slide groove, stirring plate and other components to cooperate with each other. This enables the motor set on the top of the analysis component to start, thereby driving the rotating shaft fixed at the end of the output shaft to rotate. At the same time, it drives the transmission gear fixed on the circumference of the rotating shaft to rotate. The rotation of the transmission gear drives the meshing connecting gear to rotate. When the connecting gear rotates, it drives the rotating rod at the bottom of the inner wall of the analysis tank to rotate. When analyzing multiple liquids, this allows the liquids to be fully mixed.

[0015] 2. In this utility model, the rotational force of the rotating rod drives the reciprocating sleeve, reciprocating threaded sleeve, connecting plate, connecting shaft, stirring plate, contact plate, limiting rod, and other components to cooperate with each other. When the rotating rod rotates, it drives the reciprocating sleeve fixed on the circumferential surface to rotate, thereby causing the reciprocating threaded sleeve threadedly connected to the circumferential surface to move. When the reciprocating threaded sleeve moves, it drives the connecting plate fixed on the circumferential surface to move, thereby causing the limiting rod fixed on the top of the connecting plate to slide back and forth on the inner wall of the analysis tank. At the same time, it drives the reciprocating threaded sleeve to reciprocate. When mixing multiple liquids, uniform mixing is achieved through different movement modes. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] like Figures 1-5 As shown, this embodiment proposes a particle size analyzer with a stirring function, including a base 1, an analyzer 2 fixedly connected to the top of the base 1, an analysis component 3 disposed on the top of the analyzer 2, a display component 5 disposed on the top of the analyzer 2, an adjustment component 4 disposed on the top of the analyzer 2, an analysis tank 8 fixedly connected to the outer surface of the analyzer 2, and a stirring mechanism 6 disposed inside the analysis tank 8; the stirring mechanism 6 includes a motor 61 disposed on the top of the analysis component 3, a rotating shaft 62 fixedly connected to the end of the output shaft of the motor 61, a transmission gear 63 fixedly connected to the circumferential surface of the rotating shaft 62, a rotating rod 64 rotatably connected to the bottom of the inner wall of the analysis tank 8, a connecting gear 65 fixedly connected to the circumferential surface of the rotating rod 64, and a mixing plate 66 fixedly connected to the circumferential surface of the rotating rod 64.

[0026] The inner wall of the analysis tank 8 is provided with a groove 67, and a sliding block 69 is slidably connected to the inner wall of the groove 67. A toothed disc 68 is fixedly connected to the side of the sliding block 69, and a stirring plate 610 is fixedly connected to the bottom of the toothed disc 68. The design of the stirring plate 610 is conducive to driving the stirring plate 610 to make a circular motion when the toothed disc 68 rotates, thereby mixing and stirring the liquid in the lower half of the analysis tank 8 to make it uniform.

[0027] The transmission gear 63 meshes with the connecting gear 65, and the connecting gear 65 meshes with the gear disk 68. Both the connecting gear 65 and the transmission gear 63 are set as full gears. The above design is beneficial because when the transmission gear 63 rotates, it drives the connecting gear 65 to rotate, thereby driving the gear disk 68 to rotate and move.

[0028] The mixing plates 66 are configured in multiples and arranged circumferentially on the circumferential surface of the rotating rod 64. The side cross-section of the stirring plate 610 is set in an arc shape, which is beneficial for mixing the liquid more effectively.

[0029] In this embodiment, when analyzing the liquid, the operator first pours the liquid into the analysis tank 8. Then, the motor 61, which is set on top of the analysis component 3, is started, thereby driving the rotating shaft 62 fixed at the end of the output shaft to rotate. At the same time, the transmission gear 63 fixed on the circumferential surface of the rotating shaft 62 rotates. The rotation of the transmission gear 63 drives the meshing connecting gear 65 to rotate. When the connecting gear 65 rotates, it drives the rotating rod 64, which is rotating at the bottom of the inner wall of the analysis tank 8, to rotate. This causes the mixing plate 66, which is fixed on the circumferential surface of the rotating rod 64, to perform a circular motion to agitate and mix the liquid. When the connecting gear 65 rotates, it causes the meshing toothed disc 68 to be subjected to force, thereby causing the sliding block 69, which is fixed on the circumferential surface of the toothed disc 68, to slide on the inner wall of the groove 67. At the same time, it causes the toothed disc 68 to perform a circular motion. When the toothed disc 68 performs a circular motion, it causes the stirring plate 610, which is fixed at the bottom, to perform a circular motion to fully mix the liquid.

[0030] Example 2

[0031] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, a second embodiment is also proposed. The circumferential surface of the rotating rod 64 is provided with a linear mixing mechanism 7. The linear mixing mechanism 7 includes a reciprocating sleeve 71, which is fixedly connected to the circumferential surface of the rotating rod 64. The circumferential surface of the reciprocating sleeve 71 is threadedly connected to a reciprocating threaded sleeve 72. The circumferential surface of the reciprocating threaded sleeve 72 is fixedly connected to a connecting plate 73. The inner sidewall of the connecting plate 73 is rotatably connected to a connecting shaft 74. The circumferential surface of the connecting shaft 74 is fixedly connected to a stirring plate 75. The above design is beneficial to better mix the materials when the stirring plate 75 makes linear reciprocating motion.

[0032] The top of the connecting plate 73 is fixedly connected to a limiting rod 77, and the bottom of the connecting plate 73 is fixedly connected to an abutment plate 76. The design of the limiting rod 77 is conducive to driving the reciprocating threaded sleeve 72 to move when the reciprocating sleeve rod 71 rotates, and at the same time driving the limiting rod 77 to make linear reciprocating motion, thereby making the reciprocating threaded sleeve 72 make linear reciprocating motion.

[0033] The side section of the limiting rod 77 is L-shaped, and the limiting rod 77 is slidably connected to the inner wall of the analysis tank 8. The above design is beneficial for limiting the reciprocating thread sleeve 72.

[0034] The side section of the connecting plate 73 is concave, and the side section of the abutting plate 76 is L-shaped. The abutting plate 76 is in contact with the stirring plate 75. The above design is beneficial to prevent the connecting shaft 74 from rotating when the abutting plate 76 is in contact with the stirring plate 75.

[0035] In this embodiment, when the rotating rod 64 rotates, it drives the reciprocating sleeve 71 fixed on the circumferential surface to rotate, thereby causing the reciprocating threaded sleeve 72 threaded on the circumferential surface to move. When the reciprocating threaded sleeve 72 moves, it drives the connecting plate 73 fixed on the circumferential surface to move, thereby causing the limiting rod 77 fixed on the top of the connecting plate 73 to slide back and forth on the inner wall of the analysis tank 8. At the same time, it drives the reciprocating threaded sleeve 72 to reciprocate. The reciprocating motion of the reciprocating threaded sleeve 72 drives the connecting plate 73 to reciprocate, thereby driving the connecting shaft 74 rotating on the inner wall of the connecting plate 73 to reciprocate. At the same time, it drives the stirring plate 75 fixed on the circumferential surface of the connecting shaft 74 to reciprocate. When the stirring plate 75 reciprocates, it is subjected to the pressure of the liquid, causing the connecting shaft 74 to rotate, thereby causing the stirring plate 75 to move in an arc. When it moves to a certain position, it contacts the abutting plate 76 fixed at the bottom of the connecting plate 73, thereby stopping the rotation of the connecting shaft 74 and stopping the movement of the stirring plate 75, thus fully mixing the liquid.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
