Description

Technical Field

[0001] This application relates to the field of material analysis instrument technology, and in particular to a density and refractometer. Background Technology

[0002] A density meter is an instrument for measuring the density of liquids. Liquid density is one of the important physical properties of liquids, and the density method is a commonly used detection method in food analysis and food safety testing. Density can help understand the purity and adulteration of a substance. With the development of technology, rapid density measurement has been widely applied in many fields. A refractometer, also known as a refractive index meter, is an instrument that uses light to test the concentration of a liquid. It can be used to determine refractive index, birefringence, optical properties, etc., and is one of the important physical constants of a substance. Refractometers have a wide range of applications and can be used to determine the refractive index (nD) and average dispersion (nF-nC) of transparent and translucent liquids or solids, with a primary focus on transparent liquids.

[0003] With the development of industry, more and more industries need to use refractometers and densitometers to test and analyze their raw materials. However, in the process of testing raw materials, it is necessary to use a syringe to put the substance to be tested into the sample cell of the instrument, and this manual feeding method limits the testing efficiency.

[0004] Therefore, this patent needs to be upgraded and modified based on the existing technology. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a density and refractometer that overcomes these limitations. It aims to solve the problem that when raw materials are tested and analyzed using a refractometer and a density meter, manual feeding with a syringe is required during the testing process, which limits the testing efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution: a density and refractometer, comprising a density meter, a refractometer, and a rubber hose, wherein the refractometer is fixedly connected to the top of the density meter, a turntable is rotatably connected to one side of the density meter, a peristaltic rotating shaft is rotatably connected to the outside of the turntable, the rubber hose is attached to the outside of the peristaltic rotating shaft, a top cover is fixedly connected to the outside of the turntable, and the rubber hose is attached to the top of the inside of the top cover.

[0007] By adopting the above technical solution, the peristaltic shaft on the outer side of the turntable rotates with the turntable. The peristaltic shaft is equipped with a top cover and is arranged in a circle on the outer side of the turntable. During the rotation of the peristaltic shaft with the turntable, it will squeeze the rubber hose, thereby realizing the discharge of the test material inside the rubber hose into the densitometer and refractometer. Since the peristaltic shaft is set to rotate on the outer side of the turntable, it will also rotate with the turntable when it rotates and squeezes the rubber hose, thus preventing the rubber hose from moving during the rotation of the turntable.

[0008] As a preferred technical solution of this application, a diverter is fixedly connected to the end of the rubber hose, and a connecting block is fixedly connected to the side of the diverter, and the connecting block is fixedly connected to the side of the densitometer.

[0009] By adopting the above technical solution and setting up the diversion tube, the raw material inside the rubber hose can be separated into two parts, which are then sent to the density meter and the interior for testing, respectively.

[0010] As a preferred technical solution of this application, the refractometer is provided with a refractive detection port on the top, the shunt tube is fixedly connected to the top of the refractometer tube, and the other end of the refractometer tube is fixedly connected to the outside of the refractive detection port.

[0011] By adopting the above technical solution, a portion of the raw material is separated through a split tube and enters the refractive index detection port inside the density meter for corresponding testing.

[0012] As a preferred technical solution of this application, the density meter is provided with a density detection port on its side, and a density detection tube is fixedly connected to the other end of the shunt tube, with the other end of the density detection tube fixedly connected to the outside of the density detection port.

[0013] By adopting the above technical solution, after the raw material is separated by the split tube, the other part enters the density detection port on the side of the density meter through the density detection tube for corresponding detection.

[0014] As a preferred technical solution of this application, the densitometer is provided with a top display panel on its side, and a top operation panel is provided on the side of the top display panel; the refractometer is provided with a bottom display panel on its side, and a bottom operation panel is provided on the side of the bottom display panel.

[0015] By adopting the above technical solution, the top and bottom display panels can display the corresponding monitoring data for staff to observe, and the top and bottom operation panels are set up to allow staff to perform further calculations on the test data.

[0016] As a preferred technical solution of this application, a drive shaft is fixedly connected to the middle position of the turntable, and a drive motor is fixedly connected to the end of the drive shaft. The drive motor drives the drive shaft to rotate, and then the drive shaft drives the turntable to rotate.

[0017] By adopting the above technical solution, the process of detecting the peristalsis of raw materials inside the rubber hose is achieved by driving the motor.

[0018] As a preferred technical solution of this application, a support rod is fixedly connected to the bottom of the top cover on the side of the density meter, a tray is fixedly connected to the outside of the support rod, and a drive motor is fixedly connected to the top of the tray.

[0019] By adopting the above technical solution, the support rod can provide some support for the rubber hose, and the support plate can fix the drive motor.

[0020] The beneficial effects of this application are: In this invention, by rotating the turntable, the peristaltic shaft on the outer side of the turntable squeezes the rubber hose, causing the detection liquid in the rubber hose to move in a certain direction, thereby achieving rapid delivery of the detection material. Moreover, this squeezing and releasing process can precisely control the flow rate and velocity of the detection material to ensure the accuracy of the detection data. Attached Figure Description

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

[0024] Reference Figure 1-3 A density and refractometer is provided, comprising a density meter 1, a refractometer 2, and a rubber hose 6. The refractometer 2 is fixedly connected to the top of the density meter 1. The density meter is an Anton Paar DMA5000M model, which calculates the density of a substance by measuring its mass and volume. The refractometer is a Rudolph Research Analytical J257 model, which determines the properties of a substance by measuring its refractive index. A turntable 12 is rotatably connected to one side of the density meter 1. A peristaltic rotating shaft 13 is rotatably connected to the outside of the turntable 12. The rubber hose 6 is attached to the outside of the peristaltic rotating shaft 13. The outside of the turntable 12 is fixed. A top cover 3 is connected, and a rubber hose 6 is attached to the top of the top cover 3. By rotating the turntable 12, the peristaltic rotating shaft 13 on the outside of the turntable 12 rotates accordingly. The peristaltic rotating shaft 13 is equipped with three top covers arranged in a circle on the outside of the turntable 12. During the rotation of the peristaltic rotating shaft 13 with the turntable 12, it will squeeze the rubber hose 6, thereby allowing the raw material inside the rubber hose 6 to be discharged into the detection pools of the density meter 1 and the refractometer 2. Since the peristaltic rotating shaft 13 is set to rotate on the outside of the turntable 12, the peristaltic rotating shaft 13 will also rotate itself when it rotates and squeezes the rubber hose 6, thereby preventing the rubber hose 6 from moving during the rotation of the turntable 12.

[0025] In this embodiment, as Figure 1 - Figure 3 As shown, a diverter tube 8 is fixedly connected to the end of the rubber hose 6, and a connecting block 9 is fixedly connected to the side of the diverter tube 8. The connecting block 9 is fixedly connected to the side of the densitometer 1. Through the setting of the diverter tube 8, the raw material inside the rubber hose 6 can be separated into two parts, which are then sent into the densitometer 1 and the refractometer 2 for testing, respectively.

[0026] In this embodiment, as Figure 1 - Figure 3 As shown, the refractometer 2 has a refractive detection port 203 on its top, and a refractive detection tube 10 is fixedly connected to the top of the split tube 8. The other end of the refractive detection tube 10 is fixedly connected to the outside of the refractive detection port 203. A portion of the raw material is separated through the split tube 8 and enters the refractive detection port 203 inside the densitometer 1 for corresponding detection.

[0027] In this embodiment, as Figure 1 - Figure 3 As shown, the density meter 1 has a density detection port 103 on its side, and the other end of the diversion tube 8 is fixedly connected to a density detection tube 11. The other end of the density detection tube 11 is fixedly connected to the outside of the density detection port 103. After the raw material is separated by the diversion tube 8, the other part enters the density detection port 103 on the side of the density meter 1 through the density detection tube 11 for corresponding detection.

[0028] In this embodiment, as Figure 1 - Figure 3 As shown, the densitometer 1 has a top display panel 101 on its side, and a top operation panel 102 is located on the side of the top display panel 101. The refractometer 2 has a bottom display panel 201 on its side, and a bottom operation panel 202 is located on the side of the bottom display panel 201. The top display panel 101 and the bottom display panel 201 can display the corresponding monitoring data for the staff to observe. The top operation panel 102 and the bottom operation panel 202 are set up so that the staff can perform further calculations on the test data.

[0029] In this embodiment, as Figure 1 - Figure 3 As shown, a drive shaft 14 is fixedly connected to the middle position of the turntable 12, and a drive motor 7 is fixedly connected to the end of the drive shaft 14. The drive motor 7 drives the drive shaft 14 to rotate, and then drives the turntable 12 to rotate. Thus, the drive motor 7 drives the process of detecting the peristalsis of the raw material inside the rubber hose 6.

[0030] In this embodiment, as Figure 1 - Figure 3 As shown, a support rod 4 is fixedly connected to the bottom of the top cover 3 on the side of the densitometer 1. A tray 5 is fixedly connected to the outside of the support rod 4. A drive motor 7 is fixedly connected to the top of the tray 5. The support rod 4 can provide some support for the rubber hose 6, and the tray 5 can fix the drive motor 7.

[0031] Working principle: The starting end of the rubber hose 6 is connected to the test material tank. The drive motor 7 drives the drive shaft 14 to rotate. During the rotation of the drive shaft 14, the turntable 12 rotates. The peristaltic shaft 13 inside the turntable 12 rotates as well. During the rotation of the peristaltic shaft 13, it will squeeze the rubber hose 6 at the top, causing the test material inside the rubber hose 6 to move in a certain direction. When the test material enters the diversion tube 8, the test material is separated into two parts by the diversion tube 8. They enter the refractive detection port 203 and the density detection port 103 respectively through the refractive detection tube 10 and the density detection tube 11. Then, they are detected by the density meter 1 and the refractometer 2. In this system, by setting up a turntable 12, the peristaltic rotating shaft 13 on the outer side of the turntable 12 squeezes the rubber hose 6, causing the detection liquid in the rubber hose 6 to move in a certain direction, thereby realizing the rapid delivery of the detection material. Moreover, this squeezing and releasing process can precisely control the flow rate and velocity of the detection material to ensure the accuracy of the detection data.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
