Description

Technical Field

[0001] The utility model belongs to the technical field of spinning bath detection, and particularly relates to a device for measuring the concentration of spinning bath solution at a constant temperature. Background Technique

[0002] The spinning bath, also known as the coagulation bath, is a solution used in the wet spinning process of chemical fibers. In this process, after the spinning dope is extruded from the spinneret holes, it passes through the spinning bath to solidify into the nascent fiber; the spinning bath plays a key role in the solidification process, including the dual effects of physical and chemical actions; the concentration of the spinning bath greatly affects the spinning process, and usually a refractometer is used to detect the concentration of the spinning bath.

[0003] Before the existing refractometer is used, it needs to be set up. Usually, it is set up by operating the touch screen display on the refractometer. The display screen is exposed to the air for a long time, which easily makes the surface of the display screen contaminated with dust and dirt, affecting the touch screen effect of the display screen, thus affecting the normal use of the display screen. Moreover, most of the existing refractometers do not have a leveling function. When the refractometer is placed on a workbench with an uneven surface, the inclined refractometer is likely to affect the measurement accuracy to a certain extent, thereby reducing the detection efficiency.

[0004] Therefore, a device for measuring the concentration of spinning bath solution at a constant temperature is needed to solve the problems that the display screen on the existing refractometer is easily contaminated with dust and affects the use, and the refractometer is not easy to be quickly leveled according to the flatness of the workbench. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for measuring the concentration of spinning bath solution at a constant temperature to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A device for measuring the concentration of spinning bath solution at a constant temperature, including a refractometer body, a circulating water inlet and a circulating water outlet are arranged on the outer wall of one side of the refractometer body, a dust-proof mechanism is arranged on the outer wall of one end of the refractometer body corresponding to the display screen, and a leveling component is arranged on the bottom surface of the refractometer body;

[0007] The dust-proof mechanism includes a transparent dust-proof cover and a guide plate. The transparent dust-proof cover is installed on the outer wall of one end of the refractometer body corresponding to the display screen through a hinge. One end of the guide plate is fixedly connected to the outer wall of one end of the refractometer body. A connecting block is fixedly connected to the outer wall of one side of the transparent dust-proof cover. A limiting sleeve is fixedly connected to the outer wall of one end of the connecting block. A guide groove is opened on the outer wall of the end of the guide plate far away from the refractometer body. A slider is slidably connected inside the guide groove. One end of the slider far away from the guide groove is fixedly connected to an insertion plate. A counterweight block is fixedly connected to the outer wall of the end of the insertion plate far away from the slider.

[0008] It should be noted in the solution that the leveling component includes a bottom plate. Fixed frames are fixedly connected to the four corners of the top surface of the bottom plate. An adjusting rod is slidably inserted into the center of the top surface of the fixed frame. A connecting shaft is fixedly connected to the center of the bottom surface of the adjusting rod. An adjusting screw is threadedly inserted into the outer wall of one side of the fixed frame. A wedge plate is rotatably connected to one side of the adjusting screw located inside the fixed frame. A support column is fixedly connected to the center of the top surface of the bottom plate. A ball head is fixedly connected to the top end of the support column. The ball head is rotatably embedded in the bottom surface of the refractometer body.

[0009] It is further worth noting that a water inlet pipe is fixedly connected to the circulating water inlet, and a water outlet pipe is fixedly connected to the circulating water outlet. The same constant temperature water bath device is installed at one end of the water inlet pipe away from the circulating water inlet and at one end of the water outlet pipe away from the circulating water outlet.

[0010] It is even further necessary to note that a dispersion value scale circle is provided on the outer wall of one side of the refractometer body, and a refraction scale adjusting handwheel is provided on the outer wall of one side of the refractometer body.

[0011] As a preferred implementation manner, the insertion plate and the counterweight are slidably inserted into the inside of the limit sleeve, and the two fixed frames at the same end are symmetrically distributed.

[0012] As a preferred implementation manner, the top surfaces of the four adjusting rods are fixedly connected to the bottom surface of the refractometer body, and the bottom end of the connecting shaft is set to be arc-shaped and is in contact with the wedge surface of the corresponding wedge plate.

[0013] Compared with the prior art, a device for measuring the concentration of spinning bath solution at a constant temperature provided by the present utility model has at least the following beneficial effects:

[0014] (1) Through the action of the dust-proof mechanism, when the refractometer is not in use, the transparent dust-proof cover protects the display screen on the refractometer from dust. When using the refractometer, push up the insertion plate to drive the counterweight to separate from the limit sleeve, release the locking of the transparent dust-proof cover, and rotate the transparent dust-proof cover to expose the display screen, so that the settings before using the refractometer body can be made, effectively avoiding the problem that the display screen on the refractometer is easily contaminated with dust and affects the use.

[0015] (2) Through the action of the leveling component, rotate the adjusting screw to push the wedge plate to move, so that the wedge plate pushes the adjusting rod to move upward on the fixed frame. With the rotational cooperation of the ball head and the refractometer body, the height of the adjusted corner of the refractometer body rises. Adjust the four adjusting rods respectively to quickly level the refractometer body, thereby improving the accuracy of the refractometer during use. The operation is simple, effectively avoiding the problem that the refractometer is not easy to be quickly leveled according to the flatness of the workbench. Description of the Drawings

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] Please refer to Figures 1-4 , the present utility model provides a device for measuring the concentration of spinning bath solution at a constant temperature, including a refractometer body 1. A circulating water inlet 2 and a circulating water outlet 3 are arranged on the outer wall of one side of the refractometer body 1. A dust-proof mechanism 4 is arranged on the outer wall of one end of the refractometer body 1 corresponding to the display screen, and a leveling assembly 5 is arranged on the bottom surface of the refractometer body 1;

[0023] The dust-proof mechanism 4 includes a transparent dust-proof cover 41 and a guide plate 42. The transparent dust-proof cover 41 is installed on the outer wall of one end of the refractometer body 1 corresponding to the display screen through a hinge. One end of the guide plate 42 is fixedly connected to the outer wall of one end of the refractometer body 1. A connecting block 43 is fixedly connected to the outer wall of one side of the transparent dust-proof cover 41. A limiting sleeve 44 is fixedly connected to the outer wall of one end of the connecting block 43. A guide groove 45 is opened on the outer wall of the end of the guide plate 42 far away from the refractometer body 1. A slide block 46 is slidably connected inside the guide groove 45. An insert plate 47 is fixedly connected to the outer wall of the end of the slide block 46 far away from the guide groove 45. A counterweight block 48 is fixedly connected to the outer wall of the end of the insert plate 47 far away from the slide block 46.

[0024] Further, as shown in Figure 1 , Figure 2 and Figure 4As shown, it is worth specifically explaining that the leveling component 5 includes a bottom plate 51. Fixed frames 52 are fixedly connected to the four corners of the top surface of the bottom plate 51. An adjusting rod 53 is slidably inserted into the center of the top surface of the fixed frame 52. A connecting shaft 54 is fixedly connected to the center of the bottom surface of the adjusting rod 53. An adjusting screw 55 is threadedly inserted into one outer wall of the fixed frame 52. One side of the adjusting screw 55 located inside the fixed frame 52 is rotatably connected to a wedge plate 56. A support column 57 is fixedly connected to the center of the top surface of the bottom plate 51. A ball head 58 is fixedly connected to the top end of the support column 57. The ball head 58 is rotatably embedded in the bottom surface of the refractometer body 1.

[0025] Further, as Figure 1 and Figure 2 shown, it is worth specifically explaining that a water inlet pipe 6 is fixedly connected to the circulating water inlet 2, and a water outlet pipe 7 is fixedly connected to the circulating water outlet 3. The same constant temperature water bath device 8 is installed at one end of the water inlet pipe 6 away from the circulating water inlet 2 and one end of the water outlet pipe 7 away from the circulating water outlet 3.

[0026] Further, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, it is worth specifically explaining that a dispersion value scale circle 9 is provided on one outer wall of the refractometer body 1, and a refraction scale adjusting handwheel 10 is provided on one outer wall of the refractometer body 1.

[0027] Further, as Figure 3 and Figure 4 shown, it is worth specifically explaining that the insertion plate 47 and the counterweight 48 are slidably inserted into the limit sleeve 44. Through the cooperation of the insertion plate 47, the counterweight 48 and the limit sleeve 44, the transparent dust cover 41 is locked and limited. The two fixed frames 52 at the same end are symmetrically distributed, which is convenient for the operator to rotate the adjusting screw 55 to level the refractometer body 1.

[0028] Further, as Figure 4 shown, it is worth specifically explaining that the top surfaces of the four adjusting rods 53 are fixedly connected to the bottom surface of the refractometer body 1. The bottom end of the connecting shaft 54 is circular arc-shaped and contacts the wedge surface of the corresponding wedge plate 56. By pushing the wedge plate 56 to move with the adjusting screw 55, the adjusting rod 53 is further pushed to move up and down, so as to level the refractometer body 1.

[0029] In summary: Before using the device, the operator first pushes the insertion plate 47 and the counterweight 48 upward. Under the cooperation of the guiding groove 45 of the slider 46, the insertion plate 47 and the counterweight 48 move upward on the guiding plate 42. At this time, the insertion plate 47 and the counterweight 48 are separated from the limiting sleeve 44, unlocking the transparent dust-proof cover 41. Then the operator can rotate the transparent dust-proof cover 41 to expose the display screen on the refractometer body 1, so as to perform the pre-use settings on the refractometer body 1. Similarly, after the device is used, the above steps are operated in reverse to reset the transparent dust-proof cover 41 and protect the display screen on the refractometer body 1 from dust, effectively avoiding the problem that the display screen on the refractometer is easily contaminated with dust and affects the use.

[0030] When the refractometer body 1 is placed on a workbench with an uneven surface and needs to be leveled, just rotate the adjusting screw 55. Under the action of the thread, the adjusting screw 55 pushes the wedge plate 56 to move inside the fixing frame 52. The wedge surface of the wedge plate 56 contacts the arc-shaped bottom end of the adjusting rod 53. As the wedge plate 56 gradually moves, the wedge plate 56 pushes the connecting shaft 54 to drive the adjusting rod 53 to move upward on the fixing frame 52. Under the rotational cooperation of the ball head 58 and the refractometer body 1, the height of the adjusted corner of the refractometer body 1 rises. Adjust the four adjusting rods 53 respectively to quickly level the refractometer body 1, thereby improving the accuracy of the refractometer body 1 during use. Then turn on the constant temperature water bath device 8, and the aqueous solution with a constant temperature circulates through the water inlet pipe 6 and the water outlet pipe 7 inside the refractometer body 1 to ensure that the temperature of the sample is constant during detection, avoiding the deviation caused by temperature changes during refractometer measurement. The operation is simple, effectively avoiding the problem that the refractometer is not easy to be quickly leveled according to the flatness of the workbench.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
