Description

Technical Field

[0001] This invention belongs to the field of acid-base testing technology, specifically, it relates to a mixed liquid acid-base concentration detector. Background Technology

[0002] Accurate measurement of the acid-base concentration of mixed liquids is crucial in numerous fields, including chemical production, environmental monitoring, and new energy material research and development. In the field of new energy material research and development, the production process of cellulosic ethanol has stringent requirements for acid-base concentration control. Cellulosic ethanol is produced through hydrolysis and fermentation of lignocellulose raw materials. During the hydrolysis stage, the pH of the solution directly affects the decomposition efficiency of cellulose and the yield of sugars. During fermentation, acid-base imbalance inhibits microbial activity, leading to a decrease in ethanol yield. Traditional acid-base concentration detection methods mainly rely on manual sampling followed by the use of test strips or titration. This method is not only inefficient but also cannot achieve real-time monitoring, making it difficult to meet the requirements of dynamic acid-base concentration control in the industrial production of cellulosic ethanol. With the development of automation technology, various types of acid-base concentration meters have emerged on the market. These instruments are mostly based on electrochemical or optical principles and can quickly and accurately measure the acidity and alkalinity of liquids.

[0003] However, existing acid-base concentration meters have certain limitations in their detection methods. Currently, most acid-base concentration meters use a single detection probe, which can typically only move and detect along the vertical axis. In the cellulosic ethanol production solution system, the uneven distribution of raw material particles and the local accumulation of microbial metabolites during fermentation can lead to significant acid-base concentration gradients in the horizontal direction. Existing acid-base concentration meters cannot comprehensively detect different locations on the same horizontal plane. This detection method means that the instrument can only acquire changes in acid-base concentration in the vertical direction and cannot effectively capture the concentration gradient or stratification phenomenon in the horizontal direction of the cellulosic ethanol production solution.

[0004] Because existing acid-base concentration meters cannot effectively detect all points on the same horizontal plane, the acquired data is incomplete and cannot accurately reflect the acid-base concentration distribution of the entire cellulosic ethanol production solution. This can cause process deviations in the hydrolysis and fermentation stages of cellulosic ethanol production, leading to raw material waste, increased energy consumption, and reduced ethanol yield. Furthermore, the limited scope of the test results can cause erroneous judgments in experimental research and quality testing of cellulosic ethanol, hindering technological development and production practices in related fields. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a mixed liquid acid-base concentration detector to solve the problem of the single detection direction mentioned in the background art.

[0006] To achieve the aforementioned objectives, the technical solution adopted by this invention includes:

[0012] Furthermore, the lifting mechanism includes a lead screw, a gear, and a ball nut; the inner bottom surface and the inner top surface of the mixing cylinder are rotatably connected to the rotating plate, the top surface and the bottom surface of the lead screw are respectively rotatably connected to the two rotating plates, the gear is coaxially fixed on the lead screw and can mesh with the incomplete internal gear ring; the ball nut is screwed onto the lead screw, and the probe is detachably fixed on the ball nut.

[0031] The present invention aims to introduce and explain the structural composition of a mixed liquid acid-base concentration detector and the cooperation relationship between the various components. Unless otherwise specified, the dimensions, materials and manufacturing processes of the various components in the mixed liquid acid-base concentration detector in the present invention can be selected according to specific circumstances, and no special limitations or explanations are made here.

[0032] Furthermore, to provide the public with a better understanding of the present invention, certain specific details are described in detail in the following description of the invention. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0033] Please refer to the following: Figures 1-3 This embodiment provides a mixed liquid acid-base concentration detector, including a mixing cylinder 1, a stirring assembly 2, a rotating plate 3, an incomplete internal gear ring 4, a lifting mechanism 5, a probe 6, and a display screen 7;

[0034] The stirring assembly 2 is rotatably disposed inside the mixing cylinder 1, and the rotating plate 3 is rotatably connected inside the mixing cylinder 1 and connected to the stirring assembly 2. It should be understood that the stirring assembly 2 can stir the material inside the mixing cylinder 1. The stirring assembly 2 is connected to the rotating plate 3, and the rotation of the stirring assembly 2 will drive the rotating plate 3 to rotate together.

[0035] The display screen 7 is mounted on the mixing drum 1 and connected to the probe 6. The lifting mechanism 5 is rotatably mounted on the rotating plate 3, and the probe 6 is mounted on the lifting mechanism 5. The rotation of the lifting mechanism 5 drives the probe 6 to rise and fall. Preferably, the probe 6 is detachably mounted on the lifting mechanism 5. It should be understood that the lifting mechanism 5 is rotatably mounted on the rotating plate 3, meaning the lifting mechanism 5 can rotate. Simultaneously, since the rotating plate 3 is rotatable and connected to the stirring assembly 2, the lifting mechanism 5 also revolves around the stirring assembly 2. Different directions of rotation of the lifting mechanism 5 can cause the probe 6 to either rise or fall. Specifically, in this embodiment, clockwise rotation of the lifting mechanism 5 causes the probe 6 to fall, and counterclockwise rotation causes the probe 6 to rise. It should also be understood that the display screen 7 and the probe 6 are connected by a cable, and this cable is long enough to accommodate the rising and falling of the probe 6. The rotating plate 3 is preferably an annular plate.

[0036] The incomplete internal gear ring 4 is fixed inside the mixing cylinder 1. The rotation of the rotating plate 3 can drive the lifting mechanism 5 to rotate through the incomplete internal gear ring 4. That is, the lifting mechanism 5 revolves and rotates when it contacts the teeth of the incomplete internal gear ring 4, causing the probe 6 to rise or fall.

[0037] In this application, as the stirring assembly 2 rotates, it drives the lifting mechanism 5 to revolve. When the lifting mechanism 5 revolves and passes through the teeth of the incomplete internal gear ring 4, it rotates on its own axis, causing the probe 6 to rise and fall. That is, while stirring, the probe 6 can detect various points on the same horizontal plane and then rise and fall to a fixed height. Furthermore, while stirring, the probe 6 can detect various points around the solution at equal heights in the circumference, which can obtain more detection results and make the operator's judgment more accurate.

[0038] In other embodiments, the stirring assembly 2 includes a motor 21, a stirring shaft 22, stirring blades 23, and a connecting plate 24. The motor 21 is mounted on the mixing cylinder 1 and connected to the stirring shaft 22. The stirring blades 23 are mounted on the stirring shaft 22. One end of the connecting plate 24 is connected to the stirring shaft 22, and the other end is connected to the rotating plate 3. It should be understood that the output shaft of the motor 21 passes through the bottom of the mixing cylinder 1 and is coaxially fixed to the stirring shaft 22. The mixing cylinder 1 is leak-proof at the output shaft of the motor 21. At the same time, the stirring shaft 22 and the rotating plate 3 are coaxially arranged.

[0039] In other embodiments, the lifting mechanism 5 includes a lead screw 51, a gear 52, and a ball nut 53. A rotating plate 3 is rotatably connected to both the inner bottom and top surfaces of the mixing cylinder 1. The top and bottom surfaces of the lead screw 51 are rotatably connected to the two rotating plates 3, respectively. The gear 52 is coaxially fixed to the lead screw 51 and can mesh with the incomplete internal gear ring 4. The ball nut 53 is screwed onto the lead screw 51, and the probe 6 is detachably fixed to the ball nut 53. It should be understood that the vertical projections of the rotating plate 3 on the inner top surface and the rotating plate 3 on the inner bottom surface of the mixing cylinder 1 coincide. Ball bearings are provided at the top and bottom ends of the lead screw 51, and the ball bearings are connected to the rotating plates 3 via bearing seats. The ball nut 53 can be connected to the probe 6 via a snap-fit ​​or other structure. Preferably, a guide rod can also be provided on the rotating plate 3 or the bearing seat to limit the direction of the ball nut 53.

[0040] In other designs, a clamping mechanism 9 is also provided. The clamping mechanism 9 is located on the rotating plate 3 and can clamp the gear 52. A top plate 8 is also provided on the incomplete internal gear ring 4. The clamping mechanism 9 can release its clamp on the gear 52 when passing the top plate 8 and re-clamp the gear 52 after moving away from the top plate 8. During the production of cellulosic ethanol, its intermediate product is a solid-liquid mixture. During its revolution, the gear 52 is prone to rotation due to resistance, causing the probe 6 to rise or fall unexpectedly. By providing a top plate 8 on the teeth of the incomplete internal gear ring 4, the clamping mechanism 9 contacts the top plate 8 before the gear 52 contacts the incomplete internal gear ring 4, causing the clamping mechanism 9 to release its clamp on the gear 52. This allows the gear 52 to rotate upon contact with the teeth of the incomplete internal gear ring 4. After the clamping mechanism 9 moves away from the top plate 8, it re-clamps the gear 52, preventing the gear 52 from rotating due to the resistance of the solid-liquid mixture during its revolution, thus preventing the probe 6 from rising or falling unexpectedly.

[0041] In other embodiments, the clamping mechanism 9 includes a fixed plate 91, a lower clamping plate 92, an upper clamping assembly 93, and a driven plate 94. The fixed plate 91 is fixed to the rotating plate 3, and the lower clamping plate 92 is fixed to the fixed plate 91 and abuts against the bottom surface of the gear 52. The upper clamping assembly 93 is vertically and flexibly mounted on the fixed plate 91 and is elastic, allowing it to press against the gear 52 under elastic force. The driven plate 94 is fixed to the upper clamping assembly 93, and the top plate 8 has inclined surfaces on both sides, allowing the driven plate 94 to be lifted by the inclined surfaces. It should be understood that the top plate 8 is an arc-shaped wedge with inclined surfaces on both sides, and the inclined surfaces of the top plate 8 are located on the tooth side of the incomplete internal gear ring 4. As the driven plate 94 rotates with the rotating plate 3, it is lifted by the pressure of the inclined surfaces of the top plate 8, thereby lifting the upper clamping assembly 93 and moving it away from the gear 52, releasing the clamping state on the gear 52.

[0042] In other embodiments, the upper clamping assembly 93 includes a clamping connecting plate 931, a clamping spring 932, and an upper clamping plate 933. The clamping connecting plate 931 is fixed to the fixed plate 91 and connected to the upper clamping plate 933 via the clamping spring 932. The upper clamping mechanism can compress the gear 52 through the elastic force of the clamping spring 932, and the driven plate 94 is fixed to the upper clamping plate 933. It should be understood that the clamping spring 932 is always in a compressed state.

[0043] In other designs, the upper clamping plate 933 and the lower clamping plate 92 are both U-shaped. This U-shape allows for a larger clamping area for the gear 52, with the notch passing through the lead screw 51.

[0044] In other designs, the stirring blades 23 are oriented in different directions. This arrangement allows for more uniform mixing.

[0045] The aforementioned mixed liquid acid-base concentration detector can perform circumferential detection on solutions with equal height differences, resulting in more comprehensive detection data.

[0046] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It should not be considered that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the protection scope of the present invention.
