Description

Technical Field

[0001] The present invention relates to the technical field of veterinary drug production, and particularly to a pH testing device for use in the veterinary drug processing process. Background Art

[0002] In the veterinary drug processing process, precise control of the fermentation link is crucial. Among them, the stable regulation and accurate measurement of the pH value are key factors in ensuring the quality of veterinary drugs. Traditional veterinary drug processing and fermentation operations mostly rely on manual experience for pH value adjustment and detection. Manually adding alkaline solutions or pure water to adjust the pH value is not only inefficient but also difficult to ensure the accuracy of the addition amount, easily leading to an unstable fermentation environment and affecting the fermentation effect of veterinary drug raw materials and the quality of the final product.

[0003] At the same time, existing pH value detection methods often require manual sampling from the fermentation tank at regular intervals for detection and analysis in a laboratory environment. This off-line detection method not only consumes manpower and material resources but also has an obvious lag in the detection results, unable to reflect the pH value change of veterinary drug raw materials in the fermentation tank in real time, and difficult to effectively intervene and control the fermentation process in a timely manner. Moreover, during the detection process, due to the lack of effective control of the detection environment, factors such as light may affect the stability of reagents such as phosphate diluent, thereby reducing the accuracy of the detection results. In addition, when existing fermentation equipment performs operations such as stirring, humidifying, heating, cooling, and gas supply on veterinary drug raw materials, each functional component is relatively independent, lacking systematic coordinated control, and it is difficult to achieve comprehensive, precise, and automated control of the fermentation environment. Therefore, there is an urgent practical need to develop a veterinary drug processing pH testing device that can achieve automated pH value adjustment and real-time precise detection, and at the same time has the function of coordinated control of multiple parameters of the fermentation environment.

The hollow cylinders 971 on the two blanking assemblies 97 are respectively installed at the left and right ends of the top of the mixing tank 92. The tops of the hollow cylinders 971 on the left and right sides are respectively installed with the bottom of the diluent tank 912 and the bottom of the fermentation tank 5. A fourth rotating shaft 972 capable of rotating around its own axis is installed at the central position of the hollow cylinder 971 through a bearing, and the front end of the fourth rotating shaft 972 is connected to the driver 98.

[0024] As a preferred solution, further, the inner cavity volume of the groove 974 on the left hollow cylinder 971 is ten times that of the groove 974 on the right hollow cylinder 971, so as to dilute the veterinary drug raw materials in proportion, thereby improving the measurement accuracy of the pH meter 911 for the pH value of the veterinary drug raw materials.

[0025] Working principle: Step 1: The fermentation tank 5 provides a fermentation space for the veterinary drug raw materials. The temperature sensor 10 and the humidity sensor 11 monitor the temperature and humidity indicators of the veterinary drug raw materials. The internal heater of the fermentation tank 5 can raise the temperature of the veterinary drug raw materials, and the second solenoid valve 13 is opened to allow cooling water to pass through the fermentation tank 5 to cool the fermentation tank 5, realizing the normal fermentation of the fermentation tank 5. The first solenoid valve 12 is opened to provide oxygen for the survival of microorganisms in the veterinary drug raw materials and can also discharge the gas generated during fermentation, realizing the fermentation of the veterinary drug raw materials. Step 2: When the humidity exceeds the lower limit of the fermentation of the veterinary drug raw materials, the controller 4 starts the right water tank 3. The pure water enters from the right side of the valve body 871, and the water pressure pushes the valve core 872 to move leftward. The pure water enters the water wheel housing 86, and the water wheel 89 rotates under the action of the water pressure. The second rotating shaft 88 drives the convex block 811 to do circular motion. At the same time, the pure water comes out from the right side of the water wheel housing 86 and enters the water storage box 81. While the convex block 811 slides on the swing rod 813, the swing rod 813 drives the sector gear 812 to rotate clockwise and counterclockwise reciprocally. The sector gear 812 is in transmission with the straight gear 85 to drive the rotating block 83 to drive the nozzle 84 to swing left and right, expanding the spraying area of the nozzle 84, which can not only uniformly humidify the veterinary drug raw materials, but also comprehensively wash the fermentation tank 5. Step 3: When it is necessary to regularly monitor the pH value of the veterinary drug raw material fermentation, the controller 4 controls the operation of the driver 98, enabling the fourth rotating shaft 972 to drive the second turntable 973 to rotate. The left groove 974 carries the phosphate diluent in the diluent tank 912 into the mixing tank 92, and the right groove 974 samples the veterinary drug raw material and enters it into the mixing tank 92. Under the agitation of the second stirrer 96, the phosphate diluent dilutes the veterinary drug raw material in proportion. The pH meter 911 detects the pH value of the veterinary drug raw material. If the pH value exceeds the lower limit of the veterinary drug raw material fermentation, the controller 4 activates the left water tank 3. The water tank 3 allows the phosphate diluent to enter from the left side of the valve body 871, causing the valve core 872 to move to the right. The phosphate diluent enters the water wheel housing 86, and the water wheel 89 drives the convex block 811 to perform a circular motion. Under the cooperation of the swing rod 813, the sector gear 812, and the spur gear 85, the nozzle 84 swings to spray the phosphate diluent comprehensively on the veterinary drug raw material, adjusting the pH value of the veterinary drug raw material and replacing manual pH value detection. Step 4: When it is necessary to observe the fermentation situation of the veterinary drug raw material, after the phosphate diluent dilutes the veterinary drug raw material, it is left stationary for a period of time. Then, the baffle 95 is rotated, and further, the third rotating shaft 945 drives the first turntable 943 to rotate. When the baffle 95 moves away from the glass plate 93 and the elastic force of the spring 947 pushes the ball 948 into the right card slot 946, the first turntable 943 is positioned. The first contact 942 contacts the second contact 944, and the waterproof lamp 99 emits light, providing a view for the mixing tank 92. The staff observes the suspension state of the veterinary drug raw material through the glass plate 93 as a reference factor for the fermentation of the veterinary drug raw material.
