Description

Technical Field

[0001] This invention belongs to the field of pH detection technology, specifically relating to a digester with pH detection and adjustment. Background Technology

[0002] Pepsin exists in the gastric mucosa of animals in its zymogen form. When it encounters hydrochloric acid, it is activated into active pepsin. The process of activating pepsin with dilute hydrochloric acid is called digestion. The optimal pH value for pepsin is 1.5-2.0. Therefore, when adding dilute hydrochloric acid for activation, it is necessary to detect the pH value in the digestion tank.

[0003] In related prior art, such as Chinese Patent No. CN220887548U, a pH precision control device for efficient enzyme conversion is disclosed, including a reaction vessel and a pH sensor. The pH sensor is fixedly installed inside the upper part of the reaction vessel. A fixing plate is fixedly installed on the top of the reaction vessel, and a horizontal plate is fixedly installed on the top of the fixing plate. Alkali tanks and acid tanks are respectively fixedly sleeved inside the two ends of the horizontal plate. A pump is fixedly connected to the outlet of both the alkali tank and the acid tank, and a connecting pipe is fixedly connected to the outlet of the pump. The lower end of the connecting pipe extends into the interior of the reaction vessel. Fixing pipes are fixedly installed on both sides of the interior of the reaction vessel, and the lower ends of the connecting pipes communicate with and are fixedly installed to the corresponding fixing pipes. This solution can fully mix the added acid and alkali solutions with the solution in the reaction vessel to ensure precise pH control of the solution in the reaction vessel.

[0004] However, in the extraction of pepsin, approximately 150L of drinking water, 7L-8L of hydrochloric acid, and 300KG of pig gastric mucosa are added to a digestion tank (reactor). This means that the actual amount of hydrochloric acid added is relatively small, and the rotation of the rotary tube is hindered by the pig gastric mucosa. In order for the rotary tube to rotate smoothly, the hydrochloric acid should have a certain flow rate and volume through the rotary tube (if the flow rate or volume is too low, the thrust is insufficient to overcome the resistance). The higher the flow rate and volume, the shorter the acid addition time, which in turn leads to a shorter rotation time of the rotary tube. A shorter rotation time cannot achieve a good mixing and stirring effect, which can easily lead to inaccurate pH value detection in the digestion tank. Utility Model Content

[0005] The present invention aims to provide a digester with pH detection and adjustment to solve the problem mentioned above where the poor mixing effect of existing digesters leads to inaccurate pH detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a digester with pH detection and adjustment, comprising...

[0007] The tank body has a top cover installed on top;

[0008] The pH sensor is installed on the side wall of the tank body, and the detection end of the pH sensor extends into the tank body.

[0009] A regulating tank is installed on the side wall of the tank body. A liquid pump is installed on the regulating tank, and a liquid supply pipe is installed on the liquid pump.

[0010] The stirring mechanism includes a drive unit, a rotating shaft, and stirring blades. The rotating shaft is rotatably connected to the top cover. The stirring blades are mounted on the rotating shaft. A liquid supply channel is provided axially on the top of the rotating shaft. A one-way valve is fixed on the side wall of the rotating shaft. The one-way valve is connected to the liquid supply channel. The drive unit is used to drive the rotating shaft to rotate.

[0011] A sealing assembly is installed on the top cover, and a liquid supply pipe is fixed to the sealing assembly and extends into the liquid supply channel. The sealing assembly is used to seal the liquid supply channel.

[0012] The principle and effects of this technical solution:

[0013] 1. The drive unit rotates the shaft and stirring blades, ensuring that the addition of acid and alkali solutions does not interfere with the stirring inside the tank. This allows for continuous stirring within the tank, resulting in more uniform mixing of the pharmaceutical materials. Consequently, the pH sensor can detect a more accurate pH value, and the pH sensor can make greater contact with the added solution, thereby improving reaction efficiency. Furthermore, the outlet direction of the one-way valve follows the rotation of the shaft, allowing for more uniform spraying of the pH adjusting solution (hydrochloric acid in this solution) into the mixture of water and pig gastric mucosa, further enhancing stirring efficiency.

[0014] 2. By fixing the supply pipe with a sealing assembly, the supply pipe will not rotate synchronously with the shaft when the shaft rotates, thus avoiding the shaft from becoming entangled or twisted due to rotation. Furthermore, the liquid pump draws acid / alkali solutions from the regulating tank, allowing the pH regulating solution in the regulating tank to enter the supply channel and then enter the tank body through a one-way valve, thereby regulating the pH of the pharmaceutical materials in the tank body. The sealing assembly prevents the pH regulating solution from flowing out from the gap between the supply channel and the supply pipe.

[0015] 3. The pH value inside the tank is detected by a pH sensor, and the tank is continuously stirred by a stirring mechanism. The pH adjusting liquid inside the tank is introduced into the tank by a liquid pump. Thus, the tank can perform the functions of continuous stirring, real-time pH monitoring, and subsequent pH adjustment after the drug material (which can be pepsin, with pepsin as the main target in this solution, but other applicable drug materials are also acceptable, not listed here) is added to the tank.

[0016] The present invention is further configured such that: the drive unit includes a motor, a drive shaft, a first gear and a second gear, the motor is mounted on the top cover, the top cover has a receiving groove, the drive shaft is fixed to the movable end of the motor, the first gear is mounted on the drive shaft and rotates in the receiving groove, the second gear is mounted on the rotating shaft and meshes with the first gear.

[0017] The principle and effect of this technical solution: The motor drives the drive shaft to rotate, which in turn drives the first gear to rotate. The first gear meshes with the second gear, which in turn drives the shaft to rotate synchronously. Compared with the method of directly connecting the shaft to the motor, in this method, the top of the shaft is open and can be connected to the liquid supply pipe. Moreover, with the setting of the sealing component, the shaft can rotate independently relative to the liquid supply pipe, thus avoiding the situation where the liquid supply pipe gets tangled when rotating synchronously with the shaft.

[0018] The present invention is further configured such that: the sealing assembly includes a sealing cover, a sealing bearing, and a shaft seal; the sealing cover is installed on the top cover; the shaft seal is fixed to the top of the inner side of the sealing cover; the sealing bearing is fixed to the top of the rotating shaft and abuts against the inner wall of the sealing cover; the bottom surface of the shaft seal abuts against the top surface of the sealing bearing; and the liquid supply pipe is inserted and fixed on the sealing cover and passes through the shaft seal.

[0019] The principle and effect of this technical solution are as follows: By installing the sealing cap on the top cover, the sealing cap will not rotate synchronously with the rotating shaft, which means that the liquid supply pipe will not rotate synchronously with the rotating shaft, thus avoiding the situation of the liquid supply pipe getting tangled. Through the setting of the sealed bearing, the rotating shaft can rotate relative to the sealing cap while ensuring a high degree of concentricity (positional stability). Furthermore, through the setting of the shaft seal, the liquid in the liquid supply channel cannot overflow from the connection between the rotating shaft and the sealing cap, thus avoiding the corrosion of the external environment by the acid and alkali additives.

[0020] The present invention is further configured such that: the sealing assembly also includes an extension plate and a mounting bolt, the extension plate is fixed to the outer wall of the sealing cover and abuts against the top cover, the mounting bolt is slidably inserted into the extension plate, and the end of the mounting bolt is threaded into the top cover.

[0021] The principle and effect of this technical solution: By setting the extension plate and mounting bolts, the sealing cover can be fixed on the top cover, thereby avoiding the rotating shaft from driving the sealing cover to rotate synchronously. Moreover, the sealing cover can be quickly disassembled and assembled by rotating the mounting bolts, which facilitates the replacement and maintenance of parts.

[0022] The present invention is further configured such that: the stirring mechanism also includes a mounting block and a connecting bolt, the outer wall of the rotating shaft has a protrusion, the mounting block is slidably fitted on the rotating shaft, and the mounting block has a recess that matches the protrusion, the stirring blade is fixed on the outer wall of the mounting block, the connecting bolt is slidably inserted into the mounting block, and the end of the connecting bolt is threaded into the rotating shaft.

[0023] The principle and effect of this technical solution: By setting the mounting block and connecting bolts, the stirring blade can be detached from the rotating shaft, and this can be done by rotating the connecting bolts. Subsequent cleaning, maintenance and replacement are more convenient. The setting of protrusions and recesses makes it easier to position the mounting block relative to the rotating shaft, which facilitates the installation of the connecting bolts.

[0024] The present invention is further configured such that: multiple stirring blades and one-way valves are respectively arranged at intervals along the axial direction of the rotating shaft.

[0025] The principle and effect of this technical solution: Through the setting of multiple sets, the stirring blades can play a stirring and mixing function on the pharmaceutical materials at different heights in the tank body. The setting of one-way valves at different heights allows acid and alkali additives to flow out from the one-way valves at different heights, thereby enabling the pH adjustment solution to be injected into the tank body more evenly, thereby improving the stirring efficiency and enabling the pH value in the tank body to reach equilibrium more quickly.

[0026] The present invention is further configured such that the detection end of the pH sensor is located at the lower end of the inner side of the tank body.

[0027] The principle and effect of this technical solution: By placing the detection end of the pH sensor at the lower end of the inner side of the can body, the pH sensor can play a detection role even when there is a small amount of medicine material in the can body. This avoids the problem of the pH sensor being unable to detect due to a small amount of medicine material in the can body. Attached Figure Description
