Description

Technical Field

[0001] This utility model relates to the field of enzyme activity testing technology, specifically to a reactor for enzyme activity testing. Background Technology

[0002] An enzyme reactor is a device required for reactions using enzymes as catalysts. This equipment includes containers for free enzymes, immobilized enzymes, and immobilized cells, along with auxiliary facilities such as mixing, sampling, and detection equipment. The purpose of an enzyme reactor is to prepare specific products from given reactants at a controlled rate and at the lowest possible cost. Enzyme reactors operate under low temperature and low pressure conditions, resulting in relatively low energy consumption and production. Unlike fermentation reactors, they do not exhibit autocatalysis, i.e., continuous cell regeneration. Enzyme reactors are the reaction vessels required for in vitro reactions of free and immobilized enzymes. These reaction vessels not only control the various conditions required for the catalytic reaction but also regulate the rate of the catalytic reaction.

[0003] However, existing enzyme activity testing reactors do not allow enzymes to react at all locations during the enzyme reaction, resulting in insufficient mixing of the enzymes. Furthermore, it is inconvenient to take samples during the enzyme reaction to understand the extent of the reaction. Therefore, they do not meet current requirements. To address this, we propose an enzyme activity testing reactor. Utility Model Content

[0004] The purpose of this invention is to provide a reactor for enzyme activity testing, which solves the problems mentioned in the background art, such as the inability of enzymes to react at all locations during enzyme reaction, insufficient mixing effect of enzymes, and inconvenience in sampling to understand the degree of enzyme reaction during the enzyme reaction process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reactor for enzyme activity testing, comprising a main body, a cover plate at the upper end of the main body, a motor above the cover plate, liquid outlets uniformly arranged at the lower end of the main body, support columns uniformly arranged on the outer side of the main body, an inlet pipe on the upper surface of the support column, a connecting plate above the inlet pipe, an outlet head between the inlet pipe and the connecting plate, a base at the lower end of the support column, a connecting pipe located on the outer side of the support column at the lower end of the main body, and a sampling pipe above the connecting pipe;

[0006] A gear ring is provided on the inner side of the cover plate, a sun gear is provided on the inner side of the gear ring, planet gears are evenly arranged between the sun gear and the gear ring, a connecting rod is provided on the inner side of the planet gears, a drive shaft is provided on the inner side of the sun gear, a liquid storage tank is provided on the inner side of the connecting plate, a float plate is provided on the inner side of the liquid storage tank, a reaction chamber is provided on the inner side of the main body, scrapers are evenly arranged on the outer side of the lower end of the drive shaft located inside the reaction chamber, stirring rods are evenly arranged on the outer side of the connecting rod, a sampling groove is provided on the inner side of the connecting pipe, an adjusting rod is provided on the inner side of the sampling groove, a sealing plug is provided at one end of the adjusting rod, and a rubber ball is placed between the sampling pipe and the connecting pipe.

[0007] Preferably, the outer surface of the connecting plate is provided with an observation window, and the outer surface of the observation window is provided with scale lines.

[0008] Preferably, the inner surface of the support column is completely fitted with the outer surface of the main body, and the support column is fixed to the main body by welding.

[0009] Preferably, the planetary gear meshes with the gear ring and the drive shaft, and the meshing point is coated with lubricating oil.

[0010] Preferably, one end of the scraper is fully in contact with the outer surface of the drive shaft, and the scraper is fixed to the drive shaft by screws.

[0011] Preferably, the adjusting rod is connected to the connecting pipe by a thread, and one end of the adjusting rod is provided with anti-slip stripes.

[0012] Preferably, the lower end of the support column is completely fitted with the upper surface of the base, the support column and the base are fixed by welding, and a valve is provided on the inner side of the liquid outlet head.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a stirring rod, scraper, connecting rod and drive shaft set inside the reaction chamber. When the motor is turned on, the motor drives the planetary gear transmission, which makes the stirring rod inside the planetary gear rotate on its own and revolve around the sun gear at the same time. This increases the stirring effect of the stirring rod, which can make the enzyme in the reaction chamber react fully and improve the enzyme reaction effect. In addition, the scraper set at the lower end of the drive shaft can reduce the residue on the inner wall of the reaction chamber, making it convenient for the staff to clean the inner wall.

[0015] 2. During the reaction in the reaction chamber, this utility model allows the sealing plug to move inward by rotating the adjusting rod through the connecting pipe, sampling pipe, and sampling groove set inside the support column, so that the liquid flows into the sampling groove. At this time, the sampling pipe is pressed into the sampling groove for sampling. This allows for a clear understanding of the enzyme reaction, making it convenient for staff to make adjustments and improving the ease of use of the device. Attached Figure Description

[0024] Furthermore, the outer surface of the connecting plate 3 is provided with an observation window, and the outer surface of the observation window is provided with scale lines.

[0025] By adopting the above technical solution, it is easier for staff to observe the amount of liquid in the storage tank 16, thus improving the accuracy of the device.

[0026] Furthermore, the inner surface of the support column 6 is completely fitted with the outer surface of the main body 10, and the support column 6 and the main body 10 are fixed by welding.

[0027] By adopting the above technical solution, the robustness of the connection of the support column 6 is increased, and the supporting effect of the support column 6 is improved.

[0028] Furthermore, the planetary gear 12 meshes with the gear ring 11 and the drive shaft 15, and the meshing point is coated with lubricating oil.

[0029] By adopting the above technical solution, the smoothness of planetary gear transmission is increased, and the transmission effect of the device is improved.

At this time, the sampling pipe 7 is pressed into the sampling groove 23 for sampling. This allows for a clear understanding of the enzyme reaction, facilitating adjustments by staff and improving the ease of use of the device.
