Description

Technical Field

[0001] This invention relates to a device for quantitative addition of compound enzyme preparations, belonging to the field of enzyme preparation quantitative addition devices. Background Technology

[0002] In the production, experimentation, and application of compound enzyme preparations, precise quantitative addition is a core prerequisite for ensuring reaction efficiency and product quality stability. The catalytic activity of compound enzyme preparations is significantly dose-dependent; even slight deviations in the dosage can lead to large fluctuations in reaction efficiency or even abnormal product composition. However, the addition equipment widely used in the industry currently has significant shortcomings in its core performance, making it difficult to meet the practical needs of high efficiency, precision, and convenience.

[0003] In the quantitative operation stage, most equipment adopts a direct addition method. When the required scale needs to be reached, if the addition flow rate is not controlled in time, it is easy to add too much due to inertia, resulting in over-addition and affecting the accuracy of the reaction. On the other hand, if the addition amount is deliberately controlled at a small level to avoid over-addition, the addition process will take too long and reduce work efficiency. In the critical step of quantitative adjustment, most equipment can only achieve coarse-scale graded control, such as setting only 2-3 fixed flow rates, and cannot continuously fine-tune the flow rate according to experimental or production needs. It is difficult to match the precise requirements of different reaction systems for enzyme concentration. Although some equipment attempts to achieve adjustable functions, the adjustment structure either uses a simple friction positioning method, which is prone to slippage and loosening after long-term use, and the angle deviation is prone to occur during the adjustment process, resulting in a large deviation between the actual addition amount and the preset value. This precision deficiency may directly lead to incomplete reaction, decreased product qualification rate, and even batch-to-batch quality fluctuations in fields such as biocatalysis and food processing, causing significant economic losses to enterprises. Therefore, it is necessary to design a compound enzyme quantitative addition device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quantitative addition device for compound enzyme preparations to solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative addition device for a compound enzyme preparation, comprising: Retractable support columns are used to support the entire device; The adjustment assembly includes a movable sleeve, a connecting rod, and a mounting ring.

[0007] Furthermore, the material storage assembly includes a material cylinder, a flange, a conical hopper, and a threaded connecting pipe.

A flange is provided at the edge of the bottom of the material cylinder, and the flange is connected to the mounting plate by bolts. The bottom of the conical hopper is integrally connected to the threaded connecting pipe.

[0008] Furthermore, the added components include an adjusting knob, a discharge pipe, a protective outer cylinder, and an adjusting sleeve. The top of the discharge pipe is fitted with a threaded connector adapted to the threaded connecting pipe, and a set of discharge holes is provided on the side wall of the discharge pipe. The discharge hole set consists of multiple discharge holes distributed in a matrix. An adjusting sleeve is fitted on the outside of the discharge pipe, and an adjusting knob is integrally connected to the top of the adjusting sleeve. A protective outer cylinder is fitted on the outside of the adjusting sleeve, and the top of the protective outer cylinder is fixedly connected to the bottom of the adjusting knob. A funnel is integrally connected to the bottom of the protective outer cylinder, and a first control valve is provided on the funnel.

[0009] Furthermore, the inner surface of the adjusting knob is provided with multiple ratchet grooves at equal intervals, and the outer surface of the threaded connector is provided with ratchet teeth at equal intervals that are adapted to the ratchet grooves. The adjusting knob is rotatably connected to the discharge pipe, and the outer wall of the adjusting knob is provided with indicator lines.

[0010] Furthermore, the inner diameter of the adjusting sleeve matches the outer diameter of the discharge pipe, and three openings are equally spaced on the side wall of the adjusting sleeve at the position corresponding to the discharge hole group. Sealing strips are glued to the inner side of each of the three openings, and the width of each of the three openings is adapted to the width of the discharge hole group. The height of the three openings decreases sequentially, with the height of the largest opening being the same as the height of the discharge hole group, and the heights of the other two openings being two-thirds and one-third of the height of the discharge hole group, respectively.

[0011] Furthermore, an observation window is provided at the end of the insulation cylinder away from the connecting rod, and a heating wire is wound around the inner surface of the insulation cylinder, with an outlet at the bottom of the insulation cylinder.

[0012] Furthermore, one end of the metering cylinder is provided with a scale line, and the scale line corresponds to the position of the observation window. The central axis of the metering cylinder coincides with the central axis of the component added above it. The bottom of the metering cylinder is integrally connected with a filling tube, and the top of the metering cylinder is integrally connected with an anti-detachment edge.

[0014] The beneficial effects of this utility model are: 1. The addition component allows for rapid switching of different flow rates through the cooperation of three openings at different heights on the adjusting sleeve and the discharge port group. When approaching the desired scale, the flow rate can be easily reduced to avoid over-addition due to inertia; while in the initial stage, a larger flow rate can be used, significantly shortening the addition time. This balances the accuracy and efficiency of addition, eliminating the need for operators to make difficult trade-offs between the two. The addition component not only has three fixed flow rate levels with clear proportions (100%, 67%, 33%) to meet basic graded control requirements, but also allows for continuous fine-tuning of the flow rate by rotating the adjusting knob to misalign the opening and the discharge port group. This can precisely match the fine requirements of different reaction systems for enzyme concentration. At the same time, the ratchet groove on the inner surface of the adjusting knob and the ratchet teeth on the outer surface of the threaded connector replace the simple friction positioning method, effectively preventing slippage, loosening, and angle deviation after long-term use, significantly reducing the deviation between the actual addition amount and the preset value, and ensuring adjustment accuracy.

[0015] 2. The equipment's retractable support columns and adjustable components provide height adjustability, adapting to different operating scenarios and container heights, thus enhancing the equipment's versatility. Most components utilize threaded connections and bolt fixation, ensuring structural stability and easy disassembly and assembly, facilitating cleaning, maintenance, and component replacement. The heating wire in the insulation cylinder maintains material activity, and the integration of the observation window with the scale lines on the metering cylinder enhances operational visibility. The fitting structure between the adjusting sleeve and the discharge pipe, along with the sealing strip, reduces material leakage, while the anti-detachment edge of the metering cylinder improves safety, further enhancing the equipment's practicality and reliability.

[0022] Please see Figure 1 , Figure 4 and Figure 5 The added component 5 includes an adjusting knob 501, a discharge pipe fitting 502, a protective outer cylinder 503, and an adjusting sleeve 504. The top of the discharge pipe fitting 502 is equipped with a threaded connector 5021 adapted to the threaded connecting pipe 404, and a set of discharge holes 5023 is formed on the side wall of the discharge pipe fitting 502. The discharge hole set 5023 consists of multiple discharge holes distributed in a matrix.

The second fastening knob 204 is rotatably connected to the limiting plate 205. A limiting ridge matching the limiting ridge groove 1021 is provided on the end of the limiting plate 205 near the limiting ridge groove 1021. This matching design ensures smooth sliding of the movable sleeve 201 along the telescopic column 102. The second fastening knob 204 cooperates with the limiting plate 205, and the limiting ridge of the limiting plate 205 matches the limiting ridge groove 1021 of the telescopic column 102, firmly locking the position of the movable sleeve 201. This stabilizes the height of the mounting ring 203 and connected components, ensuring stability after position adjustment and improving operational reliability.
