Description

Technical Field

[0001] This utility model relates to the field of aqueous preparation technology, and in particular to a quantitative feeding device for aqueous preparation. Background Technology

[0002] The quantitative feeding device for aqueous preparation is mainly used in the fields of liquid pharmaceuticals, chemical products and food production. It involves an automated precision control system that accurately adds raw materials according to a set ratio. This device not only improves production efficiency and reduces human error, but also ensures the consistency and stability of product quality.

[0003] However, in actual use, the following shortcomings still exist: existing quantitative feeding devices for aqueous preparation cannot achieve precise quantitative feeding of aqueous raw materials, ensure flowability, and improve feeding efficiency and accuracy. In terms of product quality, deviations in raw material ratios can lead to excessive or insufficient content of effective ingredients, causing safety hazards. Large fluctuations in concentration and pH between batches may also cause impurities and air bubbles to grow due to raw material retention, reducing the product qualification rate. In terms of production efficiency, the extended feeding cycle leads to a decrease in production capacity. Poor flowability can easily cause pipeline blockage, requiring frequent shutdowns for cleaning. At the same time, manual monitoring and verification are required, further slowing down the process. In terms of cost, excessive feeding and retention cause waste of raw materials, and significantly increase labor, energy consumption, and equipment maintenance costs. In terms of compliance, it cannot meet the industry's mandatory requirements for feeding accuracy, and products may be judged as unqualified and face regulatory penalties. It is also difficult to achieve compliance traceability in the production process.

[0004] Therefore, this utility model proposes a quantitative feeding device for the preparation of aqueous solutions to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a quantitative feeding device for the preparation of aqueous solutions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quantitative feeding device for preparing aqueous solutions, comprising a tank, and further comprising:

[0007] A metering assembly includes a metering tube disposed at the bottom of the tank, a guide groove being provided inside the metering tube, a hydraulic push rod being installed on one side of the top of the metering tube, a piston being connected to the output end of the hydraulic push rod, the piston being slidably connected inside the guide groove, a fixed tube being connected to the side of the guide groove near the bottom, a movable block being slidably connected inside the fixed tube, a stop block being connected to the bottom of the movable block, and a telescopic spring being provided on the movable block;

[0008] A stirring assembly, comprising a servo motor mounted on a tank, the output end of which is connected to a rotating shaft, and a stirring paddle connected to the rotating shaft.

[0009] Furthermore, one end of the telescopic spring is connected to the fixed tube, and the other end of the telescopic spring is connected to the moving block.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: the two ends of the telescopic spring are respectively connected to the fixed tube and the moving block. When the raw material squeezes the moving block, the telescopic spring is compressed and stores energy. When the material discharge ends and the pressure disappears, the telescopic spring elastically resets and pushes the moving block to move upward, thereby driving the stop block to close the fixed tube channel, realizing automatic opening and closing and ensuring the sealing of quantitative feeding.

[0011] Furthermore, a discharge pipe is provided at the bottom of the tank.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the discharge pipe at the bottom of the tank is the raw material output channel, through which the stirred water raw material is transported to the metering component. Its pipe diameter is adapted to the flowability of the raw material, ensuring that the raw material enters the metering pipe stably, and providing continuous supply for subsequent metering.

[0013] Furthermore, a connector is provided at the bottom of the tank, and the discharge pipe is disposed inside the connector.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the connector at the bottom of the tank is used to fix the discharge pipe, and the discharge pipe is connected to the tank through structural cooperation, which enhances the connection sealing, prevents raw material leakage, and facilitates disassembly and maintenance, ensuring the stability of the material conveying path.

[0015] Furthermore, a lid is connected to the top of the tank, and the servo motor is mounted on the lid.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the tank cover at the top of the tank seals the tank, the servo motor is installed on it, and the output end of the servo motor passes through the tank cover and connects to the rotating shaft to form a stirring power transmission structure. The tank cover not only ensures the airtightness of the tank, but also provides a stable installation foundation for the stirring components.

[0017] Furthermore, a screw cap is threaded onto the top side of the can lid.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the screw cap on the top of the can lid is connected by a thread, which can be opened to add raw materials into the can, and when closed, it forms a seal to prevent the raw materials from getting damp or impurities from entering. The threaded design makes operation convenient, ensures the airtightness of the can, and facilitates material replenishment.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the aqueous raw material in the tank is processed by the stirring assembly. The servo motor drives the rotating shaft to rotate, which in turn drives the stirring paddle to stir the raw material, preventing agglomeration and ensuring fluidity. After the raw material enters the metering tube of the metering assembly, the hydraulic push rod pushes the piston to slide in the guide groove, squeezing the raw material to move towards the fixed tube. The pressure of the raw material causes the moving block to compress the telescopic spring, which drives the stop block to move down, opening the channel of the fixed tube. The raw material is discharged in a metered amount according to the piston push. After the discharge is completed, the hydraulic push rod pushes back, the telescopic spring resets, and the stop block closes the channel, completing one metered feeding. This invention achieves precise metered feeding of aqueous raw materials, ensuring fluidity and improving feeding efficiency and accuracy. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-5 As shown, this embodiment provides a technical solution: a quantitative feeding device for preparing an aqueous solution, including a tank 1, and further comprising:

[0032] The metering component 2 includes a metering tube 21 disposed at the bottom of the tank body 1. A guide groove 22 is provided inside the metering tube 21. A hydraulic push rod 23 is installed on one side of the top of the metering tube 21. A piston 24 is connected to the output end of the hydraulic push rod 23. The piston 24 is slidably connected inside the guide groove 22. A fixed tube 25 is connected to the side of the guide groove 22 near the bottom. A moving block 26 is slidably connected inside the fixed tube 25. A stop block 27 is connected to the bottom of the moving block 26. A telescopic spring 28 is provided on the moving block 26.

[0033] The mixing assembly 3 includes a servo motor 34 mounted on the tank 1. The output end of the servo motor 34 is connected to a rotating shaft 35, and a stirring paddle 36 is connected to the rotating shaft 35. The aqueous raw material in the tank 1 is processed by the mixing assembly 3. The servo motor 34 drives the rotating shaft 35 to rotate, which in turn drives the stirring paddle 36 to stir the raw material, preventing agglomeration and ensuring fluidity. After the raw material enters the metering tube 21 of the metering assembly 2, the hydraulic push rod 23 pushes the piston 24 to slide in the guide groove 22, squeezing the raw material to move towards the fixed tube 25. The raw material pressure causes the moving block 26 to compress the telescopic spring 28, which drives the stop block 27 to move down, opening the channel of the fixed tube 25. The raw material is discharged in a metered amount according to the amount pushed by the piston 24. After the discharge is completed, the hydraulic push rod 23 pushes back, the telescopic spring 28 resets, and the stop block 27 closes the channel, completing one metered feeding. This achieves precise metered feeding of the aqueous raw material, ensuring fluidity and improving feeding efficiency and accuracy.

[0034] like Figure 3 As shown, one end of the telescopic spring 28 is connected to the fixed tube 25, and the other end of the telescopic spring 28 is connected to the moving block 26. The two ends of the telescopic spring 28 are respectively connected to the fixed tube 25 and the moving block 26. When the raw material squeezes the moving block 26, the telescopic spring 28 is compressed and stores energy. When the material discharge ends, the pressure disappears, and the telescopic spring 28 elastically resets and pushes the moving block 26 to move upward, which drives the stop block 27 to close the channel of the fixed tube 25, realizing automatic opening and closing and ensuring the sealing of quantitative feeding.

[0035] like Figure 1 as well as Figures 4-5As shown, a discharge pipe 31 is provided at the bottom of the tank 1. The discharge pipe 31 at the bottom of the tank 1 is the raw material output channel. The stirred liquid raw material is transported to the metering component 2 through this pipe. Its pipe diameter is adapted to the flowability of the raw material to ensure that the raw material enters the metering pipe 21 stably, providing a continuous supply for subsequent metering. A connector 32 is provided at the bottom of the tank 1, and the discharge pipe 31 is placed in the connector 32. The connector 32 at the bottom of the tank 1 is used to fix the discharge pipe 31. Through structural cooperation, the discharge pipe 31 is connected to the tank 1 to enhance the connection sealing and prevent raw material leakage. At the same time, it is convenient to disassemble and maintain, and ensures the stability of the material conveying path. The top of the tank 1... A can lid 33 is connected to the can lid 33, and a servo motor 34 is installed on the can lid 33. The can lid 33 seals the can body 1 at the top of the can body 1. The servo motor 34 is installed on it, and the output end of the servo motor 34 passes through the can lid 33 and connects to the rotating shaft 35 to form a stirring power transmission structure. The can lid 33 not only ensures the airtightness of the can body 1, but also provides a stable installation base for the stirring component 3. A screw cap 37 is threadedly connected to one side of the top of the can lid 33. The screw cap 37 on the top of the can lid 33 is threadedly connected. When it is opened, raw materials can be added into the can body 1. When closed, it forms a seal to prevent the raw materials from getting damp or impurities from entering. The threaded design makes it easy to operate, ensures the airtightness of the can body 1, and facilitates the replenishment of materials.

[0036] Working principle:

[0037] like Figures 1-5As shown, firstly, when adding raw materials, unscrew the threaded cap 37 at the top of the tank lid 33 and inject the liquid raw material into the tank 1. After closing the cap 37, a sealed space is formed, which can prevent the raw material from getting damp or impurities from entering. The tank lid 33 not only seals the tank 1, but also provides an installation base for the stirring assembly 3. The output end of the servo motor 34 installed above it passes through the tank lid 33 and is connected to the rotating shaft 35 inside the tank 1, forming a stirring power transmission structure. After starting the equipment, the servo motor 34 drives the rotating shaft 35 to rotate, driving the stirring paddle 36 on the shaft to continuously stir the raw material in the tank 1, effectively breaking up the raw material lumps and ensuring its good fluidity, laying the foundation for subsequent quantitative conveying. The stirred raw material is conveyed to the quantitative assembly 2 through the discharge pipe 31 at the bottom of the tank 1. The discharge pipe 31 is fixed by the connector 32 at the bottom of the tank 1 to ensure a tight connection with the tank 1 and avoid... To prevent raw material leakage while ensuring continuous supply, the quantitative feeding process begins after the raw material enters the guide trough 22 of the quantitative tube 21. The hydraulic push rod 23 pushes the piston 24 to slide within the guide trough 22, squeezing the raw material towards the fixed tube 25. When the raw material pressure acts on the moving block 26 within the fixed tube 25, the moving block 26 compresses the extension springs 28 connected to the fixed tube 25 and itself at both ends, causing the bottom stop block 27 to move downward, opening the channel of the fixed tube 25. The raw material is discharged from the channel according to the amount pushed by the piston 24, achieving quantitative output. After the discharge is completed, the hydraulic push rod 23 pushes back, the extension spring 28 releases its stored energy and elastically resets, pushing the moving block 26 upward, and the stop block 27 closes the channel of the fixed tube 25, completing one quantitative feeding cycle. Through the repetitive operation of the above process, the device can continuously achieve precise and efficient quantitative feeding of aqueous raw materials.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
