Description

Technical Field

[0001] This utility model relates to the field of concentration tank technology, and in particular to a concentration tank with multi-stage feed inlets. Background Technology

[0002] Concentration tanks, also known as preparation tanks, mixing tanks, or blending tanks, are key equipment used in the pharmaceutical, food, and chemical industries for the preparation and storage of liquid materials, playing a particularly crucial role in the concentration and dilution processes of injectable drugs and traditional Chinese medicine preparations.

[0003] In existing technologies, conventional concentration tanks in industries such as pharmaceuticals and food (e.g., pharmaceutical GMP production lines) mostly employ a single top inlet to facilitate cleaning validation (CIP / SIP) and ensure sealing to prevent cross-contamination. Concentration tanks typically have a single inlet at the top through which all raw materials enter. This fixed inlet position and single fluid circulation path necessitate prolonged agitation by the stirring components to ensure uniform mixing of the raw materials, thus reducing preparation efficiency. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a concentration tank with multi-stage feed inlets to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a concentration tank with multi-stage feed inlets, including a tank body. A stirring shaft is rotatably connected inside the tank body. A drive assembly capable of driving the stirring shaft to rotate is provided on the tank body. A discharge port is provided at the bottom of the tank body. A main feed inlet and a secondary feed inlet are arranged on the tank body. A material cavity is opened inside the stirring shaft. A collar is fixedly connected to the secondary feed inlet through a pipe. The collar is sleeved on the outside of the stirring shaft, and the opening between the stirring shaft and the collar allows the secondary feed inlet to communicate with the material cavity. A conveying and stirring plate with a flow cavity inside is fixedly connected to the stirring shaft. A plurality of material drop holes are opened on the bottom surface of the conveying and stirring plate.

[0007] The above technical solution involves the following steps: When configuring the product, the main raw material is added to the tank through the main feed inlet. When adding other raw materials, the drive assembly is activated to rotate the stirring shaft, and the other raw materials are added through the auxiliary feed inlet. This portion of the raw material flows into the material chamber through a pipe, and then into the conveying and stirring plate. As the conveying and stirring plate rotates, it is sprinkled into the tank from different discharge holes.

[0008] Preferably, the shell of the tank has a double-layer structure with an internal cavity, and the tank is provided with an inlet pipe and an outlet pipe that communicate with the cavity.

[0009] The above technical solution involves creating a cavity within the tank shell, allowing users to introduce hot steam, hot water, or other fluids into the cavity via a feed pipe as needed, thus aiding in the stability control of the tank and enhancing its applicability.

[0010] Preferably, both the main feed inlet and the auxiliary feed inlet are equipped with lockable caps.

[0011] The above technical solution is adopted: the caps set on the main feed port and the auxiliary feed port can not only isolate external dust and impurities when not in use, but also seal them, reduce the exchange of internal and external temperatures, and help maintain the temperature inside the tank.

[0012] Preferably, in any of the above embodiments, the bottom of the conveying and mixing plate is provided with an installation frame at the material discharge hole, the installation frame is provided with a sealing ball, and the bottom of the installation frame is provided with a support net.

[0013] The above technical solution, with the sealing ball, support net and discharge hole forming a simple one-way valve structure, can prevent the raw materials in the tank from flowing back into the conveying and mixing plate.

[0014] Preferably, in any of the above schemes, the diameter of the plurality of material discharge holes increases as their distance from the stirring shaft increases.

[0015] The above technical solution is adopted: the diameter of the discharge hole varies with the distance from the center, so that the discharge hole near the center can only discharge a small amount of raw material, while the discharge hole at a distance can discharge a large amount of raw material. In addition, the centrifugal force generated by the rotation of the stirring shaft can also discharge raw material from the farthest discharge hole, making the raw material more evenly distributed.

[0016] Preferably, any of the above schemes has several secondary feed inlets that are evenly arranged along the height of the tank.

[0017] The above technical solution allows multiple secondary feed ports to provide separate feeding paths for various raw materials, enabling users to select different secondary feed ports for material addition as needed, making the application more flexible.

[0018] Preferably, in any of the above embodiments, a solid stirring plate is fixedly connected to the stirring shaft.

[0019] The above technical solution involves installing a regular stirring plate on the stirring shaft, so that the raw materials in areas where no clinker stirring plate is installed can also be stirred and mixed.

[0020] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0021] 1. This multi-stage feed tank, equipped with a stirring shaft, main feed inlet, secondary feed inlet, material chamber, collar, conveying and stirring plate, and discharge holes, allows for the addition of main raw materials to the tank through the main feed inlet during product preparation. When adding other raw materials, the drive assembly rotates the stirring shaft, allowing these materials to be added through the secondary feed inlet. These materials then flow through pipes into the material chamber and subsequently into the conveying and stirring plate. As the plate rotates, they are dispersed into the tank through various discharge holes. Other raw materials, while rotating, fall into the tank through multiple discharge holes, coming into contact with and mixing with the main raw materials. Combined with the stirring action of the stirring shaft and conveying and stirring plate, this ensures faster and more uniform mixing of the materials. Main raw materials and other raw materials can also be added simultaneously, allowing them to mix during the addition process, thus improving preparation efficiency.

[0022] 2. This concentration tank features multi-stage feed inlets and an internal cavity within the tank shell. Users can introduce hot steam, hot water, or other fluids through the feed pipe as needed to aid in controlling the stability within the tank, thus enhancing its versatility. The sealing ball, support mesh, and discharge holes form a simple one-way valve structure, preventing the raw material from flowing back into the conveying and mixing plate. The diameter of the discharge holes varies with distance from the center, ensuring that only a small amount of raw material flows out from the holes closer to the center, while larger volumes flow from the more distant holes. Combined with the centrifugal force generated by the rotating mixing shaft, even the furthest discharge holes receive material, resulting in more uniform material distribution.

[0023] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1-3 As shown, this utility model includes a tank body 1, a stirring shaft 2 rotatably connected inside the tank body 1, a drive assembly 3 that can drive the stirring shaft 2 to rotate on the tank body 1, a discharge port 4 at the bottom of the tank body 1, a main feed port 5 and a secondary feed port 6 arranged on the tank body 1; a material cavity 7 is opened inside the stirring shaft 2, a collar 8 is fixedly connected to the secondary feed port 6 through a pipe, the collar 8 is sleeved on the outside of the stirring shaft 2 and the opening between the stirring shaft 2 and the collar 8 allows the secondary feed port 6 to communicate with the material cavity 7, a conveying stirring plate 9 with a flow cavity inside is fixedly connected to the stirring shaft 2, and a plurality of discharge holes 10 are opened on the bottom surface of the conveying stirring plate 9.

[0032] When configuring the product, the main raw material is added to the tank 1 through the main feed port 5. When adding other raw materials, the drive assembly 3 is started to drive the stirring shaft 2 to rotate, and the other raw materials are added through the auxiliary feed port 6. This part of the raw material flows into the material chamber 7 through the pipeline, and then flows into the conveying and stirring plate 9. As the conveying and stirring plate 9 rotates, it is sprinkled into the tank 1 from different drop holes 10.

[0033] Example 1: The shell of tank 1 adopts a double-layer structure, with an internal receiving cavity. Tank 1 is provided with a feed pipe 11 and a discharge pipe 12 that communicate with the receiving cavity. Both the main feed port 5 and the auxiliary feed port 6 are provided with lockable caps.

[0034] Specifically: The shell of tank 1 has a receiving cavity, into which the user can introduce hot steam, hot water, or other fluids as needed through the feed pipe 11 to help control the stability inside tank 1, making it more versatile. The caps on the main feed port 5 and the auxiliary feed port 6 not only isolate external dust and impurities when not in use, but also seal them off to reduce internal and external temperature exchange, which helps maintain the temperature inside tank 1.

[0035] Example 2: A mounting frame 13 is provided at the bottom of the feeding and mixing plate 9 at the discharge hole 10. A sealing ball 15 is provided inside the mounting frame 13, and a support net 14 is provided at the bottom of the mounting frame 13. The diameter of the discharge holes 10 increases as the distance between them and the mixing shaft 2 increases.

[0036] Specifically, the sealing ball 15, together with the support net 14 and the discharge hole 10, forms a simple one-way valve structure, which can prevent the raw material in the tank 1 from flowing back into the conveying and mixing plate 9. The diameter of the discharge hole 10 varies with its distance from the center, so that the discharge hole 10 near the center can only discharge a small amount of raw material, while the discharge hole 10 at a distance can discharge a large amount of material. In addition, the centrifugal force generated by the rotation of the mixing shaft 2 ensures that raw material can also flow out of the farthest discharge hole 10, making the material distribution more uniform.

[0037] Example 3: There are several secondary feed inlets 6, which are evenly arranged along the height of the tank 1. A solid ordinary stirring plate is fixedly connected to the stirring shaft 2.

[0038] Specifically: Multiple auxiliary feed ports 6 can provide separate feeding paths for various raw materials, allowing users to select different auxiliary feed ports 6 to add materials as needed, making the use more flexible. Ordinary mixing plates are set on the mixing shaft 2, so that raw materials in areas without clinker mixing plates 9 can also be mixed.

[0039] The working principle of this utility model is as follows:

[0040] S1. Add the main raw material into tank 1 through the main feed inlet 5;

[0041] S2. When adding other raw materials, start the drive assembly 3 to drive the stirring shaft 2 to rotate, and add other raw materials through the auxiliary feed port 6. This part of the raw materials flows into the material chamber 7 through the pipe, and then into the conveying and stirring plate 9. As the conveying and stirring plate 9 rotates, it is sprinkled into the tank 1 from different drop holes 10.

[0042] S3. Other raw materials fall into the tank 1 from multiple discharge holes 10 during rotation, come into contact with and mix with the main raw materials. With the addition of the stirring shaft 2 and the conveying stirring plate 9, the raw materials can be mixed more quickly and evenly.

[0043] Compared with the prior art, the present invention has the following advantages:

[0044] 1. This multi-stage feed tank, equipped with a stirring shaft 2, main feed inlet 5, secondary feed inlet 6, material chamber 7, collar 8, conveying and stirring plate 9, and discharge holes 10, allows for the following process: During product preparation, the main raw material is added to the tank 1 through the main feed inlet 5. When adding other raw materials, the drive assembly 3 is activated, rotating the stirring shaft 2 and adding the other raw materials through the secondary feed inlet 6. This material flows through a pipe into the material chamber 7 and then into the conveying and stirring plate 9. As the conveying and stirring plate 9 rotates, it is sprinkled into the tank 1 through different discharge holes 10. Other raw materials, during rotation, fall into the tank 1 through multiple discharge holes 10, coming into contact with and mixing with the main raw material. Combined with the stirring action of the stirring shaft 2 and the conveying and stirring plate 9, this ensures faster and more uniform mixing of the raw materials. The main raw material and other raw materials can also be added simultaneously, allowing them to mix during the addition process, thus improving preparation efficiency.

[0045] 2. This concentration tank, equipped with multi-stage feed inlets, has a receiving cavity within the shell of tank 1. Users can introduce hot steam, hot water, or other fluids into this cavity via the feed pipe 11 as needed, assisting in controlling the stability within tank 1 and enhancing its applicability. The sealing ball 15, together with the support net 14 and the discharge hole 10, forms a simple one-way valve structure, preventing the raw material in tank 1 from flowing back into the conveying and mixing plate 9. The diameter of the discharge hole 10 varies with its distance from the center, ensuring that only a small amount of raw material flows out from the discharge hole 10 near the center, while the discharge holes 10 further away can discharge a large volume of material. Combined with the centrifugal force generated by the rotation of the mixing shaft 2, even the furthest discharge hole 10 can discharge raw material, resulting in more uniform material distribution.
