Description
Technical Field
[0001] This utility model relates to the field of waste liquid collection technology for biomedical production, specifically a waste liquid collector for biopharmaceutical production. Background Technology
[0002] With the rapid development of the biopharmaceutical industry, the amount of wastewater generated is also increasing. Biopharmaceutical wastewater is different from general industrial wastewater. It contains a large number of bioactive substances, unreacted raw materials, intermediate products, products and microbial metabolites. It is characterized by its variety, high concentration and high toxicity. This places high demands on wastewater collectors used in biopharmaceutical production to facilitate the subsequent treatment of these biopharmaceutical wastewaters.
[0003] Most existing waste liquid collectors used in biopharmaceutical production suffer from poor internal design, making waste liquid discharge extremely difficult after use. Large amounts of liquid remain inside, and manual drainage is not only cumbersome but also time-consuming and labor-intensive, severely reducing efficiency and significantly increasing operating costs. Furthermore, during waste liquid collection, filtration residues tightly clog the filter pores of the internal filter screen. These residues have a unique texture and are extremely difficult to clean. Neither tools nor attempts to remove the filter screen for deep cleaning are feasible, greatly hindering subsequent equipment maintenance and efficient operation. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a waste liquid collector for biopharmaceutical production, in order to solve the prominent problems of most waste liquid collectors used in biopharmaceutical production after use. Due to poor internal structure, waste liquid is difficult to discharge, a large amount of liquid remains, and manual drainage is cumbersome and time-consuming, which seriously reduces the efficiency of use and increases costs. When collecting waste liquid, filter residue will tightly block the filter screen pores. Its special texture makes it extremely difficult to clean, whether with the help of tools or by removing the filter screen for deep cleaning. This greatly hinders the subsequent maintenance of the equipment and affects the technical problems of efficient operation.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste liquid collector for biopharmaceutical production, comprising a main body, a main air supply pipe at the top of the main body, a plurality of branch jet pipes extending into the interior of the main body being connected to the main air supply pipe, an air gathering port being provided inside the branch jet pipe, a blocking block being movably connected inside the branch jet pipe, and the blocking block being elastically connected to the branch jet pipe by a second spring, a vibration mechanism being movably connected inside the main body, and a filter screen being provided inside the vibration mechanism.
[0006] By adopting the above technical solution, because the main body is equipped with a filter screen, smaller particles in the waste liquid will be filtered to the top of the filter screen, achieving a certain degree of solid-liquid separation, and ensuring that the liquid outlet at the bottom of the main body is sealed. When the collection is completed, the main body is sealed to prevent leakage of the internal waste liquid. When the waste liquid needs to be discharged after storage, the sealed liquid outlet at the bottom of the main body is opened, and the internal waste liquid will flow out to the outside for treatment along the liquid outlet. Then, it is ventilated by connecting the high-pressure air pipe to the main air supply pipe at the top of the main body. When the high-pressure gas inside the main air inlet pipe flows, it will generate a certain wind pressure, which will be dispersed along the multiple sets of branch jet pipes set at the bottom of the main air supply pipe. This allows the multiple sets of branch jet pipes to spray high-pressure air through the jet holes set inside the main body to clean the accumulated waste liquid inside the main body that cannot flow out naturally, so that it can be discharged from the liquid outlet opened at the bottom.
[0007] Furthermore, the vibration mechanism includes a squeezing block, a first spring, and a locking ring. The locking ring and the squeezing block are elastically connected by the first spring. The top of the main body has a liquid inlet, and the inside of the main body has a collection chamber that communicates with the liquid inlet.
[0008] By adopting the above technical solution, when the high-pressure air flows inside the branch jet pipe, the air-gathering port inside it will further compress the air, causing the internal air pressure to rise significantly. Subsequently, the high-pressure air is ejected from the bottom of the air-gathering port, pushing the blocking block downward under the action of the second spring. As the blocking block gradually moves downward, the distance between it and the air-gathering port increases, thus no longer blocking the air-gathering port.
[0009] Furthermore, a fixing member is provided on the outer side of the locking ring, a handle is provided on the top of the main body, a pin is provided on the outer side of the main body to cooperate with the fixing member, an air jet hole communicating with the collection chamber is opened inside the main body, a base is provided at the bottom of the main body, and a drain port is provided at the top of the main body.
[0010] By adopting the above technical solution, the elastic potential energy of the second spring is released, causing the blockage block to bounce back upwards, shortening the distance between it and the air collection port. This process is repeated. Through the reciprocating motion of the blockage block, the filter screen inside the main body generates high-frequency vibration. This vibration can effectively clean the particulate impurities stuck in the filter screen pores, providing convenience for subsequent manual cleaning.
[0011] In summary, this utility model has the following beneficial effects: By pumping waste liquid into the inlet at the top of the main body through a water pump, solid-liquid separation is achieved after filtration through a filter screen. The waste liquid is stored inside the main body. When discharged, the outlet at the bottom is opened, allowing the waste liquid to flow out. High-pressure gas enters the branch jet pipe through the main air supply pipe and is ejected from the jet nozzle, cleaning the residual waste liquid. Simultaneously, compressed air at the air collection port pushes the blockage block to reciprocate, causing the filter screen to vibrate at high frequency, cleaning impurities from the filter holes. The vibration mechanism controls the filter screen vibration through a squeezing block and a second spring. After cleaning, the filter screen and vibration mechanism are pulled out by the handle to remove particulate matter. This design achieves efficient waste liquid discharge and automatic filter screen cleaning, saving time and effort, improving efficiency, and making it easy to remove filter residue for subsequent cleaning.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0022] The embodiments of this utility model will be described below based on its overall structure.
[0023] A waste liquid collector for biopharmaceutical production, such as Figures 1-8 As shown, the system includes a main body 1, with a main air supply pipe 2 at the top. The main air supply pipe 2 is connected to multiple branch jet pipes 11 extending into the main body 1. Each branch jet pipe 11 has a converging port 13 inside and a blocking block 14 is movably connected inside. The blocking block 14 and the branch jet pipe 11 are elastically connected by a second spring 15. Because a filter screen 10 is installed inside the main body 1, smaller particles in the waste liquid are filtered to the top of the filter screen 10, achieving a certain degree of solid-liquid separation. This ensures that the liquid outlet at the bottom of the main body 1 is sealed. When collection is complete, the main body 1 is sealed to prevent leakage of the waste liquid inside. When the waste liquid needs to be discharged after storage, the sealed liquid outlet at the bottom of the main body 1 is opened, and the waste liquid inside will be discharged to the outside for treatment.
[0024] For example, a vibration mechanism 9 is movably connected inside the main body 1. A filter screen 10 is installed inside the vibration mechanism 9. The vibration mechanism 9 includes a squeezing block 901, a first spring 902, and a locking ring 903. The locking ring 903 and the squeezing block 901 are elastically connected by the first spring 902. A liquid inlet 4 is opened at the top of the main body 1. The main air supply pipe 2 is connected to the top of the main body 1 through an external high-pressure air pipe for ventilation. When the high-pressure gas inside the main air inlet flows, it generates a certain wind pressure. The air pressure is dispersed along the multiple branch jet pipes 11 set at the bottom of the main air supply pipe 2, so that the multiple branch jet pipes 11 can spray high-pressure air through the jet port 12 set inside the main body 1 to clean the accumulated waste liquid inside the main body 1 that cannot flow out naturally, so that it can be discharged from the liquid outlet opened at the bottom.
[0025] For example, the main body 1 has a collection chamber 8 connected to the liquid inlet 4 inside, a fixing member 5 is provided on the outside of the locking ring 903, a handle 3 is provided at the top of the main body 1, a pin 7 that cooperates with the fixing member 5 is provided on the outside of the main body 1, a jet nozzle 12 connected to the collection chamber 8 is provided inside the main body 1, a base 6 is provided at the bottom of the main body 1, and a drain port is provided at the top of the main body 1. When the high-pressure air inside the branch jet pipe 11 flows, the air gathering port 13 provided inside it will further compress the air, causing the internal air pressure to increase significantly. Subsequently, the high-pressure air flows out from the air gathering port 13. The bottom end of the nozzle is ejected, pushing the blocking block 14 downward under the action of the second spring 15. As the blocking block 14 gradually moves downward, the distance between it and the air collection port 13 increases, thus no longer blocking the air collection port 13. At this time, the elastic potential energy of the second spring 15 is released, causing the blocking block 14 to bounce back upward, shortening the distance between it and the air collection port 13. This process is repeated. Through the reciprocating motion of the blocking block 14, the filter screen 10 inside the main body 1 is driven to generate high-frequency vibration. This vibration can effectively clean the particulate impurities stuck in the filter holes of the filter screen 10, providing convenience for subsequent manual cleaning.
[0026] The working principle of this utility model is as follows: When in use, the waste liquid generated during production is pumped to the delivery pipeline by an external water pump by an external worker, and the delivery pipeline is inserted into the liquid inlet 4 opened at the top of the main body 1 for filling.
[0027] At this time, because the main body 1 is equipped with a filter screen 10, smaller particles in the waste liquid will be filtered to the top of the filter screen 10, achieving a certain degree of solid-liquid separation, and ensuring that the liquid outlet at the bottom of the main body 1 is sealed. When the collection is completed, the main body 1 is sealed to prevent the internal waste liquid from leaking. When the waste liquid needs to be discharged after storage, the liquid outlet sealed at the bottom of the main body 1 is opened, and the internal waste liquid will be discharged to the outside for treatment along the liquid outlet.
[0028] Then, the high-pressure air pipe is connected to the main air supply pipe 2 set at the top of the main body 1 through the external high-pressure air pipe for ventilation. When the high-pressure gas inside the main air inlet pipe flows, it will generate a certain wind pressure, which will be dispersed along the multiple sets of branch jet pipes 11 set at the bottom of the main air supply pipe 2. This allows the multiple sets of branch jet pipes 11 to spray high-pressure air through the jet port 12 set inside the main body 1 to clean the accumulated waste liquid inside the main body 1 that cannot flow out naturally, so that it can be discharged from the liquid outlet opened at the bottom.
[0029] When the high-pressure air flows inside the branch jet pipe 11, the air-gathering port 13 inside it further compresses the air, causing the internal air pressure to rise significantly. Then, the high-pressure air is ejected from the bottom of the air-gathering port 13, pushing the blockage block 14 downward under the action of the second spring 15. As the blockage block 14 gradually moves downward, the distance between it and the air-gathering port 13 increases, thus no longer blocking the air-gathering port 13. At this time, the elastic potential energy of the second spring 15 is released, causing the blockage block 14 to bounce back upward, shortening the distance between it and the air-gathering port 13. This process is repeated. Through the reciprocating motion of the blockage block 14, the filter screen 10 inside the main body 1 is driven to generate high-frequency vibration. This vibration can effectively clean the particulate impurities stuck in the filter holes of the filter screen 10, providing convenience for subsequent manual cleaning.
[0030] Specifically, the vibration mechanism 9 is also equipped with a squeezing block 901 that cooperates with the locking ring 903 and a second spring 15 to ensure that the vibration mechanism 9 can control the filter screen 10 to vibrate up and down. After cleaning, the staff on the outside can also manually pull the handle 3 to pull the vibration mechanism 9 and the filter screen 10 out to the outside and clean out the particulate impurities.
[0031] The above structure makes subsequent cleaning easier, with no large amount of liquid remaining. It eliminates the need for manual drainage, saving time and effort and improving efficiency. Furthermore, during the collection of waste liquid, the residue produced by filtration is shaken during internal cleaning, making it easier to remove and clean.
