Description

Technical Field

[0001] This utility model relates to the field of waste liquid collector technology, and in particular to a waste liquid collector for biopharmaceutical production. Background Technology

[0002] Biopharmaceutical wastewater refers to wastewater with complex composition, high pollutant concentration, and high treatment difficulty generated during the production process. Waste liquids in reagent tubes or kits in the laboratory need to be collected uniformly through waste liquid collectors for subsequent centralized treatment.

[0003] The waste liquid collector mainly consists of a corrosion-resistant collection tank, a suction pipe, a sealing cap, and a base. When using it, the suction pipe must be connected to the equipment's drain port or the waste liquid must be manually poured out to ensure that different types of waste liquid are collected in their respective tanks and clearly labeled. The collection process must be kept sealed and temporarily stored in a safe location. When the liquid level is close to full, the inlet should be closed, and the waste should be transferred in a sealed manner by professionals in accordance with hazardous waste regulations, and finally handed over to a professional organization for disposal.

[0004] In pharmaceutical manufacturing processes, chemical reactions within reagent tubes often produce flocculated or solid byproducts. Existing waste liquid collectors indiscriminately collect these solid or semi-solid substances along with liquid waste liquid during operation. This mixture then enters the chemical oxidation process, posing a significant safety hazard. Because the properties of solid-liquid mixtures are complex and unpredictable in an oxidizing environment, they are highly susceptible to localized overheating and spontaneous combustion, or the generation of large amounts of gas due to their unstable reaction characteristics, leading to a sudden increase in pressure and the risk of explosion. This poses a serious threat to operational safety and equipment integrity. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing waste liquid collectors collect solid or semi-solid substances together with waste liquid, thus posing a safety hazard. Therefore, this invention proposes a waste liquid collector for biopharmaceutical production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A waste liquid collector for biopharmaceutical production includes a base and a collection tank movably mounted on the base. The collection tank is equipped with a liquid suction component. The collector also includes a separation plate slidably mounted on the collection tank, the separation plate having crests and troughs. The separation plate has permeation holes arranged in a ring on the separation plate and filter paper is provided on the separation plate. When the waste liquid passes through the filter paper, the filter paper separates the solids in the waste liquid. An mounting component is fixedly mounted on the separation plate, the mounting component being arranged in a ring on the separation plate.

[0007] To facilitate the installation or removal of the separation plate, preferably, the mounting component includes a limiting block fixedly installed on the outer cylindrical surface of the separation plate, and limiting grooves arranged in a ring inside the collection tank, with the limiting block slidably installed in the limiting grooves. When the limiting block moves, the separation plate can be installed or removed inside the collection tank.

[0008] To avoid direct contact with the separation plate during installation or removal, the separation plate is further provided with positioning blocks arranged in a ring, and the positioning blocks are installed above the limiting blocks, with the ends of the positioning blocks extending horizontally towards the inside of the separation plate.

[0009] To facilitate the collection of waste liquid, preferably, the liquid suction component includes a lid that is rotatably mounted on the collection tank. The lid has an inlet and an outlet, both of which are connected to the collection tank. An outlet pipe is fixedly installed on the outlet, and the outlet end of the outlet pipe is connected to a negative pressure fan on the base.

[0010] To improve the service life of the separation plate, preferably, the separation plate is mainly made of corrosion-resistant material.

[0011] To prevent the permeation holes from becoming completely blocked, preferably, the separation plate is configured as an annular plate, and the separation plate has a "W" shaped cross section.

[0012] Compared with the prior art, this utility model provides a waste liquid collector for biopharmaceutical production, which has the following beneficial effects: 1. This waste liquid collector for biopharmaceutical production, through the use of a separation plate in conjunction with filter paper, can intercept solids in the waste liquid, achieving solid-liquid separation. This avoids the phenomenon of local overheating or spontaneous combustion of the mixture in an oxidizing environment due to the simultaneous collection of solids and liquids, effectively improving the safety of this application during use. On the other hand, the separation plate has peaks and troughs, so that when the solid-liquid mixture passes through the separation plate, the waste liquid preferentially passes through the troughs. When the permeation holes in the troughs become blocked, the waste liquid level rises, and then the waste liquid flows out through the permeation holes at the peaks. This effectively avoids the problem of separation failure caused by complete blockage of conventional separation plates, effectively reducing the number of times the separation plate needs to be cleaned, thereby improving the performance of the separation plate.

[0013] 2. This waste liquid collector for biopharmaceutical production uses a limiting groove and a limiting block to facilitate the installation and disassembly of the separation plate, thereby making it easier to clean the separation plate. At the same time, the positioning block can prevent operators from directly contacting the separation plate, improving the safety of the separation plate during installation and disassembly.

[0014] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model utilizes a separation plate and filter paper to effectively separate the solid and liquid in a solid-liquid mixture, thereby avoiding the simultaneous collection of solid or semi-solid substances and liquids, which could lead to local overheating or spontaneous combustion of the substances in an oxidizing environment, thus improving the safety of the collector during use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Example: Reference Figures 1-4A waste liquid collector for biopharmaceutical production includes a base 1 and a collection tank 2 movably mounted on the base 1. The collection tank 2 is equipped with a liquid suction component. The collector also includes a separation plate 5 slidably mounted on the collection tank 2. The separation plate 5 is annular and has a "W"-shaped cross-section, with peaks and troughs at its highest and lowest points. When waste liquid passes through the separation plate 5, it preferentially flows from the troughs, where solid or semi-solid substances are intercepted. When the troughs become blocked, the waste liquid level rises, thus gradually shifting the solid-liquid separation zone upwards, effectively extending the solid-liquid separation time during waste liquid collection. The liquid separation effect avoids the problem of rapid clogging caused by the planar shape of the conventional separation plate 5, effectively reducing the number of times the separation plate 5 needs to be cleaned and making it convenient to use. The separation plate 5 has permeation holes 6 arranged in a ring and filter paper 9 is provided on the separation plate 5. When the waste liquid passes through the filter paper 9, the filter paper 9 separates the solids in the waste liquid, thereby avoiding the problem of solid or semi-solid substances being collected together with the waste liquid into the collection tank 2, which could lead to local overheating or spontaneous combustion in the subsequent oxidation environment, thus improving the safety of this application during use; the separation plate 5 is fixedly installed with mounting parts, which are arranged in a ring on the separation plate 5.

[0020] Specifically, by using the separation plate 5 in conjunction with the filter paper 9, the solids in the waste liquid can be intercepted, achieving solid-liquid separation. This avoids the simultaneous collection of solids and liquids, which could lead to localized overheating or spontaneous combustion of the mixture in an oxidizing environment, effectively improving the safety of the application. On the other hand, the separation plate 5 has peaks and troughs, allowing the waste liquid to preferentially pass through the troughs when the solid-liquid mixture passes through the separation plate 5. When the permeation holes 6 at the troughs become blocked, the waste liquid level rises, allowing it to flow out through the permeation holes 6 at the peaks. This effectively avoids the problem of separation plate 5 becoming completely blocked, thus reducing the frequency of cleaning the separation plate 5 and improving its performance.

[0021] The mounting components include a limiting block 8 fixedly mounted on the outer cylindrical surface of the separating plate 5. A limiting groove 21 is arranged in a ring inside the collecting tank 2, and the limiting block 8 is slidably mounted within the limiting groove 21. When the limiting block 8 moves, the separating plate 5 can be installed or removed from the collecting tank 2. Sliding the limiting block 8 upwards removes the separating plate 5, and vice versa, it installs the separating plate 5. Simultaneously, the limiting groove 21 prevents the separating plate 5 from rotating horizontally during use, improving its stability. Positioning blocks 7 are arranged in a ring on the separating plate 5, mounted above the limiting block 8. The ends of the positioning blocks 7 extend horizontally towards the inner side of the separating plate 5. The positioning blocks 7 prevent operators from directly contacting the surface of the separating plate 5 during installation or removal, thus improving safety and preventing injury from direct contact with corrosive substances.

[0022] Specifically, the limiting groove 21 and the limiting block 8 work together to facilitate the installation and disassembly of the separation plate 5, thereby making it easier to clean the separation plate 5. At the same time, the positioning block 7 can prevent operators from directly contacting the separation plate 5, improving the safety of the separation plate 5 during installation and disassembly.

[0023] The liquid suction device includes a lid 3 that is rotatably mounted on the collection tank 2. The lid 3 has an inlet and an outlet, both of which are connected to the collection tank 2. An outlet pipe 4 is fixedly installed on the outlet, and the outlet end of the outlet pipe 4 is connected to a negative pressure fan on the base 1. By connecting the inlet to an external inlet pipe, a negative pressure is formed inside the collection tank 2 after the negative pressure fan is started, and the waste liquid is sucked into the collection tank 2 through the inlet end of the inlet pipe. This avoids direct contact between the operator and the reagent tube or reagent kit. At the same time, the bottom ends of the inlet and outlet are on the same plane, and an absorbent paper is installed inside the outlet to effectively prevent the outlet pipe 4 from drawing out some water mist or atomized waste liquid, thus facilitating the operator's use.

[0024] The separation plate 5 is mainly made of corrosion-resistant materials. In this application, the material of the separation plate 5 is polypropylene. Polypropylene has the characteristics of acid and alkali resistance, thereby improving the service life of the separation plate 5. At the same time, polypropylene is inexpensive, which effectively reduces the manufacturing cost of the equipment.

[0025] In this invention, the inlet pipe is first inserted into the inlet. Then, by activating the negative pressure fan inside the base 1, air is expelled from the collection tank 2 through the exhaust pipe 4, creating negative pressure inside the collection tank 2. Waste liquid from the reagent tube or kit is then drawn into the collection tank 2 through the inlet pipe. The solid-liquid mixture first contacts the filter paper 9, and the filter paper 9 then permeates, trapping solid or semi-solid substances at the troughs. The separated liquid flows out through the permeation holes 6 and enters the bottom of the collection tank 2, thus completing the solid-liquid separation of the waste liquid. When the troughs of the separation plate 5 become blocked, the waste liquid level rises, allowing the solid-liquid mixture to continue separating through the permeation holes 6 near the crests. This effectively extends the service life of the separation plate 5 and reduces the frequency of cleaning. Furthermore, when cleaning the separation plate 5 is required, simply remove the lid 3 and then pinch the positioning block 7 to lift it upwards to remove the separation plate 5 and filter paper 9, facilitating cleaning of the separation plate 5 or replacement of the filter paper 9.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
