Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifuge tube waste liquid recovery, and in particular to a structure for recovering waste liquid from centrifuge tubes used in laboratory centrifuges. Background Technology
[0002] Centrifuges are a common piece of equipment in laboratories used to separate substances of different densities. When using a centrifuge, centrifuge tubes are usually used to load the samples to be separated. However, after the centrifugation process is completed, some waste liquid often remains in the centrifuge tubes, which needs to be collected and treated.
[0003] Currently, when recovering waste liquid from centrifuge tubes, the waste liquid is usually poured into a waste liquid collection container. However, the current collection container is difficult to adjust in terms of the height of the waste liquid collected, resulting in poor flexibility when used with laboratory benches of different heights. Furthermore, it cannot filter the collected waste liquid, and impurities in the waste liquid will affect subsequent treatment. Therefore, we propose a waste liquid recovery structure for laboratory centrifuges to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a waste liquid recovery structure for centrifuge tubes in laboratory centrifuges, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A waste liquid recovery structure for centrifuge tubes in a laboratory centrifuge includes a collection box, a lifting component above the collection box, a flow guide above the lifting component, a recovery mesh plate fixedly installed at the top of the flow guide, a filter assembly below the flow guide, a connecting pipe below the filter assembly, and a telescopic hose fixedly connected to the bottom end of the connecting pipe, the bottom end of the telescopic hose being fixedly connected to the upper surface of the collection box.
[0007] In a further embodiment, the lifting component includes a support cover fixedly installed on the upper surface of the collection box, a lifting slide plate slidably connected to the inner wall of the support cover, an electric cylinder fixedly installed on the upper surface of the collection box, the telescopic end of the electric cylinder being fixedly installed with the bottom end of the lifting slide plate, and the upper surface of the lifting slide plate being fixedly installed with the outer surface of the guide shroud.
[0008] In a further embodiment, the filter assembly includes a filter cover, the inner ring of which is threadedly connected to a filter screen plate. A connecting pipe is provided above the filter screen plate. The top end of the connecting pipe is fixedly connected to the bottom end of the flow guide cover. Limiting rings are fixedly connected to the outer surface of the connecting pipe and the outer surface of the connecting pipe. Threaded connecting covers are fitted onto the outer surfaces of the connecting pipe and the connecting pipe. The inner rings of the two threaded connecting covers are threadedly connected to the outer surface of the filter cover.
[0009] In a further embodiment, a discharge pipe is fixedly connected to the outer surface of the collection box, a control valve is fixedly connected to the outer surface of the discharge pipe, and a transparent observation plate is fixedly embedded in the outer surface of the collection box.
[0010] In a further embodiment, a controller is fixedly mounted on the outer surface of the lifting component, and the controller is electrically connected to the electric cylinder via a wire.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention utilizes an electric cylinder to drive a lifting slide plate within a support cover, enabling the overall height of the guide cover and the collection screen to be raised or lowered. This allows for flexible adjustment of the collection height, easily adapting to laboratory benches of varying heights and enhancing the flexibility and convenience of use. Through the filter assembly, waste liquid can flow from the guide cover through a connecting pipe into the filter cover. The filter screen within the filter cover effectively intercepts and filters solid impurities from the waste liquid, reducing interference from these impurities in subsequent processing steps and improving the efficiency and quality of waste liquid treatment.

[0021] Please see Figures 1-4This utility model discloses a waste liquid recovery structure for centrifuge tubes in a laboratory centrifuge, comprising a collection box 1, a lifting component 2 above the collection box 1, a flow guide hood 3 above the lifting component 2, a recovery mesh plate 4 fixedly installed at the top of the flow guide hood 3, a filter assembly 5 below the flow guide hood 3, a connecting pipe 6 below the filter assembly 5, and a telescopic hose 7 fixedly connected to the bottom end of the connecting pipe 6. The bottom end of the telescopic hose 7 is fixedly connected to the upper surface of the collection box 1. The collection box 1 is used to store the recovered waste liquid, while the lifting component 2 can adjust the height of the flow guide hood 3 and the recovery mesh plate 4 to adapt to different usage scenarios. The filter assembly 5 can filter and purify the waste liquid, and the connecting pipe 6 and the telescopic hose 7 can serve as channels to transport the filtered waste liquid to the inside of the collection box 1 for storage.
[0022] In a further embodiment, the lifting component 2 includes a support cover 201 fixedly installed on the upper surface of the collection box 1. A lifting slide plate 203 is slidably connected to the inner wall of the support cover 201. An electric cylinder 202 is fixedly installed on the upper surface of the collection box 1. The telescopic end of the electric cylinder 202 is fixedly installed with the bottom end of the lifting slide plate 203. The upper surface of the lifting slide plate 203 is fixedly installed with the outer surface of the flow guide 3. Using the electric cylinder 202 as a power source, the lifting slide plate 203 can be telescopically driven to slide within the support cover 201, thereby achieving precise adjustment of the height of the flow guide 3 and enhancing the adaptability of the recycling structure to laboratory platforms of different heights.
[0023] In a further embodiment, the filter assembly 5 includes a filter cover 501, with a filter screen 504 threadedly connected to the inner ring of the filter cover 501. A connecting pipe 502 is provided above the filter screen 504, and the top end of the connecting pipe 502 is fixedly connected to the bottom end of the flow guide shroud 3. Limiting rings 503 are fixedly connected to the outer surface of the connecting pipe 502 and the outer surface of the connecting pipe 6. Threaded connecting covers 505 are fitted onto the outer surfaces of both the connecting pipe 502 and the connecting pipe 6, and the inner rings of the two threaded connecting covers 505 are connected to the outer surface of the filter cover 501. The threaded connection, through the cooperation of the filter cover 501 and the filter screen 504, can intercept solid impurities in the filtered waste liquid. The connecting pipe 502 is used to receive the waste liquid flowing out of the guide cover 3 and guide it into the filter cover 501. Through the cooperation of the limiting ring 503 and the threaded connection cover 505, a detachable connection structure can be formed, which is convenient for periodic disassembly and cleaning of the filter screen 504 to maintain the filtration effect. In addition, sealing gaskets are provided between the threaded connection cover 505, the filter cover 501 and the limiting ring 503 to prevent liquid leakage.
[0024] In a further embodiment, a discharge pipe 8 is fixedly connected to the outer surface of the collection box 1, and a control valve 9 is fixedly connected to the outer surface of the discharge pipe 8. A transparent observation plate 10 is fixedly embedded in the outer surface of the collection box 1, and a controller 11 is fixedly installed on the outer surface of the lifting component 2. The controller 11 is electrically connected to the electric cylinder 202 through a wire. Through the cooperation of the discharge pipe 8 and the control valve 9, the waste liquid stored in the collection box 1 can be conveniently discharged for subsequent processing. The transparent observation plate 10 allows the operator to intuitively view the amount of waste liquid stored in the collection box 1. The lifting operation control of the lifting component 2 can be realized through the controller 11.
[0025] The working principle of this utility model is as follows: First, the waste liquid from the centrifuge tube is poured onto the recovery screen plate 4. The waste liquid enters the guide hood 3 through the recovery screen plate 4, which guides the flow of the waste liquid. The waste liquid then passes through the filter assembly 5, the connecting pipe 6, and the telescopic hose 7, and finally flows into the collection box 1 for collection. When it is necessary to adjust the collection height, the operator starts the electric cylinder 202 through the controller 11, which drives the lifting slide plate 203 to slide on the inner wall of the support cover 201, thereby realizing the raising and lowering of the overall height of the guide hood 3 and the recovery screen plate 4. This allows the recovery structure to be adapted to laboratory tables of different heights. Moreover, during the waste liquid collection process, the waste liquid enters the filter cover 501 from the guide hood 3 through the connecting pipe 502. The filter screen plate 504 intercepts and filters the solid impurities in the waste liquid. The filtered waste liquid enters the collection box 1 for storage through the connecting pipe 6 and the telescopic hose 7. Then, the operator can check the collection status of the waste liquid in the collection box 1 through the transparent observation plate 10. When the waste liquid is full, the control valve 9 on the discharge pipe 8 is opened to discharge the waste liquid for subsequent processing.
