Description

Technical Field

[0001] This utility model relates to the field of waste liquid treatment technology, and more specifically, it relates to a waste liquid temporary storage device. Background Technology

[0002] Cell section preparation is the process of preparing cell or tissue samples into thin slides for observation under a microscope. It is mainly divided into two categories: tissue sections and cell smears. The tissue sectioning process involves multiple complex steps such as dehydration, clearing, paraffin infiltration, embedding, and sectioning. The cell smearing process involves multiple complex steps such as smear preparation, drying, and staining. Both processes generate a large amount of toxic and harmful waste liquid, which must be centrally treated.

[0003] Traditional waste liquid collection uses a negative pressure cavity for unified recycling. After the experiment, the negative pressure cavity needs to be dismantled and emptied. For example, Chinese invention patent No. 202011459815.8, entitled "Automatic Staining Device for Biological Tissue Sample Sections," discloses a device including a fluid intermediate device, a fluid end device, a slide tray, and a slide tray holding device. The slide tray is used to hold the slides, and the slide tray is held by the slide tray holding device. The fluid intermediate device and the fluid end device are connected by a fluid pipeline. The fluid intermediate device distributes the externally input staining liquid to the fluid end device. The fluid end device has an outlet and a waste liquid recovery hole. The staining liquid is applied to the slides held by the slide tray through the outlet, and after staining the samples on the slides, it is recovered into a negative pressure chamber through the waste liquid recovery hole by negative pressure suction. This automated staining device improves the efficiency of sample staining, reduces labor intensity, and also reduces the possibility of cross-contamination between samples, making the sample processing process consistent and controllable.

[0004] The negative pressure cavity mentioned above needs to be emptied in a timely manner after the experimental waste liquid is collected, in order to prepare for the next experiment. This increases the complexity of the experimental process and reduces the efficiency of the experiment. Utility Model Content

[0005] To address the shortcomings of the existing technology, the purpose of this invention is to provide a waste liquid temporary storage device. On the one hand, the temporary storage tank can increase the accumulation of waste liquid capacity, and on the other hand, the diaphragm pump can remove the waste liquid without dismantling the temporary storage tank, further reducing the operation steps in the experimental process and effectively improving experimental efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a waste liquid temporary storage device, including a temporary storage tank with a cavity, a vacuum pump located on one side of the temporary storage tank, and a diaphragm pump located on one side of the temporary storage tank. The vacuum pump is connected to the top of the temporary storage tank and forms a negative pressure environment inside the temporary storage tank. The diaphragm pump is connected to the bottom of the temporary storage tank, and the outlet of the diaphragm pump is connected to a waste liquid collection tank. The diaphragm pump controls the pumping of waste liquid from the temporary storage tank into the waste liquid collection tank.

[0007] Preferably, a visual level gauge is provided on one side of the temporary storage tank.

[0008] Preferably, the system also includes a control panel electrically connected to the visual level gauge. The control panel is electrically connected to the diaphragm pump, and the diaphragm pump is controlled to perform suction by setting a level threshold.

[0009] Preferably, the temporary storage box includes a bottom box and a top cover locked to the bottom box. The vacuum pump and the diaphragm pump are respectively installed on one side of the bottom box. A liquid inlet is provided on one side of the bottom box near the top cover. An electric valve is provided at the liquid inlet, and the waste liquid in the temporary storage box is allowed to flow in by controlling the electric valve.

[0010] Preferably, the temporary storage box is covered with a protective frame, and the protective frame has a compartment on one side of the temporary storage box, in which the diaphragm pump and the vacuum pump are both installed.

[0011] Preferably, the protective frame has honeycomb holes at the compartment to allow ventilation for the compartment.

[0012] Preferably, a digital pressure gauge for detecting the air pressure inside the temporary storage box is provided on one side of the temporary storage box.

[0013] In summary, the beneficial effects of this invention are as follows: a vacuum pump creates a negative pressure environment in a storage tank with an open cavity. This continuous negative pressure environment draws externally connected waste liquid into the storage tank for temporary storage. The waste liquid stored in the storage tank is then extracted by a diaphragm pump and flows through the outlet of the diaphragm pump into a waste liquid collection bucket. On the one hand, the storage tank increases the accumulation of waste liquid capacity; on the other hand, the diaphragm pump's extraction of waste liquid avoids the need to dismantle the storage tank, further reducing the operational steps in the experimental process and effectively improving experimental efficiency.

[0020] A waste liquid temporary storage device, see Figures 1-3 The system includes a temporary storage tank 1 with a cavity, a vacuum pump 11 located on one side of the temporary storage tank 1, and a diaphragm pump 12 located on one side of the temporary storage tank 1. The vacuum pump 11 is connected to the top of the temporary storage tank 1 and creates a negative pressure environment inside the temporary storage tank 1. The diaphragm pump 12 is connected to the bottom of the temporary storage tank 1, and the outlet of the diaphragm pump 12 is connected to a waste liquid collection tank 13. The diaphragm pump 12 controls the pumping of waste liquid from the temporary storage tank 1 into the collection tank.

[0021] In this embodiment, a vacuum pump 11 creates a negative pressure environment in a temporary storage tank 1 with an open cavity. The externally connected waste liquid is drawn into the temporary storage tank 1 for temporary storage under the continuous negative pressure environment. The waste liquid temporarily stored in the temporary storage tank 1 is then extracted by a diaphragm pump 12 and flows through the outlet of the diaphragm pump 12 to the waste liquid collection tank 13. On the one hand, the temporary storage tank 1 can increase the accumulation of waste liquid capacity. On the other hand, the extraction of waste liquid by the diaphragm pump 12 can avoid the removal of the temporary storage tank 1, further reducing the operation steps in the experimental process and effectively improving the experimental efficiency.

[0022] Specifically, a visual level gauge 14 is installed on one side of the temporary storage tank 1. The volume of waste liquid in the temporary storage tank 1 can be observed through the visual level gauge 14.

[0023] Specifically, it also includes a control panel electrically connected to the visual level gauge 14. The control panel is electrically connected to the diaphragm pump 12. By setting a level threshold, the control panel controls the diaphragm pump 12 to perform suction.

[0024] To prevent excessive liquid level in the temporary storage tank 1, the change in waste liquid can be observed at any time through the visual level gauge 14. At the same time, it can be controlled through the control panel. When the liquid level in the temporary storage tank 1 reaches the liquid level threshold, the diaphragm pump 12 is controlled through the control panel to pump out the liquid to prevent the liquid level in the temporary storage tank 1 from being too high.

[0025] Specifically, the temporary storage box 1 includes a bottom box 16 and a top cover 15 locked onto the bottom box 16. The vacuum pump 11 and the diaphragm pump 12 are respectively installed on one side of the bottom box 16. A liquid inlet 17 is provided on one side of the bottom box 16 near the top cover 15. The liquid inlet 17 is equipped with an electric valve, and the waste liquid in the temporary storage box 1 is allowed to flow in by controlling the electric valve.

[0026] Since the temporary storage box 1 needs to create a negative pressure environment inside the box, an electric valve is installed through the liquid inlet 17. The electric valve is used to open and close the liquid inlet 17. When the electric valve is opened, the external waste liquid is drawn into the temporary storage box 1 through the negative pressure of the temporary storage box 1 for temporary storage.

[0027] Specifically, the temporary storage tank 1 is covered by a protective frame 2, and the protective frame 2 has a compartment 21 on one side of the temporary storage tank 1. The diaphragm pump 12, the visual level gauge 14, and the vacuum pump 11 are all installed in the compartment 21. By using the compartment 21, the external vacuum pump 11, diaphragm pump 12, and visual level gauge 14 are arranged in a unified manner, which facilitates subsequent maintenance.

[0028] Specifically, the protective frame 2 has honeycomb holes 22 at the compartment 21, through which the compartment 21 is ventilated. The vacuum pump 11 and diaphragm pump 12 generate heat during use, and the ventilation effect of the honeycomb holes 22 can effectively reduce the temperature inside the compartment 21, which is beneficial to the operation of the vacuum pump 11 and diaphragm pump 12.

[0029] Specifically, a digital pressure gauge 23 for detecting the air pressure inside the temporary storage box 1 is installed on one side. The pressure value inside the temporary storage box 1 can be observed in real time through the digital pressure gauge 23, and the vacuum pump 11 is controlled to perform vacuuming by setting the pressure required to create a negative pressure environment inside the temporary storage box 1 through the control panel.

[0030] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
