Abstract
Description
Technical Field
[0001] This utility model specifically relates to a biological waste liquid treatment device. Background Technology
[0002] Surface plasmon resonance (SPR) molecular interaction instruments continuously generate biological waste liquids during the analysis of biomolecular interactions, mainly including: running buffers (such as HBS-EP, PBS+Tween), regeneration solutions (such as Glycine-HCl, NaOH, NaCl, MgCl2), immobilization buffers (such as acetate buffer), coupling reagents (such as EDC, NHS), blocking solutions (such as ethanolamine), etc.
[0003] In existing SPR molecular interaction instruments, the biological waste treatment device is typically directly connected to the waste liquid pipeline and uses a direct-jet structure. During actual use, when the waste liquid is sprayed at high speed into the waste treatment device, the liquid easily atomizes inside, generating a large amount of foam. This foam accumulates continuously inside the device and easily overflows from the pressure relief port, preventing the waste liquid from being completely collected in the waste liquid collector. The overflowing biological waste liquid flows into the instrument's interior, corroding instrument components and potentially causing instrument malfunctions. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model proposes a biological wastewater treatment device.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: This utility model discloses a biological waste liquid treatment device, comprising: Waste liquid treatment container, which has a treatment chamber and a drain port at the bottom of the treatment chamber for connection to a waste liquid collector; Pressure relief device, installed on top of the waste liquid treatment container; The pressure relief pipe has one end connected to the pressure relief device and the other end extended to the outside of the device. The biological wastewater treatment device also includes: The first-stage reducer is connected to the waste liquid inlet pipeline and is used to reduce the speed of the waste liquid entering the waste liquid treatment container. An isolation seat is installed in the inner cavity of a waste liquid treatment container. The isolation seat includes: an isolation plate, a float seat fixedly connected to the isolation plate, and a float installed in the inner cavity of the float seat. The partition plate divides the treatment chamber of the waste liquid treatment container into an upper chamber and a lower chamber, and the partition plate is provided with a through hole as a float valve port, and the diameter of the float is larger than the diameter of the float valve port. The float is used to move up and down in the internal cavity of the float seat under the action of foam, so as to switch the opening and closing state of the float valve port and prevent foam from entering the upper cavity from the lower cavity.
[0006] This utility model discloses a biological waste liquid treatment device, which has the following beneficial effects: First, the primary reducer slows down the high-speed waste liquid to prevent the liquid from being atomized at high speed, thus reducing foam generation at the source.
[0007] Second, the isolation plate divides the treatment chamber into upper and lower chambers. When foam accumulates, the float automatically rises and seals the float valve port, preventing foam from entering the upper chamber, thereby protecting the pressure relief device at the top.
[0008] This invention reduces the flow rate of waste liquid through a single-stage reducer, and the float and float valve work together to automatically block foam overflow, fundamentally solving the problems of foam overflow and waste liquid corrosion of instruments.
[0009] Based on the above technical solution, the following improvements can be made: As a preferred embodiment, the float seat includes several cavity structures that are connected vertically in sequence; From top to bottom, the radial diameter of the upper cavity is larger than that of the lower cavity, and the float can only move up and down in the uppermost cavity.
[0010] The above-mentioned preferred scheme, with its multi-stage gradient cavity structure, ensures stable guidance and reliable sealing of the float, preventing jamming and malfunction.
[0011] As a preferred option, the bottom of the lowest cavity in the internal cavity of the float seat has a mesh structure.
[0012] By adopting the above-mentioned preferred scheme, the mesh structure can not only ensure that the waste liquid in the lower cavity can smoothly enter the bottom of the float seat and maintain the smooth transfer between the liquid surface and the foam, but also play a certain role in filtering large particulate impurities, preventing them from entering the float's active area and causing jamming, thus ensuring the long-term stable operation of the float.
[0013] As a preferred embodiment, the single-stage reducer includes: a reduction gearbox and multiple reduction plates disposed within the reduction gearbox, wherein the multiple reduction plates are arranged in an alternating manner to form a meandering reduction flow channel.
[0014] By adopting the above-mentioned preferred scheme, the multi-layer speed reducer forms a meandering flow channel, which buffers the waste liquid in multiple stages, significantly reducing the flow rate and the amount of foam generated.
[0015] As a preferred option, the outlet diameter of the first-stage reducer is larger than its inlet diameter.
[0016] Using the preferred scheme described above, the outlet diameter is larger than the inlet diameter, and the first deceleration is achieved by utilizing the principle of fluid diffusion.
[0017] As a preferred embodiment, the inner cavity of the waste liquid treatment container is further provided with several guide plates. The upper end of the guide plate is fixedly connected to the lower surface of the isolation plate, and its lower end hangs freely. The guide plate is used to guide the splashed waste liquid to the drain port.
[0018] By adopting the above-mentioned preferred solution, the guide plate blocks splashing waste liquid, improves collection efficiency, and avoids secondary splashing and foaming of liquid.
[0019] As a preferred embodiment, the lower end of the guide plate has a wedge-shaped structure extending toward the drain outlet of the waste liquid treatment container.
[0020] With the preferred design described above, the wedge-shaped structure gradually narrows, guiding the liquid to flow towards the drain outlet and preventing liquid from stagnating or splashing at the bottom. Simultaneously, the sharp angles of the wedge's edge can puncture or compress foam bubbles as the liquid flows through, providing a mechanical defoaming effect. This is particularly effective at destroying small amounts of existing foam, further reducing the risk of foam accumulation.
[0021] As a preferred embodiment, the distance from the bottom of the guide plate to the drain outlet of the waste liquid treatment container is less than the distance from the bottom of the float seat to the drain outlet of the waste liquid treatment container.
[0022] With the above-mentioned preferred solution, the bottom of the guide plate is closer to the drain port, so that the liquid guided by the guide plate can directly and quickly enter the drain port, avoiding the disturbance caused by the liquid flowing through the bottom of the float seat.
[0023] As a preferred embodiment, a secondary reducer is also included, wherein the inlet of the secondary reducer is connected to the outlet of the primary reducer, and is used to perform a second reduction on the waste liquid after the first reduction.
[0024] By adopting the above-mentioned preferred scheme, a secondary reducer is added to decelerate the waste liquid a second time, further eliminating residual kinetic energy and foam.
[0025] As a preferred embodiment, the secondary reducer is an annular groove formed on the inner wall of the waste liquid treatment container, and the annular groove is connected to the outlet of the primary reducer through a pipeline.
[0026] Using the preferred scheme described above, the secondary reducer adopts an inner wall annular groove structure, which utilizes centrifugal force and gravity to make the waste liquid flow down the wall in a laminar flow, thus achieving bubble-free transportation. Attached Figure Description

Detailed Implementation
[0036] The preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] Using ordinal numbers such as “first,” “second,” “third,” etc. to describe ordinary objects merely indicates different instances of similar objects and is not intended to imply that the objects being described must have a given order in time, space, sequence, or any other way.
[0039] Furthermore, the expression "includes" is an "open-ended" expression, which means only that there is a corresponding component or step, and should not be interpreted as excluding additional components or steps.
[0040] like Figure 1-4 As shown, this embodiment provides a biological waste liquid treatment device, including: a waste liquid treatment container 1, a pressure relief device 2, a pressure relief pipe 3, a speed reducer, and an isolation seat 5.
[0041] The waste liquid treatment container 1 has a treatment chamber 11. The bottom of the treatment chamber 11 is designed as an inverted trapezoidal structure, that is, wider at the top and narrower at the bottom, with a drain port 12 at the narrow opening. The drain port 12 is connected to an external waste liquid collector 9 through a guide pipe 6.
[0042] The top of the waste liquid treatment container 1 is equipped with a pressure relief device 2. The pressure relief device 2 has a cylindrical filter cotton inside. The upper end of the pressure relief device 2 is connected to a pressure relief pipe 3, and the other end of the pressure relief pipe 3 extends to the outside of the device.
[0043] The waste liquid input pipeline is connected to the inlet of the first-stage reducer 4, and the outlet of the first-stage reducer 4 extends into the middle of the treatment chamber 11 of the waste liquid treatment container 1 (below the isolation seat 5).
[0044] The isolation seat 5 includes a horizontally arranged isolation plate 51. The edge of the isolation plate 51 is sealed and fixed to the inner wall of the processing chamber 11, dividing the processing chamber 11 into an upper chamber and a lower chamber. A circular hole is opened in the center of the isolation plate 51 as a float valve port 511. A float seat 52 is fixedly connected to the lower part of the isolation plate 51. The float seat 52 is cylindrical with a cavity inside, in which a foam float 53 is placed. The diameter of the float 53 is larger than the diameter of the float valve port 511 on the isolation plate 51.
[0045] During operation, the waste liquid is first reduced in speed by the first-stage reducer 4 and then enters the lower cavity of the treatment chamber 11. Most of the waste liquid flows into the waste liquid collector through the drain port 12 at the bottom of the inverted trapezoid and the guide pipe 6.
[0046] If the waste liquid produces foam, when the foam rises to the vicinity of the isolation plate 51, the float 53 floats up under the buoyancy of the foam, blocking the float valve port 511 and preventing the foam from entering the upper cavity, thereby protecting the pressure relief device 2 at the top. After the foam is intercepted, it enters the waste liquid collector 9 through the guide pipe 6.
[0047] This utility model discloses a biological waste liquid treatment device, which has the following beneficial effects: First, the first-stage reducer slows down the high-speed waste liquid to prevent the liquid from being sprayed and atomized at high speed, thus reducing foam generation at the source.
[0048] Second, the isolation plate 51 divides the processing chamber 11 into upper and lower chambers. When foam accumulates, the float ball 53 automatically floats up and blocks the float ball valve port 511, preventing foam from entering the upper chamber, thereby protecting the pressure relief device 2 at the top.
[0049] This invention reduces the flow rate of waste liquid by using a first-stage reducer 4, and the float 53 and float valve 511 work together to automatically block foam overflow, fundamentally solving the problems of foam overflow and waste liquid corrosion of instruments.
[0050] In order to further optimize the implementation effect of this utility model, in some other embodiments, the remaining features are the same, except that the float seat 52 is provided with a first cavity 541 and a second cavity 542 that are connected vertically in sequence.
[0051] The radial diameter of the upper first cavity 541 is larger than the radial diameter of the lower second cavity 542, and the float 53 can only float up and down within the first cavity 541.
[0052] The first cavity 541 and the second cavity 542 are connected through a cross-shaped through hole 543, as shown above. Figure 5 As shown.
[0053] Furthermore, based on the above embodiments, the bottom of the second cavity 542 in the internal cavity of the float seat 52 is a mesh structure 544.
[0054] The mesh structure 544 can ensure that the waste liquid in the lower cavity can smoothly enter the bottom of the float seat 52, maintain the smooth transfer between the liquid surface and the foam, and also play a certain role in filtering large particulate impurities, preventing them from entering the float's active area and causing jamming, thus ensuring the long-term stable operation of the float.
[0055] To further optimize the implementation effect of this utility model, in some other embodiments, the remaining technical features are the same, the difference being that, for example... Figure 6-7As shown, the primary reducer 4 includes a reduction gearbox 41 and five layers of reduction plates 42 disposed within the reduction gearbox 41. The multiple reduction plates 42 are arranged in an alternating manner, that is, adjacent layers of reduction plates 42 extend from the left and right walls of the gearbox, respectively, and a gap is left between the free end of each layer of reduction plate 42 and the inner wall of the opposite side of the gearbox. After the waste liquid enters from the inlet, it passes through the first, second, ... fifth layers of reduction plates 42 in sequence, forming a meandering "S"-shaped deceleration channel 43. Each time it passes through a layer of reduction plates 42, the flow direction of the waste liquid changes once, the kinetic energy is dissipated step by step, the flow velocity is significantly reduced, and atomization and foam generation are effectively suppressed.
[0056] Furthermore, based on the above embodiments, the outlet diameter of the first-stage reducer 4 is larger than its inlet diameter, and the first deceleration is achieved by utilizing the fluid diffusion principle.
[0057] In order to further optimize the implementation effect of this utility model, in some other embodiments, the remaining features are the same, except that two guide plates 7 are provided in the inner cavity of the waste liquid treatment container 1. The upper end of the guide plate 7 is fixedly connected to the lower surface of the isolation plate 51, and its lower end hangs freely.
[0058] The guide plate 7 directs the splashed waste liquid to the drain port 12, blocking the splashed waste liquid, improving collection efficiency and preventing secondary splashing and foaming of the liquid.
[0059] Furthermore, based on the above embodiment, the lower end of the guide plate 7 has a wedge-shaped structure 71. Specifically, the thickness of the lower end of the guide plate 7 gradually decreases, forming an acute-angled edge, and the tip of the wedge points towards the drain port 12 at the bottom of the waste liquid treatment container 1.
[0060] As the liquid flows along the guide plate 7 to the bottom, the wedge-shaped tip guides the liquid to drip or flow to the vicinity of the drain port 12. At the same time, the sharp edge of the wedge can puncture the bubbles when it comes into contact with the foam, playing a mechanical defoaming role and further reducing the risk of foam accumulation.
[0061] Furthermore, based on the above embodiments, the distance from the bottom of the guide plate 7 to the drain port 12 of the waste liquid treatment container 1 is less than the distance from the bottom of the float seat 52 to the drain port 12 of the waste liquid treatment container 1.
[0062] Because the bottom of the guide plate 7 is closer to the drain port 12, the liquid guided by the guide plate 7 can directly and quickly enter the drain port 12 at the bottom of the inverted cone shape, avoiding the liquid flowing through the bottom of the float seat 52 and causing disturbance or impact, thus ensuring the stability of the liquid surface inside the float seat 52 and making the float more sensitive to foam.
[0063] To further optimize the implementation effect of this utility model, in some other embodiments, the remaining technical features are the same, except that a secondary reducer 8 is added inside the waste liquid treatment container 1. The inlet of the secondary reducer 8 is connected to the outlet of the primary reducer 4, and is used to reduce the waste liquid after the first reduction for the second time.
[0064] Furthermore, the secondary reducer 8 is an annular groove 81 formed on the inner wall of the waste liquid treatment container 1, and the annular groove 81 is connected to the outlet of the primary reducer 4 through a pipeline.
[0065] During operation, the waste liquid flows out from the first-stage reducer 4 and enters the annular tank 81 through the pipeline, where it undergoes circular motion. Centrifugal force pushes the waste liquid towards the bottom of the annular tank 81 (i.e., the inner wall of the container), while gravity causes the waste liquid to flow slowly downwards along the inner wall. Because the bottom of the container is an inverted trapezoid, the waste liquid flowing down the wall is guided towards the drain port 12. Finally, the waste liquid enters the waste liquid collector 9 through the drain port 12 and the guide pipe 6.
[0066] This structure avoids direct impact of liquid on the liquid surface, eliminating foam generated by the impact; at the same time, the annular groove 81 does not occupy the internal space of the container, has a compact structure, is easy to clean and maintain, and is very suitable for the treatment of corrosive waste liquid in SPR instruments.
