A waste liquid collection device for environmental monitoring

Abstract

This utility model relates to a waste liquid collection device for environmental testing, installed on one side of a testing platform, including a horizontal rail, adsorption guns, and a pump body. The operator places multiple test tubes containing waste liquid to be treated on the testing platform. The pump body starts working, generating negative pressure suction. This suction is transmitted to each adsorption gun through a pipe assembly, a series-connected three-way valve horizontal pipe network, and via an insertion tube and a first flexible tube. Under negative pressure, the waste liquid in the test tubes is sequentially drawn into a closed collection pipeline composed of the three-way valve and the pipe assembly through a drainage tube, a solenoid valve, the first flexible tube, and the insertion tube. All the drawn-out waste liquid collects within the closed pipe network and is finally drawn into the pump body through its inlet, and then safely transported from its outlet through a second flexible tube to a designated collection bucket for centralized storage. After the extraction operation is completed, the solenoid valve and the pump body can be closed.

Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a device for collecting waste liquid in environmental monitoring. Background Technology

[0002] In routine experiments in the field of environmental monitoring, a large amount of testing waste liquid containing various chemical reagents, biological samples, and unknown pollutants is generated. This waste liquid has a complex composition and significant potential hazards; its standardized and safe collection and disposal is a crucial part of laboratory operations, directly affecting the health and safety of laboratory personnel, the cleanliness of the laboratory environment, and the effectiveness of subsequent harmless treatment. Currently, the methods for collecting this type of waste liquid in laboratories remain relatively traditional and inefficient. The most common method is manual dumping, as seen in patent publication number CN221395310U - Chinese Utility Model Patent for an Environmental Testing Waste Liquid Collection Device. Essentially, this method still requires operators to manually pick up the container containing the waste liquid and pour it into a centralized collection bucket. While this method is structurally simple, the possibility of liquid splashing and leakage during the dumping process poses safety hazards and secondary pollution. Utility Model Content

[0003] The main purpose of this invention is to provide a waste liquid collection device for environmental testing, so as to solve the problem that existing environmental testing waste liquid collection devices may cause liquid splashing and leakage during the pouring process, which may lead to safety hazards and secondary pollution.

[0004] To achieve the above objectives, this utility model provides a waste liquid collection device for environmental testing, which is installed on one side of the testing platform and includes a horizontal rail, an adsorption gun, and a pump body. A horizontally set cross rail is fixed to one side of the testing table, and multiple sliders are slidably mounted thereon. Each slider is fixed with a bracket, the bottom of the bracket is detachable with a three-way connector, the vertical tube of the three-way connector is detachable with a sealing cap, and the sealing cap is used to fix multiple insertion tubes. The number of suction guns and insertion tubes are the same, and there is a one-to-one correspondence between them; Each adsorption gun can be hung on the top of the bracket and includes a solenoid valve and a drain pipe. The inlet of the solenoid valve is connected to the drain pipe, and the outlet is connected to the insertion tube through a first flexible tube. The pump body's inlet is connected in series with the horizontal pipes at both ends of multiple three-way valves via a pipe assembly, and the outlet is connected to a collection tank via a second flexible pipe.

[0005] A preferred embodiment is that the top of the support has a horizontal plate located directly above the testing table, and a strip-shaped groove is formed along its length, allowing the solenoid valve to rest on the horizontal plate so that the drainage tube can be inserted into the strip-shaped groove.

[0006] A preferred approach is to have multiple drainage tubes of different diameters located on the same support.

[0007] A preferred embodiment is that the vertical tube of the three-way connector has an external thread on its circumference, the sealing cap has an internal thread on its circumference, the external thread and the internal thread are screwed together, the top end of the insertion tube is connected to the first flexible tube, and the bottom end is connected to the three-way connector.

[0008] A preferred embodiment is that the piping assembly includes a plug, an installation pipe, and multiple receiving pipes; The end of the sealing pipe furthest from the sealing opening is connected to the horizontal pipe of the tee located at the beginning, and the two ends of each receiving pipe are connected to the horizontal pipes of the adjacent tee respectively; The two ends of the installation pipe are connected to the horizontal pipe of the tee located at the tail end and the pump body, respectively.

[0009] A preferred option is to use a telescopic pipe or a flexible hose as the receiving pipe.

[0010] A preferred embodiment is that the number of the second flexible tube and the collection bucket are multiple sets, and the two correspond one-to-one.

[0011] A preferred solution is that sealing blocks can be detachably installed at both ends of the horizontal rail.

[0012] The beneficial effects of the above scheme are: The slider is moved along the horizontally set rail to adjust the position of each support and its adsorption gun. The operator places multiple test tubes containing waste liquid to be treated on the testing platform. Each adsorption gun is removed from its support, and the drainage tube is inserted below the liquid level of the corresponding test tube. After completion, the adsorption gun can be hung back on the support for standby; this design facilitates positioning and management. The pump is turned on and the solenoid valves on each adsorption gun are controlled. The pump starts working and generates negative pressure suction. This suction is transmitted to each adsorption gun through the pipe assembly, the series-connected three-way horizontal pipe network, and through the insertion tube and the first flexible tube. Under the action of negative pressure, the waste liquid in the test tube is sequentially drawn into the closed collection pipeline composed of the three-way valve and the pipe assembly through the drainage tube, the solenoid valve (in the open state), the first flexible tube, and the insertion tube. All the drawn-out waste liquid is collected in the closed pipe network and finally sucked in through the pump inlet and safely transported from its outlet through the second flexible tube to the designated collection bucket for centralized storage. After the extraction operation is completed, the solenoid valve and the pump can be turned off. This structure achieves the following effect: I. By setting up multiple independently controllable adsorption guns and parallel collection pipelines, the synchronous and automated extraction and collection of multiple sample waste liquids is realized, which greatly improves the waste liquid collection efficiency and significantly reduces the labor intensity and time cost of operators.

[0013] Second, the entire waste liquid transfer process is completed in a closed pipeline system, which fundamentally eliminates the problems of splashing, dripping, and evaporation that may occur during the waste liquid dumping process, effectively protects the health and safety of laboratory personnel, prevents secondary pollution of the laboratory environment by harmful substances, and complies with safe and environmentally friendly operating procedures.

[0014] Third, the adsorption gun can be hung on the bracket for easy access and positioning. The bracket is connected to the horizontal rail via a slider, and the front and rear layout can be flexibly adjusted according to the position of the test tubes on the experimental table, making the operation process smoother and more user-friendly.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0019] like Figures 1-4As shown, this embodiment provides a waste liquid collection device for environmental testing, installed on one side of a testing platform 1, including a horizontal rail 10, an adsorption gun 50, and a pump body 60. The horizontally arranged horizontal rail 10 is fixed to one side of the testing platform 1, and multiple sliders 11 slide along the horizontal rail 10. Both ends of the horizontal rail 10 are detachably equipped with sealing blocks 90. The sealing blocks 90 prevent the sliders 11 from sliding off the horizontal rail 10. Each slider 11 is fixed with a bracket 20, and the bottom end of the bracket 20 has a detachable three-way connector 30 (i.e., a right-angle three-way connector). The vertical tube of the three-way connector 30 has a detachable sealing cap 40, and multiple insertion tubes 41 are fixedly inserted into the sealing cap 40. The number of adsorption guns 50 and insertion tubes 41 are the same, and they correspond one-to-one. Each adsorption gun 50 can be hung on the top of the bracket 20, and each adsorption gun 50 includes a solenoid valve 51 and a drainage pipe 52. The inlet of the solenoid valve 51 is connected to the drainage pipe 52, and the outlet of the solenoid valve 51 is connected to the insertion pipe 41 through a first flexible pipe (not shown). The top of the bracket 20 has a horizontal plate 21, which is located directly above the detection platform 1. The horizontal plate 21 has a strip-shaped through groove 210 along its length. The solenoid valve 51 can be placed on the horizontal plate 21, so that the drainage pipe 52 is inserted into the strip-shaped through groove 210. The solenoid valve 51 can be a HACH NPW-150 or SMC VQZ100 series model, etc. The inlet of the pump body 60 is connected in series with the horizontal pipes at both ends of multiple three-way valves 30 through the pipe group 70, and the outlet of the pump body 60 is connected to the collection tank 81 through the second flexible pipe 80. There are multiple sets of the second flexible pipe 80 and the collection tank 81, and they correspond one-to-one. Among them, the pump body 60 can be selected from Langheng BT100-1J + DG series pump heads or KNF NF 1.5 series models, etc.

[0020] The slider 11 is moved along the horizontally set cross rail 10 to adjust the position of each support 20 and its adsorption gun 50. The operator places multiple test tubes containing waste liquid to be treated on the testing table 1. Each adsorption gun 50 is removed from its support 20, and the drainage tube 52 is inserted below the liquid surface of the corresponding test tube. After completion, the adsorption gun 50 can be hung back on the support 20 for standby, a design that facilitates positioning and management. The pump body 60 is turned on and the solenoid valve 51 on each adsorption gun 50 is controlled. The pump body 60 starts to work and generates negative pressure suction. This suction is transmitted to each adsorption gun 50 through the pipe group 70, the series-connected three-way valve 30 horizontal pipe network, and through the insertion tube 41 and the first flexible tube. Under the action of negative pressure, the waste liquid in the test tube is sequentially drawn into the closed collection pipeline composed of the three-way valve 30 and the pipe group 70 through the drainage tube 52, the solenoid valve 51 (in the open state), the first flexible tube, and the insertion tube 41. All extracted waste liquid is collected within a closed pipeline network and ultimately drawn into the pump body 60 through its inlet. From the outlet, it is safely transported through the second flexible pipe 80 to a designated collection tank 81 for centralized storage. After the extraction operation is completed, the solenoid valve 51 and pump body 60 can be closed. This structure achieves the following effects: 1. By setting up multiple independently controllable adsorption guns 50 and parallel collection pipelines, simultaneous and automated extraction and collection of multiple sample waste liquids are achieved, greatly improving waste liquid collection efficiency and significantly reducing the labor intensity and time costs for operators. 2. The entire waste liquid transfer process is completed within a closed pipeline system, fundamentally eliminating potential splashing, dripping, and evaporation problems during waste liquid disposal. This effectively protects the health and safety of laboratory personnel, prevents secondary pollution of the laboratory environment by harmful substances, and complies with safe and environmentally friendly operating procedures. Third, the adsorption gun 50 can be hung on the bracket 20 for easy access and positioning. The bracket 20 is connected to the horizontal rail 10 via the slider 11, and the front and rear layout can be flexibly adjusted according to the position of the test tubes on the experimental table, making the operation process smoother and more user-friendly.

[0021] Multiple drainage tubes 52 located on the same support 20 have different diameters. The vertical tube of the three-way connector 30 has an external thread 301 on its circumference, and the sealing cap 40 has an internal thread (not shown) on its circumference. The external thread 301 and the internal thread are screwed together. The top end of the insertion tube 41 communicates with the first flexible tube, and the bottom end of the insertion tube 41 communicates with the three-way connector 30. Through the threaded connection, disassembly and assembly can be completed quickly. The pipe assembly 70 includes a sealing tube 71 with one closed end, an installation tube 72, and multiple receiving tubes 73. The end of the sealing tube 71 away from the sealing end communicates with the horizontal tube of the three-way connector 30 at the beginning. The two ends of each receiving tube 73 communicate with the horizontal tubes of adjacent three-way connectors 30. The two ends of the installation tube 72 communicate with the horizontal tube of the three-way connector 30 at the end and the pump body 60, respectively. The receiving tubes 73 are telescopic tubes or flexible hoses. The receiving tubes 73 are telescopic or flexible hoses (such as PTFE hoses), allowing the pipe assembly 70 to adapt to the dynamic layout changes of the test tube rack on the testing table 1. When the slider 11 is adjusted along the horizontal rail 10, the flexible bearing pipe 73 can compensate for the positional deviation by bending or stretching, thus avoiding stress concentration or loosening of the interface caused by rigid pipe connection.

[0022] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
