Description

Technical Field

[0001] The invention relates to the field of experimental equipment, and in particular to a device for rough treatment and recovery of experimental waste liquid. Background Art

[0002] Currently, laboratory experiments generate large amounts of wastewater. Advanced laboratories utilize specialized treatment systems to handle this wastewater. In ordinary laboratories, however, this wastewater is typically dumped into the sewer without undergoing any extensive treatment. This is due to the high cost of installing a comprehensive wastewater treatment system and the need for dedicated personnel to maintain it, rendering the entire system useless. Therefore, to address these issues, a device for the rough treatment and recovery of wastewater generated during laboratory experiments is proposed. Summary of the Invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a device for rough treatment and recovery of experimental waste liquid.

[0004] According to the technical solution provided in the embodiments of the present application, a device for rough treatment and recovery of experimental waste liquid includes a housing. The housing is mainly made of stainless steel or a corrosion-resistant polymer material, and can be made into different shapes according to user and environmental needs. Level beads are embedded on several upper side edges of the top surface of the housing to determine whether the device is in a horizontal state after installation. Correspondingly, a fine-tuning pad is installed at the bottom of the device, which can be adjusted in height by rotation to adapt to a horizontal plane with a small error.

[0005] The shell consists of an upper part and a lower part.

[0006] The upper portion includes a liquid inlet hopper. Several circular holes are provided on the upper surface of the shell, with the liquid inlet hoppers mounted on these holes using industrial glue. The height of the liquid inlet hopper is slightly higher than the top surface of the shell. A 4-7 cm wide trapezoidal groove is defined at the point of contact between the liquid inlet hopper and the shell top surface. The trapezoidal groove is divided into two steps. The diameter of the first step groove is 2 cm larger than the diameter of the liquid inlet hopper, while the diameter of the second step groove is larger than the diameter of the first step groove. An alkaline adsorption layer is laid within the first step groove. A sealing rubber ring is installed at the connection between the liquid inlet hopper and the shell, and alkaline glue is also used to seal the connection to prevent leakage.

[0007] The best thing is to place particles that generate smoke when exposed to water on the lowest layer of the first-level groove. If waste liquid leaks into the groove, smoke may be generated, indicating that there is a leakage and it needs to be cleaned in time.

[0008] The filter mechanism is secured to the outlet below the liquid inlet hopper via an iron hoop. It consists of a fixed bracket and a filter seat, with matching clips between the bracket and the filter seat. The filter seat is equipped with a concave ceramic filter screen. The ceramic filter screen has a trapezoidal structure, with the outer edge of each layer 1mm-3mm higher than the inner edge. The ceramic filter screen has two hollow layers with soft magnetic strips installed inside. A single layer of filter paper is placed between the two layers of ceramic filter screen. To replace the filter paper, reverse the process: first remove the upper ceramic filter screen, then replace the filter paper.

[0009] A one-way valve is installed between the liquid inlet pipe and the filter mechanism to prevent the liquid in the liquid inlet pipe from overflowing when too much liquid is poured into the filter mechanism. At the same time, the one-way valve can be cancelled in principle.

[0010] The deactivation mechanism is connected to the L-shaped liquid inlet pipe below the filtering mechanism. The deactivation mechanism is wrapped around the upper end of the liquid inlet pipe, and the magnetization mechanism is wrapped around the lower end of the liquid inlet pipe. The magnetization mechanism mainly includes an electromagnetic induction coil. When energized, it generates a magnetic field that can magnetize the liquid, magnetizing and passivating the active substances and water in the liquid. A magnetic barrier layer made of magnetic barrier material is placed around the electromagnetic induction coil to prevent the generated magnetic field from causing functional damage to other electronic components.

[0011] The deactivation mechanism includes an eddy current heater, a mounting bracket, a current controller, and a thermal insulation layer. The mounting bracket is installed at the bottom of the upper part by screws. The eddy current heater and the liquid inlet pipe are both fixed on the mounting bracket. The eddy current heater is sleeved on the liquid inlet pipe. The current controller is connected to the circuit board of the eddy current heater, and the thermal insulation layer is wrapped around the outside of the eddy current heater.

[0012] The lower part includes a multi-way valve body, a liquid storage tank, a push-pull mechanism, a lifting, alignment and locking mechanism, and an acidification mechanism. Several push-pull mechanisms are installed at the bottom of the shell of the lower part. The lifting, alignment and locking mechanism is installed on the push-pull mechanism. The liquid storage tank is placed on the lifting, alignment and locking mechanism. The acidification mechanism is installed on the side of the shell of the lower part. The outlet of the mechanism is connected to the multi-way valve body through a solenoid valve. The multi-way valve body is also connected to the liquid inlet pipe. Each outlet of the multi-way valve body corresponds to a liquid storage tank.

[0013] The lifting alignment locking mechanism includes a positioning column, a pressure sensor installed on the bottom surface of the upper part and a lifting platform, and the positioning column is installed on a corner of the lifting platform.

[0014] The push-pull mechanism includes a slide rail and a slidable locking member. The slidable locking member is arranged on the slide rail to achieve reciprocating sliding. The slidable locking member is provided with a screw that is tightened to achieve locking. The tightness is appropriate and does not require excessive tightening. Whether locking or loosening, it can be manually operated.

[0015] A protective door is also provided on the side of the shell, and a handle is provided on the protective door.

[0016] The acidification mechanism includes a glass box, a liquid inlet pipe and a manual valve body. The glass box is fixed inside the lower part through a bracket, the upper end is connected to the liquid inlet pipe, and the side end is connected to the liquid outlet pipe. The liquid outlet pipe is connected to the multi-way valve body through the manual valve body.

[0017] In summary, the beneficial effects of this application are:

[0018] 1. Use centralized treatment of experimental wastewater to prevent wastewater from being poured into the sewer after the experiment, causing pollution to urban water bodies and preventing harmful bacteria from entering the water bodies;

[0019] Second, the deactivation mechanism made of eddy current heater can quickly heat the waste liquid, so that the waste liquid is fully heated and the active substances in the waste liquid are disinfected at high temperature;

[0020] 3. Use an acidification mechanism and add sulfuric acid or hydrochloric acid to inactivate the remaining active substances. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] like Figure 1 - Figure 5 As shown, a device for rough treatment and recovery of experimental waste liquid includes a housing 200. Housing 200 is primarily made of stainless steel or a corrosion-resistant polymer material and can be formed into various shapes according to user and environmental needs. It occupies an area of ​​approximately 1 to 2 square meters. Housing 200 consists of an upper portion and a lower portion. If the volume of this product is large enough, the upper portion's liquid inlet hopper 1 can adopt a sealed structure, that is, connected to the outlet pipe of a pool on the laboratory table via a water pipe as needed. Then, when the experimenter pours the waste liquid, they can pour it directly into the pool. This solution can also be expanded into multiple combined structures as needed.

[0039] When installing this product, the floor must be leveled, ideally with an error of no more than 5mm. If the floor is unsuitable, fine-tuning pads 201 can be installed on the product's feet. By applying pressure to the fine-tuning pads 201, the height can be adjusted to a consistent level. Leveling beads are embedded on several upper edges of the top surface of the housing 200 to determine whether the device is level after installation.

[0040] When in use, it is necessary to connect the power cord to the mains to preheat and run a safety check through the self-test software. If there are no problems, the alarm light will turn green. If there are problems with the current controller 52 or other electronic components, a red light will turn on and a voice alarm will sound.

[0041] The trapezoidal groove of the liquid inlet hopper 1 contains particles that generate mist when exposed to water. If a user accidentally pours liquid into the trapezoidal groove, a smoke warning will be immediately emitted. These smoke-generating particles primarily react with water to produce water vapor. Quicklime is a preferred choice, as the heat generated can eliminate active substances in the leaked liquid. Since it is located in the concave layer, it will not cause burns to personnel. Of course, this process releases heat and carries a certain degree of risk. Therefore, it is best to lay an alkaline adsorption layer in the first-stage groove. While the alkaline adsorption layer absorbs the leaked liquid, it also destroys other biochemical components in the liquid, minimizing the risk of leakage. Furthermore, a sealing rubber ring is installed at the connection between the liquid inlet hopper 1 and the housing 200, and alkaline glue is also used for sealing to prevent leakage. The trapezoidal groove is divided into two steps. The diameter of the first step groove is 2 cm larger than the diameter of the liquid inlet hopper 1, and the diameter of the second step groove is larger than the first step groove. This double-layer design effectively prevents leaked liquid from dripping onto the outside. Leakage requires prompt cleaning.

[0042] After the liquid enters the filter mechanism 2 through the inlet hopper 1, it enters the ceramic filter screen 22. This two-layered ceramic filter screen 22 is hollow and contains soft magnetic strips that attract each other. A single layer of filter paper 23 is placed between the two layers of ceramic filter screen 22. The double-layered ceramic filter screen 22 effectively holds the single layer of filter paper 23, which also requires cremation upon recycling. After the liquid passes through the ceramic filter screen 22 and the single layer of filter paper 23, large particles in the liquid are filtered out, preventing them from entering the pipeline with the liquid and potentially accumulating over time, which could affect the service life of the entire device. The ceramic filter screen 22 has a trapezoidal structure, with the outer edge of each layer 1mm-3mm higher than the inner edge. This design prevents liquid from overflowing during filtration. When there are too many large particles in the ceramic filter screen 22 or the filter paper needs to be replaced, the filter paper does not need to be replaced every time, even if it is a disposable item. If a plastic filter material with micropores is used for better effect, since there are corresponding buckles between the fixing bracket 20 and the filter seat 21, you only need to remove the filter seat 21 to take out the ceramic filter screen 22 and the single-layer filter paper 23 for replacement and cleaning.

[0043] The filter mechanism 2 is connected to the multi-way valve body 6 through different liquid inlet pipes 3. A one-way valve is also installed between the liquid inlet pipe 3 and the filter mechanism 2 to prevent the liquid in the liquid inlet pipe from overflowing when too much liquid is poured into the filter mechanism 2. At the same time, the one-way valve can be cancelled in principle.

[0044] The deactivation mechanism 5 is connected to the L-shaped liquid inlet pipe 3 below the filtering mechanism 2. The deactivation mechanism 5 is wrapped around the upper end of the liquid inlet pipe 3, and the magnetization mechanism 4 is wrapped around the lower end of the liquid inlet pipe 3. The magnetization mechanism 4 mainly includes an electromagnetic induction coil. When energized, it generates a magnetic field that can magnetize the liquid, magnetizing and passivating the active substances and water in the liquid. The electromagnetic induction coil is coated with a magnetic-resistance layer made of a magnetic-resistance material to prevent the generated magnetic field from causing functional damage to other electronic components.

[0045] The deactivation mechanism 5 includes an eddy current heater 50, a mounting bracket 51, a current controller 52, and an insulation layer 53. The mounting bracket 51 is installed at the bottom of the upper part by screws. The eddy current heater 50 and the liquid inlet pipe 3 are both fixed on the mounting bracket 51. The eddy current heater 50 is sleeved on the liquid inlet pipe 3. The current controller 52 is connected to the circuit board of the eddy current heater 50, and the insulation layer 53 is wrapped around the outside of the eddy current heater 50.

[0046] The lower part includes a multi-way valve body 6, a liquid storage tank 7, a push-pull mechanism 8, a lifting alignment locking mechanism 9, and an acidification mechanism 10. Several push-pull mechanisms 8 are installed at the bottom of the shell of the lower part. The lifting alignment locking mechanism 9 is installed on the push-pull mechanism 8. The liquid storage tank 7 is placed on the lifting alignment locking mechanism 9. The acidification mechanism 10 is installed on the side of the shell of the lower part, and its outlet is connected to the multi-way valve body 6 through a solenoid valve. The multi-way valve body 6 is also connected to the liquid inlet pipe 3. Each outlet of the multi-way valve body 6 corresponds to a liquid storage tank 7.

[0047] The push-pull mechanism 8 includes a slide rail 80 , a slidable locking member 81 , a protective door 82 and a handle 83 .

[0048] The acidification mechanism 10 includes a glass box 100, a liquid inlet pipe 101 and a manual valve body 102. The glass box 100 is fixed inside the lower part by a bracket. The upper end is connected to the liquid inlet pipe 101 (the liquid inlet pipe 101 is optional, but in order to prevent misoperation and accidents caused by sulfuric acid dripping into water causing the water surface to boil, the liquid inlet pipe 101 should be added when appropriate. Normal operation is: first add a large amount of water to the glass box 100, and then add an appropriate amount of sulfuric acid to acidify the water. Do not add sulfuric acid first and then water.) and the side end is connected to the liquid outlet pipe 103, which is connected to the multi-way valve body 6 through the manual valve body 102.

[0049] The center points of the pressure sensor 91 mounted on the bottom surface of the upper portion and the positioning column 90 mounted on a corner of the lifting platform 92 are located on the same horizontal line. When the lifting platform 92 rises, the positioning column 90 hits the pressure sensor 91, and the corresponding indicator light will light up green. Under normal circumstances, alignment can be achieved as long as the push-pull mechanism 8 is pushed to the top. However, to prevent misalignment due to human factors, the positioning column 90 and the pressure sensor 91 are provided to prevent misalignment. If misalignment occurs, an alarm will be illuminated, and the solenoid valve will be locked, prohibiting liquid discharge. The positioning column 90 is slightly higher than the liquid storage tank 7 and can be set according to the installation situation of the pressure sensor 91, as long as accurate positioning is achieved.

[0050] The lifting platform 92 on the lifting alignment locking mechanism 9 has a clamping seat on both sides for clamping the liquid storage tank 7 and positioning the liquid storage tank 7. The liquid storage tank 7 is also provided with a groove adapted to the clamping seat. The lifting platform 92 is an existing small lifting mechanism that can be manually lifted or electrically lifted. In this solution, the electrically lifted one is generally realized by a micro hydraulic cylinder. The manual one is generally realized by the principle of a jack.

[0051] like Figure 6As shown, water is added via a water injector through the liquid inlet pipe 101. The water enters the glass box 100, and then sulfuric acid, hydrochloric acid, or nitric acid is added dropwise until the pH reaches 2.5-3.5. Since the glass box 100 varies in size, the volume of water added should also vary according to the requirements. Generally speaking, the water should be added to 70%-80% of the glass box 100. The required volume of sulfuric acid is calculated based on the volume of water added and the desired acidity. The water in the glass box 100 is acidified and set aside. When necessary, manually open the manual valve body 102, and the acidified water flows out through the liquid outlet pipe 103 into the multi-way valve body 6, and then enters the liquid storage tank 7 to acidify the water therein. According to the volume ratio of the water in the glass box 100 and the water in the liquid storage tank 7, the acidity of the water in the liquid storage tank 7 will eventually be around pH 4-pH 5. If it fails to meet the standard, it is necessary to prepare acidified water again and add it multiple times, or directly drip sulfuric acid into the liquid storage tank 7 in the future.

[0052] The fine-tuning pad 201 is adjusted in a threaded manner, that is, it includes a pad and a threaded tube. The threaded tube is welded to the bottom of the shell 200, and the pad is provided with a screw hole adapted to the fine-threaded tube. When adjusting, fine-tuning can be achieved by rotating the pad.

[0053] In this scheme, the mains electricity is used for operation, and the circuit diagram is as follows Figure 6 As shown, when AC power enters the device, it is stepped down to 12V and 36V by the voltage conversion circuit board. The 12V is supplied to small electrical components, such as the pressure sensor 91 and the solenoid valve bodies. In existing products, each small electrical component has its own step-down circuit for stepping down the 12V. The 36V is supplied to the magnetizing mechanism 4, the deactivation mechanism 5, and the eddy current heater 50. All three require a voltage boost, which is achieved through their respective boost circuits to meet operational requirements.

[0054] All electrical components used in this solution are existing products and have not been modified or improved. The components are connected by wires that must be able to withstand a current of 5A-10A. When not in use, the power supply must be disconnected to prevent damage to the equipment from prolonged operation.

[0055] The entire working process of the electrical signal of this scheme is as follows:

[0056] This device is equipped with a host computer (with an i32 processor, 4GB of memory, a GT430 graphics card, and Windows XP operating system; the screen is mounted on the housing 200 (not shown). A detection software provided by a certain company is installed within the system. After the host computer is powered on, a pressure sensor 91 (model AQDT-046, available online) first senses whether the liquid reservoir 7 is in the correct position. The pressure sensor 91 transmits a signal to the host computer, where the detection software then verifies the signal. If not, a red light illuminates, and a signal is sent through the host computer to lock all solenoid valves. If necessary, a speaker can be installed to provide an alarm. If correct, a green light illuminates, indicating that all solenoid valves are operational. Weight sensors (model DYLY-106) are installed within the glass box 100 and in the lift alignment locking mechanism 9. The host computer is also connected to the various solenoid valves to monitor and control them and the sensors. The current controller 52 (model SOC-AH6-2) and the chip circuitry within the eddy current heater 50 are also connected to the host computer.

[0057] This protocol is applicable to fungal, microbial, and living cell experiments, but not to viral experiments.
