Description

Technical Field

[0001] This invention relates to the field of biological culture equipment technology, and in particular to a device for recycling condensate water from biological instruments. Background Technology

[0002] Biological culture devices are temperature-controllable systems with both cooling and heating capabilities. They are indispensable laboratory equipment for research and teaching departments in botany, biology, microbiology, genetics, virology, and environmental protection. They are widely used in constant temperature experiments, culture tests, environmental experiments, and play a crucial role in scientific research, environmental protection, and wastewater treatment.

[0003] When biological culture devices are used for cultivation, low-temperature culture or culture at specific humidity is sometimes required. Under low temperature or high humidity conditions, condensation will be generated inside the chamber. Traditional equipment directly discharges the condensation through the drain outlet, which requires regular emptying and is quite troublesome. At the same time, the condensation is prone to bacterial growth, which affects the laboratory environment and has certain drawbacks. Summary of the Invention

[0004] The purpose of this invention is to provide a device for recycling condensate water from biological instruments, which enables the recycling of condensate water after filtration and high-temperature sterilization, thereby improving water resource utilization.

[0005] To solve the above-mentioned technical problems, the present invention provides a biological instrument condensate recycling device, including an instrument body, the instrument body having a condensate drain outlet, the condensate drain outlet being connected to a filter, the outlet of the filter being connected to a heating vaporization device via a reflux pump, and the outlet of the heating vaporization device being connected to a circulating fan via a steam pipe for transporting vaporized condensate to the interior of the instrument body.

[0006] Furthermore, the filter includes a filter canister with a threaded sealing cap at the top opening. A filter mechanism is detachably mounted on the sealing cap via a connector. The filter mechanism includes a first mounting ring, an activated carbon box, and a second mounting ring arranged sequentially from top to bottom. A fiber filter screen is disposed inside the first mounting ring, activated carbon is filled in the activated carbon box, and a vacuum ultrafiltration membrane is disposed inside the second mounting ring. The outer walls of both the first and second mounting rings slide in contact with the inner wall of the filter canister. Several limiting plates are evenly spaced around the bottom surface of the first mounting ring. The inner wall of each limiting plate abuts against the outer wall of the activated carbon box. A connecting block is mounted on the bottom surface of each limiting plate, and a connecting groove matching the connecting block is formed on the top surface of the second mounting ring. The connecting block and the end face of the connecting groove are magnetically adsorbed together.

[0007] Furthermore, the activated carbon box includes a placement tube for holding the activated carbon. The opening end of the placement tube has an annular groove, and a matching mounting ring is inserted into the annular groove. A sealing plate for sealing the opening of the placement tube is fixedly connected to the mounting ring. Several water leakage holes are opened through the end face of the sealing plate and the inner end face of the placement tube.

[0008] Furthermore, a limiting ring for placing the second mounting ring is installed at the lower end of the inner side wall of the filter tank.

[0009] Furthermore, the connector includes several connecting frames that are slidably installed on the bottom surface of the sealing cover at uniform circumferential intervals. A movable insert is fixedly installed on the bottom surface of the connecting frame. A drive rod is hinged to the upper end of the side wall of the connecting frame. A drive disc is hinged to the end of the drive rod away from the connecting frame. The drive disc is mounted on the center of the bottom surface of the sealing cover via a drive shaft. The drive shaft passes through the sealing cover. A tension spring is connected between the drive disc and the bottom surface of the sealing cover. The tension spring is sleeved on the drive shaft.

This realizes the recycling of the condensate generated by the biological instrument after filtration, purification and sterilization, which improves the utilization rate of water resources, eliminates the need to regularly dump the condensate, reduces unnecessary trouble, and ensures a good experimental environment.

[0015] (2) The filter of the present invention adopts three layers of filtration: fiber screen, activated carbon and vacuum ultrafiltration membrane. The filtration effect is excellent.

[0023] The biological instrument condensate recycling device of the present invention will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the invention.

[0024] The invention is described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0025] like Figure 1-7 As shown in the figure, an embodiment of the present invention proposes a biological instrument condensate recycling device, including an instrument body 1. The instrument body 1 has a condensate drain outlet, which is connected to a filter 2. The outlet of the filter 2 is connected to a heating vaporization device 4 through a return pump 3. The outlet of the heating vaporization device 4 is connected to a circulating fan 5 through a steam pipe for transporting vaporized condensate to the inside of the instrument body 1.

[0026] The filter 2 can be used to filter and purify condensate. In one embodiment, the filter 2 includes a filter tank 6, with a sealing cap 7 threaded onto the top opening of the filter tank 6. A filter mechanism is detachably mounted on the sealing cap 7 via a connector. The filter mechanism includes a first mounting ring 8, an activated carbon box 9, and a second mounting ring 10 arranged sequentially from top to bottom. A fiber filter screen 11 is disposed inside the first mounting ring 8, activated carbon 12 is filled inside the activated carbon box 9, and a vacuum ultrafiltration membrane 13 is disposed inside the second mounting ring 10. The outer walls of both the first mounting ring 8 and the second mounting ring 10 are in sliding contact with the inner wall of the filter tank 6. A plurality of limiting plates 14 are evenly spaced around the bottom surface of the first mounting ring 8. The inner wall of the limiting plate 14 abuts against the outer wall of the activated carbon box 9. A connecting block 15 is mounted on the bottom surface of the limiting plate 14, and a connecting groove 16 matching the connecting block 15 is opened on the top surface of the second mounting ring 10. The connecting block 15 and the end face of the connecting groove 16 are magnetically adsorbed together. In this embodiment, the fiber filter 11 is used to remove larger particulate impurities, the activated carbon 12 is used to deodorize and decolorize the condensate, and the vacuum ultrafiltration membrane 13 is used to remove smaller impurities such as suspended solids and particles. The three-layer filtration provides excellent filtration results. The activated carbon box 9 is held by the first mounting ring 8 and the second mounting ring 10. The first mounting ring 8 and the second mounting ring 10 are magnetically connected, making disassembly and installation simple.

[0027] The activated carbon box 9 includes a placement tube 17 for holding the activated carbon 12. An annular groove 18 is formed at the open end of the placement tube 17, and a matching mounting ring 19 is inserted into the annular groove 18. A sealing disc 20 for sealing the opening of the placement tube 17 is fixedly connected to the mounting ring 19. Several drainage holes 21 are formed through the end face of the sealing disc 20 and the inner end face of the placement tube 17. The sealing disc 20 seals the placement tube 17 to prevent the activated carbon 12 from overflowing from the placement tube 17, and the drainage holes 21 ensure the normal passage of water.

[0028] A limiting ring 22 for placing the second mounting ring 10 is installed at the lower end of the inner side wall of the filter tank 6. In this embodiment, the limiting ring 22 ensures the stable placement of the filter mechanism inside the filter tank 6.

[0029] The connector includes several connecting frames 23 that are slidably installed on the bottom surface of the sealing cover 7 at uniform circumferential intervals. A movable insert 24 is fixedly installed on the bottom surface of the connecting frame 23. A drive rod 25 is hinged to the upper end of the side wall of the connecting frame 23. A drive disk 26 is hinged to the end of the drive rod 25 away from the connecting frame 23. The drive disk 26 is movably installed at the center of the bottom surface of the sealing cover 7 via a drive shaft 27. The drive shaft 27 passes through the sealing cover 7. A tension spring 28 is connected between the drive disk 26 and the bottom surface of the sealing cover 7. The tension spring 28 is sleeved on the drive shaft 27. A connecting ring groove 29 matching the movable insert 24 is opened at the upper end of the inner side wall of the first mounting ring 8.

[0030] A drive handle 30 is provided on the bottom surface of the sealing cover 7, and a pressing cover plate 31 is slidably mounted on the drive handle 30. The pressing cover plate 31 is fixedly connected to the drive shaft 27. In this embodiment, the drive handle 30 facilitates the installation and removal of the sealing cover 7 and the filter tank 6, and the pressing cover plate 31 facilitates the removal of the sealing cover 7 and the filter mechanism.

[0031] A water supply valve 32 is installed on the heating vaporization device 4. In this embodiment, the water supply valve 32 facilitates the addition of water to the heating vaporization device 4. The heating vaporization device is used to sterilize the condensate at high temperature.

[0032] The end of the movable insert 24 furthest from the connecting frame 23 is inclined. In this embodiment, the inclined end of the movable insert 24 furthest from the connecting frame 23 facilitates the installation of the sealing cover 7 and the filter mechanism.

[0033] The following are preferred embodiments of the biological instrument condensate recycling device to clearly illustrate the content of the present invention. It should be understood that the content of the present invention is not limited to the following embodiments, and other improvements made by conventional technical means by those skilled in the art are also within the scope of the present invention.

[0034] This invention provides a method for using a biological instrument condensate recycling device, the specific method of which is as follows:

[0035] S1. Multi-stage filtration and purification of condensate: The condensate generated by the instrument body 1 enters the filter tank 6 through the drain outlet from the inlet at the top of the filter tank 6. The condensate first passes through the fiber filter screen 11 to filter out larger particles of impurities, then enters the activated carbon box 9, where it undergoes effective decolorization and removal treatment by the activated carbon 12. Finally, the condensate passes through the vacuum ultrafiltration membrane 13 to filter out smaller particles of impurities such as suspended solids, and is stored in the filter tank 6.

[0036] S2. Reuse of condensate: When the instrument body 1 needs to be humidified, the condensate obtained by filtration and purification in the filter tank 6 is introduced into the heating vaporization device 4 by the return pump 3. The heating vaporization device 4 is heated to above 180°C to sterilize and vaporize the condensate. The vaporized condensate is then transported to the instrument body 1 for reuse by the steam pipe accompanied by the circulating air under the action of the circulating fan 5.

[0037] S3. Regular Maintenance of the Device: After a period of use, impurities remaining on the fiber filter 11 and vacuum ultrafiltration membrane 13 may cause blockage, affecting the filtration effect. Continued cleaning and maintenance are necessary. The activated carbon 12 will also become less effective and needs replacement to ensure good filtration performance. When maintaining the filter mechanism, first rotate the drive handle 30 to disengage the threads of the sealing cover 7 from the threads of the filter canister 6. Then, lift the drive handle 30 to remove the filter mechanism from the filter canister 6. Finally, press down... Under the action of the drive rod 25, the pressure plate 31 drives the connecting frame 23 to move inward to the sealing cover 7, so as to separate the movable insert 24 from the connecting ring groove 29. Since the first mounting ring 8 and the second mounting ring 10 are connected by magnetic adsorption, they can be quickly disassembled. After the first mounting ring 8 and the second mounting ring 10 are disassembled, the activated carbon box 9 is taken out. The fiber filter 11 on the first mounting ring 8 and the vacuum ultrafiltration membrane 13 on the second mounting ring 10 are cleaned and maintained respectively. The sealing plate 20 is opened, and the activated carbon 12 in the activated carbon box 9 can be replaced.

[0038] S4. Periodic water replenishment of the device: After long-term use, the circulating water will decrease to a certain extent, and water replenishment is required. When replenishing water, first connect the water replenishment valve 32 to the external water source, and then open the water replenishment valve 32 to allow the external pure water source to enter the heating and vaporization device 4.

[0039] In summary, the present invention has the following advantages over the prior art:

[0040] (1) This invention filters and purifies the condensate generated by the biological instrument through a filter, and sterilizes the filtered and purified condensate at high temperature with a heating vaporization device. The condensate is then transported back to the biological instrument by a circulating fan. This realizes the recycling of the condensate generated by the biological instrument after filtration, purification and sterilization, which improves the utilization rate of water resources, eliminates the need to regularly dump the condensate, reduces unnecessary trouble, and ensures a good experimental environment.

[0041] (2) The filter of the present invention adopts three layers of filtration: fiber screen, activated carbon and vacuum ultrafiltration membrane. The filtration effect is excellent. At the same time, the fiber screen, activated carbon and vacuum ultrafiltration membrane are easy to install and disassemble, which greatly facilitates the regular maintenance and replacement of the fiber screen, activated carbon and vacuum ultrafiltration membrane, thereby ensuring the good filtration effect of the filter.

[0042] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
