Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a micro-wastewater treatment system for a biological laboratory. Background Technology

[0002] A biosafety laboratory, also known as a biological laboratory, is a place for conducting experiments related to biology. With increasingly stringent quality control requirements, its application areas are expanding. Most schools have biological laboratories, and hospital blood testing laboratories are also biosafety laboratories. People typically enter biological laboratories for learning and research. During biological experiments, wastewater is generated. Laboratory wastewater has a complex composition, mainly consisting of inorganic substances, organic substances, and biological wastewater. To reduce water pollution, biological laboratory wastewater is generally treated before discharge. Miniature equipment is commonly used for this treatment. Current technology for treating biological laboratory wastewater typically consists of a pH adjustment tank, a micro-electrolysis tank, a neutralization sedimentation tank, a filtration tank, and a disinfection tank. The filtration tank usually contains a filter screen for filtration. However, after prolonged use, impurities blocked by the filter screen tend to accumulate, leading to a high probability of filter clogging. This clogging hinders wastewater from passing through the filter screen, thus affecting the filtration effect.

[0003] The announcement number is CN219251778U, which discloses a micro-device for treating wastewater in biological laboratories. This wastewater treatment device uses a rotating conveyor belt to move multiple scrapers. The scrapers on the lower side move forward along a filter screen, cleaning it and pushing the filtered impurities forward. The impurities fall into a drawer, while residual water mixed with impurities falls through first and second drain holes into a sterilization tank. However, during filtration, the impurities soften after being soaked in liquid. When the scrapers push the impurities across the filter screen, they directly clog the filter pores. The wastewater treatment device lacks a component to clean these pores, meaning the filter screen becomes unusable after prolonged use. Furthermore, the drawer only has drain holes at the bottom, which become clogged when too much impurity accumulates, preventing wastewater from draining out.

[0004] Based on this, a micro-sewage treatment system for biological laboratories is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-6As shown, a micro-sewage treatment system for a biological laboratory includes a filter box 11, with a disinfection box 12 fixedly mounted at the bottom of the filter box 11. The filter box 11 is connected to the interior of the disinfection box 12 via a connecting pipe. The disinfection box 12 is fixedly mounted inside the bottom of an outer frame 13. A first liquid pump 17 is fixedly mounted at the upper end of the outer frame 13, with its output end extending into the filter box 11. A filter belt 21 is positioned inside the filter box 11 at a location corresponding to the lower position of the first liquid pump 17. A drive roller and a transmission roller are respectively fitted at both ends of the filter belt 21. The rotating shafts at both ends of the drive roller and the transmission roller are rotatably mounted inside a protective enclosure 22. The protective enclosure 22 is positioned outside the filter belt 21. The filter belt 21 is fixedly installed inside the filter box 11. One end of the filter belt 21 is tightly attached to the scraper 25. The scraper 25 is fixedly installed at one end of the protective enclosure 22. A collection hood 26 is provided inside the filter box 11 and below the scraper 25. A collection box 27 is tightly attached to the bottom of the collection hood 26. A limiting frame is slidably provided at the bottom of the collection box 27. The limiting frame is fixed inside the filter box 11. A cleaning mechanism for cleaning the filter belt 21 is provided inside the filter box 11. A squeezing mechanism for squeezing the impurities inside the collection box 27 is provided inside the filter box 11. The cleaning mechanism facilitates cleaning the filter holes on the filter belt 21. The squeezing mechanism facilitates squeezing and discharging the residual sewage in the impurities inside the collection box 27.

[0026] A drive shaft is fixedly mounted on one end of the drive roller's rotating shaft. One end of the drive shaft extends to the outside of the filter box 11. A first driven wheel is fixedly mounted on the drive shaft. The first driven wheel is connected to a first driving wheel via a first belt. The first driving wheel is fixedly mounted on the output end of the motor 23. The motor 23 is fixedly mounted on one side of the filter box 11. A handle is fixedly mounted on one side of the collection box 27. A rectangular perforation is provided on one side of the filter box 11 corresponding to the position of the collection box 27. A sealing door is fitted inside the rectangular perforation. In use, when it is necessary to filter sewage, the first liquid pump... The first pump 17 draws in wastewater to be filtered, and then discharges the wastewater onto the filter belt 21 from the output end of the first pump 17. Several filter holes on the filter belt 21 can filter the wastewater, so that impurities in the wastewater are intercepted at the upper end of the filter belt 21. At the same time, the motor 23 is started, and the output end of the motor 23 drives the drive roller to rotate. The drive roller and the transmission roller work together to drive the filter belt 21 to rotate. When the impurities follow the filter belt 21 to one end of the filter belt 21, the impurities fall into the collection box 27 for collection. The impurities attached to the filter belt 21 are scraped off by the scraper 25 and fall into the collection box 27.

[0027] The cleaning mechanism includes a first cleaning pipe 28, which is fitted inside the filter belt 21. The bottom end of the first cleaning pipe 28 has several first vent holes. The bottom end of the first cleaning pipe 28 is in close contact with the bottom end of the filter belt 21. The first cleaning pipe 28 is fixedly installed inside the filter box 11. The input end of the first cleaning pipe 28 is connected to the output end of an external air supply component. A baffle plate 24 is provided above the first cleaning pipe 28 and is fixedly installed inside the filter box 11. A material receiving device is located at the bottom end of the filter belt 21, corresponding to the position of the first cleaning pipe 28. The receiving plate is fixed inside the filter box 11 and is inclined. In use, after the filter belt 21 filters the sewage, the sewage falls onto the upper end of the baffle plate 24. The baffle plate 24 guides the sewage so that it falls into the bottom of the filter box 11. When the filter belt 21 moves to the bottom of the first cleaning pipe 28 after being scraped and cleaned by the scraper 25, the external air supply component supplies gas into the first cleaning pipe 28. The gas is discharged through the first exhaust hole, which back-blown the filter holes on the filter belt 21 and cleans several filter holes on the filter belt 21.

[0028] The extrusion mechanism includes an extrusion plate 29, which is disposed above the collection box 27. The extrusion plate 29 is fixedly connected to the output ends of several spring telescopic rods 30. Each of the spring telescopic rods 30 is fixedly disposed at the bottom end of a sliding plate. Limiting grooves 32 are slidably provided at both ends of the sliding plate and are fixedly disposed inside the filter box 11. A guide groove 33 is fixedly provided on one side of the sliding plate, and a guide slide groove is provided on one side of the guide groove 33. A limiting post is slidably provided in the guide slide groove and is fixedly disposed on one side of a rotating ring 34. A fixed ring is rotatably provided on the rotating ring 34 and is fixedly disposed inside the filter box 11. A first mounting shaft is fixedly provided on one side of the rotating ring 34, and a first bevel gear is fixedly provided on the first mounting shaft. A second bevel gear meshes with the first bevel gear and is fixedly disposed on the second bevel gear. A rotating frame is rotatably mounted on a second mounting shaft, which is fixed inside the filter box 11. One end of the second mounting shaft extends to the outside of the filter box 11, and the other end of the second mounting shaft is fixed with a second driven wheel. The second driven wheel is connected to a second driving wheel via a second belt. The second driving wheel is fixed on the output end of the motor 23. In use, when the output end of the motor 23 rotates, the output end of the motor 23 drives the second mounting shaft to rotate, and the second mounting shaft drives the rotating ring 34 to rotate. The rotating ring 34 cooperates with the guide groove through a limiting post, so that the guide groove rod 33 drives the sliding plate to move back and forth. The sliding plate drives the squeezing plate 29 to move through several spring telescopic rods 30, so that when the limiting post rotates to the lowest position, the squeezing plate 29 squeezes the impurities inside the collection box 27, thereby squeezing out the residual sewage in the impurities.

[0029] A compression sensor 31 is fixedly installed inside the spring telescopic rod 30. The compression sensor 31 is electrically connected to an external control component. A compression rod is provided at the output end of the spring telescopic rod 30 corresponding to the position of the compression sensor 31. In use, when too many impurities are collected inside the collection box 27, the compression plate 29 compresses the impurities inside the collection box 27, and the output end of the spring telescopic rod 30 retracts, causing the compression rod to compress the compression sensor 31. The compression sensor 31 is electrically connected to the external control component, which reminds the staff to clean the impurities inside the collection box 27. It is worth noting that the compression sensor 31 and the external control component in this application are both existing components, and the connection method, internal structure, and working principle are all common knowledge and will not be described in detail here.

[0030] A fixing plate is fixedly provided on the upper end of the collection hood 26. A second cleaning pipe 35 is fixedly provided on one side of the fixing plate. A plurality of second exhaust holes and third exhaust holes are arranged in an array on one side of the second cleaning pipe 35. The input end of the second cleaning pipe 35 is connected to the output end of the external air supply component. The second exhaust hole is inclined. In use, when the extrusion plate 29 extrudes the impurities inside the collection box 27, some impurities will adhere to the bottom end of the extrusion plate 29. When the extrusion plate 29 returns to its initial position after extrusion, the external air supply component supplies gas into the second cleaning pipe 35. The second cleaning pipe 35 discharges the gas through the second exhaust hole and the third exhaust hole, so that when the extrusion plate 29 passes through the second cleaning pipe 35, the gas can clean the impurities attached to the extrusion plate 29, so that the impurities fall back into the collection box 27.

[0031] A sedimentation tank 14, a micro-electrolysis tank 15, and a pH adjustment tank 16 are sequentially arranged on one side of the filter box 11. The sedimentation tank 14, micro-electrolysis tank 15, and pH adjustment tank 16 are all fixedly installed inside the outer frame 13. A second liquid pump 18, a third liquid pump 19, and a fourth liquid pump 20 are respectively installed at positions corresponding to the sedimentation tank 14, micro-electrolysis tank 15, and pH adjustment tank 16 on the upper end of the outer frame 13. The output end of the fourth liquid pump 20 is connected to the interior of the pH adjustment tank 16. The micro-electrolysis tank 15 and the pH adjustment tank 16 are connected by the third liquid pump 18. Pump 19 is connected, and the sedimentation tank 14 and the micro-electrolysis tank 15 are connected via a second liquid pump 18. The disinfection tank 12 is equipped with a disinfection component and a drain pipe is connected inside the disinfection tank 12. In use, wastewater containing inorganic matter, organic matter, and biological substances generated by the biological laboratory is transported to the pH adjustment tank 16 via a fourth liquid pump 20. At the same time, the pH data of the wastewater in the pH adjustment tank 16 is collected by a pH meter on the pH adjustment tank 16. Based on the meter signal, acid and alkali are automatically added to the pH adjustment tank 16 to adjust the pH. The pH value of the wastewater in the equalization tank 16 is adjusted to between 6.5 and 7.5. The pH-adjusted wastewater is then pumped to the micro-electrolysis tank 15 via the third liquid pump 19. Here, numerous tiny galvanic cells are formed within the micro-electrolysis tank 15 using iron-carbon electrodes, oxidizing the iron in the wastewater to produce ferrous coagulant. This coagulant effectively removes metal ions and other weakly negatively charged particles. The electrolyzed wastewater is then pumped to the neutralization sedimentation tank 14 via the second liquid pump 18. In the neutralization sedimentation tank 14, PAC and PAM are added to neutralize and settle the sediment. Metal ions in the wastewater in the sedimentation tank 14 precipitate and flocculate, thus completing the separation of mud and water. Then, the supernatant in the neutralization sedimentation tank 14 is transported to the filter tank 11 by the first liquid pump 17, and the supernatant is filtered by the filter belt 21 in the filter tank 11. The filtered supernatant then falls into the disinfection tank 12, where it is disinfected to complete the deep treatment and meet the discharge standards. The pH adjustment tank 16, the micro-electrolysis tank 15, the neutralization sedimentation tank 14, the filter tank 11, and the disinfection tank 12 are all existing publicly available technologies.

[0032] The above embodiments disclose a micro-wastewater treatment system for a biological laboratory. Wastewater containing inorganic matter, organic matter, and biological components generated by the biological laboratory is pumped into a pH adjustment tank 16 via a fourth liquid pump 20. Simultaneously, a pH meter on the pH adjustment tank 16 collects pH data of the wastewater. Based on the meter signal, acid and alkali are automatically added to the pH adjustment tank 16 to achieve a pH value between 6.5 and 7.5. The pH-adjusted wastewater is then pumped through a third liquid pump... Pump 19 delivers the wastewater to the micro-electrolysis tank 15, where iron-carbon electrodes create numerous tiny galvanic cells. This oxidizes the iron in the wastewater, producing ferrous coagulant, which removes metal ions and other weakly negatively charged particles. The electrolyzed wastewater is then pumped to the neutralization sedimentation tank 14 via a second liquid pump 18. In the neutralization sedimentation tank 14, PAC and PAM are added to precipitate and flocculate the metal ions, thus completing the sludge-water separation. The wastewater is then discharged from the neutralization sedimentation tank. The supernatant in filter 14 is pumped into filter box 11 by first pump 17. The output of first pump 17 discharges wastewater above filter belt 21. Several filter holes on filter belt 21 filter the wastewater, trapping impurities at the top. Simultaneously, motor 23 is started, driving a drive roller to rotate. The drive roller, in conjunction with transmission roller, rotates filter belt 21. When impurities move along filter belt 21 to one end, they fall into collection box 27 for collection. Impurities on the filter belt 21 are scraped off by the scraper 25 and fall into the collection box 27. Sewage falls onto the upper end of the baffle plate 24. The baffle plate 24 guides the sewage to fall into the bottom of the filter box 11. When the filter belt 21 moves to the bottom of the first cleaning pipe 28 after being scraped and cleaned by the scraper 25, the external air supply component supplies gas into the first cleaning pipe 28. The first cleaning pipe 28 discharges gas through the first exhaust hole, which back-blown the filter holes on the filter belt 21 and cleans several filter holes on the filter belt 21.

[0033] Simultaneously, when the output end of the motor 23 rotates, the output end of the motor 23 drives the second mounting shaft to rotate, and the second mounting shaft drives the rotating ring 34 to rotate. The rotating ring 34 cooperates with the guide groove through the limiting post, so that the guide groove rod 33 drives the sliding plate to move back and forth. The sliding plate drives the squeezing plate 29 to move through several spring telescopic rods 30, so that when the limiting post rotates to the lowest position, the squeezing plate 29 squeezes the impurities inside the collection box 27, so that the residual sewage in the impurities is squeezed out. After the squeezing plate 29 squeezes the impurities inside the collection box 27, some impurities will adhere to the bottom of the squeezing plate 29. When the squeezing plate 29 returns to the initial position after squeezing, the external air supply component delivers gas into the second cleaning pipe 35. The second cleaning pipe 35 discharges the gas through the second exhaust port and the third exhaust port, so that when the squeezing plate 29 passes through the second cleaning pipe 35, the gas can clean the impurities attached to the squeezing plate 29, so that the impurities fall back into the collection box 27. Then the sewage flows into the disinfection box 12 for disinfection treatment.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
