Description

Technical Field

[0001] The present application relates to the technical field of wastewater treatment, and in particular to a device for disinfecting live poison wastewater from an animal laboratory. Background Art

[0002] Animal laboratories are places for conducting animal simulation experiments to study biology, medicine, pharmacy and other fields. Since animal laboratories need to use various drugs and organic solvents for experiments, a large amount of polluted wastewater containing organic matter, bacteria and viruses will be generated. In order to achieve environmental protection and prevent the impact of water pollution agents on the environment, it is necessary to set up special animal laboratory live poison wastewater disinfection equipment; there are many processes for the disinfection of live poison wastewater in animal laboratories. Among them, the use of ultraviolet light sterilization is a relatively efficient and balanced method. Ultraviolet light disinfection mainly uses ultraviolet rays with a wavelength of 253.7nm at a temperature of 20~40℃. The maximum radiation intensity can be generated in the environment, and the best sterilization and disinfection effect can be achieved. In the prior art, for example, the patent with application number CN202410977891.X discloses a live poison wastewater disinfection system for animal laboratories. In order to reduce the impact of long-term low temperature of wastewater in the pipeline on the ultraviolet lamp, an electric heating wire is added to maintain the optimal working temperature of the ultraviolet lamp. However, the use of the electric heating wire is obviously not reliable enough. Under the action of the temperature sensor, the electric heating wire automatically controls heating or power off, wasting electric energy. The ultraviolet lamp consumes a lot of energy when working.

[0008] Preferably, the inner wall of the support plate is provided with a group of annular partitions, and the surface of the annular partitions is provided with multiple groups of ventilation grooves. Multiple groups of fixed cylinders are fixedly installed at equal angles on the surface of the annular partitions and are staggered with the ventilation grooves.

[0013] Preferably, the heat conducting sheet is wrapped around the bottom of the outer surface of the ultraviolet lamp tube, and the inner cavity of the supporting plate is communicated with the inner cavity of the sealing cylinder.

[0014] The beneficial effects of the present invention are as follows: 1. First, the device utilizes a top box, a bottom box and a connecting cylinder installed in the inner cavity of the box to form a disinfection assembly, wherein a sealing cylinder is installed inside the bottom box to isolate the wastewater in the connecting cylinder from the inside of the connecting cylinder, and the sealing cylinder is completely immersed in the wastewater in the inner cavity of the connecting cylinder, and the ultraviolet lamp is installed through a supporting plate so that the ultraviolet lamp is arranged in the sealing cylinder. After power is turned on, the ultraviolet lamp can emit ultraviolet rays to the inner cavity of the connecting cylinder to disinfect and sterilize the wastewater, and multiple groups of connecting pipes are used to allow the wastewater from the transfer box and the water inlet pipe to enter the interior of the top box along the tangent of the top box, and the rotating shaft and the friction sleeve are driven to rotate by pushing the rotating plate, so that the friction sleeve and the friction plate generate heat by friction, and the heat is transferred to the inside of the sealing cylinder through the ventilation groove, thereby first converting the kinetic energy of the wastewater flow into heat for maintaining the normal working temperature of the ultraviolet lamp, realizing the internal circulation of the wastewater kinetic energy, and greatly reducing the energy consumption and structural complexity of the device.

[0015] 2. Then, multiple groups of connecting pipes are installed on the tangential part of the outer surface of the top box, so that the wastewater entering the top box along the connecting pipe forms a vortex and gradually flows downward along the inside of the connecting cylinder, so that the wastewater can offset the kinetic energy consumed by the rotating plate under the help of gravity. At the same time, the wastewater spirals downward along the inner wall of the connecting cylinder under the action of the connecting pipe, thereby driving the scraper installed on the outer surface of the sealing cylinder to rotate and synchronously scrape the outer surface of the sealing cylinder. Since the inner wall of the scraper is adapted to abut against the outer surface of the sealing cylinder, the scraper on the outer surface of the sealing cylinder can continue to rotate, scrape off impurities on the surface of the sealing cylinder, avoid impurities in the wastewater covering the sealing cylinder, improve light transmittance, and enable the ultraviolet rays emitted by the ultraviolet lamp to completely cover the wastewater inside the connecting cylinder, thereby improving the disinfection ability of the device.

[0016] 3. Finally, the device is also provided with a temperature-sensing brake assembly inside the support disk, which includes a fixed cylinder, a heat-conducting column, a heat-conducting plate, a spring 1, a telescopic column, an abutting cylinder, a spring 2, and a friction plate to control the temperature of the inner cavity of the sealing cylinder. By installing multiple sets of fixed cylinders on the inner wall of the support disk, and movably sleeve the telescopic column and the spring 1 inside the fixed cylinder, the inner cavity of the fixed cylinder is filled with thermal expansion liquid, and the temperature in the inner cavity of the sealing cylinder and the support disk is sensed by the heat-conducting column and the heat-conducting plate, and then the abutting cylinder and the spring 2 are movably sleeved on the outer end of the telescopic column, so that the elastic force generated by the spring 2 puts pressure on the abutting cylinder and the friction plate to ensure that the friction sleeve is in close contact with the friction plate. As the friction sleeve rotates and slides and rubs with the friction plate, heat is continuously generated, and the inner cavity of the support disk and the sealing cylinder Heat is generated and gradually increases in temperature. On the one hand, the heat is absorbed by the room-temperature wastewater on the outer surface of the sealing cylinder, and on the other hand, it is absorbed by the heat-conducting column and the heat-conducting plate. Since the room-temperature wastewater on the outer surface of the sealing cylinder continuously absorbs heat, the heat inside the support plate and the sealing cylinder will be continuously absorbed. The heat-conducting column and the heat-conducting plate absorb less heat, and slow down the expansion rate of the thermal expansion liquid in the inner cavity of the fixed cylinder, so that the telescopic column can slowly move toward the axis of the friction sleeve, and always maintain the heat-generating function of the relative sliding of the friction sleeve and the friction plate. When the temperature is too high, the telescopic column continuously applies pressure to the second spring, and the pressure of the friction plate on the friction sleeve is too large, thereby generating a large friction force, forcing the friction sleeve and the rotating shaft to stop, and avoiding the ultraviolet lamp from being at too high an operating temperature.

[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] See also Figures 1-13 This embodiment discloses an animal laboratory live poison wastewater disinfection device, comprising: The box body 1 has a transfer box 2 and a water inlet pipe 3 installed on the top of the box body 1, and a transfer cavity 5 is opened at the bottom of the inner wall of the box body 1; A disinfection assembly includes a top box 7 and a bottom box 8, a connecting cylinder 10 is fixedly installed between the top box 7 and the bottom box 8, a support plate 9 is fixedly installed on the bottom of the inner wall of the box body 1, a rotating shaft 11 is rotatably installed on the inner wall of the support plate 9, the bottom box 8 and the top box 7, a rotating plate 12 is fixedly installed on the top of the outer surface of the rotating shaft 11, a plurality of groups of sealing cylinders 14 are fixedly installed on the bottom of the inner wall of the bottom box 8, a plurality of groups of ultraviolet lamps 15 extending upward to the inner wall of the sealing cylinder 14 are fixedly installed on the inner wall of the support plate 9, a plurality of groups of siphon tubes 18 are fixedly connected to the outer edge of the inner cavity of the bottom box 8, and the siphon tubes 18 are communicated with the transfer chamber 5; Multiple groups of fixed cylinders 20 are fixedly installed inside the support plate 9. The inner cavity of the fixed cylinder 20 is movably connected with a telescopic column 24 and a spring 1 23. A heat-conducting column 21 is installed through the middle of the fixed cylinder 20. The inner cavity of the fixed cylinder 20 is filled with a thermal expansion liquid. The outer end of the telescopic column 24 is movably connected with a spring 26 and an abutment cylinder 25. One end of the abutment cylinder 25 is fixedly connected to a friction plate 27. The friction sleeve 13 is fixedly installed on the bottom of the outer surface of the rotating shaft 11. The friction plate 27 is adapted to abut the outer surface of the friction sleeve 13. The device utilizes the kinetic energy generated by the flow of wastewater and converts it into internal energy to maintain the normal operating temperature of the ultraviolet lamp 15, realizing the internal circulation function of the wastewater kinetic energy and the ultraviolet disinfection environment, greatly reducing the energy consumption and structural complexity of the device.

[0022] First, the device uses a top box 7, a bottom box 8 and a connecting tube 10 installed in the inner cavity of the box body 1 to form a disinfection assembly, wherein a sealing tube 14 is installed inside the bottom box 8 to isolate the wastewater in the connecting tube 10 from the inside of the connecting tube 10, and the sealing tube 14 is completely immersed in the wastewater in the inner cavity of the connecting tube 10, and an ultraviolet lamp 15 is installed through the support plate 9 so that the ultraviolet lamp 15 is set in the sealing tube 14. After power is turned on, the ultraviolet lamp 15 can emit ultraviolet rays into the inner cavity of the connecting tube 10 to disinfect the wastewater. , sterilization operation, using multiple groups of connecting pipes 6 to allow the wastewater from the transfer box 2 and the water inlet pipe 3 to enter the interior of the top box 7 along the tangent of the top box 7, and by pushing the rotating plate 12 to drive the rotating shaft 11 and the friction sleeve 13 to rotate, so that the friction sleeve 13 and the friction plate 27 generate heat through friction, and the heat is transferred to the inside of the sealing cylinder 14 through the ventilation groove 19, so as to first convert the kinetic energy of the wastewater flow into heat to maintain the normal working temperature of the ultraviolet lamp tube 15, thereby realizing the internal circulation of the wastewater kinetic energy and greatly reducing the energy consumption and structural complexity of the device.

[0023] The present device is also provided with a temperature-sensing brake assembly inside the support disk 9, which includes a fixed cylinder 21, a heat-conducting column 22, a heat-conducting plate 23, a spring 1 24, a telescopic column 25, an abutting cylinder 26, a spring 27, and a friction plate to control the temperature of the inner cavity of the sealing cylinder 14. By installing multiple sets of fixed cylinders 20 on the inner wall of the support disk 9, and movably sleeve the telescopic column 24 and the spring 1 23 inside, the inner cavity of the fixed cylinder 20 is filled with a thermal expansion liquid, and the temperature in the inner cavity of the sealing cylinder 14 and the support disk 9 is sensed by the heat-conducting column 21 and the heat-conducting plate 22, and then the abutting cylinder 25 and the spring 2 26 are movably sleeved on the outer end of the telescopic column 24, so that the elastic force generated by the spring 26 applies pressure to the abutting cylinder 25 and the friction plate 27 to ensure that the friction sleeve 13 is in close contact with the friction plate 27. As the friction sleeve 13 rotates and slides and rubs with the friction plate 27, heat is continuously generated, and the support disk 9 and the sealing cylinder 14 are in close contact. The inner cavity of the cylinder 14 generates heat and gradually heats up. On the one hand, the heat is absorbed by the room-temperature wastewater on the outer surface of the sealing cylinder 14, and on the other hand, it is absorbed by the heat-conducting column 21 and the heat-conducting plate 22. Since the room-temperature wastewater on the outer surface of the sealing cylinder 14 continues to absorb heat, the heat inside the support plate 9 and the sealing cylinder 14 will be continuously absorbed. The heat-conducting column 21 and the heat-conducting plate 22 absorb less heat, and slow down the expansion rate of the thermal expansion liquid in the inner cavity of the fixed cylinder 20, so that the telescopic column 24 can slowly move toward the axis of the friction sleeve 13 and always maintain the heat-generating function of the relative sliding of the friction sleeve 13 and the friction plate 27. When the temperature is too high, the telescopic column 24 continues to apply pressure to the spring 26, and the friction plate 27 exerts too much pressure on the friction sleeve 13, thereby generating a large friction force, forcing the friction sleeve 13 and the rotating shaft 11 to stop, thereby preventing the operating temperature of the ultraviolet lamp tube 15 from being too high.

[0024] Among them, the right side of the bottom of the box body 1 is provided with a water outlet pipe 4 connected to the transfer chamber 5, and the bottom of the transfer box 2 is fixedly connected to multiple groups of connecting pipes 6, one end of the multiple groups of connecting pipes 6 is connected to the top box 7 along the tangent line of the top box 7; The transfer chamber 5 is connected to the siphon tube 18. When the treated wastewater from the connecting tube 10 and the siphon tube 18 flows through the transfer chamber 5, it will flow downward through the outlet pipe 4. Through multiple groups of connecting tubes 6 installed on the tangent part of the outer surface of the top box 7, the wastewater entering the top box 7 along the connecting tubes 6 will form a vortex and gradually flow downward along the inside of the connecting tube 10, so that the wastewater can offset the kinetic energy consumed by the rotating plate 12 under the help of gravity.

[0025] The connecting tube 10, sealing tube 14, and siphon tube 18 are all made of transparent glass. The top box 7 is fixedly mounted on the bottom of the transfer box 2, and the bottom box 8 is fixedly mounted on the top of the support plate 9. A support column 16 is provided on the top of the sealing tube 14. A scraper 17 is movably sleeved on the outer surface of the sealing tube 14 through the support column 16. The inner wall of the scraper 17 is adapted to abut against the outer surface of the sealing tube 14. The connecting tube 10, the sealing tube 14 and the siphon tube 18 all have high light transmittance. This design facilitates the ultraviolet light emitted by the ultraviolet lamp 15 to completely cover the wastewater inside the connecting tube 10. By installing multiple groups of connecting pipes 6 on the tangential parts of the outer surface of the top box 7, the wastewater entering the top box 7 along the connecting pipes 6 forms a vortex and gradually flows downward along the inside of the connecting cylinder 10, so that the wastewater, under the help of gravity, offsets the kinetic energy consumed by the rotating plate 12. At the same time, the wastewater spirals downward along the inner wall of the connecting cylinder 10 under the action of the connecting pipes 6, thereby driving the scraper 17 installed on the outer surface of the sealing cylinder 14 to rotate and synchronously scrape the outer surface of the sealing cylinder 14. Since the inner wall of the scraper 17 is adapted to abut against the outer surface of the sealing cylinder 14, the scraper 17 on the outer surface of the sealing cylinder 14 can continue to rotate, scrape off impurities on the surface of the sealing cylinder 14, prevent impurities in the wastewater from covering the sealing cylinder 14, improve light transmittance, and enable the ultraviolet rays emitted by the ultraviolet lamp tube 15 to completely cover the wastewater inside the connecting cylinder 10, thereby improving the disinfection ability of the device.

[0026] The siphon tube 18 is U-shaped, with one end of the siphon tube 18 facing the bottom of the inner wall of the bottom box 8 and leaving a gap between the end and the bottom of the inner wall of the bottom box 8. The other end of the siphon tube 18 is connected to the transfer chamber 5. The height of the end of the siphon tube 18 connected to the transfer chamber 5 is lower than that of the end located on the inner wall of the bottom box 8. The U-shaped siphon tube 18 has a "U"-shaped end where the outer end connected to the transfer chamber 5 is lower than the end located inside the bottom box 8, which enables the siphon tube 18 to have a siphoning ability, thereby assisting in discharging wastewater from the bottom box 8 and the inner cavity of the connecting tube 10.

[0027] Among them, the inner wall of the support plate 9 is provided with a group of annular partitions, and the surface of the annular partitions is provided with multiple groups of ventilation grooves 19. Multiple groups of fixed cylinders 20 are fixedly installed at equal angles on the surface of the annular partitions and are staggered with the ventilation grooves 19. The inner cavity of the support plate 9 is divided into an outer ring 91 and an inner ring 92 by the annular partitions. The fixed cylinders 20 are located inside the outer ring 91, and the outer ring 91 and the inner ring 92 are connected through the ventilation grooves 19. like Figure 13As shown, the annular partition separates the inner cavity of the support plate 9 into an outer ring 91 and an inner ring 92. The fixed cylinder 20, the heat-conducting column 21 and the heat-conducting plate 22 are located inside the outer ring 91 and are responsible for sensing the temperature of the ultraviolet lamp 15 and the environment in which the ultraviolet lamp 15 is located. The friction sleeve 13 is located inside the inner ring 92. The rotating shaft 11 drives the friction sleeve 13 to rotate and generates heat through friction with the friction plate 27. The heat is transferred to the inner cavity of the outer ring 91 and the sealing cylinder 14 through the ventilation groove 19 to maintain the normal operating temperature of the ultraviolet lamp 15. Since the wastewater continues to absorb heat on the outer surface of the sealing cylinder 14, the heat acting on the heat-conducting column 21 and the heat-conducting plate 22 is less, which makes the heat in the inner cavity of the fixed cylinder 20 The expansion speed of the expansion liquid slows down during the normal working process, and the telescopic column 24 stretches the spring 26 to maintain the pressure of the abutment tube 25 and the friction plate 27 on the outer surface of the friction sleeve 13. When the working temperature of the sealing tube 14 is too high, the thermal expansion liquid in the inner cavity of the fixed tube 20 begins to expand rapidly, and eventually forces the telescopic column 24 to apply pressure to the abutment tube 25, and directly stops the friction sleeve 13 and the rotating shaft 11 by increasing the friction between the friction plate 27 and the friction sleeve 13. However, this situation basically does not exist during the service life of the friction sleeve 13 and the friction plate 27, because the wastewater in the connecting tube 10 will continue to absorb heat, reducing the temperature of the inner cavity of the sealing tube 14 and the support plate 9.

[0028] The thermal expansion liquid is made of mercury or kerosene, and the middle portion of the heat-conducting column 21 is wrapped in the thermal expansion liquid; The heat-conducting column 21 and the heat-conducting sheet 22 are responsible for sensing the temperature of the ultraviolet lamp 15 and the environment in which the ultraviolet lamp 15 is located. The heat-conducting column 21 conducts heat to the thermal expansion liquid in the inner cavity of the fixing cylinder 20 .

[0029] The spring 1 23 is movably sleeved on the outer surface of the telescopic column 24, and the two ends of the spring 1 23 are elastically connected to the telescopic column 24 and the fixed cylinder 20 respectively; like Figure 10 As shown, the spring 1 23 is responsible for driving the telescopic column 24 to move toward the inside of the fixed tube 20 toward the side of the heat conducting column 21 and reset.

[0030] The second spring 26 is movably sleeved on the outer surface of the telescopic column 24, and the two ends of the second spring 26 are elastically connected to the abutment tube 25 and the telescopic column 24 respectively; like Figure 10 As shown, the abutting tube 25 and the friction plate 27 abut against the friction sleeve 13 and generate a reaction force, causing the abutting tube 25 to move in the opposite direction relative to the telescopic column 24 and stretching the second spring 26 to keep the friction plate 27 in close contact with the friction sleeve 13.

[0031] The heat conducting columns 21 and the heat conducting sheets 22 are provided in multiple groups of the same number, and the multiple groups of heat conducting columns 21 and the multiple groups of heat conducting sheets 22 are welded end to end in a staggered manner. The heat conducting columns 21 and the heat conducting sheets 22 are both made of brass. like Figure 13 As shown, multiple groups of heat-conducting columns 21 and heat-conducting plates 22 are connected end to end, which is conducive to evenly transferring heat to multiple groups of fixed cylinders 20, keeping different friction plates 27 able to synchronously apply pressure to the outer surface of the friction sleeve 13, and improving the stability of the rotating shaft 11 and the friction sleeve 13.

[0032] The heat conducting sheet 22 is wrapped around the bottom of the outer surface of the ultraviolet lamp 15, and the inner cavity of the support plate 9 is connected to the inner cavity of the sealing cylinder 14; The heat conducting sheet 22 senses the temperature of the ultraviolet lamp 15 and the environment in which the ultraviolet lamp 15 is located, and promptly dissipates the heat to maintain the normal working environment temperature of the ultraviolet lamp 15 .

[0033] Working principle: When the device is working, first, the water inlet pipe 3 is connected to the water pump as the water inlet end of the device, and the water outlet pipe 4 is the water outlet end. The treatment water path inside the device is as follows: water inlet pipe 3, transfer box 2, connecting pipe 6, top box 7, connecting tube 10, bottom box 8, siphon tube 18, transfer chamber 5, water outlet pipe 4, and the ultraviolet lamp 15 is started; Then, the water pump pumps the wastewater into the transfer tank 2, so that the wastewater gradually fills the transfer tank 2 and generates positive pressure, such as Figure 6 As shown, the wastewater discharged into the top box 7 through the connecting pipe 6 enters the top box 7 along the tangential direction of the top box 7, thereby pushing the rotating plate 12, which drives the rotating shaft 11 and the friction sleeve 13 to rotate. The wastewater is guided by the tangent of the connecting pipe 6 to form a vortex in the inner cavity of the connecting cylinder 10. After the ultraviolet lamp 15 is turned on, it disinfects bacteria, viruses and other impurities in the wastewater. At the same time, the wastewater forms a vortex and flows downward in a spiral along the inner wall of the connecting cylinder 10, driving the scraper 17 to rotate around the outer surface of the sealing cylinder 14, thereby preventing impurities in the wastewater from adhering to the outer surface of the sealing cylinder 14 and improving the light transmittance of the ultraviolet rays emitted by the sealing cylinder 14. Then, the disinfected wastewater accumulates in the inner cavity of the bottom box 8. As the wastewater level inside the connecting tube 10 rises, the wastewater begins to enter the siphon tube 18 until it is higher than the highest point of the inner wall of the siphon tube 18, and then flows along the other end of the siphon tube 18 into the inner cavity of the transfer chamber 5, and is finally discharged from the outlet pipe 4. When the wastewater in the connecting tube 10 reduces the temperature of the inner cavity of the sealing tube 14, the rotating shaft 11 drives the friction sleeve 13 to rotate, so that the friction plate 27 slides and rubs against the friction sleeve 13 under the push of the telescopic column 24, the second spring 26 and the abutment tube 25. , and generates heat, which enters the inner cavity of the outer ring 91 and the sealing cylinder 14 along the ventilation groove 19. When the temperature of the inner cavity of the support plate 9 and the sealing cylinder 14 is too high, the heat-conducting column 21 and the heat-conducting plate 22 transfer the heat to the thermal expansion liquid in the fixed cylinder 20, causing it to expand and continuously push the telescopic column 24 outward, causing the telescopic column 24 to continuously enter the deep inside of the abutment cylinder 25, and by stretching the second spring 26, the abutment pressure between the abutment cylinder 25, the friction plate 27 and the friction sleeve 13 is increased, and finally a greater friction force is generated to stop the friction sleeve 13 and the rotating shaft 11.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
