The soft endoscope cleaning wastewater purification and recycling equipment comprises a filter bin, two conical filter cartridges which are horizontally arranged in the filter bin and can rotate around the horizontal axes thereof and are used for dynamically filtering the inflowing cleaning wastewater, and arc-shaped filter plates. The conical filter cartridges are composed of a plurality of arc-shaped filter plates which are uniformly distributed in the circumferential direction and are hinged. The large-diameter end of each arc-shaped filter plate is a rotating section, and the small-diameter end is a fixed section. When the arc-shaped filter plate rotates to the upper position of the filter bin, the rotating section can be turned over by 180 DEG relative to the fixed section, so that the filtering surface originally facing the inner side is turned to the outer side. By arranging a pair of horizontally-opposed and synchronously-rotating conical filter cartridges in the filter bin, the filter hole blockage can be effectively prevented by using the dynamic surface, and the interception capacity can be significantly strengthened by means of the rotating centrifugal effect.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, in particular to a purification and reuse equipment for soft endoscope cleaning wastewater. BACKGROUND

[0002] The soft endoscope is a bendable medical device commonly used for examination and treatment of digestive tract, respiratory tract and other body cavities. The cleaning wastewater of the soft endoscope is mainly derived from blood, tissue debris, pathogens and disinfectants and other pollutants remaining on the surface and in the pipeline of the endoscope after diagnosis and treatment, which are discharged with water flow during the cleaning process. Such wastewater contains high concentration of organic matter and potential pathogenic microorganisms, and if directly discharged without treatment, it may cause environmental pollution or cross-infection risk. For the purification and reuse of such wastewater, pollutants are usually removed through processes such as pre-filtration, adjustment and neutralization, and disinfection and sterilization, so as to meet the safe discharge or reuse standards.

[0003] However, the existing purification and reuse equipment still has the following problems in the process of treating the cleaning wastewater:

[0004] 1. The integrated fixed filter plate or filter screen commonly used in the prior art is prone to form a dense filter cake layer on the filter surface when treating the cleaning wastewater in the face of complex pollutants such as blood clots, tissue debris and high-viscosity organic matter. Since the filter plate structure is fixed, the filter surface cannot be actively exposed, and only external scrapers or high-pressure flushing can be relied on for cleaning, which makes it difficult to completely remove the attached pollutants. With the continuous accumulation of filter cake, the filter holes are gradually blocked, the filtration flux is significantly reduced, the treatment efficiency is lowered, and in addition, manual intervention is usually required to complete effective slag removal, which not only consumes time and effort, but also disrupts the continuity of the filtration process.

[0005] 2. The neutralizing agent is usually added by relying on water flow negative pressure siphon method. When the flow rate of the cleaning wastewater is low, the neutralizing agent and the wastewater are difficult to mix thoroughly, and stratified flow is easily formed: the concentration of the neutralizing agent is too high in the center area of the pipeline, and the dosage is insufficient near the pipe wall, which leads to incomplete local neutralization or waste of the agent, and further affects the treatment effect of the subsequent neutralization and disinfection processes.

[0039] In the following, according to Figures 1-14 The soft endoscope cleaning wastewater purification and reuse equipment provided by the embodiment of the present application is described.

[0040] Please refer to Figure 1 and Figure 2 , the soft endoscope cleaning wastewater purification and reuse equipment, comprising a device body 1, a plurality of cleaning tanks are arranged on the device body 1 in sequence, respectively used for primary washing, enzyme washing, rinsing and final rinsing and other processes, to clean the soft endoscope in stages, a drainage port is arranged at the bottom of each cleaning tank, so that the cleaning wastewater is naturally collected under the action of gravity, the drainage ports of all cleaning tanks are connected downward to the same collection pipeline 11 through a pipeline, the collection pipeline 11 is horizontally laid in the installation cabinet at the lower part of the device body 1, used for collecting and guiding all cleaning wastewater, and directly transported to the purification treatment unit also integrated in the installation cabinet, to realize on-site collection and on-site treatment of wastewater.

[0041] The purification treatment unit mainly comprises a pre-filtering module, an adjusting and neutralizing module, a disinfecting and sterilizing module and a reuse water tank 3, and the disinfecting and sterilizing module can be selected from the existing equipment. Among them, the pre-filtering module is arranged at the wastewater inlet, used for intercepting tissue debris, blood clots, cotton fibers, hairs and particulate impurities falling off during the cleaning process of the soft endoscope, to prevent large particles from entering the subsequent modules to cause blockage or wear.

[0042] Specifically, please refer to Figure 2 , Figure 3 and Figure 5 , the pre-filtering module comprises a filtering bin 2, the filtering bin 2 is fixedly arranged in the installation cabinet, the filtering bin 2 is connected with the collection pipeline 11, the cleaning wastewater flows into the filtering bin 2 through the collection pipeline 11 to perform preliminary solid-liquid separation, two left-right symmetrical and horizontally arranged conical filter cartridges 21 are rotatably arranged inside the filtering bin 2, each conical filter cartridge 21 can continuously rotate around its own horizontal axis, during operation, the conical filter cartridges 21 continuously rotate, on the one hand, the dynamic surface is updated to avoid filter hole blockage, on the other hand, the centrifugal effect generated by rotation makes the tissue debris, mucus and small particulate matters in the wastewater more closely adhere to the inner wall of the conical filter cartridges 21, to enhance the interception effect, thereby realizing efficient and continuous solid-liquid separation.

[0043] Please refer to Figures 2-5, the whole filter bin 2 is composed of two left and right conical cavities and a middle annular transition cavity, forming a symmetrical flow channel structure, and an upper end of the filter bin 2 is provided with a water inlet pipe 12 in communication with a collecting pipe 11, for guiding the cleaning wastewater into the filter bin 2, and a flow distribution conical block 22 is fixedly installed between the left and right conical filter cartridges 21 inside the filter bin 2, and two filter spaces are respectively formed between the flow distribution conical block 22 and the inner walls of the two conical filter cartridges 21, after the cleaning wastewater enters through the water inlet pipe 12, it is first guided by the flow distribution conical block 22 and is evenly divided into two water flows, which respectively enter the corresponding filter spaces, so as to effectively balance the hydraulic load and reduce the local flow velocity, avoiding the impact or short flow of high-speed water flow on the filter cartridge, and ensuring the stable and efficient filtration process.

[0044] In addition, please refer to Figures 5-7 and Figure 12 , a water outlet space is arranged between the bottom of the filter bin 2 and the outer wall of the conical filter cartridge 21, the space is small in height, forming a narrow water collecting channel, and the clean water filtered by the conical filter cartridge 21 is collected in the water outlet space under the action of gravity and rotation centrifugal force, and is discharged through a water outlet 23 arranged below the bottom of the filter bin 2, so as to complete the solid-liquid separation process.

[0045] Please refer to Figures 5-8 , as part of the viscous impurities is easy to adhere to the inner wall of the conical filter cartridge 21 and gradually form a filter cake layer during the rotation and filtration process, affecting the flux and filtration effect, therefore, the conical filter cartridge 21 is composed of a plurality of arc-shaped filter plates 211 which are evenly distributed in the circumferential direction and are hinged, and an elastic sealing strip is arranged between the adjacent arc-shaped filter plates 211, which not only ensures the stability of the structure of the conical filter cartridge 21 during rotation, but also effectively prevents the unfiltered wastewater from leaking between the plate joints, and the large-diameter end of each arc-shaped filter plate 211 is used as a rotating section 212, and the small-diameter end is used as a fixed section, when the arc-shaped filter plate 211 rotates to the upper region of the filter bin 2, the rotating section 212 can be turned outward by 180° relative to the fixed section, so that the filter surface originally facing the inside and adhering the filter cake is turned to the outside, thereby exposing the position which can be scraped, and providing a basis for subsequent efficient removal of the filter cake.

[0046] It should be noted that the filtered clean water can only be discharged through the water outlet 23 located at the bottom of the filter bin 2, and the water outlet 23 is opposite to the region where the rotating section 212 is located, so that the solid pollutants in the wastewater are mainly concentrated and intercepted on the surface of the rotating section 212, and the fixed section is in a non-main flow channel and continuously rotates, so that the water flow is disturbed, and it is not easy to form a stable filter cake, and basically no pollutants are attached, so as to realize the directional enrichment and efficient removal of the filter cake.

[0047] And, a scraper 24 is arranged on the top of the filter bin 2, which can move along the generatrix direction of the rotating section 212 of the arc-shaped filter plate 211, and when the arc-shaped filter plate 211 rotates to the top position and its rotating section 212 completes 180° flip to make the filter surface outward, the scraper 24 can immediately scrape the exposed filter cake layer, effectively prevent the blockage caused by the accumulation of impurities, and guide the scraped solid pollutants out of the filter bin 2 through the pollution outlet, ensuring the continuous cleaning of the filter surface.

[0048] Please refer to Figures 6-8 In order to realize the automatic flip action of the rotating section 212 of the arc-shaped filter plate 211, a rotating column is arranged on the side of the rotating section 212 of the arc-shaped filter plate 211 close to the fixed section, and a connecting gear 213 is arranged on the end of the rotating column close to the fixed section. The rotating column and the connecting gear 213 are in rotating cooperation with the fixed section, and a connecting ring 214 in sliding cooperation with the connecting gear 213 in the circumferential direction is fixedly arranged on the inner wall of the filter bin 2. The upper region of the connecting ring 214 is provided with a meshing tooth section 215 for precise meshing with the connecting gear 213 at a specific position.

[0049] When the conical filter drum 21 rotates, each arc-shaped filter plate 211 rotates synchronously, and when any arc-shaped filter plate 211 runs to the top region of the filter bin 2, its connecting gear 213 just enters the range of the meshing tooth section 215, and after the two are meshed, the rotating column is driven to rotate, thereby driving the rotating section 212 to flip 180° outward relative to the fixed section, so that the filter surface with the filter cake faces outward. In the non-top region, the connecting gear 213 is disengaged from the meshing tooth section 215, and the rotating section 212 remains in the original state to maintain normal filtration.

[0050] In addition, please refer to Figures 6-8 A guide ring 217 in sliding cooperation with each arc-shaped filter plate 211 is arranged on the inner wall of the filter bin 2, and two symmetrically arranged protrusions 218 are arranged on the lower part of the guide ring 217. The protrusions 218 are in sliding cooperation with the arc-shaped filter plate 211, and when the arc-shaped filter plate 211 rotates with the conical filter drum 21 to the position corresponding to the protrusions 218, under the pushing action of the protrusions 218, the arc-shaped filter plate 211 can produce a small outward flip or swing around the hinge, which is not enough to damage the sealing performance of the elastic sealing strip between adjacent arc-shaped filter plates 211, but can disturb the boundary layer of the wastewater flowing through the filter surface, break the local concentration polarization, and enhance the migration and interception of particulate matter to the filter surface, thereby improving the dynamic filtration efficiency.

[0051] Please refer to Figures 9-11To realize the scraping action of the scraper 24, an inclined rod 219 is installed on the side of the scraper 24 away from the arc-shaped filter plate 211 and is in sliding fit with the water inlet pipe 12. The inclined rod 219 realizes dynamic sealing with the water inlet pipe 12 through a sealing gasket sleeved on the outer periphery of the inclined rod 219. The sealing gasket can maintain effective sealing when the inclined rod 219 slightly swings or tilts with the scraping action, preventing waste water leakage. The other end of the inclined rod 219 is hinged to a moving plate 220, which is slidingly installed on a vertical column 221. The vertical column 221 is fixedly installed inside the filter bin 2. When the moving plate 220 slides up and down along the vertical column 221, it drives the inclined rod 219 to move synchronously, thereby driving the scraper 24 to tilt and move, so that it is tightly attached to the surface of the rotating section 212 of the arc-shaped filter plate 211 turned to the outside, efficiently scraping the attached dirt, and realizing automatic slag removal.

[0052] Meanwhile, please refer to Figures 3-5 , Figure 9 and Figure 10 , a sewage outlet is formed on the top of the filter bin 2 corresponding to the position of the scraper 24. An extension plate 131 is installed outside the filter bin 2 corresponding to the position of the sewage outlet. A storage frame 132 is arranged below the extension plate 131 for receiving the scraped dirt. A bracket is installed outside the filter bin 2 for placing the storage frame 132. The filter cake and impurities scraped by the scraper 24 are discharged through the sewage outlet, slide down along the extension plate 131 and fall into the storage frame 132, realizing centralized collection and convenient cleaning of the dirt.

[0053] In addition, please refer to Figure 10 and Figure 11 , a connecting spring 222 is connected between the moving plate 220 and the upper end of the vertical column 221 and is sleeved on the outer side of the vertical column 221. The connecting spring 222 is used to support the moving plate 220 and the vertical column 221 and to provide elastic support upwardly to the moving plate 220. When the connecting spring 222 is in a natural elongation state, the moving plate 220 drives the inclined rod 219 and the scraper 24 to remain in a ready position close to the rotating section 212 of the arc-shaped filter plate 211. At this time, the scraper 24 leaves a gap with the surface of the rotating section 212, which does not affect the turning action. A pushing plate 223 is arranged below the moving plate 220 and is in sliding fit with the vertical column 221. An inclined groove plate 224 is installed on the side of the moving plate 220 close to the pushing plate 223. A pull rod 225 is hinged to the upper end of the pushing plate 223 and is in sliding fit with the inclined groove plate 224. One side of the pushing plate 223 is connected to the extension end of an electric push rod 226. The electric push rod 226 is of a multi-stage sleeve type structure and is integrally packaged in a sealed housing. The sealed housing is fixedly installed on the inner wall of the water inlet pipe 12. Only the extension end of the electric push rod 226 penetrates through a dynamic sealing assembly on the sealed housing to extend outward, effectively preventing the cleaning waste water in the water inlet pipe 12 from seeping into the internal transmission mechanism, ensuring long-term stable operation of the electric push rod 226 in a wet working condition, and ensuring that the extension action is not affected by the liquid environment.

[0054] In the initial state, the electric push rod 226 is in the full extension state; during the scraping operation, the electric push rod 226 is retracted, pulling the push plate 223 to move downward along the stand 221, the push plate 223 drives the inclined groove plate 224 to swing downward through the pull rod 225, and then the inclined rod 219 and the scraper 24 are synchronously inclined downward, so that the scraper 24 closely contacts the surface of the rotating section 212 of the arc-shaped filter plate 211 which has been turned to the outside, and the attached dirt is efficiently scraped off; during the resetting, the electric push rod 226 is re-elongated, the push plate 223 is moved upward, the inclined groove plate 224 and the inclined rod 219 are inclined upward through the pull rod 225, so that the scraper 24 is in an upward inclined posture, avoiding that the scraped dirt is brought back to the surface of the filter plate during the return process.

[0055] It should be noted that the cleaning waste water in the filter bin 2 and the conical filter cartridge 21 is not in a full liquid state during operation, and is usually maintained below half of the volume of the bin, so as to reserve sufficient gas phase space, which is beneficial to the formation of effective disturbance of the waste water during the rotating filtration process, promotes the settlement and interception of particulate matters, and ensures that the liquid surface is far below the position of the dirt discharge port when the scraper 24 scrapes off the dirt and discharges the dirt through the top dirt discharge port, so as to avoid that the waste water is overflowed with the dirt, and to ensure the sealing property and operation reliability of the dirt discharge process.

[0056] Please refer to Figures 3-5 In order to realize the rotation of the conical filter cartridge 21, a rotating ring 26 which is rotationally connected with the filter bin 2 is arranged at the small-diameter end of the conical filter cartridge 21, a rotating pulley 261 is fixedly sleeved on the outer side of the rotating ring 26, a transmission pulley 262 is arranged at the rear side of the rotating pulley 261, the rotating pulley 261 and the transmission pulley 262 are transmissionally connected through a belt 263, the transmission pulleys 262 on the left and right sides are connected with a connecting shaft 264, the connecting shaft 264 is rotationally supported on the side frame which is fixedly connected with the filter bin 2, the transmission pulley 262 on the left side is connected with the output shaft of a driving motor 265, and the driving motor 265 is installed on the outer side of the filter bin 2 through a support.

[0057] During operation, the driving motor 265 drives the transmission pulley 262 on the left side to rotate, the transmission pulley 262 on the right side is synchronously rotated through the connecting shaft 264, and the transmission pulleys 262 on the left and right sides respectively drive the corresponding rotating pulleys 261 through the belt 263, so as to realize the synchronous and same-direction rotation of the two conical filter cartridges 21, and to ensure the stable and coordinated filtration process.

The outer side of the cam 282 is provided with a matching groove, and the matching groove is slidably installed with a moving rod 283 slidably matched with the flow distribution conical block 22 and the filter bin 2. When the conical filter cartridge 21 rotates, the horizontal rod 281 and the cam 282 are driven to rotate synchronously by the annular frame 279. The cam 282 drives the moving rod 283 to reciprocate in the vertical direction through the change of the profile of the matching groove in the rotating process, so as to convert the rotating motion of the conical filter cartridge 21 into the periodic lifting of the moving rod 283.

[0064] Please refer to Figure 12 and Figure 13 In order to realize the reciprocating rotation of the rotating shaft 277, a control column 284 is rotatably installed at the lower end of the moving rod 283.

When the moving rod 283 reciprocates in the vertical direction under the drive of the cam 282, the control column 284 is driven to move up and down synchronously. In this process, the protrusion 287 is embedded in the spiral groove 286 and slides relatively, so as to force the control column 284 to rotate reciprocally around its own axis while lifting and lowering. The extension rod 288 is stretched and contracted correspondingly with the rotation and displacement of the control column 284, and transmits the motion to the rotating shaft 277, so as to drive the rotating shaft 277, the arc-shaped groove plate 274 and the stirring blades 278 to realize reciprocating rotation synchronously.

[0065] In specific use (working time), the cleaning wastewater is collected by the collecting pipeline 11 into the filtering bin 2, and is evenly distributed into the filtering space of the left and right two conical filter cylinders 21 through the shunt conical block 22. After the driving motor 265 is started, the two conical filter cylinders 21 are synchronously rotated by the driving of the transmission pulley 262, the connecting shaft 264 and the belt 263, so as to realize the dynamic filtration of the wastewater. In the rotating process, when the arc-shaped filter plate 211, which has completed the filtration, runs to the upper region, the connecting gear 213 on the rotating section 212 is engaged with the meshing gear section 215 on the connecting ring 214 fixed to the inner wall of the filtering bin 2, so as to drive the rotating column to drive the rotating section 212 to turn over 180° outward, so that the filter surface with the filter cake is outwardly turned. Then, the electric push rod 226 is retracted, the push plate 223 is pulled downward, the scraper 24 is tightly attached to the turned filter surface through the linkage of the pull rod 225, the inclined slot plate 224, the inclined rod 219 and the moving plate 220, the dirt is scraped off and discharged through the top dirt outlet, and then falls along the extension plate 131 into the external storage frame 132 to complete the unified collection. At the same time, the conical filter cylinder 21 is linked with the horizontal rod 281 through the annular frame 279, the driving cam 282 is synchronously rotated, the moving rod 283 is reciprocatingly moved along the vertical direction, the moving rod 283 drives the control column 284 to be lifted and lowered, the control column 284 is reciprocatingly rotated under the cooperation of the spiral groove 286 and the inner protrusion 287 of the fixed sleeve ring 285, the arc-shaped slot plate 274 and the upper and lower stirring blades 278 are cooperatively operated through the driving of the rotating shaft 277 by the telescopic rod 288, so that the turbulence plate 272 is moved in the radial direction and rotated, and the filtered wastewater and the neutralizing agent are efficiently mixed.
