Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically a medical wastewater treatment device. Background Technology

[0002] With the rapid development of the medical and health industry and increasingly stringent environmental standards, the safe and efficient treatment of medical wastewater has become a focus of widespread social concern. Medical wastewater contains large amounts of cotton fibers, gauze fragments, soft debris, tiny pathogens, and large organic molecules. Direct discharge without deep purification and thorough disinfection poses a serious threat to the ecological environment and public health. In recent years, wastewater treatment technology has been gradually developing towards high automation, integration, and multi-stage combined treatment. Integrated medical wastewater treatment equipment, capable of pre-crushing, multi-stage fine filtration, high-efficiency sterilization, and automated solid waste collection, can effectively cut off pathogen transmission routes and prevent secondary pollution. It has extremely broad market prospects and application demand in the current and future fields of environmental protection equipment manufacturing and medical logistics support.

[0003] Currently, common medical wastewater treatment systems typically employ a basic process combining gravity sedimentation, traditional bar screens, and chemical disinfection. Some more advanced treatment equipment incorporates conventional membrane filtration technology driven by independent motors or pumps to improve water quality. Regarding solid-liquid separation and waste removal, existing coarse and fine filtration devices mostly utilize simple external mechanical scrapers for surface removal.

[0004] However, the aforementioned existing technologies have revealed many obvious shortcomings in practical applications: First, in the coarse filtration stage, the existing slag discharge methods are mostly open or simple gravity sliding, lacking an automatic sealing isolation and precise opening and closing mechanism for bottom slag discharge, which makes it easy for the intercepted coarse slag to accumulate and clog in the discharge pipeline; Second, in the fine filtration stage, tiny suspended solids and flocculent matter easily clog the filter mesh, causing the equipment flow rate to drop rapidly and requiring frequent manual disassembly and cleaning; Finally, the traditional ultraviolet lamp sterilization in the terminal ultrafiltration stage has obvious light source dead zones. Therefore, those skilled in the art provide a medical wastewater treatment device to solve the problems mentioned in the background. Summary of the Invention

[0005] The purpose of this invention is to provide a medical wastewater treatment device to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The wastewater treatment device includes a crushing mechanism, a coarse filtration mechanism, a fine filtration mechanism, an ultrafiltration mechanism, a temperature control mechanism, and a recovery tank. The crushing mechanism is connected to the coarse filtration mechanism, the coarse filtration mechanism is connected to the fine filtration mechanism, the fine filtration mechanism is connected to the ultrafiltration mechanism, the coarse filtration mechanism and the fine filtration mechanism are both connected to the recovery tank, the temperature control mechanism and the ultrafiltration mechanism are tightly connected, and the temperature control mechanism and the recovery tank are tightly connected.

[0007] By adopting the above technical solution, wastewater undergoes graded treatment through a crushing mechanism, a coarse filtration mechanism, a fine filtration mechanism, and an ultrafiltration mechanism. The crushing mechanism first breaks down cotton fibers, gauze fragments, soft debris, and larger particles mixed in the medical wastewater, making it less prone to clogging in subsequent filtration processes. The coarse filtration mechanism initially intercepts larger solid impurities after crushing. The fine filtration mechanism further screens smaller particles and flocculent matter. The ultrafiltration mechanism performs deep filtration on the wastewater after fine filtration to improve the cleanliness of the effluent. Impurities intercepted by the coarse and fine filtration mechanisms can be collected in recycling tanks for centralized collection, facilitating subsequent unified cleaning. The temperature control mechanism is securely connected to the ultrafiltration mechanism and the recycling tank, enabling temperature regulation during the ultrafiltration and impurity recovery stages of wastewater treatment. This reduces the impact of wastewater temperature fluctuations on ultrafiltration efficiency and the state of impurities in the recycling tank, thus forming a continuous treatment process with crushing, coarse filtration, fine filtration, ultrafiltration, temperature control, and recycling working in tandem, improving the stability, continuity, and ease of maintenance of medical wastewater treatment.

[0008] Furthermore, the pulverizing mechanism includes a pulverizing rod, a pulverizing motor, a pulverizing box, a water pump, and a water inlet pipe. The water inlet pipe is connected to the water pump, the water pump is connected to the pulverizing box, the pulverizing motor is fastened to the pulverizing box, the pulverizing motor is driven to the pulverizing rod, the pulverizing rod is rotatably connected to the pulverizing box, and the pulverizing box is connected to the coarse filtration mechanism.

[0009] By adopting the above technical solution, the inlet pipe is used to connect with the medical wastewater discharge end. The inlet pump stably delivers the wastewater to the pulverizing box through the inlet pipe, so that the wastewater enters the pulverizing area at a stable flow rate. The pulverizing motor is fixed on the pulverizing box and drives the pulverizing rod to rotate. When the pulverizing rod rotates relative to the pulverizing box, it cuts and crushes the gauze scraps, cotton lint, hose fragments and large particles of dirt that enter the pulverizing box. The pulverizing box provides installation and processing space for the pulverizing rod and guides the pulverized wastewater into the coarse filtration mechanism. This reduces the size of solid impurities before the wastewater enters the filtration structure, avoids large impurities directly impacting the filtration components, reduces the load on the coarse filtration mechanism, and improves the smoothness of subsequent coarse filtration, fine filtration and ultrafiltration processes.

[0010] Furthermore, the coarse filtration mechanism includes a coarse filter box, a coarse filter assembly, a discharge assembly, and a transmission assembly. The coarse filter box is connected to the pulverizing box, the coarse filter assembly is slidably connected to the coarse filter box, the discharge assembly is fastened to the coarse filter box, the discharge assembly is driven to the coarse filter assembly, the coarse filter assembly is driven to the transmission assembly, and the transmission assembly is driven to the fine filtration mechanism.

[0011] By adopting the above technical solution, after the pulverized wastewater enters the coarse filter box, the coarse filter assembly intercepts larger particles and incompletely pulverized solid impurities in the wastewater. The coarse filter assembly is slidably connected to the coarse filter box, allowing it to undergo relative displacement under the action of wastewater buoyancy, impurity accumulation, or discharge. The discharge assembly is fixed to the coarse filter box and is drivenly connected to the coarse filter assembly, used to control the discharge of intercepted impurities when the coarse filter assembly needs cleaning. The transmission assembly is drivenly connected to the coarse filter assembly and transmits the displacement action of the coarse filter assembly to the fine filtration mechanism, so that the state changes in the coarse filtration process can be linked to the subsequent fine filtration process. Through the cooperation of the coarse filter box, coarse filter assembly, discharge assembly, and transmission assembly, synchronous control of coarse filtration, impurity discharge, and subsequent linkage can be achieved, reducing the frequency of manual disassembly and cleaning and improving the continuity of equipment operation.

[0012] Furthermore, the coarse filter assembly includes a sliding box, a first opening and closing plate, a second opening and closing plate, a reset elastic element, a reset column, an elastic airbag, and an air pump. The sliding box and the coarse filter box are slidably connected, and the sliding box and the discharge assembly are fastened together. The first and second opening and closing plates are both rotatably connected to the reset column. The reset column and the sliding box are slidably connected, and the first and second opening and closing plates are hinged. The reset elastic element and the reset column are fastened together, and the reset elastic element and the sliding box are fastened together. The elastic airbag and the sliding box are fastened together, and the air pump and the coarse filter box are fastened together. The air pump and the elastic airbag are connected. The sliding box and the transmission assembly are connected. The sliding box is provided with coarse filter holes, a reset groove, and a pre-filter chamber. The reset groove is inverted T-shaped. The reset column and the reset groove are slidably connected. The coarse filter box is provided with a post-filter chamber. The coarse filter holes are connected to the pre-filter chamber, and the post-filter chamber is connected to the coarse filter holes.

[0013] By adopting the above technical solution, the sliding box, as the main body of the coarse filter assembly, slides within the coarse filter box to form a pre-filter chamber. Wastewater enters the pre-filter chamber and flows through the coarse filter holes to the post-filter chamber of the coarse filter box. Larger impurities are blocked in the pre-filter chamber. The first and second opening plates rotate around the reset column and are hinged to each other. During normal filtration, they can cooperate to close the discharge direction of the pre-filter chamber. When discharge is required, they can open to form a discharge channel. The reset column slides along the inverted T-shaped reset groove, which restricts the movement direction of the reset column and prevents it from detaching. The reset spring... The component connects the reset column and the sliding box, so that the first and second opening and closing plates automatically reset after discharge. The elastic airbag is fixed on the sliding box, and the air pump is fixed on the coarse filter box and connected to the elastic airbag. By inflating the elastic airbag, the sliding box can be pushed, causing the sliding box to slide in the coarse filter box as the wastewater level rises. The pre-filtration chamber, coarse filter holes, and post-filtration chamber are connected in sequence, so that the wastewater can complete the coarse filtration process of water entering from the pre-filtration chamber, filtration through the pores, and water exiting from the post-filtration chamber. This ensures the filtration throughput while achieving the controllable accumulation and discharge of coarse filter impurities.

[0014] Furthermore, the emission assembly includes a first electromagnetic block, a control elastic element, a first magnetic block, a sliding column, a contact block, and an opening / closing hydraulic cylinder. The coarse filter box is provided with an emission chamber, which is connected to the recovery box. The magnetic poles of the first electromagnetic block and the first magnetic block are attracted and driven. The control elastic element and the first electromagnetic block are fastened together. The control elastic element and the first magnetic block are fastened together. The sliding column and the coarse filter box are slidably connected. The sliding column and the sliding box are fastened together. The opening / closing hydraulic cylinder and the coarse filter box are fastened together. The opening / closing hydraulic cylinder and the contact block are driven together. The first opening / closing plate and the second opening / closing plate both abut against the contact block.

[0015] By adopting the above technical solution, the first electromagnetic block and the first magnetic block form a controllable attraction effect through magnetic pole attraction. The control elastic element connects the first electromagnetic block and the first magnetic block. When the first electromagnetic block is energized and de-energized, it can cooperate with the magnetic attraction force to realize the position change and elastic reset of the first magnetic block. The sliding column is slidably connected to the coarse filter box and is fastened to the sliding box, so that the movement of the sliding box can drive the sliding column to move synchronously. The sliding column, together with the first magnetic block, the control elastic element and the first electromagnetic block, realizes the trigger control of the discharge action. The opening and closing hydraulic cylinder is fixed to the coarse filter box and drives the abutment block to move. The abutment block abuts against the first opening and closing plate and the second opening and closing plate. When the opening and closing hydraulic cylinder pushes the abutment block, the abutment block causes the first opening and closing plate and the second opening and closing plate to open. The impurities trapped in the pre-filter chamber enter the discharge chamber set in the coarse filter box and are discharged into the recovery box through the discharge chamber. Thus, the discharge assembly can realize the directional discharge of coarse filter impurities by using the cooperation of electromagnetic attraction, elastic reset, sliding transmission and hydraulic opening and closing, reducing filter hole blockage and improving the reliability of impurity collection in the recovery box.

[0016] Furthermore, the transmission assembly includes a transmission gear, a floating rack, and a transmission rack. The transmission gear is rotatably connected to the coarse filter box, the floating rack is fastened to the sliding box, the floating rack is slidably connected to the coarse filter box, the floating rack is rotatably connected to the transmission gear, the transmission gear and the transmission rack are drivenly connected, the transmission rack is slidably connected to the coarse filter box, and the transmission rack is drivenly connected to the fine filter mechanism.

[0017] By adopting the above technical solution, when the sliding box moves within the coarse filter box, it drives the floating rack to slide synchronously. The floating rack engages with the transmission gear, converting the linear displacement of the sliding box into the rotation of the transmission gear. The transmission gear then meshes with the transmission rack, driving the transmission rack to slide along the coarse filter box. The transmission rack is further connected to the fine filter mechanism, thereby transmitting the movement of the coarse filter component caused by filtration pressure, slag discharge action, or airbag adjustment to the fine filter mechanism. Through the mechanical transmission of the floating rack, transmission gear, and transmission rack, a linkage relationship can be formed between the coarse and fine filter mechanisms. As the water level of the pre-treated wastewater changes, the fine filter mechanism can synchronously adjust its operating state according to the coarse filtration status, reducing the complexity of separately setting up detection and control structures and improving the consistency of the overall transmission response.

[0018] Furthermore, the fine filtration mechanism includes a fine filtration component, a follower component, and a plate and frame filter press. The drive rack and follower component are connected by a drive mechanism, the follower component is connected by a drive mechanism to the fine filtration component, the fine filtration component is connected to the coarse filtration box, the fine filtration component is connected to the plate and frame filter press, and the plate and frame filter press is connected to the recovery box. The fine filtration assembly includes a fine filter box, a screw rod, a rotating box, a control pump, a rotating block, a fine screen water pipe, and an auxiliary motor. The fine filter box and the control pump are connected, and the control pump and the filtered chamber are connected. The follower assembly and the fine filter box are fastened together. The auxiliary motor and the fine filter box are fastened together. The auxiliary motor and the screw rod are driven together. The rotating box and the fine filter box are rotatably connected. The rotating block and the fine filter box are embedded and rotate. The fine screen water pipe and the rotating block are embedded and rotate. The follower assembly and the rotating block are driven together. The screw rod is located inside the rotating box. Both the screw rod and the rotating box are frustum-shaped. The rotating box is connected to the plate and frame filter press. The rotating box is provided with fine filtration holes.

[0019] By adopting the above technical solution, the wastewater in the filtration chamber enters the fine filter box under the action of the control pump. The fine filter box provides installation and filtration space for the fine filter components. An auxiliary motor drives the screw rod to rotate. The screw rod is located inside the rotating box and conveys, squeezes, and agitates the fine particles in the wastewater along the frustum-shaped structure. The rotating box rotates relative to the fine filter box, and the fine filter holes set on the rotating box perform fine filtration of the wastewater, so that fine particles, flocculent impurities, and some suspended solids are trapped in the rotating box. The filtered liquid enters the subsequent flow path. The rotating block is embedded in the fine filter box and can rotate. The fine screen water pipe is embedded in the rotating block and can rotate relative to the rotating block. The movement of the fine filtration mechanism causes the water pipe to change its inlet / outlet or rinsing direction under the drive of the follower component, improving the flow uniformity in the fine filtration area. The follower component is connected to the transmission rack and pinion and works with the fine filtration box and the rotating block, so that the movement of the coarse filtration mechanism can be linked with the fine filtration component. The sludge-like impurities and concentrate trapped in the rotating box are introduced into the plate and frame filter press for dewatering. The plate and frame filter press introduces the waste residue after filtration into the recovery box, while the concentrated liquid after filtration flows back into the fine filtration box. This achieves continuous coordination of fine filtration, guiding screening, screw conveying and filter press recovery, improving the removal efficiency of fine impurities and reducing the pollution load of the subsequent ultrafiltration mechanism.

[0020] Furthermore, the follower assembly includes a follower motor, bevel gears, planetary gears, auxiliary gears, planetary gear rings, follower elastic elements, follower electromagnetic blocks, and follower magnetic blocks. The transmission rack and follower motor are connected by a drive mechanism; the follower motor and fine filter box are slidably connected; the follower electromagnetic block and fine filter box are fastened together; the magnetic poles of the follower electromagnetic block and follower magnetic block are attracted to each other; the follower elastic element and follower electromagnetic block are fastened together; the follower elastic element and follower magnetic block are fastened together; the follower magnetic block and follower motor are fastened together; the follower motor and bevel gears are connected by a drive mechanism; the bevel gears and planetary gears are connected by a drive mechanism; the bevel gears and rotating box are connected by a drive mechanism; the planetary gear ring and planetary gears are connected by a drive mechanism; the planetary gears and auxiliary gears are connected by a drive mechanism; the planetary gears and fine screen water pipes are fastened together; the auxiliary gears and helical rods are fastened together; the rotating box has rotating teeth; the bevel gears and rotating teeth are slidably connected; and the helical rod and rotating box rotate in opposite directions.

[0021] By adopting the above technical solution, the transmission rack drives the follower motor to generate displacement. The follower motor slides on the fine filter box and drives the bevel gear to rotate. The follower electromagnetic block is fixed to the fine filter box, and the follower magnetic block is firmly connected to the follower motor. The follower electromagnetic block and the follower magnetic block control the position of the follower motor through magnetic pole attraction. The follower elastic element connects the follower electromagnetic block and the follower magnetic block, and is used to drive the follower motor to reset after power failure or unloading. When the follower motor is in the working position, the bevel gear slides and meshes with the rotating teeth on the rotating box, driving the rotating box to rotate. Simultaneously, the bevel gear drives the planetary gear, which meshes with the planetary gear ring and drives the fine screen water pipe to move. The planetary gear also drives the auxiliary gear, which drives the screw rod to rotate, so that the screw rod and the rotating box form a rotation direction opposite to each other. Through the cooperation of the bevel gear, planetary gear, auxiliary gear, planetary gear ring, rotating teeth, follower elastic element, follower electromagnetic block and follower magnetic block, the rotating box, screw rod and fine screen water pipe can form a compound motion, which enhances the shearing, turbulence and anti-clogging ability of wastewater in the fine filter box, and improves the continuous water flow performance of the fine filter pores.

[0022] Furthermore, the ultrafiltration mechanism includes an ultrafiltration membrane module, an ultrafiltration box, an optical fiber network, an air valve, a condenser plate, a water storage tank, and an outlet pipe. The ultrafiltration membrane module is connected to the fine filter box, the ultrafiltration membrane module is connected to the ultrafiltration box, the optical fiber network is securely connected to the ultrafiltration box, the air valve is connected to the ultrafiltration box, the air valve is connected to the water storage tank, the condenser plate is securely connected to the water storage tank, and the water storage tank is connected to the outlet pipe.

[0023] By adopting the above technical solution, the optical fiber mesh is fixed inside the ultrafiltration box and effectively kills microorganisms, bacteria, and viruses in the wastewater through ultraviolet disinfection. The optical fiber mesh guides the ultraviolet light source into the water inside the ultrafiltration box, playing a disinfection role during the filtration process and effectively reducing microbial contamination. Due to the mesh structure of the optical fiber mesh, ultraviolet light can be evenly distributed within the ultrafiltration box, further improving disinfection efficiency and providing a structural basis for water condition observation and light conduction processing, making the water distribution within the ultrafiltration box more uniform. In addition, the air valve is connected to the ultrafiltration box and the water storage tank to control the direction of gas-liquid flow discharge within the ultrafiltration box. The condenser plate condenses water vapor in the wastewater and collects it in the water storage tank, providing a condensation and temporary storage process for the water storage tank, ensuring that the wastewater can be further stabilized after ultraviolet disinfection and finally discharged through the effluent pipe. Thus, a comprehensive treatment effect of deep filtration, ultraviolet disinfection, flow guidance and pressure stabilization, condensation collection, and stable drainage of wastewater can be achieved, improving the end-of-pipe treatment effect of medical wastewater and ensuring that the treated wastewater meets safe discharge standards.

[0024] Furthermore, the temperature control mechanism includes a heating chamber, a cooling chamber, a circulating pump, and a circulating pipe. The heating chamber and the cooling chamber are connected, the circulating pump and the heating chamber are connected, the circulating pipe and the circulating pump are connected, and the circulating pipe and the cooling chamber are connected. The ultrafiltration chamber and the recovery chamber are both securely connected to the circulating pipe.

[0025] By adopting the above technical solution, the heating box and cooling box are connected to form a basic heat exchange medium for temperature regulation. The circulating pump is connected to the heating box and pressurizes the temperature regulation medium into the circulating pipe. The circulating pipe is then connected to the cooling box to form a circulation loop. Since the circulating pipe is tightly connected to the ultrafiltration box and the recovery box respectively, the temperature regulation medium in the circulating pipe can exchange heat between the ultrafiltration box and the recovery box, so that the ultrafiltration box is maintained within a suitable filtration temperature range. At the same time, the waste residue, concentrate or impurities collected in the recovery box are in a relatively stable temperature environment, reducing sedimentation and odor diffusion. Through the circulation and coordination of the heating box, cooling box, circulating pump and circulating pipe, heating, cooling and constant temperature control can be achieved according to the treatment needs, improving the operational stability of the ultrafiltration mechanism and the convenience of subsequent cleaning of the recovery box.

[0026] Compared with the prior art, the beneficial effects of the present invention are: An air pump adjusts the elastic airbag, pushing the sliding box to slide back and forth within the coarse filter box for filtration. During slag discharge, the first electromagnetic block is energized, attracting the first magnetic block and locking the sliding column position. Subsequently, the opening and closing hydraulic cylinder extends and pushes the abutment block, forcibly opening the hinged first and second opening and closing plates. The reset column of the opening and closing plate slides along the inverted T-shaped reset groove and compresses the reset elastic element, allowing the intercepted coarse slag to fall directly into the discharge chamber. After the force is released, the spring automatically resets and closes. This bottom-level connection and action design achieves automatic airtight isolation and precise fixed-point discharge of coarse slag, effectively preventing blockage of the discharge pipeline. The floating rack and transmission gear mechanically transmit the displacement of the sliding box to the fine filter component, realizing the linkage between coarse and fine filtration. After the follower motor starts, the bevel gear drives the perforated frustum-shaped rotating box to rotate, and simultaneously drives the internal fine screen water pipe and frustum-shaped spiral rod to rotate through a composite gear system composed of planetary gears and auxiliary gears. This composite transmission causes the screw and the rotating box to rotate at high speed in opposite directions. Under double centrifugation and extrusion, an extremely strong mechanical shearing force is formed on the surface of the fine filter pores. This not only forces tiny impurities into the plate and frame filter press, but also achieves efficient physical self-cleaning of the fine filter pores, preventing clogging. The ultrafiltration box is tightly connected with an optical fiber mesh, which evenly diffuses ultraviolet light into the entire water body. Combined with the gas-liquid phase change separation of the air valve and the condenser plate, this enables the discharge of qualified water after sterilization. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-12 As shown, the present invention provides a technical solution for a medical wastewater treatment device: The wastewater treatment device includes a crushing mechanism 1, a coarse filtration mechanism 2, a fine filtration mechanism 3, an ultrafiltration mechanism 4, a temperature control mechanism 5, and a recovery tank 6. The crushing mechanism 1 is connected to the coarse filtration mechanism 2, the coarse filtration mechanism 2 is connected to the fine filtration mechanism 3, the fine filtration mechanism 3 is connected to the ultrafiltration mechanism 4, the coarse filtration mechanism 2 and the fine filtration mechanism 3 are both connected to the recovery tank 6, the temperature control mechanism 5 is tightly connected to the ultrafiltration mechanism 4, and the temperature control mechanism 5 is tightly connected to the recovery tank 6.

[0031] By adopting the above technical solution, the wastewater is sequentially treated through a crushing mechanism 1, a coarse filtration mechanism 2, a fine filtration mechanism 3, and an ultrafiltration mechanism 4. The crushing mechanism 1 first crushes the cotton lint, gauze fragments, soft debris, and larger particles mixed in the medical wastewater, making it less likely to clog in the subsequent filtration process. The coarse filtration mechanism 2 initially intercepts the larger solid impurities after crushing. The fine filtration mechanism 3 further screens the smaller particles and flocculent matter. The ultrafiltration mechanism 4 performs deep filtration on the finely filtered wastewater to improve the cleanliness of the effluent. The impurities intercepted by the coarse filtration mechanism 2 and the fine filtration mechanism 3 can be respectively introduced into the recovery tank 6 for centralized collection, facilitating subsequent unified cleaning. The temperature control mechanism 5 is tightly connected to the ultrafiltration mechanism 4 and the recovery tank 6, respectively, and can adjust the temperature during the ultrafiltration stage and the impurity recovery stage during the wastewater treatment process, reducing the impact of wastewater temperature fluctuations on the ultrafiltration efficiency and the state of impurities in the recovery tank 6. This forms a continuous treatment process with crushing, coarse filtration, fine filtration, ultrafiltration, temperature control, and recovery working together, improving the stability, continuity, and ease of maintenance of medical wastewater treatment.

[0032] Furthermore, the pulverizing mechanism 1 includes a pulverizing rod 11, a pulverizing motor 12, a pulverizing box 13, a water pump 14, and a water inlet pipe 15. The water inlet pipe 15 is connected to the water pump 14, the water pump 14 is connected to the pulverizing box 13, the pulverizing motor 12 is fastened to the pulverizing box 13, the pulverizing motor 12 is driven to the pulverizing rod 11, the pulverizing rod 11 is rotatably connected to the pulverizing box 13, and the pulverizing box 13 is connected to the coarse filtration mechanism 2.

[0033] By adopting the above technical solution, the inlet pipe 15 is used to connect with the medical wastewater discharge end. The inlet pump 14 stably transports the wastewater to the pulverizing box 13 through the inlet pipe 15, so that the wastewater enters the pulverizing area at a stable flow rate. The pulverizing motor 12 is fixed on the pulverizing box 13 and drives the pulverizing rod 11 to rotate. When the pulverizing rod 11 rotates relative to the pulverizing box 13, it cuts and crushes the gauze scraps, cotton lint, hose fragments and large particles of dirt that enter the pulverizing box 13. The pulverizing box 13 provides installation and processing space for the pulverizing rod 11 and introduces the pulverized wastewater into the coarse filtration mechanism 2. In this way, the size of solid impurities can be reduced before the wastewater enters the filtration structure, avoiding large impurities from directly impacting the filtration components, reducing the load on the coarse filtration mechanism 2, and improving the smoothness of the subsequent coarse filtration, fine filtration and ultrafiltration processes.

[0034] Furthermore, the coarse filtration mechanism 2 includes a coarse filter box 21, a coarse filter assembly 22, an discharge assembly 23, and a transmission assembly 24. The coarse filter box 21 is connected to the crushing box 13, the coarse filter assembly 22 is slidably connected to the coarse filter box 21, the discharge assembly 23 is fastened to the coarse filter box 21, the discharge assembly 23 is driven to the coarse filter assembly 22, the coarse filter assembly 22 is driven to the transmission assembly 24, and the transmission assembly 24 is driven to the fine filtration mechanism 3.

[0035] By adopting the above technical solution, after the pulverized wastewater enters the coarse filter box 21, the coarse filter assembly 22 intercepts larger particles and incompletely pulverized solid impurities in the wastewater. The coarse filter assembly 22 is slidably connected to the coarse filter box 21, allowing it to undergo relative displacement under the action of wastewater buoyancy, impurity accumulation, or discharge. The discharge assembly 23 is fixed to the coarse filter box 21 and is drivenly connected to the coarse filter assembly 22, used to control the discharge of intercepted impurities when the coarse filter assembly 22 needs cleaning. The transmission assembly 24 is drivenly connected to the coarse filter assembly 22 and transmits the displacement action of the coarse filter assembly 22 to the fine filter mechanism 3, so that the state changes in the coarse filtration process can be linked to the subsequent fine filtration process. Through the cooperation of the coarse filter box 21, the coarse filter assembly 22, the discharge assembly 23, and the transmission assembly 24, synchronous control of coarse filtration, impurity discharge, and subsequent linkage can be achieved, reducing the frequency of manual disassembly and cleaning and improving the continuity of device operation.

[0036] Furthermore, the coarse filter assembly 22 includes a sliding box 221, a first opening and closing plate 222, a second opening and closing plate 223, a reset elastic element 224, a reset column 225, an elastic airbag 226, and an air pump 227. The sliding box 221 and the coarse filter box 21 are slidably connected, and the sliding box 221 and the discharge assembly 23 are fastened together. The first opening and closing plate 222 and the second opening and closing plate 223 are both rotatably connected to the reset column 225. The reset column 225 and the sliding box 221 are slidably connected. The first opening and closing plate 222 and the second opening and closing plate 223 are hinged together. The reset elastic element 224 and the reset column 225 are fastened together.

The moving box 221 is fastened, the elastic airbag 226 and the sliding box 221 are fastened, the air pump 227 and the coarse filter box 21 are fastened, the air pump 227 and the elastic airbag 226 are connected, the sliding box 221 and the transmission assembly 24 are connected, the sliding box 221 is provided with a coarse filter hole 2211, a reset groove 2212 and a pre-filter chamber 2213, the reset groove 2212 is an inverted T-shape, the reset column 225 and the reset groove 2212 are slidably connected, the coarse filter box 21 is provided with a post-filter chamber 211, the coarse filter hole 2211 and the pre-filter chamber 2213 are connected, and the post-filter chamber 211 and the coarse filter hole 2211 are connected.

[0037] By adopting the above technical solution, the sliding box 221 serves as the main body of the coarse filter assembly 22. It slides within the coarse filter box 21 and forms a pre-filter chamber 2213. After wastewater enters the pre-filter chamber 2213, it flows through the coarse filter holes 2211 to the post-filter chamber 211 of the coarse filter box 21. Larger impurities are blocked within the pre-filter chamber 2213. The first opening plate 222 and the second opening plate 223 rotate around the reset column 225 and are hinged to each other. During normal filtration, they can cooperate to close the discharge direction of the pre-filter chamber 2213. When discharge is required, they can open to form a discharge channel. The reset column 225 slides along the inverted T-shaped reset groove 2212. The inverted T-shaped reset groove 2212 can restrict the movement direction of the reset column 225 and prevent it from detaching. The elastic element 224 connects the reset column 225 and the sliding box 221, so that the first opening and closing plate 222 and the second opening and closing plate 223 automatically reset after the discharge is completed. The elastic air bag 226 is fixed on the sliding box 221, and the air pump 227 is fixed on the coarse filter box 21 and communicates with the elastic air bag 226. By inflating the elastic air bag 226, the sliding box 221 can be pushed, so that the sliding box 221 slides in the coarse filter box 21 due to the rise of the wastewater level. The pre-filtration chamber 2213, the coarse filter hole 2211 and the post-filtration chamber 211 are connected in sequence, so that the wastewater can complete the coarse filtration process of water entering from the pre-filtration chamber, filtration through the pores and water exiting from the post-filtration chamber, thereby achieving the controllable accumulation and discharge of coarse filter impurities while ensuring the filtration flux.

[0038] Furthermore, the emission assembly 23 includes a first electromagnetic block 231, a control elastic element 232, a first magnetic block 233, a sliding column 234, an abutment block 235, and an opening and closing hydraulic cylinder 236. The coarse filter box 21 is provided with an emission chamber 212, which is connected to the recovery box 6. The magnetic poles of the first electromagnetic block 231 and the first magnetic block 233 are attracted and driven by each other. The control elastic element 232 is fastened to the first electromagnetic block 231, and the control elastic element 232 is fastened to the first magnetic block 233. The sliding column 234 is slidably connected to the coarse filter box 21, and the sliding column 234 is fastened to the sliding box 221. The opening and closing hydraulic cylinder 236 is fastened to the coarse filter box 21, and the opening and closing hydraulic cylinder 236 is driven to the abutment block 235. The first opening and closing plate 222 and the second opening and closing plate 223 both abut against the abutment block 235.

[0039] By adopting the above technical solution, the first electromagnetic block 231 and the first magnetic block 233 form a controllable attraction effect through magnetic pole attraction. The control elastic element 232 connects the first electromagnetic block 231 and the first magnetic block 233. When the first electromagnetic block 231 is energized and de-energized, it can cooperate with the magnetic attraction force to realize the position change and elastic reset of the first magnetic block 233. The sliding column 234 is slidably connected to the coarse filter box 21 and is fastened to the sliding box 221, so that the movement of the sliding box 221 can drive the sliding column 234 to move synchronously. The sliding column 234, together with the first magnetic block 233, the control elastic element 232 and the first electromagnetic block 231, realizes the trigger control of the discharge action and the opening and closing hydraulic system. Cylinder 236 is fixed to coarse filter box 21 and drives abutment block 235 to move. Abutment block 235 abuts against first opening and closing plate 222 and second opening and closing plate 223. When opening and closing hydraulic cylinder 236 pushes abutment block 235, abutment block 235 causes first opening and closing plate 222 and second opening and closing plate 223 to open. Impurities trapped in pre-filter chamber 2213 enter discharge chamber 212 provided in coarse filter box 21 and are discharged into recovery box 6 through discharge chamber 212. Thus, discharge assembly 23 can realize directional discharge of coarse filter impurities by using electromagnetic attraction, elastic reset, sliding transmission and hydraulic opening and closing, reducing filter hole blockage and improving the reliability of impurity collection in recovery box 6.

[0040] Furthermore, the transmission assembly 24 includes a transmission gear 241, a floating rack 242, and a transmission rack 243. The transmission gear 241 is rotatably connected to the coarse filter box 21, the floating rack 242 is fastened to the sliding box 221, the floating rack 242 is slidably connected to the coarse filter box 21, the floating rack 242 is rotatably connected to the transmission gear 241, the transmission gear 241 and the transmission rack 243 are drive-connected, the transmission rack 243 is slidably connected to the coarse filter box 21, and the transmission rack 243 is drive-connected to the fine filter mechanism 3.

[0041] By adopting the above technical solution, when the sliding box 221 moves within the coarse filter box 21, it drives the floating rack 242 to slide synchronously. The floating rack 242 engages with the transmission gear 241, converting the linear displacement of the sliding box 221 into the rotation of the transmission gear 241. The transmission gear 241 then meshes with the transmission rack 243, driving the transmission rack 243 to slide along the coarse filter box 21. The transmission rack 243 is further connected to the fine filter mechanism 3, thereby transmitting the movement of the coarse filter assembly 22 caused by filtration pressure, slag discharge action, or airbag adjustment to the fine filter mechanism 3. Through the mechanical transmission of the floating rack 242, the transmission gear 241, and the transmission rack 243, a linkage relationship can be formed between the coarse filter mechanism 2 and the fine filter mechanism 3. When the water level of the pre-treated wastewater changes, the fine filter mechanism 3 can synchronously adjust its operating state according to the coarse filtration state, reducing the complexity of setting up separate detection and control structures and improving the consistency of the overall transmission response.

[0042] Furthermore, the fine filtration mechanism 3 includes a fine filtration component 31, a follower component 32, and a plate and frame filter press 33. The transmission rack 243 is connected to the follower component 32, the follower component 32 is connected to the fine filtration component 31, the fine filtration component 31 is connected to the coarse filtration box 21, the fine filtration component 31 is connected to the plate and frame filter press 33, and the plate and frame filter press 33 is connected to the recovery box 6. The fine filtration assembly 31 includes a fine filtration box 311, a screw rod 312, a rotating box 313, a control pump 314, a rotating block 315, a fine screen water pipe 316, and an auxiliary motor 317.

Rotating box 313 is connected to plate and frame filter press 33. Fine filter hole 3131 is provided on rotating box 313.

[0043] By adopting the above technical solution, the wastewater in the filtration chamber 211 enters the fine filter box 311 under the action of the control pump 314. The fine filter box 311 provides installation and filtration space for the fine filter assembly 31. The auxiliary motor 317 drives the screw rod 312 to rotate. The screw rod 312 is located in the rotating box 313 and conveys, squeezes and agitates the fine particles in the wastewater along the frustum-shaped structure. The rotating box 313 rotates relative to the fine filter box 311, and the fine filter holes 3131 provided on the rotating box 313 perform fine filtration on the wastewater, so that fine particles, flocculent impurities and some suspended solids are trapped in the rotating box 313. The filtered liquid enters the subsequent flow path. The rotating block 315 is embedded in the fine filter box 311 and can rotate. The fine screen water pipe 316 is embedded in the rotating block 311. 5. It can rotate relative to the rotating block 315, so that the fine screen water pipe 316 changes the direction of water inlet / outlet or rinsing under the drive of the follower component 32, thereby improving the flow uniformity of the fine filtration area. The follower component 32 is connected to the transmission rack 243 and cooperates with the fine filter box 311 and the rotating block 315, so that the action of the coarse filtration mechanism 2 can be linked with the fine filtration component 31. The sludge-like impurities and concentrates intercepted by the rotating box 313 are introduced into the plate and frame filter press 33 for pressure filtration and dewatering. The plate and frame filter press 33 introduces the waste residue after pressure filtration into the recovery box 6, while the concentrated liquid after pressure filtration flows back into the fine filter box 311, thereby realizing the continuous coordination of fine filtration, guiding screening, screw conveying and pressure filtration recovery, improving the removal efficiency of fine impurities and reducing the pollution load of the subsequent ultrafiltration mechanism 4.

[0044] Furthermore, the follower assembly 32 includes a follower motor 321, a bevel gear 322, a planetary gear 323, an auxiliary gear 324, a planetary gear ring 325, a follower elastic element 326, a follower electromagnetic block 327, and a follower magnetic block 328. The transmission rack 243 is connected to the follower motor 321. The follower motor 321 is slidably connected to the fine filter box 311. The follower electromagnetic block 327 is fastened to the fine filter box 311. The magnetic poles of the follower electromagnetic block 327 and the follower magnetic block 328 attract each other for transmission. The follower elastic element 326 is fastened to the follower electromagnetic block 327. The follower elastic element 326 is fastened to the follower magnetic block 328. The locating block 328 is fastened to the follower motor 321. The follower motor 321 is driven by the bevel gear 322. The bevel gear 322 is driven by the planetary gear 323. The bevel gear 322 is driven by the rotating box 313. The planetary gear ring 325 is driven by the planetary gear 323. The planetary gear 323 is driven by the auxiliary gear 324. The planetary gear 323 is fastened to the fine screen water pipe 316. The auxiliary gear 324 is fastened to the spiral rod 312. The rotating box 313 is provided with rotating teeth 3132. The bevel gear 322 and the rotating teeth 3132 are slidably connected. The spiral rod 312 and the rotating box 313 rotate in opposite directions.

[0045] By adopting the above technical solution, the transmission rack 243 drives the follower motor 321 to generate displacement. The follower motor 321 slides on the fine filter box 311 and drives the bevel gear 322 to rotate. The follower electromagnetic block 327 is fixed to the fine filter box 311, and the follower magnetic block 328 is fastened to the follower motor 321. The follower electromagnetic block 327 and the follower magnetic block 328 control the position of the follower motor 321 through magnetic pole attraction. The follower elastic element 326 connects the follower electromagnetic block 327 and the follower magnetic block 328 and is used to drive the follower motor 321 to reset after power failure or unloading. When the follower motor 321 is in the working position, the bevel gear 322 slides and meshes with the rotating teeth 3132 on the rotating box 313 and drives the rotating box 313 to rotate. At the same time, the bevel gear 322 drives planetary gear 323, which meshes with planetary gear ring 325 and drives the fine screen water pipe 316 to move. Planetary gear 323 also drives auxiliary gear 324, which drives the screw rod 312 to rotate, so that the screw rod 312 and the rotating box 313 form opposite rotation directions. Through the cooperation of bevel gear 322, planetary gear 323, auxiliary gear 324, planetary gear ring 325, rotating teeth 3132, follower elastic element 326, follower electromagnetic block 327 and follower magnetic block 328, the rotating box 313, screw rod 312 and fine screen water pipe 316 can form a compound motion, which enhances the shearing, turbulence and anti-clogging ability of wastewater in the fine filter box 311, and improves the continuous water flow performance of the fine filter hole 3131.

[0046] Furthermore, the ultrafiltration mechanism 4 includes an ultrafiltration membrane module 41, an ultrafiltration box 42, an optical fiber network 43, an air valve 44, a condenser plate 45, a water storage tank 46, and an outlet pipe 47. The ultrafiltration membrane module 41 is connected to the fine filter box 311, the ultrafiltration membrane module 41 is connected to the ultrafiltration box 42, the optical fiber network 43 is securely connected to the ultrafiltration box 42, the air valve 44 is connected to the ultrafiltration box 42, the air valve 44 is connected to the water storage tank 46, the condenser plate 45 is securely connected to the water storage tank 46, and the water storage tank 46 is connected to the outlet pipe 47.

[0047] By adopting the above technical solution, the optical fiber mesh 43 is fixed inside the ultrafiltration box 42, and effectively kills microorganisms, bacteria, and viruses in the wastewater through ultraviolet disinfection. The optical fiber mesh 43 guides the ultraviolet light source into the water inside the ultrafiltration box 42, playing a disinfection role during the filtration process and effectively reducing microbial contamination. Due to the mesh structure of the fiber optic network 43, ultraviolet light can be evenly distributed within the ultrafiltration box 42, further improving disinfection efficiency and providing a structural basis for water condition observation and light transmission treatment, making the water distribution within the ultrafiltration box 42 more uniform. In addition, the air valve 44 is connected to the ultrafiltration box 42 and the water storage tank 46 to control the direction of gas-liquid flow discharge within the ultrafiltration box 42. The condenser plate 45 condenses water vapor in the wastewater and collects it into the water storage tank 46, providing a condensation and temporary storage process for the water storage tank 46, ensuring that the wastewater can be further stabilized after ultraviolet disinfection, and finally discharged through the outlet pipe 47. Thus, a comprehensive treatment effect of deep filtration, ultraviolet disinfection, flow guidance and pressure stabilization, condensation collection and stable drainage of wastewater can be achieved, improving the end-of-pipe treatment effect of medical wastewater and ensuring that the treated wastewater meets the safety discharge standards.

[0048] Furthermore, the temperature control mechanism 5 includes a heating box 51, a cooling box 52, a circulating pump 53, and a circulating pipe 54. The heating box 51 and the cooling box 52 are connected, the circulating pump 53 is connected to the heating box 51, the circulating pipe 54 is connected to the circulating pump 53, and the circulating pipe 54 is connected to the cooling box 52. The ultrafiltration box 42 and the recovery box 6 are both securely connected to the circulating pipe 54.

[0049] By adopting the above technical solution, the heating box 51 and the cooling box 52 are connected to form a heat exchange base for the temperature regulating medium. The circulating pump 53 is connected to the heating box 51 and pressurizes the temperature regulating medium into the circulating pipe 54. The circulating pipe 54 is then connected to the cooling box 52 to form a circulation loop. Since the circulating pipe 54 is tightly connected to the ultrafiltration box 42 and the recovery box 6 respectively, the temperature regulating medium in the circulating pipe 54 can exchange heat between the ultrafiltration box 42 and the recovery box 6, so that the ultrafiltration box 42 is maintained within a suitable filtration temperature range. At the same time, the waste residue, concentrate or impurities collected in the recovery box 6 are in a relatively stable temperature environment, reducing sedimentation and odor diffusion. Through the cyclical cooperation of the heating box 51, the cooling box 52, the circulating pump 53 and the circulating pipe 54, heating, cooling and constant temperature control can be achieved according to the processing needs, improving the operational stability of the ultrafiltration mechanism 4 and the convenience of subsequent cleaning of the recovery box 6.

[0050] Working principle of the invention: The air pump 227 adjusts the elastic airbag 226, pushing the sliding box 221 to slide back and forth within the coarse filter box 21 for filtration. During slag discharge, the first electromagnetic block 231 is energized to attract the first magnetic block 233 and lock the position of the sliding column 234. Subsequently, the opening and closing hydraulic cylinder 236 extends and pushes the abutment block 235, forcibly opening the hinged first opening and closing plate 222 and the second opening and closing plate 223. The reset column 225 of the opening and closing plate slides along the inverted T-shaped reset groove 2212 and compresses the reset elastic element 224, allowing the intercepted coarse slag to fall directly into the discharge chamber 212. After the force is released, the spring automatically resets and closes. The bottom connection and action design realizes the automatic sealing and precise discharge of coarse slag, effectively preventing the blockage of the discharge pipeline; the floating rack 242 and the transmission gear 241 mechanically transmit the displacement of the sliding box 221 to the fine filter component 31, realizing the linkage of coarse and fine filtration. After the follower motor 321 is started, the bevel gear 322 drives the perforated frustum-shaped rotating box 313 to rotate. At the same time, through the composite gear system composed of planetary gear 323 and auxiliary gear 324, the internal fine screen water pipe 316 and the frustum-shaped spiral rod 312 are synchronously driven to rotate. This composite transmission causes the screw rod 312 and the rotating box 313 to rotate at high speed in opposite directions. Under the dual centrifugation and extrusion, an extremely strong mechanical water-cutting shear force is formed on the surface of the fine filter pores 3131. This not only forces tiny impurities into the plate and frame filter press 33, but also achieves efficient physical self-cleaning of the fine filter pores, preventing clogging. The ultrafiltration box 42 is tightly connected to an optical fiber mesh 43, which evenly diffuses ultraviolet light into the entire water body. Combined with the gas-liquid phase change separation of the air valve 44 and the condenser plate 45, it enables the discharge of qualified water after sterilization.
