Description

TECHNICAL FIELD

[0001] The utility model relates to medical waste treatment technical field, concretely is a medical waste dewatering treatment device. BACKGROUND

[0002] In the daily operation of the medical industry, a large amount of medical waste containing infectious, pathological, damaging and other types of medical waste will be generated. If such waste is not properly treated, it will easily cause environmental pollution, spread of bacteria and pose a serious threat to public health and safety. Among them, the medical waste often contains a high moisture content, which not only increases the overall volume and weight of the waste, resulting in a significant increase in transportation costs, but also provides a suitable environment for the growth of microorganisms, further increasing the safety risks in the subsequent processing process. Therefore, efficient dewatering of medical waste becomes a key link in the harmless and reduction of medical waste processing. At present, there are many types of dewatering devices for medical waste in the prior art, the common ones mainly include squeezing type dewatering devices, centrifugal type dewatering devices, etc. The squeezing type dewatering device usually separates water by applying a certain pressure to the medical waste. However, such devices generally have the problem of incomplete dewatering, especially for some medical waste with high fiber content or loose texture, the pressure is difficult to uniformly act on the inside of the waste, resulting in some water remaining in the waste, which cannot effectively achieve the reduction processing goal.

[0003] In addition, the existing medical waste dewatering treatment device generally ignores the simultaneous disinfection of the waste during the processing process. The bacteria carried by the medical waste during the dewatering process may spread through droplets, sewage and other means. If not disinfected in time and effectively, it will increase the risk of cross infection. Therefore, the technical personnel in the field provide a medical waste dewatering treatment device to solve the problems raised in the above background technology. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a medical waste dewatering treatment device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: A medical waste dewatering treatment device, comprising: The utility model provides a dehydration tank, which is provided with a feeding cover, two extrusion rollers are rotatably connected to the dehydration tank, a filter plate is connected to the dehydration tank through a buffer assembly, an ultrasonic vibrator is installed on the filter plate, a conveying belt is connected to the dehydration tank through a conveying roller, and the conveying belt is arranged on one side of the filter plate, a transmission assembly is installed on the dehydration tank to drive the operation of the extrusion rollers and the conveying roller, a push plate is installed on the dehydration tank through an electric push rod, a cleaning brush for cleaning the filter plate is installed on the push plate, and a collection tank is arranged on one side of the conveying belt. An infrared baking lamp and an ultraviolet disinfection lamp are arranged on the dehydration tank in a staggered manner and above the conveying belt.

[0006] Preferably, the transmission assembly comprises a driving motor, a rotating rod, two meshed gear plates, two pulleys and a transmission belt, one of the extrusion rollers is connected to one of the gear plates through the rotating rod, one of the pulleys is connected to one of the gear plates, the other pulley is connected to the conveying roller through the rotating rod, the driving motor is installed on the dehydration tank, the output end of the driving motor is connected to one of the gear plates, and the two pulleys are connected through the transmission belt.

[0007] Preferably, the buffer assembly comprises a telescopic rod, a disc spring and a mounting plate, the mounting plate is fixedly installed in the dehydration tank, the disc spring is sleeved outside the telescopic rod, and the disc spring and the telescopic rod are respectively connected to the mounting plate and the filter plate.

[0008] Preferably, a plurality of through holes are formed in the filter plate, and the through holes are circular truncated cone holes.

[0009] Preferably, a mounting groove is formed in the dehydration tank, the collection tank is slidably connected in the mounting groove, a handle is installed on the collection tank, and an ultrasonic sensor is installed in the collection tank.

[0010] Preferably, a drainage pipe is installed on the dehydration tank, and a control valve is installed on the drainage pipe.

[0011] Preferably, a controller is installed on the dehydration tank, and the controller is electrically connected between the ultrasonic vibrator, the electric push rod, the infrared baking lamp, the ultraviolet disinfection lamp, the driving motor, the ultrasonic sensor and the control valve.

[0012] Compared with the prior art, the medical waste dewatering treatment device has the advantages that: the multiple dewatering structure design of "extrusion roller + ultrasonic vibrator + infrared baking lamp" effectively solves the problem of incomplete dewatering in the prior art. First, the two extrusion rollers can preliminarily mechanically press the medical waste to quickly separate most of the free water; second, the ultrasonic vibrator installed on the filter plate can generate high-frequency vibration, which can promote the separation of water remaining in the waste, especially for waste with high fiber content and loose texture, and the vibration effect can make water more easily penetrate to the lower side of the filter plate, and on the other hand, it can also avoid the blockage of waste particles in the filter plate pores, ensuring smooth dewatering process; finally, the infrared baking lamp above the conveying belt can heat and dry the extruded waste, further removing residual water. Compared with the traditional single pressing or centrifugal dewatering method, the dewatering efficiency and completeness of the device are significantly improved, and the medical waste can be minimized to the greatest extent, reducing the subsequent transportation cost. The medical waste dewatering treatment device realizes the simultaneous dewatering and disinfection, and the disinfection effect is more comprehensive, solving the problem of ignoring simultaneous disinfection of the existing device. The ultraviolet disinfection lamp staggered in the dewatering tank can irradiate the surface and internal gap of the waste with ultraviolet light in all directions during the movement of the waste with the conveying belt, effectively killing bacteria and preventing cross infection. At the same time, the infrared baking lamp plays a drying role, and the high temperature generated by the infrared baking lamp can also assist in killing part of the high-temperature-resistant bacteria, forming a "ultraviolet + high temperature" double disinfection mode. Compared with the existing device lacking disinfection function or single disinfection mode, the disinfection coverage of the medical waste dewatering treatment device is wider, and the sterilization effect is more reliable, further ensuring the public health safety in the medical waste treatment process.

DETAILED DESCRIPTION

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0015] Please refer to Figures 1-6 The utility model provides a technical scheme: A medical waste dehydration treatment device, comprising: The dehydration tank 1 is provided with a feed cover 2, two extrusion rollers 3 are rotatably connected to the dehydration tank 1, a filter plate 4 is connected to the dehydration tank 1 through a buffer assembly, a plurality of through holes 22 are formed in the filter plate 4, the plurality of through holes 22 are circular truncated cone holes, an ultrasonic vibrator 5 is mounted on the filter plate 4, a conveying belt 6 is connected to the dehydration tank 1 through a conveying roller 7, the conveying belt 6 is arranged on one side of the filter plate 4, a transmission assembly for driving the extrusion rollers 3 and the conveying roller 7 to operate is mounted on the dehydration tank 1, a push plate 9 is mounted on the dehydration tank 1 through an electric push rod 8, a cleaning brush 10 for cleaning the filter plate 4 is mounted on the push plate 9, a collection box 11 is arranged on one side of the conveying belt 6, a mounting groove 23 is formed in the dehydration tank 1, the collection box 11 is slidably connected in the mounting groove 23, a handle 24 is mounted on the collection box 11, and an ultrasonic sensor 25 is mounted in the collection box 11. Specifically, the transmission assembly comprises a drive motor 14, a rotating rod 15, two meshed gear discs 16, two pulleys 17 and a transmission belt 18, the two extrusion rollers 3 are connected to the gear discs 16 through the rotating rod 15, one of the pulleys 17 is connected to one of the gear discs 16, the other pulley 17 is connected to the conveying roller 7 through the rotating rod 15, the drive motor 14 is mounted on the dehydration tank 1, the output end of the drive motor 14 is connected to one of the gear discs 16, and the two pulleys 17 are connected through the transmission belt 18.

[0016] The buffer assembly comprises a telescopic rod 19, a disc spring 20 and a mounting plate 21, the mounting plate 21 is fixedly installed in the dehydration tank 1, the disc spring 20 is sleeved outside the telescopic rod 19, and the two ends of the disc spring 20 and the telescopic rod 19 are connected with the mounting plate 21 and the filter plate 4 respectively.

[0017] The medical waste is put into through the feeding cover 2 on the dehydration tank 1, and the waste first falls between the two rotating extrusion rollers 3. From the transmission principle, the output end of the driving motor 14 directly drives one of the gear plates 16 to rotate, the two gear plates 16 are engaged with each other, thereby driving the other gear plate 16 to rotate in the opposite direction, and the two extrusion rollers 3 are driven to rotate in the opposite direction through the rotating rod 15, so as to apply pressure to the waste to realize preliminary mechanical dehydration, and most of the separated water drops downward to the filter plate 4. This transmission mode can make the conveying roller 7 and the extrusion roller 3 keep cooperative operation, ensure the continuity of the waste treatment process, and lay a foundation for subsequent deep treatment, which is the first step of efficient dehydration compared with the traditional single dehydration device. The waste after preliminary dehydration falls on the filter plate 4, at this time the ultrasonic vibrator 5 on the filter plate 4 starts to work, based on the dehydration principle, the high-frequency vibration generated by the ultrasonic vibrator 5 can make the water molecules in the waste move violently, break the adsorption state of the water in the fiber structure, realize deep dehydration, and the water is collected downward through the circular truncated cone-shaped through hole 22 on the filter plate 4. At the same time, the buffer assembly plays a role, which is composed of the telescopic rod 19, the disc spring 20 and the mounting plate 21, the mounting plate 21 is fixed in the dehydration tank 1, the two ends of the telescopic rod 19 and the disc spring 20 are connected with the mounting plate 21 and the filter plate 4 respectively, when the waste falls on the filter plate 4, the filter plate 4 is subjected to downward pressure, the telescopic rod 19 is contracted, the disc spring 20 is compressed and generates a reverse elastic force, which buffers the impact of the waste on the filter plate 4, and can also adaptively adjust the height of the filter plate 4 according to the pressure, so that the filter plate 4 always maintains a stable filtering angle, avoiding the blockage of the through hole 22. Compared with the ordinary round hole, the circular truncated cone-shaped through hole 22 can not only ensure that the water passes through smoothly, but also reduce the situation that the waste particles are stuck in the through hole 22, and cooperate with the action of the ultrasonic vibrator 5, so that the filter plate 4 can be kept unobstructed for a long time, ensuring the stability of the dehydration efficiency, which fully embodies the beneficial effects that the device has higher dehydration efficiency, stable filtering effect and stronger running stability, effectively prolonging the service life of the filter plate 4.

[0018] When a small amount of waste impurities adhere to the surface of the filter plate 4, the controller 28 will automatically control the electric push rod 8 to extend according to the preset program or the use time of the filter plate 4, drive the push plate 9 to move, and the cleaning brush 10 on the push plate 9 synchronously cleans the surface of the filter plate 4 to prevent the circular table-shaped through hole 22 from being blocked. This process does not require manual cleaning, reducing the workload of manual maintenance, and further highlighting the advantages of intelligent device and convenient operation. The cleaned waste is pushed into the conveyor belt 6 by the push plate 9, the belt pulley 17 connected with one of the gear plates 16 in the transmission assembly rotates synchronously with the gear plate 16, and the other belt pulley 17 connected with the conveying roller 7 is driven to rotate through the transmission belt 18, driving the conveyor belt 6 to transport the waste to the collection box 11 direction, ensuring the smoothness of waste transportation.

[0019] The disinfected waste finally falls into the collection box 11, and the ultrasonic sensor 25 in the collection box 11 monitors the waste accumulation height in real time. When the preset value is reached, the sensor sends a signal to the controller 28, prompting the worker to pull out the collection box 11 from the installation slot 23 for cleaning through the handle 24. The sliding collection box 11 is designed for easy installation and removal, and the real-time monitoring of the ultrasonic sensor 25 avoids the omission of manual inspection and prevents the collection box 11 from overflowing due to excessive accumulation.

[0020] Further, the dehydration tank 1 is provided with a drainage pipe 26, and the drainage pipe 26 is provided with a control valve 27.

[0021] Opening the control valve 27 on the drainage pipe 26 can discharge the wastewater collected below the filter plate 4 through the drainage pipe 26, which is convenient for centralized treatment of wastewater and avoids environmental pollution.

[0022] The dehydration tank 1 is provided with staggered infrared baking lamps 12 and ultraviolet disinfection lamps 13, and the infrared baking lamps 12 and the ultraviolet disinfection lamps 13 are arranged above the conveying belt 6.

[0023] In the above embodiment, the dehydration tank 1 is provided with a controller 28, and the controller 28 is electrically connected with the ultrasonic vibrator 5, the electric push rod 8, the infrared baking lamp 12, the ultraviolet disinfection lamp 13, the drive motor 14, the ultrasonic sensor 25 and the control valve 27.

[0024] During the movement of the waste along the conveying belt 6, the infrared baking lamp 12 and the ultraviolet disinfection lamp 13 arranged alternately in the dehydration tank 1 work synchronously. From the dehydration principle, the infrared baking lamp 12 improves the temperature of the waste through radiation heating, accelerates the evaporation of moisture, and realizes further dehydration; from the disinfection angle, the ultraviolet disinfection lamp 13 disinfects the waste in all directions, and the high temperature generated by the infrared baking lamp 12 can also assist in killing part of the high-temperature-resistant bacteria, forming a double effect of "drying + disinfection". This synchronous processing mode not only greatly improves the dehydration efficiency and thoroughness, but also completely kills the bacteria and reduces the cross-infection risk, which embodies the characteristics that the device has stronger operation safety.

[0025] It should be noted that the specific model specifications of the controller 28, the ultrasonic vibrator 5, the electric push rod 8, the infrared baking lamp 12, the ultraviolet disinfection lamp 13, the driving motor 14, the ultrasonic sensor 25 and the control valve 27 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.

[0026] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
