Description

Technical Field

[0001] This utility model relates to the field of medical waste treatment equipment, specifically a solid-liquid separation device for operating room waste. Background Technology

[0002] Operating room procedures continuously generate a large amount of mixed solid-liquid medical waste, mainly including blood-stained gauze, sealed drainage bags, disposable instruments, tissue fragments, and waste liquid packaging materials. This type of waste often carries pathogenic microorganisms, posing a high risk of infection. Effective separation of solid waste from liquids before collection and transportation helps reduce the risk of leakage from damaged packaging, ground contamination, and cross-infection within the hospital, while also reducing the burden on subsequent waste liquid treatment and medical waste disposal.

[0003] Existing solid-liquid separation equipment typically employs a process of crushing followed by compression, but a fixed spacing is often used between the two compression rollers. Due to the significant differences in thickness and hardness of surgical waste, a fixed spacing is insufficient to simultaneously handle different materials such as sealed drainage bags, soft dressings, and rigid disposable instruments: too small a spacing can easily cause material jamming or machine blockage, while too large a spacing can lead to insufficient compression force, leaving a significant amount of liquid residue inside the crushed sealed packaging, resulting in incomplete solid-liquid separation.

[0004] Furthermore, the fine impurities generated after crushing easily adhere to or become embedded in the filter pores of the filtration structure, leading to a decrease in filtration flux and requiring frequent shutdowns for cleaning. Therefore, it is necessary to provide a solid-liquid separation device for operating room waste that can adaptively adjust the crushing distance and reduce clogging of the filter structure. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a solid-liquid separation device for operating room waste that solves the problems of existing equipment being unable to adapt to medical waste of different thicknesses and hardnesses, insufficient extrusion of residual liquid in sealed packaging, and easy clogging of the filter structure.

[0006] The technical solution adopted by this utility model is as follows: A solid-liquid separation device for operating room waste includes a crushing box and an inclined feeding pipe connected to the bottom outlet of the crushing box, and also includes a separation mechanism, which includes a separation component disposed in the crushing box and a vibration component disposed in the inclined feeding pipe. The separation assembly includes two crushing rollers disposed on the upper layer and a pressing roller and multiple pressing section rollers disposed on the lower layer. The multiple pressing section rollers are spaced apart along the axial direction of the rotating rod two, and each pressing section roller is respectively limited and sleeved on the outside of the rotating rod two by a support rod. The support rod can slide radially relative to the rotating rod two, and a damping spring plate group for resetting the support rod is provided between the support rod and the rotating rod two. The inclined feeding tube is provided with a variable diameter rotating shaft, a spiral blade connected to the outer periphery of the variable diameter rotating shaft, and a semi-circular filter cylinder located outside the spiral blade; the vibration assembly includes an impact rod that rotates with the variable diameter rotating shaft and an impact arc block connected to the semi-circular filter cylinder. One end of the semi-circular filter cylinder is connected to the inner wall of the inclined feeding tube through a hinge rod, and the other end is elastically connected to the inclined feeding tube through a spring.

[0007] Through the above scheme, two crushing rollers can first crush the mixed medical waste, and then the extrusion roller and multiple extrusion segment rollers can squeeze the liquid out of the crushed waste. When the thickness or hardness of the waste changes, the corresponding extrusion segment rollers can move radially through the support rod and reset under the action of the damping spring assembly, thereby automatically adjusting the local extrusion gap, which can reduce the risk of material jamming and maintain a good extrusion effect. At the same time, the spiral blades can transport and extrude the waste again, and the vibration component can drive the semi-circular filter cylinder to vibrate, reducing the filter pores from being blocked by debris and making the solid-liquid separation process smoother.

[0008] Furthermore, the crushing chamber is also equipped with a guide plate for guiding the crushed medical waste to the space between the extrusion roller and the extrusion section roller.

[0009] Through the above scheme, the guide plate can guide the crushed medical waste in a concentrated manner, so that the waste enters the crushing area more accurately, reducing the situation of waste scattering or accumulating inside the crushing box, and improving the stability of continuous crushing and deliquescence.

[0010] Furthermore, the separation assembly also includes a motor, a gear, a gear, a shaft, a rotating rod, and a timing pulley set; the two crushing rollers are respectively fixedly sleeved on the outside of the two shafts, and one end of each of the two shafts is provided with a meshing gear; the extrusion roller is fixedly sleeved on the outside of the rotating rod, the extrusion section roller is disposed on the outside of the rotating rod, and one end of the rotating rod and the rotating rod are respectively provided with a meshing gear; the timing pulley set connects one of the gears and one of the gears to transmit the power of the gear to the gear.

[0011] With the above scheme, motor one can drive the crushing roller, extrusion roller and extrusion section roller to run simultaneously through gear one, synchronous belt pulley group and gear two, so that the crushing and extrusion processes are connected to each other, reducing the number of drive components and making the device structure more compact.

[0012] Furthermore, the second rotating rod is provided with a notch corresponding to the support rod, and the support rod passes through the notch and can slide radially relative to the second rotating rod.

[0013] Through the above scheme, the notch can restrict the movement direction of the support rod, so that the support rod can slide stably along the radial direction of the rotating rod, thereby ensuring that the extrusion section roller can reliably retract and reset, and avoiding significant deviation during operation.

[0014] Furthermore, the vibration assembly also includes a guide rod and a limiting plate. The guide rod is connected to the semi-circular filter cylinder and movably passes through the inclined feeding pipe. The limiting plate is connected to the end of the guide rod, and the spring is sleeved on the outside of the guide rod.

[0015] Through the above scheme, the guide rod can guide the vibration direction of the semi-circular filter cylinder, the limiting plate can prevent the guide rod from disengaging from the inclined feeding pipe, and the spring can push the semi-circular filter cylinder to reset after being impacted, thereby forming a stable and continuous reciprocating vibration.

[0016] Furthermore, the lower end of the inclined feeding pipe is connected to the bottom outlet of the crushing box, the higher end of the inclined feeding pipe is provided with a slag discharge pipe, and the bottom of the inclined feeding pipe is provided with a liquid discharge pipe.

[0017] With the above scheme, the spiral blades can push the waste to be conveyed obliquely upward along the inclined feeding pipe. The waste stays for a longer time in the process of overcoming gravity, providing more sufficient separation time for the liquid to pass through the semi-circular filter cartridge. The separated liquid can flow down the inner wall of the inclined feeding pipe and be discharged through the drain pipe, while the solid waste after liquid removal is discharged through the slag discharge pipe at the higher end, thereby reducing the situation where liquid is discharged along with solid waste.

[0018] Furthermore, the variable diameter shaft is driven to rotate by a second motor, and the diameter of the variable diameter shaft gradually increases along the material conveying direction, so that a gradually decreasing material channel is formed between the spiral blades and the semi-circular filter cylinder.

[0019] With the above scheme, when the motor drives the variable diameter shaft and the spiral blade to rotate synchronously, the garbage can enter the gradually narrowing material channel during the conveying process and be squeezed again, thereby further squeezing out the residual liquid in the garbage and improving the thoroughness of solid-liquid separation.

[0020] Furthermore, the separation mechanism also includes a protective cover, which covers the transmission components outside the crushing box.

[0021] Through the above solution, the protective cover can isolate transmission components such as gears and synchronous belt pulleys from the external environment, reduce the possibility of accidental contact by personnel and the entry of garbage and sewage into the transmission components, and improve the safety and operational stability of the device.

[0022] Furthermore, the damping spring assembly and the spring are respectively provided with a telescopic protective sleeve one and a telescopic protective sleeve two.

[0023] Through the above solutions, telescopic protective sleeve one and telescopic protective sleeve two can shield and protect the damping spring assembly and spring extension and contraction without affecting them, reducing the adhesion of debris, fibers and dirt, thereby extending the service life of the elastic components.

[0024] The beneficial effects of this utility model are as follows: 1. It can automatically adjust the local compression gap according to the thickness and hardness of medical waste, making it less likely to get stuck when encountering harder or thicker waste, while also maintaining sufficient compression for soft waste such as gauze and drainage bags.

[0025] 2. After the waste is crushed, elastically squeezed, and further compressed by the variable diameter spiral structure, the residual liquid inside can be squeezed out more fully; the inclined feeding pipe can also extend the separation time of the waste, so that solid waste and liquid are separated more cleanly.

[0026] 3. The semi-circular filter cartridge can vibrate continuously with the cooperation of the impact rod and spring, which can shake off the debris attached to the filter holes, reduce filter cartridge clogging and the number of shutdowns for cleaning, and make the device operate more continuously and stably.

It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0032] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0033] like Figures 1-7 As shown, this embodiment provides a solid-liquid separation device for operating room waste, including a crushing box 111, an inclined feeding pipe 112, and a separation mechanism 2. The upper part of the crushing box 111 is provided with a feeding area for feeding mixed medical waste, and the bottom outlet of the crushing box 111 is connected to the lower end of the inclined feeding pipe 112; the higher end of the inclined feeding pipe 112 is provided with a slag discharge pipe 113, and the bottom of the inclined feeding pipe 112 is provided with a liquid discharge pipe 114, so that the separated solid residue and liquid are discharged separately.

[0034] The separation mechanism 2 includes a separation component 21 disposed in the crushing box 111 and a vibration component 22 disposed in the inclined feeding pipe 112; the separation component 21 includes a protective cover 211, a first motor 212, two crushing rollers 213, a guide plate 214, a squeeze roller 215, a second motor 216, multiple squeeze section rollers 217, a first gear 218, a second gear 219, a rotating shaft 210, a first rotating rod 2111, a second rotating rod 2112, and a synchronous belt pulley set 2113.

[0035] Two crushing rollers 213 are located on the upper layer inside the crushing chamber 111 and are fixedly sleeved on the outside of two parallel rotating shafts 210. One end of each rotating shaft 210 is equipped with a meshing gear 218, and the output end of a motor 212 is connected to one of the rotating shafts 210. When the motor 212 starts, it drives one of the crushing rollers 213 to rotate, and through the meshing of the two gears 218, it causes the other crushing roller 213 to rotate synchronously in the opposite direction, thereby clamping and tearing the medical waste that has entered the crushing chamber 111.

[0036] A guide plate 214 is positioned below the crushing roller 213 to receive the crushed medical waste and guide it between the lower-level compression roller 215 and multiple compression section rollers 217. The compression roller 215 is fixedly sleeved on the outside of the first rotating rod 2111, and the multiple compression section rollers 217 are arranged axially at intervals along the second rotating rod 2112. One end of the first rotating rod 2111 and the second rotating rod 2112 are respectively provided with meshing gears 219. A synchronous pulley set 2113 connects one of the gears 218 and one of the gears 219, enabling the first motor 212 to simultaneously drive the crushing roller 213, the compression roller 215, and the compression section rollers 217. The gears and synchronous pulley set and other transmission components outside the crushing box 111 are covered by a protective cover 211.

[0037] like Figures 3-5 As shown, the rotating rod 2112 has notches 2114 along its circumferential and axial directions corresponding to the support rods 2115. Each support rod 2115 passes through the corresponding notch 2114 and can slide back and forth radially along the rotating rod 2112. Each extrusion roller 217 is respectively limited and sleeved or connected to the outer end of the corresponding support rod 2115. A damping spring assembly 2116 is provided between the support rod 2115 and the rotating rod 2112. The damping spring assembly 2116 provides an elastic force to the support rod 2115 in the direction of the extrusion roller 215, and causes the support rod 2115 to return to its original position after being compressed and retracted.

[0038] When thick or hard waste enters between the extrusion roller 215 and the extrusion section roller 217, the corresponding extrusion section roller 217 can overcome the elastic force of the damping spring assembly 2116 and radially retract towards the rotating rod 2112, increasing the local extrusion gap and preventing the entire extrusion area from being jammed by hard materials. After the material passes through, the damping spring assembly 2116 pushes the support rod 2115 and the extrusion section roller 217 to reset. Since multiple extrusion section rollers 217 can operate independently, it can adapt to situations where the thickness of the material is inconsistent along the axial direction and maintain a sufficient extrusion effect on soft materials. The damping spring assembly 2116 is equipped with a telescopic protective sleeve 2117 to reduce the entry of debris, fibers, and sewage into the elastic components.

[0039] like Figure 1 , Figure 6 and Figure 7 As shown, a variable diameter rotating shaft 2118 is arranged along its length inside the inclined feeding pipe 112, and the variable diameter rotating shaft 2118 is driven by a motor 216. A spiral blade 2119 is connected to the outer periphery of the variable diameter rotating shaft 2118, and a semi-circular filter cylinder 2120 is arranged outside the spiral blade 2119. The open side of the semi-circular filter cylinder 2120 can face upwards to receive material falling from the crushing box 111, and its filter holes are used to allow liquid to pass through while trapping solid waste.

[0040] After being crushed and compressed, the medical waste falls into the inclined feeding pipe 112 through the outlet at the bottom of the crushing box 111. The second motor 216 is started, driving the variable-diameter shaft 2118 and the spiral blades 2119 to rotate synchronously. During rotation, the spiral blades 2119 continuously exert an upward conveying force on the medical waste along the inclined feeding pipe 112, causing the medical waste to gradually move towards the discharge pipe 113. The diameter of the variable-diameter shaft 2118 gradually increases along the material conveying direction from the crushing box 111 to the discharge pipe 113, creating a gradually decreasing material channel between the spiral blades 2119 and the semi-circular filter cylinder 2120. Therefore, during the rotation of the variable-diameter shaft 2118 and the material conveying process of the spiral blades 2119, the variable-diameter shaft 2118, with its variable-diameter structure and in conjunction with the spiral blades 2119, can continuously compress and squeeze the medical waste again, further squeezing out the residual liquid inside the waste, thereby improving the solid-liquid separation effect. Meanwhile, the inclined feeding pipe 112 is angled upwards from the end connected to the crushing box 111 to the end where the slag discharge pipe 113 is located. As the medical waste overcomes gravity and is conveyed upwards along the inclined feeding pipe 112, its conveying resistance and residence time increase accordingly. This provides more sufficient separation time for the liquid to seep out of the solid waste and pass through the semi-circular filter cylinder 2120, reducing the possibility of the liquid being discharged along with the solid waste through the slag discharge pipe 113 before it has had time to separate. The separated liquid falls into the interior of the inclined feeding pipe 112 after passing through the semi-circular filter cylinder 2120, and flows down the inner wall of the inclined feeding pipe 112 to a lower position, and is finally discharged through the liquid discharge pipe 114. The solid waste that has completed the liquid removal continues to be conveyed upwards under the push of the spiral blades 2119 and is discharged through the slag discharge pipe 113.

[0041] The vibration assembly 22 includes an impact rod 221, an impact arc block 222, a guide rod 223, a limiting plate 224, a spring 225, a telescopic protective sleeve 226, and a hinge rod 227. The impact rod 221 is connected to the variable diameter rotating shaft 2118 and rotates with it. The impact arc block 222 is connected to the semi-circular filter cylinder 2120. One end of the semi-circular filter cylinder 2120 is hinged to the inner wall of the inclined feed pipe 112 via the hinge rod 227, and the other end is connected to the guide rod 223. The guide rod 223 is movably inserted through the inclined feed pipe 112. One end of the guide rod 223 extending out of the inclined feed pipe 112 is connected to the limiting plate 224. The spring 225 is sleeved on the outside of the guide rod 223 and elastically abuts against the limiting plate 224 and the inclined feed pipe 112.

[0042] During the rotation of the variable-diameter shaft 2118, the impact rod 221 periodically contacts and passes over the impact arc block 222. When the impact rod 221 applies force to the impact arc block 222, the semi-circular filter cartridge 2120 deflects around the hinge rod 227, causing the guide rod 223 to move and compressing the spring 225. After the impact rod 221 passes over the impact arc block 222, the spring 225 pushes the guide rod 223 and the semi-circular filter cartridge 2120 back to their original positions. This creates periodic reciprocating vibrations, loosening fine impurities adhering to the surface of the semi-circular filter cartridge 2120 and inside the filter holes, reducing clogging of the filter structure. A telescopic protective sleeve 226 is provided outside the spring 225 to reduce the impact of dirt and debris on the operation of the spring 225.

[0043] When using this device, first start motor 212 and motor 216, then put the mixed medical waste from the operating room into the crushing box 111. The waste is first crushed by two counter-rotating crushing rollers 213, and then guided by the guide plate 214 into the space between the compression roller 215 and the compression section roller 217 to complete elastic compression and preliminary dehydration. The compressed material falls into the semi-circular filter cylinder 2120, and is conveyed to the slag discharge pipe 113 by the spiral blades 2119, and undergoes secondary compression in the gradually narrowing material channel. The separated liquid passes through the filter holes and is discharged from the liquid discharge pipe 114, while the solid residue is discharged from the slag discharge pipe 113; at the same time, the vibration component 22 continuously vibrates the semi-circular filter cylinder 2120 to keep the filter holes unobstructed.

[0044] Without altering the basic concept of this utility model, the surface of the crushing roller 213 may be provided with teeth, ridges, or other structures suitable for tearing medical waste; the filter hole size of the semi-circular filter cylinder 2120, the inclination angle of the inclined feed pipe 112, the elastic parameters of the damping spring assembly 2116, and the diameter variation range of the variable diameter rotating shaft 2118 can be selected according to the type of medical waste to be processed and the processing capacity. The specific structures described above do not constitute a limitation on the scope of protection of this utility model.

[0045] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
