Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0079] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0080] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0081] After medical solid waste is crushed, a small amount of liquid medicine will remain in the medicine bottles and injection tubes. The crushed solid waste and the liquid medicine will be mixed together, which takes a long time during high-temperature disinfection, affecting the efficiency of medical solid waste treatment.

[0082] In view of this, the present invention provides a treatment device for medical solid waste in a square cabin, including a treatment box 1, a liquid collecting box 2, a collecting tank 3, a conical screen 4 and a driving mechanism; the liquid collecting box 2 has an opening, and is fixed in the treatment box 1 through a fixing rod 30 with the opening facing upward; the collecting tank 3 is outside the treatment box 1 and lower than the liquid collecting box 2, and the top of the collecting tank 3 is connected to the bottom of the liquid collecting box 2 through a drain pipe 5; the conical screen 4 is in the treatment box 1, and is rotatably matched with the liquid collecting box 2 in a posture of covering the opening, and its conical surface is outside the liquid collecting box 2; the driving mechanism is arranged in the treatment box 1, and is transmission-connected to the conical screen 4 to drive the conical screen 4 to rotate around its own axis.

[0083] In the medical solid waste treatment equipment in the square cabin, the conical screen 4 plays a diversion role to realize the automatic separation of liquid and solid, wherein the liquid waste flows into the liquid collecting box 2 through the sieve holes of the conical screen 4 and enters the collection tank 3 through the drain pipe 5, while the solid waste is isolated and evenly dispersed in the treatment box 1 with the cooperation of the driving mechanism and the conical screen 4.

[0084] It can be seen that compared with the existing technology, the medical solid waste treatment equipment in the modular cabin effectively avoids the mixing of solids and liquids, making liquid collection more convenient, while ensuring the uniformity of solid dispersion and effectively alleviating the problem of heat concentration; after the separation of solids and liquids, the heating demand during high-temperature disinfection is reduced, the disinfection time is greatly shortened, and the treatment efficiency is improved.

[0085] The following combination Figures 1 to 10 The structure and shape of the medical solid waste treatment equipment provided in this embodiment are described in detail:

[0086] refer to Figures 1 to 3 The processing equipment for medical solid waste in the square cabin also includes a crushing mechanism; the crushing mechanism includes a feed hopper 9 and a crushing roller 10; the feed hopper 9 is fixed to the top of the processing box 1 and is connected to the processing box 1, and its bottom outlet is facing the top of the conical screen 4; the crushing roller 10 is in the feed hopper 9, and there is at least one pair of crushing rollers 10, in each pair, the two crushing rollers 10 are distributed in parallel on the horizontal plane, and both rotate with the feed hopper 9.

[0087] As mentioned above, a first rotating shaft 6 is fixed on the conical screen 4, the upper end of the first rotating shaft 6 is fixed to the top of the conical screen 4, and the other end extends along the axial direction of the conical screen 4 to pass through the liquid collecting box 2; a second rotating shaft 11 is provided at both ends of each crushing roller 10, and the second rotating shaft 11 is passed through the side wall of the feed hopper 9.

[0088] Continuing with the above, the driving mechanism includes a turbine 7, a worm 8, a gear 12 and a driver; the turbine 7 is located below the liquid collecting box 2 and is fixed to the first rotating shaft 6; the worm 8 rotates with the processing box 1 and is also meshed with the turbine 7; the gear 12 corresponds to the crushing rollers 10 one by one and is fixed to the second rotating shaft 11, and the gears 12 on adjacent crushing rollers 10 are meshed with each other; the driver adopts a motor, and the output part of the motor is connected to one end of one of the second rotating shafts 11.

[0089] Continuing with the above, optionally, the first rotating shaft 6 and the second rotating shaft 11 are belt-driven. Specifically, a driven wheel 32 is fixed to one end of the first rotating shaft 6, and a driving wheel 31 is fixed to the other end of the second rotating shaft 11. A transmission belt 33 is sleeved and tensioned on the driving wheel 31 and the driven wheel 32.

[0090] When in use, by setting up the treatment box 1, the treatment box 1 is placed on the ground with the support of an external bracket to improve the stability of the device; through the feed hopper 9 set on the treatment box 1, and the feed hopper 9 is connected with the inner cavity of the treatment box 1, the medical solid waste can be put into the treatment box 1 through the feed hopper 9; through the crushing roller 10 set on the feed hopper 9, and the gear 12 set on the crushing roller 10, the teeth on the two adjacent gears 12 are meshed with each other. When crushing, the medical solid waste is put on the top of the crushing roller 10, and one of the crushing rollers 10 is driven to rotate by the motor, so that the two crushing rollers 10 rotate relatively under the action of the gear 12 and crush the medical solid waste above, and the crushed medical solid waste and liquid fall into the inside of the treatment box 1 through the bottom of the feed hopper 9.

[0091] Through the fixing rod 30 arranged on the processing box 1 and the liquid collecting box 2 arranged on the fixing rod 30, the fixing rod 30 can fix and support the liquid collecting box 2 in the processing box 1; through the conical screen 4 arranged on the liquid collecting box 2, the conical screen 4 is rotatably connected to the inner wall of the liquid collecting box 2, and the top of the conical screen 4 corresponds to the outlet position of the bottom end of the feed hopper 9, and the medical solid waste and liquid crushed from the feed hopper 9 will be discharged to the top of the conical screen 4, wherein the medical solid waste will roll down along the inclined surface of the outer side of the conical screen 4, and the liquid will fall from the sieve holes on the inclined surface of the outer side of the conical screen 4 into the liquid collecting box 2; as the second rotating shaft 11 rotates with a rigid body fixed axis, the worm 8 drives the turbine 7 to rotate, thereby causing the conical screen 4 to rotate around its own axis. At this time, under the action of centrifugal force, the medical solid waste will be evenly dispersed in the processing box 1, thereby improving the separation effect of the conical screen 4 on medical solid waste and liquid.

[0092] By adopting the above design, the crushed medical solid waste and liquid can be separated, so as to facilitate the subsequent high-temperature disinfection and drying treatment of the medical solid waste; the liquid is discharged into the collection tank 3 through the drain pipe 5, and the collection tank 3 and the drain pipe 5 are detachably connected, so as to facilitate subsequent personnel to centrally treat the liquid inside the collection tank 3.

[0093] refer to Figure 4 The equipment for treating solid waste from square cabin medical facilities also includes a receiving hopper 13, a vibrating mechanism and an air blowing mechanism; the receiving hopper 13 is located below the liquid collecting box 2, and its opening faces the liquid collecting box 2, and the edge of the receiving hopper 13 is in contact with the inner wall of the treatment box 1; the vibrating mechanism is connected to the receiving hopper 13; the driving mechanism is transmission-connected to the vibrating mechanism to drive the vibrating mechanism to start and make the receiving hopper 13 vibrate in the longitudinal direction; the air blowing mechanism is connected to the vibrating mechanism and can blow air into the receiving hopper 13 under vibration conditions.

[0094] Regarding the vibration mechanism, specifically:

[0095] refer to Figures 4 to 6 Preferably, two groups of vibration mechanisms are provided, and are symmetrically distributed about the axis of the receiving hopper 13. The vibration mechanism includes a transmission rod 14, a connecting rod 15 and a first elastic component; the transmission rod 14 is longitudinally penetrated in the receiving hopper 13, and a first stopper 16 is fixed on the side wall below the receiving hopper 13; the connecting rod 15 is parallel to the transmission rod 14, and its top end is fixed to the bottom wall of the receiving hopper 13, and two second stops 17 are fixed on the side wall; in the axial direction of the connecting rod 15, the two second stops 17 are spaced apart, and are also distributed on both sides of the first stopper 16, and are opposite to the first stopper 16.

[0096] As mentioned above, a cylindrical block 18 is fixed to the bottom end of the first rotating shaft 6, and a sliding groove 181 is provided on the side wall of the cylindrical block 18, and the sliding groove 181 extends in a "V" shape along the circumference of the cylindrical block 18; the transmission rod 14 is "L"-shaped, and a section thereof perpendicular to the axis of the cylindrical block 18 is inserted into the sliding groove 181.

[0097] Continuing with the above, a support block 34 is fixed on the side wall of the processing box 1, and the support block 34 is arranged horizontally; the first elastic component includes an insertion rod 19, a sliding rod 20 and a first spring 21; the insertion rod 19 has a first end and a second end which are respectively located inside and outside the sliding rod 20, the first end can slide along the axial direction of the sliding rod 20, and the second end is fixed with a first connecting seat 22; the end of the sliding rod 20 away from the insertion rod 19 is fixed with a second connecting seat 23; one of the first connecting seat 22 and the second connecting seat 23 is hinged to the connecting rod 15, and the other is hinged to the support block 34; the first spring 21 is sleeved on the insertion rod 19 and the sliding rod 20, one end of which is connected to the first connecting seat 22, and the other end is connected to the second connecting seat 23

[0098] refer to Figure 4Through the first block set on the transmission rod 14 and the two second blocks set on the connecting rod 15, the first block can cooperate with the two second blocks respectively; in the initial state, the first block conflicts with the second block below, the insertion rod 19, the sliding rod 20 and the first spring 21 are connected obliquely upward between the connecting rod 15 and the support block 34, and the first elastic component supports the docking hopper 13 through the connecting rod 15.

[0099] Combination Figures 2 to 4 As shown, when the conical screen 4 rotates, the columnar block 18 rotates synchronously with the first rotating shaft 6, so that the transmission rod 14 slides along the extension path of the sliding groove 181, thereby performing reciprocating movement in the longitudinal direction.

[0100] As described above, when the transmission rod 14 moves in the downward vertical direction, the first block pushes the second block below to move downward under the action of the transmission rod 14, so that the connecting rod 15 and the receiving hopper 13 move synchronously in the downward vertical direction. At the same time, the first connecting seat 22 pushes the insertion rod 19 to move in the direction close to the second connecting seat 23 under the action of the connecting rod 15, so that the first spring 21 is squeezed and contracted under the action of the first connecting seat 22; when the first connecting seat 22 moves to below the support block 34, under the action of the restoring force of the first spring 21, the insertion rod 19 and the first connecting seat 22 quickly push the connecting rod 15 and the receiving hopper 13 to move in the downward direction. When the connecting rod 15 moves to the second block above and conflicts with the first block, the receiving hopper 13 vibrates and turns over the medical solid waste on its surface.

[0101] Continuing with the above, when the transmission rod 14 is reset and moved in the upward vertical direction, the first block drives the connecting rod 15 and the receiving hopper 13 to move upward synchronously through the second block above, and at the same time, the first spring 21 is squeezed and contracted under the action of the first connecting seat 22; when the first connecting seat 22 moves to be higher than the support block 34, under the action of the restoring force of the first spring 21, the insertion rod 19 and the first connecting seat 22 quickly push the connecting rod 15 and the receiving hopper 13 to move in the upward direction, and the second block below conflicts with the first block, generating vibration, so that the receiving hopper 13 throws the medical solid waste on its surface upward.

[0102] In the above design, as the columnar block 18 continues to rotate, the receiving hopper 13 generates upward and downward reciprocating vibrations, thereby increasing the heat exchange effect of the medical solid waste and avoiding uneven heat distribution caused by the accumulation of medical solid waste.

[0103] Regarding the blowing mechanism, specifically:

[0104] refer to Figures 6 to 8Preferably, the blowing mechanism corresponds to the vibration mechanism one by one, including a sleeve 24, an air bag 25 and an air pump 26; the sleeve 24 is sleeved on the transmission rod 14 and fixed to the receiving hopper 13, and a plurality of air outlet holes 241 extending along its own circumference are provided on its side wall, and a conical guide ring 27 is also fixed; the air outlet holes 241 are located in the guide ring 27, the large end of the guide ring 27 faces upward, and the side wall thereof contacts the inner wall of the receiving hopper 13; the transmission rod 14 is a tubular structure, the upper end of which is closed and inserted into the sliding groove 181, and the lower end is connected to the air bag 25, and a plurality of air vents 141 corresponding to the air outlet holes 241 are provided on the side wall of the transmission rod 14; the air vents 141 are located in the sleeve 24, and are connected to the air outlet holes 241 in the initial state; the air pump 26 is connected to the air bag 25, and its input part is connected to the connecting rod 15.

[0105] As mentioned above, the air pump 26 includes a main body 261, a piston 262, an air inlet pipe 263 and an air exhaust pipe 265; the main body 261 is cylindrical, fixed in the treatment box 1, and its upper end is open and the lower end is closed; the piston 262 is in the main body 261, and can move along the axial direction of the main body 261, and its side surface is sealed with the inner wall of the main body 261; the lower end of the connecting rod 15 is fixed to the piston 262; an air inlet valve 264 is fixed in the air inlet pipe 263, one end of which is connected to the main body 261 and is close to the bottom end of the main body 261; an exhaust valve 266 is fixed in the exhaust pipe 265, one end of which is connected to the airbag 25, and the other end is connected to the main body 261 and is close to the bottom end of the main body 261.

[0106] refer to Figures 6 to 8 , and combined with Figure 4 As shown, when the connecting rod 15 drives the hopper 13 to move rapidly in the downward direction, the sleeve 24 moves synchronously under the action of the hopper 13, so that the air outlet 241 and the air vent 141 are dislocated and disengaged. At this time, the air vent 141 contacts the inner wall of the sleeve 24 and is blocked; the piston 262 moves toward the bottom end of the main body 261 under the action of the connecting rod 15. At this time, the air inlet valve 264 is in a closed state and the exhaust valve 266 is in an open state, so that the gas inside the main body 261 is discharged into the airbag 25, and the airbag 25 expands.

[0107] As mentioned above, when the connecting rod 15 drives the receiving hopper 13 to move rapidly in the upward direction, the piston 262 moves synchronously toward the top close to the main body 261 under the drive of the connecting rod 15. At this time, the air inlet valve 264 is in an open state, and the exhaust valve 266 is in a closed state. The piston 262 draws external gas into the interior of the main body 261 through the air inlet pipe 263; when the receiving hopper 13 moves upward to the second block below and collides with the first block, the air outlet 241 is connected to the vent 141. At this time, the gas inside the airbag 25 is discharged through the vent 141 and the air outlet 241, and flows upward under the guidance of the guide ring 27, thereby blowing the thrown medical solid waste.

[0108] The above design can accelerate the evaporation of water on the surface of medical solid waste, help remove excess water on its surface, accelerate the drying process of medical solid waste, and further improve the treatment efficiency of medical solid waste.

[0109] In this example, refer to Fig. 9 and Fig.10 , and combined with Figure 4 As shown, the medical solid waste treatment equipment in the square cabin also includes a discharge pipe 28, a cover plate 29 and a second elastic component; the discharge pipe 28 is fixed to the treatment box 1 and extends longitudinally; the bottom end of the receiving hopper 13 is sleeved on the discharge pipe 28; the second elastic component is arranged on the discharge pipe 28 and connected to the cover plate 29, which is used to drive the cover plate 29 to move longitudinally to close or open the top pipe opening of the discharge pipe 28.

[0110] Specifically, Fig. 9 and Fig.10 As shown, a limiting groove 281 is provided at the bottom end of the discharge pipe 28, and a supporting groove is provided in the side wall, wherein two limiting grooves 281 are provided and are symmetrically distributed about the axis of the discharge pipe 28, and two supporting grooves are also provided and both extend along the axial direction of the discharge pipe 28 and are symmetrically distributed about the axis of the discharge pipe 28; a limiting column 291 is protruded from the lower surface of the cover plate 29, and the limiting column 291 is adapted to the supporting groove one by one and inserted in the supporting groove; the second elastic component includes a columnar rod 36, a limiting rod 37 and a second spring 35; the upper end of the columnar rod 36 is fixedly connected to the cover plate 29; the limiting rod 37 is adapted to the limiting groove 281, and is connected to the lower end of the columnar rod 36, and is rotatably matched with the columnar rod 36; the second spring 35 is in the supporting groove, and its two ends are respectively connected to the limiting column 291 and the discharge pipe 28.

[0111] When applying, refer to Fig. 9In the initial state, the limit rod 37 contacts the bottom end of the discharge pipe 28. At this time, the cover plate 29 contacts the top end of the discharge pipe 28 to block the upper pipe opening of the discharge pipe 28, and the second spring 35 is in a compressed state. In this way, leakage is avoided during the treatment of medical solid waste. When the medical solid waste is treated, the personnel manually rotate the limit rod 37 to correspond to the limit groove 281. At this time, under the action of the restoring force of the second spring 35, the cover plate 29 is pushed upward and drives the limit rod 37 to move through the cylindrical rod 36, so that the limit rod 37 is in conflict with the bottom groove surface of the limit groove 281. At the same time, the cover plate 29 releases the blockage of the upper pipe opening, and the medical solid waste on the surface of the receiving hopper 13 can be discharged through the discharge pipe 28, so that the personnel can collect the treated medical solid waste in a centralized manner.

[0112] The beneficial effects of the present invention are as follows:

[0113] 1. By utilizing the meshing gears 12 provided on the pulverizing roller 10, the pulverizing roller 10 can rotate synchronously under the drive of the motor to pulverize the medical solid waste, and then the automatic separation of solid and liquid is realized through the diversion effect of the conical screen 4. The liquid waste flows into the liquid collecting box 2 through the sieve holes, and finally enters the collection tank 3 through the drain pipe 5, while the medical solid waste is guided to the receiving hopper 13, which effectively avoids the mixing of solid and liquid, makes liquid collection more convenient, and reduces the heating demand during high-temperature disinfection, greatly shortens the disinfection time, and improves the processing efficiency.

[0114] 2. The bidirectional vibration mechanism arranged at the bottom of the receiving hopper 13 realizes the periodic up and down vibration of the receiving hopper 13, so that the medical solid waste is thrown upward and turned over in the receiving hopper 13, and the heat exchange efficiency of the surface of the medical solid waste is improved, which helps to quickly achieve the drying effect. At the same time, the vibration design effectively loosens the medical solid waste before discharge, avoids possible adhesion during the drying process, and improves the discharge fluency and the convenience of subsequent collection.

[0115] 3. During the vibration of the receiving hopper 13, the airbag 25 blows air upward through the guide ring 27, and blows air in a directional manner on the medical solid waste thrown upward, blowing on the surface of the medical solid waste, causing the moisture on the surface to evaporate quickly, thereby accelerating the drying process.
