Detailed implementation mode

[0025] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figure 1 , Figure 2 shown, this embodiment discloses a pharmaceutical residue disposal system, including a feeding device 1, a screw feeder 2, a buffer device 3, a crusher 4, a stirring device 5, a filter 6, a grinding pump 7, a fan 8, and a liquid inlet pipe 9. The feeding device 1 includes a feeding claw 11, a spraying device 12, and a bag breaking device 13. The feeding claw 11 grabs the material bag, and the bag breaking device 13 breaks the material bag. The feeding device 1 includes that the spraying device 12 is located between the feeding claw 11 and the bag breaking device 13. After the bag breaking device 13 breaks the packaging of the material bag, since dust will be generated after the bag breaking by the bag breaking device 13 and the dust will diverge outward from the inlet of the feeding claw 11, a spraying device 12 is installed on the side wall of the feeding device 1 above the bag breaking device 13. The dust generated by the bag breaking is pressed down by the water mist to prevent environmental pollution. An inverted V-shaped baffle is arranged inside the feeding device 1 to play a role in blocking and buffering the material bag and waste, preventing the waste from directly falling into the screw feeder 2 and causing blockage. The bag breaking device 13 can send out the emptied material bag packaging from the feeding device 1. The upper end of the feeding device 1 is connected to the fan 8, and the fan 8 continuously pumps air outwards, making the inside of the feeding device 1 in a slightly negative pressure environment. The waste gas generated by the volatilization of the waste inside the feeding device 1 can be pumped out and sent away by the fan 8, which can prevent the volatilization of toxic and harmful gases into the surrounding environment.

[0027] As shown Figure 2 in the figure, the lower end of the feeding device 1 is connected to the screw feeder 2, the discharge end of the screw feeder 2 is connected to the buffer device 3, the buffer device 3 includes a buffer box 31 and a vibrating device 32, the buffer box 31 includes a first cavity 311 and a second cavity 312, a first discharge port 3111 is provided at the lower end of the first cavity 311, the first discharge port 3111 is connected to the crusher 4, the second cavity 312 is located on the upper side of the first cavity 311, the second cavity 312 includes a feed inlet 3122, the feed inlet 3122 is connected to the screw feeder 2, the bottom surface of the second cavity 312 forms a slope 3121, one end of the slope 3121 close to the first cavity 311 slopes downward, the screw feeder 2 sends the waste to the feed inlet 3122, and the waste falls into the second cavity 312 from the feed inlet 3122. The waste falls onto the slope 3121 and slides down along the inclined slope 3121 towards the first cavity 311. The second cavity 312 can temporarily store the waste on the slope 3121 after the waste is fed, playing a buffering role in the waste feeding and preventing the waste from directly falling onto the first discharge port 3111 and causing blockage. The top of the buffer box 31 is connected to a blower 8, and the blower 8 can extract the waste gas in the buffer box 31 outwards, keeping the buffer box 31 in a slightly negative pressure state.

[0028] The vibrating device 32 includes a vibrating rod 321 and a driving device 322. The driving device 322 can drive the vibrating rod 321 to move up and down. The driving device 322 is installed on the top of the buffer box 31. The driving device 322 includes a motor 3221, a driving disk 3222, and a connecting rod 3224. The motor 3221 is fixedly installed on the buffer box 31, and the rotating shaft of the motor 3221 drives the driving disk 3222 to rotate. The driving disk 3222 is provided with a connecting end 3223. The connecting end 3223 is located in the rotation direction of the driving disk 3222. When the driving disk 3222 rotates, it can drive the connecting end 3223 to move in a circular trajectory. One end of the connecting rod 3224 is rotatably connected to the connecting end 3223, and the other end of the connecting rod 3224 is rotatably connected to the vibrating rod 321. When the driving disk 3222 rotates, it can drive the vibrating rod 321 to reciprocate up and down, so that the vibrating head 3211 can vibrate up and down. The buffer box 31 is provided with a bushing 323, and the vibrating rod 321 passes through the bushing 323 and slides along the bushing 323. The bushing 323 has the functions of sealing and guiding the movement of the vibrating rod 321.

[0029] At least part of the vibrating rod 321 is located inside the buffer box 31. A vibrating head 3211 is provided at the lower end of the vibrating rod 321. The waste entering the buffer box 31 collides with the vibrating head 3211. More preferably, the vibrating head 3211 is located inside the first cavity 311, and the vibrating head 3211 is close to the inner side wall of the first cavity 311 where the first cavity 311 is connected to the second cavity 312. The vibrating head 3211 being closer to the second cavity 312 can better receive the waste falling from the second cavity 312.

[0030] The material shaking head 3211 shakes along with the up and down movement of the material shaking rod 321. When the waste material falling from the second cavity 312 contacts the material shaking head 3211, the waste material will collide with the material shaking head 3211 that shakes up and down, and the waste material will be scattered by the material shaking head 3211. The waste material that forms into large pieces is scattered into small pieces and falls into the waste liquid in the first cavity 311, preventing the large waste material from blocking the first discharge port 3111, and ensuring better crushing effect of the crusher. The material shaking head 3211 includes a first material shaking frame 32111 and a second material shaking frame 32112. The first material shaking frame 32111 and the second material shaking frame 32112 are arranged at an interval up and down. Both the first material shaking frame 32111 and the second material shaking frame 32112 are provided with a plurality of rods arranged at intervals. When the waste material contacts the rods, it will be impacted and scattered by the rods. The small waste material can pass through between two adjacent rods. The waste material stuck between the two rods will fall along with the shaking of the material shaking head 3211 and the subsequent collision of the waste material. The rods located in the first material shaking frame 32111 and the rods located in the second material shaking frame 32112 are arranged in a staggered manner. The waste material passing through between the rods of the first material shaking frame 32111 will collide with the rods of the second material shaking frame 32112 and then have a secondary collision after falling, so that the waste material can be broken more evenly, and the part of the waste material remaining on the material shaking head 3211 will also fall along with the up and down shaking of the material shaking head 3211.

[0031] As Figure 1 shown, the first discharge port 3111 of the buffer device 3 is connected to the crusher 4. The discharge end of the crusher 4 is connected to the stirring device 5. The stirring device 5 is installed with a rotatable stirring rod 51. The stirring rod 51 is of a spiral ribbon type and can scrape the inner wall of the stirring device 5 while stirring. The spiral ribbon type stirring rod 51 can better stir the relatively viscous slurry, so that the crushed waste material and waste water are fully mixed. The discharge end of the stirring device 5 is connected to the filter 6. The filter 6 is a Lan's filter and can filter out the too large impurities in the stirred slurry to prevent the impurities from jamming and wearing out the grinding pump 7. The discharge end of the filter 6 is connected to the grinding pump 7. The stirring device 5 is provided with a second liquid inlet 52. The liquid inlet pipe 9 is connected to the second liquid inlet 52. The liquid inlet pipe 9 conveys waste water. The waste water is used to mix with the waste material to form a slurry. The waste water can be used to carry the waste material for transmission, and the waste water can be recycled and reused to make slurry, saving resources.

[0032] The stirring device 5 is installed with a second liquid level sensor 53. The liquid inlet pipe 9 is provided with a second control valve 91. The second liquid level sensor 53 is connected to the second control valve 91. The second liquid level sensor 53 can sense the liquid level height in the stirring device 5. Before preparing the slurry, the amount of waste water injected into the stirring device 5 is sensed by the second liquid level sensor 53. When the liquid level of the waste water in the stirring device 5 reaches the specified position, the second liquid level sensor 53 sends a signal to close the second control valve 91, so as to control the amount of the final slurry output according to the ratio. The top of the stirring device 5 is connected to a blower 8, and the blower 8 can extract the waste gas in the stirring device 5 outwards, so that the stirring device 5 maintains a slightly negative pressure state.

[0033] The grinding pump 7 is connected to an output pipeline 71. The output pipeline 71 includes a first pipeline 711, a second pipeline 712, and a third pipeline 713. The first pipeline 711 is used to send the completed slurry to the rear end. The screw feeder 2 is provided with a first liquid inlet 21. The first liquid inlet 21 is located at the discharge end of the screw feeder 2. The second pipeline 712 is connected to the first liquid inlet 21. The second pipeline 712 connects the grinding pump 7 and the buffer tank 31, so that the buffer tank 31, the crusher 4, the stirring device 5, the filter 6, and the grinding pump 7 are connected, so that the waste water, waste materials, and slurry are circulated, broken, ground, and mixed in the circulation loop. The waste water and slurry passing through the grinding pump 7 can be sent to the discharge end of the screw feeder 2 through the second pipeline 712, which can prevent the discharge end of the screw feeder 2 from being blocked.

[0034] The bottom of the stirring device 5 is provided with a second discharge port 54. The second discharge port 54 is connected to the filter 6. The stirring device 5 includes a liquid supplement port 55. The liquid supplement port 55 is located on one side of the stirring device 5 close to the second discharge port 54. The third pipeline 713 is connected to the liquid supplement port 55. The third pipeline 713 is installed with a first control valve 7131. The buffer tank 31 is installed with a first liquid level sensor 33. The first liquid level sensor 33 is connected to the first control valve 7131. The first liquid level sensor 33 can sense the liquid level height in the buffer tank 31. When the slurry in the stirring device 5 is too viscous, resulting in difficult discharge and feeding, it will cause the liquid level in the buffer tank 31 to be abnormal, triggering the first liquid level sensor 33. The first liquid level sensor 33 opens the first control valve 7131, and the grinding pump 7 pumps the slurry into the liquid supplement port 55 through the third pipeline 713, promoting the flow of the slurry at the discharge port of the stirring device 5 and preventing blockage in the stirring device 5. When the liquid level in the buffer tank 31 returns to normal, the first control valve 7131 closes, restoring the circulation flow path.

[0035] This embodiment also discloses a method for treating medical residues, which uses the above-mentioned medical hazardous waste residue disposal system, and includes the following steps:

[0036] S1. The material bags are unloaded according to the mixing scheme, the fan 8 is turned on, and the wastewater is fed into the stirring device 5 through the liquid inlet pipe 9. When the liquid level reaches the specified position in the stirring device 5, the liquid inlet is stopped;

[0037] S2, open the grinding pump 7 and the second pipeline 712 in the output pipeline 71, keep the first pipeline 711 and the third pipeline 713 closed, so that the wastewater enters the buffer box 31 of the buffer device 3 through the screw feeder 2, start the pulverizer 4, and the wastewater flows through the pulverizer 4 into the stirring device 5, and a liquid circulation is formed among the buffer box 31, the pulverizer 4, the stirring device 5, and the grinding pump 7;

[0038] S3, start the screw feeder 2, start the agitator, the material bag is grabbed and fed in by the feeding claw 11 of the feeding device 1, and the bag is broken by the bag breaking device 13, and the material is transported to the buffer box 31 by the screw feeder 2, and the material is broken by the shaking device 32 and mixed with waste water and then flows through the pulverizer 4 for pulverization, and the pulverized slurry enters the stirring device 5 for stirring, and the stirred slurry is filtered by the filtering device, and the filtered slurry is transported to the buffer box 31 by the grinding pump 7 for circulation grinding;

[0039] More preferably, when the slurry in the stirring device 5 is too viscous and makes discharging and feeding difficult, the material level in the buffer tank 31 will be abnormal, triggering the first material level sensor 33, the first material level sensor 33 opens the first control valve 7131, and the grinding pump 7 pumps the slurry into the liquid replenishing port 55 through the third pipeline 713, promoting the flow of slurry at the material outlet of the stirring device 5, and preventing blockage in the stirring device 5. When the material level in the buffer tank 31 remains normal, the first control valve 7131 is closed to restore the circulation flow path;

[0040] S4. After 30 minutes of cyclic grinding, sampling is performed at the first pipeline 711 of the output pipeline 71. After the sampling analysis is qualified, the slurry is sent out from the first pipeline 711 to the material transfer tank for standby storage.

[0041] Staffing and capacity calculation: The pharmaceutical hazardous waste residue disposal system of the present invention has a high degree of automation. Only two skilled operators are required for one work shift. One work cycle is divided into three stages: feeding, crushing, grinding and mixing, and discharging. One work cycle is about one hour, and one work shift can be carried out seven times. The work efficiency is high. One loading treatment is calculated as 1.5 tons. One work shift can treat about 10 tons of pharmaceutical hazardous waste and dispose of 12 cubic meters of wastewater at the same time.

[0042] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.

Take out the material bags according to the compatibility plan, turn on the fan (8), and input the wastewater into the stirring device (5) through the liquid inlet pipe (9). Stop the liquid inlet when the liquid level reaches the specified position in the stirring device (5); S2. Turn on the grinding pump (7) and the second pipeline (712) in the output pipeline (71), so that the wastewater enters the buffer tank (31) of the buffer device (3) through the screw feeder (2). Start the pulverizer (4), and the wastewater flows through the pulverizer (4) and enters the stirring device (5). A liquid cycle is formed among the buffer tank (31), the pulverizer (4), the stirring device (5), and the grinding pump (7); S3. Start the screw feeder (2) and the agitator. The material package is grabbed and fed in by the feeding claws (11) of the feeding device (1), unpacked by the unpacking device (13), and the material is transported into the buffer tank (31) by the screw feeder (2). After being dispersed by the material shaking device (32), the material is mixed with wastewater and flows through the pulverizer (4) for pulverization. The pulverized slurry enters the stirring device (5) for stirring. The stirred slurry is filtered by the filtering device, and the filtered slurry is transported to the buffer tank (31) by the grinding pump (7) for circulating grinding; S4. After circulating and grinding for 30 minutes, take a sample at the first pipeline (711) of the output pipeline (71). After the sample analysis is qualified, send the slurry outwards from the first pipeline (711).
