However, in actual use, the patent still has the problem of incomplete sludge collection and poor collection efficiency.

[0004] After the existing medical waste liquid treatment device has been in operation for a period of time, its filter screen will inevitably be clogged by dirt. The traditional response is to shut down for cleaning, which will affect the treatment efficiency. Although some advanced waste liquid treatment devices adopt a double-barrel switching design, allowing cleaning work to be performed in the interval between switching the use of the cylinder, this design has significant disadvantages. Specifically, the double-barrel structure causes one of the cylinders to be idle most of the time, making it difficult to fully utilize and reasonably plan, resulting in a serious waste of resources.

The inclined design on one side of the scraper enables it to continuously clean the filter cartridge. During the low-speed rotation of the filter cartridge, the device not only uses the centrifugal effect to treat the waste liquid, but also reduces the impurities adhering to the surface of the filter cartridge by continuously shaking the filter cartridge. This shaking method not only helps to improve the efficiency of waste liquid treatment, but also cooperates with the continuous cleaning process of the scraper to effectively avoid the blockage of the filter cartridge.

[0018] 3. The present invention also designs movable components, adjustment components and cleaning components. When the motor runs in reverse at high speed, it not only drives the filter cartridge to rotate, but also makes the pulley above the filter cartridge contact the vertical surface of the limit block. This contact enables the movable disk to synchronously drive the collecting box to rotate at high speed during the rotation process. At the same time, the waste liquid inside the filter cartridge is discharged faster due to the accelerated rotation. Therefore, while collecting and processing impurities in the waste liquid, the present invention can still maintain the processing efficiency of the waste liquid, effectively avoiding the reduction of the processing effect due to the blockage of the filter cartridge by the waste liquid. In addition, the present invention does not require shutdown for cleaning, thereby reducing the overall maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1 To Attachment Fig. 9 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, not to limit the scope of the present invention.

[0022] A medical nursing waste liquid treatment device comprises a shell mechanism 1 and a filtering mechanism 2. The shell mechanism 1 comprises an outer tube 11, a mounting buckle 12, a top cover 13, a valve 14, a liquid injection tube 15, a support leg 16 and a liquid discharge valve 17. The mounting buckle 12 is arranged on the outer wall of the outer tube 11, the top cover 13 is located above the outer tube 11, the valve 14 is connected to the top cover 13, the liquid injection tube 15 is connected to the valve 14, the support leg 16 is arranged on the outer wall of the outer tube 11, and the liquid discharge valve 17 is connected to the outer tube 11.

[0023] The filter mechanism 2 includes a motor 21, a drive assembly 22, a base plate 23, a filter assembly 24, an adjustment assembly 25, a collection assembly 26, a cleaning assembly 27, a movable assembly 28 and a one-way rotating assembly 29. The drive assembly 22 is connected to the motor 21, the base plate 23 is located outside the drive assembly 22, the filter assembly 24 is connected to the base plate 23, the movable assembly 28 is connected to the adjustment assembly 25, the one-way rotating assembly 29 is connected to the movable assembly 28, the adjustment assembly 25 is located on the top of the filter assembly 24, the collection assembly 26 is connected to the bottom of the movable assembly 28, and the cleaning assembly 27 is connected to the collection assembly 26.

[0024] The present invention switches the mode by manual control or timed switching. When switched to the energy-saving waste liquid treatment mode, the motor 21 runs at a low speed, and the motor 21 drives the filter assembly 24 to rotate through the driving assembly 22. The filter assembly 24 rotates under the movable assembly 28 through the adjusting assembly 25, so that the adjusting assembly 25 drives the filter assembly 24 to continuously shake. At this time, the one-way rotating assembly 29 limits the movable assembly 28 to prevent the movable assembly 28 from rotating. Under the rotation and push of the driving assembly 22, the liquid inside the outer cylinder 11 generates centrifugal force, and the liquid flows from the inside of the filter assembly 24 to the outside of the filter assembly 24, completing the filtering process of the liquid.

[0025] When switched to the accelerated waste liquid treatment mode, the motor 21 runs in reverse at high speed. The motor 21 drives the filter component 24 to rotate through the driving component 22. The filter component 24 drives the movable component 28 to rotate through the adjusting component 25, so that the impurities accumulated in the cleaning component 27 are driven by the cleaning component 27 to move upward to the collecting component 26 under the action of centrifugal force.

[0026] When the motor 21 is running at a low speed, the movable component 28 can make the filter component 24 continue to shake during the rotation process, thereby ensuring the filtering effect of the filter component 24 on the waste liquid; when the motor 21 is running at a high speed, the liquid centrifugal force generated by the rotation can also ensure the effect of waste liquid treatment. At the same time, the inner wall and the outer wall of the filter component 24 are matched with the cleaning component 27, which further improves the quality of waste liquid treatment. Compared with the existing waste liquid treatment device, the present invention can complete the waste liquid treatment without the need for double-barrel cooperation, and reduces the difficulty of use, thereby saving resources and reducing maintenance costs.

[0030] By designing four cleaning components 27 on the inner wall and outer wall of the filter cartridge 244 respectively, it is ensured that the inner wall and outer wall of the filter cartridge 244 are fully cleaned, thereby ensuring the cleaning effect of the device.

[0031] As another embodiment of the present invention, the adjustment component 25 includes a positioning block 251, a push rod 252 is fixedly connected to the top of the positioning block 251, a pulley 253 is fixedly connected to the top of the push rod 252, the positioning block 251 is fixedly connected to the top of the filter cartridge 244, and the pulley 253 is slidably connected in the movable component 28.

[0032] The collecting assembly 26 includes a collecting box 261, a connecting rod 262 is fixedly connected to the top of the collecting box 261, a reinforcing plate 263 is fixedly connected inside the collecting box 261, a second elastic telescopic rod 264 is fixedly connected to one side of the reinforcing plate 263, the other end of the second elastic telescopic rod 264 is fixedly connected to a sealing plate 266 via a reinforcing rib 265, a plurality of counterweight blocks 267 are fixedly connected to the top of the sealing plate 266, a feed port 268 is provided at the bottom of the collecting box 261, the sealing plate 266 is clamped above the feed port 268, the collecting box 261 is fixedly connected to the bottom of the movable assembly 28 via the connecting rod 262, and the bottom of the collecting box 261 is fixedly connected to the top of the cleaning assembly 27.

[0033] The cleaning assembly 27 outside the filter cartridge 244 pushes the collected waste to the feed port 268 ; the counterweight block 267 ensures that under high-speed rotation, the sealing plate 266 will rotate under the action of the counterweight block 267 , thereby ensuring that the waste enters the collection box 261 .

[0034] As another embodiment of the present invention, the cleaning assembly 27 includes a scraper 271, and the scraper 271 adopts a spiral design. A guide groove 272 is provided on one side of the scraper 271; the other side of the scraper 271 adopts an inclined design, that is, it forms an angle with the filter cartridge 244. The upper part of the scraper 271 is fixedly connected to the lower part of the collection box 261, and the scraper 271 overlaps the filter cartridge 244. The position of the guide groove 272 on the scraper 271 corresponds to the position of the feed port 268.

[0035] The spiral design of the scraper 271 can ensure that the material moves up along the guide groove 272 when pushed by the centrifugal force. The scraper 271 adopts an inclined design to increase the contact area with the liquid, ensuring that the scraper 271 can effectively clean the filter cartridge 244, and the scraped waste enters the collection box 261 along the guide groove 272, thereby completing the waste recovery.

[0036] The movable assembly 28 includes a movable disk 281, a plurality of ratchet blocks 282 are fixedly connected to the upper part of the movable disk 281, and the plurality of ratchet blocks 282 are arranged in an annular manner and equidistantly above the movable disk 281, and a plurality of stop blocks 283 are fixedly connected to the lower part of the movable disk 281, and the plurality of stop blocks 283 are arranged in an annular manner and equidistantly. The two sides of the stop block 283 are respectively arranged as a vertical surface and an arc surface, the upper part of the ratchet block 282 overlaps with the one-way rotating assembly 29, the collecting box 261 is fixedly connected to the lower part of the movable disk 281 through the connecting rod 262, and the pulley 253 overlaps with the stop block 283.

[0037] The one-way rotating assembly 29 includes a bearing 291, a rotating shaft 292 is sleeved in the bearing 291, one end of the rotating shaft 292 is fixedly connected to a ratchet 293, a coil spring 294 is sleeved on the outer wall of the rotating shaft 292, and the two ends of the coil spring 294 are respectively fixedly connected to the bearing 291 and the rotating shaft 292, an extension block 295 is sleeved on the outer wall of the bearing 291, and the extension block 295 is fixedly connected to a positioning rod 296, and a stopper 297 is fixedly connected to the other side of the positioning rod 296, one side of the stopper 297 overlaps with the ratchet 293, the bearing 291 is clamped on the inner wall of the outer cylinder 11, and the ratchet 293 overlaps with the ratchet block 282. Through the matching design of the ratchet 293 and the stopper 297, the movable disk 281 rotating in the opposite direction is restricted by the ratchet 293 and the stopper 297, so as to prevent the ratchet 293 from being moved by the ratchet block 282 above the movable disk 281, causing the movable disk 281 to rotate in the opposite direction.

[0038] Working principle: waste liquid enters the housing mechanism 1 through the injection pipe 15, and the motor 21 is started. The motor 21 runs forward at a low speed, so that the whole enters the energy-saving waste liquid treatment mode; when it is necessary to treat the pollutants, the motor 21 runs reversely at a high speed, so that the whole enters the accelerated waste liquid treatment mode, so that the internal cleaning can be carried out simultaneously when the waste liquid treatment is accelerated. The whole can switch the forward low-speed operation and reverse high-speed operation of the motor 21 by timed automatic switching operation mode or manual switching mode.

[0039] Specifically, when the motor 21 runs forward at a low speed, the motor 21 will synchronously drive the sealing cylinder 241 to rotate through the driving shaft 221, the fixing sleeve 222 and the mounting frame 245; since the sealing cylinder 241 is connected to the filter cylinder 244 through the first elastic telescopic rod 242 and the fixing block 243, the filter cylinder 244 will also rotate synchronously. When the filter cylinder 244 rotates, the pulley 253 will slide under a plurality of limit blocks 283 through the push rod 252; when the pulley 253 passes through the arc surface of the limit block 283, the filter cylinder 244 is compressed and moves downward as a whole; when the pulley 253 passes through the vertical surface of the limit block 283, the first elastic telescopic rod 242 pushes the filter cylinder 244 to reset, and so on.

[0040] In the above process, the movable disk 281 is positioned by the ratchet block 282 and the ratchet 293, so that the scraper 271 is in place, and the filter cartridge 244 is continuously cleaned by the inclined surface of one side of the scraper 271, so that the filter cartridge 244 can treat the waste liquid by centrifugal action when rotating at a low speed; at the same time, the filter cartridge 244 itself will be in a state of continuous shaking. The shaking of the filter cartridge 244 can reduce the impurities adhering to the surface of the filter cartridge 244, and can also improve the treatment efficiency of the waste liquid, and can cooperate with the scraper 271 to continuously clean the filter cartridge 244 to avoid the blockage of the filter cartridge 244.

[0041] When the motor 21 runs in reverse at high speed, the motor 21 drives the filter cartridge 244 to rotate, and the pulley 253 above the filter cartridge 244 contacts the vertical surface of the limit block 283. At this time, the pulley 253 drives the movable disk 281 to rotate in the opposite direction, and the ratchet block 282 and the ratchet 293 are disengaged, so that the movable disk 281 synchronously drives the collection box 261 to rotate at high speed during the rotation process. The centrifugal force generated by the high-speed rotation can make the counterweight block 267 drive the sealing plate 266 to rotate in the collection box 261. At this time, the scraper 271 collects impurities through the guide groove 272 and moves the impurities upward along the guide groove 272. The impurities eventually enter the collection box 261 along the feed port 268. Since the filter cartridge 244 is in a high-speed rotation state, the waste liquid inside the filter cartridge 244 will be discharged faster, thereby ensuring the treatment efficiency of the waste liquid and avoiding the blockage of the filter cartridge 244, which leads to a reduction in the waste liquid treatment effect.
