Description

Technical Field

[0001] This utility model relates to the field of waste liquid collection technology, specifically to a waste liquid collection system. Background Technology

[0002] Waste liquid collection systems are devices used to collect and treat waste liquids generated in industrial production, laboratories, or other workplaces. The main function of a waste liquid collection system is to prevent waste liquid leaks and environmental pollution, while facilitating subsequent treatment or recycling. It collects various types of waste liquids, preventing direct discharge into the environment and avoiding waste liquids entering soil, water bodies, or air, thus preventing pollution of ecosystems. Waste liquid collection systems are typically equipped with dedicated containers or tanks to store waste liquids, ensuring safety. Chinese Patent Publication No. CN221045139U discloses a waste liquid collection device, belonging to the field of medical device technology. It includes a protective shell, a receiving base, a collection bucket, and a collection hopper. The collection bucket is fixedly installed on the receiving base. A metal block is fixedly installed on the inner wall of the protective shell, and a magnet is fixedly installed on the inner wall of the receiving base. The protective shell is fixed to the receiving base through the interaction between the metal block and the magnet. A separation component is provided inside the protective shell, including a conical filter screen, a toothed ring, a motor housing, an output motor, a transmission gear, a connecting rod, and a cleaning brush. This waste liquid collection device facilitates centralized treatment of waste liquid by medical personnel. The output motor and rotating cleaning brush clean impurities on the conical filter screen, causing them to fall into the collection bucket for centralized treatment by medical personnel. It offers multiple functions. The aforementioned patent mentions that the waste liquid collection device can clean impurities on the conical filter screen using a rotating cleaning brush, thereby brushing off the impurities and allowing them to fall into the collection box. However, due to the complex composition of impurities in medical waste liquid, including food residue, flocculent secretions, blood clots, etc., small impurities with diameters close to or smaller than the filter screen pores are easily embedded in the pores, while sticky impurities adhere tightly to the edges of the pores due to liquid adsorption. Furthermore, the sweeping motion of the cleaning brush mainly targets larger impurities on the filter screen surface, making it difficult to reach the small or sticky impurities embedded in the pores. As a result, the waste liquid collection system is prone to clogging the conical filter screen after long-term use, leading to a decrease in filtration efficiency. Therefore, we propose a waste liquid collection system. Summary of the Invention

[0003] To address the aforementioned issues, a waste liquid collection system is provided. A drive mechanism causes the filter plate to vibrate up and down, effectively loosening fine and sticky impurities adhering to the mesh, preventing long-term accumulation of impurities in the filter. Simultaneously, a transmission mechanism drives a cleaning component to clean impurities on the surface of the filter plate, removing fine and sticky impurities embedded in the mesh or adhering to the mesh edges. This solves the technical problem that fine or sticky impurities easily embed or adhere to the conical filter mesh, leading to easy clogging and decreased filtration efficiency of the waste liquid collection system over long-term use.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1-4 As shown, a waste liquid collection system includes a waste liquid collection device 1, a waste liquid tank 11, and a filter plate 2 on the inner side of the waste liquid tank 11. A cleaning component 21 is rotatably mounted on the filter plate 2. A collection box 22 is fixed on the waste liquid tank 11, and a cover plate 23 is mounted on the upper side of the collection box 22. A drive mechanism is provided on the filter plate 2 for driving the filter plate 2 to move up and down. A transmission mechanism is provided between the cleaning component 21 and the drive mechanism for driving the cleaning component 21 to rotate. A displacement mechanism is provided between the cover plate 23 and the waste liquid tank 11 for driving the cover plate 23 to move vertically.

[0025] Specifically, the cleaning component 21 uses a soft brush to avoid damaging the surface of the filter plate 2, and the cleaning component 21 is kept in a compressed state with the filter plate 2. A mesh plate 2201 is fixedly installed on the side of the waste liquid tank 11 near the collection box 22. The mesh plate 2201 is used to help the waste liquid in the collection box 22 return to the interior of the waste liquid tank 11.

[0026] When the waste liquid collection system is put into use, waste liquid is injected into the waste liquid tank 11, and the filter plate 2 filters the waste liquid. At this time, the filter plate 2 is driven to vibrate up and down by the drive mechanism, and at the same time, the power component 24 drives the cleaning component 21 to rotate along the surface of the filter plate 2 through the transmission mechanism. The cleaning component 21 is preferably a brush that does not damage the filter plate 2. It is kept in a state of compression with the filter plate 2 and can clean impurities on the surface of the filter plate 2.

[0027] The up-and-down vibration of filter plate 2 loosens surface impurities, effectively preventing small or sticky impurities from embedding into the mesh of filter plate 2, reducing the risk of clogging. Simultaneously, the cleaning component 21 removes the loosened impurities, preventing them from re-adhering to the mesh of filter plate 2, ensuring unobstructed filtration channels and improving impurity removal efficiency. During the up-and-down vibration of filter plate 2, the sweeping motion of the cleaning component 21 quickly discharges impurities into collection box 22, preventing impurities from remaining in filter plate 2 for too long, ensuring a fast and efficient cleaning process. Waste liquid carried by impurities in collection box 22 flows back to waste liquid tank 11 through mesh plate 2201.

[0028] When it is necessary to clean the impurities in the collection box 22, the cover plate 23 is driven to move upward and separate from the collection box 22 by the displacement mechanism, so that the cover plate 23 can quickly move away from the collection box 22, which is convenient for the staff to operate and reduces the cleaning time. After the cover plate 23 moves upward, the staff can fully contact all the impurities in the collection box 22 to ensure thorough cleaning and avoid cleaning dead corners.

[0029] See Figures 2-4 , Figure 5 , Figure 7 and Figure 8As shown, the driving mechanism includes a power component 24, a guide assembly, and a reset assembly; the power component 24 is fixedly connected to the waste liquid tank 11; the guide assembly is disposed between the filter plate 2 and the waste liquid tank 11, and is used to assist the filter plate 2 in vertical displacement inside the waste liquid tank 11; the reset assembly is disposed between the filter plate 2 and the guide assembly, and is used to reset the filter plate 2 to its initial position; the guide assembly includes a pusher 25, a support rod 26, and a support plate 27; the pusher 25 is rotatably disposed on the waste liquid tank 11, and one end of the pusher 25 is fixedly connected to the output end of the power component 24; the support rod 26 is disposed between the filter plate 2 and the pusher 25; the support plate 27 is fixedly connected to the waste liquid tank 11, and the support rod 26 slides through the support plate 27; the reset assembly includes two first elastic reset members 28 and two first connecting covers 28. 9. A second elastic reset member 210 and a second connecting cover 211; two first elastic reset members 28 are respectively sleeved on both ends of the support rod 26, and the first elastic reset members 28 are fixedly connected to the filter plate 2, the support rod 26 and the support plate 27 respectively; two first connecting covers 29 are respectively sleeved on the outside of the two first elastic reset members 28, and the first connecting covers 29 are fixedly connected to the filter plate 2, the support rod 26 and the support plate 27 respectively; the second elastic reset member 210 is disposed between the waste liquid tank 11 and the filter plate 2, and one end of the second elastic reset member 210 is fixedly connected to the waste liquid tank 11; the second connecting cover 211 is disposed on the outside of the second elastic reset member 210, and the second connecting cover 211 is fixedly connected to the waste liquid tank 11, and the end of the second elastic reset member 210 away from the waste liquid tank 11 is fixedly connected to the second connecting cover 211.

[0030] Specifically, the power component 24 is preferably a motor. The first elastic reset component 28 and the second elastic reset component 210 are preferably springs. The first connecting cover 29 is preferably a deformable folded bellows. The second connecting cover 211 is preferably a deformable rubber cover.

[0031] When waste liquid is injected into waste liquid tank 11, filter plate 2 filters the waste liquid; at the same time, power component 24 is activated, and the output end of power component 24 drives push frame 25 to rotate. Push frame 25 squeezes the lower end of support rod 26 and pushes support rod 26 upward. First elastic reset component 28 is preferably a spring, and first connecting cover 29 is preferably a deformable foldable corrugated tube. During the upward movement of support rod 26, the first elastic reset component 28 and the first connecting cover 29 contract and squeeze, so that support rod 26 generates an upward force to push filter plate 2; second connecting cover 211 is preferably a deformable rubber cover to ensure that filter plate 2 can move upward accordingly.

[0032] When the pusher 25 continues to rotate until it disengages from the support rod 26, the second elastic reset member 210 is preferably a spring that, together with the first elastic reset member 28, drives the filter plate 2 to reset. Through the continuous rotation of the pusher 25, the filter plate 2 vibrates up and down, which can prevent impurities from accumulating on the surface of the filter plate 2 for a long time, and allow the impurities to be removed from the filter plate 2 through periodic vibration, effectively preventing the filter plate 2 from clogging.

[0033] See Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the transmission mechanism includes a bevel gear assembly 212 and a telescopic assembly; the bevel gear assembly 212 is rotatably mounted on the waste liquid tank 11, and the working end of the bevel gear assembly 212 is fixedly connected to the push frame 25; the telescopic assembly is disposed between the cleaning component 21 and the bevel gear assembly 212, and the telescopic assembly is used to cooperate with the power component 24 to drive the cleaning component 21 to rotate when the filter plate 2 moves; the telescopic assembly includes a slide rod 213 and a connecting pipe 214; the slide rod 213 is fixedly connected to the working end of the bevel gear assembly 212 away from the push frame 25; the connecting pipe 214 is slidably engaged with the end of the slide rod 213 away from the bevel gear assembly 212, and the upper end of the connecting pipe 214 is fixedly connected to the cleaning component 21.

[0034] Specifically, the bevel gear assembly 212 consists of meshing bevel gears. The slide rod 213 and the connecting pipe 214 form a sliding guide pair. The slide rod 213 has a rectangular cross-sectional shape. A third connecting cover 21401 is fitted onto the lower end of the slide rod 213, and both ends of the third connecting cover 21401 are fixedly connected to the slide rod 213 and the connecting pipe 214, respectively. The third connecting cover 21401 is preferably a deformable folded corrugated pipe.

[0035] When the power component 24 drives the pusher 25 to rotate, causing the filter plate 2 to vibrate up and down, the third connecting cover 21401, preferably a deformable folded corrugated pipe, causes the filter plate 2 to slide along the outside of the slide rod 213 via the connecting pipe 214. The sliding guide pair formed by the slide rod 213 and the connecting pipe 214 restricts the swaying and offset of the slide rod 213 inside the connecting pipe 214, ensuring that the up and down vibration of the filter plate 2 is not disturbed.

[0036] Simultaneously, the working end of the power component 24 drives the working end of the bevel gear assembly 212 to rotate. Since the bevel gear assembly 212 is composed of meshing bevel gears, it can drive the slide rod 213 to rotate synchronously. The rectangular cross-section structure of the slide rod 213 allows it to drive the cleaning component 21 to rotate through the connecting pipe 214, ensuring that the cleaning component 21 maintains a stable rotational state during the vibration of the filter plate 2, thereby achieving continuous cleaning of the filter plate 2, timely removing impurities, deposits, and adhering substances from the surface of the filter plate 2, and enhancing the loosening and removal effect of impurities.

[0037] See Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the displacement mechanism includes a handwheel 215, a slider 216, a groove 217, and a screw 218. The handwheel 215 is positioned above the cover plate 23. The slider 216 is fixedly connected to the cover plate 23. The groove 217 is located on the side of the waste liquid tank 11 near the slider 216, and the groove 217 and the slider 216 are in sliding engagement. The screw 218 is rotatably mounted on the groove 217 and is threadedly connected to the slider 216. The displacement mechanism also includes a transmission assembly, which is used to synchronously drive the screw 218 to rotate in conjunction with the handwheel 215. The transmission assembly includes a geared disc 219 and a geared ring 220. The geared disc 219 is rotatably mounted on the waste liquid tank 11 and is fixedly connected to the screw 218. The geared ring 220 is rotatably mounted on the waste liquid tank 11, meshes with the geared disc 219, and is fixedly connected to the handwheel 215.

[0038] Specifically, a deformable rubber pad is connected to the lower side of the cover plate 23. The slider 216 and the groove 217 form a sliding guide pair.

[0039] When it is necessary to clean the impurities in the collection box 22, rotate the handwheel 215, which drives the gear ring 220 to rotate. Through the meshing and engagement of the gear ring 220 with the gear disc 219, the gear ring 220 drives each gear disc 219 to rotate synchronously, thereby driving each screw 218 to rotate.

[0040] The sliding guide pair formed by the slider 216 and the groove 217 restricts the slider 216 from rotating synchronously with the screw 218. The screw 218 is threadedly connected to the slider 216, causing the slider 216 to move the cover plate 23 upward. The cover plate 23 simultaneously moves the rubber pad upward and disengages from the squeezing contact with the collection box 22, thus releasing the seal of the collection box 22. At this time, the staff can quickly open the cover plate 23 to clean the inside of the collection box 22, reducing cleaning time, ensuring thorough cleaning, and avoiding omissions in cleaning dead corners.

[0041] Working principle: When the waste liquid collection system is put into use, waste liquid is injected into the waste liquid tank 11. The filter plate 2 filters the waste liquid and activates the power component 24. The power component 24 drives the filter plate 2 to vibrate up and down. At the same time, the power component 24 drives the cleaning component 21 to rotate along the surface of the filter plate 2. The up and down vibration of the filter plate 2 can loosen the surface impurities, effectively preventing small or sticky impurities from embedding into the mesh of the filter plate 2, reducing the risk of clogging. The cleaning component 21 simultaneously removes the loosened impurities, preventing impurities from re-attaching to the mesh of the filter plate 2, ensuring that the filtration channel is unobstructed, improving the impurity removal efficiency, and preventing small or sticky impurities from easily embedding or attaching to the mesh of the filter plate 2.

[0042] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
