Description

Technical Field

[0001] The present invention relates to the technical field of hazardous waste recycling, and in particular to a wastewater treatment device based on a hazardous waste disposal box. Background Art

[0002] Hazardous waste disposal bins are loading devices used for the collection, transfer, and temporary storage of solid hazardous waste. They are widely used in medical institutions, chemical companies, scientific research laboratories, and other fields. During the waste transfer process, the bins are responsible for isolating, preventing leaks, and protecting solid hazardous waste during transportation. Conventional hazardous waste disposal bins are relatively closed structures, relying primarily on manual opening, loading, and sealing operations. Loading and unloading are handled by robotic arms or forklifts to ensure the safety and compliance of waste during transfer.

[0003] However, existing hazardous waste disposal bins often experience waste liquid retention or leakage during practical use. This is particularly true for chemical waste, liquid hazardous waste, or wet solid waste, which can easily accumulate at the bottom of the bin. Leakage of such waste not only pollutes the surrounding environment but also increases the burden of manual collection and cleaning for operators, posing a significant safety hazard. Currently, most hazardous waste disposal bins lack integrated, effective waste liquid treatment mechanisms. While simple filter screens can separate waste liquids, they lack the ability to dynamically adjust the filter screen seal to ensure a dry and airtight interior. Furthermore, the presence of microscopic impurities, components, or grit in the waste can clog the waste liquid channel and hinder separate collection, requiring manual sorting and increasing labor costs. The waste liquid collection area, which contains hazardous waste liquids, requires regular cleaning. This makes it difficult to maintain proper isolation and cleaning procedures to prevent the flushing fluid from soaking the waste within the bin (causing secondary contamination or flushing the waste liquid, contaminating a larger area). Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a wastewater treatment device based on a hazardous waste disposal box.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A wastewater treatment device based on a hazardous waste disposal box includes a treatment box body, which is a fully enclosed structure, an opening and closing door plate is provided at one end of the treatment box body, a drainage trough is provided at the bottom of the inner cavity of the treatment box body, a plurality of liquid conduction tubes are arranged in the drainage trough, a plurality of liquid conduction holes penetrating the inner cavity of the liquid conduction tubes are provided on the side walls of the liquid conduction tubes along the axis, a waste liquid port connected to the liquid conduction tubes is provided at one end of the drainage trough, a driving assembly for controlling the rotation of the plurality of liquid conduction tubes is also installed in the drainage trough, the drainage trough is covered with a support frame plate, the liquid conduction tubes abut against the support frame plate, and a plurality of filtrate holes corresponding to the liquid conduction holes are provided on the support frame plate.

[0006] Furthermore, several of the catheter tubes are arranged at equal intervals along the short sides of the drainage trough. Connecting conduits are provided at both ends of the catheter tubes, and the catheter tubes are connected to the connecting conduits via rotary joints. A gap is reserved between adjacent catheter tubes. Both ends of the catheter tubes are provided with rotary joints, and are connected to the sidewalls of the connecting conduits via the rotary joints. While the catheter tubes rotate under the drive assembly, they maintain sealed communication with the connecting conduits, ensuring that waste liquid or flushing fluid can flow continuously and leak-free between the catheter tubes and the external port.

[0007] Furthermore, a flushing port and a sediment discharge port are provided at both ends of the drainage trough, respectively. The sediment discharge port is provided on the same side as the waste liquid port, and the connecting conduits at both ends of the liquid guide tube are connected to the flushing port and the waste liquid port, respectively. The flushing port is used to introduce flushing liquid to reversely flush the inner wall and liquid guide hole of the liquid guide tube, and the pure waste liquid is collected through the waste liquid container externally connected to the waste liquid port. The sediment discharge port is used to collect and discharge solid particulate impurities collected in the second filter screen. By rotating the liquid guide tube 180°, the collection trough of the second filter screen faces downward, and the solid particulate impurities are poured out to the bottom of the slag separator, and then discharged from the sediment discharge port and collected through the external waste container.

[0008] Furthermore, a one-way valve is provided on the connecting conduit connected to the flushing port. The one-way valve directs the flow of liquid from the flushing port to the liquid conduit. During waste liquid collection, the liquid conduit's through-hole faces upward and communicates with the filtrate hole. Waste liquid then enters the liquid conduit through the filtrate hole and the liquid conduit through-hole. Due to the one-way valve, waste liquid can only exit through the waste liquid port. This prevents waste liquid from entering the flushing pipeline or contaminating the flushing liquid source, ensuring safety and isolation during the cleaning process.

[0009] Furthermore, the bottom of the drainage trough is provided with multiple partitions, with multiple diversion channels formed between the multiple partitions. The multiple diversion channels correspond vertically to the liquid guide tubes, and the sediment discharge outlet and the diversion channels are located on the same horizontal plane. The partitions divide the bottom of the drainage trough into multiple independent diversion channels, each corresponding to a liquid guide tube. When the liquid guide tube rotates, solid particulate impurities collected in the second filter screen fall into the diversion channels under the influence of gravity and the flushing of the flushing liquid. These solid particulate impurities are then pushed to the sediment discharge outlet for discharge under the continuous flushing of the water flow, achieving separation and targeted collection of impurities and waste liquid.

[0010] Furthermore, the bottom of the drainage trough is tilted, with the level of the partition plate on the flushing port side higher than the level of the partition plate on the sediment discharge port side. During sludge discharge, solid particles that fall into the diversion channel are more likely to slide towards the lower sediment discharge port under the influence of gravity or flushing liquid, reducing the risk of clogging. This also prevents the accumulation of flushing liquid at the bottom of the trough, improving cleaning effectiveness.

[0011] Furthermore, a slag separator is provided within the drainage trough. The separator is positioned below the liquid guide tube and is in close contact with the tube. The separator is provided with drainage holes corresponding to the drainage holes. The separator is used to isolate solid particulate impurities below the separator. Under the flushing of the flushing liquid, a closed "liquid channel" is formed, allowing the flushing liquid mixed with solid particulate impurities to be smoothly guided to the sediment discharge outlet.

[0012] Furthermore, several covering plates are provided between the support frame plate and the slag separator plate. The covering plates are of an arc-shaped structure, and the covering plates are fitted with the side walls of any liquid guide tube. Two covering plates are provided between any two liquid guide tubes, the convex surfaces of the two covering plates are connected, and the concave surfaces of the covering plates are fitted with the sides of the liquid guide tubes. Its function is that during the rotation of the liquid guide tube, the solid particle impurities in the second filter screen will not fall out, but will be discharged through the drainage through hole after the liquid guide hole and the drainage through hole are connected. In addition, when the liquid guide tube rotates, the edge of the covering plate will scrape the tube wall, peeling off the viscous waste liquid, tiny particles or substances that may clog the through hole attached to the outer surface of the liquid guide tube. The scraped material is guided to fall into the drainage through hole below, and finally flows to the sediment discharge outlet.

[0013] Furthermore, a first filter is provided on the filtrate hole, and a second filter with a U-shaped structure is provided on the liquid guiding hole. The second filter is located in the inner cavity of the liquid guiding tube and covers the liquid guiding hole. The aperture of the first filter is larger than that of the second filter. The first filter mainly intercepts larger solid waste or debris to prevent them from entering the interior of the liquid guiding tube. The second filter has a smaller aperture and collects micro impurities, parts or gravel that pass through the first filter to prevent them from entering the inner cavity of the liquid guiding tube and causing blockage, and collects these solid particle impurities separately by introducing them into the diversion channel. The second filter with a U-shaped structure design can not only increase the filtration area and reduce the probability of single-point blockage, but also when the flushing liquid is backflushed, the flushing water flow can flush the particles stuck in the U-shaped mesh back into the second filter, and then fall into the diversion channel through the drainage hole.

[0014] Furthermore, the drive assembly includes a motor and a transmission belt. The motor is fixedly mounted at one end of the drainage trough, and the transmission belt is sleeved on one end of the catheter tube. The inner ring of the transmission belt is transmission-connected to several catheter tubes, and the outer ring of the transmission belt is transmission-connected to the output end of the motor. The inner and outer rings of the transmission belt are both provided with toothed belts. The inner ring of the transmission belt is meshed with the end of the catheter tube via a raised pulley to ensure that all catheter tubes rotate at the same angle and speed. The outer ring of the transmission belt is meshed with the output end of the motor. By setting the control system on the motor, the number of rotations of the catheter tube is half a circle under a single operation, that is, the catheter through hole rotates from vertically upward to vertically downward, and then from vertically downward to vertically upward, thereby realizing the functions of sealing, draining and cleaning.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention controls the rotation of the liquid guide tube through a driving assembly to achieve dynamic connection or closure of the liquid guide hole and the filtrate hole, thereby enabling the liquid guide tube to flexibly switch between the three modes of drainage, flushing, and sealing, ensuring that the treatment box remains dry and sealed when not draining liquid; 2. The present invention provides a built-in U-shaped second filter at the liquid guide hole on the side wall of the liquid guide tube, and provides a partition plate and a diversion channel at the bottom of the drainage trough. Together with the sediment discharge port, this can separate micro impurities, parts or gravel from the waste liquid and concentrate them in the diversion channel. Finally, they are separately collected and discharged through the sediment discharge port, thus achieving the classified treatment of solid particles and waste liquid. 3. The present invention installs a one-way valve on the connecting conduit connected to the flushing port, adopts an inclined structure at the bottom of the drainage trough and adds a slag separator. When cleaning the liquid guide pipe, the flushing liquid can be introduced into the drainage trough through the filtrate hole without flowing back into the processing box, thereby avoiding secondary contamination of solid waste in the box during the flushing process.

DETAILED DESCRIPTION

[0017] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0018] Example 1, as Figures 1-6 As shown, the present invention discloses a wastewater treatment device based on a hazardous waste disposal box, including a treatment box body 1, which is a fully enclosed structure, and an opening and closing door panel 2 is provided at one end of the treatment box body 1, and a drainage groove 3 is provided at the bottom of the inner cavity of the treatment box body 1, and several liquid conduction tubes 4 are arranged in the drainage groove 3, and the side walls of the liquid conduction tubes 4 are provided with several liquid conduction holes 5 that pass through the inner cavity of the liquid conduction tubes 4 along the axis. A waste liquid port 6 connected to the liquid conduction tube 4 is provided at one end of the drainage groove 3, and a driving component for controlling the rotation of several liquid conduction tubes 4 is also installed in the drainage groove 3, and the drainage groove 3 is covered with a support frame plate 7, and the liquid conduction tubes 4 are abutted against the support frame plate 7, and the support frame plate 7 is provided with several filtrate holes 8 corresponding to the liquid conduction holes 5.

[0019] Several of the aforementioned liquid conduits 4 are arranged at equal intervals along the short sides of the drainage trough 3. Connecting conduits 9 are provided at both ends of each of the liquid conduits 4, and each of the liquid conduits 4 communicates with the connecting conduits 9 via a rotary joint. Specifically, a gap is reserved between adjacent liquid conduits 4. Each of the liquid conduits 4 is provided with a rotary joint, and is connected to the sidewalls of the connecting conduits 9 via the rotary joint. While the liquid conduits 4 rotate under the drive assembly, they maintain a sealed connection with the connecting conduits 9, ensuring that waste liquid or flushing fluid can flow continuously and leak-free between the liquid conduits 4 and the external ports (waste port 6 and flushing port 10).

[0020] A flushing port 10 and a sediment discharge port 11 are provided at both ends of the drainage trough 3, respectively. The sediment discharge port 11 is provided on the same side as the waste liquid port 6, and the connecting conduits 9 at both ends of the liquid guide tube 4 are connected to the flushing port 10 and the waste liquid port 6, respectively. Specifically, the flushing port 10 is used to introduce flushing liquid to reversely flush the inner wall of the liquid guide tube 4 and the liquid guide hole 5, and to collect pure waste liquid through the waste liquid container externally connected to the waste liquid port 6. The sediment discharge port 11 is used to collect and discharge solid particulate impurities (micro impurities, parts or gravel) collected in the second filter screen 16. By rotating the liquid guide tube 4 180°, with the collection slot of the second filter screen 16 facing downward, the solid particulate impurities are poured out to the bottom of the slag separator 13, and then discharged from the sediment discharge port 11 and collected through the external waste container.

[0021] The connecting conduit 9, connected to the flushing port 10, is equipped with a one-way valve. The one-way valve directs the flow from the flushing port 10 to the liquid conduit 4. Specifically, during waste liquid collection, the liquid conduit 5 of the liquid conduit 4 faces upward and communicates with the filtrate hole 8. The waste liquid then enters the liquid conduit 4 through the filtrate hole 8 and the liquid conduit 5. Due to the one-way valve, the waste liquid can only exit through the waste liquid port 6. This prevents waste liquid from entering the flushing pipeline or contaminating the flushing liquid source, ensuring safety and isolation during the cleaning process.

[0022] The bottom of the drainage trough 3 is provided with a plurality of partition plates 12, and a plurality of diversion channels are formed between the plurality of partition plates 12. The plurality of diversion channels correspond vertically to the liquid guide tube 4, and the sediment discharge port 11 and the diversion channels are located on the same horizontal plane. Specifically, the partition plates 12 divide the bottom of the drainage trough 3 into a plurality of independent diversion channels, each of which corresponds to a liquid guide tube 4. When the liquid guide tube 4 rotates, the solid particle impurities collected in the second filter screen 16 fall into the diversion channel under the influence of gravity and the flushing of the flushing liquid, so that these solid particle impurities are pushed to the sediment discharge port 11 for discharge under the continuous flushing of the water flow, thereby achieving separation and directional collection of impurities and waste liquid. Preferably, since the bottom area of ​​the drainage trough 3 is large, if the diversion channel is not provided, some solid particle impurities may accumulate at the bottom of the drainage trough 3 and cannot be introduced into the sediment discharge port 11 under the flushing of the flushing liquid. The partition plate 12 can be provided to shorten the channel area, thereby increasing the impact force of the flushing liquid on the accumulated solid particle impurities, thereby smoothly flushing the solid particle impurities and guiding them into the sediment discharge port 11.

[0023] The bottom of the drainage trough 3 is tilted, with the partition plate 12 positioned at a higher level on the flushing port 10 side than on the sediment discharge port 11 side. Specifically, during slag discharge, solid particles that fall into the diversion channel are more likely to slide toward the lower sediment discharge port 11 under the influence of gravity or flushing fluid, reducing the risk of clogging. This also prevents the accumulation of flushing fluid at the bottom of the trough, improving cleaning effectiveness.

[0024] A slag separator 13 is also provided in the drainage trough 3. The slag separator 13 is located below the liquid guide tube 4 and is closely attached to the liquid guide tube 4. The slag separator 13 is provided with drainage holes 14 corresponding to the liquid guide holes 5. Specifically, the slag separator 13 is used to isolate solid particulate impurities below the slag separator 13. Under the flushing of the flushing liquid, a closed "liquid guide channel" is formed, so that the flushing liquid mixed with solid particulate impurities can be smoothly guided to the sediment discharge port 11. Several arc-shaped cover plates 15 are positioned between the support frame 7 and the slag separator 13. These cover plates 15 are designed to mate with the sidewalls of any liquid conduit 4. Specifically, two cover plates 15 are positioned between any two liquid conduits 4. The convex surfaces of the two cover plates 15 are connected, and the concave surfaces of the cover plates 15 mate with the sides of the liquid conduits 4. This prevents solid particles and impurities within the second filter screen 16 from falling out during the rotation of the liquid conduit 4. Instead, they are directed through the liquid conduit hole 5 and the drain hole 14 after they are connected. Furthermore, as the liquid conduit 4 rotates, the concave edges of the cover plates 15 scrape against the tube walls, removing any viscous waste liquid, fine particles, or other materials that could clog the conduit 4, particularly those around the conduit hole 5. These scraped materials are then directed into the drain hole 14 below and ultimately flow to the sediment outlet 11.

[0025] A first filter is provided on the filtrate hole 8, and a second filter 16 with a U-shaped structure is provided on the liquid guiding hole 5. The second filter 16 is located in the inner cavity of the liquid guiding tube 4 and covers the liquid guiding hole 5. The aperture of the first filter is larger than that of the second filter 16. Specifically, the first filter mainly intercepts larger solid waste or debris to prevent them from entering the interior of the liquid guiding tube 4. The second filter 16 has a smaller aperture and collects micro impurities, parts or gravel that pass through the first filter to prevent them from entering the inner cavity of the liquid guiding tube 4 and causing blockage, and collects these solid particle impurities separately by introducing them into the diversion channel. The second filter 16 with a U-shaped structure design can not only increase the filtration area and reduce the probability of single-point blockage, but also, when the flushing liquid is backflushed, the flushing water flow can flush the particles stuck in the U-shaped mesh back into the second filter 16, and then fall into the diversion channel through the drainage hole 14.

[0026] The drive assembly includes a motor 17 and a transmission belt 18. The motor 17 is fixedly mounted at one end of the drain trough 3. The transmission belt 18 is sleeved over one end of the catheter tubes 4. The inner ring of the transmission belt 18 is in transmission connection with several catheter tubes 4, and the outer ring of the transmission belt 18 is in transmission connection with the output end of the motor 17. Specifically, the inner and outer rings of the transmission belt 18 are both equipped with toothed belts. The inner ring of the transmission belt 18 engages with the ends of the catheter tubes 4 via raised pulleys, ensuring that all catheter tubes 4 rotate at the same angle and speed. The outer ring of the transmission belt 18 engages with the output end of the motor 17. By configuring the control system on the motor 17, the number of rotations of the catheter tubes 4 in a single operation is half a turn, that is, the liquid through hole 5 rotates from vertically upward to vertically downward, and then from vertically downward to vertically upward, thereby achieving the functions of sealing, draining, and cleaning.

[0027] Example 2: Based on Example 1, this example proposes a specific working principle of a wastewater treatment device based on a hazardous waste disposal box.

[0028] In the waste liquid discharge mode, the liquid conduit 4 is in the initial state, that is, the liquid conduit hole 5 is facing upward and aligned with the filtrate hole 8 of the support frame plate 7. After the waste liquid in the treatment box 1 is coarsely filtered by the first filter screen, it enters the liquid conduit 4 through the filtrate hole 8 and the liquid conduit hole 5. The waste liquid is finely filtered by the second filter screen 16 in the inner cavity of the liquid conduit 4, and micro impurities are trapped in the second filter screen 16. The pure waste liquid is discharged and collected from the waste liquid port 6 through the connecting conduit 9. Since the flow of the waste liquid will divert impurities with smaller volume and weight to the first filter screen, after the transportation is completed, when the staff loads, unloads or transfers the solid hazardous waste, they can also separately collect the smaller impurities remaining on the first filter screen to avoid them falling during transportation and polluting the surrounding environment. In addition, after the transfer of solid hazardous waste is completed, the bottom of the inner cavity of the treatment box 1 still needs to be cleaned, and under the drainage effect of the waste liquid, the smaller impurities are guided to the first filter screen. Preferably, the first filter screen is a detachable filter screen, which only needs to be taken out and the impurities can be poured into the small impurity storage container separately, thereby increasing the subdivision function of solid waste.

[0029] In the closed mode, the motor 17 controls all the liquid guide tubes 4 to rotate synchronously by 90 degrees, so that the liquid guide holes 5 are misaligned with the filtrate holes 8, and the covering plate 15 closes the channels of the liquid guide holes 5, preventing gas exchange and liquid leakage, and keeping the box dry and airtight.

[0030] In cleaning and slag discharge mode, motor 17 drives liquid conduit 4 to rotate 180°, directing liquid conduit hole 5 vertically downward and connecting it to drain hole 14 in slag separator 13. Flushing fluid is injected through flushing port 10, passing through a one-way valve and into liquid conduit 4 to flush the conduit wall. This fluid flushes impurities trapped within second filter screen 16 from the U-shaped filter, allowing them to fall through drain hole 14 into the diversion channel. The inclined diversion channel, under the influence of the flushing fluid and gravity, directs impurities toward sediment discharge port 11 for centralized discharge.

[0031] Example 3: Based on Example 1, this example proposes a fully automated wastewater treatment device with intelligent linkage and timed cleaning.

[0032] This embodiment is provided with a door panel sensor, a liquid discharge sensor, a timer, a humidity sensor and an intelligent controller. First, after the operator puts the solid hazardous waste into the treatment box 1, the opening and closing door panel 2 is closed. The door panel sensor sends a signal to the controller, and the execution program is: the motor 17 drives the liquid guide tube 4 to rotate 90°, so that the liquid guide hole 5 is misaligned with the filtrate hole 8. The side wall of the liquid guide tube 4 completely closes the filtrate hole 8 of the support frame plate 7, thereby forming a dry and closed environment inside the treatment box 1 to prevent leakage or volatilization of waste liquid during transportation. When it is necessary to open the opening and closing door panel 2, the sensor triggers the drainage instruction, and the execution motor 17 drives the liquid guide tube 4 to rotate 180° until the liquid guide hole 5 faces upward. The liquid guide hole 5 is aligned with the filtrate hole 8, and the waste liquid flows into the liquid guide tube 4 after being filtered through the double-layer filter screen. The waste liquid is discharged from the waste liquid port 6, and the solid particles are trapped in the U-shaped second filter screen 16.

[0033] When executing the automatic cleaning and slag discharge mode, set the trigger timing as follows.

[0034] Condition 1: The discharge volume sensor detects that the waste liquid flow rate is continuously lower than the threshold, indicating that the filter is clogged; Condition 2: The timer reaches the preset cleaning cycle, which is set after every 100kg of hazardous waste processed; Condition 3: The humidity sensor inside the processing box 1 detects an increase in residual liquid vapor.

[0035] Execute action: The motor 17 drives the liquid guide tube 4 to rotate 180 degrees until the liquid guide hole 5 faces downward, and the flushing port 10 injects high-pressure flushing liquid. The flushing liquid flushes the inner wall of the liquid guide tube 4, flushing out impurities in the U-shaped filter screen. The impurities fall into the inclined diversion channel through the drainage hole 14 and are carried by the flushing liquid to the sediment discharge port 11.

[0036] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
