Description

Technical Field

[0001] This invention relates to the field of wastewater testing technology, specifically an emergency sampling and testing device for sudden pollution of industrial wastewater. Background Technology

[0002] Industrial wastewater refers to wastewater containing pollutants (such as chemicals, heavy metals, and organic waste) generated during industrial production processes. It typically originates from industries such as manufacturing, chemicals, metallurgy, energy, and food processing. This wastewater may contain toxic, harmful, or persistent substances, and if discharged directly without treatment, it can cause serious harm to the environment and human health. Industrial wastewater requires emergency pollution detection for the following main reasons: First, it may contain toxic and harmful substances (such as heavy metals, organic pollutants, chemicals, etc.), and sudden leaks or excessive discharges can seriously pollute water bodies, soil, and ecosystems. Second, real-time detection can quickly detect anomalies, avoid large-scale environmental disasters, monitor wastewater discharge in real time, and prevent fines or legal liabilities caused by illegal discharges, while meeting the regulatory requirements of environmental protection departments.

[0003] The prior art discloses Chinese Patent Application No. CN202411436709.6, which discloses a water sampling device for environmental monitoring of treated water bodies. It discloses that the sampling and testing mechanism is triggered by a squeezing mechanism, and the receiving and testing mechanism is activated by the sampling and testing mechanism to conduct testing. This increases the ability to sample and test wastewater at different depths during wastewater sampling and testing, thereby increasing the comprehensiveness and accuracy of the testing process and avoiding the limitation of sampling and testing only on the water surface.

[0004] Although the above-mentioned device can detect water at different depths, it still has some shortcomings in use: 1. When testing industrial wastewater, depending on the characteristics of different industrial wastewaters, the question arises as to whether additives need to be added. Therefore, the above-mentioned device cannot meet the testing needs of different industrial wastewaters and requires the addition of additives for targeted testing. 2. When industrial wastewater is sampled and tested, the wastewater is usually collected and then tested. However, the process from collection to testing often takes a certain amount of time. During this process, the wastewater sample will undergo certain changes in properties during transportation, so it is impossible to "support immediate sampling and testing". Summary of the Invention

[0005] The purpose of this invention is to provide an emergency sampling and detection device for sudden pollution of industrial wastewater, so as to solve the problems mentioned in the background art of how to add additives for targeted detection and how to ensure the authenticity of the detection.

[0006] The objective of this invention can be achieved through the following technical solutions: An emergency sampling and detection device for sudden pollution of industrial wastewater includes a detection box. A sampling unit for sampling water at different water levels is provided on one side of the bottom of the detection box. A drain pipe for discharging the tested water is also provided at the bottom of the detection box. A rotating frame is installed at the bottom of the inner cavity of the detection box by a motor. A central tube is fixedly installed on the top of the rotating frame. A dispensing component is provided on the top of the central tube. Multiple circumferentially arranged slots are opened on the central tube. A collar is fitted on the outside of the central tube. A locking component is provided inside the collar. A detection unit connected to the detection box is provided in the middle of the central tube.

[0007] Preferably, a float is detachably installed on the outside of the detection box, and an anchor cable is fixedly installed at the bottom of the float. The end of the anchor cable away from the float is easy to fix on the slope of the water.

[0008] Preferably, the extraction unit includes a water tank, a telescopic pipe is fixedly installed at the bottom of the water tank, a rectangular frame is fixedly installed on one side of the water tank, a threaded rod is rotatably installed in the inner cavity of the rectangular frame via an electric slider, a movable block is rotatably installed on the threaded rod and slidably connected to the inner wall of the rectangular frame, and a traction rod connected to the telescopic pipe is fixedly installed at one end of the movable block.

[0009] Preferably, multiple circumferentially arranged inclined plates are fixedly installed on the outer edge of the rotating frame. A receiving groove is opened on the side of the inclined plate near the inner wall of the detection box. A scraper is connected to the receiving groove by a spring. The scraper is slidably connected to the receiving groove. Two symmetrically arranged base plates are fixedly installed at the bottom of the rotating frame.

[0010] Preferably, the engaging assembly includes an electric push rod mounted on the top of the collar, a drive ring fixedly mounted on the telescopic end of the electric push rod, a vertical rod circumferentially mounted on the lower end face of the drive ring and sliding within the inner cavity of the collar, an active wedge block fixedly mounted on the bottom of the vertical rod, a driven wedge block fitting on one side of the active wedge block, a crossbar fixedly mounted on one end of the driven wedge block and sliding within the inner wall of the collar, a spring sleeved on the outside of the crossbar, and a locking plate fixedly mounted on one end of the crossbar.

[0011] Preferably, a fixing ring is fixedly installed on the outside of the collar, and multiple circumferentially arranged connecting plates are fixedly installed on the outside of the fixing ring. A threaded ring is installed between the multiple connecting plates. A ring groove is opened on the inner wall of the test box, and a threaded groove is opened in the ring groove. The threaded groove and the threaded ring are connected by a threaded rotation.

[0012] Preferably, the dispensing component includes an I-shaped sleeve fixedly connected to the central tube, a lifting ring is fitted on the outside of the I-shaped sleeve, and multiple circumferentially arranged mounting frames are fixedly installed on the outside of the lifting ring. A storage box is detachably installed inside the mounting frame, and a cover plate is slidably installed on the top of the storage box. A discharge port is opened between the storage box and the mounting frame.

[0013] Preferably, a rubber plug is placed inside the feed port, and a control rod that is rotatably connected to the fixed ring is fixedly installed at the bottom of the rubber plug. A bottom ring is rotatably installed at the bottom of the lifting ring, and multiple circumferentially arranged springs are installed between the bottom ring and the I-shaped sleeve.

[0014] Preferably, the detection unit includes a mounting component fixed outside the detection box. Two symmetrically arranged cylinders are fixedly mounted on the upper end face of the mounting component. A top plate is installed between the two cylinders. A detector is fixedly mounted in the middle of the lower end face of the top plate.

[0015] Preferably, when the locking assembly connects the collar to the central pipe, the dosing assembly adds additives during wastewater detection; when the collar is disconnected from the central pipe, the detection unit directly detects wastewater for which no additives are required.

[0016] The beneficial effects of this invention are: 1. In this invention, the extraction unit can extract wastewater from different depths of the river at multiple points. When additives need to be added to the wastewater, the representativeness of the sample is ensured. The locking component is linked with the dispensing component to automatically and quantitatively add additives, preventing volatilization, oxidation or microbial degradation, and improving detection accuracy. When performing direct detection, the locking component is eliminated, and only stirring is required to prevent sedimentation, simplifying the process. The central tube drives the rotating frame to stir, avoiding impurity sedimentation, ensuring detection stability, reducing manual intervention, and achieving efficient and accurate analysis.

[0017] 2. This invention enables direct sampling and testing in water bodies, eliminating the need for manual collection and transportation, avoiding changes in the properties of wastewater samples during transport, ensuring the authenticity of the test results, and allowing for immediate monitoring in the event of sudden pollution, significantly improving timeliness and enabling a "sampling and testing on demand" mode. This reduces labor and time costs. By driving the threaded rod to rotate via an electric slider, the moving block is raised and lowered, and the extension and retraction of the telescopic tube is controlled by a traction rod, achieving precise sampling of wastewater at different depths. The design of this sampling unit ensures the diversity of sample depths during wastewater testing, thereby significantly improving the accuracy and reliability of the test results.

[0018] 3. This invention employs an inclined plate design to create a vortex flow of wastewater driven by the rotating frame, preventing solid particles from stratifying and settling, ensuring uniform mixing of wastewater, reducing local concentration differences during testing, and improving testing accuracy. The continuous scraping between the scraper and the inner wall of the testing chamber, as well as the scraping of the bottom by the bottom plate, effectively removes mud and dirt adhering to the inner wall and bottom, reducing residual pollution and keeping the testing environment clean. Stirring and cleaning are completed simultaneously without additional operation, which optimizes the testing process, avoids errors that may be introduced by manual intervention, reduces mud and dirt accumulation, extends equipment life, and reduces maintenance frequency and costs.

[0019] 4. This invention uses a locking assembly to fix the collar and the central tube. When additives are added to the wastewater, the electric push rod retracts, causing the drive ring to move downwards. Simultaneously, the drive ring moves multiple vertical rods downwards, causing the active wedge block to move downwards within the collar's inner cavity. The active wedge block, as it moves downwards, presses against the driven wedge block. This pressure causes the driven wedge block to move via a crossbar, moving the locking plate until it reaches the slot on the central tube. At this point, the collar and the central tube are fixed. When the central tube rotates, it simultaneously rotates the collar. The rotation of the collar, through multiple connecting plates, causes the threaded ring to rotate, which in turn causes the collar and the locking assembly to move up and down within the slot.

[0020] 5. This invention uses multiple storage boxes to accommodate various additives, thus enabling automatic addition of multiple additives. The cover plate allows for the filling and sealing of manually replenished additives in the storage boxes, preventing additives from scattering during high-speed rotation of the central tube. When the threaded ring rotates, it drives the collar and locking assembly to move up and down within the slot. Simultaneously, the control rod causes the rubber stopper to intermittently unblock the discharge port. At this time, the additives in the storage boxes fall into the rotating frame through the discharge port, achieving quantitative addition of additives during wastewater treatment. Furthermore, the rotation of the frame also stirs the additives, accelerating the mixing of additives and wastewater. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] As attached Figure 1-8 As shown, an emergency sampling and detection device for sudden pollution of industrial wastewater includes a detection box 1. A sampling unit for sampling water at different water levels is provided on one side of the bottom of the detection box 1. A drain pipe 14 for discharging the tested water is also provided at the bottom of the detection box 1. A rotating frame 2 is installed at the bottom of the inner cavity of the detection box 1 by a motor. A central tube 24 is fixedly installed on the top of the rotating frame 2. A dispensing component is provided on the top of the central tube 24. Multiple circumferentially arranged slots 241 are opened on the central tube 24. A collar 25 is sleeved on the outside of the central tube 24. A locking component is provided inside the collar 25. A detection unit connected to the detection box 1 is provided in the middle of the central tube 24. The extraction unit allows for multi-point extraction of wastewater from different depths within the river channel, bringing the sampled wastewater into the testing chamber 1. When testing unstable industrial wastewater, additives are added before testing to avoid the volatile and easily oxidized characteristics of the pollutants. However, for wastewater with a single composition, high concentration, and stable properties, direct testing is possible. When testing wastewater requiring additives, the locking assembly facilitates the locking and fixing of the collar 25 and the central tube 24. When the motor is turned on, rotating the central tube 24, the dispensing assembly automatically adds the additive to the sampled wastewater in the testing chamber 1. Adding additives to specific wastewater inhibits microbial activity, preventing the analyte from being degraded during settling and converting the analyte into a detectable form. It also prevents the accumulation of suspended solids, thereby improving the accuracy and stability of the test. For qualitative and efficiency testing, when testing wastewater that does not require additives, the locking assembly is released from engagement with the central tube 24. At this time, the collar 25 cannot rotate with the central tube 24. When the central tube 24 drives the rotating frame 2 to stir the wastewater at the bottom of the testing chamber 1, the additive component is released from adding additives to the wastewater. The rotation of the rotating frame 2 driven by the central tube 24 can stir the wastewater, preventing the substances in the wastewater from settling. Therefore, the testing effect is more accurate. The setting of the testing unit can perform testing on the wastewater collected inside the testing chamber 1. Compared with the existing device, when testing wastewater, the present invention can selectively add additives to the wastewater according to the type of wastewater while using the stirring of the wastewater to prevent the sedimentation of its internal impurities. Moreover, no manual addition is required when adding additives, realizing automatic quantitative and accurate addition of additives. The tested wastewater can be discharged through the drain pipe 14.

[0025] As attached Figure 1 As shown, a float 10 is detachably installed on the outside of the detection box 1. An anchor cable 11 is fixedly installed at the bottom of the float 10. The end of the anchor cable 11 away from the float 10 is easy to fix on the slope of the water. The float 10 enables the detection box 1 to float in the river. After being fixed to the riverbank by one end of the anchor cable 11, the float 10 can easily move the detection box 1 to the surface of the water, realizing the device's autonomous floating in the water and supporting the immediate sampling and testing mode. Compared with existing devices, when sampling and testing wastewater, this invention can be placed in the water for sampling and testing, eliminating the need for manual extraction of wastewater from the river for testing. This saves the manual sampling process, avoids changes in the properties of the sample during transportation, and significantly improves the response speed for immediate testing. It is particularly suitable for monitoring sudden pollution events, improving the efficiency and convenience of wastewater testing.

[0026] As attached Figure 3As shown, the extraction unit includes a water tank 15, a telescopic pipe 151 is fixedly installed at the bottom of the water tank 15, a rectangular frame 152 is fixedly installed on one side of the water tank 15, a threaded rod 153 is rotatably installed in the inner cavity of the rectangular frame 152 via an electric slider, a movable block 154 is rotatably installed on the threaded rod 153 and slidably connected to the inner wall of the rectangular frame 152, and a traction rod 155 connected to the telescopic pipe 151 is fixedly installed at one end of the movable block 154. The properties of industrial wastewater may vary significantly at different depths, mainly due to water stratification, uneven distribution of pollutants, and changes in physicochemical conditions. Therefore, it is necessary to test wastewater at different depths when testing industrial wastewater. When sampling wastewater at different depths, the electric slider is activated, driving the threaded rod 153 to rotate. When the threaded rod 153 rotates, it drives the moving block 154 to rise and fall. When the moving block 154 rises and falls, it drives the telescopic tube 151 to extend and retract via the traction rod 155. When one end of the telescopic tube 151 is placed in the wastewater, the water pump in the pumping tank 15 is turned on to extract wastewater at different depths into the testing tank 1. In this invention, the sampling unit can sample wastewater at different depths during wastewater testing, thereby ensuring the accuracy of wastewater testing.

[0027] As attached Figure 6 As shown, multiple circumferentially arranged inclined plates 20 are fixedly installed on the outer edge of the rotating frame 2. An accommodating groove is opened on the side of the inclined plate 20 near the inner wall of the detection box 1. A scraper 21 is connected to the accommodating groove by a spring. The scraper 21 is slidably connected to the accommodating groove. Two symmetrically arranged bottom plates 22 are fixedly installed at the bottom of the rotating frame 2. When the motor starts and drives the rotating frame 2 to rotate, the inclined plate 20 set on the outer edge of the rotating frame 2 can form a vortex-like efficient stirring of the wastewater in the detection box 1, so as to avoid the solid particles in the wastewater from stratification and sedimentation when they are still, which would cause the detection deviation due to local concentration differences. When the rotating frame 2 rotates, the scraper 21 continuously scrapes against the inner wall of the detection box 1, and the bottom plate 22 scrapes against the bottom of the inner cavity of the detection box 1, which can remove the sediment on the inner wall of the detection box 1 at the same time.

[0028] As attached Figure 8 As shown, the engaging assembly includes an electric push rod 251 mounted on the top of the collar 25. A drive ring 252 is fixedly mounted on the telescopic end of the electric push rod 251. A vertical rod 253 is circumferentially mounted on the lower end face of the drive ring 252, penetrating and sliding within the inner cavity of the collar 25. An active wedge block 254 is fixedly mounted on the bottom of the vertical rod 253. A driven wedge block 255 is fitted on one side of the active wedge block 254. A horizontal rod 256 is fixedly mounted on one end of the driven wedge block 255, penetrating and sliding within the inner wall of the collar 25. A spring is sleeved on the outside of the horizontal rod 256. A locking plate 257 is fixedly mounted on one end of the horizontal rod 256. When the control engagement assembly secures the collar 25 and the central tube 24 to allow for the addition of additives to the wastewater, the electric push rod 251 retracts. At this time, the electric push rod 251 drives the drive ring 252 downwards. Simultaneously, the drive ring 252 moves downwards, driving multiple vertical rods 253 downwards. As the vertical rods 253 move downwards, they drive the active wedge block 254 downwards within the collar 25. During this downward movement, the active wedge block 254 presses against the driven wedge block 255. At this time, the driven wedge block... After the wedge block 255 is compressed, it drives the clamping plate 257 to move through the crossbar 256 until the clamping plate 257 moves into the slot 241 opened on the central tube 24. At this time, the collar 25 is fixed to the central tube 24. When the central tube 24 rotates, it drives the collar 25 to rotate synchronously. When the collar 25 rotates, it drives the threaded ring 262 to rotate through multiple connecting plates 261. When the threaded ring 262 rotates, it drives the collar 25 and the engaging assembly to move up and down in the slot 241.

[0029] As attached Figure 4 , Figure 5 As shown, a fixing ring 26 is fixedly installed on the outside of the collar 25, and multiple circumferentially arranged connecting plates 261 are fixedly installed on the outside of the fixing ring 26. A threaded ring 262 is installed between the multiple connecting plates 261. A ring groove 12 is opened on the inner wall of the test box 1, and a threaded groove 13 is opened in the ring groove 12. The threaded groove 13 and the threaded ring 262 are connected by a threaded rotation.

[0030] As attached Figure 7 As shown, the dispensing component includes an I-shaped sleeve 3 fixedly connected to the central tube 24. A lifting ring 31 is sleeved on the outside of the I-shaped sleeve 3. Multiple circumferentially arranged mounting frames 32 are fixedly installed on the outside of the lifting ring 31. A storage box 33 is detachably installed inside the mounting frame 32. A cover plate 34 is slidably installed on the top of the storage box 33. A discharge port 35 is opened between the storage box 33 and the mounting frame 32. Multiple storage tanks 33 are provided to accommodate various additives, thus enabling automatic addition of multiple additives. The cover plate 34 allows for the filling and sealing of additives pre-added manually in the storage tanks 33, preventing additives from scattering during high-speed rotation of the central tube 24. When the threaded ring 262 rotates, it drives the collar 25 and the locking assembly to move up and down in the slot 241. The control rod 37 then drives the rubber stopper 36 to intermittently unblock the discharge port 35. At this time, the additives in the storage tanks 33 fall into the rotating frame 2 through the discharge port 35, realizing the quantitative addition of additives during wastewater treatment. Furthermore, the rotation of the rotating frame 2 can also stir the additives, accelerating the mixing of additives and wastewater.

[0031] A rubber plug 36 is placed inside the discharge port 35. A control rod 37 that is rotatably connected to the fixed ring 26 is fixedly installed at the bottom of the rubber plug 36. A bottom ring 38 is rotatably installed at the bottom of the lifting ring 31. Multiple circumferentially arranged springs are installed between the bottom ring 38 and the I-shaped sleeve 3. The spring design allows the control lever 37 to move the rubber stopper 36 downwards to cancel the blockage of the discharge port 35. When the lifting ring 31 moves downwards, it compresses the spring. At this time, the lifting ring 31, under the action of the spring, causes the storage box 33 to shake up and down, which can effectively prevent the additive from clogging in the discharge port 35 and affecting the material discharge.

[0032] As attached Figure 1 , Figure 2 As shown, the detection unit includes a mounting component 4 fixed outside the detection box 1. Two symmetrically arranged cylinders 41 are fixedly installed on the upper end face of the mounting component 4. A top plate 42 is installed between the two cylinders 41. A detector 43 is fixedly installed in the middle of the lower end face of the top plate 42. The retraction of cylinder 41 can drive detector 43 through central tube 24 and place it in the middle of rotating frame 2, thereby facilitating the detection of wastewater inside rotating frame 2. It should be noted that the detection of wastewater by the detector 43 is existing technology, so it will not be elaborated on further.

[0033] When the locking assembly connects the collar 25 to the central pipe 24, the dosing assembly adds additives during wastewater detection. When the collar 25 is disconnected from the central pipe 24, the detection unit directly detects wastewater that does not require the addition of additives.

[0034] In use, after one end of the anchor cable 11 is fixed to the riverbank, the float 10 facilitates the placement of the detection box 1 on the surface of the water. The extraction unit allows for multi-point extraction of wastewater at different depths within the river, bringing the sampled wastewater into the detection box 1. When testing unstable industrial wastewater, to avoid the volatile and easily oxidized characteristics of the polluted wastewater, additives need to be added before testing. However, when encountering wastewater with a single component, high concentration, and stable properties, direct testing is possible. When testing wastewater requiring additives, the locking assembly facilitates the locking and fixing of the collar 25 and the central tube 24. When the motor is turned on and drives the central tube 24 to rotate, the dispensing assembly automatically dispenses the additives into the sampled wastewater in the detection box 1. By adding additives to specific wastewater, microbial activity can be inhibited to prevent the analyte from being degraded during settling, thus converting the analyte into a detectable form. On the other hand, it can also prevent the aggregation of suspended solids, thereby improving the accuracy, stability and efficiency of detection. When detecting wastewater that does not require the addition of additives, the locking component is released from the locking with the central tube 24. At this time, the collar 25 cannot rotate with the central tube 24. When the central tube 24 drives the rotating frame 2 to stir the wastewater at the bottom of the detection box 1, the addition component cancels the addition of additives to the wastewater. The rotation of the rotating frame 2 driven by the central tube 24 can stir the wastewater and prevent the substances in the wastewater from settling. Therefore, the detection effect is more accurate. The detection unit can perform detection operations on the wastewater collected inside the detection box 1. Compared with the existing device, when detecting wastewater, the present invention can selectively add additives to the wastewater according to the type of wastewater and prevent the sedimentation of internal impurities by stirring the wastewater. Moreover, no manual addition is required when adding additives, realizing automatic quantitative and accurate addition of additives. The properties of industrial wastewater can vary significantly at different depths, mainly due to water stratification, uneven pollutant distribution, and changes in physicochemical conditions. Therefore, it is necessary to test wastewater at different depths when conducting industrial wastewater testing. When extracting wastewater from different depths for testing, the electric slider activates, causing the threaded rod 153 to rotate. The rotation of the threaded rod 153 then drives the moving block 154 to rise and fall. The rising and falling of the moving block 154, via the traction rod 155, causes the telescopic pipe 151 to extend and retract. When one end of the telescopic tube 151 is placed in the wastewater, the water pump in the pumping tank 15 can be turned on to draw wastewater from different depths into the detection tank 1. This invention, when detecting wastewater, can sample wastewater from different depths through the set extraction unit, thus ensuring the accuracy of wastewater detection. When the motor is turned on and drives the rotating frame 2 to rotate, the inclined plate 20 set on the outer edge of the rotating frame 2 can form a vortex-like efficient stirring of the wastewater in the detection tank 1, avoiding stratification and sedimentation of solid particles in the wastewater when they are still, which could lead to detection deviations due to local concentration differences. As the rotating frame 2 rotates, the scraper 21 continuously scrapes against the inner wall of the detection tank 1, and the bottom plate 22 scrapes against the bottom of the inner cavity of the detection tank 1, simultaneously removing sediment from the inner wall of the detection tank 1. The locking assembly controls the fixing of the collar 25 and the central tube 24. When selecting to add additives to wastewater, the electric push rod 251 is retracted. At this time, the electric push rod 251 drives the drive ring 252 to move down. When the drive ring 252 moves down, it simultaneously drives multiple vertical rods 253 to move down. When the vertical rods 253 move down, they drive the active wedge block 254 to move down in the inner cavity of the collar 25. When the active wedge block 254 moves down, it squeezes the driven wedge block 255. When the driven wedge block 255 is squeezed, it drives the clamping plate 257 to move through the cross rod 256 until the clamping plate 257 moves into the slot 241 opened on the central tube 24. At this time, the collar 25 is fixed to the central tube 24. When the central tube 24 rotates, it drives the collar 25 to rotate simultaneously. When the collar 25 rotates, it drives the threaded ring 262 to rotate through multiple connecting plates 261. When the threaded ring 262 rotates, it drives the collar 25 and the locking assembly to move up and down in the slot 241. Multiple storage boxes 33 are provided to accommodate various additives, thus enabling automatic addition of multiple additives. The cover plate 34 allows for the filling and sealing of manually replenished additives within the storage boxes 33, preventing additives from scattering during high-speed rotation of the central tube 24. When the threaded ring 262 rotates, it drives the collar 25 and the locking assembly to move up and down within the slot 241. The control rod 37 then intermittently unblocks the discharge port 35 with the rubber stopper 36. At this time, the additives in the storage boxes 33 fall through the discharge port 35 into the rotating frame 2, achieving quantitative addition of additives during wastewater treatment. Furthermore, the rotation of the rotating frame 2 also agitates the additives, accelerating their mixing with the wastewater. When the control rod 37 moves the rubber stopper 36 downwards to unblock the discharge port 35, the lifting ring 31 moves downwards and compresses the spring. Under the action of the spring, the lifting ring 31 causes the storage boxes 33 to vibrate up and down, effectively preventing additive blockage in the discharge port 35 and affecting the discharge.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
