Description
Technical Field
[0001] The utility model relates to the technical field of experimental tables, and more specifically, to an experimental table with a wastewater treatment function. Background Technique
[0002] Experimental tables are commonly used devices in laboratories of hospitals, schools, chemical plants, research institutes and other units for experimental testing, used to install and place experimental instruments or equipment, and different experiments have different requirements for experimental tables.
[0003] For existing experimental tables, in order to treat some wastewater generated during experiments, a pool or sink is installed on the tabletop of the experimental table, and a wastewater treatment box is equipped below the pool inside the experimental table. The wastewater treatment box is connected to the pool through a water pipe. In this way, the wastewater generated during experiments will be poured into the pool by users, and finally the wastewater flows into the wastewater treatment box. Although the purpose of treating wastewater is achieved, the pool occupies a large area of the tabletop of the experimental table. When we do some other experiments that do not generate wastewater, the existence of the pool will affect the placement of many devices, making the original experimental table no longer a complete tabletop, and some areas that could have placed experimental equipment are occupied by the pool, which is rather inconvenient. Content of the Utility Model
[0004] The purpose of the utility model is to provide an experimental table with a wastewater treatment function to solve the problems raised in the above background technique:
[0005] For existing experimental tables, in order to treat some wastewater generated during experiments, a pool or sink is installed on the tabletop of the experimental table, and a wastewater treatment box is equipped below the pool inside the experimental table. The wastewater treatment box is connected to the pool through a water pipe. In this way, the wastewater generated during experiments will be poured into the pool by users, and finally the wastewater flows into the wastewater treatment box. Although the purpose of treating wastewater is achieved, the pool occupies a large area of the tabletop of the experimental table. When we do some other experiments that do not generate wastewater, the existence of the pool will affect the placement of many devices, making the original experimental table no longer a complete tabletop, and some areas that could have placed experimental equipment are occupied by the pool, which is rather inconvenient.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] An experimental table with wastewater treatment function, including the main body of the experimental table. An opening is provided on the upper surface of the main body of the experimental table. A water pool is fixedly connected inside the main body of the experimental table and below the opening. Inside the main body of the experimental table and below the water pool, a wastewater treatment box is provided. The wastewater treatment box is communicated with the water pool through a water pipe. The wastewater introduced into the water pool by the user will flow into the wastewater treatment box through the water pipe for centralized treatment. A mounting plate is fixedly connected to one side of the water pool. A rotating shaft is rotatably connected between the mounting plate and the water pool. A motor is fixedly connected to the outer side of the mounting plate away from the water pool. The rotating shaft is fixedly connected to the output end of the motor. A first swing plate is fixedly connected to the outer side of the rotating shaft. A baffle is rotatably connected to the outer end of the first swing plate away from the rotating shaft. The bottom of the baffle is rotatably connected to a second swing plate. The second swing plate is rotatably connected to the water pool. The first swing plate and the second swing plate have the same size. The positions where the baffle, the first swing plate, the second swing plate and the water pool rotate relative to each other form a parallelogram. When the first swing plate swings back and forth, it can drive the baffle to combine with or separate from the opening. A set of first swing plate and second swing plate are also provided on the other side of the water pool to support the baffle.
[0008] Preferably, a rotating rod is rotatably connected inside the water pool. There are two rotating rods in total. The two rotating rods are symmetrically distributed. A sleeve is fixedly connected to the outer side of the rotating rod. A sliding rod is slidably connected inside the sleeve. A spring is fixedly connected between the sliding rod and the sleeve. A scraping plate is fixedly connected to the outer end of the sliding rod away from the spring. The scraping plate is used in cooperation with the water pool. The elastic force of the spring makes the scraping plate on the sliding rod always press against the inner wall of the water pool, ensuring the effective cleaning of the inner wall of the water pool by the scraping plate.
[0009] Preferably, the rotating rod vertically penetrates through the water pool and extends to the outside of the water pool. A first gear is fixedly connected to one end of the rotating rod. The two first gears mesh with each other. A second gear is rotatably connected to the outside of the water pool. One of the first gears is meshed with the second gear. A third gear is fixedly connected to the outer side of the second swing plate. The third gear is meshed with the second gear. When the second swing plate swings back and forth, it will drive the third gear to rotate. The third gear drives the symmetrically arranged rotating rods to rotate simultaneously through the second gear and the first gear.
[0010] Preferably, a control switch is fixedly connected to the outside of the main body of the experimental table. The motor is electrically connected to the control switch. The forward and reverse rotation of the motor is controlled by the control switch. It is powered by an external power supply such as mains electricity, which is a well-known prior art and will not be elaborated too much.
[0011] Preferably, the mounting plate is of L-shaped structure. The L-shaped mounting plate has a certain gap between itself and the water pool, so that the rotating shaft driving the first swing plate to swing back and forth will not be hindered.
[0012] Preferably, the cross-sections of the sleeve and the sliding rod are both square structures, and the outer side wall of the sliding rod fits against the inner side wall of the sleeve. Since the cross-sections of the sleeve and the sliding rod are both square structures, the sliding rod inside the sleeve can be limited, so that the sliding rod can only slide back and forth inside the sleeve, and there will be no situation where the sliding rod twists inside the sleeve, so that the scraper on the sliding rod will not be misaligned with the inner wall of the pool, nor will it get stuck.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] 1) When the experimental bench with the function of wastewater treatment is in use, when wastewater is generated during the experiment and needs to be treated, control the motor to rotate forward. The motor drives the first swing plate to swing forward through the rotating shaft, and cooperates with the second swing plate to drive the baffle to separate from the opening on the experimental bench main body until the baffle moves to one side position of the opening. At this time, the pool is exposed, and the user can pour the wastewater generated by the experiment into the pool. After the wastewater is poured, control the motor to rotate in reverse to bring the baffle back and combine it with the opening. After the baffle is combined with the opening, the entire tabletop of the experimental bench main body is complete, and experimental equipment can also be placed on the baffle, so the available area is larger, and there will be no situation where the tabletop of the experimental bench main body is reduced due to the existence of the pool and other experimental equipment cannot be placed.
[0015] 2) When the experimental bench with the function of wastewater treatment is in use, when the baffle is opened, the second swing plate will drive the third gear to rotate. The third gear drives two symmetrically arranged rotating rods to rotate simultaneously through the second gear and the first gear, and the rotation directions of these two rotating rods are opposite, so that the rotating rods drive the scraper to rotate from bottom to top through the sleeve and the sliding rod. When the baffle is closed, the scraper will rotate from top to bottom to automatically clean the inner wall of the pool to ensure the cleanliness of the inner wall of the pool.

[0021] In the existing experimental bench, in order to treat the wastewater generated during some experiments, a water tank or sink is installed on the tabletop of the experimental bench, and a wastewater treatment tank is equipped below the water tank inside the experimental bench. The wastewater treatment tank is connected to the water tank through a water pipe. In this way, the wastewater generated during the experiment will be poured into the water tank by the user, and finally the wastewater will flow into the wastewater treatment tank. Although the purpose of treating the wastewater is achieved, the water tank occupies a large area of the tabletop of the experimental bench. When we do some other experiments that do not generate wastewater, the presence of the water tank will affect the placement of many devices, making the original experimental bench no longer a complete tabletop. Some areas that could originally place experimental equipment are occupied by the water tank, which is rather inconvenient. This problem is solved by the following solution.
[0022] Please refer to Figures 1 to 4 , an experimental bench with wastewater treatment function, including the main body 1 of the experimental bench. An opening 2 is provided on the upper surface of the main body 1 of the experimental bench. A water tank 3 is fixedly connected inside the main body 1 of the experimental bench and below the opening 2. Inside the main body 1 of the experimental bench, below the water tank 3, a wastewater treatment tank is provided. The wastewater treatment tank is communicated with the water tank 3 through a water pipe. The wastewater imported by the user into the water tank 3 will flow into the wastewater treatment tank through the water pipe for centralized treatment. One side of the water tank 3 is fixedly connected with a mounting plate 4. A rotating shaft 5 is rotatably connected between the mounting plate 4 and the water tank 3. A motor 6 is fixedly connected to the outside of the mounting plate 4 and away from the water tank 3. The rotating shaft 5 is fixedly connected to the output end of the motor 6. A first swing plate 7 is fixedly connected to the outside of the rotating shaft 5. One end of the first swing plate 7 away from the rotating shaft 5 is rotatably connected with a baffle 8. The bottom of the baffle 8 is rotatably connected with a second swing plate 9. The second swing plate 9 is rotatably connected with the water tank 3. The first swing plate 7 and the second swing plate 9 have the same size. The positions where the baffle 8, the first swing plate 7, the second swing plate 9 and the water tank 3 rotate relative to each other are connected to form a parallelogram. When the first swing plate 7 swings back and forth, it can drive the baffle 8 to combine with or separate from the opening 2. A set of first swing plate 7 and second swing plate 9 are also provided on the other side of the water tank 3 to support the baffle 8 and ensure the stability of the baffle 8.
[0023] The pool 3 is internally rotatably connected with a rotating rod 10, and there are two rotating rods 10, which are symmetrically distributed. The outside of the rotating rod 10 is fixedly connected with a sleeve 11, and the inside of the sleeve 11 is slidably connected with a slide bar 12, and a spring 13 is fixedly connected between the slide bar 12 and the sleeve 11, and the end of the slide bar 12 away from the spring 13 is fixedly connected with a scraper 14, and the scraper 14 is used in conjunction with the pool 3. The elastic force of the spring 13 makes the scraper 14 on the slide bar 12 always press against the inner wall of the pool 3, ensuring that the scraper 14 effectively cleans the inner wall of the pool 3. When the rotating rod 10 rotates, the scraper 14 will be driven by the sleeve 11 and the slide bar 12 to clean the inner wall of the pool 3.
[0024] The rotating rod 10 vertically penetrates the pool 3 and extends to the outside of the pool 3. One end of the rotating rod 10 is fixedly connected to a first gear 15, and the two first gears 15 are meshed with each other. The outside of the pool 3 is rotatably connected to a second gear 16, and one of the first gears 15 is meshed with the second gear 16. The outside of the second swing plate 9 is fixedly connected to a third gear 17, and the third gear 17 is meshed with the second gear 16. When the second swing plate 9 swings back and forth, it drives the third gear 17 to rotate. The third gear 17 drives one of the first gears 15 to rotate through the second gear 16, and finally drives the symmetrically arranged rotating rods 10 to rotate simultaneously through the two meshed first gears 15.
[0025] The outside of the experimental table body 1 is fixedly connected with a control switch 18, and the motor 6 is electrically connected to the control switch 18. The forward and reverse rotation of the motor 6 is controlled by the control switch 18, and the power is supplied by an external power supply such as AC power. This is a well-known technology and will not be described in detail.
[0026] The mounting plate 4 is an L-shaped structure, and a certain gap exists between the mounting plate 4 and the pool 3, which is conducive to the rotation shaft 5 driving the first swing plate 7 to swing back and forth without being hindered.
[0027] The cross-sections of the sleeve 11 and the slide rod 12 are both square structures, and the outer wall of the slide rod 12 fits with the inner wall of the sleeve 11. Since the cross-sections of the sleeve 11 and the slide rod 12 are both square structures, the slide rod 12 in the sleeve 11 can be limited so that the slide rod 12 can only slide back and forth in the sleeve 11, and the slide rod 12 will not twist in the sleeve 11, so that the scraper 14 on the slide rod 12 will not be offset from the inner wall of the pool 3, and will not get stuck, thereby ensuring the effect of the scraper 14 on cleaning the inner wall of the pool 3.
[0028] Usage steps of the utility model: When this experimental bench with wastewater treatment function is in use and wastewater is generated during the experiment that needs to be treated, the user controls the motor 6 to rotate forward through the control switch 18. The motor 6 drives the first swing plate 7 to swing forward through the rotating shaft 5, and cooperates with the second swing plate 9 to drive the baffle 8 to separate from the opening 2 on the experimental bench main body 1. During this process, the second swing plate 9 will drive the third gear 17 to rotate, and the third gear 17 drives two symmetrically arranged rotating rods 10 to rotate simultaneously through the second gear 16 and the first gear 15, and the rotation directions of these two rotating rods 10 are opposite, so that the rotating rods 10 drive the scraper 14 to rotate from bottom to top through the sleeves 11 and the sliding rods 12 until the baffle 8 moves to one side of the opening 2. At this time, the water tank 3 is exposed, and the user can pour the wastewater generated by the experiment into the water tank 3. After pouring the wastewater, control the motor 6 to reverse, bring the baffle 8 back and combine it with the opening 2. During this process, the scraper 14 rotates from top to bottom to automatically clean the inner wall of the water tank 3 to ensure the cleanliness of the inner wall of the water tank 3. After the baffle 8 is combined with the opening 2, the entire tabletop of the experimental bench main body 1 is complete, and experimental equipment can also be placed on the baffle 8, with a larger available area.
