The plurality of collection barrels 9 are located on the top of the rotating table 8. The bottom end of the fixed shaft 12 is fixedly connected with the rotating table 8. When the first motor 13 is started, the fixed shaft 12 will rotate, thereby driving the rotating table 8 and the collection barrels 9 to rotate. According to the type of wastewater, the corresponding collection barrel 9 is selectively moved to the lower side of the guide pipe 21 to receive the wastewater. The movement mechanism of the first motor 13 can be manually controlled by a controller. According to the type of the corresponding waste liquid, the corresponding button is pressed to control the start of the first motor 13, so that the corresponding collection barrel 9 is moved into position. The top end of the collection barrel 9 abuts against the sealing plate 7, and the top end of the collection barrel 9 is provided with a sealing gasket for sealing the liquid in the collection barrel 9, which can effectively prevent the gas generated during storage from entering the laboratory.

[0038] The rotating table 8 is provided with a positioning member for positioning the collection barrel 9. The positioning member includes a positioning groove 18 opened on the top of the rotating table 8. The collection barrel 9 is located in the positioning groove 18. One side of the positioning groove 18 is integrally formed with a plug rod 19. The outer wall of the collection barrel 9 is provided with a plug hole for plug connection with the plug rod 19. When placed, the collection barrel 9 is only pushed into the positioning groove 18 until the plug rod 19 is inserted into the plug hole, so that the collection barrel 9 can be stably fixed on the rotating table 8. The plug rod 19 and the plug hole are interference fit, which can ensure the stability of the collection barrel 9.

[0039] The test bench 1 is also provided with a filtering assembly for filtering wastewater. The filtering assembly includes two rotating seats 4 fixed by welding on the bottom of the water tank 2. The two rotating seats 4 are both provided with rotating rollers 26 rotatably connected by bearings. One of the rotating rollers 26 is fixedly provided with a filter cloth 5. The filter cloth 5 is made of high-efficiency filtering material, such as reverse osmosis membrane. The top surface of the filter cloth 5 is provided with protruding portions on both sides, so that the upper surface of the filter cloth 5 is recessed, avoiding the scattering of impurities filtered out, and effectively filtering impurities in the wastewater. The other end of the filter cloth 5 is fixedly connected with the other rotating roller 26. One side of one of the rotating seats 4 is provided with a second motor 27 fixed by bolts. The output end of the second motor 27 is fixedly connected with the rotating roller 26 on one side, for driving the rotating roller 26 to rotate and wind the used filter cloth 5. The corresponding rotating roller 26 can be driven to rotate by starting the second motor 27, so as to wind the filter cloth 5.

[0040] As Figure 3As shown, the transmission for driving the guide pipe 21 and the collecting cylinder 9 to approach each other includes the electric push rod 23 fixed outside the guide pipe 21 by bolts, the output end of the electric push rod 23 is fixed with the pressing plate 20 by welding, the bottom of the pressing plate 20 is penetrated and welded with the sliding pipe 22, the top end of the sliding pipe 22 is slidably arranged in the guide pipe 21, and the top of the sealing plate 7 is provided with the clearance hole 17 corresponding to the pressing plate 20. When the electric push rod 23 is started, the pressing plate 20 is pushed to move downward, the sliding pipe 22 slides in the guide pipe 21, and then the guide pipe 21 and the collecting cylinder 9 approach each other until the guide pipe 21 is inserted into the collecting cylinder 9, so that the wastewater can flow into the collecting cylinder 9, and the wastewater is prevented from overflowing. The filter cloth 5 is located between the guide pipe 21 and the collecting cylinder 9, and can filter and purify the wastewater. Figure 6 、 7 As shown, the bottom end of the sliding pipe 22 is provided with the tapered head 33, the outer wall of the tapered head 33 is provided with a plurality of rectangular grooves 34, and the inner wall of the collecting cylinder 9 is fixed with the abutting rod 36 corresponding to the rectangular grooves 34 by welding. When the sliding pipe 22 moves downward, the tapered head 33 will contact the abutting rod 36, the shape of the filter cloth 5 is changed by the extrusion of the rectangular grooves 34 and the abutting rod 36, the contact area with the waste liquid is increased by using the deformed lace-shaped tapered filter cloth 5, and the filtering effect is improved.

[0041] As shown, Figure 5 The guide pipe 21 is also provided with a cleaning member for cleaning the tapered head 33, the cleaning member includes a plurality of elastic rods 32 fixed on the inner wall of the guide pipe 21 by welding, the elastic rod 32 is L-shaped and has elasticity, and the bottom end of the elastic rod 32 is fixed with the cleaning block 35 abutting against the inner wall of the tapered head 33 by welding. When the tapered head 33 moves upward, the cleaning block 35 cleans the inner wall of the tapered head 33, preventing impurities from remaining, and the top end of the guide pipe 21 is internally tapered, so that the top end of the guide pipe 21 has no step, which helps the flow of wastewater and prevents impurities from remaining on the top end of the guide pipe 21. The top end of the cleaning block 35 is also provided with an inclined surface, so that the top end of the cleaning block 35 has no step, avoiding impurities remaining on the top end of the cleaning block 35.

[0042] The top of the pressing plate 20 is fixed with the connecting frame 24 by welding, the other end of the connecting frame 24 is fixed with the rack 25, the other rotating roller 26 is sleeved with the gear 28 engaged with the rack 25, and the gear 28 and the rotating roller 26 have resistance therebetween and rotate together under the condition of no external force. When the pressing plate 20 moves downward, the connecting frame 24 and the rack 25 will move downward, the rack 25 will drive the gear 28 to rotate, and then the other rotating roller 26 will rotate, so that the filter cloth 5 remains loose, avoiding the filter cloth 5 being poked by the guide pipe 21 when the guide pipe 21 moves to the collecting cylinder 9. At the same time, the bottom of the two ends of the pressing plate 20 is arc-shaped, which helps the movement of the filter cloth 5 and reduces the friction with the filter cloth 5.

[0043] The test bench 1 also has a burning assembly for burning the filtered impurities and the used filter cloth 5. The burning assembly includes a furnace body 11 fixed on the bottom wall of the test bench 1 by bolts, a combustion chamber is arranged in the furnace body 11, a burner 40 is arranged in the combustion chamber, the burner is the burner in the patent document CN111895400B, a double-layer grate 37 is arranged in the combustion chamber, and an exhaust end on the furnace body 11 extends to outdoor flue gas treatment equipment through a pipeline. A connecting pipe 38 is arranged in communication with the top of the furnace body 11, a cutter 39 is fixed on the top of the connecting pipe 38 by welding, and a groove 31 is arranged on the bottom of the pressing plate 20 and matched with the cutter 39. During the filtering process, when the used filter cloth 5 is located above the cutter 39, the pressing plate 20 moves downward, and the cutter 39 cuts into the groove 31 to cut the used filter cloth 5. As shown in Figure 4 The top of the pressing plate 20 penetrates and slides the top rod 29, the outer wall of the top rod 29 is sleeved with the spring 30, and the two ends of the spring 30 are respectively abutted with the bottom end outer wall of the top rod 29 and the top wall of the groove 31 through the spring seat. When the filter cloth 5 is cut off, the spring 30 pushes the top rod 29 to move downward, and the top rod 29 pushes the cut filter cloth 5 into the connecting pipe 38 and into the furnace body 11 for burning. After the filter cloth 5 is straightened, the top rod 29 can be abutted to move upward and compress the spring 30. The spring 30 is made of stainless steel, with a wire diameter of 0.8-1.2 mm, an outer diameter of 8-12 mm, and an elastic coefficient controlled in the range of 12-18 N / mm, which can not only ensure enough pushing force to accurately send the cut filter cloth 5 into the connecting pipe 38, but also avoid impurities splashing due to excessive spring force.

[0044] As shown in Figure 8 The outer wall of the collecting cylinder 9 is fixed with the collecting box 16 by welding, one of the collecting boxes 16 is located in the furnace body 11 and below the grate 37, and is used to receive the ash after burning. A sealing ring 10 coaxial with the rotating table 8 is fixed on one side of the furnace body 11, the sealing ring 10 is located above the collecting box 16 and can seal the remaining collecting boxes 16 at the same time to prevent ash leakage. In order to facilitate the removal of the collecting cylinder 9 from the rotating table 8, a rectangular port 14 is formed on one side of the sealing ring 10, a plug plate 15 is inserted into the rectangular port 14 in interference fit, and multiple collecting cylinders 9 are located in the sealing ring 10 and can be further fixed by the sealing ring 10 cooperating with the positioning groove 18. When it is necessary to clean the ash in the collecting box 16 or replace the collecting cylinder 9, the plug plate 15 can be pulled out of the rectangular port 14, at this time the collecting box 16 corresponds to the rectangular port 14, so that the top end of the collecting box 16 is opened, or the collecting cylinder 9 is removed from the rotating table 8.

[0045] During the experiment, the corresponding collection cylinder 9 can be moved to the lower side of the sliding pipe 22 according to the classification of the reagent. The adjustment step is to start the first motor 13 to rotate by the controller. The rotation of the first motor 13 can drive the rotating table 8 to rotate through the fixed shaft 12. During the rotation of the rotating table 8, the collection cylinder 9 can be moved through the positioning groove 18 and the plug rod 19. Until the collection cylinder 9 moves to the lower side of the sliding pipe 22, then the electric push rod 23 is started to extend. During the extension of the electric push rod 23, the pressing plate 20 can be moved downward, and during the downward movement of the pressing plate 20, the sliding pipe 22 can be moved downward, and the connecting frame 24 can drive the rack 25 to move downward. The downward movement of the filter cloth 5 can drive the rotating roller 26 to rotate through the friction between the gear 28, the rack 25 and the rotating roller 26, and the filter cloth 5 can be released. During the downward movement of the sliding pipe 22, the filter cloth 5 can be extruded to move downward. When the sliding pipe 22 moves into the collection cylinder 9, the filter cloth 5 can be folded through the cooperation of the cleaning block 35 on the conical head 33 and the abutting rod 36, so that the filter cloth 5 is in the shape of a petal cone.

[0046] The operator introduces the reagent into the water tank 2, and guides through the guide pipe 21 and the sliding pipe 22. When the reagent contacts the filter cloth 5, the filter cloth 5 can filter the reagent, and the filtered reagent can enter the collection cylinder 9. At the same time, the faucet 3 is opened for flushing, and the waste water of the flushing can flow into the collection cylinder 9 together.

[0047] Then the electric push rod 23 is started to retract. During the retraction of the electric push rod 23, the pressing plate 20 can be moved upward, and the upward movement of the pressing plate 20 can drive the sliding pipe 22 to move upward, so that the rectangular groove 34 is away from the collection cylinder 9. The impurities filtered out can be left on the filter cloth 5. During the upward movement of the conical head 33, the elastic rod 32 and the cleaning block 35 can clean the impurities on the inner wall. At the same time, the rack 25 and the gear 28 can drive the rotating roller 26 to rotate reversely, and the excess filter cloth 5 can be stored.

[0048] When used again, the second motor 27 is started to drive the rotating roller 26 on one side to rotate to store the filter cloth 5. Because the rotating roller 26 in the gear 28 is driven by resistance, when the rotating roller 26 on one side of the second motor 27 rotates, the rotating roller 26 in the gear 28 will not be stuck with the gear 28, so that it can drive the filter cloth 5 to move, so that the impurities left on the filter cloth 5 can move to the upper side of the cutter 39. When the electric push rod 23 is started to extend for filtering again, the filter cloth 5 can abut against the top rod 29 to move upward. After the cutter 39 cooperates with the groove 31 to cut the filter cloth 5 below the impurities, the top rod 29 can be reset and moved under the action of the spring 30, so as to push the cut filter cloth 5 into the connecting pipe 38 and fall on the grate 37. Then the burner 40 is started to burn, and the ash after burning can fall into the corresponding collection box 16.

[0049] When the collecting cylinder 9 needs to be taken out for replacement, the first motor 13 is started to drive the collecting cylinder 9 to move to one side of the rectangular opening 14, then the plug plate 15 is pulled out, and then the collecting cylinder 9 and the collecting box 16 are taken out for cleaning and replacement.

[0050] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions, and all should be covered in the scope of the claims of the present application.
