Description

Technical Field

[0001] The present invention relates to the technical field of fluidity testing, in particular to a fluidity testing device for chemical products. Background Art

[0002] Flowability testing is an experimental method used to evaluate the flow ability of a material under specific conditions. It reflects the flow characteristics of a material through quantitative indicators or direct observation. It is intended to help researchers or production personnel understand the material's processing performance, quality stability, and behavioral surface in actual applications.

[0003] When testing the flowability of chemical products such as chemical powders or granules, a powder property tester is usually used, such as the JL-A3 powder property tester. This tester evaluates the flowability of the chemical powder by pouring a specified amount of chemical powder or granules into a funnel and then measuring the time it takes for the chemical powder to fall from the funnel into a measuring container.

[0004] When using this testing instrument, you need to first use a measuring cup to weigh out a specified number of grams of the chemical powder to be tested, and then pour the chemical powder into the funnel through the measuring cup. During this process, some wet or sticky chemical powder will stick to the measuring cup, and you need to use a brush to clean the chemical powder into the funnel. However, during the cleaning process, the chemical powder will adhere to the brush, which will result in insufficient amount of chemical powder actually entering the funnel, which will cause errors in the fluidity test. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a fluidity testing device for chemical products, which solves the problems raised in the above-mentioned background technology.

[0006] The present invention provides the following technical solution: a fluidity testing device for chemical products, comprising a base, a support column fixed to the top of the base, limiting frames fixed to both sides of the top of the base, and a first lead screw and a second lead screw rotatably connected to the bottoms of the inner cavities of the two limiting frames, respectively;

[0007] An adjustment plate is threaded on the surface of the first lead screw, a motor is fixed on the surface of the adjustment plate, a clamping ring is fixed on the output shaft of the motor, and an extension rod is fixed on the top of the clamping ring;

[0008] The surface of the support column is slidably connected to a support plate, and the interior of one end of the support plate is slidably connected to a Z-shaped plate, and the Z-shaped plate is composed of an upper horizontal plate, a vertical plate and a lower horizontal plate. A spring is fixed to the top of one end of the support plate, and the spring is fixed to the upper horizontal plate of the Z-shaped plate, a touch rod is fixed to the side of the vertical plate of the Z-shaped plate away from the spring, and an airbag cushion is fixed to the bottom of the horizontal plate under the spring.

[0009] Optionally, a main bracket is slidably connected to the surface of the support column, a detection plate is fixed to one end of the main bracket close to the extension rod, and a camera is fixed inside the main bracket close to the detection plate.

[0010] Optionally, the surface of the support column is located above the main bracket and is slidably connected to a sub-bracket. A fixing ring is fixed to one end of the sub-bracket close to the detection disk. The interior of the fixing ring is rotatably connected to a rotating shaft. A sealing plate is fixed to the bottom of the rotating shaft. A paddle plate is fixed to one side of the sealing plate. A funnel is clamped inside the fixing ring.

[0011] Optionally, a locking screw is connected to the internal thread of one side of the clamping ring.

[0012] Optionally, a locking bolt is connected to the internal thread of the support plate away from the Z-shaped plate.

[0013] Optionally, a triangular baffle is fixed to the top of the lower horizontal plate of the Z-shaped plate, and an exhaust hole is opened on the surface of the bottom of the airbag cushion.

[0014] Optionally, a lifting bracket is threadedly connected to the surface of the second screw, and a sliding groove is provided inside the lifting bracket.

[0015] Optionally, the internal sliding connection of the slide groove is provided with a threaded rod, a connecting plate is fixed to the top of the threaded rod, a gasket is fixed to one end of the connecting plate, an elastic cloth is fixed to the top of the gasket, a spiral frame is fixed to the outside of the elastic cloth at the top of the gasket, and the elastic cloth and the spiral frame are fixed, and a top ring is fixed to the top of the elastic cloth.

[0016] Optionally, a magnetic ring is inlaid on the surface of the backing ring, and an annular electromagnet is inlaid on the surface of the top ring, and the magnetic properties of the magnetic ring and the annular electromagnet are the same.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This fluidity testing device for chemical products places a measuring cup inside a clamping ring, controls the motor to start, drives the clamping ring and the extension rod to flip, and then pours the chemical powder into the funnel. During the flipping process, the extension rod touches the touch rod. Under the action of the touch rod and the spring, the extension rod and the clamping ring vibrate repeatedly, and then the measuring cup vibrates repeatedly, so that the chemical powder in the measuring cup is poured into the funnel in full, thereby improving the accuracy of the fluidity test.

[0019] 2. The fluidity testing device for chemical products starts the annular electromagnet before the funnel dumps the chemical powder, so that the magnetic ring repels the annular electromagnet. After the annular electromagnet is repelled, it carries the top ring and fits against the bottom of the sealing plate. When the sealing plate rotates away from the bottom of the funnel, the annular electromagnet fits against the outside of the bottom of the funnel. At the same time, the annular electromagnet carries the top ring to stretch the spiral frame and elastic cloth, so that the elastic cloth stretches to form a windproof cover, ensuring the stability of the chemical powder tilting, reducing the probability of the chemical powder dumping being offset due to external airflow, and thereby improving the accuracy of testing the fluidity of the chemical powder.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] See also Figure 1-8 A fluidity testing device for chemical products includes a base 1, with limiting frames 3 fixed on both sides of the top of the base 1. The bottoms of the inner cavities of the two limiting frames 3 are rotatably connected to a first screw 31 and a second screw 32, respectively. The surface of the first screw 31 is threaded with an adjustment plate 33, and the surface of the adjustment plate 33 is fixed with a motor 34. The output shaft of the motor 34 is fixed with a clamping ring 35, and the top of the clamping ring 35 is fixed with an extension rod 36;

[0032] The surface of the support column 11 is slidably connected to the support plate 4, and the interior of one end of the support plate 4 is slidably connected to a Z-shaped plate 41. The Z-shaped plate 41 consists of an upper horizontal plate, a vertical plate, and a lower horizontal plate. A spring 42 is fixed to the top of one end of the support plate 4, and the spring 42 is fixed to the upper horizontal plate of the Z-shaped plate 41. A touch rod 43 is fixed to the side of the vertical plate of the Z-shaped plate 41 away from the spring 42, and an airbag cushion 44 is fixed to the bottom of the horizontal plate below the spring 42.

[0033] A support column 11 is fixed to the top of the base 1, and a main bracket 2 is slidably connected to the surface of the support column 11. A detection disk 21 is fixed to the end of the main bracket 2 close to the extension rod 36, and a camera 22 is fixed to the inside of the main bracket 2 close to the detection disk 21. A sub-bracket 23 is slidably connected to the surface of the support column 11 above the main bracket 2, and a fixing ring 24 is fixed to the end of the sub-bracket 23 close to the detection disk 21. A rotating shaft 25 is rotatably connected to the inside of the fixing ring 24, and a sealing plate 26 is fixed to the bottom of the rotating shaft 25. A dial plate 261 is fixed to one side of the sealing plate 26. A funnel 27 is clamped inside the fixing ring 24, and a locking screw 351 is connected to the internal thread of the clamping ring 35. A locking bolt 401 is connected to the internal thread of the support plate 4 away from the Z-shaped plate 41;

[0034] During the specific operation, first adjust the main bracket 2, the auxiliary bracket 23, and the adjustment plate 33 to an appropriate height, then pour the chemical powder into the measuring cup and weigh it with an electronic scale, then obtain the specified number of grams of the chemical powder to be tested, and then pour the chemical powder into the funnel 27, and then start the flowability test and measurement evaluation. This is the step of testing the powder flow rate of the powder property tester in the prior art, and the present invention will not be repeated in detail;

[0035] Specifically, in actual operation, after the height adjustment of the main bracket 2, the auxiliary bracket 23, and the adjustment plate 33 is completed, the height of the support plate 4 is adjusted accordingly, and the support plate 4 is fixed at a specified height by the locking bolt 401, so that the height of the support plate 4 is adapted to the main bracket 2, the auxiliary bracket 23, the adjustment plate 33, and the measuring cup. After the specified number of grams of chemical powder is weighed into the measuring cup, the measuring cup is placed inside the clamping ring 35 and fixed inside the clamping ring 35 by the locking screw 351.

[0036] Then, the controller starts the motor 34, which drives the clamping ring 35 to flip clockwise. The clamping ring 35 drives the measuring cup to flip clockwise. During the clockwise flipping process, the cup mouth gradually tilts toward the funnel 27 until the chemical powder in the measuring cup is poured into the funnel 27. When the measuring cup flips clockwise, the clamping ring 35 simultaneously drives the extension rod 36 to flip clockwise. During the flipping process, the extension rod 36 gradually approaches the touch rod 43 until the extension rod 36 contacts the touch rod 43.

[0037] When the extension rod 36 contacts the touch rod 43, the motor 34 can be controlled to rotate slightly and repeatedly forward and reverse, so that the clamping ring 35 drives the extension rod 36 to contact the touch rod 43 slightly and repeatedly, and then the extension rod 36 and the touch rod 43 vibrate against each other, so that the extension rod 36 drives the clamping ring 35 to vibrate, and the clamping ring 35 drives the measuring cup to vibrate. The vibration of the measuring cup increases the speed of dumping the chemical powder in the measuring cup. At the same time, the chemical powder adhering to the measuring cup due to its own humidity or viscosity can also be shaken off into the interior of the funnel 27, so that the measuring cup can dump the chemical powder into the interior of the funnel 27 in full, thereby improving the accuracy of the test when the funnel 27 subsequently dumps the chemical powder.

[0038] After the chemical powder is completely poured into the funnel 27, the dial plate 261 can be pushed outward, causing the dial plate 261 to drive the sealing plate 26 and the rotating shaft 25 to rotate. As the sealing plate 26 rotates, the sealing plate 26 loses its blockage on the funnel 27, and the chemical powder in the funnel 27 falls toward the measuring container below. When the chemical powder falls into the interior of the detection plate 21, the camera 22 takes a picture of the chemical powder and records the falling time of the chemical powder.

[0039] Furthermore, while the funnel 27 is tilting the chemical powder, the motor 34 can be controlled to rotate slightly forward and reverse repeatedly, so that the clamping ring 35 drives the extension rod 36 to repeatedly squeeze the Z-shaped plate 41. The Z-shaped plate 41 is subjected to the pressure of the pressure extension rod 36 and the return force of the spring 42, and slides up and down repeatedly inside the support plate 4. During the downward movement of the Z-shaped plate 41, the airbag cushion 44 is synchronously pressed downward, so that the airbag cushion 44 repeatedly contacts the top of the funnel 27, thereby repeatedly knocking the funnel 27.

[0040] By repeatedly tapping the funnel 27, the outlet below the funnel 27 is prevented from being blocked by chemical powder, and the smoothness of the chemical powder tilting of the funnel 27 is improved, making the stopwatch and camera 22 shooting and timing more accurate. At the same time, by repeatedly tapping the funnel 27, the chemical powder is prevented from adhering to the surface of the funnel 27 due to its own moisture or stickiness, so that the chemical powder can fully participate in the fluidity test of the entire powder, thereby improving the accuracy of the chemical powder fluidity test.

[0041] It should be noted that all the electronic control devices of the present invention are controlled by a controller, and bolts are provided inside the main bracket 2, the auxiliary bracket 23 and the fixing ring 24. The main bracket 2 and the auxiliary bracket 23 can be fixed at a specified height on the surface of the support column 11 by bolts, and the detection plate 21 can fix the funnel 27 by bolts.

[0042] Example 2:

[0043] A triangular baffle 5 is fixed to the top of the lower horizontal plate of the Z-shaped plate 41, and an exhaust hole 6 is opened on the surface of the bottom of the airbag cushion 44;

[0044] Specifically, based on the first embodiment, when the funnel 27 is dumping the chemical powder, the clamping ring 35 drives the extension rod 36 to repeatedly and slightly squeeze the Z-shaped plate 41, causing the Z-shaped plate 41 to repeatedly slide up and down inside the support plate 4. The Z-shaped plate 41 drives the airbag cushion 44 to repeatedly strike the funnel 27, thereby vibrating the funnel 27 and improving the smoothness and integrity of the chemical powder dumping by the funnel 27.

[0045] During actual operation, when the airbag cushion 44 hits the funnel 27, since the funnel 27 is fixed inside the fixing ring 24, when the airbag cushion 44 hits the funnel 27, the resistance of the funnel 27 causes the airbag cushion 44 to be compressed. During the compression process, the air inside the airbag cushion 44 is compressed and blown out through the exhaust hole 6. The exhaust hole 6 is located above the funnel 27, and then the air in the airbag cushion 44 is blown toward the funnel 27 through the exhaust hole 6. The chemical powder adhered to the surface of the funnel 27, based on the vibration of the funnel 27 and the blowing of the airbag cushion 44, further falls into the measuring container below, further improving the efficiency of the falling of the adhered chemical powder, and once again improving the integrity of the chemical powder dumping from the funnel 27, thereby allowing the subsequent stopwatch and camera 22 to test a sufficient amount of chemical powder.

[0046] It should be noted that before testing the present invention, the motor 34 needs to be debugged to ensure that the flipping angle of the motor 34 can enable the clamping ring 35 to drive the extension rod 36 to stably press the Z-type plate 41, and then the Z-type plate 41 stably presses the airbag cushion 44 to shrink, thereby achieving the effect of blowing. When the motor 34 rotates forward and reverse, such as when the forward rotation is clockwise, the motor 34 drives the Z-type plate 41 to press the airbag cushion 44, and when the reverse rotation is counterclockwise, the motor 34 drives the extension rod 36 to maintain contact with the Z-type plate 41 and gradually reduces the pressure on the Z-type plate 41, so that the Z-type plate 41 is slowly reset under the action of the spring 42, and then the airbag cushion 44 is slowly reset, thereby avoiding the airbag cushion 44 from sucking chemical powder into the interior of the airbag cushion 44 when resetting.

[0047] Example 3:

[0048] The surface of the second lead screw 32 is threadedly connected to the lifting bracket 7, and a sliding groove 71 is provided inside the lifting bracket 7. The interior of the sliding groove 71 is slidably connected to the threaded rod 8. A connecting plate 81 is fixed to the top of the threaded rod 8. A backing ring 82 is fixed to one end of the connecting plate 81. An elastic cloth 84 is fixed to the top of the backing ring 82. A spiral frame 85 is fixed to the top of the backing ring 82, which is located outside the elastic cloth 84. The elastic cloth 84 and the spiral frame 85 are fixed. A top ring 86 is fixed to the top of the elastic cloth 84. A magnetic ring 83 is inlaid on the surface of the backing ring 82. An annular electromagnet 87 is inlaid on the surface of the top ring 86. The magnetic properties of the magnetic ring 83 and the annular electromagnet 87 are the same.

[0049] Specifically, on the basis of the first and second embodiments, before the dial plate 261 is toggled, that is, when the outlet below the funnel 27 is still blocked by the sealing plate 26, the connecting plate 81 can be pushed so that the connecting plate 81 drives the threaded rod 8 to slide inside the slide groove 71 until the threaded rod 8 slides to the end of the slide groove 71 close to the detection disk 21. At this time, the threaded rod 8 slides to the maximum stroke, so that the connecting plate 81 drives the gasket 82 to slide above the lifting bracket 7, so that the gasket 82 moves to the top of the detection disk 21 and is located below the sealing plate 26. That is, after the threaded rod 8 slides to the maximum stroke, the gasket 82 is located directly above the detection disk 21 and directly below the sealing plate 26.

[0050] Subsequently, the controller activates the annular electromagnet 87, causing it to generate magnetism after being energized. The magnetism of the annular electromagnet 87 is the same as that of the magnetic ring 83, thereby releasing the attraction of the magnetic ring 83 to the annular electromagnet 87. As a result, the force relationship between the magnetic ring 83 and the annular electromagnet 87 changes from attraction to repulsion. At the same time, under the relaxation of the elastic cloth 84, the annular electromagnet 87 drives the top ring 86 and pulls the elastic cloth 84 and the spiral frame 85 to extend, so that the elastic cloth 84 can extend toward the sealing plate 26 until the top ring 86 is in contact with the sealing plate 26.

[0051] Subsequently, when the paddle 261 is toggled, the paddle 261 drives the sealing plate 26 to flip over and separate from the bottom of the funnel 27, thereby releasing the blockage of the outlet below the funnel 27. At the same time, after the sealing plate 26 rotates away from the bottom of the funnel 27, the top ring 86 and the annular electromagnet 87 are no longer restricted by the sealing plate 26. Under the condition that the magnetic ring 83 and the annular electromagnet 87 repel each other, the elastic fabric 84 and the spiral frame 85 are further stretched, so that the annular electromagnet 87 fits the outside of the bottom of the funnel 27.

[0052] Then, a wind shield is formed under the funnel 27 by the elastic cloth 84, and the wind shield is supported by the spiral frame 85. This ensures that when the funnel 27 is dumping the chemical powder, it is protected from external wind or ambient airflow, such as the wind generated by people walking, and prevents the flow trajectory of the chemical powder from deviating, thereby improving the accuracy of subsequent testing of the chemical powder flowability.

[0053] Furthermore, when the annular electromagnet 87 is continuously energized, the magnetic ring 83 continuously generates a repulsive thrust on the annular electromagnet 87, so that the annular electromagnet 87 is stably attached to the exterior of the lower portion of the funnel 27. When the annular electromagnet 87 is continuously energized, the heat generated by its operation is directly transferred to the exterior of the lower portion of the funnel 27, thereby increasing the temperature below the funnel 27, i.e., near the outlet of the funnel 27. The heated funnel 27 then reduces the viscosity and moisture of the chemical powder, thereby reducing the probability of chemical powder sticking together at the outlet of the funnel 27.

[0054] At the same time, on the basis of heating, in conjunction with the knocking and blowing of the funnel 27 in Example 1 and Example 2, the connection relationship between the powder particles is further destroyed, and the probability of sticky or moist chemical powder forming a bridge at the outlet of the funnel 27 is reduced, thereby ensuring the stability of the flow at the outlet of the funnel 27. The stability of the dumping flow of the funnel 27 further reduces the flow rate difference between the chemical powders tested each time, thereby reducing the error of each test result, making the average value of the test result more accurate.

[0055] It should be noted that the annular electromagnet 87 is made of metal material. When the annular electromagnet 87 is not energized, it can be adsorbed by the magnetic ring 83, and the top ring 86 is made to fit with the gasket ring 82, thereby compressing the elastic cloth 84 and the spiral frame 85, so that the elastic cloth 84 and the spiral frame 85 are in a contracted state. After the elastic cloth 84 is extended, the spiral frame 85 serves as a frame to support the elastic cloth 84, and the spiral frame 85 is made of elastic rubber material.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
