Description

Technical Field

[0001] The present invention relates to the technical field of fluidity testing, and specifically relates to a fluidity testing device for chemical products. Background Technique

[0002] Fluidity testing is an experimental method used to evaluate the flow ability of materials under specific conditions. By quantifying indicators or direct observation, it reflects the flow characteristics of materials, aiming to help researchers or production personnel understand the processing performance, quality stability, and behavior surface in actual applications of materials.

[0003] When performing fluidity testing on chemical products such as chemical powders or granules, a comprehensive powder property tester is usually selected. For example, the powder property tester with the model JL-A3 is to pour a specified number of grams of chemical powder or granules into a funnel, and then evaluate the fluidity of the chemical powder according to the time it takes for the chemical powder to fall from the funnel into a measuring container; When using this testing instrument, it is necessary to first weigh a specified number of grams of the chemical powder to be tested with a measuring cup, and then pour the chemical powder from the measuring cup into the funnel. During this process, some wet or sticky chemical powders will adhere to the measuring cup, and it is necessary to use a brush to sweep the chemical powder into the funnel. However, during the sweeping process, the chemical powder will adhere to the brush, resulting in an insufficient amount of chemical powder actually entering the funnel, and thus causing errors in the fluidity testing. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a fluidity testing device for chemical products, which solves the problems raised in the above background technique.

[0005] The present invention provides the following technical solution: A fluidity testing device for chemical products, including a base, a support column is fixed on the top of the base, and limiting frames are respectively fixed on both sides of the top of the base. The bottoms of the inner cavities of the two limiting frames are respectively rotatably connected with a first lead screw and a second lead screw; A regulating plate is threaded on the surface of the first lead screw, a motor is fixed on the surface of the regulating 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; A support plate is slidably connected to the surface of the support column, a Z-shaped plate is slidably connected to the inside of one end of the support plate. The Z-shaped plate is composed of an upper cross plate, a vertical plate, and a lower cross plate. A spring is fixed on the top of one end of the support plate, and the spring is fixed to the upper cross plate of the Z-shaped plate. A touch rod is fixed on the side of the vertical plate of the Z-shaped plate away from the spring, and an airbag pad is fixed on the bottom of the lower cross plate of the spring.

[0006] Optionally, a main bracket is slidably connected to the surface of the support column. A detection disk is fixed to one end of the main bracket close to the extension rod, and a camera is fixed inside the main bracket on the side close to the detection disk.

[0007] Optionally, a secondary bracket is slidably connected above the main bracket on the surface of the support column. A fixing ring is fixed to one end of the secondary bracket close to the detection disk. A rotating shaft is rotatably connected inside the fixing ring. A sealing plate is fixed to the bottom of the rotating shaft. A dial is fixed to one side of the sealing plate. A funnel is clamped inside the fixing ring.

[0008] Optionally, a locking screw is threadedly connected inside one side of the clamping ring.

[0009] Optionally, a locking bolt is threadedly connected inside the support plate on the side away from the Z-shaped plate.

[0010] Optionally, a triangular baffle is fixed to the top of the lower horizontal plate of the Z-shaped plate, and exhaust holes are formed on the surface of the bottom of the airbag pad.

[0011] Optionally, a lifting bracket is threadedly connected to the surface of the second lead screw, and a sliding groove is formed inside the lifting bracket.

[0012] Optionally, a threaded rod is slidably connected inside the sliding groove. A connecting plate is fixed to the top of the threaded rod. A cushion ring is fixed to one end of the connecting plate. A elastic cloth is fixed to the top of the cushion ring. A spiral frame is fixed outside the elastic cloth at the top of the cushion ring, and the elastic cloth is fixed to the spiral frame. A top ring is fixed to the top of the elastic cloth.

[0013] Optionally, a magnetic ring is inlaid on the surface of the cushion ring, and an annular electromagnet is inlaid on the surface of the top ring, and the magnetic ring and the annular electromagnet have the same magnetism.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. For the fluidity testing device for chemical products, by placing the measuring cup inside the clamping ring, controlling the motor to start, driving the clamping ring and the extension rod to flip, and then pouring the chemical powder into the funnel. During the flipping process of the extension rod, it 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 fully poured into the funnel, thereby improving the accuracy of the fluidity test.

[0015] 2. Before the chemical powder is dumped from the funnel, the ring-shaped electromagnet is activated for the fluidity testing device for chemical products, so that the magnetic ring repels the ring-shaped electromagnet. After the ring-shaped electromagnet is repelled, it carries the top ring and fits against the bottom of the sealing plate. When the sealing plate turns away from the bottom of the funnel, the ring-shaped electromagnet then fits against the outside of the funnel below. At the same time, the ring-shaped electromagnet carries the top ring to stretch the spiral frame and the elastic cloth, so that the elastic cloth extends to form a wind shield, ensuring the stability of the inclination of the chemical powder and reducing the probability of the chemical powder being deflected during dumping due to external air flow. Furthermore, the accuracy of testing the fluidity of the chemical powder is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1:

[0020] Please refer to Figure 1-8 , a fluidity test device for chemical products, including a base 1. On both sides of the top of the base 1, limiting frames 3 are fixedly arranged. The bottoms of the inner cavities of the two limiting frames 3 are respectively rotatably connected with a first lead screw 31 and a second lead screw 32. A regulating plate 33 is threaded on the surface of the first lead screw 31. A motor 34 is fixedly arranged on the surface of the regulating plate 33. The output shaft of the motor 34 is fixedly connected with a clamping ring 35. An extension rod 36 is fixedly arranged on the top of the clamping ring 35; A support plate 4 is slidably connected to the surface of the support column 11. A Z-shaped plate 41 is slidably connected to the inside of one end of the support plate 4. The Z-shaped plate 41 is composed of an upper horizontal plate, a vertical plate and a lower horizontal plate. A spring 42 is fixedly arranged on the top of one end of the support plate 4, and the spring 42 is fixedly connected with the upper horizontal plate of the Z-shaped plate 41. A touch rod 43 is fixedly arranged on the side of the vertical plate of the Z-shaped plate 41 away from the spring 42. An airbag pad 44 is fixedly arranged on the bottom of the lower horizontal plate of the spring 42; A support column 11 is fixedly arranged on the top of the base 1. A main bracket 2 is slidably connected to the surface of the support column 11. A detection disc 21 is fixedly arranged at one end of the main bracket 2 close to the extension rod 36. A camera 22 is fixedly arranged inside the main bracket 2 on the side close to the detection disc 21. A secondary bracket 23 is slidably connected to the surface of the support column 11 above the main bracket 2. A fixing ring 24 is fixedly arranged at one end of the secondary bracket 23 close to the detection disc 21. A rotating shaft 25 is rotatably connected inside the fixing ring 24. A sealing plate 26 is fixedly arranged at the bottom of the rotating shaft 25. A dial 261 is fixedly arranged on one side of the sealing plate 26. A funnel 27 is clamped inside the fixing ring 24. A locking screw 351 is threaded inside one side of the clamping ring 35. A locking bolt 401 is threaded inside the side of the support plate 4 away from the Z-shaped plate 41; In the specific operation process, first, the main bracket 2, the secondary bracket 23, and the regulating plate 33 are adjusted to an appropriate height. Then, the chemical powder is poured into a measuring cup and weighed by an electronic scale. Subsequently, the specified grams of the chemical powder to be tested are obtained. Then, after the chemical powder is poured into the funnel 27, the fluidity test and metrological evaluation can be started. Here, it is the step of testing the powder flow rate by a powder property tester in the prior art, and the present invention will not elaborate on it in detail; Specifically, during the actual operation process, after the heights of the main support 2, the auxiliary support 23, and the adjusting plate 33 are adjusted, the height of the supporting plate 4 is correspondingly adjusted, and the supporting plate 4 is fixed at the specified height by the locking bolt 401, so that the height of the supporting plate 4 is adapted to the main support 2, the auxiliary support 23, the adjusting plate 33, and the measuring cup. After the chemical powder of the specified gram number is weighed in the measuring cup, the measuring cup is placed inside the clamping ring 35, and the measuring cup is fixed inside the clamping ring 35 by the locking screw 351; Then, the motor 34 is started through the controller, and the clamping ring 35 is driven by the motor 34 to rotate clockwise, so that the clamping ring 35 drives the measuring cup to rotate clockwise. During the clockwise rotation of the measuring cup, the cup mouth gradually tilts towards the funnel 27 until the chemical powder in the measuring cup is poured into the funnel 27. When the measuring cup rotates clockwise, the clamping ring 35 simultaneously drives the extension rod 36 to rotate clockwise, so that during the rotation of the extension rod 36, it gradually approaches the touch rod 43 until the extension rod 36 contacts the touch rod 43; After the extension rod 36 contacts the touch rod 43, the motor 34 can be controlled to rotate forward and backward slightly and repeatedly, 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 with 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 improves the dumping speed of 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 funnel 27, so that the measuring cup can pour the chemical powder into the funnel 27 in full quantity, thereby improving the accuracy of the subsequent chemical powder dumping test of the funnel 27; When the chemical powder is completely poured into the funnel 27, the dial 261 can be externally toggled, so that the dial 261 drives the sealing plate 26 and the rotating shaft 25 to rotate. As the sealing plate 26 rotates, the sealing plate 26 loses its blockage of the funnel 27, and then the chemical powder in the funnel 27 falls towards the lower measuring container. When the chemical powder falls into the inside of the detection plate 21, the chemical powder is photographed and recorded by the camera 22, and at the same time, the stopwatch is used to calculate the falling time of the chemical powder; Further, during the process of the funnel 27 tilting the chemical powder, the motor 34 can be continuously controlled to rotate forward and backward slightly and repeatedly, so that the clamping ring 35 drives the extension rod 36 to repeatedly press the Z-shaped plate 41. The Z-shaped plate 41 is subjected to the pressure of the extension rod 36 and the reset elastic force of the spring 42, and slides up and down repeatedly inside the supporting plate 4. When the Z-shaped plate 41 slides down, it drives the airbag pad 44 to press down synchronously, so that the airbag pad 44 repeatedly contacts the top of the funnel 27, thereby playing a role in repeatedly knocking the funnel 27; By repeatedly knocking on the funnel 27, blockage of the outlet below the funnel 27 by chemical powder is avoided, the fluidity of the chemical powder inclined by the funnel 27 is improved, and the stopwatch and the camera 22 can take pictures and time more accurately. At the same time, by repeatedly knocking on the funnel 27, adhesion of the chemical powder to the surface of the funnel 27 due to its own moisture or viscosity is avoided, so that the chemical powder can fully participate in the fluidity test of the whole powder, thereby improving the accuracy of the fluidity test of the chemical powder.

[0021] 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 sub-bracket 23 and the fixing ring 24. The main bracket 2 and the sub-bracket 23 can be fixed at a specified height on the surface of the support column 11 through the bolts, and the detection plate 21 can fix the funnel 27 through bolts.

[0022] Embodiment 2:

[0023] A triangular baffle 5 is fixed on the top of the lower cross plate of the Z-shaped plate 41, and exhaust holes 6 are formed on the surface of the bottom of the airbag pad 44; Specifically, on the basis of Embodiment 1, when the funnel 27 is discharging chemical powder, the clamping ring 35 drives the extension rod 36 to repeatedly and slightly squeeze the Z-shaped plate 41, so that the Z-shaped plate 41 repeatedly slides up and down inside the support plate 4, and the Z-shaped plate 41 drives the airbag pad 44 to repeatedly knock on the funnel 27, so as to vibrate the funnel 27 and improve the fluidity and discharge integrity of the chemical powder discharged by the funnel 27; During the actual operation, when the airbag pad 44 knocks on the funnel 27, since the funnel 27 is fixed inside the fixing ring 24, when the airbag pad 44 knocks on the funnel 27, the resistance of the funnel 27 causes the airbag pad 44 to be compressed. During the compression of the airbag pad 44, the air inside it is compressed and blown out through the exhaust holes 6. The exhaust holes 6 are located above the funnel 27. Then, the air in the airbag pad 44 is blown towards the funnel 27 through the exhaust holes 6, so that the chemical powder adhering to the surface of the funnel 27 further falls into the lower measuring container on the basis of the vibration of the funnel 27, in cooperation with the blowing of the airbag pad 44, further improving the falling efficiency of the adhering chemical powder and further improving the discharge integrity of the chemical powder by the funnel 27. As a result, the subsequent stopwatch and camera 22 can test a sufficient amount of chemical powder.

[0024] 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 can stably press the airbag cushion 44 to contract, thereby achieving the effect of blowing. When the motor 34 is rotating 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 the reverse rotation is counterclockwise. At this time, the motor 34 drives the extension rod 36 to maintain contact with the Z-type plate 41 and gradually reduce 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 inside of the airbag cushion 44 when it is reset.

[0025] Embodiment three:

[0026] The surface of the second lead screw 32 is threadedly connected with a lifting bracket 7, and a slide groove 71 is provided inside the lifting bracket 7. A threaded rod 8 is slidably connected inside the slide groove 71. A connecting plate 81 is fixed to the top of the threaded rod 8. A gasket 82 is fixed to one end of the connecting plate 81. An elastic cloth 84 is fixed to the top of the gasket 82. A spiral frame 85 is fixed to the top of the gasket 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 gasket 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. 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 one 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; Subsequently, the annular electromagnet 87 is started by the controller, so that the annular electromagnet 87 generates magnetism after being energized, and the magnetism of the annular electromagnet 87 is the same as that of the magnetic ring 83, and then the adsorption of the magnetic ring 83 on the annular electromagnet 87 is released, so that the force relationship between the magnetic ring 83 and the annular electromagnet 87 changes from adsorption 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 fits the sealing plate 26; Subsequently, when the dial plate 261 is toggled, the dial plate 261 drives the sealing plate 26 to flip, disengaging from the bottom of the funnel 27 and releasing the blockage of the outlet below the funnel 27. At the same time, after the sealing plate 26 turns away from the bottom of the funnel 27, the top ring 86 and the annular electromagnet 87 lose the limit of the sealing plate 26. Under the condition that the magnetic ring 83 and the annular electromagnet 87 repel each other, the elastic cloth 84 and the spiral frame 85 are further stretched, causing the annular electromagnet 87 to fit against the outside of the funnel 27 below; Subsequently, a wind shield is formed below the funnel 27 by the elastic cloth 84, and this wind shield is supported by the spiral frame 85 as a framework for the elastic cloth 84. This ensures that when the chemical powder is dumped from the funnel 27, external wind or environmental air currents, such as the wind generated by personnel movement, are avoided, preventing the flow trajectory of the chemical powder from shifting, and thus improving the accuracy of subsequent tests on the fluidity of the chemical powder; Furthermore, when the annular electromagnet 87 is continuously energized, the magnetic ring 83 continuously generates a repulsive thrust on the annular electromagnet 87, causing the annular electromagnet 87 to stably fit against the outside of the funnel 27 below. When the annular electromagnet 87 is continuously energized, the heat generated during its operation is directly transferred to the outside of the funnel 27 below, raising the temperature at the lower part of the funnel 27, that is, near the outlet of the funnel 27. Subsequently, the heated funnel 27 is used to reduce the viscosity and humidity of the chemical powder, thereby reducing the probability of the chemical powder sticking at the outlet of the funnel 27; At the same time, on the basis of heating, in combination with the knocking and blowing of the funnel 27 in the first and second embodiments, it further serves to break the connection relationship between the powder particles, reducing the probability of sticky or wet chemical powder forming a bridge at the outlet of the funnel 27. This ensures the stability of the flow rate at the outlet of the funnel 27. The stability of the dumping flow rate of the funnel 27 further reduces the flow rate difference between each test of the chemical powder, thereby reducing the error of each test result and making the average value of the obtained test results more accurate.

[0027] It should be noted that the annular electromagnet 87 is made of a metallic material. When the annular electromagnet 87 is not energized, it can be adsorbed by the magnetic ring 83, causing the top ring 86 to fit against the cushion ring 82, thereby compressing the elastic cloth 84 and the spiral frame 85, putting the elastic cloth 84 and the spiral frame 85 in a contracted state. After the elastic cloth 84 is extended, the spiral frame 85 serves as a framework to support the elastic cloth 84, and the spiral frame 85 is made of an elastic rubber material.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
