Description

Technical Field

[0001] This invention relates to mineral wettability measurement technology, belonging to the field of measurement, and specifically to a device for measuring the wettability of small-diameter mineral particles and its usage method. Background Technology

[0002] Particle wettability refers to the ability or tendency of a liquid to spread on a solid surface. It is involved in many fields, such as mineral and coal sorting, petroleum industry, materials, powdered pharmaceuticals, cosmetics, etc. In the field of mineral processing engineering, particle wettability reflects the ability of particles to be wetted.

[0003] In actual mineral particle transportation, open-air conveying systems are often used. For example, conveying and unloading devices allow mineral particles to be transported and stacked or unloaded during movement. In this process, the particles are in direct contact with the atmosphere, leading to the large-scale diffusion of tiny particles and pollution of the surrounding environment. In severe cases, this can even trigger coal dust explosions. Spray dust suppression technology, by increasing the moisture content of mineral particles, can effectively suppress the formation of suspended particles. This is one of the most efficient dust suppression methods in integrated mining faces. Therefore, understanding the wettability of particles is crucial for spray dust suppression and particle flotation.

[0004] Current methods for measuring particle wettability commonly employ the wetting angle method and microcalorimetry. These two methods are complex to operate, have high requirements for experimental operation and sample preparation, can only measure the wettability of a single point on the mineral, and cannot control temperature and humidity, which may lead to certain deviations in the measurement results. Summary of the Invention

It has a simple and compact structure, which not only enables the control of temperature and humidity and reduces the influence of the external environment, but also measures the wettability of multiple groups of particles and records the wettability effect of the particles in real time.

[0006] To achieve the above objectives, a device for measuring the wettability of small-diameter mineral particles is provided, comprising:

[0008] The measuring mechanism consists of multiple sets, which are located correspondingly between adjacent grids and between the inner wall of the measuring box and the adjacent grids. Each set of measuring mechanisms includes a transparent measuring tube arranged vertically and a water-absorbing net that is sealed at the lower end of the measuring tube and lower than the grid. Sensors are arranged vertically and horizontally on the measuring tube.

[0012] The interface of the water outlet pipe on the measuring box is lower than the interface of the water inlet pipe thereon.

[0013] Further, the water baffle is vertically arranged near the water inlet pipe of the measuring box.

[0014] The lower end of the water baffle is sealingly connected with the measuring box, and the upper end is higher than the water absorption net.

[0015] Further, along the direction from the water inlet to the water outlet, the diameters of the plurality of measuring pipes gradually decrease, and the diameter of the water absorption net correspondingly decreases.

[0016] Further, the measuring pipe is provided with a scale in the same direction.

[0017] Further, the constant temperature mechanism has a refrigeration assembly and a heating assembly which are both connected with the controller and controlled.

[0018] The input ends of the refrigeration assembly and the heating assembly are both horizontally attached in the measuring box.

[0019] The measuring box is provided with a temperature sensor.

[0020] Further, the heat preservation door is provided with heat preservation materials on the side, double-layer glass in the middle position, and a vacuum structure formed between them.

[0021] The heat preservation door is provided with a lamp strip on the inner side of the measuring box, and a magnetic block in sealing contact with the measuring box.

[0022] Further, the grid is provided with a rectangular grid with a length of 72.5 cm and a width of 30 mm, and each grid is 184 mm apart.

[0023] The purpose of the present application is also to provide a method for using a small particle size mineral particle wettability measuring device, a constant temperature mechanism capable of keeping the temperature and humidity in the measuring box unchanged, reducing the influence of the external environment, placing the measuring mechanism in the measuring box, realizing real-time recording of the wettability effect of the particles in the measuring pipe, and collecting corresponding data, which is more convenient for processing.

[0024] Not only to achieve the control of temperature and humidity, reduce the influence of the external environment, but also can measure the wetting of multiple groups of particles, real-time record the effect of particle wetting, processing is more convenient.

[0025] A method for using a small particle size mineral particle wetting measurement device, specifically comprising the following steps:

[0026] a. Start the constant temperature mechanism, so that the temperature in the measurement box is maintained within a certain range;

[0027] b. Use the tape to seal the water absorption net, add the test particles to the measurement tube, and oscillate multiple times to make the particle height reach the test height;

[0028] c. Remove the tape on the water absorption net, place the measurement tube vertically in the measurement box through the support frame, and make the water absorption net at the lower end of the measurement tube lower than the grid and higher than the bottom end of the measurement box; when multiple measurement mechanisms are tested, different measurement tubes can be placed in adjacent grids and between the inner wall of the measurement box and the adjacent grid;

[0029] Close the measurement box, place the industrial camera on one side of the measurement box, and adjust the corresponding height to make it align with the measurement tube;

[0030] d. The water in the filter box is first introduced into the cavity between the measurement box and the water baffle through the water inlet pipe, and then gradually immersed in the water absorption net after overflowing, and finally returned to the filter box through the water outlet pipe;

[0033] Compared with the prior art, the small particle size mineral particle wetting measurement device places the measurement mechanism in a closed measurement box, the constant temperature mechanism can keep the temperature and humidity in the measurement box unchanged, reduce the influence of the external environment, and introduce the water in the filter box into the measurement box and above the water absorption net. Not only can multiple groups of particles be measured, but also the wetting effect of the particles in the measurement tube can be recorded in real time, and the corresponding data can be collected. The structure is simple and compact, and the processing is more convenient;

[0034] Since the water in the filter box is first introduced into the cavity between the measuring box and the water baffle from the water inlet pipe, and then the overflow water gradually immerses the water absorption net, and finally returns to the filter box from the water outlet pipe, on the one hand, the cavity reduces the impact of the water flow entering, and the overflow water gradually immerses the corresponding water absorption net, avoiding the measurement deviation of the particle wettability in the measuring pipe caused by the splashing of the water flow, on the other hand, the water circulation is realized, and the water in the measuring box is kept in a stable dynamic and clean state.

[0035] Since the diameters of the plurality of measuring pipes gradually decrease along the water inlet to water outlet direction, the measuring mechanism can realize the measurement of the wettability of the particles in measuring pipes with different diameters in the same environment, facilitating comparison.

[0046] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0047] As shown in Figures 1 to 4 , Figure 6 The small-particle mineral particle wettability measuring device comprises:

[0048] The measuring box 20 is sealed and located above the support platform 10, and a plurality of grids 50 are arranged at intervals in the measuring box 20 to separate the measuring box 20. The side is provided with a constant temperature mechanism 70, and the outside is provided with an industrial camera 80 capable of shooting the inside of the measuring box 20. Each grid 50 has a distance from the lower end of the measuring box 20 to the bottom end of the measuring box 20;

[0049] The measuring mechanism 60 is a plurality of groups and is located between the adjacent grids 50 and the inner wall of the measuring box 20 and the adjacent grids 50. Each group of measuring mechanisms 60 comprises a transparent and vertically arranged measuring tube 61 and a water absorption net 62 sealed at the lower end of the measuring tube 61 and below the grid 50. The measuring tube 61 is provided with sensors 41 arranged at intervals.

[0050] The filter box 30 is located below the support platform 10, and water is introduced into the measuring box 20 and is higher than the water absorption net 62;

[0051] Specifically, the support platform 10 is a support structure of the device, and the lower end can be located on a movable support, such as being fixed by a plurality of guide columns, each guide column having a roller with a foot brake function at the lower end. The measuring box 20 has good overall sealing and can use high-density glass fiber insulation material. Each grid 50 is vertically arranged and has a distance from the bottom end of the measuring box 20, so that a passage is formed at the lower end of the measuring box 20. The CCD industrial camera 80 can record the internal conditions of the measuring box 20 in real time.

[0052] According to the requirements, different numbers of measuring mechanisms 60 can be selected, and the measuring mechanisms 60 are placed in the measuring box 20, as shown in Figure 6 The measuring tube 61 is detachably mounted on the support frame 63, the support frame 63 is located in the measuring box 20 through four corner supports, the water absorption net 62 is a cylindrical structure and is provided with a rectangular hole with a size of 1.2-1.2 mm, the water absorption net 62 is coaxially connected with the measuring tube 61, and the connection part can be coated with sealing glue. The measuring tube 61 can be made of acrylic pipe, and small holes with a diameter of 6 mm are arranged at intervals of 50 mm on the pipe wall. The filter box 30 itself is a container capable of containing a certain amount of water, and a filtering and impurity removing assembly can be arranged inside the filter box 30, or a filter is arranged at the output end of the filter box 30 to keep the water clean.

[0053] The sensor 41 on the measuring tube 61 is a temperature and humidity sensor. The vertical spacing of the sensor 41 can be 5cm, which can detect the temperature and humidity at different heights on the measuring tube 61. The adjacent grid 50 can be provided with a wiring mechanism corresponding to the sensor 41, or the sensor 41 on the same measuring tube 61 can be connected to the bus first, and then connected to the wiring mechanism on the grid 50 through the bus. This can ensure that the measuring mechanism 60 connects to the docking sensor 41 when it is put in and taken out, and ensure the use of the sensor 41.

[0054] To better illustrate, Figure 2 In the middle, the filter box 30 introduces water from the left and discharges it from the right, and the measuring box 20 is used for explanation;

[0055] When this small-diameter mineral particle wettability measuring device is in operation, the first step is to prepare the feed, that is, to start the constant temperature mechanism 70 so that the temperature inside the measuring chamber 20 is maintained within a certain range, such as the deviation is within 5℃, and to check the working status of each component.

[0056] Use tape to seal the absorbent net 62 to prevent water from entering the absorbent net 62 before measurement and to prevent a small number of particles from leaking out of the absorbent net 62 during vibration; add test particles to the measuring tube 61 and vibrate it several times until the particle height reaches the test height. This is to reduce the particle gap and avoid the particle gap in the measuring tube 61 being too large and affecting the measurement results. For example, you can first add particles to a height of 25cm in the measuring tube 61, vibrate it several times, then add particles to 50cm and vibrate it several times. Then add more particles until the particles are stable at a height of 50cm.

[0057] Remove the tape from the absorbent net 62 and place the measuring tube 61 into the measuring chamber 20. For example, the measuring tube 61 can be mounted on the support frame 63, which is placed inside the measuring chamber 20, ensuring that the absorbent net 62 at the lower end of the measuring tube 61 is lower than the grid 50. When testing multiple measuring mechanisms 60, different measuring tubes 61 can be placed between adjacent grids 50. Place the industrial camera 80 on one side of the measuring chamber 20 and adjust it to the appropriate height so that the industrial camera 80 can capture the rising height of the particles inside the measuring tube 61.

[0058] Water is introduced from the filter box 30 into the measuring box 20 and gradually rises above the water absorption net 62. The water enters the water absorption net 62 and reaches the measuring tube 61, wetting the particles inside and gradually rising until the particles stop rising.

[0059] Multiple tests were conducted using the same measuring mechanism 60, such as 3-5 measurements, to obtain multiple sets of data on the height of particle rise. The mean and variance of the data were then analyzed to obtain the measurement results.

[0060] The small particle size mineral particle wettability measuring device, the measuring mechanism 60 is placed in the closed measuring box 20, the constant temperature mechanism 70 can keep the temperature and humidity in the measuring box 20 unchanged, reduce the influence of external environment, the water in the filter box 30 is connected to the measuring box 20 and higher than the water absorption net 62, the wettability effect of the particles in the measuring tube 61 is recorded in real time, and the corresponding data is collected, the structure is simple and compact, and the processing is more convenient;

[0061] In addition, the collected data can be imported into an analysis computer, and the actual measuring device is simulated by software, that is, a small particle size mineral particle wettability data fitting and image processing model is established, the wettability effect of the high particles, the maximum and minimum values of the wettability can be quickly calculated, and the wettability state of the particles can be judged; The data fitting part is to fit the data of completely wet particles to view the wetting rate; The image processing part can process the images taken in the experiment, and the images with better display effect are selected and exported.

[0062] As shown in Figure 3 In some improved schemes, the measuring box 20 is provided with a drain pipe 23, one side is connected with the filter box 30 through the water inlet pipe 31, and the other side is connected with the filter box 30 through the water outlet pipe 33, so that the water forms a loop;

[0064] The interface of the water outlet pipe 33 of the measuring box 20 is lower than that of the water inlet pipe 31 above it;

[0065] Specifically, the electromagnetic valve is used to open and close the water inlet pipe 31, and the drain pipe 23 is used to drain all the water in the measuring box 20; The pump body 32 is opened, the water in the filter box 30 enters the measuring box 20 from the water inlet pipe 31, the water absorption net 62 is soaked, and then the water flows back to the filter box 30 from the water outlet pipe 33, realizing the circulation of water and ensuring that the water in the measuring box 20 is in stable dynamic state; In addition, the electromagnetic valve and the pump body 32 are controlled by the controller 40, realizing the automatic control of the whole.

[0066] As shown in Figure 3 Further, the measuring box 20 is vertically provided with a water baffle 22 close to the water inlet pipe 31;

[0067] The lower end of the water baffle 22 is sealingly connected with the measuring box 20, and the upper end is higher than the water absorption net 62;

[0068] Specifically, the water baffle 22 and the left inner wall of the measuring box 20 form a cavity, and the water flow of the water inlet pipe 31 first enters the cavity, that is, the water flow in the cavity gradually enters the right side of the water baffle 22 after overflowing, and the purpose is to reduce the impact of the water flow entering through the cavity after the pump body 32 is started, and to gradually immerse the corresponding water absorption net 62 in the water overflow mode, so as to avoid the measurement deviation of the particle wettability in the measuring tube 61 caused by the splashing of the water flow.

[0069] In some improved schemes, along the water inlet to water outlet direction, the diameters of the plurality of measuring tubes 61 gradually decrease, and the diameters of the water absorption nets 62 correspondingly decrease;

[0070] Specifically, when the measuring mechanism 60 is four groups, the diameters of the measuring tubes 61 and the water absorption nets 62 at the lower ends thereof gradually decrease from left to right, for example, the diameters are 50mm, 40mm, 30mm and 10mm from left to right; The purpose of this mode is to enable the measuring mechanism 60 to measure the wettability of particles in measuring tubes 61 of different diameters in the same environment, facilitating comparison.

[0071] Further, the measuring tube 61 is provided with a scale 64 in the same direction;

[0072] The scale 64 effectively measures the lifting height after the water submerges the water absorption net 62, and the change of the particle wettability effect, facilitating the industrial camera 80 to collect data.

[0073] As shown in Figure 3 , Figure 4 In some improved schemes, the constant temperature mechanism 70 has a refrigeration assembly and a heating assembly which are both connected to and controlled by the controller 40;

[0074] The input ends of the refrigeration assembly and the heating assembly are both horizontally attached in the measuring box 20;

[0075] The measuring box 20 is provided with a temperature sensor;

[0076] Specifically, the refrigeration assembly and the heating assembly can be sealed on the measuring box 20, and the device further includes a display, that is, the display can be touch screen to set corresponding parameters, and when the temperature in the measuring box 20 is set, the controller 40 controls the refrigeration assembly and the heating assembly to adjust each other, so that the temperature in the measuring box 20 is maintained within a certain range.

[0077] As shown in Figure 5 In some improved schemes, the heat preservation door 21 is made of heat preservation material, the middle position is double-layer glass, and a vacuum structure is formed between them;

[0078] The heat preservation door 21 is provided with a lamp strip 25 on the inner side of the measuring box 20, and a magnetic block 24 which is in sealing contact with the measuring box 20;

[0079] Specifically, the double-layer glass on the heat preservation door 21 can guarantee that the industrial camera 80 can monitor the internal condition of the measuring box 20 in real time, the body is made of heat preservation material and vacuum heat insulation, and the magnetic block 24 can be adsorbed on the measuring box 20 when the heat preservation door 21 is closed, so as to keep the sealing property.

[0080] In some improved schemes, the grids 50 are arranged at equal intervals in a rectangular grid with a length of 72.5 cm and a width of 30 mm, and the distance between each grid 50 is 184 mm.

[0081] When the small-particle mineral particle wettability measuring device is used, the water absorption net 62 is first sealed, then the particles to be measured are added into the measuring tube 61, and the particles are stabilized at a certain height after multiple oscillations and supplement addition;

[0082] Then, the measuring tube 61 is placed in the measuring box 20, the position of the industrial camera 80 is adjusted to align with the measuring tube 61, the sealing of the water absorption net 62 is removed, the electromagnetic valve is opened and the pump body 32 is started, the water in the filtering box 30 is first introduced into the cavity between the measuring box 20 and the water baffle 22 from the water inlet pipe 31, and then the water overflowed gradually immerses the water absorption net 62, and finally flows back to the filtering box 30 from the water outlet pipe 33;

[0083] The water at the lower end of the measuring box 20 enters the measuring tube 61 from the water absorption net 62, rises and wets the particles, and the industrial camera 80 shoots the rising height of the water and the particles in the measuring tube 61 in real time, after multiple tests and measurements, the analysis computer obtains the data taking average method, and the measurement result of the particle wettability is obtained.
