Description

Technical Field

[0001] The present invention relates to the technical field of coal-water slurry detection, and in particular to a coal-water slurry fluidity detector. Background Art

[0002] Coal-water slurry (CWS), a clean coal-based fuel, is made by mixing coal (60%-70%) with water (30%-40%) and a small amount of additives. It boasts high combustion efficiency and low pollutant emissions, making it widely used in industrial boilers, power plants, and the chemical industry. However, its performance is directly affected by key parameters such as concentration, particle size distribution, viscosity, and stability. Traditional detection methods (such as manual sampling and offline laboratory analysis) suffer from lag, large errors, and low efficiency.

[0003] In the patent named "Water-coal slurry fluidity tester" and the patent publication number CN119043990B, the prior art is proposed, through the design of U-shaped detection tube, laser pen, photosensitive receiver and electronic stopwatch, the time difference between the two groups of photosensitive receivers stopping receiving laser is displayed on the electronic stopwatch, and the fluidity of the water-coal slurry is displayed by this value. However, the flow rate of the water-coal slurry under different pressures is different, and the water-coal slurry contains impurities such as solid particles and iron filings, which can easily cause inaccurate detection. In addition, the water-coal slurry is extracted by two impellers with a constant speed to ensure that the pressure is fixed during extraction and transportation, and its Solid particles in the water-coal slurry are filtered to reduce inaccuracies in the detection process. However, during the fluidity test, the filter disc is fixed in position and will carry a large amount of impurities through the water-coal slurry. The shape and material of the impurities are also different. Some strip-shaped impurities are easily stuck inside the filter disc. When the strip-shaped impurities are stuck inside the filter, it is very easy to cause the filter disc to be blocked. When the filter disc is blocked, it is easy to cause changes in the suction pressure. Even if the two impellers are at a constant speed, the suction pressure is likely to be different. For this reason, a water-coal slurry fluidity tester is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0030] 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.

[0031] Example 1: Figure 1 As shown, the water-coal slurry fluidity tester of the present application comprises:

[0032] A detection barrel 101 is fixedly connected to an upper flange cover 102, to which a feeding structure is connected. A partition plate 111 is fixedly connected to the interior of the detection barrel 101, and a pressure detection chamber is formed between the partition plate 111 and the upper flange cover 102. A plurality of circulation channels 112 are connected below the partition plate 111, and a flow meter is installed inside each of the plurality of circulation channels 112;

[0033] The filter disc 113 is fixedly connected to the inside of the detection barrel 101. A plurality of square filter holes are provided on the outside of the filter disc 113. The filter disc 113 is connected to the feeding structure. The inside of the filter disc 113 is connected with an adjustment structure. The adjustment structure is connected to the square filter holes of the filter disc 113. The adjustment structure is used to control the opening and closing of the square filter holes of the filter disc 113.

[0034] Specifically, during use, after the water-coal slurry enters the pressure detection chamber, the water-coal slurry is continuously transported into the interior of multiple circulation channels 112 through external delivery pressure, and the fluidity of the water-coal slurry is monitored by the flow meters inside the multiple circulation channels 112. After the circulation channel 112 discharges the water-coal slurry, the water-coal slurry will fall onto the surface of the filter disc 113. The upper surface of the filter disc 113 presents a downwardly concave conical surface. When the water-coal slurry contacts the conical surface of the filter disc 113, it will gradually flow toward the center of the filter disc 113 due to the shape of the conical surface. When the water-coal slurry falls onto the filter disc 113, the square filter holes on the outside of the filter disc 113 can filter the water-coal slurry to reduce the presence of impurities.

[0035] like Figure 1-Figure 5 As shown, a secondary suction chamber is formed below the filter disc 113 and the inner bottom wall of the detection barrel 101. The bottom of the detection barrel 101 is connected to an annular tube 601, and multiple flow meters are installed inside the annular tube 601. The end of the annular tube 601 away from the detection barrel 101 is connected to a suction pump 602.

[0036] Specifically, after the water-coal slurry passes through the filter disc 113, it will enter the secondary suction chamber. After entering the secondary suction chamber, the water-coal slurry will be sucked into the annular tube 601 through the suction pump 602, and the fluidity of the water-coal slurry after filtration will be measured by multiple flow meters inside the annular tube 601.

[0037] like Figure 1-Figure 4As shown, an installation box 100 is installed on the outside of the detection barrel 101, and a central controller 109 is fixedly connected to the outside of the installation box 100. The detection ends of the central controller 109 are respectively connected to a first pressure sensor 110 and a second pressure sensor 600. The first pressure sensor 110 is located in the inlet pressure detection chamber, and the second pressure sensor 600 is located inside the secondary suction chamber. The outside of the filter disc 113 is connected to an outer heat-conducting cover 500, and the inner wall of the outer heat-conducting cover 500 is connected to multiple heating rods 501.

[0038] like Figures 1-9 As shown, the pushing structure includes an upper flange cover 102, which is fixedly connected to the detection barrel 101 through a flange, and the upper flange cover 102 is connected to a bearing cover 103, and the bearing cover 103 is respectively connected to a feed valve 104 and an air intake valve 105, the inlet of the feed valve 104 is connected to a feed pipe 106, and the inlet of the air intake valve 105 is connected to a first air supply pipe 107, and the end of the first air supply pipe 107 away from the air intake valve 105 is connected to an air pump 108, and the feed valve One end of the second air delivery pipe 114 away from the filter disc 113 passes through the outer wall of the upper flange cover 102 and is connected to a micro-electrically controlled valve 116. The outlet end of the micro-electrically controlled valve 116 is located inside the inlet pressure detection chamber. The end of the second air delivery pipe 114 away from the filter disc 113 passes through the outer wall of the upper flange cover 102 and the bearing cover 103 respectively and is connected to the inlet valve 105. The outer wall of the inlet valve 104 is connected to a diverter pipe 115, which passes through the outer wall of the upper flange cover 102 and is connected to the inlet pressure detection chamber.

[0039] Specifically, during use, the staff opens the feed valve 104. When the feed valve 104 is opened, the external water-coal slurry is injected into the interior of the feed valve 104 through the feed pipe 106, and is injected into the interior of the micro-electric control valve 116 through the feed valve 104. The micro-electric control valve 116 will then transport the water-coal slurry to the pressure detection chamber. When the water-coal slurry enters the pressure detection chamber, the air pump 108 is started to inject gas into the second gas pipe 114 and the diverter pipe 115. When the gas is injected into the diverter pipe 115, the diverter pipe 115 is opened. Tube 115 will transport the gas to the pressure detection chamber, and when the gas enters the pressure detection chamber, it will increase the pressure inside the pressure detection chamber, thereby accelerating the pushing of the water-coal slurry into the lower circulation channel 112. During the pushing, the internal pressure of the pressure detection chamber is detected in real time by the first pressure sensor 110, and when the water-coal slurry passes through the circulation channel 112 and the filter disc 113 and enters the secondary suction chamber, the suction force generated by the suction pump 602 inside the secondary suction chamber is detected by the second pressure sensor 600, thereby realizing dynamic adjustment as a whole.

[0040] Furthermore, when the water-coal slurry enters the interior of the secondary suction chamber, the central controller 109 is pushed to move by adjusting the structure, and the central controller 109 is pushed into the square filter hole. After the central controller 109 completely enters the square filter hole, the square filter hole can be sealed. After the square filter hole is sealed, the pressure transmitted from above will be cut off through the filter disc 113. In the case of cutoff, the pressure transmitted from the air pump 108 above will not affect the detection of the second pressure sensor 600 below.

[0041] Furthermore, after the internal space of the detection barrel 101 is divided by the filter disc 113 and the partition plate 119, the vertical fluidity of the water-coal slurry can be detected through the circulation channel 112 at the top, while the horizontal fluidity can be detected through the annular tube 601 at the bottom.

[0042] like Figure 3 and Figure 8 As shown, the second pressure sensor 600 is located inside the secondary suction chamber, the outside of the filter disc 113 is connected to the outer heat-conducting cover 500 , and the inner wall of the outer heat-conducting cover 500 is connected to multiple heating rods 501 .

[0043] Specifically, during the water-coal slurry fluidity test, the heating rod 501 can be started to generate heat. When the heating rod 501 generates heat, the heat will be transferred to the water-coal slurry through the outer heat-conducting cover 500, thereby avoiding the situation where the water-coal slurry cools down and the fluidity becomes worse, and the bottom of the heating rod 501 contacts the filter plate 113, thereby causing accumulation on the filter plate 113.

[0044] like Figure 1-Figure 7 As shown, the adjustment structure includes multiple movable grooves 117, which are connected to the square filter holes. A partition plate 119 is slidably connected inside the movable grooves 117, and the side of the partition plate 119 away from the square filter holes is connected to the diversion and conveying structure.

[0045] The diversion and conveying structure includes a second air pipe 114, which is fixedly connected to the center position of the filter disc 113. The air outlet of the second air pipe 114 is connected to multiple diversion pipes 115. The outside of the diversion pipe 115 is connected to multiple micro-electric control valves 116. The air outlet of the micro-electric control valve 116 passes through the inner wall of the filter disc 113 and is connected to a high-elasticity and wear-resistant capsule 118. One side of the inner wall of the high-elasticity and wear-resistant capsule 118 is fixedly connected to the inner wall of the movable groove 117. The side of the high-elasticity and wear-resistant capsule 118 away from the micro-electric control valve 116 is fixedly connected to the partition plate 119. The end of the diversion channel 200 away from the high-elasticity expansion capsule 201 is connected to the high-elasticity and wear-resistant capsule 118. The end of the second air pipe 114 away from the filter disc 113 is connected to a pushing structure.

[0046] When it is necessary to divide the interior of the detection barrel 101, the gas inside the second gas pipe 114 can be continuously transported to the interior of multiple diversion tubes 115. When the gas continues to enter the interior of multiple diversion tubes 115, the gas can be transported to the interior of the high-elasticity and wear-resistant capsule 118 by opening multiple micro-electric control valves 116. When the gas is transported to the interior of the high-elasticity and wear-resistant capsule 118, the high-elasticity and wear-resistant capsule 118 will expand. When the high-elasticity and wear-resistant capsule 118 expands, the partition plate 119 can be pushed to slide in the movable groove 117. When the partition plate 119 slides, when the partition plate 119 moves to the interior of the square filter hole, the inside of the filter hole can be sealed.

[0047] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: Compared with the existing technology, in this embodiment, during the detection process, the high-elastic and wear-resistant sac 118 can be used to push the partition plate 119 to close the square filter hole, thereby forming the internal space of the detection barrel 101 into two sections, and vertical fluidity detection is performed on the upper side, and the upper pressure is detected in real time by the first pressure sensor 110 during the vertical fluidity detection process, while the water-coal slurry can be sucked by the suction pump 602 in cooperation with the annular tube 601 at the lower side, and the lateral fluidity detection is achieved by sucking the water-coal slurry, and the suction force is detected by the second pressure sensor 600 during the suction process. The filter disc 113 and the partition plate 119 can not only realize the filtration of the water-coal slurry, but also can separate the pressure output by the air pump 108 and the suction generated by the suction pump 602 during the lateral fluidity and vertical fluidity detection processes, thereby reducing the mutual influence phenomenon and further enhancing the accuracy of the detection process.

[0048] Embodiment 2: Considering the poor fluidity of the water-coal slurry, when filtering using the carrier cover 103, some of the water-coal slurry will remain inside the square filter holes, causing blockage. In addition, strip-shaped impurities will also remain inside the water-coal slurry. Once the strip-shaped impurities enter the filter holes, it is very easy to cause blockage inside the filter holes. In response to the above technical problems, the present application proposes the following technical solutions to solve the above technical problems:

[0049] like Figure 5-10 As shown, the side of the dividing cutting plate 119 away from the diversion and conveying structure is in the shape of a blade and is sharpened.

[0050] Specifically, when gas enters the highly elastic and wear-resistant capsule 118 and expands, pushing the partition cutting plate 119, the partition cutting plate 119 will gradually move toward the inside of the square filter hole. When the partition cutting plate 119 moves toward the inside of the square filter hole, the impurities stuck in the square filter hole can be cut off by the blade end with a sharp edge at the front. When the impurities are cut off, the blockage caused inside the filter can be reduced. When the water-coal slurry accumulates inside the square filter hole, the water-coal slurry stuck in the square filter hole can also be cut off by the movement of the partition cutting plate 119. When the partition cutting plate 119 moves toward the inside of the square filter hole, the water-coal slurry accumulated inside the square filter hole can also be squeezed. By squeezing the water-coal slurry, the position of the accumulated water-coal slurry is changed, and the adhesion between the water-coal slurry and the square filter hole is promoted, so that the water-coal slurry and the square filter hole are separated, thereby reducing the blockage of the square filter hole.

[0051] like Figure 6-Figure 7 As shown, a plurality of electromagnetic suction plates 400 are fixedly connected to the interior of the filter disc 113, and the plurality of electromagnetic suction plates 400 are used to attract the partition cutting plate 119 to be closer to the inner wall of the square filter hole, and attract the partition cutting plate 119 to shear the impurities located on the inner wall of the square filter hole.

[0052] Specifically, when the electromagnetic suction plate 400 is started, the partition cutting plate 119 can be attracted. By attracting the partition cutting plate 119, the partition cutting plate 119's cutting force on impurities inside the square filter holes is strengthened, thereby strengthening the partition cutting plate 119's cutting effect on impurities inside the square filter holes.

[0053] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment one, in this embodiment, when the partitioning cutting plate 119 divides the square filter holes in the filter disc 113, the impurities blocked inside the square filter holes can also be cut by the sharpened cutting end, and when the impurities are cut, the situation of impurities blocking the square filter holes can be reduced.

[0054] Embodiment 3: Considering that after the partition plate 119 divides the interior of the square filter hole, the impurities located below the partition plate 119 may fall due to gravity, while the impurities located above the partition plate 119 may be squeezed and still adhere to the interior of the square filter hole, in order to solve the above technical problems, the present application proposes the following technical solutions, specifically:

[0055] like Figure 6 and Figure 7As shown, a diversion channel 200 is opened inside the partition cutting plate 119, and a high-elastic expansion bag 201 is integrally formed on the outside of the partition cutting plate 119. The outlet end of the diversion channel 200 is connected to the high-elastic expansion bag 201, and the inlet end of the diversion channel 200 is connected to the diversion conveying structure.

[0056] Specifically, during use, when the dividing cutting plate 119 is cutting and cleaning the inside of the square filter hole, gas can be continuously injected into the inside of the high-elastic wear-resistant capsule 118, so that the gas inside the high-elastic wear-resistant capsule 118 is continuously injected into the inside of the diversion channel 200. When the gas is continuously injected into the inside of the diversion channel 200, the high-elastic expansion capsule 201 can be expanded. When the high-elastic expansion capsule 201 is expanded, the impurities located inside the square filter hole will be pushed a second time, thereby pushing the impurities accumulated inside the square filter hole to the outside.

[0057] Furthermore, a plurality of inclined spray holes 300 are provided on the outside of the high-elastic expansion bladder 201. When the high-elastic expansion bladder 201 expands, the impurities inside the square filter holes are pushed to fall out. When the high-elastic expansion bladder 201 expands to a certain extent, the inclined spray holes 300 on the outside of the high-elastic expansion bladder 201 can be opened, thereby ejecting gas through the inclined spray holes 300. When the high-elastic expansion bladder 201 expands to a specified extent and ejects gas through the inclined spray holes 300, the water-coal slurry retained on the surface of the filter disc 113 can also be blown off, thereby reducing the accumulation of water-coal slurry on the surface of the filter disc 113.

[0058] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: Compared to the second embodiment, in this embodiment, a diversion channel 200 is provided within the partitioning plate 119, and a highly elastic expansion bladder 201 is integrally formed on its exterior. The two are connected via an internal airway and form a complete airflow path with the diversion and conveying structure. In actual operation, high-pressure gas is continuously injected into the highly elastic and wear-resistant bladder 118, driving the airflow through the diversion channel 200 into the highly elastic expansion bladder 201, causing it to expand directionally to form a flexible thrust, effectively stripping and expelling stubborn impurities from the filter pores. Simultaneously, multiple inclined injection holes 300 pre-installed on the surface of the highly elastic expansion bladder 201 automatically open during the expansion process, forming a directional airflow jet, which not only enhances the impurity removal effect but also simultaneously purges residual water-coal slurry from the surface of the filter disc 113, preventing media accumulation from affecting subsequent processes, thereby achieving synergistic optimization of filter pore cleaning and surface anti-clogging.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
