Description

Technical Field

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

[0002] As a clean coal-based fuel, water coal slurry is made by mixing coal (60%-70%) with water (30%-40%) and a small amount of additives, and has the characteristics of high combustion efficiency and low pollutant emissions. It is widely used in industrial boilers, power stations and chemical industries. 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 off-line laboratory analysis) have problems such as lag, large errors, and low efficiency.

[0003] In the patent with the patent name of water coal slurry fluidity detector and the publication number of CN119043990B, it is proposed that in the prior art, through the design of a U-shaped detection tube, a laser pen, a photosensitive receiver and an 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 through this value. However, the flow rate of the water coal slurry is different under different pressures, and the water coal slurry contains impurities such as solid particles and iron filings. These impurities are likely to cause inaccurate detection. Moreover, the water coal slurry is pumped by two impellers with constant rotational speeds to ensure that the pressure is fixed during pumping and conveying, and it filters the solid particles in the water coal slurry through a filtering method to reduce inaccuracies during the detection process. However, during the fluidity detection process, the position of the filter disc is fixed, and a large amount of impurities will be carried when passing through the water coal slurry, and the shapes and materials of the impurities are also different. Some strip-shaped impurities are easily stuck inside the filter disc, and when the strip-shaped impurities are stuck inside the filter screen, it is extremely easy to cause the filter disc to become blocked. When the filter disc is blocked, it is easy to cause a change in the suction pressure. Even when the two impellers rotate at a constant speed, the suction pressure is likely to be different. Therefore, a water coal slurry fluidity detector is proposed. Summary of the Invention

Specific embodiments

[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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1. As Figure 1 shown, the water coal slurry fluidity detector of the present application includes: Detection barrel 101, a upper flange cover plate 102 is fixedly connected to the detection barrel 101, a feeding structure is connected to the upper flange cover plate 102, a partition plate 111 is fixedly connected inside the detection barrel 101, a pressure inlet and detection cavity is formed between the partition plate 111 and the upper flange cover plate 102, a plurality of circulation channels 112 communicate below the partition plate 111, and flow meters are installed inside each of the plurality of circulation channels 112; Filter disc 113, the filter disc 113 is fixedly connected inside the detection barrel 101, a plurality of square filter holes are formed outside the filter disc 113, the filter disc 113 is communicated with the feeding structure, an adjusting structure is connected inside the filter disc 113, the adjusting structure is communicated with the square filter holes of the filter disc 113, and the adjusting structure is used to control the opening and closing of the square filter holes of the filter disc 113.

[0020] Specifically, during the use process, when the water coal slurry enters the pressure inlet and detection cavity, the water coal slurry is continuously conveyed into the plurality of circulation channels 112 by the external conveying pressure, and the flow meters inside the plurality of circulation channels 112 are used to monitor the fluidity of the water coal slurry. After the water coal slurry is discharged from the circulation channels 112, 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 towards 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 outside the filter disc 113 can filter the water coal slurry and reduce the presence of impurities.

[0021] As Figures 1 - 5 shown, a secondary suction chamber is formed between the lower part of the filter disc 113 and the inner bottom wall of the detection barrel 101. The bottom of the detection barrel 101 is communicated with an annular pipe 601. A plurality of flow meters are installed inside the annular pipe 601. One end of the annular pipe 601 far from the detection barrel 101 is communicated with a material suction pump 602.

[0022] Specifically, after the water coal slurry passes through the filter disc 113, it will enter the secondary suction chamber. When the water coal slurry enters the secondary suction chamber, the material suction pump 602 will suck the water coal slurry into the annular pipe 601, and the plurality of flow meters inside the annular pipe 601 are used to measure the fluidity of the water coal slurry after filtration.

[0023] As Figures 1 - 4 shown, an installation box 100 is installed outside the detection barrel 101. 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 pressure inlet and detection cavity, and the second pressure sensor 600 is located inside the secondary suction chamber. An outer heat conducting cover 500 is connected to the outside of the filter disc 113, and a plurality of heating rods 501 are connected to the inner wall of the outer heat conducting cover 500.

[0024] As shown Figures 1 - 9 in the figure, the pusher structure includes an upper flange cover plate 102, which is fixedly connected to the detection barrel 101 through a flange. A bearing cover 103 is communicated with the upper flange cover plate 102. A feed valve 104 and an air inlet valve 105 are respectively connected to the bearing cover 103. A material conveying pipe 106 is communicated with the inlet of the feed valve 104. A first air conveying pipe 107 is communicated with the inlet of the air inlet valve 105. One end of the first air conveying pipe 107 far from the air inlet valve 105 is communicated with an air pump 108. One end of the feed valve 104 far from the material conveying pipe 106 penetrates through the outer wall of the upper flange cover plate 102 and is communicated with a micro electric control valve 116. The outlet end of the micro electric control valve 116 is located inside the inlet pressure detection cavity. One end of the second air conveying pipe 114 far from the filter disc 113 penetrates through the outer walls of the upper flange cover plate 102 and the bearing cover 103 and is communicated with the air inlet valve 105. A shunt pipe 115 is communicated with the outer wall of the feed valve 104. The shunt pipe 115 penetrates through the outer wall of the upper flange cover plate 102 and is communicated with the inlet pressure detection cavity Specifically, during the use process, 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 material conveying pipe 106 and then injected into the interior of the micro electric control valve 116 through the feed valve 104. The micro electric control valve 116 will then convey the water coal slurry into the inlet pressure detection cavity. When the water coal slurry enters the inlet pressure detection cavity, the air pump 108 is started to inject gas into the second air conveying pipe 114 and the shunt pipe 115. When the gas is injected into the shunt pipe 115, the shunt pipe 115 will convey the gas into the inlet pressure detection cavity. When the gas enters the interior of the inlet pressure detection cavity, it will increase the pressure inside the inlet pressure detection cavity, thereby accelerating the situation of pushing the water coal slurry into the lower circulation channel 112. And when pushing, the internal pressure of the inlet pressure detection cavity 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 generated by the suction pump 602 inside the secondary suction chamber is detected by the second pressure sensor 600, realizing dynamic adjustment as a whole

[0025] Further, after the water coal slurry enters the secondary suction chamber, the adjustment structure is used to push the central control unit 109 to move and push the central control unit 109 into the square filter hole. After the central control unit 109 completely enters the square filter hole, the square filter hole can be blocked. After blocking the square filter hole, the pressure transmitted from above will be truncated by the filter disc 113. In the case of truncation, the pressure transmitted from the air pump 108 above will not affect the detection of the second pressure sensor 600 below

[0026] Furthermore, after the internal space of the detection barrel 101 is separated by the filter disc 113 and the partition cutting plate 119, the vertical fluidity of the detected water coal slurry can be realized through the circulation channel 112 above, while the horizontal fluidity detection can be realized through the annular pipe 601 below.

[0027] As Figure 3 and Figure 8 shown, the second pressure sensor 600 is located inside the secondary suction chamber. An outer thermal conduction cover 500 is connected to the outside of the filter disc 113, and a plurality of heating rods 501 are connected to the inner wall of the outer thermal conduction cover 500.

[0028] Specifically, during the detection of the fluidity of the water coal slurry, heat can also be generated by starting the heating rod 501. In the case where heat is generated by the heating rod 501, the heat will be transmitted to the water coal slurry through the outer thermal conduction cover 500, thereby avoiding the situation where the fluidity becomes poor due to the cooling of the water coal slurry. And the heating rod 501 contacts the filter disc 113 below, so that the material accumulated on the filter disc 113.

[0029] As Figures 1 - 7 shown, the adjusting structure includes a plurality of moving grooves 117. The plurality of moving grooves 117 communicate with the square filter holes. A partition cutting plate 119 is slidably connected inside the moving grooves 117. A diversion and conveying structure is connected to the side of the partition cutting plate 119 away from the square filter holes.

[0030] The diversion and conveying structure includes a second air pipe 114. The second air pipe 114 is fixedly connected to the central position of the filter disc 113. The air outlet of the second air pipe 114 communicates with a plurality of diversion pipes 115. A plurality of micro electric control valves 116 are connected to the outside of the diversion pipes 115. The air outlet of the micro electric control valve 116 penetrates through the inner wall of the filter disc 113 and communicates with a highly elastic and wear-resistant capsule 118. One side of the inner wall of the highly elastic and wear-resistant capsule 118 is fixedly connected to the inner side wall of the moving groove 117. The side of the highly elastic and wear-resistant capsule 118 away from the micro electric control valve 116 is fixedly connected to the partition cutting plate 119. One end of the diversion hole 200 away from the highly elastic expansion capsule 201 is connected to the highly elastic and wear-resistant capsule 118. The end of the second air pipe 114 away from the filter disc 113 communicates with a pushing structure.

[0031] When it is necessary to divide the inside of the detection barrel 101, the gas inside the second gas delivery pipe 114 can be continuously delivered into the inside of a plurality of shunt pipes 115. When the gas continuously enters the inside of the plurality of shunt pipes 115, the gas can be respectively delivered into the inside of the highly elastic wear-resistant capsules 118 by opening a plurality of micro electric control valves 116. When the gas is delivered into the inside of the highly elastic wear-resistant capsules 118, the highly elastic wear-resistant capsules 118 will expand. When the highly elastic wear-resistant capsules 118 expand, the partition cutting plate 119 can be pushed to slide inside the moving groove 117. When the partition cutting plate 119 slides, when the partition cutting plate 119 moves into the square filter holes, the inside of the filter holes can be blocked.

[0032] The technical solution in the above embodiment of the present application has at least the following technical effects or advantages: Compared with the prior art, in this embodiment, during the detection process, the partition cutting plate 119 can be pushed by the highly elastic wear-resistant capsule 118 to close the square filter holes, so as to divide the internal space of the detection barrel 101 into two sections. The vertical fluidity detection is carried out above, and during the vertical fluidity detection, the upper pressure is detected in real time by the first pressure sensor 110. Below, the water coal slurry can be sucked by the suction pump 602 cooperating with the annular pipe 601 to realize the horizontal fluidity detection. During the suction process, the suction force is detected by the second pressure sensor 600. The filter disc 113 cooperating with the partition cutting plate 119 can not only filter the water coal slurry, but also separate the pressure output by the air pump 108 and the suction force generated by the suction pump 602 during the horizontal and vertical fluidity detection processes, reducing the phenomenon of mutual influence and further enhancing the accuracy during the detection process.

[0033] Embodiment 2: Considering that the fluidity of the water coal slurry is poor, when using the bearing cover 103 for filtration, part of the water coal slurry will remain inside the square filter holes, causing blockage. And there is also the phenomenon that strip impurities remain in the water coal slurry. Once the strip impurities enter the filter holes, it is extremely easy to cause blockage inside the filter holes. In view of the above technical problems, the present application proposes the following technical solution to solve the above technical problems: As Figures 5 - 10 shown, the shape of the partition cutting plate 119 on the side away from the shunt delivery structure is blade-shaped and is edge-treated.

[0034] Specifically, when gas enters the high-elastic and wear-resistant bladder 118 and expands to push the partition cutting plate 119, the partition cutting plate 119 will gradually move into the square filter hole. When the partition cutting plate 119 moves into the square filter hole, the impurities clamped in the square filter hole can be cut off by the blade end with a front edge. When cutting off the impurities, the blockage phenomenon inside the filter screen can be reduced. And when the water-coal slurry accumulates in the square filter hole, the water-coal slurry clamped 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 into the square filter hole, the water-coal slurry accumulated in the square filter hole can also be extruded. By extruding the water-coal slurry, the position of the accumulated water-coal slurry is changed, the adhesion between the water-coal slurry and the square filter hole is promoted, so that the water-coal slurry is separated from the square filter hole, reducing the blockage of the square filter hole.

[0035] As Figures 6 - 7 shown, a plurality of electromagnetic suction plates 400 are fixedly connected inside the filter disc 113. The plurality of electromagnetic suction plates 400 are used to attract the partition cutting plate 119 to further approach 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.

[0036] 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 cutting force of the partition cutting plate 119 on the impurities inside the square filter hole is strengthened, and the cutting effect of the partition cutting plate 119 on the impurities inside the square filter hole is strengthened.

[0037] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, when the partition cutting plate 119 divides the square filter hole in the filter disc 113, the impurities blocked inside the square filter hole can also be cut by the cutting edge of the cutting knife. When cutting the impurities, the situation of impurities blocking inside the square filter hole can be reduced.

[0038] Embodiment 3: Considering that after the partition cutting plate 119 cuts inside the square filter hole, the impurities located below the partition cutting plate 119 may fall due to gravity, and the impurities located above the partition cutting plate 119 may still adhere to the inside of the square filter hole under the condition of being squeezed. For the above technical problems, the present application proposes the following technical solutions to solve the above technical problems. Specifically: As Figure 6 and Figure 7As shown in the figure, a flow diversion channel 200 is provided inside the partition cutting plate 119, and a highly elastic expansion bladder 201 is integrally formed outside the partition cutting plate 119. The outlet end of the flow diversion channel 200 is connected to the highly elastic expansion bladder 201, and the inlet end of the flow diversion channel 200 is connected to the flow diversion and conveying structure.

[0039] Specifically, during the use process, when the partition cutting plate 119 cuts and cleans the inside of the square filter holes, gas can also be continuously injected into the highly elastic wear-resistant bladder 118, so that the gas inside the highly elastic wear-resistant bladder 118 is continuously injected into the flow diversion channel 200. When the gas is continuously injected into the flow diversion channel 200, the highly elastic expansion bladder 201 can be inflated. When the highly elastic expansion bladder 201 is inflated, the impurities located inside the square filter holes will be pushed a second time, so as to push the impurities accumulated inside the square filter holes to the outside.

[0040] Furthermore, a plurality of inclined spray holes 300 are provided outside the highly elastic expansion bladder 201. When the highly elastic expansion bladder 201 expands to push the impurities located inside the square filter holes to fall, and when the highly elastic expansion bladder 201 expands to a certain extent, the inclined spray holes 300 outside the highly elastic expansion bladder 201 can be opened, so as to spray gas through the inclined spray holes 300. When the highly elastic expansion bladder 201 expands to a specified degree and sprays through the inclined spray holes 300, the water-coal slurry remaining on the surface of the filter disc 113 can also be blown off, reducing the situation of water-coal slurry accumulating on the surface of the filter disc 113.

[0041] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, a diversion channel flow diversion channel 200 is provided inside the partition cutting plate 119, and an elastic expansion chamber highly elastic expansion bladder 201 is integrally formed outside it. The two are connected through an internal air duct and form a complete air flow path with the flow diversion and conveying structure. During actual operation, by continuously injecting high-pressure gas into the highly elastic wear-resistant bladder 118, the air flow is driven to enter the highly elastic expansion bladder 201 through the flow diversion channel 200, so that it expands directionally to form a flexible thrust, effectively peeling off and discharging the stubborn impurities in the filter holes; at the same time, a plurality of injection holes inclined spray holes 300 preset on the surface of the highly elastic expansion bladder 201 are automatically opened during the expansion process, forming a directional air flow jet, which not only enhances the impurity removal effect, but also can synchronously blow the water-coal slurry remaining on the surface of the filter disc 113, avoiding the accumulation of media from affecting the subsequent process, so as to realize the coordinated optimization of filter hole cleaning and surface anti-blocking.

[0042] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
