Description

Technical Field

[0001] The utility model belongs to the technical field of concentration detection instruments, and specifically relates to a coal slurry non-horizontal pipeline concentration testing instrument. Background Art

[0002] Coal slurry is a slurry made by mixing pulverized coal and water, usually used for combustion or power generation. The concentration of coal slurry is usually detected by measuring the content of pulverized coal in the slurry. Coal slurry concentration detection is an important step that helps improve production efficiency and product quality.

[0003] However, when testing coal slurry, the detection device is generally connected to the pipeline for conveying the coal slurry to ensure real-time detection and reduce coal slurry leakage. However, since the pipeline for conveying the coal slurry is generally installed for a long time, the pipeline for conveying the coal slurry may be in an inclined state. When the inclined pipeline is connected to the device, the device will also be in an inclined state. The inclined detection device will be greatly disturbed by external factors during the detection process, resulting in large errors in the detection results, which in turn affects the quality of the product and production efficiency.

[0004] In order to solve the above problems, this application proposes a coal slurry non-horizontal pipeline concentration testing instrument. Utility Model Content

[0005] In view of the problems in the related art, the utility model proposes a coal slurry non-horizontal pipeline concentration testing instrument to overcome the above technical problems existing in the existing related art.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The top of the tube has a hole, and the bottom of the tube has a hole, and the bottom of the tube has a check valve in it, and the check valve is output.

[0008] Preferably, a fixing rod is fixedly connected to the interior of the connecting tube, a fixing seat is fixedly connected to the fixing rod, a rotating rod is rotatably connected to one side of the fixing seat, and a fan blade is fixedly connected to the outer wall of the rotating rod.

[0009] By setting a fixed rod, a fixed seat, a rotating rod and fan blades, the coal slurry inside the connecting pipe can be stirred and blocked. When the coal slurry flows to the fan blades through the connecting pipe, the fan blades rotate under the drive of the coal slurry, so that the coal slurry begins to mix. At the same time, the flow rate of the coal slurry is reduced, thereby reducing the interference of some factors on the concentration detector, and thus making the concentration detector more accurate when detecting the coal slurry.

[0010] Preferably, a sealing sleeve is fixedly connected to a surface of the fixing seat close to the rotating rod, and the interior of the sealing sleeve is in contact with the outer wall of the rotating rod.

[0011] By setting up a sealing sleeve, the connection between the rotating rod and the fixed seat is protected, preventing dust and impurities inside the coal slurry from directly contacting the connection between the fixed seat and the rotating rod, thereby avoiding affecting the rotation of the fan blades, and further avoiding affecting the stirring and deceleration effects of the fan blades.

[0012] Preferably, a protective sleeve is fixedly connected to the bottom of the concentration detector, and the protective sleeve extends to the inside of the connecting pipe through holes provided on the first connecting ring and the second connecting ring. The measuring rod of the concentration detector is located inside the protective sleeve.

[0013] By setting up a protective cover, the measuring rod of the concentration detector can be protected to avoid damage to the measuring rod of the concentration detector under the erosion of coal slurry, thereby avoiding the damage to the measuring rod of the concentration detector affecting the detection effect and further avoiding affecting the subsequent work.

[0014] Preferably, the top of the second connecting ring is fixedly connected to a support rod, and the top of the support rod is fixedly connected to the outer wall of the concentration detector.

[0015] By setting a support rod, the concentration detector can be fixed to prevent the concentration detector from escaping from the range of the second connecting ring during use, thereby preventing the concentration detector from being damaged and further preventing the damage to the concentration detector from affecting the detection of coal slurry.

[0016] Preferably, a sealing block is fixedly connected to the bottom of the second connecting ring, a sealing groove is provided on the top of the first connecting ring, and an outer wall of the sealing block fits in the sealing groove of the first connecting ring.

[0017] By providing a sealing groove and a sealing block, the connection between the first connecting ring and the second connecting ring is sealed, preventing the coal slurry inside the connecting pipe from flowing out through the connection, thereby avoiding waste of resources and further avoiding environmental pollution.

[0018] Preferably, a spring is fixedly connected to the outer wall of the connecting pipe, a clamping plate is fixedly connected to the spring, and the clamping plate is slidably connected to the connecting plate.

[0019] By setting springs and clamping plates, the connection plate can be positioned to prevent the connection plate from shaking when not in use, affecting the transportation of the device, thereby avoiding damage during transportation and further avoiding affecting the use of the device.

[0020] In summary, the technical effects and advantages of the utility model are:

[0021] The angle of the concentration detector is controlled by the connecting pipe, the first connecting ring, the second connecting ring, the concentration detector, the folding hose, the rotating ring, the first connecting block, the connecting plate, the second connecting block, the fixed ring, the first groove, the first fixed block, the second groove and the second fixed block, so that the concentration detector can always be in a relatively horizontal state. The fixed ring is fixed to the relatively inclined pipe by using the connecting plate, and the connecting plate and the fixed ring are fixed by the mutual cooperation of the first groove and the first fixed block, the second groove and the second fixed block, so that the connecting pipe and the concentration detector are in a relatively horizontal state, thereby preventing the inclination of the concentration detector from affecting the concentration detection result of the coal slurry.

[0022] Through the mutual cooperation of the fixed rod, the fixed seat, the rotating rod and the fan blades, the stirring and blocking of the coal slurry inside the connecting pipe are achieved. When the coal slurry flows to the fan blades through the connecting pipe, the fan blades rotate driven by the coal slurry, so that the coal slurry begins to mix. At the same time, the flow rate of the coal slurry is reduced, thereby reducing the interference of some factors on the concentration detector, thereby making the concentration detector more accurate when detecting the coal slurry.

[0037] Working principle:

[0038] When using the device, the staff connects the connecting pipe 1 to the pipe for conveying coal slurry by folding the hose 5, and then cooperates with the first connecting block 7, the connecting plate 8 and the second connecting block 9 to make the fixing ring 10 fit the pipe for conveying coal slurry, and fixes the fixing ring 10 to the pipe for conveying coal slurry by the nuts and bolts provided on the fixing ring 10. After the fixing ring 10 is connected, the staff begins to adjust the position of the connecting pipe 1. After the connecting pipe 1 is in a relatively horizontal state, the staff fixes the connecting plate 8 by the first groove 11 and the first fixing block 12, and fixes the fixing ring 10 by the second groove 13 and the second fixing block 14, so that the angle and position of the connecting pipe 1 are fixed. During the use of the device, when the coal slurry flows into the connecting pipe 1, it will impact the fan blades 18, causing the fan blades 18 to rotate. The rotation of the fan blades 18 is used to block and stir the coal slurry, so that the circulation inside the coal slurry connecting pipe 1 can be slower, thereby reducing the concentration detector 4 so that the coal slurry can be more accurate in detecting the coal slurry.
