Description

Technical Field

[0001] This utility model relates to the field of coal-water slurry technology, and in particular to a testing device for additives used in the production of coal-water slurry. Background Technology

[0002] Coal-water slurry is a new, efficient, and clean coal-based fuel. It is a liquid fuel composed of 70%–75% pulverized coal and 25%–30% water, with the addition of 0.2%–5% trace additives. It is a low-pollution, high-efficiency, pipeline-transportable alternative to oil-based coal-based fluid fuel. While obtaining the same amount of heat, coal-water slurry can save coal, increase calorific value, and reduce greenhouse gas emissions, while also being transportable and stored like oil.

[0003] A search revealed a water-coal slurry fluidity tester with application number 202222072749.X, comprising a base, columns, a U-shaped detection tube, a laser pointer, and a photosensitive receiver. Two sets of columns are provided, with two sets of connecting components, a first mounting beam, and a second mounting beam arranged sequentially from top to bottom between the two sets of columns. A glass funnel is detachably connected to one set of connecting components. The U-shaped detection tube is detachably connected to the column. Two sets of laser pointers and photosensitive receivers are provided respectively, and the laser pointers and photosensitive receivers are configured in conjunction. An electronic stopwatch is electrically connected between the two sets of photosensitive receivers.

[0004] However, while the aforementioned coal-water slurry flowability tester is useful for testing the flowability of coal-water slurry, it is inconvenient to stir the coal-water slurry additives evenly before testing, which will seriously affect the accuracy of the test results. Therefore, we propose a coal-water slurry additive testing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings mentioned above by providing a testing device for additives in the production of coal-water slurry.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A testing device for coal-water slurry additives includes a base, a gantry frame fixedly connected to the top of the base, a cylinder containing coal-water slurry additives fixedly connected to the top of the gantry frame, a cover fixedly connected to the top of the cylinder, a mixing mechanism between the cover and the cylinder, a U-shaped detection tube between the gantry frame and the base, a detection mechanism between the U-shaped detection tube and the gantry frame, a feed pipe fixedly connected to the top of the cylinder, a discharge pipe fixedly connected to the bottom of the cylinder, the bottom end of the discharge pipe being movably inserted into the left port of the U-shaped detection tube, and a solenoid valve installed on the discharge pipe.

[0008] As a preferred embodiment of this utility model, the detection mechanism includes two mounting plates fixedly connected to the inner wall of one side of the gantry frame, and a timer fixedly connected to one side of the gantry frame. A laser pen and a laser receiver are fixedly connected to the front side of the mounting plates, and the U-shaped detection tube is located between the laser pen and the laser receiver.

[0009] As a preferred embodiment of this utility model, a controller is fixedly connected to one side of the gantry frame, and the timer, laser pointer, and laser receiver are all electrically connected to the controller.

[0010] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to the inner walls of both sides of the gantry frame, and a fixing half-ring is fixedly connected to the side of the two fixing plates that are close to each other. A rotating half-ring is rotatably connected to the rear side of the fixing half-ring, and ear plates are fixedly connected to the front side of both the fixing half-ring and the rotating half-ring. The same bolt is threaded onto the two ear plates, and the U-shaped detection tube is movably sleeved between the fixing half-ring and the rotating half-ring.

[0011] As a preferred embodiment of this invention, a pad is fixedly connected to the front side of the mounting plate, and the laser pointer is fixedly connected to the front side of the pad.

[0012] In a preferred embodiment of this invention, the mixing mechanism includes a drive motor fixedly connected to the rear side of the cover, and a rack fixedly connected between the cover and the cylinder. A turntable is fixedly connected to the output shaft of the drive motor. A push-pull rod is rotatably connected to the front side of the turntable. A lifting plate is rotatably connected to the bottom end of the push-pull rod. A stirring shaft is rotatably connected to the bottom of the lifting plate. Several stirring rods are fixedly connected to the outer side of the stirring shaft. A horizontal shaft is rotatably connected to the bottom of the lifting plate. A lower bevel gear is fixedly sleeved on the outer side of the stirring shaft. An upper bevel gear and a gear are fixedly connected sequentially from left to right on the outer side of the horizontal shaft. The gear meshes with the rack, and the upper bevel gear meshes with the lower bevel gear.

[0013] In a preferred embodiment of this utility model, the top of the lifting plate has a rectangular opening, the rack is slidably fitted inside the rectangular opening, the cover and the cylinder are fixedly connected by the same guide rod, and the lifting plate is slidably fitted outside the guide rod.

[0014] As a preferred embodiment of this invention, a stabilizing plate is fixedly connected to the bottom of the lifting plate, and the horizontal shaft is rotatably connected to the stabilizing plate.

[0015] In this utility model, a testing device for producing coal-water slurry additives is described. A drive motor rotates a turntable, which in turn drives a push-pull rod and a lifting plate to reciprocate up and down. The lifting plate then drives a stirring shaft and a stirring rod to reciprocate up and down, thus stirring the coal-water slurry additives. Simultaneously, as the lifting plate moves up and down, it drives a gear to move up and down. Fixed to a rack, the gear rotates as it moves up and down, driving the horizontal shaft and upper bevel gear to rotate. The upper bevel gear then drives the lower bevel gear, the stirring shaft, and the stirring rod to rotate, thereby driving the stirring rod to rotate and reciprocate up and down simultaneously. This allows for movable stirring, resulting in a larger stirring area, better mixing, and thorough stirring of the coal-water slurry additives.

[0016] In this utility model, a coal-water slurry additive testing device is described. After mixing, the solenoid valve is opened, and the coal-water slurry additive flows from the feed pipe into the U-shaped testing tube. The coal-water slurry additive overflows from the bottom laser pointer to the top laser pointer. Utilizing the light-blocking properties of the coal-water slurry, the light column between the laser pointer and the photosensitive receiver is blocked. The time difference between the two sets of laser receivers stopping receiving the laser is displayed on the timer, and the test result is fed back through this value.

[0017] This utility model has a reasonable structural design. By rotating and reciprocating up and down the stirring rod, it can perform up and down reciprocating stirring in a movable manner, resulting in a larger stirring area and better mixing effect. It can fully stir the coal-water slurry additives and avoid the incomplete stirring that would affect the accuracy of the test. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A testing device for producing coal-water slurry additives includes a base 1, a gantry frame 2 fixedly connected to the top of the base 1, a cylinder 5 containing coal-water slurry additives fixedly connected to the top of the gantry frame 2, a cover 6 fixedly connected to the top of the cylinder 5, a mixing mechanism 7 provided between the cover 6 and the cylinder 5, a U-shaped detection tube 31 provided between the gantry frame 2 and the base 1, a detection mechanism 3 provided between the U-shaped detection tube 31 and the gantry frame 2, a feed pipe 8 fixedly connected to the top of the cylinder 5, a discharge pipe 9 fixedly connected to the bottom of the cylinder 5, the bottom end of the discharge pipe 9 being movably inserted into the left port of the U-shaped detection tube 31, and a solenoid valve 10 provided on the discharge pipe 9.

[0025] Furthermore, refer to Figure 1 and Figure 3 As shown, the detection mechanism 3 includes two mounting plates 33 fixedly connected to the inner wall of one side of the gantry 2, and a timer 32 fixedly connected to one side of the gantry 2. A laser pointer 35 and a laser receiver 36 are fixedly connected to the front side of the mounting plate 33. A U-shaped detection tube 31 is located between the laser pointer 35 and the laser receiver 36. A controller 4 is fixedly connected to one side of the gantry 2. The timer 32, the laser pointer 35 and the laser receiver 36 are all electrically connected to the controller 4.

[0026] Using the above scheme: After mixing, open the solenoid valve 10, and the coal-water slurry additive flows from the feed pipe 9 into the U-shaped detection tube 31. The coal-water slurry additive overflows from the bottom laser pointer 35 to the top laser pointer 35. Utilizing the light-blocking property of the coal-water slurry, it blocks the light column between the laser pointer and the photosensitive receiver. The time difference between the two sets of laser receivers 36 stopping receiving the laser is displayed on the timer, and the detection result is fed back through this value.

[0027] Furthermore, fixing plates 37 are fixedly connected to the inner walls of both sides of the gantry frame 2. Fixing half-rings 38 are fixedly connected to the side of the two fixing plates 37 that are close to each other. Rotating half-rings 39 are rotatably connected to the rear side of the fixing half-rings 38. Ear plates 34 are fixedly connected to the front side of the fixing half-rings 38 and the rotating half-rings 39. The same bolt 30 is threaded onto the two ear plates 34. The U-shaped detection tube 31 is movably sleeved between the fixing half-rings 38 and the rotating half-rings 39. The setting of the fixing half-rings 38, the rotating half-rings 39 and the bolt 30 facilitates the installation and disassembly of the U-shaped detection tube 31, improving the efficiency of use.

[0028] Furthermore, a pad is fixedly connected to the front side of the mounting plate 33, and the laser pointer 35 is fixedly connected to the front side of the pad, which facilitates the installation of the laser pointer 35.

[0029] Furthermore, refer to Figure 1 , Figure 2 and Figure 4 As shown, the mixing mechanism 7 includes a drive motor 701 fixedly connected to the rear side of the cover 6, and a rack 708 fixedly connected between the cover 6 and the cylinder 5. A turntable 702 is fixedly connected to the output shaft of the drive motor 701. A push-pull rod 705 is rotatably connected to the front side of the turntable 702. A lifting plate 704 is rotatably connected to the bottom end of the push-pull rod 705. A stirring shaft 706 is rotatably connected to the bottom of the lifting plate 704. Several stirring rods 707 are fixedly connected to the outer side of the stirring shaft 706. A horizontal shaft 709 is rotatably connected to the bottom of the lifting plate 704. A lower bevel gear 712 is fixedly sleeved on the outer side of the stirring shaft 706. An upper bevel gear 711 and a gear 713 are fixedly connected to the outer side of the horizontal shaft 709 from left to right. The gear 713 meshes with the rack 708, and the upper bevel gear 711 meshes with the lower bevel gear 712.

[0030] The above solution involves a drive motor 701 that rotates a turntable 702. The turntable 702 then drives the push-pull rod 705 and the lifting plate 704 to reciprocate up and down. The lifting plate 704, in turn, drives the stirring shaft 706 and the stirring rod 707 to reciprocate up and down, thus stirring the coal-water slurry additive. Simultaneously, the lifting plate 704's up-and-down movement causes the gear 713 to move up and down. Fixed to the rack 708, the gear 713 rotates as it moves up and down, driving the horizontal shaft 709 and the upper bevel gear 711 to rotate. The upper bevel gear 711 then drives the lower bevel gear 712, the stirring shaft 706, and the stirring rod 707 to rotate and reciprocate up and down, thus enabling movable stirring. This results in a larger stirring area, better mixing, and more thorough stirring of the coal-water slurry additive.

[0031] Furthermore, a rectangular opening is provided at the top of the lifting plate 704, and the rack 708 is slidably sleeved in the rectangular opening. The same guide rod 703 is fixedly connected between the cover 6 and the cylinder 5. The lifting plate 704 is slidably sleeved on the outside of the guide rod 703, which facilitates the guidance of the lifting plate 704 and makes its movement more stable and smooth.

[0032] Furthermore, a stabilizing plate 710 is fixedly connected to the bottom of the lifting plate 704, and the horizontal shaft 709 is rotatably connected to the stabilizing plate 710, which helps to support the horizontal shaft 709 and make its rotation more stable.

[0033] In this invention, during use, the drive motor 701 drives the turntable 702 to rotate. The turntable 702 drives the push-pull rod 705 and the lifting plate 704 to reciprocate up and down. The lifting plate 704 drives the stirring shaft 706 and the stirring rod 707 to reciprocate up and down, thus stirring the coal-water slurry additive. Simultaneously, the up-and-down movement of the lifting plate 704 drives the gear 713 to move up and down. Fixed to the rack 708, the gear 713 rotates as it moves up and down, driving the horizontal shaft 709 and the upper bevel gear 711 to rotate. The upper bevel gear 711 then drives the lower bevel gear 712 and the stirring shaft 706 to rotate. The rotation of the stirring rod 707 drives the stirring rod 707 to rotate and move up and down simultaneously, thus enabling movable stirring. This results in a larger stirring area and better mixing effect, allowing for thorough stirring of the coal-water slurry additive. After mixing, the solenoid valve 10 is opened, and the coal-water slurry additive flows from the feed pipe 9 into the U-shaped detection tube 31. The coal-water slurry additive overflows from the bottom laser pointer 35 to the top laser pointer 35. Utilizing the light-blocking properties of the coal-water slurry, the light column between the laser pointer and the photosensitive receiver is blocked. The time difference between the two sets of laser receivers 36 stopping receiving the laser is displayed on the timer, and the detection result is fed back through this value.
