Technical Field

[0001] This invention belongs to the field of metering device technology, and particularly relates to a coal-water-slag metering device based on a crushing mechanism. Background Technology

[0002] When the coal slag-water mixture extracted from the coal mine passes through the metering device, there are still many problems, such as some coal slag being too large, making it inconvenient to measure during coal-water-slag metering, making it difficult to pass through, increasing the requirements for filter components, damaging filter components, and making it difficult to form coal slag cakes when the coal slag is too large.

[0003] Therefore, it is essential to install a crushing mechanism in the coal slag metering device to crush the coal slag into small particles. Summary of the Invention

[0006] The crushing mechanism includes a protective cover, with heat dissipation fins on the outer perimeter of the protective cover; an outlet pipe is fixedly connected to the central opening of the protective cover; a rotating core is fixedly sleeved on the outer perimeter of the outlet pipe, and both the outlet pipe and the rotating core are wrapped with roller sleeves, wherein the roller sleeves 65 are located inside the protective cover; a rolling roller is wound around the outer perimeter of the roller sleeves; one end of the outlet pipe is fixedly connected to the input pipe of the metering device body.

[0007] The beneficial effects of this invention are as follows: In this invention, the protective cover, heat sink, inlet and outlet pipes, rotating core, roller sleeve, and rolling roller are designed to crush coal slag in coal slurry into small particles, thereby enabling the metering device to operate normally.

[0012] The present invention will now be described in detail with reference to the accompanying drawings, namely Figure 1, Figure 2, and Figure 3. Figure 3 As shown, a coal-water-slag metering device based on a crushing mechanism includes a metering device body 1, an electric motor 2 installed on the metering device body 1, a flow regulating handwheel 3 also installed on the metering device body 1, and a detection tube 4 fixedly connected to the opening on one side of the output pipe of the metering device body 1, and a particle sensor 5 fixedly connected to the top of the detection tube 4.

[0013] One type of coal slag metering device based on a crushing mechanism also includes a crushing mechanism 6, which is fixedly connected to the input pipe of the metering device body 1. It can crush the coal slag in the coal slurry, thereby enabling the metering device to be used normally and facilitating the next step of coal slag cake making.

[0014] The crushing mechanism 6 includes a protective cover 61, with heat dissipation fins 62 arranged around the outer center of the protective cover 61. An outlet pipe 63 is fixedly connected to the central opening of the protective cover 61. A rotating core 64 is fixedly sleeved on the outer center of the outlet pipe 63, and both the outlet pipe 63 and the rotating core 64 are wrapped with roller sleeves 65, which are located inside the protective cover 61. A crushing roller ball 66 is wound around the outer center of the roller sleeve 65. One end of the outlet pipe 63 is fixedly connected to the input pipe of the metering device body 1. When the external control panel detects the size of the coal slag particles in the coal slurry in the output pipe of the metering device body 1 through the particle sensor 5, the control panel will automatically control the crushing motor 67 to start, so that the rotating core 64 crushes the coal slurry through the crushing roller ball 66. The excessively large coal slag in the coal slurry is crushed, thereby ensuring that the coal slurry in the input pipe of the metering device body 1 reaches the required value.

[0015] The protective cover 61 is made of stainless steel with a circular cross-section. The protective cover 61 can protect the rolling mill ball 66 and prevent the rolling mill ball 66 from being damaged by human factors.

[0016] The outlet pipe 63 is made of stainless steel and is used to transport coal slurry to the metering device body 1.

[0017] The roller sleeve 65 is cylindrical, and a groove is provided on the outer periphery of the cylinder. The groove is circular.

[0018] The rolling mill balls 66 are set to 10 to 100 in number, and are round in shape. They are set inside the ball sleeve 65 and can roll in the groove inside the ball sleeve 65. In order to avoid the problem of rapid wear, the ball sleeve 65 and the rolling mill balls 66 are made of high manganese steel alloy material.

[0019] The electric motor 2 and the particle sensor 5 are electrically connected to the external control panel.

[0020] The particle sensor 5 is preferably one of a laser particle size sensor and a dynamic light scattering sensor. The laser particle size sensor determines the particle size distribution by measuring the scattering of laser light by the particles, while the dynamic light scattering sensor analyzes the particle size based on the fluctuations in the intensity of scattered light caused by the Brownian motion of the particles.

[0021] The crushing motor 67 is electrically connected to the control panel.

[0022] When the coal slurry enters the crushing mechanism 6 through the inlet pipe 68, the external control panel detects that the coal slurry particles in the input pipe of the metering device body 1 are large via the particle sensor 5. The control panel then automatically starts the crushing motor 67, driving the rotating core 64 to rotate. The rotating core 64 in turn drives the roller sleeve 65 to rotate, and the crushing rollers 66 crush the large coal particles in the coal slurry. After the crushing rollers 66 have been working for a period of time, when the particle sensor 5 detects that the coal slurry particles in the input pipe of the metering device body 1 meet the metering requirements, the crushing motor 67 stops rotating. The coal slag in the coal slurry, after being crushed by multiple crushing rollers 66, meets the metering requirements when it reaches the outlet pipe 63 and enters the metering device through the input pipe of the metering device body 1 for measurement.

[0023] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
