Description

Technical Field

[0001] The present invention relates to the technical field of coal, and in particular to a coal mixing device with a heating function. Background Art

[0002] The moisture content of coal affects its calorific value, which is directly related to its quality. For coal with high moisture content, external heat sources (energy) are usually required to improve its quality (such as pyrolysis and drying) to reduce moisture content, improve its calorific value and combustion performance. However, heating and improving high-moisture coal requires high energy consumption, which is not only costly, but also requires mixing different types of coal before heating. This mixing process requires manual stirring, which is cumbersome. Therefore, it is necessary to improve the existing equipment for heating and improving high-moisture coal. Summary of the Invention

[0003] Therefore, based on the above background, the present invention provides a coal mixing device with a heating function.

[0004] The technical solution provided by the present invention is:

[0005] A coal mixing device with a heating function includes a mixer, wherein the mixer has an inlet connected to an outlet of a high-frequency heating device, wherein the high-frequency heating device delivers heated iron blocks into the mixer through the inlet of the mixer, and the heated iron blocks are heated by the mixer while mixing with coal blocks added thereto;

[0006] The material mixed in the mixer falls onto the material conveyor belt through the discharge port. Above the material conveyor belt is an iron block transport belt. Above the iron block transport belt is a belt type iron remover. The belt type iron remover includes a strong magnetic part and a non-magnetic part. The iron block transport belt transports the iron blocks separated by the belt type iron remover to the high-frequency heating device.

[0007] Furthermore, the length extension direction of the belt-type iron remover is consistent with the traveling direction of the material conveyor belt.

[0008] Furthermore, the mixer includes a shell with propeller blades arranged therein, and an air outlet pipe is provided on the shell.

[0009] Furthermore, the port of the outlet pipe away from the shell is connected to a collecting pipe with one end blindly sealed, and the collecting pipe is connected to the cooling tower.

[0010] Furthermore, the strong magnetic part is close to the mixer.

[0011] Furthermore, the high-frequency heating device includes a coil.

[0012] The above technical solution has the following beneficial effects:

[0013] The present invention mixes the iron blocks heated by the high-frequency heating device with the coal, thereby heating the coal evenly. In the heating process, different coals can be evenly mixed, which saves the operation of mixing the coal in advance. The iron blocks cooled after heat exchange can be separated from the heated and upgraded coal through the cooperation of a material conveyor belt, an iron block transport belt and a belt-type iron remover, and then transported to the high-frequency heater again for heating and reuse.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features being described. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of these features.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Example 1: According to Figure 1 The coal mixing device shown has a heating function and includes a mixer 1. The feed port of the mixer 1 is connected to the discharge port of a high-frequency heating device 6. The high-frequency heating device 6 delivers heated iron blocks 8 into the mixer through the inlet of the mixer 1. The heated iron blocks 8 are heated by the mixer while mixing with the coal blocks added thereto.

[0021] The mixed material in the mixer 1 falls through the discharge port onto the conveyor belt 2. Above the conveyor belt 2 is an iron block conveyor belt 3. A belt iron remover is located above the iron block conveyor belt 3. The belt iron remover includes a strong magnetic portion 4 and a non-magnetic portion 5. The iron block conveyor belt 3 conveys the iron blocks separated by the belt iron remover to the high-frequency heating device. In specific applications, the iron blocks are 2 cm in size. The accompanying drawings are enlarged to better illustrate the iron and coal blocks.

[0022] The length extension direction of the belt type iron remover is consistent with the traveling direction of the material conveyor belt 2 .

[0023] The mixer 1 comprises a housing 12 with a propeller blade 13 therein, and an air outlet pipe 9 is provided on the housing 12. The mixer is essentially a screw conveyor.

[0024] The port of the outlet pipe 9 away from the shell 12 is connected to a collecting pipe 11 with one end blindly sealed, and the collecting pipe 11 is connected to a cooling tower.

[0025] The strong magnetic part 2 is close to the mixer 1 .

[0026] The high-frequency heating device 6 includes a coil 7 .

[0027] In specific applications, the high-frequency heating device: under a safety voltage of 36V, the high-frequency heating device excites eddy currents in the conductor through a high-frequency electromagnetic field, uses the frequency advantage to compensate for low-voltage limitations, and combines efficient circuit design and electromagnetic optimization to heat the iron block to 800 degrees.

[0028] The high-frequency heating device mixes the heated iron and raw coal together in a mixer. After the mixture completes heat exchange in the mixer, it all falls onto a conveyor belt. A belt-type iron remover is located above the conveyor belt, and an iron block conveyor belt is located below the belt remover and above the conveyor belt. When the mixture passes through the strong magnetic section of the belt remover, the iron blocks are attracted to the belt remover. When the iron blocks pass through the non-magnetic section of the belt remover, they fall onto the iron block conveyor belt and enter the high-frequency heating device again.

[0029] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
