[0002] Since the raw material of the gasification coal supply system is coal, the main way is to transport it by conveyor belt. Because the dust is heavy during the coal transportation, the dust is heavy during the feeding and conveyor belt transportation, which affects the environment and physical and mental health.

[0003] Before the existing conveying device conveys coal materials, it is necessary to put the coal materials through a feeding facility. When putting them, due to the falling collision of the coal materials, more dust will be generated from the raw coal.

[0004] Although there are currently dust removal facilities for coal materials, such as atomization removal, traditional atomization is prone to high water consumption and the atomized water particles are large, resulting in an increase in the wetting degree of the coal materials. And during the conveying of the coal materials, some raw materials containing humidity will adhere to the conveyor belt, resulting in an impact on the conveying capacity of the conveyor belt and requiring frequent cleaning by personnel.

[0005] Therefore, this application proposes a raw coal conveying device with a dust removal system. Content of the Utility Model

[0027] Embodiment 1

[0028] To solve the technical problems in the background art, the following raw coal conveying device with a dust removal system is provided:

[0029] Combined with Figures 1-5 As shown, the raw coal conveying device with a dust removal system provided by the present utility model includes a conveyor trough body 1. One side of the top of the conveyor trough body 1 is fixedly installed with a feeding cavity 3. The two sides of the feeding cavity 3 are respectively provided with a material guiding port 31 and a discharging port 32. The top of the feeding cavity 3 is assembled with a dust reduction component 2 extending into the interior. The bottom of the conveyor trough body 1 is fixedly installed with a support frame 9. The support frame 9 and one side of the feeding cavity 3 are jointly assembled with a loading component 4, and the loading component 4 corresponds to the material guiding port 31. A conveying component 8 is assembled inside the conveyor trough body 1. A scraping component 6 is butt-joint installed in the conveyor trough body 1 on one side of the conveying component 8. A material blocking component 7 is fixedly installed on the feeding cavity 3 at the position of the discharging port 32;

[0030] During this period, the raw materials are conveyed through the conveying component 8 in the conveying trough 1, and the pre-loading of the raw materials is realized by the feeding component 4, so that the feeding height can be adjusted in real time, the loading range of the loading facilities can be reduced, and the feeding of the device can be made more efficient. The dust reduction component 2 can perform micron dry fog dust reduction operation on the dust generated by the incoming raw coal, which is more energy-saving than traditional atomization, and the coal material will not be affected by wetting, ensuring that the raw coal will not generate dust when exported. Moreover, the dust suppression points are set at the inlet and outlet, which can effectively prevent dust from overflowing from the two sides of the material port and increase the dust removal effect. Through the cooperation of the scraping component 6 and the conveying component 8, the device can not only convey the raw coal, but also scrape the adhering coal layer on the conveyor belt, preventing the coal material from sticking to the conveyor belt, ensuring the conveying capacity of the device and avoiding frequent cleaning by personnel. The baffle component 7 can restrain the exported raw coal, ensuring that the conveyed raw coal can be gathered in the middle of the conveyor belt and preventing the raw coal from spilling out from both sides of the conveyor belt during conveying.

[0031] The dust reduction component 2 includes a water guide cavity 21, dust suppression nozzles 22, and a docking head 23. The docking head 23 extending into the interior is fixedly installed at the top of the feeding cavity 3. The water guide cavity 21 is docked and installed at the bottom of the docking head 23. Dust suppression nozzles 22 are fixedly installed on both sides of the bottom of the water guide cavity 21; The feeding component 4 includes a feeding cylinder 41, a hydraulic cylinder 45, a hinged sliding part 46, and a movable seat 47. The movable seat 47 and the hydraulic cylinder 45 are respectively installed on the same side of the feeding cavity 3 and the support frame 9. The movable seat 47 and the hydraulic cylinder 45 are jointly installed with the feeding cylinder 41, and the connection between the feeding cylinder 41 and the hydraulic cylinder 45 is installed and connected through the hinged sliding part 46; The scraping component 6 includes a rotating shaft 61, a rubber scraping part 62, and a scraping plate 63. The rotating shaft 61 is docked and installed in the conveying trough 1 on one side of the conveying component 8. The scraping plate 63 is sleeved on the rotating shaft 61, and the rubber scraping part 62 is fixedly installed on the end face of the scraping plate 63;

[0032] During conveying, first drive the hydraulic cylinder 45, and support and adjust the feeding cylinder 41 through the telescopic movement of the hydraulic cylinder 45 to ensure that the feeding end of the feeding cylinder 41 meets the actual loading end of the raw coal. It should be noted that a spiral feeding rod for guiding is assembled inside the feeding cylinder 41. By driving the spiral feeding rod, the feeding cylinder 41 is promoted to complete the feeding operation of the raw coal. Water is introduced into the water guide cavity 21, and then atomization operation is carried out through the dust suppression nozzles 22, and an atomization effect is generated in the feeding cavity 3 to perform atomization dust reduction on the incoming raw coal. When the conveying component 8 conveys, it will synchronously drive the rotating shaft 61 to rotate, prompting the scraping plate 63 on the rotating shaft 61 to rotate accordingly. At that time, the scraping plate 63 will complete the scraping and cleaning of the conveyor belt through the rubber scraping part 62.

[0033] Embodiment 2

[0034] AsFigure 1 and Figure 5 As shown, on the basis of the above embodiments, the present embodiment further provides the following content:

[0035] In the present embodiment, the dust-removing assembly 2 further includes a conveying pipe 24, a dry fog main machine 25, a water-gas distribution box 26, and a water injection port 27.

The output end of the water-gas distribution box 26 is butt-connected with the conveying pipe 24, and the conveying pipe 24 extends out of the dry fog main machine 25 and is installed and connected with the docking head 23.

[0036] The dry fog main machine 25 is filled with water through the water injection port 27. During operation, the water-gas distribution box 26 is started, and the water is lifted into the water guiding cavity 21 through the conveying pipe 24, and then atomized for dust removal through the dust suppression nozzles 22.

[0037] In the present embodiment, the feeding assembly 4 further includes a blanking port 42, a first motor 43, and a feeding port 44. The first motor 43 is fixedly installed at the top of the feeding cylinder 41. The feeding port 44 is fixedly installed at the bottom outside the feeding cylinder 41. The blanking port 42 is fixedly installed at the top inside the feeding cylinder 41.

[0039] A material guiding platform 5 is fixedly installed on one side inside the blanking cavity 3, and the material guiding platform 5 is inclined and is located below the material guiding port 31.

[0040] By combining the above content, when the raw coal is output through the blanking port 42, the raw coal will first fall onto the material guiding platform 5, and the inclined shape of the material guiding platform 5 is used to complete the guiding of the coal material, so that the coal material is guided onto the conveying assembly 8 for conveying operation.

The material blocking plate 71 is butt-connected to the mounting seat 73 through the hinge shaft 72, and the discharge port 32 is located between the material blocking plates 71.

[0044] During this period, when the coal material is conveyed through the conveying component 8, the coal material will first be exported externally through the discharge port 32. And during the export process, the raw coal will be constrained by the baffle plate 71. With the cooperation of the hinge shaft 72, the baffle plate 71 can gather the coal material while conveying it, preventing leakage.

[0045] In this embodiment, the conveying component 8 includes a conveyor belt 81, a guiding roller 82, a transmission roller 83, a pulley 84, and a second motor 85. Inside the conveying trough 1, a conveyor belt 81 is assembled through the transmission roller 83, and guiding rollers 82 are evenly distributed in the conveying trough 1 within the conveyor belt 81.

[0046] On the front of the conveying trough 1, a second motor 85 is fixedly installed. The output end of the second motor 85 is installed and connected to the shaft end of the transmission roller 83. The other shaft end of the transmission roller 83 is assembled and connected to the shaft end of the rotating shaft 61 through the pulley 84, and the transmission roller 83 drives the rotating shaft 61 through the pulley 84.

[0047] During this period, when the second motor 85 is started, the output end of the second motor 85 will drive the transmission roller 83 to rotate. With the cooperation of the guiding roller 82, the conduction movement of the conveyor belt 81 is completed, realizing the conveying operation of the coal material.

[0048] And during the conveying process, the transmission roller 83 drives the rotating shaft 61 through the pulley 84, prompting the rotating shaft 61 to rotate synchronously. In this way, when the conveyor belt 81 is conveying, the scraping plate 63 will complete the scraping operation on the conveyor belt through the rubber scraping part 62, cleaning the adhering coal material on the conveyor belt 81 and ensuring the conveying capacity of the conveyor belt.
