Description

Technical Field

[0001] The utility model relates to the field of coal anti-blocking detection, in particular to a cone-surface air-blowing coal transportation anti-blocking detection device. Background Art

[0002] Coal screening can usually be achieved through gravity screening to separate the coal that meets the requirements. During the screening process, the coal needs to be screened through holes of fixed sizes. During the screening process, the coal can easily get stuck in the holes, which affects the normal screening of the coal and easily causes the holes to be blocked. After the holes are blocked, they cannot be discovered in time, which affects the coal screening and reduces the screening efficiency. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] In one embodiment, please refer to the attached manual. Figure 1-4 As shown, the utility model describes a conical air blowing coal transportation anti-blockage detection device, including a conveying component, the conveying component is used to convey coal, the conveying component is provided with an air supply component, the air supply component is provided with a plurality of air outlet holes 2, the air outlet holes 2 blow air upward to detect the air pressure at the orifice; the air supply component is closed with one end larger than the other end, so that the air pressure blown out from the air outlet holes 2 is the same.

[0020] The conveying assembly includes a conveying plate 1 and a conveying pipe 6, and both the conveying plate 1 and the conveying pipe 6 are arc-shaped structures.

[0021] The provided conveying assembly can convey coal, which is convenient for coal screening. During the coal screening process, it can be discovered in time that coal is blocking the air outlet 2. The air supply assembly is used to discharge air from the air outlet 2 through the fan. When the air outlet 2 is blocked by coal, the pressure detection device above the air outlet 2 detects for a long time that the air discharged from the air outlet 2 does not reach the threshold, thereby sounding an alarm, thereby facilitating the discovery that the corresponding air outlet 2 is blocked, and the air outlet 2 is cleaned, so that the coal can pass through the air outlet 2 normally to continue to complete the coal screening.

[0022] In one embodiment, please refer to the attached manual. Figure 1-2 As shown, the air supply component includes a conical tube 3 arranged on the conveying plate 1, the interior of the conical tube 3 is provided with an inner cavity 4 for air flow, the conical tube 3 is connected with the air outlet 2, and a sealing plate 5 is provided at the tail end of the conical tube 3, and the sealing plate 5 is used to seal the conical tube 3.

[0023] The size of the air inlet end of the tapered tube 3 is smaller than that of the tail end.

[0024] When the air is sent into the air inlet by the fan, the gas will continue to increase inside the inner cavity 4. Due to the small size of the air inlet and the fast air flow rate, the size of the tail end of the tapered tube 3 is larger than that of the air inlet. In order to make the pressure inside the inner cavity 4 equal everywhere, the length and taper of the tapered tube 3 are designed to achieve the goal of making the blowing pressure of the air outlet 2 equal everywhere after the air is taken in. The pressure sensor can detect the blockage according to the pressure at the air outlet 2, thereby facilitating the cleaning of the blocked air outlet 2 to achieve the effect of relieving the blockage.

[0025] In another embodiment, please continue to refer to the attached manual. Figure 3-4 As shown, the air supply assembly further includes an air channel 7 disposed below the delivery pipe 6 , and the air channel 7 is communicated with the air outlet 2 opened on the delivery pipe 6 .

[0026] The delivery pipe 6 and the airway 7 are an integrally formed structure.

[0027] When it is necessary to transport coal over a long distance, the process requirements for the air supply components are high and the pipelines cannot be spliced. Therefore, it is necessary to set an integrally formed air duct 7 under the conveying pipe 6 to prevent air leakage during transportation, thereby ensuring that the pressure inside the air duct 7 is equal everywhere; the gas can be evenly discharged upward from the inside of the air outlet 2 through the air duct 7, and the pressure sensor detects the pressure of the discharged gas, thereby facilitating the judgment of the blockage situation.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model. The scope of protection required by the utility model is defined by the attached claims and their equivalents.
