[0020] Specifically, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of an anti-blocking unloading device for cement production provided in an embodiment of the present application. Figure 2 This is a schematic diagram of the local structure of the feeding hopper provided in the embodiment of the present application. Figure 3A schematic diagram of the cross-sectional structure of a stepped chute provided in an embodiment of the present application. An anti-clogging unloading device 1000 applied to cement production includes a stepped chute 100. The stepped chute 100 has a certain inclination as a whole, thereby delaying the impact force caused by the material in the falling process, and reducing the generation of dust to a certain extent. The stepped chute 100 includes a discharge chute 120 arranged in a stepped shape, the top of the discharge chute 120 is connected to a feed hopper 110, and a discharge plate 130 is arranged at the bottom of the discharge chute 120. After the material is added through the feed hopper 110, it will be transported through the discharge chute 120 and fall into the discharge plate 130, and finally slide from the discharge plate 130 to the belt conveyor 200. The unloading plate 130 can be a steel plate welded to the bottom of the unloading chute 120. A supporting steel frame can also be provided at the unloading plate 130 to improve the stability of the unloading plate 130. The material will preferentially fall on the unloading plate 130 during the falling process, thereby reducing the impact damage to the belt conveyor 200 caused by the material falling directly on the belt conveyor 200. The belt conveyor 200 is provided at the bottom of the unloading plate 130, and the belt conveyor 200 conveys the material to the next process. A sealed buffer air box 140 is fixed on the outer wall of the unloading chute 120. The buffer air box 140 is connected to a high-pressure air pump 141, and the high-pressure air pump 141 is used to introduce high-pressure air into the buffer air box 140. The buffer air box 140 is connected to a plurality of first air supply pipes 150 through a first-level electromagnetic air supply valve 151, and the first-level electromagnetic air supply valve 151 is used to control the high-pressure air in the buffer air box 140 to enter the first air supply pipe 150. The other end of the first air supply pipe 150 extends and is fixed along the axial direction of the material discharge chute 120, and the first air supply pipe 150 is used to supply air to each second air supply pipe 160. A plurality of second air supply pipes 160 are arranged on the material discharge chute 120 at intervals along the axial direction of the material discharge chute 120, and each first air supply pipe 150 is sequentially connected with a plurality of second air supply pipes 160 along the length direction of the first air supply pipe 150. The second air supply pipe 160 is connected to the first air supply pipe 150 through a secondary electromagnetic air supply valve 161, and the secondary electromagnetic air supply valve 161 is used to control the connection state of the second air supply pipe 160 and the first air supply pipe 150. A plurality of third air supply pipes 170 are arranged on the second air supply pipe 160. The other end of the third air supply pipe 170 is inclined downward and connected to the inner cavity of the discharge chute 120. The third air supply pipe 170 can pass high-pressure air into the inner cavity of the discharge chute 120 to purge the interior of the discharge chute 120, so as to clear blockage and blow off the clinker compacted on the side wall of the discharge chute 120.

[0021] In the embodiment of the present application, during the working process, the material is fed from the feed hopper 110 and then fed to the belt conveyor 200 through the discharge chute 120 to complete the transfer. When it is necessary to clear or clean the discharge chute 120, the first-level electromagnetic air supply valve 151 and the second-level electromagnetic air supply valve 161 are controlled to open in sequence, thereby introducing high-pressure air into the discharge chute 120 for cleaning.

[0022] As can be seen from the above, in the embodiment of the present application, a high-pressure air pump 141 is provided to supply air to the buffer air box 140, the high-pressure air flow direction is guided by providing a first air supply pipe 150, a second air supply pipe 160 and a third air supply pipe 170, and a first solenoid valve and a second solenoid valve are provided for control. Specifically, the first solenoid valve and the second solenoid valve can be automatically controlled by introducing a PLC control box. Thus, the PLC control box can be used to control the interval opening of multiple first solenoid valves. When one of the first solenoid valves is opened, the second solenoid valve on the first air supply pipe 150 is opened in sequence accordingly, so that the high-pressure air can enter the corresponding second air supply pipes 160 in a more concentrated manner, ensuring that the high-pressure air has sufficient impact force during the cleaning process of each point, thereby improving the clearing effect. The present application also reduces the impact force of the material on the belt conveyor 200 by providing a blanking plate 130, thereby extending the service life of the equipment.

[0023] In some embodiments, the material discharge chute 120 includes a plurality of vertically arranged first chute tubes 121 and a plurality of inclined second chute tubes 122, and the plurality of first chute tubes 121 and the plurality of second chute tubes 122 are arranged in sequence in an interlaced and connected manner. In the embodiment of the present application, through the above arrangement, both the first chute tube 121 and the second chute tube 122 have a downward inclination angle, thereby effectively slowing down the falling speed of the material in the material discharge chute 120, reducing the impact force, and the material is not easy to accumulate inside the material discharge chute 120.

[0024] In some embodiments, the second air supply pipe 160 is arranged on the first chute barrel 121 in an inclined state, and the second air supply pipe 160 is arranged on the second chute barrel 122 in a vertical state. In the embodiment of the present application, through the above arrangement, the second air supply pipe 160 can be more closely fitted to the first chute barrel 121 and the second chute barrel 122. At the same time, the inclined arrangement on the first chute barrel 121 increases the contact length between the second air supply pipe 160 and the first chute barrel 121, thereby facilitating the arrangement of more second air supply pipes 160.

[0025] In some embodiments, the first chute barrel 121 and the second chute barrel 122 are detachably connected, and the second air supply pipe 160 is fixedly connected to the second chute barrel 122. In the embodiment of the present application, the second air supply pipe 160 and the second chute barrel 122 can be designed as an integrated whole. Through the above arrangement, each first chute barrel 121 and the second chute barrel 122 can be independently mass-produced and installed after being transported to the factory, thereby reducing the manufacturing cost. On the other hand, when the first chute barrel 121 and the second chute barrel 122 are damaged, only the corresponding parts need to be damaged, without the need to dismantle the entire unloading chute 120.

[0026] In some embodiments, flanges are provided at both ends of the first chute barrel 121 and the second chute barrel 122, and airtight rubber rings are provided at the ends of the flanges, and the first chute barrel 121 and the second chute barrel 122 are connected by the flanges. In the embodiment of the present application, the first chute barrel 121 and the second chute barrel 122 can be stably connected as one through the flanges, and the airtight rubber rings are used to enhance the airtightness of the connection.

[0027] In some embodiments, there are multiple buffer gas boxes 140, and the multiple buffer gas boxes 140 are respectively arranged on each side wall of the material discharge chute 120. In the embodiment of the present application, through the above arrangement, the cleaning function can be realized on each side of the material discharge chute 120, thereby greatly improving the cleaning efficiency.

[0028] In some embodiments, a maintenance door 180 is provided on one side wall of the material discharge chute 120. In the embodiment of the present application, the maintenance door 180 is provided to facilitate maintenance of the material discharge chute 120 and manual clearing of blockage.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
