[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0020] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] like Figure 1 As shown, an automatic anthracite conveying device provided by an embodiment of the present application is now described. The automatic anthracite conveying device comprises a storage bin 1, a crusher 2 and a conveying tank 3 installed on a frame. The first discharge pipe at the bottom of the storage bin 1 is connected to the crusher 2, and a gate valve 4 and a quantitative feeding valve 5 are provided on the first discharge pipe in sequence. The second discharge pipe at the bottom of the crusher 2 is connected to the conveying tank 3, and a discharge valve 6 is provided on the second discharge pipe; an air intake pipe 7 and an air intake valve 8 are provided on one side of the bottom of the conveying tank 3, and the air intake pipe 7 is connected to a compressed air supply device or a blower for blowing air into the conveying tank 3; a powder conveying pipe 9 and a conveying valve 10 are provided on the other side of the bottom of the conveying tank 3, and the powder conveying pipe 9 is connected to a fixed-point batching bin 11, and the airflow fed by the air intake pipe 7 feeds the pulverized coal into the fixed-point batching bin 11 through the powder conveying pipe 9.

[0023] Specifically, the height of the air inlet pipe 7 is lower than that of the conveying pipe, so that it is convenient for the airflow to drive the pulverized coal when it flows from bottom to top. The gate valve 4 is an electric gate valve, which is used to control the outflow of anthracite so as to control the outflow amount. The quantitative feeding valve 5 is a star-shaped feeding valve, which is used for uniform quantitative feeding. The crusher 2 is a double-roll crusher, which is used to crush the granular anthracite to a particle size of ≤5mm. The discharge valve 6 is an electric air lock ash discharge valve, which is used to uniformly flow the crushed pulverized coal into the conveying tank 3 and ensure that the air in the conveying tank 3 does not flow back into the crusher 2. The air outlet of the fixed-point batching bin 11 is provided with a dust collector 12 to prevent dust from escaping into the working environment. A filter screen 13 is provided on the top of the storage bin 1, and the mesh size of the filter screen 13 is 80mm. When the anthracite is unloaded into the storage bin 1, the larger coarse particles, floccules and other impurities are first filtered and removed through the filter screen 13.

[0024] The operation process of the anthracite automatic conveying device is as follows: the anthracite is first unloaded into the storage bin 1 for storage, and during storage, the coarse particles and flocculent impurities are first removed through the filter screen 13. When conveying anthracite, according to the demand of the fixed point position, the gate valve 4 is opened to allow the anthracite to flow into the quantitative feeding valve 5 for weighing, and then the anthracite is crushed in the crusher 2 to a particle size of ≤5mm, and then enters the transport tank through the discharge valve 6, the air intake valve 8 and the conveying valve 10 are opened, and the air intake pipe 7 begins to pass compressed air into the transport tank 3 to form an airflow. When the airflow passes through the conveying tank 3, the pulverized coal is sent to the fixed-point batching bin 11 through the powder delivery pipe 9, and the airflow is discharged from the fixed-point batching bin 11 through the air outlet after dust removal by the dust collector 12, and the pulverized coal remains in the fixed-point batching bin 11, thereby completing the quantitative and fixed-point precise conveying of anthracite.

[0025] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
