[0029] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] Example 1

[0034] Please refer to Figure 1 、 Figure 2 and Figure 3 A coal gangue fuel mixing device includes a mixing drum 1, a closing member is provided above the mixing drum 1, an introduction member is provided at the top of the closing member, a rotating member is provided inside the mixing drum 1, a plurality of stirring members are provided outside the rotating member, a support member is provided at the bottom end of the mixing drum 1, a plurality of guide members are provided on the inner wall of the mixing drum 1, the guide members are used to guide the material located near the inner wall of the mixing drum 1 to the middle, a receiving member is provided inside the supporting member, and a disassembly member is provided at the front end of the receiving member.

[0035] Further, such as Figure 1 and Figure 6 As shown, the closure includes a top cover 201 fixed to the top of the mixing drum 1. An inlet is provided at the top of the top cover 201 for pouring the gangue and other combustible substances or materials such as coal, biomass, etc. that need to be mixed into the interior of the mixing drum 1 from the inlet.

[0036] Further, such as Figure 1 and Figure 6 As shown, the introduction member includes a funnel 202 fixed to the top of the top cover 201. The top of the funnel 202 can be covered to prevent debris from entering when mixing materials. The interior of the funnel 202 is connected to the inlet.

[0037] Further, such as Figure 3As shown, the guide member includes a guide plate 401 fixed to the inner wall of the mixing drum 1. Several guide plates 401 are fixed to the inner wall of the mixing drum 1. The guide plate 401 is triangular when viewed from the top, and its three sides have a certain curvature. One side of the guide plate 401 is a curved surface that is in close contact with the inner wall of the mixing drum 1, and the other two sides of the guide plate 401 are curved surfaces facing the side away from the center of the mixing drum 1. In this way, the end of the guide plate 401 is close to the center of the mixing drum 1. When there is material on the inner wall of the mixing drum 1, the power driven by the rotating shaft 301 and the stirring blade 302 is used to make the material close to the curved surface on one side of the guide plate 401. The material is guided to the end of the guide plate 401 through the curved surface and is brought into the position of the stirring blade 302 for stirring again, thereby improving the stirring effect.

[0038] Further, such as Figure 3 and Figure 4 As shown, the rotating member includes a rotating shaft 301 rotatably connected to the bottom end of the mixing drum 1. The rotating shaft 301 is used to drive a plurality of stirring members to rotate to stir and mix the materials.

[0039] Further, such as Figure 4 As shown, the stirring member includes a stirring blade 302 fixed to the side of the rotating shaft 301 , and the stirring blade 302 is used to stir the material through the rotating shaft 301 .

[0040] Example 2

[0041] The gangue fuel mixing device provided in Example 1 is further optimized. Specifically, Figure 4 and Figure 5 As shown, the stirring blade 302 is streamlined when viewed from the side, and one side of the stirring blade 302 is curved in a downward arc. The downward arc can be used to shovel more materials upward to prevent the materials from being unable to mix with the materials above. The other side of the stirring blade 302 is curved in an upward arc, so that when the stirring blade 302 rotates through the rotating shaft 301, the materials are shoveled upward through the downward arc and brought upward through the upward arc surface, so as to be mixed with the materials above again, making it easier for the materials to collide and mix during the stirring process, and cooperate with the guide plate 401 to form a more complex flow pattern in the cylinder, thereby improving the mixing efficiency and reducing the time required for mixing.

[0042] Further, such as Figure 4 and Figure 5 As shown, the bottom end of the stirring blade 302 is a plane. When the stirring blade 302 shovels the material onto the stirring blade 302, the stirring blade 302 will be subjected to a certain downward pressure. The bottom end of the stirring blade 302 lacks support, so that the structure of the stirring blade 302 is easily deformed by the downward pressure or even broken. By setting the bottom end as a plane, the connection area with the rotating shaft 301 is increased. At the same time, the plane of the bottom end of the stirring blade 302 can better contact the material below during stirring, thereby providing a certain supporting force to support the bottom end of the stirring blade 302.

[0043] The lower part of the stirring blade 302 close to the side of the upward arc is also curved. During stirring, the stirring blade 302 located at the bottom drives the raw materials to shovel upward, thereby increasing the supporting force of the plane below the stirring blade 302. When the material originally in contact with the bottom plane of the stirring blade 302 separates from the plane, it loses the support of the plane and will flow upward along the curved surface. According to the text description and the drawings, the shape of the stirring blade 302 is close to S-shaped when viewed from the side.

[0044] Example 3

[0045] The gangue fuel mixing device provided in Example 1 and Example 2 is further optimized, such as Figure 1 and Figure 2 As shown, the support member includes a support base 501 located at the bottom end of the mixing drum 1, and a mounting groove 502 is provided at the top of the support base 501. The mounting groove 502 is used to increase the connection surface with the mixing drum 1, so that it is more stable when supported by the support base 501. The mixing drum 1 is fixedly connected to the inside of the mounting groove 502. The front end of the mounting groove 502 is provided with a placement groove. The placement groove is used to place the container into the groove and collect the raw materials through the outlet. The bottom end of the mixing drum 1 and the bottom end of the mounting groove 502 are both provided with outlets. The outlet at the bottom end of the drum 1 is connected to the outlet at the bottom end of the mounting groove 502. A control valve is provided inside the mixing drum 1. The receiving part includes a receiving bucket 601 that is slidably connected to the placement groove. A number of rollers are provided at the bottom end of the receiving bucket 601. A handle 602 is provided at the front end of the receiving bucket 601. The receiving bucket 601 is pulled out from the placement groove through the handle 602. The disassembly part includes a fixing bar 701 located at the front end of the receiving bucket 601. Both ends of the fixing bar 701 are detachably connected to the support seat 501 and are detachably connected by screws.

[0046] Further, such as Figure 1 and Figure 6 As shown, a motor 303 is fixedly provided on the top of the top cover 201. The motor 303 is located on one side of the funnel 202 and the center of the top of the top cover 201. The output end of the motor 303 passes through the top cover 201 and is fixedly connected to the rotating shaft 301. When it is necessary to stir the material inside the mixing drum 1, the motor 303 is started to drive the rotating shaft 301 and the stirring blade 302 to rotate. After the material stirring is completed, the motor 303 is started to rotate in the opposite direction, so that the stirring blade 302, which was originally used to shovel the material upward, has its purpose reversed due to the reverse rotation, and is replaced by shoveling the material downward through the upward arc surface, providing a certain downward pressure for the material, so that the material can fall through the outlet faster.

[0047] The use process of the coal gangue fuel mixing device provided by the utility model is as follows:

[0048] When the materials need to be mixed, the materials are poured into the mixing drum 1 through the top cover 201, and then the motor 303 is started to rotate, driving the rotating shaft 301 and the stirring blade 302 to rotate and stir the materials. During stirring, the materials located at the edge of the inner wall of the mixing drum 1 are guided to the center by the curved surface on the guide plate 401; the downward curved surface of the stirring blade 302 shovels the materials upward, so that they are shoveled upward and mixed with the materials above. The shape of the stirring blade 302 improves the mixing efficiency.

[0049] After mixing, it needs to be discharged through the outlet. The outlet switch is opened through the control valve, and then the motor 303 is started to reverse, driving the rotating shaft 301 and the stirring blade 302 to rotate in the opposite direction. The upward and downward arc surfaces of the stirring blade 302 increase the downward pressure of the material, and the arc surface of the guide plate 401 is used to gather the material in the middle direction, avoiding the material from remaining in the corners inside the mixing drum 1 as much as possible, so that it can flow from the outlet to the inside of the storage barrel 601 faster; when the storage barrel 601 needs to be pulled out from the inside of the support seat 501, the fixing bar 701 is removed to make the storage barrel 601 lose its obstruction, thereby pulling the storage barrel 601 out.
