Description

Technical Field

[0001] This utility model relates to the technical field of ore smelting equipment, specifically an ore mixing machine for ore smelting. Background Technology

[0002] Ore smelting is the process of processing ores containing metals or other useful substances to extract the target metals or substances. In the ore smelting process, it is necessary to use a corresponding ore mixer to uniformly mix ores of different components, additives and chemicals, to ensure that the various components in the ore are evenly distributed during the smelting process, so as to obtain an ideal ore mixture.

[0003] An existing patent (publication number: CN222266790U) discloses an ore mixer for ore smelting. By installing buffer pads on both sides of the inner wall of the mixer body, the ore raw materials can be prevented from colliding with the inner wall during the mixing process, which results in greater noise. This gives the ore mixer an inner wall protection structure. The cooperation between the collection box and the extension frame can block and seal the discharge port, giving the ore mixer an anti-splash structure.

[0004] However, the above-mentioned technical solutions still have certain defects. When some larger-sized ores are mixed into the mixture, it will affect the reaction speed and effect of smelting. Larger-sized ores are heated unevenly in the furnace, and it is easy for the outside to melt while the inside has not fully reacted, resulting in uneven composition of smelting products and affecting product quality. In addition, excessively large ore particles may also cause poor permeability of the material layer in the furnace, affecting gas flow, causing furnace condition fluctuations, further interfering with the subsequent smelting process, reducing smelting efficiency and product qualification rate. Therefore, an ore mixer for ore smelting is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an ore mixing machine for ore smelting, so as to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An ore mixing machine for ore smelting includes an outer cylinder and an inner cylinder. A fixed frame is fixedly installed at the bottom of the inner cylinder and is fixedly connected to the bottom of the outer cylinder. A hemispherical screening screen is fixedly installed on the upper surface of the fixed frame and inside the inner cylinder. A feeding metal mesh is provided between the fixed frame and the bottom of the outer cylinder. A conveying assembly is provided between the outer cylinder and the inner cylinder. The conveying assembly includes a conveying cylinder fixedly connected between the outer cylinder and the inner cylinder. A rotating shaft is longitudinally provided inside the conveying cylinder, and a spiral blade is fixedly sleeved on the outer wall of the rotating shaft.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] In one embodiment, such as Figures 1-6 As shown, an ore mixer for ore smelting includes an outer cylinder 100 and an inner cylinder 101. A fixing frame 120 is fixedly installed at the bottom of the inner cylinder 101, and the fixing frame 120 is fixedly connected to the bottom of the outer cylinder 100. A hemispherical screening screen 130 is fixedly installed on the upper surface of the fixing frame 120 and inside the inner cylinder 101. A feeding metal mesh 140 is provided between the fixing frame 120 and the bottom of the outer cylinder 100. A feeding hopper 110 is fixedly installed at the top of the outer cylinder 100. A receiving box is connected to the bottom of the outer cylinder 100, directly below the feeding metal mesh 140 and the fixing frame 120. Four sets of equidistantly distributed support legs 150 are fixedly installed on the outer side of the bottom of the outer cylinder 100. A connection is provided between the outer cylinder 100 and the inner cylinder 101. The conveying assembly 300 includes a conveying cylinder 310 fixedly connected between the outer cylinder 100 and the inner cylinder 101. The conveying cylinder 310 has a rotating shaft arranged longitudinally inside, and a spiral blade 320 is fixedly sleeved on the outer wall of the rotating shaft. There are four sets of conveying cylinders 310, and the four sets of conveying cylinders 310 are equidistantly distributed between the outer cylinder 100 and the inner cylinder 101. Four sets of second motors 330 for driving the corresponding spiral blades 320 to rotate are fixedly installed on the top of the outer cylinder 100. The outer side of each set of conveying cylinders 310 is in contact with the outer wall of the inner cylinder 101. Each set of conveying cylinders 310 and the inner cylinder 101 have a corresponding size inlet 340 at the lower end and a corresponding size outlet 350 at the upper end.

[0032] In this embodiment, after the ore raw material is poured from the feed hopper 110 into the inner cylinder 101, it is crushed and mixed. A portion of the ore raw material of the appropriate size passes through the hemispherical screen 130 and the discharge metal mesh 140 and falls into the external receiving box. The remaining larger ore raw material enters the conveying cylinder 310 through the feed inlet 340. The controller starts the second motor 330, and the output end of the second motor 330 drives the rotating shaft and the spiral blade 320 to rotate, thereby conveying the ore raw material to the discharge outlet 350 at the top of the conveying cylinder 310. Then it re-enters the inner cylinder 101 for secondary crushing and mixing, thereby achieving uniform mixing and improving the quality and efficiency of subsequent ore smelting.

[0033] In one embodiment, such as Figure 1 and Figure 4 As shown, the inner cavity of the inner cylinder 101 is equipped with a crushing and mixing assembly 200 for crushing and mixing ore raw materials. The crushing and mixing assembly 200 includes a rotating column 210 longitudinally arranged in the inner cavity of the inner cylinder 101. The top of the hemispherical screening screen 130 is sleeved on the outer wall of the rotating column 210 through a bearing. Several equally spaced crushing plates 220 are fixedly sleeved on the outer wall of the rotating column 210. A first motor 230 for driving the rotating column 210 to rotate is fixedly installed on the top of the outer cylinder 100. The operator starts the first motor 230 through the controller. Motor 230, the output end of the first motor 230 drives the rotating column 210 to rotate, thereby driving the crushing plate 220 to crush, stir and mix the ore raw materials. These ore raw materials fall onto the surface of the hemispherical screen 130 and the feeding metal mesh 140. The ore raw materials that meet the standard pass through the hemispherical screen 130 and the feeding metal mesh 140 and fall into the receiving box. The ore raw materials that do not meet the size are conveyed to the top of the inner cavity of the inner cylinder 101 by the conveying component 300 to continue to be crushed and mixed by the crushing plate 220.

[0034] In one embodiment, such as Figure 5 and Figure 6 As shown, the inner wall of the inner cylinder 101 is fixed with several equidistantly distributed guide plates 240 from top to bottom, and each guide plate 240 is set between two adjacent sets of crushing plates 220. Each guide plate 240 and crushing plate 220 has uniformly distributed through holes 250. The guide plate 240 is annular and inclined to the vertical direction. The inclined annular guide plate 240 allows the falling ore raw material to slide down along the inclined direction of the guide plate 240, increasing the crushing and stirring time of the ore raw material in the inner cylinder 101. At the same time, by opening through holes 250 on the crushing plate 220 and the guide plate 240, the fluidity of the ore raw material is increased, realizing full stirring and uniform mixing of the ore, thereby improving the quality and efficiency of ore smelting.

[0035] In one embodiment, such as Figure 4 and Figure 5 As shown, an arc-shaped scraper 360 is fixedly sleeved on the outer wall of the rotating column 210 and fits against the outer side of the hemispherical screening screen 130. The end of the arc-shaped scraper 360 away from the rotating column 210 fits against the upper surface of the feeding metal mesh 140. As the rotating column 210 rotates, it drives the arc-shaped scraper 360 to scrape the outer surface of the hemispherical screening screen 130 and the feeding metal mesh 140, so that the ore raw material does not accumulate on its surface, thereby increasing the feeding rate of the ore raw material. At the same time, through the rotation of the arc-shaped scraper 360, larger volumes of ore raw material are pushed from the feed inlet 340 into the conveying cylinder 310.

[0036] The above embodiment discloses an ore mixer for ore smelting, wherein larger ore raw materials enter the conveying cylinder 310 through the feed inlet 340. The controller starts the second motor 330, and the output end of the second motor 330 drives the rotating shaft and the spiral blade 320 to rotate, thereby conveying the ore raw materials to the discharge outlet 350 at the top of the conveying cylinder 310. Then, it re-enters the inner cylinder 101 for secondary crushing, stirring and mixing, thereby achieving uniform mixing and improving the quality and efficiency of subsequent ore smelting.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
