Description

Technical Field

[0001] This utility model relates to the field of rock wool board production technology, specifically to a mixing device for rock wool board production. Background Technology

[0002] Rock wool board, also known as rock wool insulation and decorative board, is an inorganic fiber board made from basalt as the main raw material through high-temperature melting and processing. During the production process, rock wool board requires mixing to ensure the uniformity of raw materials, optimize the formula ratio, and improve product performance and stability.

[0003] In existing technologies, mixing devices typically use multiple feed hoppers to deliver various raw materials into the device. Because the feed inlets of these hoppers are located at different positions within the device, different raw materials entering through these discrete feed inlets experience localized accumulation due to physical separation. This necessitates prolonged operation and stirring by the mixing device to achieve uniform distribution, significantly extending the mixing cycle, wasting considerable time, and resulting in low mixing efficiency. A mixing device for rock wool board production is needed to address these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mixing device for rock wool board production, so as to solve the problems mentioned in the background technology. This utility model has a reasonable structure, saves mixing time, and has high mixing efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mixing device for rock wool board production, comprising:

[0006] The housing has a mixing motor located at the center of its top. The output shaft of the mixing motor has a rotating shaft located inside the housing. The sidewall of the rotating shaft has multiple stirring plates. Feed hoppers are symmetrically arranged on the top of the housing.

[0007] The rotating shaft sidewall is fitted with a guide tube located above the stirring plate and with a closed top. The bottom of the feed hopper is provided with a connecting inclined tube that communicates with the inner wall of the guide tube. The rotating shaft sidewall is provided with spiral blades located inside the guide tube. A fixing column is provided between the guide tube sidewall and the inner wall of the shell.

[0008] Furthermore, a through hole is provided at the top of the guide tube, and the rotating shaft passes through the through hole.

[0009] Furthermore, a bearing is provided at the connection between the side wall of the rotating shaft and the top of the guide tube;

[0010] The top of the guide tube has an embedding hole that communicates with the through hole, and the bearing is located inside the embedding hole.

[0011] Furthermore, the side wall of the rotating shaft is provided with a tapered plate located below the guide tube.

[0012] Furthermore, the side wall of the feed hopper is provided with a limiting ring located at the top of the housing, and the limiting ring is connected to the housing with bolts.

[0013] Furthermore, a discharge pipe is provided at the bottom of the housing, and a discharge valve is provided at the bottom of the discharge pipe.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows:

[0015] This invention utilizes a mixing motor to drive a spiral blade, which in turn moves multiple raw materials downwards along a guide pipe. This allows the raw materials to flow into the housing from a single location. Under the action of a stirring plate, the raw materials flowing into the housing are agitated and stirred, improving the uniformity of the dispersion of the various raw materials, saving mixing time, and increasing mixing efficiency.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown, this utility model provides a technical solution: a mixing device for rock wool board production, comprising:

[0025] The housing 1 has a mixing motor 3 located at the center of the top of the housing 1. The output shaft of the mixing motor 3 has a rotating shaft 6 located inside the housing 1. Multiple stirring plates 11 are provided on the side wall of the rotating shaft 6. Feed hoppers 2 are symmetrically arranged on the top of the housing 1.

[0026] The side wall of the rotating shaft 6 is fitted with a guide pipe 8 located above the stirring plate 11 and with a closed top. The bottom of the feed hopper 2 is provided with a connecting inclined pipe 23 that communicates with the inner wall of the guide pipe 8. The side wall of the rotating shaft 6 is provided with a spiral blade 9 located inside the guide pipe 8. A fixing column 12 is provided between the side wall of the guide pipe 8 and the inner wall of the shell 1. This design uses symmetrically arranged feed hoppers 2 to deliver various raw materials through connecting inclined pipes 23 to the inside of the guide pipe 8, where they fall onto the spiral blades 9. The mixing motor 3 drives the rotating shaft 6, which in turn drives the spiral blades 9. The spiral blades 9 move the various raw materials downwards along the guide pipe 8, allowing them to flow into the shell 1 from a single location. Under the action of the stirring plate 11, the raw materials flowing into the shell 1 are agitated and stirred, improving the uniformity of dispersion, saving mixing time, and increasing mixing efficiency. Specifically, the various raw materials are initially mixed inside the guide pipe 8 under the action of the spiral blades 9, saving mixing time and improving mixing efficiency. The guide pipe 8 is fixed by the fixing column 12 to prevent it from rotating when the spiral blades 9 rotate.

[0027] Reference Figure 2 and Figure 3 The top of the guide tube 8 has a through hole, through which the rotating shaft 6 passes. This design facilitates the rotation of the rotating shaft 6 and avoids interference between the rotating shaft 6 and the guide tube 8.

[0028] Reference Figure 3 A bearing 7 is provided at the connection between the side wall of the rotating shaft 6 and the top of the guide tube 8;

[0029] The top of the guide tube 8 has an embedded hole that communicates with the through hole, and the bearing 7 is located inside the embedded hole. This design, through the bearing 7, improves the rotational stability at the connection between the rotating shaft 6 and the guide tube 8.

[0030] Reference Figure 2 , Figure 4 and Figure 5The side wall of the rotating shaft 6 is provided with a conical plate 10 located below the guide pipe 8. This design, through the conical plate 10, facilitates the uniform dispersion of various raw materials flowing out of the guide pipe 8 into the interior of the shell 1, thereby improving the uniformity of raw material dispersion.

[0031] Reference Figure 1 The side wall of the feed hopper 2 is provided with a limiting ring 21 located at the top of the housing 1, and a bolt 22 is provided at the connection between the limiting ring 21 and the housing 1. This design improves the stability of the connection between the feed hopper 2 and the housing 1.

[0032] Reference Figure 1 and Figure 2 The bottom of the shell 1 is provided with a discharge pipe 4, and the bottom of the discharge pipe 4 is provided with a discharge valve 5. This design facilitates material discharge through the discharge pipe 4 and the discharge valve 5; the lower inner wall of the shell 1 is provided with a downwardly recessed arc-shaped groove to facilitate the flow of raw materials.

[0033] Reference Figures 1-5 As an embodiment of this utility model: when it is necessary to mix multiple raw materials for the production of rock wool boards, the multiple raw materials are placed inside the symmetrical feed hopper 2, and the multiple materials enter the guide pipe 8 along the corresponding connecting inclined pipe 23 and fall onto the spiral blade 9.

[0034] The mixing motor 3 drives the rotating shaft 6 to rotate, which in turn drives the spiral blades 9 to rotate. The spiral blades 9 then move various raw materials downward along the guide pipe 8. During the downward conveying process of the spiral blades 9, the various raw materials are initially mixed, saving mixing time and improving mixing efficiency. This ensures that the various raw materials flow into the shell 1 from one location. Under the guidance of the conical plate 10, the various raw materials are evenly dispersed into the shell 1. Under the action of the stirring plate 11, the raw materials flowing into the shell 1 are agitated and stirred, further improving the uniformity of the dispersion of the various raw materials, saving mixing time, improving mixing efficiency, and enhancing the practicality of this utility model.
