Description

Technical Field

[0001] This utility model belongs to the field of mining equipment technology, and in particular relates to a horizontal compound mixer. Background Technology

[0002] In infrastructure construction and mine filling, mixers play a crucial role as key production equipment. The mixing performance of a mixer directly affects its economic efficiency and the quality of the finished product. Existing mixers used in infrastructure and mining typically employ a co-directional spiral propulsion mixing method. This involves several spirally advancing mixing blades arranged circumferentially along the mixing shaft in the direction of propulsion. The material is propelled axially and discharged directly through the outlet. Generally, with a fixed mixing time, a longer mixing stroke and more mixing cycles result in better mixing. Therefore, most existing mixers improve mixing efficiency by lengthening the mixing shaft (which leads to a larger overall size, making transportation inconvenient, increasing floor space, and raising production and transportation costs), increasing the number of mixing blades, or modifying the blade structure. However, the essence remains a single axial mixing process that cannot form a material pool. Material may be discharged directly from the outlet located below the mixer without sufficient mixing. In actual use, due to limitations in materials, processing technology, cost, and site availability, it is often impossible to increase the length of the mixing shaft or the number of mixing blades. Furthermore, improvements to the structure of the mixing blades cannot increase the mixing stroke, thus failing to achieve the most satisfactory mixing effect. Utility Model Content

[0003] The present invention aims to overcome the shortcomings of the prior art and provide a horizontal compound mixer.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] The horizontal compound mixer includes a horizontal mixer body (100), the inner cavity of the mixer body (100) is a mixing chamber (101), and a baffle is provided in the mixing chamber (101) near the discharge end to form a material pool (106) at the discharge end of the mixing chamber (101); a mixing shaft (102) is provided in the mixing chamber (101), and a mixing blade (103) is provided on the mixing shaft (102). One end of the mixing shaft (102) is connected to the front end of the mixing body (100), and the other end passes through the rear end of the mixing body (100) and is connected to the mixing body (106). 0) The drive mechanism (104) outside is connected; the material conveying device (300) is inclined at the discharge end of the material pool (106), and the discharge port (105) is provided on the outside of the discharge end of the material pool (106); the horizontal compound mixer also includes at least one spiral stirring device (200) arranged along the axis of the stirring shaft (102), the upper part of the spiral stirring device (200) is driven and installed on the top of the mixer body (100), the lower part of the spiral stirring device (200) extends into the stirring chamber (101), and the lower part of the spiral stirring device (200) is provided with blades.

[0006] Preferably, the material conveying device (300) is a scraper conveyor.

[0007] Preferably, the material conveying device (300) is a screw conveyor.

[0008] Preferably, the drive mechanism (104) is a motor.

[0009] Preferably, the stirring chamber (101) is provided with two parallel stirring shafts (102).

[0010] More preferably, the spiral stirring device (200) is arranged in the middle of the two stirring shafts (102).

[0011] The present invention will be further described below:

[0012] The horizontal compound mixer described in this utility model is mainly used for material mixing in mining and other fields. Unlike traditional mixers that only push material along the axial direction, this utility model arranges one or more material mixing spiral devices along the mixing shaft. The material is propelled axially by the rotating mixing shaft blades. When it encounters the mixing spiral blades, the spiral blades exert an upward lifting force perpendicular to the mixing shaft, causing the material to move in an additional direction, thus providing a three-dimensional mixing effect. In this way, without changing the length of the mixing shaft, that is, within the same conveying stroke, the material receives more mixing cycles and a longer mixing stroke, thereby improving the mixing effect. At the same time, due to the presence of a material tank, the material can be more thoroughly mixed within the mixing tank.

[0013] In this invention, two stirring shafts are provided, which are parallel to each other. A stirring spiral device is arranged at intervals along the material propulsion direction, with the stirring spiral devices positioned between the two parallel stirring shafts. The more stirring spiral devices, the better, without increasing the length of the stirring shafts.

[0014] In summary, based on existing mixers, this invention considers that if the mixing time and conveying stroke are constant throughout the mixing process, adding one or more mixing spiral devices can allow the material to undergo an upward lifting process during its propulsion along the mixing shaft. This adds a direction of material movement, thereby improving the mixing effect. Furthermore, the inclusion of a material pool increases the residence time of the material within the pool, allowing for more thorough mixing and further enhancing the mixing effect.
