Description

Technical Field

[0001] This utility model belongs to the field of mortar processing technology, and in particular relates to a mortar mixing device. Background Technology

[0002] Mortar is a building material used in various construction projects. Because mortar is used in large quantities, and different types of mortar have different properties, such as varying strengths or grade, the consistency of mortar often differs depending on its properties.

[0003] Because mortar consumption is very high, mortar is often produced in a prefabricated manner during engineering construction. That is, mortar is produced in a production workshop through prefabrication, and then transported to the construction site.

[0004] In the process of precast mortar production, mortar mixes are often fed into tanks. Traditional tank mixing structures are mostly bottom mixing, which is more effective for mortars with high water content. However, for high-standard mortars and mortars with low water content, which have high viscosity, traditional bottom mixing cannot fully mix the mortar. Therefore, in order to obtain a better mixing effect, the current practice is to increase the mixing time or reduce the amount of mixes in the tank.

[0005] Obviously, the above methods result in a lower mortar preparation effect, which is reflected in the excessively long mixing time and the excessively low mixing amount. Since mortar is prefabricated and needs to be transported to the construction site quickly after production, the mortar material needs to be processed in a short time.

[0006] Therefore, in actual production processes, traditional mixing tanks have the aforementioned structural defects, especially in the processing of special mortars containing adhesives, where the processing effect is not ideal.

[0007] Therefore, the current practice is to improve the mixing structure to achieve a more ideal mixing effect in order to facilitate the high-efficiency preparation of mortar. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide a mortar mixing device.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A mortar mixing device includes a mixing tank, and a mixing mechanism is assembled and connected inside the mixing tank. The mixing mechanism includes several mixing units, and the mixing units are fixedly connected to each other by several connecting frames.

[0011] Each mixing unit includes a mounting rod fixedly installed on a connecting frame. Several staggered mixing plates are mounted and connected to the mounting rod, and mixing tooth structures are fixedly connected to the mixing plates. The staggered mixing plates are used to reduce mixing resistance and increase mixing effect during mortar mixing. The mixing tooth structure is used to refine the mortar material.

[0012] The mixing mechanism also includes a drive structure that drives the mixing unit to rotate.

[0013] Preferably, the mixing units are fixed together by a plurality of Y-shaped connecting frames arranged at vertical intervals;

[0014] The mounting rod passes through the Y-shaped connector.

[0015] Preferably, the drive structure includes a rotating shaft fixedly connected between the Y-shaped connecting frames; a drive motor is mounted on the top of the rotating shaft.

[0016] The bottom of the rotating shaft is rotatably connected to a bottom support bracket, and the two ends of the bottom support bracket are fixedly installed on the inner side wall of the mixing tank.

[0017] Preferably, the upper end of the rotating shaft is rotatably connected to an upper support bracket, and the drive motor is fixedly mounted on the upper support bracket; both ends of the upper support bracket are fixedly mounted on the mixing tank body.

[0018] Preferably, the longitudinal cross-sectional shape of the mixing plate is semi-circular;

[0019] The mixing teeth structure is welded to the curved side of the mixing plate.

[0020] Preferably, the mixing tooth structure includes an arc-shaped support welded to the mixing plate, and a plurality of arc-shaped mixing teeth are welded on the arc-shaped support; the tips of the mixing teeth are arranged outward.

[0021] Preferably, the upper and lower ends of the mixing plate are integrally formed with cylindrical mounting sleeves, which are fastened to the rotating shaft by bolts.

[0022] Preferably, an annular seat is fixedly connected to the top inlet of the mixing tank; several screw conveyors are installed on the annular seat, with the discharge end of the screw conveyor facing into the mixing tank.

[0023] Preferably, a bottom support frame is fixedly connected to the lower end of the mixing tank.

[0024] This utility model has the following beneficial effects:

[0025] 1. During operation, the rotating mixing plates (made of 1.5cm thick steel plates cut into semi-circular shapes) are staggered, thus reducing mixing resistance during the mixing process. Furthermore, every three mixing units form a mixing surface, and multiple sets of three mixing units are spaced vertically, achieving layered mixing at different heights, further improving the mixing effect. The staggered arrangement of the mixing plates between the mixing layers also minimizes agitation resistance.

[0026] Therefore, this method greatly improves the mixing effect of mortar materials, especially solving the mixing and preparation of mortars with low moisture content, high viscosity, or special viscosity.

[0027] 2. During the operation, while mixing the materials, the arc-shaped support-mixing tooth structure welded on the mixing plate refines the mortar, especially for mortar with high viscosity. The arc-shaped support-mixing tooth structure further refines the mortar lumps and agglomerates in the mortar. Attached Figure Description

[0038] Example 1

[0039] like Figure 1-5 As shown, a mortar mixing device includes a mixing tank 1, which is similar to existing methods. The mixing tank 1 includes a cylindrical tank section and a conical section integrally formed at the bottom of the cylindrical tank section. A discharge pipe is installed at the bottom of the conical section.

[0040] In order to fully mix the materials in the tank, especially for mortars with high viscosity or special mortars with added adhesives, the mixing structure is improved to achieve the desired mixing effect.

[0041] Specifically, a mixing mechanism 4 is assembled and connected inside the mixing tank 1. The mixing mechanism 4 includes three mixing units 42 arranged in a ring around the perimeter. The mixing units 42 are fixedly connected to each other by several connecting brackets 43.

[0042] Specifically, each mixing unit 42 includes a mounting rod 421 fixedly mounted on a connecting frame 43 (specifically, the mixing units 42 are fixed together by a number of Y-shaped connecting frames 43 arranged at vertical intervals; the mounting rod 421 passes through the Y-shaped connecting frames 43).

[0043] Several staggered mixing plates 422 are mounted and connected to each mounting rod 421 (i.e., all mixing plates 422 on the mounting rod 421 should not overlap on the horizontal ground). The mixing plates 422 are distributed along the height direction of the cylindrical tank. In this way, the entire mixing tank 1 is fully mixed during the mixing process to match the mortar with high concentration and high viscosity.

[0044] During operation, the rotating mixing plates 422 (made from 1.5cm thick steel plates cut into semi-circular shapes) are staggered, thus reducing mixing resistance during the mixing process. Furthermore, every three mixing units 42 form a mixing surface, and multiple sets of three mixing units 42 are spaced vertically, achieving layered mixing at different heights, further improving the mixing effect. The staggered arrangement of the mixing plates 422 between mixing layers at different heights also minimizes stirring resistance.

[0045] Therefore, this method greatly improves the mixing effect of mortar materials, especially solving the mixing and preparation of mortars with low moisture content, high viscosity, or special viscosity.

[0046] Meanwhile, the aforementioned mixing mechanism 4 also includes a drive structure for driving the mixing unit 42 to rotate. Similar to existing methods, the drive structure includes a rotating shaft fixedly connected between the Y-shaped connecting frames 43; a drive motor is mounted on the top of the rotating shaft. A bottom support bracket 44 is rotatably connected to the bottom of the rotating shaft, and both ends of the bottom support bracket 44 are fixedly installed on the inner side wall of the mixing tank 1.

[0047] The upper end of the rotating shaft is rotatably connected to an upper support bracket 411, and the drive motor 41 is fixedly installed on the upper support bracket; both ends of the upper support bracket 411 are fixedly installed on the mixing tank body 1.

[0048] The upper and lower ends of the above-mentioned mixing plate 422 are integrally formed with cylindrical mounting sleeves 4223, which are fastened to the rotating shaft by bolts.

[0049] Example 2

[0050] like Figure 1-5 As shown, in this embodiment, based on the structure of Embodiment 1, a mixing tooth structure is fixedly connected to the mixing plate 422; the mixing tooth structure is used to refine the mortar material. The mixing tooth structure is welded to the arc-shaped side of the mixing plate 422.

[0051] The mixing tooth structure includes an arc-shaped bracket 4221 welded to the mixing plate 422, and a number of arc-shaped mixing teeth 4223 are welded on the arc-shaped bracket 4221; the tips of the mixing teeth 4223 are arranged outward.

[0052] During the operation, while mixing the materials, the arc-shaped support 4221-mixing teeth 4223 structure welded on the mixing plate 422 refines the mortar, especially for mortar with high viscosity. The arc-shaped support 4221-mixing teeth 4223 structure further refines the mortar lumps and agglomerates in the mortar.

[0053] Example 3

[0054] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, an annular seat is fixedly connected to the top inlet of the mixing tank 1; several screw conveyors 2 are installed on the annular seat (the screw conveyors 2 are fixed to the annular seat by support brackets 21), and the discharge end of the screw conveyors 2 faces into the mixing tank 1. During operation, the screw conveyors automatically add materials, including auxiliary materials (such as adhesives, rubber, crushed stone, etc.), into the tank during the mixing of mortar.

[0055] This method allows for simultaneous material feeding during operation. During production, the screw conveyor can also add material to the tank without stopping the mixing process. In actual operation, the screw conveyor's feed hopper is located at the bottom of the storage tank's discharge port, automatically transporting material from the storage tank to the mixing tank 1, thus significantly improving production efficiency.

[0056] Similar to existing methods, a bottom support frame 3 is fixedly connected to the lower end of the mixing tank 1. A bracket structure 31 is welded to the bottom of the bottom support frame 3 to support the entire tank.

[0057] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
