Description

TECHNICAL FIELD

[0001] The utility model relates to agitating unit technical field, concretely relates to a kind of agitating unit for dry-mixed mortar production. BACKGROUND

[0002] Dry-mixed mortar, also known as dry powder mortar or premixed mortar, is a granular or powdery mixture made by precise batching and uniform mixing in a professional factory. It is composed of cementitious materials (such as cement and gypsum), fine aggregates (such as quartz sand), mineral admixtures, and various high-performance chemical additives (such as redispersible latex powder and cellulose ether). During use, it only needs to be mixed with water in proportion at the construction site. Dry-mixed mortar has the advantages of stable quality, environmental protection, energy saving, and high construction efficiency, and is widely used in building masonry, plastering, floor leveling, tile sticking, and external wall insulation.

[0003] The production process of dry-mixed mortar mainly includes the core links of raw material storage and transportation, precise metering, efficient mixing, finished product storage and packaging. Among them, the mixing process is the key step to ensure the uniformity of product quality. In this process, various dry, powdery, and trace components need to be fully mixed in the agitating unit to ensure the consistency and stability of the final mortar product performance.

[0004] Currently, the production of dry-mixed mortar is mainly carried out by paddle-type mixers. The mixer mainly drives the paddles to exert a strong pushing force on the dry-mixed mortar mixture through a rotating shaft. However, this mixing method is not uniform, and in the axial area between adjacent paddles, the mixture is difficult to be effectively driven, forming a large mixing dead zone, resulting in over-mixing of part of the mixture and insufficient mixing of another part. SUMMARY

[0005] The utility model aims at the defects and deficiencies of the prior art, and provides an agitating unit for dry-mixed mortar production.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: an agitating unit for dry-mixed mortar production, comprising a mixing box, a mixing opening on the mixing box for placing the mixture, a stirring shaft arranged in the mixing opening of the mixing box, a driving mechanism arranged between the stirring shaft and the mixing box for driving the stirring shaft to rotate forward, and an arc-shaped stirring member fixedly arranged on the stirring shaft for repeatedly lifting and throwing the mixture when the stirring shaft rotates. The lower end of the mixing opening is an arc-shaped opening, and the center of the arc-shaped opening corresponds to the axis of the stirring shaft. The arc-shaped stirring member is provided with a stirring push plate on its outer periphery for pushing the mixture at the bottom of the mixing opening to move horizontally and mix when the stirring shaft rotates. The stirring push plate is spirally arranged on the outer surface of the arc-shaped stirring member.

[0007] A further improvement is that the stirring shaft and the arc-shaped stirring component are fixedly connected by a support rib.

[0008] A further improvement is that an arc-shaped chamfered surface is provided between the supporting rib and the arc-shaped mixing component to reduce the amount of mixed material residue at the junction of the supporting rib and the arc-shaped mixing component.

[0009] A further improvement is that the stirring pusher plate is an arc-shaped plate.

[0010] A further improvement is that the drive mechanism is a servo motor with its fixed end located on the side end face of the mixing tank and its output end connected to the mixing shaft.

[0011] A further improvement is that the lower end face of the mixing tank is an arc surface.

[0012] A further improvement is that the lower end of the mixing tank is provided with a support base for supporting the mixing tank on a plane.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: After the mixture is introduced from the mixing port, the mixing shaft is driven to rotate in the forward direction by the driving mechanism, thereby driving the arc-shaped mixing component to rotate in the mixing port. The mixture can enter the arc-shaped mixing component through the opening. Through the repeated rotation of the arc-shaped mixing component, the mixture is repeatedly scooped up and thrown down. The mixing pusher plate pushes the mixture at the bottom of the mixing port to move horizontally and mix. By performing horizontal pushing and mixing actions while scooping up and throwing down the mixture, the mixing effect of the mixture in the mixing box is improved. Compared with the traditional paddle mixer, the mixing effect of the mixture is more uniform, and there is less likelihood of mixing dead zones. It is also less likely to cause some parts of the mixture to be over-mixed while others are under-mixed. Attached Figure Description

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] See Figures 1 to 5 As shown, the technical solution adopted in this specific embodiment is: a mixing device for dry-mixed mortar production, including a mixing box 1, a mixing port 2 opened on the mixing box 1 for placing the mixture, a mixing shaft 3 disposed on the mixing box 1 and located inside the mixing port 2, a driving mechanism disposed between the mixing shaft 3 and the mixing box 1 for driving the mixing shaft 3 to rotate in the forward direction, and an arc-shaped mixing component 4 fixedly disposed on the mixing shaft 3 for repeatedly scooping up and throwing the mixture when the mixing shaft 3 rotates. The lower end of the mixing port 2 is an arc-shaped opening, and the center of the arc-shaped opening corresponds to the axis of the mixing shaft 3. The outer periphery of the arc-shaped mixing component 4 is provided with a mixing push plate 5 for pushing the mixture at the bottom of the mixing port 2 to move horizontally and mix when the mixing shaft 3 rotates. The mixing push plate 5 is spirally disposed on the outer surface of the arc-shaped mixing component 4.

[0023] Arc-shaped stirring element 4 Figure 4 and Figure 5 As shown, the center of the arc-shaped stirring element 4 corresponds to the circular position of the stirring shaft 3. One side of the arc-shaped stirring element 4 is open, allowing the mixture to enter through this opening when the arc-shaped stirring element 4 rotates. A space is formed between the two end faces of the arc-shaped stirring element 4 and the inner wall of the mixing chamber 1, providing a channel for the movement of the mixture within the mixing chamber, thereby improving the mixing effect. The stirring pusher 5 is spirally arranged along the outer arc-shaped surface of the arc-shaped stirring element 4, extending from one end of the arc-shaped stirring element 4 to the other end. When it is necessary to remove the mixed mixture, the mixing chamber 1 can be tilted to allow the mixture to be removed from the stirring port 2. Alternatively, an opening can be made at the side end or bottom of the mixing chamber 1, through which the mixture can be discharged from the stirring port 2.

[0024] The stirring shaft 3 and the arc-shaped stirring component 4 are fixedly connected by a support rib 6. The support rib 6, the stirring shaft 3, and the arc-shaped stirring component 4 can be integrally formed, or the support rib 6 and the arc-shaped stirring component 4 can be integrally formed and then the support rib 6 can be welded to the stirring shaft 3.

[0025] An arc-shaped chamfered surface 7 is provided between the supporting rib 6 and the arc-shaped stirring component 4 to reduce the amount of mixed material residue at the junction of the supporting rib 6 and the arc-shaped stirring component 4.

[0026] The stirring pusher plate 5 is an arc-shaped plate. For example... Figures 1 to 5 As shown, both side ends of the stirring pusher plate 5 are arc-shaped surfaces, and the gap between the end of the stirring pusher plate 5 and the arc-shaped opening is between 10-100mm. When the stirring pusher plate 5 rotates with the arc-shaped stirring component 4, the arc-shaped surface of the arc plate enhances the driving effect on the horizontal movement of the mixing material.

[0027] The driving mechanism is a servo motor 8 with its fixed end located on the side end face of the mixing tank 1 and its output end connected to the mixing shaft 3. The output end of the servo motor 8 is connected to one end of the mixing shaft 3 via a coupling. The fixed end is mounted on the side end face of the mixing tank 1 by bolts. The mixing shaft 3 and the mixing tank 1 are rotatably and fixedly connected by bearings.

[0028] The lower end face of the mixing tank 1 is an arc surface.

[0029] The lower end of the mixing tank 1 is provided with a support base 9 for supporting the mixing tank 1 on a plane.

[0030] The working principle of this utility model is as follows: After the mixture is introduced into the mixing port 2, the stirring shaft 3 is driven to rotate in the forward direction by the servo motor 8, thereby driving the arc-shaped stirring piece 4 to rotate in the mixing port 2. The mixture can enter the arc-shaped stirring piece 4 through the opening. Through the repeated rotation of the arc-shaped stirring piece 4, the mixture is repeatedly scooped up and thrown down. The mixing push plate 5 pushes the mixture at the bottom of the mixing port 2 to move horizontally and mix. By scooping up and throwing down the mixture while performing horizontal pushing and mixing actions, the mixing effect of the mixture in the mixing box 1 is improved. Compared with the traditional paddle mixer, the mixing effect of the mixture is more uniform, and there is less likelihood of mixing dead zones. It is also less likely to cause some parts of the mixture to be over-mixed while others are under-mixed.
