Description

Technical Field

[0001] This utility model relates to the field of lightweight plastering processing technology, specifically to a raw material mixing device for lightweight plastering gypsum processing. Background Technology

[0002] Lightweight plaster gypsum is a type of mortar made primarily from building gypsum powder and vitrified microspheres, with the addition of other auxiliary materials and admixtures. Its density is lower than ordinary gypsum mortar, hence it is also known as lightweight gypsum mortar or expanded perlite mortar. It features lightweight, fire resistance, moisture resistance, ease of processing, and simple installation. It is mainly used for smoothing and insulating interior walls and floors (such as aerated concrete blocks, brick walls, concrete walls, and roofs) in dry areas. During the mixing process, the raw materials are mostly in powder form. Commonly available mixing equipment for lightweight plaster gypsum processing has poor mixing efficiency, cannot adjust the mixing angle of the mixing blades according to the proportions and production needs, and cannot change the mixing effect of the materials as required. This issue urgently needs to be addressed. Utility Model Content

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Depend on Figures 1 to 6 The present invention includes a mixing vessel 1, a mixing shaft 2 rotatably connected inside the mixing vessel 1, a plurality of rotating shafts 3 evenly distributed along its vertical direction rotatably connected to the mixing shaft 2, a mixing blade 4 fixedly connected to the outside of the rotating shaft 3, a waist-shaped plate 5 fixedly connected to the other end of the rotating shaft 3, a connecting groove 6 provided on the waist-shaped plate 5, a lifting rod 7 coaxially provided in the middle of the mixing shaft 2 that can move up and down, a plurality of L-shaped connecting pins 8 corresponding one-to-one with the mixing blades 4 fixedly connected to the lifting rod 7, the connecting pins 8 being located in the connecting groove 6 on their corresponding sides, a plurality of U-shaped mixing rods 9 evenly distributed along its circumference fixedly connected to the outer end of the mixing shaft 2, the middle part of the mixing rod 9 being able to contact the inner wall of the mixing vessel 1, and a plurality of horizontal bars evenly distributed along its vertical direction fixedly connected to the outer wall of the mixing rod 9.

[0021] like Figures 1 to 6 As shown, a mixing vessel 1 is set up to mix lightweight plaster. A mixing shaft 2, lifting rod 7, rotating shaft 3, mixing blade 4, waist-shaped plate 5, connecting groove 6, and connecting pin 8 are included. The lifting rod 7, through the connecting pin 8 and connecting groove 6, drives the waist-shaped plate 5 and rotating shaft 3 to rotate, achieving uniform rotation of the mixing blade 4. This allows for changing the mixing angle of the mixing blade 4. Since changes in the mixing angle affect the generated shear force, thus affecting the mixing of materials, the angle can be changed as needed. Adjusting the angle of the mixing blade 4 can also change the flow pattern of the physical fluid, thereby affecting the mixing efficiency. An appropriate angle can improve the interaction between materials and promote uniform mixing. The mixing rod 9 and crossbar expand the mixing range, reduce dead zones, and prevent insufficient mixing.

[0022] A drive motor 10 is fixedly connected to the upper end of the stirring vessel 1. A helical gear 11 is fixedly connected to the output end of the drive motor 10. A bevel gear 12 meshes with the lower side of the helical gear 11. The lower end of the bevel gear 12 is fixedly connected to the stirring shaft 2 on the same axis. The bevel gear 12 is slidably connected to the lifting rod 7.

[0023] like Figure 5As shown, the drive motor 10, helical gear 11 and spur gear are configured so that the drive motor 10 can drive the stirring shaft 2 to rotate, and then the stirring blade 4 and stirring rod 9 can be used to stir the internal powder, thus providing power.

[0024] The upper end of the mixing vessel 1 is fixedly connected to a protective shell 13, and a hydraulic rod 14 is provided inside the protective shell 13. The lower end of the hydraulic rod 14 is fixedly connected to the mixing vessel 1.

[0025] like Figures 1 to 3 As shown, a protective shell 13 is provided to protect the internal structure, and a hydraulic rod 14 is provided to provide power for the lifting of the lifting rod 7. At the same time, the hydraulic rod 14 has a self-locking capability, which can fix the position of the moving frame 15 after stopping, preventing it from moving at will.

[0026] The output end of the hydraulic rod 14 is fixedly connected to an inverted U-shaped movable frame 15. A sliding rod 16 is fixedly connected to the upper side wall of the protective shell 13. The movable frame 15 and the sliding rod 16 are slidably connected. Inclined grooves 17 with the front lower and rear upper sides are respectively opened on the left and right sides of the movable frame 15. A lifting ring 18 is rotatably connected to the upper end of the lifting rod 7. Sliding pins 19 that can be inserted into the corresponding inclined grooves 17 are fixedly connected to the left and right sides of the lifting ring 18.

[0027] like Figures 2 to 6 As shown, the movable frame 15, inclined groove 17, lifting ring 18 and sliding pin 19 are provided so that the movement of the movable frame 15 can drive the lifting rod 7 to rise and fall through the action of the inclined groove 17, sliding pin 19 and lifting ring 18. The lifting ring 18 is rotatably connected to the lifting rod 7 to ensure that the lifting rod 7 can rotate normally. The sliding rod 16 is provided to fix the direction of movement of the movable rod and prevent it from tilting and becoming unusable.

[0028] The lower end of the stirring shaft 2 is fixedly connected to the auger blade 20, the lower end of the stirring vessel 1 is provided with a discharge port, the discharge port is fixedly connected to the discharge pipe 21, and the upper end of the stirring vessel 1 is fixedly connected to the feed hopper 22, which is connected to the interior of the stirring vessel 1.

[0029] like Figures 2 to 3 As shown, the screw conveyor blade 20 is set to facilitate material feeding and can also stir the powder at the bottom. The feeding port and feeding pipe 21 are set to discharge the internal material after the stirring is completed. The feeding pipe 21 is equipped with a material valve to control the flow of material. The feeding hopper 22 is set to facilitate material feeding.

[0030] The lower end of the mixing vessel 1 is fixedly connected to a support 23, and the lower end of the support 23 is fixedly connected to a plurality of legs evenly distributed along its circumference.

[0031] like Figures 1 to 2As shown, the bracket 23 is set to support the mixing vessel 1, and the support legs are equipped with shock-absorbing devices to provide support and damping, thereby improving the stability of the device.

[0032] An observation port is provided at the front end of the mixing vessel 1, and an explosion-proof glass plate is fixedly connected inside the observation port.

[0033] like Figure 1 As shown, an observation port and a glass plate are provided to facilitate observation of the interior, to monitor the internal stirring effect at any time, and to make timely records and judgments on whether the angle of the stirring blade 4 needs to be changed.

[0034] In use, the material is fed into the mixing vessel 1 through the feeding hopper 22. Then, according to the proportioning and mixing requirements, the hydraulic rod 14 is activated. The hydraulic rod 14 drives the moving frame 15 to move back and forth. Then, the lifting rod 7 is raised and lowered by the lifting ring 18 through the action of the sliding pin 19 and the inclined groove 17. The movement of the lifting rod 7 can rotate the rotating shaft 3 by the cooperation of the connecting pin 8 and the connecting groove 6, so as to change the angle of the mixing blade 4 and thus change the mixing effect according to the requirements.

[0035] After the angle of the stirring blade 4 is adjusted, the drive motor 10 is started. The drive motor 10 drives the stirring shaft 2 to rotate via the helical gear 11 and the bevel gear 12. The rotation of the stirring shaft 2 can drive the stirring blade 4, the stirring rod 9 and the auger blade 20 to rotate, thereby fully stirring the material in the mixing vessel 1. After stirring is completed, the drive motor 10 is started to reverse, and at the same time the material valve is opened, so that the auger blade 20 can be used to transport the internal material for easy discharge. At the same time, the discharge pipe 21 starts to transport the material after stirring to the outside of the mixing vessel 1, so as to achieve the purpose of rapid discharge and avoid the problem of blockage.

[0036] In this utility model, the drive motor 10 and the hydraulic rod 14 are both existing technologies and will not be described in detail here.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model.
