Description

Technical Field

[0001] The invention relates to the technical field of castable mixing, in particular to a mixing device for castable production. Background Art

[0002] In the castable production process, the most commonly used mixing equipment is the castable mixer. After the equipment is powered on, the main mixing motor is activated via a start / stop switch with a protective function. Once the equipment reaches stable operation, the material to be mixed is added to the mixer's mixing bowl. Simultaneously, an appropriate amount of water is added to the mixing bowl via a water pump for thorough mixing. Once the material is evenly mixed, the feed gate is opened, and the mixer moves along the track, easily discharging the material to the target location. The mixer can freely move and stop on the working rails to meet different feeding requirements. Once the material in the mixer is completely discharged, the gate is closed, completing a mixing cycle.

[0003] In current castable mixing equipment, castables often adhere firmly to the inner wall of the mixing drum after mixing due to their strong adhesive properties. To thoroughly clean the mixing drum, operators often need to flush it with large amounts of liquid, which not only increases cleaning costs but also potentially wastes resources. Furthermore, the cleaning process itself is time-consuming and labor-intensive, requiring operators to invest significant time and energy, thus impacting overall production efficiency.

[0012] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0013] like Figure 1 - Figure 8 As shown, a mixing device for castable production is mainly composed of a stand 1, a mixing barrel 2, and a connecting seat 3, wherein the mixing barrel 2 is mounted on the stand 1 via the connecting seat 3. The upper opening of the mixing barrel 2 is connected to a movable annular seat 4 via a stop ball 5. The movable annular seat 4 is internally mounted with a mounting frame 6. A stabilizing bracket 14 extends from the upper middle section of the mounting frame 6. The upper end of the stabilizing bracket 14 is mounted with a drive motor 15. The output end of the drive motor 15 is connected to a stirring rod 16. The stirring rod 16 extends into the mixing barrel 2 to achieve mixing of the materials in the mixing barrel 2. This design allows the materials to be evenly mixed in the mixing barrel 2, thereby improving production efficiency and material quality.

[0014] The sidewalls of the mounting frame 6 are provided with a chute 9, within which an electric push rod 7 is mounted. Furthermore, an L-shaped frame 10 is provided within the mounting frame 6. The L-shaped frame 10 is inserted into the chute 9 via a connecting shaft 8 and connected to the electric push rod 7. A U-shaped frame 11 is connected between the two L-shaped frames 10. A fixed screw 12 is inserted into the opening of the U-shaped frame 11, and a scraper 13 is mounted between the two fixed screws 12. The electric push rod 7 drives the scraper 13 via the connecting shaft 8, the L-shaped frame 10, and the U-shaped frame 11, causing the scraper 13 to reciprocate within the mixing barrel 2, contacting the inner wall of the mixing barrel 2, thereby moving the material. This reciprocating motion ensures uniform distribution of the material within the mixing barrel 2, further enhancing the mixing effect.

[0015] Multiple connectors 3 are distributed in a circular pattern around the mixing drum 2. These connectors 3 are secured to the mixing drum 2 by welding, while bolts are used to secure them to the stand 1. Anti-slip rubber pads are installed at the joints between the connectors 3 and the stand 1. A crossbar is located at the lower end of the stabilizing bracket 14, extending into and securing the mixing drum 2. The mounting bracket 6 is placed on top of the crossbar, with a gap between the two. This structural design not only ensures the stability of the equipment but also facilitates maintenance and cleaning.

[0016] The movable annular seat 4 has a "mountain"-shaped cross-section. Its lower end is inserted into the mixing drum 2, with its side protrusions engaging the annular groove in the mixing drum 2. Multiple retaining balls 5 protrude from the middle of the movable annular seat 4, the lower ends of which engage the annular groove at the upper end of the mixing drum 2. This design ensures that the movable annular seat 4 is securely fixed to the mixing drum 2, while the retaining balls 5 ensure the stability of the mixing drum 2 during operation.

[0017] The mounting brackets 6 have a U-shaped cross-section. Two mounting brackets 6 are symmetrically positioned on the movable annular base 4 and secured with bolts. The electric push rods 7 on the movable annular base 4 are bolted to the mounting brackets 6. Nuts secure the telescopic ends of the push rods 7 to the connecting shaft 8. This structural design enables the push rods 7 to precisely control the movement of the scraper 13, achieving accurate mixing of the materials.

[0018] The L-shaped frame 10 and the mounting frame 6 are connected using a position-limiting mechanism. The central hole of the L-shaped frame 10 faces the chute 9. The connecting shaft 8 passes through the central hole of the L-shaped frame 10 and is secured with a nut. As the electric push rod 7 extends and retracts, the L-shaped frame 10 moves along the chute 9. This connection ensures the stability and precise movement of the L-shaped frame 10 within the chute 9.

[0019] The U-shaped frame 11 has circular holes at each end. Connecting shaft 8 is inserted into these holes and secured to the L-shaped frame 10 via nuts. A fixing screw 12 is inserted into a hole in the middle of the U-shaped frame 11 and secured with a nut and non-slip washer. The fixing screw 12 and scraper 13 can be adjusted up and down to vary the length of the scraper 13 extending into the mixing barrel 2. This design allows the scraper 13 to be adjusted based on the material characteristics and mixing requirements to achieve optimal mixing results.

[0020] The end of scraper 13 is inserted into the opening at the end of fixed screw 12, and scraper 13 and fixed screw 12 are fixed by bolts and nuts. The shaft of fixed screw 12 is covered with two sets of nuts and non-slip washers. This structural design not only ensures the secure installation of scraper 13, but also facilitates quick replacement or adjustment when needed.

[0021] The upper end of the movable annular seat 4 is connected to a bogie bearing slide 19, which in turn is connected to an annular slide rail 17. Multiple inner brackets 18 are mounted within the annular slide rail 17, which are secured to the stabilizing bracket 14. This design allows the movable annular seat 4 to rotate freely on the annular slide rail 17, thereby achieving omnidirectional mixing of the mixing drum 2.

[0022] The lower end of the bogie bearing slide 19 is a screw, which is inserted into the opening of the movable annular seat 4 and secured with a nut and anti-slip washers. Multiple bogie bearing slides 19 are distributed in an annular pattern on the annular rail 17. This arrangement ensures uniform distribution and stable rotation of the movable annular seats 4 on the rail, further improving mixing efficiency and quality.

[0023] Ensure that all components are correctly installed and secured in place. Check that the connection between the connector 3 and the stand 1 is provided with a non-slip rubber pad to ensure the stability of the equipment. Confirm that the electric actuator 7, drive motor 15 and other electrical equipment are correctly connected and powered.

[0024] Open the top opening of mixing drum 2. Pour the desired material into mixing drum 2. Start drive motor 15, causing stirring rod 16 to begin rotating. Simultaneously, activate electric push rod 7, driving scraper 13 to reciprocate within mixing drum 2. Stirring rod 16 rotates within mixing drum 2, stirring the material. Driven by electric push rod 7, scraper 13 reciprocates along the inner wall of mixing drum 2, moving the material and ensuring uniform mixing.

[0025] Adjust the extension length of the fixed screw 12 and scraper 13 based on the material characteristics and mixing requirements to achieve the optimal mixing effect. When the scraper 13 is not needed, the fixed screw 12 at the bottom of the scraper 13 is fixed to the U-shaped frame 11 via a nut. At this time, the electric push rod 7 is not activated. Monitor the operating status of the equipment to ensure there are no abnormal sounds or vibrations. When the materials are evenly mixed, turn off the drive motor 15 and the electric push rod 7. Stop the equipment, open the upper opening of the mixing barrel 2, and remove the mixed material.

[0026] Clean the residual material in the mixing barrel 2. Check all parts of the equipment and perform necessary cleaning and maintenance. Ensure that all parts are restored to their original state and ready for the next use; Start the electric push rod 7, move the scraper 13 to the inner wall of the mixing barrel 2 and make contact with it. At this time, start the annular slide 17 and the driving assembly on the steering vehicle bearing slide 19. The steering vehicle bearing slide 19 moves along the annular slide 17, thereby driving the movable annular seat 4 to move. Since the movable annular seat 4 is connected to the mounting frame 6, it drives the scraper 13 to make a circular motion along the inner wall of the mixing barrel 2, thereby realizing the cleaning operation of the inner wall of the mixing barrel 2.

[0027] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
