Description

Technical Field

[0001] This utility model relates to a premixer for casting refractories, and more specifically, to a premixer for casting refractories. Background Technology

[0002] Castable materials are granular and powdery materials made of refractory substances, with the addition of a certain amount of binder and water. They have high fluidity, are suitable for casting, and are monolithic refractory materials that can harden without heating. They are composed of refractory aggregates, powders, binders, additives, water, or other liquid materials. The components of the refractory material need to be mixed in a premixer to form a castable material with high fluidity that is suitable for casting.

[0003] However, existing technologies still have the following problems: Most existing premixers are mixing devices where a mixing shaft drives a mixing rod, and some even have mixing blades on the mixing rod. Because of the relatively fixed arrangement of the mixing rod and blades, these devices can only mix a specific type of castable, lacking flexibility and making it difficult to adapt to mixing multiple types of castables under different needs. Furthermore, the connection and arrangement of existing mixing blades cause stratification when mixing different types of castables, resulting in poor blade coverage. Therefore, we propose a premixer for castables. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a premixer for castables.

[0005] According to a first aspect of the present invention, a premixer for castable refractory is provided, comprising a mixing tank, wherein one end of the upper surface of the mixing tank is connected to an inlet pipe, and an outlet pipe is provided at the bottom of the mixing tank, and further comprising:

[0006] The mixing mechanism includes a stirring blade mechanism and a mixing mechanism. The stirring blade mechanism is provided in multiple sets, and the mixing mechanism is composed of a driving component and a guiding component. The stirring blade mechanism is raised and lowered inside the mixing tank through the guiding component, and the stirring blade mechanism is rotated and installed inside the mixing tank through the driving mechanism.

[0007] A differential component is provided between the driving component and the guiding component, and the driving component is connected to the stirring blade mechanism through the differential component.

[0008] Optionally, the stirring blade mechanism includes a second stirring rod and multiple sets of first stirring rods. The second stirring rod is rotatably mounted inside the mixing tank via a driving component. The multiple sets of first stirring rods are arranged at opposite inclinations, and all multiple sets of first stirring rods are rotatably mounted on the bottom of the second stirring rod.

[0009] Optionally, the driving component includes a stirring motor, one end of the output shaft of the stirring motor is driven to a stirring column through a differential component, the stirring column is rotatably installed inside the mixing tank and is hollow, a fixed column is rotatably installed inside the mixing tank and is located inside the stirring column, and one end of the output shaft of the stirring motor is driven to the fixed column through a differential component.

[0010] Optionally, the differential component includes a gear ring and a second gear. The gear ring is disposed between one end of the output shaft of the stirring motor and the stirring column. The second gear is rotatably mounted on the upper end of the stirring column, and the second gear and the gear ring are connected by meshing transmission through a first gear.

[0011] Optionally, the guide component includes an anti-clogging sleeve, which is slidably fitted onto the outside of the stirring column. The anti-clogging sleeve has multiple sets of mounting holes on its outer side. The anti-clogging sleeve is fixedly fitted onto the outside of the second stirring rod through the mounting holes. The stirring column has a repetitive guide hole on its outer side, and the repetitive guide hole is W-shaped. A guide rod is rotatably mounted on one end of the second stirring rod, and the guide rod is located inside the repetitive guide hole.

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] like Figures 1 to 7 As shown, a premixer for castable refractory includes a mixing tank 4, with an inlet pipe 3 connected to one end of the upper surface of the mixing tank 4, and an outlet pipe 5 provided at the bottom of the mixing tank 4. It also includes:

[0032] The mixing mechanism 1 and the mixing mechanism 6 are provided. The mixing mechanism 1 is provided in multiple sets, and the mixing mechanism 6 is composed of a driving component and a guiding component. The mixing mechanism 1 is raised and lowered inside the mixing tank 4 through the guiding component, and the mixing mechanism 1 is rotated and installed inside the mixing tank 4 through the driving mechanism. A differential component is provided between the driving component and the guiding component, and the driving component is connected to the mixing mechanism 1 through the differential component.

[0033] like Figures 1 to 7 As shown, the stirring blade mechanism 1 can not only rotate inside the mixing tank 4 through the drive mechanism, but also move up and down during the rotation through the guide component. Thus, the stirring blade mechanism 1 can make up for the shortcomings of the dead corners that cannot be stirred by the traditional fixed-position stirring blade. Therefore, the casting premixer can be used to stir different types of casting materials.

[0034] Furthermore, the stirring blade mechanism 1 includes a second stirring rod 102 and multiple sets of first stirring rods 101. The second stirring rod 102 is rotatably installed inside the mixing tank 4 by a driving component. The multiple sets of first stirring rods 101 are arranged at opposite inclinations, and the multiple sets of first stirring rods 101 are rotatably installed at the bottom of the second stirring rod 102.

[0035] like Figures 1 to 7 As shown, by means of a design in which multiple sets of first stirring rods 101 are rotatably mounted on the bottom of the second stirring rod 102, the multiple sets of first stirring rods 101 can assist the second stirring rod 102 in mixing the casting material. Furthermore, the multiple sets of first stirring rods 101 are set in an inclined state, which can further fill the dead corner area between the second stirring rods 102 that are set in a fixed position.

[0036] Secondly, the multiple sets of first stirring rods 101 can also rotate, thus enabling dynamic stirring, further improving the flexibility of the premixer, making the premixer more applicable and faster in stirring.

[0037] Furthermore, the driving component includes a stirring motor 601. One end of the output shaft of the stirring motor 601 is connected to a stirring column 602 via a differential transmission component. The stirring column 602 is rotatably mounted inside the mixing tank 4 and is hollow. A fixed column 603 is rotatably mounted inside the mixing tank 4 and is located inside the stirring column 602. One end of the output shaft of the stirring motor 601 is connected to the fixed column 603 via the differential transmission component. The differential transmission component includes a gear ring 8 and a second gear 10. The gear ring 8 is located between one end of the output shaft of the stirring motor 601 and the stirring column 602. The second gear 10 is rotatably mounted on the upper end of the stirring column 602, and the second gear 10 and the gear ring 8 are connected by the meshing transmission of the first gear 9; the guide component includes an anti-clogging sleeve 2, which is slidably sleeved on the outside of the stirring column 602. Multiple sets of mounting holes are opened on the outside of the anti-clogging sleeve 2. The anti-clogging sleeve 2 is fixedly sleeved on the outside of the second stirring rod 102 through the mounting holes. A repetitive guide hole 604 is opened on the outside of the stirring column 602, and the repetitive guide hole 604 is W-shaped. A guide rod 106 is rotatably mounted on one end of the second stirring rod 102, and the guide rod 106 is located inside the repetitive guide hole 604.

[0038] like Figures 1 to 7 As shown, through the design of the differential component, when the stirring motor 601 drives the stirring column 602 to rotate through the gear ring 8, the gear ring 8 causes the fixed column 603 to rotate through the first gear 9 and the second gear 10. Thus, during the process of the fixed column 603 driving the second stirring rod 102 to rotate, the rotation speeds of the stirring column 602 and the fixed column 603 are inconsistent, allowing the second stirring rod 102 to perform lifting and lowering movements through the repeated guidance of the guide hole 604. Therefore, the situation of dead zones in the mixing tank 4 can be further avoided.

[0039] A sliding groove 7 is provided on the outer side of the fixed column 603, and one end of the guide rod 106 is slidably installed inside the sliding groove 7. The first stirring rod 101 is connected to the repeating guide hole 604 in a transmission manner.

[0040] It should be noted that, since the gear ring 8, the first gear 9 and the second gear 10 form a gear differential mechanism, the rotation speeds of the fixed column 603 and the stirring column 602 are not the same, which allows the second stirring rod 102 to slide vertically up and down inside the sliding groove 7 outside the fixed column 603 along the repeating guide hole 604.

[0041] This allows the second stirring rod 102 to rotate and stir, while also moving up and down, increasing the coverage of the stirring blades and preventing the refractory material from separating.

[0042] Furthermore, multiple sets of toothed grooves 605 are provided on one side of the inner wall of the repetitive guide hole 604. A protective cover 104 is fixedly installed at the bottom of the second stirring rod 102. A rotating rod 103 is rotatably connected to the bottom of the protective cover 104. A repetitive gear 105 is fixedly installed at one end of the rotating rod 103. The repetitive gear 105 is located inside the repetitive guide hole 604 and is rotatably set inside the repetitive guide hole 604 through the toothed grooves 605.

[0043] like Figures 1 to 7 As shown, due to the design of the reciprocating gear 105 rotating inside the reciprocating guide hole 604 via the tooth groove 605, when the second stirring rod 102 moves up and down repeatedly along the direction of the reciprocating guide hole 604 via the guide rod 106, the reciprocating gear 105 will also slide inside the reciprocating guide hole 604 and mesh with the tooth groove 605, thereby rotating. It will drive multiple sets of first stirring rods 101 to rotate through the rotating rod 103, thereby assisting the second stirring rod 102 in stirring and mixing the castable.

[0044] It should be noted that the multiple sets of toothed grooves 605 described above have multiple positions, and there will be gaps between the positions. It should also be noted that the rotation direction of the reciprocating gear 105 is opposite to the transmission direction of the mixing motor 601. Therefore, when the reciprocating gear 105 enters the gap, the multiple sets of first mixing rods 101 can be reset by the resistance of the castable material. Therefore, the reciprocating gear 105 then meshes with the toothed grooves 605 again, and this operation is repeated. This can make the first mixing rods 101 rotate continuously and achieve the effect of assisting the second mixing rod 102 in mixing the castable material.

[0045] It should be noted that two sets of repetitive guide holes 604 are provided above, and the two sets of repetitive guide holes 604 guide in opposite directions. Therefore, the two sets of anti-clogging sleeves 2 can move up and down synchronously to avoid collisions with each other, thereby better preventing the casting material from entering the repetitive guide hole 604.

[0046] Secondly, the anti-clogging sleeve 2 of this utility model can be made of sealing material, which effectively prevents the casting material from entering the repeated guide hole 604.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
