[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1, as Figures 1 to 3 As shown, a mixing device for processing steel-clad bricks includes a mixing drum 1, a mixing motor 2, a mixing shaft 3, a mixing paddle 4, a horizontal plate 5, a lifting block 6, a positioning frame 7, a vertical plate 8, a lifting plate 11, a guide column 12, a reset spring 13, a mixing motor mounting base 14, and a discharge plate 15, among other main components.

[0027] The mixing drum 1 is a vertical cylindrical structure made of rolled and welded steel plate. A wear-resistant ceramic liner can be fixed to the inner wall to extend its service life. A mixing motor 2 is mounted at the top center of the mixing drum 1 via a motor mounting base 14. The mixing motor 2 is preferably a variable frequency reduction motor, allowing for adjustable mixing speed. The output shaft of the mixing motor 2 is connected to a mixing shaft 3 via a coupling, and the mixing shaft 3 extends vertically into the mixing drum 1. Multiple layers of mixing blades 4 are welded to or keyed onto the mixing shaft 3. In this embodiment, three layers are provided, with four blades evenly distributed circumferentially in each layer. The blades are tilted at a certain angle to propel the material axially and radially. A discharge pipe 103 is connected to the bottom of the mixing drum 1, and a pneumatic butterfly valve is installed on the discharge pipe 103 for rapid opening and closing. An outer fixing ring 101 is fixedly fitted onto the upper middle part of the outer wall of the mixing drum 1, and four support legs 102 are welded circumferentially below the outer fixing ring 101.

[0028] The horizontal plate 5 is a long strip of steel plate, which is fixed to the lower part of the stirring shaft 3 by a flange or welding, and is located below the bottommost stirring paddle 4. At each end of the horizontal plate 5, there is a lifting block 6 welded or integrally formed. The part of the lifting block 6 that contacts the bottom end of the vertical plate 8 is processed into an arc surface or an inclined plane to reduce contact impact and achieve smooth lifting.

[0029] Six positioning frames 7 are uniformly welded and fixed along the circumference of the inner wall of the mixing drum 1. The positioning frames 7 are made of angle steel or channel steel, and a vertical rectangular positioning opening 9 is opened on the side facing the mixing shaft 3. The vertical plate 8 is a rectangular steel plate, the width of which matches the positioning opening 9, and can slide up and down along the positioning opening 9. Three inclined lifting plates 11 are welded to the side of the vertical plate 8 facing the mixing shaft 3. The positions of the lifting plates 11 correspond to the gap between two adjacent layers of mixing blades 4 and the area between the bottommost mixing blade 4 and the bottom of the drum. The cross-section of the lifting plate 11 is similar to a spoon or V-shape. Its top surface is concave downward to form a material-collecting area, and its bottom surface (the side facing away from the mixing shaft) convex downward to form a pushing curved surface. This shape is beneficial for carrying more material when rising and reducing the downward drag of material when resetting. A limiting block 10 is welded to the upper part of the side of the vertical plate 8 facing away from the mixing shaft 3. The limiting block 10 is located above the positioning frame 7 and is used to limit the extreme position of the vertical plate 8's downward movement to prevent it from falling out of the positioning opening 9.

[0030] A discharge plate 15 is welded to the bottom of the horizontal plate 5. The discharge plate 15 maintains slight contact or a very small gap with the bottom of the cylinder. During the stirring process, the discharge plate 15 rotates with the horizontal plate 5 and can slightly scrape the material at the bottom of the cylinder. When discharging, the rotating discharge plate 15 can push the material towards the discharge pipe 103 to assist in the discharge and reduce dead corner residue.

[0031] Example 2, as Figure 4 As shown, an elastic reset mechanism is provided between the positioning frame 7 and the vertical plate 8. A guide post limiting sleeve 701 is welded to the side of the positioning frame 7. The guide post limiting sleeve 701 is a block with a central through hole. A guide post fixing seat 801 is welded to the corresponding position of the vertical plate 8. The guide post 12 is a smooth round rod. Its upper end is fixed on the guide post fixing seat 801, and its lower end freely passes through the central hole of the guide post limiting sleeve 701. The reset spring 13 is sleeved on the guide post 12. Its upper end abuts against the lower surface of the guide post fixing seat 801, and its lower end abuts against the upper surface of the guide post limiting sleeve 701, and is in a pre-compressed state. When the vertical plate 8 is lifted upward, the guide post fixing seat 801 moves upward accordingly, further stretching the reset spring 13. When the lifting block 6 rotates and no longer contacts the vertical plate 8, the restoring force of the reset spring 13 pushes the vertical plate 8 to quickly reset downward until the limiting block 10 abuts against the upper surface of the positioning frame 7.

[0032] Working principle: when working, start the stirring motor 2, drive the stirring shaft 3, stirring paddle 4, horizontal plate 5 and lifting block 6 to rotate together, the stirring paddle 4 carries out the conventional shearing, convection mixing to the material in the stirring cylinder 1, and at the same time, the rotating lifting block 6 will be in contact with the bottom end of each vertical plate 8 periodically, because the contact surface is arc or inclined surface, the lifting block 6 will lift the vertical plate 8 together with the lifting plate 11 upwards, the concave top surface of the lifting plate 11 will scoop up the lower layer of material and transport upwards in the lifting process.When the lifting block 6 rotates through the highest point, under the action of the reset spring 13, the vertical plate 8 and the lifting plate 11 quickly descend and reset, the lifted material is dispersed to the middle and upper layers under the action of gravity and surrounding material flow. Such a cycle, each vertical plate 8 and lifting plate 11 are lifted once every revolution of the stirring shaft, realizing the continuous, intermittent self-upward turning function. This forced turning breaks the stratified state of the material due to gravity, so that the dry and wet materials, light and heavy materials added successively can be quickly penetrated and mixed, so that uniform mixing can be achieved in a short time. After mixing is completed, open the valve of the discharge pipe 103, the stirring shaft rotates at low speed, and the discharge plate 15 helps to clear the mixed material.

[0033] The utility model discloses reasonable structure, combine with the stirring mechanism of turning over material mechanism organically, only rely on a stirring motor drive, need not increase additional power, energy -conserving and control simple. Turning over material action and stirring action synchronous coordination, the mixing efficiency and uniformity of remarkable promotion, especially suitable for the mixing process of steel ladle brick and other refractory material this kind of need multi -component, multi -batch feeding, have higher practical value and popularization prospect.

[0034] The above describes, only for the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art in the utility model discloses the technical range of the utility model, according to the utility model technical scheme and the utility model concept of the utility model, equivalent replacement or change, all should be covered in the protection scope of the utility model.
