Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of mixing equipment, and more specifically, to a high-temperature resistant castable mixing device. Background Technology

[0002] In the field of high-temperature refractory production, the mixing efficiency and discharge convenience of the mixing device directly affect product quality and production continuity. However, traditional mixing devices generally suffer from low mixing efficiency and cumbersome discharge process, making it difficult to meet the refined production needs of high-temperature refractory materials.

[0003] Existing mixing equipment suffers from significant structural defects: First, the agitation structure design is outdated, often employing single-shaft paddle or frame agitation methods. The paddle speed is fixed, and the agitation range is limited to the central area of ​​the unit, making it difficult to fully disperse aggregates and binders in high-temperature castables. Especially when mixing high-density aggregates such as corundum and mullite, single-shaft agitation cannot break up material accumulation dead zones, leading to localized component segregation. For example, coarse and fine aggregates are prone to stratification due to gravity during agitation, affecting the high-temperature mechanical properties of the castable. Second, the discharge mechanism lacks automation. Traditional equipment often uses a bottom-center opening, requiring complete shutdown and manual assistance for unloading, making it difficult to completely remove residual material. When changing to different castable formulations, residual material can easily cause batch contamination, and manual discharge is time-consuming and labor-intensive, severely impacting production efficiency. Third, the sealing structure of the agitator shaft and tank is prone to failure due to high temperatures. Traditional equipment often uses rubber or asbestos seals, which are prone to aging and cracking during prolonged high-temperature agitation operations, leading to material leakage and the infiltration of external impurities, polluting the environment and affecting product purity.

[0004] With the increasing demands for high-temperature refractory performance from industries such as metallurgy and building materials, "efficient mixing, automated discharge, and high-temperature sealing" have become core requirements for production equipment. Traditional equipment, due to its single mixing method and sluggish discharge process, can no longer meet the requirements of continuous production of high-temperature refractory materials. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a high-temperature refractory mixing device. Through the above technical solution, traditional mixing devices generally suffer from low mixing efficiency and cumbersome discharge process, making it difficult to meet the fine production needs of high-temperature refractory materials.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a high-temperature resistant castable mixing apparatus, comprising:

[0007] The base, the bracket, and the high-temperature resistant mixing tank are provided, wherein the bracket is fixed on the base and the high-temperature resistant mixing tank is mounted on the bracket.

[0008] The frame and the oscillating stirring assembly are provided. The frame is rotatably connected to the support via a rotating shaft, and the oscillating stirring assembly is disposed between the frame and the high-temperature mixing tank.

[0009] A feeding / discharging assembly is disposed on the frame and the high-temperature resistant mixing tank;

[0010] The oscillating stirring assembly includes a main motor, which is disposed on the side surface of the support. The output end of the main motor is connected to the rotating shaft of the high-temperature resistant mixing tank. Auxiliary motors are installed on both sides of the high-temperature resistant mixing tank. A stirring frame is disposed at the output end of the auxiliary motor, and the stirring frame is located at both ends inside the high-temperature resistant mixing tank.

[0011] As a further technical solution, the feeding and discharging assembly includes a pair of sliding frames, which are fixed at both ends of the outside of the high-temperature mixing tank. The sliding frames are slidably connected to the frame, and a drive motor is installed at the bottom of the frame.

[0012] As a further technical solution, the output end of the drive motor is provided with a drive gear, and one side of the sliding frame side surface is provided with an external gear, which meshes with the drive gear.

[0013] As a further technical solution, the outer wall of the high-temperature resistant mixing tank is provided with an outer cover, the outer cover is connected to the inside of the high-temperature resistant mixing tank, the surface of the outer cover has an inlet and outlet, and the outer two sides of the outer cover are rotatably connected to a sealing cover by a pin.

[0014] As a further technical solution, the inner surface of the sealing cover is slidably attached to the outer surface of the cover, the sealing cover covers the outside of the inlet and outlet, and a control motor is provided on one side of the outer cover, the output end of the control motor is connected to the sealing cover.

[0015] As a further technical solution, both ends of the high-temperature resistant mixing tank are tapered structures with inclined structural surfaces.

[0016] As a further technical solution, the outer cover surface located at the inlet / outlet portion has a semi-circular structure, and the outer cover matches the arc-shaped surface structure of the outer cover.

[0017] As a further technical solution, the inlet and outlet are offset from the center of the outer cover.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the oscillating mixing assembly is driven by the main motor to oscillate the high-temperature resistant mixing tank back and forth, causing the material to tumble violently due to inertia. The auxiliary motor drives the mixing frame to rotate, shearing and dispersing the material, forming a composite mixing mode of oscillating tumbling and rotational mixing. The main motor can control the oscillation angle and frequency, and the auxiliary motor can adjust the speed of the mixing frame, so that the high-temperature resistant castable is uniformly mixed under the dual action of gravitational potential energy and mechanical force. This solves the problems of low efficiency and dead corners in traditional single-shaft mixing, avoids the separation of aggregate and binder, and improves the mixing quality.

[0020] 2. In this disclosure, the feeding and discharging components drive the mixing tank to rotate via a drive motor, aligning the inlet and outlet in different directions. The motor drives the sealing cover to open and close, achieving automatic feeding and discharging. The sliding frame and sleeve frame's sliding assembly structure ensures smooth rotation of the mixing tank. The fit design between the outer cover and the sealing cover ensures sealing, preventing material leakage and external contamination. This solves the problems of traditional devices relying on manual discharge and cumbersome processes, reduces downtime, improves production efficiency, and adapts to the needs of high-temperature continuous production.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0029] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to 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 disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-3 As shown, it illustrates a high-temperature resistant castable mixing apparatus according to an embodiment of the present disclosure, comprising:

[0033] The system includes a base 1, a support 2, and a high-temperature resistant mixing tank 3. The support 2 is fixed on the base 1, and the high-temperature resistant mixing tank 3 is mounted on the support 2.

[0034] The sleeve 4 and the oscillating stirring assembly 5 are provided. The sleeve 4 is rotatably connected to the support 2 via a rotating shaft, and the oscillating stirring assembly 5 is disposed between the sleeve 4 and the high-temperature mixing tank.

[0035] Feeding and discharging assembly 6, which is disposed on the frame 4 and the high-temperature resistant mixing tank 3;

[0036] The oscillating stirring assembly 5 includes a main motor 5-1, which is disposed on the side surface of the support 2. The output end of the main motor 5-1 is connected to the rotating shaft of the high-temperature resistant mixing tank 3. Auxiliary motors 5-2 are installed on both sides of the high-temperature resistant mixing tank 3. A stirring frame 5-3 is disposed at the output end of the auxiliary motor 5-2. The stirring frame 5-3 is located at both ends inside the high-temperature resistant mixing tank 3.

[0037] In some examples, a oscillating stirring assembly 5 is designed to achieve efficient mixing through repeated left-right oscillation. This assembly uses a main motor 5-1 on the side surface of the support 2 as its power source, and its output end is connected to the rotation shaft of the high-temperature resistant mixing tank 3, driving the mixing tank to oscillate back and forth around the rotation shaft on the support 2. The auxiliary motors 5-2 on both sides of the mixing tank drive the stirring racks 5-3 to rotate at both ends inside the tank. When the mixing tank oscillates, the internal material violently tumbles due to inertia, while the rotation of the stirring racks 5-3 shears and disperses the material, forming a combined mixing mode of oscillating tumbling and rotational stirring.

[0038] The main motor 5-1 can precisely control the swing angle and swing frequency, while the auxiliary motor 5-2 adjusts the speed of the mixing rack 5-3 according to the material characteristics. Under the dual action of the gravitational potential energy generated by the swing and the mechanical force of the mixing rack 5-3, the high-temperature resistant castable achieves uniform distribution of aggregate and binder, avoiding the dead zone problem of traditional static mixing. It is especially suitable for high viscosity and multi-particle castable mixing scenarios.

[0039] like Figures 1-3As shown in the figure, this embodiment proposes that the feeding and discharging assembly 6 includes a pair of sliding frames 6-1. The sliding frames 6-1 are fixed at both ends of the exterior of the high-temperature mixing tank 3. The sliding frames 6-1 are slidably connected to the sleeve 4. A drive motor 6-2 is installed at the bottom of the sleeve 4. A drive gear 6-3 is provided at the output end of the drive motor 6-2. An external gear 6-4 is provided on the side surface of one of the sliding frames 6-1. The external gear 6-4 meshes with the drive gear 6-3. The high-temperature mixing tank 3 An outer cover 6-5 is provided on the outer wall, and the outer cover 6-5 is connected to the interior of the high-temperature resistant mixing tank 3. An inlet and outlet 6-6 are provided on the surface of the outer cover 6-5. A sealing cover 6-7 is rotatably connected to the outer two sides of the outer cover 6-5 by a pin. The inner surface of the sealing cover 6-7 slides and fits against the surface of the outer cover 6-5. The sealing cover 6-7 covers the outside of the inlet and outlet 6-6. A control motor 6-8 is provided on one side of the outer cover 6-5, and the output end of the control motor 6-8 is connected to the sealing cover 6-7.

[0040] In some examples, a feeding / discharging assembly 6 is designed to achieve the feeding and discharging effect through rotational engagement. This assembly is supported by sliding frames 6-1 fixed at both ends of the exterior of the high-temperature resistant mixing tank 3. The sliding frames 6-1 engage with the rolling structure inside the sleeve 4, allowing the mixing tank to rotate with the sleeve 4. The drive motor 6-2 at the bottom of the sleeve 4 meshes with the external gear 6-4 on the side surface of the sliding frame 6-1 via a drive gear 6-3, driving the mixing tank to rotate 180° around its own axis. The outer cover 6-5 on the outer wall of the mixing tank communicates with the inside of the tank. The inlet and outlet 6-6 on the surface can receive and discharge materials as the mixing tank rotates to different orientations. The sealing covers 6-7 on both sides of the outer cover 6-5 are rotatably connected by pins and are driven to open and close by a control motor 6-8: during feeding, the sealing covers 6-7 open, and the inlet and outlet 6-6 align with the feeding device; during discharging, the mixing tank rotates 180° so that the inlet and outlet 6-6 face downwards, and the casting material can flow out by gravity after the sealing covers 6-7 open.

[0041] This component achieves precise rotational positioning of the mixing tank through gear transmission. The sliding fit design of the sealing cover 6-7 and the outer cover 6-5 ensures sealing performance, allowing the high-temperature resistant mixing tank 3 to complete the feeding and discharging processes without disassembly, reducing heat loss and external pollution, and adapting to the continuous production needs of high-temperature operating environments.

[0042] For example, such as Figure 1 As shown, the high-temperature resistant mixing tank 3 has a conical structure with inclined structural surfaces at both ends.

[0043] In some examples, the double-cone structure can concentrate the material at both ends when swinging left and right, which, together with the mixing rack 5-3, improves the mixing efficiency and facilitates the concentrated discharge to the middle, without causing residue.

[0044] For example, such as Figure 1 As shown, the surface of the outer cover 6-5 located in the inlet / outlet 6-6 section is a semi-circular structure, and the outer cover 6-5 matches the arc-shaped surface structure of the outer cover 6-5.

[0045] In some examples, the semi-circular structure allows the outer cover 6-5 to be opened and closed by rotation, and enables rapid material discharge when facing vertically downwards.

[0046] For example, such as Figure 3 As shown, the inlet / outlet 6-6 is offset from the center of the outer cover 6-5.

[0047] In some examples, the outer cover 6-5 can be offset from the center position to allow sufficient room for movement, avoiding excessive rotation angle that could cause it to get stuck and affect material feeding and discharging.

[0048] In actual use: the base 1 is fixed to the ground, the bracket 2 is installed on the base 1, the high-temperature resistant mixing tank 3 is placed on the bracket 2, the sleeve 4 is rotatably connected to the bracket 2 via a rotating shaft, the main motor 5-1 of the oscillating stirring assembly 5 is fixed to the side surface of the bracket 2, and its output end is connected to the rotating shaft of the high-temperature resistant mixing tank 3, the auxiliary motor 5-2 is installed on both sides of the mixing tank, and its output end is connected to the stirring frame 5-3 and extends into both ends of the tank, the sliding frame 6-1 of the inlet / outlet assembly 6 is fixed to both ends of the outside of the mixing tank and slides with the sleeve 4, the drive motor 6-2 is installed at the bottom of the sleeve 4, and the drive gear 6-3 at the output end meshes with the external gear 6-4 on the side surface of the sliding frame 6-1. The outer cover 6-5 is fixed to the outer wall of the mixing tank and communicates with the inside of the tank. The inlet and outlet 6-6 are opened on the surface of the outer cover 6-5. The sealing cover 6-7 is rotatably connected to both sides of the outer cover 6-5 by a pin. The control motor 6-8 is installed on one side of the outer cover 6-5 and connected to the sealing cover 6-7. When in use, the main motor 5-1 drives the mixing tank to swing back and forth, and the auxiliary motor 5-2 drives the stirring frame 5-3 to rotate to achieve material mixing. When feeding or discharging, the drive motor 6-2 drives the mixing tank to rotate through gear transmission, so that the outer cover 6-5 faces down. Then, the control motor 6-8 is started to drive the sealing cover 6-7 to open the inlet and outlet 6-6, and the material is discharged from the inlet and outlet 6-6. When feeding, the tank can be rotated to the top.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
