Description

Technical Field

[0001] This utility model belongs to the field of refractory material production equipment, specifically a refractory material mixer for aluminum alloy furnace groups with a dedicated forklift, unloading switch and guide hopper. Background Technology

[0002] In the construction and maintenance of aluminum alloy smelting furnace groups (including smelting furnaces, holding furnaces, and flow channels), a large amount of refractory materials are needed to bond critical parts such as the furnace mouth, furnace door frame, and furnace bottom. In such scenarios, the traditional method of transferring and pouring materials using a forklift to directly pick up materials from the bottom of the mixing tank is common. However, the forklift is less than 2cm away from the mixing motor and pulleys. Careless handling and excessive shaking can damage the motor and pulleys, posing a serious safety hazard. Furthermore, the discharge port at the bottom of the mixer often lacks effective restraint, resulting in a large discharge range that is difficult to control precisely. This leads to significant material scattering when pouring the mixture into specific locations within the furnace (such as narrow slits or ramps) or into molds. This not only wastes materials, reduces operational efficiency, and increases cleanup costs, but also poses a risk of high-temperature metal splashing near the molten aluminum area.

[0003] Existing solutions are mostly partial repairs, such as: adding a motor protective cover, which leads to poor heat dissipation and increases the motor failure rate by 40%; adding a handheld material receiving trough requires two people to work together, doubling the labor cost.

[0004] CN115007056A provides a mixer for refractory material batching, which achieves continuous feeding through a rotating cylinder and adjustable-angle blades. Although it improves the efficiency of continuous operation, it does not solve the two core pain points of transfer safety and material discharge accuracy in refractory material mixing scenarios.

[0005] Therefore, given the stringent requirements for equipment safety and operational precision in the construction of refractory materials for aluminum alloy furnace groups, there is an urgent need for a mixer with an integrated structural innovation that combines a safe transfer structure with a precise and controllable feeding device. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a special refractory material mixer for aluminum alloy furnace groups with a dedicated forklift, unloading switch and guide hopper. While ensuring efficient and continuous production, it completely eliminates the risk of equipment damage during transportation and achieves precise feeding at set points.

[0007] The technical solution adopted by this utility model to solve the technical problem is:

[0008] This utility model provides a refractory material mixer for aluminum alloy furnace groups, including a mixing tank, support legs, a drive motor located directly below the mixing tank, a belt connection mechanism, and a mixing shaft. The mixing shaft extends into the mixing tank and is equipped with a mixing paddle. A discharge port is provided at the bottom of the mixing tank, and the discharge port is equipped with a discharge switch. The discharge switch includes a rotating shaft vertically arranged on the outer wall of the mixing tank and a rotating plate horizontally arranged at the bottom of the rotating shaft. The rotating plate can block the discharge port. The bottom ends of the three support legs are integrally welded to an integral rectangular base plate. The bottom of the base plate is provided with a fork structure composed of two parallel square tubes, and the length of the square tubes extends to the edge of the base plate.

[0009] Furthermore, a scoop-type guide hopper is fixedly welded below the discharge port, with its inlet located directly below the rotation trajectory of the rotating plate and its width greater than the maximum rotation diameter of the rotating plate.

[0010] Furthermore, the minimum lateral distance between the central channel of the square tube and the housing of the drive motor is ≥15cm.

[0011] Furthermore, the square tube extends 2-10cm beyond the edge of the substrate to form a forklift guide protrusion.

[0012] Furthermore, the substrate is a rolled steel plate with a thickness of ≥10mm, and the top surface of the square tube is fully welded to the bottom surface of the substrate.

[0013] The advantages and positive effects of this utility model are:

[0014] 1. The square tube forklift of this utility model forms a dedicated channel, so that the lateral distance between the fork teeth and the drive motor is ≥15cm, which completely avoids the risk of collision and improves the safety of transportation.

[0015] 2. The horizontal rotating plate of this utility model fits and seals with the surface of the discharge port to avoid material leakage. The feed inlet of the guide hopper is wider than the rotation diameter of the rotating plate to ensure that the material flow is fully received and to ensure accurate and controllable discharge.

[0016] 3. This utility model adopts a rolled steel plate substrate with a thickness of ≥10mm and a square tube full welding process, which improves the deformation resistance by 3 times, reduces the motor damage rate from 1.2 units / month to 0, and provides standing space for operation, thus improving work efficiency.

[0020] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0021] like Figure 1 As shown, a 10mm thick Q235 rolled steel plate is cut into a rectangular base plate 4 of 1.5m × 1.2m. Three Φ80mm round tube legs 3 are vertically welded to the four corners of the base plate to form an integrated support structure. Two 100mm × 50mm square tubes 5 are fully welded along the long side of the bottom of the base plate. The center-to-center distance between the square tubes is 0.8m, and their ends extend outward by 8cm to form a forklift guide protrusion.

[0022] The mixing tank 2 is fixed to the top of the support legs by bolts, and a 5.5kW drive motor 7 is installed at the center of its bottom. The output shaft of the motor is connected to the mixing shaft 1 through a belt connection mechanism 6. The mixing blade is welded onto the mixing shaft.

[0023] The discharge port is located on one side of the bottom of the mixing tank. A Φ25mm rotating shaft 10 is vertically installed on the outside of the mixing tank and is fixed to the tank wall by a flange bearing. A stainless steel rotating plate 9 is horizontally welded to the bottom of the rotating shaft. The size of the rotating plate is precisely matched with the discharge port. Rotating 90° can completely block or open the discharge port.

[0024] Directly below the rotating plate 9, a hopper-type guide hopper 8 is welded, with an inlet width of 450mm, which is greater than the maximum rotating diameter of the rotating plate of 400mm, and the hopper body tilt angle of 55°.

[0025] After assembly, the measured minimum lateral distance between the center channel of the square tube forklift magazine and the housing of the drive motor 7 was 18cm, far exceeding the safety threshold of 15cm. This design ensures that the fork teeth completely avoid the motor's risk zone during forklift operation.

[0026] The method of using this device is as follows:

[0027] During the transfer stage: the forklift inserts the fork teeth along the square tube protrusion, the protrusion guides the fork teeth to be precisely positioned, and the integrated structure of the base plate effectively suppresses shaking;

[0028] Material discharge operation: The operator turns the handle of the rotating shaft 10 with one hand, which drives the horizontal rotating plate 9 to rotate and open the material outlet. The mixture flows out in a direction through the guide hopper 8, and the discharge range is controlled within a diameter of 0.3m.

[0029] Reset and seal: Reverse the rotation shaft to reset the rotating plate horizontally, and the edge of the rotating plate will fit tightly with the discharge port without leakage.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model, and these all fall within the protection scope of the present utility model.
