Description

Technical Field

[0001] This utility model relates to the fields of metallurgy and mining technology, and specifically to a mud ball machine device. Background Technology

[0002] In high-temperature furnace operations (such as blast furnaces, converters, and electric furnaces) in industries like metallurgy and mining, the outlets for molten metal (such as iron and steel) must be promptly plugged after discharge to prevent heat loss or air from entering the furnace and oxidizing the metal. Traditional plugging material is yellow clay (or "firewood"), which must be manually molded into balls and pressed into the discharge outlet. Existing technology has the following problems:

[0003] 1. Defects of traditional manual production

[0004] Low efficiency: Manually beating clay balls is time-consuming, requiring multiple kneading steps for each shaping, which cannot meet the needs of continuous production. Inconsistent specifications: Handmade clay balls vary greatly in size and density, easily leading to poor sealing or excessive compression that damages the furnace opening structure. High labor intensity: Repetitive physical labor in high-temperature environments can easily cause worker fatigue and even occupational injuries.

[0005] 2. Shortcomings of existing mechanization attempts

[0006] Complex structure: Some mechanical briquetting equipment uses multi-link or gear transmission, resulting in high maintenance costs and frequent malfunctions. Poor adaptability: Fixed molds cannot adapt to the discharge port sizes of different furnaces (e.g., diameters ranging from 80 to 150 mm). Insufficient precision: The lack of a guiding mechanism causes deviation in the pressing trajectory, leading to unstable briquetting quality.

[0007] There is an urgent need for an automated mud ball making device with a simple structure, quick mold changing capability, and precise pressing trajectory to solve the above problems. Summary of the Invention

[0008] This invention provides a mud ball making machine device, and more particularly a device for making mud balls for plugging metallurgical furnaces and kilns.

[0009] Therefore, the present invention adopts the following technical solution:

[0010] A mud ball making machine device includes a mud ball making machine device support. An electric hydraulic push rod is fixed on the top crossbeam of the mud ball making machine device support. The piston rod end of the electric hydraulic push rod is provided with a mud ball mold fixing slide plate. A mud ball mold is fixed on the lower surface of the mud ball mold fixing slide plate. The mud ball mold has a cone-shaped molding cavity inside. The inner sides of the two columns of the mud ball making machine device support are symmetrically provided with guide slides that cooperate with the mud ball mold fixing slide plate to guide the vertical movement of the mud ball mold fixing slide plate. A mud ball making platform is provided below the mud ball mold.

[0011] The cone-shaped cavity of the mud ball mold has a diameter of 120mm and a height of 80mm; the support frame of the mud ball machine is welded from channel steel and steel plate and fixed to the ground by bolts with pre-drilled holes.

[0012] The guide slide is made of 40mm×40mm square steel welded to the support frame of the mud ball machine; the mud ball mold fixing slide is made of 30mm steel plate, welded and fixed to the mud ball mold, and reinforced by reinforcing ribs.

[0013] The electro-hydraulic push rod is connected to the fixed base using bolts.

[0014] The electro-hydraulic push rod is detachably connected to the mud ball mold fixing slide plate via connecting bolts.

[0015] The beneficial effects of this utility model are:

[0016] Efficiency Improvement: Forming can be achieved in a single pressing, taking only 1 / 5 of the time compared to manual production; Uniform Specifications: The conical cavity ensures consistent mud ball dimensions; Scalability: Multiple specifications can be produced by changing the mold; Stability: The guide slide and reinforcing rib design ensures no deformation during long-term use. This device can produce plugging mud balls for the melt discharge ports of metallurgical furnaces of different sizes. This invention has a simple structure, strong practicality, and excellent application prospects and value. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figure 1 As shown, a mud ball making machine device includes a mud ball making machine device support 1. An electric hydraulic push rod 2 is fixed on the top crossbeam of the mud ball making machine device support 1. The piston rod end of the electric hydraulic push rod 2 is provided with a mud ball mold fixing slide plate 5. A mud ball mold 7 is fixed on the lower surface of the mud ball mold fixing slide plate 5. The mud ball mold 7 has a cone-shaped molding cavity inside. The inner sides of the two columns of the mud ball making machine device support 1 are symmetrically provided with guide slides 6 that cooperate with the mud ball mold fixing slide plate 5 to guide the mud ball mold fixing slide plate 5 to move vertically. A mud ball making platform 8 is provided below the mud ball mold 7.

[0021] The mud ball machine support frame 1 is welded from channel steel and steel plate. The floor and ground are connected and fixed with pre-drilled bolts to prevent the device from shifting.

[0022] The electric hydraulic push rod 2 is connected to the fixed base 3 using bolts. The mud ball mold fixing slide plate 5 is made of 30mm steel plate. The mud ball mold 7 is connected to the mud ball mold fixing slide plate 5 by welding. Reinforcing ribs are used in some areas for reinforcement. The top of the mud ball mold fixing slide plate 5 is connected to the electric hydraulic push rod 2 using bolts.

[0023] The mud ball mold 7 is made of steel. The bottom of the interior is machined with a cone-shaped cavity with a diameter of 120mm and a height of 80mm. The mud ball mold 7 can be replaced with different molds according to the actual needs on site to meet the needs of making mud balls of various specifications on site.

[0024] The guide slide 6 is made of 40mm×40mm square steel and welded to the mud ball machine device bracket 1. The mud ball mold fixing slide plate 5 slides up and down through the guide slide 6. When the electric hydraulic push rod 2 moves up and down, it drives the mud ball mold 7 to move up and down. When it moves to the mud ball making platform, the mud ball making is completed.

[0025] The mud ball machine support frame primarily supports the mud ball machine and bears the forces exerted during mud ball production. The guide slide ensures that the trajectory of the electric hydraulic push rod remains unchanged during mud ball production. Irregular yellow clay (roasting clay) is molded into uniform, standardized mud balls using mud ball molds, facilitating sealing after the high-temperature molten material is discharged. During mud ball production, workers quantitatively add the pre-mixed roasting clay (usually a mixture of clay, coke powder, and asphalt) to the mud ball production platform. The electric hydraulic push rod then descends, pushing the mud ball mold fixing slide vertically down the guide slide, pressing the mud ball through the conical mold.

[0026] Using a mud ball machine to make mud balls solves the problem of traditional manual production methods. At the same time, it ensures uniform specifications and improves efficiency. Furthermore, by changing the mud ball mold according to the different sizes of the discharge outlets on site, mud balls of different specifications can be produced, which greatly reduces the labor intensity of the job.

[0027] It should be noted that the above are only some embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principle of the present invention, and these improvements and substitutions should also be considered within the protection scope of the present invention.
