Description

Technical Field

[0001] This utility model belongs to the field of metal chromium ingot processing technology, and more specifically, this utility model relates to a device for crushing metal chromium ingots. Background Technology

[0002] In existing chromium production processes, after the chromium reaction is complete, a cylinder approximately 1 meter in diameter and 40 centimeters thick is formed, depending on the furnace shape used by each manufacturer. The remaining chromium is primarily used as an additive in other alloys, requiring the chromium ingot to be crushed before sale and use.

[0003] Existing crushing methods include using a water-drop hammer, which is raised to a certain height and crushed by gravity. This method is inefficient, labor-intensive, noisy, and causes severe material splashing. Another method uses an excavator breaker hammer to crush the chromium ingots, but this method is also noisy and inefficient. For example, patent application CN201721502937.4 discloses a high-efficiency crushing chamber for scrap steel crushing. This device uses a water-drop hammer for crushing, which generates significant noise during the process, causes severe material splashing, and has low crushing efficiency. Utility Model Content

[0025] like Figure 1 The apparatus shown is for crushing chromium ingots and includes: a base 1, characterized in that it further includes: a gantry support frame 2 disposed on the base 1;

[0026] A conveying assembly 3 is installed on the gantry support frame 2, which uses a stepping method to transport the metal chromium ingot 10 and defines the spatial position of the metal chromium ingot 10;

[0027] A crushing component is installed on the gantry support frame 2 and is spatially perpendicular to the conveying component 3. The crushing component includes: a hydraulic drive component 4 installed on the horizontal beam of the gantry support frame 2, a connecting plate 5 installed at the output end of the hydraulic drive component 4, and a multi-row crushing tooth 6 for crushing the chromium ingot 10 is installed below the connecting plate 5.

[0028] The multiple rows of breaking teeth 6 are arranged in an alternating manner in space.

[0029] Working principle:

[0030] During operation, the conveying assembly 3 is activated, gradually transporting the chromium ingot 10 from its initial position to directly below the crushing assembly. During this transport, the conveying assembly 3 defines the spatial position of the chromium ingot 10, preventing excessive splashing of the crushed ingot. Once the chromium ingot 10 is transported to the designated position, the hydraulic drive component 4 begins operation. The hydraulic drive component 4 is mounted on the horizontal beam of the gantry support frame 2, and it drives the connecting plate 5 up and down through the extension and retraction of its output end. Because multiple rows of crushing teeth 6 are located below the connecting plate 5, as the connecting plate 5 descends, the crushing teeth gradually approach and contact the chromium ingot 10. The multiple rows of crushing teeth 6 are arranged in a staggered pattern, resulting in a larger contact area and more dispersed contact points between the crushing teeth and the chromium ingot 10. When the crushing teeth descend and act on the chromium ingot 10, each row of teeth applies pressure and impact from different angles and positions, increasing the crushing force and uniformity. Compared to traditional single or neatly arranged crushing teeth, the staggered multi-row crushing teeth 6 can crush chromium ingots 10 into the required small pieces more quickly and effectively, greatly improving crushing efficiency and quality. Simultaneously, the conveying assembly 3 uses a stepping transmission method. After one crushing cycle, the conveying assembly 3 restarts, transporting the crushed chromium ingots 10 away and delivering new chromium ingots 10 to the crushing position. The hydraulic drive component 4 then operates again, and this cycle repeats continuously. Furthermore, the staggered arrangement of the crushing teeth prevents repeated crushing of chromium ingots 10 at the same location, thus enabling continuous crushing of chromium ingots 10.

[0031] In the above technical solution, the conveying assembly 3 includes: a conveying platform 31 disposed between the two vertical beams of the gantry support frame 2; a U-shaped pallet 37 disposed on the conveying platform 31 for carrying the chromium ingot 10; a hydraulic component disposed at one end of the conveying platform 31 for pushing the pallet 37; and a pushing component disposed on the hydraulic component for pushing the crushed chromium ingot 10 out of the pallet 37. Using this technical method, when the conveying assembly 3 is started, the conveying platform 31 located between the two vertical beams of the gantry support frame 2 begins operation. The U-shaped pallet 37 carrying the chromium ingot 10 is placed on the conveying platform 31. The cylindrical chromium ingot 10 is placed on the pallet 37. The U-shaped pallet 37 prevents the crushed chromium ingot 10 from splashing out from both sides of the pallet 37. After the chromium ingot 10 is crushed, the pushing component inside the pallet 37 pushes the crushed chromium ingot 10 out of the pallet 37.

[0032] In the above technical solution, the hydraulic component includes: a pair of hydraulic cylinders I 32 arranged on the conveying platform 31 and located on both sides of the pallet 37, an mounting plate 33 is provided on the output shaft of the hydraulic cylinder I 32, and a connecting rod 34 is provided between the mounting plate 33 and the pallet 37;

[0033] The pushing component includes: a hydraulic cylinder II 35 mounted on the mounting plate 33, and a pushing baffle 36 mounted inside the support plate 37. The pushing baffle 36 is connected to the output end of the hydraulic cylinder II 35.

[0034] Hydraulic cylinder I 32 is mounted on the upper surface of the conveying platform 31, and the cross-sectional shape of the pusher baffle 36 matches the cross-sectional shape of the pallet 37. Simultaneously, the length of the connecting plate 5 is consistent with the opening length of the pallet 37. Using this technique, the hydraulic cylinders I 32, paired and located on both sides of the pallet 37 on the conveying platform 31, begin to operate. The hydraulic cylinders I 32, through the extension and retraction of their output shafts, drive the mounting plate 33 to move. Since a connecting rod 34 is provided between the mounting plate 33 and the pallet 37, the movement of the mounting plate 33 pushes the pallet 37 through the connecting rod 34, causing it to move forward step by step along the conveying platform 31. During this process, the two hydraulic cylinders I 32 work together to ensure that the pallet 37 is subjected to uniform force, stably and slowly conveying the chromium ingot 10 from the initial position to directly below the crushing assembly. Once the chromium ingot 10 has been conveyed to the predetermined position, the hydraulic drive component 4 begins to operate. The hydraulic drive component 4 is mounted on the horizontal beam of the gantry support frame 2, and it drives the connecting plate 5 to move up and down through the extension and retraction of its output end. Because multiple rows of crushing teeth 6 are provided below the connecting plate 5, as the connecting plate 5 descends, the crushing teeth gradually approach and contact the chromium ingot 10. The length of the connecting plate 5 is consistent with the opening length of the pallet 37. The crushing teeth on the connecting plate 5 can completely crush the chromium ingot 10 inside the pallet 37. After the crushing operation is completed, the hydraulic cylinder II 35 set on the mounting plate 33 starts to operate. The output end of the hydraulic cylinder II 35 extends. Since the pusher baffle 36 is connected to the output end of the hydraulic cylinder II 35, the pusher baffle 36 will move forward as the output end of the hydraulic cylinder II 35 extends. Furthermore, because the cross-sectional shape of the pusher baffle 36 matches the cross-sectional shape of the pallet 37, the pusher baffle 36 can fit tightly against the inside of the pallet 37, pushing the crushed chromium ingot 10 out of the pallet 37, so that the crushed chromium ingot 10 is transported away. Next, the output shaft of hydraulic cylinder I 32 retracts, driving the pallet 37 back to its starting position via mounting plate 33 and connecting rod 34, ready to receive the new chromium ingot 10 and transport it to the crushing position. At the same time, the hydraulic drive component 4 actuates again to crush the new chromium ingot 10, and this cycle repeats to achieve continuous crushing of the chromium ingot 10.

[0035] In the above technical solution, the gantry support frame 2 is configured as a double gantry support structure. This technical method greatly enhances the stability and load-bearing capacity of the horizontal beam, making the hydraulic drive component 4 operate more smoothly and reliably.

[0036] In the above technical solution, a storage hopper 7 is provided on the base, and an inclined section communicating with the storage hopper 7 is provided at the end of the conveying platform away from the hydraulic cylinder I; wherein, the storage hopper 7 is spatially located below the conveying platform. Using this technical method, after the chromium ingot 10 is crushed, the material inside the pallet is pushed out by the hydraulic cylinder II and the pusher baffle, and enters the storage hopper 7 through the inclined section, completing the crushing and subsequent storage of the material.

[0037] In the above technical solution, a sealing plate 9 is slidably disposed on the side of the connecting plate 5 in the discharge direction. The width of the sealing plate 9 is consistent with the width between the two vertical beams of the gantry support frame 2. In this technical method, the sealing plate 9 is slidably disposed and has multiple waist-shaped grooves 91. The connecting plate 5 is provided with connecting bolts 92 that cooperate with each waist-shaped groove 91. A return spring (not shown in the figure) is provided between the waist-shaped groove 91 and the connecting bolt 92. During the crushing process, when the connecting plate 5 moves downward, the sealing plate 9 first comes into contact with the transport platform. At this time, the sealing plate 9, which is slidably disposed on the side of the connecting plate 5 in the discharge direction, is in a closed state to prevent the metal chromium ingot 10 fragments from splashing during the crushing process. Even when the pallet 37 moves to the position of the sealing plate 9, the sealing plate 9 contacts the upper surface of the pallet 37 and cannot completely seal it. However, the metal chromium ingot 10 will not splash much from the material that has already been crushed at the front end of the pallet 37.

[0038] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
