Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ash-adding devices, and in particular to a gravity-type ash-adding device. Background Technology
[0002] A reduction vessel is a key piece of equipment used in metal smelting processes, especially in magnesium smelting. It is the core equipment unit of the Pidgeon process for magnesium smelting. In the production process of the reduction vessel, adding ash is an important step. Adding ash refers to adding specific materials to the reduction vessel. These materials can react with oxides in magnesium ore at high temperatures, thereby extracting metallic magnesium.
[0003] The existing ash-adding device cannot accurately control the amount of ash added each time, and relies entirely on the feeding time to control the amount of ash added. In addition, the presence of the skirt plate makes it impossible to observe the ash-adding situation in real time. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a gravity-type ash-adding device.
[0005] This utility model is achieved using the following technical solution: a self-weight ash-adding device, including a material cylinder, a guide rod is provided inside the material cylinder, a first conical surface is provided in the middle of the inner wall of the material cylinder, a conical block is fixedly connected to the surface of the guide rod, a skirt is fixedly connected to the bottom of the material cylinder, a second conical surface is provided at the bottom of the guide rod, and a reduction tank is provided at the lower end of the material cylinder.
[0006] The above technical solution involves using a clamp-type lifting device on a crane to lift the clamp sleeve, causing the guide rod to move upward. At this point, under the influence of gravity, the first conical surface of the material cylinder completely adheres to the conical block, forming a sealed cavity. Material ash is then added into the cavity. The crane moves to directly above the reduction tank where ash needs to be added, and then the lifting device is lowered, causing the guide rod to move downward. Simultaneously, under the influence of gravity, the skirt of the material cylinder contacts the water jacket inlet of the reduction tank, preventing the material cylinder from descending further. The guide rod is then lowered further, preventing the conical block from contacting the inner wall of the first conical surface, thus allowing the material ash inside the cavity to be added into the reduction tank. Through the conical block on the surface of the guide rod, the addition and stopping of material ash can be achieved solely through the lifting and lowering of the lifting device.
[0007] As a further improvement to the above solution, the dimensions of the first conical surface and the conical block are adapted to each other, and the first conical surface is located at the upper end of the conical block.
[0008] As a further improvement to the above scheme, when the first conical surface and the conical block conical surface are fully fitted, a sealed cavity is formed inside the first conical surface.
[0009] The above technical solution allows for the storage of ash through a sealed cavity.
[0010] As a further improvement to the above solution, the surface of the skirt plate contacts the top of the material cylinder, and the surface of the material cylinder is fixedly connected with a lifting lug.
[0011] The above technical solution, by fitting the skirt plate with the water jacket of the reduction tank to form a sealed space, can effectively improve the dispersion of ash during ash addition.
[0012] As a further improvement to the above solution, two lifting lugs are provided, and the two lifting lugs are arranged circumferentially around the material cylinder.
[0013] The above technical solution allows the material cylinder to be lifted separately using lifting lugs, facilitating subsequent transportation.
[0014] As a further improvement to the above solution, a clamp sleeve is provided at the top of the guide rod, and a connecting bolt is threaded onto the inner wall of the clamp sleeve.
[0015] The above technical solution uses connecting bolts to install and fix the clamp sleeve, which facilitates subsequent disassembly and replacement of different styles of clamp sleeves, making it suitable for different lifting tools and improving the flexibility of use.
[0016] As a further improvement to the above solution, the lower end of the connecting bolt passes through the clamp sleeve and is threadedly connected to the inner wall of the guide rod.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention utilizes a material cylinder, guide rod, first conical surface, and conical block. Specifically, a clamp-type lifting device of a crane lifts the clamp sleeve, causing the guide rod to move upward. Under gravity, the material cylinder causes the first conical surface and the conical block to completely adhere, forming a sealed cavity. Material ash is added into the cavity. The crane moves to directly above the reduction tank where ash needs to be added, and then the lifting device is lowered, causing the guide rod to move downward. Simultaneously, under gravity, the skirt of the material cylinder contacts the water jacket inlet of the reduction tank, preventing the material cylinder from descending further. Then, the guide rod continues to descend, preventing the conical block from contacting the inner wall of the first conical surface, thus allowing the material ash inside the cavity to be added into the reduction tank. Through the conical block on the guide rod surface, the addition and stopping of material ash can be achieved solely through the lifting and lowering of the lifting device.
[0019] This invention, through the design of a skirt plate, a second conical surface, a clamp sleeve, and connecting bolts, specifically forms a sealed space by fitting the skirt plate into the water jacket of the reduction tank. This effectively improves the dispersion of ash during ash addition. The second conical surface at the bottom of the guide rod ensures that the ash is evenly distributed in the gap between the reduction tank and the inner cover plate, rather than on the upper surface of the inner cover plate. This allows the ash to better achieve its heat preservation and sealing function, which is beneficial for improving the temperature and vacuum indicators of the reduction process. By disassembling the connecting bolts, the clamp sleeve can be removed, facilitating the replacement of different styles of clamp sleeves to achieve compatibility with different lifting devices.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0028] Example:
[0029] Please combine Figure 1-5This embodiment of a gravity-type ash-adding device includes a material cylinder 1, a guide rod 2 inside the material cylinder 1, a first conical surface 3 in the middle of the inner wall of the material cylinder 1, a conical block 4 fixedly connected to the surface of the guide rod 2, a skirt plate 5 fixedly connected to the bottom of the material cylinder 1, a second conical surface 6 at the bottom of the guide rod 2, and a reduction tank 7 at the lower end of the material cylinder 1. A clamp sleeve 9 is lifted by a clamp-type lifting device of a crane, causing the guide rod 2 to move upward. At this time, under the action of gravity, the first conical surface 3 and the conical block 4 of the material cylinder 1 completely fit together to form a sealed cavity. Ash is added into the cavity. The crane then travels to the reduction tank where ash needs to be added. 7. Directly above, the lifting device is lowered, causing the guide rod 2 to move downwards. At the same time, under the action of gravity, the position of the skirt plate 5 of the material cylinder 1 contacts the water jacket port of the reduction tank 7. At this time, the material cylinder 1 cannot descend. Then, the guide rod 2 continues to descend, so that the conical block 4 does not contact the inner wall of the first conical surface 3, thereby allowing the material ash inside the cavity to be added into the interior of the reduction tank 7. Through the second conical surface 6 at the bottom of the guide rod 2, the material ash can be evenly scattered into the gap between the reduction tank 7 and the inner cover plate, rather than the upper surface of the inner cover plate. This allows the material ash to better achieve the function of heat preservation and sealing, which is beneficial to improving the temperature and vacuum index of the reduction process.
[0030] The dimensions of the first conical surface 3 and the conical block 4 are matched. The first conical surface 3 is located at the upper end of the conical block 4. Through the conical block 4 on the surface of the guide rod 2, the material can be delivered and stopped by simply lifting and lowering the hoist.
[0031] When the first conical surface 3 and the conical block 4 are fully fitted together, a sealed cavity is formed inside the first conical surface 3.
[0032] The surface of the skirt plate 5 is in contact with the top of the material cylinder 1. The surface of the material cylinder 1 is fixedly connected with the lifting lug 8. After the skirt plate 5 is attached to the water jacket of the reduction tank 7, a sealed space is formed, which can effectively improve the dispersion of ash when adding ash.
[0033] There are two lifting lugs 8, which are arranged in a circle around the material cylinder 1.
[0034] The top of the guide rod 2 is provided with a clamp sleeve 9, and the inner wall of the clamp sleeve 9 is threaded with a connecting bolt 10.
[0035] The lower end of the connecting bolt 10 passes through the clamp sleeve 9 and is threaded to the inner wall of the guide rod 2. By disassembling the connecting bolt 10, the clamp sleeve 9 can be removed, making it easy to replace different styles of clamp sleeve 9 to achieve the function of adapting to different lifting tools.
[0036] The implementation principle of the self-weight ash-adding device in this embodiment is as follows: During use, the clamp sleeve 9 is lifted by the clamp-type lifting device of the crane, causing the guide rod 2 to move upwards. At this time, under the action of gravity, the first conical surface 3 of the material cylinder 1 completely adheres to the conical block 4, forming a sealed cavity. Ash is added into the cavity. The crane moves to directly above the reduction tank 7 where ash needs to be added, and then the lifting device is lowered, causing the guide rod 2 to move downwards. Simultaneously, under the action of gravity, the position of the skirt plate 5 of the material cylinder 1 contacts the water jacket inlet of the reduction tank 7. At this point, the material cylinder 1 cannot descend further. Then, the guide rod 2 continues to descend, preventing the conical block 4 from contacting the inner wall of the first conical surface 3, thereby allowing the ash inside the cavity to be added to the reduction tank 7. Inside, the conical block 4 on the surface of the guide rod 2 allows the feeding and stopping of ash to be achieved solely through the lifting and lowering of the lifting device. After the skirt 5 is fitted with the water jacket of the reduction tank 7, a sealed space is formed, which can effectively improve the dispersion of ash during ash feeding. Through the second conical surface 6 at the bottom of the guide rod 2, the ash can be evenly distributed to the gap between the reduction tank 7 and the inner cover plate, rather than the upper surface of the inner cover plate, so that the ash can better achieve the function of heat preservation and sealing, which is conducive to improving the temperature and vacuum index of the reduction process. By disassembling the connecting bolt 10, the clamp sleeve 9 can be disassembled and removed, making it easy to replace different styles of clamp sleeve 9 to achieve the function of adapting to different lifting devices.
[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
