Abstract
Description
Technical Field
[0001] The invention relates to the technical field of metallurgical equipment, in particular to a metal raw material melting equipment. Background Art
[0002] When making metal products (such as aluminum core), the metal raw materials are often melted and then placed in a mold for cooling. Among them, metal raw material melting equipment is needed to melt the metal raw materials. The main structure of the existing metal raw material melting equipment is a furnace body with a heating function. When in use, the metal raw materials are placed in the furnace body and heated until all the raw materials are liquid. When the metal raw material melting equipment is used, since the metal raw materials are completely accumulated in the furnace body for heating, the part that directly contacts the heat transfer medium in the furnace body is relatively small, and the heat absorbed by the metal raw materials located inside is mainly obtained by heat transfer from the metal raw materials outside that directly contact the heat transfer medium in the furnace body. Therefore, the overall melting of the metal raw materials is relatively slow. Summary of the invention
[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a metal raw material melting equipment to solve at least one of the above-mentioned technical problems.
[0004] In order to achieve the above-mentioned object of the invention, the technical solution provided by the present invention is as follows: A metal raw material melting equipment comprises a furnace body and a furnace hood arranged on the top of the furnace body, a material feed port is arranged on the furnace body or the furnace hood, a pipeline is arranged on the top of the furnace hood, a bypass pipe is arranged on the pipeline, one end of the bypass pipe is connected to the pipeline, and the other end passes through the lampshade and is located in the lampshade; a storage chamber is fixed on the bypass pipe near the protective cover, a material inlet is arranged on the top of the storage chamber, a material outlet hole is arranged on the bottom, the material outlet hole is connected to the bypass pipe, and a fan is arranged on the bypass pipe.
[0005] Preferably, a filtering device is provided in the pipeline.
[0006] Preferably, the filtering device is a filter screen, the shape of the filter screen is arc-shaped, and the height in the middle position is higher than the height at both end positions; a central axis is arranged below the filter screen, and the central axis is fixed on the pipeline, corresponding to the position where the bypass pipe is connected to the pipeline; a fan blade is rotatably connected to the central axis, and a scraper is fixed at the edge of the fan blade, and when the fan blade rotates to the position corresponding to the filter screen, the scraper contacts the filter screen.
[0007] Preferably, the filtering device is a filter screen, the filter screen is fixed on the pipeline, and the height of the bottom end is the same as the height of the top end of the bypass pipe.
[0008] Preferably, the end of the bypass pipe not connected to the pipeline is provided with a downwardly facing bell mouth, and the bell mouth is communicated with the interior of the bypass pipe.
[0009] Preferably, a sealing cover is detachably connected to the feed port.
[0010] Preferably, a sealing cover is detachably connected to the material inlet.
[0011] Preferably, a support frame for supporting the bypass pipe is fixed on the furnace body, and the support frame is arranged corresponding to the storage chamber.
[0012] When the metal raw material melting equipment provided by the present invention is used, part of the metal raw material can be placed in the furnace body through the feed port for heating, and then the rest of the metal raw material (metal particles) can be placed in the storage chamber, so that it slides down into the bypass pipe under the action of gravity, and the fan is started during the sliding process of the metal raw material, so that the fan extracts the hot gas rising from the furnace body into the pipeline, and while heating the metal raw material, the metal raw material is blown out of the bypass pipe and finally falls to the bottom of the furnace body. In the process of the metal raw material falling to the bottom of the furnace body, it is fully in contact with the hot air in the furnace body, and is more easily heated and melted. It can be seen from this that in the metal raw material melting equipment of the present application, the metal raw material is not completely accumulated in the furnace body for heating, but partially accumulated in the furnace body for heating, and the rest is preheated through the bypass pipe and then ejected, so that it is heated and melted at the upper part of the furnace body. Compared with the method in which the metal raw material is completely accumulated in the furnace body for heating, the metal raw material melts faster as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0015] Example 1, please refer to Figure 1 The present application provides a metal raw material melting equipment, comprising a furnace body 100 and a furnace cover 200 arranged on the top of the furnace body, the interior of the furnace cover is connected to the interior of the furnace body, a feed port 300 is arranged on the furnace body or the furnace cover, a pipeline 400 is arranged on the top of the furnace cover, the interior of the pipeline is connected to the interior of the furnace cover, a bypass pipe 500 is arranged on the pipeline, one end of the bypass pipe is connected to the pipeline, and the other end passes through the lampshade and is located in the lampshade; a storage chamber 600 is fixed on the bypass pipe near the shield, a material inlet 600-1 is arranged at the top of the storage chamber, and a material outlet hole is arranged at the bottom, the material outlet hole is connected to the bypass pipe, and the material outlet hole is preferably inclined and arranged toward the furnace cover; a fan 700 is arranged on the bypass pipe, generally, the fan can be arranged close to the pipeline, a filter screen 800 is arranged in the pipeline, the filter screen is fixed on the pipeline, and the bottom end height is the same as the top end height of the bypass pipe, wherein the shape of the filter screen can generally be flat.
[0016] When the above-mentioned metal raw material melting equipment is in use, part of the metal raw material can be placed in the furnace body through the feed port for heating, and then the rest of the metal raw material (metal particles) can be placed in the storage chamber, so that it slides down into the bypass pipe under the action of gravity, and the fan is started during the sliding process of the metal raw material, so that the fan extracts the hot gas rising from the furnace body to the pipeline, and while heating the metal raw material, the metal raw material is blown out from the bypass pipe and finally falls to the bottom of the furnace body. In the process of the metal raw material falling to the bottom of the furnace body, it is fully in contact with the hot air in the furnace body, and is more easily heated and melted. It can be seen from this that in the metal raw material melting equipment of the present application, the metal raw material is not completely accumulated in the furnace body for heating, but partially accumulated in the furnace body for heating, and the rest is preheated through the bypass pipe and then ejected, so that it is heated and melted at the upper part of the furnace body. Compared with the method in which the metal raw material is completely accumulated in the furnace body for heating, the metal raw material melts faster as a whole.
[0017] The above-mentioned metal raw material melting equipment is equipped with a bypass pipe in conjunction with a filter screen. When the filter screen is blocked, the rising airflow in the pipeline is reduced. Under the action of the fan, the bypass pipe's attraction for the metal dust attached to the filter screen is relatively enhanced, making it difficult for the metal dust to continue to adhere to the filter screen, thereby effectively preventing the filter screen from being blocked.
[0018] As an embodiment, the end of the bypass pipe not connected to the pipeline is provided with a downward bell mouth, and the bell mouth is connected to the inside of the bypass pipe, so as to facilitate the diffusion of the metal raw material to the outside after being blown out of the bypass pipe.
[0019] In actual production, a sealing cover can also be provided on the feed port, and the sealing cover can be detachably connected to the feed port. The sealing cover can use a rubber plug or other structure, and the sealing cover can be used to seal the feed port after the feeding operation is completed; similarly, the material inlet can also be detachably connected with a sealing cover.
[0020] In order to increase the stability of the storage chamber, a support frame 1020 for supporting the bypass pipe may be fixed to the furnace body, and the support frame is arranged corresponding to the storage chamber.
[0021] Example 2, please refer to Figure 2-Figure 4 The structure of Example 2 is roughly the same as that of Example 1, except that: the filter screen 800 is arranged, wherein the filter screen is in an arc shape, and the height of the middle position is higher than the height of the two end positions; a central axis 900 is arranged below the filter screen, and the central axis is fixed on the pipe, and is arranged corresponding to the position where the bypass pipe is connected to the pipe; a fan blade 1000 is rotatably connected to the central axis, and a scraper 1010 is fixed at the edge of the fan blade, and when the fan blade rotates to the position corresponding to the filter screen, the scraper contacts the filter screen. This structure arranges a bypass pipe to cooperate with the filter screen and the fan blade, and under the action of the fan, the bypass pipe has an attraction effect on the fan blade, especially when the filter screen is blocked, the adsorption effect is relatively enhanced, so that the fan blade drives the scraper to scrape off the metal dust attached to the filter screen, effectively preventing the filter screen from being blocked.
