Description

Technical Field

[0001] The utility model relates to the technical field of roasting kilns, in particular to a roasting kiln with high efficiency heating. Background Art

[0002] Roasted sand is made by heating scrubbing sand to above 870°C and keeping it warm for a certain period of time, so that the silica sand can fully expand and achieve phase change. After the phase change treatment, not only the expansion rate is greatly reduced, but also the bound water, organic pollutants, carbonates, oxides, etc. in the sand particles are largely removed after high-temperature roasting. Therefore, compared with the washed sand, the roasted sand not only has a low acid consumption value, low loss on ignition and gas evolution, and less mud content, but more importantly, a low expansion rate; it can not only reduce the amount of binder added, but also effectively prevent defects such as thermal cracking and sand sticking in castings, and improve the precision of castings; it can produce steel castings, iron castings and non-ferrous alloy castings. When calcining the roasted sand, it is often necessary to use a high-efficiency heating roasting kiln to calcine the roasted sand.

[0003] The prior art, such as the utility model with the publication number CN218646123U, discloses a roasting kiln with high heat exchange efficiency. The patent adopts a roasting assembly, which includes a kiln body, a connecting hopper, an upper hopper, a heating flame nozzle, a heat preservation bin, a lower hopper, a feed folding plate and a guide plate; the upper surface of the kiln body is connected with a connecting hopper. The utility model sets the feed folding plate at less than 58 degrees to prevent the siltation of silica sand caused by the angle of the feed folding plate being too large; the equipment of the utility model solves the problem that the heat exchange time of silica sand is short; the heat exchange time of silica sand is affected by the speed of the rising movement of hot air and the flow time of silica sand from top to bottom, and the flow time of silica sand is determined by the angle of the folding plate. The larger the angle of the folding plate, the slower the flow of silica sand, the longer the flow time, and the longer the heat exchange time. However, if the angle of the folding plate is too large, the flow of silica sand will slow down, and even cause stagnation and siltation of silica sand, and the thickness of the siltation will reversely affect the problem of heat exchange efficiency.

[0004] The inventors have found in their daily work that, in the process of using and feeding the equipment, there is a problem that the material inside the material hopper is accumulated on the surface of the vibrating screen, making it difficult to discharge the material quickly.

When the pull rod moves, it disengages from the inside of the second stabilizing block, and then the material bucket loses its restraint, rotates on the surface of the feed pipe, and disengages from the surface of the feed pipe. By setting a connecting device, the surface of the material bucket and the feed pipe are effectively connected, which plays a role in connecting the material bucket and the feed pipe. After the equipment is used, when the surface of the vibrating screen filters the material, large particles of impurities are easily left on the surface of the vibrating screen, which is difficult to clean, thereby improving the practicality of the equipment.

The side of the feed pipe 3 is fixedly connected with a connecting block 63, and the upper surface of the connecting block 63 is fixedly connected with a sliding rod 64, and the sliding rod 64 is slidably connected to the inner wall of the connecting plate 62. The surface of the sliding rod 64 is sleeved with a first spring 65, and the two ends of the first spring 65 are respectively fixedly connected to the surface of the connecting block 63 and the surface of the connecting plate 62.

[0026] Specifically, a limiting block 67 is fixedly connected to the side of the feed pipe 3 , and a stop block 66 is slidably connected to the inner wall of the limiting block 67 .

[0027] In this embodiment: by setting the limit block 67, the block 66 can be restricted, which reduces the possibility that the block 66 is prone to shaking when the device is in use, making it difficult for the block 66 to move against the connecting plate 62.

[0028] Specifically, a connecting arm 68 is rotatably connected to the surface of the stop block 66 , and one end of the connecting arm 68 away from the stop block 66 is rotatably connected to a turntable 69 . The turntable 69 is provided to facilitate the reciprocating movement of the connecting arm 68 .

[0029] Specifically, a servo motor 610 is fixedly connected to the lower surface of the turntable 69 , and the servo motor 610 is fixedly connected to the surface of the feed pipe 3 . The servo motor 610 is provided to facilitate the rotation of the turntable 69 .

[0030] In this embodiment: a connecting device 7 is provided on the upper surface of the feed pipe 3, and the connecting device 7 includes a material hopper 71 and a first stabilizing block 72.

[0031] In this embodiment: by setting the pull rod 74, the connection between the material hopper 71 and the feed pipe 3 can be restricted, thereby reducing the possibility that the material hopper 71 is easily separated from the surface of the feed pipe 3 when the equipment is in use.

The second spring 77 is provided to facilitate applying a reset elastic force to the limiting rod 76 .

[0034] Working principle: When the silica sand is roasted, the silica sand enters the tank body 1 through the inlet of the tank body 1, and the material continuously flows and moves through the tank body 1. Then the heating pipe 5 of the tank body 1 is connected to the high temperature to heat the inside of the tank body 1. The high-temperature air gradually rises from the bottom of the tank body 1 and contacts with the silica sand entering from the upper part to exchange heat, so that the silica sand undergoes a phase change due to the heat. The silica sand after the phase change flows out from the discharge pipe 4 at the bottom of the tank body 1, and the roasting of the silica sand is completed. When the equipment is in use, the user starts the servo motor 610, and then the servo motor 610 rotates the turntable 69 to rotate, and then the turntable 69 rotates to drive the connecting When the connecting arm 68 moves, the connecting arm 68 drives the stop block 66 to move, and then the stop block 66 drives the connecting plate 62 to move. When the connecting plate 62 moves, the first spring 65 is displaced and deformed to generate elastic force. When the connecting plate 62 moves, the vibrating screen 61 is driven to move. By setting the vibration device 6, the vibrating screen 61 is effectively vibrated, which plays a role in vibrating the material on the surface of the vibrating screen 61, reducing the situation in which the material inside the material bucket 71 accumulates on the surface of the vibrating screen 61 when the equipment is in use, making it difficult to quickly discharge the material, thereby improving the practicability of the equipment.

[0035] After the equipment is in use, the user pulls the pull rod 74 to move, and the movement of the pull rod 74 drives the limiting rod 76 to move, and then the movement of the limiting rod 76 drives the second spring 77 to displace and deform to generate elastic force. When the pull rod 74 moves, it disengages from the interior of the second stabilizing block 73, and then the material hopper 71 loses its restraint, rotates on the surface of the feed pipe 3, and disengages from the surface of the feed pipe 3. By setting the connecting device 7, the material hopper 71 is effectively connected to the surface of the feed pipe 3, which plays a role in connecting the material hopper 71 to the feed pipe 3. After the equipment is used, since the surface of the vibrating screen 61 filters the material, large particles of impurities are easily retained on the surface of the vibrating screen 61, which is difficult to clean, thereby improving the practicality of the equipment.
