Description

Technical Field

[0001] The utility model relates to the field of steel shot processing and drying, in particular to steel shot processing and drying equipment. Background Art

[0002] Melt high-quality steel blocks, wool and steel chips, and then use centrifugal discs to high-speed centrifugal forming to throw the molten steel into water, so that the surface temperature of the steel shot drops sharply to form a shot body. This is a quenching. After the quenching, the shot body is dried and reheated and tempered in the furnace to achieve a suitable hardness, and after drying with centrifugal pelletizing, it becomes a semi-finished steel shot.

[0003] In Chinese patent CN205482145U, a steel shot drying system belongs to the field of steel shot production equipment. It is characterized in that it includes a drying furnace with an open top, the furnace body of the drying furnace includes an inner refractory brick layer (2) and an insulation layer (1) outside the refractory brick layer (2), and a heating device is fixed on the inner wall of the refractory brick layer (2). The furnace body is designed as an internal refractory brick layer and an external insulation layer. When drying the steel shot, the high temperature resistance of the furnace body can be improved, and the temperature of the furnace cavity can be guaranteed to be not lost to the greatest extent, thereby improving the utilization rate of heat during the drying process. By setting a nitrogen gas supply unit, the drying furnace is first filled with nitrogen before drying the steel shot. Therefore, when drying the steel shot, the steel shot is dried in an oxygen-free state, thereby avoiding the rust on the surface of the steel shot due to oxidation with oxygen, improving the quality of the steel shot finished product, and saving the subsequent polishing step.

In addition, the steel shots that have been preliminarily processed cannot be properly removed during use. The steel shots will inevitably be worn or even damaged when removed using equipment such as clamps.

The lifting base 203 in the material guide closing plate 201 is cylindrical and will not hinder the rolling out of the steel shots.

[0030] See also Figure 1 , Figure 3 and Figure 4As shown, the visible closed cover assembly 5 includes a sealing top cover 501, a feeding card slot 502, a feeding cover fixing slot 503, a feeding cover fixing block 504, a temporary feeding cover 505, a visual port sliding frame 506, a closing cover sliding slot 507, a closing cover engaging slider 508, and a visual port closing cover 509. A feeding card slot 502 is provided on one side of the sealing top cover 501, and a feeding cover fixing slot 503 is provided inside the feeding card slot 502.

If a small amount of material needs to be added for processing later, the temporary feeding cover 505 can be lifted up through the handle on the temporary feeding cover 505, and the temporary feeding cover 505 is partially removed from the feeding card slot 502 and the feeding cover fixing slot 504 along the four sides. 3 is disconnected, no material is added inwardly, and the steel shot rotates along the inner wall during centrifugal processing.

The seal is restored after the feeding is completed, and the visual port sliding frame 506 on the other side can be used for subsequent observation inwardly. The visual port closing cover 509 is lifted up and moved to the upper position of the closing cover sliding slot 507, and then the closing cover engaging sliders 508 on both sides of the visual port closing cover 509 are slid to one side along the closing cover sliding slot 507 to expose the transparent tempered glass part originally at the bottom of the visual port closing cover 509, so as to effectively observe the internal progress and prevent accidental splashing of steel shots from causing personal injury.

[0032] Working principle: First, open the visible closed cover assembly 5, take out the card blocks along the four sides of the sealing top cover 501 from the card slot, add the material for processing the steel shot into the steel shot drying and processing body 1, and then partially restore the card slot of the sealing top cover 501. If a small amount of material needs to be added for processing later, the temporary feeding cover 505 can be lifted up through the handle on the temporary feeding cover 505, and the temporary feeding cover 505 partly disconnects from the feeding card slot 502 and the feeding cover fixing slot 503 along the four sides, and no material is added inside. When adding materials, the steel shot rotates along the inner wall during centrifugal processing. The feeding slot 502 opened at the innermost position can prevent the steel shot from flying upward along the inner wall. After the feeding is completed, the seal is restored. Later, the visual port sliding frame 506 on the other side can be used to observe inward. The visual port closing cover 509 is lifted up and moved to the upper position of the closing cover sliding slot 507. Then, the closing cover engaging sliders 508 on both sides of the visual port closing cover 509 are slid to one side along the closing cover sliding slot 507 to expose the bottom of the visual port closing cover 509. The transparent tempered glass part can effectively observe the internal progress and prevent accidental splashing of steel balls from causing personal injury. The rotating motor 308 on one side of the steel ball drying processing body 1 starts to operate, and the rotating traction guide rope 306 is engaged with the guide rope transmission block 307 on the top of the rotating motor 308 and the rotating driving groove 305 provided in the rotating connecting ring 304 at the bottom of the centrifugal rotating processing disk 301. When the rotating motor 308 rotates, the guide rope transmission block 307 can drive the rotating connecting ring 304 through the rotating traction guide rope 306, and the rotating connecting ring 304 can rotate. 04 The centrifugal rotating processing disk 301 fixed together rotates, and the centrifugal rotating processing disk 301 is engaged in the steel shot drying processing body 1 through the processing disk engaging groove 302, so that the centrifugal rotating processing disk 301 does not change its position when it rotates. When the centrifugal rotating processing disk 301 rotates, the material inside is centrifugally processed. The circular groove stirring roller 303 arranged inside the centrifugal rotating processing disk 301 adopts a spherical notch. When the material moves to the inside, it rolls upward along the spherical surface and is formed into a spherical shape, thereby improving the quality of the finished product molding;

[0033] Secondly, after the steel shot is processed, the lifting base 203 partially lifts the connecting rod 204 upward, thereby partially lifting the drainage spiral channel 205 and the sealing connection block 206 connected thereto, and the sealing connection block 206 is separated from the connection with the sealing rotating slot 207, and the drainage spiral channel 205 part raised at the bottom is exposed, leading the steel shot to fall into the drainage spiral channel 205, and fall downward along the drainage spiral channel 205 into the material guide closing plate 201. The interior of the material guide closing plate 201 is an inwardly concave arc setting, which can form a slope to effectively buffer the steel shot when it falls in, reducing the impact on the steel shot falling in. The subsequent inclined material guide closing plate 201 causes the internal steel shot to move to the steel shot guide channel 202 on one side. Since the lifting base 203 in the material guide closing plate 201 is cylindrical, it will not hinder the rolling out of the steel shot.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
