Technical Field

[0001] The utility model relates to the technical field of wear-resistant ball production, in particular to a semi-finished product drying room for wear-resistant ball production. Background Technique

[0002] During the processing of wear-resistant balls, it is necessary to clean the surface of the wear-resistant balls. After cleaning, the wear-resistant balls need to be dried before entering the subsequent processes. The existing drying methods mostly involve putting a large number of wear-resistant balls into the drying equipment for drying. Due to the excessive concentration of the wear-resistant balls, the moisture on the surface of each wear-resistant ball cannot be effectively dried, reducing the drying quality of the wear-resistant balls. At the same time, the transportation of a large number of wear-resistant balls into the drying equipment also increases the labor intensity and reduces the work efficiency. For example, the patent with the application number 201620574783.9 discloses a steel ball dryer, which solves the problems of large manual labor intensity and low production efficiency, but it has the deficiencies of poor drying quality and low drying uniformity during the drying process of the steel balls.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-4 , an embodiment provided by the present invention: A semi-finished product drying room for wear-resistant ball production, including an outer shell body 16 and a controller 28. Inside the outer shell body 16, a preheating chamber 20, a drying chamber 21, and an equipment chamber 25 are provided from top to bottom through a partition board 29. And a top block 22 is arranged at the center inside the drying chamber 21. On both sides of the top block 22, a movable plate 1 26 and a movable plate 2 27 are respectively installed through a rotating shaft. The other ends of the movable plate 1 26 and the movable plate 2 27 are respectively axially connected to the inside of the drying chamber 21. And an electric heating coil 24 is arranged inside the drying chamber 21 below the movable plate 1 26 and the movable plate 2 27.

[0019] The electric heating coil 24 heats the air inside the drying chamber 21 to dry the wear-resistant balls.

[0020] A push rod 2 is installed at the bottom of the top block 22. The other end of the push rod 2 extends into the equipment chamber 25 and is fixedly connected to a movable seat 5. A roller 7 is installed at the bottom of the movable seat 5. A return spring 9 is installed between the equipment chamber 25 outside the push rod 2 and the movable seat 5. A drive motor 4 is installed inside the equipment chamber 25 below the movable seat 5. A cam 6 that cooperates with the roller 7 is installed on the drive shaft of the drive motor 4.

[0021] The driving motor 4 drives the cam 6 to rotate. The roller 7 at the bottom of the movable seat 5 is always in contact with the outer side of the cam 6 under the action of the return spring 9. When the topmost point of the cam 6 contacts the roller 7, the movable seat 5 drives the push rod 2 to move upward, thereby driving the ends of the first movable plate 26 and the second movable plate 27 connected to the top block 22 to move upward. When the lowest point of the cam 6 contacts the roller 7, the return spring 9 drives the movable seat 5 and the push rod 2 to move downward, thereby driving the ends of the first movable plate 26 and the second movable plate 27 connected to the top block 22 to move downward. In this way, the push rod 2 can be used to drive the first movable plate 26 and the second movable plate 27 to reciprocate up and down inside the drying chamber 21, which can effectively drive the wear-resistant balls on the tops of the first movable plate 26 and the second movable plate 27 to roll and vibrate, preventing the wear-resistant balls from concentrating inside the drying chamber 21, enabling each wear-resistant ball to be in full contact with the hot air, and improving the uniformity and quality of the drying of the wear-resistant balls.

[0022] A hollow cylinder 15 is vertically installed at the center inside the preheating chamber 20. One end of the hollow cylinder 15 extends above the inside of the drying chamber 21, and an exhaust fan 30 is installed at the top end of the hollow cylinder 15. A spiral feed chute 14 is installed inside the preheating chamber 20 on the outer side of the hollow cylinder 15.

[0023] A feed hopper 18 is installed at the top of the outer casing 16. The output end of the feed hopper 18 extends above the spiral feed chute 14, and irregular baffles 11 are alternately arranged inside the spiral feed chute 14. Air holes 17 are provided on the side wall of the hollow cylinder 15 above the spiral feed chute 14, and the air holes 17 are arranged along the shape of the spiral feed chute 14.

[0024] Heat is evenly blown onto the spiral feed chute 14 through the air holes 17 to perform a blowing preheating treatment on the wear-resistant balls rolling inside the spiral feed chute 14. At the same time, when the wear-resistant balls roll downward in the spiral feed chute 14, they hit the irregular baffles 11, causing the wear-resistant balls to vibrate. Meanwhile, the residence time of the wear-resistant balls inside the spiral feed chute 14 is prolonged, further improving the preheating effect and ensuring the subsequent drying effect.

[0025] A funnel-shaped material opening 13 is provided on the partition plate 29 between the preheating chamber 20 and the drying chamber 21 below the output end of the spiral feed chute 14, and heat insulation layers 19 are laid on the inner walls of both the preheating chamber 20 and the drying chamber 21.

[0026] During use, the exhaust fan 30 extracts the heat of the drying chamber 21 and evenly blows it into the spiral feed chute 14 through the air holes 17 to perform a blowing preheating treatment on the wear-resistant balls fed into the spiral feed chute 14. At the same time, the provided irregular baffles 11 can hit the conveyed wear-resistant balls, causing the wear-resistant balls to vibrate while prolonging the residence time of the wear-resistant balls inside the spiral feed chute 14, further improving the preheating effect and ensuring the subsequent drying effect.

[0027] Discharge ports 23 are provided at the positions corresponding to the first movable plate 26 and the second movable plate 27 on both sides of the drying chamber 21. A plug 12 is detachably installed outside the discharge port 23, and a material receiving box body 1 is installed on both sides of the outer casing 16 outside the discharge port 23. The first movable plate 26 and the second movable plate 27 are both of a mesh plate structure.

[0028] The first movable plate 26 and the second movable plate 27 of the mesh plate structure facilitate the transfer of the heat generated by the electric heating coil 24 to the wear-resistant balls.

[0029] Elastic baffles 10 are alternately arranged on both sides of the inner wall of the material receiving box body 1, and the elastic baffles 10 are all inclined downward.

[0030] Prevent the wear-resistant balls from being damaged due to free fall and impact with each other.

[0031] Air outlets 8 are provided on both side walls of the equipment chamber 25. The air outlets 8 are communicated with the material receiving box body 1, and a blower fan 3 is installed inside the equipment chamber 25 outside the air outlets 8.

[0032] The blower fan 3 cools and blows air on the wear-resistant balls dried inside the material receiving box body 1.

[0033] When the embodiment of the present application is in use, pour the wear-resistant balls to be dried into the feed hopper 18. The wear-resistant balls enter the inside of the spiral feed groove 14 of the preheating chamber 20 along the feed hopper 18. The controller 28 controls the electric heating coil 24 to heat up the drying chamber 21. The exhaust fan 30 extracts heat and then evenly blows the heat to the spiral feed groove 14 through the air holes 17 to perform blowing and preheating treatment on the wear-resistant balls rolling inside the spiral feed groove 14. At the same time, when the wear-resistant balls roll downward in the spiral feed groove 14, they hit the irregular stoppers 11, causing the wear-resistant balls to vibrate. At the same time, the residence time of the wear-resistant balls inside the spiral feed groove 14 is extended, further improving the preheating effect and ensuring the subsequent drying effect. The wear-resistant balls pass through the spiral feed groove 14 and enter the inside of the drying chamber 21 through the funnel-shaped material outlet 13, and fall onto the tops of the movable plate one 26 and the movable plate two 27. The driving motor 4 drives the cam 6 to rotate. The rollers 7 at the bottom of the movable seat 5 are always in contact with the outer side of the cam 6 under the action of the return spring 9. When the topmost point of the cam 6 contacts the roller 7, the movable seat 5 drives the push rod 2 to move upward, thereby driving the ends of the movable plate one 26 and the movable plate two 27 connected to the top block 22 to move upward. When the lowest point of the cam 6 contacts the roller 7, the return spring 9 drives the movable seat 5 and the push rod 2 to move downward, thereby driving the ends of the movable plate one 26 and the movable plate two 27 connected to the top block 22 to move downward. In this way, the push rod 2 can be used to drive the movable plate one 26 and the movable plate two 27 to reciprocate up and down inside the drying chamber 21, effectively driving the wear-resistant balls on the tops of the movable plate one 26 and the movable plate two 27 to roll and vibrate, preventing the wear-resistant balls from concentrating inside the drying chamber 21, enabling each wear-resistant ball to be in full contact with the hot air, and improving the uniformity and drying quality of the wear-resistant ball drying. After the wear-resistant balls are dried, open the plug 12, and the wear-resistant balls fall into the receiving box body 1 through the discharge port 23 and are finally discharged through the outlet at the bottom of one side of the receiving box body 1.

[0034] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
