Detailed Description of the Embodiment

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] The embodiment of the present application provides a chromium slag pellet drying device, as Figures 1 - 4As shown in the figure, it includes a drying box 1. Inside the drying box 1, there is a bearing platform 2 for bearing chromium slag pellets. The bearing platform 2 is arranged in two rows evenly along the width direction of the drying box 1, and three are arranged evenly along the length direction of the drying box 1 in each row. The layout and quantity of the bearing platform 2 can also be set according to the actual application situation. The bearing platform 2 includes a fixed block 21 fixedly arranged in the drying box 1, and a moving block 22 opposite to and parallel to the fixed block 21 and movably arranged along the width direction of the drying box 1. Placing grooves 23 are opened on the opposite faces of the fixed block 21 and the moving block 22. The bottom surface of the placing groove 23 is arc-shaped. When the bearing platform 2 bears chromium slag pellets, the two placing grooves 23 are respectively attached to the bottom surfaces on both sides of the chromium slag pellets. And when the moving block 22 moves away from the fixed block 21 along the width direction of the drying box 1 to a predetermined length, the distance between the fixed block 21 and the moving block 22 is greater than the diameter of the chromium slag pellets. Above each bearing platform 2, there is a feeding mechanism 3. The feeding mechanism 3 is used to move along the width direction of the drying box 1 with the moving block 22 to complete the feeding of chromium slag pellets. Inside the drying box 1, several drying pipes 4 are arranged evenly along the width direction. Below the drying box 1, there is a discharge box 5.

[0023] During application, the moving block 22 can be driven to move along the width direction of the drying box 1 manually or by setting a linear mechanism. First, drive the moving block 22 to move away from the fixed block 21 along the width direction of the drying box 1. At this time, the feeding mechanism 3 makes preparations for feeding with the movement of the moving block 22, that is, prepares a chromium slag pellet and fixes it at the feeding port of the feeding mechanism 3. Then drive the moving block 22 to move closer to the fixed block 21 along the width direction of the drying box 1. When the distance between the moving block 22 and the fixed block 21 is less than the diameter of the chromium slag pellet, a linkage occurs between the moving block 22 and the feeding mechanism 3. The moving block 22 continues to move closer to the fixed block 21. At the same time, the feeding port of the feeding mechanism 3 opens with the movement of the moving block 22, and the chromium slag pellet falls out from the feeding port and is automatically placed on the bearing platform 2. The placing grooves 23 on the moving block 22 and the fixed block 21 respectively hold the bottoms on both sides of the chromium slag pellet. The drying pipes 4 dry the chromium slag pellet. After the chromium slag pellet is dried, only need to continue to drive the moving block 22 to move away from the fixed block 21 along the length direction of the drying box 1. When the distance between the moving block 22 and the fixed block 21 is greater than the diameter of the chromium slag pellet, the chromium slag pellet will fall from the bearing platform 2 and enter the discharge box 5 for discharging and collecting. While the moving block 22 moves away from the fixed block 21, the feeding process is a repetition of the above process. By moving the moving block 22, the distance between the fixed block 21 and the moving block 22 is controlled to realize the discharging of the chromium slag pellet. At the same time, through the linkage setting between the moving block 22 and the feeding mechanism 3, the process of automatic material preparation and feeding of the feeding mechanism 3 with the movement of the moving block 22 is realized, which greatly optimizes the feeding and discharging process of chromium slag pellets in the drying process and improves the efficiency of chromium slag harmless treatment.

[0024] Specifically, such asFigures 2 - 6 As shown, the feeding mechanism 3 includes a storage frame 31 vertically arranged above the supporting platform 2, and a plurality of chromium slag pellets are vertically installed in the storage frame 31. A group of feeding holes 32 are arranged through the two side frames at the lower part of the storage frame 31, and a mounting groove 33 is opened upward along the vertical direction at the bottom of one side of the storage frame 31. A first rotating shaft 34 is arranged in the mounting groove 33, and the first rotating shaft 34 is parallel to the length direction of the drying box 1. A square hole 351 is arranged in the middle part of the first discharging plate 35, and the first rotating shaft 34 passes through the two side walls of the square hole 351. The torsion spring 34 is sleeved on the first rotating shaft 34 and is located in the square hole 351; each moving block 22 is connected to a second discharging plate 37, one end of the second discharging plate 37 passes through the feeding hole 32, and the other end of the second discharging plate 37 is located outside the storage frame 31, and is connected to an adjustment block 38, and the adjustment block 38 and the other end of the first discharging plate 35 are in the same horizontal plane. When in use, the second discharge plate 37 passes through the feed hole 32 and enters the interior of the storage frame 31. The second discharge plate 37 and the storage frame 31 form a storage space, and the chromium slag pellets are vertically placed in the storage space in sequence; the moving block 22 begins to move away from the fixed block 21 along the width direction of the drying box 1, thereby driving the second discharge plate 37 to withdraw from the feed hole 32, and the chromium slag pellets fall down and are blocked by the first discharge plate 35; the moving block 22 approaches the fixed block 21 along the width direction of the drying box 1, thereby driving the second discharge plate 37 to pass through the feed hole 32 again, enter the interior of the storage frame 31, and place the chromium slag pellets to be stored in the storage space. A chromium slag pellet to be discharged at the bottom is separated from other chromium slag pellets above; the moving block 22 continues to approach the fixed block 21, thereby driving the adjustment block 38 connected to the other end of the second discharge plate 37 to push the other end of the first discharge plate 35, so that the first discharge plate 35 rotates, and the distance between one end of the first discharge plate 35 and the inner wall of the other side of the storage frame 31 is greater than the diameter of the chromium slag pellet. At this time, the chromium slag pellet to be discharged falls out from the lower end of the storage frame 31, and the distance between the fixed block 21 and the moving block 22 is less than the diameter of the chromium slag pellet, thereby holding the fallen chromium slag pellet. Through the arrangement of the second discharge plate 37 and the adjustment block 38 and the structural design of the first discharge plate 35, the feeding mechanism 3 can automatically complete the preparation and feeding of the chromium slag pellets as the moving block 22 moves, thereby improving the automation degree and drying efficiency of the device.

When in use, when discharging and feeding are required, only the handle 16 needs to be pulled to drive the moving plate 12 to move, and then the moving block 22 and the second discharge plate 37 are driven to move, which simplifies the structure and use of the device and improves the drying efficiency.

[0026] Specifically, Figure 4 and Figure 5 As shown, a spring 17 is sleeved on the movable rod 15. When the spring 17 is in a natural state, the second discharge plate 37 passes through the feed hole 32 and is located inside the storage frame 31. The adjustment block 38 abuts against the other end of the first discharge plate 35. When the handle 16 is pulled to make the second discharge plate 37 disengage from the storage frame 31 or the handle 16 is pushed to make the adjustment block 38 push the first discharge plate 35 to rotate, it is resisting the elastic force of the spring 17. The existence of the spring 17 allows the handle 16 to quickly return to its initial position after moving, thereby driving the second discharge plate 37, the movable plate 12, the adjustment block 38, etc. to return quickly, thereby improving the degree of automation of the device.

[0027] Specifically, Figure 3 and Figure 4As shown, an adjustment mechanism 6 is provided below each carrier 2, including three second rotating shafts 61 parallel to each other and arranged along the width direction of the drying box 1, the plane where the three second rotating shafts 61 are located is parallel to the bottom of the drying box 1, one end of the second rotating shaft 61 is matched in a rotating seat 19 provided on the inner wall of one side of the drying box 1, the other end of the second rotating shaft 61 passes through the inner wall of the other side of the drying box 1, and is connected with a worm gear 63, a driving motor 64 is provided on the outer wall of the drying box 1 below the worm gear 63, the driving end of which faces the length direction of the drying box 1, and is connected with a worm 65 meshing with the worm gear 63, an adjusting cam 62 is sleeved on the second rotating shaft 61, and the adjusting cam 62 is located between the fixed block 21 and the movable block 22, when the adjusting cam 62 rotates, the front end of the adjusting cam 62 will contact the chromium slag pellets being dried, and the chromium slag pellets are driven to rotate regularly by relying on the friction generated between the front end of the adjusting cam 62 and the chromium slag pellets, so that the chromium slag pellets are heated evenly, thereby improving the strength of the finished chromium slag pellets.

[0028] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
