Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying equipment with a material turning mechanism. Background Technology

[0002] In the field of material processing, drying is a core process to ensure the accuracy and quality of subsequent material processing. The key is to achieve uniform heating and efficient dehydration of the material. In order to solve the problems of local overheating and uneven heating of materials in traditional static drying methods, drying equipment with a flipping mechanism has been gradually adopted.

[0003] Application No. 202422738052.0 discloses a drying device with a flipping mechanism. This device drives the material-bearing component to move through the flipping mechanism, causing the material to change position within the drying chamber, thereby increasing the frequency of contact between the material and the hot airflow. This optimizes the drying effect to a certain extent and provides a technical direction for batch drying of various materials. However, the existing devices mostly have a fixed 180° unidirectional flipping angle and a single adjustment method. They cannot flexibly adjust the flipping angle and movement trajectory according to the real-time accumulation state of the diamond material due to changes in gravity and humidity during the drying process (such as excessive local stacking or material agglomeration). This results in some material accumulating at the bottom of the bearing component for a long time, making it difficult to fully contact the hot airflow. This directly causes poor drying uniformity and affects the final quality consistency of the material. Secondly, there is a lack of active material dispersing function. The material is prone to agglomeration in a humid state. The existing devices only rely on the gravity generated by the flipping to loosen the material, which cannot effectively disperse the agglomerated material clumps. This results in low internal porosity of the material and high resistance to hot airflow penetration, which not only further aggravates the problem of uneven heating but also significantly reduces the overall drying efficiency. Utility Model Content

[0004] This utility model proposes a drying device with a material turning mechanism to solve the problem that existing drying devices with turning mechanisms have fixed turning angles and single adjustment methods, which cannot adapt to the real-time accumulation state of materials, resulting in poor drying uniformity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device with a material turning mechanism, comprising a drying box, the upper end of which is connected to a box cover by screws, and a perforated material box for carrying the material to be dried is rotatably connected inside the drying box. One end of the perforated material box, located outside the drying box, is provided with a swinging structure for driving the perforated material box to achieve bidirectional tilting and swinging within the drying box to adjust the material stacking posture. The swinging structure includes a first reciprocating screw located outside the drying box. The first reciprocating screw includes a first rod body and a second rod body. A connecting component is provided at the connection between the first rod body and the second rod body for connecting and separating the first rod body and the second rod body. A material-dispersing component is provided inside the perforated material box for breaking up clumps of material within the perforated material box to improve the penetration of hot airflow. A drying component is provided at the upper end of the perforated material box for conveying hot airflow into the perforated material box.

[0006] Preferably, the swing structure further includes a connecting crossbar fixedly connected to the outer wall of the drying chamber, the first reciprocating screw being rotatably connected to the interior of the connecting crossbar, the upper end of the connecting crossbar being provided with an outer plate, a connecting shaft being fixedly connected to one side of the outer plate, and the end of the connecting shaft away from the outer plate penetrating and extending into the interior of the drying chamber and connecting with the hollow material box.

[0007] Preferably, a drive motor is installed on the inner wall of the connecting cross seat, the output end of the drive motor is connected to one end of the first reciprocating lead screw, a moving block is connected to the outside of the first reciprocating lead screw, a movable plate is fixedly connected to the upper end face of the moving block, and multiple toothed blocks are connected to the upper end face of the movable plate and the outer wall of the outer plate.

[0008] Preferably, the connecting assembly includes a slot formed in the inner wall of the first rod, an electromagnet connected inside the slot, a spring sleeved on the outside of the electromagnet, a circular block connected to the free end of the spring, a plug connected to the end of the circular block away from the electromagnet, and a slot for cooperating with the plug formed at the end of the second rod close to the first rod.

[0009] Preferably, a collision sensor is installed on the outer wall of the movable block, and a stop block that works in conjunction with the collision sensor is connected inside the connecting cross seat and at the lower end of the first reciprocating lead screw.

[0010] Preferably, the feeding assembly includes a second reciprocating screw rotatably connected inside the drying chamber, a slider connected to the outside of the second reciprocating screw, an electric telescopic rod connected in a groove reserved on the lower end face of the slider, a connecting frame connected to the free end of the electric telescopic rod, and a feeding strip connected to the lower end face of the connecting frame.

[0011] Preferably, the feeding assembly further includes pulleys rotatably connected inside the connecting cross seat and fixedly connected to one end of the second reciprocating screw. A connecting belt is sleeved on the outside of the two pulleys. A second bevel gear is connected to one end of the pulley inside the connecting cross seat near the first reciprocating screw. A first bevel gear is meshed on one side of the second bevel gear and located on the first reciprocating screw.

[0012] Preferably, the drying assembly includes an air box fixedly connected to the lower end of the box cover by a block. The lower end face of the air box has multiple air outlets equidistantly opened, and the upper end face of the air box is connected to a conveying pipe.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: (1) This application is equipped with a swing structure. During the drying process, the tilt angle and swing direction of the hollow material box can be adjusted by the linkage of the collision sensor and the electromagnetic control component. This not only breaks the limitation of the traditional fixed angle flipping, but also allows the tilting residence time to be flexibly adjusted according to the material drying requirements, so that the materials in different positions can fully contact the hot airflow, fundamentally solving the problem of poor drying uniformity of traditional equipment. Meanwhile, the combination of mechanical structure and electromagnetic control makes the swinging motion stable and controllable without violent impact. While ensuring that the material is fully turned over to improve the heating efficiency, it can also reduce the loss of material caused by collision and improve the drying effect. (2) This application is equipped with a material feeding component. While swinging, the material feeding strip moves laterally in the hollow material box to directly physically disperse the agglomerated material clumps, significantly improving the internal porosity of the material and greatly reducing the penetration resistance of hot airflow. This operation not only further optimizes the drying uniformity and avoids uneven local heating caused by material agglomeration, but also significantly improves the overall drying efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 , Figure 2 and Figure 6 As shown, a drying device with a material turning mechanism includes a drying box 1. The upper end of the drying box 1 is connected to a box cover 2 by screws, and the interior of the drying box 1 is rotatably connected to a hollow material box 3 for carrying the material to be dried. The outer wall of the drying box 1 is provided with ventilation holes 7, and the lower end face of the drying box 1 is connected to a discharge channel 8. The lower end face of the drying box 1 is fixedly connected to a support base 9.

[0019] The upper end of the hollow material box 3 is provided with a drying component 6 for conveying hot air into the hollow material box 3. The drying component 6 includes an air box 63 fixedly connected to the lower end of the box cover 2 by a block. Multiple air outlets 64 are equidistantly opened on the lower end surface of the air box 63, and a conveying pipe 62 is connected to the upper end surface of the air box 63. The inlet end of the conveying pipe 62 passes through and extends to the upper end of the box cover 2, where a heater 61 is installed.

[0020] Specifically, during use, the staff first removes the lid 2 and opens the drying chamber 1, then puts the material to be dried into the perforated material box 3 through the upper opening of the perforated material box 3, and then closes the lid 2; next, the warm air blower 61 is turned on, and the generated warm air is delivered to the air box 63 through the conveying pipe 62, and then blown evenly onto the perforated material box 3 through multiple air outlets 64 on the air box 63, so that the material in different positions in the perforated material box 3 can fully contact the hot airflow, achieve uniform heating and improve drying efficiency; at the same time, the fine impurities mixed in with the material will fall to the bottom of the drying chamber 1 through the holes of the perforated material box 3, and finally be discharged outside the equipment through the discharge channel 8.

[0021] Among them, see Figures 1-4 , Figure 7 and Figure 8 As shown, a swing structure 4 is provided at one end of the hollow material box 3 and outside the drying box 1. The swing structure 4 is used to drive the hollow material box 3 to tilt and swing in both directions inside the drying box 1 to adjust the stacking posture of the material. The swing structure 4 includes a first reciprocating screw 45 located outside the drying box 1. The first reciprocating screw 45 includes a first rod body 451 and a second rod body 452.

[0022] The swing structure 4 also includes a connecting crossbeam 43 fixedly connected to the outer wall of the drying box 1. The first reciprocating screw 45 is rotatably connected to the inside of the connecting crossbeam 43. The upper end of the connecting crossbeam 43 is provided with an outer plate 42. A connecting shaft 41 is fixedly connected to one side of the outer plate 42. The end of the connecting shaft 41 away from the outer plate 42 passes through and extends into the inside of the drying box 1 and connects with the hollow material box 3.

[0023] A drive motor 44 is installed on the inner wall of the connecting cross block 43. The output end of the drive motor 44 is connected to one end of the first reciprocating lead screw 45. A moving block 48 is connected to the outside of the first reciprocating lead screw 45. A movable plate 46 is fixedly connected to the upper end face of the movable block 48. Multiple toothed blocks 47 are connected to the upper end face of the movable plate 46 and the outer wall of the outer plate 42.

[0024] A connecting component 10 is provided at the connection between the first rod 451 and the second rod 452 to realize the connection and separation of the first rod 451 and the second rod 452.

[0025] The connecting assembly 10 includes a slot 101 formed in the inner wall of the first rod 451. An electromagnet 102 is connected inside the slot 101. A spring 106 is sleeved on the outside of the electromagnet 102. A round block 103 is connected to the free end of the spring 106. A plug 104 is connected to the end of the round block 103 away from the electromagnet 102. A slot 105 that mates with the plug 104 is formed at the end of the second rod 452 near the first rod 451.

[0026] A collision sensor 11 is installed on the outer wall of the movable block 48, and a stop block 12 that works in conjunction with the collision sensor 11 is connected to the interior of the cross seat 43 and located at the lower end of the first reciprocating screw 45.

[0027] Through the above technical solution: During the drying process, the first reciprocating screw 45 is driven to rotate by the drive motor 44. The moving block 48 cooperates with the first reciprocating screw 45 to slide stably in the moving groove reserved in the connecting cross seat 43. At the same time, the movable plate 46 moves synchronously with the sliding of the moving block 48. After the collision sensor 11 on the moving block 48 contacts the stop block 12, the electromagnet 102 is energized and generates a suction force on the round block 103. At this time, the elastic force of the spring 106 drives the insert block 104 to move out of the slot 105 and into the empty slot 101, releasing the connection between the first rod body 451 and the second rod body 452. When the tilt angle of the hollow material box 3 reaches the maximum limit, the movement of the movable plate 46 is stopped, and the material is dried at this tilt angle for a period of time. Then the electromagnet 102 is de-energized, its suction force on the round block 103 disappears, and the spring 106 is released. The pre-stored elastic force drives the insert 104 to re-insert into the slot 105, reconnecting the first rod 451 and the second rod 452, causing the movable plate 46 to move in the opposite direction to change the tilt state of the hollow material box 3. During the movement, the movable plate 46 and the multiple toothed blocks 47 on the outer plate 42 mesh with each other, thereby driving the hollow material box 3 to achieve bidirectional tilting and swaying in the drying chamber 1. This structure, through the linkage of the collision sensor 11 and the electromagnetic control component, realizes the control of the tilt angle and swaying direction of the hollow material box 3, solving the limitations of traditional fixed-angle flipping, and can flexibly adjust the tilting dwell time to ensure that the material is fully in contact with the hot airflow to improve the drying uniformity. Moreover, the combination of mechanical and electromagnetic control makes the action stable and controllable without violent impact, ensuring that the material is fully turned over, reducing loss, and taking into account the drying effect, control flexibility and material protection.

[0028] See Figures 3-5 As shown, the hollow material box 3 is equipped with a material-dispersing component 5 inside, which is used to break up the clumps of material inside the hollow material box 3 to improve the penetration of hot airflow.

[0029] The feeding assembly 5 includes a second reciprocating screw 53 rotatably connected inside the drying chamber 1. A slider 55 is connected to the outside of the second reciprocating screw 53. An electric telescopic rod 54 is connected to a groove reserved on the lower end face of the slider 55. A connecting frame 51 is connected to the free end of the electric telescopic rod 54. A feeding strip 52 is connected to the lower end face of the connecting frame 51.

[0030] The feeding assembly 5 also includes pulleys 56 that are rotatably connected inside the connecting cross seat 43 and fixedly connected to one end of the second reciprocating screw 53. A connecting belt 59 is sleeved on the outside of the two pulleys 56. A second bevel gear 58 is connected to one end of the pulley 56 inside the connecting cross seat 43 near the first reciprocating screw 45. A first bevel gear 57 is meshed on one side of the second bevel gear 58 and on the first reciprocating screw 45.

[0031] Through the above technical solution: During the swaying process of the hollow material box 3, the electric telescopic rod 54 extends, driving the material-pushing strip 52 connected to the connecting frame 51 to descend until it contacts the inner wall of the hollow material box 3. Subsequently, the first bevel gear 57 rotates synchronously with the rotation of the first reciprocating screw 45, thereby driving the second bevel gear 58 meshing with it to rotate. Then, through the transmission cooperation of the pulley 56 and the connecting belt 59, the second reciprocating screw 53 is driven to rotate. At this time, the slider 55, in cooperation with the second reciprocating screw 53, moves laterally back and forth in the drying chamber 1, and synchronously drives the material-pushing strip 52 to move laterally in the hollow material box 3. This operation can break up the material and directly physically disperse the agglomerated material clumps, solving the defect of traditional equipment that relies solely on turning and gravity to loosen the material and cannot effectively break up agglomerated materials. The porosity of the material after being broken up is increased, and the resistance to hot airflow penetration is greatly reduced, which not only further optimizes the drying uniformity but also significantly improves the overall drying efficiency.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
