Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying equipment for 2-chloronicotinic acid production materials. Background Technology

[0002] Material drying equipment is widely used in industrial production and scientific research, especially for drying dusty materials, where increasingly stringent requirements are placed on the efficiency, quality, and safety of the equipment. This not only affects production progress but also the final quality of the product.

[0003] Currently, most common material drying devices achieve drying by agitation and hot air circulation. However, these devices have several problems in actual operation. On the one hand, relying solely on agitation can easily lead to material accumulation and compaction at the bottom, making it difficult for hot air to penetrate evenly, resulting in uneven drying in certain areas. This affects both drying efficiency and drying quality. On the other hand, to prevent dust from being discharged with the airflow, the device is equipped with filters. However, existing filter structures are complex to replace after clogging, and some designs are prone to accidental contact that could loosen or even disintegrate equipment components, reducing exhaust efficiency and posing safety hazards.

[0004] In response to this technical problem, this application proposes a drying device for 2-chloronicotinic acid production materials. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying device for 2-chloronicotinic acid production materials. In terms of material handling, a fan drives a rotating ring to vibrate the carrying plate, which, in conjunction with the stirring blades, prevents the material from settling and caking, allowing the material to fully contact the hot air and improving drying efficiency and quality. In terms of filter maintenance, the internal structure design avoids accidental disassembly, and the limiting design enables convenient installation and removal of the filter frame, ensuring exhaust efficiency and safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A drying device for 2-chloronicotinic acid production materials includes a hot air blower and a container. A connecting pipe is fixedly connected to the left side of the hot air blower, and a vibration component is provided on the upper side of the connecting pipe. The upper side of the connecting pipe is fixedly connected to the lower side of the container. A support frame is fixedly connected to the lower side of the container. A rotating door is rotatably connected to the left side of the container, and a concave handle is provided on the left side of the rotating door. A motor is fixedly connected to the upper side of the container, and a stirring shaft is fixedly connected to the rotating end of the motor. Stirring blades are fixedly connected to the outer wall of the stirring shaft. A feed inlet is fixedly connected to the upper right side of the container. A fixing component is provided on the upper left side of the container, and a filter frame is fixedly connected to the upper inner arm of the container through the fixing component.

[0008] Furthermore, the fixing component includes a bushing slidably connected to the inside of the upper side of the container, a rotating shaft is provided inside the bushing, a horizontal plate is fixedly connected to the upper side of the rotating shaft, a rotating groove is provided on the outer wall of the rotating shaft, a circular plate is provided inside the rotating groove, and the other end of the circular plate is fixedly connected to the inner wall of the bushing.

[0009] Furthermore, the vibration assembly includes a fan fixedly connected to the upper side of the connecting pipe, a rotating ring fixedly connected to the upper side of the fan, an auxiliary block fixedly connected to the upper side of the rotating ring, a carrying plate slidably connected to the upper side of the auxiliary block, a connecting rod fixedly connected to the lower side of the carrying plate, and a roller rotatably connected to the lower side of the connecting rod.

[0010] Furthermore, a compression spring is provided on the lower side of the bushing, and the outer wall of the compression spring is disposed inside the upper side of the receiver.

[0011] Furthermore, the filter frame has an insertion groove on its upper side, a circular groove inside its upper side, and a sliding groove on its lower side.

[0012] Furthermore, the outer wall of the carrier plate is slidably connected to the inner wall of the container, and an air hole is provided on the lower side of the inner wall of the container.

[0013] Furthermore, the lower side of the roller is disposed on the upper side of the rotating ring, the outer wall of the horizontal plate is rotatably connected to the inside of the circular groove, and a sliding groove is provided on the lower side of the circular groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the device effectively improves drying efficiency and quality through a unique vibration design during material processing. When the material enters the device, the fan rotates, driving the rotating ring. The cooperation between the auxiliary block and the rollers causes the carrying plate to vibrate regularly. This vibration complements the stirring action of the stirring blades. The stirring blades continuously tumble the material, while the vibration prevents the material from settling and caking. The combined effect ensures that the material fully contacts the hot air, accelerating the drying process, ensuring uniform drying, and avoiding problems of insufficient or excessive drying in certain areas.

[0016] 2. In this utility model, the design of the device greatly facilitates the replacement of the filter screen. The filter screen is used to intercept dust carried out by the airflow during the drying process, but it is prone to clogging and needs to be replaced in a timely manner. The device sets the bushing and compression spring inside, which not only avoids disassembly of the device due to accidental contact, but also achieves convenient loading and unloading of the filter screen frame through a clever limiting design. Pressing the hole triggers the compression spring to squeeze the bushing, driving the rotating shaft to rotate, so that the horizontal plate can be rotated 90° and detached from the filter screen frame, making it easy to remove the filter screen frame; conversely, when the horizontal plate is in a horizontal position, the filter screen frame can be smoothly placed in and fixed. The entire replacement process is simple and efficient, effectively ensuring the exhaust efficiency and operational safety of the device. Attached Figure Description

[0024] 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.

[0025] Reference Figure 1 , Figure 2 and Figure 5An embodiment of this utility model provides a drying device for 2-chloronicotinic acid production materials, including a hot air blower 7 and a container 6. A connecting pipe 8 is fixedly connected to the left side of the hot air blower 7. A fan 22 is provided on the upper side of the connecting pipe 8. A rotating ring 10 is fixedly connected to the upper side of the fan 22. An auxiliary block 20 is fixedly connected to the upper side of the rotating ring 10. A carrying plate 13 is slidably connected to the upper side of the auxiliary block 20. A connecting rod is fixedly connected to the lower side of the carrying plate 13. A roller 21 is rotatably connected to the lower side of the connecting rod. The upper side of the connecting pipe 8 is fixedly connected to the lower side of the container 6. A support frame 9 is fixedly connected to the lower side of the container 6. A rotating door 3 is rotatably connected to the left side of the container 6. A concave handle 4 is provided on the left side of the rotating door 3. A motor 1 is fixedly connected to the upper side of the container 6. A stirring shaft 11 is fixedly connected to the rotating end of the motor 1. A stirring blade 12 is fixedly connected to the outer wall of the stirring shaft 11. A feed inlet 5 is fixedly connected to the upper right side of the container 6. A bushing 18 is provided on the upper left side of the container 6. A rotating shaft 23 is provided inside the bushing 18. A horizontal plate 16 is fixedly connected to the upper side of the rotating shaft 23. A rotating groove is provided on the outer wall of the rotating shaft 23. A circular plate 17 is provided inside the rotating groove. The other end of the circular plate 17 is fixedly connected to the inner wall of the bushing 18. A filter screen frame 2 is fixedly connected to the upper inner arm of the container 6 through the horizontal plate 16.

[0026] Specifically, when using the device, the material is put in through the inlet 5 and the motor 1 is started. The internal motor 1 drives the stirring shaft 11 and stirring blades 12 to rotate, thereby stirring the material and making it tumble continuously, thus making it easier to dry. A connecting pipe 8 and a hot air blower 7 are placed at the bottom of the device to provide hot air inside the device. A fan 22 is connected to the outlet of the connecting pipe 8, and the fan 22 is driven by the wind, thereby driving the rotating ring 10 to rotate. During the rotation of the rotating ring 10, the auxiliary block 20 also rotates. When the auxiliary block 20 rotates to the bottom of the roller 21, it will drive the roller 21 to move upward. When the auxiliary block 20 disengages from the bottom of the roller 21, the roller 21 will suddenly drop, thereby causing the carrying plate 13 to vibrate. By repeating this process, the carrying plate 13 can be vibrated frequently, which helps the upper stirring blades 12 to prevent the internal material from settling and caking. During vibration, the airflow moves from the bottom to the top through the air holes 14 on the side of the container 6, blowing away the material dust that is temporarily floating due to vibration. After the inside of the device is dried, the rotating door 3 can be rotated to remove the product from inside. The drying target inside the device is dust, so when the airflow flows from bottom to top, it is easy to carry out dust, so a filter is needed. However, the filter is easily clogged, which slows down the drying efficiency and may even be dangerous, so it needs to be replaced in time. When it is necessary to disassemble, the upper hole can be squeezed. After releasing, the internal compression spring 19 will squeeze the bushing 18 to move upward. Because the inner wall of the bushing 18 has a circular plate 17, and the bushing 18 is slidably connected inside the container 6 and does not rotate, the internal rotating shaft 23 will rotate along the up and down movement of the circular plate 17. When the horizontal plate 16 on the upper side of the rotating shaft 23 rotates 90°, the side groove is enough for the horizontal plate 16 to disengage from the inside of the filter frame 2, so that the filter frame 2 can be removed. In this process, placing the bushing 18 and compression spring 19 inside effectively prevents accidental contact that could lead to the disintegration of the device. Furthermore, the internal rotating groove is designed with limiting mechanisms, ensuring that after the circular plate 17 moves to its lowest point, it only moves upwards along the inclined groove, and when pressed down, it only moves along the vertical groove. With each press, the internal rotating shaft 23 rotates 90°. Therefore, when the horizontal plate 16 is in a horizontal position, the filter frame 2 can be inserted, and the bushing 18 can be compressed, thus securing the device.

[0027] Reference Figure 3 and Figure 4 A compression spring 19 is provided on the lower side of the bushing 18, and the outer wall of the compression spring 19 is located inside the upper side of the container 6. An insertion groove is provided on the upper side of the filter frame 2, and a circular groove 15 is provided inside the upper side of the filter frame 2. A sliding groove is provided below the circular groove 15. The outer wall of the carrying plate 13 is slidably connected to the inner wall of the container 6, and an air hole 14 is provided on the lower side of the inner wall of the container 6. The outer wall of the horizontal plate 16 is rotatably connected to the inside of the circular groove 15, and a sliding groove is provided below the circular groove 15.

[0028] Specifically, during device operation, the hot air blower 7 delivers hot air into the container 6 through the connecting pipe 8. The fan 22 rotates driven by the hot airflow, causing the rotating ring 10 to rotate synchronously. During the rotation of the rotating ring 10, the auxiliary block 20 rotates accordingly. When the auxiliary block 20 rotates to contact the roller 21 and pushes its bottom end, the telescopic rod contracts upward under the thrust, causing the carrying plate 13 to move upward. When the auxiliary block 20 disengages from the bottom end of the roller 21, the telescopic rod quickly resets under the action of a small spring, and the carrying plate 13 suddenly drops, thus achieving high-frequency vibration. This vibration effect, combined with the stirring action of the stirring shaft 11 and the stirring blades 12, keeps the material in a loose state, effectively preventing the material from settling and caking, and improving drying uniformity. Since the material being dried is powdery, the upward airflow easily carries dust out; therefore, the filter frame 2 is crucial. However, filter blockage can affect exhaust efficiency and even pose safety hazards, requiring timely cleaning or replacement. The disassembly and installation of the filter frame 2 are achieved through the linkage structure of the bushing 18 and the compression spring 19: pressing the hole on the upper side of the bushing 18 compresses the spring 19, causing the bushing 18 to move downwards, and the rotating shaft 23 rotates along the rotating groove under the limiting action of the circular plate 17; when the horizontal plate 16 on the rotating shaft 23 rotates 90°, the horizontal plate 16 disengages from the insertion groove, circular groove 15, and sliding groove of the filter frame 2, and the filter frame 2 can be removed. During installation, the horizontal plate 16 is aligned with the insertion groove of the filter frame 2 and inserted, the bushing 18 is released, the compression spring 19 returns to its original position and pushes the bushing 18 upwards, and the rotating shaft 23 drives the horizontal plate 16 back to its original position, thus fixing the filter frame 2. This structure places the bushing 18 and the compression spring 19 inside the container 6, which can prevent accidental contact that could lead to disassembly of the device. At the same time, the limiting design of the rotating groove ensures that the rotating shaft 23 rotates only 90° each time it is pressed, ensuring the stability and reliability of the operation. Pressing down the bottom bushing 18 causes the rotating shaft 23, the horizontal plate 16, and the outer wall rotating groove to rotate under the action of the circular plate 17. The rotating shaft 23 will rotate inside the insertion groove, and the horizontal plate 16 will rotate inside the circular groove 15. After rotating 90°, the horizontal plate 16 can be released from the constraint of the receiver 6 through the sliding groove on the lower side of the circular groove 15.

[0029] Working principle: When cleaning or replacing the filter screen, the operator squeezes the hole on the upper side of the bushing 18, compressing the spring 19 and causing the bushing 18 to move downwards. Due to the limiting fit between the rotating groove on the outer wall of the rotating shaft 23 and the circular plate 17, the rotating shaft 23 will rotate 90° along the rotating groove, causing the horizontal plate 16 to disengage from the circular groove 15 and the slide groove of the filter screen frame 2. At this time, the horizontal plate 16 is unlocked from the insertion slot of the filter screen frame 2, and the operator can directly remove the filter screen frame 2 from the receiver 6. During installation, align the insertion slot of the new filter screen frame 2 with the horizontal plate 16 and insert it. After releasing the bushing 18, the compression spring 19 returns to its original position, pushing the bushing 18 upwards. The rotating shaft 23 drives the horizontal plate 16 back to its original position and locks into the slide groove, completing the fixing of the filter screen frame 2. This structure integrates the operating components, preventing accidental contact that could lead to device disassembly. The limiting design of the rotating groove ensures that the rotating shaft 23 rotates precisely 90° each time it is pressed, guaranteeing operational stability. When the hot air blower 7 delivers hot air to the container 6 through the connecting pipe 8, the airflow drives the fan 22 to rotate, which in turn drives the rotating ring 10 to rotate synchronously. The auxiliary block 20 on the rotating ring 10 rotates together. When the auxiliary block 20 rotates to the bottom of the roller 21, it pushes the roller 21, causing the telescopic rod to retract upwards, compressing the small spring, and moving the carrying plate 13 upwards accordingly. When the auxiliary block 20 disengages from the roller 21, the small spring quickly releases its elastic potential energy, the telescopic rod quickly returns to its original position, and the carrying plate 13 suddenly drops, generating vibration. As the rotating ring 10 continues to rotate, the auxiliary block 20 periodically contacts and disengages from the roller 21, causing the carrying plate 13 to vibrate at high frequency. This vibration, combined with the stirring action of the stirring blade 12, keeps the material in a loose state, effectively preventing the material from settling and caking, and improving the uniformity of drying.
