Description

Technical Field

[0001] This invention relates to the field of carbendazim production technology, and in particular to an integrated dust removal and drying system for carbendazim production. Background Technology

[0002] Carbendazim, also known as cotton wilt fungicide or benzimidazole 44, is a broad-spectrum fungicide effective against diseases caused by fungi (such as deuteromycetes and ascomycetes) in various crops. It can be used for foliar spraying, seed treatment, and soil treatment. While widely used in my country, its residues can cause liver disease and chromosomal aberrations, and it is toxic to mammals.

[0003] In the production of carbendazim, dust removal and drying of materials are crucial steps. Traditional production methods often use separate dust removal and drying equipment to process materials sequentially. This approach not only requires a large floor space, increasing factory space costs, but also easily causes loss and secondary pollution when materials are transferred between different devices, reducing production efficiency and product quality. Furthermore, existing drying equipment lacks uniformity in drying, easily leading to some materials being over-dried while others are under-dried; the filters in dust removal equipment often become clogged after prolonged use, affecting dust removal efficiency and requiring frequent shutdowns for cleaning, further slowing down the production pace, increasing production costs, and making it difficult to meet the demands of efficient and stable carbendazim production. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides an integrated dust removal and drying system for carbendazim production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The dryer shell is equipped with an intermittent feeding mechanism.

[0008] Preferably, the intermittent feeding mechanism is provided in multiple locations, and the air outlets are distributed outside the first vertical pipe at a position below each intermittent feeding mechanism. There are also multiple air outlet pipes, and the positions of the air outlet pipes correspond to the air outlets.

[0009] Preferably, a first bevel gear is fixed to the outside of the first vertical pipe, a rotary motor is fixed to the top of the dryer shell, and a second bevel gear is fixed to the output shaft of the rotary motor, with the first bevel gear meshing with the second bevel gear.

[0010] Preferably, a cleaning brush is fixed to the outside of the first vertical tube, the height of the cleaning brush corresponds to the filter, and the cleaning brush can contact the filter when it rotates with the first vertical tube.

[0011] Preferably, a blocking ring is provided between adjacent intermittent feeding mechanisms. The top of the blocking ring is inclined, and the diameter of the top of the blocking ring is larger than the diameter of the bottom. The upper surface of the blocking ring is provided with a plurality of equally spaced annular protrusions.

[0012] Preferably, the intermittent material feeding mechanism includes a fixed bracket and a lifting drive mechanism. The fixed bracket is provided with multiple material feeding notches, and a fan-shaped sealing plate is provided in the material feeding notch. The fixed bracket and the multiple fan-shaped sealing plates form a boss shape.

[0013] Preferably, the fixed bracket is fixed to the inner wall of the dryer shell, and the lifting drive mechanism drives the fan-shaped sealing plate to rise and fall.

[0014] Preferably, the lifting drive mechanism includes a first lifting ring, a fan-shaped sealing plate is fixed around the first lifting ring by a connecting bracket, and a first limiting rod is fixed on the inner wall of the first lifting ring. A reciprocating guide groove is opened on the outside of the first vertical tube, and one end of the first limiting rod extends into the reciprocating guide groove.

[0015] Preferably, the top end of the first lifting ring is fixed with multiple vertical guide rods, the top ends of the vertical guide rods movably pass through the fixed bracket and extend to the top end of the fixed bracket, and a second lifting ring is fixed between the top ends of the multiple vertical guide rods.

[0016] Preferably, the top of the fixed bracket is fixed with multiple actuators, a second vertical tube is rotatably installed inside the actuators, and a drain cleaner is rotatably installed on one side of the actuators. The tilt angle of the drain cleaner is consistent with that of the fixed bracket. A U-shaped transmission rod is fixed at the top of the second lifting ring corresponding to the position of the second vertical tube. The end of the U-shaped transmission rod away from the second lifting ring extends vertically downward and movably into the second vertical tube. A spiral opening is provided on the second vertical tube. A second limiting rod is fixed to the outside of the U-shaped transmission rod. The second limiting rod extends to the outside of the second vertical tube through the spiral opening. A third bevel gear is fixed on the drain cleaner, and a fourth bevel gear is fixed on the second vertical tube. The third bevel gear meshes with the fourth bevel gear.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Integrated design: The dust removal and drying functions are integrated into one unit. Through the cooperation of components such as the dryer shell, intermittent material feeding mechanism, and first vertical pipe, the equipment footprint is reduced, the loss and pollution caused by the transfer of materials between different equipment are avoided, and the overall production efficiency and product quality are improved.

[0019] 2. High-efficiency drying: Multiple intermittent feeding mechanisms are set up, and the material is blocked and sprinkled intermittently as it falls, which prolongs the residence time of the material in the dryer and increases the contact time with hot air, significantly improving the drying effect and making the material dry more evenly.

[0020] 3. Filter self-cleaning: The cleaning brush fixed to the outside of the first vertical tube can contact the filter when the first vertical tube rotates, regularly cleaning the dust particles covering the filter, keeping the filter unobstructed, reducing the number of downtimes due to filter cleaning, and ensuring production continuity.

[0021] 4. Material slippage optimization: A blocking ring is installed between adjacent intermittent feeding mechanisms. The inclined surface and annular protrusion at the top can slow down the material slippage speed. Combined with the external vibration motor, it further improves the drying effect and promotes more complete heating of the material.

[0022] 5. Improved material dispersion and flowability: The fan-shaped blocking plate of the intermittent feeding mechanism achieves rapid reciprocating lifting and lowering by rotating the first vertical pipe, which disperses the material as it falls and makes it evenly contact the hot air. At the same time, the linkage of components such as the transmission device and the unblocker can stir the material, enhance its flowability, accelerate the falling of the material, and improve the drying efficiency.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] Reference Figure 1-12A dust removal and drying integrated system for carbendazim production includes a dryer shell 1. Multiple feeding ports 101 are located at the top of the dryer shell 1 and are arranged in a ring near the edge of the top. Wet material is added into the dryer shell 1 through the feeding ports 101. Multiple feeding ports 101 improve material distribution uniformity and reduce material accumulation. A discharge port 102 is located at the bottom of the dryer shell 1. A first vertical pipe 3 is rotatably installed inside the dryer shell 1. The top of the first vertical pipe 3 extends to the outside of the dryer shell 1 and is connected to an air inlet pipe 103 via a rotary joint 302. An air outlet pipe 104 is connected to the side wall of the dryer shell 1. A filter 105 is installed inside the dryer shell 1 at the position corresponding to the air outlet pipe 104. An air outlet 303 is provided on the outside of the first vertical pipe 3. An intermittent material dropping mechanism 2 is provided inside the dryer shell 1. The wet material is blocked by the intermittent material dropping mechanism 2 and falls intermittently. Hot air enters the first vertical pipe 3 through the air inlet pipe 103 and is then discharged through the air outlet 303 to dry the intermittently falling material. After being filtered and dusted by the filter 105, the dried product is discharged from the air outlet pipe 104. The dried product falls to the bottom of the dryer shell 1. The finished product can be discharged by opening the ball valve on the discharge port 102.

[0040] Among them, there are multiple intermittent feeding mechanisms 2, and the air outlets 303 are distributed outside the first vertical pipe 3 and located below each intermittent feeding mechanism. There are also multiple air outlet pipes 104, and the positions of the air outlet pipes 104 correspond to the air outlets 303.

[0041] During the material's descent, it is repeatedly blocked by the intermittent feeding mechanism 2 and intermittently sprinkled, which can effectively increase the time the material stays inside the dryer shell 1 during the descent process and increase the contact time between the material and the hot air, thereby improving the drying effect.

[0042] In order to drive the first vertical tube 3 to rotate, a first bevel gear 301 is fixed to the outside of the first vertical tube 3, and a rotary motor 5 is fixed to the top of the dryer shell 1. A second bevel gear 501 is fixed to the output shaft of the rotary motor 5. The first bevel gear 301 and the second bevel gear 501 mesh. When the rotary motor 5 is turned on, it can drive the second bevel gear 501 to rotate, and then drive the first vertical tube 3 to rotate through the meshing of the first bevel gear 301 and the second bevel gear 501.

[0043] A cleaning brush 304 is fixed to the outside of the first vertical tube 3. The height of the cleaning brush 304 corresponds to that of the filter 105. When the cleaning brush 304 rotates with the first vertical tube 3, it can contact the filter 105. When the first vertical tube 3 rotates, it can continuously drive the cleaning brush 304 to rotate as well. The cleaning brush 304 will contact the filter 105 once for each rotation, thereby cleaning the filter 105, removing the dust particles covering the filter 105, and ensuring the unobstructed flow of the filter 105.

[0044] Example 2

[0045] Reference Figure 1-12 The difference between this embodiment and embodiment 1 is that a blocking ring 106 is provided between adjacent intermittent feeding mechanisms. The top of the blocking ring 106 is inclined, and the diameter of the top of the blocking ring 106 is larger than the diameter of the bottom. The upper surface of the blocking ring 106 is provided with multiple equally spaced annular protrusions. The material falling from the intermittent feeding mechanism is blown around by the hot air blown out of the air outlet 303 and falls onto the blocking ring 106, and slowly slides down along the blocking ring 106. The annular protrusions can further play a blocking role, which can further increase the sliding speed and improve the drying effect. A vibration motor can be installed on the outer wall of the dryer shell 1 to drive the whole to vibrate continuously, thereby promoting the downward movement of the material.

[0046] Example 3

[0047] Reference Figure 1-12 The difference between this embodiment and embodiment 2 is that the intermittent feeding mechanism includes a fixed bracket 201 and a lifting drive mechanism. The fixed bracket 201 is provided with multiple feeding notches, and a fan-shaped sealing plate 202 is provided in the feeding notches. The fixed bracket 201 and the multiple fan-shaped sealing plates 202 form a boss shape. The fixed bracket 201 is fixed to the inner wall of the dryer shell 1. The lifting drive mechanism drives the fan-shaped sealing plates 202 to rise and fall.

[0048] As the fan-shaped sealing plate 202 rises and falls rapidly, the gap between the fan-shaped sealing plate 202 and the fixed bracket 201 will continuously increase and decrease, causing the material to fall intermittently through the gap, thus dispersing the material. Because the falling material is more dispersed, it can more evenly contact the hot air to exchange heat and improve the drying effect.

[0049] In order to drive the fan-shaped sealing plate 202 to rise and fall quickly, the lifting drive mechanism includes a first lifting ring 203. The fan-shaped sealing plate 202 is fixed around the first lifting ring 203 by a connecting bracket 205. A first limiting rod 204 is fixed on the inner wall of the first lifting ring 203. A reciprocating guide groove 305 is opened on the outside of the first vertical tube 3. One end of the first limiting rod 204 extends into the reciprocating guide groove 305. Multiple vertical guide rods 206 are fixed at the top of the first lifting ring 203. The top of the vertical guide rods 206 can move through the fixed bracket 201 and extend to the top of the fixed bracket 201. A second lifting ring 207 is fixed between the tops of the multiple vertical guide rods 206.

[0050] As the first vertical tube 3 rotates, the first limiting rod 204 rotates along with the first vertical tube 3. Since the first limiting rod 204 is stuck in the reciprocating guide groove 305, in conjunction with the vertical guiding and limiting function of the vertical guide rod 206, it can quickly drive the fan-shaped blocking plate 202 to continuously reciprocate and rise, thereby achieving the purpose of intermittent material dropping.

[0051] Example 4

[0052] Reference Figure 1-12 The difference between this embodiment and embodiment 3 is that multiple transmission devices 4 are fixed at the top of the fixed bracket 201, a second vertical tube 401 is rotatably installed inside the transmission device 4, and a drain cleaner 402 is rotatably installed on one side of the transmission device 4. The tilt angle of the drain cleaner 402 is the same as that of the fixed bracket 201. A U-shaped transmission rod 208 is fixed at the top of the second lifting ring 207 corresponding to the position of the second vertical tube 401. The end of the U-shaped transmission rod 208 away from the second lifting ring 207 extends vertically downward and movably into the second vertical tube 401. A spiral opening 405 is opened on the second vertical tube 401. A second limiting rod 209 is fixed outside the U-shaped transmission rod 208. The second limiting rod 209 extends to the outside of the second vertical tube 401 through the spiral opening 405. A third bevel gear 403 is fixed on the drain cleaner 402, and a fourth bevel gear 404 is fixed on the second vertical tube 401. The third bevel gear 403 and the fourth bevel gear 404 mesh.

[0053] As the second lifting ring 207 rises and falls continuously, it drives the U-shaped transmission rod 208 to rise and fall continuously, thereby driving the second limiting rod 209 to rise and fall continuously within the second vertical tube 401. Since the second limiting rod 209 is stuck in the spiral opening 405, it drives the second vertical tube 401 to rotate continuously while rising and falling. The rotation direction of the second vertical tube 401 changes with the movement direction of the second limiting rod 209. Since the third bevel gear 403 and the fourth bevel gear 404 mesh, they can drive the drain cleaner 402 to rotate continuously. The drain cleaner 402 can improve the fluidity of the material by stirring, thereby promoting the material to fall from the gap.
