Abstract
Description
Technical Field
[0001] This invention relates to the field of chemical equipment technology, and more specifically to a transport device for handling chemical materials. Background Technology
[0002] Negative pressure conveying systems are advanced material handling technologies based on the principle of negative pressure. Their operation can be divided into five core stages: negative pressure establishment, material intake, pneumatic conveying, gas-material separation, and gas purification. These stages work together to achieve efficient, clean, and safe material handling. Existing negative pressure conveying systems generally suffer from the serious defect of easy filter clogging. When the system is running, fine powder will adhere tightly to the surface of the filter screen under negative pressure, forming a solid "dust cake". This leads to a sharp increase in system resistance, a decrease in vacuum, and a surge in energy consumption, ultimately resulting in a significant reduction in conveying efficiency or even interruption. Traditional automatic dust removal methods rely on an external compressed air source, which not only increases additional energy consumption and equipment costs, but also makes the dust removal effect susceptible to the quality of the air source. In addition, existing systems generally face reliability issues in the feeding process when handling chemical materials that are prone to adhesion, moisture absorption, or high viscosity. Materials are prone to "bridging," "clumping," and sticking to the walls in the feeding tank, resulting in poor feeding, supply interruption, or unevenness. It is difficult to effectively break up internal clumps and peel off materials adhering to the tank walls, and the material flowability cannot be fundamentally improved, leading to pipeline blockage or system evacuation. Summary of the Invention
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a transportation device for handling chemical materials to solve the problems existing in the background art.
[0004] The present invention provides the following technical solution: a transport device for handling chemical materials, comprising a filtration mechanism, a self-stirring tank mechanism, a pipeline, a negative pressure adsorption tank, a receiving tank, and a suction valve. A pipeline is fixedly connected to one side of the filtration mechanism. The self-stirring tank mechanism is fixedly connected inside the pipeline near the filtration mechanism. A rebound cleaning mechanism is fixedly connected to the outer end of the self-stirring tank mechanism near the filtration mechanism. A negative pressure adsorption tank is fixedly connected to the other side of the pipeline. A suction valve is fixedly connected to the other side of the negative pressure adsorption tank. A receiving tank is provided at the bottom of the negative pressure adsorption tank. Furthermore, the material is first fed into the self-stirring tank mechanism, and the suction valve is activated to start the suction operation inside the pipeline. The material is transported inside the pipeline and finally reaches the negative pressure adsorption tank for collection. After the overall transportation is completed, the suction valve is closed, the opening at the bottom of the negative pressure adsorption tank is opened, and the material is transferred to the receiving tank to complete the entire transportation process.
[0005] Furthermore, the self-stirring tank mechanism includes a lower connecting pipe fixedly connected to the pipeline, a tank shell fixedly connected to the top of the lower connecting pipe, a rotating shaft rotatably connected to the inside of the tank shell near the lower connecting pipe, and a special-shaped gear fixedly connected to the rotating shaft.
[0006] Furthermore, a fixed frame is fixedly connected to the inside of the tank shell near the top of the rotating shaft. A central shaft is slidably connected to the center of the fixed frame. A gear plate is provided at the bottom of the central shaft and the top of the shaped gear. A spring is fixedly connected to the top of the gear plate and the bottom of the fixed frame. A connecting rod is fixedly connected to the outer circumferential side of the central shaft. A stirring arm is fixedly connected to the other side of the connecting rod.
[0007] Furthermore, the irregularly shaped gear is eccentrically positioned, and the irregularly shaped gear meshes with the gear plate through a toothed joint.
[0008] Furthermore, one end of the rotating shaft is connected to a motor. When the motor is turned on, the rotating shaft rotates, which in turn drives the irregularly shaped gear fixedly connected to it to rotate. Due to the eccentric connection of the irregularly shaped gear on the rotating shaft, it will cause vertical displacement of the gear plate in the vertical direction during rotation. At the same time, under the mutual meshing of the gear teeth, the gear plate will also rotate. The vertical displacement of the gear plate will be transmitted to the third spring, causing the third spring to be stretched and compressed to a certain extent for buffering. The rotation of the gear plate will continue to be transmitted to the central shaft fixedly connected to it. The stirring arm connected to the central shaft through the connecting rod will also rotate continuously with it. This provides continuous stirring during the process of material entering the tank and during transportation. It is suitable for materials with a certain degree of adhesion, ensuring the continuity and integrity of the material transportation process.
[0009] Furthermore, the filtration mechanism includes a pipe shell fixedly connected to the other end of the pipe, and a screen is provided on the inner side of the other end of the pipe shell. The rebound cleaning mechanism includes a limiting rod fixedly connected to the outer surface of the tank shell near the screen, and an outer cylinder is fixedly connected to the bottom of the limiting rod.
[0010] Furthermore, a top plate is fixedly connected to the other side of the limiting rod, and a slender rod is fixedly connected to the bottom of the top plate. A rotating plate is rotatably connected to the other end of the rotating shaft via a short shaft. A small base is rotatably connected to the top of the rotating plate, and a first layer plate is fixedly connected to the bottom of the small base. A spring is provided on the bottom of the first layer plate near the outside of the slender rod. A second layer plate is fixedly connected to the bottom of the spring. A slender rod is slidably connected to the bottom of the first layer plate through the second layer plate. A spring is provided on the bottom of the second layer plate near the outside of the slender rod. A bottom plate is fixedly connected to the end of the slender rod that passes through the first and second layers plates, near the spring. A round rod is provided on the bottom of the second layer plate through the bottom plate, and a rubber block is fixedly connected to the bottom of the round rod. Furthermore, a motor is connected to one end of the rotating shaft. When the motor starts, the rotation of the rotating shaft is transmitted to the two connected rotating plates through a short rod. The rotation of the rotating plates and the small base together converts the rotation of the rotating shaft into a reciprocating motion in the vertical direction of the first plate and the structure below it. A slender rod slides from the top plate through the first and second plates and is finally fixedly connected to the bottom plate. After the rotating plate transmits displacement downward, the first plate will compress spring one, and the spring will continue to compress the second plate. At the same time, the second plate will also compress spring two. The second plate will drive the round rod and the rubber block at its bottom downward to complete the action of striking the tube shell. After falling, the rubber block moves upward under the traction of the rotating plate and the round rod. At the same time, spring two and spring one also exert force synchronously to release the force that was just compressed, helping the second plate and the round rod to move upward. Spring two and spring one play an auxiliary role in the entire process to complete the striking action and buffer the impact. In addition, due to the inertia of the spring, it can help the first plate to complete the reciprocating motion better, repeatedly striking the tube shell to clean the dust cake on one side of the screen.
[0011] The technical effects and advantages of this invention are as follows: This invention features a rebound cleaning mechanism that utilizes the rotational power of the main conveyor motor. Through the coordinated linkage of a rotating plate, multi-layer plates, and spring assembly, continuous rotation is transformed into reciprocating impact motion. Springs one and two not only transmit motion and provide cushioning, but their energy storage and release characteristics amplify the impact force, enabling the rubber block to effectively vibrate the filter housing. This effectively cracks and peels off stubborn dust cakes adhering to the screen surface, changing the traditional passive cleaning method that relies on external air sources or manual intervention. It achieves uninterrupted automatic cleaning during the conveying process, greatly reducing filter resistance, maintaining a stable vacuum level and conveying efficiency, while eliminating additional energy consumption and equipment costs, and improving the system's continuous operation capability and reliability.
[0012] This invention features a self-stirring tank mechanism. Through the meshing transmission of a shaped gear and a gear plate, the single rotary input of the motor is combined into a stirring arm that simultaneously performs rotation and axial movement. This biomimetic stirring action effectively breaks up internal agglomerates of materials and peels off materials adhering to the tank wall, greatly improving the flowability of the materials and ensuring continuous and uniform feeding. Compared with traditional simple rotating agitators, the stirring effect is stronger and has no dead angles. It is particularly suitable for tricky materials that are prone to absorbing moisture and clumping. It eliminates the risk of pipeline blockage caused by interruption or uneven feeding from the source of the conveying process, ensuring the smoothness, stability and efficiency of the entire negative pressure adsorption conveying process.

The rebound cleaning mechanism 2 is fixedly connected to the outside of the self-stirring tank mechanism 3 near the filter mechanism 1. The negative pressure adsorption tank 6 is fixedly connected to the other side of the pipe 4. The suction valve 7 is fixedly connected to the other side of the negative pressure adsorption tank 6. The receiving tank 5 is provided at the bottom of the negative pressure adsorption tank 6. Reference Figure 1 First, the material is put into the self-stirring tank mechanism 3, and the suction valve 7 is started to start the suction operation inside the pipe 4. The material is transported inside the pipe 4 and finally reaches the negative pressure adsorption tank 6 for collection. After the overall transportation is completed, the suction valve 7 is closed, the opening at the bottom of the negative pressure adsorption tank 6 is opened, and the material is transferred to the receiving tank 5 to complete the entire transportation.
[0023] Reference Figure 2 The self-stirring tank mechanism 3 includes a lower pipe 304 fixedly connected to the pipe 4. A tank shell 301 is fixedly connected to the top of the lower pipe 304.

[0024] Reference Figure 3 Inside the tank shell 301, near the top of the rotating shaft 302, a fixed frame 308 is fixedly connected. A central shaft 306 is slidably connected at the center of the fixed frame 308. A gear plate 309 is provided at the bottom of the central shaft 306 and the top of the irregular gear 303.

A connecting rod 3061 is fixedly connected circumferentially to the outer side of the central shaft 306. A stirring arm 305 is fixedly connected to the other side of the connecting rod 3061.
[0025] Reference Figure 4 The eccentric gear 303 is eccentrically positioned, and the eccentric gear 303 meshes with the gear plate 309 through a toothed joint.
[0026] Reference Figure 2 , Figure 3 and Figure 4 One end of the rotating shaft 302 is connected to a motor. When the motor is turned on, the rotating shaft 302 rotates, which in turn drives the irregularly shaped gear 303 fixedly connected to it to rotate. Due to the eccentric connection of the irregularly shaped gear 303 on the rotating shaft 302, it will cause vertical displacement of the gear plate 309 in the vertical direction during rotation. At the same time, under the mutual meshing of the gear teeth, the gear plate 309 will also rotate. The vertical displacement of the gear plate 309 will be transmitted to the spring 307, causing the spring 307 to be stretched and compressed to a certain extent for buffering. The rotation of the gear plate 309 will continue to be transmitted to the central shaft 306 fixedly connected to it. The stirring arm 305 connected to the central shaft 306 through the connecting rod 3061 will also rotate continuously with it. The material is continuously stirred when it enters the tank shell 301 and during the entire transportation process. It is suitable for materials with a certain degree of adhesion and ensures the continuity and integrity of the material transportation process.
[0027] Reference Figure 5 The filter mechanism 1 includes a pipe shell 102 fixedly connected to the other end of the pipe 4, and a screen 101 is provided on the inner side of the other end of the pipe shell 102. The rebound cleaning mechanism 2 includes a limiting rod 201 fixedly connected to the outer surface of the tank shell 301 near the screen 101, and an outer cylinder 202 is fixedly connected to the bottom of the limiting rod 201.
[0028] Reference Figure 6 A top plate 203 is fixedly connected to the other side of the limiting rod 201. A slender rod 207 is fixedly connected to the bottom of the top plate 203. A rotating plate 3021 is rotatably connected to the other end of the rotating shaft 302 via a short shaft. A small base 2041 is rotatably connected to the top of the rotating plate 3021. A first layer plate 204 is fixedly connected to the bottom of the small base 2041. A spring 2071 is provided near the outside of the slender rod 207 at the bottom of the first layer plate 204. A second layer plate 2071 is fixedly connected to the bottom of the spring 2071. Plate 205, the bottom of the first plate 204 is slidably connected to the second plate 205 through the second plate 205 with a slender rod 208, the bottom of the second plate 205 is provided with a spring 2081 near the outside of the slender rod 208, the slender rod 207 passes through the first plate 204 and the second plate 205 and is fixedly connected to the bottom of the end near the spring 2081 with a base plate 206, the bottom of the second plate 205 is provided with a round rod 2051 passing through the base plate 206, and the bottom of the round rod 2051 is fixedly connected with a rubber block 209.
[0029] Reference Figure 5 , Figure 6 and Figure 7One end of the rotating shaft 302 is connected to a motor. When the motor starts, the rotation of the rotating shaft 302 is transmitted to the two connected rotating plates 3021 through a short rod. The rotation of the rotating plates 3021 and the small base 2041 together converts the rotation of the rotating shaft 302 into reciprocating motion in the vertical direction of the first plate 204 and the structure below it. The slender rod 207 slides from the top plate 203 through the first plate 204 and the second plate 205, and is finally fixedly connected to the bottom plate 206. After the rotating plate 3021 transmits displacement downward, the first plate 204 will compress the first spring 2071, and the spring will continue to compress the second plate 205. At the same time, the second plate 205 will also compress the second spring 2081. The second plate 205 drives the round rod 2051 and the rubber block 209 at its bottom downwards to complete the action of striking the tube shell 102. After falling, the rubber block 209 moves upwards under the traction of the rotating plate 3021 and the round rod 2051. At the same time, the second spring 2081 and the first spring 2071 also exert force to release the force that was just compressed, helping the second plate 205 and the round rod 2051 to move upwards. The second spring 2081 and the first spring 2071 play an auxiliary role in the up and down movement to complete the striking action and buffer the effect. Furthermore, due to the inertia of the springs, the first plate 204 can better complete the reciprocating motion, repeatedly striking the tube shell 102 to complete the cleaning of the dust cake on one side of the screen 101.
[0030] The working principle of this invention is as follows: First, the material is fed into the self-stirring tank mechanism 3. One end of the rotating shaft 302 is connected to a motor. After the motor is turned on, the rotating shaft 302 rotates, simultaneously driving the irregularly shaped gear 303 fixedly connected to it to rotate as well. Due to the eccentric connection of the irregularly shaped gear 303 on the rotating shaft 302, its rotation will cause a vertical displacement of the gear plate 309 in the vertical direction. At the same time, under the mutual meshing of the gear teeth, the gear plate 309 will also rotate. The vertical displacement of the gear plate 309 will be transmitted to the spring 307, causing the spring 307 to be stretched and compressed to a certain extent for buffering. The rotation of the gear plate 309 will continue to be transmitted to its fixed... The stirring arm 305, connected to the central shaft 306 via the connecting rod 3061, rotates continuously along with the central shaft 306. This continuous stirring occurs as the material enters the tank shell 301 and throughout the transportation process, making it suitable for materials with a certain degree of adhesion. This ensures the continuity and integrity of the material transportation process. Then, the suction valve 7 is activated to begin suction within the pipe 4, allowing the material to be transported within the pipe 4. A motor is connected to one end of the rotating shaft 302. When the motor starts, the rotation of the rotating shaft 302 is transmitted through a short rod to the two connected rotating plates 3021. The combined constraint of the rotating plates 3021 and the small base 2041 converts the rotation of the rotating shaft 302 into... The reciprocating motion of the first plate 204 and the structure below it in the vertical direction, the slender rod 207 slides from the top plate 203 through the first plate 204 and the second plate 205, and is finally fixedly connected to the bottom plate 206. After the rotating plate 3021 transmits displacement downward, the first plate 204 will compress the first spring 2071, and the spring will continue to compress the second plate 205. At the same time, the second plate 205 will also compress the second spring 2081. The second plate 205 will drive the round rod 2051 and the rubber block 209 at its bottom downward, completing the action of striking the tube shell 102. After falling, the rubber block 209 moves upward under the traction of the rotating plate 3021 and the round rod 2051, and at the same time, the second spring 2081... 1 and spring 2071 also exert force synchronously to release the force that was just compressed, helping the second plate 205 and the round rod 2051 to move upward. Spring 2081 and spring 2071 play an auxiliary role in the up-and-down movement to complete the knocking action and buffer the effect. In addition, due to the inertia of the spring, it can help the first plate 204 to complete the reciprocating motion better, knocking the tube shell 102 multiple times to clean the dust cake on one side of the screen 101, so that the material can be transported more smoothly in the pipe 4 and finally reach the negative pressure adsorption tank 6 for collection. After the overall transportation is completed, the suction valve 7 is closed, the opening at the bottom of the negative pressure adsorption tank 6 is opened, and the material is transferred to the receiving tank 5, completing the entire transportation.
[0031] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
