Description

Technical Field

[0001] This invention relates to the field of pipeline material conveying technology, specifically to a device that enables automatic connection of equipment after pipeline pressurization and long-distance rapid conveying of materials such as powder and granules. Background Technology

[0002] During pipeline pressurization and conveying, while maintaining the pressure within the pipeline, automatic connection or disconnection of the output port is not possible, nor is automatic opening and closing of the inlet and outlet valves. Automatic connection of the output port and automatic opening of the valves are also impossible, requiring manual pipeline connection. Furthermore, the pressure within the pipeline must be reduced to atmospheric pressure before pressurization can proceed. After material conveying is complete, automatic valve closure and automatic disconnection of the output port are also impossible, requiring manual pipeline connection and disconnection. Disconnection also requires reducing the pressure within the pipeline to atmospheric pressure. This manual operation is inefficient, and connection reliability cannot be guaranteed. A single person cannot maintain continuous machine operation, thus reducing production efficiency.

[0003] Therefore, the present invention provides a device that enables automatic connection of equipment after pipeline pressurization and long-distance rapid transportation of materials such as powder and granules. Summary of the Invention

[0016] 1. This device, which enables automatic connection of equipment after pipeline pressurization and long-distance rapid conveying of materials such as powder and granules, uses guide rails, sliders, first baffles, and second baffles respectively set between the first, second, and third mounting plates. This allows the lifting assembly mounted on the top of the third mounting plate to move in four directions: left, right, forward, and backward. Simultaneously, the guide rods and springs enable the lifting assembly to automatically center and return to its original position, thereby achieving displacement compensation between the lifting assembly and the docking cone sleeve assembly, facilitating the docking of the tank's docking cone sleeve with the centering cone sleeve. Furthermore, the base sealing cover can protect against dust, particles, and debris, ensuring the normal sliding of the guide rails and sliders.

[0017] 2. This device, which enables automatic connection of equipment after pipeline pressurization and long-distance rapid conveying of materials such as powder and granules, uses a cylinder to raise and lower the floating joint seat of the feed, facilitating docking between the floating joint seat and the docking cone sleeve of the tank. A guide rod vertically guides the floating joint seat, allowing it to move up and down. When the guide rod moves the slide upward, it compresses the nitrogen spring, which in turn compresses the docking dust cover, allowing it to open to both sides. Conversely, the dust cover closes and seals the centering cone sleeve, providing dust protection. A small cylinder and a stainless steel coated head allow for the air pressure input port on the docking cone sleeve of the tank to facilitate opening the valve for feeding.

[0018] 3. This device, which enables automatic connection of equipment after pipeline pressurization and long-distance rapid conveying of materials such as powder and granules, achieves automatic connection between the output port of the material storage equipment and the input port of the mixing equipment through the cooperation of the base assembly, lifting assembly and receiving cone sleeve assembly. It also automatically opens the feed valve, replacing manual operation, and ensures continuous pressurization inside the pipeline to prevent air leakage. This allows for stable long-distance and high-speed conveying of materials such as powder and granules, facilitating continuous machine operation and improving production efficiency.

The base dust cover 112 is in close contact with the outer wall of the third mounting plate 115. The guide rod 120 can limit the second baffle 119, so that the second mounting plate 114 can slide in the left and right directions under the guidance of the guide rail 116 and the slider 117, and the third mounting plate 115 can slide in the front and back directions. The guide rod 120 and the spring 121 can reset the second mounting plate 114 and the third mounting plate 115, which facilitates displacement compensation of the lifting assembly 2. The base dust cover 112 can block debris and dust, so as to prevent them from affecting the use of the guide rail 116 and the slider 117.

[0033] In this embodiment, a conical sleeve spring is fixedly installed at the bottom of the feeding floating joint 223. The conical sleeve spring is installed inside the feeding floating joint seat 215. A feeding floating joint cover plate 214 is fixedly installed at the top of the feeding floating joint seat 215 corresponding to the top of the conical sleeve spring. A floating joint sealing ring 226 is tightly fitted at the bottom of the feeding floating joint 223. A first feeding transistor seat 224 is fixedly installed at the bottom of the floating joint sealing ring 226.

The second feed transistor base 225 is fixedly installed inside the guide seat 216. The feed floating joint 223 can be eccentrically adjusted inside the feed floating joint seat 215 by the set cone sleeve spring, which facilitates the docking between the centering cone sleeve 213 and the tank docking cone sleeve 31. The sealing performance of the lifting assembly 2 can be improved by the floating joint sealing ring 226 and the polymer wear-resistant sealing tube, which facilitates the discharge of materials.

[0034] In this embodiment, the two ends of the cylinder 217 are respectively fixedly installed on the front and rear sides of the guide seat 216 between the support seat 211 and the feed floating joint seat 215.

Mounting seats 220 are symmetrically fixed on both sides of the top of the guide seat 216. The docking dust cover 221 is movably installed on the top of the mounting seat 220 via a rotating shaft. The top of the nitrogen springs 222 is movably connected to both ends of the docking dust cover 221. The docking dust cover 221 is located on both sides of the centering cone sleeve 213. The guide rods 218 are slidably installed inside the mounting seat 220. A valve opening and closing assembly 212 is fixedly installed at the front end of the feed floating joint seat 215. The valve opening and closing assembly 212 includes a small cylinder and a stainless steel coated head. The small cylinder is fixedly installed on the feed floating joint seat 215. At the front end of the joint seat 215, the stainless steel rubber-coated head is fixedly installed at the top of the output rod of the small cylinder. The cylinder 217 can adjust the height of the feeding floating joint seat 215. The guide rod 218 can guide the feeding floating joint seat 215, improving its stability. When the guide rod 218 rises, it can drive the slide seat 219 to move upwards synchronously. The slide seat 219 squeezes the docking dust cover 221 through the nitrogen spring 222, so that the docking dust cover 221 can rotate and open on both sides of the mounting seat 220, facilitating docking between the centering cone sleeve 213 and the tank docking cone sleeve 31. When the guide rod 218 slides down, it can pull the docking dust cover 221 to rotate in the opposite direction and close through the slide seat 219 and the nitrogen spring 222, facilitating dust prevention for the centering cone sleeve 213. The valve opening and closing assembly 212 can open and close the valve at the bottom of the storage tank, thereby conveying materials.

[0035] In this embodiment, an installation hole is provided at the center of the tank docking cone sleeve 31. A flange mounting gasket 33 is fixedly installed inside the installation hole. A silicone gasket 35 is fixedly provided on the lower outer side of the flange mounting gasket 33 corresponding to the bottom inside of the tank docking cone sleeve 31. The tank docking cone sleeve 31 can be fixedly connected to the bottom outlet of the tank through a threaded screw 34. The flange mounting gasket 33 can improve the sealing between the docking cone sleeve assembly and the tank. The silicone gasket 35 can improve the sealing between the tank docking cone sleeve 31 and the centering cone sleeve 213, preventing air leakage and affecting the material conveying.

[0036] When using this device, which enables automatic connection of equipment after pipeline pressurization and long-distance rapid conveying of materials such as powder and granules, the base plate 111 is fixed by having through holes inside, and the base assembly 1 is fixedly installed. The lifting assembly 2 is fixed to the top of the base assembly 1 by the fixed connection between the support base 211 and the third mounting plate 115. The base assembly 1 and the lifting assembly 2 are installed below the discharge port of the storage tank, and the tank body docking cone sleeve 31 is fixedly connected to the discharge port flange of the storage tank by a threaded screw 34. The pneumatic quick connector 32 is connected to the start valve on the discharge port of the storage tank through a pipeline. The lifting assembly 2 and the base assembly 1 are located at the discharge port of the storage tank and the tank body docking cone sleeve 31. Below position 1, the feed hose seat assembly 227 is fixedly connected to the feed pipe of the mixing equipment. The feed hose seat assembly 227, the second feed transistor seat 225, the first feed transistor seat 224, and the feed floating joint 223 are composed of organic polymer materials. During feeding, the cylinder 217 is controlled and activated. The cylinder 217 pushes the feed floating joint seat 215 upward, and the feed floating joint seat 215 drives the guide rod 218 to move. The guide rod 218 can guide and limit the feed floating joint seat 215, which can improve the stability of the feed floating joint seat 215. At the same time, the feed floating joint seat 215 can drive the feed floating joint 223 and the centering cone sleeve 213 to move upward. Furthermore, the centering cone sleeve 213 and the feeding floating joint 223 can be inserted into the bottom end of the tank docking cone sleeve 31, and the silicone gasket 35 can seal the centering cone sleeve 213 and the feeding floating joint 223 with the tank docking cone sleeve 31. At the same time, the polymer wear-resistant sealing tube expands and contracts, and the feeding floating joint seat 215 will also drive the valve opening and closing assembly 212 to move upward. The small cylinder pushes the stainless steel rubber-coated head to press against the air pressure input port at the bottom of the tank docking cone sleeve 31 and connect to the pneumatic quick connector 32. The air pressure is delivered to open the start valve on the discharge port of the storage tank, so that the material inside the storage tank passes through the discharge port, the tank docking cone sleeve 31, the feeding floating joint 223, and the first feeding transistor seat 22. 4. The second feed transistor base 225, the polymer wear-resistant sealed tank, and the feed hose base assembly 227 are discharged into the pipeline and mixing equipment, which facilitates the stable long-distance and high-speed conveying of powder, granular materials and other materials, and facilitates the continuous operation of the machine, thereby improving production and processing efficiency. The guide rail 116 and the slider 117 can move and adjust the second mounting plate 114 and the third mounting plate 115 when the centering cone sleeve 213 and the tank docking cone sleeve 31 are offset, and drive the lifting assembly 2 to slide in four directions: left, right, forward and backward. The guide rod 120 and the spring 121 can center and return the lifting assembly 2 to its original position, which facilitates the docking between the centering cone sleeve 213 and the tank docking cone sleeve 31.When the guide rod 218 moves upward, it can drive the slide 219 to compress the nitrogen spring 222. The nitrogen spring 222 can push the docking dust cover 221 to rotate and open on both sides of the mounting base 220, facilitating the docking of the centering cone sleeve 213 and the tank docking cone sleeve 31. When the guide rod 218 and the slide 219 move downward, they can pull the nitrogen spring 222 and pull the docking dust cover 221, causing the docking dust cover 221 to rotate in the opposite direction and close, thus achieving the function of dust prevention.
