Description

Technical Field

[0001] This utility model relates to the field of new energy materials, and in particular to an iris valve for spiral filling. Background Technology

[0002] In existing technologies, high-precision control of automatic filling technology has not yet been achieved in the production process of new energy materials. Powder and material leakage frequently occur during automatic filling, leading to high dust concentrations in the environment, posing significant safety hazards, and causing environmental pollution and harm to workers' health. Currently, traditional ultrafine powder spiral filling equipment in the market often inserts itself deep into containers such as crucibles, saggers, or bags, and the filling operation is achieved by adjusting the spiral's speed and start / stop. Due to the limitations of the containers being filled, there is no corresponding valve to control the opening and closing of the outlet. Because ultrafine powders have excellent flowability, and the filling port needs to be installed vertically during the filling process, material cannot be effectively closed, resulting in leakage and uncontrollable metering accuracy. Utility Model Content

[0003] This application provides an iris valve for spiral filling, solving the problem in the prior art where the outlet end lacks a corresponding valve to control the opening and closing of the outlet due to the limitations of the container to be filled. Because ultrafine powders have good flowability, and the filling port needs to be installed vertically during the filling process, material cannot be effectively closed, leading to leakage and uncontrollable metering accuracy.

[0004] The technical solutions adopted in the embodiments of this application are as follows.

[0005] A spiral-filled iris valve includes a valve body and a cylinder drive device. The valve body includes a lower valve seat mounting plate, a valve seat main body, an upper valve seat mounting plate, a housing, a drive bracket, a housing support frame, and several valve plates. The lower valve seat mounting plate, valve seat main body, upper valve seat mounting plate, housing, drive bracket, housing support frame, and several valve plates are all arranged in a circular array around the same axis. The cylinder drive device includes a cylinder main body, a cylinder sliding cylinder body, and a cylinder mounting frame, arranged in a regular polygonal pattern. The lower valve seat mounting plate and valve seat main body are provided with several sets of guide grooves, which are arranged in a regular polygonal pattern. The several valve plates are arranged in a circular or... The valve plate is a regular polygon with guide posts that allow it to move linearly back and forth along the guide groove. A drive bracket connects the cylinder sliding body and the valve plate to transmit driving force. The cylinder sliding body is driven by compressed air and moves linearly back and forth. A housing support frame is installed between the valve seat body and the valve seat mounting plate. The outer shell is mounted on the housing support frame in a circular arrangement. The valve seat body and the valve seat mounting plate have grooves to fit the housing support frame and the outer shell. The cylinder drive device is driven by compressed air, causing several valve plates to move along the guide groove, resulting in the valve plates opening and closing around a central axis.

[0006] As a further improvement to the above technical solution: The configuration of the lower valve seat mounting plate, valve seat body, upper valve seat mounting plate, outer shell support frame, and outer shell enables the iris valve to be installed from bottom to top on the discharge port of the spiral filling.

[0007] The cylinder body is equipped with a position sensor for reading the real-time position of any set of valve plates.

[0008] The lower mounting plate, valve seat body, and upper mounting plate of the valve seat are made of metal or high-strength non-metallic materials such as P-type steel, polytetrafluoroethylene, nylon, polyethylene, and carbon fiber.

[0009] The valve plate is made of high-strength non-metallic materials such as acetal, polytetrafluoroethylene, nylon, polyethylene, and carbon fiber, or is made of metal material with a smooth surface treatment.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. Utilizing a valve plate design that opens and closes around a central axis via an iris valve, this system effectively shuts off ultrafine powder materials, fundamentally solving the leakage problems caused by the lack of outlet valve control in traditional spiral filling equipment. This significantly improves metering accuracy during automatic filling, meeting high-precision control requirements. The valve body components are arranged circularly around the same axis, while the cylinder drive unit is arranged in a regular polygonal pattern. The overall structure is perfectly adaptable to powder filling applications. Furthermore, after the valve opens, the valve plate moves to a position that does not obstruct material flow, eliminating structural barriers and effectively solving problems such as material accumulation and bridging that affect conveying. Using compressed air as the power source for valve plate opening and closing avoids the safety hazards of dust explosions that could occur with motor-driven systems in high-dust environments. It also ensures stable operation of the equipment in such special environments, providing strong protection for production safety. The configuration of components such as the lower valve seat mounting plate, valve seat body, and upper valve seat mounting plate allows the iris valve to be installed from bottom to top on the discharge port of the spiral-filled material, facilitating installation. Furthermore, the valve seat body and upper valve seat mounting plate are equipped with grooves to fit the outer shell support frame and the outer shell, effectively isolating dust and reducing dust overflow. By eliminating powder and material leakage and dust overflow, not only is environmental pollution from dust avoided, but also the health hazards of dust to workers are prevented, meeting environmental protection and occupational health requirements. A position sensor on the cylinder body can read the real-time position of the valve plate, helping to more accurately control the opening and closing state of the valve plate, further ensuring the reliability and stability of valve operation.

[0015] This application provides an iris valve for spiral filling, solving the problem in the prior art where the outlet end lacks a corresponding valve to control the opening and closing of the outlet due to the limitations of the container to be filled. Because ultrafine powders have good flowability, and the filling port needs to be installed vertically during the filling process, material cannot be effectively closed, leading to leakage and uncontrollable metering accuracy.

The valve body includes a lower valve seat mounting plate 1, a valve seat body 3, an upper valve seat mounting plate 4, a housing 7, a drive bracket 8, a housing support frame 6, and several valve plates 2. The lower valve seat mounting plate 1, the valve seat body 3, the upper valve seat mounting plate 4, the housing 7, the drive bracket 8, the housing support frame 6, and the several valve plates 2 are all arranged in a circular array around the same axis. The cylinder drive device 5 includes a cylinder body 51, a cylinder sliding cylinder body 52, and a cylinder mounting frame 53, arranged in a regular polygonal pattern. The lower valve seat mounting plate 1 and the valve seat body 3 are provided with several sets of guide grooves, which are arranged in a regular polygonal pattern. The several valve plates 2 are arranged around the same axis. The valve plates are arranged in a linear array, in a circular or regular polygonal shape. The valve plate 2 is provided with guide posts, which cause the valve plate 2 to move back and forth in a straight line along the guide groove. The drive bracket 8 connects the cylinder sliding cylinder body 52 and the valve plate 2 to transmit the driving force. The cylinder sliding cylinder body 52 is driven by compressed air and moves back and forth in a straight line. The outer shell support frame 6 is installed between the valve seat body 3 and the valve seat mounting plate 4. The outer shell 7 is installed on the outer shell support frame 6 and is arranged in a circular shape. The valve seat body 3 and the valve seat mounting plate 4 are provided with grooves to fit the outer shell support frame 6 and the outer shell 7. The cylinder drive device 5 is driven by compressed air, which causes several valve plates 2 to move along the guide groove, so that several valve plates 2 are in an opening and closing state around the central axis.

[0018] The configuration of the lower valve seat mounting plate 1, valve seat body 3, upper valve seat mounting plate 4, outer shell support frame 6, and outer shell 7 enables the iris valve to be installed from bottom to top on the discharge port of the spiral filling.

[0019] A position sensor is provided on the cylinder body 51 to read the real-time position of any set of valve plates 2.

[0020] The lower mounting plate 1, the valve seat body 3, and the upper mounting plate 4 of the valve seat are made of metal or high-strength non-metallic materials such as P-type steel, polytetrafluoroethylene, nylon, polyethylene, and carbon fiber.

[0021] Valve plate 2 is made of high-strength non-metallic materials such as acetal, polytetrafluoroethylene, nylon, polyethylene, and carbon fiber, or is made of metal material with a smooth surface treatment.

[0022] Thanks to the design of the valve plate 2, which opens and closes around the central axis via an iris valve, it effectively shuts off ultrafine powder materials, fundamentally solving the problem of powder and material leakage caused by the lack of valve control at the outlet in traditional spiral filling equipment. This significantly improves the metering accuracy during automatic filling and meets the requirements for high-precision control. The valve body components are arranged in a circle around the same axis, while the cylinder drive device 5 is arranged in a regular polygon. The overall structure is fully adaptable to powder filling applications. Furthermore, after the valve opens, the valve plate 2 moves to a position that does not obstruct material flow, effectively solving problems such as material accumulation and bridging that affect conveying. Using compressed air as the power source to drive the valve plate 2 avoids the safety hazards such as dust explosions that may occur in high-dust environments caused by motor drives, while also ensuring stable operation of the equipment in such special environments, providing strong protection for production safety. The configuration of components such as the lower valve seat mounting plate 1, valve seat body 3, and upper valve seat mounting plate 4 allows the iris valve to be installed from bottom to top on the discharge port of the spiral filling machine, making installation convenient. Furthermore, the valve seat body 3 and upper valve seat mounting plate 4 are equipped with grooves to fit the housing 7 support frame 6 and housing 7, effectively isolating dust and reducing dust overflow. By eliminating powder and material leakage and dust overflow, not only is dust pollution to the environment avoided, but also the health hazards to workers caused by dust are prevented, meeting environmental protection and occupational health requirements. The position sensor installed on the cylinder body 51 can read the real-time position of the valve plate 2, helping to more accurately control the opening and closing state of the valve plate 2, further ensuring the reliability and stability of valve operation.
