Technical Field

[0001] The utility model relates to the technical field of material conveying and distributing devices, in particular to a rotary intelligent switching valve. Background Art

[0002] In many industrial production processes, it's common to switch between different material flow paths to meet production process requirements. Traditional manual switching methods are not only time-consuming and labor-intensive, but also prone to operator errors, resulting in unstable product quality. Furthermore, manual switching poses safety risks, especially when handling corrosive or toxic substances. To address these issues, automated switching valves are increasingly being introduced into production lines.

[0003] The existing switching valve has the following problems:

[0004] Complex structure: Many switching valves have complex designs and high maintenance costs.

[0005] Poor sealing performance: Leakage is likely to occur during the switching process, affecting the purity of the material and the safety of the production environment.

[0006] Low switching accuracy: It is difficult to ensure that each switching is accurate, especially when the material ratio needs to be precisely controlled.

[0007] Large space occupation: Some switching valves are large in size and are not suitable for installation in places with limited space. Utility Model Content

[0008] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a rotary intelligent switching valve to solve the problems of complex structure, poor sealing performance and low switching accuracy of the material switching valve in the prior art.

[0009] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions:

[0010] A rotary intelligent switching valve includes a rotary chamber, a shell located on the periphery of the rotary chamber and coaxially arranged with the rotary chamber, and a driving device that drives the rotary chamber to rotate in the shell; the rotary chamber is provided with a first feed port, a second feed port and a discharge port; the shell is provided with a feed pipe, a first discharge pipe and a second discharge pipe; the rotation of the rotary chamber can enable the feed pipe to switch between connecting to the first feed port or the second feed port, and at the same time enable the discharge port to switch between connecting to the first discharge pipe or the second discharge pipe.

[0011] To implement the above technical solution, the swirl chamber is located inside the shell, and the two are coaxially arranged, and the swirl chamber is provided with a first feed port, a second feed port and a discharge port; the shell is fixed, and a feed pipe, a first discharge pipe and a second discharge pipe are provided thereon, and a driving device is connected and drives the swirl chamber to rotate in the shell. By accurately controlling the position of the swirl chamber, the connection state between each opening on the swirl chamber and the pipeline on the shell can be changed. The feed pipe can switch to connect to the first feed port or the second feed port, and the discharge port can also switch between the first discharge pipe or the second discharge pipe, so as to realize the raw material transportation and distribution between different pipelines. The switching of material channels is carried out in an automated manner, which reduces the time and complexity of manual operation and significantly improves the work efficiency in the production process; the device is applicable to various types of materials (liquids, gases, solid particles, etc.), and can adjust the size and configuration according to different application scenarios, with high flexibility; accurate material control helps to avoid problems such as excessive feeding or uneven mixing, reduces raw material waste and saves costs; by accurately controlling the material ratio, it helps to improve the quality consistency of the final product, which is particularly important for products that are sensitive to the ratio of raw materials. This application is mainly used in various raw material conveying pipelines and processing machinery that need to convey raw materials. After installing this switching valve at the front end of the conveying pipeline, an automated batching process can be realized.

[0012] In one embodiment of the present invention, initially, the first feed port is connected to the feed pipe, and the discharge port is connected to the first discharge pipe; after switching, the second feed port is connected to the feed pipe, and the discharge port is connected to the second discharge pipe.

[0013] Implementing the above technical solution, the design allows for quick and accurate switching of different material flow paths without interrupting the production process, thereby improving the flexibility and efficiency of the production line. Through precise control of the drive device, it can be ensured that each switch is accurate, thereby ensuring the correct ratio and conveying path between different materials. Accurate material switching helps maintain product consistency and quality, which is particularly important in processes that require strict control of raw material ratios.

[0014] In one embodiment of the present invention, a clamping ring for limiting the rotation cavity is provided at the upper end of the shell, and a bottom plate is provided at the lower end of the shell.

[0015] To implement the above technical solution, a retaining ring is located at the upper end of the housing to limit the vertical movement of the swirling chamber. The retaining ring prevents the swirling chamber from dislodging from the housing and ensures that it maintains the correct axial position during rotation. The base plate is located at the lower end of the housing, providing a stable support surface for the swirling chamber to rotate smoothly and also acting as a seal to prevent material leakage. The retaining ring and base plate work together to ensure the correct position of the swirling chamber within the housing, avoiding potential safety hazards caused by positional deviation.

[0016] In one embodiment of the present invention, the driving device includes a cylinder fixing plate arranged on the retaining ring, and a cylinder arranged on the cylinder fixing plate. The output shaft of the cylinder is hinged with a connecting rod. A connecting block is provided at the top axis of the rotation chamber, and the connecting rod is passed through and fastened to the connecting block.

[0017] To implement the above technical solution, the cylinder fixing plate is mounted on a retaining ring, providing a stable mounting platform for the cylinder. The cylinder is mounted on the cylinder fixing plate, and the rotation of the swirl chamber is driven by the expansion and contraction of the output shaft. One end of the connecting rod is hinged to the cylinder's output shaft, and the other end is passed through and fastened to the connecting block at the top axis of the swirl chamber. The function of the connecting rod is to convert the linear motion of the cylinder into the rotational motion of the swirl chamber. When the cylinder is working, its output shaft pushes the connecting rod, thereby driving the rotation of the swirl chamber. The design of the cylinder drive and connecting rod transmission can achieve precise control of the rotation angle of the swirl chamber, ensuring that each switching is accurate.

[0018] In one embodiment of the present invention, the second feed port is located between the first feed port and the discharge port.

[0019] To implement the above technical solution, the second feed port is located between the first feed port and the discharge port, making the design of the entire swirl chamber more compact, reducing space occupancy, and suitable for limited space layout; since the position of the second feed port is more reasonable, the flow channel design inside the swirl chamber can be simplified, reducing unnecessary complexity, improving the convenience of manufacturing and maintenance, and making the swirl chamber smoother during the switching process.

[0020] In one embodiment of the present invention, the second discharge pipe is located between the feed pipe and the first discharge pipe.

[0021] To implement the above technical solution, the second feed port is located between the first feed port and the discharge port, and the second discharge pipe is located between the feed pipe and the first discharge pipe, making the design of the entire rotary cavity more compact, reducing space occupancy, suitable for limited space layout, and making switching operations faster and more accurate, reducing downtime in the production process.

[0022] In one embodiment of the present invention, the included angle between the axes of the first feed port and the second feed port is equal to the included angle between the axes of the first discharge pipe and the second discharge pipe.

[0023] This design, which implements the aforementioned technical solution, ensures that when the swirling chamber switches its feed port during rotation, the discharge pipe automatically aligns with the other. This ensures that the fluid flows from the selected feed port, passes through the swirling chamber, and then exits the corresponding discharge pipe. Since the feed port and discharge pipe switch synchronously, switching time is reduced and production efficiency is improved. During the switching process, each port is precisely aligned, preventing leakage or blockage caused by misalignment.

[0024] In one embodiment of the present invention, sealing rings are embedded in the inner walls of the first feed port, the second feed port, and the discharge port.

[0025] To implement the above technical solution, these sealing rings maintain close contact with the housing during the rotational switching of the revolving chamber, forming a sealing surface to prevent fluid leakage during the switching process. This ensures overall sealing performance, effectively prevents cross-contamination between different fluid paths, ensures material purity, and reduces the risk of leakage, thereby improving operational safety, preventing accidents caused by leakage, and helping to protect the environment, meeting the environmental protection requirements of modern industry.

[0026] In one embodiment of the present invention, the first feed port and the discharge port are arranged opposite to each other, and the feed pipe and the first discharge pipe are arranged opposite to each other.

[0027] To implement the above technical solution, the relative design reduces the path of the fluid from the feed pipe to the discharge port, reduces the resistance and residence time of the material in the swirl chamber, and helps prevent the retention and deposition of the material inside the swirl chamber.

[0028] In one embodiment of the present invention, the rotation cavity is cylindrical.

[0029] To implement the above technical solution, the rotation cavity is designed to be cylindrical. This geometric shape helps to achieve smooth rotational motion and fluid flow. The cylindrical rotation cavity is easy to process and manufacture, which reduces production costs and makes it easier to ensure manufacturing accuracy. The cylindrical design makes the rotation cavity more balanced during the rotation process, reduces vibration and wear, and improves the stability and reliability of equipment operation.

[0030] As described above, the rotary intelligent switching valve of the present invention has the following beneficial effects:

[0031] High degree of automation: Through automated control, the rotary intelligent switching valve can achieve precise material switching without manual intervention, improving production efficiency and safety

[0032] Compact structure: The cylindrical rotation cavity design makes the entire device more compact, reduces space occupancy, and is suitable for installation in places with limited space.

[0033] Strong flexibility: This application can adjust the size and configuration according to different application scenarios, and has high flexibility.

[0034] Precise control: Precise material control helps avoid problems such as overdosing or uneven mixing, and helps improve the consistency of final product quality, which is especially important for products that are sensitive to raw material ratios.

[0035] Reduce idle time: Since the switching of the feed port and the discharge pipe is synchronized, the time required for switching can be reduced and production efficiency can be improved; it ensures that the various interfaces can be accurately aligned during the switching process, avoiding leakage or blockage caused by misalignment.

[0036] Enhanced sealing: Sealing rings are embedded in the inner walls of the feed port and the discharge port to ensure the sealing of the connection, effectively prevent material leakage, and improve the overall sealing performance.

[0037] Strong adaptability: The rotary cavity is designed to be cylindrical. This geometric shape helps to achieve smooth rotational motion and fluid flow, and is suitable for various types of materials (liquids, gases, solid particles, etc.). BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless there is a conflict.

[0043] See also Figures 1 to 2The utility model provides a rotary intelligent switching valve, comprising a rotary chamber 1, a shell 2 located on the periphery of the rotary chamber 1 and coaxially arranged with the rotary chamber 1, and a driving device for driving the rotary chamber 1 to rotate in the shell 2; the rotary chamber 1 is provided with a first feed port 3, a second feed port 4 and a discharge port 5; the shell 2 is provided with a feed pipe 6, a first discharge pipe 7 and a second discharge pipe 8; the rotation of the rotary chamber 1 can enable the feed pipe 6 to switch between connecting to the first feed port 3 or the second feed port 4, and at the same time enable the discharge port 5 to switch between connecting to the first discharge pipe 7 or the second discharge pipe 8.

[0044] The swirl chamber 1 is located inside the shell 2 and the two are coaxially arranged. The swirl chamber 1 is provided with a first feed port 3, a second feed port 4, and a discharge port 5. The shell 2 is fixed and is provided with a feed pipe 6, a first discharge pipe 7, and a second discharge pipe 8. A drive device is connected to and drives the swirl chamber 1 to rotate within the shell 2. By precisely controlling the position of the swirl chamber 1, the connection between the various openings on the swirl chamber 1 and the pipes on the shell 2 can be changed. The feed pipe 6 can switch to connect to the first feed port 3 or the second feed port 4, and the discharge port 5 can also switch between the first discharge pipe 7 and the second discharge pipe 8, realizing the transportation and distribution of raw materials between different pipelines. By switching material channels in an automated manner, the time and complexity of manual operations are reduced, and the work efficiency in the production process is significantly improved; the device is suitable for various types of materials (liquids, gases, solid particles, etc.), and the size and configuration can be adjusted according to different application scenarios, with high flexibility; precise material control helps to avoid problems such as overfeeding or uneven mixing, reduces raw material waste, and saves costs; by precisely controlling the material ratio, it helps to improve the quality consistency of the final product, which is especially important for those products that are sensitive to the raw material ratio. This application is mainly used in various raw material conveying pipelines and processing machinery that need to convey raw materials. After installing this switching valve at the front end of the conveying pipeline, an automated batching process can be achieved.

[0045] Initially, the first feed port 3 is connected to the feed pipe 6 , and the discharge port 5 is connected to the first discharge pipe 7 ; after switching, the second feed port 4 is connected to the feed pipe 6 , and the discharge port 5 is connected to the second discharge pipe 8 .

[0046] When the swirling chamber 1 is in its initial position, the feed pipe 6 on the housing 2 is aligned with and connected to the first feed port 3 on the swirling chamber 1. This means that raw materials can enter the swirling chamber 1 through the feed pipe 6 and flow into the interior of the swirling chamber 1 through the first feed port 3. At the same time, in this state, the discharge port 5 on the swirling chamber 1 is aligned with and connected to the first discharge pipe 7 on the housing 2. In this way, the raw materials entering the swirling chamber 1 can flow out through the discharge port 5 and be transported to the next processing step or destination through the first discharge pipe 7.

[0047] When the material channel needs to be switched, the drive device rotates the swirl chamber 1 to a new position, aligning and connecting the feed pipe 6 on the housing 2 with the second feed port 4 on the swirl chamber 1. At this point, the raw material can enter the swirl chamber 1 through the feed pipe 6 and flow into the interior of the swirl chamber 1 through the second feed port 4. Similarly, in this new position, the discharge port 5 on the swirl chamber 1 is aligned and connected with the second discharge pipe 8 on the housing 2. In this way, the raw material entering the swirl chamber 1 can flow out through the discharge port 5 and be transported to another processing step or destination through the second discharge pipe 8.

[0048] This design allows for quick and accurate switching of different material flow paths without interrupting the production process, improving the flexibility and efficiency of the production line. Precise control of the drive device ensures that each switch is accurate, thereby ensuring the correct ratio and conveying path between different materials. Accurate material switching helps maintain product consistency and quality, which is particularly important in processes that require strict control of raw material ratios.

[0049] The upper end of the shell 2 is provided with a retaining ring 9 for limiting the rotation chamber 1, and the lower end of the shell 2 is provided with a bottom plate 10. The retaining ring 9 is located at the upper end of the shell 2, and is used to limit the movement of the rotation chamber 1 in the vertical direction. The design of the retaining ring 9 can prevent the rotation chamber 1 from escaping from the shell 2 and ensure that it maintains the correct axial position during the rotation process; the bottom plate 10 is located at the lower end of the shell 2, providing a stable support surface so that the rotation chamber 1 can rotate smoothly, and the bottom plate 10 can also play a sealing role to prevent material leakage; the retaining ring 9 and the bottom plate 10 work together to ensure the correct position of the rotation chamber 1 in the shell 2, avoiding potential safety hazards caused by position deviation.

[0050] The driving device includes a cylinder 12 fixing plate 11 arranged on the retaining ring 9, and a cylinder 12 arranged on the cylinder 12 fixing plate 11. The output shaft of the cylinder 12 is hinged with a connecting rod 13. A connecting block 14 is provided at the top axis of the rotation chamber 1, and the connecting rod 13 is passed through and fastened to the connecting block 14.

[0051] The fixing plate 11 of the cylinder 12 is mounted on the retaining ring 9, providing a stable mounting platform for the cylinder 12. The cylinder 12 is mounted on the fixing plate 11 of the cylinder 12, and the rotation of the revolving chamber 1 is driven by the extension and contraction of the output shaft. One end of the connecting rod 13 is hinged on the output shaft of the cylinder 12, and the other end is passed through and fastened to the connecting block 14 at the top axis of the revolving chamber 1. The function of the connecting rod 13 is to convert the linear motion of the cylinder 12 into the rotational motion of the revolving chamber 1. When the cylinder 12 is working, its output shaft pushes the connecting rod 13, thereby driving the revolving chamber 1 to rotate. Through the design of the cylinder 12 drive and the connecting rod 13 transmission, the rotation angle of the revolving chamber 1 can be accurately controlled to ensure that each switch is accurate.

[0052] The second feed port 4 is located between the first feed port 3 and the discharge port 5. The second feed port 4 is located between the first feed port 3 and the discharge port 5, making the design of the entire swirling chamber 1 more compact, reducing space occupation, and being suitable for limited space layout; due to the more reasonable position of the second feed port 4, the flow channel design inside the swirling chamber 1 can be simplified, reducing unnecessary complexity, improving the convenience of manufacturing and maintenance, and making the swirling chamber 1 smoother during the switching process.

[0053] The second discharge pipe 8 is located between the feed pipe 6 and the first discharge pipe 7. The second feed port 4 is located between the first feed port 3 and the discharge port 5, and the second discharge pipe 8 is located between the feed pipe 6 and the first discharge pipe 7, making the design of the entire rotary chamber 1 more compact, reducing space occupation, suitable for limited space layout, and making switching operations faster and more accurate, reducing downtime during the production process.

[0054] The angle between the axes of the first feed port 3 and the second feed port 4 is equal to the angle between the axes of the first discharge pipe 7 and the second discharge pipe 8. This design ensures that when the feed port of the rotary chamber 1 switches during rotation, the discharge pipes automatically align, ensuring that the fluid flows from the selected feed port, passes through the rotary chamber 1, and then flows out of the corresponding discharge pipe. Because the switching of the feed port and discharge pipe is synchronized, the time required for switching is reduced, improving production efficiency. It also ensures that the various interfaces are precisely aligned during the switching process, avoiding leakage or blockage caused by misalignment.

[0055] Sealing rings 15 are embedded in the inner walls of the first feed port 3, the second feed port 4, and the discharge port 5. These sealing rings 15 maintain close contact with the housing 2 during the rotational switching of the revolving chamber 1, forming a sealing surface to prevent fluid leakage during the switching process. This ensures overall sealing performance, effectively prevents cross-contamination between different fluid paths, ensures material purity, and reduces the risk of leakage, thereby improving operational safety, preventing accidents caused by leakage, and helping to protect the environment, meeting the environmental protection requirements of modern industry.

[0056] The first feed port 3 is arranged opposite to the discharge port 5, and the feed pipe 6 is arranged opposite to the first discharge pipe 7. The relative arrangement design shortens the path of the fluid from the feed pipe 6 to the discharge port 5, reduces the resistance and residence time of the material in the swirl chamber 1, and helps prevent the retention and deposition of the material inside the swirl chamber 1.

[0057] The swirling cavity 1 is cylindrical. This cylindrical geometry facilitates smooth rotational motion and fluid flow. The cylindrical swirling cavity 1 is easy to process and manufacture, reducing production costs while also making it easier to ensure manufacturing precision. The cylindrical design makes the swirling cavity 1 more balanced during rotation, reduces vibration and wear, and improves the stability and reliability of the equipment's operation.
