Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial contactor technology, and in particular to an industrial contactor that automatically adjusts flow rate. Background Technology
[0002] In industrial production, precise flow control plays a crucial role in ensuring production efficiency, product quality, and equipment safety. Industrial contactors, as key components of flow regulation systems, are widely used in numerous industries such as chemical, petroleum, power, and metallurgy.
[0003] Traditional industrial contactors mostly employ relatively simple structural designs, such as ordinary valve-type structures, adjusting flow through manual or simple mechanical devices. These contactors exhibit numerous problems when facing complex and ever-changing industrial conditions. Firstly, they struggle to automatically and accurately adjust flow based on real-time fluid pressure, flow requirements, and other factors. For example, in chemical production, the required flow rate of raw materials changes continuously with the reaction progress; traditional contactors cannot make timely and accurate flow adjustments, affecting reaction efficiency and product quality. Secondly, existing contactors offer limited adjustment methods, lacking flexibility and unable to adapt to various scenarios with different flow ranges and precision requirements.
[0004] Therefore, an industrial contactor that automatically adjusts the flow rate is needed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an industrial contactor that automatically adjusts flow rate.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an industrial contactor for automatically adjusting flow rate, comprising a contactor body, a rear clamp installed on the back of the contactor body, the rear clamp and the contactor body being integral, an adjusting disc installed inside the rear clamp, a connecting pipe connected to the end of the rear clamp, a mounting disc movably connected to the back of the adjusting disc, and flow holes provided on both sides, top and bottom of the front of the mounting disc.
[0007] Preferably, the flow holes on both sides, top and bottom of the front of the mounting plate have different diameters, with the largest flow hole diameter at the top of the front of the mounting plate, and the flow holes are distributed in a ring shape.
[0008] Preferably, the front of the adjustment disk has an elliptical opening, through which a set of flow holes can be exposed at any time.
[0009] Preferably, an arc strip is snapped onto the top of the front of the adjustment disc near the elliptical opening. The arc strip is semi-circular in shape, and a hammer is provided in the middle of the front of the arc strip. A spring is provided at the end of the hammer.
[0010] Preferably, a presser is provided in the middle of the arc strip, the presser is aligned with the hammer, a pneumatic push rod is connected to one side of the presser, and a push bar is engaged at one end of the pneumatic push rod.
[0011] Preferably, the push bar is arc-shaped, and a limiting block is provided at the connection between one end of the arc bar and the push bar, and the push bar and the arc bar are internally slidably connected.
[0012] Preferably, the bottom of the front of the adjustment disc is provided with an insert, and an elastic pull rope is connected between the insert and the end of the push bar.
[0013] Beneficial effects
[0014] The most significant highlight of this automatic flow-regulating industrial contactor lies in its ability to achieve automatic and precise flow regulation. In complex industrial production processes, such as chemical reactions, the reaction process is constantly changing, and the demand for raw material flow also changes accordingly. A pressure sensor installed at the center of the contactor's front side can sensitively capture changes in fluid pressure in real time. When the pressure changes, the pusher will extend or retract the pneumatic push rod according to the pressure magnitude, thereby rotating the regulating disc. In this way, the flow orifice matching the current operating conditions is exposed, achieving rapid and precise flow regulation. This process is fully automated, requiring no frequent manual intervention, greatly improving the timeliness and accuracy of flow regulation, effectively ensuring reaction results, improving product quality, and fundamentally solving the problem that traditional contactors cannot automatically and accurately adjust flow according to real-time operating conditions.
[0015] From a structural design perspective, this contactor exhibits excellent adaptability and stability. The pneumatic push rod employs a corrugated, telescopic structure, working in conjunction with the arc strip, push bar, insert, and elastic pull rope to stably drive the regulating disc rotation under varying pressures, ensuring stable and reliable flow regulation. The pneumatic push rod is configured with four sections, each corresponding to one of the four sets of flow orifices. Each section extends to correspond to a certain degree of rotation of the regulating disc, effectively preventing orifice misalignment caused by slight disc rotation, thus making flow regulation more stable. Furthermore, the components are tightly connected, and corrosion-resistant and high-temperature-resistant materials can be selected, enabling the contactor to operate stably in harsh industrial environments such as high temperature, high pressure, and strong corrosion. This reduces maintenance costs and safety hazards, successfully overcoming the problems of traditional contactors' limited adjustment methods, poor flexibility, and inability to adapt to harsh working conditions.

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:
[0026] Reference Figure 1-5 An industrial contactor for automatically adjusting flow includes a contactor body 1, a rear clamp 2 installed on the back of the contactor body 1, the rear clamp 2 and the contactor body 1 being integral, an adjusting disc 4 installed inside the rear clamp 2, a connecting pipe 3 connected to the end of the rear clamp 2, and a mounting disc 5 movably connected to the back of the adjusting disc 4, with flow holes 15 opened on both sides, top and bottom of the front of the mounting disc 5.
[0027] The design of mounting plate 5 and adjusting plate 4 here is similar to that of existing toothpick box lids, and different holes can be adjusted by rotating them.
[0028] The flow holes 15 on both sides, top and bottom of the front of the mounting plate 5 have different diameters. The flow holes 15 at the top of the front of the mounting plate 5 have the largest diameter and are distributed in a ring.
[0029] In the initial state, the regulating disc 4 will not expose any set of flow holes. Then, the state of the regulating disc 4 will be changed by the water pressure. In the initial state, the regulating disc 4 will rotate counterclockwise, and the smallest set of flow holes 15 should be at the top.
[0030] The front of the regulating plate 4 has an elliptical opening 6. The regulating plate 4 can expose a set of flow holes 15 at a time through the elliptical opening 6. The appropriate flow holes 15 can be opened according to the water pressure.
[0031] An arc-shaped bar 7 is attached to the top of the front of the adjustment disc 4 near the elliptical opening 6. The arc-shaped bar 7 is semi-circular. A hammer 8 is located in the center of the front of the arc-shaped bar 7, and a spring is installed at the end of the hammer 8. A presser 13 is located in the center of the arc-shaped bar 7, and the presser 13 is aligned with the hammer 8. A pneumatic push rod 14 is connected to one side of the presser 13, and a push bar 9 is attached to one end of the pneumatic push rod 14. The pneumatic push rod 14 is corrugated and retractable. When the presser 13 is subjected to external pressure, one side of the pneumatic push rod 14 will pop out. The greater the pressure on the presser 13, the more the pneumatic push rod 14 will pop out. When no pressure is applied, it will spring back. It should be noted that the length of the pneumatic push rod 14 needs to be set according to the actual situation. Figure 4 The image shows the installation positions, without specifying the length.
[0032] The push bar 9 is arc-shaped, and a limiting block 12 is provided at the connection between one end of the arc bar 7 and the push bar 9. The push bar 9 and the arc bar 7 are internally slidably connected. Figure 4 As shown, protrusions are provided at the top and bottom of the connection between the push bar 9 and the arc bar 7, which can be used to achieve limiting by cooperating with the limiting block 12. Figure 4 Arc 7 is the middle section of the entire arc 7.
[0033] An insert 10 is provided at the bottom of the front of the adjustment disc 4, and an elastic pull rope 11 is connected between the insert 10 and the end of the push bar 9.
[0034] like Figure 3 As shown, a circular area is set in the center of the front of the adjustment plate 4. The pressure sensor is installed in this area, and it can also be driven by an automatic motor and cylinder in the future.
[0035] In practical application, the fluid will enter the rear clamp 2 through the pipe 3 and impact the front of the regulating disc 4. When the fluid impacts the hammer 8, the hammer 8 will retract and squeeze the presser 13 inward, causing the presser 13 to flatten. At the same time, the pneumatic push rod 14 on one side will pop out and push the push bar 9 to move. When the push bar 9 moves forward, it will push the insert 10. The insert 10 and the regulating disc 4 are integrated. When the push bar 9 pushes the insert 10, the entire regulating disc 4 will rotate counterclockwise. The greater the pressure on the presser 13, the more the regulating disc 4 will rotate. The more the regulating disc 4 rotates, the larger the orifice 15 will be exposed. When the presser 13 is not under pressure or the pressure decreases, the pneumatic push rod 14 will retract and pull the push bar 9 back. The push bar 9 will also pull the insert 10 through the elastic rope 11, causing the regulating disc 4 to rotate clockwise.
[0036] In practical applications, to prevent the regulating disc 4 from rotating with small amplitude and thus not exposing the flow holes 15 (i.e., the elliptical opening 6 stopping at the gap between two adjacent sets of flow holes 5), the corrugated pneumatic push rod 14 needs to be configured with four sections corresponding to the four sets of flow holes 15. This means the pneumatic push rod 14 can only extend in four states: extending one section causes the regulating disc 4 to rotate 45°, extending two sections causes a 90° rotation, and so on. This eliminates concerns about such situations. An electric drive can also be added later to assist in adjusting the rotation if misalignment is detected. Specific Implementation Example 2:
[0038] Reference Figure 1-5 Considering the complexity of the industrial environment, the contactor body 1 and the rear clamp 2 are made of high-strength, corrosion-resistant stainless steel, such as 316L stainless steel, to ensure long-term stable operation under different fluid media (such as acid, alkali, and salt solutions) and harsh working conditions, extending the service life of the equipment. The regulating disc 4 and the mounting disc are made of engineering plastics with good wear resistance and mechanical strength, such as polyoxymethylene (POM). POM not only meets the wear resistance requirements of rotating parts, but also reduces the inertia of the regulating disc 4 during rotation due to its lighter weight, making its response faster and more accurate. The arc bar 7, push bar 9, and insert 10 can be made of aluminum alloy. Aluminum alloy has the characteristics of low density, high strength, and good corrosion resistance, which can ensure the mechanical performance of the components while reducing the overall weight and facilitating the coordinated movement between the components. The specific size of the flow orifice 15 needs to be accurately calculated according to the actual industrial flow requirements. For example, for flow orifices with small flow rates and fine adjustment, relevant fluid dynamics formulas can be referenced, combined with the required minimum flow rate and allowable pressure loss, to determine the appropriate orifice diameter range. Meanwhile, considering the flow rate variations under different operating conditions, the orifice diameter difference between each flow orifice should be reasonably set to achieve smooth flow rate regulation. The length of the pneumatic push rod 14 is determined not only by the actual installation space but also by its stroke, which is closely related to the rotation angle of the regulating disc 4. Taking a four-section corrugated pneumatic push rod as an example, each section's stroke corresponds to a 45° rotation of the regulating disc 4. Based on the radius of the regulating disc 4 and the relative positional relationship between the elliptical opening 6 and the flow orifice 15, the angle at which the regulating disc 4 should rotate when each section of the pneumatic push rod is ejected needs to be precisely calculated. This determines the specific stroke length of each section of the pneumatic push rod 14, which is set according to the actual situation and will not be detailed here.
[0039] In summary:
[0040] 1. In this device, the fluid will enter the rear clamp 2 through the pipe 3 and impact the front of the regulating disc 4. When the fluid impacts the hammer 8, the hammer 8 will retract and squeeze the presser 13 inward. The presser 13 will flatten, and at the same time, the pneumatic push rod 14 on one side will pop out and push the push bar 9 to move. When the push bar 9 moves forward, it will push the insert 10. The insert 10 and the regulating disc 4 are integrated. When the push bar 9 pushes the insert 10, the entire regulating disc 4 will rotate counterclockwise. The greater the pressure on the presser 13, the more the regulating disc 4 will rotate. The more the regulating disc 4 rotates, the larger the orifice 15 will be exposed. When the presser 13 is not under pressure or the pressure decreases, the pneumatic push rod 14 will retract and pull the push bar 9 back. The push bar 9 will also pull the insert 10 through the elastic pull rope 11, causing the regulating disc 4 to rotate clockwise.
[0041] 2. In practical applications, to prevent the adjusting disc 4 from rotating with small amplitude and thus not exposing the flow holes 15 (i.e., the elliptical opening 6 stopping at the gap between two adjacent sets of flow holes 5), the corrugated pneumatic push rod 14 needs to be set with four sections corresponding to the four sets of flow holes 15. This means the pneumatic push rod 14 can only extend in four states: extending one section causes the adjusting disc 4 to rotate 45°, extending two sections causes a 90° rotation, and so on. This eliminates the risk of this situation occurring. An electric drive can also be added later to assist in adjusting the rotation if misalignment is detected.
