Description

Technical Field

[0001] This utility model relates to the field of desiccant dryers, specifically a desiccant dryer that is easy to install. Background Technology

[0002] An easy-to-install desiccant dryer is a device used for drying industrial gases. Its core function is to remove moisture from compressed air using adsorbents such as molecular sieves or activated alumina, ensuring the stable operation of downstream gas-using equipment.

[0003] Current easy-to-install desiccant dryers are prone to minor leaks due to fatigue and aging of the sealing rings at pipe flanges and threaded interfaces after long-term use, caused by multiple air pipe connections and the effects of airflow pulsation and mechanical vibration. If these leaks are not detected and repaired in time, they may expand, leading to decreased drying efficiency, abnormally high energy consumption, or even equipment failure or safety accidents caused by gas leakage. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide an easy-to-install desiccant dryer to solve the technical problems of leakage caused by fatigue aging of sealing rings at pipe flanges and threaded interfaces due to vibration stress, poor adaptability of rigid multi-pipe connection structures, low installation and maintenance efficiency, and difficulty in monitoring potential leakage hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install desiccant dryer, comprising a desiccant dryer, the desiccant dryer including a main frame and two adsorption towers, a detection mechanism provided on the back of the main frame, the detection mechanism including a mounting base, the lower front end of the mounting base being welded to the main frame via a connecting frame, a sliding groove being provided on the outer surface of the mounting base, a lead screw being provided in the sliding groove, a motor being provided on the top of the mounting base, the output end of the motor passing through the mounting base and being fixedly connected to the lead screw, the lead screw engaging with a lead screw seat;

[0006] The lead screw seat has a first rotating groove at its front end. A first adjusting rod is rotatably connected to the first rotating groove via a damping shaft. A second rotating groove is formed at the front end of the first adjusting rod. A second adjusting rod is rotatably connected to the second rotating groove via a damping shaft. A mounting screw hole is formed at the front end of the second adjusting rod, and an ultrasonic imager is mounted through the mounting screw hole.

[0007] By adopting the above technical solution, the ultrasonic imager can be automatically moved and detected by a motor-driven lead screw. The multi-angle adjustment rod enhances the flexibility of leak point detection, while the welded structure improves vibration resistance.

[0008] Furthermore, the ultrasonic imager includes an instrument body, and a mounting bolt is provided on the back of the instrument body. The mounting bolt is screwed into a mounting screw hole, and the ultrasonic imager is used to detect leakage points in the connecting pipe.

[0009] By adopting the above technical solution, the modular ultrasonic imager can be quickly assembled and disassembled with bolts, improving maintenance efficiency and ensuring accurate positioning of the detection probe and the leak point.

[0010] Furthermore, two adsorption towers are fixedly connected to the main frame, and the main frame is made of aluminum alloy and has a rectangular structure.

[0011] By adopting the above technical solutions, the aluminum alloy rectangular main frame achieves lightweight and high structural strength, optimizes equipment layout, and reduces installation complexity.

[0012] Furthermore, the outer surface of the adsorption tower is provided with a pressure gauge interface, which is used to install a pressure gauge.

[0013] By adopting the above technical solution, the pressure gauge interface enables real-time monitoring of pipeline pressure and helps to locate the risk of aging of the sealing ring.

[0014] Furthermore, the two adsorption towers are connected by a connecting pipe, and one end of the connecting pipe is connected to an external device.

[0015] By adopting the above technical solutions, the modular connecting pipe design improves the equipment's expandability and adapts to different working conditions.

[0016] Furthermore, a control box is provided at the front end of both adsorption towers.

[0017] By adopting the above technical solutions, the integrated control box enables centralized monitoring and intelligent control of equipment status.

[0018] In summary, the present invention has the following main advantages:

[0019] This invention comprises a monitoring mechanism, a connecting frame, a mounting base, a slide groove, a motor, a lead screw, a lead screw seat, a first rotating groove, a first adjusting rod, a second rotating groove, a second adjusting rod, mounting screw holes, an ultrasonic imager, an instrument body, and mounting bolts. The motor drives the lead screw to control the ultrasonic imager's movement along the slide groove, achieving fully automatic scanning and detection of the adsorption tower's connecting pipes. Combined with the bidirectional damping shaft structure of the first and second adjusting rods, the imager's position can be flexibly adjusted at multiple angles to accurately locate leak points. Simultaneously, the modular design of the ultrasonic imager allows for quick assembly and disassembly via mounting screw holes, and the lightweight aluminum alloy main frame significantly improves maintenance efficiency. The rigid welded structure of the connecting frame and the slide groove effectively suppresses vibration during the detection mechanism's operation. Combined with the real-time pressure monitoring function of the pressure gauge interface, the risk of seal failure is greatly reduced. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] An easy-to-install desiccant dryer, such as Figure 1-4 As shown, the device includes a desiccant 1, which includes a main frame 101 and two adsorption towers. A detection mechanism 2 is provided on the back of the main frame 101. The detection mechanism 2 includes a mounting base 202. The lower front end of the mounting base 202 is welded to the main frame 101 via a connecting frame 201. A sliding groove 203 is provided on the outer surface of the mounting base 202. A lead screw 205 is provided in the sliding groove 203. A motor 204 is provided on the top of the mounting base 202. The output end of the motor 204 passes through the mounting base 202 and is fixedly connected to the lead screw 205. The lead screw 205 is engaged with a lead screw seat 206.

[0027] The lead screw seat 206 has a first rotating groove 207 at its front end. A first adjusting rod 208 is rotatably connected to the first rotating groove 207 via a damping shaft. The front end of the first adjusting rod 208 has a second rotating groove 209. A second adjusting rod 210 is rotatably connected to the second rotating groove 209 via a damping shaft. The front end of the second adjusting rod 210 has a mounting screw hole 211, through which an ultrasonic imager 3 is mounted. The motor 204 drives the lead screw 205 to rotate, causing the lead screw seat 206 to slide along the groove. The lateral movement of groove 203 allows the ultrasonic imager 3 to cover the entire path of the connecting pipe 104 between adsorption towers 102 for detection. The first adjusting rod 208 adjusts the pitch angle through the damping shaft of the first rotating groove 207, and the second adjusting rod 210 adjusts the horizontal direction through the damping shaft of the second rotating groove 209, adapting to complex pipeline routes. The welded structure of the connecting frame 201 and the mounting base 202, combined with the aluminum alloy material of the main frame 101, reduces the vibration amplitude of the detection mechanism 2 to ≤0.1mm, improving detection accuracy.

[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The ultrasonic imager 3 includes an instrument body 301. A mounting bolt 302 is provided on the back of the instrument body 301. The mounting bolt 302 is screwed into the mounting screw hole 211. The ultrasonic imager 3 is used to detect the leakage point of the connecting pipe 104. The ultrasonic imager 3 achieves rapid disassembly and assembly in 10 seconds by screwing the mounting bolt 302 on the back of the instrument body 301 into the mounting screw hole 211. The instrument body 301 is directly fixed to the end of the second adjusting rod 210, eliminating the gap error of the traditional snap-fit ​​structure and ensuring the fit between the probe and the surface of the connecting pipe 104.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Two adsorption towers 102 are fixedly connected to the main frame 101. The main frame 101 is made of aluminum alloy and has a rectangular structure. The use of aluminum alloy in the main frame 101 reduces the overall weight and facilitates installation and handling. The rectangular frame structure is adapted to the layout of the two adsorption towers 102, improving load-bearing stability. The back detection mechanism 2 is integrated with the front control box 105 in separate areas to save space.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4The outer surface of the adsorption tower 102 is provided with a pressure gauge interface 103, which is used to install a pressure gauge. The pressure gauge interface 103 supports the installation of a pressure gauge, provides real-time feedback on the operating status of the adsorption tower 102, and cross-verifies the pressure fluctuation data with the ultrasonic detection results to improve the accuracy of leak identification.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The two adsorption towers 102 are connected by a connecting pipe 104, and one end of the connecting pipe 104 is connected to an external device. The arc-shaped bend of the connecting pipe 104 reduces airflow resistance and improves drying efficiency. The flange and clamp dual-mode interface is compatible with external devices of different pipe diameters.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The two adsorption towers 102 are equipped with a control box 105 at their front end. The control box 105 integrates a touch screen to display operating parameters, supports one-button operation, and has a built-in communication module to realize remote monitoring and parameter adjustment.

[0033] The implementation principle of this embodiment is as follows: First, the motor 204 is started to drive the lead screw 205 to rotate, which drives the lead screw seat 206 to move laterally along the slide groove 203, so that the ultrasonic imager 3 covers the detection path of the connecting pipe 104 between the adsorption towers 102.

[0034] Secondly, the pitch angle and horizontal direction of the ultrasonic imager 3 are manually adjusted by the damping shaft structure of the first adjusting rod 208 and the second adjusting rod 210 to ensure that its probe is accurately aligned with the pipe flange or threaded interface.

[0035] When a leak is detected, the ultrasonic imager 3 transmits the signal to the control box 105. Combined with the real-time pressure data from the pressure gauge interface 103, the leak location is located. The entire process does not require disassembling the main frame 101 or the connecting pipe 104, significantly reducing downtime.

[0036] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
