Description

Technical Field

[0001] This application relates to the field of desiccant technology, and more particularly to a modular adsorption desiccant. Background Technology

[0002] A desiccant dryer is a device that uses an adsorbent to selectively adsorb water vapor from compressed air, thereby dehydrating and drying the compressed air.

[0003] A desiccant dryer is designed in the related technology, including a body with a drying chamber inside. An air inlet is provided at one end of the body and an air outlet is provided at the other end. Both the air inlet and the air outlet are connected to the drying chamber. A drying filter is provided inside the drying chamber. Compressed air is introduced into the drying chamber through the air inlet. The compressed air passes through the drying filter to remove impurities, water vapor and oil from the compressed air, and is then discharged through the air outlet.

[0004] Regarding the aforementioned technologies, the following problems exist: the drying filter is located inside the drying chamber. After prolonged operation, the drying filter will become saturated with moisture, resulting in a decrease in the drying filter's ability to absorb water vapor. This, in turn, reduces the drying efficiency of the desiccant dryer. Furthermore, if the desiccant dryer operates for an extended period, a single drying filter cannot effectively absorb water vapor. Therefore, improvements are needed. Utility Model Content

[0005] To address the issue that existing desiccant dryers use a single drying filter, which leads to reduced drying efficiency and ineffective moisture absorption over long-term use, this application provides a modular adsorption desiccant dryer.

[0006] The modular adsorption-type desiccant dryer provided in this application adopts the following technical solution: A modular adsorption-type desiccant includes a body with a drying chamber inside. An air inlet is located on one side of the body, and an air outlet is located on the other side. Both the air inlet and outlet are connected to the drying chamber. An opening / closing port is formed through one side wall of the drying chamber, and an opening / closing door is slidably connected to the outer wall of the opening / closing port. Several partitions are arranged inside the drying chamber, and a desiccant module is arranged between adjacent partitions. Each partition has a through-hole along its thickness for compressed air to pass through.

[0007] By adopting the above technical solution, this application uses several desiccant modules. On the one hand, it can quickly replace desiccant modules that have been working for a long time and whose drying efficiency has decreased. On the other hand, it can arrange multiple desiccant modules based on the working time of the desiccant dryer, so that the desiccant dryer can maintain high drying efficiency over a long working cycle.

[0008] Preferably, clamping plates are provided on both the upper and lower sides between two adjacent partition plates, and sliding guide posts are provided on the opposite sides of the two clamping plates. The sliding guide posts are slidably connected to the inner wall of the drying chamber. An elastic element is sleeved on the periphery of the sliding guide post. The two ends of the elastic element abut against the clamping plate and the inner wall of the drying chamber. The elastic element makes the surface of the clamping plate flush with the inner wall adjacent to the communication opening when no force is applied.

[0009] By adopting the above technical solution, the clamping plate can effectively fix the desiccant module. At the same time, due to the presence of the elastic element, the desiccant dryer of this application can adapt to the installation and application of desiccant modules of different lengths, thereby improving the flexibility and applicability of the desiccant dryer of this application.

[0010] Preferably, a positioning post is provided between each of the two adjacent partition plates, the positioning post is connected to the inner wall of the drying chamber, and the side wall of the desiccant module is provided with a positioning hole for the positioning post to be inserted.

[0011] By adopting the above technical solution, setting positioning columns can effectively improve the stability of the desiccant module's working state, allowing the desiccant module to be relatively fixed in one place, ensuring effective drying.

[0012] Preferably, a corrugated pipe is provided inside the drying chamber, the corrugated pipe is connected to the air outlet, and a flow guide is provided at the end of the corrugated pipe away from the air outlet. The width of the flow guide is adapted to the width of the connecting port. A sliding rod is provided on the side wall of the flow guide facing the corrugated pipe. The sliding rod passes through the inner wall of the drying chamber and is slidably connected to the machine body.

[0013] By adopting the above technical solution, based on the number of desiccant modules, the position of the guide hood is adjusted by sliding rod so that the guide hood can enter the communication port of the partition plate and abut against the last desiccant module, thereby ensuring that the compressed air can stably enter the bellows after drying and reducing the probability of compressed air expansion.

[0014] Preferably, the sliding rod has a threaded section on its peripheral wall, and a fixed plate is threadedly connected to the peripheral wall of the sliding rod outside the machine body. The fixed plate is provided with a plurality of fasteners for connecting the fixed plate to the machine body.

[0015] By adopting the above technical solution and setting the threaded section and the fixed plate, the stability of the position of the flow hood after adjustment can be maintained, thereby reducing the probability of compressed air leakage.

[0016] Preferably, the inner wall of the drainage hood is provided with a drainage surface, which is inclined toward the opening direction of the corrugated pipe.

[0017] By adopting the above technical solution, the compressed air, after being dried by the desiccant module, can be concentrated and enter the bellows, and then discharged through the air outlet, thereby improving the operating efficiency of the desiccant dryer of this application.

[0018] Preferably, a sealing ring groove is provided around the opening, a sealing ring plate is slidably connected in the sealing ring groove, and an insertion ring groove is provided on the side of the opening and closing door panel facing the sealing ring groove for the sealing ring plate to enter.

[0019] By adopting the above technical solution, the sealing between the door panel and the machine body can be improved when the door panel is in the closed state, the probability of compressed air leakage can be reduced, and the air pressure inside the desiccant can be kept stable.

[0020] Preferably, the top of the body is slidably connected with a plug pin, and the bottom surface of the opening and closing door panel is provided with a plug hole for the plug pin to be inserted.

[0021] By adopting the above technical solution, the insertion pin can keep the door panel stable when it is in the open state, so as to facilitate the installation, disassembly or replacement of the desiccant module in the drying chamber.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application employs several desiccant modules, which on the one hand allows for quick replacement of desiccant modules that have been working for a long time and whose drying efficiency has decreased, and on the other hand allows for the arrangement of multiple desiccant modules based on the working time of the desiccant dryer, enabling the desiccant dryer to maintain high drying efficiency over a longer working cycle. 2. The clamping plate enables effective fixation of the desiccant module. At the same time, due to the presence of the elastic element, the desiccant dryer of this application can adapt to the installation and application of desiccant modules of different lengths, thereby improving the flexibility and applicability of the desiccant dryer of this application.
