Description
Technical Field
[0001] This utility model relates to the field of zero-gas-consumption desiccant dryer technology, specifically a zero-gas-consumption desiccant dryer for nitrogen generators. Background Technology
[0002] The nitrogen generator-specific zero-air-consumption desiccant dryer is a high-efficiency drying device designed to complement nitrogen generation systems. It achieves deep dehydration of compressed air through zero-air-consumption technology, ensuring the purity and stability of nitrogen production. It utilizes the exhaust waste heat of over 110℃ generated by the air compressor of the nitrogen generator as a regeneration heat source to heat the adsorbent and precipitate moisture, avoiding compressed air loss. The regeneration process does not consume finished compressed air, reducing nitrogen production costs. It is used in industries such as electronics and pharmaceuticals, ensuring that the nitrogen dew point is ≤-40℃.
[0003] The nitrogen generator-specific zero-air-consumption desiccant dryer consists of a dual adsorption tower, a controller, and working components connected to the dual adsorption towers. During operation, the two adsorption towers filled with molecular sieves work alternately. One tower adsorbs moisture from the compressed air, while the other tower regenerates and desorbs moisture through waste heat, achieving continuous drying. However, existing nitrogen generator-specific zero-air-consumption desiccant dryers are directly installed in the factory for use. Due to the complex internal conditions of the factory and the protruding operation buttons on the controller, workers may accidentally bump into the buttons while transporting materials, causing changes in the parameters set inside the controller and affecting the normal operation of the zero-air-consumption desiccant dryer. Utility Model Content
[0004] The purpose of this utility model is to provide a zero-gas-consumption desiccant dryer specifically for nitrogen generators, in order to solve the problem mentioned in the background art that the operation buttons on the controller of the existing zero-gas-consumption desiccant dryer specifically for nitrogen generators are raised, which makes it easy for workers to accidentally touch the buttons during the transportation of materials.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a zero-gas-consumption adsorption dryer for nitrogen generators, comprising an adsorption tower body and a control box, wherein conduits are connected to both sides of the adsorption tower body, the outer side of the adsorption tower body is welded to a support base, and a control box is provided on the upper side of the support base;
[0006] An installation base is welded to the inner side of the adsorption tower body. Guide rails are symmetrically welded to the upper side of the installation base. The tops of both guide rails are welded to the protective frame. An internal threaded adjusting column is welded to one side of the control box. The internal threaded adjusting column is threadedly connected to a threaded adjusting rod. A transmission gear and two abutment discs are welded to the outer side of the threaded adjusting rod. The outer side of the transmission gear meshes with the drive gear. The bottom of the installation base is connected to the drive motor through locking bolts. The top of the drive motor is connected to the drive gear through a coupling.
[0007] Preferably, both guide rails have dovetail grooves inside, and dovetail blocks are inserted into both dovetail grooves.
[0008] Preferably, the two dovetail blocks are welded to the control box on adjacent sides, and the bottom of the threaded adjusting rod is inserted through the slot inside the mounting base.
[0009] Preferably, the two abutting discs abut on adjacent sides and abut against the mounting base, and rotatable steel balls are embedded inside the two abutting discs.
[0010] Preferably, a plug-in socket is welded to the upper side of the mounting base, and a base is welded to the bottom of the control box, with the base being plugged into the plug-in socket.
[0011] Preferably, an air chamber is welded inside the connector, a buffer plate is inserted into the air chamber, and a return spring is installed inside the air chamber.
[0012] Preferably, both the plug and the mounting base are provided with an inflation port, and an inflation tube is connected to the bottom of the inflation port, with a control valve installed inside the inflation tube.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This zero-gas-consumption desiccant dryer for nitrogen generators can raise the height of the control box when idle and is equipped with a protective frame to protect the control box, which is staggered from the height of the human body, effectively preventing the buttons on the outside of the control box from being accidentally touched. In addition, it is equipped with a base and plug-in to buffer and guide the descent of the control box, making the control box more stable during movement. This solves the problem that the operation buttons on the controller of the existing zero-gas-consumption desiccant dryer for nitrogen generators are protruding, which makes it easy for workers to accidentally touch the buttons when transporting materials.
[0014] 1. This zero-gas-consumption desiccant dryer for nitrogen generators, to prevent accidental activation of the buttons on the outside of the control box, after the control box is set up, starts the output end of the drive motor, which drives the drive gear to rotate through the coupling and mesh with the transmission gear. This causes the threaded adjusting rod welded in the middle of the transmission gear to rotate and interact with the internal threaded adjusting column, thereby moving the control box upward along the guide rail and sending the control box into the protective frame welded to the top of the guide rail for protection. This zero-gas-consumption desiccant dryer for nitrogen generators can increase the height of the control box when not in use and is equipped with a protective frame to protect the control box, which is staggered from the height of the human body, effectively preventing accidental activation of the buttons on the outside of the control box.
[0015] 2. This zero-gas-consumption desiccant dryer for nitrogen generators, to prevent the control box from colliding with the mounting base during descent and causing internal mounting components to loosen due to vibration, features a design where the base at the bottom of the control box first engages with the plug-in connector and contacts the buffer plate as the control box moves downwards. This pushes the buffer plate to compress the gas inside the inflation chamber. Simultaneously, the return spring inside the inflation chamber, under compression, generates elasticity and pushes the buffer plate, thus buffering the base and the control box on top of the base. This zero-gas-consumption desiccant dryer for nitrogen generators is equipped with a base and plug-in connector to buffer and guide the descent of the control box, making the control box more stable during movement.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-3This utility model provides a technical solution: a zero-gas-consumption adsorption dryer for nitrogen generators, including an adsorption tower body 1 and a control box 3. The adsorption tower body 1 is connected to two sides by conduits 101. The outer side of the adsorption tower body 1 is welded to a support base 2. The control box 3 is provided on the upper side of the support base 2.
[0024] An installation base 4 is welded to the inner side of the adsorption tower body 1. Guide rails 401 are symmetrically welded to the upper side of the installation base 4. The tops of the two guide rails 401 are welded to the protective frame 404. An internal threaded adjusting column 403 is welded to one side of the control box 3. The internal threaded adjusting column 403 is threadedly connected to the threaded adjusting rod 4031. A transmission gear 4033 and two abutment plates 4032 are welded to the outer side of the threaded adjusting rod 4031. The outer side of the transmission gear 4033 meshes with the drive gear 4034. The bottom of the installation base 4 is connected to the drive motor 4035 by locking bolts. The top of the drive motor 4035 is connected to the drive gear 4034 by a coupling.
[0025] Both guide rails 401 have dovetail grooves 4011 inside, and dovetail blocks 402 are inserted into both dovetail grooves 4011. The adjacent sides of the two dovetail blocks 402 are welded to the control box 3. The bottom of the threaded adjusting rod 4031 is inserted through the groove inside the mounting base 4. The adjacent sides of the two abutting plates 4032 are abutted to the mounting base 4, and rotatable steel balls are embedded inside the two abutting plates 4032.
[0026] In practice, to prevent accidental activation of the buttons on the outside of control box 3, after control box 3 is set up, drive motor 4035 is started. The output end of drive motor 4035 drives drive gear 4034 to rotate via coupling. When drive gear 4034 rotates, its outer side meshes with transmission gear 4033, causing the threaded adjusting rod 4031 welded in the middle of transmission gear 4033 to start rotating under the action of abutment plate 4032 and mounting base 4. When threaded adjusting rod 4031 rotates, it engages with the control... The internal threaded adjusting column 403 welded on one side of the control box 3 acts as a thread, thereby driving the dovetail blocks 402 welded on both sides of the control box 3 to move upward along the dovetail groove 4011 inside the guide rail 401, sending the control box 3 into the protective frame 404 welded on the top of the guide rail 401 for protection. This nitrogen generator-specific zero-gas-consumption desiccant can raise the height of the control box 3 when idle and is equipped with a protective frame 404 to protect the control box 3, which is staggered from the height of the human body, effectively preventing the buttons on the outside of the control box 3 from being accidentally touched.
[0027] See Figures 3-5It is known that a plug-in seat 501 is welded to the upper side of the mounting base 4, and a base 5 is welded to the bottom of the control box 3. The base 5 is plugged into the plug-in seat 501. An inflation chamber 503 is welded inside the plug-in seat 501. A buffer plate 502 is inserted into the inflation chamber 503. A return spring 504 is installed inside the inflation chamber 503. Both the plug-in seat 501 and the mounting base 4 are provided with inflation ports. An inflation pipe 505 is connected to the bottom of the inflation port. A control valve 506 is installed inside the inflation pipe 505.
[0028] In practice, to prevent the control box 3 from colliding with the mounting base 4 during descent, which could cause the internal mounting components to loosen due to vibration, the base 5 at the bottom of the control box 3 will first connect with the plug-in base 501 when the control box 3 moves downward. At this time, the buffer plate 502 on the inner side of the plug-in base 501 will first contact the inner wall of the base 5. The buffer plate 502 moves downward under the push of the base 5, compressing the gas inside the inflation chamber 503. At the same time, the return spring 504 inside the inflation chamber 503 will generate elasticity under the compression, pushing the buffer plate 502, thereby achieving buffering of the base 5 and the control box 3 on the upper side of the base 5. When the gas pressure in the inflation chamber 503 is insufficient, the control valve 506 at the inflation pipe 505 can be opened to supplement the gas into the inflation chamber 503 through the inflation pipe 505 and the inflation port. This nitrogen generator-specific zero-gas-consumption desiccant is equipped with a base 5 and a plug-in base 501 to buffer and guide the descent of the control box 3, making the control box 3 more stable during movement.
[0029] In summary, when using the zero-gas-consumption desiccant specifically designed for nitrogen generators, the output of the start-up drive motor 4035 drives the drive gear 4034 to rotate via a coupling, meshing with the transmission gear 4033. This causes the threaded adjusting rod 4031 welded in the middle of the transmission gear 4033 to rotate and interact with the internal threaded adjusting column 403, thereby moving the control box 3 downwards along the guide rail 401. The control box 3 is then completely removed from the protective frame 404. At this point, the operator can operate the adsorption tower body 1 via the control buttons on the outside of the control box 3, and process the gas used by the nitrogen generator through the conduit 101. The support base 2 is used to support the installation of the adsorption tower body 1. Contents not described in detail in this specification are prior art known to those skilled in the art.
[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
