Description

Technical Field

[0001] This utility model relates to the field of industrial drying equipment technology, and in particular to a low-noise, vibration-damping adsorption dryer. Background Technology

[0002] Dryers, as indispensable key equipment in industrial production, are widely used in chemical, food, pharmaceutical, and electronics industries. Their core function is to remove moisture or solvents from materials through physical or chemical methods to ensure product quality, extend shelf life, and meet process requirements. With the advancement of industrial technology, the market has placed higher demands on the efficiency, energy consumption, and environmental performance of drying equipment. Adsorption dryers, with their advantages of high efficiency, energy saving, and strong adaptability, have gradually become the preferred solution in fields such as compressed air and gas drying.

[0003] Existing adsorption dryers mostly employ a dual-tower alternating operation structure. The principle is that two adsorption towers filled with adsorbent alternately perform adsorption and regeneration operations: while one tower is in the adsorption state, the other tower desorbs the adsorbed moisture through heating or depressurization, achieving continuous drying. However, the frequent switching and high-speed movement of airflow in the dual-tower structure easily generates significant noise. Although existing technologies reduce noise by adding silencers, soundproof enclosures, or optimizing airflow channels, these measures mostly focus on controlling local noise sources and fail to fundamentally solve the problem of combined noise caused by airflow impact, mechanical vibration, and adsorbent flow.

[0004] Although existing adsorption dryers have reduced noise to some extent through structural optimization and soundproofing design, noise still exists during operation. Long-term operation will further aggravate the noise due to wear and tear on equipment components. The loosening or fluidization process of the adsorbent filling layer can easily cause mechanical vibration, and traditional vibration reduction measures are prone to aging and failure under high-frequency vibration, resulting in various noises increasing with the extension of the usage time. Utility Model Content

[0006] A low-noise, vibration-damping adsorption dryer includes a base, a dryer, and a cover plate. The dryer is mounted on the base, and each end of the base is connected to a column. A top cover is fixedly connected to the top of all the columns. Each column has several circular grooves and threaded holes. Several guide rods are circumferentially connected to one side of the cover plate. The guide rods are slidably connected to the circular grooves of the columns. The cover plate fits snugly against the columns. Fastening screws pass through the cover plate and are threadedly connected to the threaded holes of the columns. Sound insulation cotton is provided on the side of the cover plate facing the dryer, and a transparent observation window is provided in the middle of the front side of the cover plate.

[0007] More preferably, a top plate is further included, the circular groove of the column is widened to form a movable cavity, the top plate is slidably connected in the movable cavity of the column, a reset spring is arranged in the column, one end of the reset spring is connected to the column, and the other end of the reset spring is connected to the top plate, and the guide rod is in extrusion fit with the top plate.

[0008] More preferably, a magnet is connected to the side of the top plate in contact with the guide rod, and the guide rod is in magnetic attraction fit with the magnet.

[0009] More preferably, a sound-absorbing pad is arranged around the side of the column in contact with the cover plate, and the sound-absorbing pad is in extrusion fit with the cover plate.

[0010] More preferably, a handle is connected to the side of the cover plate away from the dryer.

[0011] More preferably, a plurality of heat dissipation holes are formed in the cover plate.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] 1.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example: A low-noise, vibration-damping adsorption dryer, such as... Figures 1-3 As shown, the device includes a base 1, a dryer 2, columns 3, a top cover 4, a cover plate 5, sound insulation cotton 51, an observation window 52, ​​guide rods 6, and fastening screws 7. The dryer 2 is installed on the base 1. Columns 3 are connected to the ends of the base 1. The top of all columns 3 is fixedly connected to the top of the top cover 4. The top cover 4 and the top of the columns 3 are positioned by a mortise and tenon structure and then locked with cross-head screws. The columns 3 have several circular grooves and threaded holes. Several guide rods 6 are connected around one side of the cover plate 5. The guide rods 6 are slidably connected in the circular grooves of the columns 3. The cover plate 5 fits snugly against the columns 3. The fastening screws 7 pass through the threaded holes of the cover plate 5 and are threadedly connected to the columns 3. Sound insulation cotton 51 is provided on the side of the cover plate 5 facing the dryer 2. A transparent observation window 52 is provided in the middle of the front cover plate 5. The observation window 52 is made of PC material and is recessed towards the control panel of the dryer 2, completely fitting the operating interface of the control panel of the dryer 2. The parameters can be adjusted without stopping the machine by directly touching the screen through the window.

[0021] like Figure 3 As shown, it also includes a top plate 9 and a return spring 10. The circular groove of the column 3 is widened to form a movable cavity 8. The top plate 9 is slidably connected to the movable cavity 8 of the column 3. A return spring 10 is provided in the column 3. One end of the return spring 10 is connected to the column 3, and the other end is connected to the top plate 9. The guide rod 6 is pressed and engaged with the top plate 9. The return spring 10 provides a stable rebound force, eliminates the assembly gap between the cover plate 5 and the column 3, and improves the sealing performance.

[0022] like Figure 3 As shown, it also includes a magnet 11. The top plate 9 is connected to the side that contacts the guide rod 6. The guide rod 6 itself is made of magnetic material and magnetically cooperates with the magnet 11. The magnetic structure enables the cover plate 5 to be quickly pre-positioned, reducing assembly alignment time and improving assembly efficiency.

[0023] like Figure 3 As shown, it also includes a sound-absorbing pad 12. The side of the column 3 that contacts the cover plate 5 is surrounded by the sound-absorbing pad 12. The sound-absorbing pad 12 and the cover plate 5 are pressed together. The porous structure absorbs the mechanical vibration of the dryer 2 during operation. The diamond pattern increases the contact area and improves the sound insulation efficiency.

[0024] like Figure 1As shown, it also includes a handle 13, and the handle 13 is connected to the side of the cover plate 5 away from the dryer 2.

[0025] like Figure 1 As shown, the side cover plate 5 has several heat dissipation holes 14, which form a convection air duct to maintain the internal temperature balance of the equipment and prevent overheating.

[0026] During assembly, the workers first place the dryer 2 body stably on the base 1, using the pre-set positioning structure on the base 1 for initial positioning. Then, bolts are used to secure the dryer 2 to the base 1, simultaneously connecting the top cover 4 to the top of the column 3. The workers then hold the handle 13 on the side of the cover plate 5 and lift it up, aligning the guide rod 6 on the back of the cover plate 5 with the circular groove on the side of the column 3. When the guide rod 6 is inserted into the groove, its end magnetically attracts the magnet 11, achieving initial adsorption and positioning. At this point, the cover plate 5 is slowly pushed towards the column 3. As the guide rod 6 slides within the groove, it compresses the magnet 11 and the top plate 9, moving them towards the bottom of the movable cavity 8. The return spring 10 is simultaneously compressed until the contact surfaces of the cover plate 5 and the column 3 are in complete contact. The sound-absorbing cotton 51 inside the cover plate 5 automatically fills the tiny gap between them, and the sound-absorbing pad 12 on the side of the column 3 undergoes elastic deformation due to the pressure from the cover plate 5, forming a double sound-absorbing structure. Workers use fastening screws 7 to pass through the pre-drilled holes in the cover plate 5 and screw them into the threaded holes on the side of the column 3. As the fastening screws 7 are gradually tightened, the rebound force of the return spring 10 and the elastic restoring force of the sound-absorbing pad 12 work together on the cover plate 5, causing the cover plate 5 to continuously apply axial pressure to the screws, ensuring the rigidity of the connection between the cover plate 5 and the column 3. After the front cover plate 5 is fixed, the same steps are repeated to complete the installation of the remaining three side cover plates 5, finally forming a closed outer frame. The observation window 52 of the front cover plate 5 is recessed, ensuring that workers can clearly observe the content displayed on the controller screen and also allowing them to directly touch the control panel buttons through the observation window 52. The heat dissipation holes 14 evenly distributed on the side of the cover plate 5 form a convection air duct, maintaining the internal temperature balance of the equipment while controlling the overall noise level below 55dB.

[0027] When equipment debugging or component replacement is required, the operator first unscrews the fixing screws. The return spring 10 in the movable cavity 8 releases its elastic potential energy, pushing the top plate 9 to reset. The magnet 11 and the end of the guide rod 6 remain magnetically attracted, preventing the cover plate 5 from suddenly falling off. At this time, the elastic restoring force of the sound-absorbing pad 12 creates a gap between the cover plate 5 and the column 3, but the magnetic attraction still ensures that the cover plate 5 is in a suspended state. The operator holds the handle 13 and slowly pulls the cover plate 5 out along the axis of the guide rod 6, causing the guide rod 6 to disengage from the magnet 11. After maintenance, the cover plate 5 can be reset by reversing the assembly process. The magnetic positioning structure ensures that the guide rod 6 can be quickly aligned with the circular groove. The preload of the return spring 10 allows the sound-absorbing pad 12 to re-establish effective vibration damping contact. Finally, the equipment is locked in place by tightening the fastening screw 7 to restore the equipment's sealing state.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
