Description

Technical Field

[0001] This application relates to the field of gas treatment technology, and more particularly to a dryer, compressed air system and vehicle. Background Technology

[0002] Air compressors in industrial applications are usually equipped with dryers to remove moisture from compressed air and ensure that the quality of compressed air meets process requirements.

[0003] Compressed air supplied by air compressors often contains oil mist. If not effectively treated, this oil mist will accumulate over time, gradually narrowing congested passages in the air system, degrading the performance of elastic seals, and, more seriously, contaminating desiccants (such as molecular sieves), causing "poisoning" of the molecular sieves and significantly shortening their lifespan. Although some dryers are equipped with oil mist filters, these only intercept oil mist and are ineffective against oil droplets that have condensed, often requiring the use of absorbent cotton pads. This method not only consumes materials and increases operating costs, but also requires frequent replacement and maintenance of the absorbent cotton pads, affecting the stable operation and maintenance efficiency of the system.

DETAILED DESCRIPTION

[0056] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative effort fall within the protection scope of the present application.

[0057] The present application provides a dryer, please refer to Figures 1 to 3 , Figures 1 to 5 The structural schematic diagram of the dryer provided by the embodiments of the present application.

[0058] The dryer 100 comprises a shell 1, a filter plate 2, and a receiving member 3.

[0059] The shell 1 is provided with an air inlet 11, an air outlet 12, and a filter flow channel 13 connecting the two, the shell 1 plays a role of encapsulation and guidance, ensuring that the gas can only flow along the preset path, i.e. the filter flow channel 13, so as to pass through the filter link arranged therein, the air inlet 11 is responsible for introducing the gas to be treated, and the air outlet 12 is used for releasing the clean gas which has been purified.

[0060] The filter plate 2 is positioned at a key position inside the filter flow channel 13, and the core task of the filter plate 2 is to purify the gas flowing through, focusing on removing the oil mist carried therein, ensuring that the oil mist will not continue to advance with the airflow, but will be intercepted on the surface of the plate and gradually form oil droplets. It can be understood that the filter plate 2 can also be used to remove impurities (fixed particles) carried in the gas.

[0061] The receiving member 3 is placed in the shell 1 and located below the filter plate 2 (based on the direction of gravity), and a special receiving groove 31 is arranged in the receiving member 3 (see Figure 4), receives and collects the oil droplets gathered on the filter plate 2 due to gravity, prevents the oil droplets from being brought into the airflow again, effectively separates the oil droplets from the gas, avoids the recirculation of oil stains, and guarantees the quality of the purified gas.

[0062] In the technical solution of the present application, the oil droplets intercepted by the filter plate 2 are received and collected by the receiving groove 31 of the receiving member 3, ensuring that the oil droplets are effectively gathered and stored, eliminating the dependence on oil absorption cotton sheets, achieving the purification of oil mist in the gas, reducing operating costs and maintenance workload, and improving operating efficiency and economy.

[0063] In some embodiments, specifically Figure 2 , the filter plate 2 has an upper plate surface and a lower plate surface arranged oppositely in the direction of gravity, the lower plate surface of the filter plate 2 is arranged obliquely to have a highest end and a lowest end in the direction of gravity, and the receiving groove 31 is at least partially below the lowest end of the lower plate surface. In these embodiments, the lower plate surface is in an inclined state, ensuring a clear highest end and lowest end, aiming to facilitate the oil droplets condensed on the filter plate 2 to naturally slide and collect to the lowest end by gravity, and the at least part of the receiving groove 31 is just below the lowest end of the lower plate surface of the filter plate 2, ensuring that all the oil droplets sliding down the lower plate surface can be received by the receiving groove 31, avoiding omission and maximizing the collection effect. In this way, the gravity is used as the driving force, and no additional power device is needed to achieve effective guidance and centralized collection of oil droplets, which greatly simplifies the structural complexity and energy consumption of the entire dryer 100 on the one hand, and significantly enhances the reliability and maintenance convenience of the system on the other hand, reducing operating costs. At the same time, centralized collection also provides convenient conditions for subsequent oil management, such as regular discharge or recycling, further promoting resource recycling and environmental protection.

[0064] It can be understood that an excessively small inclination angle of the lower plate surface may result in an excessively slow sliding speed of the oil droplets on the lower plate surface, or even an ineffective movement due to surface tension or adhesion; an excessively large inclination angle may cause an excessively fast sliding speed of the oil droplets, increasing the risk of oil droplet splashing, and may also intensify airflow disturbance, interfering with the filtration efficiency, and an excessively large inclination angle is also not conducive to maintaining the structural stability of the filter plate 2, bringing about an increase in manufacturing difficulty, and may also make the sliding path of the oil droplets unpredictable.

[0065] In some embodiments, the inclination angle of the lower plate surface is greater than or equal to 1° and less than or equal to 5°. In these embodiments, the inclination angle of the lower plate surface is limited to between 1° and 5°, balancing the sliding speed of the oil droplets and the adhesion of the plate surface, ensuring smooth sliding of the oil droplets without losing speed, while reducing airflow disturbance, maintaining smooth gas flow, and facilitating structural stability and easy processing. Moderate inclination promotes the alignment accuracy of the receiving groove 31 and improves the oil droplet collection efficiency.

[0066] In some embodiments, the inclination angle of the lower plate surface is greater than or equal to 2° and less than or equal to 3°. In these embodiments, the inclination angle of the lower plate surface of the filter plate 2 is controlled to be between 2° and 3°, taking into full consideration the oil droplet sliding efficiency and system stability, which can not only accelerate the natural sliding of oil droplets along the plate surface and avoid stagnation, but also ensure smooth airflow and guarantee filtering efficiency, while simplifying the structural design and assembly process and improving the accuracy of oil droplet collection and overall operation efficiency.

[0067] In some embodiments, specifically as shown in Figure 2 , the upper plate surface is horizontally arranged so that the thickness of the filter plate 2 gradually increases in the direction from the highest end of the lower plate surface to the lowest end of the lower plate surface. In these embodiments, the horizontally arranged upper plate surface ensures that oil droplets can be uniformly distributed on the filter plate 2, and as the oil droplets accumulate, the gradually increasing thickness of the filter plate 2 helps the oil droplets to gather to a certain volume before they start to slide down, avoiding the decrease in collection efficiency caused by premature dripping.

[0068] In some embodiments, specifically as shown in Figure 2 , the housing 1 further has an inner circumferential side surface surrounding the filter plate 2, and the inner circumferential side surface is sealingly connected with the outer periphery of the filter plate 2, and the receiving groove 31 is annular (in combination with Figure 4 ) and extends along the circumference of the inner circumferential side surface. In these embodiments, the outer periphery of the filter plate 2 is sealingly connected with the inner circumferential side surface to ensure sealing, and the annular receiving groove 31 extends along the circumference of the inner circumferential side surface to comprehensively receive oil droplets dripping from the outer periphery of the filter plate 2, reducing omission and improving collection efficiency. In addition, the receiving member 3 forms a hollow structure, which not only ensures efficient collection of oil droplets, but also plays the role of a gas passage to ensure that gas can pass freely, avoiding hindering the air flow of the overall system.

[0069] In some embodiments, specifically as shown in Figure 2 , the housing 1 has an arc-shaped top surface 14 arranged opposite the filter plate 2, and the receiving groove 31 is further used to receive water droplets formed on the arc-shaped top surface 14. In these embodiments, the design of the arc-shaped top surface 14 helps the formation and collection of condensed water, and these water droplets are eventually collected by the receiving groove 31 to improve the dryness of the gas.

[0070] In some embodiments, the inner circumferential side surface is connected to the outer periphery of the arc-shaped top surface 14. In these embodiments, the water droplets formed on the arc-shaped top surface 14 can flow along the inner circumferential side surface into the receiving groove 31, guiding the orderly flow of water droplets so that the water droplets quickly converge into the receiving groove 31, avoiding splashing and improving the collection efficiency of water droplets.

[0071] In some embodiments, specifically as shown in Figure 1 and Figure 2The dryer 100 further comprises a fixing plate 4, the outer periphery of the fixing plate 4 is connected with the inner circumferential side of the shell 1, the fixing plate 4 is arranged in the filter flow channel 13, the fixing plate 4 is provided with the first air permeable hole, and the fixing plate 4 and the receiving piece 3 clamp the filter plate 2. In these embodiments, the first air permeable hole allows the airflow to pass through, the fixing plate 4 clamps the filter plate 2 together with the receiving piece 3, the structural stability of the filter plate 2 is strengthened, the risk of displacement due to vibration or back blowing of the dryer 100 is avoided, and the overall performance and reliability of the dryer 100 are improved.

[0072] It can be understood that a plurality of first air permeable holes can be arranged, and the airflow in the filter flow channel 13 can be controlled through the precise design of the first air permeable hole. The size and distribution of the aperture of the first air permeable hole affect the airflow speed, so as to ensure that the airflow passes through the filter plate 2 smoothly and sufficiently, and the filtering effect is optimized.

[0073] In some embodiments, in combination with reference to Figure 4 The fixing plate 4 comprises a first plate body 41 and a first ring body 42, the first plate body 41 is provided with the first air permeable hole, and the first ring body 42 is connected to the outer periphery of the first plate body 41 and clamps the filter plate 2 together with the receiving piece 3. In these embodiments, the first plate body 41 is provided with the first air permeable hole, the first ring body 42 increases the thickness of the periphery of the fixing plate 4, the rigidity and stability of the entire structure are improved through the connection with the inner circumferential side of the shell 1, external impact and internal pressure changes are effectively resisted, and the reliability of the structure is improved. Specifically, the first ring body 42 is provided with a first notch 421 to ensure the circulation of the gas.

[0074] In some embodiments, specifically as shown in Figure 2 and Figure 3 The dryer 100 further comprises a liquid discharge port 110 and an on-off device 5. The liquid discharge port 110 is arranged in the shell 1 and is communicated with the receiving groove 31 through the discharge channel 15. The on-off device 5 is used to close or open the discharge channel 15. In these embodiments, the liquid discharge port 110 is communicated with the receiving groove 31 through the discharge channel 15, which facilitates the periodic or on-demand discharge of the accumulated oil droplets in the receiving groove 31, simplifies the maintenance process, the on-off device 5 controls the opening and closing of the discharge channel 15, prevents unplanned leakage, ensures that oil discharge is only started under specified conditions, and avoids accidental overflow affecting equipment operation or the surrounding environment.

[0075] It can be understood that the on-off device 5 can adopt mechanical or electronic control means to realize automatic or manual operation modes. For example, the on-off device 5 is an electromagnetic valve to realize the automatic mode, and the on-off device 5 is a plug which can be manually inserted and pulled out.

[0076] In some embodiments, specifically as shown in Figure 2The on-off device 5 comprises a valve core 51 and a first elastic member 52 arranged in the discharge channel 15. The first elastic member 52 is arranged between the valve core 51 and the shell 1. The first elastic member 52 is used to overcome the gas pressure in the filtering flow channel 13 to drive the valve core 51 to close the discharge channel 15. In these embodiments, the first elastic member 52 (such as a spring) is arranged between the valve core 51 and the shell 1 to give the valve core 51 sufficient restoring force to resist the pressure of the gas in the filtering flow channel 13. When the oil discharge is completed, the first elastic member 52 causes the valve core 51 to tightly adhere to the inner side of the shell 1 to ensure the sealing. The valve core 51 prevents the oil from flowing back to the receiving groove 31 in the normal state, and can quickly respond to open the channel to smoothly discharge the oil when the oil needs to be discharged. It can be understood that, as the gas continuously enters, the gas pressure in the shell 1 gradually rises. The gas is sufficient to overcome the resistance of the spring to cause the valve core 51 to open, and the oil-water mixture can be smoothly discharged. At the same time, a certain amount of gas is released. With the discharge of the oil-water and gas, the gas pressure decreases until it is lower than the pre-tightening force of the first elastic member 52. The valve core 51 re-closes the discharge channel 15 to cut off the discharge path, and prepares for the next cycle of air charging and pressure accumulation to realize the automatic periodic discharge of the oil. The valve core 51 and the first elastic member 52 form a mechanical one-way valve, which is simple and reliable in structure and low in operation cost.

[0077] In some embodiments, as shown in Figure 2 The dryer 100 further comprises a liquid storage tank 16 arranged in the shell 1. The liquid storage tank 16 is in communication with the receiving groove 31 to store the oil droplets flowing from the receiving groove 31. The bottom of the liquid storage tank 16 is provided with a discharge channel 15. In these embodiments, the liquid storage tank 16 is connected with the receiving groove 31 to collect and temporarily store the oil droplets flowing from the receiving groove 31. The bottom of the liquid storage tank 16 is provided with a discharge channel 15, and the oil can be directly discharged through the discharge channel 15. The arrangement of the liquid storage tank 16 can concentrate the treatment of the oil and facilitate the direct inspection of the oil accumulation through the liquid storage tank 16, thereby improving the convenience and overall efficiency of the oil treatment.

[0078] In some embodiments, as shown in Figure 1 and Figure 3The dryer 100 further comprises a drying member 6, which is arranged in the filtering flow channel 13 and between the filtering plate 2 and the air outlet 12, and is used to filter the moisture in the gas flowing therethrough. In these embodiments, the drying member 6 is installed in the filtering flow channel 13 and arranged between the filtering plate 2 and the air outlet 12, so that the gas filtered by the filtering plate 2 is subjected to the drying treatment of the drying member 6, the drying member 6 absorbs and removes the moisture carried in the gas, keeps the gas dry, prevents the downstream equipment from being damp or dewing, and improves the quality of the filtered gas.

[0079] It can be understood that the drying member 6 can be silica gel, activated alumina, calcium chloride or mineral desiccant, etc. In some embodiments, the drying member 6 is a molecular sieve. The pore size of the molecular sieve can be finely controlled, which can better absorb moisture. The molecular sieve has a very high internal surface area and can absorb a large amount of moisture. Through heating, the molecular sieve can release the absorbed moisture, so as to realize reuse and have renewability. The molecular sieve can work in a wide temperature range and can adapt to different drying processes. In this way, the drying efficiency and drying quality can be improved, and energy consumption can be reduced.

[0080] In some embodiments, as shown in Figure 1 and Figure 3 , the dryer 100 further comprises a pressing plate 7 and a supporting plate 8. The pressing plate 7 (in combination with Figure 4 ) is arranged in the filtering flow channel 13 and has a second gas-permeable hole. The supporting plate 8 (in combination with Figure 5 ) is arranged in the filtering flow channel 13 and has a third gas-permeable hole. The pressing plate 7 and the supporting plate 8 clamp the drying member 6. In these embodiments, the drying member 6 (such as a molecular sieve) is fixed by the pressing plate 7 and the supporting plate 8, so as to ensure the stable position of the drying member 6 (such as a molecular sieve) in the gas flow and prevent the drying member 6 (such as a molecular sieve) from moving or being damaged due to the impact of the gas flow. It can be understood that the pressing plate 7 with the second gas-permeable hole and the supporting plate 8 with the third gas-permeable hole can also cooperatively guide the gas flow, so that the gas uniformly passes through the drying member 6, moisture is fully absorbed, and the drying effect is improved. Specifically, the supporting plate 8 comprises a second plate body 81 and a second ring body 82 connected to the outer periphery of the second plate body 81. The second gas-permeable hole is arranged on the second plate body 81, so as to ensure the smoothness of the gas flow and the balance of the drying process. The second ring body 82 ensures the strength of the entire structure. More specifically, the second ring body 82 is provided with a third gap 821, so as to ensure the circulation of the gas.

[0081] In some embodiments, as shown in Figure 2, the housing 1 is provided with a protrusion 17, the protrusion 17 is located on the side of the pressing plate 7 away from the drying element 6, and the dryer 100 further comprises a second elastic member 9 arranged between the protrusion 17 and the pressing plate 7. In these embodiments, the second elastic member 9 is installed between the protrusion 17 and the pressing plate 7, providing additional pressure and enhancing the fixing effect of the drying element 6 (such as molecular sieve), while also helping to absorb the impact caused by gas flow fluctuations, thereby maintaining the ideal pressing state of the pressing plate 7 on the drying element 6 and prolonging the service life by buffering external impact and vibration.

[0082] In some embodiments, specifically as shown in Figure 1 , Figure 3 and Figure 5 , the dryer 100 further comprises a buffer member 10 arranged between the support plate 8 and the drying element 6. In these embodiments, the buffer member 10 can absorb the impact caused by gas flow or mechanical vibration, and also has an isolation protection effect, avoiding the risk of particle shedding of the drying element 6 (such as molecular sieve). Specifically, the buffer member 10 is buffer cotton.

[0083] In some embodiments, specifically as shown in Figure 1 and Figure 3 , the filter flow channel 13 comprises a plurality of installation cavities 131 (two installation cavities 131 are shown in Figure 1 ) arranged in the housing 1 and separated from each other, an air inlet channel 132, and an air outlet channel 133. One end of the air inlet channel 132 is in communication with the plurality of installation cavities 131, respectively, and the other end of the air inlet channel 132 is in communication with the air inlet 11. One end of the air outlet channel 133 is in communication with the plurality of installation cavities 131, respectively, and the other end of the air outlet channel 133 is in communication with the air outlet 12. Each installation cavity 131 is provided with a filter plate 2, a receiving member 3, and a drying element 6. In these embodiments, a plurality of installation cavities 131 are constructed in the housing 1, which are separated from each other, and each installation cavity 131 is provided with a filter plate 2, a receiving member 3, and a drying element 6, forming independent filtering and drying units, improving the processing efficiency and flexibility. One end of the air inlet channel 132 is in communication with each installation cavity 131, and the other end is directly connected to the air inlet 11. The air outlet channel 133 collects the processed gas from each installation cavity 131, and finally converges to the air outlet 12, ensuring the orderly flow and efficient processing of the gas (straight arrows in Figure 1 indicate the direction of gas flow). It can be understood that other structures can also be arranged in each installation cavity 131 as needed, such as the fixing plate 4, the pressing plate 7, the support plate 8, the second elastic member 9, or the buffer member 10 in some embodiments (the structures installed in one of the installation cavities 131 are shown in an explosion in Figure 3 ).

[0084] In some embodiments, specifically as shown in Figure 1 and Figure 3The shell 1 comprises a shell body 18 and a cover plate 19 (in combination with Figure 4 and Figure 5 The shell body 18 is provided with a plurality of installation cavities 131, each of which is open at at least one of the upper end and the lower end in the gravity direction, and the cover plate 19 is separately provided with the shell body 18 and used to cover the opening. In these embodiments, the shell body 18 is internally provided with a plurality of installation cavities 131, each of which is open at the upper end or the lower end in the gravity direction, aiming to facilitate maintenance and material access. The cover plate 19 is separately made with the shell body 18 and used to cover the above-mentioned opening, ensuring the closure and integrity of the internal environment. The separate design makes the cover plate 19 easy to disassemble, which can quickly respond to regular cleaning, component inspection or emergency repair, reduce the difficulty of production and simplify the maintenance process. Specifically, the upper end and the lower end of each installation cavity 131 are open, allowing workers to install and maintain the components in the installation cavity 131 nearby, simplifying the installation and maintenance process.
