Description

Technical Field

[0001] The invention relates to the technical field of air compressors, and in particular to an air compressor with an exhaust drying function. Background Art

[0002] Air compressors, as a widely used equipment in the industrial field, mainly convert mechanical energy into gas pressure energy, thereby compressing gas to meet various industrial needs. Traditional air compressors mostly use reciprocating piston, rotary blade or rotary screw working principles. While compressing the gas, these devices also compress the moisture in the air, resulting in the exhaust gas containing a certain amount of humidity.

[0003] In industrial production, compressed air often needs to be dried to prevent moisture from causing adverse effects on production equipment and products. The traditional approach is to install an independent dryer in front of the air compressor, which contains a desiccant that can absorb moisture in the air. However, this traditional drying method has some problems:

[0004] First, when the desiccant absorbs a certain amount of moisture, its drying effect will gradually decrease until it becomes ineffective. At this point, it is necessary to shut down the machine and take out the desiccant for recovery treatment, such as heating and drying, in order to regain its moisture absorption capacity. This process not only affects the normal operation of the air compressor, but may also cause production interruptions and affect production efficiency.

[0005] Secondly, the process of replacing the desiccant is also very cumbersome. Since the dryer is usually installed at the air intake end of the air compressor, replacing the desiccant requires shutting down the machine and disassembling related components, which not only increases maintenance costs, but may also cause equipment damage or safety hazards. Summary of the invention

[0006] The purpose of the present invention is to provide an air compressor with a built-in exhaust drying function to solve the technical problems in the prior art that the desiccant gradually becomes ineffective after absorbing a certain amount of moisture, and needs to be stopped and taken out for recovery treatment, which affects the normal operation and production efficiency of the air compressor; at the same time, the process of replacing the desiccant is cumbersome, and related components need to be stopped and disassembled, which increases the maintenance cost and may cause equipment damage or safety hazards.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 11 As shown, an air compressor with exhaust drying function includes an air storage tank body 1, a mounting frame 2, a first motor 3, an air compression device 4 and a control box 5. The mounting frame 2 is fixedly arranged on the top of the air storage tank body 1, the first motor 3, the air compression device 4 and the control box 5 are all fixedly connected to the mounting frame 2, and the first motor 3 is connected to the air compression device 4 through a belt 6. The top of the air compression device 4 is provided with an exhaust drying mechanism 7.

[0036] When the first motor 3 is started, the air compression device 4 is driven to operate through the belt 6, thereby sucking in and compressing external air, and sending the compressed air into the air storage tank body 1 through the exhaust drying mechanism 7.

[0037] The exhaust drying mechanism 7 includes a drying cylinder 8, a drying rotary disk 9, an isolation plate 10, a desiccant 11, a heating assembly 12, a rotating plate 13, a humidity sensor 14 and a second motor 15. The drying cylinder 8 is fixedly arranged on the top of the air compression device 4. The top of the drying cylinder 8 is relatively provided with a first opening 16 and a second opening 17. The bottom of the drying cylinder 8 is relatively provided with a third opening 18 and a fourth opening 19. The first opening 16 is connected to the air storage tank body 1, and the third opening 18 is connected to the air compression device 4. The drying rotary disk 9 is rotatably arranged in the drying cylinder 8. The drying rotary disk 9 is relatively provided with a first cavity 20 and a second cavity 2 1, through holes are provided at the bottom of the first cavity 20 and the second cavity 21, the isolation plate 10 is fixedly arranged between the first cavity 20 and the second cavity 21, the first cavity 20 and the second cavity 21 are both provided with desiccant 11 and heating assembly 12, the rotating plate 13 is connected with the isolation plate 10, humidity sensors 14 are fixedly arranged on both sides of the rotating plate 13, the second motor 15 is fixedly arranged on the top of the drying cylinder 8, the output end of the second motor 15 is connected with the rotating plate 13, the first motor 3, the air compression device 4, the heating assembly 12, the humidity sensor 14 and the second motor 15 are all electrically connected with the control box 5.

[0038] The compressed air enters the first cavity 20 or the second cavity 21 of the drying cylinder 8 through the third opening 18. In the drying cylinder 8, the air contacts the desiccant 11 and absorbs moisture in the air to achieve the purpose of drying. The dried air then enters the air storage tank body 1 through the first opening 16.

[0039] The humidity sensor 14 monitors the air humidity in the first cavity 20 and the second cavity 21 in real time. When the humidity in a cavity reaches a preset threshold, it indicates that the desiccant 11 in the cavity is close to saturation and needs to be regenerated. After receiving the signal from the humidity sensor 14, the control box 5 starts the second motor 15 to drive the drying turntable 9 to rotate, so that the cavity originally in the working state is switched to the regeneration state, and the other cavity is switched to the working state. The desiccant 11 in the cavity switched to the regeneration state is heated by the heating component 12 to evaporate the absorbed moisture. The evaporated moisture is discharged through the second opening 17 at the top of the drying cylinder 8. By continuously rotating the drying turntable 9, the two cavities are alternately dried and regenerated to ensure that the air compressor continuously outputs dry air. It should be specifically noted that when the cavity is in the working state, the cavity is connected to the first opening 16 and the second opening 17. When the cavity is in the regeneration state, the cavity is connected to the third opening 18 and the fourth opening 19.

[0040] By rotating the drying turntable 9 to change the cavity connected to the first opening 16 and the third opening 18, and the heating component 12 regenerates the wet desiccant 11, production interruption caused by replacing the desiccant 11 is avoided, and the desiccant 11 regeneration without stopping is realized, thereby improving production efficiency. The desiccant 11 can be regenerated without disassembling related components, which simplifies the maintenance process and reduces maintenance costs. The risk of equipment damage caused by stopping to disassemble and replace the desiccant 11 is reduced. The potential safety hazards caused by stopping for maintenance are avoided. Through the cooperation of the humidity sensor 14 and the control box 5, intelligent control of the drying process is realized, and the automation level of the equipment is improved.

[0041] refer to Figure 7 As shown, in some specific embodiments, a filter screen 22 is fixedly provided on the top of the first cavity 20 and the second cavity 21. When the compressed air enters the cavity through the drying cylinder 8, the filter screen 22 can block the desiccant 11 particles to prevent them from being blown up by the airflow and flowing out with the air. The filter screen 22 can also help maintain the uniform distribution of the desiccant 11 in the cavity to prevent it from accumulating in a corner due to the airflow, thereby ensuring that the air in each part can be fully dried. In addition to preventing the desiccant 11 from being blown away, the filter screen 22 can also play a certain degree of filtering role, intercepting and removing impurities and particles in the compressed air, and further improving the quality of the output air.

[0042] refer to Fig. 9 and Fig.11 As shown, in some specific embodiments, an insert block 23 is fixedly provided on the top of the isolation plate 10, and a slot 24 is provided at the bottom of the rotating plate 13 to match the insert block 23. When the drying turntable 9 rotates in the drying cylinder 8, the insert block 23 on the isolation plate 10 is inserted into the slot 24 at the bottom of the rotating plate 13. This cooperation not only ensures a stable connection between the rotating plate 13 and the isolation plate 10, but also ensures the sealing of the first cavity 20 and the second cavity 21 during the rotation of the drying turntable 9.

[0043] refer to Fig. 9 and Fig.10 As shown, in some specific embodiments, a plurality of drying turntables 9 are provided and arranged longitudinally in the drying cylinder 8. An isolation plate 10 is provided in each drying turntable 9, and a slot 24 matching with the plug block 23 is provided at the bottom of the isolation plate 10.

[0044] By arranging a plurality of drying rotary discs 9 in a longitudinal direction, the exhaust drying mechanism 7 can process more air at the same time, thereby improving the overall drying efficiency. Each drying rotary disc 9 works independently, but together constitutes an efficient drying system.

[0045] Inside each drying turntable 9, a slot 24 is provided at the bottom of the isolation plate 10 to match the insert block 23. This ensures that when the rotating plate 13 rotates, each drying turntable 9 will rotate along with it. Through the coordinated work of multiple drying turntables 9, the air compressor can handle more air flow at the same time, thereby significantly improving the drying efficiency.

[0046] refer to Fig. 9 and Fig.10 As shown, in some specific embodiments, the drying turntable 9, the isolation plate 10 and the insert block 23 are integrally formed. The isolation plate 10 is located between the first cavity 20 and the second cavity 21, and plays a role of isolation and support, ensuring that the air between the two cavities will not mix with each other, thereby ensuring the independence of the drying process.

[0047] The one-piece molding ensures a tight fit between the drying disc 9, the isolation plate 10 and the insert 23, thereby improving the sealing of the drying cylinder 8. This helps prevent air leakage and moisture intrusion, further improving the drying effect. The reduction of connection points between components reduces the risk of leakage and failure, thereby improving the overall performance and reliability of the air compressor.

[0048] refer to Figure 2 and Figure 3 As shown, in some specific embodiments, the mounting frame 2 is fixedly provided with a protective cover 25, and the protective cover 25 is located outside the belt 6. The existence of the protective cover 25 effectively isolates the direct contact between the belt 6 and the external environment, reducing the safety risks caused by splashes or accidental touches that may be generated when the belt 6 is running. At the same time, it also prevents injuries caused by accidental contact of the belt 6 by personnel, especially when the belt 6 is in a high-speed running state, this protective measure is particularly important.

[0049] refer to Figure 7 and Figure 8 As shown, in some specific embodiments, the heating assembly 12 includes a plurality of electric heating rods 26 , which are arranged in a matrix on the side of the isolation plate 10 , and the electric heating rods 26 are electrically connected to the control box 5 .

[0050] During the regeneration stage of the desiccant 11, the control box 5 will start the corresponding electric heating rod 26 according to the feedback signal of the humidity sensor 14. After the electric heating rod 26 starts working, it will generate heat, which will increase the temperature of the desiccant 11. As the temperature rises, the moisture absorbed in the desiccant 11 begins to evaporate and form water vapor. The water vapor is then discharged through the opening at the top of the drying cylinder 8, thereby achieving the regeneration of the desiccant 11.

[0051] Since the electric heating rods 26 are arranged in a matrix and each electric heating rod 26 can be independently controlled, the heating power and time can be flexibly adjusted according to the actual regeneration requirements of the desiccant 11. This can not only improve the regeneration efficiency, but also avoid unnecessary energy waste.

[0052] refer to Figure 4 and Figure 5 As shown, in some specific embodiments, a protective net 27 is fixedly provided at the ports of the second opening 17 and the fourth opening 19. The protective net 27 can effectively prevent external foreign matter, such as dust, small particles, insects, etc., from entering the interior of the drying cylinder 8, thereby preventing these foreign matter from damaging key components such as the desiccant 11, the heating assembly 12 or the humidity sensor 14 or affecting their normal operation.

[0053] refer to Figure 7 As shown, in some specific embodiments, the bottom of the first cavity 20 and the second cavity 21 are fixedly provided with a sound-absorbing and sound-insulating cotton 28. The sound-absorbing and sound-insulating cotton 28 has good sound absorption and sound insulation properties, and can effectively absorb and isolate the noise generated during the operation of the equipment, reduce noise pollution, and improve the working environment. The sound-absorbing and sound-inducing cotton 28 can also slow down the airflow speed, making the airflow entering the drying cylinder 8 more stable, reducing the impact of the airflow on the desiccant 11 and the heating component 12, and extending their service life. By slowing down the airflow speed, the sound-absorbing and sound-inducing cotton 28 helps the airflow to contact the desiccant 11 more fully, thereby improving the drying efficiency and ensuring the dry quality of the output air.

[0054] refer to Figure 2 and Figure 3 As shown, in some specific embodiments, a rotating wheel 29 is provided at the bottom of the gas storage tank body 1, and a handle 30 is fixedly provided at the side of the gas storage tank body 1. The rotating wheel 29 enables the gas storage tank body 1 to be easily moved on the ground or other planes without relying on external handling tools or manual lifting, thereby reducing the labor intensity of the operator. The handle 30 enables the operator to have a stable grip point when moving the gas storage tank body 1, thereby enhancing the safety and stability during the movement.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
