Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to a dryer that can prevent air quality degradation. Background Technology

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects by heating them to vaporize and remove the moisture (generally water or other volatile liquid components) to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing.

[0003] Based on operating pressure, dryers are divided into two categories: atmospheric pressure dryers and vacuum dryers. According to operating pressure, they can be divided into atmospheric pressure dryers and vacuum dryers (vacuum dryers are also called vacuum dryers). The entry also provides detailed information on adsorption dryers, refrigerated dryers, and microwave dryers.

[0004] However, the following problems were found in the implementation of the relevant technology: there is only one manual valve in the inlet pipe of the three dryers. When the dryer is stopped, the operator needs to go to the site to close the inlet manual valve. Otherwise, the humid air from the air compressor will be supplied directly to the instrument compressed air system without being processed by the drying furnace, which will cause the quality of the instrument compressed air to deteriorate and affect the normal use of subsequent pneumatic equipment. Therefore, a dryer that can avoid the deterioration of air quality is proposed. Utility Model Content

[0005] This invention proposes a dryer that can avoid air quality degradation, solving the problem in related technologies where there is only one manual valve. When the dryer is stopped, the operator needs to go to the site to close the inlet manual valve. Otherwise, the humid air from the air compressor will be directly supplied to the instrument compressed air system without being processed by the drying furnace, causing a decline in the quality of the instrument compressed air and affecting the normal use of subsequent pneumatic equipment.

[0006] The technical solution of this utility model is as follows:

[0007] A dryer that avoids degrading air quality includes: a fixed base;

[0008] Three dryer bodies are arranged sequentially from left to right on the fixed base. Each of the three dryer bodies has an air inlet pipe fixedly connected to its air inlet end, and a pneumatic check valve is installed on the air inlet pipe.

[0009] The end of the air inlet pipe away from the dryer body is fixedly connected to the main air inlet pipe, and a manual valve and a pneumatic butterfly valve are respectively provided at opposite ends of the outer wall of the main air inlet pipe.

[0010] The exhaust end of each of the three dryers is fixedly connected to an exhaust pipe. The end of the exhaust pipe away from the main body is fixedly connected to a main exhaust pipe. A pneumatic butterfly valve is provided at the end of the outer wall of the main exhaust pipe.

[0011] The testing facility is located at the outlet of the main exhaust pipe;

[0012] Two support and buffer mechanisms are respectively located below the main air inlet pipe and the main air outlet pipe.

[0013] Preferably, the detection mechanism includes a fixing frame fixedly installed on the fixing base, and the fixing frame is located at the discharge end of the main exhaust pipe.

[0014] Preferably, the online dew point detector is fixedly installed on the top of the mounting frame, and a fixing clip is fixedly installed on the inner top wall of the mounting frame. A probe is attached to the fixing clip, and the probe is electrically connected to the online dew point detector.

[0015] Preferably, an audible and visual alarm is fixedly installed on the top of the mounting bracket. The audible and visual alarm is located on the rear side of the online dew point detector, and the online dew point detector and the audible and visual alarm are electrically connected through a controller.

[0016] Preferably, the two support and buffer mechanisms include two U-shaped fixing plates fixedly installed on the top of the fixed base, multiple sliding rods movably passing through the top of the U-shaped fixing plates, and pipe clamps fixedly installed on the top of the multiple sliding rods.

[0017] Preferably, the top of the U-shaped fixture is fixedly equipped with a plurality of springs and a plurality of dampers, with the plurality of dampers and springs spaced apart.

[0018] Preferably, a sealing device is provided at the connection between the intake pipe and the main intake pipe. The sealing device is used to ensure an airtight connection between the intake pipe and the main intake pipe. The sealing device includes a rubber sealing ring, which is disposed at the end of the connection between the intake pipe and the main intake pipe and is fixed by fasteners.

[0019] Preferably, the damper and spring are connected to the top of the U-shaped fixed plate via a connecting seat, which is fixed to the inside of the top of the U-shaped fixed plate, so that the damper and spring are supported and spaced apart.

[0020] The working principle and beneficial effects of this utility model are as follows:

[0021] By installing a pneumatic butterfly valve on one side of the manual valve on the main air inlet pipe for linkage with the dryer's operating status, the pneumatic butterfly valve automatically closes when the dryer stops. By installing pneumatic check valves on the inlet pipes of the three dryers for an automated interlocking mechanism, the reverse flow of humid air is completely blocked, ensuring the drying quality of the instrument compressed air system when the dryers are not in operation. This achieves a shift from passive emergency response to active defense, fundamentally solving the problem of humid air leakage during shutdown, effectively avoiding the problem of air quality degradation, and thus improving the efficiency of the dryers.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] Example 1

[0032] Please see Figure 1- Figure 4 A dryer that can prevent air quality degradation includes: a fixed base 1; three dryer bodies 2 arranged sequentially from left to right on the fixed base 1; each of the three dryer bodies 2 has an air inlet pipe 3 fixedly connected to its air inlet end; a pneumatic check valve 4 is installed on the air inlet pipe 3; a main air inlet pipe 5 is fixedly connected to the end of the air inlet pipe 3 away from the dryer body 2; a manual valve 7 and a pneumatic butterfly valve 6 are respectively installed opposite each other on the outer wall of the main air inlet pipe 5; an exhaust pipe 8 is fixedly connected to the exhaust end of each of the three dryer bodies 2; a main air outlet pipe 9 is fixedly connected to the end of the exhaust pipe 8 away from the exhaust end; and a pneumatic butterfly valve 10 is installed on the outer wall of the main air outlet pipe 9.

[0033] Efficient airflow control: By setting pneumatic check valve 4 and pneumatic butterfly valve 6 and pneumatic butterfly valve 10, the intake and exhaust flow can be precisely controlled to ensure stable airflow during the drying process, thereby improving the drying effect; pneumatic check valve 4 can effectively prevent air backflow and ensure that the air quality in the intake pipe 3 is not polluted by the external environment, thereby avoiding the deterioration of the air quality inside the dryer.

[0034] Manual valve 7 and pneumatic butterfly valve 6 provide flexible airflow adjustment, allowing users to adjust the airflow speed and pressure according to actual needs to ensure optimized drying process. Meanwhile, pneumatic butterfly valve 10 effectively controls exhaust on the exhaust pipe, reducing the backflow of external contaminants. The three dryer bodies 2 can simultaneously handle the drying needs of multiple work areas, improving work efficiency and ensuring balanced system load, preventing any single device from overloading.

[0035] By optimizing intake and exhaust control, unnecessary air waste is reduced, the overall energy efficiency of the system is improved, and energy consumption is reduced. The entire system integrates the components through the fixed base 1, which helps to reduce interference between devices and facilitates the installation and maintenance of the equipment.

[0036] This utility model provides a dryer that can prevent air quality degradation. By installing a pneumatic butterfly valve 6 on one side of the manual valve 7 on the main air inlet pipe 5, it is used for linkage of the dryer's operating status. When the dryer stops, the pneumatic butterfly valve 6 automatically closes. By installing pneumatic check valves 4 on the inlet pipes of the three dryers, an automatic interlocking mechanism is used to completely block the reverse flow of humid air, ensuring the drying quality of the instrument compressed air system when the dryer is not in operation. This realizes the transformation from passive emergency to active defense, fundamentally solving the problem of humid air leakage under shutdown conditions, effectively avoiding the problem of air quality degradation, and thus improving the efficiency of the dryer.

[0037] The existing manual valve 7 is retained as a backup for maintenance isolation.

[0038] Example 2

[0039] Based on Embodiment 1, this embodiment includes: a detection mechanism 11, which is located at the outlet of the main exhaust pipe 9. The detection mechanism 11 includes a fixed bracket 111 fixedly mounted on the fixed base 1, and the fixed bracket 111 is located at the outlet end of the main exhaust pipe 9. A dew point online detector 114 is fixedly mounted on the top of the fixed bracket 111. A fixing clip 112 is fixedly mounted on the inner top wall of the fixed bracket 111. A probe 113 is attached to the fixing clip 112. The probe 113 is electrically connected to the dew point online detector 114. An audible and visual alarm 115 is fixedly mounted on the top of the fixed bracket 111. The audible and visual alarm 115 is located behind the dew point online detector 114. The dew point online detector 114 and the audible and visual alarm 115 are electrically connected through a controller.

[0040] By installing the online dew point detector 114, the dew point at the exhaust port of the main exhaust pipe 9 can be monitored in real time, ensuring that the humidity of the exhaust gas is controlled within a suitable range, thereby avoiding adverse effects on the equipment or environment due to excessive humidity or dryness; the electrical connection between the probe 113 and the online dew point detector 114 ensures that the data acquired by the probe can be transmitted to the dew point detector in a timely and accurate manner, ensuring the real-time performance and accuracy of the data.

[0041] The audible and visual alarm 115 is electrically connected to the online dew point detector 114 via a controller. Once the dew point value exceeds the set range, the audible and visual alarm 115 will promptly issue an alarm to remind the operator to take measures to prevent equipment failure or performance degradation caused by excessive dew point. The audible and visual alarm 115 is located on the rear side of the online dew point detector 114, making it easy for the operator to clearly hear and see the alarm signal, thus improving the system's response efficiency and safety.

[0042] The detection mechanism 11, through the cooperation of the fixing frame 111, fixing clip 112 and other components, ensures the stable installation of the online dew point detector and probe, reduces errors caused by vibration or external interference, and improves the service life and stability of the monitoring equipment. The design of the detection mechanism 11 makes it easy to connect and disassemble the various components, facilitates regular inspection and maintenance, and ensures the reliability and accuracy of the system in long-term operation.

[0043] The technical solution provided in this embodiment is as follows: the gas emitted from the main exhaust pipe 9 is detected by probe 113, and the detection is transmitted to the online dew point detector 114. The online dew point detector 114 is used to measure the dew point temperature in the compressed air. The dew point temperature is the temperature at which air is cooled to saturation under the condition that the water vapor content and air pressure do not change. By monitoring this indicator, the moisture content in the compressed air can be understood, and it can be determined whether the air is too humid. This effectively avoids secondary losses caused by humid air, such as the cost of pneumatic equipment failure (e.g., valve jamming, instrument malfunction), and can reduce costs by 90%.

[0044] The 115 audible and visual alarm system locates fault points through audible and visual alarms, shortening the processing time for maintenance personnel upon arrival.

[0045] Example 3

[0046] Based on Embodiment 1, this embodiment includes: two support and buffer mechanisms 12, respectively located below the main air inlet pipe 5 and the main air outlet pipe 9. The two support and buffer mechanisms 12 include two U-shaped fixed plates 121 fixedly installed on the top of the fixed base 1, multiple sliding rods 122 movably passing through the top of the U-shaped fixed plates, and pipe clamps 125 fixedly installed on the top of the multiple sliding rods 122. Multiple springs 123 and multiple dampers 124 are fixedly installed on the top of the U-shaped fixed plates 121, and the multiple dampers 124 and multiple springs 123 are spaced apart.

[0047] By setting multiple springs 123 and dampers 124, the support and buffer mechanism 12 can effectively reduce the vibration and impact generated during the operation of the equipment, reduce the damage caused by uneven force on the equipment, and extend the service life of the equipment. The U-shaped fixing plate 121 and the slide rod 122 jointly fix the pipe clamp 125, providing a stable support function, ensuring that the main air inlet pipe 5 and the main air outlet pipe 9 maintain a stable position during operation, and preventing the pipes from shifting due to vibration or external force.

[0048] The design of multiple sliding rods 122 enables the support and buffer mechanism 12 to adapt to the installation requirements of different pipelines. At the same time, it can be adjusted by sliding during movement to ensure that the pipeline is fixed more flexibly, which is convenient for installation and maintenance. The spaced arrangement of springs 123 and dampers 124 forms a dual energy absorption structure, which can better absorb the impact and vibration generated by the operation of the equipment and improve the overall stability of the system.

[0049] The design of the support buffer mechanism 12 can effectively alleviate the instability caused by vibration and impact, ensuring that the pipeline system can still maintain efficient and stable operation under high-intensity operation and reducing the failure rate; the independent setting of springs and dampers makes replacement and maintenance more convenient, reduces interference with other structures, and lowers maintenance costs and time; through reasonable buffer design, the risk of pipeline being subjected to excessive impact and pressure can be reduced, avoiding pipeline rupture or equipment damage caused by impact, and improving system safety.

[0050] The technical solution provided in this embodiment is as follows: the pipe clamp 125 is used to clamp and fix the main air inlet pipe 5 and the main air outlet pipe 9, and the two support and buffer mechanisms 12 respectively support and fix the main air inlet pipe 5 and the main air outlet pipe 9.

[0051] When shaking occurs, the shaking force linkage slide rod 122 slides on the U-shaped fixed plate 121. With the cooperation of multiple springs 123 and multiple dampers 124, it is used to slide against the shaking force, effectively buffering the shaking and effectively improving the stability of the main air inlet pipe 5 and the main air outlet pipe 9, preventing the valves installed on the main air inlet pipe 5 and the main air outlet pipe 9 from becoming loose due to shaking.

[0052] A sealing device is provided at the connection between the intake pipe 3 and the main intake pipe 5. The sealing device is used to ensure an airtight connection between the intake pipe and the main intake pipe. The sealing device includes a rubber sealing ring, which is located at the end of the connection between the intake pipe and the main intake pipe and is fixed by fasteners. The damper 124 and the spring 123 are connected to the top of the U-shaped fixing plate 121 through a connecting seat. The connecting seat is fixed on the inner side of the top of the U-shaped fixing plate to enable the damper and the spring to be supported and spaced apart.

[0053] By installing a rubber sealing ring at the connection between the intake pipe 3 and the main intake pipe 5 and fixing it with fasteners, the airtight connection between the intake pipe and the main intake pipe can be effectively guaranteed, preventing gas leakage and ensuring the stability of airflow and the working efficiency of the system.

[0054] The sealing device is designed to ensure that the connection remains sealed even under high pressure or high temperature environments, preventing gas leakage or equipment damage caused by environmental changes and improving system safety and reliability. Connecting the damper 124 and spring 123 to the top of the U-shaped fixing plate 121 via the connecting seat ensures optimal support and spacing for the damper and spring. This structure helps to reduce equipment vibration, decrease shock transmission, and improve equipment stability.

[0055] The dampers and springs effectively reduce the impact of external shocks on the equipment, preventing damage from vibration or impact. A well-designed spacing further enhances the structure's seismic resistance and stability. The sealing device uses rubber sealing rings for easy replacement and maintenance. When the sealing rings age or are damaged, they can be quickly replaced, minimizing equipment downtime. Furthermore, the dampers and springs are connected to the fixed plate via connecting seats, facilitating inspection and maintenance and reducing maintenance complexity.

[0056] The design of sealing devices and buffer systems can effectively reduce system damage caused by gas leakage and vibration, thereby extending the service life of the equipment. This sealing and buffering design can adapt to different working environments, ensuring good working performance under various operating conditions and is not easily affected by external changes.

[0057] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
