Description

Technical Field

[0002] The drying tower is the core component of the zero-air-consumption waste heat regeneration dryer, mainly used for adsorbing and drying the gas to be treated. The zero-air-consumption waste heat regeneration dryer is a high-efficiency and energy-saving drying equipment. Its core advantage lies in using the waste heat of compressed air for regeneration, which greatly reduces air consumption. The working principle of this dryer is to use the heat generated by compressed air during the compression process to directly heat the adsorbent in the drying tower, causing it to desorb and remove the adsorbed moisture.

[0003] Existing zero-air-consumption waste heat regeneration dryers have certain drawbacks in use. In traditional zero-air-consumption waste heat regeneration dryers, the granular adsorbent in the drying tower cannot be stirred. The efficiency of the granular adsorbent at the bottom decreases as it adsorbs moisture from the air, while the granular adsorbent at the top has a higher adsorption efficiency than the bottom. The air circulation in the drying tower is not uniform enough, resulting in low air drying efficiency. Furthermore, the process of replacing the granular adsorbent is not convenient or simple.

The third circular frame 109 is located directly below the second circular frame 108. The electric motor 110 is fixedly installed at the center of the upper surface of the cooler 18. The upper end of the stirring rod 111 is fixedly connected to the lower end of the rotating shaft of the electric motor 110, and the lower end of the stirring rod 111 is inserted into the through hole in the center of the third circular frame 109. The discharge hopper 112 is fixedly installed inside the third circular frame 109. Nine stirring crossbars are installed on the outside of the main rod of the stirring rod 111. The stirring crossbars installed on the main rod of the stirring rod 111 are evenly distributed on the outside of the main rod of the stirring rod 111. The lower end of the discharge hopper 112 is fixedly connected to the upper end of the discharge pipe 104. The feed pipe 103 is located near the cooler 18. There are two limit sleeves 113 and sealing covers 114. Sleeve 113 is fixedly installed at the rear end of feed pipe 103 and discharge pipe 104 respectively. Sealing cover 114 is respectively located inside feed pipe 103 and discharge pipe 104. Fixing sleeve 115 is fixedly installed at the center of the rear surface of sealing cover 114. Handle 116 is fixedly installed on the rear surface of sealing cover 114. Limiting rod 117 is located inside fixing sleeve 115.

Isolation net 120 is fixedly installed inside the second circular frame 108 and the third circular frame 109. The upper end of limiting rod 117 is inserted into the inside of limiting sleeve 113. The lower end of limiting rod 117 passes through the inside of feed pipe 103 and discharge pipe 104 respectively.

[0027] It should be noted that this utility model is a high-efficiency zero-air-consumption waste heat regeneration dryer. In use, in the drying tower 1, remove the screw head 118 at the lower end of the limiting rod 117, pull the limiting rod 117 out of the limiting sleeve 113, then hold the handle 116 and pull the sealing cover 114 out of the feed pipe 103. Pour the granular adsorbent through the feed pipe 103 into the tower shell 101 between the second circular frame 108 and the third circular frame 109. Then, reinstall the sealing cover 114. Inside the feed pipe 103, the upper end of the limiting rod 117 is re-engaged into the limiting sleeve 113, and the limiting rod 117 is re-inserted into the fixing sleeve 115. The screw head 118 is then re-installed into the lower end of the limiting rod 117. The sealing rubber ring 119 provides a seal. During the process of the granular adsorbent absorbing moisture from the gas, the electric motor 110 drives the stirring rod 111 to rotate, stirring the granular adsorbent through the stirring crossbar, thus making the granular adsorbent absorb moisture from the air more effectively. The air is evenly distributed as it passes through the fan blade 107, which rotates accordingly. This disperses the air, ensuring a uniform flow within the tower shell 101. The bearing 106 within the first circular frame 105 facilitates smoother rotation of the fan blade 107. When the granular adsorbent needs replacement, the sealing cap 114 at the lower end of the discharge pipe 104 is removed, and the adsorbent is discharged along the discharge hopper 112 and discharge pipe 104. Then, the inside of the feed pipe 103 is opened, and the sealing cap 114 is reinstalled inside the discharge pipe 104. The granular adsorbent is then poured into the tower shell 101 between the second circular frame 108 and the third circular frame 109 through the feed pipe 103. The upper end of the feed pipe 103 is then closed. This process in the drying tower 1 allows the granular adsorbent to be evenly stirred, resulting in more uniform absorption of moisture from the air. The airflow within the drying tower 1 is more uniform, leading to higher air drying efficiency and better drying effect. Furthermore, the replacement process for the granular adsorbent is more convenient and simpler.
