Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying equipment, in particular to a drying device for gas preparation. Background Art
[0002] During the nitrogen preparation process, drying the nitrogen can effectively remove moisture from the nitrogen and reduce its humidity. This helps prevent adverse effects caused by moisture in the nitrogen during subsequent use, such as equipment corrosion and product moisture.
[0003] There are two methods for drying nitrogen: contact and non-contact. Non-contact drying requires heat transfer through a medium, resulting in low drying efficiency. Contact drying achieves this by passing nitrogen through a drying mesh. However, the contact time between nitrogen and the mesh is limited, making effective drying difficult. Furthermore, nitrogen contains not only water but also solid impurities that require filtration. Ensuring effective filtration over a long period of time is a challenging issue. Utility Model Content

In order to simplify the disclosure of the embodiments of the present invention, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.
[0051] Example 1
[0052] A drying device for gas preparation, such as Figures 1 to 5 As shown, it includes a container 1, a guide plate 2 provided in the container 1 and capable of guiding the gas, and a drying mechanism for drying and filtering the gas. The gas includes but is not limited to nitrogen, compressed air, etc., and nitrogen is used as an example for specific description below.
[0053] The container 1 is preferably a box. Of course, in some other embodiments, the container 1 may also be a cylinder or other shapes, without specific limitation. The container 1 has an air inlet pipe 11 and an air outlet pipe 12 arranged on opposite sides thereof. The air inlet pipe 11 introduces gas into the container 1, and the air outlet pipe 12 is used to pass other gases out of the container 1. A fan 13 is installed on one or both of the air inlet pipe 11 and the air outlet pipe 12 to drive the nitrogen to move so that it enters from the air inlet pipe 11 and exits from the air outlet pipe 12. The fan 13 may be an axial flow fan. The specific structure of the axial flow fan can refer to the prior art and is not limited in this application. In this embodiment, the air inlet pipe 11 and the air outlet pipe 12 are located on the upper and lower sides of the container 1, and the fan 13 is installed in the air inlet pipe 11.
[0054] like Figure 2 and Figure 3As shown, a plurality of guide plates 2 are staggered within the container 1, configured to direct nitrogen entering the container 1 from the inlet pipe 11 along an S-shaped path into the outlet pipe 12. In this embodiment, the plurality of guide plates 2 are sequentially arranged along the height direction of the container 1 and are mutually parallel. Preferably, the guide plates 2 are perpendicular to the height direction of the container 1, with one end fixedly connected to a side wall of the container 1 and the other end having a gap between it and the side wall opposite to the side wall. Nitrogen can pass through this gap along the extension direction of the guide plates 2 and enter the next layer of guide plates 2, thereby forming an S-shaped movement path, which is longer.
[0055] The drying mechanism passes through multiple guide plates 2 and is arranged in the container 1, so that the nitrogen is processed by the drying mechanism multiple times under the action of the guide plates 2, and the processing effect is better. Specifically, the drying mechanism is located in the middle part of the container 1 and extends along the height direction of the container 1. When the nitrogen enters the container 1 from the air inlet pipe 11, the nitrogen moves along the extension direction of the guide plate 2 closest to the air inlet pipe 11 (the topmost guide plate, i.e., the first layer of guide plates). Due to the obstruction of the drying mechanism, the nitrogen will first be processed by the drying mechanism and then enter the second layer of guide plates 2 through the gap between the guide plates 2. At this time, it will be blocked by the drying mechanism again and the nitrogen will be processed by the drying mechanism again. In this way, it passes through multiple guide plates 2 and is processed by the drying mechanism multiple times until it is discharged from the air outlet pipe 12. By coordinating the guide plates 2 and the drying mechanism, multiple drying treatments of the nitrogen can be achieved, ensuring the quality of the nitrogen drying treatment.
[0056] Furthermore, the drying mechanism includes a self-cleaning filter assembly 4 and a drying element. The filter assembly 4 includes a filter belt 41, a drive assembly configured to control the reciprocating motion of the filter belt 41, and a scraper assembly 5 abutting against the filter belt 41. The drive assembly includes a drive roller 42 disposed on the inner side of the filter belt 41 and a power source connected to the drive roller 42 and configured to rotate the drive roller 42. The drive roller 42 has two rollers disposed at both ends of the filter belt 41, one of which is a driving roller connected to a power source, which may be a drive motor 43, and the other is a driven roller. By rotating the drive roller 42 about its own axis (which extends along the width of the container 1), the reciprocating motion of the filter belt 41 is achieved, thereby increasing the uniformity of the nitrogen filtration. To facilitate the installation and movement of filter belt 41, guide plate 2 is provided with a groove that matches filter belt 41. Filter belt 41 passes through the groove and connects to drive roller 42. The groove wall does not contact filter belt 41, so when filter belt 41 moves, there is no friction between guide plate 2 and filter belt 41. A drying element is located inside filter belt 41 and is a drying mesh plate 3. The specific structure can be referenced in the prior art. The drying element can be fixed within container 1 via mounting rods 31.
[0057] The scraper assembly 5 may optionally be provided with one or more groups. In this embodiment, the scraper assembly 5 includes two groups, one located above and one below the filter belt 41. Taking one group as an example, the scraper assembly 5 includes a scraper 51, an elastic member 53 for abutting the scraper 51 between the container 1 and the filter belt 41, and a telescopic member 52 connected between the scraper 51 and the container 1. Controlled by the elastic member 53, the scraper 51 tends to move toward the filter belt 41. That is, the elastic member 53 constantly abuts the scraper 51 against the filter belt 41. Thus, when the filter belt 41 moves, the scraper 51 can scrape away impurities and other foreign matter, ensuring that the filter belt 41 can continuously and efficiently filter the nitrogen. The elastic member 53 may be a compression spring. The telescopic member 52 can be extended and retracted along the compression direction of the elastic member 53 (in this embodiment, the compression direction is the vertical direction). It can be formed by multiple sliding sleeves, or can be referred to in the prior art. In this embodiment, the telescopic member 52 is mainly formed by a plurality of sleeves, two of which are arranged along the extending direction of the scraper 51 , and an elastic member 53 is sleeved on each telescopic member 52 .
[0058] In order to ensure the stability of the connection between the scraper 51 and the telescopic member 52 , the scraper assembly 5 further includes a base 54 provided between the scraper 51 and the telescopic member 52 .
[0059] Working principle:
[0060] Fan 13 is activated, drawing the nitrogen to be processed into container 1 through inlet pipe 11. The nitrogen entering container 1 passes through the first layer of guide plates 2 in sequence and enters the drying mechanism. After being filtered, dried, and filtered again, it moves along the extension direction of the first layer of guide plates 2 and passes through the gap between the first layer of guide plates 2 and the inner wall of container 1 to enter the second layer of guide plates 2. After being guided by the second layer of guide plates 2, it enters the drying mechanism again for treatment. It then moves along the extension direction of the second layer of guide plates 2 and passes through the gap between the second layer of guide plates 2 and the interior of container 1 to enter the next layer of guide plates 2. After being guided by all the guide plates 2, it exits through outlet pipe 12. Under the action of the guide plates 2, the nitrogen is treated by the drying mechanism once each time it passes through a layer of guide plates 2. Multiple treatments by the drying mechanism ensure the efficiency of the nitrogen drying process while improving the quality of the nitrogen drying process.
[0061] During the nitrogen processing process, the power source drives the drive roller 42 to rotate, driving the filter belt 41 in reciprocating motion. This allows the filter belt 41 to more evenly filter impurities in the nitrogen, thereby removing impurities and contaminants and improving its purity. Furthermore, during the movement of the filter belt 41, the elastic member 53 exerts a squeezing force on the scraper 51, keeping the scraper 51 against the outside of the filter belt 41. This movement of the filter belt 41 scrapes away foreign matter adsorbed on the surface of the filter belt 41, ensuring that the filter belt 41 continuously and efficiently filters the nitrogen, eliminating the cost of frequent replacement of the filter belt 41.
