Description

Technical Field

[0001] This application relates to the field of drying equipment, specifically to a drying apparatus for manufacturing adsorbent pellets. Background Technology

[0002] The harm of VOCs in the atmosphere to humans and nature is immeasurable. Adsorption methods for treating VOCs have long been a focus of attention due to their advantages in operation, simplicity, and low cost. Adsorption methods generally use porous materials with certain adsorption properties as adsorbents, such as activated carbon, molecular sieves, and Al2O3. Preparing porous VOCs adsorbent microspheres from fly ash from coal-fired power plants not only provides a new product for VOCs adsorption but also achieves "waste treatment with waste," realizing the stabilization and resource utilization of fly ash.

[0003] After the adsorbent pellets are prepared, they need to be dried. In existing related technologies, the adsorbent pellets are generally dried by sun exposure or oven heating. However, the former has low drying efficiency, is highly dependent on the weather, and requires a large area for spreading. Although the latter can improve the drying efficiency to a certain extent, it requires a large amount of electricity. Moreover, when the adsorbent pellets are stacked in the oven, the adsorbent pellets on the inner side are difficult to dry. Utility Model Content

The material collection tray is umbrella-shaped with a large inner diameter at the top and a small inner diameter at the bottom.

[0023] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] like Figure 1-4 As shown, the drying device for manufacturing adsorbent microspheres includes a drying tank 1, a cover 2, a drying tray 3, an air inlet pipe 4, a riser pipe 5, and an extension pipe 6. The cover 2 is located on top of the drying tank 1, the drying tray 3 is located on the lower inner side of the drying tank 1, the air inlet pipe 4 is inserted into the bottom of the drying tray 3 and communicates with the cavity inside the drying tray 3, the riser pipe 5 is located between the cover 2 and the drying tray 3 and communicates with the cavity, and the extension pipe 6 is located on the outer wall of the riser pipe 5. A first air outlet 30 is provided on the drying tray 3, and a second air outlet 60 is provided on the extension pipe 6. Both the first air outlet 30 and the second air outlet 60 can spray drying hot air outwards. The drying hot air can be sprayed onto the adsorbent microspheres from multiple positions, improving the drying efficiency and uniformity of the adsorbent microspheres and avoiding the problem of the inner microspheres being difficult to dry.

[0025] The drying tank 1 is used to contain adsorbent pellets for drying. The lid 2 is located on top of the drying tank 1, serving to seal the drying tank 1. There may be a gap between the lid 2 and the drying tank 1, or an exhaust port may be provided on the lid 2. In this way, the drying hot air flows from bottom to top and from inside to outside, which can reliably carry away the moisture inside the adsorbent pellets, thereby achieving the drying of the adsorbent pellets.

[0026] A drying tray 3 is located on the lower inner side of the drying tank 1, and a cavity is provided inside the drying tray 3. The outer wall of the drying tray 3 is adapted to the inner wall of the drying tank 1. The top of the drying tray 3 has several first air outlets 30 communicating with the cavity. The first air outlets 30 can be small circular holes or strip-shaped slits. The function of the first air outlets 30 is to spray the drying hot air entering the cavity onto the adsorbent spheres inside the drying tank 1. An air inlet pipe 4 is located at the bottom of the drying tank 1 and can be inserted into the bottom of the drying tray 3 and communicate with the cavity. The air inlet pipe 4 is connected to the drying tray 3 by insertion, ensuring that the drying tray 3 can be repeatedly connected and disconnected from the air inlet pipe 4. The function of the air inlet pipe 4 is to introduce the drying hot air into the cavity of the drying tray 3.

[0027] A riser 5 is positioned between the cover 2 and the drying tray 3, and communicates with the cavity. One end of the riser 5 is fixedly connected to the drying tray 3 and communicates with the cavity, while the other end is connected to the bottom of the cover 2 and sealed by the cover 2. The function of the riser 5 is to guide the drying hot air in the cavity of the drying tray 3 to the upper part of the drying tank 1. An extension pipe 6 is positioned on the outer wall of the riser 5, with one end communicating with the riser 5 and the other end closed. Several second air outlets 60 are provided on the outer wall of the extension pipe 6, and the form of the second air outlets 60 is similar to that of the first air outlets 30. The function of the extension pipe 6 is to guide the hot air from the riser 5 to various positions in the drying tank 1, so that the adsorbent beads can be in more uniform contact with the hot air.

[0028] Multiple extension tube groups are provided on the outer side of the riser 5. Each extension tube group consists of at least three extension tubes 6 spaced apart vertically. The multiple extension tube groups are spaced apart circumferentially along the riser 5, which allows the hot air to be more widely distributed within the drying tank 1. The extension tubes 6 within each extension tube group are parallel to each other, and the angle between the extension tubes 6 in two adjacent extension tube groups and the riser 5 is not uniform, further increasing the range and uniformity of hot air injection.

[0029] A collection tray 7 is provided in the middle of the outer wall of the drying tank 1. The collection tray 7 is umbrella-shaped with a larger inner diameter at the top and a smaller inner diameter at the bottom. The function of the collection tray 7 is to collect the dried adsorbent pellets. A discharge pipe 70 is provided at the bottom of the collection tray 7, which extends downward and is used to discharge the dried material. A gantry 8 is provided on the outer side of the drying tank 1. A winch 9 is provided at the horizontal end of the gantry 8. The cable of the winch 9 is connected to the top of the cover 2. The winch 9 can be an electric winch 9, which drives the winding and unwinding of the cable through a motor. A pair of limiting blocks 21 are provided on the outer wall of the cover 2. The limiting blocks 21 have a slot 22 on the side facing the vertical end of the gantry 8. The vertical end of the gantry 8 is adapted to fit in the slot 22. The cover 2 slides up and down between the vertical ends of the gantry 8. The shape of the slot 22 is adapted to the vertical end of the gantry 8 to ensure the stability of the cover 2 during the up and down sliding process. Furthermore, by repeatedly lifting and lowering the cover 2, the riser 5, and the drying tray 3 using the winch 9, the adsorbent balls can be disturbed through several extension tubes 6, thereby improving the drying effect.

[0030] The implementation principle of this embodiment is as follows: Drying hot air is introduced into the cavity of the drying tray 3 through the air inlet pipe 4. The drying hot air is sprayed onto the adsorbent balls inside the drying tank 1 through the first air outlet 30. Simultaneously, drying hot air is sprayed to various positions in the drying tank 1 through the second air outlet 60 on the extension pipe 6, ensuring that the adsorbent balls are dried more evenly. The dried adsorbent balls fall onto the collection tray 7 and are discharged through the discharge pipe 70. The winch 9 can control the up-and-down movement of the cover 2, facilitating the placement and removal of the adsorbent balls.

[0031] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
