Description

Technical Field

[0001] This invention belongs to the field of drying tower technology, and in particular relates to a drying tower structure based on an adsorption dryer. Background Technology

[0002] Adsorption dryers utilize the properties of adsorbents to adsorb moisture, thereby reducing the moisture content in compressed air and achieving a drying effect. They are widely used in compressed air drying operations in fields such as pharmaceuticals, food processing, brewing, and chip manufacturing.

[0003] In existing adsorption drying towers, a distributor is installed inside the tower body to ensure that the moisture in the compressed air is fully absorbed by the adsorbent. However, the high flow rate of the compressed air can impact the adsorbent in the distributor to a certain extent, causing it to weather and block the dryer pipes. Furthermore, the adsorbent gradually loses its activity and becomes ineffective over long-term use, requiring regular replacement. However, the current method of replacing the adsorbent is very inconvenient and makes it difficult to maintain the drying tower body in the future. Summary of the Invention

[0004] The purpose of this invention is to provide a drying tower structure based on an adsorption dryer. By using a double-conical distributor to fill the adsorbent, and with the action of the conical baffle, the compressed gas entering the upper tower end cylinder is buffered, reducing the flow rate of the compressed air, slowing down the weathering rate of the adsorbent filled in the distributor, and facilitating the replacement of the adsorbent, the aforementioned problems are solved.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a drying tower structure based on an adsorption dryer, comprising a cylinder, wherein an upper tower end cylinder and a lower tower end cylinder are respectively fixedly connected to the top and bottom of the cylinder by a first bolt.

[0007] The top and bottom of the cylinder are respectively fixedly connected to two distributors by a second bolt; a first connecting pipe is threaded between the two distributors.

[0008] An end pipe is provided on the inner circumferential side of the upper tower end cylinder; a first end cap is threaded to one end of the end pipe near the outer wall of the upper tower end cylinder; a second connecting pipe is threaded to the other end of the end pipe; the other end of the second connecting pipe is threaded to one of the distributors; a second end cap is threaded to the bottom of the distributor located at the bottom.

[0009] The bottom of the lower tower end cylinder is provided with an installation frame; the top of both ends of the installation frame and on both sides of the cylinder are rotatably connected to rotating screws; the circumferential side of the rotating screws is threaded with lifting guide seats; the two lifting guide seats are respectively threaded with two connecting screws on the side near the cylinder; the other end of the connecting screws is threaded with the cylinder.

[0010] The distributor has a conical structure; the distributor has an internal cavity; a distribution pipe is located at the center of the cavity; two conical baffles are respectively provided on the peripheral side of the distribution pipe and inside the cavity; filter holes are arranged in an array between the two surfaces of the distributor and the conical baffles; inlet holes are arranged in an array on the peripheral side of the distribution pipe and between two adjacent conical baffles; and threaded discharge holes communicating with the cavity are provided on the outer peripheral side of the distributor.

[0011] The cylindrical body has a third end cap connected to its circumferential side via a threaded discharge hole.

[0012] As a preferred embodiment of the present invention, a sealing ring is provided between the two ends of the cylinder and the upper and lower tower end cylinders; the outer peripheral side surfaces of the two ends of the cylinder are provided with mounting ears that cooperate with the first bolt in an annular array.

[0013] As a preferred embodiment of the present invention, the outer peripheral side of the cylinder is provided with a first threaded end sleeve and a through hole that cooperate with the connecting screw and the third end cap.

[0014] As a preferred embodiment of the present invention, a reflux guide plate is fixedly provided inside the upper tower end cylinder and on the circumferential side of the end pipe; the reflux guide plate has an inverted conical structure.

[0015] As a preferred embodiment of the present invention, the mounting frame includes a base frame; mounting holes are provided on both sides of the base frame; support columns are vertically fixed on both sides of the frame; a rectangular groove is provided between the top two sides of the support column; the top and bottom of the rectangular groove are rotatably connected to the rotating screw through ball bearings.

[0016] As a preferred embodiment of the present invention, the lifting guide includes a limiting guide block that cooperates with the rectangular groove; a threaded hole that cooperates with the rotating screw is provided between the two ends of the limiting guide block; and two second threaded end sleeves that cooperate with the connecting screw are respectively provided on one side of the limiting guide block.

[0017] As a preferred embodiment of the present invention, a hexagonal rotating head is fixedly provided on the circumferential side of the connecting screw near the end of the cylinder.

[0018] The present invention has the following beneficial effects:

[0019] 1. This invention uses a double-conical distributor to fill the adsorbent, and the compressed gas entering the upper tower end cylinder is buffered by the action of the conical baffle, which reduces the flow rate of the compressed air and slows down the weathering rate of the adsorbent filled in the distributor. The adsorbent in the distributor can be directly replaced through the end pipe, the second connecting pipe and the first connecting pipe, and discharged through the threaded discharge hole, which facilitates the replacement and maintenance of the adsorbent in the later stage.

The lifting guide seat is connected to the tower body, which consists of the cylinder, the upper tower end cylinder, and the lower tower end cylinder, via the connecting screw. When the rotating screw rotates, it engages with the lifting guide seat through a threaded connection, causing the entire tower body to rise. This facilitates the disassembly and maintenance of the tower body, making the operation simple and meeting the needs of practical use.

The system is connected by two connecting screws 12; the other end of the connecting screws 12 is threadedly engaged with the cylinder 1; the lifting guide seat 11 includes a limiting guide block 1101 that engages with the rectangular groove 904; a threaded hole 1102 that engages with the rotating screw 10 is provided between the two ends of the limiting guide block 1101; two second threaded end sleeves 1103 that engage with the connecting screws 12 are provided on one side of the limiting guide block 1101; the distributor 6 has a conical structure; a cavity 601 is provided inside the distributor 6; a distribution pipe 602 is provided at the center of the cavity 601; two conical partitions 603 are provided on the circumferential side of the distribution pipe 602 and inside the cavity 601; filter holes 6 are arrayed between the two surfaces of the distributor 6 and the conical partitions 603. 04; The feed pipe 602 has feed holes 605 arranged in an array on its circumferential side between two adjacent conical partitions 603; The distributor 6 has a threaded discharge hole 606 that communicates with the cavity 601 on its outer circumferential side; The cylinder 1 has a third end cap 15 threadedly connected to its circumferential side through the threaded discharge hole 606; Sealing rings 16 are provided between the two ends of the cylinder 1 and the upper tower end cylinder 3 and the lower tower end cylinder 4; Mounting ears 101 that cooperate with the first bolt 2 are arranged in an annular array on the outer circumferential side of both ends of the cylinder 1; The outer circumferential side of the cylinder 1 has a first threaded end sleeve 102 and a through hole 103 that cooperate with the connecting screw 12 and the third end cap 15 respectively; A hexagonal rotating head 1201 is fixedly provided on the circumferential side of the connecting screw 12 near the cylinder 1.

[0036] A specific application of this embodiment is as follows: two distributors 6 are fixedly connected to the inner wall of the cylinder 1 by the second bolt 5, and the two distributors 6 are connected to each other by the first connecting pipe 7. The distributor 6 located at the bottom is sealed at the bottom end of its distribution pipe 602 by the second end cap 14. The distributor 6 located at the top is connected to the end pipe 301 inside the upper tower end cylinder 3 by the second connecting pipe 8. The upper tower end cylinder 3 and the lower tower end cylinder 4 are connected to the cylinder 1 by the first bolt 2 to form a tower body. Under the action of the sealing ring 16, the connection gap between the upper tower end cylinder 3 and the lower tower end cylinder 4 and the cylinder 1 is sealed. The entire tower body is placed between the two support columns 903 of the mounting frame 9. By rotating the hexagonal rotating head 1201 of multiple connecting screws 12, the first threaded end sleeve 102 on the side of the cylinder 1 at the end of the connecting screws 12 are threaded together to fix the entire tower body. By rotating the rotating handle at the end of the rotating screw 10, the two lifting guide seats 11 drive the entire tower body to move upward for installation.

[0037] Remove the first end cap 13, and introduce the adsorbent through the end pipe 301 inside the upper tower end cylinder 3. Then, it falls sequentially along the second connecting pipe 8, the distribution pipe 602 of the distributor 6 near the top inside the cylinder 1, and the first connecting pipe 7 into the distribution pipe 602 of the distributor 6 near the bottom inside the cylinder 1. Under the action of the second end cap 14, the adsorbent enters the cavity 601 through the inlet hole 605 on the circumferential side of the distribution pipe 602. When the distributor 6 near the bottom inside the cylinder 1 is full, the adsorbent fills the first connecting pipe 7 and fills the distributor 6 near the top inside the cylinder 1. When replacing the adsorbent in the distributor 6, simply remove the two third end caps 15 that are threaded to the circumferential side of the distributor 6, so that the adsorbent in the cavity inside the distributor 6 can be discharged through the threaded discharge hole 606, making it convenient to replace the adsorbent in the distributor 6.

[0038] Compressed air enters the tower body through the inlet of the upper tower end cylinder 3. Under the action of the reflux guide plate 302 on the side of the end pipe 301, it diffuses to the surroundings and is transmitted downward. Two conical distributors 6 further reduce the downward flow of compressed air and discharge it through the exhaust port at the bottom of the lower tower end cylinder 4, ensuring that the adsorbent fully dries the compressed air as it passes through the two distributors 6.
