Description

Technical Field

[0001] This utility model relates to the technical field of gas purification devices, specifically an electronic-grade oxygen purification device. Background Technology

[0002] Currently, traditional PSA molecular sieve oxygen generators are limited by process technology, and the oxygen purity can only reach 93%-95%, which cannot meet the higher level of demand. They can only rely on cryogenic processes to further improve the oxygen purity and produce pure oxygen to meet the high-purity oxygen needs of industries such as metallurgy, medical care, and environmental protection.

[0003] According to a public disclosure of an oxygen purification device (publication number: CN220918646U), the device includes an adsorption tower assembly, valve group pipeline, control components, and an electrical control box within a housing. The adsorption tower assembly comprises a left adsorption tower and a right adsorption tower. The left adsorption tower is formed by connecting a first adsorption tower and a second adsorption tower in series, with the outlet of the first adsorption tower connected to the inlet of the second adsorption tower. The right adsorption tower is formed by connecting a third adsorption tower and a fourth adsorption tower in series, with the outlet of the third adsorption tower connected to the inlet of the fourth adsorption tower. A valve group pipeline is provided between the left and right adsorption towers, and several pneumatic valves, check valves, and solenoid valves are installed on the valve group pipeline. Through optimized and improved design of the utility model product, low-purity oxygen can be produced into high-purity oxygen with a finished gas purity of 99% or higher without cryogenic process equipment. Compared with cryogenic equipment, it has higher reliability and controllability, and lower operating costs, thereby achieving the technical effects of improving production efficiency, reducing energy consumption, and saving costs.

[0004] In the aforementioned application, the pipeline of the purification device cannot be coated by the cooperation between the valve group pipeline and the pneumatic valve assembly. When used for a long time, the pipeline is prone to aging and damage, and oxygen leakage may lead to explosions and other hazards. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an electronic-grade oxygen purification device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electronic-grade oxygen purification device, comprising a base plate, a purification device fixedly connected to the top of the base plate, a detector disposed on the side of the purification device, and a coating device disposed on the top of the base plate;

[0007] The coating device includes a motor mounted above a base plate. A bracket is fixedly connected to the top of the base plate. The side of the motor is fixedly connected to the side of the bracket. A threaded rod is fixedly connected to the output shaft of the motor. A limit rod is rotatably connected inside the bracket. A threaded sleeve is threadedly connected to the circumference of the threaded rod. A connecting frame is fixedly connected to the circumference of the threaded sleeve. A brush plate is fixedly connected to the side of the connecting frame. A brush strip is fixedly connected to the side of the brush plate. A paint tank is fixedly connected to the top of the bracket. The paint tank has an inlet at the top and an outlet at the side. A conveying pipe is fixedly connected to the side of the paint tank.

[0008] As mentioned above, a groove is provided on the side of the paint box, and a slider is slidably connected inside the groove. The discharge port is opened or closed by sliding the slider.

[0009] As described above, the feed pipe is located above the brush bar, and the limiting rod is located on the displacement trajectory of the threaded sleeve. When the outlet is opened, the paint in the paint box flows onto the brush bar through the feed pipe.

[0010] As described above, an air intake device is provided on the top of the base plate. The air intake device includes a fan frame, and a rotating shaft is rotatably connected inside the fan frame. A first belt groove is formed on the circumferential surface of the threaded rod, and a second belt groove is formed on the circumferential surface of the rotating shaft. A belt is driven to the circumferential surface of the first belt groove, and the inner side of the belt is on the circumferential surface of the second belt groove. Blades are fixedly connected to the circumferential surface of the rotating shaft. Through the transmission of the belt, the threaded rod rotates, driving the rotating shaft to rotate. When the rotating shaft rotates, the blades blow air into the purification device.

[0011] The aforementioned number of blades is set to six, and they are arranged in a circumferential array on the circumferential surface of the rotating shaft. The multiple blades improve the blowing effect.

[0012] Compared with existing technologies, this electronic-grade oxygen purification device has the following advantages:

[0013] I. This utility model achieves coating by cooperating with components such as the motor, bracket, threaded rod, limiting rod, threaded sleeve, and connecting frame inside the coating device. When coating is required, the slider is first slid to open the discharge port. When the discharge port is open, the paint in the paint tank flows onto the brush strip through the conveying pipe. Then, the motor is started. When the motor starts, the threaded rod rotates, causing the threaded sleeve to move left and right. When the threaded sleeve moves, the connecting frame on the threaded sleeve moves. When the connecting frame moves, the brush strip on the brush plate coats the tube, thus achieving the coating effect.

[0014] II. This utility model achieves a uniform air intake effect by cooperating with components such as the fan frame, rotating shaft, belt, and blades inside the air intake device. When the motor starts, the belt drives the threaded rod to rotate, which in turn drives the rotating shaft. When the rotating shaft rotates, the blades on the shaft draw air into the purification device at a uniform speed.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-6 As shown, this utility model provides a technical solution: an electronic-grade oxygen purification device, including a base plate 1, a purification device 2 fixedly connected to the top of the base plate 1, a detector 3 provided on the side of the purification device 2, and a coating device 4 provided on the top of the base plate 1.

[0025] The coating device 4 includes a motor 41, which is mounted above the base plate 1. A bracket 42 is fixedly connected to the top of the base plate 1. The side of the motor 41 is fixedly connected to the side of the bracket 42. A threaded rod 43 is fixedly connected to the output shaft of the motor 41. A limit rod 44 is rotatably connected inside the bracket 42. A threaded sleeve 45 is threadedly connected to the circumference of the threaded rod 43. A connecting frame 46 is fixedly connected to the circumference of the threaded sleeve 45. A brush plate 47 is fixedly connected to the side of the connecting frame 46. A brush strip 48 is fixedly connected to the side of the brush plate 47. A paint tank 49 is fixedly connected to the top of the bracket 42. An inlet 410 is opened at the top of the paint tank 49. An outlet 411 is opened on the side of the paint tank 49. A conveying pipe 412 is fixedly connected to the side of the paint tank 49.

[0026] The side of the paint tank 49 is provided with a groove 413, and a slider 414 is slidably connected inside the groove 413. The discharge port 411 is opened or closed by sliding the slider 414.

[0027] The feed pipe 412 is located above the brush strip 48, and the limiting rod 44 is located on the displacement trajectory of the threaded sleeve 45. When the discharge port 411 is opened, the paint in the paint box 49 flows onto the brush strip 48 through the feed pipe 412.

[0028] During long-term use, in order to prevent damage to the pipes of the purification device 2 and cause harm, it is necessary to coat the pipes. First, slide the slider 414 so that the paint in the paint tank 49 flows onto the brush strip 48 through the feed pipe 412. Then start the motor 41. When the motor 41 starts, the threaded rod 43 on the output shaft of the motor 41 rotates clockwise. When the threaded rod 43 rotates clockwise, the threaded sleeve 45 on the threaded rod 43 moves horizontally to the left. When the threaded sleeve 45 moves horizontally to the left, the connecting frame 46 on the threaded sleeve 45 moves horizontally to the left. When the connecting frame 46 moves horizontally to the left, the brush strip 48 on the brush plate 47 on the side of the connecting frame 46 coats the pipe. When the threaded rod 43 rotates counterclockwise, the threaded sleeve 45 on the threaded rod 43 moves horizontally to the right. When the threaded sleeve 45 moves horizontally to the right, the connecting frame 46 on the threaded sleeve 45 moves horizontally to the right. When the connecting frame 46 moves horizontally to the right, the brush strip 48 on the brush plate 47 on the side of the connecting frame 46 coats the pipe.

[0029] An air intake device 5 is provided on the top of the base plate 1. The air intake device 5 includes a fan frame 51. A rotating shaft 52 is rotatably connected inside the fan frame 51. A first belt groove 53 is opened on the circumferential surface of the threaded rod 43. A second belt groove 54 is opened on the circumferential surface of the rotating shaft 52. A belt 55 is drivenly connected to the circumferential surface of the first belt groove 53. The inner side of the belt 55 is on the circumferential surface of the second belt groove 54. A blade 56 is fixedly connected to the circumferential surface of the rotating shaft 52. Through the transmission of the belt 55, the threaded rod 43 rotates, driving the rotating shaft 52 to rotate. When the rotating shaft 52 rotates, the blade 56 blows air into the purification device 2.

[0030] The number of blades 56 is set to six, and they are arranged in a circumferential array on the circumferential surface of the rotating shaft 52. The multiple blades 56 improve the blowing effect.

[0031] A method of using an electronic-grade oxygen purification device includes the following steps:

[0032] S1: In order to prevent the pipes of the purification device 2 from being damaged and causing harm, it is necessary to coat the pipes. First, slide the slider 414 and the brush strip 48 on the side brush plate 47 of the connecting frame 46 coats the pipes.

[0033] S2: To prevent the gas from entering slowly and affecting purification, the gas needs to enter the purification device 2 at a uniform speed. First, start the motor 41. The blades 56 on the rotating shaft 52 cannot blow air into the purification device 2.

[0034] The motor 41 and shaft 52 in S2 are set as DC12V DC motor and ShaftA shaft, respectively.

[0035] When gas enters the purification device 2, in order to prevent the gas from entering slowly and affecting the purification process, the gas needs to enter the purification device 2 at a uniform speed. First, the motor 41 is started. When the motor 41 starts, the threaded rod 43 on the output shaft of the motor 41 rotates clockwise. When the threaded rod 43 rotates clockwise, it drives the rotating shaft 52 to rotate clockwise through the transmission of the belt 55. When the rotating shaft 52 rotates clockwise, the blades 56 on the rotating shaft 52 blow air into the purification device 2. When the threaded rod 43 rotates counterclockwise, it drives the rotating shaft 52 to rotate counterclockwise through the transmission of the belt 55. When the rotating shaft 52 rotates counterclockwise, the blades 56 on the rotating shaft 52 cannot blow air into the purification device 2.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
