Description

Technical Field

[0001] This utility model relates to the field of industrial oxygen production technology, specifically to an air filter for an industrial oxygen generator. Background Technology

[0002] Industrial oxygen production utilizes air separation to produce large quantities of oxygen. Raw materials are widely available, and the use of physical properties reduces production costs. To improve conversion efficiency, industrial oxygen production equipment is typically placed in high mountains or areas with extensive forest cover. Air collection devices connected to these equipment are piped to areas with higher oxygen content deep in the mountains. However, industrial oxygen production equipment requires a large airflow rate. Current air filtration devices have reduced efficiency per second, necessitating a reduction in filtration efficiency to increase the intake airflow. Furthermore, in deep mountain environments, filters need frequent cleaning and replacement after a period of use to maintain filtration efficiency. Additionally, the presence of wild animals in these environments can damage the equipment, causing air filtration devices to fail and preventing the filtering of impurities. Damage to these devices can also allow smaller animals to enter the air ducts and then the oxygen production equipment, causing further damage. Utility Model Content

Detailed Implementation

[0030] 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.

[0031] Please see Figure 1-9This utility model provides a technical solution: an air filter for an industrial oxygen generator, including a protective device and a filter device 21 installed within the protective device. The protective device includes a cement base 16 fixedly installed on the mountainside, a metal frame installed on the cement base 16, and a filter mounting mechanism installed on the metal frame. The metal frame includes a 7-shaped support rod and reinforcing rods 17 at the bottom of the support rod. The bottom of the vertical end of the support rod is fixedly connected to the cement base 16. At least three reinforcing rods 17 are provided, and both ends of each reinforcing rod 17 are connected to the support rod and the cement base, respectively. All of them form a triangular structure between the vertical end of the support rod and the cement base surface. The horizontal far end of the support rod is provided with a vertically downward fixed rod 18. The filter installation mechanism is installed at the lower end of the fixed rod 18. The filter installation mechanism includes a fixed frame and a steel mesh 19. The six sides of the fixed frame are covered with steel mesh 19. The upper surface of the fixed frame is connected at four diagonals to form an X-shaped fixed frame 20. The center of the X-shaped fixed frame 20 is welded and fixed to the lower end of the fixed rod 18. The filter device 21 is set in the fixed frame. The air outlet of the filter device 21 is connected to the air inlet of the industrial oxygen production equipment through a steel pipe.

[0032] In practical applications, the fixed frame and the fixed rod 18 are connected by bolts, and the filter device 21 is fixedly installed in the fixed frame. Then, the filter is connected to the industrial oxygen generator through the steel pipe. During use, the steel mesh 19 can prevent animals from damaging the filter device 21. At the same time, the steel mesh 19 can first filter large particles such as leaves from the outside.

[0033] The filtration device 21 includes an output pipe 1, an input pipe 2, a connecting structure 3, and a filtration mechanism 4. Multiple input pipes 2 are evenly arranged in a horizontal and vertical configuration, and all input pipes 2 are interconnected to form a grid pattern. A connecting structure 3 is provided at each intersection point of the input pipes 2. The connecting structure 3 includes a connecting pipe 5 and a spring 6. The upper end of the connecting pipe 5 is fixedly connected to and communicates with the inside of the input pipe 2. The spring 6 is installed inside the connecting pipe 5, located at the end of the connecting pipe 5 closest to the input pipe 2, with its upper end abutting against the outer wall of the input pipe 2. An inverted J-shaped return groove 7 is provided on the lower side of the connecting pipe 5, and two inverted J-shaped return grooves 7 are symmetrically arranged on the connecting pipe 5. Each connecting pipe 5 is provided with a filtration structure. The connecting end of the filtration mechanism 4 is fixed to the connecting pipe 5 by the J-shaped return groove.

[0034] The input pipe 2 is structured in a grid pattern, with a filter mechanism 4 set at each node. All filter mechanisms 4 are interconnected, and all filter mechanisms 4 filter the air simultaneously, increasing the airflow of the filtered air output from the output pipe 1. Furthermore, when the filtration efficiency of some filter mechanisms 4 decreases, the interconnection between the output pipe 1 and the input pipe 2 allows other normal filters to continue filtering the air.

[0035] In a further specific implementation, in order to facilitate the installation efficiency between equipment, the vertical end of the support rod is divided into a rod body 22 and a cylinder body 23 that cooperate with each other. The upper end of the rod body 22 is integrally set with the horizontal end of the support rod. The cylinder body 23 is installed on the cement seat 16. The reinforcing rod 17 is fixedly connected to the cylinder body 23. The inner diameter of the cylinder body 23 matches the rod diameter of the rod body 22.

[0036] First, weld the cylinder 23 and the reinforcing rod 17 together, and then fix them onto the cement base 16. At the same time, install the filter device 21 into the fixed frame, and then install the fixed frame onto the fixed rod 18. Finally, raise the support rod and insert it into the cylinder 23 so that the filter device 21 is located at a high position to prevent large animals from damaging the filter device 21. At the same time, the steel mesh 19 can also prevent small animals or birds from climbing onto the fixed frame and damaging the filter.

[0037] In a further specific implementation, in order to avoid corrosion of the cylinder 23 by the external bottom surface, both the rod 22 and the cylinder 23 are made of stainless steel, which can prevent external corrosion damage; at the same time, the fixing frame and the steel mesh 19 can also be made of stainless steel.

[0038] In a further specific implementation, in order to facilitate the installation of the filter device 21, the fixing frame includes an upper frame 24 and a placement frame 25 with an upper opening. The X-shaped fixing bracket 20 is fixedly installed on the upper frame 24. The upper frame 24 and the placement frame 25 are fastened together by bolts. By setting the upper frame 24 and the placement frame 25 separately, it is convenient to insert and install the filter device 21, as well as to disassemble and maintain it later.

[0039] The upper inner side of the placement frame 25 is provided with a downward-facing sliding groove 27. Multiple sliding grooves 27 are evenly distributed. A through hole is provided on the side wall of the placement frame 25 corresponding to each sliding groove 27. A guide post is provided on the outermost side of the grid shape formed by the input pipes 2 corresponding to each sliding groove 27. The outer end of the guide post is provided with a threaded hole that communicates with the through hole.

[0040] After the filter device 21 is placed into the placement frame 25, the fixing column 28 is fitted to each slide groove 27, and then fixed with bolts.

[0041] In a further specific implementation, in order to facilitate the overall installation of the equipment and subsequent disassembly and maintenance, a vertically installed air outlet pipe 26 is provided on the upper frame 24. The lower end of the air outlet pipe 26 is located inside the placement frame 25, and the upper end of the air outlet pipe 26 is located above the upper surface of the upper frame 24. Sealing rings are respectively provided on the outer circumferential side of the upper and lower ends of the air outlet pipe 26. The upper end of the air outlet pipe 26 can extend into the pipe port connected to the air inlet of the industrial oxygen generator, and the lower end of the air outlet pipe 26 can extend into the air outlet of the filter device 21 installed in the placement frame 25.

[0042] In this technical solution, the air outlet pipe 26 is welded to the upper frame 24. After the filter device 21 is installed and fixed inside the placement frame 25, the position of the pipe at the air outlet end of the filter device 21 is adjusted to match the position of the air outlet pipe 26. Then, the upper frame 24 is installed on the placement frame 25, and the lower end of the air outlet pipe 26 is inserted into the adjusted pipe at the air outlet end of the filter device 21 and sealed by the sealing ring on the air outlet pipe 26. After the matching is completed, the upper frame 24 and the placement frame 25 are fixed with bolts. Finally, the support rod is erected and inserted into the cylinder 23, so that the filter device 21 is located at a high position to avoid large animals from damaging the filter device 21. At the same time, the steel mesh 19 can also prevent small animals or birds from climbing onto the fixed frame and damaging the filter. Then, the external steel pipe is matched with the upper end of the air outlet pipe 26 to form a complete air passage.

[0043] When disassembly and maintenance are required, pull the external pipe out of the air outlet pipe 26, and then pull the support rod 22 out of the cylinder 23. The support rod can then be laid down as a whole, and the fixing frame and filter device 21 can be cleaned and repaired.

[0044] The filtration mechanism 4 includes an air inlet pipe 8, a filter sponge 9, and a non-woven fabric filter screen 10. The upper end of the air inlet pipe 8 is provided with a sealing rubber ring 14. The upper end of the air inlet pipe 8 is placed inside the connecting pipe 5 and sealed to the side wall of the connecting pipe 5 by the sealing rubber ring 14. The lower end of the air inlet pipe 8 is set as a closed configuration. The upper end of the air inlet pipe 8 is provided with a matching limiting protrusion 11 corresponding to the inverted J-shaped return groove 7. Air inlet holes 15 are evenly distributed around the side of the air inlet pipe 8. The filter sponge 9 covers the side of the air inlet pipe 8 and covers all the air inlet holes 15. The non-woven fabric filter screen is located outside the filter sponge 9 and completely covers the filter sponge 9.

[0045] To improve the air intake efficiency of each air intake pipe 8, multiple air intake holes 15 are densely arranged on the side of the air intake pipe 8 to increase the air intake volume. At the same time, the filter sponge 9 and non-woven filter screen 10 can seal and filter all the air intake holes 15 to ensure that the incoming air filtration quality is consistent.

[0046] Limiting plates 12 are respectively provided on the upper and lower ends of the air intake pipe 8. The filter sponge 9 and the non-woven fabric filter screen are located between the two limiting plates 12. By setting the two limiting plates 12, the problem of the filter sponge 9 and the non-woven fabric filter screen 10 falling off the air intake pipe 8 after long-term use is avoided.

[0047] The limiting plate 12 at the lower end of the air intake pipe 8 is fixedly connected to the air intake pipe 8 by a thread. The limiting plate 12 at one end is detachable, which makes it convenient to disassemble and replace the filter sponge 9 and the non-woven filter screen 10.

[0048] The lower end of the air intake pipe 8 is threadedly sealed with a plug 13. When the filter mechanism 4 is in normal use, the lower end of the air intake hole 15 is sealed by the plug 13. When it is necessary to clean the inside of the air intake pipe 8, the plug 13 is removed, making it convenient for the cleaning device to extend into the air intake pipe 8 for cleaning.
