Technical Field

[0001] The utility model belongs to the technical field of gas path purification of cutting gas, and in particular relates to a gas path purification device for a laser cutting machine. Background Art

[0002] Laser cutting gas purifier plays a vital role in the laser cutting process. Its core function is to remove impurities, oil, moisture and other potential pollutants in the cutting gas or auxiliary gas to ensure that the gas quality reaches the best state when supplying gases such as oxygen, nitrogen or compressed air to the laser cutting machine. By ensuring the cleanliness and dryness of the gas, it not only helps to improve the accuracy and stability of laser cutting, but also effectively prolongs the service life of the laser cutting equipment.

[0003] However, during operation, current gas purification devices mainly rely on internal filter elements to clean and dry the gas. This reliance makes the replacement frequency of the filter element relatively high, increasing maintenance costs and operational complexity. At the same time, the discharge of liquid pollutants is also cumbersome and difficult, which brings certain inconveniences to users.

[0004] Therefore, it is very necessary to invent a gas path purification device for a laser cutting machine. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a gas path purification device for a laser cutting machine, comprising a gas path purification tank, a gas path connection top cover, a drain bolt and a purification filter element, wherein the gas path connection top cover is sealed and fixedly installed on the top of the gas path purification tank, and the drain bolt is meshed and sealedly installed on the bottom thereof; the purification filter element is installed inside the gas path purification tank and the connection top cover;

[0006] The gas path purification tank comprises a tank body, a drain port, a fixed column, a drain valve plate and a tray. The gas path connection top cover is sealed and fixedly installed on the top of the tank body, and the drain port arranged below it is meshed and sealed with the drain bolt; the lower end of the fixed column is fixedly connected to the inside of the tank body, the drain valve plate and the tray are fixedly installed on the fixed column, and the purification filter element is arranged above the tray;

[0007] The gas path connection top cover includes a connection external body, a sealing cover, a sealing sleeve, a pipe opening and a connecting cavity. The sealing cover is fixedly installed in the middle of the connection external body, and the sealing cover is sealed and fixedly connected to the top of the tank body; the sealing sleeve is integrally arranged inside the sealing cover, and the upper end sleeve of the purification filter element is arranged on the inner side of the sealing sleeve; two pipe openings are arranged on the connection external body, and the two pipe openings are respectively connected to the connecting cavity and the inner side of the sealing sleeve.

[0008] Preferably, the branch portion at the lower end of the fixed column is fixedly connected to the inner wall of the tank body, the purification filter element is sleeved on the outside of the fixed column, and there is a spiral linear flow distance between the purification filter element and the inner wall of the tank body for gas.

[0009] Preferably, the cross-section of the drain valve plate fixedly installed on the fixed column is an inverted "V"-shaped structure, the material used for the drain valve plate is spring steel, the area below the drain valve plate is a water storage area, which is below the interior of the tank body, and the area is also connected to the drain port.

[0010] Preferably, there is a spiral linear flow interval of gas between the sealing cover and the sealing sleeve, and the sealing cover is tangentially connected to the connecting cavity arranged inside the external connecting body.

[0011] Preferably, the external connecting body is provided with two pipe openings, namely an air injection pipe opening and an exhaust pipe opening, wherein the air injection pipe opening is connected to the connecting cavity provided inside the external connecting body, and the exhaust pipe opening passes through the sealing sleeve and is connected to the inner side thereof.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The innovation of the utility model lies in the introduction of a uniquely designed gas path connection top cover, which cleverly guides the incoming gas into the gas path purification tank in a spiral flow pattern. This flow pattern greatly enhances the contact area and contact time between the gas and the tank wall and the purification filter element. This spiral flow not only gives the liquid and dust particles in the gas more opportunities to collide with and adhere to the tank wall and the filter element, but also keeps the gas in close contact with the tank wall throughout the purification process, thereby significantly reducing the risk of these pollutants entering the subsequent system through the filter element and effectively reducing the filtering burden of the filter element.

[0014] In addition, the ingenious design of the internal structure of the gas purification tank enables the change in pressure inside the tank to force the drain valve to open during the gas flow process. This mechanism causes liquid pollutants such as grease and water attached to the tank wall and filter element to accumulate downward, making it easier to clean up later. At the same time, the clever combination of the drain port and the drain bolt makes the discharge of water simple and quick, greatly reducing the maintenance complexity and workload of the equipment and improving the overall convenience and efficiency of use.

[0022] As attached Figure 1 To Attachment Figure 3 As shown:

[0023] The utility model provides an air path purification device for a laser cutting machine, comprising an air path purification tank 1, an air path connection top cover 2, a drain bolt 3 and a purification filter element 4. The air path connection top cover 2 is sealed and fixedly installed on the top of the air path purification tank 1, and the drain bolt 3 is meshingly and sealably installed on the bottom thereof; the purification filter element 4 is installed inside the air path purification tank 1 and the connection top cover 2.

[0024] The gas path purification tank 1 includes a tank body 11, a drain port 12, a fixed column 13, a drain valve plate 14 and a tray 15. The gas path connection top cover 2 is sealed and fixedly installed on the top of the tank body 11, and the drain port 12 arranged below it is meshed and sealed with the drain bolt 3; the lower end of the fixed column 13 is fixedly connected to the inside of the tank body 11, and the drain valve plate 14 and the tray 15 are fixedly installed on the fixed column 13, and the purification filter element 4 is arranged above the tray 15. The gas path purification tank 1 allows the change in pressure in the tank to force the drain valve plate 14 to open during the gas flow process. This mechanism causes liquid pollutants such as grease and water attached to the tank wall and the purification filter element 4 to accumulate downward, which is convenient for subsequent cleaning.

[0025] The gas circuit connection top cover 2 includes a connection external body 21, a sealing cover 22, a sealing sleeve 23, a pipe port 24 and a connecting cavity 25. The sealing cover 22 is fixedly installed in the middle of the connection external body 21, and the sealing cover 22 is sealed and fixedly connected to the top of the tank body 11; the sealing sleeve 23 is integrally arranged inside the sealing cover 22, and the upper end sleeve of the purification filter element 4 is arranged inside the sealing sleeve 23; two pipe ports 24 are arranged on the connection external body 21, and the two pipe ports 24 are respectively connected to the connecting cavity 25 and the inner side of the sealing sleeve 23. The gas circuit connection top cover 2 cleverly guides the incoming gas to enter the gas circuit purification tank 1 in a spiral flow pattern, and this flow pattern greatly enhances the contact area and contact time between the gas and the inner wall and the purification filter element 4. Embodiment 1:

[0026] Specifically, the branch at the lower end of the fixed column 13 is fixedly connected to the inner wall of the tank body 11, ensuring the stability and firmness of the column. The purification filter element 4 is cleverly placed on the outside of the fixed column 13. This design not only facilitates the installation and disassembly of the filter element, but also ensures the stability and efficiency of the filter element during the purification process. A certain space is deliberately left between the purification filter element 4 and the inner wall of the tank body 11, and this space allows the gas to flow in a spiral linear flow pattern. This spiral linear flow pattern not only increases the contact area between the gas and the tank wall and the purification filter element, but also prolongs the residence time of the gas during the purification process. Such a design can ensure that impurities, oil stains, moisture and other pollutants in the gas have more opportunities to contact and adhere to the tank wall and the filter element before passing through the purification filter element, thereby improving the purification effect and efficiency.

[0027] Specifically, the cross-section of the drain valve plate 14 fixedly installed on the fixed column 13 is an inverted "V"-shaped structure, and the material used for the drain valve plate 14 is spring steel, so that during the gas flow process, the liquid will naturally flow to the bottom of the "V" due to gravity, that is, the area below the drain valve plate 14. This design ensures that the liquid can be effectively collected and gathered, and will not be randomly scattered inside the tank body 11. The area below the drain valve plate 14 is designed as a water storage area. This area is located at the bottom of the tank body 11 and is connected to the drain port 12. When the internal pressure of the tank body 11 reaches a certain level, the drain valve plate 14 will be opened by pressure, flowing into the water storage area for storage, and the subsequent liquid will be discharged through the drain port 12. This design ensures that the liquid can be discharged in a timely and effective manner, and avoids excessive accumulation of liquid inside the tank body 11, which affects the purification effect and equipment performance.

[0028] Specifically, a certain space is reserved between the sealing cover 22 and the sealing sleeve 23, and this space allows the gas to flow in a spiral linear manner. This flow pattern not only increases the contact area between the gas and the sealing cover 22 and the sealing sleeve 23, but also prolongs the residence time of the gas during the purification process. This helps the impurities, oil stains, moisture and other pollutants in the gas to fully contact with the purification material, thereby improving the purification effect. At the same time, the sealing cover 22 is tangentially connected to the connecting cavity 25 set inside the external body 21. This design ensures that the gas can smoothly enter the gas path purification tank 1 and continue to flow along the spiral linear path. The tangentially connected design reduces the resistance of the gas and improves the flow efficiency of the gas, thereby ensuring the overall performance of the purifier.

[0029] Specifically, the external connecting body 21 is provided with two pipe openings 24, namely an air injection pipe opening and an exhaust pipe opening, wherein the air injection pipe opening is connected to the connecting cavity 25 provided inside the external connecting body 21, and the exhaust pipe opening passes through the sealing sleeve 23 and is connected to the inner side thereof. Embodiment 2:

[0030] First, the gas enters the device through the gas injection port on the top cover 2 through the gas path. After the gas enters the connecting cavity 25 connected to the external body 21, the gas flows in a spiral linear manner due to the reserved space design between the sealing cover 22 and the sealing sleeve 23. This flow pattern greatly increases the contact area between the gas and the sealing cover 22 and the sealing sleeve 23, and prolongs the residence time of the gas during the purification process, which helps the impurities, oil stains, moisture and other pollutants in the gas to fully contact with the purification material.

[0031] Then, the gas enters the gas path purification tank 1. In the gas path purification tank 1, the gas continues to pass through the space between the purification filter element 4 and the inner wall of the tank body 11 in a spiral linear flow pattern. This design ensures that the pollutants in the gas have more opportunities to contact and adhere to the tank wall and the purification filter element 4. At the same time, the purification filter element 4 is sleeved on the outside of the fixed column 13, ensuring the stability and efficiency of the filter element during the purification process.

[0032] During the gas flow, due to the change in pressure in the tank, the drain valve plate 14 installed on the fixed column 13 will be opened by pressure. The cross-section of the drain valve plate 14 is an inverted "V"-shaped structure, and the material is spring steel, so that the liquid will naturally flow to the bottom of the "V" due to gravity, that is, the area below the drain valve plate 14. This area is designed as a water storage area and is connected to the drain port 12. When the liquid accumulates to a certain extent, the liquid can be discharged from the drain port 12 by unscrewing the drain bolt 3, avoiding excessive accumulation of liquid inside the tank body 11 and affecting the purification effect and equipment performance.

[0033] Finally, the gas filtered by the purification filter element 4 is discharged through the exhaust pipe port, completing the entire purification process. The entire device achieves effective purification of impurities, oil, water and other pollutants in the gas path of the laser cutting machine and timely discharge of liquid through the spiral linear flow pattern, the efficient filtration of the purification filter element 4 and the automatic drainage function of the drain valve plate 14, ensuring the stable and efficient operation of the laser cutting machine.

[0034] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
