Description

Technical Field

[0001] This invention relates to the field of compressed air purification technology, and in particular to an air purifier wastewater discharge system. Background Technology

[0002] As a core process device supplying dry and clean compressed air to instruments, air springs, pneumatic valves, braking systems, clamping systems, medical devices, food production equipment, and other applications, compressed air purification units are widely used in various types of industrial equipment. The drain valve, as a key component of a small compressed air purification unit, is located at the front end of the unit. Its performance and reliability directly affect whether the air quality entering the compressed air purification unit meets design requirements.

[0003] Traditional drain valves are large and heavy, making it difficult to miniaturize compressed air purification devices. Furthermore, the inlet location doesn't allow for convenient automatic on / off control, hindering the miniaturization and integration of purification devices. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an air purifier sewage discharge system that is small and compact in structure and can meet the needs of miniaturization and integration of purification devices.

An electromagnetic drive mechanism is mounted on the drain valve seat and located within a C-shaped notch in the base. The electromagnetic drive mechanism includes a stationary iron core, a moving iron core, and an electromagnetic coil. All three are arranged along the axis of the drain valve seat. The electromagnetic coil is located outside the stationary and moving iron cores. The moving iron core is movably mounted on the stationary iron core and connected to it via a spring. By controlling the energization and de-energization of the electromagnetic coil, the rising and falling of the moving iron core is controlled. When the moving iron core rises, the drain chamber is connected to the drain channel; when the moving iron core falls, the connection between the drain chamber and the drain channel is blocked by the moving iron core.

[0006] The air purifier exhaust system according to embodiments of the present invention has at least the following advantages: Since both the exhaust valve seat and the electromagnetic drive mechanism are located within a C-shaped notch, and the exhaust valve seat body is machined from the base of a small compressed air purification device, while other components such as the valve core are attached to the base of the small compressed air purification device, the air purifier exhaust system is compact and small overall, meeting the miniaturization requirements of compressed air purification devices. The exhaust channel is connected to the exhaust chamber via an exhaust flow channel. By controlling the energization and de-energization of the electromagnetic coil, the connection and disconnection between the exhaust channel and the exhaust chamber can be achieved, thereby enabling program-controlled automatic switching functions and meeting customer demands for miniaturization and integration of the purification device.

[0007] According to some embodiments of the present invention, a boss is provided at the upper end of the drain valve seat, the boss is arranged along the axis of the drain valve seat, the drain channel passes through the boss, and the boss abuts against the moving iron core.

[0008] According to some embodiments of the present invention, when the moving iron core rises, the gap between the moving iron core and the boss is smaller than the diameter of the sewage channel.

[0031] refer to Figures 1 to 4 An air purifier exhaust system according to an embodiment of the present invention is described.

[0032] like Figures 1 to 4 As shown, the air purifier drainage system according to an embodiment of the present invention includes: a base 100, a C-shaped notch 110 on the base 100, a drainage chamber 120 inside the base 100, and a downwardly inclined drainage channel 130 connected to the lower end of the drainage chamber 120; a drainage valve seat 200, which is mounted on the base 100, and a drainage channel 210 is provided inside the drainage valve seat 200 along the axial direction, and the drainage chamber 120 is connected to the drainage channel 210 through the drainage channel 130. An electromagnetic drive mechanism 300 is mounted on the drain valve seat 200 and located within the C-shaped notch 110 of the base 100. The electromagnetic drive mechanism 300 includes a stationary iron core 310, a moving iron core 340, and an electromagnetic coil 350. The stationary iron core 310, the moving iron core 340, and the electromagnetic coil 350 are all arranged along the axis of the drain valve seat 200. The electromagnetic coil 350 is located outside the stationary iron core 310 and the moving iron core 340. The moving iron core 340 is movably mounted on the stationary iron core 310. The moving iron core 340 is connected to the stationary iron core 310 via a spring 360. The rising and falling of the moving iron core 340 is controlled by controlling the energization and de-energization of the electromagnetic coil 350. When the moving iron core 340 rises, the sewage discharge chamber 120 is connected to the sewage discharge channel 210. When the moving iron core 340 falls, the connection between the sewage discharge chamber 120 and the sewage discharge channel 210 is blocked by the moving iron core 340.

[0033] like Figures 1 to 4As shown, a C-shaped notch 110 is provided on the left side of the base 100. The drain valve seat 200 is installed on the C-shaped notch 110. An electromagnetic drive mechanism 300 is installed on the upper end of the drain valve seat 200. The electromagnetic drive mechanism 300 is located inside the C-shaped notch 110. The electromagnetic drive mechanism 300 is used to switch the communication state between the drain channel 210 in the drain valve seat 200 and the drain cavity 120 in the base 100. Since both the drain valve seat 200 and the electromagnetic drive mechanism 300 are located inside the C-shaped notch 110, and the drain valve seat 200 body is machined from the base 100 of the small compressed air purifier, and other components such as the valve core are attached to the base 100 of the small compressed air purifier, the air purifier drain system is small and compact, which is suitable for the miniaturization requirements of compressed air purifiers. The sewage discharge channel 210 is connected to the sewage discharge chamber 120 through the sewage discharge channel 130. By controlling the energization and de-energization of the electromagnetic coil 350, the connection and disconnection between the sewage discharge channel 210 and the sewage discharge chamber 120 can be realized, thereby completing the program-controlled automatic switching function and meeting the customer's demand for miniaturization and integration of the purification device.

[0034] like Figures 1 to 4 As shown, a boss 220 is provided at the upper end of the drain valve seat 200. The boss 220 is arranged along the axis of the drain valve seat 200, and the drain channel 210 passes through the boss 220. The boss 220 abuts against the moving iron core 340. When the electromagnetic coil 350 is energized, the moving iron core 340 is attracted upward by electromagnetic force, and a gap is created between the moving iron core 340 and the upper surface of the boss. This gap connects the drain channel 210 with the drain flow channel 130 and the drain chamber 120. The high-pressure gas in the drain chamber 120 drives the sewage to flow along the downward-sloping drain flow channel 130, and enters the drain channel 210 through the gap between the moving iron core 340 and the upper surface of the boss, and is discharged along the drain channel 210. When the electromagnetic coil 350 is de-energized, the moving iron core 340 is reset by the spring force of the spring 360 and moves downward. The moving iron core 340 closes the drain channel 210 on the drain valve seat 200, and the draining action stops. The height of the cone-shaped part 220 of the boss on the drain valve seat 200, together with the base 100, forms a small annular liquid accumulation groove close to the drain channel 210, which effectively improves the draining efficiency.

[0035] like Figure 2 As shown, when the moving iron core 340 rises, the gap K between the moving iron core 340 and the boss portion 220 is smaller than the diameter D of the drain channel 210. Therefore, debris cannot enter the drain channel 210, effectively preventing blockage.

[0036] like Figures 1 to 4As shown, the electromagnetic drive mechanism 300 includes a sealing gasket 370, which is annular and coaxially arranged with the drain valve seat 200. The sealing gasket 370 is positioned between the drain valve seat 200 and the stationary iron core 310. A filter screen 140 is laid at the bottom of the drain chamber 120. It also includes a first sealing ring 230, which is positioned between the base 100 and the drain valve seat 200. The sealing gasket 370 and the first sealing ring 230 prevent sewage leakage, ensuring the airtightness and reliability of the drain system.

[0037] like Figures 1 to 4 As shown, the air purifier's wastewater discharge system also includes a heating mechanism 400, which is mounted on the base 100 and located below the wastewater discharge channel 130. The heating mechanism 400 heats the wastewater discharge channel 130 to prevent it from freezing and clogging. The heating mechanism 400 includes a heating element 410 and a heating cover plate 420. The heating element 410 is disposed within the base 100, and the heating cover plate 420 covers the base 100. The heating cover plate 420 is connected to the base 100 by bolts 430. Tightening the bolts 430 presses the heating element 410 firmly within the base 100. A second sealing ring 440 is provided between the heating cover plate 420 and the base 100. When the room temperature is higher than the activation setting value of the heating element 410, the heating element 410 is de-energized and does not operate. When the room temperature is lower than the start-up setting value of the heating element 410, the heating element 410 is powered on and starts working. The heating power is greater than the heat dissipation power. At this time, the drain channel 130 on the upper part of the heating element 410 is heated and the temperature rises, thereby effectively preventing ice from blocking the drain channel 210.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
