Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a water intake and drainage structure for preventing condensate backflow in an air compressor. Background Technology

[0002] Existing compressed air delivery systems often connect the outlets of multiple screw air compressors in parallel to a main duct with a large nominal diameter, and there is a significant vertical height difference between the main duct and several branch ducts. This common system structure makes it very easy for condensate to accumulate inside the main duct.

[0003] If the check valve of the air compressor has poor sealing performance, the condensate accumulated in the main air duct will backflow into the air compressor even when it is stopped due to the pressure difference. The intrusion of condensate can cause serious damage to the air compressor, the most prominent problem being the deterioration of the air compressor lubricating oil.

[0004] Although existing compressed air delivery systems typically include a drain valve on the main duct, current draining methods have significant limitations. Existing draining methods mainly rely on manual or timed draining, neither of which can completely remove condensate accumulated at the bottom of the pipes. Manual draining requires regular checks and operations by personnel, which is not only labor-intensive but also prone to human error leading to untimely or incomplete draining. While timed draining achieves some degree of automation, it cannot be flexibly adjusted according to actual condensate accumulation, resulting in incomplete draining as well. Furthermore, existing technologies often lack condensate vapor absorption devices, hindering the absorption and interception of condensate vapor. Utility Model Content

[0005] This invention provides a water intake and drainage structure for preventing condensate backflow in an air compressor, thereby solving the problems existing in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A water suction and drainage structure for preventing condensate backflow in an air compressor includes an air compressor connected to a duct. A U-shaped pipe section is provided near the air compressor. A water suction component is provided on the inner wall of the lower end of the U-shaped pipe section. The water suction component is connected to a drainage component and an adjustment component. The drainage assembly includes a water collection tank, which is connected to the U-shaped pipe section via a drain pipe. The bottom of the water collection tank has a water outlet, and the water outlet has a limiting groove. A fixing ring is fixedly connected in the limiting groove. One end of the fixing ring is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to a buoyancy ball. The buoyancy ball is in contact with the upper end of the water outlet.

[0007] The water-absorbing assembly includes a water-absorbing layer, a fixed mesh is fixedly connected to the water-absorbing layer, a water-collecting ring is fixedly sleeved on the outer ring of the fixed mesh, the water-collecting ring is rotatably connected to the inner wall of the lower end of the U-shaped pipe section through a rotating column, a water-collecting pipe is connected to the bottom of the water-collecting ring, the water-collecting pipe passes through the bottom rotating column and is fixedly connected to it and extends out of the bottom of the U-shaped pipe section.

[0008] The adjustment assembly includes a first bevel gear, a second bevel gear, and a motor. The first bevel gear is set on the outside of the water collection pipe and located between the U-shaped pipe and the water collection tank. The output end of the motor is fixedly connected to the second bevel gear, and the first bevel gear meshes with the second bevel gear.

[0009] Furthermore, the spring force is less than the buoyancy of the buoyancy ball.

[0010] Furthermore, the size of the water collection ring is consistent with the size of the inner wall at the lower end of the U-shaped pipe section.

[0011] Furthermore, the water collecting ring has a water collecting ring groove with a U-shaped cross-section.

[0012] Furthermore, the bottom of the water collection tank is designed to be conical.

[0013] Furthermore, the absorbent layer is configured as two layers, which are respectively fixed on the two surfaces of the fixing net.

[0014] This utility model has the following beneficial effects: (1) This utility model connects the water collection tank to the U-shaped pipe section, and discharges the condensate accumulated in the U-shaped pipe section into the water collection tank through the drain pipe. The water in the water collection tank is discharged through the outlet. At the same time, the water absorption layer is fixed on the fixed net and is fully wrapped by the water collection ring. The size of the water collection ring is consistent with the inner wall of the bottom of the U-shaped pipe section, which can fit tightly to ensure that the condensate is absorbed in all directions and thus absorbs and intercepts the condensate. The U-shaped water collection ring groove opened in the water collection ring further facilitates the collection of condensate. The water collection ring is rotatably connected to the inner wall of the bottom of the U-shaped pipe section through the rotating column. With the help of the adjustment component, the angle of the water absorption layer can be flexibly adjusted according to the working state of the air compressor. This realizes efficient condensate collection and flexible working state adjustment.

[0015] (2) The bottom of the water collection tank of this utility model is set in a conical shape, which facilitates the convergence of condensate to the outlet. The combination of the buoyancy ball, spring and fixing ring at the outlet forms an automatic drain valve. When the condensate in the water collection tank reaches a certain amount, the buoyancy of the buoyancy ball is greater than the spring force, the buoyancy ball rises and opens the outlet, and the condensate is automatically discharged; when the water volume decreases and the buoyancy is insufficient to overcome the spring force, the buoyancy ball falls back and closes the outlet to prevent air backflow.

[0016] (3) The present invention sets the water-absorbing layer as two layers, which are fixed on the two surfaces of the fixed net respectively, greatly increasing the water-absorbing area and water-absorbing capacity, and can absorb condensed water vapor more quickly and thoroughly, reducing the accumulation of condensed water in the air duct.

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Example 1

[0020] A water intake and drainage structure for preventing condensate backflow in an air compressor, as shown in the attached figure. Figure 1-5 As shown, it includes an air compressor 1, the air compressor 1 is connected to an air duct 2, the air duct 2 is provided with a U-shaped pipe section 3 near the air compressor 1, the lower end of the inner wall of the U-shaped pipe section 3 is provided with a water suction component, the water suction component is connected to a drainage component, and the water suction component is connected to an adjustment component. The drainage assembly includes a water collection tank 9, which is connected to the U-shaped pipe section 3 via a drain pipe 19. The drain pipe discharges the condensate accumulated in the U-shaped pipe section. The bottom of the water collection tank 9 is cone-shaped, which facilitates the convergence of condensate towards the outlet 10 for drainage. The bottom of the water collection tank 9 has an outlet 10 with a limiting groove 11. A fixing ring 12 is fixedly connected to the limiting groove 11. One end of the fixing ring 12 is fixedly connected to one end of a spring 13, and the other end of the spring 13 is fixedly connected to a buoyancy ball 14. The elastic force of the spring 13 is less than the buoyancy of the buoyancy ball 14. The buoyancy ball 14 fits against the upper end of the outlet 10. When there is a certain amount of condensate in the water collection tank 9, the buoyancy ball 14 can overcome the elastic force of the spring 13 and rise under the action of buoyancy, opening the outlet 10 for drainage.

[0021] The water-absorbing assembly includes a water-absorbing layer 4 made of a high-polymer water-absorbing material. A fixing net 5 is fixedly connected to the water-absorbing layer 4, and a water-collecting ring 6 is fixedly fitted around the outer ring of the fixing net 5. The size of the water-collecting ring 6 is the same as the size of the inner wall of the lower end of the U-shaped pipe section 3. This design ensures that the water-collecting ring 6 fits better against the bottom inner wall of the U-shaped pipe section 3, comprehensively collecting condensed water vapor. The water-collecting ring 6 has a water-collecting ring groove 18 with a U-shaped cross-section to facilitate the collection of condensed water. The water-collecting ring 6 is rotatably connected to the bottom inner wall of the U-shaped pipe section 3 via a rotating column 7. This configuration allows the water-absorbing layer 4 to be adjusted according to the working state. When the air compressor 1 is working, the water-absorbing layer 4 is rotated so that it is perpendicular to the cross-section of the U-shaped pipe section 3; when the air compressor 1 is not working, the water-absorbing layer 4 is rotated so that it is parallel to the cross-section of the U-shaped pipe section 3. A water-collecting pipe 8 is connected to the bottom of the water-collecting ring 6. The water-collecting pipe 8 passes through the bottom rotating column 7, is fixedly connected to it, and extends out of the bottom of the U-shaped pipe section 3.

[0022] The adjustment assembly includes a first bevel gear 15, a second bevel gear 16, and a motor 17. The first bevel gear 15 is sleeved on the outside of the water collection pipe 8 and located between the U-shaped pipe section 3 and the water collection tank 9. The output end of the motor 17 is fixedly connected to the second bevel gear 16, and the first bevel gear 15 meshes with the second bevel gear 16. The motor 17 drives the second bevel gear 16 to rotate, which in turn drives the first bevel gear 15 to rotate, ultimately realizing the rotation adjustment of the water collection pipe 8, and thus adjusting the rotation of the water absorption layer 4.

[0023] Example 2

[0024] As a further improvement to the above embodiments, the following technical solutions are provided: Figure 4 As shown, in order to further improve the water absorption effect, the difference from the above embodiment is that the water absorption layer 4 is set as two layers, which are respectively fixed on the two surfaces of the fixing net 5.
