Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a mechanical zero-gas-consumption drainage device. Background Art

[0002] The drainage device of the air compressor system is an important component to ensure the efficient operation of the compressed air system. Since condensed water is generated during the air compression process, if this water is not discharged in time, it will lead to a decline in the quality of the compressed air and even damage the air-using equipment. Therefore, the design and function of the drainage device are crucial. The drainage device of the air compressor system can achieve automatic drainage function through ingenious mechanical structure design, effectively improving the operating efficiency and safety of the compressed air system. It is an indispensable part of modern industrial production.

[0003] Existing drainage devices are widely used. However, due to design reasons, the existing drainage devices will discharge all the condensed water at one time. During the drainage process, some compressed air will be brought out, resulting in a large gas loss. In addition, the existing drainage devices can only drain water passively. When the air compressor system needs to be inspected and repaired, the sealing state of the drainage device cannot be fixed. Therefore, a mechanical zero-gas consumption drainage device is proposed to address the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a mechanical zero-gas consumption drainage device to solve the problem in the background art that the existing device will bring out some air when draining water and the existing drainage device cannot fix the sealing state.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A mechanical zero-gas consumption drainage device includes a drainage tank, a drainage groove is provided inside the drainage tank and runs through the drainage tank from top to bottom, a sealing ring is provided at the top of the drainage groove and is fixedly connected to the bottom end of the inner side of the drainage tank, a sealing ball is provided inside the sealing ring, the top of the sealing ball is fixedly connected to a floating block located inside the drainage tank, a clamping assembly is installed on the top of the floating block, and a water collecting pipe is provided vertically below the drainage groove and fixedly connected to the bottom end of the drainage tank.

[0007] Preferably, the clamping assembly includes a limit rod vertically arranged and fixedly connected to the top of the floating block, a limit spring is provided on the outside of the limit rod, a connecting plate is fixedly connected to the top of the limit spring, a connecting rod is fixedly connected to the outside of the connecting plate, and a baffle is fixedly connected to the top of the limit rod.

[0008] Preferably, the inner side of the sealing ring fits tightly with the outer side of the sealing ball, the outer diameter of the float is smaller than the inner diameter of the drainage tank, the limit rod passes through the connecting plate and is slidably connected to the connecting plate, the bottom end of the limit spring is fixedly connected to the top end of the float, and the end of the connecting rod away from the connecting plate is fixedly connected to the inner side of the drainage tank. There are multiple connecting rods, and the connecting rods are distributed in a polar axis pattern on the inner side of the drainage tank.

[0009] Preferably, the inner side of the sealing ball is rotatably connected to a universal ball, the bottom end of the universal ball is fixedly connected to a vertically arranged screw, the outer side of the screw is spirally connected to a threaded barrel, and the outer side of the threaded barrel is fixedly connected to a connecting block.

[0010] Preferably, the screw passes through the sealing ball and is rotatably connected to the sealing ball, the side of the connecting block away from the threaded barrel is slidingly connected to the inner side of the water collecting pipe, there are multiple connecting blocks, and the connecting blocks are polarly distributed on the inner side of the water collecting pipe.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the utility model, by providing a drainage trough, a sealing ring, a sealing ball, a floating block, a pressing assembly, a limiting rod, a limiting spring, a connecting plate, a connecting rod, a baffle and a water collecting pipe, when the condensate level is higher than the floating block, the floating block rises due to the buoyancy, the limiting spring is compressed, and the sealing ball at the bottom of the floating block separates from the sealing ring. At this time, the condensate is discharged through the drainage trough. When part of the condensate is discharged, the floating block drops, and the limiting spring is reset to drive the sealing ball to fit tightly with the inner side of the sealing ring, thereby completing the discharge of the condensate. This design can retain a part of the condensate inside the drainage tank, thereby preventing the air in the air compression system from being discharged through the drainage trough, reducing gas loss.

[0013] 2. In the utility model, by providing a universal ball, screw, threaded barrel and connecting block, when the drain tank needs to be sealed, the screw is turned. At this time, the screw and the universal ball rotate inside the sealing ball. Since the threaded barrel on one side of the connecting block limits the screw, the connecting block slides on the inside of the water collecting pipe and drives the threaded barrel to rise. When the connecting block fits tightly with the bottom end of the drain tank, the sealing ball is fixed on the inside of the sealing ring, and the condensed water cannot be discharged through the drain tank, thereby completing the sealing of the drain tank.

[0024] A mechanical zero-gas consumption drainage device includes a drainage tank 1, a drainage groove 2 is provided inside the drainage tank 1 and runs through the drainage tank 1 from top to bottom, a sealing ring 3 is provided on the top of the drainage groove 2 and is fixedly connected to the bottom end of the inner side of the drainage tank 1, a sealing ball 4 is provided on the inside of the sealing ring 3, and a floating block 5 located on the inner side of the drainage tank 1 is fixedly connected to the top of the sealing ball 4. A clamping assembly 6 is installed on the top of the floating block 5, and a water collecting pipe 7 is provided vertically below the drainage groove 2 and fixedly connected to the bottom end of the drainage tank 1. The floating block 5 can drive the sealing ball 4 to move when the condensed water level rises.

[0025] The clamping assembly 6 includes a limit rod 61 that is vertically arranged and fixedly connected to the top of the float 5. A limit spring 62 is provided on the outside of the limit rod 61. The top of the limit spring 62 is fixedly connected to a connecting plate 63. The outside of the connecting plate 63 is fixedly connected to a connecting rod 64. The top of the limit rod 61 is fixedly connected to a baffle 65. The design of the clamping assembly 6 can cooperate with the movement of the float 5 to compress the sealing ball 4. The inner side of the sealing ring 3 fits tightly with the outer side of the sealing ball 4. The outer diameter of the float 5 is smaller than the inner diameter of the drainage tank 1. The limit rod 61 passes through the connecting plate 63 and is slidably connected to the connecting plate 63. The bottom end of the limit spring 62 is fixedly connected to the top of the float 5. The end of the connecting rod 64 away from the connecting plate 63 is fixedly connected to the inside of the drainage tank 1. The number of the connecting rods 64 is multiple, and the connecting rods 64 are polar-axis-divided on the inside of the drainage tank 1. The cloth, the setting of multiple connecting rods 64 can fix the connecting plate 63 without affecting the flow of condensed water. The inner side of the sealing ball 4 is rotatably connected to the universal ball 8, and the bottom end of the universal ball 8 is fixedly connected to a vertically set screw 9. The outer side of the screw 9 is spirally connected to the threaded barrel 10, and the outer side of the threaded barrel 10 is fixedly connected to the connecting block 11. The setting of the universal ball 8 and the screw 9 can fix the sealing ball 4, so that the device is in a fixed sealing state. The screw 9 penetrates the sealing ball 4 and is rotatably connected to the sealing ball 4. The side of the connecting block 11 away from the threaded barrel 10 is slidably connected to the inner side of the water collecting pipe 7. There are multiple connecting blocks 11, and the connecting blocks 11 are polarly distributed on the inner side of the water collecting pipe 7. The setting of the connecting block 11 can fix the threaded barrel 10 and can drive the threaded barrel 10 to slide up and down.

[0026] Working process: When using the device, install the drain tank 1 at the drain outlet of the air compressor system. When condensed water is generated, the condensed water accumulates at the bottom end of the inner side of the drain tank 1. When the condensed water level is higher than the float 5, the float 5 rises due to buoyancy, and the limit rod 61 at the bottom end of the baffle 65 follows the float 5 to rise and slides inside the connecting plate 63 on the side of the connecting rod 64. The limit spring 62 is compressed, and the sealing ball 4 at the bottom end of the float 5 breaks away from the sealing ring 3. The connecting block 11 slides inside the water collecting pipe 7. At this time, the condensed water inside the drain tank 1 enters the inner side of the water collecting pipe 7 through the drain groove 2 and is discharged through the water collecting pipe 7. When a part of the condensed water inside the drain tank 1 is discharged, the float 5 drops, and the limit spring 62 resets to drive the limit rod 61 at the bottom end of the baffle 65 to slide inside the connecting plate 63 on the side of the connecting rod 64 until the sealing ball 4 is located at the sealing ring 3 The inner side is tightly fitted with the inner side of the sealing ring 3 to complete the discharge of condensed water. This design can retain a part of the condensed water inside the drain tank 1, thereby preventing the air in the air compression system from being discharged through the drain groove 2, reducing gas loss. The design of the clamping assembly 6 can cooperate with the movement of the floating block 5 to compress the sealing ball 4, thereby completing the sealing of the drain tank 1. When the drain tank 1 needs to be sealed, turn the screw 9. At this time, the screw 9 and the universal ball 8 rotate inside the sealing ball 4. Due to the limitation of the screw 9 by the threaded barrel 10 on one side of the connecting block 11, the connecting block 11 slides vertically on the inside of the water collecting pipe 7 and drives the threaded barrel 10 to rise. When the connecting block 11 is tightly fitted with the bottom end of the drain tank 1, the sealing ball 4 is fixed on the inside of the sealing ring 3, and the condensed water cannot be discharged through the drain tank 1, thereby completing the sealing of the drain tank 1.
