Description

Technical Field

[0001] This invention relates to the field of dust collector technology, and in particular to a three-way dust collector with automatic drainage function. Background Technology

[0002] Currently, various types of air pressure pipelines are widely used in both daily life and industry. However, during application, especially after the air pressure enters certain equipment, the air in the pipeline may be unclean. During the high-pressure air production process by the compressor, a large amount of moisture may condense, resulting in a significant amount of dust and moisture in the equipment. If this dust and moisture are not treated promptly, they will enter the air-using equipment through the air pressure pipeline. Dust will affect the normal operation of the equipment, while the long-term accumulation of moisture can easily cause corrosion, reducing the service life of the equipment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a three-way dust collector with automatic drainage function, which can automatically drain water even without wind pressure. This is safe, reliable, and efficient, reducing moisture, dust particles, and impurities in existing wind pressure pipes, improving the quality of use of the dust collector, and extending the service life of the equipment.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] The valve body has a cavity channel located between two main pipe diameter interfaces. The top of the valve body has an upper passage connecting to the equipment pipe diameter interface. A dust filter device is installed in the upper passage. A lower plug is installed at the bottom of the valve body. A concave structure is provided in the middle of the valve body. A gap is formed between the baffle at the bottom of the cavity channel and the concave structure to filter impurities and moisture into the lower part of the valve body by centrifugation under wind pressure.

[0007] The valve body is equipped with a check plug at the bottom. The buoyancy drainage mechanism passes through the check plug and is equipped with a slide valve stop. A first spring is provided between the top of the slide valve stop and the check plug, and a second spring is provided between the bottom of the slide valve stop and the lower plug. The buoyancy drainage mechanism is connected to the drain hole of the lower plug. The slide valve stop moves downward under the action of the gravity of the water in the buoyancy drainage mechanism so that the water in the valve body is discharged through the gap formed between the buoyancy drainage mechanism and the check plug.

[0008] As a further implementation, the upper passage of the valve body is connected to the main pipe interface through the gap between the cavity channel and the inner side of the valve body, and the dust filter device is provided with several layers of protective mesh.

[0009] As a further implementation, the dust filter is covered with a dust cap, which is sealed to the top surface of the valve body, and the inside of the dust cap has a space for connecting the pipe diameter interface of the equipment.

[0010] As a further implementation, the cavity channel is a hollow columnar structure, with its two ends not in contact with the main pipe diameter interface, the concave structure having an opening in the middle, and the baffle located at the opening of the concave structure.

[0011] As a further implementation, the bottom of the valve body is provided with a lower valve body mounting interface for installing a lower plug. The top of the lower valve body mounting interface is provided with a retainer for abutting the top of the check plug. The center of the top of the lower plug is provided with a groove, and the center of the groove is provided with a drain hole for the lower plug.

[0012] As a further implementation, the check plug has a bowl-shaped structure with a circular opening at its center, and the first spring is sleeved around the periphery of the circular opening.

[0013] As a further implementation, the buoyancy drainage mechanism includes a slide valve, which is disposed through a circular opening and the outer diameter of the slide valve is smaller than the inner diameter of the circular opening. The bottom of the slide valve is a slide valve base, and the inside is a hollow slide valve structure. An air hole is provided below the hollow slide valve structure, and the upper part is connected to the outside through the slide valve mesh structure. The slide valve is blocked on the periphery of the slide valve and located below the check plug.

[0014] As a further implementation, the buoyancy drainage mechanism also includes an upper float and a float support. The top of the upper float has an umbrella-shaped structure, the bottom has a hollow structure and a drainage hole at the bottom end. The upper float is sleeved on the slide valve. The float support is sleeved around the upper float so that when the upper float is raised, the drainage hole connects with the mesh structure of the slide valve.

[0015] As a further implementation, one end of the second spring abuts against the bottom surface of the slide valve stop, and the other end abuts against the groove of the lower plug; one end of the first spring abuts against the top surface of the slide valve stop, and the other end abuts against the bottom of the check plug near the edge.

[0016] As a further implementation, a water passage trough is provided around the buoy.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. This invention creates a gap between the baffle and the concave structure to filter impurities and moisture into the lower part of the valve through centrifugal force under wind pressure; by setting a buoyancy drainage mechanism, it can automatically drain water in the absence of wind pressure, which is safe, reliable and efficient, reducing the moisture, dust particles and impurities in the existing wind pressure pipeline, improving the quality of use of the dust collector and extending the service life of the equipment.

[0021] 4. The outer diameter of the slide valve of the present invention is smaller than the inner diameter of the circular opening of the check plug. When the water volume inside the hollow structure of the slide valve increases, the slide valve can disengage from the check plug through the action of the first spring, and water and impurities can be discharged through the gap.

[0022] 5. The top of the float rod of the present invention has an umbrella-shaped structure, which is lightweight and can ensure that when dust enters the lower part of the valve body again under wind pressure, the dust will not flow out due to wind pressure flow. Attached Figure Description

[0042] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0043] Example 1

[0044] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 1As shown in Figure 1, a three-way dust collector with automatic drainage function includes a valve body 7. The valve body 7 has three pipe diameter interfaces near the top, including two main pipe diameter interfaces 5 on the same straight line and one equipment pipe diameter interface 6 perpendicular to the main pipe diameter interface 5. The equipment pipe diameter interface 6 is used to connect to the air supply equipment.

[0045] As shown in Figures 2 and 6, the valve body 7 has a cavity channel 27 located between two main pipe diameter interfaces 5. The cavity channel 27 is a hollow columnar structure with its two ends open and not in contact with the main pipe diameter interfaces 5. The valve body has an upper passage 26 at the top center that connects to the equipment pipe diameter interface 6. A dust filter device 9 is installed at the upper passage of the valve body.

[0046] As shown in Figures 2 and 6, there is a gap between the cavity channel 27 and the top surface of the valve body 7. The air coming from the main pipe diameter interface 5 can enter the gap through the space between the cavity channel 27 and the main pipe diameter interface 5, and pass upward through the upper passage 26 of the valve body.

[0047] A valve body boss 25 is provided at the center of the top of the valve body 7, which is located at the top of the upper passage 26 of the valve body. The dust filter device 9 is snapped into the valve body boss 25 for positioning the dust filter device 9.

[0048] like Figure 4 As shown, the dust filter device 9 includes an inner protective net 24 and an outer protective net 23, which are used to filter impurities. The impurities carried by the wind pressure leading to this location are filtered by the dust filter device 9.

[0049] like Figure 1 Figures 2(a) and 2(b) and Figure 3 As shown, the dust filter device 9 is covered with a dust cap 1, which is fixedly connected to the top surface of the valve body 7. Its height is adapted to the dust filter device 9 to press down the dust filter device 9 and prevent it from moving due to wind pressure.

[0050] like Figure 3 As shown, the dust cap 1 includes a dust cap top 22, a dust cap buckle 19 at its bottom edge, a dust cap pad 21 on its bottom surface, and dust cap bolt holes 20 on the dust cap 1. The dust cap 1 is fixedly connected to the top of the valve body by bolts 2, washers 3, and nuts 4. A sealing gasket 10 is provided between the dust cap 1 and the valve body for sealing and preventing air leakage.

[0051] As shown in Figure 2(b), the dust cap 1 has a space inside that connects to the equipment pipe interface. The airflow passes through the upper passage 26 of the valve body, filters impurities, and then enters the equipment pipe interface 6.

[0052] As shown in Figure 2, a concave structure 28 is provided in the middle of the valve body 7. The concave structure 28 has an opening in the middle and is connected to the lower part of the valve body 7. The concave structure 28 is lower than the main pipe diameter structure. The pipe channel 27 is located above the concave structure 28. A baffle 29 is provided at the bottom of the pipe channel 27. The baffle 29 is located at the opening of the concave structure 28, and a gap is formed between the baffle 29 and the concave structure 28. When centrifugal force is generated during ventilation, impurities and moisture are filtered into the lower part of the valve. The air pressure flow direction is shown in Figure 2.

[0053] like Figure 1 As shown in Figures 2 and 6, the bottom of the valve body 7 is provided with a lower valve body mounting interface 31. The lower plug 18 is installed through the lower valve body mounting interface 31. The lower plug and the lower valve body mounting interface 31 are installed by bolts and sealing rings 16.

[0054] The lower plug 18 has a boss structure at its top, with a groove at its center extending downwards by a predetermined distance. A drain hole 43 is located at the bottom center to drain water from the valve body. The outer diameter of the boss structure matches the inner diameter of the mounting interface 31 at the bottom of the valve body. The step formed by the boss structure abuts against the lower end face of the valve body.

[0055] As shown in Figure 6, a check plug 14 is installed at the top of the lower mounting interface 31 of the valve body 7. The top of the lower mounting interface 31 of the valve body is provided with an annularly arranged retainer 30, which is used to abut the top of the check plug to prevent the check plug 14 from moving upward.

[0056] As shown in Figure 10, the bottom center of the check plug 14 has a circular opening that extends downwards by a set distance, forming a bowl-shaped structure. The top edge has a rounded sliding structure 42 so that all water entering the check plug 14 can be discharged downwards through the circular opening via the rounded sliding structure 42.

[0057] As shown in Figure 2, the buoyancy drainage mechanism in the lower part of the valve body 7 passes through the check plug 14 and is equipped with a slide valve stop 39. A first spring 15 is provided between the top of the slide valve stop and the check plug 14, and a second spring 17 is provided between the bottom of the slide valve stop and the lower plug 18. The buoyancy drainage mechanism is connected to the drain hole 43 of the lower plug. The slide valve stop 39 moves downward under the action of the gravity of the water in the buoyancy drainage mechanism so that the water in the valve body 7 is discharged through the gap formed between the buoyancy drainage mechanism and the check plug 14.

[0058] As shown in Figures 2 and 9, the buoyancy drainage mechanism includes an upper float 11, a float support 12, and a slide valve 13. The slide valve 13 has a columnar structure, with four slide valve bases 41 at its bottom, and gaps between the slide valve bases 41. As shown in Figure 9(b), the interior of the slide valve 13 is a hollow slide valve structure 38, and the top side is a slide valve mesh structure 37, which connects to the outside. An air hole 40 is provided below the hollow slide valve structure 38, allowing water entering the slide valve 13 to be discharged downwards through the air hole 40.

[0059] The slide valve base 41 is located around the air hole 40 and will not interfere with the drainage of water. The slide valve 13 has a slide valve retainer 39 on its lower periphery, and the slide valve retainer 39 has a ring structure.

[0060] like Figure 7 As shown, the top of the float rod 11 has an umbrella-shaped structure 32, and the bottom of the rod-shaped structure has a hollow bottom structure 33 with multiple drainage holes 34 on the circumferential side of the bottom end. The umbrella-shaped structure of the float rod 11 is lightweight, and the umbrella-shaped structure 32 can ensure that when dust enters the lower part of the valve body 7 again due to air pressure, the dust will not flow out due to air pressure flow.

[0061] like Figure 8 As shown, the cross-section of the float 12 is circular, with a central opening called the float center hole 35. The interior is hollow and closed. Multiple water passage grooves 36 are evenly arranged around the float 12 for water to pass through.

[0062] In this embodiment, the slide valve 13 is disposed through the circular opening of the check plug 14, and the outer diameter of the slide valve is smaller than the inner diameter of the circular opening.

[0063] As shown in Figure 2, the slide valve 13 passes through the circular opening of the check plug 14, the slide valve stop 29 is located below the check plug, the first spring 15 is sleeved on the periphery of the circular opening, and one end of the first spring 15 abuts against the top surface of the slide valve stop 39, and the other end abuts against the bottom of the check plug 14 near the edge.

[0064] The slide valve base 41 at the bottom of the slide valve 13 can move up and down in the groove of the lower plug 18. The second spring 17 is sleeved on the periphery of the slide valve, with one end abutting against the bottom surface of the slide valve stop and the other end abutting against the groove of the lower plug 18.

[0065] The upper float 11 is sleeved on the top of the slide valve through the hollow structure 33. The float 12 is sleeved on the periphery of the upper float 11 through the central hole 35 of the float so that when the upper float 11 is raised, the drain hole 34 is connected to the slide valve mesh structure 37, and water can enter the slide valve hollow structure 38 through the drain hole 34 and the slide valve mesh structure 37.

[0066] In its natural state, the elastic force of the second spring 17 is greater than that of the first spring 15, allowing the slide valve stop 39 to abut against the circular opening. The diameter of the slide valve stop 39 is greater than the diameter of the circular opening but smaller than the inner diameter of the mounting interface 31 at the bottom of the valve body. When the slide valve stop 39 abuts against the bottom of the check plug 14, the bottom of the check plug 14 is sealed, preventing water from draining from the circular opening and also preventing air pressure leakage.

[0067] In this embodiment, when a large amount of water is stored in the lower part of the dust collector, the water passes through the water tank 36 and is located in the lower part of the valve body. As the water volume increases, the float 12 floats under the buoyancy and pushes the upper float 11 up, disengaging it from the slide valve 13. When the height of the drain hole 34 is consistent with the slide valve mesh structure 37, the water enters the slide valve mesh structure 37 through the drain hole 34 and flows into the slide valve hollow structure 38. Finally, it slowly flows out from the air hole 40 through the lower drain hole 43.

[0068] During use, this automatic drainage tee dust collector relies primarily on buoyancy for drainage. Therefore, it is essential that the valve body 7 be perpendicular to the ground during installation. Its specific drainage working principle is as follows:

[0069] First, initially, in a windless state, the upper float 11 is subjected to gravity, the upper part of the hollow structure 33 contacts the top of the slide valve 13, and the slide valve stop 39 is subjected to the elastic force of the second spring 17, so that the slide valve stop 39 contacts the check plug 14, forming a sealed state.

[0070] Secondly, when the dust collector enters the working state, the lower part of the valve body 7 of the newly put-in dust collector has not yet accumulated moisture. After the main air pressure enters the dust collector, due to the air pressure pressing on the upper float 11 and the float support 12, plus the weight of the upper float 11, the upper float 11 continues to move downward. The upper part of the hollow structure 33 of the upper float 11 is still in contact with the end of the slide valve 13, so that the slide valve 13 is subjected to a downward force. The second spring 17 at the bottom of the slide valve 13 and the slide valve stop 39 cooperate to subject the slide valve 7 to an upward force. At this time, the check plug 14 also moves downward under the action of air pressure. Since the elastic force of the first spring 15 is less than the elastic force of the second spring 17, the check plug 14 contacts the slide valve stop 39 to form a seal.

[0071] Third, after a period of use, when a certain amount of moisture enters the valve body 7, during operation, due to the wind pressure inside the valve body 7, the float 12 and the upper float rod 11 inside the valve body 7 are continuously downward under the wind pressure, and the slide valve stop 39 is still in contact with the check plug 14, forming a seal.

[0072] Fourth, after a period of use, when a large amount of water enters the valve body and there is no working, i.e. no air pressure in the pipeline, the float 12 will move upward due to the buoyancy of the water. When the float contacts the upper float rod 11, it will drive the umbrella-shaped structure 32 of the upper float rod 11 to move upward together.

[0073] When the upper float 11 moves a certain distance, that is, the drain hole 34 at the lower part of the upper float 11 moves to the mesh structure 37 of the slide valve, forming a passage, water enters the hollow structure 38 of the slide valve, and water is stored in the hollow structure 38. The water is discharged through the air hole 40 and the lower plug drain hole 43, but the speed at which water in the valve body 7 enters the hollow structure 38 of the slide valve is greater than the drainage speed of the air hole 40. Although water flows out from the valve base 41, the flow rate is slow. At this time, the weight of the valve increases, and the check plug 14 is unable to descend due to the action of the first spring 15. The valve 13 descends. When the weight of the valve is greater than the elastic force of the second spring 17, the valve stop 39 disengages from the bottom surface of the check plug 14, leaving a gap between the top of the valve stop 39 and the bottom surface of the check plug 14. At this time, the water in the dust collector valve flows out through the gap between the circular opening and the side of the valve. The float 12 descends as the water accumulation in the valve body 7 decreases. After the water in the hollow structure 38 of the valve flows out, the weight of the valve 13 is reduced, and the upper float 11 falls. The drain hole 34 of the upper float 11 is misaligned with the mesh structure 37 of the valve, forming a closed passage. The first spring 17 lifts the valve 13 again, and the valve stop 39 contacts the check plug again, forming a seal. After the drainage is completed, the impurities located at the bottom of the valve body dissolve in the water and are discharged together.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
