Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a manual-automatic integrated automatic drainer. Background Art

[0002] During the use of pneumatic equipment, as time accumulates, trace amounts of moisture and impurities in the compressed air will form liquid accumulation in the air delivery pipe. These accumulated liquids may contain corrosive components such as acids, alkalis, and salts. When the accumulated liquid enters the pneumatic equipment with the gas, there is a situation where the internal parts of the pneumatic equipment are corroded by the accumulated liquid. Therefore, a drainage device is required to remove trace moisture and impurities in the compressed air to ensure the normal operation and service life of the pneumatic device.

[0003] The automatic drainer includes a water cup, a float, a piston and an internal drainage channel. The up and down floating of the float reflects the changes in the liquid level in the water cup. When the float floats up and down, the piston follows the movement, thereby opening and closing the drainage channel to achieve the purpose of automatic drainage.

[0004] When the automatic drainage is not smooth due to the failure of the float, the automatic drainer fails and needs to be manually removed to drain the water. In addition, there are also cases where the liquid level in the water cup is low and the float does not float up, and drainage operations are also required. However, the automatic drainer is limited by the action of the float to drain water and cannot automatically drain water in the above situation.

[0005] In the related art, since the automatic drainer has many accessories and a complex structure, it also has the defects of high production cost and high difficulty in product maintenance. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The embodiment of the utility model provides a manual and automatic integrated automatic drainer, such as Figures 1 to 7As shown, the automatic drainer includes a tubular water cup 1, which has a cavity. One end of the tubular water cup 1 is a water inlet 2, and the other end of the tubular water cup 1 is a water outlet 3. A limit seat 4 is installed at the water outlet 3. A piston 5 is installed at the end of the limit seat 4 close to the water inlet 2. A float 6 is provided on the sliding sleeve at the end of the limit seat 4 close to the water inlet 2. A swing rod 7 is connected between the piston 5 and the float 6. The float 6 drives the piston 5 to move in the same direction through the swing rod 7. The end of the limit seat 4 away from the water outlet 3 is detachably connected with a manual-automatic switching member 8, and the manual-automatic switching member 8 is arranged toward the piston 5. A first drainage channel 9 communicating with the cavity is opened in the limit seat 4, the piston 5 is located in the first drainage channel 9, and the manual-automatic switching member 8 has a second drainage channel 24 communicating with the first drainage channel 9.

[0031] The float 6 has a drainage posture and a standby posture. When the float 6 switches from the standby posture to the drainage posture, the rocker arm 7 drives the piston 5 to deflect upward, and the first drainage channel 9 is connected to the second drainage channel 24; when the float 6 switches from the drainage posture to the standby posture, the rocker arm 7 drives the piston 5 to deflect downward and resist against the manual-automatic switching component 8 to close the first drainage channel 9, and the first drainage channel 9 is not connected to the second drainage channel 24.

[0032] Specifically, in this embodiment, the automatic drain has a preset drainage liquid level and is vertically installed in the external pipeline. When the liquid level in the tubular water cup 1 reaches the drainage liquid level, the float 6 floats toward the water inlet 2 under the action of buoyancy, and then drives the piston 5 to move upward through the rocker rod 7, so that the lower part of the piston 5 no longer contacts the manual-automatic switching part 8. At this time, the first drainage channel 9 is connected to the second drainage channel 24.

[0033] When the liquid level in the tubular water cup 1 does not reach the drainage level, the gravity of the float 6 is less than the buoyancy, and the piston 5 is against the manual-automatic switching member 8 under its own gravity and the limit of the swing rod 7. At this time, the first drainage channel 9 is not connected to the second drainage channel 24. Among them, a limit block 21 is protruded at one end of the float 6 away from the water inlet 2, and the limit block 21 is against the limit seat 4 to keep the float 6 in a standby position.

[0034] In a preferred embodiment of the utility model, the limit seat 4 includes a limit shell 41 screwed to the water outlet 3 and a connecting rod 42 fixed to the limit shell 41 on the side facing the water inlet 2, the float 6 is slidably connected to the connecting rod 42, the limit shell 41 is provided with a mounting groove 91 for installing the piston 5, the groove of the mounting groove 91 is connected to the second drainage channel 24, the side wall of the limit shell 41 is provided with a through hole 92 connecting the mounting groove 91 and the cavity, and the mounting groove 91 and the through hole 92 form the first drainage channel 9.

[0035] Specifically, in this embodiment, the float 6 is provided with a clearance hole 22 along the axis, and the connecting rod 42 is inserted into the clearance hole 22 so that the float 6 can slide along the connecting rod 42 when floating up and down.

[0036] In a preferred embodiment of the utility model, a limiting convex ring 10 is provided in the middle of the limiting housing 41, and the inner diameter of the limiting convex ring 10 is smaller than the inner diameter of the mounting groove 91, so that the piston 5 is limited between the limiting convex ring 10 and the bottom of the mounting groove 91, and when the piston 5 and the limiting convex ring 10 are against each other, a gap is left between the piston 5 and the limiting convex ring 10.

[0037] Specifically, in this embodiment, when the piston 5 abuts against the limiting convex ring 10 , the manual-automatic switching member 8 abuts against the lower edge of the piston 5 to close the first drainage channel 9 .

[0038] In a preferred embodiment of the utility model, a limiting plate 11 is fixed on one side of the float 6 facing the limiting seat 4, the limiting plate 11 has a limiting hole 12, one end of the rocker arm 7 is passed through the limiting hole 12, the other end of the rocker arm 7 is passed through the piston 5, the outer diameter of the rocker arm 7 is smaller than the inner diameter of the limiting hole 12, and a limiting portion 13 is die-casted at one end of the rocker arm 7 close to the limiting plate 11, and the outer diameter of the limiting portion 13 is larger than the inner diameter of the limiting hole 12.

[0039] Specifically, in this embodiment, when the float 6 slides up and down along the connecting rod 42, the end of the rocker arm 7 inserted in the limit plate 11 swings accordingly, thereby driving the other end of the rocker arm 7 to move up or down. The swinging action of the rocker arm 7 drives the piston 5 to deflect up and down, thereby controlling the opening and closing of the first drainage channel 9.

[0040] In a preferred embodiment of the present invention, a first sealing ring 14 is disposed on the side of the limiting convex ring 10 of the limiting housing 41 close to the manual-automatic switching member 8 .

[0041] Specifically, in this embodiment, the limiting shell 41 is inserted into the water outlet 3, and the first sealing ring 14 is located on the inner side of the water outlet 3 to prevent the accumulated liquid in the cavity from leaking from the connection between the limiting shell 41 and the water outlet 3.

[0042] One end of the limiting shell 41 away from the float 6 over-extends beyond the water outlet 3 , and a gasket is provided at the end of the limiting shell 41 away from the float 6 to prevent the limiting shell 41 from being loosened from the tubular water cup 1 .

[0043] In a preferred embodiment of the present invention, the automatic drainer further comprises a filter 15 , and a support 16 is fixed to one side of the tubular water cup 1 close to the water inlet 2 , and the filter 15 is detachably connected to the support 16 .

[0044] In a preferred embodiment of the present utility model, the filter element 15 includes a mounting frame 151 and a filter screen 152 fixed to the mounting frame 151. The mounting frame 151 is clamped on the side of the support 16 away from the water outlet 3. A positioning groove 17 is provided on the side of the support 16 away from the water outlet 3. The mounting frame 151 is protrudingly provided with a positioning block 18 clamped in the positioning groove 17.

[0045] Specifically, in this embodiment, by providing the filter element 15 , it is possible to prevent the particles in the accumulated liquid from clogging the first drainage channel 9 and the second drainage channel 24 .

[0046] When the mounting frame 151 is placed on the support platform 16 , the positioning block 18 is engaged in the positioning groove 17 to prevent the filter element 15 from moving and loosening due to vibration of the equipment in an actual application environment.

[0047] In a preferred embodiment of the present invention, a pull ring 19 is provided on a side of the mounting frame 151 away from the water outlet 3 .

[0048] Specifically, in this embodiment, the pull ring 19 is rotatably connected to the side of the mounting frame 151 away from the water outlet 3. When the user needs to clean the filter screen 152, the automatic drain is removed from the external pipeline, and then the filter element 15 can be removed by rotating and pulling the pull ring 19. The operation is simple and convenient, which improves the maintenance efficiency of the automatic drain.

[0049] In a preferred embodiment of the present utility model, the manual-automatic switching member 8 includes a plunger portion 81 and a hand-tightening portion 82 fixed to one end of the plunger portion 81, the plunger portion 81 is screwed to the limit shell, the end of the plunger portion 81 away from the hand-tightening portion 82 has a ejector portion 20, and the second drainage channel 24 passes through the ejector portion 20, the plunger portion 81 and the hand-tightening portion 82 in sequence; when the float 6 is in the standby posture, the piston 5 and the end of the ejector portion 20 away from the plunger portion 81 are abutted to close the second drainage channel 24.

[0050] Specifically, in the present embodiment, the second drainage channel 24 is in the shape of a pinhole in the ejector pin 20 and is opened at the top end of the ejector pin 20. When the piston 5 abuts against the limiting convex ring 10, the top end of the ejector pin 20 abuts against the bottom edge of the piston 5, thereby isolating the first drainage channel 9 from the second drainage channel 24.

[0051] The limiting shell is provided with an insertion hole 93 for the plunger 81 to be inserted and screwed, and the first drainage channel 9 includes a mounting groove 91 for the piston 5 to be installed, a through hole 92 respectively connected to the cavity and the mounting groove 91, and a insertion hole 93 connected to the mounting groove 91. When the plunger 81 is inserted and screwed into the insertion hole 93, the notch of the mounting groove 91 is connected to the second drainage channel 24.

[0052] A second sealing ring 23 is sleeved on the plunger portion 81 to prevent the accumulated liquid from leaking from the connection between the plunger portion 81 and the limiting housing 41 .

[0053] In summary, the manual-automatic integrated automatic drainer provides an automatic drainage mode and a manual drainage mode. In the automatic drainage mode, when the liquid level in the tubular water cup 1 reaches a preset value, the float 6 floats up, and the end of the rocker arm 7 connected to the float 6 is lifted, so that the piston 5 moves up. At this time, the second drainage channel 24 is connected to the first drainage channel 9, and the accumulated liquid in the tubular water cup 1 is discharged along the first drainage channel 9 and the second drainage channel 24; when the user needs to perform drainage operations when the liquid level in the tubular water cup 1 is lower than the preset value or the float 6 does not move smoothly, the user can turn the manual-automatic switching part 8 to move the ejector pin 20 away from the piston 5. At this time, the first drainage channel 9 is connected to the second drainage channel 24, and drainage operations can be performed. The operation is simple and convenient.

[0054] In addition, since the product has a simple structure, the piston 5 and the ejector needle part 20 are easy to match, there is no need for high-precision processing of parts, and the requirements for the process level are relatively low, which effectively reduces the production cost of the automatic drain; when the user needs to maintain the automatic drain, remove the tubular water cup 1, and then remove the manual-automatic switching part 8, the filter part 15, the float 6 and the limit seat 4 in turn. The connection logic between the various parts is simple and easy to understand, making the disassembly and assembly method simple and easy to operate, thereby improving maintenance efficiency.
