Description

Technical Field

[0001] This utility model belongs to the field of exhaust devices, and specifically relates to an automatic exhaust system for a water diaphragm pump. Background Technology

[0002] As a type of pump, the water diaphragm pump uses high-pressure water as a power source to drive the diaphragm, causing the diaphragm to change the pump's internal volume to achieve pumping. Combined with valve and pipeline design, it can achieve high-pressure pumping and is commonly used in long-distance, high-lift pipeline transportation of tailings slurry in mining enterprises. However, during operation, air inevitably mixes into the high-pressure water and tailings slurry. Because air is less dense than water and slurry, this air continuously escapes and accumulates at the highest points of the high-pressure water and tailings slurry within the pump. If the accumulated gas is not released in time, the sudden pressure changes in the high-pressure water and slurry caused by gas compression or release can easily generate a water hammer effect, causing the diaphragms to collide with each other and with the tank, resulting in severe vibration and noise that affects the normal operation of the equipment. In the use of existing technology, the common approach is to install manual or electrically controlled exhaust valves at the top of the tank or end cap for venting. Manual exhaust valves require personnel to manually open and close them at regular intervals, which is labor-intensive and dangerous. While remote electrically controlled exhaust valves can achieve a certain degree of venting control, they are prone to malfunctions or loss of control due to environmental factors and chip circuits, making it impossible to guarantee normal control. They also require personnel to monitor the operating status in real time for timely handling, which is inconvenient. Utility Model Content

Manual venting valves require manual opening and closing at regular intervals, which is labor-intensive and dangerous. While remotely controlled electrically controlled venting valves can achieve some venting control, they are prone to malfunctions or loss of control due to environmental factors and chip circuitry, making it difficult to guarantee normal operation. They also require real-time monitoring of the operating status for timely intervention, which is inconvenient.

[0008] Furthermore, the positioning control component is an electric push rod or an adjusting screw.

[0009] Furthermore, both the first piston and the second piston are interference-fitted with the gas collecting groove.

[0010] Furthermore, the exhaust device also includes a guide body, which is a hemisphere. The plane of the guide body is fixed to the cover plate, and the guide body is used to guide the air inlet when the cover plate seals it.

[0011] Furthermore, the maximum diameter of the guide body is smaller than the diameter of the air inlet.

[0012] Furthermore, the elasticity of the second elastic element is greater than that of the third elastic element.

[0013] Furthermore, the first elastic element, the second elastic element, and the third elastic element are all compression springs.

[0018] (III) Beneficial Effects

[0019] One of the above technical solutions has the following advantages or beneficial effects:

[0020] The system features an automatic exhaust device with a positioning control element and a second piston that can control the single exhaust volume. During air intake, the third elastic element and the linkage between the top ring and connecting ring automatically block the exhaust. Exhaust only begins automatically when the intake is blocked, ensuring automatic single-quantity exhaust. The system allows for adjustable single-exhaust volume settings, eliminating the need for electrical control and preventing system crashes. This ensures normal operation and ease of use. For easier adjustment in different situations, an electric push rod can be used as a positioning control element for remote single-quantity exhaust adjustment. This avoids long-term operation and reduces the risk of system crashes. Even in the event of a crash, exhaust can still occur, although the exhaust effect may not be optimal. This provides a buffer time for maintenance and reduces losses caused by malfunctions. Attached Figure Description

[0030] The exhaust device 5 includes an outer body 501, a first piston 502, a first elastic element 503, a second piston 504, a positioning control element 505, an air collection groove 506, an assembly plate 507, a second elastic element 508, an inner body 509, a cover plate 510, an air inlet 511, an exhaust connector 513, an exhaust main groove 514, an exhaust hole 515, a cover groove 516, a combined body 517, a top ring 518, a lifting groove 519, a connecting ring 520, a third elastic element 521, and a baffle 522. The outer body 501 has an air collection groove 506 inside. One end of the outer body 501 is covered and locked to the inner body 509. The combined body 517 is assembled on the outer body. An exhaust port 515 is provided between the inner body 501 and the inner body 509, and between the combined body 517 and the outer body 501. An air inlet 511 is provided on the side of the inner body 509 away from the outer body 501. The air inlet 511 communicates with the highest point of the exhaust point of the diaphragm pump 4. The air inlet 511 passes through the inner body 509 and communicates with the air collection groove 506. An assembly plate 507 is fixed in the air collection groove 506. A cover plate 510 is connected to the side of the assembly plate 507 adjacent to the air inlet 511 through a second elastic element 508. The cover plate 510 is used to cover the communication between the air inlet 511 and the air collection groove 506. The first piston 502 and the second piston 504 are both assembled in the air collection groove. Within 506, the first piston 502 and the second piston 504 are connected by a first elastic member 503. The second piston 504 is located on the side of the first piston 502 away from the mounting plate 507. The side of the second piston 504 away from the first piston 502 is fixedly connected to a positioning control member 505. The positioning control member 505 is used for displacement control of the second piston 504 within the air collection groove 506. The positioning control member 505 is fixedly connected to the outer body 501. An exhaust manifold 514 is formed between the interior of the outer body 501 and the inner body 509. The exhaust manifold 514 communicates with the air collection groove 506 through an exhaust hole 515. The side end face of the outer body 501... An exhaust connector 513 is provided, which communicates with the exhaust main groove 514. A lifting groove 519 is provided between the combined body 517 and the inner body 509. A connecting ring 520 is located in the lifting groove 519 and a third elastic element 521 is provided between it and the inner body 509. The inner ring end of the connecting ring 520 is fixedly connected to one end of the top ring 518.

The outer ring end of the connecting ring 520 is fixedly connected to one end of the baffle 522. The other end of the baffle 522 is located in the sealing groove 516. The sealing groove 516 covers the outside of the exhaust hole 515.

[0031] The positioning control component 505 is an adjusting screw.

[0032] The first piston 502 and the second piston 504 are both interference-fitted with the gas collecting groove 506.

[0033] The elasticity of the second elastic member 508 is greater than that of the third elastic member 521.

[0034] Among them, the first elastic element 503, the second elastic element 508 and the third elastic element 521 are all compression springs.

[0035] The maximum distance between the top of the baffle 522 and the top of the exhaust hole 515 is less than the maximum distance between the top of the connecting ring 520 and the top of the lifting groove 519.

[0036] The diaphragm pump 4 includes a water ring 401, a pump body 402, a diaphragm 403, a diaphragm venting ring 404, and a suction / discharge connector 405. The diaphragm 403 is installed inside the pump body 402. The water ring 401 is covered and fixed on the side end of the pump body 402 and is connected to the water source 1. The diaphragm 403 communicates with the water ring 401 in the slot of the pump body 402. The diaphragm venting ring 404 is connected to the highest point of the slot of the pump body 402. The diaphragm venting ring 404 is fixed to the top of the pump body 402. A venting device 5 is fixed to the top of the pump body 402 and the diaphragm venting ring 404. The highest point inside the pump body 402 and the diaphragm venting ring 404 are respectively connected to the air inlet 511 of the venting device 5. The suction / discharge connector 405 is provided at the bottom of the pump body 402.

[0037] The automatic venting system of the water diaphragm pump also includes a connecting pipe 2, a water pump 3, a pumping pipe 6, and a valve 7. The water source 1 is a circulating water tank. The water source 1 is connected to the water ring 401 through the connecting pipe 2 and the water pump 3. The pumping pipe 6 is connected to the inside of the pump body 402 through the pumping connector 405. Valves 7 are installed at both ends of the connection between the pumping pipe 6 and the pumping connector 405.

[0038] Among them, valve 7 is an electrically controlled valve.

[0039] In use, when the gas accumulated between the diaphragm 403 and the pump body 402 or inside the pump body 402 reaches a certain amount, as the water pump 3 draws water from the water source 1 into the space between the diaphragm 403 and the pump body 402, the expansion of the diaphragm 403 within the pump body 402 compresses the material and air already drawn into the pump body 402. At this time, the discharge pipe 6 opens the fixed valve 7 to discharge the material, while the air is pushed up by the pressure against the cover plate 510 and rises. During the initial rise of the cover plate 510, both the top ring 518 and the baffle 522 rise because the connecting ring 520 is pushed up by the third elastic element 521, until... When the connecting ring 520 rises to the highest point of the lifting groove 519, the baffle 522 will completely cover the exhaust hole 515 because the maximum distance between the top of the baffle 522 and the top of the exhaust hole 515 is less than the maximum distance between the top of the connecting ring 520 and the top of the lifting groove 519. As the air continues to press up, it will continue to rise. At this time, the air begins to enter the air collection groove 506. As the air continues to enter, the first piston 502 will be continuously compressed to the side of the second piston 504 until the pressure is insufficient or reaches the maximum limit. At this time, the air will be compressed and will increase in pressure as it continues to be compressed until it is difficult to enter.

[0040] When the water pump 3 draws water from between the diaphragm 403 and the pump body 402, the pressure inside the pump body 402 decreases. At this time, the cover plate 510 is pressed by the second elastic element 508 to seal the connection between the air inlet 511 and the air collection groove 506. As the cover plate 510 is sealed, the top ring 518 is pressed and drives the connecting ring 520 to descend and reset, causing the baffle 522 to open the exhaust port 515. At this time, the air in the air collection groove 506 will be continuously discharged from the exhaust joint 513 due to the high pressure and the thrust of the first elastic element 503 pressing the first piston 502 to reset, realizing a quantitative air intake and exhaust cycle. As the pump body 402 runs, exhaust is repeated in this way, eliminating the need for manual control and remote electric control, realizing mechanical automatic quantitative cycle exhaust, avoiding situations such as machine failure, and ensuring normal operation of exhaust.

[0041] Finally, the positioning control component 505 can also control the limit of the first piston 502 in the air collection groove 506, so that the single exhaust volume of the air collection groove 506 can be set according to the requirements. This can prevent the material conveyed by the pump body 402 from being compressed into the air collection groove 506 due to an excessively large air collection groove 506, and can also prevent the single cycle exhaust from being insufficient due to an excessively small air collection groove 506, which is convenient to use.

[0042] Example 2:

[0043] As another preferred embodiment, the positioning control component 505 is an electric push rod, which enables the exhaust device 5 to remotely adjust and control the single-time quantitative exhaust. The control of the positioning control component 505 does not need to run for a long time, which can reduce the occurrence of system crashes. Even if the system crashes, the exhaust device 5 can still exhaust normally, but the exhaust effect cannot reach the optimal state. This allows for more buffer time for maintenance and reduces the losses caused by the failure. The remaining structure and effects are the same as in Embodiment 1.

[0044] Example 3:

[0045] As another preferred embodiment, the exhaust device 5 further includes a guide body 512, which is a hemisphere. The plane of the guide body 512 is fixed on the cover plate 510. The guide body 512 is used to guide the cover plate 510 when sealing the air inlet 511. The maximum diameter of the guide body 512 is smaller than the diameter of the air inlet 511, ensuring that the cover plate 510 is accurately positioned each time it is sealed. The remaining structure and effects are the same as those in the aforementioned embodiments.
