Description

Technical Field

[0001] This utility model relates to the field of vacuum drainer technology, and in particular to an automatic vacuum drainer. Background Technology

[0002] Vacuum drainers are typically installed at the front end of a vacuum pump to prevent water from entering the pump with the airflow, thus avoiding performance degradation or damage. Existing drainers often experience problems such as the drain pipe becoming clogged with deposits, preventing drainage, or deposits accumulating on the inner wall of the drain pipe, reducing its diameter and slowing drainage, making manual cleaning extremely difficult.

[0003] Furthermore, existing vacuum drainers all rely on manual operation of valves to open or close the drain outlet. While this method achieves the drainage function, the manual operation results in high labor intensity for the operator.

[0004] Therefore, existing vacuum drainers suffer from technical problems such as easy clogging and inconvenient operation. Summary of the Invention

[0005] The present invention provides an automatic vacuum drainer, which solves the technical problems of easy clogging and inconvenient operation of existing vacuum drainers.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A vacuum automatic drainer includes a vacuum chamber, the vacuum chamber being provided with a drain assembly;

[0008] The vacuum chamber includes an inner cavity, and a partition is provided inside the inner cavity. The partition divides the inner cavity into a vacuum chamber and a water storage chamber. The partition is provided with a communication hole connecting the vacuum chamber and the water storage chamber. The vacuum chamber is also provided with a drain hole communicating with the water storage chamber.

[0009] The drainage assembly includes a slide rod slidably connected to the vacuum chamber. The slide rod is provided with an upper piston for opening or sealing the communication hole. The slide rod is also provided with a lower piston for opening or sealing the drainage hole. The drainage assembly also includes a drive mechanism for driving the slide rod to reciprocate.

[0010] In the non-drainage state, the drive mechanism drives the slide rod to move and causes the lower piston to seal the drain hole first, and then the upper piston opens the connecting hole. In the drainage state, the drive mechanism drives the slide rod to move and causes the upper piston to seal the connecting hole first, and then the lower piston opens the drain hole.

[0011] Preferably, the partition and the vacuum chamber are an integral structure, or the partition is welded to the vacuum chamber.

[0012] Preferably, the partition is provided with an upper cylinder that cooperates with the upper piston. The upper cylinder communicates with the connecting hole and is coaxially arranged with the connecting hole. The upper cylinder is welded to the partition, or the upper cylinder and the partition are an integral structure.

[0013] Preferably, the vacuum chamber is provided with a lower cylinder that cooperates with the lower piston. The lower cylinder and the vacuum chamber are an integral structure. The lower cylinder and the upper cylinder are coaxially arranged. The lower cylinder communicates with the drain hole.

[0014] Preferably, the partition is frustum-shaped and disposed inside the vacuum chamber, and the connecting hole is located at the lowest position of the partition.

[0015] Preferably, the driving mechanism includes a base, a lead screw rotatably connected to the base, a slide rod having a screw hole that mates with the lead screw, a guide post on the base, and a guide hole on the slide rod that mates with the guide post.

[0016] Preferably, the slide bar is provided with a guide plate, and the guide hole is provided in the guide plate.

[0017] Preferably, the guide plate is welded to the slide rod; or, the guide plate and the slide rod are an integral structure.

[0018] Preferably, the base is also provided with a motor that drives the lead screw to rotate. The motor is fixed to the base by screws, and the output shaft of the motor and the lead screw are an integral structure.

[0019] Preferably, the vacuum chamber is fixed to the base by a support column, and a drainage groove is provided between the motor and the vacuum chamber. The drainage groove is located directly below the drainage hole, and the water discharged from the drainage hole enters the drainage groove under the action of gravity.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] By setting up an upper piston and a lower piston, the upper piston can seal the connecting hole, and the lower piston can seal the drain hole. Both the upper and lower pistons are driven by a drive mechanism via a slide rod. When drainage is needed, the slide rod can be moved directly by the drive mechanism, thereby sealing the connecting hole and opening the drain hole. At this time, the drain hole can drain normally, making operation very convenient. At the same time, the piston needs to move inside the drain hole, which can remove the deposits on the side wall of the drain hole, making the drain hole less prone to clogging and the vacuum automatic drainer easy to maintain.

[0022] By setting up a vacuum chamber and a water storage chamber, which are connected by a connecting hole, the vacuum chamber and the water storage chamber are in normal operation, allowing water generated in the vacuum chamber to enter the water storage chamber through the connecting hole. When drainage is needed, simply moving the slide rod and using the upper piston to seal the connecting hole can isolate the vacuum chamber and the water storage chamber, eliminating the need to stop the machine during the water inlet and outlet processes.

[0023] By setting up a drive mechanism, the slide bar does not require direct manual operation, reducing the labor intensity of operators. Attached Figure Description

[0034] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0035] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0036] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0037] Reference Figures 1 to 6 As shown, a vacuum automatic drainer includes a vacuum chamber 1, wherein the vacuum chamber 1 is provided with a drain assembly;

[0038] The vacuum chamber 1 includes an inner cavity, and a partition 11 is provided in the inner cavity. The partition 11 divides the inner cavity into a vacuum chamber 12 and a water storage chamber 13. The partition 11 is provided with a communication hole connecting the vacuum chamber 12 and the water storage chamber 13. The vacuum chamber 1 is also provided with a drain hole communicating with the water storage chamber 13.

[0039] The drainage assembly includes a slide rod 2 slidably connected to the vacuum chamber 1. The slide rod 2 is provided with an upper piston 21 for opening or sealing the communication hole. The slide rod 2 is also provided with a lower piston 22 for opening or sealing the drainage hole. The drainage assembly also includes a drive mechanism for driving the slide rod 2 to reciprocate.

[0040] In the non-drainage state, the drive mechanism drives the slide bar 2 to move and causes the lower piston 22 to seal the drain hole first, and then the upper piston 21 opens the communication hole. In the drainage state, the drive mechanism drives the slide bar 2 to move and causes the upper piston 21 to seal the communication hole first, and then the lower piston 22 opens the drain hole.

[0041] Specifically, the water storage chamber 13 can be connected to an independent vacuum generator. After drainage is complete, when the slide rod 2 moves upward, and the lower piston 22 seals the drain hole while the upper piston 21 does not open the connecting hole, the vacuum generator can be used to evacuate the water storage chamber 13, making the air pressure in the water storage chamber equal to that in the vacuum chamber. Then, the slide rod 2 continues to move upward, causing the upper piston 21 to open the connecting hole and the lower piston 22 to seal the drain hole. At this time, the air pressure in the vacuum chamber 12 is equal to that in the water storage chamber 13, and the vacuum performance of the vacuum chamber 12 will not be affected.

[0042] Reference Figures 1 to 6 As shown, in some embodiments, the partition 11 and the vacuum chamber 1 are an integral structure, or the partition 11 is welded to the vacuum chamber 1.

[0043] The partition 11 is used to isolate the vacuum chamber 12 from the water storage chamber 13. The partition 11 should be effectively connected to the inner wall of the vacuum chamber 1. It can usually be welded or integrally structured to prevent gaps from forming between the partition 11 and the side wall of the vacuum chamber 1, so that the vacuum chamber 12 is less likely to fail.

[0044] In some embodiments, the partition 11 is provided with an upper cylinder 111 that cooperates with the upper piston 21. The upper cylinder 111 communicates with the connecting hole and is coaxially arranged with the connecting hole. The upper cylinder 111 is welded to the partition 11, or the upper cylinder 111 and the partition 11 are an integral structure.

[0045] The upper cylinder 111 is designed to increase the contact area between the upper piston 21 and the connecting hole, so that there is a large contact area between the upper piston and the side wall of the connecting hole, thereby making the vacuum chamber 12 less prone to leakage.

[0046] In some embodiments, the vacuum chamber 1 is provided with a lower cylinder that cooperates with the lower piston 22. The lower cylinder and the vacuum chamber 1 are an integral structure. The lower cylinder and the upper cylinder 111 are coaxially arranged. The lower cylinder communicates with the drain hole.

[0047] The lower cylinder is used to increase the contact area between the lower piston 22 and the drain hole to prevent leakage from the drain hole.

[0048] Reference Figures 1 to 6 As shown, in some embodiments, the partition 11 is arranged in the shape of a frustum inside the vacuum chamber 1, and the connecting hole is located at the lowest position of the partition 11.

[0049] The partition 11 can also be configured as a frustum shape. The specific shape of the partition 11 is not limited and can be reasonably determined according to the needs. It is understood that the water generated in the vacuum chamber 12 enters the water storage chamber 13 along the partition 11. Therefore, the partition 11 should be in an inclined state so that the partition 11 can quickly guide the water in the vacuum chamber 12 to the water storage chamber 13.

[0050] In some embodiments, the driving mechanism includes a base 23, to which a lead screw 231 is rotatably connected. A slide rod 2 has a threaded hole that mates with the lead screw 231. The base 23 has a guide post 232, and the slide rod 2 has a guide hole that mates with the guide post 232. The lead screw 231 can be rotatably connected to the base 23 in any manner, and a rolling bearing can be provided between the lead screw 231 and the base 23.

[0051] In some embodiments, the slide bar 2 is provided with a guide plate 233, and the guide hole is provided in the guide plate 233.

[0052] The guide plate 233 is welded to the slide rod 2; or, the guide plate 233 and the slide rod 2 are an integral structure.

[0053] Reference Figures 1 to 6 As shown, in some embodiments, the base 23 is also provided with a motor 234 that drives the lead screw 231 to rotate. The motor 234 is fixed to the base 23 by screws, and the output shaft of the motor 234 and the lead screw 231 are an integral structure.

[0054] In some embodiments, the vacuum chamber 1 is fixed to the base 23 by a support column 235, and a drainage groove 236 is provided between the motor 234 and the vacuum chamber 1. The drainage groove 236 is located directly below the drainage hole, and the water discharged from the drainage hole enters the drainage groove 236 under the action of gravity.

[0055] The drain groove 236 is used to guide the water discharged from the drain hole out, preventing the water discharged from the drain hole from entering the motor 234 and extending the service life of the motor 234.

[0056] In some embodiments, the drainage channel 236 may be welded to the support column 235.

[0057] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0058] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.
