Abstract
Description
Technical Field
[0001] This invention relates to the field of condensate drainage devices, and in particular to a VOCs fan condensate drainage device. Background Technology
[0002] When a VOCs fan is running, the gas flows through the fan casing. Moisture in the gas easily condenses inside the casing due to temperature changes and other factors, forming condensate. Simultaneously, the fan operation carries rust and dirt from the pipes into the casing. These residues and impurities, along with the condensate, flow through the drain pipe at the bottom of the casing into the condensate collection tank, easily accumulating and causing blockages. This prevents condensate from draining properly, causing it to remain inside the fan casing, affecting normal equipment operation, and in severe cases, leading to fan shutdown and environmental incidents. However, existing VOCs fan condensate drainage systems lack residue separation devices. Pipe residue in the condensate directly enters the drain pipe, easily causing blockages. The condensate remaining inside the fan casing can corrode and soak internal components, shortening the fan's lifespan, affecting its normal and safe operation, and increasing maintenance costs. Therefore, this application proposes a VOCs fan condensate drainage device to solve the above problems. Summary of the Invention
[0003] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a VOCs fan condensate drainage device. The technical solution it solves is as follows: A VOCs fan condensate drainage device includes a right horizontal pipe. The right horizontal pipe's outlet end is fixedly connected to the inlet end of a settling tank, and the settling tank's outlet end is fixedly connected to the inlet end of a left water pipe. The left water pipe is arranged obliquely with the left side higher than the right side. The right horizontal pipe is higher than the left water pipe. A mounting frame is coaxially fixedly connected to the inner wall of the left water pipe, and a filter screen is coaxially fixedly connected to the mounting frame. A support is fixedly connected to the outer wall of the left water pipe. The frame includes a drive assembly fixedly connected to the support, which drives a vertical moving rod. The vertical moving rod is fixedly connected to a connecting rod, which is fixedly connected to an end cap that movably abuts against the lower end of the settling tank. The end cap is coaxially fixedly connected to a vertical rod, which is coaxially fixedly connected to a cleaning assembly that slides against the inner wall of the settling tank. A spring plate fixedly fitted to the lower edge of the left water pipe and fixedly connected to the side wall of the filter screen is fitted into the spring plate. A fork is fixedly connected to the spring plate, and a longitudinal shaft is rotatably connected to the fork. A driven bevel gear meshing with the drive assembly is fixedly connected to the front end of the longitudinal shaft, and a vibration block is eccentrically fixedly connected to the longitudinal shaft.
[0004] Preferably, the drive assembly includes two guide vertical shafts fixedly connected to a bracket, with a support plate fixedly connected to the lower end of each guide vertical shaft. The bracket and the support plate are rotatably connected to the upper and lower ends of a bidirectional ball screw. The two guide vertical shafts are arranged symmetrically about the bidirectional ball screw. A screw nut is fitted onto the bidirectional ball screw. The right end of the screw nut is fixedly connected to a vertical moving rod. Short rods are fixedly connected to the front and rear ends of the screw nut, and each short rod is fixedly connected to a guide sleeve. The guide sleeves correspond one-to-one with the guide vertical shafts and are slidably connected. A driving bevel gear that meshes with a driven bevel gear is coaxially fixedly connected to the upper end of the bidirectional ball screw. A servo motor for driving the bidirectional ball screw is fixedly connected to the support plate.
[0005] Preferably, the cleaning assembly includes two support rods symmetrically arranged with respect to the vertical rod and fixedly connected to the upper end of the vertical rod. The two support rods are fixedly connected to a retaining sleeve arranged coaxially with the vertical rod. The retaining sleeve is fixedly connected to a cleaning plug ring that slides against the inner wall of the settling tank.
[0006] Preferably, the end cap is fixedly connected to a sealing ring that abuts against the lower end face of the settling tank, and the end cap is coaxially fixedly connected to a sealing ring that movably abuts against the inner wall of the settling tank, with the upper edge of the sealing ring having rounded corners.
[0007] Preferably, the left end of the left water pipe and the right end of the right horizontal pipe are respectively fixedly connected with connecting flanges. The beneficial effects of this invention are: This application is fixedly installed on the drainage path between the VOCs fan and the condensate collection tank via connecting flanges on the left water pipe and the right horizontal pipe. A settling tank is arranged between the left water pipe and the right horizontal pipe, which ensures that the condensate has sufficient buffer time for residue to settle, thereby effectively removing the residue mixed in the condensate. Furthermore, to ensure maximum residue removal, a left water pipe is provided on the left side of the settling tank. When the condensate flows through the settling tank and through the left water pipe, the left water pipe is arranged with a left-high and right-low orientation, so that as the residue flows with the condensate, it can slide down the pipe and return to the settling tank for sedimentation. A very small amount of residue that does not return is blocked by the filter screen. This application also includes a drive component, which can be periodically activated to clean the settling tank and the filter screen, thereby preventing residue accumulation and pipe blockage, and preventing condensate from remaining in the fan casing, which could cause corrosion, soaking, and other damage to the internal components of the fan.

[0016] The following is in conjunction with the appendix Figure 1-7 The specific embodiments of the present invention will be described in further detail.
[0017] In embodiment one, the technical solution is as follows: the left water pipe 3 is fixedly installed on the drainage path between the VOCs fan and the condensate collection tank via the connecting flange 32 on the right horizontal pipe 1. A settling tank 2 is arranged between the left water pipe 3 and the right horizontal pipe 1, which ensures that the condensate has sufficient buffer time for sedimentation, thereby effectively removing the residue mixed in the condensate. Furthermore, to ensure maximum residue removal, a left water pipe 3 is provided on the left side of the settling tank 2, thereby allowing the condensate to settle. When the water flows through the settling tank 2 and the left water pipe 3, the left water pipe 3 is arranged with the left side higher than the right side. As the residue and condensate pass through, the residue can slide down the pipe and return to the settling tank 2 for sedimentation. A very small amount of residue that does not return is blocked by the filter screen 5. In addition, this application also has a drive component 7. The drive component 7 can be started periodically to clean the settling tank 2 and the filter screen 5, thereby avoiding the accumulation of residue and the blockage of the pipe, and preventing the condensate from remaining in the fan casing, which would cause corrosion, soaking and other damage to the internal components of the fan.
[0018] In Example 2, based on Example 1, specifically, in this application, condensate enters the settling tank 2 through the right horizontal pipe 1. The condensate is buffered by the settling tank 2, allowing it to remain there for a certain period, thus causing the residue in the condensate to settle at the bottom of the settling tank 2. Furthermore, after most of the residue has settled in the settling tank 2, the condensate flows to the left water pipe 3. Since most of the residue has already settled at the bottom of the settling tank 2, only a very small amount of residue remains when the condensate flows through the left water pipe 3. The left water pipe 3 is arranged obliquely with the left side higher than the right side. Therefore, when the condensate flows through the left water pipe 3, the residue will slide down along the left water pipe 3 and return to the settling tank 2 for settling. Only a very small amount of residue that fails to return is blocked by the filter screen 5. Some of the blocked residue will slide back to the settling tank 2 for settling, while some will adhere to the filter screen 5.
[0019] To prevent excessive residue accumulation on the settling tank 2 and filter screen 5, which could cause pipe blockage, the drive assembly 7, i.e., the servo motor 25, needs to be periodically activated to rotate a set stroke. The servo motor 25 will drive the bidirectional ball screw 20, installed between the bracket 6 and the support plate 19, to rotate. The rotation of the bidirectional ball screw 20 will drive the screw nut 21 it mates with. The screw nut 21 is slidably connected to the guide shaft 18 via the guide sleeve 23 at the end of the short rod 22. Under the constraint of the sliding connection between the guide sleeve 23 and the guide shaft 18, the rotation of the bidirectional ball screw 20 will drive the screw nut 21 to move vertically reciprocally along the guide shaft 18, thereby fixing it in place. The vertical moving rod 8 will move vertically back and forth accordingly, and the connecting rod 9 and the end cap 10 fixedly connected to the connecting rod 9 will also move vertically back and forth accordingly. During the downward movement of the end cap 10, the end cap 10 will separate from the settling tank 2, thereby releasing the condensate and accumulated residue. During the vertical reciprocating movement of the end cap 10, the vertical rod 11 and the clamping sleeve 27 fixedly connected to the vertical rod 11 via the support rod 26 will also move vertically back and forth accordingly. The cleaning plug ring 28 fixedly connected to the clamping sleeve 27 will also move vertically back and forth along the inner wall of the settling tank 2, thereby cleaning the residue attached to the inner wall of the settling tank 2.
[0020] The servo motor 25 will automatically stop after rotating to the set stroke, and the end cover 10 will be as shown in the instruction manual. Figure 1 Generally, the seal re-abuts against the bottom of the settling tank 2, and the sealing ring 30 and sealing ring 29 on the end cap 10 will also abut against the corresponding parts of the settling tank 2, thereby ensuring a sealing effect on the bottom of the settling tank 2. Correspondingly, the other related components will also abut as per the instruction manual. Figure 1Normal reset. The servo motor 25 has a self-locking property, which ensures that the relevant components remain stable when it stops working.
[0021] During the rotation of the bidirectional ball screw 20 driven by the servo motor 25, the active bevel gear 24 will rotate synchronously with the bidirectional ball screw 20, and drive the driven bevel gear 16 meshing with it to rotate. Consequently, the longitudinal shaft 15 fixedly connected to the driven bevel gear 16 will also rotate on the fork 14. At the same time as the longitudinal shaft 15 rotates, the vibration block 17 fixedly connected to it will also rotate. Since the vibration block 17 is eccentrically fixedly connected to the longitudinal shaft 15, the rotation of the vibration block 17 will generate vibration energy, which will be transmitted to the filter screen 5 in the mounting frame 4 through the fork 14 and the spring plate 13, thereby causing the filter screen 5 to vibrate. As a result, the residue on the filter screen 5 will be separated from the filter screen 5 under the vibration effect, and the filter screen 5 can be cleaned.
[0022] In Example 3, based on Example 2, the height of the left water pipe 3 is lower than the height of the right horizontal pipe 1, so that condensate can flow smoothly from the right horizontal pipe 1 to the left water pipe 3. The upper edge of the sealing ring 30 is chamfered with a rounded corner 31, so that the sealing ring 30 can be inserted into and separated from the settling tank 2 during the vertical reciprocating movement of the end cover 10.
