Description

Technical Field

[0001] This utility model applies to the field of PVC pipe production technology, and particularly relates to a vacuum box water-air separator in a PVC pipe production line. Background Technology

[0002] Currently, the vacuum chamber is the main equipment in the PVC pipe production line that cools and shapes PVC pipe blanks at high temperatures. The vacuum environment of the vacuum chamber needs to be ensured by a vacuum pump. The vacuum pump removes the high-temperature gas containing a large amount of moisture from the vacuum chamber, thus creating a vacuum environment in the vacuum chamber.

[0003] However, in current vacuum chambers for separating moisture-containing gases, a hydrophobic membrane is installed inside the separator. During water-gas separation, water accumulates on the surface of the membrane, hindering the separation of water and air. During this accumulation, a large amount of water forms a film on the bottom surface of the hydrophobic membrane, obstructing its flow and reducing the rate at which high-temperature water vapor passes through. This, in turn, affects the overall separation rate of the high-temperature water vapor. Therefore, we propose a vacuum chamber water-gas separator for PVC pipe production lines. Utility Model Content

[0004] The main purpose of this invention is to provide a vacuum chamber water-air separator for PVC pipe production lines, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A vacuum chamber water-air separator in a PVC pipe production line includes a heat insulation frame, a hydrophobic membrane frame fixedly installed in the middle of the inner side of the heat insulation frame, a connecting bend pipe fixedly installed through the middle of the top of the heat insulation frame, a gas collection hood fixedly connected to the bottom of the connecting bend pipe, and an air inlet pipe fixedly installed through the bottom of the side of the heat insulation frame.

[0007] The heat insulation frame has rotating disks mounted on both sides inside, and each rotating disk has a transmission mechanism on its outer side, and each transmission mechanism has a tapping mechanism on its outer side.

[0008] As an optional solution to the technical solution of this application, the transmission mechanism includes a transmission frame and a stop rod. Rotating rods are rotatably mounted on both ends of the inner side of the insulation frame via sealed bearings, and the top edge of the rotating rod is fixedly connected to the outer side of the rotating disk. A stop rod is fixedly mounted on the outer side of each rotating disk. A rotating motor is fixedly mounted on both ends of the outer side of the insulation frame, and the side of the rotating motor's transmission shaft is fixedly connected to the top edge of the outer side of the rotating rod via a coupling. Connecting rods are rotatably mounted on the inner side of the insulation frame via sealed bearings. A connecting plate is fixedly mounted on the top edge of the side of each connecting rod. A transmission frame is fixedly mounted on the top edge of the side of each connecting plate. A sliding groove is opened inside each transmission frame, and the stop rod is slidably inserted into the sliding groove. A limit baffle is fixedly mounted on the top edge of the side of each stop rod away from the transmission disk.

[0009] By adopting the above technical solution, the rotating disk and the transmission frame are connected by actuation rod, which drives the tapping plate set at the top side of the transmission frame to move back and forth synchronously at the bottom of the hydrophobic membrane frame. This allows the tapping plate to tap the bottom surface of the hydrophobic membrane repeatedly, causing the bottom surface to vibrate and break up the water film on the surface. This prevents the water film from accumulating and affecting the flow rate of high-temperature water vapor, thereby improving the water vapor separation rate of the hydrophobic membrane for high-temperature water vapor.

[0010] As an optional solution to the technical solution of this application, a liquid guiding block is fixedly installed on the bottom inner side of the insulation frame, and a drain groove is opened on the bottom side of the insulation frame.

[0011] By adopting the above technical solution, the liquid can be discharged in a timely manner through the liquid draining tank under the structural action of the liquid guiding block and the liquid draining tank, thus avoiding the long-term accumulation of water and affecting the subsequent high-temperature water-gas separation rate.

[0012] As an optional solution to the technical solution of this application, the tapping mechanism includes a tapping plate, and a fixing block is fixedly installed on the top of the outer side of each transmission frame away from the connecting plate, and a tapping plate is fixedly installed on the top surface of each fixing block.

[0013] By adopting the above technical solution, and by setting a tapping plate on the outside of the transmission frame, the transmission frame is subjected to the connecting transmission action of the abutment rod, so that the tapping plate can reciprocate to tap the bottom surface of the hydrophobic film, causing the bottom surface to vibrate and then the water film on the surface is broken up by vibration.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The vacuum chamber water-air separator in the PVC pipe production line of this application, by setting rotatable rotating disks on both sides inside the insulation frame and setting abutting rods on the outside of the rotating disks, and by combining connecting rods and connecting plates to rotatably install the transmission frame on the outside of the rotating disks, and simultaneously sliding the abutting rods into the sliding grooves inside the transmission frame, allows the abutting rods to convert the rotation of the rotating disks into a pushing force on the transmission frame when the rotating disks rotate. This allows the abutting rods to move horizontally synchronously inside the sliding grooves, while the transmission frame can rotate around the connecting rods as the center. The transmission frame can then move vertically up and down synchronously, thereby driving the tapping plate set at the top of the side of the transmission frame to move up and down synchronously at the bottom of the hydrophobic membrane frame. This allows the tapping plate to tap the bottom surface of the hydrophobic membrane, causing vibration and breaking up the water film on its surface, preventing the water film from accumulating and affecting the flow rate of high-temperature water vapor, thereby improving the water-air separation rate of the hydrophobic membrane for high-temperature water vapor.

[0016] 2. The vacuum box water-air separator in the PVC pipe production line of this application has a triangular liquid guiding block at the bottom of the insulation frame and a drain trough on the side of the bottom of the insulation frame. The liquid guiding block guides and transports the water dripping from the bottom surface of the hydrophobic membrane frame in a timely and rapid manner, so that the water can be discharged through the drain trough in a timely manner, avoiding the long-term accumulation of water and affecting the subsequent high-temperature water-air separation rate.

[0021] like Figure 1-3As shown, this utility model provides a technical solution: a vacuum box water-air separator in a PVC pipe production line, wherein a hydrophobic membrane frame 11 is fixedly installed in the middle of the inner side of the insulation frame 1, a connecting bend 13 is fixedly installed through the middle of the top of the insulation frame 1, a gas collection hood 14 is fixedly connected to the bottom of the connecting bend 13, and an air inlet pipe 12 is fixedly installed through the bottom of the side of the insulation frame 1.

[0022] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a rotating rod 2 is rotatably mounted on both ends of the inner side of the insulation frame 1 through sealed bearings, and the top edge of the rotating rod 2 is fixedly connected to the outer side of the rotating disk 21. An abutment rod 26 is fixedly mounted on the outer side of each rotating disk 21. A rotating motor 29 is fixedly mounted on both ends of the outer side of the insulation frame 1, and the side of the drive shaft of the rotating motor 29 is fixedly connected to the top edge of the outer side of the rotating rod 2 through a coupling.

[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, the inner side of the insulation frame 1 is rotatably mounted with connecting rods 22 via sealed bearings. Each connecting rod 22 has a connecting plate 23 fixedly mounted on its top side. Each connecting plate 23 has a transmission frame 24 fixedly mounted on its top side. Each transmission frame 24 has a sliding groove 25 inside, and an abutting rod 26 is slidably inserted into the sliding groove 25. Each abutting rod 26 has a limit baffle 4 fixedly mounted on its top side away from the transmission disc. The side of the limit baffle 4 slides against the outer wall of the transmission frame 24, and the diameter of the limit baffle 4 is larger than the inner diameter of the sliding groove 25.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, the tapping mechanism includes a tapping plate 28. A fixing block 27 is fixedly installed on the top of the outer side of each transmission frame 24 away from the connecting plate 23, and the tapping plate 28 is fixedly installed on the top surface of each fixing block 27.

[0025] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown), a liquid guiding block 3 is fixedly installed on the bottom inner side of the insulation frame 1, and a drain groove 31 is opened on the bottom side of the insulation frame 1. The vertical cross section of the liquid guiding block 3 is a right triangle, and the top of the side of the liquid guiding block 3 is located below the outside of the drain groove 31.

[0026] During operation, high-temperature water vapor from the vacuum chamber in the PVC pipe production line is transported to the insulation frame 1 through the air inlet pipe 12. Then, the air inlet of the suction pump is connected to the connecting bend pipe 13. Under the action of the suction pump, the high-temperature water vapor accumulated inside the insulation frame 1 is extracted and passed through the hydrophobic membrane frame 11. The hydrophobic membrane inside the frame separates the air and water within the high-temperature water vapor, allowing the water to accumulate on the bottom surface of the frame. Simultaneously, the external control switch turns on the rotating motor 29, causing it to rotate and drive the rotating disk 21 to rotate synchronously inside the insulation frame 1. This synchronously drives the abutment rod 26 to move within the insulation frame 1. After internal rotation, the abutment rod 26 can move horizontally within the sliding groove 25. The abutment rod 26 can convert the rotational force of the rotating disk 21 into a vertical abutment force on the transmission frame 24. This allows the transmission frame 24 to move vertically up and down synchronously within the insulation frame 1 with the connecting rod 22 as the center. This, in turn, drives the tapping plate 28, which is located at the top of the side of the transmission frame 24, to move up and down synchronously at the bottom of the hydrophobic membrane frame 11. The tapping plate 28 can tap the bottom surface of the hydrophobic membrane repeatedly, causing it to vibrate and break up the water film on the surface, thus preventing the water film from accumulating and affecting the flow rate of high-temperature water vapor.
