Description

Technical Field

[0001] This utility model relates to the field of plastic production, and in particular to a water-cooled gravity flow device. Background Technology

[0002] A search of Chinese patents revealed CN210336791U, a cooling device for extrusion molding in plastic pipe production, addresses the problem of inconvenient adjustment of the cooling spray position during post-extrusion cooling of plastic pipes, resulting in poor cooling effect. The proposed solution includes a cooling water tank with movable guide rollers evenly spaced along its length. A top frame is fixed above the cooling water tank, and a movable rack is located below the top frame. One end of the movable rack has an adjustment component. A water inlet pipe is located above the top frame, and a nozzle is positioned below the top frame along the length of the movable rack. This invention features a novel structure. By adjusting the movement of the movable rack, the rotation of the rotating half-gear is adjusted, thereby adjusting the spray angle of the nozzle and ultimately the spray position. This allows for adjustment of the cooling spray position according to the actual production needs of the plastic pipe, resulting in better cooling performance.

[0003] Existing cooling devices lack filtration capabilities and typically cool materials using water. However, water contains impurities, and directly reusing the water during circulation negatively impacts the production quality of plastic strips. Frequent water replacement increases production costs and makes the devices inconvenient to use. Furthermore, the cooling water temperature rises during prolonged circulation, affecting cooling efficiency. Relying on natural heat dissipation further reduces cooling efficiency and makes it difficult to guarantee effective cooling. To address these issues, we propose a water-cooled gravity flow device. Utility Model Content

[0004] The purpose of this invention is to provide a water-cooled gravity flow device, which has the advantages of having a filtration function and being able to cool cooling water.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water-cooled gravity flow device, including a cooling tank, a conveyor belt and a water tank at the bottom of the cooling tank, one end of the conveyor belt being located inside the water tank, a water delivery mechanism being provided between the cooling tank and the water tank, a filter screen being slidably connected to the inner wall of the water tank, a cover plate being provided between the inner walls of the water tank, a slide rod being slidably connected to the inner wall of the cover plate, a toothed rod being bolted to the surface of the slide rod, a transmission gear being meshed on the surface of the toothed rod, and the transmission gear being rotatably connected to the inner wall of the cover plate, a snap-fit ​​connector being bolted to the surface of the slide rod, a snap-fit ​​hole being opened in the inner wall of the water tank, and the snap-fit ​​hole being snapped with the snap-fit ​​connector, a toggle block being bolted to the surface of the slide rod, and a spring being provided between the slide rod and the inner wall of the cover plate.

[0006] By adopting the above technical solution, the cooling water is filtered by setting a filter screen in the water tank, ensuring the quality of the cooling water. By moving the toggle block, the slide bar drives the rack to move, which in turn drives another rack to move, causing another slide bar to move. The movement of the slide bar drives the snap-fit ​​connector to move, and the snap-fit ​​connector disengages from the snap-fit ​​hole. The cover plate can then be removed, and the filter screen can be taken out for maintenance, thus facilitating the maintenance of the filter screen.

[0007] The present invention is further configured as follows: a fixed shell is bolted to the surface of the water tank, a motor is bolted to the bottom of the fixed shell, a first bevel gear is fixedly sleeved at the output end of the motor, a second bevel gear meshes with the surface of the first bevel gear, a rotating tube is fixedly sleeved at the axis of the second bevel gear, and the rotating tube is rotatably sleeved with the inner wall of the water tank, a stirring tube is connected to the surface of the rotating tube, an air jet hole is opened on the surface of the stirring tube, a fixed tube is rotatably sleeved with the inner wall of the rotating tube, and the fixed tube is fixedly sleeved with the inner wall of the fixed shell, and an air pump is connected to the other end of the fixed tube, and the air pump is bolted to the surface of the fixed shell.

[0008] By adopting the above technical solution, the first bevel gear is driven by the rotation of the motor, which in turn drives the second bevel gear to rotate. The rotation of the second bevel gear drives the rotating tube to rotate the stirring tube, thereby lowering the cooling water plate. The air pump fills the fixed tube with air, and the gas enters the stirring tube through the rotating tube and is ejected from the jet hole to cool the cooling water. This method can achieve the purpose of cooling the cooling water, ensure the cooling effect, and is convenient to use.

[0009] The present invention is further configured such that: the water delivery mechanism includes a circulating pump, the circulating pump is bolted to the inner wall of the water tank, the output end of the circulating pump is connected to a connecting pipe, the other end of the connecting pipe is connected to a water outlet pipe, and the water outlet pipe is bolted to the inner wall of the cooling tank.

[0010] By adopting the above technical solution and setting up a water delivery mechanism, it is convenient to circulate the cooling water.

[0011] The present invention is further configured such that a guide plate is bolted to the inner wall of the cooling tank.

[0012] By adopting the above technical solution and setting up a guide vane, the cooling effect is improved.

[0013] The present invention is further configured such that a protective shell is bolted to the surface of the fixed shell, and the air pump is located inside the protective shell.

[0014] By adopting the above technical solution, a protective shell is installed to protect the air pump.

[0015] The present invention is further configured such that a one-way valve is connected between the fixed pipe and the air pump.

[0016] By adopting the above technical solution, a one-way valve is installed to prevent cooling water from flowing out.

[0017] The present invention is further provided with a sealing gasket between the cover plate and the inner wall of the water tank.

[0020] By adopting the above technical solution, the connecting pipe is fixed by setting a fixing block to ensure stability.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model filters the cooling water by setting a filter screen in the water tank, ensuring the quality of the cooling water. By moving the toggle block, the slide rod drives the rack to move, which in turn drives another rack to move, causing another slide rod to move. The movement of the slide rod drives the snap-fit ​​connector to move, which disengages the snap-fit ​​connector from the snap-fit ​​hole. The cover plate can then be removed, and the filter screen can be taken out for maintenance, thus facilitating the maintenance of the filter screen.

[0023] 2. This utility model uses a motor to rotate a first bevel gear, which in turn drives a second bevel gear. The rotation of the second bevel gear causes the rotating tube to rotate, which in turn drives the stirring tube. This process lowers the cooling water plate, and an air pump fills the fixed tube with air. The air enters the stirring tube through the rotating tube and is ejected from the jet hole, thus cooling the cooling water. This method achieves the purpose of cooling the cooling water, ensures the cooling effect, and is convenient to use. Attached Figure Description
