Description

Technical Field

[0001] This utility model relates to the field of pipeline production technology, and in particular to a PVC pipe production device. Background Technology

[0002] In the production process of PVC pipes, the process usually involves an extruder, followed by cooling in a cooling box, cutting by a rotary cutter, and finally traction by a traction machine to complete the production of PVC pipes.

[0003] However, existing cooling boxes are vacuum sizing water tanks, which mostly use an integral vacuum chamber and single-temperature cooling. However, after long-term operation, the water temperature will gradually rise, thus affecting the cooling effect. In addition, after the pipe is cooled by water, a large number of water droplets will adhere to its surface. These water droplets will be carried to the outside as the pipe moves and drip, thus affecting the operating environment of other equipment and making it inconvenient to use. Therefore, we propose a PVC pipe production device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing a PVC pipe production device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A water storage tank is located at the top of the support frame, and the outlet pipes are connected to the water storage tank.

[0007] The pipe can pass through three areas inside the vacuum sizing chamber, allowing for sequential cooling of different temperature zones, thus improving the cooling effect. Meanwhile, the cavity area at the rear is air-cooled, which can dry water droplets on the outer wall of the pipe, thus preventing water droplets from moving to the outside.

[0008] Preferably, cooling fans are provided on both sides of the rear end of the vacuum sizing chamber, and the cooling fans are connected to a separate area inside the vacuum sizing chamber.

[0009] The cooling fan can distribute the cooling inside the vacuum sizing chamber, dry the water droplets on the outer wall of the pipes, and improve the cooling effect through different cooling methods.

[0010] Preferably, the vacuum sizing chamber has two sets of regional filter housings, and then the bottom end of the filter housing is provided with a water inlet pipe, which is connected to the interior of the two sets of water storage tanks.

[0011] The water that has been sprayed inside the vacuum sizing chamber can be recycled back into the water storage tank through the filter shell and the inlet pipe, thus completing the water circulation and saving water consumption.

[0012] Preferably, the water storage tank is provided in two sets, and the water temperature inside the two sets of water storage tanks decreases sequentially according to the direction of the pipe entry;

[0013] The pipes can be cooled by using water at different temperatures, thus improving the cooling effect.

[0014] Preferably, the side wall of the filter housing is provided with a slot, and the side of the filter housing is provided with a mounting frame, which extends through the slot into the interior of the filter housing;

[0015] The mounting frame can filter impurities in the water, allowing the recycled water to be reused.

[0016] Preferably, the interior of the mounting frame is provided with a filter plate, an activated carbon adsorption plate and a ceramic filter element from top to bottom, and the filter plate, activated carbon adsorption plate and ceramic filter element are adapted to each other with the inner wall of the mounting frame.

[0017] It can filter impurities in water, thus improving the filtration effect.

[0018] Preferably, the filter housing has positioning blocks on both sides inside, and the positioning blocks are adapted to the two sides of the mounting frame.

[0019] The mounting frame can be positioned to improve its installation effect.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model can create three zones inside the vacuum sizing chamber, each with a different temperature, thereby improving the cooling effect of the pipe. At the same time, the cooling fan can dry the water droplets on the outer wall of the pipe, preventing them from moving to the outside.

[0022] 2. This utility model enables the filter housing and water inlet pipe to filter impurities in the water, thereby improving the performance of the circulating water inside the water tank.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4The illustrated PVC pipe production apparatus includes a vacuum sizing chamber 2 mounted on the top of a support frame 1 via a column. Multiple transparent covers 3, made of transparent glass, are movably mounted on the top of the vacuum sizing chamber 2 via a rotating shaft, allowing observation of the interior of the chamber. The interior of the vacuum sizing chamber 2 is divided into three areas by two sets of partition plates 5. A water storage tank 4 is then fixedly mounted on the top of the support frame 1, below the vacuum sizing chamber 2. Annular water pipes 6 are fixedly mounted on the sides of the partition plates 5 inside the vacuum sizing chamber 2. Spray pipes 7 are then fixedly mounted on the sides of the annular water pipes 6. Finally, an outlet pipe 8 is fixedly mounted at the bottom of the annular water pipes 6. Meanwhile, the bottom end of the water outlet pipe 8 extends into the interior of the water storage tank 4. The water storage tank 4 is equipped with a water pump, which can supply water from the water storage tank 4 into the interior of the annular water pipe 6 through the water outlet pipe 8, and then spray it through the spray pipe 7 for cooling. There are two sets of water storage tanks 4, and the two sets of water storage tanks 4 are respectively connected to two areas inside the vacuum sizing box 2. The water temperature inside the water storage tank 4 connected to the middle area inside the vacuum sizing box 2 is lower than the water temperature inside the other set of water storage tanks 4. Two sets of cooling fans 17 are fixedly installed in a separate area at the rear of the vacuum sizing box 2, so that one cooling fan 17 is the air inlet and the other cooling fan 17 is the air outlet, so that the cooling fans 17 can perform air cooling for the interior of the vacuum sizing box 2.

[0030] For a detailed description of the filter housing 9 in this embodiment, please refer to [link / reference]. Figure 3 and Figure 4 Subsequently, a filter housing 9 is fixedly installed at the bottom of the vacuum sizing chamber 2, so that the filter housing 9 is connected to the interior of the vacuum sizing chamber 2. At the same time, a water inlet pipe 10 is installed at the bottom of the filter housing 9, so that the water inlet pipe 10 is connected to the interior of the water storage tank 4, so that the water sprayed by the spray pipe 7 enters the interior of the water storage tank 4 through the filter housing 9 and the water inlet pipe 10 for circulation. Then, a slot 11 is opened on the side of the filter housing 9, and a mounting frame 13 is set on the side of the filter housing 9, so that the mounting frame 13 can be inserted into the interior of the filter housing 9 through the slot 11. At the same time, a filter plate 14, an activated carbon adsorption plate 15, and a ceramic filter element 16 are installed in the mounting frame 13 from top to bottom. At the same time, two sets of positioning blocks 12 are fixedly installed inside the filter housing 9, so that the two sets of positioning blocks 12 are located on both sides of the mounting frame 13, which can limit and support the mounting frame 13.

[0031] Working principle: When in use, the water inside the water storage tank 4 is immersed in the annular water pipe 6 through the water outlet pipe 8, and then sprayed into the vacuum sizing tank 2 through the spray pipe 7. After spraying, the water returns to the water storage tank 4 through the filter shell 9 and the water inlet pipe 10, so that the water forms a circulation. The extruded pipe enters from the end of the vacuum sizing tank 2 and then passes through three sets of areas for cooling, so that the cooling effect is better.

[0032] Meanwhile, the water inside the vacuum sizing chamber 2 enters the water storage tank 4 after passing through the filter housing 9 and the water inlet pipe 10. Then, the impurities in the water can be filtered by the filter plate 14, thereby preventing impurities from entering the water storage tank 4 and thus improving the effect of circulating cooling.
