Description

Technical Field

[0001] This utility model relates to the field of cooling water circulation technology, specifically to a vacuum cooling water recovery and circulation device. Background Technology

[0002] In the extrusion / extrusion machine of injection molding, vacuum pumping is a crucial process step. Plastic particles (especially recycled materials, hygroscopic materials, or materials that have not been fully dried) release moisture, gas, low-molecular-weight volatiles, and reaction byproducts during the heating and melting process. If these are not removed in time, they will cause bubbles, silver streaks, and voids inside the product, affecting its appearance and strength. Surface defects such as poor smoothness, haze, and scorch marks will appear, reducing the material density, leading to a decline in mechanical properties, affecting dimensional stability, and causing deformation.

[0003] However, during the production of the extrusion unit, the vacuum pump requires a large amount of cooling water to ensure production continuity. The traditional method of direct discharge into the ditch resulted in serious waste of water resources and did not meet the standards for energy conservation and emission reduction. Utility Model Content

[0004] The purpose of this utility model is to provide a vacuum cooling water recycling device to solve the above problems, recycle water resources, reduce costs, and achieve a dual improvement in energy conservation, emission reduction and economic benefits.

[0005] Technical Solution: This utility model provides a vacuum cooling water recovery and circulation device, including: a first support, a second support, a vacuum pump, a primary filter, a sedimentation tank, a return water tank, and a return water filtration device. The first support has an installation platform on top; the second support is located next to the first support, with a filtration platform above it; the vacuum pump is mounted on the installation platform, and has an inlet pipe and a return water pipe; the primary filter is mounted on the filtration platform and connected to the vacuum pump and the extrusion production host. The vacuum pump evacuates the extrusion production host, and the extracted gas, moisture, and impurities enter the primary filter, which has an outlet below it; the sedimentation tank is located at the bottom of the second support, directly opposite the outlet; there are two return water tanks, respectively located outside the first and second supports, connected by a water pipe, with the return water pipe connected in the middle; the return water filtration device is located outside the return water tanks and connected to them via a pipe.

[0006] Furthermore, in the aforementioned vacuum cooling water recovery and circulation equipment, the second support is higher than the first support.

[0007] Furthermore, in the aforementioned vacuum cooling water recovery and circulation equipment, the vacuum pump is connected to a clean water tank via an inlet pipe.

[0008] Furthermore, in the aforementioned vacuum cooling water recovery and circulation equipment, the primary filter is a mesh filter, with an internal filter screen for separating solid particulate impurities.

[0009] Furthermore, in the aforementioned vacuum cooling water recovery and circulation device, the water pipes are U-shaped and connected to the upper sides of the two return water tanks, with symmetrical positions.

[0010] Furthermore, in the aforementioned vacuum cooling water recovery and circulation equipment, the sedimentation tank is used to separate the oil and water in the waste liquid after filtering solid impurities.

[0011] Furthermore, in the aforementioned vacuum cooling water recovery and circulation equipment, the return water filtration device includes a filter box and a water pump. The filter box is connected to a return water tank on one side via a water pipe, and the water pipe is connected to the upper side of the return water tank. The water pump inlet is connected to the filter box via a pipe, and the water outlet is connected to a clean water tank via a pipe.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: The vacuum cooling water recycling equipment described in this utility model can meet the large cooling water demand of the vacuum pump to ensure production continuity and help maintain stable product quality. The cooling water used by the vacuum pump enters the return water tank, return water filter device, and clean water tank, and is then recycled back into the vacuum pump. The cooling water is recycled, saving resources and reducing costs. The cooling water that has been used once will be filtered and then returned to the clean water tank to enter the vacuum pump, ensuring that there are no impurities in the cooling water and that it will not affect the operation of the vacuum pump. When the vacuum pump is drawing vacuum, it will also carry away the water, dust, and oil from the extruder. Through the primary filter and sedimentation tank, solid impurities are filtered out and oil is separated, improving production stability and achieving a dual improvement in energy saving, emission reduction, and economic benefits. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of a vacuum cooling water recovery and circulation device according to the present invention.

[0014] In the diagram: First support 1, Second support 2, Vacuum pump 3, Primary filter 4, Sedimentation tank 5, Return water tank 6, Return water filtration device 7, Installation platform 11, Filtration platform 21, Inlet pipe 31, Return water pipe 32, Outlet 41, Water pipe 61, Filter box 71, Water pump 72. Detailed Implementation

[0015] Example 1 like Figure 1The vacuum cooling water recovery and circulation device shown includes: a first support 1, a second support 2, a vacuum pump 3, a primary filter 4, a sedimentation tank 5, a return water tank 6, and a return water filtration device 7. The first support 1 is mounted on an installation platform 11; the second support 2 is positioned next to the first support 1, with a filtration platform 21 above it; the vacuum pump 3 is mounted on the installation platform 11, and has an inlet pipe 31 and a return water pipe 32. The vacuum pump 3 is connected to the clear water tank via the inlet pipe 31; the primary filter 4 is mounted on the filtration platform 21 and is connected to the vacuum pump 6. Pump 3 is connected to the extrusion production host. The vacuum pump 3 evacuates the extrusion production host, and the extracted gas, moisture, and impurities enter the primary filter 4. An outlet 41 is located below the primary filter 4. The sedimentation tank 5 is located at the bottom of the second support 2, directly opposite the outlet 41. There are two return water tanks 6, located outside the first support 1 and the second support 2 respectively, connected by a water pipe 61. A return water pipe 32 is connected in the middle of the water pipe 61. The return water filtration device 7 is located outside the return water tank 6 and connected to it via a pipe. During vacuuming, the vacuum pump 3 draws moisture, dust, and oil from the raw materials into the primary filter 4 for solid particle filtration, separating the solid and liquid. The separated liquid flows into the sedimentation tank 5 for further oil separation. Cooling water from the clean water tank enters the vacuum pump 3 and flows out through the return water pipe 61 back to the return water tank 6. The return water filtration device 7 then extracts and filters the water from the return water tank 6 before returning it to the clean water tank.

[0016] In this embodiment, the primary filter 4 is a mesh filter, with an internal filter screen for separating solid particulate impurities. The liquid separated by gravity flows out from the outlet 41 and enters the sedimentation tank 5.

[0017] In this embodiment, the sedimentation tank 5 is used to separate oil and water in the waste liquid after filtering solid impurities.

[0018] Example 2 Based on Example 1, in this example, as... Figure 1 The illustrated vacuum cooling water recovery and circulation equipment includes a return water filtration device 7 comprising a filter box 71 and a water pump 72. The filter box 71 is connected to a return water tank 6 on one side via a water pipe, with the water pipe connected to the upper side of the return water tank 6. The inlet of the water pump 72 is connected to the filter box 71 via a pipe, and the outlet is connected to a clean water tank via a pipe. Water from the return water tank 6, after being used by the vacuum pump 3, is drawn out, filtered through the filter box 71 to remove impurities, and then pumped to the clean water tank by the water pump 72. The water then enters the vacuum pump 3 again, ensuring continuous production and forming a closed-loop cycle. This achieves efficient circulation of cooling water, reduces costs, and saves energy and reduces emissions.

[0019] In this embodiment, the second support 2 is higher than the first support 1.

[0020] In this embodiment, the water pipe 61 is U-shaped and connected to the upper side of the two return water tanks 6, with symmetrical positions. This meets the water demand of the vacuum pump 3, which requires a large amount of cooling water. The used cooling water enters the return water tank 6, ensuring that the liquid levels in the two return water tanks are equal. The side-mounted design prevents the water pipe 61 from becoming clogged and facilitates disassembly and maintenance.
