[0004] The existing cooling water circulation device for injection molding workshop has the problems that the hot water generated by cooling is discharged through the water distribution cover, the water droplets discharged by the water distribution cover have large size and small contact area with air during falling, so that rapid cooling cannot be realized, and the direct discharge of hot steam will take away a large amount of water vapor, resulting in large cooling liquid loss. In order to solve the above problems, an energy-saving cooling water circulation system for injection molding workshop is provided. SUMMARY

[0007] (II) Technical scheme

[0008] To solve the above technical problems, the present invention provides an energy-saving injection molding workshop cooling water circulation system, including a water storage tank, a machine body, a hot water pipe and a drain pipe. The water storage tank is located at the bottom of the machine body. The hot water pipe is connected to the top of the side wall of the machine body. The drain pipe is connected to the bottom of the side wall of the water storage tank. A gas collection hood is connected to the top of the machine body. A water distribution hood is provided in the inner cavity of the gas collection hood. The water distribution hood consists of two sets, upper and lower. Each water distribution hood has a spray nozzle on its lower surface.

[0009] A waterproof motor is fixed to the bottom of the inner cavity of the machine by a bracket, and the power output end of the waterproof motor is connected to a blade for blowing air upwards.

[0010] A cooling cylinder is fitted onto the surface of the drain pipe.

[0011] Preferably, the top surface of the water distribution cover is provided with conical water-guiding protrusions for guiding water flow.

[0012] Preferably, an air pump is installed on the top surface of the machine body, and the exhaust end of the air pump is connected to an air guide pipe.

[0013] Preferably, the ends of the hot water pipes are connected to the water distribution cover, and the connection points between the two ends of the cooling cylinder and the drain pipe are closed structures.

[0014] Preferably, the end of the air guide pipe away from the air pump is connected to the cooling cylinder, and a return pipe is provided below the cooling cylinder, with both ends of the return pipe connected to the water storage tank and the cooling cylinder respectively.

[0015] Preferably, the inner cavity of the machine body is provided with angled packing for guiding the falling water, and an air inlet is provided at the connection between the water storage tank and the machine body.

[0018] The above-described technical solution of the present invention has the following beneficial technical effects:

[0019] 1. In this invention, hot water is sprayed out in the form of small water droplets through a spray head. The water distribution cover consists of two sets, upper and lower, which can increase the number of spray heads to ensure water output. By reducing the volume of the discharged water droplets, the falling water droplets are guided by the angled packing. During the falling process, the waterproof motor drives the blades, which blow air upwards, increasing the contact area and time between the hot water and the air. The cooled water is then extracted through a drain pipe, thereby improving the cooling efficiency of the hot water and reducing energy consumption.

[0020] 2. In this invention, the cooled water source is extracted through the drain pipe, thereby improving the cooling efficiency of hot water and reducing energy consumption. The hot steam on the top of the machine can be drawn away by the air pump and the hot steam is injected into the cooling cylinder through the air guide pipe. The surface temperature of the drain pipe decreases, and the hot steam will condense when it comes into contact with the surface of the drain pipe. The condensate flows into the water storage tank through the return pipe, and the gas is discharged through the exhaust pipe, which can reduce water loss and make it more energy-efficient.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0030] like Figures 1-6As shown, the present invention proposes an energy-saving cooling water circulation system for injection molding workshops, including a water storage tank 1, a machine body 2, a hot water pipe 3, and a drain pipe 4. The water storage tank 1 is located at the bottom of the machine body 2. The hot water pipe 3 is connected to the top of the side wall of the machine body 2. The drain pipe 4 is connected to the bottom of the side wall of the water storage tank 1. A gas collection hood 12 is connected to the top of the machine body 2. A water distribution hood 5 is provided in the inner cavity of the gas collection hood 12. The water distribution hood 5 consists of two sets, upper and lower. Each water distribution hood 5 has a spray nozzle 6 on its lower surface.

[0031] A waterproof motor 10 is fixed to the bottom of the inner cavity of the body 2 by a bracket, and the power output end of the waterproof motor 10 is connected to a blade 11 for blowing air upward.

[0032] The hot water pipe 3 is connected to the water distribution cover 5 at both ends.

[0033] It should be noted that the hot water pipe 3 is connected to the cooling structure of the injection molding equipment. The hot water generated by the injection molding equipment is discharged through the hot water pipe 3 to the water distribution hood 5 at the top of the inner cavity of the machine body 2. The hot water is sprayed out in the form of small water droplets through the spray nozzles 6. The water distribution hood 5 consists of two sets, upper and lower, which can increase the number of spray nozzles 6 to ensure the water output. By reducing the volume of the discharged water droplets, the falling water droplets are guided by the angled packing 8. During the falling process, the waterproof motor 10 drives the paddle 11. The paddle 11 blows the air upward, which can increase the contact area and time between the hot water and the air. The cooled water source is extracted through the drain pipe 4, thereby improving the cooling efficiency of the hot water and reducing energy consumption.

[0034] In this embodiment, as Figure 4 As shown, the top surface of the water distribution cover 5 is provided with conical water guiding protrusions 7 for guiding water flow.

[0035] It should be noted that the conical water-guiding protrusion 7 can guide the falling water droplets.

[0036] In this embodiment, as Figure 5 and Figure 6 As shown, an air pump 13 is installed on the top surface of the body 2. The exhaust end of the air pump 13 is connected to an air guide pipe 14. A cooling cylinder 15 is sleeved on the surface of the drain pipe 4. The connection between the two ends of the cooling cylinder 15 and the drain pipe 4 is a closed structure. The end of the air guide pipe 14 away from the air pump 13 is connected to the cooling cylinder 15. A return pipe 17 is provided below the cooling cylinder 15. The two ends of the return pipe 17 are connected to the water storage tank 1 and the cooling cylinder 15 respectively. The end of the cooling cylinder 15 away from the return pipe 17 is connected to an exhaust pipe 16 for gas discharge.

[0037] It should be noted that the cooled water is drawn out through the drain pipe 4, thereby improving the cooling efficiency of hot water and reducing energy consumption. The hot steam on the top of the unit 2 can be drawn away by the air pump 13 in conjunction with the air collection hood 12, and the hot steam is injected into the cooling cylinder 15 through the air guide pipe 14. The surface temperature of the drain pipe 4 decreases, and the hot steam will condense when it comes into contact with the surface of the drain pipe 4. The condensate flows into the water storage tank 1 through the return pipe 17, and the gas is discharged through the exhaust pipe 16, which can reduce water loss and make the use more energy-efficient.

[0038] In this embodiment, as Figure 3 As shown, the inner cavity of the body 2 is provided with an angled packing 8 for guiding the falling water, and an air inlet 9 is provided at the connection between the water storage tank 1 and the body 2.

[0039] It should be noted that the angled packing 8 can guide the falling water droplets to increase the contact area and time between the water droplets and the air, while the air inlet 9 can allow outside air to enter the body 2.

[0040] In this embodiment, as Figure 2 As shown, a water injection pipe 18 is connected to the side wall of the water storage tank 1, and an automatic water injection valve 19 is connected to the end of the water injection pipe 18.

[0041] It should be noted that by using the water injection pipe 18 in conjunction with the automatic water injection valve 19, the water in the water storage tank 1 can be automatically replenished after water loss.

[0042] The working principle and usage process of this invention: The hot water pipe 3 is connected to the cooling structure of the injection molding equipment. The hot water generated by the cooling of the injection molding equipment is discharged through the hot water pipe 3 to the water distribution cover 5 at the top of the inner cavity of the machine body 2. The hot water is sprayed out in the form of small water droplets through the spray nozzles 6. The water distribution cover 5 consists of two sets, upper and lower, which can increase the number of spray nozzles 6 to ensure the water output. By reducing the volume of the discharged water droplets, the falling water droplets are guided by the angled packing 8. During the falling process, the waterproof motor 10 drives the paddle 11, and the paddle 11 blows the air upward. This increases the contact area and time between hot water and air. The cooled water is extracted through the drain pipe 4, thereby improving the cooling efficiency of hot water and reducing energy consumption. The air pump 13, in conjunction with the air collection hood 12, can draw away the hot steam from the top of the unit 2 and inject the hot steam into the cooling cylinder 15 through the air guide pipe 14. The surface temperature of the drain pipe 4 decreases, and the hot steam will condense when it comes into contact with the surface of the drain pipe 4. The condensate flows into the water storage tank 1 through the return pipe 17, and the gas is discharged through the exhaust pipe 16, which can reduce water loss and make the use more energy-efficient.
