Description

Technical Field

[0001] This utility model relates to the technical field of rubber vulcanization equipment, specifically to a waste heat recovery device for a mold temperature controller used in rubber vulcanization. Background Technology

[0002] In the existing rubber vulcanization process, the mold temperature controller needs to provide a stable temperature for the vulcanization mold through a high-temperature medium. The high-temperature medium after heat exchange needs to be cooled and recycled. During the cooling process, waste heat is directly discharged.

[0003] When existing steam-type mold temperature controllers are in use, a large amount of moisture is carried into the rubber vulcanization equipment along with the high-temperature steam. This not only affects the quality of rubber vulcanization but also easily causes a large amount of moisture loss, requiring a large amount of water replenishment. Furthermore, the moisture carried by the high-temperature steam contains a large amount of heat, and a large amount of waste heat is lost during the cooling process, which not only increases resource consumption but also causes the working environment to continuously heat up, making it inconvenient to recover and reuse the waste heat. Therefore, it is necessary to design a waste heat recovery device for mold temperature controllers used in rubber vulcanization to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a waste heat recovery device for a mold temperature controller used in rubber vulcanization, so as to solve the problems mentioned in the background art.

The front and rear side walls of the steam-water separation box are fixedly connected to baffles. A metal mesh pad is fixedly connected to the upper inner side of the steam-water separation box. An electric drain valve is sealed at the middle position of the lower end of the steam-water separation box. A condensate recovery pipe is sealed at the lower end of the electric drain valve. A heat exchange spiral tube is attached to the outer side of the condensate recovery pipe. A pressurization pipe is sealed to the upper right end of the heat exchange spiral tube, and an air pump is sealed to the right end of the pressurization pipe.

[0006] Preferably, the right end of the steam-water separator is sealed with an air inlet flange, which is sealed to the steam pipe; the left end of the steam-water separator is sealed with an exhaust flange, which is sealed to the rubber vulcanizing equipment; and both the air inlet flange and the exhaust flange are provided with flange insulation sleeves on their outer sides.

[0009] Preferably, the lower end of the air pump is sealed with an air inlet pipe, and the upper end of the air pump is fixedly connected with a mounting base, which is fixedly connected to the gas-water separator.

[0010] Preferably, the outlet end of the heat exchange spiral tube is sealed to the rubber storage box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The waste heat recovery device of the mold temperature controller for rubber vulcanization can adsorb moisture from low-speed flowing high-temperature steam through the action of metal mesh pads, and can block moisture from high-speed flowing steam through the action of baffles, so that the moisture can condense on the surface of the baffles, thereby improving the water-vapor separation effect of high-temperature steam. The collected high-temperature condensate can enter the boiler for water replenishment through the condensate recovery pipe, which can significantly reduce energy consumption.

[0016] Example 1

[0017] Please refer to Figure 1-4 As shown, this utility model provides a waste heat recovery device for a mold temperature controller for rubber vulcanization, including a steam-water separation box 1 and an electric drain valve 4 at the lower end of the steam-water separation box 1 for draining water. Baffles 2 are fixedly connected to the front and rear side walls of the steam-water separation box 1. The baffles 2 can intercept moisture in the high-speed flowing high-temperature steam. A metal mesh pad 3 is fixedly connected to the upper inner side of the steam-water separation box 1. The metal mesh pad 3 can adsorb moisture in the low-speed flowing high-temperature steam. An electric drain valve 4 is sealed at the middle position of the lower end of the steam-water separation box 1. A condensate recovery pipe 5 is sealed at the lower end of the electric drain valve 4. The opening and closing of the electric drain valve 4 can be automatically controlled by the PLC controller in the mold temperature controller, so that the intercepted high-temperature condensate can be sent to the boiler makeup water through the condensate recovery pipe 5, which greatly reduces energy consumption. A heat exchange spiral tube 6 is attached to the outer side of the condensate recovery pipe 5. The heat exchange spiral tube 6 can exchange heat in the condensate recovery pipe 5. A pressurized gas pipe 7 is sealed to the upper right end of the heat exchange spiral tube 6. An air pump 8 is sealed to the right end of the pressurized gas pipe 7. The start of the air pump 8 enables the pressurized gas pipe 7 to send gas into the heat exchange spiral tube 6 to realize the heat transfer process.

[0018] Specifically, the right end of the steam-water separator 1 is sealed with an inlet flange 9, which is sealed to the steam pipe. The left end of the steam-water separator 1 is sealed with an exhaust flange 10, which is sealed to the rubber vulcanizing equipment. Both the inlet flange 9 and the exhaust flange 10 are provided with flange insulation sleeves 11. The flange insulation sleeves 11 can insulate the connection points on the left and right sides, reducing the loss of high-temperature steam temperature.

[0019] Specifically, the outer surface of the gas-water separator 1 is provided with a heat insulation sleeve 12, which can insulate the gas-water separator 1 and prevent a large amount of heat loss from the high-temperature condensate trapped inside.

[0020] Specifically, a spiral groove 13 is provided on the outer side of the condensate recovery pipe 5. The spiral groove 13 increases the contact area between the condensate recovery pipe 5 and the heat exchange spiral tube 6, thereby improving the heat exchange efficiency. An insulation pipe 14 is provided on the outer side of the condensate recovery pipe 5. The inner side of the insulation pipe 14 is in close contact with the outer side of the heat exchange spiral tube 6. The insulation pipe 14 reduces the heat loss during the condensate and waste heat recovery process.

[0021] Specifically, the lower end of the air pump 8 is sealed with an air inlet pipe 15, and the upper end of the air pump 8 is fixedly connected with a fixed mounting base 16. The fixed mounting base 16 is fixedly connected to the steam-water separator 1. Through the air inlet pipe 15, external gas can be sent into the heat exchange spiral tube 6 to realize gas circulation and accelerate the waste heat recovery speed.

[0022] Specifically, the outlet end of the heat exchange spiral tube 6 is sealed to the rubber storage box. The connection between the heat exchange spiral tube 6 and the rubber storage box allows waste heat to enter the rubber storage box, achieving preliminary preheating treatment of the internal rubber and enabling effective utilization of the waste heat.

[0023] Working Principle: This utility model is a waste heat recovery device for a mold temperature controller used in rubber vulcanization. When recovering waste heat from the mold temperature controller, the inlet flange 9 is first connected to the end of the steam pipe of the mold temperature controller, and the exhaust flange 10 is connected to the rubber vulcanization equipment. After installation, high-temperature steam enters the steam-water separator 1 through the inlet flange 9. The staggered baffles 2 and metal mesh 3 can block or adsorb moisture from the flowing high-temperature steam. The baffles 2 block moisture from the high-speed flowing high-temperature steam, while the metal mesh 3 adsorbs moisture from the low-speed flowing high-temperature steam. This effectively improves the water-vapor separation effect of the high-temperature steam, allowing the condensed high-temperature condensate to fall into the lower part of the steam-water separator 1. Opening the electric drain valve 4 allows high-temperature condensate to be recycled back into the boiler through the condensate recovery pipe 5 for water replenishment, thereby significantly reducing energy consumption. During the steam-water separation process, the flange insulation sleeve 11 and the box insulation sleeve 12 effectively reduce heat loss. During the high-temperature condensate recovery process, the spiral groove 13 allows the heat exchange spiral tube 6 to be embedded, increasing the heat exchange contact area and thus improving the heat exchange effect. The insulation pipe 14 on the outside reduces the heat loss of the heat exchange spiral tube 6. The start of the air pump 8 allows air to enter through the air inlet pipe 15, and the gas is sent into the heat exchange spiral tube 6 through the pressurized air pipe 7, thereby heating the incoming gas and sending it into the rubber storage equipment to preheat the rubber, so that the waste heat can be fully utilized.
