Description

Technical Field

[0001] This utility model specifically relates to the field of energy heat pump technology, and more specifically to a high-temperature energy-saving heat pump device for a coating machine. Background Technology

[0002] A heat pump is a device that absorbs heat from a low-temperature heat source and releases it to a high-temperature heat source at a higher temperature. Its working principle is based on the reverse Carnot cycle. A liquid medium absorbs low-grade heat energy from the air and vaporizes in the evaporator. The vaporized medium is then compressed into a high-temperature, high-pressure gas by the compressor and enters the condenser. In the condenser, the refrigerant releases heat to a high-temperature heat source (such as indoor air or hot water), liquefies, and then passes through an expansion valve to reduce its pressure before re-entering the evaporator for the next cycle. Coating machines generate a large amount of heat during operation, which affects the temperature of the entire workshop. After processing, the materials in the coating machine need to be dried in an oven. The temperature around the oven is also relatively high, which also affects the working temperature of the coating machine processing workshop. To ensure a constant temperature inside the workshop, a heat exchange system is generally used to regulate the workshop temperature.

[0003] However, in practice, it has been noted that most coating machine workshops utilize heat exchange mechanisms for secondary use. However, due to the difficulty in storing heat, the recovered heat energy needs to be used immediately. Relying solely on heat exchangers cannot fully utilize all the heat, and heat loss during the heat exchange process can lead to insufficient heat temperature, rendering the recovered heat energy unusable. For example, coating machines also need to maintain a dry environment during operation, requiring the use of dehumidifiers. Common dryers rely on internal electric heating elements for heating, and then use fans to deliver hot air into the workshop. Since this process results in some temperature loss, a relatively high initial temperature is required. After the recovered heat energy is lost, the temperature cannot meet the requirements, thus preventing the direct use of the recovered heat energy and easily leading to its waste.

[0032] Among them, the water tank for storing heat energy is divided into a high-temperature pressurized water tank 11 and an insulated water tank 14, and the water pump is divided into an ultra-high temperature water pump 12 located between the high-temperature pressurized water tank 11 and the ultra-high temperature heat pump unit 13, and a high-temperature water supply pump 15 located between the ultra-high temperature heat pump unit 13 and the insulated water tank 14.

[0033] The ultra-high temperature water pump 12 and the high temperature water supply pump 15 are each set in pairs.

[0034] In this embodiment, the ultra-high temperature heat pump unit 13 has a high temperature pipe and a low temperature pipe.

Multiple heat sources supply heat energy simultaneously, and the recovered heat energy is stored in the insulated water tank 14, reducing the consumption of heat energy during use. Moreover, the compressor inside the ultra-high temperature heat pump unit 13 heats the heat energy to the required temperature and sends the heat energy to the coating machine oven 4 and dehumidifier 10 for use. The ultra-high temperature heat pump unit 13 can utilize low-grade heat sources, greatly improving energy utilization efficiency. Its energy conversion efficiency is high, and it is more energy efficient than traditional electric heating methods.

[0043] In this embodiment, the inlet of the ultra-high temperature water pump 12 is connected to the outlet of the high temperature pressurized water tank 11, and the outlet of the ultra-high temperature water pump 12 is connected to the inlet of the high temperature pipe inside the ultra-high temperature heat pump unit 1.

[0044] Furthermore, the outlets of the coating machine oven 4 and the dehumidifier 10 are connected to the inlet of the high-temperature pressurized water tank 11 through another drying and heating pipe 7, so that excess heat is circulated and sent to the high-temperature pressurized water tank 11 for storage, preventing heat energy from being wasted and playing an energy-saving role.

[0045] In this embodiment, the inlet of the high-temperature water supply pump 15 is connected to the outlet of the insulated water tank 14, and the outlet of the high-temperature water supply pump 15 is connected to the inlet of the low-temperature pipe inside the ultra-high temperature heat pump unit 13. The outlet of the low-temperature pipe inside the high-temperature water supply pump 15 is connected to the inlet of the fabric coating machine 5, the air compressor 8 and the chiller 9 through the waste heat recovery pipe 6.

[0046] More specifically, the outlets of the fabric coating machine 5, air compressor 8, and chiller 9 are connected to the inlet of the insulated water tank 14 through another waste heat recovery pipe 6, so as to recover the heat energy generated by the fabric coating machine 5, air compressor 8, and chiller 9 during operation and send it into the insulated water tank 14 for storage.

[0047] The working principle of this utility model is as follows: During operation, the heat energy generated by the fabric coating machine 5, air compressor 8, and chiller 9 is first recovered through the evaporator. The recovered heat energy is then stored in the insulated water tank 14 via the waste heat recovery pipe 6. Then, the high-temperature water pump 15 carries the heat energy from the medium in the insulated water tank 14 into the low-temperature pipe inside the ultra-high temperature heat pump unit 13. The compressor inside the ultra-high temperature heat pump unit 13 raises the heat source temperature, and the heated heat energy is then transferred to the high-temperature pipe. The medium that has lost heat energy then re-absorbs heat through the evaporators in the fabric coating machine 5, air compressor 8, and chiller 9, and the heat energy is then sent to the insulated water tank 14. The heat energy is stored in tank 14, forming a cycle. The ultra-high temperature water pump 12 sends the heat energy from the high temperature pressurized water tank 11 into the high temperature pipe of the ultra-high temperature heat pump unit 13. The compressor inside the ultra-high temperature water pump 12 heats the heat energy. The heated medium is then sent to the coating machine oven 4 and the dehumidifier 10 through the drying and heating pipe 7 for use. The remaining heat energy then flows back into the high temperature pressurized water tank 11 for storage, forming a cycle in the same way. The ultra-high temperature heat pump unit 13 can absorb low-temperature heat energy and convert it into stable high-temperature heat energy. Compared with traditional heating methods (electric heating, steam heating, etc.), it has lower operating energy consumption, a more stable operating environment, and more economical operating costs.
