Description

Technical Field

[0001] This utility model relates to the field of mold temperature controller technology, specifically a gas-fired mold temperature controller with energy-saving function. Background Technology

[0002] A gas-fired mold temperature controller is an industrial temperature control device that uses gas combustion as a heat source to control the temperature of molds or other equipment. It has the ability to heat up rapidly to meet the timely temperature change requirements of different production stages. For example, in the injection molding process, it can quickly heat the mold to the required temperature, improving production efficiency. The gas-fired mold temperature controller generates high-temperature flames and hot flue gas by burning gas (such as natural gas, liquefied petroleum gas, etc.). This heat is transferred to the heat transfer medium through a heat exchanger. Common heat transfer media include heat transfer oil and water. After absorbing heat, the heat transfer medium's temperature rises, and then it is transported to the heating channel of the mold or other equipment through a circulating pump, transferring the heat to the mold and raising its temperature.

[0003] Patent document CN219769037U discloses a gas-fired intelligent mold temperature controller, which includes a mold temperature controller housing, an oil tank on the top of the housing, an oil inlet pipe fixedly connected to the bottom of the oil tank, and a heating cylinder and an oil pump inside the housing. This invention has the following advantages and effects: after the heated heat transfer oil is recovered through the oil outlet pipe, the hot oil will circulate back through the return oil pipe, passing through the interior of the cooling tank where it is cooled by the circulating cooling water. After the initially cooled heat transfer oil is pumped into the return pipe, the return oil cylinder protects its exterior, reducing the rate of temperature change and ensuring safer recovery. Furthermore, when needed, the oil tank and the oil inlet pipe can work together to replenish the heating cylinder with heat transfer oil, preventing insufficient oil from affecting the efficiency of constant temperature operation.

[0004] However, the aforementioned published literature on a gas-fired intelligent mold temperature controller mainly considers preventing insufficient oil volume from affecting the efficiency of constant temperature operation and the inconvenience of heat recovery and utilization.

[0005] In view of this, it is necessary to develop energy-saving mechanisms that can recover and utilize heat to achieve energy-saving effects. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves energy-saving effect by installing an energy-saving mechanism to recover and utilize heat. Existing methods require the recovery and cooling of the medium after heating the outside environment. Directly cooling the medium will lead to heat loss. Therefore, it is necessary to recover and utilize the heat of the medium during recovery to achieve energy-saving effect and reduce energy consumption. First, the first solenoid valve works to allow the internal flow of the conveying pipe. When the medium flows in the return oil pipe, the medium enters the conveying pipe and is transported to the heating box through the threaded groove.

At this time, heat conduction heats up the liquid in the heating box. The heat medium in the heating pipe will finally flow to the return oil pipe for recovery. When it is necessary to discharge the liquid in the heating box, the second solenoid valve works to allow the internal flow of the discharge end to discharge the liquid. 2. This utility model treats emitted flue gas by installing a flue gas treatment mechanism. When gas is burned, a certain amount of flue gas is generated, and direct emission of flue gas will pollute the environment. Therefore, this needs to be improved. First, the flue gas filter frame is twisted to fix the installation threaded cylinder into the installation threaded ring. When the flue gas inside the combustion chamber is discharged through the exhaust pipe, it is filtered by the activated carbon plate, thereby filtering the flue gas. At the same time, the flue gas has a certain temperature. If heat utilization is required, it is connected to the outside pipeline through the connecting flange, and the filtered flue gas is transported for heat energy utilization.

The end is equipped with a return oil pipe 12. First, the flange pipe 4 is used to connect to the external gas supply equipment, and then the gas enters the combustion chamber 6. The oil supply pump 3 is used to supply oil (heat transfer medium, such as heat transfer oil) to the hot oil chamber 7. The oil supply amount is also a fixed value. The combustion chamber 6 heats the medium in the hot oil chamber 7. Then, the oil supply pipe 8 heats the equipment (such as wood industry (plywood hot pressing), textile industry (fabric drying) and paper industry (paperboard drying)). After completion, the medium needs to be recovered. The return oil pump 9 works and the return oil pipe 12 recovers the medium and cools it through the cooling pipe in the cooling box 10, and returns it to the hot oil chamber 7, thus completing the work.

[0021] Please see Figure 2 and Figure 3The outer wall of the mold temperature controller housing 1 is equipped with an energy-saving mechanism for heat recovery and utilization to achieve energy-saving effects.

A conveying pipe 18 is installed at the bottom of the oil return pipe 12, and a first solenoid valve 19 is installed on the inner wall of the conveying pipe 18. The heating tube 20 is installed at the bottom of the silver heat-conducting plate 17, and one end of the conveying pipe 18 extends into the interior of the heating tube 20, and one end of the heating tube 20 extends into the interior of the oil return pipe 12. The bottom of the heating box 13 is equipped with a discharge end 21, and a second solenoid valve 22 is installed on the inner wall of the discharge end 21. Existing systems require the recovery and cooling of the medium after heating the external environment, while direct Cooling the medium directly leads to heat loss, so it is necessary to recover and utilize the heat of the medium during recycling to achieve energy saving and reduce energy consumption. First, the first solenoid valve 19 operates to allow flow inside the delivery pipe 18. When the medium flows inside the return oil pipe 12, the medium enters the delivery pipe 18 and is transported to the heating box 13 through the threaded inlet 14. The threaded top cover 15 seals the threaded inlet 14. At this time, the recovered heat medium is transported to the heating pipe 20 through the flow inside the delivery pipe 18. The outer wall of the heating pipe 20 is in contact with the outer wall of the silver heat-conducting plate 17, and the heating pipe 20 is also made of a material with good thermal conductivity. At this time, heat conduction heats up the liquid in the heating box 13. The heat medium in the heating pipe 20 will finally flow back to the return oil pipe 12 for recycling. When it is necessary to discharge the liquid in the heating box 13, the second solenoid valve 22 operates to allow flow inside the discharge end 21, and the liquid is discharged.

[0022] Please see Figure 2 and Figure 4The outer wall of the mold temperature controller housing 1 is equipped with a flue gas treatment mechanism for treating the emitted flue gas. The flue gas treatment mechanism includes an exhaust pipe 23. The exhaust pipe 23 is installed on the outer wall of the mold temperature controller housing 1, and one end of the exhaust pipe 23 extends into the interior of the combustion chamber 6. A threaded ring 24 is installed on the top of the exhaust pipe 23. A threaded cylinder 25 is installed on the inner wall of the threaded ring 24. A flue gas filter frame 26 is installed on the outer wall of the threaded cylinder 25. An anti-slip pad 27 is installed on the outer wall of the flue gas filter frame 26. An activated carbon plate 28 is installed on the inner wall of the flue gas filter frame 26. A surrounding pipe 29 is installed, and a connecting flange 30 is installed on the outer wall of the surrounding pipe 29. When the gas is burned, a certain amount of flue gas is generated. Direct emission of the flue gas will pollute the environment, so this needs to be improved. First, the flue gas filter frame 26 is twisted to fix the mounting threaded cylinder 25 into the mounting threaded ring 24. When the flue gas inside the combustion chamber 6 is discharged through the exhaust pipe 23, it is filtered by the activated carbon plate 28, thereby filtering the flue gas. At the same time, the flue gas has a certain temperature. If heat needs to be utilized, the connecting flange 30 is used to connect to the external pipeline, and the filtered flue gas is transported for heat energy utilization.

[0023] Working principle: First, flange pipe 4 is used to connect to the external gas supply equipment, so the gas enters the combustion chamber 6. Oil pump 3 supplies oil (heat transfer medium, such as heat transfer oil) to the hot oil chamber 7, with a fixed supply rate. Combustion chamber 6 heats the medium in hot oil chamber 7, and then the medium is heated through oil supply pipe 8 to equipment used in industries such as wood processing (plywood hot pressing), textile processing (fabric drying), and papermaking (paperboard drying). After completion, the medium needs to be recovered. This is achieved through the operation of return oil pump 9 and return oil pipe 12, which recovers the medium and facilitates its circulation. The cooling pipes in the cooling tank 10 cool the medium and return it to the hot oil chamber 7, thus completing the work. Existing systems require the medium to be recovered and cooled after heating the external environment, but directly cooling the medium leads to heat loss. Therefore, it is necessary to recover and utilize the heat from the medium during recovery to achieve energy saving and reduce energy consumption. First, the first solenoid valve 19 operates, allowing flow inside the delivery pipe 18. When the medium flows inside the return oil pipe 12, it enters the delivery pipe 18 and is transported to the desired liquid level via the threaded inlet 14. In the heating chamber 13, the threaded top cover 15 seals the threaded groove 14. At this time, the internal flow of the conveying pipe 18 transports the recovered heat medium to the heating pipe 20. The outer wall of the heating pipe 20 is in contact with the outer wall of the silver heat-conducting plate 17, and the heating pipe 20 is also made of a material with good thermal conductivity. Heat conduction then heats the liquid in the heating chamber 13. The heat medium in the heating pipe 20 eventually flows to the return oil pipe 12 for recovery. When it is necessary to discharge the liquid from the heating chamber 13, the second solenoid valve 22 operates, causing the internal flow of the discharge end 21 to... If the gas is discharged directly, the liquid will be discharged. When the gas is burned, it will produce a certain amount of flue gas. Direct emission of flue gas will pollute the environment, so this needs to be improved. First, twist the flue gas filter frame 26 to fix the installation threaded cylinder 25 into the installation threaded ring 24. When the flue gas inside the combustion chamber 6 is discharged through the exhaust pipe 23, it is filtered by the activated carbon plate 28. At the same time, the flue gas has a certain temperature. If heat needs to be utilized, it is connected to the outside pipeline through the connecting flange 30, and the filtered flue gas is transported for heat energy utilization.
