[0033] Reference Figures 1 to 8 The utility model discloses a mold heating and heat supply system, which consists of three parts, including a garbage cracking gas generating device, an oil barrel heating device and a temperature regulating oil separation device. The garbage cracking gas generating device mainly converts garbage into combustible gas; the oil barrel heating device utilizes the combustion of combustible gas to heat the oil; and the temperature regulating oil separation device then supplies the oil to the mold for heating.

[0034] like Figures 1 to 3 As shown, the garbage cracking gas generating device includes a furnace body 1 and a feed hopper. The furnace body 1 is square and preferably made of stainless steel. A sealing plate 4 capable of closing the feed pipe 3 is provided in the feed pipe 3 of the feed hopper. A mesh plate 5 is provided in the furnace body 1. The mesh plate 5 divides the furnace body 1 into a cracking chamber 6 and an ash storage chamber 7. The feed pipe 3 is connected to the cracking chamber 6. A furnace opening and a furnace cover 8 for closing the furnace opening are provided on the top of the cracking chamber 6. A gas pipe 9 and an air pipe 10 connected to the cracking chamber 6 are provided on the furnace body 1.

[0035] The working principle of the above structure is: when feeding is needed, the sealing plate 4 is opened, so that the waste can enter the cracking chamber 6 from the feeding pipe 3, and the combustion igniter installed on the furnace body 1 ignites the waste in the cracking chamber 6, and the air duct 10 is connected to the fan, and the fan blows the outside air into the cracking chamber 6, and by controlling the amount of air entering the cracking chamber 6, the waste starts to burn incompletely, thereby generating a large amount of combustible gas, which is supplied to the subsequent oil barrel heating device as fuel to heat the hot oil through the gas pipeline 9, and finally the residue of the waste falls into the ash storage chamber 7 below through the mesh plate 5 and is manually cleaned. The furnace mouth is used as the entrance for maintenance or cleaning the cracking chamber 6, and is usually sealed by the furnace cover 8, and the furnace cover 8 is preferably made of stainless steel. The garbage waste of this application is not ordinary household garbage, but mainly some natural polymer material waste such as wood, paper, cotton, linen, and wool.

[0036] As shown in the figure, as a further structure, the furnace body 1 is provided with a shell 11, and a closed circulation channel 12 is formed between the shell 11 and the furnace body 1, the air duct 10 is arranged on the shell 11 and communicates with the circulation channel 12, and the furnace body 1 is annularly provided with uniform air holes communicated with the circulation channel 12, and the air blown in by the air duct 10 is diffused in the circulation channel 12 and then enters the cracking chamber 6 through the uniform air holes, and the above structure can make the air entering the cracking chamber 6 uniform and soft, thereby improving the reaction efficiency. As a further structure, a partition plate 13 is provided between the shell 11 and the furnace body 1, so as to separate the space between the shell 11 and the furnace body 1 into a heat insulation cavity 14 and the circulation channel 12, so that the shell 11 and the furnace body 1 form a double-layer structure, and the shell 11 can prevent the high-temperature furnace body 1 from being exposed and causing danger.

[0037] As shown in the figure, the bottom of the furnace body 1 is a cone with a large upper opening and a small lower opening, the mesh plate 5 is located at the lower opening, and the bottom of the shell 11 is correspondingly a cone with a large upper opening and a small lower opening. The structure of the cone makes it easy for the waste entering the cracking chamber 6 from the feed pipe 3 to be concentrated at the bottom, and can easily leak into the ash storage chamber 7 after combustion.

[0038] As shown in the figure, a groove 15 is provided on the top of the furnace body 1, and a furnace tube 16 communicating with the cracking chamber 6 is provided in the groove 15. The furnace mouth is the pipe mouth of the furnace tube 16. A baffle is provided on the furnace cover 8. There is water in the groove 15, so that the gap between the furnace cover 8 and the furnace tube 16 is flooded to achieve water sealing. If an ordinary sealing ring is used, it will age and fail in a high temperature and high heat environment.

[0039] As shown in the figure, the feed hopper also includes a hopper body 17 communicated with the feed pipe 3, and a push plate 18 is provided in the feed pipe 3. The push plate 18 is connected to the push cylinder through a connecting frame 19, so as to push the waste material falling from the hopper body 17 into the feed pipe 3 into the cracking chamber 6. In the above structure, in order to ensure the stable movement of the push plate 18, a push tube slidingly matched with it is provided in the feed pipe 3, and the push plate 18 is an end plate at the end of the push tube, and the connecting frame 19 is connected to the push tube. There is also a support shell 20 on the outside of the feed hopper, and the push cylinder is installed on the support shell 20. When the waste material falls into the feed pipe 3 through the hopper body 17, it can be pushed into the cracking chamber 6 through the push plate 18.

[0040] As shown in the figure, the relevant structure of the sealing plate 4 is that the feed pipeline 3 includes a pipeline 1 21 and a pipeline 22, the pipeline 1 21 is connected to the cracking chamber 6, the bucket 17 is connected to the pipeline 22, the sealing plate 4 is located between the pipeline 1 21 and the pipeline 22 and can be sealed and contacted with both the pipeline 1 21 and the pipeline 2 22, the sealing plate 4 is moved by the hydraulic cylinder 23, and the hydraulic cylinder 23 can be fixed on the ground or the furnace body 1 by a bracket. In order to ensure sufficient contact between the sealing plate 4 and the pipeline 1 21 and the pipeline 2 22, the corresponding ends of the pipeline 1 21 and the pipeline 2 22 have flange structures.

[0041] As shown in the figure, an opening is provided on one side of the ash storage chamber 7, and an ash storage drawer 24 which can be pulled out from the opening is provided in the ash storage chamber 7. The above structure is convenient for workers to clean up waste residues.

[0042] like Figure 4 and 6 As shown, the oil barrel heating device includes a main oil barrel 25 for containing oil, the main oil barrel 25 is a conventional cylindrical shape, and also includes a heating bin 26 and a combustion chamber 27 located below the heating bin 26. The application is a vertical structure as a whole, the combustion chamber 27 is located below the main oil barrel 25, the main oil barrel 25, the heating bin 26 and the combustion chamber 27 are arranged in sequence from top to bottom, and a plurality of gas channels 28 communicating with the combustion chamber 27 are provided in the heating bin 26, the inner cavity of the heating bin 26 is sealed, the gas channels 28 are arranged in parallel and pass through the upper and lower surfaces of the entire heating bin, and the gas channels 28 are connected to the outside world, so that the oil located in the heating bin can fill the gas channels 28 and fully contact with the gas channels 28, the heating bin 26 is connected to the main pump 29 through an oil pipe 1, the heating bin 26 is connected to the main oil barrel 25 through an oil pipe 2, the cracking chamber is connected to the combustion chamber 27 through a gas pipeline, and the combustion chamber 27 is connected to the outside world through an air pipe 30. The gas source of the present application is the combustible gas produced by the garbage cracking gasification furnace, which is not only environmentally friendly but also low in cost. Through the above structure, the combustible gas is mixed with air in the combustion chamber 27 and then burned, thereby heating the hot oil in the heating bin 26, and the gas also heats the hot oil in the heating bin 26 while flowing through the gas channel 28, so that the heating efficiency is high. The heated hot oil is pumped into the mold through the main pump 29 to heat the mold and then returns to the main oil barrel 25, thereby forming a cycle.

[0043] As shown in the figure, it also includes a barrel shell 31 arranged outside the main oil barrel 25, and an annular flue 32 is formed between the main oil barrel 25 and the barrel shell 31. The gas channel 28 is connected to the flue 32. There is an interlayer chamber 33 between the bottom surface of the main oil barrel 25 and the top surface of the heating chamber 26. The edge of the interlayer chamber 33 is connected to the flue 32. One end of the gas channel 28 is connected to the interlayer chamber 33. The gas in the interlayer chamber 33 can also heat the main oil barrel 25, and the interlayer chamber 33 can buffer the gas, so that the gas flows out of the flue 32 slowly and evenly, so as to exchange heat to the oil in the main oil barrel 25 as much as possible. The flue 32 is connected to the outside world, so that before the gas in the gas channel 28 is discharged, the waste heat of the gas can also be used to heat the cold oil in the main oil barrel 25, so that the oil in the main oil barrel 25 is preheated before entering the heating chamber 26, which not only makes full use of the heat but also shortens the heating time in the heating chamber 26. As a further structure, it also includes an outer shell body 34 arranged outside the barrel shell body 31, and an annular oil chamber 35 is formed between the outer shell body 34 and the barrel shell body 31. The oil chamber 35 is connected with the main oil barrel 25 through a pipeline. The above structure forms a sandwich layer for the flue 32, so that the inner wall and the outer wall of the flue 32 are not in contact with the outside world, and the heat thereof will be absorbed by the oil in the main oil barrel 25 and the oil in the oil chamber 35, thereby improving the utilization efficiency of thermal energy. The oil after cooling in the mold first flows through the oil chamber 35 and then enters the main oil barrel 25, which further increases the preheating time of the oil.

[0044] As shown in the figure, the end of the barrel shell 31 is a cone 36, and a smoke exhaust pipe is provided at the end of the cone 36. The smoke in the flue 32 can be guided through the cone 36 and discharged through the smoke exhaust pipe.

[0045] As shown in the figure, a partition 37 is provided inside the combustion chamber 27 so as to divide the combustion chamber 27 into an upper chamber 38 and a lower chamber 39. The partition 37 is provided with uniform air holes. After the gas entering the gas pipeline 9 and the air entering the air pipe 30 are mixed in the lower chamber 39, uniform combustion is formed through the uniform air holes. Such a structure ensures that the gas and air have sufficient mixing time and can be fully and uniformly burned. As a further structure, a heat insulation board 40 is provided outside the upper chamber 38, which can not only prevent heat loss, but also prevent burns caused by accidental contact with the combustion chamber 27, and an annular sealing plate 41 is provided outside the lower chamber 39. An annular air cavity is formed between the lower chamber 39 and the sealing plate 41. The air pipe 30 is connected to the air cavity, and a plurality of air holes are provided on the wall of the lower chamber 39. In this way, after the air enters the air cavity, it can enter the lower chamber 39 from the air holes, so as to mix with the gas entering the lower chamber 39 from multiple points, thereby achieving uniform mixing, and the air holes can make the air uniform and soft.

[0046] like Figure 7 and 8As shown, the temperature regulating oil distribution device includes an oil distribution pipe, a main circulation oil circuit and a branch circulation oil circuit. The main circulation oil circuit includes a main pump 29, a main oil barrel 25, a main oil supply pipe 46 and a main oil return pipe 47. One end of the main oil return pipe 47 is connected to the main oil supply pipe 46 and the other end of the main oil return pipe 47 is connected to the main oil barrel 25. The main pump 29 is connected to the main oil barrel 25 through the main oil supply pipe 46 and the main oil return pipe 47 to form a main circulation. The branch circulation oil circuit includes a plurality of branch pumps 42, a plurality of branch oil barrels 43, a plurality of branch oil supply pipes 48, a plurality of branch oil return pipes 50, and the branch pumps 42 is also connected to the corresponding mold and branch oil barrel 43 through pipelines so that the branch pump 42 can supply the oil in the branch oil barrel 43 to the mold for heating. The branch return oil pipe 50 is connected to the main oil barrel 25 and the corresponding mold so that the cooled oil can flow back to the main oil barrel 25 for reheating. The main oil supply pipe 46 is connected to the branch oil supply pipe 48 through the oil distribution pipe, so as to transport the heated oil to the branch oil barrel 43. Valves are provided on the main return oil pipe 47, the branch oil supply pipe 48 and the branch return oil pipe 50. The valves are ordinary solenoid valves or ordinary water valves.

[0047] Because the present application directly burns and heats the oil in the heating bin by burning the combustible gas in the combustion chamber, and then the heating bin is connected to the main pump 29 through a pipeline to provide hot oil. Of course, the other end of the heating bin is connected to the main oil barrel 25. The combustion chamber and the heating bin are designed with existing oil technology and are not the improvement point of the present application. Therefore, the specific structure is not described in detail. The heated oil then enters the branch oil barrel 43 through the oil distribution pipe and the branch oil supply pipe 48. The above structure can realize dynamic heating of the oil, thereby realizing rapid heating and can be burned and used immediately. However, the above heating method is difficult to achieve oil temperature regulation. The oil temperature after combustion and heating is relatively high, so it cannot be directly supplied to the mold for use, and can only be adjusted through the branch oil barrel 43 for use.

[0048] As a preferred structure, it also includes a second branch return oil pipe 49, which is connected to the corresponding mold and the branch oil barrel 43. The branch return oil pipe 49 is also provided with a valve. Through the above structure, a closed loop can be formed between the branch oil barrel 43 of the present application and the mold. Because the temperature required by the mold is within a range of values, if the oil temperature in the branch oil barrel 43 is within the corresponding range, there is no need to supply oil through the main oil supply pipe 46 to increase the temperature, and self-circulation heating is sufficient. In this way, the main circulation oil circuit can stop heating, thereby avoiding waste.

[0049] As shown in the figure, it also includes a square box body 44. The main body of the box body 44 is welded with steel and steel plates. A partition plate 45 is provided in the box body 44. The support oil barrels 43 are arranged on the partition plate 45. The support pumps 42 are installed on the bottom plate of the box body 44. The support oil barrels 43 of the present application have eight arranged in two rows in parallel on the partition plate 45, and the support pumps 42 also have eight arranged in two rows in parallel on the bottom plate. In order to avoid the temperature of the support pumps 42 being too high, a cooling fan is provided on the side panel of the box body 44.

[0050] The principle of the present application is that when the mold starts working, the valve on the main oil return pipe 47 is in a closed state, and the combustion of the combustible gas in the combustion chamber directly burns and heats the oil in the heating bin. The oil in the main oil supply pipe 46 is pumped into the oil branch pipe through the main pump 29. The oil branch pipe is actually a multi-way pipe. Because the present application has eight branch oil barrels 43, the oil branch pipe has eight outlets and one inlet. The oil branch pipe introduces the oil into the corresponding branch oil barrels 43 respectively. After the branch oil barrels 43 are full, the valve on the branch oil supply pipe 48 is closed, and the oil can be naturally cooled and temperature adjusted. The valve on the main oil return pipe 47 is opened, the main circulation oil circuit is opened, and the oil in the main oil barrel 25 is circulated and heated through the main oil supply pipe 46 and the main return oil pipe 47; when the oil in the branch oil barrel 43 reaches the required temperature, the valve on the branch return oil pipe 2 49 is opened, the valve on the branch return oil pipe 1 50 is closed, and the branch pump 42 starts working Thereby realizing the internal circulation mode of the oil in the branch oil barrel 43 from the branch oil barrel 43 to the mold until the temperature of the oil is lower than the lower limit of the temperature required by the mold. At this time, the valves on the main return oil pipe 47 and the branch return oil pipe 2 49 are closed, and the valves on the branch oil supply pipe 48 and the valves on the branch return oil pipe 1 50 are opened. The main oil supply pipe 46 pumps the burned and heated oil into the oil distribution pipe and the branch oil barrel 43 through the main pump 29. The branch pump 42 will transport the oil in the branch oil barrel 43 to the mold and then return it to the main oil barrel 25 through the branch return oil pipe 1 50. This process is the external circulation mode of the oil, thereby ensuring that the temperature of the oil in the branch oil barrel 43 steadily increases until it reaches the upper limit of the temperature required by the mold, and then the internal circulation mode starts until the oil temperature in the branch oil barrel 43 is lower than the lower limit of the temperature required by the mold, and then the external circulation mode starts, and the above process works repeatedly.

[0051] The above is a detailed introduction to a mold heating and heat supply system provided by an embodiment of the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
