Description

Technical Field

[0001] The utility model relates to the technical field of heat energy reuse of trolley type heating furnaces, in particular to a trolley type heating furnace capable of realizing heat energy reuse. Background Technique

[0002] A trolley type heating furnace is a device used for heating materials, usually used in industrial production. It can process raw materials into required products through heating. A trolley type heating furnace capable of realizing heat energy reuse refers to effectively collecting and utilizing waste heat during the heating process to achieve energy reuse and conservation. This type of heating furnace usually is equipped with a heat recovery system, such as a waste heat boiler or a heat exchanger, for capturing and utilizing the generated waste heat. In this way, the waste heat can be converted into energy or used to heat other materials, thereby reducing energy consumption and production costs.

[0003] The existing patent (Publication No.: CN201233184Y) proposed a heat energy reuse structure for a heating furnace body, and then the hot air discharged from the air outlet channel of a heating furnace body can be guided to the air inlet channel of another heating furnace body for reuse, so that the other heating furnace body uses the inflowing hot air with a certain temperature to assist in heating up; in this way, each heating furnace body with interconnected air inlets and outlets can sequentially guide the discharged hot air to the adjacent interconnected heating furnace body for recycling, so as to save the power consumption of each heating furnace body and achieve the practical benefits of saving energy and cost.

[0004] However, the existing trolley type heating furnaces are usually used for intermittent operation. This periodic heating method results in the ineffective utilization of the heat accumulated in the furnace after each heating cycle, thus causing relatively large heat energy losses. Although a new type of heat exchanger can be used to preheat the combustion air with flue gas waste heat to save energy, the initial investment is relatively large. The complex operation process and highly automated control system may also bring safety risks and require strict operating procedures and safety measures. Therefore, the utility model proposes a trolley type heating furnace capable of realizing heat energy reuse to solve the above problems. Content of the Utility Model

[0008] The beneficial effect of adopting the above further scheme is that: through the arranged water storage tank, the water in the water storage tank can store water for the upper part of the water heating tank.

[0010] The beneficial effect of adopting the above further scheme is that: since a second valve is fixed on the water inlet pipe, by opening the second valve, the second valve can control the water in the water storage tank to flow into the water heating tank. Since a first water pump is fixed on the side of the water inlet pipe close to the second valve, by opening the first water pump, the water in the water storage tank can be pumped into the water heating tank. Since the water inlet pipe is fixed on the water heating tank, the water inlet pipe connects the water storage tank and the water heating tank.

[0012] The beneficial effects of adopting the above further scheme are as follows: Since the first water outlet pipe is fixed to the top of the water heating tank, the hot water in the upper part of the water heating tank can be discharged through the first water outlet pipe. Since the second water pump is fixed to the first water outlet pipe, the second water pump can be turned on to pump out the hot water in the water heating tank. Since the third valve is fixed to the first water outlet pipe, the third valve can control the water extraction in the first water outlet pipe.

[0016] The beneficial effects of adopting the above further scheme are as follows: Due to the limiting groove formed in the fixing block, when the second smoke exhaust pipe is connected to other pipes, the limiting groove can play a limiting role on the pipes. Since the bolt is threadedly connected to the fixing block, the whole connection component can fixedly connect the second smoke exhaust pipe to other pipes.

The smoke flows to the smoke inlet pipe through the second smoke exhaust pipe. Through the cooperation of the smoke inlet groove and the smoke guiding groove provided in the smoke inlet pipe, the smoke can quickly flow from the smoke inlet pipe to the inside of the heating furnace to preheat the inside of the heating furnace. Through the provided heat preservation layer, the heat preservation layer keeps warm the smoke with heat in the smoke inlet pipe to prevent the heat from quickly dissipating, thereby solving the technical problem of realizing heat energy reuse of the trolley-type heating furnace.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1-3As shown in the figure, the first heat energy reuse component 6 includes a first exhaust pipe 61, the first exhaust pipe 61 is fixed on the heating furnace 1, a water heating tank 62 is fixed on the first exhaust pipe 61, the water heating tank 62 is fixed on the base 5, a box door 63 is rotatably connected to the water heating tank 62, a second exhaust pipe 64 is fixed on the side of the water heating tank 62 away from the first exhaust pipe 61, an inlet smoke pipe 65 is fixed on the second exhaust pipe 64, a first valve 66 is fixed on the inlet smoke pipe 65, a smoke inlet groove 67 is provided in the inlet smoke pipe 65, a smoke guiding groove 68 is provided in the inlet smoke pipe 65, and a heat insulation layer 69 is fixed on the inlet smoke pipe 65. In actual operation, the operator will first open the first valve 66, so that the smoke with a large amount of heat generated in the heating furnace 1 will flow to the bottom inside the water heating tank 62 through the first exhaust pipe 61. These smokes then flow to the inlet smoke pipe 65 through the second exhaust pipe 64. Inside the inlet smoke pipe 65, a smoke inlet groove 67 and a smoke guiding groove 68 are provided, and the cooperation of the two can enable the smoke to quickly flow from the inlet smoke pipe 65 to the inside of the heating furnace 1 for preheating the heating furnace 1. In order to retain the heat in the smoke, a heat insulation layer 69 is also provided on the inlet smoke pipe 65, and this heat insulation layer 69 can effectively prevent the heat in the smoke from quickly escaping, thus solving the technical problem of realizing heat energy reuse in the trolley 4 type heating furnace 1.

[0026] In the above solution, there is also a problem that when the heating furnace 1 generates heat, it cannot meet the maximum utilization of heat energy, such as Figure 1 and Figure 4As shown: A second thermal energy reuse component 7 is provided on the base 5. The second thermal energy reuse component 7 includes a water storage tank 71. The water storage tank 71 is fixed on the base 5. A water inlet pipe 72 is fixed on the water storage tank 71. Through the arranged water storage tank 71, the water in the water storage tank 71 can store water for the upper half of the water heating tank 62. Since the water storage tank 71 is fixed on the base 5, the base 5 plays a fixing role for the water storage tank 71. Since the water inlet pipe 72 is fixed on the water storage tank 71, the water in the water storage tank 71 can flow into the water heating tank 62 through the water inlet pipe 72. A second valve 73 is fixed on the water inlet pipe 72. A first water pump 74 is fixed on one side of the water inlet pipe 72 close to the second valve 73. The water inlet pipe 72 is fixed on the water heating tank 62. Since the second valve 73 is fixed on the water inlet pipe 72, by opening the second valve 73, the second valve 73 can control the water in the water storage tank 71 to flow into the water heating tank 62. Since the first water pump 74 is fixed on one side of the water inlet pipe 72 close to the second valve 73, by opening the first water pump 74, the water in the water storage tank 71 can be pumped into the water heating tank 62. Since the water inlet pipe 72 is fixed on the water heating tank 62, the water inlet pipe 72 connects the water storage tank 71 and the water heating tank 62. A first water outlet pipe 75 is fixed on the top of the water heating tank 62. A second water pump 76 is fixed on the first water outlet pipe 75. A third valve 77 is fixed on the first water outlet pipe 75. The other end of the first water outlet pipe 75 is fixed on a heat preservation tank 78. The heat preservation tank 78 is fixed on the base 5. A second water outlet pipe 79 is fixed on the heat preservation tank 78. Since the first water outlet pipe 75 is fixed on the top of the water heating tank 62, the hot water in the upper half of the water heating tank 62 can be discharged through the first water outlet pipe 75. Since the second water pump 76 is fixed on the first water outlet pipe 75, by opening the second water pump 76, the hot water in the water heating tank 62 can be pumped out. Since the third valve 77 is fixed on the first water outlet pipe 75, the third valve 77 can control the water extraction in the first water outlet pipe 75. Through the arranged heat preservation tank 78, the heat preservation tank 78 can store and keep warm the hot water extracted from the water heating tank 62. Since the heat preservation tank 78 is fixed on the base 5, the base 5 can play a role in supporting and fixing the heat preservation tank 78. Since the second water outlet pipe 79 is fixed on the heat preservation tank 78, the second water outlet pipe 79 can discharge the water in the heat preservation tank 78.

[0027] As Figures 1-2As shown in the figure, a connection component 8 is provided on the second exhaust pipe 64. The connection component 8 includes a rotating shaft 81, and a fixing block 82 is fixed on the rotating shaft 81. Through the cooperation of the provided rotating shaft 81 and the fixing block 82, the fixing block 82 can rotate on the rotating shaft 81. The fixing block 82 is fixed on the second exhaust pipe 64, and a limiting groove 83 is formed in the fixing block 82. A bolt 84 is threadedly connected to the fixing block 82. Due to the limiting groove 83 formed in the fixing block 82, when the second exhaust pipe 64 is connected to other pipes, the limiting groove 83 can play a limiting role on the pipes. Due to the bolt 84 being threadedly connected to the fixing block 82, the whole connection component 8 can fixedly connect the second exhaust pipe 64 to other pipes.

[0028] Working principle: As Figures 1-4 shown in the figure, first, the operator opens the first valve 66. In this way, the smoke with a large amount of heat generated in the heating furnace 1 will flow through the first exhaust pipe 61 to the bottom inside the water heating tank 62. These smokes then flow through the second exhaust pipe 64 into the smoke inlet pipe 65. Inside the smoke inlet pipe 65, a smoke inlet groove 67 and a smoke guiding groove 68 are provided. The cooperation of the two can enable the smoke to quickly flow from the smoke inlet pipe 65 into the inside of the heating furnace 1 for preheating the heating furnace 1. In order to retain the heat in the smoke, a heat insulation layer 69 is also provided on the smoke inlet pipe 65. This heat insulation layer 69 can effectively prevent the heat in the smoke from quickly escaping. During operation, first, the second valve 73 is opened. As the control switch of the water flow, the opening of this valve enables the water in the water storage tank 71 to flow through the water inlet pipe 72 into the water heating tank 62. In order to accelerate the water flow rate or when the height difference between the water storage tank 71 and the water heating tank 62 is not sufficient to drive the water flow, a first water pump 74 can be installed at a position on the water inlet pipe 72 close to the second valve 73. When the first water pump 74 is started, it pumps the water in the water storage tank 71 into the water heating tank 62, ensuring the continuity and stability of the water flow. In order to ensure the stability and safety of the connection between the second exhaust pipe 64 in the exhaust system and other pipes, a limiting groove 83 is formed inside the fixing block 82. This design enables the limiting groove 83 to effectively limit and guide the position of the second exhaust pipe 64 during the connection process. This not only helps to ensure the precise docking of the pipes during installation but also greatly improves the stability and reliability of the entire exhaust system.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
