Description

Technical Field

[0001] The utility model relates to the technical field of the furnace chamber of an in-line furnace, in particular to the structure of the furnace chamber of an in-line furnace. Background Art

[0002] An in-line furnace is a kind of non-ferrous metal casting equipment. In-line furnaces are usually used for casting ingots, rods, tubes, plates, alloy castings, etc. When operating, an in-line furnace needs to be connected to an external smelting furnace, and the required casting materials are provided through the smelting of the materials in this furnace. The in-line furnace has an independent control ability, can complete the casting process independently, and can be equipped with an independent automated casting system to improve casting efficiency and production quality.

[0003] At present, as the main space for fuel combustion in an in-line furnace, the furnace chamber of the in-line furnace ensures that the fuel burns as much as possible and cools the flue gas temperature at the furnace chamber outlet to the temperature allowed for the safe operation of the convective heating surface, so as to ensure the full combustion of the fuel and the effective cooling of the flue gas. However, during the process of the inner wall of the furnace chamber being baked at high temperature, the temperature outside the furnace chamber will be very high. The natural cooling method will cause the furnace chamber temperature and the flue gas temperature at the furnace chamber outlet to decrease relatively slowly. The continuous high temperature of the furnace chamber will reduce its service life, and the too high flue gas at the furnace chamber outlet will also affect the environmental ecological balance. Therefore, we propose the structure of the furnace chamber of the in-line furnace to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the above background art and propose the structure of the furnace chamber of an in-line furnace.

[0006] The structure of the furnace chamber of an in-line furnace includes the furnace chamber body of the in-line furnace, a melting crucible, and a gas heating device arranged at the bottom inside the furnace chamber body of the in-line furnace. An annular groove and a plurality of exhaust holes are respectively opened at the top of the outer side wall and the outer side wall of the furnace chamber body of the in-line furnace. A fitting snap ring block that slides with the inner wall of the annular groove is fixedly connected to the outer side wall of the melting crucible. A plurality of exhaust pipes communicated with the exhaust holes are fixedly connected to the outer side wall of the furnace chamber body of the in-line furnace. A heat absorption box fixedly connected to the outer wall of the furnace chamber body of the in-line furnace is fixedly connected to the outer side wall of the exhaust pipe. An open cooling pipe communicated with the heat absorption box is fixedly connected to the outer side wall of the furnace chamber body of the in-line furnace. A central pipe joint communicated with a plurality of open cooling pipes is fixedly connected to the bottom of the furnace chamber body of the in-line furnace. A drain pipe and a water inlet pipe are respectively fixedly connected to the top of the heat absorption box and the outer side wall of the central pipe joint.

[0007] Preferably, two support frames are fixedly connected to the bottom of the furnace chamber body of the in-line furnace.

[0008] Preferably, a communication hole communicating with the open cooling pipe is formed in the outer side wall of the heat absorption box.

[0009] Preferably, a plurality of the exhaust pipes and a plurality of the open cooling pipes are both annularly arrayed on the outer side wall of the furnace body of the side furnace.

[0010] Preferably, fixing holes are formed in the outer side wall of the heat absorption box, and the outer side wall of the exhaust pipe on the same side is fixedly connected with the inner side wall of the fixing hole.

[0011] The beneficial effects of the present utility model are as follows:

[0012] Under the interaction of the furnace body of the side furnace, the melting crucible, the annular groove, the exhaust hole, the exhaust pipe, the heat absorption box, the open cooling pipe and the centralized pipe joint, by injecting cooling water into the water inlet pipe and allowing it to flow through the centralized pipe joint, the open cooling branch pipe and the heat absorption box in sequence and finally discharging from the drain pipe, the cooling water can reduce the temperature of the furnace body of the side furnace in the open cooling pipe, and at the same time, the cooling water can reduce the temperature of the combustion flue gas passing through the exhaust pipe in the heat absorption box, which not only prolongs the service life of the furnace body of the side furnace, but also can reduce the temperature of the combustion flue gas and avoid affecting the environment.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Refer to Figures 1-4, The structure of the furnace chamber of the side-mounted furnace includes the furnace chamber body 1 of the side-mounted furnace, the melting crucible 2, and the gas heating device 3 arranged at the inner bottom of the furnace chamber body 1 of the side-mounted furnace. An annular groove 4 and a plurality of exhaust holes 5 are respectively opened at the top and the outer side wall of the outer side wall of the furnace chamber body 1 of the side-mounted furnace. A fitting clamping ring block 6 that slides with the inner wall of the annular groove 4 is fixedly connected to the outer side wall of the melting crucible 2. Two support frames 13 are fixedly connected to the bottom of the furnace chamber body 1 of the side-mounted furnace. The gas heating device 3 can heat the bottom of the melting crucible 2. The gas heating device 3 is a common means in the prior art and will not be elaborated here.

[0020] A plurality of exhaust pipes 7 communicated with the exhaust holes 5 are fixedly connected to the outer side wall of the furnace chamber body 1 of the side-mounted furnace. A heat absorption box 8 fixedly connected to the outer wall of the furnace chamber body 1 of the side-mounted furnace is fixedly connected to the outer side wall of the exhaust pipe 7. A fixing hole is opened on the outer side wall of the heat absorption box 8, and the outer side wall of the exhaust pipe 7 on the same side is fixedly connected to the inner side wall of the fixing hole.

[0021] An open cooling pipe 9 communicated with the heat absorption box 8 is fixedly connected to the outer side wall of the furnace chamber body 1 of the side-mounted furnace. The plurality of exhaust pipes 7 and the plurality of open cooling pipes 9 are both arranged in an annular array on the outer side wall of the furnace chamber body 1 of the side-mounted furnace. A communication hole communicated with the open cooling pipe 9 is opened on the outer side wall of the heat absorption box 8.

[0022] A centralized pipe joint 10 communicated with the plurality of open cooling pipes 9 is fixedly connected to the bottom of the furnace chamber body 1 of the side-mounted furnace. A drain pipe 11 and a water inlet pipe 12 are respectively fixedly connected to the top of the heat absorption box 8 and the outer side wall of the centralized pipe joint 10. The end of the water inlet pipe 12 is connected to a water pump immersed in cooling water, which is convenient for the water pump to input cooling water into the water inlet pipe 12. The water pump is not Figure 1 shown in the figure. This is a common means in the prior art and will not be elaborated here.

[0023] The function principle of the present utility model can be described by the following operation method: When using the melting crucible 2 in the furnace chamber body 1 of the side-mounted furnace to melt materials, the gas heating device 3 can heat the bottom of the melting crucible 2, so as to melt the materials in the melting crucible 2. During the melting process of the melting crucible 2, the heat generated after the combustion of the gas heating device 3 will radiate to the inner wall of the furnace chamber body 1 of the side-mounted furnace, making the outer wall of the furnace chamber body 1 of the side-mounted furnace hot. At the same time, the high-temperature exhaust gas after combustion will enter the exhaust pipe 7 from the exhaust hole 5 and be discharged.

[0024] By injecting cooling water into the water inlet pipe 12, the cooling water will enter the centralized pipe joint 10. The cooling water enters the open-type cooling pipe 9 through the centralized pipe joint 10. When the cooling water contacts the high-temperature outer wall of the furnace body 1 of the side-mounted furnace, the cooling water absorbs the heat from the outer wall of the furnace body 1 of the side-mounted furnace, thereby reducing the temperature of the furnace body 1 of the side-mounted furnace. As the cooling water rises in the open-type cooling pipe 9 until it rises into the heat absorption box 8, the cooling water in the heat absorption box 8 can cool the exhaust pipe 7, thereby reducing the temperature of the exhaust gas discharged from the exhaust pipe 7. Until the cooling water rises in the heat absorption box 8 until it is discharged from the drain pipe 11, the flow of the cooling water can reduce the temperature of the furnace body 1 of the side-mounted furnace. Until when the melting crucible 2 is not melting materials, when the temperature of the furnace body 1 of the side-mounted furnace drops to normal temperature, stop injecting cooling water into the water inlet pipe 12.

[0025] As mentioned above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
