Description

Technical Field

[0001] The utility model belongs to the technical field of heating furnaces, and in particular relates to an automatic heating furnace capable of reducing heat loss. Background Art

[0002] A heating furnace is a device (industrial furnace) that heats materials or workpieces (usually metals) to the rolling and forging temperature. Heating furnaces include continuous heating furnaces and chamber heating furnaces. Heating furnaces used for metal heat treatment are also called heat treatment furnaces. Furnaces that heat steel ingots before initial rolling or make the internal temperature of the steel ingots uniform are called soaking furnaces. In a broad sense, heating furnaces also include soaking furnaces and heat treatment furnaces. Heating furnaces are used in many industries such as petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharmaceuticals.

[0003] The existing heating furnace burns the fuel in the combustion chamber during operation. During the combustion of the fuel, a large amount of heat is generated, which heats the heating furnace, thereby increasing the temperature inside the heating furnace. During the heating process, since the inlet and outlet of the furnace body are movably connected to the furnace door through hinges, there will be a gap between the furnace door and the furnace body, and heat can easily overflow from the gap. When the heat is lost quickly and the temperature inside the furnace body does not meet the standard, the efficiency of heating the components is reduced. Therefore, we provide an automatic heating furnace that can reduce heat loss. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic heating furnace which can reduce heat loss, and solve the problems raised in the above-mentioned background technology by using a heat preservation pad, a double-axis motor, a threaded rod, a threaded sleeve, a connecting column, a connecting plate, a sealing plate and a sealing ring in combination.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic heating furnace capable of reducing heat loss, comprising a furnace body, the surface of the furnace body being wrapped with a heat preservation pad, the top of the furnace body being fixedly connected to a shell, a dual-axis motor being fixedly installed at the bottom of the inner cavity of the shell, the output ends on both sides of the dual-axis motor being fixedly connected to threaded rods, the surface of the threaded rods being threadedly connected to threaded sleeves, the top of the threaded sleeves being fixedly connected to a connecting column, one end of the connecting column being fixedly connected to a connecting plate, one side of the connecting plate being fixedly connected to a sealing plate, and a sealing ring being sleeved on the sealing plate.

[0006] By adopting the above scheme, the threaded rod is driven to rotate by a dual-axis motor. Since the directions of the threads on the two threaded rods are opposite, when the dual-axis motor drives the two threaded rods to rotate forward or reverse, the threaded rod can drive the two threaded sleeves to move toward or in the opposite direction. When the threaded rod rotates forward, the threaded rod drives the two threaded sleeves to move inward, the threaded sleeve drives the connecting column to move, the connecting column drives the connecting plate to move, and the connecting plate drives the sealing plate to move until the two sealing plates are respectively clamped with the inlet and outlet of the furnace body. When the clamping is completed, a closed space is formed inside the furnace body. At the same time, because a sealing ring is provided on the surface of the sealing plate, the sealing effect of the furnace body is further improved to prevent heat loss.

[0007] As a preferred embodiment of an automatic heating furnace that can reduce heat loss, a combustion chamber is fixedly connected to the bottom of the furnace body, a blower is fixedly installed on the back of the combustion chamber, and the blower and the combustion chamber are connected by a pipeline.

[0008] By adopting the above scheme, the airflow is delivered to the combustion chamber by the blower in cooperation with the pipeline, thereby accelerating the combustion speed of the fuel and making it burn more completely.

[0009] As a preferred embodiment of an automatic heating furnace capable of reducing heat loss, a bearing is sleeved on one end of the threaded rod, and one side of the bearing is fixedly connected to one side of the inner cavity of the shell.

[0010] By adopting the above solution and setting the bearing, the wear on one end of the threaded rod is reduced, and the smoothness of the threaded rod when rotating is greatly improved.

[0011] As a preferred embodiment of an automatic heating furnace capable of reducing heat loss, a heat dissipation port is provided on the back of the shell, and a dustproof net is provided in the inner cavity of the heat dissipation port.

[0012] By adopting the above solution, the dust outside is shielded by the provision of a dustproof net to prevent dust from entering the inner cavity of the shell and causing the dual-axis motor to jam during operation.

[0013] As a preferred embodiment of an automatic heating furnace that can reduce heat loss, guide grooves are provided on both sides of the bottom of the shell cavity, a guide block is fixedly connected to the bottom of the threaded sleeve, and the bottom of the guide block is slidably connected to the inner wall of the guide groove.

[0014] By adopting the above scheme, the guide block is limited by setting the guide groove, and the threaded sleeve is assisted to move horizontally to prevent the threaded sleeve from rotating.

[0015] As a preferred embodiment of an automatic heating furnace capable of reducing heat loss, a base plate is fixedly connected to the bottom of the combustion chamber, and a door is movably connected to the surface of the combustion chamber via a hinge.

[0016] By adopting the above solution, the base plate is provided to prevent the combustion chamber from directly contacting the ground, and when the ground is damp, the bottom of the combustion chamber cannot be corroded.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model drives the threaded rod to rotate through a double-axis motor. Since the threads on the two threaded rods are in opposite directions, when the double-axis motor drives the two threaded rods to rotate forward or reverse, the threaded rods can drive the two threaded sleeves to move toward or in the opposite direction. When the threaded rods rotate forward, the threaded rods drive the two threaded sleeves to move inward, the threaded sleeves drive the connecting column to move, the connecting column drives the connecting plate to move, and the connecting plate drives the sealing plate to move until the two sealing plates are respectively clamped with the inlet and outlet of the furnace body. When the clamping is completed, a closed space is formed inside the furnace body. At the same time, because the surface of the sealing plate is provided with a sealing ring, the sealing effect of the furnace body is further improved to prevent heat loss.

[0019] 2. The utility model delivers airflow to the combustion chamber through the blower in cooperation with the pipeline, accelerates the combustion speed of the fuel, and makes it burn more completely, greatly improving the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figure 1-3 , an automatic heating furnace capable of reducing heat loss, comprising a furnace body 1, see Figure 2 As shown, the bottom of the furnace body 1 is fixedly connected to a combustion chamber 11, and a blower 12 is fixedly installed on the back of the combustion chamber 11. The blower 12 and the combustion chamber 11 are connected through a pipeline 13. The blower 12 conveys airflow to the combustion chamber 11 in cooperation with the pipeline 13 to accelerate the combustion speed of the fuel and make it burn more fully. The surface of the furnace body 1 is wrapped with a heat preservation pad 2, and the top of the furnace body 1 is fixedly connected to a shell 3. Figure 3 As shown, guide grooves are provided on both sides of the bottom of the inner cavity of the shell 3, and a guide block is fixedly connected to the bottom of the threaded sleeve 6, and the bottom of the guide block is slidably connected to the inner wall of the guide groove. The guide groove is set to limit the guide block to assist the threaded sleeve 6 to move laterally to prevent the threaded sleeve 6 from rotating. A dual-axis motor 4 is fixedly installed at the bottom of the inner cavity of the shell 3, and threaded rods 5 are fixedly connected to the output ends on both sides of the dual-axis motor 4. The surface of the threaded rod 5 is threadedly connected to the threaded sleeve 6, and the top of the threaded sleeve 6 is fixedly connected to a connecting column 7, one end of the connecting column 7 is fixedly connected to a connecting plate 8, and one side of the connecting plate 8 is fixedly connected to a sealing plate 9, and a sealing ring 10 is sleeved on the sealing plate 9, and the threaded rod 5 is driven to rotate by the dual-axis motor 4. Because the directions of the threads on the two threaded rods 5 are opposite, when the dual-axis motor 4 drives the two threaded rods 5 to rotate forward or reverse, the threaded rods 5 can drive the two threaded sleeves 6 to move toward or in the opposite direction. When the threaded rods 5 rotate forward, the threaded rods 5 drive the two threaded sleeves 6 to move inward, and the threaded sleeves 6 drive the connecting column 7 to move, and the connecting column 7 drives the connecting plate 8 to move, and the connecting plate 8 drives the sealing plate 9 to move until the two sealing plates 9 are respectively connected to the inlet and outlet of the furnace body 1. When the connection is completed, a closed space is formed inside the furnace body 1. At the same time, because the surface of the sealing plate 9 is provided with a sealing ring 10, the sealing effect of the furnace body 1 is further improved to prevent heat loss.

[0025] See Figure 3 As shown, one end of the threaded rod 5 is sleeved with a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the housing 3. By setting the bearing, the wear on one end of the threaded rod 5 is reduced, and the smoothness of the threaded rod 5 when rotating is greatly improved. Figure 3 As shown, a heat dissipation port is provided on the back of the housing 3, and a dustproof net is provided in the inner cavity of the heat dissipation port. The dustproof net is provided to block external dust and prevent dust from entering the inner cavity of the housing 3, which may cause the dual-axis motor 4 to jam during operation. Figure 1 As shown, the bottom of the combustion chamber 11 is fixedly connected to a base plate, and the surface of the combustion chamber 11 is movably connected to a door via hinges. The base plate is provided to prevent the combustion chamber 11 from directly contacting the ground, so that when the ground becomes damp, the bottom of the combustion chamber 11 cannot be corroded.

[0026] When in use, the parts to be heated are first transported to the inner cavity of the furnace body 1 through the inlet on the left side of the furnace body 1. After the feeding is completed, the double-axis motor 4 drives the threaded rod 5 to rotate. Because the threads on the two threaded rods 5 are in opposite directions, when the double-axis motor 4 drives the two threaded rods 5 to rotate forward or reverse, the threaded rod 5 can drive the two threaded sleeves 6 to move toward or in the opposite direction. When the threaded rod 5 rotates forward, the threaded rod 5 drives the two threaded sleeves 6 to move inward, drives the connecting column 7 to move, drives the connecting plate 8 to move through the connecting column 7, and drives the sealing plate 9 through the connecting plate 8. Move until the two sealing plates 9 are respectively engaged with the inlet and outlet of the furnace body 1. When the engagement is completed, a closed space is formed inside the furnace body 1. At the same time, since a sealing ring 10 is provided on the surface of the sealing plate 9, the sealing effect of the furnace body 1 is further improved. Then the fuel is transported to the inner cavity of the combustion chamber 11 and ignited by an external ignition mechanism, so as to heat the furnace body 1. At the same time, during the combustion of the fuel, the blower 12 is started, and the airflow is transported to the combustion chamber 11 through the blower 12 with the cooperation of the pipeline 13, so as to accelerate the combustion speed of the fuel and make it burn more fully, thereby greatly improving the processing efficiency.
