Description

Technical Field

[0001] This utility model relates to the field of melting and holding furnace technology, and in particular to an explosion-proof combustion device for melting and holding furnace. Background Technology

[0002] A melting and holding furnace is a mechanical device used for metal smelting and heat preservation, mainly for melting, heat preservation, and refining of metals such as aluminum alloys. Its core components include the furnace body, molten pool, sealing cover, and riser pipe. It is often used as a key component of low-pressure casting machines. The explosion-proof combustion device of the melting and holding furnace is mainly used to prevent the risk of explosion caused by gas leakage or uncontrolled combustion under high temperature and high pressure environment, and ensures stable operation of the equipment through multiple safety mechanisms.

[0003] Existing technologies, such as CN209655809U, describe a continuous melting and holding furnace at the machine side. The furnace has a base, on which a melting chamber and a discharging chamber are mounted. A melting burner is located on one side of the melting chamber, which contains a melting cavity. A feeding port is located at the top of the melting cavity and is sealed by a furnace cover. A storage cavity is located within the discharging chamber. A holding chamber is located between the melting and discharging chambers, containing a holding cavity with a holding burner at its top. The holding cavity connects the melting chamber and the storage cavity. A heating device is located at the discharging port, with its end positioned within the storage cavity. This continuous melting and holding furnace at the machine side eliminates uneven aluminum molten metal temperatures at the discharging port, improving molten metal quality. The heating element allows for molten metal insulation during holidays, saving energy and reducing carbon dioxide emissions. The holding burner provides temperature protection for the molten metal in case of heating element malfunction, preventing losses.

[0004] To address the issue of explosion-proofing existing insulation furnaces, which tend to experience excessively high internal temperatures and pressures after prolonged use, and which can cause molten material to splatter during extended insulation and heating processes, potentially leading to fires, burns, or even furnace explosions, the existing furnaces are also wasteful of materials and shorten the equipment's lifespan. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing heat preservation furnaces, which, after prolonged use, lead to excessively high internal temperatures and pressures. During long-term heat preservation and heating, this can cause hot molten material to splash, resulting in fires or burns to personnel, and in severe cases, even furnace explosions. Furthermore, these furnaces are material-intensive and shorten the lifespan of the equipment. Therefore, this utility model proposes an explosion-proof combustion device for melting heat preservation furnaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an explosion-proof combustion device for a melting and holding furnace, comprising a furnace body, a support base, and an auxiliary device. The support base is fixedly connected to the lower surface of the furnace body. The furnace body has a slot, which is formed on the surface of the furnace body. An auxiliary device is provided on the inner wall of the slot. The auxiliary device includes a sealing slide plate, which is disposed on the inner wall of the slot. A limiting groove is formed on the inner wall of the slot, and the sealing slide plate is slidably connected to the inner wall of the limiting groove.

[0007] Furthermore, the number of the support bases is two sets and they are symmetrically arranged, the number of the limiting slide grooves is two sets and they are symmetrically arranged, the upper surface of the sealing slide plate is fixedly connected to the limiting slider, and the limiting slider is slidably connected to the inner wall of the groove.

[0008] Furthermore, a connecting plate is fixedly connected to the upper surface of the limiting slider. The connecting plate is located on the outside of the main body of the heat preservation furnace. A fixing plate is fixedly connected to the surface of the main body of the heat preservation furnace. There are two sets of fixing plates.

[0009] Furthermore, a guide rod is fixedly connected to the surface of the fixing plate, and there are two sets of guide rods arranged symmetrically. A tension spring is fixedly connected to the surface of the fixing plate, and the tension spring is sleeved and connected to the surface of the guide rod.

[0010] Furthermore, the end of the tension spring away from the fixed plate is fixedly connected to the surface of the connecting plate. The surface of the connecting plate is provided with guide holes. There are two sets of guide holes arranged symmetrically. The guide rod is sleeved and connected to the inner wall of the guide hole.

[0011] Furthermore, a magnetic suction plate is fixedly connected to the surface of the connecting plate, and a magnetic suction groove is opened on the surface of the fixed plate. The magnetic suction plate is magnetically connected to the inner wall of the magnetic suction groove. A fixing block is fixedly connected to the upper surface of the connecting plate, and the number of fixing blocks is two sets and they are symmetrically arranged.

[0012] Furthermore, a rotating rod is rotatably connected to the inner wall of the fixing block, a torsion spring is fixedly connected to the surface of the fixing block, the torsion spring is sleeved and connected to the surface of the rotating rod, an L-shaped clamping plate is fixedly connected to the end of the torsion spring away from the fixing block, the L-shaped clamping plate is fixedly connected to the surface of the rotating rod, and a handle is fixedly connected to the surface of the L-shaped clamping plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an auxiliary device, the use of the sealing slide plate is more convenient when the main body of the heat preservation furnace is subjected to explosion-proof treatment. When the L-shaped plate is not subjected to external force, the elastic force of the tension spring can push the L-shaped plate to magnetically connect with the fixed plate. When the internal temperature and air pressure of the heat preservation furnace body are too high, the handle is pulled, and the magnetic plate disengages from the magnetic groove, causing the handle to drive the L-shaped plate to rotate along the axis of the rotating rod. Then the torsion spring is deformed by force, and the connecting plate slides stably along the surface of the guide rod, causing the tension spring to be deformed and compressed. Then the connecting plate drives the sealing plate to slide stably along the opening trajectory of the limiting slide groove, so that the groove is in the open state.

[0015] 2. In this utility model, the handle is then released, causing the torsion spring to lose its restraint and rotate the L-shaped clamping plate. Subsequently, the L-shaped clamping plate engages with the surface of the fixing plate, thus fixing the position of the sealing slide plate. By setting an auxiliary device, it is convenient to carry out explosion-proof treatment on the main body of the heat preservation furnace. This avoids the situation where the internal temperature and pressure of the existing heat preservation furnace become too high after prolonged use. During long-term heat preservation and heating, high-temperature molten material splashes, causing fires or burns to personnel. In severe cases, it can lead to the furnace body exploding, which consumes a lot of materials and shortens the life of the equipment. This effectively improves the safety of the equipment.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an explosion-proof combustion device for a melting and heat preservation furnace, including a furnace body 1, a support base 2 and an auxiliary device 3. The support base 2 is fixedly connected to the lower surface of the furnace body 1. The furnace body 1 is provided with a slot 31, which is opened on the surface of the furnace body 1. The auxiliary device 3 is provided on the inner wall of the slot 31.

[0024] The specific setup and function of auxiliary device 3 will be explained below.

[0025] In this embodiment: the auxiliary device 3 includes a sealing slide plate 33, which is disposed on the inner wall of the slot 31. A limiting groove 32 is formed on the inner wall of the slot 31, and the sealing slide plate 33 is slidably connected to the inner wall of the limiting groove 32.

[0026] Specifically, there are two sets of support seats 2 arranged symmetrically, two sets of limiting slide grooves 32 arranged symmetrically, and a limiting slider 34 is fixedly connected to the upper surface of the sealing slide plate 33. The limiting slider 34 is slidably connected to the inner wall of the slot 31.

[0027] Specifically, a connecting plate 35 is fixedly connected to the upper surface of the limiting slider 34. The connecting plate 35 is located on the outside of the heat preservation furnace body 1. A fixing plate 36 is fixedly connected to the surface of the heat preservation furnace body 1. There are two sets of fixing plates 36.

[0028] Specifically, guide rods 37 are fixedly connected to the surface of the fixing plate 36. There are two sets of guide rods 37 arranged symmetrically. Tension springs 38 are fixedly connected to the surface of the fixing plate 36. Tension springs 38 are sleeved and connected to the surface of guide rods 37.

[0029] Specifically, the end of the tension spring 38 away from the fixed plate 36 is fixedly connected to the surface of the connecting plate 35. The surface of the connecting plate 35 is provided with guide holes 39. There are two sets of guide holes 39 arranged symmetrically. The guide rod 37 is sleeved and connected to the inner wall of the guide hole 39.

[0030] The effects achieved by the above components are as follows: by setting the limiting groove 32, it is easy to prevent the sealing slide plate 33 from falling off the inner wall of the groove 31, and the movement trajectory of the sealing slide plate 33 can be constrained, so that it can slide stably along the opening trajectory of the limiting groove 32. The guide rod 37 is set so that the connecting plate 35 can slide stably along the surface of the guide rod 37, thereby changing the position of the sealing slide plate 33 and the opening and closing state of the groove 31. The tension spring 38 is set so that when the connecting plate 35 is unrestrained, the elastic force of the tension spring 38 can push the sealing slide plate 33 to move, so that the groove 31 remains closed.

[0031] Specifically, a magnetic suction plate 310 is fixedly connected to the surface of the connecting plate 35, and a magnetic suction slot 311 is opened on the surface of the fixing plate 36. The magnetic suction plate 310 is magnetically connected to the inner wall of the magnetic suction slot 311. A fixing block 312 is fixedly connected to the upper surface of the connecting plate 35. There are two sets of fixing blocks 312, which are symmetrically arranged.

[0032] Specifically, a rotating rod 313 is rotatably connected to the inner wall of the fixing block 312, a torsion spring 314 is fixedly connected to the surface of the fixing block 312, the torsion spring 314 is sleeved and connected to the surface of the rotating rod 313, an L-shaped clamping plate 315 is fixedly connected to the end of the torsion spring 314 away from the fixing block 312, the L-shaped clamping plate 315 is fixedly connected to the surface of the rotating rod 313, and a handle 316 is fixedly connected to the surface of the L-shaped clamping plate 315.

[0033] The effects achieved by the above components are as follows: by setting the connection between the magnetic suction plate 310 and the magnetic suction slot 311, it is easy to make the connecting block stably fixed to the surface of the fixing plate 36, fix the position of the sealing slide plate 33, and keep the slot 31 stably sealed. The torsion spring 314 is set so that after the L-shaped card plate 315 loses its force, the deformation elastic force of the torsion spring 314 can keep the L-shaped card plate 315 stably folded at a right angle, so that the L-shaped card plate 315 is stably engaged with the fixing plate 36, fix the position of the sealing slide plate 33, and keep the slot 31 open.

[0034] Working principle: By setting auxiliary device 3, the use of sealing slide plate 33 is more convenient when the main body of the heat preservation furnace 1 is subjected to explosion-proof treatment. When the L-shaped plate 315 is not subjected to external force, the elastic force of tension spring 38 can push the L-shaped plate 315 to magnetically connect with the fixed plate 36. When the internal temperature and air pressure of the heat preservation furnace 1 are too high, pull handle 316, and then magnetic plate 310 will disengage from magnetic slot 311, so that handle 316 drives L-shaped plate 315 to rotate along the axis of rotating rod 313. Then, torsion spring 314 is deformed by force, and then connecting plate 35 slides stably along the surface of guide rod 37, so that tension spring 38 is deformed and compressed. Then, connecting plate 35 drives sealing plate to slide stably along the opening trajectory of limit slide groove 32, so that slot 31 is in the open state.

[0035] Then, the handle 316 is released, causing the torsion spring 314 to lose its restraint and drive the L-shaped clamping plate 315 to rotate. Subsequently, the L-shaped clamping plate 315 engages with the surface of the fixing plate 36, fixing the position of the sealing slide plate 33. By setting the auxiliary device 3, it is convenient to carry out explosion-proof treatment on the main body of the heat preservation furnace 1, avoiding the existing heat preservation furnace from having excessively high internal temperature and pressure after prolonged use. During long-term heat preservation and heating, high-temperature molten material splashes, causing fires or burns to personnel, and in severe cases, the furnace body may explode, which consumes more materials and shortens the equipment life. This effectively improves the safety of the equipment.
