Description

Technical Field

[0001] This utility model relates to the field of metal casting smelting technology, specifically to a metal casting smelting and impurity removal device. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling, an object with a certain shape, size and performance is obtained. In the casting process, the metal required to make the casting needs to be melted into liquid metal and then poured into the mold.

[0003] Publication number CN211823802U discloses a metal casting raw material melting device. This device uses a motor, which drives a slider via a lead screw to slide inside a groove. The slider raises and lowers the furnace cover, allowing for convenient and stable opening and closing of the furnace cover. The device features a compact structure, reasonable design, and is suitable for widespread application. It also incorporates a waste gas suction cup and a filter cartridge. The waste gas suction cup ensures that the waste gas generated during casting processing and melting is fully and efficiently absorbed and discharged, while the filter cartridge effectively filters the smelting waste gas, improving the working environment for workers. However, this patent still has the following problems in practical use:

[0004] The device is connected to a rotating shaft via a bearing inside the rotating shaft seat. A smelting furnace is welded to the outer wall of one end of the rotating shaft. A handwheel is welded to the other end of the rotating shaft away from the smelting furnace. A sponge sleeve is fitted onto the outer wall of the handwheel to improve the operator's comfort when turning the handwheel. At the same time, the handwheel can rotate the smelting furnace via the rotating shaft. Although the device can achieve rapid rotation and unloading of the smelting furnace, it requires the operator to hold the handwheel and operate it continuously to achieve the unloading operation, which increases the operator's workload. If the operator's hand shakes or the hand is accidentally dropped due to external force, the smelting furnace may tip over uncontrollably, increasing the danger of using the device.

[0005] A metal casting smelting and impurity removal device is proposed to solve the problems mentioned above. Utility Model Content

The current device has a rotating shaft connected to the inside of the rotating shaft seat by a bearing, and a smelting furnace is welded to the outer wall of one end of the rotating shaft. A handwheel is welded to the other end of one of the rotating shafts away from the smelting furnace. A sponge sleeve is fitted on the outer wall of the handwheel to improve the comfort of the operator when turning the handwheel. At the same time, the handwheel can turn the smelting furnace through the rotating shaft. Although this device can realize the rapid turning and unloading of the smelting furnace, it requires the operator to hold the handwheel and operate it continuously to achieve the unloading operation, which increases the workload of the operator. If the operator's hand shakes or the hand is accidentally dropped by external force, the smelting furnace may tip over uncontrollably.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a metal casting smelting and impurity removal device, comprising a support frame, a smelting furnace arranged on the inner side of the support frame, a furnace cover arranged on the top of the smelting furnace, and an exhaust pipe fixedly installed inside the furnace cover; an adjustment mechanism is provided between the support frame and the smelting furnace, and a collection component is provided at the bottom inner side of the support frame;

[0008] The adjustment mechanism includes rotating columns symmetrically fixedly installed on both sides of the smelting furnace. One end of each rotating column passes through a support frame and is rotatably connected to the support frame. Heating tubes are fixedly installed inside the smelting furnace. A large gear is fixedly installed at the end of the rotating column away from the smelting furnace. An arc-shaped plate is fixedly installed on one side of the support frame, and a scale groove is opened on one side of the arc-shaped plate. A pointer is welded to one side of the large gear. A fixed box is fixedly installed on one side of the support frame, and a drive rod is rotatably connected between the fixed box and the support frame. A small gear is fixedly installed on the outside of one end of the drive rod. A worm gear is rotatably connected inside the fixed box, and a worm wheel is fixedly installed on the outside of the drive rod.

[0009] Preferably, an electric telescopic rod is fixedly installed on the top of the support frame, and connecting plates are symmetrically fixedly installed on both sides of the top of the furnace cover. The output end of the electric telescopic rod is fixedly connected to the bottom of the connecting plate. Limiting tubes are symmetrically fixedly installed on both sides of the support frame, and a limiting rod is slidably connected inside the limiting tube. A first retraction spring is sleeved on the outer side of the top of the limiting rod, and the top of the limiting rod is fixedly connected to the connecting plate.

[0010] Preferably, the collection assembly includes a collection box disposed inside the support frame, and universal wheels are symmetrically fixedly installed on one side of the bottom of the collection box. Limiting boxes are symmetrically embedded on both sides of the bottom of the support frame. A U-shaped rod is slidably connected inside the limiting box. Second retraction springs are symmetrically sleeved on both ends of the U-shaped rod. A movable plate is fixedly installed on one side of the U-shaped rod. An insert plate is welded to one side of the movable plate. Slots are symmetrically opened on both sides of the collection box, and the insert plate is inserted into the slot.

[0011] Preferably, a rotating disk is fixedly installed at one end of the worm gear.

[0012] Preferably, an annular sealing block is fixedly installed at the bottom of the furnace cover, and the outside of the annular sealing block is in close contact with the inside of the smelting furnace.

[0013] Preferably, a handle is fixedly installed on one side of the collection box.

[0014] Preferably, the large gear and the small gear are meshed together, and the worm and the worm wheel are meshed together.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This metal casting smelting and impurity removal device specifically includes the following: By having the operator rotate the worm gear, which drives the worm wheel to rotate, the small gear to rotate the large gear, and the large gear to rotate the pointer, the smelting furnace can be precisely tilted, allowing the molten metal to be quickly tilted and unloaded. This effectively avoids the temperature drop and secondary adsorption of impurities caused by prolonged stagnation of the molten metal. The self-locking function of the worm gear and worm wheel prevents the smelting furnace from changing its tilt angle due to operator error. By having the operator pull two sets of U-shaped rods to slide inside the limit box, the extension and reset properties of the second contraction spring allow the insertion plate to connect with the slot, thus achieving the effect of quickly fixing and disassembling the collection box. This greatly improves the efficiency of collecting and transferring molten metal and enhances the flexibility of equipment use.

[0016] 1. By rotating the worm gear, the operator drives the worm wheel, which in turn drives the drive rod. The drive rod then drives the pinion, which in turn drives the large gear. The large gear, in turn, drives the pointer, which in turn drives the rotating column. These two rotating columns cause the melting furnace to rotate. Simultaneously, the operator observes the pointer and the scale groove to control the furnace's angle rotation. This allows for precise tilting of the furnace, enabling rapid unloading of the molten metal and effectively preventing temperature drops caused by prolonged stagnation. The secondary adsorption of impurities utilizes the self-locking function of the worm gear and worm wheel to prevent operator error from causing changes in the tilt angle of the smelting furnace. By activating the electric telescopic rod, the connecting plate moves longitudinally, which in turn moves the furnace cover. At this time, the furnace cover and the smelting furnace are closed or separated. The movement of the connecting plate causes the limiting rod to slide inside the limiting tube. At this time, the first contraction spring contracts or extends, thereby achieving the effect of quickly closing or opening the furnace cover and the smelting furnace. This facilitates the operator to add or unload materials inside the smelting furnace, greatly improving the flexibility and efficiency of the equipment during use.

[0017] 2. The worker inserts the collection box into the inside of the support frame, and then pulls two sets of U-shaped rods to slide inside the limiting box. The movement of the U-shaped rods compresses the two sets of second contraction springs. By releasing the U-shaped rods, the worker uses the extension and reset properties of the second contraction springs to allow the insert plate to be inserted into the slot. This enables the collection box to be quickly fixed and disassembled, greatly improving the efficiency of collecting and transferring molten metal and increasing the flexibility of equipment use.

[0026] Please see Figure 1-6 The present invention provides a technical solution: a metal casting smelting and impurity removal device, including a support frame 1, a smelting furnace 101 is provided on the inner side of the support frame 1, and a furnace cover 102 is provided on the top of the smelting furnace 101, and an exhaust pipe 103 is fixedly installed inside the furnace cover 102; an adjustment mechanism 2 is provided between the support frame 1 and the smelting furnace 101, and a collection component 3 is provided at the bottom inner side of the support frame 1;

[0027] The adjusting mechanism 2 includes rotating columns 201 symmetrically fixedly installed on both sides of the smelting furnace 101.

[0029] The collection assembly 3 includes a collection box 301 disposed inside the support frame 1. A caster wheel 302 is symmetrically fixedly installed on one side of the bottom of the collection box 301. Limiting boxes 303 are symmetrically embedded on both sides of the bottom of the support frame 1. A U-shaped rod 304 is slidably connected inside the limiting box 303. Second retraction springs 305 are symmetrically sleeved on both ends of the U-shaped rod 304. A movable plate 306 is fixedly installed on one side of the U-shaped rod 304.

Slots 308 are symmetrically opened on both sides of the collection box 301, and the insert plate 307 is inserted into the slots 308. A handle 309 is fixedly installed on one side of the collection box 301, enabling quick fixing and disassembly of the collection box 301. This greatly improves the efficiency of collecting and transferring molten metal, and enhances the flexibility of equipment use. The support frame 1 and the collection box 301 can be threaded together using external bolts, further increasing the stability of the collection box 301 during use.

[0030] Working principle: Before using this metal casting smelting and impurity removal device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, the operator first pours the metal raw material into the melting chamber of the smelting furnace 101. The metal raw material is heated and impurities removed using evenly spaced electric heating tubes 202. Power is supplied to the electrical equipment via an external power supply module, and the operation of the electrical equipment is controlled by a controller. The operator rotates the worm gear 210, which drives the worm wheel 211. The rotation of the worm wheel 211 drives the drive rod 208, which in turn drives the pinion 209. The pinion 209 then drives the large gear 203, which in turn drives the pointer 206. The large gear 203 then drives the rotating column 201. At this time, the two rotating columns 201 rotate the smelting furnace 101. Simultaneously, the operator observes the pointer 206 and the scale groove 205 to control the angle rotation of the smelting furnace 101, thus achieving precise tilting of the smelting furnace 101. This allows for rapid tilting and unloading of the molten metal, effectively preventing the molten metal from being discharged due to prolonged exposure. The temperature drop and secondary adsorption of impurities caused by time delay are mitigated by the self-locking function of the worm gear 210 and worm wheel 211, preventing operator error from causing changes in the tilt angle of the smelting furnace 101. The operator activates the electric telescopic rod 212, which drives the longitudinal movement of the connecting plate 213. The movement of the connecting plate 213 causes the furnace cover 102 to move, closing or separating the furnace cover 102 from the smelting furnace 101. The movement of the connecting plate 213 causes the limiting rod 215 to slide inside the limiting tube 214, at which point the first contraction spring 216 contracts or extends, thus achieving the effect of quickly closing or opening the furnace cover 102 from the smelting furnace 101. This facilitates the operator's addition or unloading of materials inside the smelting furnace 101, greatly improving the flexibility and efficiency of the device. The design of the rotating disk 217 facilitates the operation of the worm gear 210, and the design of the annular sealing block 218 improves the sealing between the furnace cover 102 and the smelting furnace 101.

[0031] The worker inserts the collection box 301 into the inside of the support frame 1, and then pulls the two sets of U-shaped rods 304 to slide inside the limiting box 303. The movement of the U-shaped rods 304 compresses the two sets of second contraction springs 305. By releasing the U-shaped rods 304, the worker uses the extension and reset property of the second contraction springs 305 to make the insert plate 307 and the slot 308 fit together, thereby achieving the effect of quickly fixing and disassembling the collection box 301, which greatly improves the efficiency of the worker in collecting and transferring molten metal and increases the flexibility of the equipment during use.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
