Description

Technical Field

[0001] This utility model relates to the field of induction furnace technology, specifically to a medium-frequency induction furnace with residue prevention. Background Technology

[0002] A medium-frequency induction furnace is a device that rectifies three-phase AC power into DC power, then converts the DC power into an adjustable current, which is supplied to the alternating current flowing through the capacitor and induction coil. This generates high-density magnetic lines of force in the induction coil, which cut the metal material placed inside the coil. Large eddy currents are generated in the metal material. These eddy currents also have some properties of medium-frequency current, namely, the free electrons in the metal itself flow in the resistive metal body to generate heat. This equipment is needed in the production process of diesel engine casings.

[0003] Currently, many medium-frequency induction furnaces have a fixed structure. During the process of pouring molten metal into the mold, a large amount of molten metal often remains on the furnace wall. If this is not handled in time, the molten metal can easily cool and adhere to the furnace wall, hindering the heating of raw materials for diesel engine casing production in the next cycle. This increases the time required to heat and melt the raw materials for diesel engine casing production, thereby reducing the efficiency of diesel engine casing production. Therefore, corresponding improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a medium-frequency induction furnace that prevents residue buildup, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medium-frequency induction furnace with residue prevention, comprising a furnace body for processing a diesel engine casing, wherein a liquid collection trough is provided on the inner wall of the bottom end of the furnace body near the edge, and a base plate for placing the furnace body on the ground. The furnace body is installed at the middle position of the top end of the base plate, and a liquid storage cylinder is installed at one side position of the top end of the base plate. A drain pipe is connected to one side surface of the liquid storage cylinder, and a pump is installed at the other side surface of the liquid storage cylinder. One end of the pump is connected to a connecting pipe, and one end of the connecting pipe is connected to a circular pipe. Several sets of suction pipes are connected to the inner wall of the circular pipe. A cover plate is provided at the top end of the furnace body, and a motor is embedded in the top end of the cover plate. The output end of the motor is driven by a main gear, and a secondary gear is meshed with the side surface of the main gear. A rotating rod is installed at the bottom end of the secondary gear, and a connecting plate is installed at the bottom end of the rotating rod. A scraper is installed at one end of the connecting plate.

[0006] Preferably, a number of mounting holes are provided on the side surface of the furnace body near the bottom, and one end of the liquid extraction pipe passes through the mounting holes into the interior of the furnace body and extends into the interior of the liquid collection tank.

[0007] Preferably, a control valve is installed on the side surface of the drain pipe, and the circular pipe is located on the outside of the furnace body and is arranged around the furnace body.

[0008] Preferably, the top of the cover plate is provided with a liquid injection port on the side near the motor.

[0009] Preferably, a through hole is provided inside the cover plate near the position of the rotating rod, and one end of the rotating rod passes through the through hole into the interior of the cover plate and extends into the interior of the furnace body.

[0010] Preferably, both the connecting plate and the scraper are located inside the furnace body, and one side surface of the scraper is fitted against the inner wall of the furnace body.

[0011] Preferably, the outer surface of the rotating rod is rotatably connected to the through hole inside the cover plate via a bearing ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating components such as a storage tank, drain pipe, pump, connecting pipe, circular pipe, suction pipe, cover plate, motor, main gear, auxiliary gear, rotating rod, connecting plate, scraper, and injection port, the problem of large amounts of molten metal remaining on the furnace walls of existing medium-frequency induction furnaces can be effectively solved.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To achieve the above objectives, according to Figures 1-4 As shown, this utility model provides the following technical solution: a medium-frequency induction furnace with residue prevention, comprising a furnace body 1 for processing a diesel engine casing, wherein a liquid collection tank 11 is provided on the inner wall of the bottom end of the furnace body 1 near the edge, and a base plate 2 for placing the furnace body 1 on the ground, wherein the furnace body 1 is installed at the middle position of the top end of the base plate 2, and a liquid storage tank 21 is installed at one side of the top end of the base plate 2, wherein a drain pipe 22 is connected to one side of the side surface of the liquid storage tank 21, and a drain pipe 22 is connected to the other side of the side surface of the liquid storage tank 21. A liquid pump 23 is installed, with a connecting pipe 24 connected to one end of the pump 23, and a circular pipe 25 connected to the other end of the connecting pipe 24. A control valve is installed on the side surface of the drain pipe 22. The circular pipe 25 is located on the outside of the furnace body 1 and is arranged around the furnace body 1. Several sets of liquid extraction pipes 26 are connected to the inner wall of the circular pipe 25. Several sets of mounting holes 12 are opened on the side surface of the furnace body 1 near the bottom. One end of the liquid extraction pipe 26 passes through the mounting hole 12, penetrates the interior of the furnace body 1, and extends into the interior of the liquid collection tank 11.

[0021] A cover plate 3 is provided at the top of the furnace body 1. A motor 31 is embedded in the top of the cover plate 3, and the output end of the motor 31 is connected to a main gear 32. A secondary gear 33 is meshed with the side surface of the main gear 32, and a rotating rod 34 is installed at the bottom of the secondary gear 33. The outer surface of the rotating rod 34 is rotatably connected to a through hole opened inside the cover plate 3 through a bearing ring. A through hole is opened inside the cover plate 3 near the position of the rotating rod 34, and one end of the rotating rod 34 passes through the through hole and extends into the interior of the furnace body 1. A connecting plate 35 is installed at the bottom of the rotating rod 34, and a scraper 36 is installed at one end of the connecting plate 35. Both the connecting plate 35 and the scraper 36 are located inside the furnace body 1, and one side surface of the scraper 36 is attached to the inner wall of the furnace body 1. A liquid injection port 37 is provided at the top of the cover plate 3 near the side of the motor 31.

[0022] During use, molten metal for producing diesel engine housings can be injected into the furnace body 1 through the injection port 37. During injection, molten metal inevitably remains on the inner wall of the furnace body 1. At this time, the operator can start the motor 31, causing the main gear 32 to rotate accordingly. This, in turn, causes the secondary gear 33 and the rotating rod 34 to rotate, thereby causing the connecting plate 35 and the scraper 36 to rotate accordingly. Since one side of the scraper 36 is in contact with the inner wall of the furnace body 1, the scraper 36 can scrape the molten metal from the inner wall of the furnace body 1 while rotating. In addition, under the influence of gravity, the molten metal will flow downward into the interior of the collection tank 11. After that, the user can start the pump 23. Under the operation of the pump 23, the molten metal inside the collection tank 11 can be sucked into the interior of the circular tube 25 through several sets of suction pipes 26. The molten metal can be injected into the interior of the storage cylinder 21 for collection through the connecting pipe 24. After collection, the control valve on the outer surface of the drain pipe 22 can be opened to discharge the molten metal inside the storage cylinder 21. The above component settings and operations can prevent the molten metal inside the furnace body 1 from leaving residue.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
