Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically a dust removal device for a medium-frequency induction furnace. Background Technology

[0002] Medium-frequency induction furnaces are devices that rectify three-phase AC power into DC power, then convert the DC power into an adjustable current, which is supplied to the alternating current flowing through capacitors and induction coils. This generates high-density magnetic lines of force in the induction coil, cutting through the metal material placed inside and inducing large eddy currents within the metal. These eddy currents also exhibit some properties of medium-frequency currents. An existing dust removal device for medium-frequency induction furnaces (Announcement No.: CN215610167U) has the following drawbacks in use:

[0003] During use, the filter element is fixed inside the filter box with bolts. As impurities accumulate on the filter element, the pores become smaller, preventing gas or liquid from passing through smoothly. The filtration efficiency drops significantly. Disassembly requires the use of other tools to remove the bolts one by one, which is cumbersome. To address this issue, this patent proposes a dust removal device for a medium-frequency induction furnace. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device for a medium-frequency induction furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for a medium-frequency induction furnace, comprising a dust removal box, an installation plate fixed to the inner wall of the dust removal box, a conveying pipe installed through the installation plate, an insert inserted into the dust removal box, a sliding plate slidably connected to the inner wall of the insert near the dust removal box end, two connecting rods fixed to the top of the sliding plate, connecting blocks fixed to the inner walls of both sides of the dust removal box, multiple springs fixed between the bottom end of the sliding plate and the bottom end of the insert, a fixing ring fixed to the top of the sliding plate, an installation ring inserted into the fixing ring, a filter element fixed to the top of the installation ring, and an insert tube fixed to the top of the filter element, the insert tube being inserted into the outer wall of the conveying pipe.

[0006] Preferably, the inner wall of the fixing ring is provided with multiple sliding grooves, and the outer wall of the mounting ring is fixed with multiple fixing blocks, which are slidably connected in the sliding grooves.

[0007] Preferably, a fixing plate is fixed to the other end of the plug-in, a sliding opening is provided at the other end of the plug-in, a fixing rod is fixed to the top of the sliding plate, a push rod is fixed to the top of the fixing rod, and the push rod is slidably connected in the sliding opening.

[0008] Preferably, a fixing pipe is provided between the top of the mounting plate and the inner wall of the top of the dust collection box, one end of the fixing pipe is fixedly connected to a suction pipe, the suction pipe passes through the dust collection box, and the conveying pipe is fixedly connected to the bottom end of the fixing pipe.

[0009] Preferably, a fan is installed on one side of the dust collector, and the air inlet of the fan is fixedly connected to an installation pipe, which is fixedly connected to one side of the dust collector.

[0010] Preferably, a connecting plate is installed at one end of the dust collection box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By inserting the mounting ring at the bottom of the filter element into the fixing ring, and during insertion, the fixing block is inserted into the sliding groove and slides within the groove, thus achieving the limiting position. No bolts are needed for fixation, making operation convenient. Alternatively, the insert is inserted into the dust collector. During insertion, the connecting block presses against the connecting rod, causing the connecting rod to move the sliding plate downwards and compress the spring. When the sliding plate contacts the inner wall of the dust collector, the insertion tube at the top of the filter element is positioned below the conveying pipe. The connecting block then releases pressure on the connecting rod, and the spring moves the sliding plate upwards, inserting the insertion tube into the outer wall of the conveying pipe, thus limiting the filter element's position. The insert is also limited and cannot move forward or backward. To remove the filter element, press down on the push rod to move the sliding plate downwards, moving the insertion tube below the conveying pipe. Then, pull out the insert. Afterwards, rotate the filter element to allow the fixing block to slide within the groove. Once the fixing block reaches its end, move it upwards to remove the filter element. No additional tools are required, making the operation simple. Attached Figure Description

[0018] 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.

[0019] 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, cutting the metal material placed inside and creating large eddy currents within the metal material. These eddy currents also exhibit some properties of medium-frequency current. Existing medium-frequency induction furnaces often have an open top for the heating chamber. This design leads to the following problem: the open heating chamber causes a large amount of dust-laden air to escape from the furnace during heating, polluting the entire workshop environment. This invention provides a dust removal device for medium-frequency induction furnaces by installing a dust suction pipe 2 at the top of the heating chamber to remove dust from the top, preventing dust from spreading in the air and affecting the surrounding air quality.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a dust removal device for a medium-frequency induction furnace, including a dust removal box 1, an installation plate 8 fixed to the inner wall of the dust removal box 1, a conveying pipe 9 installed through the installation plate 8, an insert 4 inserted into the dust removal box 1, a sliding plate 13 slidably connected to the inner wall of the insert 4 near the dust removal box 1, two connecting rods 12 fixed to the top of the sliding plate 13, connecting blocks 11 fixed to the inner walls of both sides of the dust removal box 1, multiple springs 14 fixed between the bottom end of the sliding plate 13 and the bottom end of the insert 4, a fixing ring 16 fixed to the top of the sliding plate 13, an installation ring 15 inserted into the fixing ring 16, a filter element 10 fixed to the top of the installation ring 15, an insert tube fixed to the top of the filter element 10, and the insert tube inserted into the outer wall of the conveying pipe 9. The other end of the plug-in 4 is fixed with a fixing plate 5, and the other end of the plug-in 4 is provided with a sliding opening. The top of the slide plate 13 is fixed with a fixing rod, and the top of the fixing rod is fixed with a push rod 6. The push rod 6 is slidably connected in the sliding opening. The inner wall of the fixing ring 16 is provided with multiple sliding grooves 18. The outer wall of the mounting ring 15 is fixed with multiple fixing blocks 17, and the fixing blocks 17 are slidably connected in the sliding grooves 18.

[0021] It should be noted that by inserting the mounting ring 15 at the bottom of the filter element 10 into the fixing ring 16, and during the insertion process, inserting the fixing block 17 into the slide groove 18 and sliding within the slide groove 18, the limiting position can be achieved without the need for bolts for fixation, making the operation relatively convenient. Then, insert the plug 4 into the dust collector 1. During the insertion process, the connecting block 11 presses against the connecting rod 12, causing the connecting rod 12 to move the sliding plate 13 downwards, compressing the spring 14. When the sliding plate 13 contacts the inner wall of the dust collector 1, the insertion tube at the top of the filter element 10 is positioned just below the conveying pipe 9. The connecting block 11 no longer presses against the connecting rod 12, and the spring 14 drives the slide plate 13 to move upward, so that the insertion tube is inserted into the outer wall of the delivery pipe 9, thereby limiting the filter element 10. At the same time, the plug 4 is also limited and cannot move back and forth. When the filter element 10 needs to be removed, the slide plate 13 is moved downward by pressing the push rod 6 downward, and the insertion tube moves to the bottom of the delivery pipe 9. Then the plug 4 can be pulled out. After that, the filter element 10 is rotated so that the fixing block 17 slides in the slide groove 18. When the fixing block 17 slides to the end, it moves upward to remove the filter element 10.

[0022] like Figure 1 and Figure 2 As shown, a fixing pipe 7 is installed between the top of the mounting plate 8 and the inner wall of the top of the dust collection box 1. One end of the fixing pipe 7 is fixedly connected to a suction pipe 2, which passes through the dust collection box 1. The conveying pipe 9 is fixedly connected to the bottom end of the fixing pipe 7. A fan 19 is installed on one side of the dust collection box 1. The air inlet of the fan 19 is fixedly connected to an mounting pipe, which is fixedly connected to one side of the dust collection box 1. A connecting plate 3 is installed at one end of the dust collection box 1.

[0023] It should be noted that the dust on the top of the heating chamber of the medium frequency induction furnace is sucked away by the fan 19, and then sent into the fixed pipe 7 through the dust suction pipe 2. It then enters the filter element 10 through the delivery pipe 9 and the insertion pipe for filtration. The filtered air is discharged through the installation pipe to achieve the dust removal effect.

[0024] 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 embodiments and their equivalents.
