Description

Technical Field

[0001] This utility model relates to the field of smoke removal device technology, and in particular to a medium-frequency electric furnace with a smoke removal device. Background Technology

[0002] Medium frequency electric furnace is an important piece of equipment for melting cast iron in casting production. It melts cast iron blocks into molten iron, pours it into a sand mold, and after cooling, opens the mold to obtain castings. Announcement No. CN207439177U discloses a cast iron medium-frequency electric furnace with a dust removal device, including a furnace body mounted on a lifting platform. A waste heat recovery mechanism is located on one side of the furnace body, comprising a waste heat recovery tank. One end of a flue gas pipe extends into the waste heat recovery tank through a connection port, and the other end is connected to one side of the bottom of the waste heat recovery tank. A molten metal outlet is located on the upper side wall of the furnace body. A dust removal device is also installed on the furnace body, including a connecting plate positioned above the molten metal outlet. A dust removal hood is located below the connecting plate and above the molten metal outlet. The dust removal hood is connected to a high-temperature resistant hose, which passes through the connecting plate and is connected to the flue gas pipe via an exhaust fan. This invention solves the technical problem of a large amount of smoke and dust overflowing from the molten metal outlet when the furnace body pours molten metal, causing environmental pollution and affecting the health of employees. However, during the use of the above technologies, when the annular rubber baffle of the drain pipe and connecting pipe filters the water discharged from the drain pipe, long-term use may cause gap blockage or impurities to accumulate on one side of the drain pipe, resulting in poor drainage. It is necessary to remove the annular rubber baffle for cleaning. However, the drain pipe and the outlet pipe are fixed by bolts, which makes the disassembly work inconvenient and time-consuming. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] The present invention adopts the following technical solution: a medium-frequency electric furnace with a smoke removal device, comprising a base, a furnace body and a dust removal chamber fixedly connected to the surface of the base, a smoke exhaust pipe fixedly connected between the dust removal chamber and the furnace body, a blower provided on the surface of the smoke exhaust pipe, an exhaust pipe fixedly connected to the top of the dust removal chamber, an installation groove provided on the surface of the dust removal chamber, a dust removal plate provided inside the installation groove, a water inlet pipe and a water outlet pipe fixedly connected to the surface of the dust removal chamber, a first valve body fixedly connected to the surface of the water inlet pipe, and a second valve body and a filter assembly fixedly connected to the surface of the water outlet pipe.

[0005] Preferably, the filter assembly includes a filter chamber with a square groove on its surface and an opening at the bottom. A filter plate is disposed inside the opening. A fixing block is fixedly connected to the surface of the filter chamber, and a screw is threadedly connected to the inside of the fixing block. A locking block is fixedly connected to the surface of the screw, and an adjusting knob is fixedly connected to the bottom of the screw. A handle is fixedly connected to the surface of the filter plate. This design allows for the filtration of wastewater discharged from the dust removal chamber while also facilitating the disassembly and cleaning of the filter plate, preventing clogging of the filter plate's gaps and ensuring effective drainage.

[0006] Preferably, the surface of the adjustment knob is fixedly connected with anti-slip ribs, which are evenly distributed on the surface of the adjustment knob. This increases the friction between the knob and the hand when adjusting it, preventing slippage during rotation.

[0007] Preferably, a sealing gasket made of rubber is provided inside the square groove. This improves the seal between the filter plate and the square groove, preventing water leakage.

[0008] Preferably, there are two sets of locking blocks, which are symmetrically distributed on both sides of the center of the filter chamber surface. This improves the stability of fixing the filter plate.

[0009] Preferably, a limiting block is fixedly connected to the surface of the filter chamber, and the locking block is engaged between two sets of limiting blocks. Here, the locking block engaged on the filter plate can be limited to prevent the locking block from shifting, so as not to affect the fixing effect on the filter plate.

[0010] Preferably, a slag discharge pipe is fixedly connected to the bottom of the filter chamber, and a sealing cap is threaded onto the surface of the slag discharge pipe. This allows impurities accumulated inside the filter chamber to be discharged, preventing a large accumulation of impurities that could affect the water output efficiency of the valve body. Furthermore, it eliminates the need to disassemble the drain pipe, greatly improving the convenience and efficiency of impurity cleaning.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model, by setting a fixing block, screw, adjusting knob, and locking block structure, allows the filter plate to be removed from the filter chamber for cleaning after prolonged use. After closing the second valve, the adjusting knob is rotated, causing the screw to rotate within the fixing block and simultaneously pushing the locking block upwards. The locking block is then rotated so that it is no longer above the surface of the filter chamber, allowing the filter plate to be removed. This fixes the filter plate and facilitates its disassembly and cleaning, making subsequent disassembly and cleaning more convenient and efficient, and shortening the time required for cleaning.

[0013] 2. In this utility model, by setting up a slag discharge pipe and a sealing cover, when a certain amount of impurities accumulate inside the filter chamber, the No. 2 valve body is closed, and then the sealing cover is unscrewed from the slag discharge pipe. Then, the No. 2 valve body is slowly opened, so that wastewater can flow out from the slag discharge pipe, flushing out the impurities accumulated inside the filter chamber. This achieves the discharge of impurities accumulated inside the filter chamber, preventing a large amount of impurities from accumulating inside the filter chamber and affecting the water output efficiency of the valve body.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] Please see Figure 1-5 This utility model provides a technical solution: a medium-frequency electric furnace with a smoke removal device, including a base 1, a furnace body 2 and a dust removal chamber 3 fixedly connected to the surface of the base 1, a smoke exhaust pipe 4 fixedly connected between the dust removal chamber 3 and the furnace body 2, a blower 5 provided on the surface of the smoke exhaust pipe 4, an exhaust pipe 6 fixedly connected to the top of the dust removal chamber 3, an installation groove 13 opened on the surface of the dust removal chamber 3, a dust removal plate 12 inside the installation groove 13, a water inlet pipe 7 and a water outlet pipe 8 fixedly connected to the surface of the dust removal chamber 3, a first valve body 9 fixedly connected to the surface of the water inlet pipe 7, a second valve body 10 and a filter assembly fixedly connected to the surface of the water outlet pipe 8, the filter assembly including a filter chamber 11, a square groove 14 opened on the surface of the filter chamber 11, a slot 15 opened at the bottom of the square groove 14, a filter plate 16 provided inside the slot 15, a fixing block 19 fixedly connected to the surface of the filter chamber 11, a screw 20 threadedly connected inside the fixing block 19, and a locking block fixedly connected to the surface of the screw 20. 21. An adjustment knob 22 is fixedly connected to the bottom of the screw 20, and a handle 17 is fixedly connected to the surface of the filter plate 16. This handle can filter the wastewater discharged from the dust removal chamber 3 and also facilitate the disassembly and cleaning of the filter plate 16 later, so as to prevent the gaps of the filter plate 16 from being blocked and affecting the drainage effect. Anti-slip ribs 23 are fixedly connected to the surface of the adjustment knob 22. The anti-slip ribs 23 are evenly distributed on the surface of the adjustment knob 22. This can increase the friction between the adjustment knob 22 and the hand when rotating the adjustment knob 22, so as to prevent slippage. A sealing gasket 18 is provided inside the square groove 14. The sealing gasket 18 is made of rubber. This can improve the sealing between the filter plate 16 and the square groove 14 and prevent water leakage. There are two sets of locking blocks 21. The locking blocks 21 are symmetrically distributed on both sides of the middle of the surface of the filter chamber 11. This can improve the stability of fixing the filter plate 16.

[0025] Example 2

[0026] Please see Figure 4-5 A limiting block 26 is fixedly connected to the surface of the filter chamber 11. A locking block 21 is locked between two sets of limiting blocks. This can limit the locking block 21 on the filter plate 16 and prevent the locking block 21 from shifting, so as not to affect the fixing effect of the filter plate 16. A slag discharge pipe 24 is fixedly connected to the bottom of the filter chamber 11. A sealing cap 25 is threadedly connected to the surface of the slag discharge pipe 24. This can discharge the impurities accumulated inside the filter chamber 11, so as to prevent a large amount of impurities from accumulating inside the filter chamber 11 and affecting the water output efficiency of the valve body. At the same time, it is not necessary to disassemble the drain pipe, which greatly improves the convenience and efficiency of cleaning impurities.

[0027] Working principle: During use, first open valve 9 on water inlet pipe 7, then add water into dust removal chamber 3 through water inlet pipe 7. When furnace 2 is working, the generated flue gas is quickly transported to dust removal chamber 3 by blower 5 on exhaust pipe 4 and filtered by water and dust removal plate 12 in dust removal chamber 3, and finally discharged from exhaust pipe 6 at the top of dust removal chamber 3. When the water in dust removal chamber 3 needs to be replaced after long-term use, open valve 10 on water outlet pipe 8, and the wastewater in dust removal chamber 3 will pass through filter chamber 11 on drain pipe. After filtration by the filter plate 16, the wastewater is discharged. When a certain amount of impurities accumulate inside the filter chamber 11, the second valve body 10 is closed. Then, the sealing cap 25 is unscrewed from the slag discharge pipe 24, and the second valve body 10 is slowly opened to allow wastewater to flow out from the slag discharge pipe 24, flushing out the impurities accumulated inside the filter chamber 11. This allows the impurities accumulated inside the filter chamber 11 to be discharged, preventing a large accumulation of impurities inside the filter chamber 11, which could affect the water output efficiency of the valve body. After prolonged use, the filter plate 16 needs to be... To remove the filter plate 16 from the filter chamber 11 for cleaning, close the second valve body 10, then rotate the adjusting knob 22. The anti-slip ribs 23 on the adjusting knob 22 increase the friction when holding it. The adjusting knob 22 drives the screw 20 to rotate within the fixed block 19, simultaneously pushing the locking block 21 upwards. When the locking block 21 is higher than the height of the limit block 26, rotate the locking block 21 so that it is no longer above the surface of the filter chamber 11. Then, hold the handle 17 and remove the filter plate 16 from the filter chamber. The filter plate 16 is removed from the groove 15 on the upper part of the filter plate 11, which not only fixes the filter plate 16, but also facilitates its disassembly and assembly. This makes it easier to disassemble and clean the filter plate 16 later, which improves the convenience and efficiency of disassembly and cleaning of the filter plate 16 and shortens the time required for disassembly and cleaning of the filter plate 16. After the filter plate 16 is fixed to the filter chamber 11, the sealing gasket 18 in the groove 14 on the upper part of the filter plate 16 and the filter chamber 11 can improve the sealing between the filter plate 16 and the filter chamber 11.
