Description

Technical Field

[0001] This utility model belongs to the field of metal processing, specifically relating to a medium-frequency exhaust gas emission device. Background Technology

[0002] A medium-frequency melting furnace is an industrial electric furnace that uses medium-frequency current to generate an alternating magnetic field through an induction coil, which in turn induces current (eddy current) in the metal material placed in the furnace. The resistance heating effect generated by the eddy current is used to heat and melt the metal. However, when a medium-frequency melting furnace is in use, it will emit waste gas, so a waste gas emission device is used to treat and discharge the waste gas.

[0003] Most existing medium-frequency exhaust gas emission devices only have simple filtration structures to treat exhaust gas. Harmful substances filtered by the medium-frequency exhaust gas emission device can easily fall back into the smelting furnace, causing secondary pollution to the metal in the furnace and reducing the purity and quality of the metal materials. Therefore, this application proposes a medium-frequency exhaust gas emission device to solve the above-mentioned technical problems. Utility Model Content

[0032] 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.

[0033] Please see Figure 1-5 This utility model provides a medium-frequency exhaust gas emission device, including a mounting base plate 1;

[0034] The exhaust assembly 2 is permeable and disposed on the upper surface of the mounting base plate 1;

[0035] The receiving component 3, located inside the exhaust assembly 2, includes a mounting ring 31 located inside the exhaust assembly 2 and a sealing plate 34 slidably located inside the exhaust assembly 2.

[0036] The filter assembly 4 is detachably located inside the exhaust assembly 2 and is situated above the impurity receiving assembly 3.

[0037] In this embodiment, the present invention provides a medium-frequency exhaust gas emission device. Through the exhaust component 2, the exhaust gas generated by the medium-frequency melting furnace can be discharged into the air. Under the action of the filter component 4, harmful substances in the exhaust gas can be filtered and blocked. The collection component 3 can collect the harmful substances filtered and blocked by the filter component 4, thereby preventing harmful substances from falling back into the medium-frequency melting furnace.

[0038] Furthermore, such as Figure 2-3 As shown, the exhaust assembly 2 in the preferred embodiment of this utility model includes an exhaust pipe 21, which is permeable to the upper surface of the mounting base plate 1, and a mounting ring 31 is disposed inside the exhaust pipe 21; a smoke cap 22 is disposed on the upper end face of the exhaust pipe 21; a cleaning hole 23 is opened on the outer side of the exhaust pipe 21; a sliding groove 24 is opened on the inner side of the cleaning hole 23; a mounting hole 25 is opened on the outer side of the exhaust pipe 21, and the mounting hole 25 communicates with the inner side of the sliding groove 24; and a placement hole 26 is opened on the outer side of the exhaust pipe 21, and the placement hole 26 is located above the cleaning hole 23.

[0039] Furthermore, the sealing plate 34 is slidably disposed on the inner side of the sliding groove 24, and the outer side of the sealing plate 34 is in contact with the inner side of the sliding groove 24. In this way, when the sealing plate 34 is located in the sliding groove 24 and seals the cleaning hole 23, the exhaust gas in the exhaust pipe 21 will not flow out from the cleaning hole 23; the lower end of the exhaust pipe 21 is connected to the exhaust end of the medium frequency melting furnace.

[0040] In this embodiment, several preferred embodiments of the exhaust stack 21 are given. When the medium frequency melting furnace is in operation, the exhaust gas generated by the medium frequency melting furnace will be discharged into the air through the exhaust stack 21. When the exhaust gas flows in the exhaust stack 21, the filter component 4 installed in the exhaust stack 21 will treat the exhaust gas, thereby ensuring that the exhaust gas can be safely discharged into the air. Furthermore, under the action of the smoke cap 22, it can prevent rain or debris from falling into the exhaust stack 21 and also ensure that the exhaust gas in the exhaust stack 21 is discharged normally.

[0041] Furthermore, such as Figure 4 As shown, the mixing component 3 in the preferred embodiment of this utility model includes an air guide tube 32 disposed inside the mounting ring 31; a conical sleeve 33 disposed on the upper end face of the air guide tube 32; and a fixing bolt 35, which can be threadedly connected to the outer side of the sealing plate 34, and the fixing bolt 35 is located inside the mounting hole 25.

[0042] Furthermore, the air guide tube 32 is a tapered air guide tube, and the upper end dimension of the air guide tube 32 is smaller than the lower end dimension of the tapered sleeve 33; at least two support rods are symmetrically arranged on the inner side of the tapered sleeve 33, and the tapered sleeve 33 is arranged on the upper end face of the air guide tube 32 through at least two support rods.

[0043] Furthermore, the mounting plate is located on the front end face of the fixing bolt 35, and the rear surface of the mounting plate contacts the outer side of the exhaust pipe 21.

[0044] This embodiment provides several preferred embodiments of the receiving component 3. Through the air guide pipe 32, the exhaust gas in the exhaust stack 21 can flow upwards from the air guide pipe 32. When the exhaust gas in the exhaust stack 21 comes into contact with the filter component 4, the filter component 4 filters and blocks harmful substances in the exhaust gas. This causes large particles of harmful substances that are blocked to fall downwards under the influence of gravity. Simultaneously, the conical sleeve 33 prevents large particles of harmful substances from falling from the air guide pipe 32 into the medium-frequency melting point. Inside the furnace, contamination of the metal in the medium-frequency melting furnace reduces the purity and quality of the final metal material. The contaminants fall onto the mounting ring 31. When the medium-frequency melting furnace stops working, the fixing bolt 35 can be rotated so that the outer side of the mounting plate no longer contacts the outer side of the exhaust pipe 21. This allows the sealing plate 34 to move within the sliding groove 24, exposing the cleaning hole 23. This allows workers to clean large particles of harmful substances from the mounting ring 31. Conversely, reversing this operation seals the cleaning hole 23.

[0045] Furthermore, such as Figure 5 As shown, in the preferred embodiment of this utility model, the filter assembly 4 includes a fixing plate 41, which is detachably disposed inside the placement hole 26; and a filter module 42, which is disposed outside the fixing plate 41, and the outer side of the filter module 42 is in contact with the inner side of the exhaust pipe 21.

[0046] More specifically, the outer side of the fixing plate 41 is interference-fitted with the inner side of the placement hole 26, and is set in the placement hole 26 by locking bolts; the filter module 42 is existing known technology, therefore, the filter module 42 will not be described in detail in this technical solution.

[0047] In this embodiment, several preferred embodiments of the filter assembly 4 are given. The filter module 42 set on the fixing plate 41 can filter the exhaust gas in the exhaust pipe 21. The filter module 42 will block large particles of harmful substances, and the large particles of harmful substances will fall onto the mounting ring 31, so that the exhaust gas generated by the medium frequency melting furnace can be discharged into the air. The fixing plate 41 can be quickly removed from the placement hole 26 to replace the filter module 42, ensuring the filtration effect of the filter module 42 on the exhaust gas.

[0048] 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.
