Description

Technical Field

[0001] This utility model relates to the field of metal parts inspection technology, and in particular to a dust collection and recovery device for a high-frequency induction combustion furnace used for metal parts inspection. Background Technology

[0002] The high-frequency induction combustion furnace for metal parts inspection is a device used in the field of metal material composition analysis and testing. Based on the principle of high-frequency induction heating, it can generate high temperatures in a short time, causing the metal parts to burn rapidly and completely, releasing the elements to be detected, such as carbon and sulfur. By combining it with matching analytical instruments, the gases produced by combustion are analyzed, thereby accurately determining the content of relevant elements in the metal parts, providing an important basis for the quality assessment and performance analysis of metal parts.

[0003] A search revealed Chinese patent publication number CN217032021U, which discloses a high-frequency induction combustion furnace for carbon content detection testing. The furnace includes a furnace body with a combustion chamber, a lifting cylinder, and a cooling and dust removal assembly. The lifting cylinder moves a carbon-containing platform into the combustion chamber for carbon content detection. After detection, the lifting cylinder lowers the carbon ash-containing platform through a connection hole into an installation groove. With the cooperation of the platform, metal block, extrusion plate, extrusion airbag, and spring, gas from the extrusion airbag enters a water storage chamber, increasing the pressure and causing water to enter the outlet pipe. The water is then sprayed into the installation groove. Because the outlet pipe is circumferentially located within the installation groove, it provides more comprehensive cooling and cleaning of the platform. However, in this prior art, powder recovery efficiency is low, especially in its ability to capture micron-sized particles. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dust collection and recovery device for a high-frequency induction combustion furnace for metal part inspection, aiming to improve the low powder recovery efficiency in the prior art, especially the insufficient ability to capture micron-sized particles.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a dust collection device for a high-frequency induction combustion furnace for metal part detection, comprising a combustion furnace body, a furnace door rotatably connected to the front side of the combustion furnace body, a combustion chamber connected to the left front end of the furnace door, a rotating rod rotatably connected to the rear bottom of the combustion chamber, a guide plate fixedly connected to the bottom of the rotating rod, a collection chamber connected to the bottom of the combustion chamber, a fan installed at the front inside the collection chamber, a guide pipe connected to the bottom of the collection chamber, a filter box connected to the bottom of the guide pipe, a box bottom slidably connected to the outer bottom of the filter box, a metal mesh fixedly connected to the top inside the filter box, a high-efficiency filter installed in the middle inside the filter box, an activated carbon adsorption layer installed at the bottom inside the filter box, and a moving mechanism installed on the front side of the filter box for moving the box bottom.

[0006] Through the above technical solution: the mixture of combustion gas and powder enters the combustion chamber, and under the action of the fan, it enters the powder collection chamber along the guide plate. Large powder particles settle, and the remaining gas and fine powder enter the filter box through the guide pipe. After passing through the metal mesh primary filter, high-efficiency filter and activated carbon adsorption layer, the clean gas is discharged, thus realizing the recovery of powder.

[0007] As a further description of the above technical solution: The moving mechanism includes an arc-shaped groove formed at the bottom front side of the filter box. Sliding blocks are fixedly connected to the top left and right ends of the front side of the filter box bottom. A rotating cylinder is fixedly connected to the middle front side of the filter box. Connecting rods are rotatably connected to the left and right ends of the rotating cylinder. Locking rods are slidably connected to the left and right ends of the middle front side of the filter box.

Sliding blocks are fixedly connected to the left and right ends of the front front side of the filter box bottom. The top of the sliding blocks is slidably connected to the outer bottom of the connecting rod.

[0008] The above technical solution allows for the following: when moving the bottom of the filter box, the fixed circular plate is pulled out and slids in the arc groove, causing the locking rod to slide. The connecting rod rotates around the rotating cylinder, and the rotating ring moves with the locking rod. The connecting rod moves synchronously, and the connecting rod moves from both ends to the middle. The bottom slides out of the sliding groove block, realizing the movement and disassembly of the bottom of the filter box, which facilitates cleaning of the filter box.

[0009] As a further description of the above technical solution: The front side of the collection chamber has multiple heat dissipation holes at equal intervals, and the right end of the rotating rod is fixedly connected to a turntable.

[0010] The above technical solution facilitates the rotation of the rotating rod by installing a turntable.

[0011] As a further description of the above technical solution: A handle is fixedly connected to the middle of the right side of the front of the furnace door, and support legs are fixedly connected to the four corners of the bottom of the combustion furnace.

[0012] The above technical solution facilitates the opening and closing of the furnace door by installing handles, and allows the combustion furnace to be kept away from the ground by installing support legs.

[0013] As a further description of the above technical solution: An instrument panel is installed at the center of the left side of the front of the furnace door, and a knob is installed at the bottom of the instrument panel.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a dust collection and recovery device for a high-frequency induction combustion furnace used for metal part detection. The device includes a combustion furnace body 1, a furnace door 9 rotatably connected to the front side of the combustion furnace body 1, a combustion chamber 16 connected to the left front end of the furnace door 9, a rotating rod 23 rotatably connected to the rear bottom of the combustion chamber 16, a guide plate 22 fixedly connected to the bottom of the rotating rod 23, a collection chamber 15 connected to the bottom of the combustion chamber 16, a fan 18 installed at the front inside the collection chamber 15 to facilitate dust collection, a guide pipe 13 connected to the bottom of the collection chamber 15, a filter box 11 connected to the bottom of the guide pipe 13, a box bottom 12 slidably connected to the outer bottom of the filter box 11, and a metal mesh fixedly connected to the top inner side of the filter box 11. 21. A high-efficiency filter 19 is installed in the middle of the inner side of the filter box 11. An activated carbon adsorption layer 20 is installed at the bottom of the inner side of the filter box 11. A moving mechanism 2 is installed on the front side of the filter box 11. The moving mechanism 2 is used to move the bottom 12 of the box. Multiple heat dissipation holes 14 are equidistantly opened on the front side of the collection chamber 15. A turntable 24 is fixedly connected to the right end of the rotating rod 23. The installation of the turntable 24 facilitates the rotation of the rotating rod 23. An instrument panel 6 is installed in the middle of the left side of the front side of the furnace door 9. A knob 7 is installed at the bottom of the instrument panel 6. The installation of the knob 7 facilitates the adjustment of the gear of this device. Two instrument panels 5 are installed on the top of the left side of the front side of the furnace door 9. A heat dissipation pipe 17 is connected to the top of the combustion chamber 16. The installation of the heat dissipation pipe 17 facilitates the heat dissipation of this device. Specifically, after the high-temperature gas and powder mixture from combustion enter the combustion chamber 16, the mixed airflow, under the action of the fan 18, enters the powder collection chamber 15 along the inclined guide plate 22. Since the guide plate 22 is set at the optimal inclination angle of 30 to 40 degrees, it can ensure smooth airflow and effectively reduce the flow velocity, allowing large powder particles in the mixed airflow to settle fully under the action of gravity and finally accumulate at the bottom of the powder collection chamber 15. Subsequently, the remaining gas containing trace amounts of fine powder enters the filter box 11 through the guide pipe 13, where it undergoes three stages of precision filtration: first, primary filtration through the metal mesh 21 to intercept larger particles; then, high-efficiency filter 19 for efficient interception; and finally, activated carbon adsorption layer 20 to adsorb residual harmful gases and odors. Through the above processes, the gas finally meets emission standards, while the intercepted powder is recycled in stages. To ensure the long-term stable operation of the system, operators need to regularly clean the accumulated material in the powder collection chamber 15 to prevent accumulation from affecting the separation effect. At the same time, the filter elements must be replaced strictly according to the maintenance cycle to ensure the filtration efficiency and safe use of the device.

[0027] Reference Figure 1 , Figure 3 and Figure 5The moving mechanism 2 includes an arc-shaped groove 208, which is opened at the bottom front side of the filter box 11. The top left and right sides of the front side of the box bottom 12 are fixedly connected to sliding blocks 207. The middle front side of the filter box 11 is fixedly connected to a rotating cylinder 201. The left and right sides of the rotating cylinder 201 are rotatably connected to connecting rods 202. The left and right sides of the middle front side of the filter box 11 are slidably connected to locking rods 204. The middle of the locking rod 204 passes through the middle of the rod 202. The front side of the locking rod 204 is fixedly connected to a fixing plate 205. The opening of the arc-shaped groove 208 facilitates the movement of the locking rod 204. The outer front end of the locking rod 204 is rotatably connected to a rotating ring 203. The bottom of the rotating ring 203 is fixedly connected to a connecting rod 206. The left and right sides of the front side of the box bottom 12 are fixedly connected to sliding blocks 207. The top of the sliding blocks 207 is slidably connected to the bottom outer side of the connecting rod 206. Specifically, when it is necessary to move or disassemble the bottom 12 of the filter box 11, the operator first grasps the fixed circular plate 205 and pulls it outwards moderately, causing it to slide along the arc groove 208 on the mounting base. This will cause the locking rod 204 connected to the fixed circular plate 205 to move synchronously in the guide groove on the front side of the filter box 11. Since the locking rod 204 passes through the central shaft hole of the connecting circular rod 202, the connecting circular rod 202 will rotate around the rotating cylinder 201 as a fulcrum during the sliding process. At this time, the locking rod 204 will move in a circular motion. 4. The rotating ring 203 at the front end will be linked, and the connecting rod 206 connected to its bottom will also be displaced. As the operation continues, the connecting rod 206 will gradually move from the starting position on both sides to the middle. During this process, the slider at the bottom of the connecting rod 206 and the guide rail at the top of the slide block 207 will always maintain sliding contact until it is completely separated from the range of the slide block 207. At this time, the locking of the bottom of the box 12 will be released, and the operator can smoothly move the bottom of the box 12 out, which will facilitate the thorough cleaning and maintenance of the inside of the filter box 11.

[0028] Reference Figure 1 , Figure 2 and Figure 3 A handle 8 is fixedly connected to the middle of the right side of the furnace door 9. Support legs 10 are fixedly connected to the four corners of the bottom of the combustion furnace body 1. A slot plate 4 is fixedly connected to the top left side of the combustion furnace body 1. A notice board 3 is installed inside the slot plate 4. Specifically, the installation of handle 8 facilitates the opening and closing of furnace door 9; the installation of support leg 10 allows the combustion furnace body 1 to be kept away from the ground; the installation of slot plate 4 facilitates the replacement of notice board 3; and the installation of notice board 3 facilitates reminders to staff.

[0029] Working principle: The mixture of combustion gas and powder enters the combustion chamber 16 and, under the action of the fan 18, enters the powder collection chamber 15 along the guide plate 22. Large powder particles settle to the bottom of the collection chamber 15 due to gravity. The remaining gas and fine powder enter the filter box 11 through the guide pipe 13, and pass through the metal mesh 21 for primary filtration, the high-efficiency filter 19 and the activated carbon adsorption layer 20 in sequence. Finally, the clean gas is discharged and the powder is efficiently recovered. When installing the guide plate 22, adjust the angle to 30 to 40 degrees. Clean the powder collection chamber 15 regularly to avoid accumulation. Replace the high-efficiency filter 19 after each number of sample tests. Check the activated carbon adsorption layer 20 monthly and replace it as needed. When it is necessary to move the bottom of the filter box 12, first pull the fixed circular plate 205 outward a bit, and then slide it inside the arc groove 208, causing the locking rod 204 to slide on the front side of the filter box 11. Since the locking rod 204 passes through the middle of the connecting circular rod 202, the connecting circular rod 202 rotates around the rotating cylinder 201. The rotating ring 203 connected to the front side of the locking rod 204 moves with the locking rod 204, and the connecting rod 206 fixedly connected to the bottom of the rotating ring 203 also moves synchronously. When the connecting rod 206 moves from both ends to the middle, its bottom will slide against the top of the sliding block 207 until it slides out, thus realizing the movement and disassembly of the bottom of the filter box 12, which is convenient for cleaning the filter box 11.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
