Description

Technical Field

[0001] This utility model relates to the field of zirconia bead production technology, specifically an environmentally friendly sintering furnace for zirconia bead production. Background Technology

[0002] Zirconia beads are a type of jewelry material with a high-density chemical structure, strong structure, small thermal volume, and clean surface. They are synthesized from zirconium and oxygen elements through high-temperature sintering in a sintering furnace and complex chemical reactions, resulting in high strength and resistance to damage. During the high-temperature sintering process, the sintering furnace produces a large amount of flue gas. To address this, the sintering furnace is typically equipped with a flue gas filtration device.

[0003] However, the existing flue gas filtration devices for sintering furnaces have too simple a structure. They only filter the flue gas generated by the sintering furnace through a single filtration device, resulting in incomplete filtration. Some harmful substances contained in the flue gas are still emitted into the atmosphere, causing environmental pollution. Furthermore, the filter components of the sintering furnace filtration devices are mostly installed inside the filtration equipment, making it inconvenient to replace them later. Utility Model Content

[0004] In order to solve the problem that the existing flue gas filtration devices for sintering furnaces are too simple in structure, resulting in incomplete flue gas filtration and environmental pollution, the purpose of this utility model is to provide an environmentally friendly sintering furnace for the production of zirconia beads.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an environmentally friendly sintering furnace for the production of zirconia beads, comprising a sintering furnace body, a fixing frame fixedly installed on the top surface of the sintering furnace body, a filter box fixedly installed on the top surface of the fixing frame, an exhaust pipe fixedly installed on one side of the top surface of the sintering furnace body, the end of the exhaust pipe away from the sintering furnace body fixedly installed inside the filter box, a first filter device installed inside the filter box, the first filter device comprising a mounting frame, the mounting frame being slidably installed inside the filter box, two clamping frames being symmetrically installed inside the mounting frame, and filter cotton installed between the two clamping frames inside the mounting frame;

[0006] A second filter device is installed inside one side of the top surface of the filter box. The second filter device includes a storage frame. The storage frame slides with damping inside one side of the top surface of the filter box. Filter screens are fixedly installed on both sides of the storage frame. An exhaust fan is installed in the middle of one side of the filter box. An exhaust pipe is fixedly installed on the filter box on the side of the exhaust fan. The exhaust pipe cooperates with the exhaust fan.

A pick-and-place slot is opened on one side of the storage frame, and a sealing cover is installed with damping on one side of the top surface of the storage frame. The sealing cover cooperates with the pick-and-place slot.

[0008] Preferably, a fixing member is fixedly installed at one end of the bottom surface of the mounting frame, and a fixing buckle is threaded in the fixing member. The fixing buckle passes through the fixing member and is threaded in the mounting frame. Limiting grooves are symmetrically opened on both sides of the top surface of the mounting frame, and the positioning strip is slidably engaged in the limiting groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, with the cooperation of the first and second filter devices in the filter box, the flue gas generated by the sintering furnace body is fully filtered before being discharged into the atmosphere, thereby reducing the pollution of the environment caused by the flue gas generated by the sintering furnace body.

The activated carbon is stored in the storage frame 51 by the filter screens 52 installed on both sides of the storage frame 51. When the sintering furnace body 1 is working, the flue gas generated in the sintering furnace body 1 is discharged through the exhaust pipe 11. The exhaust fan 31 is turned on. Under the operation of the exhaust fan 31, the flue gas discharged through the exhaust pipe 11 enters the filter box 3 through the exhaust pipe 11. The flue gas enters the filter box 3 and is filtered once by the filter cotton 43 of the first filter device 4. After filtration, it is purified a second time by the activated carbon stored between the two filter screens 52 in the second filter device 5. After purification, it is discharged into the atmosphere through the discharge pipe 32.

[0023] Positioning strips 44 are fixedly installed on both sides of the two clamping frames 42. The positioning strips 44 are slidably engaged within the mounting frame 41. A pick-and-place slot 53 is provided on one side of the storage frame 51. A sealing cover 54 is installed with damping on one side of the top surface of the storage frame 51. The sealing cover 54 cooperates with the pick-and-place slot 53. With the cooperation of the positioning strips 44 installed on both sides of the two clamping frames 42, the two clamping frames 42 are installed and positioned within the mounting frame 41, thereby completing the installation and fixation of the filter cotton 43 within the mounting frame 41. Remove the filter cotton 43 from the filter box 3 and use the positioning strip 44 to remove the clamping frame 42 that holds the filter cotton 43 from the mounting frame 41. This completes the disassembly and replacement of the filter cotton 43. Open the sealing cover 54 and, with the cooperation of the two filter screens 52, place the activated carbon for filtering the flue gas into the storage frame 51 through the pick-and-place slot 53. The activated carbon will then be used to filter the flue gas in conjunction with the two filter screens 52. Remove the storage frame 51 from the filter box 3 and open the sealing cover 54. The activated carbon for filtering the flue gas can then be replaced through the pick-and-place slot 53.

The handle 413 cooperates with the mounting frame 41, and the handle 413 facilitates the retrieval and placement of the mounting frame 41 in the filter box 3. A lifting groove 541 is opened in the middle of the top surface of the sealing cover 54. A handle 511 is fixedly installed in the middle of the top surface of the storage frame 51. The lifting groove 541 facilitates the opening and closing of the sealing cover 54 to the retrieval and placement groove 53. The handle 511 facilitates the retrieval and placement of the storage frame 51 in the filter box 3. Support seats 12 are symmetrically installed on the bottom surface of the sintering furnace body 1. There are two support seats 12. The sintering furnace body 1 is placed in the designated area for the sintering of zirconia beads by means of the two support seats 12.

[0026] Working principle: With the cooperation of the positioning strips 44 installed on both sides of the two clamping frames 42, the two clamping frames 42 are installed and positioned in the mounting frame 41, thereby completing the installation and fixation of the filter cotton 43 in the mounting frame 41.

[0027] When the sintering furnace body 1 is working, the flue gas generated inside the sintering furnace body 1 is discharged through the exhaust pipe 11. When the exhaust fan 31 is turned on, the flue gas discharged through the exhaust pipe 11 enters the filter box 3 through the exhaust pipe 11. The flue gas enters the filter box 3 and is filtered once through the filter cotton 43 of the first filter device 4. After filtration, it is purified a second time through the activated carbon stored between the two filter screens 52 in the second filter device 5. After purification, it is discharged into the atmosphere through the discharge pipe 32.

[0028] Remove the mounting frame 41 from the filter box 3, and use the positioning strip 44 to remove the clamping frame 42 that fixes the filter cotton 43 from the mounting frame 41.
