Description

Technical Field

[0001] This utility model relates to the technical field of sintering furnaces, and in particular to a ceramic filler sintering furnace. Background Technology

[0002] Ceramic packings, as important functional materials in the industrial field, are widely used in packed towers, reactors and filtration devices in industries such as chemical, environmental protection and energy.

[0003] Sintering, a crucial step in ceramic manufacturing, is the process of forming dense polycrystalline ceramic powder green bodies through mass migration at high temperatures. Traditional ceramic filler sintering typically employs box furnaces or tunnel kilns. Traditional resistance heating requires first heating the furnace air, then transferring heat to the ceramic green body through heat conduction and convection, enabling the green body to achieve intergranular bonding and densification at high temperatures.

[0004] Traditional resistance heating requires heating the air in the furnace first, and then transferring the heat to the ceramic blank through heat conduction and convection. This process generates a large amount of waste gas, such as nitrogen oxides and sulfur dioxide. These waste gases, once released into the atmosphere, severely pollute the environment, affect air quality, and harm human health. Utility Model Content

[0005] The purpose of this invention is to provide a ceramic filler sintering furnace to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0008] In some embodiments, a blower box is provided on the side of the filter box away from the liquid storage tank, and a blower is provided inside the blower box. The blower is fixedly connected to a gas supply pipe at its gas delivery end, and one end of the gas supply pipe extends into the interior of the sintering furnace body.

[0009] In some embodiments, the top of the liquid storage tank is provided with a liquid filling port, and the top of the filter block is provided with a hinged door.

[0025] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Given that current technologies, traditional resistance heating methods require heating the furnace air first, and then transferring the heat to the ceramic blank through heat conduction and convection, this process generates a large amount of waste gas, such as nitrogen oxides and sulfur dioxide. These waste gases, once released into the atmosphere, severely pollute the environment, affect air quality, and pose a threat to human health.

[0028] like Figure 1-5 As shown, this utility model embodiment provides a ceramic filler sintering furnace, including a base plate 1, a support base 101 fixedly connected to the top of the base plate 1, a sintering furnace body 102 fixedly connected to the top of the support base 101, an inner liner 103 fixedly connected inside the sintering furnace body 102, a filter box 3 provided on one side of the sintering furnace body 102, round holes 301 provided on both sides of the filter box 3, a liquid storage tank 501 provided inside the filter box 3, a partition plate 502 fixedly connected to one side of the liquid storage tank 501, a flow channel 503 provided between the partition plate 502 and the filter box 3, a filter block 504 provided on the side of the flow channel 503 away from the liquid storage tank 501, and an air suction pipe 5 fixedly connected to the top of the liquid storage tank 501, one end of the air suction pipe 5 extending into the interior of the sintering furnace body 102.

[0029] When the ceramic packing sintering furnace is in operation, the inner liner 103 inside the furnace body 102 is used to hold the ceramic packing to be sintered. The filter box 3 serves to filter and collect gases. The liquid storage tank 501 is connected to the inside of the furnace body 102 through the suction pipe 5. During the sintering process, gases or potentially volatile substances generated inside the furnace body 102 are drawn into the liquid storage tank 501 through the suction pipe 5. The partition 502 separates the liquid storage tank 501 from the flow channel 503. Gas flows from the liquid storage tank 501 through the flow channel 503 to the filter block 504. The filter block 504 filters the gas, removing impurities and harmful substances. The filtered gas is then discharged through the round hole 301.

[0030] The solvent in the storage tank 501 is ammonia or urea solution, which reduces nitrogen oxides to nitrogen and water, achieving a denitrification efficiency of over 90%. The filter block 504 is limestone, which absorbs sulfur dioxide and generates gypsum, achieving a desulfurization efficiency of over 95%.

[0031] This design effectively collects and processes the gases generated during sintering, preventing harmful gases from being directly emitted into the surrounding environment and reducing environmental pollution.

[0032] Furthermore, a blower box 4 is provided on the side of the filter box 3 away from the liquid storage tank 501. A blower 401 is provided inside the blower box 4. An air supply pipe 402 is fixedly connected to the air supply end of the blower 401. One end of the air supply pipe 402 extends into the interior of the sintering furnace body 102.

[0033] After the sintering furnace body 102 has finished working, the blower 401 in the air box 4 is started, and the outside air is transported into the sintering furnace body 102 through the air supply pipe 402 connected to the air supply end. At this time, the air will be transmitted to the liquid storage tank 501 through the air supply pipe 402.

[0034] Furthermore, the top of the liquid storage tank 501 is provided with a liquid filling port 505, and the top of the filter block 504 is provided with a hinged door 506.

[0035] The liquid inlet 505 on the top of the liquid storage tank 501 is used to add liquid for absorbing or treating gases into the liquid storage tank 501. The door 506 on the top of the filter block 504 is hinged, so the door 506 can be opened to facilitate operation of the filter block 504 when it is necessary to replace or clean it.

[0036] Furthermore, a cleaning mechanism 2 is provided inside the sintering furnace body 102. The cleaning mechanism 2 includes a furnace door 201. The furnace door 201 is sealed and connected to one side of the sintering furnace body 102. A support plate 202 is fixedly connected to one end of the furnace door 201. A scraper 203 is fixedly connected to one end of the support plate 202. The scraper 203 and the support plate 202 are located inside the inner liner 103.

[0037] After sintering, the inner liner 103 inside the sintering furnace body 102 needs to be cleaned. The furnace door 201 in the cleaning mechanism 2 is sealed to one side of the sintering furnace body 102. When the furnace door 201 moves to one side, the support plate 202 and the scraper 203 fixed to one end of the support plate 202 enter the interior of the inner liner 103. By moving the support plate 202 and the scraper 203, the residues adhering to the inner wall of the inner liner 103 can be scraped off, preventing the residues from affecting the next sintering process and improving the sintering quality.

[0038] Furthermore, a connecting rod 205 is fixedly connected to the bottom of the furnace door 201, and a moving block 206 is fixedly connected to the bottom of the connecting rod 205. A lead screw 207 is threadedly connected to the inside of the moving block 206, and one end of the lead screw 207 is fixedly connected to the output end of the motor 208.

[0039] After the motor 208 starts, its output end drives the lead screw 207 to rotate. The moving block 206 is internally threaded onto the lead screw 207. The rotation of the lead screw 207 causes the moving block 206 to move along the axial direction of the lead screw 207. The connecting rod 205 fixes the moving block 206 to the bottom of the furnace door 201. Therefore, the movement of the moving block 206 will drive the furnace door 201, the support plate 202, and the scraper 203 to move together, realizing the cleaning action of the scraper 203 inside the inner liner 103.

[0040] Furthermore, the top of the base plate 1 is provided with a limiting groove 209, which is slidably connected to the moving block 206.

[0041] The setting of the limiting groove 209 can improve the operational stability of the cleaning mechanism 2 and ensure that the scraper 203 can accurately clean the inner wall of the inner liner 103 along the predetermined trajectory.

[0042] Furthermore, the inner side of the scraper 203 is provided with a slope surface 204, and the scraper 203 is made of silicon nitride ceramic.

[0043] During the cleaning process, the inclined surface 204 on the inner side of the scraper 203 can better contact the residues adhering to the inner wall of the inner liner 103, and smoothly scrape off the residues. The scraper 203 is made of silicon nitride ceramic material, which has the characteristics of high hardness, good wear resistance, and high temperature resistance.

[0044] Furthermore, a sealing cap is provided at the liquid filling port 505. The sealing cap at the liquid filling port 505 is used to seal the liquid filling port 505 when no liquid needs to be added, so as to prevent liquid leakage in the liquid storage tank 501.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
