Description

Technical Field

[0001] The present invention relates to the technical field of ceramic colorant production, and specifically to a two-stage rapid firing ceramic colorant kiln and its use method. Background Art

[0002] Ceramic colorants are functional inorganic pigments synthesized by high-temperature solid-phase reactions in the ceramic industry. Their core function is to achieve selective light absorption through solid solution or crystal encapsulation structures formed by metal oxides and carrier minerals, endowing ceramic products with stable and rich colors. High-quality colorants need to have characteristics such as high temperature resistance, acid and alkali resistance, environmental protection, and good dispersibility, and are widely used in fields such as glaze decoration, body coloring, and penetrating ink.

[0003] The calcination process is the core link in the preparation of ceramic colorants and can directly affect the product performance. If the calcination process is not properly controlled, problems such as crystal structure defects, uneven color development, or incomplete curing of heavy metals may occur, affecting the product qualification rate and environmental protection performance. Therefore, precisely controlling the calcination temperature, atmosphere, and time, and optimizing the process parameters in combination with an intelligent control system are the key technical paths to improve the color rendering stability of ceramic colorants. When using traditional ceramic colorant firing kilns, generally, ceramic colorants are mixed in a certain proportion, then loaded into saggers, and the saggers are placed inside the firing kiln for firing. After firing, a series of processes such as crushing and fine crushing are carried out, and finally, the colorant finished products are obtained.

[0004] In the prior art, during the firing process of raw materials, waste gas with a large amount of heat and particles remains inside the firing kiln, and traditional firing kilns do not have measures to properly handle it, and generally, it is directly discharged; however, directly discharging waste gas with heat and particles into the atmosphere is likely to cause pollution to the surrounding air environment, and thus have a certain impact on the lives and physical health of surrounding residents; secondly, when firing the raw materials inside the sagger, problems such as inconsistent heating curves of the raw materials inside the sagger (the heating rate of the materials near the outer wall of the sagger is significantly higher than that of the materials in the central area of the sagger) and uneven heating are likely to occur, resulting in poor product quality and low production stability of the produced materials, and subsequent re-firing is also required, wasting time and energy.

The output end of the second motor 808 is connected with a second spur gear 807. The second toothed ring 806 is in contact with the second spur gear 807. The bottom of the preheating kiln 802 is fixedly connected with an exhaust pipe 809. A blower 810 is installed on the outer wall of the exhaust pipe 809.

[0038] The preheating mechanism 8 further includes a connecting pipe 811. The connecting pipe 811 is fixedly connected to the preheating kiln 802. The connecting pipe 811 is arranged at the discharging end of the preheating furnace chamber 805 and is connected to the feeding end of the firing furnace chamber 3. An installation seat 812 is fixedly connected to the outer wall of the connecting pipe 811. One end of the preheating furnace chamber 805 is fixedly connected to a rotating cylinder 813. A first bevel gear 814 is arranged on the outer wall of the port of the rotating cylinder 813. One end of the first bevel gear 814 is fixedly connected to a second bevel gear 815. The second bevel gear 815 is rotatably connected to the inside of the installation seat 812. A third bevel gear 816 is rotatably connected to the outer wall of the second bevel gear 815 inside the installation seat 812. One end of the third bevel gear 816 is fixedly connected to a feeding auger rotating shaft 817. Horizontally arranged plates 818 distributed in a circular pattern are fixedly connected to the inner wall of the preheating furnace chamber 805.

[0039] In this embodiment: Start the first motor 6. The first motor 6 operates to drive the first spur gear 5 to rotate. The first spur gear 5 rotates to drive the first toothed ring 4 to rotate. The first toothed ring 4 rotates to drive the firing furnace chamber 3 to perform a rotating operation. Start the second motor 808. The second motor 808 operates to drive the second spur gear 807 to rotate. The second spur gear 807 rotates to drive the second toothed ring 806 to rotate. The second toothed ring 806 rotates to drive the preheating furnace chamber 805 to rotate.

[0040] The raw materials in the feeding hopper 804 enter the preheating furnace chamber 805 and slide along the inner wall of the preheating furnace chamber 805 into the connecting pipe 811. At this time, the rotation of the preheating furnace chamber 805 drives the rotating cylinder 813 to rotate. The first bevel gear 814 driven by the rotation of the rotating cylinder 813 rotates. The first bevel gear 814 rotates to drive the second bevel gear 815 to rotate. The second bevel gear 815 rotates to drive the third bevel gear 816 to rotate. The third bevel gear 816 rotates to drive the feeding auger rotating shaft 817 to rotate. The feeding auger rotating shaft 817 rotates to push the raw materials to move through the connecting pipe 811 and enter the firing furnace chamber 3. The burner 7 operates to fire the raw materials in the firing furnace chamber 3. The generated flue gas enters the preheating kiln 802 through the flue 803 and then passes through the preheating furnace chamber 805 and is discharged through the exhaust pipe 809. The flue gas generated by firing can preheat the raw materials. Under the condition of high-temperature preheating, the volatile components are drawn away by the countercurrent flue gas through the fan 810. The rotation of the preheating furnace chamber 805 drives the horizontally arranged plates 818 to rotate synchronously. The rotating horizontally arranged plates 818 drive the raw materials to perform a turning motion, so that the raw materials can fully contact the flue gas while moving, facilitating the preheating operation of the raw materials and making the raw materials heated more evenly.

[0041] It should be noted that the outlet end pipe body of the feed hopper 804 is inserted into the feed end of the preheating furnace 805, and there is an air outlet gap between the feed end of the preheating furnace 805; similarly, there is an air inlet gap between the outlet end of the rotating cylinder 813 and the connecting pipe 811, so that the countercurrent flue gas can enter the inner cavity of the preheating kiln 802 through the flue 803, and then pass through the inner cavity of the preheating furnace 805 along the air inlet gap and the air outlet gap to complete the preheating operation.

[0042] In addition, by setting the starting of the first motor 6, the present invention can synchronously realize the overturning and conveying of materials in the preheating furnace 805, the auger conveying and discharging operation of the auger conveying rotating shaft 817, and the filter plate cleaning operation of the impurity removal box 901 in the subsequent purification mechanism, significantly saving the number of driving devices and achieving the purpose of energy conservation and consumption reduction.

[0043] Please refer specifically to Figures 6 to 10 , the purification mechanism 9 includes an impurity removal box 901 and an activated carbon filter box 902. The impurity removal box 901 and the activated carbon filter box 902 are sequentially connected in series on the exhaust pipe 809. A filter plate 903 is fixedly connected to the inner wall of the impurity removal box 901. A toothed disc 904 in contact with the second toothed ring 806 is rotatably connected inside the second base 801. One end of the toothed disc 904 is fixedly connected to a connecting shaft 905. One end of the connecting shaft 905 is fixedly connected to a fourth bevel gear 906. A fifth bevel gear 907 is arranged on the outer wall of the fourth bevel gear 906. One end of the fifth bevel gear 907 is fixedly connected to a reciprocating lead screw 908. The reciprocating lead screw 908 is rotatably connected to the top of the impurity removal box 901. The purification mechanism 9 further includes a displacement frame 909. The displacement frame 909 is slidably connected to the outer wall of the reciprocating lead screw 908. The bottom end of the displacement frame 909 extends into the inner cavity of the impurity removal box 901 and is fixedly connected to a displacement seat 910. A scraper 911 extending out of the displacement seat 910 is slidably connected inside the displacement seat 910. A spring 912 is connected between the scraper 911 and the displacement seat 910. An extrusion block 913 penetrating through the displacement seat 910 and the scraper 911 is slidably connected inside the displacement seat 910. A card slot 914 is opened at the bottom end of the scraper 911. A collection box 915 is installed at the bottom end of the impurity removal box 901.

[0044] In this embodiment: When the flue gas passes through the impurity removal box 901, the filter plate 903 filters the particulate matter in the flue gas. When passing through the activated carbon filter box 902, the activated carbon purifies the flue gas (the activated carbon in the activated carbon filter box 902 is in the form of carbon packets or carbon plates with filter holes and can be taken out and replaced after being used for a period of time). When the second gear ring 806 rotates, the rotation of the second gear ring 806 drives the gear disk 904 to rotate. The rotation of the gear disk 904 drives the connecting shaft 905 to rotate.

The rotation of the fifth bevel gear 907 drives the reciprocating lead screw 908 to rotate. The rotation of the reciprocating lead screw 908 drives the displacement frame 909 to perform up and down reciprocating displacement.

The scraper 911 is pressed against the filter plate 903 by the elastic force of the spring 912. The displacement of the displacement seat 910 drives the scraper 911 to displace, and the scraper 911 scrapes the outer wall of the filter plate 903, scraping the particulate impurities into the collection box 915 for collection operation; when the displacement seat 910 is displaced to the bottom end of the impurity removal box 901, the extrusion block 913 contacts the bottom end of the impurity removal box 901, and the extrusion block 913 is displaced under force. The displacement of the extrusion block 913 pushes the scraper 911 to displace, separating from the filter plate 903, squeezing the spring 912. At the same time, the bottom of the extrusion block 913 is engaged into the card slot 914 to fix the retraction position of the scraper 911. The top of the extrusion block 913 is displaced above the displacement seat 910; when the displacement seat 910 moves upward, the scraper 911 does not contact the filter plate 903; when the displacement seat 910 is displaced to the top end of the impurity removal box 901, the extrusion block 913 contacts and displaces with the impurity removal box 901, and the extrusion block 913 is displaced out of the card slot 914. The scraper 911 is displaced under the elastic force of the spring 912 and fits with the filter plate 903 again; this design facilitates the filtration and purification operation of the flue gas, and automatically cleans the particulate impurities on the filter plate 903, extending the effective service life of the impurity removal box 901 without frequent shutdown for cleaning.

The bottom outer walls of the two side grooves of the extrusion block 913 are in contact with the slope, and the inner wall of the card slot 914 is fitted with the bottom outer walls of the two side grooves of the extrusion block 913.

[0054] In this embodiment: When the displacement seat 910 is displaced to the bottom end of the impurity removal box 901, the extrusion block 913 contacts the bottom end of the impurity removal box 901. The extrusion block 913 is displaced under force. The displacement of the extrusion block 913 contacts the inclined surface and pushes the scraping plate 911 to retract, causing the scraping plate 911 to separate from the filter plate 903 and simultaneously squeezing the spring 912; until the bottom of the extrusion block 913 is snapped into the card slot 914 to fix the retracted position of the scraping plate 911.

[0055] The usage method of the two-stage rapid firing ceramic colorant kiln furnace is as follows:

[0056] Step 1: The raw materials in the feed hopper 804 enter the preheating furnace chamber 805. The second motor 808 is started to drive the preheating furnace chamber 805 to rotate. The raw materials slide along the preheating furnace chamber 805 and enter the firing furnace chamber 3 through the connecting pipe 811. The first motor 6 is started to drive the firing furnace chamber 3 to rotate;

[0057] Step 2: The burner 7 is started to heat the firing furnace chamber 3. The generated flue gas enters the preheating kiln 802 through the flue 803, then passes through the preheating furnace chamber 805 and is discharged through the exhaust pipe 809. The flue gas preheats the raw materials. Under the condition of high-temperature preheating, the volatile components are taken away by the countercurrent flue gas through the fan 810;

[0058] Step 3: The taken-away flue gas is purified when passing through the impurity removal box 901 and the activated carbon filter box 902.
