Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary equipment for ceramic production, in particular to a novel ceramic product storage and cooling device. Background Art
[0002] After being fired during the production of ceramic utensils, they will enter the cooling process. The purpose of cooling ceramic utensils is mainly because the cooling process has a great influence on the grain size and crystal stress state in the fired green body. Cooling at a relatively fast speed can avoid the extension of the heat preservation section, maintain the number and size of grains, prevent the low-valence iron oxidation of ceramic products, and also improve the glaze gloss, whiteness, and mechanical strength, etc. The existing cooling methods for ceramic products after firing are generally divided into water cooling and air cooling. In the water cooling method, due to the too fast cooling rate and the inability to ensure that the cooling water can act on each end face of the ceramic product as much as possible at the same time, it is possible that the cooling rates and the degrees of thermal expansion and contraction of each face of the ceramic product are inconsistent, resulting in cracks on the surface of the ceramic product; in addition, after the cooling water enters the accommodation cavity inside the ceramic product, it will bring inconvenience to the subsequent cleaning work after cooling, which is not conducive to improving work efficiency. Compared with the water cooling method, the air cooling method acts on the corresponding faces of the ceramic product relatively more at the same time, and the cooling rate is not too fast, so the probability of cracks and the like occurring after the ceramic product is cooled is correspondingly reduced.
[0003] Although the existing air-cooled ceramic product equipment after firing (hereinafter referred to as air-cooled equipment) meets the production needs to a certain extent, due to the limitations of the equipment structure, there are still the following technical problems. Specifically, the existing air-cooled equipment generally directly allows the cold air output by an air compressor or a fan to enter from one end and exit from the other end. The multiple ceramic products to be cooled are fixed in multiple workstations inside the equipment. The entering cold air cannot enter the lower ends of the workstations and the ceramic products. There are more or less uneven heating and cooling and a risk of cracks at the lower, side, and upper ends of the ceramic products. In addition, the air entering the equipment is not evenly distributed in each area. That is to say, it is possible that the cooling rate of some ceramic products is relatively fast and the cooling rate of some ceramic products is relatively slow, which will still have some adverse effects on actual production (after cooling is completed within the specified unit time, it is possible that some ceramic products have not been cooled sufficiently). In summary, it is very necessary to provide a ceramic product storage and cooling device that can uniformly cool the lower and upper ends of multiple ceramic products to be cooled at the same time. Summary of the Utility Model
[0004] In order to overcome the drawbacks described in the background art due to the limitations of the structure and functions of existing air-cooling devices, the present utility model provides a novel ceramic product storage and cooling device which, under the combined action of relevant mechanisms, can cool the fired ceramic products to be cooled during rotation, enabling multiple ceramic products to be evenly cooled by cold air from above and below simultaneously, and minimizing the probability of cracks and other problems caused by uneven heat and cold on each surface of the ceramic products as much as possible.

[0007] Further, a sealing ring is installed between the inner and outer rings of the bearing.
[0008] Further, multiple air inlet holes are distributed on the surface of the part of the rotating pipe located inside the sleeve.
[0009] Further, each fixed shell includes a shell body, a limiting ring, and a spring.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: Multiple ceramic products to be cooled after firing can be respectively fixed in multiple shells of the present novelty (specifically, the staff pulls the limit ring to the right by hand to move it to the right, places the lower end of the ceramic product at the lower end inside the shell, and after releasing the hand, the limit ring fixes the ceramic product under the action of the spring); during cooling, the motor speed reduction mechanism drives the lower cooling cavity, the upper cooling cavity and multiple ceramic products to rotate, and the compressed air output by the air compressor is ejected at high speed through multiple ventilation holes in the lower cooling cavity and the upper cooling cavity, simultaneously cooling the lower end, side end and upper end of the ceramic product, and the hot air after cooling is discharged outwards from the upper end of the cooling bin.

The upper and lower parts of the right end of the cooling chamber 92 respectively have three threaded holes 95. Three manual bolts 96 are respectively screwed into the three threaded holes 95 through three openings at the upper and lower parts of the right end of the sealing door to seal and install the sealing door 94 at the front end of the cooling chamber 92; there is an opening in the middle of the right end of the installation chamber 91. The lower end of the motor reduction mechanism 1 is installed in the middle of the inner lower end of the installation chamber 91 through threads. The rotating air supply mechanism includes a rotating pipe 61, a sleeve 62, and two bearings 63. The outer rings of the two bearings 63 are respectively tightly sleeved on the upper and lower inner sides of the sleeve 62. A gas inlet pipe 64 that communicates with its interior is welded in the middle of the right end of the sleeve 62. The middle outer side of the gas inlet pipe 64 is hermetically installed in the opening in the middle of the right end of the installation chamber 91, and its right end is located outside the right end of the installation chamber 91. The outer part of the right end of the gas inlet pipe 64 is connected to the exhaust pipe of the air compressor's air storage tank through a pipeline; the inner rings of the two bearings 63 are respectively tightly sleeved on the lower end of the rotating pipe 61. The lower end of the rotating pipe 61 at the outer side of the sleeve is welded to the upper end of the rotating shaft of the motor reduction mechanism 1; there is an opening in the middle of the partition 9, and a bearing A97 is hermetically welded in the opening. The middle of the rotating pipe 61 is tightly sleeved on the inner ring of the bearing A97; the lower cooling cavity 2 and the upper cooling cavity 3 are hollow structures. There are multiple lower ventilation holes 7 at the upper end of the lower cooling cavity 2 and the lower end of the upper cooling cavity 3. There are openings in the middle of the upper and lower ends of the lower cooling cavity 2 and the middle of the lower end of the upper cooling cavity 3. The upper end of the rotating pipe 61 is hermetically welded to the outside of the opening at the lower end of the lower cooling cavity 2 and communicates with the inside of the lower cooling cavity 2.

The upper end of the connecting pipe 5 is hermetically welded to the outside of the opening at the lower end of the upper cooling cavity 3 and communicates with the inside of the upper cooling cavity 3; a upper shaft rod 98 is welded in the middle of the outer side of the upper end of the upper cooling cavity 3. The middle of the inner upper end of the cooling chamber is installed with a bearing seat 99 through bolts. The upper end of the upper shaft rod 98 is tightly sleeved in the bearing inner ring of the bearing seat 99; there are multiple fixed shells 4, and the lower ends of the multiple fixed shells 4 are respectively installed at the upper ends of multiple ventilation holes 7 in multiple lower cooling cavities.
[0018] Figure 1 ,2 As shown in Figures 1 and 3, sealing rings (to prevent gas escape) are respectively installed between the upper and lower ends of the inner and outer rings of bearing 63 and bearing A97. Multiple air intake holes 611 are distributed on the surface of the part of the rotating pipe 61 located inside the sleeve. Each fixed shell 4 includes a shell body 41, a limiting ring 42, and a spring 43. The upper end of the shell body 41 is of an open structure, and multiple ventilation holes 411 are provided at the lower end and the side end. There is an opening in the middle of the right side end of the shell body 41. A shaft rod 44 is horizontally welded in the middle of the right side end of the semi-circular arc-shaped limiting ring 42. The spring 43 is sleeved on the outer end of the shaft rod 44. The shaft rod 44 extends out of the right end of the shell body 41 through the opening, and an operating handle 45 (for conveniently pulling and operating the limiting ring 42) is welded on the outer side of the shaft rod. The limiting ring 42 of the fixed shell is located inside the shell body 41. When the limiting ring 42 is at the left dead center, the distance between the left side inside the shell body 41 and the left side of the limiting ring 42 is less than the outer diameter of the lower end of the ceramic product to be cooled (not shown in the figure). When the limiting ring 42 is at the right dead center, the distance between the left side inside the shell body 41 and the left side of the limiting ring 42 is greater than the outer diameter of the lower end of the ceramic product to be cooled. The lower ends of the shell bodies of multiple fixed shells 4 are respectively welded on multiple ventilation holes of the lower cooling cavity 2 and are in communication with the ventilation holes 7 inside. Multiple ventilation holes A421 are distributed on the surface of the limiting ring 42. Exhaust pipes 8 that are in communication with the inside are respectively welded on the left and right sides of the upper end of the cooling box.
[0019] Figure 1 、 2As shown in Figure 3, before using the new type, the staff loosens the three bolts 96 counterclockwise, then opens the sealing door 94 to the left, and fixes the lower ends of multiple ceramic products that need to be cooled in multiple fixed shells by hand (the staff wears heat-resistant gloves or uses corresponding manual clamps to clamp the ceramic products and place them in the fixed shell). Specifically, the staff pulls the limit ring 42 to the right through the handle 45 by hand, overcomes the elastic force of the spring 43 and moves to the right (the distance between the left end of the limit ring 42 and the left side of the shell 41 is greater than the outer diameter of the lower end of the ceramic product), and places the lower end of the ceramic product at the lower end of the shell. After releasing the hand, the limit ring 42 fixes the ceramic product under the elastic action of the spring 43 to the left. Due to the large elastic force, the ceramic product can be prevented from falling out of the fixed shell during rotation. When placing the ceramic product, for the fixed shell located at the rear end of the cooling lower cavity 2, the staff can temporarily turn on the power switch of the motor reduction mechanism 1, and the rotating shaft of the motor reduction mechanism 1 drives the rear end of the cooling lower cavity 2 to rotate to the front end, and turns off the power switch after it is in place, which is convenient for the staff to place the ceramic product. After all the ceramic products are placed and fixed in place, the staff closes the sealing door, screws the three manual bolts 96 into the three threaded holes 95 through the three openings at the upper and lower parts of the rear end of the sealing door, and seals the sealing door 94 on the front end of the cooling bin 92. Then the staff opens the valve of the air compressor air tank and the power switch of the motor reduction mechanism 1 respectively. The rotating shaft of the motor reduction mechanism 1 drives the cooling lower cavity 2, the cooling upper cavity 3, the fixed shell 4 and the ceramic products inside thereof to rotate through the rotating tube 61. At the same time, the compressed air output by the air compressor will enter the sleeve 62 through the air inlet pipe 64, and then enter the rotating tube 61 from the multiple air inlet holes 611 of the rotating tube. The air goes up through the rotating tube and the inner side of the connecting tube 5, and is ejected at a relatively fast speed through the multiple air vents 7 at the upper end of the cooling lower cavity 2 and the lower end of the cooling upper cavity 3. Since the side and lower ends of the fixed shell (which are connected to the air vents of the cooling lower cavity 2) have air vents 411 and the surface of the limiting ring has multiple air vents A421, the air at the lower end will act upward on the lower end and side ends of the ceramic product, and the air at the upper end will act downward on the upper end, side ends and inside of the ceramic product. The hot air after the upper and lower intersection cooling is discharged from the exhaust pipe 8 at the upper end of the cooling bin to the upper outer end. Since the present invention can cool the lower end, the side end and the upper end of the ceramic product at the same time, the probability of uneven heat and cold on each surface of the ceramic product causing cracks and the like is reduced as much as possible.
