Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or reference letters in the various examples, which have been repeated for purposes of simplicity and clarity and do not in themselves dictate a relationship between the various embodiments and/or arrangements discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.
Referring to fig. 1-2, the spraying tower for ceramic production provided by the present invention comprises a tower body 1, a hot air pipe 2 connected to the top of the tower body, a plurality of nozzles 3 arranged at the lower part of the tower body, and an exhaust pipe 4; the lower end of the tower body 1 is provided with a feed opening 1.1, and the nozzles 3 are uniformly distributed along the circumferential direction of the tower body; the outlet of the hot air pipe 2 is provided with a spherical crown-shaped air-equalizing shell 5, and air outlet holes are uniformly formed in the air-equalizing shell; a jet flow impact cone 6 is arranged at the outlet of the tower body, which is opposite to each nozzle 3.
When the tower works, hot air flows out of the hot air pipe 2 and is then uniformly distributed by the spherical crown-shaped air distribution shell 5, so that the hot air flows out uniformly in all directions, the temperature distribution uniformity of the inner space of the tower body is improved, and the powder is dried uniformly; the mud can impact on the jet flow impact cone 6 after being sprayed out from the nozzle 3, so that the mud is dispersed in a conical surface shape, the contact area with hot gas is greatly increased, and the drying efficiency is improved. Compared with the prior art, the spray tower for ceramic production has the advantages of higher drying efficiency, more uniform powder drying and better drying effect.
Furthermore, all jet impact cones 6 are connected to a mounting ring 7, which is connected to the tower 1 by a plurality of connecting rods 7.1.
In some embodiments, the lower end of the tower body 1 is a conical part 1.1, an outer conical shell 8 is sleeved outside the conical part 1.1, and the lower end of the outer conical shell is provided with a discharge hole 8.1; a partition plate 9 is arranged between the upper part of the outer cone shell 8 and the conical part 1.1, a plurality of vent holes are uniformly formed in the partition plate, the upper part of the outer cone shell 8 is divided into an annular cavity 10 by the partition plate 9, and the exhaust pipe 4 is connected in the annular cavity.
In the existing spraying tower for ceramic production, the exhaust pipe 4 is usually directly connected with the lower part of the tower body 1, so a large amount of powder is often taken out during exhaust, thereby causing waste and environmental pollution; here, the air will rise along the outer conical shell 8 after coming out of the conical part 1.1, then pass through the partition plate 9 to enter the annular cavity 10, and finally be discharged from the exhaust pipe 4, and part of the powder will be separated from the air during the rising process of the air along the outer conical shell 8, and then the powder content in the air can be greatly reduced by filtering through the partition plate 9.
Further, a grid plate 11 is arranged in the discharge hole 8.1. In real time, the dried powder often has the caking phenomenon; here, the powder will hit the grid plate when falling down, thereby scattering the agglomerated powder and avoiding the output of the agglomerated powder.
Preferably, the grid plate 11 is pivotally connected to the discharge opening 8.1, and a motor 12 for driving the grid plate 11 to rotate is disposed on the discharge opening 8.1. After the powder falls on the grid plate 11, part of the powder is accumulated on the grid plate 11, and the powder may be blocked after a long time, and the accumulated powder can be dropped by periodically turning the grid plate 11 (for example, 180 degrees) by the motor 12, so that the blocking can be avoided.
Specifically, as shown in fig. 2, the grid plate 11 includes a circular frame 11.1 and a plurality of steel wires 11.2 connected to the inner side of the circular frame; the steel wires are mutually perpendicularly crossed to form a grid. The thickness of the steel wire 11.2 is small, powder can be effectively scattered, and the steel wire is round and is not easy to accumulate powder.
Further, the grid plate 11 further comprises two rotating shafts 11.3 arranged on two sides of the circular frame 11.1, and the two rotating shafts 11.3 are arranged on an extension line of a certain diameter of the circular frame 11.1; two rotating shafts 11.3 are rotatably connected with the discharge hole 8.1, and one rotating shaft 11.3 is in driving connection with the motor 12.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-mentioned preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and the embodiments are substantially the same as the present invention.
