Description

Technical Field

[0001] The utility model relates to the technical field of water spray atomizers for granulating ceramsite sand, in particular to a water spray atomizer for granulating ceramsite sand. Background Art

[0002] Ceramic sand, also known as oil fracturing proppant, is made by sintering various raw materials such as clay, slate, bauxite and industrial solid waste. In the preparation process of ceramsite sand, the mined raw materials need to be crushed, ground and mixed, and then granulated by a granulator, and then calcined into ceramsite sand by a rotary kiln. Ceramic sand is generally granulated by wet granulation and extrusion granulation. Extrusion granulation is granulated by an extruder, which is fast and has a relatively uniform particle size, but irregular in shape. After granulation, the raw materials are not tightly bonded, which will cause the raw materials to break before calcination. When wet granulation is used, The granulation is carried out by a granulator, and water mist is sprayed into the granulator through a water spray atomizer to moisten the raw material powder in the granulator, and then the raw material powder is rolled into granules through the rotation of the granulator. After granulation, the shape is uniform and tightly bonded, and no cracking will occur. However, most of the existing water spray atomizers are fixedly installed, and the atomizing nozzle cannot be adjusted. When there is less raw material in the granulator, water mist will be sprayed onto the inner wall of the granulator, and the raw material powder will be locally dry and wet due to the uneven spraying of water mist, thereby resulting in unstable quality of the semi-finished ceramsite sand. In addition, only moistening the raw material with water mist will also lead to slow early forming of the raw material and low efficiency.

[0003] And in the application document with publication number CN214159516U, an improved water spray atomizer is mentioned. The atomizer can be installed in the granulator through a fixing rod. The bottom of the fixing rod passes through the granulator and is fixed to the frame of the granulator, and the water inlet pipe is connected to the external pump. After the driving motor is started, the connecting rod is driven by the meshing cooperation between the driving wheel and the ring rail, and under the action of the first bearing, the sealing fixing seat can rotate on the fixing rod, thereby enabling the atomizing base to rotate, and the water inlet pipe can rotate with the atomizing base under the action of the second bearing. The pump pumps water into the chamber of the inner disc through the water inlet pipe. When the atomizing base disc rotates, it can spray water mist evenly on the raw material powder in the granulator through the atomizing nozzle, so that the raw material powder is moistened and the air humidity in the granulator is guaranteed. At the same time, the atomizing nozzle is arranged on the outer peripheral side of the atomizing base disc. When spraying the raw material powder, the water mist will not be sprayed on the inner wall of the granulator, and the raw material powder will not be locally dry and wet due to uneven spraying of water mist, thereby causing the quality of the ceramsite sand semi-finished product to be unstable. In addition, the sleeve rod can be retracted in the fixed sleeve to drive the atomization. The nozzle moves and can be telescopically adjusted according to the amount of raw material powder in the granulator. When the raw material powder is large, the sleeve rod can be retracted into the fixed sleeve, so that the atomizing nozzle is away from the raw material powder, avoiding the situation that the raw material powder has a high degree of wetness due to the atomizing nozzle being close to the raw material powder; when the raw material powder is small, the sleeve rod can extend out of the fixed sleeve to spray the raw material powder with water mist, avoiding the situation that the raw material powder has insufficient wetness due to the atomizing nozzle being far away from the raw material powder. At the same time, the water in the inner disk can drip out from the dripping hole on the dripping pipe, which can avoid the raw material powder in In the case of low initial forming efficiency, water drops dripping from the dripping hole fall on the raw material powder, which can make the raw material powder quickly bonded, and with the cooperation of the water mist sprayed from the atomizing nozzle, the speed of raw material powder granulation in the early stage is accelerated, the production efficiency of the expanded clay sand semi-finished product is improved, and time cost is saved. In addition, under the action of the sealing part, the dripping hole can be sealed according to production needs, and it is flexible to use, but there are still certain defects that need to be optimized. The specific defects are as follows: the existing device cannot set the drainage content according to the amount of raw material powder. Utility Model Content
