Detailed Description
Example 1
As shown in figure 1, an integrated preparation kiln for inorganic powder and products comprises a base 2 and a kiln body 1 rotationally connected with the base 2, wherein a driving device for driving the kiln body 1 to rotate is arranged between the base 2 and the kiln body 1. The kiln body 1 is obliquely arranged in a mode of being high on the left and low on the right or horizontally arranged, and the material axial conveying is realized by using a conveying plate in the kiln body. Preferably, when the kiln body is obliquely arranged, the included angle between the axis of the kiln body 1 and the horizontal plane is 2-8 degrees.
As a specific embodiment, as shown in fig. 1, at least two belts 11 are disposed on the kiln body 1, two supporting wheels 21 for supporting the kiln body 1 are symmetrically disposed below each belt 11 on the base 2, and the belts 11 are pressed on the supporting wheels 21. The driving device comprises a motor 31, a speed reducer 32, a driving wheel 33 and a driven wheel 34. An output shaft of the speed reducer 32 is connected to the driving wheel 33, and a driven wheel 34 engaged with the driving wheel 33 is provided on the kiln body 1.
As shown in figure 1, a kiln head cover 4, a discharging cover 5, a blast cover 6 and a kiln tail cover 7 are sequentially arranged on the kiln body 1 from left to right, and the kiln head cover 4, the discharging cover 5, the blast cover 6 and the kiln tail cover 7 are respectively and hermetically connected with the kiln body 1. The kiln head cover 4, the discharging cover 5, the blast cover 6, the kiln tail cover 7 and the kiln body 1 form a closed space together.
Since in the conventional rotary kiln, a sealing type connection structure exists between the kiln head cover 4, the kiln tail cover 7 and the kiln body 1. Therefore, the sealing structure between the discharging hood 5, the blowing hood 6 and the kiln body 1 only needs to adopt the sealing mechanism between the traditional kiln hood 4, the kiln tail hood 7 and the kiln body 1, which belongs to the prior art and is not described herein.
The kiln is characterized in that a feed hopper 41 is arranged on the outer side face of the kiln head cover 4, a guide chute 42 is arranged on the feed hopper 41, the guide chute 42 is arranged in a downward inclined mode, and the guide chute 42 extends into the kiln body 1.
An air outlet 43 is arranged on the upper side of the kiln head cover 4, and the air outlet 43 is connected with an induced draft fan through a pipeline. The air blowing cover 6 is provided with an air inlet 61, and the air inlet 61 is connected with the first air blower through a pipeline. As shown in fig. 2, an air inlet hole 13 is arranged on the kiln body 1 and positioned in the air blowing cover 6. Preferably, the number of the air inlets 13 is plural, and the air inlets are uniformly distributed along the circumferential direction.
This is mainly set for two reasons: first, during operation, the induced draft fan is induced by the induced draft opening 43, and the air blower blows air through the air inlet 61, so that the air flow in the kiln flows along the axis of the kiln body 1 from right to left, and the air flow and the burner 81 cooperate to realize the control of the temperature field in the kiln. Secondly, when the sintered inorganic product enters the cooling area surrounded by the blast cover 6 from the sintering area of the kiln body 1, the inorganic product can be uniformly cooled by blowing cold air into the kiln body 1. The initially cooled mineral product continues to move to the right along the kiln body 1 axis and finally is discharged through the second discharge opening 71 of the kiln tail hood 7. Is beneficial to realizing mechanical and automatic operation.
As shown in fig. 1 and fig. 2, the discharge cover 5 is provided with a first discharge opening 51, a plurality of blanking holes 12 are formed in the kiln body 1 and located in the discharge cover 5, and the blanking holes 12 are uniformly distributed along the circumferential direction.
Thus, when the calcined inorganic powder and the sintered inorganic product pass through the kiln body 1 surrounded by the discharge hood 5, the inorganic powder enters the discharge hood 5 through the blanking hole 12 on the wall of the kiln body and finally is discharged through the first discharge opening 51 at the lower end of the discharge hood 5, and the sintered inorganic product continues to move rightward along the axis of the kiln body 1.
Further, in order to thoroughly discharge the calcined inorganic powder from the kiln body 1, it is avoided that the inorganic powder is mixed in the finally obtained inorganic product, and as shown in fig. 2, a plurality of rows of blanking holes 12 are axially arranged on the kiln body 1 in the discharge cover 5. As a specific embodiment, 3 rows of blanking holes 12 are axially arranged on the kiln body 1 in the discharging cover 5 in the embodiment.
The blanking holes 12 may not be arranged in rows, and may be arranged in a staggered manner, so long as they are distributed in a certain width region of the kiln body 1 along the axial direction. Preferably, the width of the distribution area is 300-400mm.
Further, in order to facilitate the discharge of the inorganic powder from the first discharge port 51, as shown in fig. 3, a guide hopper 52 is provided at the upper end of the first discharge port 51.
As shown in fig. 1 and 2, the combustion assembly includes a burner 81 disposed on the kiln tail hood 7, and an extension pipe 82 is fixedly disposed on a nozzle of the burner 81, and a suspension end of the extension pipe 82 passes through the blast hood 6, and in this embodiment, the suspension end of the extension pipe 82 extends into the discharge hood 5.
Example two
As shown in fig. 4, the combustion assembly comprises a fuel supply pipe provided on the kiln body 1, and as shown in fig. 6, 7 and 9, the fuel supply pipe comprises a supply section 951, a connection section 952 and a rotation section 953.

The rotating section 953 is disposed in the kiln head cover 4 and is coaxially disposed with the kiln body 1. The left end of the rotary segment 953 is connected to a fuel supply through a rotary joint 96 after passing through the kiln head cap 4. The connection section 952 is disposed inside the kiln body 1 and is located on the right side of the guide chute 42, one end of the connection section 952 is connected to the end of the rotation section 953, and the other end of the connection section 952 penetrates through the side wall of the kiln body 1 and then is connected to the end of the supply section 951. Preferably, the connection segments 952 are radially disposed.
The structure of the rotary joint 96 is known in the art and will not be described in detail herein.
As shown in fig. 4, a plurality of groups of burners are axially arranged on the outer side wall of the kiln body 1 between the kiln head cover 4 and the discharge cover 5, and as a specific embodiment, four groups of burners are arranged on the outer side wall of the kiln body 1 in this embodiment.

The air inlet of the burner 91 is connected to a second blower 93.
The burner may also be an integrated burner. However, as a preferred embodiment, the burner described in this embodiment adopts a combined structure, mainly because the burner rotates together with the kiln body 1 during operation, so that the smaller the burner volume, the better. If an integrated burner is used, the turning radius is large, and the size of other components needs to be adaptively adjusted according to the size of the burner, for example, the height of the base 2 is increased, which increases the structural size of the whole device.
Further, in order to prevent the burner 91 from being blocked by the inorganic powder or the inorganic product in the kiln body 1 during operation, and to ensure the normal operation of the burner, as shown in fig. 8, the burner block provided on the side wall of the kiln body 1 is higher than the inner side wall of the kiln body 1. The burner block and its mounting structure described herein belong to the prior art and are also applicable to conventional kilns and will not be described in detail herein.
The rest of the structure is the same as that of the first embodiment.
Example III
