Description

TECHNICAL FIELD

[0001] The application relates to the technical field of a granulating nozzle, in particular to a high-speed granulating nozzle. BACKGROUND

[0002] During granulation, a granulating nozzle is usually used to spray liquid, and the granulating nozzle needs to rotate at a high speed.

[0003] Generally, a motor with a high rotating speed can be used to keep the granulating nozzle rotating at a high speed. However, during actual granulation, on the one hand, the temperature inside the granulating device is relatively high, while the temperature outside the device is relatively low, so that the temperature difference between the inside and outside of the shaft is large, and on the other hand, bearings and other components are usually arranged between the shaft and the shell to maintain rotation, and heat is generated during high-speed rotation. The large temperature difference causes the bearings and other components to bear a large working pressure, and finally the granulating nozzle cannot rotate at a high speed.

[0004] The existing solution is to additionally arrange a cooling device to cool the components through a circulating water channel, so as to meet the requirement of high-speed rotation of the nozzle. However, this solution has a high cost, and once the cooling water leaks, the granulation process will be polluted. CONTENT OF THE INVENTION

The shaft body is rotatably arranged on the shell, the motor drives the shaft body to rotate, one end of the shaft body receives liquid, and the other end of the shaft body is used for discharging liquid. The cooling disc is arranged in the shell, and the cooling disc is located outside the shaft body and is in abutment with the shaft body to receive the liquid in the shaft body. The liquid flows in the cooling disc to take away heat.

[0007] Preferably, the shaft body comprises an upper part and a lower part, one end of the upper part is connected with a rotary joint, the other end of the upper part is provided with a plurality of liquid outlets, one end of the lower part is provided with a plurality of liquid inlets, and the other end of the lower part is provided with a plurality of liquid spraying ports.

[0008] Preferably, the plurality of liquid outlets and the plurality of liquid inlets are distributed in the circumferential direction.

[0009] Preferably, a flow channel is designed in the cooling disc, the flow channel has a liquid inlet channel and a liquid outlet channel, the liquid inlet channel is in abutment with the liquid outlet, and the liquid outlet channel is in abutment with the liquid inlet.

[0010] Preferably, the liquid inlet channel and the liquid outlet channel are both trumpet mouths, and the number of the liquid inlet channels and the liquid outlet channels is multiple.

[0011] Preferably, the cooling disc is provided with a first annular channel and a second annular channel, the first annular channel and the second annular channel are connected through multiple connecting channels, the first annular channel is further connected with the liquid inlet channel, and the second annular channel is further connected with the liquid outlet channel.

[0012] Preferably, the output end of the motor is provided with a driving wheel, and the shaft body is provided with a driven wheel, and the driving wheel and the driven wheel are connected through a synchronous belt.

[0013] In summary, the present application has the following beneficial effects:

The present application does not need to additionally set a cooling device, and the manufacturing and using costs are low. If leakage occurs, the liquid to be granulated is the same as the product ingredients, avoiding a great impact caused by using other cooling liquids. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be described in detail in combination with the accompanying drawings. Figures 1-4 The present application will be further described in detail.

[0021] Wherein the same parts are denoted by the same reference signs.

[0022] The application discloses a high-speed granulation nozzle, which comprises a motor 1, a shaft body 2 and a cooling disc 31, the shaft body 2 is rotatably installed on a shell 3, the motor 1 drives the shaft body 2 to rotate, one end of the shaft body 2 receives liquid, and the other end of the shaft body 2 is used for discharging liquid; the cooling disc 31 is installed in the interior of the shell 3, the cooling disc 31 is located outside the shaft body 2, the cooling disc 31 is opposite to the shaft body 2 to receive the liquid in the shaft body 2, and the liquid flows in the cooling disc 31 to take away heat.

[0023] That is to say, the bearing and other components between the shaft body 2 and the shell 3 are affected by the lower temperature outside and the higher temperature inside, the cooling disc 31 is arranged on the side close to the bearing in the interior of the shell 3, part of heat is taken away by using the flow channel of the granulation liquid itself, the temperature inside and outside the bearing and other components tends to be consistent, and then the rotating effect of the shaft body 2 is guaranteed, so that the shaft body can keep high-speed rotation.

[0024] Specifically, the shaft body 2 comprises an upper part and a lower part, one end of the upper part is connected with a rotary joint 4, a plurality of liquid outlets 21 are arranged at the other end of the upper part, a plurality of liquid inlets 22 are arranged at one end of the lower part, and a plurality of liquid spraying ports are arranged at the other end of the lower part. The plurality of liquid outlets 21 and the plurality of liquid inlets 22 are distributed in the circumferential direction. Moreover, a flow channel is designed in the cooling disc 31, the flow channel has a liquid inlet passage 311 and a liquid outlet passage 313, the liquid inlet passage 311 is opposite to the liquid outlet 21, and the liquid outlet passage 313 is opposite to the liquid inlet 22.

[0025] That is to say, the upper part and the lower part of the shaft body 2 are not directly communicated, but are opposite to the liquid inlet passage 311 and the liquid outlet passage 313 of the cooling disc 31 respectively, so that the entering liquid first flows through the cooling disc 31 and then is sprayed in the interior of the granulation device.

[0026] In the embodiment, the cooling disc 31 is a circular ring, and a rotary sealing piece is arranged between the cooling disc 31 and the shaft body 2, so that liquid leakage is avoided.

[0027] Preferably, the liquid inlet passage 311 and the liquid outlet passage 313 are both trumpet mouths, and the number of the liquid inlet passage 311 and the liquid outlet passage 313 is plural.

[0029] The design of the two-layer annular channels can ensure the residence time of the liquid in the cooling disc 31 and guarantee the heat exchange effect.
