The machine is mainly composed of transmission system, two inclined stirring shafts, cross arms, cylinder, discharge valve and the like. Two working screws are parallel to the generatrix of the conical cylinder, symmetrically distributed on both sides of the center line of the cone, and intersect at the bottom of the cone, connected with the center pull rod. The upper parts of the two stirring shafts are connected with the cross arms extending from the center to both sides respectively, forming a mechanically symmetrical and balanced inverted triangular structure.
[0003] The stirring shafts will revolve and rotate during stirring and back-pumping. The revolution of the stirring shaft is driven by the upper cross arm by the revolution motor, and the rotation of the stirring shaft is driven by the transmission system by the rotation motor.

However, during the stirring process, the sprayed additives will be sprayed onto the cross arm, causing waste of additives, uneven spraying of liquid and affecting product performance. Moreover, during the back-pumping process, particles will accumulate on the cross arm, causing uneven mixing of additive particles and affecting product performance. CONTENT OF THE UTILITY MODEL
[0005] The utility model aims to provide a mixing kettle with photoelectric induction device, which solves the problem of attachment of additives and particles on the cross arm during spraying and back-pumping.

The control device is connected with the photoelectric induction device, the liquid spraying device and the blowing device. The photoelectric induction device is arranged on the cover plate. When the cross arm rotates to below the photoelectric induction device, the control device controls the liquid spraying device to pause spraying and controls the blowing device to start blowing.
[0007] Preferably, the blowing device is provided with a plurality of blowing nozzles along the radial direction of the cover plate.
[0008] Preferably, the photoelectric induction device is a photoelectric sensor.
[0009] Preferably, the blowing device is a blowing nozzle, and the blowing nozzle is connected with a positive pressure gas source.

[0011] Preferably, a first hopper and a second hopper are arranged at the bottom of the barrel, and the first hopper and the second hopper are connected to the barrel through a first feeding pipe and a second feeding pipe, respectively.
[0012] In summary, the present application has the following advantages:
[0013] When the cross arm rotates to below the photoelectric sensing device, the photoelectric sensing device senses the position of the cross arm and transmits a signal to the control device, and the control device controls the liquid spraying device to pause spraying, so as to avoid the cross arm being sprayed with the auxiliary agent when passing through the liquid spraying port, avoid waste of the auxiliary agent and uneven spraying, and improve product performance; meanwhile, the controller also controls the air blowing device to start blowing, and when the cross arm passes below the air blowing device, the air blowing device blows the upper surface of the cross arm to blow off the particles accumulated on the cross arm during back suction, so that the mixing of the particles is more uniform, which helps to improve product performance.

[0021] Embodiment:
[0022] As Figure 1 - Figure 4 shown, the mixing kettle in the embodiment includes a conical cylinder 1, which is provided with a cross arm 11 and stirring shafts 12. The number of stirring shafts 12 is three, which are respectively connected to both ends of the cross arm 11 and the middle of the cross arm 11. The stirring shafts 12 at both ends of the cross arm 11 are arranged along the side of the cylinder 1, and the stirring shaft 12 in the middle of the cross arm 11 is arranged vertically. A cover plate 13 is arranged at the top of the cylinder 1, and the cover plate 13 is provided with a revolution motor 14 and a rotation motor 15. The revolution motor 14 and the rotation motor 15 drive the stirring shafts 12 to revolve and rotate respectively through a transmission system.
[0023] The cover plate 13 has a door body 2 and a liquid spraying port 21. The door body 2 is below a feeding port for adding materials to be stirred. The liquid spraying port 21 is used for adding an additive, and a liquid spraying device (not shown in the figure) is connected at the liquid spraying port 21 for spraying the additive towards the inside of the liquid spraying port 21. A plurality of air blowing devices 22 are installed on the cover plate 13 along the radial direction thereof, and the number of air blowing devices 22 is four in the embodiment. The air blowing device 22 is an air blowing nozzle, which is connected with a positive pressure gas source such as an air pump. The air blowing device 22 is arranged downwardly for blowing and purging downwardly. A photoelectric sensing device 23 is also installed on the cover plate 13, which is a photoelectric sensor and is arranged downwardly. When the cross arm 11 passes below the photoelectric sensing device 23, the photoelectric sensing device 23 sends a signal.
[0024] The photoelectric sensing device 23, the liquid spraying device and the air blowing device 22 are connected with a control device. When the cross arm 11 passes below the photoelectric sensing device 23, the control device controls the liquid spraying device to pause spraying and controls the air blowing device 22 to start blowing for a period of time.
[0025] The bottom of the cylinder 1 is provided with a bin 1 24 and a bin 2 25, which are respectively connected with the cylinder 1 through a feeding pipe 1 26 and a feeding pipe 2 27. The feeding pipe 1 26 and the feeding pipe 2 27 are respectively provided with a valve 1 28 and a valve 2 29.
[0026] Method for use:
[0027] As Figure 4As shown, the cross arm 11 rotates clockwise in the figure, and first passes under the photoelectric sensing device 23 when rotating. The photoelectric sensing device 23 senses the passage of the cross arm 11 and sends an electrical signal to the control device. The control device controls the liquid spraying device to pause the liquid spraying and the air blowing device 22 to start blowing. When the cross arm 11 leaves the bottom of the liquid spraying port 21, the liquid spraying device resumes the liquid spraying; when the cross arm 11 leaves the bottom of the air blowing device 22, the air blowing device 22 stops blowing. It should be noted that the positions of the photoelectric sensing device 23, the liquid spraying port 21, and the air blowing device 22 on the cover plate 13 are arranged in sequence along the rotation direction of the cross arm 11, so that when the cross arm 11 rotates, it passes through the photoelectric sensing device 23, the liquid spraying port 21 and the air blowing device 22 in sequence. The duration of the suspension of the liquid spraying and the duration of the blowing are controlled by the timing unit in the control device, which belongs to the existing technology and will not be described in detail.
