Description

TECHNICAL FIELD

[0001] The utility model relates to double -cone mixing dryer technical field more specifically, it relates to a double -cone mixing dryer with safe anti -misoperation system. BACKGROUND

[0002] Double -cone mixing dryer is a kind of advanced equipment with mixing and drying function in one, is widely used in pharmaceutical, chemical, food and other industries, and its operation safety is directly related to production efficiency and product quality. Its working principle is that after feeding material into double -cone tank, the material is handled by the way of rotary mixing or rotary drying. After mixing or drying is completed, double -cone mixing dryer needs to be discharged to discharge the handled material from the tank. Discharge operation usually involves rotating double cone to a vertical downward position, facilitating discharge. In order to ensure the smooth discharge, double cone and material collecting device are usually connected by butt joint discharge pipe to form a smooth material channel. The two ends of discharge pipe are usually equipped with valves (the discharge pipe mentioned in the specification includes the valves on the upper and lower ends) to facilitate the flow of material. When discharge operation is not needed, the valves will be closed, and the discharge pipe will be disassembled and stored in the fixed point beside for standby. Discharge process may exist, and operation accidents may occur due to poor communication or weak safety awareness of employees. For example, when double -cone mixing dryer is clearly marked "forbidden" and is performing discharge operation, the operator starts the power supply arbitrarily, causing the double cone to rotate suddenly. The strong rotating force instantaneously breaks the fragile discharge pipe, causing material to splash and pollute the site, and the strong traction force also damages the material collecting device below, causing unnecessary economic loss. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a double -cone mixing dryer with safe anti -misoperation system. The utility model eliminates the accidents of broken discharge pipe, spilled material and deformed material collecting device caused by operator's misoperation, and improves the safety of the whole mixing and drying device.

[0004] The specific technical solutions are as follows:

[0005] The utility model provides a double -cone mixing dryer with safe anti -misoperation system, including frame, the double -cone cylinder rotatably arranged on the frame, the motor of driving the cylinder rotation is arranged on the frame still includes the hose of discharging, the material collecting device, the controller, the electromagnetic main contactor, the relay of always open state, infrared emitter and infrared receiver, the frame is vertically arranged, the cylinder is rotatably arranged on the frame through horizontal pivot, the cylinder is positioned vertically, the hose of discharging connects the lower port of the cylinder with the material collecting device, and completes the discharging operation, when the cylinder mixes material, the lower port of the cylinder is disconnected with the hose of discharging, the electromagnetic main contactor is connected in series in the power supply line of motor, and keeps always open state, infrared emitter and infrared receiver are oppositely arranged in the lower part of frame, and infrared receiver is connected through secondary circuit controller, relay and the electromagnetic main contactor, when the cylinder discharges, the infrared ray of infrared emitter is blocked by the discharging pipe, and the relay, electromagnetic main contactor all keep off, when the hose of discharging is separated from the lower port of the cylinder, infrared receiver receives infrared signal, and the relay, electromagnetic main contactor all close.

[0006] The double -cone mixing dryer with safe anti -misoperation system further designs the shielding fin on the outer wall of the hose of discharging.

[0007] Technical effects:

[0008] When infrared receiver does not receive the light signal of emitter, that is, the discharging pipe is connected between the double -cone discharging pipe and the material collecting device, any misoperation of operator can not start the power supply of double -cone, prevents the discharging pipe from being pulled apart, material from being scattered and the material collecting device from being pulled and deformed, and improves the safety of the whole mixing drying device.

[0012] The utility model is further explained as follows in combination with the drawings and examples of the specification:

[0013] A double-cone mixing dryer with a safe anti-misoperation system, as shown in the figure, comprises a frame, a double-cone cylinder 7 rotatably arranged on the frame, a motor 4 arranged on the frame to drive the cylinder to rotate, a feeding hose 8, a material collecting device 9, a controller 1, an electromagnetic main contactor 2, a normally open relay 3, an infrared emitter 5 and an infrared receiver 6. The frame is vertically arranged, and the cylinder is rotatably arranged on the frame through a horizontal rotating shaft. When the cylinder is vertically positioned, the feeding hose 8 is connected to the lower end port of the cylinder and the material collecting device to complete the feeding operation. When the cylinder is mixing, the lower end port of the cylinder is disconnected from the feeding hose. The electromagnetic main contactor is connected in series in the power supply circuit of the motor and is kept in a normally open state. The infrared emitter and the infrared receiver are oppositely arranged at the lower part of the frame, and the infrared receiver is connected to the controller, the relay and the electromagnetic main contactor through a secondary circuit. When the cylinder is feeding, the infrared emitted by the infrared emitter is blocked by the feeding hose, and the relay and the electromagnetic main contactor are both kept open. When the feeding hose is disconnected from the lower end port of the cylinder, the infrared receiver receives the infrared signal, and the relay and the electromagnetic main contactor are both closed.

[0014] When not feeding, the feeding hose falls, and the infrared receiver can receive the signal emitted by the infrared emitter. The infrared receiver transmits the signal to the secondary circuit relay, the normally open contact of the relay is closed, the electromagnetic main contactor is connected, and the motor of the double-cone mixing dryer can be started.

[0015] When feeding, the infrared receiver cannot receive the signal emitted by the infrared emitter, the infrared receiver transmits the signal to the controller and the normally open contact of the relay is opened, the secondary circuit relay is disconnected, the electromagnetic main contactor is disconnected, and the motor of the double-cone mixing dryer cannot be started.

[0016] Since the feeding hose may not be accurately positioned between the infrared emitter and the infrared receiver, it is necessary to adjust the positions of the infrared emitter and the infrared receiver. However, even so, the feeding hose may still deviate due to vibration during the feeding process. Therefore, in order to ensure the blocking effect of the feeding hose on the infrared, a shielding fin 81 is arranged on the outer wall of the feeding hose.
