Description

Technical Field

[0001] The utility model relates to the technical field of feeding and crushing equipment, in particular to an automatic feeding and crushing conveying chain system. Background Art

[0002] The crushed material of this equipment is synthesized in a reactor by cassava starch, caustic soda flakes, propylene oxide, etc. The reactor is heated by the steam generated by the steam boiler. When the temperature reaches a certain level, the gas supply is stopped. Then the etherification reaction is carried out for a certain period of time, and finally the material is cooled down and discharged. Sometimes due to unstable steam pressure (pressure is proportional to temperature), the reactor may heat up too quickly due to excessive pressure or uneven stirring in the reactor, causing some materials to agglomerate and have too high hardness, forming hard particles when crushed. When the crusher cavity receives such materials, it is difficult to crush them in the same time, and the induced draft fan cannot suck them out, but the material conveyor continues to feed them in. This will cause the turntable in the crusher to be blocked due to excessive materials in the cavity, and the motor current will increase, causing the control inverter of the crusher to stop due to current overload. Utility Model Content

[0003] In view of the above problems, the utility model provides an automatic feeding, crushing and conveying interlocking system, which solves the problem of excessively high motor current caused by obstruction of materials in the crusher cavity.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an automatic feeding, crushing and conveying chain system, including a controller, a power module, a power control module, a feeding module, a cyclone module, a crushing module and an induced draft module, the power module is connected with the feeding module, the cyclone module, the crushing module and the induced draft module, the power module supplies power to the feeding module, the cyclone module, the crushing module and the induced draft module through a main line; switch circuit breakers are provided between the power module and the feeding module, the cyclone module, the crushing module and the induced draft module, the power control module includes a feeding frequency converter, a cyclone frequency converter, a crushing frequency converter and an induced draft frequency converter, and are respectively connected with the power module.

[0005] As an optimization, the feeding inverter is provided with an emergency stop normally closed button S1, the cyclone inverter is provided with an emergency stop normally closed button S2, the induced draft inverter is provided with an emergency stop normally closed button S3, and the crushing inverter is provided with normally open contacts TA and TC. The emergency stop normally closed button S1, the emergency stop normally closed button S2, the emergency stop normally closed button S3 and the common terminal COM of the inverter and the normally open contacts TA and TC are connected in series to form a fault interlocking circuit.

[0006] As an optimization, the feeding module includes a feeder, the cyclone module includes a cyclone, the crushing module includes a crusher, and the induced draft module includes an induced draft fan.

[0007] The beneficial effect of the utility model is as follows: the utility model provides an automatic feeding, crushing and conveying interlocking system. After the related equipment of the crushing machine group is interlocked, when there is too much material in the crusher cavity, the motor current rises to a certain value (a pre-alarm value is set before the alarm shutdown, such as: the shutdown current is 100%, and the pre-alarm value is set to 90%). When the pre-alarm value is reached, the output terminal of the crusher inverter simultaneously transmits a signal to the input terminal of the conveyor, cyclone, and induced draft fan inverter, so that the conveyor and cyclone are shut down (the cyclone prohibits coarse materials from leaving the crusher cavity), and the induced draft fan speed is accelerated to the upper limit, so as to quickly extract the difficult-to-crush materials in the cavity and reach the next process vibrating screen coarse material receiver for recovery. When the material in the cavity is cleared and the current drops to 70% of the rated current, the related equipment resumes normal operation, thereby achieving the purpose of automatic interlocking operation, which not only improves work efficiency, but also ensures product quality, and reduces the damage rate of equipment.

[0016] The normally open contacts TA and TC of the crushing inverter are the overload pre-alarm output signals, and the parameter setting P602 is set to 10 (the maximum current value allowed for the motor operation).

[0017] The emergency stop normally closed button S1 of the feeding inverter receives the pre-alarm signal, the motor operation is suspended, and normal operation is resumed after the alarm is lifted. The parameter setting P501 is set to 8.

[0020] Working principle: The utility model provides an automatic feeding, crushing and conveying interlocking system. When the material in the crusher cavity is blocked (material is uneven), the motor current will increase. When the inverter controlling the motor receives the high current upper limit pre-alarm signal, it transmits a pause signal to the feeder and cyclone inverter through the input terminal, commanding it to stop running. The material in the crusher cavity is drawn out by the induced draft fan and enters the coarse material trough. When the crusher current drops to the allowable current starting value, the feeder cyclone starts automatically, and the crusher unit resumes operation.
