Embodiment Construction

[0026] Attached below figure 1 And specific examples further illustrate the content of the present invention.

[0027] like figure 1 As shown, the present invention is mainly made up of screw shaft 1, throat pipe 2, thrust valve 4, T-shaped pipe 5, pneumatic cylinder 6, surge tank 7, gas source stabilizer 8 and frequency conversion transmission motor 9. The throat is equipped with a pressure sensor, and the pressure regulator tank is equipped with accessories such as an air pressure indicator. The pressure sensor and the frequency conversion motor of the present invention are interlocked and connected to the automatic control system, and can perform stepless speed regulation on the main shaft according to pressure changes and output requirements.

[0028] When working: the screw shaft rotates towards the set direction at a certain speed, and the raw material is pushed from the continuous feeder to the T-shaped pipe to generate thrust F1; a thrust valve core on the T-shaped p...

Abstract

The invention discloses a continuous cooking anti-reverse spraying device. The device mainly comprises a frequency-variable transmission system, a feeding spiral shaft, a throat pipe, a push-stopping valve, a pressure-stabilizing tank and an air source stabilizer. The device is mainly characterized in that: the rotation speed of the feeding spiral shaft can be automatically adjusted according to the flow change of materials, so a pushing force is kept stable. The working pressure of an air source is not affected by external environment and is kept constant through the air source stabilizer, so that 'material plug' is not damaged by the fluctuation of flow pressure in a feeding process, and the aim of preventing reverse spraying in a continuous cooking and feeding process is fulfilled.

Description

technical field [0001] The invention relates to an anti-spraying device for continuous cooking, which belongs to supporting equipment for pulping and cooking, and is used for preventing back-spraying of a continuous feeder. Background technique [0002] In the process of pulping and papermaking, the difference between continuous cooking and batch cooking is that continuous feeding needs to be realized under higher working pressure (0.7-0.8MPa). Since the flow rate of reed flakes cannot be very stable due to various reasons, it is often fluctuating. Therefore, the problem of continuous cooking feeder back injection (material and high-pressure steam rushing out from the feeding port) is common, which seriously affects production safety and causes resource loss. The anti-spray at the feeding port of the continuous digester has always been a thorny issue. The continuous digester uses a special continuous feeder and T-shaped tube for feeding. During use, backspray often occurs du...
