Problems solved by technology

Its sealing effect depends on the tight fit between the rotor and the cylinder, but during long-term operation, the rotor blades are worn by the material and the sealing performance becomes poor, so they need to be replaced in time, so the star-shaped ash discharge machine is not suitable for dolomite, magnesia abrasive materials

Embodiment Construction

[0026] The structure and use method of a sealed unloading device will be described in detail below through specific embodiments.

[0027] See figure 1 , figure 2 , image 3 , a sealed unloading device, including a discharge spout door 1, a box body 2, a cover plate 3, an oil cylinder 4, a bearing with a seat 5, a counterweight rod 6, a protective cover 7, a sealing ring 8, a single rotating door 9, The isolation seat 10 and the integral bearing are arranged on the outside of the box body 2 and are isolated with the isolation seat 10 between the box body, and the isolation seat 10 is provided with a dust discharge channel 15 . This structure allows the leaked dust to be discharged through this channel without entering into the bearing. A labyrinth sealing structure and a sealing ring are adopted between the isolation seat 10 and the rotating shaft. A silicone rubber sealing ring 8 is provided at the contact portion between the blanking spout door 1 and the box body 2 . An...

Abstract

The invention relates to a using method of a closed-type discharging device. The device comprises a discharging sprout door, a bearing and a box body, wherein the bearing is arranged outside the box body and is separated from the box body by a separating seat provided with a dust discharging channel. The discharging process is accomplished by two discharging gates and a middle translational section, a material falls into the discharging gate I through a receiving port and then enters into the translational section after the discharging sprout door of the discharging gate I is opened via a hydraulic oil cylinder, afterwards, the discharging sprout door of the discharging gate I is closed and the discharging gate II is opened, the material in the translational section enters into the discharging gate II and is delivered to a belt conveyor via a vibrating feeder, the discharging gate II is closed and then the discharging sprout door of the discharging gate I is opened, followed by the circulation of the above steps. The external leakage of the air in kiln can be effectively prevented through the cooperative use of the device and the two discharging gates.

Description

technical field [0001] The invention relates to a method for using a discharge device, in particular to a method for using a sealed discharge device with a new structure used to prevent air leakage in the kiln during the discharge process of a lime shaft kiln. Background technique [0002] Since the 1970s, there have been two basic types of unloading sealing devices. One type is a shaft kiln that can only be used to stop the wind and discharge materials. This type of device has a single-layer valve and a double-layer valve device. The other type is a device that can discharge materials from the hopper under the condition of non-stop wind. This type of device has three gates, a star-shaped ash discharge machine, and so on. [0003] The single-layer sealing valve device is composed of the single-layer valve and the electric vibration feeder for interception and discharge, and the sealing valve is used for sealing the discharge chute of the electric vibration feeder. The advan...
