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 new type of sealed unloading device will be described in detail below through specific embodiments.

[0027] See figure 1 , figure 2 , image 3 , a sealed unloading device with a new structure, 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 rotating unit The 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 sp...

Abstract

The invention relates to a discharging device and application thereof, and particularly to a sealing type discharging device with a novel structure which is used to prevent air leakage of a kiln in the discharging process of a lime shaft kiln. The device comprises a discharging sprout door, a bearing and a box body, wherein the bearing is arranged outside the box body and separated from the box body by a separating seat provided with a dust discharging channel; a maze type sealing structure and a sealing ring are utilized between the separating seat of the box body and a rotating shaft; the contacting part between the discharging sprout door and the box body is provided with a sealing ring; and the device is arranged on a material receiving opening below a discharging machine of the lime shaft kiln to prevent the air leakage of the kiln, and has the advantages of having good sealing effect, discharging materials without stopping wind and having the action of stopping flow, along with simple structure, light weight and few easily-damaged parts.

Description

technical field [0001] The invention relates to an unloading device and its application, in particular to a sealed unloading device with a new structure used to prevent air leakage in the kiln during the unloading 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 advantage of this devi...
