Description

Simple hot-state spray repair device for coke oven

Technical Field

The utility model relates to the technical field of coke oven maintenance, in particular to a simple hot spray repair device for a coke oven.

Background

The coke oven is a core device for coking production and is built by refractory materials with various specifications, and the building body is protected and restricted by different types of oven protection devices to ensure that the building body expands according to the design so as to ensure the safety, environmental protection and smooth operation of the coke oven. Due to the production characteristics of the coke oven, the oven door at the coke side of the coke oven needs to be periodically opened and closed, and the inside of the carbonization chamber also needs to periodically push out the mature high-temperature coke and load the low-temperature blended coal to be refined, so that the oven wall of the coke oven is periodically heated and cooled. If the fire is not adjusted and the temperature is controlled in time, the water content of the matched coal is high, and a large iron device or production equipment rubs and touches the furnace wall, the furnace wall can be expanded, degraded, damaged and perforated in an over-design level, so that the environmental protection events such as furnace body leakage, chimney smoke and the like are caused, production interruption accidents are caused, and the smooth operation of production is restricted.

At present, the method for remedying the blowby of the wall of the coke oven mainly comprises the centralized processes of wet method, semi-dry method spray repair, ceramic welding repair, ceramic spraying and the like. Wherein, the wet gunning has been gradually eliminated because of high water content and great damage to high temperature furnace body. The ceramic welding and spray repair is not widely popularized due to high cost and long construction time. The semi-dry gunning reduces the water content of the gunning material, is convenient to construct, consumes short time, becomes a generally adopted renovation process of each coking enterprise, and has the following problems: the spray repair equipment has a complex structure, a large volume and inconvenient movement; there are more associated auxiliary ducts.

Disclosure of Invention

The utility model aims at solving the problems of the prior gunning device and providing a simple hot gunning device of a coke oven, which has simple structure and convenient use.

The utility model discloses a concrete scheme is: the utility model provides a simple and easy coke oven hot spray repair device, including a material jar, the material jar top is equipped with the inlet pipe, the feed valve is equipped with on the inlet pipe, the inlet pipe upper end is connected to the container that is equipped with the gunning material in advance, the material jar lower extreme is equipped with the blowing pipe, the blowing valve is equipped with on the blowing pipe, the four-way pipe is equipped with to the blowing pipe bottom, the four-way pipe left end is connected with compressed air pipe, compressed air pipe is connected to compressed air source, the blowing pipe is connected to the four-way pipe upper end, the four-way pipe right-hand member is connected with ejection of compact hose, the detachable spray gun is equipped with to ejection of compact hose outer end, the four-way pipe lower extreme is equipped with row cinder notch.

Material jar upper end is equipped with the pressure release pipe, and manometer and relief valve are equipped with to the outer end of pressure release pipe.

Material jar upper end is equipped with cleans the pipe, cleans and is equipped with the valve on the pipe, cleans the outside of tubes end and is connected to compressed air source.

The upper end of the inlet pipe is provided with a cone hopper, and the top end of the cone hopper is connected to a container provided with premixed gunning material.

The working principle of the utility model is as follows: the spraying material is uniformly mixed in the container pre-filled with the spraying material, after the uniformly mixed material is loaded into the charging bucket, the opening degree of a feeding hole is kept, the spraying material can continuously flow to a discharging pipe due to the self gravity effect of the spraying material, and the compressed air from a compressed air pipe can push the uniformly mixed material to move towards a spray gun so as to realize the spraying work; after the weight of the blending material is reduced and the blending material is not enough to continuously descend, the gunning can be stopped, the blending gunning material is continuously added into the charging bucket, the feeding hole can also be closed, the valve of the cleaning pipe is opened, and the positive pressure state in the storage bin is kept.

The utility model discloses following beneficial effect has: on one hand, the structure is simple, the flexibility of equipment movement is improved, and the convenience of spray repair use is enhanced; on the other hand, the quantity of the rebound materials in the spray repair work is reduced, the spray repair efficiency is improved, and the thermal state maintenance cost is reduced.
