Description

A kind of big pipeline gas flow switch

Technical field

The utility model is related to Fan Equipment field, more particularly to a kind of big pipeline gas flow switch.

Background technology

In STEELMAKING PRODUCTION, if too high oxygen level in molten steel can casting when form bubble, make steel ingot generate stomata, The defects of lawsuit, influences the qualification rate of steel, therefore carries out deoxidation work to molten steel to input aluminium slag ball in molten steel before casting, The content for reducing steel water oxygen, improves the qualification rate of steel；Molten steel also requires the moisture of aluminium slag ball simultaneously, if aluminium The problems such as slag ball contains moisture after putting into molten steel, and high temperature can make moisture evaporation equally will produce stomata, therefore in aluminium slag ball It is also required to that work is dried in production process.

The Chinese patent of Publication No. CN2577061Y discloses a kind of pipeline switch, it uses rigid material pipeline Fit structure between switch housing and ceramic ball valve, using the smoothness and abrasion resistance on ceramic ball valve surface, reduce ball valve with Structural friction force between pipe switch shell increases the service life of ball valve, but in the work that aluminium slag ball is dried, is Ensure the drying work to a large amount of aluminium slag balls, then needs bigbore pipeline to blast hot-air into drying box, if using this Class pipe switch controls gas flow size, can not only increase manufacture and buying cost, while high temperature can also be conducted to handle It makes one normally pull handle.

Utility model content

The purpose of this utility model is to provide a kind of big pipeline gas flow switch, has the gas of control large diameter pipeline The advantages of body flow.

The above-mentioned technical purpose of the utility model technical scheme is that：A kind of big pipeline gas stream Amount switch, including babinet, drying equipment, air feed equipment, the air feed equipment connection babinet and drying equipment, the air feed equipment The hot gas generated in drying equipment is brought into babinet, the air feed equipment includes exhaust fan, runner, and the exhaust fan is connected in Drying equipment one end, the runner are rotatably connected between exhaust fan and drying equipment, and several extension bars are hinged on the runner, The extension bar passes through exhaust fan, one end in the extension bar insertion exhaust fan to be fixed with blade.

By using above-mentioned technical proposal, when being passed through hot-air into babinet, extension bar is passed through by turn runner again Transmission makes blade open and close, and the amount of the hot-air of babinet is flowed into using the opening and closing degree control of blade, makes the heat of babinet autophage Amount size is identical as the amount of heat that exhaust fan is pumped into, and the temperature in guard box body maintains the temperature that aluminium slag ball can be made to dry, Exhaust fan can be made to be isolated with drying equipment when babinet reaches drying temperature, so make babinet by residuals temperatures to aluminium slag ball into The energy is saved in row drying.

Further, it is fixed with limited post on the exhaust fan outer wall, position-arresting disk, the limit is fixed on the extension bar Disk is slidably connected with limited post, and fixing bolt is threaded on the limited post.

By using above-mentioned technical proposal, when limited post is in position-arresting disk different location, the bolt that is tightened fixes limit The position of disk reaches regulation blade opening degree, controls the purpose of air mass flow.

Further, the babinet upper end is fixed with several struts, the strut axis horizontal and both ends are connected in babinet On inner wall, the babinet side is equipped with conveyer belt, and coniform sub-material is fixed on the strut immediately below described conveyer belt one end Platform.

By using above-mentioned technical proposal, when aluminium slag ball is transferred to babinet by conveyer belt, by Material distribution platform to aluminium slag ball into Row separation, increases the contact area of aluminium slag ball and hot-air, improves drying efficiency.

Further, the conveyer belt both sides are fixed with corrugated outer protecting band.

By using above-mentioned technical proposal, outer protecting band is set, aluminium slag ball is avoided to be fallen from conveyer belt both sides, while outer protecting band It can freely extend when moving to conveyer belt bending place, avoid the occurrence of the phenomenon that being pulled off.

Further, the conveyer belt upper surface is fixed with several scraping wings, the pusher plate end face and conveyer belt end face Vertical and scraping wings both ends are connected with outer protecting band.

By using above-mentioned technical proposal, setting scraping wings increases the contact area of conveyer belt and aluminium slag ball, and then makes biography Send band that can preferably transport aluminium slag ball.

Further, the babinet bottom end is connected there are four cone mouth, and described larger one end of cone mouth bore is connected with babinet, institute It states the smaller one end of cone mouth bore and is fixed with inclined plate, the inclined plate length direction tilts and bottom end is fixed with discharge port.

By using above-mentioned technical proposal, four cone mouths of setting make the aluminium slag ball of babinet everywhere uniformly and quickly discharging, It also can avoid cone mouth simultaneously and block the problem for causing discharging difficult.

Further, the babinet is connected with turnover panel, the turnover panel connection babinet and cone with cone mouth connecting pin inner rotation Mouth or isolation babinet and cone mouth.

By using above-mentioned technical proposal, setting turnover panel can control the flow of aluminium slag ball, ensure aluminium slag ball in babinet Retain time enough drying.

Further, spring is fixed on the cone mouth outer wall, the spring bottom end is fixed with holder, and the branch is placed on On ground.

By using above-mentioned technical proposal, so that babinet is shaken by the flexible connection of spring during discharging, avoid aluminium Slag ball, which blocks cone mouth, influences discharging effect.

In conclusion the utility model has the advantages that：

1, runner and blade are connected by using extension bar so that runner rotation is the folding of controllable blade, cost of manufacture It is low and convenient for safeguard；

2, the position of runner can be fixed by limiting tray salver and limited post by setting, be ensured in exhaust fan course of work transfer Wheel and leaf position are fixed, and ensure the constant input of gas flow；

3, avoid single outlet is blocked from influencing discharging by the way that multiple cone mouths are arranged in the bottom of box；

4, by spring supporting babinet, in discharging, babinet, which shakes, shakes aluminium slag ball go out cone mouth, reduces what cone mouth was blocked Probability.
