Abstract
The utility model discloses a gas locking flap valve of an aluminum oxide gas suspension roasting furnace inclined blanking pipe. The utility model comprises an inclined blanking pipe 8; the utility model is characterized in that a rotating axle 7 penetrating the pipe wall of the blanking pipe is arranged on the blanking pipe, a valve plate 3 for sealing a pipeline is fixed on the rotating axle 7, cranks 6 are fixed at the end parts at the both ends of the rotating axle 7, and balancing weights 5 for adjusting the diversion of the valve plate 3 are arranged on the cranks 6. The utility model can ensure materials to pass through, inverse airflow can not pass through when the airflow is short, and the utility model has the advantages that the running principle and the mechanical structure are simple, only a common worker can perform the maintenance, the production and the maintenance cost are low, and the repair is convenient. In addition, the small cover of the utility model is installed on the blanking pipe surface, the switch is controlled through a radial arm, the utility model can be conveniently opened to perform examination to the valve plate, and the utility model can prevent dust being flying out and hot gas from shedding.
Description
Technical field
The utility model relates to a kind of valve, the Flap valve of the oblique feeding pipe lock of particularly a kind of aluminium oxide gas suspension baking furnace gas.
Background technique
In the aluminium oxide gas suspension baking process, the material that enters venturi drier enters the roasting oven roasting by the air-flow effect after through the preheating of multistage cyclone device and becomes aluminium oxide, again through entering the cooling bed cooling of boiling after the cooling of multistage cyclone device, utilize pipeline that cyclone units at different levels are coupled together, make it form a relatively independent and unified integral body.Wherein, the ducted material of blanking moves by gas flow, when the length of feeding pipe during less than the line length of the normal operation of gas, will cause the air-flow short circuit, airflow obstruction and can't moving on, even toward refluxing has hindered roasting oven and has added and discharge material.For head it off, can be on feeding pipe mounted valve.Existing valve great majority are manually-operated gates, and this just needs the professional to monitor constantly and controls, and because feeding pipe often places higher position, have brought very big inconvenience to operation.In order to overcome these shortcomings of manually-operated gate, work out some automatic valves recently, but existing automatic valve, running principle and structure be comparatively complicated, it is higher to need the professional workforce to safeguard, be difficult for maintenance, fabricating cost and maintenance cost.
Summary of the invention
The purpose of this utility model is, the Flap valve of the oblique feeding pipe lock of a kind of aluminium oxide gas suspension baking furnace gas is provided.The utility model can make material pass through automatically, and reverse air-flow can not pass through when the air-flow short circuit, and has running principle and simple, the common staff of mechanical structure can safeguard, fabricating cost and maintenance cost are low, overhaul characteristics easily.
The technical solution of the utility model is: it comprises oblique feeding pipe 8; Be provided with the rotating shaft 7 of passing tube wall on feeding pipe, be fixed with the valve plate 3 of closed conduct in rotating shaft 7, end, rotating shaft 7 two ends is fixed with crank 6, and crank 6 is provided with regulates the counterweight 5 that valve plate 3 turns to.
In the Flap valve of the oblique feeding pipe lock of above-mentioned aluminium oxide gas suspension baking furnace gas, the perpendicular distance of feeding pipe 8 inwalls is arrived in described rotating shaft 7 greater than rotating shaft 7 to the distance of valve plate 3 terminations.
In the Flap valve of the oblique feeding pipe lock of aforesaid aluminium oxide gas suspension baking furnace gas, also be provided with the tegillum 2 that is used to overhaul valve plate 3 on the tube wall of feeding pipe 8, on tegillum 2, be connected with its spiral arm that opens or closes 1 of control.
Compared with prior art, running principle of the present utility model and mechanical structure are simple, because feeding pipe is tilting, behind the adding material, material is subjected to the self gravitation effect and moves downward, and promotes valve 3 and also it is opened, and material passes through immediately automatically; When the length of feeding pipe during less than the line length of the normal operation of gas, air-flow will be in feeding pipe antikinesis, thereby valve plate is rotated rapidly, when valve plate turns to when contacting with the feeding pipe inwall, blocked by inwall, valve plate is closed automatically, stops the air communication mistake, this just makes the utility model can be safeguarded by common staff, and fabricating cost and maintenance cost are low.In addition, tegillum of the present utility model is installed on the blanking tube wall, controls its switch by spiral arm, can open easily, valve plate is implemented to check, change, and can prevent that dust from flying out and hot gas sheds.
Description of drawings
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is a structural representation of the present utility model;
Being labeled as of accompanying drawing: 1-spiral arm, 2-tegillum, 3-valve, 4-Flap valve, 5-counterweight, 6-crank, 7-rotating shaft, 8-feeding pipe.
Embodiment
Embodiment of the present utility model, a rotating shaft 7 of passing tube wall is installed on existing feeding pipe 8, in rotating shaft 7, fix the valve plate 3 of a closed conduct, one end of valve plate 3 is fixed in the rotating shaft 7, fix two cranks 6 at rotating shaft 7 two ends end positions, install on crank 6 in order to regulate the counterweight 5 that valve plate 3 turns to, the position of counterweight 5 on crank 6 can be regulated.Wherein, rotating shaft 7,, can be blocked by feeding pipe 8 inwalls when making valve plate 3 turn to contact with feeding pipe 8 inwalls greater than the perpendicular distance of rotating shaft 7 to feeding pipe 8 inwalls to the distance of valve plate 3 the other end terminations; The tegillum 2 that is used to overhaul valve plate 3 also is housed on the tube wall of feeding pipe 8, spiral arm 1 is installed on the tegillum 2 of the tube wall outside of feeding pipe 8, make spiral arm 1 can control tegillum 2 and open or close.
Automatically pass through material: because feeding pipe 8 is tilting, behind the adding material, material is subjected to the self gravitation effect and moves downward, and promotes valve 3 and also it is opened, and material passes through immediately.
Automatically stop inverted draft: after material passed through, counterweight 5 gravitates were and sagging naturally, because moment loading, counterweight 5 can drive valve plate 3 and rotate; If the air-flow short circuit takes place, through the impetus of backward motion air-flow, add the induced effect of counterweight 5, thereby valve plate 3 is rotated rapidly, when valve plate 3 turns to when contacting with feeding pipe 8 inwalls, blocked by inwall, valve plate 3 is closed, and the prevention inverted draft passes through.
Inspection of the present utility model: tegillum 2 is installed on the blanking tube wall, by spiral arm 1 its switch of control.Operator outwards lift spiral arm 1 can open tegillum 2 easily, and valve plate 3 is implemented to check; After checking out, promote spiral arm 1, tegillum 2 is closed, to prevent that dust from flying out and hot gas sheds.
