Abstract
The utility model belongs to the technical field of cement production equipment, and provides a first-level automatic double-flap wind blockage valve which comprises a tank body, an inlet end and an outlet end of the tank body and two dead-weight valve plates inside the tank body. The dead-weight valve plates are arranged on the inner wall of the tank body and close to the inlet end, an inspection door is arranged on the upper portion of the tank body, and a penetrating shaft is arranged on the inspection door to fix. The wind is locked by dead-weight of the valve plate and discharging powder lots. The first-level automatic double-flap wind blockage valve is simple in structure, energy-saving and consumption-reducing, good in using effect and convenient to repair and change.
Description
Technical field
The utility model belongs to the cement manufacture plant technical field, relates to the automatically two turnover panel air valves of a kind of one-level.
Background technology
The raw meal grinding system that uses at cement production enterprise, two whirlwind tube blanking parts are former to dispose the blanking of two lattices wheel blanking devices, but in use; Usually take place because the blanking of two whirlwind tubes is inhomogeneous, little when big during the blanking amount, thus cause lattice wheel blanking device some faults often to occur; These faults mainly show as lattice wheel shaft pressure-bearing retaining and come off voluntarily, and packing_seal lost efficacy, and it is serious to leak material; Bearing lubrication mechanism is destroyed, and causes maintenance frequent, has influence on the continuous operation of raw material mill; Thereby cause mill raw material quality fluctuation big, directly influence the kiln system process stabilizing.Enterprise usually causes grinding machine repeatedly to stop using thus, and lubricating oil increases, and the bearing replacing number of times increases, and the enterprise production cost correspondingly increases.
Summary of the invention
The inventor is in the daily course of work; Find that the grinding system that existing cement production enterprise generally uses in use exists above-mentioned defective; Through design improvement, a kind of automatically two turnover panel air valves of one-level that wind is effective, maintenance is convenient and energy-conservation of locking are provided during the utility model technical problem to be solved.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is the automatically two turnover panel air valves of the one-level that the designed entrance point and the port of export that comprise casing, casing, two deadweight valve plates in the casing; Said deadweight valve plate is arranged on the cabinet wall near entrance point; Inspection door is offered on top at casing, establish on the inspection door wear the axle fix.
The utility model adopts the automatically two turnover panel air valves of one-level that technique scheme designed; Two valve plates are installed in airtight casing one side; Lean on the one hand the effect of valve plate self gravitation to seal, lean on the sealing of letting out material down effectively to lock wind on the other hand, owing to two deadweight valve plates arranged side by side about on the inwall of flap valve casing, being provided with; Lean on during use the valve plate deadweight and under let out powder and lock wind; Can change valve plate easily through inspection door, the utlity model has simple in structure, energy-saving and cost-reducing, result of use is good, the advantage of convenient maintenance and replacement.
Description of drawings
Fig. 1 representes the structural representation of the automatically two turnover panel air valves of the utility model one-level.
The specific embodiment
Specify below in conjunction with the structure of accompanying drawing the automatically two turnover panel air valves of the utility model one-level.
Referring to Fig. 1, the structure of the automatically two turnover panel air valves of the utility model one-level comprises a tetragonal airtight flap valve casing 6, the material inlet end 1 and the material outlet end 7 of flap valve casing 6; On the inwall of flap valve casing 6, establish 4,5, two deadweights of two deadweight valve plates arranged side by side valve plate 4 up and down near material inlet end 1; 5 lean on valve shaft 9,8 separately to be fixed on the inwall of flap valve casing 6, offer the inspection door 3 that is used to overhaul on the top of flap valve casing 6; Inspection door 3 usefulness wool felts seal; Establish on the inspection door 3 and wear axle 2, wear axle 2 usefulness wedge angle irons and fix, to make things convenient for folding inspection door 3.
The utility model leans on the effect of valve plate self gravitation to seal on the one hand, on the other hand by under let out material sealing effectively lock wind.When blanking amount hour, only lean on the action of bottom valve plate just can satisfy the blanking needs, when the blanking amount was big, the top valve plate was opened the release material automatically under the thrust of material.For guaranteeing lock wind effect, can be seated in the turnover panel one side with the permanent magnetic iron plate, can adjust the valve plate counterweight flexibly like this.The utility model maintenance is very convenient, when the valve plate serious wear, can open the top inspection door; Directly change old valve plate with the valve plate that processes in advance and get final product, joint time worker, the utility model is a kind of blanking device that need not any transmission power; Consumes energy not; Long service life, the casing of sealing need not to lubricate, and practices thrift the oil product resource.
