Abstract

The utility model provides a balance weight flap valve shaft end sealing device. The balance weight flap valve shaft end sealing device is characterized in that the balance weight flap valve shaft end sealing device comprises a balance weight flap valve body, two pairs of sealing mechanisms are arranged on a balance weight flap valve body shaft, each sealing mechanism is a bearing seat fixing shell body which is arranged on the balance weight flap valve body shaft and fixedly connected with the balance weight flap valve body, and a second shaft sleeve, a second seal ring, a bearing, a first seal ring, a first shaft sleeve and a clamp spring are arranged between the bearing seat fixing shell bodies and the balance weight flap valve body shaft. According to the balance weight flap valve shaft end sealing device, raised dust can not enter the bearing on a flap valve shaft, the flexibility of rotation of a flap valve is ensured, the fault rate is greatly lowered, and the blocking accidents and dust are reduced.

Description

Counterweight Flap valve shaft end seal device

Technical field

The utility model belongs to counterweight Flap valve rotating shaft sealing equipment technical field, relates to a kind of counterweight Flap valve shaft end seal device.

Background technique

Dust collector is one of requisite key equipment in manufacture of cement, and plays vital unload ash and the effect of lock wind as the ash-leaking valve of dust collector.The air-box type bag that existing cement production enterprise is used the adopted ash-leaking valve that gathers dust is electronic lattice wheel.As everyone knows, its shortcoming is exactly power consumption, inconvenient maintenance, easily occurs stopping up, and easily leaks ash after the rotating shaft sealing wearing and tearing.In order to overcome electronic lattice wheel power consumption and the poor shortcoming of operational effect, cement production enterprise is proved by analysis and is calculated, and mostly adopts the counterweight Flap valve to replace electronic lattice wheel, it does not need power, rely on the gravity of self to be unloaded ash and lock wind, thereby saving power reduce maintenance cost.But all there is a common shortcoming in the Flap valve of selling in the market: after using a period of time, just start to leak ash after the rotating shaft sealing wearing and tearing and emit ash, not only cause the deterioration of site environment, and after dust enters bearing support, affect the using effect of bearing, cause turnover panel to rotate dumb, turnover panel is not closed completely, dust collector is by the increase of leaking out of turnover panel position, the dust that falls into the Flap valve position that the dust collector filter bag is collected is leaked out rolls the generation reentrainment of dust, cause the dust collector filter bag to inhale ash too much, the dust collector resistance of the filter bag increases, dust collector is processed air quantity and is reduced, and then cause whole dust pelletizing system to draw negative pressure in the phoenix cover to reduce, finally cause the dust removing effects of whole dust pelletizing system to descend.

Summary of the invention

Technical problem to be solved in the utility model is a kind of more perfect, counterweight Flap valve shaft end seal device flexibly of design, utilize this device can prevent the Flap valve axle head because the turnover panel that advances dust and cause is malfunctioning, affect that blanking results in blockage and the series of problems such as on-the-spot airborne dust.

For solving the problems of the technologies described above, technical solution adopted in the utility model is that designed counterweight Flap valve shaft end seal device comprises counterweight turnover panel valve body, establishing two pairs on counterweight Flap valve axon mutually closely fastens and is the contactless sealing mechanism of maze type, every sealing mechanism is to establish the bearing support stationary housing be fixedly connected with counterweight turnover panel valve body on counterweight Flap valve axon, between bearing support stationary housing and counterweight Flap valve axon, from counterweight turnover panel valve body, is connected with successively axle sleeve two, seal ring two, bearing, seal ring one, axle sleeve one and jump ring.

The utility model adopts the designed counterweight Flap valve shaft end seal device of technique scheme, mutually closely fasten and be the contactless sealing mechanism of maze type owing to establishing two pairs on the axle at counterweight turnover panel valve body, make airborne dust can't enter into the bearing the inside on the turnover panel valve shaft, guaranteed the flexibility that Flap valve rotates, rate of fault significantly reduces, leak grey phenomenon and also do not existed, reduced the generation of obstruction accident and the generation of airborne dust.

Embodiment

Structure below in conjunction with accompanying drawing to the utility model counterweight Flap valve shaft end seal device illustrates.

Referring to Fig. 1, the utility model counterweight Flap valve shaft end seal device comprises counterweight turnover panel valve body 9, establishing two pairs on counterweight Flap valve axon 6 mutually closely fastens and is the contactless sealing mechanism of maze type, every sealing mechanism is to establish the bearing support stationary housing 1 be fixedly connected with counterweight turnover panel valve body 9 on counterweight Flap valve axon 6, at bearing support

stationary housing

1 and 6 of counterweight Flap valve axons, from counterweight turnover panel valve body 9, is connected with successively axle sleeve 27, seal ring 28, bearing 4, seal ring 1, axle sleeve 1 and jump ring 3.

Referring to Fig. 2 and Fig. 3, valve plate 13 is connected with the bearing support 10 on valve seat 14, and slip counterweight 12 is connected by weight linear meter 11 with bearing.The utility model installation method is: in the situation that 9 assemblings of counterweight turnover panel valve body put in place, at first counterweight Flap valve axon 6 is inserted and is in place from an end housing body opening, and counterweight turnover panel valve body 9 and counterweight Flap valve axon 6 are welded together from inboard, form connecting rod.Bearing support stationary housing 1 and counterweight turnover panel valve body 9 are connected together, but the center line that will guarantee bearing support stationary housing 1 and counterweight Flap valve axon 6 point-blank, error is controlled in 0.5mm.Then axle sleeve 27, seal ring 28, bearing 4, seal ring 1, axle sleeve 1 and jump ring 3 are installed successively.After this cover sealing configuration is installed and is finished, by weight linear meter 11 together with rotating plate shaft one end vertical welding, on-the-spot narrow limitation of rotating will be considered in welding position, in order to avoid affect free rotational angle, finally slip counterweight 12 is installed, according to the situation of on-the-spot material, debug at the scene the optimum position of slip counterweight 12.

The utility model is on probation through manufacturing experimently, and through again transforming counterweight Flap valve sealing structure of shaft end, and has obtained good effect, and the flexibility that Flap valve rotates improves greatly, and rate of fault significantly reduces, and leaks grey phenomenon and has not also existed, the equipment normal operation.

Claims

1. a counterweight Flap valve shaft end seal device, comprise counterweight turnover panel valve body, it is characterized in that establishing on counterweight Flap valve axon two pairs mutually closely fastens and is the contactless sealing mechanism of maze type, every sealing mechanism is to establish the bearing support stationary housing be fixedly connected with counterweight turnover panel valve body on counterweight Flap valve axon, between bearing support stationary housing and counterweight Flap valve axon, from counterweight turnover panel valve body, is connected with successively axle sleeve two, seal ring two, bearing, seal ring one, axle sleeve one and jump ring.
