Abstract

The utility model relates to a power-driven double-layer cinder valve, which comprises a motor, a reduction box and a valve body. The valve body comprises a first cinder chamber and a second cinder chamber which are respectively provided with a cinder inlet and a cinder outlet. The cinder outlet of the first cinder chamber is in butt joint with the cinder inlet of the second cinder chamber. A first valve plate shaft is installed in the first cinder chamber, and an upper arm rod is fixed on the right shaft end of the first valve plate shaft. A second valve plate shaft is installed in the second cinder chamber, and a lower arm rod is fixed at the right shaft end of the second valve plate shaft. Dust covers are installed on the outsides of the upper arm rod and the lower arm rod. The motor is connected to the reduction box which is installed at the middle portion of the dust cover. An output shaft of the reduction box extends into the dust covers, and pull arms are installed on shaft ends. Furthermore, two arc valve plats are formed by an arc plate and two L-shaped connecting plates. The two arc valve plates are respectively installed on the first valve plate shaft and the second valve plate shaft, and springs are connected between the arc valve plates and a valve body wall. The power-driven double-layer cinder valve is good in sealing, stable in operation and long in service life. Furthermore, the power-driven double-layer cinder valve is not easy to damage.

Description

The double electrical layer unloading valve

Technical field:

The utility model relates to a kind of unloading valve that is used for industries such as metallurgy, chemical industry, mine, particularly a kind of double electrical layer unloading valve.

Background technique:

The dusting apparatus that in metallurgy industry, uses, sintering machine or Coolers will be discharged the particulate dust in air blast or the exhausting system, avoid outside wind to get into air blast or exhausting system inside again effectively.In the prior art, the form of Double-deck cinder discharge valve sealed valve has hydraulic rod to promote the method for flashboard.Adopt hydraulic rod to promote upper and lower valve plate and close ash outlet, this structure causes sealing effect poor.Hydraulic rod is had relatively high expectations to working environment, and ash outlet works under hard conditions, and is fragile, and the repair and maintenance amount is bigger, and working life is shorter.

Summary of the invention:

The present invention is in order to solve deficiency of the prior art, a kind of good sealing effect to be provided, and is lower, stable to the working environment requirement, the double electrical layer unloading valve that the long service life easy access is safeguarded.

In order to address the above problem the utility model a kind of double electrical layer unloading valve is provided, has comprised motor, speed reducer, valve body, said valve body comprises first grey chamber and the dual ash chamber; Two grey chambers are respectively equipped with an ash inlet and an ash outlet, and the ash outlet of the first grey chamber docks with the ash inlet of dual ash chamber, indoor first valve shaft that perforation is housed of first ash; The said first valve shaft right side axle head is fixed with armed lever, indoor second valve shaft that perforation is housed of second ash, and the said second valve shaft right side axle head is fixed with lower arm rod; Dust-proof cover is equipped with in said upward armed lever and lower arm rod outside, and motor is loaded on speed reducer top, and speed reducer is loaded on the dust-proof cover middle part; Speed reducer output shaft stretches into dust-proof cover inside; Axle head is equipped with and pulls out arm, also comprises two arc valve plates, and said arc valve plate is made up of an arc plate and two L shaped connecting plates; Said L shaped connecting plate tail end is provided with axis hole, and the axis hole upper center is provided with spring connecting hole.Two arc valve plates are loaded on respectively on first valve shaft and second valve shaft, and the cambered surface of arc valve plate contacts with the ash inlet of corresponding grey chamber, are connected with spring between arc valve plate and the valve body wall respectively.

This sealing structure is effective.All structures of the utility model are mechanical structure and working environment are required lower, adapt to various environment, and are not fragile, the repair and maintenance amount more not, structural stability, working life is longer.

Among the figure: valve body grey chamber 21, the first, arc valve plate 3, the first valve shafts 4, ash outlet 5, ash inlet 6; Dual ash chamber's 7, the second valve shafts 8, lower arm rod 9 pulls out arm 10, speed reducer 11; Motor 12, last armed lever 13, dust-proof cover 14, spring 15, baffle plate 16; Service hatch 17, arc plate 18, L shaped connecting plate 19, axis hole 20, spring connecting hole 21.

Embodiment

Like Fig. 1-shown in Figure 5, a kind of unloading valve comprises valve body grey chamber 21, the first, arc valve plate 3, the first valve shafts 4; Ash outlet 5, ash inlet 6, the dual ash chamber 7, the second valve shafts 8, lower arm rod 9 pulls out arm 10; Speed reducer 11, motor 12, last armed lever 13, dust-proof cover 14, spring 15, baffle plate 16; Service hatch 17, arc plate 18, L shaped connecting plate 19, axis hole 20, spring connecting hole 21.Said valve body 1 comprises that the ash outlet 5 that the first grey chamber 2 and dual ash chamber grey chambers 7, two are respectively equipped with an ash inlet 6 and ash outlet grey chambers 25, the first docks with the ash inlet 6 of dual ash chamber 7; First valve shaft 4 of perforation is housed in the first grey chamber 2, and said first valve shaft, 4 right side axle heads are fixed with second valve shaft 8 that perforation is housed in armed lever 13, the dual ash chamber 7; Said second valve shaft, 8 right side axle heads are fixed with lower arm rod 9, and the said armed lever 13 of going up is equipped with dust-proof cover 14 with lower arm rod 9 outsides, and motor 12 is loaded on speed reducer 11 tops; Speed reducer 11 is loaded on dust-proof cover 14 middle parts; Speed reducer 11 output shafts stretch into dust-proof cover 14 inside, and axle head is equipped with and pulls out arm 10, also comprises two arc valve plates 3; Said arc valve plate 3 is made up of an arc plate 18 and two L shaped connecting plates 19; Said L shaped connecting plate 19 tail ends are provided with axis hole 20, and axis hole 20 upper center are provided with spring connecting hole 21, two arc valve plates 3 and are loaded on respectively on first valve shaft 4 and second valve shaft 8; The cambered surface of arc valve plate 3 contacts with the ash inlet of corresponding grey chamber 5, is connected with spring 15 between arc valve plate 3 and the valve body wall respectively.
