Summary of the invention
The purpose of this utility model has provided the board-like coal supply valve of a kind of lattice, and it has the dual-use function of even feeding and dense block gas in fluid bed, can solve the problem that prior art exists.
The purpose of this utility model is achieved through the following technical solutions: the board-like coal supply valve of lattice, comprise valve body, valve body is installed powder funnel and discharge bucket up and down respectively, discharge bucket and powder funnel communicate with the inner chamber of valve body respectively, installation shaft in the valve body, one end of axle stretches out outside the valve body and is connected with engine installation, the periphery of axle is installed adapter sleeve, adapter sleeve is connected with axle by attaching parts, at least three blocks of lattice plates are installed on the adapter sleeve, the lattice plate is separated into a plurality of cavitys of leak free with inner chamber, the quantity of the quantity dative plate of cavity is identical, the lattice plate all is positioned at inner chamber, and the periphery of lattice plate is all installed lattice plate liner, and the inner bending section of lattice plate liner between two lattice plates all is arc transition with the outer bending segment that qualifying plate liner is positioned at lattice plate top.
For further realizing the purpose of this utility model, can also realize by the following technical solutions: valve body is connected and composed by cylindrical shell, first end cap and second end cap, and first end cap and second end cap lay respectively at the two ends of cylindrical shell.The both sides of cylindrical shell are offered access hole respectively, and the access hole place all is equipped with the maintenance flap.On the inwall of cylindrical shell inner covering is set.Described engine installation is an electrical motor.The inner bending section of lattice plate liner is connected with adapter sleeve by bolt.
Good effect of the present utility model is: it is equipped with the lattice plate, the lattice plate can become separated by spaces in the valve several fully enclosed independence cavitys, after coal charge enters above-mentioned arbitrary cavity by powder funnel, in the process that rotates to discharge bucket by powder funnel, coal charge is evenly distributed, thereby the realization even feeding, and can prevent that waste gas is blown out by the inlet point place in the fluid bed and pollute.The utility model also has compactness simple for structure, makes adult advantage cheap and easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is that the structure for amplifying scheme drawing is looked on the left side of Fig. 1.
Number in the figure: 10 11 adapter sleeves of 1 cylindrical shell, 2 discharge bucket 3 powder funnels, 4 maintenance flap 5 electrical motor 6 inner chambers, 7 lattice plate 8 lattice plate liners, 9 attaching partss, 12 inner coverings, 13 inner bending sections, 14 first end caps, 15 second end caps, 16 outer bending segments.
The specific embodiment
The board-like coal supply valve of lattice described in the utility model, comprise valve body, valve body is installed powder funnel 3 and discharge bucket 2 up and down respectively, discharge bucket 2 and powder funnel 3 communicate with the inner chamber 6 of valve body respectively, installation shaft 10 in the valve body, one end of axle 10 stretches out outside the valve body and is connected with engine installation, the periphery of axle 10 is installed adapter sleeve 11, adapter sleeve 11 is connected with axle 10 by attaching parts 9, at least three blocks of lattice plates 7 are installed on the adapter sleeve 11, lattice plate 7 is separated into a plurality of independent cavitys of leak free with inner chamber 6, the quantity of the quantity dative plate 7 of cavity is identical, lattice plate 7 is positioned at inner chamber 6, the periphery of lattice plate 7 is all installed lattice plate liner 8, as shown in Figure 2, it is the periphery that lattice plate liner 8 covers in possessive case plate 7 and adapter sleeve 11, the inner bending section 13 of lattice plate liner 8 between two lattice plates 7 all is arc transition with the outer bending segment 16 that qualifying plate liner 8 is positioned at lattice plate 7 tops, the structure of arc transition can make in the inner chamber 6, be between the two lattice plates 7 or there is not sharp-pointed angle in the top of lattice plate 7, can prevent the generation of buildup or sizing phenomenon effectively.The effect of adapter sleeve 11 is to make lattice plate liner 8 connected parts can constitute the bigger circular arc of radius, to play the effect of preventing materials accumulation and anti-sizing.Engine installation drives lattice plate 7 by axle 10 and adapter sleeve 11 and rotates.Learn that according to a large amount of experiments the quantity of lattice plate 7 is at 6 o'clock, result of use is best.
During use, coal charge is poured in the powder funnel 3, coal charge enters a sealed cavity between the two lattice plates 7 through powder funnel 3, under the rotation of lattice plate 7, coal charge is rectangular distribution in above-mentioned sealed cavity, and when this cavity during with discharge bucket 2 corresponding communicating, coal charge is sent in the fluid bed uniformly.In the continuous rotation process of lattice plate 7,, and also has coal powder filled this gap because lattice plate 7 is very little with the gap of valve interior wall, thereby, make the gas in the fluid bed to blow out by powder funnel 3, can play the effect of good dense block gas, prevent dust pollution through lattice plate 7.
For ease of processing and manufacturing, as shown in Figure 1, valve body can be connected and composed by cylindrical shell 1, first end cap 14 and second end cap 15, and first end cap 14 and second end cap 15 lay respectively at the two ends of cylindrical shell 1.First end cap 14, second end cap 15 can be connected and fixed by bolt and cylindrical shell 1, also can be connected and fixed by existing modes such as welding.
After long-time use, just in case when the stifled problem of blowing card occurring, for ease of solving, as shown in Figure 1, the both sides, front and back of cylindrical shell 1 can be offered access hole respectively, a maintenance flap 4 is respectively installed at each access hole place.When needing the cleaning valve inner, only need maintenance flap 4 is opened, can clear up by access hole.
For the situation that further prevents valve inner buildup or sizing takes place, as shown in Figure 2, inner covering 12 is set on the inwall of cylindrical shell 1.Lattice plate liner 8 and inner covering 12 can all be made of stainless steel material.
Described engine installation can be an electrical motor 5, also can be HM Hydraulic Motor, can also be existing other engine installations that axle 10 rotates that drive.
For making things convenient for the inner bending section 13 of fixed grating plate liner 8, the inner bending section 13 of lattice plate liner 8 is connected with adapter sleeve 11 by bolt.The utility model not technology contents of detailed description is known technology.
