Description

Up-down type ash cleaning medium collecting, air locking and blanking device

Technical Field

The utility model relates to a collecting and air-locking blanking device for an ash removal medium, in particular to a collecting and air-locking blanking device for an ash removal medium of a boiler.

Background

When the boiler is in operation for cleaning ash, an ash cleaning medium such as a steel ball is added to impact and clean the heat exchange surface, and then ash and the steel ball are discharged through an ash hopper and a collecting and air-locking blanking device; the common air-locking discharging devices are all arranged at a single point, are typical of star-shaped ash discharge valves, are usually applied to the outlet of a single ash hopper for use outside the furnace, have few point positions and small ash discharge amount, but are not applicable to the air-locking discharging devices which are arranged on the plane in the furnace and require multiple points and large discharge amount to uniformly pass through.

Disclosure of Invention

The utility model aims to provide an up-and-down type ash cleaning medium collecting and air locking blanking device aiming at the defects in the prior art, which can realize multi-point and large-discharge ash cleaning and slag discharging and meet the requirements of gas locking and falling distribution uniformity of flue gas.

In order to achieve the aim, the vertical type dust cleaning medium collecting and air locking blanking device comprises a box body, wherein an opening is formed in the upper part of the box body; the device is characterized in that a collecting hopper is fixedly arranged outside the opening, a horizontal partition plate is fixedly connected in the box body, more than two inlets are formed in the partition plate, more than two outlets are formed in the bottom plate of the box body, and all the inlets and the outlets are arranged in a staggered mode in the horizontal direction; an upper cover plate passes the preceding curb plate of box body and arranges in on the baffle, and apron passes the preceding curb plate of box body and arranges in on the bottom plate down, and upper cover plate and apron down all are equipped with the via hole more than two, and two liang of a set of via holes of upper cover plate and apron down all overlap the setting in vertical, and the upper cover plate is passed through the connecting plate with the outer one end of apron down in the preceding curb plate and is linked firmly.

When the device is used, ash containing an ash cleaning medium enters the collecting hopper, the upper cover plate and the lower cover plate are moved in a reciprocating manner, when the through holes of the upper cover plate and the lower cover plate are overlapped with the inlet of the partition plate, materials fall onto the lower cover plate, when the lower cover plate continues to move until the through holes of the lower cover plate are overlapped with the outlet of the bottom plate, the materials are discharged from the outlet, the ash cleaning and the slag discharging with multiple points and large discharge amount can be realized, the inlet of the partition plate and the outlet of the bottom plate are always closed or opened by the upper cover plate or the lower cover plate in a discontinuous manner, the condition that the inlet and the outlet are opened simultaneously does not exist, and the gas locking and the leakage prevention of smoke are realized to the maximum extent;

as a further improvement of the utility model, two adjacent inlets of the partition board and two adjacent outlets of the bottom board are arranged at equal intervals, the interval between two adjacent through holes of the upper cover board and the lower cover board is equal to the interval between two adjacent inlets or two adjacent outlets, and the sizes of the inlets, the outlets and the through holes are consistent; the material falling can be uniformly distributed;

in conclusion, the utility model can realize multi-point and large-discharge deashing and deslagging, and meet the requirements of gas locking and falling distribution uniformity of flue gas.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 2, the vertical ash removal medium collecting, air locking and discharging device of the embodiment includes a box body 1 with an opening at the top and a collecting hopper 2 fixedly arranged outside the opening, the box body 1 is composed of a bottom plate, two side plates, a front side plate and a rear side plate which are fixedly connected, a horizontal partition plate 3 is fixedly connected in the box body 1 by welding, the partition plate 3 is provided with two inlets 4, the bottom plate of the box body 1 is provided with two outlets 5, and all the inlets 4 and the outlets 5 are arranged in a staggered manner in the horizontal direction; an upper cover plate 6 penetrates through a through hole of the front side plate of the box body 1 and is arranged on the partition plate 3, a lower cover plate 7 penetrates through a through hole of the front side plate of the box body 1 and is arranged on the bottom plate, two through holes 8 are formed in the upper cover plate 6 and the lower cover plate 7, every two through holes 8 of the upper cover plate 6 and the lower cover plate 7 are longitudinally overlapped, and one ends, located outside the front side plate, of the upper cover plate 6 and one end, located outside the lower cover plate 7, of the lower cover plate 7 are fixedly connected through a connecting plate 9; the two inlets 4 of the clapboard 3 and the two outlets 5 of the bottom plate are arranged at equal intervals, the interval between the two through holes 8 of the upper cover plate 6 and the lower cover plate 7 is equal to the interval between the two inlets 4 or the two outlets 5, and the sizes of the inlets 4, the outlets 5 and the through holes 8 are consistent;

the collecting hopper 2, the box body 1 and the two cover plates are made of high-quality Q355B low-alloy steel plates, the materials are high in heat resistance and structural strength, the two cover plates are freely placed on the partition plate 3 and the bottom plate, the peripheral gaps can ensure free movement, the upper space and the lower space are larger, and the deformation of the two cover plates is allowed to be loose; the space between the upper cover plate and the lower cover plate is used as a temporary steel ball storage space and a channel; when the device is used, after ash removal, ash containing an ash removal medium, namely steel balls enters the collecting hopper 2, the upper cover plate 6 and the lower cover plate 7 are moved to and fro at the same time, when the through holes 8 of the upper cover plate 6 and the lower cover plate 7 coincide with the inlet 4 of the partition plate 3, materials fall onto the lower cover plate 7, and when the lower cover plate 7 continues to move until the through holes 8 coincide with the outlet 5 of the bottom plate, the materials are discharged from the outlet 5, so that ash removal and slag removal with multiple points and large discharge amount can be realized, the inlet 4 of the partition plate 3 and the outlet 5 of the bottom plate are always closed or opened by the upper cover plate 6 or the lower cover plate 7 intermittently, the condition that the inlet and the outlet are opened at the same time does not exist, and the gas locking and leakage of smoke are realized to the maximum extent; and the material can be uniformly distributed;

the utility model can be provided with a plurality of inlets 4, outlets 5 and through holes 8 according to the working conditions.
