Abstract

The utility model relates to a dust hopper ash conveying block crushing device of a dust remover, which comprises an ash hopper and a crushing device, wherein an ash outlet at the bottom of the ash hopper is connected with a bin pump through a pipeline, a gate valve is arranged at the ash outlet, and the crushing device is arranged above the ash outlet of the ash hopper and connected with the ash hopper through a fixing seat.

Description

Ash conveying and ash block crushing device of ash hopper of dust remover

Technical Field

The utility model relates to a dust hopper ash conveying block crushing device of a dust remover.

Background

Flue gas generated by coke oven coking enters a desulfurization and denitrification system through an underground flue, the flue gas is mixed with baking soda powder ground and sprayed by a grinder in the flue and then enters a desulfurization tower for reaction desulfurization, the desulfurized flue gas enters a dust remover, dust and desulfurized ash are adsorbed on a filter bag, compressed air sprayed on the top of the dust remover enters the filter bag from top to bottom at the outlet of the filter bag in the opposite direction of gas removal, the dust adsorbed outside the filter bag is cleared down to an ash bucket below, and the dust is conveyed to an ash warehouse through an ash bucket pump. Because coke oven flue gas contains tar and steel plate crack cover plate infiltration etc. in the dust remover use, cause the desulfurization ash in the ash bucket to wet the caking, lead to ash conveying storehouse pump and ash conveying pipeline to block up, ash conveying system routine maintenance is frequent, influences the normal ash conveying of system.

Disclosure of Invention

Aiming at the problems existing in the prior art, the utility model provides the ash conveying block crushing device of the ash hopper of the dust remover, which can crush the desulfurization ash blocks of the ash hopper of the desulfurization and denitrification dust remover of the coke oven, improve the working efficiency of an ash conveying system and reduce the dredging and overhauling workload of a bin pump and an ash conveying pipeline.

The utility model solves the technical problems as follows: the utility model provides a dust remover ash bucket ash conveying ash piece breaker, includes ash bucket and breaker, ash bucket bottom ash hole is through the pipe connection storehouse pump to be located this ash hole department and be provided with the push-pull valve, be provided with simultaneously above ash bucket ash hole breaker, this breaker is connected with the ash bucket through the fixing base.

The technical scheme of the utility model is further defined as follows:

Preferably, the crushing device comprises a crushing rotating rod, a speed reducer and a driving motor, wherein the crushing rotating rod is rotationally arranged inside the hopper, two ends of the crushing rotating rod are fixed on the inner wall of the hopper through bearing blocks, one end of the crushing rotating shaft penetrates through one side of the hopper and is fixedly connected with an output shaft of the speed reducer, the output shaft is arranged on the fixing seat, the speed reducer is connected with the driving electrode, and a plurality of groups of crushing assemblies are arranged on the crushing rotating rod.

Preferably, the number of crushing assemblies is up to 2.

Preferably, each set of crushing assemblies comprises at least two different sizes of crushing blades.

Preferably, the motor driving device further comprises a controller box, and the controller box is connected with the speed reducer and the driving motor through cables.

The utility model has the beneficial effects that: the utility model has simple structure, can realize automatic control through a field control box, when the feeding valve of the ash conveying bin pump is opened, the crushing device is synchronously started, the blockage of the ash conveying bin pump and an ash conveying pipeline caused by the damp agglomeration in the ash hopper can be solved, the crushing rotating rod is arranged above the ash outlet of the ash hopper, a plurality of groups of crushing components are arranged on the crushing rotating rod, each group of crushing components comprises at least two crushing blades with different sizes, the crushing rotating rod is driven to rotate by a speed reducer and a driving electrode, the agglomeration of the ash hopper of the coke oven desulfurization and denitrification dust remover can be crushed, the working efficiency of an ash conveying system is improved, and the dredging and overhauling workload of the bin pump and the ash conveying pipeline is reduced.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model.

Detailed Description

The embodiment provides a dust catcher ash bucket ash conveying ash block crushing device, the structure is shown in figure 1: including ash bucket 1, controller case 2 and breaker, ash bucket 1 bottom ash hole is through pipe connection storehouse pump 3, and be located this ash hole department and be provided with push-pull valve 4, be provided with breaker in ash bucket ash hole top simultaneously, breaker includes broken dwang 5, speed reducer 6 and driving motor 7, broken dwang rotates and sets up inside the hopper, and its both ends are fixed on the hopper inner wall through bearing frame 10, broken pivot one end passes hopper one side simultaneously and installs the speed reducer output shaft fixed connection on fixing base 9, this speed reducer is connected with driving electrode simultaneously, be provided with 2 sets of crushing components on broken bull stick pole, every set of crushing components includes broken blade 8 of at least two kinds of equidimension, the control box passes through cable connection speed reducer and driving motor.

This embodiment simple structure can realize automatic control through the site control case, when the ash conveying storehouse pump feed valve is opened, breaker synchronous start, can solve in the ash bucket desulfurization ash because of the caking that wets, lead to ash conveying storehouse pump and ash conveying pipeline to block up, be provided with broken dwang in ash bucket ash outlet top, be provided with a plurality of broken subassemblies of group on this broken dwang, every broken subassembly of group includes the broken blade of at least two kinds of equidimension, drive broken dwang rotation through speed reducer and driving electrode, can be with coke oven desulfurization denitration dust remover ash bucket desulfurization ash caking broken, improve ash conveying system work efficiency simultaneously, reduce storehouse pump and ash conveying pipeline mediation maintenance work load.
