Abstract
The utility model discloses a wooden scraps separator comprised by a box, a sieve screen, a clear chamber, and a spare screen clear chamber, wherein the box, which is constructed by an outer baffle 2, an inner baffle 3, and a lateral board 1, is left-right movable disposed on the wind channel 1, and the outer baffle is disposed on the exterior wall of the wind channel, and the inner baffle is disposed on the interior wall of the wind channel, and the outer baffle and the inner baffle is connected by the lateral boards which is disposed at both sides of the baffles to form a box with vertically transfixion structure, and the closed clear chamber 7 is disposed at the wind channel part of the outer baffle, and the screen clear chamber 6 which is linked to the wind channel is arranged at the wind channel part of the inner baffle, and the sieve screen includes a main screen 4 and a spare screen 5. The box of the present utility model can left-right move relatively to the wind channel, so that the utility model can prevent cold air enter into the interior of the powder production system when it is in use, thereby guaranteeing the normal operation of the boiler combustion system. And the designed sieve screen can avoid filtration vacuum phenomena happening during clearing the wood scraps, thereby guaranteeing circulation of the wind powder airflow.
Description
Technical field
The utility model belongs to the coal dust separation technology field of boiler milling system, and what relate generally to is a kind of wood scraps separator.
Background technology
Wood scraps separator is an important step in the boiler milling system, its effect be with do not grind in the coal dust wood chip and the foreign material of other bulk separate.At present, the wood scraps separator that electric boiler adopts in pulverized coal preparation system mostly is convertible structure greatly, this wood scraps separator is made of upset screen cloth, upper spacer and lower clapboard, the upset screen cloth works the wind powder effect of filtering, upper spacer has been used the effect that separates foreign material with lower clapboard, has separating effect preferably.But because in use, phenomenons such as landing, ejector pin be malfunctioning can appear in upper spacer and lower clapboard, and cold air enters burner hearth inside, causes combustion instability, even causes fire-putting-out emergency.Because screen cloth is in the process of upset cleaning wood chip, screen cloth is in and breaks away from the filtration state, can form the filtration vacuum during this period, foreign material is entered in an airduct hinder wind powder airflow, even result in blockage.In addition, this wood scraps separator in use also exists complex operation, drawback that labour intensity is big.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of wood scraps separator.It is strong that this wood scraps separator has safety and reliability, characteristics easy and simple to handle.
For achieving the above object, the technical scheme that the utility model is taked is: it is made up of box body, screen cloth, cleaning storehouse and standby screen cloth cleaning storehouse, box body is installed on the air channel and relative air channel move left and right, it is made of outer baffle, Internal baffle and side plate, outer baffle is positioned at the outer wall in air channel, Internal baffle is positioned at the inwall in air channel, and outer baffle and Internal baffle are connected to form the box body structure of up/down perforation by the side plate of both sides; Be provided with airtight cleaning storehouse being positioned at position, outer baffle air channel; Be provided with the screen cloth cleaning storehouse that is communicated with the air channel being positioned at position, Internal baffle air channel, screen cloth comprises screen portion and spare sieve mesh portions, and it is arranged on the box body, and standby screen cloth is positioned at screen cloth cleaning storehouse.
The utility model is reasonable in design, and is simple in structure.Because the box body of design is the air channel move left and right relatively, has in use effectively avoided cold air to enter pulverized coal preparation system inside thus, guarantee the operate as normal of boiler combustion system.Because the filter screen of design has screen portion and spare sieve mesh portions, when the cleaning wood chip, can prevent the filtration vacuum phenomenon like this, guarantee the circulation of wind powder air-flow.Simultaneously can alleviate working strength of workers.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 uses structural representation for the utility model.
Among the figure: 1, side plate, 2, outer baffle, 3, Internal baffle, 4, screen cloth, 5, standby screen cloth, 6, screen cloth cleaning storehouse, 7, the cleaning storehouse, 8, inspection opening, 9, cleaning door, 10, pull bar, 11, the air channel.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As Fig. 1 in conjunction with shown in Figure 2: present embodiment is made up of box body, screen cloth, cleaning storehouse and standby screen cloth cleaning storehouse, box body comprises outer baffle 2, Internal baffle 3 and side plate 1, it is installed on the air channel 11 and air channel move left and right relatively, and its effect is the airtight reliability of assurance.Outer baffle 2 and Internal baffle 3 are connected as a single entity by side plate 1.The area of outer baffle 2 and Internal baffle 3 is greater than the aperture area in air channel 11.Be provided with airtight cleaning storehouse 7 at 11 positions, air channel that are positioned at outer baffle 2, be provided with the screen cloth cleaning storehouse 6 that is communicated with the air channel at 11 positions, air channel that are positioned at Internal baffle 3, screen cloth 4 is arranged on the box body 1, its length is that the twice of box body 1 length is used as standby screen cloth 5, standby screen cloth 5 is an one with screen cloth 4, and standby screen cloth 5 is positioned at screen cloth cleaning storehouse 7.Be provided with inspection opening 8 and cleaning door 9 on cleaning storehouse 7, an end of pull bar 10 is connected with outer baffle 2, and the other end stretches out outside the cleaning storehouse 7.The utility model in use, when needs cleaning wood chip, only need pulling pull bar 10, the outer baffle 2 of box body and screen cloth 4 promptly enter in the screen cloth cleaning storehouse 6, at this moment, Internal baffle 3 air channels 11 are isolated with cleaning storehouse 7, and wood chip together enters cleaning storehouse 7 with box body, fall under gravity into the bottom in screen cloth cleaning storehouse 6.Meanwhile, the Internal baffle 3 of box body moves and is close to thereupon the inwall of air channel opposite side, and standby screen cloth 5 moves to air channel inner filtration wind powder thereupon.After cleaning is finished, promote pull bar 10, the box body return, screen cloth 4 enters air channel 11, and standby screen cloth 5 enters screen cloth cleaning storehouse 6, and at this moment will clear up storehouse 7 isolated with air channel 11 for outer baffle 2, makes to clear up storehouse 7 and be in the sealing shape, opens cleaning door 9 then foreign material are gone out clearly.
