Abstract
The utility model provides a two -way picture peg door of feeder entry, include: straight section of thick bamboo valve body, lateral cavity valve body, hand wheel, transmission lead screw, flashboard, packing, bearing roller, flange. Straight section of thick bamboo valve body adopts through structure, and the hand wheel drives the flashboard through the transmission lead screw and is two direction switch to be connected with former coal bunker, feeder respectively through the flange, constituted fully enclosed seal structure, the bearing roller plays the support guide effect to the flashboard, realizes through the packing that the axial elasticity is adjustable, closes performance and compensatory can uniting two into one the most at last, need not installation design telescopic joint separately again, and compact structure is equitable, has effectively reduced stagnant coal link.
Description
Technical field
The utility model relates to coal-feeding conveyer technical field, refers to a kind of coal-feeding conveyer entrance Bidirectional plug board door especially.
Background technique
The electronic insertion plate door of the many employings of current power plant's coal-feeding conveyer entrance, electronic insertion plate door generally adopts external motor driven gear to be engaged inner rack-driving, built-in tooth bar and carrying roller rust corrosion under the long-term corrosion function of raw coal, easily deposit coal, lower coal resistance is caused to increase, by bottom old name for the Arabian countries in the Middle East circle reducing and slip joint support the use after cause lower coal apart from long, cause frequent chute blockage.
Model utility content
The purpose of this utility model is exactly the situation for above-mentioned prior art, proposes a kind of coal-feeding conveyer entrance Bidirectional plug board door, perishable to solve existing electronic plate family of power and influence body inner body, the problem of Yi Jimei, chute blockage.
The purpose of this utility model is achieved through the following technical solutions: a kind of coal-feeding conveyer entrance Bidirectional plug board door, it is characterized in that comprising straight tube valve body, chamber, side valve body, handwheel, drive lead screw, flashboard, chamber, side valve body is fixed on the both sides of straight tube valve body, and drive lead screw is placed in the valve body of chamber, side; Handwheel is connected with drive lead screw, and drive lead screw is connected with flashboard.
Further, described a kind of coal-feeding conveyer entrance Bidirectional plug board door also comprises packing, and packing is bolted on straight tube valve body by the flange b and adjustment inserting flange c.
Further, the axial stretching amount of described packing is 30-50mm.
Further, chamber, described side valve body is rectangular structure.
Further, described straight tube valve body communicates with chamber, side valve body, and spacing is the thickness of flashboard.
Further, carrying roller is fixed in the inner side of described straight tube valve body, supports flashboard.
The beneficial effects of the utility model are: be reduced to by former for coal-feeding conveyer electronic insertion plate door and two-wayly split insertion plate door, adopt through tubular construction, straight tube valve body communicates with flashboard two avris chamber valve body, eliminates gate inside and deposits coal point, reduce lower coal resistance; This two-way packing splitting insertion plate door has axial adjustable telescopic simultaneously.Closedown performance and expansion telescopicing performance are united two into one, without the need to mounting design slip joint separately again, compact structure is reasonable, effectively can solve the chute blockage problem of coal-feeding conveyer entrance and run coal bin after installation.

Embodiment
Below in conjunction with accompanying drawing, a kind of coal-feeding conveyer entrance of the utility model Bidirectional plug board door is described further: this embodiment is only not used in restriction scope of the present utility model for illustration of the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model all falls within the application's claims limited range.
As shown in Figure 1, a kind of coal-feeding conveyer entrance Bidirectional plug board door, comprises straight tube valve body 1, chamber, side valve body 11, handwheel 7, drive lead screw 2, flashboard 3, packing 9, and chamber, rectangular side valve body 11 is fixed on the both sides of straight tube valve body 1, communicates each other, and spacing is the thickness of flashboard; Drive lead screw 2 is placed in chamber, side valve body 11, is placed in chamber, side valve body 11 when flashboard 3 is opened, and is placed in straight tube valve body 1 during closedown; Straight tube valve body 1 is connected with run coal bin by flange a4, is connected with coal-feeding conveyer by flange d8; Handwheel 7 is connected with drive lead screw 2 by pivot pin, and drive lead screw 2 is connected with flashboard 3 by bolt, and carrying roller is fixed in the inner side of straight tube valve body, for supporting flashboard; Packing 9 is bolted on straight tube valve body 1 by the flange b5 and adjustment inserting flange c6, and has axial adjustable telescopic.
As shown in Figure 2, coal-fired enter straight tube valve body 1 from run coal bin, rotate handwheel 7 and drive drive lead screw 2 two-way (in figure left and right directions) move, thus control flashboard 3 is two-way splits, fire coal enters coal-feeding conveyer; The carrying roller 10 that round steel makes is welded on straight tube valve body both sides, plays a supportive role to flashboard 3, and the lock gate hatch avoiding other types amasss coal and corrosion, stuck, the phenomenon such as not open due to tooth bar, guide rail; Drive lead screw, flashboard, carrying roller etc. all can adopt stainless steel to make with coal contact component, prevent corrosion; Straight tube valve body 1 ingress is provided with the packing 9 of adjustable telescopic structure, and effectively can absorb the swell increment that run coal bin self brings, compact structure is reasonable.
