Abstract
A kind of access path of center feeder.The utility model relates to a kind of access path, is specifically related to a kind of access path of center feeder.The utility model is the problem that the work of solution existing center feeder repair and maintenance is difficult to carry out.A kind of access path of center feeder is arranged between silo and interior centrum, and the cross-sectional plane of access path is pentagon, and the right lower end surface of access path is connected with the side of silo, and the lower-left end face of access path is connected with the side of interior centrum.The utility model is used for the maintenance of center feeder.
Description
Technical field
The utility model relates to a kind of access path, is specifically related to a kind of access path of center feeder.
Background technology
Current center feeder is primarily of center feeder body and inner cone composition.Generally, interior centrum is arranged on the inside of silo, center feeder body is connected with the exit end of silo, center feeder body is arranged on immediately below interior centrum, inner cone by 2 or 4 hold-down arms together with silo sidewall weld, it is inner at silo that hold-down arm is in-line or cross arrangement, and the cross-sectional plane of hold-down arm is A font structure, and cross section is less.
In conjunction with real service condition, for the version of above-mentioned center feeder hold-down arm, there is following shortcoming:
When needing to carry out inspection and maintenance work to the inside consumable accessory of center feeder, maintainer must be entered center feeder inside by the entrance door in surge bunker under center feeder, because the coal spout diameter in center feeder is less, limited space, is therefore difficult to carry out repair and maintenance work.Owing to being subject to the effect of gravity and friction force, the loose unpacked material middle part flowing in silo is fast, and near silo inwall, flowing is slow, " center stream " phenomenon often occurred in silo.
Utility model content
The problem that the utility model is difficult to carry out to solve the work of existing center feeder repair and maintenance, and then a kind of access path of center feeder is proposed.
The utility model is solve the problems of the technologies described above the technical scheme taked to be: access path of the present utility model is arranged between silo and interior centrum, the cross-sectional plane of access path is pentagon, the right lower end surface of access path is connected with the side of silo, and the lower-left end face of access path is connected with the side of interior centrum.
The beneficial effect that the utility model compared with prior art comprises is: the utility model structure is simple, cross-sectional plane adopts pentagonal configuration, cross-sectional area and space can be utilized large, be specially adapted to the work condition environment that center feeder diameter is greater than more than 4 meters, be convenient to realize the service work to center feeder inside consumable accessory; The utility model can change the type of flow of loose unpacked material in silo, eradicates interior " center stream " phenomenon often occurred of silo in the past, enables the loose unpacked material entirety in silo fall and flow.
Accompanying drawing explanation
Fig. 1 is the integral structure schematic diagram that the utility model is applied in center feeder; Fig. 2 is the right elevation of access path 1 in Fig. 1.
Detailed description of the invention
Detailed description of the invention one: composition graphs 1 and Fig. 2 illustrate present embodiment, described in present embodiment, a kind of access path 1 of center feeder is arranged between silo 3 and interior centrum 4, the cross-sectional plane of access path 1 is pentagon, the right lower end surface 1-1 of access path 1 is connected with the side of silo 3, and the lower-left end face 1-2 of access path 1 is connected with the side of interior centrum 4.
In design like this, centrum 4 is fixed in the inside of silo 3 by the connection of hold-down arm 2 and supporting role, when the inner consumable accessory of center feeder goes wrong, can be entered by the right lower end surface 1-1 of the access path 1 on silo 3 side, through the other end of access path 1, enter into interior centrum 4 by the lower-left end face 1-2 of access path 1, internal centrum 4 and center feeder body 5 overhaul.
The cross-sectional plane of access path 1 adopts pentagonal configuration, increases the inner space of access path 1, and the cross-sectional area of access path 1 is large, is easy to workman and enters, overhaul.
In addition, the cross-sectional plane of access path 1 is pentagonal configuration, make material in silo when falling, after touching access path 1, multiple sense of motion can be produced along the outer wall of access path 1, thus change the type of flow of loose unpacked material in silo 3, eradicate interior " center stream " phenomenon often occurred of silo in the past, enable the loose unpacked material entirety in silo 3 fall and flow.
Detailed description of the invention two: composition graphs 1 and Fig. 2 illustrate present embodiment, the apex angle α of access path 1 described in present embodiment is 20 ° ~ 50 °.Other composition is identical with detailed description of the invention one with connection mode.
The corner angle of access path 1 is less, and so design can reduce the pressure effect of material to access path 1, makes access path 1 can bear the immense pressure that in silo 3, loose unpacked material produces it.
Detailed description of the invention three: composition graphs 1 and Fig. 2 illustrate present embodiment, described in present embodiment, the apex angle α of access path 1 is 30 °.Other composition is identical with detailed description of the invention two with connection mode.
Design like this combines the demand of the inner space of pressure suffered by access path 1 and access path 1, and when apex angle α is 30 °, the inner space of access path 1 is enough large, and can sustain the pressure effect of material to access path 1.
Detailed description of the invention four: composition graphs 1 and Fig. 2 illustrate present embodiment, described in present embodiment, the lateral surface of access path 1 is provided with wearing layer.Other composition is identical with detailed description of the invention one or three with connection mode.
Wearing layer is the wearing layer of the material making that friction coefficient is lower, design like this can extend the service life of access path 1, saves cost, reduces the resistance of loose unpacked material in access path 1 pair of silo 3, prevent the outside of access path 1 from occurring solid accumulation, " bridging " phenomenon occurs.
Detailed description of the invention five: composition graphs 1 and Fig. 2 illustrate present embodiment, the wearing layer of access path 1 lateral surface described in present embodiment is the wearing layer that wear-resisting steel plate makes.Other composition is identical with detailed description of the invention four with connection mode.
Wear-resisting steel plate is the wear-resisting steel plate that friction coefficient is lower.
Detailed description of the invention six: composition graphs 1 and Fig. 2 illustrate present embodiment, the top of the inside of access path 1 described in present embodiment is provided with lifting slideway 1-3.Other composition is identical with detailed description of the invention one or three with connection mode.
Design lifting slideway 1-3 like this, can shift out associated components very easily or move into inner cone 4, be beneficial to workman and overhaul.
