Below in conjunction with accompanying drawing content of the present utility model is described in detail.

Fig. 1 is the structure diagram of one embodiment of the present of invention.

Fig. 2 is the vertical view after Fig. 1 removes Cang Ding.

Fig. 3 is the structure chart of Fig. 1 central authorities aging bunker bin part.

Fig. 4 is the partial enlarged drawing at Fig. 3 A place.

Fig. 5 is the structure chart of Fig. 1 distributing device.

Fig. 6 is the structure chart of Fig. 1 aging bunker newel.

As Fig. 1～shown in Figure 3: aging bunker bin 1 places the center, place, go along with sb. to guard him by one annular storehouse wall 11 and to form, top, storehouse 14 is a conic lid, the Cang Qiang top is provided with circular orbit 12, eaves is provided with a plurality of road wheels 13 under the Cang Ding, and place on the circular orbit 12, so top, conical storehouse 14 can rotate (see figure 4).One end of Rotatruder 2 and mobile trolley used 3 hinged, the other end stretch in the bin vertical hinged with newel 4, and also to withstand on down the eaves infall horizontally hinged with the storehouse for Rotatruder.On this section in Rotatruder stretches into bin, dispose the bucket elevator 5 that moves radially along the Rotatruder work, together rotation of driven rotary conveyer 2 and storehouse top 14 when chassis moves.

Conical storehouse top central authorities are provided with charging hole 15, charging hole 15 is provided with the plane thrust bearing 16 of an internal diameter greater than the charging aperture, accept a revolving top 7 under the center-side of support grasshopper 6, hole, this distributing device and newel 4 top attachment also can be rotated (referring to Fig. 7) around newel.In the raw material ageing process, for avoiding moisture loss, aging bunker should be airtight and airtight.Among the design, Cang Ding is rotating, and its following eaves and Cang Qiangding is that the on-fixed of a relative motion connects, and will seal, though the apical pore also unlikely cross-ventilation that causes in storehouse is arranged herein.The scheme that addresses this problem is: eaves is established a perpendicular annular component under Cang Ding---envelope eaves skirt 17, and its peaceful annular component constitutes "T"-shaped girt 18, and the also available angle steel of this "T"-shaped girt substitutes.A plurality of wheel shafts are housed in order to fixing road wheel 13 on the envelope eaves skirt, the other end of wheel shaft supports with shaped steel.The lower edge of envelope eaves skirt 17 is equipped with the seal 19 that flexible material is made, and the sealing part is L shaped sealing ring, its lower end all the time with Cang Qiangding fit (referring to Fig. 4).

Because the existence of Rotatruder 2, grasshopper 6 does not allow to be provided with support column from the mobile tunnel furnace outer rail in the middle of this segment distance to the center, about tens meters of this segment distance, so the frame of grasshopper must have enough rigidity, if use common grasshopper, certainly will use steel more, increase cost.If adopt general suspension structure, its two ends must be provided with higher column, and this can influence the unimpeded of storehouse jacking material again.The preferred plan that the present invention proposes is that grasshopper adopts special suspension structure, wherein lean on the suspension cable of the segmentum laterale of tunnel cave to be higher than conveyer frame 64, and connect frame 64 with hoist cable 62, lean on the suspension cable of the medial segment of Cang Ding to be lower than conveyer frame 64, and connect frames 64 with strut 63.The advantage of this structure is that the pulling force that suspension cable 61 is produced is born by conveyer frame 64, and conveyer gravity is only born on aging bunker top 14.In addition, the segmentum laterale suspension cable is last, and the current headroom under the conveyer is higher, and the mobile tunnel furnace and the outer haulage vehicle of kiln that help under it pass through; The medial segment suspension cable, can satisfy Rotatruder fully and pass through though the current headroom under it is lower down.

Frame 64 can adopt the recessed arch structure that oppositely rises when grasshopper frame 64 is longer, makes the stage casing of frame 64 some distance that descends when promptly installing.Like this, during the frame pressurized, the middle part is downward flexing, and the hoist cable 62 that is connected with suspension cable 61, strut 63 then limit this flexing and take place, downward flexing power and the counter-force balance of hoist cable and strut, and unlikely unstability, and produce when avoiding frame 64 stressed and arch up.This conveyer frame 64 pressurized unstable phenomenon in the horizontal will be not too serious, because frame 64 is to be made by fixing two parallel bars of belt idler frame, available oblique zeugopodium connects into the truss with triangular structure between these two rod members.But blast will aggravate horizontal unstable phenomenon in the crosswind force larger area.For this reason, can a horizontal vang 65 respectively be set in frame 64 both sides, the two ends of this vang are fixing with conveyer frame 64 respectively, and with cross struts 66 vang 65 is strutted at a certain distance along stands longitudinal, middle strut is the longest, and the strut on both sides shortens respectively gradually.When the vang tensioning, the frame fastening with cross struts then is limited lateral displacement (referring to Fig. 2).

Distributing device in the aging bunker can adopt common chute type structure, optimum structure provided by the invention is as shown in Figure 5: distributing device 7 is made up of portable frame 71 and telescopic conveyer belt 79 two parts, one end of its mid frame 71 is higher, be hinged on the gin pole 4, the other end is lower, by on the top that is supported on storehouse wall 11 by motor-driven roller 76 (referring to Fig. 4).Conveyer belt 79 is walked around the resting barrel 72 of upper end and the movable drum 74 of lower end, walks around gravity tensioning cylinder 77 again.Cylinder 77 is hinged on the frame by connecting rod 78.Movable drum 74 places on the guide rail of frame 71, and links to each other with drive unit 75.On the following methods, rack 71 of top, storehouse charging hole, also be provided with a plurality of carrying rollers 73.When top, storehouse charging hole supplied materials dropped on the conveyer belt, under the gravity effect, conveyer belt rotated, and supplied materials falls in the bin of movable drum 74 belows.Move radially along frame with drive unit 75 control movable drum 74, around gin pole 4 rotations, promptly controlled the drop point of supplied materials, make supplied materials evenly be covered with feed bin with driving rolls 76 control frames.

Central post 4 structures such as Fig. 6 in the aging bunker, this gin pole 4 places the aging bunker center, it is the rotating hinge of Rotatruder, distributing device, be again the slip-ring armature fixed leg that leads to blank machine, mobile tunnel furnace circuit on the chassis, or the location benchmark of mobile tunnel furnace brick field capital construction.Be arranged with distributing device bearing 41 from this column upper end is past successively, Rotatruder bearing 42 and slip-ring armature, and Rotatruder bearing 42 is integrated with slip-ring armature.Be provided with cable aperture 44 in the bottom of column 4.Service cable 45 enters in the gin pole through buried pipe, cable aperture, extends upward with slip ring 43 to be connected, and the cable 46 behind the slip ring is laid along Rotatruder 2, extends to mobile trolley used 3.

Raw material is crossed over mobile tunnel furnace tracks 8 through grasshopper 6, and the charging hole 15 through top, storehouse 14 drops on the distributing device 7, and distributing device 7 is thrown into capacity space after elevator 5 is got sky with supplied materials; Elevator 5 on the Rotatruder 2 is got material and is transported to blank machine 9 on the chassis 3 before distributing device.The length of digestion time depends on property of raw material and technological specification, and after technological specification was determined digestion time, the aging bunker volume determined that promptly on concrete structure, the aging bunker volume size is by aging bunker diameter and degree of depth decision.Under the constant situation of capacity, suitable diameter and depth scale can reduce cost and improve system reliability.The inventor thinks: in the process system of producing 3000 10,000 bricks per year, aging bunker diameter 16-20m, degree of depth 3-5m is advisable, wherein Cang Qiangding preferably exceeds plane, place 2-3m, Rotatruder is rotated on the plane that exceeds place 2-3m, the following place of Plane of rotation just can make full use of, and both stackable manufactured goods also can be planted the flowers and plants vegetables.

The proposition of this improvement project can make the mobile tunnel furnace process system more perfect, and logistics is more smooth and easy, and cost reduces, and cost reduces in the production and operation, particularly can save more labour.
