Abstract
The utility model discloses an improved structure of an internal mixer feeding door sealing device. Sealing devices in the improved structure are positioned on the sides opposite to two side plates respectively, the sealing devices can flexibly butt against and seal gaps between the side plates and a door plate of the feeding door, original copper strips which are used for pressing and sealing are changed, and pneumatic tubes are used as pressing elements for pressing soft sealing strips so as to achieve sealing of two side edges of the door plate of the feeding door. The improved structure of the internal mixer feeding door sealing device is good in sealing effect, balanced and consistent in sealing and pressing force and free of gaps, effectively prevents dust from being leaked, and guarantees good operating environment and mixing quality.
Description
Technical field
The utility model relates to a kind of structure-improved of banbury mixer gallery port, relates in particular to a kind of structure-improved of sealing device for charging door of internal mixer, is applicable to the sealing of banbury mixer gallery port dual-side.
Background technology
The gallery ports of present common banbury are installed in the upper end of loading hopper antetheca bottom, and are installed between the symmetrically arranged left and right side plate, drive to realize the switch motion of gallery ports by the oil cylinder that communicates with gallery ports.The gallery ports sealing device of existing banbury directly adopts copper bar to seal usually, perhaps adopt structure as depicted in figs. 1 and 2 that the gallery ports both sides are sealed, the copper bar that namely adopts one group of spring or screw etc. to withstand to be clipped between accommodating box and the side plate is realized sealing effectiveness.But since biside plate generally adopt be the hard steel plate, itself and the sealing effectiveness that is similarly between the copper bar of rigid material are not good, the situation of dust leakage very easily occurs, cause operating environment seriously polluted; In use simultaneously because continuous switch gallery ports, thereby easily cause the wearing and tearing of copper bar cause its with the left side plate contact-making surface between the slit increase.Owing to adopting the helicitic textures such as spring or screw to carry out the adjustment of sealing strip compaction degree, so that the holding capacity of sealing strip is unbalanced, easily make sealing strip and side sheet room the discontinuity slit occur simultaneously; And along with access times increase, spring force can constantly reduce, screw thread can produce wearing and tearing etc., the situation of sealing face leakage dust finally still can occur, affects banburying quality and operating environment.
The utility model content
In order to overcome above-mentioned technological deficiency, the utility model provides a kind of structure-improved of sealing device for charging door of internal mixer, and the good sealing effect of sealing device, and the durable easy replacing of seal have improved the machinery operation environment, have reduced fault rate.
The utility model in order to solve the problems of the technologies described above the technical scheme that adopts is:
A kind of structure-improved of sealing device for charging door of internal mixer, comprise symmetrically arranged biside plate, be installed on the feeding door door-plate between the described biside plate, also comprise two sealing devices, described two sealing devices are positioned respectively on the relative side of described biside plate, and described sealing device can softly push against the slit between the described biside plate of sealing and the feeding door door-plate.
Its further technical scheme is:
Described sealing device is comprised of soft sealing strip, clamping element and the accommodating box that is individually fixed on the described biside plate, described soft sealing strip and described clamping element all are placed in the described accommodating box, and described soft sealing strip pushes against and is installed with on described side plate, and described clamping element pushes against and is installed with on described soft sealing strip.
The cross section of described accommodating box is U-shaped structure, and the opening direction of described U-shaped structure is towards side plate.
Described clamping element is the pneumatic tyre pipe.
Useful technique effect of the present utility model is: this structure-improved is installed on respectively the relative side of biside plate, and can softly push against the slit between sealing side plate and the feeding door door-plate, utilize the pneumatic tyre pipe for clamping element compresses soft sealing strip, thereby realize the sealing of feeding door door-plate dual-side, this sealing structure is effective, and the sealing thrust is balanced consistent, is not prone to the slit, effectively prevent the leakage of dust, thereby guaranteed the good and banburying quality of operating environment.

The specific embodiment
In conjunction with Fig. 3 and Fig. 4 the utility model is described in further detail.
A kind of structure-improved of sealing device for charging door of internal mixer, comprise symmetrically arranged biside plate 1, be installed on the feeding door door-plate 2 between the described biside plate 1, also comprise two sealing devices 3, described two sealing devices 3 are positioned respectively on the relative side of described biside plate, and described sealing device 3 can softly push against the slit between the described biside plate of sealing and the feeding door door-plate 2.
Described sealing device 3 is comprised of soft sealing strip 31, clamping element 32 and the accommodating box 33 that is individually fixed on the described biside plate, described soft sealing strip 31 and described clamping element 32 all are placed in the described accommodating box 33, and described soft sealing strip 31 pushes against and is installed with on described side plate 1, and described clamping element 32 pushes against and is installed with on described soft sealing strip 31.The cross section of described accommodating box 33 is U-shaped structure, and the opening direction of described U-shaped structure is towards side plate 1, and described clamping element 32 is the pneumatic tyre pipe.Because each local pressure distribution of pneumatic tyre pipe is even, therefore push against when being installed with on soft sealing strip 31 when it, can make soft sealing strip 31 well-proportioned being adjacent on biside plate 1, can realize good sealing effectiveness.
Soft sealing strip 31 adopts wear-resisting soft material to be prepared from described in the utility model, usually adopts soft wear-resistant macromolecule material to be prepared from, and preferably can adopt Teflon to be prepared from.
