Description
Technical Field
The invention relates to the technical field of household garbage treatment, in particular to a multiple sealing structure of household garbage crushing equipment.
Background
The cement kiln co-disposal technology is mature day by day, more and more cement production lines have the RDF co-disposal capability, and the garbage crusher is widely put into use as a core device in the co-disposal technology.
Domestic garbage is not completely classified, the garbage is complex in components and different in shape, various components of metal and nonmetal exist, material particles are distributed unevenly, and the garbage is rich in water and has the characteristic of corrosivity. As domestic household garbage crushing equipment, if the sealing performance cannot adapt to the characteristics of materials, the sealing is very easy to lose efficacy in the operation process, and great hidden dangers are brought to the environment around the equipment and the occupational health of personnel.
Disclosure of Invention
In order to solve the problems that when household garbage is crushed by crushing equipment, the sealing performance is invalid, the surrounding environment is damaged, and the hidden danger to the safety of personnel is caused, the technical problem to be solved by the invention is to provide a multiple sealing structure which meets the current situation of domestic garbage, and the structure is suitable for occasions with complex material particles, various components, high water content and corrosiveness.
The technical scheme adopted by the invention for solving the technical problems is as follows: the multiple sealing structure of the household garbage crushing equipment comprises a movable sealing ring, a static sealing ring and a dewatering disc; the movable sealing ring is arranged on a rotating shaft of the equipment, and the static sealing ring is arranged on the shell; the dewatering disc is installed on the movable sealing ring, steps are arranged on the dewatering disc, the movable sealing ring and the static sealing ring are provided with equally-spaced lugs, and a multi-layer labyrinth sealing structure is formed between the lugs on the movable sealing ring and the static sealing ring.
Wherein, install rotary seal circle between dewatering dish and the casing, realize the movive seal between sealing washer and the dewatering dish.
Wherein, a water-resistant and corrosion-resistant sealing filler is also arranged between the dynamic sealing ring and the static sealing ring to further seal various impurities in the cavity.
The multiple sealing structure of the household garbage crushing equipment has the following beneficial effects:
the multiple sealing structure of the household garbage crushing equipment can solve the problems that the surrounding environment is damaged and hidden dangers to personnel safety are caused due to failure of sealing performance when the crushing equipment crushes the household garbage, and is suitable for occasions with complex material particles, various components, high water content and corrosiveness.

Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1, the invention provides a multiple sealing structure of a household garbage crushing device, which comprises a movable sealing ring 1, a static sealing ring 2 and a water removing disc 3. The dynamic sealing ring 1 is arranged on a rotating shaft 5 of the equipment, and the static sealing ring 2 is arranged on a shell 6; the water removing disc 3 is arranged on the movable sealing ring 1, the water removing disc 3 is provided with steps, the movable sealing ring 1 and the static sealing ring 2 are both provided with equally spaced lugs, and a multi-layer labyrinth sealing structure is formed between the lugs of the movable sealing ring 1 and the static sealing ring 2.
Wherein, install rotary seal 4 between water removal dish 3 and the casing 6, realize the movive seal between sealing washer 4 and the water removal dish 3.
Wherein, a water-resistant and corrosion-resistant sealing filler 7 is also arranged between the dynamic sealing ring 1 and the static sealing ring 2, and further various impurities in the cavity 6 are sealed.
When water removal dish 3 follows rotation axis 5 and rotates, can get rid of the equipment inside with attached to the water on rotation axis 5, reduce during moisture enters into seal structure. Besides, the water removing disc 3 can rotate, materials near the sealing structure can be cleaned, and the phenomenon that the materials are stacked and extruded into the sealing structure to cause sealing failure is avoided. Install sealing washer 4 between except that water tray 3 and the casing 6, this sealing washer 4 is rotary seal, through different structural style, can effectively seal the material in the cavity. Sealing filler 7 is designed between the dynamic sealing ring 1, the static sealing ring 2 and the shell 6, different sealing fillers 7 are selected according to different characteristics of sealing materials, and a second layer of sealing effect is achieved on the materials in the cavity. Multiple labyrinth seals are designed between the static sealing ring 2 and the dynamic sealing ring 1, and a third layer of seal is realized on materials in the cavity. Through the design of such three-layer hierarchical sealed, all the inside materials homoenergetic of cavity are sealed inside effectively, simultaneously because there is not the extrusion of material and the corruption of moisture, sealing performance and sealed life-span obtain very big improvement.
The sealing mechanism comprises labyrinth seal, packing seal, sealing ring seal and moving seal, and has good sealing effect and wide application range.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
