It refers to the process of putting solid waste that meets or meets the kiln entry requirements into the cement kiln, and realizing the harmless disposal of solid waste while producing cement clinker. When solid waste is co-treated in the cement kiln, it is necessary to ensure the complete combustion of the solid waste and the disposal efficiency.

[0003] After searching, Chinese patent publication number CN219545946U discloses a material conveying device for co-disposing solid waste in a cement kiln, comprising a support frame, a driving mechanism is arranged inside the support frame, a dust suction mechanism is also arranged inside the support frame, and the outside of the dust suction mechanism is connected to a first mounting mechanism and a second mounting mechanism, a cavity is arranged inside the dust suction mechanism, and a moving mechanism is also arranged inside the cavity. The bristles on the top of the movable pipe of the material conveying device for co-disposing solid waste in the cement kiln clean the surface of the conveyor belt, and the cleaned residue will be absorbed into the vacuum cleaner through the dust suction hard pipe, so that the impurities on the outer wall of the conveyor belt are cleaned, so that the conveyor belt can be used for a longer time and has a longer life. However, the device lacks measures for handling larger solid wastes compared with the prior art, and when the solid waste is too large or too hard, it will cause material jamming, affecting the conveying work, and will also lead to insufficient combustion after being transported to the cement kiln, affecting the disposal effect.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figure 1 — Figure 7As shown, a material conveying device for co-disposing solid waste in a cement kiln comprises a mounting shell 101, a conveying assembly 102 is mounted on the mounting shell 101, a power assembly of the conveying assembly 102 is arranged inside the mounting shell 101, a plurality of reinforcing rollers 103 for enhancing the load-bearing capacity of the conveying assembly 102 are rotatably connected in the mounting shell 101, a cleaning mechanism for cleaning the conveying assembly 102 is installed in the mounting shell 101, a plurality of groups of crushing mechanisms are arranged in the mounting shell 101, a plurality of groups of connecting mechanisms are installed on the mounting shell 101, each group of connecting mechanisms comprises two mounting columns 301 arranged opposite to each other, and a connecting plate movable left and right is connected to the mounting column 301 by bolts 302, the connecting plate 302 is slidably connected to the top of the mounting shell 101, each group of crushing mechanisms includes an extrusion shell 201, the top of the extrusion shell 201 is rotatably connected to a connecting ring 202 that moves up and down, the connecting ring 202 is slidably connected to the mounting column 301, and a plurality of crushing teeth 203 are slidably connected to the extrusion shell 201. The crushing teeth 203 are used to crush solid waste. When larger solid waste passes between each group of extrusion shells 201, the solid waste will squeeze the extrusion shell 201 open to prevent the solid waste from being stuck in front of the extrusion shell 201. At the same time, under the action of the connecting mechanism, the crushing teeth 203 will extend outward relative to the extrusion shell 201 and crush the solid waste with greater force.

[0027] In this embodiment, the cross-section of the extrusion shell 201 is an inverted trapezoid, and the crushing teeth 203 on the two extrusion shells 201 of each group are arranged alternately. The crushing teeth 203 on each extrusion shell 201 are equidistantly distributed around the circumference and are provided with several layers. The crushing teeth 203 on the two extrusion shells 201 are arranged alternately, and cooperate with each other to crush larger solid waste, thereby ensuring a good crushing effect.

[0028] In this embodiment, a plurality of conical rings 305 are welded on the mounting column 301, and the angle between the inclined surface of the conical ring 305 and the horizontal plane is less than 45°. The conical ring 305 is used to move the crushing teeth 203 outward relative to the extrusion shell 201 when the extrusion shell 201 moves upward. When the solid waste is squeezed and the extrusion shell 201 is lifted, the crushing teeth 203 extend out of the extrusion shell 201, and the higher the height of the extrusion shell 201 is lifted, the closer the distance between the crushing teeth 203 arranged on the two extrusion shells 201 is, and the stronger the crushing force on the solid waste is.

[0029] In this embodiment, a sliding shaft 303 is slidably connected to the connecting plate 302, and the sliding shaft 303 is connected to the top of the mounting shell 101 by bolts. A spring 304 is installed on one side of the connecting plate 302, and a limited position seat 306 is welded at the bottom of the mounting column 301. When the extrusion shell 201 is moved to the left and right sides, the spring 304 is compressed, so that the extrusion shell 201 and the crushing teeth 203 can produce an extrusion and crushing effect on the solid waste.

[0030] In this embodiment, two symmetrically arranged guide plates 104 are connected to the front side of the mounting shell 101 by bolts, and the guide plates 104 are used to guide large particles of solid waste to the center position.

[0031] In this embodiment, the cleaning mechanism includes a rocker arm 401, and a roller brush 402 for cleaning the transmission component 102 is rotatably connected to the top of the rocker arm 401. A connecting tube 403 is welded to the side of the rocker arm 401. The connecting tube 403 is rotatably connected to the inside of the mounting shell 101. A torsion spring 404 is arranged in the connecting tube 403, and the other end of the torsion spring 404 is mounted on the inner wall of the mounting shell 101. When there are adhesions on the transmission component 102, the roller brush 402 on the rocker arm 401 can brush off the adhesions. If the adhesions accumulate, the roller brush 402 will be squeezed. At this time, the rocker arm 401 tilts forward, the connecting tube 403 rotates, and the torsion spring 404 generates torque to enhance the cleaning effect.

[0032] Working principle: When the device is in use, the staff will send the solid waste that needs to be co-disposed of in the cement kiln to the front end of the conveying component 102, and the conveying component 102 will send the solid waste to the installation shell 101. Smaller or powdered solid waste will pass through the guide plate 104 and the bottom of the extrusion shell 201 and enter the next processing position. If larger solid waste is encountered, due to the inclined surface setting at the bottom of the extrusion shell 201, the solid waste agglomerates will squeeze and lift the extrusion shell 201 to prevent the solid waste from being stuck in front of the extrusion shell 201. At the same time, when the extrusion shell 201 is moved to the left and right sides, the spring 304 is compressed, and the extrusion shell 201 is driven to rotate by the solid waste, so that the extrusion shell 201 and the crushing teeth 203 can produce extrusion and crushing effects on the solid waste. When the extrusion shell 201 is opened and lifted, the extrusion shell 201 moves upward relative to the mounting column 301, and the crushing teeth 203 are squeezed by the conical ring 305, so that the crushing teeth 203 move outward relative to the extrusion shell 201, and the higher the height of the extrusion shell 201 is lifted, the closer the distance between the crushing teeth 203 arranged on the extrusion shell 201 of the same group is, and the stronger the crushing force for the solid waste is, thereby improving the crushing effect, which is beneficial to the subsequent cement kiln to coordinately process the solid waste. As the transmission proceeds, adhesions will remain on the transmission component 102, and the roller brush 402 on the rocker 401 can brush off the adhesions. If the adhesions accumulate, the roller brush 402 will be squeezed, and at this time the rocker 401 tilts forward, the connecting pipe 403 rotates, and the torsion spring 404 generates torque to enhance the cleaning effect.
