Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0057] Embodiment one, please refer to Figure 1 Figure 5 The present application is a screening and conveying device for a kitchen waste treatment equipment, which comprises a shell one 13, a support frame 14 fixedly connected to the outer wall of the shell one 13, a collection box 15 slidingly connected to the inner wall of the support frame 14, a water outlet 16 through-connection at the bottom of the shell one 13, a discharge outlet 17 through-connection at the bottom of the shell one 13, and further comprises:

[0058] A screening mechanism 1 is rotationally connected to the inner wall of the shell one 13, which is used for screening and conveying the kitchen waste; ​

[0059] The cleaning mechanism 2 is fixedly connected to the top of the shell 1, and the cleaning mechanism 2 will run synchronously when the screening mechanism 1 rotates;

[0060] The descaling mechanism 3 is fixedly connected to the inner wall of the cleaning mechanism 2, and drives the descaling mechanism 3 to press and clean the outer wall of the screening mechanism 1 when the cleaning mechanism 2 runs;

[0061] Before the device is used, the support frame 14 is fixed at the desired position, and then the power supply of the screening mechanism 1 is turned on, forcing the screening mechanism 1 to run through the cleaning mechanism 2 to drive the descaling mechanism 3.

[0062] The screening mechanism 1 comprises:

[0063] The isolation assembly 11 is rotatably connected to the inner wall of the shell 1 through the sieve;

[0064] The sieve comprises a rotating pipe 111 rotatably connected to the inner wall of the shell 1, and an inclined through hole 112 is formed in the side wall of the rotating pipe 111;

[0065] The driving assembly 12 is fixedly connected to the inner wall of the shell 1 through the power element;

[0066] The power element comprises a motor 121 fixedly connected to the inner wall of the shell 1, and a gear 1 122 is fixedly connected to the output end of the motor 121;

[0067] The support frame 14 is fixed at the desired position, and the end of the inclined through hole 112 with smaller diameter faces the inlet, then the kitchen waste is thrown into the rotating pipe 111, the power supply of the motor 121 is turned on, because the diameter of the rotating pipe 111 near the inlet is small, the soup and oil stains will drop down through the inclined through hole 112 and flow into the collection box 15 through the water outlet 16, as the hole of the inclined through hole 112 expands, the particles in the kitchen waste will fall into another collection box 15 through the discharge port 17, and the packaging boxes and plastic bags with large volume will be discharged from the outlet of the rotating pipe 111, completing the transportation and screening process of the device.

[0068] The cleaning mechanism 2 comprises:

[0069] The accumulation assembly 21 is fixedly connected to the top of the shell 1 through the fixing element;

[0070] The fixing element comprises an air pressure box 211 connected through the top of the shell 1, and an outer shell 212 is fixedly connected to the side wall of the air pressure box 211;

[0071] The linkage assembly 22 comprises a gear two 221 rotatably connected to the side wall of the air tank 211, a gear three 222 fixedly connected to the side wall of the gear two 221, a gear four 223 rotatably connected to the side wall of the air tank 211, and a gear five 224 rotatably connected to the side wall of the air tank 211, wherein the side wall of the gear five 224 is fixedly connected to a notched gear 225.

[0072] When the gear ring 123 rotates, the gear two 221 and the gear three 222 rotate in the opposite direction, and the gear three 222 drives the gear four 223 and the gear five 224 to rotate.

[0073] The descaling mechanism 3 comprises:

[0074] The pressing assembly 31 is fixedly connected to the side wall of the air tank 211 by a compression member.

[0075] The compression member comprises a sliding rail 311 fixedly connected to the side wall of the air tank 211, a tooth rod one 312 slidably connected to the inner wall of the sliding rail 311, a pressure frame 313 fixedly connected to the side wall of the tooth rod one 312, a piston plate 314 fixedly connected to the bottom of the pressure frame 313, and a spring column 315 slidably connected to the top of the air tank 211.

[0076] The extrusion assembly 32 is fixedly connected to the bottom of the air tank 211.

[0077] The presence of oil stains may cause the plastic bag to stick. The cleaning mechanism 2 and the descaling mechanism 3 are arranged inside the equipment. When the rotating pipe 111 rotates, the gear ring 123 rotates. When the gear ring 123 rotates, the gear two 221 and the gear three 222 rotate in the opposite direction, and the gear three 222 drives the gear four 223 and the gear five 224 to rotate. When the gear ring 123 rotates, the notched gear 225 rotates synchronously. In the normal state, the teeth of the notched gear 225 are in meshing connection with the side wall of the tooth rod one 312. When the notched gear 225 reaches the notch position, the notched gear 225 is no longer in contact with the tooth rod one 312. The spring column 315 releases potential energy, forcing the piston plate 314 to slide downward along the bottom of the air tank 211, extruding the air at the bottom of the piston plate 314. This makes the air at the bottom of the air tank 211 discharge outward from the exhaust port 213, and act on the top of the inclined through hole 112 and discharge outward from the inclined through hole 112. Through the application of the above-mentioned assemblies, the packaging bag is prevented from sticking to the inside of the rotating pipe 111, affecting the screening efficiency of the equipment.

[0078] Example two, please refer to Figure 2 - Figure 10The application discloses a screening and conveying device for a kitchen waste treatment equipment, and belongs to the technical field of kitchen waste treatment equipment.

[0079] Wherein, the inclined through hole 112 is small for the inlet position, and oil dirt blocking is prone to occur. The piston plate 314 is arranged in the equipment, air in the air pressure box 211 is rapidly extruded downward by the piston plate 314, air in the air pressure box 211 is forced, and the inner wall of part of the inclined through hole 112 is cleaned when high-pressure air is sprayed downward through the inclined through hole 112. The high-pressure air passes through the inner wall of the inclined through hole 112, effectively prevents the inclined through hole 112 from being blocked due to oil dirt accumulation, and causes the screening efficiency to be too low.

[0080] The driving assembly 12 comprises a tooth ring 123 fixedly connected to the outer wall of the rotating pipe 111.

[0081] Wherein, the inclined through hole 112 is set in an inclined state, such as Figure Four , Z is an inlet, and H is an outlet. When high-pressure gas flows from top to bottom, the high-pressure gas flows downward through the inclined through hole 112 and sprays the plastic bag downward along a path G. The plastic bag also falls along the direction of the path G, so that the plastic bag is closer to the position of H. Through the application of the above assembly, even if the plastic bag sticks to the inner wall of the rotating pipe 111 again after falling, the plastic bag can slowly move to the outlet position, and finally flow out from the outlet, avoiding the phenomenon that the plastic bag repeatedly sticks and cannot be discharged outward.

[0082] The accumulation assembly 21 comprises a discharge port 213 arranged at the bottom of the air pressure box 211.

[0083] Wherein, the port of the discharge port 213 is attached to the outer wall of the rotating pipe 111. When the pressing assembly 31 extrudes the air in the air pressure box 211, the air at the bottom of the air pressure box 211 is discharged outward from the discharge port 213 and acts on the top of the inclined through hole 112.

[0084] The side wall of the gear two 221 is meshingly connected with the side wall of the tooth ring 123, the side wall of the gear three 222 is meshingly connected with the side wall of the gear four 223, and the side wall of the gear five 224 is meshingly connected with the side wall of the gear four 223.

[0085] Wherein, when the tooth ring 123 rotates, the notched gear 225 is synchronously rotated. In a normal state, the teeth of the notched gear 225 are meshingly connected with the side wall of the tooth rod one 312. When the notched gear 225 reaches a notched position, the notched gear 225 is no longer in contact with the tooth rod one 312. The spring column 315 releases potential energy, so that the piston plate 314 slides downward along the bottom of the air pressure box 211 and extrudes the air at the bottom of the piston plate 314.

[0086] The pressing assembly 31 comprises a through hole 316 formed in the top of the piston plate 314, and a counterweight slide column 318 is slidably connected to the inner wall of the through hole 316, and the bottom of the counterweight slide column 318 is fixedly connected with a plug plate 317;

[0087] The piston plate 314 is characterized by slow upward movement and fast downward movement. When the piston plate 314 is rapidly moved downward under pressure, the gap between the plug plate 317 and the piston plate 314 is too small, and the gap of the inclined through hole 112 is also too small, so that the air in the air tank 211 will flow out upward through the gap between the plug plate 317 and the through hole 316, providing an upward pressure for the plug plate 317. In addition, due to the too fast downward speed of the piston plate 314, the downward speed of the counterweight slide column 318 is lower than that of the piston plate 314. The above two forces will quickly cover the bottom of the through hole 316 when the piston plate 314 slides downward, so that the piston plate 314 forms a sealed plate and extrudes the air in the air tank 211. After the piston plate 314 reaches the bottom, the counterweight slide column 318 drives the plug plate 317 to slide downward along the inner wall of the through hole 316 due to the weight of the counterweight slide column 318, so that external air can enter the air tank 211 through the gap between the plug plate 317 and the through hole 316. Through the application of the above assembly, the negative pressure phenomenon in the air tank 211 during the upward movement of the piston plate 314 is prevented, and the oil dirt in the air tank 211 is extracted through the inclined through hole 112, so that the oil dirt accumulates in the air tank 211, affecting the normal use of the equipment.

[0088] The extrusion assembly 32 comprises a fixed square column 321 fixedly connected to the bottom of the air tank 211, and a plurality of spring sheets 322 are fixedly connected to the bottom of the fixed square column 321, and an inclined block 323 is fixedly connected to the end of the spring sheet 322 away from the fixed square column 321;

[0089] When the rotating pipe 111 rotates, the spring sheet 322 will generate a spring pressure, forcing the inclined block 323 to enter the inside of the rotating pipe 111, and the inclined surface of the inclined block 323 is in contact with the frame of the inclined through hole 112. Through the application of the above assembly, the inclined block 323 can push out the impurities outward, preventing the large hole of the inclined through hole 112 from being buckled due to large block-shaped objects such as bone fragments or bamboo sticks.

[0090] One specific application of this embodiment is: before the device is used, first fix the support frame 14 at the desired position, and ensure that the end of the inclined through hole 112 with smaller diameter faces the inlet, then throw the kitchen waste into the rotating pipe 111, and turn on the power of the motor 121. Because the diameter of the rotating pipe 111 near the inlet is smaller, the soup and oil stains will drip down through the inclined through hole 112 and flow into the collection box 15 through the water outlet 16. As the hole of the inclined through hole 112 expands, the particles in the kitchen waste will fall into another collection box 15 through the discharge outlet 17, and the large packaging boxes and plastic bags will be discharged from the outlet of the rotating pipe 111, completing the process of transportation and screening of the device.

[0091] When the rotating pipe 111 rotates, the rotating pipe 111 will drive the internal auger 113 to rotate synchronously, which makes the kitchen waste in the rotating pipe 111 move from the inlet position to the outlet position under the influence of the auger 113.

[0092] In view of the fact that the existence of oil stains may cause the plastic bags to stick, a cleaning mechanism 2 and a descaling mechanism 3 are arranged in the device. When the rotating pipe 111 rotates, it will drive the gear ring 123 to rotate, which will drive the gear two 221 and the gear three 222 to rotate in the opposite direction, and the gear three 222 drives the gear four 223 and the gear five 224 to rotate. When the gear ring 123 rotates, it will drive the notched gear 225 to rotate synchronously. In the normal state, the teeth of the notched gear 225 are in meshing connection with the side wall of the tooth rod one 312. When the notched gear 225 reaches the notch position, the notched gear 225 is no longer in contact with the tooth rod one 312. The spring column 315 releases potential energy, forcing the piston plate 314 to slide downward along the bottom of the air pressure tank 211, extruding the air at the bottom of the piston plate 314. This makes the air at the bottom of the air pressure tank 211 be discharged from the exhaust port 213, and act on the top of the inclined through hole 112 and be discharged from the inclined through hole 112. Through the application of the above components, it is prevented that the packaging bags stick to the inside of the rotating pipe 111, affecting the screening efficiency of the device;

[0093] In view of the fact that the inlet position inclined through hole 112 is small, it is easy to be blocked by oil stains. The piston plate 314 is arranged in the device. When the piston plate 314 quickly extrudes the air downward, it forces the air inside the air pressure tank 211 to be cleaned. When the high-pressure air is sprayed downward through the inclined through hole 112, it will clean part of the inner wall of the inclined through hole 112. The high-pressure air passing through the inner wall of the inclined through hole 112 effectively prevents the inclined through hole 112 from being blocked due to oil stains accumulation, causing the screening efficiency to be too low.

[0094] By using the characteristics of the above inclined through hole 112 to spray high-pressure gas outward, the inclined through hole 112 is arranged in an inclined state, such as Figure FourThe state of the art, Z is the entrance, H is the exit, when the high pressure gas flows from top to bottom, at this time the high pressure gas will flow down through the inclined through hole 112, and spray the plastic bag outwards along the path G, and the plastic bag will also fall along the direction of the path G, so that the plastic bag is closer to the position of H. Through the application of the above components, even if the plastic bag sticks to the inner wall of the rotating pipe 111 again after falling, the plastic bag can slowly move to the outlet position, and finally flow out from the outlet, avoiding the phenomenon that the plastic bag repeatedly sticks and cannot be discharged outwards.

[0095] By using the characteristics of the slow up and fast down of the piston plate 314, when the piston plate 314 is rapidly moved downward under pressure, due to the small gap between the blocking plate 317 and the piston plate 314, and the small gap of the inclined through hole 112, the air inside the air pressure tank 211 will flow out upward through the gap between the blocking plate 317 and the through hole 316, providing an upward pressure for the blocking plate 317. In addition, due to the too fast downward speed of the piston plate 314, the downward speed of the counterweight slide column 318 is lower than that of the piston plate 314, and the above two forces will quickly cover the bottom of the through hole 316 when the piston plate 314 slides downward, so that the piston plate 314 forms a sealed plate, and the air inside the air pressure tank 211 is extruded. After the piston plate 314 reaches the bottom, due to the weight of the counterweight slide column 318, the counterweight slide column 318 drives the blocking plate 317 to slide downward along the inner wall of the through hole 316, so that the external air can enter the inside of the air pressure tank 211 through the gap between the blocking plate 317 and the through hole 316. Through the application of the above components, it is prevented that negative pressure occurs inside the air pressure tank 211 during the upward movement of the piston plate 314, and oil dirt is extracted through the inclined through hole 112, which causes the oil dirt to accumulate inside the air pressure tank 211, affecting the normal use of the equipment.

[0096] When the rotating pipe 111 rotates, the spring sheet 322 will generate a spring pressure, forcing the inclined block 323 to enter the inside of the rotating pipe 111, and the inclined surface of the inclined block 323 contacts the frame of the inclined through hole 112. Through the application of the above components, the inclined block 323 can push the impurities outwards, preventing the large holes of the inclined through hole 112 from being buckled by large blocky objects such as bone fragments or bamboo sticks.
