The present application adopts another technical solution to solve the above technical problem. Utility Model Content

[0005] The utility model aims to solve or at least alleviate the problem that the existing garbage disposal device fails to classify the garbage before compression, which easily leads to liquid residue in the garbage after compression and affects the subsequent processing.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] By adopting the above technical solution, when in use, the user first puts the domestic garbage to be processed into the recycling bin through the feed hopper, and then starts the motor to drive the two squeezing rollers to rotate towards each other, and uses the squeezing rollers to squeeze and crush the garbage to squeeze out the residual liquid in the garbage. After being squeezed out, the liquid falls on the screening plate and passes through the screening plate through the water filter holes to flow into the water collecting tank below for collection. Dry garbage cannot pass through the water filter holes with smaller apertures, and slides down along the upper surface of the screening plate to the containing cavity set at the bottom of the recycling bin, thereby realizing the dry and wet separation of garbage. The problem that the existing garbage disposal device does not classify the garbage before compression is avoided as much as possible, which easily leads to liquid residue in the garbage after compression, affecting subsequent processing.

[0009] Optionally, the drainage structure includes a drainage pipe fixedly connected to the bottom of the water collecting tank, one end of the drainage pipe away from the water collecting tank passes through the side wall of the recovery tank and is fixedly connected to the side wall of the recovery tank, and a valve is installed at the connection between the drainage pipe and the side wall of the recovery tank.

[0011] Optionally, a first partition plate and a second partition plate are fixedly mounted on the side walls on opposite sides of the recovery box below the water collecting box, and a feed outlet is formed between adjacent ends of the first partition plate and the second partition plate.

[0012] By adopting the above technical solution, a first partition and a second partition are provided to separate the recycling box, and a discharge port is formed between adjacent ends of the first partition and the second partition, so that dry garbage can be conveniently dropped to the bottom of the recycling box through the discharge port.

[0013] Optionally, the solid recovery structure is a containing cavity formed by the first partition, the second partition, the bottom wall of the recovery box, and the side walls of the recovery box.

[0014] By adopting the above technical solution, the accommodating cavity is used to contain the dry garbage that slides down the screening plate, thereby realizing the separate storage of dry and wet garbage.

[0015] Optionally, a garbage discharge port is provided on the side wall of the accommodating cavity, and a sealing door for sealing the garbage discharge port is hinged on the inner wall on one side of the garbage discharge port.

[0016] By adopting the above technical solution, a garbage discharge port is provided for discharging dry garbage stored in the accommodating chamber, and a sealing door is provided for sealing the garbage discharge port.

[0017] Optionally, a cylinder is fixedly connected to the side wall of the bottom end of the recovery box, a piston rod is installed on the cylinder, the piston rod passes through the cylinder and is fixedly connected to the cylinder, and a compression plate is fixedly connected to the output end of the piston rod.

[0018] By adopting the above technical solution, when the dry garbage falls into the accommodating chamber, the cylinder can be started to drive the piston rod to extend, thereby pushing the compression plate to squeeze the dry garbage in the accommodating chamber and compress the dry garbage.

[0019] Optionally, when the piston rod is in a retracted state, the compression plate is located on a side of the feed opening close to the cylinder.

[0020] By adopting the above technical solution, it is possible to avoid as much as possible the problem of dry garbage falling under the piston rod, which would cause the dry garbage to be unable to be discharged.

[0021] Optionally, wire brushes whose bristles are in contact with the squeezing rollers are provided on the inner walls of the recycling box on both sides of the squeezing roller, and bolts are passed through the wire brushes, which penetrate the wire brushes and are screwed to the inner wall of the recycling box.

[0022] By adopting the above technical solution, when the squeezing roller rotates, it can generate friction with the bristles of the wire brush, and the garbage adhering to the squeezing roller can be cleaned by the wire brush.

[0023] In summary, the beneficial effects of this application are as follows:

[0024] The present application coordinates the structures such as squeezing rollers, motors, screening plates, water filter holes and water collecting boxes. After the garbage is put into the recycling box, the motor is started to drive the two squeezing rollers to rotate towards each other to squeeze the garbage, thereby squeezing the liquid in the garbage. After the liquid is squeezed out and falls, it passes through the water filter holes through the screening plate and flows into the water collecting box for collection. Dry garbage cannot pass through the water filter holes and slides down the screening plate to the containing cavity set at the bottom of the recycling box for storage, thereby achieving dry and wet separation of garbage. This avoids the problem that the existing garbage disposal device does not classify the garbage before compression, which easily leads to liquid residue in the garbage after compression, affecting subsequent processing.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] See also Figure 1-3 The urban domestic waste recycling and processing device includes a recycling box 1 with a feed hopper 2 fixedly connected to the top. When in use, the user can put the domestic waste to be processed into the recycling box 1 through the feed hopper 2 for processing.

[0031] An extrusion and crushing structure is provided in the recovery box 1 below the feed hopper 2, a screening structure is provided below the extrusion and crushing structure, and a solid recovery structure and a liquid recovery structure are provided below the screening structure.

[0032] The extrusion crushing structure includes two extrusion rollers 3 rotatably connected in the inner cavity at the top of the recycling box 1. The two extrusion rollers 3 are meshed with each other through tooth grooves. A motor 4 for driving the extrusion rollers 3 to rotate is fixedly connected to the outer wall of the recycling box 1. When garbage is put into the recycling box 1, the motor 4 can be started to drive the two extrusion rollers 3 to rotate towards each other, and the extrusion rollers 3 are used to squeeze and crush the garbage, and the residual liquid in the garbage is separated by squeezing.

[0033] The screening structure includes a screening plate 5 obliquely arranged below the squeezing roller 3, one end of which is fixedly connected to the inner wall of the recycling box 1, and a water filter hole 6 is provided on the screening plate 5. The liquid recovery structure is a water collecting box 7 fixedly connected to the lower surface of the screening plate 5. The liquid falls on the screening plate 5 after squeezing, and passes through the screening plate 5 through the water filter hole 6 and flows into the water collecting box 7 below to be collected. However, the dry garbage cannot pass through the water filter hole 6 with a smaller aperture, and slides down along the upper surface of the screening plate 5 to the bottom of the recycling box 1, thereby realizing the separation of dry garbage and wet garbage.

[0034] A drainage structure is also installed at the bottom of the water collecting tank 7. When too much sewage is collected in the water collecting tank 7, the sewage can be discharged through the drainage structure.

[0035] Reference Figure 1The drainage structure includes a drainage pipe 8 fixedly connected to the bottom of the water collecting tank 7, one end of the drainage pipe 8 away from the water collecting tank 7 penetrates the side wall of the recovery tank 1 and is fixedly connected to the side wall of the recovery tank 1, and a valve 9 is installed at the connection between the drainage pipe 8 and the side wall of the recovery tank 1. When a lot of sewage is collected in the water collecting tank 7, the user can open the valve 9 and use the drainage pipe 8 to discharge the sewage in the inner cavity of the water collecting tank 7.

[0036] Reference Figure 1 The first partition 10 and the second partition 11 are fixedly mounted on the side walls of the recycling box 1 below the water collecting box 7 on both sides, and a material discharge port is formed between the adjacent ends of the first partition 10 and the second partition 11. The first partition 10 and the second partition 11 are provided to separate the recycling box 1, and a material discharge port is formed between the adjacent ends of the first partition 10 and the second partition 11, so that the dry garbage can fall to the bottom of the recycling box 1 through the material discharge port.

[0037] Reference Figure 1 The solid recovery structure is a receiving cavity 12 formed by the first partition 10, the second partition 11, the bottom wall of the recovery box 1, and the side wall of the recovery box 1. The receiving cavity 12 is used to hold the dry garbage sliding down the screening plate 5, so as to realize the separate storage of dry and wet garbage.

[0038] Reference Figure 1 A garbage discharge port is provided on the side wall of the accommodating chamber 12, and a sealing door 13 is hinged on the inner wall of one side of the garbage discharge port for sealing the garbage discharge port. The garbage discharge port is provided for discharging the dry garbage stored in the accommodating chamber 12, and the sealing door 13 is provided for sealing the garbage discharge port.

[0039] Reference Figure 1 A cylinder 14 is fixedly connected to the side wall of the bottom end of the recycling box 1, and a piston rod 15 is installed on the cylinder 14. The piston rod 15 passes through the cylinder 14 and is fixedly connected to the cylinder 14. A compression plate 16 is fixedly connected to the output end of the piston rod 15. When the dry garbage falls into the accommodating chamber 12, the cylinder 14 can be started to drive the piston rod 15 to extend, thereby pushing the compression plate 16 to squeeze the dry garbage in the accommodating chamber 12 and compress the dry garbage.

[0040] Reference Figure 1 When the piston rod 15 is in a retracted state, the compression plate 16 is located on the side of the discharge port close to the cylinder 14. It can avoid the dry garbage falling below the piston rod 15 as much as possible, resulting in the problem that the dry garbage cannot be discharged.

[0041] Reference Figure 1On the inner wall of the recycling box 1 on both sides of the outer squeezing roller 3, there are steel wire brushes 17 whose bristles are in contact with the squeezing roller 3. Bolts 18 are passed through the steel wire brushes 17. The bolts 18 penetrate the steel wire brushes 17 and are screwed to the inner wall of the recycling box 1. When the squeezing roller 3 rotates, it can generate friction with the bristles of the steel wire brush 17, and the steel wire brush 17 can be used to clean up the garbage adhering to the squeezing roller 3.

[0042] The implementation principle of the present application is as follows: when in use, the user first puts the domestic garbage to be processed into the recycling box 1 through the feed hopper 2, and then starts the motor 4 to drive the two squeezing rollers 3 to rotate towards each other, and uses the squeezing rollers 3 to squeeze and crush the garbage, and squeeze out the residual liquid in the garbage. After being squeezed out, the liquid falls on the screening plate 5 and passes through the screening plate 5 through the water filter hole 6 to flow into the water collecting box 7 below for collection. The dry garbage cannot pass through the water filter hole 6 with a smaller aperture, and slides down along the upper surface of the screening plate 5 to the accommodating chamber 12 set at the bottom of the recycling box 1, thereby realizing the dry and wet separation of the garbage, and avoiding as much as possible the problem that the existing garbage disposal device does not classify the garbage before compression, which easily leads to liquid residue in the garbage after compression, affecting subsequent processing.
