Technical Field

[0001] This utility model belongs to the field of waste treatment technology, and relates to waste separation and treatment, particularly a household waste screening device. Background Technology

[0002] Household waste refers to various solid wastes generated in daily life, typically including waste from households, businesses, and public places. Household waste is diverse, highlighting the importance of waste sorting. Sorting household waste helps improve resource recycling rates, reduce waste, alleviate waste disposal pressure, lower environmental pollution levels, promote public environmental awareness, and drive sustainable development.

[0003] A search revealed a Chinese patent document disclosing a household waste screening device [Application No.: CN202421134578.1; Publication No.: CN222369542U]. This household waste screening device includes a screening box, a receiving frame inside the screening box, a screening mechanism on the upper part of the receiving frame, a drive mechanism connected to the screening mechanism, and a feed inlet on the top of the screening box. The screening mechanism includes two relatively rotating screening rollers, each with several screening rods arranged in a circular array. Partitions are provided on both sides below the screening rollers. There are three receiving frames located between the two partitions. An isolation plate inclined upwards towards the center is provided above the partitions, and the isolation plate has clearance grooves for the screening rods.

[0004] Although the household waste screening device disclosed in this patent is convenient for screening household waste and is easy to operate, it is difficult to process the waste later because there are many types of household waste and some water stains inside the waste. In addition, it is not convenient to separate the different sizes and types of waste. Therefore, it is necessary to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a household waste screening device. The technical problem this utility model aims to solve is: how to remove water stains from waste while separating waste of different sizes.

[0027] like Figure 1 - Figure 4 As shown, a municipal solid waste screening device includes a processing box 1. A feed inlet 17 is provided at one end of the surface of the processing box 1. A receiving box 2 is fixedly connected to the surface of the processing box 1 near the feed inlet 17. The bottom of the receiving box 2 is inclined. A filter barrel 3, a first screening cylinder 32, and a second screening cylinder 34 are rotatably connected inside the processing box 1. The filter barrel 3, the first screening cylinder 32, and the second screening cylinder 34 are fixedly connected to each other. The processing box 1 is equipped with a rotating mechanism for rotating the filter barrel 3, the first screening cylinder 32, and the second screening cylinder 34. Threaded conveying rods 37 are fixedly connected to the inner walls of the filter barrel 3, the first screening cylinder 32, and the second screening cylinder 34. By rotating the filter barrel 3, the first screening cylinder 32, and the second screening cylinder 34 during use, the waste inside can be dehydrated and separated, thereby improving the effectiveness of the device.

[0028] In this utility model, the rotating mechanism includes a connecting ring 36. Two partitions 16 are vertically fixedly connected inside the processing box 1. The filter barrel 3, the first screening cylinder 32, and the second screening cylinder 34 are rotatably sleeved inside the two partitions 16. There are four connecting rings 36, which are rotatably sleeved on the surfaces of the filter barrel 3, the first screening cylinder 32, and the second screening cylinder 34, respectively. Two connecting rings 36 are fixedly connected to the symmetrical ends inside the processing box 1, and the other two connecting rings 36 are sleeved inside the two partitions 16. A motor 4 is installed on the surface of the processing box 1 away from the receiving box 2. The end of the second screening cylinder 34 away from the filter barrel 3 is sealed. The output end of the motor 4 is fixedly connected to the center of one end of the second screening cylinder 34, which is used to rotate the filter barrel 3, the first screening cylinder 32, and the second screening cylinder 34. With the help of the threaded conveying rod 37, the internal waste is transported.

[0029] In this utility model, two other connecting rings 36 are respectively set at both ends of the first screening cylinder 32. The surface of the filter barrel 3 is provided with multiple water leakage holes 31. The inside of the treatment box 1 is fixedly connected to a second guide plate 19, which is inclined. A sewage outlet 14 is opened on one side of the surface of the treatment box 1. The sewage outlet 14 is located at the lower end of the second guide plate 19. A sewage tank 15 is fixedly connected to one side of the surface of the treatment box 1. The sewage tank 15 is located on the surface of the sewage outlet 14 and is used to dehydrate the garbage inside the filter barrel 3 so that the water in the garbage can be leaked out through the water leakage holes 31.

[0030] The surface of the first screening cylinder 32 is provided with multiple first leakage holes 33, and the surface of the second screening cylinder 34 is provided with multiple second leakage holes 35. The first screening cylinder 32 is located between two partitions 16. Two first guide plates 18 are fixedly connected inside the processing box 1. The two first guide plates 18 are respectively located on one side of the two partitions 16. The two partitions 16 are respectively located at the bottom of the first screening cylinder 32 and the second screening cylinder 34. Two discharge ports 11 are opened on the other side of the surface of the processing box 1. The two discharge ports 11 are respectively located at the lower end of the two first guide plates 18. A collection box 12 is fixedly connected to the other side of the surface of the processing box 1. The collection box 12 is provided with two collection troughs 13 inside. The two collection troughs 13 correspond to the two discharge ports 11 respectively, so that waste of different sizes can be discharged through the first leakage holes 33 on the surface of the first screening cylinder 32 or the second leakage holes 35 on the surface of the second screening cylinder 34, thereby separating and collecting the waste.

[0031] In this invention, a support frame 21 is fixedly connected to the bottom of the receiving box 2. The support frame 21 is fixedly connected to the surface of the processing box 1 to support the receiving box 2, making the device more stable in use.

[0032] The working principle of this utility model is as follows: When in use, the waste to be processed can be placed inside the receiving box 2. Then, the drive motor 4 drives the second screening cylinder 34, the first screening cylinder 32, and the filter barrel 3 to rotate simultaneously. At this time, the threaded conveyor rod 37 causes the waste inside the receiving box 2 to slide downwards into the filter barrel 3, where it is then conveyed. Multiple drainage holes 31 cause water in the waste to leak downwards, flowing through the second guide plate 19 to the sewage tank 15 for collection. The waste then slides into the first screening cylinder 32, passing through multiple first drainage holes 33, causing smaller pieces of waste to leak downwards. These smaller pieces then slide through one of the first guide plates 18 into one of the collection troughs 13. The remaining waste slides into the second screening cylinder 34, leaks downwards through multiple second drainage holes 35, and then slides through another first guide plate 18 into another collection trough 13 for collection, thus enabling waste sorting.

[0033] In summary, in this utility model, by setting up the filter barrel 3, the first screening cylinder 32 and the second screening cylinder 34, the filter barrel 3, the first screening cylinder 32 and the second screening cylinder 34 can be rotated during use, so as to dehydrate and separate the garbage inside, thereby improving the use effect of the device.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
