Description

Technical Field

[0001] The utility model relates to the technical field of material screening, in particular to a novel spiral screen for garbage sorting. Background Art

[0002] With the acceleration of urbanization, the amount of construction waste generated and discharged in cities is also growing rapidly. Recycling construction waste is an important part of environmental protection. There are many types of materials in construction waste, including bricks, cement blocks, lightweight garbage, etc. Different types of materials have different particle sizes.

[0003] Screening construction waste of different particle sizes to achieve different treatments. When screening construction waste, the existing "a vibrating screening machine" with application number 201310065758.9 and "a vibrating screener" with application number 201410236536.3 are used. The screen plate is set to an inclined shape, screening holes are set on the screen plate, and the screen plate is driven to vibrate by a vibration motor to achieve material sorting.

[0004] In order to better realize the recycling of construction waste, the finer the classification of construction waste, the more thorough its utilization. However, with the existing screening structure, it can only classify construction waste into two categories according to the size of the sieve holes on the sieve plate, that is, construction waste smaller than the sieve hole size is screened into the first category, and construction waste larger than the sieve hole size is screened into the second category. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provide a novel spiral screen for garbage sorting, which can classify construction waste into three categories for output, thereby realizing refined construction waste classification.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] The utility model provides a new type of spiral screen for garbage sorting, comprising:

[0008] A screening box, the screening box comprising a box body, a screen plate arranged in the box body, a first discharge port arranged at one end of the screen plate, and a second discharge port arranged at one side of the screen plate;

[0009] A material conveying assembly, the material conveying assembly comprising at least two spiral shafts disposed above the sieve plate and arranged in parallel, one end of the spiral shaft being disposed on one side of the first discharge port, the spiral shaft comprising a rotating shaft and a spiral sheet wound on the rotating shaft;

[0010] A driving assembly is connected to the feeding assembly to drive the feeding assembly to rotate.

[0011] The utility model has the following advantages:

[0012] The utility model adopts a sieve plate and a spiral shaft structure to realize the classification of construction waste. The sieve plate can screen out light waste with a particle size smaller than the sieve hole. Under the action of the spiral sheet, part of the construction waste is driven to move to the side of the second discharge port and enter the second discharge port. While the spiral shaft rotates, under the action of rolling friction, part of the construction waste is pushed to move to the first discharge port. That is, by adopting the above structure, the construction waste can be classified into three categories for output, thereby realizing more refined construction waste classification, which is conducive to improving the thoroughness of construction waste utilization.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The utility model discloses a new type of spiral screen for garbage sorting, which can sort construction waste into three categories for output. Specifically, Figures 1 to 3 As shown, the screening device includes a screening box, a material feeding component and a driving component 3.

[0024] The screening box includes a box body 11, a sieve plate arranged in the box body 11, a first discharge port 12 arranged at one end of the sieve plate, and a second discharge port 13 arranged at one side of the sieve plate, wherein the aperture of the sieve holes on the sieve plate is set according to the specific particle size to be screened. The feeding assembly includes at least two spiral shafts 2 arranged above the sieve plate and in parallel, one end of the spiral shaft is placed on one side of the first discharge port 12, and the spiral shaft 2 includes a rotating shaft 21 and a spiral sheet 22 wound on the rotating shaft; the driving assembly is connected to the feeding assembly to drive the feeding assembly to rotate.

[0025] With the above structure, construction waste enters the box body 11 through the end of the spiral shaft 2 away from the first discharge port 12. Under the action of the spiral shaft 2, some small-particle construction waste falls below the spiral shaft 2, and the remaining large-particle construction waste is placed above the spiral shaft 2, such as bricks and stones with larger particle sizes or plastic boards, plastic bags and other materials that cannot fall. The driving component drives the spiral shaft 2 to rotate toward the second discharge port 13. During the rotation, the large-particle construction waste moves toward the second discharge port 13 under the action of the spiral blade and then enters the second discharge port 13. The small-particle construction waste that falls below the spiral shaft 2 and is smaller than the sieve hole diameter of the sieve plate falls, and the construction waste that is larger than the sieve hole diameter of the sieve plate moves toward the first discharge port 12 under the action of the spiral shaft 2 and then enters the first discharge port 12.

[0026] In order to facilitate the recycling of garbage, a third collecting hopper 14 is provided below the screen plate.

[0027] In order to facilitate the recycling of garbage, a first discharge hopper 15 is provided below the first discharge port 12 , and / or a second discharge hopper 16 is provided below the second discharge port 13 .

[0028] The drive assembly 3 realizes the rotation drive of the screw shaft 2. There are many ways to realize it. In order to simplify the device structure, it exemplarily includes a drive motor 31 and a transmission gear assembly connected to the drive motor 31. The transmission gear assembly is arranged on the screw shaft 2. The number of gears in the transmission gear assembly and its specific connection structure are conventional technologies, which are not described in detail in this solution. With the transmission gear assembly structure, one drive motor can drive multiple screw shafts 2, simplifying the device structure.

[0029] On the basis of the above structure, in order to prevent the lubricating oil on the transmission gear assembly from dripping everywhere, an oil collecting tank 33 is arranged on the screening box below the transmission gear assembly.

[0030] In order to enhance the protection of the transmission gear assembly and avoid the influence of construction waste on the assembly during the screening process, a cavity is provided on the screening box for placing the transmission gear assembly to achieve isolation of the transmission gear assembly from the screen plate and the screw shaft 2. In order to facilitate the maintenance of the transmission gear assembly, an opening and closing door structure 17 is provided above the cavity.

[0031] For example, Figure 2 As shown, multiple screw shafts 2 are provided, and two sets of drive components 3 are used to achieve driving. When the above structure is adopted, the inlet of the construction waste is preferably arranged as follows Figure 3 Upper left position shown.

[0032] The particle size of the construction waste screened out through the second discharge port 13 is determined by the distance between two adjacent spiral shafts 2. To this end, the distance between two adjacent spiral shafts 2 can be adjusted according to specific screening requirements. On this basis, in order to achieve reliable screening of construction waste, the distance between the two adjacent rotating shafts 21 is less than twice the outer diameter of the spiral blade 22, that is, Figure 2 As shown, the spiral pieces 22 of two adjacent spiral shafts 2 in the axial direction partially overlap. With the above structure, the ability of the spiral shaft 2 to screen large particles of construction waste can be enhanced.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
