Description

Technical Field

[0001] This utility model relates to the field of waste concrete mortar stripping aggregate recycling technology, specifically to a spiral stripping liner assembly for mortar stripping aggregate recycling. Background Technology

[0002] Recycling aggregates from waste concrete through mortar stripping can reduce dependence on natural sand and gravel resources and is in line with the concept of green and sustainable development. However, mainstream mortar stripping aggregate recycling equipment has not yet been developed in the market. In practice, vertical shaft impact crushers are often used as a substitute, which has several problems: low output, incomplete mortar stripping, over-crushing of aggregates, and high proportion of fine materials. The stripping chamber type in the stripping liner assembly is the key structure of the mortar stripping aggregate recycling equipment. Therefore, how to design a stripping liner assembly that improves both mortar stripping effect and production capacity without over-crushing aggregates and reducing the proportion of fine materials is the problem that this application aims to solve. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a spiral stripping liner assembly for mortar stripping aggregate regeneration that can improve both the stripping effect and production capacity of mortar without over-crushing aggregate and reducing the proportion of fine materials.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A spiral peeling liner assembly for mortar stripping aggregate recycling includes a rotatably arranged moving cone liner and a non-rotatably arranged fixed cone liner. Both the moving cone liner and the fixed cone liner are annular and arranged vertically inside and outside. The outer circumferential surface of the moving cone liner is the moving peeling surface, and the inner circumferential surface of the fixed cone liner is the fixed peeling surface. Several fixed peeling flat teeth are fixedly arranged in a spiral and spaced apart along their circumferential direction on the fixed peeling surface. Several moving peeling flat teeth are fixedly arranged in a spiral and spaced apart along their circumferential direction on the moving peeling surface. A peeling cavity with a gradually decreasing distance from top to bottom is formed between the fixed peeling surface and the moving peeling surface. The peeling cavity is provided with an upper collision chamber, a middle scraping chamber and a lower grinding chamber from top to bottom.

[0005] Furthermore, at least one fixed high tooth for material feeding, which is arranged in a spiral and protrudes from the fixed peeling flat tooth, is fixed on the fixed peeling surface, and at least one movable high tooth for material feeding, which is arranged in a spiral and protrudes from the movable peeling flat tooth, is fixed on the movable peeling surface. Both the fixed high tooth for material feeding and the movable high tooth for material feeding are located in the upper collision chamber and the middle scraping chamber.

[0006] Furthermore, the rotation direction of the fixed peeling flat tooth is the same as that of the fixed material feeding high tooth, the rotation direction of the moving peeling flat tooth is the same as that of the moving material feeding high tooth, and the rotation direction of the fixed peeling flat tooth is opposite to that of the moving peeling flat tooth.

[0007] Furthermore, the helix angles of the fixed peeling flat teeth, the moving peeling flat teeth, the fixed material feeding high teeth, and the moving material feeding high teeth are all 55-65 degrees.

[0008] Furthermore, the cross-sections of the fixed peeling flat teeth, the moving peeling flat teeth, the fixed material-shifting high teeth, and the moving material-shifting high teeth are all arc-shaped.

[0009] Furthermore, the thickness of the fixed feed tooth along the radial direction of the fixed cone liner gradually decreases uniformly from top to bottom, and the thickness of the moving feed tooth along the radial direction of the moving cone liner gradually decreases uniformly from top to bottom.

[0010] Furthermore, the thickness of the fixed peeling flat teeth along the radial direction of the fixed cone liner remains consistent from top to bottom, and the thickness of the moving peeling flat teeth along the radial direction of the moving cone liner remains consistent from top to bottom.

[0011] Furthermore, the fixed peeling teeth are provided with an upper fixed edge, a middle fixed edge, and a lower fixed edge from top to bottom on the side away from the fixed cone liner. The movable peeling teeth are provided with an upper movable edge, a middle movable edge, and a lower movable edge from top to bottom on the side away from the movable cone liner. The upper fixed edge and the upper movable edge are both located in the upper collision chamber, the middle fixed edge and the middle movable edge are both located in the middle scraping chamber, and the lower fixed edge and the lower movable edge are both located in the lower friction chamber.

[0012] Furthermore, the included angles formed between the middle fixed edge and the middle moving edge, the upper fixed edge and the upper moving edge, and the lower fixed edge and the lower moving edge are all the same.

[0013] Furthermore, the fixed peeling surface is a conical surface that is wider at the top and narrower at the bottom, the moving peeling surface is a conical surface that is narrower at the top and wider at the bottom, and the longitudinal section of the peeling cavity is V-shaped on one side.

[0014] As described above, the spiral stripping liner assembly for mortar stripping and aggregate recycling provided by this utility model, driven by the rotation of the moving cone liner and the cooperation of the spirally arranged fixed and moving stripping teeth, allows the waste concrete material to be stripped to pass through the upper collision chamber, the middle scraping chamber, and the lower grinding chamber from top to bottom after entering the stripping chamber. The upper collision chamber has a relatively large spacing, which can accommodate a large number of waste concrete particles side by side. In the upper collision chamber, the collision between materials is more prominent, achieving the initial stripping of mortar from the surface of the waste concrete material. Since the spacing of the middle scraping chamber is smaller than that of the upper collision chamber, the number of waste concrete particles that can be accommodated side by side is also smaller. In the middle scraping chamber, the waste concrete material can come into more contact with the moving stripping teeth. The waste concrete material is scraped and scraped to achieve secondary stripping of the mortar on the surface. Since the spacing of the lower grinding chamber is further reduced compared to the middle scraping chamber, the number of waste concrete particles that can be accommodated side by side is further reduced. In the lower grinding chamber, the waste concrete material can come into more contact with the moving and fixed stripping teeth and be sheared and ground to achieve the final stripping of the mortar on the surface of the waste concrete material and control the discharge particle size. Therefore, the waste concrete material to be stripped will be stripped from top to bottom through the collision between materials, the scraping of the moving stripping teeth, and finally the shearing and grinding of the surface mortar through the smallest discharge port at the bottom of the stripping chamber to complete the stripping and discharge. This can improve the mortar stripping effect and production capacity without excessive crushing of aggregates and reducing the proportion of fine materials. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below through specific embodiments.

[0020] like Figures 1 to 3As shown, the present invention discloses a spiral peeling liner assembly for mortar stripping aggregate recycling, comprising a rotatably arranged movable cone liner 1 and a non-rotatably arranged fixed cone liner 2. Both the movable cone liner 1 and the fixed cone liner 2 are annular in shape and arranged vertically inside and outside. The outer circumferential surface of the movable cone liner 1 is a movable peeling surface 11, and the inner circumferential surface of the fixed cone liner 2 is a fixed peeling surface 21. Several fixed peeling flat teeth 22 are fixedly arranged in a spiral and spaced apart along their circumference on the fixed peeling surface 21. Several movable peeling flat teeth 12 are fixedly arranged in a spiral and spaced apart along their circumference on the movable peeling surface 11. A peeling cavity 3 is formed between the fixed peeling surface 21 and the movable peeling surface 11, with the spacing gradually decreasing from top to bottom. The peeling cavity 3 is provided with an upper collision chamber 31, a middle scraping chamber 32, and a lower grinding chamber 33 in sequence from top to bottom.

[0021] Driven by the rotation of the moving cone liner 1, and with the cooperation of the spirally arranged fixed peeling teeth 22 and the moving peeling teeth 12, when the waste concrete material to be peeled enters the peeling chamber 3, it will pass through the upper collision chamber 31, the middle scraping chamber 32, and the lower grinding chamber 33 from top to bottom. The upper collision chamber 31 has a relatively large spacing, which can accommodate a large number of waste concrete particles side by side. In the upper collision chamber 31, the collision between materials is more prominent, so as to achieve the initial peeling of the mortar on the surface of the waste concrete material. Since the spacing of the middle scraping chamber 32 is smaller than that of the upper collision chamber 31, the number of waste concrete particles that can be accommodated side by side is also smaller. In the middle scraping chamber 32, the waste concrete material can come into more contact with the moving peeling teeth 12 and be scraped, so as to achieve the initial peeling of the mortar on the surface of the waste concrete material. The secondary stripping of mortar from the surface of waste concrete material is achieved. Since the spacing of the lower grinding chamber 33 is further reduced compared to the spacing of the middle scraping chamber 32, the number of waste concrete material particles that can be accommodated side by side is further reduced. In the lower grinding chamber 33, the waste concrete material can come into more contact with the moving stripping teeth 12 and the fixed stripping teeth 22 and be sheared and ground to achieve the final stripping of mortar from the surface of the waste concrete material and control the discharge particle size. Therefore, the waste concrete material to be stripped will be stripped from top to bottom through the collision between materials, the scraping of the moving stripping teeth 12, and finally through the smallest discharge port at the bottom of the stripping chamber 3 to remove the surface mortar and complete the stripping and discharge. This can improve the mortar stripping effect and production capacity without excessive crushing of aggregates and reducing the proportion of fine materials.

[0022] In addition, at least one fixed material-pushing tooth 23, which is spirally arranged and protrudes from the fixed peeling flat tooth 22, is fixedly provided on the fixed peeling surface 21. At least one movable material-pushing tooth 13, which is spirally arranged and protrudes from the movable peeling flat tooth 12, is also fixedly provided on the movable peeling surface 11. The fixed material-pushing tooth 23 and the movable material-pushing tooth 13 are both located in the upper collision chamber 31 and the middle scraping chamber 32. The fixed material-pushing tooth 23 and the movable material-pushing tooth 13 can play a certain material-pushing effect in the upper collision chamber 31 and the middle scraping chamber 32, thereby having a certain anti-blocking function. At the same time, they can better move the material, which is conducive to improving the collision effect between materials in the upper collision chamber 31 and the rotational scraping effect in the middle scraping chamber 32. Preferably, the number of fixed material-pushing teeth 23 and movable material-pushing teeth 13 is 1-15.

[0023] The rotation direction of the fixed material feeding high tooth 23 is the same as that of the fixed peeling flat tooth 22, the rotation direction of the moving material feeding high tooth 13 is the same as that of the moving peeling flat tooth 12, and the rotation direction of the fixed peeling flat tooth 22 is opposite to that of the moving peeling flat tooth 12.

[0024] The helix angles of the fixed peeling flat tooth 22, the moving peeling flat tooth 12, the fixed material feeding high tooth 23, and the moving material feeding high tooth 13 are all 55-65 degrees.

[0025] The cross-sections of the fixed peeling flat tooth 22, the moving peeling flat tooth 12, the fixed material-pulling high tooth 23, and the moving material-pulling high tooth 13 are all arc-shaped.

[0026] Preferably, the thickness of the fixed material-dispensing tooth 23 along the radial direction of the fixed cone liner 2 gradually decreases uniformly from top to bottom, and the thickness of the movable material-dispensing tooth 13 along the radial direction of the movable cone liner 1 gradually decreases uniformly from top to bottom. The material-dispensing effect of the fixed material-dispensing tooth 23 and the movable material-dispensing tooth 13 will gradually weaken from top to bottom. That is, the material-dispensing effect of the fixed material-dispensing tooth 23 and the movable material-dispensing tooth 13 in the upper collision chamber 31 is greater than the material-dispensing effect in the middle scraping chamber 32.

[0027] The thickness of the fixed peeling flat tooth 22 along the radial direction of the fixed cone liner 2 remains consistent from top to bottom, and the thickness of the movable peeling flat tooth 12 along the radial direction of the movable cone liner 1 remains consistent from top to bottom.

[0028] The fixed peeling teeth 22 are provided with an upper fixed edge 221, a middle fixed edge 222, and a lower fixed edge 223 from top to bottom on the side away from the fixed cone liner 2. The movable peeling teeth 12 are provided with an upper movable edge 121, a middle movable edge 122, and a lower movable edge 123 from top to bottom on the side away from the movable cone liner 1. The upper fixed edge 221 and the upper movable edge 121 are both located in the upper collision chamber 31. The middle fixed edge 222 and the middle movable edge 122 are both located in the middle scraping chamber 32. The lower fixed edge 223 and the lower movable edge 123 are both located in the lower grinding chamber 33. The upper fixed edge 221, the middle fixed edge 222, the lower fixed edge 223, the upper movable edge 121, the middle movable edge 122, and the lower movable edge 123 can all scrape and peel the mortar on the aggregate surface.

[0029] The angles formed between the fixed edge 222 and the moving edge 122, the angles formed between the upper fixed edge 221 and the upper moving edge 121, and the angles formed between the lower fixed edge 223 and the lower moving edge 123 are all the same.

[0030] The fixed peeling surface 21 is a conical surface that is wider at the top and narrower at the bottom, and the moving peeling surface 11 is a conical surface that is narrower at the top and wider at the bottom. The longitudinal section of the peeling cavity 3 is V-shaped on one side. It is a standard cavity type, which can increase the grinding and scraping time of aggregates. It is suitable for waste concrete with lower grade, which can reduce the crushing of raw stones and increase the yield.

[0031] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
