Description

Technical Field

[0001] The utility model relates to the field of concrete recycling equipment, in particular to a system for recycling surplus concrete from a mixing station to prepare small components. Background Art

[0002] During the construction process, when pouring large volumes of concrete, the amount of concrete prepared by the mixing station is generally surplus to actual demand. Treating it as waste will result in a large waste of resources and is not in line with the concept of green construction.

[0003] Since it usually takes a short time for concrete to begin to lose its plasticity and components cannot be prepared after initial setting, it is difficult to transport it to other locations for other uses.

[0004] In view of the shortcomings of the existing technology, it is urgent to design a system for recycling excess concrete to prepare small components. Utility Model Content

[0005] The utility model aims to overcome the deficiencies in the prior art and provide a system for recycling surplus concrete from a mixing station to prepare small components.

[0007] A material separator is connected below the top opening of the material separation workshop, a fine material port is provided below the material separator, a small-sized aggregate and slurry collector is provided below the fine material port, a slurry delivery pipeline is provided on one side of the bottom of the small-sized aggregate and slurry collector, and the slurry delivery pipeline extends to the small component prefabrication workshop.

[0009] Preferably, a large-sized coarse aggregate collector is connected to the outer side of the coarse material outlet, and an opening is provided at the bottom of the material separation workshop corresponding to the large-sized coarse aggregate collector.

[0010] Preferably, the small-sized aggregate and slurry collector comprises a collector shell, the top of which is open and covered with a flexible filter screen, the cross-sectional shape of the collector shell is an inverted right-angled trapezoid, and the hypotenuse of the inverted right-angled trapezoid is opposite to the side where the slurry delivery pipeline is located.

[0011] Preferably, the mesh shape of the flexible filter is square, the mesh shape of the rigid filter is circular, and the diameter of the rigid filter mesh is equal to the side length of the flexible filter mesh.

DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the embodiments. The description of the following embodiments is only used to help understand the utility model. It should be pointed out that for ordinary people in this technical field, the utility model can also be modified in some ways without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.

[0027] As an example, Figures 1 to 8 As shown, the system for recycling the remaining concrete in the mixing station to prepare small components includes: a raw material bucket 1, a lifting and unloading device 2, a material separation workshop 4 and a small component prefabrication workshop 5. The material separation workshop 4 is provided with an opening at the top, and the lifting and unloading device 2 is arranged on one side of the material separation workshop 4. The lifting and unloading device 2 includes a steel frame 21, a lifting rope 22 and a winch 23. The winch 23 is fixed on the top of the steel frame 21. The winch 23 is connected to the raw material bucket 1 through the lifting rope 22, and the raw material bucket 1 moves up and down in the steel frame 21.

[0028] like Figure 2 and Figure 3 As shown, the raw material hopper 1 is provided with a discharge port 12 on the side facing the material separation workshop 4, and an anchor head 13 is provided on the top; a discharge guide trough 3 extending to the top opening of the material separation workshop 4 is set up at a certain height of the lifting and unloading device 2; after the discharge port 12 of the raw material hopper 1 is opened, the concrete inside falls into the discharge guide trough 3 and finally slides into the material separation workshop 4.

[0029] like Figures 4 to 6As shown, a material separator 42, a large-size coarse aggregate collector 43, and a small-size aggregate and slurry collector 44 are arranged in the factory building 41 of the material separation workshop 4. The material separator 42 is connected to the bottom of the top opening of the material separation workshop 4. The cross-sectional shape of the material separator 42 is a right-angled triangle. One right-angled side of the right-angled triangle corresponds to the top opening of the material separation workshop 4, and the other right-angled side is vertically downward and is provided with a coarse material port 424. The large-size coarse aggregate collector 43 is connected to the outside of the coarse material port 424. The material separation workshop 4 is provided with an opening at the bottom corresponding to the large-size coarse aggregate collector 43.

[0030] One side of the hypotenuse of the right triangle is a fine material opening 421, and the fine material opening 421 is covered with a rigid filter screen 422, such as Figure 8 As shown, the mesh shape of the rigid filter 422 is circular, and the diameter is determined according to the size of the prefabricated component. A small-sized aggregate and slurry collector 44 is provided below the fine material port 421. The small-sized aggregate and slurry collector 44 includes a collector housing 442. The top of the collector housing 442 is open and covered with a flexible filter 443, which can effectively avoid the impact force of the small-sized aggregate when it hits, forming a buffer. Figure 7 As shown, the mesh shape of the flexible filter screen 443 is square, and the diameter of the mesh of the rigid filter screen 422 is equal to the side length of the mesh of the flexible filter screen 443, which is used for secondary screening of large-sized coarse aggregates.

[0031] A slurry delivery pipeline 444 is provided at one side of the bottom of the small-sized aggregate and slurry collector 44, and the slurry delivery pipeline 444 extends to the small-sized component prefabrication workshop 5. The cross-sectional shape of the collector housing 442 is an inverted right-angled trapezoid, the hypotenuse of the inverted right-angled trapezoid is opposite to the side where the slurry delivery pipeline 444 is located, and the hypotenuse of the inverted right-angled trapezoid is located directly below the fine material port 421, so that the small-sized aggregate and cement mortar flowing out of the material separator 42 first impact on the hypotenuse of the inverted right-angled trapezoid after entering the small-sized aggregate and slurry collector 44, and then slide down along the hypotenuse to one side of the slurry delivery pipeline 444, which is more conducive to the small-sized aggregate and slurry inside the small-sized aggregate and slurry collector 44 being transported away by the slurry delivery pipeline 444.

[0032] When a certain amount of commercial concrete remains after pouring of large-volume concrete at the construction site, and there is no other use, the remaining part can be dumped into the raw material bucket 1 of the device, and the lifting and unloading device 2 lifts the raw material bucket 1 filled with concrete to a certain height and then unloads the material, and the concrete falls into the unloading guide trough 3, and preliminary material separation occurs during the collision process. The partially separated concrete enters the material separator 42 of the material separation workshop 4 along the unloading guide trough 3, and the small-size aggregate and cement mortar are double filtered through the rigid filter 422 and the flexible filter 443, and enter the small prefabricated component workshop 5 through the slurry conveying pipeline 444 to prepare prefabricated components. The separated large-particle aggregate cannot be used to prepare small-size components, and can be washed and reused, or treated as waste.
