DETAILED DESCRIPTION

[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0045] In order to save energy, Figure 1-5 As shown, the slurry screening device for preparing recycled concrete described in the utility model comprises:

[0046] Conveying unit 1;

[0047] The primary screening part 2 is arranged at the discharge end of the conveying part 1;

[0048] The fine screen part 3 is arranged at the discharge end of the primary screen part 2;

[0049] The driving part 4 is arranged on the fine screen part 3 .

[0050] The level of the feed end of the fine screen part 3 is higher than the level of the discharge end.

[0051] When in use, a set of slurry screening mechanisms is provided for the preparation of recycled concrete through the conveying part 1, the primary screening part 2, the fine screening part 3 and the driving part 4, so that the slurry and large and small aggregates in the concrete can be finely screened, which helps the personnel to use aggregates of different sizes according to the application requirements of different building materials and projects in the later stage, thereby improving the utilization rate of recycled concrete and having a good energy-saving effect.

[0052] For example, Figure 2 As shown, the utility model also includes that the conveying part 1 includes:

[0053] A first bracket 101;

[0054] The conveyor 102 is arranged on the first bracket 101;

[0055] The hopper 103 is disposed at the feeding end of the conveyor 102 and connected to the first bracket 101 .

[0056] When in use, the concrete material to be screened is delivered to the hopper 103 , and the conveyor 102 transports the concrete material to the primary screening part 2 .

[0057] To screen the slurry, for example, Figure 3 As shown, the utility model also includes that the primary screening unit 2 includes:

[0058] A second bracket 201;

[0059] The vibrating screen 202 is disposed on the second bracket 201 .

[0060] When in use, the vibrating screen 202 of the primary screening part 2 vibrates the incoming concrete to screen the material. As the vibrating screen 202 vibrates, the slurry in the concrete will leak out and be collected by a container below the vibrating screen 202, or a pumping pipeline is connected to the discharge port of the vibrating screen 202 to send the screened slurry to the nearest liquid collection tank. As the vibrating screen 202 vibrates and feeds the material, the solid material in the concrete will be sent to the fine screen part 3. During this period, the length of the vibrating screen 202 used is selected according to the actual screening needs.

[0061] For fine screening of concrete material, for example, Figure 4 , 5 As shown, the utility model also includes that the fine screen part 3 includes:

[0062] A third bracket 301;

[0063] The circular frame 302 is provided in at least one group and is arranged on the third bracket 301;

[0064] A main shaft 303 is disposed on the circular frame 302;

[0065] The screen bars 304 are provided in at least one group and are arranged on the circular frame 302;

[0066] At least one set of discharge plates 305 is provided and is disposed on the third bracket 301 .

[0067] When in use, the screen bars 304 on the fine screen part 3 screen the incoming concrete solids.

[0068] For example, Figure 5 As shown, the utility model also includes that the driving unit 4 includes:

[0069] The motor frame 401 is arranged on the third frame 301;

[0070] The motor 402 is arranged on the motor frame 401;

[0071] The commutator 403 is arranged on the motor frame 401;

[0072] The sprockets 404 are provided in two groups.

[0073] When in use, the driving unit 4 drives the main shaft 303 to rotate, so that the fine screen unit 3 screens the continuously entering concrete solids in a rotating state.

[0074] The circular frames 302 at both ends of the fine screen part 3 are rotatably connected to the third bracket 301 through a bearing seat. A triangular support member 306 is arranged in the circular frame 302 , and the center of the triangular support member 306 is fixed to the main shaft 303 .

[0075] The screen bars 304 are arranged between the circular frames 302 and are arranged at equal distances along the circumference of the circular frames 302. Both ends of the screen bars 304 are welded to the adjacent circular frames 302. The number of screen bars on each group of the circular frames 302 gradually decreases.

[0076] The driving end of the motor 402 is connected to the input end of the commutator 403 , and the two groups of sprockets 404 are respectively arranged on the output end of the commutator 403 and the shaft head of the main shaft 303 , and the two groups of sprockets 404 are connected through a transmission chain.

[0077] When the utility model is in use, the concrete material to be screened is sent to the hopper 103, and the concrete material is transported to the primary screening part 2 by the conveyor 102. The vibrating screen 202 of the primary screening part 2 vibrates and screens the entered concrete. With the vibration of the vibrating screen 202, the slurry in the concrete will leak out and be discharged. The liquid is collected under the vibrating screen 202 through a container, or a pumping pipeline is connected to the discharge port of the vibrating screen 202 to send the screened slurry to the nearest liquid collecting tank. With the vibration and feeding of the vibrating screen 202, the solid material in the concrete will be sent to the fine screen part 3 to achieve primary screening.

[0078] The commutator 403 is driven by the motor 402, and the sprocket 404 on the commutator 403 drives the sprocket 404 of the main shaft 303 to rotate, so that the main shaft 303 drives the circular frame 302 and the screen bars 304 to rotate, and the concrete is gradually discharged from the feeding end of the fine screen part 3 to the discharging end of the fine screen part 3 based on the height difference between the two ends of the fine screen part 3 and the rotational force. During this period, the concrete solids will be gradually discharged from the end of the fine screen part 3 where the screen bars 304 are densely arranged to the end where the screen bars 304 are sparsely arranged, and the densely arranged screen bars 304 will screen out small particles of solids in the concrete solids, and the sparsely arranged screen bars 304 will screen out large particles of solids, until the larger particle size of solids in the solids is discharged from the tail end of the fine screen part 3, and the aggregates of different particle sizes are discharged by the discharge plates 305 at different positions, thereby completing the screening operation of recycled concrete.
