Description

Technical Field

[0001] This utility model relates to the technical field of sand and gravel separation equipment, specifically a concrete sand and gravel separation device. Background Technology

[0002] Concrete aggregate separators are used to receive mud and water from mixer trucks and separate sand and gravel from the mud and water, allowing them to be reused as raw materials for concrete mixing, thus achieving resource recycling. Aggregate separators include vibrating screens and drum screens. Existing drum screen aggregate separators have a feed hopper at the input end of the drum screen, which directly guides the mud and water to the inner center of the drum screen. The rotation of the drum screen filters out the sand and mud, while the gravel remains inside. However, the direct delivery of mud and water to the inner center of the drum screen causes it to accumulate, preventing the drum screen from effectively screening sand and mud, thus affecting separation efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a concrete sand and gravel separation device to address the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: A concrete aggregate separation device includes: a frame, a drum screen, a feed hopper, a sand discharge hopper, a gravel discharge hopper, and a drive mechanism. The drum screen is rotatably mounted on the frame and is arranged at an angle. The drive mechanism is used to drive the drum screen to rotate. The feed hopper is located on the upper part of the frame, and an arc-shaped guide section is provided at the lower part of the feed hopper. The arc-shaped guide section extends from the upper end of the drum screen into the interior of the drum screen, and the outlet of the arc-shaped guide section is close to the side wall of the drum screen, and the outlet direction of the arc-shaped guide section is tangent to the side wall of the drum screen. Both the sand discharge hopper and the gravel discharge hopper are located at the lower part of the frame, with the sand discharge hopper located below the drum screen and the gravel discharge hopper located below the lower end of the drum screen.

[0005] Furthermore, the frame is provided with a striking mechanism, which includes a mounting frame, a rotating shaft, and flexible strips. The mounting frame is mounted on the frame, the rotating shaft is rotatably mounted on the mounting frame, and a plurality of flexible strips are provided on the rotating shaft. The driving mechanism is also used to drive the rotating shaft to rotate.

[0006] Furthermore, a first pulley is provided on the shaft of the drum screen, and a second pulley is provided on the rotating shaft. The first pulley and the second pulley are connected by a belt.

[0007] Furthermore, a cylindrical cover is provided on the frame, which covers the outside of the drum screen.

[0008] Furthermore, a baffle is provided between the sand discharge hopper and the stone discharge hopper.

[0009] Furthermore, the drive mechanism includes a motor, a reducer, and a coupling. The motor and the reducer are both mounted on the frame. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the shaft of the drum screen via the coupling.

[0010] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The feed hopper of this application is provided with an arc-shaped discharge section at the bottom, and the outlet of the arc-shaped discharge section extends to the inner side wall of the drum screen to guide the mud and water to the side wall of the drum screen. After being discharged, the sand and mud will move along the side wall of the drum screen under the action of gravity, so that the sand, mud and stones are spread out. Then, under the action of the rotation of the drum screen, they pass through the screen holes, thereby achieving the purpose of separating sand and mud, improving separation efficiency, and preventing sand and mud from accumulating and clumping in the middle of the inner side of the drum screen.

[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0017] The frame 1 is provided with at least two bearing seats. The shaft 21 of the drum screen 2 is rotatably mounted on the frame 1 through the bearing seats, and the drum screen 2 is set at an angle.

[0018] The drive mechanism 6 is mounted on the frame 1 and is located on the upper side of the drum screen 2. The drive mechanism 6 includes a motor 61, a reducer 62 and a coupling 63. The motor 61 and the reducer 62 are both mounted on the frame 1. The output end of the motor 61 is connected to the input end of the reducer 62. The output end of the reducer 62 is connected to the shaft 21 of the drum screen 2 through the coupling 63. The motor 61 can drive the drum screen 2 to rotate.

[0019] like Figure 2 As shown, the feed hopper 3 is located on the upper part of the frame 1, and the lower part of the feed hopper 3 is provided with an arc-shaped guide section 31. The arc-shaped guide section 31 extends from the upper end of the drum screen 2 into the interior of the drum screen 2, and the outlet of the arc-shaped guide section 31 is close to the side wall of the drum screen 2, and the outlet direction of the arc-shaped guide section 31 is tangential to the side wall of the drum screen 2. When mud and water are fed into the feed hopper 3, the mud and water will move along the arc-shaped guide section 31 to the inner side wall of the upper end of the drum screen 2, and enter the drum screen 2 tangentially from the inner side wall. Sand, mud, and stones will move along the inner side wall of the drum screen 2 under the action of gravity to spread out, such as... Figure 2 As indicated by the hollow arrow.

[0020] The sand discharge hopper 4 and the gravel discharge hopper 5 are located at the lower part of the frame 1.

The baffle 8 is used to fill the gap between the sand discharge hopper 4, the stone discharge hopper 5 and the drum screen 2 to prevent stones from rebounding in the stone discharge hopper 5 and entering the sand discharge hopper 4.

[0022] Specifically, the sand and mud discharged from the sand discharge hopper 4 can be separated into sand and mud water by a spiral sand washing machine; the stones discharged from the stone discharge hopper 5 will have some sand and mud residue on their surface, which can be washed to clean the residue on the stone surface.

[0023] Example 2 This embodiment is an improvement on embodiment 1, the improvement being the addition of a tapping mechanism.

[0024] To prevent sand or mud from clogging the screen holes of the drum screen 2, a tapping mechanism 7 is installed on the frame 1. The tapping mechanism 7 can intermittently tap the drum screen 2 to make the drum screen 2 vibrate, thereby shaking the sand and mud out of the screen holes.
