[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-5 As one embodiment of this utility model, a solid-liquid separation device for concrete waste is disclosed. The separation device includes a frame 1 and a drum screen 3 rotatably connected above the frame 1 via a drive device 2. The drum screen 3 has open ends. By setting the two ends of the drum screen 3 to be open, a waste inlet and a stone outlet are formed. When the waste enters the drum screen 3 for conveying, the drum screen 3 separates the waste. The stone is discharged from the stone outlet of the drum screen 3, while water and sand fall below through the drum screen 3 to complete the initial separation.

[0029] Specifically, the drum screen 3 described in this embodiment includes a screen frame and auger blades installed in the screen frame. Both ends of the drum screen 3 are rotatably connected to the upper part of the frame 1 via support shafts. The drive device 2 described herein is a motor, which can drive the drum screen 3 to rotate and transport concrete waste via pulleys and synchronous belt assemblies or chain and sprocket assemblies. This method is conventional for those skilled in the art and will not be elaborated upon here.

[0030] Furthermore, in this embodiment, two guide plates 4 are fixedly installed at the bottom of the frame 1, and a water-sand separation component 5 is rotatably connected below the frame 1. The water-sand separation component 5 is used to achieve secondary separation of water and sand, so as to achieve complete separation of stone, sand and water in the waste. The water-sand separation component 5 is located below the two guide plates 4, and the water-sand separation component 5 is connected to the frame 1 through an elastic mechanism 6.

[0031] In some embodiments, the water-sand separation component 5 of the present invention includes a separation frame 51; one end of the separation frame 51 is connected to the frame 1 by a pin, and the other end is connected to the frame 1 by an elastic mechanism 6. The separation frame 51 is inclined in the initial state, and a sand outlet 52 is provided at the bottom end in the inclined direction for discharging sand.

[0032] Based on the above embodiments, in this embodiment, two guide plates 53 are fixedly installed inside the separation frame 51, and a filter screen 54 is movably inserted between the two guide plates 53. In this embodiment, the filter screen 54 can be set as a stainless steel filter screen, and the movable insertion method can facilitate the replacement of the filter screen 54.

[0033] The separation frame 51 is detachably connected to a baffle plate 55 at the front end of the filter screen 54. The baffle plate 55 is designed to prevent water from being discharged from the sand outlet. In this embodiment, a part of the baffle plate 55 stops the front side of the filter screen 54 to achieve the installation and positioning of the filter screen 54. That is, when the filter screen 54 needs to be replaced, only the baffle plate 55 needs to be removed to pull the filter screen 54 out of the guide plate 53 for maintenance.

[0034] Optionally, in this embodiment, at least two insert rods 56 are fixedly installed at the bottom of the baffle plate 55, and the insert rods 56 pass through the separation frame 51;

[0035] The outer side of the insertion rod 56 is fitted with a ball-head plug 57, and the telescopic end of the ball-head plug 57 stops on the lower side of the separation frame 51.

[0036] In this embodiment, the baffle plate 55 is fixed to the separation frame 51 by inserting the rod 56 and limiting it with the ball head plug 57. When disassembly is required, the baffle plate 55 can be removed by pressing the ball head plug 57, and then the filter screen 54 can be replaced. Preferably, in order to improve the sealing performance of the baffle plate 55, sealing rings can be provided around the baffle plate 55 to ensure its water-blocking sealing performance.

[0037] In some embodiments, the elastic mechanism 6 of the present invention includes a sleeve 61 pinned to the frame 1 and a guide rod 62 pinned to the separation frame 51, wherein the guide rod 62 and the sleeve 61 are inserted into each other.

[0038] A nut 63 is threaded onto the outer side of the guide rod 62, and a spring 64 is provided between the nut 63 and the end face of the sleeve 61.

[0039] Based on the above embodiments, in this embodiment, the outer side of the sleeve 61 is provided with a guide groove 65, and the outer side of the guide rod 62 is threaded with a guide bolt 66, which slides in the guide groove 65.

[0040] Specifically, in this embodiment, the design of the sleeve 61 and guide rod 62, in conjunction with the spring 64, satisfies the shaking function of the separation frame 51. The nut 63 is used to compress and adjust the effective length of the spring 64 to avoid the problem of elastic fatigue after the spring 64 has been stretched for a long time. Of course, the guide bolt 66 can also be removed to separate the guide rod 62 and the sleeve 61, and then the spring 64 can be replaced directly.

[0041] It should be noted that a vibration motor 7 is also fixedly installed at the bottom of the separation frame 51. The vibration motor 7 is used to keep the entire separation frame 51 in a vibrating state during separation, so as to ensure the convenience of sand discharge. Of course, the bottom of the fully loaded separation frame 51 is connected to a drain pipe 8, which is used to discharge the water that falls into the bottom of the filter screen 54. This forms a thorough separation of stone, sand and water in the waste material.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
