[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The cement mortar and gravel separation device of this utility model is described below with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, the cement mortar and aggregate separation device of this utility model embodiment may include a housing 10, a centrifugal mechanism 20, a swing mechanism 40, and a discharge mechanism 60. The centrifugal mechanism 20 is disposed inside the housing 10 and passes through the side wall of the housing 10. A water storage tank 31 is disposed above the centrifugal mechanism 20. A plurality of nozzles 32 are connected to the bottom surface of the water storage tank 31. A water supply pipe 33 is connected to the water storage tank 31 and passes through the top wall of the housing 10. The swing mechanism 40 is disposed on the housing 10 and is connected to the water storage tank 31.

[0022] It should be noted that the water supply pipe 33 is connected to an external water pump. The water pump delivers water to the water supply pipe 33, which is then temporarily stored in the water storage tank 31 before being sprayed through the nozzle 32.

[0023] A support 51 is provided at the bottom of the housing 10. Two mounting plates 52 are arranged opposite each other on the support 51. Both mounting plates 52 are rotatably connected to a rotating shaft 53. The two rotating shafts 53 are respectively connected to the two sides of the housing 10. A hydraulic column 54 is hinged between the support 51 and the housing 10. The discharge mechanism 60 is located at the bottom of the housing 10.

[0024] Specifically, the operator first controls the piston end of the hydraulic column 54 to extend, and with the cooperation of the rotating shaft 53, lifts one side of the housing 10 upward, making the centrifugal mechanism 20 tilted. Then, the operator opens the centrifugal mechanism 20 and delivers mortar into it. After delivery, the operator closes the centrifugal mechanism 20 and controls the piston end of the hydraulic column 54 to retract, and with the cooperation of the rotating shaft 53, makes the housing 10 horizontal.

[0025] Then, the centrifuge mechanism 20 is started to rotate, causing the mortar slurry to be thrown out through the screen holes of the centrifuge mechanism 20, while the sand and gravel remain in the centrifuge mechanism 20. During this process, the water pump is started to deliver water to the water supply pipe 33, and then it is temporarily stored in the water storage tank 31. Then, the outer wall of the centrifuge mechanism 20 is rinsed through the nozzle 32 to prevent the screen holes of the outer wall of the centrifuge mechanism 20 from being blocked by cement slurry, fine sand, etc. At the same time, the swing mechanism 40 is started to drive the water storage tank 31 to swing slightly. The water flow impacts the outer wall of the centrifuge mechanism 20 in different directions and with different forces, which can more effectively loosen and remove impurities on the outer wall of the centrifuge mechanism 20.

[0026] During the separation process, the slurry can be discharged in time through the discharge mechanism 60. After the separation is completed, the piston end of the control hydraulic column 54 retracts again. With the cooperation of the rotating shaft 53, one side of the shell 10 is turned downward. Then, the staff opens the centrifuge mechanism 20, so that the centrifuge mechanism 20 discharges the sand and gravel inside in an inclined state.

[0027] The cement mortar and gravel separation device of this utility model can effectively wash the outer wall of the centrifuge mechanism, remove cement slurry and fine sand adhering to the outer wall of the centrifuge mechanism, prevent the screen holes from being blocked, and thus effectively improve the sand and gravel separation efficiency.

[0028] In one embodiment of this utility model, such as Figure 1 As shown, the centrifuge mechanism 20 includes a sieve cylinder 21, a first driver 22, a cover 23, and a rotating rod 24. The sieve cylinder 21 is disposed inside the housing 10. The first driver 22 is disposed on one side of the housing 10. The output end of the first driver 22 passes through the housing 10 and is connected to the sieve cylinder 21. The cover 23 is threaded to one end of the sieve cylinder 21 and passes through the side wall of the housing 10. The rotating rod 24 is connected to the cover 23.

[0029] It should be noted that the first driver 22 described in this embodiment can be a motor. The size of the screen holes on the outer wall of the screen cylinder 21 is smaller than the size of the sand and gravel. The first driver 22 can drive the screen cylinder 21 to rotate. During the rotation of the screen cylinder 21, the slurry will be thrown out from the screen holes of the screen cylinder 21, while the sand and gravel will remain in the screen cylinder 21. When it is necessary to add or discharge material to the screen cylinder 21, the operator rotates the rotating rod 24, which will drive the cover 23 to rotate, thereby causing it to detach from the screen cylinder 21, thus facilitating the addition and discharge of material to the screen cylinder 21.

[0030] In one embodiment of this utility model, such as Figure 3 As shown, the swing mechanism 40 includes a bracket 41, a second driver 42, a rotating plate 43, a sliding rod 44, a sliding sleeve 45, a swing frame 46, and a swing shaft 47. The bracket 41 is disposed on one side of the housing 10, the second driver 42 is disposed on the bracket 41, the rotating plate 43 is connected to the output end of the second driver 42, the sliding rod 44 is slidably connected to the rotating plate 43, the sliding sleeve 45 is connected to the sliding rod 44, the sliding sleeve 45 is slidably connected to the swing frame 46, the swing frame 46 is fixedly sleeved on the swing shaft 47, one end of the swing shaft 47 is rotatably connected to the bracket 41, and the other end passes through the housing 10 and is connected to the water storage cylinder 31.

[0031] It should be noted that the second driver 42 described in this embodiment can be a motor. The second driver 42 can drive the rotating plate 43 to rotate. During the rotation of the rotating plate 43, the slide rod 44 will slide up and down in the screen hole of the rotating plate 43. At the same time, the slide rod 44 will drive the sliding sleeve 45 to slide back and forth on the swing frame 46. With the cooperation of the swing shaft 47, the swing frame 46 will swing. At the same time, the swing shaft 47 will drive the water storage cylinder 31 to swing back and forth in a small amplitude, so that the water flow impacts the outer wall of the centrifuge mechanism 20 in different directions and intensities, which can more effectively loosen and remove impurities on the outer wall of the centrifuge mechanism 20 and improve the rinsing effect.

[0032] In one embodiment of this utility model, such as Figure 1 As shown, the discharge mechanism 60 includes two guide blocks 61, a discharge pipe 62, and a valve 63. The two guide blocks 61 are respectively disposed on the bottom wall of the housing 10, the discharge pipe 62 is connected to the bottom wall of the housing 10 and is located between the two guide blocks 61, and the valve 63 is disposed on the discharge pipe 62.

[0033] Understandably, by setting two guide blocks 61, the slurry thrown out of the screen cylinder 21 is guided to flow into the discharge pipe 62. By controlling the valve 63 to open, the slurry can be discharged from the discharge pipe 62.

[0034] In one embodiment of this utility model, such as Figure 2 As shown, the housing 10 is provided with an observation window 11.

[0035] It is understandable that the observation window 11 is provided to facilitate staff to observe the separation of sand and gravel inside the shell 10.

[0036] In summary, the cement mortar and sand separation device of this utility model can effectively wash the outer wall of the centrifuge mechanism, remove cement slurry and fine sand adhering to the outer wall of the centrifuge mechanism, prevent the screen holes from clogging, and thus effectively improve the sand and gravel separation efficiency.
