Description

Technical Field

[0001] The utility model belongs to the technical field of concrete slurry screening, in particular to a slurry screening device for concrete processing. Background Art

[0002] Concrete mortar usually needs to be screened during the manufacturing process to screen out material particles that do not meet the requirements. Traditional concrete screening devices use an electric motor to drive the screen cylinder to rotate, and then the materials that meet the size leak out from the screen holes, fall into the screen tank, and are discharged from the device through a discharge pipe. The materials that meet the size leak out from the screen cylinder into the screen tank and are discharged from the device through a discharge pipe, while the materials that do not meet the size remain in the screen cylinder. Then the switch valve is opened to discharge the materials that do not meet the size from the discharge pipe. However, when screening the slurry, concrete slurry is likely to remain in the screen cylinder, causing waste and easily affecting subsequent screening work.

[0003] The Chinese patent with the authorization announcement number CN219923578U discloses a concrete slurry screening device, including a device body, the interior of the device body is hollow, a feed port is provided at the top of the device body, a discharge port is provided at the bottom of the device body, a first filter screen and a second filter screen are sequentially arranged at the top of the inner top of the device body from top to bottom, the aperture of the first filter screen is larger than the aperture of the second filter screen, a first discharge assembly is correspondingly arranged on the first filter screen, and a second discharge assembly is correspondingly arranged on the second filter screen, a partition is provided at the bottom of the device body with a middle portion penetrating therethrough, a cleaning brush is longitudinally slidably connected below the partition, the end of the cleaning brush abuts against the side wall of the device body, and a check valve is provided at the discharge port. Avoid material adhering to the inner wall to prevent affecting subsequent slurry screening.

[0004] However, the above patent has the following disadvantages:

[0005] The slurry screening efficiency of the above-mentioned patent is low, and when screening foreign particles, since the concrete slurry is relatively sticky, concrete slurry still remains on many foreign particles, and these concrete slurries are discharged together with the foreign particles. After a long period of slurry screening work, a large amount of waste will be accumulated. Utility Model Content

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0022] refer to Figure 1-5 A slurry screening device for concrete processing includes a shell 48, a chassis 58 is fixedly connected to the bottom of the shell 48, a centrifugal cylinder 62 is rotatably connected to the upper side of the chassis 58, a bearing 61 is arranged between the centrifugal cylinder 62 and the chassis 58, a debris discharge port 59 is opened at the bottom of the chassis 58, two cylinders 57 are fixedly connected to the bottom of the chassis 58 at both sides of the debris discharge port 59, the extended ends of the two cylinders 57 pass through the chassis 58 and are fixedly connected to a movable plug 60, and the bottom side of the movable plug 60 is tightly fitted with the conical surface of the chassis 58.

[0023] A rotating centrifugal drum 62 is provided to utilize centrifugal force to improve pulp screening efficiency.

[0024] refer to Figure 3-5 A column 63 is fixedly connected to the center of the top of the movable plug 60, and a plurality of levers 64 are evenly distributed and fixedly connected to the column 63.

[0025] The lever 64 is used to continuously move the foreign particles during the slurry screening process to prevent the accumulation of foreign particles from affecting the concrete slurry passing through the sieve holes of the centrifugal drum 62, thereby ensuring the slurry screening effect.

[0026] refer to Figure 1-2 A top plate 49 is fixedly connected to the top of the outer shell 48, a support 50 is fixedly connected to the top of the top plate 49, a centrifugal cylinder 62 is rotatably connected to the top plate 49 and the support 50, a hopper 52 which is sleeved on the outside of the centrifugal cylinder 62 is fixedly connected to the support 50, and a discharge port 56 is provided at the bottom of the outer shell 48 on one side of the chassis 58.

[0027] refer to Figure 1 A driven wheel 53 is fixedly connected to the outer side of one end of the centrifugal cylinder 62 extending out of the top plate 49, and a motor 51 is fixedly connected to the support 50 at one side of the hopper 52. The output end of the motor 51 passes through the support 50 and is transmission-connected to a driving wheel 54. The driving wheel 54 and the driven wheel 53 are transmission-connected via a transmission belt 55.

[0028] In this embodiment, initially, the operator connects the power supply and control system of the present invention. At this time, the cylinder 57 is in a retracted state, and the movable plug 60 is in close contact with the conical surface of the chassis 58. When slurry screening is required, the concrete slurry is put into the centrifugal drum 62 from the hopper 52, and then the motor 51 is started. Under the transmission of the driving wheel 54 and the driven wheel 53, the centrifugal drum 62 is rotated at a high speed, thereby generating centrifugal force.

[0029] Under the action of centrifugal force, the concrete slurry in the centrifugal barrel 62 quickly passes through the sieve holes on the centrifugal barrel 62, thereby improving the screening efficiency, and the cement slurry adhering to the surface of the impurity particles can also be separated and collected, reducing waste. The fine mortar passing through the centrifugal barrel 62 falls into the outer shell 48 and is finally discharged from the discharge port 56.

[0030] During the high-speed rotation of the centrifugal barrel 62, under the action of centrifugal force and gravity, the impurities remaining in the centrifugal barrel 62 accumulate downward and accumulate on the inner wall of the centrifugal barrel 62. The columns 63 are used to stir and disperse the accumulated impurity particles during the rotation of the centrifugal barrel 62 to prevent the impurity particles from piling up too tightly and affecting the passage of the mortar, thereby ensuring the slurry screening effect.

[0031] When the slurry screening is completed and all the mortar in the outer shell 48 is discharged, the cylinder 57 is started to extend the cylinder 57, thereby raising the movable plug 60, and then the interior of the centrifugal cylinder 62 is connected with the impurity discharge port 59, and the impurity particles remaining in the centrifugal cylinder 62 are discharged from the impurity discharge port 59. After all the mortar is discharged, the device is reset and waits for the next slurry screening work.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
