[0002] Scrubbing sand is a kind of raw sand for casting. It is obtained by scrubbing, washing, grading, drying and other processes of natural silica sand, and the mud content is less than 0.5%.

[0003] The scrubbing sand ore slurry is first input into the inner tank through the conveying pipe for sedimentation and then overflows into the outer tank. Due to the different qualities of the sand particles, the coarse sand particles (large mass) will gradually sink and be discharged through the primary drainage pipe at the lower end of the inner tank, while the fine sand particles (small mass) will enter the outer tank with the overflowing slurry and be discharged through the secondary drainage pipe on one side, thus completing the grading work; however, the conveying pipe is fixedly installed, and the nozzle on the conveying pipe is also fixed in direction, that is, it is always set upwards, so the sand particles entering the inner tank are not evenly distributed, affecting the sedimentation and separation effect.

[0004] Therefore, in order to solve the above problems, a hydraulic classifier is proposed for scrubbing sand production. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a hydraulic classifier for scrubbing sand production, comprising an outer tank 1 and an inner tank 2, the outer side of the inner tank 2 is fixedly mounted with the outer tank 1, the lower side of the outer tank 1 is fixedly mounted with a support frame 10, the support frame 10 plays a supporting role; the lower end of the inner tank 2 extends out of the outer tank 1 to expand the volume of the inner tank 2 and provide sufficient space for the arrangement of other components; a delivery pipe 4 is rotatably mounted inside the inner tank 2, a nozzle 5 is evenly connected and mounted on the upper side of the delivery pipe 4 along the axial direction, one end of the delivery pipe 4 is rotatably assembled with the inner tank 2 through a rotating seat 3, the other end of the delivery pipe 4 extends out of the inner tank 2, the delivery pipe 4 and the nozzle 5 are used to transport scrubbing sand mortar into the inner tank 2.

[0021] The support frame 10 is fixedly installed with a base 8 and a distribution pipe 6. The distribution pipe 6 is connected and assembled with the delivery pipe 4 through a rotating joint. The distribution pipe 6 is composed of a main pipe and multiple auxiliary pipes, and the rotating joint is an existing component. When in use, the distribution pipe 6 is connected with the scrubbing machine through a pump, and the scrubbing mortar is pressurized and sent into the delivery pipe 4; the base 8 is installed with a driving assembly 9, and a transmission assembly 7 is installed between the driving assembly 9 and the delivery pipe 4. The driving assembly 9 is used to reciprocate the transmission assembly 7, thereby reciprocatingly swinging each delivery pipe 4, changing the output direction of the scrubbing mortar, and improving the uniformity of the distribution of the scrubbing sand particles in the inner tank 2.

[0022] Specifically, the number of the delivery pipes 4 is at least 3 arranged in parallel, and the distance between the delivery pipes 4 is 20 cm to 30 cm, so as to ensure the delivery space of the scrubbing mortar material and provide sufficient space for mutual mixing.

[0023] Specifically, the transmission assembly 7 includes a rectangular frame 72 and a gear 74. The gears 74 are fixedly installed on the circumferential sides of the conveying pipe 4. The racks 71 are evenly fixedly installed on the inner side of the rectangular frame 72. The racks 71 are staggered up and down, and the racks 71 are respectively engaged and assembled with the gears 74; when the rectangular frame 72 is driven to reciprocate by the driving assembly 9, because the adjacent racks 71 are staggered up and down, the adjacent gears 74 will rotate synchronously in opposite directions, thereby causing the adjacent conveying pipes 4 to rotate synchronously in opposite directions.

[0024] Furthermore, a guide wheel 73 is rotatably installed on the side wall of the inner tank 2, and the guide wheel 73 is rollingly installed on the upper and lower sides of the rectangular frame 72; the guide wheel 73 is used to rollingly support the rectangular frame 72, which improves the translation stability while also preventing the rectangular frame 72 from deforming and affecting the meshing transmission.

[0025] Specifically, the driving assembly 9 includes a reduction motor 94 and a guide frame 91. The guide frame 91 is fixedly installed on the lower surface of the rectangular frame 72. The guide frame 91 is vertically arranged and has a rectangular long hole formed inside. One end of the first transmission rod 92 is rotatably installed at the end of the base 8 away from the support frame 10. The other end of the first transmission rod 92 is slidably installed in the guide frame 91 through a roller, so that the first transmission rod 92 can swing with the lower end as the center and move the guide frame 91 at the upper end.

[0026] A reduction motor 94 is fixedly installed on the upper side of the base 8, and a wheel 95 is fixedly installed on the output end of the reduction motor 94. One end of the second transmission rod 93 is rotatably installed at the eccentric edge of the wheel 95, and the other end of the second transmission rod 93 is rotatably assembled with the side wall of the first transmission rod 92; when the reduction motor 94 is working, the wheel 95 is continuously rotated, and the first transmission rod 92 is swung through the eccentrically installed second transmission rod 93, and the roller at the upper end of the first transmission rod 92 will move up and down in the guide frame 91 to offset the ups and downs of the upper end of the first transmission rod 92 during swinging, thereby horizontally reciprocating the rectangular frame 72.

[0027] Furthermore, the rotational connection between the second transmission rod 93 and the first transmission rod 92 is located at one-third of the lower side of the first transmission rod 92. The rotational connection position here can amplify the swing amplitude of the second transmission rod 93, so that the swing amplitude of the upper end of the first transmission rod 92 is larger; the second transmission rod 93, the reduction motor 94 and the wheel 95 can reduce the volume as much as possible while meeting the driving strength, and the miniaturized design can reduce the production cost.

[0028] like Figure 4 As shown, the maximum angle between the nozzle 5 and the vertical plane is 60°, which prevents the nozzles 5 from colliding with each other and causing excessive turbulence, so that the scrubbing mortar material always maintains appropriate fluidity for sedimentation and separation.

[0029] The working principle of this embodiment:

[0030] The reduction motor 94 is electrically connected to the controller in the external control cabinet; when working, the reduction motor 94 continuously rotates the wheel 95, and the first transmission rod 92 is swung through the eccentrically installed second transmission rod 93, and the roller at the upper end of the first transmission rod 92 will move up and down in the guide frame 91, thereby horizontally reciprocating the rectangular frame 72, so that the adjacent gears 74 will rotate synchronously in opposite directions, so that the adjacent conveying pipes 4 will also rotate synchronously in opposite directions, and the nozzle 5 will swing output appropriately to improve the uniformity of sand distribution in the inner tank 2; the coarse sand particles will gradually sink and be discharged through the primary drainage pipe at the lower end of the inner tank 2, while the fine sand particles will enter the outer tank 1 with the overflowed slurry and be discharged through the secondary drainage pipe on one side.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
