Separating wheel for sand mill

Abstract

The separation wheel comprises a separation wheel body, a containing cavity is formed in the separation wheel body, a material passing groove is formed in the surface of the outer side of the separation wheel body, and an included angle larger than 0 degree and smaller than 90 degrees is formed between the connecting line of the outer end opening of the material passing groove and the central axis of the separation wheel body and the connecting line of the inner end opening of the material passing groove and the central axis of the separation wheel body. The material passing groove communicates with the containing cavity. According to the separation wheel for the sand mill, centrifugal force can be generated through the rotating wheel, due to the fact that the mass of grinding beads is larger than that of slurry, the heavy grinding beads are pushed away from the separation wheel under the large centrifugal force and cannot enter the material passing groove, the slurry can enter the material passing groove when the mass of the slurry is light, and therefore the slurry and the grinding beads are effectively separated, and the grinding efficiency is improved. The ground materials flow into the containing cavity along the material passing groove, and the ground materials can be discharged out of the grinding machine through the containing cavity.

Description

Technical Field

[0001] The utility model relates to the technical field of sand mills, in particular to a separating wheel for sand mills. Background Art

[0002] Sand mill is mainly used for wet grinding of chemical liquid products. It includes a grinding container, a main shaft, a grinding part and a separation part. There is a grinding chamber in the grinding container. The grinding part is located in the grinding chamber. The main shaft drives the grinding part to grind the material entering the grinding chamber through the grinding part and grinding beads. The separation part is used to separate the ground material from the grinding beads.

[0003] Currently, existing sand mills use gap-type separation devices, which are equipped with a fixed-size gap. The slurry flows out through the gap, while the grinding beads, because they are larger than the gap, are intercepted inside the sand mill. However, gap-type separation devices are only suitable for production scenarios where the slurry particles are relatively uniform in size and have low viscosity. Because the gap size is fixed, if the slurry particle size changes significantly or the viscosity increases, the separation is likely to be incomplete or the gap is blocked, and effective separation of the grinding beads and slurry cannot be achieved. Utility Model Content

[0004] Based on this, it is necessary to provide a separation wheel for a sand mill.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A separation wheel for a sand grinder, wherein a accommodating cavity is provided inside the separation wheel, and a feeding trough is provided on the side wall of the separation wheel. The inner and outer ports of the feeding trough respectively form a central angle of the feeding trough with the line connecting the rotation center of the separation wheel, the central angle of the feeding trough is greater than 0° and less than 90°, and the feeding trough is connected to the accommodating cavity.

[0007] In one embodiment, a first mounting hole is provided on the first end surface of the separation wheel, a second mounting hole is provided on the second end surface of the separation wheel, the width of the accommodating cavity is greater than the width of the first mounting hole, and the first mounting hole, the accommodating cavity and the second mounting hole are connected in sequence.

[0008] In one embodiment, there are multiple feed chutes.

[0009] In one embodiment, a plurality of the feed chutes are equidistantly spaced apart and arranged on the side wall of the separation wheel.

[0010] In one embodiment, a guide groove is provided on the outer surface of the separation wheel, and the guide groove extends from the outer port of the feed chute toward the inner side of the central angle of the feed chute.

[0011] In one embodiment, a plurality of guide grooves are formed on the outer surface of the separation wheel, and each of the guide grooves is located between two adjacent feed chutes.

[0012] The beneficial effect of the present invention is that the separation wheel for the sand mill can generate centrifugal force by rotating the wheel. Since the mass of the grinding beads is greater than the mass of the slurry, the heavier grinding beads are subjected to a larger centrifugal force and are pushed away from the separation wheel. The grinding beads cannot enter the trough, while the lighter slurry can enter the trough, thereby effectively separating the slurry from the grinding beads, and the ground material flows into the accommodating chamber along the trough, and the ground material can be discharged from the sand grinder through the accommodating chamber.

[0020] In one embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, a separating wheel 10 for a sand grinder is provided. An accommodating cavity 101 is provided inside the separating wheel 10. A feeding trough 102 is provided on the side wall of the separating wheel 10. The inner and outer ports of the feeding trough 102 respectively form a central angle of the feeding trough 102 with the line connecting the rotation center of the separating wheel 10. The central angle of the feeding trough 102 is greater than 0° and less than 90°, and the feeding trough 102 is connected with the accommodating cavity 101. A first mounting hole 103 is provided on the first end surface of the separating wheel 10, and a second mounting hole 106 is provided on the second end surface of the separating wheel 10. The width of the accommodating cavity 101 is greater than the width of the first mounting hole 103. The first mounting hole 103, the accommodating cavity 101 and the second mounting hole 106 are connected in sequence.

[0021] In this embodiment, the material and grinding beads are fed into the grinding chamber of the sand mill through a feed pump, the first mounting hole 103 and the second mounting hole 106 are used to install the main shaft, and part of the main shaft is located in the accommodating chamber 101, and a plurality of feed holes are provided on the outer surface of the main shaft located in the accommodating chamber 101, and a discharge trough is provided in the main shaft, which is connected to the plurality of feed holes; the main shaft and the separating wheel 10 are located in the grinding chamber, wherein the feed pump, the main shaft, and the separating wheel 10 are components in the sand mill, and the main shaft can rotate. After the material is ground to form slurry, the main shaft drives the separation wheel 10 to rotate to generate centrifugal force. The heavier grinding beads are subjected to greater centrifugal force and are pushed away from the separation wheel, so that the grinding beads cannot enter the feed trough 102. The pressure generated by the feed pump when feeding sends the slurry into the feed trough 102, thereby realizing the separation of the slurry and the grinding beads. Among them, the feed trough 102 tilted from the outside of the separation wheel 10 to the inside of the separation wheel 10 can effectively guide the slurry to flow along the feed trough 102, which helps to control the flow direction of the slurry so that the slurry can better enter the feed trough 102, thereby improving the effect of the separation wheel 10 in separating the slurry and the grinding beads. After that, the slurry flows into the accommodating chamber 101 along the feed trough 102, flows into the feed hole, and then discharges the slurry from the sander through the discharge trough.

[0022] In one embodiment, Figure 1 and Figure 2 As shown, there are multiple feed troughs 102. Specifically, the multiple feed troughs 102 can further guide the flow direction of the slurry, so that the slurry can enter each feed trough 102, and the amount of slurry separated by the separation wheel 10 is increased.

[0023] In one embodiment, Figure 1 and Figure 2 As shown, a plurality of feed troughs 102 are equidistantly spaced apart on the side wall of the separation wheel 10. Specifically, arranging the feed troughs 102 equidistantly spaced apart enables the separation wheel 10 to separate the slurry uniformly.

[0024] In one embodiment, Figure 2 and Figure 3 As shown, a guide groove 105 is provided on the outer surface of the separation wheel 10, and the guide groove 105 extends from the outer port of the feed trough 102 toward the inner side of the central angle of the feed trough 102. Specifically, the guide groove 105 can further guide the flow direction of the slurry, and the guide groove 105 has an inclined surface, which can improve the fluidity of the slurry on the guide groove 105, so that the slurry can better enter the feed trough 102.

[0025] In one embodiment, Figure 2 and Figure 3 As shown, a plurality of guide grooves 104 are formed on the outer surface of the separation wheel 10, and each guide groove 104 is located between two adjacent feed troughs 102. Specifically, the guide grooves 104 can further enhance the centrifugal force generated when the separation wheel 10 rotates, thereby allowing more slurry to gather near the separation wheel 10, thereby increasing the amount of slurry entering the feed trough 102.

[0026] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
