[0025] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0026] like Figure 1-Figure 6 As shown, the sand mill material outlet anti-splashing device provided in this embodiment includes a connecting head 1, one end of the connecting head 1 is fixedly connected to an arc tube 2, one end of the arc tube 2 is connected to an elbow 3, the bottom end of the elbow 3 is fixedly connected to an energy reducing water wheel 4, a buffer tube 5 is installed on the outer side of the bottom of the energy reducing water wheel 4, the bottom end of the buffer tube 5 is fixedly connected to an elbow 6, and the bottom end of the elbow 6 is installed with a water outlet 7.

[0027] Through the setting of the energy-reducing water wheel 4, the material released from the material outlet of the sand mill will first be decelerated by the arc pipe 2 and the elbow 3, and then enter the energy-reducing water wheel 4 to collide with the spiral blade 12, and the kinetic energy is converted into mechanical potential energy, thereby consuming the impact force of the material. After that, the material enters the buffer pipe 5 and then passes through the elbow 6 and flows out from the water outlet 7, completely consuming the kinetic energy of the material, thereby preventing splashing. When in use, the water outlet 7 is close to the inner wall of the material receiving container. Through the setting of the elbow 6, the water outlet 7 and the inner wall of the material receiving container maintain a certain angle, thereby further preventing splashing.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the other end of the connector 1 is fixedly connected with a connecting flange 8, and a filter screen 9 is fixedly installed on the inner side of the connector 1. The filter screen 9 is provided to prevent the grinding medium in the sand mill from flowing out, and also plays a role in slowing down the material. The connecting flange 8 is convenient for connecting with the sand mill.

[0029] In this embodiment, if Figure 1 , Figure 3 and Figure 5As shown, the energy reducing water wheel 4 includes a sleeve 10 threadedly connected to the bottom of the elbow 3 and a rotating shaft 11 rotatably mounted inside the sleeve 10, a spiral blade 12 is fixedly connected to the outside of the rotating shaft 11, and a bracket 13 rotatably matched with the rotating shaft 11 is fixedly connected to the inside of the sleeve 10. Through the setting of the spiral blade 12, the material impacts on the spiral blade 12, which will drive the spiral blade 12 to rotate, thereby consuming kinetic energy.

[0030] In this embodiment, if Figure 1 , Figure 3 and Figure 4 As shown, the arc tube 2 is a brass arc tube. By setting the arc tube 2 as a brass arc tube, the heat of the material can be dissipated, and the brass arc tube is convenient to bend. The diameter of the buffer tube 5 is twice the diameter of the arc tube 2. The diameter of the buffer tube 5 is twice the diameter of the arc tube 2, which can slow down the flow of the material. A transparent window 14 is provided on the outer wall of the buffer tube 5. The transparent window 14 is convenient for observing the depth of the material in the buffer tube 5.

[0031] In this embodiment, if Figure 1 , Figure 3 and Figure 6 As shown, the water outlet end of the water outlet head 7 is set as a flat tube, and a grid groove 15 is set on the inner side of the water outlet head 7. By setting the water outlet end of the water outlet head 7 as a flat tube, the contact area between the material and the receiving container can be increased, thereby preventing splashing, and the setting of the grid groove 15 can also prevent splashing.

[0032] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the connector 1, the arc pipe 2, the elbow 3, the energy reducing water wheel 4, the buffer pipe 5, the elbow 6, and the water outlet 7 are all threadedly connected. The threaded connection is convenient for installation and disassembly of each component.

[0033] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a sand mill material outlet anti-splashing device provided in this embodiment is as follows:

[0034] Step 1: Connect the device to the material outlet of the sand mill, and then place the water outlet head 7 against the inner wall of the material receiving container;

[0035] Step 2: Then discharge the material. After being filtered by the filter screen 9, the material is decelerated by the arc pipe 2 and the elbow 3, and then enters the energy reduction water wheel 4, impacting the spiral blade 12, which will drive the spiral blade 12 to rotate, thereby consuming kinetic energy;

[0036] Step 3: Finally, the material falls into the buffer pipe 5, and then flows into the receiving container from the water outlet 7 through the elbow 6.

[0037] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
