[0031] The following is combined with Figure 1-10 The specific implementation modes of the present utility model are further described in detail.

[0032] like Figure 1-10 As shown, a bottom-discharging vertical mill sand making machine comprises a lower cavity 1, a grinding disc 2 is rotatably provided at the upper end of the lower cavity 1, a box 3 is fixed at the upper end of the lower cavity 1, and the box 3 is a structure with an upper end opening, and the powder ground by the grinding disc 2 enters the lower cavity 1 through the box 3;

[0033] The lower cavity 1 is provided with a discharge channel, and the powder is discharged through the discharge channel.

[0034] In this device, the structure of feeding from the upper end is still retained. The unground material is added to the grinding disc 2 from the upper end, and the material is ground into powder by the grinding assembly. At this time, the powder relies on its own gravity to enter the discharge channel of the lower cavity 1, and then is discharged to the outside from the discharge channel.

[0035] The box body 3 plays a protective sealing role here, and cooperates with the upper protective cover of the device to form a seal, so that the powder produced during the grinding process will not leak, and can only enter the discharge channel and be discharged outward.

[0036] The box body 3 has a structure with a large upper end surface and a small lower end surface.

[0037] In the present device, the box body 3 is a polygonal structure, and the shape of the box body 3 is similar to a trumpet, which can ensure that the grinding disc 2 and the grinding assembly do not interfere with the grinding of the material and increase the convenience of subsequent entry into the discharge channel.

[0038] The discharge channel includes channel A4, channel B5 and channel C6. Powders can enter channel A4, channel B5 and channel C6 respectively. The heavy powder in channel A4 enters channel B5 and then enters channel C6. The powder in channel B5 enters channel C6.

[0039] In the present device, the entire lower cavity 1 is formed by splicing and welding plates, and the lower cavity 1 is a prismatic structure as a whole.

[0040] In this device, the ground powder enters different channels respectively. The powder enters different channels randomly and generally enters the corresponding channels according to the falling position. The powder that directly enters channel C6 will fall directly downward. The overall equipment is provided with a discharge port corresponding to channel C6, and this part of the powder is directly discharged from the discharge port.

[0041] The powder entering into the channel B5 falls downward into the channel C6 and is then discharged from the discharge port.

[0042] The powder material entering into the channel A4 falls downward into the channel B5, and then enters into the channel C6 from the channel B5, and is discharged from the discharge port.

[0043] The channel C6 is a vertical channel.

[0044] In this device, channel C6 is vertical, and the lower end is connected to the discharge port, and the discharge port is also in a vertical state, which is convenient for powder to fall. In order to increase the aesthetics and reduce the space volume, the outermost side of channel C6 is set to a triangular structure.

[0045] The lower end of the channel B5 is communicated with the channel C6, and the lower end of the channel B5 is an inclined structure and is inclined downward into the channel C6.

[0046] In this device, a notch A8 communicating with channel B5 is provided in the middle of channel C6, the lower end of notch A8 coincides with the lower end of channel B5, and channel B5 is inclined downward to notch A8, so that the powder in channel B5 can enter channel C6 conveniently.

[0047] The top of the channel B5 is a vertical structure.

[0048] The upper end of channel B5 is also a vertical structure, which facilitates the downward movement of powder.

[0049] The lower end of the channel A4 is communicated with the channel B5, and the lower end of the channel A4 is an inclined structure and is inclined downward into the channel B5.

[0050] In this device, a slot B9 communicating with channel A4 is provided in the middle of channel B5, the lower end of slot B9 coincides with the lower end of channel A, and channel A4 is tilted downward to slot B9, so that the powder in channel A4 can easily enter channel B5.

[0051] The upper end of the channel A4 is an inclined structure, and is inclined downward.

[0052] In the present device, the upper end of the channel A4 is arranged to be inclined, so that the powder entering the channel A4 can flow downward, and the lower end of the channel A4 is also inclined. The inclination direction of the upper end of the channel A4 is different from that of the lower end. Fig.10 As shown, the two are in a cross arrangement, and the lower end of channel A4 is inclined toward channel B5.

[0053] The channel B5 and the channel C6 are located on the same side, and the channel C6 is located on the outside.

[0054] The channel A4 is on a different side from the channel B5, and the channel A4 is located on the adjacent side of the channel B5.

[0055] In the present device, channel B5 and channel C6 are located on the same side, channel A4 is located on the side of channel B5, and there are two groups of channels B5, two groups of channels C6 and four groups of channels A4 in the entire device. The above multiple groups of channels together form a closed loop, and every two channels A4 form a group. The powder entering this channel A4 enters different channels B5 respectively, and finally flows into different channels C6, and then is discharged from the discharge port.

[0056] A tray 7 is fixed to the upper end of the lower cavity 1, the grinding disc 2 is rotatably connected to the tray 7, the box body 3 is fixed on the tray 7, and the lower end of the box body 3 is an open structure.

[0057] The tray 7 supports the grinding disc 2 in a bearing manner, and the box body 3 is installed on the tray 7. The lower end of the box body 3 is open, so that the powder material can easily enter the discharge channel.

[0058] In addition, we can also make the tray 7 and the box body 3 into a whole. In this device, the tray 7 and the box body 3 are separated to facilitate installation and subsequent maintenance.

[0059] The tray 7 is evenly distributed with a plurality of discharge ports on its circumference, and the powder enters the discharge channel through the discharge ports.

[0060] In the present device, the ground powder enters into channel A4, channel B5 and channel C6 respectively through the discharge port.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
