Detailed implementation manners

[0021] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As Figures 1-4 shown, a uniform feeding device for an active calcium powder grinder includes a vertical cylinder 1 and a first grinding table 24 and a second grinding table 36 that are respectively rotatably arranged therein and rotate in opposite directions between them. A vent pipe 23 that rotates on the top of the vertical cylinder 1 is fixedly installed on the first grinding table 24, and the vent pipe 23 moves vertically so that the distance between the first grinding table 24 and the second grinding table 36 can be adjusted.

[0023] Specifically, a feed port 12 communicating with the inside of the vertical cylinder 1 is fixedly installed at the top of the vertical cylinder 1, and a discharge port 11 is opened at the bottom of the vertical cylinder 1. By putting large pieces of active calcium into the vertical cylinder 1 along the feed port 12, the active calcium is then ground into powder after passing between the first grinding table 24 and the second grinding table 36.

[0024] Furthermore, the first grinding table 24 and the second grinding table 36 can be rotated respectively by using a motor in cooperation with a gear drive; or by using a single motor in cooperation with a planetary gear set to rotate the first grinding table 24 and the second grinding table 36 and keep them rotating in opposite directions; or any other known driving method for the first grinding table 24 and the second grinding table 36 to rotate respectively by those skilled in the art can be used.

[0025] Furthermore, the way the ventilation pipe 23 moves in the vertical direction can be by the pushing of an electric push rod; it can also be through a motor cooperating with gears and racks; or any other way known to those skilled in the art to drive the ventilation pipe 23 to move in the vertical direction is acceptable.

[0026] In the above technical solution, by making the first grinding table 24 and the second grinding table 36 rotate in the vertical cylinder 1 respectively and with opposite rotation directions between them, the grinding effect on the active calcium powder is improved. Further, by using the ventilation pipe 23 to move vertically, the distance between the first grinding table 24 and the second grinding table 36 can be adjusted, so that the distance between the first grinding table 24 and the second grinding table 36 can be adjusted according to different grinding degrees, thereby improving the adaptability.

[0027] As a further technical solution provided by the present utility model, it further includes a support table 21 slidably arranged on the top of the vertical cylinder 1, and the top end of the ventilation pipe 23 is rotatably arranged at the bottom of the support table 21, and the output end of the main electric push rod 22 fixedly installed on the top of the vertical cylinder 1 is fixedly installed at the bottom of the support table 21.

[0028] Specifically, as Figure 3 shown, by using the ventilation pipe 23 to rotate at the bottom of the support table 21, when the ventilation pipe 23 rotates, by using the main electric push rod 22 to push the support table 21, the ventilation pipe 23 can be driven to move in the vertical direction, so as to adjust the distance between the first grinding table 24 and the second grinding table 36.

[0029] Further, a main gear 32 and a cylindrical gear 34 are rotatably arranged on the inner wall of the vertical cylinder 1 along the axis of the ventilation pipe 23, and a sun gear 33 rotatably arranged on the inner wall of the vertical cylinder 1 meshes with the main gear 32 and the cylindrical gear 34 respectively. A fixed block 3 is fixedly installed on the main gear 32, and the limiting rods 27 symmetrically and fixedly installed on the outer wall of the ventilation pipe 23 slide vertically in the vertical grooves 31 symmetrically opened in the fixed block 3.

[0030] Specifically, as Figure 3 shown, a main motor 35 is fixedly installed on the top of the vertical cylinder 1, and the output end of the main motor 35 is fixedly installed on the sun gear 33 along the axis of the sun gear 33. By making the limiting rods 27 slide vertically in the vertical grooves 31 symmetrically opened in the fixed block 3, when the main motor 35 is used to drive the sun gear 33 to rotate, at this time the sun gear 33 meshes with the main gear 32 and the cylindrical gear 34 respectively, so that the second grinding table 36 fixedly installed on the cylindrical gear 34 rotates, and at the same time the main gear 32 rotates to drive the fixed block 3 to rotate. Under the limitation of the vertical grooves 31 on the limiting rods 27, the ventilation pipe 23 rotates synchronously with the fixed block 3. At this time, the first grinding table 24 at the bottom end of the ventilation pipe 23 rotates with the fixed block 3 and rotates in the opposite direction to the second grinding table 36.

[0031] Furthermore, a plurality of grinding grooves 25 arranged in a circular array are formed on the grinding surface of the first grinding table 24.

[0032] Specifically, by using the plurality of grinding grooves 25, larger particles of active calcium can stay in the grinding grooves 25, and when the first grinding table 24 and the second grinding table 36 rotate relative to each other, the active calcium in the grinding grooves 25 is ground and broken. It can also cooperate with the main electric push rod 22 to drive the second grinding table 36 to reciprocate vertically when the first grinding table 24 and the second grinding table 36 rotate relative to each other, so that larger particles of active calcium are squeezed and ground, thereby improving the grinding effect.

[0033] Furthermore, a blower 2 communicating with the top end of the air pipe 23 is fixedly installed on the support table 21, and a plurality of air vent holes 26 corresponding to the grinding grooves 25 are formed on the first grinding table 24. The air vent holes 26 are horizontally arranged, the first end of the air vent hole 26 communicates with the air pipe 23, and the second end of the air vent hole 26 faces the grinding surface of the second grinding table 36.

[0034] Specifically, as Figure 4 shown, by using the blower 2 at the top end of the air pipe 23 to blow air into the air pipe 23, when the first grinding table 24 and the second grinding table 36 rotate relative to each other for grinding, the air blown in the air pipe 23 is blown along the plurality of air vent holes 26, thereby accelerating the fluidity of the particles in the grinding grooves 25 to accelerate the feeding.

[0035] Further, the air pipe 23 is a stainless steel pipe.

[0036] Furthermore, scraping rods 37 that are symmetrically and fixedly installed on the second grinding table 36 and are movable on the inner wall of the vertical cylinder 1 are provided.

[0037] Specifically, as Figure 2 shown, the rotation and grinding of the second grinding table 36 can also drive the scraping rods 37 to rotate and scrape the powder adhering to the inner wall of the vertical cylinder 1, thereby reducing the problem of powder accumulation and residue.

[0038] Working principle: When the sun gear 33 is driven to rotate by the main motor 35, the sun gear 33 meshes with the main gear 32 and the cylindrical gear 34 respectively, so that the second grinding table 36 fixedly installed on the cylindrical gear 34 rotates. At the same time, the main gear 32 rotates to drive the fixed block 3 to rotate. Under the limitation of the vertical groove 31 on the limiting rod 27, the air pipe 23 rotates synchronously with the fixed block 3. At this time, the first grinding table 24 at the bottom end of the air pipe 23 rotates with the fixed block 3 and rotates in the opposite direction to the second grinding table 36. By using the main electric push rod 22 to push the support table 21, the air pipe 23 can be driven to move vertically, so as to adjust the distance between the first grinding table 24 and the second grinding table 36. At the same time, the main electric push rod 22 is used to drive the second grinding table 36 to move vertically back and forth when the first grinding table 24 and the second grinding table 36 rotate relatively, so that the larger particles of active calcium are squeezed and ground, thereby improving the grinding effect. By using the blower 2 at the top end of the air pipe 23 to blow air into the air pipe 23, when the first grinding table 24 and the second grinding table 36 rotate relatively for grinding, the air blown in the air pipe 23 is blown along a plurality of ventilation holes 26, so as to accelerate the fluidity of the particles in the grinding groove 25 and accelerate the feeding.

[0039] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
