Description

Technical Field

[0001] The utility model relates to the technical field of ball mill grinding ball placement quantity control, in particular to a ball mill ceramic ball control mechanism. Background Art

[0002] The ball mill is a key equipment for crushing materials after they are broken. This type of grinding machine is a machine that has a certain number of steel balls as grinding media in its cylinder.

[0003] It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics and other production industries, for dry or wet grinding of various ores and other grindable materials. Ball mills are suitable for grinding various ores and other materials, and are widely used in beneficiation, building materials and chemical industries. They can be divided into dry and wet grinding methods. According to different discharge methods, they can be divided into grid type and overflow type.

[0004] When the ball mill is in use, in order to reduce the loss of ball milling media, ceramic grinding balls are used to replace steel balls. When the raw materials are ball milled, the ceramic grinding balls are attached to the cylinder lining due to inertia, centrifugal force and friction, and are carried away by the cylinder. When they are brought to a certain height, they are thrown down due to their own gravity. The falling ceramic grinding balls crush the materials in the cylinder like projectiles.

[0005] However, in actual operation, the number of grinding balls has a certain influence on the degree of grinding of the material. Therefore, the number of grinding balls needs to be controlled during use. However, the ball mill currently used does not have a mechanism to control the number of grinding balls when putting in the grinding balls. Therefore, a ball mill ceramic ball control mechanism is needed to solve the above problem. Utility Model Content

[0006] The utility model aims to provide a ceramic ball control mechanism for a ball mill, which has the advantage of limiting the number of grinding balls placed in the ball mill, thereby solving the problem that the ball mill currently used cannot effectively control the number of grinding balls when placing them.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ball mill ceramic ball control mechanism, comprising a mounting plate, a hole is opened on the upper surface of the mounting plate at the rear end thereof and connected to and installed with a feed pipe, a first mounting groove is opened on the upper surface of the mounting plate at the front end of the feed pipe, a spring hinge is embedded and installed in the first mounting groove, a second mounting groove is opened on the upper surface of the mounting plate at the front end of the first mounting groove, an electric telescopic rod is embedded and installed in the second mounting groove, and also includes a limit plate and a guide plate;

[0008] The guide plate is elastically mounted on the rear end of the lower surface of the mounting plate through a spring hinge;

[0009] Wherein, the material guide plate is located below the feed pipe;

[0010] The limit plate is fixedly installed at the bottom of the electric telescopic rod;

[0011] Wherein, the limiting plate is located below the material guide plate.

[0012] When using a ceramic ball control mechanism for a ball mill in the technical solution, the mounting plate is fixedly mounted at the medium inlet of the ball mill through the mounting hole, and the number of grinding balls to be placed is limited by programming the controller body. At this time, the grinding balls can be placed one by one through the feed pipe. After the grinding balls are placed in the feed pipe, they contact the guide plate and under the influence of gravity and the action of the spring hinge, the guide plate flips under the mounting plate, and the grinding balls are placed in the ball mill. When the guide plate flips, the touch rod moves downward, so that the flipping of the guide plate is sensed by the sensor body. Since the sensor body is electrically connected to the controller body, it is determined that one grinding ball is placed when the guide plate flips once. When the number of placed balls meets the production demand, the controller body starts the electric telescopic rod, so that the limit plate moves up, thereby limiting the guide plate and avoiding the placement of more grinding balls.

[0013] Preferably, mounting holes are respectively provided at the four corners of the upper surface of the mounting plate.

[0014] By respectively opening mounting holes at the four corners of the upper surface of the mounting plate, the mounting plate can be fixedly mounted at the medium inlet of the ball mill through the mounting holes.

[0015] Preferably, a sensor body is fixedly mounted on the upper surface of the mounting plate on the side of the feed pipe opposite to the first mounting groove, and a reserved hole is opened on the mounting plate below the sensor body.

[0016] A sensor body is fixedly mounted on the upper surface of the mounting plate on the side opposite to the feed pipe and the first mounting groove, and a reserved hole is opened on the mounting plate below the sensor body, so that the flipping of the guide plate can be sensed through the reserved hole.

[0017] Preferably, the sensor body adopts a distance sensor structure design, the sensor body is electrically connected to the controller body through a connecting line, and the controller body is electrically connected to the electric telescopic rod through a connecting line.

[0018] The sensor body is designed with a distance sensor structure, and the sensor body is electrically connected to the controller body through a connecting line. At the same time, the controller body is electrically connected to the electric telescopic rod through the connecting line. After programming the controller body, the number of grinding balls placed can be understood according to the number of flipping times of the guide plate sensed by the sensor body, and the electric telescopic rod is controlled by the controller body, so that the guide plate is limited by the limit plate installed at the bottom of the electric telescopic rod, thereby avoiding the placement of more grinding balls.

[0019] Preferably, a touch rod is fixedly mounted on the upper surface of the guide plate, the touch rod is located directly below the reserved hole, and the touch rod matches the sensor body.

[0020] A feeler rod is fixedly installed on the upper surface of the guide plate and is located directly below the reserved hole. Meanwhile, the feeler rod matches the sensor body, thereby preventing the grinding ball from entering the guide plate and affecting the sensor body.

[0021] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0022] The utility model provides a limit plate and a guide plate, and the guide plate is elastically mounted on the rear end of the lower surface of the mounting plate through a spring hinge. At the same time, the guide plate is located below the feed pipe, and the limit plate is fixedly mounted on the bottom of the electric telescopic rod. At the same time, the limit plate is located below the guide plate. In specific operation, the mounting plate is fixedly mounted at the medium placement inlet of the ball mill through the mounting hole, and the number of grinding balls placed is limited by programming the controller body. At this time, the grinding balls can be placed one by one through the feed pipe. After the grinding balls are placed in the feed pipe, they contact the guide plate and are held under gravity. Under the influence and action of the spring hinge, the guide plate flips under the mounting plate, and the grinding balls are placed in the ball mill. When the guide plate flips, the touch rod moves downward, so that the flipping of the guide plate is sensed by the sensor body. Since the sensor body is electrically connected to the controller body, it is determined that one grinding ball is placed when the guide plate flips once. When the number of placed balls meets the production demand, the controller body starts the electric telescopic rod, so that the limit plate moves up, thereby limiting the guide plate, thereby avoiding the placement of more grinding balls, thereby achieving the effect of limiting the number of grinding balls placed in the ball mill.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model is provided: a ball mill ceramic ball control mechanism, comprising a mounting plate 1, a hole is opened at the rear end of the upper surface of the mounting plate 1 and connected to and installed with a feed pipe 3, a first mounting groove 13 is opened on the upper surface of the mounting plate 1 at the front end of the feed pipe 3, a spring hinge 8 is embedded and installed in the first mounting groove 13, a second mounting groove 14 is opened on the upper surface of the mounting plate 1 at the front end of the first mounting groove 13, an electric telescopic rod 5 is embedded and installed in the second mounting groove 14, and also includes a limit plate 9 and a guide plate 10;

[0031] Specifically, the guide plate 10 is elastically mounted on the rear end of the lower surface of the mounting plate 1 through a spring hinge 8;

[0032] Wherein, the guide plate 10 is located below the feed pipe 3;

[0033] The limit plate 9 is fixedly installed at the bottom of the electric telescopic rod 5;

[0034] The limiting plate 9 is located below the material guiding plate 10 .

[0035] By setting a limit plate 9 and a guide plate 10, and elastically mounting the guide plate 10 on the rear end of the lower surface of the mounting plate 1 through a spring hinge 8, the guide plate 10 is located below the feed pipe 3, and the limit plate 9 is fixedly mounted on the bottom of the electric telescopic rod 5, and the limit plate 9 is located below the guide plate 10, and then in specific operation, the mounting plate 1 is fixedly mounted at the medium inlet of the ball mill through the mounting hole 2, and the number of grinding balls to be placed is limited by programming the controller body 6, at this time, the grinding balls can be placed one by one through the feed pipe 3, and after the grinding balls are placed in the feed pipe 3, they contact with the guide plate 10 and are under the influence of gravity. Under the action of the sound and spring hinge 8, the guide plate 10 is flipped under the mounting plate 1, and the grinding balls are placed in the ball mill. When the guide plate 10 is flipped, the touch rod 12 moves down, so that the flipping of the guide plate 10 is sensed by the sensor body 4. Since the sensor body 4 is electrically connected to the controller body 6, it is determined that one grinding ball is placed when the guide plate 10 is flipped once. When the number of placed balls meets the production demand, the controller body 6 starts the electric telescopic rod 5, so that the limit plate 9 moves up, thereby limiting the guide plate 10, thereby avoiding the placement of more grinding balls, and achieving the effect of limiting the number of grinding balls placed in the ball mill.

[0036] Furthermore, mounting holes 2 are respectively provided at the four corners of the upper surface of the mounting plate 1 .

[0037] By respectively opening mounting holes 2 at the four corners of the upper surface of the mounting plate 1 , the mounting plate 1 can be fixedly mounted at the medium inlet of the ball mill through the mounting holes 2 .

[0038] Furthermore, a sensor body 4 is fixedly mounted on the upper surface of the mounting plate 1 on the side of the feed pipe 3 opposite to the first mounting groove 13 , and a reserved hole 11 is opened on the mounting plate 1 below the sensor body 4 .

[0039] The sensor body 4 is fixedly mounted on the upper surface of the mounting plate 1 on the side opposite to the feed pipe 3 and the first mounting groove 13, and a reserved hole 11 is opened on the mounting plate 1 below the sensor body 4, so that the flipping of the guide plate 10 can be sensed through the reserved hole 11.

[0040] Furthermore, the sensor body 4 adopts a distance sensor structure design, the sensor body 4 is electrically connected to the controller body 6 through the connecting line 7, and the controller body 6 is electrically connected to the electric telescopic rod 5 through the connecting line 7.

[0041] By adopting a distance sensor structure design for the sensor body 4, and electrically connecting the sensor body 4 with the controller body 6 through the connecting line 7, and at the same time, the controller body 6 is electrically connected to the electric telescopic rod 5 through the connecting line 7, and then after programming the controller body 6, the number of grinding balls placed can be understood according to the number of flipping times of the guide plate 10 sensed by the sensor body 6, and the electric telescopic rod 5 can be controlled by the controller body 6, so that the guide plate 10 is limited by the limiting plate 9 installed at the bottom of the electric telescopic rod 5, so as to avoid the placement of more grinding balls.

[0042] Furthermore, a feeler rod 12 is fixedly mounted on the upper surface of the material guide plate 10 . The feeler rod 12 is located directly below the reserved hole 11 . The feeler rod 12 matches the sensor body 4 .

[0043] The feeler rod 12 is fixedly mounted on the upper surface of the guide plate 10 and is located directly below the reserved hole 11 . Meanwhile, the feeler rod 12 matches the sensor body 4 , thereby preventing the grinding balls from entering the guide plate 10 and affecting the sensor body 6 .

[0044] When the utility model is used, the mounting plate 1 is fixedly mounted at the medium inlet of the ball mill through the mounting hole 2, and the number of the inserted grinding balls is limited by programming the controller body 6.

After the grinding balls are inserted into the feed pipe 3, they contact the guide plate 10 and under the influence of gravity and the action of the spring hinge 8, the guide plate 10 is flipped under the mounting plate 1, and the grinding balls are placed in the ball mill. When the guide plate 10 is flipped, the touch rod 12 moves downward, so that the guide plate 10 is sensed to be flipped through the sensor body 4. Since the sensor body 4 is electrically connected to the controller body 6, it is determined that one grinding ball is inserted when the guide plate 10 is flipped once. When the number of inserted balls meets the production demand, the controller body 6 starts the electric telescopic rod 5, so that the limit plate 9 moves upward, thereby limiting the guide plate 10, thereby avoiding the insertion of more grinding balls.
