DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-5 As shown, a sliding ball mill grinding head sealing device includes a ball mill 1 and a base 11. The ball mill 1 is fixedly connected to an oil retaining ring 2 at the middle of the left and right ends. The upper right side of the base 11 is fixedly connected to a motor 3. The outer surface of the output end of the motor 3 is fixedly connected to a transmission mechanism 7. The output end of the motor 3 is fixedly connected to a knocking mechanism 5. The lower front side of the transmission mechanism 7 is fixedly connected to a rotating mechanism 6. The upper left side of the base 11 is fixedly connected to a feeding mechanism 4.

[0025] During the specific implementation of the above device, the two oil retaining rings 2 cooperate with the ball mill 1 to prevent the sliding shoe of the ball mill 1 from seriously penetrating the lubricating oil during actual operation. Secondly, the feeding mechanism 4 is cooperated with the feeding length to avoid leakage, dust emission or failure to ventilate in time near the feeding port of the grinding head of the ball mill 1 during operation.

[0026] Similarly, the motor 3, transmission mechanism 7 and knocking mechanism 5 cooperate to avoid blockage during the feeding process. Secondly, the rotating mechanism 6 and the feeding mechanism 4 cooperate to ventilate the inside of the ball mill 1 and avoid dust emission during the operation of the ball mill 1.

[0027] The ball mill 1 mentioned above is of conventional design in the prior art, and its working principle will not be described in detail in this solution.

[0028] See Figure 3 and Figure 5The feeding mechanism 4 includes a feeding pipe 42 fixedly connected to the middle of the left end of the ball mill 1, and the upper end of the feeding pipe 42 is fixedly connected to the feeding hopper 41.

[0029] Specifically, when the above device is in operation, the clinker to be ground is slowly and orderly put into the feed hopper 41, and then enters the inner surface of the feed pipe 42 through the feed hopper 41, and then enters the inner surface of the ball mill 1 for grinding.

[0030] See Figure 5 A rectangular opening 421 is provided on the upper portion of the outer surface of the feed pipe 42 near the left end of the ball mill 1. A plurality of baffles 422 are fixedly connected to the front side wall and the rear side wall of the inner surface of the rectangular opening 421. A filter screen 423 is fixedly connected to the upper portion of the outer surface of the rectangular opening 421, and the baffles 422 are arranged in an inclined shape.

[0031] Specifically, when the ball mill 1 is in operation, the inclined setting of the baffle 422 can prevent dust from escaping from the feed port at the left end of the ball mill 1 during the ball milling process, thereby improving the environmental problems surrounding the ball mill 1 during operation.

[0032] See Figure 4 The transmission mechanism 7 includes a driving wheel 71 fixedly connected to the outer surface of the output end of the motor 3, a conveyor belt 72 is wrapped around the middle of the outer surface of the driving wheel 71, and a driven wheel 73 is wrapped around the inner surface of the lower part of the conveyor belt 72.

[0033] Specifically, when the above-mentioned device is in operation, the output end of the motor 3 drives the driving wheel 71 to rotate, and at the same time, the transmission belt 72 and the driven wheel 73 cooperate with each other so that when the driving wheel 71 rotates, the transmission belt 72 and the driven wheel 73 rotate at the same time to transmit power.

[0034] See Figure 4 and Figure 5 The rotating mechanism 6 includes a rotating shaft 61 whose outer surface is fixedly connected to the inner surface of the driven wheel 73, and a plurality of rectangular plates 62 are fixedly connected to the front annular array of the outer surface of the rotating shaft 61.

[0035] Furthermore, when the driven wheel 73 is driven to rotate, the driven wheel 73 can drive the rotating shaft 61 to rotate, thereby causing the plurality of rectangular plates 62 to rotate simultaneously, and the simultaneous rotation of the plurality of rectangular plates 62 drives the surrounding gas flow;

[0036] Through the cooperation of the filter screen 423, part of the driven air flow will enter the inner surface of the rectangular opening 421 and then enter the inner surface of the ball mill 1, while ventilating the inner surface of the ball mill 1. At the same time, the baffle 422 can prevent dust from escaping during the ball milling process on the left end of the inner surface of the ball mill 1.

[0037] See Figure 5, the lower end of a rectangular plate 62 contacts the upper end of the filter screen 423.

[0038] Furthermore, when the plurality of rectangular plates 62 are rotated by the rotating shaft 61 , the surrounding gas is driven to flow, and the flowing gas is continuously allowed to enter the inner surface of the ball mill 1 through the rectangular opening 421 , continuously ventilating the inner surface of the ball mill 1 .

[0039] See Figure 3 The knocking mechanism 5 includes a rotating plate 51 fixedly connected to the output end of the motor 3, a rotating rod 52 is fixedly connected to one side of the front end of the rotating plate 51, a limiting ring 53 is provided on the outer surface of the rotating rod 52, and a push rod 54 is fixedly connected to the left middle part of the outer surface of the limiting ring 53.

[0040] Specifically, when the above device is in operation, the motor 3 rotates to drive the rotating plate 51 to rotate, thereby driving the rotating rod 52 to rotate by the rotating plate 51. At the same time, since the rotating rod 52 is located on one side of the front end of the rotating plate 51, when the rotating plate 51 rotates, the rotating rod 52 rotates around the axis of the rotating plate 51. At the same time, during the rotation of the rotating rod 52, the outer surface of the rotating rod 52 is always in contact with the inner surface of the limiting ring 53. When the rotating rod 52 rotates around the axis of the rotating plate 51, it drives the limiting ring 53 to move left and right. Similarly, the limiting ring 53 drives the push rod 54 to move left and right.

[0041] During the left and right movement of the push rod 54, when the push rod 54 moves to the maximum right position, the right end of the push rod 54 just contacts the outer surface of the feed pipe 42. At this time, the push rod 54 knocks on the feed pipe 42 to prevent the clinker on the inner surface of the feed pipe 42 from being blocked when it slides down into the inner surface of the ball mill 1. When the ball mill 1 continues to ball mill and continuously feeds it, the push rod 54 is continuously driven to move left and right, thereby knocking on the outer surface of the feed pipe 42, causing the feed pipe 42 to vibrate, thereby preventing its inner surface from being blocked.

[0042] It should be noted that the specific installation method of the motor 3, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
