Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a ball mill powder discharge filtration device. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. They are mainly used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, metal ore beneficiation, and glass ceramics. Ball mills can be divided into two types according to the discharge method: grate type and overflow type. They can also be divided into two grinding methods: dry and wet. They are suitable for powdered ore and other materials and are widely used in mineral beneficiation, construction and chemical industries.

[0003] Chinese Patent CN219334410U discloses a ball mill, the key points of which are: It relates to the field of grinding and aims to solve the problem of uneven particle size distribution in the ground material due to the inconsistent positions of steel balls during cylinder rotation, resulting in some materials being ground more heavily than others. The mill includes a support frame and a cylinder. One end of the cylinder has an inlet, and the outer peripheral wall has an outlet. Both ends of the cylinder are rotatably mounted on the support frame. Several steel balls are placed inside the cylinder. A drive motor is mounted on the support frame to drive the cylinder's rotation. An inner cylinder is located inside the cylinder, with its two ends along its length attached to the cylinder. The inner cylinder has several sieve holes. This application effectively improves the uniformity of the ground material particles.

[0004] The existing technical solutions described above have the following drawbacks: although the technical solutions can improve the uniformity of the material particles after grinding, they only collect the ball-milled material by using a collection box and cannot filter the ball-milled material. This can easily cause materials of different sizes to be mixed together, which can easily affect the subsequent processing of the material. Utility Model Content

A through-hole 5 is provided at the middle of the bottom surface of the filter box 3. A limiting rod 8 is provided on one side of the filter box 3, penetrating the side surface of the receiving box 1. A return spring 9 is sleeved on the outer surface of the limiting rod 8 between the receiving box 1 and the filter box 3. A push rod 6 is provided on one side of the filter box 3, penetrating the side surface of the receiving box 1. A side plate 14 is provided on one side of the receiving box 1, and a motor 15 is installed on the bottom surface of the side plate 14. A cam 13 is fixedly connected to the output end of the motor 15 through the side plate 14. Electric push rods 18 are installed on both sides of the rear end surface of the receiving box 1, and the output end of the electric push rods 18 penetrates the receiving box. A pusher plate 10 is fixedly connected to the rear end surface of the receiving box 1. The receiving box 1 is moved to the bottom of the ball mill outlet. The material after ball milling can be collected by using the receiving box 1. When the material falls into the filter box 3 in the receiving box 1, the motor 15 on the bottom surface of the side plate 14 is opened. The motor 15 drives the cam 13 to rotate. While the cam 13 is rotating, it drives the push rod 6 on one side surface of the filter box 3 to move. With the use of the limit rod 8 and the return spring 9, the filter box 3 can move back and forth in the receiving box 1. The material can be filtered by using the screen 4. The material of uniform size falls to the bottom of the receiving box 1, and the larger material stays on the screen 4, which facilitates the subsequent processing of the filtered material.

[0030] In one embodiment, the cam 13 is matched with the push rod 6, which facilitates the movement of the filter box 3 at one end of the push rod 6, thereby enabling the filter box 3 to move back and forth in the receiving box 1, which improves the filtration effect on the material.

[0031] In one embodiment, a protective shell 12 is provided on the surface of the receiving box 1 outside the side plate 14 and the push rod 6, and a maintenance plate 17 is fixedly connected to the front surface of the protective shell 12 by screws. The maintenance plate 17 can be removed by loosening the screws, thereby facilitating the maintenance and repair of the components in the protective shell 12.

[0032] In one embodiment, a handle 7 is provided on one side of the top surface of the protective shell 12, wherein the device can be moved by the cooperation of the handle 7 and the roller 11, thereby improving the flexibility of the device.

[0033] In one embodiment, baffles 2 are provided on both sides of the top surface of the receiving box 1. By using the baffles 2, the ball-milled material can be guided so that the material can accurately enter the filter box 3, thereby facilitating the filtration of the ball-milled material.

[0034] In one embodiment, the front surface of the receiving bin 1 is hinged with a door 16, which allows the material in the receiving bin 1 to be discharged by opening the door 16.

[0035] In one embodiment, rollers 11 are provided on both sides of the bottom surface of the receiving box 1, which allows the device to be moved by using the rollers 11, thereby improving the flexibility of the device.

[0036] In one embodiment, guide plates are inclined on both sides of the bottom upper surface of the filter box 3. By using the guide plates, the material in the filter box 3 can be guided to prevent it from remaining at the bottom of the filter box 3, thereby facilitating the discharge of the filtered material.

[0037] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0038] Working principle:

[0039] In use, the receiving box 1 is moved below the ball mill outlet. The receiving box 1 collects the milled material. When the material falls into the filter box 3 within the receiving box 1, the motor 15 on the bottom surface of the side plate 14 is activated. The motor 15 drives the cam 13 to rotate, which in turn moves the push rod 6 on one side surface of the filter box 3. Through the use of the limit rod 8 and the return spring 9, the filter box 3 moves back and forth within the receiving box 1. The screen 4 filters the material, allowing uniformly sized material to fall to the bottom of the receiving box 1. Larger materials remain on the screen 4, facilitating subsequent processing of the filtered material. The filtered material can be discharged by opening the door 16. The electric push rod 18 on the rear surface of the receiving box 1 drives the push plate 10 to move. The use of the push plate 10 automatically pushes out the filtered material from the bottom of the receiving box 1, preventing material residue at the bottom of the receiving box 1, thus facilitating material discharge and improving its practicality. The use of rollers 11 and handles 7 allows the receiving box 1 to move, improving its flexibility and making it convenient to use.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
