Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically a protective device for a water-jacketed ball mill. Background Technology

[0002] Ball mills are key pieces of equipment for further pulverizing materials after they have been crushed. This type of grinding mill uses a certain number of steel balls as grinding media inside its cylinder. It is widely used in industries such as cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, and glass and ceramics production 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 mineral processing, building materials, and chemical industries. They can be divided into dry and wet grinding methods. Depending on the discharge method, they can be divided into grate type and overflow type. However, ball mills require protective devices to protect the cylinder during operation.

[0003] However, existing water-jacketed ball mills require high-speed operation during operation. At this time, the steel balls and materials inside the mill collide with the water-jacketed ball mill, generating significant noise. Simultaneously, the collision of steel balls and materials with the water-jacketed ball mill also generates heat. Because the water-jacketed ball mill cannot effectively absorb or block noise or insulate against heat, this leads to noise pollution affecting operators and the surrounding environment, as well as burns to operators who come into contact with the high-temperature surface of the mill. Therefore, we propose a protective device for water-jacketed ball mills. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a protective device for water-jacketed ball mills, thereby solving the problems mentioned in the background art, such as the inability of water-jacketed ball mills to effectively absorb and block noise and insulate heat, resulting in noise affecting operators and the surrounding environment, and burns to operators when in contact with the high-temperature surface of the cylinder.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a protective device for a water-jacketed ball mill, comprising a protective unit and an installation assembly, wherein the protective unit includes a protective liner, a protective pad is fixedly connected to the bottom of the protective liner, an installation groove is formed between the bottom center of the protective liner and the protective pad, a sound insulation plate is fixedly connected to the inner side of the installation groove, a heat insulation plate is fixedly connected to the bottom of the sound insulation plate, an installation plate is fixedly connected to the bottom of the heat insulation plate, and an installation opening is formed at the top of the protective liner;

[0008] The mounting assembly includes a mounting bolt located inside the mounting port, with a limiting washer fixedly connected to the top of the mounting bolt.

[0009] Preferably, the top of the protective pad, mounting plate, sound insulation plate and heat insulation plate are all provided with an opening, and the opening is movably connected to the mounting bolt.

[0010] Preferably, the protective pad is made of rubber material and is located at the bottom of the mounting plate.

[0011] Preferably, the sound insulation panel is made of fiberglass material and is located inside the mounting groove.

[0012] Preferably, the heat insulation board is made of ceramic material and has a solid structure.

[0013] Preferably, a washer is movably connected to the outer side of the bottom end of the mounting bolt, and a nut sleeve is threadedly connected to the outer side of the bottom end of the mounting bolt below the washer.

[0014] Preferably, the diameter of the mounting bolt is adapted to the inner diameter of the mounting opening and the through opening, and the mounting bolt passes through the mounting opening and the through opening.

[0015] (III) Beneficial Effects

[0016] This utility model provides a protective device for a water-jacketed ball mill, which has the following beneficial effects:

[0017] (1) The protective device of this water-jacketed ball mill, through the installation of protective pads, sound insulation plates, and heat insulation plates, allows the operator to install the protective liner on the inner wall of the ball mill cylinder, ensuring the protective pad fits snugly against the inner wall. Then, the operator inserts the mounting bolts through the mounting opening and through-hole, then through the ball mill cylinder, and installs the gasket and nut sleeve. Finally, the nut sleeve is tightened, and the protective device is firmly fixed to the inner wall of the ball mill cylinder. When processing materials, the materials and steel balls collide with the protective liner, generating heat. Because the heat insulation plate is made of ceramic material, it effectively provides heat insulation. The sound insulation panel, made of fiberglass, effectively absorbs and blocks noise transmission when collisions occur, preventing heat transfer to the ball mill cylinder. The protective pad, made of rubber, utilizes the numerous tiny pores and elastic structure within the rubber material to repeatedly reflect, refract, and absorb sound waves, gradually weakening their energy. This enhances the protective effect of the water-jacketed ball mill's protective device, enabling it to effectively insulate against heat and reduce noise, preventing noise from affecting operators and the surrounding environment, and reducing the risk of burns to operators.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: A protective device for a water-jacketed ball mill includes a protective unit 1 that protects the ball mill cylinder, comprising a protective liner 101, a vibration-damping and noise-reducing protective pad 102 fixedly connected to the bottom of the protective liner 101, an installation groove 103 for installing protective components being provided between the bottom center of the protective liner 101 and the protective pad 102, a sound insulation plate 105 for sound insulation and noise reduction being fixedly connected to the inner side of the installation groove 103, a heat insulation plate 106 for isolating heat source transmission being fixedly connected to the bottom of the sound insulation plate 105, and an installation plate 104 for compacting the sound insulation plate 105 and the heat insulation plate 106 being fixedly connected to the bottom of the heat insulation plate 106, and an installation port 107 for assembling installation bolts 201 being provided at the top of the protective liner 101.

[0026] Furthermore, the top of the protective pad 102, mounting plate 104, sound insulation plate 105 and heat insulation plate 106 are all provided with openings 108 for mounting bolts 201, and the openings 108 are movably connected to the mounting bolts 201.

[0027] Furthermore, the protective pad 102 is made of rubber material and is located at the bottom of the mounting plate 104.

[0028] Furthermore, the sound insulation panel 105 is made of fiberglass material and is located inside the mounting groove 103.

[0029] Furthermore, the heat insulation plate 106 is made of ceramic material and has a solid structure.

[0030] As can be seen from the above, when the material is being processed, the material and steel balls will collide with the protective liner 101 and generate heat. Since the heat insulation plate 106 is made of ceramic material, the heat insulation plate 106 will play a heat insulation role by utilizing its own properties, effectively blocking the heat from being transferred to the ball mill cylinder.

[0031] Furthermore, when a collision generates noise, the sound insulation panel 105, being made of fiberglass material, effectively absorbs and blocks the transmission of noise by utilizing the properties of its material.

[0032] Furthermore, by utilizing the protective pad 102, which is made of rubber material, the rubber material has a large number of tiny pores and elastic structure. When sound waves propagate into the rubber material, some of the sound wave energy will be repeatedly reflected, refracted and absorbed in the pores, thereby gradually weakening the energy of the sound waves.

[0033] Example 2: This example is basically the same as the previous example, except that the mounting component 2 used for installation and fixing includes a mounting bolt 201 for fixing located inside the mounting port 107, and a limiting pad 204 for restricting the movement of the mounting bolt 201 is fixedly connected to the top of the mounting bolt 201.

[0034] Furthermore, a washer 202 for filling the gap between the two components is movably connected to the outer side of the bottom end of the mounting bolt 201, and a nut sleeve 203 for fixing the mounting bolt 201 is threadedly connected to the outer side of the bottom end of the mounting bolt 201 below the washer 202.

[0035] Furthermore, the diameter of the mounting bolt 201 is adapted to the inner diameter of the mounting port 107 and the through port 108, and the mounting bolt 201 passes through the mounting port 107 and the through port 108.

[0036] As shown above, the protective liner 101 is installed on the inner wall of the ball mill cylinder, so that the protective pad 102 fits against the inner wall of the ball mill cylinder. Then, the operator inserts the mounting bolt 201 through the mounting port 107 and the through port 108, and then inserts it through the ball mill cylinder. The gasket 202 and the nut sleeve 203 are then installed and tightened. At this time, the protective device will be firmly fixed on the inner wall of the ball mill cylinder. In order to make the protective device fit better with the inner wall of the ball mill cylinder, the overall curvature of the protective device can be adjusted appropriately to facilitate installation. This scheme is not illustrated.
