Description

Technical Field

[0001] The utility model relates to the technical field of cone crushers, and particularly relates to a dust reduction device for the inner cavity of a cone crusher. Background Technique

[0002] A cone crusher is a crushing device widely used in multiple fields such as mining, smelting, building materials, highways, railways, water conservancy, and chemical industries. It is mainly used for medium crushing and fine crushing of various ores and rocks. When the crusher works, materials are fed from above, and after being crushed in the crushing cavity, they are discharged into the inner cavity of the crusher through the discharge port and then discharged to the next process through the ore collecting port. A large amount of dust is generated during this process.

[0003] At present, a spraying device is usually arranged at the feeding port of the cone crusher to pre-spray the ore, and the surface of the material is wetted to reduce the generation of dust during the crushing process, so as to avoid a large amount of dust filling the inside (inner cavity) of the crusher. However, since only the surface of the original stone is wetted, dust will still be released inside the crushed material, resulting in dust still filling the inner cavity. To solve the internal dust problem, another technical solution is to directly install the nozzle inside the inner cavity of the crusher for spraying and dust reduction. However, in the long-term operation, the surface of the nozzle is extremely easy to be covered by dust and then blocked. More importantly, due to the nozzle being located in the narrow space inside the crusher, its inspection, cleaning, and replacement operations become very difficult and inconvenient. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dust reduction device for the inner cavity of a cone crusher, which solves the problems of dust filling in the inner cavity of the existing cone crusher due to incomplete dust reduction, as well as the easy blockage and difficult maintenance of the built-in nozzle.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model provides a dust reduction device for the inner cavity of a cone crusher, which includes a housing. The housing is installed on the upper surface of the machine body. A cover plate is installed on the upper surface of the housing. A plurality of mounting holes are opened on the lower surface of the housing. A drain pipe is installed inside the mounting hole. One end of the drain pipe extends into the interior of the machine body. A connecting pipe is provided at one end of the housing. The other end of the connecting pipe is installed with a water inlet pipe. A plurality of control components are arranged inside the housing. The control component includes a housing body. The housing body is installed on the lower surface of the cover plate. A plate body is installed on the lower surface of the housing body. A connecting rod is slidably connected inside the housing body. The lower end of the connecting rod penetrates through the plate body and is installed with a baffle plate.

[0007] Furthermore, the number of the control components corresponds to the drain pipes one by one. One end of the connecting rod is located inside the drain pipe, and the upper surface of the baffle plate abuts against the lower surface of the drain pipe.

[0008] Further, a slider is installed at the upper end of the connecting rod, and the slider is slidably connected inside the housing.

[0009] Further, a spring is installed on the upper surface of the slider, and the other end of the spring is installed at the inner top of the housing.

[0010] Further, an auxiliary groove is formed on the inner surface of the housing, an auxiliary block is arranged on the outer surface of the slider, and the auxiliary block is slidably connected inside the auxiliary groove.

[0011] Further, a control valve is installed on the outer surface of the connecting pipe.

[0012] The utility model has the following beneficial effects:

[0013] (1) By accurately laying the drain pipe in the annular protection area between the machine body and the fixed cone, the utility model uses the natural barrier formed by the two to isolate the impact of the ore falling in the crushing cavity, which not only ensures the safety of the drain pipe but also realizes the dust source coverage. At the same time, a control component driven by water pressure is adopted. When water passes through, the water pressure jacks up the control component to start spraying, and when the water is cut off, the control component automatically resets to seal the pipe orifice, avoiding the blockage risk caused by the long-term exposure of the traditional built-in nozzle. During maintenance, only need to loosen the shell bolts and vertically lift the shell, then all the drain pipes can be safely pulled out from the protection area of the machine body synchronously, achieving the effect of being easy to replace.

[0014] (2) By the cooperative use of the auxiliary groove and the auxiliary block, the utility model restricts the slider to slide only in the vertical direction, eliminates the axial rotation tendency of the connecting rod, and ensures that the baffle plate always keeps a uniform full-circumference fit with the lower end surface of the drain pipe.

[0015] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Please refer to Figures 1-5 As shown, the present utility model is a dust reduction device for the inner chamber of a cone crusher, including an outer shell 1, the outer shell 1 is installed on the upper surface of the machine body 8, the upper surface of the outer shell 1 is installed with a cover plate 2, several mounting holes are opened on the lower surface of the outer shell 1, a drain pipe 3 is installed inside the mounting holes, one end of the drain pipe 3 extends into the machine body 8, one end of the outer shell 1 is provided with a connecting pipe 4, the other end of the connecting pipe 4 is installed with a water inlet pipe 5, and several control components 6 are arranged inside the outer shell 1. The control component 6 includes a housing 601, the housing 601 is installed on the lower surface of the cover plate 2, a plate body 602 is installed on the lower surface of the housing 601, a connecting rod 603 is slidably connected inside the housing 601, and the lower end of the connecting rod 603 penetrates through the plate body 602 and is installed with a baffle 604;

[0026] A main shaft 9 and a fixed cone 10 are installed inside the machine body 8, a moving cone 11 is installed on the outer surface of the main shaft 9, a crushing chamber is formed by the cooperation of the moving cone 11 and the fixed cone 10, and the drain pipe 3 is located between the machine body 8 and the fixed cone 10;

[0027] By precisely arranging the drainage pipe 3 in the annular protection zone between the machine body 8 and the fixed cone 10, the natural barrier formed by the two is used to isolate the impact of the ore falling in the crushing chamber, which not only ensures the safety of the drainage pipe 3 but also achieves the coverage of the dust source. At the same time, a water pressure-driven control component 6 is adopted. When water is flowing, the water pressure lifts the control component 6 to start spraying. When the water is cut off, the control component 6 automatically resets the sealed pipe mouth, avoiding the risk of blockage caused by long-term exposure of traditional built-in sprinklers. During maintenance, only the bolts of the outer shell 1 need to be loosened and the outer shell 1 lifted vertically to simultaneously and safely pull out all the drainage pipes 3 from the protection zone of the machine body 8, achieving the effect of easy replacement.

[0028] The number of control components 6 corresponds to the number of drain pipes 3. One end of the connecting rod 603 is located inside the drain pipe 3. The upper surface of the baffle 604 abuts against the lower surface of the drain pipe 3.

[0029] A slider 605 is installed on the upper end of the connecting rod 603 , and the slider 605 is slidably connected to the inside of the housing 601 .

[0030] A spring 606 is mounted on the upper surface of the slider 605, and the other end of the spring 606 is mounted on the inner top of the housing 601;

[0031] An auxiliary groove 607 is formed on the inner surface of the housing 601, and an auxiliary block 608 is formed on the outer surface of the slider 605. The auxiliary block 608 is slidably connected to the inside of the auxiliary groove 607.

[0032] The auxiliary groove 607 and the auxiliary block 608 cooperate to constrain the slider 605 to slide only in the vertical direction, eliminating the axial rotation tendency of the connecting rod 603 and ensuring that the baffle 604 always maintains a uniform fit around the lower end surface of the drain pipe 3.

[0033] A control valve 7 is installed on the outer surface of the connecting pipe 4 .

[0034] When in use, first connect the water inlet pipe 5 to the external water supply system, then turn on the main shaft 9 to drive the moving cone 11 to rotate, and put stones into the machine body 8, so that the stones enter the crushing chamber for crushing. During the crushing process, the control valve 7 and the water supply equipment are started synchronously, and water flows through the water inlet pipe 5 and the connecting pipe 4 into the outer shell 1, and then flows into the drain pipe 3. The water pressure pushes the baffle 604 downward, driving the connecting rod 603 and the slider 605 to overcome the resistance of the spring 606 and slide downward, so that the baffle 604 is separated from the outlet of the drain pipe 3, and the water flow is immediately sprayed into the crusher to achieve source dust suppression. After the operation is completed, the water source and the control valve 7 are closed, the water pressure in the drain pipe 3 drops, the spring 606 resets and pushes the slider 605 upward, and the linkage baffle 604 reseals the lower end of the drain pipe 3 to isolate dust from invading the drain pipe 3;

[0035] By precisely arranging the drainage pipe 3 in the annular protection area between the machine body 8 and the fixed cone 10, the natural barrier formed by the two is used to isolate the impact of the falling ore in the crushing chamber, which not only ensures the safety of the drainage pipe 3 but also achieves coverage of the dust source. At the same time, a water pressure-driven control component 6 is adopted. When water is passed, the water pressure lifts the control component 6 to start spraying. When the water is cut off, the control component 6 automatically resets the sealed pipe mouth, avoiding the risk of blockage caused by long-term exposure of traditional built-in sprinklers. During maintenance, it is only necessary to loosen the bolts of the outer shell 1 and lift the outer shell 1 vertically, and all the drainage pipes 3 can be safely pulled out from the protection area of the machine body 8 at the same time, so that replacement is easy.
