DETAILED DESCRIPTION

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] First embodiment:

[0022] See also Figures 1 to 3 ,in Figure 1 This is the overall structural diagram of the alumina semi-autogenous grinding return belt material secondary crushing equipment. Figure 2 This is a schematic diagram of the installation structure of the breaker hammer. Figure 3 yes Figure 2 Enlarged view of point A.

[0023] The present invention provides a secondary crushing device for alumina semi-autogenous grinding return belt material, comprising a conveyor belt 101 and a crushing assembly 102, wherein the crushing assembly 102 comprises a casing 103, a feed casing 104, a first screen plate 105, a drive motor 106, a rotor 107, a breaker hammer 108 and a dust removal component 109, the casing 103 comprises a shell 110, a liner 111 and a second screen plate 112, the dust removal component 109 comprises a water spray pipe 113, a protective cover 114 and an absorption component 115, through which the material discharged from the semi-autogenous grinding mill is introduced into the feed casing 104, so that the material enters the casing 103 along the feed casing 104, and the breaker hammer 108 is driven by the rotor 107 to rotate to crush larger materials, and the crushed materials fall on the conveyor belt 101 for transportation. It can be understood that the above scheme can be used for secondary crushing of materials discharged from the semi-autogenous grinding mill, and can also be used to solve the problem of removing dust generated by the crushed materials.

[0024] For this specific embodiment, the conveyor belt 101 is composed of conveyor rollers and belts, etc. The conveyor rollers are driven to rotate by an external driving device, and then the belts are driven to rotate to transport the materials. The conveyor belt 101 is a prior art and will not be described in detail here.

[0025] The housing 103 is connected to the conveyor belt 101 and is located on one side of the conveyor belt 101. The feed housing 104 is fixedly connected to the housing 103 and is arranged on the housing 103. The first sieve plate 105 is fixedly connected to the feed housing 104 and is located inside the feed housing 104. The drive motor 106 is connected to the housing 103 and is located on one side of the housing 103. The rotor 107 is rotatably connected to the housing 103 and is connected to the drive motor 106. The output end of the motor 106 is connected and located inside the housing 103. The breaker hammer 108 is rotatably connected to the rotor 107 and is arranged on the rotor 107. The dust removal component 109 is arranged on the housing 103. A plurality of breaker hammers 108 are provided and are evenly arranged on the rotor 107. The first screen plate 105 separates the feed housing 104 into a conveying chamber 116 and a discharge chamber 117. When in use, the material discharged from the semi-autogenous mill falls into the feed housing 104. After the material enters the conveying chamber 116, it moves along the first sieve plate 105. During the movement of the material, smaller materials can pass through the sieve holes on the first sieve plate 105 and enter the discharge chamber 117, and then be directly discharged to the conveyor belt 101 through the discharge chamber 117, thereby screening the material entering the casing 103, so that the smaller materials fall directly onto the conveyor belt 101. Due to their small size, the impact on the conveyor belt 101 is small, and direct discharge can improve the efficiency of conveying materials. The larger materials fall into the interior of the casing 103 along the first sieve plate 105, and the rotor 107 is driven to rotate by the drive motor 106, and then the rotor 107 drives the breaker hammer 108 to rotate. The larger materials are crushed by the rotation of multiple breaker hammers 108, so that the larger materials can fall on the conveyor belt 101 for transportation after being crushed, thereby achieving the purpose of preventing the conveyor belt 101 from being damaged by the impact of the materials.

[0026] Secondly, the shell 110 is connected to the conveyor belt 101, to the drive motor 106, and to the feed shell 104; the liner 111 is fixedly connected to the shell 110 and is located inside the shell 110; the second screen plate 112 is fixedly connected to the shell 110 and to the liner 111, and is arranged on the shell 110, and the second screen plate 112 is provided with sieve holes, and there are two liner plates 111, which are respectively located on the left and right sides of the second screen plate 112. Through the two liner plates 111, the material passes between the liner plate 111 and the breaker 108, and then the material is crushed by extrusion and collision. The smaller material can be discharged through the sieve holes on the second screen plate 112, while the larger material remains in the shell 110 and is continuously crushed until it can be discharged.

[0027] At the same time, the water spray pipe 113 is fixedly connected to the feed shell 104 and is located inside the feed shell 104; the protective cover 114 is fixedly connected to the feed shell 104 and is sleeved on the water spray pipe 113. The water spray pipe 113 is provided with multiple nozzles. When the material is crushed, the external water supply pipe is connected to the water spray pipe 113, so that the nozzle on the water spray pipe 113 can spray water, so that the water can adhere to the material, reducing the dust generated when the material is crushed. At the same time, the protective cover 114 can protect the water spray pipe 113 to prevent the material from colliding with the water spray pipe 113 when entering the feed shell 104, causing damage to the water spray pipe 113.

[0028] When using the alumina semi-autogenous grinding return belt material secondary crushing equipment of this embodiment, the material burst out of the semi-autogenous grinding mill first enters the feed shell 104, and is screened by the first screen plate 105 so that smaller materials can fall on the conveyor belt 101, while larger materials enter the shell 110, and the rotor 107 and the breaker 108 are driven by the drive motor 106 to rotate to crush the larger materials. The crushed materials finally pass through the second screen plate 112 and fall on the conveyor belt 101, thereby preventing larger materials from causing a greater impact on the conveyor belt 101, causing damage to the conveyor belt 101. The utility model solves the problem of preventing materials from impacting the conveyor belt 101 and causing damage to the conveyor belt 101 by performing secondary crushing on the materials.

[0029] Second embodiment:

[0030] Based on the first embodiment, please refer to Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the installation structure of the filter screen of the second embodiment. Figure 52 is a schematic diagram of the installation structure of the barrier net of the second embodiment. The absorption component 115 of this embodiment also includes a fan 201, a collection box 202, a filter net 203 and a barrier net 204.

[0031] According to this specific embodiment, the collection box 202 is fixedly connected to the shell 110, is located on one side of the shell 110, and is connected to the shell 110 through a pipe; the fan 201 is fixedly connected to the shell 110, is located on a side of the shell 110 close to the collection box 202, and is connected to the collection box 202; the filter 203 is fixedly connected to the collection box 202, and is located inside the collection box 202. The air and dust inside the collection box 202 and the shell 110 are extracted by the fan 201, and the air and dust enter the collection box 202 through a pipe. Under the filtration of the filter 203, the dust remains inside the collection box 202 for collection, and the air can be discharged through the filter 203, thereby further reducing the dust generated when the material is crushed, and preventing the dust from floating around and affecting the working environment and workers' health.

[0032] Among them, the blocking net 204 is fixedly connected to the shell 110 and is arranged on the shell 110. The blocking net 204 blocks the material to prevent the crushed material from entering the pipe connecting the collection box 202 and the shell 110, causing the pipe to be blocked and affecting the absorption of dust.

[0033] The above disclosure is merely one or more preferred embodiments of the present application and is not intended to limit the scope of the present application. A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
