Description
Technical Field
[0001] This utility model belongs to the technical field of crushers, and specifically relates to a crusher with a dust removal device. Background Technique
[0002] In many industrial fields, the crushing and dust removal of materials are common operations. For example, in industries such as mineral processing, chemical production, pharmaceuticals, and food processing, raw materials need to be crushed into smaller particles to meet the requirements of subsequent processes. However, during the material crushing process, a large amount of dust and impurities will be generated. If not effectively treated, these dust and impurities will not only pollute the working environment but may also pose a hazard to the health of operators.
[0003] Traditional crushers usually only focus on the crushing function of materials and pay insufficient attention to the dust removal effect. This may lead to dust flying, polluting the air, and it is difficult to meet the increasingly strict environmental protection requirements. In addition, some materials may contain stubborn impurities, which are difficult to remove during the crushing process and affect product quality.
[0004] In the existing technology, some crushers may be equipped with simple dust removal equipment, such as bag filters or electrostatic precipitators. However, these devices often have problems such as low dust removal efficiency, easy clogging, or high maintenance costs. In addition, for the cleaning of stubborn impurities, existing crushers may lack effective means, resulting in impurity residues and affecting product purity.
[0005] Therefore, we propose a crusher with a dust removal device, which can not only remove dust from the crushed materials but also clean some stubborn impurities, improving the dust removal effect. Content of the Utility Model
[0006] The purpose of this utility model is to provide a crusher with a dust removal device, which can not only remove dust from the crushed materials but also clean some stubborn impurities, improving the dust removal effect.
[0007] The technical solutions adopted by this utility model are specifically as follows:
[0008] A crusher with a dust removal device includes a cylinder body, which is composed of a first conical shell, a cylindrical shell, and a second conical shell. And a rotating assembly is arranged inside the cylinder body. A conical crushing cone located inside the first conical shell, a first impurity removal component located inside the cylindrical shell, and a second impurity removal component located inside the second conical shell are arranged on the rotating assembly;
[0009] A plurality of support plates are arranged on the outer side of the cylinder body. A hollow shell is arranged on each support plate. A filter plate is arranged inside the hollow shell. A dust suction pipe located inside the cylinder body is arranged on one side of the hollow shell. And a protective shell communicated with the hollow shell is installed on the other side of the hollow shell. An air guiding component is arranged inside the protective shell.
[0010] Further, first crushing teeth are arranged on the inner wall of the first conical shell, and second crushing teeth are arranged on the outer side of the conical crushing cone.
[0011] Further, the rotating component includes a first motor arranged on the top of the cylinder body. A rotating shaft is installed at the output end of the first motor. The bottom of the rotating shaft penetrates through the cylinder body.

[0025] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present utility model, and does not strictly limit the scope of protection of the specific claims of the present utility model.
[0026] As Figures 1-4 shown, the technical solution adopted by the present utility model is specifically as follows: A crusher for a dust removal device, including a cylinder body 1, the cylinder body 1 is composed of a first conical housing 2, a cylindrical housing 3 and a second conical housing 4, and a rotating assembly is arranged inside the cylinder body 1, and a conical crushing cone 5 located inside the first conical housing 2, a first impurity removal assembly located inside the cylindrical housing 3 and a second impurity removal assembly located inside the second conical housing 4 are arranged on the rotating assembly;
[0027] A plurality of support plates 6 are arranged on the outer side of the cylinder body 1, a hollow housing 7 is arranged on each support plate 6, a filter plate 8 is arranged inside the hollow housing 7, a dust suction pipe 9 located inside the cylinder body 1 is arranged on one side of the hollow housing 7, and a protective housing 10 communicated with the hollow housing 7 is installed on the other side of the hollow housing 7, and an air guiding assembly is arranged inside the protective housing 10.
[0028] Its working principle is as follows: First, the material enters the first conical shell 2 inside the cylinder body 1, and then the rotating assembly drives the conical crushing cone 5 to rotate, so that the material is frictionally extruded with the inner wall of the first conical shell 2 for crushing. During the crushing process, dust is generated inside the cylinder body 1. At this time, the air guiding assembly provides power to make the dust suction pipe 9 suck the dust and impurities inside the cylinder body 1. The sucked impurities enter the inside of the hollow shell 7, and then pass through the filtration of the filter plate 8, so that the clean air is discharged through the protective shell 10, while the impurities stay inside the hollow shell 7 waiting to be cleaned. At the same time, there will be some impurities that are difficult to adsorb remaining on the crushed impurities. If these impurities are not cleaned, the external dust will fly due to gravity when discharging. Therefore, when the crushed material moves to the cylindrical shell 3 by gravity, the rotating assembly drives the first impurity cleaning assembly to rotate, so as to clean the impurities on the moving material. Then the crushed material enters the second conical shell 4, and the rotating assembly drives the second impurity removal assembly to clean the impurities on the moving material again. During the cleaning process, the impurity dust is led out and collected through the air guiding assembly. This device can not only remove dust from the crushed material, but also clean some stubborn impurities, improving the dust removal effect.
[0029] Among them, first crushing teeth 11 are arranged on the inner wall of the first conical shell 2, and second crushing teeth 12 are arranged on the outside of the conical crushing cone 5. The entering material can be crushed by the first crushing teeth 11 and the second crushing teeth 12.
[0030] At the same time, the distance between the conical crushing cone 5 and the first conical shell 2 is getting smaller and smaller, so that the crushing effect of the crushed material can meet the specifications.
[0031] As Figure 2 shown, the rotating assembly includes a first motor 13 arranged at the top of the cylinder body 1. A rotating shaft 14 is installed at the output end of the first motor 13. The bottom of the rotating shaft 14 penetrates the cylinder body 1, and the first motor 13 drives the rotating shaft 14 to rotate.
[0032] As Figure 3 shown, the first impurity removal assembly includes a cylindrical disc 15 sleeved on the rotating shaft 14. A plurality of connecting plates are arranged on the outside of the cylindrical disc 15. A first impurity removal brush 16 is arranged on one side of each connecting plate. When the rotating shaft 14 rotates, it drives the cylindrical disc 15 to make the connecting plates rotate. The connecting plates drive the first impurity removal brush 16 to rotate and contact the crushed material. When contacting, the first impurity removal brush 16 removes the impurities adhering to the crushed material, thereby improving the dust removal effect.
[0033] Among them, a first conical guide plate is arranged at the top of the cylindrical disc 15. The first conical guide plate can guide the crushed material, so that the material can be quickly discharged.
[0034] It should be noted that when the crushed material contacts the first impurity removal brush 16, friction will be generated between the crushed material and the first impurity removal brush 16. At the same time, the first impurity removal brush 16 also has a rotational force, which acts on the material, equivalent to moving for impurity removal. And the impurity removal brush is soft in nature. When it contacts the material, it will move on the material, thereby removing impurities.
[0035] As Figure 3 shown, the second impurity removal component includes a conical disk 17 sleeved on the rotating shaft 14. A plurality of second impurity removal brushes 18 are arranged on the outer side of the conical disk 17. When the rotating shaft 14 rotates, it drives the conical disk 17 to rotate, and the conical disk 17 drives the second impurity removal brushes 18 to remove impurities on the crushed material.
[0036] Among them, a second conical guide plate is arranged at the top of the conical disk 17. Through the second conical guide plate, the crushed plastic can be guided, so that the material can be quickly discharged.
[0037] It should be noted that when the crushed material contacts the second impurity removal brush 18, friction will be generated between the crushed material and the second impurity removal brush 18. At the same time, the second impurity removal brush 18 also has a rotational force, which acts on the material, equivalent to moving for impurity removal. And the impurity removal brush is soft in nature. When it contacts the material, it will move on the material, thereby removing impurities
[0038] At the same time, the distance between the conical disk 17 and the second conical shell 4 is the same. Such a setting can discharge the materials that meet the specifications, and the materials that do not meet the specifications will be extruded again to meet the specifications.
[0039] As Figure 4 shown, the air induction component includes a bracket arranged inside the protective shell 10. A second motor 19 is arranged on the bracket. A fan blade 20 is installed at the output end of the second motor 19. The second motor 19 drives the fan blade 20 to rotate, thereby achieving the effect of providing power for air induction.
[0040] In order to enable the material to enter and discharge from the cylinder 1, a feed pipe 21 is arranged at the top of the cylinder 1, and a discharge pipe 22 is arranged at the bottom of the cylinder 1. The material enters through the feed pipe 21 and discharges through the discharge pipe 22.
[0041] In order to facilitate the cleaning of the collected dust, a dust discharge pipe (not marked in the figure) is arranged at the bottom of the hollow shell 7. The dust and impurities are discharged through the dust discharge pipe.
[0042] The working principle of this utility model is as follows: First, the material enters the first conical shell 2 inside the cylinder body 1. Then, the rotating assembly drives the conical crushing cone 5 to rotate, so that the material is frictionally extruded against the inner wall of the first conical shell 2 for crushing. During the crushing process, dust will be generated inside the cylinder body 1. At this time, the air guiding assembly provides power to make the dust suction pipe 9 suck the dust and impurities inside the cylinder body 1. The sucked impurities enter the inside of the hollow shell 7, and then pass through the filtration of the filter plate 8, so that the clean air is discharged through the protective shell 10, while the impurities stay inside the hollow shell 7 waiting to be cleaned. At the same time, there will be some impurities that are difficult to adsorb remaining on the crushed impurities. If these impurities are not cleaned, the external dust will fly due to gravity when being discharged. Therefore, when the crushed material moves to the cylindrical shell 3 by gravity, the rotating assembly drives the first impurity cleaning assembly to rotate, so as to clean the impurities on the moving material. Then the crushed material enters the second conical shell 4, and the rotating assembly drives the second impurity removal assembly to clean the impurities on the moving material again. During the cleaning process, the impurity dust is led out and collected through the air guiding assembly. This device can not only remove dust from the crushed material, but also clean some stubborn impurities, improving the dust removal effect.
[0043] The above are only the preferred embodiments of this utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
