[0002] The dust entering the centrifugal sand making machine will affect the normal operation of the sand making machine. The dust entering mainly comes from impurities such as soil and dust in the raw materials. After these impurities enter the centrifugal sand making machine, they will increase the wear and failure rate of the sand making machine and shorten the service life of the equipment, especially the rotor shaft position. Since the rotor rotates at high speed, the wear caused by the dust entering the shaft position is very large, which affects the service life of the rotor. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Utility Model Content

[0033] The self-cleaning rotor of the sand making machine of the utility model is described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0034] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0035] See also Figure 1-Figure 4The self-cleaning rotor of the sand making machine of this embodiment can generate wind pressure with the rotation of the rotor, form an airflow barrier, blow away impurities such as soil and dust from the raw materials, greatly reduce the amount of dust entering the shaft position, thereby reducing the wear and failure rate of the sand making machine rotor and extending the service life of the equipment. In this embodiment, it mainly includes an upper plate 1, a lower plate 2, and a wall plate 3. A feed port 5 that runs through the upper and lower parts is opened in the middle of the upper plate 1, and the feed port 5 is used to feed the inside of the rotor. The lower plate 2 is connected to the outside world through a rotating core 6 set in the middle of its bottom end, and the rotation of the rotor is realized through the rotating core 6. The upper plate 1 and the lower plate 2 are connected by multiple vertically arranged wall panels 3. At least three wall panels 3 are arranged evenly distributed around the circumference. When the rotor rotates, the balance of the rotor during rotation is achieved through the multiple wall panels 3 evenly distributed around the circumference to reduce friction. The wall panel 3 is an arc-shaped structure. One end of the wall panel 3 is inclined to the central axis position of the rotor. The materials are accumulated by the arc-shaped wall plate 3 with one end inclined toward the central axis of the rotor, so that the subsequent materials are thrown out from the rotor in a certain trajectory.

[0036] For throwing and crushing materials. Figure 1-Figure 4 , in this embodiment, it also includes a flow channel assembly 4, and the flow channel assembly 4 is respectively arranged at the opposite ends of the upper plate 1 and the lower plate 2. The flow channel assembly 4 includes an upper flow channel plate 41, a lower flow channel plate 42, and a material baffle plate 43. The upper flow channel plate 41 is fixedly arranged on the inner side of the upper plate 1 at the end of the wall panel 3, and the lower flow channel plate 42 is fixedly arranged on the inner side of the lower plate 2 at the end of the wall panel 3. The upper flow channel plate 41 and the lower flow channel plate 42 are relatively arranged and have the same structure. The upper flow channel plate 41 and the lower flow channel plate 42 are common prior arts and are not described here. The upper flow channel plate 41 and the lower flow channel plate 42 can ensure that the material is thrown out at an appropriate speed and direction. In addition, the upper flow channel plate 41 and the lower flow channel plate 42 also play a role in protecting the rotor of the sand making machine, thereby extending the service life of the equipment. The baffle plate 43 is vertically fixedly arranged on the inner side of the end of the wall panel 3 inclined toward the central axis of the rotor, and the side of the baffle plate 43 faces the central axis of the rotor. The baffle plate 43 cooperates with the arc-shaped wall panel 3 to achieve material accumulation.

[0037] The flow channel assembly 4 also includes a crushing assembly 44, and the crushing assembly 44 is fixedly arranged on the wall panel 3. The crushing assembly 44 includes a knife baffle 441, an impact block 442 and a knife plate 443. The knife baffle 441 is vertically arranged on the outer side of the end of the wall panel 3 inclined toward the central axis of the rotor, and the side of the knife baffle 441 is arranged opposite to the central axis of the rotor. The impact block 442 is vertically fixedly arranged on the knife baffle 441. The knife plate 443 is vertically fixedly arranged at the other end of the wall panel 3. The crushing assembly 44 can throw and crush materials, and can also protect the inner wall of the rotor from being damaged by the materials.

[0038] To reduce the amount of dust entering. Figure 3 and Figure 4 In this embodiment, a plurality of scraper blocks 7 for cleaning the rotor are fixedly provided at the bottom end of the lower plate 2 outside the rotating core 6. There are at least three scraper blocks 7 evenly distributed around the circumference. If there are two or less, imbalance is likely to occur, and if there are more than three, it is likely to affect wind resistance. The scraper block 7 is a rectangular structure. Dynamic balance is achieved by using a plurality of scraper blocks 7 evenly distributed around the circumference to avoid equipment wear caused by imbalance. When the rotor rotates, wind pressure can be generated with the rotation of the rotor to form an airflow barrier, which can blow away impurities such as soil and dust from the raw materials, greatly reducing the amount of dust entering the rotating shaft, thereby reducing the wear and failure rate of the sand making machine rotor and extending the service life of the equipment.

[0039] The method of using the self-cleaning rotor of the sand making machine of the utility model is as follows: first, the rotor is placed inside the sand making machine through the rotating core 6. During sand making, the rotor rotates through the rotating core 6, and the material enters the inside of the rotor from the feed port 5, and the dynamic balance of the rotor during rotation is achieved through the wall panel 3. The material accumulation is achieved by cooperating with the wall panel 3 with an arc structure through the material baffle plate 43, and the inner wall of the rotor and the impact block 442 are protected to prevent the material from directly impacting the inner wall of the rotor and causing damage to the rotor. During the rotation of the rotor, under the action of centrifugal force, the material entering the inside of the rotor passes through the upper flow channel plate 41 and the lower flow channel plate 42 to ensure that the material is thrown out at an appropriate speed and direction. In this process, the material is thrown out and crushed by the knife baffle plate 441, the impact block 442 and the knife plate 443, and the inner wall of the rotor can be protected from damage by the material.

[0040] When making sand, the scraper block 7 rotates with the rotor, generating wind pressure and forming an airflow barrier, thereby blowing away impurities such as soil and dust from the raw materials, greatly reducing the amount of dust entering the shaft position, reducing the wear and failure rate of the sand making machine rotor and extending the service life of the equipment.

[0041] Embodiment 2: The same points as Embodiment 1 are not described in detail, and the difference is that:

[0042] In order to reduce the dust entering the device shaft position. In this embodiment, see Figure 3 and Figure 4 At least three scraper blocks 7 are provided and are evenly distributed around the circumference. The scraper blocks 7 are trapezoidal structures that gradually narrow on both sides opposite to the lower plate 2. The scraper blocks 7 with trapezoidal design can form an airflow barrier when the rotor rotates to blow away impurities such as soil and dust from the raw materials. The amount of dust entering the shaft position is greatly reduced, thereby reducing the wear and failure rate of the sand making machine and extending the service life of the equipment. It can also reduce the damage caused by the material to the scraper blocks 7 when the rotor rotates, thereby extending the service life of the scraper blocks 7.

[0043] The present invention also discloses a centrifugal impact sand making machine, comprising a sand making machine housing and a sand making machine rotor, wherein the sand making machine rotor is rotatably arranged inside the sand making machine housing. The sand making machine rotor is the above-mentioned sand making machine self-cleaning rotor.
