Description

TECHNICAL FIELD

[0001] The utility model relates to the field of foundry scouring sand, especially to a scouring sand dewatering spiral classifier. BACKGROUND

[0002] In the field of mineral processing, scouring sand is a common raw material processing process, and the scouring operation aims to remove impurities, soil and other attachments on the surface of sand particles to improve the purity and quality of sand. However, the sand after scouring often contains a large amount of water and needs to be effectively dewatered. At the same time, in order to meet the different industrial application requirements, the sand also needs to be classified and screened to obtain products of different particle sizes. This process is crucial to many industries such as construction, glass manufacturing, and casting.

[0003] In the scouring sand dewatering industry, the scouring sand dewatering and classifying equipment plays a crucial role in the entire production process. In terms of dewatering, it can quickly remove most of the water in the sand, reducing the water content of the sand to a level that meets the requirements of subsequent processing or storage. In terms of classification, through specific structural design and operation mechanism, it can classify sand particles according to their size, ensuring that sand of different particle sizes is effectively separated.

[0004] However, the traditional scouring sand dewatering and classifying equipment often has some problems. Since the dewatering and classifying equipment usually has a fixed structure, it cannot adjust the inclination angle of the equipment flexibly according to the actual production situation. This limitation greatly limits the performance of the equipment. In actual production, the characteristics of scouring sand are complex and diverse. Scouring sand from different sources and processed by different processes has differences in particle size, humidity, and viscosity. The inclination angle of the equipment has a key influence on the transmission speed of the material in the screw machine, the residence time, and the accumulation of the material. Since the inclination angle cannot be flexibly changed, the traditional equipment cannot be adjusted to adapt to different characteristics of scouring sand or different production process requirements, making it difficult to accurately control the dewatering and classification process of the material when processing some special materials or responding to special process requirements. This can lead to incomplete dewatering and inaccurate classification, seriously affecting the universality and adaptability of the equipment and making it difficult to meet the diversified needs of multiple industries for the quality and yield of scouring sand.

[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application. Figure 1 Figure 3 ​​The outer wall of the screw conveyor housing 15 is equipped with a lifting assembly for adjusting the tilt of the screw conveyor. The lifting assembly includes a connector 5, the upper surface of which is fixedly connected to the outer wall of the screw conveyor housing 15. An upper lug 6 is rotatably connected inside the connector 5. When the screw conveyor needs to be tilted upwards, the hydraulic cylinder 11 starts working. A lower lug 10 is fixedly connected to the lower surface of the hydraulic cylinder 11, and a support 9 is rotatably connected inside the lower lug 10. The output end of the hydraulic cylinder 11 is fixedly connected inside the upper lug 6. The output end of the hydraulic cylinder 11 extends outwards, thereby moving the upper lug 6. The movement is further controlled by the rotation of the upper lug 6 and the connector 5. The spiral casing 15 can be driven to rotate upward around the shaft 19, thereby increasing the tilt angle of the spiral and achieving the effect of rising. The outer wall of the spiral casing 15 is provided with the shaft 19, and the outer wall of the shaft 19 is rotatably connected to the inside of the support 9. When it is necessary to adjust the tilt angle of the spiral to make it descend, the working process of the hydraulic cylinder 11 is reversed with the upward operation, thereby reducing the tilt angle of the spiral and achieving the purpose of descending. By controlling the extension and retraction of the output end of the hydraulic cylinder 11, the tilt angle of the spiral casing 15 can be precisely adjusted. According to the flow characteristics of sand and water, the appropriate tilt angle can be adjusted to ensure the efficient and stable operation of the equipment.

[0025] Reference Figure 1 - Figure 3 The coupling 2 connects the drive motor 1 and the reducer 3. By placing the reducer 3 between the universal joint 12 and the screw shaft 21, the integrity and efficiency of the power transmission link can be effectively ensured, thereby providing stable power to the screw shaft 21 for continuous rotation. Furthermore, the coupling 2 ensures precise and stable power transmission. A sealed bearing 20 is provided on one side of the outer wall of the screw shaft 21, providing support and positioning for the screw shaft 21. The groove is made of high-strength, corrosion-resistant steel plate, capable of withstanding the scrubbing sand. To mitigate wear and tear and the corrosive environment of long-term contact with water, the spiral shaft 21 is designed with a thicker core to enhance its stability, wear resistance, and load-bearing capacity. The spiral blades 14 are made of manganese steel with a curved surface and are cleverly fitted with a wear-resistant nylon plate of a certain thickness. When the spiral shaft 21 rotates, it can not only push the sand particles upward to achieve grading, but also improve its service life. The rotating shaft 19 provides a stable support structure for the entire spiral machine. Mounting part 7 and mounting part 8 are fixedly connected to the outer wall of the cylinder 11.

[0027] When it is necessary to adjust the inclination angle of the screw machine to make it rise, the oil cylinder 11 starts to work, the output end of the oil cylinder 11 extends outward, which can drive the upper ear ring 6 to move, and then the upper ear ring 6 and the connecting piece 5 rotate, which can drive the screw machine shell 15 to rotate upward around the rotating shaft 19, so as to increase the inclination angle of the screw machine and achieve the effect of rising, when it is necessary to adjust the inclination angle of the screw machine to make it decline, the working process of the oil cylinder 11 is opposite to that of the rising operation, so as to realize the decrease of the inclination angle of the screw machine and achieve the purpose of decline, by controlling the extension and retraction of the output end of the oil cylinder 11, the inclination angle of the screw machine shell 15 can be accurately adjusted, and the inclination angle can be adjusted to the appropriate angle according to the flow characteristics of the sand and water, so as to ensure the efficient and stable operation of the equipment;

[0028] By setting the speed reducer 3 between the universal shaft 12 and the spiral shaft 21, the integrity and efficiency of the power transmission link can be effectively guaranteed, so that the spiral shaft 21 can obtain stable power to continue rotating, and by setting the shaft coupling 2, the power can be accurately and stably transmitted, the material of the tank is selected from high-strength and corrosion-resistant steel plate, so as to withstand the wear of scouring sand and the corrosion environment of long-term contact with water, the spiral shaft 21 is designed to be thickened to enhance its stability, wear resistance and carrying capacity, the spiral blade 14 is made of manganese steel material in the shape of curved surface, and a certain thickness of wear-resistant nylon plate is also ingeniously installed around it, which can not only push the sand upward to realize classification when the spiral shaft 21 rotates, but also improve the service life.

[0029] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
