Description

Technical Field

[0002] The horizontal scraper discharge centrifuge is a centrifuge that operates continuously and intermittently. Some horizontal scraper discharge centrifuges are difficult to discharge the surface of the object to be scraped.

[0003] In the existing technology, firstly, the position of the scraper of some devices may not be accurately controlled, resulting in poor centrifugal separation effect or increased friction between the scraper and the inner wall of the centrifuge, affecting the life of the equipment. The scraper position needs to be adjusted manually, which increases the difficulty and time of operation and reduces production efficiency. Improper scraper position may cause unstable equipment operation and increase operating risks. Secondly, some devices may be damaged when the rated load is exceeded, affecting production progress and equipment life. The lack of overload protection may cause equipment damage, increase maintenance costs and downtime. Operators may overload the equipment without realizing it, increasing the risk of safety accidents. Finally, some devices cannot adjust the response of the equipment according to different materials and working conditions, reducing the adaptability and flexibility of the equipment, which may cause the overload protection mechanism to be insensitive or unreliable, affecting the normal operation of the equipment, and adjusting the overload protection setting becomes more difficult, increasing the complexity and time of maintenance.

[0030] In this embodiment, the object to be scraped is positioned at this time. First, the support seat 3 is installed on the top end surface of the operating platform 1, the rotating shaft 4 is installed on the support seat 3, and the scraper 5 is arranged on the rotating shaft 4. At this time, the thrust of the electric push rod 6 is used to cooperate with the pressure wheel 8 to press the object to be scraped on the rotating shaft 4, so that the scraper 5 is accurately positioned on the rotating shaft 4 to ensure that the scraper 5 can effectively scrape the surface material of the object to be scraped. When the rotating shaft 4 is running, overload is likely to occur between the drive assembly 19 and the rotating shaft 4. At this time, the anti-overload rod 11 is movably extended into the interior of the anti-overload tube 9, and the anti-overload groove 10 is arranged on the side of the anti-overload rod 11. When the centrifuge is overloaded, the anti-overload mechanism is started, and in cooperation with the anti-overload spring 17, the horizontal push rod 12 pushes the slope block 13 to move along the motion groove 14, forcing the anti-overload rod 11 to extend from the anti-overload groove 10, thereby preventing the centrifuge from continuing to drive the rotating shaft 4 to work and preventing equipment damage.

[0031] The spring adjustment mechanism includes a motion ball 15, a push block 16, an anti-overload spring 17 and an adjustment bolt 18. The push block 16 is movably and directionally arranged inside the motion groove 14. The anti-overload spring 17 is arranged inside the motion groove 14. One end of the push block 16 is matched with the anti-overload spring 17. The inner wall of one end of the motion groove 14 is matched with the adjustment bolt 18 in a threaded arrangement, and one end of the adjustment bolt 18 can be contacted and connected with the anti-overload spring 17.

[0032] In this embodiment, the push block 16 is movably and orientably arranged inside the motion groove 14, and the anti-overload spring 17 is arranged inside the motion groove 14. The anti-overload spring 17 can use the push block 16 to push the horizontal push rod 12 into the anti-overload groove 10. When the centrifugal force is greater than the preload force of the spring, the anti-overload mechanism will be activated, and the preload force of the anti-overload spring 17 can be adjusted by rotating the adjustment bolt 18, thereby affecting the position of the push block 16 and the slope block 13, and then adjusting the working point of the anti-overload mechanism.

[0033] See also Figure 1-5As a supplementary implementation of the auxiliary positioning mechanism, the anti-overload mechanism and the spring adjustment mechanism for a horizontal scraper unloading centrifuge: a driving assembly 19 is provided on the top end face of the operating platform 1, a driven wheel 20 is provided at one end of the rotating shaft 4, and a belt 21 is connected between the driving assembly 19 and the driven wheel 20, a torque adjustment groove 22 is provided on the driven wheel 20, and the belt 21 can be respectively arranged in different torque adjustment grooves 22, an axis groove 23 is opened at one end of the anti-overload tube 9, and the rotating shaft 4 on the side of the driven wheel 20 is cooperatively installed in the axis groove 23, a connecting plate 24 is installed at one end of the anti-overload rod 11, and the connecting plate 24 is cooperatively connected with the rotating shaft 4 at the end of the scraper 5, an auxiliary shaft 25 is provided in parallel on the side of the rotating shaft 4, and the auxiliary shaft 25 is connected to the top end face of the operating platform 1 through the support seat 3, and multiple groups of scrapers 5 are arranged on the auxiliary shaft 25, the operating box 2 is cooperatively installed on the top end face of the operating platform 1, and the bottom end face of the operating platform 1 is connected with a support leg 26.

[0034] More specifically, a power source for the centrifuge is provided, and power is transmitted through the belt 21 to realize the rotation of the scraper 5. The torque adjustment groove 22 allows the torque transmitted by the belt 21 to be adjusted to meet the separation requirements of different materials. An additional scraper 5 is provided to increase the material processing capacity and improve production efficiency. An operating interface and stable support are provided to facilitate operation and maintenance.

[0035] In summary, when the overall equipment is in use or running: when the auxiliary positioning mechanism is required, the object to be scraped is positioned, first the support seat 3 is installed on the top end face of the operating platform 1, the rotating shaft 4 is installed on the support seat 3, and the scraper 5 is set on the rotating shaft 4. At this time, the thrust of the electric push rod 6 is used, and the pressure wheel 8 is cooperated to press the object to be scraped onto the rotating shaft 4, so that the scraper 5 is accurately positioned on the rotating shaft 4 to ensure that the scraper 5 can effectively scrape the surface material of the object to be scraped.

[0036] When the overload protection mechanism needs to be operated, when the shaft 4 is running, an overload situation is likely to occur between the drive assembly 19 and the shaft 4. At this time, the overload protection rod 11 movably extends into the interior of the overload protection tube 9, and the overload protection groove 10 is arranged on the side of the overload protection rod 11. When the centrifuge is overloaded, the overload protection mechanism is activated, and in cooperation with the overload protection spring 17, the push rod 12 pushes the slope block 13 to move along the motion groove 14, forcing the overload protection rod 11 to extend from the overload protection groove 10, thereby preventing the centrifuge from continuing to drive the shaft 4 to work and preventing equipment damage.

[0037] When the spring adjustment mechanism needs to be operated, the push block 16 is movably and directionally arranged inside the motion groove 14, and the anti-overload spring 17 is arranged inside the motion groove 14. The anti-overload spring 17 can use the push block 16 to push the horizontal push rod 12 into the anti-overload groove 10. When the centrifugal force is greater than the preload force of the spring, the anti-overload mechanism will be activated. By rotating the adjustment bolt 18, the preload force of the anti-overload spring 17 can be adjusted, thereby affecting the position of the push block 16 and the slope block 13, and then adjusting the working point of the anti-overload mechanism.
