DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-5The utility model provides a technical solution: a centrifuge that is easy to clean, comprising: a bottom bracket 1, a shell 2 with a hollow interior and an upper opening connected to the upper end of the bottom bracket 1, a rotating motor 3 connected to the lower end of the shell 2, an internal centrifuge drum 4 rotatably connected to the lower end of the shell 2, an upper output end of the rotating motor 3 passes through the lower end of the shell 2 and is fixedly connected to the lower end of the centrifuge drum 4, a limited boss 5 is arranged at the lower end of the upper opening of the shell 2, the outer side of the limited boss 5 is connected to the inner side of the upper opening of the centrifuge drum 4 through a bearing, an annular drainage groove 6 is opened at the lower end of the shell 2, a drain pipe 7 is connected to the left side of the lower end of the shell 2, the drain pipe 7 is communicated with the drainage groove 6, an end cover 8 is arranged at the upper end of the shell 2, and the end cover 8 is connected to the shell 1 are connected by bolts, an electric telescopic rod 9 is connected to the left side of the upper end of the end cover 8, the lower telescopic end of the electric telescopic rod 9 extends to the lower end of the end cover 8, the lower end of the telescopic end of the electric telescopic rod 9 is connected to a steering gear 10, the lower left end of the steering gear 10 is connected to a connecting support rod 11, the left end of the connecting support rod 11 is connected to a scraper 12 by bolts, an input pipe 13 is connected to the middle of the end cover 8, the lower end of the input pipe 13 is connected to a hollow shaft motor 14, the lower end of the hollow shaft motor 14 is connected to a spreader 15, a high-pressure water spraying pipe 16 is connected to the inside of the right side of the end cover 8, a mounting pipe 17 is connected to the middle of the lower end of the centrifuge drum 4, a receiving plate 18 is sleeved on the outside of the mounting pipe 17, and a mounting bolt 19 is provided on the upper end of the mounting pipe 17.
[0022] When in use, connect the input pipe 13 with the injection pipe, the solid-liquid mixture will flow into the inside of the spreader 15 through the input pipe 13, and the hollow shaft motor 14 will drive the spreader 15 to rotate, and the solid-liquid mixture will be evenly thrown on the inner wall of the centrifuge drum 4. The rotating motor 3 connected to the lower end of the outer shell 2 will drive the centrifuge drum 4 to rotate, and the liquid will be thrown out through the centrifuge drum 4. Some solid impurities will be left on the inner wall of the drum 4, and these liquids will flow down through the inner wall of the outer shell 2, flow into the inside of the drainage trough 6, and then be discharged through the drain pipe 7. When cleaning is needed, connect the high-pressure water spray pipe 16 to the water pipe, reduce the speed of the rotating motor 3, and control the steering gear 10 to rotate ninety degrees to let the connection The support rod 11 and the scraper 12 rotate, and the scraper 12 will be close to the inner wall of the centrifuge drum 4, and at the same time, the solids and impurities on the inner wall of the centrifuge drum 4 will be cleaned. After completing this circle of cleaning, the electric telescopic rod 9 is started to push the scraper 12 downward to clean the lower layer of the inner wall of the centrifuge drum 4. The above steps are repeated until the bottom of the inner wall of the centrifuge drum 4 is reached, and these solid impurities will fall into the inside of the receiving plate 18. The water inside the high-pressure water spraying pipe 16 will be sprayed through the high-pressure nozzle to clean the impurities in some gaps and apertures of the centrifuge drum 4. After the cleaning is completed, the mounting bolts 19 are twisted out of the mounting pipe 17, and then the receiving plate 18 is taken out for cleaning to complete the cleaning.
[0023] like Figure 1-5 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the scraper 12 and the axis of the telescopic end of the electric telescopic rod 9 form an oblique angle of forty-five degrees.
[0024] It can be seen from the analysis of the above structure that the stress on the scraper 12 as a whole can be reduced, while preventing the debris scraped off by the scraper 12 from flying away.
[0025] like Figure 1-5 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the left arc of the scraper 12 is tangent to the inner side of the centrifuge drum 4.
[0026] Analysis of the above structure shows that the left curvature of the scraper 12 is tangent to the inner side of the centrifuge drum 4, which increases the contact area between the scraper 12 and the impurities and reduces the stress of the scraper 12 when scraping the impurities on the inner wall.
[0027] like Figure 1-4 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the drainage groove 6 is inclined from right to left, and the inclination angle of the drainage groove 6 is three to five degrees.
[0028] From the analysis of the above structure, it can be known that when the water thrown out falls on the inner wall of the outer shell 2, the water will flow along the inner wall to the inside of the drainage groove 6, and then flow to the inside of the drain pipe 7 along an inclined angle to be discharged.
[0029] like Figure 1-4 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, an observation window 21 is provided inside the left side of the end cover 8 and located on the upper end of the scraper 12, and the observation window 21 is sealed and connected to the end cover 8.
[0030] From the analysis of the above structure, it can be known that when performing internal cleaning, the working state of the scraper 12 can be observed through the observation window 21.
[0031] like Figure 1-4 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the lower surface of the mounting bolt 19 and the upper surface of the middle boss of the receiving plate 18 are both connected with anti-slip rubber strips.
[0032] From the analysis of the above structure, it can be known that when the mounting bolts 19 are locked, the middle boss of the receiving plate 18 and the anti-slip rubber strip on the lower surface of the mounting bolts 19 will stick to each other, increasing the resistance between the receiving plate 18 and the mounting bolts 19, and preventing the receiving plate 18 from stopping in the middle when the centrifuge drum 4 rotates, causing friction between the centrifuge drum 4 and the receiving plate 18.
[0033] like Figure 1-4 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, a chamfer is provided around the opening of the upper end of the inner side of the receiving plate 18.
[0034] From the analysis of the above structure, it can be known that when some debris scraped from the inner wall of the centrifuge drum 4 falls to the edge of the receiving plate 18, it will slide into the inside of the receiving plate 18 through the chamfered corners around the opening of the upper end of the inner side of the receiving plate 18.
