Description

Technical Field

[0001] This application relates to the field of horizontal screw centrifuge technology, and more particularly to a self-cleaning device for a horizontal screw centrifuge. Background Technology

[0002] Horizontal screw centrifuges are easy-to-use screw discharge sedimentation centrifuges. When using existing horizontal screw centrifuges, the separated solids tend to adhere to the inner wall of the chamber, so the centrifuge needs to be cleaned frequently. The traditional cleaning method usually involves disassembling the drum and then removing the screw propeller for cleaning, which is a cumbersome operation.

[0003] Patent CN214262368U discloses a horizontal spiral centrifuge that is easy to clean. It uses a closable strip cleaning port on the drum, inserts a cleaning tube into the cleaning port, and uses the water sprayed from the cleaning tube to complete the cleaning work.

[0004] However, the opening and closing of the strip cleaning port in the above-mentioned disclosure requires manual operation, which is cumbersome and has a low degree of automation. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a self-cleaning device for a horizontal screw centrifuge to improve the convenience of opening and closing the water inlet.

[0006] The technical solution of this application is as follows:

[0007] This application provides a self-cleaning device for a horizontal spiral centrifuge, including a centrifuge, a lifting frame, and a cleaning pipe. An opening and closing mechanism is provided in the water inlet of the centrifuge. The opening and closing mechanism includes a pipe that is elastically connected in the water inlet. The outer wall of the pipe is provided with a water outlet groove. The pipe extends into the centrifuge under the push of the cleaning pipe. The water outlet groove connects the centrifuge and the cleaning pipe.

[0008] By adopting the technical solution of this application, an opening and closing mechanism is added inside the water inlet. The movement of the pipe fittings of the opening and closing mechanism inside the water inlet under the push of the cleaning pipe can control the opening and closing of the water inlet, thereby improving the convenience of opening and closing the water inlet.

[0009] In some implementations, the water inlet is configured as a circle arranged radially along the centrifuge.

[0010] In some implementations, a support ring is screwed into the water inlet.

[0011] In some implementations, the inner end of the pipe fitting is closed.

[0012] In some implementations, the external screw of the fitting has a limiting ring, and a spring is provided between the limiting ring and the support ring.

[0013] In some implementations, the spring is fitted onto the outside of the tube.

[0014] In some implementations, the lower end of the fitting has a step that abuts against the support ring.

[0015] In some implementations, the water outlet is arranged on the periphery of the steps.

[0016] In some implementations, the water outlet channels are evenly distributed along the circumference of the steps.

[0017] In some implementations, a sealing ring is fitted onto the step below the water outlet. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0027] In related technologies, horizontal screw centrifuges are easy-to-discharge sedimentation centrifuges. When using existing horizontal screw centrifuges, the separated solids tend to adhere to the inner wall of the chamber, so the centrifuge needs to be cleaned frequently. The traditional cleaning method usually involves disassembling the drum and then removing the screw propeller for cleaning, which is cumbersome.

[0028] Patent CN214262368U discloses a horizontal spiral centrifuge that is easy to clean. It has an openable and closable strip cleaning port 11 (i.e., water inlet) on the drum of the centrifuge 10, and a lifting frame 20 is installed outside the centrifuge 10. At the same time, a cleaning pipe 21 is installed on the lifting frame 20. After the strip cleaning port 11 is opened, the cleaning pipe 21 is inserted into the strip cleaning port 11, and the water sprayed from the cleaning pipe 21 is used to complete the cleaning work. After the cleaning work is completed, the strip cleaning port 11 is closed.

[0029] However, in the above disclosure, both opening and closing of the strip cleaning port 11 require manual operation, and opening and closing are two relatively independent operations, which makes the automatic cleaning operation cumbersome and the degree of automation low.

[0030] In view of this, the purpose of this embodiment is to provide a self-cleaning device for a horizontal screw centrifuge, so as to improve the convenience of opening and closing the water inlet.

[0031] Please see Figures 1-3 In this embodiment, the present application provides a self-cleaning device for a horizontal spiral centrifuge, including a centrifuge 10, a lifting frame 20 and a cleaning pipe 21. An opening and closing mechanism 30 is provided in the water inlet 12 on the centrifuge 10. The opening and closing mechanism 30 includes a pipe 31 elastically connected in the water inlet 12. The outer wall of the pipe 31 is provided with a water outlet groove 34. The pipe 31 extends into the centrifuge 10 under the push of the cleaning pipe 21. The water outlet groove 34 connects the centrifuge 10 and the cleaning pipe 21.

[0032] The technical solution of this embodiment is adopted, and an opening and closing mechanism 30 is added inside the water inlet 12. The pipe 31 of the opening and closing mechanism 30 can control the opening and closing of the water inlet 12 by moving inside the water inlet 12 under the push of the cleaning pipe 21, thereby improving the convenience of opening and closing the water inlet 12.

[0033] In this embodiment, the water inlet 12 is configured as a circle arranged radially along the centrifuge 10, and a support ring 13 is screwed into the water inlet 12. The support ring 13 is coaxially arranged with the water inlet 12 and is located near the lower end of the water inlet 12.

[0034] In this embodiment, the opening and closing mechanism 30 includes a pipe 31, a limiting ring 32, a spring 33, a water outlet 34, a sealing ring 35, and a step 36. The pipe 31 is constructed as a circular tube with an open outer end and a closed inner end. A step 36 with an increased outer diameter is provided at the inner end (lower end) of the pipe 31. The step 36 is constructed as a cylinder coaxially arranged with the pipe 31. The outer diameter of the pipe 31 is equal to the inner diameter of the support ring 13. The pipe 31 is entirely inserted inside the support ring 13. The step 36... The entire structure is arranged below the support ring 13. A water outlet groove 34 is provided on the circumferential surface of the step 36, and the water outlet groove 34 is evenly distributed along the circumference of the step 36. At the same time, a sealing ring 35 is snapped onto the circumferential surface of the step 36. The sealing ring 35 is arranged between the inner wall of the step 36 and the water inlet 12 to form a sealed connection between the inner wall of the step 36 and the water inlet 12. The sealing ring 35 is arranged entirely below the water outlet groove 34, that is, the water outlet groove 34 is arranged between the sealing ring 35 and the support ring 13.

[0035] Additionally, a limiting ring 32 is screwed onto the outer end (i.e., the upper end) of the pipe fitting 31. The limiting ring 32 is arranged above the support ring 13. At the same time, a spring 33 is sleeved on the outside of the pipe fitting 31. The spring 33 is compressed between the limiting ring 32 and the support ring 13. Under the push of the spring 33, the pipe fitting 31 has an upward movement tendency, so that the step 36 abuts against the support ring 13 and the sealing ring 35 fits against the inner wall of the water inlet 12, thereby sealing the water inlet 12.

[0036] It should be noted that when the cleaning pipe 21 pushes the fitting 31 inward, the spring 33 will be further compressed. At the same time, the sealing ring 35 will move out of the water inlet 12 as the fitting 31 moves inward, and the water outlet 34 will extend into the inner cavity of the centrifuge 10. At this time, the water flowing out of the cleaning pipe 21 will flow into the fitting 31 and into the centrifuge 10 through the water outlet 34. That is, the water outlet 34 connects the cleaning pipe 21 and the centrifuge 10, and the water inlet 12 is in the open state.

[0037] After the cleaning pipe 21 is removed from the water inlet 12, the pipe 31 moves upward under the pushing force of the spring 33, and the sealing ring 35 moves back into the water inlet 12. At this time, the water inlet 12 is in the closed state.

[0038] It should be understood that, compared with the existing strip cleaning port 11, the water inlet 12 of this application is equipped with an opening and closing mechanism 30, which can automatically switch the opening and closing state according to whether the cleaning pipe 21 is inserted, making the operation more convenient.

[0039] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
