[0030] Embodiment 1

[0031] Reference Figures 1-6 For the first embodiment of the present application, the embodiment provides a high-speed mixed bed bottom resin flushing device, specifically comprising, a flushing mechanism 100, which comprises a flushing pipe assembly 101, and a nozzle assembly 102 arranged in the flushing pipe assembly 101; a protective reinforcement mechanism 200, which comprises a protective sleeve assembly 201 arranged outside the flushing pipe assembly 101, and an adjusting sleeve assembly 202 fixed on the top of the flushing pipe assembly 101, the adjusting sleeve assembly 202 being arranged outside the protective sleeve assembly 201.

[0032] Further, the flushing pipe assembly 101 comprises a main pipe 101a, a reinforcing pipe 101b fixed on the upper part of the main pipe 101a, a flow-through cover 101c fixed on the top end of the reinforcing pipe 101b, and reinforcing piers 101d fixed on the inner wall of the reinforcing pipe 101b; the wall thickness of the reinforcing pipe 101b is thicker than that of the main pipe 101a.

[0033] Further, the protective sleeve assembly 201 comprises a protective sleeve 201a arranged outside the reinforcing pipe 101b and the main pipe 101a, a closing cover 201b fixed on the top of the protective sleeve 201a, and a second spring 201c contacting the inner wall of the bottom of the reinforcing pipe 101b and the bottom of the protective sleeve 201a respectively.

[0034] Preferably, the adjusting sleeve assembly 202 comprises a pressure pipe 202a fixed on the upper part of the flow-through cover 101c, a pressure column 202b slidingly arranged in the pressure pipe 202a, an adjusting cover 202c fixed on the top of the pressure column 202b, and an adjusting sleeve 202d fixed on the lower part of the adjusting cover 202c.

[0035] In the embodiment, the high-speed mixed bed bottom resin flushing device can automatically spray the high-pressure water column through the nozzle assembly 102 to clean the residual resin at the bottom of the mixed bed under the condition that the water pressure flowing into the flushing pipe assembly 101 is sufficient, by the cooperation of the nozzle assembly 102, the flushing pipe assembly 101 and the protective sleeve assembly 201; and the nozzle assembly 102 can remain stable when the water pressure is unstable, by the cooperation of the above-mentioned assemblies and the adjusting sleeve assembly 202.

[0036] Embodiment 2

[0037] With reference to Figures 1-9 For the second embodiment of the application, the embodiment is based on the previous embodiment.

[0038] Specifically, the first spray hole W-1 is formed in the side wall of the reinforced pipe 101b and communicates with the inside of the reinforced pipe 101b, and the first spray hole W-1 is located above the reinforced bump 101d; a plurality of flow-through holes W-2 are formed in the flow-through cover 101c.

[0039] Further, the nozzle assembly 102 includes a nozzle 102a slidingly arranged in the first spray hole W-1, a spring plate 102b fixed to the outer ring surface of the nozzle 102a, and a first spring 102c having two ends fixed to the spring plate 102b and the reinforced bump 101d, respectively.

[0040] It should be noted that under the elastic force of the first spring 102c, the nozzle 102a can maintain the state that the end portion is in the first spray hole W-1 and flush with the outer wall of the reinforced pipe 101b.

[0041] Further, a recessed clamping groove W-3 is formed in the outer side wall of the nozzle 102a, a spray cavity W-4 is formed in the nozzle 102a and communicates with the inside of the reinforced pipe 101b, and the spray cavity W-4 and the clamping groove W-3 do not communicate with each other; an expansion hole W-5 is formed in the end portion of the nozzle 102a close to the first spray hole W-1, and the edges of the end portion of the nozzle 102a close to the first spray hole W-1 are rounded; the cross-sectional area of the nozzle 102a minus the cross-sectional area of the expansion hole W-5 is greater than the area of the limiting disc 202e.

[0042] It should be noted that the clamping groove W-3 is a circular arc groove, and the radius of the circular arc groove W-3 is the same as the radius of the adjusting sleeve 202d, which is conducive to the clamping of the adjusting sleeve 202d in the clamping groove W-3; preferably, the expansion hole W-5 can be a sector hole, which can increase the spraying range when the water liquid is sprayed from the expansion hole W-5 to the outside, so as to increase the flushing area of the high-speed mixed bed bottom resin.

[0043] Furthermore, a second spray hole W-6 is provided on the outer wall of the protective cover 201a, and the second spray hole W-6 is located below the first spray hole W-1; a sealing hole W-7 is provided on the sealing cover 201b, and the sealing hole W-7 is located in the middle of the sealing cover 201b.

[0044] It should be noted that the diameter of the second nozzle W-6 is the same as that of the first nozzle W-1, which allows the nozzle 102a to slide stably axially into the second nozzle W-6.

[0045] Furthermore, a pressure hole W-8 is provided in the pressure tube 202a, and a first limiting ring 202a-1 and a second limiting ring 202a-2 are fixed from bottom to top in the inner wall of the pressure hole W-8; a limiting disk 202e is also fixed at the bottom of the pressure column 202b, and the limiting disk 202e is slidably disposed between the first limiting ring 202a-1 and the second limiting ring 202a-2; the diameter of the limiting disk 202e is smaller than the inner diameter of the first limiting ring 202a-1 and the second limiting ring 202a-2, which can limit the sliding range of the limiting disk 202e.

[0046] Preferably, the adjusting sleeve 202d includes a main sleeve 202d-1, a connecting post 202d-2 fixed to the lower part of the main sleeve 202d-1, and a retaining ring 202d-3 fixed to the lower part of the connecting post 202d-2. The length of the connecting post 202d-2 is greater than the diameter of the second nozzle W-6. The bottom plane of the main sleeve 202d-1, the side wall plane of the connecting post 202d-2, and the upper plane of the retaining ring 202d-3 form a through hole W-9, which is located below the second nozzle W-6.

[0047] In this embodiment, when resin residue remains at the bottom of the high-speed mixed bed and needs to be cleaned, the operator needs to open the valve connected to the resin flushing device at the bottom of the high-speed mixed bed, so that water flows into the flushing pipe assembly 101. After the water pressure inside the flushing pipe assembly 101 increases, the water will flow into the pressure pipe 202a and give the limiting plate 202e an upward force. This will cause the limiting plate 202e to drive the adjusting sleeve 202d to slide upward as a whole, so that the through hole W-9 slides to the point where the retaining ring 202d-3 is slightly higher than the lowest point of the side wall of the first spray hole W-1.

[0048] It should be noted that after the water pressure inside the flushing pipe assembly 101 further increases, since the reinforcing pipe 101b and the protective sleeve 201a are interconnected through the flow hole W-2, the water pressure inside the flushing pipe assembly 101 will act on the sealing cover 201b, causing the protective sleeve 201a to rise against the pressure of the second spring 201c. This will cause the second nozzle W-6 to align with the first nozzle W-1. Without the restriction of the inner wall of the protective sleeve 201a, the nozzle 102a will be forced out to the outside of the second nozzle W-6 under the water pressure inside the flushing pipe assembly 101, and spray water through the diffuser hole W-5 to flush the residual resin at the bottom of the high-speed mixed bed.

[0049] It should be noted that when the limiting disc 202e drives the adjusting sleeve 202d to slide, and the through hole W-9 slides to a position slightly higher than the lowest position of the sidewall of the first spray hole W-1, when the nozzle 102a is pressed out to the second spray hole W-6, the rounded portion on the nozzle 102a will first press the snap ring 202d-3, so that the snap ring 202d-3 slides downward slightly, and then after the nozzle 102a is completely slid out, the snap ring 202d-3 will be clamped into the clamping groove W-3 under the water pressure at the limiting disc 202e; after that, even if the water pressure inside the flush pipe assembly 101 is unstable, the nozzle 102a can still be kept stable under the limiting of the snap ring 202d-3 to the clamping groove W-3.

[0050] It should be noted that only when the water pressure inside the flush pipe assembly 101 is completely reduced, and the water pressure at the limiting disc 202e can no longer lift the adjusting sleeve 202d, the snap ring 202d-3 can slide out of the clamping groove W-3, so that the nozzle 102a can be reset under the elastic force of the first spring 102c; after the nozzle 102a is slid into the first spray hole W-1 again, the protective sleeve 201a can also be reset under the elastic force of the second spring 201c, and since the inner wall of the main sleeve 202d-1 can block the second spray hole W-6 (as shown in Figure 8 ), after the adjusting sleeve 202d falls, the resin can be prevented from remaining in the adjusting sleeve 202d.

[0051] It should be understood that during the development of any actual implementation, numerous implementation-specific decisions can be made. Such development efforts, while possibly complex and time-consuming, would nevertheless be routine undertaking for those of ordinary skill in the art having the benefit of this disclosure, and would not require undue experimentation to develop.

[0052] It should be noted that the above examples are only used to illustrate the technical solutions of the present application and not to limit it, although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
