[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0026] like Figure 1-Figure 5 As shown, a nitric oxide donor purification device includes a reactor tank body 1, an upper cover 2 is bolted to the top of the reactor tank body 1, a discharge port 3 is provided at the bottom of the reactor tank body 1, and a detachable sleeve tank 4 is provided at the bottom of the reactor tank body 1. A closed heating cavity is formed between the sleeve tank 4 and the outer wall of the reactor tank body 1. A circular hole with an inner diameter larger than the outer diameter of the discharge port 3 is provided at the bottom of the sleeve tank 4. The discharge port 3 passes through the interior of the circular hole, and the edge of the circular hole is folded upward to form a convex ring 17.

[0027] A mounting ring plate 6 is fixed to the outer wall of the reactor tank body 1 and located above the sleeve tank 4. The outer wall of the mounting ring plate 6 is bent downward 90 degrees along the circumferential direction to form a flange. A plurality of guide rods 7 are provided through the top of the mounting ring plate 6. The outer wall of the mounting ring plate 6 is provided with guide holes slidably connected to the guide rods 7. A fixing ring 8 sleeved on the reactor tank body 1 is fixed between the tops of the plurality of guide rods 7. A connecting rod 19 is fixed to the top of the fixing ring 8. A hydraulic cylinder 18 connected to the connecting rod 19 is fixed to the top of the reactor tank body 1.

[0028] A fixed block 9 is fixed to the bottom end of the guide rod 7, and a slide groove 10 is provided at the bottom of the fixed block 9. A slider 11 is slidably installed inside the slide groove 10. An isosceles trapezoidal block 13 is fixed to the bottom of the slider 11 and located below the fixed block 9. An extrusion slope 15 that is slidably connected to the isosceles trapezoidal block 13 is provided on one side of the flange. A snap ring 14 that cooperates with the isosceles trapezoidal block 13 is fixed to the outer wall of the sleeve tank 4, and the cross-section of the snap ring 14 is trapezoidal.

[0029] According to the above structure, the hydraulic cylinder 18 is started, and the hydraulic cylinder 18 drives the fixing ring 8 to move through the connecting rod 19, and the fixing ring 8 drives the fixing block 9 to move through the guide rod 7, and the fixing block 9 drives the isosceles trapezoidal block 13 to move downward through the slider 11, and the extrusion slope 15 cancels the extrusion of the isosceles trapezoidal block 13. When the sleeve tank 4 is removed, the clamping ring 14 squeezes the isosceles trapezoidal block 13 to move smoothly to one side, and the sleeve tank 4 can be easily removed, thereby facilitating the cleaning of the scale on the reactor tank body 1 and the sleeve tank 4. After the cleaning is completed, the sleeve tank 4 is put on the bottom of the reactor tank body 1, so that the clamping ring 14 on the sleeve tank 4 is inserted above the isosceles trapezoidal block 13, and the elastic force of the spring 12 , push the slider 11 to move to one side, and drive the isosceles trapezoidal block 13 to move to one side, to achieve the preliminary fixation of the sleeve tank 4. After fixation, there is no need to manually hold the sleeve tank 4 to continue the subsequent fixation, which is more labor-saving and convenient. Then start the hydraulic cylinder 18, and the hydraulic cylinder 18 drives the fixing ring 8 to move upward through the connecting rod 19. The fixing ring 8 drives the fixing block 9 to move upward through the guide rod 7, and the fixing block 9 drives the isosceles trapezoidal block 13 to move upward. When the isosceles trapezoidal block 13 moves upward, it will be squeezed by the extrusion inclined surface 15, so that the isosceles trapezoidal block 13 moves to the side of the snap ring 14, and slides with the snap ring 14, so that the sleeve tank 4 can be squeezed when it moves upward, and the stable fixation of the sleeve tank 4 is completed.

[0030] like Figure 6 As shown, the outer wall of the reactor tank body 1 is provided with a mounting plate 20, and the outer wall of the mounting plate 20 is provided with a mounting hole that is slidably connected to the connecting rod 19. The outer wall of the mounting plate 20 is screwed with a big head bolt 21, and one end of the big head bolt 21 extends into the mounting hole and abuts against the connecting rod 19.

[0031] According to the above structure, when the big head bolt 21 is against the connecting rod 19, the guide rod 7 can be fixed by the fixing ring 8, which can effectively prevent the hydraulic cylinder 18 from failing and affecting the stable fixation of the sleeve tank 4. When the big head bolt 21 is disengaged from the connecting rod 19, the hydraulic cylinder 18 can drive the isosceles trapezoidal block 13 at the bottom of the guide rod 7 to move up and down, thereby facilitating the disassembly of the sleeve tank 4.

[0032] like Figure 5 As shown, a spring 12 fixed to the inner side of the sliding groove 10 is fixed on one side of the slider 11 .

[0033] According to the above structure, when the isosceles trapezoidal block 13 is in its initial state, the elastic force of the spring 12 pushes the isosceles trapezoidal block 13 toward the side of the retaining ring 14, so that the isosceles trapezoidal block 13 can clamp the retaining ring 14 on the sleeve tank 4, thereby preliminarily fixing the sleeve tank 4.

[0034] like Figure 1 、 Figure 2 and Figure 4 As shown, the outer wall of the jacket tank 4 is provided with a heat source inlet 5, which facilitates the external hot water to enter the heating cavity and heat the reactor tank body 1. The outer wall of the jacket tank 4 is provided with a drain port below the heat source inlet 5 to facilitate the discharge of the residual liquid in the heating cavity, thereby increasing the practicality of the equipment.

[0035] like Figure 3-Figure 5 As shown, a second sealing ring 22 cooperating with the convex ring 17 is fixed to the bottom of the reactor tank body 1, and a first sealing ring 16 is fixed to the top of the sleeve tank 4. The arrangement of the second sealing ring 22 and the second sealing ring 22 improve the sealing performance of the connection between the reactor tank body 1 and the sleeve tank 4, thereby increasing the normal use of the equipment.

[0036] like Figure 3 As shown, a plurality of heat-conducting protrusions 23 are fixed on the outer wall of the reactor tank body 1 and located inside the jacket tank 4. When heating hot water in the heating cavity, the arrangement of the heat-conducting protrusions 23 increases the contact area between the hot water and the outer wall of the reactor tank body 1, so that the heat can be quickly transferred to the interior of the reactor tank body 1.

[0037] The working principle of the present invention is as follows: when the big head bolt 21 is loosened and the big head bolt 21 is disengaged from the connecting rod 19, the hydraulic cylinder 18 is started, and the hydraulic cylinder 18 drives the fixing ring 8 to move through the connecting rod 19, and the fixing ring 8 drives the fixing block 9 to move through the guide rod 7, and the fixing block 9 drives the isosceles trapezoidal block 13 to move downward through the slider 11, and the extrusion inclined surface 15 cancels the extrusion of the isosceles trapezoidal block 13. When the sleeve tank 4 is removed, the clamping ring 14 squeezes the isosceles trapezoidal block 13 and can move smoothly to one side, so that the sleeve tank 4 can be easily removed, thereby facilitating the cleaning of the reactor tank body 1 and the scale on the sleeve tank 4. After the cleaning is completed, the sleeve tank 4 is sleeved on the bottom of the reactor tank body 1, so that the clamping ring 14 on the sleeve tank 4 is inserted above the isosceles trapezoidal block 13, and through the elastic force of the spring 12, Push the slider 11 to move to one side, and drive the isosceles trapezoidal block 13 to move to one side, so as to achieve the preliminary fixation of the sleeve tank 4. After fixation, there is no need to manually hold the sleeve tank 4 to continue the subsequent fixation, which is more labor-saving and convenient. Then start the hydraulic cylinder 18, and the hydraulic cylinder 18 drives the fixing ring 8 to move upward through the connecting rod 19. The fixing ring 8 drives the fixing block 9 to move upward through the guide rod 7, and the fixing block 9 drives the isosceles trapezoidal block 13 to move upward. When the isosceles trapezoidal block 13 moves upward, it will be squeezed by the extrusion inclined surface 15, so that the isosceles trapezoidal block 13 moves to the side of the retaining ring 14 and slides with the retaining ring 14, so that the sleeve tank 4 can be squeezed when it moves up, and the stable fixation of the sleeve tank 4 is completed. Finally, tighten the big head bolt 21 to resist the connecting rod 19 to improve the stability of the fixation of the sleeve tank 4.

[0038] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
