Description

Technical Field

[0001] The utility model relates to the technical field of spray washing, in particular to a washing spray device applied to a phosphoric acid concentration system. Background Art

[0002] When concentrating phosphoric acid, it is usually necessary to promptly treat the residual concentrated acid and wall scale inside the tank to prevent the residual phosphoric acid from affecting the subsequent concentrated liquid. Therefore, timely treatment of wall scale and residual concentrated acid can effectively protect the concentration equipment.

[0003] Patent No. CN216755928U proposes a high-efficiency spray washing device for desulfurization and denitrification. The utility model includes a first tower body, a second tower body, a third tower body and a connecting structure. The surface of the first tower body is provided with a connecting structure, and the connecting structure includes a first block. The surface of the first block is fixedly connected to the first tower body. The surface of the third tower body is fixedly connected to the second block. The internal thread of the first block is provided with a screw. The top of the screw is rotatably connected to the top plate. The surface of the second block is provided with a connecting groove. The size of the connecting groove is larger than the size of the screw. The surface of the first block is fixedly connected to a telescopic rod. This solves the problem that the tower bodies are connected together by welding, and welding needs to be done around the washing tower, so welding is more troublesome. At the same time, the smoke generated during welding will also cause harm to the staff.

[0004] When in use, the existing device lacks a mechanism for adjusting the flow rate of the fluid inside the spray pipe, and cannot perform targeted treatment according to the thickness of the wall scale remaining on the inner wall of the tank. When the wall scale is too thick, the cleaning liquid with a fixed flow rate and water pressure cannot completely remove the wall scale. When the wall scale is too thin, the fluid flow rate is too fast and it is easy to erode the tank itself.

[0005] Therefore, the present application provides a washing spray device applied to a phosphoric acid concentration system to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0031] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a washing and spraying device for a phosphoric acid concentration system, comprising a phosphoric acid concentration tank body 1, a water pump 2 disposed on the top of the phosphoric acid concentration tank body 1, a phosphate stock solution inlet 3 disposed on the top of the phosphoric acid concentration tank body 1, a shutoff mechanism 4 disposed inside the phosphoric acid concentration tank body 1, a servo motor 5 disposed at the bottom of the phosphoric acid concentration tank body 1, and an adjustment mechanism 6 disposed on one side of the shutoff mechanism 4;

[0032] like Figure 3 、 Figure 4 and Figure 5As shown, the shut-off mechanism 4 includes a knob 401, a first rotating shaft 402, a sealing cover 403, a sealing sleeve 404, a sealing ring 405, a first gear 406, a cross tube 407, a side tube 408 and a second gear 409. The knob 401 is movably connected to the top of the phosphoric acid concentration tank body 1. The bottom of the knob 401 is fixedly connected to the first rotating shaft 402. The sealing cover 403 is fixedly sleeved on one side of the first rotating shaft 402. The sealing sleeve 404 is movably sleeved on the bottom of the sealing cover 403. A sealing ring 405 is provided on one side of the first rotating shaft 402. The bottom of the first rotating shaft 402 is fixedly connected to the first gear 406. The first gear 406 is movably installed inside the cross tube 407. The side tube 408 is fixedly installed on one side of the cross tube 407. One side of the first gear 406 is meshed with the second gear 409.

[0033] The shut-off mechanism 4 also includes a second rotating shaft 410, a valve body 411, a first sealing block 412 and a second sealing block 413. The top of the second gear 409 is fixedly connected to the second rotating shaft 410, the top of the second rotating shaft 410 is fixedly connected to the valve body 411, one side of the valve body 411 is movably connected to the first sealing block 412, and the other side of the valve body 411 is movably connected to the second sealing block 413.

[0034] Three groups of holes with different apertures are opened on one side of the valve body 411. The first sealing block 412 and the second sealing block 413 are both arranged inside the cross tube 407. The first sealing block 412, the second sealing block 413 and the valve body 411 separate the cross tube 407 into two cavities.

[0035] The second gear 409 is movably installed inside the side tube 408. The side tube 408 and the second gear 409 are symmetrically arranged on both sides of the cross tube 407. The sealing ring 405 divides the cross tube 407 into two cavities.

[0036] It should be further explained that when the interior of the phosphoric acid concentration tank body 1 needs to be cleaned, cleaning liquid is pumped into the interior of the cross tube 407 by the water pump 2. Then, by manually pulling the knob 401, the sealing cover 403 is driven to separate from the sealing sleeve 404. At this time, the cleaning liquid can pass through the hole in the sealing sleeve 404 to the side of the valve body 411 and enter the first sprayer 61 and the second sprayer 62 through the hole in the valve body 411. When the flow rate of the cleaning liquid through the valve body 411 needs to be adjusted, the knob 401 is turned to engage the first gear 406 at the bottom of the first rotating shaft 402 with the second gear 409. At this time, the second gear 409 drives the second rotating shaft 410 at the top and the valve body 411 to rotate simultaneously, thereby connecting the holes of different sizes on the valve body 411 with the cross tube 407, thereby achieving the purpose of adjusting the flow rate of the cleaning liquid in the cross tube 407.

[0037] like Figure 6 and Figure 7As shown, the adjustment mechanism 6 includes a first sprayer 61 and a second sprayer 62. The first sprayer 61 and the second sprayer 62 both include a transfer tube 601, a first liquid inlet 602, a liquid outlet 603, a liquid outlet pipe 604, a blocking block 605, a spring 606, a block 607, a bolt 608 and an internal threaded ring 609. The transfer tube 601 is connected to the cross tube 407. The top of the transfer tube 601 is provided with a first liquid inlet 602, the bottom of the transfer tube 601 is provided with a liquid outlet 603, the top of the liquid outlet hole 603 is connected to the liquid outlet pipe 604, the inside of the liquid outlet pipe 604 is movably connected with the blocking block 605, the top of the blocking block 605 is fixedly connected to the spring 606, the top of the spring 606 is fixedly connected to the block 607, the top of the block 607 is fixedly connected to the bolt 608, and one side of the bolt 608 is threadedly sleeved with an internal threaded ring 609.

[0038] The first sprayer 61 and the second sprayer 62 further include a liquid storage tube 610 , a second liquid inlet hole 611 and an atomizer 612 . The liquid storage tube 610 is connected to the liquid outlet tube 604 . A second liquid inlet hole 611 is provided on one side of the liquid storage tube 610 . An atomizer 612 is provided on one side of the liquid storage tube 610 .

[0039] The blocking block 605 is movably connected to one side of the liquid storage tube 610 , the second liquid inlet hole 611 is connected to the liquid outlet tube 604 , the internal threaded ring 609 is fixedly connected to the inside of the liquid outlet tube 604 , and the stopper 607 is movably connected to the inside of the liquid outlet tube 604 .

[0040] It needs to be further explained that: when the washing liquid inside the cross tube 407 enters the transfer tube 601, the washing liquid first enters the interior of the transfer tube 601 through the first liquid inlet hole 602, and then enters the bottom of the liquid outlet pipe 604 through the liquid outlet hole 603. As the washing liquid pressure inside the liquid outlet pipe 604 increases, the blocking block 605 is gradually pushed upward by the washing liquid until the washing liquid can enter the interior of the liquid storage tube 610 through the second liquid inlet hole 611, and then sprayed onto the inner wall of the phosphoric acid concentration tank body 1 through the atomizer 612; when the washing liquid is required to push the blocking block 605 with less force, the spring 606 and the blocking block 605 can be driven to move toward the direction of the internal threaded ring 609 by rotating the bolt 608. At this time, the distance between the blocking block 605 and the second liquid inlet hole 611 is reduced, and the washing liquid can push the blocking block 605 with less force, thereby making it easier to enter the interior of the second liquid inlet hole 611.

[0041] Working principle and usage flow of the present invention: During use, when the interior of the phosphoric acid concentration tank body 1 needs to be cleaned, the water pump 2 pumps cleaning liquid into the interior of the cross tube 407. Then, by manually pulling the knob 401, the sealing cover 403 is driven to separate from the sealing sleeve 404. At this time, the cleaning liquid can pass through the hole in the sealing sleeve 404 to the side of the valve body 411, and then enter the first sprayer 61 and the second sprayer 62 through the hole in the valve body 411.

[0042] Next, when it is necessary to adjust the flow rate of the washing liquid through the valve body 411, the knob 401 is turned to drive the first gear 406 at the bottom of the first rotating shaft 402 to engage with the second gear 409. At this time, the second gear 409 drives the second rotating shaft 410 at the top and the valve body 411 to rotate simultaneously, thereby connecting the holes of different sizes on the valve body 411 with the cross tube 407, thereby achieving the purpose of adjusting the flow rate of the washing liquid inside the cross tube 407.

[0043] Next, when the washing liquid in the cross tube 407 enters the transfer tube 601, the washing liquid first enters the interior of the transfer tube 601 through the first liquid inlet hole 602, and then enters the bottom of the liquid outlet pipe 604 through the liquid outlet hole 603. As the washing liquid pressure in the liquid outlet pipe 604 increases, the blocking block 605 is gradually pushed upward by the washing liquid until the washing liquid can enter the interior of the liquid storage pipe 610 through the second liquid inlet hole 611, and then sprayed onto the inner wall of the phosphoric acid concentration tank body 1 by the atomizer 612.

[0044] Finally, when the washing liquid is required to push the barrier block 605 with less force, the spring 606 and the barrier block 605 can be driven to move in the direction of the internal threaded ring 609 by rotating the bolt 608. At this time, the distance between the barrier block 605 and the second liquid inlet hole 611 is reduced, and the washing liquid can push the barrier block 605 with less force, thereby more easily entering the interior of the second liquid inlet hole 611. Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
