The driving member includes a mounting block 107, a driving bar 108 and a driving element. The driving element includes a motor 109, mounting parts, a rotating wheel 110 and a connecting bar 111. The mounting parts include a support rod 112 and a mounting plate 113. By this solution, the problem that the two raw material tanks provided in the existing equipment greatly occupy the area of the desulfurization tower pit, making it inconvenient for workers to work inside the desulfurization tower pit, is solved, and it is also possible to facilitate the supply of air into the pressurizing cylinder 105.

[0021] For this specific embodiment, the connecting pipe 101 is fixedly connected to the box body 100 and is located below the box body 100. The chemical dosing tank 102 is fixedly connected to the connecting pipe 101 and is located on the side of the connecting pipe 101 away from the box body 100. The chemical dosing tank 102 is the synergist dosing tank 102 described in the existing patent technology CN216964138U, a new type of desulfurization synergist special dosing device. An internal centrifugal stirring structure is provided in the chemical dosing tank 102 to ensure uniform dissolution and diffusion of the chemical agent. The connecting pipe 101 is installed on the box body 100 through a threaded structure. A sealing cover is provided above the box body 100 for adding the synergist into the box body 100. The synergist is stored in the box body 100, and the synergist inside the box body 100 can enter the chemical dosing tank 102 through the connecting pipe 101. The chemical dosing tank 102 stirs the synergist and injects it into the desulfurization tower. By this solution, the floor area occupied by the desulfurization synergist dosing equipment is reduced, and the excessive occupation of the area of the desulfurization tower pit is avoided, thus facilitating the work of workers inside the desulfurization tower pit.

[0022] Among them, the fixed ring 103 is fixedly connected to the box body 100 and is located on the side of the box body 100 away from the communicating pipe 101.

The pressure cylinder 105 is fixedly connected to the first one-way valve 104 and is located on the side of the first one-way valve 104 away from the fixed ring 103. The sliding plate 106 is slidably connected to the pressure cylinder 105 and is located inside the pressure cylinder 105. The driving member is installed on the pressure cylinder 105, and the driving member drives the sliding plate 106 to move. The fixed ring 103 is installed above the box body 100 through a threaded structure. The first one-way valve 104 is the one-way valve described in the existing patent technology CN103438249A gas one-way valve. The first one-way valve 104 is installed above the fixed ring 103 away from the box body 100 through a threaded structure, so that air can enter the fixed ring 103 through the first one-way valve 104 and prevent air from flowing out of the fixed ring 103. The pressure cylinder 105 is installed in the first one-way valve 104 away from the fixed ring 103 through a threaded structure. The sliding plate 106 is slidably installed inside the pressure cylinder 105. By sliding the sliding plate 106, the air in the pressure cylinder 105 is injected into the interior of the box body 100 through the first one-way valve 104, thereby increasing the pressure inside the box body 100, so that the synergist inside the box body 100 enters the chemical addition tank 102 through the communicating pipe 101. The driving member is installed on the pressure cylinder 105, and the driving member drives the sliding plate 106 to move, avoiding adding the synergist to the chemical addition tank 102 through a turnover box, thereby reducing the floor area occupied by the desulfurization synergist dosing equipment and avoiding excessive occupation of the area of the desulfurization tower pit, thus facilitating the work of the staff inside the desulfurization tower pit.

By driving the driving bar 108 to drive the sliding plate 106 to move downward, the air in the pressure cylinder 105 is injected into the interior of the box body 100 through the first one-way valve 104, thereby increasing the pressure inside the box body 100. The driving element is mounted on the box body 100, and the driving element drives the driving bar 108 to move, so that the driving bar 108 drives the sliding plate 106 to move.

[0024] Meanwhile, the motor 109 and the box body 100 are connected through the mounting parts, and the mounting parts support the motor 109; the rotating wheel 110 is fixedly connected to the motor 109 and is located at the output end of the motor 109; the connecting bar 111 is rotatably connected to the rotating wheel 110, is located on the side of the rotating wheel 110 away from the motor 109, and is connected to the driving bar 108. The motor 109 is mounted above the box body 100 through the mounting parts, and the motor 109 is stably mounted above the box body 100 through the mounting parts. The rotating wheel 110 is fixedly mounted at the output end of the motor 109, and the motor 109 drives the rotating wheel 110 to rotate. The connecting bar 111 is mounted on the edge of the rotating wheel 110 through a bearing mounting seat, and the other end of the connecting bar 111 is mounted on the side of the driving bar 108 away from the sliding plate 106 through a bearing, so that when the rotating wheel 110 rotates, the driving bar 108 is driven to move up and down through the connecting bar 111, so that the driving bar 108 can drive the sliding plate 106 to move.

[0025] In addition, the support rod 112 is fixedly connected to the box body 100 and is located on one side of the box body 100 close to the fixed ring 103; the mounting plate 113 is fixedly connected to the support rod 112 and is located on the side of the support rod 112 away from the box body 100 and is connected to the motor 109. The support rod 112 is installed above the box body 100 by bolts, and the mounting plate 113 is installed on the side of the support rod 112 away from the box body 100 by bolts. The height of the mounting plate 113 is raised by the support rod 112, and the motor 109 is installed on the side of the mounting plate 113 away from the support rod 112 by bolts, so that the motor 109 can be located above the box body 100 and the motor 109 can drive the driving strip 108 to move.

[0026] When using the dosing agitator for desulfurization synergist of this embodiment, enough synergist is added into the interior of the box body 100 through the sealing cover arranged on the box body 100.

The motor 109 drives the rotating wheel 110 to rotate, and the rotating wheel 110 drives the driving teeth to move through the connecting strip 111, so that the sliding plate 106 moves downward, and thus the air in the pressurizing cylinder 105 is injected into the box body 100, increasing the pressure in the box body 100, so that the synergist enters the chemical dosing tank 102 through the communicating pipe 101, avoiding the use of an intermediate tank to add raw materials into the chemical dosing tank 102, further reducing the floor area occupied by the desulfurization synergist dosing equipment, avoiding excessive occupation of the area of the desulfurization tower pit, and thus facilitating the work of the staff inside the desulfurization tower pit.

[0027] The second embodiment of this application is as follows:

[0028] On the basis of the first embodiment, please refer to Figure 3 , Figure 3 which is a schematic installation diagram of the air exchange pipe and the second one-way valve of the second embodiment of the present utility model.

[0029] The pressurizing assembly of this embodiment further includes an air exchange pipe 214 and a second one-way valve 215.

[0030] Among them, the air exchange pipe 214 is fixedly connected to the pressure cylinder 105 and is located at one end of the pressure cylinder 105 away from the sliding plate 106; the second one-way valve 215 is fixedly connected to the air exchange pipe 214 and is located on one side of the air exchange pipe 214 away from the pressure cylinder 105. The air exchange pipe 214 is installed on the pressure cylinder 105 through a threaded structure, so that external air can enter the pressure cylinder 105 through the air exchange pipe 214, and then it is convenient to inject into the interior of the box body 100. The second one-way valve 215 is the one-way valve described in the prior patent technology CN103438249A gas one-way valve. Through the second one-way valve 215, it is avoided that air flows out of the air exchange pipe 214 when the sliding plate 106 moves. When the sliding plate 106 moves upward, air is added to the pressure box through the cooperation of the second one-way valve 215 and the air exchange pipe 214, so as to continuously pressurize the box body 100.

[0031] When using the dosing agitator of a desulfurization synergist in this embodiment, when the sliding plate 106 moves upward, due to the pressure relationship, air enters the pressure cylinder 105 from the second one-way valve 215 and the air exchange pipe 214. When the sliding plate 106 moves downward, the second one-way valve 215 locks the air, so that the air can only flow into the interior of the box body 100, thereby continuously pressurizing the box body 100.

[0032] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
