[0022] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0023] Example 1: A bottom stirring device for a desulfurization tower

[0024] It includes a mounting frame 1 installed on the tank body (tower body), the mounting frame 1 is a long strip or waist-shaped structure extending vertically along the length direction of the tank body (tower body), the mounting frame 1 extends horizontally and passes through the side wall of the tank body (tower body) and is fixed, and the outside of the mounting frame 1 protrudes from the side wall of the tank body (tower body).

[0025] Specifically:

[0026] The mounting frame 1 has a frame opening that passes through it, and one end face of the mounting frame 1 passes through and is fixed on the side wall of the tank body. The other end of the mounting frame 1 is arranged outside the tank body and is provided with a slot 2. The slot 2 is a through slot with both ends passing through the upper and lower ends of the mounting frame 1. A sealing plate 4 corresponding to its size is provided in the slot 2. The sealing plate 4 is long and narrow, and the width of the sealing plate 4 is adapted to the width of the slot 2. A step structure is formed between the slot 2 and the side walls of the mounting frame 1 on both sides. A sealing gasket is fixed on the step structure, and a sealing gasket is provided on the side of the sealing plate 4 close to the bottom of the slot 2.

[0027] The two sides of the described mounting frame 1 are symmetrically provided with slide grooves 5, and the length direction of the described slide groove 5 corresponds to the length direction of the mounting frame 1 and is also a through groove. The upper and lower ends of the mounting frame 1 are all open. The described mounting frame 1 is provided with a fixing seat that is movably plugged in and slides up and down with it. The fixing seat includes a cross plate 6 and a slide plate 7. The two sides of the cross plate 6 are respectively fixedly connected to one side of the slide plate 7 vertically, so that the fixing seat is a door-shaped structure. The opposite inner sides of the slide plate 7 are respectively provided with protrusions 8 that cooperate with the slide groove 5. The protrusions 8 can both slide and adjust the position in the slide groove 5 and limit the fixing seat. When the protrusions 8 of the fixing seat are inserted into the slide groove 5, the fixing seat can only be adjusted up and down. The middle part of the described cross plate 6 is provided with a screw sleeve 9 that passes through it vertically. The screw sleeve 9 is threaded with a large bolt 10. The inner end of the large bolt 10 is used to abut against the outer side of the sealing plate 4, thereby tightly pressing the sealing plate 4 to the frame opening of the mounting frame 1. The fixing seats can be provided in plurality as needed. When the rotating shaft 11 is located in the middle of the mounting frame 1, fixing seats can be added above and below the rotating shaft 11 respectively. When the rotating shaft 11 is located at the upper end or the lower end, as many fixing seats as possible can be installed while avoiding the rotating shaft 11.

[0028] A bearing seat is provided in the middle of the sealing plate 4, and a rotating shaft 11 connected to the bearing seat is passed through the bearing seat. The outer end of the rotating shaft 11 can be connected to the motor through a transmission structure to realize an active rotation function driven by a motor. The length of the sealing plate 4 is about twice the length of the mounting frame 1, so that when the height position of the sealing plate 4 relative to the mounting frame 1 is adjusted, the height of the rotating shaft 11 can be adjusted to obtain the flap and stirring effects at different positions. According to the material thickness, boundary position, pile height, process requirements, etc., the stirring height is adjusted accordingly to improve the stirring effect and ensure the uniformity of dispersion.

[0029] The inner end of the rotating shaft 11 is provided with a mounting head 12, and the mounting head 12 is a T-shaped head. A mounting rod 13 is symmetrically installed and fixed on the mounting head 12. The mounting rod 13 is a straight rod and is arranged perpendicular to the rotating shaft 11. A blade 14 is provided at the end of the mounting rod 13. The blade 14 is a flat plate structure. After installation, the middle part of the blade 14 is located in the middle of the tank body. The blade 14 realizes a stirring effect of up and down stirring based on the rotation of the rotating shaft 11, and has a good mixing effect on the upper and lower reaction phases.

[0030] Based on the above structure, blades 14 of different widths can be replaced as needed. Since the maximum distance between the two connecting rods is less than the length of the frame opening, the sealing plate 4 and the rotating shaft 11 can be easily removed. In this way, the stirring capacity and effect can be changed according to process needs within a single set of equipment, reducing configuration costs.

[0031] This device provides a removable stirring structure. By removing the fixing base, the sealing plate 4 can be quickly removed, sealing the mounting frame 1, and flexibly selecting whether to add a stirring structure. After installation, a height-adjustable flap structure can be obtained at the bottom of the reaction tank, which can effectively mix the reaction phases at different levels and facilitate a full reaction.

[0032] Example 2: A bottom stirring device for a desulfurization tower

[0033] It includes a relatively symmetrical mounting frame 1 mounted on the tank body. Based on the setting of the two mounting frames 1, other components cooperating with the mounting frame 1 are also two relative sets, including: a sealing plate 4, a fixing seat, a rotating shaft 11, blades 14, etc.

[0034] The blades 14 on both sides are respectively a first blade 14 and a second blade 14, one end of the first blade 14 is fixed to the mounting rod 13 on the same side by a screw, an end of the first blade 14 away from the mounting rod 13 is provided with an insertion strip 15, one end of the second blade 14 is fixed to the mounting rod 13 on the same side by a screw, and an end of the second blade 14 away from the mounting rod 13 is provided with a positioning groove 16, the insertion strip 15 and the positioning groove 16 are movably plugged into each other, and the insertion strip 15 and the positioning groove 16 are both located at the radial position in the center of the tank body. By plugging in, the first blade 14 and the second blade 14 on both sides form an elongated blade 14, and obtain synchronous rotation, and the side of the insertion strip 15 close to the second blade 14 is a wedge-shaped head obtained by a chamfered structure, which is convenient for inserting into the positioning groove 16.

[0035] In terms of power, the rotating shafts 11 on both sides can be equipped with motors respectively, or only one motor can be installed, and the other side is driven to rotate through the positioning of the first blade 14 and the second blade 14.

[0036] During actual use, the sealing plates 4 on both sides are fixed at the same height in the mounting frame 1 on the corresponding side, and then the first blades 14 and the second blades 14 on the rotating shafts 11 on both sides are plugged into each other through adjustment.
