Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of acidic sludge treatment, and in particular to an acidic sludge treatment neutralization and stirring device. Background Technology
[0002] Acidic sludge is a common pollutant generated during industrial production. It has a complex composition and uneven acidity, and can easily cause secondary pollution if not handled properly. When neutralizing acidic sludge, stirring is a key step to ensure sufficient acid-base reaction and uniform acidity of the sludge.
[0003] In existing technologies, most mixing devices employ fixed or single-rotary mixing structures. However, in practical applications, the viscosity of acidic sludge varies. For sludge with low viscosity, conventional rotary mixing can meet the mixing requirements; but for sludge with high viscosity, its internal shear force is high and its fluidity is poor, making it difficult for single-rotary mixing to effectively break up sludge clumps and easily creating dead zones within the mixing tank. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an acidic sludge treatment neutralization and stirring device to solve the technical problems mentioned in the background art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] An acidic sludge treatment and neutralization mixing device includes a mixing tank. A support cylinder is fixedly connected to the bottom of the mixing tank. A rotating disk is rotatably connected to the bottom of the support cylinder. An annular groove is formed on the bottom of the inner circumference of the support cylinder. Ratchets are distributed in a ring array on the bottom of the outer circumference of the rotating disk. Pads are rotatably connected to the inner circumference of the annular grooves by torsion springs. The ends of the pads extend into the corresponding ratchet grooves. An inclined block is fixedly connected to the top of the rotating disk. A mixing mechanism is provided at the top of the support cylinder for treating the acidic sludge in the mixing tank. A driving mechanism is provided on the top side of the mixing tank for driving the mixing mechanism.
[0007] In a preferred embodiment, the present invention can be further configured as follows: the stirring mechanism includes a mounting ring, which is placed on the top of the support cylinder and the bottom of the mounting ring is convex. A number of bearing rods are fixedly connected to the outer periphery of the mounting ring. The bearing rods are L-shaped and their ends extend downward to the bottom of the stirring tank. A number of stirring blades are fixedly connected to each bearing rod.
[0008] In a preferred embodiment, the present invention can be further configured such that: a control shaft is fixedly connected to the inner circumference of the mounting ring, the bottom end of the control shaft extends above the rotating disk, and an abutment rod is fixedly connected to the bottom of the outer circumference of the control shaft, the end of the abutment rod being arc-shaped.
[0009] In a preferred embodiment, the present invention can be further configured such that: the driving mechanism includes a driving motor, the driving motor is fixedly connected to the middle of the top side wall of the mixing tank, and the output shaft of the driving motor extends into the mixing tank and is connected to the control shaft through a sliding structure.
[0010] In a preferred embodiment, the present invention can be further configured such that: the sliding structure includes a rectangular groove, the rectangular groove is opened at the top of the control shaft, a rectangular rod is fixedly connected to the end of the output shaft of the drive motor, the bottom end of the rectangular rod is inserted into the rectangular groove, and is slidably connected to the rectangular groove.
[0011] In a preferred embodiment, the present invention can be further configured such that the abutment rod is L-shaped and the end of the abutment rod extends to the top of the rotating disk, wherein the inclined block is on the rotation path of the end of the abutment rod.
[0012] In summary, this utility model has at least one of the following beneficial technical effects:
[0013] This acidic sludge treatment neutralization and mixing device utilizes the forward and reverse rotation of a drive motor to drive the mixing mechanism in two modes of mixing. For acidic sludge with lower viscosity, the drive motor can directly drive the mixing mechanism to mix the sludge. For acidic sludge with higher viscosity, the drive motor rotates in the reverse direction, allowing the mixing mechanism to further move up and down to mix the acidic sludge. This ensures that the acidic sludge is broken up and fully mixed, guaranteeing the acidity uniformity of the acidic sludge in the mixing tank. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.
[0021] Example:
[0022] Reference Figures 1-4 This utility model discloses an acidic sludge treatment neutralization and stirring device, including a stirring tank 1. A support cylinder 2 is fixedly connected to the bottom of the stirring tank 1. A rotating disk 3 is rotatably connected to the bottom of the support cylinder 2. An annular groove 4 is formed on the bottom of the inner circumference of the support cylinder 2. Ratchets 5 are arranged in an annular array on the bottom of the outer circumference of the rotating disk 3. A pawl 6 is rotatably connected to the inner circumference of the annular groove 4 by a torsion spring. The end of the pawl 6 extends into the corresponding ratchet 5. An inclined block 7 is fixedly connected to the top of the rotating disk 3. A stirring mechanism 8 is provided at the top of the support cylinder 2 for treating the acidic sludge in the stirring tank 1. A driving mechanism 9 is provided on the top side of the stirring tank 1 for driving the stirring mechanism 8.
[0023] In this embodiment, combined with Figure 1 A dedicated inlet for adding acidic sludge is opened at the top of the mixing tank 1 and a closed cover is provided. An inlet is opened at the bottom of the mixing tank 1, and its outlet is also provided with a closed cover. The specific opening and installation of the components are existing technologies, so they will not be described in detail.
[0024] After pouring the acidic sludge into the mixing tank 1, seal both the inlet and outlet. Then, start the drive mechanism 9. The drive mechanism 9 will drive the mixing mechanism 8 to rotate, which will stir the acidic sludge in the mixing tank 1 to balance the acidity of the sludge. The rotation of the mixing mechanism 8 will also contact the inclined block 7 on the top of the rotating disc 3 (in conjunction with...). Figure 4 );
[0025] If the acidic sludge has low viscosity, then the drive mechanism 9 drives the stirring mechanism 8 to rotate clockwise (in conjunction with...). Figure 1This causes the stirring mechanism 8 to directly contact the side of the inclined block 7. At this time, the inclined block 7 is pushed, which in turn drives the rotating disk 3 to rotate. During this stage, the pawl 6 is directly pushed by the inclined side wall of the ratchet groove 5, allowing it to rotate with the torsion spring (not shown in the figure, its installation method is to open a hole in the inner top side wall of the annular groove 4, fix a torsion spring in the hole, and then fix the torsion spring to the end of the pawl 6, so that the pawl 6 is limited by the torsion spring and fits against the inclined side wall of the ratchet groove 5). The torsion spring drives the pawl 6 to fit against the inclined side wall of the ratchet groove 5, thereby allowing the stirring mechanism 8 to rotate normally and stir the acidic sludge without being affected by the inclined block 7.
[0026] If the sludge is in a highly viscous state, the drive mechanism 9 drives the stirring mechanism 8 to rotate counterclockwise, so that the stirring mechanism 8 can be affected by the tilting block 7, allowing it to float up and down while stirring to increase the stirring range, thus avoiding excessively viscous sludge that would be difficult to break up and mix during stirring, affecting the acidity balance treatment of the sludge.
[0027] In a further preferred embodiment of this utility model, such as Figures 1-4 As shown, the stirring mechanism 8 includes a mounting ring 10, which is placed at the top of the support cylinder 2. The bottom of the mounting ring 10 is convex. A number of bearing rods 11 are fixedly connected to the outer periphery of the mounting ring 10. The bearing rods 11 are L-shaped and their ends extend downward to the bottom of the stirring tank 1. A number of stirring blades 12 are fixedly connected to each bearing rod 11. A control shaft 13 is fixedly connected to the inner periphery of the mounting ring 10. The bottom end of the control shaft 13 extends above the rotating disk 3. An abutment rod 14 is fixedly connected to the bottom of the outer periphery of the control shaft 13. The end of the abutment rod 14 is arc-shaped and L-shaped. The end of the abutment rod 14 extends to the top of the rotating disk 3. The inclined block 7 is on the rotation path of the end of the abutment rod 14.
[0028] In this embodiment, combined with Figure 1 and Figure 2 The drive mechanism 9 drives the control shaft 13 to rotate, which in turn drives the mounting ring 10 and the support rod 11 to rotate. The rotation of the support rod 11 drives the rotation of the stirring blade 12, thereby stirring the sludge. Figure 4The control shaft 13 has a contact rod 14 fixedly connected to its outer bottom. When the drive mechanism 9 rotates the control shaft 13 clockwise, the contact rod 14 directly abuts against the side wall of the inclined block 7, thereby directly driving the rotation of the rotating disk 3. The rotating disk 3 is not restricted by the pawl 6 when rotating, and the stirring blades 12 are in a smooth stirring state. If stirring sludge with high viscosity, the control shaft 13 rotates counterclockwise, and the bottom end of the contact rod 14 passes through the inclined surface of the inclined block 7, using the inclined surface of the inclined block 7 to squeeze... The contact rod 14 is pushed upward, which in turn pushes the mounting ring 10 upward, causing the mounting ring 10 to drive the bearing rod 11 upward. This causes the stirring blade 12 to float upward during the stirring process. When the bottom end of the contact rod 14 passes the inclined block 7, it moves downward using the gravity of the control shaft 13 (equivalent to a counterweight rod), which in turn drives the stirring blade 12 downward. This allows the stirring blade 12 to float up and down during the stirring process, increasing the stirring range and ensuring that the more viscous sludge is fully stirred, thus avoiding the phenomenon of uneven acidity.
[0029] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the driving mechanism 9 includes a driving motor 15, which is fixedly connected to the middle of the top side wall of the mixing tank 1. The output shaft of the driving motor 15 extends into the mixing tank 1 and is connected to the control shaft 13 through a sliding structure.
[0030] The sliding structure includes a rectangular groove 16, which is located at the top of the control shaft 13. A rectangular rod 17 is fixedly connected to the end of the output shaft of the drive motor 15. The bottom end of the rectangular rod 17 is inserted into the rectangular groove 16 and is slidably connected to the rectangular groove 16.
[0031] In this embodiment, combined with Figure 1 and Figure 2 The drive motor 15 is driven by the controller. The drive motor 15 drives the rectangular rod 17 to rotate, and the rectangular rod 17 drives the control shaft 13 to rotate. When the control shaft 13 slides up and down, it will allow the rectangular rod 17 to slide relative to the rectangular groove 16, thereby achieving the effect of facilitating the rotation of the control shaft 13.
[0032] The implementation principle of the above embodiment is as follows: the drive motor 15 is driven by the controller, the drive motor 15 drives the rectangular rod 17 to rotate, the control shaft 13 drives the mounting ring 10 and the bearing rod 11 to rotate, and the rotation of the bearing rod 11 drives the rotation of the stirring blade 12, thereby stirring the sludge. Figure 4The control shaft 13 has a contact rod 14 fixedly connected to its outer bottom. When the drive motor 15 rotates the control shaft 13 clockwise, the contact rod 14 directly abuts against the side wall of the inclined block 7, thereby directly driving the rotation of the rotating disk 3. The rotating disk 3 is not restricted by the pawl 6 when rotating, and the stirring blades 12 are in a smooth stirring state. If stirring sludge with high viscosity, the control shaft 13 rotates counterclockwise, and the bottom end of the contact rod 14 passes through the inclined surface of the inclined block 7, utilizing the inclination of the inclined block 7. The inclined plane presses against the contact rod 14, which is pushed upward, thereby pushing the mounting ring 10 upward. The mounting ring 10 then drives the bearing rod 11 upward, causing the stirring blade 12 to float upward during the stirring process. When the bottom end of the contact rod 14 passes the inclined block 7, it moves downward using the gravity of the control shaft 13, thereby driving the stirring blade 12 downward. This allows the stirring blade 12 to float up and down during the stirring process, increasing the stirring range and ensuring that the more viscous sludge is fully stirred, thus avoiding the phenomenon of uneven acidity.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
