Description

Technical Field

[0001] The present invention relates to the field of environmental protection technologies, and particularly to a durable slurry atomization disk with a single ceramic wear-resistant block. Background Art

[0002] A lime slurry atomizer is a device that can efficiently convert lime slurry into fine droplets. It mainly has two working modes: rotary centrifugal and gas-liquid two-phase flow atomization. The former drives the atomization disk to rotate at a high speed by an electric motor, and uses centrifugal force to form droplets of the slurry; the latter mixes compressed air or steam with the slurry in the nozzle, and realizes atomization through the shearing and tearing actions of the air flow. It has the characteristics of small atomization particle size and adjustable flow rate, and is widely used in fields such as flue gas desulfurization and waste incineration tail gas treatment. It can effectively remove acidic gases and reduce pollutant emissions, playing an important role in environmental protection.

[0003] The core component of the lime slurry atomizer is the slurry atomization disk. Currently, during the process of removing the slurry atomization disk, a 5T three-jaw puller is used to pull and remove the atomization disk. Stress will be generated when removing the atomization disk, and during the installation process, an impact force will be generated when the atomization disk is installed on the main shaft. Since the force used cannot be reasonably controlled, the original integral silicon carbide or ceramic atomization wear-resistant disk is very likely to vibrate and crack, reducing the service life of the atomization disk, being unfavorable for the use of the slurry atomization disk, and affecting the working efficiency of waste treatment work such as flue gas desulfurization.

[0032] Furthermore, a rotating rod 12 is rotatably installed on the upper surface of the installation plate 5. The lower end of the rotating rod 12 rotates through to the inside of the installation groove 11. A bevel gear 13 is fixedly installed at the lower end of the rotating rod 12. A bevel gear 13 of the same kind is fixedly installed on the outer surface of a section of the bidirectional threaded rod 10 located inside the installation groove 11. The two bevel gears 13 are meshed with each other.

[0033] Furthermore, by equally dividing the lower ceramic wear-resistant blocks 4 into eighteen parts and installing them on the disc body 1, and with the arrangement of the installation plate 5, when a certain lower ceramic wear-resistant block 4, the flow guide rod 15 or the upper ceramic wear-resistant block 17 has a problem, in cooperation with the installation plate 5, only the corresponding component needs to be replaced individually, without the need for large-scale disassembly and replacement of the entire disc body, reducing the maintenance cost and difficulty, thereby improving the use efficiency of the slurry atomization disc.

[0034] Furthermore, limiting grooves 14 are formed on the upper surfaces of the eighteen lower ceramic wear-resistant blocks 4. Flow guide rods 15 are inserted into the eighteen limiting grooves 14. Connection holes 16 are formed on the lower surface of the disc body 1 corresponding to the positions of the eighteen lower ceramic wear-resistant blocks 4. The upper ends of the eighteen connection holes 16 respectively penetrate to the upper surfaces of the corresponding flow guide rods 15. Upper ceramic wear-resistant blocks 17 are inserted on the outer surfaces of the upper ends of the eighteen flow guide rods 15. Limiting grooves 14 of the same kind are formed on the lower surfaces of the eighteen upper ceramic wear-resistant blocks 17.

[0039] Further, when using this slurry atomization disk and needing to replace the lower ceramic wear-resistant block 4, the replacement guide rod 15 or the upper ceramic wear-resistant block 17, first use an Allen wrench to disassemble the eighteen connecting screws 20, so that the eighteen connecting screws 20 loosen the fixing disk 18. At this time, the fixing disk 18 can be removed, and then the auxiliary replacement mechanism is sleeved on the outer surface of the connecting shaft 2. At this time, the staff can operate the mounting plate 5 through the rectangular slots 21 opened on the left and right surfaces of the disk body 1, so that the notch on the mounting plate 5 aligns with the position of the component to be replaced.

The bevel gear 13 at the lower end of the rotating rod 12 meshes with the bevel gear 13 on the bidirectional threaded rod 10, driving the bidirectional threaded rod 10 to rotate. When the bidirectional threaded rod 10 rotates, the connecting plates 9 threadedly connected to its left and right ends move towards or away from each other in the L-shaped slots 8. The movement of the connecting plates 9 will drive the ejector rods 6 fixed to them to move, so that the two ejector rods 6 drive the corresponding rubber pads 23 to extend out of the circular slots 7, clamp the outer surface of the connecting shaft 2, and fix the mounting plate 5. The position of the component that does not need to be replaced is fixed and limited through the mounting plate 5. At this time, a three-jaw puller can be used to replace the components at the position to be replaced, the lower ceramic wear-resistant block 4, the guide rod 15 or the upper ceramic wear-resistant block 17. If other components need to be replaced, the rotating rod 12 can be rotated to loosen the mounting plate 5 and rotate it so that its notch aligns with the position of other components to be replaced. After the replacement is completed, the mounting plate 5 is removed, and the fixing disk 18 is fixed through the connecting screws 20 to install the atomization disk.
