Description

Technical Field

[0001] The utility model belongs to the technical field of phosphogypsum waste residue crushing equipment, and specifically relates to a phosphogypsum waste residue crusher. Background Art

[0002] While phosphorus chemical companies provide society with useful phosphorus chemical products, they also produce a large amount of industrial waste phosphogypsum. After crushing, these waste phosphogypsum can be used to produce hydraulic gel materials or be processed into cement retarders.

[0003] Since phosphogypsum is produced from the filtration stage of phosphoric acid production during the production process, the phosphogypsum waste residue usually contains a certain amount of free water, with a moisture content of about 10%-30%. During the crushing process, the phosphogypsum waste residue with a certain humidity not only causes the phosphogypsum to form a compaction, increasing the difficulty of crushing, but also the phosphogypsum waste residue with too high humidity (such as soluble phosphorus in impurities, etc.) is easy to stick to the components of the crushing equipment, thereby increasing the risk of equipment blockage.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0027] It is worth noting that the arrangement spacing and blade size of each crushing knife 4 on the mounting cylinder 3 can be selected according to the size of the particles to be crushed, and are not specifically limited here.

[0028] See also Figure 2-Figure 6The heating assembly shown in the figure includes a fixed plate 701 fixedly connected to the side of the crushing box 101 away from the rotating motor 6, the fixed plate 701 is provided with a heating fan 702, the output end of the heating fan 702 is connected to a connecting pipe 703, the other end of the connecting pipe 703 is fixedly connected to a first U-shaped tube 704, the two rotating rods 2 are provided with a heating chamber 705, and the side walls of the two heating chambers 705 are provided with a plurality of through holes 706. The crushing box 101 is provided with a recovery assembly for recovering the waste heat in the heating chamber 705. The ends of the two rotating rods 2 close to the first U-shaped tube 704 are rotatably connected to a connecting ball 707, and the two ends of the first U-shaped tube 704 are respectively connected to the two connecting balls 707;

[0029] It should be noted here that: by setting up the heating component, the sticky adhesion of phosphogypsum can be effectively reduced, thereby improving the surface cleanliness of the crushing knife 4 while improving the fluidity of the crushed phosphogypsum waste residue, thereby reducing the risk of blockage during the crushing process of the phosphogypsum waste residue.

[0030] See also Figure 3 、 Figure 5 and Figure 6 The recycling assembly shown in the figure includes two groups of multiple support rods 801 fixedly connected to the crushing box 101 near the side of the heating fan 702, and the other end of each support rod 801 is provided with a connecting ring 802, and the two connecting rings 802 are rotatably connected to the side wall of the rotating rod 2.

[0031] It should be noted here that: by setting up the recovery component, the waste heat is recycled and utilized, reducing heat waste.

[0032] Working principle: When crushing phosphogypsum waste residue, the two rotating motors 6 are started to drive the mounting cylinders 3 on the two rotating rods 2 to rotate in opposite directions, thereby driving the respective crushing knives 4 on the two mounting cylinders 3 to rotate in opposite directions. During the rotation of the respective crushing knives 4, the phosphogypsum waste residue is fed into the feed channel 102 from the conical feed port 103. During the process of the phosphogypsum waste residue entering the feed channel 102, the phosphogypsum waste residue is pre-treated under the cooperation of the processing component and the linkage component, thereby reducing the risk of phosphogypsum waste residue agglomeration.

[0033] After the phosphogypsum waste residue has been pre-treated, it will enter the crushing box 101 under the action of gravity and fall between the two sets of crushing knives 4. Thus, under the crushing action of the two sets of crushing knives 4, the phosphogypsum waste residue is crushed. The crushed phosphogypsum waste residue will be discharged from the discharge port at the bottom of the crushing box 101, thus completing the crushing operation of the phosphogypsum waste residue.

[0034] During the process of the two groups of crushing knives 4 crushing the phosphogypsum waste residue, the heating fan 702 is started to transport the heated air from the connecting pipe 703 to the first U-shaped tube 704, and finally transported to the heating chamber 705 of the rotating rod 2 through the connecting ball 707, and then flows from the through hole 706 on the side wall of the heating chamber 705 to the installation cylinder 3, so as to heat the installation cylinder 3, and then under the action of heat conduction, each crushing knife 4 is heated. When the surface temperature of each crushing knife 4 rises, the moisture brought by the phosphogypsum waste residue on its surface will evaporate rapidly, thereby effectively reducing the sticky adhesion of the phosphogypsum, thereby improving the cleanliness of the surface of the crushing knife 4 and improving the fluidity of the crushed phosphogypsum waste residue, thereby reducing the risk of blockage in the crushing process of the phosphogypsum waste residue;

[0035] In the process of transporting the hot air to the inside of the installation tube 3, when the air pressure inside the installation tube 3 increases to a certain level, the hot air will be squeezed from the heat return channel 803 on the side wall of the rotating rod 2 into the connecting ring 802 under the action of pressure, and finally use the suction force of the air inlet end of the heating fan 702 to flow back into the heating chamber 705 again, thereby realizing the recovery and utilization of waste heat and reducing heat waste.

[0036] Example 2

[0037] See also Figure 1 and Figure 4 , this embodiment further explains Example 1, the processing assembly in the figure includes a processing rod 901 rotatably connected to the feeding channel 102, the processing rod 901 is located on the side wall inside the feeding channel 102 and is fixedly connected to a plurality of separation rods 902, the processing rod 901 is connected to one of the two rotating rods 2 through a linkage assembly, the linkage assembly includes a first sprocket 1001 provided on one of the two rotating rods 2 and a second sprocket 1002 of the processing rod 901, and the first sprocket 1001 and the second sprocket 1002 are connected by a chain 1003;

[0038] Working principle: Through the setting of the processing component, in the process of the phosphogypsum waste slag entering the feed channel 102 from the conical feed port 103, the rotating motor 6 is started. In the process of the rotating motor 6 driving the rotating rod 2 to rotate, the various separation rods 902 on the processing rod 901 will be driven to rotate through the linkage component, so that in the process of the rotation of each separation rod 902, the phosphogypsum waste slag passing through the feed channel 102 is stirred, and then used to separate the agglomerated phosphogypsum waste slag, so that the phosphogypsum waste slag can be dispersed and fall into the crushing box 101, thereby realizing the pretreatment of the phosphogypsum waste slag before crushing, and reducing the increase in crushing difficulty caused by the agglomeration of the phosphogypsum waste slag.
