Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization, in particular to an automatic loading and unloading system for dry desulfurization. Background Art

[0002] The dry desulfurization process uses a large amount of desulfurizer, which is generally purchased from outside and transported to the site of use in the form of ton bags. The used desulfurizer is recycled by the supplier and must also be packed into ton bags. There are currently two ways to add desulfurizer to the tower: the first is to add the desulfurizer to the tower manually with the help of tools such as hoists and cranes, which will generate a lot of labor and have low efficiency; the second is to add the desulfurizer in the ton bag to a steel tank for storage, and then use equipment such as bucket elevators to automatically add it to the tower when it is used. Waste recycling also uses scrapers, bucket elevators and other equipment to recycle to the waste bin. The process can be automated, but dust will be generated during the transportation of the desulfurizer, and the bucket elevator will get stuck, and it is difficult to repair, which will affect the normal operation of the desulfurization equipment.

[0003] At present, with the improvement of environmental protection requirements and the development of various industries, the utilization rate of energy in energy-consuming industries has gradually increased. The dry desulfurization process is favored by the market because of its advantages of low temperature drop during operation, the flue gas after treatment still carries a lot of heat, and recycling can improve the utilization rate of energy and reduce operating costs. The existing loading and unloading system of dry desulfurization mainly involves more manual participation, and the bucket elevator with a higher degree of automation is easy to get stuck during operation, and the operation is not smooth. Summary of the invention

[0004] The utility model aims to provide an automatic loading and unloading system for dry desulfurization which can cooperate with a dry desulfurization tower to automatically operate, requires less manual intervention, is easy to maintain, has high loading and unloading efficiency, and is not prone to generating dust.

[0005] The automatic loading and unloading system of the utility model for dry desulfurization is realized in this way, including a loading system and a unloading system. The loading system includes a loading roller table, a loading device, a fixed conveyor belt mechanism, and a mobile conveyor belt mechanism. A new desulfurizer ton bag is placed on the loading roller table manually with the help of tools. When feeding is required, the loading roller table is operated, and the new desulfurizer ton bag is transported to a fixed position, and then the new desulfurizer ton bag is lifted by the loading device and moved to the top of the fixed conveyor belt. The loading device has a visual robot function and an automatic unpacking function, which can automatically identify the new desulfurizer ton bag and pass it. The lifting lugs of the feeding device accurately lift the new desulfurizer ton bag to the top of the fixed conveyor belt entrance, and then the feeding device automatically unlocks the discharge port at the bottom of the ton bag using its automatic unfastening function to discharge the new desulfurizer in the new desulfurizer ton bag to the entrance of the fixed conveyor belt in transmission operation. The fixed conveyor belt delivers the new desulfurizer to the mobile conveyor belt mechanism, and then the mobile conveyor belt mechanism delivers the new desulfurizer to the entrance of the chamber of the dry desulfurization tower where the desulfurizer needs to be added, and the new desulfurizer is delivered into the chamber of the dry desulfurization tower through the entrance from the exit of the mobile conveyor belt mechanism;

[0006] The unloading system includes a fixed unloading conveyor belt, a ton bag packaging machine, and a unloading roller table located below the waste desulfurizer outlet at the bottom of the chamber of the dry desulfurization tower. After the unloading valve of the waste desulfurizer outlet at the bottom of the chamber of the dry desulfurization tower is opened, the waste desulfurizer falls into the fixed unloading conveyor belt, and the fixed unloading conveyor belt conveys the waste desulfurizer to the ton bag packaging machine. The ton bag packaging machine with visual robot function and automatic bag hanging function automatically packs the waste desulfurizer, and places it on the unloading roller table after packaging. The packaged desulfurizer is manually transported to the waste desulfurizer storage area for storage, and will be recycled by the desulfurizer supplier when a new desulfurizer is purchased next time.

[0007] The technology of the patent application, after the new desulfurizer ton bag is placed on the feeding roller table, the feeding device automatically unfastens the bottom discharge port of the new desulfurizer ton bag by using its automatic unfastening function to discharge the material, and the new desulfurizer in the new desulfurizer ton bag is put into the entrance of the fixed conveyor belt in transmission operation, and then the new desulfurizer is delivered to the entrance of the chamber where the desulfurizer needs to be added by the mobile conveyor belt mechanism. Therefore, it can cooperate with the automatic operation of the dry desulfurization tower, with less manual intervention, easy maintenance, and high loading and unloading efficiency. Moreover, the new desulfurizer ton bag is discharged by automatically unfastening the bottom discharge port of the ton bag through the automatic unfastening function, and the bottom discharge port of the ton bag is short from the entrance of the fixed conveyor belt, so it is not easy to generate dust.

[0008] Compared with the prior art, the utility model has the advantages of being able to automatically operate in conjunction with a dry desulfurization tower, requiring less manual intervention, being easy to maintain, having high loading and unloading efficiency, and not easily generating dust.

DETAILED DESCRIPTION

[0013] The automatic loading and unloading system of the utility model for dry desulfurization is now described in further detail in conjunction with the accompanying drawings and embodiments:

[0014] like Figure 1-3 As shown, the automatic loading and unloading system of the dry desulfurization of the utility model includes a loading system a and a unloading system b. The loading system a includes a loading roller table 1, a loading device 2 located next to the loading roller table 1 (the technology of CN2019208658116 can be used), and a fixed conveying belt mechanism 3 located below the loading device 2 (such as Figure 2As shown, it includes several inclined conveyor belt mechanisms 301, a horizontal conveyor belt mechanism 302 connecting two adjacent inclined conveyor belt mechanisms 301 head to tail, and a mobile conveyor belt mechanism 5 located below the outlet of the fixed conveyor belt mechanism 3 and above the top entrance 4 of the chamber C of the dry desulfurization tower. A new desulfurization agent ton bag D is manually placed on the feeding roller table 1 with the help of tools. When feeding is required, the feeding roller table 1 is operated to transport the new desulfurization agent ton bag D to a fixed position, and then the new desulfurization agent ton bag D is lifted by the feeding device 2 and moved to the top of the fixed conveyor belt 3. The feeding device 2 has a visual robot function and an automatic unpacking function, which can automatically identify the new desulfurization agent ton bag D, and accurately lift the new desulfurization agent ton bag D to the top of the entrance of the fixed conveyor belt 3 through the lifting ears of the feeding device 2. Then the feeding device 2 uses its automatic unbuttoning function to automatically unbutton the bottom discharge port of the new desulfurizer ton bag D to discharge the material, and put the new desulfurizer in the new desulfurizer ton bag D into the entrance of the fixed conveyor belt 3 in transmission operation, and the fixed conveyor belt 3 sends the new desulfurizer to the mobile conveyor belt mechanism 5, and then the mobile conveyor belt mechanism 5 sends the new desulfurizer to the entrance 4 of the chamber C of the dry desulfurization tower where the desulfurizer needs to be added, and puts the new desulfurizer into the chamber C of the dry desulfurization tower through the entrance from the exit of the mobile conveyor belt mechanism 5. After the feeding device 2 discharges the new desulfurizer in the new desulfurizer ton bag D, it will put the ton bag aside, and then it is necessary to manually tie the discharge port at the bottom of the ton bag and fold it neatly and place it in the designated position next to the ton bag packaging machine of the unloading system. This process requires manual intervention;

[0015] The unloading system b includes a fixed unloading conveyor belt 7 located below the waste desulfurizer outlet 6 at the bottom of the chamber C of the dry desulfurization tower E, a ton bag packaging machine 8 located at the outlet of the fixed unloading conveyor belt 7, and a unloading roller table 9 located below the ton bag packaging machine 8. After the unloading valve of the waste desulfurizer outlet 6 at the bottom of the chamber C of the dry desulfurization tower E is opened, the waste desulfurizer falls into the fixed unloading conveyor belt 7, and the fixed unloading conveyor belt 7 delivers the waste desulfurizer to the ton bag packaging machine 8. The ton bag packaging machine 8 with a visual robot function and an automatic bag hanging function automatically packs the waste desulfurizer, and places it on the unloading roller table 9 after packaging. The packaged desulfurizer is manually transported to the waste desulfurizer storage area for storage, and will be recycled by the desulfurizer supplier when a new desulfurizer is purchased next time.
