Technical Field

[0001] This utility model relates to the technical field of dust removal devices, and in particular to a dust removal device for activated carbon dispensing. Background Technology

[0002] In the production process of some chemical products, due to process and other factors, defects such as turbidity and flocculent suspended matter may occur in the mixing tank. Activated carbon must be added to the mixing tank to remove turbidity and ensure the quality of the finished product. However, the addition of activated carbon to the mixing tank generates dust. If the dust is not controlled, long-term exposure to dust will increase the risk of occupational diseases such as pneumoconiosis for workers, which is detrimental to their physical and mental health. Therefore, this application proposes a dust removal device for adding activated carbon. Utility Model Content

[0015] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be described in further detail.

[0016] In the first embodiment, the technical solution is as follows: During use, a spraying device 8 is fixedly installed in the dust collector 6 via a hanging rod 7 for dust removal. Before adding activated carbon to the mixing tank 1 through the activated carbon feeding pipe 2, the fan 4 and the liquid supply device 17 are started to facilitate timely treatment of the dust generated by the added activated carbon via the spraying device 8. The dust generated by the fan 4 is drawn into the dust collector 6 through the first air duct 3 and the second air duct 5. The dust entering the dust collector 6 is washed and adsorbed by the liquid sprayed by the spraying device 8, and discharged along with the liquid through the conical discharge pipe 9 to the right side chamber 12 of the impurity removal box 10. The adsorbed dust mixed in the liquid settles at the bottom of the impurity removal box 10, while the clear liquid is further processed through the filter screen 15 and then returned to the storage tank 26 of the liquid supply device 17 via the return pipe 16, facilitating liquid recycling and avoiding water waste. This application has a simple structure, is easy to use, and is highly practical.

[0017] In Example 2, based on Example 1, specifically, in this application, the storage tank 26 stores an appropriate amount of clean water liquid during use. When adding activated carbon to the mixing tank 1, the liquid supply device 17 and the blower 4 are started first. When starting the liquid supply, the solenoid valve 30 and the booster pump 28 of the liquid supply device 17 are opened. Under the action of the booster pump 28, the liquid in the storage tank 26 will enter the booster pump 28 through the first conduit 27 for pressurization. The pressurized liquid is then transported by the booster pump 28 through the second conduit 29 and the inlet pipe 25 into the outer ring pipe 22 of the spraying device 8, and then enters the inner ring pipe 21 through the connecting pipe 23. Under the continuous action of the booster pump 28, the inner ring pipe 21 and the outer ring pipe 22 will be filled with liquid and released from the nozzles 24 at their lower edges. The inner ring pipe 21 and the outer ring pipe 22 are coaxially arranged and both are equipped with nozzles 24 to ensure the spraying range of the liquid. To ensure effective dust removal, the liquid released from the nozzle 24 can flush and settle the activated carbon dust entering the dust collection cylinder 6. Specifically, the fan 4 draws the dust generated by the activated carbon from the first air duct 3 and the second air duct 5 into the dust collection cylinder 6. At this time, under the flushing and settling effect of the sprayed liquid, the dust will mix with the liquid and enter the right chamber 12 of the impurity removal box 10 from the conical discharge pipe 9, and spread to the left chamber 11 through the through hole 13. During this process, the dust mixed in the liquid will be deposited at the bottom of the impurity removal box 10, while the upper clear liquid will pass through the filter screen 15 on the mounting frame 14 and enter the return pipe 16, and then enter the storage tank 26 from the return pipe 16 for recycling.

[0018] In Example 3, based on Example 2, the sedimentation and filtration in the impurity removal box 10 ensure that the liquid passing through the return pipe 16 is free of impurities. When it is necessary to clean the dust accumulated at the bottom of the impurity removal box 10, while using an external water source to flush the bottom of the impurity removal box 10, the drain valve 20 is opened so that the accumulated dust can enter the wastewater tank 19 through the drain pipe 18.
