Description

Technical Field

[0001] The utility model belongs to the technical field of acid mist treatment, and in particular relates to an acid mist treatment device for pickling. Background Art

[0002] Acid mist usually refers to misty acidic substances. The particles of acid mist in the air are very small, smaller than those of water mist, and higher in humidity than smoke. It is a substance between smoke and water mist, and is highly corrosive. It includes acid mist formed by inorganic acids such as sulfuric acid, nitric acid, and hydrochloric acid, and organic acids such as formic acid, acetic acid, and propionic acid. In the galvanizing process, the workpiece to be processed needs to be pickled on the surface. The current method is to immerse the workpiece in acid solution to allow the acid solution to react with the surface of the workpiece. The pickling tank contains a small amount of acid mist. The amount of acid will increase when the workpiece is immersed in the pickling tank or taken out of the pickling tank. A large amount of acid mist dissipated into the atmosphere will have a significant impact on the environment. Therefore, a device for treating the acid mist generated by pickling processing is needed.

[0003] The current acid mist treatment equipment generally has a technical defect when treating acid mist, that is, the degree of mixing of the acid mist and the alkali solution in the air is not sufficient, resulting in insufficient efficiency of the alkali solution in treating the acid mist.

[0004] Therefore, an acid mist treatment device for pickling has been developed, which can fully mix the acid mist in the air and improve the treatment efficiency of the acid mist by alkali solution. Utility Model Content

[0012] The beneficial effects of the utility model are:

[0013] 1. The end of the liquid delivery hard pipe described in the utility model away from the liquid suction pump is connected with a liquid delivery hose, and a transmission gear is arranged on the liquid delivery hard pipe below the liquid delivery hose, and the transmission gear has a transmission rack, and one end of the transmission rack is provided with an electric telescopic rod. When the acid mist treatment is working, the electric telescopic rod allows the transmission rack to perform horizontal reciprocating motion, and the transmission rack drives the transmission gear meshing with it to perform horizontal reciprocating rotation. Under the movement of the transmission gear, the rolling bearing and the rotating liquid passage tube start to perform rotational reciprocating motion together, and a plurality of atomizing nozzles are arranged on the rotating liquid passage tube and move together with the rotating liquid passage tube.

An exhaust pipe is provided on the other side of the treatment chamber, and a negative pressure fan is provided at one end of the exhaust pipe.

There is a certain height difference between the air inlet pipe and the exhaust pipe. The acid mist sucked from the air inlet pipe falls from high to low. During the falling process of the acid mist, the atomizing nozzle releases the alkali solution in time, and further fully mixes the alkali solution and the acid mist to react, so as to avoid the acid mist being directly discharged from the exhaust pipe without purification under the action of the negative pressure fan, causing pollution to the external environment.

[0023] A liquid delivery hard pipe 4 is provided on the other side of the liquid pump 3. A liquid delivery hose 11 is connected to one end of the liquid delivery hard pipe 4 away from the liquid pump 3. A transmission gear 19 is provided on the liquid delivery hard pipe 5 below the liquid delivery hose 11. The transmission gear 19 is provided with a transmission rack 20. An electric telescopic rod 7 is provided at one end of the transmission rack 20. The transmission gear 19 matches the transmission rack 20. A mounting block 6 is fixedly provided on the left side of the rolling bearing 18 at the top of the processing chamber 1 to fix the electric telescopic rod 7 to prevent shaking. The electric telescopic rod 7 allows the transmission rack 20 to perform horizontal reciprocating motion, and the transmission rack 20 drives the transmission gear 19 meshing with it to perform horizontal reciprocating rotation. A rolling bearing 18 is fixedly provided on the top outer side of the processing chamber 1. The top end of the liquid delivery hard tube 5 below the tube 11 is connected to the outer ring of the rolling bearing 18, and the inner ring of the rolling bearing 18 is connected to the rotating liquid pipe 12, and the rotating liquid pipe 12 is connected to the inside of the treatment chamber 1. Under the action of the electric telescopic rod 7, the liquid delivery hard tube 5 below the liquid delivery hose 11 performs reciprocating rotation motion under the coordinated movement of the transmission gear 19 and the transmission rack 20. The rolling bearing 18 and the rotating liquid pipe 12 rotate back and forth continuously. A plurality of equidistant atomizing nozzles 13 are provided on the rotating liquid pipe 12. The plurality of rotating atomizing nozzles 13 can increase the area of ​​the acid mist in the alkali solution and acid mist treatment chamber 1, so that the mixing reaction of the alkali solution and the acid mist is more uniform and rapid, the mixing effect is better, and the acid mist treatment is more thorough.

[0024] An air inlet pipe 4 is provided at the top of one side of the outer wall of the treatment chamber 1, and the air inlet pipe 4 is arranged above the alkali solution storage box 2. An outer wall on the other side of the treatment chamber 1 is provided with an exhaust pipe 14, and a negative pressure fan 15 is provided at the end of the exhaust pipe 14. The air inlet pipe 4 and the exhaust pipe 14 are both connected to the inside of the treatment chamber 1. The negative pressure fan 15 introduces the acid mist in the air into the treatment chamber 1 through the air inlet pipe 4, so that the acid mist in the air is effectively mixed with the alkali solution in the treatment chamber 1. At the same time, there is a certain height difference between the air inlet pipe 4 and the exhaust pipe 14. The acid mist entering from the air inlet pipe 4 will fall from high to low. During the falling process of the acid mist, the atomizing nozzle 13 releases the alkali solution in time, and the alkali solution and the acid mist are fully mixed and reacted, which effectively avoids the acid mist that has not been purified being directly discharged to the outside from the exhaust pipe 14 under the action of the negative pressure fan 15, causing pollution to the external environment.

[0025] When the acid mist treatment begins, the first solenoid valve 8 is opened, the second solenoid valve 9 is closed, and the liquid extraction pump 3 and the electric telescopic rod 7 are opened at the same time. Under the action of the liquid extraction pump 3, the alkali solution passes through the liquid delivery hard pipe 5, the liquid delivery hose 11 and the rotating liquid pipe 12, and enters the treatment chamber 1 through the atomizing nozzle 13. At the same time, under the action of the electric telescopic rod 7, the transmission rack 20 and the transmission gear 19 cooperate with each other to perform horizontal reciprocating motion, thereby driving the rotating liquid pipe 12 and the atomizing nozzle 13 to rotate back and forth, spraying the alkali solution, and then turning on the negative pressure fan 15, the acid mist will enter the treatment chamber 1 through the air inlet pipe 4, and the rotating atomizing nozzle 13 will rotate back and forth to spray the alkali solution. The nozzle 13 will spray alkali solution evenly all around. At this time, the acid mist and alkali solution will undergo a fully and evenly mixed reaction in the treatment chamber 1, so that the acid in the acid mist can be removed. After the acid mist is completely treated, first turn off the first electromagnetic 8 and the negative pressure fan 15 to prevent the acid mist and alkali solution from entering the treatment chamber 1. After the alkali solution in the liquid delivery hard pipe 5 and the liquid delivery hose 11 reacts with the residual acid mist in the treatment chamber 1, turn off the liquid suction pump 3 and the electric telescopic tube 7, and the device stops working. The operator can open the control valve 17 to allow the waste liquid after the reaction at the bottom of the treatment chamber 1 to be discharged through the drain pipe 16 for centralized treatment.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
