Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing pickling technology, and in particular to an environmentally friendly hot-dip galvanizing pickling equipment. Background Technology

[0002] At the start of the hot-dip galvanizing production line process, metal workpieces are first cleaned in an pickling tank to remove surface oil, rust, and oxides. This step is crucial for ensuring the adhesion of the galvanized layer. The pickling solution usually uses hydrochloric acid or sulfuric acid, and hydrogen chloride waste gas is generated during the pickling process. This hydrogen chloride waste gas needs to be treated before it can be discharged.

[0003] The irritating gases produced during hot-dip galvanizing pickling can irritate the respiratory tract and cause harm to workers.

[0004] A publicly available technical solution, CN219239737U, discloses an environmentally friendly hot-dip galvanizing pickling equipment, including a hot-dip galvanizing pickling tank. The surface of the tank is equipped with a collection component for collecting ammonia and zinc oxide fumes generated during the hot-dip galvanizing pickling process. A collection pipe is fixedly installed on the surface of the tank via the collection component. A treatment component is located at the front of the tank to process the collected ammonia and zinc oxide fumes. This allows the collection pipe to collect the zinc oxide fumes and irritating ammonia gas generated during hot-dip galvanizing pickling. The collected zinc oxide fumes and ammonia are then processed within the treatment component, preventing harmful substances from harming workers and avoiding serious illnesses.

[0005] In actual implementation, the above technical solution uses a collection component to collect dust. However, during the pickling process, when the workpiece is immersed in the pickling liquid, it is easy to splash up, and the pickling liquid may enter the collection component, causing damage to the collection component.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 An environmentally friendly hot-dip galvanizing pickling equipment includes a pickling tank 1, a gas collection component 2 for collecting gas is provided on the pickling tank 1, a gas overflow prevention component 3 for preventing gas overflow is provided on the top of the pickling tank 1, and a workpiece lifting component 4 for adjusting the workpiece height is installed on the gas overflow prevention component 3, and a bottom plate 5 is fixedly provided at the bottom of the pickling tank 1.

[0028] The gas collection assembly 2 includes an air inlet 203 fixed to the inner wall of the pickling tank 1, and a support plate 204 fixedly installed below the air inlet 203. A baffle plate 205 is movably installed on the top of the support plate 204, and the baffle plate 205 is close to the air inlet 203. The gas collection assembly 2 also includes a connecting pipe 202 fixed to one side of the air inlet 203, and a collection chamber 201 is fixedly connected to the end of the connecting pipe 202. An air pump is installed inside the collection chamber 201.

[0029] By adopting the above technical solution, the workpiece is raised and lowered by the workpiece lifting assembly 4, so that the workpiece can come into contact with pickling solution of different depths, and the workpiece can fully come into contact with the pickling solution. When the workpiece is put into the pickling tank 1, the gas overflow prevention assembly 3 can block the pickling tank 1 to prevent gas from overflowing. At the same time, by starting the air pump, the air pump can draw the gas from the air inlet 203 into the interior of the connecting pipe 202, and then to the interior of the collection chamber 201 through the connecting pipe 202. When gas treatment is not required, the air inlet 203 can be blocked by the baffle plate 205. The baffle plate 205 and the air inlet 203 are in close contact to prevent hydrochloric acid and other substances from entering the air inlet 203. The bottom of the baffle plate 205 is provided with a support plate 204, which can support the baffle plate 205.

[0030] Specifically, such as Figure 4 As shown, the gas spill prevention assembly 3 includes a top cover 303 movably installed on the top of the pickling tank 1. A sealing plate 304 is provided at the connection between the top cover 303 and the pickling tank 1. Guide brackets 305 are slidably connected to the left and right sides of the top cover 303. A lifting slider 301 is fixedly welded to one side of the guide bracket 305. A lifting screw 302 is connected to the inside of the lifting slider 301 through a threaded sleeve.

[0031] The workpiece lifting assembly 4 includes a lifting cylinder 401 fixed to the top of the top cover 303. The telescopic end of the lifting cylinder 401 passes through the top cover 303 and the sealing plate 304 and is fixedly connected to a connecting bracket 403. Two sets of workpiece mounting plates 402 and two sets of guide sleeves 405 are arranged around the connecting bracket 403. The telescopic plate 404 is sleeved inside the guide sleeve 405, and the baffle plate 205 is fixed to the end of the telescopic plate 404.

[0032] By adopting the above technical solution, the lifting screw 302 is connected to the motor power output end. When the motor rotates, it drives the lifting screw 302 to rotate, which in turn drives the lifting slider 301 to move upward through the screw sleeve. This, in turn, drives the top cover 303 to move upward through the guide bracket 305. At this time, the sealing plate 304 on the top cover 303 leaves the pickling tank 1. When it is necessary to remove the workpiece, the top cover 303 can be pulled to slide inside the guide bracket 305, which facilitates the operation of the workpiece. To facilitate the installation of the workpiece, a ring can be set at the bottom of the workpiece mounting plate 402, and the workpiece is hung on the ring by a hook. Under the action of the gas overflow prevention component 3, the workpiece can be moved to the top of the pickling tank 1, and under the action of the lifting screw 302, the workpiece reaches the inside of the pickling tank 1. At this time, the lifting cylinder 401 can be activated, and the lifting cylinder 401 pushes the connecting bracket 40 3. Moving downwards, the connecting bracket 403 drives the guide sleeve 405 and the workpiece mounting plate 402 to descend simultaneously, causing the telescopic plate 404 on the guide sleeve 405 to move downwards until the baffle plate 205 reaches above the support plate 204. The baffle plate 205 blocks all the air inlets 203, and the workpiece is also immersed in the pickling solution. During the pickling process, when it is necessary to change the immersion depth of the workpiece, the lifting cylinder 401 can push the connecting bracket 403 to continue moving downwards. At this time, the workpiece continues to be immersed, while the guide sleeve 405 slides outside the telescopic plate 404. It should be noted that when the guide sleeve 405 and the telescopic plate 404 cannot be separated from each other, and the connecting bracket 403 is in the highest position, the baffle plate 205 is located above the air inlets 203 and cannot block the air inlets 203, which facilitates gas collection.

[0033] Working principle: The lifting screw 302 is connected to the motor power output end. When the motor rotates, it drives the lifting screw 302 to rotate, which in turn drives the lifting slider 301 to move upward through the screw sleeve. This, in turn, drives the top cover 303 to move upward through the guide bracket 305. At this time, the sealing plate 304 on the top cover 303 leaves the pickling tank 1. When it is necessary to remove the workpiece, the top cover 303 can be pulled to slide inside the guide bracket 305, thus facilitating the operation of the workpiece. To facilitate workpiece installation, a ring can be set at the bottom of the workpiece mounting plate 402. The workpiece is hung on the ring via a hook. Under the action of the gas spill prevention component 3, the workpiece can be moved to directly above the pickling tank 1. Under the action of the lifting screw 302, the workpiece reaches the inside of the pickling tank 1. At this time, the lifting cylinder 401 can be activated, which pushes the connecting bracket 403 downward. The connecting bracket 403 then drives the guide sleeve 405 and the workpiece mounting plate 402 to descend simultaneously, thereby causing the telescopic plate 404 on the guide sleeve 405 to move downward until the baffle plate 205 reaches the support plate 204. Above, the baffle plate 205 blocks all air inlets 203. At this time, the workpiece is also immersed in the pickling solution. During the pickling process, when it is necessary to change the immersion depth of the workpiece, the lifting cylinder 401 can push the connecting bracket 403 to continue moving downward. At this time, the workpiece continues to be immersed, while the guide sleeve 405 slides outside the telescopic plate 404. It should be noted that when the guide sleeve 405 and the telescopic plate 404 cannot be separated from each other, and the connecting bracket 403 is in the highest position, the baffle plate 205 is located at the air inlet 203. The air inlet 203 cannot be blocked from above, which facilitates gas collection. When the vacuum pump is started, the vacuum pump can draw the gas from the air inlet 203 into the interior of the connecting pipe 202, and then through the connecting pipe 202 to the interior of the collection chamber 201. When gas treatment is not required, the air inlet 203 can be blocked by the baffle plate 205. The baffle plate 205 and the air inlet 203 are in close contact to prevent hydrochloric acid and other substances from entering the air inlet 203. A support plate 204 is provided at the bottom of the baffle plate 205 to support the baffle plate 205.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
