Description

Technical Field

[0001] The present application relates to the field of aluminum component detection, and in particular to a pickling fume hood. Background Art

[0002] After the existing aluminum rods are processed, the sampling personnel will conduct sampling inspections on the aluminum rods of the same production batch, and soak the aluminum rods in an alkaline solution. The alkaline solution reacts with the aluminum rods. After the reaction is sufficient, the aluminum rods are taken out for pickling. At this time, the fine cracks, mottled and other defects on the surface of the aluminum rods will be magnified and displayed, which is convenient for the sampling personnel to observe the surface defects of the test pieces. However, the existing aluminum rod testing equipment is relatively simple, mainly including a pool for loading alkaline solution and a container for placing the aluminum rods after immersion. The acidic liquid is loaded in a separate container. The aluminum rods are soaked in the alkaline solution to produce chemical reaction volatile gases, which cause the sampling personnel to absorb the gas. At the same time, the alkaline solution is corrosive to the human body. The experimenters usually wear laboratory gloves to reach into the alkaline solution to take the test items. This method will cause the experimenters to accidentally touch the alkaline solution. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0023] The present application embodiment discloses a pickling fume hood. Figure 1 , Figure 2 and Figure 3 , including a cabinet 1, a soaking pool 2 installed in the cabinet 1, a storage pool 3 installed in the soaking pool 2, a heating component 8 installed in the soaking pool 2, and a control component 4 installed in the cabinet 1 and used to control the storage pool 3 to move up and down. The soaking pool 2 is used to load an alkaline solution, and the storage pool 3 is located in the soaking pool 2. In order to facilitate the solution to enter the storage pool 3, a plurality of through holes 31 are opened on the storage pool 3. Through holes 31 are opened around and on the bottom of the storage pool 3 to facilitate the solution to enter the storage pool 3, so that the test piece can be fully immersed in the solution. When the test piece is immersed in the solution and fully reacts, in order to collect the gas generated by the reaction, an exhaust member 5 located above the soaking pool 2 is provided in the cabinet 1, and the exhaust end of the exhaust member 5 is connected to an exhaust pipe 12, which is used to guide the gas out of the laboratory to prevent the gas from polluting the indoor environment. The exhaust member 5 adopts a fan in the embodiment of the present application.

[0024] Reference Figure 2 and Figure 3 The immersion pool 2 includes a pool body 21 installed in the cabinet 1 and a pool cover 22 installed on the pool body 21. The pool body 21 and the pool cover 22 are hinged by a rotating shaft. A handle 7 is fixedly installed on the top surface of the pool cover 22 to facilitate opening the pool cover 22. The heating component 8 is used to speed up the reaction speed. The heating component 8 includes a plurality of heating rods 81. In order to improve the heating efficiency of the heating rod 81 on the solution in the immersion pool 2, a hollow interlayer 9 is provided on the side wall of the pool body 21, and a plurality of heating rods 81 are installed in the hollow interlayer 9 to improve the installation stability of the heating rod 81. In the embodiment of the present application, the hollow interlayer 9 is located at the lower end of the immersion pool 2. In order to place the parts to be tested, the horizontal plane of the solution placement amount is located below the immersion pool 2, and the top surface horizontal height of the hollow interlayer 9 is higher than the height of the solution placement horizontal plane.

[0025] Reference Figure 2 and Figure 3, when the items to be detected are fully soaked, it is necessary to take out the soaked items. The control component 4 drives the storage pool 3 to move upward, and the solution flows out of the storage pool 3 through the through hole 31. The control component 4 includes a control cylinder 41 installed in the cabinet 1 and located outside the soaking pool 2 and a connecting frame 42 fixedly installed on the piston end of the control cylinder 41. In the embodiment of the present application, four groups of control cylinders 41 are arranged, and the four groups of control cylinders 41 are located at the corners of the storage pool 3. One end of the connecting frame 42 is fixed to the piston end of the control cylinder 41, and the other end of the connecting frame 42 is fixed to the side wall of the storage pool 3. The top surface of the pool body 21 is provided with a through groove 6 for the connecting frame 42 to pass through. The through groove 6 is used to place the connecting frame 42 to prevent the connecting frame 42 from interfering with the opening and closing of the pool cover 22. After the control cylinder 41 drives the storage pool 3 to move upward, the liquid in the storage pool 3 also flows into the soaking pool 2. At this time, only the items to be detected that have fully reacted with the solution are left in the storage pool 3. The inspector can take out the parts to be inspected. In order to facilitate pickling, a cleaning pool 10 located on one side of the immersion pool 2 is provided in the cabinet 1. A water pipe and a water valve connected to the water pipe are installed on the cabinet 1 to facilitate subsequent inspectors to clean the parts to be inspected and observe surface defects of the items. Since an acidic solution is used for pickling, liquid will splash onto the clothes of the inspector during the cleaning process. A protective cover 11 for shielding the liquid is also installed on the cabinet 1. In the embodiment of the present application, the protective cover 11 is hinged by a rotating shaft. When in use, the protective cover 11 can be lifted toward the cleaning pool 10. When a large range of protection is required for the experimenter, the protective cover 11 can be a transparent partition, which is installed on the side of the cleaning pool 10 facing the outside, and a through hole 31 for the arm to pass through is also provided on the partition.

[0026] The implementation principle of a pickling fume hood in an embodiment of the present application is as follows: open the pool cover 22, place the object to be tested in the storage pool 3, and fully soak it in the alkaline solution. At this time, the exhaust part 5 is turned on to extract the gas generated by the reaction. After waiting for the soaking to be completed, open the pool cover 22, start the control cylinder 41 to drive the storage pool 3 to move up, and the storage pool 3 moves up. The solution in the storage pool 3 flows from the through hole 31 to the soaking pool 2, which is convenient for the inspector to take the soaked object to be tested and place it in the cleaning pool 10 for cleaning with the pickling solution. When cleaning, the inspector lifts the protective cover 11 to block the splashing liquid. The present application effectively reduces the possibility of gas contamination of the indoor environment during pickling and reduces the amount of alkaline solution contacted by the experimenter. At the same time, the control cylinder 41 is installed outside the soaking pool 2 to reduce the corrosion of the alkaline solution to it, which is convenient for the control cylinder 41 to operate normally.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
