[0002] Chromic acid mist is liquid droplets formed by chromic acid volatilizing in the air, which is commonly found in the air around the electroplating tank during electroplating operations. If the concentration of chromic acid mist is too high, nasal septum perforation may occur after a few months of exposure. It can also cause pharyngitis, pneumonia and allergic asthma.

[0003] At present, during electroplating operations, a float filler is generally covered on the surface of the electroplating liquid to prevent the volatilization of chromic acid mist. The existing float is generally hollow in design, and the float is easily corroded by the chromic acid mist. After corrosion, the float is filled with electroplating liquid, and the float will sink to the bottom of the electroplating liquid, which will not achieve the effect of preventing the volatilization of chromic acid mist. In addition, the existing float is generally made of PE material, which is relatively soft and easy to bend. When using the float, it is easy to cause the float to sink, thereby reducing the service life of the float. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] This embodiment relates to a corrosion-resistant multi-cavity polyvinyl chloride (PVC) float, the overall structure of which is as follows: Figure 1 As shown, it includes a housing 1 , a partition 2 , and a sealing member 4 .

[0032] There are two shells 1 arranged opposite to each other, and a partition 2 fixedly arranged inside the shell 1 , the partition 2 divides the shell 1 into different chambers 3 , the two shells 1 are buckled together, and a seal 4 is arranged between the two shells 1 .

[0033] It is worth mentioning that the purpose of setting up two shells 1 is to facilitate mold opening and assembly. The partition 2 divides the shell 1 into different chambers 3. The partition 2 and the inner wall of the shell 1 are integrally formed. The partitions 2 of the two shells 1 abut against each other to ensure that each chamber 3 is a separate chamber. When the plating liquid corrodes into one or several chambers 3, the float can still float on the liquid surface. The seal 4 can improve the sealing of the two shells 1 after assembly to prevent the plating liquid from entering the float from the joint of the two shells 1. The two shells 1 can be connected by snap-fitting or hot-melt together, depending on the actual situation.

[0034] Based on the above overall introduction, an exemplary structure of the corrosion-resistant multi-cavity polyvinyl chloride (PVC) float of this embodiment is as follows: Figure 1 and Figure 2 As shown, the housing 1 is hemispherical, and two housings 1 are buckled together to form a sphere. The contact surface of the two housings 1 after buckling together is a connecting surface 5, and the sealing member 4 includes a strip gasket 401 and an annular gasket 402.

[0035] It should be noted that the shell 1 adopts a hemispherical setting, which can ensure that the two shells 1 are spherical after assembly, and the spherical float can contact the liquid surface at any position, so as to facilitate the rolling of the float on the liquid surface, realize the contact between any surface of the float and the liquid surface, and improve the service life of the float. The connecting surface 5 of the two shells 1 is a horizontal plane, which can increase the contact area after the two shells 1 are buckled together, and the purpose of the sealing member being divided into a strip gasket 401 and an annular gasket 402 is to ensure that the partition 2 and the shell 1 can be sealed to prevent the plating solution from flowing from the connection between the two partitions 2.

[0036] As a preferred example, Figure 2 and Figure 3 As shown, the connecting surfaces 5 of the two shells 1 of this embodiment are respectively provided with an annular groove 6 and an annular strip 7, the annular strip 7 is inserted in the annular groove 6, and the annular pad 402 is arranged between the annular groove 6 and the annular pad 402. The partitions 2 of the two shells 1 are respectively provided with a groove 8 and a convex strip 9, the convex strip 9 is inserted in the groove 8, and the strip pad 401 is arranged between the groove 8 and the convex strip 9.

[0037] Specifically, the annular groove 6 and the annular strip 7 are engaged with each other, which not only facilitates the buckling of the two shells 1, but also improves the sealing. Combined with the setting of the annular gasket 402, it can prevent the plating liquid from flowing into the float from the buckling point of the two shells 1. The annular gasket 402 is located in the annular groove 6, and the annular strip 7 and the annular groove 6 abut against each other on the seal to achieve a sealing effect. Similarly, the groove 8 and the convex strip 9 are engaged with each other, and the convex strip 9 and the groove 8 abut against each other on the seal to improve the sealing effect and facilitate the buckling of the two shells 1.

[0038] As a preferred embodiment, Figure 2 and Figure 3 As shown, one of the partitions 2 in this embodiment is higher than the adjacent connection surface 55-10MM, and the other partition 2 is lower than the adjacent connection surface 55-10MM. It should be noted that the purpose of the partitions 2 of the two shells 1 not being level with the connection surface 5 is to improve the sealing between the partitions 2 and the shells 1, and to improve the buckling strength of the two shells 1 to avoid separation of the two shells 1, and the purpose of being higher than 5-10MM or lower than 5-10MM is to ensure that after the two shells 1 can be buckled, the partitions 2 can also bite each other, so that each cavity is an independent cavity.

[0039] As a preferred embodiment, Figure 2 and Figure 3 As shown, the partition 2 of this embodiment is a cross-shaped plate, which divides the shell 1 into four chambers 3, and the partition 2 divides the shell 1 into at least two chambers 3. The buckle connection between the two shells 1 is an interference fit, the shell 1 and the partition 2 are made of polyvinyl chloride (PVC), and the seal is made of EPDM.

[0040] It should be noted that the purpose of using polyvinyl chloride (PVC) material for the shell 1 and the partition 2 is that polyvinyl chloride (PVC) is harder and more durable, not easy to deform during use, and the service life of the float is increased, and the floating effect can also be achieved. In the existing electroplating industry and chemical industry, the use of PVC material in contact with corrosive liquids is still in a blank period. After one chamber 3 of the float of this embodiment is filled with electroplating liquid, the buoyancy of other chambers 3 can still achieve the floating effect and avoid the volatilization of chromic acid mist. Of course, the shell 1 and the partition 2 can also be made of other materials with corrosion resistance, and the purpose of using EPDM material for the seal is that EPDM has aging resistance and chemical resistance. Chemical corrosion can also achieve a sealing effect and improve the sealing between the two shells 1. The interference fit of the two shells 1 can avoid the separation of the two shells 1 and improve the clamping force of the two shells 1. The staggered arrangement of the partition 2 and the shell 1 wall further improves the clamping force of the two shells 1. The partition 2 is arranged in a cross shape to ensure that the interior of the shell 1 is divided into four chambers 3. After the float contacts the liquid surface, at most two chambers 3 are corroded and filled with liquid, and the other two chambers 3 can still achieve the floating effect. Of course, according to the situation, the float can also be divided into two chambers 3, three chambers 3 or five chambers 3 or more chambers 3. It is only necessary to make a mold according to the actual situation.

[0041] The corrosion-resistant multi-cavity polyvinyl chloride (PVC) float in this embodiment ensures that leakage occurs in a certain cavity through the setting of different chambers 3, and other cavities can also float on the liquid level surface to avoid sinking. The setting of the seal improves the sealing of the connection between the two shells 1. The matching setting of the annular groove 6 and the annular strip 7 ensures that the two shells 1 are in a bite arrangement, which can also improve the sealing of the two shells 1. The partitions 2 and the walls of the two shells 1 are staggered with each other, which can improve the snap-fit ​​force of the two shells 1 and also improve the sealing of the two shells 1.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
