Description

Technical Field

[0001] This utility model relates to a hazardous chemical dosing device, belonging to the field of surface treatment technology. Background Technology

[0002] Surface treatment often requires the addition of various strong acids, strong alkalis and other hazardous chemicals. If these hazardous chemicals are poured directly into the plating tank or large beaker, they are likely to splash out and even onto the human body. Furthermore, concentrated hydrochloric acid and concentrated nitric acid are highly volatile. If not properly protected when adding these chemicals, they can corrode the human skin, posing a very high safety risk.

[0003] Traditional methods primarily utilize diversion rods to guide hazardous chemicals into the plating tank. Specifically, the operator holds a bottle containing the highly corrosive liquid close to the diversion rod, then slowly pours the liquid into the rod, diverting it into the plating tank. However, the highly corrosive liquid releases heat upon contact with the plating solution, increasing its evaporation rate. In such cases, only enhanced personal protective equipment can address the issue, and the safety risk remains high.

[0004] In addition, existing systems or equipment can automate the dosing of hazardous chemicals. For example, Chinese patent document CN205035070U discloses an online chemical dosing system that can solve all the aforementioned safety issues. However, this system is expensive to purchase, and some manufacturers do not have the economic or site conditions to install it, so they still use traditional methods for hazardous chemical dosing. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hazardous chemical dosing device.

[0006] This utility model is achieved through the following technical solution: A hazardous chemical dosing device includes a conduit, a fixing frame, and several fixing seats. One end of the conduit is provided with a funnel, several fixing seats are provided in the middle of the conduit, and the fixing frame is provided on the conduit near the funnel.

[0007] The catheter is Z-shaped.

[0008] The conduit is arranged horizontally in the middle, with one end having a funnel arranged vertically upwards and the other end arranged vertically downwards.

[0009] The conduit has two fixing seats in the middle, and the bottom surfaces of the two fixing seats are coplanar.

[0010] The fixing seat is rectangular in shape, and the top of the fixing seat has a semi-circular groove whose shape and size are adapted to the shape and size of the conduit.

[0011] The fixing frame includes multiple rings and multiple support rods. The multiple rings are arranged coaxially and fitted onto the guide tube. The multiple support rods are arranged along the axial direction of the rings and are arranged in a circumferential array relative to the rings. The multiple support rods are connected to all the rings respectively.

[0012] The lower end face of the support rod is coplanar with the bottom surface of the fixed base.

[0013] The beneficial effects of this invention are as follows: The conduit increases the distance between the operator and the plating tank, keeping the contact point between the plating solution and hazardous chemicals away from the human body, thus reducing the safety risks associated with adding hazardous chemicals. Simultaneously, before adding hazardous chemicals, the plating tank can be covered with a lid, leaving only a small opening, which reduces the risk of hazardous chemicals splashing onto the operator during the dosing process and also helps reduce the amount of corrosive gases volatilized into the air. Furthermore, during dosing, the hazardous chemicals flow downwards along the tank wall and come into contact with the plating solution, further reducing the amount of corrosive gases volatilized during the dosing process, thereby lowering the safety risks associated with adding hazardous chemicals.

[0016] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0017] like Figure 1As shown, the present invention provides a hazardous chemical dosing device, comprising a conduit 1, a fixing frame 3, and multiple fixing seats 2. One end of the conduit 1 is provided with a funnel 4, the multiple fixing seats 2 are located in the middle of the conduit 1, and the fixing frame 3 is located on the conduit 1 near the funnel 4. The device is placed beside the plating tank where the hazardous chemical needs to be added, or directly on the plating tank cover. With the support and fixation of the fixing frame 3 and the multiple fixing seats 2, the conduit 1 can be stably placed beside the plating tank or on the plating tank cover. Then, the device is moved so that the end of the conduit 1 furthest from the funnel 4 is as close as possible to the plating tank wall. Next, the plating tank cover is closed, and the hazardous chemical to be added is slowly poured into the funnel 4. The hazardous chemical then flows along the conduit 1 into the plating tank and flows down the tank wall towards the bottom. The conduit 1 increases the distance between the operator and the plating tank, keeping the contact point between the plating solution and the hazardous chemicals away from the operator's body and reducing the safety risks associated with adding hazardous chemicals. Simultaneously, before adding hazardous chemicals, the plating tank can be covered with a lid, leaving only a small opening. This reduces the risk of hazardous chemicals splashing onto the operator during addition and also helps reduce the amount of corrosive gases volatilized into the air. Furthermore, during addition, the hazardous chemicals flow downwards along the tank wall and come into contact with the plating solution, further reducing the amount of corrosive gases volatilized during the addition process, thus lowering the safety risks associated with adding hazardous chemicals. The device has advantages such as simple structure and low manufacturing cost.

[0018] Specifically, the conduit 1 and funnel 4 are made of highly corrosion-resistant materials such as polyethylene, while the fixing seat 2 and fixing bracket 3 are made of stainless steel.

[0019] The catheter 1 is zig-shaped.

[0020] The middle part of the conduit 1 is arranged horizontally, and one end with the funnel 4 is arranged vertically upward and the other end is arranged vertically downward.

[0021] The conduit 1 has two fixing seats 2 in the middle, and the bottom surfaces of the two fixing seats 2 are coplanar.

[0022] The fixing seat 2 is rectangular, and its top has a semi-circular groove whose shape and size are adapted to the shape and size of the conduit. Figure 1 As shown, after inserting the middle horizontal section of the conduit 1 into the semi-circular groove on the fixing seat 2, the conduit 1 and the fixing seat 2 are bonded and fixed with glue.

[0023] The fixing frame 3 includes multiple rings 31 and multiple support rods 32. The multiple rings 31 are arranged coaxially and fitted onto the conduit 1. The multiple support rods 32 are arranged along the axial direction of the rings 31 and in a circumferential array relative to the rings 31. Each support rod 32 is connected to all the rings 31. In use, the rings 31 are fitted with the conduit 1 with a small gap, and the rings 31 are glued to the conduit 1 for fixation.

[0024] The lower end face of the support rod 32 is coplanar with the bottom face of the fixed base 2.
