Description

Technical Field

[0001] This utility model relates to the field of caustic soda processing technology, specifically to a dust collection device for caustic soda discharge outlet. Background Technology

[0002] Sodium hydroxide, also known as caustic soda, is a white, translucent, crystalline solid. Its aqueous solution has a bitter taste and a slippery feel. Caustic soda is extremely soluble in water, releasing a large amount of heat upon dissolution. It is also readily soluble in water, alcohol, ethanol, and glycerol. Sodium hydroxide is hygroscopic; solid alkalis are highly hygroscopic and will eventually dissolve completely in air. When discharging caustic soda, the material is discharged from the outlet, and a packaging bag is placed below the outlet to collect it. During this process, alkali dust is emitted from the outlet, necessitating its collection and treatment.

[0003] However, when caustic soda is fed, alkali dust is released into the air, and the large space required for collection makes the dust collection ineffective, resulting in serious pollution in the workshop. Summary of the Invention

[0004] The purpose of this invention is to provide a dust collection device for caustic soda discharge outlet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust collection device for caustic soda discharge outlet, comprising an installation ring and a protective component. The lower end of the installation ring has a dust suction chamber inside. The protective component for dust collection is located at the lower end of the installation ring and includes a transparent cover, a counterweight ring, a malleable metal rod, and a dustproof net. The lower end of the transparent cover is connected to the counterweight ring, and a malleable metal rod is installed inside the counterweight ring. The lower end of the counterweight ring is connected to the dustproof net.

[0006] Furthermore, a feed tube is installed at the middle of the lower end of the mounting ring, and a mounting hole is opened in the middle of the mounting ring.

[0007] Furthermore, a sealing sponge is installed on the inner wall of the mounting hole, and the mounting hole and the sealing sponge are fixedly connected.

[0008] Furthermore, the upper end of the mounting ring is equipped with a fixing component that is fixed at the discharge port, and two sets of fixing components are provided.

[0009] Furthermore, the fixing component includes a top plate and a limiting clamp, and the limiting clamps are installed on both sides of the top plate.

[0010] Furthermore, the fixing component also includes a fixing plate and fixing holes. The fixing plate is installed on the inner side of the limiting clamp, and the fixing plate has fixing holes on its surface.

[0013] This utility model provides a dust collection device for the caustic soda discharge port, which has the following beneficial effects: 1. This utility model uses a transparent cover to cover the alkali dust raised at the discharge port, allowing the dust suction chamber to better extract the alkali dust and prevent the alkali dust from spreading too quickly and causing poor dust extraction effect. The counterweight ring and the plastic metal rod provide support for the bottom of the transparent cover. The plastic metal rod can also adjust the style of the bottom of the transparent cover according to the environment of the discharge port. The dustproof net prevents external dust from coming into contact with caustic soda during suction, thus affecting the quality of caustic soda.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figure 1 and Figure 3As shown, a dust collection device for a caustic soda discharge port includes an mounting ring 1 and a protective assembly 3. The lower end of the mounting ring 1 has a dust collection chamber 2, and the middle of the mounting ring 1 has a mounting hole 5. A sealing sponge 6 is installed on the inner wall of the mounting hole 5. The sealing sponge 6 fills and seals the gaps in the mounting hole 5 when the mounting ring 1 is installed on the outside of discharge pipes of different sizes. The mounting hole 5 and the sealing sponge 6 are fixedly connected. A fixing assembly 7 for fixing the discharge port is installed on the upper end of the mounting ring 1. Two sets of fixing assemblies 7 are provided. The fixing assembly 7 includes a top plate 701 and a limiting clamp 702, and limiting clamps 702 are installed on both sides of the top plate 701. 2. The fixing component 7 also includes a fixing plate 703 and a fixing hole 704. The fixing plate 703 is installed on the inner side of the limiting clamp 702. The fixing plate 703 moves and adjusts its position on the top plate 701 according to the size of the discharge port. The limiting clamp 702 makes the fixing plate 703 move in a directional manner. The fixing plate 703 has a fixing hole 704 on its surface. The fixing hole 704 is used to connect the fixing plate 703 and the discharge pipe wall, and also to fix the fixing plate 703 and the top plate 701. The inner wall of the dust collection chamber 2 has a dust collection port 8. The dust collection chamber 2 and the dust collection port 8 are integrated structures. The side of the dust collection port 8 is connected to a dust collection pipe 9, and the end of the dust collection pipe 9 is connected to a dust collector 10.

[0019] like Figure 2 As shown, the protective component 3 for dust collection is located at the lower end of the mounting ring 1. The protective component 3 includes a transparent cover 301, a counterweight ring 302, a malleable metal rod 303, and a dustproof net 304. The lower end of the transparent cover 301 is connected to the counterweight ring 302. The transparent cover 301 covers the alkaline dust raised from the discharge port, allowing the dust collection chamber 2 to better extract the alkaline dust and prevent the alkaline dust from spreading too quickly, which would result in poor dust extraction. A malleable metal rod is installed inside the counterweight ring 302. 303, the counterweight ring 302 and the malleable metal rod 303 provide support for the bottom of the transparent cover 301. The malleable metal rod 303 can also adjust the bottom style of the transparent cover 301 according to the discharge port environment. The lower end of the counterweight ring 302 is connected to a dustproof net 304. The dustproof net 304 prevents external dust from contacting caustic soda during suction, which would affect the quality of caustic soda. The middle of the lower end of the mounting ring 1 is equipped with a feed pipe 4. The feed pipe 4 assists in the feeding of caustic soda and prevents small caustic soda particles from being directly sucked into the dust collection chamber 2.

[0020] In summary, the dust collection device at the caustic soda outlet is first based on... Figures 1-3The structure shown is used by fitting the mounting ring 1 onto the outside of the discharge pipe. Depending on the size of the discharge pipe, the fixing plate 703 is moved on the top plate 701. The limiting clamp 702 allows the fixing plate 703 to move in a specific direction. Then, screws are used to connect the fixing plate 703 to the discharge pipe wall, and the fixing plate 703 is fixed to the top plate 701. After the mounting ring 1 is installed, the sealing sponge 6 fills and seals the gap between the mounting hole 5 in the mounting ring 1 and the outer wall of the discharge pipe, preventing alkali dust from overflowing from the top. During feeding, the caustic soda collection bucket is positioned at the lower end of the feed pipe 4, allowing the caustic soda to fall and be collected more effectively, preventing small caustic soda particles from being directly sucked in. In the suction chamber 2, the transparent cover 301 covers the alkali dust raised from the discharge port. The dust collector 10 is turned on, creating a negative pressure inside the suction chamber 2 to suck up the alkali dust. With the transparent cover 301 limiting the area, the dust collection port 8 can better handle the alkali dust and prevent the alkali dust from spreading too quickly, which would result in poor dust extraction. During dust extraction, the counterweight ring 302 and the malleable metal rod 303 expand and support the bottom of the transparent cover 301. The malleable metal rod 303 can also be adjusted according to the discharge port environment, that is, the bottom style of the transparent cover 301 can be adjusted. During extraction, the dustproof net 304 prevents external dust from coming into contact with caustic soda during extraction, which would affect the quality of caustic soda.
