Description

Technical Field

[0001] This utility model relates to the field of production degassing technology, and in particular to a degassing device for the production of carboxylated butadiene nitrile latex. Background Technology

[0002] Carboxylated nitrile butadiene latex is an anionic polymer emulsion prepared by emulsion copolymerization of butadiene, acrylonitrile, and a carboxyl-containing third monomer. Its molecular chain has carboxyl side groups, making it a terpolymer latex. During the production of carboxylated nitrile butadiene latex, degassing is required. Chinese Patent Publication No. CN221618651U discloses a degassing device for the production of carboxylated nitrile butadiene latex. This degassing device uses a rotating rod to drive a stirring rod, which causes a first scraper to scrape off the raw material adhering to the walls of the inner cavity of the degassing chamber. The rotating rod also drives a second stabilizing rod, which causes a second scraper to scrape off the raw material adhering to the bottom wall of the inner cavity of the degassing chamber. This improves the completeness of material feeding. Liquid is injected into the annular pipe through a water inlet pipe and sprayed out through a nozzle, which improves the cleaning quality and makes the cleaning effect more complete, avoiding incomplete cleaning. However, the above-mentioned patent has certain drawbacks. It is not convenient to maintain and replace the scraper. After long-term use, as the scraper wears down, gaps will appear between it and the inner wall of the box, requiring frequent manual adjustments. Therefore, it is not practical enough. Therefore, we propose a degassing device for the production of carboxylated nitrile latex. Utility Model Content

[0026] Example 1 like Figure 1-4As shown, this utility model provides a technical solution: a degassing device for producing carboxylated nitrile butadiene latex, including a housing 1, a cleaning mechanism 2 installed inside the housing 1, an inlet 101 opened at the top of the housing 1 near the left side for feeding carboxylated nitrile butadiene latex into the housing 1, a stirring assembly 102 installed at the top of the housing 1 extending into the interior, a degassing pump 103 installed at the top of the housing 1 near the back, and an outlet 104 opened at the bottom of the housing 1. The end cleaning auxiliary component 105 is provided. A sealing door 106 is rotatably connected to the front of the housing 1. A sealing strip is adhered to the outer periphery of the sealing door 106 at the contact point with the housing 1. The cleaning mechanism 2 includes a card seat 201. A pushing component 202 is installed inside the card seat 201. A connecting plate 203 is inserted inside the card seat 201 and outside the pushing component 202. A scraper 204 is fixedly connected to the outer side of the connecting plate 203. A fixing component 205 is installed near the outer periphery of the card seat 201.

[0027] Example 2 like Figure 1-4As shown, a sealing cap 1011 is threadedly connected to the outer periphery of the feed inlet 101, and an electric valve 1041 is installed inside the discharge outlet 104. The sealing cap 1011 can seal the feed inlet 101, and the electric valve 1041 can control the opening and closing of the discharge outlet 104, improving ease of use. The stirring assembly 102 includes a motor 1021, which is fixedly connected to the housing 1. The output end of the motor 1021 extends into the housing 1 and is fixedly connected to a stirring frame 1022. The rotation of the motor 1021 can drive the stirring frame 1022 to rotate, thereby gradually discharging the gas in the carboxylated nitrile latex in the housing 1, which is then extracted by the degassing pump 103. The cleaning auxiliary assembly 105 includes an annular pipe 1051. The annular pipe 1051 is fixedly connected to the housing 1. Several outlets 1052 are equidistantly arranged around the bottom of the annular pipe 1051. An inlet pipe 1053 is connected to the top of the annular pipe 1051 near the right side, allowing water to enter the annular pipe 1051 and flow out through the outlets 1052. This facilitates wetting the inner wall of the housing 1 during cleaning, improving cleaning efficiency. The mounting base 201 is made of U-shaped stainless steel, with its inner end welded to the mixing rack 1022. Stainless steel has strong corrosion resistance, which can improve the service life of the mounting base 201. The pushing component 202 includes a sliding rod 2021, which is slidably connected to the mounting base 201. A push plate 202 is welded to one end of the sliding rod 2021 extending to the inner side of the mounting base 201. 2. A spring 2023 is sleeved inside the slide rod 2021 and between the push plate 2022 and the card seat 201. The spring 2023 can continuously push the push plate 2022 outward, thereby causing the push plate 2022 to push the connecting plate 203 and the scraper 204, ensuring the cleaning effect of the scraper 204 on the inner wall of the box 1. The connecting plate 203 has several grooves 2031 evenly spaced from top to bottom inside. The grooves 2031 allow the connecting plate 203 to slide back and forth around the threaded rod 2054 and the insert rod 2053, facilitating the pushing operation of the pushing component 202. The fixing component 205 includes a first fixing strip 2051 and a second fixing strip 2052, which are respectively set in the card seat 201. On both sides, an insert rod 2053 is welded to the inner side of the first fixing strip 2051, passing through the slide groove 2031 near the middle and the retaining seat 201. The insert rod 2053 is inserted into the second fixing strip 2052. A threaded rod 2054 is threadedly connected to the outer side of the first fixing strip 2051 near the top and bottom, passing through the retaining seat 201 and the slide groove 2031 near the top and bottom. The threaded rod 2054 is threadedly connected to the second fixing strip 2052. The insert rod 2053 can pass through the slide groove 2031 and the retaining seat 201 and be inserted into the second fixing strip 2052, thereby limiting and fixing the connecting plate 203. By rotating the threaded rod 2054, the first fixing strip 2051 and the second fixing strip 2052 can be fixed together to prevent loosening during use.Improve ease of use.

[0028] The working process of this utility model is as follows: When cleaning a degassing device for producing carboxylated nitrile butadiene latex, water first enters the annular pipe 1051 through the inlet pipe 1053 and flows out through the outlet 1052, wetting the inner wall of the tank 1. The motor 1021 drives the stirring frame 1022 to rotate, which in turn drives the cleaning mechanism 2 to rotate inside the tank 1. This causes the scraper 204 to scrape off the residual carboxylated nitrile butadiene latex on the inner wall of the tank 1. Finally, the scraped carboxylated nitrile butadiene latex mixed with water is discharged through the outlet 104, completing the entire cleaning process. After long-term use, when the scraper 204 wears down... When the spring 2023 continuously pushes the push plate 2022 outward, the push plate 2022 pushes the connecting plate 203 outward, thus keeping the worn hanging strip in contact with the inner wall of the box 1. When the scraper 204 needs to be replaced, the sealing door 106 is opened, and the threaded rod 2054 is rotated through the sealing door 106 to disengage it from the second fixing strip 2052, the card seat 201 and the connecting plate 203. The connecting plate 203 and the scraper 204 can then be removed from the card seat 201. This greatly reduces the number of manual maintenance operations, improves the cleaning effect and effectively enhances practicality.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
