Description

Technical Field

[0001] This utility model relates to the field of acrylic emulsion processing technology, and in particular to a uniform feeding device for acrylic emulsion polymerization. Background Technology

[0002] Acrylic emulsion is a milky white or nearly transparent viscous liquid. It is an emulsion copolymerized from pure acrylate monomers. It is a small-particle-size, multi-purpose, and high-performance emulsion suitable for various coating formulations. It has outstanding water resistance and weather resistance, especially in high-gloss and semi-gloss coatings. Acrylic emulsion has good water resistance, alkali resistance, and stain resistance, and good adhesion to brick, wood, and steel surfaces. It can be used to formulate not only matte, semi-gloss, and high-gloss latex paints, but also high-quality coatings for floors, cement tiles, and tennis courts. When polymerizing acrylic emulsion, users need to add it at a uniform rate, and a feeding device is required.

[0003] A search revealed that Chinese patent CN204298297U discloses a uniform feeding device for acrylate emulsion polymerization, comprising a nitrogen source device, a buffer tank, and a feeding tank connected in sequence. The nitrogen source device is equipped with a nitrogen pressure reducer, the buffer tank is equipped with a small-range pressure gauge, and an inlet valve is installed on the outlet pipe of the buffer tank. The feeding tank is equipped with a pressure gauge and a level gauge, and a feeding valve is installed on the outlet pipe of the feeding tank. This invention, by using a buffer tank to continuously apply a fixed pressure to the liquid surface of the feeding tank, can control the material to maintain a relatively uniform feeding rate into the polymerization reactor throughout the polymerization process, increasing control stability, which is beneficial to improving product quality, and simplifies the operation process without consuming energy.

[0004] The aforementioned patent has the following shortcomings: its function is not perfect when the user is using the acrylic emulsion to add it at a uniform rate, and it is not convenient enough when the user needs to adjust the output of the feeding device.

[0005] Therefore, we provide a uniform feeding device for acrylate emulsion polymerization. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Example 1: As Figures 1-5 As shown, a uniform feeding device for acrylic emulsion polymerization includes a feeding device body 1, a limiting block 6 fixedly connected to the upper surface of the feeding device body 1, a limiting insertion plate 19 being inserted into the inner ring surface of the limiting block 6, and a connecting base plate assembly 17 being fixedly connected to the side surface of the limiting insertion plate 19.

[0036] First, the inner surface of the limiting block 6 has a first hollow opening 7, and the size of the first hollow opening 7 and the I-shaped limiting rod 9 are matched. The first hollow opening 7, which is matched with the size of the I-shaped limiting rod 9, can facilitate the user to use the I-shaped limiting rod 9 for limiting. The bottom surface of the feeding device body 1 is fitted with anti-slip fixing feet 20, and there are multiple anti-slip fixing feet 20 that are parallel to each other. The multiple anti-slip fixing feet 20 that are parallel to each other can facilitate the user to place the feeding device body 1 in an anti-slip manner.

[0037] Example 2: Figures 1-5 As shown, a uniform feeding device for acrylic emulsion polymerization has a main output pipe 5 installed on the side surface of the connecting base plate assembly 17, an output pipe 2 installed on the side surface of the main output pipe 5, a shock-absorbing spring 15 fixedly connected to the inner surface of the limiting plug plate 19, a snap-fit ​​block 14 limited and inserted into the inner ring surface of the limiting plug plate 19, a protective shell 8 limited and snapped into the inner ring surface of the connecting base plate assembly 17, a connecting block 11 fixedly connected to the inner surface of the protective shell 8, a motor 18 fixedly connected to the side surface of the connecting block 11, a spiral output rod 12 fixedly sleeved at the top of the output shaft of the motor 18, and a controller 10 welded to the side surface of the connecting base plate assembly 17.

[0038] First, a limiting opening 16 is formed on the side surface of the limiting block 6, and the limiting opening 16 and the snap-fit ​​block 14 are matched in size. The limiting opening 16, which matches the size of the snap-fit ​​block 14, allows the user to limit the use of the snap-fit ​​block 14. A cylindrical limiting rod 13 is fixedly connected to the side surface of the snap-fit ​​block 14, and the cylindrical limiting rod 13 is connected to the limiting plug plate 19. The cylindrical limiting rod 13, which is connected to the limiting plug plate 19, allows the user to limit the use of the snap-fit ​​block 14. A mounting flange 3 is installed on the side surface of the output pipe 2, and the mounting flange 3 is connected to the main output pipe 5 through the output pipe 2. The mounting flange 3, which connects the output pipe 2 and the main output pipe 5, allows the user to easily install the mounting flange 3 with bolts. The side surface of the mounting flange 3 has a mounting opening 4, which is centered around the mounting flange 3. The mounting opening 4, which is centered around the mounting flange 3, allows the user to easily insert and limit the bolts. The motor 18 is connected to the protective shell 8 through the snap-fit ​​block 14, which is symmetrically arranged vertically with the horizontal axis of the motor 18 as the axis of symmetry. This symmetrical arrangement allows the user to stably install the motor 18 onto the protective shell 8.

[0039] Based on the above structure, when the user needs to output acrylic emulsion, the user needs to install the acrylic emulsion output device on the mounting flange 3 with bolts. Then, the user needs to turn on the motor 18. After the motor 18 starts, it can drive the spiral output rod 12 to rotate. Through the output pipe 2, which limits the spiral output rod 12, the user can feed the acrylic emulsion at a uniform speed through the output pipe 2. After the user presses the locking block 14, the user can adjust it up and down on the limiting block 6. After the user adjusts it, the locking block 14 is reset by the damping spring 15. The user can then insert the locking block 14 into the limiting openings 16 at different heights. Therefore, the user can efficiently adjust the feeding device up and down.
