It cannot be guaranteed that the raw materials inside the reaction vessel can be mixed under uniform heating. Utility Model Content

[0005] In view of the above situation and to overcome the shortcomings of the prior art, this utility model provides a polycarboxylic acid synthesis device that can better mix raw materials and help the raw materials to be heated more evenly.

[0006] The technical solution adopted by this utility model is as follows: This utility model provides a polycarboxylate synthesis device, including a synthesis reaction tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0023] like Figures 1-6 As shown, this utility model discloses a polycarboxylate synthesis device, including a synthesis reaction tank 1, with support legs 9 for supporting it, a feed pipe 10 at the top of the synthesis reaction tank 1, and a discharge pipe 11 at the bottom of the synthesis reaction tank 1. It also includes a drive shaft 2, a stirring assembly 3, a lifting cylinder 4, heating spiral blades 5, and lifting spiral blades 6. The synthesis reaction tank 1 is divided into a premixing chamber 7 and a heating mixing chamber 8 from top to bottom, connected by a discharge pipe 12. The feed pipe 10 is connected to the premixing chamber 7, and the discharge pipe 11 is connected to the heating mixing chamber 8. A first solenoid valve 20 is installed on the discharge pipe 11; a second solenoid valve 21 is installed on the discharge pipe 12; a temperature sensor 22 is installed in the heating mixing chamber 8; a motor 19 is installed at the top of the synthesis reaction tank 1, and the drive shaft 2 is located on the output shaft of the motor 19.

[0024] The lifting cylinder 4 is located on the top wall of the heating mixing chamber 8. The upper part of the lifting cylinder 4 is provided with a discharge port 16, and the bottom of the lifting cylinder 4 is provided with an opening 17. The heating spiral blade 5 is fixed on the inner wall of the heating mixing chamber 8 and sleeved on the outside of the lifting cylinder 4. The heating spiral blade 5 is provided with a spiral cavity, and an electric heating wire 18 is provided in the spiral cavity. The drive shaft 2 is rotatably located on the top of the synthesis reaction tank 1 through a bearing. The drive shaft 2 rotates downward and passes through the premixing chamber 7 and the lifting cylinder 4 in sequence, and extends from the center of the opening 17 to the bottom of the heating mixing chamber 8. The stirring assembly 3 is located on the drive shaft 2 and inside the premixing chamber 7. The heating spiral blade 5 is sleeved on the drive shaft 2 for lifting the material.

[0025] The stirring assembly 3 includes an anchor blade 13, a connecting rod 14, and a screw ribbon 15. The connecting rod 14 is mounted on the drive shaft 2, the screw ribbon 15 is mounted on the connecting rod 14, and the anchor blade 13 is mounted on the drive shaft 2 and located below the screw ribbon 15.

[0026] In practical use, the material is added to the premixing chamber 7 through the feed pipe 10. The electric heating wire 18 and motor 19 are then activated. The motor 19 drives the anchor blades 13 and the screw ribbon 15 to rotate, mixing the material radially and axially respectively, resulting in better mixing. After the material is premixed, the second solenoid valve 21 is opened, allowing the material in the premixing chamber 7 to fall onto the heating spiral blades 5 and flow downwards along them. During this flow, the electric heating wire 18 heats the material. When the material reaches the bottom of the heating mixing chamber 8, the lifting spiral blades 6 lift it, allowing it to fall back onto the heating spiral blades 5 through the outlet 16, thus circulating and heating the material. Furthermore, the lifting spiral blades 6 further mix and stir the material during this lifting process, resulting in more uniform mixing. This structure not only ensures more uniform heating but also more even mixing, thereby improving product quality. The temperature of the material is monitored by the temperature sensor 22.

[0027] In summary, this solution can premix and stir the materials using the stirring assembly 3, and the combination of the anchor blade 13 and the connecting rod 14 can simultaneously stir the materials from both the axial and radial directions, improving the stirring effect. This solution can also lift the materials using the lifting spiral blade 6, which can further mix the materials. The materials at the bottom of the heated mixing chamber 8 are lifted to the upper part of the lifting cylinder 4 and flow out from the discharge port 16, and then flow along the heating spiral blade 5. During the process of the materials flowing along the heating spiral blade 5, the materials are heated by the electric heating wire 18, which makes the materials more evenly heated.
