[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0017] like Figure 1 As shown, a solid-state organotin heat stabilizer production device includes a frame 1, a mixing kettle 2, and a blending and stirring device. The frame 1 has a corresponding supporting force. The mixing kettle 2 is mounted on the frame 1 and defines an internal receiving chamber with an open upper end. The blending and stirring device is disposed within the mixing kettle 2 and has a first stirring direction and a second stirring direction. The first stirring direction and the second stirring direction have a predetermined angle (the stirring method is normal rotational stirring, and the central axis of the first stirring direction and the central axis of the second stirring direction have a predetermined angle).

[0018] The blending and stirring device includes a first mixing unit and a second mixing unit respectively arranged at the bottom and side of the receiving chamber in the mixing kettle 2; the first mixing unit performs mixing operations in a first stirring direction at the lower part of the receiving chamber, and the second mixing unit performs mixing operations in a second stirring direction on the side of the receiving chamber. After the powder raw materials and liquid additives are fed, the materials are mixed by low-speed stirring in the first direction, and the mixed materials are sheared and crushed by rapid stirring in the second direction and then mixed for the second time.

[0019] Specifically, the first mixing unit includes a stirring blade 5, which is connected to a corresponding transmission unit 6. The transmission unit 6 provides a rotational driving force to the stirring blade 5. The transmission unit 6 includes a reducer 7, which enables the stirring blade 5 to stir at a low speed. The transmission unit 6 can be a belt drive and can be configured on the frame 1. The reducer 7 enables the stirring blade 5 to stir at a low speed to mix the powder and water. The stirring blade 5 is symmetrically distributed and has a predetermined operating length. The second mixing unit includes a cutting blade 8, which is connected to a corresponding cutting motor 10. The cutting motor 10 provides a rotational driving force to the cutting blade 8. The cutting motor 10 and the cutting motor 10 can also be configured at corresponding positions on the frame 1. The delivery end of the cutting motor 10 is connected to the rotating shaft 9. The cutting blade 8 is configured on the rotating shaft 9. After the cutting motor 10 is started, the output end of the cutting motor 10 rotates to drive the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the cutting blade 8 to rotate, thereby shearing and crushing the mixed material. Multiple groups of cutting blades 8 can be provided, and each group of cutting blades 8 is arranged in an array along the central axis direction of the rotating shaft 9. The multiple groups of cutting blades 8 are staggered and shear and crush on the circumferential path in the first stirring direction, so that the agglomerated materials are crushed and mixed again.

[0020] Specifically, in terms of the method of feeding materials into the mixing kettle 2, the top of the mixing kettle 2 is open and is equipped with an upper cover 3. The upper cover 3 is connected to a vent and is fixed in position by a door cover. The specific material, structure, and how to open and close the upper cover 3 are existing technologies and will not be repeated here. A feed hopper 4 is arranged on the upper cover 3, and a control valve is arranged at the discharge point of the feed hopper 4. The material body can be delivered to the feed hopper 4 by spiral feeding.

[0021] Furthermore, mixing vessel 2 can be connected to an external spray device to deliver a liquid additive into mixing vessel 2 by spraying. The specific spray device primarily comprises a liquid container, an air duct, an atomizing nozzle, and a control valve. The specific connection and installation methods are known in the art and will not be elaborated on in detail. The liquid additive is delivered into mixing vessel 2 by spraying and blended with the material. The stirring blade 5 stirs the mixture at a low speed.

[0022] Regarding the discharge method of the mixing kettle 2, a discharge port can be provided at the bottom or side of the mixing kettle 2, and a corresponding pushing device can be configured to discharge the material. Reference can be made to the existing technology and will not be described in detail here. After discharge, the material can be sent to subsequent processing equipment for corresponding processing and storage operations.

[0023] The specific usage is as follows: install the device at a suitable working position, feed the powder raw material through the feed hopper 4, atomize the liquid additive through the atomizing device and feed it into the mixing kettle 2; start the transmission unit 6 and the cutting motor 10, and the stirring blade 5 arranged inside the accommodating chamber rotates at a low speed for stirring, and the cutting knife 8 located on the side rotates to shear and crush the agglomerated mixed material body to mix the mixed material body; after the mixing is completed, open the discharge port and discharge the material.

[0024] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents. In short, if those skilled in the art are inspired by this, and without departing from the purpose of the invention of the present invention, they can design structural methods and embodiments similar to the technical solution without creativity, and they should all fall within the scope of protection of the present invention.
