Description

Technical Field

[0001] This invention belongs to the field of organotin compound processing technology, specifically relating to a solid organotin drying device. Background Technology

[0002] Organotin compounds are a class of organometallic chemicals containing at least one carbon-tin bond. Organotin compounds generally possess some degree of toxicity, especially the trisubstituted forms, which are more readily absorbed and distributed in the liver, kidneys, and brain. Tributyltin and triphenyltin are highly toxic to insects, bacteria, and algae, while trimethyltin and triethyltin are highly toxic to mammals. Drying solid organotin compounds is a crucial step after water washing and purification. Exposing the organotin reagent to room temperature allows its volatile solvents to evaporate naturally. This method is suitable for highly volatile solvents, but the drying rate is slow, thus requiring instruments to accelerate the drying process. Existing drying equipment cannot uniformly dry solid organotin compounds, nor can it achieve continuous drying.

[0003] In summary, existing technologies suffer from slow drying speeds and are unable to achieve continuous and uniform drying of solid organotin. Utility Model Content

[0021] The following is in conjunction with the appendix Figure 1-4 This utility model will be described in further detail below.

[0022] Example 1, refer to Figure 1-4 In this embodiment, to address the problem of slow drying speed and inability to continuously and uniformly dry solid organotin in existing technologies, this utility model discloses a solid organotin drying device, including a conveyor belt 7 with rotating structures 4 evenly distributed on it. Fixed rings 8 are located on both sides of the conveyor belt 7. An air pump 2 is connected to the fixed rings 8 via clamping columns 21. The rotating structures 4 and the bottom of a drying structure 5 are adapted to each other. The drying structure 5 is located on a support platform 3, with support columns 1 of equal height at each of the four corners of the support platform 3. The conveyor belt 7 is located inside the support platform 3. An air vent 17 is located above the drying structure 5 and is connected to a waste gas collection box. A solid organotin collection box is located at the outlet end of the conveyor belt 7. The air pump 2 is positioned at the midpoint of the line connecting two adjacent support columns 1, and the air pump 2 is connected to the clamping columns 21 via telescopic columns.

[0023] The conveyor belt 7 and the rotating structure 4 are designed to meet the needs of continuous drying of solid organotin. The rotating structure 4 and the drying structure 5 avoid uneven drying caused by continuous drying on one or multiple sides. The air pump 2 drives the clamping column 21 to move up and down, which in turn drives the conveyor belt 7 to move up and down to change the combination of the rotating structure 4 and the drying structure 5 to complete the drying operation. During the drying process, water will turn into gas and carry the waste gas through the vent 17 into the waste gas collection box to avoid environmental pollution. The air pump 2 and the clamping column 21 are connected by a telescopic column, so the lifting and lowering can be completed by two air pumps 2.

[0024] The rotating structure 4 is made of rubber and has a rotating column 13 inside. The top of the rotating column 13 is a turntable 14, which is adapted to the top of the rotating structure 4. The bottom of the rotating column 13 has a second helical gear 12, which is adapted to the first helical gear 11. The first helical gear 11 is connected to the motor 9 via a connecting shaft 10. The motor 9 is connected to the motor button 6, and the other side of the motor button 6 is on the outside of the rotating structure 4. The motor button 6 is a combination of a spring and a pressing element. One side of the spring is connected to the motor 9, and the other side is connected to the pressing element, which is the part of the motor button 6 on the outside of the rotating structure 4. The turntable 14 has raised and recessed blocks 15, which are fixed protrusions of varying sizes and heights. The drying structure 5 has protrusions 20 on its bottom, adapted to the motor button 6, in addition to the vents 17 on all four sides. Between the protrusions 20 and the vents 17 is a heating resistance wire 18, and between the heating resistance wire 18 and the turntable 14 is a buffer layer 19. The buffer layer 19 is made of graphite foam. A heating resistance wire 18 is installed on the top of the drying structure 5.

[0025] The rotating structure 4 is made of rubber, which facilitates small-range deformation and transport at the corner of the conveyor belt 7. The motor 9 drives the connecting shaft 10 to rotate the first helical gear 11, which in turn drives the second helical gear 12. The second helical gear 12 drives the turntable 14 to rotate via the rotating column 13. Because the turntable 14 is equipped with bumps 15, the solid organic tin moves slightly on the bumps 15 during rotation, and there is a gap between the bottom of the solid organic tin and the bump, which facilitates the drying of the bottom of the solid organic tin and ensures uniform drying. Because the solid organic tin may move, a buffer layer 19 is provided to prevent collision between the solid organic tin and the heating resistance wire 18. This buffer layer can alleviate the high temperature of the heating resistance wire 18, making the heating more uniform, and can also prevent the two from colliding and causing damage. When the motor button 6 and the bump 20 are about to make contact, the spring compresses the motor 9 switch to turn on. When the motor button 6 and the bump 20 are separated, the spring will return to its original shape due to the lack of pressure from the bump 20, and the motor 9 switch will turn off.

[0026] Specific implementation principle: When using this utility model, first assemble the parts into a whole, start the air pump 2 so that the clamping column 21 drives the conveyor belt 7 to move downward, place the solid organotin on the turntable 14, start the air pump 2 so that the rotating structure 4 moves upward and contacts the drying structure 5, the motor button 6 and the protrusion 20 engage, the motor 9 starts, and the heating resistance wire 18 is started. The solid organotin rotates on the turntable 14 and moves within a small range to prevent the bottom surface from drying. The exhaust gas generated during the drying process will be discharged into the exhaust gas collection box through the vent 17. Put the solid organotin to be dried into the rotating structure 4 on the rear side, start the air pump 2, the conveyor belt 7 moves downward, the rotating structure 4 stops rotating, start the conveyor belt 7 to replace the rotating structure 4 for drying treatment. The solid organotin on the front side will stay for a drying process to dissipate heat. When the conveyor belt 7 operates again, the cooled solid organotin falls into the solid organotin collection box under the action of gravity. Therefore, there are at least 8 rotating structures 4 on the conveyor belt 7.

[0027] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
