Description

Technical Field

[0001] This utility model belongs to the field of dehydration equipment technology, specifically relating to a dehydration device for producing organotin catalysts. Background Technology

[0002] In the production of organotin catalysts, dehydration is one of the key processes, and its efficiency and stability directly affect product quality and energy consumption. Traditional dehydration devices generally suffer from poor heating uniformity and insufficient liquid level control: when the throughput changes, the fixed volume of the heating and dehydration zone is prone to excessively high or low liquid levels—too high a liquid level will cause insufficient heating of the material above the heater, prolonging the dehydration time; too low a liquid level may expose the heating elements above the liquid surface, causing dry burning or even equipment damage. Utility Model Content

[0003] The purpose of this invention is to provide a dehydration device for producing organotin catalysts, which can control the liquid level of the organotin catalyst in the heating and dehydration zone, reduce the phenomenon of uneven heating of the heater due to excessively high liquid level, and reduce the phenomenon of dry burning caused by the heating element of the heater being directly exposed on the liquid surface due to excessively low liquid level, thereby reducing the phenomenon of heater damage.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A dehydration apparatus for producing organotin catalysts includes a rectangular heat-insulating shell, inside which a heating and dehydration zone is provided, the horizontal cross-sectional dimension of which is adjustable;

[0006] A feed inlet connected to the heating and dehydration zone is fixedly connected to the middle position of the side of the rectangular heat-insulating shell. A discharge port connected to the heating and dehydration zone is fixedly connected to the middle position of the lower side of the rectangular heat-insulating shell. A gas output port connected to the heating and dehydration zone is fixedly connected to the middle position of the upper side of the rectangular heat-insulating shell. A vacuum system connected to the heating and dehydration zone is fixedly connected to the rectangular heat-insulating shell. A heater is installed inside the heating and dehydration zone.

[0007] Furthermore, two partitions are installed inside the rectangular heat-insulating shell, and the heating and dehydration zone is the space inside the rectangular heat-insulating shell located between the two partitions. A horizontal moving device that is drivenly connected to the partitions is fixedly connected to the rectangular heat-insulating shell.

[0008] Furthermore, the horizontal mobile device includes an electric telescopic rod fixedly connected to the side of the rectangular insulated shell, and the piston rod and the partition of the electric telescopic rod are fixedly connected.

[0009] Furthermore, a sealing ring is fixedly connected to the side of the partition.

[0010] Furthermore, the side of the partition is provided with a groove, and the sealing ring is engaged inside the groove.

[0011] Furthermore, an air cavity is provided inside the sealing ring, and an air pressure regulating mechanism that communicates with the air cavity is fixedly connected to the rectangular heat-insulating shell.

[0012] Furthermore, the air pressure regulating mechanism includes an air pump fixedly connected to the outside of the rectangular heat-insulating shell, and the air pump is connected to the air chamber of the sealing ring through a hose.

[0013] Furthermore, the heater includes multiple resistance heating elements, and connecting strips are fixedly connected to both the upper and lower ends of the multiple resistance heating elements. Tension springs are fixedly connected between two adjacent connecting strips and between adjacent connecting strips and partitions.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention relates to a dehydration device for producing organotin catalysts. By adjusting the horizontal cross-sectional dimensions of the heating and dehydration zone, the volume of the heating and dehydration zone is matched with the amount of organotin catalyst entering the zone. In other words, the amount of material determines the horizontal cross-sectional dimensions, thereby controlling the liquid level. This controls the liquid level of the organotin catalyst in the heating and dehydration zone, bringing it closer to the gas outlet. This reduces the steam rising path, lowers the heat energy lost during steam rise, and also reduces uneven heating caused by excessively high liquid levels. Furthermore, it reduces dry burning caused by excessively low liquid levels, which exposes the heating elements directly to the liquid surface, thus reducing the risk of heater damage.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4 As shown, a dehydration device for producing organotin catalysts includes a rectangular heat-insulating shell 1, and a heating and dehydration zone is provided inside the rectangular heat-insulating shell 1. The organotin catalyst enters the heating and dehydration zone for dehydration treatment.

[0024] A feed inlet 3, which is connected to the heating and dehydration zone, is fixedly connected to the middle position of the side of the rectangular heat-insulating shell 1. The organic tin catalyst to be dehydrated can be added into the heating and dehydration zone relatively easily through the feed inlet 3.

[0025] A discharge port 2, which is connected to the heating and dehydration zone, is fixedly connected to the middle position of the lower side of the rectangular heat-insulating shell 1. A valve is installed on the discharge port 2. After dehydration is completed, the valve is opened to discharge the dehydrated organotin catalyst.

[0026] A gas outlet 4, which is connected to the heating and dehydration zone, is fixedly connected to the middle position of the upper side of the rectangular heat-insulating shell 1. The gas generated during the dehydration process can be discharged through the gas outlet 4. The gas outlet 4 is connected to the condenser, and the gas directly enters the condenser for condensation.

[0027] A vacuum system connected to the heating and dehydration zone is fixedly connected to the rectangular heat-insulating shell 1. This system is used to reduce the gas pressure inside the heating and dehydration zone after feeding is completed, thereby reducing the boiling point of the organotin catalyst.

[0028] The composition of one type of vacuum system is disclosed herein. The vacuum system includes a vacuum pump connected to a heating and dehydration zone, a vacuum buffer tank connected to the vacuum pump, and a vacuum pressure gauge installed on the vacuum buffer tank.

[0029] A heater is installed inside the heating and dehydration zone to heat the organotin catalyst inside the zone, causing the water in the organotin catalyst to vaporize and then be discharged through gas outlet 4.

[0030] The core of this technical solution lies in the adjustable horizontal cross-sectional dimensions of the heating and dehydration zone, which makes the volume of the heating and dehydration zone and the amount of organotin catalyst entering the heating and dehydration zone compatible. In other words, the amount of material determines the horizontal cross-sectional dimensions, thereby controlling the liquid level height of the organotin catalyst in the heating and dehydration zone.

[0031] The horizontal cross-sectional dimensions of the heating and dehydration zone can be dynamically adjusted according to the amount of material, so that the liquid level is maintained within the set range. This makes the liquid level of the organotin catalyst close to the gas outlet 4, reducing the steam rising path and the heat energy lost during steam rise. It also reduces the phenomenon of uneven heating of the heater due to excessively high liquid level, and reduces the phenomenon of dry burning caused by the heating element of the heater being directly exposed on the liquid surface due to excessively low liquid level, thus reducing the possibility of heater damage.

[0032] Among them, such as Figures 1-3 As shown, there are multiple ways to adjust the horizontal cross-sectional dimensions. In this technical solution, the horizontal cross-sectional dimensions of the heating and dehydration zone are adjusted by adjusting the length of the heating and dehydration zone. Specifically, two partitions 6 are installed inside the rectangular insulation shell 1. The heating and dehydration zone is the space inside the rectangular insulation shell 1 located between the two partitions 6. The distance between the two partitions 6 is the length of the heating and dehydration zone.

[0033] A horizontal moving device is fixedly connected to the rectangular heat-insulating shell 1 and is driven by the partition 6. By moving the partition 6 through the horizontal moving device, the position of the two partitions 6 can be adjusted, and the length of the heating and dehydration zone can be adjusted. Thus, the horizontal cross-sectional size of the heating and dehydration zone can be adjusted using a relatively simple structure.

[0034] like Figures 2-3 As shown, the horizontal moving device includes an electric telescopic rod 5 fixedly connected to the side of the rectangular insulated shell 1. The piston rod of the electric telescopic rod 5 is fixedly connected to the partition 6. The position of the partition 6 can be adjusted by controlling the electric telescopic rod 5, thereby realizing the electric adjustment of the partition 6.

[0035] To ensure airtightness, a sealing ring 8 is fixedly connected to the side of the partition 6. The sealing ring 8 fills the gap between the partition 6 and the inner wall of the rectangular insulation shell 1, thus ensuring airtightness. At the same time, a groove 7 can be opened on the side of the partition 6. The sealing ring 8 is snapped into the inside of the groove 7. The groove 7 can be used to position the sealing ring 8, reducing the phenomenon of the sealing ring 8 falling off when the partition 6 moves.

[0036] To further improve sealing performance, this technical solution has made further improvements to the sealing ring 8, such as... Figures 2-4 As shown, an air cavity is provided inside the sealing ring 8, and an air pressure regulating mechanism that communicates with the air cavity is fixedly connected to the rectangular heat insulation shell 1.

[0037] When the partition 6 moves, the air pressure in the air chamber is reduced by the air pressure regulating mechanism, which causes the sealing ring 8 to contract, reducing the pressure between the sealing ring 8 and the rectangular heat insulation shell 1, and reducing wear during the movement of the partition 6.

[0038] After the partition 6 has moved, the air pressure in the air chamber can be increased by adjusting the mechanism, which will cause the sealing ring 8 to expand, increase the pressure between the sealing ring 8 and the rectangular heat-insulating shell 1, and improve the sealing performance.

[0039] Specifically, the air pressure regulating mechanism includes an air pump 9 fixedly connected to the outside of the rectangular insulation shell 1. The air pump 9 is connected to the air chamber of the sealing ring 8 through the hose 10. At this time, the pressure of the air chamber can be adjusted by controlling the air pump 9.

[0040] like Figures 2-4 As shown, the heater includes multiple resistance heating elements 13. Each of the upper and lower ends of the multiple resistance heating elements 13 is fixedly connected to a connecting strip 12. A tension spring 11 is fixedly connected between two adjacent connecting strips 12 and between adjacent connecting strips 12 and the partition 6. When the partition 6 moves, the tension spring 11 pulls the connecting strip 12, which can automatically adjust the position of the connecting strip 12 so that the resistance heating elements 13 on the connecting strip 12 are distributed more evenly between the two partitions 6.

[0041] Meanwhile, the connecting strip 12 is preferably made of ceramic to reduce the heat energy transferred from the resistance heating element 13 to the tension spring 11.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
