[0024] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by those skilled in the art to which the present application belongs. The terms used in the present application are only for the purpose of describing the specific embodiments of the present application, and are not used to limit the present application.

[0025] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0026] The preferred embodiments of the present application will be further described with reference to the accompanying drawings. In the drawings, Figures 1 to 3 As shown in the drawings, the purification device for waste silicone material recycling includes a workbench 10, a purification kettle 100 is arranged in the workbench 10, the purification kettle 100 is arranged in the workbench 10 in a semi-sunken manner, the purification kettle 100 is used for placing waste silicone material to be purified and corresponding chemical reagents, a stirring device 110 is arranged at the top of the purification kettle 100, the stirring device 110 is used for stirring the waste silicone material in the purification kettle 100, a heating device (not shown in the figure) is arranged at the bottom of the purification kettle 100, a first collection tank 200 is arranged on one side of the purification kettle 100, the height of the first collection tank 200 is lower than the height of the purification kettle 100, the first collection tank 200 is also arranged in the workbench 10 in a semi-sunken manner, a condenser pipe 300 is connected between the purification kettle 100 and the first collection tank 200, the condenser pipe 300 is arranged in a downward inclined manner from the purification kettle 100 to the first collection tank 200 at an angle of 15 degrees from high to low.

[0027] When the waste silicone material needs to be purified, the bottom of the purification kettle 100 is heated by using the heating device, and then the stirring device 110 is started to fully stir the waste silicone material and the chemical reagents in the purification kettle 100 at the same time, so that the impurities of the waste silicone material are vaporized and separated out at high temperature, and then flow into the first collection tank 200 after being cooled into a liquid state in the condenser pipe 300. Since the height of the first collection tank 200 is lower than the height of the purification kettle 100, and the condenser pipe 300 is arranged in a downward inclined manner at an angle of 15 degrees from high to low, compared with the prior art, the vaporized impurities can stay in the condenser tank for a longer time, so that they have sufficient time to cool into a liquid state. At the same time, the liquid state impurities formed by cooling can also continue to flow into the first collection tank 200 along the condenser pipe 300.

[0028] In addition to the above embodiments, in combination with Figure 2 and Figure 3As shown, one end of the condensing pipe 300 is connected with the first communication pipe 120 between the purification kettle 100, the first communication pipe 120 is arranged at the top of the purification kettle 100, and the inner diameter of the first communication pipe 120 is smaller than the inner diameter of the condensing pipe 300. In the working of the purification kettle 100, impurities will be vaporized and separated out at high temperature, and the steam will flow into the condensing pipe 300 through the first communication pipe 120. Because the inner diameter of the first communication pipe 120 is smaller than the inner diameter of the condensing pipe 300, the flow rate is equal to the flow velocity multiplied by the cross-sectional area, that is, Q=U*A (Q is the flow rate, U is the flow velocity, and A is the cross-sectional area). In the incompressible stable fluid, the fluid mass flowing through each cross section of the pipe is equal. When the cross-sectional area of the pipe becomes larger (the inner diameter becomes larger), in order to keep the volume of the fluid flowing per unit time unchanged, the flow velocity will be reduced accordingly, so the flow velocity of the steam in the vent pipe 131 will be significantly reduced, so that the steam stays in the condensing pipe 300 for a longer time, thereby more conducive to cooling the vaporized impurities into a liquid state, thereby further improving the cooling effect.

[0029] Further based on the above embodiment, in combination with Figure 2 and Figure 3 As shown, the end of the condensing pipe 300 away from the first communication pipe 120 is connected with the second communication pipe 210, and the second communication pipe 210 is vertically arranged at the top of the first collection tank 200. In this way, when the vaporized impurities are cooled into a liquid state in the condensing pipe 300, they can directly and quickly enter the first collection tank 200 through the second communication pipe 210, thereby avoiding the impurities staying in the second communication pipe 210 for too long time and forming a blockage in the second communication pipe 210.

[0030] Further based on the above embodiment, in combination with Figure 2 and Figure 3 As shown, the stirring device 110 includes a stirring motor 111 arranged at the top of the purification kettle 100, and a stirring paddle 112 connected to the bottom of the stirring motor 111 and extending into the interior of the purification kettle 100. The stirring motor 111 can drive the stirring paddle 112 to rotate, thereby achieving sufficient stirring between the waste silica gel material and the chemical agent in the purification kettle 100.

[0031] In some embodiments, in combination with Figure 2 As shown, an air extractor 130 is arranged on the purification kettle 100 and connected with the purification kettle 100 through a vent pipe 131. When the air extractor 130 is started, the air in the purification kettle 100 can be extracted through the vent pipe 131. In this way, by reducing the pressure in the purification kettle 100, the impurities in the waste silica gel material can be vaporized and separated out at a lower temperature, thereby further improving the purification effect.

[0032] Further based on the above-mentioned embodiments, in combination with Figure 2 and Figure 3 As shown in the figure, a discharge port 140 is arranged on the top of the purification kettle 100, which is used to put the mixture of waste silica gel material and chemical agent into the purification kettle 100, and a sealing cover 141 is arranged on the discharge port 140.

[0033] Further based on the above-mentioned embodiments, as shown in the figure, Figure 4 A second collecting tank 400 is arranged on the side of the first collecting tank 200 away from the purification kettle 100, a third communicating pipe 410 is communicated with the top of the second collecting tank 400, the third communicating pipe 410 is connected with the second communicating pipe 210 and is arranged in an inclined manner, so that the first collecting tank 200 and the second collecting tank 400 are communicated with each other, and thus when the first collecting tank 200 is full of impurities, the liquid impurities can flow into the second collecting tank 400 through the third communicating pipe.

[0034] In some embodiments, as shown in the figure, Figure 4 A first valve 211 is arranged on the second communicating pipe 210, and a second valve 411 is arranged on the third communicating pipe 410, in the normal state, the first valve 211 is in an open state, and the second valve 411 is in a closed state, the liquid impurities flow into the first collecting tank 200 through the second communicating pipe 210, when the first collecting tank 200 is full of impurities, the first valve 211 is closed, and the second valve 411 is opened, so that the liquid impurities can flow into the second collecting tank 400 through the third communicating pipe 410.

[0035] The details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic features of the present application, the present application can be realized in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
