[0025] In the present device, the feeding and discharging of materials are realized by means of a feeding pipe 11 and a discharging pipe 12 respectively arranged at the top and the bottom of the reactor 1. The stirring end of the stirring mechanism 2 is arranged in the reactor 1, which can stir the materials inside the reactor 1 so that the produced materials are fully mixed to improve the production efficiency. At the same time, a sliding filtering bottom plate 3 is arranged at the bottom of the reactor 1. The outer surface of the filtering bottom plate 3 fits with the inner surface of the bottom of the reactor so that it can be fitted at the bottom of the reactor 1 and will not affect the material reaction during the production work. After the production is completed, when discharging the material, the bottom plate adjusting mechanism 4 can be used to pull the filtering bottom plate 3 upward to make the filtering bottom plate 3 away from the bottom of the inner wall of the reactor 1. The material inside the reactor 1 can flow to the bottom of the reactor 1 and be discharged from the discharging pipe 12 after being filtered through the filtering bottom plate 3, so that the impurity particles in the silicone resin can be effectively screened out.

When implemented, the stirring motor 23 can drive the central axis 21 to rotate, drive the plurality of stirring rods 22 to rotate around the central axis 21, and realize stirring of the material.

[0028] In order to prevent impurities from clogging the filter base 3 and affecting the normal discharge of the silicone resin, the scraper 24 is fixed to the bottom end of the central axis 21, and the bottom end of the central axis 21 is suspended in the reactor 1, so that the scraper 24 and the bottom of the reactor 1 are spaced apart from each other to reserve a gap for the filter base 3 to slide upward. After the filter base 3 is pulled upward and slid to a certain distance, the upper surface of the filter base 3 can be fitted with the bottom surface of the scraper 24. When the bottom surface of the scraper 24 rotates around the central axis 21, it can form a scraping surface matching the upper surface of the filter base 3, so that the scraper 24 can scrape on the upper surface of the filter base 3 to prevent the filtered impurities from clogging the filter base 3 or solidifying.

When the reactor 1 is working normally, the filter bottom plate 3 is at the bottom of the reactor 1, and the drainage pipe 31 is built inside the discharge pipe 12.

[0031] Preferably, the filter bottom plate 3 is an elliptical hemispherical structure.

[0032] Of course, in other possible embodiments, the filter bottom plate 3 may also be a flat plate or a conical plate, etc.

[0033] In this example, see Figures 1 to 3 The bottom plate adjustment mechanism 4 is provided with two, which include an adjustment rod 41, a handle 42 and a latch 43. The two adjustment rods 41 are respectively arranged on both sides of the top of the filter bottom plate 3. The bottom end of the adjustment rod 41 will be fixedly connected to both sides of the top surface of the filter bottom plate 3, and its top end passes through the top of the reactor 1 and is connected to the handle 42. Each of the adjustment rods 41 is provided with two positioning holes 411, and the latch 43 is movably inserted in the positioning hole 411 to press against the top of the reactor 1 under the gravity of the adjustment rod 41 and the filter bottom plate 3.

The spray heads 51 can be used to rinse the inner wall of the reactor 1 and the filtering bottom plate 3, so as to facilitate cleaning of impurities remaining inside the reactor 1.

[0036] Working principle: During implementation, materials are added to the reactor 1 through the feed pipe 11. During the processing, the central shaft 21 and the stirring rod 22 can be driven to rotate by the stirring motor 23 to achieve stirring of the materials and make the materials mixed more evenly. During operation, materials can also be added to the reactor 1 through the filler connecting pipe 13. After the processing of the silicone resin solution is completed, the handle 42 can be used to pull the adjustment rod 41 upward to drive the filter bottom plate 3 to slide upward so that the top surface of the filter bottom plate 3 contacts the scraper 24, and then the latch 43 is inserted to The filter base plate 3 is positioned and fixed in the corresponding positioning hole 411. At this time, the discharge valve at the discharge pipe 12 can be opened to allow the silicone resin solution filtered by the filter base plate 3 to be discharged through the discharge pipe 12. After all the silicone resin solution is discharged, the nozzle 51 and the valve 32 are opened to flush the inner wall of the reactor 1 and the impurities on the filter base plate 3. The impurities can be discharged through the impurity discharge pipe 31 and the discharge pipe 12. After cleaning, the pin 43 is pulled out to reset the filter base plate 3 to the bottom of the reactor 1.

[0037] The utility model provides a filter bottom plate 3 and a bottom plate adjusting mechanism 4. When discharging materials, the filter bottom plate 3 can be pulled upward by the bottom plate adjusting mechanism 4 to keep the filter bottom plate 3 away from the bottom of the inner wall of the reactor 1. The materials inside the reactor 1 can flow to the bottom of the reactor 1 and be discharged from the discharge pipe 12 only after being filtered by the filter bottom plate 3. The impurity particles in the silicone resin can be effectively screened out, the quality of the produced silicone resin can be improved, and there is no need to set up an additional filtering device for filtering and removing impurities, which is beneficial to reducing production costs.

[0038] The utility model realizes screening by adopting a sliding filter bottom plate 3 inside the reaction kettle 1, so that the filter area is large and will not be easily blocked, thereby ensuring the screening ability of the organic silicon resin.
