[0002] Catalyst generally refers to a substance that increases the reaction rate without changing the total standard Gibbs free energy of the reaction. It can also be described as a substance that can increase the chemical reaction rate without changing the chemical equilibrium in a chemical reaction, and its own quality and chemical properties have not changed before and after the chemical reaction. Catalyst kneader is a special mixing and stirring equipment. The most commonly used is two Σ blades, which are arranged in a side-by-side tangential differential speed type, that is, one stirring blade has a fast speed and the other has a slow speed, so as to generate shear force. Different blade speeds enable the mixed catalyst raw materials to be sheared quickly, so that the catalyst raw materials can be mixed evenly;

[0003] The mixing of catalyst raw materials is mainly produced in a kneading machine. When adding catalyst powder, the top cover of the kneading machine must be opened first, and then the bagged catalyst powder is added in batches. After each addition, the top cover of the kneading machine is closed and the stirring is started to stir it evenly. This is repeated until all the catalyst powder is added. This method of adding catalyst powder causes greater labor intensity and lower work efficiency for employees. In addition, there is a lot of dust when the catalyst powder is added, which greatly pollutes the working environment. Therefore, the utility model proposes a continuous kneading machine with automatic filling to solve the above problems. Utility Model Content

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an automatic filling continuous kneading machine, including a box body 1, a feed bin 2 and a cover plate 3. The top of the box body 1 is provided with a feed bin 2, and the top of the feed bin 2 is provided with an automatic filling mechanism. A cover plate 3 is fixed to one side of the feed bin 2, and a feed pipe 4 is connected to the outer side of the cover plate 3. The bottom of the box body 1 is connected to a discharge plate 5. A stirring mechanism is provided inside the box body 1. One end of the packaging bag containing catalyst powder is cut and the bag is put into the feed bin 2 through the feed pipe 4. The automatic filling mechanism generates suction and cooperates with people to shake the packaging bag to automatically transport the catalyst powder to the inside of the feed bin 2. At least the automatic filling mechanism back-blows the catalyst powder to make it enter the inside of the box body 1. The stirring mechanism inside the box body 1 stirs the catalyst powder and the colloid, so that they are evenly mixed inside the box body 1, and then transported to the outside of the box body 1 through the cover plate 3.

[0020] The automatic filling mechanism includes a connecting tube 6, a filter element 7, a fan 8, a pulse pump 9, a ventilation pipe 10 and an air storage tank 11. The fan 8 is installed on the top of the feed bin 2, and the input end of the fan 8 is connected to the connecting tube 6. The bottom end of the connecting tube 6 runs through the interior of the feed bin 2 and is connected to the filter element 7. The outer side of the connecting tube 6 is connected to the ventilation pipe 10. One end of the ventilation pipe 10 is connected to the air storage tank 11. The outer side of the ventilation pipe 10 is installed with a pulse pump 9. Since the input end of the fan 8 is connected to the interior of the filter element 7 through the connecting tube 6, the fan 8 can generate suction inside the filter element 7, and after the catalyst powder in the packaging bag enters the interior of the feed bin 2, it can be attracted to prevent it from floating outward, and at the same time The catalyst powder automatically falls into the interior of the casing 1 due to gravity. When the fan 8 inhales air, some gas enters the gas storage tank 11. When it is necessary to clean the catalyst powder on the surface of the filter element 7 and make it fall into the interior of the casing 1, the solenoid valve at the output end of the fan 8 is closed first. Then, the pulse pump 9 compresses the gas inside the gas storage tank 11 through the ventilation pipe 10 and releases it to the interior of the filter element 7 to backflush the filter element 7. The shock wave generated by the pulse airflow is used to shake off the catalyst powder on the surface of the filter element 7 and make it enter the interior of the casing 1 to avoid waste. Then, the solenoid valve at the output end of the fan 8 is opened and the pulse pump 9 is closed. In this way, when the fan 8 is started, it can continue to attract the catalyst powder into the interior of the feed bin 2.

[0021] The stirring mechanism includes a stirring shaft 12, a gear 13, a reducer 14, a No. 1 motor 15 and a connecting shaft 16. The stirring shaft 12 is symmetrically rotated inside the box 1. One end of the stirring shaft 12 passes through the inside of the box 1 and is connected to the gear 13. The outer sides of the two gears 13 are meshed with each other. One side of one of the gears 13 is connected to the reducer 14 through the connecting shaft 16. The input end of the reducer 14 is equipped with a No. 1 motor 15. The No. 1 motor 15 drives the connecting shaft 16 to rotate at a reduced speed through the reducer 14. Since the connecting shaft 16 is connected to one of the stirring shafts 12, and the gears 13 at one end of the two stirring shafts 12 are meshed with each other, the connecting shaft 16 can drive the two stirring shafts 12 to rotate towards each other at the same time inside the box 1, so as to stir the catalyst powder and the colloid for automatic mixing through the stirring shaft 12.

[0022] The bottom of the box body 1 is set to a "W"-shaped structure, and the bottom end of the box body 1 is provided with a strip groove connected to the inside of the discharge plate 5. The discharge plate 5 is provided with an automatic discharge mechanism, and the automatic discharge mechanism includes an auger 17 and a No. 2 motor 18. The auger 17 is rotatably installed inside the discharge plate 5, and the No. 2 motor 18 is installed at one end of the discharge plate 5. The output end of the No. 2 motor 18 passes through the inside of the discharge plate 5 and is connected to one end of the auger 17. When the colloid and catalyst powder in the box body 1 are in a stirring state, the No. 2 motor 18 drives the auger 17 to rotate in the opposite direction inside the discharge plate 5, and the auger 17 drives the colloid and the catalyst powder to move in a direction away from the outlet of the discharge plate 5, so that the colloid and the catalyst powder are always present in the inside of the box body 1. When the colloid and the catalyst powder are mixed, the No. 2 motor 18 drives the auger 17 to rotate forward inside the discharge plate 5, and the auger 17 drives the colloid and the catalyst powder to move toward the outlet of the discharge plate 5, so as to facilitate automatic discharge to the outside.

[0023] The filter element 7 is composed of a cylinder, activated carbon strips and a filter screen. A plurality of activated carbon strips are equidistantly distributed in an annular shape inside the cylinder, and a filter screen is provided outside the activated carbon strips.

[0024] The front of the feed bin 2 is provided with an inclined surface, and the cover plate 3 and the inclined surface are symmetrically provided with a group of screw holes, and bolts are provided inside the screw holes. The cover plate 3 is detachably connected to the inclined surface by bolts, and the cover plate 3 can be detachably installed on the front of the feed bin 2 by bolts. When the automatic filling mechanism fails, the cover plate 3 can be removed by unscrewing the bolts, so that people can enter the interior of the feed bin 2 to repair the automatic filling mechanism, and then the cover plate 3 is installed back to the front of the box body 1 by bolts.

[0025] The kneading machine can generate suction inside the filter element 7 through the fan 8, and can attract the catalyst powder in the packaging bag after it enters the inside of the feed bin 2 to prevent it from floating outward. At the same time, the catalyst powder automatically falls into the inside of the box 1 through the action of gravity. When the fan 8 inhales air, part of the gas will enter the gas storage tank 11. When it is necessary to clean the catalyst powder on the surface of the filter element 7 and make it fall into the inside of the box 1, the solenoid valve at the output end of the fan 8 is first closed, and then the pulse pump 9 compresses the gas in the gas storage tank 11 through the ventilation pipe 10 and releases it into the inside of the filter element 7, so as to backflush the filter element 7, and use the shock wave generated by the pulse airflow to shake the catalyst powder on the surface of the filter element 7 into the box 1.
