AI Technical Summary
During the polypropylene production process, after the liquid catalyst is added, catalyst residue is prone to occur at the connection between the pipeline and the injection mechanism, resulting in a polymerization reaction under certain pressure and temperature conditions, forming polypropylene particles and blocking the filling pipeline.

DETAILED DESCRIPTION
[0013] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
[0014] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: a catalyst pipeline filling device for polypropylene production, comprising: A frame 1 having a frame supporting the mechanism assembly, and a white oil tank 5 and a medicine tank 6 are fixedly installed inside the frame 1, and the white oil tank 5 and the medicine tank 6 are symmetrically installed along the center position of the axis of the frame 1; The material guiding mechanism 2 is used for conducting the white oil and the catalyst, and the material guiding mechanism 2 is installed inside the frame 1; A material injection mechanism 3, which is used to inject the material guided by the material guiding mechanism 2 into the reaction kettle, and the material injection mechanism 3 is installed at one end of the material guiding mechanism 2; A connecting mechanism 4, which is used to fix the injection mechanism 3 at the introduction position of the reactor; The material guiding mechanism 2 comprises a three-way valve 213, which has two inlet pipes and one outlet pipe. The inlet pipe of the three-way valve 213 is respectively installed with an oil guiding pipe 205 and a secondary pipe 204. A rear section pipe 207 is fixedly installed at the outlet pipe of the three-way valve 213. A connector 208 is fixedly installed at one end of the rear section pipe 207 away from the three-way valve 213. The interior of the connector 208 has an arc-shaped pipe protruding outward at the center. The rear section pipe 207 is connected to the injection mechanism 3 through the connector 208. A groove plate 209 is fixedly installed at the center of the inner wall of the connector 208. A slider 210 is slidably installed at the center of the inner wall of the groove plate 209. An arc block 212 is fixedly installed at one end of the slider 210 close to the rear section pipe 207. During the white oil flushing process, the connection between the rear section pipe 207 and the injection mechanism 3 Position, because it is connected through the connecting head 208, when the white oil passes through, the flowing white oil impacts the arc surface of the arc surface block 212, pushing the arc surface block 212 to compress the elastic pad 211, so that the arc surface block 212 drives the slider 210 to slide in the direction of the injection mechanism 3. At the same time, during the sliding process, due to the arc surface protruding outward from the center of the inner wall of the connecting head 208, the flow gap between the connecting head 208 and the slider 210 is reduced, and the flow rate is increased. An elastic pad 211 is installed between the arc surface block 212 and the groove plate 209, and the end of the arc surface block 212 close to the rear section pipe 207 is an inwardly concave arc surface, and the end of the connecting head 208 away from the rear section pipe 207 is fixedly connected to the injection mechanism 3, and the end of the oil guide pipe 205 away from the three-way valve 213 is installed with an oil pump 206, and the end of the secondary pipe 204 away from the three-way valve 213 is installed with a medicine pump 203.
[0015] The bottom of the chemical pump 203 and the oil pump 206 are fixedly connected to the top of the frame 1, the outlet end of the chemical pump 203 is connected to the secondary pipe 204, and the outlet end of the oil pump 206 is connected to the oil guide pipe 205. First, the conduction path between the rear section pipe 207 and the secondary pipe 204 is opened through the three-way valve 213, and the catalyst in the chemical tank 6 is conducted in the order of the primary pipe 202, the secondary pipe 204 and the rear section pipe 207 through the chemical pump 203, so that the chemical is introduced into the injection mechanism 3 through the connector 208, and the catalyst is introduced into the reactor through the injection mechanism 3. The inlet end of the oil pump 206 is installed with a white oil pipe 201, and the white oil pipe 201 is away from the oil pump 206. The end is connected with the white oil tank 5, and the inlet end of the chemical pump 203 is installed with a primary pipe 202. When the catalyst is filled, the chemical pump 203 stops running, and at the same time, the three-way valve 213 closes the conduction path between the secondary pipe 204 and the rear section pipe 207, and opens the conduction path between the oil guide pipe 205 and the rear section pipe 207. By starting the oil pump 206, the white oil in the white oil tank 5 is conducted in sequence through the white oil pipe 201, the oil guide pipe 205 and the rear section pipe 207, and the chemical residue in the rear section pipe 207 is flushed with anhydrous white oil to clean the catalyst residue in the rear section pipe 207. The end of the primary pipe 202 away from the chemical pump 203 is connected with the chemical tank 6.
[0016] The second embodiment is based on the first embodiment. Figure 6 to Figure 7 As shown, the injection mechanism 3 includes a front section pipe 31, one end of the front section pipe 31 is fixedly connected to one end of the connector 208 away from the rear section pipe 207, and the other end of the front section pipe 31 is fixedly installed with a ball valve 32. The front section pipe 31 is connected to the connector 208, so that the derived catalyst or white oil is introduced into the ball valve 32 through the front section pipe 31, and finally the material is conducted through the rear section pipe 33 and the filling elbow 35, so that the catalyst or white oil is introduced into the reactor from the outlet end of the filling elbow 35. The inlet end of the ball valve 32 is connected to the front section pipe 31, and the outlet end of the ball valve 32 is fixedly installed with the rear section pipe 33. The inner diameter of the segment pipe 31 becomes smaller as it gets closer to the ball valve 32, and the diameter of the rear segment pipe 33 is smaller than that of the front segment pipe 31. When the material flows through, the front segment pipe 31 cooperates with the rear segment pipe 33, and the change in the inner diameter of the front segment pipe 31 is used to make the material quickly impact the ball valve 32 when flowing through. After the material passes through the ball valve 32, the aperture of the outlet end of the filling elbow 35 changes, so that the material rushes into the reactor at high speed. The end of the rear segment pipe 33 away from the ball valve 32 is threadedly connected with the filling elbow 35, and the aperture of the outlet end of the filling elbow 35 gradually decreases, and a gasket ring 34 is installed between the filling elbow 35 and the rear segment pipe 33.
[0017] The third embodiment is based on the first and second embodiments. Figures 8 to 9 As shown, the connecting mechanism 4 includes a fixed tube 41, the inner wall of which is fixedly connected to the outer side of the filling elbow 35, a flange 42 is fixedly installed on the outer side of the fixed tube 41, and the fixed tube 41 is flange-connected to the outlet position of the reactor through the flange 42. A beveled cylinder 43 is fixedly installed on the outer side of the fixed tube 41, and one end of the beveled cylinder 43 is fixedly connected to the outer side of the flange 42. The fixed tube 41 is inserted into the pipeline at the inlet position of the reactor together with the injection mechanism 3, and is flange-connected to the pipeline of the reactor through the flange 42. When the fixed tube 41 is inserted into the pipeline, the inner gasket 44 and the rubber ring 45 are driven into the interior of the pipeline through the beveled cylinder 43, and a limiting ring 46 is fixedly installed on the other end of the beveled cylinder 43.
[0018] The outer side of the bevel cylinder 43 is a bevel, and the outer diameter gradually decreases in the process of gradually moving away from the flange 42. A rubber ring 45 is provided on the outer side of the bevel cylinder 43. An inner gasket 44 is installed between the rubber ring 45 and the bevel cylinder 43. The inner gasket 44 is symmetrically arranged along the center position of the rubber ring 45. The rubber ring 45 is slidably installed on the outer side of the bevel cylinder 43 through the inner gasket 44. During the insertion process, the rubber ring 45 and the clamping ring 47 contact the inner wall of the pipeline. The friction between the rubber ring 45 and the inner wall of the pipeline drives the clamping ring 47 and the inner gasket 44 to slide together. During the sliding process, the inner gasket 44 cooperates with the inclined surface of the bevel cylinder 43 to squeeze the rubber ring 45 outward, increase the friction between the rubber ring 45 and the inner wall of the pipeline, until the inner gasket 44 can no longer slide on the outer side of the bevel cylinder 43, and then continue to insert it into the pipeline, and finally the flange 42 is connected to the pipeline flange. Clamping rings 47 are fixedly installed on both sides of the rubber ring 45.
[0019] When in use, the staff pours the catalyst and anhydrous white oil into the reagent tank 6 and the white oil tank 5 for storage respectively, installs the injection mechanism 3 at the introduction position of the reactor through the connecting mechanism 4, and seals the connection position through the connecting mechanism 4. When the node where the catalyst needs to be added is reached, the catalyst is introduced into the reactor through the injection mechanism 3 through the material guiding mechanism 2, and after the filling, the rear section of the filling path is cleaned with white oil.
[0020] When the catalyst is introduced and cleaned through the material guiding mechanism 2, the conduction path between the rear section pipe 207 and the secondary pipe 204 is first opened through the three-way valve 213, and the catalyst in the reagent tank 6 is conducted in the order of the primary pipe 202, the secondary pipe 204 and the rear section pipe 207 through the reagent pump 203, so that the reagent is introduced into the injection mechanism 3 through the connector 208, and the catalyst is introduced into the reactor through the injection mechanism 3. When the catalyst is filled, the reagent pump 203 stops running, and at the same time, the three-way valve 213 closes the conduction path between the secondary pipe 204 and the rear section pipe 207, opens the conduction path between the oil guide pipe 205 and the rear section pipe 207, and starts the oil pump 206 to inject the white oil in the white oil tank 5 through the white oil pump 206. The oil is sequentially conducted through the pipe 201, the oil guide pipe 205 and the rear section pipe 207, and the residual agent in the rear section pipe 207 is flushed with anhydrous white oil to clean the residual catalyst in the rear section pipe 207. At the same time, during the white oil flushing process, the connection position of the rear section pipe 207 and the injection mechanism 3 is connected through the connector 208. When the white oil passes through, the flowing white oil impacts the arc surface of the arc surface block 212, pushing the arc surface block 212 to compress the elastic pad 211, so that the arc surface block 212 drives the slider 210 to slide in the direction of the injection mechanism 3. At the same time, during the sliding process, due to the arc surface protruding outward from the center of the inner wall of the connector 208, the flow gap between the connector 208 and the slider 210 is reduced, thereby increasing the flow rate.
[0021] In the injection mechanism 3, the front section pipe 31 is connected to the connector 208, so that the exported catalyst or white oil is introduced into the ball valve 32 through the front section pipe 31, and finally the material is conducted through the rear section pipe 33 and the filling elbow 35, so that the catalyst or white oil is introduced into the reactor from the outlet end of the filling elbow 35. At the same time, when the material flows through, the front section pipe 31 and the rear section pipe 33 cooperate, and the inner diameter change of the front section pipe 31 is utilized to make the material quickly impact the ball valve 32 when flowing through. After the material passes through the ball valve 32, the aperture change of the outlet end of the filling elbow 35 causes the material to rush into the reactor at high speed.
[0022] When the injection mechanism 3 is installed at the introduction position of the reactor through the connecting mechanism 4, the fixed tube 41 together with the injection mechanism 3 is inserted into the pipeline at the introduction position of the reactor, and connected to the pipeline flange of the reactor through the flange 42. When the fixed tube 41 is inserted into the pipeline, the inner pad 44 and the rubber ring 45 are driven to enter the interior of the pipeline through the inclined tube 43. At the same time, during the insertion process, the rubber ring 45 and the clamp ring 47 contact the inner wall of the pipeline. Through the friction between the rubber ring 45 and the inner wall of the pipeline, the clamp ring 47 and the inner pad 44 are driven to slide together. In the sliding process, the inner pad 44 cooperates with the inclined surface of the inclined tube 43 to squeeze the rubber ring 45 outward, thereby increasing the friction between the rubber ring 45 and the inner wall of the pipeline, until the inner pad 44 cannot slide on the outside of the inclined tube 43, and then continue to insert it into the pipeline, and finally connect the flange 42 to the pipeline flange.
[0023] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
