[0011] A method for preparing a diisopropylbenzene hydroperoxide preparation device comprises the following steps:

[0012] S1. First, the raw materials are pretreated and oxidized, and then the concentrated semi-finished product diisopropylbenzene hydroperoxide and the diatomaceous earth filter are injected into the mixing box body and started. The driving motor is started. The driving motor drives the telescopic stirring rod to rotate in the mixing box body, and drives the stirring blades to rotate to stir and mix. When the telescopic stirring rod rotates, it drives the annular rotating rod at the upper end to rotate. When the annular rotating rod rotates, it drives the intermittent wheel to rotate slowly. The intermittent wheel rotates in the mixing box body through the telescopic rod. When the intermittent wheel rotates, it drives the rotating rod on the side to rotate slowly. When the rotating rod rotates, it drives the eccentric gear to rotate. The rotation of the eccentric gear When the gear rotates, it drives the meshing gear to rotate. When the gear rotates, it drives the eccentrically rotating connected extension rod to gradually slide downward in the U-shaped frame. When the extension rod slides downward, it drives the L-shaped rod at the lower end to move downward. The L-shaped rod drives the telescopic stirring rod to gradually extend. At the same time, when the telescopic stirring rod is about to drop to the bottom, the extension rod drives the side extrusion rod to slide downward and squeezes the inclined surface of the inclined rod. The inclined rod will slide to the right inside the limiting slide groove. At the same time, the inclined rod drives the entire intermittent wheel to slide on the telescopic rod and slide on the surface of the rotating rod. At this time, the intermittent wheel will separate from the annular rotating rod, and the telescopic stirring rod will continue to rotate.

[0013] S2. When the telescopic stirring rod is gradually extended, the hinged rod is driven to move downward at the same time. The hinged rod will first enter the threaded sleeve, driving the threaded sleeve to rotate while squeezing the cross bar through the threaded sleeve. When the cross bar is squeezed, it will squeeze the fixed rod at the same time. The fixed rod drives the right baffle and the left baffle to open relatively, and the cross bar will slide in the sliding groove opened in the fixed rod. At this time, the cross bar is continuously squeezed, driving the right baffle and the left baffle to rotate and open, and form a V-shaped opening, and the two ends of the fixed rod will slide to the position where the fixed rod is close to the impact rod. When the right baffle and the left baffle are opened, the right baffle drives the coarse filter to rotate with the lower end of the connecting rod as the center through the connecting rod, so that the coarse filter is tilted, and pre-filtration is first performed. Diisopropylbenzene hydroperoxide will enter the next process. At the same time, the threaded sleeve drives the impact rod to rotate, and it will continuously hit the inclined rod, causing it to drive the cross bar and the fixed rod to deform and shake, and then be discharged from the opening on one side of the machine body;

[0014] S3, the semi-finished product diisopropylbenzene hydroperoxide will enter the surface of the high-toughness filter screen, and the high-toughness filter screen will continue to operate through the active electric roller and the driven roller. The double-layer high-toughness filter screen can ensure the filtering effect. At the same time, when the high-toughness filter screen rotates, the filtering rate can be increased, and then it will be discharged from the transport pipe and enter the next process;

[0015] S4. Before that, when the driven roller rotates, it drives the eccentric shaft to rotate. When the eccentric shaft rotates, it drives the connecting rod 1, and the rotating teeth are pushed or pulled by the round rod to swing back and forth with the rotating rod as the center. At the same time, when the eccentric shaft rotates, it also drives the knocking rod to rotate. When the knocking rod rotates, it continuously hits the vibration rod in the driven roller, causing it to vibrate, thereby causing the driven roller to vibrate. When the driven roller vibrates, it drives the entire high-toughness filter to vibrate;

[0016] S5. Finally, at the end, the driving motor is stopped and the reset electric rotating rod is started to drive the eccentric gear to rotate in the opposite direction, so that the extension rod moves upward, thereby resetting all mechanisms and returning to the initial state.

[0017] In the present invention, the coarse filter screen is tilted, and the threaded sleeve drives the impact rod to rotate, which will continuously impact the inclined rod, causing deformation and shaking between the cross rod and the fixed rod, thereby driving the coarse filter screen to produce a certain vibration, thereby improving the filtering effect and quickly shaking off the debris and discharging it from the opening on one side of the machine body.

[0018] In the present invention, when the eccentric shaft rotates, the connecting rod drives the round rod, pushing or pulling the rotating teeth to swing back and forth with the rotating rod as the center, thereby cleaning the side of the high-toughness filter net, preventing debris from remaining on the surface or in the gaps of the high-toughness filter net, and improving the filtering effect.

[0019] In the present invention, when the eccentric shaft rotates, the knocking rod will also be driven to rotate. When the knocking rod rotates, it will continuously hit the vibration rod in the driven roller to cause it to vibrate, thereby causing the driven roller to vibrate. When the driven roller vibrates, it will drive the entire high-toughness filter net to vibrate, thereby further improving the filtering efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 As shown;

[0040] S1. First, the raw materials are pretreated and oxidized, and then the concentrated semi-finished product diisopropylbenzene hydroperoxide and the diatomaceous earth filter are injected into the mixing box body 2 and started. The drive motor 41 is started. The drive motor 41 drives the telescopic stirring rod 42 to rotate in the mixing box body 2, and drives the stirring blades 43 to rotate to stir and mix. When the telescopic stirring rod 42 rotates, it drives the annular rotating rod 51 at the upper end to rotate. When the annular rotating rod 51 rotates, it drives the intermittent wheel 53 to rotate slowly. The intermittent wheel 53 rotates in the mixing box body 2 through the telescopic rod 52.

At this time, the intermittent wheel 53 will be separated from the annular rotating rod 51, and the telescopic stirring rod 42 continues to rotate.

[0041] S2. When the telescopic stirring rod 42 is gradually extended, the hinged rod 44 is driven to move downward at the same time. The hinged rod 44 will first enter the threaded sleeve 74, and while driving the threaded sleeve 74 to rotate, the cross rod 73 is squeezed through the threaded sleeve 74. When the cross rod 73 is squeezed, the fixed rod 71 is squeezed at the same time. The fixed rod 71 drives the right baffle 61 and the left baffle 62 to open relatively. At the same time, the cross rod 73 will slide in the sliding groove 72 opened in the fixed rod 71. At this time, the cross rod 73 is continuously squeezed, driving the right baffle 61 and the left baffle 62 to rotate and open, and form a V-shaped opening, and the two ends of the fixed rod 71 will slide to the fixed rod 71 to the vicinity of the impact rod 75, when the right baffle 61 and the left baffle 62 are opened, the right baffle 61 drives the coarse filter 65 to rotate with the lower end of the connecting rod 63 as the center through the connecting rod 64, so that the coarse filter 65 is tilted, and firstly pre-filtering is performed to filter out some large solid impurities, and other diisopropylbenzene hydroperoxide will enter the next process. At the same time, the threaded sleeve 74 drives the impact rod 75 to rotate, and it will continuously hit the inclined rod 76 to cause the cross rod 73 and the fixed rod 71 to deform and shake, thereby driving the coarse filter 65 to produce a certain vibration, which can improve the filtering effect and quickly shake off the debris and discharge it from the opening on one side of the body 1;

The double-layer high-toughness filter 83 can ensure the filtering effect and improve the quality. At the same time, when the high-toughness filter 83 rotates, the filtering rate can be increased, and the work efficiency can be improved. Then it will be discharged from the transport pipe 3 and enter the next process;

[0043] S4. Before that, when the driven roller 82 rotates, it drives the eccentric shaft 91 to rotate. When the eccentric shaft 91 rotates, it drives the connecting rod 1 92, and the round rod 95 pushes or pulls the rotating tooth 94 to swing back and forth with the rotating rod 93 as the center, so as to clean the side of the high-toughness filter screen 83, prevent the surface of the high-toughness filter screen 83 or the residual debris in the gap, which can improve the filtering effect. At the same time, when the eccentric shaft 91 rotates, it also drives the knocking rod 97 to rotate. When the knocking rod 97 rotates, it will continuously hit the vibration rod 96 in the driven roller 82 to vibrate, so as to make the driven roller 82 vibrate. When the driven roller 82 vibrates, it will drive the entire high-toughness filter screen 83 to vibrate, which further improves the filtering efficiency.

[0044] S5. Finally, at the end, the driving motor 41 is stopped and the resetting electric rotating rod 54 is started to drive the eccentric gear 57 to rotate in the opposite direction, so that the extension rod 59 moves upward, thereby resetting all the mechanisms and returning to the initial state.

5. The method for preparing a diisopropylbenzene hydroperoxide preparation device according to claim 4, characterized in that: The following steps are involved: S1. First, the raw material is pretreated and then oxidized, and then the concentrated semi-finished product diisopropylbenzene hydroperoxide and the diatomaceous earth filter are injected into the mixing box body (2) and started, and then the driving motor (41) is started. The driving motor (41) drives the telescopic stirring rod (42) to rotate in the mixing box body (2), and drives the stirring blade (43) to rotate to stir and mix. When the telescopic stirring rod (42) rotates, the annular rotating rod (51) at the upper end is driven to rotate. When the annular rotating rod (51) rotates, the intermittent wheel (53) is driven to rotate slowly. The intermittent wheel (53) rotates in the mixing box body (2) through the telescopic rod (52). When the intermittent wheel (53) rotates, the side rotating rod (55) is driven to rotate slowly. When the rotating rod (55) rotates, the eccentric gear (57) is driven to rotate. When the eccentric gear (57) rotates, the meshing gear (58) rotates, and when the gear (58) rotates, it drives the eccentrically rotating extension rod (59) to gradually slide downward in the U-shaped frame (56). When the extension rod (59) slides downward, it drives the L-shaped rod (513) at the lower end to move downward. The L-shaped rod (513) drives the telescopic stirring rod (42) to gradually extend. At the same time, when the telescopic stirring rod (42) is about to drop to the bottom, the extension rod (59) drives the side extrusion rod (512) to slide downward and squeeze the inclined surface of the inclined rod (511). The inclined rod (511) will slide to the right inside the limiting slide groove (510). At the same time, the inclined rod (511) drives the entire intermittent wheel (53) to slide on the telescopic rod (52) and slide on the surface of the rotating rod (55). At this time, the intermittent wheel (53) will separate from the annular rotating rod (51), and the telescopic stirring rod (42) will continue to rotate; S2. When the telescopic stirring rod (42) is gradually extended, the hinged rod (44) is driven to move downward at the same time. The hinged rod (44) first enters the threaded sleeve (74), drives the threaded sleeve (74) to rotate, and squeezes the cross rod (73) through the threaded sleeve (74). When the cross rod (73) is squeezed, it squeezes the fixed rod (71) at the same time. The fixed rod (71) drives the right baffle (61) and the left baffle (62) to open relative to each other. At the same time, the cross rod (73) slides in the sliding groove (72) provided in the fixed rod (71). At this time, the cross rod (73) is continuously squeezed, driving the right baffle (61) and the left baffle (62) to rotate and open, and presents The V-shaped opening is formed, and the two ends of the fixed rod (71) slide to the fixed rod (71) to a position close to the impact rod (75). When the right baffle (61) and the left baffle (62) are opened, the right baffle (61) drives the coarse filter (65) to rotate with the lower end of the connecting rod (63) as the center of the circle through the connecting rod (64), so that the coarse filter (65) is tilted, and pre-filtration is first performed. Diisopropylbenzene hydroperoxide will enter the next process. At the same time, the threaded sleeve (74) drives the impact rod (75) to rotate, and it will continuously impact the inclined rod (76), so that it drives the cross rod (73) and the fixed rod (71) to deform and shake, and then discharged from the opening on one side of the machine body (1); S3, the semi-finished product diisopropylbenzene hydroperoxide will enter the surface of the high-toughness filter screen (83), and at the same time, the high-toughness filter screen (83) will continue to operate through the active electric roller (81) and the driven roller (82). The double-layer high-toughness filter screen (83) can ensure the filtering effect. At the same time, when the high-toughness filter screen (83) rotates, the filtering rate can be increased, and then it will be discharged from the transport pipe (3) and enter the next process; S4. Prior to this, when the driven roller (82) rotates, it drives the eccentric shaft (91) to rotate. When the eccentric shaft (91) rotates, it drives the connecting rod (92) to push or pull the rotating tooth (94) through the round rod (95) to reciprocate around the rotating rod (93). At the same time, when the eccentric shaft (91) rotates, it drives the knocking rod (97) to rotate. When the knocking rod (97) rotates, it continuously strikes the vibration rod (96) in the driven roller (82), causing it to vibrate, thereby causing the driven roller (82) to vibrate. When the driven roller (82) vibrates, it drives the entire high-toughness filter screen (83) to vibrate. S5. Finally, at the end, the driving motor (41) is stopped and the resetting electric rotating rod (54) is started to drive the eccentric gear (57) to rotate in the opposite direction, so that the extension rod (59) moves upward, thereby resetting all the mechanisms and returning to the initial state.
