DETAILED DESCRIPTION
[0037] The three embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0038] First embodiment:
[0039] Figures 1-3 A device for efficiently removing styrene polymerization inhibitors is shown, comprising a purification tank 1, the bottom of the purification tank 1 is provided with a feed pipe 4, the inner wall of the purification tank 1 is fixed with a liquid storage box at a position close to the bottom, the top of the liquid storage box is uniformly penetrated and installed with a plurality of high-pressure nozzles 5, the inner wall of the purification tank 1 is fixedly installed with a lower feed plate 6, a plurality of shaft rods are rotatably connected inside the lower feed plate 6, and the two ends of each shaft rod are connected with the inner wall of the purification tank 1 through a reset damping pivot, the top of each shaft rod is installed with a shaking plate 9, the inner wall of the purification tank 1 is embeddedly installed with an upper discharge plate 7, and the inner parts of the upper discharge plate 7 and the lower feed plate 6 are respectively penetrated and installed with one-way pipes in opposite directions;
[0040] A perforated plate 8 with built-in through holes is installed below the upper discharge plate 7, a large filler ball is arranged between the perforated plate 8 and the upper discharge plate 7, and a small filler ball is arranged between the perforated plate 8 and the lower feed plate 6.
[0041] Figures 4-6 The bottom of each shaft rod is symmetrically connected with a C-shaped lever 91, the inside of the lower feed plate 6 is provided with a channel matched with the lever 91, the inside of the lower feed plate 6 is laid with a movable strip plate 92 with internal holes, and the cross-sectional width of the movable strip plate 92 is less than the horizontal distance between adjacent two shaft rods.
[0042] The diameter and arrangement position of the holes in the movable strip plate 92 are the same as those of the one-way pipes inside the lower feed plate 6, the one-way pipes on the surface of the lower feed plate 6 correspond one-to-one with the high-pressure nozzles 5, and the diameter of the one-way pipes is greater than that of the high-pressure nozzles 5.
[0043] Figures 1-2 A suction pump 2 is installed on the top of the purification tank 1, the input end of the suction pump 2 is connected with a liquid inlet pipe, the tail end of the liquid inlet pipe is connected with two branch pipes, one tail end of the branch pipes is attached to the top surface of the upper discharge plate 7, the tail end of the other branch pipe is slidably penetrated and extends above the lower feed plate 6, and the output end of the suction pump 2 is connected with a discharge pipe.
[0044] Specifically, when the removal of the polymerization inhibitor is performed, the styrene solution entering the purification tank 1 through the feed pipe 4 is sprayed upward by the high-pressure spray head 5. Since the high-pressure spray head 5 corresponds to the one-way pipe on the surface of the lower feed plate 6, the liquid sprayed by the high-pressure spray head 5 flows upward in one direction. Even if the sprayed liquid cannot be sprayed to the height of the large filler ball due to insufficient momentum and naturally falls, it is intercepted by the lower feed plate 6, immersed in the small filler ball, and then transferred to the upper part of the purification tank 1 through another branch pipe. After passing through the small filler ball, the large filler ball, and the upper discharge plate 7, the liquid is transferred to the upper part of the upper discharge plate 7 in one direction, and then transferred to the upper part of the purification tank 1 through one of the branch pipes.
[0045] Figures 7-8 As shown, during the process, the uniform feed of the styrene solution can be achieved by the uniformly distributed high-pressure spray head 5, and the top discharge can reduce the occurrence of bias flow. The small filler ball and the large filler ball made of aluminum oxide ball material are stacked from bottom to top, so that the sprayed liquid first passes through the small filler ball area with high density, thereby achieving the initial speed reduction of the sprayed liquid. At the same time, the reciprocating movement of the swing plate 9 is driven by the pulling rod 32, so as to extrude the small filler ball and improve the density of the small filler ball area, so that the liquid passing through the small filler ball can be further slowed down, thereby improving the removal efficiency of the polymerization inhibitor and prolonging the removal efficiency of the polymerization inhibitor.
[0046] When the swing plate 9 extrudes the small filler ball, the small filler ball in each adjacent independent area will be extruded, and at the same time, the lifting bar 91 lifts the movable strip plate 92, so that the adsorption position of the small filler ball is in dynamic change, thereby fully achieving the adsorption and removal effect.
[0047] The outer surface of the purification tank 1 is provided with a driving motor 3, the output end of the driving motor 3 is connected with a gear ring 31, the lower part of the gear ring 31 is connected with a driving rack 33 in a meshing manner, one end of the driving rack 33 is connected with a pulling rod 32 slidingly penetrating the inside of the purification tank 1, and the pulling rod 32 is fixedly penetrated into the inside of a plurality of swing plates 9.
[0048] Specifically, when the swing plate 9 needs to be swung, the driving motor 3 can be started, and by forward and reverse rotation, the reciprocating movement of the pulling rod 32 is driven by the meshing action of the driving rack 33 and the gear ring 31, thereby driving the reciprocating swing of the swing plate 9.
[0049] The bottom of the perforated plate 8 is connected with a net 81, and the small filler ball is located in the inside of the net 81, and the bottom of the net 81 is located above the movable strip plate 92.
[0050] Specifically, the top edge of the perforated plate 8 is connected with the bottom edge of the upper discharge plate 7 by a surrounding net, when the small filler balls and the large filler balls need to be replaced due to adsorption saturation, the upper discharge plate 7 and the perforated plate 8 are taken out together from the inside of the purification tank 1, and due to the design of the surrounding net and the net bag 81, the small filler balls and the large filler balls can be taken out at one time, and falling is avoided.
[0051] A working method of a high-efficiency removal device for a styrene polymerization inhibitor, comprising the following steps:
[0052] S1, filling, small filler balls made of alumina balls are filled into the net bag 81, and the large filler balls are placed in the position between the perforated plate 8 and the upper discharge plate 7;
[0053] S2, feeding, the styrene solution containing the polymerization inhibitor is injected into the purification tank 1 through the feeding pipe 4, and is sprayed upward through the high-pressure spray head 5;
[0054] S3, adsorption and removal, the upwardly sprayed styrene solution passes through the small filler balls and the large filler balls in sequence and is adsorbed, and the styrene solution after adsorption and removal is transferred by the suction pump 2, so that the top discharge operation is realized;
[0055] S31, periodically start the driving motor 3 to make it rotate forward and reverse, drive the pull rod 32 to reciprocate, drive the swing plate 9 to swing, and perform swing extrusion operation on the small filler balls in the net bag 81, so that the upwardly sprayed styrene solution is slowed down when passing through the small filler balls;
[0056] S32, when the swing plate 9 swings, the rocker 91 lifts the movable strip plate 92, and cooperates with the extrusion of the swing plate 9 to lift the small filler balls in the net bag 81, so that the position of the small filler balls in the net bag 81 is switched.
[0057] Second embodiment:
[0058] Figures 9-10 It is shown that the bottom of the perforated plate 8 is connected with a plurality of limiting blocks 82, and the limiting blocks 82 are distributed on both sides of the swing plate 9 in pairs, the surface of the large filler ball is arranged with a strip-shaped pattern, the top surface of the perforated plate 8 is arranged with a follower piece 83, and the follower piece 83 is located in the middle of the two through holes, one side surface of the follower piece 83 is a smooth surface 831, and the other side surface of the follower piece 83 is a rough surface 832.
[0059] The projections of the two follower pieces 83 on both sides of the through hole of the surface of the perforated plate 8 in the vertical direction do not have overlapping areas in the lying state of the follower pieces 83.
[0060] When the swing plate 9 moves close to the driving motor 3, the rough surface 832 is upward, and when the swing plate 9 moves away from the driving motor 3, the smooth surface 831 is upward.
[0061] Different from the first embodiment, in the present embodiment, the diameter of the perforated plate 8 is smaller than the upper discharge plate 7 and the lower feeding plate 6, and the distance between the edge of the perforated plate 8 and the inner wall of the purification tank 1 is smaller than the diameter of the large filler ball. The shaking plate 9 drives the perforated plate 8 to swing, so as to change the position of the large filler ball, further improve the adsorption and removal effect of the large filler ball. In addition, the top end of the shaking plate 9 is in abutting contact with the bottom of the perforated plate 8, and the follower sheet 83 is made of elastic material.
[0062] Specifically, when the shaking plate 9 swings, it is intercepted by the limiting block 82, which can limit the swing amplitude of the perforated plate 8 driven by the limiting block 82, so as to avoid excessive swing of the shaking plate 9 impacting the inner wall of the purification tank 1.
[0063] Since there is a gap between the perforated plate 8 and the inner wall of the purification tank 1, the perforated plate 8 can smoothly swing when following the shaking plate 9;
[0064] Figure 11 As shown, when the perforated plate 8 swings, when it moves in the direction close to the driving motor 3, the rough surface 832 is upward, and the friction between the rough surface 832 and the strip-shaped pattern on the surface of the large filler ball makes the large filler ball deflect slightly. When it moves in the direction away from the driving motor 3, the smooth surface 831 is upward, and the friction between the strip-shaped pattern on the surface of the large filler ball and the smooth surface 831 is not enough to drive the large filler ball to deflect, so as to avoid the reset of the large filler ball after single deflection. Through multiple deflection adjustments, the adsorption position of the large filler ball can be adjusted, so as to improve the adsorption sufficiency.
[0065] Third embodiment:
[0066] Different from the second embodiment, in the present embodiment, in order to ensure the flattening effect of the follower sheet 83 when following the movement of the perforated plate 8, a displacement sensor and an electromagnetic device with two working states are added in the perforated plate 8, and a magnetic layer different from the magnetic layer on the surface of the follower sheet 83 is coated on the surface of the follower sheet 83. When the perforated plate 8 moves to the right, the electromagnetic device and the magnetic layer on the smooth surface 831 of the follower sheet 83 are attracted to each other, so that the rough surface 832 is upward. Similarly, when the perforated plate 8 moves to the left, the electromagnetic device switches the working state and the magnetic layer on the rough surface 832 is attracted to each other, so that the smooth surface 831 is upward.
[0067] In summary, the present application can realize uniform feeding of styrene through the high-pressure nozzle 5, and can realize top discharge by cooperating with the lower feeding plate 6, the upper discharging plate 7 and the suction pump 2. In addition, the styrene solution containing the polymerization inhibitor is subjected to two rounds of speed reduction operation through the cooperation of the shaking plate 9, the plurality of lever rods 91 and the moving strip plate 92, so as to prolong the duration of the removal of the polymerization inhibitor, save the cost and improve the product quality. In addition, the shaking of the follower plate 83 and the shaking plate 9 drives the position change of the large filler balls and the small filler balls, realizes the full adsorption of the large filler balls and the small filler balls, prolongs the duration of the replacement of the filler and reduces the replacement frequency of the filler.
[0068] In combination with the actual needs, the above-mentioned embodiments of the present application are not limited to the scope, and various changes made within the knowledge of those skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
