DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] Example: Reference Figure 1-Figure 15A cracking reaction system with controllable reaction time includes a circular base frame 101, on which a partition component, an auxiliary component, and a temperature control component are arranged, the partition component includes a cross circular plate 110, eight position-limiting long rods 106 are fixedly arranged in a circular array on the circular base frame 101, and the cross circular plates 110 are all slidably matched with the position-limiting long rods 106, an auxiliary screw rod 105 is rotatably installed on the circular base frame 101, and the auxiliary screw rod 105 and the cross circular plate 110 form a spiral pair, An auxiliary motor 104 is fixedly installed on the circular base frame 101, and the output shaft of the auxiliary motor 104 is fixedly connected to the auxiliary screw 105. Four fan-shaped expansion plates 109 are slidingly installed in a circular array on the cross circular plate 110. An expansion unit is arranged between the four fan-shaped expansion plates 109. The fan-shaped expansion plates 109 are each provided with two through holes that cooperate with the limiting long rod 106. The limiting long rod 106 is used to assist in limiting the position between the fan-shaped expansion plate 109 and the cross circular plate 110.

[0032] The unfolding unit includes an annular support plate 103 fixedly mounted on a circular base frame 101, and four unfolding racks 111 are slidably mounted in a circular array on the annular support plate 103. The ends of the unfolding racks 111 closest to the axis of the annular support plate 103 are fixedly provided with unfolding bars 112. The fan-shaped unfolding plates 109 are provided with grooves that cooperate with the unfolding bars 112. The unfolding bars 112 are used to adjust the position of the fan-shaped unfolding plates 109. A gear set is provided between the four unfolding racks 111, and the gear set includes an unfolding gear ring 113, four The transmission gear 116, four unfolding gears 117, the unfolding gear ring 113 and the four unfolding gears 117 are all rotatably mounted on the annular support plate 103, and the unfolding gears 117 are respectively meshed with the corresponding unfolding racks 111 to form a gear rack pair, and the transmission gears 116 are respectively fixedly mounted on the corresponding unfolding gears 117, and the transmission gears 116 are all meshed with the unfolding gear rings 113 to form a gear pair. An unfolding motor 115 is also fixedly mounted on the annular support plate 103, and the output shaft of the unfolding motor 115 is fixedly connected to the corresponding unfolding gear 117.

[0033] In the initial position, the four fan-shaped expansion plates 109 are all located at the position closest to the axis of the expansion gear ring 113. At this time, there is no gap between the cross circular plate 110 and the four fan-shaped expansion plates 109, that is, a complete circular base plate is formed between the cross circular plate 110 and the four fan-shaped expansion plates 109. The two through holes on the fan-shaped expansion plate 109 are located directly above the corresponding limiting long rod 106, and in the initial position, the cross circular plate 110 is located at the farthest position from the lower surface of the circular base frame 101. At this time, the groove on the fan-shaped expansion plate 109 is in a state of engagement with the corresponding expansion bar 112, and the through hole on the fan-shaped expansion plate 109 is not engaged with the limiting long rod 106.

[0034] At this time, the auxiliary motor 104 is started to drive the auxiliary screw rod 105 to rotate, so that the cross circular plate 110 moves downward, that is, the four fan-shaped expansion plates 109 move downward synchronously, and the through holes on the fan-shaped expansion plates 109 engage with the corresponding limiting long rods 106, and at this time the expansion strips 112 have not yet disengaged from the fan-shaped expansion plates 109, that is, the expansion strips 112 always limit the position of the fan-shaped expansion plates 109 during the engagement of the fan-shaped expansion plates 109 with the limiting long rods 106, the fan-shaped expansion plates 109 continue to move downward, and the expansion strips 112 disengage from the fan-shaped expansion plates 109. At this time, the fan-shaped expansion plates 109 cannot move relative to the cross circular plate 110 under the action of the limiting long rods 106, that is, the position locking between the fan-shaped expansion plates 109 and the cross circular plate 110 is achieved.

[0035] When the cross circular plate 110 is located at the farthest position from the lower surface of the circular base frame 101, the unfolding motor 115 is started to drive the corresponding unfolding gear 117 to rotate, and the corresponding transmission gear 116 rotates synchronously. Under the action of the unfolding gear ring 113, the four transmission gears 116 rotate synchronously, so that the four unfolding gears 117 rotate synchronously, and then the four unfolding racks 111 all move in the direction away from the axis of the unfolding gear ring 113. Under the action of the unfolding bar block 112, the fan-shaped unfolding plates 109 move synchronously, so that the four fan-shaped unfolding plates 109 move in the direction away from the axis of the unfolding gear ring 113, thereby realizing the unfolding of the four fan-shaped unfolding plates 109.

[0036] A partition outer ring plate 107 is fixedly installed on the cross circular plate 110, and a partition inner ring plate 120 is also rotatably installed on the cross circular plate 110. An annular cover plate 114 is slidably installed on the partition inner ring plate 120. A reaction chamber is formed between the partition outer ring plate 107, the fan-shaped expansion plate 109, the annular cover plate 114, and the partition inner ring plate 120. Eight partition partitions 108 are slidably installed in a circular array on the annular cover plate 114. The partition partitions 108 are used to separate the reaction chambers. The eight partition partitions 108 divide the reaction chamber into eight partition chambers, which are used to store materials and catalysts in each reaction stage.

[0037] The temperature control assembly includes four temperature regulating ring plates 102, which are used to control the temperature of the reaction chamber. The four temperature regulating ring plates 102 are evenly fixed on the circular base frame 101. The four temperature regulating ring plates 102 are used for preheating, cracking, constant temperature, and cooling from top to bottom. The temperatures of the preheating stage, cracking stage, constant temperature stage, and cooling stage of the reaction chamber are adjusted respectively by the four temperature regulating ring plates 102.

[0038] A positioning unit is arranged between the eight partition partitions 108, a circular support frame 121 is installed on the inner side of the partition inner ring plate 120, an annular slide 118 is fixedly installed on the annular cover plate 114, the annular slide 118 and the circular support frame 121 are slidably matched, a separation screw rod 119 is rotatably installed on the circular support frame 121, the separation screw rod 119 and the annular slide 118 constitute a spiral pair, a separation motor 134 is fixedly installed on the lower surface of the circular support frame 121, and the output shaft of the separation motor 134 is fixedly connected to the separation screw rod 119.

[0039] In the initial position, the annular slide 118 is located at the position closest to the cross circular plate 110, that is, the annular cover plate 114 is located at the position closest to the cross circular plate 110. At this time, a closed reaction chamber is formed between the partition outer ring plate 107, the fan-shaped expansion plate 109, the cross circular plate 110, the annular cover plate 114, and the partition inner ring plate 120. The separation motor 134 is started to drive the separation screw 119 to rotate, so that the annular slide 118 moves upward and the annular cover plate 114 moves synchronously, that is, the upper end surface of the reaction chamber is opened, thereby facilitating the addition of materials and catalysts to be used into each partition chamber.

[0040] The partition partitions 108 are all fixedly mounted with strip slides 125, which are slidably matched with the circular support frame 121. The positioning unit includes a limiting circular plate 123 and a positioning rotating frame 128 rotatably mounted on the circular support frame 121. The limiting circular plate 123 and the positioning rotating frame 128 are rotatably matched with each other. The ends of the strip slides 125 closest to the axis of the limiting circular plate 123 are provided with sliding grooves that cooperate with the limiting circular plate 123. The limiting circular plate 123 is provided with an arc-shaped notch 124. The arc-shaped notch 124 is used to make way for the movement of the strip slide 125. There is friction between the strip slide 125 and the circular support frame 121. The strip slide 125 cannot slide relative to the circular support frame 121 when no external force is applied.

[0041] In the initial position, the limiting circular plate 123 and the eight strip slides 125 are all in an engaged state. At this time, under the action of the limiting circular plate 123, the strip slide 125 cannot move up and down relative to the circular support frame 121, that is, the partition partition 108 cannot move up and down relative to the circular support frame 121, thereby locking the position of the partition partition 108, driving the limiting circular plate 123 to rotate relative to the circular support frame 121, so that the arc-shaped notch 124 moves to the position of the strip slide 125 corresponding to the partition partition 108 to be adjusted, under the action of the arc-shaped notch 124, the strip slide 125 disengages from the limiting circular plate 123, that is, at this time, the partition partition 108 corresponding to the arc-shaped notch 124 can move up and down relative to the circular support frame 121, and other partition partitions 108 still cannot move up and down relative to the circular support frame 121.

[0042] The circular support frame 121 is also provided with 8 adjusting screw rods 129 rotatably mounted in a circular array. The adjusting screw rods 129 respectively form a spiral pair with the corresponding strip slides 125. The ends of the adjusting screw rods 129 are fixedly mounted with adjusting round blocks 130. The adjusting rotating frame 128 is fixedly provided with fan-shaped strips 131. The adjusting round blocks 130 are provided with sliding grooves that cooperate with the fan-shaped strips 131. The adjusting rotating frame 128 is also provided with fan-shaped strips 133 rotatably mounted. When the fan-shaped strips 131 and the fan-shaped strips 133 are engaged, a complete ring plate is formed. The fan-shaped strips 133 are used to adjust the position of the strip slide 125. A positioning motor 132 is fixedly mounted on the positioning rotating frame 128, and the output shaft of the positioning motor 132 is fixedly connected to the fan-shaped strips 133.

[0043] In the initial position, the adjusting circular blocks 130 are in engagement with the fan-shaped strips 131, that is, under the action of the limiting circular plate 123 and the fan-shaped strips 131, the position of the partition partition 108 is double fixed, thereby preventing the partition partition 108 from moving when the materials and catalysts are stored in the partition chamber, causing the materials and catalysts to react prematurely.

[0044] When the arc-shaped notch 124 moves to the position of the strip slide 125 corresponding to the partition partition 108 to be moved, the adjustment rotating frame 128 is driven to rotate relative to the circular support frame 121, and the fan-shaped strips 131 and the fan-shaped strips 133 rotate synchronously, so that the fan-shaped strips 133 engage with the adjustment round block 130 corresponding to the partition partition 108. At this time, the axis of the adjustment round block 130 and the axis of the adjustment motor 132 are in the same straight line. Then the adjustment motor 132 is started to drive the fan-shaped strip 133 to rotate, that is, the adjustment round block 130 rotates, and then the adjustment screw rod 129 rotates. Under the action of the adjustment screw rod 129, the strip slide 125 moves upward, that is, the partition partition 108 moves downward, and finally the partition partition 108 moves to the position farthest from the cross circular plate 110. At this time, the lower end surface of the partition partition 108 and the lower surface of the annular cover plate 114 are in the same plane.

[0045] A second adjusting ratchet 136 is fixedly mounted on the limiting circular plate 123, a first adjusting ratchet 135 is fixedly mounted on the adjusting rotating frame 128, the rotation directions of the first adjusting ratchet 135 and the second adjusting ratchet 136 are opposite, a second transmission ratchet 138 is also rotatably mounted on the circular support frame 121, a first transmission ratchet 137 is fixedly mounted on the second transmission ratchet 138, the rotation directions of the first transmission ratchet 137 and the second transmission ratchet 138 are opposite, a ratchet mechanism 1 is formed between the first adjusting ratchet 135 and the first transmission ratchet 137, and a ratchet mechanism 2 is formed between the second adjusting ratchet 136 and the second transmission ratchet 138, a switching motor 122 is fixedly mounted on the upper surface of the circular support frame 121, and the output shaft of the switching motor 122 is fixedly connected to the second transmission ratchet 138.

[0046] The switching motor 122 is started to drive the transmission ratchet wheel 138 to rotate, and the transmission ratchet wheel 137 rotates synchronously. Under the action of the positioning ratchet wheel 135, the positioning ratchet wheel 136, the transmission ratchet wheel 137 and the transmission ratchet wheel 138, when the transmission ratchet wheel 138 drives the positioning ratchet wheel 136 to rotate, the transmission ratchet wheel 137 rotates relative to the positioning ratchet wheel 135. When the transmission ratchet wheel 137 drives the positioning ratchet wheel 135 to rotate, the transmission ratchet wheel 138 rotates relative to the positioning ratchet wheel 136, thereby realizing the respective adjustment of the positions of the limiting circular plate 123 and the fan-shaped strip plate 131.

[0047] The auxiliary component includes 8 U-shaped stirring plates 127 rotatably mounted on the partition inner ring plate 120 in a circular array. The U-shaped stirring plates 127 and the partition partition plate 108 are spaced apart. A friction wheel 141 is fixedly mounted on the end of the U-shaped stirring plate 127 closest to the axis of the partition inner ring plate 120. An annular friction plate 140 is fixedly mounted on the cross circular plate 110. There is friction between the annular friction plate 140 and the friction wheel 141.

[0048] A circular rotating plate 139 is also rotatably installed on the cross circular plate 110. Four connecting rods are arranged between the circular rotating plate 139 and the circular support frame 121. The circular support frame 121 and the circular rotating plate 139 are fixedly connected by the connecting rods. The axes of the partition outer ring plate 107, the partition inner ring plate 120, the circular support frame 121 and the circular rotating plate 139 are on the same straight line. A circulating motor 126 is fixedly installed on the lower surface of the cross circular plate 110, and the output shaft of the circulating motor 126 is fixedly connected to the circular rotating plate 139.

[0049] Start the circulation motor 126 to drive the circular rotating plate 139 to rotate, and the partition inner ring plate 120 and the circular support frame 121 rotate synchronously, thereby causing the partition partition 108 and the annular cover plate 114 to rotate synchronously, and the U-shaped stirring plate 127 on the partition inner ring plate 120 also rotates synchronously, and the friction wheel 141 on the U-shaped stirring plate 127 rotates relative to the annular friction plate 140. Under the action of the annular friction plate 140, the friction wheel 141 rotates on its own, causing the U-shaped stirring plate 127 to rotate on its own.

[0050] Eight air pumps 143 are fixedly installed in a circular array on the partition inner ring plate 120, and eight pressure sensors 142 are also fixedly installed in a circular array on the partition inner ring plate 120. The air pumps 143 and the pressure sensors 142 are spaced apart from the partition partition 108. The air pumps 143 are used to adjust the pressure of the corresponding partition chamber, and the pressure sensors 142 are used to monitor the pressure of the corresponding partition chamber.

[0051] Working principle: According to the preset amount of material to be reacted, the volume of the partition chamber storing the material is adjusted by the positioning unit. After the volume of each partition chamber is adjusted, the separation motor 134 is started to drive the annular cover 114 and the annular slide 118 to move upward synchronously, so that the annular cover 114 moves to the position farthest from the cross circular plate 110, and then the specified material or catalyst is added to each chamber. The catalyst is stored in the chamber next to the partition chamber containing the reaction material in the order of use. After the addition is completed, the annular slide 118 returns to the initial position.

[0052] Then, the auxiliary motor 104 is started to move the cross circular plate 110 downward, and the reaction chamber moves downward synchronously. The fan-shaped expansion plate 109 and the limiting long rod 106 are engaged. The auxiliary screw rod 105 and the limiting long rod 106 are both located on the outside of the partition outer ring plate 107, that is, the auxiliary screw rod 105 and the partition outer ring plate 107 will not affect the movement of the reaction chamber. The reaction chamber is first moved to the position of the temperature regulating ring plate 102 farthest from the lower surface of the circular bottom frame 101, and the interior of the reaction chamber is preheated by the temperature regulating ring plate 102, and the temperature is adjusted according to the temperature. The pressure in the partition chamber is adjusted by the air pump 143 according to the pressure demand, the pressure change in the partition chamber is monitored by the pressure sensor 142, and the circulation motor 126 is started to drive the partition partition 108, the annular cover plate 114, and the partition inner ring plate 120 to rotate synchronously, so that the material and catalyst in the partition chamber rotate relative to the partition outer ring plate 107, the fan-shaped expansion plate 109, and the cross circular plate 110, and under the action of the auxiliary components, the reacting material in the partition chamber is stirred, thereby improving the reaction effect.

[0053] When a certain catalyst needs to be added after heating to a specified temperature, the partition partition 108 between the partition chamber containing the catalyst and the partition chamber containing the reaction material is moved to the position farthest from the cross circular plate 110 through the adjustment unit, so that the catalyst and the reaction material are in contact, and under the action of the U-shaped stirring plate 127, the catalyst and the reaction material are mixed.

[0054] Repeat the above steps to move the reaction chamber downward through each temperature regulating ring plate 102 in turn for cracking reaction. According to the demand, the time for the reaction chamber to stay on the required temperature regulating ring plate 102 is controlled so that the material in the reaction chamber can reach the optimal reaction time. After the four temperature regulating ring plates 102 complete the processing of the reaction chamber, the cross circular plate 110 is moved to the position farthest from the lower surface of the circular base frame 101, and then the four fan-shaped expansion plates 109 are moved to the farthest positions through the expansion unit, and the material in the reaction chamber falls from the lower end surface of the reaction chamber.

[0055] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
