Description

Technical Field

[0001] This utility model relates to the field of isooctane fractionation towers, specifically a side extraction hopper for isooctane reactors. Background Technology

[0002] Isooctane is an ideal high-octane gasoline blending component with an octane number of 95-98, low vapor pressure, high calorific value and combustion efficiency, and is miscible with water in any proportion.

[0003] In existing technologies, the production process of isooctane mainly uses concentrated sulfuric acid alkylation. The vertical isooctane fractionation tower, which relies on isobutane vaporization for heat extraction, mainly includes a dispersion zone, a reaction zone, a vaporization zone, and a collection zone. Most of the unreacted isobutane is vaporized endothermally and then extracted from the gas phase outlet of the vaporization zone. The gas phase outlet usually contains a small amount of acid, which can easily cause damage to this location and requires regular cleaning and maintenance. However, the gas phase outlet is usually located in the middle of the tower, making it inconvenient to disassemble quickly. Based on this, this utility model proposes a side extraction hopper for isooctane reactors. Utility Model Content

[0004] The purpose of this invention is to provide a side extraction hopper for an isooctane reactor in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a side extraction hopper for an isooctane reactor, comprising a middle section of a fractionation tower and a side extraction hopper inserted into the side wall of the middle section of the fractionation tower. The side extraction hopper is equipped with a filter screen for filtering the exhaust gas discharged during the isooctane gas production process on one side of the side inside the middle section of the fractionation tower. The side extraction hopper is provided with a limiting mechanism for limiting the middle section of the fractionation tower and the side extraction hopper.

[0006] The limiting mechanism includes a limiting unit and a transmission unit, and the number of the limiting units is two.

[0007] The limiting unit is used to provide a limit for the connection of the middle and side extraction hoppers of the fractionation tower;

[0008] The transmission unit is used to synchronously drive the two limit units to move.

[0009] As a further embodiment of this utility model: the transmission unit includes a pull rod, a movable block, a spring, a connecting rod, and a movable groove;

[0010] The outer wall of the arc-shaped plate of the side extraction bucket has integrally formed outwardly protruding sleeves at both the upper and lower ends. The movable groove is vertically opened inside the arc-shaped plate of the side extraction bucket. The connecting rod is slidably installed on the inner wall of the movable groove. Movable blocks are fixedly installed at both the upper and lower ends of the connecting rod. The pull rod is axially slidably installed inside the lower sleeve and extends to the outside of the sleeve. The pull rod in the moving state is used to drive the movable block located below to move synchronously.

[0011] The lower movable block is fixed to one end of the pull rod and slidably installed inside the sleeve of the side extraction bucket. In the moving state, the lower movable block is used to synchronously drive the connecting rod and push rod connected to its other end to move in the same direction.

[0012] The two ends of the spring are respectively engaged with one end of the inner wall of the sleeve of the side extraction bucket and one end of the movable block located below. The spring is used to drive the movable block to return to its original position after it has been moved.

[0013] As a further embodiment of this utility model: the limiting unit includes a push rod, a guide rod, a limiting block, and a guide groove;

[0014] The push rod is fixed to the ends of the two movable blocks and extends to the inner side of the limiting block. The push rod provides a squeezing force to the guide groove through the guide rod fixed to the outer wall.

[0015] The limiting block is vertically slidably installed inside the side extraction hopper and extends into the interior of the middle part of the fractionation tower. The limiting block is used to limit the connection between the middle part of the fractionation tower and the side extraction hopper.

[0016] The guide groove is formed on the inner side of the limiting block and is movably connected to the guide rod. The guide groove is used to transmit the squeezing force from the guide rod to the limiting block.

[0017] As a further improvement of this utility model: the guide groove is inclined as a whole, and the inner side of the guide groove matches the outer wall of the guide rod.

[0018] As a further improvement of this utility model: the number of the limiting blocks is set to two, and the two limiting blocks are symmetrically distributed in the two sleeve parts of the side extraction bucket. The middle part of the distillation tower is formed with a limiting groove for the insertion of the limiting blocks.

[0019] As a further improvement of this utility model: the upper and lower ends of the connecting rod are L-shaped, and the position where the connecting rod overlaps with the extraction pipe on the arc plate of the side extraction bucket is semi-circular.

[0020] As a further improvement of this utility model: the interior of the side extraction hopper is formed with a sliding groove for the axial movement of the movable block, and a sealing ring is provided at the connection between the middle part of the distillation tower and the side extraction hopper.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By setting a limiting mechanism, when it is necessary to clean the side extraction hopper, the pull rod can be pulled outward to drive the movable block and push rod to move outward. The guide rod on the push rod will exert a squeezing force on the guide groove on the limiting block. At the same time, the connecting rod will drive another movable block to move, so that the two symmetrical limiting blocks move closer to each other, thereby releasing the limiting in the middle of the side extraction distillation tower, which will facilitate the quick cleaning of the filter screen on the side extraction hopper.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4 In this embodiment of the present invention, a side extraction hopper for an isooctane reactor includes a middle section 1 of a fractionation tower and a side extraction hopper 2 inserted into the side wall of the middle section 1 of the fractionation tower. The side extraction hopper 2 is equipped with a filter screen 3 for filtering the exhaust gas discharged during the isooctane gas production process on one side of the middle section 1 of the fractionation tower. The side extraction hopper 2 is provided with a limiting mechanism 4 for limiting the middle section 1 of the fractionation tower and the side extraction hopper 2.

[0030] The limiting mechanism 4 includes a limiting unit and a transmission unit, and the number of limiting units is two;

[0031] The limiting unit is used to limit the connection between the middle section 1 and the side extraction hopper 2 of the distillation tower;

[0032] The transmission unit is used to synchronously drive the two limit units to move;

[0033] The transmission unit includes a pull rod 401, a movable block 402, a spring 403, a connecting rod 408, and a movable groove 409;

[0034] The outer wall of the arc-shaped plate of the side extraction bucket 2 has an integrally formed sleeve portion protruding outward at both the upper and lower ends. The movable groove 409 is vertically opened inside the arc-shaped plate of the side extraction bucket 2. The connecting rod 408 is slidably installed on the inner wall of the movable groove 409. Movable blocks 402 are fixedly installed at both the upper and lower ends of the connecting rod 408. The pull rod 401 is axially slidably installed inside the lower sleeve portion and extends to the outside of the sleeve portion. The pull rod 401 in the moving state is used to drive the movable block 402 located below to move synchronously.

[0035] The lower movable block 402 is fixed to one end of the pull rod 401 and is slidably installed inside the sleeve of the side extraction bucket 2. In the moving state, the lower movable block 402 is used to synchronously drive the connecting rod 408 and the push rod 404 connected to its other end to move in the same direction.

[0036] The two ends of the spring 403 are respectively engaged with one end of the inner wall of the sleeve of the side extraction bucket 2 and one end of the lower movable block 402. The spring 403 is used to drive the movable block 402 to reset after it has been moved.

[0037] The limiting unit includes a push rod 404, a guide rod 405, a limiting block 406, and a guide groove 407;

[0038] The push rod 404 is fixed to the ends of the two movable blocks 402 and extends to the inner side of the limiting block 406. The push rod 404 provides the guide groove 407 with a squeezing force through the guide rod 405 fixed to the outer wall.

[0039] The limiting block 406 is vertically slidably installed inside the side extraction hopper 2 and extends into the interior of the middle section 1 of the fractionation tower. The limiting block 406 is used to limit the connection between the middle section 1 of the fractionation tower and the side extraction hopper 2.

[0040] The guide groove 407 is formed inside the limiting block 406 and is movably connected to the guide rod 405. The guide groove 407 is used to transmit the extrusion force from the guide rod 405 to the limiting block 406.

[0041] In this embodiment: With this structure, when the filter screen 3 needs cleaning or replacement, applying an outward pulling force to the pull rod 401 causes the movable block 402 to move outward synchronously. The moving movable block 402 exerts a compressive force on the spring 403. Simultaneously, the push rod 404 and connecting rod 408 fixed at one end of the movable block 402 also move in the same direction. The moving connecting rod 408 synchronously pulls the movable block 402 connected at the other end, causing the two symmetrically distributed movable blocks 402 and push rod 404 to move in the same direction. The moving push rod 404 synchronously drives the guide rod 405 fixed on the outer wall to move, causing the guide rod 405 to exert a compressive force on the inner side of the guide groove 407. The guide groove 407 is pushed by the guide rod 405 and transmits the force to the limiting block 406, causing the limiting blocks 406 to move closer to each other under the push of the guide rod 405 until the limiting blocks 406 move out of the limiting groove on the inner wall of the middle part 1 of the fractionation tower. At this time, the side extraction bucket 2 loses the limitation of the limiting block 406. Under the continuous outward pulling force of the pull rod 401, the side extraction bucket 2 will receive the pulling force from the pull rod 401 and separate from the middle part 1 of the fractionation tower. This achieves the purpose of simultaneously releasing the two limiting blocks 406 from limiting the middle part 1 of the fractionation tower and the side extraction bucket 2, which facilitates the quick removal of the side extraction bucket 2 to clean the filter screen 3 and further improves the work efficiency.

[0042] Please refer to this carefully. Figures 1-4 The guide groove 407 is inclined, and the inner side of the guide groove 407 matches the outer wall of the guide rod 405. There are two limiting blocks 406, which are symmetrically distributed inside the two sleeves of the side extraction hopper 2. The interior of the middle part 1 of the distillation tower is formed with a limiting groove for the insertion of the limiting blocks 406. The upper and lower ends of the connecting rod 408 are L-shaped. The position where the connecting rod 408 overlaps with the extraction pipe on the arc plate of the side extraction hopper 2 is semi-circular. The interior of the side extraction hopper 2 is formed with a sliding groove for the axial movement of the movable block 402. A sealing ring is provided at the connection between the middle part 1 of the distillation tower and the side extraction hopper 2.

[0043] In this embodiment: With this structure, under the action of the guide groove 407, when the guide rod 405 applies a squeezing force to the guide groove 407, the limiting block 406 is subjected to the squeezing force and moves vertically, while the guide rod 405 moves relative to the inner side of the guide groove 407.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
