Description

Technical Field

[0002] Reactors are broadly understood as containers for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine, food, etc., and are generally pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc. At present, more reactors with temperature control and heating functions are used. Generally, a heating device and a temperature sensor are set in the reactor body (1). The typical heating method is to use a heating coil, a jacket system or other similar heat transfer system to control the temperature in the reactor through a temperature sensor, which realizes the regulation of the temperature in the reactor to a certain extent.

[0003] The reaction rate of the reactants is related to the temperature required for the reaction to occur. Therefore, in order to improve production efficiency, the temperature needs to be adjusted to the optimal reaction temperature as quickly as possible while ensuring safety.

[0043] The driving member includes an arc-shaped rack 2 705, a driving motor 2 706, a driving gear 2 707 and a conical friction wheel 1 708. The arc-shaped rack 2 705 is sleeved on the top of the annular top plate 2 604, and the driving gear 2 707 is sleeved on the outer wall of the output shaft of the driving motor 2 706. When the driving gear 2 707 rotates, the arc-shaped rack 2 705 meshed with it is driven to rotate synchronously, and the conical friction wheel 1 708 rotates synchronously with the driving gear 2 707; the winding member includes a winding wheel 709, a conical friction wheel 2 710, a center rod 711 and a conical push block 1 712. The winding wheel 709 is coupled to the traction rope 1 710. 03 for winding, the winding wheel 709 and the conical friction wheel 2 710 are both sleeved on the outer wall of the center rod 711, a partition 713 is provided above the center rod 711, the center rod 711 is slidably connected with the partition 713, the conical friction wheel 2 710 is located below the conical friction wheel 1 708, and the generatrix of the conical friction wheel 2 710 is parallel to the generatrix of the conical friction wheel 1 708, the conical push block 1 712 is located on the top of the annular top plate 2 604, when the conical push block 1 712 is angularly displaced, the center rod 711 is pushed to move, and the generatrix of the conical friction wheel 2 710 is driven to fit with the generatrix of the conical friction wheel 1 708;Specifically, the second drive motor 706 is started, and the second drive motor 706 drives the second drive gear 707 to rotate, and the second drive gear 707 drives the meshing arc rack 705 to rotate, and the arc rack 705 drives the second annular top plate 604 to rotate, thereby driving the second heat exchange plate 601 to rotate, and adjusting the second heat exchange plate 601 to a state of misalignment with the first heat exchange plate 501. At the same time, the second annular top plate 604 also drives the conical block to move, so that the conical block is gradually inserted into the center rod. The conical block passes under the center rod 711, and as the conical block passes under the center rod 711, the center rod 711 is lifted up, and the center rod 711 drives the conical friction wheel 2 710 to move, so that the conical friction wheel 2 710 is in close contact with the conical friction wheel 1 708. At this time, the conical friction wheel 2 710 can drive the conical friction wheel 1 708 to rotate synchronously, and at this time, the driving gear 2 707 has been meshed with the last tooth of the arc rack 2 705, so the driving gear 2 707 continues to rotate and will not drive The annular top plate continues to move, which can only drive the conical friction wheel 2 710 to rotate, and the conical friction wheel 2 710 will drive the center rod 711 to rotate, and the center rod 711 will drive the winding wheel 709 to rotate, so that the winding wheel 709 reels the traction rope 1 703, thereby pulling the magnetic suction block 1 701 to move. When the heat exchange plate 1 501 needs to be reset, the control driving gear 2 707 rotates in the opposite direction, so that the conical block moves back, and the conical friction wheel 2 710 will rotate with the conical friction wheel 1 708 is separated, and thus no rotational force is generated on the reel 709. At this time, under the action of the compression spring in the second slide slot 704, the magnetic block 1 701 will automatically reset, thereby pushing the magnetic block 2 702 out of the second slide slot 704, and then the heat exchange plate 2 601 can be pushed to a position where it is dislocated with the heat exchange plate 1 501. At this time, the driving gear 2 707 continues to rotate in the opposite direction, which can drive the heat exchange plate 2 601 to move back to a position where it is simultaneously attached to the heat exchange plate 1 501 and the kettle body 1. ;

[0044] The working principle of the kettle body 1 cooling is as follows: when the reactor is used normally, the heat exchange plate 1 501 and the heat exchange plate 2 601 can be synchronously rotated around the kettle body 1, so that the kettle body 1 can be fully heated, and the hot air can be driven to flow, so that the kettle body 1 can be evenly heated. When the temperature in the kettle body 1 needs to be lowered, the heat exchange plate 2 601 can be controlled to rotate and move to a position displaced with the heat exchange plate 1 501, and then pulled to displace the heat exchange plate 2 601 to a state of splicing with the heat exchange plate 1 501 to form a closed loop. At this time, the heat exchange component can be separated from the kettle body 1 so that there is no direct contact between the two. In this way, the heating source can be quickly separated from the kettle body 1, so that the kettle body 1 can be quickly cooled down, and cold air can be introduced into the cavity 4 at the same time. Since the heat exchange component is already in contact with the inner wall of the outer shell 3 at this time, the cold air will automatically pass through the gap between the heat exchange component and the kettle body 1, so that the cold air can contact the kettle body 1 to the greatest extent, and then the kettle body 1 can be quickly cooled down, the cooling speed can be increased, the heat in the reaction area can be quickly extracted in time, and the performance of the product can be guaranteed.

[0045] The middle piece 8 includes a push plate 801, a traction rope 802 and a pressing unit. Several push plates 801 correspond to the movable plate 602 one by one, and the push plates 801 are slidably connected to the heat exchange plate 601. When the push plates 801 are displaced, the position of the movable plate 602 is changed. An inclined push block 804 is provided on the outside of the push plate 801, and an inclined push block 805 is provided on the outer wall of the movable plate 602. The inclined surface of the inclined push block 804 is fitted with the inclined surface of the inclined push block 805. A traction rope 802 is provided on the top of the push plate 801, and one end of the traction rope 802 passes through the annular top plate 604. The pressing unit is used to control the distance between the top end of the traction rope 802 and the annular top plate 604, and the pressing unit can control the displacement of a single or multiple push plates 801. Specifically, the pressing unit can pull or loosen the traction rope 802. When the traction rope 802 is loosened, At this time, the push plate 801 moves downward under the action of its own gravity, and at the same time, the inclined push block 2 805 on its outer wall will gradually separate from the inclined protrusion 1. At this time, under the action of the deformed return spring 1 606, the movable plate 602 will be driven to move. Since a groove matching the movable plate 602 is provided on the side wall of the push plate 801, it will move into the groove, so that the surface of the movable plate 602 is separated from the kettle body 1, which can reduce the area of ​​the heat exchange plate and the kettle body 1 that fits, and then reduce the heat transfer efficiency to the kettle body 1. At this time, cooling the kettle body 1 can improve the cooling efficiency to a certain extent. This adjustment method is suitable for use when you want to reduce the temperature in the reactor within a small range, which can improve the cooling efficiency to a certain extent, and will not cause excessive temperature change differences per unit time, which meets the use of cooling operations under different conditions.

[0046] The pressing unit includes a connecting rod 806, a second return spring 807, a third annular top plate 808 and a second conical push block 809. The connecting rod 806 is hingedly arranged on the top of the partition 713, and one end of the connecting rod 806 is fixedly connected to the second traction rope 802. The second return spring 807 is located between the connecting rod 806 and the partition 713. The second return spring 807 is used to drive the connecting rod 806 to reset.

When the conical push block 2 809 is displaced, it can move downward according to one end of the connecting rod 806. Specifically, when the position of the push plate 801 needs to be adjusted, the push plate 801 can be started at this time. The drive motor 3 812 is driven to drive the drive gear 3 811 to rotate, and the drive gear 3 811 drives the meshing annular rack 3 810 to rotate, thereby driving the annular top plate 3 808 to rotate, so that the annular top plate 3 808 drives the conical push block 2 809 to move. When the conical push block 2 809 gradually contacts the connecting rod 806, it will squeeze the connecting rod 806, so that one end of the connecting rod 806 is hinged downward, thereby relaxing the traction rope 2 802. Since the arc length of the conical push block 2 809 is greater than the path length between the two farthest connecting rods 806, and the conical push block 2 809 contacts the connecting rod 806 in sequence, the push plate 801 is also displaced in sequence. When one or more movable plates 602 are separated from the kettle body 1, it is only necessary to control the displacement distance of the conical push block 2 809. The operation is simple, fast and convenient.
