Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical engineering and catalysis technology, and specifically relates to a plasticizer catalytic device. Background Technology
[0002] Plasticizers, as key modifiers for polymers such as plastics and rubber, have a global annual demand exceeding ten million tons. Traditional production processes generally employ homogeneous catalytic systems (such as sulfuric acid and p-toluenesulfonic acid) for esterification reactions. Existing reaction equipment mostly uses batch reactors or fixed-bed designs. Through reactor structural innovation and process integration, mass and heat transfer bottlenecks can be overcome, improving catalytic efficiency and sustainability. The rise of microchannel reactors, fluidized bed catalytic systems, and intelligent control technologies has provided new ideas for the high efficiency, continuous production, and cleanliness of plasticizer production, driving the industry towards low energy consumption, low emissions, and high added value.
[0003] Plasticizers need to be pretreated before catalysis. This step usually requires a separate pretreatment equipment. However, this method will cause time delays and energy losses during material transfer, affecting production efficiency and economic benefits, and increasing production and maintenance costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is that existing equipment is difficult to provide independent pre-processing equipment before production, but material transfer will cause time delays and energy loss, affecting production efficiency and economic benefits, and increasing production and maintenance costs.
[0005] The technical solution adopted to solve the above-mentioned technical problems is to provide a plasticizer catalytic device.
[0006] Furthermore, the device includes a catalytic reactor, which has a drive device inside. A fixed box is fixedly connected to the right side of the catalytic reactor, and a discharge device is provided inside the fixed box. A temperature control device is fixedly connected to the left side of the catalytic reactor. A partition is fixedly connected inside the catalytic reactor, and a reserved channel is provided on the top surface of the partition, which penetrates the partition.
[0007] Furthermore, a feed inlet is fixedly connected to the left side of the top surface of the catalytic reactor, and a discharge outlet is fixedly connected to the middle of the bottom surface of the catalytic reactor. Both the feed inlet and the discharge outlet penetrate the catalytic reactor, and a support frame is fixedly connected to the outside of the catalytic reactor.
[0008] The above technical solution divides the catalytic reactor into two layers by means of a partition. With the cooperation of a temperature control device and a discharge device, the upper layer of the catalytic reactor can be used for plasticizer pretreatment, while the lower layer can be used for catalytic reaction. This achieves dual use of one reactor, eliminating the need for separate pretreatment equipment, avoiding time delays and energy losses caused by material transfer, significantly improving production efficiency and economic benefits, and saving production and maintenance costs.
[0009] Furthermore, the driving device includes a first motor, which is located on the right side of the top surface of the catalytic reactor and is fixedly connected to the catalytic reactor. A first drive gear is fixedly connected to the output end of the first motor. A first transmission gear meshes with the outside of the first drive gear. A drive rod is fixedly connected to the middle of the bottom surface of the first transmission gear.
[0010] Furthermore, the drive rod passes through the partition and is rotatably connected to the partition. Several levers are fixedly connected to the upper part of the drive rod, and the levers are located above the partition. Several stirring blades are fixedly connected to the lower part of the drive rod, and the stirring blades are located below the partition.
[0011] Through the above technical solution, the first motor drives the first drive gear to rotate, thereby driving the first transmission gear and drive rod to rotate, and the drive rod drives the baffle to stir the plasticizer, so as to fully heat it, and the plasticizer is catalyzed by the cooperation of the stirring blades.
[0012] Furthermore, the feeding device includes a second motor, which is fixedly connected to the fixed box. A second drive gear is fixedly connected to the output end of the second motor, and a second transmission gear meshes with the outside of the second drive gear. The second motor, the second drive gear, and the second transmission gear are all located inside the fixed box.
[0013] Furthermore, a threaded rod is fixedly connected to the middle left side of the second transmission gear. The threaded rod passes through the fixed box and the catalytic reactor. A push rod is fixedly connected to the left end of the threaded rod. Several baffles are fixedly connected to the outside of the push rod. The baffles and the reserved channels are correspondingly set.
[0014] Through the above technical solution, the second motor drives the second drive gear to rotate, and the second transmission gear meshed with the second drive gear rotates. The rotation of the second transmission gear drives the threaded rod connected internally to move, which in turn drives the push rod and the baffle to move, so that the reserved channel set on the partition is opened, and the pre-treated plasticizer falls through the reserved channel with the cooperation of the push plate.
[0015] Furthermore, the temperature control device includes a temperature control box, which is located on the left side of the catalytic reactor and is fixedly connected to the catalytic reactor. A first heating coil is fixedly connected to the upper right side of the temperature control box, and a second heating coil is fixedly connected to the lower right side of the temperature control box. Both the first heating coil and the second heating coil are located inside the interlayer of the catalytic reactor.
[0016] The above technical solution uses a temperature control box to control the heating of the first heating coil to pretreat the plasticizer, and a temperature control box to control the heating of the second heating coil to catalyze the plasticizer.
[0017] The beneficial effects of this utility model are as follows:
[0018] This invention features a driving device inside the catalytic reactor, a discharge device on the right side of the reactor, and a temperature control device on the left side. The reactor is divided into two layers by a partition. With the cooperation of the temperature control device and the discharge device, the upper layer of the reactor can be used for plasticizer pretreatment, while the lower layer can be used for catalytic reaction. This achieves dual-purpose operation of the reactor, eliminating the need for separate pretreatment equipment, avoiding time delays and energy losses caused by material transfer, significantly improving production efficiency and economic benefits, and saving production and maintenance costs.

Several stirring blades 206 are fixedly connected to the lower outside of the driving rod 204. The stirring blades 206 are located below the partition 9.
[0026] A fixed box 3 is fixedly connected to the right side of the catalytic reactor 1. The fixed box 3 is equipped with a discharge device 8, which includes a second motor 801.

A threaded rod 804 is fixedly connected to the middle left side of the second transmission gear 803. The threaded rod 804 drives the push rod 805 to move through the threaded engagement with the second transmission gear 803. The threaded rod 804 passes through the fixed box 3 and the catalytic reactor 1. A push rod 805 is fixedly connected to the left end of the threaded rod 804. Several baffles 806 are fixedly connected to the outside of the push rod 805. The baffles 806 are used to cooperate with the reserved channel 10 to allow the plasticizer to fall. The baffles 806 and the reserved channel 10 are set accordingly.
[0027] A temperature control device 4 is fixedly connected to the left side of the catalytic reactor 1. The temperature control device 4 includes a temperature control box 401, which is located on the left side of the catalytic reactor 1 and fixedly connected to it.
