Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction kettles, in particular to a chemical reaction kettle which is convenient for adding materials. Background Art

[0002] A chemical reactor is a container used for chemical reactions. Through precise design and configuration, it can achieve functions such as heating, evaporative cooling and mixing under specific process conditions. In the chemical production process, the reactor is a key equipment. Its design rationality, operation convenience and safety directly affect the production efficiency and product quality.

[0003] When adding materials to existing reactors, operators are usually required to add materials from the feed port at the top of the reactor. Since some reactors are relatively high, adding a large amount of materials may cause safety hazards. At the same time, the direct pouring method may also cause material leakage, resulting in waste.

[0004] The existing patent (publication number: CN213824686U) is a feeding device for a chemical reactor, comprising a reactor body, a feeding structure, a material barrel, a material guide sleeve, a rotating shaft, a conflict sleeve, an adjustment structure and a feeding port. The beneficial effects of this utility model are: since the end of the material barrel where the material to be added is stored is engaged with the material guide sleeve, and the side of the material guide sleeve is rotatably connected with a mounting block, the material barrel is fixed by the clamping effect between the mounting block and the material guide sleeve, and the material guide sleeve is rotatably connected to the reactor body through the rotating shaft, so that the user can add materials to the material barrel in advance. When adding materials to the reactor, it is only necessary to rotate the material barrel fixed by the material guide sleeve so that the material barrel is completely turned upside down and rotated until the conflict sleeve conflicts with the feeding port, and the material unloading operation can be carried out. Since the material guide sleeve can be rotated, there is no need for the operator to directly carry the material. At the same time, since the material guide sleeve can be directly aligned with the feeding port, leakage of the material is avoided.

There is also a problem of being unable to uniformly feed materials into the reactor and controlling the feeding speed.

[0006] Therefore, a chemical reaction kettle which is convenient for adding materials is proposed. Utility Model Content

[0031] The intermittent feeding mechanism 7 includes a support frame 71, a motor 72, a turntable 73, a connecting rod 74, a connecting block 75, a movable cylinder 76, a lifting rod 77 and a blocking block 78. The support frame 71 is fixedly connected to the top of the kettle body 1, the motor 72 is bolted to the side wall of the support frame 71, the output end of the motor 72 is connected to the bearing of the support frame 71, the turntable 73 is fixedly connected to the output end of the motor 72, the connecting rod 74 is hinged to the side wall of the turntable 73 and is eccentrically arranged, the connecting block 75 is hinged to the bottom of the connecting rod 74, the movable cylinder 76 is fixedly connected to the bottom of the connecting block 75 and is movably arranged inside the feeding port, the lifting rod 77 is fixedly connected to the bottom of the movable cylinder 76, and the blocking block 78 is fixedly connected to the bottom of the lifting rod 77 and is movably connected to the bottom of the feeding pipe 4.

[0032] Specifically, Figure 5As shown, the stirring mechanism 9 includes a top cover 91, a motor 3 92, a stirring shaft 93 and a stirring impeller 94. The top cover 91 is threadedly connected to the top of the storage hopper 6, the motor 3 92 is bolted to the top of the top cover 91, the stirring shaft 93 is fixedly connected to the output end of the motor 3 92 and is connected to the bearing of the top cover 91, and the stirring impeller 94 is fixedly connected to the bottom of the stirring shaft 93.

[0033] Specifically, Figure 5 As shown, the bottom of the feeding tube 4 is in an umbrella shape, the blocking block 78 is in a conical shape, and the side wall of the blocking block 78 matches the side wall of the bottom of the feeding tube 4.

[0034] Specifically, Figure 5 As shown, a sealing ring 10 is sleeved on the side wall of the movable cylinder 76, and the side wall of the sealing ring 10 is in contact with the feeding pipe 4. The sealing ring 10 is made of rubber.

The feed shaft 82 is fixedly connected to the output end of the second motor 81 and is connected to the bearing of the feed inclined tube 5. The spiral blade 83 is fixedly connected to the side wall of the feed shaft 82.

[0040] When in use, first connect the external power supply to start the motor 2 81. At this time, the feed shaft 82 rotates inside the feed inclined tube 5. As the spiral blades 83 rotate, the raw materials inside the storage hopper 6 can be uniformly transported to the feeding pipe 4, thereby realizing the uniform transportation of the raw materials inside the storage hopper 6 to the inside of the feeding pipe 4.

At this time, the lifting rod 77 drives the blocking block 78 to intermittently move away from the bottom of the feeding pipe 4. In this process, the raw materials inside the feeding pipe 4 intermittently fall from the inside of the feeding pipe 4 into the inside of the kettle body 1. In this way, the raw materials inside the feeding pipe 4 can be intermittently transported to the inside of the kettle body 1, and the bottom of the feeding pipe 4 can be opened when feeding, and the bottom of the feeding pipe 4 can be blocked when stopping feeding. The feeding speed of the reactor can be controlled by controlling the rotation speed of the motor 72, thereby improving the feeding effect and safety of the reactor.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
