Description

Technical Field

[0001] The utility model relates to the technical field of reaction equipment, and particularly relates to a reaction kettle with a liftable kettle cover. Background Art

[0002] A reaction kettle is a device used for carrying out chemical reactions, and is widely used in industries such as chemical engineering, pharmaceuticals, and food. It usually consists of a sealed container, a stirring device, a heating or cooling device, and connecting pipes, etc. The reaction kettle can carry out various chemical reactions under a controlled environment, such as synthesis, decomposition, acid-base neutralization, etc. A stirring device is usually equipped inside the reaction kettle to mix the reactants and promote the progress of the reaction. The reaction kettle is usually equipped with a heating or cooling device to control the reaction temperature and ensure the stability of the reaction conditions. After the reaction is completed, the product can be separated from the reaction kettle through the connected pipes for subsequent extraction or purification processes. The reaction kettle has good sealing performance, which can prevent the leakage of harmful substances during the reaction process and protect the safety of operators.

[0003] However, the existing reaction kettles often encounter the following problems during use:

[0004] (1) The kettle covers of the existing reaction kettles are all opened and closed manually. Manually opening and closing the kettle cover has potential safety hazards. Especially in the case of high temperature, high pressure or toxic substances, operators may face risks such as scalding and explosion.

[0005] (2) Since the reaction kettle needs to ensure a sealed environment, the kettle cover is generally heavy. In some cases where it is necessary to frequently open and close the kettle cover to observe the internal chemical reaction, it is extremely inconvenient and time-consuming to open and close the kettle cover frequently. Summary of the Utility Model

SPECIFIC EMBODIMENTS

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0040] In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and defined, the terms "arranged", "set", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0041] As Figures 1-4 shown, a reactor with a liftable kettle lid includes: a base 1, a support plate 2, a lifting housing 3, an outer housing 4, a transmission rod 5, a motor 6, a transmission thread 7, a transmission gear 8, a screw rod 9, and a sliding member 10. There are two support plates 2, and the two support plates 2 are longitudinally arranged above the base 1. There are two lifting housings 3, and the two lifting housings 3 are respectively located on one side of the two support plates 2. The outer housing 4 is fixedly installed at the bottom of the lifting housing 3. The two lifting housings 3 are respectively fixedly connected to one side of the two support plates 2. One side of the outer housing 4 is fixedly connected to the support plate 2. The arrangement of the outer housing 4 and the support member provides support for the lifting housing 3. One end of the transmission rod 5 is located inside the outer housing 4, and one end of the transmission rod 5 horizontally penetrates through the two support plates 2. One end of the transmission rod 5 is installed at the output end of the motor 6. The transmission threads 7 are arranged at both ends of the transmission rod 5. The transmission gear 8 is located inside the outer housing 4, and the transmission gear 8 meshes with the transmission thread 7. Once the screw rod 9 rotates, it will drive the transmission gear 8 to rotate. Also, because the screw rod 9 is arranged inside the housing, the bottom end of the screw rod 9 is fixedly connected to the center of the tooth surface of the transmission gear 8. The sliding member 10 is sleeved on the rod body of the screw rod 9. Then, when the transmission gear 8 rotates and the screw rod 9 rotates, the sliding member 10 on the rod body of the screw rod 9 will move up and down.

[0042] In this embodiment, as Figures 2-3 shown, a slideway 11 is opened on one side of the lifting housing 3. One end of a connecting member 12 is fixedly connected to the sliding member 10, and the other end of the connecting member 12 passes through the slideway 11 and is fixedly connected to the edge of the kettle lid 13. The kettle lid 13 is located between the two lifting housings 3. When the sliding member 10 moves up and down, the sliding member 10 will drive the kettle lid 13 to move up and down through the connecting rod. The kettle body 14 is located below the kettle lid 13. A fixing ring 15 is sleeved on the bottom of the kettle body 14, and the ring body of the fixing ring 15 is fixedly connected to the lifting housing 3. Since the bottom of the reactor is a circular arc with a gradually shrinking outer diameter, the outer shape of the fixing ring 15 is set as an inclined ring with a gradually shrinking diameter. Such corresponding setting can prevent the kettle body 14 from falling. A limiting ring 16 is sleeved on the kettle body 14, and the ring body of the limiting ring 16 is fixedly connected to the lifting housing 3. The arrangement of the limiting ring 16 can effectively prevent the kettle body 14 from shaking and ensure the stability of the overall facility.

[0043] In the above embodiments, the numbers of the outer housing 4 and the screw 9 are both corresponding to the lifting housing 3. In this way, two sliding members 10 are connected to the kettle cover 13 through the connecting member 12. The two sets of lifting mechanisms can provide stability and support effects for the settings of the kettle cover 13 and the kettle body 14. The threads on the transmission rod 5 have the same helix direction. The same helix direction can ensure that the two screws 9 after power transmission rotate in the same direction, avoiding the opposite movement directions of the two sliding members 10 sleeved thereon caused by the opposite helix directions of the screws 9, so that the device cannot be used normally.

[0044] It should be noted that for a reactor with a liftable kettle cover designed by the present invention, during use, the motor 6 is started. The rotation of the motor 6 drives the transmission rod 5 at the output end. The rotation of the transmission rod 5 drives the transmission threads 7 at both ends to rotate. The rotation of the transmission threads 7 drives the transmission gear 8. The rotation of the transmission gear 8 drives the screw 9 on its tooth surface. The rotation of the screw 9 drives the sliding member 10 to move axially along the screw 9. The axial movement of the sliding member 10 drives the connecting member 12 to move. The movement of the connecting member 12 drives the kettle cover 13 to rise or fall. Thus, the usage process ends.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it is understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
