Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to an easily disassembled coupling device for a chemical reaction kettle stirrer. Background Art

[0002] A chemical reactor is a device used for chemical reactions, usually consisting of a container body, a stirring device, a heating or cooling system, and an inlet and outlet. The agitator is a device used to stir and mix reactants inside the reactor, usually consisting of a stirring motor, stirring blades, and a related stirring transmission system. The agitator is usually installed in the reactor cover, which makes the equipment inconvenient to operate during maintenance and cleaning.

[0003] A Chinese patent discloses a reactor (authorization announcement number CN202893349U), which includes a reactor body, a stirring device arranged in the reactor body, a feed port arranged at the top of the reactor body, and a discharge port arranged at the bottom of the reactor body. A motor is arranged above the reactor body, and the motor drives the stirring device to rotate. The stirring device extends into the reactor body, and stirring blades are arranged at its end and middle position. A plurality of stirring baffles and baffle connecting plates are evenly arranged on the inner wall of the reactor body. The stirring baffles are fixed on the inner wall of the reactor body through the baffle connecting plates, and the baffle connecting plates are 45 degrees to the inner wall of the reactor body. The stirring baffles and the baffle connecting plates are vertically connected, and the distance between the stirring baffles and the inner wall of the reactor body is 50 to 150 mm. The reactor of the utility model has a reasonable structural design, sufficient stirring, and can effectively improve product quality.

[0004] This patented technology has the advantage of very high product quality when in use, but there is still insufficient support during use. The agitator is integrally formed, which makes it difficult to disassemble the large structure when the interior needs to be cleaned or damaged for maintenance. It is very inconvenient to operate during cleaning and maintenance. Therefore, a technician in this field provides an easily detachable coupling device for a chemical reactor agitator to solve the problems raised in the above background technology.

[0042] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] Example 1

[0044] See also Figure 1-Figure 5 As shown, this embodiment is an easily detachable coupling device for a chemical reactor agitator, comprising a reactor cover 101,

[0045] The reaction kettle 100 comprises a kettle body 102 located at the lower end of a kettle cover 101;

[0046] The driving structure 200 includes a bearing 207 embedded in the kettle cover 101, a fixed shaft 208 rotatably inserted in the bearing 207, a docking seat 203 located at the upper end of the fixed shaft 208, a motor 201 located at the upper end of the kettle cover 101, and a docking shaft 202 fixed at the output end of the lower end of the motor 201;

[0047] The docking shaft 202 and the docking seat 203 are mutually engaged and installed, and the outer wall of the motor 201 is sleeved with a bracket 206;

[0048] A symmetrically distributed fixing plate 204 is provided at the upper end of the kettle cover 101, and the fixing plate 204 is rotatably plugged with a bracket 206 through a bolt 205, and a mounting bracket 103 is sleeved on the outer wall of the kettle body 102;

[0049] Using the drive structure 200;

[0050] The docking shaft 202 at the lower end of the motor 201 corresponds to the docking seat 203, and the docking shaft 202 is inserted into the docking seat 203. After the fixing plate 204 and the bracket 206 are docked, the bolt 205 is rotated and inserted into the fixing plate 204 and the inside of the docking plate to fix the bracket 206. When the motor 201 is running, the installation shaft is driven to rotate, thereby driving the stirring shaft 301 to rotate. When disassembling, the motor 201 and the fixed shaft 208 are convenient to disassemble, avoiding the problem that the motor 201 and the fixed shaft 208 are installed as one piece and cannot be disassembled and maintained separately. The motor 201 can be disassembled separately for easy maintenance.

[0051] Example 2

[0052] See also Figure 1-Figure 5 As shown, this embodiment is based on the embodiment 1 and also includes:

[0053] as well as;

[0054] The coupling structure 300 includes a docking plate 303 fixed at the lower end of the fixed shaft 208, a docking plate 304 located at the lower end of the docking plate 303, a stirring shaft 301 located at the lower end of the docking plate 304, a stirring rod 302 located on the outer wall of the stirring shaft 301, a positioning plate 313 distributed in a circular array at the upper end of the docking plate 304, a positioning groove 312 opened inside the docking plate 303, a travel plate 305 distributed in a circular array above the docking plate 304, a spring 309 located at one end of the travel plate 305, a support plate 310 fixed at the upper end of the docking plate 304 and connected to the spring 309, an extrusion sleeve 315 sleeved on the outer side of the fixed shaft 208, and an insert block 307 located at one end of the travel plate 305.

[0055] The outer wall of the fixed shaft 208 is provided with a thread groove 317, and a thread sleeve 314 is rotatably sleeved on the outer wall of the thread groove 317, and the lower end of the thread sleeve 314 is connected to the extrusion sleeve 315;

[0056] A limiting sleeve 316 is provided inside a lower end of the threaded sleeve 314 and is sleeved on the outer side of the fixed shaft 208 and rotatably mounted with the threaded groove 317;

[0057] The outer side of the travel plate 305 is provided with a conical surface 306 adapted to the inner wall of the extrusion sleeve 315;

[0058] A sliding sleeve 311 is embedded in the support plate 310, and a guide rod 308 having one end fixed on the travel plate 305 is slidably inserted in the sliding sleeve 311;

[0059] Performing use of the coupling structure 300;

[0060] When the stirring shaft 301 is in use, the docking plate 1 303 is docked with the docking plate 2 304, the positioning plate 313 is inserted into the positioning groove 312, and the insert block 307 is inserted into the positioning plate 313. The positioning plate 313 is fixed by the elastic support of the spring 309, and the rotational force of the fixed shaft 208 acts on the stirring shaft 301, driving the stirring rod 302 to stir the material inside the kettle body 102;

[0061] During use, the limiting sleeve 316 rotates on the outer wall of the thread groove 317. The limiting sleeve 316 is located on the inner side of the guide rod 308 to limit the guide rod 308, thereby preventing the guide rod 308 from moving over a long distance, causing the travel plate 305 to move over a long distance, and then causing the plug 307 to move out of the positioning plate 313, so that the stirring shaft 301 fixed by the elastic clamping connection is stable in use;

[0062] When the equipment needs maintenance, the traditional integrally installed stirring shaft 301 is connected to the kettle cover 101, which is relatively large as a whole, and the kettle cover 101 needs to be removed, which is very inconvenient for maintenance and cleaning. At this time, when the stirring shaft 301 needs to be disassembled for cleaning and maintenance, the gripping limit is to rotate the upper end of the movable sleeve, which is misaligned with the guide rod 308, and the gripping threaded sleeve 314 is rotated downward, driving the extrusion sleeve 315 to move downward, so that the extrusion sleeve 315 gradually applies an extrusion force to the stroke plate 305, and the stroke plate 305 squeezes the spring 309, and the spring 309 is forced to shrink, driving the plug block 307 to move inward. When the plug block 307 is separated from the positioning block, the docking plate 1 303 is separated from the docking plate 2 304, which is convenient for operation when cleaning and maintaining the splint shaft, avoiding the problem of very inconvenient operation inside the equipment. It is more convenient to clean and maintain through the coupling structure 300.

[0063] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
