Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a solvent-resistant reaction kettle. Background Art

[0002] During the process of preparing glue for the production of copper clad laminates, a reaction kettle is required. Currently, the lid of the reaction kettle is generally provided with a sealing strip. Conventionally, a groove is used to install and fix the sealing strip. The sealing strip is mainly made of ethylene propylene diene monomer (EPDM) or fluororesin and is adhered by glue to ensure the sealing stability between the reaction kettle lid and the kettle body.

[0003] However, during the use process, a swelling phenomenon will occur, resulting in the dropping of the sealing strip, causing poor sealing effect of the reaction kettle; moreover, the method of adhesion is not only difficult to operate, but more troublesome is that when the kettle lid needs to be opened after use, it is easy to damage the sealing strip and the sealing strip needs to be frequently replaced.

[0023] Embodiment:

[0024] Referring to Figures 1-4 , a solvent-resistant reactor includes a kettle body 1 and a kettle cover 2. The shapes and sizes of the kettle body 1 and the kettle cover 2 are not limited herein and can be adjusted according to actual situations. Only a part of the structure of the kettle body 1 is shown in the accompanying drawings. It further includes: a fastening unit provided on the outer side wall of the kettle body 1, which can rotate upward along the side wall of the kettle body 1 to the upper part of the kettle cover 2 for fastening the kettle cover 2 and the kettle body 1; a sealing part provided on the side of the kettle cover 2 close to the kettle body 1 for sealing the kettle body 1.

[0025] Specifically, referring to Figure 1 and Figure 4, the fastening unit includes: a fastener 9 rotatably connected to the outer side wall of the kettle body 1. The fastener 9 and the kettle body 1 are connected by a hinged connection. On the side of the fastener 9 close to the kettle lid 2, there is an inclined surface 10. This is to ensure that when the fastener 9 rotates, it can stably rotate to the top of the kettle lid 2 and at the same time squeeze the kettle lid 2 towards the kettle body 1. A first installation groove 12 is provided on the fastener 9. Among them, the fastener 9 is in a C-shaped opening, and the opening of the fastener 9 is close to the kettle lid 2. A link mechanism provided on the kettle body 1, its driving end is rotatably connected to the fastener 9 and is used to drive the fastener 9 to rotate. When the fastener 9 rotates above the kettle lid 2, the side of the fastener 9 close to the inclined surface 10 is in close contact with the kettle lid 2 until the inclined surface 10 is completely above the kettle lid 2.

[0026] Refer to Figure 4 , the link mechanism includes a connecting rod 11 rotatably connected to the outer side wall of the kettle body 1. A second installation groove 13 is provided at the end of the connecting rod 11 far from the kettle body 1. Among them, a connecting rod 14 is provided in the first installation groove 12 and the second installation groove 13. One end of the connecting rod 14 is rotatably connected in the first installation groove 12, the middle position of the connecting rod 14 is rotatably connected in the second installation groove 13, and a driving part is provided at the free end of the connecting rod 14. Among them, the connecting rod 11 and the kettle body 1 are connected by a hinged connection, and the connecting rod 14 and the first installation groove 12 and the second installation groove 13 are connected by a pin shaft.

[0027] Refer to Figure 3 and Figure 4 , the driving part includes a cylinder 15 rotatably connected to the outer side wall of the kettle body 1. The cylinder 15 and the kettle body 1 are connected by a hinged connection. A third installation groove 16 is provided at the end of the connecting rod 14 far from the fastener 9. The end of the cylinder 15 far from the kettle body 1 is rotatably connected in the third installation groove 16, and the end of the cylinder 15 far from the kettle body 1 and the third installation groove 16 are connected by a pin shaft. The specific structure of the cylinder 15 can refer to the technical solutions in the prior art. Those skilled in the art can know and will not be elaborated here. A hydraulic rod or the like can also be used. The length of the cylinder 15 can be adjusted according to needs.

[0028] Refer to Figures 1-3, the sealing part includes a groove 6 opened on the side of the kettle lid 2 close to the kettle body 1. A sealing ring 7 is provided on the inner side of the groove 6 of the kettle lid 2, and the sealing ring 7 is connected to the kettle lid 2 in a nested manner. When the kettle lid 2 rotates above the kettle body 1, through the extrusion between the kettle body 1 and the sealing ring 7, a good fixing effect can be achieved on the sealing ring 7, thereby preventing the sealing ring 7 from falling off from the kettle lid 2 during use. It should be noted that when installing the sealing ring 7, it can be installed in a nested manner through its own elasticity. After installation, the embedded part of the sealing ring 7 can play a good positioning effect. On the side of the groove 6 far from the sealing ring 7 (which can be understood as the outer side), a plurality of extrusion blocks 8 are fixedly connected. The extrusion blocks 8 and the kettle lid 2 can be integrally formed or fixed by welding to ensure the firmness of the extrusion blocks 8 during use. Among them, the distance between the sealing ring 7 and the extrusion blocks 8 matches the radial dimension between the inner and outer side walls at the top of the kettle body 1. When the kettle lid 2 rotates onto the kettle body 1, the sealing ring 7 closely fits with the inner side wall of the kettle body 1, thereby achieving a sealing effect on the kettle body 1. And the side of the extrusion block 8 close to the sealing ring 7 is inclined, which can further increase the extrusion effect.

[0029] Refer to Figures 1-2 , it also includes a connecting piece 3 fixedly connected to the outer side wall of the kettle body 1. The connecting piece 3 can be fixed by welding to ensure the stability of the connecting piece 3 during use. A connecting seat 4 is fixedly connected to the side of the kettle lid 2 close to the connecting piece 3. The connecting piece 3 and the connecting seat 4 are rotatably connected, and the connecting piece 3 and the connecting seat 4 adopt a pin connection method. A handle 5 is fixedly connected to the side of the kettle lid 2 far from the kettle body 1. By rotating the handle 5, the kettle lid 2 can be rotated along the connecting seat 4 to facilitate the opening and closing of the kettle lid 2.

[0030] In the present utility model, initially, the fastener 9 is located outside the kettle lid 2 and does not affect the rotation between the kettle lid 2 and the kettle body 1. The kettle lid 2 can be normally opened and closed to facilitate adding reactants into the kettle body 1.

[0031] When working, hold the handle 5 and rotate the kettle lid 2 towards the top of the kettle body 1. When the kettle lid 2 rotates above the kettle body 1, drive the cylinder 15 to contract inward. Under the action of the connecting rod 14 and the connecting rod 11, drive the fastener 9 to rotate towards the top of the kettle lid 2, and under the action of the inclined surface 10, the fastener 9 can easily rotate above the kettle lid 2 and press the kettle lid 2 and the kettle body 1 tightly. When the connection point of the fastener 9 and the connecting rod 14 is on the same straight line as the two ends of the connecting rod 11, at this time, the mechanism is in a specific position, and the force exerted by the connecting rod 14 on the fastener 9 through the connecting rod 11 is zero, resulting in the fastener 9 being unable to move, so as to prevent the kettle lid 2 and the kettle body 1 from shifting during the reaction, thereby achieving a better sealing effect.

[0032] In addition, when the kettle cover 2 is rotated onto the kettle body 1, under the action of the extrusion block 8, the kettle body 1 can be closely attached to the sealing ring 7, further improving the sealing effect of the reaction kettle.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
