Description

Technical Field

[0001] The utility model relates to a reaction kettle, in particular to a reaction kettle for producing sealant, and belongs to the technical field of sealant production. Background Art

[0002] In the prior art, for example, a utility model with application number 201921696338.X discloses a reactor for sealant production. In order to solve the problem that the traditional sealant reactor discharges mostly by its own gravity, and the sealant itself is viscous, and the discharge is difficult and incomplete, a cylinder, a turntable and a sponge are provided. The bottom end of the turntable is truncated cone-shaped, and the bottom end of the tank body is a truncated cone-shaped groove, which is convenient for squeezing the mixture out through the cylinder. By providing a cylinder, a motor and a sponge, the reactor is not allowed to be cleaned with hard materials or objects with rough surfaces. The motor drives the sponge to rotate to clean the reactor, and the cylinder drives the sponge to move up and down for cleaning.

[0003] Similar to the above application, there are still some shortcomings:

[0004] When the turntable moves downward, the sponge contacts the inside of the kettle body, and the kettle body cannot be sealed and separated from the top and bottom, which affects the extrusion and discharge effect of the raw materials. The sponge has a certain adsorption capacity, and part of the raw materials will be absorbed by the sponge. In addition, when the turntable rotates, the sponge will cause friction with the inner wall of the kettle body, generating powder residue, which affects the production of sealant.

[0005] For this reason, a sealant production reactor is designed to optimize the above-mentioned problems. Utility Model Content

[0006] The main purpose of the utility model is to provide a reaction kettle for sealant production, which is provided with an annular airbag on the outer side of an extrusion plate, and cooperates with an air cavity, air holes, a piston, a pull rod, a limit plate and a reset spring inside the extrusion plate to form an exhaust mechanism. In the process of the extrusion plate moving downward, the elastic force of the reset spring can be used to control the upward reset of the piston, so that the gas inside the air cavity is rushed into the annular airbag. At this time, the annular airbag fits tightly with the inner wall of the kettle body, ensuring that the extrusion plate can separate the upper and lower parts of the kettle body during the discharge process, thereby improving the discharge rate of the raw materials. At the same time, the annular airbag can scrape the raw materials on the inner wall of the kettle body clean, which is more practical. In addition, the use of the exhaust mechanism can extract the gas inside the annular airbag into the air cavity during the process of the extrusion plate rising and resetting, thereby avoiding the wear of the annular airbag during the stirring process and improving the service life.

DETAILED DESCRIPTION

[0022] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0023] like Figure 1-Figure 4As shown, this embodiment provides a reaction kettle for sealant production, including a kettle body 1, an extrusion plate 7 slidably arranged inside the kettle body 1, and a cylinder 6 for controlling the vertical lifting of the extrusion plate 7, an annular slide groove 10 is provided on the top of the extrusion plate 7, and sliders 11 are evenly installed inside the annular slide groove 10, and the slider 11 is fixed to the output end of the cylinder 6, a stirring motor 2 is installed at the middle position of the top of the kettle body 1, and the output end of the stirring motor 2 is located inside the kettle body 1, and a fixed plate 3 is horizontally installed at the output end of the stirring motor 2, and a stirring rod 4 is evenly and vertically fixed at the bottom end of the fixed plate 3, a fixing ring 5 is fixed on the inner top of the kettle body 1, and the cylinder 6 is vertically installed on the fixing ring 5, a sliding hole 8 cooperating with the stirring rod 4 is provided on the extrusion plate 7, an annular air bag 9 is provided on the outer side of the extrusion plate 7, and an inflation and exhaust mechanism for supplying air to the inside of the annular air bag 9 is provided inside the extrusion plate 7.

[0024] The general working principle is as follows: during the stirring process of the sealant, the cylinder 6 is reset, the extrusion disk 7 is at the inner top of the kettle body 1, and at the same time, the gas inside the annular airbag 9 is discharged by the filling and exhaust mechanism, and it is tightly attached to the inner wall of the extrusion disk 7 without contacting the inner wall of the kettle body 1. Therefore, during the rotation of the extrusion disk 7, the annular airbag 9 will not have relative friction with the inner wall of the kettle body 1, and the stirring motor 2 starts to control the rotation of the stirring rod 4 at the bottom of the fixed disk 3. The stirring rod 4 stirs the sealant and drives the extrusion disk 7 to rotate together. After the processing is completed, the stirring motor 2 is turned off, and the cylinder 6 is started to control the downward movement of the extrusion disk 7. At this time, the inside of the annular airbag 9 is filled with gas by the filling and exhaust mechanism, and it is tightly fitted with the inner wall of the kettle body 1, ensuring the cleaning effect of the inner wall of the kettle body 1 during the downward movement of the extrusion disk 7. At the same time, the extrusion disk 7 seals and isolates the upper and lower parts of the kettle body 1, and the raw materials can be directly squeezed out during the downward movement of the extrusion disk 7.

[0025] In this embodiment, a rubber sleeve is fixed to the inner wall of the sliding hole 8 , and the inner side of the rubber sleeve is tightly fitted to the outer wall of the stirring rod 4 .

[0026] Partial working principle: the sealing effect inside the slide hole 8 is ensured to prevent the sealant from squeezing out of the slide hole 8 when it is squeezed out.

[0027] In this embodiment, the bottom of the extrusion plate 7 is arc-shaped, and the shape of the bottom of the extrusion plate 7 matches the inner bottom of the kettle body 1 .

[0028] Partial working principle: During the process of the extrusion disc 7 moving downward to discharge the material, the bottom can fit tightly with the inner bottom of the kettle body 1 to ensure that the raw material is completely discharged.

[0029] In this embodiment, four groups of cylinders 6 are provided, and the angle between adjacent cylinders 6 is 90°.

[0030] Partial working principle: Through the use of multiple groups of cylinders 6, the stable downward movement of the extrusion disk 7 can be guaranteed, and the stability of the extrusion disk 7 during rotation can also be guaranteed.

[0031] In this embodiment, the inflation and exhaust mechanism includes an air cavity 12, an air hole 13, a piston 14, a pull rod 15, a limit plate 16 and a return spring 17. The air cavity 12 is vertically opened on the outside of the extrusion disk 7. An air hole 13 is provided between the top of the air cavity 12 and the annular airbag 9. A piston 14 is slidably arranged inside the air cavity 12. A pull rod 15 is fixed to the top of the piston 14. The pull rod 15 extends to the outside of the extrusion disk 7 and is slidably connected to the extrusion disk 7. A limit plate 16 is fixed between the tops of the pull rods 15. A return spring 17 is evenly provided between the bottom of the limit plate 16 and the inner top of the extrusion disk 7.

[0032] Local working principle: When the sealant is stirred, the extrusion disk 7 is located at the inner top of the kettle body 1, and the limit disk 16 is tightly attached to the bottom of the fixing ring 5, and the return spring 17 is squeezed at the same time. The piston 14 moves to the inside of the air cavity 12, and the air inside the annular airbag 9 is sucked into the inside of the air cavity 12. At this time, the annular airbag 9 is in a deflated state. During discharge, the limit disk 16 loses the extrusion force, and the return spring 17 is reset, automatically controlling the piston 14 to move upward, and the gas inside the air cavity 12 is injected into the inside of the annular airbag 9. The annular airbag 9 expands and fits tightly against the inner wall of the kettle body 1.

[0033] In this embodiment, the number of the return springs 17 is the same as the number of the pull rods 15 , and the pull rods 15 pass through the inside of the return springs 17 .

[0034] Partial working principle: The expansion effect of the annular airbag 9 is ensured by using multiple sets of return springs 17. In addition, the pull rod 15 is limited to prevent the return spring 17 from deforming outward during the extrusion process.

[0035] In this embodiment, balls 18 are evenly mounted on the top of the limiting plate 16 in an annular array for uniform rotation, and the balls 18 are located below the fixing ring 5 .

[0036] Partial working principle: When the extrusion plate 7 rotates, it will drive the limit plate 16 to rotate, and the ball 18 on the top of the limit plate 16 will contact with the fixing ring 5, thereby reducing the friction resistance.

[0037] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
