Description

Technical Field

[0001] The utility model relates to the technical field of liquid mixing, in particular to an anti-condensation sealant raw material mixing device. Background Art

[0002] Sealant is also called sealant; sealing material. It is a material based on high-density material. It is deformed with the shape of the sealing surface, not easy to flow, and has a certain degree of adhesion. It can prevent external impurities from invading and internal substances from leaking in the static joints of various machines. It has good sealing performance. It is divided into two categories: bonding type and non-bonding type.

[0003] In the prior art, the Chinese utility model with authorization announcement number: CN212663388U discloses a mixing device for stirring composite additives, which relates to the technical field of composite additives. In order to solve the problem that there are many kinds of oilfield additives in the prior art, multiple additives can be mixed and used at the same time when in use, but these additives cannot be added synchronously, resulting in the problem that the reaction is not comprehensive enough. The additive mixing tank group includes a liquid stirring tank and a solid mixing tank, the top of the solid mixing tank is provided with an additive raw material tank, and there are four additive raw material tanks, the top of the additive raw material tank is provided with a sealing valve port, and the sealing valve port is fixedly connected to the additive raw material tank, one side of the additive raw material tank is provided with a mixing motor, and the mixing motor is connected to the additive raw material tank through a bracket, the outer surface of the top of the liquid stirring tank is provided with a liquid delivery pipe port, and one side of the bottom of the liquid stirring tank is provided with an output valve pipe, and the bottom of the liquid stirring tank is provided with a stirring motor.

[0004] In the above technical solution, the vortex turntable is driven to rotate by a stirring motor to stir the liquid raw materials inside the liquid stirring tank and make them rotate in the same direction. Since the liquid raw materials all rotate in the same direction, the mixing efficiency is relatively reduced, resulting in a deviation in the mixing effect. At the same time, the equipment cannot be used for sealant raw materials. After the sealant reacts and expands in the air after mixing different raw materials, when the device is stirring and mixing, the raw materials are directly in contact with the air inside the equipment, which causes the raw materials to directly react and expand during mixing, resulting in the sealant failing after discharge and being unusable.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figures 1 to 5 The present invention discloses a raw material mixing device for anti-condensation sealant, comprising:

[0027] A mixing tank 1 for mixing sealant raw materials;

[0028] A partition 2 is fixed inside the mixing tank 1, and the partition 2 divides the internal space of the mixing tank 1 into a mixing chamber 3 and an equipment chamber 4. Two sets of stirring shafts 5 are rotatably connected to the partition 2 through bearings. One end of the stirring shaft 5 extends into the mixing chamber 3 and is rotatably connected to the inner wall of the mixing tank 1 through a bearing. The other end of the stirring shaft 5 passes through the partition 2 and extends into the equipment chamber 4 and is provided with a driving component 6. A stirring component 7 is installed on the stirring shaft 5.

[0029] It also includes a fixed seat 8 arranged at the bottom of the mixing tank 1, the inner cavity of the fixed seat 8 is slidably provided with a moving frame 9, the mixing tank 1 is fixed to the inner cavity of the moving frame 9, and the fixed seat 8 is provided with a translation component 10 for reciprocating the moving seat;

[0030] The top of the mixing tank 1 is connected to a feed pipe 11 and an exhaust pipe 12, and the bottom of the mixing tank 1 is connected to a discharge pipe 13;

[0031] By arranging two groups of stirring shafts 5 in the mixing chamber 3, the two groups of stirring shafts 5 are driven in opposite directions by the driving assembly 6, and the sealant raw materials are fully stirred and mixed by the stirring assembly 7. At the same time, before the raw materials are injected, the air in the mixing tank 1 is extracted from the exhaust pipe 12 by the vacuum pump, so that the mixing chamber 3 is in a vacuum state, and the mixing chamber 3 is in a negative pressure. When the feed pipe 11 is connected with the raw materials, the raw materials can be sucked into the mixing chamber 3 more quickly, and at the same time, the raw materials are prevented from contacting and reacting with the air during mixing, which causes the mixed sealant to become directly ineffective and unusable. This can not only improve the mixing quality, but also ensure the mixing efficiency.

[0032] The driving assembly 6 includes a driving motor 61 located in the equipment cavity 4. The driving motor 61 is fixed on the inner wall of the mixing tank 1. The output shaft of the driving motor 61 is fixedly connected to the end of a group of stirring shafts 5. The stirring shafts 5 extend to the outside of one end of the equipment cavity 4 and are fixed with a driving gear 62. Two groups of mutually meshing linkage gears 63 are rotatably connected to the partition 2 through a movable shaft. The linkage gear 63 is located between the driving gears 62 and meshes with the driving gears 62. A group of stirring shafts 5 are driven to rotate by the driving motor 61, and then the driving gear 62 is meshed with the linkage gear 63 to make the two groups of stirring shafts 5 rotate synchronously in opposite directions. The stirring assembly 7 is used to fully mix the raw materials to ensure the mixing quality.

[0033] The translation assembly 10 includes a telescopic cylinder 101 fixed to one side of the fixed seat 8, the piston rod of the telescopic cylinder 101 penetrates the inner cavity of the fixed seat 8 and is fixed with a push block 102, and a support spring 103 is fixed on the side of the inner cavity of the fixed seat 8 away from the telescopic cylinder 101, and the other side of the support spring 103 is in contact with the moving frame 9, and the push block 102 is driven by the telescopic cylinder 101 to move, and then the push block 102 pushes the moving frame 9 to translate in the fixed seat 8 and squeezes the support spring 103, and the support spring 103 undergoes elastic deformation. When the push block 102 retracts under the drive of the telescopic cylinder 101, the support spring 103 pushes the moving frame 9 to translate in the opposite direction, and then the mixing tank 1 is made to reciprocate, so that the raw materials in the mixing chamber 3 move and collide, which can improve the mixing effect.

[0034] The stirring assembly 7 includes two groups of extension rods 71 ​​fixed on the stirring shaft 5, and curved plates 72 are fixed between the extension rods 71. By setting the structure of the stirring assembly 7, it is ensured that the raw materials can rotate under the rotation of the curved plates 72 and be transported along the axial direction of the stirring shaft 5 to avoid repeated stirring and mixing of the raw materials at the same position.

[0035] The feed pipe 11, the air extraction pipe 12 and the discharge pipe 13 are all connected to the mixing chamber 3. Control valves are installed in the feed pipe 11, the air extraction pipe 12 and the discharge pipe 13. The air tightness of the mixing chamber 3 can be ensured by setting the control valves to prevent air from entering.

[0036] Limiting rods 14 are fixed on both sides of the moving frame 9. The end of the limiting rod 14 away from the moving frame 9 passes through the fixed seat 8 and extends outward. Through the setting of the limiting rod 14, it is ensured that the moving frame 9 moves smoothly inside the fixed seat 8 to prevent the moving frame 9 from shaking inside the fixed seat 8, which will reduce the stability of the mixing tank 1.

[0037] During specific use, the air in the mixing chamber 3 is extracted by connecting the vacuum pump to the exhaust pipe 12, the exhaust pipe 12 is closed, and then the raw materials are poured into the feeding pipe 11, and the driving motor 61 is started. The driving motor 61 drives one group of stirring shafts 5 to rotate, and then the stirring shafts 5 drive another group of stirring shafts 5 to rotate through the driving gear 62 and the linkage gear 63, so that the two groups of stirring shafts 5 rotate synchronously in opposite directions, and the stirring assembly 7 is used to mix the raw materials. At the same time, the telescopic cylinder 101 drives the push block 102 to move, and the push block 102 translates the moving frame 9, and then the moving frame 9 squeezes the supporting spring 103. When the piston rod of the telescopic cylinder 101 retracts, the supporting spring 103 pushes the moving frame 9 and the mixing tank 1 in the opposite direction to make the mixing tank 1 reciprocate, thereby ensuring that the raw materials are fully mixed and the mixed sealant is discharged from the discharge pipe 13.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
