Description

Technical Field

[0002] Acrylic polymer retanning agent, also known as acrylic resin retanning agent, is a very important type of synthetic tanning agent. It is the only material among retanning agents that will not reduce the strength of chrome soft leather but can improve its firmness and flexibility. The leather treated with it has good flexibility and light resistance.

[0003] The existing stirring device generally includes a tank body and a rotating shaft inserted inside the tank body, and a stirring member is arranged on the rotating shaft. The existing CN202022159535.7 is a silicone-modified acrylic polymer retanning agent stirring device. By providing a movable cover plate and a mounting plate, the driving motor of the stirring device and the rotating shaft can be separated, which is convenient for the staff to clean and maintain the stirring device, and also convenient for the staff to repair and replace damaged parts.

[0004] However, when replacing the stirring device of this comparative example, the rotating shaft and the stirring rod are fixedly connected and cannot be disassembled. When the stirring rod is used, a single stirring rod may break or deform. Therefore, when the stirring rod is broken or deformed, this comparative example needs to replace the rotating shaft and the stirring rod as a whole, and it is impossible to replace only the stirring rod separately, which results in a high replacement cost, making the practicality of this comparative example low.

The working principle of the condensation cavity, liquid inlet pipe, liquid discharge pipe, air inlet pipe and exhaust pipe in this scheme is the existing technology in the existing public patent: CN202221124421.1 low-temperature vacuum mixer, which will not be repeated here.

[0090] Furthermore, a valve is provided on the discharge pipe 3 .

[0091] Furthermore, in the initial state, the positioning slide block 14 slides into the positioning slide groove 13, and at this time the connecting block 17 slides into the fixing groove 21. At this time, the lower side of the connecting block 17 slides into the fixing groove 21 to fix the positioning slide block 14 and the mixing leaf 10. When the mixing leaf 10 needs to be damaged and the mixing leaf 10 needs to be disassembled, the sliding block 12 is pressed so that the sliding block 12 drives the pushing block 19 to move in the direction close to the connecting block 17. In this process, the second spring 18 is squeezed, and the inclined surface of the pushing block 19 pushes the top of the connecting block 17 during the movement. The wall causes the connecting block 17 to move upward, and the upward movement of the connecting block 17 drives the first spring 16 to be squeezed. When the connecting block 17 moves upward to its lower side and moves out of the fixing groove 21, the mixing leaf 10 can be pulled away from the fixing block 9 at this time, so that the positioning slider 14 and the mixing leaf 10 are separated from the fixing block 9, thereby completing the disassembly of the mixing leaf 10, and then the mixing leaf 10 can be replaced separately, thereby reducing the replacement cost, facilitating and quickly disassembling, and improving the replacement efficiency of the mixing leaf 10, thereby improving the synthesis efficiency of the acrylic acid retanning agent and increasing the practicability of the equipment.

[0092] Continuing from the above, the new positioning slider 14 and the mixing leaf 10 are then moved so that the new positioning slider 14 slides into the positioning slot 13, and the pressure on the sliding block 12 is released. Under the action of the release force of the second spring 18, the sliding block 12 is driven to reset, and under the action of the release force of the first spring 16, the connecting block 17 is pushed to slide into the fixing slot 21, and then the positioning slider 14 and the mixing leaf 10 are re-fixed, thereby completing the replacement of the mixing leaf 10, and then the mixing leaf 10 can be replaced separately, thereby reducing the replacement cost, facilitating and quickly replacing, and improving the replacement efficiency of the mixing leaf 10, thereby improving the synthesis efficiency of the acrylic acid retanning agent, thereby facilitating the disassembly and installation of the mixing leaf 10, and thereby increasing the practicality of the equipment.

[0093] When in use, start the electric push rod 5 to drive the sealing cover 4 and the disassembly mechanism to move up and down. When the equipment needs to be removed and the mixing leaves 10 needs to be replaced, it is necessary to start the electric push rod 5 to drive the sealing cover 4 to move upward, and then move the disassembly mechanism upward and out of the synthesis tank 2, so as to facilitate the replacement of the mixing leaves 10, thereby increasing the practicality of the equipment.

[0094] Furthermore, when in use, the electric push rod 5 is started to drive the sealing cover 4 to close with the synthesis tank 2, thereby sealing the sealing cover 4, and then the motor 7 is started. The motor 7 starts to drive the fixed shaft 8 to rotate, and then synchronously drives the mixing blades 10 to rotate. The mixing blades 10 mix and synthesize the raw materials in the synthesis tank 2.

[0095] Furthermore, in the present embodiment, the first spring 16 and the second spring 18 have sufficient elastic force in the initial state, so that the first spring 16 and the second spring 18 will not be elastically deformed due to factors such as water flow, inertia, liquid strength, etc. during the stirring process, thereby ensuring that the positioning slider 14 will not be separated from the fixed block 9 during the operation of the equipment, thereby ensuring the safety of the equipment.

[0096] Working principle: When the device is in use, in the initial state, the positioning slider 14 slides into the positioning slot 13, and at this time the connecting block 17 slides into the fixing slot 21, and at this time the lower side of the connecting block 17 slides into the fixing slot 21 to fix the positioning slider 14 and the mixing leaf 10. When the mixing leaf 10 needs to be damaged and needs to be disassembled, the sliding block 12 is pressed so that the sliding block 12 drives the pushing block 19 to move toward the connecting block 17. In this process, the second spring 18 is squeezed, and during the movement of the pushing block 19, its inclined surface pushes the top wall of the connecting block 17, so that the connecting block 17 moves upward, and the upward movement of the connecting block 17 drives the squeezing of the first spring 16. When the connecting block 17 moves upward until its lower side moves out of the fixing slot 21, the mixing leaf 10 can be pulled in the direction away from the fixing block 9. , so that the positioning slider 14 and the mixing leaf 10 are separated from the fixing block 9, thereby completing the disassembly of the mixing leaf 10, and then a new positioning slider 14 and the mixing leaf 10 are released, so that the new positioning slider 14 slides into the positioning slide groove 13, and the pressure on the sliding block 12 is released. Under the action of the release elastic force of the second spring 18, the sliding block 12 is driven to reset, and under the action of the release elastic force of the first spring 16, the connecting block 17 is pushed to slide into the fixing groove 21, and then the positioning slider 14 and the mixing leaf 10 are fixed again, thereby completing the replacement of the mixing leaf 10, and then the mixing leaf 10 can be replaced separately, reducing the replacement cost, facilitating the replacement, and quickly replacing, improving the replacement efficiency of the mixing leaf 10, and thereby improving the synthesis efficiency of the acrylic acid retanning agent, thereby facilitating the disassembly and installation of the mixing leaf 10, and thereby increasing the practicality of the equipment.
