Description

Technical Field

[0001] This utility model relates to the technical field of sponge raw material mixing equipment, specifically a sponge raw material mixing device. Background Technology

[0002] Sponges are porous materials with excellent water absorption, making them suitable for cleaning items. During the production of sponges, raw materials (such as polyether polyols, isocyanates, catalysts, foaming agents, etc.) are initially mixed evenly. The temperature and mixing time vary depending on the type of sponge, but the initial mixing time is generally 3 to 5 minutes.

[0003] Currently, reaction vessel-type sponge raw material mixing devices generally have a jacket on the outside of the vessel to ensure the mixing temperature. However, when the material is first fed, the material in the center of the vessel is generally colder than the material on the periphery, resulting in uneven mixing. At the same time, the single-layer blades used inside the traditional vessel also need to be improved in terms of stirring and mixing effect. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a sponge raw material mixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sponge raw material mixing device, comprising a vessel body, a vessel lid, a motor, a stirring shaft, a double-layer paddle agitator, and an extension tube. The vessel lid is provided on the upper surface of the vessel body. A motor is mounted on the center of the upper surface of the vessel lid via a motor mount. The output shaft of the motor is connected to the top of the stirring shaft via a coupling. The bottom of the stirring shaft is connected to the double-layer paddle agitator, which includes a connecting sleeve, an upper paddle, and a lower paddle. The connecting sleeve is inserted into the bottom of the stirring shaft and fastened with bolts. The outer surface is uniformly provided with upper and lower blades, with a gap between them. The outer surface of the vessel is wrapped with a jacket. The lower end of the inner wall of the vessel is provided with two layers of fixed sleeves in a circumferential direction. Each of the two layers of fixed sleeves has an extension tube inserted inside. The extension tube and the end away from their respective fixed sleeves are provided with a cap. The inside of the extension tube is connected to the inside of the jacket through the fixed sleeve. One layer of extension tube is located between the upper and lower blades, and the other layer of extension tube is located above the upper blade. The two layers of extension tubes are staggered.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

One layer of extension tube is located between the upper and lower blades, and the other layer of extension tube is located above the upper blade.

The upper surface of the vessel cover 2 is also provided with several feed ports 13, a thermometer port 14, and a pressure gauge port 15. The feed ports 13 are used to feed different raw materials. The thermometer port 14 and the pressure gauge port 15 are used to install thermometers and pressure gauges, respectively, so as to realize the monitoring of the internal temperature and pressure of the vessel body 1. The output shaft of the motor 3 is connected to the top of the stirring shaft 4 through a coupling. The bottom of the stirring shaft 4 is connected to the double-layer paddle agitator. The double-layer paddle agitator includes a connecting sleeve 7, an upper paddle 8, and a lower paddle 9. The connecting sleeve 7 is inserted into the bottom of the stirring shaft 4 and fastened by bolts. The upper paddle 8 and the lower paddle 9 are evenly arranged on the outer surface of the connecting sleeve 7. There is a gap between the upper blade 8 and the lower blade 9. The outer surface of the vessel body 1 is covered with a jacket 10. The lower part of the jacket 10 is provided with a heat exchange medium inlet 17, and the upper side of the jacket 10 is provided with a heat exchange medium outlet 18. The heat exchange medium enters and leaves the jacket 10 through the heat exchange medium inlet 17 and the heat exchange medium outlet 18, respectively. A support seat 19 is also provided around the jacket 10 to support and fix the vessel body. Two layers of fixed sleeves 11 are provided around the lower end of the inner wall of the vessel body 1 in a circumferential direction. An extension tube 5 is inserted into the inner side of each of the two layers of fixed sleeves 11. A cap 12 is provided at the end of the extension tube 5 away from its respective fixed sleeve 11. The inside of the extension tube 5 is connected to the inside of the jacket 10 through the fixed sleeve 11.

The two layers of extension tube 5 are staggered. A discharge port 16 is provided at the bottom of the vessel body 1 to realize the discharge.

[0018] Installation method and operating principle: First, two layers of through holes are opened at the bottom of the vessel body 1. Multiple fixing sleeves 11 are welded inside the vessel body 1 at the through holes. Next, the extension tube 5 of one end cap 12 is inserted into the fixing sleeve 11 and sealed with it by welding. Then, the jacket 10 is fitted onto the outside of the vessel body 1 and welded to it. The connecting sleeve 7 with the upper impeller 8 and lower impeller 9 is inserted into the bottom of the stirring shaft 4. The motor 3 is installed on the motor base 6 on the upper surface of the vessel cover 2. The top of the stirring shaft 4 is connected to the output shaft of the motor 3 via a coupling. Finally, the vessel cover 2 is lifted, and the double-layer impeller agitator and stirring shaft 4 are inserted into the vessel body 1, ensuring that the upper impeller 8 and lower impeller 9 avoid the extension tube 5. Installation is complete. The feed inlet 13 is connected to each raw material storage tank via a pump and pipeline. A thermometer is installed on the thermometer port 14, and a pressure gauge is installed on the pressure gauge port 15.

The internal temperature of the vessel body 1 is controlled at 20-40℃ according to different sponges. The heat exchange medium enters each extension tube 5 at the same time. Then the motor 3 is started, and the motor 3 drives the stirring shaft 4 to rotate, thereby driving the double-layer paddle agitator to rotate, thereby realizing the mixing and stirring of the raw materials. After the mixing and stirring is completed, it is discharged from the discharge port 16. This utility model has a reasonable structure. The agitator adopts a double-layer agitator with an upper blade 8 and a lower blade 9. The inside of the vessel body 1 is provided with two layers of extension tubes 5. One layer of extension tube 5 is located between the upper blade 8 and the lower blade 9, and the other layer of extension tube 5 is located above the upper blade 8. First, the double-layer agitator improves the mixing effect. And through the obstruction of the two layers of extension tubes 5, the material is mixed more thoroughly. At the same time, the extension sleeve is connected to the jacket 10 through the fixed sleeve 11, so that the heat exchange medium can smoothly enter the extension tube 5, and heat exchange can also be achieved in the center of the vessel body 1. Moreover, the two layers of extension tubes 5 are staggered, which further improves the heat exchange effect with the material in the middle of the vessel body, thereby ensuring the temperature conditions when mixing sponge raw materials and thus improving the quality of sponge.
