Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a drying device for air-entraining agent raw materials. Background Technology

[0002] Air-entraining agents are substances that create pores in a material. They can be broadly classified into three categories: chemical air-entraining agents, physical air-entraining agents, and surfactants. Chemical air-entraining agents are compounds that, upon heating and decomposition, release gases such as carbon dioxide and nitrogen, forming fine pores within the polymer composition. Physical air-entraining agents are formed when the foam pores are created through a change in the physical state of a substance, such as the expansion of compressed gas, the evaporation of liquid, or the dissolution of solid. All air-entraining agents possess high surface activity, effectively reducing the surface tension of liquids and aligning their electron double layers on the liquid film surface to surround air, forming bubbles, which then combine to form foam.

[0003] Drying is the final step in the production of gas-entraining agents, and it directly affects the product yield, the rate of premium grade products, the amount of gas generated by the product, and the consumption of water and steam.

[0004] The existing methods make it difficult to fully heat the air-entraining agent from all sides. Uneven heat distribution prevents the air-entraining agent from achieving optimal drying results, leading to uneven product drying, numerous cracks, low pass rates, and reduced production efficiency. Furthermore, the exhaust vents of existing drying devices carry away a large amount of air-entraining agent material during gas discharge, resulting in raw material losses. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for air-entraining agent raw materials to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drying device for a gas-entraining agent raw material includes a raw material barrel, a material transfer device, an exhaust port, and a fan. The material transfer device is located inside the raw material barrel and is rotatably connected to it. The exhaust port is located at the right end of the raw material barrel and is connected to a drying chamber for removing moisture from the gas. The fan is located at the left end of the raw material barrel and is connected to it. A driving device is provided at the end of the raw material barrel where the fan is located. The driving device is drivenly connected to the material transfer device. The exhaust end of the drying chamber is connected to the inlet end of the fan through a pipe. A heating device is provided on the inner wall of the raw material barrel.

[0008] Furthermore, a sampling and testing port is provided at the bottom of the raw material barrel.

[0009] Furthermore, the material conveying device is a screw conveyor.

[0010] Furthermore, a first lifting rod is provided at the bottom of the drive device.

[0011] Furthermore, a second lifting rod is provided at the bottom of the raw material barrel near the drive device.

[0012] Furthermore, both the first and second lifting rods are connected to an external control center for data transmission, enabling them to move synchronously in coordination.

[0013] Furthermore, the exhaust port is equipped with a filter device.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, to achieve the best drying effect for the air-entraining agent material, ensure uniform drying of the product, increase the pass rate, and improve production efficiency, a heating device is installed inside the raw material barrel, and a fan is installed at the left end of the raw material barrel. This allows the material inside the barrel to be heated to a greater extent through dispersion. The exhaust port is located at the right end of the raw material barrel and is connected to a drying chamber for removing moisture from the gas. The exhaust end of the drying chamber is connected to the inlet end of the fan through a pipe, forming a circulating hot air transfer system. This avoids heat loss and also prevents a large amount of air-entraining agent material from being carried away when the gas is discharged through the exhaust port, thereby saving on raw material losses.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 The present invention provides the following technical solution:

[0021] A drying device for gas-entraining agent raw materials includes a raw material barrel 1, a material transfer device 2, an exhaust port 3, and a blower 4. The material transfer device 2 is located inside the raw material barrel 1 and is rotatably connected to it. The exhaust port 3 is located at the right end of the raw material barrel 1 and is connected to a drying chamber 5 for removing moisture from the gas. The blower 4 is located at the left end of the raw material barrel 1 and is connected to it. A drive device 6 is provided at the end of the raw material barrel 1 where the blower 4 is located. The drive device 6 is connected to the material transfer device 2. The exhaust end of the drying chamber 5 is connected to the inlet end of the blower 4 through a pipe 7. A heating device 8 is provided on the inner wall of the raw material barrel 1.

[0022] In an even better configuration, the bottom of the raw material barrel 1 is equipped with a sampling inspection port 9. To ensure that the material inside the raw material barrel 1 achieves the best drying effect, the material is sampled and inspected at regular intervals to check whether it meets the drying standard. Alternatively, a moisture detector can be installed inside the raw material barrel 1, and the temperature can be better controlled through an external display device.

[0023] Furthermore, the material conveying device 2 is a screw conveyor, which can better push the material. The screw conveyor is hollow inside, which can better cooperate with the fan 4, so that the material in the barrel can be better dispersed and receive the maximum heating range.

[0024] In an even better configuration, the drive unit 6 is equipped with a first lifting rod 10 at the bottom, which allows the drive unit 6 to move up and down and adjust its height to coordinate with the up and down movement of the raw material barrel 1.

[0025] Furthermore, a second lifting rod 11 is provided at the bottom of the raw material barrel 1 near the drive device 6. This allows the material in the raw material barrel 1 to quickly enter the discharge end, and also prevents the material from accumulating in the raw material barrel 1. Additionally, the tilted raw material barrel 1 is easy to clean.

[0026] In a more optimized configuration, both the first lifting rod 10 and the second lifting rod 11 are connected to the external control center via data connection and move synchronously in coordination with each other. This allows the raw material barrel 1 and the drive device 6 to cooperate with each other and rise and fall together through data connection.

[0027] Furthermore, the exhaust port 3 is equipped with a filter device 12 to prevent material loss and uneven heating caused by excessive material entering the exhaust port 3, which would make it difficult to guarantee the quality of the material.

[0028] Working principle: Raw materials enter the raw material tank 1. To ensure the best drying effect of the air-entraining agent, uniform product drying, high qualification rate, and improved production efficiency, an internal heating device 8 is installed to control the overall internal temperature. A fan 4 is located at the left end of the raw material tank 1, which disperses the raw materials in the tank through airflow, allowing for greater contact with the internal heat flow and thus heat drying. After drying, the raw materials will have water vapor evaporation. The exhaust port 3 is located at the right end of the raw material tank 1 and is connected to the drying chamber 5 used to remove moisture from the gas. The exhaust end of the drying chamber 5 is connected to the intake end of the fan 4 through the pipe 7, forming a circulating hot air transfer system. This avoids heat loss and saves energy. At the same time, it also prevents a large amount of air-entraining agent material from being carried away when the gas is discharged from the exhaust port 3, thus avoiding the loss of raw materials.
