Description

Technical Field

[0001] This application relates to the field of cement production technology, specifically to a polyol amine raw material preparation device. Background Technology

[0002] In cement production, grinding aids, reinforcing agents, and other chemical admixtures play a crucial role in improving grinding efficiency, optimizing cement performance, and reducing energy consumption. Polyol amine compounds (such as triethanolamine and triisopropanolamine) are one of the core raw materials for these admixtures. Their efficiency and quality in mixing with other components (such as polyols, salt solutions, and fatty acids) to prepare the final product directly determine the performance and production cost of the admixture.

[0003] Polyol amine raw materials need to be formed by mixing various liquid raw materials and powders. At present, the powder and liquid raw materials are added into the mixing tank at one time and stirred. Some powder cannot be dissolved in time and settles at the bottom of the mixing tank. The vortex formed by the stirring shaft is used to swirl up the powder settled at the bottom and slowly dissolve it. This process takes a long time and results in a low overall mixing rate. Utility Model Content

[0004] In view of the above problems, this application provides a polyol amine raw material preparation device that can accelerate the mixing speed of polyol amine raw materials.

[0005] According to one aspect of the embodiments of this application, a polyol amine raw material preparation apparatus is provided. The polyol amine raw material preparation apparatus includes a mixing tank and a feeding cylinder located above the mixing tank. A rotating motor is connected to the upper part of the mixing tank via a support. A stirring shaft extending from and rotatably connected to the lower part of the rotating motor is driven by the rotating motor and is connected to the bottom wall of the mixing tank. Multiple stirring blades are connected to the outer periphery of the stirring shaft. A discharge pipe is connected to one side of the bottom of the mixing tank, and a discharge valve is provided at the discharge pipe. The feeding cylinder includes a cylinder body connected to the mixing tank via a support base. The bottom of the cylinder body is projected into the mixing tank. Multiple feeding holes are provided at the lower part of the cylinder body. A disc is rotatably disposed above the inner bottom wall of the cylinder body. A notch is provided on one side of the disc. A drive shaft is connected to the central axis of the disc, and a drive device is connected to the drive shaft.

[0006] In some embodiments, a reversing cylinder is sleeved around the outer periphery of the drive shaft, and at least two bearings are connected between the inner wall of the reversing cylinder and the drive shaft. Multiple feeding plates are connected to the outer wall of the reversing cylinder, and the drive device is used to drive the reversing cylinder and the drive shaft to rotate in opposite directions.

[0007] In some embodiments, the power for the drive device comes from the rotating motor.

[0008] In some embodiments, the driving device includes a first sprocket and a second sprocket connected by a chain link drive. The first sprocket is fixed to the outer periphery of the stirring shaft. The top and bottom ends of the second sprocket are coaxially connected to a third sprocket and a first gear, respectively. A fourth sprocket is provided on the outer periphery of the driving shaft. The fourth sprocket is connected to the third sprocket by a chain link. A second gear that meshes with the first gear is provided on the outer periphery of the reversing cylinder.

[0009] In some embodiments, the support base includes a first support extending below the first gear, the first gear being rotatably mounted on the first support, a second support connected to the support, and the top ends of the drive shaft and the third sprocket being rotatably mounted below the second support.

[0010] In some embodiments, a guide chute is inclinedly provided on one side of the top of the mixing tank, and the lower end of the guide chute is inclined and extends into the body of the cylinder.

[0011] The beneficial effects of this application are as follows: By storing the powdered raw materials in a feeding cylinder and gradually adding them to the mixing tank, the problem of powder accumulating at the bottom of the mixing tank due to excessive addition at one time, and the slow flow rate at the bottom of the mixing tank caused by the minimal influence of the stirring blades, thus preventing the powder from dissolving quickly, can be avoided. Furthermore, by providing feeding holes at the bottom of the cylinder body and a disc inside the cylinder body with notches, the disc can block the feeding holes, preventing material from being poured into the mixing tank all at once. As the disc rotates, the notches sequentially align with multiple feeding holes for material feeding, resulting in a stable and uniform feeding process.

Figure 6This is a partial structural diagram of the disc provided in an embodiment of this application. The polyol amine raw material preparation device 100 includes a mixing tank 110 and a feeding cylinder 120 located above the mixing tank 110. The feeding cylinder 120 is used to uniformly and slowly feed powder into the mixing tank 110, wherein the powder includes sodium thiosulfate powder and sodium lignosulfonate powder, etc. Liquid raw materials can be directly poured into the mixing tank 110 or pumped into the mixing tank 110 by a water pump. Liquid raw materials include glycerol, triethanolamine and water. A rotating motor 140 is connected above the mixing tank 110 via a support 130. The support 130 is used to support and install the rotating motor 140 and the stirring shaft 141. The specific shape, size and material of the support 130 can be set according to actual needs, as long as it meets the usage requirements, and there are no restrictions here. A stirring shaft 141 extends and is rotatably connected to the bottom wall of the mixing tank 110 via a drive connection below the rotating motor 140. Multiple stirring blades 142 are connected to the outer periphery of the stirring shaft 141. When the rotating motor 140 is turned on, it drives the stirring shaft 141 and the multiple stirring blades 142 to rotate, thereby completing the mixing of various raw materials inside the mixing tank 110. A discharge pipe 111 is connected to one side of the bottom of the mixing tank 110, and a discharge valve 112 is installed at the discharge pipe 111. After mixing is completed, the discharge valve 112 can be opened to discharge the material. The material distribution cylinder 120 includes a cylinder body 121, which is connected to the mixing tank 110 via a support base 122. Before starting the equipment, the powder needs to be poured into the cylinder body 121 for temporary storage. The bottom projection of the cylinder body 121 is located within the mixing tank 110. Multiple material distribution holes 123 are provided below the cylinder body 121, through which powder can be discharged into the mixing tank 110. The distribution holes 123 should be arranged according to the principle of "large and sparse" to avoid the problem of powder clumping due to rising water vapor below, preventing it from passing smoothly through the distribution holes 123. A disc 124 is rotatably mounted on the inner bottom wall of the cylinder body 121. A notch 124a is provided on one side of the disc 124. A drive shaft 125 is connected to the central axis of the disc 124, and a drive device 150 is connected to the drive shaft 125. The drive device 150 drives the drive shaft 125 to rotate, which in turn drives the disc 124 to rotate. During the rotation of the disc 124, when the notch 124a aligns with the material distribution hole 123, the material inside the cylinder body 121 can be discharged into the mixing tank 110 through the material distribution hole 123.

[0017] In this embodiment, during operation, liquid raw materials are added to the mixing tank 110, and powder is temporarily stored in the cylinder body 121. Then, the rotating motor 140 is started, which drives the stirring shaft 141 and stirring blades 142 to rotate for mixing. Simultaneously, the driving device 150 drives the driving shaft 125 and the disc 124 to rotate. When the notch 124a of the disc 124 is aligned with the corresponding material distribution hole 123, the powder particles inside the cylinder body 121 will pass through the notch 124a and the material distribution hole 123 and fall into the mixing tank 110, where they are mixed evenly with the rotation of the stirring shaft 141 and stirring blades 142.

[0018] As can be seen from the above, in this embodiment, by setting up a feeding cylinder 120 to store the powder raw materials and gradually adding the powder raw materials to the mixing tank 110, the problem of powder accumulating at the bottom of the mixing tank 110 due to excessive powder addition at one time can be avoided. The bottom of the mixing tank 110 is less affected by the stirring blades 142, resulting in a slow flow rate and preventing the powder from dissolving quickly can be avoided. In this application, by setting a feeding hole 123 below the cylinder body 121 and a disc 124 inside the cylinder body 121, and opening a notch 124a at the disc 124, the disc 124 can block the feeding hole 123 to prevent material from being poured into the mixing tank 110 all at once. As the disc 124 rotates, the notch 124a will sequentially align with multiple feeding holes 123 for material feeding, resulting in a stable and uniform feeding process.

[0019] In some embodiments, a reversing cylinder 126 is sleeved around the outer periphery of the drive shaft 125. At least two bearings are connected between the inner wall of the reversing cylinder 126 and the drive shaft 125. A plurality of material feeding plates 126a are connected to the outer wall of the reversing cylinder 126. The drive device 150 is used to drive the reversing cylinder 126 and the drive shaft 125 to rotate in opposite directions. In this embodiment, with the above arrangement, the reversing cylinder 126 and the drive shaft 125 rotate in opposite directions. Since the material feeding plates 126a and the disc 124 are respectively connected to the reversing cylinder 126 and the drive shaft 125, the disc 124 and the material feeding plates 126a rotate in opposite directions. This avoids the problem of powder accumulating above the disc 124 and not being discharged in time due to the continuous rotation of the disc 124. Furthermore, the opposite rotation direction of the material feeding plates 126a and the disc 124 can accelerate the feeding process.

[0020] In some embodiments, the power of the drive device 150 comes from the rotary motor 140. In this embodiment, the drive device 150 is powered by the rotary motor 140. When the rotary motor 140 is turned on, the drive device 150 will be forcibly started. This saves the operator the step of turning on the drive device 150, thus simplifying the operation process, and also reduces the purchase cost of equipment components.

[0021] In some embodiments, the drive device 150 includes a first sprocket 151 and a second sprocket 152 connected by a chain link. The first sprocket 151 is fixed to the outer periphery of the stirring shaft 141. The top and bottom ends of the second sprocket 152 are coaxially connected to a third sprocket 153 and a first gear 155, respectively. A fourth sprocket 154 is provided on the outer periphery of the drive shaft 125. The fourth sprocket 154 is connected to the third sprocket 153 by a chain link. A second gear 156 that meshes with the first gear 155 is provided on the outer periphery of the reversing cylinder 126. To more clearly illustrate this solution, this application embodiment presents a specific configuration of the drive device 150. During operation, when the rotating motor 140 is turned on and drives the stirring shaft 141 to rotate, the stirring shaft 141 will further drive the first sprocket 151 to rotate. The first sprocket 151 drives the second sprocket 152, the third sprocket 153, and the first gear 155 to rotate through the chain link. The third sprocket 153 and the first gear 155 are fixedly connected to the second sprocket 152, so their rotation directions are the same. However, the third sprocket 153 is connected to the fourth sprocket 154 through the chain link, and the first gear 155 and the second gear 156 mesh. Therefore, the second gear 156 and the fourth sprocket 154 rotate in opposite directions. Furthermore, the rotation directions of the stirring shaft 141 and the reverse cylinder 126 will be opposite.

[0022] In some embodiments, the support base 122 includes a first support 122a extending below the first gear 155, the first gear 155 being rotatably mounted on the first support 122a. A second support 122b is connected to the support 130, and the top ends of the drive shaft 125 and the third sprocket 153 are rotatably mounted below the second support 122b. In this embodiment, the first support 122a and the second support 122b are used to connect the various components to further enhance the overall stability of the device.

[0023] In some embodiments, a guide chute 160 is inclinedly provided on one side of the top of the mixing tank, and the lower end of the guide chute 160 is inclined and extends into the cylindrical body 121. In this embodiment, materials can be quickly discharged into the cylindrical body 121 through the guide chute 160.
