Description

Technical Field

[0001] This utility model relates to the field of powder mixing and preparation, and in particular to an apparatus for mixing and preparing slurries from powders. Background Technology

[0002] With the continuous advancement of technology, modern society has increasingly higher requirements for environmental protection and safety, prompting continuous improvements in powder mixing and slurry preparation equipment. On the one hand, the equipment has better sealing performance to prevent powder leakage and reduce harm to the environment and operators; on the other hand, greater emphasis is placed on environmental protection in material selection and process design to reduce energy consumption and waste generation.

[0003] Most existing powder mixing and slurry preparation devices achieve slurry preparation through simple stirring. Some of these devices are used for slurries that are easily oxidized or volatile. Easily oxidized slurries usually contain oxygen-sensitive components and are prone to oxidation reactions when exposed to air or high temperatures, leading to performance degradation, discoloration, or the production of harmful substances. However, when preparing easily oxidized or volatile slurries, traditional preparation equipment has poor sealing and cannot effectively introduce and maintain an inert gas environment, resulting in oxidation, deterioration, or volatilization loss.

[0012] The bottom of the processing cylinder is fixedly connected to a support leg, which abuts against the mounting base plate. The processing cylinder and the support leg are integrally formed.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] The apparatus for mixing powder to prepare slurry uses a processing cylinder that can achieve complete sealing. The main air inlet pipe on the processing cylinder facilitates the introduction of inert gas and detection gas into the processing cylinder.

It includes a processing cylinder 1 and an adjusting rod 6 rotatably connected inside the processing cylinder 1. The processing cylinder 1 serves as the core container of the entire apparatus, used to contain powders and solutions and to carry out the mixing and preparation of slurries. Its completely sealed design effectively prevents the entry of outside air, providing an oxygen-free or specific gas environment for the preparation of easily oxidized or volatile slurries, avoiding oxidation, deterioration, or volatilization loss of the slurry. When preparing easily oxidized or volatile slurries, the required powder is added to the processing cylinder 1 through the feed pipe 5, and the solution is also introduced into the processing cylinder 1 in a corresponding manner. Subsequent operations such as stirring and introducing inert gas are all completed inside the processing cylinder 1.

[0023] A fixing ring 63 is fixedly connected to the bottom of the adjusting rod 6. The fixing ring 63 is rotatably connected inside the processing cylinder 1. A stirring element is installed on the adjusting rod 6. The adjusting rod 6 is the key component that drives the stirring element to rotate. By rotating, the stirring rod 61 and the inner wall cleaning rod 62 move, thereby completing the stirring and mixing of powder and solution inside the processing cylinder 1, as well as the cleaning of the inner wall of the processing cylinder 1. The fixing ring 63 serves to support the adjusting rod 6 and is also equipped with a sealing element between it and the processing cylinder 1 to ensure the airtightness of the processing cylinder 1 and prevent gas leakage. Two sets of feed pipes 5 are fixedly connected to the processing cylinder 1. The feed pipes 5 are used to transport powder raw materials into the processing cylinder 1 and are the channels for materials to enter the processing cylinder 1. The powder to be prepared into the processing cylinder 1 is added through the feed pipes 5, and the amount added is controlled according to actual needs. Each feed pipe 5 is equipped with a control valve 51. Control valve 51 is used to control the opening and closing of feed pipe 5, thereby precisely controlling the time and flow rate of powder raw materials entering processing cylinder 1. A discharge pipe 3 is fixedly connected to the bottom of processing cylinder 1. The discharge pipe 3 is used to discharge the processed slurry from processing cylinder 1 and is the slurry output channel. A discharge valve 31 is installed on discharge pipe 3. After the slurry is prepared, the discharge valve 31 is opened, and the slurry flows out of processing cylinder 1 through discharge pipe 3. Nitrogen gas is introduced into processing cylinder 1 during discharge to accelerate the discharge speed. A pressure gauge 7 is installed on processing cylinder 1 to detect the pressure inside processing cylinder 1. When processing cylinder 1 is used after a long period of shutdown, a certain amount of air is introduced into processing cylinder 1. By observing the reading of pressure gauge 7, the sealing performance of processing cylinder 1 can be quickly tested. When inert gas is introduced, the pressure change inside processing cylinder 1 can also be monitored in real time.

[0024] A main air inlet pipe 4 is fixedly connected to the processing cylinder 1. A guide block 41 is installed at the right end of the main air inlet pipe 4. Two sets of air inlet pipes 42 are installed at the right end of the guide block 41. A one-way valve 43 is installed on the air inlet pipe 42. The main air inlet pipe 4, the guide block 41, the air inlet pipes 42 and the one-way valve 43 serve as the main channel for introducing gas into the processing cylinder 1, which facilitates the centralized introduction of gas. The nitrogen supply pipe and the air filling pipe are respectively connected to the two sets of air inlet pipes 42 on the guide block 41. The gas enters the processing cylinder 1 through the main air inlet pipe 4.

[0025] A second pulley 64 and a retaining ring 63 are fixedly connected to the outer peripheral wall of the adjusting rod 6.

[0026] The bottom of the processing cylinder 1 is provided with a mounting base plate 2, on which a motor body 21 is mounted. A second pulley 64 is fixedly connected to the output end of the motor body 21. A connecting belt 23 is provided between the second pulley 64 and the first pulley 22. When the motor body 21 is started, the first pulley 22 at its output end drives the second pulley 64 on the adjusting rod 6 to rotate through the connecting belt 23, thereby causing the adjusting rod 6 to rotate.

[0027] The mixing component includes a stirring rod 61 and an inner wall cleaning rod 62. Both the stirring rod 61 and the inner wall cleaning rod 62 are fixedly connected to the outer peripheral wall of the adjusting rod 6. The inner wall cleaning rod 62 abuts against the bottom of the processing cylinder 1. The stirring rod 61 and the inner wall cleaning rod 62 rotate with the rotation of the adjusting rod 6, stirring the powder and solution in the processing cylinder 1 to mix them thoroughly and form a uniform slurry. When the adjusting rod 6 rotates, the stirring rod 61 continuously stirs the powder and solution in the processing cylinder 1, causing them to blend together and gradually form a slurry that meets the requirements. The inner wall cleaning rod 62 can scrape off the powder or slurry adhering to the inner wall of the processing cylinder 1 to prevent material residue from affecting the slurry quality and subsequent use.

[0028] A sealing element is provided between the retaining ring 63 and the processing cylinder 1.

[0029] The adjusting rod 6, stirring rod 61, inner wall cleaning rod 62 and fixing ring 63 are integrally molded.

[0031] Example 1: This utility model provides a device for mixing powder to prepare slurry, which has the function of detecting the airtightness of the processing cylinder 1. The processing cylinder 1 is a completely sealed design, which can effectively prevent the entry of external air and provide a stable environment for slurry preparation. A pressure gauge 7 is installed on the device to detect the pressure inside the processing cylinder 1. When the processing cylinder 1 is used again after a long period of shutdown, a certain amount of air can be introduced into it. By observing the reading of the pressure gauge 7, the airtightness of the processing cylinder 1 can be quickly determined. When an inert gas (such as nitrogen) is introduced into the processing cylinder 1 for slurry preparation, the pressure gauge 7 can also monitor the pressure change inside the processing cylinder 1 in real time to ensure the safety and stability of the operation process. In addition, the main air inlet pipe 4, the guide block 41, the air inlet pipe 42 and the one-way valve 43 constitute the main channel for introducing gas into the processing cylinder 1. The nitrogen supply pipe and the air filling pipe are respectively connected to the two sets of air inlet pipes 42 on the guide block 41. The gas enters the processing cylinder 1 through the main air inlet pipe 4, providing gas support for detecting airtightness and subsequent slurry preparation operations.

[0032] Example 2: In the slurry preparation device of this utility model, during slurry preparation, the required powder is added into a completely sealed processing cylinder 1 through a feed pipe 5 equipped with a control valve 51. Simultaneously, a solvent is introduced. A mounting base plate 2 is installed at the bottom of the processing cylinder 1, on which a motor body 21 is mounted. The first pulley 22 at the output end of the motor body 21 drives the second pulley 64 on the adjusting rod 6 to rotate via a connecting belt 23, causing the adjusting rod 6 to rotate. A stirring component, including a stirring rod 61 and an inner wall cleaning rod 62, is fixedly connected to the outer peripheral wall of the adjusting rod 6. These components rotate with the adjusting rod 6, stirring and mixing the powder and solution to form a uniform slurry. The inner wall cleaning rod 62 also scrapes away residual material from the inner wall of the processing cylinder 1. After slurry preparation, the discharge valve 31 on the discharge pipe 3 is opened, and the slurry flows out. Introducing nitrogen gas into the processing cylinder 1 during discharge can accelerate the discharge speed. The adjusting rod 6, stirring rod 61, inner wall cleaning rod 62 and fixing ring 63 are integrally molded. The processing cylinder 1 and support leg 11 are also integrally molded. A sealing element is provided between the fixing ring 63 and the processing cylinder 1 to ensure the sealing of the device.
