Abstract
Description
Technical Field
[0001] This invention belongs to the field of mixing equipment, specifically a constant temperature mixer for wet powder and its processing method. Background Technology
[0002] In the mixing and processing of wet powder materials, temperature control and mixing uniformity are key factors affecting product quality. Traditional mixing equipment often suffers from problems such as poor temperature control, insufficient mixing, and wet powder easily adhering to the tank walls, leading to uneven mixing and material waste. Some mixers only regulate the temperature of the tank through external heating, resulting in low heat transfer efficiency and uneven temperature distribution within the tank. This can easily cause localized overheating or underheating of the powder, affecting the physicochemical properties of the material. During the mixing process, the unidirectional mixing structure makes it difficult to achieve multidimensional movement of the material, resulting in mixing dead zones. Furthermore, due to their high moisture content, wet powder easily adheres to the tank walls during mixing, which not only reduces mixing efficiency but also requires regular manual cleaning, increasing operating costs and labor intensity.
[0003] In summary, the present invention provides a constant temperature mixer for wet powder and its processing method to solve the above-mentioned problems. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention provides a constant temperature mixer for wet powder and its processing method, thereby solving the problems in the prior art where wet powder easily adheres to the tank wall due to its high humidity during the mixing process, which not only reduces mixing efficiency but also requires regular manual cleaning.
[0005] A constant-temperature mixer for wet powder includes a mixing base frame, a mixing side frame vertically mounted at one end of the mixing base frame, a constant-temperature tank mounted on the mixing base frame via a tank mounting bracket, a bevel gear disk rotatably connected to one side of the mixing side frame, a rotary cylinder mounted on the side of the mixing side frame away from the bevel gear disk, a rotary shaft fixedly connected to the output end of the rotary cylinder, one end of the rotary shaft movably passing through the mixing side frame and extending into the constant-temperature tank, a stirring plate mounted on the end of the rotary shaft inserted into the constant-temperature tank, a synchronous bevel gear mounted on one side of the bevel gear disk, a gear shaft fixedly connected to the center of the synchronous bevel gear, a synchronous roller one fixedly connected to one end of the gear shaft, a rotating shaft rotatably connected to the bottom of the constant-temperature tank, one end of the rotating shaft inserted into the constant-temperature tank, a synchronous roller two fixedly connected to the other end of the rotating shaft, the synchronous roller one and the synchronous roller two being connected by a synchronous belt drive, and multiple scraper plates fixedly connected to the surface of the rotating shaft.
[0006] Furthermore, a matching limiting ring is installed on one side of the bevel gear disk, and a positioning ring is installed on the mixing side frame, with the positioning ring slidably sleeved on the surface of the matching limiting ring.
[0007] Furthermore, the rotating shaft is rotatably connected to the side wall of the constant temperature tank, and the rotating shaft passes through the center of the bevel gear disk and is fixedly connected to the bevel gear disk.
[0008] Furthermore, the bevel gear disk meshes with a synchronous bevel gear, and the gear shaft is rotatably mounted on the surface of the mixing side frame via a bushing.
[0009] Furthermore, the rotating shaft is located at the middle position of the bottom of the constant temperature tank, and the scraper is fixedly connected to one end of the rotating shaft that is inserted into the constant temperature tank.
[0010] Furthermore, the scraper is arranged along the shape of the side wall of the constant temperature tank, the scraper is in movable contact with the side wall of the constant temperature tank, and the scraper is located below the rotating shaft and does not contact the rotating shaft.
[0011] Furthermore, the tank mounting bracket is installed on the side wall of the constant temperature tank, and the tank mounting bracket is vertically installed on the surface of the mixing base.
[0012] Furthermore, the top of the constant temperature tank is an open structure and is equipped with a tank lid, and the bottom of the constant temperature tank is equipped with a discharge pipe.
[0013] A method for processing wet powder materials using a constant temperature mixer includes the following steps: Step 1: Open the lid, add powder into the thermostatic container, close the lid. Heating wires are installed between the inner wall layers of the thermostatic container, which can directly heat the container and maintain a constant internal temperature. Step 2: Start the rotary cylinder. The rotary cylinder drives the rotary shaft to rotate, which in turn causes the bevel gear disk to rotate. The synchronous bevel gear meshing on the surface of the bevel gear disk drives the gear shaft to rotate. Synchronous roller one and synchronous roller two rotate simultaneously, and the rotary shaft and the rotating shaft are driven synchronously. Step 3: The scraper is driven by a rotating shaft, which in turn drives the mixing plate to rotate. While mixing, it prevents the powder inside from becoming too wet and adhering to the wall of the constant temperature tank. The scraper removes the wet powder from the tank wall. Step 4: After mixing is complete, discharge the mixture through the bottom outlet pipe.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a rotary cylinder to drive a rotating shaft. This shaft not only drives the stirring plate to mix the wet powder material in the constant temperature tank, but also, through the meshing of a bevel gear disc and a synchronous bevel gear, and the linkage of synchronous roller one, synchronous belt, and synchronous roller two, drives the rotating shaft located at the bottom of the constant temperature tank to rotate synchronously. This, in turn, drives the scraper to rotate along the side wall of the constant temperature tank. This synchronous drive structure allows the stirring and scraping actions to be performed in tandem. While the stirring plate is thoroughly mixing the material, the scraper can promptly remove the wet powder material adhering to the tank wall, effectively preventing the material from sticking and clumping due to excessive moisture. This ensures the uniformity and thoroughness of the material mixing, and also improves the space utilization rate of the constant temperature tank and the material output rate.
[0015] 2. This invention, by incorporating heating wires within the inner wall jacket of the thermostatic tank, enables direct heating of the tank's interior. This design allows for rapid and uniform temperature increases within the tank, ensuring the wet powder remains within the set temperature environment throughout the mixing process. Compared to traditional external heating methods, this reduces heat loss during transfer, improves heating efficiency, and allows for more precise temperature control within the tank. It also prevents temperature fluctuations from adversely affecting the physical properties and mixing effect of the wet powder, providing a reliable temperature guarantee for stable mixing of the wet powder.
[0016] 3. This invention achieves precise positioning and stable support for the bevel gear disk through a sliding sleeve structure of a matching limiting ring and a positioning ring. When the bevel gear disk rotates under the drive of the rotating shaft, the matching limiting ring slides smoothly along the inner wall of the positioning ring, effectively preventing radial offset or wobbling of the bevel gear disk during rotation. This ensures that the bevel gear disk and the synchronous bevel gear always maintain an accurate meshing state, thereby guaranteeing the stability and reliability of power transmission, avoiding problems such as noise, vibration, and component wear caused by poor gear meshing, and extending the service life of the equipment.
