Description

Technical Field

[0001] The utility model relates to the technical field of stirring equipment, in particular to a mixing heating stirrer. Background Art

[0002] As a kind of equipment widely used in chemical, food, medicine and other industries, the core function of the mixer is to achieve uniform mixing of different materials. Among them, the stirring mechanism of the mixer plays a vital role in ensuring uniform mixing of materials and improving production efficiency. Traditional stirring mechanisms usually adopt a single-axis stirring design. Although this design can achieve material mixing to a certain extent, its stirring effect is not ideal when dealing with high-viscosity, easy-to-agglomerate or granular materials. In addition, during the stirring process, the single-axis stirring mechanism often cannot avoid the formation of dead corners near the stirring shaft, resulting in uneven material mixing and affecting product quality.

[0003] In order to overcome these problems, some technicians have tried to introduce a double-axis stirring design into the stirring mechanism. The double-axis stirring mechanism can stir the materials in a wider area through the relative rotation of the two stirring shafts, thereby improving the mixing effect. However, the existing double-axis stirring mechanism still has certain shortcomings in structural design and stirring effect. For example, the configuration of the stirring blades is often relatively simple, and it is difficult to fully adapt to the stirring needs of different materials; in addition, for the mixing processing of materials with a high moisture content, traditional mixers may find it difficult to achieve efficient mixing and unloading. Therefore, it is necessary to provide a new type of mixing and heating mixer to improve the mixing efficiency and mixing uniformity, while better adapting to the processing of materials with a high moisture content.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0036] See also Figure 1-11 , an embodiment provided by the utility model:

A stirring blade assembly is installed on the stirring shaft 2, wherein the stirring blade assembly includes a forward scraping part 3, a stirring part 4, and a reverse scraping part 5. The forward scraping part 3 and the reverse scraping part 5 are respectively installed on the stirring shaft 2 near the two ends, and the stirring part is installed in the middle of the stirring shaft. The stirring part includes a plurality of stirring arms 205 installed around the axis on the stirring shaft, and stirring blades 206 are installed on the stirring arms. The stirring blades are T-shaped, and the ends have a scraping function and the entire blade has a stirring function; the forward scraping part and the reverse scraping part are symmetrically arranged and have opposite scraping directions. The forward scraping part and the reverse scraping part both include a scraping arm 201 installed on the stirring shaft, and a scraping blade 202 is installed on the scraping arm; the scraping blade is L-shaped, and a scraping part 203 and a stirring part 204 are designed on the scraping blade. The scraping part 203 is used to scrape the material on the end wall of the silo and is arranged radially along the stirring shaft.

[0038] As one of the installation design forms, the stirring shaft 2 is equipped with a blade arm fixing seat corresponding to the stirring arm and the scraper arm. The blade arm fixing seat includes an arc sleeve 1 209 and an arc sleeve 210 that are interlocked. The arc sleeve 1 and the arc sleeve 2 are interlocked and sleeved on the stirring shaft 2; the stirring arm and the scraper arm are fixed by the blade arm fixing seat. This design not only simplifies the assembly process, but also improves the stability of the structure. At the same time, the blade arm fixing seat adopts the design of arc sleeve 1 and arc sleeve 2 that are interlocked, which makes the installation and disassembly of the stirring arm and the scraper arm more convenient, and improves the maintainability and flexibility of the equipment; through the combined design of the forward scraper part, the stirring part, and the reverse scraper part, multi-region and multi-position stirring of the material is realized. This design not only improves the uniformity of stirring, but also significantly improves the mixing efficiency, so that the material can reach an ideal mixing state in a short time.

[0039] Furthermore, in this solution, a blade arm isolation sleeve is installed between the two blade arm fixing seats corresponding to the stirring shaft. By providing the blade arm isolation sleeve 211, the friction and collision between the stirring arm 205 and the scraper arm 201 are effectively reduced, thereby extending the service life of the equipment. In addition, this design also reduces the noise and vibration of the equipment during operation, and improves the stability and reliability of the equipment.

[0040] Furthermore, a plurality of stirring blade arms are arranged on the stirring shaft in a spiral line. The specific stirring blade parameters are as follows: the stirring blade has a blade installation angle of 30°-60°, and the stirring blade is detachably installed at the free end of the stirring blade arm, so as to facilitate the adjustment of the extension length of the stirring blade according to the demand; wherein a long waist hole 207 is provided on the stirring blade arm corresponding to the position of the stirring blade along the radial direction of the stirring shaft, and the stirring blade is adjustably installed on the stirring blade arm through the long waist hole, and a positioning plate 208 cooperating with both sides of the stirring blade arm is installed on the back of the stirring blade; the stirring blade adopts a detachable design, which is convenient for cleaning and replacement, and effectively avoids the problems of material residue and cross contamination.

In the actual application of the stirring shaft, two sets of stirring shafts are used in combination to ensure that the stirring blades on the two stirring shafts are staggered in the axial direction to improve the stirring effect. The cross section of the stirring shaft corresponding to the installation position of the stirring blade assembly is square, and the blade arm fixing seat and the blade arm isolation sleeve are provided with installation holes that match the stirring shaft, which enhances the stability and durability of the structure; the frame is provided with packing seals and bearing seats at both ends of the stirring shaft to ensure the sealing and rotation flexibility during the mixing process; through the double-shaft mixing design, the two stirring shafts rotate side by side on the frame, and mesh with each other through gears at one end, so that the two stirring shafts rotate in opposite directions. This design not only expands the mixing range, but also makes the material subject to shear and extrusion from two different directions during the mixing process, thereby improving the mixing efficiency and uniformity.

[0041] In addition, an automatic unloading device is installed on the frame at the position corresponding to the discharge port 11; the automatic unloading device includes a discharge shaft 301 rotatably installed on the frame, and a baffle plate assembly is installed at the position corresponding to the discharge port on the discharge shaft 301, and the baffle plate assembly includes rotating wheels 302 installed side by side on the discharge shaft, and an arc-shaped discharge sealing plate 303 is installed circumferentially between the two rotating wheels, and the outer wall of the arc-shaped discharge sealing plate is fitted and covered with the discharge port. The rotation of the discharge shaft drives the arc-shaped discharge sealing plate to rotate to open or close the discharge port, and a driving source 304 for controlling the rotation of the discharge shaft is installed on the frame. In this embodiment, the driving source adopts a driving cylinder; wherein multiple baffle plate assemblies are installed along the length direction of the discharge shaft; wherein multiple dividing shafts 305 are also installed between the two rotating wheels, and the dividing shafts are installed parallel to the discharge shaft; in order to ensure the overall structural strength, a reinforcing plate is also installed on the inner side of the arc-shaped discharge sealing plate; the design of the automatic unloading device makes the discharge process more convenient and efficient. The discharge port can be easily opened or closed by rotating the discharge shaft on the frame and the baffle assembly. This design not only reduces the tediousness of manual operation, but also improves the efficiency of unloading. The design of the arc-shaped discharge sealing plate makes the discharge port tighter when closed, effectively preventing the leakage of materials during the mixing process. At the same time, the setting of the distribution shaft also helps the uniform distribution and flow of materials, further improving the uniformity of mixing. In addition, it is easy to maintain: the electric heating module adopts a detachable design, which is convenient for the replacement and maintenance of the ceramic heating tube. In addition, the structure of the arc-shaped heating cover and the support plate also makes cleaning and maintenance work simpler and more convenient.

[0042] An electric heating module for heating the inner chamber of the cylindrical hopper is installed on the side wall of the cylindrical hopper. Two groups of electric heating modules are installed and distributed on both sides of the cylindrical hopper.
