Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, and in particular to a double-layer mixing tank with heat preservation and heating functions. Background Technology

[0002] In continuous production in industries such as food, pharmaceuticals, and chemicals, it is often necessary to heat and stir materials with high viscosity, easy to stick to the wall, or high solid content. Traditional single-layer cylinders rely solely on external heaters on the cylinder wall for direct heat transfer. The cylinder has a large heat dissipation area and serious heat loss, resulting in high energy consumption, large temperature gradient, and easy local overheating or cooling and agglomeration of materials.

[0003] Existing technologies typically employ single-layer cylindrical or single-conical silos, with electric heating belts wrapped around the outer walls or steam-heated jackets. A stirring paddle extends from the top for radial mixing. After material is fed in through the top inlet, the paddle rotates at a constant speed to attempt to mix the material evenly. However, when processing high-viscosity colloids or materials containing solid particles, the radial flow field of the single paddle can easily create dead zones at the bottom and conical sections. Simultaneously, the paddle blades cannot reach the cylinder wall, leading to continuous material adhesion, increased thermal resistance, localized temperature rise on the cylinder wall, and the formation of a charred layer. As the operating time increases, the charred layer thickens, the heat transfer coefficient decreases, and energy consumption rises sharply. After each batch is completed, the manhole must be opened for manual scraping and cleaning of the walls, posing a risk of high-temperature burns and resulting in poor product consistency.

[0004] Therefore, this utility model provides a double-layer mixing cylinder with heat preservation and heating functions. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a double-layer mixing cylinder with heat preservation and heating functions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a double-layer stirring cylinder with heat preservation and heating function, including an outer frame and a heating component, wherein the heating component includes an outer funnel fixedly connected inside the outer frame, an inner funnel fixedly connected inside the outer funnel, and a heater fixedly connected outside the outer funnel.

[0007] A stirring assembly includes a top cover fixedly connected to the top of an outer frame, a stirring rod rotatably connected inside the top cover, a stirring blade fixedly connected to the top outer side of the stirring rod, a spiral blade fixedly connected to the bottom inner side of the stirring rod, and a wall cleaning assembly fixedly connected to the outside of the stirring assembly.

[0008] In a preferred embodiment, the wall cleaning assembly includes a connecting rod fixedly connected to the outside of the stirring rod.

[0009] In a preferred embodiment, a wall-cleaning plate is fixedly connected to the outer side of the connecting rod at a position parallel to the stirring blade, and an inclined plate is fixedly connected to the outer side of the stirring rod at a position parallel to the spiral blade.

[0010] In a preferred embodiment, the outer side of the cleaning plate is rotatably connected to the inner wall of the inner funnel, and the outer side of the tilting plate is rotatably connected to the inner wall of the inner funnel.

[0011] In a preferred embodiment, a motor is mounted on the top of the top cover, and the drive end of the motor is fixedly connected to the stirring rod.

[0012] In a preferred embodiment, a feed inlet is fixedly connected to the outer top of the inner funnel.

[0013] In a preferred embodiment, a discharge port is fixedly connected to the outer bottom end of the inner funnel.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This utility model 1. Drives the stirring rod to rotate via a motor, which in turn drives the stirring blades, spiral blades, and connecting rod to rotate. The connecting rod drives the wall-cleaning blades to rotate, and simultaneously the stirring rod drives the tilting blades to rotate. The heater transfers heat from the outer funnel to the inner funnel. This design achieves uniform heating of the material while stirring, and can remove the material adhering to the inner wall, improving material processing efficiency and quality. In contrast to the background technology, it solves the problems of large heat loss, high energy consumption, and large temperature gradient in traditional single-layer material cylinders, and also avoids the dead zones at the bottom and conical section caused by single-blade radial stirring.

[0016] 2. By using the cleaning blades and tilting blades to scrape away material from the inner walls of the upper and lower parts of the inner funnel, the design achieves real-time cleaning of material adhering to the cylinder wall, preventing increased thermal resistance and local temperature rise of the cylinder wall, reducing material scorching, and avoiding the problems of thickened scorch layer, decreased heat transfer coefficient, and sudden increase in energy consumption caused by the blades not being able to reach the cylinder wall.

[0028] 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.

[0029] like Figure 1 as well as Figure 3As shown, this embodiment provides a technical solution: a double-layer mixing drum with heat preservation and heating functions, including an outer frame 1 and a heating component 2. The heating component 2 includes an outer funnel 21 fixedly connected inside the outer frame 1, an inner funnel 22 fixedly connected inside the outer funnel 21, a heater 23 fixedly connected to the outer side of the outer funnel 21, and a feed inlet 5 fixedly connected to the top outer side of the inner funnel 22. A discharge outlet 6 is fixedly connected to the bottom outer side of the inner funnel 22. The outer frame 1 serves as the supporting frame for the entire equipment, fixing and connecting all components such as the heating component 2 and the mixing component 3, ensuring the stability of the overall structure of the equipment, providing a stable installation foundation for each component, preventing displacement or shaking of the equipment due to vibration during operation, and improving the safety of equipment operation. The outer funnel 21 and the inner funnel 22 form a double-layer structure. The interlayer space can be used for heat preservation or to cooperate with the heater 23 to achieve heat transfer, while also protecting the inner funnel 22. The double-layer structure reduces heat exchange between the inner funnel 22 and the outside, enhances the heat preservation effect, and reduces energy consumption. The shape guides the material to gather at the bottom, which facilitates the mixing and discharge of the material and improves the material processing efficiency. The inner funnel 22 directly contains the material to be mixed and heated. It is the main space for the material to carry out the mixing reaction and be heated. The smooth inner wall can reduce material residue, ensure uniform mixing of the material, and improve the material utilization rate. The heater 23 is installed on the outside of the outer funnel 21 and transfers heat to the material in the inner funnel 22 through heat conduction to meet the heating or heat preservation requirements of the material. The feed port 5 is located at the top of the outer side of the inner funnel 22 as the channel for the material to enter the inner funnel 22. The discharge port 6 is located at the bottom of the outer side of the inner funnel 22 and is used to discharge the material that has been mixed and heated out of the equipment.

[0030] like Figures 2-5As shown, the mixing assembly 3 includes a top cover 35 fixedly connected to the top of the outer frame 1. A mixing rod 31 is rotatably connected inside the top cover 35. A mixing blade 32 is fixedly connected to the outer top of the mixing rod 31, and a spiral blade 33 is fixedly connected to the inner bottom of the mixing rod 31. A motor 34 is mounted on the top of the top cover 35, and the drive end of the motor 34 is fixedly connected to the mixing rod 31. The top cover 35, fixed to the top of the outer frame 1, closes the top opening of the inner funnel 22 and provides mounting support for the mixing rod 31 and the motor 34, preventing material from splashing during mixing, reducing material loss and pollution of the operating environment. The mixing rod 31 serves as the transmission shaft for mixing power, connecting the motor 34, the mixing blade 32, and the spiral blade 33. The rotational power of the motor 34 is transmitted to the stirring component. The stirring blade 32 is installed on the outer top of the stirring rod 31 and rotates with the stirring rod 31 to quickly disperse the newly entered material, prevent the material from clumping and accumulating, lay the foundation for deeper stirring at the bottom, and improve the overall stirring uniformity. The spiral blade 33 is distributed in a spiral shape at the bottom of the stirring rod 31. When rotating, it can not only stir the material at the bottom, but also push the material upward through the spiral structure to form an up-and-down circulating stirring effect, which solves the problem of easy sedimentation and uneven stirring of the bottom material in traditional stirring, and realizes the overall mixing of the material from the bottom to the top. The motor 34, as the power source of the stirring component 3, drives the stirring rod 31 to rotate through the drive end, providing power to the stirring blade 32 and the spiral blade 33.

[0031] like Figure 3 as well as Figure 4As shown, a wall-cleaning component 4 is fixedly connected to the outer side of the stirring assembly 3. The wall-cleaning component 4 includes a connecting rod 41 fixedly connected to the outer side of the stirring rod 31. A wall-cleaning plate 42 is fixedly connected to the outer side of the connecting rod 41 at a position parallel to the stirring blade 32, and an inclined plate 43 is fixedly connected to the outer side of the stirring rod 31 at a position parallel to the spiral blade 33. The outer side of the wall-cleaning plate 42 is rotatably connected to the inner wall of the inner funnel 22, and the outer side of the inclined plate 43 is rotatably connected to the inner wall of the inner funnel 22. The connecting rod 41 connects the stirring rod 31 with the wall-cleaning plate 42 and the inclined plate 43, transmitting the rotational force of the stirring rod 31 to the wall-cleaning component, ensuring that the wall-cleaning plate 42 rotates synchronously with the stirring rod 31. The wall-cleaning plate 42 is installed on the outer side of the connecting rod 41, parallel to the stirring blade 32. When it rotates with the stirring rod 31, its outer side is in close contact with the upper inner wall of the inner funnel 22, scraping off the material adhering to the inner wall, preventing the material from accumulating, clumping, or deteriorating on the upper part of the inner wall, and maintaining... To ensure all materials participate in the mixing and improve material utilization, the inclined blade 43 is installed on the outside of the mixing rod 31, parallel and inclined to the spiral blade 33. When rotating, it closely adheres to the lower inner wall of the inner funnel 22, scraping off the material attached to the bottom and inclined parts. For the funnel-shaped inclined structure at the bottom of the inner funnel 22, the inclined blade 43 can accurately fit the inner wall, removing residual material in corners that are difficult to reach by traditional mixing, further ensuring the uniformity of mixing. With the pushing action of the spiral blade 33, the scraped material is rolled back into the mixing cycle, while assisting the material to move towards the discharge port 6, reducing residue during discharge.

[0032] Working principle:

[0033] When using: such as Figure 1 As shown, first, the motor 34 is started, and the drive end of the motor 34 will drive the stirring rod 31 to start rotating; then the stirring rod 31 will simultaneously drive the stirring blade 32 at its outer top, the spiral blade 33 at its inner bottom, and the connecting rod 41 on the outside to rotate synchronously, as detailed in [link to details]. Figure 3 When the connecting rod 41 rotates, the cleaning plate 42, which is parallel to the stirring blade 32 on its outer side, will rotate accordingly. Simultaneously, the inclined plate 43, which is parallel to the spiral blade 33 on the outer side of the stirring rod 31, will also rotate. See details... Figure 3 as well as Figure 4 As shown; when the cleaning blade 42 rotates, its outer side rotates on the upper inner wall of the inner funnel 22, and when the tilting blade 43 rotates, its outer side rotates on the lower inner wall of the inner funnel 22. At the same time, the heater 23 starts to work, transferring heat to the inner funnel 22 through the outer funnel 21. When the material enters the inner funnel 22 from the feed port 5, the rotating stirring blade 32 performs preliminary stirring and dispersion on the upper material, and the spiral blade 33 stirs the bottom material and pushes it upward to form a circulation. The cleaning blade 42 and the tilting blade 43 scrape off the material attached to the upper and lower inner walls of the inner funnel 22 respectively. Finally, the material that has been stirred and heated is discharged from the discharge port 6, thereby achieving the effects of uniform stirring, stable heating and reduced residue of the material.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
