Description

Technical Field

[0001] The utility model relates to a device for stirring a solid-liquid mixture. Background Art

[0002] In the processing and production of water-based emulsions, efficient and refined stirring and mixing technology is one of the key links to ensure product quality and production efficiency. The Chinese patent with patent publication number CN107790045A discloses a liquid paint agitator, including a mixing barrel, a slide rail, a slider, a cross frame, a bracket, a shock-absorbing spring, a vibration module, a feed port, a discharge port, a rotating motor, a rotating shaft, a stirrer, a No. 1 plate, a No. 2 plate, an elastic rope, a connecting rod and a cleaning module; a slide rail and a slider are provided on the outer wall of the mixing barrel, and a bracket is provided on the upper part. The vibration module drives the cam and the cross frame as well as the mixing barrel to move up and down to achieve full mixing of the paint. The agitator in the mixing barrel can fully mix and stir the paint, and the cleaning module can clean the inner wall of the mixing barrel after the stirring process is completed.

[0003] Traditional stirring systems, especially the design of the main agitator, are often difficult to fully adapt to the processing requirements of high-viscosity and high-solid content materials in modern production processes. For example, the original main agitator usually adopts a single disc design with a relatively simple structure, which easily leads to problems such as uneven stirring, low separation efficiency and liquid splashing when processing specific water-based emulsions, which not only affects the safety of the working environment, but also limits the improvement of production efficiency and product quality.

[0004] At the same time, the design of the mixing barrel, as the core equipment for carrying and completing the dispersion and mixing of water-based materials, is also crucial. Although the early mixing barrel design has certain practicality, it has shown limitations in the face of large-scale production needs, changes in material properties, and the convenience of subsequent cleaning and maintenance. In particular, the lack of effective splash prevention measures and incomplete emptying design may lead to waste of raw materials and difficulty in cleaning, increasing production costs.

[0005] In view of the above technical bottlenecks, the market urgently needs a mixing system improvement solution that can significantly improve mixing efficiency, reduce material splashing, and optimize cleaning and cost-effectiveness.

Utility Model Content

[0007] The utility model aims to provide a liquid material stirring device to achieve higher stirring efficiency.

[0009] This device is designed for stirring aqueous emulsions with specific viscosity and solid content, especially when used in the production process of plugging agents, the relevant beneficial effects are very prominent. Through innovative design, the technicians added a second layer of stirring structure to the main agitator, achieving better stirring and separation efficiency, and the phenomenon of liquid splashing is no longer prone to occur during the stirring process. The structure of the stirring barrel has been improved. The barrel cover can be closed during the working process, and the stirring shaft can stir the material in the barrel through the stirring hole without being hindered by the barrel cover.

[0019] The utility model is further described in detail below through specific implementation methods:

[0020] The reference numerals in the drawings of the specification include: a frame 1, a roller 11, a barrel cover 12, a barrel body 2, a valve 21, a mixer 3, a mixing shaft 31, an upper blade 32, and a lower blade 33.

[0021] The embodiment is basically as shown in the attached Figure 1 , 2 As shown:

[0022] The present embodiment provides a liquid material stirring device, including a barrel body and a mixer fixed on a frame. The barrel body is a standardized ton barrel and can be placed on the bottom plate of the frame. The mixer is fixed on the top of the machine by a column, and is connected to a double-layer stirring blade by a vertically retractable stirring rod. The stirring blades are divided into two layers, an upper blade and a lower blade. The upper layer is three inclined paddle blades, each with a diameter of about 26 cm, which are designed to be inclined at a certain angle to enhance the upper and lower circulation mixing of the material; the lower layer adopts six curved blade disc turbine blades, which are designed to achieve uniform lateral and longitudinal dispersion of the material through the strong vortex generated by the turbine blades. The vertical spacing between the two layers of stirring blades is carefully set to 16 cm. This spacing optimizes the flow path of the liquid material and ensures efficient mixing and dispersion during the stirring process.

[0023] The barrel is designed as a square structure with moderate size, which not only improves the space utilization, but also facilitates installation and maintenance. The barrel wall thickness is about 5cm, and it is made of high-quality stainless steel to ensure the durability and corrosion resistance of the stirring device. In addition, in order to facilitate movement and positioning, sturdy rollers are installed at the bottom of the barrel, making it possible to flexibly mobilize the equipment within the workshop.

[0024] There is an openable lid on the top of the barrel, which is connected to the frame by a hinge, so that the operator can open it to fill or inspect the material. There is a strip-shaped stirring hole on the upper edge of the lid, which is large enough to pass the stirring shaft, ensuring that the stirring shaft can operate smoothly even when the lid is closed, effectively avoiding the overflow of liquid during stirring. There is a valve at the bottom of the barrel, which is scientifically and reasonably designed. After the operation is completed, the residual material in the barrel can be quickly and thoroughly discharged, which greatly simplifies the cleaning process and reduces the subsequent processing costs.

[0025] The above is only an embodiment of the present invention. For those skilled in the art, several modifications and improvements may be made without departing from the present invention, for example:

[0026] Develop a stirring blade that can automatically adjust the angle or shape according to the material characteristics. Shape memory alloy paddle blades can be made so that the blades automatically deform to achieve a smaller inclination when the temperature is higher. Since the higher the temperature, the better the fluidity of the material, the smaller blade inclination at high temperature can achieve good stirring and separation efficiency and reduce energy consumption while ensuring good stirring performance.

[0027] Another improvement scheme: an annular blade seat is fixed on the stirring shaft, and stirring blades are arranged on the blade seat. An inwardly concave additive silo is provided on the outer surface of the blade seat, and a cover plate is hinged on the outer surface of the additive silo on the blade seat through a torsion spring. The torsion spring makes the cover plate cover the additive silo under normal conditions, thereby preventing the additive inside the additive silo from accidentally leaking out. During the working process, the stirring shaft drives the blade seat to rotate in the material. When the speed changes, the pressure on the outer surface of the cover plate will change. This pressure comes from the inertia of the cover plate itself and the change in the speed of the external fluid (Bernoulli principle). When the pressure exceeds the threshold of the torsion spring, the cover plate will open, thereby releasing the internal additive. This scheme allows the equipment to automatically release the additive after the speed reaches a certain level, and can be used to add additives that need to be added under specific conditions.

[0028] These improvements should also be considered as the scope of protection of the utility model, and they will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
