Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, and particularly relates to a dispersion stirring tank. Background Art

[0002] A stirring tank is a device used for chemical reactions in chemical laboratories, pharmaceutical industries, chemical production, etc. It is a sealed container, usually made of high-strength glass, stainless steel or other materials. The stirring tank can be used to control temperature, pressure and stirring, and is suitable for various chemical reactions and experiments. During operation, various substances are usually added into the stirring tank, and the various substances are allowed to undergo chemical reactions in the stirring tank to obtain the required reaction products. In order to make the chemical reactions of the reactants in the stirring tank more sufficient, a stirring mechanism is arranged in the stirring tank to uniformly and fully mix each reactant. However, the stirring mechanism in the existing stirring tank is relatively simple, with low stirring efficiency and the stirring effect unable to meet the needs of specific reactions. Content of the Utility Model

[0003] The purpose of the utility model is to provide a dispersion stirring tank with good stirring and heating effects.

[0004] The purpose of the utility model can be realized by the following technical solutions:

[0005] A dispersion stirring tank includes a tank body and a stirring mechanism. The interior of the tank body has a stirring chamber, with a feed inlet at the top of the stirring chamber and a discharge outlet at the bottom. The stirring mechanism is used to stir the substances in the stirring chamber, including a stirring shaft and stirring paddles arranged on the stirring shaft. A first driving motor for driving the rotation of the stirring shaft is arranged outside the top of the tank body. The stirring mechanism also includes a plurality of second driving motors installed outside the top of the tank body and respective rotating shafts driven by the corresponding second driving motors. A plurality of cutting discs are spacedly installed on each rotating shaft from top to bottom, and the cutting discs are not at the same height.

[0006] By adopting the above technical solutions, through multiple stirrings mainly with the stirring shaft and the stirring paddles arranged on the stirring shaft in the stirring chamber and supplemented by the respective rotating shafts and the plurality of cutting discs spacedly arranged on the respective rotating shafts from top to bottom, and at the same time the dividing discs can divide the substances at different heights, the stirring efficiency can be greatly improved and the stirring effect can be enhanced.

[0007] In a specific embodiment of the utility model: The cutting disc includes a disc sleeved on the rotating shaft and cutting teeth spacedly distributed on the outer circumferential surface of the disc.

[0008] In a specific embodiment of the utility model: The stirring paddle includes a one-word paddle and a stirring frame arranged from top to bottom, wherein the shape of the stirring frame can adapt to the irregular shape of the bottom of the tank body.

[0009] In the specific embodiment of the present utility model: an auxiliary support for rotatably supporting the bottom end of the stirring shaft is provided on the bottom wall of the stirring chamber.

[0010] In the specific embodiment of the present utility model: an anti-foaming paddle for eliminating bubbles is provided above the stirring paddle on the stirring shaft, and the anti-foaming paddle has serrations facing the bottom wall of the stirring chamber for piercing bubbles. With this structure, it can be avoided that in the prior art, when a chemical reaction occurs in the substances in the stirring tank, bubbles and foams will be generated. Due to the presence of foam in the tank, the release space becomes smaller, and the pressure in the tank increases, thereby affecting the utilization rate of the stirring tank equipment and the production capacity.

[0011] In the specific embodiment of the present utility model: a temperature regulating mechanism for controlling the temperature of the stirring chamber is further included. The temperature regulating mechanism is a coil pipe arranged on the outer wall of the tank body, and the coil pipe is communicated with a storage tank for storing a medium. The coil pipe has a strong temperature control ability, making the heating process more precisely controlled. At the same time, the temperature control method of the coil pipe is safer, reducing the loss and waste of resources. Moreover, by arranging the coil pipe on the outside of the tank body, the volume of the stirring chamber is larger.

[0012] In the specific embodiment of the present utility model: a cleaning mechanism for cleaning the inner wall of the stirring chamber is provided in the stirring chamber.

[0013] In the specific embodiment of the present utility model: the cleaning mechanism is a plurality of spray heads connected to a water source arranged at the upper end of the stirring shaft.

[0014] In the specific embodiment of the present utility model: a condenser for condensing high-temperature volatile substances is provided at the top of the tank body. The front inlet of the condenser is communicated with the opening at the top of the tank body, and the tail end leads the liquid substance into the stirring chamber through a return pipeline. By adopting the above technical solution, since the stirring tank may need to be heated to a relatively high temperature during the reaction process, in this case, the moisture and some liquid substances in the stirring chamber will volatilize and rise, enter the condenser through the opening at the top of the tank body, and be re-condensed into liquid substances. The liquid substances re-enter the stirring chamber through the return pipeline to react and mix, making the substances purer and reducing waste.

[0015] In the specific embodiment of the present utility model: a bent pipe section is provided at a position close to the top of the tank body on the return pipeline. With this structure, it can ensure that condensed water always exists in the bent pipe section, which can seal the outlet of the return pipeline, thereby avoiding the leakage of gas in the return pipeline to the outside.

[0016] In the specific embodiment of the present utility model: The outlet of the reflux pipeline extends into the top of the stirring chamber and is close to the inner wall of the stirring chamber. With this structure, the outlet of the yellow reflux pipeline is close to the inner wall, enabling the liquid to flow down slowly along the inner wall, alleviating the direct impact of the liquid on the stirred substance, and avoiding the liquid splashing onto areas such as the top wall that are difficult to reach and clean due to violent impact, thereby ensuring the cleanliness of the subsequent reaction process. Secondly, utilizing the preheating effect of the inner wall, when the reflux liquid flows down along the wall, the liquid can be preliminarily heated, avoiding the sudden temperature drop and local instability that may be caused by the direct impact of cold liquid on the stirred substance that is already at a relatively high temperature, and further ensuring the continuous stability of the reaction environment. Moreover, the slow spreading of the liquid along the inner wall also brings a significant dispersion effect, increasing the contact area between the liquid and the stirred substance, promoting the uniform distribution of the reflux liquid in the stirred substance, and effectively preventing the situation of excessive local concentration or uneven distribution.

[0017] In summary, in the present utility model, through multiple stirrings mainly by the stirring shaft and the stirring paddles arranged on the stirring shaft in the stirring chamber, and supplemented by each rotating shaft and multiple cutting disks arranged at intervals from top to bottom on each rotating shaft, at the same time, the dividing disks at each height can divide the substances at different heights to ensure the full mixing of each reaction substance and improve the reaction rate. Through the temperature regulating mechanism, the temperature inside the stirring tank can be controlled to promote or control the progress of the chemical reaction.

[0020] Figure 2 is a schematic structural diagram of the dividing disk of the present utility model. SPECIFIC EMBODIMENT

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0022] Please refer to Figure 1 As shown, the present utility model is a dispersion stirring tank, including a tank body 10 and a stirring mechanism 20. The tank body 10 has a stirring chamber 11 inside. An inlet is provided at the top of the stirring chamber 11, and an outlet is provided at the bottom.

[0023] Among them, the stirring mechanism 20 is used to stir the substances in the stirring chamber 11, including a stirring shaft 21 and stirring paddles arranged on the stirring shaft 21. A first driving motor 23 for driving the stirring shaft 21 is fixed to the outer side of the top of the tank body 10 through a motor bracket 22. The first driving motor 23 is connected to the stirring shaft 21 through a speed reducer 24. In this way, when the first driving motor rotates, it drives the stirring shaft 21 to rotate in the stirring chamber 11 to mix the substances. At the same time, the setting of the speed reducer 24 enables the first driving motor to have multiple speed adjustments, realizing the function of high and low speed mixing. In addition, in order to stir more fully, in this embodiment, the stirring paddles are a linear paddle 251 and a stirring frame 252 that are sleeved on the stirring shaft 21 and arranged from top to bottom. The shape of the stirring frame 252 can adapt to the irregular shape of the bottom of the tank body, thereby further improving the stirring uniformity. In addition, a plurality of scraping plates 255 are installed on the stirring frame 252. With this structure, when the stirring shaft 21 rotates, it drives the linear paddle 251 and the stirring frame 252 to rotate, and the scraping plates 255 rotate along with the stirring frame 252. The scraping plates 255 can scrape off the substances deposited or attached to the bottom of the stirring chamber, ensuring that the substances in the stirring process are fully mixed, and at the same time avoiding the accumulation of substances at the bottom, improving the stirring efficiency and uniformity.

[0024] An auxiliary support 211 for rotatably supporting the bottom end of the stirring shaft 21 is provided on the bottom wall of the stirring chamber 11.

[0025] Combined Figure 2 As shown, the stirring mechanism 20 further includes two second driving motors 27 installed on the outer side of the top of the tank body 10 and rotating shafts 28 driven by the corresponding second driving motors 27. Two cutting discs 29 are installed on each rotating shaft 28 at intervals from top to bottom. In this embodiment, each cutting disc 29 includes a disc 291 sleeved on the rotating shaft and cutting teeth 292 equally spaced on the outer circumferential surface of the disc 291, and the cutting discs 29 are not at the same height. This structure can stir and cut substances at different heights, making the mixing of each substance more uniform and the reaction more sufficient.

[0026] In this embodiment, an anti-foaming paddle 253 for eliminating bubbles is provided above the stirring paddle on the stirring shaft 21. The anti-foaming paddle 253 has sawteeth 254 facing the bottom wall of the stirring chamber for piercing bubbles. With this structure, it can avoid the situation in the prior art that when chemical reactions occur in the substances in the stirring tank, bubbles are generated, the release space in the tank becomes smaller due to the presence of bubbles, and the pressure in the tank increases, thereby affecting the utilization rate of the stirring tank and the production capacity.

[0027] In this embodiment, it further includes a temperature adjustment mechanism 30 for controlling the temperature of the stirring chamber. The temperature adjustment mechanism 30 is a coil pipe arranged on the outer wall of the tank body 10. The coil pipe is communicated with a storage tank (not shown in the figure) filled with a medium. In this way, by controlling the temperature of the medium, the medium continuously passes through the coil pipe, thereby controlling the temperature of the tank body 10. Using a coil pipe has a strong temperature control ability, and at the same time, the method of using a coil pipe to control the temperature is safer, reducing the loss and waste of resources. Moreover, by arranging the coil pipe on the outside of the tank body, the volume of the stirring chamber is larger.

[0028] In this embodiment, a condenser 31 for condensing high-temperature volatile substances is provided at the top of the tank body 10. The condenser adopts a horizontal condenser. The front-end inlet of the condenser 31 is communicated with the opening at the top of the tank body 10 through a vertical packing column 311, and the tail end leads the liquid substance into the stirring chamber 11 through a reflux pipeline 32. By adopting the above technical solution, during the reaction process, it may be necessary to heat to a relatively high temperature. In this case, the moisture and part of the liquid substances in the stirring chamber will volatilize and rise, enter the condenser through the opening at the top of the tank body, and be re-condensed into liquid substances. Subsequently, the liquid substances re-enter the stirring chamber through the reflux pipeline to continue the reaction and mixing, making the substance purity higher and reducing waste.

[0029] In this embodiment, the reflux pipeline 32 has a bent pipe section 321 near the top of the tank body. By adopting this structure, it can ensure that condensed water always exists in the bent pipe section 321, which can seal the outlet of the reflux pipeline, thereby avoiding the leakage of gas in the reflux pipeline to the outside.

[0030] In this embodiment, the outlet 322 of the reflux pipeline 32 extends into the top of the stirring chamber 11 and is close to the inner wall of the stirring chamber. By adopting this structure, when the liquid outlet of the reflux pipeline is close to the inner wall, the liquid slowly flows down along the inner wall, which can relieve the direct impact force of the liquid on the stirred substance, avoiding the liquid splashing to difficult-to-reach and clean areas such as the top wall due to violent impact, thereby ensuring the cleanliness of the subsequent reaction process. Secondly, by utilizing the preheating effect of the inner wall of the chamber, when the reflux liquid flows down along the wall, the liquid can be preliminarily heated, avoiding the possible sudden temperature drop and local instability caused by the direct impact of cold liquid on the stirred substance that has been at a relatively high temperature, and further ensuring the continuous stability of the reaction environment. Moreover, the slow spreading of the liquid along the inner wall also brings a significant dispersion effect, increasing the contact area between the liquid and the stirred substance, promoting the uniform distribution of the reflux liquid in the stirred substance, and effectively preventing the situation of excessive local concentration or uneven distribution.

[0031] A cleaning mechanism 33 for cleaning the inner wall of the stirring chamber is provided in the stirring chamber.

[0032] The cleaning mechanism 33 is a plurality of spray heads connected to a water source and arranged at the upper end of the stirring shaft.

[0033] In summary, in the present utility model, multiple stirrings are mainly carried out in the stirring cavity with the stirring shaft and the stirring paddles arranged on the stirring shaft, and supplemented by each rotating shaft and multiple cutting disks arranged at intervals from top to bottom on each rotating shaft. At the same time, the dividing disks at each height can divide substances at different heights to ensure that all reaction substances are fully mixed and the reaction rate is increased. Through the temperature regulating mechanism, the temperature inside the stirring tank can be controlled to promote or control the progress of the substance reaction.

[0034] One embodiment of the present utility model has been described in detail above, but the above content is only the preferred embodiment of the present utility model and cannot be considered as limiting the implementation scope of the present utility model. All equivalent changes and improvements made according to the application scope of the present utility model should still fall within the patent coverage scope of the present utility model.
