Description

Technical Field

[0001] The present invention belongs to the technical field of mixing between liquids or between liquids and powders, and particularly relates to a circulating pressure - type liquid preparation tank. Background Art

[0002] The mixing quality and mixing speed are important factors for measuring a preparation tank, and the setting method and operation form of the stirring part are directly related to the mixing quality and mixing speed. When mixing and preparing trace raw materials, such as preparing nutrient solution with trace elements, since the proportion of trace raw materials is relatively small, even a small deviation in quality during the weighing and adding process, as well as during the stirring and mixing process, will cause a large change in the content of trace elements, which has a crucial impact on the mixing quality. In addition, when mixing and stirring two or more substances that are not easily compatible, even with the addition of an emulsifier, a layering phenomenon will still occur, reducing the mixing quality and mixing speed.

[0003] Chinese patent document with publication number CN210752216U discloses a liquid preparation tank for aquaculture, including a tank body, a tank cover, an inner tank and an openable tank cover. The top of the tank body is welded with a tank cover, and one side of the tank cover is connected with an openable tank cover through a rotating shaft. A lead screw is fixed on the top of the tank cover through bolts, and a lifting platform is arranged between the lead screws. A spring is sleeved outside the lead screw, and a fixing nut is sleeved on the top of the spring. A stirring motor is fixed on the top of the lifting platform through bolts, and the bottom output end of the stirring motor is connected with a transmission rod through a connecting sleeve. By setting the lead screw, the spring and the fixing nut, the fixing nut can be rotated to move the lifting platform downward, so that the stirring motor, the transmission rod and the stirring fan blades move downward. At the same time, a spoiler is welded inside the inner tank, which can reduce the probability of the liquid generating vortices during stirring, and is suitable for being widely promoted and used.

[0004] The commonly used rotating stirring - type mixing method is likely to generate vortices, that is, swirling phenomena, during the liquid stirring process, resulting in reduced or ineffective stirring effects. When further using the stirring method of alternating forward and reverse rotations, although the generation of vortices can be reduced, frequently changing the direction will interrupt the continuity of stirring, resulting in energy loss and reduced overall efficiency. Moreover, the direction switching will also cause unstable liquid flow, resulting in local uneven mixing and affecting the uniformity. This phenomenon is particularly obvious in liquids with viscosity. Therefore, the stirring method of alternating forward and reverse rotations has a relatively limited application range. Summary of the Invention

[0005] In order to overcome the technical problems in the prior art that the rotary stirring method will cause swirling and uneven stirring, resulting in poor preparation effect and long preparation cycle. An object of the present invention is to provide a circulating pressure - type liquid preparation tank, in which the outer ring that reciprocates longitudinally in the tank body drives the liquid to move in a circular motion for mixing. At the same time, when the outer ring moves upward, it can also lift the liquid at the bottom of the tank body for mixing, preventing stratification and uneven mixing. In addition, the circumferential rotation and longitudinal sliding of the outer ring can also scrape the inner wall and bottom of the tank body to prevent the adhesion of raw materials such as powders, further improving the mixing quality and mixing rate.

[0006] To achieve the above object, the present invention is implemented by the following technical solutions: A circulating pressure - type liquid preparation tank includes a tank body, and an opening is provided at the upper end of the tank body; an outer ring, which is longitudinally slidably connected in the tank body, and the outer wall of the outer ring abuts against the inner wall of the tank body; an inner tube, which is coaxially arranged in the middle of the outer ring; a plurality of flow - deflecting plates, which are evenly distributed along the circumferential direction, and the flow - deflecting plates are obliquely arranged between the outer wall of the inner tube and the inner wall of the outer ring; a plurality of sector plates, which are evenly distributed along the circumferential direction, and the sector plates are rotatably connected to the inner bottom of the inner tube, and the sector plates can selectively close the bottom of the inner tube; wherein, when the sector plates rotate to be inclined, the inclination direction is opposite to that of the flow - deflecting plates; a driving ring is longitudinally slidably connected in the tank body, and the driving ring can selectively drive the outer ring to longitudinally slide or circumferentially rotate.

[0007] When the outer ring slides downward, the sector plates rotate upward under the resistance of water, opening the inner tube. The sector plates and the flow - disturbing plates drive the water flow in opposite directions, forming a turbulent flow, which helps to increase the stirring and mixing effect; when the outer ring slides upward, the sector plates rotate downward to close the lower opening of the lower end of the inner tube, and the inner tube lifts the lower - layer liquid, increasing the mixing effect, aiming at the mixing speed between two kinds of liquids that are not easily compatible or between powders and liquids.

[0008] Furthermore, the driving ring is longitudinally slidably connected in the inner tube; a circulating groove is arranged along the circumferential direction on the inner wall of the inner tube; the circulating groove includes a plurality of linearly arranged grooves that are inclined and connected end to end in sequence, and the inclination directions of two adjacent linearly arranged grooves are opposite; at least one elastic column is arranged on the driving ring; the elastic column is slidably connected in the circulating groove.

[0009] Specifically, a spring is arranged between the elastic column and the driving ring, and the elastic force of the spring is used to make the elastic column slide towards the inner bottom of the circulating groove; inclined blocks are respectively arranged in each of the linearly arranged grooves;

[0010] The thin end of the inclined block is close to the thick end of another adjacent inclined block; the inclined blocks enable the elastic column to slide only in one direction along the circulating groove.

[0011] When the outer ring slides downward until it abuts against the inner bottom of the tank body, the driving ring slides longitudinally, which will cause the elastic column to drive the outer ring to rotate. The outer ring scrapes the inner bottom of the tank body to prevent raw materials such as powder from adhering. Similarly, when the driving ring starts to slide upward, it drives the outer ring to rotate.

[0012] Furthermore, a plug board is horizontally and slidably connected inside the driving ring, and the plug board can be selectively inserted into the inner tube; a connecting rod assembly is arranged between the top of the tank body and the driving ring; the connecting rod assembly is in transmission connection with the plug board.

[0013] Specifically, when the driving ring slides to the inner bottom of the inner tube, the driving ring abuts against the sector plate to close the inner tube; a plurality of diversion holes are arranged on the inner wall of the inner tube along the circumferential direction.

[0014] When the outer ring slides upward, the liquid in the inner tube flows out around the diversion holes, and at the same time, the liquid above the inner tube is continuously replenished. In this way, the cycle is repeated, avoiding the occurrence of layering phenomenon, reducing the dosage of emulsifier, and accelerating the preparation rate.

[0015] Specifically, an annular groove is arranged on the upper part of the inner tube along the circumferential direction; the plug board is rotatably connected in the annular groove.

[0016] Specifically, the connecting rod assembly includes at least one connecting rod group; the connecting rod group includes two connecting rods whose ends are rotatably connected to each other. One end of one of the connecting rods is rotatably connected to the top of the tank body, and the other end of the other connecting rod is rotatably connected to the driving ring; the connecting rod located below is in transmission connection with the plug board.

[0017] Furthermore, a driving column is arranged at the lower end of the connecting rod located below; a driven column is arranged at the upper end of the plug board; a combined sliding groove for sliding connection with the driven column is arranged on the outer wall of the driving column; the combined sliding groove includes an inclined groove arranged obliquely and a circumferential groove arranged along the circumferential direction; one end of the circumferential groove is communicated with one end of the inclined groove.

[0018] While the connecting rod drives the outer ring to slide longitudinally, it can also drive the plug board to slide, simplifying the motion mechanism.

[0019] Specifically, a support arm is arranged at the upper end of the connecting rod located above; a hydraulic cylinder is arranged between the end of the support arm and the tank body.

[0020] Specifically, a mounting frame is arranged near the upper part inside the tank body; the connecting rod located above is rotatably connected to the mounting frame.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. The present invention presses and stirs and mixes between liquids or between a liquid and a powder through a reciprocatingly longitudinally sliding outer ring, which can avoid the generation of swirling phenomena, has uniform stirring and a fast mixing speed, and can be compatible with liquids having a relatively high viscosity and two liquids that are not easily compatible.

[0023] 2. When the outer ring slides downward, it drives the fluid to rotate in two directions respectively to form a turbulent flow, improving the stirring and mixing quality and uniformity. When the outer ring slides upward, it lifts the liquid at the bottom layer upward, preventing stratification, reducing the dosage of emulsifier, and improving the mixing uniformity and mixing speed.

[0024] 3. During the longitudinal sliding process of the outer ring, it can scrape the inner wall of the tank body. When the outer ring slides to the inner bottom, it can also scrape the inner bottom of the tank body, preventing powder or raw materials with strong adsorption from adhering to the inner wall of the tank body, and improving the mixing quality and uniformity.

[0025] 4. The stirring structure of the present invention is concise and concentrated, and is integrally enclosed in the tank body, which can not only avoid the outward splashing of the liquid, but also form a sealed environment in the tank body, and is applied to raw material liquids with relatively high requirements.

[0043] A circulation groove 213 is arranged along the circumferential direction on the inner wall of the inner tube 211; the circulation groove 213 includes a plurality of linearly arranged inclined grooves connected end to end in sequence, and the inclination directions of two adjacent linearly arranged inclined grooves are opposite; four elastic columns 33 evenly distributed along the circumferential direction and slidably connected to the driving ring 31 are arranged on the driving ring 31; a spring 34 is arranged between the elastic column 33 and the driving ring 31; the elastic force of the spring 34 is used to make the elastic column 33 slide towards the bottom inside the circulation groove 213; an inclined block 214 is arranged in each linearly arranged inclined groove; the thin end of the inclined block 214 is close to the thick end of another adjacent inclined block 214; the inclined block 214 enables the elastic column 33 to only slide unidirectionally along the circulation groove 213.
