The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

As described in the background of the application, at present, stirring equipment utilizes the mode of mechanical stirring to stir the material more, sets up the pivot that has the paddle usually inside stirring equipment, the pivot is connected with the outside motor of stirring equipment, and the pivot rotates and drives the paddle rotation under the drive of motor to the realization is to the stirring of material. However, the mechanical stirring mode often has a better stirring effect on the area involved by the blade, and the stirring of the materials in the corner area inside the stirring equipment is not obvious, so that the materials in the stirring equipment are not sufficiently mixed, and the stirring effect is not ideal.

In view of the above, the embodiment of the present application provides a stirring apparatus 10, which is used for solving the technical problem that the stirring effect is not ideal due to insufficient mixing of materials in the current stirring manner. As shown in fig. 1, the stirring device 10 comprises a stirring vessel 101 provided with a liquid inlet pipe 102, a flow distribution pipe 103 and a fluid power conveying device 104; wherein the flow distribution pipe 103 is provided in the agitation vessel 101; the fluid power transmission device 104 is arranged outside the stirring container 101 and is connected with one end of the flow distribution pipe 103.

The liquid inlet pipe 102 may be used to introduce a material into the stirring container 101, where the material may be a gas, a liquid, and a solid, or a mixture of at least two of them, and the material is preferably a liquid.

The stirring container 101 is a container for containing materials to be stirred, and provides a space for stirring the materials. The stirring container 101 may be made of carbon steel anticorrosive material, glass fiber reinforced plastic material, or polypropylene material, and the material may be selected according to the property of the contained material. The shape of the stirring container 101 may be a cylinder, and when the material in the stirring container 101 is stirred, the cylindrical stirring container may reduce a stirring dead angle. Of course, the specific shape of the stirring container 101 can be set according to actual needs.

The flow distribution pipe 103 is used for introducing fluid into the liquid in the stirring container 101 to generate disturbance on the liquid. The flow distribution pipe 103 may be used for stirring only, or may be used for adding other materials to be mixed with the materials in the stirring container 101. For example, the materials to be mixed include two materials, namely liquid a and liquid B, and the liquid a may be introduced into the stirring container 101 from the liquid inlet pipe 102, and then the liquid B is introduced into the liquid a in the stirring container 101 through the flow distribution pipe 103 to disturb the liquid a; the flow distribution pipe 103 simultaneously performs the functions of adding the material liquid B and stirring the liquid a and the liquid B. In practical applications, the materials to be mixed may also include more materials, for example, the materials include liquid a, liquid B and liquid C, and then the liquid a may be introduced into the stirring container 101 from the liquid inlet pipe 102, and then the liquid B and the liquid C are introduced into the liquid a in the stirring container through the flow distribution pipe 101, so as to disturb the liquid a, thereby achieving mixing and stirring of the liquid a, the liquid B and the liquid C. The liquid B and the liquid C may be introduced into the liquid a through the flow distribution pipe 103, the liquid B and the liquid C may be introduced into the liquid a sequentially and separately, or a mixture of the liquid B and the liquid C may be introduced into the liquid a. In addition, there are various ways of mixing the liquid a, the liquid B and the liquid C in the stirring vessel 102, for example, the liquid a and the liquid B are introduced first, and the liquid C is introduced through the flow distribution pipe 103; alternatively, the liquid a, the liquid B, and the liquid C are introduced first, and the other fluid is introduced through the flow distribution pipe 103. The arrangement position of the flow distribution pipe 103 in the stirring container 101 can also be set according to actual needs, for example, the flow distribution pipe 103 can be arranged at the bottom of the stirring container 101, or can be arranged at the middle part of the stirring container 101.

The fluid power transmission device 104 is used for transmitting fluid into the flow distribution pipe 103 at a certain pressure, and it is understood that the fluid power transmission device 104 includes a power device, and can transmit fluid into the pipe of the flow distribution pipe 103 at a certain pressure, so that the fluid coming out of the flow distribution pipe 103 forms a jet state, and can generate disturbance to the liquid in the stirring container 101, so as to realize stirring. The fluid delivered by the fluid power delivery device 104 to the flow distribution pipe 103 may be a liquid, a gas, or a mixture of a liquid and a gas. The power means may be a delivery pump.

By last knowing, agitated vessel equipment 10 that this application embodiment provided, when needs stir, the material is followed inlet pipe 102 gets into stirred vessel 101, and fluid power delivery device 104 is with certain pressure with fluid transport income distributing pipe 103, during the fluid forms the material that the efflux was squeezed into in stirred vessel 101 via distributing pipe 103, it is right the material forms the disturbance, causes the flow of material in stirred vessel 101, and it is right to realize the stirring of material, each composition mixes more evenly in enabling the material, and then improves stirring effect.

In order to further increase the pressure of the fluid flowing out of the flow distribution pipe 103, the disturbance intensity of the material in the stirring container 101 is enhanced, and the stirring effect is further improved. In one embodiment, the wall of the flow distribution pipe 103 is provided with a gap 1031, and the gap 1031 is arranged along the length direction of the pipe, as shown in fig. 2.

The width of the gap 1031 may be set according to actual needs. The number of the gaps 1031 and the orientation in the agitation vessel 101 may be set according to the arrangement position of the flow distribution pipe 103 in the agitation vessel 101. For example, when the flow distribution pipe 103 is provided at the bottom of the stirring vessel 101, only one gap may be provided in the flow distribution pipe 103, the gap extending from one end of the flow distribution pipe 103 to the other end of the flow distribution pipe, and the gap may face the top of the stirring vessel 101; under the condition that the flow distribution pipe is arranged in the middle of the stirring container 101, two gaps penetrating from one end of the flow distribution pipe 103 to the other end of the flow distribution pipe can be arranged on the flow distribution pipe 103, the two gaps are positioned on the opposite sides of the flow distribution pipe 103, the direction of one gap is opposite to the top of the stirring container 101, and the direction of the other gap is opposite to the bottom of the stirring container 101, so that jet flow can be generated and simultaneously driven into materials above the flow distribution pipe 103 and materials below the flow distribution pipe 103, the materials above the flow distribution pipe 103 and the materials below the flow distribution pipe 103 can be simultaneously stirred, and the stirring efficiency is improved.

In one embodiment, the gap 1031 is flared in cross-section, as shown in fig. 3.

The interface of the gap 1031 is arranged to be horn-shaped, so that the jet flow column can be helped to maintain high pressure to be driven into the material. If the gap 1031 is configured as a conventional straight line, the jet stream column coming out of the gap 1031 can only maintain a high pressure of a short path, and the pressure of the jet stream column at a position farther from the gap 1031 may be small, so that the stirring effect on the material farther from the gap 1031 is not ideal. The gap 1031 is flared, the section of the fluid ejected from the flow distribution pipe 103 is narrowed and widened again, and the path of the flared section provides an acceleration runway for the fluid ejection, so that the ejection pressure of the jet flow column can be further increased, the jet flow column can maintain the high pressure of a long path in the material in the stirring container 101, and the stirring effect is improved.

However, the flared section is formed on the wall of the flow distribution pipe 103, and the "acceleration track" provided by the flared section is limited by the wall thickness of the flow distribution pipe 103. Thus, in one embodiment, a sheet of material is rolled into the flow tube 103 with a gap between the first and second ends 1032, 1033, and the second end 1033 overlaps the first end 1032 a predetermined length to form the trumpet-shaped gap 1031.

As shown in fig. 4 (a cross-sectional view of the flow distribution pipe 103), the second end 1033 overlaps the first end 1032 for a predetermined length to form the trumpet-shaped gap 1031, and the trumpet-shaped gap 1031 corresponding to the overlapped predetermined length forms an "acceleration runway". On the other hand, the pipe section of the flow distribution pipe 103 is configured as shown in fig. 4, so that a fluid "squeezing out" effect can be formed at the gap 1031 on the pipe wall of the flow distribution pipe 103 based on the coanda (Conada) effect, the fluid is squeezed out into the stirring container through the gap 1031 after entering the flow distribution pipe 103, the process is that the section through which the fluid passes is narrowed and widened again, the moving direction of the fluid in the flow distribution pipe 103 in the curved pipe wall corresponding to the gap 1031 is along the curve of the curved inner wall under the action of the venturi principle, and the flow velocity is rapidly increased, as shown by the arrow in fig. 4, and then a jet with larger pressure is formed through the gap 1031, and when the direction of the gap 1031 is opposite to the top of the stirring container 101, an upward vertical jet is formed. The pipe diameter of the flow distribution pipe 103 may be 6cm, and the width of the gap 1031 may be 0.5 cm.

The arrangement of the flow distribution pipe 103 in the stirring vessel 101 may be set according to actual conditions, for example, the flow distribution pipe 103 may be a straight line type, a net type, a divergent type, or the like. In a preferred mode, the flow distribution pipe 103 is disposed at the bottom of the stirring vessel 101 in an archimedean spiral shape, as shown in fig. 5.

In the embodiment, the distribution pipe 103 is in the shape of an archimedean spiral, when fluid is injected into the material in the stirring container 101, a spiral annular flow state with a high flow speed is formed above the distribution pipe 103 in the shape of the archimedean spiral, and due to the upward movement of the fluid from the distribution pipe 103, the pressure in the middle area of the spiral annular flow state is reduced, so that the material in the middle area of the spiral annular flow state also forms a vertical upward flow state with a relatively low flow speed. That is, the flow distribution pipe 103 is set to be in the shape of an archimedean spiral, which can drive the material in the middle area of the spiral annular flow state to move, thereby improving the stirring effect. The diameter of the outermost circle of the flow distribution pipe 103 can be 1/3-1/2 of the diameter of the stirring container 101, and the flow distribution pipe 103 can be arranged for 2-3 circles.

On this basis, in order to further improve the stirring effect, in an embodiment, the stirring device 10 further includes a flow guide baffle 105, and the flow guide baffle 105 is disposed inside the stirring container 101 and above the corresponding inlet of the liquid inlet pipe 102 on the stirring container 101, as shown in fig. 5.

Through setting up drainage baffle 105 on stirred vessel 101 upper portion, flow to upper drainage baffle 105 together when the regional relatively slower flow state of velocity of flow in the middle of spiral annular quick flow state and spiral annular flow state, under drainage baffle 105's effect, the regional relatively slower flow state of velocity of flow all changes the direction in the middle of spiral annular quick flow state and spiral annular flow state, form to flow state all around and below, form the circulation flow state jointly with the regional relatively slower upward flow state of velocity of flow in the middle of spiral annular quick and spiral annular flow state, as shown by the arrow in fig. 5, thereby realize stirred vessel 101 interior material intensive mixing, the stirring effect is improved. On the other hand, the flow regime that the regional velocity of flow is relatively slow in the middle of the spiral annular flow regime can also eliminate the downward misorientation fluid that regional fluid flow direction drainage baffle produced in the middle of the spiral annular flow regime for the material forms regular cyclic motion state in stirred vessel 101, upwards flows to the drainage baffle from stirred vessel 101 middle part, then changes the flow direction, flows downwards at stirred vessel 101's periphery, thereby realizes the intensive mixing of material in stirred vessel 101.
