The existing mixing equipment is generally provided with a rotating shaft along the length direction of a tank body, a radially extending stirring blade is fixed on the rotating shaft, the stirring blade is driven to rotate in the tank body through a stirring shaft to enable production materials to be mixed, however, the traditional mixing equipment is single in stirring mode, the stirring shaft is only used for driving the stirring blade to rotate to mix, the stirring shaft is easy to cause outermost materials to form vortex-shaped rotation in the rotating process, materials in the tank uniformly rotate along the circumferential direction of the tank body, the upper part of the materials and the lower part of the materials in the tank cannot be effectively mixed, the materials are unevenly mixed, and therefore the quality of a finished product is affected, and in order to solve the technical problem, the scheme is that the following technical scheme is provided:
referring to fig. 1 to 4, a raw material mixing apparatus has a structure including: the stirring tank comprises a stirring tank body 1, a heat preservation device 2 arranged on the outer side of the stirring tank body 1, a stirring mechanism 3 is arranged in the stirring tank body 1, the stirring mechanism 3 comprises stirring shafts 31, two ends of each stirring shaft 31 penetrate through the stirring tank body 1 and are connected with the top and the bottom in a rotating mode, stirring blades 32 are distributed on two sides of the stirring shafts 31 in an staggered mode at equal intervals, one end of each stirring shaft 31 is provided with a first driving mechanism 4 for driving the stirring shafts 31 to rotate in the stirring tank body 1, the other end of each stirring shaft 31 is sleeved with a transmission rod 33 coaxially arranged with the stirring shaft 31, a first bevel gear 331 is arranged at the corresponding position of each transmission rod 33 and each stirring blade 32 in a coaxial mode, a second bevel gear 321 meshed with the first bevel gear 331 is arranged at one end of each stirring blade 32, and a second driving mechanism 5 for driving the corresponding transmission rods 33 in the stirring shafts 31 is further arranged on the outer side of the stirring tank body 1.
The first driving mechanism 4 and the second driving mechanism 5 are both composed of a motor and a speed reducing mechanism, and meanwhile, the output shafts of the first driving mechanism 4 and the second driving mechanism 5 are respectively connected with the stirring shaft 31 and the transmission rod 33, so that the stirring shaft 31 and the transmission rod 33 are respectively driven to rotate, and the transmission mode is the prior art and is not described in detail herein.
The mixing device thus has the following modes of operation when in use:
when the motors of the first driving mechanism 4 and the second driving mechanism 5 are respectively started synchronously and rotate at the same rotating speed and rotating direction, the stirring shaft 31 and the transmission rod 33 synchronously rotate in the stirring tank main body 1 and are relatively static, so that the stirring blades 32 rotate along with the stirring shaft 31, and raw materials in the stirring tank main body 1 are uniformly stirred and mixed under the action of the rotation of the stirring blades 32 around the central shaft of the stirring shaft 31;
the first driving mechanism 4 and the second driving mechanism 5 respectively drive the stirring shaft 31 and the transmission rod 33 to rotate in opposite directions or the second driving mechanism 5 stops working, and as the stirring vane 32 is provided with the second bevel gear 321 meshed with the first bevel gear 331 of the transmission rod 33, when the first driving mechanism 4 drives the stirring shaft 31 to rotate, the stirring vane 32 not only moves circumferentially around the stirring shaft 31 in the stirring tank main body 1, but also rotates around the axis of the second bevel gear 321, and the combined movement ensures that the materials in the stirring tank main body 1 are continuously subjected to the effect of up-down disturbance, ensures that the materials at the upper part and the lower part of the stirring tank main body 1 can be fully mixed, and also can prevent the outermost materials from forming a vortex effect, thereby being capable of rapidly and uniformly mixing and blending, promoting the rapid and uniform mixing of the materials and improving the quality of new products.
The first driving mechanism 4 stops working, the second driving mechanism 5 drives the transmission rod 33 to rotate in the stirring shaft 31, at the moment, the first bevel gear 331 on the transmission rod 33 drives the second bevel gear 321 to rotate together, so that the stirring blades 32 rotate on the stirring shaft 31, and as the stirring blades 32 are equidistantly and alternately distributed on two sides of the stirring shaft 31, the stirring blades 32 on two sides of the stirring shaft 31 rotate in opposite directions, the opposite rotation mode enables the raw materials in the stirring tank main body 1 to form an up-down circulation effect, the full mixing and blending of the materials at the upper part and the lower part in the tank are promoted, and the mixing is more uniform and thorough, so that the production efficiency and the fermentation quality are improved.
Through the motor work of the first actuating mechanism 4 or the second actuating mechanism 5 of independent control, impel (mixing) shaft 31 or transfer line 33 to rotate certain angle to first bevel gear 331 or second bevel gear 321 drive stirring vane 32 rotation, reach the mesh of adjusting stirring vane 32 inclination, after the inclination adjustment is accomplished, start first actuating mechanism 4 and second actuating mechanism 5 and drive (mixing) shaft 31 or transfer line 33 at the same rotational speed and rotation direction simultaneously, thereby realize adjusting stirring vane 32 inclination according to different production requirements, reach better mixing effect, and the energy saving, thereby improve production efficiency and profit.
Specifically, when different raw materials are mixed, the inclination angle used depends on the nature of the raw materials and the mixing requirement, for example, when a few powder raw materials which are difficult to dissolve are added, in order to fully dissolve and mix the powder raw materials with other liquid raw materials, a large-inclination stirring blade can be adopted, the large-inclination stirring blade can well cover the materials and bring the materials to rise and fall circularly, so that solid impurities suspended in the liquid state are fully dispersed and uniformly mixed;
in the course of reaction, the mixing effect may be affected because of the difference of liquid density caused by temperature change, so when it is necessary to keep a certain mixing state by continuous stirring, for example, in the course of heat preservation, it is recommended to use stirring blades with small inclination angle, especially for those mixtures with relatively high sugar, salt and other components or higher viscosity, the use of stirring blades with small inclination angle can form a continuous circulation in the tank, and optimize the mixing state, and at the same time avoid the production problems of excessive evaporation, weight loss reduction and the like.
In addition, when the mixing speed is low, such as adding chemicals or liquid ferment, the mixing time can be increased by adopting a small inclination angle for mixing, and the mixing effect can be improved; when rapid mixing is required, the mixing speed can be increased and the mixing time can be shortened by adopting a large inclination angle.
Therefore, the mixing equipment has various working modes, and presents periodic unsteady flow state when stirring and mixing, forms a complex flow field with materials in the tank, and can fully utilize the whole stirring area, so that the mixing is more uniform, and the mixing effect is ensured.
The stirring vane 32 includes a fixed shaft 322 rotatably connected to the side wall of the stirring shaft 31, and the second bevel gear 321 is coaxially connected to one side of the fixed shaft 322 near the first bevel gear 331, so that the fixed shaft 322 is driven to rotate on the stirring shaft 31 through the meshing transmission of the first bevel gear 331 and the second bevel gear 321 during use.
In the process of mixing production raw materials, the blade is an indispensable accessory, in long-time operation and operation, the condition that the blade damages or dirt gathers can appear, consequently, in order to conveniently maintain and repair the blade, the opposite side of fixed axle 322 is equipped with the clamp connection spare 323, right clamp connection spare 323 can dismantle and be connected with blade 324, when need wash or change blade 324, with blade 324 follow clamp connection spare 323 can, need not dismantle whole rabbling mechanism, thereby simplified maintenance operation flow greatly, it is more convenient to make wash and maintain the blade, has effectively reduced mixing apparatus's manufacturing cost and maintenance degree of difficulty.
Specifically, the clamping connection member 323 has a "U" structure, and one side of the blade 324 is inserted into the clamping connection member 323 and fixedly connected with the blade 324 by a bolt, so that when in use, one end of the blade 324 is inserted into the clamping connection member 323, and meanwhile, the clamping connection member 323 has a mounting hole aligned with the blade 324, so that the blade 324 is connected with the clamping connection member 323 by the bolt, thereby facilitating the subsequent operations of cleaning, replacement or maintenance of the blade 324;
the protruding part 325 is arranged at the plugging position of the blade 324 and the clamping connecting piece 323, and the clamping connecting piece 323 is provided with a positioning groove matched with the protruding part 325, so that when the blade 324 is installed, the protruding part 325 of the blade 324 is aligned with the positioning groove of the clamping connecting piece 323 and then inserted, the blade 324 is conveniently positioned, the installation hole of the blade 324 is aligned with the installation hole of the clamping connecting piece 323, and the installation efficiency of the blade 324 is improved; secondly, the raised parts 325 and the positioning grooves can accurately maintain the relative positions of the blade 324 and the clamping connecting piece 323, thereby effectively avoiding the phenomenon of loosening or shifting of the blade caused by vibration or load change and the like in the working process of the equipment, keeping the equipment in a long-term stable running state, and greatly reducing the failure rate and maintenance frequency of the equipment.
In order to improve the efficiency of the blade 324 in the stirring process, referring to fig. 6 to 8, two sides of the blade 324 in the length direction are respectively and alternately provided with upward and downward extending raised strips 326, so that the raw materials striking the surface of the blade can rapidly spread and splash outwards along with the rotation of the blade, the phenomenon is called a centrifugal phenomenon, and the raised strips on the two sides of the blade are staggered to promote the raw materials to be rapidly dispersed, thereby reducing the possibility of solid-phase particle aggregation; meanwhile, the streamline structure can also strengthen the permeability and the transverse penetrability of materials, so that raw materials uniformly flow around and on the blade plate, and the mixing efficiency and the mixing quality of the whole mixer are improved.
In addition, the design of the raised strips 326 can form good tearing and extrusion effects on the basis of ensuring that the resistance of the blade plate 324 is not increased for high-viscosity and easily-accumulated materials, so that the materials are easily stripped out, and the materials are completely mixed in the mixing process, so that the mixing level and uniformity are improved.
In order to improve the stirring strength and mixing efficiency of the materials, referring to fig. 7, the blade 324 is provided with a through hole, and the turbine 6 is rotatably connected in the through hole, so that the raw materials form more intense circulation and shearing action around the turbine, and the raw materials are more fully mixed together; at the same time, the turbine creates a greater turbulence intensity and intersection area in the blades 324, further improving the mixing and uniformity of the materials, especially for higher viscosity, less fluid materials, and more efficient turbine design during mixing.
Referring to fig. 9, the turbine 6 includes a rotor 61 coaxially connected to the through hole of the vane 324, a guide hole for medium circulation is provided in the rotor 61, and a plurality of guide vanes 62 are provided on the inner wall of the guide hole, so that when the raw material passes through the guide hole, stronger turbulence and hydrodynamic shear force are generated, the raw material is introduced into the dense vortex circulation, and meanwhile, the guide vanes 62 can make the material more dispersed and evenly injected into the central area of the vortex flow, and in addition, the turbine 6 can create more stirring centers when rotating in the through hole of the vane 324, so that the mixing strength and the mixing efficiency are greatly improved.
Referring to fig. 4, 8 and 9, the outer side of the rotor 61 is provided with a third bevel gear 63 coaxially connected, the fixed shaft 322 is internally provided with a gear transmission member 64 coaxially arranged, one end of the gear transmission member 64 is meshed with the third bevel gear 63, and the transmission rod 33 is provided with a fourth bevel gear 332 meshed with the other end of the gear transmission member 64, so that when the first bevel gear 331 is meshed with the second bevel gear 321 for transmission, the fourth bevel gear 332 drives the third bevel gear 63 to rotate in the through hole of the blade 324 through the gear transmission member 64, thereby driving the rotor 61 to synchronously rotate in the through hole of the blade 324, generating vortex under the action of the guide vane 62, causing the blade 324 to pass through the guide hole and generate vortex in the stirring process, causing shearing action between materials and causing the materials to be mixed more uniformly.
Referring to fig. 8 and 9, the blades 324 are respectively provided with two sets of through holes and turbines 6, and the outer sides of the two turbines 6 are respectively provided with a ring gear 65, the ring gears 65 on the two turbines 6 are meshed with each other, and in particular, the ring gears 65 are coaxially arranged with the rotors 61, so that after the gear transmission member 64 drives one of the turbines 6 to rotate through the third bevel gear 63, the ring gears 65 of the two sets of turbines 6 are meshed with each other, and further, the two rotors 61 are driven to rotate in opposite directions, and when the material passes through the diversion holes of the two turbines 6, two sets of eddy currents with opposite directions are formed and collide with each other, so that intense turbulence is generated, and the mixing is more thorough.
The diameter of the diversion hole of the turbine 6 is gradually enlarged from the middle to the upper end and the lower end respectively, when raw materials pass through the diversion hole, the speed of the raw materials can be gradually accelerated along with the expansion of the inner diameter of the diversion hole, so that acceleration and centrifugal force to a certain extent act between the material particles, and the materials are more fully mixed together.
The rotor 61 is connected with the blade 324 through the through hole to form an axial transmission path of the rotation motion, which is helpful for transmitting stirring force and shearing force to liquid or solid materials, in order to prevent the materials from influencing the normal rotation of the rotor due to entering the gap between the through hole and the rotor 61, as shown in fig. 5 and 7, annular sealing strips 327 are respectively arranged at the upper end and the lower end of the through hole of the blade 324, so as to seal the gap between the rotor 61 and the through hole of the blade 324.
Referring to fig. 10, two stirring blades 32 adjacent to each other from top to bottom on the same side of the stirring shaft 31 may be disposed vertically, so that when the material is guided by the turbine 6 of the lower horizontal blade 324 to flow from the flow guiding hole, the direction of the formed vortex flow will change after passing through the lower horizontal blade 324, so that a stronger collision and shearing effect is formed between the materials, and the mixing of the liquid and the solid material is promoted, so that the mixing is more uniform and finer.
