Description

Technical Field

[0001] The invention relates to the technical field of feed premix powder preparation, in particular to a premix powder mixing device with a powder block crushing function. Background Art

[0002] Premix, short for additive premix feed, is an intermediate compound feed product made by uniformly mixing one or more trace components (including various trace mineral elements, vitamins, synthetic amino acids, certain medications, and other additives) with a diluent or carrier in the required proportions. Premix is ​​a key component of complete compound feed.

[0003] In the existing stirring and mixing equipment, the materials are simply poured into the mixing equipment hopper and then stirred by the blades. The material migration is irregular and has a small range. The crushing of some agglomerated materials is not very targeted. The mixed premixed powder still has a lot of agglomerates, and the quality of the premixed powder cannot be further improved. In order to reduce the agglomeration, a long period of stirring is generally required, which wastes time and energy. It is also a waste of time to continue to stir the materials that have been fully mixed. Summary of the Invention

[0004] The object of the present invention is to provide a ready-mixed powder mixing device with a powder block crushing function to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A premixed powder mixing device with a powder block crushing function, the mixing device includes a shell, a main power drive, a rotor assembly, a feed port, a discharge plate, a flip drive, and an auxiliary stirring assembly. The shell side wall extends out of a support to install the main power drive, the rotor assembly is rotatably installed on the shell side wall, the rotor assembly penetrates into and out of the shell, the end of the rotor assembly is connected to the main power drive transmission, the feed port is set at the top of the shell, the discharge plate is installed at the bottom of the shell, the discharge plate can be flipped at the bottom of the shell to open or close the shell cavity, the flip drive is installed on the bottom side wall of the shell, the flip drive is connected to the discharge plate transmission, the auxiliary stirring assembly is installed on the discharge plate, and the auxiliary stirring assembly is provided with a rotating structure facing the shell cavity.

[0007] The material is added into the inner cavity of the shell from the feed port. At this time, the discharge plate remains horizontal, and a relatively closed chamber is formed in the shell. The rotor assembly performs the main stirring action of the material in the shell, carrying the material to migrate over a large range, collide with each other, etc., so that the agglomerated material is broken and the various original materials are fully mixed. The auxiliary stirring assembly crushes and shears some material blocks retained at the bottom of the chamber, because the probability of agglomerated materials appearing here is greater. For local positions such as corners where the rotor assembly is not easy to touch the pole, the auxiliary stirring assembly performs stirring and mixing operations, and cooperates with the rotor assembly to perform a complete premixed powder mixing operation. After the material stirring and mixing is completed, the discharge plate is driven to flip, the bottom of the shell is opened, and the material falls downward for bagging or transportation to other subsequent processing steps.

[0008] The rotor assembly includes a main shaft, a first main blade, and a second main blade. The main shaft is rotatably mounted in a bearing seat on the outer surface of the shell. The main shaft is connected to the main power drive transmission. The first main blade and the second main blade are rotatably mounted on the main shaft. The first main blade and the second main blade are spiral blades with opposite rotation directions. The direction of the first main blade and the second main blade is adjustable.

[0009] There are two main blades rotating on the main shaft with different rotation directions. If they rotate in the same direction, then they can push the material in the shell to the middle or to the sides under different rotation directions of the main shaft. If they rotate in different directions, then the material will be pushed toward one end. Constantly changing the rotation direction can allow the material to migrate in the shell and increase the mixing effect.

[0010] The rotor assembly also includes a steering exchange gear set arranged at the end of the main shaft. The steering exchange gear set serves as an intermediate piece to establish transmission between the first main blade, the second main blade and the main shaft respectively. The steering exchange gear set can switch the transmission direction from the main shaft to the first main blade and the second main blade.

[0011] The gear set can use external-external gear meshing and internal-external gear meshing to establish different directional transmissions. When switching the direction of the two main blades, just turn the gear set separately. Although the torque on the main shaft is large and the speed is low, it is still recommended to switch the direction of the two main blades only when the main shaft stops.

[0012] The auxiliary stirring assembly includes an auxiliary motor, a power transmission shaft, an auxiliary stirring wheel, and a speed matching assembly. The auxiliary motor is installed on the lower surface of the discharge plate, and the power transmission shaft is rotatably installed under the discharge plate. The axis of the power transmission shaft is in the horizontal direction. The power transmission shaft is connected to the auxiliary motor by transmission. There are several auxiliary stirring wheels and speed matching assemblies of the same number. The auxiliary stirring wheel passes through the discharge plate and is rotatably connected to the discharge plate. The auxiliary stirring wheel establishes transmission with the power transmission shaft through the speed matching assembly.

[0013] The speed matching component transmits different speeds according to the torque uniformity during the rotation of the auxiliary stirring wheel. When the torque fluctuation of the auxiliary stirring wheel is large, the speed transmitted from the power transmission shaft to the auxiliary stirring wheel is increased.

[0014] Several auxiliary stirring wheels rotate under the main blades, fully crushing and mixing some agglomerated materials retained here. The auxiliary stirring wheels can reflect whether there are agglomerates in the area they cover through torque fluctuations. If the material is completely uniform, then the torque on the auxiliary stirring wheel here is also uniform, and it only needs to move at a lower speed. If there are some agglomerated materials, there will inevitably be collisions during the contact process between the auxiliary stirring wheel and the material, and the torque will also fluctuate. Therefore, the auxiliary stirring wheel in contact with the agglomerated material takes greater power from the force transmission shaft to perform crushing operations, thereby realizing power distribution within the auxiliary stirring assembly.

[0015] The auxiliary stirring wheel includes a wheel disc, a distribution shaft, a piston, a return spring, and a relay gear. Blades are arranged on the upper part of the wheel disc, and the lower part of the wheel disc is a rotating body rotatably mounted on the discharge plate. The lower end of the wheel disc is axially engaged with the distribution shaft and limited, and the wheel disc and the distribution shaft are relatively rotatable. A transmission oil chamber is provided at the lower part of the wheel disc, and an oil hole connecting the outer surface and the center is radially provided at the head portion where the distribution shaft is connected to the wheel disc. A piston oil chamber is provided at one end of the distribution shaft away from the wheel disc, and the oil hole connects the transmission oil chamber and the piston oil chamber. The piston is slidingly arranged in the piston oil chamber, and the end of the piston away from the wheel disc extends out of the distribution shaft. A return spring is arranged between the end face of the piston and the bottom surface of the piston oil chamber. When the wheel disc and the distribution shaft rotate relative to each other, the volume of the transmission oil chamber decreases, and the relay gear is fixed to the outer surface of the distribution shaft.

[0016] A constant speed gear is set at the position of each speed matching component on the power transmission shaft. The speed matching component includes a revolving frame, a revolving gear, a resistance sleeve, a pressure ring, and a speed change gear. The revolving frame is rotatably installed on the power transmission shaft. Several revolving gears are set to rotate radially at the end of the revolving frame. The resistance sleeve is pressed at the end of the revolving frame by the pressure ring. The resistance sleeve covers the rotating shaft part of the revolving gear. The resistance sleeve is an elastic member. The pressure ring floats radially along the end of the revolving frame. The outer surface of the pressure ring is slidably pressed against the end of the piston. The speed change gear is rotatably installed on the power transmission shaft. The speed change gear has a first tooth surface and a second tooth surface. The first tooth surface and the second tooth surface both rotate with the power transmission shaft as the axis. The revolving gear is respectively meshed with the first tooth surface and the constant speed gear, and the second tooth surface is meshed with the relay gear.

[0017] The auxiliary agitator wheel senses the material agglomeration situation in its local area through the two-section shaft. If the resistance is uniform and small, the oil in the piston oil chamber will be pushed into the transmission oil chamber by the return spring, and then the relative angle between the impeller and the distribution shaft is maintained. The piston is in a higher position, the pressure ring in the distribution assembly is less, the force of the resistance sleeve around the revolving gear is smaller, and the rotation resistance of the revolving gear is also smaller. Only a small part of the fixed speed on the fixed speed gear is transmitted to the first tooth surface through the revolving gear. The second tooth surface fixed relative to the first tooth surface also has only a smaller speed. The relay gear speed is low, and the distribution shaft and impeller speeds are also at low values.

[0018] When there is material agglomeration at the position of the auxiliary agitator wheel, the torque that needs to be transmitted between the wheel disc and the distribution shaft is large, and the oil in the transmission oil chamber is squeezed into the piston oil chamber in large quantities. The piston is in a lower position, and the return spring is compressed to a large extent. At this time, the piston end has a large extrusion force on the pressure ring, and the resistance sleeve is compressed to a large extent. The resistance sleeve hugs the revolving gear and makes it rotate poorly. The revolving gear and the first tooth surface have the same maximum revolving speed around the power transmission shaft, and the second tooth surface transmits the maximum speed to the relay gear; thereby, the speed of the power transmission shaft is distributed to different auxiliary agitators with unequal speed.

[0019] The gap surface path at the position where the wheel disc and the discharge plate are rotatably connected has a bend that first rises and then falls.

[0020] The rotating connection between the impeller and the discharge plate will come into contact with the material during the mixing process, and the rising path prevents material particles from continuously drilling into the gap under the action of gravity.

[0021] The mixing device further comprises an overflow pipe, which extends from the outside of the shell, one end of the overflow pipe is connected to the feed port, and the other end of the overflow pipe is connected to the bottom of the discharge plate.

[0022] The overflow pipe prevents excessive addition of material into the shell and feeds it into a straight discharge channel.

[0023] The turning drive is hydraulic. When the discharge plate turns over to discharge, the pressure it receives is the entire weight of the material, and it requires a lot of force to open. Hydraulic drive is relatively low in cost compared to high-power motors.

[0024] A horizontal spray pipe is provided on the upper part of the shell. The spray pipe introduces the liquid components to be added from the outside and sprays them onto the materials during the mixing process. It can also be used as a heat dissipation spray during the mixing process.

[0025] The observation window on the side of the shell makes it easy to check the stirring and mixing conditions inside the shell.

[0026] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention migrates materials over a large range through two main blades. During the migration process, some agglomerated materials are broken up by the auxiliary stirring wheel at the bottom. The auxiliary stirring wheel can also automatically distribute the proportion of the rotation speed obtained from the force transmission shaft according to the perception of the surrounding agglomeration situation, thereby preventing the already uniform material from being repeatedly stirred and wasting energy.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] A premixed powder mixing device with a powder block crushing function, the mixing device includes a shell 1, a main power drive 2, a rotor assembly 3, a feed port 41, a discharge plate 51, a flip drive 52, and an auxiliary stirring assembly 6. The side wall of the shell 1 extends out of a support to install the main power drive 2, the rotor assembly 3 is rotatably installed on the side wall of the shell 1, the rotor assembly 3 penetrates into and out of the shell 1, and the end of the rotor assembly 3 is transmission connected to the main power drive 2. The feed port 41 is set at the top of the shell 1, and the discharge plate 51 is installed at the bottom of the shell 1. The discharge plate 51 can be flipped at the bottom of the shell 1 to open or close the inner cavity of the shell 1. The flip drive 52 is installed on the bottom side wall of the shell 1, and the flip drive 52 is transmission connected to the discharge plate 51. The auxiliary stirring assembly 6 is installed on the discharge plate 51, and the auxiliary stirring assembly 6 is provided with a rotating structure facing the direction of the inner cavity of the shell 1.

[0039] like Figures 1 to 4 As shown, the material is added into the inner cavity of the shell 1 from the feed port 41. At this time, the discharge plate 51 remains horizontal, and a relatively closed chamber is formed in the shell 1. The rotor assembly 3 performs the main stirring action of the material in the shell 1, and carries the material to migrate over a large range, collide with each other, etc., so that the agglomerated material is broken and the various original materials are fully mixed. The auxiliary stirring assembly 6 crushes and shears some material blocks retained at the bottom of the chamber, because the probability of agglomerated materials appearing here is greater. For local positions such as corners where the rotor assembly 3 is not easy to touch the pole, the auxiliary stirring assembly 6 performs stirring and mixing operations, and cooperates with the rotor assembly 3 to perform a complete premixed powder mixing operation. After the material stirring and mixing is completed, the discharge plate 51 is driven to flip, the bottom of the shell 1 is opened, and the material falls downward to be bagged or transported to other subsequent processing steps.

[0040] The rotor assembly 3 includes a main shaft 31, a first main blade 32, and a second main blade 33. The main shaft 31 is rotatably mounted in a bearing seat on the outer surface of the shell 1. The main shaft 31 is transmission-connected to the active power drive 2. The first main blade 32 and the second main blade 33 are rotatably mounted on the main shaft 31. The first main blade 32 and the second main blade 33 are spiral blades with opposite rotation directions. The direction of the first main blade 32 and the second main blade 33 is adjustable.

[0041] like Figure 3 、 4 As shown, two main blades rotate on the main shaft 31 with different rotation directions. If they rotate in the same direction, then they can push the material in the shell 1 to the middle or to the sides under different rotation directions of the main shaft 31. If they rotate in different directions, then the material will be pushed toward one end. Continuously changing the rotation direction can allow the material to migrate in the shell 1 and increase the mixing effect.

[0042] The rotor assembly 3 also includes a steering switching gear set arranged at the end of the main shaft 31. The steering switching gear set serves as an intermediate piece to establish transmission between the first main blade 32, the second main blade 33 and the main shaft 31. The steering switching gear set can switch the transmission direction from the main shaft 31 to the first main blade 32, the second main blade 33.

[0043] The gear set can use external-external gear meshing and internal-external gear meshing to establish different directional transmissions. When switching the direction of the two main blades, just turn the gear set separately. Although the torque on the main shaft 31 is large and the speed is low, it is still recommended to switch the direction of the two main blades only when the main shaft 31 stops.

[0044] The auxiliary stirring assembly 6 includes an auxiliary motor 61, a force transmission shaft 62, an auxiliary stirring wheel 63, and a speed matching assembly 64. The auxiliary motor 61 is installed on the lower surface of the discharge plate 51, and the force transmission shaft 62 is rotatably installed under the discharge plate 51. The axis of the force transmission shaft 62 is in the horizontal direction. The force transmission shaft 62 is connected to the auxiliary motor 61 by transmission. There are the same number of auxiliary stirring wheels 63 and the speed matching assembly 64. The auxiliary stirring wheel 63 passes through the discharge plate 51 and is rotatably connected to the discharge plate 51. The auxiliary stirring wheel 63 establishes transmission with the force transmission shaft 62 through the speed matching assembly 64.

[0045] The speed matching component 64 transmits different speeds according to the torque uniformity during the rotation of the auxiliary stirring wheel 63. When the torque fluctuation of the auxiliary stirring wheel 63 is large, the speed transmitted from the power transmission shaft 62 to the auxiliary stirring wheel 63 is increased.

[0046] like Figure 4 、 5 As shown, several auxiliary stirring wheels 63 rotate under the main blades to fully crush and evenly mix some agglomerated materials retained here. The auxiliary stirring wheel 63 can reflect whether there are agglomerates in the area it covers through torque fluctuations. If the material is completely uniform, then the torque on the auxiliary stirring wheel 63 here is also uniform, and it only needs to move at a lower speed. If there are some agglomerated materials, there will inevitably be collisions during the contact process between the auxiliary stirring wheel 63 and the material, and the torque will also fluctuate. Therefore, the auxiliary stirring wheel 63 in contact with the agglomerated material takes greater power from the power transmission shaft 62 to perform crushing operations, thereby realizing power distribution within the auxiliary stirring component 6.

[0047] The auxiliary stirring wheel 63 includes a wheel disc 631, a force distribution shaft 632, a piston 633, a return spring 634, and a relay gear 635. The upper part of the wheel disc 631 is provided with blades, and the lower part of the wheel disc 631 is a rotating body rotatably mounted on the discharge plate 51. The lower end of the wheel disc 631 is axially engaged with the force distribution shaft 632. The wheel disc 631 and the force distribution shaft 632 are relatively rotatable. A transmission oil chamber 6311 is provided at the lower part of the wheel disc 631. The head portion connecting the force distribution shaft 632 and the wheel disc 631 is radially provided with an oil hole 6321 connecting the outer surface and the center. A piston oil chamber 6322 is provided at the end of 632 away from the wheel disc 631. An oil hole 6321 connects the transmission oil chamber 6311 and the piston oil chamber 6322. A piston 633 is slidably disposed in the piston oil chamber 6322. The end of the piston 633 away from the wheel disc 631 extends outside the distribution shaft 632. A return spring 634 is provided between the end surface of the piston 633 and the bottom surface of the piston oil chamber 6322. When the wheel disc 631 and the distribution shaft 632 rotate relative to each other, the volume of the transmission oil chamber 6311 decreases. A relay gear 635 is fixed to the outer surface of the distribution shaft 632.

[0048] A fixed speed gear 621 is provided at the position of each speed matching assembly 64 on the power transmission shaft 62. The speed matching assembly 64 includes a revolution frame 641, a revolution gear 642, a resistance sleeve 643, a pressure ring 644, and a speed change gear 645. The revolution frame 641 is rotatably mounted on the power transmission shaft 62. A plurality of revolution gears 642 are provided at the end of the revolution frame 641 along the radial direction. The resistance sleeve 643 is pressed on the end of the revolution frame 641 by the pressure ring 644. The resistance sleeve 643 covers the rotating shaft portion of the revolution gear 642. The resistance sleeve 643 is elastic. The pressure ring 644 floats radially along the end of the revolving frame 641, and the outer surface of the pressure ring 644 is slidably pressed against the end of the piston 633. The speed change gear 645 is rotatably installed on the power transmission shaft 62. The speed change gear 645 has a first tooth surface 6451 and a second tooth surface 6452. The first tooth surface 6451 and the second tooth surface 6452 both rotate with the power transmission shaft 62 as the axis. The revolving gear 642 is respectively engaged with the first tooth surface 6451 and the fixed speed gear 621, and the second tooth surface 6452 is engaged with the relay gear 635.

[0049] like Figures 5 to 8As shown, the auxiliary stirring wheel 63 senses the material agglomeration situation in its local area through the two-section shaft. If the resistance is uniform and small, the oil in the piston oil chamber 6322 will be pushed into the transmission oil chamber 6311 by the return spring 634, and then the relative angle between the wheel disc 631 and the force distribution shaft 632 is maintained. The piston 633 is in a higher position, the pressure ring 644 in the speed distribution assembly 64 is less pressed, the force of the resistance sleeve 643 around the revolving gear 642 is smaller, and the rotational resistance of the revolving gear 642 is also smaller. Only a small part of the fixed speed on the fixed speed gear 621 is transmitted to the first tooth surface 6451 through the revolving gear 642. The second tooth surface 6452 fixed relatively to the first tooth surface 6451 also has only a smaller speed. The speed of the relay gear 635 is low, and the speeds of the force distribution shaft 632 and the wheel disc 631 are also at a low value.

[0050] When there is material agglomeration at the position of the auxiliary stirring wheel 63, the torque that needs to be transmitted between the wheel disc 631 and the distribution shaft 632 is large, and the oil in the transmission oil chamber 6311 is squeezed into the piston oil chamber 6322 in large quantities. The piston 633 is in a lower position, and the return spring 634 is compressed to a large extent. At this time, the end of the piston 633 exerts a large extrusion force on the pressure ring 644, and the resistance sleeve 643 is compressed to a large extent. The resistance sleeve 643 embraces the revolving gear 642 to prevent it from rotating smoothly. The revolving gear 642 and the first tooth surface 6451 have the same maximum revolving speed around the force transmission shaft 62, and the second tooth surface 6452 transmits the maximum speed to the relay gear 635; thereby, the speed of the force transmission shaft 62 is distributed to different auxiliary stirring wheels 63 with unequal speed.

[0051] The gap surface path at the position where the wheel 631 is rotatably connected to the discharge plate 51 has a bend that first rises and then descends.

[0052] like Figure 5 As shown, the rotational connection position between the wheel 631 and the discharge plate 51 will contact the material during the mixing process, and the upward path prevents the material particles from continuously drilling into the gap under the action of gravity.

[0053] The mixing device further includes an overflow pipe 42 , which extends from the outside of the shell 1 . One end of the overflow pipe is connected to the feed port 41 , and the other end of the overflow pipe 42 is connected to the bottom of the discharge plate 51 .

[0054] The overflow pipe 42 prevents excessive addition of material in the shell 1 and feeds it into a straight discharge channel.

[0055] The turning drive 52 is hydraulically driven. When the discharge plate 51 is turned over for unloading, the pressure it receives is the entire weight of the material, and a large force is required to open it. The hydraulic pressure is relatively low in cost compared to a high-power motor.

[0056] A horizontal spray pipe 7 is provided in the upper part of the housing 1. The spray pipe 7 introduces liquid components to be added from the outside and sprays them onto the materials in the mixing process. It can also be used as a heat dissipation spray during the mixing process.

[0057] An observation window 8 is provided on the side of the housing 1 , which allows for easy viewing of the mixing conditions within the housing 1 .
