DETAILED DESCRIPTION

[0023] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] See also Figures 1 to 5 A high-efficiency mixer according to a preferred embodiment of the present invention comprises a silo positioning frame 2 for mounting a silo 1 and a positioning frame driving device 3 for driving the silo positioning frame to rotate, the silo positioning frame comprises a base 201, a pressing plate 202 corresponding to the base and a base driving device 203 for driving the base to rise and fall relative to the pressing plate, one of the base and the pressing plate is arranged at the output end of the base driving device, the other of the base and the pressing plate is fixedly connected to the body of the base driving device, and the fixing part of the base driving device is connected to the output shaft of the positioning frame driving device.

[0025] The high-efficiency mixer of the present invention has a silo positioning frame, which realizes the rapid installation and replacement of the silo, so that it can mix the next batch of materials while the silo is unloading. The detachable installation of the silo also facilitates the operator to unload the materials, thereby improving the efficiency of material mixing and output. Among them, the positioning frame driving device is used to realize the rotation of the silo positioning frame, thereby driving the silo on the silo positioning frame to rotate, and finally realize the mixing of the materials in the silo. During the specific operation, the operator first places the silo filled with materials on the base of the silo positioning frame, and then the base driving device drives the base to translate relative to the pressing plate until the silo is pressed between the pressing plate and the base, and then the output end of the positioning frame driving device drives the silo positioning frame to rotate, thereby driving the silo on the silo positioning frame and the materials in the silo to rotate. After the materials in the silo are completely mixed, the positioning frame driving device stops, and then the base driving device drives the base to move in the opposite direction mentioned above, thereby loosening the silo, and at this time the operator can take out the silo from the silo positioning frame by hand or by forklift and unload it. During the process of unloading the silo, the operator can install another silo filled with materials on the silo positioning frame and perform mixing operations on them in the same way as above. The positioning frame driving device is a device with a rotational driving function, which is preferably a motor 301 and a reducer 302. During specific implementation, the input shaft of the reducer is connected to the output shaft of the motor, the body of the reducer is installed in the main frame 4 next to the silo positioning frame, and the output shaft of the reducer is connected to the body of the base driving device. The base driving device is a device with a translational driving function, which can be manual, electric, pneumatic or hydraulic, and is preferably a cylinder. During specific implementation, the number of cylinders is two, and the cylinder bodies of the two cylinders are respectively arranged on the left and right sides of the mounting plate 5, the cylinder barrel of the cylinder is connected to the base, one end of the pressing plate is fixed on the mounting plate or the piston rod of the cylinder, and the mounting plate is connected to the output shaft of the reducer. Under this installation method, the output end of the cylinder drives the base to move. In addition, the installation positions of the base and the pressing plate can also be swapped, as long as the pressing plate and the base can press the silo under the drive of the base driving device. During use, the cylinder can be supplied with oil through the hydraulic system 6 arranged in the main body to prevent the silo from loosening during the mixing process. The output end of the hydraulic system can be connected to the oil cylinder through a pipeline (not shown) and a slip ring 7. Here, the slip ring is an outsourced part, which is an electrical component responsible for connecting the rotating body and transmitting energy and signals. According to the transmission medium, the slip ring is divided into an electric slip ring, a fluid slip ring, and a smooth slip ring. It is usually installed at the rotation center of the equipment and is mainly composed of two parts: rotating and stationary. The rotating part is connected to the rotating structure of the equipment and rotates with it, which is called the "rotor", and the stationary part is connected to the fixed structure of the equipment, which is called the "stator". The slip ring as a whole relies on the elastic lap principle, the rolling lap principle, or the sealing principle, as well as the ingenious design of the motion structure and the sealing structure, the precise parts production and coordination, and the reasonable selection of materials, etc., to form a stable and reliable rotating connection system.In this embodiment, the slip ring is a conductive slip ring with conductive, oil and gas conductive functions. It is installed on the main shaft of the reducer and is connected to the hydraulic system, cylinder, electrical components and other components through oil pipes, air pipes and wires.

[0026] In addition, the base driving device can also be an electric cylinder, a pneumatic cylinder or an ordinary manual lifting device. When the base driving device is a manual lifting device, the operator can lock the fixed part and the movable part by tightening the bolts.

[0027] In summary, the material bin of the high-efficiency mixer of the present invention is easy to replace, which enables the mixing and outputting operations of materials to be performed separately, thereby enabling the high-efficiency mixer to mix materials during unloading, and also facilitating the operator to output materials.

[0028] Preferably, the high-efficiency mixer of the present invention further comprises a main frame 4, the body of the positioning frame driving device is fixedly mounted on the main frame, the base driving device is an oil cylinder, and a hydraulic system 6 for supplying oil to the oil cylinder is also arranged on the main frame.

[0029] Preferably, in the high-efficiency mixer of the present invention, the base comprises a bottom plate 20101 connected to the output end of the base driving device, a connecting plate 20102 fixedly connected to the bottom plate, and a bin positioning seat 20103 is provided on the surface of the connecting plate.

[0030] The setting of the silo body positioning seat realizes the positioning of the silo. The setting of the bottom plate and the connecting plate in combination with the active device of the base realizes the lifting and lowering of the silo. Among them, the silo body positioning seat is a box-shaped structure with an opening on the top, and its top has a flange plate 20105 for installing a nylon ring 20104. When in use, the inner side of the nylon ring contacts the side wall of the silo body. The bottom of the silo body positioning seat has a through hole for the sealing plate mounting seat 20106 to pass through. The top of the sealing plate mounting seat is connected to the sealing plate 20106, and its bottom is connected to the connecting plate 20102.

[0031] Preferably, in the high-efficiency mixer of the present invention, a sealing plate mounting seat 20106 is provided on the connecting plate, the top of the sealing plate mounting seat is located in the bin body positioning seat, a sealing ring 9 is provided on the outside of the sealing plate mounting seat, a sealing plate 20106 is provided on the top of the sealing plate mounting seat, the sealing plate is located above the sealing ring, and an exhaust hole is provided on the sealing plate.

[0032] The setting of the sealing ring realizes the sealing of the sealing valve 10 at the discharge port of the silo, thereby preventing external air from entering the interior of the silo when the silo rotates. The silo includes a silo body 101, a discharge port 102 is provided at the bottom of the silo body, the bottom of the silo body is a truncated cone that shrinks toward the discharge port, a hollow sealing valve 10 is provided at the discharge port, and a retaining ring 1002 is provided at the bottom of the sealing valve. When in use, after the operator places the bottom of the silo into the silo body positioning seat, the operator can inflate the sealing ring through an air pump. After inflation, the sealing ring gradually expands until it is in close contact with the retaining ring at the bottom of the valve body, thereby sealing the gap between the sealing plate and the valve body. After the valve body is sealed, the operator can evacuate the valve body through the exhaust hole on the sealing plate, so that the air pressure in the silo body presses the sealing valve toward the discharge port of the silo body, and finally achieves the sealing of the silo body.

[0033] Preferably, in the high-efficiency mixer of the present invention, the silo is a square silo, the inner cavity of the silo is also a square inner cavity, and the side length direction 12 of the rectangular cross section of the square inner cavity is inclined to the central axis direction of the silo positioning frame rotating shaft 13.

[0034] This arrangement improves the mixing efficiency of the materials. In specific implementation, the square silo and the mounting plane 14 of the driving component are inclined at an angle of 15° (±3°), so that the contact area and friction coefficient between the materials can be increased during the mixing rotation, thereby accelerating their physical changes and making the materials more quickly and evenly mixed.

[0035] Preferably, in the high-efficiency mixer of the present invention, the silo includes a silo body 101, a discharge port 102 is arranged at the bottom of the silo body, the bottom of the silo body is a truncated cone that shrinks toward the discharge port, a hollow sealing valve 10 is arranged at the discharge port, the sealing valve includes a valve body 1001, a retaining ring 1002 is provided at the bottom end of the valve body, and a first sealing ring 1003 is arranged on the periphery of the retaining ring.

[0036] The setting of the sealing valve realizes the sealing of the bin body, which can ensure that the material does not come into contact with the outside air, thereby increasing the stability of the material. In specific implementation, it can be made of food-grade environmentally friendly silicone or natural rubber.

[0037] The sealing plate is arranged so that a vacuum cavity can be formed between the valve body, the sealing plate and the sealing ring, so that the operator can extract the air in the valve body through the air extraction hole on the sealing plate. After the air in the valve body is extracted, the valve body moves toward the discharge port under the action of the air pressure in the silo and the gravity of the material, so that the first sealing ring outside the retaining ring is in closer contact with the inner side wall of the silo, and finally the sealing effect of the silo is improved. In specific implementation, the sealing plate is connected to the base through the sealing plate mounting seat 20106. During specific operation, the sealing ring gradually expands under the action of an external air source until its outer side is in close contact with the inner side of the retaining ring, thereby achieving sealing of the gap between the sealing plate and the sealing valve. Thereafter, the operator exhausts air through the exhaust hole on the sealing plate, and the air pressure of the retaining ring in the vacuum chamber formed by the sealing plate, the sealing ring, the retaining ring and the valve body gradually decreases. As the air pressure in the vacuum chamber decreases, a certain pressure difference is generated on both sides of the valve body. The air pressure in the bin body moves the valve body connecting the retaining ring and the first sealing ring outside the retaining ring toward the silo discharge port. Since the bottom of the bin body is an inverted cone, as the valve body moves downward, the first sealing ring on the valve body contacts the inner wall of the bin body more closely, thereby achieving effective sealing of the bin body.

[0038] Preferably, the valve body of the high-efficiency mixer of the present invention is in a truncated cone shape.

[0039] This design creates an angle between the surface of the sealing valve and the inner conical surface of the lower part of the silo, and the angle is preferably 75°, which can prevent the accumulation and agglomeration of materials on the lower conical surface of the silo due to centrifugal force, thereby ensuring that there are no dead angles on the lower conical surface of the silo when the materials are mixed, which can effectively ensure the best quality of the mixed materials.

[0040] Preferably, in the high-efficiency mixer of the present invention, a material inlet 103 is provided at the top of the bin body, a bin cover 104 is provided at the material inlet of the bin body, and a connecting column 105 is also provided on the bin body.

[0041] The setting of the feed port and the bin cover realizes the input of materials, that is, the sealing of the bin body. In specific implementation, the bin cover is set at the feed port through a clamp 106, and a second silicone sealing ring is also provided between the bin cover and the bin body.

[0042] Preferably, in the high-efficiency mixer of the present invention, positioning pins 15 are provided on the surface of the pressing plate.
