Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mixing technology, and in particular relates to a double cone rotary internal stirring mixer. Background Technology
[0002] The double cone mixer is a high-efficiency, precise container-rotating and stirring type mixing machine, mainly used for the uniform mixing of various powdery and granular materials. It has a high degree of mixing and is suitable for industries such as magnetic powder, ceramics, chemicals, pharmaceuticals, and feed. Driven by a single electric motor, the cylinder is driven by a sprocket, and the stirring blades are driven by a V-belt. The structure is simple, the transmission is reliable, and maintenance is convenient. The double cone cylinder support bearings are equipped with mechanical seals for dust prevention, providing a reliable sealing effect. Powder leakage is prevented, and the bearings are protected from rapid wear and damage caused by material entering the bearings. The double cone cylinder inlet uses a quick-opening rotary valve, and the outlet uses a large-diameter 90° rotary valve, making it particularly convenient to use.
[0003] Because the mixing space of a double cone mixer can only be opened slightly, when the interior needs to be cleaned, it can only be cleaned through the small external loading and unloading openings, which makes cleaning the interior space of a conventional double cone mixer quite troublesome.
[0004] To address these issues, we propose a double-cone rotary internal mixing machine. Utility Model Content
[0005] The purpose of this invention is to solve the problem of the cumbersome internal space cleaning of conventional double cone mixers, and to propose a double cone rotary internal stirring mixer.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A double-cone rotary internal mixing mixer includes a mixer body. A rotating sleeve is fixedly connected to the rotating shaft of the mixer body. A first conical shell is fixedly connected to the lower part of the rotating sleeve. A second conical shell covers the upper part of the first conical shell. The lower end of the second conical shell is sealed to the first conical shell. A rotating seat is rotatably mounted on the side of the rotating sleeve. A bolt is threaded into the internal part of the rotating seat. A fastening block is fixedly connected to the outside of the second conical shell. The fastening block fastens onto the rotating sleeve, and the bolt is movably pressed against the outside of the fastening block. Loosening the bolt releases the fastening block. Rotating the bolt to the side removes the obstruction from the fastening block. Rotating the second conical shell causes the fastening block to rotate out of the rotating sleeve. The second conical shell can then be removed, significantly opening up the space between the first and second conical shells, facilitating cleaning of their interiors.
[0008] Preferably, the rotating sleeve includes a fixed ring, a pressure block, and a bearing seat. The pressure block is uniformly and fixedly connected to the upper part of the fixed ring. The fixed ring is fixedly connected to the rotating shaft of the mixer body, and the bearing seat is fixedly connected to the upper part of the fixed ring. The pressure block acts downwards on the retaining block, causing the retaining block to act downwards on the second conical shell, firmly pressing the lower end of the second conical shell against the first conical shell. After the retaining block is unscrewed from the pressure block, the rotating sleeve releases the retaining block and the second conical shell, facilitating the assembly and disassembly of the second conical shell.
[0009] Preferably, the rotating base includes a threaded seat, a rotating shaft, and a rotating block. The lower end of the threaded seat is fixedly connected to the upper end of the rotating shaft, the rotating shaft is rotatably mounted in a bearing housing, and the rotating block is rotatably mounted in the bearing housing. The threaded seat guides the bolt helix, allowing the bolt to tighten or loosen the locking block, facilitating the control of the bolt helix movement during tightening.
[0010] Preferably, the rotating base further includes a conical spring, the lower end of which is fixedly connected to the rotating block, and the upper end of which is fixedly connected to the bearing seat. After the bolt is loosened, the elastic force of the conical spring acts on the rotating block, which in turn acts on the rotating shaft, which in turn acts on the threaded seat, making it easy to rotate the bolt away from the second conical shell and the fastening block.
[0011] Preferably, the bolt includes a threaded rod and a knob, one end of which is fixedly connected to the knob, and the threaded rod is threaded into a threaded seat. The knob increases the operating lever length for tightening the threaded rod, facilitating manual operation of the bolt rotation.
[0012] Preferably, the bolt further includes a hemispherical block, which is fixedly connected to the threaded rod. When the threaded rod presses against the fastener, the hemispherical block is embedded in the fastener, increasing the stability of the bolt-fastener engagement position.
[0013] Preferably, the fastening block includes a block body with a groove on it. The hemispherical block is embedded in the groove, and the block body is movably locked within the pressure block. When the hemispherical block is pressed into the groove, the groove acts on the block body, pressing the block body tightly within the pressure block, thus increasing the stability of the connection between the rotating sleeve and the fastening block.
[0014] In summary, the technical effects and advantages of this utility model are as follows:
[0015] 1. Loosen the bolt to release the fastener block, then rotate the bolt to the side to remove the fastener block. Rotate the second conical shell to move the fastener block out of the rotating sleeve. Then remove the second conical shell to significantly open up the space between the first and second conical shells, making it easier to clean the inside of the first and second conical shells.
[0016] 2. By using the pressure block to act downwards on the buckle block, the buckle block acts downwards on the second conical shell, so that the lower end of the second conical shell is firmly pressed and closed on the first conical shell. After the buckle block is unscrewed from the pressure block, the rotating sleeve loosens the buckle block and the second conical shell, making it easy to disassemble and assemble the second conical shell.
[0017] 3. The threaded seat guides the bolt screw, allowing the bolt to tighten or loosen the threaded block, making it easy to control the movement of the bolt screw.
[0018] 4. After loosening the bolt, use the elastic force of the conical spring to act on the rotating block, which in turn acts on the rotating shaft, which in turn acts on the threaded seat, making it easy to rotate the bolt away from the second conical shell and the fastening block.
[0019] 5. When the threaded rod presses against the fastener block, the hemispherical block is embedded in the fastener block to increase the stability of the bolt and fastener block engagement position.
[0020] 6. When the hemispherical block is pressed into the groove, the groove acts on the block, pressing the block tightly into the pressure block, increasing the stability of the swivel and the fastening block connection. Attached Figure Description
