Description

Technical Field

[0001] The present application relates to the technical field of material automatic processing equipment, and particularly relates to a mass-breaking device for mixing and mass-breaking, and a mixing device equipped with the mass-breaking device. Background Art

[0002] During the rotation mixing process of a bucket elevator rotary mixer, due to reasons such as material properties, caking phenomena are likely to occur, affecting the mixing uniformity of the materials.

[0003] Most existing bucket elevator mixing devices do not have a flying knife mass-breaking device, or place the flying knife mass-breaking device on the hopper. When caking occurs in the materials, the bucket elevator mixer without a flying knife mass-breaking device cannot achieve uniform mixing. For a bucket elevator mixing device with a flying knife mass-breaking device set on the hopper, when a mixer is equipped with multiple hoppers, each hopper needs to be equipped with a set of flying knife mass-breaking devices, and manual assembly and disassembly are required, which is time-consuming and laborious, with low automation. Moreover, due to the poor rigidity of the hopper where the flying knife mass-breaking device is placed, the rotation speed of the flying knife mass-breaking device is limited, resulting in poor mixing uniformity of the materials.

[0004] Therefore, there are still many defects in the existing bucket elevator mixing devices, and it is urgent to propose a new technical solution to solve the problems existing in the prior art. Content of the Utility Model

[0010] Furthermore, the airbag inflation port is installed at the first end of the flange and is arranged opposite to the airtight joint. The airbag is close to the second end of the flange, and the airbag inflation port is connected to the airbag by a gas pipeline.

[0011] Furthermore, the mounting plate is connected to the first end of the flange. Screw mounting holes are provided on the mounting plate, and the mounting plate is firmly connected to the mixer frame by screws passing through the screw mounting holes.

[0012] Further, a plug rod is integrally provided inside the cutter shaft. The central axis of the plug rod coincides with the central axis of the cutter shaft.

After the airbag is inflated and bulged, it is closely attached to the opening of the hopper.

[0015] Compared with the prior art, the present application has at least the following beneficial effects:

[0016] 1. This application is based on further analysis and research of the problems in the prior art. It is recognized that in some current mixing devices, there is no agglomerate-breaking device, resulting in poor mixing uniformity of the materials. In some other mixing devices, although an agglomerate-breaking device is configured, the agglomerate-breaking device is installed on the hopper. Due to the poor rigidity of the hopper, the rotation speed of the agglomerate-breaking device is limited, still resulting in poor mixing uniformity of the materials. In addition, the existing agglomerate-breaking devices are basically installed on the hopper by mechanical connection methods, with low automation, inconvenient installation and disassembly, and one agglomerate-breaking device can only be used in cooperation with one hopper. Therefore, this application provides an agglomerate-breaking device. By setting an installation plate on the agglomerate-breaking device, it can be adapted and fixed to the mixer frame, improving the fixing rigidity of the agglomerate-breaking device, thereby increasing the rotation speed and improving the mixing uniformity of the materials, and the installation is simple; further, in this application, the motor and the bearing seat are fixed on the flange plate, and an airbag, an airbag baffle, an airtight joint and an airbag inflation port are provided on the flange plate. A lip-type rotary seal ring is provided in the bearing seat. During use, the airbag on the flange plate is inflated through the airbag inflation port. After the airbag bulges, it automatically docks with the mixer hopper opening. The airbag baffle can prevent the airbag from being misaligned during the rotary mixing process, ensuring the sealing performance. At the same time, air can be introduced into the inner ring of the lip-type rotary seal ring through the airtight joint to achieve airtightness, playing a role in sealing and air lubrication; therefore, in this application, the automatic docking and loosening of the agglomerate-breaking device and the hopper are realized by inflating and deflating the airbag, improving the automation degree, and the agglomerate-breaking device is convenient to install and use.

[0017] 2. In this application, the motor and the bearing seat are installed and fixed through the flange plate. A lip-type rotary seal ring is provided in the bearing seat. The airtight joint installed on the flange plate is connected to the joint of the lip-type rotary seal ring through a gas pipeline. Further, an airbag and an airbag inflation port for inflating the airbag are provided on the flange plate. Therefore, the flange plate in this application plays a role in structural assembly connection, making the overall structure compact and highly integrated.

[0018] 3. In this application, the power output shaft of the motor and the cutter shaft are connected by flat key transmission, and the connection part of the two is located in the bearing seat. A bearing and a lip-type rotary seal ring are provided in the bearing seat. After the motor starts, it can drive the cutter shaft to rotate at a high speed, and the lip-type rotary seal ring can play a role in sealing and air lubrication under the inflation action of the airtight joint. The high-speed rotation of the cutter shaft can achieve full mixing of the materials in the hopper, improving the mixing uniformity of the materials.

[0019] 4. In this application, the cutter shaft is adaptively inserted into the power output shaft of the motor and is connected by a flat key to ensure the stability and safety of the flying knife assembly during high-speed rotation.

[0020] 5. The flying knife assembly in this application includes a knife shaft and a plurality of blades arranged on the knife shaft. The blades are regularly arranged or randomly arranged in the length direction of the knife shaft. When the knife shaft rotates, it drives the blades on it to rotate, realizing the function of breaking up agglomerates in the mixed material, improving the mixing uniformity of the material, shortening the rotational mixing time, and improving the mixing efficiency.

[0021] 6. Based on the agglomerate-breaking device provided in this application, this application also provides a mixing device. The agglomerate-breaking device is fixed on the mixing machine frame of the mixing device. Fastening the agglomerate-breaking device to the mixing machine frame through bolts and other connecting parts can improve the fixing rigidity of the agglomerate-breaking device, enabling the rotational speed of the agglomerate-breaking device to be increased. At the same time, an airbag is configured on the agglomerate-breaking device. The airbag is hermetically docked with the hopper through the airbag, realizing the automatic combination and separation of the agglomerate-breaking device and the hopper. The device has a high degree of automation, is easy to use, and can realize multiple hoppers sharing a set of agglomerate-breaking devices. Description of the Drawings
