Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a mixing device for preparing CFB target area plastics. Background Art

[0002] The plastic material for CFB target area is a specially designed wear-resistant material, which is used in the target area of ​​the circulating fluidized bed boiler (CFB), which is the key part of the flue gas denitrification (SNCR) system. This material needs to have good wear resistance and corrosion resistance to adapt to the working environment of high temperature, wear and corrosion, while maintaining a certain toughness to avoid cracks during use.

[0003] The plastic material specially used for CFB target area is composed of aggregate, fine powder, reinforcing agent, composite binder, composite mineralizer, composite plasticizer and moisturizing agent. The preparation method is to mix the above raw materials in a certain proportion, and then make the final product through the steps of stirring, molding, drying and curing.

[0004] The mixing equipment for preparing CFB target area plastics should have efficient mixing capabilities to ensure that various raw materials can be evenly mixed to form plastics with excellent wear resistance and corrosion resistance. Therefore, there is an urgent need for a mixing equipment for preparing CFB target area plastics. However, the existing mixing equipment for preparing CFB target area plastics has a single stirring method, poor stirring effect, and is inconvenient to clean. Utility Model Content

[0005] In view of the above problems, the utility model discloses a mixing device for preparing CFB target area plastics.

[0006] The technical solution of the utility model is: a mixing device for preparing CFB target area plastic, comprising a mixing body, a mixing component arranged in the mixing body;

[0007] The mixing assembly includes a mounting main frame that can rotate circumferentially along the inner wall of the mixing body, a plurality of mounting rods circumferentially arranged at the bottom end of the mounting main frame, a plurality of mixing mounting plates sleeved on the outer walls of the mounting rods, a plurality of mixing support rods arranged on the outer walls of each of the mixing mounting plates, a planetary gear assembly arranged at the bottom end of the mixing mounting plate, and a driving element that drives the planetary gear assembly to rotate, and each mounting rod is connected to the planetary gear assembly.

[0008] Furthermore, a cylinder cover is movably connected to the upper end of the mixing body, and a discharge port is provided at the bottom end of the mixing body.

[0009] Note: During the mixing process, the barrel cover seals and protects the mixing body, ensuring that no foreign matter enters the mixing body during the mixing process, while preventing the plastic raw materials in the internal CFB target area from leaking, causing resource waste or environmental pollution.

[0010] Furthermore, each mixing installation plate is provided with a mounting recess at one end close to the inner wall of the mixing body, the mounting recess is connected with a connecting seat via a horizontally placed hydraulic drive element, and a cleaning brush is movably connected to the connecting seat.

[0011] Description: When the mixing is completed, the connecting seat and the cleaning brush are driven out of the installation recess by the hydraulic driving element. When the mixing mounting plate moves with the mounting rod, the cleaning brush will move along the inner wall of the mixing body to clean the mixing body. When not in use, the connecting seat and the cleaning brush are driven by the hydraulic driving element to be moved back into the installation recess. The above process will not affect the normal progress of the mixing work, but can also automatically clean the inner wall of the mixing body regularly, reduce the waste of wall-hanging materials, and thus improve the utilization rate of the materials after mixing.

[0012] Furthermore, a pull-out cover is slidably connected to the outer wall of the mixing installation plate near the installation recess in the vertical direction.

[0013] Note: When the hydraulic drive element drives the connecting seat and the cleaning brush to move back into the installation recess, the pull-out cover can be slid from the outer wall of the mixing installation plate from top to bottom to cover the installation recess and prevent the material from entering the installation recess, which will not only cause material waste but also increase the difficulty of cleaning.

[0014] Furthermore, a placement seat is provided at the bottom end of the mixing body, and a supporting leg is provided at the bottom end of the placement seat, and a moving wheel and a brake assembly are provided at the bottom end of the supporting leg.

[0015] Description: The mixer body is supported by a placement seat and a support leg at the bottom thereof. At the same time, the moving wheels facilitate movement of the equipment, and the brake assembly is used to position the equipment as a whole to avoid movement during mixing.

[0016] Beneficial effects of the utility model:

[0017] When the mixing equipment for preparing CFB target area plastic material of the utility model is in use, a mounting main frame which can rotate along the circumferential direction of the inner wall of the mixing body is provided, so that each mixing mounting plate is driven to revolve along the inner wall of the mixing body. At the same time, each mixing mounting plate is started to rotate by itself through a planetary gear assembly. Through the two stirring modes of revolution and rotation, the stirring effect of the raw materials is greatly improved, so that the performance of the prepared CFB target area plastic material meets the use requirements. By providing a hidden cleaning brush on the side wall of each mixing mounting plate, the cleaning brush and the mixing mounting plate are set as an integrated structure, which will not affect the normal progress of the mixing work, and can automatically clean the inner wall of the mixing body regularly, reduce the waste of wall-hanging materials, and thus improve the utilization rate of the materials after mixing.
