Abstract
Description
Technical Field
[0001] This utility model relates to the field of fly ash treatment technology, specifically a dehydration and mixing device. Background Technology
[0002] Fly ash is a type of fine particulate matter produced by combustion processes such as municipal solid waste incineration and industrial waste incineration. These particles often contain toxic and harmful substances such as heavy metals and dioxins, as well as a certain amount of moisture. If discharged directly without treatment, it will not only occupy a large amount of storage space but also pollute the environment. Therefore, there is an urgent need for equipment that can dehydrate fly ash to facilitate subsequent treatment. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides the following technical solution: a dewatering and mixing device, comprising a frame, a mounting bracket fixedly installed on the top of the frame, a crushing and mixing machine fixedly installed inside the frame, a feed hopper fixedly installed on the top of the crushing and mixing machine, a dewatering disc provided on the top of the mounting bracket, a fixed plate fixedly installed on the top side of the mounting bracket, a pressure stabilizing chamber provided at the center of the fixed plate, and a main shaft drive for driving the dewatering disc fixedly installed on the top side of the mounting bracket. The main shaft drive drives the dewatering disc, causing the fly ash inside to be dewatered under centrifugal force. The dewatered fly ash is then fed into the crushing and mixing machine through the feed hopper, and a stabilizing plasticizer is added inside for thorough mixing.
[0004] As an optimization, the dehydration disc has an outer edge on its outer side and several sets of arrayed partitions inside.
[0005] As an optimization, a positioning element is provided on the top side of the mounting bracket corresponding to the outer edge. The positioning element guides and positions the outer edge, improving the stability of the dehydration disc rotation.
[0006] As an optimization, the positioning element includes a bracket fixedly mounted on the top side of the mounting frame, with a roller rotatably connected to the top of the bracket, and the roller rolling against the outer side of the outer edge.
[0007] As an optimization, a servo motor is fixedly installed on one side of the front of the crushing and mixing machine, and a stirring rod is rotatably connected inside the crushing and mixing machine. The middle part of the stirring rod is fixedly installed at one end of the output shaft of the servo motor, and a bearing is provided on the outside of the output shaft of the servo motor.
[0008] As an optimization, the stirring rod has a spiral structure, and the spiral portions of the stirring rods on both sides are interlaced.
[0009] The beneficial effects of this utility model are:
[0010] This dewatering and mixing equipment drives the dewatering disc to rotate via a main shaft drive, thereby centrifugally dewatering the fly ash inside the disc and further reducing the chloride ion concentration in the fly ash. The dewatered fly ash then flows downward into the crushing and mixing machine. By starting the servo motor, the mixing rods on both sides can be rotated, and a stabilizing plasticizer is poured into the crushing and mixing machine. This allows the fly ash to be fully mixed with the stabilizing plasticizer during crushing, thereby reducing the moisture content of the fly ash and changing its physical properties to meet the requirements for plasticization.

[0015] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-2A dewatering and mixing device includes a frame 1, a mounting frame 2 fixedly installed on the top of the frame 1, a crushing and mixing machine 3 fixedly installed inside the frame 1, a feed hopper 4 fixedly installed on the top of the crushing and mixing machine 3, a dewatering disc 5 set on the top of the mounting frame 2, a fixed disc 6 fixedly installed on the top side of the mounting frame 2, a pressure stabilizing chamber 7 set in the center of the fixed disc 6, and a main shaft drive 8 for driving the dewatering disc 5 fixedly installed on the top side of the mounting frame 2. The main shaft drive 8 drives the dewatering disc 5, so that the fly ash inside it is dewatered under the action of centrifugal force. Then, the dewatered fly ash is introduced into the crushing and mixing machine 3 through the feed hopper 4, and a stabilizing plasticizer is added inside for thorough mixing, thereby reducing the moisture content of the fly ash and changing its physical properties to meet the requirements of plasticity.
[0018] Please see Figure 1-2 The dewatering disc 5 has an outer edge 9 on its outer side and several sets of arrayed partitions 10 inside it. The fly ash is isolated by the several sets of partitions 10, which facilitates dewatering in batches and improves dewatering efficiency.
[0019] Please see Figure 1-2 A positioning element is provided on the top side of the mounting frame 2 corresponding to the outer edge 9. The positioning element guides and positions the outer edge 9, improving the stability of the rotation of the dehydration disc 5. The positioning element includes a bracket 11 fixedly installed on the top side of the mounting frame 2. A roller 12 is rotatably connected to the top of the bracket 11, and the roller 12 rolls against the outer side of the outer edge 9.
[0020] Please see Figure 3 A servo motor 13 is fixedly installed on one side of the front of the crushing and mixing machine 3. An agitator 14 is rotatably connected inside the crushing and mixing machine 3. The agitator 14 has a spiral structure, and the spiral parts of the agitator 14 on both sides are interlaced. The middle part of the agitator 14 is fixedly installed at one end of the output shaft of the servo motor 13. A bearing 15 is provided on the outside of the output shaft of the servo motor 13. By starting the servo motor 13, the agitator 14 on both sides will be driven to rotate inside the crushing and mixing machine 3, thereby agitating the fly ash after dehydration inside, so that the fly ash and the stabilizer plasticizer are fully mixed.
[0021] In use, the dewatering disc 5 is first driven by the main shaft drive 8, which makes the dewatering disc 5 rotate. Under the action of centrifugal force, the fly ash inside is dewatered. The dewatered fly ash will fall into the crushing and mixing machine 3. At this time, the servo motor 13 is started to drive the stirring rods 14 on both sides to rotate. At the same time, the stabilizing plasticizer is poured into the crushing and mixing machine 3 to make it fully mixed with the fly ash.
[0022] In summary, this dewatering and mixing equipment drives the dewatering disc 5 to rotate via the main shaft drive 8, thereby centrifugally dewatering the fly ash inside the dewatering disc 5, achieving the dewatering effect and further reducing the chloride ion concentration in the fly ash. The dewatered fly ash will then enter the crushing and mixing machine 3. By starting the servo motor 13, the stirring rods 14 on both sides can be rotated. At the same time, a stabilizing plasticizer is poured into the crushing and mixing machine 3, so that the fly ash can be fully mixed with the stabilizing plasticizer while being crushed, thereby reducing the moisture content of the fly ash and changing its physical properties to meet the requirements for plasticization.
