Description

Technical Field

[0001] This utility model relates to the field of clean coal processing technology, specifically to a clean coal sedimentation filtration centrifugal dewatering machine. Background Technology

[0002] Clean coal processing refers to the process of further dehydrating, grading, and storing high-quality coal obtained after raw coal has been crushed, screened, and washed. It typically includes centrifugal dehydration or pressure filtration to reduce moisture content, followed by grading according to particle size or intended use, and finally transporting or loading the coal into storage silos to ensure that the clean coal has lower ash and sulfur content and higher calorific value to meet the requirements of fuel or metallurgical industries.

[0003] Most existing centrifugal dewatering machines directly place the paddle inside the equipment and start centrifugal dewatering by rotation. However, this method tends to cause a large amount of material to accumulate at the bottom due to gravity, which means that the liquid needs to penetrate a thicker path to complete the centrifugation process, resulting in longer working time, reduced centrifugation efficiency, and inconvenience. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a fine coal sedimentation filtration centrifugal dewatering machine, which has the advantage of effectively shortening the liquid penetration path through the laying method to improve dewatering efficiency. It solves the problem that most existing centrifugal dewatering machines directly place the paddle inside the equipment and start centrifugal dewatering by rotation. However, this method easily leads to a large amount of material accumulating at the bottom due to gravity, which causes the liquid to need to penetrate a thicker path to complete the centrifugation process, resulting in longer working time and reduced centrifugation efficiency.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A fine coal sedimentation filtration centrifugal dewatering machine includes a drainage sleeve. The inner wall of the drainage sleeve is rotatably provided with a centrifugal dewatering cylinder with a drainage hole on the inner bottom wall and a separation hole on the inner wall. A drive frame extending to the top of the centrifugal dewatering cylinder is fixedly installed on the outside of the drainage sleeve. A centrifugal drive component for driving the centrifugal dewatering cylinder to rotate is fixedly installed inside the drive frame. A laying base ring that blocks the drainage hole and has a filtering function is placed on the inner wall of the centrifugal dewatering cylinder. A laying frame extending to the outside of the centrifugal dewatering cylinder and connected to the drive frame is movably arranged inside the laying base ring. A vertical drive component for driving the laying frame to move up and down is fixedly installed on the outside of the drive frame. The inner bottom wall of the drainage sleeve is funnel-shaped and a drainage valve is connected to the end.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the inner bottom wall of the drain sleeve is provided with a support platform, the top of the support platform is provided with a ball bearing that contacts the bottom wall of the centrifugal dewatering cylinder, and the inner wall of the drain sleeve is fixedly provided with a bearing that supports the side wall of the centrifugal dewatering cylinder.

[0010] Furthermore, the centrifugal drive component includes a first drive motor fixed inside the drive frame, a first drive tooth fixedly disposed on the outside of the output end of the first drive motor, and a toothed ring that meshes with the first drive tooth fixedly disposed on the outside of the centrifugal dehydration cylinder.

[0011] Furthermore, the laying frame consists of a laying cone and a rack fixed at the top center, and the rack is detachably slidably connected to the drive frame.

[0012] Furthermore, a sliding groove is provided on the outside of the drive frame, and a baffle is provided on the outside of the drive frame by bolts to cover the sliding groove. The rack slides with the drive frame through the sliding groove and is detached through the baffle.

[0013] Furthermore, the vertical drive component includes a second drive motor fixed to the outside of the drive frame, and a second drive tooth that meshes with a rack is fixedly mounted on the outside of the external output shaft of the second drive motor.

[0014] This utility model provides a fine coal sedimentation filtration centrifugal dewatering machine. By setting up a centrifugal dewatering cylinder, under normal conditions, the liquid to be separated can be directly poured into the centrifugal dewatering cylinder. After passing through the base ring filter, the liquid is discharged through the drain hole at the centrifugal dewatering cylinder. Due to the influence of water flow, the internal solids can converge to the outside during the sedimentation process, thus effectively ensuring the subsequent solids spreading effect. After the liquid stops flowing out rapidly, the centrifugal drive component starts to rotate the centrifugal dewatering cylinder to begin centrifugation. At the same time, the vertical drive component starts to move the spreading frame upwards. During the movement of the spreading frame, the solids begin to spread along its surface towards the inner wall of the centrifugal dewatering cylinder. Under the centrifugal force of its rotation, they are squeezed and adsorbed until the spreading frame has completely spread the solids. At this point, the solids are evenly spread on the inner wall of the centrifugal dewatering cylinder. Under the centrifugal force of rotation, they can effectively pass through the separation hole to complete the dewatering operation. Throughout the process, the uniformity of the solids spreading is ensured, effectively improving the dewatering efficiency. It has the advantage of effectively shortening the liquid penetration path through the spreading method to improve dewatering efficiency. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a fine coal sedimentation and filtration centrifugal dewatering machine, including a drainage sleeve 1. The inner wall of the drainage sleeve 1 is rotatably provided with a centrifugal dewatering cylinder 2 with a drainage hole on the inner bottom wall and a separation hole on the inner wall. A drive frame 3 extending above the centrifugal dewatering cylinder 2 is fixedly installed on the outside of the drainage sleeve 1. A centrifugal drive component 4 for driving the centrifugal dewatering cylinder 2 to rotate is fixedly installed inside the drive frame 3. A laying base ring 5 that blocks the drainage hole and has a filtering function is placed on the inner wall of the centrifugal dewatering cylinder 2. A laying frame 6 extending to the outside of the centrifugal dewatering cylinder 2 and connected to the drive frame 3 is movably arranged inside the laying base ring 5. A vertical drive component 7 for driving the laying frame 6 to move up and down is fixedly installed on the outside of the drive frame 3. The inner bottom wall of the drainage sleeve 1 is funnel-shaped and the end is connected to a drainage valve 8.

[0021] In this embodiment, the inner bottom wall of the drain sleeve 1 is provided with a support platform, the top of the support platform is provided with a ball bearing that contacts the bottom wall of the centrifugal dewatering cylinder 2, and the inner wall of the drain sleeve 1 is fixedly provided with a bearing that supports the side wall of the centrifugal dewatering cylinder 2.

[0022] By using a support platform in conjunction with ball bearings, the bottom of the centrifugal dewatering cylinder 2 can be effectively supported. At the same time, under the action of the bearings, lateral support can be achieved, ensuring that it remains stable during rotation.

[0023] In this embodiment, the centrifugal drive component 4 includes a first drive motor 41 fixed inside the drive frame 3, a first drive tooth 42 fixedly disposed on the outside of the output end of the first drive motor 41, and a toothed ring 43 that meshes with the first drive tooth 42 fixedly disposed on the outside of the centrifugal dehydration cylinder 2.

[0024] When the centrifugal drive unit 4 is working, it can directly drive the first drive tooth 42 to rotate through the first drive motor 41, so that the meshing tooth ring 43 can drive the centrifugal dehydration cylinder 2 to rotate, so as to achieve the basic centrifugal separation effect.

[0025] In this embodiment, the laying frame 6 is composed of a laying cone 61 and a rack 62 fixed at the center of its top. The rack 62 is detachably slidably connected to the drive frame 3.

[0026] The laying frame 6 with the above configuration can be effectively driven up and down by the rack 62, and the tapered configuration of the laying cone 61 can effectively lay solid objects.

[0027] In this embodiment, a sliding groove is provided on the outside of the drive frame 3, and a baffle is provided on the outside of the drive frame 3 by bolts to cover the sliding groove. The rack 62 slides with the drive frame 3 through the sliding groove and is disassembled through the baffle.

[0028] The drive frame 3 with the above configuration can be separated from the rack 62 by removing the baffle, which makes it easier to remove the laying frame 6 and thus makes maintenance operations more convenient. At the same time, the sliding groove combined with the baffle provides a restriction for the rack 62, so that it can only slide along the sliding groove in the driving state.

[0029] In this embodiment, the vertical drive component 7 includes a second drive motor 71 fixed to the outside of the drive frame 3, and a second drive tooth 72 that meshes with the rack 62 is fixedly installed on the outside of the external output shaft of the second drive motor 71.

[0030] When the vertical drive component 7 is in operation, it can directly drive the second drive tooth 72 to rotate through the second drive motor 71, thereby causing the rack 62 that meshes with it to start moving up and down, thus ensuring the effective progress of the laying process.
