Description

Technical Field

[0001] This utility model relates to the technical field of coal slime centrifuges, specifically to a scraper-mounted coal slime centrifuge. Background Technology

[0002] Coal slime centrifuges are key equipment in coal preparation plants for dewatering and separating coal slime. They utilize the principle of centrifugal force to achieve efficient separation of solid particles and liquids.

[0003] Existing horizontal coal slime centrifuges, such as Figure 1 The coal slime centrifuge shown has its large end facing outwards. Material enters the scraper's inner cavity through the feed cylinder and then into the cavity between the scraper and the screen basket. Under the centrifugal force generated by high-speed rotation, liquid enters the solid collection bin through the screen basket gaps and is discharged from the outlet. Solids are trapped on the inner surface of the screen basket and are forcibly discharged from the outlet of the solid-liquid collection bin by the scraper. However, the screen basket is a wear part and needs frequent replacement. In this type of coal slime centrifuge with a front-mounted scraper structure, replacing the screen basket requires first removing the scraper, then reinstalling it after the screen basket is replaced. This lengthy disassembly and reassembly process reduces the centrifuge's efficiency. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a scraper-mounted coal slime centrifuge to solve the technical problem that in the existing horizontal coal slime centrifuge, the scraper must be removed first when replacing the screen basket, and then the scraper must be reinstalled after the screen basket is replaced, which takes a long time and thus affects the working efficiency of the coal slime centrifuge.

[0005] According to the technical solution provided in the embodiments of this application, a scraper-type reverse-loading coal slime centrifuge includes a centrifuge body;

[0006] The sieve basket is detachably connected to the sieve basket bracket, with the large end of the sieve basket facing the differential.

[0007] The scraper, with its large end facing the differential, is mounted on the central spindle of the differential via splines and bolts, and is located inside the screen basket.

[0008] Furthermore, the sieve basket bracket is fastened to the outer bushing of the differential by bolts.

[0009] Furthermore, the sieve basket is installed inside the solid-liquid collection chamber, and the diameter of the solid-liquid collection chamber is larger than that of the sieve basket.

[0010] Furthermore, the solid-liquid collection chamber is separated into a liquid collection chamber and a solid collection chamber by a partition, for the separate discharge of the separated liquid and solid.

[0011] Furthermore, the differential is mounted in the differential housing via bearings, and its tail end is fixedly connected to the output end of the pulley.

[0012] Furthermore, the differential housing and the solid-liquid collection chamber are connected as one unit by bolts.

[0013] Furthermore, the differential housing is bolted to the elastic base.

[0014] Furthermore, the door body is connected to the solid-liquid collection chamber by a hinge, while the feed cylinder is bolted to the door body as a whole.

[0015] In summary, the beneficial effects of this application are as follows: by changing the orientation of the screen basket in the solid-liquid collection chamber of the coal slime centrifuge from having the large end facing the door to having the large end facing the differential, and by installing the scraper inside the screen basket, when the screen basket needs to be replaced due to wear, only the screen basket needs to be removed, without first removing the scraper, which makes the screen basket replacement very convenient, thereby reducing disassembly and assembly time. Not only is the screen basket easy to install, but it also saves time and effort, thereby improving the working efficiency of the coal slime centrifuge. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] A scraper-type reverse-loading coal slime centrifuge, its structure is as follows: Figure 2As shown, the centrifuge includes a centrifuge body. A differential 7 on the centrifuge body is mounted in a differential housing 8 via bearings. The differential housing 8 and the solid-liquid collection chamber 6 are bolted together. A pulley 9 is mounted on one end of the differential 7. The pulley 9 is connected to a motor via a transmission belt so that the motor drives the pulley 9 to rotate after starting, thereby making the differential 7 rotate synchronously. At the other end of the differential 7, a sieve basket bracket 5 is bolted to the outer bushing of the differential 7. The bolts connect the sieve basket 3 to the sieve basket bracket 5. A scraper 4 is mounted on the central shaft of the differential 7 via splines and bolts, so that the sieve basket 3 and the scraper 4 rotate at high speeds at different speeds and form a fixed differential ratio.

[0023] like Figure 2 As shown, the screen basket 3 has a conical structure, with the large end of the screen basket 3 facing the differential 7, while the scraper 4 is installed inside the screen basket 3, with its large end also facing the differential 7, so that the screen basket 3 and the scraper 4 are installed in reverse inside the coal slime centrifuge body. Therefore, when disassembling the screen basket 3, it is not necessary to remove the scraper 4 first, and the screen basket 3 can be disassembled and assembled directly.

[0024] like Figure 2 As shown, the sieve basket 3 is installed inside the solid-liquid collection chamber 6, and the diameter of the solid-liquid collection chamber 6 is larger than that of the sieve basket 3. The solid-liquid collection chamber 6 is separated into a liquid collection chamber and a solid collection chamber by a partition, so that the bottom of the liquid collection chamber is connected to the drain pipe, and the solid collection chamber is connected to the discharge pipe for the separation and discharge of the liquid and solid.

[0025] like Figure 2 As shown, the door body 2 is connected to the solid-liquid collection chamber 6 by a hinge, while the feed cylinder 1 is bolted to the door body 2 to allow the material to enter the solid-liquid collection chamber 6 from the feed cylinder 1, and then the coal slime is separated into solid and liquid in the solid-liquid collection chamber 6. The differential housing 8 is bolted to the elastic base 10 so that the elastic base 10 provides elastic support for the coal slime centrifuge body during the separation process and reduces the vibration during the separation process.

[0026] The working principle of this utility model of a scraper-mounted reverse-loading coal slime centrifuge is as follows:

[0027] In the process of solid-liquid separation of coal slime in a coal slime centrifuge with screen basket 3 and scraper 4 installed in reverse, the motor drives the pulley 9 to rotate, thereby causing the differential 7 installed at the output end of the pulley 9 to rotate at high speed, so that the output end of the differential 7 outputs two different speeds, thereby causing the screen basket 3 and scraper 4 to rotate at high speeds at different speeds and forming a fixed differential ratio. The material enters the cavity between scraper 4 and screen basket 3 through the feed cylinder 1. Under the action of centrifugal force generated by high-speed rotation, the liquid enters the liquid collection chamber on the solid-liquid collection bin 6 through the gap of the screen basket 3 and is discharged from the drain pipe, while the solid is trapped on the inner surface of the screen basket 3. During the rotation of the scraper 4, the solid is discharged from the large end of the screen basket 3 and enters the solid collection chamber of the solid-liquid collection bin 6 and is discharged from the discharge pipe. By modifying the screen basket 3 inside the solid-liquid collection chamber 6 of the coal slime centrifuge from facing the door 2 to facing the differential 7, and installing the scraper 4 inside the screen basket 3, when the screen basket 3 needs to be replaced due to wear, only the screen basket 3 needs to be removed, without first removing the scraper 4, which can be very convenient to replace the screen basket 3, thereby reducing disassembly and assembly time. Not only is the installation of the screen basket 3 convenient, but it also saves time and effort, thereby improving the working efficiency of the coal slime centrifuge.

[0028] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
