Description

Technical Field

[0001] The utility model relates to the technical field of clean coal processing, in particular to a coarse particle clean coal dehydration and ash reduction device. Background Art

[0002] In the process of coal processing, it is often necessary to use a coarse-particle clean coal dehydration and ash reduction device, namely a centrifuge, to centrifugally dehydrate the clean coal. During the dehydration process, not only can the moisture in the clean coal be reduced, but also high-ash fine mud can be removed and the ash content of the clean coal can be reduced.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing coarse-particle clean coal dehydration and ash-removing devices mostly use a tubular discharge port to discharge materials, which requires stopping the machine to wait for the discharge of the batch of clean coal. The discharge takes too much time, which affects the clean coal processing efficiency and urgently needs to be improved. Therefore, we propose a coarse-particle clean coal dehydration and ash-removing device. Utility Model Content

[0004] The utility model aims to provide a coarse particle clean coal dehydration and ash reduction device, which solves the problems raised in the background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a coarse particle clean coal dehydration and ash reduction device, comprising a frame, a bottom plate is placed inside the frame, a push rod motor is fixedly installed on the upper surface of the frame, and a centrifugal cylinder is placed outside the bottom plate;

[0006] The bottom of the frame is fixedly connected to a support platform through a bracket, a driving motor is fixedly installed in the middle of the lower surface of the support platform, and the top of the transmission shaft of the driving motor is fixedly connected to the bottom plate;

[0007] A support rod is fixedly installed on the middle part of the upper surface of the bottom plate, a cross bar is fixedly installed on the top of the support rod, and both ends of the cross bar are fixedly connected to the inner wall of the annular plate;

[0008] A gantry is placed at the bottom of the transmission shaft of the push rod motor, and the transmission shaft is rotatably connected to the gantry through a bearing;

[0009] T-blocks are installed at the bottom of both sides of the gantry, and the gantry is connected to the centrifugal cylinder through the T-blocks, and can be used in combination with components such as the centrifugal cylinder, the bottom plate and the annular plate. During the use of the coarse-grained clean coal dehydration and ash-reducing device, whenever a single batch of clean coal is discharged, the gantry can be driven to move up by the transmission shaft of the push rod motor, and the gantry drives the centrifugal cylinder to move up, so that a large amount of clean coal slides through the support platform, and then the centrifugal cylinder is moved down to reset, coal is added, and then the scattered coal is processed. Compared with the existing unloading method, the efficiency problem caused by waiting for unloading can be avoided. At the same time, during the upward movement of the centrifugal cylinder, the coal adhered to the inner wall of the centrifugal cylinder can be scraped off by the annular plate, and there is no need for an independent cleaning process for the adhered coal, which is highly practical.

[0010] As an optional solution to the technical solution of the present application, the outer end of the T-block is connected to the gantry through a tension spring, and the inner end of the T-block extends into a preset groove on the outer wall of the centrifugal barrel. It can be used in conjunction with components such as the T-block and the tension spring. The tension spring can be used to apply a force to the T-block so that it is stuck in the groove. Conversely, the T-block can be moved outward to cancel the limit of the centrifugal barrel. The centrifugal barrel can be assembled detachably, which is convenient for later maintenance and replacement of the barrel or internal components, and meets the use requirements.

[0011] As an optional solution of the technical solution of the present application, reinforcing ribs are fixedly installed at the two corners in the frame, and the reinforcing ribs are of a triangular structure. The reinforcing ribs can be used to increase the connection stiffness to prevent tearing and breakage, thereby improving the processing safety factor.

[0012] As an optional solution of the technical solution of the present application, an indicator sign is fixedly installed in the middle of the outer wall of the frame, and guiding text is printed on the indicator sign. The text on the indicator sign can inform the method of material unloading operation and the method of scraping coal from the inner wall, which is convenient for different operators to understand and use.

[0013] As an optional solution of the technical solution of the present application, an inclined portion is provided on the outer side of the upper surface of the support platform close to the driving motor, and there are four groups of inclined portions. With the arrangement of multiple groups of inclined portions, most clean coal blocks can slide down through the inclined portions, thereby reducing the burden of manual cleaning of the support platform.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model discloses a coarse-particle clean coal dehydration and ash-reducing device, which is provided with a centrifugal cylinder, a bottom plate and an annular plate.

Compared with the existing unloading method, the efficiency problem caused by waiting for unloading can be avoided. At the same time, during the upward movement of the centrifugal cylinder, the coal adhered to the inner wall of the centrifugal cylinder can be scraped off by the annular plate, and there is no need for an independent cleaning process of the adhered coal, which has strong practicality.

[0016] 2. The utility model is a coarse-particle clean coal dehydration and ash-reducing device, which is provided with a T-block and a tension spring. The tension spring can give a force to the T-block to make it stuck in the slot. Conversely, the T-block can be moved outward to cancel the limit of the centrifugal cylinder. The centrifugal cylinder can be detachably assembled, which is convenient for later maintenance and replacement of the cylinder body or internal components, and meets the use requirements.
