Abstract
Description
Technical Field
[0001] This utility model relates to an anti-clogging pipeline device for a coal-water slurry preparation system, belonging to the field of coal-water slurry technology. Background Technology
[0002] Coal-water slurry can be used as fuel for furnaces or as a feedstock for syngas, offering advantages such as stable combustion and low pollution emissions. It is a mixture of coal, water, and chemical additives formulated according to specific requirements. It possesses good fluidity and stability, is easy to store, and can be atomized for combustion. It is a relatively inexpensive and clean fuel with high combustion efficiency and low pollution, and can replace heavy oil to alleviate energy security issues related to oil shortages. Coal-water slurry is a low-pollution, high-efficiency, pipeline-transportable coal-based fluid fuel obtained through physical processing of approximately 65% coal, 34% water, and 1% additives. It changes the traditional combustion method of coal, demonstrating significant environmental and energy-saving advantages. Especially in recent years, with the adoption of waste resource utilization technologies, the successfully developed environmentally friendly coal-water slurry can significantly improve its environmental benefits without increasing costs.
[0003] However, in existing technologies, after the coal-water slurry is prepared and needs to be transported, some of the slurry will stick to the inside of the pipeline. Over a long period of use, this will affect the transportation of the coal-water slurry and reduce the production of the slurry, resulting in the loss of some of the slurry. There is an urgent need for an anti-clogging pipeline device for the coal-water slurry preparation system to solve the above-mentioned problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an anti-clogging pipe device for a coal-water slurry preparation system, thereby solving the problems mentioned in the background. This invention is highly practical. By using a dual-head motor to drive the conveying slurry, the coal-water slurry can be moved while the scraping slurry can scrape off the coal-water slurry inside the anti-clogging pipe, preventing the coal-water slurry from adhering to the anti-clogging pipe and ensuring that the discharge of the coal-water slurry is not affected.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an anti-clogging pipeline device for a coal-water slurry preparation system, comprising a coal-water slurry anti-clogging pipeline, a protective shell fixedly connected inside the coal-water slurry anti-clogging pipeline, a double-headed motor fixedly connected inside the protective shell, a rotating rod fixedly connected to the output end on the left side of the double-headed motor, and a conveying slurry fixedly connected to the circumferential surface of the rotating rod;
[0006] The output end of the right end of the dual-head motor is fixedly connected to a docking rod. The right end of the docking rod is fixedly connected to a fixing plate by screws. Two connecting rods are fixedly connected to the circumferential surface of the fixing plate. Slurry scrapers are fixedly connected to the surfaces of the two connecting rods. A filter screen is fixedly connected to the right end of the coal-water slurry anti-clogging pipe.
[0007] Furthermore, a sleeve is fixedly connected to the circumferential surface of the coal-water slurry anti-clogging pipe, and two mounting rings are fixedly connected to the circumferential surface of the sleeve, and two mounting bases are fixedly connected to the circumferential surfaces of the two mounting rings.
[0008] Furthermore, two docking rings are fixedly connected to both ends of the water-coal slurry anti-clogging pipeline, and multiple mounting blocks are fixedly connected to the circumferential surfaces of the two docking rings.
[0009] Furthermore, the surfaces of the two scraper slurries are provided with a rubber layer, and the two scraper slurries are in contact with the filter screen.
[0010] Furthermore, both of the protective housings and connecting rods are made of metal.
[0011] Furthermore, both of the mating rings have a rubber layer on their surfaces.
[0012] The beneficial effects of this utility model are as follows: This utility model provides an anti-clogging pipe device for a coal-water slurry preparation system. Because this utility model incorporates a filter screen, a scraper, a dual-head motor, a protective shell, a conveying slurry, a rotating rod, a fixed disc, a connecting rod, and a connecting rod, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The dual-head motor drives the conveying slurry, which moves the coal-water slurry, while the scraper removes the coal-water slurry from inside the anti-clogging pipe, preventing the slurry from adhering to the pipe and thus not affecting the discharge of the coal-water slurry.

Detailed Implementation
[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figures 1-5 This utility model provides a technical solution: an anti-clogging pipe device for a coal-water slurry preparation system, comprising a coal-water slurry anti-clogging pipe 1, a protective shell 7 fixedly connected inside the coal-water slurry anti-clogging pipe 1, a double-headed motor 6 fixedly connected inside the protective shell 7, a rotating rod 11 fixedly connected to the output end on the left side of the double-headed motor 6, a conveying slurry 10 fixedly connected to the circumferential surface of the rotating rod 11, a connecting rod 15 fixedly connected to the output end on the right side of the double-headed motor 6, a fixed plate 14 fixedly connected to the right end of the connecting rod 15 by screws, two connecting rods 13 fixedly connected to the circumferential surface of the fixed plate 14, scraping slurry 8 fixedly connected to the surface of both connecting rods 13, and a filter screen 9 fixedly connected to the right end of the coal-water slurry anti-clogging pipe 1. This design solves the problem that in the original device, after the coal-water slurry is prepared and needs to be transported, some coal-water slurry will stick inside the pipe, which will affect the transportation of coal-water slurry and reduce the production of coal-water slurry, resulting in the loss of some coal-water slurry during long-term use.
[0022] As the first embodiment of this utility model: a sleeve 12 is fixedly connected to the circumferential surface of the coal-water slurry anti-blocking pipe 1. Two mounting rings 2 are fixedly connected to the circumferential surface of the sleeve 12. Two mounting bases 3 are fixedly connected to the circumferential surface of the two mounting rings 2. The mounting rings 2 installed on the surface of the sleeve 12 can be used to install and support the coal-water slurry anti-blocking pipe 1. It is installed on the bracket by the mounting bases 3. The left and right ends of the coal-water slurry anti-blocking pipe 1 can be connected to an external coal-water slurry pipe. When the coal-water slurry anti-blocking pipe 1 is blocked, the double-head motor 6 can be run to drive the scraper 8 to scrape off the coal-water slurry inside the coal-water slurry anti-blocking pipe 1. Two connecting rings 4 are fixedly connected to both ends of the coal-water slurry anti-clogging pipe 1. Multiple mounting blocks 5 are fixedly connected to the circumferential surface of each connecting ring 4. The connecting rings 4, installed on the surface of the coal-water slurry anti-clogging pipe 1, can be connected to an external pipe via bolts. After the external pipe supplies coal-water slurry into the coal-water slurry anti-clogging pipe 1, the dual-head motor 6 drives the scraper 8 to scrape away the coal-water slurry inside the coal-water slurry anti-clogging pipe 1, preventing the coal-water slurry from adhering to the inside of the pipe 1. The surfaces of the two scraper 8 are covered with a rubber layer, and the two scraper 8 adhere to the filter screen 9. The rubber layer on the surface of the scraper 8 protects the inner wall of the coal-water slurry anti-clogging pipe 1, reduces friction inside the pipe 1, and increases its service life. When the scraper 8 rotates, it scrapes away the coal-water slurry adhering to the surface of the filter screen 9, preventing the coal-water slurry on the surface of the filter screen 9 from hardening and clogging the filter screen 9. The two protective shells 7 and the connecting rod 13 are made of metal and can support the dual-head motor 6 and the scraper 8 inside the coal-water slurry anti-clogging pipe 1. The surfaces of the two mating rings 4 are provided with rubber layers, which can reduce the gap between the coal-water slurry anti-clogging pipe 1 and the external pipe, and prevent leakage when the coal-water slurry anti-clogging pipe 1 is transporting coal-water slurry.
[0023] As a second embodiment of this utility model: First, the connecting rings 4 at both ends of the coal-water slurry anti-blocking pipe 1 are connected to the external pipes respectively. When coal-water slurry is transported through the coal-water slurry anti-blocking pipe 1 via the external pipes, the dual-head motor 6 can be run to drive the conveying slurry 10 to rotate, so that the coal-water slurry is discharged through the spiral structure of the conveying slurry 10. At the same time, the scraper slurry 8 scrapes off the coal-water slurry inside the coal-water slurry anti-blocking pipe 1, which can effectively reduce the situation of coal-water slurry adhering to the inside of the coal-water slurry anti-blocking pipe 1.
