Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology for the comprehensive utilization of coal gangue and coal slime, specifically, to a solid waste treatment machine for the comprehensive utilization of coal gangue and coal slime. Background Technology

[0002] Coal gangue is a solid waste discharged during the coal mining and washing process. It is a blackish-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. Coal gangue also contains a large number of impurities and harmful substances, such as sulfur, dust, and heavy metals.

[0003] Due to its low combustibility and high content of harmful substances, coal gangue is difficult to process. The main method for coal gangue disposal is landfill, which involves burying large amounts of coal gangue underground. However, there are many restrictions on the selection of landfill sites. They must be located in areas with low-lying terrain, deep groundwater levels, and thick soil layers to minimize the impact on the surrounding environment. However, my country has accumulated 1,000 tons of coal gangue over the years, and continues to produce about 100 tons annually. In the long run, landfilling not only provides a temporary solution but also reduces a significant amount of land use area. Summary of the Invention

[0004] This invention proposes a solid waste treatment machine for the comprehensive utilization of coal gangue and coal slime, which solves the problem of reducing a large amount of land use area by treating coal gangue through landfill in the existing technology.

[0005] The technical solution of the present invention is as follows:

[0006] A solid waste treatment machine for the comprehensive utilization of coal gangue and coal slime includes a combustion chamber and a support column, and further includes an igniter, an isolation cylinder, a water-vapor heat exchange component, a separation and storage component, a baffle plate component, and an air intake and exhaust component. The igniter is disposed on the combustion chamber, the isolation cylinder is disposed inside the combustion chamber and has multiple through holes, the water-vapor heat exchange component is disposed outside the combustion chamber and on the support column, and is used to heat water into steam using the heat released from the combustion of coal gangue and coal slime, the separation and storage component is disposed on the support column and located directly below the combustion chamber, and is used to separately store the products after the combustion of coal gangue and coal slime, the baffle plate component is disposed on the support column and located between the combustion chamber and the separation and storage component, and is used to switch the connection between the combustion chamber and the separation and storage component, the air intake and exhaust component is disposed on the support column and is fixedly connected to the combustion chamber, and is used for the intake and exhaust of coal gangue and coal slime during the combustion process.

[0007] The water vapor heat exchange component includes:

[0008] A heating chamber is disposed outside the combustion chamber and is mounted on the support column;

[0009] A water inlet pipe is fixedly connected to the heating chamber, and a first electric valve is installed on the water inlet pipe;

[0010] The exhaust pipe is fixedly connected to the heating chamber, and a second electric valve is installed on the exhaust pipe.

[0011] The distributed storage component includes:

[0012] The outer cylinder is mounted on the support column.

[0013] An inner cylinder, which is disposed inside the outer cylinder;

[0014] A first storage chamber, which is detachably mounted on the outer cylinder;

[0015] The second storage chamber is detachably mounted on the inner cylinder.

[0016] The insert assembly includes:

[0017] A fixing frame is mounted on the support column, and a sliding groove is provided on the fixing frame;

[0018] An electric scissor lift, wherein the electric scissor lift is mounted on the fixed frame;

[0019] A baffle is mounted on the electric scissor lift.

[0020] The intake and exhaust assembly includes:

[0021] The blower is mounted on the support column;

[0022] A connecting pipe, which is fixedly connected to the blower and the combustion chamber;

[0023] An exhaust pipe is fixedly connected to the combustion chamber.

[0024] The combustion chamber is further provided with:

[0025] A first feed pipe is fixedly connected to the combustion chamber;

[0026] The second feed pipe is fixedly connected to the combustion chamber, and the outlet end of the second feed pipe is located directly above the isolation cylinder.

[0027] The working principle and beneficial effects of this invention are as follows:

[0028] 1. In this invention, coal slime and coal gangue are injected into the combustion chamber and the isolation cylinder respectively through the first feed pipe and the second feed pipe. Then, the first electric valve is opened, and water is injected into the heating chamber through the water inlet pipe. Then, the coal slime is ignited by the igniter. At the same time, the blower is started to blow air into the combustion chamber to assist combustion. The ignited coal slime heats the coal gangue through multiple through holes in the isolation cylinder to make it burn. The heat released by the combustion of coal slime and coal gangue turns the water in the heating chamber into steam. Finally, the second electric valve is opened, and the steam is discharged from the heating chamber through the steam outlet pipe. The steam can be used for heating or power generation.

[0029] 2. In this invention, after the coal slime and coal gangue have been burned, the electric scissor lift is activated. The electric scissor lift moves the baffle away from the combustion chamber. The coal slime and coal gangue after combustion fall into the first storage chamber and the second storage chamber respectively through the outer cylinder and the inner cylinder. The coal ash after the coal slime is burned can be used as building materials, waste, sewage treatment or road construction, etc. The coal gangue after combustion can be used as an active admixture for cement, or it can be directly mixed with lime and gypsum in an appropriate ratio to grind into clinker-free cement for use.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 6 As shown, a solid waste treatment machine for the comprehensive utilization of coal gangue and coal slime includes a combustion chamber 1 and a support column 2. It also includes an igniter 3, an isolation cylinder 4, a water-steam heat exchange component, a storage component, a baffle plate assembly, and an air intake and exhaust component. The igniter 3 is mounted on the combustion chamber 1. The isolation cylinder 4 is located inside the combustion chamber 1 and has multiple through holes. The water-steam heat exchange component is located outside the combustion chamber 1 and on the support column 2, used to heat water into steam using the heat released from the combustion of coal gangue and coal slime. The storage component is mounted on the support column 2 and located directly below the combustion chamber 1, used to separately store the products after the combustion of coal gangue and coal slime. The baffle plate assembly is mounted on the support column 2 and located between the combustion chamber 1 and the storage component, used to switch the connection between the combustion chamber 1 and the storage component. The air intake and exhaust component is mounted on the support column 2 and is fixedly connected to the combustion chamber 1, used for the intake and exhaust of coal gangue and coal slime during the combustion process.

[0040] The water-steam heat exchange assembly includes a heating chamber 5, a water inlet pipe 6, and a steam outlet pipe 8. The heating chamber 5 is located outside the combustion chamber 1 and is mounted on the support column 2. The water inlet pipe 6 is fixedly connected to the heating chamber 5 and is equipped with a first electric valve 7. The exhaust pipe 19 is fixedly connected to the heating chamber 5 and is equipped with a second electric valve 9 on the steam outlet pipe 8.

[0041] Open the first electric valve 7, and water flows into the heating chamber 5 through the water inlet pipe 6 for heating. After the water is heated into steam, open the second electric valve 9, and the steam is discharged from the heating chamber 5 through the steam outlet pipe 8. The discharged steam can be used for heating or power generation.

[0042] The separate storage component includes an outer cylinder 10, an inner cylinder 11, a first storage chamber 12, and a second storage chamber 13. The outer cylinder 10 is mounted on the support column 2, the inner cylinder 11 is mounted inside the outer cylinder 10, the first storage chamber 12 is detachably mounted on the outer cylinder 10, and the second storage chamber 13 is detachably mounted on the inner cylinder 11.

[0043] After combustion, the coal slurry falls through the outer cylinder 10 into the first storage chamber 12 for storage, and the coal gangue falls through the inner cylinder 11 into the second storage chamber 13 for storage. Finally, the coal gangue and coal slurry can be removed by simply removing the second storage chamber 13 and the first storage chamber 12 from the inner cylinder 11 and the outer cylinder 10.

[0044] Further points to add: Coal ash can be used as building materials, such as concrete, bricks, and gypsum board. Coal ash can increase the strength and durability of these materials while reducing costs. Coal ash concrete is more durable than ordinary concrete. Furthermore, coal ash contains many beneficial nutrients, such as potassium, calcium, magnesium, and trace elements, which can promote plant growth, thus making it suitable as a fertilizer. Elements such as iron, aluminum, and calcium in coal ash can adsorb organic matter and heavy metal ions in wastewater, thereby purifying the water and making it suitable as a wastewater treatment agent. Coal ash can also be used as a road construction material, increasing the strength and durability of roads while reducing costs. Finally, coal ash can be used in many industrial applications, such as glass manufacturing, ceramics manufacturing, and cement production.

[0045] Combustion-processed coal gangue has a certain degree of activity and can be used as an active admixture in cement production to produce ordinary Portland cement (with a content of less than 20%), pozzolanic cement (with a content of 20-50%), and low-clinker cement (with a content of more than 50%). It can also be directly mixed with lime and gypsum in appropriate proportions to produce clinker-free cement. It can be used as a binder, with fluidized bed slag as aggregate or with gravel and fluidized bed slag as coarse and fine aggregates to make concrete blocks or hollow concrete blocks and other building materials. Countries such as the United Kingdom and Belgium have factories that use coal gangue to replace siliceous raw materials in the production of cement.

[0046] The insert plate assembly includes a fixed frame 14, an electric scissor lift 15, and a baffle 16. The fixed frame 14 is mounted on the support column 2 and has a sliding groove. The electric scissor lift 15 is mounted on the fixed frame 14, and the baffle 16 is mounted on the electric scissor lift 15.

[0047] After the coal slime and coal gangue have burned, the electric scissor lift 15 is started. The electric scissor lift 15 drives the baffle 16 to move away from the combustion chamber 1, so that the burned coal slime and coal gangue fall into the outer cylinder 10 and the inner cylinder 11.

[0048] The intake and exhaust assembly includes a blower 17, a connecting pipe 18 and an exhaust pipe 19. The blower 17 is mounted on the support column 2. The connecting pipe 18 is fixedly connected to the blower 17 and the combustion chamber 1. The exhaust pipe 19 is fixedly connected to the combustion chamber 1.

[0049] After the coal slime is ignited, the blower 17 is started to blow air from the outside into the combustion chamber 1 to aid the combustion of the coal slime and coal gangue. The exhaust gas generated after combustion is discharged from the combustion chamber 1 through the exhaust pipe 19.

[0050] The combustion chamber 1 is also provided with a first feed pipe 20 and a second feed pipe 21. The first feed pipe 20 is fixedly connected to the combustion chamber 1, and the second feed pipe 21 is fixedly connected to the combustion chamber 1. The outlet end of the second feed pipe 21 is located directly above the isolation cylinder 4.

[0051] Coal slime and coal gangue are fed into the combustion chamber 1 and the isolation cylinder 4 respectively through the first feed pipe 20 and the second feed pipe 21, thus separating the two.

[0052] In summary, the working principle of this coal gangue and coal slime integrated utilization solid waste treatment machine is as follows: First, coal slime and coal gangue are added to the combustion chamber 1 and the isolation cylinder 4 respectively through the first feed pipe 20 and the second feed pipe 21. Then, the first electric valve 7 is opened, and water flows into the heating chamber 5 through the water inlet pipe 6.

[0053] Ignite 3 to ignite the coal slime. After the coal slime is ignited, start blower 17 to blow air from the outside into combustion chamber 1 to aid the combustion of coal slime and coal gangue. After the water is heated into steam, open the second electric valve 9. The steam is discharged from heating chamber 5 through steam outlet pipe 8. The discharged steam can be used for heating or power generation. The exhaust gas generated after combustion is discharged from combustion chamber 1 through exhaust pipe 19.

[0054] After the coal slime and coal gangue have burned, the electric scissor lift 15 is activated. The electric scissor lift 15 drives the baffle 16 to move away from the combustion chamber 1, so that the burned coal slime and coal gangue fall into the outer cylinder 10 and the inner cylinder 11. The burned coal slime falls into the first storage chamber 12 through the outer cylinder 10 and is stored thereafter. The burned coal gangue falls into the second storage chamber 13 through the inner cylinder 11 and is stored thereafter. Finally, the burned coal gangue and coal slime can be removed by simply removing the second storage chamber 13 and the first storage chamber 12 from the inner cylinder 11 and the outer cylinder 10.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
