Description

Technical Field

[0001] This invention relates to the field of gasification furnace equipment technology, and specifically to a slag hopper structure that can reduce the water content of gasification slag. Background Technology

[0002] With the large-scale promotion of coal gasification technology, the amount of coal gasification slag stockpiled and generated is increasing, causing serious environmental pollution and waste of land resources, which has an adverse impact on the sustainable development of coal chemical enterprises. The treatment of coal gasification slag is imminent.

[0003] Coal gasification slag is mainly composed of silicon dioxide, aluminum oxide, calcium oxide, ferric oxide and carbon. The residual carbon content of fine gasification slag is higher than that of coarse gasification slag. The main mineral phase of coal gasification slag is amorphous aluminum silicate, mixed with crystalline phases such as quartz and calcite. The chemical composition characteristics and special mineral phase composition of coal gasification slag, which are rich in silicon, aluminum and carbon resources, are the basis for the recycling and utilization of coal gasification slag.

[0004] However, in existing technologies, the water content of gasification slag is generally higher than 35%, which seriously restricts the efficiency of secondary utilization of gasification slag. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a slag hopper structure that can reduce the water content of gasification slag.

[0006] The technical solution of the present invention is as follows: a slag hopper structure that can reduce the water content of gasification slag, comprising a slag hopper body with a partition at its internal center, a conversion material plate movably disposed inside the slag hopper body and whose end abuts against the top of the partition, a first dewatering component disposed inside the slag hopper body, and a discharge screen plate disposed at the lower end of the slag hopper body; the interior of the slag hopper body is divided into a first cavity and a second cavity by the partition; both the lower ends of the first cavity and the second cavity are provided with discharge ports.

[0007] One end of the conversion plate is rotatably clamped to the slag hopper body via a rotating shaft. One end of the rotating shaft passes through the slag hopper body and is equipped with a conversion gear. A conversion motor is installed on the side wall of the slag hopper body through a motor housing. The output shaft of the conversion motor passes through the motor housing and is equipped with a small gear that meshes with the conversion gear.

[0008] There are two first dewatering components, which are respectively installed at the upper openings of the first and second chambers. Each first dewatering component includes a connecting frame, several dewatering rollers equidistantly distributed inside the connecting frame, and a dewatering motor installed on the side wall of the slag hopper body to provide power to the dewatering rollers. Each dewatering roller is rotatably engaged with the connecting frame via a connecting shaft. Both ends of each connecting shaft pass through the connecting frame and the slag hopper body, and each connecting shaft has a meshing connecting gear at the same end. The output shaft of the dewatering motor is fixedly connected to one of the connecting shafts.

[0009] There are two unloading screens, which are respectively installed at the lower end of the two discharge ports through mounting bases. The two unloading screens are movably connected to the mounting bases at the corresponding positions, and the bottom surface of both unloading screens is provided with a water receiving tray.

[0010] Furthermore, both the upper and lower ends of the conversion plate are slidably engaged with vibrating plates, and reset springs are provided at the connection points between the two vibrating plates and the conversion plate. Inside the conversion plate, a first vibrating motor is provided, with the two vibrating plates respectively abutting against one end of each vibrating plate.

[0011] Note: By installing a vibrating plate on the conversion feed plate, the smoothness of the gasification slag falling on the conversion feed plate is improved, while avoiding the gasification slag from sticking to the surface of the conversion feed plate and affecting the feeding efficiency.

[0012] Furthermore, the connecting shaft is hollow inside, and the dewatering roller is equipped with a capillary tube that communicates with the inside of the connecting shaft;

[0013] Explanation: By setting capillary tubes on the dewatering pressure roller, the water in the gasification slag enters the connecting shaft through the capillary tubes and is discharged from the slag hopper body during the process of the dewatering pressure roller squeezing the gasification slag, which helps to reduce the moisture content of the gasification slag.

[0014] Furthermore, the outer wall of the dewatering roller is provided with an extrusion groove;

[0015] Explanation: By setting extrusion grooves on the dewatering rollers, the gasified slag falling onto the dewatering rollers can be quickly squeezed between two adjacent dewatering rollers.

[0016] Furthermore, the mounting base is movably engaged with the discharge port, and a pressure sensor is installed at the connection between the mounting base and the discharge port. A PLC controller electrically connected to the pressure sensor is installed on the side wall of the slag hopper body.

[0017] Explanation: When the gasified slag accumulates to a certain height inside the first or second chamber, the mounting base contacts the pressure sensor under the pressure of the gasified slag, thereby starting the motor through the controller to switch the material plate, thus realizing the switching of the feeding area, which helps to improve the continuity of gasified slag processing.

[0018] Furthermore, each of the two mounting bases is equipped with a push screw that is threadedly connected to the discharge screen plate at the corresponding position. The ends of the two push screws pass through the mounting base at the corresponding position and are equipped with mating gears. The lower end of the side wall of the slag hopper body is slidably connected to the discharge motor via a sliding seat. The output shaft of the discharge motor is equipped with a drive gear that can mesh with the mating gear. An electric push rod connected to the discharge motor is installed inside the sliding seat.

[0019] Explanation: When the gasified slag inside the first or second chamber needs to be discharged, the electric push rod drives the unloading motor to move inside the mounting base, so that the drive gear meshes with the corresponding gear. This causes the push screw at the corresponding position to drive the unloading screen plate to move on the mounting base and open the discharge port, thereby reducing the workload of manual operation and improving the reliability of slag hopper body during discharge.

[0020] Furthermore, both the first and second chambers are movably connected to dewatering plates, and the side wall of the slag hopper body is equipped with electric cylinders that provide power to the two dewatering plates respectively.

[0021] Explanation: An electric cylinder is used to move the dewatering plate inside the first or second chamber to perform secondary compression and dewatering on the gasification slag, further reducing the moisture content of the gasification slag.

[0022] Furthermore, both the first and second cavities are equipped with positioning guide rods that slide and engage with the dehydration plates at corresponding positions;

[0023] Note: Setting a positioning guide rod helps improve the stability of the dehydration plate when it moves inside the first or second cavity.

[0024] Furthermore, a second vibration motor is installed at the connection between the electric cylinder and the dehydration plate;

[0025] Note: By setting a second vibration motor, the problem of compacted gasification slag accumulating inside the slag hopper body and causing difficulty in material discharge can be avoided.

[0026] Furthermore, a guide trough is provided on the vibrating plate;

[0027] Note: By setting a guide chute on the vibrating plate, the smoothness of the gasification slag falling on the conversion plate is improved, thus increasing work efficiency.

[0028] The method of using this invention includes the following steps:

[0029] S1. Connect the converter motor and the dehydration motor to the external power supply respectively;

[0030] S2. The small gear on the conversion motor drives the conversion gear to rotate, thereby causing the conversion plate to deflect at a certain angle and block the opening at the upper end of the first cavity.

[0031] S3. The gasification slag is introduced into the slag hopper body through the slag remover, and the gasification slag enters the second chamber under the action of the conversion plate.

[0032] S4. Start the dewatering motor corresponding to the second chamber. The dewatering motor drives each dewatering roller to rotate and squeeze the gasification slag for dewatering. The water at the squeezing point enters the water receiving tray through the discharge screen. The squeezed gasification slag falls onto the discharge screen at the bottom of the second chamber.

[0033] S5. When the material inside the second chamber is full, the discharge screen plate corresponding to the second chamber is pulled out for discharge; then the conversion motor is used to drive the conversion plate to deflect at a certain angle and block the opening at the upper end of the second chamber; under the action of the gasification slag conversion plate, it enters the first chamber.

[0034] S6. Repeat steps S2-S5 to continuously separate the moisture in the gasification residue.

[0035] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0036] First, the present invention has a reasonable structural design. By setting two cavities inside the slag hopper body and circulating feed inside the two cavities, the residence time of the gasification slag inside the slag hopper body is extended, thereby effectively reducing the moisture content of the gasification slag.

[0037] Secondly, by setting a first dewatering component and a dewatering plate inside the slag hopper body, the present invention performs extrusion dewatering treatment on the gasification slag entering the two chambers respectively, thereby further reducing the moisture content of the gasification slag, effectively improving the utilization effect of the gasification slag and improving economic benefits.

[0038] Third, this invention utilizes a discharge motor to control the opening and closing of the discharge screen, and simultaneously sets up a pressure sensor between the discharge screen and the discharge port. The PLC controller is used to control the automated opening and closing of the discharge screen, which greatly reduces the workload of manual operation and improves work efficiency.
