Technical Field

[0001] This utility model relates to the field of coal-water slurry gasification technology, and in particular to a coal-water slurry gasification furnace feeding mechanism. Background Technology

[0002] The coal-water slurry gasifier, also known as the Texaco coal gasifier, is an industrial furnace that uses coal-water slurry as raw material for gasification. During the production process, a feeding mechanism is required to input the coal-water slurry into the gasifier for processing.

[0003] Existing technologies, such as Chinese Patent Publication No. CN220951678U, disclose a coal-water slurry gasifier suitable for coal-water slurry gasification, including a housing. An operation panel is fixedly installed on the front of the housing, with an indicator screen and operation buttons on the front of the operation panel. A heat insulation layer is fixedly installed on the inner wall of the housing, and a high-temperature sensor is fixedly installed on one side of the heat insulation layer. This invention facilitates the processing and gasification of coal-water slurry through the housing design; facilitates operation of the entire device through the operation panel; allows users to intuitively understand the temperature inside the housing and make timely adjustments; facilitates the processing of coal-water slurry in different areas through the operation buttons; facilitates temperature isolation and increases service life through the heat insulation layer; and facilitates the detection of layered temperatures inside the housing through the high-temperature sensor. However, this invention is not convenient for batching and adjusting the feed rate and speed of the coal-water slurry as needed during feeding.

[0004] To address the inconvenience of feeding coal-water slurry into gasifiers in batches as needed and adjusting the feed rate and speed, a feeding mechanism is required to input the coal-water slurry into the gasifier. However, the existing feeding mechanism is not convenient for inputting coal-water slurry in batches as needed, nor is it convenient for controlling the amount and speed of each input. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that it is inconvenient to feed the coal-water slurry gasifier in batches as needed and to adjust the feed amount and speed, and to propose a coal-water slurry gasifier feeding mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a feeding mechanism for a coal-water slurry gasifier, comprising a gasifier, a feeding box, an inlet pipe, an outlet pipe, and a feeding device. The feeding box is fixedly connected to the top surface of the gasifier, the inlet pipe is fixedly connected to the top surface of the gasifier, and the outlet pipe is fixedly connected to the side surface of the gasifier. The feeding device is disposed on the surface of the feeding box and includes a fixed shaft. The fixed shaft is fixedly connected to the inner wall of the feeding box, and a baffle plate is rotatably connected to the surface of the fixed shaft. An arc-shaped groove is formed on the surface of the feeding box, and a movable rod is slidably connected to the surface of the arc-shaped groove. A motor is fixedly installed on the surface of the feeding box, and a screw is fixedly connected to the output end of the motor. The screw is rotatably connected to the inner wall of the feeding box, and a movable platform is threadedly connected to the surface of the screw. A T-shaped groove is formed on the surface of the movable platform, and a T-shaped block is slidably connected to the surface of the T-shaped groove. The T-shaped block is fixedly connected to the surface of the movable rod.

[0007] Furthermore, the movable rod cooperates with the baffle plate, and the number of the fixed shaft, baffle plate, arc groove, movable rod, T-slot and T-block are all two sets and arranged symmetrically in pairs.

[0008] Furthermore, a pointer is fixedly connected to the end of the movable rod away from the T-block, and a scale groove is opened on the surface of the feed box, with the pointer cooperating with the scale groove.

[0009] Furthermore, the surface of the feed box is fixedly connected with guide columns, and there are two sets of guide columns arranged symmetrically. The movable table is slidably connected to the surface of the guide columns.

[0010] Furthermore, a filter device is provided on the surface of the feed box. The filter device includes a fixing frame, which is fixedly connected to the inner wall of the feed box, and a filter cloth is fixedly installed on the surface of the fixing frame.

[0011] Furthermore, a rotating shaft is rotatably connected to the inner wall of the feed box, and a material distribution plate is fixedly connected to the surface of the rotating shaft.

[0012] Furthermore, the material distribution plates are in multiple sets and are evenly distributed around the circumference, and the material distribution plates are located directly below the baffle plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a feeding device, the starting motor drives the screw to rotate, causing the movable table to slide up and down along the guide column. Under the action of the arc groove, the two sets of T-blocks move towards each other or away from each other along the T-groove. At the same time, the movable rod slides along the arc groove. When the movable rod moves downward, the baffle plate rotates along the fixed axis after losing the support of the movable rod, and the two sets of baffle plates gradually separate. When the movable rod moves upward, the movable rod pushes the two sets of baffle plates to gradually close. The opening and closing status and rotation angle of the baffle plates can be quickly understood by observing the pointer and scale groove. By setting up a feeding device, the opening and closing and angle of the two sets of baffle plates can be changed as needed. It can not only input water-coal slurry in batches and control its amount and speed entering the gasifier during feeding, but also close the feeding box to avoid direct contact with the outside when not feeding, thus effectively improving the applicability of the equipment.

[0015] 2. In this utility model, by setting up a filtration device, the filter cloth installed on the fixed frame filters the particles inside the coal-water slurry entering the feed box. When the coal-water slurry falls, it first contacts the distribution plate, pushing the distribution plate and the rotating shaft to rotate. This not only distributes the slurry and prevents a large amount of coal-water slurry from directly impacting the filter cloth and causing damage, but also uses the rotating distribution plate to beat the filter cloth, thereby improving the filtration effect. By setting up a filtration device, using the filter cloth to filter the particles inside the coal-water slurry, and using the distribution plate to distribute the coal-water slurry and beat the filter cloth, the filtration effect is improved, thus effectively enhancing the convenience of the equipment.

Detailed Implementation

[0023] Please see Figures 1-5 This utility model provides a technical solution: a feeding mechanism for a coal-water slurry gasifier, including a gasifier 1, a feeding box 2, an air inlet pipe 3, an air outlet pipe 4, and a feeding device 5. The feeding box 2 is fixedly connected to the top surface of the gasifier 1, the air inlet pipe 3 is fixedly connected to the top surface of the gasifier 1, the air outlet pipe 4 is fixedly connected to the side surface of the gasifier 1, and the feeding device 5 is disposed on the surface of the feeding box 2.

[0024] The specific setup and function of the feeding device 5 and the filtering device 6 will be described in detail below.

[0025] In this embodiment: the feeding device 5 includes a fixed shaft 501, which is fixedly connected to the inner wall of the feeding box 2. A baffle plate 502 is rotatably connected to the surface of the fixed shaft 501. An arc-shaped groove 503 is formed on the surface of the feeding box 2. A movable rod 504 is slidably connected to the surface of the arc-shaped groove 503. A motor 505 is fixedly installed on the surface of the feeding box 2. A screw 506 is fixedly connected to the output end of the motor 505. The screw 506 is rotatably connected to the inner wall of the feeding box 2. A movable table 507 is threadedly connected to the surface of the screw 506. A T-shaped groove 508 is formed on the surface of the movable table 507. A T-shaped block 509 is slidably connected to the surface of the T-shaped groove 508. The T-shaped block 509 is fixedly connected to the surface of the movable rod 504.

[0026] The effect achieved by the above components is as follows: the starting motor 505 drives the screw 506 to rotate, causing the movable table 507 to move up and down, so that the two sets of T-blocks 509 move towards each other or away from each other along the T-slot 508. At the same time, the movable rod 504 slides along the arc groove 503. When the movable rod 504 moves downward, the baffle plate 502 rotates along the fixed shaft 501 after losing the support of the movable rod 504, and the two sets of baffle plates 502 gradually separate. When the movable rod 504 moves upward, the movable rod 504 pushes the two sets of baffle plates 502 to gradually close.

[0027] Specifically, the movable rod 504 cooperates with the baffle plate 502, and the number of fixed shaft 501, baffle plate 502, arc groove 503, movable rod 504, T-slot 508 and T-block 509 are all in two sets and are arranged symmetrically in pairs.

[0028] The effect achieved by the above components is as follows: the two sets of baffles 502 are set to facilitate mutual cooperation, realize the batch input of coal-water slurry and control the input amount and speed.

[0029] Specifically, a pointer 510 is fixedly connected to the end of the movable rod 504 away from the T-block 509, and a scale groove 511 is opened on the surface of the feed box 2, with the pointer 510 cooperating with the scale groove 511.

[0030] The effect achieved by the above components is that the pointer 510 and the scale groove 511 are set to facilitate observation and quickly understand the opening and closing status and rotation angle of the baffle plate 502.

[0031] Specifically, guide columns 512 are fixedly connected to the surface of the feed box 2. There are two sets of guide columns 512 arranged symmetrically. The movable table 507 is slidably connected to the surface of the guide columns 512.

[0032] The effect achieved by the above components is that the two sets of guide columns 512 are set to prevent the movable table 507 from rotating with the screw 506, and to make the up-and-down movement of the movable table 507 more stable.

[0033] Specifically, a filter device 6 is provided on the surface of the feed box 2. The filter device 6 includes a fixing frame 61, which is fixedly connected to the inner wall of the feed box 2. A filter cloth 62 is fixedly installed on the surface of the fixing frame 61.

[0034] The effects achieved by the above components are as follows: the fixing frame 61 is set to facilitate the installation of the filter cloth 62, and the filter cloth 62 is set to filter the particles inside the coal-water slurry, thereby improving the gasification effect.

[0035] Specifically, a rotating shaft 63 is rotatably connected to the inner wall of the feed box 2, and a material distribution plate 64 is fixedly connected to the surface of the rotating shaft 63.

[0036] The effects achieved by the above components are as follows: the rotating shaft 63 is set to facilitate the rotation of the material distribution plate 64. The material distribution plate 64 is set to both distribute the coal-water slurry and beat the filter cloth 62 when rotating, thereby improving the filtration effect.

[0037] Specifically, there are multiple sets of material distribution plates 64, which are evenly distributed around the circumference and are located directly below the baffle plate 502.

[0038] The effect achieved by the above components is as follows: the multi-component material plate 64 is set directly below the baffle plate 502 so that when the coal-water slurry falls, the multi-component material plate 64 can be used to ensure that the shaft 63 can be rotated by the downward impact force of the coal-water slurry.

[0039] Working principle: By setting up the feeding device 5, the starting motor 505 drives the screw 506 to rotate, causing the movable table 507 to slide up and down along the guide column 512. Under the action of the arc groove 503, the two sets of T-blocks 509 move towards each other or away from each other along the T-groove 508. At the same time, the movable rod 504 slides along the arc groove 503. When the movable rod 504 moves downward, the baffle plate 502 rotates along the fixed shaft 501 after losing the support of the movable rod 504, and the two sets of baffle plates 502 gradually separate. When the movable rod 507 moves downward, the two sets of baffle plates 502 rotate along the fixed shaft 501. When the device moves upward, the movable rod 504 pushes the two sets of baffles 502 to gradually close. The opening and closing status and rotation angle of the baffles 502 can be quickly understood by observing the pointer 510 and the scale groove 511. By setting the feeding device 5, the opening and closing and angle of the two sets of baffles 502 can be changed as needed. This allows for the batch input of coal-water slurry during feeding and control of its amount and speed entering the gasifier 1. It also allows for the sealing of the feeding box 2 when not feeding to prevent direct contact with the outside world, thus effectively improving the applicability of the equipment.

[0040] Furthermore, by setting up a filtration device 6, the filter cloth 62 installed on the fixed frame 61 filters the particles inside the coal-water slurry entering the feed box 2. When the coal-water slurry falls, it first contacts the distribution plate 64, pushing the distribution plate 64 and the rotating shaft 63 to rotate. This not only distributes the slurry and prevents a large amount of coal-water slurry from directly impacting the filter cloth 62 and causing damage, but also uses the rotating distribution plate 64 to beat the filter cloth 62 to improve the filtration effect. By setting up the filtration device 6, using the filter cloth 62 to filter the particles inside the coal-water slurry, and using the distribution plate 64 to distribute the coal-water slurry and beat the filter cloth 62, the filtration effect is improved, which effectively enhances the convenience of the equipment.
