Description

Technical Field

[0001] This utility model relates to the field of pneumatic ash conveying technology, and in particular to a uniform feeding device for pneumatic ash conveying. Background Technology

[0002] Pneumatic conveying, also known as airflow conveying, utilizes the energy of airflow to transport granular materials along the airflow direction within a closed pipeline. It is a specific application of fluidization technology. Pneumatic conveying devices have a simple structure, are easy to operate, and can perform horizontal, vertical, or inclined conveying. During pneumatic conveying, ash material needs to be supplied into the pneumatic conveying pipeline through a feeding device.

[0003] The pneumatic ash conveying feeding and discharging device disclosed in CN114560301B, through the cooperation of a vibration mechanism and a scraping mechanism, allows the angled dial and the transmission gear to rotate simultaneously after the transmission component is started. The angled dial can simultaneously move multiple sets of limit pins, causing multiple sets of hammer rods to hammer the transmission cylinder. Through the action of the transmission cylinder, the ash hopper and the ash conveying pipe can be effectively vibrated at the same time. The rotation of the transmission gear can cause the movable gear to drive the scraper to scrape off the micro-dust adhering to the inner wall of the ash hopper. During the scraping process, the accumulated micro-dust can fall quickly into the interior of the ash conveying pipe due to its own gravity and the influence of the vibration force, without causing blockage at the bottom port of the ash hopper.

[0004] However, this pneumatic ash conveying feeding and discharging device has the following disadvantages: it is not convenient to dry the ash material evenly, and the ash material is prone to condensing into clumps when the moisture content is high, resulting in uneven feeding and difficulty in conveying the ash material. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The technical problem solved by the utility model is to provide a highly practical, simple, and structurally simple uniform feeding device for pneumatic ash conveying, which solves the problems mentioned in the background art, such as the inconvenience of uniform drying of ash, the tendency of ash to clump together when the moisture content is high, resulting in uneven feeding and difficulty in conveying ash.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a uniform feeding device for pneumatic ash conveying, comprising an ash hopper, a support frame fixedly installed on the top of the outer surface of the ash hopper, a servo motor fixedly installed on the top surface of the support frame, and a mixing mechanism fixedly installed at the output end of the servo motor; a cavity is opened in the inner wall of the ash hopper, an electric heating plate is fixedly installed inside the cavity, a feed pipe is fixedly installed at the bottom of the ash hopper, and a valve is fixedly installed at the bottom of the outer surface of the feed pipe.

[0009] As a further embodiment of this utility model, the mixing mechanism includes a connecting shaft with a servo motor output end fixedly installed, a bucket wall scraper fixedly installed on the top of the surface of the connecting shaft, a material dispersing rod fixedly installed in the middle of the surface of the connecting shaft, a discharge auger fixedly installed at the bottom of the connecting shaft, and a crushing blade fixedly installed at the bottom of the mixing mechanism. The discharge auger facilitates the conveying of ash material in the ash hopper to the pneumatic conveying pipeline.

[0010] As a further embodiment of this utility model, a temperature controller is electrically connected to one side of the heating plate. The temperature controller is fixedly installed on one side of the ash hopper and is used to control the heating temperature of the heating plate.

[0011] As a further embodiment of this utility model, the number of the material dispersing rods is several groups, and the several groups of material dispersing rods are distributed from top to bottom along the axial direction on the surface of the connecting shaft. The material dispersing rods are used to disperse clumps of ash material.

[0012] As a further embodiment of this utility model, the discharge auger is rotatably sleeved inside the feed pipe, facilitating material discharge.

[0013] As a further embodiment of this utility model, a through hole is provided in the middle of the top surface of the support frame. The through hole is adapted to the output end of the servo motor, and the through hole facilitates the passage of the servo motor output end.

[0014] As a further embodiment of this utility model, the surface of the material distribution rod is provided with several protruding vertical rods, and the bottom of the material distribution rod extends into the interior of the feed pipe.

[0015] (III) Beneficial Effects

[0016] This utility model provides a uniform feeding device for pneumatic ash conveying, which has the following beneficial effects:

[0017] 1. This uniform feeding device for pneumatic ash conveying uses an electric heating plate and a mixing mechanism. The electric heating plate heats up after passing through, and the heating temperature of the electric heating plate is controlled by a temperature controller to dry the ash material inside the ash hopper. When the servo motor drives the mixing mechanism to rotate, the material dispersing rod breaks up the ash material that has clumped together due to high humidity, so that the ash material is heated and dried evenly. The ash material can then enter the pneumatic ash conveying pipeline evenly, which facilitates ash conveying.

[0018] 2. This uniform feeding device for pneumatic ash conveying, through the setting of the mixing mechanism, allows the servo motor to drive the hopper wall scraper and the discharge auger to rotate. The hopper wall scraper scrapes off the ash material adhering to the inner wall of the ash hopper. When the ash material falls into the feed pipe, the servo motor drives the discharge auger to rotate, which facilitates the ash material entering the pneumatic conveying pipeline and avoids ash material blockage affecting the conveying. When it is conveyed to the bottom of the feed pipe, the crushing blade further disperses the ash material, preventing the ash material from adhering to each other when the discharge auger pushes it out of the feed pipe.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a uniform feeding device for pneumatic ash conveying, including an ash hopper 1, a support frame 2 fixedly installed on the top of the outer surface of the ash hopper 1, a servo motor 3 fixedly installed on the top surface of the support frame 2, and a mixing mechanism 4 fixedly installed at the output end of the servo motor 3; through the setting of the mixing mechanism 4, the servo motor 3 can drive the hopper wall scraper 402 and the discharge auger 404 to rotate. The hopper wall scraper 402 scrapes off the ash material adhering to the inner wall of the ash hopper 1. When the ash material falls into the feed pipe 6, the servo motor 3 drives the discharge auger 404 to rotate, which can facilitate the ash material to enter the pneumatic conveying pipe and avoid the ash material blocking the conveying. When it is conveyed to the bottom of the feed pipe 6, the crushing blade 9 further disperses the ash material to prevent the ash material from adhering to each other when the discharge auger 404 pushes it out of the feed pipe 6.

[0026] The inner wall of the ash hopper 1 has a cavity, and an electric heating plate 5 is fixedly installed inside the cavity. Through the setting of the electric heating plate 5 and the mixing mechanism 4, the electric heating plate 5 heats up after passing through. The heating temperature of the electric heating plate 5 is controlled by the temperature controller 8 to dry the ash material inside the ash hopper 1. When the servo motor 3 drives the mixing mechanism 4 to rotate, the dispersing rod 403 breaks up the ash material that has clumped together due to high humidity, so that the ash material is heated and dried evenly. The ash material can enter the pneumatic ash conveying pipe evenly, which is convenient for ash conveying. The bottom of the ash hopper 1 is fixedly installed with a feed pipe 6, and a valve 7 is fixedly installed on the bottom of the outer surface of the feed pipe 6.

[0027] The mixing mechanism 4 includes a connecting shaft 401 with the output end of the servo motor 3 fixedly installed, a bucket wall scraper 402 fixedly installed on the top of the surface of the connecting shaft 401, a material dispersing rod 403 fixedly installed in the middle of the surface of the connecting shaft 401, and a discharge auger 404 fixedly installed at the bottom of the connecting shaft 401.

[0028] With the mixing mechanism 4 in place, the hopper wall scraper 402 scrapes off the ash material adhering to the inner wall of the ash hopper 1. When the ash material falls into the feed pipe 6, the servo motor 3 drives the discharge auger 404 to rotate, which facilitates the ash material entering the pneumatic conveying pipe. The material dispersing rod 403 breaks up the ash material that has clumped together due to high humidity. When it is conveyed to the bottom of the feed pipe 6, the crushing blade 9 further breaks up the ash material, preventing the ash material from adhering to each other again when it is pushed out of the feed pipe 6 by the discharge auger 404.

[0029] A temperature controller 8 is electrically connected to one side of the heating plate 5, and the temperature controller 8 is fixedly installed on one side of the exterior of the ash hopper 1.

[0030] The temperature controller 8 is configured to control the heating temperature of the heating plate 5.

[0031] The number of material release rods 403 is several groups, and the several groups of material release rods 403 are distributed axially from top to bottom on the surface of the connecting shaft 401.

[0032] By setting up the material dispersing rod 403, the material dispersing rod 403 will break up the ash material that has clumped together due to high humidity, so that the ash material can be heated and dried evenly.

[0033] The discharge auger 404 is rotatably sleeved inside the feed pipe 6.

[0034] With the setting of the discharge auger 404, when the ash falls into the feed pipe 6, the servo motor 3 drives the discharge auger 404 to rotate, which can facilitate the ash to enter the pneumatic conveying pipe and avoid the ash from blocking the conveying.

[0035] A through hole is provided in the middle of the top surface of the support frame 2, and the through hole is adapted to the output end of the servo motor 3.

[0036] The through hole facilitates the passage of the output end of the servo motor 3.

[0037] The surface of the material handling rod 3 is provided with several raised vertical rods, and the bottom of the material handling rod 3 extends into the inside of the feed pipe 6. The material handling rod 3 facilitates the conveying of ash material into the pneumatic ash conveying equipment.

[0038] The model of temperature controller 8 is MTAIS-MT9. The above models can be selected according to the actual situation.

[0039] In this invention, the working steps of the device are as follows:

[0040] First step: The ash material is injected into the ash hopper 1. The heating plate 5 heats up after passing through, and the heating temperature of the heating plate 5 is controlled by the temperature controller 8 to dry the ash material inside the ash hopper 1. When the servo motor 3 drives the mixing mechanism 4 to rotate, the dispersing rod 403 breaks up the ash material that has clumped together due to high humidity, so that the ash material is heated and dried evenly. The ash material can enter the pneumatic ash conveying pipe evenly, which is convenient for ash conveying. When it is conveyed to the bottom of the feed pipe 6, the crushing blade 9 further breaks up the ash material to prevent the ash material from sticking together again when it is pushed out of the feed pipe 6 by the discharge auger 404.

[0041] Second step: Connecting shaft 401 can drive the bucket wall scraper 402 and discharge auger 404 to rotate. The bucket wall scraper 402 scrapes off the ash material adhering to the inner wall of the ash bucket 1. The ash material falls into the feed pipe 6. When the discharge auger 404 rotates, it can facilitate the ash material to enter the pneumatic conveying pipe and avoid ash material blockage affecting the conveying.

[0042] The third step: The ash material is fed into the pneumatic conveying equipment through the feed pipe 6 for conveying.
