Description

Technical Field

[0001] This utility model relates to the field of screening and slag discharge technology, specifically a screening and slag discharge scraper for biomass boilers. Background Technology

[0002] Biomass energy is a clean energy source that uses plants as raw materials, making it both environmentally friendly and renewable. With a wide range of raw material sources, it is often referred to as "green coal." Biomass pellet fuel differs from directly burned biomass fuel and is a development project encouraged by the National Eleventh Five-Year Plan (NDRC Document No. 2875), demonstrating its strong vitality.

[0003] Existing boiler furnace structures cannot fully adapt to the combustion of biomass pellet fuel, failing to support its complete combustion. This leads to problems such as incomplete combustion, unsatisfactory burnout rates, and energy waste. To address this, a biomass boiler (see patent number: 201620887495.9) is provided, comprising a furnace, boiler body, hollow stepped protrusion device, grate reducer, grate, air duct, blower, air passage, and pusher. The boiler body is located at the upper end of the furnace, and air ducts are installed inside the furnace. The upper end of the air ducts is equipped with… A hollow stepped protrusion device is added to a biomass boiler. The lower end of the air duct has an air channel connected to a blower. A grate is located at the bottom of the furnace, with a grate reducer connected to one side. A feed inlet is located on one side of the furnace, and a pusher is located on the side of the feed inlet, mounted on a support platform. By adding this hollow stepped protrusion device to a biomass boiler, combustion air is preheated by the blower and air duct before being sprayed out from the air outlet to fully combust with the fuel. This improves combustion efficiency and increases service life.

[0004] Currently, most biomass boilers on the market do not have ash scrapers, which requires manual removal of the residue, greatly increasing the workload and making them less safe to use. In addition, some biomass boilers do not have ash screening devices, making them less practical. Utility Model Content

[0005] The purpose of this utility model is to address the problems that most existing biomass boilers on the market do not have slag scrapers, which requires manual removal of residues, greatly increasing the workload and making them less safe to use. In addition, some biomass boilers do not have slag screening devices, resulting in poor practicality. This utility model provides a biomass boiler slag screening scraper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biomass boiler ash discharge scraper, comprising:

[0007] The main body of the device is used to support and protect the slag discharge scraper of the biomass boiler.

[0008] The incineration component is located in the middle of the interior of the device body;

[0009] The screening component is located at the bottom of the incineration component;

[0010] The incineration assembly includes a support frame, a gear set at the top of the support frame, an asynchronous motor at the top of the gear set, scrapers on both sides of the bottom of the support frame, a fixed plate at the bottom of the two sets of scrapers, and a baffle at the middle position of the fixed plate. The screening assembly includes a rotating frame, multiple sets of rollers on the outside of the rotating frame, protrusions on the side of the multiple sets of rollers away from the rotating frame, a drive motor at the top of the middle position of the rotating frame, a screening screen at the middle position of the rotating frame, and multiple pressure rollers at the top of the screening screen.

[0011] As a further embodiment of this utility model: the device body includes a shell, a feeding hopper is provided on one side of the middle position of the shell, rubber pads are provided at the four corners of the bottom of the shell, a heating water tank is provided at the top inside the shell, a flue is provided on one side of the heating water tank, and a collection box is provided at the bottom inside the shell.

[0012] As a further improvement of this utility model: a locking tooth is provided on one side of the bottom of the baffle, and a gear is provided on one side of the locking tooth. The baffle is movably connected to the fixed plate through the locking tooth and the gear.

[0013] As a further improvement of this utility model, the two sets of scrapers are rotatably connected to the support frame via a gear set and an asynchronous motor.

[0014] As a further improvement of this utility model, the exterior of each of the multiple sets of pressure rollers is provided with grinding teeth.

[0015] As a further improvement of this utility model: each of the multiple sets of rollers is provided with a limiting rod on the side near the rotating frame, and each of the multiple sets of limiting rods is provided with a spring on the outside, and the rotating frame vibrates through the rollers, limiting rods and springs.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. After combustion is complete, the asynchronous motor is started through the set incineration components. The output of the asynchronous motor drives the two sets of scrapers to rotate through the gear set, and at the same time drives the gear at the bottom to rotate. Through the meshing connection with the clamping gear, the baffle moves backward and pushes the combustion residue into the screening component. This device is convenient to use and simple to operate, and can facilitate the scraping of incineration residue, making it convenient to use.

[0018] 2. The set screening components drive the output of the motor to rotate, which in turn drives the rotating frame to rotate, and at the same time drives multiple sets of rollers to rotate. While rotating, the rollers generate vibration through the protrusions and springs, and the calcined residue is crushed by multiple sets of pressure rollers and screened by a screening screen. Finally, it falls into the collection box for collection. This device is convenient to use and simple to operate. It can crush and screen residues to meet different application requirements.
