Description

Technical Field

[0001] This utility model belongs to the technical field of limestone processing equipment, and in particular relates to a centralized dust collection device for kiln tail. Background Technology

[0002] During limestone processing, a large amount of dust is generated at the kiln tail. This dust mainly contains limestone particles, unreacted chemical substances, and other impurities generated during processing. The indiscriminate emission of kiln tail dust not only causes serious environmental pollution, damages air quality, and affects the surrounding ecological balance, but also poses a great threat to the health of operators. Long-term inhalation may lead to serious diseases such as pneumoconiosis.

[0003] A Chinese patent with publication number CN215352728U discloses a device for collecting dust from the tail of a rotary kiln. The device includes a rotary kiln, with a main body on one side of the kiln. The main body contains an atomizing chamber. By incorporating an atomizing nozzle, a filter screen, an L-shaped connecting rod, a connecting sleeve, a reset spring, and a compression spring, the device can improve the filtration and collection of dust particles inside the tail gas when purifying the dust from the kiln tail, effectively preventing dust from adsorbing onto the filter screen.

[0004] However, the above-mentioned technology uses a single filtration structure, which has extremely poor adaptability to different working conditions. The limestone processing technology will change due to factors such as product demand and raw material characteristics, resulting in large fluctuations in the properties and concentration of dust generated at the kiln tail. A single filtration structure cannot flexibly cope with these changes and cannot guarantee efficient dust collection under various conditions. Utility Model Content

[0005] The purpose of this utility model is to provide a centralized dust collection device for kiln tails. By combining a filtration mechanism and a purification mechanism, it solves the problem that existing collection devices with a single filtration structure have extremely poor adaptability to different working conditions and cannot meet filtration requirements.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a centralized dust collection device for kiln tail, comprising a base plate, with support columns fixedly connected to the four corners of the top of the base plate. A filter mechanism is fixedly connected to the top of each support column, and a purification mechanism is connected to one side of the filter mechanism. The filter mechanism includes a housing, the bottom of which is fixedly connected to the support columns. A dust inlet pipe is connected to the top of one side of the housing. Mounting brackets are fixedly connected to both sides of the top of the inner cavity of the housing, and a filter plate is installed at the bottom of each mounting bracket. A dust outlet is provided at the bottom of the housing, and a conveying pipe is connected to the top of one side of the housing. A shell is connected to one side of the conveying pipe, and the inner cavity of the shell... A filter screen is installed, and a motor is mounted on the surface of the filter screen. A cleaning brush is fixedly connected to the output end of the motor. One side of the cleaning brush contacts the filter screen. The base plate and support columns support the housing, ensuring the stability of the overall structure. The collected dust enters the interior of the housing through the dust inlet pipe. Under the action of the filter plates, most of the dust particles can be collected. A hopper is connected to the bottom of the housing, and a control valve is installed on one side of the hopper to facilitate the rapid discharge of the collected dust, thereby improving the cleaning effect. After being filtered by two filter plates, most of the dust particles are retained inside the housing.

[0008] The present invention is further configured such that the purification mechanism includes a housing, one side of which is connected to an outer shell, and four columns are fixedly connected to the bottom of the housing. A water tank is fixedly connected to the bottom of each column, and a pump body is fixedly connected to one side of the top of the water tank. A connecting pipe is connected to one side of the pump body, and the side of the connecting pipe away from the pump body extends into the inner cavity of the housing. A spray pipe is connected to one side of the connecting pipe. Some dust particles enter the interior of the collection hopper through the filter screen, while unfiltered dust enters the interior of the housing and is effectively purified after being sprayed. The interior of the water tank is equipped with a wastewater filtration structure, which enables the purpose of recycling.

[0009] The present invention is further configured such that an induced draft fan is connected to the top of the shell, and a grid is fixedly connected to the top of the induced draft fan. Under the action of the induced draft fan, a negative pressure airflow is formed inside the shell to collect dust. The power of the induced draft fan is reasonably configured according to the actual working conditions of the kiln tail and the required dust collection volume, so as to provide sufficient suction to ensure that the dust-laden gas enters the interior of the collection device smoothly.

[0010] The present invention is further configured such that guide plates are fixedly connected to the bottom of both sides of the inner cavity of the box, and one side of the guide plate extends to the bottom of the filter plate. The guide plate can guide dust particles into the interior of the hopper for collection, thereby improving the cleaning effect.

[0011] The present invention is further configured such that a collection hopper is connected to the bottom of the outer shell, and a cleaning pipe is connected to the bottom of the collection hopper. The collection hopper and the cleaning pipe can collect the dust particles cleaned inside the outer shell, thereby improving the filtration effect of the device.

[0012] The present invention is further configured such that a drain pipe is connected to the top of the water tank, the top of the drain pipe is connected to the shell, the bottom of the drain pipe is connected to the water tank, so that the wastewater mixed by spraying can flow into the interior of the water tank, be filtered and recycled.

[0013] The present invention is further configured such that a fixing frame is fixedly connected to one side of the motor, and one side of the fixing frame is fixedly connected to the inner wall of the outer casing. The fixing frame can fix the motor and ensure the stability of the motor installation.

[0014] The present invention is further configured such that a drain pipe is connected to the bottom of one side of the water tank, and a valve is provided on one side of the drain pipe. The drain pipe and the valve facilitate the cleaning of dust and dirt that have settled inside the water tank.

[0015] This invention has the following beneficial effects: By adopting a spray dust suppression method, this invention can effectively capture suspended dust particles in the air. Through the combination of water and dust, the dust settles rapidly, greatly reducing the amount of dust emitted into the atmosphere, better meeting environmental protection requirements, and reducing pollution to the surrounding environment. In terms of equipment maintenance, spray dust suppression can reduce dust concentration, reduce the frequency of clogging of other filter components, extend their service life, thereby reducing maintenance costs and equipment downtime, and ensuring continuous and stable production operation.
