Problems solved by technology

In the port bulk grain unloading operation system, the most commonly used domestic dust collector is the MC pulse bag filter, which has played an important role in production, but there are still many problems, such as the small adaptability to dust concentration, explosion-proof , Poor moisture-proof performance, many wearing parts, need to be equipped with air compressor station to supply compressed air, dust arching in ash discharge hopper will cause blockage of dust collector, increase maintenance workload, etc. Therefore, there is an urgent need for a new dust removal device to Solve the above technical problems

Embodiment 1

[0011] Embodiment 1: see figure 1 , an environmental protection dust removal device, the environmental protection dust removal device includes an upper box, a middle box 4, an ash hopper part, a filter bag 5, an ash discharge system and auxiliary equipment, the filter bag is arranged in the middle box, and the middle box The lower part is equipped with an ash discharge system, wherein the upper box includes a clean air chamber, an inspection cover, and a clean air outlet; the middle box includes a perforated plate, an air inlet, an inspection door, and the ash hopper parts include an ash hopper box, an observation port The ash discharge system includes an ash unloading locker 7 and a rotary ash scraping device 6; the auxiliary equipment includes a guardrail and a ladder 1, etc., and the dust-laden airflow enters the middle box 4 tangentially from the air inlet, and a part of the coarser dust and The condensed dust particles fall into the bottom of the ash hopper along the wall...

Embodiment 2

[0012] Example 2: see figure 1 , as an improvement of the present invention, the ash hopper box adopts a flat-bottomed ash hopper structure. The ash discharge system consists of a scraper mechanism and an ash discharge locker. The dust falling into the ash hopper is forcibly scraped to the ash unloading port by the ash scraper, and then discharged through the ash unloader, which destroys the condition of the dust arching, not only prevents the dust from forming arches, but also reduces the efficiency of the whole machine. height, so that the dust can be smoothly discharged from the dust collector. The working principle is as follows: In the system design, reverse air flow and back blowing are adopted. The high-pressure dust-cleaning airflow generated by the high-pressure fan passes through the filter cloth in the opposite direction to the filter airflow, so that the dust on the surface falls off and falls into the ash hopper. This dust cleaning method distributes the airflo...

Abstract

The invention discloses an environment-friendly dust collection device. The environment-friendly dust collection device is characterized by comprising an upper box body, a middle box body (4), an ash bucket part, a filtering cloth bag (5), an ash discharging system and auxiliary equipment, wherein the filtering cloth bag is arranged in the middle box body, and the lower part of the middle box body is provided with the ash discharging system; the upper box body comprises a cleaning air chamber, an access cover and a clean air outlet, the middle box body comprises a multi-hole plate, an air inlet and an access door, and the ash bucket part comprises an ash bucket box body and a viewport; the ash discharging system comprises an ash discharging fastener (7) and a rotating ash scraping device (6), dust-containing airflow tangentially enters the middle box body (4) from an air inlet, one part of heavy dust and coagulated dust particles can fall down to the bottom of an ash bucket along the cylinder wall of the box body, a part of small dust flies in the filtering cloth bag (5) together with the airflow and is caught and filtered, and the clean air penetrates through a filter cloth to enter the upper box body and is finally discharged from the clean air outlet.

Description

technical field [0001] The invention relates to the field of dust removers, in particular to an environment-friendly dust remover. Background technique [0002] In the process of bulk grain unloading and transportation, a large amount of dust will be released in the atmosphere, causing environmental pollution and endangering human health. When the dusty air is dry and the dust concentration is high, the risk of dust explosion is also increased, threatening Safety of persons and equipment. The method of ventilation and dust removal is used to collect and purify the dusty gas, which can effectively protect the environment and reduce the probability of dust explosion. Environmental protection dust removal device is the most commonly used equipment for ventilation and dust removal. It mainly relies on the mechanism of filtration to separate dust from dusty gas, and has the characteristics of high efficiency and stable operation. In recent years, bag type dust removal technolog...
