[0004] When filtering waste gas, waste gas often enters dust collector from one end of dust collector and is filtered by multiple filter bags, but waste gas is more likely to contact filter bag close to the inlet end first, resulting in different service life of filter bags, and when a large amount of dust accumulates in the bottom of hopper of dust collector, the flow of waste gas can cause a large amount of large particle dust to flow continuously in the dust collector, which can damage the filter bag, and opening the ash discharge valve often requires stopping the equipment, reducing the processing efficiency. UTILITY MODEL CONTENTS

[0005] The utility model discloses a gas tank pulse bag type dust collector, through dust collector body, hopper and sealing cover, solve the problem that gas tank pulse bag type dust collector needs additional compressed air to backflush filter bag, and direct collection of atmosphere to filter bag backflush can cause pollution to filter bag, the airflow entering from one end of dust collector is more likely to contact filter bag close to the inlet end, when a large amount of dust accumulates in the bottom of hopper of dust collector, the flow of waste gas can cause a large amount of large particle dust to flow continuously in the dust collector.

[0006] To solve the above technical problems, the utility model is realized through the following technical schemes:

[0007] The utility model discloses a gas tank pulse bag type dust collector, including dust remover main part, ash bucket and seal cover, the dust remover main part is connected fixedly with the perforated plate in, the dust remover main part bottom is connected fixedly with ash bucket, a plurality of slow flow plates are connected fixedly in ash bucket from top to bottom, ash bucket bottom is penetrated with ash pipe and is welded, the dust remover main part top is connected fixedly with seal cover, seal cover one side is penetrated with high pressure pump and is connected, high pressure pump one side is provided with high pressure gas cylinder,

[0008] When the waste gas enters the ash bucket, the multiple slow flow plates can slow the flow of the waste gas, so that large particles are retained at the bottom of the ash bucket, and the air flow is delayed, avoiding damage to the dust filter bag caused by excessive air pressure. The perforated plate can disperse the flow rate and direction of the air flow, so that the air flow can be more evenly distributed in the entire space after passing through the perforated plate, allowing the air flow to contact multiple filter bags simultaneously. When a single filter bag surface is blocked, the other filter bag surface has few particles attached, which facilitates the unified cleaning and maintenance of multiple filter bags. The rotation of the conveying frame in the ash pipe can timely discharge the dust in the ash bucket, avoiding the accumulation of dust and the damage to the dust filter bag caused by the flow of a large amount of dust in the air flow in the dust remover main part. The dust remover does not need to be shut down, ensuring the dust removal efficiency. When the air flow is filtered, the high pressure pump pumps the air in the dust remover main part, and the filtered air is pumped into the high pressure gas cylinder for storage. When the air pressure in the high pressure gas cylinder reaches a threshold value, the high pressure gas cylinder is closed and the filtered air is discharged. When the dust filter bag needs to be backflushed, the high pressure gas cylinder is opened, and the high pressure air in the high pressure gas cylinder can quickly backflush the multiple dust filter bags under the action of the pressure difference. The air storage does not need to be additionally set, and the direct storage of external air is avoided, which prevents the pollution of the filter bag caused by the fine particles in the air.

[0009] Further, the dust remover main part is connected with a sealing support plate at the top, and multiple dust filter bags are connected with the sealing support plate at the bottom.

[0010] The multiple dust filter bags can filter the fine dust in the air, and the perforated plate can disperse the flow rate and direction of the air flow, so that the air flow can be more evenly distributed in the entire space after passing through the perforated plate, allowing the air flow to contact multiple filter bags simultaneously. When a single filter bag surface is blocked, the other filter bag surface has few particles attached, which facilitates the unified cleaning and maintenance of multiple filter bags.

[0011] Further, the ash bucket outer side bottom is welded with an air inlet pipe, support frames are welded around the ash bucket, and the air inlet pipe is located at the bottom of the plurality of flow slowing plates;

[0012] The plurality of flow slowing plates slow the air entering the ash bucket, so that large particles are retained at the bottom of the ash bucket, and the air flow is slowed down, thereby avoiding damage to the dust filter bag caused by excessive air pressure.

[0013] Further, a rotating motor is clamped and fixed on one side of the ash discharge pipe, a material conveying frame is clamped on one end of the rotating motor, the material conveying frame penetrates and is inserted into one side of the ash discharge pipe, and the outer side of the material conveying frame is attached to the inner wall of the ash discharge pipe.

[0014] The rotating motor drives the rotation of the material conveying frame, so that the large amount of dust particles entering the ash discharge pipe are conveyed and discharged, the accumulation of dust is avoided, the damage to the dust filter bag caused by the flow of a large amount of dust in the dust collector body is avoided, and the dust collection efficiency is ensured without stopping the dust collector.

[0015] Further, an exhaust pipe is penetrated and clamped on one side of the outer circumferential surface of the high-pressure pump, a connecting pipe and a solenoid valve are penetrated and clamped on the outer circumferential surface of the exhaust pipe, the connecting pipe is located between the solenoid valve and the high-pressure pump, the connecting pipe is penetrated and clamped at the top of the high-pressure gas cylinder, and a gas pressure gauge is penetrated and clamped at the top of the high-pressure gas cylinder.

[0016] When filtering air, the connecting pipe is opened and the solenoid valve is closed, the high-pressure pump is used to pump air in the dust collector body, and the filtered air is stored in the high-pressure gas cylinder. When the gas pressure reaches the threshold value through the gas pressure gauge, the connecting pipe is closed and the exhaust pipe is opened, so that the filtered air can be discharged through the exhaust pipe. When the dust filter bag needs to be backflushed, the solenoid valve is closed and the connecting pipe is opened, and the high-pressure air in the high-pressure gas cylinder can quickly backflush the plurality of dust filter bags under the action of the pressure difference. No additional air tank is needed to store air, and direct storage of external air is avoided, which avoids pollution of the filter bag by small particles in the air.

[0017] The utility model has the following beneficial effects:

[0018] This invention solves the problem of the time-consuming and labor-intensive process of backflushing filter bags to remove dust adhering to their surface, which requires additional compressed air and may contaminate the filter bags if atmospheric air is directly collected for backflushing. By setting up a sealing cap, this invention addresses these issues. When filtering air, the high-pressure air cylinder is opened and the solenoid valve is closed. The high-pressure pump draws air and stores the filtered air in the cylinder. When the pressure in the cylinder reaches a threshold, the cylinder is closed and the solenoid valve is opened to release the filtered air. When backflushing the filter bags is required, the solenoid valve is closed and the high-pressure air cylinder is opened. The high-pressure air in the cylinder quickly backflushes multiple filter bags, eliminating the need for an additional air tank for air storage and avoiding the contamination of filter bags caused by fine particles in the air.

[0019] This invention solves the problem of inconsistent filter lifespans in dust collectors by incorporating a main body and a dust hopper. In traditional dust collectors, exhaust gas typically enters from one end and passes through multiple filter bags, leading to uneven filter lifespan due to the higher rate of contact between the gas and the filter bags near the inlet. Furthermore, when large amounts of dust accumulate at the bottom of the dust hopper, the flow of exhaust gas can cause large dust particles to continuously move within the collector, potentially damaging the filter bags. Opening the ash discharge valve often necessitates shutting down the equipment, reducing processing efficiency. In this new design, the gas, upon entering the dust collector, is first slowed down by multiple flow-delay plates, allowing the gas to pass through a more efficient flow path. Large particles are retained at the bottom of the ash hopper. The perforated plate disperses the airflow velocity and direction, allowing the airflow to be more evenly distributed throughout the space. This enables the airflow to contact multiple filter bags simultaneously, preventing large-area blockage on one filter bag while minimizing particle adhesion on another. This facilitates unified cleaning and maintenance of multiple filter bags. The rotation of the conveyor frame in the ash discharge pipe promptly removes dust from the ash hopper, preventing dust accumulation and avoiding damage to the filter bags caused by large amounts of dust flowing with the airflow within the dust collector. Furthermore, the dust collector does not need to be shut down, ensuring dust removal efficiency. Attached Figure Description
