Description

Technical Field

[0001] This utility model relates to the technical field of dust collection, and in particular to a dust collection device for silo feeding. Background Technology

[0002] In the fertilizer production process, after the fertilizer granules are produced, they need to be added to the silo through the feeding port at the top of the silo for storage. When the fertilizer granules are added to the silo, due to the mutual friction between the granules and the collision between the granules and the silo wall, a large amount of dust is generated around the silo, affecting the working environment. Therefore, a dust collection mechanism is needed to collect the dust in the air around the silo. In the prior art, the utility model patent with patent application number 202223379111.7 discloses a dust filtration device, which mainly consists of a filter cylinder and a filter screen. When in use, outside air enters the filter cylinder and is then filtered by the filter screen. However, it has the following problems during use: after a period of use, more and more impurities adhere to the filter screen in the filter cylinder, resulting in a decrease in filtration efficiency. Therefore, it is necessary for staff to manually clean the impurities on the filter screen regularly. However, relying on manual cleaning of the impurities on the filter screen is labor-intensive and inconvenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a dust collection device for silo loading that can assist workers in cleaning dust from the filter mechanism, is easy to use, has low labor intensity, and is highly practical.

[0004] This utility model discloses a dust collection device for silo loading, comprising a base plate, a support frame, a support plate, and a filter cylinder. The support plate is fixedly mounted on the base plate via the support frame, and the filter cylinder is fixedly mounted on the support plate, with a chamber inside the filter cylinder. It also includes an induced draft fan, an exhaust pipe, a filtration mechanism, a lifting mechanism, a cleaning mechanism, and an air inlet mechanism. The output end of the air inlet mechanism communicates with the filter cylinder chamber, the input end of the induced draft fan communicates with the upper part of the filter cylinder chamber, and the output end of the induced draft fan is provided with an exhaust pipe. The filtration mechanism is installed inside the filter cylinder chamber and on the lifting mechanism. The cleaning mechanism is installed on the filter cylinder. The mechanism has a cleaning function; the input end of the air intake mechanism is located above the feeding port at the top of the hopper; when material needs to be fed into the hopper, the induced draft fan is turned on at the same time to reduce the pressure in the filter cartridge, thereby allowing the dust near the top of the hopper to enter the filter cartridge through the air intake mechanism. After that, the dust is filtered out by the filter mechanism, and the clean air is discharged through the induced draft fan and the exhaust pipe. When it is necessary to clean the dust on the filter mechanism, the cleaning mechanism is turned on to clean the dust adhering to the filter mechanism. It can assist workers in cleaning the dust on the filter mechanism, is easy to use, has low labor intensity, and is highly practical.

[0005] Preferably, the air intake mechanism includes a support plate, an air intake funnel, an air delivery pipe, and a conveying pipe.

The air intake funnel is located above the hopper. When it is necessary to clean the dust near the top of the hopper, the induced draft fan is turned on to reduce the pressure in the filter cylinder. This allows the dust-laden air above the hopper to enter the lower part of the filter cylinder cavity sequentially through the air intake funnel, the air delivery pipe, and the conveying pipe. After that, the dust-laden air is filtered by the filtration mechanism and discharged through the induced draft fan and the exhaust pipe.

The connecting frame is mounted on the upper end of the ring and is mounted on a lifting mechanism. The conveying pipe is located below the ring, and the input end of the induced draft fan is located above the ring. After air enters the filter cylinder through the conveying pipe, the air is filtered by the filter screen at the lower end of the perforated plate and then enters the upper part of the filter cylinder chamber through the perforated plate. After that, the clean air is discharged through the induced draft fan and the exhaust pipe.

[0007] Preferably, the cleaning mechanism includes a support frame and an ultrasonic generator. A drain pipe communicating with the chamber is provided at the lower part of the filter cartridge, and a valve is installed on the drain pipe.

A transducer is installed on the output end of the ultrasonic generator. Water is provided at the lower part of the filter cartridge chamber, and the output end of the ultrasonic generator is submerged in the water. The output end of the delivery pipe is located above the liquid surface. When it is necessary to clean impurities on the filter screen at the lower end of the perforated plate, the hydraulic cylinder is opened, causing the connecting frame to lower the ring and the perforated plate, allowing the perforated plate to descend into the water at the lower part of the filter cartridge chamber. Then, the ultrasonic generator is turned on to promote water oscillation, using the water to clean the dust adhering to the filter screen at the lower end of the perforated plate, facilitating the cleaning of the filter screen. Afterward, the ring and the perforated plate are raised again, facilitating the cleaning of the perforated plate.

The hydraulic cylinder is fixedly installed on the upper end of the filter cylinder, and the push rod is slidably installed on the filter cylinder. The lower end of the push rod is provided with a mounting plate, which is fixedly installed on the connecting frame. The power output end of the hydraulic cylinder is connected to the push rod.
