Description

A bag filter that can improve the speed of pulse inspection

technical field

The utility model relates to the technical field of dust removal devices, in particular to a bag dust collector which can improve the speed of pulse inspection.

Background technique

For the production process of manganese-zinc ferrite powder, it is divided into raw material mixing slurry, one-time sand milling, one-time spray granulation, pre-calcination and coarse crushing, pre-fired material slurry, secondary sand-milling and secondary spray granulation production The process, because it belongs to the milling process, inevitably generates dust during the production process, so a large amount of dust removal equipment is required. The working principle of the dust removal equipment is to generate negative pressure through the fan, and then use the filter bag in the bag filter to filter the dust. In order to prevent the bag from clogging the bag due to the adsorption of dust, the bag is blown by pulse blowing. Therefore, improving the efficiency of pulse inspection is an extremely effective measure for the continuous operation of production and the reduction of production costs.

However, there are the following problems in the dust removal of the current bag filter:

1. There are multiple pulse pipelines on a bag filter, and the compressed air required for the pulse is provided by an air bag. It is difficult to judge which pulse pipeline is damaged, which prolongs the maintenance time.

2. Since the gas transmission pipelines of multiple impulse pipelines are connected in series, they must be shut down for maintenance, which affects the continuity of production.

The failure of the dust removal system will cause the entire spray granulation system to shut down. After repairing and restarting the black spraying system, the system needs 1 hour to stabilize, resulting in fluctuations in product quality.

Utility model content

In order to solve the above technical problems, the utility model provides a bag filter that can increase the pulse inspection speed, which can shorten the inspection time and downtime, realize continuous production operation, reduce production costs, and stabilize product quality.

The technical scheme adopted by the utility model is: a bag filter that can improve the speed of pulse maintenance, including a dust collector body, a pulse tube and an air bag, the dust collector body is connected to the gas outlet of the pulse tube, and the air bag is connected to the pulse tube. The air bag is connected to the compressed air source through the first manual valve, the pulse tube is provided with a solenoid valve, and a second manual valve is provided between the solenoid valve and the intake end of the pulse tube. There is a third manual valve between the electromagnetic valve and the gas outlet of the pulse tube, a pressure gauge is installed between the third manual valve and the electromagnetic valve, and a differential pressure gauge is installed on the dust collector body.

Preferably, there are 8 pulse tubes.

The beneficial effects of the utility model are: the bag dust collector can quickly judge the pulse failure point, and carry out independent maintenance without shutting down, which can shorten the maintenance time and downtime, ensure the continuous operation of production, reduce production costs, and stabilize products. quality.

detailed description

In order to deepen the understanding of the utility model, the utility model will be further described below in conjunction with the embodiments and accompanying drawings. The embodiment is only used to explain the utility model, and does not constitute a limitation to the protection scope of the utility model.

As shown in Figure 1, a bag dust collector that can improve the speed of pulse inspection includes a dust collector body 1, eight pulse tubes 10 and air bags 4, the dust collector body 1 is connected to the gas outlet of the pulse tubes 10, and the air bag 4 is connected to the gas bag. The intake end of the pulse tube 10 is connected, the air bag 4 is connected with the compressed air source 2 through the first manual valve 3, the pulse tube 10 is provided with a solenoid valve 6, and a valve is provided between the solenoid valve 6 and the intake end of the pulse tube 10. The second manual valve 5, a third manual valve 8 is provided between the solenoid valve 6 and the gas outlet of the pulse tube 10, a pressure gauge 7 is installed between the third manual valve 8 and the solenoid valve 6, and a pressure gauge 7 is installed on the dust collector body 1. There is a differential pressure gauge 9. When the differential pressure of the bag filter is found to be abnormal and the differential pressure is > 0.5 MPa, it means that the eight impulse tubes are faulty.

The detection process is as follows: when the differential pressure displayed on the differential pressure gauge 9 is > 0.5 MPa, it means that there is a failure in the 8 impulse pipelines. At this time, close the third manual valve 8 and check the pressure gauge 7. If the pressure of the pressure gauge 7 > 0.5 MPa, indicating that the diaphragm of the solenoid valve 6 is damaged. Close the second manual valve 5 and the third manual valve 8 during maintenance, and then replace the diaphragm when the other pulse pipelines are working normally. After replacing the diaphragm, open the third The manual valve 8 and the second manual valve 5 are enough. If the pressure of the pressure gauge 7 is zero, it means normal. Check the remaining pulse lines one by one. This method can quickly judge the fault point of the pulse, and carry out independent maintenance without stopping the machine, ensuring the continuous operation of production.
