Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to an anti-overflow device for a dust collector chute. Background Art

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life, and ease of operation and management of the dust collector are also important factors to consider its performance. Dust collectors are commonly used facilities in boilers and industrial production.

[0003] As the core auxiliary equipment in the purification process of aluminum production, the dust collector plays an irreplaceable role in daily production. The chute is an important material transmission channel of the dust collector, just like the blood vessels of the human body. The smoothness of the transmission channel directly affects the smooth operation of the dust collector. Since alumina contains more impurities during production and transportation, long-term operation can easily cause impurity deposition in the dust collector chute. If the feeding is not stable, the fresh chute of the dust collector will overflow, resulting in material waste and damage to environmental protection and smooth operation. Utility Model Content

[0004] In view of the technical problems in the prior art, the utility model provides a dust collector chute anti-overflow device, which reminds the staff to adjust the feeding in time when the flow in the chute exceeds the standard, thereby avoiding the overflow of the dust collector chute, effectively ensuring the smooth operation of the dust collector and reducing material waste.

[0005] A dust collector chute overflow prevention device includes a chute, a pressure relief component, an alarm, a flow detector, a control box, and an electric control valve of the chute arranged in the chute. The chute is connected to the material loading position, the pressure relief component and the flow detector are installed at the end of the chute, the pressure relief component is connected from the top of the chute to the inside of the chute, the flow detector is electrically connected to the control box, and the control box is communicatively connected to the alarm and the electric control valve of the chute.

[0006] Furthermore, the pressure relief assembly includes a pressure relief pipe, a smoke pipe and a discharge pipe. The pressure relief pipe extends into the chute, the other end of the pressure relief pipe is connected to the bottom of one end of the smoke pipe, and the discharge pipe is connected to the bottom of the other end of the smoke pipe.

[0007] Furthermore, a discharge valve is connected in series to the discharge pipe.

[0008] Furthermore, the flow detector is installed in the pressure relief pipe, and the position of the flow detector in the chute is adjustable.

[0009] Furthermore, a pressure relief electric control valve is connected in series to the pressure relief pipe, and the pressure relief electric control valve is electrically connected to the control box.

[0010] Furthermore, it also includes a display, which is electrically connected to the control box.

[0011] The utility model discloses a dust collector chute overflow prevention device. When the fresh chute overflows due to unstable feeding, the overflow material is discharged from the chute through the pressure relief component, and the material flow of the chute is monitored by the flow detector. When the flow exceeds the preset flow of the flow detector, the communication alarm of the control box alarms, thereby reminding the staff to adjust the feeding amount in time when the flow in the chute exceeds the standard, avoiding the overflow of the dust collector chute, effectively ensuring the smooth operation of the dust collector and reducing material waste.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0017] like Figure 1 and Figure 2The dust collector chute overflow prevention device shown in the figure comprises a chute 1, a pressure relief component 2, an alarm 3, a flow detector 4, a control box, and a chute electric control valve 10 arranged in the chute 1. The chute 1 is connected to the material loading position, the pressure relief component 2 and the flow detector 4 are installed at the end of the chute 1, the pressure relief component 2 is connected from the top of the chute 1 to the inside of the chute 1, the flow detector 4 is electrically connected to the control box, and the control box is connected to the alarm 3 and the chute electric control valve 10 for communication; the material enters the chute 1 from the feeding port of the chute 1, and the flow detector is used to monitor the flow rate in the chute 1 and the height of the material in the chute 1. When the material in the chute 1 When the material flow exceeds the set flow peak, the flow detector 4 sends a signal to the electric control box, and the electric control box sends an alarm signal to the alarm 3. At the same time, the electric control box controls the chute electric control valve 10 through PID regulation to increase the valve opening, so that the material accumulated at the feeding position can flow through the chute 1 in time, and the material exceeding the flow peak enters the pressure relief component 2, and is discharged from the pressure relief component 2 to the chute 1, and the material is recycled, so that when the flow in the chute 1 exceeds the standard, the staff can be reminded to adjust the feeding in time, avoiding the overflow of the dust collector chute 1, effectively ensuring the smooth operation of the dust collector and reducing material waste.
