Problems solved by technology

[0003] 1. Because the pressure safety valve is generally in the open air, the moving parts such as springs are easy to rust, resulting in the failure of the pressure safety valve, so frequent inspection and maintenance are required;
[0004] 2. After the spring-type pressure safety valve has been operated once, it must be repaired and maintained in time, otherwise the cement and other powders trapped in the valve body will form hard lumps after absorbing moisture in the air, resulting in the pressure safety valve not being able to open or close tightly. , can not play its security role;
[0005] 3. The maintenance of the safety valve needs to be handled by climbing the ladder to the top of the powder warehouse about 20 meters above the ground, which is very troublesome

Embodiment 1

[0025] Such as figure 1 As shown, the intelligent dust collection system of the present invention includes a pressure safety valve 2, a pressure detection unit 3, a signal receiving unit 4, a control output unit 5 and a dust collector 6 connected in sequence and forming a control circuit; the signal receiving unit 4 and the control output The unit 5 is combined into a control unit; the pressure detection unit 3 is used to detect the pressure value of the pressure safety valve 2; the signal receiving unit 4 presets the pressure value and is electrically connected with the pressure detection unit 3 to receive the pressure detected by the pressure detection unit 3 Real-time pressure value; one end of the control output unit 5 is electrically connected to the signal receiving unit 4, and the other end is electrically connected to the dust collector 6, and the control output unit 5 compares the real-time pressure value detected by the pressure detection unit 3 with the preset pressu...

Embodiment 3

[0029] Such as figure 2 As shown, the powder silo of the present invention includes a silo body 1, a protective cover 7 with vents, and the intelligent dust collection system described in Embodiment 1; the pressure safety valve 2 is installed on the top of the silo body 1, and makes the entire silo body 1 is still sealed, and the pressure safety valve 2 decides whether to open the pressure relief according to the real-time pressure in the warehouse body 1; the protective cover 7 is installed on the top of the warehouse body 1, and can cover the pressure safety valve 2. In other embodiments, the pressure safety valve 2 can also be installed on the side of the bin body 1, and correspondingly, the protective cover 7 is also installed on the side; the dust collector 6 is installed on the ground, and is ventilated with the protective cover 7. The mouth is connected. It works as follows:

[0030] The pressure value that the bin body 1 can withstand is certain, and the signal rece...

Embodiment 4

[0033] The difference from the third embodiment is that the intelligent dust collection system described in the second embodiment is applied to the powder silo, such as Figure 4 shown. The pressure safety valve 2 is installed on the bin body 1, and the pressure value that the bin body 1 can withstand is certain. As the powder in the bin body 1 of the powder bin increases, the real-time pressure in the bin body 1 increases. When the real-time pressure value When the pressure value that the bin body 1 can withstand is exceeded, in order to prevent the bin body 1 from being damaged, the pressure safety valve 2 must push against the bin body 1 to release the pressure. circuit is connected, such as Figure 5 As shown, the dust collector 6 starts to work; as the dust in the bin body 1 emerges, the real-time pressure value in the bin body 1 gradually decreases. When the real-time pressure value decreases to the point that the bin body 1 can withstand, the pressure safety valve 2 i...

Abstract

The invention relates to the field of engineering machinery, in particular to an intelligent dust collection system and a filler bin of the intelligent dust collection system applying the intelligent dust collection system. The invention aims to start a dust collection machine for clearing dust when a pressure safety valve pushes open for decompression. The invention has the following technical schemes that the intelligent dust collection system comprises the pressure safety valve, a pressure detecting unit, a control unit and the dust collection machine which are sequentially connected; the pressure detecting unit is used for detecting a real-time pressure value of the pressure safety valve; the control unit is used for presetting a pressure value, and is used for receiving the detected real-time pressure value by the pressure detecting unit, after comparing the real-time pressure value detected by the pressure detecting unit with the preset pressure value, the dust collection machine is controlled to start and stop, due to decompression of the pressure safety valve, meanwhile the surrounding dust is collected by the dust collection machine, thus failure of the safety valve caused by dust can be avoided, and the filler bin can further be prevented from being damaged.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an intelligent dust collection system and a powder silo applying the same. Background technique [0002] During the use of the powder silo of the mixing station, a pressure safety valve must be installed for safe use. The function of the pressure safety valve of the powder bin of the mixing station is: when the pressure in the powder bin reaches the preset value, the pressure safety valve will open to release the excessive pressure in the powder bin to prevent damage to the powder bin. If the pressure safety valve cannot be opened under the set pressure or the set pressure is too high, the weak part of the top of the powder silo will be deformed and damaged due to the excessive pressure in the powder silo. At present, the powder silo of the mixing station usually uses a spring-type pressure safety valve device, which has the following disadvantages: [0003] 1. Because the ...
