[0002] The limestone powder consumed by the absorption tower in the electrolytic aluminum process is transported to the workshop by tank trucks. The discharge pipe of the tank truck is connected to the feed pipe of the limestone powder silo. The limestone powder in the tank truck is continuously input into the powder silo for storage through pneumatic transportation by the tank truck. The limestone powder in the powder silo is then discharged through the discharge pipe. Finally, the limestone powder discharged from the discharge pipe is transported to the absorption tower for reaction utilization.

[0030] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.
[0031] The following is combined with Figure 1 To Attachment Figure 4 And specific embodiments describe the present invention in detail.
[0032] like Figure 1 and Figure 2 As shown, the utility model provides a limestone powder silo pressure relief device, comprising a powder silo body 1, a feed pipe 11 is fixedly connected to the top of the powder silo body 1, and the feed pipe 11 is connected to the inside of the powder silo body 1. A discharge pipe 12 is fixedly connected to the bottom of the powder silo body 1, and the discharge pipe 12 is fixedly connected to a first solenoid valve 121.
[0033] The top of the powder bin body 1 is fixedly connected with a connecting pipe 2, and one end of the connecting pipe 2 away from the powder bin body 1 is fixedly connected with a negative pressure pipe 3, and the connecting pipe 2 is connected to the inside of the negative pressure pipe 3. The negative pressure pipe 3 is vertically arranged, and the gas flow direction inside the negative pressure pipe 3 is from bottom to top.
[0034] A nozzle 4 is fixedly connected to the inner wall of one side of the negative pressure pipe 3, and the nozzle 4 is placed above the connecting pipe 2. The nozzle 4 is fixedly connected to a water inlet pipe 41, which penetrates the negative pressure pipe 3 and is fixedly connected to the negative pressure pipe 3. The water inlet pipe 41 provides a water source for the nozzle 4, and the nozzle 4 sprays water mist into the negative pressure pipe 3.
[0035] The tank truck pneumatically transports the limestone powder to the inside of the powder silo body 1 through the feed pipe 11, and the limestone powder is stored inside the powder silo body 1. The connecting pipe 2 connects the powder silo body 1 and the negative pressure pipe 3, and the gas inside the powder silo body 1 flows into the negative pressure pipe 3 through the connecting pipe 2, and then is discharged through the negative pressure pipe 3. The water mist adsorbs the limestone powder entering the negative pressure pipe 3, reducing the possibility of the limestone powder being discharged through the negative pressure pipe 3, and the adsorbed limestone powder is collected and reused. The connecting pipe 2 and the negative pressure pipe 3 can timely relieve the pressure of the powder silo body 1, reducing the possibility of danger caused by untimely pressure relief inside the powder silo body 1.
[0036] The connecting pipe 2 is fixedly connected with a second electromagnetic valve 21. When the tank truck delivers limestone powder to the powder silo body 1, the second electromagnetic valve 21 is opened, and the connecting pipe 2 relieves the pressure inside the powder silo body 1. When the tank truck has finished delivering and there is no need to relieve the pressure inside the powder silo body 1, the second electromagnetic valve 21 is closed to reduce the possibility that the limestone powder inside the powder silo body 1 is sucked into the connecting pipe 2.
[0037] When the limestone powder in the powder bin body 1 needs to be discharged from the discharge pipe 12, the first solenoid valve 121 is opened and the limestone powder is discharged through the discharge pipe 12. When the limestone powder in the powder bin body 1 does not need to be discharged from the discharge pipe 12, the first solenoid valve 121 is closed.
[0038] A material collecting box 5 is provided at the bottom of the negative pressure pipe 3, and the limestone powder absorbed by the water mist inside the negative pressure pipe 3 falls into the material collecting box 5 for collection and reuse. Four rollers 51 are fixedly installed at the bottom of the material collecting box 5, and a handle 52 is fixedly connected to the outer wall of one side of the material collecting box 5. When the limestone powder absorbed by the water mist in the material collecting box 5 accumulates to a certain extent, the staff holds the handle 52 and pushes the material collecting box 5 to move, so that the material collecting box 5 is no longer placed under the negative pressure pipe 3, and the materials in the material collecting box 5 are taken out for reuse, and then the material collecting box 5 is placed under the negative pressure pipe 3 to collect the limestone powder absorbed by the water mist.
[0039] The staff holds the handle 52 and pushes the material receiving box 5 to move. During the process of moving the material receiving box 5, the roller 51 rotates, and the roller 51 has the effect of making the staff move the material receiving box 5 more smoothly.

[0041] The gas can pass through the filter 6 , and a small amount of limestone powder that is not absorbed by the water mist is blocked by the filter 6 , and the filter 6 reduces the possibility that the small amount of limestone powder that is not absorbed by the water mist is discharged through the negative pressure pipe 3 .
[0042] After the filter 6 has been used for a period of time, the staff removes the filter 6 from the negative pressure pipe 3, separates the filter 6 from the plug hole 31, and cleans the filter 6 to reduce the possibility that too much limestone powder accumulates on the filter 6 and affects the gas flow in the negative pressure pipe 3. After the filter 6 is cleaned, the filter 6 can be inserted into the plug hole 31.
[0043] The negative pressure pipe 3 is provided with a fixing component 7 on one side of the plug hole 31. When the filter 6 is inserted into the negative pressure pipe 3, the fixing component 7 is connected to the filter 6. The fixing component 7 increases the stability of the filter 6 in the plug hole 31 and reduces the possibility of the filter 6 being separated from the plug hole 31.
[0044] like Figure 3 and Figure 4 As shown, the fixing assembly 7 includes a support plate 71 fixedly connected to the outer wall of the negative pressure pipe 3, and the support plate 71 is placed below the plug hole 31. A fixing plate 72 is fixedly connected to the upper surface of the support plate 71, and a plug groove 721 is downwardly provided on the upper surface of the fixing plate 72, and a baffle 73 is slidably plugged in the plug groove 721.

[0045] Press the baffle 73 downward, the baffle 73 moves downward to compress the spring 74, so that the upper surface of the baffle 73 is lower than the plug hole 31, and the filter 6 is inserted into the plug hole 31, and then the baffle 73 is released, the spring 74 recovers its deformation, and the spring 74 drives the baffle 73 to move upward, and the side of the baffle 73 close to the negative pressure pipe 3 abuts against the side of the filter 6 close to the baffle 73, and the filter 6 can be installed, and the installation process is relatively convenient. The baffle 73 blocks the filter 6, reducing the possibility of the filter 6 and the plug hole 31 being separated.
[0046] When the filter 6 needs to be taken out from the plug hole 31 , the baffle 73 is pressed downward to separate the baffle 73 from the filter 6 , and the filter 6 is taken out from the plug hole 31 . The process of taking out the filter 6 is relatively convenient.
