[0002] The dust suppression device for quartz sand shaping is a device used to control the spread of dust during the crushing and shaping of quartz sand. This device effectively collects and suppresses the dust generated during the production process, reduces environmental pollution and improves working conditions. It can efficiently separate particulate matter in the airflow to ensure that emissions meet standards. Its design needs to take into account the air volume, dust removal efficiency and energy consumption. It is suitable for quartz sand processing lines to ensure safe production and environmental compliance.

[0003] Chinese Patent Publication No. CN219518293U discloses a dust suppression device for quartz sand crushing, including a housing. Inside the housing, below the filter chamber, spray pipes and filter plates are arranged in sequence. The filter plates filter the spray water, and the filtered spray water is pumped back to the spray pipes by a water pump, realizing water recycling. The main spray pipe on the dust suppression device can rotate under the drive mechanism, achieving uniform spraying and effectively improving the dust suppression effect. The filter cotton in the filter chamber of the dust suppression device can be easily replaced, improving work efficiency.

[0004] In the dust suppression process of the aforementioned patented dust suppression device, the contact between gas and liquid is not very tight, and due to the spray dead zone, some gas cannot be completely suppressed and is discharged outside the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a dust suppression device for quartz sand shaping. The device filters the flue gas transmitted through the inlet pipe using filter cotton. The filtered flue gas is then sent into the liquid stored at the lower end of the outer shell. The liquid fully contacts the flue gas, causing the particles in the flue gas to be retained in the liquid, thereby achieving dust suppression during quartz sand shaping and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for quartz sand shaping, comprising a shell, a filter screen horizontally arranged in the middle of the shell, a transmission pipe penetrating through the middle of the filter screen, and diversion pipes sealed and connected to the transmission pipes on both sides of the lower end of the shell. The liquid level stored in the lower end of the shell is higher than the filter screen. Stirring blades are provided at the lower ends of the two diversion pipes. A filter frame is provided at the upper end of the shell, and a return pipe is provided on one side of the outer side of the shell.

[0007] Preferably, the filter frame has grids arranged longitudinally inside, and filter cotton is filled between two adjacent grids.

[0008] Preferably, the upper end of the outer shell is provided with an air inlet pipe, and the air inlet pipe, filter frame and transmission pipe are sequentially and sealed together.

[0009] Preferably, the two ends of the return pipe are sealed to the upper end and the lower end of the filter screen, respectively, and a pump is provided in the middle of the return pipe.

[0010] Preferably, the pump draws liquid from the upper part of the filter screen through the return pipe.

[0011] Preferably, a second baffle is provided at the front end of the filter frame, and the two sides of the second baffle are fixedly connected to the filter frame by bolts.

[0012] Preferably, a first baffle is provided at the front end of the outer shell, and the first baffle is fixedly connected to the outer shell by bolts, and an air outlet is provided on the other side of the inner shell.

[0013] Preferably, the lower end of the outer casing is provided with a motor whose output shaft is fixedly connected to the lower end of the stirring blade.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, when extracting the flue gas generated during the shaping of quartz sand, the flue gas passes through the filter cotton inside the filter frame, then passes through the filter screen and is diverted by the diversion pipe and sent into the liquid at the lower end of the outer shell. With the liquid being stirred by the stirring plate, the flue gas fully contacts the liquid stored at the lower end of the outer shell, causing the particles in the flue gas to be retained at the lower end of the outer shell. Finally, the flue gas after dust suppression can be discharged through the outlet. The flue gas is directly sent into the liquid used for dust suppression, so that the flue gas can fully contact the liquid, without creating dead zones, and without causing some flue gas to fail to be dusted, thus improving the dust suppression effect of the flue gas.

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] like Figure 1 As shown, a dust suppression device for quartz sand shaping in this embodiment includes a housing 1, a filter screen 9 is horizontally arranged in the middle of the housing 1, a transmission pipe 8 is provided through the middle of the filter screen 9, and the liquid that comes into contact with the flue gas is pre-poured out and stored in the lower end of the housing 1.

[0022] The liquid level stored inside the lower part of the outer casing 1 is higher than that of the filter screen 9;

[0023] In order to ensure that the gas transmitted inside the transmission pipe 8 can be evenly distributed in the lower part of the shell 1, a diversion pipe 12 is provided on both sides of the lower part of the shell 1. Both diversion pipes 12 are sealed to the lower part of the transmission pipe 8. After the flue gas transmitted through the transmission pipe 8 is diverted by the diversion pipes 12, the flue gas can be evenly distributed in the lower part of the shell 1.

[0024] In addition, such as Figure 3 As shown, the lower ends of the two diversion pipes 12 are provided with stirring blades 13, and the lower end of the outer shell 1 is provided with a motor whose output shaft is fixedly connected to the lower end of the stirring blades 13. The output of the motor to the stirring blades 13 can agitate the liquid stored inside the outer shell 1, and the agitation can also improve the tightness of the contact between the liquid and the flue gas.

[0025] To filter the flue gas fed into the transmission pipe 8, a filter frame 7 is provided at the upper end of the inner shell 1. The filter frame 7 has longitudinally arranged grids 10 inside, with filter cotton 11 filling the spaces between adjacent grids 10. An air inlet pipe 2 is provided at the upper end of the outer shell 1, and the air inlet pipe 2, filter frame 7, and transmission pipe 8 are sequentially and sealed together. The extracted flue gas is fed into the filter frame 7 through the air inlet pipe 2. After entering the filter frame 7, the flue gas is filtered layer by layer by the filter cotton 11. The filtered flue gas is then fed into the liquid stored at the lower end of the inner shell 1.

[0026] A return pipe 3 is provided on one side of the outer casing 1. The two ends of the return pipe 3 are sealed and connected to the upper end and the lower end of the filter screen 9, respectively. A pump 14 is provided in the middle of the return pipe 3. The pump 14 can draw the liquid at the upper end of the filter screen 9 through the return pipe 3 and send it to the lower end of the filter screen 9. The pump 14 can draw the liquid with dust to actively contact and pass through the filter screen 9, and actively filter the stored liquid. The pump 14 draws the liquid at the upper end of the filter screen 9 through the return pipe 3.

[0027] like Figure 2As shown, a second baffle 6 is provided at the front end of the filter frame 7, and the two sides of the second baffle 6 and the filter frame 7 are fixedly connected by bolts. After the second baffle 6 covers the front end of the filter frame 7, it can restrict the filter cotton 11 inside the filter frame 7 and also restrict the transmitted flue gas, so that the flue gas can flow toward the transmission pipe 8 and finally be discharged from the position of the diversion pipe 12.

[0028] A first baffle 4 is provided at the front end of the outer shell 1, and the first baffle 4 is fixedly connected to the outer shell 1 by bolts. The first baffle 4 can be removed by unscrewing the bolts corresponding to the first baffle 4, and the filter screen 9 and the filter frame 7 for preliminary liquid filtration inside the outer shell 1 can be exposed.

[0029] In order to discharge the flue gas passing through the filter screen 9, an air outlet 5 is provided on the other side of the inner shell 1, and the flue gas passing through the filter screen 9 will be discharged directly from the air outlet 5.

[0030] Working principle: When using the device to suppress dust in the flue gas generated during the crushing and shaping of quartz sand, the fan draws the flue gas and sends it into the filter frame 7 through the inlet pipe 2. The flue gas contacts the filter cotton 11 layer by layer and is sent into the transmission pipe 8. The flue gas in the transmission pipe 8 is diverted and discharged by the diversion pipe 12. The flue gas discharged from the diversion pipe 12 directly contacts the liquid stored at the lower end of the inner shell 1. After dust suppression, the liquid passes through the filter screen 9 and is discharged from the outlet 5. The dust in the gas is restricted by the filter screen 9. When the gas is discharged from the diversion pipe 12, the stirring plate 13 is driven by the motor and rotates to stir the liquid stored at the lower end of the inner shell 1, increasing the tightness of the contact between the flue gas and the liquid. On the other hand, during the contact between the flue gas and the liquid, the start of the pump 14 will draw the liquid filtered by the filter screen 9 through the return pipe 3, so that the liquid circulates through the filter screen 9, further increasing the frequency of contact between the liquid and the flue gas and improving the dust suppression effect.
