[0025] See attached document Figures 1 to 3 As shown, this application embodiment provides a settling device, including a main box 1, on which an openable box cover 101 is disposed. An air inlet pipe 2 is introduced from the outside to the inside of the box cover 101 so that the gas to be processed is injected into the main box 1 through the air inlet pipe 2 for gas-solid separation. An exhaust pipe 3 is provided on the box cover 101, and the gas after gas-solid separation is discharged from the exhaust pipe 3.

[0026] As is customary, there are no restrictions on the connection method between the cover 101 and the box body; it can be either a snap-fit ​​connection or a threaded connection.

[0027] like Figure 1As shown, a dust filter assembly 4 is installed inside the main housing 1. The air inlet pipe 2 extends from the top of the main housing 1 to below the dust filter assembly 4. Gas-solid separation is achieved by utilizing the principle of air rising and powder particles sinking. The separated gas is discharged from the exhaust pipe 3. Of course, it is understandable that in order to achieve rapid air circulation in the main housing 1, gas can be introduced into the main housing 1 under high pressure through the air inlet pipe 2, and an exhaust fan can be installed at the exhaust pipe 3 to quickly extract air from the main housing 1. In this way, the mixed gas is injected below the dust filter assembly 4, and the exhaust fan can create a relative negative pressure in the area above the dust filter assembly 4, so that the mixed gas can continuously rise and pass through the dust filter assembly 4, and the dust filter assembly 4 effectively completes the gas-solid separation.

[0028] In one embodiment, to facilitate replacement of the dust filter assembly 4, the dust filter assembly 4 is detachably disposed within the main housing 1. Specifically, as shown below... Figure 1 and Figure 2 As shown, the dust filter assembly 4 includes an inner cylinder 402 and an outer cylinder 401. The inner cylinder 402 is centrally located inside the outer cylinder 401, and the two are spaced apart to form a gap space for installing the filter screen 403. The filter screen 403 is fixedly installed between the inner cylinder 402 and the outer cylinder 401. The filter screen 403 is designed with mesh holes for the purpose of filtering powder particles, and the specific design depends on the size of the solid medium being filtered.

[0029] To enable detachable installation between the dust filter assembly 4 and the main housing 1, such as Figure 1 and Figure 2 As shown, the inner wall of the main housing 1 is circumferentially arrayed with multiple support platforms 5. When installing the dust filter assembly 4, the outer cylinder 401 overlaps the support platform 5. The outer wall of the air inlet pipe 2 is secured with a fixing sleeve 6 by bolts. The outer wall of the fixing sleeve 6 is circumferentially arrayed with multiple slots, arranged from top to bottom and not penetrating through. The inner wall of the inner cylinder 402 is provided with insertion blocks 404 corresponding to each slot. During installation, the inner cylinder 402 is fitted onto the air inlet pipe 2 and the insertion blocks 404 are inserted into the slots. It is easy to imagine that when the dust filter assembly 4 needs to be replaced, first remove the bolts used to install the fixing sleeve 6, remove the fixing sleeve 6 from the air inlet pipe 2, and then remove the inner cylinder 402 from the fixing sleeve 6, thus removing the entire dust filter assembly 4. When replacing the new dust filter assembly 4, first insert the inner cylinder 402 into the slot and assemble it with the fixing sleeve 6 through the insert block 404. Then, put the fixing sleeve 6 on the air inlet pipe 2 and tighten the bolts to complete the installation of the dust filter assembly 4. Then, put the dust filter assembly 4 into the main housing 1 and let the outer cylinder 401 overlap the support platform 5 to complete the installation of the dust filter assembly 4. It is very convenient.

[0030] In this embodiment, as Figure 1 and Figure 3As shown, a baffle box 7 is provided below the dust filter assembly 4. The baffle box 7 is fixed inside the main housing 1 by a support frame 705. An overflow port is provided on the top of the baffle box 7, and the inner diameter of the baffle box 7 gradually decreases from the top to the bottom, forming a narrow opening 702 at the bottom. The air inlet pipe 2 is located at the center of the overflow port. The overflow port is offset from the filter screen 403 of the dust filter assembly 4. A gap is reserved between the filter screen 403 and the baffle box 7 to form an airflow rising channel 701. An inclined dust discharge plate 703 is integrally formed on the side wall of the baffle box 7. A dust falling channel is formed between the dust discharge plate 703 and the main housing 1. As can be imagined, when the mixed gas enters the turbulence box 7 from the intake pipe 2, the inner diameter of the turbulence box 7 gradually decreases from top to bottom, forming a narrow passage 702 at the bottom. The internal channel of the turbulence box 7 becomes smaller, and the gas is forced to overflow from the overflow port. Since the filter screen 403 is offset from the overflow port, when the mixed gas overflows from the overflow port, the mixed gas flows obliquely upward towards the filter screen 403. After being filtered by the filter screen 403, the powder particles are blocked below the filter screen 403 and sink due to gravity. The sinking particles and the rising airflow are offset, and the powder particles will not form a strong collision with the rising airflow during the sinking process, thereby reducing the number of sinking particles that are carried back to the filter screen 403 by the airflow. The falling powder particles fall through the dust collection channel to avoid the rising airflow and fall into the bottom of the main box 1. The bottom of the main box 1 is provided with a discharge port 8, from which the gas is discharged. A solenoid valve 9 is provided at the discharge port 8, and the discharge is carried out by controlling the opening of the solenoid valve 9. Furthermore, it is easy to understand that by setting the spoiler box 7 to a structure with a large opening at the top and a small opening at the bottom 702, some of the powder particles that settle in the spoiler box 7 can fall into the bottom of the main box 1 through the small opening at the bottom 702, thus avoiding the accumulation of powder particles in the spoiler box 7 and making it difficult to clean.

[0031] In one embodiment, the bottom of the main box 1 is a conical box bottom. It can be understood that the conical box bottom can form an inclined surface, and the powder particles can slide down along the inclined surface, which is more conducive to the powder particles falling and being discharged than a flat box bottom.

[0032] In a preferred embodiment, such as Figure 1 As shown, the filter screen 403 is arched and protrudes towards the side of the turbulence box 7. It is easy to imagine that when the filter screen 403 performs gas-solid separation, under the action of airflow pressure, some particles will be blown towards the filter screen 403. Compared with the planar filter screen 403, setting the filter screen 403 as an arched structure can increase the difficulty of powder particles adhering to the arched filter screen to a certain extent. Thus, under the action of airflow, the accumulation of powder particles on the filter screen 403 is reduced, and the powder particles are blown off by the airflow and settle.

[0033] In summary, the settling device provided in this application embodiment achieves effective gas-solid separation by setting a dust filter assembly 4 inside the main housing 1, which filters suspended powder in the air by allowing air to float and pass through the dust filter assembly 4. By setting a turbulence box 7 below the air inlet pipe 2, and using the turbulence box 7 and the dust discharge plate 703 around the box to form independent airflow rising channels 701 and dust discharge channels 704, the rising airflow and the sinking powder are prevented from mixing, thereby effectively achieving gas-solid separation.

[0034] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
