[0002] Dry powder processing refers to the process of converting raw materials into powdered materials through a series of physical or chemical treatments. This processing method is widely used in many fields, including powder metallurgy, dry powder mortar production, etc.

[0003] After the existing high-pressure air flow pulverizer for dry powder has completed pulverizing the dry powder, it is necessary to intercept the larger particles therein through a filter screen, and then the qualified particles are transported through the filter screen, and the intercepted particles will be crushed for a second time to facilitate a higher qualified rate of dry powder. When filtering the dry powder, the filter screen is more likely to be clogged due to powder with high humidity. At this time, the filter screen needs to be disassembled and cleaned in time to facilitate normal filtration of the filter screen. However, in the prior art, when disassembling the filter screen for cleaning, it is mostly necessary to remove the screws used for fixing them separately before they can be removed, which is relatively cumbersome and will reduce the work efficiency of the staff.

[0021] Reference Figure 1 - Figure 3 As shown, the utility model provides a technical solution: a high-pressure airflow pulverizer for dry powder, comprising a pulverizer body 1, a motor 2 is installed at the top of the pulverizer body 1, a discharge pipe 3 is installed on the left side of the pulverizer body 1, a feed pipe 4 is installed on the right side of the pulverizer body 1, a feed hopper 5 is installed on the top of the feed pipe 4, a replacement groove 6 is opened at the top of the discharge pipe 3, a filter screen 7 is slidably connected inside the replacement groove 6, a fixed block 8 is fixed at the top of the discharge pipe 3, a fixed rod 9 is fixed at one end of the fixed block 8 close to the filter screen 7, an adjusting rod 10 is slidably connected inside the fixed rod 9, a fixed groove 25 used in conjunction with the adjusting rod 10 is opened at one end of the filter screen 7 close to the adjusting rod 10, a pop-up groove 11 is opened at the top of the fixed rod 9, and a filter screen 7 is slidably connected inside the fixed rod 9. A pressing groove 12 is provided, and an elastic spring 13 is installed inside the pressing groove 12. A pressing block 14 is fixed on the top of the elastic spring 13. The inside of the pressing groove 12 is slidably connected with the pressing block 14. When the staff needs to replace the filter 7, the pressing block 14 is pressed inwardly to drive the elastic spring 13 to store force, and at the same time, the adjusting rod 10 is released from the limit. At this time, the adjusting rod 10 is moved out of the fixed groove 25 to release the limit of the filter 7. At this time, the filter 7 is replaced. After completion, the adjusting rod 10 is slid into the fixed groove 25, and the pressing block 14 is aligned with the pop-up groove 11. The elastic force of the elastic spring 13 drives the pressing block 14 to pop out quickly, so that the adjusting rod 10 is limited, thereby achieving rapid replacement of the filter 7 when it is blocked, thereby improving the work efficiency of the staff.

[0022] Reference Figure 2As shown, in the present embodiment: a limiting plate 15 is fixed at the top of the discharge pipe 3, there are two limiting plates 15 and a first slide groove 16 is provided at one end close to the filter screen 7, a first slider 17 is fixed at the front and rear ends of the filter screen 7, the interior of the first slide groove 16 is slidably connected to the first slider 17, and through the setting of the first slide groove 16 and the first slider 17, the filter screen 7 can form a guiding effect during the replacement process, so that it can slide into the replacement groove 6 more conveniently, thereby improving the replacement efficiency of the filter screen 7.

[0023] Reference Figure 3 As shown, in the present embodiment: a second slide groove 26 is provided at the front end and the rear end inside the pressing groove 12, a second slider 18 is fixed at the front end and the rear end of the pressing block 14, and the interior of the second slide groove 26 is slidably connected to the second slider 18. By setting the second slide groove 26 and the second slider 18, when the adjusting rod 10 needs to be fixed, it can effectively prevent the elastic spring 13 from causing the pressing block 14 to pop out excessively, causing the pressing block 14 to pop out from the pop-up groove 11, thereby affecting the normal fixation of the adjusting rod 10.

[0024] Reference Figure 4 As shown, in the present embodiment: a third slide groove 19 is provided at the front end and the rear end inside the fixed rod 9, a third slider 20 is fixed at the front end and the rear end of the adjusting rod 10, and the interior of the third slide groove 19 is slidably connected to the third slider 20. By setting the third slide groove 19 and the third slider 20, the adjusting rod 10 can move more stably inside the fixed rod 9, preventing the adjusting rod 10 from being offset and unable to slide into the fixed groove 25, thereby improving the stability of the device when in use.

[0025] Reference Figure 4 As shown, in this embodiment: a return spring 21 is fixed to the end of the adjusting rod 10 close to the fixed block 8, and the end of the return spring 21 away from the adjusting rod 10 is fixed to the inside of the fixed rod 9. Through the setting of the return spring 21, when the filter 7 needs to be replaced, the adjusting rod 10 is released from the limit. At this time, the return spring 21 drives the adjusting rod 10 to rebound quickly from the fixed groove 25, so that the filter 7 is released from the limit, thereby further improving the replacement efficiency of the filter 7.

[0026] Reference Figure 2 As shown, in this embodiment: a sealing plate 22 is installed on the surface of the discharge pipe 3, and the size of the sealing plate 22 is adapted to the replacement groove 6. Through the setting of the sealing plate 22, the dry powder can be effectively prevented from leaking during the discharge process, thereby improving the sealing performance during the discharge.

[0027] Reference Figure 5As shown, in this embodiment: a contact plate 23 is installed at the top of the feed pipe 4, and a vibration mechanism 24 is installed at the top of the contact plate 23. Through the arrangement of the contact plate 23 and the vibration mechanism 24, when dry powder is blocked in the feed pipe 4, the vibration mechanism 24 is started to make the contact plate 23 drive the feed pipe 4 to vibrate, so that the blocked dry powder is cleared, thereby achieving effective anti-blockage when the dry powder is discharged.

[0028] When the filter screen 7 is replaced, the staff member presses the pressing block 14 inwardly to drive the elastic spring 13 to store force and release the limit of the adjusting rod 10. At this time, the adjusting rod 10 is moved out of the fixing groove 25 to release the limit of the filter screen 7. At this time, the filter screen 7 is replaced. After completion, the adjusting rod 10 is slid into the fixing groove 25 and the pressing block 14 is aligned with the pop-up groove 11. The elastic force of the elastic spring 13 drives the pressing block 14 to pop out quickly, so that the adjusting rod 10 is limited, thereby achieving rapid replacement of the filter screen 7 when it is blocked, improving the work efficiency of the staff. Through the arrangement of the first slide groove 16 and the first slide block 17, the filter screen 7 can form a guiding effect during the replacement process, so that it can slide into the replacement groove 6 more conveniently, thereby improving the replacement efficiency of the filter screen 7. Through the arrangement of the second slide groove 26 and the second slide block 18, when the adjusting rod 10 needs to be fixed, it can effectively prevent the elastic spring 13 from driving the pressing block 14 to pop out excessively, causing the pressing block 14 to pop out from the pop-up groove The third sliding groove 19 and the third sliding block 20 can make the adjusting rod 10 move more stably inside the fixing rod 9, and prevent the adjusting rod 10 from being offset and unable to slide into the fixing groove 25, thereby improving the stability of the lifting device when in use. By setting the reset spring 21, when the filter screen 7 needs to be replaced, the adjusting rod 10 is released from the limit. At this time, the reset spring 21 drives the adjusting rod 10 to rebound quickly from the fixing groove 25, so that the filter screen 7 is released from the limit, thereby further improving the replacement efficiency of the filter screen 7. By setting the sealing plate 22, the dry powder can be effectively prevented from leaking during the discharging process, thereby improving the sealing performance during the discharging. By setting the contact plate 23 and the vibration mechanism 24, when the dry powder is blocked in the feeding pipe 4, the vibration mechanism 24 is started to make the contact plate 23 drive the feeding pipe 4 to vibrate, so that the blocked dry powder is dredged, thereby achieving effective anti-blocking when the dry powder is discharged.
