Description

Technical Field

[0001] The utility model relates to the field of dust collectors, and more specifically, to an improved air box type bag filter. Background Technique

[0002] In places with large amounts of dust such as factories, air filtration is required, and filtration is usually achieved through a bag filter. The bag filter mainly consists of a box body, filter bags, an air inlet, an air outlet, a dust cleaning device, a pressure relief device, etc. During use, gas enters the interior of the box body from the air inlet, passes through the interior of the filter bags, and the dust in the gas can be filtered out through the filter bags. Then, the filter bags are cleaned by the dust cleaning device. After using for a period of time, the dust inside the box body is cleaned out.

[0003] When cleaning the dust in the box body, the entire dust collector needs to be stopped first, then the bolts on the bottom sealing plate of the box body are removed, and then the sealing plate is taken off, so that the dust inside the box body can be cleaned out. The whole process requires the dust collector to be stopped to clean the dust. After the dust collector is stopped, the normal air filtration will be affected, and it can only be used again after the dust in the dust collector is cleaned. During this process, the normal operation of factories, etc. will be affected. Therefore, we propose an improved air box type bag filter to solve the above problems. Content of the Utility Model

[0027] Please refer to Figures 1 - 5, An improved air box type bag filter, including a dust collector body 1. A dropping port is provided at the bottom of the dust collector body 1. A collection assembly 2 is provided at the dropping port at the bottom of the dust collector. The collection assembly 2 includes a housing 3 fixed to the bottom of the dropping port of the dust collector body 1. A first feed port 4 is provided at the top of the housing 3. The first feed port 4 is located below the dropping port. A discharge port 5 is provided at the bottom of the housing 3. A collection cylinder 6 is rotatably connected inside the housing 3. A sealing ring is inlaid on the inner wall of the housing 3 to improve the sealing between the collection cylinder 6 and the housing 3. One side of the collection cylinder 6 penetrates through the housing 3 movably. A second feed port 11 is provided on the circumferential surface of the collection cylinder 6. When the collection cylinder 6 collects dust, the second feed port 11 faces the first feed port 4. When the collection cylinder 6 discharges materials, the second feed port 11 faces the discharge port 5. A connecting rod 7 penetrates through the side of the housing 3 movably. The end of the connecting rod 7 is fixed to the end of the collection cylinder 6. A handwheel 9 is fixed to the end of the connecting rod 7 away from the collection cylinder 6. By providing the handwheel 9, the handwheel 9 can increase the contact area with the hand and the lever arm during rotation, and it is more labor-saving when the handwheel 9 drives the connecting rod 7 to rotate.

[0028] Please refer to Figure 3 , A circular tube 8 is fixed to the side of the housing 3 close to the handwheel 9. The circular tube 8 is movably sleeved on the surface of the connecting rod 7. By providing the circular tube 8, the circular tube 8 can guide the connecting rod 7, so that the connecting rod 7 rotates stably during the rotation process and avoids shaking of the connecting rod 7.

[0029] Please refer to Figure 3 , A fixing bolt 10 is threadedly connected to the circumferential surface of the circular tube 8. The end of the fixing bolt 10 abuts against the circumferential surface of the connecting rod 7. By providing the fixing bolt 10, after the fixing bolt 10 abuts against the connecting rod 7, it can prevent the collection cylinder 6 connected to the end of the connecting rod 7 from rotating during use, and make the collection cylinder 6 more stable during use.

[0030] Please refer to Figure 3 , A circular pad is fixed to the bottom of the fixing bolt 10. The bottom of the circular pad abuts against the surface of the connecting rod 7. The circular pad is a rubber pad. By providing the circular pad, the friction with the connecting rod 7 can be increased. It can avoid hard contact between the fixing bolt 10 and the connecting rod 7, and has a protective effect on the connecting rod 7. And anti-slip stripes are provided at the bottom of the circular pad. By providing the anti-slip stripes, the friction with the connecting rod 7 can be further improved, and it can avoid rotation between the fixing bolt 10 and the connecting rod 7 after fixation, and improve the stability during use.

[0031] Please refer to Figure 5 , A perspective window 12 is inlaid at the end of the collection cylinder 6, and the user can observe the situation inside the collection cylinder 6 from the perspective window 12.

[0032] Please refer to Figure 5, the top of the perspective window 12 is set to be pointed. A contrast marking block 13 is provided on the side of the outer shell 3 close to the perspective window 12. The contrast marking block 13 is located above the pointed position of the perspective window 12. The perspective window 12 is made of transparent acrylic board. During use, the situation inside the collection cylinder 6 can be observed through the perspective window 12 to avoid the situation of too much dust accumulation inside the collection cylinder 6. The bottom of the contrast marking block 13 is also set to be pointed. The pointed bottom of the contrast marking block 13 corresponds to the pointed top of the perspective window 12. When the two are aligned in a straight line, it means that the collection cylinder 6 has rotated to the standard position.

[0033] Working principle: During the daily use of the dust collector body 1, dust will fall downward. The dust will fall from the feed port 4 of the outer shell 3 to the position of the feed port 11 and then fall into the interior of the collection cylinder 6 from the feed port 11. The situation of the collection inside the collection cylinder 6 can be directly understood through the perspective window 12. When the collection inside the collection cylinder 6 is almost full, the mechanism fixing bolt 10 is unscrewed, and the fixing bolt 10 will move away from the surface of the connecting rod 7. Then, hold the surface of the handwheel 9 and rotate the handwheel 9. The handwheel 9 will drive the connecting rod 7 to rotate, and the connecting rod 7 will drive the collection cylinder 6 to rotate. The collection cylinder 6 will rotate inside the outer shell 3. When the collection cylinder 6 rotates 180 degrees, the feed port 11 of the collection cylinder 6 will face the ground. At this time, the dust inside the collection cylinder 6 will fall out. After the dust inside the collection cylinder 6 has fallen out, rotate the collection cylinder 6 by 180 degrees again, and check whether the pointed position of the perspective window 12 points to the position of the contrast marking block 13. If it points to the position of the contrast marking block 13, it means that the rotation of the collection cylinder 6 is completed; otherwise, the collection cylinder 6 has not rotated to the standard position. Finally, tighten the fixing bolt 10 again.
