Description

Technical Field

[0001] The utility model belongs to the field of baking soda production equipment, and specifically relates to a vacuum feeder for baking soda production. Background Art

[0002] The vacuum feeder uses vacuum suction to transfer granular or powdered materials. The vacuum feeder is often used for material transportation in the production process of baking soda. The materials transported by the vacuum feeder are granular or powdered. As the vacuum feeder suction operation time increases, it is easy to get blocked because more and more particles are adsorbed on the dust filter device, resulting in the particles not being blown out during backblowing. When the existing vacuum feeder breathing device is blocked, it needs to be shut down and the dust filter cover of the dust filter device needs to be removed and cleaned, which is not only time-consuming and labor-intensive, but also seriously affects production operations. Utility Model Content

[0003] In order to address the deficiencies in the prior art, the utility model aims to provide a vacuum loader for baking soda production. The device can effectively clean the dust filter cover without repeatedly stopping the machine to disassemble and install the dust filter cover, thereby significantly improving the baking soda production efficiency.

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0022] like Figure 1-4As shown, the utility model proposes a vacuum feeder for baking soda production, including a feeder body 1, a vacuum generator 11 and a back-blowing device 12, wherein the vacuum generator 11 and the back-blowing device 12 are mounted on the top of the feeder body 1, and a first anti-blocking vibrator 31 is mounted at the mouth of the feed pipe 15 of the feeder body 1. A second anti-blocking vibrator 32 is mounted on the outer wall of the discharge port 14 of the feeder body 1. By setting two anti-blocking vibrators, the accumulated materials at the feed pipe 15 and the discharge port 14 of the feeder can be effectively dispersed and dredged, thereby playing an effective anti-blocking role.

[0023] A partition 13 is horizontally installed on the upper part of the vacuum loader, and a rotating ring 131 is installed at the air port 130 opened on the partition 13. A cylindrical dust filter cover 7 with an upper opening is detachably installed below the rotating ring 131. The dust filter cover 7 can be connected to the rotating ring 131 through a flange structure 71, thereby realizing a detachable connection of the dust filter cover 7, making it convenient to disassemble and repair the dust filter cover 7.

[0024] An annular brush 5 is provided on the outer sleeve of the dust filter cover 7, and the annular brush 5 abuts against the dust filter cover 7. Specifically, the annular brush 5 includes an annular plate 51 and a brush 52. The annular plate 51 is coaxially movably provided outside the dust filter cover 7, and the brush 52 is installed on the inner wall of the annular plate 51 and slides against the outer wall of the dust filter cover 7. When the dust filter cover 7 rotates, the brush 52 can abut against the outer wall of the dust filter cover 7 to brush dust, and at the same time, the up and down movement of the annular plate 51 can drive the brush 52 to abut against the outer wall of the dust filter cover 7 and move up and down, so as to have a better effect in cleaning accumulated dust.

[0025] The feeder body 1 is also provided with a driving mechanism that simultaneously drives the dust filter cover 7 to rotate and the annular plate 51 to rise and fall. The driving mechanism includes a cylinder 2, a rotating shaft 22, a connecting rod 4 and a driving motor 21. The cylinder 2 is vertically fixedly mounted on the top of the feeder body 1, and the rotating shaft 22 is coaxially rotatably mounted in the cylinder 2. The upper end of the rotating shaft 22 penetrates the cylinder 2 and is connected to the output shaft of the driving motor 21. The lower end of the rotating shaft 22 is fixedly connected to the bottom center of the dust filter cover 7, and the rotating energy of the rotating shaft 22 drives the dust filter cover 7 to rotate synchronously. A rotating cylinder 221 is coaxially fixed on the rotating shaft 22 in the cylinder body 2, and two arc-shaped guide plates 2211 are fixedly arranged along the outer wall of the circumference of the rotating cylinder 221 and are inclined upward. There are two connecting rods 4 in the cylinder body 2 that are symmetrically arranged on the left and right, and the connecting rod 4 is vertically slidably installed in the cylinder body 2. Specifically, a limit plate is horizontally fixed in the cylinder body 2 above the rotating cylinder 221, and a through hole is penetrated on the limit plate. Two connecting rods 4 are vertically slidably penetrated in the through holes. The connecting rod 4 can slide up and down in the through holes, which effectively limits its movement and improves the movement stability of the connecting rod 4.

[0026] The middle of the two connecting rods 4 are fixed with corresponding guide blocks 42, which are slidably supported on the guide plate 2211. The lower end of the connecting rod 4 extending out of the cylinder 2 movably passes through the partition 13 and is fixedly connected to the annular plate 51. The upper end of the connecting rod 4 is horizontally fixedly connected with a connecting plate 41, and a spring 6 is installed between the connecting plate 41 and the inner top of the cylinder 2. The rotating shaft 22 movably passes through the middle of the limit plate and the connecting plate 41. When the rotating shaft 22 drives the rotating drum 221 to rotate, under the guiding support of the two guide plates 2211, the two connecting rods 4 will be lifted vertically upward through the guide block 42, and the spring 6 will be compressed. When the guide block 42 moves to the uppermost end of the guide plate 2211, as the rotating drum 221 continues to rotate, under the elastic force of the spring 6, the guide block 42 will fall from the guide plate 2211, so that the connecting plate 41 abuts against the limit plate, limiting the falling of the connecting rod 4 and the guide block 42, and then completing the reset of the connecting rod 4, the guide block 42, and the connecting plate 41. As the rotating drum 221 continues to rotate, the guide plate 2211 will abut against the guide block 42 again, and reciprocate in sequence, so that the connecting rod 4 drives the lower annular brush 5 to reciprocate up and down, and the dust accumulated on the rotating dust filter cover 7 can be effectively cleaned.

[0027] When the utility model is used, when the vacuum loader conveys materials, the driving motor 21 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the dust filter 7 to rotate synchronously. At the same time, the rotating shaft 22 also drives the rotating drum 221 and the guide plate 2211 to rotate. Through the cooperation of the guide block 42, the connecting rod 4, the connecting plate 41 and the spring 6 and other structures, the connecting rod 4 drives the annular brush 5 to abut against the outer wall of the dust filter 7 and move up and down, so that the dust accumulated on the rotating dust filter 7 can be effectively cleaned without repeatedly stopping the machine to disassemble and assemble the dust filter 7, thereby significantly improving the production efficiency of baking soda.
