[0002] As a basic chemical raw material, food additive and pharmaceutical product, baking soda has a wide range of applications. In baking soda production and processing, heavy alkali is alkali-treated in the alkali-treatment tank and then sent to the wet decomposition tower. After being heated by low-pressure steam, the heavy alkali is decomposed into sodium carbonate solution, and then sent to the carbonization tower for carbonization reaction to produce baking soda.

[0003] When tons of alkali raw materials are put into the alkali-making tank for alkali-making, a large amount of dust will be generated. Workers who come into direct contact with the dust may suffer skin and eye burns and other injuries. Generally, a purification and collection device is set at the feed port of the alkali-making tank. However, the purification device installed in the existing alkali-making tank cannot effectively collect the irritating dust and recycle the materials, causing serious environmental pollution and waste of raw materials.

An inverted insertion port 12 is provided in the feed port 11 above the alkali-making tank body 1, that is, a funnel-shaped design with an opening facing downward, which can reduce the leakage of dust through the feed port 11. A collection box 14 is provided around the outer peripheral side wall of the feed port 11. The collection box 14 is connected to the feed port 11 through air holes 13. The air holes 13 are arranged on the outer wall of the feed port 11 at equal intervals. The dust collection device includes a box body 4, a bag dust collector 3 and a dust suppression tank. The collection box 14 is connected to the air pipe 21, and the air pipe 21 is connected to the vacuum cleaner 2. The vacuum cleaner 2 is connected to the air inlet of the bag dust collector 3. When the vacuum cleaner 2 is in operation, negative pressure is formed in the collecting box 14. After the raw alkali is added into the alkali-making tank through the feed port 11, the dust enters the collecting box 14 through the air hole 13, and is then introduced into the bag filter 3 through the air pipe 21 and the vacuum cleaner 2 for dust collection, thereby effectively reducing the environmental pollution caused by the leakage of dust during the alkali-making feeding.

[0027] The bag filter 3 is installed above the box body 4, and the discharge port for discharging dust aggregates below it is arranged in the box body 4. The dust reduction tank is installed below the box body 4, and the material discharged from the discharge port enters the inlet 11 above the dust reduction tank through the dividing mechanism. Specifically, the dust reduction tank and the box body 4 are both cylindrical in design. The dividing mechanism includes a dividing block 41 and a guide plate 42. The dividing block 41 is a conical design with the tip pointing upward. The dividing block 41 is fixedly installed on the top of the dust reduction tank and corresponds to the discharge port of the bag filter 3. And the guide plate 42 is arranged circumferentially around the dividing block 41 and is fixedly installed downwardly between the inner wall of the box body 4 and the inlet 11. The inlet 11 is opened around the upper side wall of the dust reduction tank corresponding to the guide plate 42. And the guide plate 42 is also circular in design, so that the guide plate 42 is a bucket-shaped design fixedly connected to the inlet 11. When the bag filter 3 is cleaning, the collected dust is discharged from the discharge port. The material can be evenly guided to the surroundings of the material dividing block 41 through the guiding and dividing of the material dividing block 41, and the material passes downward through the material guiding plate 42 and enters the dust reduction tank from the inlet 50 of the dust reduction tank. The material dividing and guiding of the material dividing block 41 and the material guiding plate 42 make the material entering the dust reduction tank looser and the material discharge more even, thereby avoiding blockage caused by material accumulation.

[0028] The material distribution mechanism also includes a vibrator 43, which is installed inside the material distribution block 41 and at the bottom of the material guide plate 42, and can effectively avoid material accumulation on the material distribution block 41 and the material guide plate 42, prevent material blockage, and promote material transportation.
