The negative pressure device 4 works to suck the pigment dust generated in the mixing chamber 1 into the collecting pipe 601. The pigment dust enters the mixing chamber 1 through the collecting pipe 601 and is intercepted in the collecting box 501. A shaking filter cloth 604 is installed on the inner side of the collecting pipe 601. The pigment is preliminarily intercepted by the filter cloth 604 to avoid pigment waste.

[0024] Reference Figure 1 The mixing bin 1 includes a bin body 101 and a discharge valve 102 . The discharge valve 102 is installed at the lower end of the bin body 101 . The mixed pigment is discharged through the discharge valve 102 . The collecting pipe 601 connects the bin body 101 with the collecting box 501 .

[0025] Reference Figure 2The stirring assembly 2 includes a stirring shaft 202 rotatably mounted inside the bin body 101. The upper end of the stirring shaft 202 passes through the bin body 101 and is connected to a driving motor 201 through a coupling. The stirring shaft 202 is driven to rotate by the driving motor 201 to stir the inorganic pigment in the bin body 101. The feeding bin 3 includes a silo 301 mounted on the bin body 101. A silo cover 302 is mounted on the top of the silo 301. A ventilation groove is mounted on the silo cover 302 to keep the air pressure in the bin body 101 stable. A filter screen 303 is mounted in the ventilation groove to intercept dust in the air flow through the filter screen 303 to prevent the dust from affecting the purity of the pigment.

[0026] Reference Figure 3 The negative pressure device 4 includes an air pump 401 installed on the mixing bin 1, and an air guide pipe 402 is connected to the air inlet end of the air pump 401. The end of the air guide pipe 402 is connected to the side of the collecting box 501. A detachable filter element 502 is installed between the air guide pipe 402 and the collecting pipe 601 in the collecting box 501. A funnel-shaped guide groove is installed at the bottom of the end of the collecting box 501 close to the collecting pipe 601, and a reflux valve 503 is installed at the lower end of the guide groove.

The air pump 401 is used to evacuate air to introduce the pigment dust into the collecting box 501, and the dust is intercepted by the filter element 502. Most of the dust falls into the funnel-shaped guide groove. The reflux valve 503 is opened at a fixed time to discharge the dust into the bin body 101 to avoid waste.

[0027] Reference Figure 3 A bracket 602 is installed on the inner side of the collecting pipe 601, and a filter cloth frame 603 is installed on the lower end of the bracket 602. The filter cloth 604 is fixed on the inner side of the filter cloth frame 603. A plurality of springs 605 are installed on the lower end of the bracket 602. The lower ends of a plurality of guide rods 606 pass through the filter cloth frame 603 and are slidably connected with the filter cloth frame 603. A plurality of springs 605 are slidably sleeved on the guide rods 606. The springs 605 are located between the bracket 602 and the filter cloth frame 603. When air flows through the filter cloth 604, a thrust is applied to the filter cloth 604 to move the filter cloth frame 603, so that the filter cloth frame 603 slides along the guide rods 606, compressing the springs 605 and causing the filter cloth 604 to shake.

[0028] The implementation principle of the inorganic pigment mixing and dust removal equipment in the embodiment of the present application is as follows:

[0029] First, the inorganic pigment is added into the silo 301 by opening the silo cover 302 on the silo 301. After the addition is completed, the silo cover 302 is closed, and then the driving motor 201 is started to drive the stirring shaft 202 to rotate in the silo body 101 through the coupling to mix and stir the inorganic pigment to achieve uniform mixing of the pigment. When the inorganic pigment in the silo body 101 is stirred, a certain amount of pigment dust is generated. At this time, the air pump 401 is started to suck the air and dust into the collection box 501 through the air guide pipe 402 and the collection pipe 601. The dust first passes through the collection pipe 601 and contacts the filter cloth 604. Due to the effect of the airflow, the filter cloth 604 It will be subjected to thrust and generate shaking through the cooperation of spring 605 and guide rod 606. This shaking helps to shake off the pigment particles trapped on the filter cloth to prevent blockage and further intercept dust. The airflow and remaining dust after preliminary interception enter the collection box 501. The filter element 502 performs secondary filtration on the dust in the airflow and retains the dust in the collection box 501. When the stirring is completed, the uniformly mixed inorganic pigment is discharged from the bin body 101 by operating the unloading valve 102. At the same time, the reflux valve 503 can be opened at regular intervals to discharge the pigment dust collected at the bottom of the collection box 501 back into the bin body 101 through the reflux port to avoid waste.
