[0033] See also Figure 1 and Figure 2 A dust removal device for a mixing device includes a box body 1, a dust removal cover 2, a plurality of dust removal bags 3, a vortex casing 4 and a motor 5.

[0034] The front side of the box body 1 is open, and a box door 1a is hingedly connected by a hinge connection. Two partitions, one above and one below, are fixedly arranged in the box body 1. The two partitions are marked from top to bottom as: upper partition 1b and lower partition 1c. A lock structure 1a3 can be provided between the box door 1a and the box body 1, and the lock structure 1a3 keeps the box door 1a closed. After the box door 1a is closed, it is matched with the upper partition 1b and the lower partition 1c, and three closed chambers are formed in the box body 1. These three chambers are marked from top to bottom as: upper chamber 1d, middle chamber 1e and lower chamber 1f.

[0035] Here, the term "sealed" means that after the door 1a is closed, the openings of the three chambers and the door 1a are sealed independently. More specifically, the front of the box body 1, the front of the upper partition 1b, and the front of the lower partition 1c are all provided with a first sealing strip 1g, and the three chambers are individually enclosed by the first sealing strip 1g.

[0036] The lower chamber 1f has an air inlet 1f1, the upper chamber 1d has an air outlet 1d1, the lower partition 1c between the chamber and the middle chamber 1e has multiple first connecting holes 1c1, and the upper partition 1b between the middle chamber 1e and the upper chamber 1d has at least one second connecting hole 1b1.

[0037] The dust hood 2 is used for subsequent installation on the stirring device. More specifically, the reactor in the stirring device can be provided with a dust suction port connected to its own inner cavity, and the dust hood 2 can be fixedly connected to the dust suction port by bolts. The dust hood 2 is also connected to the air inlet 1f1 of the housing 1. More specifically, a bellows 2a can be used, and the air inlet 1f1 and the dust hood 2 are provided with extended pipes, and the two ends of the bellows 2a are respectively inserted into the pipes of the air inlet 1f1 and the dust hood 2, and the two ends of the bellows 2a are fastened and fixed by the throat clamp 2b. In addition, the pipe of the air inlet 1f1 can also be provided with a valve, and the air inlet 1f1 can be directly opened and closed by the valve.

[0038] See also Figure 1 and Figure 3 , the dust bag 3 includes a support frame 3a and a bag 3b wrapped around the support frame 3a. Multiple dust bags 3 are sequentially installed in multiple first connecting holes 1c1 of the lower partition 1c to enter the lower chamber 1f. More specifically, the dust bag 3 can pass through the first connecting hole 1c1 from top to bottom and enter the lower chamber 1f; the top of the support frame 3a is larger in size and cannot pass through the first connecting hole 1c1, and remains in the chamber 1e and is installed on the lower partition 1c.

[0039] See also Figure 5 and Figure 6In some embodiments, for each dust bag 3, the support frame 3a can slide up and down relative to the box body 1; the top of the support frame 3a is in the middle chamber 1e, and a spring 3d is arranged between the lower partition 1c; the spring 3d keeps the top of the support frame 3a downward against the lower partition 1c. More specifically, the lower partition 1c can be threaded with a bolt 3c, the screw rod of the bolt 3c has a smooth portion, and the top of the support frame 3a has a through hole that matches this smooth portion, so that the support frame 3a can slide up and down relative to the box body 1; the spring 3d is a compression spring, which is sleeved on this smooth portion, with the upper end against the nut portion of the bolt 3c, and the lower end against the top of the support frame 3a, so that the top of the support frame 3a is kept downward against the lower partition 1c.

[0040] In this way, when there are many dust particles attached to the outer surface of the dust bag 3, you can grab the top of the support frame 3a, manually overcome the effect of the spring 3d, first move the dust bag 3 upward for a while, and then release the top of the support frame 3a. Under the action of the spring 3d and gravity, the dust bag 3 moves downward and resets to the top of the support frame 3a to rest against the lower partition 1c, thereby shaking off the dust particles on the dust bag 3.

[0041] Furthermore, for multiple dust removal bags 3, the tops of the support frames 3a are fixedly connected together, so as to facilitate the above-mentioned operation of shaking off dust particles on all dust removal bags 3 at the same time.

[0042] See also Figure 1 and Figure 3 In some embodiments, the dust removal device of the stirring device further includes a collecting tray 6. The collecting tray 6 is placed in the lower chamber 1f, below the plurality of dust removal bags 3.

[0043] In this way, the dust particles falling from the dust removal bag 3 are collected by the collecting tray 6, and the dust particles in the lower chamber 1f can be easily cleaned by replacing the collecting tray 6.

[0044] See also Figure 7 In some embodiments, the lower partition 1c is detachably connected to the box body 1. Specifically, the lower partition 1c can be pulled out from the box body 1, and the rear side wall, left side wall and right side wall of the lower partition 1c can be provided with a second sealing strip, which is sealed with the corresponding inner wall of the box body 1 after being installed in the box body 1, and the first sealing strip 1g is not provided on the front of the box body 1, the front of the upper partition 1b and the front of the lower partition 1c, but is provided on the box door 1a.

[0045] In this way, after taking out the lower partition plate 1c from the box body 1, the dust removal bag 3 can be cleaned and replaced more conveniently.

[0046] See also Figure 1 and Figure 2The volute 4 is fixed to the upper partition 1b of the housing 1, is in the upper chamber 1d, and covers all the second communicating holes 1b1. In the accompanying drawings, the second communicating hole 1b1 is set to one, that is, the inner diameter of the volute 4 is designed to be larger than the aperture of the second communicating hole 1b1, and the two are coaxial. The volute 4 is also connected to the air outlet 1d1 of the upper chamber 1d. More specifically, the air outlet 1d1 can be set on the side wall of the upper chamber 1d, and the volute 4 is provided with a third communicating hole 4a1, and a pipeline connected to the air outlet 1d1 and the third communicating hole 4a1 is set.

[0047] See also Figure 1 , Figure 2 and Figure 3 , the motor 5 is fixedly connected to the volute 4. More specifically, the volute may include a cylindrical portion 4a fixedly connected to the upper partition 1b and an end cover portion 4b detachably connected to the top opening of the cylindrical portion 4a, and the motor 5 is fixedly connected to the end cover portion 4b. The output shaft of the motor 5 extends into the volute 4 and is fixed with a turbine 5a. The power line of the motor 5 can be led out through a junction box.

[0048] The motor 5 rotates, and under the action of the turbine 5a, the dust particles in the reactor enter the lower chamber 1f together with the air, and the dust particles adhere to the dust bag 3. The air passes through the dust bag 3, passes through the middle chamber 1e, enters the volute, and is discharged from the air outlet 1d1. Considering the heat dissipation of the motor 5 in the upper chamber 1d, a heat dissipation hole 1d2 connected to the upper chamber 1d can be set at the top of the upper chamber 1d.

[0049] See also Figure 4 In some embodiments, a third connecting hole 4a1 is also provided on the volute 4, and the third connecting hole 4a1 here is connected to the upper chamber 1d, and the air outlet 1d1 is provided on the top surface of the casing 1, that is, no pipeline is provided between the third connecting hole 4a1 and the air outlet 1d1, and the heat dissipation hole 1d2 can be used as the air outlet 1d1.

[0050] In this way, the air discharged from the volute 4 enters the upper chamber 1d from the third through hole, leaves the upper chamber 1d from the heat dissipation hole 1d2, and passes through the motor 5, so as to achieve a better heat dissipation effect on the motor 5.

[0051] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the door 1a of the box body 1 includes: a first door 1a1 and a second door 1a2; the first door 1a1 covers the upper chamber 1d and the middle chamber 1e, and the second door 1a2 covers the lower chamber 1f.

[0052] In this way, the second door 1a2 can be opened alone to clean the dust bag 3.
