First, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic can be included in at least one implementation of the utility model. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Next, the present utility model will be described in detail by using structural diagrams, etc., and in the description of the embodiments of the present utility model, for convenience of explanation, the diagrams showing the structure of the dust collection system will not be partially enlarged to general scale, and the diagrams are only examples, which should not limit the scope of protection of the present utility model. In addition, the three-dimensional space of length, width and depth should be included in actual fabrication.

Referring to fig. 1, fig. 1 is a schematic diagram of an overall structure of a dust collection system according to the present utility model. As shown in fig. 1, for ease of understanding, the dust collection system is divided into the following sections: the device comprises a fixing frame 1 for forming a basic frame structure, a storage box 2 for collecting dry dust or wet dust from a dust remover (not shown) and forming a powder mud storage, a slag taking device 3 for taking out the powder mud in the storage box 2 and transferring the powder mud to a slag cake making device 4, and a slag cake making device 4 for squeezing and dewatering the powder mud to make a powder cake.

The basic connection relation of the structure is that the slag taking device 3 and the slag cake making device 4 are arranged on the fixing frame 1, the slag taking device 3 is positioned above one side of the accumulation box 2, a dust remover is arranged above the other side of the accumulation box 2, the slag cake making device 4 is arranged below the rear of the slag taking device 3, dry powder dust or wet dust falls into the accumulation box 2 containing water from the dust remover to become powder mud, the powder mud is drained from the accumulation box 2 by the slag taking device 3 to become powder slag, the powder slag is sent to the slag cake making device 4, and after the powder slag is dehydrated again to become powder cake under the extrusion action, the powder slag falls into a collecting box (not shown) below to be collected and reused. For a clearer understanding of the structure of each device, each device is described below:

1. storage box 2

The slope setting of the above two cases will not lead dry and wet dust into the sweeping working range of the bristles 6 if the degree of the design is too low, and will affect the applicability of the setting of the field if the degree is too high. It should be noted that the storage tank 2 is already filled with water before use. With continued reference to fig. 1 and 2, above the arc area 21 is a working box 5 of the slag extractor 3, which is intended to be more conveniently fed into the working box 5 when the bristles 6 sweep dry and wet dust. And the design of the arc degree of the arc surface area 21 can lead the accumulation box 2 to have no dead angle, thereby being convenient for cleaning the brush head 6.

As shown in fig. 6 to 8, the slag cake making device 4 comprises a working cylinder 9, a first cake pushing rod 10, a cake pushing rod 11, a second cake pushing rod 12, a second motor 13 and a second air cylinder 14, wherein the working cylinder 9 is arranged below a powder mud outlet 17, a blanking port 18 is arranged above the circular wall of the working cylinder 9, and the opening of a funnel 28 is aligned with the blanking port 18. The second motor 13 is fixed on the fixed frame 1, an output shaft of the second motor 13 is connected with the cake pushing rod 11, the cake pushing rod 11 is a screw rod, one end of the screw rod is movably connected with the output shaft of the second motor 13 through a second transmission flexible (not shown), when the second motor 13 is started, the second transmission flexible rotates, the cake pushing rod 11 does not rotate, and the cake pushing rod 11 only performs transverse telescopic motion. The other end of the cake pushing rod 11 is fixedly connected with a first cake pushing rod 10, the first cake pushing rod 10 is inserted into the working cylinder 9 from one end of the working cylinder 9, the diameter of the first cake pushing rod 10 is matched with the inner diameter of the working cylinder 9, a second air cylinder 14 is movably connected to the fixing frame 1 through a first rotating shaft 19, an extending shaft of the second air cylinder 14 is fixedly connected with a second cake pushing rod 12, the second cake pushing rod 12 is inserted into the working cylinder 9 from the other end of the working cylinder 9, and the diameter of the second cake pushing rod 12 is matched with the inner diameter of the working cylinder 9. When the second motor 13 and the second cylinder 14 are started, the second motor 13 pushes the first pancake 10, and the second cylinder 14 pushes the second pancake 12, and at this time, the first pancake 10 and the second pancake 12 squeeze the powder slag in the working cylinder 9 into a cake shape. In a preferred processing embodiment, the coagulant may be sprayed into the powder residue to enhance cake formation, in this manner, effectively avoiding the powder residue becoming dust again due to excessive bagging, transportation, and drying times. When the first cake pushing 10 and the second cake pushing 12 squeeze the powder slag in the working cylinder 9 into a cake, the powder cake needs to be taken out from the working cylinder 9 for collection, so in order to realize automatic blanking (powder cake), a third cylinder 29, a cover 30 and a movable frame (not shown) are further arranged in the cake making device 4, the third cylinder 29 is fixed on the fixed frame 1, an extension shaft of the third cylinder 29 is fixedly connected with the first rotating shaft 19, the movable frame is movably connected with the fixed frame 1 through the first rotating shaft 19, the second cylinder 14 is fixed on the movable frame, when the third cylinder 29 is started, the first rotating shaft 19 drives the movable frame to rotate, the second cylinder 14 rotates, a cylindrical cover 30 covers the extension shaft end of the second cylinder 14, the inner diameter of the cover 30 is the same as the inner diameter of the working cylinder 9, and when the second cake pushing 12 is parallel to the first cake pushing 10, the cover 30 and the working cylinder 9 form a complete cylindrical structure. The projecting shaft of the third cylinder 29 drives the first rotation shaft 19 to rotate by 270 degrees.

The working principle of the structure is as follows:

1. The powder slag falls into the working cylinder 9, the second motor 13 pushes the cake pushing rod 11 to advance, at the moment, the cake pushing rod 11 (screw rod) does not rotate but does elongation movement, the second transmission flexible rotation enables the first cake pushing 10 to squeeze the powder slag towards the second cake pushing 12 through the elongation of the cake pushing rod 11;

The working principle of the dust collection system of the present utility model is described in detail below:

Waste dust (dry dust or wet dust) collected by the dust collector falls into a gradient area 20 of the accumulation box 2 from a dust hopper, finally falls into the bottom of the accumulation box 2 filled with water along with the gradient, at the moment, the waste dust is deposited at the bottom of the accumulation box 2 to form a powder mud shape, when the collected powder mud reaches a certain amount and the powder mud in the accumulation box 2 needs to be cleaned, the first motor 8 is started to enable the brush head 7 to fall, the brush head 6 stretches into the accumulation box 2, the first sensor 26 positions the depth of the brush head 6, and simultaneously the first cylinder 23 is started to enable the stretching shaft to be longest, so that the brush head 7 changes direction along with the position change of the movable supporting plate 15, and at the moment, the brush head 6 is positioned at the bottom of the accumulation box 2; when the bristles 6 are moved back, the projecting shaft of the first cylinder 23 is moved to change the position of the movable supporting plate 15, so that a force is generated to press the bristles 7 downwards, the bristles 6 are pressed against the bottom wall of the storage tank 2, under this operation, the bristles 6 move with the powder sludge collected during the back movement, and then the bristles 7 are lifted up by the first motor 8, the bristles 6 can be always abutted against the bottom of the storage tank 2 or the bottom surface of the engagement plate 22 to ensure that the powder sludge is scraped, when the bristles 6 take out the powder sludge from the storage tank 2, the excessive water falls back into the storage tank 2, the residual powder sludge is directly conveyed to the powder sludge outlet 17 on the rear side wall 16 along the engagement plate 22 along with the bristles 6, the second sensor 27 is used for limiting the lifting position of the bristles 6, when the lifting detection point is reached, the first motor 8 stops working, powder slag falls into the hopper 28 from the powder mud outlet 17 through the guiding function of the hopper 28, and is gathered by the hopper 28, so that the powder slag falls into the blanking port 18 of the lower working cylinder 9 from the opening, after a certain amount of powder slag is accumulated, the second motor 13 is started, the second motor 13 pushes the cake pushing rod 11 to advance, the first cake pushing 10 pushes the powder slag to the second cake pushing 12 direction through the extension of the cake pushing rod 11, the second cylinder 14 is started, and the second cake pushing 12 and the first cake pushing 10 are in telescopic movement, so that the second cake pushing 12 and the first cake pushing 10 are oppositely extruded for 5-10 times, and each time stays for 30-50 minutes to form a cake, and redundant water falls into a box-shaped structure of the lower collecting box bottom in the extrusion process. When the cake making is completed, the third cylinder 29 is started, the output shaft of the third cylinder 29 rotates 270 degrees, so that the second cylinder 14 is turned over under the drive of the first rotating shaft 19, and at the moment, the second cylinder 14, the cover 30 and the second cake pushing device 12 leave the working cylinder 9, so that one end of the working cylinder 9 close to the second cylinder 14 is in an open state, a space is reserved for the falling of the cake, and the cake falls onto the filter screen of the collecting box below from the open opening.

The above process completes the whole operation in the dust collection system.
