The embodiment of the application provides a pit mud preparation system, as shown in fig. 1 to 3, which comprises:

the feeding device 100 is used for feeding pit mud through the feeding device 100;

The feed inlet of the granulating device 700 is communicated with the discharge outlet of the first stirring device 600, and the granulating device 700 prepares pit mud into strips;

A third conveying device 800, the feed inlet of which is communicated with the discharge outlet of the granulating device 700;

The second stirring device 900, the feed inlet of which is communicated with the discharge outlet of the third conveying device 800, and the second stirring device 900 is used for stirring the pit mud with water for the second time;

And a forming box 110 communicated with the discharge port of the second stirring device 900, and pit mud formed in the forming box 110.

As shown in fig. 1, in this embodiment, an exemplary embodiment of the feeding device 100 is used for feeding dried pit mud, and the dried pit mud is fed to the first feeding device 200 through the feeding device 100. The dried pit mud is in a block shape and is large in size, and can be put into the feeding device 100 through equipment such as a forklift.

The first material cutting device 200 is used for primarily cutting the dried pit mud with larger size to obtain the dried pit mud in granular or powder form, so as to facilitate infiltration and stirring.

As shown in fig. 1, the second material cutting device 400 is used for performing secondary cutting on the dried pit mud after cutting, so as to increase the uniformity of the grain size of the dried pit mud after cutting. The first conveying device 300 is used for conveying the pit mud from the first material cutting device 200 to the second material cutting device 400, and is arranged between the first material cutting device 200 and the second material cutting device 400.

The first stirring device 600 is used for adding water into the dried pit mud after secondary thinning and stirring. After the dried pit mud is added with water, the pit mud can be soaked, and then the wet and scattered pit mud can be obtained through stirring. The second conveying device 500 is used for conveying the dried pit mud after secondary shredding from the second blanking device 400 to the first stirring device 600, and is arranged between the second blanking device 400 and the first stirring device 600.

As shown in fig. 1, the granulating apparatus 700 is used for preparing the primarily infiltrated and stirred wet pit mud into a strip shape, that is, for re-granulating the wet pit mud. It should be noted that, the pit mud after preliminary infiltration may still have the condition that some pit mud is still drier, infiltration effect is not good, carries out preliminary stirring to pit mud this moment, and the inside of pit mud still has the phenomenon of dry-wet mixing after the stirring. And through carrying out the re-granulation with the pit mud after preliminary stirring, can disperse this dry and wet mixed pit mud again, and in the in-process that will disperse the pit mud again, can make the pit mud mutually separate and realize dispersing in relatively drier position, in order to expose relatively drier position simultaneously.

The second stirring device 900 is used for adding water to the re-granulated pit mud and stirring the pit mud for the second time. Because the pit mud is redispersed and the relatively dry pit mud is exposed, the relatively dry pit mud can be wetted when water is added to the pit mud for secondary infiltration; in other words, after the pit mud is subjected to secondary infiltration, the dry and wet degree of the pit mud is more uniform, and the condition of local overwetting is not easy to occur, so that the secondary infiltration effect of the pit mud can be ensured. Further, in the subsequent secondary stirring process, the dry and wet degree of pit mud is more uniform, so that the secondary stirring effect can be ensured, and the preparation quality of pit mud is further ensured. The third conveying device 800 is used for conveying the re-granulated pit mud from the granulating device 700 to the second stirring device 900, and is arranged between the granulating device 700 and the second stirring device 900.

As shown in fig. 1, the forming box 110 is used for loading pit mud after secondary stirring. After being discharged from the discharge port of the second stirring device 900, the pit mud falls into the forming box 110. Pit mud can be prepared into a desired shape by restraining and pressing the side walls of the forming box 110.

It can be appreciated that the uniformity of pit mud when being finely cut can be improved by carrying out twice blanking on pit mud by the first material cutting device 200 and the second material cutting device 400; the pit mud is stirred by adding water twice through the first stirring device 600 and the second stirring device 900, and re-pelleting is performed between the two water adding stirring through the pelleting device 700, so that the infiltration effect of the pit mud can be improved, the phenomenon of dry-wet mixing of the pit mud after the water adding stirring is avoided, and the stirring effect of the pit mud is ensured; furthermore, the quality of the pit mud can be guaranteed.

Specifically, the granulating apparatus 700 is an extrusion granulator, and includes a granulating head 710, where a plurality of extrusion ports 720 are disposed on the granulating head 710; when pit mud is discharged from the extrusion port 720 due to extrusion, the pit mud is broken into strip-shaped particles under the action of self weight.

As shown in fig. 1 and 2, in the present embodiment, it is exemplarily illustrated that when the granulating apparatus 700 is an extrusion granulator, it may extrude pit mud so as to be discharged from a discharge port of the granulating head 710. The granulation head 710 may be provided in a cylindrical shape and may be provided as a rotator with its axis horizontally disposed while being open at one end and closed at the other end. During discharging, pit mud enters the granulation head 710 from the open end of the granulation head 710 and is pressed to close to the closed end of the granulation head 710. Several extrusion ports 720 may be formed in the side wall of the prilling head 710 and extend through the side wall of the prilling head 710. As pit mud fills the pelletization head 710 and continues to be extruded, pit mud may be discharged from the extrusion port 720. Because pit mud is soaked and stirred for one time and has certain viscosity, the pit mud can be prepared into strips in the discharging process and falls down due to dead weight. When the dead weight of a certain part of pit mud is greater than the binding force between the part of pit mud and the rest part, the part of pit mud is separated from the rest part; in other words, the pit mud is broken under the action of dead weight, so that strip-shaped particles are formed.

When the pit mud is drier, the binding force is smaller, the pit mud is more easily broken, and the broken position is also more easily ensured to be in a drier position; correspondingly, the smaller the grain size of the pit mud after being broken, the more easily the drier position is exposed; furthermore, the smaller particle size is easier for water to enter the inside of the mixer in the secondary infiltration and stirring process, so that the infiltration effect of the mixer is easier to be ensured, and the secondary stirring effect can be further ensured. When the humidity of the pit mud is proper, the pit mud is difficult to disperse due to larger binding force, and the larger the particle size of the pit mud is; further, the larger particle size is less likely to enter water in the secondary infiltration and stirring process, and is less likely to be excessively infiltrated to affect the viscosity.

It can be appreciated that, in this embodiment, by setting the granulating device 700 as an extrusion granulator, and setting the granulating head 710 to discharge pit mud from a plurality of extrusion ports 720 in an extrusion manner, the pit mud is broken under the action of self weight, and the particle size of the pit mud after automatic granulation can be matched according to the dry and wet degree of the pit mud after primary infiltration and stirring, so that the preparation quality of the pit mud can be further improved.

More specifically, the plurality of extrusion orifices 720 have at least two shapes.

As shown in fig. 1 and 2, in the present embodiment, it is exemplarily illustrated that a plurality of extrusion ports 720 are arranged in a row on a sidewall of the prilling head 710, and the extending direction may be an axial direction of the prilling head 710. The extrusion ports 720 may be provided with a plurality of rows, and the extrusion ports 720 of each row may be formed in the same shape, and the extrusion ports 720 of two adjacent rows may be formed in different shapes. The shape of the extrusion port 720 may include a triangle, a rectangle, a trapezoid, a circle, etc., and the present embodiment is described taking four shapes of a triangle, a rectangle, a trapezoid, and a circle as an example.

It will be appreciated that when pit mud is discharged from extrusion port 720, the discharge port may be extruded at different angles or forces due to different types of shapes, so that the strip-shaped particles form outer side surfaces with different sizes, shapes, angles, etc.; for example, a circular extrusion orifice 720 may provide a curved outer side of the pellet, while a triangular extrusion orifice 720 may provide three planes with an included angle of 60 degrees between the outer sides of the pellet. When the strip-shaped particles form the outer side surfaces with different sizes, shapes, angles and the like, the diversity of the particle sizes of the strip-shaped particles is further increased, not only can the adhesion between the strip-shaped particles be effectively avoided, but also the possibility of forming gaps between the strip-shaped particles is increased, and further the pit mud of the strip-shaped particles is conveniently subjected to secondary infiltration.

Specifically, the pit mud preparation system further comprises a water adding device 120, wherein the water adding device 120 is provided with two groups and corresponds to the first stirring device 600 and the second stirring device 900 respectively, the water adding device 120 comprises a water adding pipe 121 and a control valve 122, the water adding pipe 121 is communicated with a water source, the control valve 122 is arranged on the water adding pipe 121, and a water outlet of the water adding pipe 121 is communicated with a feed inlet of the first stirring device 600 or the second stirring device 900.

As shown in fig. 1 and 3, in the present embodiment, two sets of water adding devices 120 are exemplarily illustrated for adding water to the first stirring device 600 and the second stirring device 900, respectively. Wherein the water adding pipe 121 is communicated with a water source, and the water source can be a reservoir and the like, and liquid for preparing pit mud is stored in the reservoir. The water outlet of the water feeding pipe 121 extends to the feed inlets of the first stirring device 600 and the second stirring device 900, and a control valve 122 is arranged at the water outlet, and the opening and closing of the water outlet can be controlled by the control valve 122. When the control valve 122 controls the water outlet of the water adding pipe 121 to be opened, a liquid for preparing pit mud can be instilled into the first stirring device 600. And the control valve 122 is used for controlling the opening and closing time of the water outlet of the water adding pipe 121, so that the water quantity can be regulated. The amount of water to be added when the pit mud is stirred by the first stirring device 600 and the second stirring device 900 may be selected according to actual needs.

It can be appreciated that, in this embodiment, the water adding device 120 is set, and the water adding device 120 is set to be the water adding pipe 121 and the control valve 122, so that water can be conveniently added when the pit mud is stirred by the first stirring device 600 and the second stirring device 900, which is convenient and fast.

Specifically, the pit mud preparation system further comprises a dust removal device 130, the dust removal device 130 comprises a dust removal pipeline 131 and a pulse dust removal mechanism 132, the dust removal pipeline 131 is communicated with the pulse dust removal mechanism 132, and a wind gap 133 which is communicated with the first material cutting device 200 and the second material cutting device 400 is arranged.

As shown in fig. 1, in the present embodiment, the pulse dust removing mechanism 132 is illustratively described as a functional main body of the dust removing device 130, and is used for adsorbing and collecting dust and the like generated during the blanking process of the first blanking device 200 and the second blanking device 400, so as to achieve the purpose of centralized processing. The pulse dust removal mechanism 132 is communicated with the first material cutting device 200 and the second material cutting device 400 through a dust removal pipeline 131, the dust removal pipeline 131 is provided with a wind gap 133 extending to the feeding holes of the first material cutting device 200 and the second material cutting device 400, and the wind gap 133 is used for enabling dust in the material cutting process of the first material cutting device 200 and the second material cutting device 400 to enter the dust removal pipeline 131.

It can be appreciated that, in this embodiment, by setting the dust removing device 130, and extending the air opening 133 of the dust removing pipe 131 of the dust removing device 130 to the first material cutting device 200 and the second material cutting device 400, the environment where dust and the like in the material cutting process of the first material cutting device 200 and the second material cutting device 400 affect the pit mud preparation system can be prevented from being affected, and the production safety of related operators is ensured.

More specifically, the dust removing duct 131 is further provided with a tuyere 133 communicating with the discharge port of the first stirring device 600.

As shown in fig. 1, in the present embodiment, it is exemplarily illustrated that since the second stirring apparatus 900 is configured to stir the re-granulated pit mud with water, the re-granulated pit mud is primarily soaked and stirred; the first stirring device 600 is to stir the dried pit mud which is finely cut twice with water, and the dried pit mud is still granular or powder, so that dust is not easy to generate in the process of stirring with water by the second stirring device 900, and although the dust can be reduced to a certain extent by the liquid in the process of stirring with water by the first stirring device 600, the phenomenon cannot be completely eradicated. In view of this, the tuyere 133 of the dust removing pipe 131 also extends to the feeding port of the first stirring device 600 to adsorb and collect the dust when the twice-cut dried pit mud enters the first stirring device 600.

It can be appreciated that, in this embodiment, the dust raising during the water adding and stirring of the dried pit mud after the secondary cutting by the first stirring device 600 can be reduced by setting the air inlet 133 of the dust removing pipeline 131 at the feeding port of the first stirring device 600, so as to further improve the production environment.

More specifically, the first and second conveying devices 300 and 500 extend in the same direction, and the three tuyeres 133 of the dust removing duct 131 are disposed on the same path.

As shown in fig. 1, in the present embodiment, exemplarily, the extending directions of the first conveying device 300 and the second conveying device 500 are the same and can be understood as: the length direction of the first and second conveyors 300 and 500 may be the first direction, i.e., extend in the first direction, in a top view. In the vertical plane, the first and second conveyors 300 and 500 may be disposed obliquely according to actual needs. The arrangement mode facilitates that the feeding port of the first conveying device 300 is close to the discharging port of the first material cutting device 200, and the two discharging ports of the first conveying device 300 are close to the feeding port of the second material cutting device 400; the second conveyor 500 is similar.

And the dust removing duct 131 may include a first duct 134 and a second duct 135, wherein the first duct 134 may extend in a first direction, and the second duct 135 may be disposed in a first vertical section, and the first direction may intersect with the first vertical section, and may be perpendicular thereto. The first pipe 134 communicates with the second pipe 135, and a communication place may be provided at a middle portion of the first pipe 134. One end of the first pipe 134, which is far from the second pipe 135, is communicated with the pulse dust removing mechanism 132, and three air ports 133 may be respectively provided at both ends and the middle of the second pipe 135, so that the second pipe 135 is communicated with the feed inlets of the first and second material cutting devices 200 and 400 and the first stirring device 600; at this time, all three air openings 133 of the dust removing pipe 131 are located on the second pipe 135, i.e., are disposed on the same path.

It can be understood that, in this embodiment, by setting the three air openings 133 of the dust removing pipe 131 on the same path, the extending path of the dust removing pipe 131 can be simplified, so that the pulse dust removing device 130 can adsorb the dust at the first material cutting device 200, the second material cutting device 400 and the first stirring device 600 in a shorter path; meanwhile, the whole layout of the pit mud preparation system can be more compact.

As shown in fig. 1, in this embodiment, it is exemplarily illustrated that pit mud is in a block shape and has a large size when being fed; the material passing through the first material cutting device 200 and the second material cutting device 400 is granular or powder; the pit mud is re-pelletized into strips after passing through the molding device, so that the conveying device needs to have stronger bearing capacity in the feeding process, and the conveying device needs to be ensured in the process of being conveyed to the second blanking device 400, the first stirring device 600 and the second stirring device 900, so that residues of materials on the conveying device are reduced, and the like. In view of this, the feeding device 100 may be configured as a plate link chain machine, which is not easy to deform due to compression when bearing the pit mud in block shape; the first conveying device 300, the second conveying device 500 and the third conveying device 800 may be belt conveyors, and the conveying belts thereof have better conveying effect on granular or powdery pit mud.

It can be appreciated that, through the reasonable setting to conveyor, this embodiment is convenient for carry the different pit mud of state to appointed functional device department to the functional device carries out further processing to the pit mud.

More specifically, the widths of the first and second conveyors 300 and 500 are greater than the width of the third conveyor 800.
