Description

Technical Field

[0001] The utility model relates to the technical field of dry-wet separation devices, in particular to a chain plate type dry-wet separation device. Background Art

[0002] Currently, mainstream wet-dry separation solutions utilize two types of equipment: screw stacks and belt conveyors. Screw stacks typically utilize dynamic and static ring extrusion for wet-dry separation. This involves placing the material in a working container and extruding it through dynamic and static rings to remove moisture. Belt conveyors typically use a belt conveyor to transport the material and an extruder to remove excess moisture.

[0003] During actual use, there are the following problems: During the operation of the screw stacking machine, in order to prevent the material from being too dry and clogging the discharge port, the squeezing force is generally not too large, and it is not suitable for ultra-low moisture content conditions; when the belt conveyor is used for dry-wet separation, material residues will stick to the equipment. After the dry-wet separation work is completed, the equipment needs to be flushed with water or other solvents, resulting in a waste of resources. Utility Model Content

[0004] The utility model is intended to provide a chain plate type dry-wet separation device, which solves the application problem of dry-wet separation of screw stacking machine and belt conveyor. It is not affected by the extrusion force, is suitable for ultra-low moisture content working conditions, and does not require water or other solvents to flush the equipment, saving resources.

[0005] The basic solution provided by the utility model is: a chain plate type dry-wet separation device, including a driving device, a chain plate group and a roller brush group;

[0006] The driving device includes two driving gears arranged opposite to each other, namely a feed end gear and a discharge end gear;

[0007] The chain plate group is linked and sleeved on the outer peripheral surfaces of the two driving gears to enable the chain plate group to move in a circular manner outside the two driving gears to feed the material; the chain plate group includes a plurality of chain plates arranged side by side and nested, wherein the chain plates are arranged vertically and their lengths extend along the length direction of the driving gears. When the chain plates are away from the driving gears, a micro gap is formed between the chain plates. When the chain plates move to the driving gears, the gap between the chain plates increases under the action of the tooth spacing of the driving gears;

[0008] The roller brush assembly is located beside the discharging end gear and is clearance-matched with the chain plate moved to the discharging end gear for cleaning the chain plate.

[0009] The working principle and advantages of the utility model are: when the device is used for feeding, the chain plate group moves in a circular motion under the drive of the driving device, and the path of the circular movement includes an upper ring straight section, arc sections on both sides and a lower ring straight section. The upper ring straight section is used for feeding, and under the action of the external extrusion equipment, the material will be squeezed and spread flat on the plane formed by the chain plate, and at the same time, the excess water contained in the material will flow out through the micro gaps between the chain plates, and this section completes the dry and wet separation of the material; it moves into the arc section at the gear at the discharging end, and the dry material on the chain plate plane falls and is discharged. At the same time, under the action of the gear spacing and the nested setting of the chain plates, the gap between the chain plates becomes larger, and the inside of the chain plate is cleaned by the roller brush, and some material residues that fall into the gap between the chain plates are cleaned, thereby improving the discharge and preventing the material from being blocked between the chain plates; after discharging, the chain plate moves to the lower ring straight section, the arc section at the gear at the feeding end, and returns to the upper ring straight section to start the next stage of feeding.

[0010] Compared with the existing technology, this solution adopts a completely different method of using chain plates from the existing ones, forming a new feeding method, and realizing the functions of conveyor belt and filter cloth at the same time. The extrusion force it can withstand is several times greater than that of the common screw stacking machines on the market. It is very suitable for dry-wet separation conditions of ultra-low moisture content materials. The overall structure of the device is highly integrated and has complex functions, while optimizing the dry-wet separation process. Through the side-by-side nesting and vertical design of the chain plates, the gap between the chain plates changes with the tooth spacing of the drive gear, achieving changes in the feeding and discharging stages. The micro-gap during the feeding stage ensures a tighter plane formed by the chain plates, which facilitates efficient feeding and prevents leakage. At the same time, the tight plane and the vertical design of the chain plates increase the rigidity of the entire chain plate assembly and can withstand greater extrusion pressure. This eliminates the need to consider the moisture content of the material at the discharge port to prevent discharge failure, resulting in a lower moisture content after treatment, making it suitable for ultra-low moisture content conditions. Furthermore, the micro-gap acts as a filter cloth in the belt-type dry-wet separator, reducing the use of filter cloth and the need to use large amounts of liquid to rinse the filter cloth to remove material residue, thus reducing equipment maintenance and saving costs. The larger gap during the discharging stage, in conjunction with the roller brush, helps improve the discharge rate and eliminates the need for water or liquid flushing, thus conserving water resources. Furthermore, compared with the spiral extrusion of a screw press, the chain plates of this device, which are connected in series, do not suffer from significant mechanical wear, saving significant maintenance costs and making it suitable for promotional use in dry-wet separation processes.

[0018] The following is a further detailed description through specific implementation methods:

[0019] The marks in the drawings of the specification include: feed belt 1, pressure cylinder 2, chain plate 3, chain plate connecting bolt 31, small boss 32, drive motor 4, drive gear 5, feed end gear 51, discharge end gear 52, roller brush 6, water guide trough 7, discharge belt 8, support wheel 9.

[0020] The embodiment is basically as shown in the attached Figure 1 and Figure 2 Shown: A chain plate type dry-wet separation device, including a driving device, a chain plate group and a roller brush group.

[0021] The driving device includes two driving gears 5 arranged opposite to each other, namely a feed end gear 51 and a discharge end gear 52; and also includes a driving motor 4. In this embodiment, it is arranged at the feed end gear 51, which is beneficial to the layout of the device. Under the action of the driving motor 4, the driving gear 5 rotates.

[0022] The chain plate group is linked and sleeved on the outer circumference of the two driving gears 5 to form an arc-connected rectangular conveyor belt to achieve the circular movement of the chain plate group outside the two driving gears 5 (such as Figure 2 The circular movement path includes the upper ring straight segment, the arc segments on both sides and the lower ring straight segment. When the chain plate 3 is located in the upper ring straight segment, feeding is performed, and the chain plate 3 moves to the arc segment at the discharge end gear 52 for discharging. After passing through the lower ring straight segment and the arc segment at the feed end gear 51, it returns to the upper ring straight segment for the next stage of feeding.

[0023] The chain plate group includes a plurality of chain plates 3 arranged side by side and nested. Specifically, Figure 3 (a) and (b) are composed of two types of chain plates, and the chain plates are connected by multiple chain plate connecting bolts 31. The four chain plates are connected in the following way: Figure 4As shown, the side-by-side nesting method is as follows Figure 5 As shown, this forms Figure 2 The entire chain plate group is shown; the chain plate group and the inner sides of the two drive gears 5 are formed with a plurality of protrusions having a spacing, which are used to cooperate with the drive gear 5.

[0024] The chain plate 3 is arranged vertically, and its length extends along the length direction of the driving gear 5. The small end faces of the chain plate 3 are closely arranged side by side to form a conveyor belt plane. When the chain plate 3 is away from the driving gear 5 (that is, when it moves to the upper ring straight section and the lower ring straight section), a micro gap is formed between the chain plates 3. The micro gap is generally 0.4-0.6mm, and can be preferably 0.5mm, to ensure the tightness of the plane, efficient feeding, and normal water filtration; when the chain plate 3 moves to the driving gear 5 (that is, two arc segments), under the action of the tooth spacing of the driving gear 5 and the nested connection mode of the chain plates, the gap between the chain plates 3 increases for discharging.

[0025] The top of the chain plate 3 is processed with a small lateral boss 32, such as Figure 6 The small square shape shown is the small boss 32 located at the left and right edges of the top of the chain plate, which ensures that the chain plates 3 are parallel to each other and flat with the running plane when running in a straight section.

[0026] like Figure 7 As shown, the driving gear 5 has a multi-section structure, which is adapted to the protrusions of the chain plate group. Specifically, the multiple teeth on the driving gear 5 are adapted according to the position and length of the chain plate connecting bolt 31 to ensure that the teeth can accurately push the connection of the chain plate 3, and the chain plate 3 can be guaranteed to run smoothly when the equipment is running.

[0027] The roller brush assembly is located beside the discharging end gear 52 and is clearance-matched with the chain plate 3 moved to the discharging end gear 52 for cleaning the chain plate 3 .

[0028] Specifically, in this embodiment, the roller brush group includes a plurality of roller brushes 6 arranged along the length direction of the discharge end drive gear 5. In this embodiment, there are 3 of them, ensuring that the entire length of the chain plate 3 can be covered to achieve an efficient cleaning effect; the plurality of roller brushes 6 are arranged perpendicular to the discharge end drive gear 5 with an axis, and the bristles on the roller brushes 6 are also evenly arranged along the axis of the roller brush 6 to improve the cleaning effect.

[0029] The device also includes a support wheel 9, which is located between the two driving gears 5 and on the inner side of the chain plate group, and is used to support the chain plate group to ensure that the chain plate 3 will not be crushed by the pressing cylinder 2 during the transmission process; the length of the support wheel 9 extends along the length direction of the driving gear 5, and the length is not less than the chain plate 3, so as to achieve the purpose of effective support; in this embodiment, 3 support wheels 9 are provided, which can provide efficient support for the chain plate group of conventional length, and at the same time help to improve the stiffness of the chain plate group, so that the device is adapted to more ultra-low moisture content working conditions.

[0030] The device also includes several pressing cylinders 2, positioned above the two drive gears 5 and the chain plate assembly. These cylinders are spaced apart from the chain plate assembly, which moves below the pressing cylinders 2, to squeeze the material. The specific force of the pressing cylinders 2 depends on the operating conditions. Due to the increased rigidity of the chain assembly in this solution, the pressing force of the pressing cylinders 2 in this system can be 1-10 MPa compared to existing equipment, significantly exceeding the 0.1-0.3 MPa of common commercially available screw stacks. Consequently, materials with an ultra-low moisture content of 10-40% can be obtained.

[0031] The device further comprises a feed belt 1 and a discharge belt 8, wherein the feed belt 1 is located above the feed end drive gear 5 and the chain plate group, and the discharge belt 8 is located below the discharge end drive gear 5 and the chain plate group. Figure 2 As shown, the discharge port of the feed belt 1 is aligned with the first three chain plates located in the straight section of the upper ring to ensure that the material is effectively delivered to the chain plate 3, and to prevent the material from falling directly from the larger gap between the chain plates 3 in the arc section of the feed end gear 51; along the direction from the discharge end gear 52 to the feed end gear 51, the feed port of the discharge belt 8 exceeds the discharge end gear 52, to ensure that when the gap between the chain plates 3 at the discharge end gear 52 becomes larger, the discharge material can be efficiently collected, and dry material can be prevented from falling outside the discharge belt 8.

[0032] like Figure 2 As shown, the device also includes a water guide trough 7, which is located below the two drive gears 5 and the chain plate group, and above the discharge belt. The water guide trough 7 has an inclination angle of 1-5°, preferably 1.5°. The height of the water guide trough 7 on the side of the drive gear 5 at the discharge end is greater than the height on the side of the drive gear 5 at the feed end, which helps to quickly discharge excess water. The water guide trough 7 is located at one end on the side of the drive gear 5 at the discharge end, and is actually located at the front side of the arc section (away from the direction of the roller brush group). After extrusion, the dry material is transferred by the chain plate group and falls into the discharge belt 8. Because the water guide trough 7 is located at the front side of the arc section, a large amount of material will not fall off the chain plate from here and fall into the water guide trough, ensuring that the material falls into the discharge belt 8.

[0033] When using, such as Figure 2 As shown, through the driving device, driven by the driving gear 5, the chain plate group is Figure 2It moves in a circular manner in the direction indicated by the arrow, and runs smoothly. The straight section of the upper ring forms a plane with a micro-gap. The gap between the chain plates in the arc section normally becomes larger, and the roller brush 6 starts. Its bristles can fit with the surface of the chain plate 3 moved to the gear 52 at the discharge end. After the chain group and the roller brush 6 run in accordance with the above requirements, the feed belt 1 starts to discharge the material, and the wet material moves from the side of the straight section of the upper ring close to the feed end to the discharge end. The pressing cylinder 2 located above the chain plate group grinds the material under the action of the corresponding control system, and the material is squeezed and spread onto the plane. The chain plates are densely arranged to form a plane, which will not cause a large amount of material to fall from the gap. At the same time, the excess moisture contained in the material is squeezed out and will pass through The material flows out from the micro gaps between the chain plates 3. The chain plates 3 here play the role of the belt and filter cloth in the traditional belt filter press at the same time, completing the dry and wet separation of the material in the upper ring straight section to form dry material; the chain plates move the dry material into the arc section at the discharge end gear 52, and the dry material on the plane of the chain plates 3 falls and is discharged to the discharge belt 8. At the same time, under the effect of the gear spacing and the nested setting of the chain plates, the gaps between the chain plates 3 become larger, and the roller brush 6 is used to clean the inside of the chain plates 3, and some of the material residues that fall into the gaps between the chain plates 3 are cleaned and enter the discharge belt 8; after discharging, the chain plates move to the lower ring straight section, the arc section at the feed end gear 51, and then return to the upper ring straight section to start the next stage of feeding.

[0034] The present embodiment provides a chain-type wet-dry separation device that proposes a completely different method of using chain plates than the existing ones. The device has a highly integrated structure and multiple functions, while also optimizing the wet-dry separation process. Through the side-by-side nesting and vertical design of the chain plates, the gap between the chain plates changes with the tooth spacing of the drive gear, achieving changes in the feeding and discharging stages. The micro-gap in the feeding stage ensures a tighter plane formed by the chain plates, which is conducive to efficient feeding and avoids leakage. At the same time, the tight plane and the vertical design of the chain plates increase the rigidity of the entire chain plate assembly and can withstand greater extrusion pressure, resulting in a lower moisture content of the material after processing. There is no need to consider the moisture content of the material at the discharge port to prevent discharge failure, making it suitable for ultra-low moisture content conditions. Furthermore, the micro-gap acts as a filter cloth in a belt-type wet-dry separator, reducing the use of filter cloth and eliminating the need to use large amounts of liquid to rinse the filter cloth to clean material residue, thereby reducing equipment maintenance processes and saving costs. The larger gap in the discharging stage, in conjunction with the roller brush, is conducive to improving the discharge rate and does not require water or liquid for flushing, thus saving water resources. In addition, compared with the spiral extrusion of the screw stacking machine, the chain plates connected in series in this device have no obvious mechanical wear, saving a lot of maintenance costs, and are suitable for promotion and use in dry-wet separation processing.
