[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0029] It should be further noted that the drawings and embodiments of the present invention mainly describe and explain the concept of the present invention. On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can adopt well-known methods to implement the above specific forms and settings.

[0030] When an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0031] The orientation terms "inside" and "outside" refer to the inside and outside relative to the contour of each component itself. The orientation or positional relationships indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or positional relationships shown in the drawings. This is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0032] For the convenience of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above or over other devices or structures" will then be positioned "below or under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways, and corresponding interpretations are made for the spatial relative descriptions used here.

[0033] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, and "several" means one or more, unless otherwise specifically defined.

[0034] Now, the horizontal curtain construction waste slurry and wastewater treatment system provided by the present invention will be described.

[0035] As Figures 1 to 3As shown in the figure, an embodiment of the present invention provides a treatment system for waste slurry and wastewater in horizontal curtain construction, including a sedimentation tank 1, a filtration tank 2 connected to the sedimentation tank 1, and a purification tank 3 connected to the filtration tank 2. An inlet 21 is provided at the top of the filtration tank 2. A filtration cylinder 4 that seals the bottom of the inlet 21 is horizontally rotatably connected inside the filtration tank 2. The filtration cylinder 4 is used for solid-liquid separation. A collection port 41 is axially opened on one side of the filtration cylinder 4 along its own axis. A driving mechanism 5 for driving the filtration cylinder 4 to rotate reciprocally is provided on the filtration tank 2. The position of the collection port 41 is always not lower than the axis of the filtration cylinder 4. The filtration cylinder 4 is detachably installed in the filtration tank 2 through a disassembly mechanism 6. When the filtration cylinder 4 is in the state of filtration operation, the collection port 41 and the inlet 21 are in a separated state.

[0036] Specifically, in this embodiment, an activated carbon layer is provided in the purification tank 3. The filtered wastewater is pumped into the purification tank 3 and discharged after being adsorbed and purified by the activated carbon layer. The filtration cylinder 4 can be made of hard filtration materials such as porous ceramic filter materials, resin-based composite filter materials, or porous plastic filter materials.

[0037] The treatment system for waste slurry and wastewater in horizontal curtain construction provided in this embodiment, compared with the prior art, improves the treatment effect of waste slurry and wastewater by sequentially sedimenting, filtering, and purifying the waste slurry and wastewater. After the waste slurry and wastewater enter the filtration tank 2 through the inlet 21, they first pass through the outside of the filtration cylinder 4 for primary filtration. The solids remain on the outside of the filtration cylinder 4, and the liquid enters the inside of the filtration cylinder 4 and then passes through the inside of the filtration cylinder 4 for secondary filtration. The liquid after secondary filtration is at the bottom of the filtration tank 2 and is pumped into the purification tank 3.

[0038] After filtering for a period of time, the driving mechanism 5 drives the filtration cylinder 4 to rotate, so that the collection port 41 on the side of the filtration cylinder 4 is communicated with the inlet 21. At this time, the solids remaining on the outside of the filtration cylinder 4 are scraped to the inside of the filtration cylinder 4 by the bottom of the inlet 21 for collection. The filtration cylinder 4 continues to rotate so that the outside of the filtration cylinder 4 on the other side of the collection port 41 faces the inlet 21. After filtering for a period of time, the filtration cylinder 4 rotates in reverse, and so on. It can realize filtering the waste slurry and wastewater at different positions on both sides of the collection port 41 of the filtration cylinder 4, and the filtered solids can automatically enter the filtration cylinder 4 for collection. The position of the collection port 41 is always not lower than the axis of the filtration cylinder 4, which can ensure that the solids in the filtration cylinder 4 will not fall into the filtration tank 2. When the inside of the filtration cylinder 4 needs to be cleaned, it can be removed and cleaned through the disassembly mechanism 6, greatly reducing the manual cleaning frequency, improving the continuity of the solid-liquid separation operation, and thus improving the treatment efficiency of the waste slurry and wastewater.

[0039] As Figure 4 shown, a specific embodiment provided by the present invention on the basis of the above embodiment is as follows:

[0040] The driving mechanism 5 includes a rotating shaft 51, a cage gear 52, a driving motor 53, an incomplete gear 54 and a limiting component 55; the rotating shaft 51 is rotatably arranged outside the filtering box 2 and is coaxially fixed to the filtering cylinder 4, and there are two cage gears 52 which are coaxially fixed on the rotating shaft 51; the driving motor 53 is horizontally installed outside the filtering box 2 and is perpendicular to the rotating shaft 51; the incomplete gear 54 is coaxially fixed on the output shaft of the driving motor 53, and the incomplete gear 54 is used to engage with the two cage gears 52 separately and not simultaneously; the limiting component 55 is arranged outside the filtering box 2 and is used to limit the rotation angle of the rotating shaft 51. When the rotating shaft 51 is within this limited angle, the position of the collection port 41 is always not lower than the axis of the filtering cylinder 4.

[0041] When the filtering cylinder 4 needs to rotate, start the driving motor 53 to drive the incomplete gear 54 to rotate unidirectionally. The incomplete gear 54 engages with one of the cage gears 52 and drives it to rotate, so that the rotating shaft 51 and the filtering cylinder 4 rotate; when the filtering cylinder 4 needs to rotate in the reverse direction again, the driving motor 53 continues to drive the incomplete gear 54 to rotate in the same direction. The incomplete gear 54 engages with the other cage gear 52 and drives it to rotate in the opposite direction, so as to realize the reverse rotation of the rotating shaft 51 and the filtering cylinder 4. The driving motor 53 can use a unidirectional rotation motor to realize the reciprocating rotation of the filtering cylinder 4, which reduces the cost and ensures the rotation effect of the filtering cylinder 4.

[0042] As Figures 4 to 5 shown, a specific embodiment provided by the present invention on the basis of the above embodiment is as follows:

[0043] The limiting component 55 includes a rotating plate 551 and two limiting plates 552. The rotating plate 551 is fixed on one side of the rotating shaft 51, and the two limiting plates 552 are fixed outside the filtering box 2 and are located on both sides of the rotating plate 551. The limiting plates 552 are used to limit the rotation angle of the rotating plate 551; a positioning mechanism 7 is arranged between the rotating plate 551 and the limiting plates 552, and the positioning mechanism 7 is used to fix the rotating plate 551 at the corresponding limiting plate 552. At this time, the filtering cylinder 4 is in the state of filtering operation.

[0044] The two limiting plates 552 can limit the rotation angle of the rotating plate 551 to ensure the normal working state of the filtering cylinder 4, avoid the sediment leaking out downward from the collection port 41 due to excessive rotation angle, and thus improve the filtering stability of solid-liquid separation.

[0045] As Figures 4 to 5 shown, a specific embodiment provided by the present invention on the basis of the above embodiment is as follows:

[0046] The positioning mechanism 7 includes an arc-shaped plate 71, arc-shaped ratchet teeth 72, a moving frame 73, a ratchet pawl 74, and a driving member 75. There are two arc-shaped plates 71, which are fixed on both sides of the rotating plate 551, and the arc-shaped plate 71 is coaxially arranged with the rotating shaft 51; there are two arc-shaped ratchet teeth 72 coaxially fixed on the corresponding arc-shaped plate 71, and the tooth directions of the two arc-shaped ratchet teeth 72 are opposite; the moving frame 73 is horizontally slidably arranged outside the filter box 2, and there are two ratchet pawls 74 arranged on the moving frame 73. The ratchet pawl 74 is used to engage with the corresponding arc-shaped ratchet teeth 72, and the two ratchet pawls 74 and the corresponding arc-shaped ratchet teeth 72 are not engaged simultaneously; the driving member 75 is arranged outside the filter box 2 and is connected to the moving frame 73. The driving member 75 is used to drive the moving frame 73 to slide, so that different ratchet pawls 74 engage with the corresponding arc-shaped ratchet teeth 72.

[0047] Specifically, in this embodiment, when the rotating shaft 51 drives the two arc-shaped plates 71 to rotate towards the left, the arc-shaped ratchet teeth 72 and the ratchet pawl 74 on the left are in an engaged state, and the arc-shaped ratchet teeth 72 and the ratchet pawl 74 on the right are in a separated state; when the rotating plate 551 rotates to fit with the left limiting plate 552, the arc-shaped ratchet teeth 72 and the ratchet pawl 74 on the left perform reverse restriction on it, thereby realizing the fixed state of the rotating shaft 51 and the filter cylinder 4.

[0048] When it is necessary to rotate the filter cylinder 4 to the right, first drive the moving frame 73 to move through the driving member 75, so that the left ratchet pawl 74 is separated from the arc-shaped ratchet teeth 72, and at the same time the right ratchet pawl 74 engages with the arc-shaped ratchet teeth 72. At this time, the driving motor 53 continues to drive the incomplete gear 54 to rotate, and the rotating shaft 51 and the filter cylinder 4 can be rotated to the right until the rotating plate 551 fits and is fixed with the right limiting plate 552, which not only improves the operation stability after the rotation of the filter cylinder 4 is completed, but also improves the switching efficiency of the rotation of the filter cylinder 4 in different directions.

[0049] As Figure 4 shown, a specific implementation manner further provided by the present invention on the basis of the above implementation manner is as follows:

[0050] The driving member 75 is a cylinder. The main body of the driving member 75 is installed on the outer wing plate of the filter box 2, and the piston rod of the driving member 75 is connected to the moving frame 73.

[0051] The cylinder as the driving member 75 has the characteristics of fast response speed and stable driving force. When it is necessary to change the engagement state of the ratchet pawl 74 and the arc-shaped ratchet teeth 72, the cylinder can quickly and accurately drive the moving frame 73 to slide, thereby realizing the quick fixation or release of the position of the rotating plate 551 and improving the working efficiency of the entire positioning mechanism 7.

[0052] As Figure 2 、 Figure 6 and Figure 7 shown, a specific implementation manner further provided by the present invention on the basis of the above implementation manner is as follows:

[0053] The filter box 2 is horizontally cut into two halves along the axis of the rotating shaft 51; the disassembly mechanism 6 includes a mounting plate 61, a plug plate 62, a connecting plate 63, a pressing block 64 and a power assembly 65. The mounting plate 61 is fixed on both sides of the two halves of the filter box 2 and is arranged in an up-and-down fitting manner. There are a plurality of connecting plates 63 that penetrate the up-and-down fitting mounting plates 61, and the connecting plates 63 on the same set of mounting plates 61 are arranged in a row; the pressing block 64 is slidably arranged on the lower surface of the lower mounting plate 61 and corresponds to the connecting plate 63 one by one. A jack 631 for inserting the corresponding pressing block 64 is provided on the side of the connecting plate 63; the power assembly 65 is arranged on the lower mounting plate 61, and the power assembly 65 is used to drive a row of pressing blocks 64 to be inserted into the corresponding jacks 631 at the same time.

[0054] When it is necessary to disassemble the filter cartridge 4 for cleaning, the power assembly 65 drives all the pressing blocks 64 to disengage from the jacks 631. After removing the connecting plate 63 and the plug plate 62, and then removing the upper half of the filter box 2, the filter cartridge 4 can be directly taken out for cleaning.

[0055] When it is necessary to install the filter cartridge 4, first place the filter cartridge 4 into the filter cartridge 4 and adjust it to a specified angle, then fasten the upper half of the filter box 2 so that the corresponding mounting plates 61 are in an up-and-down fitting state, penetrate the connecting plate 63 and a row of plug plates 62 through the mounting plates 61, and drive a row of pressing blocks 64 to be inserted into the jacks 631 at the same time through the power assembly 65, and then the installation of the filter cartridge 4 and the filter box 2 can be completed, finally improving the disassembly and assembly efficiency of the filter cartridge 4.

[0056] Such as Figure 7 and Figure 8 shown, a specific implementation manner provided by the present invention on the basis of the above-mentioned implementation manner is as follows:

[0057] The lower surface of the pressing block 64 is inclined, and the inner bottom wall of the jack 631 is an inclined surface or an arc surface adapted to the lower surface of the pressing block 64. When the pressing block 64 is inserted into the jack 631, it presses the plug plate 62 downward; an elastic layer 632 is provided on the lower surface of the connecting plate 63.

[0058] When the power assembly 65 drives the pressing block 64 to be inserted into the jack 631, the inclined surface of the pressing block 64 gradually presses the inclined surface or the arc surface in the jack 631, so that the plug plate 62 drives the connecting plate 63 to press the elastic layer 632 downward, improving the firmness between the two mounting plates 61, and further improving the operating stability of the filter cartridge 4 and the filter box 2.

[0059] Such as Figures 6 to 7 shown, a specific implementation manner provided by the present invention on the basis of the above-mentioned implementation manner is as follows:

[0060] The power assembly 65 includes side plates 651, a screw rod 652, and a power member 653. The side plates 651 are fixed to both ends of the lower mounting plate 61. The screw rod 652 is rotatably connected to the two side plates 651. A row of plug plates 62 are all threadedly connected to the screw rod 652. The power member 653 is connected to the screw rod 652 and is used to drive the screw rod 652 to rotate.

[0061] Further, the power member 653 is a handwheel or a motor for driving the screw rod 652 to rotate, and manual or electric drive can be selected according to the actual situation. In this embodiment, a handwheel is specifically adopted.

[0062] After the plug plates 62 penetrate through the two mounting plates 61, the power member 653 drives the screw rod 652 to rotate. The screw rod 652 simultaneously drives a row of plug plates 62 to insert into the corresponding jacks 631, realizing the driving function of a row of extrusion blocks 64 in a limited space, and the structure is simple, easy to install and maintain.

[0063] As Figure 7 shown, a specific implementation manner further provided by the present invention on the basis of the above implementation manner is as follows:

[0064] The power assembly 65 further includes a locking nut 654. The locking nut 654 is threadedly connected to the screw rod 652. The locking nut 654 is used to press against the side plate 651 to fix the screw rod 652.

[0065] After the screw rod 652 rotates to a proper position, the side plate 651 is pressed against by the locking nut 654, which can prevent the screw rod 652 from loosening due to vibration or other external force factors, ensuring the structural stability of the power assembly 65, thereby ensuring the structural stability of the filter box 2 and being beneficial to the stable operation of the entire filtration system.
