[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment. This embodiment provides a sewage treatment device for landscaping projects, as Figure 1 and Figure 2 shown, which includes a mobile carriage 1. The mobile carriage 1 is movably arranged. A towing connecting plate is installed on a short side side wall of the mobile carriage 1. At the same time, towing rollers are installed on both side walls of the mobile carriage 1. Here, the end where the towing connecting plate is installed is defined as the carriage head. The construction staff can detach and dock the towing connecting plate with the trailer tail, and the trailer drives the mobile carriage 1 to move and adjust the position on the construction site. The applicant designs a mobile carriage, which can be movably arranged according to the location of the landscaping construction site and is used as a supporting device. The advantage of this is that there is no need to temporarily excavate a temporary silt storage pool on the construction site, saving construction time and costs.

[0035] In addition, the mobile carriage 1 has a storage space for storing sewage mixed with silt; and a feed hopper 15 is provided on a short side side wall of the upper end surface of the mobile carriage 1. The sewage pump truck is used to pump the sewage from the construction site and drain it into the storage space through the feed hopper 15 to avoid splashing everywhere outside the carriage.

[0036] This embodiment also discloses a water filtering member. The water filtering member has a water filtering cloth 31 laid empty in the storage space. Side baffle cloths 32 extending upward are provided on both long side side walls of the water filtering cloth 31, and a water filtering concave groove is formed. Specifically, the water filtering member further includes two bearing rods 3. Sliders are fixed at both axial ends of the bearing rods 3. Rectangular grooves 11 are opened on opposite side walls of the two long sides of the storage space. Slide rods 33 are horizontally fixed in the rectangular grooves 11. The sliders are located in the rectangular grooves 11, and jacks for slidably sleeving the slide rods 33 are opened. A limit disk 35 is fixed on the outer wall of the slide rod 33. A spring 36 is sleeved on the outer wall of the slide rod 33 and is located between the slider and the limit disk 35, as Figure 2 、 Figure 3 and Figure 7 shown. With the elastic force of the spring 36 located between the slider and the limit disk 35, the slider can be pushed in real time to the side away from the limit disk 35, that is, the two bearing rods 3 are separated from each other in real time to the side away from each other. This can avoid the water filtering cloth 31 sagging and slackening downward due to the two bearing rods 3 being close together under normal conditions, affecting the normal rolling and pressing of the rolling member.

[0037] It is by means of the elastic force of the spring 36 that the two bearing rods 3 are separated and adjusted in real time, so that the filter cloth 31 is in a relatively tensioned state without external force, as Figure 3 shown in the figure. The two short side side walls of the filter cloth 31 bend and extend upward, and the middle sinks downward. At the same time, the two ends of the side baffle cloth 32 are respectively extended to the two short side side walls of the filter cloth 31 and are arranged flush with each other to form the above-mentioned water filtering concave groove. Moreover, a steel wire rope 34 is arranged between the two bearing rods 3. The function of the steel wire rope 34 is to provide a hoisting force for the side baffle cloth 32 and improve the tensile strength of the side baffle cloth 32. As can be clearly shown in Figure 1 , the side wall of the filter cloth 31 does not contact the inner wall of the moving carriage 1. At the same time, there is a side baffle cloth 32 to block impurities in the sewage from entering the water filtering concave groove on the side. The sewage is poured into the storage space from the feed hopper 15 and will not be directly poured into the water filtering concave groove. All the silt mixed in the sewage is located in the storage space, and only the water body of the sewage can penetrate through the filter cloth 31 and soak into the water filtering concave groove. Here, the filter cloth 31 can be selected as canvas with fine mesh holes, which is strong and durable and does not affect the penetration of the water body.

[0038] A rolling member is also provided. The rolling member has a hollow sleeve 62 and rollers 6 rotatably arranged at both axial ends of the hollow sleeve 62. The rollers 6 can roll back and forth horizontally along the upper end surface of the filter cloth 31 in the water filtering concave groove. Specifically, support beams 12 are fixed to the outer tops of the two long side side walls of the moving carriage 1. A guide rail 13 is fixed to the edge of the upper end of the support beam 12 away from the moving carriage 1, and a toothed block 14 is provided on the edge close to the moving carriage 1. The rolling member further includes two sliding sleeves 51 slidably sleeved on the guide rail 13 and a cross beam 5 fixed between the two sliding sleeves 51. An installation hole is formed in the cross beam 5 above the toothed block 14, and a toothed disc 52 meshing with the toothed block 14 is rotatably arranged in the installation hole. A transmission rod 53 is fixed between the two toothed discs 52. The transmission rod 53 is rotationally embedded in the upper end surface of the cross beam 5. A first bevel gear is fixedly sleeved on the transmission rod 53. A motor is fixed to the upper end surface of the cross beam 5, and a second bevel gear meshing with the first bevel gear is fixed to the output end of the motor. As Figure 1 shown in the figure, the motor provides power for the second bevel gear. Through the meshing of the second bevel gear and the first bevel gear, the first bevel gear can drive the transmission rod 53 to rotate synchronously, and then drive the two toothed discs 52 to roll synchronously in the same direction. The two toothed discs 52 respectively roll effectively on the toothed blocks 14 on the two side support beams 12, and finally drive the sliding sleeves 51 to slide horizontally along the corresponding guide rails 13. The motor can be selected as a servo motor or a stepper motor, as long as it can provide power for the forward or reverse rotation of the toothed disc 52.

[0039] At the same time, one end of the roller 6 is a closed structure, and the other end is provided with a hollow socket end 61 rotatably sleeved on the end of the hollow sleeve 62, as Figure 6As shown, there are two drums 6. At both axial ends of the hollow sleeve 62, insertion ends are provided. The inner wall of the opening of the insertion end is provided with an annular flange. The two drums 6 are respectively rotationally inserted into the hollow sleeve 62 through their respective corresponding hollow socket ends 61. After the end of the hollow socket end 61 extends into the insertion end, an annular enlarged end is provided along the radial direction, ensuring that while the hollow socket end 61 can roll in the insertion end, it is not easy to separate from each other. In addition, a pull-out sleeve 63 is fixed to the outer wall of the hollow sleeve 62 in the radial direction. A suspension rod 64 is sleeved at the end of the pull-out sleeve 63. The suspension rod 64 is fixed to the bottom wall of the cross beam 5. After the bottom end of the suspension rod 64 extends into the pull-out sleeve 63, an annular enlarged end is provided along the radial direction. The inner wall of the upper opening of the pull-out sleeve 63 is also provided with a ring of annular flanges. In this way, the annular enlarged end abuts against the side wall of one end of the annular flange located in the pull-out sleeve 63, and the pull-out sleeve 63 and the suspension rod 64 do not separate without affecting the up and down sliding of the pull-out sleeve 63 along the outer wall of the suspension rod 64.

[0040] Here, due to the influence of the gravity of the drum 6, the pull-out sleeve 63 will slide down along the outer wall of the suspension rod 64 in real time, so that the drum 6 can fall on the upper surface of the water filter cloth 31. However, the falling height of the drum 6 just falls on the upper surface of the water filter cloth 31, and will not cause excessive downward pulling on the water filter cloth 31, thus avoiding excessive tearing and cracking. This is the case when there is no sewage in the moving carriage 1. Once the moving carriage 1 is filled with sewage mixed with silt, as the silt continuously accumulates, the rolling pressure height of the drum 6 will gradually rise, and the pull-out sleeve 63 will slide upward along the outer wall of the suspension rod 64. During this process, the self-gravity of the drum 6, the hollow sleeve 62 and the pull-out sleeve 63 is used to roll and compact the silt. It should be noted here that there is a water filter cloth 31 between the drum 6 and the sewage mixed with silt, and the silt is pressed and compacted into blocks, squeezing out the water body, and the water body penetrates through the water filter cloth 31 and enters the water filter concave groove.

[0041] In this embodiment, a negative pressure pump 4 is further included. Here, the negative pressure pump 4 is installed on the cross beam 5. The negative pressure pump 4 is provided with a drain pipe and an adsorption pipe connected to the outer wall of the hollow sleeve 62 in the radial direction. The radial side wall of the drum 6 is provided with liquid inlet mesh holes, and the hollow sleeve 62 and the drum 6 are in mutual communication. As Figure 1 and Figure 6 shown, during the rolling process of the drum 6, the sewage water body will enter the drum 6 and the hollow sleeve 62 through the liquid inlet mesh holes. A mobile generator is used to provide power for the negative pressure pump 4. The adsorption pipe is made of a corrugated hose, which can adaptively bend and stretch following the up and down adjustment of the height of the hollow sleeve 62. The adsorption pipe of the negative pressure pump 4 sucks out the water body filtered by the water filter cloth 31 from the hollow sleeve 62, and it can be sprayed out from the drain pipe to the side of the moving carriage 1 or externally guided through an external water pipe connected to the drain pipe.

[0042] The core point of the design of the present invention is its mobility. When sewage is poured into the mobile carriage 1, the water body of the sewage can be quickly separated from the silt, and a rolling part is equipped to roll and compact the silt, thereby increasing the collection volume of a single treatment in the mobile carriage 1, meeting the demand for silt filtration treatment in sewage from landscaping construction, and eliminating the need to temporarily dig a filter pool at the construction site, thereby saving construction time and construction costs.

[0043] In this embodiment, further, Figure 1 and Figure 2 As shown, a discharge port is provided on a short side wall of the mobile compartment 1, and a rear tailgate 2 is provided at the discharge port. L-shaped extension ends are provided on both sides of the discharge port, and the upper sides of the rear tailgate 2 are respectively hinged to the top of the side wall opposite to the two L-shaped extension ends. In this way, the rear tailgate 2 can be flipped around the hinge position as long as it is flipped horizontally. The purpose of this design is that when the mobile compartment 1 is full of sludge and needs to be discharged, the rear tailgate 2 can be opened by knocking on it. Figure 1 The state shown is turned clockwise and the discharge port can be opened, making it convenient for workers to shovel the silt with the help of tools.

[0044] An inverted L-shaped clamping notch 16 is provided at the bottom end of both sides of the discharge port, and a limit stopper 17 is inserted horizontally into the two inverted L-shaped clamping notches 16. When the rear tailgate 2 is vertically arranged, the limit stopper 17 abuts against the outer wall of the rear tailgate 2. By setting the limit stopper 17 against the outer wall of the rear tailgate 2, the rear tailgate 2 will not be opened easily, and the rear tailgate 2 is in a vertical state in real time and abuts against the outer wall of the L-shaped extension end, so as to avoid sludge leakage as much as possible.

[0045] The present invention also discloses a method for filtering and treating sewage sludge in a gardening project, comprising the following steps:

[0046] A1, the mobile carriage 1 can be movably arranged;

[0047] A2. The mobile carriage 1 has a storage space for storing sewage mixed with sludge. During the recycling process, the sludge is rolled and compacted in real time to reduce the sludge space share;

[0048] A3, the water filter cloth 31 separates and filters the sewage water and the sludge, and the negative pressure pump 4 provides negative pressure to suck the sewage water in real time.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
