Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and in particular relates to wastewater collecting and filtering equipment, a wastewater circulating treatment system and a method. Background Art

[0002] In engineering fields such as construction, a large amount of wastewater containing solid debris and sediment will be generated during the construction process. If this wastewater is discharged directly without treatment, it will cause serious pollution to the environment and also cause a waste of water resources.

[0003] In the prior art, a Chinese patent with the announcement number CN218204853U discloses a wastewater recycling collection and treatment device for environmentally friendly building construction. By setting up a water collection channel at the construction site and laying water collection coils, water is concentrated in the water collection tank and undergoes preliminary filtration treatment under the osmosis effect of the seepage tank.

[0004] A Chinese patent with announcement number CN215439985U discloses an environmentally friendly wastewater collection and treatment device, including a treatment bin, wherein the left inner wall and the right inner wall of the treatment bin are fixedly connected with a slide rail, and sliders are slidably connected in the two slide rails, and the opposite sides of the two sliders are fixedly connected with connecting plates, the top surfaces of the two connecting plates are fixedly connected with coarse filter plates, and the bottom surfaces of the two connecting plates are fixedly connected with fine filter plates. Under the action of the coarse filter plates and the fine filter plates, the solids remaining in the wastewater can be filtered, and the wastewater can be separated into solid and liquid. The coarse filter plates and the fine filter plates are connected by the connecting plates, and the sliding connection between the slide rails and the sliders can facilitate the staff to extract the two filter plates and then clean the two filter plates.

[0005] Although the above two patents can enable centralized recycling of wastewater and can perform preliminary solid-liquid separation of wastewater to a certain extent, there are certain defects in actual use. The solid debris after preliminary filtration needs to be manually cleaned regularly. The cleaning process is not only manpower-consuming, but also has the risk of debris accumulation and clogging the screen gaps due to untimely cleaning, thereby greatly reducing the filtration efficiency and affecting the continuity of the entire wastewater collection and treatment process.

[0006] Therefore, how to automatically clean the filtered solid debris is a technical problem that needs to be solved urgently in this field. Summary of the Invention

[0007] The present invention aims to solve the problem in the prior art that solid debris after filtration needs to be cleaned manually on a regular basis, which is time-consuming and labor-intensive, increases the risk of clogging, and reduces filtration efficiency.

[0046] In the prior art, in order to prevent the filter plates of wastewater filtration from being clogged by solid debris, it is necessary to manually remove the debris after filtration, which is time-consuming and labor-intensive and reduces the filtration efficiency.

[0047] In order to solve the above technical problems, the present invention provides a wastewater collection and filtration device, such as Figure 1 As shown, the wastewater collection and filtration equipment includes a collection tank 1, a filtration mechanism and a filter waste recovery tank 2:

[0048] The collection tank 1 is configured to collect wastewater;

[0049] The filtering mechanism includes a rotating disk 3 and at least one filter plate 301. The rotating disk 3 is rotatably connected to the collection tank 1 and is at least partially located on one side of the interior of the collection tank 1. The filter plate 301 is mounted on the circumferential outer wall of the rotating disk 3.

[0050] The filtered waste recovery tank 2 is located at the other side of the collection tank 1 and is configured to recover the waste intercepted by the filter plate 301 .

[0051] By arranging a filtering mechanism and a filter waste recovery tank 2 in the collection pool 1, the present invention eliminates the need for regular manual cleaning of debris on the filter plate 301, effectively avoiding accumulation and clogging of debris and greatly improving the filtering efficiency.

[0052] In a feasible embodiment of the present invention, the collecting tank 1 is provided with a collecting pipe 101 and a drain pipe 105, and the collecting pipe 101 is close to the top of the collecting tank 1 relative to the discharge pipe. For example, the collecting pipe 101 is provided at the end of the collecting tank 1, and the drain pipe 105 is provided on the side wall of the collecting tank 1.

[0053] In a feasible embodiment of the present invention, the filtering mechanism further includes a mounting frame 2 , which is fixedly or detachably mounted on the top of the collection tank 1 , and the rotating disk 3 is rotatably connected to the mounting frame 2 .

[0054] In a feasible embodiment of the present invention, the filtering mechanism further includes a driving motor 201, which is configured to drive the rotating disk 3 to rotate.

[0055] In a feasible embodiment of the present invention, a plurality of filter plates 301 are arranged at equal angles on the circumferential outer wall of the rotating disk 3 .

[0056] In a feasible embodiment of the present invention, the rotating disk 3 is in an I-shape. When the filtering mechanism includes multiple filter plates 301, the adjacent filter plates 301 and the inner walls on both sides of the rotating disk 3 and the circumferential outer wall surround an outwardly open collection trough 304, collecting wastewater in the collection trough 304, thereby improving the filtering effect of the wastewater.

[0057] Preferably, the external opening size of the above-mentioned collection tank 304 is larger than the corresponding bottom size, which facilitates the wastewater to enter the bottom of the collection tank 304 and improves the filtering effect.

[0058] Preferably, the filter plate 301 extends out of the two side walls of the rotating disk 3 to facilitate the waste on the filter plate 301 to fall into the filtered waste recovery tank 2.

[0059] In a feasible embodiment of the present invention, the side wall of the filter waste recovery tank 2 close to the filter mechanism is designed to be inclined, so that the top size of the filter waste recovery tank 2 is larger than the bottom size, which facilitates the sliding of waste.

[0060] Preferably, a guide groove 3 is provided at the bottom of the filtered waste recovery tank 2 , and a discharge port 104 is opened at the bottom of the guide groove 3 .

[0061] In one possible embodiment of the present invention, Figure 1 and Figure 2 As shown, a filtering mechanism is provided inside the collection pool 1 of the wastewater collection and filtration equipment, and the filtering mechanism includes a mounting frame 2 fixedly mounted on the top of the collection pool 1, and a rotating disk 3 is rotatably mounted on the inner wall of the mounting frame 2, and a filter plate 301 is provided on the inner wall of the rotating disk 3, and a driving motor 201 is fixedly mounted on the outer wall of the mounting frame 2, a filtered waste recovery tank 2 is opened at the end of the collection pool 1, a collection pipe 101 is provided at the end of the collection pool 1, and a drain pipe 105 is provided on the side wall of the collection pool 1, two groups of mounting frames 2 are symmetrically arranged on the top of the collection pool 1, and the rotating disk 3 is located between the two groups of mounting frames 2, the output end of the driving motor 201 is connected to the rotating disk 3, the filter plates 301 are arranged at equal angles on the inner wall of the rotating disk 3, and a collection tank 304 is formed between the two groups of filter plates 301, and the inner walls on both sides of the collection tank 304 are inclined. 01 length is the same as the distance between the bottom of the collecting trough 304 and the outer wall of the rotating disk 3, and the width of the filter plate 301 is the same as the distance between the inner walls on both sides of the rotating disk 3, the inner wall of the rotating disk 3 is provided with mounting grooves 302 at equal angles, and the inner wall of the mounting groove 302 is fitted with the outer wall of the filter plate 301, the outer wall of the rotating disk 3 is symmetrically provided with fixing bolts 303, and the filter plate 301 is fixedly installed on the inner wall of the mounting groove 302 by fixing bolts 303, the filter waste recovery trough 2 is located at the end of the collecting pool 1 away from the collection pipe 101, and the filter waste recovery trough 2 is close to the inner wall of the filter plate 301 and is inclined, and the top opening of the filter waste recovery trough 2 is larger than the bottom opening, the bottom of the filter waste recovery trough 2 is provided with a guide groove 3, and the bottom of the guide groove 3103 is provided with an excretion port 104, and the cross-section of the guide groove 3 is V-shaped.

[0062] The wastewater collection and filtration method of the above-mentioned wastewater collection and filtration equipment includes:

[0063] The wastewater generated during construction flows into the collection tank 1 through the collection pipe 101. At this time, the driving motor 201 is started, driving the rotating disk 3 to rotate on the inner wall of the mounting frame 2. The filter plates 301 arranged at equal angles on the rotating disk 3 rotate accordingly. When the filter plates 301 rotate to the contact position with the wastewater, the solid debris in the wastewater is intercepted by the filter plates 301, and the filtered wastewater continues to remain in the collection tank 1. As the rotating disk 3 continues to rotate, the debris intercepted by the filter plates 301 is brought to the top of the filter waste recovery tank 2. Since the inner walls on both sides of the collection tank 304 are inclined and the length of the filter plate 301 is adapted to the distance between the bottom of the collection tank 304 and the outer wall of the rotating disk 3, the debris automatically slides into the filter waste recovery tank 2 under the action of gravity, and is then discharged from the collection tank 1 through the guide groove 3 at the bottom of the filter waste recovery tank 2 and the discharge port 104, thereby realizing automatic filtration without the need for manual cleaning.

[0064] In order to facilitate the waste to fall into the filter waste recovery trough 2, in an optional embodiment of the present invention, the side wall of the collection trough 304 is provided with a slide rail, and the side panel of the filter waste recovery trough 2 facing the filter mechanism is configured to be able to slide along the slide rail, and the top of the side panel is inclined close to the filter mechanism. Through the sliding of the side panel, the top of the side panel is located below the filter plate 301, and the bottom of the side panel is located outside the filter plate 301, which does not damage the filter plate 301 while facilitating the waste falling from the filter plate 301 to slide along the inclined surface of the side panel.

[0065] In order to facilitate the waste to fall into the filter waste recovery tank 2, in an optional embodiment of the present invention, slide rails are provided on the inner walls on both sides of the rotating disk 3, and the filter plate 301 is configured to be able to slide along the slide rails, so that the filter plate 301 reaches above the filter waste recovery tank 2.

[0066] In order to facilitate the waste to fall into the filtered waste recovery tank 2, in an optional embodiment of the present invention, the filtering mechanism also includes a vibration component, which is configured to vibrate the filter plate 301 so that the waste on the filter plate 301 is shaken off, for example, a microvibrator is installed on the filter plate 301.

[0067] In order to facilitate the waste to fall into the filter waste recovery tank 2, in one embodiment of the present invention, the filtering mechanism also includes a deflection member, which is configured to adjust the inclination angle of the filter plate 301 relative to the top surface of the filter waste recovery tank 2. The larger the inclination angle, the more conducive it is for the waste to fall from the filter plate 301.

[0068] Various embodiments for facilitating the falling of waste into the filtered waste recovery tank 2 are shown above, but the present invention is not limited thereto and may be a combination of the above embodiments. For example, the filtering mechanism further includes a micro eccentric rotor vibration motor, which drives the filter plate 301 to deflect and vibrate at the same time; for another example, slide rails are provided on the inner walls on both sides of the rotating disk 3, and sliders slide on the slide rails. The micro eccentric rotor vibration motor is installed on the slider, and the rotating shaft of the micro eccentric rotor vibration motor is connected to the filter plate 301; for another example, an eccentric block is provided on the circumferential outer wall of the rotating disk 3, slide rails are provided on the inner walls on both sides of the rotating disk 3, and a vibration plate is provided on the slider. The filter plate 301 is moved to the top of the filtered waste recovery tank 2 by the slide rail slider, the filter plate 301 is rotated by the eccentric block, and the filter plate 301 is vibrated by the vibration plate.

[0069] The present invention sets a filtering mechanism in the collection tank 1, drives the rotating disk 3 to rotate by the driving motor 201, and makes the filter plate 301 circulate and filter the solid debris in the wastewater, without the need for manual cleaning on a regular basis. When the debris intercepted by the filter plate 301 rotates with the rotating disk 3 to the position of the filter waste recovery tank 2, the inclined inner wall of the collection tank 304 and the structure of the filter plate 301 itself are utilized to make the debris automatically slide to the filter waste recovery tank 2 for discharge, effectively avoiding the accumulation of debris and blockage, greatly improving the filtration efficiency, and ensuring the continuity of the wastewater collection and treatment process.

[0070] Wastewater treated only by filtration often fails to meet discharge standards. Therefore, in one embodiment of the present invention, the wastewater filtered by the wastewater collection and filtration equipment enters the sedimentation tank 4 for sedimentation, and the upper layer of clear water after sedimentation is discharged.

[0071] In view of this, the present invention provides a wastewater recycling collection and treatment system, such as Figure 3 As shown, the wastewater circulation collection and treatment system includes the wastewater collection and filtration equipment of the above embodiments and a sedimentation tank 4. The sedimentation tank 4 is connected to the collection tank 1 and is configured to precipitate the wastewater filtered by the filtration mechanism.

[0072] When the wastewater after preliminary filtration enters the sedimentation tank 4, if there is a lack of buffer diversion, the water flow will directly act on the sediment formed at the bottom of the sedimentation tank 4 with a large impact force, causing the sediment at the bottom to be stirred and suspended, seriously interfering with the normal progress of the sedimentation process, greatly reducing the sedimentation treatment effect, and making it difficult to ensure the water quality requirements of the subsequent treatment links, which ultimately makes it difficult for the treated wastewater to meet the ideal discharge standards and recycling conditions.

[0073] Therefore, in a preferred embodiment of the present invention, Figure 4-Figure 6 As shown, the sedimentation tank 4 is also provided with a buffer mechanism, a clean water outlet mechanism and a sewage discharge mechanism;

[0074] One end of the buffer mechanism is connected to the collection tank 1, and the other end of the buffer mechanism is connected to the sedimentation tank 4. The buffer mechanism is configured to buffer the filtered wastewater before it flows into the sedimentation tank 4.

[0075] The clean water outlet mechanism is connected to the sedimentation tank 4 and is configured to outlet the upper layer of clean water after the wastewater is precipitated;

[0076] The sewage discharge mechanism is configured to discharge waste after the wastewater is precipitated in the sedimentation tank 4 .

[0077] The wastewater recycling collection and treatment system of the present invention is an intelligent and environmentally friendly construction wastewater recycling collection and treatment equipment. By arranging a filtering mechanism in the collection tank 1, there is no need for manual cleaning on a regular basis, which effectively avoids clogging due to accumulation of debris and greatly improves the filtration efficiency. The buffer mechanism effectively alleviates the impact of the water flow on the sediment at the bottom of the sedimentation tank 4, ensuring the stable sedimentation process and significantly improving the sedimentation treatment effect.

[0078] In one possible embodiment of the present invention, Figure 5 and Figure 6 As shown, the buffer mechanism includes a buffer tube 5 and a buffer block 501:

[0079] The buffer pipe 5 is connected to the collection tank 1 and is installed inside the sedimentation tank 4. The buffer pipe 5 is further provided with a through groove 502, and the through groove 502 connects the buffer pipe 5 and the sedimentation tank 4;

[0080] The buffer block 501 is disposed in the buffer tube 5 .

[0081] Preferably, the buffer block 501 is in one or more of a cone shape, an arc shape and a spiral shape that protrudes into the buffer tube 5 .

[0082] In one possible embodiment of the present invention, Figure 5 and Figure 6 As shown, the clean water outlet mechanism includes a water baffle 6 , which forms a water trough with the inner wall of the sedimentation tank 4 , and the top height of the water baffle 6 close to the buffer tube 5 is lower than the top height of the buffer tube 5 .

[0083] Preferably, the water retaining plate 6 has an L-shaped cross section.

[0084] In a preferred embodiment of the present invention, a buffer mechanism for alleviating the impact of water flow on sediment is provided inside the sedimentation tank 4, and the buffer mechanism includes a buffer tube 5 fixedly installed inside the sedimentation tank 4, and a buffer block 501 is provided at the bottom of the buffer tube 5, and a through groove 502 is provided on the outer wall of the buffer tube 5. A clean water outlet mechanism - a water baffle 6 is fixedly installed on the inner wall of the sedimentation tank 4, a connecting pipe 701 is provided on the outer wall of the sedimentation tank 4, a sewage outlet 401 is provided at the bottom of the sedimentation tank 4, and a sewage suction pipe 402 is provided at the end of the sewage outlet 401, the drain pipe 105 is designed to be inclined, and one end of the drain pipe 105 is located inside the buffer tube 5, and the other end of the drain pipe 105 is connected to the inside of the collecting tank 304, and the drain pipe 105 is located inside the buffer tube 5 at one end. The mouth is facing upward, the top of the buffer tube 5 is aligned with the top of the sedimentation tank 4, and the length of the buffer tube 5 is less than the length of the sedimentation tank 4. The buffer block 501 is conical in design, and the outer diameter of the bottom of the buffer block 501 is equal to the inner diameter of the buffer tube 5. The through grooves 502 are distributed at equal angles on the outer wall of the bottom of the buffer tube 5, and one end of the through grooves 502 is connected to the interior of the sedimentation tank 4, and the other end of the through grooves 502 is connected to the interior of the buffer tube 5. The water baffle 6 is located at the top of the sedimentation tank 4, and the horizontal plane of the top of the water baffle 6 is lower than the horizontal plane of the top of the buffer tube 5. The cross-section of the water baffle 6 is L-shaped, and the outer wall of the water baffle 6 and the inner wall of the sedimentation tank 4 form a water trough, and the bottom of the water baffle 6 is inclined. The connecting pipe 701 is located between the water baffle 6 and the top of the sedimentation tank 4.

[0085] The wastewater recycling collection and treatment method of the wastewater recycling collection and treatment system includes:

[0086] The wastewater that has been preliminarily filtered by the collection tank 1 flows into the buffer mechanism of the sedimentation tank 4 through the drain pipe 105 with an inclined design on the side wall of the collection tank 1. One end of the drain pipe 105 is located inside the buffer pipe 5 and the opening is facing upward. The wastewater first enters the buffer pipe 5 and then flows out through the through grooves 502 distributed at equal angles at the bottom of the buffer pipe 5. In this process, the conical buffer block 501 plays a diversion role, dispersing the concentrated water flow and slowing down the flow rate, effectively reducing the impact of the water flow on the sediment at the bottom of the sedimentation tank 4, so that the sediment can be stably deposited at the bottom of the tank. As the wastewater continues to flow in, the water level of the upper clean water that has been precipitated gradually rises. When the water level exceeds the top of the water baffle 6, the clean water passes over the water baffle 6 and flows into the water trough formed by the water baffle 6 and the inner wall of the sedimentation tank 4. Because the bottom of the water baffle 6 is designed to be inclined, the clean water flows smoothly into the water storage tank 7 through the connecting pipe 701.

[0087] In addition, the sewage outlet 401 at the bottom of the sedimentation tank 4 is connected to the sewage suction pipe 402, which can regularly suck out the settled sludge and ensure the normal operation of the sedimentation tank 4.

[0088] The present invention provides a buffer mechanism in the sedimentation tank 4. The drain pipe 105 transports the wastewater filtered by the collection tank 1 to the buffer pipe 5. The wastewater is dispersed and flows out through the through groove 502 at the bottom of the buffer pipe 5. Combined with the diversion effect of the conical buffer block 501, the impact of the water flow on the sediment at the bottom of the sedimentation tank 4 is effectively alleviated, preventing the sediment from being stirred and suspended, ensuring the stability of the sedimentation process, and significantly improving the sedimentation treatment effect.

[0089] The water baffle 6 in the clean water outlet mechanism of the present invention forms a water trough with the inner wall of the sedimentation tank 4, and the bottom of the water baffle 6 is designed to be inclined, so that the upper clean water that has undergone sedimentation treatment can flow smoothly into the water trough and then enter the water storage tank 7 through the connecting pipe 701, avoiding the secondary impact of water flow fluctuations on the sedimentation effect and further ensuring the effectiveness of the sedimentation treatment.

[0090] In order to facilitate the storage, use and / or further treatment of the upper layer of clear water after sedimentation in the sedimentation tank 4, in one embodiment of the present invention, as Figure 3 and Figure 7 As shown, the wastewater circulation collection and treatment system further includes a water storage tank 7 , which is connected to the sedimentation tank 4 and is configured to store the upper layer of clear water after the wastewater is precipitated in the sedimentation tank 4 .

[0091] In one possible embodiment of the present invention, Figure 7-Figure 9 As shown, the water storage tank 7 further includes one or more of the following components:

[0092] The packing layer 8 is configured to purify the upper layer of clear water;

[0093] A disinfection lamp 703 is provided inside the water storage tank 7 and is configured to disinfect the upper layer of clean water;

[0094] The water quality monitor 9 is configured to monitor the quality of the purified water pre-discharged from the water storage tank 7;

[0095] a controller configured to at least receive data from the water quality detector;

[0096] The top cover 702 is configured to cover the opening of the water tank 7. Preferably, one or more handles are provided on the top cover 702 to facilitate opening and closing of the top cover 702.

[0097] In a preferred embodiment of the present invention, the water tank 7 is connected to the sedimentation tank 4 through a connecting pipe 701, and a top cover 702 is provided on the top of the water tank 7, and a disinfection lamp 703 is provided at the bottom of the top cover 702, and the disinfection lamp 703 is arranged at an equal angle at the bottom of the top cover 702. A packing layer 8 is provided in the middle position inside the water tank 7 for further purifying and recycling wastewater. A water quality monitor 9 is provided at the bottom of the water tank 7, and the water quality detector is electrically connected to the controller. A water outlet 704 is provided on the outer wall of the bottom of the water tank 7, and the water outlet 704 is connected to the construction equipment.

[0098] The wastewater recycling collection and treatment method of the wastewater recycling collection and treatment system includes:

[0099] In the water storage tank 7, the incoming clean water first passes through the packing layer 8, which further adsorbs and filters the impurities and pollutants remaining in the wastewater to purify the water quality. At the same time, the disinfection lamp 703 set at an equal angle at the bottom of the top cover 702 continues to work, releasing ultraviolet rays and other light to disinfect the water body and kill bacteria and microorganisms in the water.

When the water quality reaches the set standard, the purified clean water can be transported to the construction equipment through the outlet 704 on the bottom outer wall to realize the recycling of wastewater. If the water quality does not meet the standard, the water in the water storage tank 7 can be subjected to secondary treatment or returned to the sedimentation tank 4 for further sedimentation treatment according to the instructions of the controller.

The water quality monitor 9 at the bottom monitors the water quality in real time and transmits the data to the control platform to ensure that the treated wastewater reaches the ideal water quality standard and meets the water demand of the construction equipment, thereby realizing the efficient recycling of construction wastewater, reducing environmental pollution and improving the utilization rate of water resources.
