Description

Technical Field

[0001] The utility model relates to the technical field of construction wastewater treatment, in particular to a device for reusing construction wastewater. Background Technique

[0002] Construction wastewater refers to the water body containing various pollutants generated during the construction process, mainly including rainwater, concrete mixing and washing wastewater, construction equipment washing wastewater, etc. The characteristics of construction wastewater are large water volume, complex composition, high pollutant concentration and large variation. It must be properly treated to meet the discharge standard or reuse standard before it can be discharged or reused.

[0003] For example, Chinese Patent CN202121277231.9 discloses a device for reusing wastewater in construction. The wastewater first undergoes stirring and fusion with a precipitant through a mixer, and then enters the first sedimentation tank for sedimentation through the cooperation of the first water pipe and the third water pipe on the top side. The clean water source at the top enters the bottom sedimentation tank through the overflow pipe, the second water pipe and the third water pipe for secondary sedimentation. The clean water at the top side overflows and is discharged through the water outlet pipe. The wastewater conversion efficiency is high, and at the same time, cyclic conversion and reuse can be achieved.

[0004] However, a large amount of construction waste residue is contained in the wastewater generated during construction. If these waste residues are not removed in advance and directly mixed with the precipitant for purification treatment, it will cause the precipitant to not react fully with the wastewater, and it is easy to cause blockage of the sedimentation tank, thereby affecting the wastewater treatment efficiency.

[0005] Based on this, the utility model designs a device for reusing construction wastewater to solve the above problems. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1

[0027] Please refer to Figure 1 - Figure 3 To illustrate Embodiment 1, a building wastewater reuse device shown in the figure includes a water inlet tank 1. A through groove 2 is opened on the left side of the water inlet tank 1. A guiding plate 3 is fixedly connected to the bottom of the through groove 2. A filter residue mechanism 4 is arranged on the left side of the guiding plate 3. A support frame 5 is fixedly connected to the bottom of the water inlet tank 1. The filter residue mechanism 4 is rotatably connected to the support frame 5. A slag discharge box 6, a slag discharge plate 7 and a drainage plate 8 are arranged on the base of the filter residue mechanism 4 from left to right in sequence. A vibration assembly 9 is connected to the top of the drainage plate 8;

[0028] The filter residue mechanism 4 includes a rotating shaft 401, a first filter cylinder 402 and a second filter cylinder 403. The first filter cylinder 402 and the second filter cylinder 403 are fixedly connected to the rotating shaft 401 from left to right in sequence. A slag discharge plate 7 is correspondingly arranged at the bottom of the first filter cylinder 402. A drainage plate 8 is correspondingly arranged at the bottom of the second filter cylinder 403.

[0029] In this embodiment, the construction wastewater is conveyed into the water inlet tank 1 and flows into the guiding plate 3 through the through groove 2. The guiding rod plate 3 is inclined and extends into the slag filtering mechanism 4, thereby guiding the wastewater to flow towards the slag filtering mechanism 4. Due to the rotational movement of the slag filtering mechanism 4, the construction waste residues are effectively separated and fall into the slag discharge box 6 and the slag discharge plate 7 according to the specifications of the construction waste residues. At the same time, the wastewater passes through the filtration and flows into the drainage plate 8. The drainage plate 8 maintains stable water discharge under the action of the vibration assembly 9 and is guided and conveyed through the drainage plate 8 to the subsequent wastewater treatment device for further treatment operations.

[0030] It should be noted that side plates are provided at the edges of the guiding plate 3, the slag discharge plate 7, and the drainage plate 8, and the guiding plate 3, the slag discharge plate 7, and the drainage plate 8 are all arranged in a slope shape, which is convenient for effectively separating the construction waste residues and the wastewater.

[0031] Embodiment 2

[0032] Please refer to Figure 4 and Figure 5 Referring to Embodiment 2, this embodiment further describes Embodiment 1. In the figure, bearing seats 404 are connected to both ends of the rotating shaft 401. The bearing seats 404 are fixedly connected to the support frame 5, and a driven wheel 405 is fixedly connected to the right end of the rotating shaft 401. A belt 406 is sleeved on the driven wheel 405, and a servo motor 407 is connected to the bottom of the belt 406.

[0033] Furthermore, a number of long rods are evenly arranged at equal intervals in the first filter cylinder 402 and the second filter cylinder 403, and the distance between two adjacent long rods in the first filter cylinder 402 is greater than the distance between two adjacent long rods in the second filter cylinder 403.

[0034] Furthermore, the right end of the first filter cylinder 402 is connected to the second filter cylinder 403, and the rotating shaft 401, the first filter cylinder 402, and the second filter cylinder 403 are arranged in a left-low and right-high inclined manner.

[0035] In this embodiment, when the servo motor 407 is powered on to output power, it drives the rotating shaft 401 and the first filter cylinder 402 and the second filter cylinder 403 to rotate synchronously. The construction wastewater first passes through the second filter cylinder 403 to separate the water body from the construction waste residues. The separated water body falls into the drainage plate 8 under the action of gravity, and the separated construction waste residues continue to be conveyed to the left and enter the second filter cylinder 403. The construction waste residues of corresponding specifications fall into the slag discharge plate 7 through the gaps between the long rods, and the remaining construction waste residues continue to be conveyed to the left out of the second filter cylinder 403 and fall into the slag discharge box 6. Moreover, the distances between two adjacent long rods in the first filter cylinder 402 and the second filter cylinder 403 are different, which can effectively separate waste residues of different sizes.

[0036] Embodiment 3

[0037] Please refer to Figure 1 andFigure 6 Referring to Embodiment 3, this embodiment further describes Embodiment 2. In the illustration, a movable plate 801 is movably connected to the front side of the drainage plate 8 through a hinge, and the front side of the movable plate 801 is funnel-shaped.

[0038] Furthermore, the vibration assembly 9 includes a connecting plate 901, a vibration motor 902, and a telescopic rod 903. The connecting plate 901 is fixedly connected to the movable plate 801, the vibration motor 902 is fixedly installed at the center position of the top of the connecting plate 901, and the telescopic rods 903 are symmetrically arranged on the left and right sides of the vibration motor 902.

[0039] Furthermore, the rear end of the telescopic rod 903 is rotatably connected to the front side of the support frame 5, and the front end of the telescopic rod 903 is rotatably connected to the connecting plate 901.

[0040] In this embodiment, when the vibration motor 902 is powered on, it generates periodic vibrations, driving the entire area of the movable plate 801 to generate micro-vibrations, making the flow of wastewater smoother, reducing the residence time of wastewater during drainage, and the funnel-shaped design on the front side of the movable plate 801 can concentrate the flow direction of the wastewater generated by the vibration. In addition, during the vibration process, the telescopic rod 903, as a flexible connection between the movable plate 801 and the support frame 5, can control the stability of the movement of the movable plate 801.

[0041] It should be noted that the vibration frequency and amplitude of the vibration assembly 9 can be adjusted according to actual usage conditions to adapt to different treatment requirements. At the same time, the telescopic rod 903 of the vibration assembly 9 can perform telescopic movement during the vibration process, further improving the vibration effect and preventing fine particles inside from accumulating and precipitating on the front side of the movable plate 801 during the long-term output of wastewater, which may affect the water outlet effect.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
