DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0023] In the embodiments of the present application, the description such as "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features.

[0024] In the embodiments, as shown in Figure 1 and Figure 2 , a concrete cleaning wastewater recycling device 1 provided by the embodiments includes a wastewater storage and delivery assembly 10, a clean water storage and delivery assembly 11, a homogenizing agent storage and delivery assembly 12, a dosage control assembly 20, a solid content detection assembly 30 and a mixed storage and delivery assembly 40.

[0025] The wastewater storage and delivery assembly 10, the clean water storage and delivery assembly 11 and the homogenizing agent storage and delivery assembly 12 are respectively connected to the mixed storage and delivery assembly 40. The solid content detection assembly 30 is arranged in the wastewater storage and delivery assembly 10, the dosage control assembly 20 is electrically connected to the solid content detection assembly 30, and the dosage control assembly 20 is used to control the dosage of the materials delivered by the wastewater storage and delivery assembly 10, the clean water storage and delivery assembly 11 and the homogenizing agent storage and delivery assembly 12 to the mixed storage and delivery assembly 40 according to the detection result of the solid content detection assembly 30.

[0026] Specifically, the wastewater storage and delivery assembly 10 includes a structure or container for storing concrete cleaning wastewater, such as a wastewater tank 105, and a delivery device for delivering the concrete cleaning wastewater, such as a wastewater delivery pump 101 and a wastewater delivery pipeline 104, the clean water storage and delivery assembly 11 includes a structure or container for storing clean water, such as a clean water tank 111, and a delivery device for delivering the clean water, such as a clean water delivery pump 102 and a clean water delivery pipeline 110, and the homogenizing agent storage and delivery assembly 12 includes a structure or container for storing a homogenizing agent solution, such as a homogenizing agent tank 121, and a delivery device for delivering the homogenizing agent, such as a homogenizing agent delivery pump 103 and a homogenizing agent delivery pipeline 120. It should be noted that the wastewater tank 105, the clean water tank 111 and the homogenizing agent tank 121 are not limited to tanks or containers, but any container that can be used to store liquid. The dosage control assembly 20 controls the flow rate of the wastewater, the clean water and the homogenizing agent to achieve the desired volume of the wastewater, the clean water and the homogenizing agent. It should be noted that the homogenizing agent composition includes propylene glycol, triisopropanolamine, ethylene glycol, sodium polyacrylate or water. The dosage control assembly 20 can be a flow controller composed of a flow meter, a signal controller, etc. In the present embodiment, the flow meter can be, for example, an electromagnetic flow meter. The solid content detection assembly 30 is used to detect the proportion of solid content in the liquid, which can be, for example, a density detector. In the present embodiment, the density detector can be, for example, a tuning fork density meter. The mixed solution storage and delivery assembly 40 is provided with a mixed solution tank 401 for storing the mixed solution of the wastewater, the clean water and the homogenizing agent.

[0027] The solid content detection assembly 30 detects the density of the wastewater to be treated stored in the wastewater tank 105, and according to the current wastewater density value, sets the density of the finished product that can achieve wastewater recovery and the water consumption per unit of concrete, calculates the required proportioning volume of the wastewater, the clean water and the homogenizing agent, and the dosage control assembly 20 controls the required proportioning volume of the wastewater, the clean water and the homogenizing agent to flow into the mixed solution tank 401. The mixed solution tank 401 stores the mixed solution of the wastewater, the clean water and the homogenizing agent mixed according to the required proportioning, which can be used for long-term storage or directly delivered to subsequent process steps.

[0028] The proportion of the required clean water and the added homogenizing agent is adjusted according to the density of the wastewater to be treated, so that the wastewater, the clean water and the homogenizing agent can be mixed in the most suitable proportion, maximizing the effective use of resources. The addition of the homogenizing agent with the appropriate proportion in the wastewater treatment effectively improves the performance of the concrete after production, so that the wastewater can remain undivided within 2-5 hours. And in the process of concrete mixing, it can significantly improve the strength of the concrete, so that the concrete structure is more compact, ensuring that the concrete can better withstand various loads in the building. Secondly, it can actively improve the workability of the concrete, making the concrete easier to pour and vibrate during construction, avoiding the separation of aggregates and cement paste in the concrete and the appearance of bleeding. At the same time, it reduces the viscosity of the concrete and thus reduces the water consumption per unit of concrete.

[0029] In the embodiment of the utility model, refer to Figure 2 As shown in the figure, the dosing amount control assembly 20 further includes a first flow detection device 201, a second flow detection device 202 and a third flow detection device 203, the wastewater storage and delivery assembly 10 includes a wastewater delivery pipeline 104, the clean water storage and delivery assembly 11 includes a clean water delivery pipeline 110, and the homogenizing agent storage and delivery assembly 12 includes a homogenizing agent delivery pipeline 120. The first flow detection device 201 is arranged on the wastewater delivery pipeline 104, the second flow detection device 202 is arranged on the clean water delivery pipeline 110, and the third flow detection device 203 is arranged on the homogenizing agent delivery pipeline 120.

[0030] The first flow detection device 201 is used to detect the flow rate when the wastewater is delivered, the second flow detection device 202 is used to detect the flow rate when the clean water is delivered, and the third flow detection device 203 is used to detect the flow rate when the homogenizing agent is delivered, and the flow rate data is transmitted to the dosing amount control assembly 20 to dynamically adjust the flow rate according to the difference between the set value and the actual measured value. It should be noted that the set value is the calculated volume ratio of the wastewater, the clean water and the homogenizing agent according to the current wastewater density value and the set density of the finished product and the water consumption per unit of concrete. Exemplarily, the flow detection device can be an electromagnetic flowmeter. The first flow detection device 201, the second flow detection device 202 and the third flow detection device 203 can ensure that the wastewater, the clean water and the homogenizing agent are mixed according to the preset ratio, avoid the deviation of the mixing ratio caused by inaccurate flow rate, and ensure the stable performance of the mixed liquid. Exemplarily, the flow detection device can be an electromagnetic flowmeter, an ultrasonic flowmeter and a turbine flowmeter, etc., and the electromagnetic flowmeter is selected in the embodiment.

[0031] The dosing amount control assembly 20 further includes a first valve 204, which is arranged on the homogenizing agent delivery pipeline 120 and located at the front end of the homogenizing agent delivery pump 103. Exemplarily, the first valve 204 can be an electrically controlled or manually controlled valve formed by a butterfly valve, a gate valve, etc. The first valve 204 is used to control the delivery of the homogenizing agent in the homogenizing agent tank 121, and the opening size of the first valve 204 can be changed according to the required ratio of the homogenizing agent to realize the flow rate change of the homogenizing agent delivery.

[0032] Refer to Figure 2 , Figure 3 and Figure 4As shown in the embodiment of the utility model, the concrete cleaning wastewater recycling device 1 further includes a plurality of one-way check valves 205, which are respectively arranged on the wastewater output pipeline 104, the clean water output pipeline 110 and the homogenizing agent output pipeline 120 and close to the mixed storage and delivery assembly 40. Specifically, the one-way check valves 205 are arranged on the wastewater output pipeline 104 close to the common flow pipeline 50. The one-way check valves 205 are arranged on the clean water output pipeline 110 close to the common flow pipeline 50. The one-way check valves 205 are arranged on the homogenizing agent output pipeline 120 close to the common flow pipeline 50.

[0033] The one-way check valves 205 can limit the wastewater, clean water and homogenizing agent to flow only in the direction of flowing into the common flow pipeline 50, so as to avoid the mixed liquid in the common flow pipeline 50 from flowing back into the wastewater storage and delivery assembly 10, the clean water storage and delivery assembly 11 or the homogenizing agent storage and delivery assembly 12 to contaminate the wastewater, clean water or homogenizing agent. In addition, the occurrence of pipeline blockage and other conditions caused by the backflow of the mixed liquid is reduced.

[0034] In the embodiment of the utility model, referring to Figure 2 As shown, the concrete cleaning wastewater recycling device 1 further includes a mixed solid content detection assembly 31, which is electrically connected with the dosing amount control assembly 20 and arranged on the mixed storage and delivery assembly 40.

[0035] The mixed solid content detection assembly 31 is used to measure the density of the mixed liquid composed of the wastewater, clean water and homogenizing agent in the mixed storage and delivery assembly 40. If the density of the mixed liquid is detected to be greater than the set product density, the dosing amount control assembly 20 is controlled to continue flowing the clean water into the mixed storage and delivery assembly 40 until the density of the mixed liquid is equal to the product density. The mixed solid content detection assembly 31 monitors the density of the mixed liquid in real time, which helps the dosing amount control assembly 20 to further optimize the ratio of the wastewater, clean water and homogenizing agent. In addition to the initial control according to the preset ratio, when it is found that the density of the mixed liquid does not meet the requirements, the inflow amount of each component can be more reasonably changed in the subsequent adjustment process, so as to realize more fine adjustment of the ratio. Exemplarily, the mixed solid content detection assembly 31 may, for example, be a tuning fork densitometer.

[0036] In the embodiment of the utility model, referring to Figure 2 As shown, the concrete cleaning wastewater recycling device 1 further includes a common flow pipeline 50, and the wastewater storage and delivery assembly 10, the clean water storage and delivery assembly 11 and the homogenizing agent storage and delivery assembly 12 are respectively connected with the liquid inlet end of the common flow pipeline 50, and the mixed storage and delivery assembly 40 is connected with the liquid outlet end of the common flow pipeline 50.

[0037] The dosing amount control assembly 20 controls the inflow of the clean water, the wastewater and the homogenizing agent, wherein the dosing amount control assembly 20 controls the two-time dosing of the clean water, and the amount of the two-time dosing of the clean water is equal to the proportioning volume of the clean water delivered to the mixed storage and delivery assembly 40. The dosing amount control assembly 20 controls the inflow of part of the clean water, and the part of the clean water flows into the mixed storage and delivery assembly 40 simultaneously with the wastewater and the homogenizing agent. Finally, the dosing amount control assembly 20 controls the inflow of the remaining part of the clean water alone. In the flow process, the wastewater usually contains certain impurity particles and other substances which are easy to gather in the pipeline. The last part of the clean water plays a role of thorough flushing, further flushes the impurities remaining after the treatment of the wastewater and the homogenizing agent, and ensures that the inner wall of the pipeline remains in a relatively clean state, thereby avoiding the pipeline blockage. Meanwhile, the homogeneity of the mixed liquid is improved, and the error in the detection of the mixed solid content by the mixed liquid uniformity detection assembly 31 is avoided due to the residual impurities in the wastewater on the pipeline wall.

[0038] In the embodiment of the utility model, refer to Figure 2 The wastewater storage and delivery assembly 10 includes a wastewater delivery pump 101, and the wastewater delivery pump 101 is electrically connected with the dosing amount control assembly 20. The clean water storage and delivery assembly 11 includes a clean water delivery pump 102, and the clean water delivery pump 102 is electrically connected with the dosing amount control assembly 20. The homogenizing agent storage and delivery assembly 12 includes a homogenizing agent delivery pump 103, and the homogenizing agent delivery pump 103 is electrically connected with the dosing amount control assembly 20.

[0039] The wastewater delivery pump 101, the clean water delivery pump 102 and the homogenizing agent delivery pump 103 are electrically connected with the dosing amount control assembly 20 respectively, so that the delivery of each liquid can be independently controlled. Exemplarily, the delivery pump can be selected from, for example, a centrifugal pump, a diaphragm pump and a screw pump. Secondly, different production environments have different requirements for the delivery distance and height of the mixed liquid, and the delivery pump can adjust the delivery capacity under the control of the dosing amount control assembly 20 to meet these diversified conditions.

[0040] In the embodiment of the utility model, refer to Figure 2 The concrete cleaning wastewater recycling device 1 further includes a first mixer 51, and the first mixer 51 is arranged in the wastewater storage and delivery assembly 10. The concrete cleaning wastewater recycling device 1 further includes a second mixer 52, and the second mixer 52 is arranged in the mixed storage and delivery assembly 40.

[0041] In the wastewater storage and delivery assembly 10, the components of the concrete cleaning wastewater are relatively complex, and may include cement particles, sand and stone debris and other substances. If the wastewater is in a static state, these solid particles are easy to sediment at the bottom of the storage and delivery device due to the action of gravity, resulting in the stratification of the components of the wastewater. The first mixer 51 arranged in the wastewater pool 105 can make the various components of the wastewater fully mixed and kept in a suspended state through continuous stirring, thereby effectively preventing the sedimentation of the solid particles and the stratification of the components.

[0042] When the wastewater, clean water and homogenizing agent flow into the mixed liquid tank 401, the second stirrer 52 promotes the rapid and sufficient mixing of the three liquids in a short time by generating a strong stirring flow field. At the same time, the dynamic balance of the mixed liquid is maintained, so that it is always in a state of uniform mixing, and the detection error of the mixed solid content detection assembly 31 is reduced. Exemplarily, the stirrer may, for example, be selected as a paddle stirrer or a turbine stirrer.

[0043] In the embodiment of the utility model, refer to Figure 2 As shown in the figure, the concrete cleaning wastewater recycling device 1 further comprises a liquid level detection device 60, the liquid level detection device 60 is electrically connected with the dosing quantity control assembly 20, and the liquid level detection device 60 is arranged in the mixed storage and delivery assembly 40.When the liquid level detection device 60 detects that the liquid level of the mixed liquid reaches the highest preset value, the dosing quantity control assembly 20 controls the wastewater storage and delivery assembly 10, the clean water storage and delivery assembly 11 and the homogenizing agent storage and delivery assembly 12 to stop delivering liquid to the mixed storage and delivery assembly 40.When the liquid level detection device 60 detects that the liquid level of the mixed liquid reaches the lowest preset value, the dosing quantity control assembly 20 controls the wastewater storage and delivery assembly 10, the clean water storage and delivery assembly 11 and the homogenizing agent storage and delivery assembly 12 to start delivering liquid to the mixed storage and delivery assembly 40.Exemplarily, the liquid level detection device 60 can also be arranged in the wastewater pool 105, so that the liquid level of the wastewater in the wastewater pool 105 can be viewed in real time, and the delivery amount of the dosing quantity control assembly 20 can be adjusted according to the liquid level of the wastewater.The continuity of the wastewater recycling process is maintained through accurate liquid level monitoring, the risk of mixed liquid overflow and the problem of dryness are prevented, and the production efficiency is effectively improved through automatic and accurate control.The liquid level detection device 60 can be a drop-in liquid level meter or an ultrasonic liquid level meter.

[0044] In the embodiment of the utility model, refer to Figure 3 As shown in the figure, the concrete cleaning wastewater recycling device 1 further comprises a finished product storage and delivery assembly 70, and the liquid inlet end of the finished product storage and delivery assembly 70 is connected with the liquid outlet end of the mixed storage and delivery assembly 40.The finished product storage and delivery assembly 70 provides storage function for the wastewater that meets the production standard after treatment, so that the influence of factors such as frequent delivery operation and flow fluctuation of the mixed storage and delivery assembly 40 on the density of the mixed liquid is avoided.

[0045] In the embodiment of the utility model, refer to Figure 4As shown, the mixing and storing component 40 includes multiple, and the multiple mixing and storing components 40 are parallel to each other. In mass production, multiple mixing and storing components 40 can be enabled at the same time to meet the demand of a large amount of mixed liquid; while in small-scale production or in periods of low production demand, only a part of the mixing and storing components 40 can be used, and the number of mixing and storing components 40 enabled can be flexibly adjusted to adapt to the demand fluctuation in the production process. Secondly, the multiple mixing and storing components 40 provide a redundant backup mechanism, which reduces the risk of interrupting the entire concrete production due to the failure of a single mixing and storing component 40, and improves the continuity and stability of the production.

[0046] In addition, it can be understood that the foregoing various embodiments are only exemplary descriptions of the present application, and under the premise that the technical features do not conflict, the structures are not contradictory, and the purpose of the present application is not violated, the technical solutions of each embodiment can be arbitrarily combined and used.

[0047] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of each embodiment of the present application.
