Description

TECHNICAL FIELD

[0001] The present application relates to the field of sewage multi-stage treatment, in particular to a concrete production equipment with a sewage recycling system. BACKGROUND

[0002] The sewage recycling system in the concrete production equipment usually adopts a multi-stage treatment process, aiming to gradually remove solid particles, suspended solids, oil stains and chemicals in the wastewater, and ultimately realize the recycling of water resources. The multi-stage treatment process includes a primary treatment stage, which uses a primary sedimentation tank and a secondary sedimentation tank to achieve physical separation and sedimentation of production wastewater; a middle-stage treatment stage, which uses a sandstone separator and a slurry concentration and dewatering system to deeply purify and recycle production wastewater; and an advanced treatment stage, which uses membrane separation technology and a disinfection and sterilization module to ensure the water quality safety of the recycled water.

[0003] The prior art discloses CN118405812B sewage treatment system of concrete mixing station, when the sludge in the sedimentation tank needs to be cleaned, the piston rod driving connector of the telescopic assembly moves upward, the connector supports the upward movement of the limiting piece, until the supporting piece reaches above the sewage treatment piece, so that the sludge in the sedimentation tank is taken out of the sedimentation tank, thereby avoiding the problem that it is difficult to clean because the sludge is located at the bottom of the sedimentation tank. CN119390274B sewage treatment device for concrete mixing station is also disclosed, by setting the sewage fast-through assembly, the impurities adsorbed on the surface of the filter screen can be cleaned, the surface of the filter screen can be prevented from gradually accumulating a large amount of impurities, the filtration effect of the filter screen on the sewage in the sewage sedimentation tank is improved, which is conducive to the normal operation of the sewage treatment and enhances the sewage treatment efficiency of the device.

[0004] Due to the obvious intermittent and fluctuating characteristics of concrete production, especially during the production peak period, a large amount of wastewater will be concentrated into the sedimentation tank, causing the water flow velocity at the inlet to increase suddenly, which easily disturbs the laminar flow state in the sedimentation tank and causes the "alum running" phenomenon. This abnormal working condition not only causes the turbidity of the sedimentation tank outlet water to increase and the water quality to deteriorate, but also causes the risk of blockage of the subsequent membrane separation equipment. The present application proposes a concrete production equipment with a sewage recycling system, which can effectively inhibit the "alum running" phenomenon of the sedimentation tank, while ensuring the treatment effect of the sedimentation tank, and also reduces the risk of blockage of the subsequent membrane separation equipment.

DETAILED DESCRIPTION

[0021] The technical solutions will be described clearly and completely below in combination with the drawing of the embodiments of the present application.

[0022] Embodiment 1

[0023] Please refer to Figure 1 - Figure 12 The concrete production equipment with sewage recycling system comprises a No.1 sedimentation tank 1 and a control box. The shunt baffle 4 and the steady flow grid structure 5 located at the right side of the shunt baffle 4 are fixedly installed in the left side of the No.1 sedimentation tank 1. The sewage inlet pipe 11 is fixedly connected to the left end of the No.1 sedimentation tank 1 and is in communication with the No.1 sedimentation tank 1. The sewage inlet pipe 11 is matched with the shunt baffle 4. The steady flow grid structure 5 comprises the grid frame 51 fixedly installed in the No.1 sedimentation tank 1. The grid frame 51 is provided with a plurality of steady flow grids 52. The pressure sensing structure 6 is embedded at the left end of the lower side of the steady flow grid 52. The grid interval adjusting structure 7 is installed at the front end of the grid frame 51 to drive and control the steady flow grid 52. The control box is loaded with an intelligent coordination protection system. The intelligent coordination protection system comprises a coordination protection processing unit. The input end of the coordination protection processing unit is connected with a flow rate monitoring unit and a steady flow state feedback unit. The output end of the coordination protection processing unit is connected with a steady flow gap regulating unit. The input end of the flow rate monitoring unit is signal connected with the water flow sensor 12 installed on the sewage inlet pipe 11, the input end of the steady flow state feedback unit is signal connected with the pressure sensing structure 6, and the output end of the steady flow gap regulating unit is signal connected with the grid interval regulating structure 7. Through the cooperation of the intelligent coordination protection system, the flow distribution baffle 4 and the steady flow grid structure 5, the flow rate of the concrete sewage entering the first sedimentation tank 1 can be accurately regulated. When the flow rate is too slow, the sewage can be smoothly introduced, and when the flow rate is too fast, the speed can be reduced to stabilize the flow. This effectively adapts to the intermittence and volatility of concrete production, avoids the phenomenon of "running alum flowers" and layer flow disorder in the first sedimentation tank 1 caused by too fast water inflow, and can monitor and feedback the steady flow effect in real time by combining the application of the pressure sensing structure 6. This not only ensures the effectiveness of the speed reduction and flow stabilization, but also intelligently dynamically regulates the steady flow gap of the steady flow grid 52, significantly improves the adaptability to changes in water inflow rate, effectively prevents the water turbidity and water quality deterioration in the first sedimentation tank 1, and improves the treatment efficiency and recycling efficiency of concrete sewage.

[0024] Please refer to Figure 2 and Figure 8 The pressure sensing structure 6 includes a sensing nest 61 embedded on the left lower side of the steady flow grid 52. The sensing nest 61 is made of elastic material, such as polyurethane elastomer, nitrile rubber, and hydrogenated nitrile rubber. The sensing nest 61 is filled with a buffer medium 63, which can be any one of air, inert gas and water, and the filling saturation degree of the buffer medium 63 is 60%-70%. The buffer medium 63 can assist the elastic effect of the sensing nest 61, resist the sewage flow impacting on the sensing nest 61, and deform the sensing nest 61 when the sewage flow impact is large, so that the trigger block 62 is contacted and triggered, realizing the monitoring and feedback of the sewage flow rate. The middle part of the left and right inner walls of the sensing nest 61 is fixedly connected with the trigger block 62, and the input end of the steady flow state feedback unit is signal connected with the trigger block 62. The cooperation of the trigger block 62 and the steady flow state feedback unit can monitor and feedback the actual effect of the steady flow gap regulation of the steady flow grid 52 in real time during the speed reduction and flow stabilization process, providing data support for subsequent intelligent dynamic regulation. This not only strengthens the adaptability of the intelligent coordination protection system to the intermittence and volatility of concrete production, but also more accurately improves the control effect of the water inflow rate, effectively avoiding the layer flow disorder and "running alum flowers" phenomenon in the first sedimentation tank 1 caused by too fast flow rate, thereby significantly enhancing the stability and reliability of the sewage recycling system in treating concrete sewage.

[0025] Please refer to Figure 9 - Figure 11The front and rear ends of the steady flow grid 52 are fixedly connected with the grid rotating rods 53, the ends of the grid rotating rods 53 away from the steady flow grid 52 extend to the outside of the grid frame 51 and are rotationally connected with the grid frame 51, the grid interval adjusting structure 7 cooperates with the grid rotating rod 53 located at the front side, the front and rear inner walls of the first sedimentation tank 1 are provided with the mounting grooves which cooperate with the grid rotating rod 53 and the grid interval adjusting structure 7 respectively, and the mounting grooves are further provided with sealing gaskets, which can realize hidden installation of the grid rotating rod 53 and the grid interval adjusting structure 7, avoid direct contact of sewage with the grid rotating rod 53 and the grid interval adjusting structure 7, improve the durability of the grid rotating rod 53 and the grid interval adjusting structure 7, realize automatic control of the steady flow grid 52 through cooperation of the grid rotating rod 53 and the grid interval adjusting structure 7, and further realize the purpose of intelligent dynamic regulation and control, so as to improve the automation and intelligent level of the sewage recycling system.

[0026] Please refer to Figure 2 and Figure 9 - Figure 11 The grid interval adjusting structure 7 comprises the driving frame 71 fixedly arranged at the front end of the grid frame 51, the interval gear rack 73 slidingly arranged at the left inner wall of the driving frame 71, and the linkage gear 72 fixedly connected with the outer end of the grid rotating rod 53 and extending into the driving frame 71. The effective meshing length of the interval gear rack 73 is defined as L, the center distance between the uppermost linkage gear 72 and the lowermost linkage gear 72 is H, and the diameter of the graduation circle of the linkage gear 72 is R, wherein L satisfies the relationship L=N(H+0.5R), N is a multiple, and the value range of N is 1.3-1.5, so as to ensure that the up-down driving of the interval gear rack 73 can effectively drive the linkage gear 72 to rotate. When the interval gear rack 73 moves to the lowermost end, the linkage gear 72 drives the steady flow grid 52 to be completely opened through the grid rotating rod 53, that is, the completely opened state of the steady flow grid 52 can be maintained through the gravity of the interval gear rack 73 itself, the normal flow of sewage inflow is ensured, and the energy consumption during inflow is reduced; when the interval gear rack 73 moves to the uppermost end, the linkage gear 72 drives the steady flow grid 52 to be completely closed through the grid rotating rod 53, the interval gear rack 73 needs to be driven and controlled, so as to realize the closing of the steady flow grid 52 and the controllability of the deceleration and steady flow effect. The inner wall of the driving frame 71 is provided with an arc-shaped elastic sleeve 74, which can be made in the form of a bellows. The lower side of the right end of the arc-shaped elastic sleeve 74 is fixedly arranged on the inner wall of the driving frame 71. The lower side of the left end of the arc-shaped elastic sleeve 74 is in sliding fit with the inner wall of the driving frame 71 and is fixedly connected with the upper end of the interval rack 73. The left and right inner walls of the arc-shaped elastic sleeve 74 are both fixedly connected with driving electromagnetic blocks 75. The two driving electromagnetic blocks 75 are fixedly connected with an auxiliary elastic wire 751. The elastic effect of the auxiliary elastic wire 751 can ensure that the two driving electromagnetic blocks 75 are always away from each other and can ensure the supporting and limiting effect on the interval rack 73 under the elastic effect of the arc-shaped elastic sleeve 74. The output end of the stable flow gap regulation unit is signal connected with the driving electromagnetic blocks 75. The cooperation of the driving electromagnetic blocks 75 and the stable flow gap regulation unit can realize the reciprocating driving effect on the interval rack 73, thereby realizing the automatic regulation and control of the gap of the stable flow grid 52. This can not only ensure the effectiveness of the speed reduction and stable flow but also ensure the response speed and efficiency of the dynamic regulation and control.

[0027] Please refer to Figure 9 Figure 11 The left rear side of the arc-shaped elastic sleeve 74 is fixedly connected with a guide column. An arc-shaped guide groove is arranged on the rear inner wall of the driving frame 71. The guide column is arranged in sliding fit in the arc-shaped guide groove. The arrangement of the guide column and the arc-shaped guide groove can effectively realize the guiding effect on the driving effect of the driving electromagnetic blocks 75. This can not only ensure the driving effectiveness of the driving electromagnetic blocks 75 but also promote the effectiveness of the deformation of the arc-shaped elastic sleeve 74 to drive the interval rack 73 to move, thereby ensuring the effect of linkage. The rear end of the interval rack 73 is fixedly connected with an anti-slip block. The anti-slip block can be dovetail-shaped or T-shaped. This can not only realize cooperation with the long sliding groove to ensure the sliding effectiveness of the interval rack 73 but also effectively ensure the stability of the installation of the interval rack 73 on the driving frame 71. A long sliding groove is arranged on the rear inner wall of the driving frame 71. The shape of the long sliding groove is adapted to the change of the anti-slip block. When the anti-slip block is selected to be dovetail-shaped, the long sliding groove is a dovetail groove. When the anti-slip block is selected to be T-shaped, the long sliding groove is a T-shaped groove. The anti-slip block is arranged in sliding fit in the long sliding groove. The cooperation of the anti-slip block and the long sliding groove can realize the guiding and limiting of the moving direction of the interval rack 73 and can also limit the moving range of the interval rack 73, thereby avoiding the condition that the interval rack 73 and the linkage gear 72 are completely separated and ensuring the effectiveness of the interval rack 73.

[0028] Please refer to Figure 1 Figure 3 The input end of the coordination protection processing unit is also connected with a sewage reuse parameter unit and an instruction control unit. The input ends of the sewage reuse parameter unit and the instruction control unit are signal connected with a touch panel arranged on a control box. ​​The output end of the coordination protection processing unit is also connected with a sewage recycling display unit and an abnormal warning unit, the output end of the sewage recycling display unit is signal connected with a touch panel arranged on the control box, the output end of the abnormal warning unit is signal connected with an alarm arranged on the control box, and the technical personnel can input the related parameters of concrete production and the related parameters of concrete sewage recycling to the sewage recycling parameter unit through the touch panel, wherein the related parameters of concrete production include but are not limited to the concrete production cycle, the production capacity of a single cycle, the water consumption under the unit production capacity and the sewage quantity under the unit production capacity and the like, and the related parameters of concrete sewage recycling include but are not limited to the water inflow speed standard range, the water turbidity standard range and the sewage flow of a single cycle and the like, and the sewage recycling parameter unit transmits the parameter data to the coordination protection processing unit after conversion, and the coordination protection processing unit analyzes and processes the data, which is convenient for subsequent regulation and control application. The technical personnel input the related control instructions to the instruction control unit through the touch panel, the instruction control unit can feed back the instruction data to the coordination protection processing unit, and the coordination protection processing unit generates corresponding control action according to the instruction, such as the manual regulation and control of the gap of the steady flow grid 52 and the processing of abnormal feedback and the like. In the process of operation of the coordination protection processing unit, it transmits the related regulation and control data to the sewage recycling display unit, and the sewage recycling display unit displays the operation data of the first sedimentation tank 1, the second sedimentation tank 2 and the membrane separation equipment 3 to the technical personnel through the touch panel, and displays the related regulation and control data of the steady flow grid 52, so that the technical personnel can adaptively regulate and control the sewage recycling parameters according to the displayed data, so as to promote the stability and reliability of the sewage recycling system in processing the concrete sewage, and when abnormal data occurs in the process of operation of the coordination protection processing unit, the alarm can be started through the abnormal warning unit to warn the technical personnel, so that the technical personnel can timely process the abnormality.

[0029] Please refer to Figure 1 - Figure 12 When the sewage recycling system is applied in the concrete production equipment, the concrete sewage flows into the first sedimentation tank 1 through the sewage inflow pipe 11, first buffers and divides the concrete sewage through the shunt baffle 4, and promotes the hard impurities in the sewage to fall to the bottom of the tank, and then enters the first sedimentation tank 1 through the flow guide of the steady flow grid structure 5, effectively reduces the disturbance of the sewage to the internal laminar flow of the first sedimentation tank 1, and the water flow sensor 12 on the sewage inflow pipe 11 can monitor the inflow speed and transmit the sewage flow speed data to the coordination protection processing unit through the flow speed monitoring unit, and the coordination protection processing unit judges the inflow speed. When the water flow rate is determined to be within the normal range, the coordination protection processing unit does not produce regulatory action, and the inter-adjustment rack 73 is kept in a fully open state under the action of gravity, through the linkage gear 72 and the grid rod 53 to drive the steady flow grid 52, to ensure that the sewage can enter the first sedimentation tank 1, and improve the efficiency of sewage entering the first sedimentation tank 1.

[0030] When the water flow rate is determined to be within the normal range, the coordination protection processing unit does not produce regulatory action, and the inter-adjustment rack 73 is kept in a fully open state under the action of gravity, through the linkage gear 72 and the grid rod 53 to drive the steady flow grid 52, to ensure that the sewage can enter the first sedimentation tank 1, and improve the efficiency of sewage entering the first sedimentation tank 1.

[0031] When the sewage is limited in flow rate, the sewage continuously impacts the pressure sensing structure 6 on the steady flow grid 52, when the impact of the sewage can cause the sensing nest 61 to produce a large deformation effect, the two trigger blocks 62 in the sensing nest 61 produce abutment contact under the action of the sewage impact force, the steady flow state feedback unit transmits the triggered signal to the coordinated protection processing unit, the coordinated protection processing unit judges that the deceleration steady flow gap control is effective at this time, at the same time, in order to take into account the sewage inflow efficiency, the coordinated protection processing unit slowly opens the steady flow gap control unit, so that the steady flow gap control unit reduces the current size entering the driving electromagnetic block 75, the electromagnetic attraction between the two driving electromagnetic blocks 75 presents a slow decreasing trend, and then under the gravity action of the interval gear 73 and the elastic recovery action of the arc-shaped elastic sleeve 74 and the auxiliary elastic wire 751, the interval gear 73 slowly moves downward, under the reverse rotation of the linkage gear 72 driven by the interval gear 73, the linkage gear 72 drives the steady flow grid 52 to gradually open through the grid rotating rod 53, the blocking effect of the steady flow grid 52 on the sewage inflow gradually decreases, and in this process, the steady flow state feedback unit continuously monitors the abutment state of the trigger block 62, after the sewage impact force cannot act on the sensing nest 61, so that the two trigger blocks 62 produce continuous abutment triggering, the steady flow state feedback unit transmits the non-triggering data to the coordinated protection processing unit, the coordinated protection processing unit makes the steady flow gap control unit maintain the current current output stable, to ensure the stability of the driving electromagnetic block 75 and the interval gear 73, so that the steady flow grid 52 keeps the same inclination angle, thereby realizing the buffering of the inflow flow rate of the steady flow grid 52, and maintaining the inflow efficiency of the sewage at the same time; When the impact force of the sewage cannot cause the induction nest 61 to produce a large deformation effect, the two trigger blocks 62 in the induction nest 61 remain in a constant disengaged state, and the steady flow state feedback unit transmits a non-triggering signal to the coordination protection processing unit. The coordination protection processing unit determines that the deceleration steady flow gap regulation effect of the steady flow grid 52 is not good at this time, and transmits a slow closing regulation instruction to the steady flow gap regulation unit, so that the steady flow gap regulation unit increases the current size entering the driving electromagnetic block 75, causing the electromagnetic attraction between the two driving electromagnetic blocks 75 to change slowly in a trend of slow increase. The arc-shaped elastic sleeve 74 and the auxiliary elastic wire 751 produce a rightward shrinkage deformation, driving the interval toothed rack 73 to slowly move upwards, and then under the reverse rotation of the linkage gear 72 driven by the interval toothed rack 73, the linkage gear 72 drives the steady flow grid 52 to slowly close and rotate through the grid rotating rod 53, gradually increasing the resistance of the steady flow grid 52 to the sewage inflow. In this process, the steady flow state feedback unit continuously monitors the state of the trigger block 62. When the sewage impact gradually increases to act on the induction nest 61, causing the two trigger blocks 62 to produce abutting triggering, the steady flow state feedback unit transmits the triggering data to the coordination protection processing unit, and the coordination protection processing unit causes the steady flow gap regulation unit to maintain the current current output stable, to ensure the stability of the driving electromagnetic block 75 and the interval toothed rack 73, so that the steady flow grid 52 maintains the same inclination angle, thereby achieving the buffering of the inflow velocity of the steady flow grid 52 while maintaining the inflow efficiency of the sewage, effectively achieving dynamic regulation of the steady flow grid 52 deceleration steady flow gap, and adapting to different concrete sewage states.

[0032] Subsequently, the coordination protection processing unit continuously adapts the steady flow gap regulation unit according to the data transmitted by the steady flow state feedback unit and the flow rate monitoring unit, effectively avoiding the interference of concrete sewage flow rate fluctuations on the one-pool 1 laminar flow and causing the "alum running" phenomenon, improving the adaptability to changes in inflow velocity, preventing the turbidity of the one-pool 1 area from rising and the water quality from deteriorating, thereby improving the treatment efficiency of the concrete sewage and the recycling benefit.

[0033] In the process of dynamic regulation of the steady flow grid 52 by the coordination protection processing unit through the steady flow gap regulation unit, when it is determined that steady flow deceleration regulation is needed, the steady flow gap regulation unit has already produced a nearly closed state through the driving electromagnetic block 75 acting on the steady flow grid 52, and the steady flow state feedback unit still transmits non-triggering data of the trigger block 62 to the coordination protection processing unit, and the coordination protection processing unit determines that the gap regulation of the steady flow grid 52 is abnormal or the induction nest 61 is damaged abnormally; Or, when judging the need to release sewage into, the steady flow gap control unit by driving electromagnetic block 75 effect steady flow grid 52 has been produced nearly open state, and the steady flow state feedback unit still to the coordination protection processing unit transmission trigger block 62 trigger data, the coordination protection processing unit judges that the steady flow grid 52 gap blockage abnormality occurs at this time; Further coordination protection processing unit through the abnormal alarm unit start alarm, to the technical personnel send abnormal warning signal, and the coordination protection processing unit also through the sewage recycling display unit to the touch panel display abnormal judgment data, so that the technical personnel in a timely manner to deal with the abnormal, ensure the effect of sewage recycling system for concrete sewage treatment.

[0036] Please refer to Figure 1 - Figure 3 and Figure 12The turbidity sensor 33 is fixedly installed on the membrane separation water inlet pipe 31, and is located on the left side of the electric three-way valve 32. The input end of the sewage turbidity monitoring unit is connected with the turbidity sensor 33 in signal connection. The cooperation of the coordinated protection processing unit and the turbidity sensor 33 realizes further protection and guarantee of the membrane separation equipment 3, and plays a double protection effect in cooperation with the flow rate monitoring unit, further avoids the sewage with too high turbidity from entering the membrane separation equipment 3, and can improve the intelligent effect of the backflow reprocessing, and selects the backflow with reference to ensure the efficiency of the sewage treatment and improve the safety and stability of the continuous application of the membrane separation equipment 3.

[0037] Please refer to Figure 1 - Figure 3 and Figure 12 The output end of the sewage monitoring starting unit is connected with the turbidity sensor 33 in signal connection. The sewage monitoring starting unit can control the starting frequency of the turbidity sensor 33, which can avoid the energy loss and performance damage caused by the continuous starting of the turbidity sensor 33 while ensuring the safety of the application of the membrane separation equipment 3, so as to promote the durability of the turbidity sensor 33.

[0038] Please refer to Figure 1 - Figure 12 When the sewage inlet flow rate transmitted by the flow rate monitoring unit is high and exceeds the set range, the coordinated protection processing unit also controls the sewage monitoring starting unit to start the turbidity sensor 33 to work, and continuously monitors the turbidity of the sewage entering the membrane separation water inlet pipe 31. The turbidity sensor 33 transmits the monitoring data to the sewage turbidity monitoring unit, and the sewage turbidity monitoring unit transmits the turbidity data to the coordinated protection processing unit. The coordinated protection processing unit judges the state of the sewage entering the membrane separation water inlet pipe 31 from the second sedimentation tank 2 according to the turbidity data. When it is judged that the sewage turbidity exceeds the set value, it is judged that the "alum running flower" phenomenon occurs in the first sedimentation tank 1, and the first sedimentation tank 1 and the second sedimentation tank 2 do not effectively treat the suspended impurities, so that they cannot be introduced into the membrane separation equipment 3. The coordinated protection processing unit controls the backflow protection control unit, so that the backflow protection control unit controls the electric three-way valve 32 to introduce the sewage in the second sedimentation tank 2 into the membrane separation water inlet pipe 31. The sewage with too high turbidity is reprocessed by the backflow pipeline, the three-way shunt pipe 22 and the sedimentation water inlet pipe 21, and is introduced into the second sedimentation tank 2, so as to avoid the problem that the sewage with too high turbidity enters the membrane separation equipment 3 and causes the blockage of the membrane separation equipment 3, and effectively ensures the safety of the application of the membrane separation equipment 3. When the turbidity of the sewage is determined to be at the set value, it is determined that the sewage sedimentation treatment at the first sedimentation tank 1 and the second sedimentation tank 2 is normal, and the backflow protection control unit and the electric three-way regulating valve 32 are not controlled, so that the sewage in the second sedimentation tank 2 can effectively enter the membrane separation equipment 3 through the membrane separation inlet pipe 31.

[0039] Subsequently, when the data of normal sewage flow rate or no sewage entering transmitted by the flow rate monitoring unit is coordinated by the protection processing unit, the turbidity sensor 33 is closed and controlled by the sewage monitoring starting unit of the coordination protection processing unit, so that it does not have a continuous monitoring effect. While reducing energy consumption, it can also effectively reduce the performance damage of its continuous application, promote the durability of the turbidity sensor 33, and effectively reduce the application cost of the sewage recycling system, and promote the benefit of concrete sewage recycling.
