Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for engineering construction. Background Technology

[0002] Construction refers to the physical construction activities of construction companies in accordance with the requirements of construction project design documents, including the construction of new, expanded, or renovated projects. It includes the entire process of surveying, material preparation, foundation construction, structural construction, equipment installation, and decoration. During construction, water is needed for cleaning equipment, flushing pumps and pipelines, concrete curing wastewater, drilling mud, and washing construction sites. Under normal circumstances, such wastewater is discharged directly, and the impurities and mud particles contained in it cannot be effectively treated, which can easily clog discharge equipment and cause environmental pollution.

[0003] The invention disclosed in CN111995093A is a construction wastewater treatment device for building engineering. It is equipped with two inclined screens that are hinged to the outer shell and fixed between the two screens by springs. During the screening process, the screens will shake under the action of the baffle, making it easier to separate water and silt, which facilitates the filtration of the screens. At the same time, the silt will flow out from the waste outlet, preventing the silt from accumulating on the screens and causing blockage.

[0004] The utility model disclosed in CN213707951U is a wastewater treatment device for construction engineering. By setting up a fixed roller, filter holes and filter screen, the overall filtration effect of the device is improved. The multiple filtration operation improves the efficiency of wastewater treatment. By setting up a filtration device and a disinfection device, the device can better filter the wastewater, thereby further improving the efficiency of wastewater treatment and avoiding the occurrence of secondary pollution.

[0005] However, the wastewater treatment devices for engineering construction disclosed above still have the following problems in actual use: Although the filtration mechanism in the treatment device can clean up the impurities in the wastewater, such filtration mechanism does not have the corresponding impurity removal effect. After filtering the impurities, the impurities become clogged inside the filtration mechanism. At the same time, the flow rate of wastewater in the treatment device is too fast, and the particulate matter mixed inside is difficult to be effectively separated, which affects the treatment effect and efficiency in the long-term use.

[0006] Therefore, we propose an engineering construction wastewater treatment device to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an engineering construction wastewater treatment device to solve the problem that existing treatment devices use filtration mechanisms to clean impurities in wastewater, but these filtration mechanisms do not have the corresponding impurity removal effect. This is because after filtering impurities, they become clogged inside the filtration mechanism. At the same time, the flow rate of wastewater in the treatment device is too fast, making it difficult to effectively separate the particulate matter mixed inside, which affects the treatment effect and efficiency during long-term use.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an engineering construction wastewater treatment device, comprising a mixing tank and a through-type cover fixedly installed on the top of the mixing tank; further comprising:

[0009] The top of the mixing tank is equipped with a processing mechanism, which includes a flow guide box. A processing guide frame is fixedly installed inside the flow guide box, and the processing guide frame guides the wastewater.

[0010] The top of the through-cap is provided with a feeding mechanism, which includes a feeding hopper. A sealing baffle is slidably provided at the lower end of the feeding hopper. The sealing baffle intermittently feeds the treatment agent inside the feeding hopper by reciprocating sliding.

[0011] Preferably, the bottom end of the flow guide box included in the treatment mechanism is disposed at the center of the through-cover, and the flow guide box and the mixing tank are interconnected, so that the wastewater inside the flow guide box flows into the interior of the mixing tank after treatment, so that the wastewater can be mixed and treated by the mixing tank.

[0012] Preferably, the processing mechanism includes a positioning horizontal plate, which is fixedly installed on the left and right sides of the lower part of the guide box. The inner ends of the symmetrically arranged positioning horizontal plates are fixedly connected to the bottom end of the processing guide frame. Furthermore, the interior of the symmetrically arranged positioning horizontal plates is provided with guide grooves at equal intervals to facilitate the downward flow of treated wastewater.

[0013] Preferably, the processing mechanism includes a processing guide frame arranged in an isosceles trapezoidal structure, and the left and right ends of the processing guide frame are provided with separation slots at equal distances. The bottom center of the separation slots at equal distances is provided with a storage chute. The separation slots and the storage chute are distributed in a one-to-one correspondence. The separation slots are used to carry and separate impurities in the flowing wastewater, and the storage chute stores the impurities to prevent them from being washed away by the flowing wastewater.

[0014] The treatment mechanism includes a transmission bar fan rotatably mounted on the bottom surface of the positioning horizontal plate, and the outer ends of the symmetrically arranged transmission bar fans are connected to the outer ends of the reciprocating threaded rods through a pulley assembly. The treated sewage drives the transmission bar fans and the reciprocating threaded rods to rotate.

[0015] Preferably, the interior of the flow guide box includes a cleaning mechanism, which includes a reciprocating threaded rod. The reciprocating threaded rod is rotatably mounted on the left and right sides of the top surface of the flow guide box via bearings. The outer ends of the symmetrically arranged reciprocating threaded rods are all connected to positioning brackets by bearings. The positioning brackets are fixedly mounted on the front and rear sides of the exterior of the flow guide box. The reciprocating threaded rods on the left and right sides inside the flow guide box are threaded through the top of the cleaning scraper.

[0016] Preferably, the impurity removal mechanism includes an impurity removal scraper that slides in contact with the outer wall of the treatment guide frame. The back-and-forth movement of the impurity removal scraper scrapes against the impurities in the storage troughs on the left and right sides of the treatment guide frame. Furthermore, a protective top plate is provided on the top of the treatment guide frame, and the protective top plate is fixedly installed in the middle of the top surface of the guide box to prevent wastewater from affecting the normal operation of the treatment mechanism.

[0017] Preferably, the impurity removal mechanism includes impurity discharge strip holes opened on the front and rear sides inside the flow guide box, and sealing partitions are slidably arranged on the front and rear sides outside the flow guide box. The inner end of the sealing partition is slidably inserted into the interior of the impurity discharge strip holes, and the outer end of the sealing partition slides through the inner end of the limiting bracket. At the same time, the limiting bracket is fixedly installed on the outside of the flow guide box.

[0018] Preferably, the inner end of the sealing partition included in the impurity removal mechanism is slidably disposed on the outer end of the positioning bracket, and the sealing partition, the positioning bracket and the limiting bracket are interconnected by a reset spring. The sealing partition slides after being squeezed between itself and the impurity removal scraper, so that the impurities carried by the impurity removal scraper are discharged through the opened discharge strip hole, thus avoiding blockage of the processing mechanism.

[0019] Preferably, the feeding mechanism includes limiting slide grooves opened on the front and rear sides of the top of the cover, and the limiting slide grooves are symmetrically arranged with transmission slide bars slidably arranged inside each groove. The side of the symmetrically arranged transmission slide bars near the feeding hopper is fixedly connected to the sealing baffle plate, and the sealing baffle plate and the feeding hopper are connected to each other by abutment springs.

[0020] Preferably, the feeding mechanism includes an abutting lever, which is fixedly installed on the outer end of the transmission strip outside the guide box. The bottom end of the abutting lever contacts the end of the transmission slide away from the feeding hopper by rotation, so that the abutting lever drives the transmission slide to slide against the sealing baffle, thereby realizing the intermittent feeding of the feeding hopper.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This construction wastewater treatment device slows down the flow rate of wastewater during the treatment process through the treatment guide frame of the flow guide box. After the impurity particles are collected through the impurity storage chute, they are scraped off and discharged by the impurity removal scraper. At the same time, it can drive the feeding hopper to open and close repeatedly, adding the reagent and wastewater into the mixing tank, thereby improving the fusion effect and treatment efficiency of wastewater treatment. The specific details are as follows:

[0022] 1. Wastewater is fed into the upper part of the treatment guide frame inside the guide box. The inclined structure of the treatment guide frame slows down the flow speed of the wastewater. At the same time, the separation troughs on the left and right sides of the treatment guide frame are designed to bear and limit the impurity particles in the wastewater. Meanwhile, the impurity storage trough stores and collects the separated impurity particles to prevent the flowing wastewater from washing away the impurity particles and affecting the collection.

[0023] After being separated from impurities, the wastewater continues to flow downwards into the mixing tank through the guide channels inside the positioning plate. This allows the impurities in the wastewater to remain in the guide box for subsequent cleaning, preventing them from flowing with the wastewater and affecting its subsequent treatment.

[0024] 2. The positioning plate makes the flowing wastewater come into contact with the transmission bar fan, and drives the reciprocating threaded rod connected to the transmission bar fan and the pulley assembly to rotate. The reciprocating threaded rod drives the threaded scraper to slide against the outer wall of the treatment guide frame, thus moving the dirt particles stored in the separation tank and the dirt storage trough, avoiding affecting the subsequent collection effect.

[0025] The moving scraper slides outward against the sealing baffle inside the discharge bar hole, so that the scraper can push the dirt particles to the outside of the guide box after passing through the discharge bar hole, thus preventing dirt particles from remaining in the guide box and affecting wastewater treatment. At the same time, the sealing baffle is re-inserted into the discharge bar hole to prevent wastewater from overflowing and causing pollution.

[0026] 3. The rotating drive bar drives the end contact lever, which then contacts the drive slide bar and moves it to one side of the feeding hopper. The drive slide bar drives the sealing baffle to open the feeding hopper, allowing the treatment agent inside to be fed downwards into the mixing tank to treat the wastewater. Then, the contact spring drives the drive slide bar and the sealing baffle to reset and close the feeding hopper, improving the fusion treatment effect of wastewater and treatment agent.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-10 The present invention provides the following technical solution:

[0040] Example 1: To address the existing problems in the treatment of wastewater from construction projects, this example discloses the following technical solution: a construction wastewater treatment device, comprising a mixing tank 1 and a through-sealed cover 2 fixedly installed at the top of the mixing tank 1; a treatment mechanism is provided at the top of the mixing tank 1, and the treatment mechanism includes a flow guide box 3, and a treatment guide frame 4 is fixedly installed inside the flow guide box 3, which guides the wastewater; the bottom end of the flow guide box 3 is disposed through the center of the through-sealed cover 2, and the flow guide box 3 is interconnected with the mixing tank 1, so that the wastewater inside the flow guide box 3, after treatment, flows into the interior of the mixing tank 1, so that the wastewater can be mixed and treated by the mixing tank 1.

[0041] The treatment mechanism includes a positioning plate 7, which is fixedly installed on the left and right sides of the lower part of the flow guide box 3. The inner ends of the symmetrically arranged positioning plates 7 are fixedly connected to the bottom end of the treatment guide frame 4. The symmetrically arranged positioning plates 7 have flow guide slots 23 opened at equal intervals inside, which facilitates the downward flow of treated wastewater.

[0042] The treatment mechanism includes a treatment guide frame 4 arranged in an isosceles trapezoidal structure. Separation troughs 8 are equally spaced at both ends of the treatment guide frame 4. A storage trough 9 is provided in the middle of the bottom surface of each of the equally spaced separation troughs 8. The separation troughs 8 and the storage troughs 9 are distributed in a one-to-one correspondence. The separation troughs 8 are used to carry and separate impurities in the flowing wastewater, and the storage troughs 9 are used to store the impurities to prevent them from being washed away by the flowing wastewater.

[0043] like Figures 3-4 , Figure 7 As shown, during treatment, wastewater is fed into the interior of the guide box 3. The protective top plate 13 inside the guide box 3 guides the wastewater, causing it to flow slowly along the inclined structures on the left and right sides of the treatment guide frame 4. As the wastewater flows, it comes into contact with the separation trough 8 located outside the treatment guide frame 4. The separation trough 8 blocks impurities in the wastewater, while the impurity storage trough 9 located in the middle of the separation trough 8 collects the blocked impurities, causing them to settle inside the impurity storage trough 9 and preventing them from flowing with the water.

[0044] Furthermore, the inclined structure on the outside of the treatment guide frame 4 guides the water flow, allowing the filtered water to flow to the bottom of the treatment guide frame 4 and continue to flow downwards into the mixing tank 1 through the guide slot 23 opened inside the positioning horizontal plate 7, so that the impurity particles in the wastewater remain in the guide box 3 for subsequent cleaning.

[0045] Example 2: To address the problems existing in the treatment of wastewater from current engineering construction, this example discloses the following technical solution: The treatment mechanism includes a transmission fan 24 rotatably mounted on the bottom surface of the positioning horizontal plate 7. The outer ends of the symmetrically arranged transmission fan 24 and the outer ends of the reciprocating threaded rod 10 are connected to each other via a pulley assembly 18. The treated wastewater drives the transmission fan 24 and the reciprocating threaded rod 10 to rotate. The impurity removal mechanism includes an impurity removal scraper 12 that slides against the outer wall of the treatment guide frame 4. The back-and-forth movement of the impurity removal scraper 12 scrapes against the impurities in the impurity storage troughs 9 on the left and right sides of the treatment guide frame 4. A protective top plate 13 is provided on the top of the treatment guide frame 4, and the protective top plate 13 is fixedly installed in the middle of the top surface of the guide box 3 to prevent wastewater from affecting the normal operation of the treatment mechanism.

[0046] The impurity removal mechanism includes impurity discharge strip holes 14 opened on the front and rear sides inside the flow guide box 3, and sealing partitions 15 are slidably arranged on the front and rear sides outside the flow guide box 3. The inner end of the sealing partition 15 is slidably inserted into the interior of the impurity discharge strip holes 14, and the outer end of the sealing partition 15 is slidably inserted through the inner end of the limiting bracket 16. At the same time, the limiting bracket 16 is fixedly installed on the outside of the flow guide box 3.

[0047] The inner end of the sealing partition 15 included in the impurity removal mechanism is slidably disposed on the outer end of the positioning bracket 11, and the sealing partition 15, the positioning bracket 11 and the limiting bracket 16 are connected to each other by a return spring 17. The sealing partition 15 slides after being squeezed between it and the impurity removal scraper 12, so that the impurities driven by the impurity removal scraper 12 are discharged through the open discharge strip hole 14, thus avoiding blockage of the treatment mechanism.

[0048] like Figures 4-6 As shown, the filtered wastewater flows downward through the guide slot 23 in the positioning plate 7, which in turn drives the transmission bar 24 located below the positioning plate 7 to rotate. The transmission bar 24 drives the reciprocating threaded rod 10 to rotate through the pulley assembly 18 at its outer end. The impurity removal scraper 12, which is threadedly connected to the reciprocating threaded rod 10, adheres to the outer wall of the processing guide frame 4. As the impurity removal scraper 12 moves, it moves the impurity particles remaining in the separation trough 8 and the impurity storage trough 9, thus preventing the impurity particles in the processing guide frame 4 from being stored for a long time and affecting the processing effect.

[0049] Furthermore, after the scraper 12 carrying the impurity particles moves to the side of the guide box 3, it moves outward against the sealing partition 15 installed inside the discharge strip hole 14. After the sealing partition 15 opens the discharge strip hole 14, the scraper 12 slides into the discharge strip hole 14 and pushes the impurity particles it carries to the outside of the guide box 3. At the same time, the sealing partition 15 is connected to the positioning bracket 11 and the limiting bracket 16 through the return spring 17. When the scraper 12 moves back to its original position, it is re-inserted into the discharge strip hole 14 to prevent wastewater from overflowing and causing pollution.

[0050] Example 3: To address the problems existing in the treatment of wastewater from current engineering construction, this example discloses the following technical solution: A feeding mechanism is provided at the top of the through-cap 2, and the feeding mechanism includes a feeding hopper 5. A sealing baffle 6 is slidably provided at the lower end of the feeding hopper 5. The sealing baffle 6 intermittently feeds the treatment agent inside the feeding hopper 5 by reciprocating sliding. The interior of the guide box 3 includes a cleaning mechanism, and the cleaning mechanism includes a reciprocating threaded rod 10. The reciprocating threaded rod 10 is rotatably mounted on the left and right sides of the top surface of the guide box 3 by bearings. The outer ends of the symmetrically arranged reciprocating threaded rods 10 are all connected to positioning brackets 11 by bearings. The positioning brackets 11 are fixedly installed on the front and rear sides of the exterior of the guide box 3. The reciprocating threaded rods 10 on the left and right sides inside the guide box 3 are threaded through the top of the cleaning scraper 12.

[0051] The feeding mechanism includes limiting grooves 19 on both the front and rear sides of the top of the through-cover 2, and symmetrically arranged limiting grooves 19 are slidably arranged with transmission slides 20 inside each groove. The side of the symmetrically arranged transmission slides 20 near the feeding hopper 5 is fixedly connected to the sealing baffle 6, and the sealing baffle 6 and the feeding hopper 5 are connected to each other by abutment springs 21. The feeding mechanism includes abutment lever 22, which is fixedly installed on the outer end of the transmission bar fan 24 outside the guide box 3. The bottom end of the abutment lever 22 contacts the end of the transmission slide 20 away from the feeding hopper 5 by rotation, so that the abutment lever 22 drives the transmission slide 20 to slide against the sealing baffle 6, realizing the intermittent feeding of the feeding hopper 5.

[0052] like Figures 8-10As shown, during the rotation of the transmission bar fan 24 inside the guide box 3, it drives the outer fixedly connected abutment lever 22 to rotate, so that the bottom end of the abutment lever 22 contacts the transmission slide bar 20 that penetrates the top surface of the cover 2, causing it to move along the limiting slide groove 19 to one side of the feeding hopper 5. At the same time, the transmission slide bar 20 drives the fixedly connected sealing baffle 6 to move synchronously, so that the sealing baffle 6 opens the internal channel of the feeding hopper 5. After the transmission slide bar 20 disengages from the abutment lever 22, the abutment spring 21 drives the transmission slide bar 20 and the sealing baffle 6 to reset, re-closing the feeding hopper 5, so that the treatment agent inside the feeding hopper 5 can fall into the mixing tank 1 for mixing with wastewater to achieve efficient treatment.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
