Description

Technical Field

[0001] This invention relates to the field of wastewater treatment and reuse devices, specifically a device for the recycling and reuse of construction wastewater. Background Technology

[0002] Construction sites generate large amounts of wastewater due to the need for washing various mixing and pouring equipment and the construction site itself. This wastewater is collected in wastewater ponds. Direct discharge of this wastewater not only causes pollution but also wastes water resources. Therefore, wastewater treatment equipment is needed to remove the silt and sand from the wastewater and reuse it as flushing water. Generally, wastewater from the wastewater ponds is pumped into large sedimentation tanks. Through static sedimentation, the silt settles in the sedimentation tank, and the clean water is on top of the silt. Then, the clean water is pumped away for use as circulating flushing water. However, the sedimentation time in sedimentation tanks is too long, and the silt also has recycling value, such as being used for site backfilling and roadbed subbase. The sediment in the sedimentation tank is not only difficult to excavate and recycle, but also contains a lot of moisture. Even if it is recycled, it still needs to be drained before it can be used. Therefore, the existing technology sets up a filter bag device above the sedimentation tank. The sewage pump discharges sewage directly into the filter bag, and the sediment in the sewage is directly trapped in the filter bag. Since the rinsing water filtered by the filter bag is relatively clean, it does not need to spend a long time settling and can be used directly. The filter bag directly collects the sediment in the sewage, and the water in the sediment is drained out. The sediment can be extracted and used directly by removing the filter bag. However, the sediment trapped in the filter bag of the existing technology is relatively loose, resulting in a small amount of sediment that the filter bag can trap, which increases the frequency of filter bag replacement and increases the workload. Summary of the Invention

[0003] To address the technical problems mentioned in the background section, the present invention provides a construction wastewater recycling and reuse device, employing the following technical solution:

[0004] It includes a sedimentation tank and a walking platform fixed to the inner wall of the sedimentation tank. A drain pipe is connected to the bottom of the sedimentation tank, and a valve is connected to the end of the drain pipe. A filter bag device is installed at the bottom of the walking platform and is suspended above the sedimentation tank. The filter bag device includes a floating mechanism installed at the bottom of the walking platform and several filter bag mechanisms installed on the side of the walking platform. Several filter bags are placed on the filter bag mechanisms. The floating mechanism and the filter bag mechanisms are configured in cooperation.

[0005] Furthermore, the walking platform includes two beams fixed to the inner wall of the sedimentation tank, with a grid tread fixedly connected to the upper part of the beams, and a fence fixedly connected around the grid tread.

[0006] Furthermore, the floating mechanism includes a limiting rod fixed to the bottom of the grid pedal, on which a floating component is slidably mounted.

[0007] Furthermore, the floating component includes a buoy with a perforation at its center. The buoy is slidably connected to a limiting rod through the perforation. A fixing ring is fixedly connected to the outer ring of the buoy, and lugs are fixedly connected to both sides of the fixing ring. A connecting rod is fixedly connected through the center of each lug.

[0008] Furthermore, the filter bag mechanism includes a water tank fixedly connected to the side of the frame beam, with several filter holes opened in the water tank, and filter bags placed in the filter holes. Fixed plates are fixedly connected to both sides of the bottom of the water tank, and upper sliding rods and lower sliding rods are fixedly connected between the two fixed plates from top to bottom. Several evenly arranged clamping plates are slidably connected through the upper sliding rods and lower sliding rods, and the filter bags are located between the clamping plates. It also includes a driving component set in front of the clamping plates.

[0009] Furthermore, the driving component includes a round rod fixed to the front side of the clamping plate and a driving plate. The left side of the driving plate is provided with several straight slots a that are inclined to the upper left, and the right side is provided with several straight slots b that are inclined to the upper right. The straight slots a and b are respectively movably sleeved on the corresponding round rods, and the connecting rod is fixedly connected to the side of the driving plate.

[0010] Furthermore, a limiting ring is fixedly connected to the inner wall of the filter hole, and a placement ring is fixedly connected to the upper part of the filter bag. The placement ring is placed on the limiting ring and limited by the filter hole, and the filter bag passes through the filter hole and the limiting ring.

[0011] Furthermore, several branch pipes are connected through the side wall of the water tank. Each branch pipe is located at the front end of the corresponding filter hole. Several branch pipes are connected to a sewage pipe, which is connected through the sedimentation tank.

[0012] This invention has the following advantages: When wastewater enters the filter bag of the filter bag mechanism, the silt and sand in the wastewater are intercepted and retained inside the filter bag. After the silt and sand are removed, the wastewater passes through the filter bag and falls into the sedimentation tank. The water level in the sedimentation tank gradually rises. When the water level touches the bottom of the floating mechanism, the floating mechanism rises linearly, driving one end of the filter bag mechanism to rise as well. This causes the filter bag mechanism to gradually squeeze the filter bag and the silt and sand inside the filter bag from the outside inwards, compacting the silt and sand inside the filter bag. When the wastewater stops entering, the wastewater in the sedimentation tank is discharged. As the water level in the sedimentation tank decreases, the floating mechanism... As the filter bag mechanism descends, it loosens its clamping grip on the filter bag, facilitating the entry of wastewater next time. The filter bag of this invention not only intercepts silt but also utilizes the buoyancy of the wastewater in the sedimentation tank. Through the movement of the floating mechanism, the filter bag mechanism compresses the filter bag and the silt inside, compacting the silt and reducing its space ratio within the filter bag. Furthermore, by loosening the filter bag, it allows more silt to be intercepted when wastewater enters the filter bag next time. This increases the amount of silt the filter bag can hold, reducing the frequency of filter bag replacement and alleviating the workload of workers.

[0013] When the filter bag needs to be replaced, the wastewater in the sedimentation tank is discharged, and the floating mechanism descends to release the filter bag, making it easy for workers to remove the filter bag.

[0014] The floating mechanism of this invention is suspended above the sedimentation tank, so that the sewage in the sedimentation tank only comes into contact with the floating mechanism when it rises to a certain water level. This ensures that the floating mechanism only begins to rise a short distance and squeeze the filter bag when the water level in the sedimentation tank is about to reach the specified position. This avoids squeezing the filter bag as soon as water enters the sedimentation tank, which would reduce the space of the filter bag due to compression, resulting in less space for sediment and causing sewage to overflow from the top of the filter bag.

[0023] 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.

[0024] Please refer to Figure 1-7 This invention provides a construction wastewater recycling and reuse device, including a sedimentation tank 1 and a walking platform fixed to the inner wall of the sedimentation tank 1. Since the amount of wastewater generated at the construction site is large, the sedimentation tank 1 is a large sedimentation tank 1. To facilitate maintenance and the removal and placement of filter bags 3, a walking platform needs to be fixedly installed inside the sedimentation tank 1 for easy worker movement. A drain pipe 2 is connected to the bottom of the sedimentation tank 1. The drain pipe 2 is used to discharge the wastewater in the sedimentation tank 1 after removing sludge and sand, and supply it to the construction site for recycling. A valve is connected to the end of the drain pipe 2. Since the actual drain pipe 2 is very long and the valve is installed at the end, and the installation of valves on pipes is common knowledge to those skilled in the art, it is not shown in the figure.

[0025] A filter bag device is installed at the bottom of the walking platform. The filter bag device is suspended above the sedimentation tank 1. The filter bag device includes a floating mechanism installed at the bottom of the walking platform and several filter bag mechanisms installed on the side of the walking platform. Several filter bags 3 are placed on the filter bag mechanisms. The floating mechanism and the filter bag mechanisms are set together. Sewage enters the filter bags of the filter bag mechanism. The silt in the sewage is intercepted and retained in the filter bags. After the silt is removed, the sewage passes through the filter bags and falls into the sedimentation tank. The water level in the sedimentation tank gradually rises. When the water level touches the bottom of the floating mechanism, the floating mechanism rises in a straight line and drives one end of the filter bag mechanism to rise. This causes the filter bag mechanism to gradually squeeze the filter bags and the silt inside the filter bags from the outside to the inside, thus compacting the silt inside the filter bags.

[0026] The walking platform includes two beams 4 fixed to the inner wall of the sedimentation tank 1. A grid step 5 is fixedly connected to the upper part of the beams 4. The grid step 5 is made of high-strength metal and has high load-bearing capacity. When workers pick up and put down the filter bags 3, the water drained from the filter bags 3 can fall back into the sedimentation tank 1 through the grid step 5, which prevents sewage from accumulating and causing workers to slip when walking. A fence 6 is fixedly connected around the grid step 5 to facilitate workers to support themselves when walking.

[0027] The floating mechanism includes a limiting rod 7 fixed to the bottom of the grid pedal 5. A floating component is slidably mounted on the limiting rod 7. The limiting rod 7 limits the floating component so that it can only move vertically up and down.

[0028] The floating assembly includes a float 8 with a perforation 9 at its center. The float 8 is slidably connected to the limiting rod 7 through the perforation 9. A fixing ring 10 is fixedly connected to the outer ring of the float 8. Lugs 11 are fixedly connected to both sides of the fixing ring 10. A connecting rod 12 is fixedly connected through the center of the lugs 11. The float 8 drives the fixing ring 10, lugs 11 and connecting rod 12 to rise and fall on the limiting rod 7.

[0029] The filter bag mechanism includes a water trough 13 fixedly connected to the side of the frame beam 4. When the sediment in the filter bag 3 is full and causes the sewage in the filter bag 3 to overflow from the top, it will be collected by the water trough 13 to prevent the overflowing sewage from falling directly into the sedimentation tank 1. The water trough 13 has several filter holes 14, and filter bags 3 are placed in the filter holes 14. Fixed plates 15 are fixedly connected to both sides of the bottom of the water trough 13. An upper sliding rod 16 and a lower sliding rod 17 are fixedly connected from top to bottom between the two fixed plates 15. Several evenly arranged clamping plates 18 are slidably connected through the upper sliding rod 16 and the lower sliding rod 17. The clamping plates 18 are limited by the upper sliding rod 16 and the lower sliding rod 17 so that they can only move horizontally and prevent them from overturning. The filter bag 3 is located between the clamping plates 18. The mechanism also includes a driving component set in front of the clamping plates 18. When the connecting rod 12 is raised or lowered, it drives the driving component to rise or fall.

[0030] The driving component includes a round rod 19 fixed to the front side of the clamping plate 18 and a driving plate 20. The left side of the driving plate 20 is provided with several straight slots a21 that are inclined to the upper left, and the right side is provided with several straight slots b22 that are inclined to the upper right. The straight slots a21 and b22 are respectively movably sleeved on the corresponding round rod 19. The connecting rod 12 is fixedly connected to the side of the driving plate 20. When the connecting rod 12 drives the driving plate 20 to rise and fall, the driving plate 20 drives the straight slots a21 and b22 to rise and fall. The straight slots a21 and b22 drive the round rod 19 to move left and right. The round rod 19 drives the clamping plate 18 to move left and right on the upper sliding rod 16 and the lower sliding rod 17.

[0031] A limiting ring 23 is fixedly connected to the inner wall of the filter hole 14, and a placement ring 24 is fixedly connected to the upper part of the filter bag 3. The placement ring 24 is placed on the limiting ring 23 and limited by the filter hole 14. The filter bag 3 passes through the filter hole 14 and the limiting ring 23, and is placed on the limiting ring 23 by the placement ring 24, which makes it easy to pick up and put down the filter bag 3.

[0032] Several water distribution pipes 25 are connected through the side wall of the water tank 13. Each water distribution pipe 25 is located at the front end of the corresponding filter hole 14. Several water distribution pipes 25 are connected to a sewage pipe 26. The sewage pipe 26 is connected through the sedimentation tank 1. The sewage in the sewage tank enters the sewage pipe 26 and then enters the water distribution pipe 25. The sewage in the water distribution pipe 25 enters the corresponding filter bag 3.

[0033] Working principle of the invention:

[0034] Wastewater enters the distribution pipe 25 through the wastewater pipe 26. The wastewater in the distribution pipe 25 then enters its corresponding filter bag 3. The silt and sand in the wastewater are trapped in the filter bag 3. The wastewater, after silt removal, passes through the filter bag and falls into the sedimentation tank 1. The water level in the sedimentation tank 1 gradually rises. When the water level is close to the fixed level of the sedimentation tank 1, the wastewater in the sedimentation tank 1 contacts the bottom of the float 8. The float 8 rises due to the buoyancy of the rising wastewater, and the float 8 drives the fixing ring 10, the lug 11, the connecting rod 12, and... The drive plate 20 rises vertically on the limit rod 7, driving the straight groove a21 and straight groove b22 to rise. During the rise of straight groove a21, it drives the corresponding round rod 19 inside to move to the right. The aforementioned corresponding round rod 19 drives the corresponding clamping plate 18 to move to the right on the upper sliding rod 16 and lower sliding rod 17. During the rise of straight groove b22, it drives the corresponding round rod 19 inside to move to the left. The aforementioned corresponding round rod 19 drives the corresponding clamping plate 18 to move to the left. In this way, the clamping plate 18 driven by straight groove a21 and the clamping plate 18 driven by straight groove b22 move towards each other, squeezing the filter bag 3 and the mud and sand inside it, so that the mud and sand inside the filter bag 3 are compacted, making more space inside the filter bag 3. When the water level in the sedimentation tank 1 reaches the specified water level, the sewage is stopped. At this time, the valve on the drain pipe 2 is opened, and the sewage in the sedimentation tank 1 is discharged through the drain pipe 2 and supplied to the construction site for use as flushing water. As the water level drops, the float 8 and the drive plate 20 also... As the filter bag 3 descends, the clamping plate 18 loosens its grip on the filter bag 3. After the sewage in the sedimentation tank 1 is drained, the sewage pipe 26 is opened again to discharge sewage. Since the sludge in the filter bag 3 was compacted last time, more space is created. Therefore, when intercepting sludge in the sewage again, the original filter bag 3 can hold more sludge. When the sludge in the filter bag 3 reaches its load and needs to be removed, the sedimentation tank 1 is discharging sewage. The clamping plate 18 loosens its grip on the filter bag 3, and the worker can remove the filter bag 3 from the filter hole 14.

[0035] This invention is simple to operate, convenient to use, and suitable for widespread promotion and application. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
