Description

Technical Field

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

[0002] Construction wastewater treatment is an important part of environmental protection. It involves treating the wastewater generated at construction sites to ensure that it meets discharge standards, thereby reducing pollution to the environment. In addition to the wastewater generated during concrete mixing during construction, construction wastewater also includes domestic sewage from construction workers, such as from washing, laundry, cooking, and toileting. All of these generate a certain amount of sewage. If discharged directly without treatment, it will clog pipes and pollute the environment.

[0003] Existing methods for treating construction wastewater require pretreatment to remove larger debris for subsequent sedimentation. This pretreatment typically involves using screens to block larger debris, followed by rakes to transport the debris to a waste collection area for compression. However, in practice, we've found that existing rakes can only transport plastic bottles and garbage bags to the waste collection area, causing the wastewater inside to enter with them. If this wastewater isn't properly discharged, it pollutes other areas, impacting the environment and wasting space in the subsequent waste compression process. Therefore, we propose a construction wastewater purification and treatment device. Summary of the Invention

[0004] One of the technical problems this application aims to solve is: how to discharge sewage from containers during the sewage treatment process to prevent sewage from entering other environments along with garbage, thereby avoiding sewage pollution of the environment.

[0010] Two triggering components are provided, and the two triggering components are respectively located at both ends of the rake teeth. The triggering components drive multiple cone rods to complete the pop-out and reset movements before the rake teeth contact the cleaning system, so that the multiple cone rods can reset in time after completing the piercing work of the sewage container.

[0011] In some embodiments, the guiding component includes a driving member disposed on the outside of the plurality of cone rods, which drives the corresponding cone rods to pop out. A synchronizing member is disposed on one side of the rake teeth, which controls the plurality of cone rods to pop out and reset simultaneously.

[0015] In some embodiments, the transmission component includes a transmission frame disposed on the top of the fixed plate, a transmission shaft rotatably disposed on the transmission frame, a transmission gear disposed on the outer side of the transmission shaft, a transmission plate disposed at the bottom of the synchronization plate, and a plurality of tooth grooves meshing with the transmission gears on the transmission plate.

[0016] In some embodiments, the positioning element includes a ratchet disposed on the outside of the transmission shaft, a positioning frame disposed on the fixed plate, a positioning shaft rotatably disposed on the positioning frame, ratchet teeth disposed on the outside of the positioning shaft for cooperating with the ratchet, a positioning torsion spring disposed on the outside of the positioning shaft, one end of the positioning torsion spring away from the positioning shaft disposed on the positioning frame, and a trigger plate disposed on the grid, wherein the bottom end of the trigger plate is an arc surface.

[0020] This invention has at least the following beneficial effects:

[0021] The design of the guiding and triggering components enables the cone rod to automatically pop out and reset when needed, without manual intervention, thus improving the automation level of the device. In addition, the design of the synchronizing component ensures that multiple cone rods can pop out and reset simultaneously, further improving work efficiency. The ingenious design of components such as the driving component, synchronizing component, transmission component, positioning component, and pressing component not only realizes the automatic pop-out and reset of the cone rod, but also ensures that the position of the cone rod is accurately controlled after reset, avoiding failures caused by positional deviations. The use of mechanical structures such as drive springs, transmission gears, ratchet wheels, and ratchet teeth ensures the stability and reliability of the cone rod during the pop-out and reset process.

Detailed Implementation

[0036] 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.

[0037] Example 1: Please refer to Figure 1-10 The present invention provides a technical solution: a wastewater purification and treatment device for construction projects, comprising a wastewater collection tank 1, a garbage collection tank 2, a conveying system 3, and a cleaning system 4, and further comprising:

[0038] The screen 5 is installed inside the sewage collection tank 1 to intercept garbage in the sewage;

[0039] Multiple rake teeth 6 are provided, and all multiple rake teeth 6 are set on the conveying system 3 to transport the garbage intercepted by the grid 5.

[0040] Multiple cone rods 7 are provided, and each cone rod 7 is located on one side of a corresponding rake tooth 6. The top of each cone rod 7 is conical. The cone rods 7 slide inside the rake tooth 6 and puncture the container containing sewage.

[0041] The guide component 8 is set on one side of the rake teeth 6. The guide component 8 restricts the movement direction of the multiple cone rods 7, driving the multiple cone rods 7 to move vertically up and down, thereby using the multiple cone rods 7 to puncture the container containing sewage.

[0042] There are two trigger components 9, which are respectively located at both ends of the rake teeth 6. The trigger components 9 drive multiple cone rods 7 to complete the pop-out and reset movements before the rake teeth 6 come into contact with the cleaning system 4, so that the multiple cone rods 7 can reset in time after completing the puncture work on the sewage container.

[0043] The guide assembly 8 includes a drive member 10 disposed on the outside of multiple cone rods 7, which drives the corresponding cone rods 7 to pop out. A synchronizing member 11 is disposed on one side of the rake teeth 6, which controls the multiple cone rods 7 to pop out and reset simultaneously.

[0044] The driving component 10 includes driving plates 101 respectively disposed on the outer sides of multiple cone rods 7. Each cone rod 7 has a base plate 102 at its bottom end. Each driving plate 101 has a driving spring 103 at its bottom. The rake teeth 6 have driving grooves 104 that cooperate with the cone rods 7, and the cone rods 7 are slidably disposed within the corresponding driving grooves 104. When the ratchet 131 disengages from the ratchet teeth 134, the driving springs 103 on the outer sides of the cone rods 7 simultaneously push the driving plates 101, causing them to move upwards together. The base plates 102 at the bottom ends of the cone rods 7 prevent the cone rods 7 from detaching from the fixed plate 111 due to excessive force from the driving springs 103. When the driving plates 101 are pushed upwards by the driving springs 103, the driving plates 101... 01 moves upwards, driving the corresponding cone rod 7 upwards as well. This causes the cone rod 7 to slide on the rake teeth 6 along with the corresponding drive groove 104, impacting the garbage on the top of the rake teeth 6. This causes containers that can store sewage, such as plastic bottles and garbage bags, to develop holes after being impacted by the cone rod 7, allowing the sewage inside to be discharged. When the cone rod 7 impacts harder materials such as metal or wood, the cone rod 7 will compress the drive spring 103 through the drive plate 101, causing the cone rod 7 and the drive plate 101 to retract together. This is not affected by the synchronization plate 112 and keeps it at the same height as other cone rods 7, thus reducing wear on the cone rod 7. Its function is to generate the power to push the cone rod 7, enabling the cone rod 7 to puncture containers containing sewage.

[0045] The synchronizing component 11 includes a fixed plate 111 disposed on one side of the rake tooth 6, multiple cone rods 7 are slidably disposed in the fixed plate 111, a synchronizing plate 112 is disposed above the fixed plate 111, multiple synchronizing grooves 113 are opened on the synchronizing plate 112, and multiple cone rods 7 are slidably disposed in the corresponding synchronizing grooves 113, and the tops of multiple drive plates 101 are all in contact with the bottom of the synchronizing plate 112.

[0046] The triggering component 9 includes a transmission component 12 disposed on one side of the rake teeth 6, which transmits the force generated when the synchronization plate 112 is reset. A positioning component 13 is disposed above the fixing plate 111, which controls the position of the multiple cone rods 7 after reset. A pressing component 14 is disposed on one side of the grid 5, which presses the synchronization plate 112, causing the synchronization plate 112 to drive the multiple cone rods 7 to pop out and reset.

[0047] The transmission component 12 includes a transmission frame 121 mounted on top of the fixed plate 111, a transmission shaft 122 rotatably mounted on the transmission frame 121, a transmission gear 123 mounted on the outer side of the transmission shaft 122, and a transmission plate 124 mounted at the bottom of the synchronization plate 112. The transmission plate 124 has multiple toothed grooves 125 that mesh with the transmission gear 123. When the synchronization plate 112 moves downwards, it drives the transmission plate 124 at its bottom to move downwards as well. As the transmission plate 124 moves downwards, the toothed grooves 125 on the transmission plate 124 follow the movement of the transmission plate 123. 4. As the movement downwards, the transmission gear 123 rotates. When the transmission gear 123 rotates, the transmission shaft 122 located at the center of the transmission gear 123 will rotate along with the transmission gear 123, thereby causing the ratchet 131 on the outside of the transmission shaft 122 to rotate. At this time, the ratchet 131 will lift the ratchet 134 when it rotates, and the ratchet 134 will be locked on the next tooth of the ratchet 131 under the action of the positioning torsion spring 135, so that the synchronous plate 112 will not bounce back during the descent. Its function is to limit the position of the multiple cone rods 7 when they are reset.

[0048] Positioning component 13 includes a ratchet 131 disposed on the outside of the drive shaft 122, a positioning frame 132 disposed on the fixing plate 111, a positioning shaft 133 rotatably disposed on the positioning frame 132, a ratchet 134 disposed on the outside of the positioning shaft 133 for cooperating with the ratchet 131, a positioning torsion spring 135 disposed on the outside of the positioning shaft 133, the end of the positioning torsion spring 135 away from the positioning shaft 133 disposed on the positioning frame 132, and a trigger plate 136 disposed on the grid 5, the bottom end of the trigger plate 136 being arc-shaped. When the rake teeth 6 move from bottom to top against the grid 5 and pass the trigger plate 136, the ratchet 134... The end away from the ratchet 131 will be squeezed by the trigger plate 136. Since the bottom of the trigger plate 136 is curved, the ratchet 134 squeezed by the trigger plate 136 will rotate through the positioning shaft 133. When the ratchet 134 rotates, it will release the restriction on the ratchet 131, allowing the ratchet 131 to rotate. The torsion spring set on the outside of the positioning shaft 133 can control the ratchet 134 to get stuck on the ratchet 131 again when the ratchet 134 is released from the squeeze of the trigger plate 136. Its function is to release the squeeze of the synchronization plate 112 on the multiple drive plates 101 through the cooperation of the trigger plate 136 and the ratchet 134.

[0049] The extrusion component 14 includes an extrusion frame 141 mounted on the grid 5, an extrusion shaft 142 rotatably mounted on the extrusion frame 141, an extrusion torsion spring 143 mounted on the outer side of the extrusion shaft 142, and an end of the extrusion torsion spring 143 away from the extrusion shaft 142 mounted on the extrusion frame 141. An extrusion plate 144 is mounted on the outer side of the extrusion shaft 142, and an auxiliary plate 145 is mounted on the conveying system 3. When the rake teeth 6 continue to rise and the multiple cone rods 7 have been fully reset, the synchronizing plate 112 will lift the extrusion plate 144, so that the extrusion plate 144 rotates on the extrusion frame 141 via the extrusion shaft 142. After the synchronizing plate 112 and the fixing plate 111 have completely passed the extrusion plate 144, the extrusion torsion spring 143 will control the extrusion plate 144 to reset via the extrusion shaft 142, so that the extrusion plate 144 is once again in contact with the auxiliary plate 145. Its function is to provide extrusion force for the reset of the multiple cone rods 7.

[0050] When in use, when it is necessary to discharge the garbage and debris in the garbage collection trough 2, the conveying system 3 is started. When the conveying system 3 is turned on, the conveying system 3 will drive the rake teeth 6 to move, and make the rake teeth 6 closest to the grid 5 move from bottom to top, so that the garbage intercepted by the grid 5 is dragged up by the rake teeth 6 until the end of the ratchet 134 away from the ratchet 131 contacts the trigger plate 136.

[0051] When the rake tooth 6 moves upward from bottom to top against the grid 5 and passes the trigger plate 136, the end of the ratchet tooth 134 away from the ratchet wheel 131 will be squeezed by the trigger plate 136. Since the bottom end of the trigger plate 136 is curved, the ratchet tooth 134 squeezed by the trigger plate 136 will rotate through the positioning shaft 133. When the ratchet tooth 134 rotates, it will release the restriction on the ratchet wheel 131, allowing the ratchet wheel 131 to rotate. The torsion spring set on the outside of the positioning shaft 133 can control the ratchet tooth 134 to lock onto the ratchet wheel 131 again when the ratchet tooth 134 is released from the squeeze of the trigger plate 136. After the ratchet wheel 131 is released from the restriction of the ratchet tooth 134, the drive springs 103 on the outside of the multiple cone rods 7 will simultaneously push the drive plate 101, causing the multiple drive plates 101 to move upward together. The bottom plate 102 set at the bottom end of the cone rod 7 can prevent the ratchet tooth 134 from being squeezed by the trigger plate 136. Excessive force of the drive spring 103 causes the cone rod 7 to detach from the fixed plate 111. When the drive plate 101 is pushed upward by the drive spring 103, the drive plate 101 moves upward and drives the corresponding cone rod 7 upward as well. This causes the cone rod 7 to slide on the rake tooth 6 along with the corresponding drive groove 104 and impact the garbage on the top of the rake tooth 6. This causes containers such as plastic bottles and garbage bags that can store sewage to have holes after being impacted by the cone rod 7, thus draining the sewage inside. When the cone rod 7 impacts garbage of harder materials, such as metal or wood, the cone rod 7 will squeeze the drive spring 103 through the drive plate 101, causing the cone rod 7 and the drive plate 101 to retract together without being affected by the synchronization plate 112. It will maintain the same height as other cone rods 7, thereby reducing wear on the cone rod 7.

[0052] After the cone rod 7 pops out and punctures the container filled with sewage, the rake tooth 6 will continue to rise under the action of the conveying system 3 until the ratchet 134 disengages from the pressure of the trigger plate 136. When the ratchet 134 disengages from the pressure of the trigger plate 136, the positioning torsion spring 135 will control the ratchet 134 to reset in time through the positioning shaft 133. At this time, the rake tooth 6 is still moving upward until the synchronous plate 112 is pressed by the pressing plate 144. When the pressing plate 144 contacts the synchronous plate 112, the pressing torsion spring 143 on the outside of the pressing shaft 142 has a large elastic force, which makes the pressing plate 144... 44 will not rotate immediately after contacting the synchronization plate 112, thus causing the synchronization plate 112 to move downwards. When the synchronization plate 112 moves downwards, it will squeeze multiple drive plates 101, causing multiple cone rods 7 to move downwards under the action of the corresponding drive plates 101, thereby achieving the effect of resetting the cone rods 7. When the synchronization plate 112 moves downwards, it will drive the transmission plate 124 at its bottom to move downwards together. When the transmission plate 124 moves downwards, the tooth grooves 125 on the transmission plate 124 will follow the transmission plate 124. As the 24 moves downward, the transmission gear 123 rotates. When the transmission gear 123 rotates, the transmission shaft 122, located at the axis of the transmission gear 123, rotates along with the transmission gear 123, causing the ratchet 131 on the outside of the transmission shaft 122 to rotate. At this time, the ratchet 131 will lift the ratchet 134 when it rotates, and the ratchet 134 will be locked onto the next tooth of the ratchet 131 under the action of the positioning torsion spring 135, so that the synchronous plate 112 will not bounce back during the descent. When the rake tooth 6 continues to rise and the multiple cone rods 7 have been completely reset... At that time, the synchronous plate 112 will lift the extrusion plate 144, so that the extrusion plate 144 rotates on the extrusion frame 141 through the extrusion shaft 142. After the synchronous plate 112 and the fixed plate 111 have completely passed the extrusion plate 144, the extrusion torsion spring 143 will control the extrusion plate 144 to reset through the extrusion shaft 142, so that the extrusion plate 144 will once again fit with the auxiliary plate 145. When the rake tooth 6 reaches below the cleaning system 4, the cleaning system 4 will automatically scrape off the garbage on the rake tooth 6 and collect the garbage in a unified manner. This is the prior art and will not be described in detail here.

[0053] Example 2: Please refer to Figure 11-13 The present invention provides a technical solution:

[0054] The rake teeth 6 are equipped with multiple cutting elements 15. These multiple cutting elements 15 are used to cut debris entangled between the grid 5 and the rake teeth 6. Each cutting element 15 includes two cutting plates 151 on the rake teeth 6. Each cutting plate 151 has a sliding groove 152. A cutting shaft 153 is slidably disposed in the two sliding grooves 152. A cutting blade 154 is disposed on the outside of the cutting shaft 153. The grid 5 has a cutting groove 155 that cooperates with the cutting blade 154. When the rake teeth 6 move upward, the cutting plates 151 on the rake teeth 6 move upward along with the rake teeth 6. This causes the cutting shaft 153 sliding on the cutting plate 151 and the cutting blade 154 on the outside of the cutting shaft 153 to move upward together. At this time, the cutting blade 154 rolls on the cutting groove 155. Its function is to drive the cutting blade 154 to move together through the cutting plate 151.

[0055] The rake teeth 6 are equipped with adjusting members 16, and multiple adjusting members 16 are provided. The distance between the cutting blades 154 is automatically adjusted by using multiple adjusting members 16. Adjusting frames 161 are provided at both ends of the cutting shaft 153. The ends of the two adjusting frames 161 away from the cutting shaft 153 are provided with limiting plates 162 through a rotating shaft. The rake teeth 6 are provided with limiting grooves 163 that cooperate with the two limiting plates 162. Adjusting plates 164 are provided on the opposite sides of the two cutting plates 151. Adjusting springs 165 are provided at the bottom of the two adjusting plates 164. The ends of the two adjusting springs 165 away from the two adjusting plates 164 are provided on the top of the corresponding limiting plates 162.

[0056] During use, when the rake tooth 6 moves upward, the cutting plate 151 mounted on the rake tooth 6 moves upward along with the rake tooth 6, causing the cutting shaft 153 sliding on the cutting plate 151 and the cutting blade 154 on the outside of the cutting shaft 153 to move upward together. At this time, the cutting blade 154 rolls on the cutting groove 155. When the cutting blade 154 comes into contact with the garbage wrapped around the grid 5, such as wool or rope, the cutting blade 154 will cut it to avoid affecting the normal operation of the rake tooth 6. When encountering some harder materials, the cutting blade 154 will slide in the sliding groove 152 through the cutting shaft 153, causing the cutting blade 154 to retract and avoid damage to the cutting blade 154. After passing through a harder material, the adjusting spring 165 will pull the limiting plate 162 upward, causing the limiting plate 162 to slide in the limiting groove 163, and causing the adjusting bracket 161 rotating on the limiting plate 162 to push the cutting shaft 153, thereby causing the cutting blade 154 to return to its original position.
