DETAILED DESCRIPTION

[0047] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0048] The utility model relates to a water collection and purification treatment device for a prefabricated beam yard, such as Figures 1 to 6 As shown, including:

[0049] The coagulation box 1 is independently fixed and is the main component of the device. It can be made of high-strength materials with good corrosion resistance. A cavity is arranged inside the coagulation box 1, and a notch connected to the cavity is arranged at the top to facilitate the addition of coagulant. The size of the coagulation box 1 can be customized according to actual needs to adapt to prefabricated beam yards of different sizes;

[0050] The sealing cover 2 is arranged at the notch of the coagulation box 1 and fixed by bolts or buckles to ensure the sealing effect. The sealing cover 2 is provided with an addition port for adding coagulant into the coagulation box 1, and a baffle plate 3 is rotatably arranged at the addition port. The baffle plate 3 is closed and sealed to avoid the loss of materials during the processing. When adding materials is required, the baffle plate 3 can be opened manually;

[0051] Two stirring shafts 4 are rotatably disposed in two shaft holes provided on the sealing cover 2, respectively. Sealing rings are provided around the shaft holes to prevent water leakage. Multiple groups of stirring paddles 5 are equidistantly disposed on the stirring shafts 4 to promote the coagulation reaction.

[0052] Two transmission gears 6 are coaxially arranged on the stirring shaft 4, and the two transmission gears 6 are meshed and connected, thereby driving the two stirring shafts 4 to rotate synchronously in opposite directions, so that the purified water generates different driving forces and increases the mixing with the coagulant;

[0053] The supporting mechanism 7 is arranged at the bottom end of the coagulation tank 1 and is used for the stable placement of the coagulation tank 1. It can be adjusted according to the actual ground conditions to ensure the stable placement of the coagulation tank 1.

[0054] The driving mechanism 8 is arranged on the sealing cover 2. The driving mechanism 8 is used to provide rotational power for the two stirring shafts 4.

[0055] The adjusting mechanism 9 is arranged on the sealing cover 2. The adjusting mechanism 9 is used to switch the meshing between the driving mechanism 8 and the two stirring shafts 4, and adjust the rotation speed of the stirring shafts 4 to meet the stirring requirements under different working conditions.

[0056] The working principle of the water treatment flocculation process of this device is as follows:

[0057] The wastewater to be treated is introduced into the coagulation tank 1. The coagulant is added through the addition port on the sealing cover 2. After the addition is completed, the addition port is sealed by the baffle plate 3. The coagulation process is divided into two stages of stirring, and the driving mechanism 8 is started:

[0058] First, the adjusting mechanism 9 meshes with one stirring shaft 4 to drive the stirring paddle 5 on the stirring shaft 4 to rotate rapidly. At the same time, the other stirring shaft 4 and the stirring paddle 5 thereon are driven to rotate through the transmission gear 6, so as to fully mix the wastewater and the coagulant, aiming to quickly disperse the coagulant.

[0059] After that, the adjusting mechanism 9 is switched to mesh with the other stirring shaft 4 to drive the stirring paddle 5 on the stirring shaft 4 to rotate slowly. At the same time, the other stirring shaft 4 and the stirring paddle 5 thereon are driven to rotate through the transmission gear 6, aiming to gradually increase the flocs and prepare for the subsequent sedimentation or flotation.

[0060] After the stirring is completed, the driving mechanism 8 is turned off, and the impurities in the wastewater are waited to precipitate. Finally, the purified water is discharged from the bottom of the coagulation tank 1 to complete a water treatment cycle.

[0061] Through the design of the unique double stirring shaft 4 and transmission gear 6 structure, the coagulant and the wastewater can be mixed more evenly and quickly, improving the speed and efficiency of the coagulation reaction, shortening the water treatment time. The staged stirring method (fast first and then slow) helps the coagulant to form stable flocs in the wastewater, which not only promotes the effective aggregation of suspended particles but also provides better conditions for the subsequent sedimentation or flotation operations, thereby improving the quality of water purification.

[0062] The adjusting mechanism 9 can be implemented by mechanical or hydraulic adjusting mechanisms and other existing technologies, but these existing technologies can only achieve simple one-way speed adjustment functions and cannot flexibly switch functions between different stirring speeds. In this device, a smooth switch between fast stirring and slow stirring needs to be achieved during the coagulation process to meet the coagulation requirements at different stages. To solve the above problems, a more optimized adjusting mechanism 9 is designed in this device, as Figures 3 to 5 shown, including:

[0063] The mounting column 91 is arranged on the sealing cover 2 and serves as the support foundation of the adjusting mechanism 9;

[0064] The adjusting member 92 is rotatably arranged on the mounting column 91 through components such as bearings, and the rotation axis of the adjusting member 92 is parallel to the rotation axis of the stirring shaft 4 for easy meshing with different stirring shafts 4;

[0065] The connecting shaft 93 is arranged in the fixing groove provided on the adjusting member 92 to ensure the synchronous movement of the connecting shaft 93 and the adjusting member 92;

[0066] The first gear 94 is rotatably arranged on the connecting shaft 93, and the rotation axis of the first gear 94 is parallel to the rotation axis of the stirring shaft 4;

[0067] The second gear 95 is arranged on a stirring shaft 4, and the second gear 95 is meshed and connected with the first gear 94. The number of teeth and modulus of the second gear 95 need to match those of the first gear 94 to ensure the transmission efficiency;

[0068] The third gear 96 is arranged on another stirring shaft 4, and the third gear 96 is meshed and connected with the first gear 94. The number of teeth and modulus of the third gear 96 also need to match those of the first gear 94, and the number of teeth of the third gear 96 is different from that of the second gear 95 to achieve the speed switching of the stirring shaft 4;

[0069] The locking mechanism 97 is arranged on the mounting column 91 and is used to lock the connection position between the adjusting member 92 and the mounting column 91 to ensure the stability of the adjusting member 92 at different positions;

[0070] The transmission mechanism 98 is arranged on the mounting column 91, and the transmission mechanism 98 is used to drive the mechanism 8 to drive the first gear 94 to rotate;

[0071] The working principle of the adjusting mechanism 9 of this device is as follows:

[0072] First, manually adjust the position of the adjusting member 92 so that the first gear 94 meshes with the second gear 95 on a stirring shaft 4. Start the driving mechanism 8. The driving mechanism 8 drives the first gear 94 to rotate through the transmission mechanism 98. The rotation of the first gear 94 drives a stirring shaft 4 and the stirring paddle 5 thereon to rotate rapidly through the meshing with the second gear 95;

[0073] After the rapid stirring is completed, adjust the position of the adjusting member 92 again so that the first gear 94 meshes with the third gear 96 on the other stirring shaft 4. Start the driving mechanism 8 again. The first gear 94 rotates, but at this time, through the meshing with the third gear 96, it drives the other stirring shaft 4 and the stirring paddle 5 thereon to rotate slowly. Due to the meshing action of the two transmission gears 6, the first stirring shaft 4 and the stirring paddle 5 thereon will also rotate slowly in the reverse direction synchronously, so as to realize slow stirring, gradually increase the flocs, and prepare for subsequent sedimentation or flotation;

[0074] The design of the adjusting mechanism 9 enables the operator to change the rotation speed of the stirring shaft 4 through simple manual adjustment, without complex mechanical disassembly or electrical control, greatly improving the convenience and efficiency of operation. By adjusting the position of the adjusting member 92, the switching between rapid stirring and slow stirring can be easily realized, adapting to the requirements of stirring speed under different working conditions, and enhancing the application range and flexibility of the equipment.

[0075] The transmission mechanism 98 can be realized by using existing technologies such as chain drive and belt drive. However, these existing technologies can only achieve simple single-direction power transmission functions and cannot maintain efficient and stable power transmission under high loads and complex working conditions. In this device, efficient and stable power transmission needs to be realized during the coagulation process, and at the same time, it can smoothly switch between different stirring speeds. To solve the above problems, a more optimized transmission mechanism 98 is designed in this device, as Figures 3 to 5 shown, including:

[0076] A hollow shaft 98a is coaxially and rotatably arranged on the mounting column 91, and the rotation axis of the hollow shaft 98a is parallel to the rotation axis of the first gear 94. The design of the hollow shaft 98a needs to ensure that it can rotate freely on the mounting column 91 and has sufficient strength and stiffness to withstand the transmitted torque;

[0077] A fourth gear 98b is coaxially arranged on the hollow shaft 98a. The fourth gear 98b is respectively connected to the first gear 94 and the driving mechanism 8. The number of teeth and module of the fourth gear 98b are matched with the output gear of the first gear 94 and the driving mechanism 8. The function of the fourth gear 98b is to transmit the power of the driving mechanism 8 to the first gear 94;

[0078] The working principle of the transmission mechanism 98 of this device is as follows:

[0079] When the drive mechanism 8 is started, the gear on its output shaft begins to rotate. The fourth gear 98b meshes with the output gear of the drive mechanism 8 to receive power, and the fourth gear 98b transmits the power to the first gear 94, causing the first gear 94 to start rotating;

[0080] Through the design of the fourth gear 98b and the hollow shaft 98a, it is ensured that the power of the drive mechanism 8 can be efficiently and stably transmitted to the first gear 94, reducing energy loss.

[0081] The locking mechanism 97 can be realized by using existing technologies such as screw locks or snap locks. However, these existing technologies can only achieve simple single-point locking functions, cannot maintain a stable locking effect under high vibration and complex working conditions, and the operation is relatively cumbersome. In this device, during the coagulation process, it is necessary to quickly and reliably lock the position of the adjusting member 92 and be able to maintain stability under high vibration and complex working conditions. To solve the above problems, a more optimized locking mechanism 97 is designed in this device, as Figures 3 to 5 shown, including:

[0082] The positioning post 97a is arranged on the adjusting member 92 and serves as the support foundation of the adjusting mechanism 9. The positioning post 97a is coaxially arranged with the mounting post 91, and a blocking member 97b is arranged at the top of the positioning post 97a;

[0083] The moving member 97c is arranged on the positioning post 97a, and the moving member 97c is slidably arranged along the length direction of the positioning post 97a;

[0084] The positioning pin 97d is arranged on the moving member 97c, and the positioning pin 97d is slidably arranged in the guiding groove arranged on the mounting post 91. Positioning holes are arranged at the meshing positions of the first gear 94 and the second gear 95, and the meshing position of the first gear 94 and the third gear 96. The positioning pin 97d is inserted and pulled out from the positioning hole. A chamfer is arranged on the positioning pin 97d to facilitate insertion into the positioning hole;

[0085] One end of the spring 97e is arranged on the moving member 97c, and the other end is arranged on the blocking member 97b. The spring 97e is used to provide a reset force after the displacement of the moving member 97c and ensure the stable cooperation between the positioning pin 97d and the positioning hole;

[0086] The working principle of the locking mechanism 97 of this device is as follows:

[0087] Locking: Release the moving member 97c, and the elastic force of the spring 97e pushes the moving member 97c back to its original position, causing the positioning pin 97d to be inserted into the positioning hole, thereby locking the position of the adjusting member 92 and ensuring the meshing of the first gear 94 with the second gear 95 or the third gear 96 on one of the stirring shafts 4;

[0088] Unlock it. Pull the moving part 97c by hand to disconnect it from the positioning hole. The positioning pin 97d slides along the guiding groove. After the angle is adjusted, release the moving part 97c to lock it.

[0089] The position adjustment and locking of the adjusting part 92 can be realized through simple manual operations, without complex mechanical disassembly or electrical control.

[0090] As a preferred solution, as Figure 1 shown, an isolating part 99 is provided on the sealing cover 2. The transmission mechanism 98 is arranged inside the isolating part 99, and the locking mechanism 97 is located outside the cavity of the isolating part 99.

[0091] The isolating part 99 completely wraps the transmission mechanism 98 inside to prevent external pollutants such as dust and moisture from entering, ensuring the normal operation of the transmission mechanism 98. The locking mechanism 97 is arranged outside the isolating part 99, and the operator can directly manually adjust and lock the adjusting part 92 without disassembling the isolating part 99, improving the operation convenience.

[0092] As a preferred solution, as Figures 1 to 5 shown, the driving mechanism 8 includes:

[0093] A supporting part 81, arranged on the sealing cover 2, providing an installation basis for the driving mechanism.

[0094] A driving motor 82, arranged on the supporting part 81, providing rotational power for the stirring shaft 4, and the output end of the driving motor 82 is rotationally connected to the sealing cover 2.

[0095] A power gear 83, arranged at the output end of the driving motor 82. The power gear 83 is meshed and connected with the fourth gear 98b to transmit the power of the driving motor 82 to the transmission mechanism 98.

[0096] The working principle of the driving mechanism 8 of this device is as follows:

[0097] The driving motor 82 converts electrical energy into mechanical energy through the meshing connection between the power gear 83 and the fourth gear 98b, providing the rotational power required by the stirring shaft 4. The supporting part 81 ensures the stable installation of the driving motor 82, avoiding displacement caused by vibration or external force, and ensuring the long-term stable operation of the driving mechanism 8.

[0098] As a preferred solution, as Figure 1 and Figure 2 shown, the supporting mechanism includes:

[0099] A base 71, provided with a positioning groove, and the concrete tank 1 is arranged in the positioning groove of the base 71.

[0100] The supporting foot group 72 is arranged on the base 71. The supporting foot group 72 is provided with at least three adjusting feet, which are used to adjust the height according to the actual ground conditions to ensure the stable placement of the concrete box 1.

[0101] The working principle of the supporting mechanism 7 of this device is as follows:

[0102] The positioning groove on the base 71 matches the shape of the bottom of the concrete box 1 to ensure that the concrete box 1 can be stably placed on the base 71. Each adjusting foot of the supporting foot group 72 can independently adjust the height and make fine adjustments according to the actual ground conditions to ensure the horizontal placement of the concrete box 1. The design of the supporting foot group 72 enables the concrete box 1 to adapt to various ground conditions, including cement ground, muddy ground, etc., improving the application range of the device.

[0103] As a preferred solution, as Figure 1 shown, the top end of the concrete box 1 is provided with a liquid inlet pipe 11 for introducing the wastewater to be treated into the concrete box 1, and the bottom end is provided with a liquid outlet pipe 12, which is connected to the discharge point of the purified water through a pipeline to ensure that the purified water can be discharged smoothly. Valves 13 are respectively arranged at the liquid inlet pipe 11 and the liquid outlet pipe 12. By manually or automatically controlling the opening and closing states of the valves 13, the flow of the liquid can be precisely controlled.

[0104] The working principle of this device is as follows:

[0105] Introduce wastewater: Open the valve 13 at the liquid inlet pipe 11, introduce the wastewater to be treated into the concrete box 1 through the liquid inlet pipe 11, open the addition port on the sealing cover 2, add the coagulant, then close the addition port and seal it. Start the driving mechanism 8, adjust the rotation speed of the stirring shaft 4 through the adjusting mechanism 9 for rapid stirring and slow stirring. After the stirring is completed, close the driving mechanism 8 and wait for the impurities in the wastewater to precipitate. Open the valve 13 at the liquid outlet pipe 12 and discharge the purified water from the bottom of the concrete box 1 to complete a water treatment cycle.
