Description

Technical Field

[0001] This utility model relates to the field of photovoltaic wastewater technology, and in particular to a PAM dosing device for photovoltaic wastewater flocculation tanks. Background Technology

[0002] Photovoltaic wastewater contains a variety of pollutants, including inorganic and organic pollutants. Inorganic pollutants include silicon powder, metal ions (iron, nickel, copper, silver, sodium, aluminum, etc.), and acid radical ions (nitrate, fluoride, etc.). Organic pollutants include polyethylene glycol, organic matter in cleaning agents, and organic matter in flux.

[0003] A search revealed that patent CN214457076U discloses a PAM uniform dosing device for wastewater treatment. This technical solution has the following problems:

[0004] In existing methods, when adding PAM to the flocculation tank of photovoltaic wastewater, it is not easy to control the amount of PAM added, and it cannot achieve uniform diffusion after being added to the flocculation tank, which will affect the reaction effect and reduce the applicability.

[0005] To address the aforementioned issues, this utility model document proposes a PAM dosing device for photovoltaic wastewater flocculation tanks. Utility Model Content

[0006] This invention provides a PAM dosing device for photovoltaic wastewater flocculation tanks, which solves the shortcomings of the prior art, such as the difficulty in controlling the amount of PAM added to the photovoltaic wastewater flocculation tank, and the inability to achieve uniform diffusion after addition, which affects the reaction effect and reduces applicability.

[0007] This utility model provides the following technical solution:

[0008] The PAM dosing device for photovoltaic wastewater flocculation tank includes:

[0009] The flocculation tank body has a movable frame on its top and multiple mixing rods fixedly installed on the bottom side of the movable frame. The outer wall of each mixing rod is rotatably connected to a stirring frame via a rotating shaft.

[0010] The dispensing mechanism is set on the moving frame to evenly dispense and add PAM;

[0011] The moving mechanism is installed on the flocculation tank body and is used to move the moving frame.

[0012] In one possible design, the dispensing mechanism includes a dispensing box, an outlet, a rotating block, a limiting groove, a limiting block, a locking screw, a screw hole, a secondary gear, a main gear, and a second motor. The dispensing box is located on the top of the moving frame and is used to store PAM. Multiple outlets are opened on the outside of the dispensing box for discharging PAM.

[0013] In one possible design, the second motor is fixedly mounted on one side of the movable frame, and the output end of the second motor passes through one side of the movable frame and extends into the interior of the movable frame. The output end of the second motor is fixed to one side of the main gear through a coupling. A rotating rod is rotatably connected between the two sides of the inner wall of the movable frame through a rotating shaft. The rotating block is fixedly set on the outer wall of the rotating rod, and the secondary gear is fixedly set on the outer wall of the rotating rod and meshes with the main gear.

[0014] In one possible design, the limiting block is fixedly mounted on the bottom side of the feeding box, the limiting groove is opened on one side of the rotating block for the limiting block to be engaged, the locking screw is threadedly connected to the inside of one side of the rotating block, and the screw hole is opened on one side of the limiting block for the locking screw to be threadedly locked.

[0015] In one possible design, the movable mechanism includes a threaded block, a movable block, a first motor, a lead screw, a fixed plate, a limiting rod, a pulley, and a sliding groove. The threaded block and the movable block are respectively fixedly disposed on both sides of the movable frame. The first motor is fixedly installed on one side of the flocculation tank body. The output end of the first motor is fixed to one end of the lead screw through a coupling. The threaded block is threadedly connected to the outer wall of the lead screw.

[0016] In one possible design, both fixed plates are fixedly mounted on one side of the flocculation tank body, the limiting rod is fixedly mounted on both sides of the two fixed plates, the movable block has a sliding hole that is slidably connected to the outer wall of the limiting rod, the four pulleys are fixedly mounted on the bottom side of the movable frame, and the two sliding grooves are opened on the top side of the flocculation tank body for the pulleys to slide and limit their movement.

[0017] In this application, when PAM needs to be added, PAM is first stored in the addition box. Then, the second motor is turned on and runs, driving the main gear to rotate through the coupling. The main gear meshes with the secondary gear, thereby driving the rotating rod and rotating block to rotate. The addition box is set on the rotating block. When the rotating block rotates, it will drive the addition box to rotate, so that the PAM in the addition box will be periodically discharged from the outlet and come into contact with the liquid in the flocculation tank, thereby achieving the effect of intermittent addition of PAM. This makes it easy to control the amount of PAM added, achieves uniform diffusion, and improves the reaction effect. The rotating block has a limit groove, and the bottom side of the addition box is fixed with a limit block that fits into the limit groove. When the limit block slides onto the rotating block, the locking screw is rotated and locked into the threaded hole on the limit block, thereby locking the addition box onto the rotating block to facilitate the rotation effect and improve applicability.

[0018] Next, the first motor is started. After the first motor starts, it drives the lead screw to rotate through the coupling. Since the threaded block is threadedly connected to the outer wall of the lead screw, the rotation of the lead screw is converted into the linear movement of the threaded block. This allows control of the moving frame's speed and direction, thereby achieving precise control of the PAM dosing position and further expanding the dosing range, which is beneficial for improving the uniformity of dosing. At the same time, the moving block is slidably connected to the limiting rod through the internal sliding hole, which plays a guiding and stabilizing role. The pulley cooperates with the sliding groove to further restrict the moving frame's direction of movement, ensuring that it can only move along a specific path, thus improving stability. Multiple mixing rods are fixed on the bottom side of the moving frame. The outer wall of each mixing rod is rotatably connected to a stirring frame through a rotating shaft. When the moving frame moves, the stirring frame moves with the mixing rods and stirs the liquid in the flocculation tank. This not only helps the rapid dissolution and dispersion of PAM, but also promotes the collision, aggregation, and sedimentation of particles and impurities in the liquid, thereby improving the flocculation effect.

[0019] In this invention, the photovoltaic wastewater flocculation tank PAM dosing device can drive the dosing box to rotate through the dosing mechanism, so that the PAM in the dosing box will be periodically discharged from the outlet and come into contact with the liquid in the flocculation tank, thereby achieving the effect of intermittent addition of PAM, which makes it easy to control the amount of PAM added, can achieve uniform diffusion, and improve the reaction effect.

[0020] In this utility model, the photovoltaic wastewater flocculation tank PAM dosing device can control the moving speed and direction of the moving frame through a movable mechanism, thereby achieving precise control of the PAM dosing position, further expanding the dosing range, and helping to further improve the uniformity of dosing.

[0021] In this invention, the dispensing box can be rotated to achieve intermittent dispensing of PAM, which facilitates control of the amount of PAM added, enables uniform diffusion, and improves the reaction effect. At the same time, the moving speed and direction of the moving frame can be controlled, which is conducive to further improving the uniformity of dispensing. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0029] Please refer to Figures 1-4 The dosing device includes:

[0030] The flocculation tank body 1 has a movable frame 2 on its top and multiple mixing rods 21 fixedly installed on the bottom side of the movable frame 2. The outer wall of each mixing rod 21 is rotatably connected to a stirring frame 22 via a rotating shaft. When the movable frame 2 moves, the stirring frame 22 moves along with the mixing rods 21 and stirs the liquid in the flocculation tank. This not only helps to dissolve and disperse PAM quickly, but also promotes the collision, aggregation and sedimentation of particles and impurities in the liquid, thereby improving the flocculation effect.

[0031] The dosing mechanism, mounted on the movable frame 2, is used to uniformly add PAM. The dosing mechanism includes a dosing box 11, an outlet 12, a rotating block 13, a limiting groove 14, a limiting block 15, a locking screw 16, a screw hole 17, a secondary gear 18, a main gear 19, and a second motor 20. The dosing box 11 is located on the top of the movable frame 2 and is used to store PAM. Multiple outlets 12 are opened on the outside of the dosing box 11 for PAM discharge. The PAM in the dosing box 11 will be periodically discharged from the outlets 12 and come into contact with the liquid in the flocculation tank, thereby achieving the effect of intermittent PAM addition and facilitating the control of the PAM addition amount.

[0032] The second motor 20 is fixedly installed on one side of the movable frame 2. The output end of the second motor 20 passes through one side of the movable frame 2 and extends into the interior of the movable frame 2. The output end of the second motor 20 is fixed to one side of the main gear 19 through a coupling. A rotating rod is rotatably connected between the two sides of the inner wall of the movable frame 2 through a rotating shaft. The rotating block 13 is fixedly set on the outer wall of the rotating rod. The auxiliary gear 18 is fixedly set on the outer wall of the rotating rod and meshes with the main gear 19. The main gear 19 is driven to rotate through the coupling. The main gear 19 meshes with the auxiliary gear 18, thereby driving the rotating rod and the rotating block 13 to rotate. The dosing box 11 is set on the rotating block 13. When the rotating block 13 rotates, it will drive the dosing box 11 to rotate, which can achieve uniform diffusion and improve the reaction effect.

[0033] The limiting block 15 is fixedly installed on the bottom side of the feeding box 11. The limiting groove 14 is opened on one side of the rotating block 13 for the limiting block 15 to be locked. The locking screw 16 is threadedly connected to the inside of one side of the rotating block 13. The screw hole 17 is opened on one side of the limiting block 15 for the locking screw 16 to be threaded and locked. The rotating block 13 has a limiting groove 14, and the bottom side of the feeding box 11 is fixed with a limiting block 15 that engages with the limiting groove 14. When the limiting block 15 is slidably engaged with the rotating block 13, the locking screw 16 is rotated and threadedly locked with the screw hole 17 on the limiting block 15, thereby locking the feeding box 11 onto the rotating block 13 to facilitate rotation.

[0034] This application can be used in the field of photovoltaic wastewater treatment, or in other fields applicable to this application. Example

[0035] refer to Figure 1 and Figure 2 An improvement based on Example 1: a PAM dosing device for photovoltaic wastewater flocculation tanks, which is applied to the field of photovoltaic wastewater.

[0036] The movable mechanism, mounted on the flocculation tank body 1, drives the moving frame 2 to move. The movable mechanism includes a threaded block 3, a moving block 4, a first motor 5, a lead screw 6, a fixed plate 7, a limiting rod 8, a pulley 9, and a sliding groove 10. The threaded block 3 and the moving block 4 are fixedly mounted on opposite sides of the moving frame 2. The first motor 5 is fixedly mounted on one side of the flocculation tank body 1. The output end of the first motor 5 is fixed to one end of the lead screw 6 via a coupling. The threaded block 3 is threaded onto the outer wall of the lead screw 6, driving the lead screw 6 to rotate via the coupling. Because the threaded block 3 is threaded onto the outer wall of the lead screw 6, the rotation of the lead screw 6 is converted into linear movement of the threaded block 3, thereby controlling the moving speed and direction of the moving frame 2. This achieves precise control of the PAM dispensing position, further expanding the dispensing range and improving the uniformity of dispensing.

[0037] Two fixed plates 7 are fixedly installed on one side of the flocculation tank body 1, and the limiting rods 8 are fixedly installed on both sides of the two fixed plates 7. The moving block 4 has a sliding hole that is slidably connected to the outer wall of the limiting rod 8. Four pulleys 9 are fixedly installed on the bottom side of the moving frame 2. Two sliding grooves 10 are opened on the top side of the flocculation tank body 1 for the pulleys 9 to slide and limit. The moving block 4 is slidably connected to the limiting rod 8 through the internal sliding hole, which plays a guiding and stabilizing role. The pulleys 9 cooperate with the sliding grooves 10 to further restrict the movement direction of the moving frame 2, ensuring that it can only move along a specific path and improving stability.
