Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane production technology, specifically to a coagulant addition mechanism for reverse osmosis membrane production. Background Technology

[0002] A reverse osmosis membrane is an artificial semi-permeable membrane made by simulating a biological semi-permeable membrane. It uses the principle of membrane separation to separate the solvent and solute under a pressure higher than that of the solution. Only water molecules can pass through the membrane, while other substances such as dissolved salts, colloids, microorganisms, and organic matter are retained, thereby purifying the water.

[0003] In the process of reverse osmosis membrane production, coagulants need to be added through an additive mechanism to improve the feed water quality and protect the reverse osmosis membrane. However, the existing additive mechanism controls the addition of coagulants by starting and stopping the motor. Due to the gap in the screw, some coagulants will still fall out from the gap at the discharge pipe after the motor stops running, which can easily lead to the inability to control the discharge in a timely manner. Utility Model Content

[0004] The purpose of this invention is to provide a coagulant addition mechanism for reverse osmosis membrane production, in order to solve the problem mentioned in the background art where the addition mechanism controls the addition of coagulant by starting and stopping the motor. Due to the gap in the screw rod, some coagulant will still fall out from the gap at the discharge pipe after the motor stops running, which can easily cause the discharge to be uncontrollable in a timely manner.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coagulant addition mechanism for reverse osmosis membrane production, comprising: The main body includes a base, on which a housing and a drive motor are fixedly connected. A screw rod is movably connected to the inner surface of the housing, and a storage bin and a discharge pipe are fixedly connected to the outer surface of the housing.

A screw is installed on the inner surface of the side plate. A nut is threadedly connected to the surface of the screw. An operating rod is installed on the surface of the nut. A baffle is installed on the surface of the screw.

[0006] Preferably, the rotating rod is rotatably connected to the surface of the rotating hole, and two sets of rotating holes, connecting rods and fixing blocks are provided.

[0008] Preferably, the surface of the operating lever is in the shape of a long rod, and two sets of operating levers are provided, with the two sets of operating levers fixedly connected to both sides of the nut.

[0009] Preferably, the surface of the storage bin is provided with an expansion mechanism, the expansion mechanism including a feeding hopper, the feeding hopper being abutted against the surface of the storage bin, a connecting bin being fixedly connected to the outer surface of the storage bin, a connecting plate being fixedly connected to the outer surface of the feeding hopper, a spring and a protrusion being movably connected to the inner surface of the connecting bin, a through hole being opened on the surface of the connecting bin, and an insertion hole being opened on the surface of the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By installing a baffle plate on the inner surface of the discharge pipe and fixing its position by tightening the nut, the baffle plate can block the coagulant when the operator stops adding and turns off the drive motor, thus preventing some coagulant from falling out of the discharge pipe.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: A coagulant addition mechanism for reverse osmosis membrane production includes: The main body includes a base 1, with a housing 11 and a drive motor 12 fixedly connected to the surface of the base 1. A screw rod 13 is movably connected to the inner surface of the housing 11, and a storage bin 14 and a discharge pipe 15 are fixedly connected to the outer surface of the housing 11. When in use, the addition mechanism is installed at the water supply position in the reverse osmosis membrane production via the base 1. The coagulant is added into the housing 11 through the storage bin 14. The start of the drive motor 12 drives the screw rod 13 to rotate and transport the coagulant to the discharge pipe 15, and the coagulant is discharged from the discharge pipe 15 to achieve the addition function. The control mechanism includes a partition 2, which is movably connected to the inner surface of the discharge pipe 15. A rotating rod 21 is fixedly connected to the surface of the partition 2. A rotating hole 22 is opened on the surface of the discharge pipe 15. A connecting rod 23 is fixedly connected to the surface of the rotating rod 21. A side plate 24 is fixedly connected to the surface of the connecting rod 23. A fixing block 25 is fixedly connected to the outer surface of the discharge pipe 15. A screw 26 is installed on the inner surface of the side plate 24. A nut 27 is threadedly connected to the surface of the screw 26. An operating rod 28 is installed on the surface of the nut 27. A baffle 29 is installed on the surface of the screw 26. The partition 2 can block the coagulant discharged from the discharge pipe 15, thereby achieving the opening and closing effect, allowing the staff to control the coagulant in a timely manner.

[0018] Furthermore, the rotating rod 21 is rotatably connected to the surface of the rotating hole 22. Two sets of rotating holes 22, connecting rods 23, and fixing blocks 25 are provided. The two sets of rotating holes 22 are opened on both sides of the discharge pipe 15. The two sets of connecting rods 23 are installed at both ends of the rotating rod 21. There are two connecting rods 23 in each set. The two sets of fixing blocks 25 are installed on both sides of the discharge pipe 15. With the connection of the rotating rod 21 and the rotating hole 22, the partition plate 2 can rotate around the rotating rod 21. Each set of connecting rods 23 is set at both ends of the side plate 24. One end of the connecting rod 23 is fixed to the surface of the rotating rod 21 and the other end is fixed to the surface of the side plate 24, thereby connecting the side plate 24 and the rotating rod 21. The side plate 24 and the screw 26 can be installed through the fixing blocks 25.

[0019] Furthermore, the surface of the side plate 24 is arc-shaped, and the side plate 24 is abutted against the surface of the fixing block 25. One end of the screw 26 is fixedly connected to the surface of the fixing block 25, and the other end of the screw 26 is fixedly connected to the surface of the baffle 29. The nut 27 is abutted against the surface of the side plate 24. The surface of the side plate 24 is a quarter-circle arc with the rotating rod 21 as the center. The screw 26 passes through and is connected to the surface of the side plate 24. With the connection of the screw 26 and the nut 27, the side plate 24 can be limited and fixed to the surface of the fixing block 25. The rotating rod 21 can be fixed through the connection of the connecting rod 23, thereby limiting the state of the partition 2. The baffle 29 can limit the nut 27 and keep it moving on the surface of the screw 26 to prevent it from loosening and falling off.

[0020] Furthermore, the surface of the operating lever 28 is long and rod-shaped. There are two sets of operating levers 28, which are fixedly connected to both sides of the nut 27. Under the action of the operating lever 28, it is easier for the operator to rotate the nut 27 without the need for other tools, and it also provides convenience for controlling the partition 2.

[0021] Furthermore, the surface of the storage silo 14 is provided with an expansion mechanism, which includes a feeding hopper 3. The feeding hopper 3 is abutted and connected to the surface of the storage silo 14. A connecting chamber 31 is fixedly connected to the outer surface of the storage silo 14. A connecting plate 32 is fixedly connected to the outer surface of the feeding hopper 3. A spring 33 and a protrusion 34 are movably connected to the inner surface of the connecting chamber 31. A through hole 35 is opened on the surface of the connecting chamber 31. An insertion hole 36 is opened on the surface of the connecting plate 32. The surface of the feeding hopper 3 is in the shape of an inverted frustum. Under the action of the feeding hopper 3, the range in which the operator pours coagulant into the storage silo 14 can be expanded.

[0022] Furthermore, two sets of connecting bins 31 and connecting plates 32 are provided. The two sets of connecting bins 31 are installed on both sides of the storage bin 14, and the two sets of connecting plates 32 are installed on both sides of the feed hopper 3. One end of the spring 33 is fixedly connected to the inner surface of the connecting bin 31, and the other end of the spring 33 is fixedly connected to the surface of the protrusion 34. With the connection of the two sets of connecting bins 31 and connecting plates 32, the storage bin 14 and the feed hopper 3 can be connected. When the connecting plate 32 is installed, one end is fixed to the outside of the feed hopper 3, and the other end is tightly attached to the outer surface of the connecting bin 31. Under the action of the spring 33, a supporting force can be applied to the surface of the protrusion 34 and make it always tend to move towards the through hole 35.

[0023] Furthermore, one side of the protrusion 34 abuts against the inner surface of the connecting chamber 31, and the other side of the protrusion 34 inserts into the surfaces of the through hole 35 and the insertion hole 36. The diameter of the through hole 35 and the diameter of the insertion hole 36 are the same. The side of the protrusion 34 that abuts against the inner surface of the connecting chamber 31 is plate-shaped, while the side that inserts into the through hole 35 and the insertion hole 36 is cylindrical. The bottom diameter of the cylindrical side is the same as the diameter of the through hole 35 and the insertion hole 36. With the connection of the protrusion 34 and the through hole 35 and the insertion hole 36 on both sides, the connecting plate 32 can be limited and fixed on the surface of the connecting chamber 31 to achieve the installation effect of the feeding hopper 3.

[0024] Working principle: Before stopping the addition of coagulant, first rotate the operating rod 28 to drive the nut 27 to move towards the baffle 29 through the thread and cancel the engagement with the side plate 24. Then, stop the drive motor 12 and move the side plate 24 to make the partition 2 rotate around the rotating rod 21. The rotating rod 21 rotates in the rotating hole 22. At this time, the screw 26 is placed from one end of the inner surface of the side plate 24 to the other end. The partition 2 blocks and intercepts the coagulant at the discharge pipe 15. Then, rotate the operating rod 28 again to make the nut 27 tighten again and abut against the surface of the side plate 24 to complete the limiting and fixing of the partition 2. Thus, the addition of coagulant can be controlled in a timely manner.

[0025] Before adding coagulant into the feeding mechanism, the feeding hopper 3 is installed and abutted against the surface of the storage bin 14. The connecting plates 32 on both sides of the feeding hopper 3 are aligned with the connecting bins 31 on both sides of the storage bin 14. At the same time, the cylindrical side of the protrusion 34 is pressed down so that it moves into the connecting bin 31 through the through hole 35 and slides on the inner surface of the connecting bin 31. The spring 33 is in a compressed state. When the connecting plate 32 is attached to the outer surface of the connecting bin 31 and the holes of the through hole 35 and the insertion hole 36 are aligned, the protrusion 34 is inserted and locked into the insertion hole 36 under the supporting force applied by the spring 33, so as to complete the installation and fixation of the feeding hopper 3. Then the coagulant can be added into the storage bin 14 of the feeding mechanism through the feeding hopper 3.
