Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment for paper product manufacturing, and specifically relates to a wastewater treatment device for paper product manufacturing. Background Art

[0002] A large amount of wastewater is generated during the production of paper products. If it is directly discharged without treatment, it will damage water resources and cause great changes in the surrounding ecological environment. Therefore, a wastewater treatment machine is needed for treatment.

[0003] Currently, the wastewater treatment for paper product manufacturing is all in the form of filtration. A filter plate is placed inside the device to filter the wastewater. However, with long-term use, the impurities that the filter plate can filter reach the limit, which will cause the filter plate to become blocked. The staff needs to replace the filter plate. But during the replacement process, the entire device can only be stopped, affecting the work efficiency. For this reason, we propose a wastewater treatment device for paper product manufacturing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wastewater treatment device for paper product manufacturing to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A wastewater treatment device for paper product manufacturing, including a treatment tank. A connecting pipe is fixedly connected and communicated with the top of the treatment tank. A drain pipe is fixedly connected and communicated with the bottom of the treatment tank. A filter plate is inserted into the interior of the treatment tank. A switching component for assisting in replacing the filter plate is arranged inside the treatment tank. The switching component includes:

[0006] A partition plate, the bottom of the partition plate is fixed on the inner wall of the treatment tank. A turntable is rotatably installed on the top of the partition plate. The top of the turntable is rotatably connected with the treatment tank. Two through holes are opened on the turntable;

[0007] Rotating rod, the rotating rod penetrates through the top of the partition plate and is rotatably connected to the partition plate. The top of the rotating rod is fixed to the bottom of the turntable. A spiral chute is provided on the surface of the rotating rod. A sliding rod is inserted into the inside of the spiral chute. A chute is provided on the surface of the processing box. The sliding rod passes through the chute and is slidably connected to the chute. A connecting spring is fixed to the top of the sliding rod. One end of the connecting spring away from the sliding rod is fixed to the inside of the chute. When a set of through holes on the turntable coincides with a set of connecting pipes, the connecting pipes are no longer blocked, and the wastewater can flow through the connecting pipes into the processing box and be filtered by the filter plate, and then discharged through the drain pipe. When the sliding rod is pulled downward, the sliding rod can slide downward in the spiral chute on the surface of the rotating rod, causing the rotating rod to rotate. The rotating rod can drive the turntable to rotate, so that a set of through holes on the turntable no longer coincides with a set of connecting pipes, and another set of through holes coincides with another set of connecting pipes, thus realizing the switching function. Just replace the filter plate on the corresponding side without stopping the overall operation of the equipment, which is convenient to use.

[0008] Preferably, a prompting component is provided inside and on the surface of the processing box. The prompting component includes a prompting pointer. The prompting pointer penetrates through the surface of the processing box and is rotatably connected to the processing box. The prompting pointer is fixed to the disc.

[0009] Preferably, a support rod is hinged to one side of the disc away from the prompting pointer. One end of the support rod away from the disc is hinged to the top of the counterweight. The counterweight is slidably installed on the inner wall of the processing box. When the sliding rod is in the top position, it can push the counterweight upward. The counterweight pushes the disc and the prompting pointer to rotate through the support rod, so that the prompting pointer points to the right. When the sliding rod is in the bottom position, the counterweight is no longer pushed. The counterweight pulls the support rod under its own gravity, causing the disc and the prompting pointer to rotate in the opposite direction, and the prompting pointer points to the left. Thus, it can effectively prompt the staff which side of the filter plate can be disassembled, and has strong practicability.

[0010] Preferably, a locking and limiting component is provided on the sliding rod and inside the processing box. The locking and limiting component includes a pressing rod. A U-shaped clamping rod is fixed to one side of the pressing rod close to the sliding rod. The U-shaped clamping rod penetrates through the sliding rod and is slidably connected to the sliding rod. A return spring is fixed to the inner wall of the sliding rod. One end of the return spring away from the sliding rod is fixed to the surface of the U-shaped clamping rod.

[0011] Preferably, a card slot is provided on the inner side of the slide groove on the surface of the processing box, the partition is penetrated by the resistance block and is slidably connected with the resistance block, a fixing spring is fixed on the inner wall of the partition, the end of the fixing spring away from the partition is fixed to the surface of the resistance block, the side of the resistance block away from the partition is hinged with a connecting rod, the end of the connecting rod away from the resistance block is hinged to a limiting plate, the limiting plate is slidably installed on the inner wall of the processing box, and limiting slots are provided on the top and bottom of the filter plate. When the staff holds the sliding rod, they can pinch the pressure rod to make the pressure rod fit with the sliding rod, and the pressure rod can drive the U-shaped card rod to retract into the sliding rod, so that the U-shaped card rod is no longer stuck in the card slot, so that the limit on the sliding rod is released, and the sliding rod can be pushed up and down to move.

[0012] Preferably, the resistance block, fixing spring, connecting rod and limit plate are all provided with two groups, and when the sliding bar is in the top position, the sliding bar can resist on the top resistance block, pushing the top resistance block to move right, and the resistance block pushes the limit plate downward through the connecting rod, so that the limit plate is inserted into the limit groove at the top of the right filter plate, ensuring the stability of the right filter plate when in use. When the sliding bar is in the bottom position, the sliding bar can resist on the bottom resistance block, pushing the bottom resistance block to move left, and the resistance block pushes the limit plate upward through the connecting rod, so that the limit plate is inserted into the limit groove at the bottom of the left filter plate, ensuring the stability of the left filter plate when in use, and when the sliding bar is at the top, under the action of the fixing spring, the limit plate releases the limit on the left filter plate, which is convenient for the staff to replace it, and when the sliding bar is at the bottom, the limit plate releases the limit on the right filter plate.

[0013] Compared with the prior art, the utility model provides a wastewater treatment equipment for paper product manufacturing, which has the following beneficial effects:

[0014] 1. For the wastewater treatment equipment for paper product manufacturing, when it is necessary to replace the filter plate on the left or right side, one only needs to pinch the slide bar to control the U-shaped clamping rod to release the limit on the slide bar, and then pull the slide bar up or down to control the rotation of the turntable, so that one set of through holes on the turntable and one set of connecting pipes no longer overlap, while the other set of through holes overlaps with the other set of connecting pipes, thereby realizing the switching effect, and the filter plate on the corresponding side can be replaced without stopping the overall operation of the equipment, which is convenient to use.

[0015] 2. For the wastewater treatment equipment for paper product manufacturing, when the slide bar is in the top position, the counterweight block can be pushed upward, and the counterweight block pushes the disc and the prompt pointer to rotate through the support rod, so that the prompt pointer points to the right. When the slide bar is in the bottom position, the counterweight block is no longer resisted, and the counterweight block pulls the support rod under the action of its own gravity, so that the disc and the prompt pointer rotate in the opposite direction, and the prompt pointer points to the left, thereby effectively prompting the staff which side of the filter plate can be disassembled, and it is more practical.

[0025] like Figures 1 - 8 As shown, the utility model provides a technical solution: a wastewater treatment device for paper product manufacturing, including a treatment box 1, the top of the treatment box 1 is fixed and connected with a connecting pipe 2, the bottom of the treatment box 1 is fixed and connected with a drainage pipe 5, a filter plate 6 is inserted into the interior of the treatment box 1, and a switching component 3 for assisting in replacing the filter plate 6 is arranged inside the treatment box 1. The switching component 3 includes: a partition 31, a turntable 32, a through hole 33, a rotating rod 34, a spiral slide 35, a slide rod 36, a slide 37, and a connecting spring 38.

[0026] The bottom of the partition plate 31 is fixed on the inner wall of the treatment tank 1. The top of the partition plate 31 is rotatably installed with a turntable 32. The top of the turntable 32 is rotatably connected to the treatment tank 1. Two through holes 33 are formed in the turntable 32. A rotating rod 34 passes through the top of the partition plate 31 and is rotatably connected to the partition plate 31. The top of the rotating rod 34 is fixed to the bottom of the turntable 32. A spiral chute 35 is formed on the surface of the rotating rod 34. A sliding rod 36 is inserted into the inner side of the spiral chute 35. A chute 37 is formed on the surface of the treatment tank 1. The sliding rod 36 passes through the chute 37 and is slidably connected to the chute 37. A connecting spring 38 is fixed to the top of the sliding rod 36. One end of the connecting spring 38 away from the sliding rod 36 is fixed to the inner side of the chute 37. When a set of through holes 33 on the turntable 32 coincides with a set of connecting pipes 2, the connecting pipes 2 are no longer blocked, and the wastewater can flow into the treatment tank 1 through the connecting pipes 2, be filtered by the filter plate 6, and then be discharged through the drain pipe 5. When the sliding rod 36 is pulled downward, the sliding rod 36 can slide downward in the spiral chute 35 on the surface of the rotating rod 34, causing the rotating rod 34 to rotate. The rotating rod 34 can drive the turntable 32 to rotate, so that a set of through holes 33 on the turntable 32 no longer coincides with a set of connecting pipes 2, and another set of through holes 33 coincides with another set of connecting pipes 2, thus realizing the switching function. The filter plate 6 on the corresponding side can be replaced, and there is no need to stop the overall operation of the equipment, which is convenient to use.

[0027] A prompting component 4 is arranged inside and on the surface of the treatment tank 1. The prompting component 4 includes a prompting pointer 41. The prompting pointer 41 passes through the surface of the treatment tank 1 and is rotatably connected to the treatment tank 1. The prompting pointer 41 is fixed to a disc 42. One side of the disc 42 away from the prompting pointer 41 is hinged with a support rod 43. One end of the support rod 43 away from the disc 42 is hinged to the top of a counterweight 44. The counterweight 44 is slidably installed on the inner wall of the treatment tank 1. When the sliding rod 36 is in the top position, it can push the counterweight 44 upward. The counterweight 44 pushes the disc 42 and the prompting pointer 41 to rotate through the support rod 43, so that the prompting pointer 41 points to the right. When the sliding rod 36 is in the bottom position, the counterweight 44 is no longer pushed. The counterweight 44 pulls the support rod 43 under the action of its own gravity, causing the disc 42 and the prompting pointer 41 to rotate in the opposite direction, and the prompting pointer 41 points to the left. Thus, it can effectively prompt the staff which side of the filter plate 6 can be disassembled, and has strong practicability.

[0028] A locking limit assembly 7 is provided on the slide bar 36 and inside the processing box 1. The locking limit assembly 7 includes a pressure rod 71. A U-shaped clamping rod 72 is fixed to the side of the pressure rod 71 close to the slide bar 36. The U-shaped clamping rod 72 penetrates the slide bar 36 and is slidably connected to the slide bar 36. A return spring 73 is fixed to the inner wall of the slide bar 36. The end of the return spring 73 away from the slide bar 36 is fixed to the surface of the U-shaped clamping rod 72. A clamping groove 74 is provided on the inner side of the slide groove 37 on the surface of the processing box 1. The partition 31 is penetrated by the resistance block 75 and is slidably connected to the resistance block 75. A fixing spring 76 is fixed to the inner wall of the partition 31. The fixing spring 76 is away from the partition 3 One end of 1 is fixed to the surface of the resistance block 75, and the side of the resistance block 75 away from the partition 31 is hinged with a connecting rod 77, and the end of the connecting rod 77 away from the resistance block 75 is hinged with a limiting plate 78, and the limiting plate 78 is slidably installed on the inner wall of the processing box 1. The top and bottom of the filter plate 6 are provided with limiting grooves 79. When the staff holds the slide bar 36, they can pinch the pressure rod 71 to make the pressure rod 71 fit with the slide bar 36. The pressure rod 71 can drive the U-shaped clamping rod 72 to retract into the slide bar 36, so that the U-shaped clamping rod 72 is no longer stuck in the clamping groove 74, so that the limit of the slide bar 36 is released, and the slide bar 36 can be pushed up and down to move.

[0029] The retaining plate 78 is provided with two groups, and when the slide bar 36 is in the top position, the slide bar 36 can be abutted against the top retaining block 75, pushing the top retaining block 75 to move to the right, and the retaining block 75 pushes the retaining plate 78 to move downward through the connecting rod 77, so that the retaining plate 78 is inserted into the retaining groove 79 at the top of the right filter plate 6, ensuring the stability of the right filter plate 6 when in use. When the slide bar 36 is in the bottom position, the slide bar 36 can be abutted against the bottom retaining groove 79, so as to ensure the stability of the right filter plate 6 when in use. The contact block 75 pushes the bottom resistance block 75 to move to the left, and the resistance block 75 pushes the limit plate 78 to move upward through the connecting rod 77, so that the limit plate 78 is inserted into the limit groove 79 at the bottom of the left filter plate 6, thereby ensuring the stability of the left filter plate 6 during use. When the slide bar 36 is at the top, under the action of the fixing spring 76, the limit plate 78 releases the limit on the left filter plate 6, making it convenient for the staff to replace it. When the slide bar 36 is at the bottom, the limit plate 78 releases the limit on the right filter plate 6.

[0030] Based on the above embodiment, the connecting pipe 2 on the top of the processing box 1 is first connected to the paper product production equipment through flanges and bolts, and then the drainage pipe 5 at the bottom is connected to the pool.

[0031] The wastewater generated by the paper product production equipment enters the treatment tank 1 through the connecting pipe 2 on the right side, and then is filtered by the filter plate 6 on the right side and discharged through the drain pipe 5. When the filter plate 6 on the right side needs to be replaced after long-term use, just hold the sliding rod 36 and squeeze the pressing rod 71 so that the pressing rod 71 fits with the sliding rod 36. The pressing rod 71 can drive the U-shaped clamping rod 72 to retract into the sliding rod 36, so that the U-shaped clamping rod 72 no longer clamps in the clamping groove 74, realizing the release of the limit on the sliding rod 36. Pull the sliding rod 36 downward, and the sliding rod 36 can slide downward in the spiral chute 35 on the surface of the rotating rod 34, causing the rotating rod 34 to rotate. The rotating rod 34 can drive the turntable 32 to rotate, so that a set of through holes 33 on the turntable 32 no longer coincide with a set of connecting pipes 2, while another set of through holes 33 coincides with another set of connecting pipes 2, thus realizing the switching function. At this time, the sliding rod 36 is in the bottom position, and the sliding rod 36 can abut against the bottom abutting block 75, pushing the bottom abutting block 75 to move leftward. The abutting block 75 pushes the limiting plate 78 upward through the connecting rod 77, so that the limiting plate 78 is inserted into the limiting groove 79 at the bottom of the left filter plate 6 to ensure the stability of the left filter plate 6 during use. And the abutting block 75 on the right side is no longer abutted, so that the limit on the right filter plate 6 can be released, and the right filter plate 6 can be pulled out and replaced.

[0032] At the same time, the counterweight 44 is no longer abutted, and the counterweight 44 pulls the support rod 43 under its own gravity, causing the disc 42 and the indicating pointer 41 to rotate in the opposite direction. The indicating pointer 41 points to the left, which is convenient for the staff to identify which side of the filter plate 6 is working.

[0033] The above text generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements without departing from the spirit of the present invention are within the protection scope of the present invention.
