Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a purifier for treating papermaking wastewater. Background Art

[0002] Papermaking wastewater refers to wastewater generated during the papermaking process that contains pollutants such as suspended matter, organic matter, and chemicals. The papermaking industry is a typical industry that consumes a lot of water, and its wastewater discharge causes great pollution to the environment. These wastewaters usually contain high concentrations of organic matter, suspended matter, high pH, and other chemical substances.

[0003] A search revealed patent document CN119191446A, which discloses a wastewater treatment and purification device comprising a treatment tank and a stirring rod rotatably disposed within the treatment tank. The stirring rod is provided with a stirring support rod, and the treatment tank is provided with a drive element for driving the stirring rod. The treatment tank is also provided with a water inlet pipe and a drain pipe, and the water inlet pipe is provided with a water inlet valve. This patent application utilizes a driving element to drive a grinding block for grinding, improving user convenience.

[0004] The above patent also has the following defects: for example, there is a risk of blockage in the feeding trough. When the powder in the application passes through the feeding trough, it is easy to cause blockage due to moisture agglomeration or uneven particles. Especially when the wastewater flow rate is small, the flushing effect of the water inlet pipe is insufficient, which causes the powder to be easily retained and the powder accumulates to block the feeding trough, thereby affecting continuous addition.

[0005] In view of this, a purifier for treating papermaking wastewater is proposed to solve the above problems. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the present invention provides a purifier for treating papermaking wastewater, which has the advantages of high automation and good anti-clogging effect, and solves the problem of clogging caused by moisture agglomeration or uneven particles when powder passes through the feeding trough.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a purifier for treating papermaking wastewater, comprising a purification treatment tank, wherein the purification treatment tank is provided with a first treatment mechanism, a driving mechanism and a second treatment mechanism;

[0008] The second processing mechanism is composed of a grinding structure, a reciprocating structure and a piston assembly;

[0009] The reciprocating structure includes a limiting component, an abutting component, a knocking component and a driving plate;

[0010] The abutment assembly includes an elastic guide rod provided on the limiting assembly and a ball rotatably mounted on an end of the elastic guide rod away from the limiting assembly;

[0011] The knocking assembly includes a swing shaft rotatably arranged on the limit assembly, a knocking block is fixed to the bottom end of the swing shaft, a shaft is fixed to the top end of the swing shaft, and a bearing is installed on the other end of the shaft to carry a rolling wheel that rolls with the driving plate, and a linear groove and a wave groove are provided inside the driving plate to match the rolling wheel;

[0012] The piston assembly includes a piston cylinder arranged outside the grinding structure, a piston block is slidably arranged inside the piston cylinder, a connecting rod extending to the outside of the piston cylinder and connected to the driving mechanism is fixed on the upper surface of the piston block, and a delivery pipe is arranged between the side wall of the piston cylinder and the grinding structure.

[0013] This application adopts the above-mentioned technical solution, and regularly knocks the grinding cylinder through the reciprocating knocking block, which effectively prevents the powder from being blocked during the grinding and conveying process, ensures the continuity of grinding and conveying, avoids equipment shutdown due to blockage, and improves the stability and reliability of the equipment.

[0014] Furthermore, the processing mechanism includes a transmission sleeve with a bearing installed on the top side of the purification treatment tank. The transmission sleeve is a hollow shaft, and the bottom end of the transmission sleeve extends into the interior of the purification treatment tank. The internal spline of the transmission sleeve is connected to a stirring rod, and the top end of the stirring rod passes through the interior of the transmission sleeve. A feed port is provided on the outer wall of the purification treatment tank.

[0015] The beneficial effects of adopting the above-mentioned further scheme are: through the hollow shaft design of the transmission sleeve, space is provided for the lifting and lowering movement of the stirring rod, and other auxiliary components can be accommodated at the same time, making the equipment structure more compact. At the same time, the spline connection realizes the synchronous rotation of the stirring rod and the transmission sleeve, and allows the stirring rod to be freely lifted and lowered along the axial direction, thereby enhancing the flexibility of stirring.

[0016] Furthermore, the driving mechanism includes a driving motor and a support shaft arranged on the top side of the purification tank, an inclined disk is fixed to the top end of the support shaft, the driving motor is a dual-shaft motor, and transmission gears are fixed on both output shafts of the driving motor. The outside of the transmission gear at the bottom is engaged with a first driven gear fixed to the outer surface of the transmission sleeve, and the outside of the transmission gear at the top is engaged with a second driven gear fixed to the support shaft.

[0017] The beneficial effects of adopting the above-mentioned further scheme are as follows: the driving motor is a dual-axis motor, which can simultaneously drive the bottom and top sets of transmission gears, realizing the coordinated work of multiple mechanisms driven by a single motor, reducing the number of motors, and reducing energy consumption and equipment costs. The bottom transmission gear drives the transmission sleeve to rotate through the first driven gear, thereby driving the stirring rod to rotate; the top transmission gear drives the support shaft to rotate through the second driven gear, realizing power diversion and improving transmission efficiency.

[0018] Furthermore, the driving mechanism also includes a connecting frame arranged at the top end of the stirring rod, the top end of the stirring rod is rotatably connected to one end of the connecting frame, the outer surface of the connecting frame is fixed with an abutting roller that abuts against the upper surface of the inclined disk, and the top side of the purification tank is fixed with a frame supporting the driving motor, and the support shaft bearing is installed on the frame.

[0019] The beneficial effect of adopting the above further scheme is: through the cooperation between the inclined disk at the top of the support shaft and the abutment roller on the connecting frame, the rotational motion of the support shaft is converted into the lifting motion of the stirring rod. The lifting and lowering of the stirring rod can enhance the mixing effect of wastewater and purifier, prevent sedimentation, and improve treatment efficiency.

[0020] Furthermore, the grinding structure includes a grinding cylinder arranged on the top side of the purification tank, a grinding head is arranged inside the grinding cylinder, a connecting shaft is fixed on the top side of the grinding head, a discharge pipe fixed to the inside of the purification tank is welded on the bottom side of the grinding cylinder, the discharge pipe extends into the interior of the purification tank, and the top outer surface of the connecting shaft is rotatably connected to the other end of the connecting frame.

[0021] The beneficial effect of adopting the above further solution is that the reciprocating motion of the grinding head can effectively prevent the powder from compacting in the grinding barrel, and combined with the periodic knocking of the knocking component, the risk of clogging is further reduced.

[0022] Furthermore, a feeding pipe is fixedly connected to the outer wall of the grinding cylinder, and coaxial channels are provided inside the connecting shaft and the grinding head. A guide groove is provided inside the connecting shaft to cooperate with the rolling of the ball, and the guide groove is spirally arranged around the outer surface of the connecting shaft.

[0023] The beneficial effect of adopting the above-mentioned further scheme is: the grinding head is rotatably connected to the connecting frame through the connecting shaft, and the balls roll in the guide groove, thereby realizing the decoupling of the lifting and rotating motion of the grinding head. The reciprocating motion of the connecting frame drives the grinding head to rise and fall, and the grinding head can rotate freely during the lifting process, thereby enhancing the uniformity of grinding and the fineness of powder.

[0024] Furthermore, the limiting assembly includes a support seat fixed to the top side of the grinding cylinder, a limiting rod is fixed inside the support seat, the elastic guide rod is installed on the left end of the limiting rod by a bolt, and the swing shaft is rotatably installed on the outer surface of the limiting rod through a circular axis.

[0025] The beneficial effects of adopting the above-mentioned further scheme are: the support seat is fixed to the top side of the grinding cylinder, providing rigid support for the limit rod, ensuring the installation position accuracy of the elastic guide rod and the swing shaft, and the limit rod is rigidly connected to the grinding cylinder through the support seat to form a stable reference frame, reducing the component offset caused by vibration during the grinding process and improving the operation stability of the equipment.

[0026] Furthermore, the shape of the knocking block is adapted to the grinding cylinder, and a buffer pad is fixed on the inner side of the knocking block. A connecting frame rotatably connected to the connecting shaft is fixed on the outer wall of the driving plate, and the top of the wave groove is connected to the bottom of the straight groove.

[0027] The beneficial effect of adopting the above-mentioned further scheme is: by closely fitting the shape of the knocking block with the curvature of the outer wall of the grinding cylinder, the knocking energy is ensured to be concentrated on the areas of the grinding cylinder that are prone to clogging, such as the interface of the feed pipe, thereby improving the anti-clogging effect. The buffer pad can absorb the impact force of the knocking, avoiding metal fatigue of the grinding cylinder due to repeated knocking, extending the life of the equipment, and reducing noise.

[0028] Furthermore, a check valve is provided inside the piston cylinder and the piston block, one end of the delivery pipe is connected to the end of the check valve through a flange, and the other end of the delivery pipe is rotatably connected to the top end of the connecting shaft.

[0029] The beneficial effect of adopting the above further solution is: by matching the rapid opening and closing characteristics of the check valve with the reciprocating motion of the piston assembly, pulsed spraying of the powder is achieved, thereby improving the mixing uniformity of the powder and wastewater.

[0030] Furthermore, the top end of the connecting rod extends to the outside of the piston cylinder, and the top end of the connecting rod is fixed to the lower surface of the connecting frame by bolts, and a buffer spring surrounding the outside of the connecting rod is fixed between the top side of the piston cylinder and the lower surface of the connecting frame.

[0031] The beneficial effects of adopting the above-mentioned further scheme are: the buffer spring is compressed when the connecting frame moves downward, absorbing the impact energy, reducing the rigid collision between the piston block and the piston cylinder end cover, and reducing noise. At the same time, the elastic force of the spring can compensate for the slight deviation in the movement of the connecting frame, making the reciprocating motion of the piston block smoother and reducing the pressure fluctuation during the powder conveying process.

[0032] Compared with the prior art, the present invention provides a purifier for treating papermaking wastewater, which has the following beneficial effects:

[0033] This purifier for treating papermaking wastewater uses a wave groove to force the rolling wheel to move laterally through the linear motion of the driving plate to generate a lever torque effect. The torque is transmitted to the swing shaft, causing the knocking block to hit the grinding cylinder with angular acceleration. The instantaneous impact force of the knocking block destroys the adhesion of powder fibers, effectively preventing powder from being blocked during the grinding and conveying process, ensuring the continuity of grinding and conveying, avoiding equipment shutdown due to blockage, and improving the stability and reliability of the equipment.

[0034] 2. The purifier for treating papermaking wastewater has a connecting shaft linked to the drive mechanism through a connecting frame, directly utilizing the power of the drive motor, reducing the need for additional power sources and lowering energy consumption. The lifting movement of the grinding head is driven by an inclined disk, sharing the same power source as the lifting movement of the stirring rod, thereby improving power utilization efficiency. In addition, the ground powder directly enters the purification treatment tank through a discharge pipe and is quickly mixed with the wastewater, shortening the dissolution time of the purifier and improving the treatment efficiency. The increased fineness of the powder increases its contact area with the wastewater, accelerating the purification reaction and improving the wastewater treatment effect.

DETAILED DESCRIPTION

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] See also Figures 1 to 9 In this embodiment, a purifier for treating papermaking wastewater includes a purification tank 1, which is equipped with a treatment mechanism 1 2, a drive mechanism 3, and a treatment mechanism 2 5. Treatment mechanism 2 5 comprises a grinding structure 6, a reciprocating structure 7, and a piston assembly 8. Treatment mechanism 1 2 includes a transmission sleeve 201 mounted on the top side of the purification tank 1 by a bearing. Transmission sleeve 201 is a hollow shaft, and the bottom end of transmission sleeve 201 extends into the interior of the purification tank 1. A stirring rod 202 is splined internally to transmission sleeve 201, and the top end of stirring rod 202 extends through the interior of transmission sleeve 201. A feed port 4 is provided on the outer wall of the purification tank 1. The hollow shaft design of the transmission sleeve 201 provides space for the lifting and lowering movement of the stirring rod 202, and can accommodate other auxiliary components, making the equipment structure more compact. At the same time, the spline connection realizes the synchronous rotation of the stirring rod 202 and the transmission sleeve 201, and allows the stirring rod 202 to be freely lifted and lowered along the axial direction, thereby enhancing the flexibility of stirring. In addition, the transmission sleeve 201 is installed on the top side of the purification tank 1 through a bearing, which reduces rotational friction and improves power transmission efficiency.

[0047] To achieve the treatment of papermaking wastewater, the drive mechanism 3 includes a drive motor 302 and a support shaft 306 arranged on the top side of the purification tank 1. A bevel plate 307 is fixed to the top of the support shaft 306. The drive motor 302 is a dual-shaft motor. Transmission gears 303 are fixed to both output shafts of the drive motor 302. The outer portion of the bottom transmission gear 303 is meshed with a first driven gear 304 fixed to the outer surface of the transmission sleeve 201, and the outer portion of the top transmission gear 303 is meshed with a second driven gear 305 fixed to the support shaft 306. Specifically, the drive motor 302 is a dual-shaft motor that can simultaneously drive two sets of transmission gears 303 at the bottom and top, achieving a single motor driving multiple mechanisms to work in coordination, reducing the number of motors, energy consumption, and equipment costs. The bottom transmission gear 303 drives the transmission sleeve 201 to rotate through the first driven gear 304, thereby driving the stirring rod 202 to rotate; the top transmission gear 303 drives the support shaft 306 to rotate through the second driven gear 305, achieving power diversion and improving transmission efficiency.

[0048] The drive mechanism 3 further includes a connecting frame 308 disposed at the top of the stirring rod 202. The top of the stirring rod 202 is rotatably connected to one end of the connecting frame 308. A contact roller 309 is fixed to the outer surface of the connecting frame 308, which abuts against the upper surface of the inclined disk 307. A frame 301 supporting the drive motor 302 is fixed to the top side of the purification tank 1, and the bearing of the support shaft 306 is mounted on the frame 301. The inclined disk 307 at the top of the support shaft 306 cooperates with the contact roller 309 on the connecting frame 308 to convert the rotational motion of the support shaft 306 into the lifting motion of the stirring rod 202. The lifting motion of the stirring rod 202 enhances the mixing effect of the wastewater and the purifier, prevents sedimentation, and improves treatment efficiency.

[0049] In order to purify the sewage, the grinding structure 6 includes a grinding cylinder 601 arranged on the top side of the purification tank 1, a grinding head 603 is arranged inside the grinding cylinder 601, a connecting shaft 604 is fixed to the top side of the grinding head 603, and a discharge pipe 607 fixed to the inside of the purification tank 1 is welded to the bottom side of the grinding cylinder 601. The discharge pipe 607 extends into the interior of the purification tank 1, and the top outer surface of the connecting shaft 604 is rotatably connected to the other end of the connecting frame 308. The present application uses the knocking block 706 of the reciprocating structure 7 to regularly knock on the grinding cylinder 601, effectively preventing the powder from being blocked during the grinding and conveying process, ensuring the continuity of grinding and conveying, avoiding equipment shutdown due to blockage, and improving the stability and reliability of the equipment. In addition, the reciprocating motion of the grinding head 603 can effectively prevent the powder from being hardened in the grinding cylinder 601. Combined with the periodic knocking of the reciprocating structure 7, the risk of blockage is further reduced. The grinding head 603 has a conical shape, and the internal space of the grinding cylinder 601 is adapted to the shape of the grinding head 603 .

[0050] Specifically, a feeding pipe 602 is fixedly connected to the outer wall of the grinding cylinder 601, and a coaxial channel 605 is provided inside the connecting shaft 604 and the grinding head 603. By directly setting the grinding cylinder 601 on the top side of the purification tank 1 and connecting it to the interior of the tank through the discharge pipe 607, the equipment structure is simplified, the powder conveying path is reduced, and leakage and waste of powder during transportation are avoided. At the same time, the discharge pipe 607 extends to the interior of the purification tank 1, ensuring that the ground powder directly enters the wastewater treatment area, thereby improving the powder utilization rate.

[0051] To enable the rotation of the grinding head 603, a guide groove 606 is provided within the connecting shaft 604, which rolls with the ball bearing 704. The guide groove 606 is spirally arranged around the outer surface of the connecting shaft 604. The grinding head 603 is rotatably connected to the connecting frame 308 via the connecting shaft 604, and the ball bearing 704 rolls within the guide groove 606. This decouples the lifting and rotational motion of the grinding head 603. The reciprocating motion of the connecting frame 308 drives the grinding head 603 up and down, while the grinding head 603 can rotate freely during the lifting process, enhancing the uniformity of the grinding and the fineness of the powder.

[0052] It is worth mentioning that the connecting shaft 604 is linked to the drive mechanism 3 through the connecting frame 308, directly utilizing the power of the drive motor 302, reducing the need for an additional power source and lowering energy consumption. The lifting movement of the grinding head 603 is driven by the inclined disk 307, sharing the same power source as the lifting movement of the stirring rod 202, thereby improving power utilization efficiency. In addition, the ground powder is directly fed into the purification treatment tank 1 through the discharge pipe 607, where it is quickly mixed with the wastewater, shortening the dissolution time of the purifier and improving the treatment efficiency. The increased fineness of the powder increases its contact area with the wastewater, accelerating the purification reaction and improving the wastewater treatment effect.

[0053] In order to prevent the blockage of the purified solid block, the reciprocating structure 7 includes a limit assembly, an abutment assembly, a knocking assembly and a driving plate 709; the abutment assembly includes an elastic guide rod 703 provided on the limit assembly and a ball 704 rotatably mounted on the elastic guide rod 703 away from the end of the limit assembly; the knocking assembly includes a swing shaft 705 rotatably provided on the limit assembly, a knocking block 706 is fixed to the bottom end of the swing shaft 705, a shaft 708 is fixed to the top end of the swing shaft 705, and the other end of the shaft 708 is fixed to the bottom end of the swing shaft 705. The bearing is equipped with a rolling wheel 710 that rolls with the drive plate 709. The drive plate 709 has a linear groove 7091 and a wave groove 7092 inside that match the rolling wheel 710. It should be noted that the shape of the knocking block 706 is compatible with the grinding cylinder 601, and a buffer pad 7061 is fixed to the inside of the knocking block 706. A connecting frame 707 that is rotatably connected to the connecting shaft 604 is fixed to the outer wall of the drive plate 709. The top of the wave groove 7092 is connected to the bottom of the linear groove 7091. The shape of the knocking block 706 closely matches the curvature of the outer wall of the grinding cylinder 601, ensuring that the knocking energy is concentrated on the easily blocked areas of the grinding cylinder 601, such as the interface with the feed pipe 607, thereby improving the anti-blocking effect. The buffer pad 7061 can absorb the impact of the knocking, preventing the grinding cylinder 601 from metal fatigue caused by repeated knocking, extending the life of the equipment, and reducing noise. The length of the wave groove 7092 plus the straight groove 7091 is adapted to the reciprocating distance of the stirring rod 202 and the grinding head 603. The buffer pad 7061 can be made of rubber or polyurethane.

[0054] In this embodiment, the limiting assembly includes a support base 701 fixed to the top side of the grinding cylinder 601. A limiting rod 702 is fixed within the support base 701. An elastic guide rod 703 is bolted to the left end of the limiting rod 702. A swing shaft 705 is rotatably mounted on the outer surface of the limiting rod 702 via a circular axis. The support base 701 is fixed to the top side of the grinding cylinder 601 and provides rigid support for the limiting rod 702, ensuring the installation position accuracy of the elastic guide rod 703 and swing shaft 705. The limiting rod 702 is rigidly connected to the grinding cylinder 601 through the support base 701, forming a stable reference frame, reducing component displacement caused by vibration during the grinding process and improving the operational stability of the equipment.

[0055] To further enhance the anti-clogging effect, the piston assembly 8 includes a piston cylinder 801 disposed outside the grinding structure 6. A piston block 802 is slidably disposed within the piston cylinder 801. A connecting rod 803 extending to the exterior of the piston cylinder 801 and connected to the drive mechanism 3 is fixed to the upper surface of the piston block 802. A delivery pipe 804 is disposed on the sidewall of the piston cylinder 801 between the grinding structure 6. Check valves are disposed within both the piston cylinder 801 and the piston block 802. One end of the delivery pipe 804 is connected to the end of the check valve via a flange, and the other end of the delivery pipe 804 is rotatably connected to the top end of the connecting shaft 604. By matching the rapid opening and closing characteristics of the check valve with the reciprocating motion of the piston assembly 8, pulsed spraying of the powder is achieved, improving the uniformity of mixing of the powder and wastewater.

[0056] The top end of connecting rod 803 extends outside piston cylinder 801 and is bolted to the bottom surface of connecting frame 308. A buffer spring 805, encircling the outside of connecting rod 803, is fixed between the top side of piston cylinder 801 and the bottom surface of connecting frame 308. Buffer spring 805 is compressed as connecting frame 308 descends, absorbing impact energy and reducing the rigid collision between piston block 802 and the end cap of piston cylinder 801, thereby lowering noise. Furthermore, the spring's elastic force compensates for minor deviations in the movement of connecting frame 308, ensuring smoother reciprocating motion of piston block 802 and minimizing pressure fluctuations during powder delivery. It should be noted that piston assembly 8 can also be used for infusion. By adjusting the piston stroke (e.g., by making the length of connecting rod 803 adjustable), the amount of liquid in a single pulse can be controlled, enabling on-demand quantitative dosing and avoiding overdosing or underdosing.

[0057] The working principle of the above embodiment is:

[0058] First, wastewater enters the purification tank 1 through the feed port 4. The drive motor 302 of the drive mechanism 3 transmits power to the first driven gear 304 and the second driven gear 305 through the transmission gear 303. The first driven gear 304 drives the transmission sleeve 201 to rotate, thereby driving the stirring rod 202 to rotate. The second driven gear 305 drives the support shaft 306 to rotate, stirring the wastewater and promoting mixing of the wastewater with the subsequently added purifying agent. At this time, the inclined plate 307 on the support shaft 306 rotates accordingly.

[0059] One end of the connecting frame 308 is rotatably connected to the top of the stirring rod 202, and the outer surface of the other end is fixed with an abutting roller 309 that abuts against the upper surface of the inclined plate 307. As the inclined plate 307 rotates, the abutting roller 309 rolls on the inclined plate 307, driving the connecting frame 308 to move up and down, thereby driving the stirring rod 202 to move up and down, thereby enhancing the stirring effect.

[0060] The purifier is added to the grinding cylinder 601 through the feeding pipe 602, and the grinding head 603 is connected to the connecting frame 308 via the connecting shaft 604 to achieve reciprocation. During the reciprocating process of the connecting frame 308, the elastic guide rod 703 and the ball 704 are limited, and the ball 704 rolls in the guide groove 606, causing the grinding head 603 to reciprocate during the reciprocating lifting process, thereby grinding the purified solid block and crushing the purified solid block into powder;

[0061] The grinding head 603 drives the reciprocating structure 7 and the piston assembly 8 during the reciprocating movement. When the reciprocating structure 7 is in operation, the driving plate 709 is lifted and lowered via the connecting frame 308, and during the movement of the driving plate 709, the wave groove 7092 pushes the rolling wheel 710, causing the swing shaft 705 to swing, thereby driving the knocking block 706 to periodically knock the grinding cylinder 601 to prevent powder from clogged.

[0062] When the piston assembly 8 is working, it drives the connecting rod 803 to push and pull the piston block 802 to generate pressure in the piston cylinder 801, and connects the channel 605 through the delivery pipe 804. As the grinding head 603 moves downward, the powder is pulse-sprayed into the purification tank 1 and mixed with the wastewater.

[0063] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods.

[0064] Any connection method can be implemented as long as it can achieve its beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply.

Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so its specific structural composition and working principle will not be described in detail in this embodiment.
