Description

Technical Field

[0001] The present invention belongs to the field of sewage treatment equipment, and in particular, relates to a sewage treatment equipment and a wastewater treatment process for the production of Chinese herbal medicine slices. Background Art

[0002] In the wastewater treatment process, the wastewater usually needs to be transported to a flocculation sedimentation tank and flocculants are added to the wastewater to flocculate and precipitate the suspended matter in the wastewater.

[0003] Chinese patent CN105502549B discloses a copolymerization flotation tank and a water purification method, in which a folding plate is arranged in the flocculation tank, and the turbulent shear force generated by the folding plate drives the particles to collide and flocculate, which can improve the flocculation speed and flocculation effect. However, the folding plate is fixedly arranged, and the spacing between the folding plates cannot be adjusted. In the wastewater treatment process, due to the influence of factors such as fluctuations in the production process of the enterprise, the amount of wastewater generated and the amount of wastewater treated will be in a fluctuating state. In order to meet the wastewater treatment needs, the folding plates in the flocculation tank need to be set according to the maximum wastewater discharge of the enterprise. In this way, when the wastewater discharge is small, the wastewater flow rate between the folding plates in the flocculation tank will be lower than the optimal flocculation flow rate. At this time, the turbulent shear effect generated by the folding plate is reduced, which reduces the flocculation effect of suspended matter in the wastewater, thereby reducing the wastewater treatment effect.

Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0040] Embodiment 1

[0041] See also Figure 1-Figure 3 As shown, the present invention is a wastewater treatment equipment, including a flocculation tank 1 and a plurality of folding plates 2 arranged in sequence and installed in the flocculation tank 1, the plurality of folding plates 2 are sequentially provided with diversion ports 21 staggered in an upper and lower manner, and the flocculation tank 1 is also provided with a spacing adjustment mechanism 3 for adjusting the spacing between adjacent folding plates 2 and a locking mechanism 4 for locking and fixing the folding plates 2; the spacing adjustment mechanism 3 includes a cross connecting rod 34, a sliding support assembly and a telescopic drive assembly, the sliding support assembly is installed in the side wall of the flocculation tank 1 for slidingly supporting the plurality of folding plates 2, and the cross connecting rod 34 is respectively connected to the plurality of folding plates 2 by a plurality of cross fulcrums therein. The telescopic drive assembly can drive the cross link 34 to contract or expand, so that the cross link 34 drives the multiple folding plates 2 to contract or expand synchronously; the locking mechanism 4 includes a friction locking strip 41, multiple lifting locking assemblies and a lifting drive assembly. The friction locking strip 41 is fixedly installed in the side wall of the flocculation tank 1 and is located below the sliding support assembly. The multiple lifting locking assemblies are sequentially installed in the sliding support assembly and can slide synchronously with the sliding support assembly. The lifting drive assembly can drive the multiple lifting locking assemblies to move up and down, and the lifting locking assembly can lock and fix the sliding support assembly to the top surface of the friction locking strip 41 when it moves downward;

[0042] Specifically, when the wastewater treatment equipment is working, the cross link 34 is first driven to contract or expand through the telescopic driving assembly, so that the cross link 34 drives the multiple folding plates 2 to contract or expand synchronously, so that the multiple folding plates 2 can be moved and adjusted at the same time according to the wastewater flow rate, so that the adjacent folding plates 2 are at an appropriate distance; then the multiple lifting and locking assemblies are driven to move downward synchronously through the lifting and lowering driving assembly, and the corresponding sliding support assembly can be locked and fixed to the top surface of the friction locking strip 41 when the lifting and lowering locking assembly moves downward, so that the corresponding folding plate 2 is locked to achieve synchronous locking of the multiple folding plates 2; finally, the wastewater mixed with flocculant is sent to one end of the flocculation tank 1, so that the wastewater is diverted and transported to the other end of the flocculation tank 1 through the folding plate 2 and the guide port 21 in the flocculation tank 1, and the turbulent shear force generated by the folding plate 2 during the transportation of the wastewater drives the suspended particles in it to collide and flocculate;

[0043] When the wastewater flow rate increases, the flow velocity of the wastewater between the adjacent folded plates 2 increases, and the shear force increases, the spacing between the adjacent folded plates 2 is adjusted to increase, thereby increasing the flow channel width, reducing the wastewater flow rate and the shear force, and preventing the large particles after flocculation from colliding and dispersing again due to excessive shear force. When the wastewater flow rate decreases, the flow velocity of the wastewater between the adjacent folded plates 2 decreases, and the shear force decreases, the spacing between the adjacent folded plates 2 is adjusted to decrease, thereby reducing the flow channel width, increasing the wastewater flow rate and the shear force, and improving the collision flocculation effect of the particles in the wastewater. Effect; thus, by adjusting the spacing between the folding plates 2, the flocculation treatment effect of the flocculation tank 1 on wastewater with different flow rates can be guaranteed. At the same time, during adjustment, the cross connecting rod 34 can be contracted to synchronously move and adjust all the folding plates 2, making the adjustment process of the folding plates 2 more convenient and quick; through the cooperation of the friction locking strip 41, the lifting drive assembly and the multiple lifting locking assemblies, the synchronous locking of the multiple folding plates 2 can be achieved, thereby improving the stability of the folding plates 2 when installed in the flocculation tank 1, preventing the folding plates 2 from shaking and displacing under the impact of wastewater, and ensuring the normal and stable operation of the flocculation tank 1.

[0046] Specifically, when the spacing of the folding plates 2 needs to be adjusted, the driving wheel 37 is driven to rotate by adjusting the motor 38. When the driving wheel 37 rotates clockwise, the driving wheel 37 drives the transmission belt 311 on the left side of the lower part to move upward for transportation, so that the sliding seat 39 is pulled to the left by the cooperation of the transmission belt 311 and the left guide wheel 310. At the same time, the sliding seat 39 stretches and unfolds the cross link 34 by adjusting the driving rod 35. When the cross link 34 is unfolded, the corresponding sliding support block 33 is driven to slide and unfold to the left in the guide groove 31 through the cross fulcrum therein, and then the folding plate 2 is driven to move and unfold to the left in the flocculation tank 1 through the sliding support block 33, so as to adjust and increase the spacing between adjacent folding plates 2.

[0047] When the driving wheel 37 rotates counterclockwise, the driving wheel 37 drives the transmission belt 311 on the right side of the lower part to move upward for transportation, so that the sliding seat 39 is pulled to the right through the cooperation of the transmission belt 311 and the right guide wheel 310, and at the same time, the sliding seat 39 pushes the cross link 34 to the right and contracts through the adjusting driving rod 35, and when the cross link 34 contracts, the corresponding sliding support block 33 is driven to slide and contract to the right in the guide groove 31 through the cross fulcrum therein, and then the folding plate 2 is driven to move and contract to the right in the flocculation tank 1 through the sliding support block 33, so as to adjust and reduce the distance between adjacent folding plates 2;

According to the size of the retracted or expanded stroke of the cross-link 34, a transmission belt 311 of corresponding length can be used for transmission, so that the telescopic stroke of the cross-link 34 will not be limited by the stroke of the telescopic drive assembly, which facilitates the cross-link 34 to perform a wide range of telescopic adjustment.

[0049] Furthermore, the sliding support block 33 is sealingly slidably mounted in the guide groove 31, one end of the sliding support block 33 is provided with a receiving slide groove 315, a telescopic sealing plate 316 is slidably mounted inside the receiving slide groove 315, the telescopic sealing plate 316 is sealingly slidably mounted in the guide groove 31, and the other end of the telescopic sealing plate 316 is fixedly connected to one end of another adjacent sliding support block 33; one end of the most distal sliding support block 33 is fixedly mounted with a tail end sealing slide plate 36, the tail end sealing slide plate 36 is sealingly slidably mounted in the guide groove 31, and one end of the tail end sealing slide plate 36 is telescopically slidably inserted in the side wall of the flocculation tank 1;

[0050] Among them, the sliding support block 33 and the telescopic sealing plate 316 are staggeredly distributed in sequence and the sliding seals are arranged in the guide groove 31, and then the tail end sealing slide plate 36 at the end of the guide groove 31 is used to seal the guide groove 31 to prevent the wastewater in the flocculation tank 1 from leaking through the guide groove 31 into the cavity where the spacing adjustment mechanism 3 and the locking mechanism 4 are installed on the side wall of the flocculation tank 1, so as to prevent the spacing adjustment mechanism 3 and the locking mechanism 4 from being corroded and rusted by the wastewater, and to improve the service life of the spacing adjustment mechanism 3 and the locking mechanism 4.

[0051] Furthermore, the inner end of the sliding support block 33 is fixedly installed with a mounting plate 32 located inside the flocculation tank 1. One side of the mounting plate 32 slides and fits tightly against the inner wall of the flocculation tank 1, and the other side of the mounting plate 32 is fixedly connected to one end of the folding plate 2. By arranging mounting plates 32 that slide and fit tightly against the inner wall of the flocculation tank 1 on both sides of the folding plate 2, the stability of the folding plate 2 in the flocculation tank 1 can be improved, and at the same time, the folding plate 2 can be moved in the flocculation tank 1 to adjust the spacing.

[0052] Embodiment 3

[0053] See also Figure 4-Figure 6 , Figure 8 As shown, the difference between this embodiment and the above embodiment is that the lifting drive assembly includes a transmission shaft 42, a locking motor 43 and a driving shaft 46. The transmission shaft 42 is rotatably installed in the side wall of the flocculation tank 1, and the transmission shaft 42 is arranged parallel to the guide groove 31. A transmission bevel gear 44 is fixedly installed on one end of the transmission shaft 42. The driving shaft 46 is rotatably installed in the side wall of the flocculation tank 1 and is arranged vertically with the transmission shaft 42. An active bevel gear 45 meshing and transmission-connected with the transmission bevel gear 44 is fixedly installed on the driving shaft 46. The locking motor 43 is fixedly installed in the inner wall of the flocculation tank 1 and is transmission-connected with one end of the driving shaft 46. The lifting locking assembly includes a lifting slide 411 and a screw 412. The lifting slide 411 is opened on the outside of the sliding support block 33. On the bottom surface of the side end, a friction locking block 414 is slidably installed inside the lifting slide 411, and the screw 412 is rotatably installed on the upper end of the sliding support block 33, and the bottom end of the screw 412 is provided with an external thread 413 that is transmission-connected to the friction locking block 414; the lifting locking assembly also includes a transmission bevel gear 2 47, a spline groove 48 and a driven bevel gear 49, the spline groove 48 is provided on the outer surface of the transmission shaft 42, the transmission bevel gear 2 47 is slidably installed on the surface of the transmission shaft 42 through the spline groove 48, and an L-shaped plate 410 is rotatably installed on the back of the transmission bevel gear 2 47, the horizontal end of the L-shaped plate 410 is rotationally connected to the upper end of the screw 412, and the driven bevel gear 49 is fixedly installed on the top of the screw 412 and meshes with the transmission bevel gear 2 47 for transmission connection;

[0054] Among them, the top surface of the friction locking strip 41 and the bottom surface of the friction locking block 414 are both provided with friction grooves. When the flocculation tank 1 is working, the friction locking block 414 abuts against the top surface of the friction locking strip 41, so that the friction locking block 414 is locked and fixed on the friction locking strip 41 by friction force, and then the sliding support block 33 and the folding plate 2 are locked and fixed, thereby improving the stability of the folding plate 2 installed in the flocculation tank 1. When it is necessary to adjust the spacing of the folding plate 2, the locking motor 43 is used to drive the driving shaft 46 and the active bevel gear 45 to rotate. When the active bevel gear 45 rotates, it engages and drives the transmission bevel gear 1 44 to rotate, thereby driving the transmission shaft 42 and the transmission bevel gear 2 47 to rotate. The transmission bevel gear 2 47 engages and drives the driven bevel gear 49 to rotate, thereby driving the screw 412 to rotate. When the screw 412 rotates The friction locking block 414 is driven to move upward by the external thread 413 at the lower end, so that the friction locking block 414 is separated from the friction locking strip 41, thereby releasing the lock. Thereafter, when the spacing between the sliding support block 33 and the folding plate 2 is adjusted, the sliding support block 33 drives the friction locking block 414, the screw 412, the driven bevel gear 49 and the L-shaped plate 410 to move synchronously. At the same time, the L-shaped plate 410 drives the transmission bevel gear 2 47 to slide synchronously on the transmission shaft 42 along the spline groove 48, so that the transmission bevel gear 2 47 and the driven bevel gear 49 are always in a meshing state. When the spacing adjustment is completed, the locking motor 43 is driven in reverse to drive the friction locking block 414 to reset downward, and then abut and lock against the top surface of the friction locking strip 41 again to lock the sliding support block 33 and the folding plate 2.

[0058] Then, the lifting driving assembly drives the multiple lifting locking assemblies to move downward synchronously.
