Description

TECHNICAL FIELD

With the continuous development of the national industry, the scale of such businesses is gradually expanding, and the total amount of wastewater produced is also increasing. Environmental protection has always been the focus of society, and the government's emphasis on environmental protection is increasing, and environmental protection policies are also tightening. For enterprises that produce wastewater, properly disposing of wastewater is not only a requirement for responding to the government's environmental protection policy, but also an inevitable choice for the sustainable development of enterprises. Effective wastewater treatment can reduce environmental pollution, protect ecological balance, and also help improve the social image and competitiveness of enterprises.

[0003] Traditionally, there are two main modes for wastewater treatment in such enterprises. One is to build a sewage treatment station with civil structures, which centrally processes wastewater by building large civil water pools and related treatment facilities. This method has certain advantages in treating large-scale wastewater and can achieve relatively stable treatment effects. The other is to install dispersed equipment on site, which installs multiple treatment devices on the production site to process wastewater on site to improve the timeliness of treatment.

[0004] However, these traditional wastewater treatment modes are obviously unsuitable for enterprises with strong production seasonality, small single cleaning water volume, and high pollutant concentration. For small water volume treatment needs, the construction volume of civil water pools is often much larger than the actual treatment needs in order to meet the structural requirements, which leads to high initial investment and poor economic efficiency. Moreover, fixed treatment facilities have poor flexibility and cannot adapt to the needs of seasonal production or relocation of enterprises, which can easily cause resource idling or waste, so further improvement is needed.

[0036] Referring to Figure 1 , Figure 2In the embodiment, the bottom of the sedimentation tank 13 is in the shape of a bucket, and can also be rectangular. The sedimentation tank 13 is provided with a filtering mechanism 2, which comprises a filtering assembly 21 and a driving assembly 22. The filtering assembly 21 comprises a fixed filtering plate 211 fixedly connected to the inner side wall of the inclined sedimentation tank 13, a pushing filtering plate 212 slidably connected to the fixed filtering plate 211, a blocking plate 3 arranged on the pushing filtering plate 212, and a control member 4 for controlling the rotation of the blocking plate 3 to intercept water. In the embodiment, the pushing filtering plate 212 and the fixed filtering plate 211 can be made of stainless steel filter screens, which have high strength and corrosion resistance. Alternatively, ceramic filtering plates can be used, which have better filtering effect. The fixed filtering plate 211 is provided with a falling opening 2121 for the falling of flocculation materials. The sedimentation tank 13 is provided with a collecting member 125 for collecting the flocculation materials falling from the falling opening 2121. The collecting member 125 comprises a collecting groove and a discharge pipe communicated with the collecting groove. The collecting member 125 is made of plastic material, which is light and corrosion resistant. Alternatively, the collecting member 125 can be made of metal material, which has higher strength.

[0037] The sliding connection between the pushing filtering plate 212 and the fixed filtering plate 211 can be achieved by the cooperation of a guide rail and a sliding block, so as to ensure the smooth movement of the pushing filtering plate 212. The pushing filtering plate 212 is provided with a plurality of pushing filtering plates 212, which are arranged in a stepped manner and slidably connected to each other.

[0038] The driving assembly 22 is used to drive the horizontal movement of the pushing filtering plate 212, so as to drive the pushing filtering plate 212 to push the flocculation materials on the fixed filtering plate 211. The driving assembly 22 comprises a driving plate 221 and a moving member 222 for driving the driving plate 221 to move back and forth along the horizontal direction.

[0039] In another embodiment, the upper surface of the pushing filtering plate 212 can be inclined downward toward the fixed filtering plate 211, so as to reduce the possibility of accumulation.

[0040] The water outlet end of the pipeline connected to the coagulation reaction tank 123 is arranged toward the pushing filtering plate 212. The blocking plate 3 is arranged at one end of the pushing plate close to the fixed filtering plate 211.

[0041] Reference Figure 2 , Figure 3The blocking plate 3 is rotationally connected to the pushing filter plate 212. The pushing filter plate 212 is provided with a rotation groove 2122 for rotationally mounting the blocking plate 3. The blocking plate 3 specifically includes a blocking section 31 and a connecting section 32 connected to the blocking section 31. A first rotating rod 33 is fixedly arranged at the connecting position between the connecting section 32 and the blocking section 31. The first rotating rod 33 is rotationally connected to the pushing filter plate 212. The control member 4 includes a first torsion spring coaxially sleeved on the first rotating rod 33. When the driving assembly 22 drives the pushing filter plate 212 to move away from the fixed filter plate 211, the first torsion spring forces the free end of the blocking section 31 to move away from the fixed filter plate 211. The free end of the connecting section 32 abuts against the fixed filter plate 211. The fixed filter plate 211 is provided with a guide surface. When the driving assembly 22 drives the pushing filter plate 212 to move towards the fixed filter plate 211, the free end of the connecting section 32 is driven by the guide surface to move towards the fixed filter plate 211, so that the blocking plate 3 is inclined as shown in Figure 4 .

[0042] Further, the free end of the blocking section 31 is provided with an abutting section 34 for abutting against the upper surface of the fixed filter plate. The abutting section 34 and the blocking section 31 can be arranged in an L-shaped rod or the abutting section 34 is arranged in an arc shape to clean the fixed filter plate 211. It should be noted that the end of the abutting portion of the pushing filter plate 212 can be provided with a wool yarn to further improve the cleaning of the fixed filter plate 211.

[0043] In another embodiment, as shown in Figure 5 , since the control member 4 includes the first torsion spring, when there are more and heavy flocculation, the blocking plate 3 is pressed to rotate. If it is desired to further improve the precipitation time of the flocculation, the control member 4 can further include a limiting block 41 arranged on the inner wall of the precipitation tank 13 to limit the free end of the connecting section 32 to move towards the pushing filter plate 212, so that the blocking plate 3 can be kept inclined.

[0044] The sewage treatment system 14 further processes the wastewater after precipitation. The sewage treatment system 14 can adopt an activated carbon filter device which can effectively adsorb harmful substances in water, or an ion exchange resin device which can remove heavy metal ions in water.

[0045] The dosing system 15 is used for adding reagents into the reaction tank 12. The dosing system 15 can include a reagent storage tank, a metering pump and a delivery pipe 2212. The reagent storage tank can be made of plastic material to prevent corrosion of the reagent. The metering pump can accurately control the addition amount of the reagent. The delivery pipe 2212 can be made of a corrosion-resistant rubber pipe.

[0046] The electrical control system controls the operation of the entire device. The electrical control system can include a control cabinet, sensors and controllers. Various electrical elements are installed in the control cabinet, sensors are used to detect the water level, water quality and other parameters of each pool body, and the controller controls the operation of each device according to the information fed back by the sensor.

[0047] The implementation principle of the movable integrated chemical precipitation treatment device is: the movable integrated chemical precipitation treatment device is designed through the integrated frame 1, which is convenient for overall movement and adapts to the seasonal production and relocation needs of enterprises. The wastewater enters from the water inlet pool 11, passes through the neutralization reaction pool 121, the mixing reaction pool 122 and the coagulation reaction pool 123 in turn, and under the stirring action of the medicament adding system 15 and the mechanical stirrer 124, chemical reaction occurs to form flocculation. The flocculation enters the sedimentation tank 13, and is pushed to the drop port 2121 by the push filter plate 212 of the filtering mechanism 2, and falls into the collection piece 125. The wastewater after sedimentation and filtration enters the sewage treatment system 14 for further treatment, and finally realizes effective treatment of the wastewater. Compared with the traditional wastewater treatment mode, the initial investment is reduced, the flexibility is improved, and the resource idling and waste are reduced.

[0048] Embodiment 2: Referring to Figure 6 The difference from embodiment 1 is that the number of blocking plates 3 is correspondingly arranged with the number of push filter plates 212. After being pressed by the flocculation, the free end of the blocking part will rotate downward, so that some flocculation flows, reducing the excessive flocculation flowing into the collection tank, and achieving a certain amount of control.

[0049] Embodiment 3: Referring to Figure 7 The difference from embodiment 1 is that the filtering assembly 21 is arranged at intervals along the height direction of the sedimentation tank 13, the filter holes on the push filter plate 212 and the fixed filter plate 211 are arranged to gradually decrease towards the bottom wall of the sedimentation tank 13, and the number of collection pieces 125 is correspondingly arranged with the number of filtering assemblies 21.

[0050] The plurality of filtering assemblies 21 can be arranged on one side as shown in Figure 7 , or staggered on both sides of the driving plate 221 as shown in Figure 8 . For the latter, the driving plate 221 is arranged at intervals along the height direction thereof and is provided with a plurality of water outlet grooves 2211 corresponding to the filtering assemblies 21. A telescopic guide plate 23 is arranged below the filtering assembly 21, the upper end of the guide plate 23 is arranged on the side away from the sedimentation tank 13 of the drop port 2121, and the lower end of the guide plate 23 is communicated with the water outlet groove 2211.

[0051] Embodiment 4: Referring to Figure 9Different from the embodiment 1, the cleaning assembly 5 is arranged in the sedimentation tank 13 to clean the pushing filter plate 212 closest to the driving plate 221, the cleaning assembly 5 comprises the spray head 51 arranged on the driving plate 221 and the water delivery component 52 connected with the spray head 51. In the embodiment, the spray head 51 can be a high-pressure spray head 51, which can generate a strong water pressure to effectively clean the pushing filter plate 212. In the embodiment, the spray head 51 is arranged in the width direction and the height direction of the driving plate 221, and a plurality of spray heads 51 arranged in the same horizontal direction are connected by a connecting pipe 511.

The first one-way valve 524 allows water to flow from outside the collection box 521 to inside the collection box 521, and the second one-way valve 525 allows water to flow from inside the collection box 521 to the water delivery pipe 526. When the driving plate 221 moves horizontally, the filter assembly 21 arranged on the right side of the driving plate 221 is taken as an example. When the driving plate 221 moves to the left, the piston rod 523 is pulled to make the collection box 521 flow into the collection box 521 through the first one-way valve 524. Then, when the driving plate 221 moves to the right, the water in the collection box 521 is squeezed to flow to the spray head 51 through the second one-way valve 525, the water delivery pipe 526, the delivery pipe 2212 and the connecting pipe 511, and is sprayed out. For the filter assembly 21 arranged on both sides of the driving plate 221, the two collection boxes 521 are arranged on both sides of the driving plate 221, and the piston rod 523 can be a telescopic rod for space consideration.

The water pump can be arranged in the sedimentation tank 13, and the water pipe is fixedly arranged in the driving plate 221 to make the water in the delivery pipe 2212 sprayed out through the spray head 51, thereby ensuring the stability of water supply. When the inclination angle is small, the former can be used to move the piston rod 523. The piston rod 523 can be a telescopic rod to adapt to the movement of the driving plate 221.

The control assembly 6 comprises the second torsion spring 61 coaxially sleeved and fixed to the second rotating rod 7, the gear 62 fixedly sleeved to the second rotating rod 7, and the rack 63 engaged with the gear 62. In the embodiment, the elastic coefficient of the second torsion spring 61 can be selected according to the adjustment requirement of the spray head 51. The second torsion spring 61 forces the spray direction of the spray head 51 to be arranged downward. The rack 63 is fixedly connected to the inner wall of the sedimentation tank 13 and arranged above the gear 62. The teeth on the rack 63 are arranged downward. The gear 62 and the rack 63 can accurately control the rotating angle of the spray head 51. During the movement of the spray head 51 on the driving plate 221, the gear 62 and the rack 63 are used to automatically adjust the angle, so as to realize the automatic cleaning and enhance the practicability of the device.
