Description

Technical Field

[0001] This invention relates to the field of industrial wastewater treatment technology, and in particular to a wastewater treatment device for the modification of environmentally friendly aluminum profiles. Background Technology

[0002] The modification of aluminum profiles generates a large amount of industrial wastewater, which needs to be treated before discharge. In the existing technology, the collected wastewater is pumped into an equalization tank for homogenization and equalization. Then, the pH value is precisely adjusted to a suitable range by adding acid or alkali, so that some heavy metal ions form hydroxide precipitates. After the initial reaction, the wastewater is introduced into a sedimentation tank, where suspended particulate matter and metal hydroxide flocs settle and separate under the synergistic effect of flocculants. The supernatant is then lifted into a multi-stage filter for deep filtration. Finally, after disinfection with ultraviolet light or sodium hypochlorite, it can meet the discharge standards or be reused.

[0003] Currently, most filters use granular filter media to adsorb and trap wastewater. During continuous operation, fine suspended solids, colloids, and newly formed micro-flocs in the wastewater are constantly intercepted by the packing layer. Impurities accumulate and deposit at the top of the packing layer. Over time, the gaps between the top packing layers become severely clogged, leading to a decrease in filtration efficiency. At this point, the entire wastewater treatment process must be interrupted to backwash the filter unit or remove and replace all the packing. During backwashing or packing replacement, the equipment is shut down. Each shutdown maintenance requires restarting and commissioning. During this period, the effluent quality is unstable, making it difficult to continuously and stably treat wastewater. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing technologies, such as the equipment being in a shutdown state during backwashing or packing replacement, requiring readjustment after startup, and the unstable effluent quality during this period, making it difficult to continuously and stably treat wastewater. Therefore, this invention proposes an environmentally friendly wastewater treatment device for aluminum profile modification.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an environmentally friendly wastewater treatment device for modified aluminum profiles, comprising a housing, with two parallel open cylinders connected to both sides of the housing. Each open cylinder has a guide rod on one side, and a first mounting plate is slidably connected to each guide rod. Each first mounting plate has a servo motor, and a connecting rod is fixedly connected to the output end of each servo motor. One end of each connecting rod extends into the open cylinder and is fixedly connected to a filter media assembly for wastewater filtration. Each filter media assembly has a limit plate rotatably connected to one side via a connecting shaft, and the limit plates at the same height are in contact with each other.

[0007] Preferably, the housing is provided with a perforated plate above the filter media assembly to buffer the downward flowing wastewater.

[0008] Preferably, the housing is provided with support bars at the bottom of the filter media assembly to support the filter media assembly and the limiting plate.

[0009] Preferably, the limiting plate is a stainless steel plate.

[0010] Preferably, it also includes a pneumatic unblocking mechanism, which includes a connecting pipe connected to the upper end of the open cylinder. A piston plate is slidably connected inside the connecting pipe, and a second mounting plate is provided on one side of the connecting pipe. A second telescopic cylinder is provided on the second mounting plate for driving the piston plate to move in the vertical direction.

[0011] Preferably, one bottom end of the connecting pipe is connected to a conduit, one end of the conduit is connected to a dispersing pipe, one side of the dispersing pipe is connected to a flushing pipe, and one end of the flushing pipe extends into the open cylinder for cleaning the lower surface of the filter media assembly.

[0012] Preferably, the flushing pipes are provided in a plurality of them and are distributed at equal intervals along the length of the dispersing pipe.

[0013] Preferably, it also includes an engagement-type stop mechanism, which includes a movable plate. A groove is provided on the first mounting plate, and the movable plate is slidably connected to the groove. A third mounting plate is mounted on the first mounting plate. The lower surface of the third mounting plate is provided with a third telescopic cylinder for driving the movable plate to move in the vertical direction. A gear is mounted on the connecting rod, and the lower surface of the movable plate is provided with a limiting tooth for limiting the gear.

[0014] Preferably, the bottom end of the limiting tooth is provided with a notch, the notch is provided with an elastic sleeve, and the bottom end of the elastic sleeve is provided with an elastic protrusion to reduce the collision intensity between the limiting tooth and the gear.

[0015] Preferably, the elastic sleeve and the elastic protrusion are an integral structure, and the elastic sleeve is a rubber sleeve.

[0016] The wastewater treatment equipment for the modification of environmentally friendly aluminum profiles proposed in this invention has the following advantages:

[0017] By using connecting rods, filter media components of different heights are sequentially retracted into the open cylinder for backwashing. This ensures that there is always a set of filter media components inside the shell to filter the wastewater. While cleaning the filter media components, the wastewater is continuously filtered. During the rinsing process, the quality of the filtered water remains stable, thus maintaining continuous and stable wastewater treatment and improving the wastewater treatment effect.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Example 1: Refer to Figure 1-3 An environmentally friendly wastewater treatment device for modifying aluminum profiles includes a housing 1. A wastewater inlet pipe is connected to the upper end of the housing 1, and a water outlet pipe is connected to the bottom end of one side of the housing 1. Two parallel open cylinders 2 are connected to both sides of the housing 1. A guide rod 3 is provided on one side of each open cylinder 2, and a first mounting plate 4 is slidably connected to each guide rod 3. A first telescopic cylinder 5 is provided on each open cylinder 2 to move the first mounting plate 4. A servo motor 6 is provided on each first mounting plate 4, and a connecting rod 7 is fixedly connected to the output end of each servo motor 6. One end of each connecting rod 7 extends into the open cylinder 2 and is fixedly connected to it. There is a filter media assembly 8 for wastewater filtration. The filter media assembly 8 cooperates with the open cylinder 2. Each filter media assembly 8 has a limit plate 9 rotatably connected to one side via a connecting shaft. The limit plate 9 is made of stainless steel. Limit plates 9 at the same height are in contact with each other. A perforated plate 10 is provided above the filter media assembly 8 inside the housing 1 to buffer the downward flowing wastewater. A support bar 11 is provided at the bottom of the filter media assembly 8 inside the housing 1 to support the filter media assembly 8 and the limit plate 9. A cleaning water inlet pipe 12 is connected to the upper end of each open cylinder 2 for cleaning the filter media assembly 8. A drain pipe 13 is connected to the bottom end of each open cylinder 2.

[0029] Working principle:

[0030] Wastewater generated from aluminum profile modification enters the housing 1 through the wastewater inlet pipe. The wastewater falls onto the perforated plate 10 above and flows downwards evenly after being buffered by the perforated plate 10, preventing the water flow from concentrating and impacting the filter media assembly 8. Two limiting plates 9 at the same height are in close contact with each other in the filtration state, and together with the bottom support of the support strip 11, they form a lateral seal to ensure that the wastewater passes through the filter media assembly 8 and prevent untreated wastewater from flowing directly down the filter media through the side gaps. Under the action of gravity, the wastewater flows through the two layers of filter media assembly 8 in sequence. Each layer of filter media assembly 8 adsorbs suspended solids in the wastewater and filters the wastewater. The filtered wastewater collects at the bottom of the housing 1 and is finally discharged from the outlet pipe to enter the subsequent treatment device for further treatment.

[0031] Two first telescopic cylinders 5 at the same height are activated at set intervals. The first telescopic cylinders 5 at different heights are activated alternately. The two first telescopic cylinders 5 at the upper level are activated, while the two first telescopic cylinders 5 at the lower level are not activated. After the first telescopic cylinders 5 at the upper level are activated, they drive the first mounting plate 4 to move a set distance away from the open cylinder 2. The first mounting plate 4 moves smoothly under the guidance of the guide rod 3. The first mounting plate 4 drives the connecting rod 7 to move through the servo motor 6. The connecting rod 7 drives the filter material assembly 8 to move a set distance towards the open cylinder 2. The filter material assembly 8 drives the limiting plate 9 to move. After moving a set distance, the filter material assembly 8 is located inside the open cylinder 2. The filter material assembly 8 cooperates with the open cylinder 2 to prevent cleaning water from being released from the contact point between the filter material assembly 8 and the open cylinder 2. The limiting plate 9 is located at the connection point between the shell 1 and the open cylinder 2 to block and seal the connection point between the shell 1 and the open cylinder 2, preventing wastewater in the shell 1 from passing through the connection point between the shell 1 and the open cylinder 2 and entering the open cylinder 2.

[0032] After the upper servo motor 6 starts, it drives the connecting rod 7 to rotate clockwise a set number of times. The connecting rod 7 drives the filter media assembly 8 to rotate a set number of times, so that the clogging surface of the filter media assembly 8 is facing downward. The external water supply mechanism introduces cleaning water into the cleaning water inlet pipe 12. The cleaning water inlet pipe 12 introduces cleaning water into the open cylinder 2. The cleaning water in the open cylinder 2 falls on the upper end of the filter media assembly 8. Under the action of gravity, the cleaning water flows downward through the filter media assembly 8 and washes the clogging surface of the filter media assembly 8, so that the debris is separated from the filter media assembly 8, so that the filter media assembly 8 restores its filtration performance and does not clog. The sewage generated during rinsing is released from the drain pipe 13. After rinsing, the first telescopic cylinder 5 drives the first mounting plate 4 to move and reset. The filter media assembly 8 drives the limiting plate 9 to move and reset. The two limiting plates 9 at the same height contact each other to form a seal and restore the filtration state.

[0033] During the wastewater treatment process, filter media components 8 of different heights are sequentially retracted into the open cylinder 2 for backwashing without stopping the machine. While backwashing, a set of filter media components 8 is always present in the shell 1 to filter the wastewater. While cleaning the filter media components 8, the wastewater is continuously filtered. During the rinsing, the water quality after filtration is kept stable, and the wastewater is continuously and stably treated, thus improving the wastewater treatment effect.

[0034] Example 2: When backwashing the filter media assembly 8 by introducing cleaning water into the open cylinder 2, some suspended solids have a strong adhesion to the filter media assembly 8, and gravity rinsing with cleaning water alone cannot effectively remove the adhered suspended solids, thus reducing the backwashing effect on the filter media assembly 8. (Refer to...) Figure 4-5As another preferred embodiment of the present invention, the difference from embodiment 1 is that it also includes a pneumatic unblocking mechanism 14. The pneumatic unblocking mechanism 14 includes a connecting pipe 141, which is connected to the upper end of the open cylinder 2. A piston plate 142 is slidably connected inside the connecting pipe 141. A second mounting plate 143 is provided on one side of the connecting pipe 141. A second telescopic cylinder 144 is provided on the second mounting plate 143 for driving the piston plate 142 to move in the vertical direction. A conduit 145 is connected to the bottom end of one side of the connecting pipe 141. A dispersion pipe 146 is connected to one end of the dispersion pipe 146. A flushing pipe 147 is connected to one side of the dispersion pipe 146. One end of the flushing pipe 147 extends into the open cylinder 2 for cleaning the lower surface of the filter material assembly 8. Several flushing pipes 147 are provided and are evenly distributed along the length direction of the dispersion pipe 146.

[0035] Working principle:

[0036] When the cleaning water is introduced into the open cylinder 2, the second telescopic cylinder 144 is activated and drives the piston plate 142 to move downward. After the piston plate 142 moves downward, the volume of the communication space between the connecting pipe 141 and the open cylinder 2 is reduced. After the piston plate 142 moves downward, the gas in the connecting pipe 141 is squeezed into the upper part of the open cylinder 2, increasing the pressure of the space formed between the filter media assembly 8 and the upper part of the open cylinder 2. This pressurizes the cleaning water in the upper part of the filter media assembly 8, increases the speed at which the cleaning water passes through the filter media assembly 8, and increases the impact force on the adhering suspended matter when the water flow separates from the filter media assembly 8, thus separating the adhering suspended matter from the filter media assembly 8.

[0037] Simultaneously, a portion of the gas in the connecting pipe 141 is introduced into the conduit 145, and the gas in the conduit 145 is introduced into the dispersion pipe 146. The gas in the dispersion pipe 146 is released from several flushing pipes 147. The gas released from the several flushing pipes 147 blows the blockage surface of the filter media assembly 8. After the blowing gas is combined with the downward pressurized water flow, it effectively separates the adhering suspended matter from the filter media assembly 8, preventing floating matter from adhering to the filter media assembly 8 and improving the flushing effect of the filter media assembly 8.

[0038] Example 3: When the piston plate 142 moves downward, it forces the gas in the connecting pipe 141 into the upper part of the open cylinder 2. The gas entering the upper part of the open cylinder 2 pressurizes the filter media assembly 8, which easily causes the filter media assembly 8 to rotate to a certain extent. After the filter media assembly 8 rotates, its upper and lower surfaces become inclined. The water flow introduced into the open cylinder 2 accumulates at the lower end of the upper surface of the filter media assembly 8, resulting in poor rinsing effect at the upper end of the upper surface of the filter media assembly 8 and uneven rinsing of the filter media assembly 8. (Refer to...) Figure 6-8As another preferred embodiment of the present invention, the difference from embodiment 2 is that it also includes a biting stop mechanism 15. The biting stop mechanism 15 includes a movable plate 151. A groove 152 is provided on the first mounting plate 4. The movable plate 151 is slidably connected to the groove 152. A third mounting plate 153 is mounted on the first mounting plate 4. A third telescopic cylinder 154 for driving the movable plate 151 to move in the vertical direction is provided on the lower surface of the third mounting plate 153. A gear 156 is mounted on the connecting rod 7. A limiting tooth 155 for limiting the gear 156 is provided on the lower surface of the movable plate 151. A notch 157 is provided at the bottom end of the limiting tooth 155. An elastic sleeve 158 is provided on the notch 157. An elastic protrusion 159 is provided at the bottom end of the elastic sleeve 158 to reduce the collision intensity between the limiting tooth 155 and the gear 156. The elastic sleeve 158 and the elastic protrusion 159 are an integral structure. The elastic sleeve 158 is a rubber sleeve.

[0039] Working principle:

[0040] When the cleaning water is introduced into the upper part of the open cylinder 2 through the cleaning water inlet pipe 12, the third telescopic cylinder 154 is started and drives the movable plate 151 to move downward by a set distance. The movable plate 151 moves smoothly under the guidance of the slide groove 152. The movable plate 151 drives the limiting tooth 155 to move, and the limiting tooth 155 drives the elastic sleeve 158 to move. The limiting tooth 155 is inserted into the tooth gap of the gear 156 through the elastic sleeve 158. After the elastic sleeve 158 cooperates with the elastic protrusion 159, the collision intensity when the limiting tooth 155 is inserted into the tooth gap of the gear 156 is reduced.

[0041] After the limiting tooth 155 engages with the gear 156, the connecting rod 7 is locked. The connecting rod 7 limits and fixes the filter media assembly 8. When the piston plate 142 moves downward and forces the gas in the connecting pipe 141 into the upper part of the open cylinder 2, the gas entering the upper part of the open cylinder 2 pressurizes the filter media assembly 8. Under the limiting and fixing of the connecting rod 7, the mesh frame 8 of the filter packing will not rotate, so that the filter media assembly 8 is placed horizontally in the open cylinder 2, and the introduced cleaning water is evenly distributed at the upper end of the filter media assembly 8, so as not to reduce the rinsing effect of the filter media assembly 8.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
