Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a sewage treatment device for environmental engineering. Background Art

[0002] Environmental protection is crucial for achieving my country's "dual carbon" development goals and implementing the principles of ecological civilization. Wastewater treatment, a key component of environmental protection, can effectively improve the quality of my country's water resources. High-quality wastewater treatment is also crucial for improving the urban environment. Only effective wastewater treatment that meets the current realities of cities can effectively enhance people's quality of life. Furthermore, with the continuous improvement and expansion of urbanization in my country, the population and urban population density are gradually increasing, which will increase the total amount of wastewater discharged and put pressure on wastewater treatment. If wastewater is not properly treated, it will directly contaminate available water resources. In severe cases, it can cause irreversible water pollution and threaten people's health. Therefore, sewage treatment is imperative. We must strengthen our understanding and awareness of sewage treatment, actively utilize diverse sewage treatment technologies, increase the utilization rate of water resources, and enhance the effectiveness of sewage treatment. This will ensure a steady improvement of the urban environment and promote the achievement of my country's long-term sustainable development strategy.

[0003] To address this technical problem, those skilled in the art have designed several sewage treatment devices. For example, Chinese patent CN210261365U discloses a sewage treatment device for environmental engineering. After sewage enters a tank, it reacts with a drug discharged from a spraying device, is filtered through multiple filters, and finally flows out through a drain hole at the bottom of the tank, achieving a purifying effect. However, such devices still have many drawbacks. For example, to replace the filters, the top must be opened and all filters removed, and the bottom filter cannot be replaced individually, which reduces the efficiency of the device during use. The unnecessary disassembly of the filters also reduces the durability of the filter and tank. Furthermore, bacteria in the sewage can decompose organic matter, easily producing hydrogen sulfide and methane gas in the water, posing a safety hazard. Furthermore, sewage in daily life comes in many forms, and there is no guarantee that the filtered sewage is free of solid impurities. When solid impurities flow into the tank, they can clog the filter device, affecting the proper functioning of the entire filter. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all 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.

[0030] As mentioned in the background technology, when replacing the filter, it is necessary to open the top and remove all the filters. The bottom filter alone cannot be replaced directly, which reduces the efficiency of the equipment during use. The unnecessary disassembly of the filter reduces the durability of the filter and the tank body. In addition, the bacteria in the sewage will decompose organic matter on their own, easily producing hydrogen sulfide and methane gas in the water, posing a certain safety hazard. Secondly, there are many forms of sewage in life, and it cannot be guaranteed that there are no solid impurities in the sewage being filtered. When solid impurities flow into the tank body, it will cause the filter device to be blocked, which will affect the normal operation of the entire filter device.

[0031] In order to improve the above problems, the present application proposes a sewage treatment device for environmental engineering, which can replace the filter screen separately by opening the box door, thereby improving work efficiency; discharging oxygen in the storage chamber helps to decompose particles in the water more effectively and prevent the production of hydrogen sulfide and methane gas in the water, and filters solid matter in the sewage before purification, reducing the probability of filter screen clogging when the sewage treatment device is purifying and filtering sewage, thereby improving the work efficiency of the entire sewage treatment device.

[0032] See Figure 1 、 2 As shown, according to an embodiment of the present application, a sewage treatment device for environmental engineering is provided.

[0033] It includes: a first tank body 1, a first filter screen 3, a push rod compression assembly, a connecting platform 5, an inflation device, a second tank body 7, a box door 9, a filter assembly, and a gas transmission device; wherein,

[0034] The bottom of the first tank body 1 is connected to the ground through a plurality of retractable brackets 2, and a support block 4 is provided in the middle of the relative inner wall of the first tank body 1; the first filter screen 3 is arranged horizontally, and its edges are respectively connected to the inner wall of the first tank body 1 and the side wall of the support block 4; a mounting plate 32 corresponding to the first filter screen 3 is provided on the other side of the support block 4, and the inner cavity of the first tank body 1 can be divided into a to-be-filtered area 42 and a filtering area 43 by the first filter screen 3 and the mounting plate 32; the push rod compression assembly is arranged in the to-be-filtered area 42 and is installed on the top of the mounting plate 32, and its action end can slide along the top end face of the first filter screen 3; a closable opening 6 corresponding to the first filter screen 3 is provided on the tank wall of the to-be-filtered area 42 of the first tank body 1, and the external connection of the closable opening 6 It is connected to a connecting platform 5; the inflation device is arranged in the filtering area 43, connected to the bottom end of the support block 1 4, and its air outlet end corresponds to the first filter screen 3; the high-pressure tank body 10 is used to provide high-pressure gas for the push rod compression assembly and the inflation device; the second tank body 7 is connected to the first tank body 1 through a water pipe 8, and an air outlet pipe 8 is provided on the top of the second tank body 7; a box door 9 is provided on one side wall, and the filter assembly inside the second tank body 7 is replaced by opening the box door 9; and the inner wall of the second tank body 7 is provided with a support block 2 4; the filter assembly is arranged inside the second tank body 7, and after the sewage passes through the first tank body 1 for the first filtration, it enters the second tank body 7 through the water pipe 8. In this process, the sewage is filtered for the second time through the filter assembly; the gas transmission device is arranged on the top of the filter assembly through the support block 21.

[0035] It should be understood that the advantages of the solution are that when sewage enters the first tank body 1, solid matter in the sewage is screened out through the first filter screen 3, preventing the solid flow from flowing into the second tank body 7 and causing blockage of the filter assembly, affecting the normal operation of the entire sewage treatment device; the second tank body 7 is provided with a door 9 on the front, which is used to replace the filter screen inside the second tank body, and one of the filter screens can also be replaced individually, which greatly improves the replacement efficiency; a gas transmission device is provided inside the second tank body 7, and when sewage enters the first storage chamber 36, the gas transmission device discharges oxygen, which is fully combined with the sewage and reacts with the bacteria in the sewage to prevent hydrogen sulfide and methane gas from being produced in the water, thereby improving the safety of the sewage treatment device.

[0036] In some specific embodiments, the push rod compression assembly includes: a push rod 11; wherein,

[0037] The push rod 11 is arranged on the top of the mounting plate 32, and one end of the push rod 11 is connected to the high-pressure tank body 10 through the gas pipe 12; the other end is provided with a push plate 13; when the closable opening 6 is opened, the high-pressure tank body 10 compresses the gas as a power source, and compresses the gas into the push rod 11 through the gas pipe 12. Under the action of the air pressure, the push plate 13 extends forward in a straight line to the closable opening 6, and after pushing the solid objects on the upper part of the first filter screen 3 to the connecting platform 5, the high-pressure tank body 10 releases the air to make the push plate 13 return to its original position, and the closable opening 6 is closed.

[0038] Specifically, the push rod 11 is parallel to the first filter screen 3 , cotton protective pieces are arranged around the push plate 13 , and a plurality of through holes are arranged on the top of the push plate 13 .

[0039] It can be understood that under the action of the compression of the high-pressure tank body, the push rod 11 moves forward, and the cotton guard on the push plate 13 can effectively clean the solid objects on the movement path, so that the outer surface of the first filter 3 is clean; during the reciprocating compression process of the push plate 13, the through hole on the top of the push plate 13 discharges the sewage flowing into it; prevents the push rod 11 and the push plate 13 from having too much sewage inside, causing the push plate 13 to be unable to return to its original position, affecting the normal operation of the push rod 11, and avoiding damage to the push plate 13.

[0040] In some specific embodiments, the inflation device includes: an inflation plate 14, an inflation head 15, and a columnar port 16; wherein,

[0041] The two ends of the inflation plate 14 are respectively connected to the support block 4 and the inner wall of the first tank body 1, and the inflation plate 14 is below the first filter screen 3; a cavity is provided in the inflation plate 14; the inflation plate 14 is connected to the high-pressure tank body 10 through a gas pipe 12; the inflation head 15 is provided on the top of the inflation plate 14, and the inflation head 15 is communicated with the internal cavity of the inflation plate 14. The high-pressure tank body 10 compresses the gas and transmits it to the inflation plate 14 through the gas pipe 12. The gas flows to the first filter screen 3 through the inflation head 15. Under the action of the gas flow, the solid impurities on the top of the first filter screen 3 are blown away, causing them to roll in the sewage; the columnar mouth 16 is provided on the inflation plate 14, and the columnar mouth 16 and the cavity inside the inflation plate 14 are not communicated with each other. After the sewage flows into the first filter screen 3, it flows downward through the columnar mouth 16 to the bottom of the first tank body 1.

[0042] It can be understood that when the sewage enters the first tank body 1, the high-pressure tank body 10 transmits the gas to the inflation plate 14 through the gas pipe 12, and is emitted from the inflation head 15. The outflowing gas impacts upward under the action of pressure, blowing away the solid matter on the top surface of the first filter 3, allowing the liquid sewage to flow downward through the first filter 3 to the bottom of the first tank body 1, and allowing the solid matter on the top surface of the first filter 3 to always be in a floating state, ensuring that the sewage can enter the first filter 3, increasing the flow rate of the sewage, and thereby improving the working efficiency of the first tank body 1.

[0043] In some embodiments, a water inlet 17 is provided in the middle of one side of the second tank body 7, and an opening 18 is provided at the bottom of the first tank body 1. One end of the water inlet 17 is connected to the opening 18 provided at the bottom of the first tank body 1 through a water pipe 8; the other end is connected to the water outlet 19 provided at the top inside the second tank body 7 through a water inlet pipe 41. The water inlet 17 is positioned lower than the water outlet 19, and the opening 18 is positioned higher than the water outlet 19; after the sewage is filtered through the first tank body 1, it flows into the water inlet 17 of the second tank 7 through the water pipe 8 through the opening 18 at the bottom of the first tank body 1. Under the action of atmospheric pressure, the sewage flows into the interior of the second tank body 7 through the water inlet pipe 41.

[0044] It can be understood that the first tank body 1 is higher than the second tank body 7. Under the action of atmospheric pressure, the sewage in the first tank body 1 flows into the inside of the second tank body 7; since the water inlet hole 17 is located lower than the water outlet hole 19, when the sewage flows into the water inlet hole 17, it flows out upward. During the entire movement of the sewage, the fine solid matter moves downward under the action of gravity, further filtering the solid particles in the sewage, reducing the clogging probability of the third filter screen 25 and the fourth filter screen 26, and effectively improving the service life of the third filter screen 25 and the fourth filter screen 26.

[0045] In some embodiments, a spray mechanism is provided on the top of the second tank body, and the spray mechanism includes: a drug inlet pipe 20 and a spray head 23; wherein,

[0046] The drug inlet pipe 20 is fixedly connected to the top of the second tank body 7 and communicates with the internal cavity of the second tank body 7; a plurality of spray heads 23 are evenly arranged on the bottom of the cover plate 22, and the two ends of the spray heads 23 are respectively communicated with the internal cavity of the second tank body 7 and the internal cavity of the cover plate 22; the medicine flows into the internal cavity of the cover plate 22 through the drug inlet pipe 20, and the medicine is evenly sprayed into the internal cavity of the second tank body 7 by the plurality of spray heads 23.

[0047] It can be understood that the medicine can be evenly sprayed on the surface of the sewage under the action of the spraying mechanism, thereby increasing the reaction rate between the sewage and the medicine.

[0048] In some embodiments, the filter assembly includes: a second filter 24, a third filter 25, and a fourth filter 26; the second filter 24 is arranged inside the water inlet pipe 41; a gas transmission device is provided on the top of the third filter 25 and the fourth filter 26, and the third filter 25 and the fourth filter 26 are detachably connected to the support block 2 4 set on the inner wall of the second tank body 7.

[0049] In some embodiments, the gas transmission device includes: a gas outlet plate 27, a gas outlet head 30, and an air pump 31; wherein,

[0050] The air outlet plate 27 is composed of a plurality of strip-shaped cavity components 28, and a plurality of through-hole structures 29 are formed between the plurality of the strip-shaped cavity components 28; the air outlet plates 27 are respectively arranged on the top of the third filter 25 and the fourth filter 26; the sewage flows to the bottom of the second tank body 7 through the through-hole structure 29 under the action of gravity; a plurality of air outlet heads 30 are connected to the top of the strip-shaped cavity component 28; the air pump 31 is connected to the side wall of the second tank body 7, and its air inlet belongs to the outside of the second tank body. The air outlet of the air pump 31 is connected to the air outlet plate 27 through a gas pipeline 33. Under the action of the air pump 31, the gas is transmitted to the air outlet plate 27 and flows into the strip-shaped cavity component 28, and then the gas is discharged by the air outlet head 30.

[0051] It is understandable that oxygen is filled into the second tank body 7 through the air pump 31; the sewage flows downward to the filter plate through the through-hole structure 29, and when oxygen is filled in, it will not affect the flow of sewage into the filter plate.

[0052] In some embodiments, a water receiving trough 34 is provided at the bottom of the third filter screen 25 and the fourth filter screen 26, and a closable water outlet pipe 35 is provided at the bottom of the water receiving trough 34; a first storage chamber 36 is formed between the third filter screen 25 and the top, and the second tank body 7 corresponding to the first storage chamber 36 is connected to the outside of a pH test meter 37 for detecting the pH value of the sewage inside the first storage chamber 36.

[0053] It can be understood that when the sewage enters the first storage chamber 36, it reacts with the medicine and oxygen inside it for a period of time, and then flows to the bottom through the closed water outlet 35 and flows out of the second tank body 7 to obtain sewage filtered by the sewage treatment device; according to the pH test meter 37 set on the outside of the second tank body 7 corresponding to the first storage chamber 36, the pH value in the first storage chamber 36 can be monitored in real time, and the quality of the medicine to be adjusted according to this data.

[0054] In some embodiments, a transparent observation panel 39 is provided on the box door 9; a closable drainage pipe 38 is provided at the bottom of the second tank body 7, and the closable drainage pipe 38 is communicated with the internal cavity of the second tank body 7, and the second tank body 7 discharges the sewage inside the tank body through the closable drainage pipe 38.

[0055] It is understandable that when the filter or a single filter needs to be replaced, the door 9 can be opened for replacement to avoid a single replacement mode; through the transparent observation panel 39 provided on the door 9, the internal working conditions of the second tank body 7 can be viewed in real time, and when abnormal noises or abnormal operations occur, the internal conditions can be known at the first time, and a response plan can be quickly locked, which saves the time of pausing the device for inspection and improves work efficiency.

[0056] In some embodiments, a plurality of retractable brackets 2 are provided at the bottom of the second tank body 7; by adjusting the telescopic length of the retractable brackets 2 at the bottom of the first tank body and the second tank body, the first tank body 1 and the second tank body 7 are placed at different heights.

[0057] It can be understood that when facing different working environments, the first tank body 1 and the second tank body 7 can adjust their own positions through the retractable bracket 2, so as to adapt to a variety of working environments, have good usability, and avoid the time of improving the working environment when facing different working environments.
