Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to sewage purification equipment. Background Art

[0002] With the rapid development of industrialization and urbanization around the world, water shortage and water pollution are becoming increasingly serious. As one of the important means to solve these problems, sewage treatment has received widespread attention. Traditional sewage treatment methods usually include physical, chemical and biological methods. These methods can purify and treat sewage to a certain extent, but they face problems such as low treatment efficiency, high energy consumption and large land occupation.

[0003] In view of the shortcomings of traditional sewage treatment methods, sewage treatment technology has been continuously developed and innovated in recent years. Among them, emerging technologies such as membrane technology, biofilm technology, and biosorption technology have gradually been introduced into the field of sewage treatment. These technologies have the advantages of high treatment efficiency, small footprint, and low energy consumption, and have become a research hotspot in the field of sewage treatment.

[0004] In terms of sewage treatment equipment, with the development of intelligent and automated technologies, sewage treatment equipment is also developing in the direction of intelligence and automation. By introducing technologies such as the Internet of Things, big data, and artificial intelligence, sewage treatment equipment can realize functions such as automatic monitoring, intelligent control, and remote operation, which improves the operating stability and treatment effect of the equipment. At the same time, energy conservation and emission reduction is also one of the important directions for the development of sewage treatment equipment. By adopting technical means such as advanced biological treatment processes and efficient energy recovery devices, efficient treatment and resource utilization of wastewater can be achieved while reducing energy consumption.

[0005] However, despite the continuous development and progress of sewage treatment technology and equipment, there are still some challenges. First, sewage contains various complex pollutants, such as heavy metals, refractory organic matter, etc. These pollutants put forward higher requirements for sewage treatment technology. Secondly, the problem of sludge treatment generated during sewage treatment is also one of the problems to be solved in the current sewage treatment field. Sludge contains a large amount of harmful substances, which will cause secondary pollution to the environment if not handled properly. In addition, the energy consumption and operating cost of sewage treatment equipment are also one of the important factors restricting its widespread application. Summary of the invention

[0045] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Example 1: Please refer to Figures 1 to 8 :

[0047] The present invention proposes a sewage purification treatment equipment, comprising a supporting frame 1, a purification treatment box 2, a suction filter cartridge 3, a suction filter air compressor 4, a controller 5, a water treatment truss 6, a water treatment moving frame 7, a scraper 8 and a sludge discharge box 9; the supporting frame 1 is a rectangular parallelepiped frame structure welded from stainless steel, and a rectangular purification treatment box 2 is fixedly welded on the upper end of the supporting frame 1; a vertical suction filter cartridge 3 is butt-jointed to the bottom of one end of the purification treatment box 2, and a sludge discharge box 9 is welded downwardly to the bottom of the other end of the suction purification treatment box 2; a water treatment truss 6 is horizontally arranged at the upper end of the suction purification treatment box 2, and a water treatment moving frame 7 is slidably installed on the water treatment truss 6; a scraper 8 is arranged at the lower end of the water treatment moving frame 7; a suction filter air compressor 4 is fixedly mounted on the side wall of the purification treatment box 2 close to the suction filter cartridge 3, and a controller 5 is fixedly mounted on the side wall of the purification treatment box 2 above the suction filter air compressor 4.

[0048] Wherein, a sewage inlet pipe 201 is provided on the front end side wall of the purification treatment box 2 at a position corresponding to the location of the suction filter cartridge 3, and a solenoid valve is provided on the sewage inlet pipe 201;

[0049] A ceramic filter plate 203 is inlaid at a position corresponding to the top of the suction filter cartridge 3 in the inner cavity of the purification treatment box 2. The ceramic filter plate 203 is located at a position where the upper end of the suction filter cartridge 3 is connected to the purification treatment box 2. An inclined edge block 205 is provided at the side edge of the inner cavity of the purification treatment box 2 at one end of the ceramic filter plate 203. An upwardly convex arc-shaped partition convex body 204 is provided in the inner cavity of the purification treatment box 2 at the other end of the ceramic filter plate 203.

[0050] A sewage level sensor 202 is provided in the inner cavity of the purification treatment box 2 at a position slightly lower than the upper end of the separation convex body 204. The sewage level sensor 202 is interlocked with the electromagnetic valve on the sewage inlet pipe 201. When the sewage in the purification treatment box 2 is higher than the sewage level sensor 202, the opening of the electromagnetic valve on the sewage inlet pipe 201 is reduced, and the water inlet flow rate is reduced;

[0051] Edge clamps 206 are fixedly provided in the inner cavity of the purification treatment box 2 at the front and rear ends of the top of the ceramic filter plate 203, and the two ends of the edge clamps 206 extend and dock to the edge chamfers 205 and the separation protrusions 204 respectively.

[0052] Among them, the lower end of the suction filter cartridge 3 is fixedly connected to a clean water discharge pipe 303, and a solenoid valve is provided on the clean water discharge pipe 303. A suction filter pipe 302 is fixedly connected to the upper middle part of the suction filter cartridge 3. The other end of the suction filter pipe 302 is connected to the suction filter air compressor 4. The end of the suction filter pipe 302 located in the inner cavity of the suction filter cartridge 3 is an oblique downward cut;

[0053] Two dry and wet water level sensors 301 are arranged at intervals on the filter cylinder 3 below the filter tube 302. The upper dry and wet water level sensor 301 is used to detect the upper limit of the water level in the filter cylinder 3, and the lower dry and wet water level sensor 301 is used to detect the lower limit of the water level in the filter cylinder 3.

[0054] Among them, a servo motor 601 is fixedly installed on the side wall of one end of the water treatment truss 6, and a screw rod 603 is rotatably installed at a position corresponding to the servo motor 601 in the water treatment truss 6, and the screw rod 603 is fixedly connected to the rotating shaft of the servo motor 601 through a coupling; the screw rod 603 is rotatably connected to the upper end of the water treatment moving frame 7 through a sleeve block; two parallel sliding rods 602 are fixedly installed in the water treatment truss 6 on the left and right sides of the screw rod 603, and the two sliding rods 602 are respectively connected to the left and right ends of the top of the water treatment moving frame 7 through sliding blocks, and limit switches 604 are respectively provided on the inner side walls of the left and right ends of the water treatment truss 6. When the water treatment moving frame 7 rotates and moves to the extreme positions at both ends with the screw rod 603, the limit switch 604 is squeezed. After the limit switch 604 is triggered, the servo motor 601 reverses.

[0055] Among them, a lifting cylinder 701 is vertically fixed in the middle of the water treatment moving frame 7, and the end of the piston rod of the lifting cylinder 701 is fixedly connected downward to the scraper 8. After the limit switch 604 above the separating convex body 204 is triggered, the piston rod of the lifting cylinder 701 moves downward, and after the limit switch 604 above the sludge discharge box 9 is triggered, the piston rod of the lifting cylinder 701 moves upward.

[0056] Among them, a guide rod 804 is symmetrically arranged on the top of the scraper frame 8, and the upper end of the guide rod 804 passes vertically through the water treatment moving frame 7. The end of the scraper frame 8 away from the guide rod 804 is symmetrically and vertically slid downward and plugged with two buffer rods 801. A scraper 802 is fixedly connected between the lower ends of the two buffer rods 801. The upper ends of the two buffer rods 801 are respectively provided with screw plugs, and a buffer spring 803 is mounted on the buffer rod 801 above the scraper 802.

[0057] The lower end of the scraper 802 is a blade edge facing the side where the sludge discharge box 9 is located. The two ends of the bottom of the scraper 802 are respectively provided with edges 8021 adapted to the edge clamping edge 206. When the lower end of the scraper 802 contacts the ceramic filter plate 203, the edge 8021 slides and fits with the edge clamping edge 206. When the scraper 802 moves to the separating protrusion 204, the edge 8021 is in an open state, and the sewage flows back to the ceramic filter plate 203 through the edge 8021, which can prevent the sludge from carrying too much sewage into the sludge discharge box 9 during the scraping process, thereby improving the treatment and utilization efficiency of the sewage.

[0058] Embodiment 2, based on embodiment 1, the upper end of the sludge discharge box 9 is connected to the bottom plane of the purification treatment box 2 by a connecting port 901, and the lower end of the sludge discharge box 9 is a lower discharge port 902 inclined outward and downward, and the scraped sludge is guided to the sludge discharge box 9 and discharged through the lower discharge port 902.

[0059] The working principle of this embodiment:

[0060] Sewage first flows into the purification treatment box 2 through the sewage inlet pipe 201. In the purification treatment box 2, the sewage will be initially filtered through the ceramic filter plate 203. The ceramic filter plate 203 can effectively intercept solid particles in the sewage to achieve solid-liquid separation. At the same time, the sewage level sensor 202 monitors the water level in the purification treatment box 2 in real time. When the water level reaches or exceeds the set value, the controller 5 will control the solenoid valve on the sewage inlet pipe 201 to reduce the water flow rate to prevent sewage overflow;

[0061] In the filtration stage, the filtration air compressor 4 forms a negative pressure in the filtration cartridge 3 through the filtration pipe 302, extracts the water filtered by the ceramic filter plate 203, and the clean water is then discharged through the clean water discharge pipe 303. At the same time, the dry and wet water level sensor 301 monitors the water level in the filtration cartridge 3 in real time to ensure that it is within a safe range.

[0062] As the sewage is continuously treated, sludge will gradually accumulate on the ceramic filter plate 203. At this time, the servo motor 601 will drive the screw rod 603 to rotate, driving the water treatment moving frame 7 to move horizontally along the slide rod 602. When the water treatment moving frame 7 moves to above the separation convex body 204, the piston rod of the lifting cylinder 701 moves downward, driving the scraper 8 to descend. The scraper 802 on the scraper 8 then moves along the ceramic filter plate 203 to scrape off the sludge trapped thereon. The scraped sludge is guided to the sludge discharge box 9 and discharged through the lower discharge port 902.

[0063] During the entire working process, the controller 5 performs intelligent control based on the feedback signals of various sensors. For example, when the sewage level sensor 202 detects that the water level is too high, the water inlet flow rate will be automatically reduced; when the dry and wet water level sensor 301 detects that the water level in the filter cartridge 3 is abnormal, corresponding safety measures will be taken. In addition, the limit switch 604 can ensure that the water treatment frame 7 can be reversed when it moves to the extreme positions at both ends to prevent collision damage. At the same time, the edge 8021 design of the scraper 802 allows sewage to flow back to the ceramic filter plate 203 during the scraping process, thereby improving the filtration efficiency; the buffer rod 801 and the buffer spring 803 can protect the scraper 802 from damage during movement.
