Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a sewage treatment device that is easy to maintain. Background Art

[0002] The air flotation machine is a water treatment equipment that produces a large number of fine bubbles in the water by the dissolved air system, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state with a density lower than that of water. The buoyancy principle is used to make it float on the water surface, thereby achieving solid-liquid separation. The advantages of the air flotation machine are that it has the characteristics of low investment, small footprint, high degree of automation, and convenient operation and management. Therefore, it is used in water supply, industrial wastewater and urban sewage treatment.

[0003] When the existing flotation machine is in use, air is introduced into the inside of the flotation machine casing, and tiny bubbles drive the pollutant particles to float up. However, some pollutants may sink to the bottom of the flotation machine casing and accumulate at the bottom of the flotation machine casing, which easily affects the purification effect of the flotation machine. Moreover, the pollutants may settle at the bottom of the flotation machine casing and are inconvenient to clean and maintain, affecting the use of the flotation machine.

[0004] Therefore, there is an urgent need for a sewage treatment device that is easy to maintain to solve the problem that pollutants deposited at the bottom of the flotation machine housing are inconvenient to clean and maintain. Utility Model Content

[0010] Preferably, both sides of the air flotation machine body are connected with sewage outlet pipes.

[0011] The sewage outlet pipe is connected to the external sewage pump, so that the pollutant particles settled at the bottom of the flotation machine body can be easily discharged.

This easy-to-maintain sewage treatment device, when there are more pollutants deposited at the bottom of the flotation machine body, the threaded rod drives the scraper to move, and the scraper will scrape and push the pollutant particles to both sides of the flotation machine body when moving. The sewage outlet pipe is connected to the external sewage pump, and the sewage pump extracts and moves the pollutant particles to the inside of the flotation machine body through the sewage outlet pipe, so that the flotation machine body can self-clean the pollutant particles, which is convenient for automatic maintenance of the flotation machine body.

[0018] 2. This easy-to-maintain sewage treatment device allows air to be fully introduced into the interior of the flotation machine body through multiple sets of connecting pipes and exhaust heads.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] See also Figure 1-4 A sewage treatment device that is easy to maintain includes a flotation machine body 1. The flotation machine body 1 is a pollutant removal device that generates a large number of fine bubbles in the water through a dissolved air system, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water. The buoyancy principle is used to make the air float on the water surface, thereby realizing solid-liquid separation. A pollutant removal mechanism and an air jet mechanism are arranged inside the flotation machine body 1.

[0026] Specifically, the dirt removal mechanism includes a driving motor 111, a threaded rod 112 and a scraper 113. The driving motor 111 is arranged on one side of the flotation machine body 1, one end of the threaded rod 112 is fixedly connected to the output end of the driving motor 111, and the other end of the threaded rod 112 is rotatably connected to the inner side of the flotation machine body 1, the scraper 113 is threadedly connected to the outer surface of the threaded rod 112, the bottom of the scraper 113 is slidably connected to the inner bottom wall of the flotation machine body 1, guide rods 114 are slidably connected on both sides of the scraper 113, both ends of the guide rods 114 are welded to the inner side of the flotation machine body 1, and both sides of the flotation machine body 1 are connected with dirt outlet pipes 115.

[0027] Through the above technical solution, the sewage outlet pipe 115 can be connected to the external sewage pump. When a large amount of pollutants are deposited at the bottom of the flotation machine body 1, the driving motor 111 is started, and the driving motor 111 drives the threaded rod 112 to rotate. When the threaded rod 112 rotates in different directions, it drives the scraper 113 to move. When the guide rod 114 moves, it scrapes and pushes the pollutant particles to move to both sides of the flotation machine body 1. The sewage pump extracts the pollutant particles moved to the inner side of the flotation machine body 1 through the sewage outlet pipe 115, so that the flotation machine body 1 can self-clean the pollutant particles, which is convenient for automatic maintenance of the flotation machine body 1.

[0028] Specifically, the jet mechanism includes a connecting pipe 211, an exhaust head 212 arranged at the bottom of the connecting pipe 211, several groups of connecting pipes 211 are connected to the two ends of the air intake pipe frame 213, the outer surface of the connecting pipe 211 is welded to the plate body on both sides of the air flotation machine body 1, a support plate 214 is welded to the inner side of the air flotation machine body 1, a driving motor 215 is arranged on the top of the support plate 214, a connecting rod 216 is fixedly connected to the output end of the support plate 214, several groups of stirring rods 217 are welded to the outer surface of the connecting rod 216, the other end of the connecting rod 216 is rotatably connected to a fixed plate 218, and both ends of the fixed plate 218 are welded to the inner side of the air flotation machine body 1.

[0029] Through the above technical solution, the air inlet pipe rack 213 is connected to the external air pump. When the air pump introduces air into the connecting pipe 211 through the air inlet pipe rack 213, the air is ejected from the exhaust head 212 to introduce air into the sewage inside the flotation machine body 1. When the driving motor 215 is started, the driving motor 215 drives the stirring rod 217 to rotate through the connecting rod 216. When the stirring rod 217 rotates, the tiny bubbles ejected from the exhaust head 212 are dispersed, so that the tiny bubbles are fully filled in the sewage inside the flotation machine body 1, so that the tiny bubbles can better adhere to the pollutant particles, thereby making the flotation machine body 1 better used.

[0030] During use, when a large amount of pollutants are deposited at the bottom of the flotation machine body 1, the threaded rod 112 drives the scraper 113 to move. When the scraper 113 moves, it scrapes and pushes the pollutant particles to the two sides of the flotation machine body 1. The sewage outlet pipe 115 is connected to an external sewage pump. The sewage pump extracts the pollutant particles moved to the inner side of the flotation machine body 1 through the sewage outlet pipe 115, so that the flotation machine body 1 can self-clean the pollutant particles.
