The embodiment of the application provides a water treatment facilities, the during operation begins, and the waste water that the inlet tube flows gets into intake chamber once, first flexible motor drive first filter screen is located intake chamber's cross section to filter waste water. When the flow rate detected by the flowmeter is less than a first threshold value, the condition that the floating objects such as hair and the like accumulated on the first filter screen are more, the water level is increased due to the fact that water is not communicated smoothly, and resistance is formed. The water velocity of the inlet pipe is reduced.

Referring to fig. 1 and 2, an embodiment of the present invention provides a water treatment apparatus 10, including a primary water inlet tank 100, a first filter 130, a second filter 140, a first telescopic motor 150, a second telescopic motor 160, a first water pipe 170, a secondary water inlet tank 180, a first water level detector 220, a second water level detector 230, and a controller. The top of the intake pool is provided with an intake pipe 110, and the intake pipe 110 is provided with a flowmeter 120. The first filter 130 and the second filter 140 are movably disposed on the sidewall of the primary water inlet tank 100 at intervals along the vertical direction. There may be two passages in the side wall of the intake pool for the first filter 130 and the second filter 140 to enter and exit from the side wall of the primary intake pool 100. When the first filter 130 or the second filter 140 is protruded from the sidewall of the primary inlet tank 100, the wastewater for leather production flowing out of the inlet pipe 110 can be filtered. The first and second stretching motors 150 and 160 are respectively connected to the first and second filters 130 and 140. The first extension motor 150 is used for driving the first filter 130 to move along the horizontal direction, and the second extension motor 160 is used for driving the second filter 140 to move along the horizontal direction.
The first and second stretching motors 150 and 160 may control the first and second filters 130 and 140 to extend or retract into the side wall of the primary water inlet tank 100. The first and second telescopic motors 150 and 160 may be provided at a side wall of the primary intake reservoir 100. The first water pipe 170 is disposed between the bottom of the intake tank and the second filter 140. The water inlet of the first water pipe 170 is funnel-shaped and receives water filtered by the first filter 130 or the second filter 140, and the water outlet of the first water pipe 170 is disposed near the bottom of the water inlet tank. The secondary water inlet pool 180 is arranged beside the primary water inlet pool 100, the side wall of the bottom of the primary water inlet pool 100 is communicated with the bottom of the secondary water inlet pool 180 through a first pipeline 190, and the first pipeline 190 is provided with a water suction pump 210 for pumping water from the bottom of the primary water inlet pool 100 to the secondary water inlet pool 180. The first water level detector 220 and the second water level detector 230 are sequentially disposed on the sidewall of the bottom of the primary water inlet tank 100, and the height of the first water level detector 220 is higher than that of the second water level detector 230. The controller is connected to the first water level detector 220, the second water level detector 230, the water pump 210, the flow meter 120, the first telescopic motor 150, and the second telescopic motor 160.
When the water filter starts to work, the wastewater flowing out of the water inlet pipe 110 enters the primary water inlet tank 100, and the first telescopic motor 150 drives the first filter screen 130 to be located on the cross section of the primary water inlet tank 100 so as to filter the wastewater. When the flow rate detected by the flow meter 120 is less than the first threshold, it indicates that there are more floating objects such as hair accumulated on the first filter 130, which causes a water level to rise due to poor water flow, and forms resistance. The water velocity of the inlet pipe 110 is reduced. When the first threshold is decreased, it means that the hair or the like on the first filter 130 is too much at this time, and the next filtering is affected. At this time, the controller controls the first extension motor 150 to make the first filter 130 retract to the side wall of the primary water inlet tank 100. The retracted first filter 130 may then be cleaned. It will be appreciated that the side walls of the primary reservoir may be provided with a service cleaning volume into which the first filter 130 can be retracted. Maintenance personnel may enter the clean-up space from outside the primary basin to filter the first filter 130.
And at the same time, the second telescopic motor 160 is controlled to control the second filter 140 to extend out from the side wall of the primary water inlet tank 100 to filter water. There is no hair or the like on the second filter 140 to block the water flow, so that the water flow can be restored to normal and the filtering of the waste water is started. The first filter 130 and the second filter 140 are alternately operated to secure a filtering effect and a water flow rate, thereby providing an operation efficiency.
The height of the first water level detector 220 is higher than that of the second water level detector 230, and it can be understood that, in the process of rising the wastewater level, the flow rate of water is reduced due to gravity and resistance of the water flooding the water outlet of the first water pipe 170, and the bottom space of the primary water tank is enlarged, so that floating objects such as hair in the wastewater float for a sufficient time. When the first water level detector 220 detects the water level signal, it indicates that the water flowing out from the water outlet of the first water pipe 170 rises to the height of the first water level detector 220, and the time is enough for the floating objects such as hair to gradually float up to the upstream of the water surface. The water pump 210 and the first channel are arranged at the bottom of the primary water inlet, at this time, the controller controls the water pump to pump water, and the hair at the bottom of the primary water inlet tank 100 is few, so that the floating amount of the hair and the like contained in the water pumped to the secondary water inlet tank 180 by the first channel can be greatly reduced. When the second water level detector 230 cannot detect the water level signal, which indicates that the water level has dropped more, the water may be pumped away by the hair on the water surface, and therefore the water pumping may be stopped to wait for the water level to rise further.
In one embodiment, the water treatment apparatus 10 further comprises a second water pipe 250 vertically disposed in the secondary water inlet tank 180. The water inlet of the second water pipe 250 is communicated with the water outlet of the first pipeline 190. Therefore, the waste water flowing out of the outlet of the first pipe 190 will rise along the second water passing pipe 250. The water outlet of the second water conduit 250 is trumpet-shaped. The flow rate of the wastewater rising through the second water passage 250 is already low at this time, and therefore, the wastewater flows out of the outlet of the second water passage 250 in an overflow state rather than in a spray state. The wastewater flows down along the outer wall of the outlet of the second draft tube 250 by gravity. The outer wall of the water outlet of the second water pipe 250 is provided with a plurality of needle-shaped protrusions 252. The density of the needle-like projections 252 may be dense. Thus, fine hair that has not been removed in the waste water can be further filtered.
In one embodiment, the water treatment apparatus 10 further includes a water return sleeve 260. The water return sleeve 260 is sleeved outside the second water through pipe 250. Namely, the water return sleeve 260 and the second water passage 250 are coaxially disposed. A first filter plate 270 is horizontally arranged between the water return sleeve 260 and the second water through pipe 250, and the first filter plate 270 is sleeved on the water outlet of the second water through pipe 250 and used for filtering water passing through the needle-shaped protrusion 252. That is, the water filtered through the needle-shaped protrusions 252 is blocked by the first filter plate 270 from flowing all around along the first filter plate 270. At this time, the water flow speed is low, so the water level height when the first filter plate 270 horizontally flows is low, the first filter plate 270 filters more finely, and the effect is better. The filtered water is left to the bottom of the secondary water inlet tank 180 from the position between the water return sleeve 260 and the second water communication pipe 250.
In one embodiment, the first filter plate 270 is provided with a plurality of filter walls 272 at intervals in the water flow direction for filtering the wastewater horizontally flowing in the first filter plate 270. The filter wall 272 may be a vertical mesh screen or the like.
In one embodiment, a second filter plate 280 is horizontally disposed between the water return sleeve 260 and the second water passage pipe 250. The second filter plates 280 filter water flowing in a vertical direction after being filtered by the first filter plates 270. The water flowing from the edge of the first filter plate 270 away from the second water passing tube 250 falls down to the second filter plate 280 in a vertical direction. The mesh density of the second filter plate 280 may be smaller than that of the first filter plate 270. It will be appreciated that floaters such as hair may have different weights at different locations on their own. The attitude of the hair in the water flow in different directions is therefore also different. The filtering efficiency is improved by filtering the wastewater in the horizontal direction through the first filter plate 270 and filtering the wastewater in the vertical direction through the second filter plate 280, and filtering the floaters such as hair in different postures.
In one embodiment, the water inlet device further comprises a third filter plate 290 horizontally sleeved on the outlet of the second water inlet pipe 250, and the water outlet 292 of the secondary water inlet tank 180 is arranged on the side wall of the third filter plate 290 far away from the bottom of the secondary water inlet tank 180. That is, after the wastewater flows out from the outlet of the second water pipe 250, the wastewater is further filtered by the third filter plate 290 during the process of rising the water surface, thereby ensuring the filtering effect. The wastewater filtered by the third filter plate 290 flows out through the drain 292 and then goes to the next water treatment process.
The foregoing is only a preferred embodiment of the present application and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the present application and these modifications should also be considered as the protection scope of the present application.
