After being used for a long time, the water in streams, ponds and fountains will contain a large amount of sediment, dead branches, etc., and water treatment is required to remove the sediment, dead branches, and dead leaves.

Water filters in garden lakes mostly use drum filters. For example, Chinese patent CN107261611A discloses a drum filter and method for water filtration. In this solution, a filter screen is installed on the filter cartridge of the drum filter, and the lake or pool water passes through the filter screen from the inside of the filter cartridge, thereby achieving solidification. Due to the effect of liquid separation, solid impurities are left in the filter. As the filter becomes clogged, the filtration effect decreases. Water in the filter cartridge will accumulate, causing the liquid level to rise. When cleaning the filter, the filter will be sprayed from the outside. Filter the water and clean it.

In the above solution, when cleaning the filter screen, the filter cartridge needs to be rotated, and the high liquid level will cause the pressure on the impurities in the filter cartridge to increase, and the adhesion of impurities on the filter screen to increase, making the filter screen more difficult to clean and the cleaning effect to be poor. , which in turn affects the filtration efficiency of the filter. When the liquid level in the filter cylinder is high, the force on the filter will also increase, which can easily damage the filter.

The following describes a garden lake water source circulation system provided by this application with reference to Figures 1-12.

A kind of garden lake water originates from a circulation system and is suitable for sewage treatment, especially suitable for self-circulation filtration of garden lake water sources. It includes a filter box 101. There are water inlet pipes 103 and drainage pipes 104 on both sides of the filter box 101. The lake water passes through The water pump enters the filter box 101 through the water inlet pipe 103. The filter box 101 is provided with a partition. The partition divides the filter box 101 into a water inlet chamber 1011, a filter chamber 1012 and a drainage chamber 1013. The lake water enters the filter box through the water inlet pipe 103. 101, the lake water first enters the water inlet chamber 1011, and a through hole is provided on the partition. The through hole connects the water inlet chamber 1011 and the filter chamber 1012. The lake water enters the filter chamber 1012 through the through hole for filtration.

A filter cylinder 201 is rotated in the filter cavity 1012. A filter screen 202 is installed on the outer circumferential surface of the filter cylinder 201. The axis of the filter cylinder 201 is set horizontally, as shown in Figure 5. When the lake water enters the filter cylinder 201, the lake water flows. After passing through the filter screen 202 of the filter cartridge 201, the filter cartridge 201 rotates around its own axis so that the filter screen 202 absorbs the impurities in the lake water. The partition between the filter cavity 1012 and the drainage cavity 1013 has a through slot close to the bottom of the filter box 101, so The through channel connects the filter chamber 1012 and the drainage chamber 1013. The filtered lake water enters the drainage chamber 1013 and is discharged from the filter box 101 through the drainage pipe 104.

The filter box 101 is provided with a cleaning component, and the cleaning component is located outside the filter cylinder 201. The cleaning component is used to clean the filter 202. As the use time of the filter 202 increases, a large amount of impurities will be adsorbed on the filter 202, causing the filter to The filtration efficiency of 202 decreases. At this time, the impurities on the filter 202 are removed through the cleaning component to keep the filter 202 clean, so that the filtration efficiency of the filter 202 is maintained at the best state.

It should be noted that after the use time of the filter 202 increases, the impurities on the filter 202 gradually increase, and the filter holes on the filter 202 will be blocked to varying degrees, causing the lake water in the filter cartridge 201 to enter the drainage cavity 1013. decreases, but the flow rate of the lake water into the water inlet chamber 1011 through the water inlet pipe 103 does not change, which will cause the lake water level in the filter cartridge 201 to increase. When the water level of the lake water in the filter cartridge 201 is higher, the impurities in the filter cartridge 201 will be filtered. The adhesion strength on the mesh 202 increases, and it is difficult for impurities to escape from the filter mesh 202 , resulting in a decrease in the cleaning effect of the cleaning component on the filter mesh 202 , thereby affecting the filtration efficiency of the filter mesh 202 . It can be understood that the pressure of the lake water in the filter cartridge 201 increases the force exerted on the impurities, so that the adhesion force of the impurities to the filter screen 202 increases. At the same time, the force of the lake water on the filter screen 202 will also increase, which can easily damage the filter screen. 202. Therefore, it is necessary to lower the water level in the filter cartridge 201 to reduce the adhesion of impurities on the filter screen 202 so that the cleaning assembly can better clean the filter screen 202.

A water-absorbing cover 301 is provided in the filter cartridge 201. The water-absorbing cover 301 is shaped like a bowl, and the opening of the water-absorbing cover 301 faces downward. In the initial state, the water-absorbing cover 301 is located below the liquid level of the lake water in the filter cartridge 201, and the water-absorbing cover 301 is filled with lake water. When the lake water level in the filter cartridge 201 is higher than the preset water level value (the preset water level value refers to the water level height when the water level in the filter cartridge 201 is high and affects the cleaning effect of the cleaning component), the water absorbing cover 301 moves in the vertical direction Move upward, but the opening of the water-absorbing cover 301 does not leave the liquid level. The water-absorbing cover 301 raises the lake water inside the water-absorbing cover 301 to above the liquid level under the action of atmospheric pressure, thereby causing the lake water level in the filter cartridge 201 to drop, so as to lower the water level. The adhesion of impurities on the filter 202 enables the cleaning component to better clean the filter 202. After the filter 202 is cleaned, the filter holes of the filter 202 are no longer blocked, and the lake water level in the filter cylinder 201 gradually decreases, absorbing water. The cover 301 also begins to descend and return to the initial position. Whenever the water level in the filter cartridge 201 exceeds the preset water level value, the water-absorbing cover 301 will rise to lower the water level to ensure that the cleaning component maintains a better cleaning effect while avoiding the occurrence of The filter 202 is damaged due to the increased force of the lake water.

Through the arrangement of the water-absorbing cover 301, the liquid level in the filter cartridge 201 is reduced, thereby maintaining a high cleaning efficiency of the cleaning assembly, thereby improving the filtration efficiency of the lake water in the garden from the circulating filtration system, and at the same time avoiding the filter 202 damage, thereby increasing the service life of the filter 202.

In a further embodiment, a water level sensing mechanism is provided in the water inlet chamber 1011, and the water level sensing mechanism is used to sense the height of the water level in the water inlet chamber 1011. When the water level in the water inlet chamber 1011 is higher than the preset water level value, it means that there are more impurities on the filter screen 202, and the filter cartridge of the filter screen 202 is blocked to varying degrees, which causes the lake water flow rate in the filter cartridge 201 to decrease, thereby causing the inlet to The water level in the water chamber 1011 rises. In case of clogging, the water absorbing cover 301 moves upward from below the liquid level, thereby lowering the water level to below the preset water level value, so that the cleaning component can achieve the best cleaning effect and improve the cleaning efficiency of the cleaning component.

If the water level in the water inlet chamber 1011 frequently exceeds the preset water level value, it means that the filter 202 needs to be replaced. It is understandable that the filter 202 still has poor filtering effect after multiple cleanings, and frequent cleaning cannot improve the filter 202 The filtration efficiency indicates that the service life of the filter 202 has reached the limit, and a new filter 202 needs to be replaced to ensure the normal operation of the lake water source circulation filtration system in the garden.

Specifically, the water level sensing mechanism includes a pontoon 401 and a turret 402. The turret 402 is hinged in the filter box 101. The pontoon 401 is installed on the turret 402. The turret 402 can rotate around the hinged position in the filter box 101. The pontoon 401 Floating on the water, the pontoon 401 can sense the water level. When the water level rises, the pontoon 401 drives the turret 402 to rotate around the hinged position. When the water level exceeds the preset water level value, the pontoon 401 reaches the preset height (the preset height refers to the rising water level). reaches the preset water level value), the turret 402 rotates to the preset position (the preset position refers to the position of the turret 402 driven by the turret 402 after the buoy 401 reaches the preset height) and then does not continue to rotate. , at this time, the sensor (not shown in the figure) on the turret 402 sends a signal to cause the water-absorbing cover 301 to start working, thereby lowering the water level.

By arranging a snap assembly at the hinged position of the turret 402, the turret 402 rotates upward to the preset position and no longer rotates upward. The end of the turret 402 away from the hinge center is located above the water-absorbing cover 301 to block the water-absorbing cover 301. break away from the liquid level, thereby ensuring that the opening of the water-absorbing cover 301 does not leave the liquid surface when the water-absorbing cover 301 moves vertically upward, so that the water in the water-absorbing cover 301 can always remain in the water-absorbing cover 301 under the action of atmospheric pressure. As shown in Figure 12, the snap-in assembly includes a one-way ratchet 403 and a blocking block 405. The one-way ratchet 403 is coaxially arranged and fixedly connected to the hinge shaft on the turret 402. The turret 402 is provided with a pawl 404. The pawl 404 is provided with a pawl 404. 404 contacts the ratchet teeth of the one-way ratchet 403 so that the one-way ratchet 403 can only rotate in one direction. That is, as shown in Figure 9, the turret 402 rotates clockwise to drive the one-way ratchet 403 to rotate clockwise, and the turret 402 rotates counterclockwise. When the one-way ratchet 403 is not driven to rotate counterclockwise. When the water level rises, the turret 402 rotates around the hinge axis. Since the pawl 404 meshes with the ratchet teeth of the one-way ratchet 403, the turret 402 drives the one-way ratchet 403 to rotate clockwise. A groove is provided at the hinged position between the inner wall of the filter box 101 and the turret 402, and a blocking block 405 is provided in the groove. The blocking block 405 can move to limit or release the rotation of the one-way ratchet 403.

Specifically, in this embodiment, as shown in FIG. 11 , a compression spring is provided on the left side of the clamping block 405 , the right side of the clamping block 405 is an inclined plane, and a blocking rod is provided on the turret 402 . In the initial state, the block 405 is not in contact with the one-way ratchet 403, but the blocking rod is in contact with the inclined surface of the blocking block 405. The compression spring is in a compressed state under the action of the blocking rod, and when the turret 402 moves smoothly as shown in Figure 9 When the clockwise direction rotates to the preset position, the blocking rod slides on the inclined surface so that the block 405 moves to the right as shown in Figure 11 under the action of the compression spring and then tightly abuts the one-way ratchet 403, so that the one-way ratchet 403 is restricted. Due to the cooperation between the one-way ratchet 403 and the pawl 404, the turret 402 cannot continue to rotate clockwise relative to the one-way ratchet 403. Therefore, the turret 402 will no longer continue to rotate after it rotates to the preset position. Since the turret 402 The end away from the hinge center is located above the water-absorbing cover 301, and the turret 402 shown prevents the opening of the water-absorbing cover 301 from leaving the liquid surface.

In the initial state, the water level is normal, the buoy 401 floats on the water, the turret 402 is in a horizontal state at this time, and the blocking block 405 does not restrict the rotation of the one-way ratchet 403. When the impurities attached to the filter screen 202 increase, the water level in the water inlet chamber 1011 rises and drives the float 401 to rise. The turret 402 rotates around the hinge axis under the action of the float 401. At this time, the one-way ratchet 403 and the turret 402 Rotate synchronously, when the water level rises to the preset water level value, the blocking block 405 tightly abuts the one-way ratchet 403 under the action of the baffle slope on the turret 402 and the action of the compression spring. The blocking block 405 moves the one-way ratchet wheel 403 is fixed, the turret 402 cannot rotate in the clockwise direction as shown in Figure 9, but the turret 402 can rotate counterclockwise. At this time, the sensor on the turret 402 sends a signal to cause the water-absorbing cover 301 to move upward. At this time, the turret 402 can prevent the opening of the water-absorbing cover 301 from leaving the liquid surface to ensure that the water in the water-absorbing cover 301 does not escape under the action of atmospheric pressure. Since the position of the water-absorbing cover 301 rises, the liquid level in the water inlet chamber 1011 drops. After the liquid level in the water inlet chamber 1011 drops, the liquid level inside the filter cartridge 201 also drops, so that the cleaning nozzle 206 has a better cleaning effect when cleaning the filter screen 202, thereby increasing the filtration efficiency of the filter screen 202.

Specifically, the cleaning assembly includes a cleaning pump 207 and a cleaning nozzle 206. The cleaning nozzle 206 is arranged in the filter box 101. Specifically, the cleaning nozzle 206 is located above the filter cylinder 201, and the cleaning nozzle 206 sprays water along the radial direction of the filter cylinder 201, so as to Maximize the impact of the water flow on impurities and ensure that the impurities can be washed away by the water flow. The cleaning pump 207 is connected to the cleaning nozzle 206, and the cleaning pump 207 provides pressure for the cleaning nozzle 206, so that the pressure of water sprayed by the cleaning nozzle 206 is greater, and the cleaning intensity of the cleaning nozzle 206 is improved.

It should be noted that the cleaning component is not limited to the above structure, but can also be other structures, such as a high-pressure air pump. The nozzle of the high-pressure air pump is arranged above the filter cartridge 201, and the gas ejected by the nozzle is also blown along the radial direction of the filter cartridge 201. The filter cartridge 201 makes it easier to blow off impurities from the filter screen 202. Of course, other structures capable of cleaning the filter 202 are also possible, which will not be described in detail here.

In a further embodiment, a drain tank 204 is provided in the filter cartridge 201. The drain tank 204 and the filter drum 201 do not rotate synchronously. The drain tank 204 is fixed on the filter box 101, and the impurities washed away by the cleaning nozzle 206 fall into the drain tank. In the tank 204, a sewage pipe 205 is also connected to the filter box 101. The sewage pipe 205 is connected with the sewage tank 204. The impurities collected in the sewage tank 204 are discharged from the filter box 101 through the sewage pipe 205.

In a further embodiment, the garden lake water source circulation filtration system also includes a first driving mechanism and a second driving mechanism. The first driving mechanism is used to drive the filter cylinder 201 to rotate, and the second driving mechanism is used to drive the water absorbing cover 301 to rotate. Move vertically.

Specifically, in this embodiment, the first driving mechanism includes a first motor 203 and a ring gear. The ring gear is fixedly arranged on the outer peripheral surface of the filter cartridge 201. The first motor 203 is located in the filter box 101. The rotating shaft of the first motor 203 Engaged with the ring gear, the first motor 203 is energized and rotates to drive the ring gear to rotate, thereby driving the filter cartridge 201 to rotate around its own axis. It should be noted that the rotation speed of the motor is adjustable, thereby adjusting the rotation speed of the filter cartridge 201 to adjust the filter cartridge. 201 filter rate.

Of course, the first driving mechanism is not limited to the above structure, and can also be driven by a belt. For example, a belt is wound around the outer circumference of the filter cylinder 201, and the first motor 203 drives the belt to rotate to drive the filter cylinder 201 to rotate. It can also be Other institutions are not listed here.

Specifically, in this embodiment, the second driving mechanism includes a second motor 303 and a traction rope 302. Vertical grooves are provided on the partitions on both sides of the filter chamber 1012. Sliders are provided at both ends of the water-absorbing cover 301. The sliders Located in the vertical groove, one end of the traction rope 302 is connected to the slider to move the water-absorbing cover 301. The other end of the traction rope 302 is connected to a traction block 305. A roller 304 is rotated in the filter box 101. The traction rope 302 is wound around On the roller 304, the second motor 303 drives the roller 304 to rotate after being powered on. There is friction between the traction rope 302 and the roller 304. When the roller 304 rotates, it can drive the traction rope 302, and the traction rope 302 then pulls up the water-absorbing cover 301 to absorb water. The cover 301 can move upward in the vertical direction.

The turret 402 prevents the opening of the water-absorbing cover 301 from leaving the liquid level. Specifically, the end of the turret 402 away from the hinge center is located above the slider of the water-absorbing cover 301. When the water-absorbing cover 301 rises, the slide of the turret 402 and the water-absorbing cover 301 As shown in Figure 4 and Figure 6, one end of the turret 402 is located on the slider of the water-absorbing cover 301 to limit the upward movement distance of the water-absorbing cover 301 to ensure that the water-absorbing cover 301 does not leave the liquid surface. When the water-absorbing cover 301 rises to the highest position limited by the turret 402 under the traction of the traction rope 302 (the highest position refers to the highest position where the water-absorbing cover 301 does not break away from the liquid level when moving upward in the vertical direction), due to the rotation Due to the limitation of the frame 402, the traction rope 302 will slip on the roller 304, the roller 304 keeps rotating, and the relative movement between the traction rope 302 and the roller 304 makes the pulling force of the traction rope 302 on the water-absorbent cover 301 remain unchanged, that is, at this time, the traction rope The pulling force of 302 on the water-absorbing cover 301 is balanced by the gravity of the water in the water-absorbing cover 301 and the supporting force of the turret 402 on the water-absorbing cover 301 . When the liquid level in the filter cartridge 201 drops, the height of the water in the water-absorbing cover 301 from the liquid level increases, which is equivalent to an increase in the water above the liquid level in the water-absorbing cover 301, so that the force exerted by the water-absorbing cover 301 on the traction rope 302 increases. , the liquid level drops, and one end of the turret 402 is located on the slider of the water-absorbing cover 301, so the buoy 401 on the turret 402 is suspended, and the buoy 401 does not receive buoyancy, so that the water-absorbing cover 301 is affected by the turret 402 and the buoy 401. Gravity acts, and the pulling force of the traction rope 302 remains unchanged, so the pulling force is not enough to overcome the above force and cause the water-absorbing cover 301 to move downward. When the water-absorbing cover 301 moves downward, the amount of water above the liquid level in the water-absorbing cover 301 decreases. When , the force exerted by the water-absorbing cover 301 on the traction rope 302 begins to decrease, and the buoy 401 does not exert any force on the water-absorbing cover 301 when floating on the water. At this time, the pulling force of the traction rope 302 is greater than the pulling force of the water-absorbing cover 301 on the traction rope 302 , the water-absorbing cover 301 moves downward for a certain distance and then is pulled up by the traction rope 302. After being pulled up, it is continued to be restricted by the turret 402. When the water level drops, the float 401 descends to drive the turret 402 to rotate, and the one-way ratchet 403 on the turret 402 is restricted by the block 405 from rotating, so the turret 402 can only rotate in one direction to limit the rise of the water-absorbing cover 301. The cycle is repeated sequentially, so that the entire water-absorbing cover 301 moves downward. When the water level returns to normal, the second motor 303 rotates in reverse direction to immerse the water-absorbing cover 301 in the water again.

It should be noted that the second driving mechanism is not limited to the above structure, and may also be a friction torque limiter set on the rotating shaft of the second motor 303, and one end of the traction rope 302 is connected to the friction torque limiter. The rotation of the second motor 303 drives the friction torque limiter, and the friction torque limiter drives the traction rope 302 to pull up the water-absorbing cover 301. When the water-absorbing cover 301 moves to the preset position and the friction torque limiter reaches the preset torque, the friction torque limiter The material begins to slip, causing the traction rope 302 to provide a constant pulling force on the water-absorbent cover 301.

In a further embodiment, the filter box 101 is provided with an end cover 102 that is snap-fitted. The snap-fit arrangement makes it easy to disassemble and install the end cover 102 and to facilitate the replacement of the filter screen 202.

The specific working process of a garden lake water source circulation filtration system provided by this application will be described below in conjunction with the above embodiments:

The lake water in the garden is pumped into the filter box 101 through a water pump, and the impurities in the lake water are filtered by the filter cartridge 201 in the filter box 101, and then discharged from the filter box 101 through the drainage pipe 104 and returned to the inner lake, forming a cycle.

When the lake water enters the filter box 101, it first passes through the water inlet chamber 1011, then enters the filter chamber 1012 for filtration, and is finally discharged through the drainage chamber 1013. In the filter cavity 1012, the filter cartridge 201 is driven by the first motor 203 to rotate around its own axis to filter the lake water.

Under normal circumstances, the water inlet volume of the water inlet pipe 103 is consistent with the drainage volume of the drainage pipe 104, and the water level in the filter cartridge 201 remains unchanged. Only when the impurities on the filter screen 202 increase, resulting in a decrease in filtration efficiency, the water level in the filter cartridge 201 It will gradually increase due to the blockage of the filter 202. At this time, the cleaning pump 207 is started, the cleaning nozzle 206 cleans the filter 202, and the sewage tank 204 collects the impurities sprayed by the nozzle and discharges them through the sewage pipe 205.

When the water level is high, the force of the lake water on the impurities in the filter cylinder 201 increases, which increases the adhesion of the impurities on the filter screen 202, resulting in poor cleaning effect of the cleaning nozzle 206. Therefore, when the water level rises to the preset water level When the value is reached, the water absorbing cover 301 rises to lower the water level to improve the cleaning effect of the cleaning nozzle 206 .

Specifically, the buoy 401 is located on the water surface. As the water level rises, the buoy 401 also rises to drive the turret 402 to rotate around the hinge axis. When the height of the buoy 401 is higher than the preset water level value, the turret 402 rotates to the preset position. , at this time, the block 405 fixes the one-way ratchet 403 on the turret 402, and the turret 402 cannot rotate upward. At this time, the second motor 303 starts, and the rotation of the second motor 303 drives the water-absorbing cover 301 to move upward, and the water-absorbing cover 301 moves upward. After reaching the preset position, it is limited by the turret 402 and the water-absorbing cover 301 cannot continue to move. The rise of the water-absorbing cover 301 drives the water in the water-absorbing cover 301 to rise above the liquid level. The water level in the filter cartridge 201 decreases, and the force of the lake water on the impurities is reduced. The cleaning nozzle 206 can better clean the impurities. On the filter screen 202 The impurities are reduced and the filtration efficiency is increased, so that the water level in the filter cartridge 201 gradually returns to the normal state, that is, the water level gradually decreases.

Before the water level drops, the pulling force of the traction rope 302 on the second motor 303 and the limiting effect of the turret 402 balance the force on the water-absorbing cover 301. The supporting force and the gravity of the water in the water-absorbent cover 301 are balanced. When the water level drops, the height of the water-absorbing cover 301 from the liquid surface increases, so that the force of the water in the water-absorbing cover 301 on the water-absorbing cover 301 increases, and the acting force of the buoy 401 and the turret 402 on the water-absorbing cover 301 increases, thereby causing the water absorption The force on the cover 301 is unbalanced, and the water-absorbing cover 301 moves downward. Since the buoy 401 floats on the water surface, when the water level drops, the buoy 401 drives the turret 402 to rotate downward. When the water-absorbing cover 301 moves downward, the height of the water-absorbing cover 301 from the liquid level decreases, and the force exerted by the water in the water-absorbing cover 301 on the water-absorbing cover 301 decreases. The traction rope 302 pulls the water-absorbing cover 301 to move upward again, but at this time the water absorption The cover 301 moves upward and is restricted by the turret 402. Therefore, the water-absorbing cover 301 fluctuates up and down on the liquid surface but drops as the water level decreases. When the turret 402 returns to the horizontal state, the water-absorbing cover 301 is fully immersed again. In the lake water, it is below the liquid level until the water level rises to the preset water level value again, and then the above process is cycled.

It should be noted that when the water level exceeds the preset water level value more frequently, it means that the filter 202 needs to be replaced. Please replace the filter 202 with a new one to ensure the normal operation of the lake water source circulation filtration system in the garden.
