Description

Technical Field

[0001] The utility model relates to the technical field of tap water production, in particular to a single-valve linkage speed-controlled siphon system for a filtering pool. Background Art

[0002] The filter tank is an important process in the field of water treatment technology. The filtration process includes two stages: filtration and backwashing. In the filtration stage, the water that has been treated by the previous process will be retained between the filter media when passing through the filter media. The filtered and purified water will be collected by the water collection pipe and enter the clear water tank or the next process. It is the last process in the water treatment process to reduce the turbidity of the water body. The backwashing stage is to use the water distribution system to reversely wash the particle impurities deposited and retained in the filter media with the filtered and purified water, and then discharge them through the drain pipe, thereby restoring the good filtration effect of the filter media and ensuring the efficient operation of the filter tank.

[0003] The siphon filter is a form of rapid filter that uses a siphon tube to replace the water inlet and drain valves. It does not require large valves for control, and can start and stop the water inlet and drain by driving the vacuum environment of the siphon tube through a vacuum pump or hydraulics. The vacuum environment of the siphon tube is formed slowly when it is controlled by hydraulics alone, and air leakage in hidden places will prolong the time it takes to form a vacuum environment. Although the vacuum pump control system can solve this problem, it requires an additional pneumatic system to be built. They all have a common feature, that is, more valves are required for the control of a single filter tank. However, a group of siphon filters consists of at least 6-8 filter tanks, and as many as 16-22. Therefore, a group of siphon filters requires the operation of more valves, the steps are more complicated, and the overall time required is longer. In addition, the siphon tube group is larger in size and more difficult to replace, which also brings certain difficulties to automatic control and later maintenance. Utility Model Content

DETAILED DESCRIPTION

[0032] like Figure 1-2 A single-valve linkage speed-controlled siphon system for a filter pool includes a first siphon group 1 and a second siphon group 8. The filter pool 4 includes a filter operation layer 401 and a backwash layer 402. Water seal bases 3 are provided on the inner and outer sides of the filter pool 4, respectively. The first siphon group 1 is straddled on the filter pool 4, one side of the first siphon group 1 is located in the backwash layer 402, and the other side of the first siphon group 1 is arranged in the water seal base 3 on the outer side of the filter pool 4. The second siphon group 8 is straddled between the water seal base 3 on the inner side of the filter pool 4 and the water inlet channel 5. The first siphon group 1 is used to backwash and discharge the sewage in the backwash layer 402, and the second siphon group 8 is used to replenish water to the filter operation layer 401. Air inlet pipe groups 7 are provided on the tops of the first siphon group 1 and the second siphon group 8, respectively, and the two air inlet pipe groups 7 are connected by a single-valve speed-control component 2. An effective space of not less than 5 cm is left between the bottom openings of the first siphon tube group 1 and the second siphon tube group 8 and the bottoms of the water seal base 3, the filter pool 4 and the water inlet channel 5, respectively, so as to ensure normal water absorption and water intake, wherein the opening on one side connected to the water seal base 3 is always immersed in water, and a sealing effect is formed on the opening here by water. The first siphon tube group 1 and the second siphon tube group 8 cooperate with each other to realize the control of the entry and exit renewal of water in the filter pool 4.

[0033] In the preferred solution, the single valve speed control assembly 2 includes a high-pressure water control valve 201, a high-pressure water inlet pipe 202 is provided on one side of the high-pressure water control valve 201, and two speed drain pipes 204 are provided on the other side of the high-pressure water control valve 201. The two speed drain pipes 204 are arranged directly opposite to the filter pool 4. The bottom of the speed drain pipe 204 close to the second siphon pipe group 8 is located in the filter operation layer 401, and the bottom of the speed drain pipe 204 close to the first siphon pipe group 1 is higher than the highest water storage level of the filter pool 4. The air inlet pipe group 7 includes an exhaust pipe 701 and a ball valve 702 arranged on the exhaust pipe 701. A water ejector 203 is arranged on the speed drain pipe 204, and the water ejector 203 is connected to the exhaust pipe 701 through the first air intake pipe 205. The water ejector 203 can increase the speed and pressure of the water flow, thereby ensuring that the two siphon systems work efficiently and save more time. When high-pressure water passes through the water ejector 203, negative pressure is generated inside, so that the air inside the siphon tube group is sucked out by the water ejector suction pipe 205 and discharged with the water flow. The greater the water pressure of the high-pressure water, the faster the air suction speed, and the shorter the time it takes for the siphon tube group to form an internal vacuum environment. The speed control device 2 can quickly control the siphon tube group to enter the water absorption state.

[0034] In the preferred embodiment, a gravity exhaust assembly 6 is also provided in the water inlet channel 5, and the gravity exhaust assembly 6 includes a drain outlet 602, and a gravity exhaust control valve 601 is provided on one side of the drain outlet 602. The drain outlet 602 is connected to the air inlet pipe group 7 on the second siphon group 8 through the second air intake pipe 603, and the bottom of the gravity exhaust control valve 601 is arranged opposite to the filter tank 4.

[0035] The gravity exhaust assembly 6 is installed in the water inlet channel 5 of the filter tank. The main body is located at the drain outlet 602. Therefore, the water inlet of the main body is vertically inserted into the water of the water inlet channel 5. The gravity drain outlet 602 at the other end passes through the water inlet channel 5 and vertically leads to the filter tank 4. At the outlet end, a position not less than 10 cm away from the top of the gravity exhaust assembly 6 is installed. The suction pipe 603 smaller than the diameter of the main body is connected to the exhaust pipe 701. During production, the water level in the channel rises and submerges the top of the gravity exhaust device 6, so that sufficient water enters the device from the pipe mouth to fill the entire pipe body, and finally drains out through gravity. The water inlet 602 flows into the filter pool. In the working state, the gravity exhaust control valve is in the open state. When the water inlet channel 5 is filled with water, the water enters the component and flows from the normal pressure drain port 602 to the filter pool 4 by gravity. After the water level of the water inlet channel 5 exceeds the top of the gravity exhaust component, the water fills the pipe body to form a negative pressure in the gravity exhaust component. The air in the second siphon group 8 is sucked out through the suction pipe 603. After the second siphon group 8 enters a vacuum environment, the water absorption function is started. The water is pumped from the water inlet channel 5 to the water seal base 3 through the second siphon group 8 and then flows into the filter pool 4. When the filter pool 4 stops running or the water volume is insufficient, no water in the water inlet channel 5 enters the gravity exhaust component 6, and air enters the second siphon group 8 from the normal pressure drain port 602 to stop absorbing water. When maintenance is required, the gravity exhaust control valve 601 is closed to block the water flow, and air enters the second siphon group 8 from the normal pressure drain port 602 to stop absorbing water. Except for maintenance, the gravity exhaust assembly 6 is operated automatically by hydraulic power throughout the entire process and does not require human operation.

[0036] like Figure 3-7 In the preferred solution, a bearing platform 12 is provided in the water seal base 3, and a support rod 11 is provided at the bottom of the first siphon tube group 1 and the second siphon tube group 8, and the support rod 11 is clamped with the bearing platform 12, and the bearing platform 12 and the support rod 11 are connected to form a water flow channel. With this structure, the overall installation and disassembly are convenient, and it is convenient for later maintenance.

[0037] In the preferred solution, the first siphon tube group 1 and the second siphon tube group 8 have the same structure, which includes a curved tube 9, with straight tubes 10 arranged in parallel on both sides of the curved tube 9, the curved tube 9 is connected to the straight tube 10 through a nut 14 and a screw 15, and a support rod 11 is arranged at the lower side of the straight tube 10. This structure makes it easy to manufacture, has higher interchangeability, and can more flexibly cope with changes in the straight tube 10 or the curved tube 9, thereby ensuring that the use cost is reduced and the replacement is convenient.

[0038] like Figure 9-11In the preferred solution, two first sealing plates 16 are symmetrically arranged at the lower part of the curved pipe 9, and the second sealing plate 17 and the first sealing plate 16 are respectively arranged at the upper side and the lower side of the straight pipe 10, and the middle parts of the first sealing plate 16 and the second sealing plate 17 are respectively provided with a first sinking groove 1603 and a second sinking groove 1703, and the sealing ring 13 is located in the first sinking groove 1603 and the second sinking groove 1703, and the first sealing plate 16 and the second sealing plate 17 are connected to the screw 15 through the nut 14. With this structure, the first sealing plate 16 and the second sealing plate 17 cooperate with each other, and with the cooperation of the sealing ring 13, a stable sealing retaining wall can be formed between the two, thereby ensuring the air tightness inside the siphon tank group.

[0039] In the preferred solution, the first sealing plate 16 and the second sealing plate 17 respectively include a first concave-convex surface 1601 and a second concave-convex surface 1701, the first concave-convex surface 1601 and the second concave-convex surface 1701 are fitted together, the middle of the first concave-convex surface 1601 and the second concave-convex surface 1701 are respectively provided with a first alignment platform 1602 and a second alignment platform 1702, and the first sink groove 1603 and the second sink groove 1703 are respectively provided on the first alignment platform 1602 and the second alignment platform 1702. With this structure, the cross-sections of the first sealing plate 1601 and the second concave-convex surface 1701 are wavy, and the first sealing plate 1601 and the second concave-convex surface 1701 cooperate with each other, which greatly increases the contact area between the two, and the overall sealing effect is better.

[0040] like Figure 8 In the preferred solution, the load-bearing platform 12 includes a bottom plate 1201 and a fixing block 1202. The upper part of the bottom plate 1201 is provided with a plurality of countersunk holes 1204 along the circumferential direction. The countersunk holes 1204 are provided with slideways 1205. The support rod 11 includes a round rod 1101 and a sensing column 1102. The outer diameter of the sensing column 1102 is equal to the inner diameter of the countersunk hole 1204. The outer side of the load-bearing platform 12 is connected with a locking assembly 18 through a screw 15. The locking assembly 18 is used to lock the sensing column 1102. With this structure, the overall installation and maintenance are convenient, and the overall removal or putting down can be completed without external tools when in use.

[0041] like Figure 12-14In the preferred embodiment, the locking assembly 18 includes a connecting plate 1801 and a locking head 1802, the connecting plate 1801 is connected to the fixing block 1202 by means of screws 15, a guide rod 1803 is provided on one side of the locking head 1802, the guide rod 1803 is penetrated by the locking head 1802, a spring 1804 is sleeved on the guide rod 1803, the guide rod 1803 is connected to the connecting plate 1801 by means of a nut 14, a first inclined surface 1103 and a second inclined surface 1104 are respectively provided on the upper and lower sides of the sensing column 1102, a third inclined surface 1807 and a fourth inclined surface 1808 are respectively provided on the upper and lower sides of the locking head 1802, the second inclined surface 1104 cooperates with the third inclined surface 1807, and the first inclined surface 1103 cooperates with the fourth inclined surface 1808. With this structure, when the sensing column 1102 moves downward and enters the counterbore 1204, the second inclined surface 1104 and the third inclined surface 1807 cooperate with each other, the sensing column 1102 squeezes the lock head 1802, and then the lock head 1802 gives way, and the sensing column 1102 continues to move downward. When the bottom surface fits into the counterbore 1204, the lock head 1802 is reset under the action of the spring 1804, and the fourth inclined surface 1807 fits on the first inclined surface 1103. When the support rod 11 needs to be taken out, the multiple support columns 11 and the bearing platform 12 cooperate with each other to ensure that the bent pipe 9 and The straight pipe 10 is stable. Since the bent pipe 9 and the straight pipe 10 have a large dead weight, they can be stably fixed on the load-bearing platform 12. When they need to be taken out, the connection between the bent pipe 9 and the straight pipe 10 can be released in different positions and sections. At the same time, a wooden pole can be used to pass through the lower part of the bent pipe 9 and then support the bent pipe to remove the straight pipe 10 on the load-bearing platform 12. When the lowest straight pipe 10 is removed, the staff can lift it up. At this time, the first inclined surface 1103 pushes the third inclined surface 1807 to compress the lock 1802 to make way until it is taken out. The design is clever and easy to use.

[0042] In the preferred solution, the two round rods 1101 on the same side are connected by a synchronous plate 1105, a screw 1106 is provided on the top of the synchronous plate 1105, and the screw 1106 is connected to the straight tube 10 through a nut 14, and the fifth inclined surface 1203 is provided on both sides of the load-bearing platform 12, a first through hole 1805 is provided in the middle of the connecting plate 1801, and second through holes 1806 are provided on both sides of the first through hole 1805, and threaded holes 1206 are provided on both sides of the slideway 1205, and screws 15 are inserted into the second through hole 1806 and the threaded hole 1206, and the guide rod 1803 is inserted into the first through hole 1805.

[0043] Working principle:

[0044] When the filter pool 4 is working normally, the interior of the second siphon group 8, which is responsible for the water inlet function, continues to maintain a vacuum environment under the action of the gravity exhaust component 6, so that the water to be treated in the filter pool inlet channel 5 continuously enters the filter pool 4. When the filter pool 4 needs to be backwashed when the operation cycle is reached, it is only necessary to open the high-pressure water control valve 201 to allow high-pressure water to enter the single-valve speed control component 2 of the first siphon group 1, which is responsible for the drainage function. When the high-pressure water passes through the speed control device 2, it takes out the air in the first siphon group 1, so that a vacuum environment is quickly formed inside the first siphon group 1 and starts to absorb water. The first siphon group 1 absorbs a large amount of water and backwashing wastewater in the filter pool 4, so that the liquid level of the filter pool 4 is in the filter pool backwashing interval 402 and continues to maintain the backwashing state. At this time, the outlet of the speed drain pipe 204 of the single-valve speed control component 2 of the second siphon group 8, which is responsible for the water inlet function, leaks out of the water surface, and a large amount of air enters from then on to suspend the water inlet function of the siphon group to save water waste. When the backwashing is completed, it is also only necessary to close the high-pressure water control valve 201, and air will enter the single-valve speed control assembly 2 of the first siphon group 1 that performs the drainage function, stopping the drainage function of the siphon group. When the water level rises naturally, or the water flow is introduced into the speed control device 2 of the second siphon group 8 that performs the water inlet function through the high-pressure water control valve 201 to restore the water inlet, the mouth of the quick-drain pipe 204 is submerged in the water again to form a seal, and the second siphon group 8 restores the initial continuous water inlet state through the gravity exhaust device 6, and the filter pool resumes normal operation again. Compared with the siphon system that required at least 3 valves to control the filter pool in the past, the function of quickly controlling the operating state by linking other devices through a high-pressure water control valve 201 is realized.

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
