Description

Technical Field

[0001] The present application relates to the technical field of water treatment filter equipment, and in particular to a constant liquid level water outlet device for an upper water inlet filter. Background Art

[0002] Currently, in the field of water treatment, filters are key filtration equipment used to remove impurities from water. Top-inlet filters are a common type of filter, characterized by water intake from the top. However, existing top-inlet filters have certain shortcomings in effluent control, such as large liquid level fluctuations, which affect filtration effectiveness and equipment stability.

[0003] In reality, bottom water discharge applied to filter tanks or other places requires a device that can maintain a high liquid level and constant liquid level discharge. Traditional constant liquid level discharge relies on liquid level gauges, electric valves and related control programs. Electric valves start and stop frequently, have a high failure rate and high cost. Utility Model Content

[0004] In order to achieve constant liquid level water outlet of the filter tank with simple structure and low cost, the present application provides a constant liquid level water outlet device for an upper water inlet filter tank.

[0005] The present application provides a constant liquid level water outlet device for an upper water inlet filter tank, which adopts the following technical solution:

[0006] A constant liquid level water outlet device for an upper water inlet filter tank comprises a filter tank, a filter layer is arranged in the filter tank, and a communicating vessel, the communicating vessel comprising an inlet pipe, a transverse pipe and an outlet pipe, the filter layer in the filter tank is arranged at a height that does not fit the tank bottom, the inlet pipe and the outlet pipe respectively vertically penetrate the filter layer, the bottom opening of the inlet pipe is arranged as a water inlet, the bottom opening of the outlet pipe is arranged as a water outlet, the transverse pipe is arranged horizontally, and the height of the transverse pipe is higher than the filter layer, and the transverse pipe is fixedly connected to the inlet pipe and the outlet pipe respectively.

[0007] By adopting the above technical solution, after the turbid water enters the filter tank, it is filtered through the filter layer and then enters the bottom of the filter tank. The filtered turbid water becomes clean water, and then the clean water enters the water inlet pipe, the cross pipe and the water outlet pipe in turn, and is finally discharged out of the filter tank. Among them, when the water level inside the filter tank is higher than the bottom end of the cross pipe, the filtered clean water can be discharged from the filter tank through the cross pipe. When the water level inside the filter tank is lower than the bottom end of the cross pipe, the clean water is inside the water inlet pipe and cannot enter the cross pipe. At this time, the clean water cannot be discharged from the filter tank. At this time, turbid water is continuously injected into the filter tank, causing the liquid level in the filter tank to rise, thereby achieving the effect of discharging the clean water out of the filter tank. In this way, the purpose can be achieved using a simple-structured communicating vessel without the need for complex control systems and components such as electric valves, which reduces manufacturing costs and maintenance costs, reduces the failure rate of equipment, and improves the stability of the system.

[0008] Optionally, a first sleeve is slidably connected to the inside of the water inlet pipe, the first sleeve passes through the water inlet pipe and extends into the inside of the transverse pipe, and a second sleeve is slidably connected to the inside of the water outlet pipe, the second sleeve passes through the water outlet pipe and extends into the inside of the transverse pipe. A lifting component is provided in the transverse pipe for driving the first and second sleeves to rise and fall simultaneously.

[0009] By adopting the above technical solution, the lifting assembly drives the lifting of the first sleeve and the second sleeve at the same time, which can change the water level of the water inlet pipe entering the horizontal pipe and the water level flowing from the horizontal pipe into the outlet pipe. That is, if the first sleeve and the second sleeve are set at a height higher than the bottom end of the horizontal pipe, the water in the filter tank can only exist in the water inlet pipe and cannot flow into the horizontal pipe.

[0010] Optionally, the lifting assembly includes a shell, a bracket and a drive rod, the shell is fixed to the bottom of the transverse tube, the bracket is fixedly connected to the first sleeve and the second sleeve respectively, the drive rod passes through the bottom of the transverse tube and is rotatably connected to the transverse tube, the rotation axis direction of the drive rod is along the vertical direction, the drive rod is threadedly connected to the bracket, and a drive motor for driving the drive rod to rotate is fixed in the shell.

[0011] By adopting the above technical solution, the driving motor drives the driving rod to rotate, the driving rod and the bracket move in a threaded manner, and the bracket is fixed to the first sleeve and the second sleeve respectively, so as to realize the guide limit of the bracket, thereby realizing the lifting and lowering of the bracket, that is, the lifting and lowering of the first sleeve and the second sleeve can be realized.

[0012] Optionally, the top ends of the first sleeve and the second sleeve are both slidably connected with a first sealing plate and a second sealing plate. When the first sealing plate and the second sealing plate are closed, the first sleeve and the second sleeve are sealed respectively. An opening and closing assembly for driving the first sealing plate and the second sealing plate to open and close is provided in the transverse tube.

[0013] By adopting the above technical solution, the opening and closing assembly controls the opening and closing of the first sealing plate and the second sealing plate, thereby changing the opening degree of the first sleeve and the second sleeve, that is, changing the flow rate and flow of the water inlet pipe and the water outlet pipe.

[0014] Optionally, the opening and closing assembly includes a first screw block, a second screw block and a bidirectional screw sleeve, the first screw block is fixed to the first sealing plate, the second screw block is fixed to the second sealing plate, the first screw block and the second screw block are respectively threadedly connected to the bidirectional screw sleeve, and are axially symmetrically arranged along the center position of the bidirectional screw sleeve, the bidirectional screw sleeve rotates relative to the horizontal tube, and the rotation axis direction of the bidirectional screw sleeve is along the horizontal direction.

[0015] By adopting the above technical solution, when the bidirectional screw sleeve rotates, it moves with the first screw block and the second screw block respectively. Since the first screw block and the second screw block are symmetrically arranged along the bidirectional screw sleeve, the first screw block and the second screw block can move away from or approach each other relative to the bidirectional screw sleeve at the same time.

[0016] Optionally, the bidirectional screw sleeve is sleeved on the bracket, a gear ring is fixed on the bidirectional screw sleeve, an active tooth is rotatably connected to the bracket, a connecting rod is horizontally arranged in the transverse tube, a first reversing tooth and a second reversing tooth are fixed on the connecting rod, the first reversing tooth is engaged with the active tooth, and the second reversing tooth is engaged with the gear ring.

[0017] By adopting the above technical solution, the active tooth rotates, and the active tooth engages with the first reversing tooth to drive the connecting rod to rotate. The rotation of the connecting rod drives the second reversing tooth to rotate, and the second reversing tooth engages with the gear ring, thereby achieving the purpose of driving the bidirectional screw sleeve to rotate.

[0018] Optionally, concave and convex blocks are respectively provided on the sides of the first sealing plate and the second sealing plate that are close to each other, and the concave and convex blocks are inserted into each other for sealing.

[0019] By adopting the above technical solution, when the first sealing plate and the second sealing plate are closed, the first sleeve and the second sleeve can be better sealed through the insertion and sealing of the concave and convex blocks, and the sealing effect is better.

[0020] Optionally, a sleeve is fixed to the top of each of the first sleeve and the second sleeve, and the diameter of the sleeve is larger than the diameter of the first sleeve and the second sleeve.

[0021] By adopting the above technical solution, the diameter of the sleeve on the first sleeve and the second sleeve is larger than the diameter of the sleeve itself, which can prevent the first sleeve and the second sleeve from slipping out of the water inlet pipe and the water outlet pipe, and increase the stability of the first sleeve and the second sleeve.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The driving rod rotates, and the driving rod is threadedly connected to the bracket. In addition, the bracket is fixed to the first sleeve and the second sleeve respectively, so that the bracket can be driven to rise and fall, thereby realizing the simultaneous driving of the first sleeve and the second sleeve. If the first sleeve and the second sleeve are raised to a height exceeding the bottom end of the horizontal pipe, the water in the filter tank can only stay in the water inlet pipe and cannot enter the horizontal pipe, or cannot flow from the horizontal pipe into the water outlet pipe. Therefore, it is necessary to continue to inject turbid water into the filter tank to increase the liquid level in the filter tank, thereby achieving the purpose of changing the water level in the filter tank;

[0024] 2. When the driving rod rotates, it drives the active gear to rotate. The active gear engages with the first reversing gear, and then the second reversing gear rotates through the transmission of the connecting rod. Then the second reversing gear engages with the gear ring to achieve the purpose of driving the bidirectional screw sleeve to rotate, thereby realizing the threaded movement of the first screw block and the second screw block, and achieving the effect of synchronous opening and closing of the first sealing plate and the second sealing plate.

[0028] The following is combined with Figure 1-Figure 2 This application is described in further detail.

[0029] The embodiment of the present application discloses a constant liquid level water outlet device for an upper water inlet filter tank.

[0037] The implementation principle of a constant liquid level water outlet device for an upper water inlet filter tank in the embodiment of the present application is as follows: turbid water entering the filter tank is filtered through the filter layer 1 and enters the bottom of the filter tank. At this time, the turbid water becomes clean water, and then the clean water enters the water inlet pipe 21, the transverse pipe 22 and the water outlet pipe 23 in sequence, and is finally discharged out of the filter tank. When the water level inside the filter tank is higher than the bottom end of the transverse pipe 22, the filtered clean water can be discharged from the filter tank through the transverse pipe 22. When the water level inside the filter tank is lower than the bottom end of the transverse pipe 22, the clean water cannot enter the transverse pipe 22, and the clean water cannot be discharged from the filter tank. At this time, turbid water needs to be continuously injected into the filter tank to raise the liquid level in the filter tank before the clean water can be discharged from the filter tank. The first sleeve 212 and the second sleeve 232 in the water inlet pipe 21 and the water outlet pipe 23 can change their heights through the lifting component 3, thereby achieving the change of the liquid level height entering the transverse pipe 22. In addition, the flow rate and flow rate of the clean water can also be controlled by controlling the opening and closing of the first sealing plate 26 and the second sealing plate 27.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
