Description

Technical Field

[0001] The utility model belongs to the technical field of drainage flow limiting, and particularly relates to an adjustable drainage device. Background Technique

[0002] In the field of environmental protection engineering, sedimentation tanks are common water-solid separation devices in water treatment. For example, slurry adjustment tanks, flocculation sedimentation tanks, etc. all belong to sedimentation tanks. In sedimentation tanks, after the water to be treated undergoes solid-liquid separation, it is often discharged by overflow through an overflow port set in the sedimentation tank or pumped out by a pump. However, usually, the pumping is carried out by directly inserting a pipeline into the clear water part at the upper part of the sedimentation tank. Since the clear water at the upper part of the sedimentation tank contains impurities, it is easy to block the pipeline and enter the water pump, blocking the pump. In severe cases, it will also affect the normal use of the pump.

[0003] A patent document with the patent number CN212715246U was retrieved. It discloses a drainage flow limiting and adjusting device, including an outer box. The top inside the outer box is welded with a housing. A first motor is fixed inside the housing. The output end of the first motor is welded with a first gear. The first gear meshes with a second gear. The bottom of the second gear is welded with a threaded rod. A limiting rod is fixed at the bottom of the housing. A moving block is installed on the outer sides of the threaded rod and the limiting rod. A support plate is installed at the bottom of the threaded rod and the limiting rod. A baffle is welded inside the other side of the moving block. A battery box is fixed on one side of the top of the support plate, and a storage battery is fixed inside the battery box. When the device needs to limit the water flow, by starting the first motor, the output end of the first motor rotates, thereby driving the first gear to rotate. Through the rotation of the first gear, the second gear is driven to rotate. Through the rotation of the second gear, the threaded rod is driven to rotate. Then, through the threaded connection between the threaded rod and the moving block, the threaded rod transmits the rotational force to the moving block. And through the limitation of the moving block by the limiting rod, the moving block converts the rotational force into a moving force, so that the moving block moves up and down along the limiting rod, and then the moving block drives the baffle to move up and down, thereby limiting the water inside the outer box. When the filter screen needs to be cleaned, start the second motor. The second motor drives the first rotating rod and the first bevel gear to rotate. Through the meshing connection between the first bevel gear and the second bevel gear, the first bevel gear can drive the second bevel gear and the second rotating rod to rotate. Then through the rotation of the second rotating rod, the cleaning disc is driven to rotate, so that the filter screen can be cleaned by the cleaning brush on one side of the cleaning disc.

[0004] However, the operations of flow limiting and filter screen cleaning are too cumbersome, and the corresponding structure is also complex. It includes a large number of motors, gears, rotating rods, etc. that cooperate with each other to achieve the functions. As a result, the manufacturing cost is high, and at the same time, because it is used for water, the motors and gears are prone to rust and damage, which is not conducive to long-term use.

[0033] Embodiment:

[0034] Referring to Figure 1-6 An adjustable drainage device shown, including an outlet pipe 1 and an inlet pipe 2 rotatably sleeved. A secondary filtering structure 5 and a cleaning mechanism 6 are arranged in the outlet pipe 1, and the cleaning mechanism 6 is used to clean impurities on the surface of the secondary filtering structure 5, and the end of the cleaning mechanism 6 is connected to the inner wall of the inlet pipe 2. A driving mechanism 3 adapted thereto is also arranged in the inlet pipe 2, and the driving mechanism 3 is used to drive the inlet pipe 2 to rotate relative to the outlet pipe 1. A flow limiting mechanism 7 is also arranged in the outlet pipe 1 to perform a flow limiting operation on the filtered sewage, and the flow rate passing through the outlet pipe 1 can be adjusted according to requirements;

[0035] Specifically, the filtering structure 5 is a conical structure, and a first filter screen 501 is arranged around its surface. The cleaning mechanism 6 is used in cooperation with the first filter screen 501 to clean impurities attached to the surface of the first filter screen 501 in a timely manner;

[0036] Specifically, the cleaning mechanism 6 is a Y-shaped structure, including a connecting rod 601 and two rotating rods 602. The end of the connecting rod 601 is connected to the inside of the inlet pipe 2 and is arranged at the center point of the inlet pipe 2; the two rotating rods 602 are arranged in a V shape at the other end of the connecting rod 601; a number of soft bristles 603 are arranged on one side of the rotating rod 602, and the soft bristles 603 are used to remove impurities on the surface of the first filter screen 501; when in use, when the inlet pipe 2 rotates, it drives the connecting rod 601 to rotate, and the connecting rod 601 drives the rotating rod 602 to rotate, so that the soft bristles 603 clean the surface of the first filter screen 501;

[0037] The rotation of the inlet pipe 2 depends on the driving mechanism and the action of the water flow. When the water pump pumps water, the water flow enters from the inlet pipe 2, and the water flow drives the driving mechanism 3 to rotate, and the driving mechanism 3 drives the inlet pipe 2 to rotate; preferably, the driving mechanism 3 is a rotating impeller, and the end of the blade of the rotating impeller 3 is fixedly connected to the inner wall of the inlet pipe 2;

[0038] Specifically, the flow-limiting mechanism 7 includes a fixed ring 701, a number of flow-limiting flaps 702, and a baffle 703. The fixed ring 701 is fixedly arranged on the inner cavity wall of the water outlet pipe 1. The number of flow-limiting flaps 702 is rotatably arranged on the fixed ring 701, and a plurality of flow-limiting flaps 702 arranged on the fixed ring 701 form a circular structure. The baffle 703 is arranged on the inner wall of the water outlet pipe 1 and is adapted to the flow-limiting flaps 702, so that under the action of gravity and the baffle 703, the flow-limiting flaps 702 close the inner cavity of the water outlet pipe 1.

[0039] Considering the filtration of larger impurities, a second filter screen 4 is also arranged in the water inlet pipe 2. The second filter screen 4 realizes the filtration of larger impurities in the water and is also the first filtration. Therefore, the mesh holes of the second filter screen 4 are larger than those of the first filter screen 501, and the first filter screen 501 is for secondary filtration. When the second filter screen 4 is provided, the end of the connecting rod 601 can be connected to the center position of the second filter screen 4. The rotation of the water inlet pipe 2 drives the second filter screen 4 to rotate, and the second filter screen 4 drives the connecting rod 601 to rotate self.

[0040] For the specific structure of the rotational socket joint between the water outlet pipe 1 and the water inlet pipe 2, a rotating block 201 is fixedly arranged on the outer side of the end of the water inlet pipe 2, and a rotating groove 101 is formed in the inner wall of the end of the water outlet pipe 1. The rotating block 201 is movably embedded in the rotating groove 101. Through the cooperation of the rotating block 201 and the rotating groove 101, the water inlet pipe 2 can rotate relative to the water outlet pipe 1.

[0041] The usage process and principle of the adjustable drainage device in this preferred embodiment are as follows: When it is necessary to pump and drain the clear water on the upper layer in the sedimentation tank, use a hoisting tool to vertically hoist and fix this device directly above the sedimentation tank, place the end of the water inlet pipe 2 into the water, and then connect the water outlet end of the water outlet pipe 1 to the water inlet end of the water pump through a water conveyance hose.

[0042] Turn on the water pump. Water enters from the end of the water inlet pipe 2. The water flow power drives the driving mechanism 3 to rotate. The driving mechanism drives the water inlet pipe 2 to rotate relative to the water outlet pipe 1. At the same time, the second filter screen 4 conducts the first layer of filtration on the water flow entering the water inlet pipe 2. The second filter screen 4 rotates while filtering, and the rotation of the second filter screen 4 drives the connecting rod 601 to rotate self. The connecting rod 601 drives the rotating rod 602 to rotate. The rotation of the rotating rod 602 drives the soft brush hairs thereon to clean the surface of the filtering structure 5, so that impurities will not deposit on the surface of the filtering structure 5, facilitating the passage of water flow.

[0043] While the water pump is pumping water, the water flow passes through the filtering structure 5 and then through the flow-limiting mechanism 7. Under normal conditions, the flow-limiting flap 702 closes the inner cavity of the water outlet pipe 1 under the action of gravity. When the water pump is started, under the action of the water pump, the flow-limiting flap 702 rotates towards the water outlet direction, allowing the water flow to pass through the water outlet pipe 1 smoothly and then be discharged. The flow-limiting of the water flow by the flow-limiting flap 702 is adjusted by the power of the water pump.

[0044] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
