Description
Technical Field
The invention relates to the field of sewage treatment, in particular to a mechanical intermittent operation siphon drainage device.
Background
In the field of sewage treatment, siphon drainage is often applied to scenes such as rainwater collection and drainage, effluent drainage of a sedimentation tank and the like. The siphon drainage device can guide the liquid level in a drainage object into the object to be treated by siphon action for washing and other treatments when the liquid level in the drainage object is increased. The existing siphon drainage devices are passively treated by siphoning, namely, siphon drainage can be triggered when a drainage object meets the liquid level requirement, the drainage process cannot be effectively controlled, repeated drainage or flushing is very easy to occur under the condition of large continuous liquid flow in the drainage object, and the treatment effect of the object to be treated is easily influenced by excessive drainage caused by the repeated drainage. For the above phenomena, a control system is often constructed by adding an electromagnetic valve, a relay, a power supply device and the like based on a conventional control concept, which not only increases the manufacturing and construction costs of the device, but also reduces the overall reliability and service life of the device in the later use process.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a siphon drainage device, which can realize intermittent operation of the siphon drainage device on the premise of not introducing an active driving part, thereby ensuring the treatment effect of a working object of the siphon drainage device.
In order to solve the technical problem, the invention relates to a mechanical intermittent operation siphon drainage device, which comprises a siphon ascending pipeline and a siphon descending pipeline, wherein the siphon ascending pipeline is sleeved at the upper end of the siphon descending pipeline; the upper end of the siphon ascending pipeline is provided with a vent port which is opposite to the siphon descending pipeline, a spring cover plate is arranged in the vent port, a bearing container is hung on the spring cover plate and extends into the siphon descending pipe, and a flow guide hole is formed in the bottom end of the bearing container.
As an improvement of the invention, the pipe diameter of the siphon ascending pipe is 200-600 mm, and the pipe diameter of the siphon descending pipe is 70-550 mm.
As a modification of the present invention, the height difference between the lower end of the siphon-rising conduit and the upper end of the siphon-falling conduit is 400 to 1200mm.
As an improvement of the present invention, in the siphon lifting pipe, the diameter of the vent port gradually decreases from the inside of the siphon lifting pipe to the outside thereof, an elastic end body adopting an annular structure is arranged in the vent port, the elastic end body is made of rubber, and the radial section of the elastic end body adopts a triangular structure; the elastic end body comprises a first end face connected to the end face of the ventilation port and a second end face opposite to the axis of the ventilation port, and a compression chamber adopting a hollow structure is arranged between the first end face of the elastic end body and the end face of the ventilation port; the spring cover plate comprises a cover plate body arranged at the lower end of the ventilation port, the cover plate body is connected to the ventilation port through an elastic spring, a connecting end body is arranged at the upper end of the cover plate body, and the diameter of the connecting end body gradually rises from the inside of the siphon ascending pipeline to the outside of the siphon ascending pipeline.
By adopting the technical scheme, the spring cover plate can realize elastic connection processing through the elastic spring and can also perform auxiliary connection on the cover plate body and a bearing container hung on the cover plate body through mutual support processing formed between the connecting end body at the upper end of the cover plate body and the elastic end body in the connection process of the spring cover plate relative to the siphon ascending pipeline. When the bearing container suspended by the spring cover plate sinks due to the injection of liquid flow, the connecting end body moves downwards, the side end face of the connecting end body generates pressure on the second end face of the elastic end body, so that the elastic end body moves towards the first end face under the action of the pressure, and the compression chamber is further forced to be compressed, and the whole elastic end body is bent relative to the side wall of the ventilation port; at the moment, the elastic end body in the deformation state can enable the connecting end body to sink from the inside of the elastic end body, and then the spring cover plate integrally descends to break the siphon action of the siphon ascending pipeline.

By adopting the technical scheme, the elastic end body can keep a deformation state in the descending process of the connecting end body along with the spring cover plate through the arrangement of the limiting end plate, so that the connecting end body can complete the resetting treatment through the formed elastic end body after liquid flow in the bearing container is completely guided out through the flow guide holes.
As a modification of the invention, the upper edge of the carrying container is provided with a plurality of flow guide end plates which extend obliquely upwards through the edge of the carrying container, and the radial section of each flow guide end plate adopts a V-shaped structure.

After liquid flow is introduced into the siphon descending pipeline, the bearing container suspended in the siphon descending pipeline can be quickly filled by the liquid flow; in the process of keeping full pipe flow in the siphon descending pipeline, the inside of the bearing container can always be kept in a filling state. When the liquid flow in the drainage tank is gradually discharged along with the siphon phenomenon, the liquid levels in the drainage tank and the siphon ascending pipeline gradually descend, and when the liquid level descends to a certain height, the liquid flow in the siphon descending pipeline gradually reduces, so that full pipe flow cannot be formed; at this moment, the bearing container loses the buoyancy effect, and because its inside is filled with a large amount of liquid flows, so bearing container can drive spring cover plate and sink, and then make siphon ascending pipe upper end's vent port open to destroy siphon ascending pipe's leakproofness and siphon effect, the liquid level in drain tank and the siphon ascending pipe is in all height positions and can't form the siphon phenomenon promptly.

As an improvement of the invention, the pipe diameter of the siphon ascending pipe 1 is 200-600 mm, and the pipe diameter of the siphon descending pipe 2 is 70-550 mm.
As a modification of the present invention, the height difference between the lower end of the siphon-rising conduit 1 and the upper end of the siphon-falling conduit 2 is 400 to 1200mm.
In the actual working process of the mechanical intermittent operation siphon drainage device, the siphon drainage device needs to be arranged in a drainage tank which needs siphon drainage treatment, and after the siphon drainage device is arranged, a siphon descending pipeline extends into a drainage port of the drainage tank or a sewage pipeline. When drainage is carried out in the drainage tank or rainwater is accumulated, liquid flow in the drainage tank gradually enters the siphon ascending pipeline, and the liquid level in the siphon ascending pipeline ascends along with the liquid level in the drainage tank; when the liquid level in the siphon ascending pipeline is over the top end of the siphon descending pipeline, the siphon descending pipeline can trigger the siphon phenomenon, namely the liquid flow in the siphon ascending pipeline rapidly flows into the siphon descending pipeline.
After liquid flow is introduced into the siphon descending pipeline, the bearing container suspended in the siphon descending pipeline can be quickly filled by the liquid flow; in the process of keeping full pipe flow in the siphon descending pipeline, the inside of the bearing container can always be kept in a filling state. When the liquid flow in the drainage tank is gradually discharged along with the siphon phenomenon, the liquid levels in the drainage tank and the siphon ascending pipeline gradually descend, and when the liquid level descends to a certain height, the liquid flow in the siphon descending pipeline gradually reduces, so that full pipe flow cannot be formed; at this moment, the bearing container loses the buoyancy effect, and because its inside is filled with a large amount of liquid flows, so bearing container can drive spring cover plate and sink, and then make siphon ascending pipe upper end's vent port open to destroy siphon ascending pipe's leakproofness and siphon effect, the liquid level in drain tank and the siphon ascending pipe is in all height positions and can't form the siphon phenomenon promptly.
After the spring cover plate is opened, when the liquid flow in the bearing container is gradually led out through the flow guide hole at the bottom of the bearing container along with the time, the weight of the bearing container is gradually reduced until the liquid flow in the bearing container is emptied; at the moment, the bearing container cannot form effective tension on the elastic cover plate, so that the spring cover plate is reset, the ventilation port is closed, and the siphon ascending pipeline recovers the tightness; if the liquid level of the liquid flow in the drainage groove rises, the steps can be repeated to realize drainage treatment through the siphon effect.
Adopt above-mentioned technical scheme's mechanical type intermittent operation siphon drainage device, it can be compared in the drive processing of the bearing container to the spring apron in the siphon downcomer pipe of current passive siphon drainage device accessible to make siphon drainage device realize intermittent operation, and then effectively avoid traditional siphon drainage device easily to produce repeatedly the drainage or wash and lead to washing because too much and influence its treatment effect in the object. Meanwhile, the mechanical intermittent operation siphon drainage device in the application is realized based on the weight of liquid flow in the bearing container, and the rest driving parts are not involved in the operation process, so that the manufacturing cost and the operation stability of the device are obviously improved.
In addition, the mechanical intermittent operation siphon drainage device can change the time interval of two times of siphon triggering by adjusting the volume of the bearing container and the aperture of the diversion hole. In the actual operation process, when the aperture of the flow guide hole is kept unchanged, the volume of the bearing container is increased, and the time interval of two times of siphon triggering is increased; when the volume of the bearing container is unchanged, the aperture of the diversion hole is increased, and the time interval of two times of siphon triggering is reduced. Therefore, the siphon drainage device in the application can adjust the clearance movement period according to the actual working condition.
According to the hydraulics principle, the flow in the diversion hole is related to the liquid level difference and the aperture. The specific formula is as follows:
then:
for the present embodiment, H in the above formula is the vertical distance from the liquid level in the carrying container to the diversion hole. V Hole(s) Is the flow velocity of the liquid in the flow guide hole, S Hole(s) The aperture of the diversion hole is shown, and Q is the flow in the diversion hole. During actual operation, as the liquid in the carrying container flows out through the diversion holes, H is gradually reduced. The value of H should be calculated by the following integral:
in the formula: h 0 The current area of the upper liquid level of the bearing container in the filling state; s Cutting block Is the current area of the upper liquid level in the carrying container at time t. Based on the calculation method, the gap operation period of the mechanical intermittent operation siphon drainage device can be adjusted in real time based on the field working condition.
