Description

Technical Field

[0001] The present invention relates to the field of sewage treatment equipment, and particularly to a multi-functional siphon pump protection device for sedimentation tanks in sewage treatment plants. Background Art

[0002] In sedimentation tanks of sewage treatment plants, siphon is used to form sludge reflux. The components in sewage are very complex, mainly solids and liquids. Some solids are large particles, insoluble substances, metals, etc. During the use of siphon pumps, due to untimely closing of the outlet valve, sewage accompanied by a large amount of solid debris often enters the siphon pump, causing corrosion of the impeller and even damage to the pump.

[0003] In summary, at present, siphon is used to form sludge reflux in sedimentation tanks of urban sewage treatment plants. Since it is difficult to avoid losses during the operation of siphon pumps, this is a common problem in actual engineering applications. In severe cases, it may lead to the paralysis of the entire treatment system. Currently, the losses during the operation of siphon pumps in actual sewage treatment plants cannot be effectively solved, and there is an urgent need for a protection device for siphon pumps in sedimentation tanks of sewage treatment plants. Summary of the Invention

[0004] At present, siphon is mainly used to form sludge reflux in sedimentation tanks of urban sewage treatment plants. In order to avoid the phenomenon that sewage accompanied by a large amount of solid debris enters the siphon pump due to untimely closing of the outlet valve, resulting in corrosion of the impeller and even damage to the pump. The present invention provides a multi-functional siphon pump protection device for sedimentation tanks in sewage treatment plants.

[0005] The purpose of the present invention is to reduce the above-mentioned solids when the siphon pump sucks sewage, so that the sewage passes through a series of device pipes before the pump to avoid sucking the sewage into the siphon pump. The core of the present invention is to add a strong magnetic box and a vacuum box to the siphon pump pipeline. The outlet valve of the vacuum box adopts a float switch to ensure that when a certain water level is reached, the outlet valve is automatically closed to stop the water, so as to avoid sewage and reduce solid debris from entering the siphon pump and accelerating the loss of the pump.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A multi-functional siphon pump protection device for sedimentation tanks in sewage treatment plants, the narrow end of the horn-shaped structure is connected with a pipeline, the wide end is detachably connected with one end of the strong magnetic box, the other end of the strong magnetic box is connected with the vacuum box through a pipeline, the other end of the vacuum box is connected with the siphon pump through a pipeline, and valves are provided at the connection between the pipeline and the horn-shaped structure and at the connection between the pipeline and the strong magnetic box.

[0008] Further, the horn-shaped structure is a double-layer structure, the outer layer is a rubber layer, and the inner layer is a stainless steel layer.

[0009] Further, the strong magnetic box is a three-layer box body, the outer layer is a rubber layer, the middle layer is an iron sheet layer, and the inner layer is a stainless steel layer.

[0010] Further, the top of the middle iron sheet layer of the strong magnetic box is the positive electrode, and the bottom is the negative electrode.

[0011] Further, the vacuum box is of a double-layer structure, with the outer layer being a stainless steel layer and the inner layer being an integrally formed reinforced glass sphere. A float switch is provided inside the vacuum box, and a sewage discharge port is provided at the bottom of the vacuum box.

[0012] Further, the pipeline is detachably connected to the horn-shaped structure, the strong magnetic box, the vacuum box, and the siphon pump.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, a strong magnetic box and a vacuum box are provided in front of the siphon pump. In the strong magnetic box, when sewage enters, the electrodes are energized, making the strong magnetic box magnetic. This strong magnetism causes larger solid debris in the sewage to be wrapped by the magnetic contaminants in the sewage and covered inside the strong magnetic box. When the sewage enters the vacuum box, as the water level in the vacuum box rises, the float switch will automatically open the sewage discharge port switch at the bottom, thereby achieving the effect of further improving the quality of the sewage and protecting the siphon pump. When the operation is over, just cut off the power supply, the magnetism is cancelled, and the contaminants can be removed only by disassembling the pipeline and the connection port.

[0015] Using this device can greatly improve the quality of sewage, further reduce the solid debris in the sewage treatment system, and avoid the situation in the traditional mode where due to improper manual operation, the outlet valve is not closed in time, causing water to enter the siphon pump and resulting in corrosion of the impeller; this device has good corrosion resistance and a long service life, can meet the harsh conditions of the sewage treatment plant, and can improve the overall effect of the sewage treatment system.

[0016] This device mainly decontaminates the sewage during the sludge reflux process of the siphon pump through the physical structure and working effects of the two boxes. The corrosion resistance is due to the use of materials such as stainless steel and tempered glass as the main body, and the extension of the service life of the siphon pump is due to the working effect of the float switch, which makes the sewage stop entering when it reaches a certain height, so that the siphon pump will not be damaged by the sewage passing through.

[0023] The present invention will be described in detail below through specific embodiments, but the protection scope of the present invention is not limited. Unless otherwise specified, the experimental methods used in the present invention are all conventional methods, and the experimental equipment, materials, reagents, etc. used can be obtained from commercial channels.

[0024] Embodiment 1

[0025] A multifunctional siphon pump protection device for a sedimentation tank in a sewage treatment plant includes a pipeline 1, a valve 2, a strong magnetic box 3, a vacuum box 4, a float switch 5, and a siphon pump 6.

[0026] The pipeline 1 connects the strong magnetic box 3, the vacuum box 4, and the siphon pump 6 through a connection port, that is, the strong magnetic box 3 and the vacuum box 4 are connected by the pipeline 1 through the connection port, and the pipeline 1 and the connection port are detachable.

[0027] This pipeline 1, strong magnetic box 3, vacuum box 4, and siphon pump 6 can be appropriately changed according to the size of the sedimentation tank in a specific sewage treatment plant and the requirements of the operation. The strong magnetic box 3 connected to the water outlet end of the pipeline is a three-layer box body, with a rubber layer on the outer layer, an iron sheet layer in the middle layer, and a stainless steel layer on the inner layer. The water inlet end of the strong magnetic box 3 is a horn-shaped structure 10 that is narrow on the left and open on the right. The horn-shaped structure 10 is connected to the left side of the strong magnetic box 3 and is detachable. The horn-shaped structure 10 is a double-layer structure, with a rubber layer on the outer layer and a stainless steel layer on the inner layer. The vacuum box 4 is a reinforced glass box with a float switch 5. One end at the bottom on the left side is the water inlet end, and one end at the top on the right side of the glass box is the water outlet end. And the water outlet end in the direction of the siphon pump can also be used as an overflow port in actual application. A sewage outlet 9 controlled by the float switch 5 is provided at the bottom. The outer shell of this glass box is designed as a stainless steel layer. All the outer shells mentioned above are designed to withstand a pressure of about 8 m of water depth at least and are suitable for long-term use in harsh water quality conditions. Sewage outlets are provided at the bottom. In actual application, the rubber layer of the strong magnetic box 3 plays an insulating role when electrified, preventing electric leakage into the water tank, and can protect the box body during collisions.

[0028] The iron sheet layer generates magnetism when electrified, which is used to adsorb some solid pollutants in the sewage. When adsorbing, the solid contacts the surface of the stainless steel layer.

[0029] The stainless steel layer protects the box body from the inside to prevent the box body from being corroded by sewage.

[0030] The AC power line enters from the left horn-shaped structure opening and is connected to the middle iron sheet layer of the strong magnetic box 3, which is arranged at the top and bottom of the strong magnetic box 3 body. The top is the positive pole and the bottom is the negative pole. After being powered on, a magnetic field is generated between each pair, and the magnetism disappears when the power is off.

[0031] The vacuum box 4 has a double-layer structure. The outer layer is a stainless steel layer, and the inner layer is an integrally formed reinforced glass sphere. There is a float switch 5 inside. The left side of the vacuum box 4 body is the water inlet end, the upper right side has a water outlet end, and the bottom has a sewage outlet 9 controlled by a float switch 5. The reinforced glass is an integrally formed spherical structure to withstand the pressure during vacuum pumping. The stainless steel layer is used as the outer shell to wrap the internal reinforced glass sphere to resist sewage corrosion. When this sphere is manufactured, the three openings are also made at the same time, and the shape is a thread. This thread can be stably connected to the valves at the three openings and is installed in a knob type.

[0032] The above is only the preferred specific implementation manner of the present invention, and it does not represent that the present invention is limited thereto. Any modifications, equivalent replacements, and improvements made by those skilled in the art within the technical scope and principles disclosed by the present invention should be covered within the protection scope of the present invention.
