Description

Technical Field

[0001] This utility model relates to the field of equipment inspection and maintenance, and in particular to a sand cleaning device for seawater channels. Background Technology

[0002] Industries such as steel metallurgy and chemical manufacturing located along the coast require seawater as circulating cooling water. Seawater is pumped to heat exchange equipment. Typically, each seawater pump has a seawater inlet channel, 3 meters high and 4.5 meters wide, located at a water depth of 10 meters. Each seawater channel is equipped with a steel gate, measuring 3 meters x 4.5 meters. During pump operation, the seawater flow accelerates, carrying and depositing a large amount of silt and sand in the inlet channel. If the silt and sand around the steel gate is not cleaned during pump maintenance, the gate may not close properly, hindering maintenance work on the seawater channel.

[0003] Currently, most companies rely on divers to manually clean the mud and sand around the gate at a depth of 10 meters. This method is labor-intensive, costly, and dangerous. Using submersible sewage pumps directly results in poor cleaning efficiency because the mud and sand deposited in the seawater channel cannot be concentrated and transported to the pump inlet. Therefore, there is a need to invent a new type of seawater channel sand cleaning device that has excellent cleaning effect and requires no manual operation. Utility Model Content

[0004] This utility model provides a seawater channel sand cleaning device, which solves the problems of existing manual sand cleaning methods, such as large workload, high cost and high risk, and poor sand cleaning effect of submersible sewage pumps.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A seawater channel sand removal device includes a main frame. A pneumatic sewage pipe is installed on the left and right sides of the main frame, and the two pneumatic sewage pipes are connected by a first connecting pipe. The middle part of the first connecting pipe is connected to the lower end of an air inlet pipe. The upper end of the air inlet pipe protrudes from the upper part of the main frame and is connected to an external compressed air pipe. The upper end of the pneumatic sewage pipe protrudes from the upper part of the main frame and is connected to a sewage tank. A water inlet pipe is installed on the main frame inside the pneumatic sewage pipe. The lower end of the water inlet pipe is connected to the upper end of a second connecting pipe. The lower end of the second connecting pipe is connected to several nozzles.

[0007] Furthermore, the main frame is positioned above the sediment deposited on the gate, with both ends of the main frame located within the gate's track.

[0008] Furthermore, a lifting ring is provided at the top of the main frame.

[0009] Furthermore, the lower surface of the main frame is connected to the upper end of the support, and the lower end of the support is in contact with the ground below the silt deposited by the gate.

[0010] Furthermore, the pneumatic sewage pipe is arranged longitudinally, the first connecting pipe is arranged laterally, the air inlet pipe is arranged longitudinally, the water inlet pipe is arranged longitudinally, and the second connecting pipe is arranged laterally.

[0011] Furthermore, the lower end of the pneumatic sewage pipe is located above the sludge deposited by the gate, and the lower end of the nozzle is located above the sludge deposited by the gate.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention utilizes pressurized seawater sprayed through nozzles to increase flow velocity and clean the mud and sand at the lower end of the main frame. Simultaneously, compressed air enters the device, forcing water out of the pneumatic sewage pipe. The negative pressure created when the air is discharged forces the concentrated sand-water mixture (mud, water, and compressed air) to be discharged into the sewage tank through the pneumatic sewage pipe. This combination of hydraulic impact and pneumatic conveying effectively removes large amounts of sediment and sand from the seawater channel, solving the problem of poor sand removal efficiency caused by the difficulty of traditional submersible pumps in collecting sediment. It improves the efficiency and quality of sand removal and creates favorable conditions for the maintenance of seawater pumps.

[0014] This utility model device eliminates the need for personnel to work underwater. Simply lower the sand-removing device to the predetermined position along the steel gate track using a crane, and connect the water hose and compressed air pipe to automatically perform the sand-removing operation. This greatly reduces manpower input and lowers labor costs, while also avoiding the life-threatening dangers that divers may face when working underwater, thus improving the safety of the operation.

[0015] The entire device consists of basic components such as a seawater channel sand cleaning device frame, flushing water pipes, compressed air inlet pipes, nozzles, pneumatic sewage discharge pipes, and supports. Its structural design is simple and reasonable, making it easy to manufacture and assemble. During operation, simply connect the water inlet and air inlet according to the set steps, secure the device with lifting rings, and lower it to start the sand cleaning work. No complicated operating procedures or long-term professional monitoring are required, making it suitable for widespread application in coastal steel metallurgy, chemical, and other industries. It is easily accepted and promoted by various enterprises, effectively meeting the need for sand cleaning of seawater channels before maintenance and improving production and maintenance efficiency.

[0028] This utility model provides a technical solution: a seawater channel sand removal device, such as... Figure 1 and 2 As shown, the system includes a main frame 1, which is positioned above the sludge deposited on the gate 8. Both ends of the main frame 1 are located within the gate's track 9. A lifting ring 10 is installed at the top of the main frame 1.

[0030] The main body of this utility model is a main frame that can move up and down along the steel gate track.

Two water inlets, one compressed air inlet and two nozzles are provided at the upper end of the main frame. There is a pneumatic sewage pipe at each end of the main frame. Eight water outlets and two supports are provided at the bottom of the frame. When the seawater channel needs maintenance, connect the water hose to the inlet and the compressed air pipe to the air inlet. Secure them with steel wire ropes via two lifting rings. Use a crane to lower the sand cleaning device along the steel gate track to the bottom of the seawater channel. After being pressurized, the seawater enters the sand cleaning device through the water hose. After passing through eight nozzles, the flow velocity increases, cleaning the mud and sand at the lower end of the main frame. The maintenance compressed air enters the sand cleaning device through the air inlet. The compressed air pressure is 0.2~0.7MPa. The water in the pneumatic sewage pipe is forced out by the compressed air. During the gas discharge process, the lower part of the pneumatic sewage pipe becomes negative pressure. Subsequently, the concentrated sand water composed of mud, sand, water, and compressed air is discharged from the pneumatic sewage pipe to the sewage tank, which plays the role of cleaning the mud and sand in the seawater channel.
