DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] As attached Figure 1 -Attached Figure 4 As shown, a self-priming tank includes a tank body 1, a water injection pipe 2 is connected to the upper part of the tank body 1, a water suction pipe 4 is penetrated on the upper part of the tank body 1, the upper end of the water suction pipe 4 is located outside the tank body 1 and connected to a water inlet flange 5, a water outlet pipe 10 is connected to the lower part of the side of the tank body 1, and the end of the water outlet pipe 10 away from the tank body 1 is connected to a water outlet flange 11, two layers of mounting frames 13 are installed in the tank body 1, and a defoamer 14 is arranged between the two layers of mounting frames 13. The defoamer 14 is made of steel wire mesh, and the upper mounting frame 13 is located below the lower end of the water suction pipe 4, and the lower mounting frame 13 is located above the connection between the water outlet pipe 10 and the tank body 1. The mounting frame 13 is in a tic-tac-toe grid structure.

[0019] The self-priming tank is used together with the water lifting equipment. Before the water lifting equipment is started, water from the outside enters the tank body 1 through the water injection pipe 2. When the water level in the tank body 1 exceeds the entire pump body of the water lifting equipment, that is, the pump body is completely filled with water, the self-priming effect is better at this time. Close the water injection pipe 2, start the water lifting equipment, and the water from the outside enters through the water suction pipe 4.

[0020] When water enters the water suction pipe 4, a large number of bubbles will be generated in the water flow, which will break up the water flow and reduce the flow rate of the water. Under the action of the bubbles, the water-lifting equipment is prone to wear and tear after long-term operation, which will accelerate the aging of the water-lifting equipment.

[0021] Installing the defoamer 14 plays a role in eliminating bubbles, can stabilize water pressure, reduce fluctuations, make the water pumping equipment run normally, and increase the service life of the water pumping equipment. At the same time, the defoamer 14 can also play a certain filtering role, filtering large-volume impurities.

[0022] The water injection pipe 2 is provided with a regulating valve 3, and the switch of the regulating valve 3 is used to control whether the external water enters the tank body 1 through the water injection pipe 2. A liquid level sensor 9 is provided inside the tank body 1, and the liquid level sensor 9 is electrically connected to the regulating valve 3. When the liquid level in the tank body 1 reaches the set point, the liquid level sensor 9 feeds back to the regulating valve 3, the regulating valve 3 is closed, and the external water stops entering.

[0023] A rectifying plate 12 is provided inside the tank body 1 . The rectifying plate 12 is located below the mounting frame 13 at the lower layer. The rectifying plate 12 is located above the connection between the water outlet pipe 10 and the tank body 1 .

[0024] Among the through holes formed on the rectifying plate 12 , the diameter of the through holes in the middle is larger than that of the through holes at the outer positions.

[0025] After the bubbles are eliminated from the water flow, the turbulent fluid is rectified and stabilized through the rectifying plate 12, so that the water flow into the water pumping equipment is more stable, thereby ensuring the stable operation of the water pumping equipment and increasing the service life of the water pumping equipment.

[0026] The lower end of the water suction pipe 4 is located in the tank body 1 and is connected to the expanding pipe 6. The diameter of the lower end of the expanding pipe 6 is greater than the diameter of the upper end. After the water flow passes through the expanding pipe 6, the range is expanded, increasing the contact with the defoamer 14, thereby better removing bubbles.

[0027] As attached Figure 4 As shown, a manhole 8 is provided on the side of the tank body 1, and the manhole 8 and the water outlet pipe 10 are respectively located on opposite sides of the tank body 1. Through the manhole 8, sewage can be removed and discharged to avoid blockage.

[0028] The mounting position of the mounting frame 13 corresponds to the connection between the manhole 8 and the tank body 1. The defoamer 14 is a cylindrical structure, the diameter of which is smaller than the diameter of the manhole 8, and the defoamer 14 can pass through the manhole 8, so that the staff can easily replace the defoamer 14 through the manhole 8.

[0029] An exhaust valve 7 is installed on the top of the tank body 1 to help the system discharge the gas with excessive pressure, so as to ensure the normal operation of the system; it can also remove the air dissolved in the water to prevent the gas from accumulating in the pipeline and affecting the flow of water.

[0030] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
