Since sewage contains a large amount of waste, the pump pipes are prone to blockage, and frequent maintenance consumes a lot of manpower and material resources. In order to solve the blockage, existing sewage pumps generally use large-diameter pipes to reduce the degree of blockage. However, overly large pipes lead to increased flow, and large solid particles quickly hit the pump impeller along the water flow, accelerating the cavitation and damage of the pump. Therefore, a lift pump that reduces solid impact and prevents blockage is needed to meet the needs.

DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figures 1 to 8 As shown, an anti-blocking vertical lifting pump based on computer intelligent control includes a water inlet pipe 1 and an electric control box 5 for controlling the cross-sectional area of ​​the water inlet pipe 1, a vortex chamber 6 for pressurizing sewage and sending it to a high place, and a motor 7 for providing power. The water inlet pipe 1 includes a rotating shaft 2 for initially crushing blockages, a sealing ring 3 for preventing water leakage, and a sewage collecting box 4 for centrally recovering blockages. The top of the water inlet pipe 1 is connected to the vortex chamber 6, the electric control box 5 is arranged on the outer surface of the water inlet pipe 1, the motor 7 is installed on the top of the vortex chamber 6, the rotating shaft 2 is installed at the center of the water inlet pipe 1 and passes through the vortex chamber 6 to rotate coaxially with the motor 7, the sealing ring 3 is arranged at the connection between the electric control box 5 and the outer surface of the water inlet pipe 1, and the sewage collecting box 4 passes through the sealing ring 3 and is inserted into the pipe interior of the water inlet pipe 1.

[0028] The lifting pump sucks sewage from the bottom through the water inlet pipe 1, and the motor 7 supplies power to the vortex chamber 6 to pressurize the sewage, and then discharges the sewage after sucking it to a high place, so as to achieve the purpose of discharging the sewage. The electric control box 5 is connected to the computer to change the cross-sectional area inside the water inlet pipe 1, so as to facilitate the flow rate to be adjusted according to needs. The rotating shaft 2 is rotated by the motor 7 to send the sewage spiral to a high place, and at the same time, the large particles of solid and strip fibers in the sewage are preliminarily crushed to increase the flow rate of the sewage. The sewage collecting box 4 is used to collect some waste in the sewage to avoid the accumulation of waste and blockage of the water inlet pipe 1. Since the sewage collecting box 4 and the electric control box 5 are both arranged on the water inlet pipe 1, in order to prevent water leakage, the sealing ring 3 is used to locate the installation points of the sewage collecting box 4 and the electric control box 5.

[0029] See also Figure 3 and Figure 4 As shown, the rotating shaft 2 includes a threaded rod 21, a cutting blade 22, a cutting ring 23 and a retaining ring 24. The threaded rod 21 is arranged at both ends of the rotating shaft 2. The cutting blade 22 and the cutting ring 23 are alternately arrayed on the outer surface of the rotating shaft 2. The retaining ring 24 is arranged at the connection between the rotating shaft 2 and the threaded rod 21 and close to one side of the vortex chamber 6.

[0030] The threaded rod 21 is used to spirally send the sewage to a higher place, the cutting blade 22 and the cutting ring 23 are used to crush large particles of solid and strip fibers, and the retaining ring 24 is used to limit the crushed size of solids and fibers to avoid blockage caused by excessive size.

[0031] See also Figure 1 to Figure 5As shown, the dirt collecting box 4 includes a slot 41, a collecting frame 44, a sealing strip 42 and a lifting ring 43. The slot 41 is opened on the sealing ring 3. The collecting frame 44 is installed in the dirt collecting box 4 and passes through the sealing ring 3 and the wall of the water inlet pipe 1.

The strip fibers are wound through the support rod 444, and the collection rack 44 is pulled out to bring the waste out of the water inlet pipe 1.

[0035] See also Figure 1 to Figure 7 As shown, the electric control box 5 includes a wiring terminal 51, a rotating drum 52 and a baffle 53. The wiring terminal 51 is arranged on the surface of the electric control box 5 and connected to the rotating drum 52. The baffle 53 is installed on the top of the rotating drum 52 and is located in the water inlet pipe 1.

[0036] The connection terminal 51 is used to connect to a computer and the computer controls the rotation of the drum 52. The baffle 53 rotates around the drum 52 and fits with the size of the cutting ring 23. When the baffle 53 is perpendicular to the water flow direction, the cutting ring 23 and the baffle 53 can block most of the cross-section of the water inlet pipe 1, and the flow rate of the water inlet pipe 1 can be controlled by adjusting the cross-section.

[0038] The insertion hole 521 is used for installing and positioning the drum 52 , and the flow hole 522 is used for reducing the resistance encountered by the baffle 53 when rotating, and at the same time preventing the baffle 53 and the cutting ring 23 from completely blocking the cross section of the water inlet pipe 1 .

[0039] See also Figures 1 to 8As shown, the vortex chamber 6 includes a channel impeller 61, a flange pipe 62 and a drain pipe 63. The channel impeller 61 is installed in the center of the vortex chamber 6 and is connected to the motor 7. The flange pipe 62 is arranged on the lower surface of the vortex chamber 6 and is connected to the water inlet pipe 1. The drain pipe 63 is arranged on the side of the vortex chamber 6.

[0040] The channel impeller 61 has excellent sewage discharge capacity and can effectively prevent waste in the sewage from accumulating in the vortex chamber 6. The flange pipe 62 is used to install and connect the water inlet pipe 1, and at the same time facilitates the disassembly of the water inlet pipe 1 so as to quickly replace the parts inside the water inlet pipe 1. The sewage pipe 63 is used to discharge sewage laterally to achieve the purpose of improving the sewage flow path.

[0041] See also Figure 8 As shown, the channel impeller 61 includes a transmission shaft 611, a rear cover plate 612 and a front cover plate 613. One end of the transmission shaft 611 passes through the vortex chamber 6 and is connected to the motor 7, and the other end is connected to the rotating shaft 2. The rear cover plate 612 is arranged at the top of the channel impeller 61, and the front cover plate 613 is arranged at the bottom of the channel impeller 61.

[0042] The rotating shaft connects the channel impeller 61 and the rotating shaft 2, so that the motor 7 can power both and ensure that they can work synchronously. The front cover plate 613 and the rear cover plate 612 are used to prevent the solids in the sewage from directly impacting the channel impeller 61 and shortening its life, thereby effectively extending the maintenance cycle.
