Furthermore, traditional sewage pumps also need improvement in terms of corrosion resistance, sealing, and functional integration. Utility Model Content

[0003] The purpose of this utility model is to provide a built-in sewage pump that solves the above problems. It has a compact structure, is easy to install, highly adjustable, highly integrated, and corrosion resistant.

[0004] Technical Solution: This utility model provides a tank-mounted sewage pump, including: a built-in sewage pump motor, an adjustable mounting platform, a ventilation connector, and a discharge connector. A suction and discharge port is located below the built-in sewage pump motor. The adjustable mounting platform includes an adjustable bolt and a mounting cover. The built-in sewage pump motor is connected to the adjustable bolt via a connecting plate. The mounting cover is connected above the adjustable bolt and fixed above the sewage tank. The adjustable bolt's height is adjustable according to the tank's depth. The ventilation connector is located above the mounting cover. The discharge connector is located above the mounting cover, with an adjustable hose below it. The adjustable hose is connected to the suction and discharge port.

[0005] Furthermore, in the aforementioned box-type sewage pump, the built-in motor is a fully sealed design made of acid and alkali resistant plastic. This allows it to withstand corrosion from sewage, septic tanks, and other similar environments, ensuring safe operation in liquid environments.

[0006] Furthermore, in the aforementioned box-type built-in sewage pump, the suction and discharge ports are made of copper alloy, which has good corrosion resistance and structural strength, and can operate reliably for a long time.

[0007] Furthermore, in the aforementioned tank-mounted sewage pump, a DC power terminal is arranged on the upper part of the mounting cover, and a level gauge is integrated above the sewage tank.

[0008] Furthermore, in the aforementioned tank-type sewage pump, a mounting plate is provided below the built-in motor. The mounting plate is installed inside the sewage tank by means of fixed elastic bolts, which helps to stabilize the pump body and reduce operating vibration.

[0009] Furthermore, in the aforementioned box-type built-in sewage pump, both the ventilation connector and the discharge connector are made of copper alloy to ensure the durability of the interfaces.

[0010] Furthermore, in the aforementioned box-type built-in sewage pump, the ventilation connector and the discharge connector are respectively connected to a ventilation hose and a discharge hose. The ventilation hose is a 1 / 2” or 5 / 8” inner diameter hose, and the discharge hose is a 3 / 4” inner diameter hose, to adapt to different ventilation and discharge flow requirements.

[0011] As can be seen from the above technical solution, this utility model has the following beneficial effects: The built-in sewage pump of this utility model can flexibly adjust the installation height of the pump body according to the actual depth of the box through adjustable bolts, realizing customized adaptation, improving the versatility of the product, and simplifying inventory management; The sewage pump is completely built into the box, and the top mounting cover integrates the interfaces for discharge, ventilation, electrical wiring and liquid level monitoring, which greatly reduces the pipeline connection and installation space required outside the box, which is conducive to the compact integration and rapid installation of the entire system; The detachable top mounting cover integrates the discharge port and ventilation port, and also reserves or integrates the liquid level gauge installation position, and lays out the DC power terminal, so that all external interfaces are concentrated in one place, which is convenient for operation and maintenance; The pump body adopts a fully sealed design and acid and alkali resistant plastic material, which is suitable for corrosive environments; The key sewage suction and discharge ports and external connectors are made of copper alloy, which ensures the reliability and service life of long-term use; The bottom of the pump body can be fixed by an elastic mounting plate, ensuring smooth operation; The top mounting cover is detachable, which facilitates the inspection or replacement of the pump body.

[0014] Example

[0015] like Figure 1-3 The illustrated housing-integrated sewage pump includes: a sewage pump built-in motor 1, an adjustable mounting platform 2, a ventilation connector 3, and a discharge connector 4. The sewage pump built-in motor 1 adopts a fully sealed design and is made of acid and alkali resistant engineering plastics (such as PP or PVDF) to resist sewage corrosion. The lower end of the built-in motor 1 of the sewage pump is provided with a suction and discharge port 11, which is preferably made of copper alloy, which is strong and corrosion resistant. A mounting plate 12 can also be provided at the bottom of the built-in motor 1 of the sewage pump, which is connected to the inner bottom of the sewage tank by a fixing elastic bolt 13, which plays a role in auxiliary fixation and shock absorption. The adjustable mounting platform 2 includes an adjustable bolt 21 and a mounting cover 22. The built-in motor 1 of the sewage pump is connected to the lower part of the adjustable bolt 21 by a connecting plate 211. The mounting cover 22 is connected above the adjustable bolt 21 and fixed above the sewage tank. The height of the adjustable bolt 21 is adjusted according to the depth of the tank. The ventilation connector 3 is provided above the mounting cover 22. The discharge connector 4 is provided above the mounting cover 22 and an adjustable hose 41 is provided below it. The adjustable hose 41 is connected to the suction and discharge port 11.

[0016] like Figure 2-3 The illustrated tank-mounted sewage pump integrates a DC power terminal 221 on its mounting cover 22 for convenient and safe connection to a DC power source. Additionally, a level gauge 222 is integrated on the outer side of the tank, with its probe extending into the tank for real-time monitoring of the sewage level. When the level reaches a set high point, the level gauge 222 sends a signal to the control system, activating the built-in motor 1 of the sewage pump for discharge; when the level drops to a low point, the built-in motor 1 stops operating.

[0017] In this embodiment, both the ventilation connector 3 and the discharge connector 4 are fixedly installed on the mounting cover 22, and are preferably made of copper alloy. The ventilation connector 3 is used to connect the external ventilation hose 31 to maintain the air pressure balance inside and outside the box. Its hose inner diameter is usually 1 / 2 inch or 5 / 8 inch. The discharge connector 4 is used to connect the external discharge pipeline. A section of adjustable hose 41 is connected to its lower part. The other end of the adjustable hose 41 is connected to the sewage suction and discharge port 11 at the bottom of the sewage pump's built-in motor 1. This section of hose 41 has a certain length margin and flexibility, allowing the pump body to remain connected to it when adjusting the height. The discharge hose 42 has an inner diameter of usually 3 / 4 inch to meet the sewage discharge flow requirements.

[0018] During installation, first adjust the suspension height of the sewage pump's built-in motor 1 by rotating the adjustable bolt 21 according to the depth of the sewage tank. Then, insert the entire assembly from the top opening of the tank, fix the mounting cover 22 on the top of the tank, and connect the mounting plate 12 to the bottom of the tank using the fixing elastic bolt 13 (if necessary). Finally, on the outside of the top of the tank, connect the ventilation hose 31 to the ventilation connector 3, and the discharge hose 42 to the discharge connector 4. Connect the power cord to the DC terminal 221. The ventilation hose 31 can be selected as 1 / 2” or 5 / 8”, and the discharge hose 42 can be selected as 3 / 4”.
