Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a sewage lifting box interface design. Background Technology
[0002] A sewage lift tank is a device used to collect and lift sewage. It plays an important role in some scenarios where gravity-fed drainage is not possible. When sewage flows into the sewage lift tank from various drainage devices, a liquid level sensor is installed in the tank to monitor the water level. When the water level rises to the set upper limit, the sensor will send a signal to start the sewage lift pump. The sewage lift pump lifts the sewage in the tank to the designated drainage system through the drainage pipe.
[0003] However, existing technologies still have shortcomings. For example, the sewage lifting device with patent number CN202321857328.6 includes a tank, a sewage outlet is fixedly connected to one side of the tank, a tank cover is movably connected to the top of the tank, a threaded sleeve is fixedly connected to one side of the top of the tank cover, and an installation groove is fixedly connected to the other side of the top of the tank cover. The sewage outlet is connected to the inside of the tank, and the installation groove is connected to the inside of the tank. The sewage inlet pipe and the drainage device in this device are connected by a single pipe, which cannot simultaneously adapt to the connection through flange interfaces or PVC smooth pipes or flexible hose joints, resulting in extremely poor practicality.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Example 1: Reference Figures 1-3 A sewage lifting box interface design includes: a conveying mechanism, a box body 2, an inlet pipe 2.1, and an exhaust pipe 2.2. The conveying mechanism is connected to the box body 2. The input end of the conveying mechanism is connected to one end of the inlet pipe 2.1. The other end of the inlet pipe 2.1 has a thread on its side wall. The exhaust pipe 2.2 is connected to one end of the box body 2. The other end of the exhaust pipe 2.2 is located away from the box body 2. The other end of the exhaust pipe 2.2 has a second thread on its side wall.
[0024] The principles and beneficial effects of the above scheme are as follows:
[0025] Before the device starts working, it connects to the other end of the inlet pipe 2.1 via a pipe. Since the other end of the inlet pipe 2.1 has threads on its side wall, it can be directly threaded to the other end of the inlet pipe 2.1 when the other end of the pipe is a PVC smooth pipe or hose connector, it can be directly fitted onto the threads. Since the threads themselves have multiple equidistant helical grooves in their longitudinal direction, the inner wall of the end of the PVC smooth pipe or hose connector can be firmly locked onto one end of the inlet pipe 2.1. Then, the conveying mechanism is started, and the sewage in the pipe enters into the inlet pipe 2.1 and is finally output through the conveying mechanism. While the sewage is being conveyed, the exhaust pipe 2.2 is used to discharge the gas in the tank 2. Since the exhaust pipe 2.2 has threads, it can also be connected to a flange interface or a gas conveying pipe made of PVC smooth pipe or hose.
[0026] The device, by setting threads and thread 2, allows the water inlet pipe 2.1 and the exhaust pipe 2.2 to be connected to the flange interface or PVC smooth pipe or hose, which greatly increases the practicality of the device and its adaptability under different working conditions.
[0027] The addition of threaded and second threaded connections increases the stability of the device when connected to pipelines and gas transmission pipelines.
[0028] Example 2: Reference Figures 1-3 The conveying mechanism includes a water pump 1, which is connected to the housing 2, and the input end of the water pump 1 is connected to one end of the water inlet pipe 2.1.
[0029] The housing 2 is connected to a pipe 5. One end of the pipe 5 is connected to the output end of the water pump 1, and the other end of the pipe 5 is located away from the housing 2.
[0030] The end of the auxiliary pipe is connected to the pipe 5, and the other end of the auxiliary pipe is located away from the box 2.
[0031] A check valve is installed in the pipeline 5, and the check valve is located between the output end of the water pump 1 and the end of the auxiliary pipeline.
[0032] The principles and beneficial effects of the above scheme are as follows:
[0033] When the device starts transporting sewage, pump 1 is started. Sewage enters through the pipeline to the other end of inlet pipe 2.1, and is then transported by pump 1 into pipe 5. Finally, the sewage is transported to the sewage discharge system. To prevent damage to pipe 5 due to excessive water pressure during sewage transport, an auxiliary pipe is connected to pipe 5 to avoid excessive pressure during device operation. At the same time, a check valve is installed in pipe 5. The check valve is located between the output end of pump 1 and the end of the auxiliary pipe to prevent the output sewage from flowing back and remaining inside the device's pipe structure, thus preventing corrosion of the device.
[0034] Example 3: Reference Figures 1-3 The other end of the water inlet pipe 2.1 is provided with a rounded corner between it and its side wall.
[0035] The principles and beneficial effects of the above scheme are as follows:
[0036] Because the other end of the water inlet pipe 2.1 has a rounded corner between it and its side wall, the other end of the water inlet pipe 2.1 can prevent damage to the inside of the pipe when the device is connected to the pipe.
[0037] Example 4: Reference Figures 1-3 The other end of the exhaust pipe 2.2 is provided with a rounded corner between it and its side wall.
[0038] The principles and beneficial effects of the above scheme are as follows:
[0039] The other end of the exhaust pipe 2.2 is provided with a rounded corner between it and its side wall, which can also prevent the other end of the exhaust pipe 2.2 from damaging the inside of the gas transmission pipeline during the installation of the gas transmission pipeline.
[0040] Example 5: Reference Figures 1-3 The water inlet pipe 2.1 has multiple circular holes 3 through its side wall. A rod 4 is slidably connected inside the circular holes 3. The end of the rod 4, which is placed outside the side wall of the water inlet pipe 2.1, is connected to the end face of the extrusion block 6. The end face of the extrusion block 6 is connected to the side wall of the water inlet pipe 2.1 by a spring 8. The other end face of the extrusion block 6 is an arc-shaped surface. The center of the arc-shaped surface is concentric with the center of the water inlet pipe 2.1. A thread 7 is provided on the arc-shaped surface.
[0041] The principles and beneficial effects of the above scheme are as follows:
[0042] When connecting the pipes, the pipe end first presses the arc-shaped surface of the extrusion block 6, the spring 8 is compressed, and the extrusion block 6 moves into the water inlet pipe 2.1 under the sliding connection between the insertion rod 4 and the round hole 3.
[0043] If the pipe joint has a flange interface, after the extrusion block 6 is extruded, rotate the flange interface. The internal thread of the flange interface is threaded to the thread line 7 on the arc surface until the internal thread of the flange interface is threaded to the thread of the inlet pipe 2.1 and then the rotation ends.
[0044] After the flange interface or PVC smooth pipe or hose joint is installed in place, under the elastic force of the spring 8 returning to its original position, the arc surface of the compression block 6 compresses the inner wall of the flange interface or PVC smooth pipe or hose joint to increase the stability of the inlet pipe 2.1 after it is connected to the pipeline. This prevents the pipeline from falling off the other end of the inlet pipe 2.1 due to vibrations caused by repeated starts of the device. Furthermore, it can increase the sealing performance of the pipeline when supplying sewage and prevent sewage leakage caused by the pipeline being offset relative to the axis of the inlet pipe 2.1.
[0045] Example 6: Reference Figures 1-3 The end of the insertion rod 4, which is placed inside the water inlet pipe 2.1, is connected to the end face of the extrusion block 9.
[0046] An inclined surface 10 is provided between the top surface of the extrusion block 2 9 and its other end surface, and the inclined surface 10 is set towards the rounded corner of the water inlet pipe 2.1.
[0047] The principles and beneficial effects of the above scheme are as follows:
[0048] Since the other end of the insertion rod 4 is connected to the extrusion block 9, when the device supplies sewage, the flowing sewage and the inclined surface 10 are in frictional contact. When the sewage flow rate is large and the flow velocity is fast, the friction force on the inclined surface 10 is greater, which further increases the pressure applied by the extrusion block 6 to the inner wall of the pipe. Therefore, the pipe can operate safely under higher water pressure.
[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
