Description

Technical Field

[0001] This utility model belongs to the field of sewage discharge technology, specifically a compressor-driven pressurized sewage discharge device. Background Technology

[0002] A compressor is a mechanical device used to increase gas pressure. It is commonly used in many industrial and daily applications. By reducing the volume of gas and increasing its pressure, it enables the gas to be used in various jobs that require high-pressure gas, such as gas supply, refrigeration, air conditioning, and pneumatic tools. It plays a very important role in our industrial and daily life, and its maintenance and upkeep are crucial. During the air compression process, the moisture in the air will condense into water during the cooling process. If the condensate is not discharged in time, it may accumulate inside or outside the compressor, forming water stains or moisture, which may cause corrosion or rust to the equipment.

[0003] The compressor has a high internal pressure during the compression process. The condensate in the compressor cavity is usually discharged manually by using the internal pressure of the compressor. However, when discharging manually, the high internal pressure of the compressor can cause damage to the hands if not operated properly. Therefore, it is necessary to improve the method. Utility Model Content

[0004] To address the problem mentioned in the background art that improper operation can cause damage to the hands when high-pressure condensate is discharged, this utility model provides a compressor pressurized sewage discharge device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compressor pressurized sewage discharge device, comprising a compressor body, a discharge pipe fixedly installed at the bottom of the compressor body, a movable component provided in the inner cavity of the discharge pipe, a one-way valve fixedly connected to the end of the movable component away from the discharge pipe, the movable component including a connecting column, a limit block fixedly installed at the end of the connecting column near the discharge pipe, a limit groove opened at the lower end of the discharge pipe, and the limit block and the limit groove being movably connected, and a tension spring fixedly installed between the limit block and the discharge pipe.

[0006] Preferably, a connecting pipe is fixedly installed at the lower end of the one-way valve, an installation block is fixedly installed at the lower end of the connecting column near the one-way valve, a fixing block is fixedly installed in the middle of the outer wall of the connecting pipe, and a spring is fixedly installed between the fixing block and the installation block.

[0007] Preferably, a groove is provided in the middle of the inner cavity of the connecting tube, and a rubber ring is provided at the top of the connecting post near one end of the connecting tube.

[0008] Preferably, a rubber ring is provided at the top of the end of the connecting post near the pressure relief pipe, and the top of the connecting post is higher than the position where the pressure relief pipe has a limiting groove.

[0009] Preferably, the end of the one-way valve away from the connecting pipe is fixedly connected to the compressor body, and the inner wall of the limiting groove is smooth.

[0010] Preferably, the connecting column is made of stainless steel, and the tension spring is installed in the limiting groove.

[0011] Preferably, the end of the connecting column near the one-way valve is lower than the end of the connecting column near the pressure relief pipe, and the mounting position of the fixing block is higher than the position of the end of the connecting column near the one-way valve.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes the cooperation of movable components and a one-way valve. The pressure inside the compressor body compresses the connecting column. After the connecting column moves a certain distance, the air pressure inside the compressor body is released. The connecting column continues to move downwards until it is close to the one-way valve and moves out of the connecting pipe. The pressure inside the connecting column decreases, and condensate is discharged from the one-way valve. The pressure inside the compressor body gradually decreases, and the tension spring and spring drive the connecting column to reset. The condensate discharge process does not require manual operation, thus achieving the effect of not causing hand injury during condensate discharge. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, this utility model provides a compressor pressurized sewage discharge device, including a compressor body 1. A discharge pipe 2 is fixedly installed at the bottom of the compressor body 1. A movable component 3 is provided in the inner cavity of the discharge pipe 2. A one-way valve 4 is fixedly connected to the end of the movable component 3 away from the discharge pipe 2. The movable component 3 includes a connecting column 31. A limiting block 32 is fixedly installed at the end of the connecting column 31 near the discharge pipe 2. A limiting groove is opened at the lower end of the discharge pipe 2, and the limiting block 32 and the limiting groove are movably connected. A tension spring 33 is fixedly installed between the limiting block 32 and the discharge pipe 2.

[0021] The above solution works as follows: through the cooperation of the pressure relief pipe 2 and the movable component 3, when the pressure inside the compressor body 1 reaches a certain value, the pressure value inside the compressor body 1 squeezes the connecting column 31, causing the connecting column 31 to move downward. After the connecting column 31 moves a certain distance, the air pressure inside the compressor body 1 is discharged from the limiting groove opened by the pressure relief pipe 2. The connecting column 31 continues to move downward until it moves out of the connecting column 31 near the one-way valve 4. The pressure inside the connecting column 31 decreases, and the condensate is discharged from the one-way valve 4 to the sewage tank at the lower end of the condensate. This eliminates the need for manual operation during the condensate discharge process, achieving the effect of not causing hand injury when discharging condensate.

[0022] like Figure 3 and Figure 4 As shown, a connecting pipe 34 is fixedly installed at the lower end of the one-way valve 4, and an mounting block 36 is fixedly installed at the lower end of the connecting column 31 near the one-way valve 4. A fixing block 35 is fixedly installed in the middle of the outer wall of the connecting pipe 34. A spring 37 is fixedly installed between the fixing block 35 and the mounting block 36. The connecting column 31 is made of stainless steel, and the tension spring 33 is installed in the limiting groove. The end of the connecting column 31 near the one-way valve 4 is lower than the end of the connecting column 31 near the pressure relief pipe 2. The mounting position of the fixing block 35 is higher than the position of the end of the connecting column 31 near the one-way valve 4.

[0023] The above solution involves a fixed connection between the connecting pipe 34 and the one-way valve 4, securing the right end of the movable component 3. This allows for better drainage of condensate. After drainage, the spring 37 resets the connecting column 31 and the mounting block 36, ensuring good airtightness of the connecting pipe 34. No leakage occurs when condensate drainage is not in progress. The connecting column 31 is made of stainless steel, which offers excellent corrosion resistance, hardness, and wear resistance, enabling it to withstand harsh environments for extended periods. The stainless steel surface is smooth and easy to clean, and it will not cause any harm to the human body or the environment. The design of the end of the connecting column 31 near the one-way valve 4 being lower than the end of the connecting column 31 near the pressure relief pipe 2 allows the connecting column 31 near the one-way valve 4 to be quickly removed from the connecting pipe 34, thus allowing more time for condensate drainage. The installation position of the fixing block 35 is higher than the end of the connecting column 31 near the one-way valve 4, so that when the spring 37 drives the connecting column 31 to reset, the connecting column 31 can be engaged with the groove to form good airtightness.

[0024] like Figure 3 and Figure 4 As shown, a groove is provided in the middle of the inner cavity of the connecting pipe 34, a rubber ring is provided at the top of the connecting column 31 near the end of the connecting pipe 34, a rubber ring is provided at the top of the connecting column 31 near the end of the pressure discharge pipe 2, and the top of the connecting column 31 is higher than the position where the pressure discharge pipe 2 opens the limiting groove. The end of the one-way valve 4 away from the connecting pipe 34 is fixedly connected to the compressor body 1, and the inner wall of the limiting groove is smooth.

[0025] The above solution employs the following: through the cooperation of connecting pipe 34 and connecting column 31, the opening of the groove, and the cooperation of the rubber ring, the connecting pipe 34 achieves better sealing when condensate wastewater is not discharged. The design of the rubber ring at the top of the connecting column 31 ensures better airtightness when the pressure inside the compressor body 1 is not high enough to allow the connecting column 31 to move downwards, thus preventing air leakage from the compressor body 1. The top of the connecting column 31 is positioned higher than the position of the limiting groove on the discharge pipe 2, ensuring better airtightness and preventing air leakage when the pressure in the compressor body 1 is low. The smooth inner wall of the limiting groove reduces friction when the limiting block 32 moves within the groove, thereby reducing resistance when the connecting column 31 moves.

[0026] Working principle and usage process of this utility model:

[0027] When the pressure inside the compressor body 1 reaches a certain value, the pressure inside the compressor body 1 squeezes the connecting column 31, causing the connecting column 31 to move downwards. After the connecting column 31 moves a certain distance, the air pressure inside the compressor body 1 is discharged from the limiting groove opened in the discharge pipe 2, causing the rubber ring of the connecting column 31 near the top of the one-way valve 4 to disengage from the groove. The connecting column 31 continues to move downwards until the connecting column 31 near the one-way valve 4 is removed from the connecting pipe 34. The pressure inside the connecting column 31 decreases, and the condensate is discharged from the one-way valve 4, through the connecting pipe 34, and discharged into the wastewater tank at the lower end of the condensate collection point. After a period of time, the pressure inside the compressor body 1 gradually decreases, and the tension spring 33 and the spring 37 drive the connecting column 31 to reset, so that the top of one end of the connecting column 31 is higher than the position of the limiting groove of the discharge pipe 2 and the rubber ring of the other end is engaged with the groove, thus completing the reset. The condensate discharge process does not require manual operation, achieving the effect of not causing hand injury during condensate discharge.
