Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment equipment, and in particular to a drainage mechanism that is easy to clean. Background Technology
[0002] In the pharmaceutical industry, filling machines are mainly used to accurately inject liquid medicine into containers. The filling head descends and uses a metering pump or liquid level control device to accurately inject the liquid medicine. At the same time, the system monitors data such as liquid level and flow rate in real time, and automatically stops and alarms when abnormalities occur.
[0003] During use, the filling machine needs to be cleaned regularly. The cleaning process involves multiple steps of cleaning and sterilization, including rinsing the pipes with purified water 3-5 times to remove residues, then sealing and disinfecting with 75% alcohol and testing the concentration. After cleaning, the transparency, pH value and cleanliness of the cleaning solution and the internal cleanliness of the equipment must be visually inspected. During the process, it is strictly forbidden to use hard objects to scrape or disassemble parts without authorization to ensure compliance with pharmaceutical hygiene standards.
[0004] During the cleaning process, the cleaning water needs sufficient pressure to flush the equipment container and remove impurities. These impurities cannot be directly discharged into the sewage pipe, so a filter device is installed on the drain pipe. However, to prevent the water used to clean the equipment from splashing onto the ground or other equipment due to high pressure, the filter device is usually installed inside the drain pipe. However, the impurities intercepted by the filter device are not easy to remove from the pipe, making it difficult for personnel to handle them. Utility Model Content
[0005] The main purpose of this utility model is to provide a drainage mechanism that is easy to clean. After cleaning water is injected into the third pipe, the cleaning water will flow into the second pipe, thereby backwashing the filter component. This allows the impurities intercepted by the filter component to enter the discharge pipe with the water flow and finally fall into the filter cartridge. At this time, the filter cartridge can intercept impurities, and the cleaning water will pass through the filter cartridge and be discharged through the fifth pipe. The filter cartridge is easy to remove from the cartridge, making it convenient for personnel to clean the impurities.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] An easy-to-clean drainage mechanism includes a drain pipe comprising a first pipe, a second pipe, a third pipe, and a fourth pipe connected in sequence. A filter assembly is disposed inside the second pipe. A waste discharge pipe is connected to the second pipe, and a first valve is disposed on the waste discharge pipe. The mechanism also includes a cylinder located below the waste discharge pipe, a filter cartridge is disposed inside the cylinder, and a fifth pipe is connected to the cylinder.
[0008] Furthermore, the filter assembly includes several fixing blocks fixed to the inner side of the second pipe, and a filter screen is provided on one side of each fixing block, the filter screen being fixed to the fixing block by screws.
[0009] Furthermore, a second valve is installed on the first pipeline.
[0010] Furthermore, a flexible hose is connected to the discharge pipe, and the bottom of the flexible hose is located inside the filter cartridge.
[0011] Furthermore, a water inlet pipe is also connected to the third pipe.
[0012] Furthermore, a third valve is installed on the fourth pipeline.
[0013] Furthermore, the two ends of the second pipe are connected to the first pipe and the third pipe respectively via flanges.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] After cleaning water is injected into the third pipe of this utility model, the cleaning water will flow into the second pipe, thereby backwashing the filter component. This allows the impurities intercepted by the filter component to enter the discharge pipe along with the water flow and finally fall into the filter cartridge. At this time, the filter cartridge can intercept impurities, while the cleaning water will pass through the filter cartridge and be discharged through the fifth pipe. The filter cartridge is easy to remove from the cartridge, making it convenient for personnel to clean the impurities.
[0016] The filter screen of this utility model is fixed to the fixing block by screws. The screws are easy to install and remove, which makes it convenient for personnel to install and remove the filter screen.
[0017] The second pipe of this invention can be detached from the first and third pipes, thereby facilitating personnel to clean or replace the filter screen.
[0018] The bottom of the hose of this invention is located inside the filter cartridge, so that the water discharged from the waste pipe can enter the filter cartridge through the hose, avoiding splashing of cleaning water during transportation. In addition, the hose is easy to deform and will not hinder personnel from removing the filter cartridge from the cartridge. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1-4 As shown, an easy-to-clean drainage mechanism includes a drain pipe 1, which includes a first pipe 101, a second pipe 102, a third pipe 103, and a fourth pipe 104 connected in sequence. A filter assembly 4 is provided inside the second pipe 102, and a waste discharge pipe 11 is connected to the second pipe 102. A first valve 5 is provided on the waste discharge pipe 11. The mechanism also includes a cylinder 8 located below the waste discharge pipe 11, a filter cartridge 7 is provided inside the cylinder 8, and a fifth pipe 9 is connected to the cylinder 8.
[0026] In this embodiment, such as Figure 1 As shown, the fourth pipe 104 connects to the workshop's sewage pipe, and the first pipe 101 connects to the equipment's sewage pipe, such as a filling machine. During the process of sewage entering the drain pipe 1 through the first pipe 101, the filter assembly 4 can intercept impurities in the sewage, preventing impurities from entering the workshop's sewage pipe and causing blockage. After the sewage is completely discharged, personnel can open the first valve 5 and inject cleaning water into the third pipe 103 using the workshop's water supply pipe. At this time, the cleaning water will flow into the second pipe 102, thereby causing the cleaning water to backwash the filter assembly 4. This allows the impurities intercepted by the filter assembly 4 to enter the waste discharge pipe 11 along with the water flow and finally fall into the filter cartridge 7. At this time, the filter cartridge 7 can intercept impurities, and the cleaning water will pass through the filter cartridge 7 and be discharged through the fifth pipe 9. The filter cartridge 7 is easy to remove from the cylinder 8, making it convenient for personnel to clean the impurities.
[0027] When backwashing the filter screen 401, the flow rate of the cleaning water should be less than the flow rate of the sewage discharge to ensure that the cleaning water does not splash out of the filter cartridge 7.
[0028] Among them, such as Figure 3 and Figure 4As shown, the filter assembly 4 includes several fixing blocks 402 fixed on the inner side of the second pipe 102. A filter screen 401 is provided on one side of the fixing block 402. The filter screen 401 is fixed to the fixing block 402 by screws 403. Several fixing blocks 402 are located on the same circumference, and the screws 403 are easy to disassemble and assemble, thereby facilitating personnel to disassemble and assemble the filter screen 401.
[0029] Among them, such as Figure 1 As shown, a second valve 10 is installed on the first pipe 101. When cleaning water is injected into the third pipe 103 using the workshop's water supply pipe, the second valve 10 should be closed to prevent the cleaning water from flowing out of the first pipe 101. Furthermore, an inlet pipe 2 is also connected to the third pipe 103. Therefore, the workshop's water supply pipe can be fixedly connected to the inlet pipe 2, thereby injecting cleaning water into the third pipe 103 through the inlet pipe 2, which in turn allows the cleaning water to enter the second pipe 102 to rinse the filter screen 401. Additionally, a third valve 3 is installed on the fourth pipe 104. When cleaning water enters the third pipe 103 through the inlet pipe 2, the third valve 3 should be closed to ensure that the cleaning water enters the second pipe 102.
[0030] like Figure 1 As shown, the two ends of the second pipe 102 are connected to the first pipe 101 and the third pipe 103 respectively via flanges. Therefore, the second pipe 102 can be detached from the first pipe 101 and the third pipe 103, which facilitates personnel to clean or replace the filter screen 401.
[0031] Among them, such as Figure 1 As shown, a hose 6 is connected to the discharge pipe 11, and the bottom of the hose 6 is located inside the filter cartridge 7, so that the water discharged from the discharge pipe 11 can enter the filter cartridge 7 through the hose 6, avoiding splashing of the cleaning water during the transportation process. In addition, the hose 6 is easy to deform and will not hinder the personnel from taking the filter cartridge 7 out of the cylinder 8.
[0032] Working principle: First, the fourth pipe 104 connects to the workshop's sewage pipe, the first pipe 101 connects to the equipment's sewage pipe, and then the inlet pipe 2 connects to the workshop's cleaning water supply pipe. When the equipment discharges sewage, the sewage will pass through the first pipe 101, the second pipe 102, the third pipe 103, and the fourth pipe 104 in sequence, and finally be discharged into the workshop's sewage pipe. During this process, the filter screen 401 can intercept impurities in the sewage, preventing the sewage pipe from becoming clogged due to impurities entering it. After the sewage is completely discharged, personnel will open the second valve. Door 10 and third valve 3 are closed, and first valve 5 is opened. At this time, the water supply pipe of the workshop injects cleaning water into the third pipe 103, so that the cleaning water enters the second pipe 102 and backwashes the filter screen 401. This allows the impurities intercepted by the filter assembly 4 to enter the discharge pipe 11 along with the water flow and finally fall into the filter cartridge 7. At this time, the filter cartridge 7 can intercept impurities, and the cleaning water will pass through the filter cartridge 7 and be discharged through the fifth pipe 9. The filter cartridge 7 is easy to remove from the cylinder 8, which makes it easy for personnel to clean the impurities.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
