Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtration, in particular to a landscape garden sewage filtration circulation device. Background Art

[0002] Ecological garden refers to a garden green space system built under the guidance of ecological principles. When shaping the ecological garden landscape, water curtains or waterfalls are often used to increase the ecological atmosphere of the garden. As a result, a large amount of landscape sewage is generated, which flows into the sewage pipe together with rainwater, causing a huge waste of water resources. Therefore, landscape sewage filtration and circulation equipment is often installed for recycling. The existing landscape sewage filtration and circulation equipment mainly achieves the filtration and recycling of landscape sewage through the cooperation of filter boxes, bioreactors and circulation pumps. The bioreactor is a sewage biological treatment system with biofilm as the purification body. It gives full play to the characteristics of high biological density, strong pollution resistance, low power consumption, stable operation and easy maintenance of biofilm reactors such as anaerobic biological filters and contact oxidation beds. The entire landscape sewage filtration and circulation equipment is buried under the surface, and greening can be carried out on it, making the environment beautiful.

[0003] Some existing landscape sewage filtration circulation devices are found to be insufficient during use. The existing devices are provided with a mechanism for filtering and collecting sewage impurities, and when cleaning certain collected impurities, the overall water flow needs to be disconnected to clean the impurities. This operation will temporarily disconnect the sewage filtration cycle process and affect the efficiency of the filtration cycle. For this reason, we design a landscape garden sewage filtration circulation device to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a landscape garden sewage filtering and circulation device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

There is a three-way valve, one end of the external water inlet pipe is connected to the water inlet end of the three-way valve, one water outlet end of the three-way valve is connected to the first internal water inlet pipe, and the other water outlet end is connected to the first connecting pipe, the other end of the first connecting pipe is connected to the second connecting pipe at the rear side, the other end of the second connecting pipe is connected to the second internal water inlet pipe at the bottom, the second internal water outlet pipe is connected to the third connecting pipe at the top, the other end of the third connecting pipe is connected to the external water pipe, a one-way valve is provided on the external water pipe and at a position on the left side of the third connecting pipe, and transparent glass is provided on the front side of the outer surfaces of the first and second sewage collecting sleeves.

[0007] As a preferred solution of the utility model: a first filter screen is provided in the first inner water outlet pipe, and a second filter screen is provided in the second inner water outlet pipe.

[0008] As a further preferred solution of the utility model: the upper parts of the outer surfaces of the first sewage collecting sleeve and the second sewage collecting sleeve are provided with external threads, and the lower parts of the inner surfaces of the first sewage discharge pipe and the second sewage discharge pipe are respectively provided with internal threads matched with the corresponding external threads.

[0009] As a further preferred solution of the present invention: the first sewage collecting sleeve and the second sewage collecting sleeve are both provided with a collecting cavity, and the top of the collecting cavity is designed to be open.

[0010] As a further preferred solution of the utility model: the left and right ends of the top of the three-way valve are provided with fixing plates, the top of the fixing plates is fixedly connected to the top wall of the box body, and the handle on the top of the three-way valve is arranged on the top of the box body.

[0011] Compared with the prior art, the utility model has the following beneficial effects: when the device is used, sewage enters the box body from the external water inlet pipe, and flows into the first sewage pipe from the first internal water inlet pipe, and is filtered by the first filter screen, and is discharged through the first internal water outlet pipe and the external water pipe. When the staff finds that the water flow in the external water pipe is small, or observes through the transparent glass that there are many impurities gathered in the first sewage collecting sleeve, the staff can rotate the handle to control the direction of the water flow, that is, control the water flow to enter the first connecting pipe, and the sewage then enters the second sewage pipe through the second connecting pipe and the second internal water inlet pipe, and is filtered by the second filter screen. The water then enters the external water pipe again through the second internal water outlet pipe and the third connecting pipe, and is discharged through the external water pipe. The setting of the one-way valve can prevent the water flow from flowing back into the first sewage pipe at this time. At the same time, the staff disassembles the first sewage collecting sleeve at the bottom of the first sewage pipe and cleans the inside of the first sewage collecting sleeve. The whole process will not affect the sewage filtration cycle at all, ensuring the efficiency of the sewage filtration operation, which is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS
