Description

Technical Field

[0001] The utility model relates to the technical field of fertilizers, in particular to a UV disinfection device of a water-fertilizer integrated machine. Background Art

[0002] The integrated water-fertilizer machine is a fertilization device. Now we are vigorously promoting the cultivation of high-economic crops in greenhouses. Fertilizer is the main consumable material in greenhouse cultivation. In order to maximize the use of fertilizers, recycling fertilizers is a situation that we have to face. However, fertilizer water carries many pathogens and microorganisms, which can easily cause insect pests. Therefore, in order to recycle fertilizer water, it is necessary to disinfect the fertilizer water.

[0003] Since fertilizer water has a dark color and turbidity, the UV penetration rate is generally only 3-4mm, and the UV intensity of a general UV sterilizer lamp is very low. If the UV sterilization is not thorough, it will cause pests and diseases over a larger area, leading to a large amount of economic losses. Therefore, based on the above problems, a UV disinfection device for a water-fertilizer integrated machine is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a UV disinfection device for a water-fertilizer integrated machine to solve the problem that the existing UV disinfection device has a general disinfection effect on fertilizer water. If the ultraviolet sterilization is not thorough, it will cause pests and diseases over a larger area, resulting in a large amount of economic losses.

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

[0006] A UV disinfection device for a water-fertilizer integrated machine comprises a frame, a positioning frame is fixedly connected to the upper side of the frame, UV reactors are fixedly connected in the front and rear two groups of clamps of the positioning frame, the front and rear UV reactors are connected through a left-side connecting pipe, the right part of the rear curved surface of the rear UV reactor is connected to a shunt input pipe, the right part of the front curved surface of the front UV reactor is connected to a converging output pipe, a flow meter is installed at the left vertical pipe of the converging output pipe, the lower end of the left vertical pipe of the converging output pipe is connected to an output branch pipe, a pump body is installed on the upper side of the frame, a water pumping pipe is connected to the left side of the pump body, an output connecting pipe is connected to the right side of the pump body, a flow control valve is installed at the output connecting pipe, and a control cabinet is installed on the upper side of the frame.

[0007] Preferably, a group of four UV reactors equidistantly arranged vertically are fixedly connected in the rear clamp of the positioning frame, and a group of four membrane filters equidistantly arranged vertically are fixedly connected in the front clamp of the positioning frame. The membrane filters and UV reactors at the same height are connected through the left connecting pipe, the right part of the rear curved surface of the UV reactor is connected to the shunt input pipe, and the right part of the front curved surface of the membrane filter is connected to the converging output pipe.

[0008] Preferably, a low-pressure ultra-high-intensity UV lamp tube with a length of 220 cm and a diameter of 38 is provided inside the pipeline of the UV reactor. The UV reactor is horizontally arranged. The shunt input pipe is provided with four input connecting pipes, and the confluence output pipe is provided with four receiving connecting pipes.

[0009] Preferably, the output branch pipe is composed of an upper middle pipe and a lower bent branch pipe. The upper middle pipe of the output branch pipe is communicated with the lower end of the left vertical pipe of the confluence output pipe. A sampling valve is installed inside the upper middle pipe of the output branch pipe.

[0010] Preferably, the control cabinet is electrically connected to the pump body and the flow control valve, and the control cabinet is electrically connected to the low-pressure ultra-high-intensity UV lamp tube of the UV reactor.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, through the structures such as the pump body, the shunt input pipe, the confluence output pipe, the UV reactor, and the membrane filter, the two series-connected UV reactors can double the duration of the water path passing through the UV lamp to improve the sterilization efficiency. The appearance and connection methods of the UV reactor and the membrane filter are basically the same, which can achieve a replacement effect and can be applicable to equipment that requires both UV sterilization and membrane filtration at the same time. The membrane filter and the UV reactor are connected in series, so that the water path first passes through the UV reactor to decompose most of the acidic substances, and then flows into the membrane filter, which can protect the permeable membrane from being corroded by acidic substances and improve the service life of the membrane. And through the membrane filter, the suspended solids, colloids, bacteria, and viruses in the fertilizer water are removed, realizing that the UV disinfection device can fully sterilize and disinfect the fertilizer water used in the water and fertilizer integrated machine, enabling the fertilizer water to be recycled, and solving the problem that the existing UV disinfection device has a general disinfection effect on the fertilizer water. If the ultraviolet sterilization is not thorough, it will cause a larger area of plant diseases and insect pests, resulting in a large amount of economic losses. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] It should be noted that the terms used here are only for describing specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used here, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0019] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0020] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are usually based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0021] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0022] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

The upper middle pipe of the output branch pipe 7 is connected to the lower end of the left vertical pipe of the confluence output pipe 5. A sampling valve is installed inside the upper middle pipe of the output branch pipe 7. Through this setting, the sampling valve in the output branch pipe 7 can divide the sterilized fertilizer water into two types.
