Description

Technical Field

[0001] This utility model relates to the field of water filter technology, specifically a floating filter that is convenient to carry in vehicles and used for pumping water from lakes and ponds. Background Technology

[0002] In urban and rural areas dotted with lakes and ponds, sanitation sprinkler trucks and other water-using vehicles often need to pump water from these sources for purposes such as spraying to suppress dust and improve air quality. When pumping water from lakes and ponds, if only the small, simple mesh filter at the inlet of the suction hose is used, not only is the filtration area small and prone to clogging, but the suction height also needs to be manually controlled, otherwise, silt from the bottom of the lake may be sucked up.

[0003] Floating filters already exist, which combine a float and filter components, allowing them to float on the water's surface. This avoids sucking up silt from the lakebed and debris such as weeds and leaves from the surface. However, because the float is located outside the filter components, these filters take up a lot of space and are inconvenient to carry in vehicles. Summary of the Invention

[0004] In response to the technical problems mentioned in the background above, this utility model provides a compact floating filter that sets the buoyancy component inside the filter element. This not only takes up little space, but also allows for easy adjustment of the buoyancy magnitude and distribution, and the filter is easy to disassemble and clean.

[0005] Technical Solution: A compact floating filter includes a filter cylinder, which is a metal cylinder with filter holes; a rear cover is provided at the rear end of the filter cylinder, the center of which is machined with a large hole and welded to a connecting pipe on the outside; a channel seat is welded to the inner side of the rear cover, the channel seat is assembled from a rear top plate and four rear upright plates, the distance between the rear top plate and the rear cover separated by the rear upright plates provides an outlet flow channel, and a threaded hole is machined at the center of the rear top plate for connecting a connecting rod; the connecting rod is a slender rod with threads at both ends, used to connect several large and small floats. Installed inside the filter cylinder; the large float is shaped as a short, perforated cylinder with an outer diameter smaller than the inner diameter of the filter cylinder, and passes through the connecting rod to provide primary buoyancy; the small float is smaller than the large float and passes through the connecting rod to provide secondary buoyancy; a front partition is inserted into the front end of the connecting rod, the front partition being welded together from a front top plate, four front upright plates, and a small cylinder, used to separate the large float from a front cap; the front cap is located at the front end of the filter cylinder, passes through the connecting rod, and is tightened with the rear cap by a nut to seal the front and rear ends of the filter cylinder.

[0006] Furthermore, filter holes are machined on the front and rear end caps to increase the filter area.

[0007] Furthermore, the axial height of the large float is set to be an integer multiple of the axial height of the small float. By adjusting the number and installation position of the large and small floats, the height at which the filter floats in the water is set, and the buoyancy before and after the filter is adjusted to maintain horizontal balance.

[0008] Furthermore, an annular protrusion is provided on the inner outer edge of the front and rear plugs, which matches the inner diameter of the filter cylinder, for sealing and positioning of the front and rear plugs to prevent radial movement.

[0009] Furthermore, external threads are machined on the outside of the connecting tube for connecting the connector of the suction hose.

[0010] Compared with existing background technologies, the above-described at least one technical solution adopted in one or more embodiments of this specification can achieve the following beneficial effects: First, the buoyancy components are housed inside the filter cylinder, resulting in a compact overall structure that saves installation space. Second, by adjusting the number and installation position of the large and small floats, the filter's floating height in the water can be easily set, and the buoyancy before and after the filter can be adjusted to maintain horizontal balance. Finally, the filter can be disassembled by removing a single nut, facilitating the unclogging and cleaning of the filter components.

[0011] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit the present invention.

[0012] Other features and aspects of the present invention will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings. Attached Figure Description

Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0017] Furthermore, to better illustrate this utility model, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this utility model can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this utility model.

[0018] like Figures 1-7 As shown, a compact floating filter includes a filter cylinder 1, a rear plug 2, a channel seat 3, a connecting pipe 4, a front partition 5, a front plug 6, a connecting rod 7, a nut 10, and several large floats 8 and small floats 9.

[0019] like Figure 1 As shown, filter cylinder 1 is a metal cylinder with filter holes.

[0020] like Figure 1 and Figures 3-5As shown, a rear plug 2 is provided at the rear end of the filter cylinder 1. A large hole is machined in the center of the rear plug 2 and welded to a connecting pipe 4 on the outside. External threads are machined on the outside of the connecting pipe 4 for connecting the connector of the suction hose. A channel seat 3 is welded to the inside of the rear plug 2. The channel seat 3 is assembled from a rear top plate 301 and four rear upright plates 302. The distance between the rear top plate 301 and the rear plug 2 separated by the rear upright plates 302 provides an outlet flow channel. A threaded hole is machined in the center of the rear top plate 301 for connecting a connecting rod 7. The connecting rod 7 is a slender rod with threads machined at both ends, used to connect several large floats. 8 and small floats 9 are installed inside the filter cylinder 1; the large float 8 is made of foam plastic commonly used in the fishery industry, and is shaped as a short, perforated cylinder with an outer diameter smaller than the inner diameter of the filter cylinder 1. It is threaded onto the connecting rod 7 to provide the main buoyancy; the small float 9 is made of foam plastic commonly used in the fishery industry, and is smaller in size than the large float 8. It is threaded onto the connecting rod 7 to provide secondary buoyancy; the axial height of the large float 8 is set to be an integer multiple of the axial height of the small float 9. By adjusting the number and installation position of the large float 8 and the small float 9, the height at which the filter floats in the water is set, and the buoyancy before and after the filter is adjusted to maintain horizontal balance.

[0021] like Figure 1 and Figure 6 , Figure 7 As shown, a front partition 5 is inserted through the front end of the connecting rod 7. The front partition 5 is welded together from a front top plate 501, four front upright plates 502, and a small cylinder 503. It is used to separate the large float 8 from a front cover 6. The front cover 6 is set at the front end of the filter cylinder 1 and is inserted through the connecting rod 7. The front cover 6 and the rear cover 2 are tightened by a nut 10 to seal the front and rear ends of the filter cylinder 1.

[0022] like Figure 1 , Figure 3 and Figure 6 As shown, filter holes are machined on the front cover 6 and the rear cover 2 to increase the filter area; annular bosses are provided on the inner outer edges of the front cover 6 and the rear cover 2, which are matched with the inner diameter of the filter cylinder 1 and are used for sealing and positioning of the front cover 6 and the rear cover 2 to prevent radial movement.

[0023] like Figures 1-7 As shown, the specific method of using this utility model is as follows: Before use, select the number of large floats 8 and small floats 9 according to the required depth of the lake water source. For example, if the water source is deep, select fewer large floats 8 and more small floats 9 to reduce buoyancy, so that the filter has a deeper draft and increases the filtration area; if the water source is shallow, select more large floats 8 and fewer small floats 9 to increase buoyancy, so that the filter has a shallower draft and avoids sucking up the silt from the bottom of the lake.

[0024] When assembling the filter, first connect one end of the connecting rod 7 to the channel seat 3, and insert several large floats 8 and small floats 9 and the front spacer 5 into the other end. Then, seal the rear end cap 2 at the rear end of the filter cylinder 1, and then insert the front end cap 6 into the front part of the connecting rod 7 to seal the front end of the filter cylinder 1. Finally, tighten it with the nut 10.

[0025] When using the filter, simply connect the suction hose connector to the connecting pipe 4 and then place the filter into the water. During suction, the lake water passes through the filter cylinder 1, the front plug 6, and the rear plug 2 before entering the filter cylinder 1. Then, it passes through the flow channel of the channel seat 3 and the connecting pipe 4 before entering the suction hose.

[0026] When the filter is clogged and needs cleaning, or when it needs to be cleaned after a long period of disuse, simply loosen nut 10 to disassemble the various parts for easy cleaning of the filter holes of filter cartridge 1, rear plug 2, and front plug 6.
