[0020] The present application will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any form. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, a number of changes and improvements can be made. These all belong to the protection scope of the present application. EMBODIMENT
[0021] The present embodiment provides a self-filling filter, as shown in Figures 1-2 Figure 1, comprising a filter body 1 and a filter plate 2 installed on the filter body 1.
[0022] The filter body 1 is in a square structure in this embodiment, and an inlet 11 and an outlet 12 for liquid to enter and exit are arranged on the filter body 1. A flow channel 13 is arranged in the filter body 1 and communicates the inlet 11 and the outlet 12. A filter material bin 14 is further arranged on the filter body 1, and the filter material bin 14 is used to hold filter material used for filtering, which is granular activated carbon. The filter material bin 14 is provided with a discharge port in communication with the flow channel 13, and the discharge port is located close to the inlet 11.
[0023] The filter plate 2 can be in a square or circular shape, and the filter plate 2 is provided with a honeycomb structure filter channel in an array, i.e., the filter plate 2 is a honeycomb structure plate. The pore size of the filter channel is adapted to the particle diameter of the activated carbon, and the granular filter material of a corresponding size is stacked in the filter channel after entering the filter channel. The filter plate 2 is detachably inserted into the filter body 1, and one end of the filter plate 2 inserted into the filter body 1 passes through the flow channel 13, and the liquid entering from the inlet 11 flows through the filter plate 2 and then flows out from the outlet 12.
[0024] When the liquid enters from the inlet 11, the discharge port of the filter material bin 14 in communication with the flow channel 13 is opened, and the activated carbon in the filter material bin 14 automatically enters the filter channel of the filter plate 2 along with the flow of the liquid after flowing to the front end face of the filter plate 2. The filter plate 2 is stacked with activated carbon filter material to form a filter cake with filtering function, thereby forming a filter with good filtering performance. The self-filling filter provided in this embodiment forms a filter element by automatically filling the filter channel of the filter plate with filter material during the flow of the fluid, so that the filter element is simple and fast to form, and the dirt attached to the surface of the filter plate and the filter material that needs to be replaced can be easily removed by backwashing and other means, greatly improving the reuse rate of the filter plate and significantly reducing the overall cost of the filter. Embodiment
[0025] This embodiment 2 is formed on the basis of embodiment 1, and by installing multiple filter plates on the filter body and optimizing the structure of the flow channel, the filtering effect of the filter is effectively improved, and the miniaturization of the filter structure is facilitated. Specifically:
[0026] As Figures 1-2As shown, the filter plates 2 mounted on the filter body 1 are multiple, and in this embodiment, three filter plates 2 are taken as an example for description, and the three filter plates 2 are respectively denoted as a first filter plate 21, a second filter plate 22 and a third filter plate 23. The first filter plate 21, the second filter plate 22 and the third filter plate 23 are sequentially and spacedly arranged from one end to the other end of the filter body 1, and the pore diameters of the filter channels on the first filter plate 21, the second filter plate 22 and the third filter plate 23 are sequentially reduced. At this time, the activated carbon particles in the filter material bin 14 have three kinds of particle diameter sizes, which are respectively matched with the filter channel diameters of the first to third filter plates 23. During the flowing process of the granular activated carbon into the flow channel 13 from the discharge port of the filter material bin 14 along with the liquid, the large particles of activated carbon are firstly filled into the filter channel of the first filter plate 21, the activated carbon with the second particle diameter is filled into the filter channel of the second filter plate 22 after passing through the filter channel of the first filter plate 21, and the filter material with the third particle diameter is sequentially filled into the third filter plate 23 after passing through the first filter plate 21 and the second filter plate 22. The above structure design forms multiple filtering, and effectively improves the filtering effect. Of course, due to the accumulation of activated carbon in the filter channels of the first filter plate 21 and the second filter plate 22, a small amount of activated carbon particles with a diameter smaller than the matched diameter size exist in the filter channels.
[0027] Further, the inlet 11 and the outlet 12 are located on the same end surface of the filter body 1, and the flow channel 13 has a whole transversely arranged U-shaped structure design. The flow channel 13 includes a wave-shaped section 131 and a straight section 132, the wave-shaped section 131 is located at the upper portion and communicates with the inlet 11, and the straight section 132 is located at the lower portion and communicates with the outlet 12. A plurality of filter plates 2 are arranged at the wave crests and wave troughs of the wave-shaped section 131, as shown. Figure 1 The volume of the flow channel 13 at the position of the filter plate 2 is increased, so that the liquid surface can basically cover the surface of the filter plate 2, and the filtering efficiency is improved.
