filter

【Technical field】

The utility model relates to a filter, in particular to a filter used in an aquarium, a fish pond or a fish tank.

【Background technique】

We know that the filter used in fish farming mainly includes a filter tank, and a pile of sand is placed in the filter tank at this stage. When the filter is working, the sewage comes in from the upper part of the filter tank, and is adsorbed and filtered when it flows through the sand particles, and then flows back into the pool through the lower part of the tank for recycling or other purposes. Because the sand particles are heavy and piled up relatively densely, the dirt is basically adsorbed on the upper part of the sand layer, and the large dirt remains on the surface of the sand layer and is not easy to discharge. Therefore, the sand particles in the filter tank must be cleaned frequently, otherwise it will be damaged. Affect the filtering effect, which is not only difficult to clean, but also increases the work intensity and maintenance cost. At the same time, because the sand layer is relatively thick, it is easy to filter out the microorganisms in the water, so the microorganisms cannot flow back into the fish pond, which will inevitably affect the survival and growth of fish.

【Detailed ways】

The utility model relates to a filter, which includes a filter tank 1 with many colloidal particles placed in it, and the lower and upper parts of the filter tank 1 are respectively provided with water outlets and water inlets that can be connected with fish ponds or fish tanks. The water inlet pipe 3 and the water outlet pipe 4; the tail end of the water inlet pipe 3 and the front end of the water outlet pipe 4 are respectively provided with water distribution ports 31, 41, and several water distribution ports are arranged outside the water distribution port 31 of the water inlet pipe 3 The water that comes out from 31 forms the curved vane 5 of vortex; The bottom of described filtering tank 1 is provided with the sewage outlet 11 that discharges for larger dirt, and it is generally facing the bottom of vortex.

The filter tank 1 is a colloidal particle filter tank, which is a closed pressure vessel. The built-in colloidal particles are generally polyethylene particles (beads) that meet edible standards. Particles of different shapes and sizes can provide a huge surface area, thereby enabling The bacteria and dirt particles in the water are easily adsorbed on its surface, and after a period of use, a layer of biological layer will be formed on the surface of the colloidal particles quickly. The apertures of the water distribution ports 31, 41 are smaller than the colloidal particles to prevent the colloidal particles from being discharged from the water pipe. The working process of the utility model is as follows: the water pump in the fish pond is pumped into the water inlet pipe 3 in the filter tank 1 bottom and discharged into the tank by its water distribution port 31, and the curved blade 5 makes the water flow form a vortex. At this time, the larger The dirt is sucked into the vortex, and when the sewage outlet 11 is opened, the large dirt can be quickly discharged; while the smaller dirt and bacteria follow the sewage to flow upwards in the tank, they are captured by colloidal particles and adsorbed on the surface In this way, the final clean water enters the pipe through the outlet 41 of the water outlet pipe 4 and then flows back into the pool to realize the process of filtering and recycling the pool water. It can be seen that the large dirt is discharged from the sewage outlet, and the small dirt is completely absorbed by the colloidal particles without adhering to the microorganisms in the water. Therefore, the utility model has a good dirt filtering effect and can effectively retain the microorganisms in the water.

The water inlet pipe 3 is provided with a branch 32 connected to the air inlet pipe 6 (in this embodiment, the branch is arranged outside the filter cylinder for easy installation and maintenance), and the air inlet 61 of the air inlet pipe 6 is connected to the air inlet pipe 6. The pump 7 is connected, and an exhaust port 12 is arranged on the upper part of the filtering cylinder. The air inlet 61 is generally higher than the height of the filter cylinder, so that the water in the water inlet pipe can be prevented from flowing to the air pump; in addition, a one-way check valve can also be provided to prevent water from entering the air pump when the air pump is not working.

The filter usually also includes a multifunctional filter cylinder head 8 controlled by a changeover switch 81 thereon, and the filter is adjusted to complete a certain work by the function conversion of the filter cylinder head. The front end of the water inlet pipe 3 and the tail end of the water outlet pipe 4 are connected with the lower pipeline 82 and the upper pipeline 83 of the filter cylinder head 8 respectively; The water port is connected, and the sewage inlet 85 is connected with the drain of the fish pond or the fish tank by the water pump 9. In this embodiment, the filter cylinder head 8 is a cylinder head valve with six functions, which are respectively normal filtration, no filter circulation, direct drainage, filter cylinder cleaning, backwashing and closing. Also be provided with direct sewage outlet 86, also be provided with transparent observation mirror 87 near direct sewage outlet 86 in addition, so that observe whether sewage is clean.

When the changeover switch 81 beat the filter cylinder head 8 in the normal filtering state, its sewage inlet 85 and the lower pipeline 82 communicated, and its upper pipeline 83 communicated with the clean water outlet 84. So the water pump 9 pumps the sewage in the fish pond or fish tank and enters the water inlet pipe 3 after the sewage inlet 85 and the lower pipeline 82 of the filter tank head 8, and then discharges from the water inlet 31 of the water inlet pipe to generate eddy currents. At this time, the large dirt It is collected from the bottom of the vortex and discharged from the sewage outlet 11 at the bottom of the filter tank 1 when necessary; while the small dirt is absorbed and filtered by the colloidal particles when it follows the sewage to the outlet pipe 4, the clean water flows from the outlet of the outlet pipe 4 41 flows back in the fish pond or the fish tank through the water inlet of the fish pond after flowing to the upper pipeline 83 and the clean water outlet 84 of the filter cylinder head 8, and realizes the filtration process.

When the filter tank head 8 was in the non-filtered circulation gear, its sewage inlet 85 communicated with the clean water outlet 84, so the water coming in from the sewage inlet 85 of the filter tank head directly flowed back to the fish pond through the clean water outlet 84 but in the fish tank. This gear is generally used when treating fish water with some kind of medicine that does not pass through the filter tank.

When the filter cylinder head was in the direct drainage gear, its sewage inlet 85 communicated with the direct drainage sewage outlet 86. So the water coming in from the sewage inlet 85 of the filtering tank head is directly discharged to the sewer through the direct sewage outlet 86, and this function can be used for draining or changing the pool water.

When it is in the cleaning function of the filter tank, the flow direction of the water is the same as that of normal filtration, but the air pump needs to be started to clean the dirt on the colloidal particles. Together with the water in the water inlet pipe, it enters the filter tank through its water distribution port 31, and with the help of the blowing of the wind, the colloidal particles roll quickly in the tank, thereby cleaning the small dirt adsorbed on the surface of the colloidal particles come out. This function is used when the filter tank needs to be cleaned after being used for a period of time. Generally, it is enough to clean it 1-3 times a week. Trouble and hard work.

When it is in the function of backwashing (backwashing is opposite to the flow direction of water during normal filtration), the water is sequentially discharged from the sewage inlet 85, the upper pipeline 83, the water distribution port 41, the water distribution port 31, the lower pipeline 82, and the sewage directly. The water outlet 86 discharges the sewage in the tank. The backwash function is generally used in conjunction with the filter tank cleaning function above to further improve the cleaning effect of the colloidal particles, thereby ensuring the filtering effect for the next normal filtration.

The utility model usually controls the work of components such as water pumps and air pumps by controlling the electric box 10 . The filter can be used for water filtration in koi ponds, aquariums or glass fish tanks.
