Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to multi-media filters. Background Technology

[0002] With economic development and population growth, water shortages and water pollution are becoming increasingly serious, and people have higher and higher requirements for water quality. Whether in industrial production, municipal water supply or sewage treatment and reuse, effective water treatment technologies are needed to remove impurities, suspended solids, colloids and other pollutants from the water in order to meet different water needs.

[0003] Add the water to be filtered into a tank containing multiple filter layers. Let the water flow from the top to the bottom of the tank. After the water is filtered, drain it from the bottom of the tank.

[0004] Existing multi-media filters have fewer layers for water filtration, making it difficult to completely filter impurities in the water. They also lack the function of backwashing each filter layer individually. Therefore, a multi-media filter is proposed. Utility Model Content

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a multi-media filter, including a tank 1, an opening and closing mechanism 2 on the outside of the tank 1, and a filtering mechanism 3 in the inner cavity of the tank 1.

[0029] The opening and closing mechanism 2 includes a multi-port pipe 201 fixedly installed on the outside of the tank body 1. Each of the multiple output ends of the multi-port pipe 201 is fixedly installed with a connecting pipe 203. The inner cavity of the connecting pipe 203 is provided with a flap 209. An air inlet pipe 202 is fixedly connected to the outer surface of the multi-port pipe 201.

[0030] Specifically, the other end of the connecting pipe 203 is fixedly connected to the tank 1, the high-pressure gas is connected to the air inlet pipe 202, and water is introduced into the multi-port pipe 201. By controlling the opening and closing of the flaps 209 at the multiple ports of the multi-port pipe 201, each filter layer can be backwashed without interference.

[0031] A fixing plate 204 is fixedly installed on one side of the connecting pipe 203, and a telescopic cylinder 205 is provided on one side of the fixing plate 204. A toothed rack 206 is fixedly installed on the output end of the telescopic cylinder 205.

[0032] Specifically, the telescopic cylinder 205 is controlled to move forward, thereby indirectly controlling the flip plate 209 to flip.

[0033] A fixing block 207 is symmetrically arranged on one side of the fixing plate 204, and a rotating shaft 208 is rotatably connected to the inner cavity of the connecting pipe 203. A gear 210 is fixedly installed on one side of the rotating shaft 208.

[0034] Specifically, the fixed block 207 ensures the stable movement of the toothed rack 206. During the movement of the toothed rack 206, it drives the gear 210 to rotate around the rotating shaft 208, thereby driving the rotating shaft 208 to rotate. The rotating shaft 208 drives the flap 209 to rotate in the inner cavity of the connecting pipe 203, controlling the opening and closing of several connecting pipes 203.

[0035] The fixing block 207 is located on both sides of the toothed rack 206, the flap 209 is fixedly sleeved on the outside of the rotating shaft 208, and the gear 210 is meshed with the toothed rack 206.

[0036] Furthermore, the operation of the telescopic cylinder 205 is controlled. The output end of the telescopic cylinder 205 drives the toothed rack 206 to move. The toothed rack 206 drives the gear 210 to rotate, thereby driving the rotating shaft 208 to rotate in the connecting pipe 203. The rotating shaft 208 drives the flap 209 to rotate. The opening and closing of the flap 209 in the connecting pipe 203 is controlled. After the flap 209 that needs to be opened is opened, the high-pressure air pipe is inserted into the air inlet pipe 202. When water is injected into the multi-port pipe 201, the gas is sent into each filter layer in the tank 1. Under the action of gas and high-pressure water flow, the filter layer is cleaned.

[0037] Example 2

[0038] Reference Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a filter mechanism 3 capable of filtering water.

[0039] The filter mechanism 3 includes an inlet pipe 301 fixedly installed on the top of the tank 1, and an outlet pipe 302 fixedly installed at the bottom of the tank 1.

[0040] Specifically, water is added to tank 1 through inlet pipe 301, filtered through tank 1, and finally discharged from outlet pipe 302 for use.

[0041] The inner cavity of tank 1 is provided with a gravel layer 303, a quartz sand layer 304, an activated carbon layer 305 and an anthracite coal layer 306 arranged from bottom to top, and each layer is laid with the same thickness.

[0042] Specifically, under the action of the inlet pipe 301, water is injected into the top of the tank 1, and passes through the anthracite coal layer 306, the activated carbon layer 305, the quartz sand layer 304 and the gravel layer 303 in sequence. Finally, the filtered water is discharged from the outlet pipe 302.

[0043] The connecting pipe 203 is connected to the tank 1, and the connection point is located at the bottom of each filter layer.

[0044] Furthermore, the inlet pipe 301 is connected to the water supply pipe, and the water to be filtered is injected into the tank 1 through the inlet pipe 301. At this time, the water will pass through the anthracite layer 306, the activated carbon layer 305, the quartz sand layer 304 and the gravel layer 303 from top to bottom, and undergo multiple filtrations. Finally, the filtered water is discharged from the outlet pipe 302. The outlet pipe 302 is connected to the required location to use the filtered water.

[0045] Working principle: Connect the inlet pipe 301 to the water supply pipe. Water to be filtered is injected into tank 1 through the inlet pipe 301. The water passes through the anthracite layer 306, activated carbon layer 305, quartz sand layer 304, and gravel layer 303 from top to bottom, undergoing multiple filtrations. Finally, the filtered water is discharged from the outlet pipe 302. Connect the outlet pipe 302 to the desired location to use the filtered water. After a period of use, close the outlet pipe 302 and disconnect the water pipe connected to the inlet pipe 301. Connect the multi-port pipe 201 to the high-pressure water pipe, and insert the air inlet pipe 202 into the high-pressure air pipe. If backwashing of the anthracite layer 306 is required, flip the flap 209 in the connecting pipe 203 at the bottom of the anthracite layer 306. To open the flap 209, control the operation of the telescopic cylinder 205. The output end of the telescopic cylinder 205 drives the toothed rack 20. 6. Moving downwards, the toothed rack 206 drives the gear 210 to rotate, thereby driving the rotating shaft 208 to rotate in the connecting pipe 203. The rotating shaft 208 drives the flap 209 to rotate, controlling the flap 209 to open in the connecting pipe 203, allowing high-pressure water and high-pressure gas to rush into the bottom of the anthracite coal layer 306. Under the action of the bubbles, the impurities filtered by the anthracite coal layer 306 collide, and under the action of the high-pressure water, the impurities are flushed upwards. Finally, the impurities are flushed out from the water inlet pipe 301. If it is necessary to backwash the activated carbon layer 305, the principle is the same as above. Only the flap 209 in the connecting pipe 203 at the bottom of the activated carbon layer 305 is opened to flip it. The quartz sand layer 304 and gravel layer 303 are the same as above. Each filter layer is backwashed. The filter layers in the tank 1 filter impurities from top to bottom in descending order of size. Thus, during the backwashing process, the backwashing of the lower layer will not fail due to the backwashing of the upper layer, until the backwashing is completed.

[0046] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
