Problems solved by technology

[0006] The above two disclosed technologies are both rotary microfilters. Although they can effectively remove pollutants, they still have high purchase costs and a large floor space. When using them, water needs to be introduced first and then discharged, so the efficiency is low. high energy consumption
In addition, the backwashing devices need to use high-pressure water pumps to supply water for flushing, which consumes a lot of water, and the cleaning effect is not ideal in actual use.

Embodiment 1

[0027] Such as Figure 1 to Figure 2 As described above, a crawler-type microfiltration machine includes a frame 2 arranged in a water tank 1 , and a cover 3 is provided on the upper end of the frame 2 .

[0028] The bottom is provided with a first support roller 21 and a second support roller 22, the top is provided with a third support roller 23, the middle part is provided with a fourth support roller 24 and a fifth support roller 25, and the inside of the filter cloth 6 bypasses the first support roller 21. The second support roller 22 , the third support roller 23 , the fourth support roller 24 , and the fifth support roller 25 are close to the outside of the filter cloth 6 , so that the filter cloth 6 is in a tensioned state, showing an inverted ladder shape. The filter cloth 6 is made of polyester material, which can effectively remove suspended particles with a diameter of more than 30 μm in the water body through tests. Machine cover can prevent dust from dirtying th...

Embodiment 2

[0036] Different from Embodiment 1, this device does not have a water level sensor, but a sixth support roller 26 and a seventh support roller 27 are arranged between the second support roller 22 and the third support roller 23, and the sixth support roller 26 Located below the ultrasonic vibrating plate 17 , the seventh support roller 27 is located above the ultrasonic vibrating plate 17 . A first pressure sensor 33 and a second pressure sensor 34 are arranged below the sixth support roller 26 and the seventh support roller 27 respectively; the first pressure sensor 33 and the second pressure sensor 34 are respectively electrically connected to the controller. For the device where the sixth and seventh support rollers are arranged between the second and third support rollers, pressure sensors can be further installed under the sixth and seventh support rollers to detect the water level and make the detection more accurate.

Embodiment 3

[0038] Such as figure 1 and image 3 As shown, a crawler-type microfiltration machine includes a frame 2 arranged in a water tank 1, a machine cover 3 is provided at the upper end of the frame 2, a first support roller 21 and a second support roller 22 are provided at the bottom, and a second support roller 22 is provided at the top. Three supporting rollers 23, the middle part is provided with the fourth supporting roller 24, the fifth supporting roller 25, the inner side of the filter cloth 6 bypasses the first supporting roller 21, the second supporting roller 22, the third supporting roller 23, the fourth supporting roller 24, The fifth support roller 25 is close to the outer side of the filter cloth 6, so that the filter cloth 6 is in a tight state, showing an inverted ladder shape; the third support roller 23 is connected with a motor, and the motor drives the third support roller 23 to rotate, so as to realize the circulation of the filter cloth 6 Transmission; the fra...

Abstract

The invention relates to the field of water treatment in factory recirculating aquaculture system, in particular to a tracked microstrainer capable of filtering out suspended particles in water. The tracked microstrainer comprises a frame arranged in a water tank, and is characterized in that a hood is arranged at the upper end of the frame, a first supporting roller and a second supporting roller are arranged at the bottom of the frame, a third supporting roller is arranged at the bottom of the frame, and a fourth supporting roller and a fifth supporting roller are arranged in the middle of the frame; the inner side of filter cloth bypasses the first supporting roller, the second supporting roller, the third supporting roller and the fourth supporting roller, and the fifth supporting roller clings to the outer side of the filter cloth, so that the filter cloth is in a tightened state and in the shape of an inverted step; the third supporting roller is connected with a motor, and the motor drives the third supporting roller to rotate, so that circulating transmission of the filter cloth is achieved. The tracked microstrainer has the advantages that through one-side filtration, a built-in backwashing device, a plurality of sewage sumps and a plurality of drain outlets, the suspended particles in a water body can be removed effectively while secondary pollution is avoided effectively, and the tracked microstrainer is excellent in effect, low in purchasing, use and maintenance cost and the like.

Description

technical field [0001] The invention relates to the field of water treatment of a factory circulating aquaculture system, in particular to a crawler-type microfilter for filtering and removing suspended particles in water. Background technique [0002] The recirculating aquaculture system is a new type of aquaculture model, which uses a series of water treatment units to treat the wastewater generated in the aquaculture pond and then recycle it. This system is by far one of the most advanced and technologically advanced aquaculture models in the world. , is also the future development trend of the aquaculture industry. [0003] The recirculating aquaculture system is usually a high-density culture, and a large amount of residual bait feces, ammonia nitrogen (TAN), nitrite nitrogen (NO2--N) and other harmful pollutants will be produced in the water body, which is not conducive to the growth of fish, and may cause severe fish disease. In order to remove the above-mentioned h...
