Belt transmission-type microstrainer

Abstract

The invention relates to a belt transmission-type microstrainer, and belongs to the field of a water filter apparatus. The belt transmission-type microstrainer comprises a roller, wherein the roller comprises a roller skeleton and a filter screen wrapping the roller skeleton, two ends of the roller skeleton sleeve a middle shaft by virtue of a bearing, the middle shaft is hollow, a hollow part is divided into two parts, i.e. a part A and a part B, by virtue of a baffle plate, the part A is respectively connected with a water inlet and a spray head installed on the middle shaft, the part B is communicated with a sewage collection trough arranged on the middle shaft, the middle shaft is also provided with a high-pressure water gun, the high-pressure water gun is disposed outside the roller skeleton, the sewage collection trough is disposed in the roller skeleton, the sewage collection trough is matched with the position of the high-pressure water gun, water sprayed by the high-pressure water gun can fall into the sewage collection trough after washing the filter screen, and the middle shaft is installed on a supporting frame. When the filter screen is blocked, the high-pressure water gun can be automatically opened to wash the filter screen, and high efficiency in filtering can be realized.

Description

technical field [0001] The invention relates to a belt-driven microfilter, which belongs to the field of water filtering devices. Background technique [0002] The drum microfiltration machine used in the aquaculture industry functions to filter the solid impurities in the water through the rotation of the filter drum to achieve solid-liquid separation, thereby purifying the water quality. There are two types of drum microfilters, one uses a high-pressure water pump to pump water into the drum microfilter, and uses the impact force of water to impact the blades in the drum to drive the drum to rotate. However, this method needs to be driven by water. This kind of soft transmission will cause serious energy loss, and when the power is running at high power or there are too many impurities in the drum, it will be impossible to push the drum or accelerate the drum to the specified speed. The other type uses a transmission chain to drive the drum to rotate. However, once the mi...

AI Technical Summary

Problems solved by technology

There are two types of drum microfilters in existence. One type uses a high-pressure water pump to pump water into the drum microfilter. The impulsive force of the water impacts the blades in the drum to drive the drum to rotate. However, this method needs to be driven by water. This kind of soft transmission will make the energy loss very serious, and when the high power is running or there are too many impurities in the drum, it will be impossible to push the drum or accelerate the drum to the specified speed

The other type uses a drive chain to drive the drum to rotate, but once the microfilter is powered off, the drum continues to rotate due to inertia, which can easily cause safety problems such as twisting of the rolling shaft, breakage of the drive chain, breakage of the sprocket teeth, and damage to the motor.
