technical field

The invention belongs to the field of waste water treatment in food processing, in particular to a high-fat food processing waste water treatment device.

Background technique

Food processing requires a large amount of water. In high-fat food processing, more wastewater will be produced. This type of wastewater often contains more impurities such as suspended solids and particulate matter. Filtering treatment is required when purifying wastewater.

In the filter device of the existing wastewater treatment device, the waste water is usually filtered and removed through the filter screen. During the waste water filtration process, the impurities will accumulate on the surface of the filter screen.

Therefore, the existing wastewater treatment device has the problems of inconvenient cleaning of the filter structure, easy clogging, and easy damage. Therefore, we propose a high-fat food processing wastewater treatment device.

Contents of the invention

The purpose of the present invention is to provide a high-fat food processing wastewater treatment device, which can effectively solve the problems of inconvenient cleaning, easy clogging and easy damage of the filter structure in the existing wastewater treatment device proposed in the background art.

The water guide plate is arranged obliquely. The filter component is used to discharge impurities in the waste water in time, and the water pressure per unit area is low.

The miscellaneous filter assembly includes a roller movably arranged inside the support seat, a filter cloth sleeved on the side of the roller ring, a retaining ring fixedly arranged on the edge of the filter cloth, a scraper fixedly arranged on one side of the support seat, and a servo motor fixedly arranged on the side of one of the support seats. The edge of the filter cloth flows out and is used to enhance the tensile resistance of the filter cloth. The servo motor drives one of the rollers to rotate, and the water guide plate is located in the middle of the filter cloth and the inner side of the retaining ring; the waste water enters the filter cloth from a fixed point above one of the rollers, and the servo motor drives the filter cloth through the roller, and the filter cloth drives the waste water to move to the other roller. Under the whole cloth, during this process, the waste water seeps into the filter cloth to be filtered, and the pressure of the waste water per unit area of the filter cloth is small, which avoids the problem of damage to the filter cloth due to excessive force caused by excessive water pressure on the filter cloth, improves the service life of the filter cloth, and at the same time makes the impurity force small, and it is not easy to enter the inside of the filter cloth when being filtered, and the impurity enters the bottom of the filter cloth during the transmission, and can fall directly under the action of gravity. Adhesion, can be removed in time, and can be cleaned, avoiding the problem of impurities accumulating to block the filter holes, easy to ensure the filtration efficiency, and make the overall filtration capacity of the device stable.

The tensioning assembly includes two lifting platforms fixed above the water guide plate, tension rollers and squeeze rollers movable inside the two lifting platforms, absorbent cotton fixed on the side of the tension roller ring, and a drive motor fixed on one of the lifting platforms. The tension roller and absorbent cotton are raised and lowered by the lifting platform, so that the filter cloth and the retaining ring are in a proper tension state, and at the same time, it is convenient to adjust the inclination angle of the upper filter cloth and the upper part of the retaining ring, so that the flow rate of the wastewater on the filter cloth can be adjusted during the filter cloth water delivery process. At the same time, through the tension effect, there is a greater pressure between the absorbent cotton and the filter cloth, which increases the contact surface between the absorbent cotton and the filter cloth, which is convenient for increasing the absorption of wastewater by the absorbent cotton and reducing the residue of wastewater on the filter cloth. Squeeze out the waste water inside.

Preferably, the heights of the two rollers are different, so that the filter cloth is inclined, and the angle between the filter cloth and the horizontal direction is in the range of 5°-10°.
