Description

Technical Field

[0001] The invention belongs to the technical field of flushing equipment, and particularly relates to a filter cloth flushing system and a flushing method for a filter press. Background Art

[0002] A filter press is a mechanical device that uses a special filtering medium to apply a certain pressure to an object so that liquid can be dialyzed out. It is a commonly used solid-liquid separation device. During the operation of the filter press, the filter cloth plays a crucial role. It can effectively intercept and separate solid particles from liquid, ensuring the filtering effect of the filter press. During the long-term operation of the filter press, a large amount of impurities will gradually accumulate on the surface of the filter cloth. These impurities will not only reduce the filtering performance of the filter cloth, resulting in a decrease in filtering efficiency, but also increase the resistance of the filter cloth, affecting the normal operation of the filter press, and may even damage the filter cloth and shorten its service life.

[0003] Most traditional filter cloth flushing methods use manual flushing or simple flushing equipment. The manual flushing method has a high labor intensity, low efficiency, and it is difficult to guarantee the flushing effect. It is impossible to comprehensively and deeply clean the filter cloth. It is difficult to effectively remove impurities and stubborn stains in the fiber gaps of the filter cloth, and problems such as uneven flushing and impurity residue are likely to occur. In addition, traditional flushing methods also have deficiencies in drying the filter cloth. Usually, the natural drying method is used, which has a long drying time and is easily affected by environmental factors, resulting in incomplete drying of the filter cloth and affecting the subsequent use of the filter press. Summary of the Invention

[0004] The purpose of the present invention is to provide a filter cloth flushing system and a flushing method for a filter press. The water in the water tank is transported to the nozzle through a transfer pump to initially flush the surface of the filter cloth and remove most of the easily removable impurities. Then, a scraper is used to scrape and block the larger sundries on the filter cloth. Subsequently, a motor is installed to drive the connecting rod, transfer wheel, and conveyor belt to drive, so that the moving plate transports the residual sundries on the filter cloth surface to the bottom of the fixed box, and the sundries on the filter cloth can be removed. The fixed motor drives the cleaning rod and the extrusion tube to rotate. The cleaning rod transversely cleans the filter cloth, and the extrusion block on the extrusion tube squeezes the filter cloth to reduce the water content. Finally, the hot air generated by the dryer body passes through the extrusion tube to dry the filter cloth, improving the drying efficiency of the filter cloth and ensuring that the filter cloth can quickly recover its use performance.

Subsequently, a motor is installed to drive the connecting rod, transfer wheel, and conveyor belt to drive the moving plate to transfer the residual debris on the surface of the filter cloth to the bottom of the fixed box, so as to remove debris from the filter cloth.

[0019] (2) In the present invention, a fixed motor drives the cleaning rod and the extrusion tube to rotate. The cleaning rod performs lateral cleaning on the filter cloth, and the extrusion block on the extrusion tube squeezes the filter cloth to reduce moisture. Finally, the hot air generated by the dryer body passes through the extrusion tube to dry the filter cloth, improving the drying efficiency of the filter cloth and ensuring that the filter cloth can quickly recover its service performance.

The nozzle (206) sprays water to rinse the surface of the filter cloth. S2. Remove debris: The squeegee (502) scrapes and blocks the debris on the filter cloth. By turning on the mounting motor (503), the mounting motor (503) drives one of the connecting rods (504) to rotate. Through the transmission of the transmission wheel (505) and the transmission belt (506), the transmission belt (506) drives the moving plate (507) to move. The moving plate (507) transports the debris on the surface of the filter cloth to the bottom of the fixed box (201), removes the debris on the surface of the filter cloth, and longitudinally flushes and cleans the filter cloth. S3. Clean and dry the filter cloth: Turn on the fixed motor (402). The fixed motor (402) rotates to drive one of the cleaning rods (403) to rotate. Through the transmission of the fixed synchronous wheel (404) and the synchronous belt, the fixed rod (405) drives the transmission synchronous wheel (406) to rotate, so that the other cleaning rod (403) and the four extrusion tubes (408) rotate. The cleaning rod (403) squeezes the extrusion tube (408) of the filter cloth for transverse cleaning of the filter cloth. The extrusion tube (408) drives the extrusion block (409) to squeeze the filter cloth to reduce the moisture on the filter cloth. At the same time, turn on the dryer body (302). Through the transmission of the transmission pipe (303) and the connecting pipe (304), hot air dries the filter cloth through the extrusion tube (408).
