Description

Technical Field

[0001] The utility model relates to a belt filter, belonging to the technical field of filter equipment. Background Art

[0002] The endless belt of the belt vacuum filter is driven by a motor to run continuously. A water seal is formed between the belt and the vacuum slide through the contact of the endless friction belt to prevent the vacuum environment from being damaged. The main filtering medium of the belt vacuum filter is the filter cloth, and the slurry is evenly spread on the filter cloth by a distributor.

[0003] According to the announcement number CN208878024U, a filter belt filter with a washing function is disclosed, including a base, a filter belt and a brush. Support frames are installed on both ends of the left and right ends of the base, and a water supply tank is fixed on the upper left of the base. The filter belt is connected to the right end of the first rotor, and a filter chamber is provided on the upper left of the filter belt. The brush is installed at the lower end of the third rotor, and the lower end of the brush is connected to a rotating shaft. When the pressure pump of the filter belt filter with washing function is working, the water in the water tank can be transported to the inside of the filter chamber through the water pipe to wash and filter the slurry on the filter belt. Since the speed of the first motor is slow, the filter belt moves slowly to the right, so the washing and filtering operation can be completed multiple times in the filter chamber, so that the slurry is filtered more purely and the quality of the finished product is improved. The third rotor is located inside the cleaning box, and the second motor can drive the brush to rotate to brush the filter belt at the bottom of the third rotor to keep the filter belt clean. The above device cannot adjust the height of the brush. When the device is used for a long time, it is easy for the filter belt to be loose and the brush to be worn and unable to contact the filter belt, thereby affecting the normal use of the device.
