Description

Technical Field

[0001] The utility model relates to the technical field of filter press cleaning, in particular to a filter cloth cleaning device for a plate and frame filter press. Background Art

[0002] For the solid-liquid separation of products, a plate-and-frame filter press is generally required. The plate-and-frame filter press is an intermittent solid-liquid separation device. It is composed of filter plates and filter frames arranged to form a filter chamber. Under the pressure of the feed pump, the feed liquid is sent into each filter chamber, and the solid and liquid are separated by the filter medium. This equipment is widely used in chemical industry, dye, petroleum, ceramics, pharmaceuticals, sugar, starch, paint, metallurgy and sewage treatment.

[0003] When the existing plate-and-frame filter press is working, after filtering, the filter residue needs to be cleaned. There are a lot of filter residues attached to the filter cloth, and the filter residue often sticks to the filter cloth. At present, when cleaning the filter residue on the filter cloth, it is generally cleaned by spraying water. The water jet is sprayed from the high-pressure nozzle and acts on the filter cloth, thereby cleaning the filter residue on the filter cloth. Although this method can realize the cleaning of the filter plate, it also has the problem of wasting water resources. In addition, the filter cloth cleaning device is generally installed on the plate-and-frame filter press body at present, and the modification cost is high, which may affect the original normal operation of the plate-and-frame filter press body. And because the filter cloth cleaning frequency is low, the filter cloth cleaning device installed on the plate-and-frame filter press body has a low utilization rate and is not cost-effective. Utility Model Content

[0004] The utility model aims to provide a filter cloth cleaning device for a plate and frame filter press, which can make the residue on the filter cloth fall off by vibration, is more environmentally friendly, saves water resources, has lower costs, can be instantly attached to and separated from the plate and frame filter press body, and can realize the cleaning work of one filter cloth cleaning device cooperating with multiple plate and frame filter presses.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a filter cloth cleaning device for a plate and frame filter press, comprising two vertically arranged support columns, two universal wheels are respectively provided at the bottom of the support columns, the tops of the support columns are fixedly connected by a horizontally arranged multi-section telescopic hydraulic rod, a vibration motor is detachably and horizontally provided on the support column, the output end of the vibration motor is arranged inwardly, and a controller for controlling the vibration motor and the multi-section telescopic hydraulic rod is provided on the support column.

[0006] Preferably, a fixing ring cooperating with the supporting column is provided at the tail end of the vibration motor, and a plurality of fixing bolts for detachably fixing the fixing ring are also provided on the fixing ring.

[0007] Preferably, a silicone plate is provided on the output end of the vibration motor.

[0008] Preferably, the four universal wheels are arranged in a rectangular shape as a whole.

[0009] The beneficial effects of the utility model are:

[0010] Compared with the traditional method of directly cleaning with high-pressure water jets, this filter cloth cleaning device directly causes the residue on the filter cloth to fall off through vibration, which is more environmentally friendly, saves water resources, and has lower costs. Compared with the method of directly installing on the plate and frame filter press body, the modification cost is lower and will not affect the original normal operation of the plate and frame filter press body. One filter cloth cleaning device can be used to clean multiple plate and frame filter presses, thereby improving the utilization rate of the filter cloth cleaning device and having a high cost-effectiveness ratio. In addition, the height of the vibration motor and the distance between the two vibration motors can be adjusted, which can adapt to the filter cloth cleaning work of various types of plate and frame filter presses.
