Description

Technical Field

[0001] The utility model belongs to the technical field of filter presses, and particularly relates to a filter press for sludge drying and treatment. Background Art

[0002] Filter press is a commonly used solid-liquid separation equipment. It uses a special filter medium to apply a certain pressure to the object to make the liquid seep out. It is a mechanical equipment used for separation and dehydration of difficult-to-separate materials with large filtration volume, fine particle size and high viscosity. It is widely used in solid-liquid separation of various materials in petroleum, chemical, pharmaceutical, starch, sugar making, food, beverage, mining, soap making, environmental protection and water treatment departments. The main purpose of the filter press is to use it as a filter press equipment to treat liquid and other sewage, and can filter materials through pressure.

[0003] A Chinese patent with publication number CN215876375U discloses a high-efficiency filter plate cleaning filter press, including a filter press body, a cleaning device is provided on the top of the filter press body, including a mounting plate, an adjusting motor, a pulley, a rotating shaft, a winding wheel, a steel cable, a guide plate, a hollow shaft and an injection disc, the mounting plate is fixedly connected to the top of the filter press body, there are two mounting plates, two rotating shafts are rotatably connected between the two mounting plates, a plurality of winding wheels are installed on the rotating shaft, a steel cable is provided on the winding wheel, a guide plate is connected to the steel cable, an external water pipe of the guide plate is connected to a water pump, a hollow shaft is rotatably connected to the bottom of the guide plate, an injection disc is installed on the hollow shaft, and six arc-shaped pipes are provided in the injection disc.

[0004] The filter press in the above-mentioned prior art still has certain shortcomings during use. For example, the guide plate is connected by a steel cable on the winding wheel. Although it can be freely extended and retracted under the drive of the adjusting motor, the guide plate will be subjected to the reaction force from the filter cloth on the plate frame when releasing the cleaning water, which will cause the guide plate to shake unstably, thereby affecting the cleaning effect of the injection disc. Secondly, the plate and frame filter press is generally installed on the filter press platform. When the flap door on the filter press platform is opened, the sludge can be discharged conveniently. However, the cleaning water is directly discharged on the spot during cleaning, which easily causes the accumulated cleaning water to penetrate into the dehydrated sludge along the gap of the flip door.
