Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to sludge filter pressing equipment. Background Art

[0002] Sludge treatment filter press equipment is a mechanical device used in sewage treatment plants or related industrial processes to dehydrate sludge. It applies pressure to allow the water in the sludge to be discharged through the filter cloth, thereby reducing the water content of the sludge and facilitating transportation and disposal. Filter press equipment usually includes filter press body, filter cloth, hydraulic system and other components. After the sludge is treated by filter pressure, the volume of the sludge can be greatly reduced and the burden on the environment can be reduced. A plate and frame filter press is a device that applies a pressure higher than atmospheric pressure during the filtration process to form a filtration driving force of normal pressure or slightly higher than normal pressure at the filtrate outlet of the filter medium. The plate and frame filter press has the characteristics of large filtration area, large flow rate and wide application range. The use process of the plate filter press generally includes the following steps: the sludge or filter material is evenly spread on the filter cloth, and then the filter press is started for pressurized filtration. As the pressure increases, the moisture in the sludge is retained by the filter cloth and gradually forms a filter cake. When the filter cake is formed to a certain extent, the pressure is stopped and the plate separation device is used to unload the material. After unloading, the filter cloth is cleaned for next use. The existing unloading method is usually that the filter cake falls off the filter cloth by gravity, but the filter cake is prone to incomplete falling off during use, and manual assistance is still required, which reduces the unloading efficiency and affects the automation of the device. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a sludge filter press equipment to solve the problem that the existing unloading method is usually that the filter cake relies on gravity to fall off the filter cloth, but during use, the filter cake is prone to incomplete falling off and still requires manual assistance, which reduces the unloading efficiency and affects the automation of the device.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows: a sludge filter press equipment, including a device frame and a second driving motor, a sliding bracket is installed on the device frame, and a driving motor is installed on both sides of the sliding bracket, the output end of the driving motor is installed with a moving roller through a reduction motor, a moving gear is installed in the middle part of the moving roller, and a moving rack is meshed and connected below the moving gear, the second driving motor is installed on the top of the device frame, and a screw is installed at the output end of the second driving motor, a slider is installed on the screw, and a mounting bracket is welded below the slider, a servo motor is installed at the bottom of the mounting bracket, and a rotating seat is installed at the output end of the servo motor, a high-pressure spray pipe is installed on the inner side of the rotating seat, and a clean water pipe is installed at one end of the high-pressure spray pipe close to the servo motor, a telescopic motor is plugged and installed on the rotating seat, and a connecting rod is connected to the output end of the telescopic motor, a push rod is installed at the front end of the connecting rod through a flip shaft, and the end of the push rod away from the connecting rod is connected to a brush plate seat through a flip shaft, and the outer side of the brush plate seat is wrapped with a brush plate.

[0005] The beneficial effects of the utility model are as follows: the telescopic motor pushes the push rod to flip along the flip axis through the connecting rod, and the push rod pushes the brush plate seat to contact the brush plate and the filter press plate. After the contact is completed, the driving motor 2 drives the brush plate to slide along the screw rod and the smooth rod through the screw rod and the slider, and the filter cake that has not completely fallen off the filter press plate is scraped off. This method can effectively and quickly clean the filter press plate, and can also effectively ensure the comprehensive detachment of the filter cake, thereby ensuring the efficiency and effect of unloading.

At this time, the filter press hydraulic cylinder pushes the filter press plate to filter the sludge, and the filtered water is discharged into the interior of the drain through the liquid outlet pipe. After the filtration is completed, the sludge is stopped from being added. At this time, the plate separation device slides along the installation cross plate to pull the filter press plate apart, and the filter cake falls to complete the sludge filtration.

[0009] To facilitate the rotation of the mobile gear:

[0010] As a further improvement of the above technical solution: the moving roller and the moving gear are coaxially arranged.

[0017] The beneficial effect of this improvement is that the polished rod can guide the sliding of the slider, and the parallel arrangement can make the sliding of the slider more reliable and stable.
