Description

Technical Field

[0001] The utility model relates to the technical field of filter press equipment, in particular to a full-automatic filter press. Background Art

[0002] The filter press uses a special filter medium to apply a certain pressure to the object, causing the liquid to seep out. It is a commonly used solid-liquid separation equipment, often used for solid-liquid separation of sewage slurry.

[0003] The mud material contains tiny particles, which can easily clog the air pores of the filter cloth. Moreover, when encountering a filter cake with high viscosity, it is easy to cause unclean unloading, or even stick to the filter cloth, which requires manual scraping, greatly reducing work efficiency and work quality. After the mud cake is separated, some of it will still stick to the surface of the filter cloth, affecting the subsequent filter pressing effect and having poor practicality. Utility Model Content

[0007] A water spray pipe is fixedly connected to one side of the water tank, and the water spray pipe is located on the inner side of the transmission filter belt. A pump liquid component for injecting water into the water spray pipe is fixedly installed on the side wall of the water tank. A diffusion structure for dispersing mud is provided on the upper side of the water tank.

[0008] When using the above-mentioned fully automatic filter press, the mud input pipe is placed on one side of the transmission filter belt, and one of the rollers is driven to rotate by the motor. When the mud falls on the surface of the transmission filter belt, it moves with it and contacts the diffusion structure to be evenly dispersed, so that the mud is evenly spread on the surface of the transmission filter belt. According to the required degree of filtration, the roller frame is driven downward in the gantry through the adjustment component, so that the squeezing roller moves downward and contacts the surface of the transmission filter belt, and squeezes the mud on the surface of the transmission filter belt through cooperation with the fixed roller, squeezes out the water therein, and falls into the water tank. As the transmission filter belt moves, the mud cake with squeezed water falls from the other roller to the outside of the water tank for centralized collection. At the same time, the pump liquid component is controlled to work, and the clean water inside the water tank is pumped into the water spray pipe and sprayed onto the surface of the transmission filter belt to wash away the mud adhering to its surface, and the cyclic filtration is used.

[0009] Preferably, both side walls of the water tank are provided with sliding grooves that are slidably connected to the roller frame.

[0010] Preferably, the adjustment assembly includes a threaded hole opened in the middle of the portal frame, a threaded rod is threadedly connected to the threaded hole, and the lower end of the threaded rod is rotatably connected to the roller frame.

[0011] Preferably, a top roller is rotatably connected to the lower side of the water tank, and the top roller is located on the inner side of the transmission filter belt and abuts against it.

[0012] Preferably, a scraper is fixedly connected to one side of the water tank close to the groove, and the scraper abuts against the surface of the transmission filter belt.

[0013] Preferably, the water spray pipe is provided with a plurality of high-pressure nozzles, which are directed toward the inner surface of the transmission filter belt.

[0014] Preferably, the pump liquid assembly includes a water pump fixedly mounted on the side wall of the water tank, the liquid inlet of the water pump is connected to the inside of the water tank through an inlet pipe, and the liquid outlet of the water pump is connected to the water spray pipe through an outlet pipe.

[0016] The beneficial effects are:

[0017] After the mud falls on the surface of the transmission filter belt, it moves with it and contacts with the diffusion structure to be evenly dispersed. The mud on the surface of the transmission filter belt is squeezed out of the water by cooperation with the fixed roller, and the water is squeezed out and falls into the water tank. As the transmission filter belt moves, the mud cake with the water squeezed out falls from the other roller to the outside of the water tank for centralized collection. At the same time, the pump liquid component is controlled to work, and the clean water inside the water tank is pumped into the water pipe and sprayed onto the surface of the transmission filter belt to wash away the mud adhering to its surface. The filter is then used in a cycle. The whole operation process is quick and convenient. At the same time, the shedding of the mud cake and the cleaning of the transmission filter belt are fully automatic, which improves the filter pressing effect and practicality.

[0027] A water spray pipe 14 is fixedly connected to one side of the water tank 1, and the water spray pipe 14 is located on the inner side of the transmission filter belt 5. A pump liquid component 4 for injecting water into the water spray pipe 14 is fixedly installed on the side wall of the water tank 1. A diffusion structure for dispersing mud is provided on the upper side of the water tank 1.

[0028] Specifically, sliding grooves 11 slidably connected to the roller frame 8 are provided on both side walls of the water tank 1. The roller frame 8 can be limited by the sliding grooves 11, and the roller frame 8 can be made more stable when moving up and down.
