Description

Technical field:

[0001] The utility model relates to a filter, in particular to a high-efficiency plate-frame filter, belonging to the technical field of filters. Background technology:

[0002] The plate and frame filter is a common solid-liquid separation equipment, which is widely used in the chemical, pharmaceutical, food, beverage and other industries. It filters the liquid through the combination of plate frame and filter cloth to remove solid particles and impurities, thereby achieving the purpose of solid-liquid separation. In the process of producing phycocyanin, a plate and frame filter is needed. By inputting the spirulina powder solution into the plate and frame filter, the solution can be filtered and deslag, and then after the concentration and drying process, phycocyanin powder can be obtained.

[0003] When the current plate and frame filter filters the spirulina powder solution, the filtrate residue will adhere to the filter screen due to the adhesion of the spirulina powder, thereby affecting the filtration efficiency of the plate and frame filter. Therefore, a high-efficiency plate and frame filter is proposed. Utility model content:

[0004] The purpose of the utility model is to provide a high-efficiency plate-frame filter to solve one of the problems raised in the above-mentioned background technology.

[0005] The utility model is implemented by the following technical scheme: a high-efficiency plate-frame filter, comprising a filter press assembly, the filter press assembly comprising six filter press frames, a filter screen, four push rods, a piston, four limit sleeves, two mounting frames, a push plate, a hydraulic cylinder, five springs and four guide rods;

[0006] The four guide rods are symmetrically fixedly connected to adjacent surfaces of the two mounting frames, one ends of the four push rods are symmetrically rotationally connected to one side of the filter screen, the piston is fixedly connected to the other end of the push rod, one ends of the four limiting sleeves are symmetrically fixedly connected to one side of the inner wall of the filter press frame, the filter screen is slidably connected to the inner wall of the filter press frame, the outer wall of the filter press frame is symmetrically fixedly connected to two mounting plates, the mounting plates are slidably connected to the outer walls of the guide rods, the push plates are fixedly connected to the piston shafts of the hydraulic cylinders, the five springs are all slidably connected to the outer walls of the guide rods, and the lengths of the two lower push rods are smaller than the lengths of the two upper push rods.

[0007] As a further preferred embodiment of the technical solution: one side of the outer wall of one filter press frame is slidably connected to the inner wall of another filter press frame, and both ends of the spring bear against adjacent surfaces of two corresponding mounting plates.

[0008] As a further preferred embodiment of the technical solution: a feed pipe is installed on the upper surface of the filter press frame, a drain pipe is installed on the lower surface of the filter press frame, and the feed pipe is located outside the filter screen.

[0009] As a further preferred embodiment of the technical solution: four air inlet pipes are symmetrically mounted on the upper surface and the lower surface of the filter press frame, and the air inlet pipes are connected to the limiting sleeve.

[0010] As a further preferred embodiment of the present technical solution: the piston is slidably connected to the inner wall of the limiting sleeve, and the filter is attached to one end of the limiting sleeve.

[0011] As a further preferred embodiment of the present technical solution: the hydraulic cylinder is installed on one side of a mounting frame.

[0012] As a further preferred embodiment of the technical solution: a support assembly is installed on the lower surface of the mounting frame, and the support assembly includes a support frame and a connecting rod;

[0013] The two mounting frames are symmetrically fixedly connected to the upper surface of the supporting frame, and the two adjacent filter press frames are connected by a connecting rod.

[0014] As a further preferred embodiment of the technical solution: a controller is installed on one side of the mounting frame, a storage box is installed on the upper surface of the support frame, and the storage box is located below the filter press frame.

[0015] Advantages of the utility model: under the push of the hydraulic cylinder, the spirulina powder solution in the filter press frame is filtered, and impurities remain on the filter screen in the filter press frame. When the hydraulic cylinder is reset, the filtration is completed, and the solution after filtering out the filter residue is discharged through the drain pipe. Then the spring pushes the filter press frames to separate from each other. At this time, air is inflated into the limiting sleeve through the air inlet pipe, the gas pushes the piston, the piston pushes the push rod, and the push rod pushes the filter screen, thereby moving the filter screen out of the filter press frame. Since the length of the push rod below is less than the length of the push rod above, the filter screen is tilted, and the upper part of the filter screen flips downward, thereby causing the filter residue on the surface of the filter screen to fall off, thereby ensuring the filtering efficiency of the filter screen.
