Description

Technical Field

[0001] This utility model belongs to the field of filter cloth cleaning, and in particular relates to a filter cloth cleaning and drying device for a pressure filter machine. Background Technology

[0002] A pressure filter is a device used for solid-liquid separation, promoting the separation of liquids and solids by applying external pressure. It is widely used in industries such as chemical, food, and environmental protection, offering advantages such as high-efficiency filtration and automated operation. It mainly consists of a filter chamber, filter cloth, pressurizing device, slag discharge device, and liquid discharge device.

[0003] Over time, as pressure filters are used, the filter cloth comes into continuous contact with the filtered material, gradually accumulating impurities and forming a dirt layer, which increases the resistance of the filter cloth. This often leads to a slower filtration speed, longer filtration cycles, and may even cause a significant decrease in filtration efficiency. Utility Model Content

The multiple rinsing components 2 are evenly distributed in a ring. The flushing assembly 2 is fixedly installed on the inner wall of the barrel 11. It includes a water inlet pipe 21 and multiple nozzles 22. The lower end of the water inlet pipe 21 passes through the barrel 11 and extends to the outside of the barrel 11 to connect with the external water supply system. The multiple nozzles 22 are fixedly arranged radially at equal intervals on the side of the water inlet pipe 21. The rotating assembly 3 includes a motor 31 and a rotating rod 32. The motor 31 is fixedly installed in the middle of the bottom surface of the barrel 11. The main shaft of the motor 31 passes through the bottom of the barrel 11 and extends into the barrel 11 to be fixedly connected with the rotating rod 32. The multiple filter cloths 4 are fixedly fitted on the outside of the rotating rod 32.

[0025] In one embodiment of this utility model, multiple filter cloths 4 are fitted onto the outside of the rotating rod 32. Washing liquid is added into the tank 11 in conjunction with the washing component 2. The motor 31 is started to drive the rotating rod 32 to rotate and wash the filter cloths 4. By controlling the rotation speed of the motor 31, the filter cloths 4 are washed more effectively. After washing, the wastewater in the tank 11 is discharged. The high-speed rotation of the rotating rod 32, under the action of centrifugal force, spins the water off the filter cloths 4. The cleaning effect of the filter cloths 4 can be improved by repeating the washing process multiple times.

[0026] like Figure 1 and Figure 2 As shown, in another embodiment of the present invention, a sealing ring 13 is fixedly installed on the side of the bucket lid 12. The sealing ring 13 is configured as an annular structure, the outer diameter of the sealing ring 13 is adapted to the inner diameter of the bucket body 11, and the sealing ring 13 is made of an elastic material.

[0027] In one embodiment of this utility model, the opening on the tub body 11 is sealed by the tub lid 12 and the sealing ring 13, which can prevent the rotating rod 32 from rotating the filter cloth 4 and splashing liquid out during the washing process, ensuring the cleanliness of the site and preventing debris from entering the tub body 11 and affecting the washing work. At the same time, the tub lid 12 can also isolate the rotating equipment to prevent workers from being injured due to misoperation.

[0028] like Figure 2 and Figure 4As shown, in another embodiment of the present invention, the rotating rod 32 includes a mounting shaft 321, a clamping block 322, and a fixing nut 323. A limiting ring 3211 is fixedly provided on the outer side of the mounting shaft 321. The clamping block 322 is movably fitted on the outer side of the mounting shaft 321 and located above the limiting ring 3211. An external thread 3213 is fixedly provided at the top end of the mounting shaft 321. The fixing nut 323 is screwed onto the outer side of the external thread 3213.

[0029] Specifically, each of the filter cloths 4 has a central hole 41 fixedly opened at its center position. Multiple filter cloths 4 are fitted onto the outside of the mounting shaft 321 through the central hole 41 and are clamped and fixed by the limiting ring 3211, clamping block 322 and fixing nut 323. Multiple clamping blocks 322 are located between the filter cloths 4.

[0030] In one embodiment of this utility model, multiple filter cloths 4 are clamped and fixed by the central hole 41, the fixing nut 323 and the clamping block 322, which facilitates the installation of the filter cloths 4. The clamping block 322 separates the filter cloths 4 by a certain distance, thereby preventing the filter cloths 4 from getting tangled together during washing and improving the washing effect.

[0031] like Figure 2 and Figure 4 As shown, in another embodiment of the present utility model, a plurality of limiting grooves 3212 are fixedly opened on the outer side of the mounting shaft 321, and a plurality of limiting blocks 3221 are fixedly arranged on the inner side of the clamping block 322 at the position corresponding to the limiting grooves 3212, and the limiting blocks 3221 are movably clamped in the limiting grooves 3212.

[0032] In one embodiment of this utility model, the clamping block 322 can be limited by the limiting block 3221 and the limiting groove 3212, so that the clamping block 322 and multiple filter cloths 4 can be installed and fixed by the fixing nut 323, effectively preventing the clamping block 322 and the filter cloth 4 from rotating relative to each other, thereby causing pulling damage to the filter cloth 4.

[0033] like Figure 2 and Figure 3 As shown, in another embodiment of the present invention, the gaps between the plurality of nozzles 22 and the plurality of filter cloths 4 are aligned one by one.

[0034] In one embodiment of this utility model, a rotating rod 32 drives multiple filter cloths 4 to rotate. Under the action of centrifugal force, the filter cloths 4 are horizontally unfolded. At this time, a high-speed water jet is sprayed through the nozzle 22, which can rinse the surface of the filter cloths 4 and further improve the cleaning effect.
