[0002] The filter is a kind of filtering equipment needed in concrete mixing plants, mortar preparation systems, spray dust reduction systems and other occasions in the construction industry. This type of filter is mainly used to remove suspended matter, particulate matter, silt and other impurities in the water to ensure the normal operation of construction machinery and extend its service life.

[0003] During the use of the filter, impurities in the water will gradually settle on the filter screen inside the filter, which will increase the water inlet pressure and deteriorate the filtering effect. After a period of use, the staff will need to disassemble the filter housing and / or remove the filter screen for manual flushing, which is troublesome and time-consuming. In addition, long-term downtime will greatly affect the continued operation of the construction machinery and affect the processing efficiency. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-Figure 5 A self-cleaning filter is shown, comprising a filter cartridge 1, a water supply pipe being connected to the top end of the filter cartridge 1, and a counterclockwise rotatable mounting bar 12 being provided inside the filter cartridge 1, and two baffles 13 and two filter meshes 14 being installed in a circular array on the outer wall of the mounting bar 12, the baffles 13 and the filter meshes 14 being staggered, adjacent baffles 13 and filter meshes 14 being arranged at 90°, and the ends of the baffles 13 and the filter meshes 14 both being in contact with the inner wall of the filter cartridge 1.

[0026] Among them, in order to make the mounting bar 12 rotatable, a motor 2 is installed at the front end of the outer wall of the filter cartridge 1. The motor 2 is preferably a stepping motor, and a connecting shaft is installed between the output end of the motor 2 and the end of the mounting bar 12. The other end of the mounting bar 12 is connected to the rear end of the inner wall of the filter cartridge 1 through a bearing seat. The output end of the motor 2 is used to drive the connecting shaft to rotate, thereby realizing the reverse rotation of the mounting bar 12.

[0027] The water supply pipe includes a water inlet branch pipe 5 and a water inlet main pipe 6 . There are three water inlet branch pipes 5 , and the water inlet ends of the water inlet branch pipes 5 are connected to the water receiving and filtering area. The top ends of the three water inlet branch pipes 5 are connected to the water inlet main pipe 6 .

[0028] In addition, see Figure 3 and Figure 4 As shown, starting from the upper end of the interior of the filter cartridge 1 and in a counterclockwise direction, two baffles 13 and two filter meshes 14 divide the interior of the filter cartridge 1 into a water receiving filtration area, a flushing area, a sewage discharge area and a drainage area. The bottom end of the sewage discharge area is connected to a sewage pipe 4, and the outer wall of the drainage area is connected to an outlet pipe 10 for discharging filtered water. The outlet pipe 10 is inclined, and the inclination angle of the outlet pipe 10 is equal to the inclination angle of the baffle 13 in the initial state. In the initial state, the flushing area is provided with a flushing component, which includes a flushing part and a circulating water supply part. One of the filter meshes 14 separates the water receiving filtration area and the drainage area, so that the water sent into the water receiving filtration area can leak from the filter mesh 14 into the drainage area after filtration, and then be discharged from the outlet pipe 10 to the subsequent stage.

[0029] Through the above technical solution:

[0030] During specific use, the water to be filtered can be connected to the water inlet pipe 6 through a water pipe. The water inlet pipe 6 sends the water to be filtered to three water inlet pipes 6, and then enters the water receiving and filtering area from three positions, and is filtered by the filter mesh 14 in the water receiving and filtering area. The water that passes through enters the drainage area and is then discharged through the outlet pipe 10.

[0031] Among them, when the filter mesh 14 in the water receiving and filtering area needs to be cleaned, the controller (not shown) can be used to start the motor 2, and the output end of the motor 2 can be used to drive the mounting bar 12 to rotate 180° counterclockwise, so that the filter mesh 14 to be cleaned can be rotated to the lower left to separate the flushing area and the sewage discharge area. The filter mesh 14 originally at the lower left is changed to the original position of the filter mesh 14 to be cleaned, so as to serve as a separator between the water receiving and filtering area and the drainage area. At this time, the filter can continue to be used. For the filter mesh 14 to be cleaned that is rotated to the bottom, it can be cleaned by the flushing component. The cleaning and filtering do not interfere with each other, and there is no need to stop the machine for cleaning for a long time, which greatly improves the processing efficiency.

[0032] In addition, see Figure 1 and Figure 2 As shown, the flushing part includes a flushing tray 3 and an external water pipe 9. The flushing tray 3 penetrates the outer wall of the flushing area. The external water pipe 9 is connected to the water inlet at the outer end of the flushing tray 3, and a plurality of water spray ports 15 are opened at the inner end of the flushing tray 3.

[0033] The circulating water supply part includes a water pump 7 , a water delivery pipe 8 and a water extraction pipe 11 . The water extraction pipe 11 is connected between the water outlet pipe 10 and the water inlet end of the water pump 7 , and the water delivery pipe 8 is connected between the external water pipe 9 and the water outlet end of the water pump 7 .

[0034] Through the above, when the cleaning rotates to the lower filter mesh 14 to be cleaned, the external water pipe 9 can be used to connect the water discharged from the outlet pipe 10. After the water enters the flushing plate 3, it can be sprayed from multiple water nozzles 15 on the back of the filter mesh 14 to be cleaned, so as to quickly clean the impurities. The cleaned impurities can be discharged from the sewage pipe 4 in the sewage discharge area.

[0035] The water pump 7 can also be started to directly draw water from the water outlet pipe 10 using the water pumping pipe 11, and the water is sent to the external water pipe 9 through the water delivery pipe 8, and then the same flushing operation as above is performed, which is more convenient and quick.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
