Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to an automatic flushing mechanism for a filter press. Background Art

[0002] Sewage treatment filter press is a filtering and separation equipment used in sludge, chemical industry, environmental protection and other fields. Sewage treatment filter press is divided into chamber type sewage treatment filter press, plate and frame filter press, belt filter press, vertical filter press, diaphragm filter press, etc.

[0003] like Figure 4 As shown in the figure, it is an automatic flushing mechanism of the previous generation installed on the flushing station of the belt filter press. Its main function is to flush the conveyor belt after the slag is discharged from the filter press to remove the solid impurities adhering to the surface of the belt body. However, this automatic flushing mechanism has the following shortcomings in actual use: although the flushing mechanism can flush down most of the solid impurities attached to the belt body, some stubborn impurities are still easy to remain on the belt body. When the uncleanly flushed belt body circulates into the filter press, it is easy to cause problems such as the belt body being squeezed and damaged and the filter press working abnormally.

[0004] In view of this, it is particularly important to design and manufacture an automatic flushing mechanism that can effectively improve the belt flushing effect and reduce the adhesion of solid impurities in sewage treatment filter presses. Utility Model Content

[0005] The utility model aims to solve the problem that the automatic flushing mechanism for the previous generation of filter press is difficult to effectively flush the belt body, and stubborn impurities are still easy to adhere to the surface of the belt body, affecting the normal operation of the filter press, and proposes an automatic flushing mechanism for the filter press.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An automatic flushing mechanism for a filter press comprises a frame, a spray bar installed on the left side of the upper end of the frame and distributed in an inclined manner, a plurality of atomizing nozzles equidistantly connected to the lower end of the spray bar, and an electromagnetic control valve installed at the upper end of the spray bar, a mounting frame is arranged on the inner side of the right end of the frame, the front end and the rear end of the mounting frame are fixedly connected to guide columns penetrating the frame, the front end and the rear end of the frame are installed with guide sleeves corresponding to the guide columns, the lower end of the mounting frame is detachably mounted with a brush plate through a quick-mounting portion, and a driving portion for driving the mounting frame to swing back and forth laterally is arranged between the frame and the upper end of the mounting frame.

[0008] As a further description of the above technical solution:

[0009] The driving part includes a driving motor installed in the middle of the right side of the upper end of the frame, a turntable installed at the lower end of the driving motor, a transmission slide column rotatably installed on the turntable and away from the center of the circle, and an O-shaped slide buckle fixed in the middle of the upper end of the mounting frame and corresponding to the transmission slide column.

[0010] As a further description of the above technical solution:

[0011] The quick-install part includes a limiting buckle fixed integrally at the lower end of the mounting frame, a brush seat installed at the upper end of the brush plate and buckled with the limiting buckle, and a locking member arranged at the middle of the right end of the limiting buckle.

[0012] As a further description of the above technical solution:

[0013] The locking member comprises an inner thread sleeve fixed at the middle part of the right end of the limiting buckle and communicated with the limiting buckle, and an outer stud installed on the inner side of the inner thread sleeve through threaded engagement and with the inner end abutting against the brush seat.

[0014] As a further description of the above technical solution:

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] 1. In the utility model, the original flushing mechanism is scientifically and rationally improved, and a mounting frame, an O-shaped slider, a guide column, a driving motor, a turntable and a transmission slider are added to the frame. When the driving motor is working, it can drive the turntable to rotate at a constant speed, and the transmission slider on the turntable will rotate at a constant speed accordingly. Under the contact transmission action between the transmission slider and the O-shaped slider, the mounting frame as a whole can reciprocate along the Y-axis direction on the frame, thereby driving the brush plate to reciprocately wash the belt body. This structure can perform auxiliary brushing treatment on the belt body during the flushing process, can effectively remove stubborn impurities adhering to the belt body, and effectively reduce the occurrence of problems such as extrusion damage of the belt body and abnormal operation of the filter press, thereby improving the flushing effect of the automatic flushing mechanism.

During actual use, the belt will move at a uniform speed under the spray bar 2 and the brush plate 5. When the electromagnetic control valve 202 is opened, the flushing liquid It will enter the spray bar 2 and be evenly sprayed onto the belt body in the form of a water curtain through multiple atomizing nozzles 201 to rinse the belt body. At the same time, the driving motor 4 can drive the turntable 401 to rotate, and the transmission slide post 402 on the turntable 401 will rotate at a uniform speed. Under the contact transmission action between the transmission slide post 402 and the O-shaped slider 301, the mounting frame 3 as a whole can be reciprocated along the Y-axis direction on the frame 1 through the guide column 302, thereby driving the brush plate 5 to reciprocate and wash the belt body.
