It should be understood that the water pressure of the high-pressure water gun 3 should not be too high in order to avoid damaging the filter cloth. The direction of the water retaining cover 1 is the same as the direction of the water outlet of the elbow nozzle 2; the bottom of the water retaining cover 1 is provided with an opening 5 for sewage to flow out. The high-pressure water gun 3 is provided with an actuating mechanism 6 for pressing a switch of the high-pressure water gun. The bottom of the slide seat 4 is provided with a roller which is limited on a guide rail 7 extending along the left and right direction. The walking mechanism and the executing mechanism 6 are controlled by a PLC (programmable logic controller) 8. It should be understood that the slag removing device is arranged in two sets and is oppositely arranged at the front side and the rear side of the plate-and-frame filter press, so that the slag removing device is matched with the plate-and-frame filter press for use. One set of slag removing device is positioned relatively to the right, and the elbow nozzle 2 of the slag removing device discharges water towards the right; the other slag removing device is arranged at the left side relatively, and the elbow nozzle 2 of the other slag removing device discharges water towards the left side. Further, the PLC controller 8 generally controls the traveling mechanism, the actuator 6, and the servo motor described below through wired communication. The periodic stroke control is a basic function of the PLC controller 8, and can be realized by a commercially available common PLC controller 8, and the structure and principle of the PLC controller 8 are not described herein again.

In the following, an embodiment of the present invention will be described, in which the guide rails 7 are laid in parallel on one side of the plate and frame filter press. When the plate and frame filter press unloads the slag; the sliding seat 4 is pushed along the guide rail 7, so that one surface of the water retaining cover 1 facing the filter plate or the filter frame is coincided with or close to the slag removing surface of the filter plate or the filter frame.

Therefore, when the plate-and-frame filter press unloads slag, each filter plate or filter frame is moved, an operator only needs to correspondingly push the sliding seat 4 to move for a certain distance along the guide rail 7, and starts a cleaning action through the PLC 8, so that the filter plates or the filter frames can be cleaned once when the slag is unloaded. The utility model improves the automation degree and greatly reduces the labor intensity of operators. In addition, the elbow nozzle 2 is arranged on the water retaining cover 1, and when slag is removed, the water retaining cover 1 is buckled on the surface of a filter plate or a filter frame, and an opening 5 is reserved below the water retaining cover 1; can effectively avoid splashing of sludge and sewage.

It should be understood that the parameters of the PLC controller 8 are set according to the time interval for moving the filter plates and the filter frames when the filter frame press removes the sludge. When the plate-and-frame filter press unloads the slag, the PLC 8 is started, so that the slide seat 4 can synchronously move along with the movement of a block of the plate-and-frame filter press for moving the filter plate and the filter frame. Thereby further liberating the manpower, improving degree of automation.

Furthermore, the outlet end of the elbow nozzle 2 is provided with an external thread, and the water retaining cover 1 is provided with a matched threaded through hole. It should be understood that the elbow nozzle 2 is detachably connected with the water blocking cover 1, so that later maintenance or replacement is convenient.

Furthermore, a water storage tank 11 is arranged on the sliding base 4, and the water storage tank 11 is communicated with the high-pressure water gun 3 through a hose 12. It will be appreciated that, in order to reduce the load on the travelling mechanism, the pressurization system of the high-pressure water gun 3 may be integrated into the water storage tank 11 and mounted together on the carriage 4.

Furthermore, guide rings for limiting the hose 12 are arranged on the shells of the first power source 9 and the second power source 10; the guide ring has a gap that is smaller in size than the outer diameter of the hose 12.
