One end of the conveying line 5 is arranged at the bottom side of the right end of the forming pressing rotating plate 2, which is beneficial to the receiving and conveying of the cake-shaped sludge. A lower pushing and discharging plate 6 for pushing and pneumatically discharging the sludge cake formed in the pneumatic forming ring seat 3 is erected on the conveying line 5. The cake-shaped sludge inside the pneumatic forming ring seat 3 can be pushed to the vertical upper end of the conveying line 5 for lower pushing and discharging. An upper feeding box 7 for storing and feeding the dried and pulverized sludge to the pneumatic forming ring seat 3 is arranged on one side of the surface of the sludge pressing table 1. The separated and dried sludge can be conveyed into the inside of the upper feeding box 7 for storage and continuously drawn and fed into the pneumatic forming ring seat 3 for pressing into a cake shape.

[0018] The surface of the forming and pressing rotating plate 2 is evenly provided with cylinders A8, which push the pneumatic forming ring seat 3 to move for discharging the cake-shaped clay. The piston rod of the cylinder A8 is fixed at one end of the pneumatic forming ring seat 3, realizing continuous discharging treatment of the cake-shaped clay. And the pneumatic forming ring seat 3 fits on the surface of the forming and pressing rotating plate 2. The feeding rollers 9 rotating on both sides in the inner groove of the conveyor line 5 drive the conveyor belt 10 to transmit. And the feeding rollers 9 are rotated by an external motor. And the speed of the rotation of the feeding rollers 9 is controlled by the controller in the external PLC control system. And all the control components in this press are controlled by the PLC control system, so as to realize continuous pressing and forming of the cake-shaped clay. The conveyor belt 10 for discharging and conveying the pressed clay blocks is driven on the feeding rollers 9, and the cake-shaped clay can be conveyed by the conveyor belt 10. And one end of the conveyor line 5 is provided with a square frame 11, and the cylinder B12 can be fixed at the inner top end of the square frame 11 and located vertically above the conveyor belt 10. The cylinder B12 is provided at the inner top end of the square frame 11, pushing the lower pushing and discharging plate 6 to reciprocate downward for the work of lower pushing and discharging. And the piston rod of the cylinder B12 is fixed at the center position of the end of the lower pushing and discharging plate 6. Behind the end face of the forming and pressing rotating plate 2, there is a mounting frame 13 installed on the clay pressing table 1. The cylinder C14 can be fixed at the middle of the inner top end of the mounting frame 13 and is vertically opposite to the center point of the pneumatic forming ring seat 3. The cylinder C14 is provided at the inner top end of the mounting frame 13, and the piston rod of the cylinder C14 is fixed at the center position of the upper end face of the pneumatic forming pressing plate 4. The cylinder C14 can continuously push the pneumatic forming pressing plate 4 to press the clay into a cake shape according to the speed of the forming and pressing rotating plate 2 under the control of the PLC control system.

[0019] At the front end of the forming and pressing rotary plate 2 and on the upper end surface of the sludge pressing table 1, there is a fixing frame 15. One end of the upper part of the fixing frame 15 is bent and extended to the upper end of the forming and pressing rotary plate 2, and a blanking bellows 16 is installed. The blanking bellows 16 is vertically arranged above the pneumatic forming ring seat 3 on the forming and pressing rotary plate 2. The vertical distance between the outlet end of the blanking bellows 16 and the pneumatic forming ring seat 3 is set to be short, which is beneficial to accurately injecting the crushed sludge into the inside of the pneumatic forming ring seat 3. The blanking bellows 16 is connected to a feeding pump 17 through a pipeline. The output end of the feeding pump 17 is connected to a discharging pipe fitting, and the discharging pipe fitting is connected to the input port of the blanking bellows 16. The input end of the feeding pump 17 is connected to a feeding pipe, and one end of the feeding pipe is connected to one side surface of the feeding box 7 for continuously extracting and conveying the material. And an electric control valve is installed on the discharging pipe fitting, which is beneficial to controlling the feeding amount and speed. The input end of the feeding pump 17 is connected to the feeding box 7 to achieve the effect of continuous feeding. At the center position of the upper end surface of the sludge pressing table 1, there is a servo motor 18. The rotation angle stop of the servo motor 18 is controlled by an external PLC control system, which is beneficial to the press to continuously press and form the sludge. The rotating shaft of the servo motor 18 is fixed at the center position of the lower end surface of the forming and pressing rotary plate 2. At the bottom of the forming and pressing rotary plate 2, there is an annular support member 19 fixed on the sludge pressing table 1 to support the forming and pressing rotary plate 2, which can ensure the horizontal stability of the forming and pressing rotary plate 2 when it is subjected to a downward pressure and prevent it from tilting.

[0020] Specifically, during use, the press is connected to an external PLC control system for control. The control system commands the feeding pump 17 to convey the dried and pulverized oily sludge in the feeding tank 7 to the feeding horn pipe 16 through a material pipe. The feeding horn pipe 16 discharges the dried and pulverized oily sludge into the pneumatic forming ring seat 3. After the feeding is completed, the control system closes the control valve. At this time, the control system commands the servo motor 18 to drive the forming and pressing rotating plate 2 to rotate. The rotation of the forming and pressing rotating plate 2 causes the pneumatic forming ring seat 3 to rotate accordingly. While rotating, the next pneumatic forming ring seat 3 rotates to the vertical bottom end of the feeding horn pipe 16 for injecting the dried and pulverized oily sludge. Moreover, the forming and pressing rotating plate 2 continuously drives the pneumatic forming ring seat 3 to continue rotating. At this time, the first pneumatic forming ring seat 3 filled with the dried and pulverized oily sludge rotates to the bottom of the pneumatic forming pressing plate 4. The cylinder C14 is used to push the pneumatic forming pressing plate 4 downward into the dried and pulverized oily sludge in the pneumatic forming ring seat 3 to press it into a cake-shaped oily sludge and then retract. Then, the forming and pressing rotating plate 2 drives the cake-shaped oily sludge in the pneumatic forming ring seat 3 to continue rotating to the position corresponding to the conveyor line 5. When the rotation stops, the cylinder A8 is used to push the pneumatic forming ring seat 3 to move above the vertical position of the conveyor line 5. At this time, the control system commands the cylinder B12 to push the lower pushing and discharging plate 6 downward into the pneumatic forming ring seat 3 to push the cake-shaped oily sludge inside it downward to separate from the pneumatic forming ring seat 3 and drop onto the conveyor belt 10 on the conveyor line 5 for discharging and conveying. Subsequently, the pneumatic forming ring seat 3 moves back to the initial state and continues to be driven by the forming and pressing rotating plate 2 to rotate for injecting the dried and pulverized oily sludge and gradually performing pressing forming and downward pushing and discharging output. Through the above operations, the forming and pressing rotating plate 2 can be repeatedly rotated to drive the pneumatic forming ring seat 3 to rotate, so as to synchronously and continuously perform operations such as feeding, pressing forming, and pneumatic discharging, enabling the press to continuously press the dried and pulverized oily sludge into shape, effectively ensuring the continuity and efficiency of the work.
