Second embodiment:

referring to fig. 7, in the dewatering press for sludge disposal according to the first embodiment, in the actual use process, especially in the process of pressing down sludge by the pressing plate 19, the sludge at the bottom can enter the blow-down hole in the bottom surface of the collecting box 15, which easily causes the blockage of the blow-down hole, so that the pressed sewage and sludge cannot be completely discharged, the dewatering effect is affected, in addition, after the compacted sludge is pushed onto the surface of the conveyor belt 2, the sludge is easily entered into the ventilation holes 3 on the surface of the conveyor belt 2, so that part of hot air cannot be discharged from the ventilation holes 3, and the dewatering and drying efficiency of the sludge is affected, so as to solve the problems:

When the device is used, sludge is compacted into a square by the pressing plate 19 and pushed out by the pushing plate 34, the sealing door 30 and the pushing plate 34 are reset by the third electric push rod 32 and the hydraulic rod 36 respectively to enable the collecting box 15 to be in a closed state, the second electric push rod 17 is used for driving the conical column 18 to move downwards and simultaneously pressing the pressing plate 19 downwards, in the process, the gas flow sensor 1502 is used for detecting the gas flow discharged from the detecting tube 1501, when the gas flow sensor 1502 detects that the gas flow discharged from the detecting tube 1501 is larger than a set threshold value, the pollution discharge hole on the bottom surface of the collecting box 15 is actively judged to be blocked, at the moment, on the basis that the bottom surface of the conical column 18 is always kept correspondingly attached to a round material hole, the second electric push rod 17 is enabled to slowly shrink and rapidly stretch out, and then make clamp plate 19 reciprocate fast from top to bottom under compression spring 20 effect, this in-process, through the slow shrink of second electric putter 17, clamp plate 19 upwards slow motion, and utilize the blowdown hole in collecting box 15 bottom to bleed into collecting box 15, the in-process of stretching out fast, clamp plate 19 is with the quick discharge of gas that draws in, in the exhaust process, can utilize the air current of ejecting to discharge the collecting box 15 of the mud that blocks up in the blowdown hole, realize the clear stifled of blowdown hole, the mud that clears up falls into and bear frame seat 26 in, and the baffle 2605 of bearing frame seat 26 one side is in the inclined condition this moment in order to be convenient for the discharge of mud sewage, after the blowdown hole clearance finishes, gas flow sensor 1502 detects that the gas flow of detecting pipe 1501 exhaust is less than the threshold value, toper post 18 resets and breaks away from clamp plate 19.

However, because the viscosity of the sludge and sewage is greater, the sludge is easy to adhere to the bottom of the bearing frame seat 26 and is difficult to discharge, therefore, after the compacted sludge blocks are pushed onto the conveyor belt 2, the electromagnet 201 is started, the electric roller 4 drives the conveyor belt 2 to run anticlockwise, the electromagnet 201 moves along with the conveyor belt 2, the electromagnet 201 is separated from the metal seat 2608, the metal seat 2608 is adsorbed by the magnetism of the electromagnet 201, and simultaneously the metal seat 2608 moves along with the conveyor belt 2 for a certain distance in a linear manner, in the process, the metal seat 2608 drives the transmission plate 2603 to slide through the push rod 2607, the transmission spring 2604 is compressed, the transmission plate 2603 slides and simultaneously discharges the sludge attached to the bottom of the bearing frame seat 26, when the electromagnet 201 reaches the end part and starts to move towards the upper side of the electric roller 4, the dragging force generated by the conveyor belt 2 overcomes the magnetism of the electromagnet 201 to the metal seat 2608, the electromagnet 201 is forced to be separated from the metal seat 2608, and the transmission plate 2603 is quickly reset under the action of the transmission spring 2604 after the separation, and the surface of the conveyor belt 2 is embedded with a plurality of electromagnet plates at equal intervals, so that the reciprocating position of the electromagnet 201 and the sludge blocks can be driven to stop to be driven by the reciprocating position of the electric roller 4, and the sludge can be driven to the reciprocating position of the electric roller 2 and the reciprocating frame seat is closed, and the sludge can be driven and the position and the reciprocating position and the position of the electric roller can be closed.

In addition, in the process of conveying the sludge blocks compacted by the pressing plate 19 to the surface of the conveyor belt 2 for heating and drying, as the sludge is still in a relatively wet state and has relatively strong fluidity, the sludge is easy to block in the air holes 3 on the surface of the conveyor belt 2, so that partial air flow generated by the air heater 6 cannot contact with the sludge blocks, and the dehydration and drying efficiency of the sludge is affected.

Therefore, when the air pressure of the air outlet of the air heater 6 is detected to be greater than the set threshold value by the air pressure sensor 601, the air holes 3 are actively judged to be blocked, at this time, the sludge on the conveyor belt 2 is dismounted firstly, and the conveyor belt 2 is driven to operate by the electric roller 4, the baffle 2605 is driven to rotate by the on-off motor 2606, the baffle 2605 is enabled to be in a vertical state to seal the end part of the bearing frame 26, at this time, the bearing frame 26 is in a sealed state, the collecting box 15 is enabled to be kept in a sealed state by the sealing door plate 30 and the push plate 34, the bearing frame 26 is communicated with the inside of the collecting box 15 through the drain hole at the bottom of the collecting box 15, meanwhile, the conical pillar 18 is enabled to be attached to the circular feed inlet in the middle of the pressing plate 19, and the second electric push rod 17 is enabled to reciprocate rapidly, during this process, the second electric push rod 17 is pushed to slide by the air flow, the driving plate 2603 is stretched, the second electric push rod 17 is enabled to reset when the second electric push rod 17 contracts in a trace, the end part of the conveyor belt 2603 is enabled to reciprocate by the air flow, the second electric push rod 2609 is enabled to reciprocate, meanwhile, the brush 2609 is enabled to reciprocate by the electric push rod 17 to reciprocate, and the air flow is enabled to reciprocate, and the air hole is enabled to rotate when the air heater 2606 is enabled to rotate, and the air heater is enabled to rotate in a state when the air heater is enabled to rotate in a trace state, and the air heater is enabled to rotate, and the air heater is enabled to rotate and the air is enabled to rotate, and the air is enabled to rotate and is reciprocally and to rotate, and is kept in contact with air.
