Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sludge treatment, and particularly relates to an upper water discharge device for a sludge conditioning machine. BACKGROUND

[0002] Sludge incineration is a process of sludge treatment, which uses an incinerator to heat and dry dewatered sludge, and then oxidizes the organic matter in the sludge at high temperature to make the sludge into a small amount of ash. Before the sludge is burned in the furnace, the sludge needs to be dewatered under the premise that the organic matter of the sludge is not lost, to ensure that the sludge has enough calorific value to meet the requirements of the boiler for the fuel burned in the furnace. Traditional sludge dewatering methods include natural drying method, granulation dewatering method and mechanical dewatering method.

[0003] Publication No. "CN113730996A" discloses "a high-efficiency dewatered sludge calorific value conditioning machine", which cooperates between the sealing structure, the upper layer filter cloth automatic telescopic mechanism, the active conveying mechanism and the auxiliary feeding mechanism, so that the water content of the extruded sludge is greatly reduced, and the sludge quickly separates from the sticky phase area. Compared with traditional equipment, the calorific value conditioning machine has no sludge adhesion, reduces the equipment failure rate and improves the equipment processing efficiency.

[0004] The above-mentioned prior art still has the following disadvantages:

[0005] When the sludge is extruded and dewatered, only the extruded water is discharged from the lower side. When the lower part of the sludge reaches the "dry and brittle" state, the water content of the upper part of the sludge is still high, which leads to poor dewatering effect of the sludge. If the pump suction water is used to extract the extruded water from the upper side, the structure is too complex, and the installation of the pump and the water pipe also needs to be considered, which has poor use effect.

[0006] To solve the above problems, we design an upper water discharge device for a sludge conditioning machine. SUMMARY

[0041] Embodiment:

[0042] When the sludge is dewatered, the sludge is first fed into the conveying belt 8 from the feeding port 1. Under the action of the conveying belt 8, the sludge is conveyed to the right. The width of the conveyed sludge is limited by the lateral baffles 2 to prevent the sludge from falling off the conveying belt 8, facilitating subsequent extrusion dewatering. At the same time, the sludge conveyed on the conveying belt 8 is flattened under the action of the mud pressing roller 7, limiting the height of the sludge and facilitating subsequent extrusion dewatering.

[0043] When the sludge is transported to the high pressure section 4, the small oil cylinder 10 is started to push the side sealing plate 13 to move downward, and the upper filter cloth 20 is moved downward to press the upper side of the sludge on the conveying belt 8 until the bottom of the side sealing plate 13 abuts against the rubber pad 21 to form a sealing to prevent the sludge from leaking from the side;

[0044] Then the large oil cylinder 5 is started to push the upper pressing plate 11 to move downward through the large oil cylinder 5, and then the drainage plate 12 is moved downward to press the upper surface of the upper filter cloth 20, and as the large oil cylinder 5 continues to extend, the upper pressing plate 11 and the drainage plate 12 press the sludge, and the lower pressing plate 16 and the polymer plate 15 support and limit the conveying belt 8, so as to achieve the purpose of pressing the sludge;

[0045] During the process of pressing the sludge, the water squeezed out from the bottom of the sludge flows downward through the holes on the surface of the conveying belt 8, and the water-permeable holes on the surfaces of the polymer plate 15 and the lower pressing plate 16, and flows into the water receiving tray 17, and the water squeezed out from the top of the sludge flows upward through the drainage holes 23 on the surface of the drainage plate 12 and flows into the water storage tank 24, and flows to the first flow guide hole on the surface of the side sealing plate 13, and under the cooperation of the first flow guide hole and the second flow guide hole, the squeezed water flows into the rectangular pipe 14, and finally flows downward through the strip-shaped hole at the bottom of the rectangular pipe 14 and the water passing holes on both sides of the surface of the upper filter cloth 20 to the polymer plate 15 and the lower pressing plate 16, and flows into the water receiving tray 17 on the lower side through the water-permeable holes on the surfaces of the polymer plate 15 and the lower pressing plate 16, and after the sludge is dewatered, the sludge is transported to the discharge port 6 through the conveying belt 8 for discharge, and the above dewatering operation is repeated to realize the circulation of the sludge feeding, dewatering and discharging.

[0046] Compared with the prior art, the present application first presses the side sealing plate 13, and then presses the upper pressing plate 11. Due to the pressure, the water at the lower part of the sludge flows into the water receiving tray 17 through the water permeable holes on the surface of the polymer plate 15 and the lower pressing plate 16, the water at the upper part of the sludge is squeezed into the drain hole 23 and flows into the water storage groove 24, and then flows to the side sealing plate 13 on the front and rear sides of the water storage groove 24, flows into the rectangular tube 14 welded on one side of the side sealing plate 13 through the first and second flow guide holes, and finally flows out to the upper filter cloth 20 through the strip-shaped holes at the bottom of the rectangular tube 14, and under the action of the water permeable holes on the front and rear sides of the surface of the upper filter cloth 20, the water flowing out of the rectangular tube 14 flows down to the polymer plate 15 between the side sealing plate 13 and the gantry 9, and finally, under the action of the water baffle 19, in combination with the water permeable holes on the surface of the polymer plate 15 and the lower pressing plate 16, the water squeezed out from the upper part of the sludge flows into the water receiving tray 17 from both sides of the high-pressure section 4, achieving the purpose of simultaneous drainage of the bottom and top of the sludge, solving the problem that in the existing sludge dewatering process, only water is drained from the bottom, and when the lower part of the sludge reaches a "dry and brittle" state, the upper part of the sludge still has a high water content, and the sludge dewatering effect is poor, effectively improving the sludge dewatering effect and dewatering efficiency, and the structure is simple, easy to install, and does not need to use a pump to suck water, avoiding many troubles and facilitating the use of sludge dewatering.

[0047] It should be further pointed out that the mounting structure, connection mode or setting mode of each component in the present application are common mechanical modes, as long as the beneficial effects can be achieved, and the large oil cylinder 5 and the small oil cylinder 10 can be purchased on the market, and the person skilled in the art can install and use them according to requirements.
