Description

Technical Field

[0001] The utility model belongs to the technical field of sludge dehydration, and more specifically relates to a belt-type sludge deep dehydrator. Background Art

[0002] The sludge high-pressure belt deep dewatering machine is an advanced sludge dewatering equipment, mainly used for sludge dewatering in municipal sewage treatment plants, industrial wastewater treatment plants, and other places. Its working principle is to use high-pressure belt dewatering technology to deeply dewater wet sludge with a high moisture content, reducing the moisture content of the sludge to a low level, thereby achieving sludge reduction and harmless treatment.

[0003] In the prior art, the authorized publication number "CN217230532U" discloses a "sludge high-pressure belt deep dewatering machine"; it includes a main frame and upper and lower filter belts, the main frame is provided with a feed module, a filter press module and a discharge module, the filter press module is arranged between the feed module and the discharge module; the feed module includes a uniform distribution mechanism, the uniform distribution mechanism is arranged above the lower filter belt, and a feed port is arranged above the uniform distribution mechanism; the filter press module includes a pressure roller and a pressing mechanism, the pressing mechanism includes a low-pressure zone and a high-pressure zone; a plurality of pressure rollers are distributed in the low-pressure zone and the high-pressure zone, the large-diameter pressure roller and the small-diameter pressure roller are both arranged in the filter press module through bearings, and the upper and lower filter belts are respectively wound on the pressure roller, the large-diameter pressure roller and the small-diameter pressure roller; the discharge module includes a discharge device and a flushing mechanism, the working surface of the flushing mechanism covers the working surface of the upper and lower filter belts. The utility model solves the problems of the existing sludge dewatering equipment, such as complex process flow, poor dewatering effect, low sludge processing capacity, high investment cost, high labor cost and high operating cost.

[0004] The above-mentioned "a sludge high-pressure belt deep dewatering machine" still has some disadvantages. For example, during the use of the existing high-pressure belt sludge machine, during the process of contact and squeezing dewatering between the sludge and the filter belt, sludge residue will form on the surface of the filter belt. The residual sludge moves along the surface of the moving filter belt. The residual sludge will occupy the surface space of the filter belt, reducing the new sludge processing capacity and reducing the processing efficiency of the dewatering machine. At the same time, the residual sludge will cause the filter belt to be blocked in the subsequent dewatering process, affecting the water permeability of the filter belt and making the dewatering effect worse. At the same time, the angle position of the pressing filter belt is relatively fixed and difficult to adjust, and its practicality is low.

[0005] For this reason, a belt-type sludge deep dewatering machine is proposed here to solve the above-mentioned problems. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the utility model provides a belt-type sludge deep dewatering machine to solve the problem proposed in the above background technology that the residual sludge will occupy the surface space of the filter belt, reduce the new sludge processing volume, and reduce the processing efficiency of the dewatering machine. At the same time, the residual sludge will cause the filter belt to be blocked during the subsequent dewatering process.

[0031] In this embodiment, a discharge device 10 is provided on one side of the frame 3 .

[0032] In a further preferred embodiment of the present invention, Figures 1 to 3 As shown, after the dehydration process is completed, the dehydrated mud cake can be unloaded from the filter press belt 6 and sent out to one side of the frame 3 using the unloading device 10.

[0033] The specific usage and function of this embodiment are as follows: in the daily operation of the new high-pressure belt-type sludge deep dewatering machine, the sludge material that needs to be dewatered first enters the frame 3 and is firstly arranged by the mud spreading device 9 to evenly spread the sludge on the surface of the filter press belt 6, so as to provide a uniform sludge layer for the subsequent dewatering process. The mud spreading device 9 can be stably supported by the support plate component 15. After the sludge is evenly spread, it will be squeezed along the surface of the filter press belt 6. At the same time, the setting of the redirecting roller system 11 can be used to guide the filter press belt 6 to form a closed loop inside the frame 3 to achieve continuous dewatering of the sludge. At the same time, in the process of liquid squeezing the sludge through the filter press belt 6, the water receiving tray component 12 can be used to collect wastewater generated in the dehydration process to prevent wastewater from overflowing and protect the environment. The external machine shield body 18 can protect the internal components from the influence of the external environment and reduce the noise during the operation of the equipment.

[0034] At the same time, during the operation of the filter press belt 6, the filter press belt 6 will move through the inner sides of the upper flushing device 2 and the lower flushing device 13. The inner sides of the upper flushing device 2 and the lower flushing device 13 are both provided with nozzles and scrapers. The nozzles and scrapers on the inner sides of the upper flushing device 2 and the lower flushing device 13 can be used to flush the sludge on the surface of the filter press belt 6. The upper flushing device 2 and the lower flushing device 13 can be connected to supply water, and the upper flushing device 2 and the lower flushing device 13 can be connected to the pipe system 17. By flushing the upper and lower surfaces of the filter press belt 6 respectively, the residual sludge and impurities can be removed, thereby ensuring the cleanliness and dehydration effect of the filter press belt 6.

[0035] And in the process of operation of the squeeze filter belt 6, the signal transmission component 7 can be used to monitor the operating status of the equipment in real time, and transmit relevant information to the control system. The control system can adjust the upper correcting component 5 and the lower correcting component 14 to work. The upper correcting component 5 and the lower correcting component 14 can be used to correct the deviation of the squeeze filter belt 6 during operation, ensure the stable operation of the squeeze filter belt 6, and improve the dehydration efficiency. At the same time, the control system can adjust the upper adjusting component 8 and the lower adjusting component 16. After the upper adjusting component 8 and the lower adjusting component 16 are started, the squeeze filter belt 6 is driven to move. The tension of the squeeze filter belt 6 can be adjusted to ensure that the squeeze filter belt 6 operates in the best state and improve the dehydration effect.
