Description

Technical Field

[0001] This invention relates to the field of sludge dewatering equipment technology, and in particular to a high-efficiency integrated sludge dewatering and drying machine and a dewatering and drying method. Background Technology

[0002] To ensure that wastewater meets the standards for discharge into a water body or for reuse, it must undergo dewatering and purification treatment. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people. Sludge is a solid sediment produced during the water and wastewater treatment process, and it still contains a significant amount of liquid.

[0003] Reducing the water content in sludge and silt has become a key technology for volume reduction. If the water content of sludge from a wastewater treatment plant is reduced from 80% to 60%, its volume will be reduced by half.

[0004] However, current sludge dewatering equipment mostly uses mechanical extrusion or drying after adding flocculants for rapid dewatering. However, the internal moisture content is still high after processing, requiring repeated dewatering. Its dewatering efficiency is low and cannot meet the moisture content requirements in sludge treatment. In view of the above, other more efficient dewatering technologies need to be considered. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency integrated sludge dewatering and drying machine and dewatering and drying method. This addresses the problem that current sludge dewatering equipment often uses mechanical extrusion or drying after adding flocculants for rapid dewatering.

Under the action of the liquid sludge, the rotating blades rotate, driving the horizontal rotating shaft to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear, through gear meshing, drives the second bevel gear to rotate, which in turn drives the vertical rotating shaft to rotate.

It is squeezed and conveyed by the screw conveyor roller for dehydration, and dried and dehydrated by the heating jacket. After being filtered through filter screen two, it is discharged through the drain pipe. The sludge is conveyed to the drying box through the conveying pipe. The dryer is activated and high-temperature gas is added to the drying box. The rotating blades are used for stirring. The high-temperature gas dries and dehydrates the sludge. Finally, it is discharged through the discharge pipe.

[0023] The beneficial effects of this invention are:

[0024] Equipped with a mobile extrusion crushing component, the sludge is extruded and tumbled by a movable plate that can move up and down. After extrusion, the water in the sludge is filtered through a filter screen and filter cotton and then quickly discharged through a drain pipe, greatly improving the sludge dewatering efficiency. At the same time, a negative pressure exhaust system is used to create a pressure difference between the inner and outer spaces of the installation sleeve, allowing wastewater to flow out quickly and increasing the sludge dewatering speed. The sludge is also crushed by stirring blades and conical spiral blades, allowing the sludge to react quickly with flocculants to produce flocculation. The sludge is then conveyed, extruded, and heated for dewatering by the extrusion dewatering component, making it less likely to contain water and more effective in dewatering. Finally, the sludge is tumbled and dried by the drying component for even more thorough dewatering. Attached Figure Description

The moving plate 311 is movably sleeved on the outside of the screw 33, and the sealing box 318 is fixedly installed inside the moving plate 311. The rotating shaft 316 is movably inserted into the side wall of the sealing box 318. The rotating blade 320 is fixedly installed on the outside of the horizontal rotating shaft 316. The first bevel gear 319 is fixedly sleeved on the outside of the horizontal rotating shaft 316. The second bevel gear 321 is fixedly sleeved on the top of the vertical rotating shaft. The first bevel gear 319 and the second bevel gear 321 are meshed together. The bottom end of the vertical rotating shaft is fixedly connected to the limiting rotating plate 322.

The drying assembly 6 is set at the bottom of the workbench 1.

[0040] Specifically, by setting up a mobile extrusion crushing component 3, during use, a movable plate 311 that can move up and down is used to extrude and tumble the sludge. After extrusion, the water in the sludge is filtered through a filter screen 44 and a filter cotton 45 and then quickly discharged through a drain pipe 57, which greatly improves the sludge dewatering efficiency. At the same time, a negative pressure air extraction system is used to create a pressure difference between the inner and outer spaces of the mounting sleeve 41, which allows wastewater to flow out quickly and improves the sludge dewatering speed. Meanwhile, the stirring blades 39 and the conical spiral blades 312 are used to crush the sludge and allow the sludge to react quickly with the flocculant to produce flocculation. Then, the sludge is conveyed, extruded, and heated for dewatering by the extrusion dewatering component 5, making it less likely to contain water inside and making dewatering more effective. Finally, the drying component 6 is used for tumbling and drying dewatering, making the dewatering more thorough.

[0041] In this embodiment, the mobile crushing and extrusion assembly 3 further includes: a mounting rod 31, a top plate 32, a rotating plate 34, a motor 35, an output shaft 36, a motor 37, a sealing sleeve 38, a through hole 30, a limiting frame 315, and a limiting frame 317.

A connecting pipe is fixedly installed at the bottom of the filter box 21, and the bottom of the connecting pipe is connected to the crushing and extrusion assembly 5. An electromagnetic valve is installed inside the connecting pipe to control the flow of sludge, so that it can be discharged after being thoroughly processed by the mobile crushing and extrusion assembly 3. The mounting rod 31 is fixedly installed on the top of the filter box 21, the top plate 32 is fixedly installed on the top of the mounting rod 31, the motor 35 is fixedly installed on the top of the top plate 32, and the sealing plate is embedded inside the top wall of the filter box 21. Turning on the switch of motor 35 allows the output shaft 36 to drive the sealing plate to rotate, thereby causing the stirring blades 39 and the conical spiral blades 312 to rotate as a whole, resulting in more thorough and complete mixing, crushing, extrusion, and dewatering of the sludge.

Limiting frame 315 can limit the vertical rotating shaft, and limiting frame 317 can limit the horizontal rotating shaft 316, making the meshing between bevel gear 319 and bevel gear 321 more stable. Limiting frame 317 is movably engaged on the outside of the horizontal rotating shaft 316, and limiting frame 315 is movably engaged on the outside of the vertical rotating shaft.

[0042] The bottom of the workbench 1 is fixedly equipped with a support leg 11, and the bottom end of the support leg 11 is fixedly equipped with a foot pad 12. The front of the filter box 21 is equipped with a controller. The device is connected to an external power supply to provide power to the device. The controller is electrically connected to motor 1 35, motor 2 37, heating jacket, solenoid valve, motor 3 56, and dryer 68. The controller can be purchased directly from the market and used after being programmed and debugged by the staff. The suction pipe 48 is connected to an external negative pressure vacuum pumping system.

A heating jacket is provided on the outside of the top wall of the conveying box 51, and the bottom end of the drain pipe is connected to the inside of the top wall of the conveying box 51.

[0044] Specifically, the sludge is conveyed by a spiral conveyor roller 55, which can not only transport the sludge quickly, but also compress the sludge twice. The liquid is then filtered through a filter screen 54 and discharged into a collection box 53 and drained from a drain pipe 57.

[0046] Specifically, after filtration using filter screen 44 and filter cotton 45, it is easy to achieve rapid solid-liquid separation of sludge. Turning on the switch of the negative pressure vacuum pumping system creates a negative pressure vacuum in the space inside the installation sleeve 41, allowing liquid to quickly enter the interior of the installation sleeve 41. This also helps to prevent the filter screen and filter cotton 45 from clogging, resulting in higher drainage efficiency and facilitating rapid dewatering of sludge.

[0047] The drying assembly 6 includes a connecting rod 61, a drying box 62, a rotating shaft 63, rotating blades 64, a discharge pipe 65, a motor 66, an exhaust pipe 67, and a dryer 68.

[0048] Specifically, rotating blades 64 are used to make the sludge tumble rapidly in the drying box 62, and dryer 68 is used for rapid heating and drying, so that the sludge is not prone to moisture inside, resulting in better dewatering and drying effect. The dried steam can be discharged from the exhaust pipe 67, making the sludge dewatering rate higher. A protective net is used to prevent the sludge from splashing out. The sludge after dewatering is discharged through the discharge pipe 65.

[0049] The implementation process of the above-mentioned high-efficiency sludge dewatering and drying treatment process (i.e., the operation relationship of the above-mentioned high-efficiency sludge dewatering and drying integrated machine) is as follows: Sludge is added into the filter box 21 through the material input pipe 22, and flocculant is added into the filter box 21 through the liquid inlet pipe 23. Inorganic flocculant is added first, followed by organic flocculant; Motor 1 35 starts to drive the rotating plate 34 to rotate, and Motor 2 37 starts to drive the lead screw 33 to rotate, which drives the moving plate 311 to move up and down. Under the action of liquid sludge, the rotating blade 320 rotates, which drives the horizontal rotating shaft 316 to rotate, which drives the bevel gear 1 319 to rotate. The bevel gear 1 319 drives the bevel gear 2 321 to rotate through gear meshing, which drives the vertical rotating shaft to rotate, which drives the connecting shaft 314 to drive the stirring blade 39 and the conical spiral blade 31. 2. Rotate to stir and mix the sludge; after flocculation, the internal moisture of the sludge is filtered through filter screen 44 and filter cotton 45.

A pressure difference is formed inside and outside the sleeve 41, and the waste liquid is discharged through the water inlet 43 and the wastewater pipe 42. The solenoid valve is opened, and the sludge enters the conveying box 51 through the connecting pipe. It is squeezed and conveyed by the screw conveyor roller 55 for dewatering, and dried and dewatered by the heating jacket. After being filtered by filter screen 54, it is discharged through the drain pipe 57. The sludge is conveyed to the drying box 62 through the conveying pipe. The dryer 68 is started to add high temperature gas to the drying box 62. The rotating blades 64 are used for stirring. The high temperature gas dries and dewaters the sludge. Finally, it is discharged through the discharge pipe 65.
