A continuous disc type separation spinning dewatering machine without net

Abstract

This invention relates to a screenless continuous disc-type separator, spun mill, and dewatering machine, comprising a base, main shaft, differential, drum, separation cylinder, auger spun mill device, and slag discharge device. The main shaft is mounted on the base, and a motor drives the differential, main shaft, drum, and separation cylinder to rotate. The drum contains an impeller and two separation discs, and the separation cylinder contains one separation disc. An auger spun mill device is mounted around the drum, and a slag discharge device is located below the auger spun mill device. The inlet and outlet pipes are located below and above the main shaft. During operation, the liquid to be processed enters the main shaft through the inlet pipe and then enters the drum. The impeller and two separation discs separate the highly concentrated and dewatered slag at high speed, which is then thrown towards the slag outlet on the peripheral cylinder wall. The auger spun mill device then presses the slag out into the slag collection tank, and the slag is scraped out of the machine by a scraper. The purified liquid after concentration and separation in the drum enters the separation cylinder and is separated again by the first separation disc. The separated purified water flows upward into the main shaft and is then discharged from the machine through the upper outlet pipe.

Description

Technical fields:

[0001] This technology relates to a solid-liquid separation technology, belonging to the field of wastewater and solid-liquid separation and dewatering. Technical Background

[0002] Currently, the most commonly used disc centrifuges rely on the centrifugal force generated by the high-speed rotation of discs in the drum to separate the slurry into solids and liquids. When the sludge accumulates to a certain height in the sedimentation tank around the drum, it is discharged periodically through a complex sludge removal device. This structural design has the following disadvantages: First, the discharged sludge has a water content of over 95%, making it impossible to directly recycle; second, when the sludge adhering to the inner cavity of the drum and the surface of each disc reaches a certain thickness, normal operation is impossible. At this point, all the discs inside the drum must be manually removed, cleaned, and reinstalled before normal operation can resume, which is time-consuming, labor-intensive, and cannot be used continuously.

[0003] Furthermore, the horizontal screw centrifuges commonly used in the market rely on the centrifugal force generated by the high-speed rotation of the drum to separate the slurry material into solids and liquids. The sludge around the drum is scraped to one end by the spiral blades, and then forcibly squeezed out of the machine by the conical spiral blades that taper from large to small at that end. The biggest drawback of this conical spiral blade design is that the sludge, which has achieved its best dewatering effect with the maximum centrifugal force generated at the maximum radius around the drum, is squeezed from the periphery towards the center of the drum. During this process, the centrifugal force is smaller at the center of the drum, resulting in a poorer dewatering effect. Therefore, the moisture content of the sludge squeezed towards the center increases from low to high, resulting in a very high moisture content in the sludge produced by this machine. When treating municipal sludge and tailings, the moisture content of the sludge produced by this machine can reach 75-80%. This high moisture content of the sludge greatly increases the difficulty and cost of subsequent drying treatment. Summary of the Invention:

[0004] To address the aforementioned technical problems, the purpose of this invention is to provide a screenless continuous disc-type spun ladle dewatering machine; employing the latest patented technology; an automatic scraper bar is installed between each separation disc in the drum, which can automatically scrape off the sediment adhering to each separation disc in the drum, thereby improving the separation effect;

[0005] The slag discharge method is designed to directly and continuously spin-press the outermost layer of slag with the lowest moisture content, which has been thrown onto the outermost wall of the drum after dewatering, out of the machine. Therefore, the moisture content of the discharged slag is very low, less than 20%, eliminating the need for further dewatering with a filter press. The slag can be directly recycled. According to information from "Deep Exploration Big Data," no single meshless mechanical device in the world can currently meet the stringent requirement of "continuous slag discharge with a moisture content of less than 20%." This demonstrates that the dewatering technology of this patent has reached a globally leading level.

[0006] It has a wide range of applications and is suitable for all places that require continuous solid-liquid separation and dehydration. It can completely replace the existing belt and plate and frame filter presses on the market. It has a large production capacity and can operate continuously.

[0016] Beneficial effects:

[0017] The present invention provides a screenless continuous disc separation spinning dewatering machine that overcomes the shortcomings of various separation dewatering machines on the market that cannot continuously discharge slag, have too high slag moisture content, and require manual cleaning of sediment on the separation discs.

[0018] The present invention provides a screenless continuous disc-type spun ladle dewatering machine; the results of multiple laboratory prototype tests are as follows:

[0019] 1. No filter screen is required. It integrates the functions of a filter press and a filter screen, while being highly efficient and energy-saving, greatly reducing operating costs.

[0020] Second, because automatic scraper bars are installed between the separation discs in the drum, the sediment stuck to the separation discs in the drum can be automatically scraped off, thereby greatly improving the separation effect.

[0021] Third, because the slag discharge method can directly and continuously spin-press the outermost layer of slag with the lowest moisture content, which is thrown onto the peripheral cylinder wall inside the drum, out of the machine, the moisture content of the discharged slag is very low, as low as 20%, eliminating the need for further dewatering with a filter press.

[0037] Working principle and process:

[0038] During operation, motor 2 64 is first started, which drives the differential pulley 32, differential 31, drum 49, separator cylinder 89 and protective cover 2 to rotate synchronously via belt. Then, motor 1 34 is started, which drives the sun gear pulley 60 to rotate the differential drive disc 30 and main shaft 1 via belt. Then, the main shaft 1 drives the impeller 11 and separator disc 2 78 to rotate ahead of the drum 49. After that, the main shaft 1 drives the drive disc 47, large auger cylinder 50, large auger blades 51 and separator disc 1 68 to rotate ahead of the separator cylinder 89. The main shaft 1 on the separator cylinder 89 drives the large gear 3 to rotate, and the large gear 3 drives the small gear 1 42, auger shaft 98 and small auger blades 92 to rotate.

[0039] Then, the wastewater to be treated is pumped into the main shaft 1 through the lower inlet pipe 66 by an external water pump. From bottom to top, it flows through the inlet hole 13 and into the drum 49 and separation disc 78 from below the impeller 11. Due to the high-speed rotation of the drum 49, the sediment in the wastewater entering the drum 49 and separation disc 78 is highly concentrated and thrown at high speed towards the periphery of the drum 49 for solid-liquid separation and dewatering. At this time, the sediment adhering to the upper and lower end faces of the separation disc 78 is scraped off by the scraper rod 80 and thrown towards the wall of the separation disc 89 for dewatering. After the initial high-concentration and dewatering in the drum 49, the sediment is cleaned and purified. Wastewater enters separation plate 2 78 through inlet hole 4 79 and undergoes separation. After being separated, it flows upwards from outlet hole 3 77 into inlet hole 4 75, then through inlet hole 3 74 into the lower part of diversion plate 73, flowing outwards into separation cylinder 89. Once in separation cylinder 89, the wastewater enters each separation plate 1 68. At this point, due to the high-speed rotation of separation cylinder 89 by main shaft 1, the wastewater in each separation plate 1 68 undergoes a second solid-liquid separation. Simultaneously, the sediment adhering to the upper and lower surfaces of separation plate 1 68 is scraped off by scraper rod 1 72 and thrown against the cylinder wall of separation cylinder 89 for detachment. Water, after high-speed separation and dewatering, and sediment pass through the upper mesh holes of the large auger cylinder 50 and are thrown towards the inner wall of the separation cylinder 89. The highly dewatered sediment on this inner wall is then spun downwards by the large auger blades 51 driven by the main shaft 1 to the slag outlet 83 and enters the slag discharge trough 102 in the impeller 11. It is then thrown together with the original sediment in the slag discharge trough 102 towards the periphery of the rotating drum 49 for further dewatering. The clean water that enters from the separation disc 68 and has been dewatered again flows upwards from the water outlet 69 to below the upper end cover 8 of the separation cylinder, and then flows into the main shaft from the water outlet 7 in the main shaft 1. The sludge flows upward through the upper outlet pipe 37 and is discharged from the machine. The fully dewatered sludge is then thrown at high speed by the rotating drum 49 and directed by the impeller 11 to the periphery. Guided by the guide plate 93, it passes through the sludge outlet 95 and is spun into the small auger cylinder 48. The small auger blades 92 on the auger shaft 98 then spun downwards, squeezing the sludge into the gap between the lower end of the small auger cylinder 48 and the movable sludge baffle 25, where it is pushed out and falls into the sludge collection trough 24. Finally, the reduction motor drives the scraper plate 22 to rotate, scraping the sludge in the sludge collection trough 24 to the discharge port 57, where it falls into the sludge discharge hopper 58 and is discharged from the machine. This completes one solid-liquid separation and dewatering process of the wastewater slurry.
