Description

TECHNICAL FIELD

[0001] The utility model relates to wastewater recycling treatment equipment technical field especially relates to a kind of deposition filtering equipment for scraper conveyor. BACKGROUND

[0002] The sedimentation tank is a pool cavity structure for treating cleaning wastewater and spraying wastewater generated by the scraper conveyor for directional conveying of materials such as minerals and sand. It can complete physical purification treatment of wastewater in a stationary state to separate sediment from water body under the action of its own gravity. After long-term use of the sedimentation tank, a large amount of sediment may accumulate on the bottom surface of the sedimentation tank, occupying the pool cavity space, and too much sediment may also affect the subsequent sedimentation and filtration effect. In addition, the accumulation of sediment may also be hardened, increasing the difficulty of subsequent cleaning. Currently, after using the sedimentation tank for a certain period of time, it needs to be stopped for emptying and cleaning. Usually, the staff uses a high-pressure water gun to flush the bottom of the pool, which wastes a lot of water resources again.

[0003] Currently, when the conventional scraper conveying equipment is conveying materials such as ores and sand, it usually needs to be connected to a spraying system for dust suppression and cleaning operation. However, the existing spraying wastewater is usually directly discharged, which may pollute the environment and cause loss of small-sized materials, and also increases the use of spraying water, exacerbating the waste of water resources. Although the existing sedimentation tank can recycle and filter the spraying wastewater produced by the scraper conveying equipment to facilitate the recycling of spraying wastewater and improve the water recycling capacity. However, the existing sedimentation tank cannot clean and recycle the sediment deposited on its bottom without stopping, which reduces the continuous working efficiency of the sedimentation tank. In particular, the existing scraping structure cannot efficiently transfer the sediment without emptying the pool cavity water body. Finally, although the existing siphon structure can transfer the sediment in the lower layer of the water body, it usually only covers a small range and cannot effectively transfer the sediment outside the siphon area, which cannot clean the bottom comprehensively and has poor overall cleaning efficiency. SUMMARY

The rotating plate rollers 3 can cooperate with the slag discharge pipe 4 to clean the sediment in the sedimentation tank 1 which has not been drained, thereby ensuring that the sedimentation tank 1 always has high sedimentation and filtration capacity, so as to ensure the effect and quality of wastewater filtration, facilitate continuous filtration and circulation of wastewater, ensure the water circulation capacity and effect of the water system attached to the scraper conveyor, and reduce the need for maintenance and cleaning of the sedimentation tank 1, thereby greatly improving the continuous working efficiency and capacity. The rotating plate rollers 3 can scrape the sediment, so that the inlet of the slag discharge pipe 4 is always covered by the sediment, so as to continuously and efficiently transfer the sediment by the slag discharge pipe 4.

[0034] Preferably, the slanted elastic pool wall 12 is arranged in position on the inner side of the pool shell 11 of the sedimentation pool 1 in a manner capable of effectively covering the input port of the residue discharge pipe 4 to collect the sediment separated by sedimentation.

The present application can better guide the sediment of sedimentation to collect at the bottom of the pool, so that the sediment is accumulated in the area where the residue discharge pipe 4 and the rotating plate roller 3 are located, thereby improving the efficiency and effect of the residue discharge pipe 4 for sediment transfer, and improving the cleaning speed and fullness of the pool bottom. The clear liquid output pipe 14 of the present application is located in the upper half of the pool shell 11, which ensures the self-sedimentation effect of the waste liquid in the pool cavity and effectively outputs the upper layer clear liquid.

[0035] Preferably, the two sets of rotating plate rollers 3 are longitudinally inserted on the pool shell 11 in a parallel manner. Preferably, the rotating plate roller 3 comprises a rotating shaft 31, a scraper 32, a sealing bearing 33, a speed reducer motor 34 and a mud scraping auxiliary plate 35. Further preferably, the rotating shaft 31 is rotatably and longitudinally inserted on two opposite side walls of the pool shell 11. Further preferably, the rotating shaft 31 is sleeved with two sealing bearings 33 capable of limiting the rotatable state thereof. Specifically, the sealing bearings 33 are embedded on the side walls of the pool shell 11. Preferably, a plurality of scrapers 32 parallel to the axis of the rotating shaft 31 are circumferentially and spaced connected on the shaft rod of the rotating shaft 31 within the pool shell 11. Preferably, one end of the rotating shaft 31 penetrates through the pool shell 11 and is drivingly connected with the speed reducer motor 34 mounted on the outer wall surface of the pool shell 11. Specifically, the two speed reducer motors 34 rotate in opposite directions, thereby pushing the sediments to both sides, i.e., the left side rotates clockwise and the right side rotates counterclockwise. Preferably, the plate body edge of the scraper 32 away from the rotating shaft 31 is further connected with the mud scraping auxiliary plate 35 capable of effectively pushing the sediments to move by variably expanding the plate body area by changing the plate surface included angle with the scraper 32. Further preferably, a guide sliding groove is formed on the mud scraping auxiliary plate 35, so that the end of the scraper 32 is provided with a positioning sliding shaft block, so that the positioning sliding shaft block is clamped in the guide sliding groove, thereby limiting the relative deflection and sliding connection state between the mud scraping auxiliary plate 35 and the scraper 32, so that the mud scraping auxiliary plate 35 can be deflected around the connection position with the scraper 32, or directly slide along the guide sliding groove, thereby realizing the extension of the plate body, wherein the deflection and sliding are both changed under the action of gravity during downward rotation. The scraper 32 provided in the present application can push the sediments accumulated on the pool bottom to move in a directional manner during rotation with the rotating shaft 31, thereby pushing the sediments from the area outside the siphon range formed by the slag discharge pipe 4 to the siphon range centered on the inlet of the slag discharge pipe 4, so that the slag discharge pipe 4 can continuously and sufficiently transfer the sediments on the pool bottom. The sealing bearing 33 provided in the present application can limit the insertion position of the rotating shaft 31 while realizing the relative rotation of the rotating shaft 31, and can also avoid leakage of waste liquid from the insertion position of the rotating shaft 31 in the pool body. The mud scraping auxiliary plate 35 provided in the present application can increase the included angle between the plate body of the scraper 32 during downward movement of the scraper 32, thereby expanding the area of the entire plate body, so that the plate body can better push and transfer the sediments on the pool bottom. The relative deflection of the mud scraping auxiliary plate 35 can reduce the area of the entire scraper when in a non-mud scraping movement position, thereby reducing the disturbance of the plate body rotation to the waste liquid, avoiding the waste liquid being driven by the rotating plate body to be excited, ensuring the stability of the effectiveness of sedimentation, reducing the strength of the sediments being driven by the plate body when falling, so that the sediments can effectively settle and collect.In addition, the variable plate body area can more effectively scrape the deposits on the pool bottom, reduce the dead angle range between the two groups of rotating plate rollers 3 and the pool bottom surface, achieve a more effective scraping area, improve the scraping effect of the deposits, reduce the scraping gap area, and improve the fullness of the pool bottom cleaning.

[0036] Preferably, at least three groups of parallel deslagging pipes 4 are inserted from the side of the pre-cast base 2 to the top surface of the pre-cast base 2 in an upwardly inclined manner to communicate with the inner cavity of the pool shell 11.

The through inlet pipes 42 arranged on the same inclined main pipe 41 in the present application can be sequentially and alternately opened and closed under the opening and closing adjustment of the several electromagnetic valves controlled by the control program, thereby cleaning different areas at different time periods while maintaining the siphon strength, thereby ensuring the fullness and effect of continuous sediment transfer. The deslagging pipe 4 in the present application is connected with a plunger pump 5 and a filter pressing unit 6 corresponding thereto, thereby ensuring the siphon strength of the suction process and the effect of subsequent filter pressing. The inclined main pipe 41 in the present application is arranged in an inclined state, so that the sediment can be more effectively transferred, and the sediment accumulation is avoided.

[0037] Preferably, the plunger pump 5 in the present application is a conventional suction pump for sludge and other materials with obvious morphology.

[0038] Preferably, the filter pressing unit 6 is provided with a sludge pipeline 61 capable of discharging compressed and water-free deposits and a liquid discharge pipeline 62 capable of transferring the liquid separated by filter pressing. Preferably, the output end of the liquid discharge pipeline 62 is also connected with a pressurized liquid storage tank 63. Preferably, the pressurized liquid storage tank 63 is communicated with the backwashing pipe 7 through a delivery branch pipe 65 provided with a pressurized liquid pump 64. Specifically, the filter pressing unit 6 is a conventional filter press, which can compress and separate solid-liquid of the material containing water and other substances, improve the coagulation degree of the solid material, reduce the water content, facilitate the recovery and treatment of the material, and reduce the waste of water resources, thereby improving the water recycling capacity and efficiency.

[0039] Preferably, two mutually parallel backwashing pipes 7 are arranged on both sides of the discharge pipe 4 between the two groups of rotating plate rollers 3 to flush the deposits not pushed by the rotating plate rollers 3, so as to facilitate the rotating plate rollers 3 on both sides of the backwashing pipe 7 to push the deposits or the discharge pipe 4 to suck the deposits. Preferably, a plurality of water outlets are arranged on the pipe body of the backwashing pipe 7 at intervals, and a one-way electromagnetic valve allowing one-way output of pressurized liquid flow is further arranged in the pipe cavity.
