Abstract

The utility model relates to an automatic cleaning device for the water catch groove wall of a water curtain type radial sedimentation tank used for sewage treatment, belonging to environmental protection equipment. The automatic cleaning device comprises a sedimentation tank (1), a triangle weir plate (2), a water catch groove (5), a mud scraper (7), a mud scraper running gear (11) and a mud scraping plate (10); an open U-shaped drencher pipe (4) is arranged in the water catch groove (5), the upper end of the central pipe of the drencher pipe (4) is connected with a valve and a water pump, the central pipe is communicated with the bottom part and both sides of the U-shaped pipe, doublebank spiracles (4-1) are alternatively arranged on both sides of the center of the external pipe wall of the U-shaped drencher pipe (4); a reverse T-shaped supporting and hanging frame (3) is arranged below a cross branch pipe of the central pipe, the upper end of the supporting and hanging frame (3) is connected with the mud scrapper (7), the rotation of the mud scrapper (7) can drive the operation of the open U-shaped drencher pipe (4). The automatic cleaning device has the advantages of simple structure, consumables free and maintenance free, operation cost conservation and high automatic level.

Description

The water curtain style radial-flow sedimentation tank cell wall automatic flushing device that catchments

Technical field

The utility model belongs to environmental protection equipment, particularly a kind of water curtain style radial-flow sedimentation tank of sewage disposal cell wall automatic flushing device that catchments.

Background technology

Circular radial-flow sedimentation tank is one of general structures of sewage disposal, the water inlet of many employings center, center spoil disposal peripheral effluent mode, supporting with it peripheral drive formula mud scraper is absolutely necessary and scrapes soil discharging facility, former water enters from central island, flow to periphery in spoke stream mode, by the mud scraper rotating blade being deposited to the mud-removing bucket that mud at the bottom of the pond is pooled to the center.The heavy gradually mud that forms at the bottom of the pond of sediment in this process, by the rotation of mud scraper, scraper plate collects in middle mud-removing bucket to the mud that is deposited at the bottom of the pond, by liquid level difference mud is discharged outside the pond.The current direction periphery of post precipitation is gone into U type water leg through the triangular-notch weir plate current simultaneously, and like this, water leg and the easy fouling of triangle weir plate generate various algae, and in a single day algae comes off will influence water quality, therefore will clean.Clean water leg at present and adopt the commentaries on classics brush to clean more, complex structure, often bottom or the periphery to water leg cleans not thoroughly, changes the brush bristle in addition and also very easily weares and teares, and can not guarantee that bristle fully contacts with the cell wall that catchments, and needs periodic replacement, increases operating cost.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of water curtain style radial-flow sedimentation tank simple in structure, that cleaning performance is good cell wall automatic flushing device that catchments is provided.

The technical scheme that the utility model technical solution problem adopts is: the water curtain style radial-flow sedimentation tank cell wall automatic flushing device that catchments is made up of sedimentation basin, triangle weir plate, water leg, mud scraper, mud scraper running gear, cleaning shoe, be characterized in water leg, adorning a uncovered U-shaped sparge pipe, the central tube upper end of sparge pipe connects valve, water pump, central tube and U-shaped pipe bottom, both sides three-dimensional are connected, and the both sides, center are staggered on U-shaped sparge pipe outer tube wall establishes double hole for water spraying; Adorn one and fall T-shaped suspension and support below the horizontal arm of central tube, the suspension and support upper end is connected with mud scraper, drives uncovered U-shaped sparge pipe rotating operation when mud scraper rotates.

The beneficial effects of the utility model are: the water curtain style radial-flow sedimentation tank catchments, and double staggered hole for water spraying can thoroughly wash the triangle weir plate to the cell wall automatic flushing device and catchment cell wall and bottom because employing sparge pipe outer wall is established, and avoids the formation of dirt and algae.This apparatus structure is simple, do not need any running stores, need not safeguard, save operating cost, owing to clean up thoroughly, can move once in 2～3 days, each run one circle gets final product, and saves electric energy with rotary-brush type wiper mechanism ratio, cleaning strength can be by the valve adjustment, easy to use, with PLC multiple devices are realized centralized Control, automatization level is higher.

Description of drawings

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 shows that the water curtain style radial-flow sedimentation tank cell wall cleaning device structure master that catchments looks cutaway view.

The uncovered U-shaped sparge pipe of the cleaning device of Fig. 2 diagrammatic sketch 1 structure chart.

The P of Fig. 3 diagrammatic sketch 2 is to view.

Among the figure, the 1-sedimentation basin; 2-triangle weir plate; The 3-suspension and support; The uncovered U-shaped sparge pipe of 4-; The 4-1-hole for water spraying; The 5-water leg; The 6-truss that catchments; The 7-mud scraper; The 8-central island; 8-1-central island bearing revolving part; 9-cleaning shoe frame; The 10-cleaning shoe; 11-mud scraper running gear;

The specific embodiment

Embodiment, with reference to accompanying drawing 1, the water curtain style radial-flow sedimentation tank cell wall automatic flushing device that catchments, the bottom of circular settling tank 1 is a V-shaped groove central row bucket; In V-shaped groove, fix a central island 8, fix a bearing revolving part 8-1 above the central island 8, mud scraper 7 is equipped with in activity on bearing revolving part 8-1, mud scraper 7 other ends are fixed on the running gear 11 above the outer of sedimentation basin 1, fixing cleaning shoe frame 9 below mud scraper 7, cleaning shoe frame 9 lower ends are cleaning shoe 10 fixedly.Mud scraper 7 rotates on the outer of sedimentation basin 1 under running gear 11 drives, and drives cleaning shoe 10 rotations, the mud of 1 bottom, scavenger precipitation pond.In sedimentation basin 1,, on the truss 6 that catchments, water leg 5 is housed fixedly, fixed triangle weir plate 2 on the outer, water leg 5 upper end along fixing several bar shapeds truss 6 that catchments on the wall.Uncovered U-shaped sparge pipe 4 is housed in water leg 5, and uncovered U-shaped sparge pipe 4 usefulness are fallen T-shaped suspension and support 3 and are lifted in the water leg 5 of mud scraper below.Uncovered U-shaped sparge pipe 4 is 10cm with water leg 5 spacings.The central tube upper end of uncovered U-shaped sparge pipe 4 connects valve, water pump.With reference to accompanying drawing 2,3, central tube is communicated with the side and the following three-dimensional of U-shaped pipe, submits mistake at the outside of uncovered U-shaped pipe 4 tube wall and establishes double hole for water spraying 4-1.The water of ejection forms water curtain like this, can thoroughly clean cell wall, bottom and the triangle weir plate 2 of water leg 5, can avoid the formation of dirt and algae, and its control adopts PLC that multiple devices are realized centralized Control.
