The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
Like Fig. 1, a kind of defecator comprises mortar storage tank 1 and the support 2 that is arranged on mortar storage tank 1 bottom; Said mortar storage tank 1 is the storehouse cylindrical structure, and its inside is provided with torque transmitting shaft 5, and torque transmitting shaft 5 bottoms are connected with changes rake 6; Mortar storage tank 1 bottom is provided with center bucket 16; Mortar storage tank 1 inside is provided with tube settler 3 and surface scum thing feeder 4, and mortar storage tank 1 sidepiece is provided with and mixes reaction zone 8, mixes and is connected with pipe-line mixer 9 on the reaction zone 8.
Said pipe-line mixer 9 bottoms are provided with dosing mouth 10.
Said mortar storage tank 1 top is provided with exhaust outlet 12, instrumentation tap 13 and manhole 14.
Said mortar storage tank 1 sidepiece is provided with sample tap 11 and delivery port 15.
Operation principle of the present invention and process are:
Defecator is by mixed zone, reaction zone, drainage district, decanting zone, middle part, top settling section, and bottom mud-sinking area, bottom collection bucket and clarified solution are collected ditch and formed.At first, sewage and flocculant deliver into the mixed zone through pump.Agitator is housed in the mixed zone, sewage and flocculant are fully mixed in this zone, and guarantee that all solids are in suspended state, can not stop up the import of sewage and flocculant.Sewage fully mixes the back with flocculant and gets into reaction zone, and the effect of reaction zone is to suitable reaction time of flocculant, forms the alumen ustum that is beneficial to deposition.After forming alumen ustum, sewage gets into the drainage district.The effect in drainage district is when guaranteeing that the outlet of sewage and clarified solution is not short-circuited; Sewage hybrid reaction after good causes the decanting zone, middle part; Sewage stopped 2 hours in this zone; Particle diameter is bigger therebetween, and the solid suspension that quality is bigger can be because the gravity effect precipitates, and this zone can guarantee 100% removal to bigger particle.The small suspended particle that part fails to precipitate in the decanting zone, middle part is along with sewage gets into the top settling section.The top settling section is the main settling zone of small solid particle, and this district is provided with inclined plate settler,
The mortar storage tank is simple silo type structure, and by decanting zone, middle part, top settling section, the bottom mud-sinking area is formed.The volume of decanting zone, middle part and top settling section is big, and residence time of material reaches 24 hours, under the effect of flocculant and antifoaming agent, leaves standstill for a long time, makes small solid particle and foam obtain removing comparatively completely.Being provided with in the mud-sinking area of bottom changes rake, and the mud that precipitates is harrowed to the center bucket, concentrates the back to discharge.
The housing wall thickness is 12mm, base plate thickness 14mm, butterfly cover plate 8mm.
Defecator is located at a side (symmetrical with the clarified solution overfall) by mixed zone, reaction zone, drainage district.The drainage district is provided with anti-short circuit distribution baffle to the natural subsidence district.The hybrid reaction district is arranged on the apparatus body outside, and defecator PAM dosing mixes the district to defecator, and the PAC dosing adds stirring area after through the vertical pipeline mixer mixing, and the vertical pipeline blender guarantees that enough time of staying are arranged, and avoids two kinds of medicaments to react.
Should count requirement in strict accordance with the mouth of pipe of tables of data and shell sketch map during the designing apparatus mouth of pipe, mouth of pipe size design back well submits to the buyer and the examination of buyer designing institute to confirm.
Will there be top seal the cell body top; Top cover adopts overlap welding, and to guarantee having sufficient intensity to support its top facility and own wt, top cover is except the manhole that requires; When also cover plate being set and being convenient in accident condition and operating mode in convenient position of opening; Cleaning primary water top floating material when cover plate closing, should have good sealing property.On the top cover steam vent to be set separately, guide to home emptying by section of a pipe.
The housing sprayed surface should be concordant, and face of weld should be smooth, and welding slag, overlap and burr must not be arranged.Corners such as flange adapter inner edge must reconditioning become rounding off, and radius of corner is at least 3～5mm.
Machined surface and non-machined surface linear dimension are not annotated tolerance person, carry out by m level of stipulating among the GB/T1804 and c level respectively.
Changeing the rake support directly supports on the ground.Support changes the dynamic load that also need bear 180kg/m the rake load except that bearing, and the brace summer amount of deflection should be less than 1/360 of span under above-mentioned loading condition.
Change the rake startup and should satisfy unloaded and fully loaded two kinds of operating modes.The fully loaded startup of changeing rake requires: when bad working environments occurring, when defecator has half groove to contain the mortar of mud 40-50% with the mortar-trough bottom, change rake in the bottommost mortar under situation about not promoting, can start, and safety and steady moves.
Defecator changes rake, the mortar storage tank changes rake and adopts bridge-type to support the top-feed type.Drive unit is supported on the crane span structure and drives two steel construction rake arms through torque transmitting shaft and rotates.Power transmission shaft should be designed to bear the driving torque of twice and each member does not all transship with the rake arm.
Change rake drive motors power 3KW, rotating speed 0.03-0.05r/min, promote power of motor 1.5KW.
The axle that the commentaries on classics rake contacts with medium, rake arm and cleaning shoe employing carbon steel line with rubber (serve as a contrast butyl rubber, thickness 5mm, and must not be less than two-layer), all the other material selection 317L.
Change rake: form by power transmission shaft and rake arm, by bridge-type steel frame support across storage tank.Drive unit is furnished with promptly manually changes the rake lift crank, in order under power failure or accident condition, using.
The rake arm is collected the mud awl bottom outlet that is located at the bottom land center with the mud of bottom aggradation from whole bottom land.
Two mud collection rake arms (constituting with rod member) that cleaning shoe is housed are installed on the torque transmitting shaft and rotate with axle, and steel blade is securely fixed on the rake arm.Adjustable for height carbon steel scraper plate also should be housed on the scraper, and the bottom of scraper should be stretched out in the bottom of scraper plate.Should there be certain safe distance the bottom surface of scraper plate with trough floor.
Embodiment recited above describes preferred implementation of the present invention; Be not that design of the present invention and scope are limited; Do not breaking away under the design concept prerequisite of the present invention; Common engineers and technicians make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention, and the technology contents that the present invention asks for protection all is documented in claims.
