Description

Automatic discharge apparatus is disposed in city sludge process

Technical field

The invention belongs to a kind of corollary apparatus of city sludge process disposal facility, be specifically related to a kind of city sludge process and dispose automatic discharge apparatus.

Background technology

Along with the quickening of Urbanization Construction, the reinforcement of town dweller's growth in the living standard and national awareness of environment protection, various large and small type sewage work is extensively set up in cities and towns in all parts of the country, correspondingly, the sludgd deposition produced after sewage disposal is anxious according to increase, needs sludge quantity to be processed to get more and more, and the speed of process also needs to accelerate, otherwise, the major source of pollutant that the mud after sewage disposal will become a kind of difficulty and disposed again.City sludge is a kind of plastic mass (bacterium, fungi, protozoon, metazoan) be made up of zoogloea by deriving from after sewage work's process, viscosity is large, moisture dose rate high (water content is more than 80%), therefore be difficult to pass through mechanical dehydration.The method of existing lignin-sludge is landfill substantially, or burns.A large amount of burning waste of manpower, material resources, and landfill will cause second time to pollute, diffusion pathogenic agent, contaminated food chain.Whole nation urban wastewater treatment firm produces dewatered sludge and is about 1,800,000 t/ (wet mud 9,000,000 t/ of moisture 80%), because the stabilizing treatment facility of existing mud is less than 1/4, some places just directly discharge, and therefore become government department's insoluble significant problem.At present, the new case that existing partial sludge process is disposed occurs, level of automation and the processing efficiency of expection are higher, and thus the drawing mechanism of mud also needs correspondingly to reach automatization and efficient requirement.

Summary of the invention

The object of the present invention is to provide a kind of level of automation higher and automatic discharge apparatus can be disposed with opening with the city sludge process of closing.

The object of the invention is to realize by the following technical solutions: automatic discharge apparatus is disposed in this city sludge process, and it comprises feed box, and a side of feed box is provided with feeding mouth and is communicated with the discharge port of supporting specific resistance to filtration equipment; The feed box be positioned at below feeding mouth is provided with guide wheel, and guide wheel shaft is installed in the both ends of the surface of feed box, and one end that guide wheel shaft stretches out feed box is connected with reduction box with chain by two sprocket wheels, and reduction box is connected with buncher with belt by two belt pulleys; The bottom surface that described feed box is positioned at guide wheel turning direction is provided with discharge port, outside discharge port, movable plate is installed, tooth bar is fixed with below movable plate, rack and pinion engages, one end face of gear shaft is withstood by the dead axle that is installed on the end plate of feed box bottom surface by bearing, the other end of gear shaft is installed on relative feed box bottom surface end plate by bearing, and the gear shaft stretched out outside the end plate of feed box bottom surface is connected with reducing motor with chain by two sprocket wheels.

Concrete, in guide wheel shaft part, the sprocket wheel be connected with guide wheel shaft and reduction box is the hinge wheel of 10A21 tooth and the minor sprocket of 10A12 tooth respectively; Described reduction box is 1/3080 type reduction box, and the buncher be connected with this reduction box is 0.75KW buncher; The belt pulley be connected with described reduction box and buncher is the belt pulley of φ 200mm and the belt pulley of φ 80mm respectively.

Concrete, at gear shaft portion, the sprocket wheel be connected with gear shaft and reducing motor is the hinge wheel of 10A25 tooth and the minor sprocket of 10A12 tooth respectively; Described reducing motor is the buncher of 90W.

Concrete, the size of described movable plate is: 450mm*200mm.

Automatic discharge apparatus of the present invention, be provided with guide wheel in the below of feed box feeding mouth, guide wheel is driven by buncher and rotates, and automatically the dry pug entering feed box after process is pushed into the discharge outlet of feed box, eliminate the operation of artificial shovel material, alleviate the labour intensity of workman; Drive rack linear to walk by reducing motor, thus drive the opening and closing of movable plate, make discharge port timing discharging, the specific resistance to filtration equipment also preventing from outside air from entering into communicating with feed box.Therefore, automatic discharge apparatus of the present invention, achieves the object of automatical and efficient discharging, thus matches with the velocity efficiency of specific resistance to filtration equipment.

Embodiment

Below in conjunction with drawings and Examples, the present invention is described in further detail.

See Fig. 1, Fig. 2, the present embodiment comprises feed box 24, and the right flank of feed box 24 is provided with feeding mouth 42 and is communicated with by flange 43 with the aft end face of the thermal decomposition tube 2 of supporting specific resistance to filtration equipment; The feed box 24 be positioned at below feeding mouth 42 is provided with guide wheel 44, guide wheel shaft 45 is installed in the both ends of the surface of feed box 24, one end that guide wheel shaft 45 stretches out feed box 24 is connected with reduction box 48 with chain 47 by two sprocket wheels 46, and reduction box 48 is connected with buncher 51 with belt 50 by two belt pulleys 49; The bottom surface that feed box 24 is positioned at guide wheel 44 turning direction is provided with discharge port 52, movable plate 53 is installed outside discharge port 52, movable plate 53 is fixed with tooth bar 54 below, tooth bar 54 engages with gear 55, one end face of gear shaft 71 is withstood by the dead axle 57 that is installed on feed box bottom surface end plate 56 by bearing, the other end of gear shaft 71 is installed on relative feed box bottom surface end plate 58 by bearing, the gear shaft 71 stretched out outside feed box bottom surface end plate 58 is connected with sprocket wheel 61 with chain 60 by sprocket wheel 59, and sprocket wheel 61 is connected with reducing motor 62.

Working process of the present invention is: dewatered sludge enters in feed box 24 from the feeding mouth 42 of the flange 43 of thermal decomposition tube 2 aft end face, feed box 24 side, now start the buncher 51 of 0.75KW, passed to the belt pulley 49 of φ 200mm by belt 50 by the belt pulley 49 of φ 80mm, import 1/3080 type reduction box 48 into, the minor sprocket 46 of 10A12 tooth is passed to by the shaft of reduction box 48, the hinge wheel 46 of 10A21 tooth is passed to again by chain 47, thus drive guide wheel 44 to rotate clockwise, dewatered sludge is produced discharge port 52 place.Because do not allowed air to enter in thermal decomposition tube 2, if guide wheel 44 rotates, discharge port 52 long term open, air will can enter in thermal decomposition tube at any time, directly affects mud lytic effect, therefore must accomplish that discharge port 52 is with driveing with pass.The movable plate 53 of one piece of 450mm*200mm is housed bottom feed box 24, the reducing motor 62 of 90W starts, pass to the minor sprocket 61 of 10A12 tooth, the hinge wheel 59 of 10A25 tooth is driven by chain 60, pass through gear shaft 71 transmission again to tooth bar 54, because together with tooth bar 54 is fastened by bolts with movable plate 53, so tooth bar 54 drives movable plate 53 opening and closing.The straight line moving of tooth bar 54 and commutation are controlled by two travel switches, and realized movable plate 53 timed-shutoff opened, from the object reaching self-emptying by the time relay (adjustable 0-15 minute).
