Abstract

The utility model relates to a pulverization type grid trash-cleaning machine, which belongs to the field of trash-cleaning machinery for water treatment. A driving gear is installed on a driving shaft, and a driven gear is installed on a driven shaft. The driving gear and the driven gear are mutually meshed and in the state of opposite motion, and multi-tooth reamers are respectively installed on the driving shaft and the driven shaft in a staggered way; the driving gear transmits the motion to a drum grid gear coaxial with a water-flowing grid cylinder through a transition gear. The trash-cleaning machine is characterized in that a thin-tooth reamer and a thick-tooth reamer are installed on the driving shaft and the driven shaft. The trash-cleaning machine has the advantages of simple structure, good compatibility, wide applicability and high automation degree.

Description

The crush type grid trash rake

Technical field

The utility model relates to the water treatment mechanical field of removing contamination, and specifically belongs to the crush type grid trash rake.

Background technology

The crush type grid trash rake is applicable in the pretreatment process of drainage pumping station, municipal sewage plant and industrial enterprise's sewage disposal, be with the solid-state foreign material of large volume in the water inlet, for example timber, glass wine bottle, plastics, cotton, rubber item, iron nail, finger stone etc., cutting and grinding become the small-particle of 5-12mm, flow to subsequent disposal with sewage, removed obstacle for the subsequent disposal processing apparatus, guaranteed that effectively follow-up equipment is unimpeded smoothly.

Existing crush type grid trash rake product was provided with the multiple tooth reamer of boom tube and two move toward one another, sheared by two multiple tooth reamer move toward one another and pulverized the solid-state foreign material of large volume.Two the multiple tooth reamer number of teeth is equal, profile of tooth is consistent.If two multiple tooth reamers all are the bastard reamers, then can pulverize the solid-state foreign material of comparatively large vol, bigger but shortcoming is a small particle diameters after pulverizing, easily block or damage the subsequent disposal processing apparatus; If all be the serration reamer, then can obtain particle after the less pulverizing, but the front portion is difficult for being winched into the solid-state foreign material of large volume, easily blocks, suitability is also bad.When taking place to block, because reamer is stuck, electric motor is also turning round simultaneously, therefore as easy as rolling off a log damage motor and equipment.And need the people for stopping motor, and artificial the removing blocked dirt.

The utility model content

Can not take into account simultaneously at crush type grid trash rake in the prior art and to be winched into the dirt size and to cut with scissors out particle size, simultaneous faults is handled problems such as intellectuality inadequately, what provide is a kind of simple in structure, compatible good, the crush type grid trash rake that suitability is wide and level of automation is high.

The technical scheme that the utility model adopted is as follows:

A kind of crush type grid trash rake, driving toothed gear is installed on the main drive shaft, follower gear is installed on the driven shaft, driving toothed gear and follower gear intermesh, be the move toward one another state, interlocking respectively on main drive shaft and the driven shaft is equipped with multiple tooth reamer, and driving toothed gear is by transition gear and cross the co-axial bulging grid toothing of boom tube; The staggered respectively multiple tooth reamer of installing is serration reamer and bastard reamer on described main drive shaft and the driven shaft.

The number of teeth of described bastard reamer and serration reamer is respectively odd number, and the profile of tooth of bastard reamer is the straight-tooth profile of tooth, and the profile of tooth of serration reamer is the sawtooth profile of tooth.

The utility model adopts the cooperation of serration reamer and bastard reamer, and solid-state foreign material are pulverized, and the solid-state foreign material compatibility for the treatment of pulverizing is good, and suitability is wide.

Description of drawings

Fig. 1 is the front view of crush type grid trash rake internal structure;

Fig. 2 is a sectional view of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, specify constitutional features of the present utility model and principle of work.

As shown in Figure 1: the crush type grid trash rake consists of, and on its main drive shaft 4 driving toothed gear 5 is installed, and follower gear 7 is installed on the driven shaft 6.Driving toothed gear 5 and follower gear 7 intermesh, and are the move toward one another state.Serration reamer 3 is installed on the hexagonal axis of main drive shaft 4, bastard reamer 2 is installed on the hexagonal axis of driven shaft 6, serration reamer 3 and bastard reamer 2 staggered installations, its endoporus is the hexagon ring that cooperates with hexagonal axis.Driving toothed gear 5 transmitted motion to boom tube 1 co-axial bulging grid gear 9 by transition gear 8, was kinestate in the same way with main drive shaft 6.Cross between boom tube 1 and the serration reamer 3 and have the gap, gap width was not more than the width of the water flowing grid of boom tube 1.

As shown in Figure 2: sewage disposal water-in or intakes of pumping station pass through the solid-state foreign material of large volume that boom tube 1 blocks in the water, are rotated counterclockwise by mistake boom tube 1 foreign material are driven between serration reamer 3 and the bastard reamer 2.4 rotations of motor drives main drive shaft, main drive shaft 4 transferring power are given driving toothed gear 5, driving toothed gear 5 is given follower gear 7 with transmission ofenergy again, the energy of two gears is delivered to serration reamer 3 and bastard reamer 2 by hexagonal axis, two broken foreign material of reamer move toward one another cutting hinge, realize pulverizing, the grid slag after the pulverizing is taken away with current.Owing to adopted serration reamer 3 and bastard reamer 2 to match, not only can be winched into the dirt impurity of large-size, and can cut with scissors out the dirt particle of reduced size simultaneously, improved the suitability of product greatly.In actual the use, the number of teeth of serration reamer 3 is 11 teeth, and profile of tooth is a zig-zag.The number of teeth of bastard reamer 2 is 5 teeth, and profile of tooth is a straight-tooth shape.

In crushing process, be winched into solid-state foreign material of large volume or hard solid-state foreign material, thereby easily take place two stuck obstructions of reamer.At this moment, pilot circuit detects main drive shaft rotation overload, and pilot circuit is auto-reverse main shaft 4, thereby obstacle is discharged, and is delivered to the cutting and grinding district again and pulverizes by crossing boom tube 1.If occur unusual two to three times in a short time repeatedly, pilot circuit needs artificial removing obstacles with auto stop and warning, makes whole crushing process realize automatization substantially.Pilot circuit wherein adopts conventional electronic control technology.

The utility model is simple in structure, and compatible good, applicability is wide and automaticity is high. Not only can Be applied in the crush type grid dirt removing machine, and can be widely used in the industrial equipment of similar demand.
