Abstract

The invention provides a sludge cutting machine, which comprises a material cutting cylinder of which the lower part is provided with a material charging port and the upper part is provided with a material discharging port, a bearing seat and a motor which are arranged at the top end of the material cutting cylinder, a material cutting ring arranged on the middle part of the material cutting cylinder and a position adjustable cutter seat connected with the material cutting ring, wherein the motor is connected with a cutting blade by a driving shaft. The cutting machine is characterized in that: the cutting blade is a spiral blade, preferably an archimedes spiral blade which is also a double blade symmetrically arranged; and the position adjustable cutter seat is in bolting connection with the material cutting ring, and the material cutting ring is provided with an adjusting screw of which the end head is pressed against the cutter seat. Because the archimedes spiral line-shaped symmetrical blade is adopted in the sludge cutting machine, and the gap between the spiral blade and the fixed cutter seat can be adjusted, when the materials pass a via hole on the fixed cutter seat, double acting forces of chopping and cutting are generated on the material under the action of the cutting blade and the cutting edge of the via hole, so that the soft and hard materials can be crushed.

Description

A kind of sludge cutting machine

Technical field

The present invention relates to a kind of sludge cutting machine; especially relate to a kind of spiral-line sludge cutting machine; it is the preceding road treatment facility of sludge dewatering system; be installed in the suction line of mud spiral pump; blocks of solid thing in the mud (as wood, plastics, glass and stone etc.) is pulverized cutting, equipment in the protection sludge dewatering system.

Background technology

At present, common sludge cutting machine on the market, comprise by motor-driven blade and reaching and the adaptive chopping disk of blade, structure mainly is to adopt the straight knife sheet to come work with respect to the motion of chopping disk, material only has been subjected to the tangential component on the direction of blade operation, that is to say that material only is subjected to the reactive force that blade is cut, and the reactive force that does not cut can not effectively be pulverized in the mud comparatively pliable solid material like this.

Summary of the invention

The purpose of this invention is to provide a kind of sludge cutting machine, solve sludge cutting machine and can not effectively pulverize in the mud the comparatively problem of pliable solid material.Solid materials not only is subjected to the reactive force that blade is cut, and is subjected to the reactive force that blade cuts.

The technical solution adopted for the present invention to solve the technical problems is: a kind of sludge cutting machine, comprise that the bottom has opening for feed, top that the blank tube of discharge port is arranged, be arranged on vertical bearing support of blank tube and motor, be arranged on the blank ring at blank tube middle part and connect adjustable position tool rest on it; Described motor is connected with blade by drive shaft; It is characterized in that: described blade is the spiral-line blade.

For better cutting, described blade is the spiral of Archimedes blade.Described blade is symmetrically arranged double blade.

Described adjustable position tool rest is that tool rest connects with the blank collar bolt, and on the blank ring set screw is set, and the set screw termination heads on tool rest.

Positively effect of the present invention is, because sludge cutting machine has adopted the symmetrical blade of spiral of Archimedes shape, and adopt and to regulate screw blade and the fixing gap between the tool rest, when material during by the via hole on the fixing tool rest, material is under the effect of blade and via hole cutting edge, the double reaction plus that generation is cut and cut can make hard and the softish material is all pulverized.

Major advantage of the present invention is: 1, compact construction, volume is little, floor space is few; 2, simple to operate, easy to maintenance; 3, can non-stop run, treatment capacity is big; 4, energy consumption is low, the running maintenance expense is low, safe and reliable; 5, the kind of blank is wide, and equipment uses extensively.

Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.

Description of drawings

Fig. 1 is the sludge cutting machine structure cutaway view.

Fig. 2 is the A-A sectional view of Fig. 1.

Among the figure: 1. motor, 2. drive shaft, 3. bearing support, 4. sealing-ring, 5. blade, 6. tool rest, 7. blank tube, 8. base, 9. opening for feed, 10. discharge port, 11. via holes, 12. materials, 13. bolts, 14. screws, 15. blank rings.

Embodiment

As shown in Figure 1, 2, a kind of sludge cutting machine, comprise that the bottom has opening for feed 9, top that the blank tube 7 of discharge port 10 is arranged, be arranged on blank tube 7 vertical bearing support 3 and motors 2, be arranged on the blank ring 15 at blank tube 7 middle parts and connect adjustable position tool rest 6 on it; Described motor 1 is connected with blade 5 by drive shaft 2.Described blade 5 is spiral-line blades.For better cutting effect, spiral of Archimedes blade and be symmetrically arranged double blade preferably.

Described adjustable position tool rest is that tool rest 6 connects by bolt 13 with blank ring 15, and on blank ring 15 set screw 14 is set, and set screw 14 terminations head on tool rest 6.On the blank ring, be evenly equipped with 3 or 4 in order to connect with the even described set screw of adjustment.

During concrete the making, each part type of attachment of sludge cutting machine is: a base 8 can also be set be fixed on the basis, ground by 4-φ 20 wall screw, blank tube 7 and base 8 are connected by bolt.Motor 1 is installed on the upper surface that is welded on the blank tube 7 bearing support 3.Screw blade 5 links to each other with motor by drive shaft 2, and drive shaft is not axially having mobile space, and blade can be fixed on the drive shaft by gland and key mode, has guaranteed the rigidity of total system.Also be provided with sealing-ring 4 between drive shaft 2 and the bearing support 3.Tool rest 6 is connected with blank ring 15 and blank tube 7 by bolt, and a plurality of via holes 11 (as six) of band keen edge are arranged on the tool rest 6, and the plane contacts with screw blade 5 lower planes on the tool rest 6, and leaves the adjustable cutting gap less than 0.1mm.

Mud material 12 enters blank tube 7 bottoms by opening for feed 9, along with the increase that enters blank tube sludge volume, mud can upwards flow from six via holes 11 of fixing tool rest, this moment bigger in the mud will be as solid materialss such as wood, plastics, glass and stones at moving screw blade 5 and fixedly under the interaction of six via hole keen edge of tool rest, be subjected to insert tangential and radial cutting force and pulverizing rapidly, then overflow by discharge port, enter sludge pump, enter dewatering system again.In the reality, because the contained solid matter kind of mud is comparatively various, for different mud, in order to reach best cutting effect, adjusting screw blade and the fixedly gap between the tool rest at work.
