Description

Sludge Crusher for waterway with improved crushing structure

The present invention relates to a contaminant crusher, and more particularly, various sludges (condensate) flowing in the state contained in sewage or wastewater are pulverized and discharged evenly in the form of small grains, thereby preventing clogging of the channel by various foreign substances. The present invention relates to a complex crusher with improved torsional crushing structure.

In general, a crusher is a kind of waste treatment equipment installed in a discharge channel such as a sewage treatment plant (such as sewage and manure treatment facilities of a domestic or factory). Such a crusher for water can be collected from simple food waste, vinyl, toilet paper, etc. Various kinds of contaminants that cause clogging of waterways, such as cloth, plastic, beverage cans, wood, rubber, and other various types of foreign matter, are pulverized to facilitate the discharge of sewage.

Thus, briefly look at the configuration of the conventional channel-type contaminant crusher that is installed, used for the above uses;

This, as shown in Figure 1, as a configuration, the inner surface of the housing 30 having the inlet 10 and the discharge port 20 integrally provided with a plurality of grinding blades 40, the grinding shaft 50 is installed , And configured to further connect the power motor 50 for transmitting rotational power to the grinding shaft 50.

However, as described above, the conventional contaminant crusher is merely a configuration in which a plurality of grinding blades are simply stacked on a grinding shaft that is installed upright in a single structure. Thus, by the grinding shaft having a single configuration, As the foreign matter could not be crushed evenly, the grinding efficiency was inevitably deteriorated. In particular, the crushed foreign material was caught between a plurality of laminated blades and the grinding blades, which hindered the flow of sewage. This disruption of sewage flow has led to significant structural closure problems, such as contaminants accumulating in the crushed housing and causing blockages.

On the other hand, in recent years, as a way to solve some of the problems of the conventional contaminant crusher, a technique in which the crushing shaft is installed and applied in a pair of configurations in which the crushing shaft is joined to the left and right, for example, the "torsion crushing" filed by the present inventors "Crusher crusher having blade installation structure" (Patent Application No. 2010-19894) has been invented.

However, the complex crusher as the source technology, a plurality of grinding blades are laminated and bonded on the grinding shaft in a multi-stage torsion structure, and as described above, the grinding shafts are laminated and bonded in a pair of configurations in which left and right symmetry is performed. Although the crushing efficiency of the crusher as a source technology is such that the two crushing shafts are symmetrical to the left and right, the pulverization crusher is intended to be applied to a large capacity pipeline type water treatment facility. In this case, the crushing cross-sectional area is relatively small, and there is a considerable difficulty in installation and use. In addition, in the pulverization operation, as the pulverization axis simply forms a pair of symmetrical structures, vinyl to synthetic resins If foreign matters such as these are caught, they will not be effectively crushed and discharged, and they will remain stuck between the grinding blades. It was to give a problem that causes the phenomenon.

On the other hand, in the alternative, the above-described junk crusher as a source technology, when the inflow of the trickle rapidly increases due to the impact of flooding, or when a foreign substance flows into a hard foreign material such as metal, a significant overload occurs. Preventive measures are not provided at all, which not only imposes a considerable burden on the equipment and provides a cause of the failure, but also causes a series of maintenance costs, such as maintenance and maintenance, unnecessarily excessively. The problems of considerable structural deficiencies and economic deterioration, such as wasted, were to be present.

Therefore, the present invention was devised to solve the general problems of the conventional contaminant crusher;

An object of the present invention is to install the first driven grinding shaft and the second driven grinding shaft in a three-axis structure in which a mutual grinding blade is engaged with each other on the left and right sides of the driving grinding shaft. The structure in which the first and second driven grinding shafts are disposed forward in front of the driving grinding shaft, for example, in the form of a triangular sphere arrangement, further forms a "V" shaped contaminant guiding groove so that the complicated object is broken. In addition, the three-axis configuration allows the shredding cross-sectional area to be relatively increased, and the crushing structure can be easily applied and installed in a large-scale pipeline type water treatment facility. An improved mess crusher is provided.

In addition, another object of the present invention, by the drive conversion sensor and the setting timer provided in the drive control unit, the operation relationship of the drive grinding shaft to the forward and reverse conversion in a repetitive, continuous form over a set time range, the vinyl to synthetic resin It is possible to effectively grind and discharge the foreign substances such as tough substances without residual phenomena, and also, if excessive impurities in the contaminants or the inflow of hard foreign substances such as metals, etc. occur in the device, this is caused by an overload prevention sensor. The present invention provides a fine crusher which has an improved grinding structure to stop the operation of the drive grinding shaft or to change the direction of operation, thereby preventing the damage and failure of the device.

On the other hand, a further object of the present invention is to provide a grinding structure in which the installation position of the drive grinding shaft is arranged forward and backward as needed to variably adjust the depth of engagement of the grinding blade, thereby greatly increasing the grinding efficiency. An improved mess crusher is provided.

Thus, in order to achieve the above object, as a specific means of the fine crusher to improve the grinding structure according to the present invention;

The first driven grinding shaft and the second driven grinding shaft are further provided in a symmetrical structure on both the left and right sides of the driving grinding shafts, which are installed on the inner side of the housing, to form a three-axis configuration. In the axial configuration, the first driven grinding shaft and the second driven grinding shaft are arranged in a predetermined length forward direction in front of the driving grinding shaft to further form a "V" shaped concave guide groove in the inner center of the housing. .

Therefore, the compactor crusher having the improved grinding structure according to the present invention advances and arranges the first driven grinding shaft and the second driven grinding shaft in a three-axis coupling structure at the front left and right of the driving grinding shaft. "By forming the triangular arrangement structure in which the shaped conduit guide grooves are formed, the formed conduit guide grooves allow the flowed contaminants to smoothly flow into the crushing site, and also, such as vinyl, cloth, synthetic resin, etc. When foreign matters of the nature are wound on the grinding shaft or remain in the form of being caught on the grinding blade, it is to be easily cut and crushed in the form of two-sided right and left by the three-axis configuration. The crushing cross-sectional area is relatively increased by the soccer property, so that the crusher can be easily applied and installed in a large-capacity pipeline type water treatment facility.

Alternatively, the complex crusher according to the present invention improves the crushing structure, the operation relationship of the drive crushing shaft by the drive conversion sensor and the setting timer provided in the drive control unit according to the set time range, the forward and reverse in a repeating, continuous form By converting, the phenomena of tough substances such as vinyl or synthetic resin, etc. are periodically eliminated or residual phenomenon, and also, if excessive occurrence of contaminants or inflow of hard foreign substances, such as metal, if the device is excessive, This is to stop the operation or change the direction of operation by the detection by the overload prevention sensor, so that the cause of the damage and failure of the equipment is prevented at the source, and the installation position of the drive grinding shaft is also, if necessary, Arranged backwards to make it possible to variably adjust the depth of engagement of the grinding blades, making the grinding efficiency extremely Increasingly, this provides a very useful expected effect.
