Description

Cutting device of input-sack for a shaftless spiral screw type drier}

The present invention is a bag-type feeder for a sludge drying device for drying sludge, a non-spindle spiral screw type drying device applied to waste incineration facilities and food processing facilities, etc. The present invention relates to an improvement of a cutting device.

As a kind of drying equipment, oil and inorganic sludges of humid substances such as sewage sludge, satin wastewater sludge, and sluice sludge generated in various industrial sites such as food factories, textile and paper mills, sewage treatment plants, and livestock farms As a type of sludge drying apparatus that dehydrates or dries below a certain moisture content to be suitable for incineration, recycling, or landfilling, there is a non-spindle spiral screw previously filed in Korea Utility Model Application No. 2001-33674 by one applicant of the present invention. There is a sludge drying device using.

The sludge drying apparatus using the spindle-free spiral screw of the above-mentioned application uses a spindle-free spiral screw as a conveying means of the sludge, so that the sludge has a higher water content and a higher viscosity than the configuration using the spindle-type screw. It is designed to reduce the phenomena attached to the spindle screw and to achieve the effect of increasing the sludge conveying speed in the drying chamber of the same standard, smoothing the sludge stirring during conveying, reducing the driving force and remarkably improving the sludge drying efficiency. .

In addition, the sludge drying apparatus using the spindle-free spiral screw of the above application, it is easy to configure a high-speed drying device and a high capacity drying device while miniaturizing the configuration of the drying device, has the advantage of easy maintenance of the entire drying device, Ultimately, the installation requirements for sludge dryers can be universalized to facilitate the installation of sludge dryers in sludge generators or sludge handlers, furthermore, to ensure that the water content of the sludges can be used as incineration fuel or meet the landfill standards. It can be very easily dried to a level, thereby preventing the occurrence of pollution and pollution due to the high water content of the sludge landfill, and provides a sludge drying apparatus having advantages that can actively induce the recycling of sludge It is devised to do.

According to the above characteristics, the sludge drying apparatus using the non-spindle spiral screw of the pre-application is used as a pre-treatment facility as a pretreatment facility in various waste incineration facilities or food processing facilities, which require a dehydration and drying process, although the characteristics of the treated materials are different. The situation is being used.

As described above, when the sludge drying device using the no-spin spiral spiral screw of the above-mentioned application is used as a drying device in various waste incineration facilities or food processing facilities that require dehydration and drying processes, the characteristics of the treated product are different from that of the sludge, Problems occur with drying and dehydration effects.

Most of the wastes and food wastes that are processed in incineration facilities or food processing facilities are enclosed in paper bags, plastic bags or synthetic resin bags and are collected as bags. There is a characteristic to become.

Therefore, if such a bag-filled processed material is directly introduced into the inlet of the dedicated drying device as it is, the bag or bag can be easily transported to the discharge port by a spindleless spiral screw in the drying chamber. There was a problem that the drying, dehydration effect on the contents of the envelope-encapsulated treatment did not burst.

In order to solve this problem, conventionally, in the case of a bag-encapsulated processed material, it is inconvenient to insert a portion of the bag or cutting edge by artificially cutting the envelope or the stem with a knife or a saw blade before putting it into the inlet of the drying apparatus.

In addition, the sludge drying apparatus using the spindle-free spiral screw of the above application is dried and stirred by cement, flour, chemicals, feed, fertilizer of powdery logistics by the characteristics of its configuration and some effects It is also used as an apparatus for conveying (hereinafter referred to as a powder-phase stirring conveying apparatus).

Even when the above-mentioned spindleless spiral screw type drying device is used as a powdered material stirring conveying device, the powdered materials that are dried and agitated conveyed are mostly packaged in a paper or synthetic resin bag or bag, so that the powdered material is dried and stirred. In order to maintain the normality, it is inconvenient to cut and insert several parts of the bag or bag around the bag or bag by artificially using a knife or saw blade, or through a separate bag shredding device before being put into the inlet of the powdered agitating feeder. This was there.

In the above-mentioned application of the spindleless spiral screw type sludge drying apparatus of the pre-application to an incineration facility, a food processing facility, or a powder-stirring conveying device, the knife encapsulated processed materials (feeds) are cut before the feeding process into the drying device. When an artificial bag cutting process by a saw blade or the like or a separate bag shredding device is interposed, a considerable labor cost is required as well as an increase in equipment cost and a slow operation time.

In order to solve the above problems, there is a 'bag envelope cutting device using a no-axis spiral screw' of the domestic utility model registration No. 20-0294898 provided by one of the inventors of the present invention (hereinafter referred to as a line design).

The features of the above-mentioned line design, as the additional configuration while using the configuration of the spindle-free spiral screw type sludge drying apparatus disclosed in the prior application,

 In the inner circumferential end of the screwless spiral screw (inside thick member of the screw), a simple old envelope encapsulated insert cutting means such as a disk blade, a semi-circle blade, a toothed blade, etc., is provided. It is intended to be used as a drying device for bag-filled inputs, such as powder conveying device.

 According to the configuration of the above-described design, the envelope encapsulated input is introduced into the chamber inlet of the drying apparatus, and is spirally and axially oriented forward with respect to the rotation axis by a spindleless spiral screw that rotates in a non-axial direction. In the process of drying the bag-loaded inputs by the drying means installed in the chamber while gradually pushing the bag-loaded inputs toward the discharge side by the formed screw plate surface, the disc-shaped blades or toothed blades provided on the inner circumferential end of the spindleless spiral screw rotate together with the screws. By cutting, cutting or breaking the circumference of the envelope encapsulated inputs in several parts, the sludge and various wastes or powders, which are the contents of the envelope encapsulated inputs, are easily exposed to dryness or agitation, thereby increasing the efficiency of dehydration and drying. It can also increase the stirring action There.

Therefore, according to the pre-design, it is possible to dig and dry the envelope encapsulated inputs very easily, smoothly and quickly, without a separate bag cutting operation before the chamber inlet and without a separate bag shredding device. It is possible to obtain the effect of reducing the labor cost and equipment cost by drying the enclosed input and stirring transfer treatment.

However, according to the configuration and action of the above design, the cutting or breaking action of the envelope encapsulated inputs in the chamber occurs very limitedly or locally due to the transfer action of the drying chamber and the spindleless spiral screw. The problem occurs that does not occur at all, and it is shown that it is not theoretically and practically unsuitable to achieve smooth and satisfactory increase of the desired drying effect and agitation efficiency.

Structural features of the chamber of the spindleless spiral screw type sludge drying apparatus and the spindleless spiral screw disclosed in the above-described design, while the shape of the screw is formed spirally by the screw plate surface of a certain area (width), the central shaft portion has no shaft It consists of a spindle-free spiral screw with a cavity having a certain diameter formed by an inner thickness member of the screw, and the screw of the screw and several supporting pieces installed at the bottom of the chamber inside the horizontal cylindrical chamber. The outer peripheral end of the lower surface of the plate is in contact with each other, and the screw center axis line is positioned horizontally in a horizontal configuration.

Therefore, according to the drying apparatus and the bag encapsulated feed cutting device provided by the above-described design, the discharge (transport) action of the bag and the breaking action of the bag cutting means according to the size (volume), the input amount and the screw feed amount of the bag encapsulated input It is formed in many forms.

Envelopes to be loaded into the chamber If the size of the encapsulated input is larger than the width of the screw plate of the spindleless spiral screw, the envelopes are conveyed to the front side by the screws regardless of the amount of the dry processing material to be fed into the chamber or the amount of conveyed per unit volume. Since a portion of the enclosed input is conveyed in contact with the inner circumferential end of the screw at the central cavity of the screw, a portion of the circumference of the envelope enclosed inputs is provided by a disc or toothed blade provided at the inner circumferential end of the screw to rotate with the screw. The cutting or breaking action is smoothly performed.

However, if the size (volume) of the envelope encapsulated inputs inserted into the chamber is smaller than the width of the screw plate of the spindleless spiral screw, the input volume into the chamber is small, and the capacity per unit volume does not exceed the width of the screw. The small envelope encapsulated inputs inserted into the chamber are brought into contact with only the lower screw plate surface of the spindleless spiral screw while being pushed forward while being placed only on the bottom of the chamber. There is no contact with the central cavity side at all, and thus no contact with the disc-shaped or toothed blades provided at the inner circumferential end of the central cavity side of the screw is performed, so that the enclosed inserts are cut off and cut or broken. I cannot expect it and therefore cannot achieve the drying efficiency of the expectation The contained powdery matter is a problem that cannot be stirred at all.

The problem of the cutting action of the envelope encapsulated input of the present invention is the drying of the envelope encapsulated inputs of various sizes and shapes in one envelope encapsulated input drying apparatus in which the size of the chamber or the spindleless spiral screw is limited to one standard. It is unsuitable as a non-spindle spiral screw type drying equipment facility in various waste incineration facilities, food processing facilities, or powdered materials agitating transfer equipments that should carry out a general purpose and efficient agitating transfer operation. It is a serious problem for the company's business.

The line design having the problem of cutting action of the envelope encapsulated insert has a problem in that the cutting blade can not be rotated when the screw member is thin in the installation structure of the envelope encapsulated insert cutting device provided in the spindleless spiral screw. In one preferred embodiment of the cutting means, there is a problem in terms of operation and maintenance.

One configuration presented as a preferred embodiment of the bag-enclosed insert cutting means provided in the spindle-free spiral screw of the line design, the arc-shaped spiral screw-free spiral screw over the predetermined length from the bottom of the inlet in the drying chamber With respect to the inner circumferential end, drill the semi-circular seating groove to a certain depth at each position where the circular arc is divided at regular intervals, and support the disk-shaped cutting blade with a fixed screw so that a part of the disk-shaped cutting edge protrudes more than the inner circumferential end of the spindleless screw. Configuration.

However, one embodiment of the configuration is that the sludge or the treated material is easily introduced into the gap between the seating groove and the disc-shaped cutting blade during use, the rotation operation of the disc-shaped cutting blade is stopped and the cutting action of the envelope-enclosed insert is reduced. This problem is expected to be solved by the complicated operation of separating the spindleless spiral screw from the chamber because the operator cannot enter and handle the chamber when the diameter of the chamber is small. There was a maintenance problem that was difficult to disassemble, separate and repair.

The constructions presented in another embodiment are provided with semicircular cutting edges having circular edges on circular arcs as cutting means, with fixed ends at both side ends of the semicircular cutting edges, and fixed intervals at the inner circumferential end of the spindleless spiral screw. In another embodiment, a triangular cutting blade is provided on the inclined side, and a fixed end is provided at both ends of the triangular cutting blade, and a fixed screw is provided at regular intervals at the inner circumferential end of the spindleless spiral screw. Fixed cutting edge configurations, such as the configuration to be installed by protruding, or as another embodiment as the configuration in which the triangular cutting blade lined on the inclined side as a toothed cutting blade formed with two triangular blades is disclosed, The left and right ends of the cutting blades are fixed in such a manner that the fixed cutting blades protrude at regular intervals to the inner circumference of the spindleless spiral screw. The configuration in which the protruding fixed end is formed is such that the sludge and the feeds are caught in the protruding fixed ends on both sides of the cutting blade while the spindleless screw rotates and the fixed cutting blades cut and crush the perimeter of the envelope-enclosed input. As the amount of sticking gradually increases and sticks, the cutting blades are covered with sludge after a considerable period of use, thereby losing the cutting function.

 The problem of the loss of the cutting function of the fixed cutting blade is the same as the problem of the deterioration of the rotary disk blade, when the diameter of the chamber is small, because the operator can not enter and process the chamber inside, the spindle-free spiral screw chamber Since it is solved only by the complicated work of separating from the material, there was a significant problem in the maintenance and repair for maintaining the smooth cutting function.

The present invention uses the conventional non-spindle spiral screw type drying apparatus as described above, and the bag encapsulated input cutting device applied to various waste incineration facilities, food processing facilities, or powdered agitating conveying apparatus for drying and transporting the bag encapsulated inputs. As provided to solve the problems of,

By the configuration for installing the envelope encapsulated input cutting means on the screw plate surface of the screw for the non-spindle spiral screw installed in the drying chamber,

For Envelope Encapsulated Inputs Inserted into the Chamber Inlet Regardless of the size (volume) of the envelope encapsulated inputs and the amount of feed (throughput) per unit volume of the screw, the envelope encapsulated inputs of various sizes to be inserted into the chamber can be reliably cut and broken. It is an object of the present invention to provide a bag-filled feed cutting device of a spindle-free spiral screw type drying device having high quality and versatility.

Another purpose is to form a rotary encapsulated feed cutting device of a spindleless spiral screw type drying device, regardless of the thickness of the screw member, to easily install the rotary cutting blade, and to adjust the installation position and angle, and to rotate the rotary cutting. It is an object of the present invention to provide a practical envelope encapsulated input cutting means in which the cutting function is continuously maintained and the maintenance is easy without the rotation of the blades being impossible to be deposited by the deposition.

According to the configuration of the envelope encapsulated input cutting device 200 according to another embodiment of the present invention, the cutting means of the envelope encapsulated input is fixed semi-circular arc-cutting on the front and rear screw plate surface 30b side of the spindleless spiral screw 30. Since only the blade 50 protrudes a predetermined height at a predetermined interval, compared to the configuration of installing rotary or fixed cutting blades on the inner circumferential end 30a of the shaftless spiral screw of the prior art, the inlet of the drying chamber 10 From (12) to the tip is discharged to the front end of the screw plate side can be carried out by the effective cutting and breaking (crushing) operation for the envelope encapsulation-type inputs that can be transported.

In addition, according to the configuration of the bag encapsulation-type insert cutting device 200 according to another embodiment of the present invention, the screw plate surface (30b) is typically formed at least two to three times wider than the screw inner peripheral end (30a) of a thin thickness By processing the fixing groove 55 in the through type, the size and thickness of the semi-circular arc cutting blade 50 can be adjusted in a wide range, and it is easy to select the installation position or adjust the installation angle according to the type of the dry process. Advantageously, the cutting blade fixing base 51 is accommodated in the thickness member of the screw plate surface 30b, so that the periphery of the semi-circular cutting blade 50 is treated with a smooth finish surface in which only the semi-circular cutting blade 50 protrudes. By preventing the process from being gradually fixed to the periphery and the edge of the cutting edge has the advantage that can maintain the cutting performance of the envelope encapsulated input continuously to normal performance.
