Description

V. Description of the Invention (1) [Technical Field of the Invention] The present invention relates to a kitchen waste processing device capable of rapidly decomposing kitchen waste and suppressing the generation of odor as much as possible, in order to greatly reduce the amount of kitchen waste. . [Conventional technology] In addition to the kitchen waste discharged from the general court, there are also kitchen waste generated from kitchens such as restaurants, canteens, food industry, and school feeding. The disposal of food waste ’is usually incinerated or discarded in public facilities. However, due to environmental protection and space problems, the processing costs have been increasing year by year. Therefore, the simple outsourcing of food waste has gradually become difficult and has become an environmental problem. Therefore, the way to deal with kitchen waste at the source of kitchen waste has become a new cognitive trend in society. Common methods for processing wide-remaining materials are: (). In a state where the microorganisms in the fermentation tank are easily activated, the kitchen waste is decomposed by microorganisms by heating, stirring, etc., and the processed materials are used as organic fertilizers or Fermentation treatment method using special fertilizers with soil improvement effect; and (2) Putting kitchen waste into a trough filled with sawdust or coffee grounds, etc., and then making the kitchen waste almost complete by throwing Decomposition-decomposition-type treatment methods that decompose into water and carbon dioxide are generally known, and are gradually adopted. In particular, the decomposition and destruction type treatment method of (2), which essentially eliminates food waste (although it is less than 100% * but can be reduced to a considerable degree), has become the object of reward in recent years. Therefore, the present invention provides an improved treatment device for the treatment method. The conventional decomposition and elimination type food waste treatment device is, for example, in a treatment tank.

ΙΗΗΗ IBM Page 4 C: \ Progiam Files \ Patent \ 15826.ptd 424 005 V. Description of the invention (2) ~ Set a substantially horizontal rotation axis' on the rotation axis to fix most of the stirring rods in a vertical manner. Rotating, the wood chips or coffee grounds and kitchen wastes filled in the tank are searched and mixed with the propeller type stirring rod. In addition, in order to consider the conveyance of contents, there is a so-called screw stirring device. [Problems to be Solved by the Invention] However, in the conventional propeller-type kitchen waste processing device, although its cross-section is a cylindrical processing tank, its stirring effect is insufficient. In order to complete the reaction of the decomposition processing, it takes more than 24 hours to process it. Efficiency does not meet general needs. In addition, if a square-shaped processing tank is used, dead space will be generated, so that the content at the dead angle position cannot be stirred, so the subtraction and reduction processing cannot be performed. If a spiral agitation device is used, the contents will only be pushed forward, and a considerable mixing effect cannot be expected. In addition, because the cutting device is not attached to the processing device of the conventional device, the kitchen waste cannot be miniaturized. If there is a relatively large piece of kitchen waste, it must be crushed to a certain size before being put into use. So it is not easy to use in operation. In addition, because of the long treatment time, there are also many opportunities to generate odors. In order to remove odors, a deodorizer must be installed separately, so the burden on the installation is also heavy. '' The present invention was developed by the developer to improve the problem points of conventional processing devices. The purpose of the invention is to provide a method for applying food waste in a short period of time as soon as possible; to decompose and eliminate (decrease) processing to greatly improve processing efficiency, At the same time, a large piece of kitchen waste can be simply miniaturized and an easy-to-operate kitchen waste processing device. Yet another object of the present invention is to provide a method for mixing the present inventors, etc.

The bottom of the processing tank is substantially parallel and Two rotating shafts which can rotate in opposite directions to each other are provided at intervals, and a plurality of cutting blades extending from the shaft portion in the radial direction are respectively fixed along the axial direction of the rotating shaft. At the same time, along the axial direction of each rotating shaft, The two blade-shaped mixing blades at the front end of the cutting blade are spirally connected and fixed. The rotation direction of the two adjacent rotation axes is viewed from the axial direction, the right axis is rotated in the clockwise direction, and the left axis is rotated in the counterclockwise direction. The contents between the two axes are turned from the bottom to the top to form The upturned part β is also described in the kitchen waste treatment device described in item 2 of the scope of patent application of the present invention. When there is a cooling part with dew condensation, a gutter is attached to the cooling part to collect water droplets generated by the dew. A drain pipe for collecting water droplets is connected to the gutter. In order to generate dew condensation, it is necessary to maintain a temperature difference of 5 or more between the cooling part and the temperature in the tank. As described in item 3 of the scope of patent application of the present invention, the two band-shaped mixing systems are located at opposite positions on both sides of the rotation shaft, and have a defect shape at the ends opposite to each other.

Description of the invention (4) The cutting blade holding a band-shaped stirring blade is viewed from the axial direction, and the cutting edges on both ends of the cutting blade are slightly 180 to each other. Positional relationship. In items 6 to 8 of the patent application scope of the present invention, the cutting edge is twisted at the middle portion, and the fixed angle of the cutting edge on the rotating shaft side is 20 to 80 to the shaft portion. , And the fixed angle of the cutting edge on the side of the mixing knife is 5 ° to 45 ° with respect to the shaft portion. [Embodiment of the invention] The embodiment of the present invention will be described with reference to the drawings as follows: FIG. 1 is an exemplary view showing a kitchen waste processing apparatus 1 according to the present invention. The kitchen waste processing device is composed of: a box-shaped processing tank 1 for containing kitchen waste and cooking waste materials; at the bottom of the processing tank, two horizontal rotating shafts 2a, 2b disposed at approximately parallel and spaced intervals via bearings; The majority of the cutting blades 3 extending from the axial direction of the rotating shafts 2a and 2b to the radial direction from the shaft portion, and fixed to the axial direction at a predetermined interval, and along the axial directions of the rotating shafts 2a and 2b, The front ends of the cutting edges are connected in a spiral shape, and two band-shaped mixing knives 4 and the like are fixed respectively. The treatment tank 1 is formed of a rigid metal plate, and a lid opening door (not shown) that can be opened and closed is opened on the upper part. On one side, a driving portion is provided for rotating the rotating shafts 2a, 2b. From the axial view, handle the groove! The bottom portion corresponds to the rotation track of the floor mixing blade 4, and is formed into a cylindrical shape with two adjacent arcs. In addition, the bottom portion is also divided into two grooves. In order to maintain the temperature suitable for the decomposition state in the tank when processing the contents 6, a heating device (not shown) with a suitable temperature adjustment function is built in the bottom of the processing tank 1. The driving part of the rotating shaft can be used in any form, as long as the two horizontal rotating shafts 2a, 2b can rotate at opposite speeds to each other at any speed. example

The description of the fifth invention (5) For example, if the rotating shafts 2a and 2b are driven by separate speed reducers to drive Ma Jian5 to rotate, or the 1 motor and the gear mechanism are synchronized to rotate the two rotating shafts, etc., both the rotating shafts 2a, The direction of rotation of 2b is viewed from the side view of FIG. 1 (b). 'Make the right rotation axis 2a clockwise.' Left rotation draw 2b is counterclockwise. 'In order to flip the contents from bottom to top between the two axes. To be. The interval between the two rotating shafts 2a and 2b is preferably arranged as close as possible within a range where the stirring blades of the two shafts do not contact each other. Fig. 2 shows a rotating shaft 2a (the same applies to the rotating shaft 2b) on one side having the cutting blade 3 and the stirring blade 4. The cutting knives set in the radial direction of the rotating shaft are arranged in two rows along the axial direction with a certain trajectory, and the front ends of the cutting knives in each row are connected by a spiral search knife. In other words, the front ends of the cutting blades 3A, 3B, 3C, 3D, and 3E (all at the same height) are connected with the stirring blade 4-1, and the other cutting blades 3a, 3b, 3c, 3d, and 3e (full At the same height) is connected by another mixing blade 4-2 "again as shown in Figure 3, the cutting blades 3A and 3E and the cutting blades 3a and 3e at the end of each row are offset from each other by about 18 〇. Relationship location configuration. The cutting knives in between are allocated at an appropriate angle (unequal angle or equal angle), and the rows of cutting knives 3A to 3E and the cutting center to center ^ are located on both sides of the shaft and are relatively arranged. Therefore, the number of twisting turns of each of the blades 4-1 and 4-2 connecting the cutting blades is also constant, and is approximately 180. 15〇. To 19. Within the range) 'becomes a semi-circular shape in the axial direction. Although the main function of the cutting knife 3 is to finely cut this, ^, you can cut the contents (kitchen waste) in the groove, but it can also play a stirring role. At the same time, the rotation Convoluted flows have contributed. In particular, as shown in Figure 4,

V. Description of the invention (6) The cutting knife 3 is twisted from the middle to the opposite direction, and the cutting knife 3 'on the sleeve side can be rotated to the shaft by 20 ° to 80. The angle range α is inclined, and the cutting blade 31 'on the stirring blade side is set to 5 with respect to the shaft portion. To 45. The angle range of tilting tilt 'is therefore used to play a role in the function of the cutter, the fine cutting of the grinding residue and the swirling flow action. In other words, 'the content is cut by the cutting blade 3 with a steep inclination near the axis of rotation', and at the same time, the cutting blade 3 with a gentle inclination is pushed toward the right angle of the axis of rotation so that the content and the Since the stirring blade 4 is easy to contact, it can contribute to the effect of swirling flow. The optimal inclination angles of the cutting blades 3 ', 3 " are about 45 ° and about 150. . In FIG. 4, for the sake of convenience, only the shape of both end surfaces of one cutting blade 3 is indicated by 3 ′ and 311. In addition, the inclination of the cutter with respect to the shaft portion on one side is formed in the same direction as the inclination of the cutter with respect to the shaft portion on the other side. In addition, although the main function of the stirring blade 4 is the contents in the stirring processing tank 1, of course, it can also play a role of cutting the contents. At the same time, its rotation can multiply with the rotation of the cutting knife, The swirling flow of the contents in the tank contributes. In particular, in order to generate the swirling flow effect of the contents in the tank, as shown in Fig. 2, the two stirring blades 4-1 and 4-2 were formed with defects at one end of the opposite side. That is, the portion between the left end of the shaft body and the cutting blade 3a X, and the portion y between the right end W2 and the cutting blade 3E, is not provided with a stirring blade within a certain distance (of course, there is no cutting blade). The defect of the mixing blade 4 and the reverse rotation of the two rotating shafts, plus the action of the cutting blade and the mixing blade, as shown in Figure 1 (b), can be used to change the content (base material + kitchen waste + touch Media) turned up between the rotating shafts, and the upturned part is formed when the rotating speed of the rotating shaft is slow, forming a relatively short mountain shape as shown in 6a,

C: \ ProgramFUes \ Patent \ 15826.ptd Page 9 4 24 005 V. Description of the invention (7) When the rotation speed is fast, it can be a high mountain shape like 6b. In the present invention, it is desirable to make the turned-up portion higher. For example, in Figure 1 (b), the distance h between the position of the foot of the upturned part and the horizontal plane passing through the axis of the rotation axis should be greater than 1/3 of the radius of the stirring blade. To maintain this height, the rotation speed of the rotating shaft is preferably 3 to 9 rpm. From this speed range, the contents can be circulated and swirled between the two cylindrical grooves. The flow of the contents (base material + kitchen waste + catalyst) 6 is shown in the plan view of FIG. 5. The contents thrown into the tank are rotated in the same direction and should be mutually opposite directions due to the cutting blades and stirring blades of the two rotating shafts (in the mode shown in Figure 5), so the arrows in Figure 5+ As shown in A and B, there will be positive and negative logistics in the central part of the tank. At the same time, the reverse flow of A and B can form an upturned part in the central part, so that the content flows from one side of the tank to the other. Inside the slot. During the vertical movement of the contents, when the contents are turned up along the axial parallel side walls lb and Id, the cutting blade and the stirring blade are drawn in and moved downward to the wall portions la, At the lc position, it reaches the lowest position, where it is caught between the rotating shafts, and becomes a form of rising again. Therefore, in the present invention, the content is temporarily turned up between the two axes, and air is mixed therein to activate the enzyme to obtain a good decomposition state. At the same time, 'the bottom of the treatment tank 1 is formed into a cylindrical shape, Therefore, the above-mentioned swirling flow action * does not cause dead angles of the contents in the tank, which enables the circulation to be performed smoothly ', and in the process of this cycle, the kitchen waste can be miniaturized, and the substrate and Stirring of food and catalyst mixtures can promote the rapid decomposition and elimination (reduction) of kitchen waste. The number of cutting knives can be increased or decreased by the length of the stirring blade (rotating shaft), and the lowest

C: \ Program Files \ Patent \ 15826.ptid Page 10 ^ 24005 V. Description of the invention (8) Limit to 2 pcs. In order to exert the above function, the number of the stirring blades must be two. Not more than two or more. However, the number of torsional turns is independent of the length of the rotating shaft 'and remains at about 180 °. The materials of the cutting blade and the stirring blade are preferably made of metal such as stainless steel. If necessary, they can also be made of non-metals. Referring to Fig. 6, another embodiment of the present invention will be described. [Beta] With the progress of the treatment of kitchen waste in the treatment tank, a large amount of water is generated. The apparatus shown in Fig. 6 has the same box-shaped processing tank 1, two rotating shafts 2a, 2b, a cutting blade, and a stirring blade as those shown in Fig. 1. However, the bottom is divided into two slots as the heating space 7, and a cover 9 is provided on the upper part of the processing tank 1. The cover 9 is provided with a freely-closable kitchen waste input door 8, and a zigzag cooling is formed inside the cover 9 Space 10. The heating space 7 is heated by an appropriate heating mechanism or the temperature inside the processing tank is optimized. The cooling space 10 is built to cool the environment in the processing tank and cause condensation on the surface. Have proper cooling mechanism. In order to produce dew condensation, the temperature difference between the temperature of the trough and the cooling space must be maintained above 5 ° c in principle. Therefore, the control device to achieve this purpose must be attached to the cooling mechanism. In FIG. 6, reference numeral 11 is a water collecting channel ′ provided at an appropriate position on the lower end of the cooling space 10 or the cover portion 9. The water collecting channel receives water droplets dripping due to dew condensation. Since the gutter 11 is connected to the drain pipe 12, etc., the collected water droplets can be discharged out of the tank through the above-mentioned gutter 11 and drain pipe 12 ', and the gutters 11 at each position can be collected in a drainage The tube 12 may be appropriately distributed in a plurality of places and discharged. As shown in Figure 6, the device ’can

C: \ ProgramFiles \ Patent \ 15826.ptd Page 11 V. Description of the Invention (9) Almost all of the points (9) are dew-condensed and discharged, so that the odor can be almost eliminated. It is preferable to use a porous material such as sawdust, coffee breaks, or rice hulls that is easily attached to the microorganisms (enzymes) for destruction in the processing tank. The so-called kitchen waste is targeted at leftovers, leftovers, fish and shellfish, meat crumbs, bones, and paper. You don't need to subdivide the kitchen waste in advance, you can invest directly. Furthermore, in the present invention, the treatment device having the above-mentioned structure is used, and in order to activate the function of the enzyme, a special catalyst is preferably used in combination, thereby rapidly eliminating food waste. That is to say, the processing device of the present invention is configured by reasonably arranging two rotating shafts that are relatively reversed, a partially-blended stirring blade, and a cutting blade whose angle is changed up and down, so that the contents are generated. Good stirring, cutting and swirling flow, make the catalyst evenly disperse the catalyst 'at the same time', and make the input kitchen waste evenly dispersed in the mixture of catalyst and substrate. In addition, the coarse and massive kitchen waste can be miniaturized to increase the contact area with the catalyst. At the same time, it does not need to add additional enzymes or bacteria, and can be formed in the treatment tank to produce the most aerobic properties. The environment of microorganisms is therefore 'decomposed in the shortest time possible to eliminate the processing waste.
