Description

  The present invention relates to a scoop type compost stirrer and a compost raw material scraper device used in a compost fermenting facility, and in particular, increases the input amount of raw material into the compost fermenter, and the scoop type stirrer functions by the collapse of the compost raw material. The present invention relates to a scoop-type compost stirrer, a compost raw material scraper device, and a control method thereof.

  The general process for compost production is to press and knead compost raw materials consisting of livestock excrement, raw garbage, or organic waste sludge generated by sewage treatment, and leave it for a specified time after fermentation treatment in the fermenter. Is done by. Among these, regarding the process of fermentation treatment, a treatment method using a scoop-type compost stirrer has been proposed as effective in terms of quality, hygiene or environment.

  The scoop-type compost fermenting method means that a compost stirrer equipped with a stirring blade that sprinkles and lifts the compost raw material while rotating from the compost discharge port side to the raw material input port side on the rail installed at the upper end of the fermenter It is a processing method that promotes aerobic fermentation of compost by allowing the compost raw material to move backward by being self-propelled and including air therein.

  However, the compost raw material deposited in the fermenter also becomes a mountain with a height of about 1 meter to several meters, and when the stirring blade scoops out the raw material and propels it, the pile of sludge that has lost its foot is placed on the stirring blade. Sometimes it collapses. At this time, the motor of the electric motor that rotates the stirring blades (hereinafter also simply referred to as a “rotating machine”) cannot withstand the weight of the compost material that has collapsed, and becomes overloaded and stops the rotating function. As a result, the fermenting process is not only forced to be interrupted, but if this interruption is prolonged, the compost being fermented will undergo anaerobic fermentation due to lack of oxygen and the quality of the compost will deteriorate. is there.

  To deal with this problem, it is common to set the basic output of the rotating machine high in advance so that the compost stirrer does not become overloaded, but excessive power supply during normal operation is due to heavy machinery. There is concern that it will be a major economic loss.

  On the other hand, a situation in which a specific portion of the compost raw material is constantly kneaded by the rotating stirring blades tends to increase the viscosity of the raw material and generate a united mass. Once solidified, the sludge becomes dry and hard from the surface, making it difficult to be crushed, causing the above-mentioned collapse and causing overloading of the rotating machine, causing anaerobic fermentation without reducing the moisture inside the lump. It may also cause bad odor.

  About unity lump, the countermeasure is conventionally made by attaching a claw-like projection to the tip of the stirring blade. That is, the claws that rotate integrally with the stirring blades can prevent the sludge in the fermenter from being crushed and united.

  However, the above-mentioned conventional claw-like projections are uniformly arranged on all the stirring blades, and the united lumps that deviate from the rotation path of the projection are not crushed without hitting the claw, so that there is still a problem to be solved. I'm leaving.

  Therefore, in view of the above-mentioned problems of the compost fermentation treatment equipment, the present invention is a scoop-type compost stirrer and compost raw material that can prevent the stirrer from falling into a function-down state due to the load of the sludge slump that collapsed during the fermentation process. It is an object of the present invention to provide a scraper apparatus for use and a control method thereof.

  The configuration of the scoop type compost agitator of the present invention made for the purpose of solving the above-mentioned problem is that the support frame mounted on the moving rail installed on the upper end of the compost fermenter has a fermenter along the rail. It was moved forward from the rear compost discharge port side to the front raw material input port side by a moving electric motor (hereinafter also simply referred to as a moving device) and supported by a frame that was pivotally supported by the support frame and swingable up and down. In the compost stirrer that rotates the agitating blade with a rotating machine so as to turn the compost raw material back, the setting unit for the current value flowing through the rotating machine of the stirring blade and the retreat distance of the moving device of the stirrer, and the rotating machine A detection unit for a flowing current, a comparison calculation unit that compares the current value of the setting unit with the current value of the detection unit and calculates whether or not the set current value has been exceeded, and appropriately calculates the detection current value from the calculation unit An output control unit that receives an output indicating that the flow value has been exceeded, stops the rotating machine, outputs a backward command for a set distance to the mobile unit, and outputs a forward restart command to the mobile unit after the stirrer is moved backward. It has the drive control part which has.

  The scoop-type compost stirrer of the present invention has a configuration in which claw-like protrusions having irregular lengths are irregularly arranged at the tip of each rotating stirring blade, or at the left and right ends of each rotating stirring blade. It is good also as a structure which arrange | positions a claw-like processus | protrusion. Moreover, it is good also as a structure which equips the front of a compost stirrer with the scraper apparatus for compost raw materials which equalizes the compost raw material thrown into the fermenter.

  The structure of the scraper device for compost raw material of the present invention made for the purpose of solving the above problems is constructed at the upper end portion of the compost fermenter by a drive motor (hereinafter also simply referred to as a drive device) provided in the support frame. In the compost raw material scraper device that leveles the compost raw material in the fermenter while moving forward and backward along the moving rail, the agitator is operated by a signal from the self-propelled compost agitator installed in the compost fermenter Drive control having a detection unit that appropriately determines whether or not it is in the sampling time, and an output control unit that outputs the scraper device to the front end portion or the rear end portion of the fermenter when the stirrer is in operation. It has the part.

  The scraper device for compost raw material of the present invention is a compost raw material that smoothes the compost raw material in the fermenter while moving forward and backward along a moving rail installed on the upper end of the compost fermenter by a drive unit provided in the support frame. Object scraper device, object distance measuring device, detection unit for detecting the measurement value, distance setting unit from the scraper device to the self-propelled compost agitator, setting of the measurement value and setting unit of the detection unit A comparison operation unit that compares the values and appropriately calculates whether or not the set value is below the set value, and receives an output from the calculation unit that the measured value is below the set value, and issues a forward or backward command to the drive unit. It is good also as a structure provided with the drive control part which has the output control part which outputs and outputs a driving | operation resumption instruction | command to the said drive machine, when it is confirmed that a measured value exceeds the said setting value. Further, the scraping angle is provided in both the front and rear directions, or it is optional to have a retaining wall at its upper end and to be movable so that the inclination angle can be changed as appropriate.

  The structure of the control method of the compost agitator of the present invention made for the purpose of solving the above-mentioned problem is that the raw material forward from the compost discharge port side behind the fermenter along the moving rail installed on the upper end of the compost fermenter In the control method of a compost stirrer that turns a compost raw material by turning a stirring blade provided on a base that is pivotally supported on a support frame and can be swung up and down while moving forward by a moving machine to the inlet side, When the detected current value flowing through the rotating machine exceeds a set current value, the operation of the motor of the rotating machine and the moving machine is temporarily stopped, and after the stirrer is moved backward by an appropriate distance by the moving machine, the rotating machine The operation of the motor is resumed, and when it is confirmed that the detected current value flowing through the rotating machine is lower than the set current value, the moving machine is controlled to resume the forward movement of the agitator. It is.

  The control method of the compost stirrer of the present invention is such that the stirrer blades are rotated in the opposite direction while the compost stirrer is retracted by a suitable distance or until the motor operation of the rotating machine is resumed after the retreat. In addition, the operation of the motor of the rotating machine may be controlled.

  The configuration of the method for controlling the scraper device for compost raw material of the present invention, which has been made for the purpose of solving the above problems, is scraped while being advanced or retracted by a drive unit along a moving rail installed on the upper end of the compost fermenter.

When the value is less than 1, the scraper device is controlled to advance or retreat to the front end portion of the compost fermenter by the drive unit.

  The present invention, in the fermentation treatment process in the compost fermentation equipment, when the pile of compost raw material collapses on the stirring blade and the current value flowing through the rotating machine exceeds the preset current value, the compost stirrer advances and stirs By stopping the rotation of the blades and once moving the stirrer, it is possible to prevent the compost raw material from being shaken off from the stirring blades and stopping the function of the stirrer from an overload state. In addition, the claw-like protrusions of irregular length arranged at the tip or left and right ends of each stirring blade can prevent sludge from agglomerating. The risk of collapsing can be avoided, and the amount of raw material charged into the fermenter in a single processing step can be increased. As a result, the production efficiency of compost is improved, and the processing process is not interrupted for a long time, so it is completely possible to prevent bad smell and quality deterioration from anaerobic fermentation due to lack of oxygen. The effect that it can be prevented is demonstrated.

  Prior to the description of the embodiment of the present invention, a scoop type compost stirrer (hereinafter simply referred to as a stirrer M) generally used in a compost fermenter will be described with reference to FIG. In FIG. 5, 1 is a compost fermenter for storing and fermenting the compost raw materials 4a and 4b, and 2 is a moving rail installed in the longitudinal direction of the upper end of the compost fermenter 1, and the agitator M moves back and forth. It is a rail to do. Reference numeral 3 denotes a support frame that is a carriage that supports the stirrer M, and m <b> 2 is a motor-type mobile unit that is provided at the front portion of the support frame 3 and supplies a propulsive force in the front-rear direction. Reference numeral 6 denotes a stirring blade for scooping up the compost raw material 4a. In the embodiment, the stirring blade 6 is formed of an angle-shaped member having a width of about 3 meters and made of a hard material such as metal or synthetic resin. The agitating blade 6 is wound around a flexible transport belt 62 with a chain 5 that circulates on an endless track by being wound around a drive wheel W1 and a corresponding driven wheel W2 that obtains power from a rotating machine m1 by a motor provided on a support frame 63. It is fixed by fixing means such as bolts and nuts, and the constituent members 5, 6, 62 are united and turn along the support frame 63 to turn over the compost raw material 4 a. Hereinafter, the chain 5, the stirring blade 6, the transport zone 62, and the support frame 63 are also collectively referred to as a turning device 60.

  The support frame 63 that supports the stirring blade 6 and the transport belt 62 is pivotally supported on the support frame 3 by a swing shaft 61 (in FIG. 5, an axis perpendicular to the paper surface). It can swing up and down within a certain range up to 90 degrees (in this embodiment, about 50 degrees is selected as a design value). Thereby, it is possible to carry out in a state where the turn-back device 60 is lifted and laid down at the time of return path or line change after work.

  Here, “turning” means that the turning device 60 indicated by the solid line in FIG. 5 is set to the inclination angle indicated by the phantom line, and the stirring blade 6 that rotates while the agitator M is moved forward is placed in the fermenter 1. It refers to a series of operations in which the introduced compost raw material 4a is scooped up in the rotating lower end region 6b of the turning device 60, and is transported and dropped to the rotating upper end region 6t. This is because the piles of the compost raw material 4a that have accumulated in the fermenter 1 and have reached a considerable height are crushed little by little by the stirring blade 6, and evenly contacted with the outside air to supply sufficient oxygen and stir. The purpose is to promote aerobic fermentation of the later raw material 4b.

  On the other hand, since the turning operation is performed in a state where the turning device 60 is slanted downward with respect to the advancing direction of the stirrer M, the compost raw material 4a in the fermenter 1 is gradually added from the tank bottom side by the stirring blades 6. Therefore, it is normal to contact the stirring blade 6 with a gentle inclined surface as shown by the phantom line in FIG.

  However, since the moisture content of the compost raw material 4a varies greatly depending on the composition or location, a difference in viscosity is likely to occur. As a result, as shown by the solid line in FIG. 1, the accumulated sludge forms a steep slope, and when this collapses on the stirring blade 6 as shown in FIG. 2- (a), the weight of the compost raw material 4a becomes the rotating machine. As described above, it is overloaded with respect to m1 and this causes a problem.

  Therefore, the scoop type compost stirrer M of the present invention eliminates the above-mentioned inconvenience by controlling the operation of the stirrer M even when sludge collapses by a drive control unit C1 (hereinafter also simply referred to as a control unit C1). Therefore, this point will be described below with reference to FIGS.

  In FIG. 1, the stirrer M according to the present invention includes a control unit C1 at the front portion of the support frame 3, and the mobile unit m2 is managed by the control unit C1 to move forward, stop, and reverse. As illustrated in FIG. 3, the control unit C1 includes an ammeter A, a current value of the rotating machine m1 and a backward distance setting unit F1 and a detection unit D1, and a comparison calculation unit c11 and an output control unit. The comparison calculation unit c11 appropriately performs a calculation process at a sampling time, and the output control unit c12 controls and manages the operation of the motors of the rotating machine m1 and the moving machine m2 in response to the result. Here, the rotating machine m1 is connected to an ammeter A for measuring a current value i flowing therethrough, and the current value i measured and detected by the detection unit D1 is transferred from the detection unit D1 to the comparison calculation unit c11. And is compared with the set current value i1 previously set in the setting unit F1 as a current value that does not hinder the agitator M from performing normal switching.

  When the current value i is lower than the set current value i1, the output control unit c12 maintains the rotating operation of the rotating machine m1 and the forward operation of the moving machine m2, and continues the turning operation. On the other hand, when the detected current value i exceeds the set current value i1, the rotating operation of the rotating machine m1 and the forward operation of the moving machine m2 are stopped. And the stirrer M is once retracted based on the command of the reverse distance set with respect to the moving machine m2. After that, when the comparison calculation unit c11 confirms that the detected current value i is lower than the set current value i1, the output control unit c12 outputs a command for the rotating operation of the rotating machine m1 and the forward operation of the moving machine m2. The reversing operation of the stirrer M is restarted.

  That is, when the raw material 4a collapses on the stirring blade 6 in the turnover operation, the load on the rotating machine m1 and the supply current value i increase due to the weight, and the output of the comparison calculation unit c11 determined by performing this processing is received. The output controller c12 stops the rotation of the stirring blade 6 and the forward movement of the stirring machine M before the rotating machine m1 stops its function due to overload, and then moves the moving machine m2 backward to compost on the stirring blade 6 By sliding down the raw material 4a, the situation before the collapse is recovered. In the present invention, in order to slide down the compost raw material 4a more reliably, the stirring blades are used while the compost stirrer M is moved backward or until the motor of the rotating machine m1 is restarted. It is optional to control 6 to rotate in the reverse direction.

  A flowchart for explaining the operation of the controller C1 is as shown in FIG. That is, starting, first, the magnitude of the current value i detected by flowing into the rotating machine m1 and the set current value i1 is compared and determined by the calculation unit c11. Next, on the condition that the detected current value i is larger than the set current value i1, the operations of the rotating machine m1 and the moving machine m2 are stopped. If the detected current value i is a numerical value smaller than the set current value i1, the process returns to the start. After the operation of the rotating machine m1 and the moving machine m2 is stopped, an appropriate distance reverse command is issued by the moving machine m2. After reversing the appropriate distance by the moving machine m2, the turning operation of the turning machine m1 is first restarted, and here the detected current value i and the set current value i1 are compared again. When the detected current value i is smaller than the set current value i1, the operation of the mobile device m2 is resumed and the operation returns to the normal operation state. When the detected current value i is larger than the set current value i1, the process returns to the set distance by the mobile device m2.

  The tip of the stirring blade 6 of the stirrer M according to the present invention may have a configuration in which short claw-like projections h1 and long claw-like projections h2 are randomly arranged, whereby the compost raw materials 4a and 4b are united into a lump. What can be avoided is as described above (see FIGS. 6 and 7). The short claw-like projections h1 and the long claw-like projections h2 are preferably formed of a hard material such as metal or synthetic resin so that sludge can be crushed. In the present embodiment, it is constituted by two types of claw-like projections h1 and h2 of long and short, but it is arbitrary that it is constituted by more types of claw-like projections.

  The present invention may be configured such that claw-like projections h3 similar to those described above are disposed on the left and right ends of the stirring blade 6. This claw-like projection h3 rotates integrally with the stirring blade 6 to peel off the sludge adhering to the side retaining wall surface of the fermenter 1 and, like the claw h1 and h2, the generation of malodor is generated. Contributes to prevention and quality improvement as compost.

  The explanation of the method of controlling the operation of the stirrer M to avoid overloading when sludge collapses is as described above. On the other hand, if sludge does not accumulate in a mountain shape in the fermenter 1, it collapses in the first place. The stirrer M can be continuously turned over.

  Therefore, the scraper device S for compost raw material of the present invention is provided with the scraper device S as a self-propelled or integrally provided in the front part of the self-propelled stirrer M, and the compost raw material 4a piled in the fermenter 1 is stacked. Since the above-mentioned inconvenience has been solved by scraping down and smoothing, this point will be described below with reference to FIGS.

  9 and 10, the compost raw material scraper device S includes a support frame 64 movable along the moving rail 2 and a scraping angle 65 supported on the support frame 64 by a support member 66. The The support frame 64 is integrally provided with a driving machine m3, whereby the scraper device S can be moved back and forth along the moving rail 2. In addition, the rail which the scraper apparatus S moves is not restricted to the said rail 2 for a movement, Arrangement | positioning a separate rail in the fermenter 1 is arbitrary. In addition, the scraper device S disposed integrally with the front portion of the self-propelled stirrer M does not need to include the drive machine m3.

  The scraping angle 65 is inclined at an appropriate angle with respect to the horizontal plane, and is designed so that sludge can be scraped off efficiently with the smallest resistance. In addition, it is arbitrary to design the inclined surface to be movable so that the angle of inclination of the scraping angle 65 can be appropriately changed according to the characteristics of the raw material composition. Moreover, it is preferable to provide a retaining wall for preventing sludge from flowing backward at the upper end of the inclined surface so that the pile of the compost raw material 4a can be surely scraped off. Further, it is optional to arrange the scraping angle 65 in both the front and rear directions so that the sludge scraping effect can be obtained even in the return path (see FIG. 11).

  As described above, the compost raw material scraper device S in this embodiment can be self-propelled by the drive machine m3. Therefore, it is necessary to control this so that the operation of the scraper device S does not interfere with and collide with the operation of the compost stirrer M that is self-propelled along the moving rail 2 while performing the turning operation. A control method will be described below.

  12 to 13 determine whether or not the self-propelled stirrer M is operating based on a signal from the stirrer M, and when the stirrer M is operating, the scraper device S reaches the front end of the fermenter 1. A compost raw material scraper device S that controls to avoid collision with the stirrer M by moving forward and waiting is displayed.

  A drive control unit C2 (hereinafter also simply referred to as a control unit C2) provided in the scraper device S has a detection unit D2 that detects a signal that informs the operating status of the compost stirrer M, and an output that controls the operation of the drive unit m3. It consists of the control part c21. The detection unit D2 determines whether or not the stirrer M is operating based on the signal sent from the stirrer M, and outputs the result to the output control unit c21. When it is determined that the stirrer M is in operation, the output control unit c21 stops the operation of the motor of the driving machine m3, advances the scraper device S to the front end of the fermenter 1, and puts it into a temporary standby state. Thereby, the behavior of the scraper device S and the stirrer M does not interfere with each other, and collision can be avoided. In addition, when it is determined that the stirrer M is not in operation, it is optional to perform control so that the sludge leveling operation by the scraper device S is continued. In addition, when the scraper device S performs work behind the compost stirrer M, the scraper device S is controlled so as to retract to the rear end of the fermenter 1 and wait.

  14 to 15 show a drive control unit C3 so as to avoid a collision with the stirrer M by measuring the distance to the compost stirrer M that runs behind the scraper device S by the object distance measuring device E. A compost raw material scraper device S controlled by (hereinafter also simply referred to as a control unit C3) is displayed.

  The control unit C3 provided in the scraper device S includes an object distance measuring device E that measures the distance to the object, a detection unit D3 that detects the measured value d, a set distance setting unit F3 that is used as a reference for comparison calculation, and a comparison It is comprised from the calculating part c31 and the output control part c32. The object distance measuring device E provided in the control unit C3 measures the distance to the compost agitator M that runs rearward, and the measurement value d measured and detected is output from the detection unit D3 to the comparison calculation unit c31. The scraper device S is compared with a set value d1 set in advance in the setting unit F3 as a numerical value representing a minimum interval at which the scraper device S does not interfere with or collide with the agitator M. The comparison calculation unit c31 appropriately executes the comparison calculation process at the sampling time, and the output control unit c32 that receives the result controls and manages the operation of the motor of the driving machine m3.

  When the measured value d exceeds the set value d1, the output control unit C3 maintains the forward operation of the driving machine m3 and continues the sludge scraping work by the scraper device S. On the other hand, when the measured value d falls below the set value d1, the operation of the drive machine m3 is once stopped, and then the scraper device S is advanced to the front end of the fermenter. Thereby, the behavior of the scraper device S and the stirrer M does not interfere with each other, and collision can be avoided. After that, the comparison operation unit c31 performs a size comparison between the set value d1 and the current measurement distance d, and when it is confirmed that the measurement value d exceeds the set value d1, the control unit c31 controls the driving machine m3. It is optional to output a command for restarting the operation and to control the scraper scraping operation by the scraper device S to be resumed.

  Although the said Example is description about the scraper apparatus S which all work in front of the stirrer M which self-propels a rail, when working behind the stirrer M, it waits in the fermenter 1 rear end part. Alternatively, it may be configured to be controlled with respect to resumption of forward operation.

  As a result, the compost raw material 4 a accumulated in the fermenter 1 is scraped down low, and it is possible to avoid the sludge that has become agglomerated slumps falling to the stirring blade 6. In addition, the scraper device S can level the sludge so that the amount of the compost raw material 4a that can be stored in one fermentation process can be increased.

  The present invention is as described above, and in the fermentation treatment process in the compost fermentation facility, the pile of accumulated sludge collapses on the stirring blades of the compost stirrer and the current value flowing through the rotating machine exceeds a preset value. Sometimes, stop the agitator from moving forward and the rotation of the agitating blade, and once the agitator is moved back by an appropriate distance, the raw material is slid down from the agitating blade, preventing the stirrer from stopping its function from the overload state. Not only can it be made, but the irregular claw-like projections of irregular lengths arranged irregularly at the tip of each stirring blade can crush the compost raw material evenly and prevent sludge from becoming a unity mass. The processing process will not be interrupted, and the raw material input in one fermentation processing process can be increased, so the efficiency of compost production is improved, and anaerobic fermentation due to lack of oxygen leads to bad smell and quality deterioration Toi Also because there is an effect that it completely prevented the state of affairs, scoop composting stirrer, it is extremely useful when applied to compost raw material for the scraper device.
