TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device for eliminating clogging of garbage in a screw press type dehydrator for compressing and dewatering garbage discharged from a kitchen or the like.
[0002]
[Prior art]
A screw dewatering machine is used to dewater and solidify garbage. As such a processing device, for example,
[Patent Document 1] As shown in Utility Model Publication No. 57-42640, a screw is provided inside a screen cylinder provided with a large number of dehydration holes, and a screw is attached to an opening at the upper end of the screen cylinder with a hinge, It has a holding lid that is pressed against the end of the screen cylinder with a spring via a lever.The garbage supplied from below the screen cylinder is transferred by a screw, pressed against the holding lid, compressed and solidified, and solidified. A processing apparatus has been proposed in which garbage is pushed out of the holding lid against a spring to be discharged.
Also,
[Patent Document 2] Japanese Patent Application Laid-Open No. H10-34387 discloses that the present applicant treats strong fibrous garbage such as cabbage and burdock to make the surface of the lid that comes into contact with solid matter conical and drive the screw. When overload of the motor is detected, a structure is proposed in which the lid is moved in the axial direction to increase the gap between the screen cylinder and facilitate discharge of the processed material.
[0003]
In addition,
[Patent Document 3] Japanese Patent Application Laid-Open No. 10-167867 discloses that a screw conveyor for transferring composting material into a processing cylinder and a rotary blade for cutting and friction-kneading an object to be processed are provided with a gate at an outlet of the processing cylinder. In the figure, the pressure required for friction kneading of waste is set, and the gate is opened when the detected pressure of the screw conveyor reaches the set upper value.
Also,
[Patent Document 4] Japanese Patent Application Laid-Open No. H11-104504 discloses a method of closing brown rice sent to a milling roll by a screw feeder in order to increase the residence time of the milling roll in accordance with the degree of milling in order to increase the residence time. A control device for a rice milling machine in which a plate is provided and the force of a tension spring pressing the resistance plate is adjusted by a control unit in accordance with the degree of milling is shown.

[Problems to be solved by the invention]
However, if the holding lid that closes the discharge port of the screen dehydrator that compresses and solidifies the garbage is attached with a hinge and pressed with a spring, strong fibrous garbage such as cabbage and burdock will Fibers are entangled and hardened in the screen cylinder, or they cannot be moved smoothly due to entanglement in the dewatering hole, and solidified garbage can not be pushed up the holding lid, clogging the opening, making it impossible to discharge Or the screw may be overloaded to damage the motor.
[0005]
For this reason, as described in Patent Literature 2, when the holding lid of the screw dehydrator for compressing and solidifying the garbage is mounted so as to be movable in the axial direction of the screen cylinder, the adjustment structure of the holding lid is complicated. And was not practical.
Patent Literature 3 and Patent Literature 4 disclose a technique in which a transfer means using a screw detects a pressure in a processing cylinder and opens a gate when the pressure reaches a set pressure value. The method also adjusts the pressure required for processing in the processing chamber, and no means has been proposed for resolving clogging near the gate, which hinders discharge of the processed material.
[0006]
The present invention relates to a device for compressing garbage using a screw dehydrator, which detects clogging of garbage by overload of a motor driving a screw and forcibly resists the force of a spring pressing a lid of a discharge port. The purpose of the present invention is to provide a structure in which the holding lid is opened by the user and the clogging is eliminated.
[0007]
[Means for Solving the Problems]
For this reason, a screen cylinder provided with a large number of dehydration holes surrounding a screw for transferring garbage, a holding lid attached to a discharge opening of the screen cylinder with a hinge, and the holding lid is pressed against the screen cylinder with a predetermined pressing force. In a garbage compression processing device provided with a pressing spring, a lid opening device for separating a holding lid from a screen cylinder against a spring is provided, and the lid opening device is operated by an overload signal of a motor driving a screw. Thus, garbage clogged near the discharge port of the screen tube is discharged from the discharge port.
In addition, this lid opening device is configured such that, for example, a wire is connected to the other end of a lever having one end connected to the holding lid, and the wire is pulled by a linear head or the like to open the holding lid, and a screw is provided. Operated by the overload signal of the drive motor. The wire may be pulled by winding, and the wire may be replaced with a link mechanism.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
This will be described with reference to the embodiment shown in FIG.
1 is a machine frame, 2 is an outer cylinder of a screw dehydrator installed in the machine frame, and 3 is a screw in the outer cylinder 2 rotated by a motor 4. Reference numeral 5 denotes a screen cylinder surrounding the screw 3 and having a number of dehydration holes (not shown). 6 is a holding lid attached to the discharge port 7 of the screen cylinder 5 with a hinge 8, 9 is a garbage supply port, 10 is a drain port, 11 is a lever connected to the holding lid 6, and 12 is an end of the lever 11 and a machine. A tension spring is used as a spring provided between the mounting pins 13 of the frame 1, and presses the holding lid 6 against the discharge port 7 of the screen cylinder 5. 14 is a discharge chute.
Reference numeral 20 denotes a lid opening device for opening the holding lid 6 against the spring 12, comprising a wire 21 connected to the lever 11 and a linear head 22 for pulling the wire 21, and receiving an overload signal 23 from the motor 4. The linear head 22 pulls the wire 21 according to a command from the controller 24.
[0009]
When garbage is supplied from the supply port 9 into the screen tube 5, the garbage is transferred toward the discharge port 7 by the screw 3 rotated by the motor 4, and pressed against the holding lid 6 to be dehydrated. The dewatered garbage is pushed up by the holding lid 6 by the transfer force of the screw 3 and is discharged to the discharge chute 14. However, if strong fibrous garbage such as cabbage or burdock is supplied, the uncut fibrous garbage is removed. Are entangled and hardened in the screen cylinder 5, or are entangled in the dewatering holes of the screen cylinder, so that the holding lid 6 cannot be pushed up and the discharge is prevented.
In such a state, the motor 4 is overloaded, an overload signal 23 is sent to the controller 24, and the linear head 22 rotates, for example, a pinion meshed with a rack by a command from the controller 24, The wire 21 is pulled in the direction of the arrow, and the holding lid 6 is forcibly opened from the discharge port 7 against the spring 12 via the lever 11 to discharge the solid garbage solidified in the screen tube 5.
Although the wire 21 is provided in the lid opening device 20 in the illustrated embodiment, a link mechanism may be used, or the wire 21 may be wound up instead of the linear head 22.
[0010]
【The invention's effect】
The present invention surrounds a screw for transferring garbage, a screen cylinder having a large number of dehydration holes, and a pressing lid provided at an outlet of the screen cylinder and pressed against the outlet of the screen cylinder with a predetermined pressing force, In a device for compressing garbage conveyed by a screw, a lid opening device for forcibly opening a holding lid from a discharge port of a screen cylinder is provided, and the lid opening device is operated by an overload signal of a screw driving motor. When fibrous garbage solidifies in the screen cylinder, the holding lid can be forcibly opened to discharge the garbage that has solidified. There is an effect that clogging of garbage can be eliminated and dehydration can be performed efficiently.
