Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a cleaning device for efficiently cleaning livestock products and solid agricultural products.

``Prior art'' Conventionally, as a device for cleaning the disassembled parts of solid agricultural crops and livestock products, a rotating drum is placed in a water tank filled with cleaning water, and a spiral blade is fixed to the central axis of the drum. to carry out internal transfers,
It has been proposed that an object to be cleaned inserted into one side of the drum is transferred to the other side while being stirred in the cleaning water, and is automatically cleaned and discharged.

``Problem that the invention aims to solve'' This is convenient in that it automatically cleans and discharges the drum, but because the inside of the drum is divided by the central shaft and the blades, it is difficult to clean the object compared to the size of the object to be cleaned. Unless the rotating drum is formed to have a large diameter, the objects to be cleaned are often clogged or damaged by the blades, making it difficult to operate smoothly and continuously. Also,
Because the inside of the drum is divided by the central shaft and blades, the cleaning water in the tank is not forced to circulate, which has the disadvantage that dirt accumulates in the water and quickly reduces cleaning efficiency. .

In order to solve the above-mentioned drawbacks of the conventional device, the present invention has been developed by fixing blades in a spiral shape to the inner peripheral wall of a cage-shaped rotating drum installed in the cleaning tank so that the center of the drum is hollow. In addition to configuring the center of the drum so that the objects to be cleaned and the water can easily move, an overflow tank is attached to the rear side of the cleaning tank, and a water guide tube is connected to the bottom of the overflow tank, and the tip of the pipe is connected to the bottom of the overflow tank. This is intended to increase the cleaning efficiency by communicating the front part of the cleaning tank, which is the input side of the items to be cleaned, and creating a water flow that circulates the cleaning water inside the cleaning tank.

"Means for Solving the Problems" The present invention is a cleaning device characterized by having the following configuration as a means for solving the above problems.

First, a cage-shaped rotating drum is placed horizontally in a cleaning tank so that its lower half is submerged, and is supported so as to be rotated by a drive device. The wings are fixed in a spiral shape so that the center of the drum is hollow. The reason why the center of the rotating drum is hollow is to form a space in the center of the drum so that the object to be cleaned can move easily and water flow can easily occur. In addition, the reason why the blades are spiral-shaped is to prevent the objects to be washed from being transferred by running water in a short period of time. This is to ensure that

Next, a drain pipe having an overflow opening and a bottom opening is provided near the rear end of the cleaning tank.
The overflow opening is for discharging separated floating debris from the drain pipe by overflow, and the bottom opening is for discharging settled debris together with water through the drain pipe.

Further, an overflow tank is attached to the rear side of the washing tank, which is the side from which the objects to be cleaned are sent out, so as to communicate with the washing tank. The reason why the overflow tank was provided at the rear side of the washing tank was to avoid interfering with the movement of the objects to be washed and the flow of water.

A water guide tube is connected to the bottom of the overflow tank, and its tip is connected to the front part of the cleaning tank where the items to be cleaned are input, and the communication part between the water guide pipe and the front part of the cleaning tank is connected to the bottom of the overflow tank. A rectifier is provided to allow water to flow from the inlet side to the outlet side of the washing tank, and a screw is provided at the inflow part to the water guide pipe at the bottom of the overflow tank to allow water to be sent to the water guide pipe by driving a motor. It is provided. This is a mechanism for circulating the water in the overflow tank.The drive of the screw sends the water to the water conduit pipe and uses it as the driving force to generate the water flow.The outflow port is squeezed at the rectifier to create pressure in the water. This system is designed to increase the speed of water flowing from the input side to the output side of the cleaning tank.

"Function" In this invention, after water is supplied to the cleaning tank and the overflow tank, and the cleaning water is filled up to the overflow line in the cleaning tank, the screw in the overflow tank is driven while rotating the cage-shaped rotating drum, and the water is introduced into the water guide tube. A water flow is created at the front of the cleaning tank, and the speed of the water is increased by a rectifier at the front of the cleaning tank, and the water flows through the basket-shaped rotating drum, so that the cleaning water circulates in the cleaning tank, overflow tank, and water pipe. This is what I did. In this device, the rotating drum is rotated in the cleaning tank at the same time, so
Inside the cleaning tank, the cleaning water is constantly stirred by the blades of the basket-shaped rotating drum while creating a water flow that rapidly flows from the input side to the output side, creating a state in which quite strong turbulent water flows. Therefore, the loaded items to be washed, such as livestock products and agricultural products, are effectively washed in the strongly turbulent water inside the rotating drum while moving rearward. In this case, since the center of the rotating drum is hollow, it is possible to maintain the turbulent water that is occurring, and while the object to be cleaned is exposed to the turbulent water, it is regulated by the blades and moves smoothly to the delivery side over a predetermined period of time. and is automatically discharged from the rotating drum.

On the other hand, dirt such as garbage that has been washed, separated and floated by the turbulent water is allowed to overflow from the overflow opening and is discharged from the drain pipe, and dirt that has been washed, separated and settled at the bottom of the washing tank is drained from the bottom of the washing tank. It is discharged from the bottom opening through the water pipe.
Then, water is automatically supplied to the cleaning tank and the overflow tank by the amount of cleaning water that is discharged and insufficient, so that a predetermined amount of cleaning water is always circulated in the cleaning tank.

``Example'' Hereinafter, an example of the present invention will be described in detail with reference to the drawings. 1 is a cleaning tank, and a cage-shaped rotating drum 2 is arranged horizontally so that its lower half is submerged in the cleaning tank 1. This is rotatably supported by rollers 3, 3, 3, 3. A vane 4 forming a hollow state in the center of the rotary drum 2 is fixed to the inner circumferential wall of the rotary drum 2 in a spiral manner. A sprocket portion 2a is provided at one end of the rotating drum 2, and a chain 6 is connected to a sprocket 5a of a motor 5, so that the rotating drum 2 is rotated by the drive of the motor 5.

Above the input side of the cleaning tank 1, there is provided an input chute 7 for objects to be cleaned, and below the input chute 7 there is a guide net plate 8 for guiding the objects A to be cleaned into the basket-shaped rotating drum 2. It is arranged.

Further, a roller chute 9 is provided outward from the rear end edge on the delivery side of the cleaning tank 1 to send out the object A to be cleaned passing through the basket-shaped rotating drum 2. A shower pipe 10 is provided.

Further, a drain pipe 13 having an overflow opening 11 and a bottom opening 12 is provided near the rear end of the cleaning tank 1 . In the figure, 14 is the bottom opening 12
This is an on-off valve that regulates drainage from the water.

Further, an overflow tank 15 communicating with the cleaning tank 1 is attached to the rear side of the cleaning tank 1, which is the delivery side of the object to be cleaned A. In the figure, 16 is a float that senses the water level of the cleaning tank 1 and the overflow tank 15, and is linked with the on-off valve 14 of the automatic water supply section 17, and the on-off valve 17 is appropriately opened and closed according to the water level signal detected by the float 16.
The water level is always maintained at a constant level.

A water guide pipe 18 is connected to the bottom of the overflow tank 15, and the tip thereof communicates with the front part 1a of the washing tank, which is the input side of the object A to be washed. and,
A rectifier 19 is provided in the communication portion between the water conduit 18 and the front portion 1a of the cleaning tank to allow water to flow from the input side to the output side of the cleaning tank 1.

As shown in the figure, the rectifying section 19 includes an adjustable aperture plate 20, its support body 21, and an adjustment mechanism 22 that can adjust the angle of the aperture plate 20. The aperture plate 20 is located in the communication section and is arranged so as to be adjustable in angle so as to constrict the outlet 23. By squeezing the outlet 23 in this manner, pressure is generated in the water, and the speed of water flowing from the outlet 23 on the input side of the cleaning tank 1 to the outlet side is increased.

Furthermore, a screw 25 is provided at the inflow portion of the water conduit 18 at the bottom of the overflow tank 15 to allow water to be conveyed to the water conduit 18 by being driven by a motor 24.

Note that 26 in the figure is a drain port provided at the bottom of the water pipe 18.

When using the above embodiment, automatic water supply section 1
Water is supplied from 7 to fill the cleaning tank 1 and overflow tank 15 with cleaning water, and while the motor 5 is driven to rotate the cage-shaped rotary drum 2, the motor 24 is further driven to rotate the screw 25. Then, the cleaning water is turned into a water flow by the screw 25 in the overflow tank 15, passes through the water guide tube 18, and is sent to the front part 1a of the cleaning tank, where the water pressure is increased by the adjusted throttle plate 20. The speed of the water flowing from the input side outlet 23 to the output side is increased and flows into the cage-shaped rotating drum 2, and due to the agitation caused by the rotation of the rotating drum 2, it becomes turbulent water and moves to the rear, and after the cleaning tank. After hitting the end wall, the cleaning water that went around to the side is
The water flows into an overflow tank attached to the side and is circulated.

Therefore, when the object A to be cleaned, such as the heads and feet of livestock pigs and cows, is inputted from the input chute 7, the object A to be cleaned inside the basket-shaped rotary drum 2 is washed away by the strong jet stream and the agitation flow by the blades 4 of the rotary drum 2. is sent to the rear while being effectively cleaned in a short period of time.

At this time, dirt such as blood floating in the washing water is discharged from the overflow opening 11 via the water pipe 13, and settled dirt is discharged from the bottom opening 12.
The water is discharged from the drain pipe 13 through the drain pipe 13. The shortage of discharged washing water is automatically replenished from the automatic water supply section 17 to the overflow tank 15, so that washing is always performed with fresh water. The washed object A is discharged from the rear end of the basket-shaped rotary drum 2 onto the roller chute 7, where it is finished with water from the shower pipe 10 and sent to the next process.

``Effect of the invention'' As described above, the present invention supports a cage-shaped rotating drum in a washing tank so as to be rotatable, and the inner circumferential wall of the cage-shaped rotating drum has a hollow center. The blades are fixed in a spiral shape, and an overflow tank communicating with the cleaning tank is attached to the rear side of the cleaning tank, which is the delivery side of the cleaning tank, and a water guide tube is installed at the bottom of the overflow tank. A screw is connected to the front part of the washing tank, which connects the tip end thereof to the front part of the washing tank where the items to be washed are inputted, and the inflow part to the water pipe at the bottom of the overflow tank is provided with a screw that can send water to the water pipe by driving a motor. , the cleaning water is circulated by sequentially flowing through the cleaning tank, the basket-shaped rotating drum, the overflow tank, and the water pipe. Therefore, the objects to be cleaned are constantly washed with flowing water, making it possible to wash them efficiently.

As mentioned above, the basic feature of this invention is that the cleaning water is circulated and the water is used for cleaning.However, in order to improve the cleaning efficiency, the following points have been partially added. Another major feature of this invention is that it has been devised.

First, a rectifier is provided in the communication section between the water conduit and the front part of the cleaning tank to allow water to flow from the input side to the outlet side of the cleaning tank, and the water flow generated by the drive of the screw is directed to the rectifier. By squeezing the outlet to create pressure in the water and increasing the speed of water flowing from the input side to the output side of the cleaning tank, and by rotating the cage-shaped rotating drum, there is no turbulence inside the rotating drum. The cleaning effect is enhanced by creating running water and washing the object with this turbulent water.

Second, the reason why the blades are spirally fixed to the inner circumferential wall of the cage-type rotating drum so that the center of the drum is hollow is to form a hollow in the center of the rotating drum to prevent the objects to be cleaned from moving. In addition, the reason why the blades are spiral is to prevent the objects to be washed from being transferred by the running water in a short period of time. This has the effect of ensuring that the product is transported reliably while being cleaned once in a while.

Thirdly, since a drain pipe having an overflow opening and a bottom opening is provided near the rear end of the cleaning tank, the overflow opening allows separated floating debris to be discharged from the drain pipe by overflow. The settled waste can be discharged along with water from the opening at the bottom via the drain pipe. In other words, the difference in the specific gravity of the dirt separated by washing is used to efficiently remove dirt from the areas where dirt accumulates in the circulating water, thereby preventing dirt in the washing water as much as possible and increasing the washing efficiency for a long time. I was able to maintain it over time.

Fourthly, an overflow tank that communicates with the washing tank is attached to the rear side of the washing tank, which is the delivery side of the cleaning tank, because the flow of washing water in the washing tank is The direction of the flow is divided into the flow to the rear and the flow of water circulating to the overflow tank, thereby ensuring that the objects to be cleaned are moved to the rear end of the washing tank, and on the other hand, the circulation The water flow is also made smoother than the flow to the rear of the cleaning tank.

That is, the present invention creates a water flow using the water in the overflow tank that is separated from the water to be washed, and then converts it into a high-speed strong jet that is circulated as washing water and sent into the washing tank, thereby removing the waste water during washing. The floating waste is discharged to one side, so the clean washing water becomes a strong jet of water and washes the items to be washed.
This results in a cleaning device with extremely high cleaning efficiency.
