Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a high-pressure washer suitable for cleaning slice retainers, sausage pipes, and the like.

(Prior art and its problems) Conventional techniques have been used to clean slice retainers for boiling sliced ham and sausage logs, and sausage pipes for supplying dough from a kneading machine to a filling machine for filling sausage into film. One high-pressure washer was inefficient and very time-consuming.

Among these, an example of a conventional high-pressure washer for sausage pipes is one in which a single nozzle is drilled into the nozzle tip, and water, etc. is sprayed forward; Although it is suitable for cleaning the outside of the pipe, it is difficult to remove pieces of mixed meat that adhere to the inside of the pipe due to the poor jetting angle of the water. If the valve is the main valve and is connected to the high-pressure washer with a long rubber hose, when you open the main valve and approach the object to be cleaned while spouting high-pressure water or steam, the surrounding equipment may be exposed to high-pressure water, etc. is applied vigorously,
There was a risk of contaminating it.

In addition, in the case of a type in which the valve for cleaning fluid is attached to the pipe of the high-pressure washer, the weight of the high-pressure washer is heavy, making it unsuitable for people with limited strength or for long-duration cleaning.

Furthermore, high-pressure washers in which the nozzle of the nozzle tip is perpendicular to the axial direction of the pipe have been known, and although this type of high-pressure washer can effectively remove pieces of meat from inside the pipe, When this type of valve with a main valve opens and approaches the object to be cleaned while spouting out high-pressure water or steam, the high-pressure water or steam is more powerful than the above-mentioned high-pressure washer and hits surrounding equipment and people. It was dirty and dangerous. Another drawback was that pieces of meat, water, etc. flowed out in front of the pipe and splashed onto the operator's body, staining the operator's body. In particular, cleaning using steam with this type of high-pressure washer is dangerous because steam or hot water may splash onto the operator's body.

The present invention eliminates the drawbacks of the conventional methods mentioned above, and enables high-pressure washing to effectively clean difficult-to-clean areas such as the inside of pipes, and also allows the operator to clean and safely clean without splashing sewage. It was developed for the purpose of providing a machine, and in particular, the type that can use the main valve as is, can be used in any area of a large factory by connecting a long hose to freely approach the object to be cleaned. In addition, since there is no valve at hand, the weight of the high-pressure washer can be reduced, making it easy for even people with less power to operate it.

(Means for Solving the Problems) In order to achieve the above object, the present invention has a socket at the tip of a fluid supply pipe, which has a diameter larger than that of the pipe, and which has a diameter approximately the same as that of the socket and has a pointed point at the front. A head-like conical tip is formed, a nozzle inclined at an acute angle with respect to the axis is bored in this tip, and a nozzle tip is connected to the tip with a disk having approximately the same diameter as the socket. The outer periphery of the nozzle tip is covered with a cylindrical nozzle cover that has a slightly larger diameter and opens forward, and after the fluid ejected from the nozzle collides with the nozzle cover, the fluid is directly ejected from between this cover and the disk. The rear end wall of the nozzle cover is locked to the socket by the elastic force of a spring interposed between the rear end wall and a spring seat protruding from the supply pipe, and further Connect the rod to the nozzle cover above,
By pulling the grip connected to the rod rearward, the nozzle cover is moved rearward against the elastic force of the spring to expose the nozzle, and the fluid to be ejected from the nozzle is directly ejected to the outside. It is something.

(Function) When cleaning the inside of a sausage pipe, etc., the nozzle cover is moved backward through the rod against the elastic force of the spring to expose the nozzle, and water, steam, etc. are removed from here. Cleaning is performed by jetting out fluid and colliding the jetted fluid directly against the inside of the sausage pipe, etc. with strong pressure, and usually locking the rear end wall of the nozzle cover to the socket using the elastic force of a spring. This prevents the fluid from flowing out from here, and also allows the fluid ejected from the nozzle to collide with the nozzle cover, and then allows the fluid to flow out from between the cover and the disk provided on the nozzle. This reduces this pressure and prevents the fluid from scattering to other locations.

(Example) Hereinafter, the present invention will be explained with reference to an example shown in the drawings.

FIG. 1 shows an embodiment of a high-pressure washer 1 according to the present invention, in which a threaded portion 3 of a fluid supply pipe 2 that supplies cleaning fluid such as steam or water is equipped with a socket having a diameter larger than that of the pipe 2. 4 is screwed onto the socket 4, and a nozzle tip 5 having approximately the same diameter as this socket 4 is screwed onto the socket 4.

This nozzle tip 5 has a disc 6 protruding from its tip, the diameter of this disc 6 is equal to the outer diameter of the nozzle chip 5, and the disc 6 is arranged coaxially with the nozzle chip 5. There is. The pointed conical tip 7 adjacent to the disk 6 has a virtual apex angle of 60 degrees formed on the extension of the conical tip 7. Six nozzles 8 with a diameter of 1.5 mm are bored at equal intervals in the circumferential direction. This nozzle 8 therefore has an angle of 60 degrees with respect to the axis of the nozzle tip 6.

A cylindrical nozzle cover 9 having a slightly larger diameter is disposed on the outer periphery of the nozzle tip 5 so as to be movable in the axial direction of the pipe 2. This nozzle cover 9 has a rear end wall 10.
is configured to be hooked onto the socket 4 and prevented from coming off. This nozzle cover 9 is configured to be movable so that it can take a position that covers the outer periphery of the nozzle 8 of the nozzle chip 5 and a position that exposes the nozzle 8 of this nozzle chip 5. The nozzle cover 9 also protects the outer periphery of the nozzle 8 of the nozzle tip 5 by the elastic force of a coil spring 12 interposed between the rear end wall 10 and a spring seat 11 provided around the outer periphery of the pipe 2. It is biased in the covering direction.

The spring 12 may be a weak spring having enough elasticity to prevent the nozzle cover 9 from descending when the pipe 2 is placed in a vertical position so that the nozzle tip 5 is located at the upper end.

A handle 13 for gripping by hand is protruded from the pipe 2, and a rod 14, one end of which is fixed to the nozzle cover 9, faces near the handle 13 and is bent at a right angle. Grip part 1
5 together with the handle 13, the nozzle cover 9 is pulled to the right in FIG. 1 against the elastic force of the spring 12, so that the nozzle 8 of the nozzle tip 5 is exposed to the surroundings.

The rod 14 is configured to move while being supported by a guide 16 projecting from the pipe 2, and another handle 17 is provided projecting from the pipe 2 as shown in FIG. Further, a valve 24 for a cleaning fluid such as steam or water may be provided in the pipe 2 as shown in FIG.
It may be provided at the source to control the supply of fluid to the rubber hose 25 to which the pipe 2 is connected.

Next, cleaning of the slice retainer in the above-mentioned embodiment will be described.

When cleaning the outside of the slice retainer, water or steam is supplied to the pipe 2 in the state shown in FIG.
If the nozzle tip 5 is placed in its normal position without pulling, the fluid ejected from each nozzle 8 of the nozzle tip 5 will be deflected by hitting the inner peripheral surface of the nozzle cover 9, and the fluid will be deflected between the nozzle cover 9 and the disc 6 of the nozzle tip 5. The liquid is sprayed straight ahead of the nozzle cover 9 along the axis of the nozzle cover 8 . Therefore, since the fluid hits only the area to be cleaned, dirt can be removed well and the fluid does not scatter to other areas.

Next, when cleaning the inside of the slice retainer, as shown in FIG.
Open the door 20 of 9 and insert the tip of the high pressure washer 1 from here. At this time, since the nozzle cover 9 is located around the nozzle 8 of the nozzle chip 5, the fluid ejected from each nozzle 8 of the nozzle chip 5 does not scatter around.

Then, with the nozzle tip 5 completely inserted into the slice retainer 19, the rod 14 is pulled to expose the nozzle 8 of the nozzle tip 5. Then, since the fluid from each nozzle 8 is ejected in the radial direction, it hits the inner surface of the slice retainer 19 with strong pressure and removes dirt well. Therefore, by gradually advancing the high-pressure washer 1, the inside of the slice retainer 19 is cleaned. Note that since the inside of this slice retainer 19 is relatively wide, fluid and the like will not flow back forcefully.

In order to clean the inside of the sausage pipe 26 with the high-pressure washer 1 according to the present invention, as shown in FIG. Insert the tip of the high pressure washer 1 from one end of the sausage pipe 26 until the nozzle tip 5 is completely attached to the sausage pipe 2.
6, the rod 14 is pulled to expose the nozzle 8 of the nozzle tip 5. Then, the fluid from each nozzle 8 collides with the inner circumferential wall of the sausage pipe 26 at an angle of 60 degrees with respect to the axial direction with strong pressure, thereby effectively removing dirt such as pieces of meat. In addition, since the sausage pipe 26 has a relatively small inner diameter, even if the fluid flows back toward the high-pressure washer 1 side,
Since it hits the nozzle cover 9, backflow of the fluid is prevented, and there is no risk that the operator's clothes will be soiled by the fluid containing dirt such as pieces of meat. In particular, when the fluid is steam, it is dangerous for the operator to get burns if exposed to this steam, but as mentioned above, the high pressure washer 1 according to the present invention is safe because it has the nozzle cover 9. It is.

[Effect of idea]

Since the present invention has the above-mentioned configuration, by connecting it with a rubber hose using a main valve provided in factories, etc., the weight of high-pressure washer for sausage pipes, which requires a particularly long fluid supply pipe, can be reduced. It is lightweight and easy to operate, and by attaching a long hose, cleaning can be carried out anywhere in the factory even if the object to be cleaned is far away from the main valve installed in the factory.

Also, if the object to be cleaned is far away,
It is necessary to approach the object to be cleaned while discharging the cleaning fluid, but at this time, the nozzle cover covers the outer periphery of the nozzle tip, weakening the jetting of the cleaning fluid and only letting it flow forward, so it does not disturb the surrounding area. It does not contaminate equipment or people, and prevents dangers caused by steam and boiling water.

Furthermore, when cleaning pipes, if you hold the trigger together with the handle, the nozzle cover will be pulled against the force of the spring and the nozzle will be exposed to the surroundings, allowing you to effectively and efficiently clean the inside of pipes, etc. can. This spring may be weak enough to have enough elasticity to prevent the nozzle cover from falling when the pipe is placed in a vertical position, so it does not require much force even if it is held for a long time.

Furthermore, when the nozzle is exposed, the nozzle cover is located closer to the operator than the nozzle tip, so the operator is not exposed to back-flowing fluid and has the advantage of being able to work cleanly and safely. .
