JPH01135455A - Buffing-polisher for inner surface of tank - Google Patents

Abstract

PURPOSE:To automatically buffing-polish the inner surface of a tank having a various values inner diameter by installing a plurality of expandable arms onto an elevating body which can be freely raised and lowered along a stay and installing a buffing device onto the outer edge of the arm. CONSTITUTION:An arm 8 is set into the perfect opened state by a cylinder device 14, and the extension quantity of a subarm 8a for the arm 8 is adjusted by an another cylinder device, and a buffing means 10 installed on the outer edge of the subarm 8 is pressed onto the inner surface of a tank T by a proper pressing pressure. A motor is driven in this state, and a raising and lowering body 5 is raised and lowered along a stay 1 through a pinion and rack. Then, the arm 8 is contracted, and the stay 1 is turned by a prescribed angle by a turning device R so that the buffing device 10 is set to a contiguous angle position, and the arm 8 is perfectly opened, and the vertical movement is carried out. Through the repetition of the above-described operation, all the inner peripheral surface of the tank T is buffing-polished in the vertical direction by the buffing device 10.

Description

[Detailed Description of the Invention] [Fields of Application of Sanmata-L] This invention is used in the fermentation industry to mechanically perform the inner surface huffing process of stainless steel fermentation tanks used for the fermentation of alcoholic beverages, etc. It is related to the device.

[Prior art and 18I issues] The main body that causes fermentation in a fermentation tank is microorganisms such as bacteria and yeast ILL. For this reason, in a new tank, m+
To prevent contamination with M4, buff the inside of the tank before use. Similar work is required if the contents of an existing tank are to be converted to a pond type. If the inner wall is insufficiently cleaned, the desired flavor cannot be expected from the fermented product.

Most fermentation tanks today are made of stainless steel and are extremely large. In the case of beer, it reaches about 8m in diameter and 20m in height.

Sakumata erected a dowel inside the tank and used it as a foothold to carry out the huffing process, but in this work, moving the huff in the forward direction is not considered effective for cleaning purposes. , only vertical movement is allowed.Movement from top to bottom is especially recommended.This is a know-how born out of many years of experience, and is a rule that workers must follow. It was requested that the buffing of the inner surface be done in accordance with the above rules.8 [Means for resolving the problem] A support was built in the center of the tank, and multiple arms that could be expanded and retracted into an umbrella tube were attached to it, pointing upwards. , and attach a buff to its tip. All arms are expanded and moved up and down along the support. Next, the arms are converged, the support is rotated to the adjacent angular position, and the arms are expanded again. 7, thereby making it possible to mechanize the entire process.During this process, the buff never comes into contact with the inner surface of the tank in the circumferential direction.

[Example] The zero fermentation tank T described in the drawings is a cylindrical body with a diameter of 8 m and a height of about 14 m. The upper surface is equipped with a lid '1'1, and the lower part forms a conical part 1'2 with a height of about 6 m, and the lower surface opens as a round hole with a diameter of about 50 mm.゛1 There is a round window in the center, and a bearing tube 'F3 with a window on the side is fixed to it.
Large round rods 1a and 1b are fixed to the ends. The support column 1 has a bearing E+1'3 installed in the round bar 1a section.
3, and is suspended by a nut 2 so that it can be rotated to the lid 1''I.A rack 3 is fixed to the side surface of the column 1.The 1-1 frame 4 has a bearing plate 12 [ Parallel bars are provided on both sides of the column, and the column bar 1b at the lower end of the column is inserted into the bearing of the bearing plate 1a and positioned.

The lower end of the round bar 1b is connected to a rotating device R to enable angular rotation of the column. The lifting body 5 has eight rollers 6 under the 11, and is built into the support column so that it can be raised and lowered. In order to avoid collision with the rack 3, the roller 6 has a central portion cut out (FIG. 5).

The shifting and crushing body 5 is further provided with a pinion 7 that engages with the ridges and ridges 3 and a pinion driving motor.

- One end of each arm 8 is pivotally attached to the elevating body at equal angles, and each arm 8 has a sub-arm 8a. The sub arm 8a is
Built into arm 8. The cylinder device 9 allows the arm to be moved in and out. Buff 10 at the tip of the secondary arm
is attached, and is rotationally driven via a belt 11 from a motor M attached to the sub-arm. The sub-arm is also attached with a suction device 12 that sucks in dust scattered during the buffing operation and discharges it to the outside of the tank. Like the elevating body 5, the sliding body 13 is equipped with eight upper and lower rollers 6, and can be freely lowered along the support at the upper part of the elevating body. tied together. Both ends of the connecting rod 15 are pivotally connected to the sliding body 13 and a part of the arm 8, respectively.

That is, the connecting rod 15 is expanded and contracted by the cylinder device 14,
The arm can be swung through the movable body, but the fully open state is completely converged to a predetermined inclination angle between the bones of the umbrella at both dead centers of the cylinder device.

The equipment assembly worker enters and exits and each member is brought in through the opening of the conical part 1 and 2. For the pillars, members with a length of about 2 m are brought in and multiple pieces are connected to obtain the required length. The reason why the strut is of the type 1 is that the conical portion '1'2 is thin and not suitable in terms of strength to support the load of the strut.

The present invention is configured as described above. The arm is fully opened by the cylinder device 14! Then adjust the sub-arm in and out using the cylinder device 9 to adjust the buff pressing force to an appropriate level. 51 in the second state. Raise and lower the crushed body. Next, the arms are converged and rotated by the length of the support using the one-turn device R so that the buff is at the bottom of the adjacent corner. +1 and fully open your arm.”
- Perform a downward movement. As this warps, the inner periphery is buffed in the vertical direction. If it is an arm or 4 trees, the support only needs to be rotated 90" in total. If you need to replace the buff, converge the arm 11 and turn the F/- crusher to the highest position by 1-5+'-.Zuroto No. 1.21
As shown by the chain line in J, the huff is located inside the bearing tube '3, so replace it by inserting your hand through the side window.
Also replenishes l1lf grinding.

[Song Dynasty] Everything will be done mechanically, and the harsh human labor will disappear.

All of the upper steps of the buff fF can be performed in the vertical direction, and the arm is extendable and retractable, so it can accommodate tanks with different inner diameters.
