Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cleaning device for a koji making conveyor such as a koji making device or a malting device.

(Prior Art) Generally, spray cleaning of water is used for cleaning conveyors. However, since the conveyor-type koji-making device is a new product, there is no conventional technique for cleaning the koji-making device.

(Problems to be solved by the invention) In the cleaning of a koji-making conveyor formed by connecting perforated plates, not only the cleaning of removing the substances clogging the perforated plates but also the cleaning of the joint between the perforated plates, Cleaning the front and back surfaces is also important.

However, the above function cannot be achieved simply by spraying the cleaning water onto the perforated plate.

An object of the present invention is to provide an apparatus for efficiently cleaning a koji-making conveyor formed by connecting perforated plates.

(Means for Solving the Problem) As a cleaning device for a koji-making conveyor formed by connecting perforated plates, the following means are adopted.

(1) The washing nozzle header is provided in the reversing part of the conveyor.

(2) Plural rows of cleaning nozzle headers are provided in the width direction of the conveyor.

(3) The cleaning nozzle header is reciprocated in the width direction.

(4) Set the wash water pressure to a high pressure and select the wash water amount appropriately.

For example, a nozzle having a water pressure of 10 kg / cm ² G and a water amount of about 10 l / min is used, the nozzle shape is a 60 ° flat spray, and the dimension related to the perforated plate is 200 mm.

(Operation) The conveyor can be uniformly washed by reciprocating the nozzle header in the width direction of the conveyor. By providing multiple rows of nozzle headers in the width direction of the conveyor,
The front row header performs preliminary cleaning or rough cleaning, and the rear row header performs final cleaning. Even if only the front row header is used, it is possible to sufficiently remove the clogging of the perforated plate openings and to clean the surface of the perforated plate. However, by providing the rear row header, the cleaning effect can be improved.

(Example) In FIGS. 1 and 2, 1 is a koji making conveyor formed by connecting wide perforated plates operating at a controlled speed, and 7 is a frame of the conveyor.

As shown in FIGS. 1 and 2, the cleaning device 10 according to the present invention includes a nozzle header 2, a cleaning nozzle 3, a reciprocating mechanism 4, a cleaning water receiver 5, a header support roller 6, a seal plate 8, and a side seal plate. It consists of 9.

The cleaning device 10 is installed in the reversing part of the conveyor 1, and is equipped with the cleaning nozzle 3 in the nozzle header 2 for cleaning the width direction of the conveyor 1 at the same time. The nozzle header 2 has a reciprocating mechanism 4
Is reciprocated by the header support roller 6 via a driving force transmission mechanism such as a link mechanism. As the support or guide for reciprocating the nozzle header 2, a bearing for linear movement may be used in some cases, but a method of supporting and guiding with a concave roller 6 as shown in FIGS. 1 and 2 is used. When used under such adverse conditions (moisture, foreign matter, reciprocating motion, length, absorption of reaction force of nozzle pressure), there is no mechanical trouble, maintenance is easy, and the cost is low. Since the header support roller 6 is mounted on the fixed side, the header support roller 6 is positioned and fixed more reliably than the frame 7 or the like. The cleaning nozzle 3 is attached to the nozzle header 2 so as to be replaceable, and this attachment is performed by the conveyor 1
Make a right angle to. The relative size and number with respect to the conveyor 1 are determined by the moving speed of the conveyor 1, the reciprocating speed and stroke amount of the nozzle header 2, the width dimension of the conveyor 1, the pattern dimension of the cleaning nozzle 3, the water pressure, and the flow rate. In addition, in order to prevent the cleaning water from scattering during cleaning and adversely affecting the product, and to prevent contamination, sterilization and propagation, odor, decay, etc. around the equipment due to cleaning water, sterilization, and scattering of foreign substances, cleaning water A wash water receiver 5 is provided so that foreign matters and foreign matter will not be scattered. The cleaning water receiver 5 covers the surroundings and is inclined at the lower part to prevent foreign matters from accumulating in the cleaning water. A drainage port is provided at the lower part to connect to an external treatment device. Shall lead to. A seal plate 8 and a side seal plate 9 are attached around the cleaning water receiver 5 to completely seal the conveyor 1.

As described above, the main parts or devices are constituted, but as the material thereof, stainless steel, plastic, rubber or the like is mainly used depending on the environment where water is handled.

In order to most effectively clean the front and back surfaces of the wide conveyor 1 and the openings, a cleaning device 10 is provided at the reversing portion of the conveyor 1 as shown in FIG. It may be provided in the section.

A suitable installation position of the cleaning device 10 will be described with reference to FIG. When cleaning is performed at the straight line portion of FIG. 3 (a), the front and back surfaces of the conveyor 1 can be sufficiently cleaned, but the perforated plate and the joint between the perforated plates are likely to be in a dead zone, and cleaning may be insufficient. However, if the conveyor 1 does not have a tail portion, such a problem does not occur.

In order to eliminate such a cleaning failure, if the cleaning device 10 is installed in the reversing part of the conveyor 1 as shown in FIG. 3 (b), the perforated plate as well as the front and back surfaces of the conveyor 1 can be cleaned. As for the seam of the perforated plate, the conveyor 1 is inverted, so that in the case of a straight line, the dead zone is released and sufficient cleaning can be performed. In addition, since the cleaning is performed in a state where the conveyor 1 is inclined, the flow of cleaning water during cleaning smoothly flows down the surface of the conveyor 1, and foreign substances that have been removed or cleaned are reattached to the surface of the conveyor 1. Can be prevented. By equipping the cleaning nozzle 3 of the nozzle header 2 and reciprocating the cleaning, the entire width can be cleaned even with a small number of cleaning nozzles, which contributes to saving water (energy saving) and providing an inexpensive device. Further, since the cleaning nozzle 3 reciprocates, the cleaning water pressure also changes depending on the timing when the cleaning water is hit and when it is not hit, so the cleaning effect is better than when cleaning is performed at a constant pressure.

(Effects of the Invention) The cleaning device for a conveyor according to the present invention has a plurality of rows of nozzle headers arranged along the width direction of the koji-making conveyor formed by connecting perforated plates, and the nozzle headers. A member for movably supporting in the width direction of the conveyor, a member for reciprocating the nozzle header in the width direction of the conveyor, and a plurality of cleaning nozzles provided in the nozzle header, thereby providing the following effects. Have.

(1) Fully automatic cleaning of castin cleaning, which has been conventionally performed manually, becomes possible.

(2) Cost and energy savings can be achieved by optimally designing the cleaning conditions.

(3) The surrounding environment also improves.

(4) Not only the cleaning effect, but also unattended fully automatic operation does not cause any germ growth or adhesion.
