Abstract

(57) [Abstract] [Purpose] The inside of the mixer is washed by flowing pressured water to the inside of the mixer, and by rotating the spray pipe (2) with the cylinder (4), the ceiling and Enables detailed cleaning of the side walls. [Structure] Utilizing kneading water when kneading and manufacturing concrete, the inside of the mixer is washed with pressure water pressurized in a pressure tank in each batch through a water sprinkling pipe inside the mixer, and a cylinder (4) The water spray pipe is rotated by to expand the cleaning range, and the solenoid valve (14) is used to make it switchable, and the pressure water is jetted to the water spray pipe installed in the concrete hopper to clean the concrete hopper.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to cleaning the inside of a fresh concrete batcher plant mixer (hereinafter referred to as a mixer) and the inside of a concrete hopper.

[0002]

[Prior Art]

 As a conventional mixer cleaning means, a strong pressure type water rinsing jet machine was used after the completion of one day of concrete kneading and manufacturing work, and the mixer was manually cleaned. The fresh concrete, mortar, etc. that have been scattered on the ceiling during the kneading process and have adhered to it are congealed during cleaning, and cannot be removed only by the high-pressure washing jet for injection, such as electric picks. Had to peel off. It is very time-consuming and labor-intensive, and it is dangerous to work in the mixer, so labor-saving, efficient, and safe cleaning techniques have been demanded.

[0003]

[Problems to be solved by the device]

 The problem to be solved by the present invention is that cleaning the raw concrete and mortar adhering to the ceiling and side walls inside the mixer is labor-intensive, dangerous, and extremely time-consuming.

[0004]

[Means for Solving the Problems]

 The means taken by this invention in view of the above is to use mixing water when kneading and manufacturing concrete, and to wash the inside of the mixer for each batch by pressurizing the water measured from the water tank in the pressure tank. , The inside of the mixer and the inside of the concrete hopper are cleaned, and the air cylinder (4) attached to the outside of the mixer makes it possible to rotate the sprinkler pipe to clean the details of the ceiling and side walls. did.

Embodiment FIG. 1 is a perspective view showing an attached state of an embodiment of the present invention. Fig. 2 is a piping system diagram of this proposal.

According to the instruction of the mixer operation panel, 40 liters of water is measured from the water tank and fed into the pressure tank, and one second later, the pressurizing valve (11) is opened, and when the pressure reaches a predetermined 6K, the pressure switch (10 ) Is operated, the injection valve (13) is opened to inject pressure water, and after 2 seconds, the air cylinder (4) is operated for 5 seconds to rotate the sprinkler pipe (2). By rotating the sprinkler pipe (2), the cleaning range is expanded, and it is possible to clean the details such as the ceiling and side walls. After 6 seconds, the pressurizing valve (11) is closed, and after 3 seconds, the injection valve (13) is closed. After one second, the air vent valve (15) opens and the work is completed. By performing this operation in conjunction with the operation panel so that it is performed for each batch, the mortar component adhering to the inside of the mixer is washed before it is condensed, so that the details are clean. Further, if it is desired to wash the concrete hopper, it is possible by switching the solenoid valve (14) with a selector switch.
