Description

MISER WITH CLEANING DEVICE
The invention relates to a device for mixing pasty and liquid masses.
Such devices are much used for mixing paint or inks, for instance for printing companies. The inks are for instance placed together in measured quantities in a container and these inks are subsequently mixed by means of a mixer to form a homogeneous substance. This ink can then be used to print an object. When ink must be mixed in a following container, the mixer first has to be cleaned so as to prevent contamination from the preceding container.
Cleaning devices are known wherein the mixer is taken out of the container, is then displaced or rotated in a horizontal plane, whereafter the mixer is carried into a washing space and there cleaned by means of a cleaning liquid.
Such a cleaning device has the drawback that it takes up a great deal of space and that the movement of the mixer takes up much time, whereby the throughput speed of such a mixing device is low.
It is an object of the invention to provide a mixing device wherein cleaning can be performed more rapidly and wherein in addition little space is taken up by the mixing device . This objective is achieved according to the invention with a device for mixing pasty and liquid masses, which device comprises:
- a substantially vertically displaceable mixer having a substantially vertical, driven shaft and a mixer part arranged on an outer end of the shaft, and - a cleaning device for cleaning at least the mixer part, which cleaning device comprises a washing space arranged around the vertical shaft and bounded by walls, wherein spray means are arranged in the washing space and an access opening is arranged in a lower wall such that at least the mixer part can be carried into the washing space. So as to achieve an even better cleaning, a second scraper can be arranged so that a double scraper ring results. Further water rinsing can moreover then be arranged wherein a water flow passes along the shaft between the two scrapers .
A space-saving is firstly already achieved by placing the washing space above the mixing device instead of adjacently thereof. In addition, a horizontal displacement of the mixer is prevented, whereby a higher throughput speed is obtained. Because the mixer must be taken out of the container, the mixer must be displaced in vertical direction at all times. By now placing the washing device in the same line as the direction of removal, i.e. above the container, the mixer can be carried in one movement out of the container into the washing space.
In a preferred embodiment of the device according to the invention, the access opening comprises a standing edge. This prevents for instance cleaning liquid flowing out on the underside via the access opening and possibly falling into a container placed thereunder.
In a further embodiment the device comprises a closure for closing an access opening. This prevents any cleaning agent or residue from the mixer dripping out via the access opening in the lower wall.
In another embodiment of the device according to the invention, a passage is arranged in an upper wall of the upper space for passage of the shaft, and a scraper is arranged in the passage for scraping the shaft clean. Adhering dirt is kept inside the washing space with this scraper and there flushed away.
In yet another embodiment of the device according to the invention, the washing space is displaceable in vertical direction. If the mixing device is used for containers of different dimensions, it may be advantageous to always place the washing space at a minimal distance above the containers. A maximum throughput speed is hereby achieved.
These and other features of the invention are further elucidated with reference to the annexed drawings .
Figure 1 shows in perspective view with partly broken-away parts an embodiment of the device according to the invention.
Figure 2 shows the device of figure 1 in a position where the mixer has been placed in the washing space . Figure 3 shows an enlarged view of the washing space in perspective and with partly broken-away parts.
Figure 1 shows a device 1 according to the invention. This device 1 has a rear wall 2 on which are mounted guides 3 on which a bearing block 4 is guided. This bearing block 4 can be displaced in vertical direction by means of a pneumatic cylinder 5. Arranged on this bearing block 4 is a motor 6 which drives a shaft 7, on the outer end of which is arranged a mixer part 8. Mixer 8 protrudes into a container 9 which is supplied by means of conveyor belt 10. Shaft 7 of the mixer protrudes through a washing space 11.
Figure 2 shows the position in which the bearing block 4 is carried vertically upward along guides 3, whereby shaft 7 with mixer part 8 thereon is likewise carried upward. Mixer part 8 is hereby carried into washing space 11. The mixer part has herein passed through the opening 12 in the underside of washing space
11. Opening 12 has a standing edge 13, thus preventing liquid being able to flow via opening 12 into container
9.
Figure 3 shows washing space 11 in more detail. Opening 12 is here closed by a closing slide 14.
This is operated by means of a rod assembly 14 and a cylinder 16. Arranged in washing space 11 are sprayers
17 which clean mixer part 8. Cleaning liquid can then flow away via outlet 18.
Shaft 7 protrudes to the outside on the top side of the washing space 11 and is therein enclosed by a scraper ring 19. This scraper ring 19 scrapes dirt from shaft 7 so that the dirt remains behind in washing space 11 and can there be drained off .
