Description

  The present invention relates to a paint adhering material cleaning apparatus installed at or near a construction site in order to clean equipment and tools to which paint is applied in painting work.

  In painting and renovation work for buildings and structures, it is important to take measures against drainage and wastewater generated by cleaning paints adhering to equipment and tools used on site. Safe processing becomes a problem. The safe treatment here means that the water pollution and soil pollution regulations stipulated in the Basic Environmental Law should be satisfied, the Water Pollution Control Law, the Waste Management Law, the Lake Law, and the Soil Contamination Countermeasures Law. It means treatment that satisfies various regulations stipulated by the Sewerage and Septic Tank Law and local governments.

  The paints currently used for painting work are mainly water-based paints (water-based paints), and the wastewater generated by the washing is water-soluble synthetic resin blend paint, synthetic resin emulsion paint, thin finish material, multi-layer finish material, floor It is generated by processing coating materials, water-based rust-preventing paints, sealers, and base preparation coating materials. For example, in construction using water-based paints and water-based mortar materials, cleaning wastewater for tools and tools used for painting such as brushes and rollers is either sent to industrial exhaust treatment or separated and agglomerated using water tanks, etc. Was discarded above. However, there has been a problem that untreated cleaning wastewater flows as sewage due to human error. In addition, if washing wastewater flows into a rainwater basin and spreads into nearby rivers, it may be a violation of the Industrial Waste Management Law or the Water Pollution Control Law. In order to avoid such a situation, it was necessary to install a large sedimentation tank, combine existing products, and further thorough processing by education and guidance of those engaged in the work.

  On the other hand, the prior art includes, for example, a waste liquid treatment system found in Japanese Patent Application Laid-Open No. 2005-211182. The above invention is referred to as a clean water treatment system for polluted waste liquid containing water-based paint, and is shown as an on-vehicle transport type that is transported by being mounted on a truck, a wagon, etc., but a power device such as a stirring motor or pump It is a large-scale equipment equipped with a power supply or fuel. Therefore, it is not suitable for relatively small-scale applications, such as carrying it to the construction site and cleaning it as needed by the person engaged in the work. In addition, there is a situation in which it is difficult to obtain even a space for parking a vehicle as described above in a work place where there is a limit to a site that can be used like a condominium in the city center. Therefore, it is considered necessary to establish a temporary system dedicated to cleaning in order to prevent human error and realize proper wastewater treatment even in a narrow space.

To do. In the case of the apparatus 10 according to the present invention, it is possible to implement both the form without the sink 12 and the form with the sink 12. Washing wastewater generated by washing the instruments and tools with the sink 12 is stored. If the sink 12 is not provided, the cleaning wastewater thrown directly into the storage tank 14 is stored. In any case, it is assumed that the storage tank 14 has a capacity that can store a considerable amount of washing waste water. For example, if the storage tank 14 has a capacity of about 40 liters, it is possible to store an amount of waste water generated by washing at least several times or about ten times.

  The storage tank 14 is installed in the lower part of the sink 12 and slightly in the upper part of the apparatus as a whole, and the lower part of the storage tank 14 serves as a collection bag disposing space 22 for a movable receiving tank 21 described later. Yes. In each figure, 15 is a faucet, 16 is a place for chemicals such as a neutralizing agent and a flocculant, and equipment such as a PH meter. The faucet 15 is located at the left hand of the rear part of the sink and the place 16 is also placed on the right hand. Has been. On the bottom surface of the sink 12, a washing net 17 for cleaning a tool or tools to which water-based paint or other dirt is attached is disposed so as to cover the opening 13 (see FIGS. 1 and 2).

  As the washing net 17, a sheet-like member such as an expanded metal product having an uneven surface is suitable so that paints adhered by rubbing tools such as a brush and a roller can be washed off. The illustrated washing net 17 has a shape slightly smaller than the inner dimension of the sink 12 and is detachable so as to be placed on the bottom surface of the sink 12 and fixed by the inner wall. However, the rectangular side may be hinged to the bottom surface of the sink, etc., and may be used by being tilted to the bottom surface or standing up as necessary.

  The storage tank 14 has a drain port 19 provided with an opening / closing part 18 for storing or discharging cleaning wastewater at the bottom.

A bag collection 20 is provided. The collection bag 20 is preferably a bag-shaped bag made of a material having an opening (mesh) suitable for the purpose of collection of the agglomerated processed product and outflow of moisture. As a bag-like material satisfying this purpose, those used as sandbags are suitable. For example, fabric products made of synthetic fibers such as polyethylene, or fabric products manufactured by knitting fibers such as hemp bags that have been mainstream in the past. Is preferred.

  The device 10 of the present invention also uses a movable receiving tank 21 in combination so that the cleaning waste water discharged by placing the collection bag 20 can be collected and discharged. The illustrated movable receiving tank 21 has a container structure formed in a substantially box shape (see FIGS. 4 and 5), and is provided with a caster wheel of a moving means 23 on a lower surface via a leg piece 21a. The type receiving tank 21 is arranged in the collection bag arranging space 22 and the collection bag 20 is moved from the space 22 to the outside of the apparatus main body 11. A handle 21b is used as a handle when the collection bag 20 is moved. In addition, the leg piece 21a has the objective of obtaining the flow of the waste_water | drain toward the drain port 21c side while ensuring the height difference of the drain port 21c and a grounding surface.

  The movable receiving tank 21 appropriately collects the agglomerated processed product by placing the collection bag 20 and causes the moisture to flow out, so that the placed collection bag 20 is not submerged. The filter plate 24 is used in combination so that the washing wastewater can penetrate into the gravity. The filter plate 24 has a strength to receive the load of the collection bag 20 and retain a flat shape in order to prevent the washing wastewater received in the collection bag 20 from being submerged, and a slat structure that allows the water to flow out. It is important to have (see FIG. 6). For this reason, the filter plate 24 has a shallow dish-like structure, and a large number of horizontally-slit water passage holes 24a are formed on almost the entire bottom surface thereof. In addition, 24b is provided in the front and back of the filter plate 24 as a long hole for a handle, and 24c shows a notch for adjusting the amount of water, but when drainage is emphasized mainly when handling a water-based paint. Suitable for However, the notch 24c is unnecessary for the purpose of damming fine components when handling, for example, a cement-based substance. Therefore, the notch 24c is provided only on one of the front and rear sides, and the front and rear direction is changed as necessary. Can be used properly.

  Further, according to the present invention, the apparatus main body 11 is provided with leg pillars 25 at the four corners, thereby providing a space 22 for collecting bag placement at the lower part, and a leg height adjusting mechanism at the lower end of each leg pillar 25. 26 is provided.

  The movable receiving tank 21 is provided with a drain port 21c at the rear (see FIG. 7), and a drain duct 21d is connected to the drain port 21c. In each figure, 27 is a cleaning gun receiving portion, 28 is a lateral frame, and a pair is provided on both the left and right sides, 29 is a rear lateral frame, and therefore there is no frame only on the front side. It becomes the taking in / out part of the expression receiving tank 21.

  The paint adhering matter cleaning apparatus 10 according to the present invention configured as described above is very small, and is particularly suitable for installation in a narrow space such as a condominium in a downtown area. In other words, craftsmen engaged in painting work use it to wash paints, water paints such as brushes, rollers, containers, etc. or other instruments that are attached with dirt. In the example, the washing net 17 is set in the sink 12, and the water washing 15 is opened and washed with running water. And the washing net | network 17 is removed after washing | cleaning. If the washing water accumulated in the storage tank 14 has reached a certain level that can be perceived as a limit by experience, first, the pH of the washing wastewater is measured using a PH meter, and the storage of equipment The neutralizing agent is taken out from No. 16, and an appropriate amount is added according to the PH value, and the neutralization treatment is performed so that the washing wastewater is within the range of PH5-9. Next, a flocculant is added to the neutralized washing wastewater, and the faucet 15 is opened to cause a water flow, or the washing wastewater is stirred manually to separate paint components and the like (separation by aggregation). After visually confirming the separation, the drainage lid 18a of the opening / closing part 18 is removed, and the secondary washing wastewater after separating the paint is discharged to the drainage trap 19a. Here, although not shown, it is also possible to set a basket for filtration in the drain trap 19a, collect the separated agglomerate together with the basket-like main body, collect it, and discard it.

The secondary cleaning wastewater that has passed through the drain trap 19a flows into the collection bag 20 from the inlet 20a through the downward nozzle 19b (see FIG. 7). Since the collection bag 20 is placed on the metal filter plate 24, the opening of the collection bag 20 is not clogged or spread, and the gravity penetration is not hindered. The collection bag 20 is not submerged, and only water can be smoothly drained (separation by filtration). In this way
First treatment: Separation and filtration by coagulation / fixation of the flocculant in the storage tank 14 and adjustment processing of hydrogen ion concentration for the secondary washing waste water,
Second treatment: Filtration treatment of mainly mortar substances by filtration using a fine-grained filtration basket,
Third processing: Flock removal processing separated by the opening of the collection bag 20,
Is done.
After that, the floc or the mixture of floc and mortar material is gradually filled and collected in the collection bag 20, and when the collection amount of the collection bag 20 reaches a certain level, the inflow of the secondary washing wastewater is stopped and the injection port 20a is closed, the collection bag 20 is pulled out of the apparatus together with the movable receiving tank 21, and the collection bag 20 is stored for the next processing step. Since the collection bag 20 can be drained by stacking and placing it (see FIG. 8), it is convenient for disposal. The collected material can be recycled as waste plastic or cement material in addition to disposal as industrial waste after aeration. The cleaning device 10 of the present invention is suitable for processing a relatively small amount of cleaning wastewater at a work place where usable space is limited, such as an apartment renovation work. However, it can be used not only for repair work and repair work for buildings, but also for new construction work, and it is clear that it has the expected effect.
