本考案は鋼板の表面をシヨツトブラストする際
に鋼板の表面に堆積した研掃材を効率よく除去す
るクリーナー装置に関する。[Detailed Description of the Invention] The present invention relates to a cleaner device that efficiently removes abrasive material deposited on the surface of a steel plate when the surface of the steel plate is shot blasted.
従来、この種のクリーナー装置は種々開発され
ており、スクレーパタイプのもの、空気ノズル式
のものあるいはエアーカーテン式のものなどが知
られているが、いづれのものも耐久性、除去効率
性等を充分に満足するものではなかつた。 Various types of cleaner devices of this type have been developed in the past, including scraper type, air nozzle type, and air curtain type. It wasn't completely satisfying.
すなわち、スクレーパタイプのものは、例えば
第1図及び第2図に示す如きものであり、鋼板1

ゴム板等が使用されているが、このゴム板4が鋼
板1の摺動により摩耗するため、頻繁にゴム板を
交換する必要があつた。そして、この交換作業に
多大な労力と時間を要するという欠点があつた。 That is, the scraper type is, for example, as shown in FIGS.
By bringing the scraper 2 shaped like an inverted "dog" into contact with the surface of the steel plate 1 and moving the steel plate 1 in the direction of arrow A in the figure, the shot 3, which is an abrasive material, is moved to both ends of the steel plate 1. Then, the steel plate 1 is made to fall from above. A rubber plate or the like is normally used for the shoe part 4 provided on the lower surface of the scraper 2 that is in contact with the surface of the steel plate 1 in order to improve the adhesion with the steel plate 1. The rubber plate had to be replaced frequently because it wore out due to sliding. Another disadvantage is that this replacement work requires a great deal of effort and time.
一方、空気ノズル式のものは、例えば第3図及

ルの間のシヨツトを充分に吹き飛ばすことができ
ず、シヨツトの除去率が悪くなる。そこで、送出
する空気量を増加せしめると多大の駆動力を必要
とし、機器に必要以上の負荷がかかるばかりでな
く、消費するエネルギーも多大になつてしまう。 On the other hand, the air nozzle type is as shown in FIGS. 3 and 4, for example, and has two parallel air headers 5,
5', and the air headers 5, 5' are provided with a large number of nozzles 6, which are inclined toward the left and right side edges of the steel plate, respectively.
6..., 6', 6'... are arranged, and a blower (not shown) is installed.
Air is sent to the air headers 5, 5' from the hoses 7, 7' connected to the nozzles 6, 6,...6',
The air stream B is injected obliquely downward onto the surface of the steel plate 1 from 6', and the shots 3 are blown away.
If the layer of shots 3 on the steel plate 1 is as thin as several mm, the nozzles 6, 6..., 6',
Not only the shots on the extension line of the nozzles 6', but also the shots 3 between the nozzles can be cleaned relatively easily. However, the shot 3 layer
In the case of a thick layer of 10 to 30 mm or more, the shot between the nozzles cannot be blown away sufficiently, resulting in a poor shot removal rate. Therefore, if the amount of air to be sent out is increased, a large amount of driving force is required, which not only places an unnecessary load on the equipment but also consumes a large amount of energy.

搬送機を組み込まなくてはならず、設計上の困難
性を強い、コスト高となる欠点があつた。 The air curtain type is, for example, as shown in FIGS. 5 and 6, in which a long nozzle 8 with a narrow slit-like opening is attached to an air header 9, and the surface of the steel plate 1 is sprayed from the nozzle 8. Air is injected diagonally from above, and the air header 9
A hood 10 having an opening 10a formed on the side of the air header 9 is provided in parallel on the right side of the hood 10, and the shot 3 is blown away by the air flow B injected from the nozzle 8 and received in the hood 10. A conveying member 11 made of a screw conveyor or the like is provided within this hood 10.
As a result, the shot 3 is carried out of the surface of the steel plate 1. This method is practical when the layer of shots 3 on the steel plate 1 has a certain thickness, but as the layer of shots 3 becomes thicker, the angle at which the shots 3 are blown off increases as shown by the arrow in Figure 7. is tilted upward to a greater extent than the horizontal, while when it becomes thinner, it becomes a small angle close to the horizontal as shown by the arrow in FIG. Therefore, the direction in which the shot is blown varies greatly depending on the thickness of the layer of the shot, and as a result, it is difficult to uniformly feed the shot 3 into the hood 10, and the thickness of the layer of the shot 3 does not change. In some cases, efficient removal is not possible. In addition, the shot conveyor must be built into a narrow shot blasting machine, making the design difficult and increasing costs.

In this device, a header is provided at an angle with respect to the width of the steel sheet, and a nozzle with a slit-shaped opening is provided in the header diagonally downward toward the surface of the steel sheet. It is characterized by the provision of a number of direction control plates that guide the jet toward the target.

..., 24', 24'..., the direction is determined by It is possible to blow it off from above. Also, during this injection, the air flow B is sent out from the slit-shaped opening, so there is no unevenness in the air flow, and it collides uniformly with the shots 3 on the steel plate 1, making it possible to blow off the shots 3 uniformly. Efficient removal of abrasive materials such as shot 3 becomes possible.
上記した各角度θ1,θ2及びθ3は研掃材の材質、
粒度あるいは空気流の密度や速度等によつて、
種々変更が可能であるが、概ね、以下のように定
められる。 The above angles θ 1 , θ 2 and θ 3 are determined by the material of the abrasive material,
Depending on the particle size or the density and speed of the air flow,
Although various changes are possible, they are generally defined as follows.

ように、吹き飛ばされるシヨツトが残存するシヨ
ツトと接する長さsが長くなつて、摩擦抵抗が増
大して好ましくない。そこで、30度〜60度が実用
的であり、特に45度が好適である。 In other words, if the angle θ 1 that the nozzles 23, 23' make with the horizontal surface of the steel plate 1 is too large, the angle of the airflow that is blown onto the steel plate 1 and reflected will also become large, making it possible to blow the shot high upwards. However, because the flight distance is small, the shot cannot be blown outward in the width direction of the steel plate, and on the other hand, if it is too small, the force that pushes the shot away in the direction opposite to the direction of movement of the steel plate 1 (arrow A) increases. However, the force that blows it upwards decreases. Therefore, an appropriate angle is determined taking these into consideration, but a range of 30 degrees to 60 degrees is preferred, with 45 degrees being particularly preferred. Also, the angle θ 2 that the headers 21, 21' make with the width of the steel plate 1 is
The relationship between the length l and the width B of the steel plate 1, lcosθ 2 =
It is determined by the correlation between l set by B/2 and the component force in the width direction of the air flow due to the angle θ 2 .
The range where the length l is small is good. Specifically, 10 degrees to 30 degrees, particularly around 20 degrees is suitable. Furthermore, if the angle θ 3 that the direction control plate 24 makes with the header 21 is too large, the component force in the width direction of the obtained steel plate 1 will become small, which is undesirable. As shown in FIG. 13, the contact length s of the blown shot with the remaining shot becomes longer, which is undesirable because frictional resistance increases. Therefore, 30 degrees to 60 degrees is practical, and 45 degrees is particularly suitable.
以上のようにして角度θ1,θ2及びθ3が適宜選択

う実用上の効果を有する。 In this embodiment, in which the angles θ 1 , θ 2 and θ 3 are appropriately selected as described above, it is possible to blow off the abrasive material efficiently and evenly in the width direction of the steel plate 1, and remove the abrasive material. Efficiency increases dramatically, making it possible to reduce operating power by half. Furthermore, since the entire device is simple, it can be provided at low cost, has few breakdowns, and has practical effects such as easy maintenance and management.
