Description

本発明は、破砕機の粉塵飛散防止用カバーに関する。更に詳しくは、破砕機から排出された破砕物をコンベアで搬送する方式の破砕機において、破砕機から排出された粉塵を周囲に飛散させないようにした破砕機の粉塵飛散防止用カバーに関する。   The present invention relates to a dust scattering prevention cover for a crusher. More specifically, the present invention relates to a dust scattering prevention cover for a crusher that prevents the dust discharged from the crusher from being scattered around in a crusher that conveys the crushed material discharged from the crusher by a conveyor.

岩石等の塊状物を破砕する破砕機は、高速で回転するロータ等で塊状物を破砕するため、そのブロア効果によって破砕機の排出口から粉塵が吹き出し、周囲に粉塵が飛散して環境に悪影響を与える。従来の破砕機は、破砕機の排出口近傍にダクトを接続し、ブロアでダクトを経由して粉塵を回収するようにしている。しかし、この集塵方法では、ブロアが必要なため設備費が高くなる不具合がある。   A crusher that crushes rocks and other massive objects crushes the massive objects with a rotor that rotates at high speed, so the blower effect blows out dust from the crusher's discharge port, and dust is scattered around and has an adverse effect on the environment give. In the conventional crusher, a duct is connected in the vicinity of the discharge port of the crusher, and dust is collected by the blower via the duct. However, this dust collection method has a problem that the equipment cost is high because a blower is required.

特許文献１に記載された破砕機の防塵カバーは、排出口から排出された破砕物を外部に搬送するコンベアに、コンベアの搬送路を覆う防塵カバーを設置し、防塵カバーに集塵ダクトを接続して粉塵を集塵機で回収するとともに、防塵カバー内に粉塵飛散防止用の水を噴射している。特許文献２に記載された破砕機の防塵装置は、排出口から排出された破砕物を外部に搬送するコンベアに、コンベアの搬送路を覆う防塵カバーを設置し、防塵カバーの開口部からファンで粉塵を吸入管に吸い込み、吸引された粉塵に噴射ノズルで水を噴射して湿潤させ、底に水が満たされた隔壁部に堆積した粉塵をコンベアに戻している。しかし、特許文献１、特許文献２に記載の破砕機の防塵手段は、集塵機やファン等が必要なため設備費が高くなる不具合がある。   The dustproof cover of the crusher described in Patent Document 1 is installed on the conveyor that conveys the crushed material discharged from the discharge port to the outside, and a dust collection duct is connected to the dustproof cover. The dust is collected by the dust collector, and water for preventing dust scattering is sprayed into the dust cover. The dustproof device of the crusher described in Patent Document 2 is provided with a dustproof cover that covers the conveyance path of the conveyor on a conveyor that conveys the crushed material discharged from the discharge port to the outside, and a fan is provided from the opening of the dustproof cover. Dust is sucked into the suction pipe, water is sprayed onto the sucked dust by a spray nozzle and wetted, and the dust deposited on the partition wall filled with water is returned to the conveyor. However, the dustproof means of the crusher described in Patent Literature 1 and Patent Literature 2 has a problem that the equipment cost is high because a dust collector and a fan are required.

本発明の目的は、構造が簡単で設備費が安価な破砕機の粉塵飛散防止用カバーを提供することにある。   An object of the present invention is to provide a dust scattering prevention cover for a crusher having a simple structure and a low equipment cost.

前記課題は以下の手段によって解決される。
即ち、本発明１の破砕機の粉塵飛散防止用カバーは、塊状物を破砕することにより生じた破砕物を排出口から排出する破砕機と、前記排出口から排出された破砕物を外部に搬送するコンベアと、前記コンベアの搬送路に沿って形成され、前記搬送路を覆う粉塵飛散防止用カバーであって、前記粉塵飛散防止用カバーには、前記コンベアの前記搬送路の途中に、前記コンベアの搬送方向に直交する方向の断面積が粉塵飛散防止用カバーの他の部位よりも広く形成された粉塵流速低減用カバー部が形成されていることを特徴とする。 The said subject is solved by the following means.
That is, the dust scattering prevention cover of the crusher according to the first aspect of the present invention includes a crusher that discharges crushed material generated by crushing a lump from a discharge port, and conveys the crushed material discharged from the discharge port to the outside. And a dust scattering prevention cover that is formed along a conveyance path of the conveyor and covers the conveyance path, wherein the dust scattering prevention cover includes the conveyor in the middle of the conveyance path of the conveyor. The dust flow velocity reduction cover portion is formed in which the cross-sectional area in the direction orthogonal to the conveying direction is wider than the other part of the dust scattering prevention cover.

本発明２の破砕機の粉塵飛散防止用カバーは、本発明１において、前記粉塵流速低減用カバー部は、前記コンベアの前記搬送路に沿って複数箇所に形成されていることを特徴とする。
本発明３の破砕機の粉塵飛散防止用カバーは、本発明１又は２において、前記粉塵流速低減用カバー部は、通気性の有る素材で形成されていることを特徴とする。
本発明４の破砕機の粉塵飛散防止用カバーは、本発明１又は２において、前記粉塵飛散防止用カバーには、その上端が前記粉塵飛散防止用カバーから吊り下げられるとともにその下端がコンベア上の破砕物に接触して、前記コンベア上の空間を間仕切りする柔軟な素材で形成されたカーテンが取り付けられていることを特徴とする。 The dust scattering prevention cover of the crusher of the present invention 2 is characterized in that, in the present invention 1, the dust flow velocity reduction cover part is formed at a plurality of locations along the transport path of the conveyor.
The dust scattering prevention cover of the crusher of the present invention 3 is characterized in that, in the present invention 1 or 2, the dust flow velocity reduction cover part is formed of a material having air permeability.
The dust scattering prevention cover of the crusher according to the fourth aspect of the present invention is the dust scattering prevention cover according to the first or second aspect, wherein the upper end of the dust scattering prevention cover is suspended from the dust scattering prevention cover and the lower end is on the conveyor. The curtain formed with the flexible raw material which contacts a crushed material and partitions the space on the said conveyor is characterized by the above-mentioned.

本発明の破砕機の粉塵飛散防止用カバーは、コンベアの搬送路の途中に断面積が広い粉塵流速低減用カバー部を形成して粉塵の流速を遅くして、コンベア上に粉塵を沈降し易くするため、粉塵の飛散が少なくて済み、構造が簡単で設備費が安価になる。   The dust scattering prevention cover of the crusher of the present invention forms a dust flow velocity reduction cover portion having a wide cross-sectional area in the middle of the conveyor conveyance path to slow down the dust flow rate and facilitate sedimentation of dust on the conveyor. Therefore, dust scattering is small, the structure is simple, and the equipment cost is low.

以下、本発明の第１の実施の形態を図面に基づいて説明する。図１は、本発明の第１の実施の形態の粉塵飛散防止用カバーを備えた破砕機を示す全体側面図、図２は図１のＰ部拡大縦断面図である。図１から図２に示すように、本発明の第１の実施の形態の粉塵飛散防止用カバーは竪型の破砕機に適用した例である。破砕機１は、破砕機１の上端の投入口１１から岩石等の塊状物である原料を投入し、図示しない高速で回転するロータで塊状物を破砕し、破砕機１の下端の排出口１２から破砕物と粉塵を同時に排出する。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a first embodiment of the invention will be described with reference to the drawings. FIG. 1 is an overall side view showing a crusher provided with a dust scattering prevention cover according to a first embodiment of the present invention, and FIG. 2 is an enlarged vertical sectional view of part P in FIG. As shown in FIGS. 1 to 2, the dust scattering prevention cover according to the first embodiment of the present invention is an example applied to a vertical crusher. The crusher 1 inputs a raw material that is a lump such as rock from an inlet 11 at the upper end of the crusher 1, crushes the lump with a rotor that rotates at a high speed (not shown), and a discharge port 12 at the lower end of the crusher 1. The crushed material and dust are discharged simultaneously.

排出口１２から排出された破砕物は、ベルト式のコンベア２上に落下し、コンベア２によって、図１の右側から左側に搬送されて、図示しない破砕物堆積場所に運ばれる。コンベア２には、搬送路を上部から覆う４個の粉塵飛散防止用カバー３１、３２、３３、３４が、コンベア２の搬送路に沿って、図１の右側から左側に向かって取り付けられている。図１の右端の粉塵飛散防止用カバー３１の上面には、破砕機１の下端の排出口１２が挿入される開口部が形成されている。この破砕機１の排出口１２から排出された破砕物は、コンベア２の右端上に落下する。また、同時に、排出口１２から排出された粉塵は、図１の右端の粉塵飛散防止用カバー３１内に流入して、図１の二番目の粉塵飛散防止用カバー（粉塵流速低減用カバー部）３２側に流れる。   The crushed material discharged from the discharge port 12 falls on the belt-type conveyor 2 and is conveyed by the conveyor 2 from the right side to the left side in FIG. Four dust scattering prevention covers 31, 32, 33, and 34 that cover the conveyance path from above are attached to the conveyor 2 along the conveyance path of the conveyor 2 from the right side to the left side in FIG. 1. . An opening for inserting the discharge port 12 at the lower end of the crusher 1 is formed on the upper surface of the dust scattering prevention cover 31 at the right end in FIG. The crushed material discharged from the discharge port 12 of the crusher 1 falls on the right end of the conveyor 2. At the same time, the dust discharged from the discharge port 12 flows into the dust scattering prevention cover 31 at the right end of FIG. 1, and the second dust scattering prevention cover (dust velocity reduction cover portion) of FIG. It flows to the 32 side.

粉塵飛散防止用カバー３１、３２、３３、３４は、コンベア２の搬送方向に直交する方向の断面積が異なって形成されている。すなわち、図１の二番目の粉塵飛散防止用カバー（粉塵流速低減用カバー部）３２は、図１の右端の粉塵飛散防止用カバー３１よりも、コンベア２の搬送方向に直交する方向の断面積が広く形成されている。また、図１の四番目の粉塵飛散防止用カバー（粉塵流速低減用カバー部）３４は、図１の三番目の粉塵飛散防止用カバー３３よりも、コンベア２の搬送方向に直交する方向の断面積が広く形成されている。   The dust scattering prevention covers 31, 32, 33, and 34 are formed with different cross-sectional areas in the direction orthogonal to the conveying direction of the conveyor 2. That is, the second dust scattering prevention cover (dust velocity reduction cover portion) 32 in FIG. 1 has a cross-sectional area in a direction perpendicular to the conveying direction of the conveyor 2 rather than the dust scattering prevention cover 31 at the right end in FIG. Is widely formed. Further, the fourth dust scattering prevention cover (dust flow velocity reduction cover portion) 34 in FIG. 1 is more disconnected than the third dust scattering prevention cover 33 in FIG. 1 in a direction perpendicular to the conveying direction of the conveyor 2. The area is wide.

従って、粉塵飛散防止用カバー（粉塵流速低減用カバー部）３２と粉塵飛散防止用カバー（粉塵流速低減用カバー部）３４に流入した粉塵は、その流速が低下する。その結果、粉塵飛散防止用カバー（粉塵流速低減用カバー部）３２と粉塵飛散防止用カバー（粉塵流速低減用カバー部）３４内での粉塵の滞留時間が長くなるため、粉塵はコンベア２上に沈降し易くなる。   Accordingly, the dust flowing into the dust scattering prevention cover (dust flow rate reduction cover portion) 32 and the dust scattering prevention cover (dust flow rate reduction cover portion) 34 has a reduced flow velocity. As a result, the dust staying time in the dust scattering prevention cover (dust flow velocity reduction cover portion) 32 and the dust scattering prevention cover (dust dust velocity reduction cover portion) 34 becomes longer, so that the dust stays on the conveyor 2. It becomes easy to settle.

図２に示すように、右端の粉塵飛散防止用カバー３１の上面内側には、カーテン４が吊り下げられ、カーテン４の下端が破砕物５に接触し、コンベア２上の空間を間仕切りしている。カーテン４は、ゴム等の柔軟な素材で形成されている。従って、カーテン４で粉塵の流れが妨げられるため、カーテン４を通過した粉塵の流速がさらに低下し、粉塵飛散防止用カバー（粉塵流速低減用カバー部）３２内での粉塵の滞留時間がさらに長くなるため、粉塵はコンベア２上に沈降し易くなる。   As shown in FIG. 2, the curtain 4 is suspended inside the upper surface of the dust scattering prevention cover 31 at the right end, the lower end of the curtain 4 contacts the crushed material 5, and partitions the space on the conveyor 2. . The curtain 4 is made of a flexible material such as rubber. Accordingly, since the flow of dust is hindered by the curtain 4, the flow rate of the dust that has passed through the curtain 4 is further reduced, and the residence time of the dust in the dust scattering prevention cover (dust flow rate reduction cover portion) 32 is further increased. Therefore, the dust easily settles on the conveyor 2.

次に、本発明の第２の実施の形態を図面に基づいて説明する。図３は、本発明の第２の実施の形態の粉塵飛散防止用カバーを備えた破砕機を示す一部を断面した全体側面図である。本発明の第２の実施の形態の粉塵飛散防止用カバーは第１の実施の形態の粉塵飛散防止用カバーの変形例であり、第１の実施の形態と同一部品には同一番号を付し、詳細な説明は省略する。図３に示すように、コンベア２には、搬送路を覆う４個の粉塵飛散防止用カバー３１、６２、３３、３４が、コンベア２の搬送路に沿って、図３の右側から左側に向かって取り付けられている。３個の粉塵飛散防止用カバー３１、３３、３４は、第１の実施の形態と同一形状であり、二番目の粉塵飛散防止用カバー６２だけが第１の実施の形態の粉塵飛散防止用カバー３２とは形状が異なる。   Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 3: is the whole sectional side view which shows a part which shows the crusher provided with the cover for dust scattering prevention of the 2nd Embodiment of this invention. The dust scattering prevention cover of the second embodiment of the present invention is a modification of the dust scattering prevention cover of the first embodiment, and the same parts as those in the first embodiment are denoted by the same reference numerals. Detailed description will be omitted. As shown in FIG. 3, the conveyor 2 has four dust scattering prevention covers 31, 62, 33, 34 covering the conveyance path from the right side to the left side in FIG. 3 along the conveyance path of the conveyor 2. Attached. The three dust scattering prevention covers 31, 33, and 34 have the same shape as the first embodiment, and only the second dust scattering prevention cover 62 is the dust scattering prevention cover of the first embodiment. 32 is different in shape.

すなわち、図３の二番目の粉塵飛散防止用カバー（粉塵流速低減用カバー部）６２は、第１の実施の形態の粉塵飛散防止用カバー（粉塵流速低減用カバー部）３２よりも、コンベア２の搬送方向に直交する方向の断面積が広く形成されている。また、右端の粉塵飛散防止用カバー３１の上面と二番目の粉塵飛散防止用カバー（粉塵流速低減用カバー部）６２の右側面上部をホース６１で接続し、右端の粉塵飛散防止用カバー３１内の粉塵を二番目の粉塵飛散防止用カバー（粉塵流速低減用カバー部）６２の上部に噴出させている。ホース６１の噴出角度θ１は、コンベア２の傾斜角度θ２よりも大きく形成されている。   That is, the second dust scattering prevention cover (dust flow rate reduction cover portion) 62 in FIG. 3 is more conveyor 2 than the dust scattering prevention cover (dust flow rate reduction cover portion) 32 of the first embodiment. The cross-sectional area in the direction orthogonal to the conveying direction is formed widely. Further, the upper surface of the dust scattering prevention cover 31 at the right end and the upper right side of the second dust scattering prevention cover (dust dust flow reduction cover portion) 62 are connected by a hose 61, and the dust scattering prevention cover 31 at the right end is connected. Is sprayed onto the upper portion of the second dust scattering prevention cover (dust flow velocity reduction cover portion) 62. The ejection angle θ1 of the hose 61 is formed larger than the inclination angle θ2 of the conveyor 2.

従って、ホース６１から粉塵飛散防止用カバー（粉塵流速低減用カバー部）６２に流入した粉塵は、ホース６１から上方に噴出するため、粉塵の重力によってコンベア２上に落下し易くなる。また、粉塵飛散防止用カバー（粉塵流速低減用カバー部）６２の断面積が広くなることによって粉塵の流速が低下するため、粉塵飛散防止用カバー（粉塵流速低減用カバー部）６２内での粉塵の滞留時間が長くなるため、粉塵はコンベア２上に沈降し易くなる。四番目の粉塵飛散防止用カバー（粉塵流速低減用カバー部）３４内でも、第１の実施の形態と同様に、粉塵の滞留時間が長くなるため、粉塵はコンベア２上に沈降し易くなる。なお、ホース６１の先端に通気性のある袋を取り付けて、シルト、粘土、雲母等の微細物質はコンベア２上に戻すことなく、これを回収しても良い。   Accordingly, the dust flowing into the dust scattering prevention cover (dust flow rate reduction cover portion) 62 from the hose 61 is ejected upward from the hose 61, so that it easily falls onto the conveyor 2 due to the gravity of the dust. Further, since the dust flow velocity is reduced by increasing the cross-sectional area of the dust scattering prevention cover (dust flow velocity reduction cover portion) 62, the dust scattering prevention cover (dust velocity reduction cover portion) 62 Therefore, the dust tends to settle on the conveyor 2. Even in the fourth dust scattering prevention cover (dust flow rate reduction cover portion) 34, the dust stays longer in the same manner as in the first embodiment, so that the dust easily settles on the conveyor 2. Note that a breathable bag may be attached to the tip of the hose 61, and fine substances such as silt, clay, mica, etc. may be collected without returning to the conveyor 2.

次に、本発明の第３の実施の形態を図面に基づいて説明する。図４は、本発明の第３の実施の形態の粉塵飛散防止用カバーを備えた破砕機を示す全体側面図である。本発明の第３の実施の形態の粉塵飛散防止用カバーは第１の実施の形態の粉塵飛散防止用カバーの変形例であり、第１の実施の形態と同一部品には同一番号を付し、詳細な説明は省略する。図４に示すように、コンベア２には、搬送路を覆う４個の粉塵飛散防止用カバー３１、７２、３３、３４が、コンベア２の搬送路に沿って、図４の右側から左側に向かって取り付けられている。３個の粉塵飛散防止用カバー３１、３３、３４は、第１の実施の形態と同一形状であり、二番目の粉塵飛散防止用カバー７２だけが第１の実施の形態の粉塵飛散防止用カバー３２とは形状が異なる。   Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 4 is an overall side view showing a crusher provided with a dust scattering prevention cover according to a third embodiment of the present invention. The dust scattering prevention cover of the third embodiment of the present invention is a modification of the dust scattering prevention cover of the first embodiment, and the same parts as those in the first embodiment are denoted by the same reference numerals. Detailed description will be omitted. As shown in FIG. 4, the conveyor 2 has four dust scattering prevention covers 31, 72, 33, and 34 covering the conveyance path from the right side to the left side in FIG. 4 along the conveyance path of the conveyor 2. Attached. The three dust scattering prevention covers 31, 33, 34 have the same shape as the first embodiment, and only the second dust scattering prevention cover 72 is the dust scattering prevention cover of the first embodiment. 32 is different in shape.

すなわち、図４の二番目の粉塵飛散防止用カバー（粉塵流速低減用カバー部）７２は、図４の右端の粉塵飛散防止用カバー３１よりも、コンベア２の搬送方向に直交する方向の断面積が広く形成されている。また、二番目の粉塵飛散防止用カバー（粉塵流速低減用カバー部）７２は、布等の通気性の有る素材で形成されている。   That is, the second dust scattering prevention cover (dust dust flow reduction cover portion) 72 in FIG. 4 has a cross-sectional area perpendicular to the conveying direction of the conveyor 2 rather than the dust scattering prevention cover 31 at the right end in FIG. Is widely formed. The second dust scattering prevention cover (dust flow rate reduction cover portion) 72 is formed of a breathable material such as cloth.

従って、粉塵飛散防止用カバー（粉塵流速低減用カバー部）７２に流入した粉塵は、布等の隙間から空気が外部に抜け出すため、粉塵の流速が遅くなり、かつ、布等で粉塵が濾過されるため、粉塵の重力によってコンベア２上に落下し易くなる。また、粉塵飛散防止用カバー（粉塵流速低減用カバー部）７２の断面積が広くなることによって粉塵の流速が低下するため、粉塵飛散防止用カバー（粉塵流速低減用カバー部）７２内での粉塵の滞留時間が長くなるため、粉塵はコンベア２上に沈降し易くなる。四番目の粉塵飛散防止用カバー（粉塵流速低減用カバー部）３４内でも、第１の実施の形態と同様に、粉塵の滞留時間が長くなるため、粉塵はコンベア２上に沈降し易くなる。   Accordingly, the dust that has flowed into the dust scattering prevention cover (dust flow rate reduction cover part) 72 is discharged from the gaps of the cloth, etc., so that the dust flow rate is slow and the dust is filtered by the cloth. Therefore, it becomes easy to fall on the conveyor 2 by the gravity of dust. Further, since the dust flow velocity is reduced by increasing the cross-sectional area of the dust scattering prevention cover (dust flow velocity reduction cover portion) 72, the dust scattering prevention cover (dust velocity reduction cover portion) 72 Therefore, the dust tends to settle on the conveyor 2. Even in the fourth dust scattering prevention cover (dust flow rate reduction cover portion) 34, the dust stays longer in the same manner as in the first embodiment, so that the dust easily settles on the conveyor 2.

本発明の実施の形態では、コンベアの搬送路の途中に断面積が広い粉塵流速低減用カバー部を形成して粉塵の流速を遅くして、コンベア上に粉塵を沈降し易くするため、粉塵の飛散が少なくて済み、構造が簡単で設備費が安価になる。   In the embodiment of the present invention, a dust flow velocity reduction cover portion having a wide cross-sectional area is formed in the middle of the conveyance path of the conveyor to reduce the dust flow velocity and to easily settle the dust on the conveyor. Less scattering is required, the structure is simple, and the equipment cost is low.

以上、本発明の実施例を説明したが、本発明はこの実施例に限定されることはない。例えば、前述した実施の形態では、コンベアの搬送路に２個の粉塵流速低減用カバー部を形成した例について説明したが、粉塵流速低減用カバー部は１個または２個以上形成してもよい。また、前述した実施の形態では、コンベア上の空間を間仕切りする柔軟な素材のカーテンを１個取り付けた例について説明したが、複数個取り付けてもよい。さらに、前述した実施の形態では、粉塵流速低減用カバー部全体を通気性の有る素材で形成した例について説明したが、粉塵流速低減用カバー部の一部を通気性の有る素材で形成してもよい。また、前述した実施の形態では、粉塵を全てコンベア上に戻しているが、別の排出口も設けて分離したものでもよいる。   As mentioned above, although the Example of this invention was described, this invention is not limited to this Example. For example, in the above-described embodiment, an example in which two dust flow rate reduction cover portions are formed on the conveyance path of the conveyor has been described. However, one or more dust flow rate reduction cover portions may be formed. . In the above-described embodiment, the example in which one flexible material curtain for partitioning the space on the conveyor is described, but a plurality of curtains may be attached. Furthermore, in the embodiment described above, an example in which the entire dust flow rate reduction cover part is formed of a breathable material has been described. However, a part of the dust flow rate reduction cover part is formed of a breathable material. Also good. In the above-described embodiment, all the dust is returned to the conveyor. However, another dust outlet may be provided and separated.
