Description
Technical Field
[0001] The utility model relates to the technical field of blasting dust reduction, in particular to a water bag plugging dust reduction device for open-pit mine blasting dust. Background Technique
[0002] At present, in open-pit mine blasting operations, in order to reduce the harm caused by the dust generated during blasting to the surrounding environment and the health of personnel, a water bag plugging device is usually used to control dust. As an important dust reduction device, the fixing method of the water bag plays a crucial role in the stability and effect of the device. However, there are some disadvantages in the current water bag fixing method, mainly manifested as cumbersome fixing steps, complex installation, low operability, etc., resulting in less than ideal efficiency and convenience of using the water bag plugging device. And after blasting, the debris of the water bag will fly everywhere, which is easy to pollute the environment. Content of the Utility Model
[0003] The purpose of the utility model is to provide a water bag plugging dust reduction device for open-pit mine blasting dust, so as to solve the problems put forward in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A water bag plugging dust reduction device for open-pit mine blasting dust, including an outer bag, a rope box and a rope. One end of the outside of the outer bag is provided with a connecting pipe, one end of the connecting pipe is connected with an inner bag, and the inner bag is arranged in the middle of the inside of the outer bag. A winding rod is arranged in the middle of the rear surface of the outside of the outer bag, and a rope box is arranged in the middle of the front surface of the outside of the outer bag. A shaft rod is rotatably installed inside the rope box, and a rope is wound around the surface of the shaft rod.
[0005] When using a water bag plugging dust reduction device for open-pit mine blasting dust in the technical solution of the present utility model, the user carries the utility model to the object to be blasted, and after placing it on its surface, the staff rotates the clamping rod. After the clamping rod rotates, the limit on the baffle is released. At this time, the staff rotates the baffle again, pulls out the rope wound inside from the rope box, walks the rope around the surface of the object to be blasted and then winds it around the surface of the winding rod. After winding, hook the hook connected to one end of the rope onto the hanging rod installed in the groove opened on the surface of the rope, and hang it on the hanging rod at the tightest part of the rope, so as to fix the outer bag on the surface of the object to be blasted. After fixing, the staff takes the water pipe and connects it to one end of the connecting pipe. After connecting, open the valve and use the water pipe to fill the inner bag installed in the outer bag with water. After filling, the staff turns the valve to close the connecting pipe to prevent the water in the inner bag from flowing back. Then the staff disconnects the water pipe from the connecting pipe. After all preparations are completed, the staff can blast the object to be blasted. During blasting, the inner bag and the outer bag made of low-density polyethylene material will be burned out by the flame ignited by the explosion, and the water in the inner bag will be raised during the explosion to reduce the dust generated by the explosion.
[0006] Preferably, one end of the rope is connected with a hook. By arranging the rope, the outer bag can be fixed on the object to be blasted, achieving the effect of surrounding and fixing.
[0007] Preferably, a groove is formed on the surface of the rope, and a hanging rod is arranged inside the groove. Through the cooperation of the hook and the hanging rod, the rope can be hooked at the tightest place after passing around the surface of the winding rod, achieving the effect that the rope can be adapted and fastened according to the size of the object to be blasted.
[0008] Preferably, a baffle is rotatably installed on the front surface of the outer part of the rope box through a hinge, and a clamping rod is arranged at the top of the baffle. The arrangement of the clamping rod enables the baffle to be fixedly closed, while the installation of the baffle enables the rope box to be opened, facilitating the staff to take out the rope placed inside the rope box.
[0009] Preferably, a valve is fixed on the middle surface of the communicating pipe, and the other end of the communicating pipe is connected with a water pipe. Through the cooperation of the valve and the water pipe, water for dust reduction can be switched on and filled inside the inner bag, achieving the effect of switching and filling water.
[0010] Preferably, both the outer bag and the inner bag are made of low-density polyethylene material. The outer bag and the inner bag made of low-density polyethylene material have the advantages of being easy to burn and having good compressive resistance. During installation and movement, they can resist abrasion and prevent damage, while being easy to burn during blasting and not generating excessive debris to cause environmental pollution.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. The present utility model installs a rope box for hiding and placing the rope on one side of the outer bag. When the outer bag is placed on the object to be blasted, the rope can be taken out from the rope box, then wound around the object for one circle, passed around the surface of the winding rod, and finally hooked on the hanging rod by using the hook, thereby fixing the outer bag on the object. Its fixing operation is simple and convenient for the staff to use. Moreover, both the outer bag and the inner bag are made of low-density polyethylene material, which is easy to burn during blasting, reduces the generation of debris, and improves the environmental protection effect.
