Abstract
Description
Technical Field
[0001] This utility model relates to the field of open-pit mine dust suppression technology, and more specifically, to a dust suppression device for open-pit mine blasting. Background Technology
[0002] Dust generated during the loading and unloading process in open-pit mines is produced by electric shovels, resulting in large dust volumes and severe pollution. As one of the main sources of dust pollution in open-pit mines, the loading and unloading process is a continuous semi-fixed dust-generating point, and the dust it produces has not been effectively controlled.
[0003] In existing technologies, water spraying is commonly used to reduce dust generation during the loading and unloading processes of open-pit mines. However, water spraying cannot effectively wet the interior of the open-pit mine blast pile. Most of the dust suppressant flows downwards along the working face and shallow blasting cracks, making it difficult for the dust suppressant to penetrate deep into the blast pile. Therefore, the existing water spraying dust suppression method is ineffective, and the dust suppressant is not effectively utilized.
[0004] There is currently no effective solution to the above problems. Utility Model Content
[0005] The main objective of this invention is to provide a dust suppression device for explosive piles, in order to solve the problem that dust suppressants are not effectively utilized in the prior art.
[0006] To achieve the above objectives, according to one aspect of the present invention, a dust suppression device for explosive pile-up is provided, comprising: a rock drilling assembly, the rock drilling assembly including at least a rock drilling rod, the rock drilling rod having a dust suppressant channel along its axial direction, a first end of the dust suppressant channel being connected to a dust suppressant supply device, and a second end of the dust suppressant channel being connected to the atmosphere; wherein the rock drilling rod has an initial position before entering the mining and loading working face, and a dust suppression position for entering the interior of the target object to explosive pile-up, when the rock drilling rod is in the dust suppression position, dust suppressant is injected into the target object through the second end of the dust suppressant channel.
[0007] Furthermore, the dust suppressant channel includes a central through-hole and a transverse spray hole. The central through-hole is an axial extension of the rock drilling rod. One end of the central through-hole is connected to the dust suppressant supply device, and one end of the transverse spray hole is connected to the central through-hole. The other end of the transverse spray hole is connected to the atmosphere. The transverse spray hole is used to spray the dust suppressant into the interior of the target object.
[0008] Furthermore, there are multiple transverse nozzles, which are spaced apart along the circumferential direction of the rock drill rod to form a transverse nozzle group. In addition, the multiple transverse nozzle groups are spaced apart along the axial direction of the rock drill rod.
[0009] Furthermore, the axial centerline of the transverse nozzle has an angle α with the axial centerline of the rock drill rod, where 45°≤α≤75°.
[0010] Furthermore, the diameter of the transverse spray hole is
[0011] Furthermore, the rock drilling assembly also includes a hydraulic drive mechanism. The rock drilling rod is connected to the drive end of the hydraulic drive mechanism, which drives the rock drilling rod to reciprocate so that the rock drilling rod enters the interior of the target object in an impact vibration manner.
[0012] Furthermore, the explosion-generated dust suppression device includes a base, and the rock drilling components and dust suppressant supply device are all mounted on the base.
[0013] Furthermore, the dust suppressant supply device also includes: a storage tank, which is mounted on the base and is used to store the dust suppressant; a delivery pipe, the first end of which is connected to the storage tank and the second end of which is connected to the dust suppressant channel, which is used to inject the dust suppressant into the dust suppressant channel; and a pump body, which is mounted on the delivery pipe and is used to adjust the flow efficiency of the delivery pipe.
[0014] Furthermore, a cockpit is provided on the base for operating the rock drilling components.
[0015] Furthermore, a hydraulic drive valve group is also installed on the base. The hydraulic drive valve group is electrically connected to the cab and the hydraulic drive mechanism. The cab controls the movement of the hydraulic drive mechanism through the hydraulic drive valve group, thereby driving the rock drilling rod to move.
[0016] By applying the technical solution of this utility model, the rock drilling assembly and the dust suppressant supply device are used together for dust suppression operations inside the target object. The rock drilling rod has a hollow dust suppressant channel inside, and the dust suppressant supply device can inject the dust suppressant into the dust suppressant channel. The rock drilling rod has an initial position before entering the mining and loading face and a dust suppression position after entering the target object. After the rock drilling rod switches from the rock drilling position to the dust suppression position inside the target object, the dust suppressant supply device delivers the dust suppressant into the dust suppressant channel, thereby injecting the dust suppressant into the target object along with the dust suppressant channel. This allows the dust suppressant to reach the depth of the blasting and loading face, achieving wetting of the target object's interior and improving the dust suppression effect.

[0025] Combination Figure 1 As shown, according to a specific embodiment of this application, a dust suppression device for explosive piles is provided.
[0026] Specifically, such as Figure 1 As shown, the dust suppression device for explosive dumping includes a rock drilling assembly, which includes at least a rock drilling rod 2. Along the axial direction of the rock drilling rod 2, the rock drilling rod 2 has a dust suppressant channel 20. The first end of the dust suppressant channel 20 is connected to a dust suppressant supply device, and the second end of the dust suppressant channel 20 is connected to the atmosphere. The rock drilling rod 2 has an initial position before entering the mining and loading working face, and a position for entering the target object to perform explosive dumping and dust suppression. When the rock drilling rod 2 is in the dust suppression position, the dust suppressant is injected into the target object through the second end of the dust suppressant channel 20.
[0027] By applying the technical solution of this embodiment, the rock drilling assembly and the dust suppressant supply device are used together for dust suppression operations inside the target object. The rock drilling rod 2 has a hollow dust suppressant channel 20 inside. The dust suppressant supply device can inject the dust suppressant into the dust suppressant channel 20. The rock drilling rod 2 has an initial position before entering the mining and loading face and a dust suppression position after entering the target object. After the rock drilling rod 2 switches from the rock drilling position to the dust suppression position inside the target object, the dust suppressant supply device delivers the dust suppressant into the dust suppressant channel 20, so that the dust suppressant is injected into the target object along with the dust suppressant channel 20. This allows the dust suppressant to reach the depth of the blasting and loading face, achieving wetting of the target object's interior and improving the dust suppression effect.
[0028] Specifically, the dust suppressant channel 20 includes a central through-hole and a transverse spray hole 6. The central through-hole extends axially along the rock drill rod 2, with one end connected to a dust suppressant supply device. One end of the transverse spray hole 6 is connected to the central through-hole, and the other end is connected to the atmosphere. The transverse spray hole 6 is used to spray the dust suppressant into the target object. Dividing the dust suppressant channel 20 into a central through-hole and a transverse spray hole 6 allows the dust suppressant to flow axially along the rock drill rod 2, that is, the dust suppressant is transported from the dust suppressant supply device to the transverse spray hole 6 along the central through-hole. Since the other end of the transverse spray hole 6 is connected to the atmosphere, the dust suppressant can be sprayed out to the outside through the transverse spray hole 6, thereby suppressing dust on the target object outside the transverse spray hole 6.
[0029] It should be noted that when the rock drill rod 2 is in the dust suppression position, the transverse spray hole 6 is located inside the target object. When the dust suppressant is sprayed out through the transverse spray hole 6, it can directly suppress the dust inside the target object, thereby wetting the inside of the target object and improving the dust suppression effect.
[0030] Furthermore, such as Figure 1As shown, there are multiple transverse nozzles 6, which are spaced apart along the circumferential direction of the rock drill rod 2 to form transverse nozzle groups. Furthermore, these groups are spaced apart along the axial direction of the rock drill rod 2. This allows the dust suppressant to be evenly sprayed along the circumference of the rock drill rod 2 when it reaches a group of transverse nozzles, resulting in more uniform direction and dosage of the dust suppressant, expanding the dust suppression area, and improving the dust suppression effect. Simultaneously, when the transverse nozzle groups reach the interior of the target object, the dust suppressant can be sprayed and covered omnidirectionally within the target object, effectively suppressing large-area dust generation during blasting operations, reducing the impact of dust on the environment and workers, and also reducing dust wear on working equipment.
[0031] In one embodiment of this application, during the operation of the rock drill rod 2, as it moves from its initial position into the dust suppression position inside the target object, the dust suppressant supply device can be continuously and uninterruptedly in operation. That is, when the rock drill rod 2 is in the initial position, dust suppressant can be sprayed onto the mining and loading face through the transverse nozzle group to suppress dust. Furthermore, as the rock drill rod 2 enters the target object, the transverse nozzle group simultaneously sprays dust suppressant onto both the mining and loading face and the target object. And when the rock drill rod 2 is in the dust suppression position after entering the target object, the transverse nozzle group sprays dust suppressant onto the interior of the target object to wet the interior of the target object. Therefore, by setting multiple transverse nozzle groups at intervals along the axial direction of the rock drill rod 2, in conjunction with the dust suppressant supply device, the effect of simultaneously suppressing dust on both the mining and loading face and the interior of the target object can be achieved.
[0032] Furthermore, the axial centerline of the transverse nozzle 6 and the axial centerline of the rock drill rod 2 form an angle α, where 45°≤α≤75°. Based on the horizontal setting of the transverse nozzle 6, setting the axial centerline of the transverse nozzle 6 and the axial centerline of the central through hole at a certain angle allows the dust suppressant sprayed from the transverse nozzle group to expand outward in a conical shape. This creates a large coverage area both at the mining and loading face and inside the target object, enabling the rock drill rod 2 to wet a large area of the mining and loading face before entering the target object, further improving the dust suppression effect during open-pit mining.
[0033] Furthermore, the diameter of the transverse spray hole 6 is The diameter of each transverse spray hole 6 is set to a small diameter structure between 0.1mm and 1mm, so that the dust suppressant sprayed from the transverse spray hole 6 can be atomized. By using the atomized spray form, the dust suppressant can form fine water droplets, which can drift a greater distance in the air, thereby increasing the coverage area of the dust suppressant. At the same time, inside the target object, the atomized dust suppressant can penetrate into smaller cracks and pores, and can achieve a more comprehensive wetting effect inside the target object. In addition, using the atomized dust suppressant form can also reduce the amount of dust suppressant used, reduce water accumulation, and improve dust suppression efficiency.
[0034] Furthermore, the rock drilling assembly also includes a hydraulic drive mechanism. The rock drill rod 2 is connected to the drive end of the hydraulic drive mechanism, which drives the rock drill rod 2 to reciprocate, so that the rock drill rod 2 enters the interior of the target object through impact vibration. By using impact vibration, the drilling efficiency of the rock drill rod 2 can be improved, the energy consumption of the equipment can be reduced, and efficient and precise entry into the interior of hard target objects can be achieved.
[0035] It should be noted that the drive end of the hydraulic drive mechanism can also drive the rock drill rod 2 to rotate. The rotation of the rock drill rod 2 can further enable the transverse spray nozzle group to spray dust suppressant at all angles along the circumference of the rock drill rod 2. It can also be combined with the impact vibration motion mode to facilitate the rock drill rod 2 to enter the interior of the target object.
[0036] Specifically, such as Figure 1 As shown, the explosive pile dust suppression device includes a base 1, on which both the rock drilling assembly and the dust suppressant supply device are mounted. The base 1 provides greater stability to the entire device. When the rock drilling assembly enters the target object using impact vibration, the base 1 provides stable support. Furthermore, the integrated mounting of the rock drilling assembly and the dust suppressant supply device on the base 1 allows the dust suppressant supply device to be positioned close to the rock drilling assembly, facilitating rapid spraying of the dust suppressant and improving the device's working efficiency.
[0037] In one embodiment of this application, the base 1 is movably arranged, that is, the explosive pile dust suppression device can be flexibly moved through the base 1, driving the rock drilling components and the dust suppression supply device to move flexibly in the mining and loading face, realizing the internal dust suppression operation of target objects in different mining and loading faces and corresponding positions, thus improving the practicality of the device.
[0038] Furthermore, such as Figure 1As shown, the dust suppressant supply device also includes a storage tank 3, a delivery pipe 5, and a pump body 4. The storage tank 3 is mounted on the base 1 and is used to store the dust suppressant. The first end of the delivery pipe 5 is connected to the storage tank 3, and the second end of the delivery pipe 5 is connected to the dust suppressant channel 20. The delivery pipe 5 is used to inject the dust suppressant into the dust suppressant channel 20. The pump body 4 is mounted on the delivery pipe 5 and is used to adjust the flow efficiency of the delivery pipe 5. The delivery pipe 5 connects the storage tank 3 and the dust suppressant channel 20, and the pump body 4 is mounted on the delivery pipe 5. The pump body 4 can control and adjust the flow rate and delivery speed of the dust suppressant, thereby achieving different adjustments to the degree of dust suppressant spraying. This makes the supply of dust suppressant more stable, and the injection speed of the dust suppressant can be adjusted in real time according to the operational needs to ensure that the supply of dust suppressant meets the dust suppression effect and avoids waste of dust suppressant. At the same time, in the case of continuous operation, it can ensure the continuous supply of dust suppressant and reduce the impact of dust on the operation.
[0039] Furthermore, a driver's cab is installed on the base 1 for operating the rock drilling components. The driver's cab facilitates the operator's control of the rock drilling components and dust suppressant supply device. Located inside the cab, the operator is away from the working face, avoiding damage from impacts and vibrations, thus improving operational safety. Inside the cab, the operator can remotely activate the hydraulic drive mechanism to control the movement trajectory of the rock drill rod 2 and control the pump 4 via the control panel, setting the dust suppressant spraying parameters to ensure high efficiency and precision in operation.
[0040] Furthermore, a hydraulic drive valve assembly is also installed on the base 1. The hydraulic drive valve assembly is electrically connected to the cab and the hydraulic drive mechanism. The cab controls the movement of the hydraulic drive mechanism through the hydraulic drive valve assembly, thereby driving the rock drilling rod 2 to move. The installation of the hydraulic drive valve assembly can improve the accuracy of control over the hydraulic drive mechanism, and also improve the safety and ease of operation.
[0041] This application also provides a preferred embodiment of a dust suppression device for explosive piles, combined with Figure 1 As shown.
[0042] Specifically, the explosion-generated dust suppression device includes a base 1, on which a rock drill rod 2 is installed. The rock drill rod 2 has an axial hole inside. The explosion-generated dust suppression device also includes a liquid storage tank 3 installed on the top of the driver's cab of the base 1, a pump body 4 installed on the liquid storage tank 3, a suction pipe with one end located inside the liquid storage tank 3 and the other end connected to the pump body inlet, and a water delivery pipe with one end connected to the pump body outlet and the other end connected to the axial hole on the rock drill rod 2. The rock drill rod 2 has transverse spray holes 6 connected to the axial hole on its pipe wall. The transverse spray holes 6 are evenly distributed along the radial direction of the rock drill rod 2 to form a transverse spray hole group. Several groups of transverse spray holes are arranged in an array from the front end of the rock drill rod 2 to the rear.
[0043] During operation, the machine base 1 uses a hydraulic cylinder to drive the rock drill rod 2 to reciprocate, causing the rock drill rod 2 to enter the target object in the open-pit mine blasting pile through impact vibration. Water or other forms of liquid dust suppressant enter the axial hole of the rock drill rod 2 under the drive of the pump body 4, and are sprayed out from the transverse spray hole 6 on the rock drill rod 2 under high pressure. The sprayed water mist diffuses into the gaps of the target object, thereby wetting the inside of the target object in the open-pit mine blasting pile, thus improving the dust suppression effect during the open-pit mine mining and loading process.
[0044] The centerline of the transverse nozzle 6 intersects the axis of the rock drill rod 2 at 45°-75°, causing the dust suppressant sprayed from the transverse nozzle 6 to expand outward in a conical shape, forming a large coverage area. This allows for large-area wetting of the mining and loading face before the rock drill rod 2 enters the blast pile, further improving the dust suppression effect of open-pit mining and loading.
[0045] The transverse spray hole 6 is an atomizing spray hole with a diameter of 0.1mm-1mm, which makes the dust suppressant sprayed from the transverse spray hole 6 into a mist, which can further increase the coverage area of the dust suppressant and improve the dust suppression effect.
[0046] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0047] 1) The rock drill rod 2 can be submerged into the blast pile. The liquid dust suppressant is sprayed out from the transverse nozzle 6 of the rock drill rod 2 under the high pressure drive of the pump body 4, thereby wetting the inside of the target object in the open-pit mine blast pile, which can improve the dust suppression effect during the open-pit mine mining and loading process.
[0048] 2) The transverse nozzle 6 of the rock drill rod 2 intersects the axis of the rock drill rod 2 at 45°-75°, so that the dust suppressant sprayed from the transverse nozzle 6 expands outward into a cone shape, which can form a large coverage area. Thus, before the rock drill rod 2 enters the target object of the explosion, it can also wet a large area of the working face, which can further improve the dust suppression effect of open-pit mining.
[0049] 3) The rock drill rod 2 enters the target object of the blast pile by impact vibration. The vibration can further open the pores inside the target object, allowing the dust suppressant to spread over a wider area inside the target object of the blast pile, thereby further improving the dust suppression effect.
