Description

Technical Field

[0001] This utility model relates to the technical field of spray dust suppression equipment, and in particular to an intelligent spray dust suppression device for port storage yards. Background Technology

[0002] Port storage yards are important transshipment and storage areas for bulk commodities such as coal and ore. During the loading, unloading, stacking, and transshipment of goods, large amounts of dust are easily generated, polluting the environment and endangering the health of workers. Therefore, installing dust suppression spray systems in storage yards is currently a common and primary control method.

[0003] Existing dust suppression spraying systems typically use high-pressure water mist to spray onto stockpiles, wetting and fixing dust on the material surfaces. To achieve wide coverage, these systems are often equipped with high-powered fans to project the water mist.

[0004] However, since port yards are inherently high-dust working environments, the sprinkler system inevitably draws in large amounts of air containing dust and debris during operation. To protect the impellers and motors inside the fans from wear or blockage, these devices typically have filter plates installed at the fan inlet.

[0005] As operating time accumulates, the filter plates will quickly become clogged with dust, resulting in reduced airflow to the fan and shortened spray range, which seriously affects the dust suppression effect. Therefore, frequent cleaning or replacement is required.

[0006] In existing technologies, filter plates are mostly fixed to the equipment housing using bolts or other traditional fasteners. Because spray systems are typically large and installed at a high position, maintenance personnel must carry tools and work at heights to replace filter plates, which is extremely inconvenient, time-consuming, labor-intensive, and poses serious safety hazards. This cumbersome and dangerous maintenance method results in long equipment downtime, high maintenance costs, and reduces the overall operating efficiency of the dust suppression system in the stockyard.

[0007] Therefore, this utility model proposes an intelligent spray dust suppression device for port storage yards to address the shortcomings of existing technologies. Utility Model Content

[0008] In view of the problems of existing intelligent spray dust suppression devices for port yards, such as complicated filter plate replacement and maintenance, inconvenient operation, safety hazards, and poor dust suppression effect due to fixed spray angles that cannot fully cover the materials in the yard, this utility model aims to provide an intelligent spray dust suppression device for port yards with an improved structure that can effectively solve the above problems.

[0009] This utility model provides an intelligent spray dust suppression device for port storage yards, comprising: a mounting base; a rotating shaft rotatably connected to the mounting base; a spray dust suppression machine fixedly connected to the rotating shaft; a fan disposed inside the spray dust suppression machine; a filter plate detachably mounted on the spray dust suppression machine; a quick-release mechanism; and an angle adjustment mechanism. The quick-release mechanism is used to lock and release the filter plate, and includes: a sliding rod that slides axially and is rotatable; a knob fixedly connected to the outer end of the sliding rod; and a limiting component fixedly connected to the inner end of the sliding rod. A limiting groove is provided on the spray dust suppression machine, and the limiting component includes a limiting rod for plugging and unplugging into the limiting groove to lock the axial position of the sliding rod. Furthermore, the angle adjustment mechanism is disposed within the mounting base and used to drive the rotating shaft to rotate. The angle adjustment mechanism includes: a gear fixedly connected to the rotating shaft; a rack plate meshing with the gear; a cylinder; and an electric push rod, the cylinder and the electric push rod being used to drive the rack plate to slide linearly.

[0010] Preferably, the quick-release mechanism further includes a baffle fixed to the sliding rod, which extends radially along the sliding rod to provide an axial action surface for the spring to transmit the spring force.

[0011] Preferably, the quick-release mechanism further includes a spring, which is sleeved on the sliding rod and located between the baffle and the inner wall of the spray dust suppressor; the spring is preferably a compression spring, whose axis coincides with the axis of the sliding rod, and is used to provide preload.

[0012] Preferably, the spring force is used to push the baffle, thereby causing the sliding rod to be stressed, so as to ensure that after the limiting rod is inserted into the limiting groove, it can be stably held in the locking position in the limiting groove by the spring force, thereby realizing automatic locking and improving the reliability of vibration and loosening resistance.

[0013] Preferably, the limiting rod drives the sliding rod to rotate by operating the knob, thereby realizing the circumferential movement of the limiting rod, so that it aligns with or deviates from the limiting groove, thereby realizing the engagement or disengagement of the sliding rod in the axial direction.

[0014] Preferably, the angle adjustment mechanism further includes a sliding groove, which is formed in the mounting base, and the rack plate is slidably connected in the sliding groove; the sliding groove provides guidance and support for the linear movement of the rack plate, ensuring that the rack plate can slide smoothly when subjected to force and maintain a precise meshing relationship with the gear.

[0015] Preferably, the non-driving end of the electric actuator is fixedly connected to the driving end of the cylinder; this series power layout allows the cylinder, as the first-stage drive, to cause the entire base of the electric actuator to shift during its extension and retraction.

[0016] Preferably, the drive end of the electric push rod is fixedly connected to the rack plate; based on the above connection relationship, the extension and retraction action of the electric push rod itself serves as the second-level fine drive, and its extension and retraction displacement is superimposed with the overall displacement driven by the cylinder to jointly achieve the control of the total stroke of the rack plate, thereby adjusting the angle of the spray dust suppression machine.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting a quick-release mechanism, uses a knob to drive the sliding rod to move, and cooperates with the locking of the limit rod and the limit groove and the elasticity of the spring to achieve locking and unlocking. It solves the problems of complicated replacement and maintenance of the filter plate of the spray device and inconvenient operation in the prior art, and achieves the effects of quick disassembly and installation of the filter plate, reliable locking and convenient maintenance, effectively protecting the fan.

[0018] 2. This utility model, by setting an angle adjustment mechanism, uses a cylinder and an electric push rod to drive a rack plate to slide in a sliding groove. The rack plate meshes with a gear fixed on a rotating shaft to drive the spray dust suppression machine to rotate. This solves the problem in the prior art that the spraying device has a fixed angle, cannot adapt to different shapes of stacked goods, and results in incomplete spraying coverage. It achieves the effect of making the spraying angle of the spray dust suppression machine precisely adjustable and realizing full coverage, thus improving the dust suppression efficiency.

[0019] 3. This utility model integrates the quick-release mechanism with the angle adjustment mechanism, which not only enables the device to adjust the angle but also greatly simplifies the maintenance difficulty in high dust environments. It solves the dual problems of difficult equipment maintenance and poor spraying effect in port yard environments, achieving the technical effect of compact structure, complete function and stable and reliable operation.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 7 This utility model provides an intelligent spray dust suppression device for port yards, which aims to solve the problems of complex replacement and maintenance of the filter plate 51 of the spray device and the inability of fixed-angle spraying to fully cover the materials in the yard in the prior art.

[0025] like Figure 1 , Figure 2 and Figure 6 As shown, the intelligent spray dust suppression device for port yards includes a mounting base 1 and a rotating shaft 2 rotatably connected to the mounting base 1. The mounting base 1 serves as the mounting base for the entire device, and the rotating shaft 2 is used to transmit rotational power. The spray dust suppression machine 3 is fixedly connected to the rotating shaft 2. The spray dust suppression machine 3 rotates with the rotating shaft 2 to adjust the spray angle. A fan 4 is installed inside the spray dust suppression machine 3. The fan 4 is used to generate an airflow that sprays water mist. A filter plate 51 is detachably installed on the spray dust suppression machine 3. The filter plate 51 is used to filter the air entering the fan 4.

[0026] Reference Figures 2 to 5The quick-release mechanism 5 includes a sliding rod 52 that slides axially and can rotate. The outer end of the sliding rod 52 is fixedly connected to a knob 53. The knob 53 is used for workers to push, pull, and rotate the sliding rod 52. The inner end of the sliding rod 52 is fixedly connected to a limiting assembly 56. The limiting assembly 56 includes a limiting rod 561. The spray dust suppressor 3 has a corresponding limiting groove 562 for the limiting rod 561 to engage or disengage. The limiting rod 561 engages or disengages from the limiting groove 562 by rotating the sliding rod 52, and... The axial sliding of the sliding rod 52 enables the abutment, locking, or release of the filter plate 51. The quick-release mechanism 5 also includes a baffle 54 fixed on the sliding rod 52, and a spring 55 sleeved on the sliding rod 52 and located between the baffle 54 and the inner wall of the spray dust suppressor 3. This structure uses the elastic force of the spring 55 to push the baffle 54, thereby causing the sliding rod 52 to be stressed, ensuring that the limiting rod 561 is kept in the locked position within the limiting groove 562, achieving reliable automatic locking and preventing the filter plate 51 from loosening and falling off during equipment operation.

[0027] Reference Figure 1 , Figure 6 and Figure 7 The angle adjustment mechanism 6 includes a gear 65, which is fixedly connected to the rotating shaft 2 and meshes with the rack plate 64. The angle adjustment mechanism 6 also includes a sliding groove 62, in which the rack plate 64 is slidably connected. The sliding groove 62 provides precise guidance and limit for the linear movement of the rack plate 64. The power drive assembly of the angle adjustment mechanism 6 consists of a cylinder 61 and an electric push rod 63. The cylinder 61 is located in the mounting base 1 and is used to provide power or auxiliary drive. The electric push rod 63 is located in the mounting base 1. The non-driving end of the electric push rod 63 is fixedly connected to the driving end of the cylinder 61 and is used to receive the drive from the cylinder 61. The driving end of the electric push rod 63 is fixedly connected to the rack plate 64. The electric push rod 63 drives the rack plate 64 to slide linearly in the sliding groove 62 by extension and retraction, and then drives the rotating shaft 2 to rotate through the meshing of the gear 65 and the rack plate 64.

[0028] The quick-release mechanism 5 includes a baffle 54, which is fixed to the sliding rod 52. The quick-release mechanism 5 also includes a spring 55, which is sleeved on the sliding rod 52 and located between the baffle 54 and the inner wall of the spray dust suppressor 3. The elastic force of the spring 55 is used to push the baffle 54, thereby causing the sliding rod 52 to be subjected to outward force, ensuring that the limiting rod 561 can be stably locked in the limiting groove 562, preventing accidental unlocking during equipment vibration or operation. The limiting rod 561 of the limiting assembly 56 drives the sliding rod 52 to rotate through the knob 53, thereby locking into or disengaging from the limiting groove 562.

[0029] The implementation principle of this application embodiment is as follows: Based on real-time monitored environmental data such as dust concentration and weather, the spray dust suppressor 3, which can be adjusted by rotating shaft 2 on the mounting base 1 in the yard, is automatically scheduled to spray water mist onto the surface of the goods precisely, at regular intervals, and in quantitative amounts, thereby fixing dust particles on the material surface and achieving the purpose of suppressing dust. A fan 4 is also installed inside the spray dust suppressor 3. To protect the fan 4, a filter plate 51 is added to intercept solid particles such as dust and debris in the air, preventing them from entering the fan 4 and causing wear, blockage, or malfunction. When the filter plate 51 is damaged and needs to be replaced, it is removed and replaced through the quick-release mechanism 5. The operator pushes the knob 53 to move the sliding rod 52, and at the same time, the sliding rod 52 moves the limit component. The limiting rod 561 inside 56 moves, and then the limiting rod 561 is disengaged from the limiting groove 562 by rotation. Then the knob 53 is pulled outward to make the sliding rod 52 drive the limiting rod 561 to slide into the spray dust suppressor 3. At this time, the fixing of the filter plate 51 is released and it can be removed. During installation, simply place the filter plate 51, press it to make the sliding rod 52 drive the limiting rod 561 to move, and at the same time, the baffle 54 fixed outside the sliding rod 52 squeezes the spring 55. Then the limiting rod 561 enters the limiting groove 562 by rotation. At this time, the applied force is released, the spring 55 rebounds the baffle 54, and then the sliding rod 52 is subjected to force. At the same time, the limiting rod 561 is locked into the limiting groove 562, thereby achieving the purpose of fixing the filter plate 51, thus achieving the effect of quick installation and disassembly.

[0030] The cargo storage patterns in the port yard vary greatly, making it difficult for a fixed-angle spray to achieve full coverage. Therefore, it is necessary to adjust the angle of the spray dust suppression machine 3. When the angle needs to be adjusted, it is achieved through the angle adjustment mechanism 6. By activating the cylinder 61 in the mounting base 1, the drive end of the cylinder 61 is fixedly connected to the electric push rod 63, causing the electric push rod 63 to extend and retract. In turn, the drive end of the electric push rod 63 drives the rack plate 64, which is fixedly connected to it, to slide linearly in the sliding groove 62. Because the teeth of the rack plate 64 mesh with the teeth of the gear 65, the gear 65 rotates when the rack plate 64 is pushed. In turn, the gear 65 drives the fixed rotating shaft 2 to rotate, and at the same time, the rotating shaft 2 drives the spray dust suppression machine 3 to adjust its angle, thereby achieving the effect of angle adjustment.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
