Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a dust suppression control device for predicting moisture content. Background Technology

[0002] Dust generation and dispersion are common problems in environments such as mining, material transportation, construction, and road maintenance. Dust not only pollutes the environment but also seriously threatens the health of workers. Currently, spraying liquids (such as water or dust suppressants) is one of the most common and effective means of suppressing dust dispersion.

[0003] Most existing dust suppression devices use fixed spray flow rates or simple start / stop controls. This "one-size-fits-all" control method lacks adaptability to the on-site environment. In actual operation, the moisture content of the air is constantly changing; when the air is too dry, a fixed spray volume may not be sufficient to effectively suppress dust, resulting in poor dust suppression; while when the air humidity is already high, continuing to spray at a fixed flow rate will waste liquid resources and may even cause the material to become overly wetted, affecting subsequent processing or transportation.

[0004] Currently, most dust suppression equipment on the market lacks the ability to sense ambient humidity (i.e., moisture content) in real time, and is even less able to precisely adjust the liquid spraying rate based on real-time humidity data. Operators can only rely on experience for rough adjustments, resulting in extremely low levels of intelligence and precision in dust suppression control, making it difficult to find a balance between ensuring dust suppression effectiveness and conserving resources.

[0005] Therefore, this utility model proposes a dust suppression control device based on moisture content prediction to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems of existing dust suppression control devices based on moisture content prediction, such as the inability to accurately adjust the spray flow rate according to the real-time humidity of the environment, resulting in poor dust suppression effect or liquid waste, and the complex structure of the filter components, which are inconvenient to maintain and prone to clogging, this utility model aims to provide a dust suppression control device based on moisture content prediction with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a dust suppression control device for predicting moisture content, including: a support plate, a filter mechanism, a first filter assembly, an adjustment mechanism, a second filter assembly, a water pump, a spray pipe, and a humidity predictor.

[0008] The filtration mechanism is fixed to the top of the support plate. The filtration mechanism includes a filter tank, a filter screen disposed inside the filter tank, an annular pipe connected to the filter screen, an inlet pipe connected to the annular pipe, and a drain pipe fixed to the bottom of the filter tank.

[0009] The filter assembly includes a filter tube that is detachably connected to the outlet end of the drain pipe; the filter assembly also includes a filter screen fixed inside the filter tube, a spring fixed to the right side of the filter screen, and a spherical block fixed to the right side of the spring.

[0010] The second filter assembly includes a delivery pipe threaded to the outlet end of the filter pipe; the second filter assembly also includes a filter screen fixed inside the delivery pipe, a spring fixed to the left side of the filter screen, a spherical block fixed to the left side of the spring, and a movable column fixed to the left side of the spherical block.

[0011] The water pump is fixed to the top of the support plate and connected to the outlet end of the delivery pipe, and the jet pipe is connected to the outlet end of the water pump.

[0012] The adjustment mechanism includes a filter disc that is rotatably installed inside the filter tube, a lever that passes through the wall of the filter tube and is connected to the filter disc, a spring three that is sleeved inside the lever, a fixed column that is sleeved on the inner wall of the spring three, and a ball block that is movably installed inside the lever.

[0013] Preferably, in order to facilitate observation of the internal condition of the filter tank and to achieve online cleaning, a transparent observation window is provided on the front side of the filter tank; and the liquid inlet pipe is used to connect the cleaning liquid, and multiple nozzles are connected to the inner wall of the annular pipe, which face the surface of the filter screen for rinsing.

[0014] Preferably, during the tightening process of the threaded connection between the conveying pipe and the filter pipe, the moving column will come into contact with the spherical block, and the contact force will simultaneously compress the spring and the second spring, generating a preload force.

[0015] Preferably, as a further limitation of the above connection method, when the delivery pipe is fully connected to the right side of the filter pipe, the moving column and the spherical block engage with each other to form a stable mechanical lock.

[0016] Preferably, in order to achieve sliding and liquid flow within the components, the spherical block is made into a hollow structure and is slidably disposed inside the filter tube; at the same time, the moving column is slidably disposed inside the delivery tube.

[0017] Preferably, in order to achieve position locking of the adjustment mechanism, a groove is opened on the outer wall of the filter tube. Under the action of the reset elastic force of the spring three, the ball can be engaged with the groove, thereby stably fixing the lever in any position after adjustment.

[0018] Preferably, in order to facilitate quick disassembly and replacement of filter assembly 1, the filter tube is detachably connected to the drain pipe through a flange structure; and the filter plate rotatably disposed inside the filter tube contacts the spring 1 to form a linkage or support relationship.

[0019] Preferably, the lever is used to drive the filter to rotate. This rotation operation can be used to adjust the flow rate of the liquid flowing through the filter tube according to the real-time humidity data displayed by the humidity predictor, so as to achieve precise control.

[0020] This utility model has the following beneficial effects: 1. This utility model solves the problems in existing dust suppression devices where liquid impurities easily clog nozzles, affecting dust suppression effect and causing short service life of the filter device. It achieves the technical effect of significantly improving liquid filtration accuracy, effectively avoiding impurities clogging water pumps and spray nozzles, ensuring the stability of dust suppression effect, and facilitating online cleaning, thus extending the service life of the filter screen.

[0021] 2. This utility model, by setting up a humidity predictor and adjustment mechanism, uses a lever to drive the filter plate inside the filter tube to rotate to change the flow area, and the ball block, spring and groove on the outer wall of the filter tube to form a locking structure for stable positioning. This solves the problem in the prior art that the spray flow of dust suppression devices is fixed and cannot be adjusted according to changes in ambient humidity, resulting in poor dust suppression effect or excessively wet materials. It achieves precise control of liquid flow rate according to real-time humidity, ensures stable state after flow rate adjustment, realizes on-demand spraying, not only improves the dust suppression effect, but also avoids liquid waste.

[0022] 3. This utility model solves the problems of complex structure, inconvenient filter element replacement and disassembly, and low maintenance efficiency of existing filter devices by designing filter component one and filter component two as independent modules connected by threads, and by using internal moving columns, spherical blocks and springs to achieve pre-tightening and final locking positioning during the tightening process. It makes the replacement process of the core filter components simple and quick, and can be completed without complicated tools, which greatly improves the maintenance convenience of the equipment and reduces downtime maintenance time.

[0025] 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.

[0026] Example: Please refer to Figures 1 to 5 This utility model provides a dust suppression control device for predicting moisture content, which aims to solve the problems of poor dust suppression effect caused by easy clogging of nozzles, inconvenient maintenance of filter components, and inability to flexibly adjust the spray volume according to real-time humidity in existing dust suppression devices.

[0027] like Figures 1 to 5 As shown, the dust suppression control device for predicting moisture content includes a support plate 1, a filter mechanism 2, a water pump 4, and a spray pipe 5 connected to the outlet end of the water pump 4, all fixed to the top of the support plate 1. The filter mechanism 2 is used to filter the liquid, and the regulating mechanism 3 is set in the filtration process to regulate the flow rate. The filtered liquid enters the water pump 4 for pressurization and is finally discharged through the spray pipe 5. The humidity predictor 6 is used to detect and display the moisture content. The filtration mechanism 2 includes a filter tank 21, which is equipped with a filter screen 22. The filter tank 21 is fixed to the top of the support plate 1, and the bottom of the filter tank 21 is fixed to the drain pipe 25 for discharging the liquid that has been preliminarily filtered by the filter screen 22. The filtration mechanism 2 also includes an annular pipe 23 and an inlet pipe 24. The annular pipe 23 is connected to the filter screen 22, and the inlet pipe 24 is connected to the annular pipe 23. The filter assembly 26 is detachably connected to the outlet end of the drain pipe 25. The filter assembly 26 includes a filter tube 261, a filter screen 262 is fixed inside the filter tube 261, a spring 263 is fixed to the right side of the filter screen 262, and a spherical block 264 is fixed to the right side of the spring 263. The filter assembly 27 includes a delivery pipe 271, which is threaded to the outlet end of the filter pipe 261 and connected to the water pump 4. A filter screen 272 is fixed inside the delivery pipe 271. A spring 273 is fixed to the left side of the filter screen 272. A spherical block 274 is fixed to the left side of the spring 273. A movable column 275 is fixed to the left side of the spherical block 274. The adjustment mechanism 3 includes a filter plate 31 rotatably disposed inside the filter tube 261, a lever 32 passing through the wall of the filter tube 261 and connected to the filter plate 31, a spring 33 sleeved inside the lever 32, a fixing post 34 sleeved inside the spring 33, and a ball block 35 movably disposed inside the lever 32.

[0028] In the assembled state, the delivery pipe 271 is threadedly connected to the filter pipe 261. As the delivery pipe 271 approaches the filter pipe 261, the movable column 275, which is slidably disposed inside the delivery pipe 271, comes into contact with the spherical block 264, which is slidably disposed inside the filter pipe 261. This contact causes the movable column 275 to compress the spring 273, and at the same time, the spherical block 264 compresses the spring 263. When the delivery pipe 271 is fully connected to the right side of the filter pipe 261, the movable column 275 and the spherical block 264 engage. This connection structure, which achieves internal spring pre-tensioning and final engagement through threaded tightening, ensures the tightness of the connection between the filter assembly 26 and the filter assembly 27. The filter pipe 261 is detachably connected to the drain pipe 25 via a flange. The spherical block 264 has a hollow structure to facilitate liquid passage. The lever 32 of the adjustment mechanism 3 passes through the wall of the filter tube 261 and is connected to the filter plate 31 rotatably disposed inside the filter tube 261. The filter plate 31 is in contact with the spring 263. A groove is opened on the outer wall of the filter tube 261. The ball block 35, which is movably disposed inside the lever 32, is engaged with the groove under the return force of the spring 33. The spring 33 is sleeved inside the lever 32, and the fixing post 34 is sleeved on the inner wall of the spring 33. This locking structure, which is achieved by the lever 32, the ball block 35, and the spring groove, allows the operator to move the lever 32. The lever 32 drives the filter plate 31 to rotate, so as to adjust the flow rate of the liquid flowing through the filter tube 261 according to the humidity displayed by the humidity predictor 6. After adjustment, the ball block 35 engages with the groove to fix the position of the lever 32. The front of the filter tank 21 is provided with a transparent observation window for observation. The inlet pipe 24 is used to connect the cleaning fluid. The cleaning fluid passes through the annular pipe 23 and is sprayed out by multiple nozzles connected to the inner wall of the annular pipe 23. The multiple nozzles face the surface of the filter screen 22 to achieve online cleaning of the filter screen 22.

[0029] In a preferred embodiment, the filter tank 21 has a transparent observation window on its front side, and the inlet pipe 24 is used to receive the cleaning fluid. The cleaning fluid passes through an annular pipe 23 connected to the filter screen 22 and is sprayed onto the surface of the filter screen 22 by multiple nozzles connected to the inner wall of the annular pipe 23. During the threaded connection between the delivery pipe 271 and the filter pipe 261, the moving column 275 contacts the spherical block 264. This contact compresses the spring 263 fixed on the right side of the filter screen 262 and the spring 273 fixed on the left side of the filter screen 272. When the delivery pipe 271 is fully connected to the right side of the filter pipe 261, the moving column 275 and the spherical block 264 engage, forming a stable mechanical lock. The spherical block 264 is the center... The filter tube 261 has an empty structure, with a spherical block 264 slidably disposed inside the filter tube 261. Simultaneously, a movable column 275 is slidably disposed inside the conveying pipe 271. A groove is formed on the outer wall of the filter tube 261. The spherical block 35 engages with the groove under the restoring force of a spring 33 sleeved outside the fixed column 34, thereby stably fixing the lever 32 in the adjusted position. The filter tube 261 is detachably connected to the drain pipe 25 via a flange. Furthermore, the filter disc 31, rotatably disposed inside the filter tube 261, contacts the spring 263. The lever 32 drives the filter disc 31 to rotate, which adjusts the liquid flow rate through the filter tube 261. The operator can operate according to the humidity data displayed by the humidity predictor 6.

[0030] The implementation principle of this application embodiment is as follows: The dust suppression control device for predicting moisture content mainly consists of a filter mechanism 2, an adjustment mechanism 3, a water pump 4, and a spray pipe 5 arranged in sequence. The humidity predictor 6 detects the air moisture content and displays it on the surface of the humidity predictor 6. The liquid to be filtered enters the filter mechanism 2 for filtration, then the flow rate is adjusted by the adjustment mechanism 3, and then it is transported to the water pump 4 fixed on the top of the support plate 1 for pressurization. Finally, it is discharged into the air through the spray pipe 5 to carry out dust suppression work.

[0031] During the filtration process of the filter mechanism 2 fixed to the top of the support plate 1, the liquid first enters the filter tank 21 through the inlet at the top of the filter tank 21 and undergoes initial filtration through the filter screen 22. Then, it enters the filter assembly 26 connected to the drain pipe 25 via a flange through the detachable drain pipe 25 at the bottom of the filter tank 21. The filter assembly 26 includes a filter tube 261, a filter screen 262 fixed inside the filter tube 261, a spring 263 fixed to the right side of the filter screen 262, and a spherical block 264 fixed to the right side of the spring 263. During the transport of the liquid inside the filter tube 261, the liquid flow rate is adjusted by the regulating mechanism 3 and filtered by the filter screen 262. A second filtration is performed. The spherical block 264 has a hollow structure to facilitate liquid transport. The liquid then enters the filter assembly 27 through the filter tube 261. The filter assembly 27 includes a delivery tube 271, a filter screen 272 fixed inside the delivery tube 271, a spring 273 fixed to the left side of the filter screen 272, a spherical block 274 fixed to the left side of the spring 273, and a movable column 275 fixed to the left side of the spherical block 274. During the transport of the liquid inside the delivery tube 271, it undergoes a final filtration through the filter screen 272. Then, it enters the water pump 4 and is transported to the spray pipe 5. Through multiple nozzles fixed to the outer wall of the spray pipe 5, a dust suppression effect is achieved.

[0032] The device requires periodic replacement of two components: filter assembly 26 and filter assembly 27. The delivery pipe 271 is threadedly connected to the filter pipe 261. To disassemble filter assembly 27, simply rotate the entire assembly; it will then be removed. Filter assembly 26 can then be removed from the right side of the drain pipe 25, completing the replacement of both components. A new filter assembly 26 is then installed, followed by filter assembly 27 installed to the right of filter assembly 26. As the delivery pipe 271 approaches the filter pipe 261, the sliding column 275 inside the delivery pipe 271 contacts the sliding spherical block 264 inside the filter pipe 261. Subsequently, the spherical block... Both the spring 263 on the left side of the first block 264 and the spring 273 on the right side of the second spherical block 274 are compressed. When the delivery pipe 271 is fully connected to the right side of the filter pipe 261, the moving column 275 engages with the first spherical block 264, completing the installation of the second filter assembly 27. The impurities attached to the inside of the filter tank 21 and the surface of the filter screen 22 can be observed through the transparent observation window on the front side of the filter tank 21. The liquid inlet pipe 24 fixed on the front side of the filter tank 21 is connected to the cleaning liquid, and the surface of the filter screen 22 is cleaned through multiple nozzles connected to the inner wall of the annular pipe 23 connected to the filter screen 22. This ensures that the inside of the filter tank 21 is free of impurities, extends the service life of the filter screen 22, greatly improves the liquid filtration accuracy, and prevents impurities from clogging the nozzles and affecting the dust suppression effect.

[0033] During the process of adjusting the liquid flow rate by the regulating mechanism 3, the filter plate 31 can rotate inside the filter tube 261. At the same time, the filter plate 31 contacts the spring 263. When the humidity predictor 6 displays that the humidity is too low, the lever 32 is pushed upwards, so that the lever 32 is at the top of the groove on the front side of the filter tube 261. During the process of pushing the lever 32, the ball block 35 moves into the lever 32, and at the same time, it compresses the fixing post 34 sleeved on the outer wall of the spring 263. When the right side of spring 33 moves and the lever 32 is moved to the desired position, spring 33 drives ball 35 to reset. Then ball 35 engages with the groove on the front side of filter tube 261. At this time, the flow rate inside filter tube 261 is at its maximum. When the humidity predictor 6 shows that the humidity is too high, the lever 32 can be moved down to ensure that the state is stable after the flow rate is adjusted. This device can accurately control the liquid flow rate in real time according to the humidity, avoiding the problem of poor dust suppression effect or excessive material moisture caused by improper flow rate.

[0034] 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.
