Description

Technical Field

[0001] The present application relates to the technical field of spray dust suppression, and in particular to an intelligent spray dust suppression system for a silo. Background Art

[0002] The spray dust suppression system, also called the dry fog dust suppression system, uses a high-speed gas-liquid mixed liquid flow to generate ultrasonic oscillation, splits the gas-liquid mixture into a dust suppression mixed liquid mist with a particle size of about 10μm, and sprays it above the dust-raising point to form a "dust suppression cloud layer" of a certain thickness, which surrounds the dust under the "dust suppression cloud layer". When the dust rises with the airflow through the "cloud layer", on the one hand, the dust suppression mixed liquid droplets will combine with the dust particles ("agglomeration" effect), and the dust particles will continue to gather and settle, achieving the purpose of dust reduction and air purification; on the other hand, when the dust particles in the air that are soaked by the dust suppression mixed liquid droplets fall on the surface of the material pile, they will also make the material surface wet, thereby suppressing the surface fine particles of dust from being raised.

[0003] In the existing related technologies, the spray dust suppression system mainly includes an air compressor, an exhaust pipe, a dry fog machine and a sprayer. When the dry fog is sprayed out from the sprayer, the dust reduction effect can be achieved. However, the existing sprayer is generally installed on a bracket or platform through a universal joint assembly, and can only perform simple angle adjustments through the universal joint, which is difficult to meet diverse usage requirements. Summary of the invention

[0006] By adopting the above technical solution, when the slider slides in the slide groove, it can drive the shell to slide on the top of the base, thereby changing the relative position of the shell and the base, so that the dry mist sprayed from the spray head can fully cover the top of the silo and fall from the top of the silo to the bottom of the silo, and in this process, the dust suppression operation of the silo can be reliably achieved. Furthermore, since a number of independent shells are provided on the base, by driving each shell separately, the spray range of the spray head can be reliably adjusted, thereby reliably suppressing dust.

[0012] By adopting the above technical solution, under the cooperation of the limit groove and the limit block, the limiting effect of the slide groove on the slider is improved, thereby ensuring that the slider can reliably slide in the slide groove under the drive of the screw rod and realize the driving effect on the shell.

[0013] Optionally, the bottom of the housing is connected to the top of the slider via a rotating seat, the rotating seat is disposed at the center of the bottom of the housing, and the rotating seat can rotate around the rotating seat; A plurality of springs are provided between the bottom of the shell and the top of the slider, the springs supporting the shell and limiting the shell from being tilted, and the height of the shell facing the axis of the silo is lower than the height of the shell away from the axis of the silo.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] See also Figure 1-5 A silo intelligent spray dust suppression system includes an air compressor 4, an air tank 5 and a dry fog machine 6 which are connected in sequence through 8 pipelines. The air machine is used to transport and compress gas to the air tank 5. The air tank 5 is used to store gas and transport the compressed gas to the dry fog machine 6. A water tank 7 is also provided on the outside of the dry fog machine 6. The water tank 7 is also connected to the input end of the dry fog machine 6 through a pipeline 8 and is used to transport water to the dry fog machine 6. The output end of the dry fog machine 6 is connected to the spray mechanism 2 and transports dry fog into the spray mechanism 2. The spray mechanism 2 is arranged on the top of the silo 3. The dry fog is sprayed outward through the spray mechanism 2 and forms a dry fog layer on the top of the silo 3. The dry fog layer moves from top to bottom in the silo 3. In this process, it combines with the dust floating on the upper inner side of the silo 3 and falls to the bottom of the silo 3, thereby achieving a dust suppression effect. Furthermore, a sensor can be set on the top of the inner wall of the silo 3. When the sensor senses dust floating by, the signal is transmitted to the controller through a signal line, and the controller can control the start-up of the spray dust suppression system, thereby realizing automated and intelligent control to ensure timely and reliable dust suppression.

[0031] A base 1 is also provided on the top of the silo 3. The base 1 is annular. According to the different shapes of the silo 3, no less than four spray mechanisms 2 can be provided on the base 1. Each spray mechanism 2 includes a shell 21 and a plurality of spray heads 22. The plurality of spray heads 22 are arranged at intervals along the length direction of the shell 21. The output end of the dry fog machine 6 is connected to the shell 21. The dry fog generated by the dry fog machine 6 enters the shell 21 and is sprayed outward through the plurality of spray heads 22, thereby forming a dry fog layer. Since a plurality of spray mechanisms 2 are provided on the base 1, the plurality of spray heads 22 in the plurality of spray mechanisms 2 can spray dry fog from different directions toward the axial direction of the silo 3, effectively reducing the spray dead angle and improving the dust suppression effect.

[0032] A plurality of slide grooves 11 are also provided on the top of the base 1. The number and position of the slide grooves 11 are set corresponding to the housing 21, that is, when the housing 21 is placed, there is a slide groove 11 below the center of the bottom of each housing 21. A slider 12 is provided in the slide groove 11, two limit blocks 120 are symmetrically provided on the outer wall of the slider 12, and two limit grooves 110 are symmetrically provided on the inner wall of the slide groove 11. The length of the limit groove 110 can be the same as the length of the slide groove 11, and the length of the limit block 120 can be the same as the length of the slider 12, and the two sliders 12 are arranged in the two limit grooves 110 in a one-to-one correspondence. Furthermore, a screw rod 13 is passed through the slide groove 11, one end of the screw rod 13 is located on the inner side of the slide groove 11, and the other end of the screw rod 13 extends to the outside of the base 1. At the same time, the screw rod 13 passes through the middle part of the slider 12 and is connected to the slider 12 by a thread. A mounting seat 140 is provided on the outer wall of the base 1 or the outer wall of the silo 3, and a motor 14 is installed on the mounting seat 140. The output shaft of the motor 14 is connected to the screw rod 13, so that the motor 14 can drive the screw rod 13 to rotate.

[0033] Since the screw rod 13 and the slider 12 are in a threaded connection, when the motor 14 drives the screw rod 13 to rotate, the slider 12 can slide on the screw rod 13 under the limiting action of the limiting groove 110 and the limiting block 120, that is, the slider 12 can slide in the slide groove 11 along the length direction of the slide groove 11, and the housing 21 is arranged above the slider 12 and is mutually connected with the slider 12. When the slider 12 slides horizontally in the slide groove 11, the housing 21 can slide on the top of the base 1, thereby adjusting the position of the housing 21, and then adjusting the position of the spray head 22 on the housing 21. A plurality of housings 21 are arranged on the base 1, and each housing 21 can be adjusted separately. In this way, by controlling the speed and direction of the corresponding motor 14, the arrangement pattern of the plurality of spray heads 22 can be flexibly and automatically changed, thereby maximizing the coverage effect of the dry mist sprayed by the spray head 22 on the silo 3, avoiding the generation of spray dead angles, and significantly improving the dust suppression effect.

[0034] The bottom of the shell 21 is connected to the top of the slider 12 through a rotating seat 211. The rotating seat 211 is arranged at the bottom center of the shell 21. A plurality of springs 212 are also arranged between the bottom of the shell 21 and the top of the slider 12. The plurality of springs 212 are arranged at intervals along the length direction of the slider 12, and springs 212 are arranged on both sides of the rotating seat 211. In this way, in the absence of external force, the plurality of springs 212 can form a supporting effect on the shell 21. Further, by reasonably configuring the parameters of the springs 212 on both sides of the rotating seat 211, the shell 21 can be in an inclined state. Specifically, the height of the side of the shell 21 facing the axis of the silo 3 is lower than the height of the side of the shell 21 away from the axis of the silo 3. In this way, it is ensured that the dry mist sprayed by the spray head 22 can all enter the inner side of the silo 3, and the head-on collision of the dry mist sprayed by the two relatively arranged spray heads 22 is reduced, thereby ensuring that the particle size of the dry mist will not fluctuate greatly, thereby ensuring reliable suppression of dust in the silo 3. By setting a pad between the base 1 and the shell 21, the shell 21 can rotate around the rotating seat 211, so that the inclination angle of the shell 21 can be adjusted, making the angle adjustment of the spray head 22 more flexible. After removing the pad, the shell 21 can be quickly reset under the action of the elastic force of the spring 212.

[0035] A receiving groove 213 is provided at the bottom of the housing 21. Two clamping grooves 2133 are symmetrically provided on the inner wall of the receiving groove 213. Both the receiving groove 213 and the clamping groove 2133 extend along the length direction of the slide groove 11. The receiving groove 213 is located outside the slide groove 11. The length of the receiving groove 213 is less than or equal to the length of the slide groove 11. A sliding rod 2131 is provided in the receiving groove 213. One end of the sliding rod 2131 is inserted into one clamping groove 2133, and the other end of the sliding rod 2131 is inserted into the other clamping groove 2133. In this way, the sliding rod 2131 can be in a state of being always located in the receiving groove 213, and the end of the sliding rod 2131 can slide in the clamping groove 2133. A fixed seat 310 is provided on the outer wall of the silo 3, and an electric winding roller 31 is installed on the fixed seat 310. A traction rope 2132 is provided between the electric winding roller 31 and the slide bar 2131. One end of the traction rope 2132 is fixed and wound around the middle of the slide bar 2131, and the other end of the traction rope 2132 is wound around the electric winding roller 31.

[0036] Under the fixing action of the fixing seat 310, the electric winding roller 31 can reliably wind or release the traction rope 2132. Specifically, when the electric winding roller 31 rotates forward, the traction rope 2132 will be continuously wound toward the electric winding roller 31, and when the electric winding roller 31 rotates reversely, the traction rope 2132 will be continuously released from the electric winding roller 31. When the traction rope 2132 is continuously wound toward the electric winding roller 31, and the position of the electric winding roller 31 is in a relatively fixed state, the traction rope 2132 can pull the side of the housing 21 connected to the traction rope 2132 to rotate downward, thereby causing the housing 21 to gradually rotate from an inclined state to a horizontal state. When the traction rope 2132 is released from the electric winding roller 31, the overall length of the traction rope 2132 between the slide bar 2131 and the electric winding roller 31 will be expanded. At this time, under the action of the elastic force of the spring 212, the housing 21 can rotate around the rotating seat 211 again and return to the inclined state. By controlling the rotation direction of the electric winding roller 31, the shell 21 can be reliably rotated in the vertical direction, thereby achieving a wider range of adjustment of the angle of the spray head 22, ensuring that the dry mist sprayed from the spray head 22 can fully cover the top of the silo 3 without causing dead angles.

[0037] Furthermore, when the motor 14 drives the lead screw 13 to rotate, the lead screw 13 drives the slider 12 to slide, and the slider 12 drives the shell 21 to slide, since the traction rope 2132 always remains in a tensioned state, the traction rope 2132 can provide a certain pulling force to the slide bar 2131. In this way, when the shell 21 slips, under the pulling action of the traction rope 2132, the slide bar 2131 can remain in a relatively static state, and through the relative sliding of the slide bar 2131 in the slot 2133, the sliding of the shell 21 and the rotation of the shell 21 do not interfere with each other, which can maximize the adjustment effect of the shell 21 and the spray head 22, thereby ensuring that the best dust suppression effect can be achieved after the dry mist is sprayed.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
