Description

Technical Field

[0001] The invention relates to the technical field of dust removal, and in particular to an atomizing foam type dust removal device. Background Art

[0002] In the process of sand and gravel production, it is usually necessary to use a conveying device to convey the sand and gravel to different processing devices in sequence. When transferring the sand and gravel to the processing device, the sand and gravel are usually thrown into the conveyor attached to the processing device. However, when the sand and gravel are thrown from the conveying device to the conveyor of the processing device, the sand and gravel collide with the conveyor, causing the smoke and dust carried by the sand and gravel to be raised, resulting in a large amount of smoke and dust at the transfer point (i.e., the connection point between the conveying device and the conveyor), which is harmful to the health of nearby workers. At present, an atomizing foam type dust removal device is usually set above the transfer point. When the sand and gravel are transported to the transfer point and thrown out, the atomizing foam type dust removal device The dust removal device is started and sprays atomized foam to deal with the raised smoke and dust. However, due to the different production speeds of different types of sand and gravel, the speed of a single production of sand and gravel is not fixed. In order to increase the service life of the conveyor, when the speed of producing sand and gravel is fast, the conveying speed of the conveyor is usually increased to prevent the conveyor from being "overloaded" and causing irreversible damage to the conveyor. Therefore, the conveying speed of the conveyor is not fixed, that is, the horizontal distance at which the sand and gravel are thrown each time is uncertain, making it difficult for the existing atomized foam dust removal device to face the position where the sand and gravel collide with the conveyor, that is, the sprayed foam cannot face the area where smoke and dust are generated, resulting in low dust removal efficiency.

DETAILED DESCRIPTION

[0026] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on the present invention. In order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of actual products. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0027] Since the speed at which the conveyor transports sand and gravel is not fixed, that is, the horizontal distance at which the sand and gravel are thrown each time is uncertain, it is difficult for the existing atomizing foam dust removal device to directly face the position where the sand and gravel collide with the conveyor (the conveying device and conveyor in this article are both belt conveyors), resulting in low dust removal efficiency.

[0028] Example 1: Atomizing foam type dust removal device, please refer to Figure 1-Figure 3, including a dust removal shell 1, a main conveyor belt 2 is installed on the upper part of the right side of the dust removal shell 1, and an auxiliary conveyor belt 3 is installed on the lower part of the left side of the dust removal shell 1. Two hydraulic cylinders 4 symmetrically distributed front and back are fixedly connected to the lower part of the dust removal shell 1, and a friction rod 5 is limitedly slidably connected in the hydraulic cylinder 4. Two mounting plates 6 symmetrically distributed front and back are limitedly slidably connected in the dust removal shell 1, and the mounting plates 6 are fixedly connected to adjacent friction rods 5. Four equidistant nozzles 7 are equidistantly connected to the opposite sides of the symmetrically distributed mounting plates 6 by limited sliding on the left and right. Infusion pipes 8 are fixedly connected to the front and rear sides of the dust removal shell 1, and the infusion pipes 8 are connected to the external conveying device for conveying foam liquid through flanges. The four equidistant nozzles 7 on the same mounting plate 6 are connected to the adjacent infusion pipes 8 through conduits.

[0029] Please refer to Figure 2-Figure 4 Two sealing rings 9 symmetrically distributed front and back are fixedly connected to the upper part of the dust removal shell 1, and a detection member 10 is sealed and rotatably connected inside the sealing ring 9. The detection member 10 is spline-connected to the rotating shaft on the left side of the main conveyor belt 2. Two symmetrically distributed extrusion chambers 101 are arranged in the detection member 10, and a weight block 11 is limited and sealed and slidably connected in the extrusion chamber 101. A sliding member 12 is limited and sealed and slidably connected in the detection member 10 at a position away from the main conveyor belt 2. The side of the sliding member 12 close to the main conveyor belt 2 cooperates with the adjacent detection member 10 to form a transmission chamber 121. The detection member 10 is provided with first through holes symmetrically distributed, and the first The through hole connects the adjacent extrusion chamber 101 with the adjacent transmission chamber 121, and a transfer piece 13 is fixedly connected to the side of the sealing ring 9 away from the main conveyor belt 2. The transfer piece 13 is sealed and slidably connected to the adjacent sliding piece 12, and the transfer piece 13 is sealed and rotatably connected to the adjacent detection piece 10. The sliding piece 12 is limitedly and slidably connected to the adjacent transfer piece 13. The detection piece 10, the adjacent sliding piece 12 and the adjacent transfer piece 13 cooperate to form an adjusting chamber 131. The left side of the hydraulic cylinder 4 is connected to the adjacent adjusting chamber 131 through a conduit. Hydraulic oil is stored in the extrusion chamber 101, the transmission chamber 121, the adjusting chamber 131 and the adjacent conduit.

[0030] Please refer to Figure 4 and Figure 5The mounting plate 6 is provided with three width-adjusting telescopic rods 14 in a linear array, and the three width-adjusting telescopic rods 14 in the linear array are staggeredly distributed with four adjacent and equidistant nozzles 7, and the telescopic end and the fixed end of the width-adjusting telescopic rod 14 are respectively fixedly connected with two adjacent nozzles 7, and a telescopic tube 15 is fixedly connected to the lower part of the mounting plate 6, and the width-adjusting telescopic rod 14 is connected with the adjacent telescopic tubes 15, and a spring is provided between the telescopic part and the fixed part in the width-adjusting telescopic rod 14, and in the direction from right to left, the elastic coefficients of the above three springs are gradually reduced in an arithmetic progression. In the direction from right to left, the distance between adjacent nozzles 7 gradually increases, thereby improving the dust removal effect at different positions in the sand and gravel. The sealing ring 9 cooperates with the adjacent detection member 10 to form a transfer chamber 151. The detection member 10 is provided with two symmetrically distributed second through holes, which connect the adjacent extrusion chamber 101 with the adjacent transfer chamber 151. The left end of the telescopic tube 15 is connected with the adjacent transfer chamber 151 through a conduit. Hydraulic oil is stored in the telescopic tube 15, the width-adjustable telescopic rod 14, the transfer chamber 151 and the adjacent conduit.

[0031] Please refer to Figure 4 and Figure 6 A threaded tube 16 is fixedly connected to the side of the transfer member 13 away from the adjacent sealing ring 9 , an adjusting ring 17 is threadedly connected to the threaded tube 16 , and an initially compressed spring is arranged between the side of the adjusting ring 17 away from the adjacent sealing ring 9 and the adjacent sliding member 12 .

[0032] Please refer to Figure 3 and Figure 7 The right part of the hydraulic cylinder 4 is sealed and slidably connected with a piston 18, and a tension spring is fixedly connected between the right side of the piston 18 and the adjacent friction rod 5. The left side of the piston 18 cooperates with the adjacent hydraulic cylinder 4 to form a buffer chamber 181. Hydraulic oil is stored in the buffer chamber 181. The buffer chamber 181 is connected with the adjacent regulating chamber 131 through the conduit of the adjacent hydraulic cylinder 4. The hydraulic cylinder 4 and the adjacent friction rod 5 are frictionally matched, so that there is a time difference between the movement of the friction rod 5 and the adjacent piston 18, and this time difference is equal to the time required for the sand and gravel to fall from the main conveyor belt 2 to the auxiliary conveyor belt 3.

[0033] When the conveyor belt is used to transport sand and gravel, the sand and gravel move from right to left on the main conveyor belt 2 and finally enter the dust removal shell 1. Then the sand and gravel lose contact with the main conveyor belt 2 and fall freely to the upper side of the auxiliary conveyor belt 3. Then the sand and gravel continue to move left following the auxiliary conveyor belt 3. When the main conveyor belt 2 transports sand and gravel, the main conveyor belt 2 drives the two detection parts 10 to rotate counterclockwise (the rotation perspective in this article is from front to back) through the spline (the parts on the front side of the dust removal shell 1 will be used for explanation later), and the detection part 10 drives the two weights 11 therein to rotate. The block 11 is moved in the direction away from the rotation axis of the detection member 10 by the centrifugal force, and the hydraulic oil in the adjacent extrusion chamber 101 is squeezed into the transfer chamber 151 through the adjacent second through hole. At the same time, the detection member 10 draws the hydraulic oil in the transmission chamber 121 into the adjacent extrusion chamber 101 through the adjacent first through hole. The hydraulic oil in the transmission chamber 121 drives the sliding member 12 to move backward, compresses the spring between the sliding member 12 and the adjacent adjustment ring 17, and at the same time increases the volume of the adjustment chamber 131, and draws out the hydraulic oil in the buffer chamber 181 through the adjacent conduit.

[0034] As the hydraulic oil in the buffer chamber 181 is pumped out, the piston 18 moves to the left, and at the same time, the tension spring adjacent to the right side of the piston 18 is stretched. The tension spring pulls the friction rod 5 to slowly move to the left, and the friction rod 5 drives the mounting plate 6 to move, and the mounting plate 6 drives the nozzle 7 thereon to move. Subsequently, the four nozzles 7 spray atomized foam at the same time to clean up the dust generated by the impact of sand and gravel at the transfer point. By changing the initial position of the nozzle 7, the four nozzles 7 are made to face the position where the sand and gravel collide with the auxiliary conveyor belt 3, thereby improving the dust removal effect.

[0035] When the gravel loses contact with the main conveyor belt 2, the particles and slag in the gravel are thrown to the left together. The slag is looser than the particles and contains a large number of gaps inside, which makes the overall mass distribution of the slag uneven and the stability poor. Therefore, the slag is more susceptible to air resistance and gravity when in the air, resulting in the horizontal distance of the slag moving being shorter than the horizontal distance of the particles. At the same time, as the speed of the main conveyor belt 2 increases, the difference in the horizontal distances moved by the particles and the slag will increase, that is, the area covered by the gravel on the auxiliary conveyor belt 3 gradually increases, and it is necessary to increase the area that the nozzle 7 can cover. The specific operation is as follows: When the hydraulic oil in the extrusion chamber 101 is squeezed into the transfer chamber 151 through the adjacent second through hole, the excess hydraulic oil in the transfer chamber 151 enters the telescopic tube 15 through the adjacent conduit, and then the hydraulic The oil enters the three width-adjusting telescopic rods 14, causing the telescopic ends of the width-adjusting telescopic rods 14 to extend, and the telescopic ends of the width-adjusting telescopic rods 14 drive the adjacent nozzles 7 to move left, increasing the distance between the two adjacent nozzles 7 and compressing the springs in the width-adjusting telescopic rods 14, thereby expanding the range that the foam sprayed by the nozzles 7 can cover. At the same time, since the slag is more likely to generate smoke and dust, the amount of foam sprayed onto the slag should be greater than the amount of foam sprayed onto the particles. The specific operation is as follows: Since the elastic coefficients of the springs in the three width-adjusting telescopic rods 14 are different, the lengths of the telescopic ends of the three width-adjusting telescopic rods 14 extending from right to left increase successively, thereby gradually increasing the distance between the two adjacent nozzles 7 in the direction from right to left, thereby achieving an effect that the amount of foam sprayed onto the slag is greater than the amount of foam sprayed onto the particles, which is convenient for processing the smoke and dust overflowing from the sand and gravel slag.

[0036] Before using the conveyor belt to transport sand and gravel, the worker adjusts the adjustment ring 17 according to the vertical distance between the upper side of the main conveyor belt 2 and the auxiliary conveyor belt 3. If the above distance is large, that is, the sand and gravel have a long time to fall freely after losing contact with the main conveyor belt 2, which makes the sand and gravel move a long horizontal distance. At this time, the worker rotates the adjustment ring 17 to move the adjustment ring 17 backward, and the initial compression of the spring between the adjustment ring 17 and the adjacent sliding member 12 is reduced, so that the distance that the subsequent weight block 11 can move when subjected to the same centrifugal force is increased, thereby increasing the distance that the nozzle 7 moves to the left, so that the nozzle 7 is directly opposite to the contact point between the sand and gravel and the auxiliary conveyor belt 3.

[0037] When the conveying of sand and gravel stops, the main conveyor belt 2 and the auxiliary conveyor belt 3 both stop. At this time, the weight 11 is no longer affected by the centrifugal force. The sliding member 12 moves forward and resets under the action of the adjacent spring. At the same time, the hydraulic oil in the adjusting chamber 131 is squeezed into the buffer chamber 181 through the adjacent conduit. The hydraulic oil in the buffer chamber 181 drives the piston 18 to move right and reset. The piston 18 pushes the friction rod 5 to reset through the tension spring. The friction rod 5 drives the mounting plate 6 to reset. At the same time, the transmission chamber 121 re-extracts the hydraulic oil entering the two extrusion chambers 101 through the two first through holes, so that the two weights 11 are reset relative to the detection member 10. The extrusion chamber 101 draws back the hydraulic oil in the transfer chamber 151 through the adjacent second through hole. The transfer chamber 151 draws back the hydraulic oil in the three width-adjusting telescopic rods 14 through the adjacent conduit and the telescopic tube 15, so that the telescopic end of the width-adjusting telescopic rod 14 contracts, and the telescopic end of the width-adjusting telescopic rod 14 drives the adjacent nozzle 7 to move right and reset.

[0038] When using a conveyor belt to transport sand and gravel, the existing dust removal device will start the dust removal device when the conveyor belt is started. However, the sand and gravel have not moved to the transfer point at the beginning. At this time, spraying foam will waste foam liquid and bring unnecessary economic losses.

[0039] Example 2: Based on Example 1, please refer to Figure 1 , Figure 2 and Figure 8 , and also includes a rotating shaft 19, which is rotatably connected to the upper part of the dust removal shell 1, and a torsion spring is fixedly connected between the rotating shaft 19 and the dust removal shell 1. The lower sides of the rotating shaft 19 and the dust removal shell 1 are fixedly connected with equidistant dust curtains 20. Initially, the lower side of the dust curtain 20 contacts the upper side of the main conveyor belt 2 or the auxiliary conveyor belt 3, and the main conveyor belt 2 and the auxiliary conveyor belt 3 are respectively in contact with the adjacent dust curtains 20 to prevent the smoke generated at the transfer point from spreading.

[0040] Please refer to Figure 8 Two arc-shaped telescopic rods 21 symmetrically distributed front and back are fixedly connected to the upper right part of the dust removal shell 1. The telescopic ends of the arc-shaped telescopic rods 21 are fixedly connected to the rotating shaft 19, and the rotation center of the arc-shaped telescopic rods 21 is located on the rotation axis of the rotating shaft 19, which is used to monitor the rotation of the rotating shaft 19.

[0041] Please refer to Figure 8 and Fig. 9 A blocking telescopic rod 22 is fixedly connected to the right side of the infusion tube 8. The telescopic end of the blocking telescopic rod 22 passes through the adjacent infusion tube 8 and is fixedly connected to a blocking piece 23. The blocking piece 23 is sealingly and slidingly connected to the adjacent infusion tube 8. The blocking piece 23 cooperates with the adjacent infusion tube 8 to block. Initially, the blocking piece 23 blocks the adjacent infusion tube 8. The blocking telescopic rod 22 is connected to the adjacent arc-shaped telescopic rod 21 through a conduit. Hydraulic oil is stored in the blocking telescopic rod 22 and the adjacent conduit.

[0042] Please refer to Fig.10 A baffle plate 24 is fixedly connected to the lower part of the dust removal shell 1. The baffle plate 24 is placed obliquely relative to the horizontal plane, and the height of the baffle plate 24 gradually decreases from right to left. The lowest point of the baffle plate 24 is coplanar with the highest point on the right side of the auxiliary conveyor belt 3, so as to guide the sand and gravel rolling to the right side of the auxiliary conveyor belt 3 to fall back onto the auxiliary conveyor belt 3.

[0043] When conveying sand and gravel, after the main conveyor belt 2 and the auxiliary conveyor belt 3 are started, the steps in Example 1 are repeated to adjust the initial position of the nozzle 7. Subsequently, after the sand and gravel come into contact with the dust-proof curtain 20, the dust-proof curtain 20 is subjected to the friction force of the sand and gravel, so that the dust-proof curtain 20 pulls the rotating shaft 19 to rotate clockwise and twists the torsion spring adjacent to the rotating shaft 19. The rotating shaft 19 drives the telescopic end of the arc-shaped telescopic rod 21 to extend, and the arc-shaped telescopic rod 21 extracts the hydraulic oil in the blocking telescopic rod 22 through the adjacent conduit, so that the telescopic end of the blocking telescopic rod 22 drives the blocking member 23 to move, and the blocking member 23 gradually releases the blockage of the infusion pipe 8, and the foam liquid enters the four nozzles 7 through the infusion pipe 8 and is sprayed out. The friction force of the sand and gravel on the upper dust-proof curtain 20 controls the flow of the foam liquid through the infusion pipe 8, thereby changing the pressure of the foam liquid at the nozzle 7 to prevent the occurrence of excessive or insufficient foam liquid, while improving the utilization rate of the foam liquid.

[0044] When sand and gravel fall from the main conveyor belt 2 to the auxiliary conveyor belt 3, the impact between the sand and gravel and the auxiliary conveyor belt 3 causes the sand and gravel to splash, which can easily cause the sand and gravel to fall to the ground. In order to reduce the probability of sand and gravel falling to the ground, the specific operation is as follows: when the sand and gravel splash to the right side of the auxiliary conveyor belt 3, the sand and gravel contact the baffle plate 24, and then under the guidance of the baffle plate 24, the sand and gravel roll back to the upper side of the auxiliary conveyor belt 3, thereby reducing the probability of sand and gravel falling to the ground.

[0045] When the sand and gravel are transported, the upper dust curtain 20 loses the friction force of the sand and gravel, and the rotating shaft 19 rotates counterclockwise and resets under the action of its adjacent torsion spring. The rotating shaft 19 drives the telescopic end of the arc-shaped telescopic rod 21 to contract and reset, and the hydraulic oil in the arc-shaped telescopic rod 21 is squeezed into the blocking telescopic rod 22 through the adjacent conduit. The telescopic end of the blocking telescopic rod 22 drives the blocking member 23 to re-block the infusion tube 8.

[0046] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present application, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of this application.
