Description

Technical Field

[0001] This utility model relates to the field of dust suppression device technology, and more specifically, to a dust suppression device for safe production. Background Technology

[0002] To prevent explosions in industrial production: When dust reaches a certain concentration in the air, it may explode upon contact with an open flame or other heat source, especially in environments involving combustible dust, such as coal mines. The concentration range for coal dust explosions is generally 30-50 g / m³. 3 Up to 1000-2000g / m 3 The concentration range with the strongest explosive force is 300-500 g / m3. Therefore, dust suppression can effectively reduce dust concentration and reduce the risk of explosion.

[0003] Patent publication number CN222219037U discloses a dust suppression device for chemical safety production, including a mounting base. A rotating shaft is rotatably connected through the top of the mounting base. A rotating motor located on one side of the rotating shaft is fixedly installed inside the mounting base. The output end of the rotating motor is connected to the rotating shaft for transmission. Swing seats are symmetrically fixedly installed on both sides of the top of the rotating shaft. A swing motor is fixedly installed inside the rotating shaft. An atomizing nozzle is rotatably connected to the top of the swing seat. A sliding seat located below the atomizing nozzle is integrally set inside the swing seat. By setting up the swing motor, the swing motor drives the half gear to rotate, so that the half gear meshes with two reciprocating racks in sequence, thereby driving the sliding plate to move back and forth along the sliding seat. This causes the half-tooth ring meshing with the reciprocating racks to drive the atomizing nozzle to swing back and forth, thereby increasing the spray range of water mist and increasing the dust removal range.

[0004] However, the atomizing nozzle in patent publication number CN222219037U can only swing in one direction, which to some extent reduces the dust suppression range. In order to further improve the dust suppression range and the dust suppression effect, we propose a dust suppression device for safe production to solve the above-mentioned problems.

[0020] 3. Beneficial effects

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figure 1-4A dust suppression device for safe production includes a movable base 1, and a driven gear 2 is rotatably connected to the middle of the upper surface of the movable base 1.

[0033] The upper surface edge of the movable base 1 is rotatably connected to the drive gear 3, which meshes with the driven gear 2, and the lower surface edge of the movable base 1 is equipped with a servo motor 6 whose power output end is connected to the drive gear 3.

[0034] A bracket 7 is fixedly connected to the edge of the upper surface of the driven gear 2. Multiple sets of brackets 7 are arranged in the radial position of the driven gear 2, and two brackets 7 are symmetrically arranged in each set.

[0035] Atomizing nozzles 8 are rotatably connected between the top ends of the two brackets 7 in each group. A connecting frame 10 with a U-shaped structure is fixedly connected to the end of the atomizing nozzle 8. An electric telescopic rod 12 is installed in the middle of the upper surface of the driven gear 2. A connecting seat 13 is installed at the movable end of the electric telescopic rod 12. A notch is opened in the connecting seat 13 corresponding to the part of the atomizing nozzle 8. A connecting shaft 14 is fixedly connected to the inner side of the notch. A connecting rod 15 is installed between the connecting shaft 14 and the connecting frame 10. The two ends of the connecting rod 15 are rotatably connected to the connecting shaft 14 and the connecting frame 10, respectively.

[0036] It should be noted that the device is moved to the designated dust suppression location in the production area using the mobile base 1. Water is supplied to the atomizing nozzles 8 using a water pump. First, the movable end of the electric telescopic rod 12 is controlled to reciprocate within a certain range. The two ends of the connecting rod 15 are respectively coordinated with the connecting frame 10 and the connecting shaft 14 to swing, thereby causing the water spray end of the atomizing nozzles 8 to swing up and down. Using multiple atomizing nozzles 8 can effectively increase the dust suppression range. By setting a suitable forward and reverse rotation program for the servo motor 6, the power output end of the servo motor 6 drives the drive gear 3 to rotate, which in turn drives the driven gear 2 to rotate. After the driven gear 2 rotates 180°, it rotates in the opposite direction through the power output end of the servo motor 6, and so on, which can further increase the dust suppression range of the atomizing nozzles 8, improve the dust suppression effect, effectively reduce dust concentration, reduce the risk of explosion, and ensure safe production.

[0037] like Figure 1 , Figure 3 As shown, a first connecting shaft 4 is welded to the middle of the lower surface of the driven gear 2, and the first connecting shaft 4 is connected to the movable base 1 through a bearing;

[0038] It should be noted that this reduces the friction between the first connecting shaft 4 and the movable base 1, and ensures the rotational accuracy of the driven gear 2.

[0039] like Figure 1 , Figure 4As shown, a second connecting shaft 5 that penetrates the movable base 1 is welded to the middle of the lower surface of the drive gear 3, and the second connecting shaft 5 is connected to the movable base 1 through a bearing;

[0040] The power output end of the servo motor 6 is connected to the second connecting shaft 5 via a coupling;

[0041] It should be noted that this reduces the friction between the second connecting shaft 5 and the moving base 1, while ensuring the rotational accuracy of the drive gear 3 and ensuring that the power of the servo motor 6 can be transmitted normally to the drive gear 3.

[0042] like Figure 1 , Figure 2 As shown, the bracket 7 is specifically set in three groups, and the angle between the corresponding driven gear 2 axis of each group of bracket 7 is 120°. The outer wall of the atomizing nozzle 8 is symmetrically fixed with a shaft head 9, and the shaft head 9 is connected to the top of the bracket 7 through a bearing.

[0043] It should be noted that the resistance of the atomizing nozzle 8 during rotation is reduced.

[0044] like Figure 2 As shown, a flexible hose 11 is installed at the water inlet end of the atomizing nozzle 8;

[0045] It should be noted that after the hose 11 is connected to the four-way connector, the water pump is connected to the four-way connector to deliver water to the atomizing nozzle 8.

[0046] like Figure 1 As shown, a control host 16 is installed on one side of the drive gear 3, and the output end of the control host 16 is electrically connected to the input end of the servo motor 6 and the electric telescopic rod 12.

[0047] It should be noted that the reciprocating motion of the movable end of the electric telescopic rod 12 is controlled by the control host 16, and a suitable forward and reverse rotation program is set for the servo motor 6 by the control host 16.

[0048] In use: The device is moved to the designated dust suppression location in the production area using the mobile base 1. Water is supplied to the atomizing nozzles 8 using a water pump. First, the movable end of the electric telescopic rod 12 is controlled to reciprocate within a certain range. The two ends of the connecting rod 15 are respectively coordinated with the connecting frame 10 and the connecting shaft 14 to swing, thereby causing the water spray end of the atomizing nozzles 8 to swing up and down. Using multiple atomizing nozzles 8 can effectively increase the dust suppression range. By setting a suitable forward and reverse rotation program for the servo motor 6, the power output end of the servo motor 6 drives the drive gear 3 to rotate, which in turn drives the driven gear 2 to rotate. After the driven gear 2 rotates 180°, it rotates in the opposite direction through the power output end of the servo motor 6, and so on, which can further increase the dust suppression range of the atomizing nozzles 8, improve the dust suppression effect, effectively reduce dust concentration, reduce the risk of explosion, and ensure safe production.

[0049] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
