Description

Technical Field

[0001] The invention relates to the technical field of chemical safety, and in particular to a dust suppression device for safe production of chemical industry. Background Art

[0002] Chemical workshops generate a lot of dust. In order to prevent dust from entering the respiratory tract, dust reduction equipment is often added to the workshop, such as dust reduction vehicles, dust reduction water pipes, and sprinkler trucks. The sprayed mist can dilute a large amount of dust in the air and drop it to the ground, thereby reducing the dust concentration. While wearing masks for production, the safety of the respiratory tract is further improved. In order to further improve the dust reduction effect, the dust reduction structure is also set on the workshop rolling door. By setting the dust reduction function in the door area, dust can be reduced from being discharged outside the workshop and causing environmental pollution.

[0003] From the above, it can be seen that the dust reduction function of the workshop door area is mostly set on the rolling doors of large workshops, and some workshop doors are often not limited to rolling doors. For example, the entry and exit doors of small workshops or warehouses are rotary opening and closing types. Although the workshop or warehouse environment is small, the dust concentration generated by chemical products is greater, which will also pose a threat to the respiratory tract or the environment when entering and exiting, and the dust will change with the opening and closing status of the door. For example, when the door is closed, the dust adheres to the door, and when the door is opened, the dust will enter the human body at the first time.

DETAILED DESCRIPTION

[0025] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0026] In one embodiment, Figure 1-Figure 9 As shown:

[0027] The present embodiment provides a dust suppression device for chemical production safety, including a door frame 1, on which a workshop door 11 is installed, which can be a single or double workshop door 11, and a positioning frame 2 is respectively provided on the left and right sides of the inner surface of the door frame 1, the top of the positioning frame 2 reaches the top of the door frame 1, and the bottom of the positioning frame 2 reaches the bottom of the door frame 1, the positioning frame 2 on the left side is provided with a slot 3 opening to the left, and the positioning frame 2 on the right side is provided with a slot 3 opening to the right, and a water pipe 4 is provided in the slot 3, and a water tank 5 is provided on one side of the door frame 1, and the water inlet end of the water pipe 4 is connected to the water tank 5 and water is supplied to the water pipe 4 by a water pump 20, and the upper part of the water pipe 4 spans from one side of the door frame 1 to the other side of the door frame 1 along the top of the door frame 1, and the cross section 41 above the water pipe 4 can rotate, and a plurality of nozzles 6 extending inward are provided on the cross section 41, and the extended end of the nozzle 6 is bent upward for a length and then bent downward, so that the atomizing nozzle 7 on its nozzle As it tilts downward, above the first transmission shaft 9, several nozzles 6 are evenly distributed along the length direction of the cross section 41, and each nozzle 6 is equipped with an atomizing nozzle 7. A bearing seat 8 is installed on the inner surface of the positioning frame 2, and a first transmission shaft 9 is installed on the bearing seat 8. A first gear 10 is installed on the first transmission shaft 9, and a second gear 42 is installed on the cross section 41. The first gear 10 is meshed with the second gear 42. The first transmission shaft 9 is parallel to the inner side of the cross section 41, and the atomizing nozzle 7 is located above the first transmission shaft 9. When the first transmission shaft 9 rotates, the first gear 10 meshes with the second gear 42 to rotate, and the cross section 41 is driven by the second gear 42 to rotate, and the atomizing nozzle 7 is driven by the cross section 41 to switch the dust reduction to the inner surface of the workshop door 11 and the workshop. The door frame 1 is provided with a driving component 12 that can control the forward and reverse rotation of the first transmission shaft 9 when the workshop door 11 is opened and closed.

[0028] like Figure 2 As shown, the door frame 1 is provided with a plurality of fixing holes 13, which are evenly distributed according to the shape of the door frame 1. The door frame 1 and the components on the door frame 1 are installed in a workshop or warehouse by driving screws into the fixing holes 13. In addition, in order to prevent the top drive assembly 12 from causing obstacles during installation, a hanger 26 is connected to the top of the door frame 1 through the fixing holes 13. The top height of the hanger 26 is higher than the drive assembly 12. The hanger 26 is provided with an assembly hole 27. The top of the door frame 1 is fixed to the building through the assembly hole 27 and the hanger 26.

[0029] like Figure 7 , Figure 8As shown, a set of pipe joints 23 are respectively provided on the left and right sides above the water pipe 4, and the left and right ends of the cross section 41 are transferred to the left and right sides above the water pipe 4 through the left and right pipe joints 23, so that the cross section 41 can rotate independently relative to the water pipe 4, and a slot 24 is respectively provided on the top of the left and right positioning frames 2, and the two slots 24 are communicated with the notch 3, and the left and right ends of the cross section 41 pass through the left and right slots 24, and the two slots 24 are provided with bearings 25 assembled on the left and right ends of the cross section 41. The water pipe 4 is arranged according to the notch 3 of the left and right positioning frames 2. This installation method allows the water pipe 4 to be reasonably stored, and only the cross section 41 above the water pipe 4 is retained to be rotatable. In this way, when the water pump 20 supplies water to the water pipe 4, the atomizing nozzle 7 above is swung by the cross section 41, which can enlarge the spray range of the atomizing nozzle 7, thereby improving the dust reduction effect.

[0030] like Figures 4 to 9 As shown, a door shaft 14 is installed in the door frame 1, one side of the workshop door 11 is connected to the door shaft 14, and when the workshop door 11 is opened and closed, it can drive the door shaft 14 to rotate. The driving assembly 12 includes a second bearing seat 15 fixed to the upper inner surface of the positioning frame 2, and a second transmission shaft 16 is installed on the second bearing seat 15. The second transmission shaft 16 is vertically located near the first transmission shaft 9. The driving assembly 12 also includes a bevel gear structure 17 installed between the second transmission shaft 16 and the first transmission shaft 9 and meshed with each other. The top of the door shaft 14 reaches above the door frame 1. The driving assembly 12 also includes a driving wheel 18 installed at the top of the door shaft 14 and a driven wheel 19 installed at the top of the second transmission shaft 16. The driving wheel 18 and the driven wheel 19 are connected by a conveyor belt 21. When the workshop door 11 is opened and closed, the workshop door 11 will rotate with the door shaft 14, the door shaft 14 will rotate with the driving wheel 18, the driving wheel 18 will rotate with the driven wheel 19, the driven wheel 19 will rotate with the second transmission shaft 16, the second transmission shaft 16 will mesh with the bevel gear structure 17, and transmit the transmission force to the first transmission shaft 9, the first transmission shaft 9 will rotate with the first gear 10, the first gear 10 will rotate with the second gear 42, the second gear 42 will rotate with the cross section 41, and the cross section 41 will complete the automatic swinging action with the atomizing nozzle 7. It can be seen that if you want to change the spray range of the atomizing nozzle 7, you only need to control the rotation amplitude of the workshop door 11, which can be completed by using the opening and closing structure of the workshop door 11 itself. No additional power mechanism is required.

[0031] Working principle and effect: Figures 1 to 9As shown, when the workshop door 11 is opened outward, it will rotate with the door shaft 14, and the door shaft 14 will rotate the driving wheel 18 counterclockwise, and the driving wheel 18 will rotate counterclockwise with the driven wheel 19 through the conveyor belt 21, and the driven wheel 19 will rotate the second transmission shaft 16 counterclockwise, and the second transmission shaft 16 will rotate with the bevel gear structure 17, and the first transmission shaft 9 will rotate counterclockwise, and the first transmission shaft 9 will rotate with the second gear 42 clockwise, and the second gear 42 will rotate the cross section 41 above the water pipe 4 clockwise separately. The clockwise rotation causes all the nozzles 6 above to deflect upward with the atomizing nozzles 7 to an upward position. At this time, the spray direction of the atomizing nozzles 7 will be toward the workshop, that is, when the workshop door 11 is opened, the atomizing nozzles 7 will be aimed at the workshop for atomization treatment, so that the dust still attached to the air during the previous construction in the workshop will be treated by dust reduction. Therefore, each time the workshop door 11 is opened, the dust in the workshop will be reduced in advance to reduce the possibility of dust entering the respiratory tract, especially in heavy chemical storage, which provides protection for human safety. On the contrary, when the workshop door 11 is closed inward, the door shaft 14 rotates in the opposite direction, and the door shaft 14 drives the driving wheel 18 to rotate clockwise, and the driving wheel 18 drives the driven wheel 19 to rotate clockwise through the conveyor belt 21, and the driven wheel 19 drives the second transmission shaft 16 to rotate clockwise, and the second transmission shaft 16 drives the bevel gear structure 17 to mesh and rotate, and the first transmission shaft 9 rotates clockwise, and the first transmission shaft 9 drives the second gear 42 to rotate counterclockwise, and the second gear 42 drives the cross section 41 above the water pipe 4 to rotate counterclockwise alone, so that all the nozzles 6 above deflect downward with the atomizing nozzle 7. At this time, the spray direction of the atomizing nozzle 7 is close to the inner surface of the workshop door 11. As the workshop door 1 is completely closed, the spray direction of the atomizing nozzle 7 will directly face the inner surface of the workshop door 11. At this time, the atomizing nozzle 7 sprays water vapor and directly acts on the inner surface of the workshop door 11, so that the dust on the workshop door 11 is completely removed and cleaned. Whether it is the dust reduction treatment inside the workshop or on the inner surface of the workshop door 11, workers do not need to pay extra labor, they only need to open and close the door habitually.

[0032] In another embodiment, the water pump 20 is installed on the pipeline of the water pipe 4, and an electric control box is installed on the water tank 5. At least a timing module and a controller for controlling the working time of the water pump 20 are installed in the electric control box. A contact switch and a distance switch are provided on the door frame 1. When the workshop door 11 is closed, the contact switch is touched, and the contact switch controls the water pump 20 to be powered on. For example, after the timer counts for 20 minutes, the contact switch automatically cuts off the power, the water pump 20 stops working, and the atomization work is completed. When the workshop door 11 is opened to a certain angle, the distance switch controls the water pump 20 to be powered on. For example, after the timer counts for 20 minutes, the distance switch automatically cuts off the power, the water pump 20 stops working, and the atomization work is completed. The purpose of intelligent atomization injection is achieved.

[0033] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.
