Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression devices, in particular to a dust suppression device for construction engineering. Background Art

[0002] With the modernization of cities, the construction industry is also developing continuously. In the early stage of construction, after the earthwork, the road surface of the construction site is all earth road surface. During the construction, the construction equipment will raise a lot of dust, which will affect the health of the construction workers and the surrounding residents. Therefore, dust reduction devices are needed to reduce dust during the construction process. In the existing technology, most construction projects use fog guns for dust reduction. The fog gun is commonly known as a fog cannon, which is composed of a wind tube, a motor, a fan blade, an upper bracket, a base, a water pump, a pitch mechanism, a nozzle assembly, an electrical control system and other main components.

[0003] After the construction of the existing mist shooter is completed, the equipment will be shut down. When the equipment is shut down, there are still a lot of water stains on the equipment nozzle, and there is still a lot of dust in the surrounding air, which causes the nozzle to absorb dust. When the water evaporates, the dust forms mud blocks to block the nozzle, thereby affecting the spray range of the mist shooter and the dust reduction effect. Therefore, a dust reduction device for construction engineering is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a dust suppression device for construction engineering, which has the advantage of anti-clogging and solves the problem that the nozzle of the dust suppression device for construction engineering in the prior art is easily clogged.

[0009] As a preferred embodiment of the dust suppression device for construction engineering of the utility model, the number of the buckles is two, and the center distance between the slots on the two groups of buckles is equal to half of the distance between adjacent nozzles.

[0010] As a preferred dust suppression device for construction engineering of the utility model, a pressure relief plug is arranged at the center of the baffle, the pressure relief plug is a cylindrical rubber plug, a pressure relief hole is arranged at the center of the pressure relief plug, and the pressure relief hole is a conical through hole.

[0012] As a preferred embodiment of the dust suppression device for construction engineering of the utility model, a dustproof plate is provided on the top of the front end surface of the outer sleeve ring.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model sets a dustproof mechanism at the front end of the nozzle, so that after the sprayer is used, the baffle of the dustproof mechanism covers the nozzle, and cooperates with the dustproof plate structure on the outer ring to prevent the water stains remaining on the nozzle from absorbing dust and causing the nozzle to be blocked, thereby improving the dust removal stability of the equipment.

DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 5 A dust suppression device for construction engineering includes a mist shooter body 1, the mist shooter body 1 includes a water supply box 101, a mist cannon barrel 102, a fan 103 and a nozzle 14, and a dust prevention mechanism 2 is arranged at the front end of the nozzle 14;

[0023] The dustproof mechanism 2 includes an outer ring 220 and an inner ring 210. The outer ring 220 is fixedly mounted on the front end of the fog cannon barrel 102. The inner ring 210 is rotatably connected to the outer ring 220 via a bearing. The inner ring 210 is provided with a baffle 211 corresponding to the number and position of the nozzles 14.

[0024] When the device is in use, first, the position of the baffle 211 is adjusted by the handle 212 so that the baffle 211 and the nozzle 14 are offset, so that the nozzle 14 can perform spray dust removal. When the dust removal is completed, the device is turned off and the handle 212 is reset so that the baffle 211 covers the nozzle 14, thereby preventing dust in the air from falling into the nozzle 14 and causing the nozzle 14 to be blocked.

[0025] Furthermore, a handle 212 is provided on the inner ring 210 .

[0026] The inner ring 210 can be conveniently rotated by the handle 212 to adjust the position of the baffle 211. When the baffle 211 blocks the nozzle 14, the nozzle 14 is no longer in contact with the external environment, thereby preventing dust from falling into the nozzle 14 and clogging the nozzle 14. When the baffle 211 is located between the gaps of the nozzle 14, the nozzle 14 can perform spray dust removal.

[0027] Furthermore, a buckle 222 is provided on the front end surface of the outer ring 220 , and a slot 223 is provided on the side surface of the buckle 222 . The handle 212 is inserted into the slot 223 and is engaged with the buckle 222 .

[0028] The handle 212 is fixed by the buckle 222, so as to prevent the handle 212 from swinging during the spraying process of the mist emitter, causing the baffle 211 to block the nozzle 14, thereby affecting the dust reduction effect.

[0029] Furthermore, the number of the buckles 222 is two, and the center distance between the slots 223 on the two groups of buckles 222 is equal to half of the distance between adjacent nozzles 14.

[0030] The handle 212 is thus divided into two gears, so as to facilitate the control of the position of the baffle 211 and prevent the baffle 211 from shifting and affecting the dust prevention or dust reduction effect.

[0031] Furthermore, a pressure relief plug 230 is provided at the center of the baffle 211 . The pressure relief plug 230 is a cylindrical rubber plug. A pressure relief hole 231 is provided at the center of the pressure relief plug 230 . The pressure relief hole 231 is a conical through hole 213 .

[0032] When the baffle 211 is forgotten to be turned before starting the equipment, the water from the nozzle 14 can pass through the pressure relief hole 231 and flow out slowly, providing the operator with a certain amount of operating time to shut down the equipment, thereby avoiding excessive pressure on the water supply equipment and damage caused by burning, and effectively prolonging the service life of the equipment.

[0033] Furthermore, an annular flange 232 is provided on the side of the pressure relief plug 230 , a through hole 213 is provided at the center of the baffle 211 , and the pressure relief plug 230 is inserted into the through hole 213 and is interference-connected with the baffle 211 .

[0034] The interference fit connection structure allows the pressure relief plug 230 to be pushed open when the spray pressure of the nozzle 14 is too high, thereby increasing the pressure relief diameter and improving the pressure relief effect.

[0035] Furthermore, a dustproof plate 221 is provided on the top of the front end surface of the outer ring 220 .

[0036] The dustproof plate 221 is used to shield the fog cannon barrel 102, thereby further improving the dustproof effect.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
