Description

Technical Field

[0001] The utility model relates to the technical field of spray dust removal, in particular to a spray dust removal device. Background Art

[0002] The composition of construction waste is complex, including a large amount of soil, gravel and cement blocks. The waste needs to be screened. After screening, the cement blocks need to be crushed before entering the subsequent process. The broken cement blocks usually carry a lot of dust. These cement blocks need to be treated with dust reduction and dust removal during transportation and subsequent processing. Usually, the cement blocks are treated by spraying, which not only causes a waste of water resources, but also produces a large amount of muddy water, which affects the normal operation of the equipment after long-term use.

[0003] Therefore, in view of the above problems, a spray dust removal device is proposed to solve the above problems. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, the utility model develops a spray dust removal device, which can remove dust from broken cement block materials and automatically scrape off the generated muddy water to ensure the normal operation of the equipment.

[0005] The technical solution to the technical problem solved by the utility model is: a spray dust removal device, including a bracket, a dust removal bin is mounted on the bracket, a mounting frame is arranged in the dust removal bin, a conveyor belt is arranged on the mounting frame, a spray part is arranged in the dust removal bin, a collecting chamber is arranged below the dust removal bin, and a scraping part is arranged in the collecting chamber.

[0006] The material enters the conveyor belt of the dust removal bin and moves along the conveyor belt in the dust removal bin. The spray part sprays water mist on the material, so that the dust carried by the material absorbs water to increase its weight and reduce the dispersion of dust. Part of the dust absorbs too much water and becomes mud and flows into the collection chamber. The scraping part scrapes and collects the mud in the collection chamber for the next step of processing.

[0007] Preferably, the spray part includes a water pipe, a spray pipe, an atomizing nozzle and a tee pipe. Multiple spray pipes are horizontally installed in the dust removal bin. The spray pipes are located above the conveyor belt. Multiple atomizing nozzles are radially arranged on the spray pipes. The spray pipes are connected to the water pipe through a tee pipe. The water pipe is installed outside the dust removal bin.

[0008] The water pipe transports the water required for spray dust removal to the spray pipe through the three-way pipe. The spray pipe sprays the water through the atomizing nozzle. The sprayed water mist forms a water curtain and covers the conveyor belt downward. Multiple spray pipes form a multi-layer water curtain. The material on the conveyor belt continuously passes through the water curtain, which improves the dust removal effect and reduces the waste of water resources.

[0009] Preferably, the scraping part includes a scraper, a first connecting rod, a second connecting rod and a slide groove. The scraper is arranged in the collecting chamber, and the shape of the scraper is the same as the cross-sectional shape of the collecting chamber. The side walls on both sides of the collecting chamber are horizontally arranged with slide grooves. The first connecting rod and the second connecting rod are respectively connected in the slide grooves on both sides of the collecting chamber, and the first connecting rod and the second connecting rod are connected to the driving structure.

[0010] The scraper moves in the collection chamber through the driving structure. During the movement, the scraper scrapes off the mud and water attached to the inner wall of the collection chamber to prevent the accumulation of mud and water.

[0011] Preferably, the scraping part also includes a guide plate, a drainage hole and a maintenance door. The drainage holes are symmetrically arranged at the lower part of the collecting chamber, and the guide plates are symmetrically arranged on the inner wall of the collecting chamber. The guide plates are located above the slide groove, the guide plates are inclined downward, and a maintenance door is arranged at one end of the collecting chamber.

[0012] The scraper pushes the muddy water to the drain hole for discharge during the movement. The guide plate arranged above the chute guides the muddy water to prevent the muddy water on the inner wall of the collecting chamber from flowing out of the chute during the downward flow. When there is too much muddy water in the collecting chamber and blockage occurs, open the maintenance door for further cleaning and maintenance to ensure the normal operation of the equipment.

[0013] Preferably, the driving structure includes a slide rail, a motor, a gear, a rack and a first mounting plate. The first mounting plate is horizontally arranged on the outside of the collecting chamber. The first mounting plate is located below the slide groove. The slide rail is arranged on the first mounting plate. The slide rail is slidably connected to the motor. One side of the output end of the motor is connected to the first connecting rod. A gear is arranged at the output end of the motor. The gear and the rack are meshed with each other. The rack is arranged on the first mounting plate.

[0014] The output end of the motor drives the gear to rotate. Through the cooperation of the gear and the rack, the gear drives the motor to move in the horizontal direction. The motor drives the scraper to move through the first connecting rod, so that the scraper can scrape away the mud and water in the collection chamber.

[0015] Preferably, the driving structure also includes a second mounting plate, a roller and a limiting groove. The second mounting plate is horizontally arranged outside the collecting chamber, the limiting groove is arranged on the second mounting plate, the roller is rollingly arranged in the limiting groove, and the roller is rotatably connected to the second connecting rod.

[0016] The roller provides a certain support to the scraper, assisting the scraper in moving.

[0017] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0018] Multiple spray pipes form a multi-layer water curtain, and the materials on the conveyor belt continuously pass through the water curtain, which improves the dust removal effect and reduces the waste of water resources;

[0019] The scraper moves in the collection chamber through the driving structure. During the movement, the scraper scrapes away the mud and water attached to the inner wall of the collection chamber to prevent the accumulation of mud and water.

[0020] The guide plate set above the chute plays a role in guiding the muddy water, preventing the muddy water on the inner wall of the collection chamber from flowing out of the chute during the downward flow. When there is too much muddy water in the collection chamber and blockage occurs, open the maintenance door for further cleaning and maintenance to ensure the normal operation of the equipment.
