Description

Technical Field

[0001] This utility model relates to the technical field of construction site dust removal equipment, and in particular to a construction dust removal device that is easy to clean. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities.

[0003] Construction generates a lot of dust, so dust removal equipment is needed. The most commonly used dust removal equipment during construction is spray dust removal equipment, which can effectively settle the dust raised during construction by spraying water mist, preventing dust from spreading everywhere.

[0004] Chinese utility model patent application CN202323308918.6 describes a construction dust removal device that is easy to clean. It features a push rod, a lower through slot, and an upper through slot. The push rod passes through the upper through slot and inserts into the lower through slot. The push rod simply pushes an insert block inward, causing the insert block to slide within the slot. The movement of the slide block deforms a spring until the insert block extends into the slot. The fixing base and filter body can then be easily removed from the mounting base, facilitating replacement and cleaning of the filter body. However, disassembling the filter body requires pushing the push rod, and the device contains multiple push rods. Multiple push rods must be used simultaneously to successfully remove the filter body, making it difficult for a single person to complete the disassembly independently and increasing the difficulty of cleaning the dust removal device. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please refer to Figures 1-7 The construction dust removal device shown includes a mounting box 1, a turntable 2 rotatably connected to the top of the mounting box 1, a mounting frame 3 fixedly connected to the top of the turntable 2, a duct 4 rotatably connected to the mounting frame 3 via a first rotating shaft, a first hydraulic cylinder 5 hinged between the bottom of the duct 4 and the mounting frame 3, and a filter assembly 6 connected to the left end of the duct 4.

The outer diameters of the two annular water pipes 41 are different and their axis lines coincide. A water inlet pipe 43 is connected to the side of one of the annular water pipes 41.

[0048] Working principle: When disassembling the filter screen 63, rotate the first threaded rod 642 until it is pulled out of the third insertion hole 644. Then, turn the knob 626 clockwise. At this time, the knob 626 pulls the pull rope 6253. The pull rope 6253 overcomes the elastic force of the first elastic element 6252 and pulls the insertion rod 623 out of the second insertion hole 624. At this time, the fixing ring 621 and the elastic ring 71 can be taken out from the fixing cylinder 61. Then, the filter screen 63 and the sealing ring 81 can be taken out from the fixing cylinder 61. The disassembly operation of the filter screen 63 can be completed conveniently, thus simplifying the cleaning work of the dust removal device.
