Technical Field
[0001] This utility model relates to the technical field of protection for mixing plants, and in particular to an integrated dust removal and noise reduction device for commercial concrete mixing plants. Background Technology
[0002] A concrete mixing plant is an industrial facility used for the centralized production of commercial concrete or concrete for engineering projects. It prepares concrete that meets the requirements of the project by mixing raw materials such as cement, aggregates, water, and admixtures in a specific ratio. It is an indispensable core equipment in modern construction and is widely used in construction, road, bridge, water conservancy and other engineering fields. Because it needs to mix sand and gravel, it generates a lot of noise during operation, which affects the surrounding living environment.
[0003] The prior art Chinese utility model patent with application number CN202320928410.7 relates to a noise reduction device for a concrete mixing plant, which includes a main body, a mixing drum, a motor, a mixing shaft, a mixing rod, a feeding hopper, a solenoid valve, a connecting frame, and a feeding pipe, etc., which can reduce vibration of the device, thereby reducing the noise generated by vibration during mixing.
[0004] However, the aforementioned devices are difficult to modify for existing mixing plants, and the installation, dismantling, and transportation of existing fence-type noise reduction equipment consumes a lot of manpower. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides an integrated dust removal and noise reduction device for commercial concrete mixing plants. This device uses a noise reduction mechanism to enclose the main operating area of the mixing plant, intercepting noise during its propagation and reducing its impact on the surrounding environment. It is also easy to assemble and disassemble. An auxiliary device provides support during the installation of the noise reduction device, and a guiding device guides the operation of the auxiliary device, reducing wear between the auxiliary device and the noise reduction device and improving the practicality of the device.
[0006] This utility model discloses an integrated dust removal and noise reduction device for commercial concrete mixing plants. It includes a noise reduction device, an auxiliary device, and a guiding device. The auxiliary device and the guiding device are installed on the noise reduction device. The noise reduction device encloses the main operating area of the mixing plant, intercepting noise during its propagation and reducing its impact on the surrounding environment. It also facilitates assembly and disassembly. The auxiliary device provides support during the installation of the noise reduction device, and the guiding device guides the auxiliary device during operation, reducing wear between the auxiliary device and the noise reduction device and improving the device's practicality.
[0007] Preferably, the noise reduction device includes a base plate, internally threaded mounting seats, support pipes, an arc-shaped airbag, and a U-shaped structure. The base plate has a set of internally threaded mounting seats on each of its upper left and right sides. The base plate is fixed to the ground with anchor bolts. The bottoms of the two sets of support pipes are connected to the two sets of internally threaded mounting seats respectively. The arc-shaped airbag is located on the upper side of the base plate, and a set of U-shaped structures is provided on each side of the arc-shaped airbag. The base plate supports the main body of the equipment. By inflating the arc-shaped airbag, it expands, causing the two sets of support pipes to be engaged in the U-shaped structures on both sides of the arc-shaped airbag, thus limiting the position of the main body of the arc-shaped airbag. By splicing multiple noise reduction devices adjacent to each other, the mixing plant area is enclosed, reducing the impact of noise on the surrounding environment. Furthermore, the equipment itself is easy to disassemble, and the arc-shaped airbag can be quickly deflated in windy weather to ensure equipment safety, improving the practicality of the device.
[0008] Preferably, the device also includes a horizontal pipe and a vertical pipe. A horizontal pipe is provided on the upper part of the inner side of the arc-shaped airbag, and multiple sets of atomizing nozzles are installed on the horizontal pipe. A vertical pipe is connected to the middle of the horizontal pipe, and the vertical pipe extends from the surface of the arc-shaped airbag to the lower part of the arc-shaped airbag. Pressurized water is delivered to the multiple sets of atomizing nozzles on the horizontal pipe through a water source pipe connected to the vertical pipe, thereby assisting in dust suppression in the internal area of the mixing plant and improving the practicality of the device.
[0009] Preferably, the auxiliary device includes a reinforcing belt, connecting rods, steel wire ropes, and handles. A reinforcing belt is provided on the upper surface of the arc-shaped airbag, and multiple sets of connecting rods are evenly distributed on the upper surface of the reinforcing belt. The upper part of the connecting rods is provided with circular holes, and the steel wire rope passes through the circular holes on the upper part of the multiple sets of connecting rods. A set of handles is provided at each end of the steel wire rope. During the inflation of the arc-shaped airbag, the main body of the arc-shaped airbag is pulled up by the cooperation of the steel wire rope and the multiple sets of steel wire rope holes, which prevents the arc-shaped airbag from partially folding and affecting its inflation efficiency or causing the U-shaped structure to detach from the support tube. The handles make it easy for the operator to pull up the steel wire rope, and the reinforcing belt increases the strength of the top of the arc-shaped airbag, improving the practicality of the device.
[0010] Preferably, the guiding device includes a mounting base, a rotating base, a support frame, a first guide wheel, and a second guide wheel. The top of the inner side of the support tube is provided with an internal thread. The lower part of the mounting base is connected to the top of the support tube. The lower part of the rotating base is connected to the upper part of the mounting base via a bearing. The first guide wheel is mounted on the upper end face of the rotating base via the support frame. A rectangular hole is provided on the lower side of the support tube, and the second guide wheel is installed in the rectangular hole. The first and second guide wheels guide the wire rope, allowing it to pass through the support tube and extend to the lower part of the support tube, facilitating the operator to pull up the wire rope. The bearing between the mounting base and the rotating base allows the main body of the support frame to rotate, facilitating the directional changes caused by the wire rope's own swaying during the pulling process, thus improving the practicality of the device.
[0011] Preferably, it also includes a variable diameter hole. The rotating seat is provided with a variable diameter hole. The top of the variable diameter hole is rectangular and the bottom end face of the variable diameter hole is circular. The variable diameter hole provided on the rotating seat increases the installation area left for the support frame on the upper end face of the rotating seat, increases the structural strength of the support frame, and the circular design of the bottom end face of the variable diameter hole reduces the friction and scratches between the wire rope and the rotating seat, thus improving the practicality of the device.
[0012] Preferably, it also includes chamfers and wire rope threading holes. A chamfer is provided on the upper part of the inner side of the rectangular hole at the bottom of the support pipe, and a set of wire rope threading holes is provided on each of the two sets of outer surfaces of the support frame. The chamfer reduces frictional damage between the wire rope and the support pipe, and the wire rope threading holes facilitate the pulling of the external wire rope to the ground to assist in fixing the main body of the equipment, reducing the impact of gusts on the equipment and increasing the stability and practicality of the equipment.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by using a noise reduction device to enclose the main working area of the mixing plant, the noise is intercepted during its propagation, reducing the impact of noise propagation on the surrounding environment, and facilitating assembly and disassembly. The auxiliary device provides auxiliary support for the installation process of the noise reduction device, and the guiding device guides the operation process of the auxiliary device, reducing wear between the auxiliary device and the noise reduction device, and improving the practicality of the device.
