Description

Technical Field

[0001] The utility model relates to a dust removal structure, in particular to a dust removal structure for a concrete spraying machine. Background Art

[0002] The existing shotcrete feeder conveys the mixed shotcrete to the hopper of the shotcrete machine. The shotcrete machine conveys the concrete to the working surface through air pressure. Due to its own structural reasons, the concrete loaded by the shotcrete machine is usually dry material, which leads to some deficiencies in the work, as follows:

[0003] 1. It causes environmental pollution and large dust, which affects the construction work. During the operation of the shotcrete machine, dust is ejected through the gap between the rotor body of the hopper seat, forming dust. As the dust problem becomes prominent, the construction progress has to be stopped for rectification, which seriously affects the construction progress.

[0004] 2. The dust generated during work can cause certain harm to the health of on-site construction workers. One or two construction workers are required to monitor the spraying machine when it is working to prevent pipe blockage. In this way, the dust generated during work will be inhaled by the construction workers, affecting their health.

[0005] 3. Dust reduces the service life of the motor. The dust generated during the operation of the spraying machine can be easily sucked into the surface of the motor, the surface of the junction box and other locations. The dust at the location of the electrical source components can easily cause short circuits in electrical components, causing the equipment to burn out and become unusable, greatly reducing the service life of electrical components.

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1-3 As shown together, this embodiment is about the dust removal structure of the concrete spraying machine, including the concrete spraying machine 10. It should be noted that the concrete spraying machine 10 is a prior art, including a frame, a walking wheel installed at the lower part of the frame, a concrete spraying machine body, and a motor. Among them, the concrete spraying machine body includes a reducer and a rotor body connected to the output shaft of the reducer. In order to effectively prevent dust, as shown in FIG. Figure 1-2 As shown together, the motor is covered with a housing.

[0033] In this embodiment, the outer ring of the rotor body of the concrete shotcrete machine 10 is wrapped with a dust collecting shield 11, and one side of the motor of the concrete shotcrete machine 10 is equipped with a dust removing mechanism 30, and the concrete shotcrete machine 10 and the dust removing mechanism 30 are connected through a dust collecting part 20; the dust collecting part 20 includes an exhaust pipe 21 connected to the dust removing mechanism 30; the dust removing mechanism 30 includes a dust removing box 31 with an inner cavity space, and an air inlet 32 ​​connected to the exhaust pipe 21 is provided on the dust removing box 31. The inner cavity space of the dust removing box 31 is divided into a clean air chamber 34 and a dust and dirt chamber 35 by a dust removing bag 33, and a dust removing motor 38 is arranged on the top of the dust removing box 31, and the dust removing motor 38 is driven by a centrifugal fan 39 arranged in the dust removing box 31.

[0034] Preferably, a visual observation port is provided on the dust collecting shield 11, and the observation port can be in the form of a perspective mirror or flat glass, for observing whether the slurry blocks the gap between the dust collecting shield 11 and the rotor body. In order to further facilitate the operation, in the actual production process, a paddle component (not shown in the figure) is provided at the lower part of the rotor body. When there is accumulated slurry in the gap between the dust collecting shield 11 and the rotor body, the accumulated spraying material is pushed out by the paddle component.

[0035] The exhaust pipe 21 extending toward one side of the concrete spraying machine 10 is divided into a first branch pipe 22 and a second branch pipe 23, and the second branch pipe 23 is also connected to a third branch pipe 24; the confluence of the exhaust pipe 21 is connected to the exhaust pipe 21 through a hose, and the confluence here is as follows Figure 2 Shown is the junction of the first branch pipe 22 and the second branch pipe 23. It should be noted that the installation positions of the respective interfaces of the first branch pipe 22, the second branch pipe 23 and the third branch pipe 24 of this embodiment are also equipped with sealing gaskets to enhance sealing. It can be understood that the dust collecting part 20 provides channel support for the dust removal mechanism 30 to absorb dust from the concrete spraying machine 10.

[0036] Preferably, the first branch pipe 22 is arranged at the hopper seat position of the concrete spraying machine 10 and is connected to the interior thereof. In the present embodiment, the two are connected by threads; the second branch pipe 23 is connected to the interior thereof through the residual material port opened on the dust collecting shield 11; the third branch pipe 24 is arranged at the junction of the reducer and the panel of the concrete spraying machine 10 and is connected to the interior of the corresponding position.

[0037] The dust removal box 31 is arranged vertically, and the dust removal bag 33 is arranged above the waist in the inner cavity space of the dust removal box 31. The dust removal bag 33 is provided with a vibration motor 37 located in the clean air chamber 34, and the vibration motor 37 is used to quickly shake off the dust attached to the dust removal bag 33.

[0038] The clean air chamber 34 is located directly above the dust and dirt chamber 35, and the dust and dirt chamber 35 is connected to the air inlet 32. Directly below the dust and dirt chamber 35 is a connected dust drawer 36. Therefore, it can be understood that the dust accelerated by the vibration motor 37 falls into the dust drawer 36 under the action of gravity, which is convenient for the operator to handle it in a centralized and regular manner.

[0039] The space where the centrifugal fan 39 is located forms a fan chamber 42, and the fan chamber 42 is connected to the clean air chamber 34 by the dual cooperation of the hinge 40 and the buckle 41, as shown in 3. It should be noted that the above technical features are specifically as follows in the actual production process: the upper cover part of the dust removal box 31 provided with the dust removal motor 38 is connected to the other parts of the dust removal box 31 through the hinge 40, and is locked / unlocked by the buckle 41, then the upper part of the part separated by the horizontal extension line of the hinge 40 is the fan chamber 42, and the lower part is the clean air chamber 34.

[0040] One side of the fan chamber 42 is connected to an air outlet box 43 which is independent of the dust removal box 31. The opening at the connection between the fan chamber 42 and the air box 43 corresponds to the height of the centrifugal fan 39. In addition, the centrifugal fan 39 is preferably a turbine centrifugal fan.

[0041] In this embodiment, the dust removal motor 38 is started to drive the centrifugal fan 39 to operate. Under the suction of the centrifugal fan 39, the dust inside the concrete spraying machine 10 is sucked into the dust chamber 35 of the dust removal box 31 through the first branch pipe 22, the second branch pipe 23, and the third branch pipe 24 at the same time. Under the suction, the dust bag 33 blocks the dust, and the purified air is transmitted upward and finally discharged through the bellows 43. The blocked dust is quickly shaken off into the dust drawer 36 under the dual action of the centrifugal fan 39 and gravity.

[0042] Thus, the dust removal structure of the concrete spraying machine disclosed in the utility model is conducive to the development of environmental protection work, which not only ensures the normal construction of the project, but also ensures that the environment is not polluted by dust, and specifically has the following advantages:

[0043] 1. Solve dust and reduce environmental pollution. During the working process, the dust is fully recovered into the dust removal box at the air outlet, and the dust is fully reduced after filtration;

[0044] 2. Construction workers do not need to be bothered by dust during work. After dust removal by dust removal equipment, dust materials are finally stored in the dust collection drawer in a static form and will no longer be inhaled in the air.

[0045] 3. After the dust problem is solved, it will no longer affect the use of electrical equipment, which indirectly increases the service life of the equipment.

[0046] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
