[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] See also Figure 1 The present application provides a high-efficiency dust collection device, including a first dust collection hood 1, a second dust collection hood 2, a first belt 3, a second belt 4, a discharge chute 5 and a dust collector 6.
[0022] The first dust hood 1 and the second dust hood 2 are hollow boxes for enclosing dust collection. The first dust hood 1 is fixed above the second dust hood 2. Safety doors are provided on the side walls of the first dust hood 1 and the second dust hood for observing the dust collection situation in the first dust hood 1 or the second dust hood 2 and cleaning the equipment therein.
[0023] The first belt 3 is fixedly arranged in the first dust collecting cover 1, and its input end is connected with the material output port for transporting materials.
[0024] The second belt 4 is fixed in the second dust collecting cover 2, and the second belt 4 and the first belt 3 are arranged to intersect vertically on the horizontal projection plane, and the intersection is the output end of the first belt 3 (the material drop point of the first belt 3), and is also the material receiving point of the second belt 4. During operation, the slag is transported to the output end of the first belt 3 and then falls onto the second belt 4 for further transportation.
[0025] The discharge chute 5 is vertically arranged and passes through the first dust collecting hood 1 and the second dust collecting hood 2. The upper end thereof is correspondingly connected to the output end of the first belt 3, and the lower end thereof is correspondingly connected to the second belt 4. Specifically, it is located above the material receiving point of the second belt 4, and is used to transfer the slag on the first belt 3 to the second belt 4 through the discharge chute 5, which can reduce the dust leakage phenomenon during the transfer process.
[0026] In other embodiments, the material discharge chute 5 is arranged at an angle to prevent the slag from falling with too much force and causing large amounts of smoke and dust.
[0027] The dust collector 6 is fixedly mounted above the first dust hood 1 through a bracket, and a first dust collecting pipe 7 is connected to the inlet of the dust collector 6. One end of the first dust collecting pipe 7 away from the dust collector 6 is communicated with the side wall of the first dust hood 1 and the second dust hood 2, respectively, for collecting the dust-containing airflow in the first dust hood 1 and the second dust hood 2 into the dust collector 6. When working, the dust collector 6 is in a slightly negative pressure state.
[0028] The lower end of the dust collector 6 is connected to a dust collecting hopper 61, and the lower end of the dust collecting hopper 61 is connected to a vertically arranged dust discharge pipe 62, and the end of the dust discharge pipe 62 is connected to the material discharge chute 5. When working, the dust collector 6 collects the dust-containing airflow in the first dust collecting hood 1 and the second dust collecting hood 2 through the first dust collecting pipe 7, filters it, and discharges the airflow. The remaining dust remains in the dust collecting hopper 61, is transferred to the material discharge chute 5 through the dust discharge pipe 62, and is transferred to the second belt 4 together with the slag falling from the output end of the first belt 3 for further transportation.
[0029] Further, the connection between the first dust collecting hood 1 and the first dust collecting pipe 7 is provided with a first dust collecting port 71, and the connection between the second dust collecting hood 2 and the first dust collecting pipe 7 is provided with a second dust collecting port 72. The first dust collecting port 71 and the second dust collecting port 72 have the same structure, and the cross section of the end close to the first dust collecting pipe 7 is circular, and the cross section of the end close to the first dust collecting hood 1 or the second dust collecting hood 2 is rectangular, and the rectangular area is larger than the circular area. Such a structural design can not only increase the dust collection effect, but also prevent dust accumulation.
[0030] It also includes a head dust collecting hood 8, which is fixed above the output end of the first belt 3, and the upper end of which is connected to a second dust collecting pipe 81, which is vertically arranged and connected to the first dust collecting pipe 7, and is connected to the inlet of the dust collector 6 through the first dust collecting pipe 7. Since the output end of the first belt 3 needs to drop material to the material discharge chute 5, there is serious dust overflow. When working, the head dust collecting hood 8 can accurately collect the dust here to improve the dust collection effect.
[0031] Furthermore, there is a distance between the material connection point of the second belt 4 and the input end of the second belt 4, which is convenient for later maintenance and replacement of the belt.
[0032] During operation, the first belt 3 transports materials and transfers them to the second belt 4 through the unloading chute 5 for further transportation. The head dust hood 8 collects dust accurately at the output end of the first belt 3, and the dusty airflow there is collected to the dust collector 6 through the second dust collecting pipe 81; the remaining dusty airflow not collected in the first dust hood 1 and the second dust hood 2 is collected to the dust collector 6 through the first dust collecting pipe 7. The dust collector 6 filters the collected dusty airflow, discharges the airflow, and the dust falls into the dust hopper 61, and is transferred to the unloading chute 5 through the dust discharge pipe 62, and is transferred to the second belt 4 together with the slag falling from the output end of the first belt 3 for further transportation. This dust collection process is a circular dust collection process.
[0033] The high-efficiency dust collecting device forms a closed space by setting a first dust collecting hood 1 and a second dust collecting hood 2, and placing a first belt 3 and a second belt 4 therein, isolating the external environment, and forming a slightly negative pressure state in the first dust collecting hood 1 and the second dust collecting hood 2, which not only has a good dust collecting effect, but also reduces pollution to the surroundings, and is clean and environmentally friendly.
[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
