Description

Technical Field

[0001] The utility model relates to the technical field of dust collection, in particular to a cement mill dust precision detection and directional dust collection device. Background Art

[0002] Cement mill is the key equipment for crushing materials after they are broken. Ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics and other production industries to grind various ores and other grindable materials by dry or wet method.

[0003] Dust will be generated during the operation of cement mill. The dust not only affects the working environment, but also affects the health of the workers. At present, dust collecting devices are installed at the dust generating part of cement mill. The dust collecting devices do not have dust detection function. When dust appears, the device needs to be manually turned on to collect dust. When there is no dust, the device will continue to work, resulting in unnecessary energy consumption. Utility Model Content

[0004] The purpose of the utility model is to provide a cement mill dust accurate detection and directional dust collection device, which has the advantages of being able to clean the filter structure, and having a dust detection function, and can automatically perform dust collection work, thereby solving the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cement mill dust accurate detection and directional dust collection device, comprising a dust collecting box and a first dust suction pipe, a control panel is provided at the side end of the dust collecting box, a bellows is installed at the upper end of the dust collecting box, a connecting port is provided between the bellows and the dust collecting box, a dust filter is provided in the connecting port, a symmetrically distributed first mounting rod is installed on the inner wall of the dust collecting box, a first driving device is installed at the end of the first mounting rod, a brush plate is installed at the end of the main shaft of the first driving device, the brush plate is in contact with the dust filter, a symmetrically distributed second mounting rod is installed in the bellows, a second driving device is installed between the second mounting rods, a fan blade is installed at the end of the main shaft of the second driving device, two of the first dust suction pipes are symmetrically installed at the rear end of the dust collecting box, the first dust suction pipe is connected to the dust collecting box, a second dust suction pipe is installed at the end of the first dust suction pipe, a trumpet dust suction port distributed in an array is provided at the lower end of the second dust suction pipe, a symmetrically distributed fixing rod is installed on the outer surface of the inner ring of the second dust suction pipe, and a dust detector is installed at the end of the fixing rod.

[0006] When using the cement mill dust accurate detection and directional dust collection device of the utility model,

[0007] The utility model is arranged at the cement mill discharge point so that the cement mill discharge pipe is located between the dust detectors on the inner circle of the second dust suction pipe. The dust detector can detect whether there is dust in the air. When dust is detected, the built-in controller in the control panel will control the operation of the equipment in the utility model. The fan blades can be made to rotate at high speed through the operation of the second driving device. The high-speed rotation of the fan blades can generate negative pressure in the bellows and the dust collecting box. The dust can be absorbed by the first dust suction pipe and the second dust suction pipe in cooperation with the horn dust suction port. The absorbed dust will enter the dust collecting box. The air can be discharged from the connecting port. The dust can be intercepted by the dust filter. When it is detected that there is no dust, the utility model stops working. When the utility model is at work, the brush plate can be made to rotate through the operation of the first driving device. The dust filter can be cleaned by the rotation of the brush plate, so as to prevent the dust from clogging the dust filter.

[0008] Preferably, a support leg is installed at the lower end of the dust collecting box, and there are four support legs in total, and the four support legs are distributed in an array with respect to the dust collecting box.

[0009] Preferably, a dust exhaust pipe connected to the dust collecting box is installed at the lower end of the dust collecting box, and a valve is provided on the dust exhaust pipe.

[0010] Preferably, an air outlet is provided at the upper end of the bellows, and a total of four air outlets are provided and distributed in an array about the bellows.

[0011] Preferably, the front end of the dust collecting box is provided with symmetrically distributed box doors, and the front end of the box door is provided with a handle.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The dust detector can be used to detect whether there is dust in the air. When dust is detected, the built-in controller in the control panel will control the equipment in the utility model to work, thereby collecting dust. When it is detected that there is no dust, the utility model stops working. It has a dust detection function and can automatically collect dust to prevent unnecessary energy consumption.

[0014] 2. During the dust collection work, the first driving device can be used to rotate the brush plate, and the dust filter can be cleaned by the rotation of the brush plate. The dust attached to the lower end of the dust filter can be cleaned and swept down, which can prevent the dust from clogging the dust filter, so that the utility model can stably perform the dust collection work.
