Description

Изобретение относитс  к устройствам дл  автоматического регулировани  работы шаровой мельницы мокрого помола, работающим путем определени  частоты издаваемого мельницей шума, дл  улавливани  которого у обечайки мельницы установлен микрофон.The invention relates to devices for automatically controlling the operation of a wet grinding ball mill, operating by determining the frequency of noise emitted by a mill, for which a microphone is installed at the side of the mill side.

Известные подобные устройства не обеспечивают необходимой степени четкости в работе, так как на их микрофоны вли ют посторонние шумы, накладывающиес  на шумы мельницы и тем самым искажающие шумовую характеристику.The known similar devices do not provide the necessary degree of clarity in operation, since their microphones are influenced by extraneous noise superimposed on the noise of the mill and thereby distort the noise characteristic.

В описываемом устройстве этот недостаток устранен тем, что микрофон укреплен па плате, оклеенной со стороны обечайки мельницы звукопоглощающим материалом, например войлоком, а в плате сделано отверстие дл  передачи шумов мельницы к микрофону.In the described device, this disadvantage is eliminated by the fact that the microphone is reinforced on the board, pasted over from the side of the mill shell with sound-absorbing material, such as felt, and the board has an opening for transmitting the mill noise to the microphone.

На чертеже показана схема установки устройства у мельницы.The drawing shows the setup diagram of the device at the mill.

У барабана / мельницы мокрого помола установлена на фундаменте плоска  колонна 2, котора  может быть изоготовлена, например, из швеллерного железа. Колонна 2 предназначена дл  установки на ней, на упругом (типа рессоры) рычаге 3 платы 4 с укрепленным на ней микрофоном 5.At the wet grinding drum / mill, a flat column 2 is installed on the foundation, which can be iso-prepared, for example, from channel iron. Column 2 is designed to be mounted on it, on an elastic (like a spring) lever 3 of board 4 with microphone 5 fixed on it.

На колонне 2 сделаны прорези 6 дл  пропуска болтов 7, креп щих опорный сектор 8 рычага 3. Сектор 8 имеет прорезь 9. Такое крепление (рычаг 3, сектор 8, болты 7, прорези 5 и 9) позвол ет регулировать положение платы 4 и микрофона 5 относительно барабана / мельницы.Slot 6 is made on column 2 to pass the bolts 7 securing the support sector 8 of the lever 3. Sector 8 has a slot 9. This mounting (lever 3, sector 8, bolts 7, slots 5 and 9) allows you to adjust the position of the board 4 and the microphone 5 relative to the drum / mill.

С целью устранени  вли ни  посторонних шумов на микрофон, плата 4 оклеена со стороны обечайки мельницы звукопоглощающим материалом 10, например войлоком, кра  которого дополнительно прикреплены к плате при помощи болтов 11.In order to eliminate the effect of extraneous noise on the microphone, the board 4 is glued on from the side of the mill side of the mill with sound-absorbing material 10, for example, felt, the edges of which are additionally attached to the board using bolts 11.

Дл  передачи же шумов мельницы к микрофону 5, в плате 4 (и в звукопоглощающем материале) сделано отверстие 12.To transmit the noise of the mill to the microphone 5, a hole 12 is made in the board 4 (and in the sound-absorbing material).
