Description
Technical field
The present invention relates to the vertically arranged protective case of a kind of belt feeder hopper blocking rotary type level-sensing device.
Background technology
Belt feeder is a kind of continuous action formula load transfer device extensively adopted in the fields such as the harbour of coal preparation plant, washery and defeated coal, defeated Jiao.By hopper, two belts are linked together in belt feeder intersection, realize continuous seepage.In order to realize, transport material is not outer to be spilt, and usually hopper is made trumpet type.Thus comparatively strong or that bulk the is larger transport material of some viscosity is blocked at the feed opening of hopper sometimes, cause feed bin spill-over, equipment is caused damage.Blocking rotary type level-sensing device can be measured the height of material level in feed bin and give warning in advance.For granular material, level-sensing device can be directly installed in feed bin, for lump material, needs to install protection net additional, to protect the safety of level-sensing device.For the larger-size belt feeder of hopper, level-sensing device level can be arranged on hopper side, for hopper size, less or transport material is full of the belt feeder of hopper, due to transport material rub for a long time, wash away and bulk supplied materials pound, level-sensing device is caused damage, lateral vertical now should be adopted to install.
According to size and the external form of blocking rotary type level-sensing device, the rotary wings of level-sensing device needs to expect directly to contact to determine feed bin whether putty with transporting.For hopper size, less or transport material can be full of the hopper inwall of hopper; generally liner plate is all installed to be worn to prevent bucket wall; therefore the level-sensing device for this kind of situation can only be arranged on the outer wall of hopper; it is different from traditional level-sensing device and is installed in hopper; the protective case of level-sensing device had both needed to provide failure-free to protect to level-sensing device; need again to guarantee that the rotary wings of level-sensing device expects reliable contacts with transport, therefore traditional defense guard is not suitable with the level-sensing device of hopper outer wall.
Summary of the invention
Technical matters to be solved by this invention is to provide the vertically arranged protective case of a kind of belt feeder hopper blocking rotary type level-sensing device; this protective case structure is simple; failure-free is provided to protect to the level-sensing device being installed on hopper outer wall; and guarantee that the rotary wings of level-sensing device and interior transport of hopper expect reliable contacts; thus Measurement accuracy is made and early warning to material level in hopper, ensure that the normal operation of belt feeder.
For solving the problems of the technologies described above, the vertically arranged protective case of belt feeder hopper blocking rotary type level-sensing device of the present invention comprises hopper body, flange, protective housing and pipe, described protective housing one side opening, opposite side hypomere is dip plane in opposite directions, described protective housing end face is provided with circular hole, described pipe hypomere is provided with opening vertically, described pipe penetrates the circular hole of described protective housing end face and opening hypomere is positioned at described protective housing, described pipe and described protective housing end face are welded to connect, the opening surface of described pipe hypomere is to the dip plane of described protective housing, described flange is located at the end face of described pipe, described hopper body sidewall is provided with through hole, the open side of described protective housing is welded in described hopper body sidewall and covers the through hole of hopper base side wall.
Because the vertically arranged protective case of belt feeder hopper blocking rotary type level-sensing device of the present invention have employed technique scheme, i.e. protective housing one side opening of this protective case, opposite side hypomere is dip plane in opposite directions, protective housing end face is provided with circular hole, pipe hypomere is provided with opening vertically, pipe penetrates the circular hole of protective housing end face and opening hypomere is positioned at protective housing, pipe and protective housing end face are welded to connect, the opening surface of pipe hypomere is to the dip plane of protective housing, flange is located at the end face of pipe, hopper body sidewall is provided with through hole, the open side of protective housing is welded in hopper body sidewall and covers the through hole of hopper base side wall.This protective case structure is simple, provides failure-free to protect to the level-sensing device being installed on hopper outer wall, and guarantees that the rotary wings of level-sensing device and interior transport of hopper expect reliable contacts, thus makes Measurement accuracy and early warning to material level in hopper, ensure that the normal operation of belt feeder.
