Abstract
The utility model discloses a vacuum filtration machine, including suction filtration groove and filter bag, be equipped with the support orifice plate in the suction filtration groove, the filter bag bottom is spread and is put on supporting the orifice plate, sack from the trough rim evagination in suction filtration groove, suction filtration tank bottom portion is equipped with intercommunication evacuating device's fluid -discharge tube, still install on the suction filtration groove and detect the pressure measurement who supports the suction filtration groove intra cavitary pressure below the orifice plate, master control set is connected to pressure measurement's output, the master control set output is connected with the alarm, predetermine alarm threshold value among the master control set, when pressure measurement's output valve surpasss alarm threshold value, the master control set activate the alarm ware. The utility model discloses a pressure measurement real -time detection supports the vacuum of orifice plate below to judge that the filter bag mesh blocks up the condition, in time send the warning when the jam is serious, the filter effect can effectively be ensured in the suggestion clearance, and filter bag and evacuating device's life.
Description
Technical field
This utility model relates to a kind of vacuum filtration machine.
Background technology
Vacuum filtration machine is the filter plant realizing solid-liquid separation with negative pressure of vacuum for motive force, including suction filtration tank and filter bag, described suction filtration tank is provided with support orifice plate, it is laid in bottom described filter bag on support orifice plate, bag mouth is routed up from the trough rim of suction filtration tank, the discharging tube of vacuum extractor it is communicated with bottom described suction filtration tank, mixed material is sent in filter bag, the negative pressure of vacuum extraction liquid produced by vacuum extractor, along with solid builds up, the mesh of filter bag is the most blocked, support the vacuum below orifice plate more and more higher, prior art cannot know filter bag mesh chocking-up degree, filter bag can be stretched, mesh gradually expands, affect filter effect and service life, and too high negative pressure of vacuum value will also result in adverse effect to the service life of vacuum extractor.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of vacuum filtration machine, can solve existing vacuum filtration machine and cannot know filter bag mesh chocking-up degree, causes affecting filter effect, and filter bag and the problem in vacuum extractor service life.
This utility model is achieved through the following technical solutions:
A kind of vacuum filtration machine, including suction filtration tank and filter bag, described suction filtration tank is provided with support orifice plate, it is laid in bottom described filter bag on support orifice plate, bag mouth is routed up from the trough rim of suction filtration tank, the discharging tube of vacuum extractor it is communicated with bottom described suction filtration tank, it is also equipped with detection on described suction filtration tank and supports the pressure-detecting device of the suction filtration tank chamber pressure below orifice plate, the outfan of described pressure-detecting device connects master control set, described master control set outfan connects alarm, preset alarm threshold value in described master control set, when the output valve of pressure-detecting device is beyond alarm threshold value, master control set starts alarm.
Further scheme of the present utility model is, described suction filtration tank outer wall is provided with connection and supports the communicating pipe of the suction filtration tank inner chamber below orifice plate, upwardly extends described communicating pipe, and described pressure-detecting device is arranged on the upper port of communicating pipe.
Further scheme of the present utility model is that described master control set outfan is also connected with the controller of vacuum extractor, and when the output valve of pressure-detecting device is beyond alarm threshold value, master control set closes vacuum extractor.
Further scheme of the present utility model is, described pressure-detecting device is vacuum transducer.
Further scheme of the present utility model is, described master control set is single-chip microcomputer or PLC.
This utility model advantage compared with prior art is:
One, detected the vacuum supported below orifice plate by pressure-detecting device in real time, to judge filter bag mesh stopping state, send warning, prompting cleaning in time when blocking serious, can effectively guarantee filter effect, and filter bag and the service life of vacuum extractor；
Two, pressure-detecting device is arranged on the upper port of communicating pipe, is possible to prevent the accuracy of liquid attachment impact detection numerical value, it is ensured that equipment safety runs；
Three, vacuum extractor is closed in time when blocking serious, it is ensured that its service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
