Summary of the invention
The purpose of this utility model is to overcome above deficiency, and provide a kind of structure simple, power consumption rate is low, and floor space is little, easy to maintenance, pollution-free to Working environment, and filtrate can be recycled, and reduces the vacuum dewatering system of a kind of gypsum slurries of energy consumption.
The purpose of this utility model is achieved through the following technical solutions: a kind of vacuum dewatering system of gypsum slurries, comprise vacuum tank, vacuum tank is connected with Backwash pipeline, Backwash pipeline is provided with the first pneumatic ball valve, vacuum tank is separately connected with filtrate conduit, filtrate conduit is provided with the second pneumatic ball valve, the other end of Backwash pipeline and filtrate conduit is all contained on distribution valve, vacuum tank has feeding pipe, feeding pipe is provided with the first valve, vacuum tank is provided with pressure unit and intake ducting, intake ducting is provided with the second valve, gas pipeline is connected with vacuum pump, vacuum pump is provided with outlet pipe, vacuum tank bottom is provided with discharge valve, vacuum tank top is provided with vacuum meter.
Further improvement of the utility model is: vacuum tank is provided with liquidometer.
Further improvement of the utility model is: feeding pipe end connects the instrument of extraneous loaded material.
Further improvement of the utility model is: Backwash pipeline, filtrate conduit are all connected with vacuum tank by flange with intake ducting.
Further improvement of the utility model is: the first pneumatic ball valve is all connected with filtrate conduit with Backwash pipeline by flange with the second pneumatic ball valve.
Further improvement of the utility model is: intake ducting is all connected with vacuum pump by flange with outlet pipe.
The utility model compared with prior art has the following advantages:
The utility model system architecture is simple, all pipelines all by Flange joint, convenient disassembly, easy to maintenance, and vacuum tank is provided with liquidometer, vacuum meter and pressure unit, these equipment can monitor its use procedure accurately, guarantee use safety; Water in vacuum tank after dehydration, by the magnetism of the washing unit in the external world, water is absorbed distribution valve from Backwash pipeline, then deliver to disk inner filtration room and recycle, such structure water saving, can recycle; When vacuumizing, vacuum pump can only allow water pass through, and the particle in slurries cannot pass through, and ensure that without vacuum leak, greatly reduces energy consumption and material moisture; And this vacuum system floor space is little, structure is simple, when stopping using, can reclaim filtrate by discharge valve.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-vacuum tank, 2-Backwash pipeline, 3-first pneumatic ball valve, 4-filtrate conduit, 5-second pneumatic ball valve, 6-distribution valve, 7-feeding pipe, 8-first valve, 9-pressure unit, 10-intake ducting, 11-second valve, 12-vacuum pump, 13-outlet pipe, 14-discharge valve, 15-vacuum meter, 16-liquidometer, 17-flange.
