The molding machines for pulp molding are fully-automatic molding machines for pulp molding, and the intermittent drainage vacuum devices are middle gas-water separation double-tank intermittent drainage vacuum devices; the positive and negative pressure pipes of the plurality of fully-automatic molding machines for pulp molding are provided with vacuum pipes which are connected with large-diameter horizontal pipes, the outlets of the large-diameter horizontal pipes are connected with gas-water separation large-diameter pipes in the middle to allow the plain boiled water to return to the middle gas-water separation large-diameter pipes in the molding vacuum pipes, gas-water separation is performed in the pipes, and the plain boiled water flows into water drainage tanks directly to allow a negative pressure storage tank to keep maximum gas storage capacity all the time; and after water is drained completely, a single drainage tank, which has a small volume, enters a water storage state with small air volume for balancing pressure, so the balancing time is reduced, the pressure drop fluctuation quantity is reduced and the molding and absorbing of paper pulp fibers are performed under a stable negative pressure.
Description
Technical field
The present invention relates to the paper mould equipment technical field, specifically is the device with fully-automatic molding machine for pulp molding and intermittent drainage vacuum devices.
Background technology
At present, be engaged in the equipment that moulded paper pulp product is produced, relate generally to following three cover important device: the make-up machine of formed product, dry trimmer and intermittent drainage vacuum devices.Above-mentioned traditional device has the following disadvantages: (1) has traditional moulded paper pulp product make-up machine now, and the drying cost of its product is a link that accounts for the production cost maximum ratio; Yet, on the production equipment of existing moulded paper pulp product, also fail mechanical energy this technology of dewatering of utilizing of economy the best is applied on the former, therefore, in the production cost comparison of product inner packing, the paper fibre is compared with the production cost of EPS goods, still than higher.The expensive link of reflection mainly on this link of product drying, makes the environment-friendly materials product of this type of renewable recycle in the paper pulp fiber packing articles, has lost price competitiveness, can not replace the packing articles of EPS material (non-degradable) in a large number; Therefore, the dewatering process that makes full use of mechanical energy and negative pressure is removed a large amount of moisture in the moulded paper pulp product, the high energy consumption drying, the production efficiency that exist in the prior art are low to overcome, people's labour intensity and the high technical problem of production cost, and this technical problem is thirsted for solving by industry always; (2) make full use of mechanical energy exactly for solving the most economical method of paper mould shaping and drying, remove more moisture, therefore, carrying out a large amount of analysis and research aspect the mechanism of paper pulp fiber plastic suction forming apparatus and the technology application conditions, industry wishes always to utilize that the best mechanical energy of economy is fully dewatered, the fully-automatic molding machine for pulp molding of the integrated function of heat energy drying; (3) equipment of traditional moulded paper pulp product production, all adopt the vacuum plant of single (storage) displacement can structure, intermittent drainage, when inhaling the slurry moulding, plain boiled water through piping suck be connected with vavuum pump on put in the negative pressure holding vessel, go forward side by side promoting the circulation of qi moisture from, after (storage) displacement can of underlying is full of plain boiled water,, drain the plain boiled water in (storage) displacement can by the connecting pipe sealing of valve with two jars; At this moment, continue to inhale the slurry moulding, the plain boiled water that sucks can only temporarily be stored in the negative pressure holding vessel, because (storage) displacement can is sealed by valve, therefore, plain boiled water in the negative pressure holding vessel certain volume that accounted for, the gas storage volume of negative pressure holding vessel is constantly reduced, after displacement can had been arranged plain boiled water, two tank connected valves were opened, and displacement can shifts and is water stored state, need carry out pressure balance soon, make and be stored in (storage) displacement can that the plain boiled water of putting the negative pressure holding vessel flows into underlying temporarily, this moment, vacuum sharply descended, and fluctuating range is bigger up and down for pressure; This periodic pressure fluctuates widely, and moulding absorption paper pulp fiber is under the unsettled condition of negative pressure carries out, and product weight variable occurs, directly influences the quality of product, or prolongs molding time, energy loss; (4) vacuum plant of single (storage) displacement can structure, be plain boiled water at first to be sucked carry out gas-water separation in the negative pressure holding vessel of putting again, in the state that many make-up machines are worked simultaneously, by make-up machine with on put the plain boiled water that has inequality in the negative-pressure pipeline that the negative pressure holding vessel is communicated with, need with putting the negative pressure holding vessel in the negative pressure suction, and the negative pressure of the plastics sucking moulding mould in the make-up machine, because the plain boiled water of negative pressure pipe has played interval action, produce when inhaling the slurry formation mould must pressure drop being input to for the vacuum negative pressure that makes system, therefore, on the vavuum pump power configuration, can only strengthen vavuum pump power and satisfy manufacturing condition, the more energy of meeting loss has increased production cost.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, and the device with fully-automatic molding machine for pulp molding and intermittent drainage vacuum devices is provided; This fully automatic forming machine collection mechanical energy is fully dewatered, the integrated function of heat energy drying, make full use of the dewatering process of mechanical energy and negative pressure, remove large quantity of moisture in the moulded paper pulp product, reach the low energy consumption drying, enhance productivity, reduce the advantage of people's labour intensity and production cost; And, the vacuum plant of this pair jar intermittent drainage has simple and reasonable for structurely, and moulding absorption paper pulp fiber is in all the time under the stable condition of negative pressure and carries out, the formed product quality is good, energy-conservation, can also improve the advantage of the installed capacity more than 30% when need not to strengthen vavuum pump power.
