Abstract
The invention discloses a metering device of a foaming machine. The metering device consists of a plurality of metering pumps and is connected between two or more material storage tanks and a mixing head of the foaming machine, wherein the material storage tanks are communicated with the mixing head through respective feed pipelines respectively; the metering pumps are penetratively arranged on all feed pipelines; the feed pipeline corresponding to each material storage tank is a double-path pipeline; and each path of pipeline of the feed pipeline is provided with one metering pump. The functions of the foaming machine are increased; different metering pumps can be selectively started according to different products; the device is more flexible to produce and manufacture; and the production cost is also reduced.
Description
Technical field
The present invention relates to a kind of metering device that is used for industrial manufacturing equipment liquid conveyance conduit, relate in particular to a kind of in the production of various model heat-insulating pipe the polyurethane high pressure foaming machine carry out the metering device of rational proportion raw materials mixed conveyance conduit.
Background technology
As shown in Figure 1, at present the polyurethane high pressure foaming machine general adopt two storage tanks and with its one to one two measuring pumps control as system.From raw material, place isocyanates and polyalcohol respectively in these two storage tanks, according to the difference of making the heat-insulating pipe model, be connected with two high-pressure metering pumps or two low-temperature measurement pumps respectively by filter outlet, two groups of raw materials are by sending to fully mixing in the mixing head behind the measuring pump separately, inject die cavity, foaming.
But in manufacturing process, the shortcoming of this structure is found gradually: the restriction of metered pump size model when making the different-diameter heat-insulating pipe, when adopting two measuring pumps to connect the heat-insulating pipe of making little diameter, select the low-temperature measurement pump of small dimension model for use, but restrictedly can not produce large diameter heat-insulating pipe.And when the high-pressure metering pump that adopts big specifications and models is made the heat-insulating pipe of minor diameter, increased cost again, increased energy consumption.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of novel foaming machine metering device, to satisfy the required flexibly of various model different-diameter heat-insulating pipes productions.
Technical solution of the present invention is: a kind of metering device of foaming machine, described metering device is made of a plurality of measuring pumps, be connected between the storage tank and mixing head of foaming machine, described storage tank is two or more, feed pipe by separately is communicated to mixing head respectively, each measuring pump is connected on whole feed pipes, it is characterized in that: with the pairing feed pipe of each storage tank be the two-way pipeline, and on each road pipeline of feed pipe a measuring pump is set respectively.
Preferably, be respectively equipped with filter on the feed pipe between described storage tank and the mixing head, and each measuring pump of described metering device all is arranged at the back segment of the relative filter of feed pipe.
More preferably, described foaming machine contains two storage tanks that are communicated to mixing head respectively by feed pipe, and described metering device has four measuring pumps, is arranged at one by one respectively on four road pipelines of two feed pipes.
The present invention has increased the foaming machine function, can open different measuring pumps according to the different choice of producing product, manufactures more flexibly, and production cost decreases.
Description of drawings
Fig. 1 is the syndeton schematic diagram of foaming machine metering device prior art;
Fig. 2 is the syndeton schematic diagram of foaming machine metering device of the present invention.
The specific embodiment
Below in conjunction with the embodiment accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
As shown in Figure 2, be the syndeton schematic diagram of foaming machine metering device one embodiment of the present invention.As shown in FIG., this foaming machine is the polyurethane high pressure foaming machine that is used to produce heat-insulating pipe, have two component units of the most basic storage tank and mixing head, it also comprises the metering device that is made of a plurality of measuring pumps, is connected between the storage tank and mixing head of foaming machine.Illustrating this foaming machine storage tank is two, comprise second storage tank 12 that is used to store first storage tank 11 of isocyanates and is used to store polyalcohol respectively, feed pipe 31,32 by separately is communicated to mixing head 2 respectively, and is equipped with independently filter 4 on each follow-up pipe material.Be different from the foaming machine metering device syndeton schematic diagram of prior art shown in Figure 1, foaming machine of the present invention and the pairing feed pipe of each storage tank are the two-way pipeline.Corresponding to first storage tank 11, the back segment of its feed pipe 31 relative filters is communicated with respectively and is provided with measuring pump 51,52; And corresponding to second storage tank 12, the rear end of its feed pipe 32 relative filters then is communicated with respectively and is provided with measuring pump 53,54, and those measuring pumps are low-temperature measurement pump cheaply, and its single cost is near 1/2nd high-pressure metering pumps.In carrying out the heat-insulating pipe production process, to four measuring pump central system controls, when foaming machine will be produced large-scale heat-insulating pipe, need four low-temperature measurement pumps are started together, when needs are produced small-sized heat-insulating pipe, only need start two measuring pumps.Like this, can open different measuring pumps according to the different choice of producing product, make the manufacturing more flexible, production cost also decreases.
