Description

Technical Field

[0001] The utility model belongs to the technical field of condensation equipment, in particular to a condensation device for the production of polyurethane resin. Background Art

[0002] Polyurethane resin is a polymer compound, known as the "fifth largest plastic". It is widely used in many fields of the national economy due to its excellent performance. During production, in order to make it form quickly, condensation treatment is often carried out to improve production efficiency.

[0003] At present, the existing condensation equipment used in the actual production of polyurethane resin mostly performs heat exchange through the outside. However, it takes a certain amount of time for the condensation effect from the outside to the inside to be transmitted, which results in the material in the center of the pipeline not being able to achieve sufficient condensation effect in time, affecting the subsequent production quality.

[0004] In order to solve the above problems, the present application proposes a condensing device for producing polyurethane resin. Utility Model Content

[0005] The purpose of the utility model is to provide a condensing device for producing polyurethane resin, which solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a condensation device for the production of polyurethane resin, comprising: a feed pipe and an extension pipe, the extension pipe is installed inside the extension pipe through upper and lower flange mechanisms; an outer condensation pipe is arranged on the outer side of the extension pipe, a convex seat and an upper ring seat above the convex seat are arranged on the upper end, and the inner condensation pipe inside the extension pipe cooperates with the outer condensation pipe to form an internal and external double condensation treatment for the polyurethane resin to promote the condensation rate; an extension portion and a suction pipe and a feeding pipe inside the upper ring seat are arranged on one side of the upper ring seat, the suction pipe is connected to the first branch pipe inside the inner condensation pipe to extract condensed water from its bottom area, and the feeding pipe is connected to the second branch pipe inside the inner condensation pipe to apply condensed water to the area above it, and the stability of the condensation effect of the inner condensation pipe is maintained through this cooperation.

[0008] Furthermore, the condensation plate located inside the extension tube near the lower end is connected to the lower end area of ​​the inner condensation tube to expand the condensation range of the polyurethane resin.

[0009] Furthermore, the interior of the condensation tray is evenly provided with material mixing pipes to increase the contact area, and the interior of the condensation tray forms bulk holes to flow the polyurethane resin, while preventing the polyurethane resin from agglomerating in large quantities and affecting the condensation effect of the internal area.

[0010] Furthermore, a plurality of positioning holes are evenly distributed in the adjacent outer areas of the boss and the upper ring seat along the axial direction of the extension tube.

[0011] Furthermore, a flow diverter seat is provided inside the upper ring seat and a flow guide platform is provided outside the upper ring seat, which are used to divert the polyurethane resin through the positioning hole and introduce it into the interior of the extension tube.

[0012] Furthermore, the guide platform is an inclined structure with a high interior and a low exterior, and the positions of both ends are higher than the central area, so that the polyurethane resin flows directly to the positioning holes to prevent it from remaining in the gap.

[0013] Furthermore, the circumferential distribution of the positioning holes is also used to reserve installation space for the extension part to form a staggered structure.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can directly perform condensation treatment on the inside of the polyurethane resin by adding an inner condensation tube, and at the same time cooperate with the outer condensation tube to form an inner and outer double-layer condensation treatment. Compared with the existing condensation method, the utility model can quickly achieve a sufficient condensation effect on the polyurethane resin transported in the pipeline, so as to adapt to the transportation operation of the pipeline and ensure the production quality of the product;

[0016] The utility model can use the first branch pipe to extract condensed water in the bottom area by means of the oblique installation of the extension part while the polyurethane resin is condensed in the inner condenser. The water level is lowered at this time, and the cooled condensed water is then re-injected into the bottom area by means of the second branch pipe. A circulation is formed in this way, and the temperature of the condensed water in the upper area can be maintained, thereby ensuring stable performance of the condensation treatment for a long time.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] See also Figure 1-4 As shown, the utility model is a condensing device for polyurethane resin production, comprising: a feed pipe 1 and an extension pipe 2, wherein the extension pipe 2 is installed inside the extension pipe 2 through upper and lower flange mechanisms;

[0028] An outer condensation tube 3 is provided on the outer side of the extension tube 2, and a convex seat 5 and an upper ring seat 4 are provided on the upper end thereof. The inner condensation tube 7 inside the extension tube 2 cooperates with the outer condensation tube 3 to form an inner and outer double condensation treatment on the polyurethane resin to promote the condensation rate;

[0029] An extension portion 6 and a suction pipe 8 and a feeding pipe 9 are provided on one side of the upper ring seat 4. The suction pipe 8 is connected to the first branch pipe 10 inside the inner condensing pipe 7 to extract condensed water from the bottom area thereof, and the feeding pipe 9 is connected to the second branch pipe 11 inside the inner condensing pipe 7 to apply condensed water to the area above it, and the stability of the condensation effect of the inner condensing pipe 7 is maintained through this cooperation. Secondly, the adjacent pipe located above one side of the convex seat 5 is used in the same way as the suction pipe 8 and the feeding pipe 9;

[0030] The present embodiment provides a polyurethane transmission pipeline that can perform condensation treatment in both directions inside and outside. The outer circle area and the inner circle area of ​​the polyurethane resin are simultaneously condensed by using the outer condensation tube 3 in cooperation with the inner condensation tube 7, which can greatly improve the condensation efficiency to improve the production quality. At the same time, the condensation water temperature of the area that first contacts the polyurethane resin can be maintained by low-pumping and high-filling method to maintain the stability of the condensation effect for a long time.

[0031] The condensation plate 12 located near the lower end of the extension tube 2 is connected to the lower end area of ​​the inner condensation tube 7 to expand the condensation range of the polyurethane resin and prevent part of the polyurethane resin from being insufficiently condensed.

[0032] Among them, the interior of the condensation plate 12 is evenly provided with material mixing pipes 13 to increase the contact area, and the interior of the condensation plate 12 forms bulk holes 17 to circulate the polyurethane resin, while preventing the polyurethane resin from a large amount of aggregation affecting the condensation effect of the internal area, so as to achieve the effect of sufficient and uniform condensation of the polyurethane resin.

[0033] Among them, multiple positioning holes 14 are evenly distributed in the adjacent outer areas of the boss 5 and the upper ring seat 4 along the axial direction of the extension tube 2. The upper ring seat 4 is provided with a diverter seat 15 and a guide platform 16 on its outer side, which are used to divert the polyurethane resin through the positioning holes 14 and introduce it into the interior of the extension tube 2. The internal positioning holes 14 of the upper ring seat 4 extend outward at an angle to free up structural space in the internal area.

[0034] The guide platform 16 is an inclined structure with a high interior and a low exterior, and the two ends are higher than the central area, so that the polyurethane resin flows directly to the positioning hole 14 to prevent it from remaining in the gap, and is convenient for subsequent cleaning and use.

[0035] The circumferential distribution of the positioning holes 14 is also used to reserve installation space for the extension portion 6 to form a staggered structure.

[0036] It can be understood that the utility model can form a two-way condensation effect on the polyurethane resin inside and outside, accelerate the condensation efficiency, and at the same time maintain the stability of the condensed water in the upper area (the area that first contacts the polyurethane resin) in real time, thereby ensuring the stability of long-term condensation operations.

[0037] A specific application of the operating process of this embodiment is as follows: when in use, first use the diverter seat 15 to cooperate with the guide platform 16 to guide the polyurethane resin to the positioning hole 14 and flow into the extension tube 2. At this time, the outer condensation tube 3 on the outside is used to cooperate with the inner condensation tube 7 on the inside to perform condensation treatment at the same time, so as to form a two-way condensation effect inside and outside, which can accelerate the condensation efficiency and avoid the situation where the inner area cannot fully achieve the condensation effect; further, the first branch pipe 10 is used to cooperate with the suction pipe 8 to extract the condensed water at the bottom of the inner condensation tube 7 and then lower the condensed water level in the area above the inner condensation tube 7, and then the feeding pipe 9 is used to cooperate with the second branch pipe 11 to pour the treated condensed water into the upper area of ​​the inner condensation tube 7 to maintain the stability and constancy of the condensed water in the upper area, so as to ensure the stability of long-term condensation operation.
