Description

Technical Field

[0001] The present application relates to the technical field of hydrophilic resin preparation, and in particular to a polymerization and decomposition device for preparing hydrophilic resin. Background Art

[0002] Hydrophilic resin is a new type of functional polymer material that can absorb hundreds or even thousands of times its own weight of water, and has a good water retention capacity. It does not dehydrate or dehydrates very little under pressure. After the material absorbs water, its water absorption capacity can be restored after drying, and it can be used many times. In addition, hydrophilic resin also has a three-dimensional spatial network structure, is insoluble in water and organic solvents, has the ability to absorb ammonia, urine, blood and organic drugs, and has good fertilizer and drug sustained release properties. Therefore, hydrophilic resin has been widely used in agriculture, forestry, horticulture, physiology and hygiene, food, civil engineering, daily chemical industry, life health care, desert wasteland and coal mine fire prevention. Hydrophilic resin can be classified into starch, fiber and synthetic polymer according to the source of raw materials.

[0003] Hydrophilic resin polymerization is the process of converting the liquid phase of the polymerization monomer reaction liquid into a gel solid phase. At present, one of the equipments for preparing hydrophilic resin is to use an open belt reactor equipment for polymerization production, which requires a horizontal layout of the polymerization transmission line, occupies a large area, resulting in high preparation costs, and after a single polymerization transmission, the material needs to be manually turned over and transferred to the front end of the polymerization transmission line for polymerization again, which is time-consuming and labor-intensive, and the quality of the prepared hydrophilic resin is low. At the same time, the hydrophilic resin needs to be transported for crushing and granulation later, which further increases the manufacturing cost. Utility Model Content

[0040] See also Figure 1 , Figure 1 This is a schematic diagram of the device structure of this application.

[0041] It should be noted that the polymerization monomer reaction solution referred to below may be in a liquid or gel state at different stages of preparation, and those skilled in the art may determine this based on the preparation process.

[0042] The embodiment of the present application provides a polymerization and decomposition device for preparing a hydrophilic resin, including a polymerization unit 300, wherein the polymerization unit 300 is used to continuously polymerize a reaction material 201 to form a hydrophilic resin, and the reaction material 201 includes a reaction bag and a polymerization monomer reaction liquid filled therein.

[0043] Preferably, the polymerization unit 300 is used to provide a polymerization environment at normal temperature and pressure, avoiding the use of high temperature and high pressure equipment, controlling production costs, and improving safety.

[0044] In one embodiment, the polymerization unit 300 includes a multilayer polymerization component 310 and a flip component 320 connecting two adjacent polymerization components 310. The multilayer polymerization components 310 are arranged in sequence along the height direction, which can effectively control the floor area of ​​the polymerization unit 300, thereby controlling the floor area of ​​the equipment and reducing costs. At the same time, the front and back sides of the reaction material 201 are automatically alternated during the movement of the reaction material 201, which effectively improves the polymerization uniformity of the reaction material 201, saves time and effort, and improves the quality of the hydrophilic resin.

[0045] The polymer unit 300 may include 2-10 layers of polymer components 310, such as 2 layers, 3 layers, 5 layers, or 10 layers.

[0046] Specifically, the polymerization component 310 is used to move and polymerize the reaction material 201, so that the polymerization monomer reaction liquid in the reaction material 201 is polymerized to form a hydrophilic resin.

[0047] The flipping assembly 320 is used to flip and move the reaction material 201 between two adjacent polymerization assemblies 310 , so that the front and back sides of the reaction material 201 are alternately placed in the two adjacent polymerization assemblies 310 .

[0048] In one embodiment, the polymerization assembly 310 includes a second transmission line 311 and a second ultraviolet lamp 312. The second transmission line 311 is arranged horizontally, and the second ultraviolet lamp 312 is arranged above the second transmission line 311, so that the reaction material 201 initiates a polymerization reaction through the ultraviolet radiation ionization effect, and passes through the multi-layer polymerization assembly 310 to achieve a polymerization reaction that lasts for a long time, and finally forms a stable gel state, that is, a hydrophilic resin.

[0049] It is understandable that in order to achieve the ionization effect of ultraviolet radiation to initiate the polymerization reaction, the reaction bag used for the reaction material 201 can be penetrated by ultraviolet light, and a transparent reaction bag is preferably used.

[0050] In one embodiment, the multi-layer polymer assembly 310 is used to move the reaction material 201 layer by layer from low to high, and the transmission rate of the plurality of second transmission lines 311 in the multi-layer polymer assembly 310 increases with the height, so as to achieve continuous and stable movement of the reaction bag in the height direction, thereby ensuring the preparation stability and quality. The increase ratio is preferably 5-10%, and further 6-8%.

[0051] In one embodiment, the turning assembly 320 includes a transfer member and a stopper. The transfer member is used to connect with two adjacent polymerization assemblies 310 and cooperate with the stopper to clamp and drive the reaction material 201 to turn over and move.

[0052] This method improves the reliability of the flipping component 320 flipping the reaction material 201 on a polymerization component 310 and moving it to the adjacent upper layer polymerization component 310 through the cooperation of the limiting component and the transfer component, thereby ensuring the preparation stability and quality.

[0053] In one embodiment, the transfer member is an arc-shaped third transmission line 321 , and both ends of the third transmission line 321 are respectively connected to two adjacent polymerization components 310 , that is, when the polymerization component 310 includes a second transmission line 311 , both ends of the third transmission line 321 are respectively connected to two adjacent second transmission lines 311 .

[0054] The position-limiting member is a flip wheel 322 disposed inside the third transmission line 321 , and the center of the flip wheel 322 coincides with the bending center of the third transmission line 321 .

[0055] The third transmission line 321 and the turning wheel 322 cooperate to realize the turning and movement of the reaction material 201, and the structure is simple, the installation is convenient, and the operation is reliable.

[0056] In other alternative embodiments, both the transfer member and the limiting member are transmission lines that are curved in an arc shape, and the bending centers of the two coincide.

[0057] In one embodiment, the third transmission line 321 is integrally formed with the lower one of the two adjacent second transmission lines 311, that is, a transmission line is used, and its end extends to a distance above the higher one, thereby improving the stability of the reaction material 201 entering the higher position polymerization assembly 310 from the flip assembly 320. For example, the third transmission line 321 and the second transmission line 311 are both transmitted by rollers.

[0058] In one embodiment, the device further includes a stabilizing unit 400, which is disposed at the front end of the polymerization unit 300, that is, the reaction material 201 first enters the stabilizing unit 400 and then enters the polymerization unit 300. The stabilizing unit 400 is used to convert the polymerization monomer reaction liquid in the reaction material 201 from liquid to gel state, so that the reaction material 201 entering the polymerization unit 300 can achieve a stable state, and avoid the reaction material 201 being greatly separated from the original position relative to the reaction bag during the flipping process of the polymerization unit 300, resulting in low quality of the prepared hydrophilic resin, or even unable to flip and move to achieve the preparation of the hydrophilic resin.

[0059] Specifically, the stabilization unit 400 may include a first transmission line 410 and a first ultraviolet lamp 420. The first transmission line 410 is horizontally arranged and used to transmit the reaction material 201 to the polymerization unit 300. The first ultraviolet lamp 420 is arranged above the first transmission line 410, so that the reaction material 201 initiates a polymerization reaction through the ultraviolet light irradiation radiation ionization effect, and initially changes from a liquid to a gel state.

[0060] In one embodiment, the first transmission line 410 and the second transmission line 311 of the bottom polymerization assembly 310 are integrally formed, that is, one transmission line is used, thereby improving the stability of the reaction material 201 being transmitted from the stabilization unit 400 to the polymerization unit 300.

[0061] In one embodiment, the equipment further includes a crushing and granulating unit 500, which is disposed at the end of the polymerization unit 300 and is used to crush and granulate the hydrophilic resin generated by the polymerization unit 300 for subsequent processing. The crushing and granulating unit 500 is disposed at the end of the polymerization unit 300 and directly crushes and granulates the generated hydrophilic resin without the need for transportation, thereby reducing costs.

[0062] In one embodiment, the de-granulation unit 500 includes a sequentially arranged unpacking machine 510 , a strip cutter 520 , and a granulation assembly 530 .

[0063] The unpacking machine 510 is used to remove the reaction bag in the reaction material 201 for subsequent processing. Referring to A, the stripping machine 520 is used to cut the hydrophilic resin into multiple strips along the transmission direction.

[0064] There are multiple granulation components 530, and they correspond one-to-one to multiple hydrophilic resins, that is, one granulation component 530 corresponds to one hydrophilic resin, so as to improve the pulverization effect.

[0065] In one embodiment, the unpacking machine 510 includes an unpacking transmission line 511, a first cutting member, and a separating member 512. The unpacking transmission line 511 is connected to the end of the polymerization unit 300. Two first cutting members are provided, and are respectively provided on both sides of the unpacking transmission line 511 to split the two sides of the reaction bag in the reaction material 201. Two separating members 512 are provided, and are respectively provided on both sides of the end of the unpacking transmission line 511 to separate the reaction bag divided into two parts from the hydrophilic resin.

[0066] For example, two first cutting pieces are respectively arranged on the left and right sides of the unpacking transmission line 511 to divide the reaction bag in the reaction material 201 into two upper and lower parts, and two separating pieces 512 are respectively arranged on the upper and lower sides of the end of the unpacking transmission line 511 to separate the reaction bags in the upper and lower parts from the hydrophilic resin respectively.

[0067] The separating member 512 may be a rotating drum, so as to roll up the reaction bag divided into two parts separately.

[0068] In one embodiment, the strip cutter 520 includes a plurality of clamp conveyor belts and a second cutting member 523 disposed between two adjacent clamp conveyor belts, the clamp conveyor belts are used to clamp and convey the hydrophilic resin up and down, and the second cutting member 523 is used to cut the hydrophilic resin into multiple strips along the transmission direction.

[0069] In one embodiment, the clamp conveyor belt includes a lower conveyor belt 521, an upper conveyor belt 522 and a reset member, and the reset member acts on the upper conveyor belt 522 so that the upper conveyor belt 522 has a tendency to move toward the lower conveyor belt 521 to clamp the hydrophilic resin, thereby further improving the slitting effect.

[0070] The reset member can be a cylinder, a spring, etc.

[0071] In one embodiment, the granulation assembly 530 includes a plurality of granulators 531 arranged in sequence along the height direction, and the inlet of the granulator 531 of the next stage corresponds to the outlet of the granulator 531 of the previous stage. The granulation particle size of the plurality of granulators 531 becomes finer step by step as the height decreases, thereby meeting the particle size requirement. In addition, they are arranged along the height direction in the same manner as the polymerization unit 300, which can save floor space and thus control costs.

[0072] The granulator 531 may be an extrusion granulator 531 or an extrusion granulator 531 .

[0073] Furthermore, the multi-layered polymerization components 310 arranged in sequence from low to high and the multiple granulators 531 arranged in sequence from high to low effectively utilize the space and comply with the preparation process.

[0074] In one embodiment, the device further includes a continuous feeding unit 100 and a continuous discharging unit 200 .

[0075] The continuous feeding unit 100 is used to continuously supply the polymerization monomer reaction liquid to the continuous discharging unit 200 .

[0076] The continuous discharging unit 200 is used to continuously fill the polymerization monomer reaction liquid into a continuous reaction bag with a closed end to form a continuous reaction material 201.

[0077] At this time, the equipment realizes continuous feeding to the polymerization unit 300 through the continuous feeding unit 100 and the continuous discharging unit 200, so that the reaction material 201 is continuous in a strip shape and is only cut off after a single preparation is completed (the reaction bag is cut off and sealed), that is, there is only one strip of reaction material 201 in a single preparation process, thereby improving production efficiency.

[0078] In other alternative embodiments, the reaction material 201 has a preset length, that is, each reaction bag is independent, and there are multiple bags of reaction material 201 in a single preparation process.

[0079] In one embodiment, the continuous feeding unit 100 includes a plurality of liquid storage tanks 110 and a feeding pipeline 120 .

[0080] The liquid storage tank 110 is used to contain the polymerization monomer reaction liquid. A plurality of liquid storage tanks 110 are connected in parallel in the feed pipeline 120 and feed alternately. The liquid storage tank 110 is connected to the feed pipeline 120 via a switch valve 111 to achieve feed control.

[0081] The feed pipeline 120 is also connected in series with an interlocked delivery pump 121 and a mass flow meter 122 to deliver at a constant flow rate to ensure subsequent uniform generation of the reaction material 201.

[0082] In addition, this method can realize continuous feeding to the continuous discharging unit 200 by alternately feeding the multiple liquid storage tanks 110, thereby improving the production capacity, and has a simple structure and reliable continuous feeding.

[0083] In one embodiment, the liquid storage tank 110 is provided with a liquid level sensor 112, and the liquid level sensor 112 is interlocked with the switch valve 111, so that when the liquid level sensor 112 detects that the polymerization monomer reaction liquid in the liquid storage tank 110 reaches a preset minimum amount, the switch valve 111 is closed, and the switch valve 111 of another liquid storage tank 110 is opened to achieve continuous feeding.

[0084] In one embodiment, the feed line 120 is a circulation line, and the liquid storage tank 110 is also connected to the feed line 120 through a reflux valve. The reflux valve is used to connect the feed line 120 and the liquid storage tank 110 to allow the polymerization monomer reaction liquid to reflux when it is impossible to feed the continuous discharging unit 200. For example, the valve between the continuous feeding unit 100 and the continuous discharging unit 200 is closed. In order to avoid stagnation of the reaction liquid in the feed line 120, the reflux valve can be opened so that the reaction liquid can reflux into the liquid storage tank 110.

[0085] In one embodiment, the continuous discharge unit 200 includes a reaction bag forming mechanism and a filling machine 210. The reaction bag forming mechanism is used to provide continuous reaction bags, and the reaction bags are placed at the discharge port of the filling machine 210. The filling machine 210 is connected to the feed pipeline 120 through the liquid inlet valve 211, and is used to continuously fill the reaction bag with the polymerization monomer reaction liquid to generate the reaction material 201.

[0086] In this method, continuous reaction bags are prepared synchronously with the continuous discharge of the filling machine 210 by the reaction bag forming mechanism, thereby generating the reaction material 201, realizing the continuous preparation of the hydrophilic resin and improving the production capacity.

[0087] In one embodiment, the outlet end of the continuous discharging unit 200 is vertically disposed relative to the first transmission line 410, and a guide member 220 is disposed therebetween.

[0088] The guide member 220 includes a first guide portion 221 and a second guide portion 222 arranged from top to bottom. The first guide portion 221 is in a trumpet shape with an opening facing upward. The second guide portion 222 is connected to the end of the first guide portion 221 and has a guide surface facing the first transmission line 410 .

[0089] This method can guide the reaction material 201 generated by the continuous discharge unit 200 to the first transmission line 410 of the stabilization unit 400, thereby improving the transfer reliability of the reaction material 201. In particular, when the reaction material 201 contains liquid reaction liquid, the reliable transfer of the guide member 220 can also improve the stability of the morphology of the reaction material 201, thereby improving the quality of the prepared hydrophilic resin.

[0090] In one embodiment, a liquid receiving tank 430 is disposed below the first transmission line 410 to cope with the situation where the reaction bag in the stabilization unit 400 is damaged and the reaction liquid leaks out, thereby improving production safety and reducing losses.

[0091] Preferably, the liquid receiving tank 430 is connected to the continuous feeding unit 100 through a pipeline.

[0092] When the continuous feeding unit 100 includes a plurality of liquid storage tanks 110 , the liquid contact tank 430 may communicate with the plurality of liquid storage tanks 110 through a pipeline and a corresponding valve.

[0093] In one embodiment, the reaction bag forming mechanism includes a plurality of film rolling frames, a guide mechanism and a heat sealing machine.

[0094] The film roll rack is used to install the film roll. For example, two film roll racks can be set up, and the film roll A and the film roll B can be placed respectively, and continuous and uninterrupted production can be achieved through the two film rolls. It can be understood that when the film is changed, that is, when the film roll A is about to be used up, its end needs to be connected to the front end of the film roll B, as shown in B.

[0095] The guide mechanism and the heat sealer are both arranged near the discharge port of the filler 210, and the guide mechanism is used to unfold the roll film and drive its two opposite sides to cover the circumference of the discharge port of the filler 210, and the heat sealer is fixedly connected to form a reaction bag, that is, as shown at C, the heat sealer longitudinally fixes the roll film to form a reaction bag. It is understandable that, as shown at D, the bottom of the reaction bag needs to be fixedly connected.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
