Description

Technical Field

[0001] This utility model relates to a phenolic amine curing agent production equipment, specifically a double-layer filter assembly for phenolic amine curing agent production, belonging to the technical field of phenolic amine curing agent production equipment. Background Technology

[0002] Curing agents, also known as hardeners, curing agents, or stabilizers, are substances or mixtures that promote or control curing reactions. They can increase the insolubility and infusibility of products. Curing agents are mainly amines, organic acid anhydrides, and fatty acids. Phenolic amine curing agents are one type. In the production process, the raw materials need to be put into a reaction vessel for processing. Before being put into production, the raw materials often need to be filtered using a filter assembly.

[0003] However, most existing filter assemblies have various problems. For example, in the double-layer filter disclosed in publication number CN108096904A, although it can effectively filter out various impurities with high efficiency and good filtration effect, and the double-layer filter is firmly fixed, improving stability, most current filter assemblies, while achieving the filtration effect, require disassembly and cleaning after a period of filtration to prevent mesh blockage. Currently, the filter often requires screws and other components for fixing, which means that a lot of time is spent tightening the screws during disassembly and assembly. This is cumbersome, time-consuming, and labor-intensive, making it impossible to quickly disassemble and assemble the filter. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] like Figures 1 to 5As shown, a double-layer filter assembly for the production of phenolic amine curing agent includes a feed cylinder 1, a slot 2, a support tray 3, a filter screen 4, and a connecting assembly 5. The slot 2 is disposed in the feed cylinder 1, the support tray 3 is slidably inserted into the slot 2, and the filter screen 4 is disposed on the support tray 3.

[0024] The connecting component 5 is disposed between the slot 2 and the support tray 3, and the connecting component 5 includes a card seat 51, a fixing seat 52, a locking plate 53, a positioning rod 54 and a positioning hole 55. The card seat 51 is fixed in the slot 2, the fixing seat 52 is fixed on the support tray 3, there are two locking plates 53, and the two locking plates 53 are symmetrically fixed on both sides of the fixing seat 52. The positioning rod 54 is slidably connected to the card seat 51, and the positioning hole 55 is disposed on the locking plate 53, and the positioning rod 54 and the positioning hole 55 are respectively configured one-to-one.

[0025] The connecting assembly 5 also includes a linkage rod 56, an abutment 57, and an abutment plate 58. Both the card seat 51 and the fixed seat 52 are provided with mounting cavities. The linkage rod 56 is slidably connected in the fixed seat 52 and is partially located outside the fixed seat 52. The abutment 57 is fixed on the linkage rod 56 at one end located outside the fixed seat 52. The abutment plate 58 is fixed on one end of the positioning rod 54 and is located in the mounting cavity inside the card seat 51. A slot is provided on one side of the card seat 51. The abutment 57 mates with the slot and is engaged in the mounting cavity of the card seat 51. The abutment 57 is partially engaged with the abutment plate 58.

[0026] The connecting assembly 5 also includes a limiting cylinder 510, a pressing rod 511, and a transmission rod 512. There are two limiting cylinders 510, which are symmetrically fixed in the mounting cavity of the fixing seat 52. The two limiting cylinders 510 are provided with sliding grooves near their ends, and the two sliding grooves are staggered. The pressing rod 511 is slidably connected to the support tray 3 and the fixing seat 52, and one end of the pressing rod 511 is rotatably connected to the linkage rod 56. The transmission rod 512 is fixed on the side wall of the pressing rod 511 and is engaged in the sliding groove between the two limiting cylinders 510. One end of the pressing rod 511 is located outside the support tray 3.

[0027] In this utility model, by setting a connecting component 5, the positioning rod 54 in the connecting component 5 is connected to the positioning hole 55, so that the tray 3 can be quickly locked in the slot 2, which facilitates the quick assembly and disassembly of the tray 3 and the guide cylinder 1. At the same time, the transmission rod 512 in the connecting component 5 is linked in the sliding groove at the port of the limiting cylinder 510, so that the abutment 57 can rotate synchronously. The abutment 57 pushes the abutment plate 58, so that the positioning rod 54 and the positioning hole 55 can be quickly connected and separated. At the same time, the limiting and locking effect between the abutment 57 and the card seat 51 further improves the firmness of the connection between the tray 3 and the guide cylinder 1, and prevents the tray 3 and the guide cylinder 1 from separating. Furthermore, the setting of the transmission rod 512 allows the pressing rod 511 to quickly achieve the locking and unlocking effect between the guide cylinder 1 and the tray 3 during the reciprocating movement. It is simple, efficient and practical. Example 2

[0028] like Figures 1 to 5 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0029] A first return spring 59 is fitted on the positioning rod 54. One end of the first return spring 59 abuts against the abutment plate 58, and the other end abuts against the inner wall of the card seat 51. The positioning rod 54 can be quickly reset by the elastic force of the first return spring 59.

[0030] A second return spring 513 is sleeved on the pressing rod 511. The second return spring 513 is located in the mounting cavity of the fixed seat 52, and one end of the second return spring 513 abuts against the fixed seat 52, and the other end abuts against the linkage rod 56. The pressing rod 511 can be quickly reset by the elastic force of the second return spring 513.

[0031] A stop bar is provided in the mounting cavity of the card holder 51, and the stop bar is located on one side of the abutment plate 58. The abutment plate 58 is limited by the setting of the stop bar, so that the abutment head 57 can abut between two adjacent abutment plates 58.

[0032] The overall structure consisting of the tray 3 and the filter screen 4 has at least two sets inside the feed cylinder 1, and the mesh diameters of the two sets of filter screens 4 are different. By passing through the filter screens 4 with different pore sizes, a multi-stage filtration effect can be achieved for the raw materials used in the production of phenolic amine curing agents.

[0033] Working principle: When using this phenolic amine curing agent production equipment, the raw materials for phenolic amine curing agent production are first guided and filtered through the feed cylinder 1 and the filter screen 4. If the filter screen 4 needs to be cleaned during filtration, the pressing rod 511 is pushed. At this time, the transmission rod 512 slides in the groove of the limiting cylinder 510. During the sliding, the limiting effect of the groove drives the linkage rod 56 and the abutment 57 to deflect. At this time, the positioning rod 54 is reset under the elastic force of the first reset spring 59 and separates from the positioning hole 55. At the same time, the abutment 57 can pass through the slot of the card seat 51. At this time, the support tray 3 can be taken out from the card slot 2.
