Description

Technical Field

[0001] The utility model belongs to the field of anti-blocking structures for feed ports, and in particular relates to an anti-blocking filter screen for a PTA continuous plate feed port. Background Art

[0002] Terephthalic acid is an organic compound, a white crystalline solid, soluble in water. Terephthalic acid is one of the isomers of phthalic acid, the other isomer is phthalic acid. Terephthalic acid is widely used in chemical fields such as dyes, plastics, and resins. It is an important raw material for the synthesis of phthalocyanine dyes, and can also be used to produce polymer materials such as polyester resins and polyamides.

[0003] The PTA conveyor chain is an important device for conveying PTA from the feeding port to the PTA silo. Due to equipment modification, the vibrating screen on the top of the silo was removed. During the production process, there is a risk that the broken chain and the PTA rope head will enter the PTA silo. In serious cases, the broken chain will stop the rotating discharge valve, causing equipment damage and affecting normal process production. Therefore, it needs to be improved. Summary of the invention

[0004] The utility model aims to provide a PTA connecting plate feed port filter screen which is anti-blocking, thereby solving the problem that foreign matter may enter the PTA silo during the material conveying process.

[0006] The principle of the utility model is that when in use, the PTA material is fed from the conveying pipe of the feeding port, and then conveyed to the silo from the feeding port after passing through the swivel, and the PTA material will be filtered by the filter screen when passing through the swivel, so that the rope head and the crushing link can be effectively prevented from entering the silo without affecting the feeding amount. In the later stage, it is only necessary to pull the protective cover up and down so that the iron ring on the outside of the protective cover is attracted to the magnetic block, and then pull the pin upward through the pull ring to separate the pin from the plug block, thereby releasing the restriction on the swivel, and then rotate the swivel, and the swivel is rotated by the swivel pin, so that the filter screen can be taken out for cleaning.

[0007] The beneficial effect of the utility model is that a rotatable opening and closing swivel is arranged between the feed port of the silo and the conveying pipe, and a filter supported by a support ring is arranged on the inner side of the swivel. This can effectively prevent rope heads and broken connecting plates from entering the silo without affecting the material discharge amount, and the filter can be easily taken out for cleaning.

[0008] By setting a protective sleeve between the feed port and the conveying pipe, the protective sleeve can be covered on the outside of the rotating ring, and then an iron ring is set on the outside of the protective sleeve, and then the protective sleeve can be fixed by the attraction of the iron ring and the magnetic block, which is convenient for opening and closing of the protective sleeve.

[0009] Furthermore, a support ring is fixedly connected to the inner side of the rotating ring and located below the filter screen, and the support ring is in contact with the filter screen. The setting of the support ring has a supporting effect on the filter screen.

[0010] Furthermore, a slider is fixedly connected to the middle section of the pin body of the bolt, a guide rod is fixedly connected to the inner side of the hollow shell, the guide rod passes through the slider and is slidably connected to the slider, and a spring is sleeved on the outer side of the rod body of the guide rod. The guide rod and the spring cooperate with the slider to provide an elastic guiding effect on the bolt.

[0011] Further, one end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the inner surface of the hollow shell. Through the setting of the spring, the elastic force can be applied to the latch through the slider.

[0012] Furthermore, a protective sleeve is slidably sleeved on the outer side of the delivery pipe, and the inner wall of the protective sleeve is slidably connected to the connecting frame, an iron ring is fixedly connected to the outer side of the protective sleeve, and a slide is fixedly connected to the upper outer side of the delivery pipe, and the slide passes through the iron ring and is slidably connected to the iron ring. The setting of the protective sleeve can play a role in aesthetics.

[0013] Furthermore, a magnetic block is fixedly connected to the vertical portion of the slide, and the magnetic block cooperates with the iron ring to limit the protective sleeve.

[0014] Furthermore, a limiting block is fixedly connected to the bottom of the slide, and the limiting block is in contact with the iron ring. The setting of the limiting block has a limiting effect on the iron ring. BRIEF DESCRIPTION OF THE DRAWINGS
