DETAILED DESCRIPTION

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0031] Example:

[0032] like Figures 1 to 4 As shown, a visual structure of an esterification catalyst filter includes a cylinder 1. The side wall of the cylinder 1 includes a resin inlet 11, a liquid inlet 12 and a resin inlet and outlet 13 from top to bottom. A cone 14 is provided at the bottom of the cylinder 1. A resin outlet 15 is provided at the bottom of the cone 14. A valve is provided below the resin outlet 15 to control whether the resin outlet 15 discharges resin. An observation port 2 is provided on the side of the cylinder 1 above the cone 14.

[0033] In order to ensure the observation effect and the sealing effect after the observation port 2 is set, the specific structure at the position of the observation port 2 is that the observation port 2 extends outward in the horizontal direction to form a fixed frame 21. After the fixed frame 21 is set, the visible protection plate 24 and the sealed visible plate 22 can be avoided to be set in an arc shape. The observation port 2 is set in the center of the fixed frame 21 and passes through the barrel body. The fixed frame 21 is connected to the inside of the barrel body 1. A pressing frame 23 is set outside the fixed frame 21. A sealed visible plate 22 is set between the outside of the fixed frame 21 and the inner side of the pressing frame 23. A visual protection plate 24 is set on the outside of the pressing frame 23. The sealed visible plate 22 plays a role of sealing and visualization, and the visual protection plate 24 mainly plays a role of protection and observation. It should be known that in this embodiment, the visual protection plate 24 and the sealed visible plate 22 can be made of glass or transparent acrylic material. At the same time, the visual protection plate 24 can be replaced by opaque material to meet the light-proof requirements during the resin reaction process.

[0034] like Figure 2 and Figure 4 As shown, a liquid level identification plate 25 is provided on the side of the inner side of the cylinder 1 opposite to the observation port 2. The liquid level identification plate 25 is an annular plate provided on the inner side of the cylinder 1. The liquid level identification plate 25 protrudes from the inner side of the cylinder 1. In the height direction, the liquid level identification plate 25 is located between below the resin inlet and outlet 13 and above the cone 14. There are three liquid level identification plates 25 equidistantly distributed along the inner side of the cylinder 1. The spacing between the liquid level identification plates 25 is 250mm-350mm. In this embodiment, the spacing between the liquid level identification plates 25 in the height direction is 300mm; in the horizontal direction, the liquid level identification plate 25 extends circumferentially around the inner side of the barrel to expand the identification range.

[0035] The visible protection plate 24, the sealed visible plate 22, the fixed frame 21 and the pressing frame 23 can all be circular or rectangular. In this embodiment, the visible protection plate 24, the sealed visible plate 22, the fixed frame 21 and the pressing frame 23 are all rectangular; in order to strengthen the structural strength of the fixed frame 21 and the cylinder 1 at the observation port 2, the cylinder 1 is provided with a structural reinforcement plate 26 on the outside of the fixed frame 21, and the structural reinforcement plate 26 is arranged around the fixed frame 21. A welding seam 27 is provided between the fixed frame 21 and the cylinder 1, and the welding seam 27 extends between the fixed frame 21 and the structural reinforcement plate 26, thereby strengthening the connection effect.

[0036] like Figure 3 As shown, in order to improve the sealing effect of the sealed visual panel 22, a first fixing groove 211 is provided on the outer side of the fixing frame 21, and the first fixing groove 211 is provided around the observation port 2. The first fixing groove 211 is formed by the inward depression of the outer surface of the fixing frame 21. A second fixing groove 231 is provided on the inner side of the pressing frame 23, and the second fixing groove 231 is provided around the observation port 2. The edge of the sealed visual panel 22 is clamped between the first fixing groove 211 and the second fixing groove 231. The first fixing groove 211 and the second fixing groove 231 are both rectangular. At the same time, the first fixing groove 211 and the second fixing groove 231 are embedded with a sealing gasket 212 made of rubber.

[0037] like Figure 3 As shown, a visual port 232 corresponding to the observation port 2 is provided in the pressing frame 23 to improve the visual effect of the pressing frame 23 . The pressing frame 23 is tilted outwardly at the outer side of the visual port 232 to form a guide surface 233 .

[0038] like Figure 3As shown, a first-level pressurized fixing structure 3 is provided between the fixing frame 21 and the pressing frame 23, which plays the role of sealing, pressurizing and fixing the sealing visual panel 22. Its specific structure is that the first-level pressurized fixing structure 3 includes a first threaded hole 31, a buried through hole 32 and a first bolt 33, wherein the buried through hole 32 has a T-shaped longitudinal section to ensure that the end of the first bolt 33 does not protrude from the surface of the pressing frame 23, and a first threaded hole 31 is provided at each of the four corners of the fixing frame 21, and the buried through holes 32 are also provided at the four corners of the pressing frame 23. The buried through holes 32 correspond to the first threaded holes 31, and the first bolt 33 passes through the buried through hole 32 and is threadedly connected to the first threaded hole 31. By rotating the first bolt 33, the first fixing groove 211 and the second fixing groove 231 clamp the sealing visual panel 22.

[0039] In order to fix and reinforce the visual protection plate 24 hanging outside the pressing frame 23, as shown Figure 3 As shown, a secondary pressurized fixing structure 4 is arranged between the visible protection plate 24, the pressing frame 23 and the fixing frame 21. The specific structure of the secondary pressurized fixing structure 4 is that the secondary pressurized fixing structure 4 includes a second threaded hole 41, a through hole 42 and a second bolt 43. The second threaded hole 41 is arranged above the fixing frame 21 and is located between adjacent first threaded holes 31 in the horizontal direction, which plays a role in avoiding the first threaded hole 31. The through hole 42 is arranged above the pressing frame 23 and is located between adjacent buried through holes 32 in the horizontal direction, which plays a role in avoiding the buried through hole 32. The second bolt 43 passes through the through hole 42 and is connected with the second threaded hole 41.

[0040] like Figure 2 and Figure 3 As shown, a light blocking plate 234 is provided on one or both sides of the pressing frame 23. The light blocking plate 234 extends outward in the horizontal direction, mainly to prevent the side light from reflecting on the surface of the visual protection plate 24 or the sealed visual plate 22, affecting the observation of the interior of the cylinder 1.

[0041] Working principle:

[0042] Resin is injected into the cylinder 1 through the resin inlet 11, and liquid is injected through the liquid inlet 12 at a constant rate and quantity according to process requirements. During process debugging or normal production flow, the operator observes the interior of the cylinder 1 through the sealed visual panel 22 through the visual protection plate 24 (or when high shading requirements are required, the second bolt 43 can be opened to remove the opaque visual protection plate 24), and the liquid level identification plate 25 opposite the sealed visual panel 22 to see if the liquid level is at the position of the upper, middle and lower liquid level identification plates 25. At the same time, the residual amount of resin and the liquid stratification above the filter cone 14 are observed. When the resin is too little or too much, it will not affect normal discharging, and the resin can be replenished or extracted through the resin inlet and outlet 13 located just above the liquid level identification plate 25.
