However, the first positioning rod and the second positioning rod of this application both require fastening nuts for installation. The installation of the fastening nuts requires a certain amount of time to tighten the fastening nuts, thereby increasing the time required for installing multiple mixer blades and reducing the installation efficiency of the mixer blades.

[0011] In a preferred example, the present invention can be further configured as follows: two grooves are provided on the top side of the arc-shaped plate, and the bottom sides of the two clamping rods are respectively embedded in the corresponding grooves.

[0012] In a preferred example, the present invention can be further configured as follows: a positioning shaft is connected to the center of the bottom side wall of each of the two positioning holes, and a positioning groove is opened at the bottom end of each of the two limiting shafts, and the positioning shaft is inserted into the positioning groove.

DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Example:

[0029] Reference Figures 1-6 The present invention discloses a mixing device for producing ethylene glycol phenyl ether, comprising an outer tube body 1, a static mixing plate 1 2, and a static mixing plate 2 3. The top side of the outer tube body 1 is provided with two positioning holes 4, and the inner circumference of the two positioning holes 4 is provided with a notch 5. The positioning holes 4 are connected to the outer tube body 1 through the notch 5, and the two positioning holes 4 are provided with a limiting member 6.

[0030] The limiting member 6 includes a limiting shaft 7, a wide groove 8, a narrow groove 9, a sliding rod 10, a slide plate 11 and a clamping rod 13. The limiting shaft 7 is inserted into the positioning hole 4. The wide groove 8 is opened on the top side wall of the outer tube body 1. The narrow groove 9 is opened on the inner side wall of the wide groove 8. The sliding rod 10 is slidably installed in the narrow groove 9. The slide plate 11 is slidably installed in the wide groove 8. The end of the sliding rod 10 extends into the wide groove 8 and is connected to the side of the slide plate 11. The sliding rod 10 and the narrow groove 9 are dynamically sealed. The clamping rod 13 is fixedly connected to the top end of the slide plate 11.

[0031] An arc-shaped plate 14 is connected between the top side outer peripheral walls of the two limiting shafts 7, the clamping rod 13 is L-shaped, the top side wall of the arc-shaped plate 14 is in contact with the bottom side wall of the clamping rod 13, and the outer peripheral sides of the two limiting shafts 7 are respectively connected to the sides of the static mixing plate 1 2 and the static mixing plate 2 3.

[0032] In this embodiment, when in use, the static mixing plate 1 2 and the static mixing plate 2 3 are multiple and stacked on each other. In addition, the sides of the static mixing plate 1 2 and the static mixing plate 2 3 are fixedly connected to the outer circumference of the two limiting shafts 7, and then an arc-shaped plate 14 is connected between the ends of the two limiting shafts 7, thereby achieving the effect of limiting the limiting shaft 7 and the static mixing plate 1 2 and the static mixing plate 2 3 respectively.

[0033] After the static mixing plate 1 2 and the static mixing plate 2 3 are connected to the limiting shaft 7, the two limiting shafts 7 are vertically inserted into the corresponding positioning holes 4. The positioning holes 4 are connected to the outer tube body 1 through the notches 5. This prevents the static mixing plate 1 2 and the static mixing plate 2 3 from being blocked by the inner wall of the outer tube body 1 when they are inserted into the outer tube body 1 after being connected to the limiting shafts 7. Then, the limiting shafts 7 are inserted into the bottom ends of the corresponding positioning holes 4.

[0034] Then, the two clamping rods 13 are released, and the air pressure in the narrow groove 9 will push the slide bar 10 and drive the slide bar 11 to move, and finally the clamping rod 13 will move to the top of the curved plate 14, thereby achieving the effect of positioning the curved plate 14.

[0035] In a further preferred embodiment of the present invention, Figure 3 As shown, the wide groove 8 , the narrow groove 9 , the slide bar 10 and the slide plate 11 are all arranged in an arc shape, and the curvature is the same as the curvature of the outer peripheral side of the outer tube body 1 .

[0036] In this embodiment, the wide groove 8, narrow groove 9, slide rod 10 and slide plate 11 are all arc-shaped, and the curvature is the same as that of the outer tube body 1, so that when the slide rod 10 and the slide plate 11 slide, they slide in the wide groove 8 and the narrow groove 9 respectively, so that the clamping rod 13 can limit the arc plate 14 with the largest fitting area, thereby improving the stability of the arc plate 14 when it is limited by the clamping rod 13.

[0037] In a further preferred embodiment of the present invention, Figure 4-5 As shown, a positioning shaft 16 is connected to the center of the bottom side wall of the two positioning holes 4 , and a positioning groove 17 is formed at the bottom end of the two limiting shafts 7 , and the positioning shaft 16 is inserted into the positioning groove 17 .

[0038] In this embodiment, the positioning shaft 16 is fixedly connected to the bottom of the positioning hole 4. After the corresponding limiting shaft 7 is inserted into the positioning hole 4, the limiting shaft 7 can be sleeved on the positioning shaft 16, thereby limiting the bottom of the limiting shaft 7 and improving the stability of the bottom of the limiting shaft 7.

[0039] In a further preferred embodiment of the present invention, Figure 4-5 As shown, the top ends of the two positioning shafts 16 are connected to limiting springs 18 , and the top ends of the limiting springs 18 are in contact with the top side walls of the positioning grooves 17 .

[0040] In this embodiment, the spring is set so that after the limiting shaft 7 is inserted into the positioning hole 4, the spring will be squeezed by the top side wall of the positioning groove 17. After the arc plate 14 is limited by the clamping rod 13, the reaction force of the spring will push the limiting shaft 7, so that the limiting shaft 7 is subjected to the pushing force applied by the spring, thereby increasing the squeezing force between the limiting shaft 7 and the clamping rod 13, and improving the friction between the clamping rod 13 and the arc plate 14, thereby avoiding the clamping rod 13 from shaking when mixing ethylene glycol phenyl ether, thereby affecting the stability of the limitation of the arc plate 14.

[0041] In a further preferred embodiment of the present invention, Figure 1-3 As shown, two grooves 15 are formed on the top side of the arc-shaped plate 14 , and the bottom sides of the two clamping rods 13 are respectively embedded in the corresponding grooves 15 .

[0042] In this embodiment, when the groove 15 is in use, the limiting shaft 7 is pushed by the spring, which causes the arc plate 14 to move upward, so that the groove 15 wraps the clamping rod 13, further limiting the position of the clamping rod 13, and improving the stability of the clamping rod 13 after limiting the arc plate 14, so that the arc plate 14 and the clamping rod 13 limit each other.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
