[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figures 1-6As shown, this utility model provides an aqueous acrylic emulsion reactor with a safety protection mechanism, including a reactor body 1. A geared motor 2 is fixedly installed on the top of the reactor body 1. A rotating shaft 5 is fixedly connected to the output end of the geared motor 2. A support plate 3 is fixedly installed on one end of the rotating shaft 5. Two liquid storage tanks 4 are fixedly installed on the top of the support plate 3. A drain pipe 400 and an inlet pipe are fixedly installed on the outer wall of each of the two liquid storage tanks 4. A sliding groove 600 is opened at the bottom of the support plate 3, and a mixing component 6 and a transmission component 7 are provided. The mixing component 6 includes an anchor stirring rod 603, a cylinder 605, and several mixing blades 604. When the support plate 3 rotates, it drives the anchor stirring rod 603. 3 and several mixing blades 604 rotate. After the cylinder 605 operates, the rotation range of the anchor stirring rod 603 is adjusted. The transmission assembly 7 includes a second cylinder 702, two reciprocating screws 709 and two pusher plates 710. After the cylinder 702 operates, the bearing plate 3 rotates and drives the two reciprocating screws 709 to rotate through the mixing assembly 6. When the reciprocating screws 709 rotate, they drive the pusher plates 710 to slide on the inner wall of the storage tank 4. The outer wall of the vessel body 1 is fixedly installed with a feed pipe 101, a drain valve 102, a water inlet valve 103, a pressure gauge and a thermometer. The drain valve 102 and the water inlet valve 103 are not connected to the inner wall of the vessel body 1. Several docking holes are opened on the top of the vessel body 1.

[0025] Start the geared motor 2. After the geared motor 2 is running, its output end drives the bearing plate 3 to rotate through the rotating shaft 5. After the bearing plate 3 rotates, it drives several mixing blades 604 and anchor stirring rods 603 to rotate. In this way, the mixing effect of the raw materials is improved through various mixing methods. After the mixing rotates for a period of time, first turn off the geared motor 2, then start the cylinder 702, and then start the geared motor 2 again. At this time, the two reciprocating screws 709 rotate accordingly, and cause the two push plates 710 to move vertically upward in the two liquid storage tanks 4. When the push plates 710 move, they push the additives, so that the additives are discharged into the raw materials through the drain pipe 400. In this way, the automatic feeding of various additives is realized. The linkage is strong and it is matched with the mixing degree of the raw materials, which improves the feeding accuracy and improves the applicability.

[0026] After mixing is complete, turn off the geared motor 2 and discharge the material from the reactor. Then start cylinder 605. After cylinder 605 operates, it drives one end of the anchor stirring rod 603 to fit against the inner wall of the reactor 1. Then start the geared motor 2. At this time, the anchor stirring rod 603 can scrape off the material remaining on the inner wall of the reactor 1 when it rotates. After turning off cylinder 605 and geared motor 2, the material can fall off under the action of gravity. The function of the anchor stirring rod 603 can be adjusted by electric control. The anchor stirring rod not only reduces the probability of material remaining on the inner wall of the reactor 1, but also increases the mixing range and has strong applicability.

[0027] The bottom of the vessel body 1 is equipped with a discharge valve. The discharge valve, pressure gauge, temperature gauge, drain valve and water inlet valve are all existing technologies and will not be explained here.

[0028] like Figures 3-4 As shown, in one embodiment, the mixing assembly 6 further includes a rotating rod 602 and a slider 601. A cylinder 605 is fixedly installed at the bottom of the support plate 3. The slider 601 is slidably engaged with the slide groove 600, and one end is fixedly connected to the output end of the cylinder 605. The rotating rod 602 is fixedly connected to the cylinder 605. Anchor-type stirring rod 603 and several mixing blades 604 are all fixedly sleeved on the rotating rod 602. The support plate 3 is rotatably connected to the inner wall of the reactor body 1.

[0029] By limiting the slider 601 through the chute 600, the dynamic slider 601 rotates through the chute 600 when the bearing plate 3 rotates, and the residue on the inner wall of the vessel 1 is scraped off by the anchor-type stirring rod 603, which can effectively improve the utilization rate of materials and improve applicability.

[0030] like Figure 4 and Figure 6 As shown, in one embodiment, the transmission assembly 7 includes a drive gear 706, a first transmission gear 707, a second transmission gear 708, and two rectangular rods 701. After the output end of the second cylinder 702 extends, both the first transmission gear 707 and the second transmission gear 708 can mesh with the drive gear 706. The drive gear 706 is fixedly sleeved on the rotating rod 602. The two rectangular rods 701 are respectively fixedly connected to two reciprocating lead screws 709, and both reciprocating lead screws 709 are rotatably connected to the bearing plate 3. The first transmission gear 707 and the second transmission gear 708 are respectively slidably sleeved on the two rectangular rods 701. On the rectangular rod 701, the transmission assembly 7 also includes a fixed rod 703, a connecting arc plate 1 704 and a connecting arc plate 2 705. The cylinder 2 702 is fixedly installed at the bottom of the bearing plate 3. The fixed rod 703 is fixedly connected to the output end of the cylinder 2 702. The connecting arc plate 1 704 and the connecting arc plate 2 705 are rotatably connected to the transmission gear 1 707 and the transmission gear 2 708 respectively, and are both fixedly connected to the fixed rod 703. The reciprocating screw 709 is rotatably connected to the liquid storage tank 4. The pusher plate 710 is threaded onto the reciprocating screw 709 and slides against the inner wall of the liquid storage tank 4.

[0031] By using a transmission method to link the feeding and mixing processes of additives, the effectiveness of additives can be improved, thereby enhancing the production quality of water-based acrylic emulsions.

[0032] like Figure 2 As shown, in one embodiment, a crash plate 9 is fixedly installed on the outer wall of the vessel body 1, and a protective shell 8 is fixedly installed on the bottom of the support plate 3.

[0033] The anti-collision plate 9 is used to protect the outer wall of the vessel body 1 and improve the protection effect. At the same time, the protective shell 8 can effectively reduce the damage of materials to the transmission components 7 and extend the service life of the equipment.

[0034] The working principle of this water-based acrylic emulsion reactor with safety protection mechanism will be explained in detail below:

[0035] The workers first pour the raw materials to be mixed into the reactor body 1 through the feed pipe 101, then seal the feed pipe 101, and add preservatives, emulsifiers, or other different types of additives to the two storage tanks 4 respectively. Then, they start the geared motor 2. After the geared motor 2 operates, its output end drives the bearing plate 3 to rotate via the rotating shaft 5. The rotation of the bearing plate 3 then drives the rotating rod 602 to rotate via the slider 601. When the rotating rod 602 rotates, it drives several mixing paddles 604 and anchor-type stirring rods 603 to rotate, thereby improving the mixing effect of the raw materials through various stirring methods. After the rotating rod 602 rotates for a period of time... First, turn off the geared motor 2, then start the cylinder 2 702. The output end of the cylinder 2 702 extends and drives the transmission gear 1 707 and transmission gear 2 708 to mesh with the drive gear 706. Then, start the geared motor 2 again. At this time, the two reciprocating screws 709 rotate accordingly, causing the two pusher plates 710 to move vertically upward in the two liquid storage tanks 4. When the pusher plates 710 move, they push the additives, causing the additives to be discharged into the raw materials through the drain pipe 400. This achieves automatic feeding of various additives, with strong linkage and matching with the mixing degree of the raw materials, improving the accuracy of feeding and increasing applicability.

[0036] After mixing is complete, the geared motor 2 is turned off, and the material is discharged from the reactor. Then, cylinder 605 is started. After cylinder 605 operates, it pushes the slider 601 to move a certain distance in the chute 600. When the slider 601 moves, it drives the rotating rod 602, the anchor stirring rod 603, and several mixing blades 604 to rotate. At the same time, one end of the anchor stirring rod 603 is in contact with the inner wall of the reactor 1. Then, the geared motor 2 is started. At this time, the anchor stirring rod 603 can scrape off the material remaining on the inner wall of the reactor 1 when it rotates. After the cylinder 605 and the geared motor 2 are turned off, the material can fall off under the action of gravity. The purpose of the anchor stirring rod 603 can be adjusted by electric control. The anchor stirring rod not only reduces the probability of material remaining on the inner wall of the reactor 1, but also increases the mixing range and has strong applicability.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
