Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical industry technology, and more specifically, it relates to a catalyst quantitative addition device. Background Technology
[0002] The production of expanded microsphere foaming agent requires processes such as emulsification, polymerization, and drying. When the expanded microsphere foaming agent undergoes polymerization, the foaming agent raw material needs to be placed inside the reactor, and then the catalyst is added to the reactor through a quantitative addition device to carry out the reaction and polymerization, so that the expanded microsphere foaming agent can be produced.
[0003] According to CN202322093414.0, this utility model discloses a device for quantitatively adding a mixed catalyst, including a storage chamber, a quantitative feed chamber, and a discharge port. The storage chamber, quantitative feed chamber, and discharge port are divided into three parts: upper, middle, and lower. The storage chamber is at the top, the quantitative feed chamber is fixedly installed below the storage chamber, and the discharge port is fixedly installed below the quantitative feed chamber. The quantitative feed chamber is located in the middle of the storage chamber and the discharge port. A storage chamber cover is movably connected to the top of the storage chamber, and a storage chamber switch button is fixedly connected to one side of the storage chamber cover. This utility model utilizes the coordinated use of the quantitative feed chamber, the discharge port, the funnel-shaped groove, the groove baffle, the control button, the quantitative pipe, and the discharge port to introduce the catalyst into the storage chamber. The required amount is set in the quantitative feed chamber, and after entering the feed chamber, the weighed mixed catalyst is discharged from the discharge port.
[0004] Based on the above, existing quantitative addition devices are generally installed at the feed inlet of the reactor. The catalyst is directly controlled to enter the reactor through the quantitative component. Since the catalyst is in powder or granular form, it is easy to agglomerate into lumps when stored. After the catalyst lumps directly enter the reactor, they need to be dispersed in the reactor before participating in the polymerization reaction, which will affect the polymerization efficiency of the expanded microsphere foaming agent. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a catalyst quantitative addition device. This addresses the issue that existing quantitative addition devices are generally installed at the feed inlet of a reactor, directly controlling the entry of the catalyst into the reactor through a quantitative component. Since the catalyst is in powder or granular form, it is prone to agglomeration during storage. When the catalyst clumps directly enter the reactor, they need to be dispersed inside the reactor before participating in the polymerization reaction, which affects the polymerization efficiency of the expanding microsphere foaming agent.
[0006] The purpose and effect of this utility model's catalyst quantitative addition device are achieved by the following specific technical means:
[0007] A catalyst metering device includes an addition storage tank, an addition body, a body edge, a power rotating block, a feed strainer, a feed connecting block, an addition installation mechanism, and an addition crushing mechanism.

The feed connecting block is fixedly connected to the inner end face of the power rotating block and slides on the upper side of the feed strainer. The feed connecting block has a rectangular structure. The addition installation mechanism is disposed on the upper side of the addition storage tank. The addition crushing mechanism is disposed inside the addition body.
[0008] Furthermore, the installation mechanism includes: mounting screw holes and mounting bolts; multiple sets of mounting screw holes are provided, which are respectively opened on the main body edge and the upper end face of the storage tank; multiple sets of mounting bolts are provided, which are respectively threaded into the multiple sets of mounting screw holes.
[0009] Furthermore, the adding and crushing mechanism includes a power motor and a power shaft; the power motor is fixedly connected to the left side inside the adding body; the power shaft is rotatably connected to the left side inside the adding body, and the power motor shaft and the power shaft are coaxially fixedly connected.
[0010] Furthermore, the adding and crushing mechanism also includes a power gear and a power gear ring; the power gear is coaxially and fixedly connected to the power shaft, and the power gear rotates inside the left side of the adding body; the power gear ring is coaxially and fixedly connected to the lower side of the outer end face of the power rotating block, and the power gear and the power gear ring mesh together to form a gear and gear ring transmission mechanism.
[0011] Furthermore, the crushing mechanism also includes a feeding ramp; the feeding ramp is located on the upper end face of the feeding connecting block and has a semi-circular structure.
[0012] Furthermore, the feeding and crushing mechanism also includes: a feeding block and a feeding spring; the feeding block is slidably connected to the lower side inside the feeding connecting block, and slides on the upper surface of the feeding screen; the feeding block is a rectangular plate structure of polytetrafluoroethylene; multiple sets of feeding springs are provided, and the multiple sets of feeding springs are respectively fixedly connected inside the feeding connecting block and respectively fixedly connected to the feeding block.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model employs an addition and installation mechanism, which allows the addition body to be installed on the upper surface of the addition storage tank via mounting screw holes and bolts. The catalyst is quantitatively added into the addition storage tank through the addition body, making it convenient for staff to install and disassemble the addition body and facilitating the subsequent maintenance of the quantitative addition device.
[0015] This invention employs an addition and crushing mechanism. When the catalyst is added to the addition storage tank through the addition body, the catalyst reaches the feed screen position, where the feed briquetting block crushes the agglomerated catalyst, allowing it to enter the addition storage tank in powder or granular form. The catalyst then enters the addition storage tank for polymerization, avoiding the need for dispersion before polymerization of agglomerated catalyst, thus ensuring the polymerization efficiency of the expanded microsphere foaming agent.

[0028] The addition and installation mechanism includes: mounting screw holes 4 and mounting bolts 5; multiple sets of mounting screw holes 4 are provided, which are respectively opened on the main body edge 3 and the upper end face of the addition storage tank 1; multiple sets of mounting bolts 5 are provided, which are respectively threaded into the multiple sets of mounting screw holes 4. During use, when the addition body 2 is installed on the upper end face of the addition storage tank 1, the movement of the addition body 2 drives the movement of the main body edge 3, which in turn drives the movement of the mounting screw holes 4 on the main body edge 3. The mounting screw holes 4 on the main body edge 3 and the mounting screw holes 4 on the addition storage tank 1 are aligned, and the mounting bolts 5 are installed inside the mounting screw holes 4, thereby fixing the addition body 2 to the upper end face of the addition storage tank 1. The catalyst enters the addition storage tank 1 through the addition body 2 for quantitative addition.
[0029] The specific usage and function of this first embodiment are as follows:
[0030] During use, when the additive body 2 is installed on the upper surface of the additive storage tank 1, the movement of the additive body 2 causes the main body edge 3 to move, and the movement of the main body edge 3 causes the mounting screw holes 4 on the main body edge 3 to move. The mounting screw holes 4 on the main body edge 3 are aligned with the mounting screw holes 4 on the additive storage tank 1, and the mounting bolts 5 are installed inside the mounting screw holes 4, thereby fixing the additive body 2 to the upper surface of the additive storage tank 1. The catalyst enters the additive storage tank 1 through the additive body 2 for quantitative addition, realizing the installation and removal of the additive body 2 on the additive storage tank 1.
[0031] Example 2:
[0032] Based on Example 1, as shown in the appendix Figure 4 To be continued Figure 6 As shown:
[0033] This utility model provides a catalyst quantitative addition device, which also includes an addition and pulverizing mechanism. The addition and pulverizing mechanism includes a power motor 6 and a power shaft 7. The power motor 6 is fixedly connected to the left side inside the addition body 2. The power shaft 7 is rotatably connected to the left side inside the addition body 2. The shaft of the power motor 6 and the power shaft 7 are coaxially fixedly connected. During use, the rotation of the shaft of the power motor 6 drives the rotation of the power shaft 7.
[0034] The crushing mechanism also includes a power gear 701 and a power gear ring 9. The power gear 701 is coaxially fixedly connected to the power shaft 7 and rotates inside the left side of the adding body 2. The power gear ring 9 is coaxially fixedly connected to the lower side of the outer end face of the power rotating block 8. The power gear 701 and the power gear ring 9 mesh together to form a gear and gear ring transmission mechanism. During use, the rotation of the power shaft 7 drives the power gear 701 to rotate, the rotation of the power gear 701 drives the meshing power gear ring 9 to rotate, the rotation of the power gear ring 9 drives the power rotating block 8 to rotate, and the rotation of the power rotating block 8 drives the feeding connecting block 11 to rotate.
[0035] The addition of the crushing mechanism also includes a feeding inclined surface 1101. The feeding inclined surface 1101 is located on the upper end face of the feeding connecting block 11. The feeding inclined surface 1101 has a semi-circular structure. During use, when the catalyst falls onto the upper side of the feeding connecting block 11 through the semi-circular feeding inclined surface 1101, the catalyst falls onto the feeding screen 10 through the feeding inclined surface 1101.
[0036] The crushing mechanism also includes a feeding block 12 and a feeding spring 1201. The feeding block 12 is slidably connected to the lower side inside the feeding connecting block 11 and slides on the upper surface of the feeding screen 10. The feeding block 12 is a rectangular plate structure of polytetrafluoroethylene. Multiple sets of feeding springs 1201 are provided. The multiple sets of feeding springs 1201 are fixedly connected inside the feeding connecting block 11 and fixedly connected to the feeding block 12. During use, the spring force of the feeding spring 1201 drives the feeding block 12 to slide downward. The feeding block 12 slides downward and fits against the upper surface of the feeding screen 10. When the feeding connecting block 11 drives the feeding block 12 to rotate, the feeding block 12 crushes the catalyst, causing the catalyst to be crushed.
[0037] The specific usage and function of this second embodiment are as follows:
[0038] During use, the rotation of the shaft of the power motor 6 drives the rotation of the power shaft 7, which in turn drives the rotation of the power gear 701. The rotation of the power gear 701 drives the rotation of the meshing power gear ring 9, which in turn drives the rotation of the power block 8. The rotation of the power block 8 drives the rotation of the feed connecting block 11. As the catalyst falls onto the upper side of the feed connecting block 11 through the semi-circular feed ramp 1101, it falls onto the feed strainer 10. The spring force of the feed spring 1201 drives the feed pressing block 12 to slide downward. The feed pressing block 12 slides downward and adheres to the upper end face of the feed strainer 10. When the feed connecting block 11 drives the feed pressing block 12 to rotate, the feed pressing block 12 crushes the catalyst, making the catalyst pulverized. This ensures that the catalyst enters the addition storage tank 1 in a pulverized state, facilitating rapid polymerization of the catalyst inside the addition storage tank 1.
