Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a methylal quantitative feeding device. Background Art

[0002] When methanol and hexahydroxymethylmelamine are subjected to etherification reaction, methylal is added (methylal refers to the compound generated by the dehydration of formaldehyde and methanol, which can "absorb" the water generated in the etherification reaction and has no other effects on the etherification reaction itself). Through the balanced reaction between the added methylal and methanol, formaldehyde and water, the free water generated in the etherification reaction system is reduced, so that the etherification reaction proceeds in a direction that is favorable to the formation of etherification products. In addition, the reduction of water content can also reduce the condensation polymerization between molecules.

[0003] In the current prior art, during the equilibrium reaction between methylal and methanol, formaldehyde and water, methylal needs to be added in batches according to the reaction. However, the existing dropper addition method requires the control of the dropper suction before adding the material, which has low operating efficiency and affects the overall experimental process.

[0004] Therefore, a methylal quantitative feeding device is proposed in view of the above problems. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that methylal needs to be added in batches according to the reaction during the equilibrium reaction between methylal and methanol, formaldehyde and water, while the existing dropper addition method has low operating efficiency and affects the overall experimental process, a methylal quantitative feeding device is proposed.

[0013] Beneficial effects of the utility model:

The methylal raw material is stored in the material box 1, the material box 1, the quantitative box 2 and the feeding port 3 are connected to each other, and the feeding port 3 is connected to the reactor of the experimental device through a pipeline. The opening and closing of the valve 31 controls the connection state, and controls the raw material filling before feeding. The whole device and the pipeline connected to the reactor are filled, so that when raw materials need to be added, the quantitative component 4 can be moved to directly carry out the feeding process. The quantitative component 4 is installed in the quantitative box 2 through the straight slot opening 21 and the baffle slot 22. The amount of medicine added to the reactor can be controlled by the lifting and lowering control device of the quantitative component 4. Before adding materials, the rotating shaft 431 is rotated to make the outer part of the circular rubber plate 43 and the rubber interlayer 411 misaligned with each other. At this time, the raw materials can pass through the gap between the circular rubber plate 43 and the rubber interlayer 411. At this time, the quantitative frame 41 and the rotating shaft 431 are moved to the medicine adding position, and then the rotating shaft 43 is rotated. 1. Reset the circular rubber plate 43, and then move the quantitative component 4 to the lower limit to achieve the addition of raw materials. The quantitative direct addition method omits the process of adding materials by suction through a dropper, thereby improving the operating efficiency during the addition process and reducing the impact of the addition process on the experimental process. The lifting sliders 42 on both sides of the quantitative frame 41 are slidably installed between the straight groove opening 21, and the opening baffle 421 can block the straight groove opening 21 during the lifting process to prevent liquid leakage. The opening baffle 421 and the baffle groove 22 fit each other to prevent the opening baffle 421 from being blocked during the lifting movement of the quantitative component 4;

[0026] like Figure 3 , Figure 4 and Figure 5As shown, the two lifting sliders 42 are fixedly connected to the outside with positioning plates 44, and the side walls of the two positioning plates 44 are provided with limiting grooves 441, and the two ends of the rotating shaft 431 are provided with rotating grooves 432. The limiting clamping rod 45 is slidably installed between the inner walls of the rotating grooves 432, and a handle 451 is fixedly connected between one ends of the two limiting clamping rods 45. The outer walls of the other ends of the two limiting clamping rods 45 can be respectively engaged with the two limiting grooves 441. When controlling the overall rotation of the circular rubber plate 43 and the rotating shaft 431, it is necessary to pull the handle 451 to disengage the limiting clamping rod 45 from the limiting groove 441 of the positioning plate 44, and then control the limiting clamping rod 45, the handle 451, the circular rubber plate 43 and the rotating shaft 431 to rotate as a whole, so as to achieve the misalignment between the circular rubber plate 43 and the rubber interlayer 411.

[0027] like Figure 3 and Figure 5 As shown, a limiting arc block 452 is fixedly connected between the outer walls of the two limiting rods 45, and the limiting arc block 452 is close to the end where the limiting groove 441 is located. The limiting arc block 452 can prevent the limiting rod 45 from being separated from the rotating groove 432 during the process of pulling the handle 451;

[0028] like Figure 1 and Figure 4 As shown, a scale plate 5 is provided on the side wall of the quantitative box 2, and arrows 442 are symmetrically fixed to the side walls of the two positioning plates 44, and one end of the two arrows 442 is aligned with the edges of both sides of the scale plate 5, and the scale plate 5 and the arrows 442 are aligned to read the amount of material added;

[0029] Working principle: the methylal raw material is stored in the material box 1, the material box 1, the quantitative box 2 and the feeding port 3 are connected to each other, the feeding port 3 is connected to the reactor of the experimental device through a pipeline, the opening and closing of the valve 31 controls the connection state, and the raw material is controlled to fill the entire device and the pipeline connected to the reactor before feeding, so that when the raw material needs to be added, the mobile quantitative component 4 can directly carry out the feeding process, and the quantitative component 4 is installed in the quantitative box 2 through the straight groove opening 21 and the baffle groove 22, and the dosage of the quantitative component 4 can be controlled by lifting and lowering the device to the reactor. The scale plate 5 and the arrow 442 can read the dosage afterwards, and the rotating shaft 431 is rotated before feeding to make the outer part of the circular rubber plate 43 and the rubber interlayer 411 mutually misaligned. At this time, the raw material can pass through the gap between the circular rubber plate 43 and the rubber interlayer 411. At this time, the mobile quantitative component 4 The measuring frame 41 and the rotating shaft 431 are moved to the dosage adding position, and then the rotating shaft 431 is rotated to reset the circular rubber plate 43. Then, the quantitative component 4 is moved to the lower limit to realize the addition of raw materials, wherein the lifting sliders 42 on both sides of the quantitative frame 41 are slidably installed between the straight groove openings 21, and the opening baffle 421 can block the straight groove openings 21 during the lifting process to prevent liquid leakage. When controlling the overall rotation of the circular rubber plate 43 and the rotating shaft 431, it is necessary to pull the handle 451 to disengage the limit card rod 45 from the upper limit groove 441 on the positioning plate 44.
