Technical Field
[0001] The utility model relates to the technical field of reaction kettles, in particular to a polymerization reaction defoaming agent feeding device. Background Art
[0002] A reactor is a device used for chemical reactions, synthesis reactions or other physical processes. It usually has a closed container structure and can react under controlled temperature, pressure and stirring conditions. Reactors are widely used in the chemical industry, pharmaceutical industry, food processing, petrochemical industry and other fields.
[0003] When the reactor is processing materials, it is necessary to add polymerization defoaming agent inside to dissipate the reaction effect of the materials. The amount of defoaming agent used will also affect the quality of the final product. The amount of traditional defoaming agent added is controlled by the staff themselves. If excessive addition occurs, the defoaming agent may have a negative impact on the polymerization reaction, such as reducing reaction efficiency, changing product properties or causing unnecessary cost waste. If a small amount of this phenomenon occurs, the bubbles may not be completely removed, affecting the appearance and performance of the product.
[0004] Therefore, in view of the above problems, we need to propose a polymerization reaction defoaming agent feeding device. Utility Model Content
[0005] The utility model aims to provide a polymerization reaction defoamer feeding device to solve the problems raised in the above background technology.

[0007] Preferably, the left side of the motor is fixedly connected to the adding shell, the output end of the motor passes through the inner cavity of the adding shell and is fixedly connected to a screw rod, the surface of the screw rod is threadedly connected to a threaded sleeve, and the surface of the threaded sleeve is fixedly connected to the piston plate.
[0008] Preferably, a retaining ring is sleeved on the surface of the motor, and the left side of the retaining ring is fixedly connected to the adding shell.
[0009] Preferably, a positioning ring is fixedly connected to the right side of the partition, and the surface of the positioning ring is fixedly connected to the inner wall of the adding shell.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] The utility model firstly connects the feed pipe with the adding hole on the top of the reactor. When the polymerization reaction defoamer needs to be added, firstly the output end of the motor drives the piston plate to move through the screw rod so that the threaded sleeve drives the piston plate to move. When the piston plate moves to the right, the second one-way valve will be opened by air pressure. At this time, the polymerization reaction defoamer inside the storage shell will be pumped into the inside of the adding shell. When the piston plate moves to the left, the air pressure will inject the polymerization reaction defoamer into the inside of the feed pipe through the first one-way valve. Since the left and right moving distance of the piston plate is limited, the amount of the polymerization reaction defoamer extracted each time will be limited, thereby achieving the effect of quantitative addition.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 As shown, a polymerization reaction defoaming agent feeding device comprises an adding shell 1, and also comprises: a feeding pipe 2 connected to the left side of the adding shell 1, the top of the adding shell 1 is connected to a feeding pipe 6, the top of the feeding pipe 6 is connected to a storage shell 3, the top of the storage shell 3 is connected to a connecting pipe 4, the inner cavity of the adding shell 1 is fixedly connected to a partition 9, the surface of the partition 9 is provided with an air outlet 11, the inner cavity of the adding shell 1 is provided with a piston plate 15, and the surface of the storage shell 3 is provided with a scale 7; an adding component 5 fixedly connected to the right side of the adding shell 1 for quantitatively adding the defoaming agent, and the adding component 5 comprises a motor 501.
[0023] refer to Figure 1 , Figure 2 and Figure 3 As shown, the left side of the motor 501 is fixedly connected to the adding shell 1, the output end of the motor 501 passes through the inner cavity of the adding shell 1 and is fixedly connected to the screw rod 502, the surface of the screw rod 502 is threadedly connected to the threaded sleeve 503, the surface of the threaded sleeve 503 is fixedly connected to the piston plate 15, the surface of the motor 501 is sleeved with a retaining ring 504, and the left side of the retaining ring 504 is fixedly connected to the adding shell 1.
[0024] It should be noted that: first, the output end of the motor 501 drives the threaded sleeve 503 to drive the piston plate 15 to move through the screw rod 502. When the piston plate 15 moves to the right, the second one-way valve 12 will be opened by air pressure. At this time, the polymerization reaction defoaming agent inside the storage shell 3 will be pumped into the inside of the adding shell 1. When the piston plate 15 moves to the left, the air pressure will inject the polymerization reaction defoaming agent into the inside of the feed pipe 2 through the first one-way valve 8. Since the distance that the piston plate 15 moves left and right is limited, the amount of polymerization reaction defoaming agent extracted each time will be limited, thereby achieving the effect of quantitative addition. By setting the retaining ring 504, the motor 501 is positioned and protected.
[0025] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a positioning ring 10 is fixedly connected to the right side of the partition 9, and the surface of the positioning ring 10 is fixedly connected to the inner wall of the adding shell 1. The inner cavity of the feed pipe 2 is provided with a threaded ring 13, and the material of the threaded ring 13 is stainless steel. The threaded ring 13 and the feed pipe 2 are integrally formed, and the inner cavity of the adding shell 1 is provided with a first one-way valve 8, and the inner cavity of the connecting pipe 4 is provided with a second one-way valve 12. The bottom of the adding shell 1 is fixedly connected with a support frame 14, and the material of the support frame 14 is stainless steel. The inner cavity of the piston plate 15 is movably connected with a slide rod 16, and the two sides of the slide rod 16 are respectively fixedly connected to the partition 9 and the adding shell 1.
[0026] It should be noted that: by setting the positioning ring 10, the partition 9 is positioned, by setting the threaded ring 13, a vortex is formed when the polymerization reaction defoaming agent is discharged, and the polymerization reaction defoaming agent is better integrated with the material. By setting the first one-way valve 8 and the second one-way valve 12, the polymerization reaction defoaming agent can be added quantitatively. By setting the support frame 14, the adding shell 1 is positioned, and by setting the sliding rod 16, the piston plate 15 is limited.
[0027] Working principle: First, the staff puts the polymerization reaction defoamer into the storage shell 3 for storage, and then connects the feed pipe 2 with the adding hole on the top of the reactor. When the polymerization reaction defoamer needs to be added to the reactor, the motor 501 is turned on first, and the output end of the motor 501 drives the threaded sleeve 503 to drive the piston plate 15 to move through the screw rod 502. When the piston plate 15 moves to the right, the second one-way valve 12 will be opened by air pressure. At this time, the polymerization reaction defoamer inside the storage shell 3 will be pumped into the adding shell 1. When the piston plate 15 moves to the left, the air pressure will inject the polymerization reaction defoamer into the feed pipe 2 through the first one-way valve 8. Since the distance that the piston plate 15 moves left and right is limited, the amount of polymerization reaction defoamer extracted each time will be limited, thereby achieving the effect of quantitative addition.
