Description

Technical Field

[0001] This utility model relates to the field of air-entraining agent production technology, specifically to an injection device for air-entraining agent raw materials. Background Technology

[0002] A gas-entraining agent is a substance that creates pores in a target material. It can be broadly classified into three categories: chemical gas-entraining agents, physical gas-entraining agents, and surfactants. Chemical gas-entraining agents are compounds that, upon heating and decomposition, release gases such as carbon dioxide and nitrogen, forming fine pores within the polymer composition. Physical gas-entraining agents are formed when the foam pores are created through a change in the physical state of a substance, such as the expansion of compressed gas, the evaporation of liquid, or the dissolution of solid. All gas-entraining agents possess high surface activity, effectively reducing the surface tension of liquids and arranging themselves in a double electron layer on the liquid film surface to surround air, forming bubbles. These individual bubbles then combine to form foam. The equipment used to manufacture gas-entraining agents is inseparable from reaction vessels.

[0003] However, since the raw materials for manufacturing the air-entraining agent are currently liquid, they need to be manually poured into the reactor. This is not only very troublesome, but also increases labor costs. Furthermore, the reactor generally needs to be heated when mixing the raw materials, and the poured-in raw materials, since they have not been preheated, will affect the reaction effect and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an injection device for air-entraining agent raw materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection device for air-entraining agent raw materials, comprising:

[0006] Reactor;

[0007] The raw material injection mechanism includes multiple raw material injection mechanisms, each including an infusion pipeline and a mixing pipeline. The mixing pipeline is fixedly installed at one end of the infusion pipeline. The infusion pipeline includes an outer sleeve and an inner sleeve. The inner sleeve is fixedly installed inside the outer sleeve, and a heating element is wound around the outer wall surface of the inner sleeve.

[0008] PLC controller;

[0009] The PLC controller is fixedly installed on one side of the outer wall of the reactor.

[0010] The PLC controller is electrically connected to the heating element.

[0011] Preferably, the mixing pipeline includes an outer ring pipe and a support rod. The bottom surface of the outer ring pipe has a liquid outlet hole, and there are multiple liquid outlet holes. The inner wall surface of the outer ring pipe is fixedly connected to a liquid guiding branch pipe, and there are multiple liquid guiding branches. The end of the liquid guiding branch pipe away from the outer ring pipe is fixedly connected to the surface of the support rod.

[0012] Preferably, the raw material injection mechanism further includes a connecting conduit and a water pump, one end of the connecting conduit being fixedly connected to the output end of the water pump, and the other end of the connecting conduit being fixedly connected to the inner sleeve of the infusion pipeline;

[0013] The PLC controller is electrically connected to the water pump.

[0014] Preferably, the inner wall surface of the outer sleeve is adhered with a heat insulation layer.

[0015] Preferably, the end of the infusion tubing away from the connecting conduit is fixedly connected to the surface of the infusion branch tube, and the inner sleeve and the infusion branch tube are interconnected.

[0016] Preferably, the mixing pipeline is fixedly installed at the top of the inside of the reactor by a support rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model has a simple structure, is easy and quick to operate, has low manufacturing cost and safe and reliable performance. It replaces the shortcomings of traditional manual addition of raw materials, which can not only effectively improve work efficiency, but also greatly reduce the labor intensity of workers, and has very good practicality.

[0019] 2. This utility model, through the installed infusion pipeline, allows the water pump to inject liquid raw materials into the connecting conduit, and then into the inner sleeve. Since the temperature of the heating element is preset in the PLC controller, the heat generated by the heating element will be conducted to the raw materials in the inner sleeve, thus heating the raw materials entering the inner sleeve and achieving preheating treatment of the raw materials. This can improve the reaction effect of the raw materials and greatly improve work efficiency.

[0020] 3. In this utility model, the preheated liquid enters the liquid guiding branch pipe through the installed mixing pipeline. Multiple raw materials can simultaneously enter multiple liquid guiding branch pipes from multiple pipelines, and then flow into the outer ring pipe for mixing. Finally, the liquid flows into the reaction vessel from the outlet hole. Since multiple water streams flow into the outer ring pipe at the same time, the collision between the multiple water streams will improve the mixing effect of the raw materials, thereby improving the reaction effect of the raw materials and greatly shortening the stirring time.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: an injection device for gas-entraining agent raw materials, including: a reaction vessel 10, a raw material injection mechanism 20 and a PLC controller 30.

[0029] The raw material injection mechanism 20 is provided in multiple ways. The raw material injection mechanism 20 includes an infusion pipeline 21 and a mixing pipeline 24. The mixing pipeline 24 is fixedly installed at one end of the infusion pipeline 21. The infusion pipeline 21 includes an outer sleeve 211 and an inner sleeve 214. The inner sleeve 214 is fixedly installed inside the outer sleeve 211. A heating element 213 is wound around the outer wall surface of the inner sleeve 214.

[0030] Furthermore, the outer sleeve 211 is made of PVC material.

[0031] Furthermore, the inner sleeve 214 can be made of aluminum alloy or aluminum material.

[0032] Furthermore, the heating element 213 is specifically a heating band.

[0033] Furthermore, the water pump 23 can inject liquid raw materials into the connecting conduit 22 and then into the inner sleeve 214. Since the temperature of the heating element 213 is set in advance in the PLC controller 30, the heat generated by the heating element 213 will be conducted to the raw materials in the inner sleeve 2214, thus heating the raw materials entering the inner sleeve 214. This can achieve preheating treatment of the raw materials, thereby improving the reaction effect of the raw materials and greatly improving work efficiency.

[0034] The PLC controller 30 is fixedly installed on one side of the outer wall of the reactor 10.

[0035] The PLC controller 30 is electrically connected to the heating element 213.

[0036] Furthermore, the temperature of the heating element 213 can be preset in the PLC controller 30, and the temperature of the heating element 213 in different infusion lines 21 can also be set according to the different raw materials injected, so as to avoid damage to the raw materials due to excessive temperature.

[0037] The mixing pipeline 24 includes an outer ring pipe 241 and a support rod 243. The bottom surface of the outer ring pipe 241 is provided with a liquid outlet hole 244, and there are multiple liquid outlet holes 244. The inner wall surface of the outer ring pipe 241 is fixedly connected with a liquid guiding branch pipe 242, and there are multiple liquid guiding branch pipes 242. The end of the liquid guiding branch pipe 242 away from the outer ring pipe 241 is fixedly connected to the surface of the support rod 243.

[0038] Furthermore, the preheated liquid enters the liquid guiding branch pipe 242 through the liquid delivery line 21. Multiple raw materials can simultaneously enter multiple liquid guiding branch pipes 242 from multiple liquid delivery lines 21, and then flow into the outer ring pipe 241 for mixing. Finally, it flows into the reaction vessel 10 from the liquid outlet 244. Since multiple water streams flow into the outer ring pipe 241 at the same time, the collision between the multiple water streams will improve the mixing effect of the raw materials, thereby improving the reaction effect of the raw materials and greatly shortening the stirring time.

[0039] The raw material injection mechanism 20 also includes a connecting conduit 22 and a water pump 23. One end of the connecting conduit 22 is fixedly connected to the output end of the water pump 23, and the other end of the connecting conduit 22 is fixedly connected to the inner sleeve 214 of the infusion pipeline 21.

[0040] Furthermore, the input end of the water pump 23 is connected to the raw material, and the operation of the water pump 23 can inject the raw material into the connecting conduit 22, providing power output to the raw material.

[0041] The PLC controller 30 is electrically connected to the water pump 23.

[0042] The inner wall surface of the outer sleeve 211 is bonded with a heat insulation layer 212.

[0043] Furthermore, the heat insulation layer 212 is specifically made of glass fiber.

[0044] Furthermore, the insulation layer 212 has a good heat insulation effect, preventing the temperature generated by the heating element 213 from being transmitted to the outer sleeve 211, thus preventing burns to the human body.

[0045] The end of the infusion line 21 away from the connecting conduit 22 is fixedly connected to the surface of the liquid guiding branch 242, and the inner sleeve 214 is interconnected with the liquid guiding branch 242.

[0046] Furthermore, the raw materials entering the inner sleeve 214 will enter the liquid guiding branch 242.

[0047] The mixing pipeline 24 is fixedly installed at the top of the inside of the reactor 10 by a support rod 243, and the liquid outlet 244 is set downward.

[0048] Furthermore, the connection stability of the hybrid pipeline 24 is improved.

[0049] Working principle: During use, the water pump 23 can inject liquid raw materials into the connecting conduit 22, and then into the inner sleeve 214. Since the temperature of the heating element 213 is set in advance in the PLC controller 30, the heat generated by the heating element 213 will be conducted to the raw materials in the inner sleeve 2214, thus heating the raw materials entering the inner sleeve 214. The preheated liquid will enter the liquid guiding branch pipe 242 through the liquid delivery line 21. Multiple raw materials can enter multiple liquid guiding branch pipes 242 from multiple liquid delivery lines 21 at the same time, and then flow into the outer ring pipe 241 for mixing, and finally flow into the reaction vessel 10 from the liquid outlet 244.
