[0003] The main components of defoaming agents include active ingredients, emulsifiers, carriers and emulsifying aids. The active ingredient is the most important core part, which plays the role of breaking bubbles and reducing surface tension; the emulsifier disperses the active ingredient into small particles so that it can be better dispersed into oil or water, achieving a better defoaming effect; the carrier accounts for a large proportion of the defoaming agent, and its surface tension is not high. It mainly plays the role of a supporting medium, which is beneficial to the anti-foaming and defoaming effects and can reduce costs; the emulsifying aid makes the emulsification effect better.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0032] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, a defoaming agent liquid pump includes a pump body 1 and a conveying mechanism 2. The pump body 1 is made of 304 stainless steel with a thickness of not less than 5 mm. By limiting the material and size of the pump body 1, the corrosion resistance and strength of the pump body 1 can be effectively improved, and the service life of the device can be extended. The conveying mechanism 2 includes a motor 201 fixedly connected to the top of the pump body 1, and a coupling 202 is installed at the output shaft end of the motor 201. The output end of the coupling 202 is fixedly connected to a rotor 203. The inner wall of the pump body 1 is fixedly connected to a stator 204. The rotor 203 is made of high-strength engineering plastic with a smooth surface to improve its wear resistance. The stator 204 is made of high-performance rubber material with an inner diameter matching that of the rotor 203. By limiting the position and material of the rotor 203 and the stator 204, it can be ensured that the rotor 203 and the stator 204 In order to improve the sealing effect and the delivery effect of the defoaming agent, the sides of the pump body 1 are respectively equipped with a liquid inlet 205 and a liquid outlet 206, and the liquid outlet 206 is located above the liquid inlet 205. Both the liquid inlet 205 and the liquid outlet 206 are made of carbon steel. By limiting the position and material of the liquid inlet 205 and the liquid outlet 206, the delivery of the defoaming agent can be facilitated, and the delivery of the defoaming agent can be smoother. A detachable filter 207 is installed at one end of the liquid inlet 205, and a stainless steel filter mesh 208 is fixedly connected to the inner wall of the filter 207. The mesh diameter of the stainless steel filter mesh 208 does not exceed 0.5 mm, and the filtration area is not less than 0.1 m². The filter 207 and the stainless steel filter mesh 208 are located at the front end of the liquid inlet 205, which can improve the filtration effect, remove solid particles in the defoaming agent, and prevent clogging.
[0033] It should be noted that the rotor 203 is a multi-blade design and is installed inside the pump body 1. It can rotate at high speed when driven by the motor 201, and the stator 204 is fixed to the inner wall of the pump body 1 and can form a sealed chamber with the rotor 203. The sealed chamber formed between the rotor 203 and the stator 204 changes continuously with the rotation of the rotor 203, thereby generating thrust, pushing the defoaming agent liquid entering the liquid inlet 205 to the liquid outlet 206 for discharge.
[0034] See also Figure 1 、 Figure 2 and Figure 4Two sets of cooling mechanisms 3 are fixedly connected to the outer surface of the pump body 1. The cooling mechanism 3 includes a fan 301 installed on the upper surface of the pump body 1. An air outlet cover 302 and a heat sink 303 are fixedly connected to the outer surface of the pump body 1. By arranging the mutual cooperation between the fan 301, the air outlet cover 302 and the heat sink 303, the working conditions of the device can be improved, especially in a high temperature environment. The air outlet cover 302 is connected to the fan 301 through a ventilation pipe. The air outlet cover 302 is located above the heat sink 303. Through the above-mentioned connection method, the wind generated by the fan 301 can be transported to the surrounding of the heat sink 303 through the air outlet cover 302, thereby accelerating the volatilization of heat on the surface of the pump body 1.
[0035] It should be noted that the heat sink 303 should be made of a material with good thermal conductivity, such as aluminum or copper. The heat sink 303 can increase the heat dissipation surface area and accelerate heat dissipation by natural convection or forced air flow.
[0036] See also Figure 1 、 Figure 2 and Figure 3 A frequency converter 4 is installed on the upper surface of the pump body 1, and the motor 201 is electrically connected to the frequency converter 4. A sensor assembly 5 is installed on the inner bottom wall of the pump body 1. The sensor assembly 5 consists of a temperature sensor and a pressure sensor, which can conveniently know the pressure and temperature inside the device. The sensor assembly 5 and the fan 301 are both electrically connected to the frequency converter 4. By limiting the above relationship, the speed of the motor 201 can be conveniently adjusted according to the working conditions of the device to ensure stable operation of the device.
[0037] It should be noted that the frequency converter 4 is an existing device, and its internal structure and working principle are not described in detail here. However, it should be understood that the frequency converter 4 applies frequency conversion technology and microelectronics technology to control the power control device of the AC motor by changing the working power frequency of the motor 201. Preferably, the model of the frequency converter 4 can be ABB ACS880.
[0038] In this embodiment, the conveying mechanism 2 is set up to improve the efficiency and reliability of the device body in conveying the defoaming agent. Through the cooperation between the rotor 203 and the stator 204, the defoaming agent liquid with high viscosity and containing solid particles can be efficiently conveyed, thereby optimizing the scope of application of the device. The cooling mechanism 3 is set up to effectively avoid the overheating problem of the device body, thereby improving the overall performance and safety of the pump. The filter 207 and the stainless steel filter mesh 208 are set up to remove the solid particles in the defoaming agent, thereby reducing blockage and maintenance costs and extending the service life.
[0039] The working principle of the above embodiment is as follows: after the motor 201 is started, the coupling 202 is driven to rotate, and the rotation of the coupling 202 can make the rotor 203 rotate at a high speed, so that the sealed chamber formed between the rotor 203 and the stator 204 changes continuously with the rotation of the rotor 203, thereby generating thrust, so that the defoaming agent entering the liquid inlet 205 can be pushed to the liquid outlet 206 for discharge, and the defoaming agent can be filtered through the stainless steel filter 208 before entering the liquid inlet 205, which can filter out solid particles in the defoaming agent and reduce blockage inside the device. At the same time, the working status of the pump can be monitored in real time through the sensor component 5, and the speed of the motor 201 can be adjusted through the inverter 4 as needed. At the same time, when the sensor component 5 detects that the temperature is too high, the two fans 301 can be driven to work through the inverter 4. When the fans 301 are working, they can deliver wind toward the air outlet cover 302. The generated wind will be delivered to the surrounding of the heat sink 303 through the air outlet cover 302, and then it can accelerate the volatilization of the heat on the surface of the heat sink 303, thereby achieving the effect of reducing the temperature of the pump body 1 and extending the service life of the device.
