Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agent production equipment, in particular to a cooling device for an atomizer motor in the production of naphthalene-based water reducing agent. Background Art

[0002] Naphthalene water reducer is the most widely used high-efficiency water reducer in my country (accounting for more than 70% of the water reducer usage). It is characterized by high water reduction rate, no air entrainment, little effect on setting time, relatively good adaptability to cement, and can be used in combination with various other admixtures. It is also relatively cheap. At present, in the production of naphthalene water reducer, atomization and drying of the product is a relatively important process. The atomizer motor is the core component of the centrifugal drying tower, which is used to atomize the liquid into tiny droplets for drying. However, during long-term operation, the atomizer motor is prone to overheating, affecting its performance and service life. If it causes frequent downtime, it will seriously affect the continuity of production, thereby affecting the output and quality of the product. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a cooling device for an atomizer motor in the production of naphthalene-based water reducing agent, which utilizes the gas discharged after tail gas treatment to cool the atomizer motor, thereby ensuring the normal operation of the atomizer motor and thus ensuring the continuity of production.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A cooling device for an atomizer motor in the production of a naphthalene-based water-reducing agent comprises a motor, an atomizer is arranged at the lower part of the motor, a temperature sensor is arranged on the side wall of one side of the motor, and an air outlet of a cooling pipeline is arranged at the upper part of the motor; the other end of the cooling pipeline is connected to an induced draft fan, and the other end of the induced draft fan is connected to an exhaust tower of an exhaust gas treatment system through a pipeline; the temperature sensor and the induced draft fan are both electrically connected to an automatic control system.

[0006] Preferably, the temperature sensor is a remote temperature sensor. The temperature sensor is a WZPK110 temperature transmitter produced by Jiangsu Jie Chuang Technology Co., Ltd.

[0007] Preferably, the air outlet is a trumpet-shaped air outlet, and the port diameter of the air outlet is larger than the diameter of the motor.

[0008] Preferably, an activated carbon layer is arranged at the lower part of the exhaust tower, and the air inlet of the air duct of the induced draft fan is arranged at the upper part of the activated carbon layer. The activated carbon can filter out impurities such as particles in the exhaust gas to ensure that the wind will not cause damage to the motor.

[0009] Preferably, the exhaust gas treatment system comprises a condenser, an alkali liquid spray tower, a formaldehyde removal adsorption spray tower and an emptying tower. After the exhaust gas is treated by the condenser, the alkali liquid spray tower and the formaldehyde removal adsorption spray tower, the temperature of the exhaust gas is the same as the temperature of the formaldehyde removal adsorption spray liquid in the natural environment, which is much lower than the motor temperature during operation and also lower than the natural temperature in the temperate summer.

[0010] Preferably, the automatic control system is a PLC automatic control system, and a temperature threshold is provided in the PLC automatic control system. When the detected temperature is lower than the low temperature threshold, the induced draft fan is turned off; when the detected temperature is higher than the high temperature threshold, the induced draft fan is started.

[0011] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The utility model reuses the cold gas discharged after being treated by the tail gas treatment system to cool the atomizer motor, which can effectively save energy;

[0013] 2. The automatic control system of the utility model controls the start and shut down of the induced draft fan, which can save energy to the maximum extent while ensuring the whole operation of the motor;

[0014] In short, the utility model has a simple structure and is easy to implement. It can effectively solve the problem of overheating of the atomizer motor of the centrifugal drying tower, improve the performance and service life of the atomizer motor, and thus ensure production efficiency and product quality.

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiment 1

[0019] like Figure 1As shown, a cooling device for an atomizer motor in the production of a naphthalene-based water-reducing agent comprises a motor 1, an atomizer 2 is arranged at the lower part of the motor 1, a temperature sensor 3 is arranged on the side wall of one side of the motor 1, an air outlet (not marked) of a cooling pipe 4 is arranged at the upper part of the motor 1, the other end of the cooling pipe 4 is connected to an induced draft fan 5, the other end of the induced draft fan 5 is connected to an exhaust tower 6 of an exhaust gas treatment system (not marked) through a pipeline (not marked), an activated carbon layer 7 is arranged at the lower part of the exhaust tower 6, and an air outlet (not marked) of the induced draft pipe (not marked) of the induced draft fan 5 is arranged on the upper part of the activated carbon layer 7; the temperature sensor 3 and the induced draft fan 5 are both electrically connected to an automatic control system (not marked).

[0020] In actual production, as long as the production is running continuously, the exhaust gas treatment system will be running all the time, and the treated low-temperature exhaust gas will be discharged through the exhaust tower 6; therefore, when the automatic control system detects that the surface temperature of the motor is higher than the set temperature through the temperature sensor 3, the automatic control system starts the induced draft fan 5 through instructions to extract the treated low-temperature exhaust gas from the exhaust tower 6 to cool the motor 1; when it is detected that the surface temperature of the motor is lower than the set temperature, the induced draft fan 5 is shut down through instructions to save energy. Through the above processing, the motor temperature is always kept within a certain temperature range, and the life span will not be affected or shutdown caused by overheating, thereby ensuring the continuity of production, and correspondingly ensuring the output and quality of the product.

[0021] It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
