Description

Technical Field

[0001] The utility model relates to the field of automatic control devices, in particular to an automatic pressure control device for a polymer dispersant synthesis kettle. Background Art

[0002] Polymer dispersants are also called multifunctional pigment dispersants. The definition of dispersants is that they can reduce the aggregation of solid or liquid particles in the dispersion system. The synthesis reactor is a reactor provided for synthesizing chemical substances under certain temperature and pressure conditions.

[0003] The pressure controller is used for pressure control and pressure protection. The unit has low-pressure and high-pressure controllers to control the working range of the system pressure. When the system pressure reaches the set value, the switch automatically cuts off or connects the circuit. The working principle is that it is an automatic controller that receives a pressure signal and acts. When the system pressure is lower than the lower limit of the set pressure, the controller automatically connects the circuit and the equipment resumes normal operation.

[0004] Most reactions carried out in reactors need to be carried out under a specific air pressure. Therefore, existing reactors are often provided with an adjustable air release device for detecting the working air pressure in the reactor so that the reaction in the reactor can operate normally. However, simple air release devices are often used too frequently. Once the air pressure inside the synthesis reactor fails, the staff may not be able to respond in the first time and cannot perform repairs in time, which is prone to safety failures. At the same time, a simple air compressor is installed inside the cavity, and the data on the top is only used as a simple air pressure detection. It cannot respond to the internal air pressure and cannot issue an alarm. It cannot provide timely reminders after a failure occurs. Utility Model Content

[0024] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A polymer dispersant synthesis reactor pressure automatic control device, such as Figures 1 to 4 As shown, it includes a shell 1, an exhaust pipe 3 is installed on the top of the shell 1, an alarm light 4 is arranged on the top of the exhaust pipe 3, a touch switch 5 is arranged below the alarm light 4, a movable plate 8 is arranged on the inner side of the touch switch 5, and a groove 10 is arranged at the bottom of the movable plate 8.

[0027] The use of the device, when the synthesis reactor device is in use, the raw materials enter the shell 1 from the top feed pipe 2, start the motor, and click to drive the rotating shaft and rotating blade parts inside the shell 1 to rotate the raw materials and stir them evenly. This is a complete set of operation procedures. During the operation, the generated gas will be discharged from the exhaust pipe 3 on the top of the shell 1. At the same time, a discharge part that meets the discharge of the raw materials needs to be installed at the bottom of the shell 1.

[0028] The alarm light 4 at the top is connected to the touch switch 5 at the bottom, and the touch switches 5 are installed at the bottom of the alarm light 4 in sequence. The closer the touch switch 5 is to the alarm light 4, the different frequencies of connection and activation with the alarm light 4 can be selected. The wires installed inside the touch switch 5 are connected to the alarm light 4. After the top touch switch 5 is activated, the alarm light 4 flashes rapidly, and the flashing frequency decreases towards the bottom. Resistors of varying sizes are installed inside each touch switch 5. When contacting different touch switches 5, the flashing frequency of the alarm light 4 is different. The internal air pressure intensity is judged based on the different flashing frequencies. Optionally, the alarm light 4 can be changed from a flashing light reminder to an alarm reminder, and it can still be connected to the touch switch 5. The frequency of the alarm sound can be changed by changing the size of the resistor to achieve the effect of different status reminders. The touch switch 5 needs to be protected by a shell on the outside.

[0029] When the device is in normal use, the airflow flows to the bottom of the exhaust pipe 3 and first contacts the fan blades on the outside of the connecting tube 7. The fan blades are used to connect and fix the connecting tube 7. Because the flow rate of the airflow drives the fan blades to start rotating, the rotation of the fan blades drives the connecting tube 7 to also start rotating. Because the connecting tube 7 and the rotating column 9 are connected by threads, the rotating column 9 is stationary, and the connecting tube 7 spirals up inside the rotating column 9 through the fan blades, pushing the top connected and fixed moving plate 8 upward. With the impact force of the bottom airflow, the faster the fan blade rotates, the higher the distance the moving plate 8 is moved upward, thereby contacting different touch switches 5.

[0030] The grooves 10 on the surface of the rotating column 9 and on the upper and lower sides play a certain buffering role when the airflow moves upward. The grooves 10 are also installed on the surface of the jet slot 6. The groove 10 parts are fixed. The double-layer dislocated grooves 10 parts can achieve simple diversion when the bottom airflow impacts upward. The touch switch 5 at the top can also be installed only within a certain range. The groove 10 parts can still be installed on the surface of the touch switch 5 to disperse the bottom airflow.

[0031] A feed pipe 2 is fixed on the top of the shell 1, an exhaust pipe 3 is arranged on one side of the feed pipe 2, and an exhaust pipe 3 is fixed on the center top of the shell 1. The feed pipe 2 and the exhaust pipe 3 are basic components of the synthesis reactor, and a discharge port also needs to be installed at the bottom.

[0032] A touch switch 5 is fixedly connected to the bottom of the alarm light 4, and a wire connected to the top alarm light 4 is arranged inside the touch switch 5. Similarly, the resistance of each switch is different, decreasing from top to bottom. A wire connected to the top alarm light 4 is fixed inside the touch switch 5, and a jet slot 6 is fixedly connected to the bottom of the touch switch 5, and a groove 10 is arranged on the surface of the jet slot 6.

[0033] A connecting pipe 7 is connected and fixed to the bottom of the movable plate 8, a rotating column 9 is connected to the outside of the connecting pipe 7, a fixed column 11 is fixed to the bottom of the rotating column 9, a groove 10 is fixed to the outside of the rotating column 9, and grooves 10 are fixed to the top and bottom surfaces of the rotating column 9. The groove 10 part is an exhaust hole part on the surface of an ordinary part, and there is no limit on the shape and size as long as the use effect is achieved.

[0034] An air jet groove 6 is arranged inside the exhaust pipe 3 , a groove 10 is arranged on the surface of the air jet groove 6 , a rotating column 9 is arranged inside the air jet groove 6 , and the rotating column 9 is threadedly connected to the connecting pipe 7 .

[0035] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
