Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a reaction kettle with a quantitative adding mechanism. Background Art

[0002] A reactor is a container used for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. It is widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food. It is a container used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc.

[0003] A dispersing wetting agent is a substance that can make solid materials more easily wetted by water. It can wet the solid materials by reducing their surface tension or interfacial tension, so that water can spread on the surface of the solid materials or penetrate into their surface. Wetting agents and dispersants are increasingly used in industrial production as a surfactant. In order to wet the reaction materials without affecting the material properties, it is necessary to add the dispersing wetting agent quantitatively during the reaction production process. The metering instruments such as flow meters currently used for metering on the market do not have high enough metering accuracy and are difficult to adapt to the quantitative addition of small doses of dispersing wetting agents. The manual control of quantitative addition has large errors and is easy to forget and miss, resulting in the phenomenon of adding too much or too little. There is a common problem of inconvenience in adding dispersing wetting agents. For this reason, the present application proposes a reactor with a quantitative addition mechanism.

The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0021] Example

[0022] See also Figures 1 to 4The utility model preferably provides a technical solution: a reactor with a quantitative addition mechanism, including a reactor body 1 and a metering mechanism 8, a feeding cylinder 2 is installed on the top of the reactor body 1, a piston 12 is arranged in the feeding cylinder 2, and a mounting plate 5 is installed on the top of the feeding cylinder 2. The metering mechanism 8 includes a metering turntable 16 rotatably installed on the mounting plate 5, a plurality of infrared calibration plates 17 distributed in an annular shape on the upper surface of the metering turntable 16, and an infrared detector 20 installed on the mounting plate 5 and capable of identifying the infrared calibration plates 17. The mounting plate 5 is also provided with a metering plate 16 that can be measured. The measuring turntable 16 rotates to drive the transmission mechanism 7 that drives the piston 12 to rise and fall. A connecting seat 3 for the flange installation of the feeding barrel 2 is arranged on the top of the reactor body 1, which is convenient for the assembly of the feeding barrel 2. A filling pipe 6 is arranged at the top of the side wall of the feeding barrel 2, which is used to add the dispersed moisturizing agent into the feeding barrel 2. After the filling is completed, the filling pipe 6 is sealed, and the dispersed moisturizing agent inside the feeding barrel 2 is left to stand under the action of pressure. The feeding barrel 2 is transparent, and a capacity scale 4 is engraved on the side wall of the feeding barrel 2, which is convenient for manual observation of the remaining amount and the added amount of the dispersed moisturizing agent inside the feeding barrel 2.

[0023] Through the above-mentioned structural mode, the metering turntable 16 rotates to drive the transmission mechanism 7 to drive the piston 12 to descend, so that the dispersing wetting agent in the feeding barrel 2 can be pushed into the reactor body 1 for addition. During the addition process, the metering turntable 16 rotates, and the infrared calibration plates 17 on the metering turntable 16 pass under the infrared detector 20 in turn and are detected and sensed by the infrared detector 20. During the entire dispersing wetting agent addition process, it is only necessary to record the number of infrared calibration plates 17 sensed and sensed by the infrared detector 20, which can be used to measure the addition amount of the dispersing wetting agent, realize the quantitative addition control of the dispersing wetting agent, and solve the problem that the quantitative addition of the dispersing wetting agent is easy to miss in manual control and the existing flow instruments are difficult to match and apply.

[0024] In this embodiment, a control display 9 is also installed on the mounting plate 5, and a wireless transceiver 10 is installed on the control display 9. The control display 9 is connected to the infrared detector 20 by a line, and the signal sensed by the infrared detector 20 is sent to the control display 9. By wirelessly transmitting and receiving signals using the wireless transceiver 10, remote quantitative addition control of the dispersing wetting agent can be realized.

[0025] As a preferred implementation mode of this embodiment, the transmission mechanism 7 includes a driven gear plate 14 rotatably mounted on the top of the mounting plate 5, a spiral sleeve 15 is fixed on the top of the driven gear plate 14, a spiral rod 11 is spirally penetrated on the spiral sleeve 15, the bottom end of the spiral rod 11 passes through the driven gear plate 14 and the mounting plate 5 and is connected to the piston 12, the transmission mechanism 7 also includes a driving gear 22 coaxially connected to the metering turntable 16, the driving gear 22 is meshed with the driven gear plate 14, a driving motor 18 for driving the metering turntable 16 to rotate is fixedly mounted on the mounting plate 5, a first fixing frame 19 and a second fixing frame 21 are fixed on the upper surface of the mounting plate 5, the infrared detector 20 and the driving motor 18 are respectively fixedly mounted on the first fixing frame 19 and the second fixing frame 21, and starting the driving motor 18 can drive the metering turntable 16 and the driving gear 22 to rotate, which is used to drive the piston 12 to press down to disperse the wetting agent and add the added amount while measuring the added amount.

[0026] In this embodiment, a guide rod 13 extending into the feeding barrel 2 is vertically fixed at the bottom of the mounting plate 5. The guide rod 13 movably penetrates the piston 12 and is used to guide the lifting and lowering of the piston 12, so as to prevent the piston 12 and the screw rod 11 from rotating with the driven toothed disc 14 as much as possible. The diameter of the driving gear 22 is smaller than the diameter of the driven toothed disc 14, which is conducive to the metering turntable 16 driving the driven toothed disc 14 to rotate. The diameter of the metering turntable 16 is larger than the diameter of the driving gear 22, which expands the annular radius of several infrared calibration plates 17, which is conducive to the induction measurement of the infrared calibration plates 17 by the infrared detector 20.

[0027] When in use, the driving motor 18 is started to drive the metering turntable 16 and the driving gear 22 to rotate, and the driven gear 14 is driven to drive the spiral sleeve 15 to rotate by the meshing of the driving gear 22 and the driven gear plate 14, forcing the spiral rod 11 to drive the piston 12 to move upward. After the piston 12 moves to the position above the filling pipe 6, the dispersing wetting agent is added to the feeding barrel 2 through the filling pipe 6, and then the filling pipe 6 is sealed and covered. Under the action of pressure, the dispersing wetting agent is retained in the feeding barrel 2. When it is necessary to add the dispersing wetting agent to the reactor body 1, the driving motor 18 is started in the reverse direction to drive the spiral rod 11 to push the piston 12 downward, and the filling can be filled. The dispersing wetting agent in the barrel 2 is pushed into the reactor body 1 for addition. During this process, the driving motor 18 drives the metering turntable 16 to rotate. The infrared calibration plates 17 on the metering turntable 16 pass under the infrared detector 20 in turn and are detected and sensed by the infrared detector 20. The signal sensed by the infrared detector 20 is sent to the control display 9. During the entire dispersing wetting agent addition process, only the number of infrared calibration plates 17 sensed by the infrared detector 20 needs to be recorded, which can be used to measure the amount of dispersing wetting agent added. Then, the wireless transceiver 10 is used to wirelessly transmit and receive signals, so as to realize remote quantitative addition control of the dispersing wetting agent.
