Description

Technical Field

[0001] The utility model belongs to the technical field of reaction kettles, and in particular relates to a reaction kettle for resin production with a temperature control structure. Background Art

[0002] Reactors are broadly understood as containers 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. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc.

[0003] At present, in the process of resin production, a large number of bubbles will be generated after the resin and curing agent are stirred and mixed, and the resin has a high viscosity, so bubbles are easily retained in the liquid. In order to improve the efficiency of resin production and processing, the temperature of the reactor during processing needs to be controlled within a suitable range. However, the existing reactors for resin production do not have a control function, which leads to the temperature of the resin, and the residues adhering to the inner wall of the container will bring inconvenience to the subsequent cleaning, increase the labor intensity of the staff, and have low practicality.

[0004] Therefore, based on the above problems, we designed a reactor for resin production with a temperature control structure. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a resin production reactor with a temperature control structure, which solves the technical problems that the existing resin production reactor has no control function, resulting in high temperature of the resin, and the residues adhering to the inner wall of the container will cause inconvenience in subsequent cleaning, increase the labor intensity of the staff, and have low practicality.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, a resin production reactor with a temperature control structure is provided, comprising a reactor body, a shell reaction cavity of the reactor body is provided with a stirring rod, and an electric heating plate is connected to the bottom;

[0007] Also includes:

[0008] A temperature control component, the temperature control component includes a heat dissipation cavity arranged between the inner and outer walls of the reactor body, a plurality of heat dissipation channels arranged on the shell of the reactor body and communicating with the heat dissipation cavity, a heat dissipation fan connected in the heat dissipation channel and a temperature sensor arranged in the shell reaction cavity of the reactor body, and is used to monitor the temperature of the reaction cavity of the reactor body;

[0009] The cleaning structure comprises a cleaning scraper which is arranged in the reaction cavity of the reactor body and sleeved on the stirring rod, and a scraper which is arranged on the cleaning scraper and contacts the inner wall of the reaction cavity.

[0010] A further improvement is that a driving device is provided on the reactor body, and an output spindle of the driving device is connected to the stirring rod through a coupling.

[0011] A further improvement is that a material pipe is provided on the reactor body, and a flange is provided on the material pipe.

[0012] A further improvement is that the temperature control component also includes a plurality of nozzles arranged in the heat dissipation cavity and the joints are located on the outer wall of the shell, and the nozzles are used to spray the coolant into the reaction cavity of the reactor body to cooperate with the cooling.

[0013] A further improvement is that several of the nozzles are distributed in a circular shape in the heat dissipation cavity, the nozzle of each nozzle is arranged tilted downward, a liquid outlet pipe is provided on the reactor body, the liquid outlet pipe is communicated with the heat dissipation cavity, and a control valve is provided on the liquid outlet pipe for collecting and discharging the sprayed coolant.

[0014] A further improvement is that a one-way exhaust valve is connected to the shell of the reactor body, and the one-way exhaust valve is communicated with the reaction cavity of the shell of the reactor body, which is used to exhaust the reaction cavity of the reactor body, effectively reducing the pressure in the reaction cavity, thereby avoiding certain accidents caused by excessive pressure.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) In the utility model, when the temperature in the reaction cavity of the reactor body exceeds the set value of the temperature sensor during the material heating process, the temperature sensor transmits a signal to the external PLC control system terminal. At this time, the external PLC control system terminal controls to stop the electric heating plate, turns on the heat dissipation fan, starts the liquid pump to extract the coolant in the coolant tank, and sprays it to the outer wall of the reaction cavity. In this way, after the coolant contacts and exchanges with the outer wall of the reaction cavity, it falls into the bottom of the heat dissipation cavity and is discharged from the liquid outlet pipe. At the same time, the negative pressure generated by the heat dissipation fan is used to dissipate the heat introduced into the heat dissipation cavity, and the heat in the reaction cavity is dissipated to cool down the reaction cavity, so that the temperature of the reactor is controlled within a suitable range, the temperature is kept balanced, and the production efficiency of the resin is improved;

[0017] (2) The utility model adopts the design of the cleaning structure. After the production is completed, the stirring rod can synchronously drive the cleaning scraper and the scraper to scrape the residue on the inner wall of the reaction chamber of the reactor body, thereby preventing the resin residue from adhering to the inner wall of the container, reducing the difficulty of subsequent cleaning by the staff, and improving practicality. A one-way exhaust valve is connected to the shell of the reactor body, and the one-way exhaust valve and the shell reaction chamber of the reactor body are connected. In this way, when the pressure in the reaction chamber of the reactor body is too high, the one-way exhaust valve is used to exhaust the gas in the reaction chamber to release the pressure, thereby effectively reducing the pressure in the reaction chamber, thereby avoiding certain accidents caused by excessive pressure.

[0023] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 and Figure 2 As shown, a reactor for resin production with a temperature control structure includes a reactor body 1, a shell reaction cavity of the reactor body 1 is provided with a stirring rod 13, and an electric heating plate 14 is connected to the bottom, and the electric heating plate 14 is filled with a resistance wire;

[0025] The reactor body 1 is provided with a driving device 11, the output spindle of the driving device 11 is connected to the stirring rod 13 through a coupling, and the reactor body 1 is provided with a material pipe 12, and the material pipe 12 is provided with a flange;

[0026] like Figure 2As shown, the implementation also includes: a temperature control component 2, the temperature control component 2 includes a heat dissipation cavity 25 arranged between the inner and outer walls of the reactor body 1, a plurality of heat dissipation channels 21 arranged on the shell of the reactor body 1 and communicating with the heat dissipation cavity 25, a heat dissipation fan 22 connected to the heat dissipation channel 21, and a plurality of nozzles 24 arranged in the heat dissipation cavity 25 and having joints located on the outer wall of the shell;

[0027] The temperature control component 2 further includes a temperature sensor 26, which is disposed in the shell reaction cavity of the reactor body 1 and is used to monitor the temperature of the reaction cavity of the reactor body 1;

[0028] Among them, several nozzles 24 are distributed in a circular shape in the heat dissipation cavity 25, and the nozzle of each nozzle 24 is arranged obliquely downward. A liquid outlet pipe 23 is arranged on the reactor body 1, and the liquid outlet pipe 23 is communicated with the heat dissipation cavity 25. A control valve is arranged on the liquid outlet pipe 23. The temperature is monitored by the temperature sensor 26. When the temperature is too high, the electric heating plate 14 is controlled to stop, and the heat dissipation fan 22 is turned on, and the liquid pump is started to extract the coolant in the coolant tank and spray it to the outer wall of the reaction cavity. In this way, after the coolant contacts and exchanges with the outer wall of the reaction cavity, it falls into the bottom surface of the heat dissipation cavity 25 and is discharged from the liquid outlet pipe 23. At the same time, the negative pressure generated by the heat dissipation fan 22 is used to dissipate the heat introduced into the heat dissipation cavity 25 by the reaction cavity, and the reaction cavity is cooled and cooled, so that the temperature of the reactor body 1 is controlled within a suitable range, the temperature is kept balanced, and the production efficiency of the resin is improved;

[0029] like Figure 2 and Figure 3 As shown, when implemented, it includes: a cleaning structure 3, the cleaning structure 3 includes a cleaning scraper 31 arranged in the reaction cavity of the reactor body 1 and sleeved on the stirring rod 13, and a scraper 32 arranged on the cleaning scraper 31 and in contact with the inner wall of the reaction cavity. The stirring rod 13 synchronously drives the cleaning scraper 31 and the scraper 32 to scrape the residue on the inner wall of the reaction cavity of the reactor body 1, thereby preventing the resin residue from adhering to the inner wall of the container, reducing the difficulty of subsequent cleaning by the staff, and improving practicality;

[0030] In this embodiment, Figure 2 As shown, a one-way exhaust valve 4 is also connected to the shell of the reactor body 1. The one-way exhaust valve 4 is communicated with the reaction cavity of the shell of the reactor body 1 and is used to exhaust the reaction cavity of the reactor body 1, effectively reducing the pressure in the reaction cavity, thereby avoiding certain accidents caused by excessive pressure.

[0031] like Figures 1 to 3As shown, in this embodiment, it is also necessary to explain that before the application document is implemented, the liquid extraction pump pipeline of the external coolant tank is connected to the nozzle 24, and a PLC control system terminal is configured. The temperature sensor 26, the electric heating plate 14, the external liquid extraction pump, and the cooling fan 22 in the application document are all connected to the PLC control system terminal. The PLC control system terminal is a commercially available product of the prior art. The corresponding product is selected in advance before implementation for installation, adjustment and use. The working principle has been disclosed and this application will not elaborate on it.

[0032] In addition, it should be noted that the application document only aims at improving the shortcomings of the existing resin production reactor, which does not have a control function, resulting in the temperature of the resin, and the residues adhering to the inner wall of the container will cause inconvenience to subsequent cleaning, increase the labor intensity of the staff, and low practicality, and does not involve improvements in other aspects; the working principle of the resin production reactor with a temperature control structure is introduced as follows:

[0033] During installation and use, the staff introduces the material into the reaction cavity of the reactor body 1 through the material pipe 12, and then uses the driving device 11 to drive the stirring rod 13 to rotate, so that the stirring rod 13 stirs the material at a uniform speed, and uses the resistance wire filled in the electric heating plate 14 to heat the material in the reactor body 1;

[0034] When the temperature in the reaction cavity of the reactor body 1 exceeds the set value of the temperature sensor 26 during the material heating process, the temperature sensor 26 transmits a signal to the external PLC control system terminal. At this time, the external PLC control system terminal controls to stop the electric heating plate 14, turns on the heat dissipation fan 22, starts the liquid pump to extract the coolant in the coolant tank, and sprays it to the outer wall of the reaction cavity. In this way, the coolant contacts and exchanges with the outer wall of the reaction cavity, falls into the bottom surface of the heat dissipation cavity 25, and is discharged from the liquid outlet pipe 23. At the same time, the negative pressure generated by the heat dissipation fan 22 is used to dissipate the heat introduced into the heat dissipation cavity 25 from the reaction cavity, and the heat is dissipated and cooled in the reaction cavity, so that the temperature of the reactor body 1 is controlled within a suitable range, the temperature is kept balanced, and the production efficiency of the resin is improved.

[0035] Through the design of the cleaning structure 3, after the production is completed, the stirring rod 13 can synchronously drive the cleaning scraper 31 and the scraper 32 to scrape the residue on the inner wall of the reaction cavity of the reactor body 1, thereby preventing the resin residue from adhering to the inner wall of the container, reducing the difficulty of subsequent cleaning for the staff and improving practicality;

[0036] A one-way exhaust valve 4 is connected to the shell of the reactor body 1, and the one-way exhaust valve 4 is communicated with the reaction cavity of the shell of the reactor body 1. In this way, when the pressure in the reaction cavity of the reactor body 1 is too high, the one-way exhaust valve 4 is used to exhaust the gas in the reaction cavity to release the pressure, thereby effectively reducing the pressure in the reaction cavity, thereby avoiding certain accidents caused by excessive pressure.

[0037] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
